    The PEP-II project has two storage rings. The HER (High Energy Ring) has up to 1.48 A of electron beam at 9 GeV, and the LER (Low Energy Ring) has up to 2.14 A of positron beam at 3.1 GeV. To protect the HER and LER beam lines in the event of a ring component failure, each ring has an abort kicker system which directs the beam into a dump when a failure is detected. Due to the high current of the beams, the beam kick is tapered from 100% to 80% in 7.33 uS (the beam transit time around the time). This taper distributes the energy evenly across the window which separates the ring from the beam dump such that the window is not damaged. The abort kicker trigger is synchronized with the ion clearing gap of the beam allowing for the kicker field to rise from 0-80% in 370 nS. This report discusses the design of the system controls, interlocks, power supplies, and modulator.

    As one of the most critical system for RHIC operation, the beam abort kicker system has to be highly available, reliable, and stable for the entire operating range. Along with the RHIC commission and operation, consistent efforts have been spend to cope with immediate issues as well as inherited design issues. Major design changes have been implemented to achieve the higher operating voltage, longer high voltage hold-off time, fast retriggering and redundant triggering, and improved system protection, etc. Recent system test has demonstrated for the first time that both blue ring and yellow ring beam abort systems have achieved more than 24 hours hold off time at desired operating voltage. In this paper, we report break down, thyratron reverse arcing, and to build a fast re-trigger system to reduce beam spreading in event of premature discharge.

    Through more than a decade of operation, we have noticed the phenomena of beam loss induced kicker instability in the RHIC beam abort systems. In this study, we analyze the short term beam loss before abort kicker pre-fire events and operation conditions before capacitor failures. Beam loss has caused capacitor failures and elevated radiation level concentrated at failed end of capacitor has been observed. We are interested in beam loss induced radiation and heat dissipation in large oil filled capacitors and beam triggered thyratron conduction. We hope the analysis result would lead to better protection of the abort systems and improved stability of the RHIC operation.

    The high intensity proton bunches (~2.5x1011 p/bunch ) circulating in RHIC increase the temperature of the ferrite-made RHIC-abort-kickers above the Curie point; as a result, the kickers cannot provide the required field to abort the beam at the beam dump. A team of experts in the CAD department worked on modifying the design of the window-frame RHIC-abort kicker to minimize the hysteresis losses responsible for the increase of the ferrite’s temperature. In this technical note we report some results from the study of two possible modifications of the window-frame RHIC-abort kicker, and we compare these results with those of a propose C-type RHIC-abort kicker. We also include an Appendix where we describe a method which may further reduce the hysteresis losses of the window-frame kicker.

    In recent RHIC operational runs, planned and unplanned pre-fire triggered beam aborts have been observed that resulted in quenches of SC main ring magnets, indicating a weakened magnet kick strength due to beam-induced ferrite heating. An improvement program was initiated to reduce the longitudinal coupling impedance with changes to the ferrite material and the eddy-current strip geometry. Results of the impedance measurements and of magnet heating tests with CMD10 ferrite up to 190°C are reported. All 10 abort kickers in the tunnel have been modified and were provided with a cooling system for the RUN 15.

    A gas discharge switch EEV HX3002 is being evaluated at Brookhaven National Laboratory as a possible candidate of RHIC Beam Abort Kicker modulator main switch. At higher beam energy and higher beam intensity, the switch stability becomes very crucial. The hollow anode thyratron used in the existing system is not rated for long reverse current conduction. The reverse voltage arcing caused thyratron hold-off voltage de-rating has been the main limitation of the system operation. To improve the system reliability, a new type of gas discharge switch has been suggested by Marconi Applied Technology for its reverse conducting capability.

    2009-09-01

    In face of the new upgrades for RHIC the longitudinal impedance of the machine plays an important role in setting the threshold for instabilities and the efficacy of some systems. In this paper we describe the measurement of the longitudinal impedance of the abort kicker for RHIC as well as computer simulations of the structure. The impedance measurement was done by the S{sub 21} wire method covering the frequency range from 9 kHz to 2.5 GHz. We observed a sharp resonance peak around 10 MHz and a broader peak around 20 MHz in both, the real and imaginary part, of the Z/n. These two peaks account for a maximum imaginary longitudinal impedance of j15 {Omega}, a value an order of magnitude larger than the estimated value of j0.2 {Omega}, which indicates that the kicker is one of the main sources of longitudinal impedance in the machine. A computer model was constructed for simulations in the CST MWS program. Results for the magnet input and the also the beam impedance are compared to the measurements. A more detail study of the system properties and possible changes to reduce the coupling impedance are presented.

    The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory is the world largest superconducting accelerator for nuclear energy research. Particle beams traveling in opposite directions in two accelerator rings, Blue and Yellow, collide at six interaction regions to create phenomena of the early universe. There are more than 1700 superconducting magnets and very sophisticate and delicate large detectors inside the RHIC tunnel. With high beam intensity and ultra high beam energy, an inadvertent loss of beam can result severe damage to the superconducting magnets and detectors. Beam abort kickers are used to remove beam safely from the ring. The large inductive load, high current capability, short beam gap, and high reliability are the challenging issues of this system design. With high intensity and high momentum beam operation, it is desirable to have all high voltage modulators located outside of RHIC tunnel. However, to generate 22 kA output current per modulator with fast rise time, a conventional low impedance PFN and matched transmission cable design can push the operation voltage easily into 100 kV range. The large quantity of high voltage pulse transmission cables required by conventional design is another difficult issue. Therefore, the existing system has all ten high voltage modulators located inside RHIC tunnel. More than a hundred plastic packaged mineral oil filled high voltage capacitors raise serious concerns of fire and smoking threats. Other issues, such as kicker misfire, device availability in the future, and inaccessibility during operation, also demand an engineering solution for the future upgrade. In this paper, we investigate an unconventional approach to meet the technical challenges of RHIC beam abort system. The proposed design has all modulators outside of the RHIC tunnel. It will transmit output pulse through high voltage cables. The modulators will utilize solid-state switches, and operate at a maximum voltage in 30 to

    The design and installation of the Linear Coherent Light Source [1] at SLAC National Accelerator Laboratory has included the development of a kicker system for selective beam bunch dumping. The kicker is based on an LC resonant topology formed by the 50 uF energy storage capacitor and the 64 uH air core magnet load which has a sinusoidal pulse period of 400us. The maximum magnet current is 500 A. The circuit is weakly damped, allowing most of the magnet energy to be recovered in the energy storage capacitor. The kicker runs at a repetition rate of 120Hz. A PLC-based control system provides remote control and monitoring of the kicker via EPICS protocol. Fast timing and interlock signals are converted by discrete peak-detect and sample-hold circuits into DC signals that can be processed by the PLC. The design and experimental characterization of the system are presented.

    The SNS Extraction Fast Kicker System is a very high power, high repetition rate pulsed power system. It was design and developed at Brookhaven National Laboratory. This system will consist of fourteen identical high voltage, high current modulators, and their auxiliary control and charging systems. The modulators will drive fourteen extraction magnet sections located inside of the SNS accumulator ring. The required kicker field rise time is 200 ns, a pulse flattop of 700 ns, a pulse repetition rate of 60 pulse-per-second. A 2500 Ampere per modulator output is required to reach the extraction kicker magnetic field strength. This design features a Blumlein Pulse-Forming-Network based topology, a low beam impedance termination, a fast current switching thyratron, and low inductance capacitor banks. It has a maximum charging voltage of 50kV, an open circuit output of 100kV, and a designed maximum pulsed current output of 4kA per modulator. The overall system output will be multiple GVA with 60 Pulse-per-second repetition rate. A prototype modulator has been successfully built and tested well above the SNS requirement. The modulator system production is in progress.

    The installation of electrostatic separator modules at B48 and C17 in the Tevatron necessitates changes to the Tevatron abort system. There will no longer be room for either the proton or antiproton kicker magnets used in the present system. The kickers at C17 will be permanently removed. The kickers at B48 will be temporarily removed for collider operation and will be replaced for fixed target operation. The existing proton abort system will remain unchanged during fixed target operation. This note describes a proposed abort system for operation in the collider mode for 22 on 22 bunches and provides details of specifications for the required components. In certain cases, for example in the case of the pulsers for the magnets and the absorber assembly, system components are designed with the option of upgrading to 44 on 44 bunch operation in mind. 8 refs., 14 figs.

    A kicker system plays an important role in beam extraction and injection for a ring-like accelerator. The kicker system in the Heavy Ion Research Facility in Lanzhou (HIRFL) is used for beam extraction and injection between two cooling storage rings (CSRs). The system consists of two parts: one part is used for beam extraction from the CSR/main (CSRm), and the other is used for beam injection into the CSR/experimental (CSRe). To meet the requirements of special physics experiments, we upgraded the kicker control system. In this upgraded system, the position of the beam bunches can be determined by measuring the phase of the radio frequency (RF) signal in real time because each beam bunch is synchronized with the RF signal. The digital timing control and delay regulatory function, which are based on a new design using ARM+DSP+FPGA technology, achieved a precision of 2.5 ns, which is a significant improvement over old system's precision of 5 ns. In addition, this system exhibits a better anti-interference capability. Moreover, the efficiency of beam extraction can be enhanced, and the accuracy of the reference voltage setting can reach as low as 0.1%, compared to 2% for the old system.

    The Brookhaven AGS Booster has a very successful commissioning period in June 1991. The third phase of that commissioning was a beam extraction test. The Booster extraction fast kicker (F3) deflected a 1.2 GeV proton beam from the Booster circulating orbit into the extraction septum aperture, partially down the extraction line to a temporary beam stop. Now, the Booster is committed to the AGS operations program for both heavy ion and proton beams. Thus, the Booster extraction and the corresponding AGS injection systems must operate routinely up to a pulse repetition frequency of 7.5 Hertz, and up to a beam energy of 1.5 Gev. The injection fast kicker is located in the A5 section of the AGS ring and is used to deflect the proton or heavy ion beam into its final AGS closed orbit. A distinctive feature of the AGS injection fast kicker modulators is the tail-bitting function required for proton beam injection. This enables the system to produce a fast current fall time to go along with the high current pulse amplitude with a fast rise time. The AGS injection fast kicker system has three pulse modulators, and each modulator consists of two thyratrons. The main PFN thyratrons switch on the current, and the tail bitting thyratrons are used to force the magnet current to decrease rapidly. Two digital pulse delay generators are used to align the main thyratrons and the tail bitting thyratrons respectively. The system has been tested and installed. The final commissioning of the Booster to AGS beam transfer line and injection is currently being undertaken. In this article, the system design, realization techniques and performance data will be presented.

    The temperature stability of the kicker magnet termination resistor assembly directly affects the field flatness and amplitude stability. Comprehensive thermal enhancements were made to the existing Main Injector resistor assembly design to satisfy NuMI performance specifications. Additionally, a fluid-processing system utilizing Fluorinert{reg_sign} FC-77 high-voltage dielectric was built to precisely control the setpoint temperature of the resistor assembly from 70 to 120F, required to maintain constant resistance during changing operational modes. The Fluorinert{reg_sign} must be continually processed to remove hazardous breakdown products caused by radiation exposure to prevent chemical attack of system components. Design details of the termination resistor assembly and Fluorinert{reg_sign} processing system are described. Early performance results will be presented.

    An all solid-state kicker pulser for a proton radiography system has been designed. Multiple solid-state modulators stacked in an inductive-adder configuration are utilized in this kicker pulser design. Each modulator is comprised of multiple metal-oxide-semiconductor field-effect transistors (MOSFETs) which quickly switch the energy storage capacitors across a magnetic induction core. Metglas is used as the core material to minimize loss. Voltage from each modulator is inductively added by a voltage summing stalk. A circuit model of a prototype inductive adder kicker pulser modulator has been developed to predict the performance of the pulser modulator. The modeling results are compared with experimental data.

    A kicker control system is used for beam extraction and injection between two cooling storage rings (CSRs) at the Heavy Ion Research Facility in Lanzhou (HIRFL). To meet the requirements of special physics experiments, the kicker controller has been upgraded, with a new controller designed based on ARM+DSP+FPGA technology and monolithic circuit architecture, which can achieve a precision time delay of 2.5 ns. In September 2014, the new kicker control system was installed in the kicker field, and the test experiment using the system was completed. In addition, a pre-trigger signal was provided by the controller, which was designed to synchronize the beam diagnostic system and physics experiments. Experimental results indicate that the phenomena of “missed kick” and “inefficient kick” were not observed, and the multichannel trigger signal delay could be adjusted individually for kick power supplies in digitization; thus, the beam transport efficiency was improved compared with that of the original system. The fast extraction and injection experiment was successfully completed based on the new kicker control systems for HIRFL. Supported by National Natural Science Foundation of China (U1232123)

    The fast extraction kicker system is one of the most important accelerator components and the main source of impedance in the Rapid Cycling Synchrotron of the China Spallation Neutron Source. It is necessary to understand the kicker impedance before its installation into the tunnel. Conventional and improved wire methods are employed in the impedance measurement. The experimental results for the kicker impedance are explained by comparison with simulation using CST PARTICLE STUDIO. The simulation and measurement results confirm that the window-frame ferrite geometry and the end plate are the important structures causing coupling impedance. It is proved in the measurements that the mismatching from the power form network to the kicker leads to a serious oscillation sideband of the longitudinal and vertical impedance and the oscillation can be reduced by ferrite absorbing material.

    The SLAC 2-mile linear accelerator uses a wide variety of pulse kicker systems that require high voltage cable and connectors to deliver pulses from the drivers to the magnet loads. Many of the drivers in the SLAC kicker systems use cable lengths up to 80 feet and are required to deliver pulses up to 40 kV, with rise and fall time on the order of 20 ns. Significant pulse degradation from the cable and connector assembly cannot be tolerated. Other drivers are required to deliver up to 80 kV, 20 {mu}s pulses over cables 20 feet long. Several combinations of an applicable high voltage cable and matching connector have been used at SLAC to determine the optimum assembly that meets the necessary specifications and is reliable. 14 refs., 3 figs., 1 tab.

    The J-2X is an expendable liquid hydrogen (LH2)/liquid oxygen (LOX) gas generator cycle rocket engine that is currently being designed as the primary upper stage propulsion element for the new NASA Ares vehicle family. The J-2X engine will contain abort logic that functions as an integral component of the Ares vehicle abort system. This system is responsible for detecting and responding to conditions indicative of impending Loss of Mission (LOM), Loss of Vehicle (LOV), and/or catastrophic Loss of Crew (LOC) failure events. As an earth orbit ascent phase engine, the J-2X is a high power density propulsion element with non-negligible risk of fast propagation rate failures that can quickly lead to LOM, LOV, and/or LOC events. Aggressive reliability requirements for manned Ares missions and the risk of fast propagating J-2X failures dictate the need for on-engine abort condition monitoring and autonomous response capability as well as traditional abort agents such as the vehicle computer, flight crew, and ground control not located on the engine. This paper describes the baseline J-2X abort subsystem concept of operations, as well as the development process for this subsystem. A strategy that leverages heritage system experience and responds to an evolving engine design as well as J-2X specific test data to support abort system development is described. The utilization of performance and failure simulation models to support abort system sensor selection, failure detectability and discrimination studies, decision threshold definition, and abort system performance verification and validation is outlined. The basis for abort false positive and false negative performance constraints is described. Development challenges associated with information shortfalls in the design cycle, abort condition coverage and response assessment, engine-vehicle interface definition, and abort system performance verification and validation are also discussed.

  9. Abortion in Iranian legal system: a review.

    Abortion traditionally means, "to miscarry" and is still known as a problem which societies has been trying to reduce its rate by using legal means. Despite the pregnant women and fetuses have being historically supported; abortion was firstly criminalized in 1926 in Iran, 20 years after establishment of modern legal system. During next 53 years this situation changed dramatically, so in 1979, the time of Islamic Revolution, aborting fetuses before 12 weeks and therapeutic abortion (TA) during all the pregnancy length was legitimate, based on regulations that used medical justification. After 1979 the situation changed into a totally conservative and restrictive approach and new Islamic concepts as "Blood Money" and "Ensoulment" entered the legal debates around abortion. During the next 33 years, again a trend of decriminalization for the act of abortion has been continuing. Reduction of punishments and omitting retaliation for criminal abortions, recognizing fetal and maternal medical indications including some immunologic problems as legitimate reasons for aborting fetuses before 4 months and omitting the fathers' consent as a necessary condition for TA are among these changes. The start point for this decriminalization process was public and professional need, which was responded by religious government, firstly by issuing juristic rulings (Fatwas) as a non-official way, followed by ratification of "Therapeutic Abortion Act" (TAA) and other regulations as an official pathway. Here, we have reviewed this trend of decriminalization, the role of public and professional request in initiating such process and the rule-based language of TAA.

    The SNS (Spallation Neutron Source) accumulator ring Extraction System consists of a Fast kicker and a Lambertson Septum magnet. The proposed design will use 14 kicker magnets powered by an Extraction Kicker Power Supply System. They will eject the high power beam from the SNS accumulator ring into RTBT (Ring to Target Beam Tunnel) through a Lambertson Septum magnet. This paper describes some test results of the SNS Extraction Kicker power supply prototype. The high repetition rate of 60 pulse per second operation is the challenging part of the design. In the prototype testing, a 3 kA damp current of 700ns pulse-width, 200 nS rise time and 60 Hz repetition rate at 32 kV PFN operation voltage has been demonstrated. An Extraction kicker power supply system design diagram is depicted.

    The historical and current (1969) abortion laws in France as well as those in other Western countries are analyzed. France has had a series of punitive abortion codes since the Napoleonic Code of 1810 prescribing solitary confinement for the woman. The reforms of 1920 and 1923 made provocation of abortion or contraceptional propaganda a "crime" (felony), later a "delit" (misdemeanor), called for trial before magistr ate instead of jury, but resulted in only about 200 convictions a year. The decree of 1939 extended the misdemeanor to women who aborted even if they were not pregnant, and provided for professional licenses such as that of surgeon or pharmacist to be suspended. The law of 1942 made abortion a social crime and increased the maximum penalty to capital punishment, which was exercised in 2 cases. About 4000 per year were convicted from 1942-1944. Now the law still applies to all who intend to abort, whether or not pregnant or successful, but punishemnt is limited to 1-5 years imprisonment, and 72,000 francs fine, or suspension of medical practice for 5 years. About 500 have been convicted per year. Since 1955 legal abortion has been available (to about 130 women over 4 years) if it is the only means to save the woman's life. Although pregnancy tests are controlled, the population desregards the law by resorting to clandestine abortion. The wealthy travel to Switzerland (where 68% of legal abortions are done on French women) or to England. Numbers are estimated by the French government at 250,000-300,000 per year, or 1 for every 2 live births, but by hospital statistics at 400,000-1,000,000 per year. The rest of the review covers abortion laws in Scandinavian, Central European, and individual US states as of 1969.

    The review by Aileen F. Connon of Abortion by Potts, Diggory and Peel (Journal, February 10) made interesting reading, especially her quotation of the "facinating statistical information" that Australia has 11.5 million people and 45,000 to 90,000 criminal abortions a year. These are rather wide upper and lower confidence limits. One wonders what other information the authors have included that is of the same standard of accuracy. On the other hand, Malcolm Potts told me some years ago that the experience of his parent organization, the International Planned Parenthood Federation, with the IUD in India was a disaster. That I could well believe. Seeing some of the victims, the sight would indeed be enough to stir the stony heart of the most inhuman consultant gynaecologist. There is in Australia, and indeed in the world, an increasing number of doctors who are revolted by the activities of the International Planned Parenthood Federation and its affiliates which aggressively promote abortion as "an acceptable method of fertility control," and even as the primary method. These are a cross-section of the profession and include some of its most distinguished and erudite members who would be both competent and happy to review a book such as Abortion by Potts et alii from a pro-life point of view. Could I suggest that in future your book reviews and editorials include some well informed commentaries from doctors representing that heretofore silent group? I am holding a long and growing list of Australian doctors who have signed the "Declaration of Doctors," thus explicitly spelling out their respect for human life from the first moment of biological existence to that of natural death. Their services are available on request.

    I would like to take issue with Dr Colin Brewer's statements concerning intrauterine contraceptive devices and abortion (11 August, p 389). I agree that logically there is no distinction between IUCDs, and other abortifacients used early in pregnancy, and abortion methods used later in pregnancy. However, I disagree with his statement that to make illegal IUCDs and similar methods out of an "obsessive concern for microscopic forms of life" would be "absurd." Firstly, size has never been a criterion for the presence or absence of life, or of its importance. Surely Dr Brewer, MPs, and the public would be outraged by anything less than obsessively careful handling of, say, rabies or smallpox viruses in laboratories. Do not the products of conception, with the full potential of a human being unless actively interfered with by other men (neglecting normal fetal wastage), deserve any less concern? Secondly, mortality should not be determined by practicalities; rather morality should determine one's actions. The question of whether IUCDs and other such procedures should remain legal or be made illegal should not be determined by their efficacy, popularity, or economy. I agree fully with Dr Brewer--abortion is a moral issue and it is a pity that the BMF has not raised the moral issues at stake. Particularly so, as Lord Denning put it "...without morality there can be no law." I personally subscribe to the Hippocratic Oath. PMID:497769

    Two extraction kicker magnet assemblies that contain seven individual pulsed magnet modules each will kick the proton beam vertically out of the SNS accumulator ring into the aperture of the extraction Lambertson septum magnet. The proton beam then travels to the 1.4 MW SNS target assembly. The 14 kicker magnets and major components of the kicker assembly have been fabricated in BNL. The inner surfaces of the kicker magnets were coated with TiN to reduce the secondary electron yield. All 14 PFN power supplies have been built, tested and delivered to OWL. Before final installation, a partial assembly of the kicker system with three kicker magnets was assembled to test the functions of each critical component in the system. In this paper we report the progress of the construction of the kicker components, the TIN coating of the magnets, the installation procedure of the magnets and the full power test of the kicker with the PFN power supply.

  6. Full-Envelope Launch Abort System Performance Analysis Methodology

    NASA Technical Reports Server (NTRS)

    Aubuchon, Vanessa V.

    2014-01-01

    The implementation of a new dispersion methodology is described, which dis-perses abort initiation altitude or time along with all other Launch Abort System (LAS) parameters during Monte Carlo simulations. In contrast, the standard methodology assumes that an abort initiation condition is held constant (e.g., aborts initiated at altitude for Mach 1, altitude for maximum dynamic pressure, etc.) while dispersing other LAS parameters. The standard method results in large gaps in performance information due to the discrete nature of initiation conditions, while the full-envelope dispersion method provides a significantly more comprehensive assessment of LAS abort performance for the full launch vehicle ascent flight envelope and identifies performance "pinch-points" that may occur at flight conditions outside of those contained in the discrete set. The new method has significantly increased the fidelity of LAS abort simulations and confidence in the results.

    This presentation provides a concise overview of the highly successful Orion Pad Abort 1 (PA-1) flight test, and the three rocket motors that contributed to this success. The primary purpose of the Orion PA-1 flight was to help certify the Orion Launch Abort System (LAS), which can be utilized in the unlikely event of an emergency on the launchpad or during mission vehicle ascent. The PA-1 test was the first fully integrated flight test of the Orion LAS, one of the primary systems within the Orion Multi-Purpose Crew Vehicle (MPCV). The Orion MPCV is part of the architecture within the Space Launch System (SLS), which is being designed to transport astronauts beyond low-Earth orbit for future exploration missions. Had the Orion PA-1 flight abort occurred during launch preparations for a real human spaceflight mission, the PA-1 LAS would have saved the lives of the crew. The PA-1 flight test was largely successful due to the three solid rocket motors of the LAS: the Attitude Control Motor (ACM); the Jettison Motor (JM); and the Abort Motor (AM). All three rocket motors successfully performed their required functions during the Orion PA-1 flight test, flown on May 6, 2010 at the White Sands Missile Range in New Mexico, culminating in a successful demonstration of an abort capability from the launchpad.

    Professor Peter Hungerford (25 August, p 496) says that he is fed up with semantic arguments about abortion which ignore reality. He then invokes two major fantasies of the last decade, those of sexual equality and the woman's right to choose. The second of these has become an article of faith to many pro-abortionists and its credentials should be examined. Whence does this right derive? A woman takes part in a more or less pleasurable activity with a man and then, without her volition, with no conscious effort on her part at all, the miraculous occurs and a new life comes into being. How does she have the right to destroy this new life? The argument is usually to the effect that it belongs to her and could not survive without her: "It's mine and I can do what I like with it." Of course, it is true that a fetus cannot survive without the support of its mother; no more could Professor Hungerford or I survive without the support of our fellow men who provide us with food, drink, and clothing, but that does not give them the right to kill us. The claim to possession, the assumption that the fetus is owned by its mother involves, I believe, a semantic error. In a sense, the fetus is "hers" in that it is growing inside her, even though she did not create it. Likewise, her husband is hers because joined to her by marriage and her country is hers because she lives there, although she does not own either of them and certainly has no right to destroy them. The life growing inside the mother is not hers in the same way that a cardigan she has bought or knitted for herself is hers. It is the consideration of semantics that protects us from the "realities" of such as Professor Hungerford.

    During the RHIC Au-run in 2001 the 200 MHz storage cavity system was used for the first time. The rebucketing procedure caused significant beam debunching in addition to amplifying debunching due to other mechanisms. At the end of a four hour store, debunched beam could account for approximately 30%-40% of the total beam intensity. Some of it will be in the abort gap. In order to minimize the risk of magnet quenching due to uncontrolled beam losses at the time of a beam dump, a combination of a fast transverse kicker and copper collimators were used to clean the abort gap. This report gives an overview of the gap cleaning procedure and the achieved performance.

    2015-01-01

    The Orion Launch Abort System Office is taking part in flight testing to enable certification that the system is capable of delivering the astronauts aboard the Orion Crew Module to a safe environment during both nominal and abort conditions. Orion is a NASA program, Exploration Flight Test 1 is managed and led by the Orion prime contractor, Lockheed Martin, and launched on a United Launch Alliance Delta IV Heavy rocket. Although the Launch Abort System Office has tested the critical systems to the Launch Abort System jettison event on the ground, the launch environment cannot be replicated completely on Earth. During Exploration Flight Test 1, the Launch Abort System was to verify the function of the jettison motor to separate the Launch Abort System from the crew module so it can continue on with the mission. Exploration Flight Test 1 was successfully flown on December 5, 2014 from Cape Canaveral Air Force Station's Space Launch Complex 37. This was the first flight test of the Launch Abort System preforming Orion nominal flight mission critical objectives. The abort motor and attitude control motors were inert for Exploration Flight Test 1, since the mission did not require abort capabilities. Exploration Flight Test 1 provides critical data that enable engineering to improve Orion's design and reduce risk for the astronauts it will protect as NASA continues to move forward on its human journey to Mars. The Exploration Flight Test 1 separation event occurred at six minutes and twenty seconds after liftoff. The separation of the Launch Abort System jettison occurs once Orion is safely through the most dynamic portion of the launch. This paper will present a brief overview of the objectives of the Launch Abort System during a nominal Orion flight. Secondly, the paper will present the performance of the Launch Abort System at it fulfilled those objectives. The lessons learned from Exploration Flight Test 1 and the other Flight Test Vehicles will certainly

    Measured longitudinal and calculated transverse beam impedance is presented for the short kicker magnets being installed in the Fermilab Recycler. Fermi drawing number ME-457159. The longitudinal impedance was measured with a stretched wire and the Panofsky equation was used to estimate the transverse impedance. The impedance of 3319 meters (the Recycler circumference) of stainless vacuum pipe is provided for comparison. Although measurements where done to 3GHz, impedance was negligible above 30MHz. The beam power lost to the kicker impedance is shown for a range of bunch lengths. The measurements are for one kicker assuming a rotation frequency of 90KHz. Seven of these kickers are being installed.

    2007-01-01

    This paper describes initial flight performance analyses conducted early in the Orion Project to support concept feasibility studies for the Crew Exploration Vehicle s Launch Abort System (LAS). Key performance requirements that significantly affect abort capability are presented. These requirements have implications on sizing the Abort Motor, tailoring its thrust profile to meet escape requirements for both launch pad and high drag/high dynamic pressure ascent aborts. Additional performance considerations are provided for the Attitude Control Motor, a key element of the Orion LAS design that eliminates the need for ballast and provides performance robustness over a passive control approach. Finally, performance of the LAS jettison function is discussed, along with implications on Jettison Motor sizing and the timing of the jettison event during a nominal mission. These studies provide an initial understanding of LAS performance that will continue to evolve as the Orion design is matured.

    Beam transfer from the AGS to RHIC is performed in single-bunch mode. Close spacing of the bunches in the collider requires an injection kicker with a rise time of <95 nsec, suggesting adoption of a travelling wave solution. The required vertical kick of 0.186 T.m is provided by 4 units, each 1.12 m long with a 48.4× 48.4 mm aperture and operated at 1.6 kA. The kicker is constructed as a ``C'' cross section magnet, in which ferrite and high-permittivity ( ~ 100) dielectric sections alternate. The dielectric blocks provide the capacity necessary for the nominally 25 Ohm characteristic impedance of the travelling wave structure, but impose the practical limit on the peak voltage, and thus current, achievable. Computer studies to minimize local electric field enhancements resulted in a configuration capable of holding >50 kV, with adequate safety margin over the nominal 40 kV. Tests indicated the possibility of lowering the nominal voltage by operating mismatched into 20 Ohm terminations without degrading the pulse shape. In this paper, the experience gained in the fabrication of the four kicker units for the ``Sextant Test'' and the results from various single-unit tests and operation in beam are reported.

  16. Using multiple pickups for transverse feedback systems and optimal pickups-kicker placement for noise power minimization

    NASA Astrophysics Data System (ADS)

    Alhumaidi, M.; Zoubir, A. M.

    2014-10-01

    We propose a new concept to use multiple pickups for estimating the beam displacement at the position 90° before the kicker is activated. The estimated values should be the driving feedback signal. The signals from the different pickups are delayed such that they correspond to the same bunch. Subsequently, a weighted sum of the delayed signals is suggested as an estimator of the feedback correction signal. The weighting coefficients are calculated in order to achieve an unbiased estimator, i.e., the output corresponds to the actual beam displacement at the position 90° before the kicker for non-noisy pickup signals. Furthermore, the estimator must provide the minimal noise power at the output among all linear unbiased estimators. This proposed concept is applied in our new approach to find optimal places for the pickups and the kicker around the accelerator ring such that the noise effect on the feedback quality is minimized. Finally, simulation results for the heavy ions synchrotrons SIS 18 at the GSI are shown.

  17. MI Gap Clearing Kicker Magnet Design Review

    SciTech Connect

    Jensen, Chris; /Fermilab

    2008-10-01

    The kicker system requirements were originally conceived for the NOvA project. NOvA is a neutrino experiment located in Minnesota. To achieve the desired neutrino flux several upgrades are required to the accelerator complex. The Recycler will be used as a proton pre-injector for the Main Injector (MI). As the Recycler is the same size as the MI, it is possible to do a single turn fill ({approx}11 {micro}sec), minimizing the proton injection time in the MI cycle and maximizing the protons on target. The Recycler can then be filled with beam while the MI is ramping to extract beam to the target. To do this requires two new transfer lines. The existing Recycler injection line was designed for 10{pi} pbar beams, not the 20{pi} proton beams we anticipate from the Booster. The existing Recycler extraction line allows for proton injection through the MI, while we want direct injection from the Booster. These two lines will be decommissioned. The new injection line from the MI8 line into the Recycler will start at 848 and end with injection kickers at RR104. The new extraction line in the RR30 straight section will start with a new extraction kicker at RR232 and end with new MI injection kickers at MI308. Finally, to reduce beam loss activation in the enclosure, a new gap clearing kicker will be used to extract uncaptured beam created during the slip stack injection process down the existing dump line. It was suggested that the MI could benefit from this type of system immediately. This led to the early installation of the gap clearing system in the MI, followed by moving the system to Recycler during NOvA. The specifications also changed during this process. Initially the rise and fall time requirements were 38 ns and the field stability was {+-}1%. The 38 ns is based on having a gap of 2 RF buckets between injections. (There are 84 RF buckets that can be filled from the Booster for each injection, but 82 would be filled with beam. MI and Recycler contain 588 RF buckets

    2011-01-01

    This study investigated a potential Launch Abort System (LAS) Concept of Operations and abort parachute architecture. The purpose of the study was to look at the concept of jettisoning the LAS tower forward (Reverse LAS or RLAS) into the free-stream flow rather than after reorienting to a heatshield forward orientation. A hypothesized benefit was that due to the compressed timeline the dynamic pressure at main line stretch would be substantially less. This would enable the entry parachutes to be designed and sized based on entry loading conditions rather than the current stressing case of a Pad Abort. Ultimately, concerns about the highly dynamic reorientation of the CM via parachutes, and the additional requirement of a triple bridle attachment for the RLAS parachute system, overshadowed the potential benefits and ended this effort.

    The Large Hadron Collider (LHC) beam-dump system relies on extraction kickers that need 3 microseconds to rise to their nominal field. Since particles transiting the kickers during the rise will not be dumped properly, the proton population in this interval must always remain below quench and damage limits. A specific monitor to measure the particle population of this gap has been designed based on the detection of synchrotron radiation using a gated photomultiplier. Since the quench and damage limits change with the beam energy, the acceptable population in the abort gap and the settings of the monitor must adapt accordingly. This paper presents the design of the monitor, the calibration procedure and the detector performance with beam.

  20. A Proposed Ascent Abort Flight Test for the Max Launch Abort System

    NASA Technical Reports Server (NTRS)

    Tartabini, Paul V.; Gilbert, Michael G.; Starr, Brett R.

    2016-01-01

    The NASA Engineering and Safety Center initiated the Max Launch Abort System (MLAS) Project to investigate alternate crew escape system concepts that eliminate the conventional launch escape tower by integrating the escape system into an aerodynamic fairing that fully encapsulates the crew capsule and smoothly integrates with the launch vehicle. This paper proposes an ascent abort flight test for an all-propulsive towerless escape system concept that is actively controlled and sized to accommodate the Orion Crew Module. The goal of the flight test is to demonstrate a high dynamic pressure escape and to characterize jet interaction effects during operation of the attitude control thrusters at transonic and supersonic conditions. The flight-test vehicle is delivered to the required test conditions by a booster configuration selected to meet cost, manufacturability, and operability objectives. Data return is augmented through judicious design of the boost trajectory, which is optimized to obtain data at a range of relevant points, rather than just a single flight condition. Secondary flight objectives are included after the escape to obtain aerodynamic damping data for the crew module and to perform a high-altitude contingency deployment of the drogue parachutes. Both 3- and 6-degree-of-freedom trajectory simulation results are presented that establish concept feasibility, and a Monte Carlo uncertainty assessment is performed to provide confidence that test objectives can be met.

  1. Testing Strategies and Methodologies for the Max Launch Abort System

    Schaible, Dawn M.; Yuchnovicz, Daniel E.

    2011-01-01

    The National Aeronautics and Space Administration (NASA) Engineering and Safety Center (NESC) was tasked to develop an alternate, tower-less launch abort system (LAS) as risk mitigation for the Orion Project. The successful pad abort flight demonstration test in July 2009 of the "Max" launch abort system (MLAS) provided data critical to the design of future LASs, while demonstrating the Agency s ability to rapidly design, build and fly full-scale hardware at minimal cost in a "virtual" work environment. Limited funding and an aggressive schedule presented a challenge for testing of the complex MLAS system. The successful pad abort flight demonstration test was attributed to the project s systems engineering and integration process, which included: a concise definition of, and an adherence to, flight test objectives; a solid operational concept; well defined performance requirements, and a test program tailored to reducing the highest flight test risks. The testing ranged from wind tunnel validation of computational fluid dynamic simulations to component ground tests of the highest risk subsystems. This paper provides an overview of the testing/risk management approach and methodologies used to understand and reduce the areas of highest risk - resulting in a successful flight demonstration test.

    These kickers will be used to make fast dipoles and quadrupoles which are driven by sharp risetime pulsers to provide precision beam manipulations for high current kA electron beams. This technology will be used on the 2nd axis of the DARHT linac at LANL. It will be used to provide 4 micropulses of pulse width 20 to 120 nsec. selected from a 2 {micro}sec., 2kA, 20MeV macropulse. The fast pulsers will have amplitude modulation capability to compensate for beam-induced steering effects and other slow beam centroid motion to within the bandwidth of the kicker system. Scaling laws derived from theory will be presented along with extensive experimental data obtained on the test bed ETA-II.

    The majority of abortions in Colombia continue to take place outside the formal health system under a range of conditions, with the majority of women obtaining misoprostol from a thriving black market for the drug and self-administering the medication. We conducted a cost analysis to compare the costs to the health system of three approaches to the provision of abortion care in Colombia: post-abortion care for complications of unsafe abortions, and for legal abortions in a health facility, misoprostol-only medical abortion and vacuum aspiration abortion. Hospital billing records from three institutions, two large maternity hospitals and one specialist reproductive health clinic, were analysed for procedure and complication rates, and costs by diagnosis. The majority of visits (94%) were to the two hospitals for post-abortion care; the other 6% were for legal abortions. Only one minor complication was found among the women having legal abortions, a complication rate of less than 1%. Among the women presenting for post-abortion care, 5% had complications during their treatment, mainly from infection or haemorrhage. Legal abortions were associated not only with far fewer complications for women, but also lower costs for the health system than for post-abortion care. We calculated based on our findings that for every 1,000 women receiving post-abortion care instead of a legal abortion within the health system, 16 women experienced avoidable complications, and the health system spent US $48,000 managing them. Increasing women's access to safe abortion care would not only reduce complications for women, but would also be a cost-saving strategy for the health system. PMID:25702076

    2015-01-01

    This paper will present an overview of the flight test objectives and performance of the Orion Launch Abort System during Exploration Flight Test-1. Exploration Flight Test-1, the first flight test of the Orion spacecraft, was managed and led by the Orion prime contractor, Lockheed Martin, and launched atop a United Launch Alliance Delta IV Heavy rocket. This flight test was a two-orbit, high-apogee, high-energy entry, low-inclination test mission used to validate and test systems critical to crew safety. This test included the first flight test of the Launch Abort System preforming Orion nominal flight mission critical objectives. NASA is currently designing and testing the Orion Multi-Purpose Crew Vehicle (MPCV). Orion will serve as NASA's new exploration vehicle to carry astronauts to deep space destinations and safely return them to earth. The Orion spacecraft is composed of four main elements: the Launch Abort System, the Crew Module, the Service Module, and the Spacecraft Adapter (Fig. 1). The Launch Abort System (LAS) provides two functions; during nominal launches, the LAS provides protection for the Crew Module from atmospheric loads and heating during first stage flight and during emergencies provides a reliable abort capability for aborts that occur within the atmosphere. The Orion Launch Abort System (LAS) consists of an Abort Motor to provide the abort separation from the Launch Vehicle, an Attitude Control Motor to provide attitude and rate control, and a Jettison Motor for crew module to LAS separation (Fig. 2). The jettison motor is used during a nominal launch to separate the LAS from the Launch Vehicle (LV) early in the flight of the second stage when it is no longer needed for aborts and at the end of an LAS abort sequence to enable deployment of the crew module's Landing Recovery System. The LAS also provides a Boost Protective Cover fairing that shields the crew module from debris and the aero-thermal environment during ascent. Although the

    This paper describes how the Abort Motor thrust profile has been tailored and how optimizing the Concept of Operations on the Launch Abort System (LAS) of the Orion Crew Exploration Vehicle (CEV) aides in getting the crew safely away from a failed Crew Launch Vehicle (CLV). Unlike the passive nature of the Apollo system, the Orion Launch Abort Vehicle will be actively controlled, giving the program a more robust abort system with a higher probability of crew survival for an abort at all points throughout the CLV trajectory. By optimizing the concept of operations and thrust profile the Orion program will be able to take full advantage of the active Orion LAS. Discussion will involve an overview of the development of the abort motor thrust profile and the current abort concept of operations as well as their effects on the performance of LAS aborts. Pad Abort (for performance) and Maximum Drag (for separation from the Launch Vehicle) are the two points that dictate the required thrust and shape of the thrust profile. The results in this paper show that 95% success of all performance requirements is not currently met for Pad Abort. Future improvements to the current parachute sequence and other potential changes will mitigate the current problems, and meet abort performance requirements.

The environment, built using a commercial dynamic systems design package, includes use of an open-source configuration control software tool and a collaborative wiki to coordinate between the simulation developers, control law developers and users. A method for switching between multiple candidate control laws and vehicle configurations is described. Aerodynamic models, especially in a development program, change rapidly, so a means for automating the implementation of new aerodynamic models is described.

    Aborts during the critical ascent flight phase require the design and operation of Orion Crew Exploration Vehicle (CEV) systems to escape from the Crew Launch Vehicle (CLV) and return the crew safely to the Earth. To accomplish this requirement of continuous abort coverage, CEV ascent abort modes are being designed and analyzed to accommodate the velocity, altitude, atmospheric, and vehicle configuration changes that occur during ascent. Aborts from the launch pad to early in the flight of the CLV second stage are performed using the Launch Abort System (LAS). During this type of abort, the LAS Abort Motor is used to pull the Crew Module (CM) safely away from the CLV and Service Module (SM). LAS abort guidance and control studies and design trades are being conducted so that more informed decisions can be made regarding the vehicle abort requirements, design, and operation. This paper presents an overview of the Orion CEV, an overview of the LAS ascent abort mode, and a summary of key LAS abort analysis methods and results.

    2004-07-05

    Since the RHIC Au-Au run in the year 2001 the 200 MHz cavity system was used at storage and a 28 MHz system during injection and acceleration. The rebucketing procedure potentially causes a higher debunching rate of heavy ion beams in addition to amplifying debunching due to other mechanisms. At the end of a four hour store, debunched beam can easily account for more than 50% of the total beam intensity. This effect is even stronger with the achieved high intensities of the RHIC Au-Au run in 2004. A beam abort at the presence of a lot of debunched beam bears the risk of magnet quenching and experimental detector damage due to uncontrolled beam losses. Thus it is desirable to avoid any accumulation of debunched beam from the beginning of each store, in particular to anticipate cases of unscheduled beam aborts due to a system failure. A combination of a fast transverse kickers and the new 2-stage copper collimator system are used to clean the abort gap continuously throughout the store with a repetition rate of 1 Hz. This report gives. an overview of the new gap cleaning procedure and the achieved performance.

    The NASA Engineering and Safety Center (NESC) is an independent engineering analysis and test organization providing support across the range of NASA programs. In 2007 NASA was developing the launch escape system for the Orion spacecraft that was evolved from the traditional tower-configuration escape systems used for the historic Mercury and Apollo spacecraft. The NESC was tasked, as a programmatic risk-reduction effort to develop and flight test an alternative to the Orion baseline escape system concept. This project became known as the Max Launch Abort System (MLAS), named in honor of Maxime Faget, the developer of the original Mercury escape system. Over the course of approximately two years the NESC performed conceptual and tradeoff analyses, designed and built full-scale flight test hardware, and conducted a flight test demonstration in July 2009. Since the flight test, the NESC has continued to further develop and refine the MLAS concept.

    The single-bunch kicker magnet is powered by a capacitor discharge pulser. The ferrite-core magnet is used to kick out one of twelve proton bunches circulating in the AGS (Alternating Gradient Synchrotron) into the experimental area. The magnet current pulse has a half-sinusoid shape, with a peak current of 2800 A. The pulse current rises and falls to zero, with minimum undershoot, in 410 nsec to minimize effects on adjacent bunches. The magnet inductance is 1.0 ..mu..Hy. The pulser is mounted on the kicker magnet in the AGS ring, and is exposed to ionizing radiation. The HVDC power supply, controls, monitoring, and auxiliary circuits are housed approximately 300 feet away external to the ring. A two-gap thyratron is used to discharge the energy storage capacitor. Two hydrogen diodes are series connected to function as an inverse diode.

    The Linac Coherent Light Source (LCLS), a pioneer hard x-ray free electron laser is currently under construction at the Stanford Linear Accelerator Center. It is expected that by 2009 LCLS will deliver laser pulses of unprecedented brightness and short length, which will be used in several forefront research applications. This ambitious project encompasses major design challenges to the radiation protection like the numerous sources and the number of surveyed objects. In order to sort those, the showers from various loss sources have been tracked along a detailed model covering 1/2 mile of LCLS accelerator by means of the Monte Carlo intra nuclear cascade codes FLUKA and MARS15. This article covers the FLUKA studies of heat load; prompt and residual dose and environmental impact for the LCLS beam abort system.

    1996-01-01

    This document compares the legal aspects of induced abortion in the US and Germany with a focus on how each country treats minors who wish to undergo abortion. After a short introduction, the second section describes the legal approach to abortion in the US where women (including minors) have an implicitly recognized constitutional right to abortion until compelling state interest intervenes at a point where the unborn child would be viable outside of the womb. States, however, may permit parents to participate in their daughter's abortion decisions as long as a "judicial bypass procedure" exists to protect the minor's rights. Section 3 describes the situation in Germany, where no constitutional right to abortion exists and where the fetus is protected by the constitution. A minor's right to abortion is determined by the provisions governing whether or not an abortion can be performed, by age limitations, and by the custody rights of the parents. Relevant decisions of the Federal Constitutional Court in 1975 and 1993 are reviewed to show that women have a duty to carry a pregnancy to term unless the woman requests the abortion within 12 weeks of conception and submits to counseling which seeks to protect the fetus (such an abortion would be illegal but immune from prosecution). German court rulings on the competency of minors to render consent are then noted to show that even minors have ultimate responsibility with regard to abortion. Analysis of the legal situation in Germany continues with a look at the personal custody rights of parents and the limitations on those rights imposed by the constitutional rights of the child, by the child's age, and by the child's self-reliance and capacity to assume responsibility. The conclusion contrasts the US and German legal sources of limitation of parental rights over the decisions of minors and the ways each system determines the competency of a minor to make such a decision.

