    The purpose of this study was to explore the role of emotional intelligence (EI) in medical laboratory science, as perceived by laboratory administrators. To collect and evaluate these perceptions, a survey was developed and distributed to over 1,400 medical laboratory administrators throughout the U.S. during January and February of 2013. In addition to demographic-based questions, the survey contained a list of 16 items, three skills traditionally considered important for successful work in the medical laboratory as well as 13 EI-related items. Laboratory administrators were asked to rate each item for its importance for job performance, their satisfaction with the item's demonstration among currently working medical laboratory scientists (MLS) and the amount of responsibility college-based medical laboratory science programs should assume for the development of each skill or attribute. Participants were also asked about EI training in their laboratories and were given the opportunity to express any thoughts or opinions about EI as it related to medical laboratory science. This study revealed that each EI item, as well as each of the three other items, was considered to be very or extremely important for successful job performance. Administrators conveyed that they were satisfied overall, but indicated room for improvement in all areas, especially those related to EI. Those surveyed emphasized that medical laboratory science programs should continue to carry the bulk of the responsibility for the development of technical skills and theoretical knowledge and expressed support for increased attention to EI concepts at the individual, laboratory, and program levels.

    Leibach, Elizabeth Kenimer

    2011-01-01

    Grounded theory and methods related to expert practice development in medical laboratory science were described using data from a large national survey of medical laboratory scientists (MLS) overlaid on findings from analysis of expert practice domains reported in nursing literature. An extensive focus group/expert review iterative process followed by a survey of MLS practitioners produced 25 critical thinking (CT) behaviors important in expert practice. Factor analysis was applied to discern common threads or themes linking the CT behaviors. The 25 important CT behaviors were reduced to a 7-factor structure representing constructs underlying the individual, observable CT behaviors. This 7-factor structure in MLS was compared to the 7 practice domains identified in expert nursing practice. The comparison yielded commonality between MLS and nursing in CT behaviors observed in the 7 expert practice domains of both professions: professional techniques, caring communication, growing professionally, setting priorities, practicing with judgment, anticipating/revising, and creating unique meaning. Emergent grounded theory is that (1) critical thinking is a metaprocess that facilitates learning by interlinking the more basic processes associated with different learning orientations: cognitivist, behaviorist, humanist (affective), and situated/contextual learning, (2) CT behaviors are observable events following from the CT metaprocess, and (3) observations of CT behaviors increase as practice advances from novice to expert. Identification and definition of CT behaviors, i.e., practice competencies, along the continuum of novice to expert can serve as the foundation for MLS curriculum and instructional design as well as measurement and evaluation in both formal and continuing education settings.

  5. Developing a theory of clinical instructor identity using the experiences of medical laboratory science practitioners.

    PubMed

    Miller, Wendy

    2014-01-01

    This study investigated medical laboratory science clinical instructors' beliefs about teaching and how they viewed themselves as teachers. The first phase of the study included an integrative literature review, which suggested that the development of teacher identity in school-based educators, and to a lesser extent higher education faculty, is dependent on four dimensions: personal factors, training factors, contextual factors, and reflective practice. The second phase of this study began qualitative inquiry into the ways that these participants described their teaching and professional identity. Interviews were conducted with medical laboratory science clinical instructors in order to gain an understanding of their perceptions of themselves as teachers. The data collected in this study indicate that this group of clinical instructors saw themselves as teachers who were responsible for providing students with technical skills needed to become competent practitioners and the theoretical foundation necessary to pass the national certification exam. The study participants also saw themselves as mentors who were responsible for passing along professional knowledge to the next generation of laboratory practitioners. During data analysis three themes emerged that represent aspects of teacher identity in clinical instructors: belief in one's teaching ability, desire to expand one's professional responsibilities, and reflection on one's teaching. The findings from this study may provide a foundation for future research designed to measure teacher identity in clinical instructors. PMID:25000652

    Background: The number of malaria cases is declining worldwide; however, it remains as a serious health problem. Diagnosing unusual cases is the most important issue to manage the problem. This study designed to describe the number of falciparum and vivax malaria infected patients referred to Malaria Reference Laboratory in Tehran University of Medical Science from 2000 to 2012. Methods: A retrospective study was conducted based on the collected questionnaires from each patient referred to the laboratory. Diagnosing results and demographic information for positive cases were analyzed using SPSS software. Problematic cases were evaluated for any difficulties in diagnosis or in clinical signs. Scanning and molecular methods were performed whenever there was an atypical case referred to the laboratory. Some of the samples had various difficulties for diagnosing such as presence of fussed gametocytes and schizonts of Plasmodium falciparum in peripheral blood and CCHF like hemoragic disorders. Results: Plasmodium vivax caused a large proportion of the cases (76.1%) in contrast with P. falciparum that included smaller proportion (22.8%) and the rest (1.1) belonged to mixed infection. Most of the positive cases (69.6%) were belonged to Afghani people. Men (94.6%) showed more infection than women (5.4%), moreover the most infection (44.5%) was seen at a range of 21–30 yr. Conclusion: In the case of existing atypical issues to diagnose, it is needed to perform more precise microscopical examination beyond the current standard conditions. Sometimes molecular method is required to verify the exact agent of the disease. PMID:26811720

  8. Using performance tasks employing IOM patient safety competencies to introduce quality improvement processes in medical laboratory science education.

    PubMed

    Golemboski, Karen; Otto, Catherine N; Morris, Susan

    2013-01-01

    In order to contribute to improved healthcare quality through patient-centered care, laboratory professionals at all levels of practice must be able to recognize the connection between non-analytical factors and laboratory analysis, in the context of patient outcomes and quality improvement. These practices require qualities such as critical thinking (CT), teamwork skills, and familiarity with the quality improvement process, which will be essential for the development of evidence-based laboratory science practice. Performance tasks (PT) are an educational strategy which can be used to teach and assess CT and teamwork, while introducing Medical Laboratory Science (MLS) students at both baccalaureate and advanced-practice levels to the concepts of quality improvement processes and patient outcomes research. PT presents students with complex, realistic scenarios which require the incorporation of subject-specific knowledge with competencies such as effective team communication, patient-centered care, and successful use of information technology. A PT with assessment rubric was designed for use in a baccalaureate-level MLS program to teach and assess CT and teamwork competency. The results indicated that, even when students were able to integrate subject-specific knowledge in creative ways, their understanding of teamwork and quality improvement was limited. This indicates the need to intentionally teach skills such as collaboration and quality system design. PT represent one of many strategies that may be used in MLS education to develop essential professional competencies, encourage expert practice, and facilitate quality improvement. PMID:24432515