    In 2007, the NASA Engineering and Safety Center (NESC) initiated the Max Launch Abort System Project to explore crew escape system concepts designed to be fully encapsulated within an aerodynamic fairing and smoothly integrated onto a launch vehicle. One objective of this design was to develop a more compact launch escape vehicle that eliminated the need for an escape tower, as was used in the Mercury and Apollo escape systems and what is planned for the Orion Multi-Purpose Crew Vehicle (MPCV). The benefits for the launch vehicle of eliminating a tower from the escape vehicle design include lower structural weights, reduced bending moments during atmospheric flight, and a decrease in induced aero-acoustic loads. This paper discusses the development of encapsulated, towerless launch escape vehicle concepts, especially as it pertains to the flight performance and systems analysis trade studies conducted to establish mission feasibility and assess system-level performance. Two different towerless escape vehicle designs are discussed in depth: one with allpropulsive control using liquid attitude control thrusters, and a second employing deployable aft swept grid fins to provide passive stability during coast. Simulation results are presented for a range of nominal and off-nominal escape conditions.

    In 2007, the NASA Exploration Systems Mission Directorate (ESMD) chartered the NASA Engineering Safety Center (NESC) to demonstrate an alternate launch abort concept as risk mitigation for the Orion project's baseline "tower" design. On July 8, 2009, a full scale and passively, aerodynamically stabilized MLAS launch abort demonstrator was successfully launched from Wallops Flight Facility following nearly two years of development work on the launch abort concept: from a napkin sketch to a flight demonstration of the full-scale flight test vehicle. The MLAS flight test vehicle was instrumented with a suite of aerodynamic sensors. The purpose was to obtain sufficient data to demonstrate that the vehicle demonstrated the behavior predicted by Computational Fluid Dynamics (CFD) analysis and wind tunnel testing. This paper describes development of the Air Data Boom (ADB) component of the aerodynamic sensor suite.

    In order to mitigate catastrophic failures on future generation space vehicles, engineers at the National Aeronautics and Space Administration have begun to integrate a novel crew abort systems that could pull a crew module away in case of an emergency at the launch pad or during ascent. The Max Launch Abort System (MLAS) is a recent test vehicle that was designed as an alternative to the baseline Orion Launch Abort System (LAS) to demonstrate the performance of a "tower-less" LAS configuration under abort conditions. The MLAS II test vehicle will execute a propulsive coast stabilization maneuver during abort to control the vehicles trajectory and thrust. To accomplish this, the spacecraft will integrate an Attitude Control System (ACS) with eight hypergolic monomethyl hydrazine liquid propulsion engines that are capable of operating in a quick pulsing mode. Two main elements of the ACS include a propellant distribution subsystem and a pressurization subsystem to regulate the flow of pressurized gas to the propellant tanks and the engines. The CAD assembly of the Attitude Control System (ACS) was configured and integrated into the Launch Abort Vehicle (LAV) design. A dynamic random vibration analysis was conducted on the Main Propulsion System (MPS) helium pressurization panels to assess the response of the panel and its components under increased gravitational acceleration loads during flight. The results indicated that the panels fundamental and natural frequencies were farther from the maximum Acceleration Spectral Density (ASD) vibrations which were in the range of 150-300 Hz. These values will direct how the components will be packaged in the vehicle to reduce the effects high gravitational loads.

    Over the last few years, physicists have occasionally observed the presence of noise acting on the RHIC beams leading to emittance growth at high beam energies. While the noise was sporadic in the past, it became persistent during the Run-11 setup period. An investigation diagnosed the source as originating from the RHIC dump kicker system. Once identified the issue was quickly resolved. We report in this paper the investigation result, circuit analysis, measured and simulated waveforms, solutions, and future plans.

    Prenatal mortality is an important cause of production losses in the livestock industry. This study estimates the prevalences of abortion and stillbirth in a beef cattle system and determines the significance of some risk factors, in the tropics of Mexico. Data were obtained from a Zebu cattle herd and their crosses with Bos taurus breeds, in Yucatan, Mexico. The logit of the probability of an abortion or stillbirth was modeled using binary logistic regression. The risk factors tested were: year of abortion (or calving), season of abortion (or calving), parity number and dam breed group. The effect of twins on stillbirth was tested using Fisher exact test. Of the 4175 calvings studied 49 were abortions (1.17%). Significant factors in the logistic regression analysis for abortions were season of abortion and parity number. The risk of abortion was lower in the dry seasons compared to the rainy and windy seasons (P = 0.009). The risk of abortion was higher in second parity cows followed by the third and first parity cows, as compared to older cows (P = 0.015). Of the 4126 births, 87 were stillbirths (2.11%). Significant factors in the logistic regression analysis for stillbirth were year of calving (P = 0.0001) and parity number (P < 0.001). The risk of stillbirth in first parity cows was 2.6 times that of old cows. Of the total births, 15 were twins (0.36%) of which 7 were born dead calves. Herd owners must focus on the significant risk factors under their control to reduce the prevalence of prenatal mortality. PMID:19449114

    A charged-particle beam generates electromagnetic fields which in turn interact with the beam`s surroundings. These interactions can produce fields which act back on the beam itself, or, if the ``surroundings`` are of suitably designed form (e.g., sensing electrodes with electrical connection to the ``outside world``), can provide information on various properties of the beam; such electrodes are generally known as pickups. Similarly, charged- particle beams respond to the presence of externally imposed electromagnetic fields; devices used to generate such fields are generally known as kickers. As we shall show, the behavior of an electrode system when it functions as a pickup is intimately related to its behavior as a kicker. A number of papers on pickup behavior have appeared in recent years in most of which the primary emphasis has been on beam instrumentation; there have also been several workshops on the subject. There have been several papers which have treated both pickup and kicker behavior of a particular electrode system, but this has been done in the context of discussing a specialized application, such as a stochastic cooling system. The approach in the present paper is similar to that of earlier works by one of the authors, which is to provide a unified treatment of pickup and kicker behavior, and, it is hoped, to give the reader an understanding which is both general and fundamental enough to make the above references easily accessible to him. As implied by the revised title, we have done the re-writing with the non-expert in mind. We have made the introduction both lengthier and more detailed, and done the same with much of the explanatory material and discussion.

    High intensity proton particle accelerators that supports several simultaneous physics experiments requires sharing the beam. A bunch by bunch beam chopper system located after the Radio Frequency Quadrupole (RFQ) is required in this case to structure the beam in the proper bunch format required by the several experiments. The unused beam will need to be kicked out of the beam path and is disposed in a beam dumb. In this paper, we report on the RF modeling results of a proposed helical kicker. Two beam kickers constitutes the proposed chopper. The beam sequence is formed by kicking in or out the beam bunches from the streamline. The chopper was developed for Project X Injection Experiment (PXIE).

    In the NSLS2 storage ring, there are four stripline kickers/pickups. Two long striplines with electrode length of 30cm will be used as bunch-by-bunch transverse feedback actuators. Two short stripline kickers/pickups with 15cm length will mainly used for tune measurement excitation or signal pickup for the beam stability monitor. High shunt impedance of the long stripline kickers is demanded to produce 200 {micro}s damping time. Meanwhile the beam impedance should be minimized. The design work for these two types of stripline is discussed in this paper. NSLS2 is a third-generation light source under construction at Brookhaven National Laboratory. The machine will have < 1nm.rad horizontal emittance by using weak dipoles together with damping wigglers. For the storage ring of 792m circumference, geometric impedance, resistive wall impedance and ion effects are expected to be significant. A transverse bunch-by-bunch feedback system has been designed to suppress the coupled bunch instabilities. More information can be found in previous paper.

    This paper presents an overview of the flight test objectives and performance of the Orion Launch Abort System during Exploration Flight Test-1. Exploration Flight Test-1, the first flight test of the Orion spacecraft, was managed and led by the Orion prime contractor, Lockheed Martin, and launched atop a United Launch Alliance Delta IV Heavy rocket. This flight test was a two-orbit, high-apogee, high-energy entry, low-inclination test mission used to validate and test systems critical to crew safety. This test included the first flight test of the Launch Abort System performing Orion nominal flight mission critical objectives. Although the Orion Program has tested a number of the critical systems of the Orion spacecraft on the ground, the launch environment cannot be replicated completely on Earth. Data from this flight will be used to verify the function of the jettison motor to separate the Launch Abort System from the crew module so it can continue on with the mission. Selected Launch Abort System flight test data is presented and discussed in the paper. Through flight test data, Launch Abort System performance trends have been derived that will prove valuable to future flights as well as the manned space program.

    Every year, an estimated 2.0-4.4 million adolescents resort to abortion. In comparison with adults, adolescents are more likely to delay the abortion, resort to unskilled persons to perform it, use dangerous methods and present late when complications arise. Adolescents are also more likely to experience complications. Consequently, adolescents seeking abortion or presenting with complications of abortion should be considered as a medical emergency. Issues requiring special attention in the management of abortion complications in adolescents are identified. Approaches to adolescent abortion should involve all levels of the health care system, as well as the community, and should include not only management of the consequences of unsafe abortion, but also post-abortion contraception and counseling. Prevention of unwanted pregnancy by providing information on sexuality, ensuring that reproductive health services are adolescent-friendly, creating a supportive environment, building young people's social and decision-making skills, and offering counseling in times of crisis are highlighted.

    Conceptual designs of a fail-safe abort system for hydrogen fueled actively cooled high speed aircraft are examined. The fail-safe concept depends on basically three factors: (1) a reliable method of detecting a failure or malfunction in the active cooling system, (2) the optimization of abort trajectories which minimize the descent heat load to the aircraft, and (3) fail-safe thermostructural concepts to minimize both the weight and the maximum temperature the structure will reach during descent. These factors are examined and promising approaches are evaluated based on weight, reliability, ease of manufacture and cost.

    Analysis of abortion in Mexico from a juridical perspective requires recognition that Mexico as a national community participates in a double system of values. Politically it is defined as a liberal, democratic, and secular state, but culturally the Judeo-Christian ideology is dominant in all social strata. This duality complicates all juridical-penal decisions regarding abortion. Public opinion on abortion is influenced on the 1 hand by extremely conservative groups who condemn abortion as homicide, and on the other hand by groups who demand legislative reform in congruence with characteristics that define the state: an attitude of tolerance toward the different ideological-moral positions that coexist in the country. The discussion concerns the rights of women to voluntary maternity, protection of health, and to making their own decisions regarding their bodies vs. the rights of the fetus to life. The type of analysis is not objective, and conclusions depend on the ideology of the analyst. Other elements must be examined for an objective consideration of the social problem of abortion. For example, aspects related to maternal morbidity and mortality and the demographic, economic, and physical and mental health of the population would all seem to support the democratic juridical doctrine that sees the clandestine nature of abortion as the principal problem. It is also observed that the illegality of abortion does not guarantee its elimination. Desperate women will seek abortion under any circumstances. The illegality of abortion also impedes health and educational policies that would lower abortion mortality. There are various problems from a strictly juridical perspective. A correct definition of the term abortion is needed that would coincide with the medical definition. The discussion must be clearly centered on the protected juridical right and the definition of reproductive and health rights and rights to their own bodies of women. The experiences of other

    We describe a very fast counter traveling wave kicker with a full pulse width of about 7 ns. Successful test experiment has been done with hi-tech semiconductor technology FET pulse generator with a MHz- range repetition rates and maximum kick strength of the order of 3 G{center_dot}m. Further. increase of the strength seems to be quite possible with the FET pursers, that makes the kicker to be very useful tool for bunch-by-bunch injection/extraction and other accelerator applications.

    Recent proposed federal legislation banning certain abortion procedures, particularly intact dilatation and extraction, would modify the US Criminal Code such that physicians performing these procedures would be liable for monetary and statutory damages. Clarification of medical procedures is important because some of the procedures used to induce abortion prior to viability are identical or similar to postviability procedures. This article reviews the scientific and medical information on late-term abortion and late-term abortion techniques and includes data on the prevalence of late-term abortion, abortion-related mortality and morbidity rates, and legal issues regarding fetal viability and the balance of maternal and fetal interests. According to enacted American Medical Association (AMA) policy, the use of appropriate medical terminology is critical in defining late-term abortion procedures, particularly intact dilatation and extraction, which is a variant of but distinct from dilatation and evacuation. The AMA recommends that the intact dilatation and extraction procedure not be used unless alternative procedures pose materially greater risk to the woman and that abortions not be performed in the third trimester except in cases of serious fetal anomalies incompatible with life. Major medical societies are urged to collaborate on clinical guidelines on late-term abortion techniques and circumstances that conform to standards of good medical practice. More research on the advantages and disadvantages of specific abortion procedures would help physicians make informed choices about specific abortion procedures. Expanded ongoing data surveillance systems estimating the prevalence of abortion are also needed. PMID:9728645

    The National Aeronautics and Space Administration (NASA) Engineering and Safety Center (NESC) designed, developed and flew the alternative Max Launch Abort System (MLAS) as risk mitigation for the baseline Orion spacecraft launch abort system (LAS) already in development. The NESC was tasked with both formulating a conceptual objective system (OS) design of this alternative MLAS as well as demonstrating this concept with a simulated pad abort flight test. The goal was to obtain sufficient flight test data to assess performance, validate models/tools, and to reduce the design and development risks for a MLAS OS. Less than 2 years after Project start the MLAS simulated pad abort flight test was successfully conducted from Wallops Island on July 8, 2009. The entire flight test duration was 88 seconds during which time multiple staging events were performed and nine separate critically timed parachute deployments occurred as scheduled. Overall, the as-flown flight performance was as predicted prior to launch. This paper provides an overview of the guidance navigation and control (GN&C) technical approaches employed on this rapid prototyping activity. This paper describes the methodology used to design the MLAS flight test vehicle (FTV). Lessons that were learned during this rapid prototyping project are also summarized.

    Past and present efforts by the authors to further understanding of the ceramic matrix composite (CMC) material used in the valve components of the Orion Launch Abort System (LAS) Attitude Control Motor (ACM) will be presented. The LAS is designed to quickly lift the Orion Crew Exploration Vehicle (CEV) away from its launch vehicle in emergency abort scenarios. The ACM is a solid rocket motor which utilizes eight throttleable nozzles to maintain proper orientation of the CEV during abort operations. Launch abort systems have not been available for use by NASA on manned launches since the last Apollo ]Saturn launch in 1975. The CMC material, carbon-carbon/silicon-carbide (C/C-SiC), is manufactured by Fiber Materials, Inc. and consists of a rigid 4-directional carbon-fiber tow weave reinforced with a mixed carbon plus SiC matrix. Several valve and full system (8-valve) static motor tests have been conducted by the motor vendor. The culmination of these tests was the successful flight test of the Orion LAS Pad Abort One (PA ]1) vehicle on May 6, 2010. Due to the fast pace of the LAS development program, NASA Marshall Space Flight Center assisted the LAS community by performing a series of material and component evaluations using fired hardware from valve and full ]system development motor tests, and from the PA-1 flight ACM motor. Information will be presented on the structure of the C/C-SiC material, as well as the efficacy of various non ]destructive evaluation (NDE) techniques, including but not limited to: radiography, computed tomography, nanofocus computed tomography, and X-ray transmission microscopy. Examinations of the microstructure of the material via scanning electron microscopy and energy dispersive spectroscopy will also be discussed. The findings resulting from the subject effort are assisting the LAS Project in risk assessments and in possible modifications to the final ACM operational design.

  16. Optimal return-to-launchsite abort trajectories for an HL-20 Personnel Launch System vehicle

    NASA Astrophysics Data System (ADS)

    Dutton, Kevin E.

    The Personnel Launch System (PLS) being studied by NASA is a system to complement the Space Shuttle and provide alternative access to space. The PLS consists of a manned spacecraft launched by an expendable launch vehicle (ELV). A candidate for the manned spacecraft is the HL-20 lifting body. In the event of an ELV malfunction during the initial portion of the ascent trajectory, the HL-20 will separate from the rocket and perform an unpowered return-to-launchsite (RTLS) abort. This paper describes an investigation of the RTLS abort scenario using optimal control theory. The objective of the abort trajectory is to maximize final altitude at a point near the runway. The assumption is then made that there exists a control history to steer the vehicle to any final altitude lower than the final optimal altitude. With this selection of cost function, and with this assumption, the feasibility of an RTLS abort at different times along the ascent trajectory can be determined. The method of differential inclusions, which allows the determination of optimal states and eliminates the need for determining the optimal controls, is used to determine the optimal trajectories.

    The space transportation system using capsule/rocket configurations such as Apollo and Soyuz are simple compared with Space Shuttle, and have several merits from the viewpoint of reliability. The capsule/rocket system will take over the Space Shuttle, after it retires in 2010. As the Space Shuttle accidents had been caused by several factors, e.g., aerodynamic interaction of shock waves ahead of its wing, advanced abort systems such as LAS (Launch Abort System) are required for the capsule/rocket system. In the present study, as a baseline configuration, a combination of a cone and a cylinder is employed as a CEV (Crew Exploration Vehicle), which consists of a capsule (LAV: Launch Abort Vehicle) and a rocket (SM: Service Module). By changing the relative position of the two components as well as the profile area of the rocket, their effects on the capsule/rocket aerodynamic interaction and characteristics (drag and pitching moment) are experimentally and numerically investigated at a supersonic speed (M∞ = 3.0). It is found from the results that the clearance have little effects on the flow field for the case of the baseline configuration. The capsule always showed a positive drag (CD = 0.34), which means that thrust is required to overcome the drag. Otherwise the capsule will recontact the rocket. However in the case where the rocket contact area is 2.2 times as large as the capsule profile, more favorable effects were obtained. Especially in the case of a certain clearance (h/D = 0.40), the drag coefficient of the capsule is CD = -0.35, which means that the capsule suffers a thrust force from the aerodynamic interaction. Under this condition, if capsule has a pitch angle with 5 degrees instantaneously, then pitching moment coefficient becomes CMp = -0.41 therefore capsule stabilize. However, in the case of a very small clearance (h/D ∝ 0.00), the flow becomes unsteady involving pulsating shock wave, leading to a potentially risky separation of the capsule.

    The fill pattern in proton synchrotrons usually features an empty gap, longer than the abort kicker raise time, for machine protection. This gap is referred to as the "abort gap," and any particles, which may accumulate in it due to injection errors and diffusion between RF buckets, would be lost inside the ring, rather than in the beam dump, during the kicker firing. In large proton rings, due to the high energies involved, it is vital to monitor the build up of charges in the abort gap with a high sensitivity. We present a study of an abort gap monitor based on a photomultiplier with a gated microchannel plate, which would allow for detecting low charge densities by monitoring the synchrotron radiation emitted. We show results of beam test experiments at the Advanced Light Source using a Hamamatsu 5916U MCP-PMT and compare them to the specifications for the Large Hadron Collider.

    This article presents estimates based on the research conducted in 2010 of the cost to the Ugandan health system of providing post-abortion care (PAC), filling a gap in knowledge of the cost of unsafe abortion. Thirty-nine public and private health facilities were sampled representing three levels of health care, and data were collected on drugs, supplies, material, personnel time and out-of-pocket expenses. In addition, direct non-medical costs in the form of overhead and capital costs were also measured. Our results show that the average annual PAC cost per client, across five types of abortion complications, was $131. The total cost of PAC nationally, including direct non-medical costs, was estimated to be $13.9 million per year. Satisfying all demand for PAC would raise the national cost to $20.8 million per year. This shows that PAC consumes a substantial portion of the total expenditure in reproductive health in Uganda. Investing more resources in family planning programmes to prevent unwanted and mistimed pregnancies would help reduce health systems costs. PMID:23274438

    Based on research conducted in 2012, we estimate the cost to the Rwandan health-care system of providing post-abortion care (PAC) due to unsafe abortions, a subject of policy importance not studied before at the national level. Thirty-nine public and private health facilities representing three levels of health care were randomly selected for data collection from key care providers and administrators for all five regions. Using an ingredients approach to costing, data were gathered on drugs, supplies, material, personnel time and hospitalization. Additionally, direct non-medical costs such as overhead and capital costs were also measured. We found that the average annual PAC cost per client, across five types of abortion complications, was $93. The total cost of PAC nationally was estimated to be $1.7 million per year, 49% of which was expended on direct non-medical costs. Satisfying all demands for PAC would raise the national cost to $2.5 million per year. PAC comprises a significant share of total expenditure in reproductive health in Rwanda. Investing more resources in provision of contraceptive services to prevent unwanted or mistimed pregnancies would likely reduce health systems costs. PMID:24548846

    The presence of significant intensities of un-bunched beam is a potentially serious issue in the LHC. Procedures using damper kickers for cleaning both the Abort Gap (AG) and the buckets targeted for injection, are currently in operation at flat bottom. Recent observations of relatively high population of the AG during physics runs brought up the need for AG cleaning during luminosity operation. In this paper the results of experimental studies performed in October 2011 are presented.

    1997-07-01

    The RHIC injection kicker is built as a traveling wave structure in order to assure the required 95 nsec risetime in the deflection strength. The kicker is constructed from 14 cells, each 7.5 cm long, with alternating ferrite and high-permittivity dielectric sections. The cell structure permits an analysis of the electrical properties of the kicker using lumped L, C, and R circuit elements. Their values are obtained directly from impedance measurements of the full-length kicker, the inductance and shunt capacitance values by measuring the input impedance at 1 MHz with the output shorted and open, respectively. A lossy series resonance circuit in each cell is found to reproduce the measured input impedance of the terminated kicker up to {approximately}100 MHz. The validity of the equivalent circuit was confirmed by comparing the measured output current pulse shape time with that computed by the P-Spice program.

    The Spallation Neutron Source (SNS) Accumulator ring extraction kickers [1] consists of 14 modules of windowframe ferrite pulsing magnets with the rise time of about 200 ns. Their contribution to the beam coupling impedances is a serious concern. The kicker impedances, as well as its deflecting magnetic field versus time, are studied using detailed 3-D MAFIA modeling. Various design options, external circuit resistances, and a range of ferrite permeabilities are explored. A kicker module with wide conductor windings around the ferrite behind the kicker current sheet suggests a significant reduction of the kicker transverse and longitudinal coupling impedances. This design provides a good extraction field performance, as demonstrated by electromagnetic simulations. Results of measurements for a small model are also presented.

    The kink instability is one of the major beam dynamics issues of the linac-ring based electron ion collider. This head-tail type instability arises from the oscillation of the electron beam inside the opposing ion beam. It must be suppressed to achieve the desired luminosity. There are various ways to suppress the instability, such as tuning the chromaticity in the ion ring or by a dedicated feedback system of the electron beam position at IP, etc. However, each method has its own limitation. In this paper, we will discuss an alternative opportunity of suppressing the kink instability of the proposed eRHIC at BNL using the existing pickup-kicker system of the stochastic cooling system in RHIC.

    The current electron cooler design for the proposed Medium Energy Electron-Ion collider (MEIC) at Jefferson Lab utilizes a circulator ring for reuse of the cooling electron bunch up to 100 times to cool the ion beams. This cooler requires a fast kicker system for injecting and extracting individual bunches in the circulator ring. Such a kicker must work at a high repetition rate, up to 7.5 to 75 MHz depending on the number of turns in the recirculator ring. It also must have a very short rise and fall time (of order of 1 ns) such that it will kick an individual bunch without disturbing the others in the ring. Both requirements are orders of magnitude beyond the present state-of-the-art as well as the goals of other on-going kicker R&D programs such as that for the ILC damping rings. In this paper we report a scheme of creating this fast, high repetition rate kicker by combining RF waveforms at multiple frequencies to create a kicker waveform that will, for example, kick every eleventh bunch while leaving the other ten unperturbed. We also present a possible implementation of this scheme as well as discuss its limitations.

    The design of the RHIC injection systems anticipated the possibility of filling and operating the rings with a 120 bunch pattern, corresponding to 110 bunches after allowing for the abort gap. Beam measurements during the 2002 run confirmed the possibility, although at the expense of severe transverse emittance growth and thus not on an operational basis. An improvement program was initiated with the goal of reducing the kicker rise time from 110 to {approx}95 ns and of minimizing pulse timing jitter and drift. The major components of the injection system are 4 kicker magnets and Blmlein pulsers using thyratron switches. The kicker terminating resistor and operating voltage was increased to reduce the rise time. Timing has been stabilized by using commercial trigger units and extremely stable dc supplies for the thyratron reservoir. A fiber optical connection between control room and the thyratron trigger unit has been provided, thereby allowing the operator to adjust timing individually for each kicker unit. The changes were successfully implemented for use in the RHIC operation.

  11. Addressing barriers to safe abortion.

    2013-05-01

    The latest World Health Organization data estimate that the total number of unsafe abortions globally has increased to 21.6 million in 2008. There is increasing recognition by the international community of the importance of the contribution of unsafe abortion to maternal mortality. However, the barriers to delivery of safe abortion services are many. In 68 countries, home to 26% of the world's population, abortion is prohibited altogether or only permitted to save a woman's life. Even in countries with more liberal abortion legal frameworks, additional social, economic, and health systems barriers and the stigma surrounding abortion prevent adequate access to safe abortion services and postabortion care. While much has been achieved to reduce the barriers to comprehensive abortion care, much remains to be done. Only through the concerted action of public, private, and civil society partners can we ensure that women have access to services that are safe, affordable, confidential, and stigma free.

  12. Psychosocial aspects of abortion

    Illsley, Raymond; Hall, Marion H.

    1976-01-01

    The literature on psychosocial aspects of abortion is confusing. Individual publications must be interpreted in the context of cultural, religious, and legal constraints obtaining in a particular society at a given time, with due attention to the status and availability of alternatives to abortion that might be chosen by a woman with an “unwanted” pregnancy. A review of the literature shows that, where careful pre- and post-abortion assessments are made, the evidence is that psychological benefit commonly results, and serious adverse emotional sequelae are rare. The outcome of refused abortion seems less satisfactory, with regrets and distress frequently occurring. Research on the administration of abortion services suggests that counselling is often of value, that distress is frequently caused by delays in deciding upon and in carrying out abortions, and by unsympathetic attitudes of service providers. The phenomenon of repeated abortion seeking should be seen in the context of the availability and cost of contraception and sterilization. The place of sterilization with abortion requires careful study. A recommendation is made for observational descriptive research on populations of women with potentially unwanted pregnancies in different cultures, with comparisons of management systems and an evaluation of their impact on service users.

    The Large Hadron Collider (LHC), presently under construction at CERN, requires monitoring the parasitic charge in the 3.3ms long gap in the machine fill structure. This gap, referred to as the abort gap, corresponds to the raise time of the abort kickers magnets. Any circulating particle present in the abort gap at the time of the kickers firing is lost inside the ring, rather than in the beam dump, and can potentially damage a number of the LHC components. CERN specifications indicate a linear density of 6 x 106 protons over a 100 ns interval as the maximum charge safely allowed to accumulate in the abort gap at 7 TeV. We present a study of an abort gap monitor, based on a photomultiplier tube with a gated microchannel plate, which would allow for detecting such low charge densities by monitoring the synchrotron radiation emitted in the dedicated diagnostics port. We show results of beam test experiments at the Advanced Light Source (ALS) using a Hamamatsu 5961U MCP-PMT, which indicate that such an instrument has the required sensitivity to meet LHC specifications.

    A study was conducted to determine the quality of thermodynamic and wind data measured by or derived from the Transatlantic Abort Landing (TAL) Atmospheric Sounding System (TASS). The system has Global Positioning System (GPS) tracking capability and includes a helium-filled latex balloon that carries an instrument package (sonde) and various ground equipment that receives and processes the data from the sonde. TASS is used to provide vertical profiles of thermodynamic and low-resolution wind data in support of Shuttle abort landing operations at TAL sites. TASS uses GPS to determine height, wind speed, and wind direction. The TASS sonde has sensors that directly measure air temperature and relative humidity. These are then used to derive air pressure and density. Test flights were conducted where a TASS sonde and a reference sonde were attached to the same balloon and the two profiles were compared.

    The Orion Pad Abort Test 1 was conducted at the US Army White Sands Missile range in May 2010. The capsule was successfully recovered using the original design for the parachute recovery system, referred to as the CEV Parachute Assembly System (CPAS). The CPAS was designed to a set of requirements identified prior to the development of the PA-1 test; these requirements were not entirely consistent with the design of the PA-1 test. This presentation will describe the original CPAS design, how the system was modified to accommodate the PA-1 requirements, and what special analysis had to be performed to demonstrate positive margins for the CPAS. The presentation will also discuss the post test analysis and how it compares to the models that were used to design the system.

    The personnel launch system (PLS) being studied by NASA is a system to complement the space shuttle and provide alternative access to space. The PLS consists of a manned spacecraft launched by an expendable launch vehicle (ELV). A candidate for the manned spacecraft is the HL-20 lifting body. In the event of an ELV malfunction during the initial portion of the ascent trajectory, the HL-20 will separate from the rocket and perform an unpowered return to launch site (RTLS) abort. This work details an investigation, using optimal control theory, of the RTLS abort scenario. The objective of the optimization was to maximize final altitude. With final altitude as the cost function, the feasibility of an RTLS abort at different times during the ascent was determined. The method of differential inclusions was used to determine the optimal state trajectories, and the optimal controls were then calculated from the optimal states and state rates.

    The National Aeronautics and Space Administration (NASA) Engineering and Safety Center was chartered to develop an alternate launch abort system (LAS) as risk mitigation for the Orion Project. Its successful flight test provided data for the design of future LAS vehicles. Design of the flight test vehicle (FTV) and pad abort trajectory relied heavily on modeling and simulation including computational fluid dynamics for vehicle aero modeling, 6-degree-of-freedom kinematics models for flight trajectory modeling, and 3-degree-of-freedom kinematics models for parachute force modeling. This paper highlights the simulation techniques and the interaction between the aerodynamics, flight mechanics, and aerodynamic decelerator disciplines during development of the Max Launch Abort System FTV.

    The Landing Parachute Demonstrator (LPD) was conceived as a low-cost, rapidly-developed means of providing soft landing for the Max Launch Abort System (MLAS) crew module (CM). Its experimental main parachute cluster deployment technique and off-the-shelf hardware necessitated a full-scale drop test prior to the MLAS mission in order to reduce overall mission risk. This test was successfully conducted at Wallops Flight Facility on March 6, 2009, with all vehicle and parachute systems functioning as planned. The results of the drop test successfully qualified the LPD system for the MLAS flight test. This document captures the design, concept of operations and results of the drop test.

  1. Why do farmers and veterinarians not report all bovine abortions, as requested by the clinical brucellosis surveillance system in France?

    PubMed Central

    2014-01-01

    Background Since 2005, France has been officially free of brucellosis, an infectious disease that causes abortion in cattle and can be transmitted from cattle to humans. Recent animal and human cases have drawn attention to the need to prevent infection of humans and animals from any primary outbreaks. In order to detect any new outbreaks as soon as possible, a clinical surveillance system requires farmers and veterinarians to report each abortion and to test the aborting cow for brucellosis. However, under-reporting limits the sensitivity of this system. Our objective was to identify the barriers and motivations influencing field actors in their decision to report or not to report bovine abortions. We used a qualitative approach with semi-structured interviews of 12 cattle farmers and their eight veterinarians. Results Our analysis showed that four main themes influence the decision-making process of farmers and veterinarians: 1) the perceived risk of brucellosis and other abortive diseases; 2) the definition of a suspected case of brucellosis and other abortive diseases adopted by field actors, which is less sensitive than the mandatory definition; 3) the cost-benefit analysis conducted by actors, taking into account regulatory and health aspects, economic and financial losses, technical and practical factors; 4) the level of cooperation within the socio-technical network. We discussed how early detection may be improved by revising the definition of abortion, extending the time frame for notification and generalising the differential diagnosis of the causes of abortion. Conclusions In contrast to quantitative approaches, qualitative studies can identify the factors (including unknown factors) influencing the decision-making process of field actors and reveal why they take those factors into consideration. Our qualitative study sheds light on the factors underlying the poor sensitivity of clinical brucellosis surveillance system for cattle in France, and suggests

    The bovine brucellosis clinical surveillance system implemented in France aims to detect early any case of bovine brucellosis, a disease of which the country has been declared free since 2005. It relies on the mandatory notification of every bovine abortion. Following the spread of the Schmallenberg virus (SBV) in France in 2012 and 2013, and the implementation in 2012 of a clinical surveillance programme of Q fever based on abortion notifications in ten pilot départements, our objective was to study whether these two events influenced the brucellosis clinical surveillance system. The proportion of notifying farmers was analyzed over each semester from June 1, 2009 to June 30, 2013 according to the size and production type of herds, SBV status of départements and the implementation of the Q fever surveillance. Our analysis showed a slight increase in the proportion of notifying farmers as départements became infected by SBV, and after the implementation of Q fever surveillance (during the first semester of 2013). These variations might be explained by an increase in abortion occurrence (congenital deformities in newborns, due to SBV) and/or by an increase in farmers' and veterinarians' awareness (due to the spread of SBV and the implementation of the Q fever surveillance). These results highlight the difficulties in interpreting variations in the proportion of notifying farmers as a consequence of an increase in abortion occurrence. As bovine abortion surveillance can play an important role in the early warning for several diseases, there is a need to explore other ways to monitor abortions in cattle, such as syndromic surveillance using the dates of artificial insemination or calving data.

    One of the primary design drivers for NASA's Crew Exploration Vehicle (CEV) is to ensure crew safety. Aborts during the critical ascent flight phase require the design and operation of CEV systems to escape from the Crew Launch Vehicle and return the crew safely to the Earth. To accomplish this requirement of continuous abort coverage, CEV ascent abort modes are being designed and analyzed to accommodate the velocity, altitude, atmospheric, and vehicle configuration changes that occur during ascent. The analysis involves an evaluation of the feasibility and survivability of each abort mode and an assessment of the abort mode coverage. These studies and design trades are being conducted so that more informed decisions can be made regarding the vehicle abort requirements, design, and operation. This paper presents an overview of the CEV, driving requirements for abort scenarios, and an overview of current ascent abort modes. Example analysis results are then discussed. Finally, future areas for abort analysis are addressed.

    An ultrafast kicker system is being developed for the energy recovery linac (ERL) based electron circulator cooler ring (CCR) in the proposed Jefferson Lab Electron Ion Collider (JLEIC, previously named MEIC). In the CCR, the injected electron bunches can be recirculated while performing ion cooling for 10-30 turns before the extraction, thus reducing the recirculation beam current in the ERL to 1 /10 -1 /30 (150 mA -50 mA ) of the cooling beam current (up to 1.5 A). Assuming a bunch repetition rate of 476.3 MHz and a recirculating factor of 10 in the CCR, the kicker is required to operate at a pulse repetition rate of 47.63 MHz with pulse width of around 2 ns, so that only every 10th bunch in the CCR will experience a transverse kick while the rest of the bunches will not be disturbed. Such a kicker pulse can be synthesized by ten harmonic modes of the 47.63 MHz kicker pulse repetition frequency, using up to four quarter wavelength resonator (QWR) based deflecting cavities. In this paper, several methods to synthesize such a kicker waveform will be discussed and a comparison of their beam dynamics performance is made using ELEGANT. Four QWR cavities are envisaged with high transverse shunt impedance requiring less than 100 W of total rf power for a Flat-Top kick pulse. Multipole fields due to the asymmetry of this type of cavity are analyzed. The transverse emittance growth due to the sextupole component is simulated in ELEGANT. Off-axis injection and extraction issues and beam optics using a multicavity kick-drift scheme will also be discussed.

    This paper describes a study that was conducted to determine the quality of thermodynamic and wind data measured by the Space Shuttle Transatlantic Abort Landing (TAL) Atmospheric Sounding System (TASS). The system has Global Positioning System (GPS) tracking capability and provides profiles of atmospheric parameters such as temperature, relative humidity, and wind in support of potential emergency Space Shuttle landings at TAL sites. Ten comparison flights between the Low-Resolution Flight Element (LRFE) of the Automated Meteorological Profiling System (AMPS) and TASS were conducted at the Eastern Test Range (ETR) in early 2002. Initial results indicated that wind, temperature, and relative humidity compared well. However, incorrect GPS settings in the TASS software were resulting in altitude differences of about 60 to 70 m (approximately 200 to 230 ft) and air pressure differences of approximately 4 hectoPascals (hPa). TASS software updates to correct altitude data were completed in early 2003. Subsequent testing showed that altitude and air pressure differences were generally less than 5 m and 1 hPa, respectively.

    Fast transmission-line kickers contain no ferrite and consist of two long metallic parallel plates supported by insulators inside a beam pipe. A beam is deflected by both the electric and magnetic fields of a TEM wave created by a pulse propagating along the strips in the direction opposite to the beam. Computations of the beam coupling impedances for such structures are difficult because of their length. In the paper, the beam coupling impedances of transmission-line kickers are calculated by combining analytical and numerical methods: the wake potentials computed in short models are extended analytically to obtain the wakes for the long kickers, and then the corresponding beam impedances are derived. At very low frequencies the results are compared with simple analytical expressions for the coupling impedances of striplines in beam position monitors.

  10. Abortion ethics.

    Nurses have opinions about abortion, but because they are health professionals and their opinions are sought as such, they are obligated to understand why they hold certain views. Nurses need to be clear about why they believe as they do, and they must arrive at a point of view in a rational and logical manner. To assist nurses in this task, the ethical issues surrounding abortion are enumerated and clarified. To do this, some of the philosophic and historic approaches to abortion and how a position can be logically argued are examined. At the outset some emotion-laden terms are defined. Abortion is defined as the expulsion of a fetus from the uterus before 28 weeks' gestation, the arbitrarily established time of viability. This discussion is concerned only with induced abortion. Since the beginning of recorded history women have chosen to have abortions. Early Jews and Christians forbade abortion on practical and religious grounds. A human life was viewed as valuable, and there was also the practical consideration of the addition of another person to the population, i.e., more brute strength to do the necessary physical work, defend against enemies, and ensure the continuation of the people. These kinds of pragmatic reasons favoring or opposing abortion have little to do with the Western concept of abortion in genaeral and what is going on in the U.S. today in particular. Discussion of the ethics of abortion must rest on 1 or more of several foundations: whether or not the fetus is a human being; the rights of the pregnant woman as opposed to those of the fetus, and circumstances of horror and hardship that might surround a pregnancy. Viability is relative. Because viability is not a specific descriptive entity, value judgments become part of the determination, both of viability and the actions that might be taken based on that determination. The fetus does not become a full human being at viability. That occurs only at conception or birth, depending on one's view

    Spontaneous abortion in early pregnancy due to unknown reasons is a common problem. The excess complement activation and consequent placental inflammation and anti-angiogenic milieu is emerging as an important associated factor in many pregnancy-related complications. In the present study we sought to examine the expression of complement inhibitory proteins at the feto-maternal interface and levels of complement split products in the circulation to understand their role in spontaneous abortion. Consenting pregnant women who either underwent elective abortion due to non-clinical reasons (n = 13) or suffered miscarriage (n = 14) were recruited for the study. Systemic levels of complement factors C3a and C5a were measured by enzyme-linked immunosorbent assay (ELISA). Plasma C5 and C3 protein levels were examined by Western blot. Expressions of complement regulatory proteins such as CD46 and CD55 in the decidua were investigated by quantitative polymerase chain reaction (PCR) and Western blot. The median of plasma C3a level was 82·83 ng/ml and 66·17 ng/ml in elective and spontaneous abortion patients, respectively. Medians of plasma C5a levels in elective and spontaneous abortion patients were 0·96 ng/ml and 1·14 ng/ml, respectively. Only plasma C5a levels but not C3a levels showed significant elevation in spontaneous abortion patients compared to elective abortion patients. Further, there was a threefold decrease in the mRNA expressions of complement inhibitory proteins CD46 and CD55 in the decidua obtained from spontaneous abortion patients compared to that of elective abortion patients. These data suggested that dysregulated complement cascade may be associated with spontaneous abortion.

    The stochastic cooling system in the Recycler ring at Fermilab required the addition of a 0.5-1 GHz cooling system. This requirement dictated the design of a new antenna for this band of the system. The design problem is defined, method of design is illustrated, and the measurement data are reported. The Recycler is a storage ring comprised of mostly permanent magnets located in the tunnel of the Main Injector at Fermilab. The goal for the construction of the Recycler is to collect and store unused antiprotons from collisions in the Tevatron for use in future collisions in the Tevatron. It will both stochastically and electron cool these unused antiprotons before another collision experiment is possible in the Tevatron. By reusing the antiprotons the luminosity of the experiment can be increased faster. The Recycler will use three bands for its stochastic cooling system. It will reuse the existing designs from the Antiproton Source for the 1-2 GHz and 2-4 GHz systems, and it requires a new design for an additional lower frequency band for the 0.5-1 GHz system. Since the existing designs were fabricated using a microstrip topology it was desired that the new design use a similar topology so that the vacuum tank designs and supporting hardware be identical for all three bands. A primary difference between the design of the pickups/kickers of the Antiproton Source and the Recycler is a different aperture in the machine itself. The Recycler has a bigger aperture and consequently reusing the designs for the existing Antiproton Source pickups/kickers is not electrically optimal but is cost efficient. Measurements will be shown later in this paper for the design of the 0.5-1 GHz system showing the effect of the aperture on the antenna performance. A mockup of the Recycler tank was manufactured for designing and testing the 0.5-1 GHz pickups/kickers. The design procedure was an iterative process and required both a constant dialogue and also a strong relationship with a

    The purpose of NASA's Constellation project is to create the new generation of spacecraft for human flight to the International Space Station in low-earth orbit, the lunar surface, as well as for use in future deep-space exploration. One portion of the Constellation program was the development of the Orion crew exploration vehicle (CEV) to be used in spaceflight. The Orion spacecraft consists of a crew module, service module, space adapter and launch abort system. The crew module was designed to hold as many as six crew members. The Orion crew exploration vehicle is similar in design to the Apollo space capsules, although larger and more massive. The Flight Test Office is the responsible flight test organization for the launch abort system on the Orion crew exploration vehicle. The Flight Test Office originally proposed six tests that would demonstrate the use of the launch abort system. These flight tests were to be performed at the White Sands Missile Range in New Mexico and were similar in nature to the Apollo Little Joe II tests performed in the 1960s. The first flight test of the launch abort system was a pad abort (PA-1), that took place on 6 May 2010 at the White Sands Missile Range in New Mexico. Primary flight test objectives were to demonstrate the capability of the launch abort system to propel the crew module a safe distance away from a launch vehicle during a pad abort, to demonstrate the stability and control characteristics of the vehicle, and to determine the performance of the motors contained within the launch abort system. The focus of the PA-1 flight test was engineering development and data acquisition, not certification. In this presentation, a high level overview of the PA-1 vehicle is given, along with an overview of the Mobile Operations Facility and information on the White Sands tracking sites for radar & optics. Several lessons learned are presented, including detailed information on the lessons learned in the development of wind

    Two-stage winged space access vehicles consisting of a carrier stage with airbreathing turbo/ram jet engines and a rocket propelled orbital stage which may significantly reduce space transport costs and have additional advantages offer a great potential for mission safety improvements. Formulating the nominal mission and abort scenarios caused by engine malfunctions as an optimal control problem allows full exploitation of safety capabilities. The shaping of the nominal mission has a significant impact on the prospective safety. For this purpose, most relevant mission aborts are considered together with the nominal mission, treating them as an optimization problem of branched trajectories where the branching point is not fixed. The applied procedure yields a safety improved nominal trajectory, showing the feasibility of the included mission aborts with minimum payload penalty. The other mission aborts can be separately treated, with the initial condition given by the state of the nominal trajectory at the time when a failure occurs. A mission abort plan is set up, covering all emergency scenarios. PMID:16480117

    In 2007, the NASA Exploration Systems Mission Directorate (ESMD) chartered the NASA Engineering Safety Center (NESC) to demonstrate an alternate launch abort concept as risk mitigation for the Orion project's baseline "tower" design. On July 8, 2009, a full scale, passive aerodynamically stabilized Max Launch Abort System (MLAS) pad abort demonstrator was successfully launched from NASA Goddard Space Flight Center's Wallops Flight Facility. Aerodynamic close-outs were required to cover openings on the MLAS fairing to prevent aerodynamic flow-through and to maintain the MLAS OML surface shape. Two-ply duct tape covers were designed to meet these needs. The duct tape used was a high strength fiber reinforced duct tape with a rubberized adhesive that demonstrated 4.6 lb/in adhesion strength to the unpainted fiberglass fairing. Adhesion strength was observed to increase as a function of time. The covers were analyzed and experimentally tested to demonstrate their ability to maintain integrity under anticipated vehicle ascent pressure loads and to not impede firing of the drogue chute mortars. Testing included vacuum testing and a mortar fire test. Tape covers were layed-up on thin Teflon sheets to facilitate installation on the vehicle. Custom cut foam insulation board was used to fill mortar hole and separation joint cavities and provide support to the applied tape covers. Flight test results showed that the tape covers remained adhered during flight.

  18. COMPENSATION OF FAST KICKER ROLLS WITH SKEW QUADRUPOLES

    SciTech Connect

    Pinayev, I.

    2011-03-28

    The development of the third generation light sources lead to the implementation of the top-up operation, when injection occurs while users collect data. The beam excursions due to the non-closure of the injection bump can spoil the data and need to be suppressed. In the horizontal plane compensation can be achieved by adjusting timing and kick amplitudes. The rolls of the kicker magnets create non-closure in the vertical plane and usually there is no means for correction. In the paper we describe proposed compensation scheme utilizing two skew quadrupoles placed inside the injection bump. The third generation light sources implement top-up operation firstly introduced at Advanced Photon Source. In this mode the circulating beam current is supported near constant by frequent injection of small charge, while photon beam is delivered for users. The beam perturbations caused by the mismatched injection bump can provide undesired noise in the user data. Usually the injection trigger is distributed to the users end stations so that those affected would be able to blank data acquisition. Nevertheless, as good operational practice such transients should be suppressed as much as possible. In the horizontal plane (which is commonly used for injection) one can adjust individual kicker strength as well as trigger delay while observing motion of the stored beam centroid. In the vertical plane such means are unavailable in the most cases. The possible solutions include dedicated weak vertical kickers and motorized adjustment of the roll angle of the injection kickers. Both abovementioned approaches are expensive and can significantly deteriorate reliability. We suggest two employ two skew quadrupoles (to correct both angle and position) placed inside the injection bump. In this case the beam position itself serves as measure of the kicker strength (assuming that kickers are well matched) and vertical kicks from the skew quadrupoles will be self synchronized with injection bump

    The Attitude Control Motor (ACM) is being developed for use in the Launch Abort System (LAS) of NASA's Ares I launch vehicle. The ACM consists of a small solid rocket motor and eight actuated pintle valves that directionally allocate.thrust_- 1t.has-been- predicted-that significant unsteady. pressure.fluctuations.will.exist. inside the-valves during operation. The dominant frequencies of these oscillations correspond to the lowest several acoustic natural frequencies of the individual valves. An acoustic finite element model of the fluid volume inside the valve has been critical to the prediction of these frequencies and their associated mode shapes. This work describes an effort to experimentally validate the acoustic finite model of the valve with an acoustic modal test. The modal test involved instrumenting a flight-like valve with six microphones and then exciting the enclosed air with a loudspeaker. The loudspeaker was configured to deliver broadband noise at relatively high sound pressure levels. The aquired microphone signals were post-processed and compared to results generated from the acoustic finite element model. Initial comparisons between the test data and the model results revealed that additional model refinement was necessary. Specifically, the model was updated to implement a complex impedance boundary condition at the entrance to the valve supply tube. This boundary condition models the frequency-dependent impedance that an acoustic wave will encounter as it reaches the end of the supply tube. Upon invoking this boundary condition, significantly improved agreement between the test data and the model was realized.

    An electrostatic kicker has been constructed for use in the Low-Energy Undulator Test Line (LEUTL) at the Advanced Photon Source (APS). The function of the kicker is to limit the amount of beam current to be accelerated by the APS linac. Two electrodes within the kicker create an electric field that adjusts the trajectory of the beam.

    The current study describes a fatal Mycoplasma bovis infection in a North American bison (Bison bison) cow and her aborted fetus in a herd suffering unusual mortality associated with dystocia and abortion. Postmortem evaluation of the subject case found severe caseonecrotic bronchopneumonia, chronic fibrinous pleuritis and pulmonary sequestra, foci of caseous necrosis in the kidneys, and necrotizing endometritis and placentitis. Histologic findings in the maternal tissues include endometrial and placental necrotizing vasculitis and changes in the lung similar to those previously described for M. bovis-associated pneumonia in feedlot bison. Gross and microscopic lesions were not observed in the fetus. Maternal lung, uterus, kidney, and placenta as well as fetal lung and kidney were positive for M. bovis by polymerase chain reaction (PCR) as were the Mycoplasma-like colonies cultured from these tissues. The presence of M. bovis in maternal and fetal tissues was further demonstrated using nucleic acid extracts in a pan-Mycoplasma SYBR Green PCR assay targeting the 16S-23S ribosomal RNA spacer region with post-PCR dissociation curve analysis and sequencing of the resulting amplicons. Immunohistochemistry (IHC) testing on maternal lung and uterine caruncle was strongly positive for M. bovis antigen. A variety of methods, including culture, PCR, and IHC, failed to identify other bacterial or viral pathogens in any of the tissues evaluated. These data are the first to implicate M. bovis as a cause of placentitis and abortion in bison.

    supplementation. In the third group, the autoimmune diseases, especially systemic lupus erythematosus (SLE) are most likely a cause of fetal wastage, by secreting antibodies that cross-react with the antigenic determinants of the trophoblast. These patients should be screened for lupus like anticoagulant; the therapy with glucocorticoids during pregnancy is still debated. More recently, the immunologic factors have been estimated to play an important role in the etiology of usual abortion: in these cases women share HLA antigens with their partners more frequently than expected.(ABSTRACT TRUNCATED AT 400 WORDS)

  3. Harmonic Resonant Kicker Design for the MEIC Electron Circular Cooler Ring

    Bunched-beam electron cooling of the high-energy ion beam emittance may be a crucial technology for the proposed Medium energy Electron Ion Collider (MEIC) to achieve its design luminosity. A critical component is a fast kicker system in the Circular Ring (CR) that periodically switches electron bunches in and out of the ring from and to the driver Energy Recovery Linac (ERL). Compared to a conventional strip-line type kicker, a quarter-wave resonator (QWR)-based deflecting structure has a much higher shunt impedance and so requires much less RF power. The cavity has been designed to resonate simultaneously at many harmonic modes that are integer multiples of the fundamental mode. In this way the resulting waveform will kick only a subset of the circulating bunches. In this paper, analytical shunt impedance optimization, the electromagnetic simulations of this type of cavity, as well as tuner and coupler concept designs to produce 5 odd and 5 even harmonics of 47.63MHz will be presented, in order to kick every 10th bunch in a 476.3 MHz bunch train.

  4. Abortion and infertility in Russia.

    The exceptionally high rate of induced abortion in Russia (204/100 live births in 1991) and of abortion-related genital tract infection and infertility implies an urgent need for both the prevention of unwanted pregnancy and less invasive abortion techniques. Vacuum aspiration is gradually replacing curettage as the abortion method of choice for first-trimester abortions, and research is being conducted on pharmacologic abortion involving prostaglandins in combination with RU-486. Infertility, which affects 10-15% of married Russian couples, accounts for 50% of visits to the largest gynecologic hospitals. 92% of women and 49% of men in couples with impaired fertility exhibit pathology of the reproductive system, primarily prior inflammatory morbidity of the genitalia. The use of surgery to correct these impairments is largely unsuccessful, especially when there has been prior treatment with the hydroturbation method. The Federal Family Planning Program for 1993-97 reflects increased awareness of the problem; among its goals are the creation of state and social structures for a family planning service, mass media campaigns, the preparation of educational materials on the avoidance of unwanted pregnancy, and staff training in sex education and family planning.

    We use unique data on abortions performed in New York State from 1971–1975 to demonstrate that women travelled hundreds of miles for a legal abortion before Roe. A100- mile increase in distance for women who live approximately 183 miles from New York was associated with a decline in abortion rates of 12.2 percent whereas the same change for women who lived 830 miles from New York lowered abortion rates by 3.3 percent. The abortion rates of nonwhites were more sensitive to distance than those of whites. We found a positive and robust association between distance to the nearest abortion provider and teen birth rates but less consistent estimates for other ages. Our results suggest that even if some states lost all abortion providers due to legislative policies, the impact on population measures of birth and abortion rates would be small as most women would travel to states with abortion services.

    The difficulties with damping ring kickers that prevented operation of the SLAC Linear Collider in full multiple bunch mode have been overcome by shaping the current pulse to compensate for imperfections in the magnets. The risetime was improved by a peaking capacitor, with a tunable inductor to provide a locally flat pulse. The pulse was flattened by an adjustable droop inductor. Fine adjustment was provided by pulse forming line tuners driven by stepping motors. Further risetime improvement will be obtained by a saturating ferrite pulse sharpener. 4 refs., 3 figs.

    A high speed, high repetition rate, bipolar solid-state high voltage modulator is under development at Brookhaven National Laboratory for Muon Electron Conversion (MECO) Experiment. The modulator will be used to drive a RF kicker consisting a pair of parallel deflecting plates. The principle design is based on the inductive-adder topology. This system requires a fast pulse rise and fall time about 20ns, a pulse width of 100ns, a pulse repetition rate of 300 kHz, and a 60 kHz sine-wave amplitude modulation. The fast high voltage MOSFETs are used as main switching devices.Different magnetic materials are being investigated for adder core magnets. The main circuit design, critical subsystems, and major technical issues will be discussed. The circuit simulation, components selection and evaluation, and preliminary test results will be presented.

  11. Spain still in need of a good abortion law.

    In 1985 Spain adopted a new abortion law that allows women to have abortions if: 1) the pregnancy poses a physical or mental risk, 2) the fetus risks a defect, 3) in cases of rape. 94% of all abortions are carried out in private clinics. Before the law only 411 abortions were reported, after the law 16,766 were reported the next year. 52% of the women were unmarried, 49% had no children, and 93% were less than 12 weeks pregnant. The availability of safe abortions is limited by: 1) lack of centers in most geographical regions and 2) lack of clinics or hospitals in the public health system that will give abortion services. The addition of 4th ground for abortion would not significantly improve access to abortion services since 98% of all abortions are performed under the mental risk indication. A better solution would be to adopt a time limit system similar to other European countries. Since 93% of all abortion occur within 12 weeks of pregnancy, it would accommodate most women. However, whether by executive order or legislation, increasing legal access will still not increase access. There simply is n system in place to accommodate the number of women who would seek abortions i they became legal (it is estimated that 200000 women got to England annually seeking abortion.) Doctors do not want to perform abortions and there is no social or legal standing to force them to do so. PMID:12284545

    A safe induced abortion has no impact on future fertility. Ovulation may resume as early as 8 days after the abortion. There is no difference in return to fertility after medical or surgical abortion. Most women resume sexual activity soon after an abortion. Contraceptive counseling and provision should therefore be an integrated part of the abortion services to help women avoid another unintended pregnancy and risk, in many cases an unsafe, abortion. Long-acting reversible contraceptive methods that includes implants and intrauterine contraception have been shown to be the most effective contraceptive methods to help women prevent unintended pregnancy following an abortion. However, starting any method is better than starting no method at all. This Special Report will give a short guide to available methods and when they can be started after an induced abortion.

    Abortion stigma is widely acknowledged in many countries, but poorly theorised. Although media accounts often evoke abortion stigma as a universal social fact, we suggest that the social production of abortion stigma is profoundly local. Abortion stigma is neither natural nor 'essential' and relies upon power disparities and inequalities for its formation. In this paper, we identify social and political processes that favour the emergence, perpetuation and normalisation of abortion stigma. We hypothesise that abortion transgresses three cherished 'feminine' ideals: perpetual fecundity; the inevitability of motherhood; and instinctive nurturing. We offer examples of how abortion stigma is generated through popular and medical discourses, government and political structures, institutions, communities and via personal interactions. Finally, we propose a research agenda to reveal, measure and map the diverse manifestations of abortion stigma and its impact on women's health.

  16. Extraction Kickers and Modulators for the advanced Hydrodynamic Facility

    2001-06-12

    In order to exploit the full potential of the Advanced Hydrodynamic Facility (AHF) facility to produce a time sequence of proton transmission radiographs throughout the dynamic event, a kicker/modulator for extraction from the 50 GeV ring that is capable of generating a string of 25 pulse pairs at arbitrary times within a total time duration of 100 microseconds or more is desired. The full range of desired pulse-train requirements cannot be met with the commonly used pulse-forming cables or networks (PFNs) switched with thyratrons. The preferred modulator design approach at present is a transformer voltage-adder concept with primary-side pulses formed with MOSFET-switched capacitors. This modulator will be a scale-up of an existing modulator that has been developed by Lawrence Livermore National Laboratory for use in DARHT, an electron induction accelerator facility at Los Alamos National Laboratory. Before the voltage-adder concept can be adopted for use in AHF, a working prototype that meets the AHF requirements for the pulse voltage, current, rise and fall time, and total pulse number must be built and tested. Additional requirements for pulse-to-pulse flattop height variation and baseline shift must also be met. A development and testing plan for the voltage-adder kicker modulator for AHF is described.

    Abortion is not only a major cause of obstetric hospitalization in poor countries, but it also represents the failure of the public health system to provide enough information about contraceptive methods and thus prevent pregnancies. In Brazil, the high utilization rates of health facilities due to abortions reflect the ongoing difficulties with family planning and contraception. In addition, mortality resulting from abortions serves as an indicator of the quality of abortion procedures, an important point in a country where the practice is illegal and therefore done clandestinely. In this study, we analyzed the rates of mortality resulting from abortions among women 10 to 54 years old, including women who died from spontaneous and induced abortion, from 1980 to 1995, for the various regions of the country. The information we used came from the mortality data bank of the public health system of the Ministry of Health. Population data were obtained from the Brazilian Institute for Geography and Statistics. We studied 2,602 deaths, 15% of which were due to missed abortion, spontaneous abortion, or legally permitted induced abortion. The other 85% of the deaths were due to illegal induced abortions or to nonspecified abortions. The mortality rates from abortion-related causes have steadily decreased in all the regions of Brazil, but this improvement has been unevenly distributed in the country. The region with the smallest decrease in this rate (38% over 15 years) was the Northeast. The age of women dying from abortions progressively declined over the period studied.

    Howell, N R

    1997-01-01

    This paper argues that religious communities should pose new questions about abortion in an attempt to reinvigorate the abortion debate and make it more constructive. Such questions would break the current impasse, enlarge the global and ecological scope of abortion inquiry, and engage plural religious perspectives in an interreligious dialogue about justice and abortion. After an introduction, the paper discusses the first impasse in the abortion debate, which is caused by conflicting definitions of personhood that create a fetus/pregnant woman dualism and artificially separate the fetus from its interdependence with the mother. Section 2 looks at how the abortion impasse results from the assertions of competing fetal and maternal rights and from conflict over who controls nature and women's bodies. The third section seeks alternatives to the dichotomizing of individual and community in the abortion debate in Christian theology, such as the notion of the relational self that demands attention to the wider social implications of reproduction. By examining theories that presume that people are relational, section 4 locates the abortion debate in a wider ecological context with concerns about overpopulation and environmental degradation. Section 5 explores questions of what authority can be used to determine whether abortion is ever justifiable for Christians and what authority is relevant for determining a Christian theological ethic of abortion. This section also looks at Jewish, Muslim, Hindu, and Buddhist views of abortion in the belief that the complex ethical issues relating to abortion may be explored through religious ritual.

    The Fermilab Antiproton Source Accumulator and Debuncher rings require 5 kickers in total. These range in design from conventional ferrite delay line type magnets, with ceramic beam tubes to mechanically complex shuttered kickers situated entirely in the Accumulator Ring's 10/sup -10/ torr vacuum. Power supplies are thyratron switched pulse forming networks that produce microsecond width pulses of several kiloamps with less than 30 nanoseconds rise and fall times. Kicker and power supply design requirements for field strength, vacuum, rise and fall time, timing and magnetic shielding of the stacked beam in the accumulator by the eddy current shutter will be discussed. 8 refs., 3 figs., 2 tabs.

    While most countries of the world practice abortion, government policy, medical opinion, private opinion and actual practice vary widely. Although mortality from legal abortions is quite low, complications rise sharply after 12 gestational weeks. No conclusive proof shows adverse postabortion psychological effects. Romania, Japan and the Soviet Union experienced declining birth rates when abortion was made available and New York City saw a decline in illegitimacy of approximately 12% from 1970 to 1971. Throughout the world abortion laws vary from restrictive to moderate to permissive. Where laws are restrictive, as in France and Latin America, illegal abortions are estimated in the millions. The controversy over abortion centers around the arguments of what constitutes a human life, and the rights of the fetus versus the right of a woman to control her reproductive life. A review of state abortion laws as of August 1972 shows pressure on state legislatures to change existing laws. The future of abortion depends upon technological advances in fertility control, development of substitutes like menstral extraction, prostaglandins and reversible sterilization. Development of these techniques will take time. At present only through education and improved delivery of contraceptives can dependence on abortion as a method of fertility control be eased. Citizen education in the United States, both sex education and education for responsbile parenthood, is in a poor state according to the Commission on Population Growth and the American Future. If recourse to abortion is to be moderated, it is the next generation of parents who will have to be educated.

    In France, under the terms of a law passed by Parliament in 1975, a woman may have an abortion up to 12 weeks of pregnancy if she is a French resident and, in the event that she is a minor, she has parental consent. The woman must also have 2 medical consultations, a week apart. The woman is reimbursed by the state up to 70% of the cost of the abortion. After 12 weeks, abortion, except for therapeutic abortion, under the terms of Article 317 of the Criminal Code, is a crime, punishable by 6 months to 10 years in prison, a fine of between 1800 and 250,000 Francs, and loss of professional license. Moreover, Article 647 of the Health Code bans any advertising, incitement or propaganda for abortion or abortion-inducing products. Many French women go to Britain or Holland for abortions after 12 weeks, but they face the financial burden of traveling as well as the difficulties of getting help in a strange country and the stigma of having done something illegal. The Mouvement Francais pour le Planning Familial, which won the legalization of contraception in 1967, is now fighting for legal abortion as well as the distribution of information about sexuality, contraception, and abortion in the schools. 2 charges of incitement to abortion have been brought against the organization.

    The Crew Exploration Vehicle (CEV) is required to maintain continuous abort capability from lift off through destination arrival. This requirement is driven by the desire to provide the capability to safely return the crew to Earth after failure scenarios during the various phases of the mission. This paper addresses abort trajectory design considerations, concept of operations and guidance algorithm prototypes for the portion of the ascent trajectory following nominal jettison of the Launch Abort System (LAS) until safe orbit insertion. Factors such as abort system performance, crew load limits, natural environments, crew recovery, and vehicle element disposal were investigated to determine how to achieve continuous vehicle abort capability.

    Removing abortion from the Criminal Code in Canada will mean that more and more abortions will be performed for nonmedical reasons which will result in an abortion-on-demand situation similar to that in Japan. Early complications of abortion include death, hemorrhage, shock, cervical injury, and infection. Later complications include premature births, spontaneous abortions, ectopic pregnancies, pelvic inflammation, and infertility. Legalized abortion does not seem to reduce the incidence of illegal abortion. There are also psychological, moral, and sociological consequences of legalized abortion. It would seem that liberal abortion makes bad medicine and leads to far-reaching consequences.

    This piece describes abortion practices in use from the 1600s to the 19th century among the inhabitants of North America. The abortive techniques of women from different ethnic and racial groups as found in historical literature are revealed. Thus, the point is made that abortion is not simply a "now issue" that effects select women. Instead, it is demonstrated that it is a widespread practice as solidly rooted in our past as it is in the present.

    Diniz, D; Gonzalez Velez, A C

    1998-06-01

    Although abortion has been the most debated of all issues analyzed in bioethics, no moral consensus has been achieved. The problem of abortion exemplifies the difficulty of establishing social dialogue in the face of distinct moral positions, and of creating an independent academic discussion based on writings that are passionately argumentative. The greatest difficulty posed by the abortion literature is to identify consistent philosophical and scientific arguments amid the rhetorical manipulation. A few illustrative texts were selected to characterize the contemporary debate. The terms used to describe abortion are full of moral meaning and must be analyzed for their underlying assumptions. Of the four main types of abortion, only 'eugenic abortion', as exemplified by the Nazis, does not consider the wishes of the woman or couple--a fundamental difference for most bioethicists. The terms 'selective abortion' and 'therapeutic abortion' are often confused, and selective abortion is often called eugenic abortion by opponents. The terms used to describe abortion practitioners, abortion opponents, and the 'product' are also of interest in determining the style of the article. The video entitled "The Silent Scream" was a classic example of violent and seductive rhetoric. Its type of discourse, freely mixing scientific arguments and moral beliefs, hinders analysis. Within writings about abortion three extreme positions may be identified: heteronomy (the belief that life is a gift that does not belong to one) versus reproductive autonomy; sanctity of life versus tangibility of life; and abortion as a crime versus abortion as morally neutral.

    Although abortion has been the most debated of all issues analyzed in bioethics, no moral consensus has been achieved. The problem of abortion exemplifies the difficulty of establishing social dialogue in the face of distinct moral positions, and of creating an independent academic discussion based on writings that are passionately argumentative. The greatest difficulty posed by the abortion literature is to identify consistent philosophical and scientific arguments amid the rhetorical manipulation. A few illustrative texts were selected to characterize the contemporary debate. The terms used to describe abortion are full of moral meaning and must be analyzed for their underlying assumptions. Of the four main types of abortion, only 'eugenic abortion', as exemplified by the Nazis, does not consider the wishes of the woman or couple--a fundamental difference for most bioethicists. The terms 'selective abortion' and 'therapeutic abortion' are often confused, and selective abortion is often called eugenic abortion by opponents. The terms used to describe abortion practitioners, abortion opponents, and the 'product' are also of interest in determining the style of the article. The video entitled "The Silent Scream" was a classic example of violent and seductive rhetoric. Its type of discourse, freely mixing scientific arguments and moral beliefs, hinders analysis. Within writings about abortion three extreme positions may be identified: heteronomy (the belief that life is a gift that does not belong to one) versus reproductive autonomy; sanctity of life versus tangibility of life; and abortion as a crime versus abortion as morally neutral. Most individuals show an inconsistent array of beliefs, and few groups or individuals identify with the extreme positions. The principal argument of proponents of legalization is respect for the reproductive autonomy of the woman or couple based on the principle of individual liberty, while heteronomy is the main principle of

    Partial-birth abortion bans patterned after the federal bill passed by both houses of Congress are constitutional. The clear legislative definition can be easily distinguished from other abortion procedures. Abortion precedents do not apply to such bans because the abortion right pertains to unborn human beings, not to those partially delivered. Such bans are also rationally-related to legitimate state interests. Even if abortion jurisprudence is deemed to apply in the partial-birth abortion context, a ban is still constitutional under Casey because a ban on partial-birth abortions does not impose an undue burden on the abortion right.

  13. Algorithm for Determination of Orion Ascent Abort Mode Achievability

    2011-01-01

    For human spaceflight missions, a launch vehicle failure poses the challenge of returning the crew safely to earth through environments that are often much more stressful than the nominal mission. Manned spaceflight vehicles require continuous abort capability throughout the ascent trajectory to protect the crew in the event of a failure of the launch vehicle. To provide continuous abort coverage during the ascent trajectory, different types of Orion abort modes have been developed. If a launch vehicle failure occurs, the crew must be able to quickly and accurately determine the appropriate abort mode to execute. Early in the ascent, while the Launch Abort System (LAS) is attached, abort mode selection is trivial, and any failures will result in a LAS abort. For failures after LAS jettison, the Service Module (SM) effectors are employed to perform abort maneuvers. Several different SM abort mode options are available depending on the current vehicle location and energy state. During this region of flight the selection of the abort mode that maximizes the survivability of the crew becomes non-trivial. To provide the most accurate and timely information to the crew and the onboard abort decision logic, on-board algorithms have been developed to propagate the abort trajectories based on the current launch vehicle performance and to predict the current abort capability of the Orion vehicle. This paper will provide an overview of the algorithm architecture for determining abort achievability as well as the scalar integration scheme that makes the onboard computation possible. Extension of the algorithm to assessing abort coverage impacts from Orion design modifications and launch vehicle trajectory modifications is also presented.

    The effect of possible accidental beam loss in the LHC on the IP5 and IP6 insertion elements is studied via realistic Monte Carlo simulations. The scenario studied is beam loss due to unsynchronized abort at an accidental prefire of one of the abort kicker modules. Simulations show that this beam loss would result in severe heating of the IP5 and IP6 superconducting (SC) quadrupoles. Contrary to the previous considerations with a stationary set of collimators in IP5, collimators in IP6 close to the cause are proposed: a movable collimator upstream of the Q4 quadrupole and a stationary one upstream of the extraction septumMSD. The calculated temperature rise in the optimal set of collimators is quite acceptable. All SC magnets are protected by these collimators against damage.

    To minimize the beam losses at the moment of an LHC beam dump the 3 μs long abort gap should contain as few particles as possible. Its population can be minimised by abort gap cleaning using the LHC transverse damper system. The LHC Run 1 experience is briefly recalled; changes foreseen for the LHC Run 2 are presented. They include improvements in the observation of the abort gap population and the mechanism to decide if cleaning is required, changes to the hardware of the transverse dampers to reduce the detrimental effect on the luminosity lifetime and proposed changes to the applied cleaning algorithms.

    Is there a relationship between restrictive state abortion laws and postpartum depression? Do states with restrictive abortion laws have higher rates of postpartum depression? If there is a relationship, does it differ by the type of restrictive state abortion law? Using the Centers for Disease Control's 2008 Pregnancy Risk Assessment Monitoring System state survey of the percentage of women who gave birth and suffered from postpartum depression, states with and without restrictive abortion laws were compared. The empirical results found that there were no significant differences in the incidence of postpartum depression between states with parental involvement laws, mandatory counseling laws, waiting period laws, two-visit laws, and states without these restrictive abortion laws. States that prohibit the Medicaid funding of abortions have significantly higher rates of postpartum depression than in those states that fund Medicaid abortions. PMID:25068613

    As of July 1991 abortion is still legal in Poland. Currently the Polish Parliament has taken a break from the debate because the issue is so important that any decision must not be made in past. There is strong pressure from the Catholic Church to eliminate access to abortion. In the fall the Polish people will vote for and elect their first truly democratic Parliament. Abortion does not seem to be playing as important a role as other political issues. In 1956 a law was passed that allowed a woman to have an abortion for medical or social reasons. This law resulted in allowing women in Poland to use abortion as their primary form of contraception. The vast majority of the abortions were performed under the social justification. Then, when democracy same to Poland with the help of the Catholic Church, an unprecedented debate in the mass media, churches, and educational institutions was stirred up. The government attempted to stay out of the debate at first. But as people from different side of the debate saw that they had an opportunity to influence things in their favor, they began to politicize the issue. Currently there are 4 different drafts of the new Polish abortion law. 3 of them radically condemn abortion while the 4th condemns it as a method of family planning, but allows to terminate pregnancies in order to save the life of the mother.

    In Japan, the artificial abortion is a penal offence; only in the presence of certain conditions it is authorized under the provision of the Eugenic Protection Law which was promulgated in 1948. According to the law, the artificial abortion is restricted to the period, in which the fetus is not viable outside of the uterus. This period is prescribed by notification from the Ministry of Public Welfare; up to now it has been shortened twice (1976, 1991). Due to the introduction of economic reasons in the list of conditions and the simplification of the procedure the artificial abortion in Japan was virtually liberalized. Prosecution for illegal abortion is very rare in recent years. The number of reported artificial abortions decreases; in the about last 30 years it reduced by half. However, the increase in the number of abortions in women younger than 20 years of age is a problem. The abortion in teenagers is late compared with that in other age groups. Although the number of neonaticides does not seem to increase, the increase in the number of abortions in teenagers remains a serious problem in Japan. PMID:8352642

    Responses to the question as to whether abortions should be performed at the woman's request during the first trimester of pregnancy were evenly divided. There was support for abortion on socioeconomic grounds, during the first trimester, from 61.5% of the respondents. Termination of pregnancy beyond the first trimester was supported by a majority of the respondents only in cases in which the woman's life is in danger (73.9%) or in which there is evidence of a severe physical abnormality in the fetus (70.6%) or in cases in which the woman's physical health is in danger (55.5%). Those who said they would not support abortion under any circumstances constitute, at most, 5.1% of the respondents. Support for the maintenance or the elimination of therapeutic abortion committees was addressed in two questions and in both cases the respondents were evenly divided. The responses to these two questions were compared and found to be logically consistent. Only physicians should perform abortions, and they should be performed in hospitals with the woman either as an inpatient or, during the first trimester, as an outpatient. The performance of first-trimester abortions in provincially approved abortion clinics was supported by 47.3% of the respondents. Of the 885 respondents who wished to see some amendment to the Criminal Code, 409 stated that the term "health" as used in the Criminal Code relative to the legal grounds for therapeutic abortion should be defined.

    An important element in the design of NASA's Crew Exploration Vehicle (CEV) is the consideration given to crew safety during various ascent phase failure scenarios. To help ensure crew safety during this critical and dynamic flight phase, the CEV requirements specify that an abort capability must be continuously available from lift-off through orbit insertion. To address this requirement, various CEV ascent abort modes are analyzed using 3-DOF (Degree Of Freedom) and 6-DOF simulations. The analysis involves an evaluation of the feasibility and survivability of each abort mode and an assessment of the abort mode coverage using the current baseline vehicle design. Factors such as abort system performance, crew load limits, thermal environments, crew recovery, and vehicle element disposal are investigated to determine if the current vehicle requirements are appropriate and achievable. Sensitivity studies and design trades are also completed so that more informed decisions can be made regarding the vehicle design. An overview of the CEV ascent abort modes is presented along with the driving requirements for abort scenarios. The results of the analysis completed as part of the requirements validation process are then discussed. Finally, the conclusions of the study are presented, and future analysis tasks are recommended.

  3. Abortion: a history.

    1985-01-01

    This review of abortion history considers sacred and secular practice and traces abortion in the US, the legacy of the 19th century, and the change that occurred in the 20th century. Abortion has been practiced since ancient times, but its legality and availability have been threatened continuously by forces that would denigrate women's fundamental rights. Currently, while efforts to decrease the need for abortion through contraception and education continue, access to abortion remains crucial for the well-being of millions of women. That access will never be secure until profound changes occur in the whole society. Laws that prohibit absolutely the practice of abortion are a relatively recent development. In the early Roman Catholic church, abortion was permitted for male fetuses in the first 40 days of pregnancy and for female fetuses in the first 80-90 days. Not until 1588 did Pope Sixtus V declare all abortion murder, with excommunication as the punishment. Only 3 years later a new pope found the absolute sanction unworkable and again allowed early abortions. 300 years would pass before the Catholic church under Pius IX again declared all abortion murder. This standard, declared in 1869, remains the official position of the church, reaffirmed by the current pope. In 1920 the Soviet Union became the 1st modern state formally to legalize abortion. In the early period after the 1917 revolution, abortion was readily available in state operated facilities. These facilities were closed and abortion made illegal when it became clear that the Soviet Union would have to defend itself against Nazi Germany. After World War II women were encouraged to enter the labor force, and abortion once again became legal. The cases of the Catholic church and the Soviet Union illustrate the same point. Abortion legislation has never been in the hands of women. In the 20th century, state policy has been determined by the rhythms of economic and military expansion, the desire for cheap

    Sir Dugald Baird sketches the history of abortion legislation in Great Britain from the beginning of the century. In his views the 1967 Abortion Act has been one of the most important and beneficial pieces of social legislation enacted in Britain in the last 100 years. It has, however, brought problems both of administration in the hospitals and to individual doctors and nurses, particularly when the patients are young single women and even schoolgirls. One of the consequences of the Abortion Act has been a fall in maternal mortality and perinatal mortality rates. Abortion does not seem to be followed by serious emotional sequelae. Nevertheless recent changes in sexual mores have introduced new and serious social problems which are discussed in relation to the role of the doctor in his relationship with patients seeking abortion.

    The abortion controversy in England was partially resolved on February 23, 1971, when Sir Keith Joseph, Secretary of State for Social Services, announced that an inquiry into the 1967 Abortion Act would be established, but one which would be concerned with the way the Act was working rather than the principles underlying it. Regional inequalities exist in the implementation of the Act (as with substandard services in Birmingham, Liverpool and Sheffield) due to opposition of the local gynecological establishment and a genuine shortage of facilities. These can be eliminated only through time and retirement and with public finance for more equal abortion facilities. The addition of a consultant clause into the Act would probably reduce the number of abortions in smaller private nursing homes, flood the National Health Service with abortion requests, and drive women back to criminal abortionists.

    Injection into the two MAX IV storage rings will not make use of a 4-kicker local injection bump. Instead, pulsed multipole injection will be used for initial filling as well as top-up injection. Since commissioning a pulsed multipole magnet for injection into a storage ring is non-trivial, it has been decided to install a single dipole kicker magnet into the storage rings to provide a simple method for injection during early commissioning. Design studies have revealed that injection with a single dipole kicker into the MAX IV storage rings is not only efficient, but also allows for accumulation of beam. Although this accumulation cannot be made transparent to users (i.e. it is not compatible with user top-up operation), it does provide a simple and robust injection method during commissioning. In addition, the dipole kicker can be used as a pinger magnet during machine studies with a single-bunch filling. This paper reports on the design studies performed for dipole kicker injection into the MAX IV storage rings and presents a summary of the expected performance of such an injection scheme.

    For years suffering of Booster Injection Kicker transistor bank driver regulator troubleshooting, a new real time monitor system has been developed. A simple and floating circuit has been designed and tested. This circuit monitor system can monitor the driver regulator power limit resistor status in real time and warn machine operator if the power limit resistor changes values. This paper will mainly introduce the power supply and the new designed monitoring system. This real time resistor monitor circuit shows a useful method to monitor some critical parts in the booster pulse power supply. After two years accelerator operation, it shows that this monitor works well. Previously, we spent a lot of time in booster machine trouble shooting. We will reinstall all 4 PCB into Euro Card Standard Chassis when the power supply system will be updated.

    Ceramic chambers will be used in the pulsed kicker magnets for the injection of H{sup -} into the Spallation Neutron Source (SNS) accumulator ring, to avoid shielding of a fast-changing external magnetic field by metallic chamber walls and to reduce eddy current heating. The inner surfaces of the ceramic chambers will be coated with a conductive layer, possibly titanium (Ti) or copper (Cu) with a titanium nitride (TiN) overlayer, to reduce the beam coupling impedance, provide passage for beam image current and to reduce the secondary electron yields. This paper describes the development of sputtering method for the 0.83m long 16cm inner diameter (ID) ceramic chambers. Coatings of Ti, Cu and TiN with thickness up to 10 {micro}m were produced by means of DC magnetron sputtering. The difficulty of coating insulators was overcome with the introduction of an anode screen. Films with good adhesion, uniform longitudinal thickness, and conductivity were produced.

    It is argued that abortion research is needed to improve existing techniques and to develop new ones to overcome logistical, financial, and political obstacles to wider availability. Such developments are reviewed, including early pregnancy tests, menstrual regulation, improved cervical dilatation methods, new second trimester abortifacients (e.g., urea and prostaglandins), and new first trimester abortifacients (e.g., injection of ethanol into the uterus and prostaglandin pills or vaginal suppositories). This last is quite promising because of the possibility of self-administration, removing much of the need for medical intervention. Further research is urged on 1) long-term side effects of abortion, particularly late or multiple abortions; and 2) ways to improve the delivery and integration of abortions into family planning programs. It is noted that because abortion seekers demonstrate by the fact itself a strong motivation to control fertility and are therefore enthusiastic acceptors of contraceptive methods, the widespread availability of early pregnancy tests and abortion could be the most effective way of increasing contraceptive practice and reducing abortion itself.

  11. Avoidance of late abortion.

    PubMed

    1979-11-24

    Induced abortion is now a common procedure in the United States and Britain. Methods for performing induced abortion are reviewed. Menstrual regulation, aspiration with a hand-held syringe and a flexible cannula within 6 weeks of the last period, is not often practiced in Britain. Several developing countries are using this simple technique to advantage. Vacuum aspiration in the 1st 12 weeks of pregnancy is the main method being used everywhere for 1st trimester procedures. Mortality rates with this method are low and, in well-organized clinics with experienced personnel, the rates can be reduced even further. It is agreed that 2nd trimester procedures are more complex, both physically and emotionally. In the last several years, dilatation and evacuation (D&E) has increased in popularity for 2nd trimester procedures. Dilation of the cervix is generally accomplished with laminaria, evacuation of the uterus with forceps, and then suction curettage applied. This procedure has replaced intraamniotic infusion, hysterotomy, and hysterectomy as the most commonly - practiced method, despite its need for special surgical skills and good clinical backup. Follow-up of abortions is difficult. Different long-term effects have been noted with different abortion procedures. Early abortion seems to have only a modest effect, if that. Whether late abortion has long-lasting effects remains open to question. Late abortion should be avoided.

    The writer believes that life begins the instant that an human sperm cell and ovule fuse. This life must be respected and preserved. Abortion is shameful, but tolerated when either the mother or would-be baby's life is at stake. As the number of abortions continue to increase, the controversy over a woman's right to abortion rages on. The author wonders whether questions about abortion will ever be resolved and considers some possible solutions with reference to Zambia. There are many early pregnancies among Zambian youths. A 1993 study found 207 abortions per year in the country among 15-19 year olds; this includes illegal, incomplete, and induced abortions. The Coordinator for the Young Women Christian Association in Lusaka thinks that inadequate sex education is one of the factors contributing to the ever-rising number of abortions today. Youths have sexual intercourse without understanding the possible consequences. Parents, community leaders, and school authorities should instead become more involved and teach children about sex to lessen the incidence of abortion. Specifically, parents should talk to their children about sex as they mature, teaching them about their biological reproductive features and functions. The author is convinced that once children and youths understand their bodies, it will be very easy for them to control their desires. Most male and female teens do, however, cite love and sexual desire as the primary motives for their first relationships. The writer also mentions how pregnant girls get expelled from school and that women experience mental and physical side effects from induced abortion.

    Carpet layers have a high prevalence of occupational knee morbidity. One of the main causes is that they need to frequently 'kick' the bumper on the rear end of the knee kicker with one knee when laying a carpet. Considering the bumper's marked effects on kicking force transmission and safety, this study aims to improve the design of the knee-kicker bumper by reducing the risk factors. An improved pendulum-type impact-testing platform was designed as an evaluative apparatus, with the impulse and the coefficient of restitution serving as evaluative criteria. The newly developed bumper has improved firmness from drilled blind holes and an increase in effective forward force of 15%-138%, which implies lower operational demands and a lighter knee burden (i.e., less kicking energy results in the same work efficiency), and a softer contact surface that enhances operating comfort. The newly designed kicker was positively reviewed by subjects.

    A solid-state modulator with very fast rise and fall times, pulse width agility, and multi-pulse burst and intra-pulse amplitude adjustment capability for use with high speed electron beam kickers has been designed and tested at LLNL. The modulator uses multiple solid-state modules stacked in an inductive-adder configuration. Amplitude adjustment is provided by controlling individual modules in the adder, and is used to compensate for transverse e-beam motion as well as the dynamic response and beam-induced steering effects associated with the kicker structure. A control algorithm calculates a voltage based on measured e-beam displacement and adjusts the modulator to regulate beam centroid position. This paper presents design details of amplitude control along with measured performance data from kicker operation on the ETA-II accelerator at LLNL.

    2002-04-01

    Fast traveling-wave extraction kickers contain no ferrite and consist of two long metallic parallel plates supported by insulators inside a beam pipe. A beam is deflected by both the electric and magnetic fields of a TEM wave created by a pulse propagating along the strips in the direction opposite to the beam. Computations of the beam coupling impedances for such structures are difficult because of their length. In the paper, the beam coupling impedances of such transmission-line kickers are calculated by combining analytical and numerical methods: the wake potentials computed in short models are extended analytically to obtain the wakes for the long kickers, and then the corresponding beam impedances are derived. As one can expect, at very low frequencies the results are in agreement with simple analytical expressions available for the coupling impedances of striplines in beam position monitors.

    The Los Alamos Neutron Science Center (LANSCE) is installing two beam lines to both improve operational tuning and provide new capabilities within the facility. The Isotope Production Facility (IPF) will provide isotopes for medical purposes by using the H' beam spur at 100 MeV and the Switchyard Kicker Upgrade (SYK) will allow the LANSCE 800-MeV H beam to be rapidly switched between various beam lines within the facility. The beam position measurements for both of these beam lines uses a standard micro-stripline beam position monitor (BPM) with both a 50-mm and 75-mm radius. The cable plant is unique in that it unambiguously provides a method of verifying the operation of the complete position measurement. The processing electronics module uses a log ratio technique with error corrections such that it has a dynamic range of -12 dBm to -85 dBm with errors less than 0.15 dB within this range. This paper will describe the primary components of these measurement systems and provide initial data of their operation.

    This article reviews the current legal status of abortion in Australia and its implications. Australian abortion law has been a matter for the states since before Federation. In the years since Federation there have been significant reforms and changes in the abortion laws of some jurisdictions, although not all. Across Australia there are now nine sets of laws, state and Commonwealth, concerned with abortion. The test of a lawful abortion varies greatly across jurisdictions. In a number of states and territories, it is necessary to establish a serious risk to the physical or mental health of the woman if the pregnancy was to continue. In some cases, the certification of two doctors is required, particularly for abortions at later gestations. There are also physical restrictions on access, such as in South Australia and the Northern Territory where abortion must take place in a hospital. Only in the ACT has abortion been removed from the criminal law altogether. Variations in the law and restrictions arising from these are not consistent with the aims and provision of the universal, accessible health care system aspired to in Australia. There is an urgent need for overall reform and the introduction of uniformity to Australia's abortion laws, including removal of abortion from the criminal law.

    The Penal Code (Amendment) Bill or the abortion bill has the objective of liberalizing the current law on the regulation of abortion. Abortion had been strictly prohibited and carried stiff penalties. Anyone who attempted to assists a woman to procure an abortion could be liable to 7 years' imprisonment. However, medical abortions were distinguished as being medically determined to save the health of the mother. Demands for a reevaluation of the law came from the medical profession, and in response the Minister for Presidential Affairs submitted a bill to Parliament in November, 1990. The expressed government rationale for these proposed amendments was concern about the health of women. In Botswana about 200 women die yearly because of pregnancy. According to the proposed law: an abortion could be carried out within the first 16 weeks of pregnancy if: 1) the pregnancy were a result of rape, incest, or defilement (the impregnation of a girl aged 16 or less, the impregnation of imbeciles or idiots), 2) the physical or mental health of the woman were at risk because of the pregnancy, 3) the child would be born with a serious physical or mental abnormality. The abortion could be carried out only if 2 medical doctors approved it. The amendments fall far short of increasing women's control over their bodies. The Botswana Christian Council issued a statement early in the public debate. While it did not oppose the bill in its entirety, clear concern was expressed concerning the apparent right of determining who lives and who dies depending on the handicap of the child. This rather liberal position was challenged by the Roman Catholic Church which interpreted abortion as the murder of God-given life. The bill was nevertheless passed by Parliament in September 1991, and the President signed it on October 11, 1991. PMID:12288837

  20. Moderate views of abortion.

    PubMed

    Sumner, L W

    1997-01-01

    This essay offers a moderate view of abortion that imposes a time limit for unrestricted abortion and specific indications for later abortions. The introduction notes that the discussion will provide a defense for this policy based on a moral analysis but that other options for moderates, especially options provided by freestanding views (the defense of which does not rest on any prior commitment about the morality of abortion), will also be considered. The next section considers the moral status of the fetus grounded in a criterion of moral standing that stipulates the necessary characteristics to achieve moral standing. This discussion concludes that a fetus acquires moral standing only when it becomes sentient. Section 3 moves the argument from ethics to politics to prove that a moderate policy must place no limitations on abortion before the time the fetus becomes sentient because before that time the fetus has no interest for the state to protect. The final section notes that some pro-choice advocates may be happier with the moderate policy proposed than with its controversial defense based on the moral status of the fetus and that another defense of a moderate policy could be based on a finding that the ethical issue can not be decided and that no view about abortion ethics is more reasonable than any other. The essay concludes that the ethical debate is ultimately unavoidable. PMID:12348328

  1. Abortion and regret.

    PubMed

    Greasley, Kate

    2012-12-01

    The article considers three theses about postabortion regret which seek to illustrate its pertinence to reasoning about abortion, and which are often deployed, either explicitly or implicitly, to dissuade women out of that reproductive choice. The first is that postabortion regret renders an abortion morally unjustified. The second is that that a relatively high incidence of postabortion regret-compared with a lower incidence of postnatal regret in the relevant comparator field-is good evidence for the moral impermissibility of abortion choice. The third is that high rates of postabortion regret suggest that abortion is not the most prudent or welfare-maximising choice for the woman concerned. All three theses argue for the compellingness of knowledge about postabortion regret in moral and practical reasoning about abortion, especially from the pregnant woman's point of view. This article argues that all three theses are flawed. In particular, it seeks to remind readers that feelings of regret directed at past decisions are often decoupled from the fact of the matter about their moral or rational justification. Moreover, certain features of reproductive decisions in particular make regret an especially unsuitable yardstick for actual justification in this context, and even less epistemically reliable as evidence for a lack of justification than it may be in other fields of decision-making. The implication is that rates of postabortion regret, even if they can be presumed to be higher than rates of postnatal regret, are not as pertinent to moral and practical reasoning about abortion as is sometimes suggested.

  2. Politics and abortion.

    PubMed

    Rosoff, J I

    1985-01-01

    The legalization of abortion in the United States by the Supreme Court in 1973 bypassed the political process in the majority of the states. Since then, however, political controversy and agitation in relation to abortion has become nationwide. From largely Catholic-based opposition, it has grown to encompass religious fundamentalists and to be a major part of the New Right's agenda. Abortion is now, pro and con, part of the platform of both political parties. The sweeping nature of the Supreme Court's decisions leaves the opposition with very little room to restrict abortion, short of overturning the decisions through a constitutional amendment. Such an amendment requires a two-thirds majority of Congress and passage is unlikely. However, funding bans on scores of federal programmes have succeeded in restricting access to abortion for the poor, the young and minorities. These restrictions are part of a long-term strategy to educate the public as to the evils of abortion with the aim of making it illegal again, either through the adoption of a constitutional amendment or by obtaining a reversal by a hoped-for change in membership of the Supreme Court.