    This International Standard, based upon ISO/IEC 17025 and ISO 9001, provides requirements for competence and quality that are particular to medical laboratories. While this International Standard is intended for use throughout the currently recognized disciplines of medical laboratory services, those working in other services and disciplines will also find it useful and appropriate. In addition, bodies engaged in the recognition of the competence of medical laboratories will be able to use this International Standard as the basis for their activities. The Japan Accreditation Board for Conformity Assessment (AB) and the Japanese Committee for Clinical Laboratory Standards (CCLS) are jointly developing the program of accreditation of medical laboratories. ISO 15189 requirements consist of two parts, one is management requirements and the other is technical requirements. The former includes the requirements of all parts of ISO 9001, moreover it includes the requirement of conformity assessment body, for example, impartiality and independence from any other party. The latter includes the requirements of laboratory competence (e.g. personnel, facility, instrument, and examination methods), moreover it requires that laboratories shall participate proficiency testing(s) and laboratories' examination results shall have traceability of measurements and implement uncertainty of measurement. Implementation of ISO 15189 will result in a significant improvement in medical laboratories management system and their technical competence. The accreditation of medical laboratory will improve medical laboratory service and be useful for patients. PMID:15624503

    During the 20th century understanding for quality has changed and international and national requirements for quality have been published. Therefore also medical branches started to establish quality management systems. Quality assurance has always been important for medical laboratories. Certification according to the standard ISO 9001 and accreditation according to the standard ISO 17025 have been the proof of fulfilling quality requirements. The relatively new standard ISO 15189 is the first standard for medical laboratories. This standard includes technical and management requirements for the medical laboratory. The main focus is the proof of competence within the personnel. As this standard is accepted throughout the European Union an increase in accreditations of medical laboratories is predictable.

    2010-01-01

    The Drill for the Mars Science Laboratory mission is a rotary-percussive sample acquisition device with an emphasis on toughness and robustness to handle the harsh environment on Mars. The unique challenges associated with autonomous drilling from a mobile robot are addressed. A highly compressed development schedule dictated a modular design architecture that satisfies the functional and load requirements while allowing independent development and testing of the Drill subassemblies. The Drill consists of four actuated mechanisms: a spindle that rotates the bit, a chuck that releases and engages bits, a novel voice-coil-based percussion mechanism that hammers the bit, and a linear translation mechanism. The Drill has three passive mechanisms: a replaceable bit assembly that acquires and collects sample, a contact sensor / stabilizer mechanism, and, lastly a flex harness service loop. This paper describes the various mechanisms that makeup the Drill and discusses the solutions to their unique design and development challenges.

    2014-12-01

    The relevance of basic sciences in medical education has been recognized for centuries, and the importance of exposing medical students to science was acknowledged and reinforced by the recommendations of Flexner in 1910. Since then, traditional medical education has been divided into preclinical and clinical subjects; within this scheme, the first terms of undergraduate medical education usually concentrate on basic sciences, while subsequent ones focus on clinical sciences and clinical training. Since 1956, this educational scheme has been questioned and, in some schools, the medical curriculum has undergone significant structural changes; some of these reforms, especially integrated curricula, are associated with important reductions in the time allotted to individual basic science courses or even with their removal. The removal of basic science subjects from the medical curriculum is paradoxical because nowadays the value of biomedical knowledge and the scientific reasoning to make medical decisions is more appreciated than ever. To maintain its relevance in medical education, basic sciences have to confront three challenges: a) increasing its presence in clinical education; b) developing nuclear programs; and c) renewing laboratory instruction.

    This drill (see Figure 1) is the primary sample acquisition element of the Mars Science Laboratory (MSL) that collects powdered samples from various types of rock (from clays to massive basalts) at depths up to 50 mm below the surface. A rotary-percussive sample acquisition device was developed with an emphasis on toughness and robustness to handle the harsh environment on Mars. It is the first rover-based sample acquisition device to be flight-qualified (see Figure 2). This drill features an autonomous tool change-out on a mobile robot, and novel voice-coil-based percussion. The drill comprises seven subelements. Starting at the end of the drill, there is a bit assembly that cuts the rock and collects the sample. Supporting the bit is a subassembly comprising a chuck mechanism to engage and release the new and worn bits, respectively, and a spindle mechanism to rotate the bit. Just aft of that is a percussion mechanism, which generates hammer blows to break the rock and create the dynamic environment used to flow the powdered sample. These components are mounted to a translation mechanism, which provides linear motion and senses weight-on-bit with a force sensor. There is a passive-contact sensor/stabilizer mechanism that secures the drill fs position on the rock surface, and flex harness management hardware to provide the power and signals to the translating components. The drill housing serves as the primary structure of the turret, to which the additional tools and instruments are attached. The drill bit assembly (DBA) is a passive device that is rotated and hammered in order to cut rock (i.e. science targets) and collect the cuttings (powder) in a sample chamber until ready for transfer to the CHIMRA (Collection and Handling for Interior Martian Rock Analysis). The DBA consists of a 5/8-in. (.1.6- cm) commercial hammer drill bit whose shank has been turned down and machined with deep flutes designed for aggressive cutting removal.

    Life Sciences Research at LBL has both a long history and a new visibility. The physics technologies pioneered in the days of Ernest O. Lawrence found almost immediate application in the medical research conducted by Ernest's brother, John Lawrence. And the tradition of nuclear medicine continues today, largely uninterrupted for more than 50 years. Until recently, though, life sciences research has been a secondary force at the Lawrence Berkeley Laboratory (LBL). Today, a true multi-program laboratory has emerged, in which the life sciences participate as a full partner. The LBL Human Genome Center is a contribution to the growing international effort to map the human genome. Its achievements represent LBL divisions, including Engineering, Materials and Chemical Sciences, and Information and Computing Sciences, along with Cell and Molecular Biology and Chemical Biodynamics. The Advanced Light Source Life Sciences Center will comprise not only beamlines and experimental end stations, but also supporting laboratories and office space for scientists from across the US. This effort reflects a confluence of scientific disciplines --- this time represented by individuals from the life sciences divisions and by engineers and physicists associated with the Advanced Light Source project. And finally, this report itself, the first summarizing the efforts of all four life sciences divisions, suggests a new spirit of cooperation. 30 figs.

    This image from July 2008 shows the aeroshell for NASA's Mars Science Laboratory while it was being worked on by spacecraft technicians at Lockheed Martin Space Systems Company near Denver.

    This hardware was delivered in early fall of 2008 to NASA's Jet Propulsion Laboratory, Pasadena, Calif., where the Mars Science Laboratory spacecraft is being assembled and tested.

    The aeroshell encapsulates the mission's rover and descent stage during the journey from Earth to Mars and shields them from the intense heat of friction with that upper atmosphere during the initial portion of descent.

    The aeroshell has two main parts: the backshell, which is on top in this image and during the descent, and the heat shield, on the bottom. The heat shield in this image is an engineering unit for testing. The heat shield to be used in flight will be substituted later. The heat shield has a diameter of about 15 feet. For comparison, the heat shields for NASA's Mars Exploraton Rovers Spirit and Opportunity were 8.5 feet and the heat shields for the Apollo capsules that protected astronauts returning to Earth from the moon were just under 13 feet.

    In addition to protecting the Mars Science Laboratory rover, the backshell provides structural support for the descent stage's parachute and sky crane, a system that will lower the rover to a soft landing on the surface of Mars. The backshell for the Mars Science Laboratory is made of an aluminum honeycomb structure sandwiched between graphite-epoxy face sheets. It is covered with a thermal protection system composed of a cork/silicone super light ablator material that originated with the Viking landers of the 1970s. This ablator material has been used on the heat shields of all NASA Mars landers in the past, but this mission is the first Mars mission using it on the backshell.