  3. Cambodia passes new limits on abortion.

    PubMed

    1997-10-17

    According to international news sources, Cambodia's parliament approved a law limiting the circumstances under which abortions can be performed on October 6 [1997]. Members of parliament say the new law, the first ever passed regulating abortion in Cambodia, is intended to reduce maternal morality rates from abortions performed by unlicensed health practitioners under unsanitary conditions. Local news outlets report that the Cambodian Health Ministry estimates the maternal mortality at 4.7 deaths per 1000 live births. The rate in the US is 0.12 deaths per 1000 live births. The law requires that abortions be performed by licensed health professionals in hospitals and certified clinics within the first trimester of pregnancy, and that women under the age of 18 must obtain parental consent. The new law also sets harsh penalties for those who harm women during illegal procedures--up to 5 years in prison if a woman is injured and up to 10 years if she dies. Opponents of the law say they fear that the new restrictions will push abortion even further underground, as the hospital system cannot handle the current demand for abortion. PMID:12292784

    Fast kicker magnets are needed in accelerators to deflect the beam out of the storage ring and into experimental targets and beam dumps. The work reported here is on a new type of fast kicker magnet. The basic idea is to transport the beam along the axis of a tube made of Type I superconductor. An ordinary magnet is used to create a field, B{sub o} perpendicular to the axis of the tube. If B{sub o}kicker field to the beam, B{sub o} is increased such that B{sub o}>B{sub c}. The tube of superconductor then goes normal. The field which had been shielded from the beam can now penetrate to the beam. This concept is applicable as a fast magnetic switch. DOE has been granted a patent on this device, which was disclosed to DOE by N.K. Mahale and D. Goren while they were at SSC. A feasibility study of this new form of kicker magnet is reported here.

    Until recently, WHO operationally defined unsafe abortion as illegal abortion. In the past decade, however, the incidence of abortion by misoprostol administration has increased in countries with restrictive abortion laws. Access to safe surgical abortions has also increased in many such countries. An important effect of these trends has been that, even in an illegal environment, abortion is becoming safer, and an updated system for classifying abortion in accordance with safety is needed. Numerous factors aside from abortion method or legality should be taken into consideration in developing such a classification system. An Expert Meeting on the Definition and Measurement of Unsafe Abortion was convened in London, UK, on January 9-10, 2014, to move toward developing a classification system that both reflects current conditions and acknowledges the gradient of risk associated with abortion. The experts also discussed the types of research needed to monitor the incidence of abortion at each level of safety. These efforts are urgently needed if we are to ensure that preventing unsafe abortion is appropriately represented on the global public health agenda. Such a classification system would also motivate investment in research to accurately measure and monitor abortion incidence across categories of safety. PMID:27062249

    This study describes foot positioning during the final two steps of the approach to the ball amongst professional rugby goal-kickers. A 3D optical motion capture system was used to test 15 goal-kickers performing 10 goal-kicks. The distance and direction of each step, as well as individual foot contact positions relative to the tee, were measured. The intra- and inter-subject variability was calculated as well as the correlation (Pearson) between the measurements and participant anthropometrics. Inter-subject variability for the final foot position was lowest (placed 0.03 ± 0.07 m behind and 0.33 ± 0.03 m lateral to the tee) and highest for the penultimate step distance (0.666 ± 0.149 m), performed at an angle of 36.1 ± 8.5° external to the final step. The final step length was 1.523 ± 0.124 m, executed at an external angle of 35.5 ± 7.4° to the target line. The intra-subject variability was very low; distances and angles for the 10 kicks varied per participant by 1.6-3.1 cm and 0.7-1.6°, respectively. The results show that even though the participants had variability in their run-up to the tee, final foot position next to the tee was very similar and consistent. Furthermore, the inter- and intra-subject variability could not be attributed to differences in anthropometry. These findings may be useful as normative reference data for coaching, although further work is required to understand the role of other factors such as approach speed and body alignment.

  8. A Solid-State Nanosecond Beam Kicker Modulator Based on the DSRD Switch

    A fast solid-state beam kicker modulator is under development at the SLAC National Accelerator Laboratory. The program goal is to develop a modulator that will deliver 4 ns, {+-}5 kV pulses to the ATF2 damping ring beam extraction kicker. The kicker is a 50 {Omega}, bipolar strip line, 60 cm long, fed at the downstream end and terminated at the upstream end. The bunch spacing in the ring is 5.6 ns, bunches are removed from the back end of the train, and there is a gap of 103.6 ns before the next train. The modulator design is based on an opening switch topology that uses Drift Step Recovery Diodes as the opening switches. The design and results of the modulator development are discussed. There are many applications that benefit from very fast high power switching. However, at MW power levels and nanosecond time scales, solid state options are limited. One option, the Drift Step Recovery Diode (DSRD) has been demonstrated as capable of blocking thousands of volts and switching in nanosecond to sub-nanosecond ranges. When used as an opening switch, the DSRD exhibits a very fast turn off transient. The process is described in detail by its pioneers in [5,6]. In essence, charge is pumped into and then extracted from the DSRD under pulsed conditions. The turn off transient occurs precisely when the pumped charge is equal to the extracted charge and the DSRD is switched off. At the SLAC National Accelerator Laboratory, a DSRD is being used as an opening switch in the development of a fast kicker modulator. The modulator is designed to create {+-}5kV pulses with <1ns rise and fall time on a 50{Omega} strip line kicker. As is common in beam optics, the absence of power in the kicker before and after the pulse is very important. The entire {+-}5kV kicker modulator is composed of two identical 5kV pulsing circuits, each with its own DSRD component. This paper describes the modulator topology and the status of tests on one of the two 5kV pulse circuits.

  9. Abortion and rape.

    PubMed

    Barry-Martin, P

    1977-10-26

    The letter is an answer to a previous letter which appeared in the same journal and which was discrediting, according to the author of this letter, the Royal Commission on Contraception, Sterilization, and Abortion. The earlier letter refutes a quote from "Abortion and Social Justice" used by the Commission, regarding the situation in Colorado after rape became an indication for abortion. The quote reports that although between 1967-1971 the number of abortions for rape totalled 290, no rapist was charged or convicted for the crime. However, according to the author of this letter, the actual quote reads somewhat differently, and states that, during the same period, "no rapist was ever charged with his crime, much less convicted of it, which casts some real doubts on the reality of the alleged rapes." The meaning of this passage is that none of the alleged rapists had actually caused the 290 pregnancies. From records and government statistics it is possible to count about 3300 cases of rape known to the police in Colorado for the years 1967-1971. To suggest that none of these cases were charged or convicted is ridiculous. The author also states that rape as an indication for abortion will lead to abuse of the law, and that pregnancy for actual rape is rare.

    Abortion has been a reality in women's lives since the beginning of recorded history, typically with a high risk of fatal consequences, until the last century when evolutions in the field of medicine, including techniques of safe abortion and effective methods of family planning, could have ended the need to seek unsafe abortion. The context of women's lives globally is an important but often ignored variable, increasingly recognised in evolving human rights especially related to gender and reproduction. International and regional human rights instruments are being invoked where national laws result in violations of human rights such as health and life. The individual right to conscientious objection must be respected and better understood, and is not absolute. Health professional organisations have a role to play in clarifying responsibilities consistent with national laws and respecting reproductive rights. Seeking common ground using evidence rather than polarised opinion can assist the future focus. PMID:20303830

    Rhoden's article is one of three on "Abortion: searching for common ground" in this issue of the Hastings Center Report. Her article, together with those by M. Mahowald and M. Glendon, was prompted by the expectation that the impending U.S. Supreme Court decision in Webster v. Reproductive Health Services (3 July 1989) would overturn or restrict Roe v. Wade (1973). Rhoden, an advocate for the pro-choice position, asks whether a compromise leading to an acceptable regulatory policy is possible or desirable among those on opposite sides of the abortion issue. She identifies several reasons why the Roe decision is vulnerable to review, but argues that effective education about sexuality and comprehensive social support of women are better approaches to abortion than restrictive legislation.

    1990-08-01

    Amid the raging controversy on whether minors should have the same access to abortion as adults, the Connecticut legislature has passed a compromise statues that recognizes a minor's right seek an abortion, while imposing certain requirements. Those who seek to regulate access argue that because minors may lack the maturity to make a valid decision, parental notification is necessary; advocates of minors' right to access hold that it should be the minor who makes such personal decision. In an effort to resolve the conflict, Connecticut's law says that young women under the age of 16 must receive pregnancy-related information before an abortion can take place. Specifically., a physician or counselor is required to: 1) explain to the minor that the information provided is not intended to coerce or persuade her into making a particular choice; 2) explain that she may consider her decision any time prior to the operation or during the time period when abortion is legally permitted; 3) explain the alternatives of either carrying out the pregnancy or getting an abortion, including information on public and private agencies that may assist in carrying out the decision; 4) inform her that pubic and private agencies provide information on birth control; 5) discuss the possibility of involving the minor's parents(s), guardian(s), or other adult family member in the decision; and 6) allow the minor to ask questions and to obtain useful information. After the completion of the process, the minor must sign a form that attests that the requirements have been met, and -- if applicable -- that the minor has decided to involve a parent or relative. In cases where the health or safety of a minor requires and abortion, the Connecticut statute allows for the provisions to be waived.

When failures occurred, corrections and improvements were made to avoid a reoccurrence and to provide added capability for crew survival. Finally some lessons learned are summarized for future human launch vehicle designers to consider.

    This paper describes simulation and experimental results for a 1400A, {+-} 900V peak rated, switch mode power supply for SNS Injection Kicker Magnets. For each magnet (13 m{Omega}, 160{micro}H), the power supply must supply controlled pulses at 60 Hz repetition rate. The pulse current must rise from zero to maximum in less than 1 millisec in a controlled manner, flat top for up to 2 millisec, and should fall in a controlled manner to less than 4A within 500{micro}s. The low current performance during fall time is the biggest challenge in this power supply. The simulation results show that to meet the controlled fall of the current and the current ripple requirements, voltage loop bandwidth of at least 10 kHz and switching frequency of at least 100 kHz are required. To achieve high power high frequency switching with IGBT switches, a series connected topology with three phase shifted (O{sup o}, 60{sup o} & 120{sup o}) converters each with 40 kHz switching frequency (IGBT at 20kHz), has been achieved. In this paper, the circuit topology, relevant system specifications and experimental results that meet the requirements of the power supply are described in detail. A unique six pulse SCR rectifier circuit with capacitor storage has been implemented to achieve minimum pulse width to meet required performance during current fall time below 50A due to the very narrow pulse width and non-linearity from IGBT turn-on/off times.

    Polish laws specify the parties responsible for lawful medical care in the availability of abortion differently than the Resolution of the Council of Europe. According to Polish regulations they include all Polish doctors while according to the Resolution, the state. Polish rules should not discriminate against anyone in connection with his religion or belief, even more so because the issue of abortion is an example of an unresolved ethical dispute. The number of lawful abortion in Poland does not exceed 1000 per year and can be carried out by only a few specialists contracted by the National Health Fund. Sufficient information and assistance should be provided to all pregnant women by the National Health Fund. The participation of all physicians in the informing process is not necessary, as evidenced by the lack of complaints to provide information on where in vitro fertilization treatment can be found - until recently only available when paid for by the individual and performed in much larger numbers than abortion. Entities performing this paid procedure made sure to provide information on their own. The rejection of the right to the conscientious objection clause by negating the right to refuse information may lead some to give up the profession or cause the termination of certain professionals on the basis of the professed worldview. Meanwhile, doctors are not allowed to be discriminated against on the basis of their conscience or religion.

    2000-11-01

    Abortion is illegal in Brazil except when performed to save the woman's life or in cases of rape. This paper gives a brief history of parliamentary and extra-parliamentary efforts to change abortion-related legislation in Brazil in the past 60 years, the contents of some of the 53 bills that have been tabled in that time, the non-governmental stakeholders involved and the debate itself in recent decades. The authorities in Brazil have never assumed full public responsibility for reproductive health care or family planning, let alone legal abortion; the ambivalence of the medical profession is an important obstacle. Most politicians avoid getting involved in the abortion debate, but the majority of bills in the 1990s have favoured less restrictive legislation. Incremental legislative and health service changes could help to improve the situation for women. Advocacy is probably the most important action, to promote an environment conducive to change. Clandestine abortion is a serious public health problem in Brazil, and the inadequacy of family planning services is one of the causes of this problem. The solutions should be made a priority for the Brazilian public health system.

    1985-01-01

    At the same time that American women celebrate the freedoms won thus far for so many Americans, American women must realize they face some of the greatest threats to liberty in recent memory. To understand this movement against American women, it is necessary to first understand the roots of the historic movement for women's rights. Reproductive freedom for many years topped the agenda of the modern women's movement. At a time and in a land where rights were being enriched and liberty prized, choice took a prominent role, specifically, the right to abortion but also generally to repdocuctive freedom and the many underlying issues involved. This is why the various efforts to criminalize abortion effect every citizen, because they pose a serious threat to the constitutional rights of each individual. This is the intellectual view, or the "head" argument. The Constitution states that: "Congress shall make no laws respecting an establishment of religion, or prohibiting the free exercise thereof; the enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people; and no state shall make or enforce any laws which shall abridge the privileges or immunities of citizens of the US." Each of these clauses expresses the philosophy on which the Constitution was founded -- individual liberty. While there has been some legitimate disagreement over what constitutes an inalienable right, the concept is clear: the government should not become involved in personal philosophical or religious matters, except to permit the freedom of personal philosophical or religious expression. The anti-abortion contignent makes its case by claiming that a fertilized egg is a cona fide person and should, therefore, be guaranteed the Constitution's full roster of protections. In its landmark Roe v. Wade opinion, the Supreme Court held what pro-choice activities have been claiming for years. Since there is no empirical test by which measure

    Dundon, S

    1980-02-23

    Your editorial of Jan. 26 and the multi-signatory letter in your issue of Feb. 2 support the 1967 Abortion Act and suggest that Mr. Corrie's Bill is a retrograde step. The implication is that our professional knowledge should lead us to that conclusion. To take the opposite view risks being regarded as a member of a pressure group or a conscientious objector, but to remain silent might be construed as being in agreement. As I see it the great majority of people of varying ethnic groups, including those adhering to the Jewish, Muslim, and Christian faiths, subscribe to a behavioral code which regards human life as sacred: to take a life is to be countenanced only to save another. Abortion should be regarded as taking human life and morally wrong; making abortion legal does not make it morally right. Doctors are in a very difficult position, and cannot, no more than politicians can, make moral decisions for other people. Traditionally, however, the profession has a role in the responsibility for protection of life, and perhaps the public have a right to expect this protection. Human life begins at conception and some human rights begin at this time. Life (and its protection) seems to be a most basic right. The World Medical Association, in the Declaration of Oslo (1970), stated: "1. The first moral principle imposed upon the doctor is respect for human life as expressed in a clause of the Declaration of Geneva: 'I will maintain the utmost respect for human life from the time of conception.'" The 1967 Abortion Act did not result from a general referendum, much less a medical referendum. If the Corrie Bill is passed and abortions are cut by 2/3 as you suggest, this would, in my view, be a step, not back, but in the right direction.

  7. Abortion a business hurdle for nation's Catholic hospitals.

    PubMed

    Burda, D

    1989-08-25

    Abortion is the foremost moral issue for 626 Catholic hospitals nationwide since church teachings prohibit the performance of elective abortions. This and the fact that Catholic hospitals can not do voluntary sterilizations can hinder their ability to get managed care contracts. In some cases a hospital will not join a network because abortions and sterilizations are done in other hospitals in the network. In other cases they have been in plans where abortions are performed in other contract facilities; this does not violate the Catholic church policy since the abortions are not performed in their facility. When a Catholic and secular hospital plan a merger, Catholic ideals seem to take precedence. A Catholic hospital that went bankrupt in Philadelphia, was turned over to investors, and was under no obligation to follow the Catholic church's directives, but did not perform abortions anyway. In Washington state there are merger talks going on between a secular facility and the Franciscan Health System. The cessation of abortion and sterilization services appear to be outweighed by the financial benefits. Besides, these procedures can be performed through other providers in the area. In Michigan similar merger talks may fail because of the abortion issue. The government justice system is investigating and is likely to challenge any merger there.

    Abstract Objective To determine the location of Canadian abortion services relative to where reproductive-age women reside, and the characteristics of abortion facilities and providers. Design An international survey was adapted for Canadian relevance. Public sources and professional networks were used to identify facilities. The bilingual survey was distributed by mail and e-mail from July to November 2013. Setting Canada. Participants A total of 94 abortion facilities were identified. Main outcome measures The number and location of services were compared with the distribution of reproductive-age women by location of residence. Results We identified 94 Canadian facilities providing abortion in 2012, with 48.9% in Quebec. The response rate was 83.0% (78 of 94). Facilities in every jurisdiction with services responded. In Quebec and British Columbia abortion services are nearly equally present in large urban centres and rural locations throughout the provinces; in other Canadian provinces services are chiefly located in large urban areas. No abortion services were identified in Prince Edward Island. Respondents reported provision of 75 650 abortions in 2012 (including 4.0% by medical abortion). Canadian facilities reported minimal or no harassment, in stark contrast to American facilities that responded to the same survey. Conclusion Access to abortion services varies by region across Canada. Services are not equitably distributed in relation to the regions where reproductive-age women reside. British Columbia and Quebec have demonstrated effective strategies to address disparities. Health policy and service improvements have the potential to address current abortion access inequity in Canada. These measures include improved access to mifepristone for medical abortion; provincial policies to support abortion services; routine abortion training within family medicine residency programs; and increasing the scope of practice for nurses and midwives to include abortion

    The complications accompanying the various methods of abortion as studied in different surveys are reported. In studies of dilation and curettage (D and C) and vaccuum aspiration (VA), lethality ranges from .5 to 2.9 deaths/100,000 cases. Metrorrhagia occurred in 2.5-6% of the D and C cases studied and in 2.9-3.5% of the VA cases. The bleeding was accompanied by infection in most cases where abortive tissue remained in the uterus, which occured in .4-.8% of the D and C cases and in .6-.9% of the VA cases studied. Postabortive bleeding occurred through the 10th day in up to 25% of the patients and was related to the length of the gestation period before abortion. Pelvic infection, mostly of the endometrium, occurred in about 1.4% of the D and C patients and in .3-1.2% of the VA patients. 1.4% of the D and C patients and .6% of the VA patients experienced a rise in body temperature as the only complication of abortion. Perforation of the uterus occurred in about .8% of the D and C patients and in .1-.6% of VA patients. Lesions of the cervix had to be sutured in .1% of the D and C group and .3% of the VA group. Saline instillation, used for abortions in the second trimest er, had a mortality rate of about 20/100,000 cases. Since the success rate of saline instillation is 90-98%, complications are more frequent, often requiring treatment with oxytocin or curettage. Extensive bleeding occurred in 2.3-4%. Curettage of the placenta was required in about 2.1-16.9% of the cases. Pelvic inflammation occurred in about 2.5% and temperature elevation in 1-3.4%. Abdominal hysterotomies had a lethality of 208/100,000. Pelvic hemorrhage occurred in 31%, inflammation in 4.7%, temperature elevation in 13%, and febrile reactions in 31% of the abdominal hysterotomies studied. It is necessary to establish international definitions of abortion complications for better documentation, and postoperative observations should be recorded more conscientiously. PMID:1251502

    The PEP-II RF systems incorporate numerous feedback loops in the low-level processing for impedance control and operating point regulation. The interaction of the multiple loops with the beam is complicated, and the systems incorporate online diagnostic tools to configure the feedback loops as well as to record fault files in the case of an RF abort. Rapid and consistent analysis of the RF-related beam aborts and other failures is critical to the reliable operation of the B-Factory, especially at the recently achieved high beam currents. Procedures and algorithms used to extract diagnostic information from time domain fault files are presented and illustrated via example interpretations of PEP-II fault file data. Example faults presented will highlight the subtle interpretation required to determine the root cause. Some such examples are: abort kicker firing asynchronously, klystron and cavity arcs, beam loss leading to longitudinal instability, tuner read back jumps and poorly configured low-level RF feedback loop.

    2000-09-25

    An all solid-state kicker pulser for a high current induction accelerator (the Dual-Axis Radiographic Hydrodynamic Test facility DARHT-2) has been designed and fabricated. This kicker pulser uses multiple solid state modulators stacked in an inductive-adder configuration. Each modulator is comprised of multiple metal-oxide-semiconductor field-effect transistors (MOSFETs) which quickly switch the energy storage capacitors across a magnetic induction core. Metglas is used as the core material to minimize loss. Voltage from each modulator is inductively added by a voltage summing stalk and delivered to a 50 ohm output cable. A lumped element circuit model of the inductive adder has been developed to optimize the performance of the pulser. Results for several stalk geometries will be compared with experimental data.

    An effect induced by parasitic inductance in a pulsed power supply for a fast extraction kicker was studied. The parasitic inductance in high voltage capacitors for a low impedance pulse forming network disturbs a sharp rise of an excitation current. A high voltage capacitor with a coaxial structure to minimize the parasitic inductance is proposed. The effectiveness was confirmed experimentally. An impedance mismatch by a leakage inductance of a pulse transformer in a transmission line was studied. The effect is serious at the flat-top period of the excitation current. By introducing a compensation circuit, which is composed by a capacitor and a resistor, impedance matching was established. The pulsed power supply for the fast extraction kicker was operated at a charging voltage of 30 kV. A required rise time of less than 1.1 μs was achieved. The flatness was also confirmed to be in an acceptable value of less than 1%.

    Surveys dealing with abortion in Latin America have provided useful information despite problems in the collection and use of the data. Considerations that should be taken into account in designing abortion surveys and using the resultant information have been discussed here. Special attention has been paid to the need for a broad definition of "abortion" in order to overcome difficulties in gathering information about abortion in Latin America. Surveys have shown increasing incidence of abortion throughout Latin America in the recent past. In examining changes over time it is crucial to interpret clearly and carefully the summary measures of proportion of pregnancies ending in abortion and abortion rates per 1,000 women. It is also important to realize that the level and direction of change of the abortion rate depends on both the rate at which women are becoming pregnant and the proportion of pregnancies ending in abortion. Better survey design and techniques and more careful use of the resulting information will aid in the planning and evaluation of programs aimed at reducing abortion in Latin America. PMID:960180

    Voluntarily induced abortion has been under permanent dispute and legal regulations, because societies invariably condemn extramarital pregnancies. In recent decades, a measure of societal tolerance has led to decriminalize and legalize abortion in accordance with one of two models: a more restricted and conservative model known as therapeutic abortion, and the model that accepts voluntary abortion within the first trimester of pregnancy. Liberalization of abortion aims at ending clandestine abortions and decriminalizes the practice in order to increase reproductive education and accessibility of contraceptive methods, dissuade women from interrupting their pregnancy and, ultimately, make abortion a medically safe procedure within the boundaries of the law, inspired by efforts to reduce the incidence of this practice. The current legal initiative to decriminalize abortion in Chile proposes a notably rigid set of indications which would not resolve the three main objectives that need to be considered: 1) Establish the legal framework of abortion; 2) Contribute to reduce social unrest; 3) Solve the public health issue of clandestine, illegal abortions. Debate must urgently be opened to include alternatives in line with the general tendency to respect women's decision within the first trimester of pregnancy.

    This study examines the association between religion and attitudes toward the practice of abortion and abortion policy in Brazil. Drawing upon data from the 2002 Brazilian Social Research Survey (BSRS), we test a number of hypotheses with regard to the role of religion on opposition to the practice of abortion and its legalization. Findings indicate that frequently attending Pentecostals demonstrate the strongest opposition to the practice of abortion and both frequently attending Pentecostals and Catholics demonstrate the strongest opposition to its legalization. Additional religious factors, such as a commitment to biblical literalism, were also found to be significantly associated with opposition to both abortion issues. Ultimately, the findings have implications for the future of public policy on abortion and other contentious social issues in Brazil.

  16. The Politicization of Abortion and the Evolution of Abortion Counseling

    PubMed Central

    2013-01-01

    The field of abortion counseling originated in the abortion rights movement of the 1970s. During its evolution to the present day, it has faced significant challenges, primarily arising from the increasing politicization and stigmatization of abortion since legalization. Abortion counseling has been affected not only by the imposition of antiabortion statutes, but also by the changing needs of patients who have come of age in a very different era than when this occupation was first developed. One major innovation—head and heart counseling—departs in significant ways from previous conventions of the field and illustrates the complex and changing political meanings of abortion and therefore the challenges to abortion providers in the years following Roe v Wade.

    Doane, B K; Quigley, B G

    1981-09-01

    A search of the literature on the psychiatric aspects of abortion revealed poor study design, a lack of clear criteria for decisions for or against abortion, poor definition of psychologic symptoms experienced by patients, absence of control groups in clinical studies, and indecisiveness and uncritical attitudes in writers from various disciplines. A review of the sequelae of therapeutic abortion revealed that although the data are vague, symptoms of depression were reported most frequently, whereas those of psychosis were rare. Positive emotional responses and a favourable attitude toward therapeutic abortion were often reported, although again the statistical bases for these reports were inadequate. There was a lack of evidence that the reported effects were due to having an abortion rather than to other variables.Other areas dealt with inadequately in most of the articles reviewed included analyses of symptoms and of the evidence on the duration of sequelae, descriptions of the criteria for approving abortions, investigation of the psychiatric histories of the patients, presentation of data on the effects of refusing abortion requests, systematic study of a number of epidemiologic factors, and analyses of the circumstances leading to pregnancy in patients having abortions. The evidence was found to be sparse on the effects of supportive relationships, different abortion techniques and the length of gestation on the psychologic status of patients. Little attention was paid to the consequences of psychiatric labelling of patients, or to the effect of having an abortion on factors that may influence future pregnancies.The potential roles of health care professionals appear to deserve more study, and little research seems to have been done to compare the psychologic factors associated with abortion and those associated with live birth. As well, there is little evidence that differences in abortion legislation account for significant differences in the psychologic

    On January 27 and 28, 1989 a workshop and a meeting were organized in Paris by Mouvement Francais pour le Planning Familial (MFPF/France) and the IPPF Europe Region. The workshop was held on the first day. 24 staff and volunteers from Planned Parenthood Associations of 15 countries attended, reviewing abortion laws, the definition of therapeutic abortion, and the incidence and problems of second trimester abortion. Second trimester abortion is available in only a few European countries. Second trimester abortions are rare in France (about 2000 per annum), and in 1986 1717 French women travelled to England in order to seek an abortion. All late abortions are performed for serious reasons. Older women may mistake signs of pregnancy for the onset of the menopause; and women fearful of social or familial punishment, especially teenagers, may be reluctant to consult a doctor. The experiences of Denmark and Sweden, where the problem is partially solved, suggest some strategies: optimize accessibility of contraceptive services, particularly for women at higher risk of late abortion; diminish the taboo surrounding abortion, so that women are less frightened to seek help at an early stage of pregnancy; make abortion services available in all regions of the country; avert time-consuming enforced waiting periods or consent for minors; and stimulate public information campaigns on the importance of seeking help early. On January 28 a meeting involving about 200 participants took place at the Universite Paris Dauphine, Salle Raymond Aron. Speakers at the meeting discussed the issue of late abortion in Europe, the difficulties of obtaining late abortions, counseling, medical problems, the woman's point of view, and possible solutions. At the close of the meeting, the MFPF called on the French government to modify some of the articles in the Penal Code that restrict women's access to safe and legal abortion.

    Economic hardship accompanying large recessions can lead families to terminate unplanned pregnancies. To assess whether abortions have risen during the recession, we collected crude abortion data from 2000 to 2012 from Eurostat for countries that had legal abortions and complete data. Declining trends in abortion ratios between 2000 and 2009 have been reversing. Excess abortions between 2010 and 2012 totaled 10.6 abortions per 1000 pregnancies ending in abortion or birth or 6701 additional abortions (95% CI 1190–9240) with stronger effects in younger ages. Economic shocks may increase recourse to abortion. Further research should explore causal pathways and protective factors. PMID:27009038

    The NO?A Experiment will construct a detector optimized for electron neutrino detection in the existing NuMI neutrino beam. The NuMI beam line is capable of operating at 400 kW of primary beam power and the upgrade will allow up to 700 kW. Ceramic beam tubes are utilized in numerous kicker magnets in different accelerator rings at Fermi National Accelerator Laboratory. Kovar flanges are brazed onto each beam tube end, since kovar and high alumina ceramic have similar expansion curves. The tube, kovar flange, end piece, and braze foil alloy brazing material are stacked in the furnace and then brazed. The most challenging aspect of fabricating kicker magnets in recent years have been making hermetic vacuum seals on the braze joints between the ceramic and flange. Numerous process variables can influence the robustness of conventional metal/ceramic brazing processes. The ceramic-filler metal interface is normally the weak layer when failure does not occur within the ceramic. Differences between active brazing filler metal and the moly-manganese process will be discussed along with the applicable results of these techniques used for Fermilab production kicker tubes.

    Medicaments are used to prepare for instrument abortions in the 1st trimester and as inducers of abortion in the 2nd trimester. The effects, side effects, and dangers depend on the substances used and the route of application, which can be vaginal, cervical, injection, instillation, extraamniotic, intraamniotic, intravenous, or intramuscular. In the past, intraamniotic instillation of a 20% salt solution was the most common 2nd trimester method in Japan, the US, and Eastern Europe, giving a success rate of 90%. Serious side effects prompted substitution of extraamniotic instillation, which rarely produces serious side effects. Instillation of a 60% urea solution into the amniotic fluid in combination with oxytocin or prostaglandin produces an abortion in 13-21 hours, with a failure rate of 3% and a frequency of cervical laceration of under 1%. Extraamniotic use of a .1% solution of rivanol yields a success rate of about 85%, with a relatively long average time to explusion of 24-41 hours. In case of failure the procedure can be repeated. The advantage of the Rivanol method is the rarity of infectious complications. Alcohol is not used as a human abortifacient because it produces necrosis in the decidua and placenta. Prostaglandins are used in most 2nd trimester abortions. Research is underway to identify derivatives that will have an extended uterine impact without serious side effects. Different routes of administration have different effectiveness rates and dangers. All prostaglandins cause side effects including pain during uterine contractions, gastro-intestinal reactions, nausea, vomiting, fever, and headaches. Specific preparations are associated with other effects, some of them life-threatening. Emergency treatment should be available when these substances are used. Adjuvant measures may be employed before adminstration of an abortifacient agent to soften the cervix, or after administration to hasten the procedure. The choice of procedure depends upon the

    The development of new and safer manned space vehicles is a top priority at NASA. Recently two different approaches of how to accomplish this mission of keeping astronauts safe was successfully demonstrated. With work already underway on an Apollo-like launch abort system for the Orion Crew Exploration Vehicle (CEV), an alternative design concept named the Max Launch Abort System, or MLAS, was developed as a parallel effort. The Orion system, managed by the Constellation office, is based on the design of a single solid launch abort motor in a tower positioned above the capsule. The MLAS design takes a different approach placing the solid launch abort motor underneath the capsule. This effort was led by the NASA Engineering and Safety Center (NESC). Both escape systems were designed with the Ares I Rocket as the launch vehicle and had the same primary requirement to safely propel a crew module away from any emergency event either on the launch pad or during accent. Beyond these two parameters, there was little else in common between the two projects, except that they both concluded in successful launches that will further promote the development of crew launch abort systems. A comparison of these projects from the standpoint of technical requirements; program management and flight test objectives will be done to highlight the synergistic lessons learned by two engineers who worked on each program. This comparison will demonstrate how the scope of the project architecture and management involvement in innovation should be tailored to meet the specific needs of the system under development.

  3. Abortion for fetal abnormality.

    Maclean, N E

    I wish to thank Dr. Pauline Bennett for her reply (NZ Med J, 13 June). She has demonstrated well that in dealing with sensitive difficult issues such as abortion for fetal abnormality, the one thing the doctor is not recommended to do is to speak the truth] I am prompted to write this letter for 2 reasons. Firstly, the excellent letter written by Dr. A. M. Rutherford (NZ Med J, 13 June) on the subject of abortion stated, "The most disturbing feature about the whole controversy is the 'blunting of our conscience'." When the doctors are not encouraged to be honest with patients then indeed our conscience has been blunted. Secondly, I watched Holocaust last night, and cannot refrain from stating that I see frightening parallels between our liberal abortion policy and the activities of the Nazis. As I watched the "mental patients" being herded into the shed for gassing by the polite, tidy, white coated medical staff, and then heard the compassionate, sensitive, letter of the hospital authorities to the relatives of the deceased, the parallel became obvious. The mental patients were weak, defenseless, burdensome, and uneconomic; the unborn are weak, defenseless, burdensome, and uneconomic. The hospital authority's letter was acceptable in many ways, acceptable except that its words bore no relation to the truth. It is said that the "first casualty of war is the truth". Whether that war involves the Jews, or the insane, or the unborn, the statement would seem correct.

  4. Public funding of abortions and abortion counseling for poor women.

    PubMed

    1997-01-01

    This essay seeks to reveal the weakness in arguments against public funding of abortions and abortion counseling in the US based on economic, ethico-religious, anti-racist, and logical-consistency objections and to show that public funding of abortion is strongly supported by appeals to basic human rights, to freedom of speech, to informed consent, to protection from great harm, to justice, and to equal protection under the law. The first part of the article presents the case against public funding with detailed considerations of the economic argument, the ethico/religious argument, the argument that such funding supports racist genocide or eugenic quality control, and arguments that a logical inconsistency exists between the principles used to justify the legalization of abortions and arguments for public funding. The second part of the article presents the case for public funding by discussing the spending of public funds on morally offensive programs, arguments for public funding of abortion counseling for the poor, and arguments for public funding of abortions for the poor. It is concluded that it is morally unacceptable and rationally unjustifiable to refuse to expend public funds for abortions for low income women, because after all most money for legal abortions for the poor comes from welfare payments made to women. If conservative forces want to insure that no public funds pay for abortions, they must stop all welfare payments to pregnant women. PMID:12348330

    Across four decades of political and social action, Nepal changed from a country strongly enforcing oppressive abortion restrictions, causing many poor women's long imprisonment and high rates of abortion-related maternal mortality, into a modern democracy with a liberal abortion law. The medical and public health communities supported women's rights activists in invoking legal principles of equality and non-discrimination as a basis for change. Legislative reform of the criminal ban in 2002 and the adoption of an Interim Constitution recognizing women's reproductive rights as fundamental rights in 2007 inspired the Supreme Court in 2009 to rule that denial of women's access to abortion services because of poverty violated their constitutional rights. The government must now provide services under criteria for access without charge, and services must be decentralized to promote equitable access. A strong legal foundation now exists for progress in social justice to broaden abortion access and reduce abortion stigma. PMID:24890742

  6. Dworkin and Casey on abortion.

    PubMed

    Stroud, Sarah

    1996-01-01

    This article responds to two important recent treatments of abortion rights. I will mainly discuss Ronald Dworkin's recent writings concerning abortion: his article "Unenumerated rights: whether and how Roe should be overruled," and his book Life's Dominion. In these writings Dworkin presents a novel view of what the constitutional and moral argument surronding abortion is really about. Both debates actually turn, he argues, on the question of how to interpret the widely shared idea that human life is sacred. At the heart of the abortion debate is the essentially religious notion that human life has value which transcends its value to any particular person; abortion is therefore at bottom a religious issue. Dworkin hopes to use this analysis to show that the religion clauses of the First Amendment provide a "textual home" for a woman's right to choose abortion. I wish to scrutinize this suggestion here; I want to probe the precise consequences for abortion rights of such an understanding of their basis. I will argue that the consequences are more radical than Dworkin seems to realize. The other work I will examine here is the important 1992 Supreme Court decision on abortion, Planned Parenthood v. Casey. The controlling opinion in that case, written jointly by Justices Kennedy, O'Connor, and Souter, strongly reaffirmed Roe v. Wade, but also upheld most of the provisions of a Pennsylvania statute that had mandated various restrictions on abortion. The justices' basis for upholding these restictions was their introduction of a new constitutional standard for abortion regulations, an apparently weaker standard than those that had governed previous Supreme Court abortion decisions. I think there is a flaw in Casey's new constitutional test for abortion regulations, and I will explain, when we turn to Casey, what it is and why it bears a close relation to Dworkin's reluctance to carry his argument as far as it seems to go.

  7. Abortion in a just society.

    PubMed

    Hunt, M E

    1993-01-01

    A female Catholic theologian imagines a just society that does not judge women who decide to undergo an abortion. The Church, practitioners, and the courts must trust that women do make person-enhancing choices about the quality of life. In the last 15 years most progress in securing a woman's right to abortion has been limited to white, well-educated, and middle or upper middle class women. A just society would consider reproductive options a human right. Abortion providers are examples of a move to a just society; they are committed to women's well-being. There are some facts that make one pessimistic about achieving abortion in a just society. The US Supreme Court plans to review important decisions establishing abortion as a civil right. Further, some men insist on suing women who want to make their own reproductive decisions--an anti-choice tactic to wear away women's right to reproductive choice. Bombings of abortion clinics and harassment campaigns by anti-choice groups are common. These behaviors strain pro-choice proponents emotionally, psychically, and spiritually. Their tactics often lead to theologians practicing self-censorship because they fear backlash. Abortion providers also do this. Further, the reaction to AIDS is that sex is bad. Anti-abortion groups use AIDS to further their campaigns, claiming that AIDS is a punishment for sex. Strategies working towards abortion in a just society should be education and persuasion of policymakers and citizens about women's right to choose, since they are the ones most affected by abortion. Moreover, only women can secure their rights to abortion. In a just society, every health maintenance organization, insurance company, and group practice would consider abortion a normal service. A just society provides for the survival needs of the most marginalized.

    At the same time that American women celebrate the freedoms won thus far for so many Americans, American women must realize they face some of the greatest threats to liberty in recent memory. To understand this movement against American women, it is necessary to first understand the roots of the historic movement for women's rights. Reproductive freedom for many years topped the agenda of the modern women's movement. At a time and in a land where rights were being enriched and liberty prized, choice took a prominent role, specifically, the right to abortion but also generally to repdocuctive freedom and the many underlying issues involved. This is why the various efforts to criminalize abortion effect every citizen, because they pose a serious threat to the constitutional rights of each individual. This is the intellectual view, or the "head" argument. The Constitution states that: "Congress shall make no laws respecting an establishment of religion, or prohibiting the free exercise thereof; the enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people; and no state shall make or enforce any laws which shall abridge the privileges or immunities of citizens of the US." Each of these clauses expresses the philosophy on which the Constitution was founded -- individual liberty. While there has been some legitimate disagreement over what constitutes an inalienable right, the concept is clear: the government should not become involved in personal philosophical or religious matters, except to permit the freedom of personal philosophical or religious expression. The anti-abortion contignent makes its case by claiming that a fertilized egg is a cona fide person and should, therefore, be guaranteed the Constitution's full roster of protections. In its landmark Roe v. Wade opinion, the Supreme Court held what pro-choice activities have been claiming for years. Since there is no empirical test by which measure

Warren situates the Webster decision in a larger context of 19th and 20th century American anti-abortion legislation, the Court's 1973 Roe decision and its predecessors, and the anti-abortion campaign that followed Roe. She then discusses Webster and its legal, practical, and political implications, concluding that the future of legal abortion in the United States is radically uncertain.

    1994-01-01

    National politics in the US, Poland, and Ireland have in recent years been afire with debate over abortion. Conflicting abortion laws almost scuttled the reunification of Germany. This paper describes how the abortion debate took hold in post-Communist Poland and how the issue came to be so entrenched in US politics in the wake of the US Supreme Court's 1973 decision on abortion in the case of Roe vs. Wade. It focuses upon abortion mainly as a method of birth control which women have always sought when needed regardless of the procedure's legal status. The controversies and campaigns recorded and the ideas offered focus upon women's access to affordable, safe, and legal abortion. The author argues that Poland is no place to be a woman and presents sections on the country's church, government, and medical profession; Roe vs. Wade; who opposes abortion rights and their broad success; the 1992 US presidential election; Bill Clinton's presidency; why the abortion debate has been different in Britain; and new issues on abortion.

    1984-11-15

    Opinion is divided as to the advisability of routine use of prophylactic antibiotics for curettage abortion. Six studies, including three randomized clinical trials, suggest that prophylaxis reduces infectious morbidity associated with curettage abortions by about one half. Three other studies, two involving prophylaxis for instillation abortions and one involving a vaginal antiseptic for curettage abortion, support the hypothesis that antimicrobial prophylaxis reduces morbidity. Tetracyclines are commonly used for this purpose. The cost of routine prophylaxis even with an expensive tetracycline would appear to be offset by the savings in direct and indirect costs. Prophylaxis may help prevent both short-term morbidity and potential late sequelae, such as ectopic pregnancy and infertility.

    The controversy surrounding the question of public financing of Medicaid abortions in the U.S. was fanned through 5 separate court decisions in January 1980. In 3 of the decisions--directed against the Connecticut, Minnesota, and Missouri Medicaid abortion programs--the courts invalidated the state laws on the grounds that they limited federal funding of abortions for poor women too narrowly. Another decision stated that the Missouri law violated the equal protection clause of th Constitution. A decision in the U.S. District Court in Brooklyn, New York, stated that the 1976 Hyde amendment's restrictions on federal payment for abortions under Medicaid are unconstitutional. Each case is briefly analyzed.

  15. The medicolegal aspects of abortion.

    There was little demand for abortion in the 19th century. There was no population explosion and large families were needed to tend the farm. People were more religious; women were 2nd class citizens; and abortions in those days were medically unsafe. The movement to reform abortion laws in the United States stemmed largely from 3 events in the early 1960s: 1) the request in 1963 of Sherri Finkbine for an abortion after she had taken thalidomide and then learned of its teratogenic potential; 2) a rubella epidemic in 1964 and 1965; and 3) the 1965 Supreme Court decision declaring the Connecticut birth control law to be unconstitutional. In 1970 abortion was completely legalized in the states of Hawaii, Alaska, New York and Washington -- the first 3 by legislation and the last by popular referendum. With 4 states operating under repeal laws, 12 under reform laws, and 34 under restrictive laws, the current practice of abortion in the U.S. at this time is chaotic. In order to cope with the tremendous new demand for abortions, doctors have had to learn new techniques and hospitals have had to modify their procedures and adapt their facilities. An obstacle in the transition to universally available abortion has been the resistance of attending physicians, house staff, paramedical personnel, and hospital administrators and trustees. The legal future of abortion lies more in the courts than in the legislatures. With the impetus provided by the 4 new repeal laws, other states will now revise their abortion statutes at an accelerated pace, but it will not be possible to achieve universal repeal by this state-by-state route. Medical practitioners need to prepare for the eventuality of legalized abortion on a national scale.

    Family planning counseling and the provision of postabortion contraception should be an integrated part of abortion and postabortion care to help women avoid another unplanned pregnancy and a repeat abortion. Postabortion contraception is significantly more effective in preventing repeat unintended pregnancy and abortion when it is provided before women leave the healthcare facility where they received abortion care, and when the chosen method is a long-acting reversible contraceptive (LARC) method. This article provides evidence supporting these two critical aspects of postabortion contraception. It suggests that gynecologists and obstetricians have an ethical obligation to do everything necessary to ensure that postabortion contraception, with a focus on LARC methods, becomes an integral part of abortion and postabortion care, in line with the recommendations of the International Federation of Gynecology and Obstetrics and of several other organizations.

    Background Factors such as poverty, stigma, lack of knowledge about the legal status of abortion, and geographical distance from a provider may prevent women from accessing safe abortion services, even where abortion is legal. Data on the consequences of abortion denial outside of the US, however, are scarce. Methods In this article we present data from studies among women seeking legal abortion services in four countries (Colombia, Nepal, South Africa and Tunisia) to assess sociodemographic characteristics of legal abortion seekers, as well as the frequency and reasons that women are denied abortion care. Results The proportion of women denied abortion services and the reasons for which they were denied varied widely by country. In Colombia, 2% of women surveyed did not receive the abortions they were seeking; in South Africa, 45% of women did not receive abortions on the day they were seeking abortion services. In both Tunisia and Nepal, 26% of women were denied their wanted abortions. Conclusions The denial of legal abortion services may have serious consequences for women's health and wellbeing. Additional evidence on the risk factors for presenting later in pregnancy, predictors of seeking unsafe illegal abortion, and the health consequences of illegal abortion and childbirth after an unwanted pregnancy is needed. Such data would assist the development of programmes and policies aimed at increasing access to and utilisation of safe abortion services where abortion is legal, and harm reduction models for women who are unable to access legal abortion services.