    Social Values, no less than medical science, have shaped the medical management of the pain of childbirth. Nineteenth century feminists fought for greater use of anesthesia in obstetrics at a time when physicians held back for fear of its effects on labor, hemorrhage, rates of infection and the condition of the child. A century later, after physicians became comfortable with the use of anesthesia, a new generation of feminists challenged the use of such drugs, once again citing social considerations. The personalities of colorful and charismatic obstetricians such as James Young Simpson and Grantley Dick-Read played a strong part in the outcome of each confrontation. PMID:15321396

    Space Shuttle and Spacelab missions will provide scientists with their first opportunity to participate directly in research in space for all scientific disciplines, particularly the Life Sciences. Preparations are already underway to ensure the success of these missions. The paper summarizes the results of the 1975 NASA-funded Life Sciences Laboratories definition study which defined several long-range life sciences research options and the laboratory designs necessary to accomplish high-priority life sciences research. The implications and impacts of Spacelab design and development on the life sciences missions are discussed. An approach is presented based upon the development of a general-purposs laboratory capability and an inventory of common operational research equipment for conducting life sciences research. Several life sciences laboratories and their capabilities are described to demonstrate the systems potentially available to the experimenter for conducting biological and medical research.

    This paper describes the orbit determination process, results and filter strategies used by the Mars Science Laboratory Navigation Team during cruise from Earth to Mars. The new atmospheric entry guidance system resulted in an orbit determination paradigm shift during final approach when compared to previous Mars lander missions. The evolving orbit determination filter strategies during cruise are presented. Furthermore, results of calibration activities of dynamical models are presented. The atmospheric entry interface trajectory knowledge was significantly better than the original requirements, which enabled the very precise landing in Gale Crater.

    Surface science has developed into a multidisciplinary field of research with applications ranging from heterogeneous catalysis to semiconductor etching (1). Aspects of surface chemistry are now included in physical chemistry textbooks (2) and undergraduate curricula (3), but the perceived cost and complexity of equipment has deterred the introduction of surface science methods in undergraduate laboratories (4). Efforts to expose chemistry undergraduates to state-of-the-art surface instrumentation have just begun (5). To provide our undergraduates with hands-on experience in using standard techniques for characterizing surface morphology, adsorbates, kinetics, and reaction mechanisms, we have developed a set of surface science experiments for our physical chemistry laboratory sequence. The centerpiece of the laboratory is an ultrahigh vacuum (UHV) chamber for studies of single crystal surfaces. This instrument, shown in the figure, has surface analysis capabilities including low energy electron diffraction (LEED), Auger spectroscopy, and temperature-programmed desorption (TPD). The laboratory exercises involve experiments on the well-studied Pt(111) surface. Students prepare a previously mounted single crystal sample by sputtering it with an argon ion gun and heating it under O2. Electron diffraction patterns from the cleaned surface are then obtained with a reverse view LEED apparatus (Princeton Instruments). Images are captured by a charge-coupled device (CCD) camera interfaced to a personal computer for easy downloading and subsequent analysis. Although the LEED images from a Pt(111) surface can be readily interpreted using simple diffraction arguments, this lab provides an excellent context for introducing Miller indices and reciprocal lattices (6). The surface chemical composition can be investigated by Auger spectroscopy, using the LEED apparatus as a simple energy analyzer. The temperature programmed desorption experiment, which is nearly complete, will be

    A process for separating chemical compounds in fluids resulted from a Jet Propulsion Laboratory (JPL)/LAPD project. The technique involves pouring a blood or urine sample into an extraction tube where packing material contained in a disposable tube called an "extraction column" absorbs water and spreads the specimen as a thin film, making it easy to identify specific components. When a solvent passes through the packing material, the desired compound dissolves and exits through the tube's bottom stem and is collected. Called AUDRI, Automated Drug Identification, it is commercially produced by Analytichem International which has successfully advanced the original technology.

    Scheduled to land in August of 2012, the Mars Science Laboratory (MSL) Mission was initiated to explore the habitability of Mars. This includes both modern environments as well as ancient environments recorded by the stratigraphic rock record preserved at the Gale crater landing site. The Curiosity rover has a designed lifetime of at least one Mars year (˜23 months), and drive capability of at least 20 km. Curiosity's science payload was specifically assembled to assess habitability and includes a gas chromatograph-mass spectrometer and gas analyzer that will search for organic carbon in rocks, regolith fines, and the atmosphere (SAM instrument); an x-ray diffractometer that will determine mineralogical diversity (CheMin instrument); focusable cameras that can image landscapes and rock/regolith textures in natural color (MAHLI, MARDI, and Mastcam instruments); an alpha-particle x-ray spectrometer for in situ determination of rock and soil chemistry (APXS instrument); a laser-induced breakdown spectrometer to remotely sense the chemical composition of rocks and minerals (ChemCam instrument); an active neutron spectrometer designed to search for water in rocks/regolith (DAN instrument); a weather station to measure modern-day environmental variables (REMS instrument); and a sensor designed for continuous monitoring of background solar and cosmic radiation (RAD instrument). The various payload elements will work together to detect and study potential sampling targets with remote and in situ measurements; to acquire samples of rock, soil, and atmosphere and analyze them in onboard analytical instruments; and to observe the environment around the rover. The 155-km diameter Gale crater was chosen as Curiosity's field site based on several attributes: an interior mountain of ancient flat-lying strata extending almost 5 km above the elevation of the landing site; the lower few hundred meters of the mountain show a progression with relative age from clay-bearing to sulfate

    Medical laboratory testing is vital for investigating and managing children who have environmentally related disorders and children with environmental chemical exposures. Few of these compounds can be measured in a routine clinical service laboratory. An understanding of the exposure circumstances and toxicology of the agent is required for the ordering and interpretation of tests. Test interpretation requires understanding of the capabilities and limitations of these tests. Adequate investigation, management, and follow-up of exposed children are mandatory. PMID:17448366

    2011-01-01

    The Mars Science Laboratory will be the first Mars mission to attempt a guided entry with the objective of safely delivering the entry vehicle to a survivable parachute deploy state within 12.5 km of the pre-designated parachute deploy coordinates. The Entry Terminal Point Controller guidance algorithm is derived from the final phase Apollo Command Module guidance and, like Apollo, modulates the bank angle to control range based on deviations in range, altitude rate, and drag acceleration from a reference trajectory. For application to Mars landers which must make use of the tenuous Martian atmosphere, it is critical to balance the lift of the vehicle to minimize the range while still ensuring a safe deploy altitude. An overview of the process to generate optimized guidance settings is presented, discussing improvements made over the last nine years. Performance tradeoffs between ellipse size and deploy altitude will be presented, along with imposed constraints of entry acceleration and heating. Performance sensitivities to the bank reversal deadbands, heading alignment, attitude initialization error, and entry delivery errors are presented.

    NASA's Mars Science Laboratory (MSL) Rover, which launched to Mars in 2011, is equipped with a set of 12 engineering cameras. These cameras are build-to-print copies of the Mars Exploration Rover (MER) cameras, which were sent to Mars in 2003. The engineering cameras weigh less than 300 grams each and use less than 3 W of power. Images returned from the engineering cameras are used to navigate the rover on the Martian surface, deploy the rover robotic arm, and ingest samples into the rover sample processing system. The navigation cameras (Navcams) are mounted to a pan/tilt mast and have a 45-degree square field of view (FOV) with a pixel scale of 0.82 mrad/pixel. The hazard avoidance cameras (Haz - cams) are body-mounted to the rover chassis in the front and rear of the vehicle and have a 124-degree square FOV with a pixel scale of 2.1 mrad/pixel. All of the cameras utilize a frame-transfer CCD (charge-coupled device) with a 1024x1024 imaging region and red/near IR bandpass filters centered at 650 nm. The MSL engineering cameras are grouped into two sets of six: one set of cameras is connected to rover computer A and the other set is connected to rover computer B. The MSL rover carries 8 Hazcams and 4 Navcams.

  4. Clinical laboratories: production industry or medical services?

    PubMed

    Plebani, Mario

    2015-06-01

    The current failure to evidence any link between laboratory tests, clinical decision-making and patient outcomes, and the scarcity of financial resources affecting healthcare systems worldwide, have put further pressure on the organization and delivery of laboratory services. Consolidation, merger, and laboratory downsizing have been driven by the need to deliver economies of scale and cut costs per test while boosting productivity. Distorted economics, based on payment models rewarding volume and efficiency rather than quality and clinical effectiveness, have underpinned the entrance of clinical laboratories into the production industry thus forcing them to relinquish their original mission of providing medical services. The sea change in laboratory medicine in recent years, with the introduction of ever newer and ever more complex tests, including 'omics', which impact on clinical decision-making, should encourage clinical laboratories to return to their original mission as long as payments models are changed. Rather than being considered solely in terms of costs, diagnostic testing must be seen in the context of an entire hospital stay or an overall payment for a care pathway: the testing process should be conceived as a part of the patient's entire journey.

    In order to reveal impacts of natural and social sciences on each other, the authors examined connections between fields of medical and social sciences using a search for references and citations of scientific publication. 1. The largest affinity between the medical and social sciences was found between neurosciences and psychology, but there was a significant affinity between clinical sciences and general social sciences, as well. 2. The example of General & Internal Medicine papers in the topics of "diabetes" suggests that in the period 2001-2010 the share of references to social sciences was significantly increased. In the meantime, social science papers in the same topics contained references to Clinical Medicine papers in a constantly high percentage. 3. In the sample under study, the age distribution of social science papers in the references did not differ significantly from that of the other sources. 4. Share of references to social science papers was found to be extremely high among Hungarian General & Internal Medicine papers in the topics of "diabetes". This finding still requires clarification, nevertheless, since e.g. it was not supported by an institutional comparison including the largest Hungarian medical research university. 5. The intensity of the reference/citation mediated information flows between the Hungarian Medical Journal, Orvosi Hetilap and social sciences appears to be in accordance with the current international trends.

As exemplified with the complement gene family, containing C2, C3, C8A, C8B, CFH, CFI, and ITGB2, heritability patterns/risk factors associated with diseases with genetic glitch of complement components are unfolding. The C4 component serum levels depend on sufficient vitamin D whilst low vitamin D is inversely related to IgG1, IgA, and C3 linking vitamin sufficiency to innate immunity. Whole genome sequencing of microbial organisms may distinguish virulent from nonvirulent and antibiotic resistant from nonresistant varieties of the same species and thus can be listed in personal big data banks including microbiological pathology; the big data warehouse continues to grow.

    The Mars Science Laboratory (MSL), carrying the Curiosity rover to Mars, was launched on November 26, 2011, from Cape Canaveral, Florida. The target for MSL was selected to be Gale Crater, near the equator of Mars, with an arrival date in early August 2012. The two main interplanetary navigation tasks for the mission were to deliver the spacecraft to an entry interface point that would allow the rover to safely reach the landing area, and to tell the spacecraft where it entered the atmosphere of Mars, so it could guide itself accurately to close proximity of the landing target. MSL used entry guidance as it slowed down from the entry speed to a speed low enough to allow for a successful parachute deployment, and this guidance allowed shrinking the landing ellipse to a 99% conservative estimate of 7 by 20 kilometers. Since there is no global positioning system in Mars, achieving this accuracy was predicated on flying a trajectory that closely matched the reference trajectory used to design the guidance algorithm, and on initializing the guidance system with an accurate Mars-relative entry state that could be used as the starting point to integrate the inertial measurement unit data during entry and descent. The pre-launch entry flight path angle (EFPA) delivery requirement was +/- 0.20 deg, but after launch a smaller threshold of +/- 0.05 deg was used as the criteria for late trajectory correction maneuver (TCM) decisions. The pre-launch requirement for entry state knowledge was 2.8 kilometers in position error and 2 meters per second in velocity error, but also smaller thresholds were defined after launch to evaluate entry state update opportunities. The biggest challenge for the navigation team was to accurately predict the trajectory of the spacecraft, so the estimates of the entry conditions could be stable, and late trajectory correction maneuvers or entry parameter updates could be waved off. As a matter of fact, the prediction accuracy was such that the last

  3. Standardizing and personalizing science in medical education.

    Lambert, David R; Lurie, Stephen J; Lyness, Jeffrey M; Ward, Denham S

    2010-02-01

    In the century since the initial publication of the Flexner Report, medical education has emphasized a broad knowledge of science and a fundamental understanding of the scientific method, which medical educators believe are essential to the practice of medicine. The enormous growth of scientific knowledge that underlies clinical practice has challenged medical schools to accommodate this new information within the curricula. Although innovative educational modalities and new curricula have partly addressed this growth, the authors argue for a systematic restructuring of the content and structure of science education from the premedical setting through clinical practice. The overarching goal of science education is to provide students with a broad, solid foundation applicable to medicine, a deep understanding of the scientific method, and the attitudes and skills needed to apply new knowledge to patient care throughout their careers. The authors believe that to accomplish this successfully, the following changes must occur across the three major stages of medical education: (1) a reshaping of the scientific preparation that all students complete before medical school, (2) an increase in individualized science education during medical school, and (3) an emphasis on knowledge acquisition skills throughout graduate medical education and beyond to assure lifelong scientific learning. As students progress through the educational continuum, the balance of standardized and personalized scientific knowledge will shift toward personalization. Greater personalization demands that physicians possess well-refined skills in information acquisition, interpretation, and application for optimal lifelong learning and effective clinical practice.

    The study determined how students assess the various components of their science laboratory environment. It also identified how the laboratory environment affects students' learning outcomes. The modified ex-post facto design was used. A sample of 328 randomly selected students was taken from a population of all Senior Secondary School chemistry students in a state in Nigeria. The research instrument, Science Laboratory Environment Inventory (SLEI) designed and validated by Fraser et al. (Sci Educ 77:1-24, 1993) was administered on the selected students. Data analysis was done using descriptive statistics and Product Moment Correlation. Findings revealed that students could assess the five components (Student cohesiveness, Open-endedness, Integration, Rule clarity, and Material Environment) of the laboratory environment. Student cohesiveness has the highest assessment while material environment has the least. The results also showed that the five components of the science laboratory environment are positively correlated with students' academic performance. The findings are discussed with a view to improving the quality of the laboratory environment, subsequent academic performance in science and ultimately the enrolment and retaining of learners in science.