  18. Herbal infusions used for induced abortion.

    PubMed

    Ciganda, Carmen; Laborde, Amalia

    2003-01-01

    Plants and herbs have been used to induce abortions but there is very little published information describing the commonly used ones. The purpose of this report is to describe the herbal products used to induce abortions, and to enhance awareness and understanding of their toxic effects. A descriptive retrospective survey was conducted on the calls received by the Montevideo Poison Centre between 1986 and 1999 concerning the ingestion of herbal infusions with abortive intent. A total of 86 cases involving 30 different plant species were identified. The species most frequently involved were ruda (Ruta chalepensis/graveolens), cola de quirquincho (Lycopodium saururus), parsley (Petroselinum hortense), and an over-the-counter herbal product named Carachipita. The components of Carachipita are pennyroyal (Mentha pulegium), yerba de la perdiz (Margiricarpus pinnatus), oregano (Origanum vulgare), and guaycuri (Statice brasiliensis). Abortion occurred in 23 cases after the ingestion of parsley, ruda, Carachipita, celery, Cedron, francisco alvarez, floripon, espina colorada. Out of the 23 cases, 15 involved the only the ingestion of plants, 4 cases used injected drugs (presumably hormones), and in 4 cases there was associated self-inflicted instrumental manipulation. Multiple organ system failure occurred in those patients who had ingested ruda (alone or in combination with parsley or fennel), Carachipita, arnica, or bardana. Deaths occurred in one case of Carachipita ingestion and in 4 cases of ruda ingestion (2 cases of ruda alone, 2 cases of ruda with parsley and fennel). Self-inflicted instrumental manipulations were found in 4 of the patients with multiple organ system failure and in one of those who died. The results of this report are not conclusive, but it appears that the ingestion of plants to induce abortion involves the risk of severe morbidity and mortality.

    The first flight test of the Orion Abort Flight Test project is scheduled to launch in Spring 2010. This flight test is known as Pad Abort 1 (PA-1) and it is intended to accomplish a series of flight test objectives, including demonstrating the capability of the Launch Abort System (LAS) to propel the Crew Module (CM) to a safe distance from a launch vehicle during a pad abort. The PA-1 Flight Test Article (FTA) is actively controlled by a guidance, navigation, and control (GN&C) system for much of its flight. The purpose of this paper is to describe the design, development, and analysis of the PA-1 GN&C system. A description of the technical solutions that were developed to meet the challenge of satisfying many competing requirements is presented. A historical perspective of how the Orion LAV compares to the Apollo Launch Escape Vehicle (LEV) design will also be included.

    We conducted a retrospective cohort study using randomly selected medical charts of women reporting a history of partner violence and women with no history of partner violence at the time of a family planning or abortion appointment (n = 6,564 per group). We analyzed lifetime history of partner violence for odds of lifetime history of abortion and miscarriage number, and birth control problems. To more closely match timing, we analyzed a subsample of 2,186 women reporting current violence versus not at the time of an abortion appointment for differences in gestational age, medical versus surgical method choice, and return for follow-up visit. After adjusting for years at risk and demographic characteristics, women with a past history of partner violence were not more likely to have ever had one abortion, but they were more likely to have had problems with birth control, repeat abortions, and miscarriages than women with no history of violence. Women with current partner violence were also more likely to be receiving an abortion at a later gestational age. We found no differences between the groups in return for abortion follow-up visit or choice of surgical versus medication abortion. Findings support screening for the influence of partner violence on reproductive health and related safety planning. PMID:24580133

  4. Abortion: epidemiology, safety, and technique.

    In 1991, the abortion literature was characterized by articles relating to 1) epidemiologic issues in abortion care, 2) advances in knowledge and experience with medical abortifacients such as mifepristone (RU 486), and 3) cervical ripening prior to abortion with the use of both mifepristone and prostaglandins. Technical methods of achieving termination of pregnancy continue to be similar in the United States, the United Kingdom, and Europe, although induction-abortion times are generally slower in Europe than in the United States. Surgically, dilatation and evacuation procedures continue to be more common in the United States than in other countries. The effectiveness of mifepristone is undisputed, and the recommended dose for early first-trimester termination is being compared with lower dose alternative regimens. There is additional evidence that at least in the short term, the negative psychological sequelae of abortion are infrequent and are inconsequential as a public health issue. PMID:1504270

    2015-06-01

    What role does birth play in the debate about elective abortion? Does the wrongness of infanticide imply the wrongness of late-term abortion? In this paper, I argue that the same or similar factors that make birth morally significant with regard to abortion make meaningful viability morally significant due to the relatively arbitrary time of birth. I do this by considering the positions of Mary Anne Warren and José Luis Bermúdez who argue that birth is significant enough that the wrongness of infanticide does not imply the wrongness of late-term abortion. On the basis of the relatively arbitrary timing of birth, I argue that meaningful viability is the point at which elective abortion is prima facie morally wrong.

  6. [Induced abortion: a world perspective].

    PubMed

    Henshaw, S K

    1987-01-01

    This article presents current estimates of the number, rate, and proportion of abortions for all countries which make such data available. 76% of the world's population lives in countries where induced abortion is legal at least for health reasons. Abortion is legal in almost all developed countries. Most developing countries have some laws against abortion, but it is permitted at least for health reasons in the countries of 67% of the developing world's population. The other 33%--over 1 billion persons--reside mainly in subSaharan Africa, Latin America, and the most orthodox Muslim countries. By the beginning of the 20th century, abortion had been made illegal in most of the world, with rules in Africa, Asia, and Latin America similar to those in Europe and North America. Abortion legislation began to change first in a few industrialized countries prior to World War II and in Japan in 1948. Socialist European countries made abortion legal in the first trimester in the 1950s, and most of the industrialized world followed suit in the 1960s and 1970s. The worldwide trend toward relaxed abortion restrictions continues today, with governments giving varying reasons for the changes. Nearly 33 million legal abortions are estimated to be performed annually in the world, with 14 million of them in China and 11 million in the USSR. The estimated total rises to 40-60 million when illegal abortions added. On a worldwide basis some 37-55 abortions are estimated to occur for each 1000 women aged 15-44 years. There are probably 24-32 abortions per 100 pregnancies. The USSR has the highest abortion rate among developed countries, 181/1000 women aged 15-44, followed by Rumania with 91/1000, many of them illegal. The large number of abortions in some countries is due to scarcity of modern contraception. Among developing countries, China apparently has the highest rate, 62/1000 women aged 15-44. Cuba's rate is 59/1000. It is very difficult to calculate abortion rates in countries

    In Slovenia abortion will continue to be available during the first 10 weeks of pregnancy as it has been since 1978. The Slovenian Constitutional Court passed this decision in December, 1991 calling the right to abortion a basic human right. T he ruling was a setback both for the government's conservative parties and the Catholic church. In Croatia, where the Catholic church is campaigning against abortion, the situation is quite different. Zagreb is full of stickers and posters with anti-abortion messages branding abortion murder and spreading inaccurate information in announcements. In 1990, there were 56,000 abortions. For every child that was born, one was aborted. The largest Croatian newspaper publicizes the Catholic view. They want pro-choice women of the volunteer group Tresnjevka to stop their struggle. The church and conservative women's groups press for inclusion of abortion in the Constitution. They are very powerful, and the fear is that might soon succeed in restricting or outlawing abortion. Tresnjevka is making efforts to organize a coordination and information center for women in Zagreb where there are 350,000 women and children refugees. Informative brochures are printed on natural healing methods in gynecology, as drugs are very scarce, and addresses for gynecological emergency care are also provided. Abortion has been legally available on demand during the 1st 10 weeks of pregnancy since 1978. Fore year Tresnjevka has worked for women, trying to raise funds from personal donations and from the government for their activities. Funds from foreign countries have never been received. At present many of the group's activities are on hold because of lack of funds, nevertheless the determination to continue fighting is alive. PMID:12285925

    Morgenthau, J E

    The issue of abortion, except when it is rendered moot because the fetus endangers the life of the mother, is not really a medical issue. The physician's role is to help patients achieve and maintain their maximum potential for physical, mental, and social well-being. To accomplish this, the physician must acquire a constantly evolving database of scientific knowledge, must evaluate this information in a critical and ethical manner, and must be prepared to apply what is learned. In the realm of applied ethics, no particular religion, profession, culture, class, or sex should be thought of as having all the answers in the realm of applied ethics. This physician's actions are predicated on the belief that, to a large extent, ethical precepts reflect the broader social and economic issues of the period in which they are articulated. If this is the case, then in today's world the population explosion, the postindustrial society, the women's rights movement, inequality of access, and the ability to perform prenatal diagnosis are all factors which have molded the approach to the issue of abortion. Only the last 3 of these can in any way be considered as medical. When considering the role of a physician in dealing with the issue of abortion in the adolescent, this individual relies on the concept articulated by the World Health Association (WHA): promoting the physical, emotional, and social well-being of one's patients. Each year in the US over 1 million 15-19 year olds become pregnant, resulting in over 600,000 births. Most of these pregnancies are unintentional, yet approximately 90% of the infants are kept in the home by mothers who are ill prepared to be parents. What is most disturbing is that the pregnancy rate for the younger mother, 16 years or under, is accounting for an ever increasing percentage of the total. Studies at the Adolescent Health Center of the Mount Sinai Hospital in New York City as well as national studies suggest that the younger teens are more

    During the ascent flight phase of NASA s Constellation Program, the Ares launch vehicle propels the Orion crew vehicle to an agreed to insertion target. If a failure occurs at any point in time during ascent then a system must be in place to abort the mission and return the crew to a safe landing with a high probability of success. To achieve continuous abort coverage one of two sets of effectors is used. Either the Launch Abort System (LAS), consisting of the Attitude Control Motor (ACM) and the Abort Motor (AM), or the Service Module (SM), consisting of SM Orion Main Engine (OME), Auxiliary (Aux) Jets, and Reaction Control System (RCS) jets, is used. The LAS effectors are used for aborts from liftoff through the first 30 seconds of second stage flight. The SM effectors are used from that point through Main Engine Cutoff (MECO). There are two distinct sets of Guidance and Control (G&C) algorithms that are designed to maximize the performance of these abort effectors. This paper will outline the necessary inputs to the G&C subsystem, the preliminary design of the G&C algorithms, the ability of the algorithms to predict what abort modes are achievable, and the resulting success of the abort system. Abort success will be measured against the Preliminary Design Review (PDR) abort performance metrics and overall performance will be reported. Finally, potential improvements to the G&C design will be discussed.

    The ILC damping ring injection and extraction kickers will require high availability modulators that can deliver {+-}5 kV pulses into 50 {Omega} with a 2 ns flattop ({approx}1 ns rise and fall time) at up to 6 MHz. An effort is underway at SLAC National Accelerator Laboratory to meet these requirements using a transmission line adder topology to combine the output of an array of {approx}1 kV modules. The modules employ an ultra-fast hybrid MOSFET/driver that can switch 33 A in 1.2 ns. Experimental results for a scale adder structure are presented.

  11. Abortion reporting in the United States: an examination of the federal-state partnership.

    PubMed

    Saul, R

    1998-01-01

    In the US, lack of data on abortions has been increasingly recognized as a problem because it 1) frustrates debate about abortion procedures, late-term abortions, and the incidence and timing of abortions; 2) challenges the accurate establishment of a baseline for states to use when seeking new federal grants that reward decreases in abortion rates; and 3) will hinder documentation of a shift to earlier, drug-induced abortions. Criticism of the data collection efforts of the Centers for Disease Control (CDC), however, ignores the fact that states have an independent responsibility for data collection and submission. Exploration of this topic begins by providing background information on the history of the US vital statistics system. Next, the collection of abortion data is traced from its origins in the 1960s with a consideration of the controversial nature of such reporting as well as of the impact of lack of data completeness and quality. The analysis continues with a review of the current state of abortion reporting that looks at laws, regulations, voluntary reporting, state data collection, and national data collection. The discussion concludes that a national abortion data collection system is largely in place but that variability among states affects the CDC's ability to accurately assess the data or to answer specific questions about abortion in the US. Policy-makers should match information needs with resources and investigate the limits of the current systems and data quality to improve state-level data collection and management.

    To study the reasons for the postponement of abortion, an orally administered survey was conducted which compared 200 women who had first-trimester abortions with 200 women requiring saline induction. In 1 of 4 patients studied, the health care system was responsible for the delay. Environmental factors and some personality factors seem to be responsible for the delay. Basic sexual education might prevent some of the delay.

    Smoking habits have been compared in three samples of pregnancies: (1) spontaneous abortions (n = 610); (2) induced abortions (n = 800); and (3) deliveries (n = 1337). The variables studied were, besides smoking habits, day of LMP, outcome of earlier pregnancies, maternal age, and, for the delivery sample, also diagnoses of mother and child, gestational length, sex, and birthweight. A statistical analysis of the association between smoking and the risk of having a spontaneous abortion was made. The comparisons were made with all types of intra-uterine pregnancies but spontaneous abortions, e.g., deliveries and induced abortions. The effects and consequences of that are discussed. The smoking rates according to pregnancy outcome differ among the samples. In the induced abortion sample 58% smoked compared with 50% in the spontaneous abortion sample and 44% in the delivery sample. The well-known effect of smoking on gestational length and birthweight was shown. No significant effect of smoking on the miscarriage risk was seen. The only trend was the opposite. Possible explanations for this are discussed.

  14. Republic of Ireland: abortion controversy.

    PubMed

    1998-01-01

    The problems associated with illegal abortion dominate public discussion in Ireland. While abortion is illegal in Ireland, the Supreme Court directed in 1992 that Irish women can go to Britain for abortions when their lives are thought to be at risk. Abortion was a constant feature during the Irish Presidential election campaign in October, while a dispute about the future of a 13-year-old girl's pregnancy dominated the headlines in November. The presidential election on October 30 resulted in a victory for one of the two openly anti-choice candidates, Mary McAleese, a lawyer from Northern Ireland. With a voter turnout of 47.6%, McAleese polled 45.2% of the votes cast. Although the president may refuse to sign bills which have been passed by parliament, McAleese has said that she will sign whatever bill is placed before her, even if it liberalizes abortion law in the republic. As for the case of the 13-year-old pregnant girl, she was taken into the care of Irish health authority officials once the case was reported to the police. However, the health board, as a state agency, is prevented by Irish law from helping anyone travel abroad for abortion. The girl was eventually given leave in a judgement by a High Court Judicial Review on November 28 to travel to England for an abortion.

    2014-08-01

    I argue that it is possible for prospective mothers to wrong prospective fathers by bearing their child; and that lifting paternal liability for child support does not correct the wrong inflicted to fathers. It is therefore sometimes wrong for prospective mothers to bear a child, or so I argue here. I show that my argument for considering the legitimate interests of prospective fathers is not a unique exception to an obvious right to procreate. It is, rather, part of a growing consensus that procreation can be morally problematic and that generally talking of rights in this context might not be warranted. Finally, I argue that giving up a right to procreate does not imply nor suggest giving up on women's absolute right to abort, which I defend.

  1. [Umberto Eco and abortion].

    PubMed

    1997-09-01

    The Cardinal of Milan and the linguist and writer Umberto Eco maintained a correspondence in the mid-1990s in connection with the Italian magazine ¿Liberal¿. One of the issues discussed was the conflict between belief in the value of human life and existing abortion legislation. Umberto Eco stated that he would do all in his power to dissuade a woman pregnant with his child from having an abortion, regardless of the personal cost to the parents, because the birth of a child is a miracle.

    1997-09-01

    The Cardinal of Milan and the linguist and writer Umberto Eco maintained a correspondence in the mid-1990s in connection with the Italian magazine ¿Liberal¿. One of the issues discussed was the conflict between belief in the value of human life and existing abortion legislation. Umberto Eco stated that he would do all in his power to dissuade a woman pregnant with his child from having an abortion, regardless of the personal cost to the parents, because the birth of a child is a miracle. He would not, however, feel capable of imposing his ethical position on anyone else. Terrible moments occur in which women have a right to make autonomous decisions concerning their bodies, their feelings, their futures.

  3. Psychological sequelae of induced abortion.

    1989-12-01

    This article reviews the scientific literature on the psychological sequelae of induced abortion. The methodology and results of studies carried out over the last twenty-two years are examined critically. The unanimous consensus is that abortion does not cause deleterious psychological effects. Women most likely to show subsequent problems are those who were pressured into the operation against their own wishes, either by relatives or because their pregnancy had medical or foetal contraindications. Legislation which restricts abortion causes problems for women with unwanted pregnancies and their doctors. It is also unjust, as it adversely most affects lower socio-economic class women.

    Although Cambodia now permits elective abortion, scarcity of research on this topic means that information on abortion incidence is limited to regional estimates. This estimation model combines national survey data from Demographic and Health Surveys (DHS) with national prospective data of abortion procedures from government health facilities, collected in 2005 and 2010, to calculate the national incidence of safe and unsafe abortion. According to DHS, the proportion of all induced abortions that took place in a health facility in the five years preceding each survey increased from almost 52% to 60%. Projecting from facility-based abortions to national estimates, the national abortion rate increased from 21 to 28 per 1000 women aged 15-44. The abortion ratio also increased from 19 to 28 per 100 live births. This research quantifies an increase in safely induced abortions in Cambodia and provides a deeper understanding of induced abortion trends in Cambodia.

    Ceramic chambers will be used in the pulsed kicker magnets for the injection of H{sup -} into the US Spallation Neutron Source (SNS) accumulator ring. There are two reasons for using ceramic chambers in kickers: (1) to avoid shielding of a fast-changing external magnetic field by metallic chamber walls; and (2) to reduce heating due to eddy currents. The inner surfaces of the ceramic chambers will be coated with a conductive layer, possibly titanium (Ti) or copper with a titanium nitride (TiN) overlayer, to reduce the beam coupling impedance and provide passage for beam image current. This paper describes the development of sputtering method for the 0.83m long 16cm inner diameter ceramic chambers. Coatings of Ti, Cu and TiN with thicknesses up to 10 {micro}m were produced by means of DC magnetron sputtering. The difficulty of coating insulators was overcome with the introduction of an anode screen. Films with good adhesion, uniform longitudinal thickness, and conductivity were produced.

    1996-04-01

    The debate regarding the practice and role of abortion has been an enduring and problematic area of discourse within the nursing literature, with a tendency towards a polarized and inevitably simplistic analysis of what, for many practitioners, women and families, remains a highly complex and morally fraught concept. This paper attempts to explore the concept of abortion from within a feminist epistemology, to present a review of the literature as regards women's reproductive health and responsibilities, and thereby to contribute to the process of better understanding the role of abortion within contemporary health care practice. In order to facilitate the study it has been necessary to explore the wide spectrum of historical, philosophical, legal, moral and political imperatives pertaining to the meaning of abortion as represented within contemporary society, not only in relation to women and their reproductive health, but to feminism, women's well-being and self-determinism per se.

    I discuss three topics. First, there is a philosophical connecting thread between several recent trends in the abortion discussion, namely, the issue of our animal nature, and physical embodiment. The philosophical name given to the position that you and I are essentially human animals is "animalism." In Section II of this paper, I argue that animalism provides a unifying theme to recent discussions of abortion. In Section III, I discuss what we do not find among recent trends in the abortion discussion, namely "the right to privacy." I suggest some reasons why the right to privacy is conspicuous by its absence. Finally, I address Patrick Lee's claim that the evil of abortion involves "the moral deterioration that the act brings to those who are complicit in it, and to the culture that fosters it."

    Doctors for a Woman's Choice on Abortion would agree with 1 point in Lord Denning's ruling on the role of nurses in abortions induced by (PGS) prostaglandins (November 15, p. 1091). The nurse should not be doing a doctor's job, as Lord Denning indicated, and we sympathize with any nurse who is doing so (though the 1967 Abortion Act allows any nurse to abstain, on grounds of conscience). However, the ruling that nurses are not legally covered to participate in any way with the "procuring of a miscarriage" (using terminology of the 1861 Offenses against the Persons Act upon which the ruling is based) does not require a radical change in the practice of late abortions (constituting only 7% of the terminations) or any change in the law. PG abortion can be done without a nurse. With the extraamniotic technique, a very cheap pump can be used to give subsequent doses of the PG (a function normally performed by a nurse) through the catheter left inserted through the cervix after the 1st dose has been given by the doctor. Alternatively, the intraamniotic method can be used, where PG is instilled into the amniotic sac via a needle passed through the abdominal wall. This normally requires only 1 dose, given by the doctor. Rarely are subsequent doses needed; however they could be given by the doctor with very little addition to his or her workload. While the fact that PG abortion can be done without nurses is not realized, late abortion will be restricted, a situation which is entirely deplorable. Also deplorable are the comments of an antiabortion nature made by Lord Denning, over and above the legal ruling in his jurisdiction to make. His ruling, furthermore, seems to have been sufficiently confused for the Department of Health to withdraw its circular on abortion and await an interpretation before issuing another. PMID:6107800

    1998-06-01

    Reported, in this article, are the cases of two young women who developed endogenous Candida endophthalmitis after induced abortion. Both women experienced transient fever, chills, and abdominal pain after the abortion and were given antibiotics. The diagnosis of endophthalmitis was established on the basis of typical fundus appearance, positive vaginal culture, and (in one case) positive vitreous culture. In the first woman, who received vitrectomy and intravitreal amphotericin B injection, the affected eye had a best corrected visual acuity of 20/200. In the second woman, who was given systemic corticosteroid treatment before the correct diagnosis was reached, recurrent retinal detachment developed and the best corrected visual acuity was counting fingers. It appears that Candida organisms harbored in the genital tract are directly inoculated into the venous system during induced abortion. Once in the blood, if sufficient fungal load is present, Candida albicans tends to localize in the choroid and to spread toward the retina and vitreous cavity. The immunosuppressive effect of corticosteroids further increases the risk of endophthalmitis. PMID:9645729

    1984-01-01

    At this time a rather large number of congenital abnormalities still occur. About 2-3% of pregnancies will result in children with major congenital abnormalities that cannot be detected prenatally. Yet, with the availability of prenatal diagnosis for an ever increasing number of genetic problems and, more recently, for developmental problems as well, a new option was offered to couples at risk when they took the risk of pregnancy: finding out whether the fetus was abnormal. An early argument regarding the ethics of this option was formulated by Dan Callahan, director of the Hastings Institute for Ethics, Society and the Life Sciences, when he indicated the need to be careful about the term "option." A need exists to be careful about societal pressures in favor of the new medical options--on, for example, a pregnant woman who is over 35 and does not get a prenatal diagnosis; or on a woman carrying a Down's syndrome child identified by prenatal diagnosis not to have an abortion. This was the 1st specter raised when prenatal diagnosis was introduced. The most common indication for amniocentesis is the risk of chromosomal abnormalities. The risk of discovering a chromosomal abnormality by amniocentesis is about double the risk at birth because a number of chromosomally abnormal fetuses are lost late in the 2nd trimester by spontaneous abortion. The age cutoff at 35 raises an immediate ethical question: since the total number of births to women over age 35 seems to be increasing, and at the same time a greater and greater percentage of children with Down's syndrome are born to women under age 35, the question arises as to whether amniocentesis should be done on all pregnancies, and whether all births with Down's syndrome should be selectively aborted or avoided. Amniocentesis in all pregnancies is impractical at this time from the technological and the cost perspective, but the ethical question should be raised. Among the X-linked disorders, 1 group cannot be

    Complications of induced abortion sadly remain significant causes of maternal mortality and morbidity around the world, but only in countries that do not provide access to safe abortion services. This article presents a brief account of how high maternal mortality from induced abortion became history in the UK and the dire consequences to women's health that unsafe abortion still has in many countries of the world. It gives a brief overview of the methods available to evacuate the uterus, with particular reference to manual vacuum aspiration. The status of the law in different countries is discussed, together with the need for health professionals to interpret repressive laws in ways that enables them to care for women who seek their help. Safe abortion services are cost effective, essential services for women. Men are part and parcel of the reason women resort to terminating a pregnancy, and, together with the countless children whose lives are dependent on a healthy caring mother, are also beneficiaries of safe abortion services. There can be no excuse for continuing to deny these services to so many women around the world.

    Abortion is a social problem and criminal sanctions are very ineffective in limiting it and are seldom applied (133 legal actions vs. 65,600 cases of induced abortion in 1965). Abortion is a social disease, as are prostitution, juvenile delinquency, drug abuse, and so far has been an insoluble problem. Colombian laws should be modified to reflect reality. Sex education must be emphasized, because ignorance is one of the main causes of abortion. Leniency should be applied toward women who cooperate with the authorities in identifying the person who performed an abortion. Legalization of abortion and enforcement of strict laws against it are considered as possible solutions, but both are rejected. The former is regarded as morally unacceptable and as imposing an excessive burden on scarce health services, the latter as even worse, imposing an equivalent burden on the court system, without s olving either health or social problems. The best and probably only solution is to improve education in family planning, to promote knowledge and motivation to enable the population to make sound and responsible decisions. PMID:4804875

    This report presents the major findings of a study of induced abortion in Nepal, based on 165 cases out of the 1,576 female patients identified as having abortion-related complications who were admitted to five major hospitals in urban Nepal during a one-year study period. Traditional birth attendants had been the service providers for two-fifths of the women. A longer delay in hospital referrals and lengthier hospital stays occurred for cases of induced abortion than for those of spontaneous abortion. Twelve of the 165 women in the study died in the hospital, most of them from tetanus. Deaths resulting from abortion-related complications represented more than half of all maternity-related deaths in the hospitals studied. The authors suggest that health risks could be reduced considerably by strengthening the hospital-referral system and by taking some preventive steps, such as educating the traditional birth attendants and other paramedical providers about the consequences of unsafe abortion practices; increasing the availability of contraceptive methods; and promoting the use of menstrual regulation, which has recently become available in Nepal on a limited scale, mostly in private clinics.

    Medical abortion is a method of pregnancy termination that by its nature enables more active involvement of women in the process of managing, and sometimes even administering the medications for, their abortions. This qualitative evidence synthesis reviewed the global evidence on experiences with, preferences for, and concerns about greater self-management of medical abortion with lesser health professional involvement. We focused on qualitative research from multiple perspectives on women's experiences of self-management of first trimester medical abortion (<12weeks gestation). We included research from both legal and legally-restricted contexts whether medical abortion was accessed through formal or informal systems. A review team of four identified 36 studies meeting inclusion criteria, extracted data from these studies, and synthesized review findings. Review findings were organized under the following themes: general perceptions of self-management, preparation for self-management, logistical considerations, issues of choice and control, and meaning and experience. The synthesis highlights that the qualitative evidence base is still small, but that the available evidence points to the overall acceptability of self-administration of medical abortion. We highlight particular considerations when offering self-management options, and identify key areas for future research. Further qualitative research is needed to strengthen this important evidence base.

  18. Abortion restrictions may undermine welfare reform.

    PubMed

    1999-02-01

    Results from a study conducted by Pennsylvania State University's Population Research Institute indicate that more restrictive abortion laws in the US may have led to an increase in the number of single mothers, even given new welfare reform laws which make unmarried childbearing more costly. Study findings are based upon county rates of female-headed families from the 1980 and 1990 censuses, excluding those in Alaska and Hawaii. By making unmarried childbearing more costly, welfare reform has sparked a demand for abortion, while at the same time abortion laws have restricted access to abortion. An increasing number of unmarried women on welfare have therefore chosen childbearing over abortion. The study found a decline in the number of abortions in counties where abortion laws had become more strict. That states can now require abortion providers to notify the parents of minors who have abortions, to restrict Medicaid funding for abortions, and to establish 24-hour waiting periods has made abortion either a difficult or impossible option for some women. These restrictive abortion laws and geographic barriers to abortion have discouraged women from undergoing the procedure, increasing the number of female-headed families and single mothers. The public policy goal of reducing unmarried childbearing and female-headed families is being undermined by the growing geographic and legal barriers designed to discourage abortion. PMID:12348920

    This study aims to describe factors associated with the number of past abortions obtained by New York City (NYC) abortion patients in 2010. We calculated rates of first and repeat abortion by age, race/ethnicity, and neighborhood-level poverty and the mean number of self-reported past abortions by age, race/ethnicity, neighborhood-level poverty, number of living children, education, payment method, marital status, and nativity. We used negative binomial regression to predict number of past abortions by patient characteristics. Of the 76,614 abortions reported for NYC residents in 2010, 57% were repeat abortions. Repeat abortions comprised >50% of total abortions among the majority of sociodemographic groups we examined. Overall, mean number of past abortions was 1.3. Mean number of past abortions was higher for women aged 30-34 years (1.77), women with ≥5 children (2.50), and black non-Hispanic women (1.52). After multivariable regression, age, race/ethnicity, and number of children were the strongest predictors of number of past abortions. This analysis demonstrates that, although socioeconomic disparities exist, all abortion patients are at high risk for repeat unintended pregnancy and abortion. PMID:25779755

    Launch vehicle ascent is a time of high risk for an onboard crew. There is a large fraction of possible failures for which time is of the essence and a successful abort is possible if the detection and action happens quickly enough. This paper focuses on abort determination based on data already available from the Guidance, Navigation, and Control system. This work is the result of failure analysis efforts performed during the Ares I launch vehicle development program. The two primary areas of focus are the derivation of abort triggers to ensure that abort occurs as quickly as possible when needed, but that false aborts are avoided, and evaluation of success in aborting off the failing launch vehicle.

    PubMed

    Blinken, A J

    1991-01-01

    As Europe edges toward some sort of unity, the volatile abortion debate has begun to spill across national boundaries. Reflecting the continent's religious and cultural diversity, abortion laws throughout Europe vary widely. Holland and Sweden have the most liberal abortion laws. The former allows abortion on demand, while the later permits abortion until the 18th week -- and possibly up until term, if the National Health Bureau gives permission. Britain, France, and Belgium have also adopted liberal abortion laws. Other nations, however, have more conservative laws. Since 1983, Ireland has banned abortion entirely. Spain allows abortion only in cases of rape, malformed fetuses, or when the mother's life is in danger. Many countries are also experiencing bitter debates over abortion. Czechoslovakia's liberal abortion law has come under increasing pressure, and in Poland, bishops and legislators have feuded over the legality of abortion. The move towards unification has only intensified these debates. Germany is currently without a national abortion law, as the former East Germany still enjoys a more liberal abortion law than West Germany. Differences over abortion laws have led to what is know in Europe as abortion shipping. Every year, an estimated 15,000 Irish women travel to England, some 7,000 German women go to Holland, and some 3,000 French women travel to England -- all seeking to take advantage of another country's abortion law. Some Europeans have begun to look for continent-wide laws on abortion. Recently, an Irish group argued against its country's law before the European court of Justice. Right-to-life groups have also fought to establish continent-wide restrictions. So far, it seems unlikely that Europe will reach an agreement on the issue of abortion.

  2. Contemporary issues for spontaneous abortion. Does recurrent abortion exist?

    PubMed

    Reindollar, R H

    2000-09-01

    Most of the time, spontaneous abortion is a random event and represents the natural selection process. Although a recurrent factor may be present and may cause one or more abortions for a given couple, such instances are rare. Well-substantiated causes include parental chromosomal abnormalities (e.g., translocation), antiphospholipid syndrome, PCOD, and maternal age greater than 40 years. Müllerian duplication defects are most likely a cause of pregnancy loss for some women. A growing body of evidence refutes the role of corpus luteum defect as a common cause of recurrent abortion. Other causes are numerically infrequent in occurrence. It is likely that cigarette smoking and alcohol consumption contribute to pregnancy wastage. Although some therapies for the causes listed herein have been proven effective by randomized controlled trials, most have not. Given the excellent outcome demonstrated for most couples with unexplained recurrent abortion in the absence of treatment, it is difficult to recommend unproven therapies, especially if they are invasive and expensive. Instead of examining the environment in which pregnancy has occurred or been planned, clinicians have simply counted the number of spontaneous abortions among couples in an attempt to determine who should be evaluated. The former approach would seem most appropriate and proactive.

  3. Abortion epidemic in Latin America.

    1983-05-01

    Recent surveys have shown that 3.4 million illegal abortions may be taking place in the Latin American countries every year, with a rate of around 45/1000 women of childbearing age. Yet only in Cuba can women have abortion on demand. In the other countries the penalty for the abortionist and the client is a prison sentence. The only way of measuring the frequency of abortion is through the numbers of women entering hospitals for treatment of postabortion complication, but not all countries publish hospitals statistics that are reliable. Surveys in Chile and Colombia for 1974 show a rate of 11.7-17.9/1000 women of fertile age undergoing illegal abortions, with only 1/3 resulting in complications. The law is not strictly enforced in these countries because the number of people that will have to be prosecuted is too large and because there is no place to care for the young children of women who will be prosecuted. Yet the abortion death rate (38% of total maternal deaths) is so high that a new policy must be drawn up, especially since women who have normal deliveries are sent home earlier to make room for those with abortion complications, resulting in a high infant mortality rate. In addition the rate of pregnancies among adolescents is very high due to the permissive social atmosphere combined with a lack of sex education in the schools. Studies that would allow international comparisons to show ways to prevent the consequences of illegal abortions are needed.

  4. [Readers' position against induced abortion].

    PubMed

    1981-08-25

    Replies to the request by the Journal of Nursing on readers' positions against induced abortion indicate there is a definite personal position against induced abortion and the assistance in this procedure. Some writers expressed an emotional "no" against induced abortion. Many quoted arguments from the literature, such as a medical dictionary definition as "a premeditated criminally induced abortion." The largest group of writers quoted from the Bible, the tenor always being: "God made man, he made us with his hands; we have no right to make the decision." People with other philosophies also objected. Theosophical viewpoint considers reincarnation and the law of cause and effect (karma). This philosophy holds that induced abortion impedes the appearance of a reincarnated being. The fundamental question in the abortion problem is, "can the fetus be considered a human life?" The German anatomist Professor E. Bleckschmidt points out that from conception there is human life, hence the fertilized cell can only develop into a human being and is not merely a piece of tissue. Professional nursing interpretation is that nursing action directed towards killing of a human being (unborn child) is against the nature and the essence of the nursing profession. A different opinion states that a nurse cares for patients who have decided for the operation. The nurse doesn't judge but respects the individual's decision. Some proabortion viewpoints considered the endangering of the mother's life by the unborn child, and the case of rape. With the arguments against abortion the question arises how to help the woman with unwanted pregnancy. Psychological counseling is emphasized as well as responsible and careful assistance. Referral to the Society for Protection of the Unborn Child (VBOK) is considered as well as other agencies. Further reader comments on this subject are solicited. PMID:6913282

    Pooled literatures showed that the induced abortion in China faces many problems:the number of induced abortion remains large; most cases are young and nulliparity women; the frequency of abortion is high; and the interval between one and another abortion is short. Health promotion strategies should be applied to address these problems. It is important to increase the population's awareness of contraception,especially among nulliparity and migrant populations. Routine and effective contraceptive methods should be recommended and emphasized during induced abortion and delivery to lower the rate of induced abortion.

    The article reports upon the characteristics of 300 abortion applicants in Arkansas manifesting significant stress from unwanted pregnancy between May 1, 1970 and June 30, 1971. The sample is limited by the fact that all of these women had been willing to seek medical aid. Patients ranged from ages 13-47, 131 of them ages 17-21. 35% had had some college education; another 29% were high school graduates. 50.6%, 20.6%, and 27.3% were single, divorced, and married, respectively. 59.6% of the patients were primiparas. 18.3%, 9.6%, and 12.3% were classified as being neurotic, having psychophysiologic tendencies (gastrointestinal problems, obesity, chronic headaches), and having sociopathic features (passive-aggressive, frankly rebellious, delinquent, antisocial, alcoholic), respectively. 12 women had noticeable schizoid features; 4 women had mildly active schizophrenia. Fathers of the women were usually blue-collar workers (55.3%) or white-collar workers (24.6%). The most frequent ordinal sibling position among the women was oldest child (38%). Parental instability (1 or both parents lost through death, divorce, father usually away working, chronic alcoholism, etc.) was reported by 39.6% of the patients. Patients' attitudes toward the unwanted pregnancy included dislike of inexpediency of the situation (82.6%), self-depreciation (55.6%), and aversion (28.6%). Precipitated psychiatric disorders were for the greatest part mild. Manifesting symptoms included depression (66.7%), anxiety (21%), and mixed anxiety and depression (12.2%). Suicidal threats and gestures were made by 22 and 8 patients, respectively. In summary, the study reveals a group of predominantly Caucasian women from unstable, middle-class urban families who were going through an adjustment reaction to adolescence or adult life.

  7. Abortion and the law: the Supreme Court, privacy, and abortion.

    Marsh, F H

    1997-01-01

    This article examines the impact of the continuing politicization of the abortion issue in the US on the rights of women and on the emerging concept of fetal rights. The introduction 1) attributes the "final and total politicization" of a woman's right to control her reproduction to the "undue burden" standard introduced by the Supreme Court in its 1992 Casey decision and 2) claims that, if unchecked, the concept of fetal rights may give the state's interest in protecting potential life supremacy over women's rights. The next section presents an in-depth discussion of the politicization of the right to abortion that covers such topics as how the courts before Casey became the forum for debating abortion policy, how the "undue burden" standard fails to set definite parameters of acceptable state behavior, how the Casey decision in effect abandons the trimester-based framework of reference provided in Roe vs. Wade, how Casey allows states to subtly coerce women seeking abortions, how the Casey decision failed to reduce the intense politicization of abortion, and how the court failed to protect individual rights to health care and abortion funding from states. Part 3 of the article begins its exploration of the concept of "fetal rights" with a sketch of the history of this concept in the US courts starting in 1884 when damages for miscarriage were denied. Ways in which fetal rights compete with the rights of a pregnant woman are described, the Supreme Court is blamed for allowing states to develop this concept, and issues of patient confidentiality versus reporting requirements are considered. It is concluded that the Supreme Court will have to act to limit fetal rights.

  8. Effects of providing advance cues during a soccer penalty kick on the kicker's rate of success.

    The effect of explicitly providing goalkeeper's movement advanced cue to the kicker during a real penalty kick task was assessed. 32 expert soccer players (M age= 23.2 yr.), who were divided into four groups: an experimental group, a discovery group, a placebo group, and a control group, participated. Rate of success in the task was assessed, as well as goals, decision times, and ball flight times. Providing an advance cue significantly improved the players' rate of success relative to players without the advance cue; this difference was still present after 1 and 7 days without training. The experimental group adapted better to the time range within which the response could be effective, while the discovery group showed adaptations. Explicit instructions about the advance cues available from goalkeepers' actions before the dive during practice can improve penalty kick performance.

    This paper describes the pulse modulator power supplies used to drive the kicker magnets that inject the muon beam into the 8-2 storage ring that has been built at Brookhaven National Laboratory. Three modulators built into coaxial structures consisting of a series circuit of an energy storage capacitor, a damping resistor and a fast thyratron switch are used to energize three magnets that kick the beam into the proper orbit. A 100 kV charging power supply is used to charge the capacitor to 95kV. The damping resistor shapes the magnet current waveform to a 450 nanosecond half-sine to match the injection requirements. This paper discusses the modulator design, construction and operation.

    Background In Papua New Guinea abortion is restricted under the Criminal Code Act. While safe abortions should available in certain situations, frequently they are not available to the majority of women. Sepsis from unsafe abortion is a leading cause of maternal mortality. Our findings form part of a wider, mixed methods study designed to identify complications requiring hospital treatment for post abortion care and to explore the circumstances surrounding unsafe abortion. Methods Through a six month prospective study we identified all women presenting to the Eastern Highlands Provincial Hospital following spontaneous and induced abortions. We undertook semi-structured interviews with women and reviewed individual case notes, extracting demographic and clinical information. Findings Case notes were reviewed for 56% (67/119) of women presenting for post abortion care. At least 24% (28/119) of these admissions were due to induced abortion. Women presenting following induced abortions were significantly more likely to be younger, single, in education at the time of the abortion and report that the baby was unplanned and unwanted, compared to those reporting spontaneous abortion. Obtained illegally, misoprostol was the method most frequently used to end the pregnancy. Physical and mechanical means and traditional herbs were also widely reported. Conclusion In a country with a low contraceptive prevalence rate and high unmet need for family planning, all reproductive age women need access to contraceptive information and services to avoid, postpone or space pregnancies. In the absence of this, women are resorting to unsafe means to end an unwanted pregnancy, putting their lives at risk and putting an increased strain on an already struggling health system. Women in this setting need access to safe, effective means of abortion. PMID:25329982

    Horellou-lafarge, C

    1982-01-01

    This article examines the process by which the control and suppression of abortion shifted from the judicial domain to become an object of medical control in France. Abortion was a crime under the Napoleonic Code of 1810 and remained severely punishable for a century, but the law was regarded as too severe and prosecution was lax. The prescribed punishments became less stringent in 1923 but were later toughened again. Laws against abortion did not seem fair to much of the population concerned or to many of those charged with enforcing the laws, and they did not seem to uphold any inviolable moral principle. Increasing discontent with existing abortion laws, which were felt no longer to reflect the needs or mores of the society, and moreover to penalize poor women, who could not afford medically safe abortions abroad, and a belief that the law was doing nothing to reduce the numbers of abortions were among the stimuli that prompted the search for improved legislation. The public debate about the revised abortion law and the proper role of physicians and magistrates in determing access to abortion are traced though an exposition of opinions and quotations of the major participants in the controversy. The law of 1975 removed abortion from the control of magistrates and thereby liberalized access to it, but by entrusting access to abortion to the medical profession, the law embodied a bias toward preventing abortion. New social forces were behind the 1975 law, including pressure from women's groups which were developing a new consciousness of their rights and place in society, and a new role of medical practitioners, who occupy a privileged position in a social system based on knowledge rather than property. The new law still regards abortion as an evil and attempts to discourage it by imposing numerous constraints concerning when, where, and by whom it can be performed, by not requiring health personnel or facilities to make abortion available and by limiting the

    This paper covers the simulation and evaluation of a controller design for the Crew Module (CM) Launch Abort System (LAS), to measure its ability to meet the abort performance requirements. The controller used in this study is a hybrid design, including features developed by the Government and the Contractor. Testing is done using two separate 6-degree-of-freedom (DOF) computer simulation implementations of the LAS/CM throughout the ascent trajectory: 1) executing a series of abort simulations along a nominal trajectory for the nominal LAS/CM system; and 2) using a series of Monte Carlo runs with perturbed initial flight conditions and perturbed system parameters. The performance of the controller is evaluated against a set of criteria, which is based upon the current functional requirements of the LAS. Preliminary analysis indicates that the performance of the present controller meets (with the exception of a few cases) the evaluation criteria mentioned above.

    The protection of the RHIC experimental detectors from damage due to beam hitting close upstream elements in cases of abort kicker prefires requires some dedicated precautionary measures with two general options: to bring the beam close to a limiting aperture (i.e. the beam pipe wall), as far upstream of the detector components as possible or, alternatively, to bring a limiting aperture close to the circulating beam. Spontaneous and random prefires of abort kicker modules (Pulse Forming Network, PFN) have a history as long as RHIC is being operated. The abort system consist of 5 kickers in per ring, each of them equipped with its own dedicated PFN.

    In ancient Assyria, fathers held the right of life or death over their newborn infants, but women found to have performed an abortion on themselves or others were impaled and denied burial. This punishment was otherwise reserved for crimes against the state such as high treason or assault on the king. Likewise, in Babylon if a wife arranged her husband's death so that she could marry another man, she was convicted of treason and impaled or crucified. Thus, ancient thought paralleled the husband-wife relationship with that of the state-subject. The small group of men who generally dominate institutions such as the state, the church, or a corporation have a primary demand for obedience and deference to their supreme authority from their underlings. These groups did not condemn abortion because it involved questions of life or death. After all, many states have permitted infanticide, many still sanction execution, and all are willing to sacrifice the lives of their soldiers in war. Patriarchs condemn abortion because they consider it treasonous for a woman to assert the right to use her own judgement and to treat her body as if it were her own and not the property of her husband. This denies the supremacy of the male, which is the first principle of patriarchs. Because patriarchal institutions depend upon the subjection of women, women's bodies become important markers in the struggle for human freedom. This explains why patriarchal institutions in the US have continuously attacked women's right to abortion by fragmenting the statute allowing abortion and attempting to render the fragments illegal. While US women have won other rights that can be protected legally, women require the right to abortion in order to possess the right to physical integrity and to be able to undo what men have done to them. Otherwise, men would be able to create a set-back in women's human rights by forcing women into motherhood.

    Findings of a multicenter study that was discussed during the 1993 Health Ministers' Conference showed that about 30% of maternal deaths in east, central, and southern Africa were associated with complications of unsafe abortion. The Commonwealth Regional Health Community Secretariat in collaboration with the Support for Analysis and Research in Africa, a project funded by USAID and the Johns Hopkins Program on Training in Reproductive Health, has coordinated a study that will help guide the development of better policies on unsafe abortion. One phase involved the collection and analysis of all published and unpublished information from computer data bases dealing with the problem. The other phase involved interviews with health care workers, patients, and managers of health care facilities in Zambia, Malawi, and Uganda. In each of the 3 countries primary data was collected from a tertiary care hospital in the capital city, a provincial hospital, and 2 rural district hospitals. The results of the primary data component showed that services for the prevention of unwanted pregnancy and treatment of complications of abortion in this region are inadequate. Unsafe abortion was also a major public health problem in the region, costing national governments a lot of resources. Findings revealed that unsafe abortion is an enormous public health problem with staggering consequences for women and the health care system, which spend an inordinate amount of money, time, and other resources to treat the consequences of unsafe abortion. Complications leading to acute and chronic injuries and sometimes death, as a result of unsafe abortion, affect women at the prime of their lives. Postabortion family planning services, health care facilities, and counseling are lacking. The Recommendations and Policy Implications of the study will be discussed by the 22nd Conference of Health Ministers with a view to developing specific actions to avert the problem.

    Pressures for interruption of pregnancy by therapeutic abortion constantly increase, both for liberalization of laws and for interpreting existing law more broadly. There are wide variations and inconsistencies in psychiatric attitudes and practices about therapeutic abortion. Follow-up patient data are scant, but necessary. Results of questionnaires indicate that such data can be obtained, and convey the impression that patients seem to manage after pregnancy, regardless of outcome, much as they had before pregnancy. This study indicates that the incidence of suicide in pregnant women is approximately one-sixth that of the rate for non-pregnant women in comparable age groups, implying that perhaps pregnancy has a psychically protective role.

    In this commentary, the impact of the introduction of manual vacuum aspiration (MVA) for incomplete abortion patients and for early uterine evacuation is discussed for the University Teaching Hospital in Lusaka, Zambia. This 3-year training and service delivery program was begun in 1988 after it was clear that 15% of maternal deaths were due to illegally induced abortion. The prior procedure of dilation and curettage (D and C) required use of the main operating room and general anesthesia, which resulted in severe congestion and treatment delays. As a result of the new MVA procedure, congestion has decreased substantially, treatment is safer and more timely, and the staff's ability to provide abortions has increased. Family planning counseling is provided to postabortion patients in a more thorough fashion, and the savings in time has improved the quality of patient-staff interactions. Specifically, the patient flow has improved from a 12-hour wait to a 4-6 hour wait and rarely requires overnight hospitalization. The demand for the main operating room had decreased which frees space, time, and commodities for other gynecological treatment. The shorter procedure and release time means a minimal loss of earnings and productivity, and allows for greater privacy in explaining absences to families, schools, or employers. The improved quality of are is reflected in the figures for number treated, i.e., in 1989, 74% were treated with MVA for incomplete abortion 12 weeks and pregnancy termination 8 weeks compared with 26% treated with D and C. In 1990, the figures were 86% with MVA and 14% with D and C. The likelihood of complications from hemorrhage and sepsis have also been reduced. The MVA procedure is also less traumatic for the patient. The increased access to safe legal abortion services is reflected in the ratio of induced to incomplete abortions between 1988-1990 (1:25 to 1:5). Family planning counseling is provided by a full-time counselor who counsels preabortion

    1998-11-01

    Despite the efforts of pro-choice activists in the US to point out the critical differences between so-called "partial-birth abortions" and late-term abortions, the public remains confused about the issue. Proposed federal legislation banning "partial-birth abortions" excludes any language defining late-term abortions (time period or fetal viability). Thus, such a ban would apply to any abortion at any stage of pregnancy. Only the states of Kansas and Utah have passed legislation that limit the ban to late-term abortions. The term "partial-birth abortion" also has no independent meaning: it is not a medical term nor does it refer to a medical procedure. The correct term, "intact dilation and extraction," is never mentioned in most proposed legislation, much of which is written in broad enough language to outlaw all abortions. Most states that passed bans on "partial-birth abortions," in fact, had previously banned late-term abortions. In Georgia, a court order revised a "partial-birth abortion" law by limiting it to post-viability dilation and extraction and insisting on exceptions to protect the pregnant women's life and health. The courts have severely limited or enjoined "partial-birth abortion" legislation in 19 of the 20 states where challenges were mounted. Because an educated public overwhelmingly rejects the bans, reproductive rights activists are attempting to educate the public despite the inability or unwillingness of the media to make the crucial distinction.

    Abortion is an issue of great public concern and debate. The majority of US citizens support a woman's right to choose, but it has not always been that way. Abortion was made legal in 1973 but women have been abortions for hundreds of years before that. The history of abortion is therefore a history of women breaking the law and subjecting themselves to great physical and social risk. Abortion law in the US has been changed mostly by the Supreme Court. After Roe v Wade (1973) there were many other cases brought before the Court involving federal and state funding of abortion, father's rights, parental consent for minors, and many other finer points of law and policy regarding abortion. Abortion is commonly practiced in many developing countries including the ones where it is illegal. The data collected from these countries gives researchers here a great deal of information on the clinical and sociological aspects of abortion. Medical technology has broadened the scope of abortion by introducing medication to induce abortion such as RU486. Abortion is no longer an exclusively surgical procedure. Since it can performed now with a pill it will be almost impossible to regulate it as strictly as before.

    OBJECTIVE To analyze temporal trends and distribution patterns of unsafe abortion in Brazil. METHODS Ecological study based on records of hospital admissions of women due to abortion in Brazil between 1996 and 2012, obtained from the Hospital Information System of the Ministry of Health. We estimated the number of unsafe abortions stratified by place of residence, using indirect estimate techniques. The following indicators were calculated: ratio of unsafe abortions/100 live births and rate of unsafe abortion/1,000 women of childbearing age. We analyzed temporal trends through polynomial regression and spatial distribution using municipalities as the unit of analysis. RESULTS In the study period, a total of 4,007,327 hospital admissions due to abortions were recorded in Brazil. We estimated a total of 16,905,911 unsafe abortions in the country, with an annual mean of 994,465 abortions (mean unsafe abortion rate: 17.0 abortions/1,000 women of childbearing age; ratio of unsafe abortions: 33.2/100 live births). Unsafe abortion presented a declining trend at national level (R2: 94.0%, p < 0.001), with unequal patterns between regions. There was a significant reduction of unsafe abortion in the Northeast (R2: 93.0%, p < 0.001), Southeast (R2: 92.0%, p < 0.001) and Central-West regions (R2: 64.0%, p < 0.001), whereas the North (R2: 39.0%, p = 0.030) presented an increase, and the South (R2: 22.0%, p = 0.340) remained stable. Spatial analysis identified the presence of clusters of municipalities with high values for unsafe abortion, located mainly in states of the North, Northeast and Southeast Regions. CONCLUSIONS Unsafe abortion remains a public health problem in Brazil, with marked regional differences, mainly concentrated in the socioeconomically disadvantaged regions of the country. Qualification of attention to women’s health, especially to reproductive aspects and attention to pre- and post-abortion processes, are necessary and urgent strategies to be implemented

    For the last 30 years, the United States's human space program has been focused on low Earth orbit exploration and operations with the Space Shuttle and International Space Station programs. After nearly 50 years, the U.S. is again working to return humans beyond Earth orbit. To do so, NASA is developing a new launch vehicle and spacecraft to provide this capability. The launch vehicle is referred to as the Space Launch System (SLS) and the spacecraft is called Orion. The new launch system is being developed with an abort system that will enable the crew to escape launch failures that would otherwise be catastrophic as well as probabilistic design requirements set for probability of loss of crew (LOC) and loss of mission (LOM). In order to optimize the risk associated with designing this new launch system, as well as verifying the associated requirements, NASA has developed a comprehensive Probabilistic Risk Assessment (PRA) of the integrated ascent phase of the mission that includes the launch vehicle, spacecraft and ground launch facilities. Given the dynamic nature of rocket launches and the potential for things to go wrong, developing a PRA to assess the risk can be a very challenging effort. Prior to launch and after the crew has boarded the spacecraft, the risk exposure time can be on the order of three hours. During this time, events may initiate from either of the spacecraft, the launch vehicle, or the ground systems, thus requiring an emergency egress from the spacecraft to a safe ground location or a pad abort via the spacecraft's launch abort system. Following launch, again either the spacecraft or the launch vehicle can initiate the need for the crew to abort the mission and return to the home. Obviously, there are thousands of scenarios whose outcome depends on when the abort is initiated during ascent as to how the abort is performed. This includes modeling the risk associated with explosions and benign system failures that require aborting a

    The National Aeronautics and Space Administration created the Constellation program to develop the next generation of manned space vehicles and launch vehicles. The Orion abort system is initiated in the event of an unsafe condition during launch. The system has a controller gains schedule that can be tuned to reduce the attitude errors between the simulated Orion abort trajectories and the guidance trajectory. A program was created that uses the method of steepest descent to tune the pitch gains schedule by an automated procedure. The gains schedule optimization was applied to three potential abort scenarios; each scenario tested using the optimized gains schedule resulted in reduced attitude errors when compared to the Orion production gains schedule.

    How to manage to abortion request by a hypothetical 30-year old married woman who states the she fears a deformed child because of taking an antibiotic combination, cotrimoxazole, containing trimethoprim is discussed by 3 physicians. The 1st doctor would confirm pregnancy with an exam and a laboratory test, schedule another consultation for counseling, and schedule a pelvic ultrasound if she decides to carry the pregnancy. If she wants an abortion, the physician would counsel her at length about her marriage and the emotional consequences of abortion. The 2nd physician would advise her that fetal abnormality from trimethoprim has not been reported in women. Since this doctor is personally opposed to abortion, she would refer the patient to another doctor to make the arrangements, and counsel her again afterward. The 3rd physician added the advice that 1-2% of all U.K. births are abnormal in some way. He would take steps to establish the precise gestational date, recommend an ultrasound scan at 18 weeks to cover himself legally and suggest that the patient's husband join in the counseling session to help bring out feelings about the marriage and the pregnancy.

In particular, they argue that infanticide should be permitted even for reasons that do not primarily serve the interests (or would-be best interests) of the newborn. They claim that abortion is permissible for reasons that do not primarily serve the interests (or would-be interests) of the fetus because fetuses lack a right to life. They argue that newborns also lack a right to life, and they conclude that therefore, the same reasons that justify abortion can justify infanticide. This conclusion does not follow. The lack of a right to life is not decisive. Furthermore, the justificatory power of a given reason is a function of moral context. Generalisations about reasons across dissimilar moral contexts are invalid. However, a similar conclusion does follow-that fetus-killing and newborn-killing are morally identical in identical moral contexts-but this conclusion is trivial, since fetuses and newborns are never in identical moral contexts.

  15. Mifepristone and first trimester abortion.

    Murray, S; Muse, K

    The development of safe, effective, nonsurgical methods of pregnancy termination has the potential to avert significant maternal mortality and morbidity, especially in developing countries. RU-486 blocks the action of progesterone and cortisol, leading to structural changes in the endothelium of decidual capillaries, decidual necrosis, and subsequent detachment of the products of conception. When RU-486 is administered in conjunction with a low dose of a prostaglandin such as misoprostol, the abortion rate is comparable to that for vacuum aspiration (e.g., 94-96%). This regimen is contraindicated, however, in women aged 35 years and older, smokers, and those with medical problems such as diabetes, hypertension, clotting disorders, or anemia. In countries with strict abortion laws, RU-486 has been used to induce menstrual bleeding in women whose periods are delayed up to 10 days. An obstacle to more widespread acceptance of RU-486 has been its medicalization through national guidelines that stipulate waiting periods or require multiple visits to an approved abortion clinic. Women are likely to prefer RU-486 over surgical abortion because it allows the patient more control over her pregnancy termination and is less invasive. As political controversy continues to delay RU-486's introduction to the US and most developing countries, there are concerns that the drug will become a black market commodity used for self-induction.

  16. RU-486: the "abortion pill".

    PubMed

    Herranz, G

    1991-05-23

    A report sent by the Vatican to bishops' conferences throughout the world calls RU-486, the so-called abortion pill currently available in France, "a new, serious threat to human life." The report was developed at the Vatican's request by Gonzalo Herranz, a Spanish bioethicist. A cover letter to bishops' conferences from Cardinal Alfonso Lopez Trujillo, president of the Pontifical Council for the Family, suggested that the report be used "to resist the introduction of the abortion pill RU-486 into your country." Related to TU-486 and to new terminology some use to characterize its non-surgical approach to abortion is an intention "to amoralize and thereby place the transmission of human life into an ethically neutral terrain and reduce it to pure biology," says the report. The report discusses possible future uses of RU-486 as a contraceptive, stating: "Women would no longer have to worry themselves about whether they have conceived or not. Each month they would proceed to clean out their uterus chemically." The report refers to RU-486 as "a technical step forward in an area that did not need it." It says, "The abortion pill favors a woman's privacy and secret, but it condemns her to solitude." The English text from the Vatican follows. PMID:16145821

  17. Abort Trigger False Positive and False Negative Analysis Methodology for Threshold-Based Abort Detection

    This paper describes a quantitative methodology for bounding the false positive (FP) and false negative (FN) probabilities associated with a human-rated launch vehicle abort trigger (AT) that includes sensor data qualification (SDQ). In this context, an AT is a hardware and software mechanism designed to detect the existence of a specific abort condition. Also, SDQ is an algorithmic approach used to identify sensor data suspected of being corrupt so that suspect data does not adversely affect an AT's detection capability. The FP and FN methodologies presented here were developed to support estimation of the probabilities of loss of crew and loss of mission for the Space Launch System (SLS) which is being developed by the National Aeronautics and Space Administration (NASA). The paper provides a brief overview of system health management as being an extension of control theory; and describes how ATs and the calculation of FP and FN probabilities relate to this theory. The discussion leads to a detailed presentation of the FP and FN methodology and an example showing how the FP and FN calculations are performed. This detailed presentation includes a methodology for calculating the change in FP and FN probabilities that result from including SDQ in the AT architecture. To avoid proprietary and sensitive data issues, the example incorporates a mixture of open literature and fictitious reliability data. Results presented in the paper demonstrate the effectiveness of the approach in providing quantitative estimates that bound the probability of a FP or FN abort determination.

    Unintended pregnancy is common in Uganda, leading to high levels of unplanned births, unsafe abortions, and maternal injury and death. Because most pregnancies that end in abortion are unwanted, nearly all ill health and mortality resulting from unsafe abortion is preventable. This report summarizes evidence on the context and consequences of unintended pregnancy and unsafe abortion in Uganda, points out gaps in knowledge, and highlights steps that can be taken to reduce levels of unintended pregnancy and unsafe abortion, and, in turn, the high level of maternal mortality.

    This news brief presents the US President's wife's statement on the association between use of family planning and a decline in abortions worldwide. Hillary Rodham Clinton attended the Sixth Conference of Wives of Heads of State and Government of the Americas held in La Paz, Bolivia. The conference was suitably located in Bolivia, a country with the highest rates of maternal mortality in South America. Bolivia has responded by launching a national family planning campaign coordinated between government, nongovernmental, and medical organizations. Half of Bolivian women experience pregnancy and childbirth without the support of trained medical staff. Mortality from abortion complications account for about half of all maternal deaths in Bolivia. Voluntary family planning workers teach women about the benefits of child spacing, breast feeding, nutrition, prenatal and postpartum care, and safe deliveries. Bolivia has succeeded in increasing its contraceptive use rates and decreasing the number of safe and unsafe abortions. Bolivia's program effort was supported by USAID. USAID provided technical assistance and funds for the establishment of a network of primary health care clinics. Mrs. Clinton visited one such clinic in a poor neighborhood in La Paz, which in its first six months of operation provided 2200 consultations, delivered 200 babies, registered 700 new family planning users, and immunized 2500 children. Clinics such as this one will be affected by the US Congress's harsh cuts in aid, which reduce funding by 35% and delay program funding by 9 months. These US government cuts in foreign aid are expected to result in an additional 1.6 million abortions, over 8000 maternal deaths, and 134,000 infant deaths in developing countries. An investment in population assistance represents a sensible, cost-effective, and long-term strategy for improving women's health, strengthening families, and reducing abortion.

    The BSNS extraction system takes use one of the four dispersion-free straight sections. Five vertical kickers and one Lambertson septum magnet are used for the one-turn extraction. The rise time of less 250 ns and the total kicking angle of 20 mrad are required for the kickers that are grouped into two tanks. The design for the kicker magnets and the PFN is also given. To reduce the low beam loss in the extraction channels due to large halo emittance, large apertures are used for both the kickers and septum. Stray magnetic field inside and at the two ends of the circulating path of the Lambertson magnet and its effect to the beam has been studied.

    The contention that abortion harms women constitutes a new strategy employed by the pro-life movement to supplement arguments about fetal rights. David C. Reardon is a prominent promoter of this strategy. Post-abortion syndrome purports to establish that abortion psychologically harms women and, indeed, can harm persons associated with women who have abortions. Thus, harms that abortion is alleged to produce are multiplied. Claims of repression are employed to complicate efforts to disprove the existence of psychological harm and causal antecedents of trauma are only selectively investigated. We argue that there is no such thing as post-abortion syndrome and that the psychological harms Reardon and others claim abortion inflicts on women can usually be ascribed to different causes. We question the evidence accumulated by Reardon and his analysis of data accumulated by others. Most importantly, we question whether the conclusions Reardon has drawn follow from the evidence he cites. PMID:19594725

    An historical review of the use of induced abortion is presented, beginning with early eras. The Chinese were the 1st to record the practice of induced abortion, with this operation being administered to royal concubines recorded at 500-515 B.C. Induced abortion was not used in ancient Greece, either for criminal or ethical reason. However, the ancient Greeks did utilize compulsory abortion for serious economic indications, as a means of controlling natural growth. Greek medical, gyneoclogigcal instruments for adminsitering abortions were described by Hippocrates. The Greek moral attitudes on abortion were largely adopted by the Romans, which were later altered by the appearance of Christianity and new ethical ideas. These ideas dominated European attitudes, along with the Church of Rome, limiting induced abortion to cases where the life of the mother was threatened. This attitude has existed until the present century, when these moral ideas are being challanged seriously for the 1st time in modern history. PMID:4610534

    Students (N = 118) were classified as pro-choice, anti-abortion, or mixed on the basis of their responses to ten fictitious case histories of females who requested abortion. The distribution of participants on the abortion issue was quite similar to the results of a 1979 national survey. As expected, these groups differed on attitudes toward abortion as murder, the legalization of abortion, and the morality of premarital sex. The groups differed significantly in levels of sex guilt, but did not exhibit significant differences in levels of sexual knowledge. The results were discussed within the context of the public controversy over abortion. It was suggested that the affective messages accompanying the sexual socialization of children and adolescents may be more predictive of orientations toward abortion than the weight of intellectual arguments regarding the rights of the fetus, the point at which a fetus becomes viable, or a woman's right to have control over her own body.

    The Orion Crew Exploration Vehicle is the first crewed capsule design to be developed by NASA since Project Apollo. Unlike Apollo, however, the CEV is being designed for service in both Lunar and International Space Station missions. Ascent aborts pose some issues that were not present for Apollo, due to its launch azimuth, nor Space Shuttle, due to its cross range capability. The requirement that a North Atlantic splashdown following an abort be avoidable, in conjunction with the requirement for overlapping abort modes to maximize crew survivability, drives the thrust level of the service module main engine. This paper summarizes 3DOF analysis conducted by NASA to aid in the determination of the appropriate propulsion system for the service module, and the appropriate propellant loading for ISS missions such that crew survivability is maximized.

    Botswana's national healthcare system has experienced substantial investment as a result of a growing economy and stable government, and improvements in quality and access are notable. Despite these advances, women's reproductive health continues to suffer as a result of unsafe abortion. The personal, financial, and health costs of women seeking dangerous illegal terminations, or crossing national borders to procure a legal abortion, are evident. Twenty-one in-depth, qualitative interviews with Batswana were conducted to gain some insight into the factors which make terminating an unwanted pregnancy difficult in Botswana. This small study demonstrates that there are important socio-cultural constraints, in addition to the legal barriers, that make abortion problematic. These constraints are entrenched in the wider issue of women's rights and status in society. PMID:24558781

    Every year around 500,000 women are estimated to die from pregnancy-related causes, the majority in the developing world and many as a consequence of unsafe abortion. Around 25 per cent of maternal deaths in Asia and 30-50 per cent of maternal deaths in Africa and Latin America occur as a result of induced abortion. Data on abortion related maternal morbidity is less reliable than mortality but suggests that for every maternal death 10-15 women suffer significant pregnancy-related morbidity, i.e. infertility, genito-urinary problems and/or chronic pain. Induced abortion occurs in practically every society in the world but only 40 per cent of the women in the world live in countries where abortion is legally free. A permissive legislation is an important prerequisite for medically safe and early abortion. Oppositely, with a restrictive law, abortion is difficult to obtain, costly and possibly unsafe, in particular to the least affluent women in the society. Induced abortion in a developed country with legal and easy access to services is a safe procedure with hardly any mortality and very low morbidity. The best strategy to reduce the number of unsafe abortions is prevention of unwanted pregnancy. The consequences of unsafe abortion on women's health need to be acknowledged by everybody in the society in order to improve abortion care. It is necessary to adjust legal and other barriers to medically safe abortion in order to follow the declaration at the UN conference on population in Cairo, 1994, which stated that abortion, wherever legal, should be safe. It is also necessary to introduce preventive measures where abortions are performed, i.e. good and easily accessible family planning services.

    Studies suggest that headache accounts for approximately 1% of pediatric emergency department (ED) visits. ED physicians must distinguish between primary headaches, such as a tension or migraine, and secondary headaches caused by systemic disease including neoplasm, infection, or intracranial hemorrhage. A recent study found that 40% of children presenting to the ED with headache were diagnosed with a primary headache, and 75% of these were migraine. Once the diagnosis of migraine has been made, the ED physician is faced with the challenge of determining appropriate abortive treatment. This review summarizes the most recent literature on pediatric migraine with an emphasis on diagnosis and abortive treatment in the ED.

    Because the primary responsibility for the care and raising of children still falls on women, they should be able to decide freely whether or not to have children. Although many women who do not initially desire their pregnancies turn out to be adequate mothers, studies have shown that unwanted children suffer disproportionately from a variety of emotional and behavioral disorders. Studies have also found that large numbers of women seeking abortions failed to use any contraception while others used less effective methods, sometimes because of lack of knowledge. Even the most reliable contraceptive methods are liable to occasional failures. According to some authors, undesired pregnancy many reflect a struggle of adolescents with authoritarian parents, the search of a lonely person for something to love or possess, a proof of femininity, an expression of conflict with the partner or an attempt to force a marriage, or ambivalence among middle-aged women at the prospect of becoming more independent when their children enter school. Women may obtain abortions at accredited hospitals in the Province of Quebec upon decision of a committee of 3 physicians that continuation of the pregnancy would result in danger to the life or health of the patient. In 1970 some 100-150,000 illegal abortions occurred, resulting in hospitalization of 20,000 women for complications. In 1972, 4 French-speaking hospitals performed 136 of the 2919 therapeutic abortions sought in the Province of Quebec. In recent years the number has increased. Reasons for obtaining an abortion are usually social or economic: poor relationship with the father, sufficient number of children already born, age of the preceding infant, economic difficulties, mother's age, or effect of pregnancy on work. Many adolescents refuse to tell their parents of their pregnancy for fear of their reaction, but others enjoy considerable parental support.

    Background Unsafe abortion contributes to a significant portion of maternal mortality in India. Access to safe abortion care is known to reduce maternal mortality. Availability and distribution of abortion care facilities can influence women's access to these services, especially in rural areas. Objectives To assess the availability and distribution of abortion care at facilities providing childbirth care in three districts of Madhya Pradesh (MP) province of India. Design Three socio demographically heterogeneous districts of MP were selected for this study. Facilities conducting at least 10 deliveries a month were surveyed to assess availability and provision of abortion services using UN signal functions for emergency obstetric care. Geographical Information System was used for visualisation of the distribution of facilities. Results The three districts had 99 facilities that conducted >10 deliveries a month: 74 in public and 25 in private sector. Overall, 48% of facilities reported an ability to provide safe surgical abortion service. Of public centres, 32% reported the ability compared to 100% among private centres while 18% of public centres and 77% of private centres had performed an abortion in the last 3 months. The availability of abortion services was higher at higher facility levels with better equipped and skilled personnel availability, in urban areas and in private sector facilities. Conclusions Findings showed that availability of safe abortion care is limited especially in rural areas. More emphasis on providing safe abortion services, particularly at primary care level, is important to more significantly dent maternal mortality in India. PMID:25797220

    Mars trajectory design options were examined that would accommodate a premature termination of a nominal manned opposition class mission for opportunities between 2010 and 2025. A successful abort must provide a safe return to Earth in the shortest possible time consistent with mission constraints. In this study, aborts that provided a minimum increase in the initial vehicle mass in low Earth orbit (IMLEO) were identified by locating direct transfer nominal missions and nominal missions including an outbound or inbound Venus swing-by that minimized IMLEO. The ease with which these missions could be aborted while meeting propulsion and time constraints was investigated by examining free return (unpowered) and powered aborts. Further reductions in trip time were made to some aborts by the addition or removal of an inbound Venus swing-by. The results show that, although few free return aborts met the specified constraints, 85% of each nominal mission could be aborted as a powered abort without an increase in propellant. Also, in many cases, the addition or removal of a Venus swing-by increased the number of abort opportunities or decreased the total trip time during an abort.

    2016-06-01

    As in other post-Soviet settings, induced abortion has been widely used in Armenia. However, recent national survey data point to a substantial drop in abortion rates with no commensurate increase in modern contraceptive prevalence and no change in fertility levels. We use data from in-depth interviews with women of reproductive age and health providers in rural Armenia to explore possible underreporting of both contraceptive use and abortion. While we find no evidence that women understate their use of modern contraception, the analysis suggests that induced abortion might indeed be underreported. The potential for underreporting is particularly high for sex-selective abortions, for which there is growing public backlash, and medical abortion, a practice that is typically self-administered outside any professional supervision. Possible underreporting of induced abortion calls for refinement of both abortion registration and relevant survey instruments. Better measurement of abortion dynamics is necessary for successful promotion of effective modern contraceptive methods and reduction of unsafe abortion practices.

    For the last 30 years, the United States' human space program has been focused on low Earth orbit exploration and operations with the Space Shuttle and International Space Station programs. After over 40 years, the U.S. is again working to return humans beyond Earth orbit. To do so, NASA is developing a new launch vehicle and spacecraft to provide this capability. The launch vehicle is referred to as the Space Launch System (SLS) and the spacecraft is called Orion. The new launch system is being developed with an abort system that will enable the crew to escape launch failures that would otherwise be catastrophic as well as probabilistic design requirements set for probability of loss of crew (LOC) and loss of mission (LOM). In order to optimize the risk associated with designing this new launch system, as well as verifying the associated requirements, NASA has developed a comprehensive Probabilistic Risk Assessment (PRA) of the integrated ascent phase of the mission that includes the launch vehicle, spacecraft and ground launch facilities. Given the dynamic nature of rocket launches and the potential for things to go wrong, developing a PRA to assess the risk can be a very challenging effort. Prior to launch and after the crew has boarded the spacecraft, the risk exposure time can be on the order of three hours. During this time, events may initiate from either the spacecraft, the launch vehicle, or the ground systems, thus requiring an emergency egress from the spacecraft to a safe ground location or a pad abort via the spacecraft's launch abort system. Following launch, again either the spacecraft or the launch vehicle can initiate the need for the crew to abort the mission and return home. Obviously, there are thousands of scenarios whose outcome depends on when the abort is initiated during ascent and how the abort is performed. This includes modeling the risk associated with explosions and benign system failures that require aborting a spacecraft under very

    CONTEXT Because of Nigeria’s low contraceptive prevalence, a substantial number of women have unintended pregnancies, many of which are resolved through clandestine abortion, despite the country’s restrictive abortion law. Up-to-date estimates of abortion incidence are needed. METHODS A widely used indirect methodology was used to estimate the incidence of abortion and unintended pregnancy in Nigeria in 2012. Data on provision of abortion and postabortion care were collected from a nationally representative sample of 772 health facilities, and estimates of the likelihood that women who have unsafe abortions experience complications and obtain treatment were collected from 194 health care professionals with a broad understanding of the abortion context in Nigeria. RESULTS An estimated 1.25 million induced abortions occurred in Nigeria in 2012, equivalent to a rate of 33 abortions per 1,000 women aged 15–49. The estimated unintended pregnancy rate was 59 per 1,000 women aged 15–49. Fifty-six percent of unintended pregnancies were resolved by abortion. About 212,000 women were treated for complications of unsafe abortion, representing a treatment rate of 5.6 per 1,000 women of reproductive age, and an additional 285,000 experienced serious health consequences but did not receive the treatment they needed. CONCLUSION Levels of unintended pregnancy and unsafe abortion continue to be high in Nigeria. Improvements in access to contraceptive services and in the provision of safe abortion and postabortion care services (as permitted by law) may help reduce maternal morbidity and mortality.

    In January 1994, the Health Service published its statistics about pregnancy prevention and abortion in 1991 and 1992. The number of legal abortions was 19,729 in 1991 and 18,833 in 1992, which was the lowest figure since the law was introduced about elective abortion in 1973. 2623 fewer abortions were carried out in 1992 than five years before. The general abortion rate decreased from 15.8 in 1990 to 14.9 in 1992 (it was the highest in 1975 with 23.7). The age-specific abortion rate fell mostly in the 18-29 age group, with fewer in the 15-19 and 30-34 age groups. The number of children who were born to women over 40 increased from 390 in 1982 to 864 in 1992, while the birth rate of women under 20 decreased to almost half. The abortion rate was the highest in large cities, it was about 2.5 times higher than in the county of Ringkobing, which had the lowest rate, especially in the age groups under 25 years. The combined abortion rate (per 1000 women of reproductive age) was 578 in 1982, 540 in 1990, and 505 in 1992. 97.5% of abortions were performed within 12 weeks of pregnancy in accordance with the abortion law. 2% of abortions were carried out because of the woman's health or for social indications. 80% of abortions were performed in the 10th week of pregnancy mostly with vacuum aspiration. Complications decreased compared to previous years, and made up 2.6% of all abortions in 1992, mainly bleeding and, for 1/5 of them, inflammatory conditions. Half of the women who underwent an abortion in 1992 had given birth to at least one living child, 8% to more than three. Half of the 20% of women who could given birth but chose abortion had given birth in the previous two years and 27% within less than a year before abortion. The number of spontaneous abortions was 10,717 in 1991 and 10,605 in 1992, about 1000 fewer than in 1990. The number of male sterilizations fell from 2784 in 1991 to 1722 in 1992, and female sterilizations from 4777 to 4429. About 13 million condoms

    1983-01-01

    For many years, illegal abortion has been denounced in Spain. The estimate of 300,000 abortions annually is widely quoted but poorly founded in fact. Weekend "charters" to London and Amsterdam for women seeking abortions have been commented upon, denounced, and caricatured. The evidence indicates that abortions occur in Spain despite their illegality, just as they occur in every other country and have always occurred. Poor women abort in a poor way, with traditional healers, while rich women abort in a rich way, with physicians. "Charters" are the solution of the middle class. Proposed legislation in Spain would permit abortion on 3 grounds: rape, fetal malformation, and risk to the woman's life if the pregnancy continued. Excesses have been committed both by those opposing abortion and by those struggling for liberalization of laws. Defenders of abortion, such as radical feminists, appear to forget that abortion is a medical procedure with possible dangerous psychophysical consequences, and that preventive measures such as sex education and diffusion of contraception or social measures such as assistance for unwed mothers and their children would be preferrable to abortion. There is the question of whether medical personnel should be excused from assisting in abortions on grounds of conscience and whether those who do assist in abortions automatically become "progressive" by doing so. The staunchest defenders of fetal life are not moved to contribute anything beyond words to improvement of the plight of the many millions of already born who live in miserable conditions of hunger and want. Abortion is a violent act against the fetus and the pregnant woman. Its criminalization is a violent act against the woman and a social intrusion into matters better left to personal ethics. The government which proposes abortion on a few grounds fails to initiate a program to promote life through social protection of single mothers and their children or of families in general

    Ceramic beam tubes are utilized in numerous kicker magnets in different accelerator rings at Fermi National Accelerator Laboratory. Kovar flanges are brazed onto each beam tube end, since kovar and high alumina ceramic have similar expansion curves. The tube, kovar flange, end piece, and braze foil (titanium/incusil) alloy brazing material are stacked in the furnace and then brazed in the furnace at 1000 C. The ceramic specified is 99.8% Alumina, Al{sub 2}O{sub 3}, a strong recrystallized high-alumina fabricated by slip casting. Recent experience at Fermilab with the fabrication and brazing of these tubes has brought to light numerous problems including tube breakage and cracking and also the difficulty of brazing the tube to produce a leak-tight joint. These problems may be due to the ceramic quality, voids in the ceramic, thinness of the wall, and micro-cracks in the ends which make it difficult to braze because it cannot fill tiny surface cracks which are caused by grain pullout during the cutting process. Solutions which are being investigated include lapping the ends of the tubes before brazing to eliminate the micro-cracks and also metallization of the tubes.

    I present in this paper preliminary design concepts for a fast kicker magnet and driver for the rapid transfer of the electron beam between radiator beam lines in LUX. This paper presents a feasibility study to find a roughly optimized subset of engineering parameters that would satisfy the initial design specifications of: Pulse width < 30 mu s, rise / fall time < 10 mu s, time jitter < 1ns, magnetic length < 0.5meter, gap height = 15mm, gap width = 25mm, peak field = 0.6Tesla, bend angle = 1.7 deg. for beam energy of 3.1 Gev, repetition rate = 10KHz. An H magnet core configuration was chosen. Through an iterative mathematical process employing Mathcad 11 [1] a realizable design was chosen. Peak current, Peak voltage across the coils, conductor losses due to proximity and skin effects, and basic circuit topology were investigated. Types and losses of core material were only briefly discussed. The final topology consists of two magnets in series running at 10KHz, .3Tesla, 630 amp peak current, 10 mu s pulse width, 693 Watts per coil section, driven by fast solid state switch with an energy recovery inductor.

    Human leukocyte antigen (HLA)-G is involved in immunoregulatory processes and particularly in pathogenesis of inflammatory disorders such as recurrent spontaneous abortions (RSA). The purpose of the current study was to examine whether two single nucleotide polymorphisms (SNPs) of HLA-G gene (rs1736936 and HLA-G*0105N) influence susceptibility to recurrent spontaneous abortion. Genomic DNA from 117 RSA patients and 117 normal fertile control individuals was isolated using the salted out method. The two single nucleotide polymorphisms in HLA-G gene were analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Differences between the two groups were analyzed by SPSS19 software using Chi-square test. The results revealed a significant increase in HLA-G*0105N allele in the proportion of whole group of RSA women compared with fertile controls (P value = 0.015), OR (95 % CI) = 2.054 (1.798-2.347), as well as an absence of homozygosity for HLA-G*0105N in the study population. No significant difference was observed between the RSA and the fertile groups in terms of alleles and genotypes frequency of rs1736936 (P value = 0.323), OR (95 CI %) = 1.056 (0.844-1.319). The presented data suggest that the investigated HLA-G*0105N allele is potentially associated with RSA through linkage disequilibrium with other genetic elements. Meanwhile, the rs1736936 SNP do not predispose to RSA in the study population.

    Although unsafe abortion continues to be a leading cause of maternal mortality in many countries in Asia, the right to safe abortion remains highly stigmatized across the region. The Asia Safe Abortion Partnership, a regional network advocating for safe abortion, produced an animated short film entitled From Unwanted Pregnancy to Safe Abortion to show in conferences, schools and meetings in order to share knowledge about the barriers to safe abortion in Asia and to facilitate conversations on the right to safe abortion. This paper describes the making of this film, its objectives, content, dissemination and how it has been used. Our experience highlights the advantages of using animated films in addressing highly politicized and sensitive issues like abortion. Animation helped to create powerful advocacy material that does not homogenize the experiences of women across a diverse region, and at the same time emphasize the need for joint activities that express solidarity.

    Over the last decades a debate on the psychological and psychiatric consequences of the right to abortion took place. Abortion is a word-wide phenomenon linked to different aspects of public health. Although negative consequences are assumed to occur after abortion, most of the women who decide to terminate their pregnancy show several signs of relief. For instance, a decrease of signs of anxiety and depression may occur during the first month after abortion. Actually, the critical moment is the pre-abortion period. In this phase, most of the psychiatric and psychologic manifestations take place. Moreover, recent studies reinforce the importance to address the consequences of abortion with a multidisciplinary approach integrating somatic and psychologic components.

    In Sri Lanka, women do not have access to legal abortion except under life-saving circumstances. Clandestine abortion services are, however, available and quite accessible. Although safe specialist services are available to women who can afford them, others access services under unsafe and exploitative conditions. At the time of this writing, a draft bill that will legalize abortion in instances of rape, incest, and fetal abnormalities awaits approval, amid opposition. In this article, I explore the current push for legal reform as a solution to unsafe abortion. Although a welcome effort, this amendment alone will be insufficient to address the public health consequences of unsafe abortion in Sri Lanka because most women seek abortions for other reasons. Much broader legal and policy reform will be required.

    The abolition of legal abortion in the US would seriously threaten the health, and even the lives, of women and children. Statistics on the relationship between abortion and health attained before and after abortion was legalized were used to project some of the probable consequences of reversing the US Supreme Court's 1973 Roe v. Wade decision. Abortion has been widely practiced throughout US history, but the actual number of procedures performed before some states legalized abortion is unknown. Few legal procedures were performed for medical reasons, yet many illegal abortions took place. In 1955, a panel of experts could only provide a "best estimate" of between 200,000 and 1,200,000 illegally induced abortions occurring annually in the US. The actual number was most likely closer to the higher figure. The complication rates for illegal abortions, most of which were performed by unskilled practitioners in unsafe settings, were much higher than the rates for legal abortion now. Complications were related to ineffective or unsafe methods, Sepsis, particularly with the bacterium "Clostridium prefringens," which causes gas gangrene, was a major problem that has virtually disappeared. Each year prior to the 1970s, more than 100 women in the US died of abortion complications. Due to the fact that vital statistics reflect an incomplete ascertainment of deaths, the actual number of deaths is probably larger, possibly by as much as 50%. In 1983 more than 1.3 million procedures were performed -- a figure close to the estimated number of illegal abortions performed before 1970. In comparison, 672,000 hysterectomies and 424,000 tonsillectomy operations were performed the same year. The number of abortion-related deaths in the US decreased between 1972 and 1980, from 90 to 16. Most of this decrease resulted from the availability and safety of legal abortion. Legal abortion carries an especially low risk of death, particularly when performed in the 1st trimester. For the 1972

    With the passing of the Fourth World Conference on Women in Beijing, China, women's issues in Asia have moved increasingly to the forefront. One such issue, abortion, continues to generate controversy as many women argue for protection and/or recognition of their reproductive rights. The objectives of this paper are threefold: (1) To examine the abortion debate in Thailand, identifying issues raised by Thai feminist scholars about the status of women; (2) To overview some of the more prominent feminist arguments regarding abortion (particularly those written by Canadian and American scholars) as a tool for defining women's reproductive rights; (3) To focus on a study of attitudes toward abortion among health care personnel and post-induced abortion patients in Bangkok, Thailand in order to discern the degree of support (if any) for feminist abortion arguments.

    During the 1969-1970 school year, 351 upperclassmen at a southeastern university were used in a study on the use of different communication methods to change attitudes toward abortion. Following the pretest questionnaire, the group was divided into 4 groups and treated in the following ways: 1) a panel from the group presented pros and cons of abortion; 2) the group broke into 5-member discussion groups to talk about attitudes toward abortion; 3) a movie on normal birth was presented to this group; and 4) the 4th group received no interim abortion-related communication. The movie had no effect on abortion attitudes. The discussions had a slight liberalizing effect on abortion attitudes. Less than 3% of the students in the survey changed their attitude.

    Self-in-relation theory and pilot data responses to an Abortion Decision Balance Sheet by 20 women attending an abortion-providing clinic challenge previous formulations of the abortion decision. Pilot data suggest that: women may make an abortion decision based primarily on pragmatics, a belief in their right to choose and knowledge of the safety and simplicity of the procedure. A discrepancy may exist for a significant minority of women between their abstract beliefs/knowledge and the personal meaning for them of the pregnancy, abortion and its safety. Important links may exist between maternal attachment and anxiety about the safety of the abortion procedure. Ramifications for counselling and future research are discussed. PMID:8528379

  14. Abortion: a guide to making ethical choices.

    PubMed

    Maguire, M R; Maguire, D C

    1983-09-01

    A mature attitude toward abortion rests on responsible decision-making and action taking, not on the belief in irreversible events. Abortion is therefore a choice which should be made if it is the most correct and responsible action in view of one's own circumstances. There are a number of doubts, concerns and moral--as opposed to medical--questions that women may be asking themselves as they face this serious choice. The guide addresses these issues to help women think through that choice. It is important to know, for instance, that the Pope has never formally proclaimed a doctrine of faith on the matter of abortion. The Catholic Church, when considered in its diversity, teaches that some abortions can be moral; the conscience of a person is the final arbiter of any abortion decision. Conscience is humans' progressively refined ability to think about situations and evaluate their moral goodness/badness. With respect to abortion, this means that a woman should make the choice that seems best to her. The fear that having an abortion will result in excommunication from the Church is dismissed here. A distinction must be made between committing the sin of abortion and having an abortion. The former obtains when people act against their own conscience. The attitude toward abortion as murder and the issue of the fetus' afterlife are responded to in terms of personhood, a complicated concept on which there is no legal, scientific or religious consensus. Instead, the answer is a function of the time period and its prevalent beliefs. Today, the viability of the fetus has become an important determinant of life. Having an abortion, giving birth, and use of contraceptives when no children are wanted, are responses to which a woman is entitled. Her choice is moral when based on responsible and conscious decisions and actions. The views of Protestantism and Judaism on abortion are clarified briefly.

    This article concerns the relationship between fertility and legal abortivity in the first 5-year period of the 80's. The legal abortivity pattern of married women, by age and prior fertility is studied in 4 typical regions. This typology is stated considering both levels of fertility of abortivity at 1980-81 (low fertility-low abortivity; low fertility-high abortivity; high fertility-high abortivity; high fertility-low abortivity). In each region the change in the age-conception order specifies abortivity rate is examined by a regression model. Same interesting results can be stressed. Young women seem to be the most involved in the changing fertility pattern during the years considered. They appear at 1984-85 with a number of children more strictly reduced than during 1980-81. Of them, those residing in the too low fertility regions, as well as those residing in the high fertility-high abortivity region seem to be exposed to a lower risk of a legal abortion. The same results cannot be found for young residents in the high fertility-low abortivity region. In other words, those above seem to be in progress as it concerns the prevention possibility of an unplanned conception, otherwise the same cannot be stated for these latter. Many more women had a legal abortion in the early 80's, while less younger women, in a similar status, seem to risk the same 5 years later. At least, spreading knowledge about family planning methods seems to be working as outlined in the spirit of the 194 law operating in public health services. (Author's modified).

    Biochemical research of biological systems is highly developed, and it has disclosed a spectrum of chemical reactions, genetic processes, and the pathological development of various diseases. The fundamental hypothesis of physical processes in biological systems, in particular of coherent electrically polar vibrations and electromagnetic activity, was formulated by H. Fröhlich he assumed connection of cancer process with degradation of coherent electromagnetic activity. But the questions of cellular structures capable of the coherent electrical polar oscillation, mechanisms of energy supply, and the specific role of the endogenous electromagnetic fields in transport, organisation, interactions, and information transfer remained open. The nature of physical disturbances caused by some diseases (including the recurrent abortion in humans and the cancer) was unknown. We have studied the reasons of recurrent abortions in humans by means of the cell mediated immunity (using immunologic active RNA prepared from blood of inbred laboratory mice strain C3H/H2K, infected with the lactate dehydrogenase elevating virus-LD V) and the cytogenetic examination from karyotype pictures. The recurrent abortion group contained women with dg. spontaneous abortion (n = 24) and the control group was composed of 30 healthy pregnant women. Our hypothesis was related to quality of endometrium in relation to nidation of the blastocyst. The energetic insufficiency (ATP) inhibits normal development of fetus and placenta. We hope that these ideas might have impact on further research, which could provide background for effective interdisciplinary cooperation of malignant and non-malignant diseases.

  18. Use of Heated Helium to Simulate Surface Pressure Fluctuations on the Launch Abort Vehicle During Abort Motor Firing

    The solid-rocket plumes from the Abort motor of the Multi-Purpose Crew Vehicle (MPCV, also know as Orion) were simulated using hot, high pressure, Helium gas to determine the surface pressure fluctuations on the vehicle in the event of an abort. About 80 different abort situations over a wide Mach number range, (0.3< or =M< or =1.2) and vehicle attitudes (+/-15deg) were simulated inside the NASA Ames Unitary Plan, 11-Foot Transonic Wind Tunnel. For each abort case, typically two different Helium plume and wind tunnel conditions were used to bracket different flow matching critera. This unique, yet cost-effective test used a custom-built hot Helium delivery system, and a 6% scale model of a part of the MPCV, known as the Launch Abort Vehicle. The test confirmed the very high level of pressure fluctuations on the surface of the vehicle expected during an abort. In general, the fluctuations were found to be dominated by the very near-field hydrodynamic fluctuations present in the plume shear-layer. The plumes were found to grow in size for aborts occurring at higher flight Mach number and altitude conditions. This led to an increase in the extent of impingement on the vehicle surfaces; however, unlike some initial expectations, the general trend was a decrease in the level of pressure fluctuations with increasing impingement. In general, the highest levels of fluctuations were found when the outer edges of the plume shear layers grazed the vehicle surface. At non-zero vehicle attitudes the surface pressure distributions were found to become very asymmetric. The data from these wind-tunnel simulations were compared against data collected from the recent Pad Abort 1 flight test. In spite of various differences between the transient flight situation and the steady-state wind tunnel simulations, the hot-Helium data were found to replicate the PA1 data fairly reasonably. The data gathered from this one-of-a-kind wind-tunnel test fills a gap in the manned-space programs

    2015-11-01

    Surgical abortion has been provided liberally in Australia since the early 1970s, mainly in privately owned specialist clinics. The introduction of medical abortion, however, was deliberately obstructed and consequently significantly delayed when compared to similar countries. Mifepristone was approved for commercial import only in 2012 and listed as a government subsidised medicine in 2013. Despite optimism from those who seek to improve women's access to abortion, the increased availability of medical abortion has not yet addressed the disadvantage experienced by poor and non-metropolitan women. After telling the story of medical abortion in Australia, this paper considers the context through which it has become available since 2013. It argues that the integration of medical abortion into primary health care, which would locate abortion provision in new settings and expand women's access, has been constrained by the stigma attached to abortion, overly cautious institutionalised frameworks, and the lack of public health responsibility for abortion services. The paper draws on documentary sources and oral history interviews conducted in 2013 and 2015. PMID:26719008

    The frequency of pregnancy and delivery complications in women whose previous pregnancy had been terminated by a legally induced abortion is evaluated in a prospective and a retrospective study. Bleeding before 28 weeks of gestation and retention of placenta or placental tissue occurred more frequently after legal abortion that in a control group matched for age, parity, and socio-economic status. Other pregnancy and delivery complications did not occur more frequently after legal abortion. It is of particular interest that the study could not demonstrate an increased frequency of low birth weight among women whose previous pregnancy had been terminated by legal abortion.