  5. Sandia National Laboratories Medical Isotope Reactor concept.

    Coats, Richard Lee; Dahl, James J.; Parma, Edward J., Jr.

    2010-04-01

    This report describes the Sandia National Laboratories Medical Isotope Reactor and hot cell facility concepts. The reactor proposed is designed to be capable of producing 100% of the U.S. demand for the medical isotope {sup 99}Mo. The concept is novel in that the fuel for the reactor and the targets for the {sup 99}Mo production are the same. There is no driver core required. The fuel pins that are in the reactor core are processed on a 7 to 21 day irradiation cycle. The fuel is low enriched uranium oxide enriched to less than 20% {sup 235}U. The fuel pins are approximately 1 cm in diameter and 30 to 40 cm in height, clad with Zircaloy (zirconium alloy). Approximately 90 to 150 fuel pins are arranged in the core in a water pool {approx}30 ft deep. The reactor power level is 1 to 2 MW. The reactor concept is a simple design that is passively safe and maintains negative reactivity coefficients. The total radionuclide inventory in the reactor core is minimized since the fuel/target pins are removed and processed after 7 to 21 days. The fuel fabrication, reactor design and operation, and {sup 99}Mo production processing use well-developed technologies that minimize the technological and licensing risks. There are no impediments that prevent this type of reactor, along with its collocated hot cell facility, from being designed, fabricated, and licensed today.

    The use of cyclotrons and synchrotrons to accelerate charged particles in hospital settings for the purpose of cancer therapy is increasing. Consequently, there is a growing demand from medical physicists, radiographers, physicians and oncologists for articles that explain the basic physical concepts of these technologies. There are unique advantages and disadvantages to all methods of acceleration. Several promising alternative methods of accelerating particles also have to be considered since they will become increasingly available with time; however, there are still many technical problems with these that require solving. This article serves as an introduction to this complex area of physics, and will be of benefit to those engaged in cancer therapy, or who intend to acquire such technologies in the future.

    Medical Informatics is the science and art of processing medical information. In this age of "Information Explosion" choosing the useful one is rather difficult, and there lies the scope of electronic database management. However, still many outstanding personnel related to the healthcare sector take pride in being "computer illiterate". The onus of the best use lies on the end-user health care providers only. Another term tele-health encompasses all the e-health and telemedicine services. Computer aided or assisted learning (CAL) is a computer based tutorial method that uses the computer to pose questions, provide remedial information and chart a student through a course. Now the emphasis in medical education, is on problem based learning (PBL) and there CAL could be of utmost help if used judiciously. Basic Medical Education and Research lays the foundation for advancing and applying proper healthcare delivery systems. There is no doubt that deep knowledge of anatomy is mandatory for successful surgery. Also, comprehensive knowledge of physiology is essential for grasping the principles of pathology and pharmacology adequately, to avoid incorrect and inadequate practice of medicine. Similarly, medical informatics is not just a subject to be learnt and forgotten after the first professional MBBS examination. The final aim of every student should not only be to become a good user but also an expert for advancing medical knowledge base through medical informatics. In view of the fast changing world of medical informatics, it is of utmost necessity to formulate a flexible syllabus rather than a rigid one. PMID:15907048

    The ethnomedical sciences are ethnobotany, ethnobiology, ethnopharmacology and phytotherapy. These fields are concerned with medicinal plants only, and the traditional medicines are mostly used. The author has extended the ethnomedical sciences by using traditional medicines in ethnomedicine, bacteriology, ethnobotany, and biochemistry, and thus ethnomedical sciences can be studied by a modern approach. The traditional doctors play a significant part in health care. They have both black and white patients, and they treat about 60%-70% of black patients in the country. Though they have been treating patients for many years, the patients' employers do not accept traditional doctors' medical certificates when they go back to work after treatment. In this case they first go to the traditional doctor for treatment and then go to an academically qualified medical practitioner solely because they need a medical certificate for their employers. Traditional doctors have been practising for centuries. In this country they are known as inyanga or ngaka and these designations mean doctor. Umthakathi or moloi means witch. Witchdoctor translates as Inyanga-mthakathi of ngaka-moloi. PMID:2493558

    In this image, an engineer is dwarfed by the parachute, which holds more air than a 280-square-meter (3,000-square-foot) house and is designed to survive loads in excess of 36,000 kilograms (80,000 pounds).

    The parachute, built by Pioneer Aerospace, South Windsor, Connecticut, has 80 suspension lines, measures more than 50 meters (165 feet) in length, and opens to a diameter of nearly 17 meters (55 feet). It is the largest disk-gap-band parachute ever built and is shown here inflated in the test section with only about 3.8 meters (12.5 feet) of clearance to both the floor and ceiling.

    The wind tunnel, which is 24 meters (80 feet) tall and 37 meters (120 feet) wide and big enough to house a Boeing 737, is part of the National Full-Scale Aerodynamics Complex, operated by the U.S. Air Force, Arnold Engineering Development Center.

    Over the past century basic nuclear science research has led to the use of radioactive isotopes into a wide variety of applications that touch our lives everyday. Some are obvious, such as isotopes for medical diagnostics and treatment. Others are less so, such as National/Global security issues. And some we take for granted, like the small amount of 241Am that is in every smoke detector. At the beginning of this century, we are in a position where the prevalence and importance of some applications of nuclear science are pushing the basic nuclear science community for improved models and nuclear data. Yet, at the same time, the push by the basic nuclear science community to study nuclei that are farther and farther away from stability also offer new opportunities for many applications. This talk will look at several global security applications of nuclear science, summarizing current R&D and need for improved nuclear data It will also look at how applications of nuclear science, such as to medicine, will benefit from the push for more and more powerful radioactive ion beam facilities.

    Several international standards and corresponding interpretation documents for quality management systems have been published. Although these standards are found useful to some extent, they are considered to be insufficient in several areas important for medical laboratories particularly in the pre- and post-examinational phases. The normative document for accreditation of laboratories (ISO/IEC Guide 25) is presently being revised and a document for medical laboratories (ISO/TC 212, CD 15189) is at draft stage. Both aim to include aspects of total quality management. The concept of total quality management is rather vague. Generally, its goal has been defined as "business excellence". This term, however, needs some explanation if applied to medical laboratories. Therefore, a project group of the European Confederation of Laboratory Medicine (ECLM) has developed a model for total quality management, which is based on a comprehensive management concept issued by the European Foundation for Quality Management. In the case of a medical laboratory, the term "business excellence" should be replaced by "good medical laboratory services". The proposed model could serve as a basis for future developments of total quality management standards in laboratory medicine. The goal of the "journey" should be clarified before it starts. To the best of our knowledge, this is the first attempt to develop a model of a good medical laboratory. PMID:9711429

    Although the use of performance indicators for the analytical (and highly measurable) phase of the medical laboratory process has had a long and successful history, it is now recognized that the value of a laboratory test is embedded in a system of care. This case study, using both documents and interview data, examines the approaches to accountability in the Ontario Medical Laboratory Sector, noting both the challenges and benefits. This sector relies heavily on the regulation instrument, including a requirement that all medical laboratories licensed by the provincial government must follow the guidelines set out by the Quality Management Program – Laboratory Services. We found the greatest challenges exist in the pre-analytical phase (where a large portion of total laboratory errors occur), particularly the interface between the laboratory and other providers.

    The science activities of the 1990's will require the analysis of complex phenomena and large diverse sets of data. In order to meet these needs, we must take advantage of advanced user interaction techniques: modern user interface tools; visualization capabilities; affordable, high performance graphics workstations; and interoperable data standards and translator. To meet these needs, we propose to adopt and upgrade several existing tools and systems to create an experimenter's laboratory for visualized interactive science. Intuitive human-computer interaction techniques have already been developed and demonstrated at the University of Colorado. A Transportable Applications Executive (TAE+), developed at GSFC, is a powerful user interface tool for general purpose applications. A 3D visualization package developed by NCAR provides both color shaded surface displays and volumetric rendering in either index or true color. The Network Common Data Form (NetCDF) data access library developed by Unidata supports creation, access and sharing of scientific data in a form that is self-describing and network transparent. The combination and enhancement of these packages constitutes a powerful experimenter's laboratory capable of meeting key science needs of the 1990's. This proposal encompasses the work required to build and demonstrate this capability.

The combination and enhancement of these packages constitutes a powerful experimenter's laboratory capable of meeting key science needs of the 1990's. This proposal encompasses the work required to build and demonstrate this capability.

    2013-01-01

    The Mars Science Laboratory spacecraft, carrying the Curiosity rover to Mars, hit the top of the Martian atmosphere just 200 meters from where it had been predicted more than six days earlier, and 2.6 million kilometers away. This un-expected level of accuracy was achieved by a combination of factors including: spacecraft performance, tracking data processing, dynamical modeling choices, and navigation filter setup. This paper will describe our best understanding of what were the factors that contributed to this excellent interplanetary trajectory prediction performance. The accurate interplanetary navigation contributed to the very precise landing performance, and to the overall success of the mission.

    ELVIS (Experimenter's Laboratory for Visualized Interactive Science) is an interactive visualization environment that enables scientists, students, and educators to visualize and analyze large, complex, and diverse sets of scientific data. It accomplishes this by presenting the data sets as 2-D, 3-D, color, stereo, and graphic images with movable and multiple light sources combined with displays of solid-surface, contours, wire-frame, and transparency. By simultaneously rendering diverse data sets acquired from multiple sources, formats, and resolutions and by interacting with the data through an intuitive, direct-manipulation interface, ELVIS provides an interactive and responsive environment for exploratory data analysis.

  4. Social Networks in the Virtual Science Laboratory

    Chin, George; Myers, James D.; Hoyt, David W.

    2002-08-01

    Located at the Pacific Northwest National Laboratory (PNNL), the High Field Magnetic Resonance Facility (HFMRF) houses 11 nuclear magnetic resonance (NMR) spectrometers. Additionally, the Virtual Nuclear Magnetic Resonance Facility (VNMRF) provides on-line Internet access to these HFMRF spectrometers. Through the VNMRF and its suite of computer-supported cooperative work (CSCW) tools, researchers may collaboratively set the controls of an NMR spectrometer, execute an NMR experiment, acquire data, analyze results, and communicate with other researchers all from the comforts of their home institutions and their own offices. Virtual science laboratories like the VNMRF promote a compelling vision. Consistent with Wulf's notion of a "collaboratory," a virtual science laboratory is a "'center without walls', in which the nation's researchers can perform their research without regard to geographical location." Such a laboratory strives to provide an open research environment in which scientists from different disciplines may collaborate on advanced research using leading-edge instruments and tools, while reducing the physical, organizational, and political boundaries that confront researchers as they amass their collective skills, capabilities, and brainpower to solve the world's most challenging scientific problems. In this article, we describe the social networks that have emerged from the VNMRF and the impacts and influences that CSCW technologies have had upon those networks. The development of social networks depends on various factors including personal and professional objectives, work functions, organizational roles, and afforded collaborative capabilities. As such, our results serve as a useful point of comparison and contrast in the analysis of social networks and CSCW impacts that evolve from scientific contexts as well as from other collaborative settings such as in business and education.

  8. Mars Science Laboratory Planetary Protection Status

    NASA Astrophysics Data System (ADS)

    Koukol, Robert; Morales, Fabian; Benardini, James Nick; Schubert, Wayne

    The Mars Science Laboratory (MSL) Project is a Mars rover project now scheduled for a 2011 launch. The MSL flight system consists of a cruise stage; an entry, descent and landing system (EDL); and a Radioisotope Thermoelectric Generator (RTG) powered roving science vehicle that will land on the surface and perform geological science. None of the instruments in the Rover payload are life detection experiments for the purposes of planetary protection (PP). Nevertheless, a goal of the mission is to access areas of interest, including possible subsurface special regions, and to obtain and scientifically examine samples. Therefore the project has been categorized by NASA as COSPAR PP Category IVc. The entire flight system is subject to microbial reduction requirements, with additional specific emphasis on the sample acquisition and handling chain. Prior to the final design of the flight system, MSL performed analyses to show that the elements of the flight system will not cause a high probability of inadvertent biological contamination to Mars. The project is using a pinpoint landing system and will land in a non-special region on Mars, agreed to by the NASA Planetary Protection Officer. MSL has completed an approved Planetary Protection Plan and a PP Implementation Document. Planetary protection activities have begun with the start of flight system fabrication and assembly. The status of the PP activities will be reported.

  9. Distractions in the School Science Laboratory

    NASA Astrophysics Data System (ADS)

    Hamza, Karim M.

    2013-08-01

    In this article, I make a case for the potential educative worth of distractions for learning science in the school laboratory. Distractions are operationalized as experiences lying outside the main purpose of the laboratory activity, thereby diverting students' attention from that purpose. Through a practical epistemology analysis, I examined in close detail the conversations of three groups of high school students trying to explain how a real galvanic cell works. The three groups experienced the same two distractions, (1) a nonworking light-emitting diode and (2) negative readings on a voltmeter. The analysis reveals how one of the groups, through a series of contingencies, successively made the two distractions continuous with the main purpose of the activity. In the remaining two groups, no such continuity was established. The results show that (a) experiences initially being distracting, perplexing, and confusing may indeed acquire significance for the students' possibilities of coping with the main purpose of the activity but that (b) the outcome is highly contingent on the particular experiences drawn upon by the students to cope with the distractions. Consequently, I discuss ways in which teachers may turn distractions encountered in laboratory activities into educative experiences for more than a few lucky students.

    A biobank facility is one of the most valuable means that academic medical organizations have to offer researchers for improving the competitiveness of their medical research. We describe the implementation of our institutional biobank. Our efforts focused on the design and equipment of work areas, staff training, quality control, bioethical and regulatory issues, generating research collaborations and developing funding strategies. We implemented an institutional biobank at the School of Medicine of the Autonomous University of Nuevo León, Mexico. The biobank has supported more than a dozen research protocols with over 3 000 individuals enrolled and almost 6 000 sampled biospecimens stored. The institutional biobank has become an essential bridge and effective catalyst for research synergies between basic and clinical sciences and it is on its way to becoming a National Laboratory.