    This study analyzes the involvement of men in abortion in Vietnam, where induced abortion is legal and abortion rates are among the highest in the world. Twenty men were interviewed in 1996 about the role they played in their wives' abortions and about their feelings and ethical views concerning the procedure. The results showed that both husbands and wives considered the husband to be the main decisionmaker regarding family size, which included the decision to have an abortion, but that, in fact, some women had undergone an abortion without consulting their husbands in advance. Parents and in-laws were usually not consulted; the couples thought they might object to the decision on moral grounds. Respondents' ethical perspectives on abortion are discussed. When faced with an unwanted pregnancy, the husbands adopted an ethics of care and responsibility toward family and children, although some felt that abortion was immoral. The study highlights the importance of understanding husbands' perspectives on their responsibilities and rights in reproductive decisionmaking and their ethical and other concerns related to abortion.

    In January 1988 the Supreme Court of Canada struck down the country's archaic abortion law on the ground that it imposed arbitrary delays and unfair disparities in access to abortion across the country. Since then, the conservative government of Canada has made a few attempts to introduce a new abortion policy, but it did not get passed in the parliament because the revised bills failed to protect women's right to 'life, liberty, and security of the person' within the meaning of the Canadian Charter. Canada has been without an abortion law for over four years and there has been a wide range of provincial policies and confusion in the country. Despite the legal vacuum, Canadian women are not frenziedly having abortions. However, the militancy of the anti-abortion groups has steadily intensified with continued assault on a woman's right to make reproductive choices. Since no law, short of banning abortions altogether, is going to satisfy abortion opponents, the abortion battle will rage on in Canada. PMID:8065237

    1987-01-01

    In the 1984 election, Ronald Reagan, the Republican presidential incumbent and an opponent of legal abortion, defeated Walter Mondale, a prochoice Democrat, by a wide margin. Despite Reagan's sweep of 49 states, however, conservatives lost a little ground in the Senate, where four of the seven new senators elected take a prochoice position on abortion. On the other hand, antiabortion forces registered some gains in the House of Representatives. The voting groups were more divided over the abortion issue in 1984 than they had been in 1980: In 1980, Reagan voters and Carter voters did not differ significantly in their attitudes toward abortion, but in 1984, Reagan voters were significantly more likely to be opposed to abortion than were Mondale voters. Nevertheless, only a small minority of voters considered abortion to be a major national issue, and the two voter groups were far more divided on several other issues than they were on abortion. There was no antiabortion consensus among the electorate as a whole, or among Reagan voters in particular. The level of approval for legalized abortion has, in fact, remained quite stable since 1973, and a popular base in favor of banning abortion seems to be lacking. PMID:3595819

  4. Two steps back: Poland's new abortion law.

    PubMed

    Nowicka, W

    1993-06-01

    After the fall of Communism in Poland, the Catholic church exerted pressure to increase its influence in public life. One way in which this pressure has manifested itself has been in the passing of a restrictive abortion bill which was signed into law on February 15, 1993. Abortion had been legalized in Poland in 1956 and was used as a means of birth control because of a lack of availability and use of contraceptives. The number of abortions performed was variously reported as 60,000 - 300,000/year. In 1990, the Ministry of Health imposed restrictions on abortions at publicly funded hospitals, and 3 deaths were reported from self-induced abortions. In 1 year (1989-90), the number of induced abortions at 1 hospital dropped from 71 to 19, while the number of self-induced abortions increased from 48 to 85. Further restrictions were introduced in May 1992 as part of the "Ethical Code for Physicians," which allows abortions only in cases where the mother's life or health is in danger or in cases or rape. This code brought abortions to a halt at publicly funded hospitals and doubled or even tripled the cost of private abortions. Women have been refused abortions in tragic and life=threatening situations since the code was adopted. When an outright anti family planning bill was drafted in November 1992, the Polish citizenry collected 1,300,000 signatures to force a referendum. The referendum was not held, but the bill was defeated. The amended bill which passed allows abortions in publicly funded hospitals only when the mother's life or health is in danger and in cases of rape, incest, or incurable deformity of the fetus. The implications of this law remain unclear, since its language is strange and vague. The reproductive rights of Polish women face a further threat because the Catholic church is working to limit the availability of contraceptive methods which they deem to be "early abortives." On the other side of the issue, the Federation for Women and Planned

    This article reports the results of a survey, by mailed questionnaire, of the attitudes among a sample of the Danish population towards abortion for social and genetic reasons. Of 1080 questionnaires sent to a random sample of persons between 18 and 45 years, 731 (68%) were completed and returned. A great majority of the respondents were liberal towards early abortion both for social reasons and in case of minor disease. In contrast, there was controversy about late abortions for social reasons and in the case of Down syndrome. Further there was strong reluctance to accept late abortion in case of minor disease. An analysis of the response patterns showed that most of the respondents had gradualist views on abortion, i.e. they would allow all early abortions, but only abortions for some reasons later in pregnancy. It was also found that the number who would find an early abortion acceptable in general was much higher than the number who would accept it in their own case. These findings suggest that a great part of the resistance towards abortion does not rest on a concern for the rights and interests for the fetus. Instead it may be explained on a view according to which fetal life is ascribed intrinsic moral value.

    The aim of this paper is to discuss the main characteristics of the scientific literature on abortion in Brazil. Data were collected from 88 literature bases, and 2,109 documents from 1987 to 2008 were retrieved. Based on the findings, the field of abortion in Brazil is dominated by female researchers affiliated with public universities and nongovernmental organizations from the Southeast, with training in health sciences. There is no research on abortion in the North, while 14% of the studies were conducted in the Northeast and 4% in the Central-West. Abortion has been a constant theme in the scientific literature in Brazil, increasing in the mid-20th century.

  8. Prenatal diagnosis, selective abortion, and the Abortion (Amendment) Bill.

    The rapid development of early prenatal diagnostic tests for some fetal malformations and abnormalities and the introduction of this approach to malformation into clinical practice in most areas of the United Kingdom has, to a great extent, been made possible by the 1967 Abortion Act. Although at least 30 of every 1000 pregnancies will end in a seriously malformed infant with reduced survival, or survival with impaired quality of life, only less than 1/3 of these abnormal fetuses are currently amenable to early antenatal detection. Yet, it has been estimated that about 10% of all pregnancies can be identified as having a risk of 1 of these detectable abnormalities of more than 1 in 100. Most prenatal diagnostic tests available at this time involve an amniocentesis, which cannot generally be carried out safely and successfully before 15 or 16 weeks' gestation. Laboratory tests on the amniotic fluid itself or on the cells it contains must follow, generally after a period of cell culture. Fetosocopy at about 18 weeks or later is at present rarely used because of its technical difficulties as well as its relatively high risk of complications. Ultrasound is largely used as a preliminary to amniocentesis or to identify anencephaly. 1 of the problems of these prenatal tests often involving lengthy laboratory techniques is reflected in the late termination times reported from 1 large center, where barely 1/2 the terminations for fetal malformations could be performed before 20 weeks' gestation. 2 provisions of John Corrie's Bill now before Parliament may have a profound effect on prenatal diagnosis and related aspects of secondary prevention of fetal malformation. These are the suggested lowering of the gestational age at which abortions can normally be performed, and the strengthening of the conscience clause enabling physicians to refuse to provide a certificate for abortion.

  9. Implementation of legal abortion in Nepal: a model for rapid scale-up of high-quality care

    PubMed Central

    2012-01-01

    Unsafe abortion's significant contribution to maternal mortality and morbidity was a critical factor leading to liberalization of Nepal's restrictive abortion law in 2002. Careful, comprehensive planning among a range of multisectoral stakeholders, led by Nepal's Ministry of Health and Population, enabled the country subsequently to introduce and scale up safe abortion services in a remarkably short timeframe. This paper examines factors that contributed to rapid, successful implementation of legal abortion in this mountainous republic, including deliberate attention to the key areas of policy, health system capacity, equipment and supplies, and information dissemination. Important elements of this successful model of scaling up safe legal abortion include: the pre-existence of postabortion care services, through which health-care providers were already familiar with the main clinical technique for safe abortion; government leadership in coordinating complementary contributions from a wide range of public- and private-sector actors; reliance on public-health evidence in formulating policies governing abortion provision, which led to the embrace of medical abortion and authorization of midlevel providers as key strategies for decentralizing care; and integration of abortion care into existing Safe Motherhood and the broader health system. While challenges remain in ensuring that all Nepali women can readily exercise their legal right to early pregnancy termination, the national safe abortion program has already yielded strong positive results. Nepal's experience making high-quality abortion care widely accessible in a short period of time offers important lessons for other countries seeking to reduce maternal mortality and morbidity from unsafe abortion and to achieve Millennium Development Goals.

    Unsafe abortion continues to be a major cause of maternal death; it accounts for 14.5% of all maternal deaths globally and almost all of these deaths occur in countries with restrictive abortion laws. A strong body of accumulated evidence shows that the simple means to drastically reduce unsafe abortion-related maternal deaths and morbidity is to make abortion legal and institutional termination of pregnancy broadly accessible. Despite this evidence, abortion is denied even when the legal condition for abortion is met. The present article aims to contribute to a better understanding that one can be in favor of greater access to safe abortion services, while at the same time not be "in favor of abortion," by reviewing the evidence that indicates that criminalization of abortion only increases mortality and morbidity without decreasing the incidence of induced abortion, and that decriminalization rapidly reduces abortion-related mortality and does not increase abortion rates.

    The importance of South Africa as a model for reproductive self-determination in Africa cannot be underestimated. Abortion has been legal since 1996, and the country has some of the most developed government systems for the provision of abortion care on the continent. Yet in the same way opponents of abortion in the United States have whittled away at access with increased bureaucracy, South Africa faces similar assaults that leave women without safe care and threaten to turn back achievements made during the past 16 years. I explore the history of the law, subsequent legal challenges, and new threats to women's access to abortion services, including service delivery issues that may influence the future of public health in the country.

    Background Tanzania has one of the highest maternal mortality ratios in the world, and unsafe abortion is one of its leading causes. Yet little is known about its incidence. Objectives To provide the first ever estimates of the incidence of unsafe abortion in Tanzania, at the national level and for each of the 8 geopolitical zones (7 in Mainland plus Zanzibar). Methods A nationally representative survey of health facilities was conducted to determine the number of induced abortion complications treated in facilities. A survey of experts on abortion was conducted to estimate the likelihood of women experiencing complications and obtaining treatment. These surveys were complemented with population and fertility data to obtain abortion numbers, rates and ratios, using the Abortion Incidence Complications Methodology. Results In Tanzania, women obtained just over 405,000 induced abortions in 2013, for a national rate of 36 abortions per 1,000 women age 15–49 and a ratio of 21 abortions per 100 live births. For each woman treated in a facility for induced abortion complications, 6 times as many women had an abortion but did not receive care. Abortion rates vary widely by zone, from 10.7 in Zanzibar to 50.7 in the Lake zone. Conclusions The abortion rate is similar to that of other countries in the region. Variations by zone are explained mainly by differences in fertility and contraceptive prevalence. Measures to reduce the incidence of unsafe abortion and associated maternal mortality include expanding access to post-abortion care and contraceptive services to prevent unintended pregnancies.

    In the Relativistic Heavy Ion Collider (RHIC) the abort kicker magnets are the limiting aperture. Continuous losses at this location could deteriorate the kicker performance. In addition, losses especially in the triplet area cause backgrounds in the experimental detectors. The RHIC one-stage collimation system was used to reduce these backgrounds as well as losses at the abort kickers. Collimation performance and results from various runs with even and uneven species (Au-Au, pp and d-Au) are presented and compared. Upgrades of the system for the upcoming high luminosity runs are outlined.

    2011-01-01

    Launch vehicle ascent is a time of high risk for an on-board crew. There are many types of failures that can kill the crew if the crew is still on-board when the failure becomes catastrophic. For some failure scenarios, there is plenty of time for the crew to be warned and to depart, whereas in some there is insufficient time for the crew to escape. There is a large fraction of possible failures for which time is of the essence and a successful abort is possible if the detection and action happens quickly enough. This paper focuses on abort determination based primarily on data already available from the GN&C system. This work is the result of failure analysis efforts performed during the Ares I launch vehicle development program. Derivation of attitude and attitude rate abort triggers to ensure that abort occurs as quickly as possible when needed, but that false positives are avoided, forms a major portion of the paper. Some of the potential failure modes requiring use of these triggers are described, along with analysis used to determine the success rate of getting the crew off prior to vehicle demise.

  16. Informed or Misinformed Consent? Abortion Policy in the United States.

    2016-04-01

    Since 2010, the United States has witnessed a dramatic expansion of state-based restrictions on abortion. The most common of these are informed consent statutes, which require that a woman seeking an abortion receive a state-authored informational packet before the abortion procedure can be performed. These laws, in addition to requiring the provision of information about alternatives to and risks of abortion, all also require details of embryological and fetal development. This article presents the findings of a comprehensive study of state-authored informed consent materials regarding embryological and fetal development. To conduct this study, we recruited a panel of experts in human anatomy to assess the accuracy of these materials in the context of the constitutional standard established inPlanned Parenthood of Southeastern Pennsylvania et al. v. Robert P. Casey et al.(505 U.S. 833 (1992)): that such information must be "truthful" and "nonmisleading." We find that nearly one-third of the informed consent information is medically inaccurate, that inaccurate information is concentrated primarily in the earlier weeks of pregnancy and is clustered around particular body systems. We discuss the implications of our findings for the question of the constitutionality of informed consent laws as they have been implemented in practice. PMID:26732319

    2008-05-01

    Screening for fetal anomalies in the second trimester of pregnancy is increasingly becoming a part of antenatal care. As a consequence, more pregnant women are learning that the child they are expecting has an anomaly. This article derives from anthropological research in a hospital in Hanoi, Viet Nam, from 2003-2006 that investigated 30 women's experiences after a fetal anomaly was detected. We followed the women from the ultrasound scan through the process of deciding whether to continue their pregnancy or have an abortion. This article focuses on the 17 women who had an abortion and the support they received from health care providers. Their loss of a wanted pregnancy led to feelings of guilt, pain and sadness and fear and uncertainty about being able to have a healthy baby in the future. Two years after the abortion, most of the women had come to terms with the loss, especially those who had had a healthy child since. We recommend that the Vietnamese health care system seeks to ensure that women receive counselling and support that answers their questions about what happened and why. To do this, health care staff need additional training in fetal medicine and counselling skills and sensitisation to the social and emotional challenges that detection of fetal anomalies and second trimester abortion bring to antenatal care.

    One of NASAs challenges for the Orion vehicle is the control system design for the Launch Abort Vehicle (LAV), which is required to abort safely at any time during the atmospheric ascent portion of ight. The focus of this paper is the gain design and scheduling process for a controller that covers the wide range of vehicle configurations and flight conditions experienced during the full envelope of potential abort trajectories from the pad to exo-atmospheric flight. Several factors are taken into account in the automation process for tuning the gains including the abort effectors, the environmental changes and the autopilot modes. Gain scheduling is accomplished using a linear quadratic regulator (LQR) approach for the decoupled, simplified linear model throughout the operational envelope in time, altitude and Mach number. The derived gains are then implemented into the full linear model for controller requirement validation. Finally, the gains are tested and evaluated in a non-linear simulation using the vehicles ight software to ensure performance requirements are met. An overview of the LAV controller design and a description of the linear plant models are presented. Examples of the most significant challenges with the automation of the gain tuning process are then discussed. In conclusion, the paper will consider the lessons learned through out the process, especially in regards to automation, and examine the usefulness of the gain scheduling tool and process developed as applicable to non-Orion vehicles.

    The 50 states of the US were compared in 1971-72 and 1974-75 with respect to percentage apparent conceptions aborted and infant mortality rates attributed to various causes. Only nonvehicle accidental deaths were consistently related to abortion. The correlation is nonlinear; nonvehicle accidental deaths were especially high in states with little or no abortion. A decline in nonvehicle accidental deaths from before to after the Supreme Court decision was most pronounced in states where there were fewest abortions before the decision and where increases in abortion followed the decision.

    2015-10-01

    Unsafe abortion causes approximately 13% of all maternal deaths worldwide, with higher rates in areas where abortion access is restricted. Because safe abortion is so low risk, if all women who needed an abortion could access safe care, this rate would drop dramatically. As women's health providers and advocates, obstetrician/gynecologists can support abortion access. By delivering high-quality, evidence-based care ourselves, supporting other providers who perform abortion, helping women who access abortion in the community, providing second-trimester care, and improving contraceptive uptake, we can decrease morbidity and mortality from unsafe abortion.

    2011-10-01

    The paper analyzes conscientious objection by physicians, through the concrete situation of legal abortion in Brazil. It reviews the two main ethical frameworks about conscientious objection in public health, the incompatibility thesis and the integrity thesis, to analyze the reality of legal abortion services in the referral services of the Brazilian public health care system. From these two perspectives, a third perspective is proposed - the justification thesis, to manage the right to conscientious objection among physicians in referral services. This analysis may contribute to the organization of services for legal abortion and to the education of future physicians working in emergency obstetric care.

    2014-01-01

    We explored how low-income abortion clients in states where public funding was and was not available perceived the role of public funding for abortion. From October 2010 through February 2011, we conducted 71 semi-structured in-depth telephone interviews with low-income abortion clients in Arizona, Florida, New York, and Oregon. Women reported weighing numerous factors when determining which circumstances warranted public funding. Though most women generally supported coverage, they deviated from their initial support when asked about particular circumstances. Respondents felt most strongly that abortion should not be covered when a woman could not afford another child or was pregnant outside of a romantic relationship. Participants used disparaging language to describe the presumed behavior of women faced with unintended pregnancies. In seeking to discredit "other" women's abortions, women revealed the complex nature of abortion stigma. We propose that women's abortion experiences and subsequent opinions on coverage indicated three distinct manifestations of abortion stigma: women (1) resisted the prominent discourse that marks women who have had abortions as selfish and irresponsible; (2) internalized societal norms that stereotype women based on the circumstances surrounding the abortion; and (3) reproduced stigma by distancing themselves from the negative stereotypes associated with women who have had abortions.

    Cuba's annual induced abortion rate persistently ranks among the highest in the world, and abortion plays a prominent role in Cuban fertility regulation despite widespread contraceptive prevalence and state promotion of modern contraceptives. We explore this phenomenon using the concept of an "abortion culture," typically used in reference to Soviet and post-Soviet countries. We synthesize existing literature to provide a historical account of abortion and contraception in Cuba. We also provide a qualitative analysis of abortion and contraceptive use based on in-depth interviews conducted in 2005 in Havana with 24 women who have had an abortion and 10 men whose partners have had an abortion. Information gained from a focus-group discussion with medical professionals also informed the study. Our four principal findings are: (a) longstanding awareness of abortion, (b) the view of abortion as a personal decision, (c) the influence of economic constraints on the decision to induce an abortion, and (d) general skepticism toward contraceptives. We discuss our results on abortion in Cuba in relation to the notion of social diffusion, an approach commonly used to explain the spread of fertility control throughout a population.

Positive emotions, constituting the third factor, were experienced most strongly. Correlations with background variables suggest two influences on response: the woman's social environment and her internalized concerns about the abortion.

    Ethical investment funds have traditionally boycotted the arms industry, companies known to pollute the environment, and those involved in animal research. However, recent newspaper reports suggest that some investment funds plan to also boycott hospitals and pharmaceutical companies involved in abortion-related activities. Ethical Financial, anti-abortion independent financial advisors, are encouraging a boycott of investment in private hospitals and manufacturers of equipment involved in abortions, and pharmaceutical firms which produce postcoital contraception or conduct embryo research. Ethical Financial claims that Family Assurance has agreed to invest along anti-abortion lines, Aberdeen Investment is already boycotting companies linked to abortion, and Hendersons ethical fund plans to follow suit. There is speculation that Standard Life, the largest mutual insurer in Europe, will also refuse to invest in abortion-related concerns when it launches its ethical fund in the spring. Managers of ethical funds should, however, understand that, contrary to the claims of the anti-choice lobby, there is extensive public support for legal abortion, emergency contraception, and embryo research. Individuals and institutions which contribute to the development of reproductive health care services are working to alleviate the distress of unwanted pregnancy and infertility, laudable humanitarian goals which should be encouraged. Those who try to restrict the development of abortion methods and services simply show contempt for women, treating them as people devoid of conscience who are incapable of making moral choices.

    2012-10-01

    Unsafe abortion is one of the main causes of maternal mortality and severe morbidity in countries with restrictive abortion laws. In 2007, the International Federation of Gynecology and Obstetrics (FIGO) created a Working Group on the Prevention of Unsafe Abortion and its Consequences (WGPUA). This led to a FIGO initiative with that aim which has the active participation of 43 FIGO member societies. The WGPUA has recommended that the plans of action of the countries participating in the initiative consider several levels of prevention shown to have the potential to successfully reduce unsafe abortions: (1) primary prevention of unintended pregnancy and induced abortion; (2) secondary prevention to ensure the safety of an abortion procedure that could not be avoided; (3) tertiary prevention of further complications of an unsafe abortion procedure that has taken place already, through high-quality postabortion care; and (4) quaternary prevention of repeated abortion procedures through postabortion family planning counseling and contraceptive services. This paper reviews these levels of prevention and the evidence that they can be effective.

    PubMed

    2002-05-01

    Thanks to initiatives since 1994, most reproductive health programmes for refugee women now include family planning and safe delivery care. Emergency contraception and post-abortion care for complications of unsafe abortion are recommended, but provision of these services has lagged behind, while services for women who wish to terminate an unwanted pregnancy are almost non-existent. Given conditions in refugee settings, including high levels of sexual violence, unwanted pregnancies are of particular concern. Yet the extent of need for abortion services among refugee women remains undocumented. UNFPA estimates that 25-50% of maternal deaths in refugee settings are due to complications of unsafe abortion. Barriers to providing abortion services may include internal and external political pressure, legal restrictions, or the religious affiliation of service providers. Women too may be pressured to continue pregnancies and are often unable to express their needs or assert their rights. Abortion advocacy efforts should highlight the specific needs of refugee women and encourage provision of services where abortion is legally indicated, especially in cases of rape or incest, and risk to a woman's physical and mental health. Implementation of existing guidelines on reducing the occurrence and consequences of sexual violence in refugee settings is also important. Including refugee women in international campaigns for expanded access to safe abortion is critical in addressing the specific needs of this population. PMID:12369319

  14. Abortion and nursing: a legal update.

    PubMed

    Horsley, J

    1992-12-01

    Almost 2 decades after the Supreme Court's landmark decision in Roe v. Wade, nurses' refusal to assist in abortions is still in question. There are about 1.6 million abortions a year. If Congress passes the Freedom of Choice Act, American women will be guaranteed continued access to abortion. But the effect of new regulations on 2 million nurses is the issue. Title VI of the Civil Rights Act of 1964 protects those who refuse to participate in abortions because of their religious beliefs. Several states have also enacted laws giving the right to health care workers to refuse to participate on ethical grounds. In Florida a staffer at an ambulatory care center was demoted after refusing to assist in an abortion. The appeals court ruled in the nurse's favor, stating that she should have been given a different assignment. Nurses who oppose abortion are advised by attorneys not to accept jobs where they are likely to be expected to assist in them. A New York City nurse refused to assist in an abortion and was reassigned to an administrative position, which she contested. The arbitrator restored her to her original position indicating that if the Freedom of Choice Act is passed it will not eliminate a nurse's right not to assist. In 1988 the so-called gag rule was issued barring caregivers at 4000 federally funded family planning clinics serving nearly 5 million women/year from recommending abortion to patients.

Many people investigating the situation feel that the issues of pro-life and pro-choice are not central. What is most important is the fact that these bogus clinics are able to attract people who think they can obtain abortions when in fact these facilities do not offer such services. The staff at the bogus clinics have been reported to detain, harass, and coerce women who want to have abortions. They often show graphic films and employ psychological pressure in an attempt to convince the woman not to have an abortion. The Pearson Foundation published a 93 page manual titled, "How to Start and Operate Your Own Pro-Life Crisis Pregnancy Center". The manual outlines all the steps and procedures necessary to run an operation committed into deceiving women into thinking they offer abortion services. So far, proposed legislation would either require Yellow Pages publishers to list abortion alternatives and abortion services separately, or make facilities that do not provide abortions declare it in a disclaimer. However, federal authority in this situation is unclear. other proposals would give the FTC control of non-profits, or only deceptive non-profits.

  20. Abortion 1982: the Supreme Court once again.

    Clearly, abortion in the US continues to be a major medico-legal issue which will not go away. 5 major abortion cases are scheduled for review by the US Supreme Court during its 1982-83 term. Taken together, these 5 cases challenge several of the key conclusions of the Court's review of the abortion question. The primary focus of the cases is the state's power to regulate the abortion decision during the 1st and 2nd trimester of the pregnancy. 2 cases involve ordinances passed by the City of Akron regulating access to abortion in areas such as consent and notification requirements and the location of abortions after the 1st trimester. 2 of the cases involve a Missouri statute also dealing with the requirement that abortions after the 1st trimester be performed in a hospital. The final case involves a Virginia criminal prosecution of a physician accused of violating the state's requirement of in-hospital performance of a 2nd trimester abortion. In the case of Roe v. Wade, the Court had established the "trimester trilogy" governing state regulation of the abortion procedure. For the stage of the pregnancy prior to the end of the 1st trimester, the Court held that the abortion decision and its effectuation must be left to the medical judgment of the pregnant women's attending physician. For the stage of the pregnancy subsequent to the end of the 1st trimester, the Court ruled that the state may promote its interest in the health of the mother by regulating the abortion procedure in ways reasonably related to maternal health. For the stage of pregnancy subsequent to viability, the state may promote its interest in the potentiality of human life by regulation, even prohibiting abortion, except where it is necessary to preserve the mother's life or health. These 5 cases challenge the role of the Court in determining the scope of appropriate state regulation at various stages of the pregnancy.

    In this very short but fiery and violent paper against abortion the author states that most women seeking abortion are actually lying to themselves, pretending they want something which, in reality, they do not want, i.e. an abortion. The laws regulating abortion in most countries are such that a woman is practically forbidden to make an independent decision, despite, or because of the number of counseling sessions and of meetings with doctors that she must go through. Radio, television, newspapers and magazines, friends and relatives, all contribute to make of abortion a run-of-the-mill operation, while it should be seen as scandal, and as the total negation of any maternal instinct.

    Although abortion for health reasons is not considered a crime in Peru, the State does not allow its inclusion in public policy, thus violating women's right to terminate a pregnancy when it affects their health. When examining the article in the Criminal Code which decriminalizes this type of abortion, provisions are identified which protect women and set the conditions to offer this type of service. This document sets the debate about the arguments used by the Peruvian State for not approving a therapeutic abortion protocol which would regulate the provision and financing of therapeutic abortion in public services, and explains why this obligation should be complied with, based on the conceptual framework of "health exception" In addition, it presents two cases brought before the judicial court in which the Peruvian State was found guilty of violating the human rights of two adolescents to whom a therapeutic abortion was denied.

    Controversy still surrounds abortion and abortion care in many countries. Information for women who seek abortion is not always as objective and complete as desired. In Italy abortion has been legal for the last decades. The overall purpose of this study was to investigate general information needs among patients in a hospital in Rome. A questionnaire concerning information needs, opinions on information to include in a booklet, and methods of information was distributed among 212 women in a public hospital in Rome. Women answered the questionnaire very differently, and general information needs were not shown to be as essential as expected; their present needs seemed especially underestimated. However, a booklet with information as objective and complete as possible is suggested as a way of giving information to abortion patients.

    While the medical abortion (MA) drugs, mifepristone and misoprostol, have radically altered reproductive health practices around the world, there has been little field research on the sales and use of these drugs, especially in developing countries. This leaves the family planning community with many unanswered questions. While good profiles of contraceptive use are available for many countries and we have good technical data on the MA drugs' efficacy, dosages and regimens such as home dosage of misoprostol versus clinic dosage, we have very little information about the quantities of MA drugs sold, how they are used, where they are used, and, in the case of misoprostol, for what purposes. Sales data are available from one excellent commercial survey and from social marketing sales of mifepristone and misoprostol and these are presented. Acknowledging the sensitivity of the issue, especially in countries where abortion is severely restricted, the author makes a plea for careful additional research to shed light on an important and growing part of the international reproductive health picture.

    Despite laws permitting legal abortions, death due to illegal procedures sometimes occurs. One such case is described. On Aug. 26, 1969, a 65 year old Mrs. B.K. reported the rapid death of a young woman in her home. The cause of death could not be determined by topical exam. Mrs. B.K. said the young woman had come to her requesting an abortion, but became ill during the ensuing conversation. She denied doing anything to the young woman other than attempting to revive her. She said she called for help when her efforts failed. Because Mrs. B.K. had a previous criminal record for performing illegal abortions, because spots of the victims blood were found on her clothing, because spots of blood were also found on the victim though external genitals were suspiciously clean (as was the kitchen floor on which the victim was lying), an autopsy was performed. During the autopsy, a massive air embolism in the lungs was found. The air entered the circulatory system during perforation of the cervix and part of the uterus. Damage to surrounding tissues was also found. It was determined that the damage was caused by a blunt instrument. The 4 month old fetus and anmiotic sac were not damaged. Bubbles of air and coagulated blood were found in the damaged tissues. Mrs. B.K. than admitted to trying to induce the abortion by inserting a rubber tube into the uterus through the cervix, and blowing air into and out of the uterus. She had admitted to using this method in 1943 and 1954, when she was criminally prosecuted. She began performing abortions during World War 2 and had performed a great many of them since then.

  6. If war is "just," so is abortion.

    Currently Catholic bishops are applying an inconsistent ethical paradigm to the issues of war and abortion. Based on the seamless garment theory war, abortion and capital punishment are all immoral acts because they are of the same garment. They are all "killing acts" and as such they are immoral. However there is within the Catholic paradigm the idea of a just war. The just war theory states that the destruction of human life in war is justified if it is for a greater good. However abortion has no exceptions, there is no just abortion in the rules of the Catholic Church. The author takes the just war doctrine as presented by the Catholic Church and shows how it could easily apply to abortion. Both war and abortion involve the taking of a human life, but in the case of war the taking of a life is justified if it is done to protect your own life. The same exception in abortion would be to allow abortion when the mother's life is in danger. yet no such exception exists. The just war theory further states that was is necessary to protect national integrity, particularly if the violation erodes the quality of life for its citizens. The same exception for abortion would include allowing abortions for women who already have more children then they can care for or if having the child would erode the quality of life for the woman. Other aspects of the just war theory include the competence and goals of the national leaders. Women must also be allowed to be competent moral agents. Proponents of the seamless garment theory will bring up the fact that in a just war only combatants die yet the fetus is innocent. But no war has ever been fought without the loss of innocent civilians.

    Background: Skewed male:female ratios at birth have been observed among certain immigrant groups. Data on abortion practices that might help to explain these findings are lacking. Methods: We examined 1 220 933 births to women with up to 3 consecutive singleton live births between 1993 and 2012 in Ontario. Records of live births, and induced and spontaneous abortions were linked to Canadian immigration records. We determined associations of male:female infant ratios with maternal birthplace, sex of the previous living sibling(s) and prior spontaneous or induced abortions. Results: Male:female infant ratios did not appreciably depart from the normal range among Canadian-born women and most women born outside of Canada, irrespective of the sex of previous children or the characteristics of prior abortions. However, among infants of women who immigrated from India and had previously given birth to 2 girls, the overall male:female ratio was 1.96 (95% confidence interval [CI] 1.75–2.21) for the third live birth. The male:female infant ratio after 2 girls was 1.77 (95% CI 1.26–2.47) times higher if the current birth was preceded by 1 induced abortion, 2.38 (95% CI 1.44–3.94) times higher if preceded by 2 or more induced abortions and 3.88 (95% CI 2.02–7.50) times higher if the induced abortion was performed at 15 weeks or more gestation relative to no preceding abortion. Spontaneous abortions were not associated with male-biased sex ratios in subsequent births. Interpretation: High male:female ratios observed among infants born to women who immigrated from India are associated with induced abortions, especially in the second trimester of pregnancy.

    Despite the ascent of Bill Clinton to Presidential power in the US and his early successful repeals of bans on abortion counseling at federally funded clinics, abortions in military hospitals, and fetal tissue research, the controversy and debate over a woman's right to abortion continues in the US. The Hyde Amendment, named after Representative Henry Hyde, Republican from Illinois, has been in effect since 1976 barring Medicaid from funding abortions except to save the life of the pregnant woman. Congress in 1993, however, eased the amendment to allow states to use Medicaid funds to pay for abortions for low-income women in the cases of rape or incest. Anti-abortion lawmakers were assured by the provision's sponsors that the Clinton Administration would not force states to comply. The Department of Health and Human Services (HHS) instead sent a letter to state Medicaid directors on December 28, 1993, ordering them to use Medicaid funds to pay for abortions for low-income women who were the victims of rape or incest. President Clinton subsequently complained that HHS had bypassed his office in issuing the directive, state Medicaid directors protested that the directive had been imposed without the usual notice and allowance of time for public comment, and states claimed that the order clashes with existing state laws which ban the public funding of abortions not required to save the life of the mother. Officials from Arkansas, Colorado, North Dakota, Pennsylvania, and Utah have stated that they may fight the directive, while the HHS will most likely not move to rescind or change its directive. The issue will probably be resolved in the courts. The authors note that this state/federal battle over Medicaid-funded abortions is only part of a larger war scheduled to take place in Congress over whether pregnancy-related services, including abortion, will be covered in the Administration's Health Security Act.

    Although there is no right to abort in English law but rather abortion is a crime, the lawful grounds for which are instantiated in the Abortion Act 1967 (as amended by the Human Fertilisation and Embryology Act 1990), the regulation of abortion is sometimes perceived as being fairly ‘liberal’. Accordingly, the idea that aspects of English law could be criticised under the European Convention on Human Rights, with which the UK must comply following the Human Rights Act 1998, may seem unlikely. Indeed, English law is compatible with the consensus amongst contracting states that abortion should be available on maternal health grounds. However, analysis of the UK's negative obligations under Article 8 shows that section 1(1)(a) of the Act is problematic as it operates in the first trimester. Further, given the European Court of Human Rights' emphasis on the reduced margin of appreciation once a state has legalised abortion to some degree and its jurisprudence relating to a state's positive obligations, the analysis shows that, while English law may not be problematic in relation to the lack of guidelines relating to the lawful grounds for abortion, it may well be in relation to the lack of a formal system for the review of any two doctors' decision not to grant a termination. Notwithstanding the morally serious nature of the decision to abort, the analysis overall raises questions about the need for at least some degree of abortion law reform, particularly in relation to the first trimester, towards a more autonomy-focused, though time-limited, rights-based approach.

    OBJECTIVE To examine characteristics and causes of legal induced abortion–related deaths in the United States between 1998 and 2010. METHODS Abortion-related deaths were identified through the national Pregnancy Mortality Surveillance System with enhanced case-finding. We calculated the abortion mortality rate by race, maternal age, and gestational age and the distribution of causes of death by gestational age and procedure. RESULTS During the period from 1998–2010, of approximately 16.1 million abortion procedures, 108 women died, for a mortality rate of 0.7 deaths per 100,000 procedures overall, 0.4 deaths for non-Hispanic white women, 0.5 deaths for Hispanic women, and 1.1 deaths for black women. The mortality rate increased with gestational age, from 0.3 to 6.7 deaths for procedures performed at 8 weeks or less and at 18 weeks or greater, respectively. A majority of abortion-related deaths at 13 weeks of gestation or less were associated with anesthesia complications and infection, whereas a majority of abortion-related deaths at more than 13 weeks of gestation were associated with infection and hemorrhage. In 20 of the 108 cases, the abortion was performed as a result of a severe medical condition where continuation of the pregnancy threatened the woman’s life. CONCLUSION Deaths associated with legal induced abortion continue to be rare events—less than 1 per 100,000 procedures. Primary prevention of unintended pregnancy, including those in women with serious pre-existing medical conditions, and increased access to abortion services at early gestational ages may help to further decrease abortion-related mortality in the United States.

    1991-03-01

    Induced abortion is an urgent public health problem that can be controlled if it is approached in its true complexity and with a social and humanist perspective. Induced abortion has been discussed in Chile since the last century, but not always openly. Abortion is not just an individual and collective medical problem, it is also an ethical, religious, legal, demographic, political, and psychological problem. Above all it is a problem of human rights. In the past 60 years, more than 50 countries representing 76% of the world population have liberalized their abortion legislation. Around 980 million women have some degrees of access of legal abortion. The magnitude of illegal abortion is difficult to determine because of the desire of women to hide their experiences. Estimates of the incidence of abortion in Chile made some 25 years ago are no longer valid because of the numerous social changes in the intervening years. The number of abortions in Chile in 1987 was estimated using an indirect residual method at 195,441, of which 90%, or 175,897, were induced. By this estimate, 38.8% of pregnancies in Chile end in abortion. Data on hospitalizations for complications of induced abortion show an increase from 13.9/1000 fertile aged women in 1940 to 29.1 in 1965. By 1987, with increased contraceptive usage, the rate declined to 10.5 abortions per 1000 fertile aged women. The cost of hospitalization for abortion complications in 1987, despite the decline, was still estimated at US $4.3 million, a large sum in an era of declining health resources. The problem of induced abortion can be analyzed by placing it in the context of elements affecting the desire to control fertility. 4 complexes of variables are involved: those affecting the supply of contraceptive, the demand for contraceptives, the various costs of fertility control measure, and alternatives to fertility control for satisfying various needs. The analysis is further complicated when efforts are made to

    Topics of interest to women were discussed at a 1-day conference. 85% of the participants were women. The theme was, "Can the abortion rate be changed?" The number of abortions rose from 19,919 in 1985 to 21,199 in 1988, a rate of 6%. The previous 8 years had shown a steady decrease from 25,662 in 1977. This was especially pronounced in women under 25. The birth rate climbed 10% at the same time. With the exception of Ireland, free access to abortion is the rule in the majority of the countries of Europe. Prenatal diagnosis (PD)--chorionic villus biopsies and amniocentesis--was begun in 1970 in Denmark. Investigation of placental biopsies was begun in 1983. The number of diagnoses rose sharply after this. From 1980-1988 the number of legally induced abortions was between 20,000 and 23,000. The number of spontaneous abortions rose from 8000 to over 9000. There were approximately 70 abortions because of PD. This figure reached 133 in 1980. Women aged 35 and above have made increasing use of PD. After PD was brought about, the number of legal abortions dropped. 42% of pregnant women over 35 carried to term;l 46% chose legal abortion. In the 40-year age group, the figures were 23% and 60%, respectively. Data on 140 abortion seekers (AS) (ages 16-21) in Denmark (73.6% replied) were compared to 201 sexually active youngsters who were not pregnant. The abortion seekers showed no difference from those not pregnant. However, more among the AS had started sexual intercourse with the 1st 2 years after menarche; they had had many different sexual partners. 73.9% of the AS used contraception at 1st intercourse, compared to 82.1% of those not pregnant. In the abortion-seeking group, about 1/3 became pregnant despite the use of contraception (generally a condom). 44% had most recently used a pill. In 1973, a law was passed permitting abortion before the end of the 12th week of pregnancy. In the last 17 years, abortions have become more frequent among young career women. The

    Background. Induced abortion contributes significantly to maternal mortality in developing countries yet women still seek repeat induced abortion in spite of availability of contraceptive services. The aim of this study is to determine the rate of abortion and contraceptive use among women seeking repeat induced abortion in Western Nigeria. Method. A prospective cross-sectional study utilizing self-administered questionnaires was administered to women seeking abortion in private hospitals/clinics in four geopolitical areas of Ogun State, Western Nigeria, from January 1 to December 31 2012. Data were analyzed using SPSS 17.0. Results. The age range for those seeking repeat induced abortion was 15 to 51 years while the median age was 25 years. Of 2934 women seeking an abortion, 23% reported having had one or more previous abortions. Of those who had had more than one abortion, the level of awareness of contraceptives was 91.7% while only 21.5% used a contraceptive at their first intercourse after the procedure; 78.5% of the pregnancies were associated with non-contraceptive use while 17.5% were associated with contraceptive failure. The major reason for non-contraceptive use was fear of side effects. Conclusion. The rate of women seeking repeat abortions is high in Nigeria. The rate of contraceptive use is low while contraceptive failure rate is high. PMID:26078881

    There is a very small correlation, if any, between the prior use of OCs and congenital malformations, including Down's syndrome. There are few, if any, recent reports on masculinization of a female fetus born to a mother who took an OC containing 1 mg of a progestogen during early pregnancy. However, patients suspected of being pregnant and who are desirous of continuing that pregnancy should not continue to take OCs, nor should progestogen withdrawal pregnancy tests be used. Concern still exists regarding the occurrence of congenital abnormalities in babies born to such women. The incidence of postoperative infection after first trimester therapeutic abortion in this country is low. However, increasing numbers of women are undergoing repeated pregnancy terminations, and their risk for subsequent pelvic infections may be multiplied with each succeeding abortion. The incidence of prematurity due to cervical incompetence or surgical infertility after first trimester pregnancy terminations is not increased significantly. Asherman's syndrome may occur after septic therapeutic abortion. The pregnancy rate after treatment of this syndrome is low. The return of menses and the achievement of a pregnancy may be slightly delayed after OCs are discontinued, but the fertility rate is within the normal range by 1 year. The incidence of postpill amenorrhea of greater than 6 months' duration is probably less than 1%. The occurrence of the syndrome does not seem to be related to length of use or type of pill. Patients with prior normal menses as well as those with menstrual abnormalities before use of OCs may develop this syndrome. Patients with normal estrogen and gonadotropin levels usually respond with return of menses and ovulation when treated with clomiphene. The rate for achievement of pregnancy is much lower than that for patients with spontaneous return of menses. The criteria for defining PID or for categorizing its severity are diverse. The incidence of PID is higher

    In 1980 and 1981, there were 446,430 legal abortions performed in Italy. There were about 345 legal abortions per 1,000 live births in 1980 and 363 in 1981. About 1.6 percent of women aged 15-49 obtained abortions in both years. An analysis of the characteristics of Italian women who obtained abortions indicates that most were married (about 70 percent), aged 18-36 (74 percent), had had less than a high school education (74 percent) and had had at least one previous live birth (70-75 percent). In 1981, 88 percent of abortions were obtained in public hospitals; 58 percent were carried out at eight or fewer weeks of gestation; and 78 percent were performed under general anesthesia. Only 20 percent were performed without an overnight stay in the hospital; and over 40 percent of women were hospitalized for two days or longer. Infection after the abortion was reported in only 0.03 percent of cases in 1981, and hemorrhage was reported in only 0.27 percent. In 1981, between 43 percent and 84 percent of gynecologists (depending on the region of the country) declined to perform abortions on grounds of conscience. PMID:3872230

    On November 26-28, 1992, the Latin American and Caribbean Women's Health Network convened a meeting in Uruguay entitled, "Abortion in Latin America: Perspectives and Strategies." The first session was devoted to discussion of a paper that argues that a feminist ethic must be developed to counteract the dominant patriarchal ethic, which fails to improve women's lives. The next session covered the World Bank's concerns about the economic consequences of illegal abortion. The third session included descriptions of the experiences of the coordinator of the Sao Paulo Municipal Women's Health Program and of the new Argentine National Women's Health Network. Debate and discussion were generated by the next speaker, who presented a legislative proposal for the decriminalization of abortion in Latin America and noted that restrictive policies, which have failed to reduce abortion rates, will be difficult to change. It was proposed that regional campaigns be launched to legalize abortion as a first step in achieving reproductive rights for women. After a review of abortion-related activities in the region during the past year, participants composed a five-year plan of action in the areas of research, data centralization, petition campaigns, and publication of a review of abortion legislation. Finally, it was proposed that a counselor training course in sexual and reproductive rights be developed. PMID:12179717

    1992-11-01

    Abortion has been illegal in Ireland since 1861. This position was written into the national Constitution in 1963 and reconfirmed by referendum in 1983. Contraception is also illegal in the country. The pregnancy of a 14-year old adolescent due to an alleged rape, however, has caused many in Ireland to voice their support for abortion in limited circumstances. Approximately 5000 pregnant women go from Ireland to the United Kingdom annually for abortions. This 14-year old youth also planned to make the crossing, but was blocked from leaving by the Irish police and later by an injunction of the Attorney-General. The Irish Supreme Court upheld the injunction even though the young woman was reportedly contemplating suicide. A national outcry ensued with thousands of demonstrators marching in Dublin to demand the availability of information on abortion and that Irish women be allowed to travel whenever and wherever they desire. 66% of respondents to recent public opinion polls favor abortion in certain circumstances. Ultimately, the Irish Supreme Court reversed their stance to allow pregnant Irish women to travel internationally and gave suicidal Irish women the right to abortions. These decisions were made shortly within the time frame needed for the young lady in question to received a legal abortion in the United Kingdom.