    The Organic Check Material (OCM) has been developed for use on the Mars Science Laboratory mission to serve as a sample standard for verification of organic cleanliness and characterization of potential sample alteration as a function of the sample acquisition and portioning process on the Curiosity rover. OCM samples will be acquired using the same procedures for drilling, portioning and delivery as are used to study martian samples with The Sample Analysis at Mars (SAM) instrument suite during MSL surface operations. Because the SAM suite is highly sensitive to organic molecules, the mission can better verify the cleanliness of Curiosity's sample acquisition hardware if a known material can be processed through SAM and compared with the results obtained from martian samples.

  15. 2011 Mars Science Laboratory Launch Period Design

    NASA Technical Reports Server (NTRS)

    Abilleira, Fernando

    2011-01-01

    The Mars Science Laboratory mission, set to launch in the fall of 2011, has the primary objective of landing the most advanced rover to date to the surface of Mars to assess whether Mars ever was, or still is today, able to sustain carbon-based life. Arriving at Mars in August 2012, the Mars Science Laboratory will also demonstrate the ability to deliver large payloads to the surface of Mars, land more accurately (than previous missions) in a 20-km by 25-km ellipse, and traverse up to 20 km. Following guided entry and parachute deployment, the spacecraft will descend on a parachute and a Powered Descent Vehicle to safely land the rover on the surface of Mars. The launch/arrival strategy is driven by several key requirements, which include: launch vehicle capability, atmosphere-relative entry speed, communications coverage during Entry, Descent and Landing, latitude accessibility, and dust storm season avoidance. Notable among these requirements is maintaining a telecommunications link from atmospheric entry to landing plus one minute, via a Direct-To-Earth X-band link and via orbital assets using an UHF link, to ensure that any failure during Entry, Descent and Landing can be reconstructed in case of a mission anomaly. Due to concerns related to the lifetime of the relay orbiters, two additional launch/arrival strategies have been developed to improve Entry, Descent, and Landing communications. This paper discusses the final launch/arrival strategy selected prior to the launch period down-selection that is scheduled to occur in August 2011. It is also important to note that this paper is an update to Ref. 1 in that it includes two new Type 1 launch periods and drops the Type 2 launch period that is no longer considered.

    The year 2014 is an important year because it will mark the 25th Anniversary of the founding of the African Association of Physiological Sciences (AAPS) and initial talks to launch the International Society for Pathophysiology (ISP). Both these organizations had a foothold in Finland and both occurred during the IUPS Centennial Celebration Congress in 1989. The congress was hosted by the Finnish Physiological Society in Helsinki, Finland in July 1989. For both organizations, Prof OsmoHänninen was instrumental in the launching and inauguration of AAPS and also to initiate the creation of ISP. In order to celebrate the 25th Anniversaries of both organizations it was decided to hold the ISP2014 congress on the African soil. Hence in 2004, at the 4th international congress of AAPS held in Morocco, Wail Benjeloun.the then secretary general of AAPS, submitted successfully a bid to host ISP2014 in Morocco. Following the inauguration of AAPS in Helsinki, the 1st Congress of AAPS was held in Nairobi, Kenya in 1992 where the Constitution of AAPS was drawn up. The Constitution was adopted at the 2nd congress of AAPS in Durban, South Africa in 1997. Following this congress, the next congress, as scheduled, was held in Pretoria, South Africa in 2000. The last congress (6th) of AAPS was held on 1-5 September 2012 in Ismailia, Egypt. This was an historical congress because of many reasons and amongst these was the appointment of Anthony B. Ebeigbe, Department of Physiology, University of Benin, Nigeria as its first Editor-in-Chief of its official journal, the Journal of the African association of Physiological Sciences (JAAPS). He successfully published the first issue in June 2013, as mandated in Ismailia. The World's medicine has its initial root in Africa and in fact it was in Memphis, Egypt as early as 2700 BC. During the Ptulomaic period the seat of medicine was in Alexandria, Egypt and Medical knowledge then spread to the Greeks 330 BC. Many western medical scientists

  17. Mars Science Laboratory Rover Actuator Thermal Design

    2010-01-01

    NASA will launch a 900 kg rover, part of the Mars Science Laboratory (MSL) mission, to Mars in October of 2011. The MSL rover is scheduled to land on Mars in August of 2012. The rover employs 31, electric-motor driven actuators to perform a variety of engineering and science functions including: mobility, camera pointing, telecommunications antenna steering, soil and rock sample acquisition and sample processing. This paper describes the MSL rover actuator thermal design. The actuators have stainless steel housings and planetary gearboxes that are lubricated with a "wet" lubricant. The lubricant viscosity increases with decreasing temperature. Warm-up heaters are required to bring the actuators up to temperature (above -55 C) prior to use in the cold wintertime environment of Mars (when ambient atmosphere temperatures are as cold as -113 C). Analytical thermal models of all 31 MSL actuators have been developed. The actuators have been analyzed and warm-up heaters have been designed to improve actuator performance in cold environments. Thermal hardware for the actuators has been specified, procured and installed. This paper presents actuator thermal analysis predicts, and describes the actuator thermal hardware and its operation. In addition, warm-up heater testing and thermal model correlation efforts for the Remote Sensing Mast (RSM) elevation actuator are discussed.

    This is an STS-66 mission onboard photo of the Space Shuttle Orbiter Atlantis showing the payload of the third Atmospheric Laboratory for Applications and Science (ATLAS-3) mission. During the ATLAS missions, international teams of scientists representing many disciplines combined their expertise to seek answers to complex questions about the atmospheric and solar conditions that sustain life on Earth. The ATLAS program specifically investigated how Earth's middle and upper atmospheres and climate are affected by by the sun and by products of industrial and agricultural activities on Earth. Thirteen ATLAS instruments supported experiments in atmospheric sciences, solar physics, space plasma physics, and astronomy. The instruments were mounted on two Spacelab pallets in the Space Shuttle payload bay. The ATLAS-3 mission continued a variety of atmospheric and solar studies to improve understanding of the Earth's atmosphere and its energy input from the sun. A key scientific objective was to refine existing data on variations in the fragile ozone layer of the atmosphere. The Orbiter Atlantis was launched on November 3, 1994 for the ATLAS-3 mission (STS-66).