    On July 7 (1995), the cabinet of Spain's socialist prime minister Felipe Gonzalez approved a measure to expand the country's abortion law by permitting a woman to obtain the procedure during the first 12 weeks of pregnancy in circumstances not currently allowed. Since 1985, abortion has been legal throughout pregnancy in the following situations: when a medical specialist not associated with the procedure determines that an abortion is necessary to "avert a serious risk to [a woman's] physical or mental health;" during the first 12 weeks if the pregnancy results from reported rape; and within the first 22 weeks when two physicians not associated with the abortion certify that the fetus would develop "severe physical or mental defects." The new legislation, which also requires women to receive nonbinding counseling, permits abortions when a health care professional determines that carrying to term will cause a woman severe anxiety for social or economic reasons. Before the measure can become law, it must be approved by the Spanish Parliament, which is expected to vote on the proposal in September. The Catalan nationalist grouping, which has been a key supporter of the socialist government, is among the forces opposing liberalization of the abortion statute. Partly due to the abortion controversy, the Catalan coalition is expected to vote on July 17 to decide whether to continue its backing.

  1. Abortion stigma: a reconceptualization of constituents, causes, and consequences.

    Stigmatization is a deeply contextual, dynamic social process; stigma from abortion is the discrediting of individuals as a result of their association with abortion. Abortion stigma is under-researched and under-theorized, and the few existing studies focus only on women who have had abortions. We build on this work, drawing from the social science literature to describe three groups whom we posit are affected by abortion stigma: Women who have had abortions, individuals who work in facilities that provide abortion, and supporters of women who have had abortions, including partners, family, and friends, as well as abortion researchers and advocates. Although these groups are not homogeneous, some common experiences within the groups--and differences between the groups--help to illuminate how people manage abortion stigma and begin to reveal the roots of this stigma itself. We discuss five reasons why abortion is stigmatized, beginning with the rationale identified by Kumar, Hessini, and Mitchell: The violation of female ideals of sexuality and motherhood. We then suggest additional causes of abortion stigma, including attributing personhood to the fetus, legal restrictions, the idea that abortion is dirty or unhealthy, and the use of stigma as a tool for anti-abortion efforts. Although not exhaustive, these causes of abortion stigma illustrate how it is made manifest for affected groups. Understanding abortion stigma will inform strategies to reduce it, which has direct implications for improving access to care and better health for those whom stigma affects.

    Forty-six couples with at least two consecutive abortions were examined. The morphological and the functional clinical check-ups were constantly negative. In all the couples a karyotype analysis was carried out including an investigation of C and/or G bands. The phenotypes of ABO, Rh, MNSs and HLA-systems were also determined. No significant difference was observed in the distribution of ABO phenotypes between males and females, or between subjects with abortions and controls. Regarding the Rh system, the most important findings are the absence of phenotypes with the E allele in double dose, the reduction of the frequency of the CCDee phenotype and the increase in the frequency of the ccDEe phenotype. Concerning MNSs system, an increase in the frequency of the phenotypes with the S allele in double dose is observed. Females with habitual abortions show a higher incidence of Bw35 as compared both to males and to the controls. No significant differences were observed for other antigens. The persistence of a genetic disequilibrium both in the Rh and the MNSs systems suggests that the selection might act against certain antigenic combinations, independently from the state of materno-foetal compatibility. Though preliminary, our data seem to give some support to this hypothesis. They also suggest that Bw35 antigen may be important in human reproduction.

  5. The deprivation argument against abortion.

    PubMed

    Stretton, Dean

    2004-04-01

    The most plausible pro-life argument claims that abortion is seriously wrong because it deprives the foetus of something valuable. This paper examines two recent versions of this argument. Don Marquis's version takes the valuable thing to be a 'future like ours', a future containing valuable experiences and activities. Jim Stone's version takes the valuable thing to be a future containing conscious goods, which it is the foetus's biological nature to make itself have. I give three grounds for rejecting these arguments. First, they lead to unacceptable inequalities in the wrongness of killing. Second, they lead to counterintuitive results in a range of imaginary cases. Third, they ignore the role of psychological connectedness in determining the magnitude or seriousness of deprivation-based harms: because the foetus is only weakly psychologically connected to its own future, it cannot be seriously harmed by being deprived of that future.

The first of this series was the Orion Pad Abort 1 Flight-Test Vehicle, which was successfully flown on May 6, 2010 at the White Sands Missile Range in New Mexico. This report provides a brief overview of the three propulsive subsystems used on the Pad Abort 1 Flight-Test Vehicle. An overview of the propulsive systems originally planned for future flight-test vehicles is also provided, which also includes the cold gas Reaction Control System within the Crew Module, and the Peacekeeper first stage rocket motor encased within the Abort Test Booster aeroshell.

    In 1795 the Marquis de Sade published his La Philosophic dans le boudoir, in which he proposed the use of induced abortion for social reasons and as a means of population control. It is from this time that medical and social acceptance of abortion can be dated, although previously the subject had not been discussed in public in modern times. It is suggested that it was largely due to de Sade's writing that induced abortion received the impetus which resulted in its subsequent spread in western society. PMID:6990001

    Placement of an intrauterine device (IUD) immediately after a first or second trimester surgical abortion is safe and convenient and decreases the risk of repeat unintended pregnancy. Immediate postabortion IUD placement is not recommended in the setting of postprocedure hemorrhage, uterine perforation, infection, or hematometra. Otherwise, there are few contraindications to IUD placement following surgical abortion. Sexually transmitted infection screening should follow US Centers for Disease Control and Prevention guidelines. No additional antibiotics are needed beyond those used for the abortion. Placing immediate postabortion IUDs makes highly-effective long-acting reversible contraception more accessible to women. PMID:26598301

    Since the 1973 Supreme Court decision legalizing abortion, medical and scientific developments have focused greater public and professional attention on the status of the fetus. Their cumulative effect may influence legal, social, and moral thought and set the stage for a change in public opinion and a challenge to legalized abortion. There is as yet no inexorable convergence of medical data and legal opinion that would undermine the rational of Roe v. Wade. But the prochoice movement must find room for an open airing of the moral questions if abortion is to remain what it should be--a legally acceptable act.

    Infective complications following induced abortions are still a common cause of morbidity and mortality. This review focusses on defining the strategies to improve care of women seeking an induced abortion and to reduce infective complications. We have considered the evidence for screening and cost-effectiveness for antibiotic prophylaxis. Current evidence suggests that treating all women with prophylactic antibiotics in preference to screening and treating is the most cost-effective way of reducing infective complications following induced abortions. The final strategy to prevent infective complications should be individualized for each region/area depending on the prevalence of organisms causing pelvic infections and the resources available.

    This paper discusses the Brazilian Supreme Court ruling on the case of anencephaly. In Brazil, abortion is a crime against the life of a fetus, and selective abortion of non-viable fetuses is prohibited. Following a paradigmatic case discussed by the Brazilian Supreme Court in 2004, the use of abortion was authorized in the case of a fetus with anencephaly. The objective of this paper is to analyze the ethical arguments of the case, in particular the strategy of avoiding the moral status of the fetus, the cornerstone thesis of the Catholic Church.

    Twenty-five years ago, in 1989, family planning services in Britain faced a serious crisis with contentious cuts for community clinics being contemplated by health authorities. There was extensive discussion on ethical issues relating to the provision of abortion services. Social acceptance of abortion occurred in association with departure from traditional values due to the exigencies of modern life. Twenty-five years later, in 2014, abortion unfortunately continues to cause controversy in international health, despite guidance for its incorporation in comprehensive reproductive health care services.

    A nationally representative survey was conducted among 3000 Catholics in Mexico during 2009 and 2010. Respondents were presented with a hypothetical situation about a young woman who decided to have an abortion and were asked their personal opinion of her. On the basis of a stigma index, it was found that the majority (61%) had stigmatizing attitudes about abortion; however, 81% believed that abortion should be legal in at least some circumstances. Respondents were significantly more likely to stigmatize abortion if they disagreed with the Mexico City law legalizing the procedure (odds ratio 1.66; 95% CI, 1.30-2.11) and believed that abortion should be prohibited in all cases (odds ratio 3.13; 95% CI, 2.28-4.30). Such stigma can lead women to seek unsafe abortions to avoid judgment by society.

    2013-01-01

    Objective To evaluate the implementation of state Medicaid abortion policies and the impact of these policies on abortion clients and abortion providers. Data Source From 2007 to 2010, in-depth interviews were conducted with representatives of 70 abortion-providing facilities in 15 states. Study Design In-depth interviews focused on abortion providers' perceptions regarding Medicaid and their experiences working with Medicaid and securing reimbursement in cases that should receive federal funding: rape, incest, and life endangerment. Data Extraction Data were transcribed verbatim before being coded. Principal Findings In two study states, abortion providers reported that 97 percent of submitted claims for qualifying cases were funded. Success receiving reimbursement was attributed to streamlined electronic billing procedures, timely claims processing, and responsive Medicaid staff. Abortion providers in the other 13 states reported reimbursement for 36 percent of qualifying cases. Providers reported difficulties obtaining reimbursement due to unclear rejections of qualifying claims, complex billing procedures, lack of knowledgeable Medicaid staff with whom billing problems could be discussed, and low and slow reimbursement rates. Conclusions Poor state-level implementation of Medicaid coverage of abortion policies creates barriers for women seeking abortion. Efforts to ensure policies are implemented appropriately would improve women's health. PMID:22742741

    The negative health consequences of tobacco use are well documented. Some research finds women receiving abortions are at increased risk of subsequent tobacco use. This literature has methodological problems, most importantly, inappropriate comparison groups. This study uses data from the Turnaway Study, a longitudinal study of women who all sought, but did not all receive, abortions at 30 facilities across the United States. Participants included women presenting just before an abortion facility's gestational age limit who received abortions (Near Limit Abortion Group, n = 452), just after the gestational limit who were denied abortions (Turnaways, n = 231), and who received first trimester abortions (First Trimester Abortion Group, n = 273). This study examined the association between receiving versus being denied an abortion and subsequent tobacco use over 2-years. Trajectories of tobacco use over 2 years were compared using multivariate mixed effects regression. Women receiving abortion maintained their level of tobacco use over 2 years. Women denied abortion initially had lower levels of tobacco use than women receiving abortion, but increased their tobacco use from 1 week through 12-18 months post-abortion seeking and then decreased their use by 2 years post-abortion seeking. Baseline parity modified these associations. Receiving an abortion was not associated with an increase in tobacco use over time. Overall, women who carry unwanted pregnancies to term appear to demonstrate similar cessation and resumption patterns to other pregnant women.

    This study analyzes ethnic differences in induced abortion among ever-married women in Kazakstan, drawing on data from the 1995 Kazakstan Demographic and Health Survey. Instead of conventional ethnic markers, such as "Kazak" or "Russian," it focuses on more complex ethnocultural identities that combine ascribed ethnicity with language use. Because of the history of russification in Kazakstan, three ethnocultural groups are defined and compared--Kazak women who chose to be interviewed in Kazak, Kazak women who chose to be interviewed in Russian, and women of European background interviewed in Russian. Whereas women of European origin were the most likely to undergo induced abortion, the Russian-interviewed Kazaks had higher abortion ratios and were more likely to terminate their pregnancies than were the Kazak-interviewed Kazaks, net of other characteristics. The implications of the results for induced abortion trends and family planning policy in Kazakstan are discussed in addition to other findings. PMID:9431652

  20. Induced abortion and social factors in wild horses.

    PubMed

    Berger, J

    Much evidence now suggests that the postnatal killing of young in primates and carnivores, and induced abortions in some rodents, are evolved traits exerting strong selective pressures on adult male and female behaviour. Among ungulates it is perplexing that either no species have developed convergent tactics or that these behaviours are not reported, especially as ungulates have social systems similar to those of members of the above groups. Only in captive horses (Equus caballus) has infant killing been reported. It has been estimated that 40,000 wild horses live in remote areas of the Great Basin Desert of North America (US Department of Interior (Bureau of Land Management), unpublished report), where they occur in harems (females and young) defended by males. Here I present evidence that, rather than killing infants directly, invading males induce abortions in females unprotected by their resident stallions and these females are then inseminated by the new males.

    McIntyre, R L

    1993-01-01

    The social policy towards abortion determined by the Roe vs. Wade decision can be overturned at any time depending upon how the US Supreme Court reacts to challenges to its earlier ruling. Roe vs. Wade was decided by a 7 to 2 vote, and the members of the Supreme Court appointed by Presidents Reagan and Bush were chosen to uphold a conservative (anti-abortion) ideology. Although more than half of the present Court was appointed by these presidents, President Clinton now has the opportunity to appoint 2 more Justices. The public policy positions which are currently available to the Supreme Court or to Congress can be ranked on a chart from liberal to conservative. In this article, 7 different positions are described in detail, and the public policy implications of the implementation of each position are described. The first position considered is the extreme conservative position of "no abortion; no exceptions" as defined by author and Roman Catholic theologian Gerald Kelly. The only procedures allowed which would end the life of a fetus would be those to remove an ovary or fallopian tube in the case of an extrauterine pregnancy (permissible under the doctrine of double effect). In the most extreme interpretation of this situation (which Kelly does not seem to hold), those who perform abortions would be prosecuted for murder. The next position considered is the most liberal position, which is espoused by Michael Tooley, and which holds that abortion and early infanticide are both permissible. The third position is that which allows no abortion but has limited exceptions in cases of rape or incest. The appropriate consideration for abortion presented next is that of the late Joseph Fletcher who believed that whatever love requires is the proper response to the situation. Philosopher Dan Callahan espouses the notion that abortion should be performed for compelling reasons only (after effective counseling). The trimester approach to the problem of abortion is that set

  4. Application of Fault Management Theory to the Quantitative Selection of a Launch Vehicle Abort Trigger Suite

    The theory of System Health Management (SHM) and of its operational subset Fault Management (FM) states that FM is implemented as a "meta" control loop, known as an FM Control Loop (FMCL). The FMCL detects that all or part of a system is now failed, or in the future will fail (that is, cannot be controlled within acceptable limits to achieve its objectives), and takes a control action (a response) to return the system to a controllable state. In terms of control theory, the effectiveness of each FMCL is estimated based on its ability to correctly estimate the system state, and on the speed of its response to the current or impending failure effects. This paper describes how this theory has been successfully applied on the National Aeronautics and Space Administration's (NASA) Space Launch System (SLS) Program to quantitatively estimate the effectiveness of proposed abort triggers so as to select the most effective suite to protect the astronauts from catastrophic failure of the SLS. The premise behind this process is to be able to quantitatively provide the value versus risk trade-off for any given abort trigger, allowing decision makers to make more informed decisions. All current and planned crewed launch vehicles have some form of vehicle health management system integrated with an emergency launch abort system to ensure crew safety. While the design can vary, the underlying principle is the same: detect imminent catastrophic vehicle failure, initiate launch abort, and extract the crew to safety. Abort triggers are the detection mechanisms that identify that a catastrophic launch vehicle failure is occurring or is imminent and cause the initiation of a notification to the crew vehicle that the escape system must be activated. While ensuring that the abort triggers provide this function, designers must also ensure that the abort triggers do not signal that a catastrophic failure is imminent when in fact the launch vehicle can successfully achieve orbit. That is

    It is common to think of scientific research and the knowledge it generates as neutral and value free. Indeed, the scientific method is designed to produce "objective" data. However, there are always values built into science, as historians of science and technology have shown over and over. The relevant question is not how to rid science of values but, instead, to ask which values and whose values belong? Currently, antiabortion values consistently determine US research policy. Abortion research is declared illegitimate in covert and overt ways, at the level of individual researchers and research policy broadly. Most importantly, federal policy impedes conduct of both basic and clinical research in abortion. However, it is not just research in abortion that is deemed "illegitimate;" research in infertility and in vitro fertilization is as well. Federal funding of any reproductive health research agenda that would pose more than minimal risk to a fetus or embryo is banned. This leaves unanswered scientific questions about abortion, infertility, miscarriage and contraception among other areas. Since moral ground is occupied not just by abortion opponents but also by people who support abortion rights, there is at the very least a competing moral claim to consider changing federal research funding policy. Women and families deserve access to knowledge across the spectrum of reproductive health issues, whether they seek to end or start a pregnancy. Thus, research funding is an issue of reproductive justice. PMID:23815965

    This report summarizes current knowledge about abortion in Vietnam, drawing upon government statistics, survey data, and fieldwork undertaken by the author in Vietnam throughout 1993 and part of 1994. The official total abortion rate in Vietnam in 1992 was about 2.5 per woman, the highest in Asia and worrisome for a country with a still-high total fertility rate of 3.7 children per woman. Vietnamese provinces exhibited substantial variation in both the rate of abortion and the type of procedures performed. Among the hypotheses explored to explain Vietnam's high rate of abortion are the borrowing of family planning strategies from other poor socialist states where abortion is common; current antinatal population policies that interact with a lack of contraceptive alternatives; and a rise in pregnancies among young and unmarried women in the wake of recent free-market reforms. Because family-size preferences are still declining, abortion rates may continue to increase unless the incidence of unwanted pregnancy can be reduced, a goal that Vietnamese population specialists are seeking to achieve.

    The antiabortion groups and their lawyers have added a new weapon to their arsenal against physicians who perform abortions in the US: malpractice lawsuits. The nonprofit educational organization Life Dynamics generates material for personal injury lawyers and is participating in 80 cases. It has assembled 642 lawyers and 500 physicians in its abortion malpractice program. Life Dynamics calls for persons to support lawsuits to increase malpractice insurance rates of abortionists, thereby forcing them out of business. Its 2-day 1994 seminar in Texas addressed abortion injuries, an alleged link between abortion and breast cancer, and abortion as a likely source of post-traumatic stress disorder. A lawyer and general counsel of the Arizona Right-to-Life has filed two lawsuits against a Phoenix physician who performs abortion. The trial judge dismissed both cases and fined the lawyer for frivolous lawsuits. An appeal overturned the fines. The lawyer has three more lawsuits on the docket. The physician had complained to the Arizona Bar Association about the lawyer. Even though the physician's insurance company did not pay any claims, its underwriters deemed him an actuarial risk, thereby making him essentially uninsurable. Local medical associations have failed to take a position on the lawyer's legal misconduct because they do not want to alienate some members. The Planned Parenthood Federation of America agreed that the lawsuits brought against the Phoenix physician were fraudulent and that they do not aim to protect women but to revoke their right to choose.

    Background Incorrect knowledge of laws may affect how women enter the health system or seek services, and it likely contributes to the disconnect between official laws and practical applications of the laws that influence women’s access to safe, legal abortion services. Objective To provide a synthesis of evidence of women’s awareness and knowledge of the legal status of abortion in their country, and the accuracy of women’s knowledge on specific legal grounds and restrictions outlined in a country’s abortion law. Methods A systematic search was carried for articles published between 1980–2015. Quantitative, mixed-method data collection, and objectives related to women’s awareness or knowledge of the abortion law was included. Full texts were assessed, and data extraction done by a single reviewer. Final inclusion for analysis was assessed by two reviewers. The results were synthesised into tables, using narrative synthesis. Results Of the original 3,126 articles, and 16 hand searched citations, 24 studies were included for analysis. Women’s correct general awareness and knowledge of the legal status was less than 50% in nine studies. In six studies, knowledge of legalization/liberalisation ranged between 32.3% - 68.2%. Correct knowledge of abortion on the grounds of rape ranged from 12.8% – 98%, while in the case of incest, ranged from 9.8% - 64.5%. Abortion on the grounds of fetal impairment and gestational limits, varied widely from 7% - 94% and 0% - 89.5% respectively. Conclusion This systematic review synthesizes literature on women’s awareness and knowledge of the abortion law in their own context. The findings show that correct general awareness and knowledge of the abortion law and legal grounds and restrictions amongst women was limited, even in countries where the laws were liberal. Thus, interventions to disseminate accurate information on the legal context are necessary. PMID:27010629

  11. Abortion: rights or technicalities? A comparison of Roe v. Wade with the abortion decision of the German Federal Constitutional Court.

    A comparison of the difference in approach, philosophy, and percepti on of social implications of abortion in the United States and Germany is examined by contrasting the Roe v. Wade decision of the U.S. Supreme Court with the abortion decision of the German Federal Constitutional Court. Roe v. Wade effectively established abortion on demand prior to "viability" (approximately 6 months) and makes it difficult to prevent it for any reason at any time prior to live birth. When the West German Federal Diet passed the Fifth Law for the Reform of the Penal Code which allowed abortion on request up to 12 weeks of conception and for reasons of maternal health up to 22 weeks, the Constitutional Court declared it null and void 8 months later. The 2 courts reached their decisions for quite different reasons. In the U.S. "Jane Roe" was a real, though anonymous, woman. Other real persons had been trying to overturn abortion statutues in various states. The German court acted on a petition brought by 193 members of the Federal Diet and 4 of the states. It was thus, under the German system, obligated to decide the constitutionality of the revisions in abortion legislation and the decision returned the question to the legislative body. The fundamental difference between the German and the American approach is the "right to life." In America the conflict is between the mother's "right to privacy" and the compelling interest of the state to protect the right to life. At no point does the U.S. Supreme Court consider whether the unborn has rights but only whether they constitute a value the protection of which is a legitimate state interest. In Germany, by contrast, the Federal Constitution explicitly establishes the right to life as a subjective human right; the state not only has no right to take life but acknowledges that this right belongs to the human being himself. The U.S. court reasoned that the unborn have been protected "only" for the last century while the German court

    Onscreen pseudo-experiences have been shown to influence public perceptions of contested social issues. However, research has not considered whether such experiences have limits in their influence and/or vary in their impact. Using the case of third-trimester abortion, an issue subject to high amounts of misinformation, low public support and low occurrence in the general population, we investigate how the pseudo-experience of viewing After Tiller, a documentary film showing stories of third-trimester abortion, providers and patients, might serve as a counterpoint to misinformation and myth. We interviewed 49 viewers to assess how viewing the film interacted with viewers' previously held understandings of later abortion. Participants reported that viewing made them feel more knowledgeable about later-abortion patients and providers and increased their support for legal third-trimester abortion access, suggesting the efficacy of this pseudo-experience in changing belief. Nonetheless, respondents' belief systems were not entirely remade and the effects of the film varied, particularly in regards to gatekeeping around the procedure and the reasons why women seek later abortion. Findings show the potential of onscreen pseudo-experiences as a means for social change, but also reveal their limits and varying impacts. PMID:26670628

  14. Abortion funding restrictions on FY 80 DC budget limited to federal portion.

    1979-11-01

    The House of Representatives retreated from its rigid antiabortion stance on the fiscal year 1980 District of Columbia appropriations bill and October 16th accepted an amendment that limits the bill's federal funds for abortions but does not impose any prohibition upon city-raised revenues. The Senate went along with the House "compromise" which limits use of the federal portion of the District's budget (about 15%) to abortion funding only in instances of life endangerment, rape or incest. Resolution of the abortion dispute enabled passage of the city's $1.4 billion budget. Until now, the District of Columbia paid for all medically necessary abortions for poor women. The funds used were locally raised revenue and that part of the city budget which came in the form of a federal payment. The new amendment, in effect, places the District in a situation similar to the 50 states -- the city may opt to fund abortions with state revenues in cases where the federal government refuses to pay. It is likely that the District will continue its liberal funding policy, but it is now required to institute a new accounting system to ensure that only city-raised revenues are being used for expenses relating to abortion.

    Occasionally it is possible to bring together experiment, theory, and simulation in detail. Such an occasion occurred during a high intensity beam physics study in the Spallation Neutron Source (SNS). A transverse dipole instability in the vertical direction has been observed in the accumulator ring for a coasting beam that was stored for 10000 turns. This instability was observed at a beam intensity of about 12 microcoulombs and was characterized by a frequency spectrum peaking at about 6 MHz. The probable cause of the instability is the impedance of the ring extraction kickers. We carry out here a detailed benchmark of the observed instability, uniting an analysis of the experimental data, a precise ORBIT Code tracking simulation, and a theoretical estimate of the observed beam instability.

    Using data from 1,494 Greeks and 1,993 Americans, this study finds that social abortion attitudes are a separate dimension from physical abortion attitudes. According to our structural equation model, abortion attitudes are influenced significantly by religiosity and sexual liberalism. The model explains social abortion attitudes significantly better than physical abortion attitudes. Although the model is applicable to both countries, there are three major differences between Greece and the United States. First, in Greece religiosity has a smaller impact on sexual liberalism, and sexual liberalism has a much weaker impact on both types of abortion attitudes, particularly social abortion attitudes. Second, in Greece religiosity is more strongly related to abortion attitudes than in the United States, particularly to social abortion attitudes. Third, education has a weaker influence in Greece than in the United States.

    Abortion is a relatively frequent experience, yet public discourse about abortion is contentious and stigmatizing. Little literature is available on private conversations about abortion, which may be distinct from public discourse. We explored private discourse by documenting the nature of women's discussions about abortion with peers in a book club. We recruited thirteen women's book clubs in nine states. Participants (n = 119) read the book Choice: True Stories of Birth, Contraception, Infertility, Adoption, Single Parenthood, & Abortion, and participated in a book club meeting, which we audio-recorded and transcribed. Data collection occurred between April 2012 and April 2013. In contrast to public discourse of abortion, private discourse was nuanced and included disclosures of multiple kinds of experiences with abortion. Participants disclosed having abortions, considering abortion as an option for past or future pregnancies, and supporting others through an abortion. Distinguishing between public and private discourse enabled us to identify that an "abortion experience" could include personal decisions, hypothetical decisions, or connection with someone having an abortion. The book club atmosphere provided a rare opportunity for participants to explore their relationship to abortion. More research is needed to understand the role of private discourse in reducing abortion stigma. PMID:26086582

    A review of the progress and problems of the state of Maryland on health care reform is provided. The Standard Benefits Package Task Force completed and approved in a preliminary 7 to 2 vote a long list of benefits, including abortion services, to be covered in health plans that must be made available to small businesses by July 1, 1994. Small businesses are those employing at least 2 workers and no more than 50 workers. The value of benefits cannot exceed $3519, or policies, $3034. The new health care law passed in summer, 1993 stipulated that the value of basic policies for small companies cannot exceed 12% of wages. The development of a minimum package of benefits was the first phase of the health care reform law. Final decision on benefits will be made sometime in the first week of November and presented to the full 7-member Health Care Access and Cost Commission by November 4, 1993. Abortion opponents have opposed insurance coverage of abortions on the grounds that it is not health care and it forces employers opposed to abortion to accept this package, or deny coverage to employees. A public hearing is expected to hear from abortion foes about their notion to offer abortion coverage as an option or "rider" to the standard insurance policy. The task force has another option: to describe the benefit in terms that do not mention abortion per se, but refer to "family planning services and services for pregnant women," which is the wording in the Clinton health care plan. The Director of Public Affairs for Planned Parenthood of Maryland, Bebe Verdery, reported that the organization is strongly opposed to abortion as optional coverage. Kevin Appleby, Associate Director of Social Concerns for the Maryland Catholic Conference, finds that respect for rights of those with moral concerns against abortion should be respected. The task force is confronted with issues of cost, since its initial benefits package was too high, and, most troubling, the controversy over

    For a long time in human history, global population growth was checked by infant mortality, which ranged from 30-50% and did not start sinking until the beginning of the 1800s in the west. Child murder in the west was prohibited by law around the 1100-1200s, but it continued secretly. Among private people, induced abortion was allowed. In the holy scripts of Hinduism and Brahminism, abortion was prohibited. Hippocrates wrote that doctors should not give women abortifacient. The church father Augustinus stated that it was not within human power to discern when the soul entered the body, a circumstance that forbid abortion. A church meeting in 305 A.D. distanced itself from abortion, and this has been the stand of the Catholic Church ever since. In Sweden, exposing a child to the elements was practiced until the end of the 1200s, when it became prohibited. Protestants punished child murder by death. During 1759-78, 217 women were executed for child-killing. From the 1400s, church law punished abortion, and later, capital and punishment was meted out for it, but a distinction was made if the fetus was alive or stillborn. The law in 1734 punished abortion by the death of all concerned. The death penalty was abolished in 1864. In 1896, Anna Linholm reported to the policy in Uppsala that a midwife had been practicing clandestine abortions. Some of her patients were admitted to hospital for hemorrhaging. She was sentenced to hard labor. During 1851-1903, a total of 1408 abortions were reported to the health service. 90% of these became known because of death caused by obduction. Phosphorus was used for abortion in 1271 cases, arsenic in 62, and mechanical aids in 8 cases. About 1//2 of all female suicides at the end of the 1800s was performed by pregnant women who ate phosphorus. Almost all were unmarried, and 56% carried it out after the 5th month of pregnancy. In 1901, phosphorus was prohibited in Swedish homes. In 1875, free abortions became available. However, the

    The central issue in the abortion debate is the moral status of the conceptus. There are two positions that argue this issue. At one extreme are the views of the pro-life group which argues that human life begins at the moment of conception whilst at the other are views of the pro-choice group that argues in favour of a woman's right to self-determination. Two basic principles come into conflict in this debate, namely the Value of Life and that of Self-determination. In this paper the arguments forwarded by each group in justification of its position are presented. Also discussed is the moderate developmental viewpoint which accepts that the genetic basis of an individual is established at conception. Some development, however, has to occur before the conceptus can be called a person. The fact that an entity is a potential person is a prima facie reason for not destroying it. On the other hand, we need not conclude that a person has a right to life by virtue of that potentiality. Simultaneously we should recognise that the right a potential entity has, may be nullified by the woman's right to self-determination. PMID:11993259

    In 2002 Nepal's parliament passed a liberal abortion law, after nearly three decades of reform efforts. This paper reviews the history of the movement for reform and the combination of factors that contributed to its success. These include sustained advocacy for reform; the dissemination of knowledge, information and evidence; adoption of the reform agenda by the public sector and its leadership in involving other stakeholders; the existence of work for safe motherhood as the context in which the initiative could gain support; an active women's rights movement and support from international and multilateral organisations; sustained involvement of local NGOs, civil society and professional organisations; the involvement of journalists and the media; the absence of significant opposition; courageous government officials and an enabling democratic political system. The overriding rationale for reforming the abortion law in Nepal has been to ensure safe motherhood and women's rights. The first government abortion services officially began in March 2004 at the Maternity Hospital in Kathmandu; services will be expanded gradually to other public and private hospitals and private clinics in the coming years.

    This article gives a review of the main factors that are related to the low abortion rate in the Netherlands. Attention is payed to figures on abortion and the use of contraceptive methods since the beginning of the 1960s up to the end of the 1980s. The strong acceptance of family planning was influenced by changing values regarding sexuality and the family, the transition from an agricultural to a modern industrial society, rapid economic growth, declining influence of the churches on daily life, introduction of modern mass media and the increased general educational level. The introduction of modern contraceptives (mainly the pill and contraceptive sterilization) was stimulated by a strong voluntary family planning movement, fear for overpopulation, a positive role of GPs, and the public health insurance system. A reduction of unwanted pregnancies has been accomplished through successful strategies for the prevention of teenage pregnancy (including sex education, open discussions on sexuality in mass media, educational campaigns and low barrier services) as well as through wide acceptance of sterilization. The Dutch experience with family planning shows the following characteristics: a strong wish to reduce reliance on abortion, ongoing sexual and contraceptive education related to the actual experiences of the target groups, and low barrier family planning services.

    Background Abortion is a serious public health issue, and it poses high risks to the health and life of women. Yet safe abortion services are not readily available because few doctors are trained to provide such services. Many doctors are unaware of laws pertaining to abortion. This article reports survey findings on Malaysian medical students’ attitudes toward abortion education and presents a case for including abortion education in medical schools. Methods and Results A survey on knowledge of and attitudes toward abortion among medical students was conducted in two public universities and a private university in Malaysia in 2011. A total of 1,060 students returned the completed questionnaires. The survey covered about 90% of medical students in Years 1, 3, and 5 in the three universities. About 90% of the students wanted more training on the general knowledge and legal aspects of abortion, and pre-and post-abortion counseling. Overall, 75.9% and 81.0% of the students were in favor of including in medical education the training on surgical abortion techniques and medical abortion, respectively. Only 2.4% and 1.7% were opposed to the inclusion of training of these two methods in the curriculum. The remaining respondents were neutral in their stand. Desire for more abortion education was associated with students’ pro-choice index, their intention to provide abortion services in future practice, and year of study. However, students’ attitudes toward abortion were not significantly associated with gender, type of university, or ethnicity. Conclusions Most students wanted more training on abortion. Some students also expressed their intention to provide abortion counseling and services in their future practice. Their desire for more training on abortion should be taken into account in the new curriculum. Abortion education is an important step towards making available safe abortion services to enable women to exercise their reproductive rights. PMID:23300600

    PubMed

    Baron, C H

    1989-01-01

    The Webster decision has not satisfied either side of the abortion debate. The pro-choice groups view this decision as indicating a change in the Court's position on abortion. The decision renders Roe's trimester system invalid and creates more room of abortion regulation at the state level. It will change the battle ground from the federal to the state level. The pro-life groups view it as not being restrictive enough. The state's interest in the fetus has been strengthened, but it is not yet as strong as they would like it to be. Most Americans are neither strongly pro-choice or strongly pro-life, they believe that abortion is a very serious matter that deserves careful consideration of the maternal and fetal rights. Looking to France's abortion legislation reveals the fact that compromise is probably the best solution. In 1975 they adopted a law that recognizes both maternal and fetal rights and value. The law allows for abortion up to week 10, but requires proper respect be paid to the fetus. After week 10 the law becomes more restrictive. Also the law encourages the use of contraceptives in order to avoid unwanted pregnancies, and thus abortions. This law satisfies no one, but keeps everyone happy enough that abortion is no longer apolitical issue. In the US, the Roe decision stated that the fetus had no rights or value in the beginning. It also implied that thinking that life begins at conception was wrong. This is not an example of compromise. The Roe decision only enraged the pro-life groups because they felt that the Court had invalidated their position. If however, the Court had admitted that their position had merit, but that there were other, conflicting positions that also had merit and that a compromise was in order, the abortion controversy would not be one of the biggest political issues to date. Some states will have very restrictive laws, other will continue to have liberal access to abortion.

  7. Latin American women’s experiences with medical abortion in settings where abortion is legally restricted

    PubMed Central

    2012-01-01

    Abortion is legally restricted in most of Latin America where 95% of the 4.4 million abortions performed annually are unsafe. Medical abortion (MA) refers to the use of a drug or a combination of drugs to terminate pregnancy. Mifepristone followed by misoprostol is the most effective and recommended regime. In settings where mifepristone is not available, misoprostol alone is used. Medical abortion has radically changed abortion practices worldwide, and particularly in legally restricted contexts. In Latin America women have been using misoprostol for self-induced home abortions for over two decades. This article summarizes the findings of a literature review on women’s experiences with medical abortion in Latin American countries where voluntary abortion is illegal. Women’s personal experiences with medical abortion are diverse and vary according to context, age, reproductive history, social and educational level, knowledge about medical abortion, and the physical, emotional, and social circumstances linked to the pregnancy. But most importantly, experiences are determined by whether or not women have the chance to access: 1) a medically supervised abortion in a clandestine clinic or 2) complete and accurate information on medical abortion. Other key factors are access to economic resources and emotional support. Women value the safety and effectiveness of MA as well as the privacy that it allows and the possibility of having their partner, a friend or a person of their choice nearby during the process. Women perceive MA as less painful, easier, safer, more practical, less expensive, more natural and less traumatic than other abortion methods. The fact that it is self-induced and that it avoids surgery are also pointed out as advantages. Main disadvantages identified by women are that MA is painful and takes time to complete. Other negatively evaluated aspects have to do with side effects, prolonged bleeding, the possibility that it might not be effective, and

    Abortion decisions have a potentially meaningful effect on the lives of men. Previous research suggests that both men and women generally believe that men have the right to be involved in such decisions. However, very little research attention has been devoted to identifying individual difference correlates of discrepant levels of endorsement for male involvement in abortion decisions. The extent to which abortion attitudes (on a pro-choice to pro-life continuum), conceptualization of abortion as strictly a female issue, and interest in the issue operate as effective predictors of the appropriate level of male involvement in abortion decisions was examined in a sample of 1,387 college students. Results of a multiple regression analysis revealed that 44% of the variance in male involvement scores was explained by the predictor variables. PMID:9919847

    Abortion is a universal phenomenon, occurring throughout recorded history and at all levels of societal organization. Techniques are highly varied, as are the circumstances under which it is practised. The status of and attitudes towards abortion in Western civilization are variable and have, in most cases, been changing. As of 1982, 10% and 18% of the world's population respectively, lived in countries where abortion was totally prohibited or where it was permitted only to save the mother's life. In the USA, various national surveys indicate liberalization of public attitudes towards pregnancy termination between 1965 and the years immediately following the Roe v. Wade Supreme Court decision (1973) which legalized abortion. More recent polls demonstrate little attitudinal change since 1972-1973: between 80% and 90% of Americans approve of abortion in the case of poor health, a seriously defective fetus, or rape, and between 40% and 50% indicate approval for all other reasons as well. Only 10% of the American population would like to see abortion prohibited under all circumstances. Sociodemographic analyses indicate that individuals who disapprove of abortion differ from those who approve of its availability in that they are more likely to be Roman Catholic or fundamentalist Protestant; are, in general, more strongly committed to organized religion; are on the traditional/conservative end of the spectrum with regard to women's role in life, premarital sex, sex education and civil liberties; and tend to have achieved a relatively low educational level. 'Pro-life' and 'pro-choice' activists tend to be women who are completely different from one another in sociodemographic characteristics and in overall values, particularly as these relate to traditional versus modern female roles.

    We studied the effect of previous induced and spontaneous abortion on gestational duration in subsequent pregnancies in 12 obstetric departments in the Netherlands. Only primiparae were studied. Of 504 women who had had a previous induced abortion, 18 (3.6%) delivered before 32 weeks' gestational age. Forty of 1313 women with a history of spontaneous abortion (3.0%) and 259 of 12 678 women with no history of abortion (2.1%) also delivered before 32 weeks. The differences between the three groups were not significant. In the Netherlands there are no significant indications that spontaneous midtrimester abortions or premature deliveries are caused by a previous induced abortion. PMID:620303

    Access to abortion remains a controversial issue worldwide. In Ireland, both north and south, legal restrictions have resulted in thousands of women travelling to England and Wales and further afield to obtain abortions in the last decade alone, while others purchase the 'abortion pill' from Internet sources. This paper considers the socio-legal context in both jurisdictions, the data on those travelling to access abortion and the barriers to legal reform. It argues that moral conservatism in Ireland, north and south, has contributed to the restricted access to abortion, impacting on the experience of thousands of women, resulting in these individuals becoming 'abortion tourists'.

    OBJECTIVE: To describe women's experiences with expectant management of spontaneous abortions. DESIGN: Descriptive survey using questionnaires with fixed-choice and open-ended questions. The latter were analyzed for themes, using qualitative methods. SETTING: Urban and suburban private primary care family practices. PARTICIPANTS: A convenience sample of family practice patients (59 of 80 eligible) pregnant for less than 12 weeks who had spontaneous abortions without surgery. Response rate was 84.7%; 50 questionnaires were received from the 59 women. METHOD: Women were asked about their physical experiences, including amount of pain and bleeding; emotional effects; their satisfaction with medical care; and their suggestions for improving care. MAIN FINDINGS: The mean worst pain experienced during a spontaneous abortion on an 11-point scale was 5.9. Bleeding varied, but was often very heavy. Satisfaction rate was 92.9% with family physician care and 84.6% with hospital care. Women described the emotional effect of "natural" spontaneous abortions and made recommendations for improving care. CONCLUSIONS: A better understanding of the physical and emotional experiences of the women in this study might help physicians better prepare and support patients coping with expectant management of spontaneous abortions.

    The number of pregnancies and induced abortions among Japanese teenagers has recently increased. 2 of 5 pregnant single women whom social workers assist are teenagers. The teenagers fall into 2 groups: those under 18, who are in a sexually awakening period, or 18 and older, who are maturing. Those under 18, despite a strong tendency toward sexual activity, are predominantly insecure and run away from home to escape adversity and seek friendship among members of the opposite sex. After becoming pregnant, they go home only to embarrass their parents. Ultimately, they choose abortion or, because of their own inability, their babies are taken care of by their families or in foster homes. Those 18 or older, despite their knowledge of the relationship between sexual intercourse and pregnancy, typically did not take it seriously. Consequently, their reaction to their pregnancies tends toward shock and panic. Many try to keep their pregnancy from their parents. Though they do not want abortion, their circumstances may force them to it. Behind the increase of unexpected pregnancy and unwanted abortion in both age groups are several factors: the lack of sexual education suitable to their level of their physical maturity; a lack of responsibility by the male teenagers, who cannot relate their own actions to their partners' pregnancies; and the ignorance of pregnant teenagers, who cannot see that abortions may hurt them not only physically but mentally in the long run.

    While the issue of abortion has fueled a great deal of personal and political debate and controversy in the US, few have actually read the Supreme Court's rulings on Roe v. Wade and Planned Parenthood of Southeastern Pennsylvania v. Casey, which are central to the debate. This essay summarizes both rulings, examines the difference between the 2, and discusses implications for medical practice. Casey is important to states, physicians, and patients. Of central import is the ruling's restriction against states to outlaw abortion before viability. Other measures are, however, included which will complicate record keeping and securing consent. Restrictions against and/or steps required by the physician practicing abortion may also spread to apply to other medical procedures. The essay considers the future of Roe v. Wade. Whether or not a Freedom of Choice Act is ultimately passed in Congress, abortion will continue to divide large segments of the American population. Anti-abortionists will continue to attempt to overthrow women's right of free choice to abortion.

  15. Access to abortion services: abortions performed by mid-level practitioners.

    Because the number of physicians available to perform abortions in the US is dwindling, certified nurse-midwives, nurse practitioners, and physician assistants should be trained and permitted to perform abortions. Roadblocks to this change are the fact that the Supreme Court would likely allow states to prevent mid-level practitioners from performing abortions in the name of protecting the health of the mother. Also, existing statutes would probably not be interpreted by courts to allow mid-level practitioners to perform abortions. However, physician assistants have been performing abortions in Vermont since 1975, and a 1981-82 comparative study affirmed that physician assistants are well-equipped to perform abortions (of 2458 procedures, the complication rate/1000 was 27.4 for physician assistants and 30.8 for physicians). However, controversy surrounds the provision of abortion by these physician assistants in Vermont, since the relevant statute suggests that abortion is illegal unless performed by a physician. However, the statute has not been changed since Roe vs. Wade and is likely unconstitutional. Court cases in Missouri and Tennessee suggest that courts may be willing to include abortion within the scope of progressive nursing practice acts, but a recent similar case in Massachusetts resulted in a narrow interpretation of nursing practice statutes. Because the definition of professional nursing varies with each state statute, it will be a formidable task to convince every jurisdiction to include abortion as a permissible mid-level practice. Even in Vermont, the nursing practice statute defines in an exclusive list what services the professional nurse may perform (whereas the physician assistant regulations limit their scope of practice only to that delegated by a supervising physician). States could, of course, pass statutes which include abortion as a permissible practice for the mid-level practitioner. However, specific legislation would provide a clear

    Bovine abortion surveillance is essential for human and animal health because it plays an important role in the early warning of several diseases. Due to the limited sensitivity of traditional surveillance systems, there is a growing interest for the development of syndromic surveillance. Our objective was to assess whether, routinely collected, artificial insemination (AI) data could be used, as part of a syndromic surveillance system, to devise an indicator of mid-term abortions in dairy cattle herds in France. A mid-term abortion incidence rate (MAIR) was computed as the ratio of the number of mid-term abortions to the number of female-weeks at risk. A mid-term abortion was defined as a return-to-service (i.e., a new AI) taking place 90 to 180 days after the previous AI. Weekly variations in the MAIR in heifers and parous cows were modeled with a time-dependent Poisson model at the département level (French administrative division) during the period of 2004 to 2010. The usefulness of monitoring this indicator to detect a disease-related increase in mid-term abortions was evaluated using data from the 2007-2008 episode of bluetongue serotype 8 (BT8) in France. An increase in the MAIR was identified in heifers and parous cows in 47% (n = 24) and 71% (n = 39) of the departements. On average, the weekly MAIR among heifers increased by 3.8% (min-max: 0.02-57.9%) when the mean number of BT8 cases that occurred in the previous 8 to 13 weeks increased by one. The weekly MAIR among parous cows increased by 1.4% (0.01-8.5%) when the mean number of BT8 cases occurring in the previous 6 to 12 weeks increased by one. These results underline the potential of the MAIR to identify an increase in mid-term abortions and suggest that it is a good candidate for the implementation of a syndromic surveillance system for bovine abortions.

    This paper discusses the implementation of abort gap beam intensity monitoring at the Tevatron collider at Fermilab. There are two somewhat independent monitors which measure the intensity of the synchrotron light emitted by particles in the abort gaps. One system uses a gated Photomultiplier Tube (PMT) to measure the light intensity, and the other system uses a single lens telescope, gated image intensifier, and Charge Injection Device (CID) camera to image the beam.