    On November 26, 2011, NASA launched a large (900 kg) rover as part of the Mars Science Laboratory (MSL) mission to Mars. The MSL rover is scheduled to land on Mars on August 5, 2012. Prior to launch, the Rover was successfully operated in simulated mission extreme environments during a 16-day long Rover System Thermal Test (STT). This paper describes the MSL Rover STT, test planning, test execution, test results, thermal model correlation and flight predictions. The rover was tested in the JPL 25-Foot Diameter Space Simulator Facility at the Jet Propulsion Laboratory (JPL). The Rover operated in simulated Cruise (vacuum) and Mars Surface environments (8 Torr nitrogen gas) with mission extreme hot and cold boundary conditions. A Xenon lamp solar simulator was used to impose simulated solar loads on the rover during a bounding hot case and during a simulated Mars diurnal test case. All thermal hardware was exercised and performed nominally. The Rover Heat Rejection System, a liquid-phase fluid loop used to transport heat in and out of the electronics boxes inside the rover chassis, performed better than predicted. Steady state and transient data were collected to allow correlation of analytical thermal models. These thermal models were subsequently used to predict rover thermal performance for the MSL Gale Crater landing site. Models predict that critical hardware temperatures will be maintained within allowable flight limits over the entire 669 Sol surface mission.

    2012-01-01

    Background: Regarding the importance of probiotics in prevention of different diseases, the knowledge of people particularly health-related professionals about the beneficial effects and availability of probiotic products is important. Considering the limited studies, the present study was conducted to assess the knowledge of medical sciences students as future provider of health information about probiotics in Tabriz, Iran. Methods: This cross-sectional study was carried out on 296 medical sciences students from different faculty majors with mean age of 22 ± 4 years. The students completed two self-administered questionnaires; the one was about the demographic characteristics and the other one with nine closed questions as for knowledge as well as probiotics and their health effects and 2 questions related to availability of probiotic products. Scoring of 9 knowledge questions was divided to three sections 0-3, 4-6, 7-9 and classified as poor, acceptable and good, respectively. The Chi-square test was used to examine the differences in knowledge of the students across different gender, major and degree groups. Results: Six percent of students had poor, 43% acceptable, and 51% good knowledge. Total mean±(SD) of knowledge was 6.25 ±1.6 . Answers of students about the availability of probiotic products were 36.9% low, 48.1% moderate, and 15% high. Comparison of knowledge result between different major and degree groups was statistically significant (P<0.05). Conclusion: Although students had approximately acceptable level of knowledge about probiotics and their health effects, their awareness about common available form of probiotic products was low. The use of efficient co-educational materials such as teaching new findings for students may be beneficial. PMID:24688923

    MSLICE (Mars Science Laboratory InterfaCE) is the tool used by scientists and engineers on the Mars Science Laboratory rover mission to visualize the data returned by the rover and collaboratively plan its activities. It enables users to efficiently and effectively search all mission data to find applicable products (e.g., images, targets, activity plans, sequences, etc.), view and plan the traverse of the rover in HiRISE (High Resolution Imaging Science Experiment) images, visualize data acquired by the rover, and develop, model, and validate the activities the rover will perform. MSLICE enables users to securely contribute to the mission s activity planning process from their home institutions using off-the-shelf laptop computers. This software has made use of several plug-ins (software components) developed for previous missions [e.g., Mars Exploration Rover (MER), Phoenix Mars Lander (PHX)] and other technology tasks. It has a simple, intuitive, and powerful search capability. For any given mission, there is a huge amount of data and associated metadata that is generated. To help users sort through this information, MSLICE s search interface is provided in a similar fashion as major Internet search engines. With regard to the HiRISE visualization of the rover s traverse, this view is a map of the mission that allows scientists to easily gauge where the rover has been and where it is likely to go. The map also provides the ability to correct or adjust the known position of the rover through the overlaying of images acquired from the rover on top of the HiRISE image. A user can then correct the rover s position by collocating the visible features in the overlays with the same features in the underlying HiRISE image. MSLICE users can also rapidly search all mission data for images that contain a point specified by the user in another image or panoramic mosaic. MSLICE allows the creation of targets, which provides a way for scientists to collaboratively name

    I have been involved in medical cooperation programs between Myanmar and Japan for over 10 years. The purpose of the first visit to Myanmar was the investigation of hepatitis C spreading among thalassemia patients. I learned that the medical system was underdeveloped in this country, and have initiated several cooperation programs together with Professor Shigeru Okada, such as the "Protection against hepatitis C in Myanmar", "Scientist exchange between the Ministry of Health, Myanmar and Okayama University", and "Various activities sponsored by a Non-Profit Organization". As for clinical laboratories, the laboratory system itself is pre-constructed and the benefit of a clinical laboratory in modern medicine is not given to patients in Myanmar. The donation of drugs and reagents for laboratory tests is helpful, but it will be more helpful to assist the future leaders to learn modern medicine and develop their own various systems to support modern medicine. Our activity in the cooperation program is described. PMID:22568086

    Medical research and health care highly depend on the use of information technology. There is a wide range of application systems (patient administration system, laboratory information system, communication server etc.) and heterogeneous data types (administrative data, clinical data, laboratory data, image data, genomic data etc.). Students and researchers do not often have the possibility to use productive application systems of e.g. hospitals or medical practices to gain practical experiences or examine new components and technologies. Therefore, the aim of this project is to develop a dedicated laboratory environment for patient health care and clinical research. Essential application systems were identified and a suitable architecture was designed for this purpose. It is accompanied by a teaching plan that considers learning modules for bachelor and master degrees in medical informatics. We implemented the laboratory environment called MI-Lab with multiple free and open source software components. All components are installed on virtual machines and/or Docker containers. This modular architecture creates a flexible system which can be deployed in various scenarios. The preliminary evaluation results suggests that laboratory environments like MI-Lab work well in teaching practical aspects of medical informatics and are widely accepted by students. PMID:27577339

    Mars Science Laboratory (MSL) is one of the most complex spacecrafts in the history of mankind. Due to the nature of its complexity, a large number of flight software (FSW) requirements have been written for implementation. In practice, these requirements necessitate very complex and very precise flight software with no room for error. One of flight software's responsibilities is to be able to boot up and check the state of all devices on the spacecraft after the wake up process. This boot up and initialization is crucial to the mission success since any misbehavior of different devices needs to be handled through the flight software. I have created a test toolkit that allows the FSW team to exhaustively test the flight software under variety of different unexpected scenarios and validate that flight software can handle any situation after booting up. The test includes initializing different devices on spacecraft to different configurations and validate at the end of the flight software boot up that the flight software has initialized those devices to what they are suppose to be in that particular scenario.

  11. Mars Science Laboratory Rover Mobility Bushing Development

    Riggs, Benjamin

    2008-01-01

    NASA s Mars Science Laboratory (MSL) Project will send a six-wheeled rover to Mars in 2009. The rover will carry a scientific payload designed to search for organic molecules on the Martian surface during its primary mission. This paper describes the development and testing of a bonded film lubricated bushing system to be used in the mobility system of the rover. The MSL Rover Mobility System contains several pivots that are tightly constrained with respect to mass and volume. These pivots are also exposed to relatively low temperatures (-135 C) during operation. The combination of these constraints led the mobility team to consider the use of solid film lubricated metallic bushings and dry running polymeric bushings in several flight pivot applications. A test program was developed to mitigate the risk associated with using these materials in critical pivots on the MSL vehicle. The program was designed to characterize bushing friction and wear performance over the expected operational temperature range (-135 C to +70 C). Seven different bushing material / lubricant combinations were evaluated to aid in the selection of the final flight pivot bushing material / lubricant combination.

    The Mars Science Laboratory (MSL) team is sending the rover, Curiosity, to Mars, and therefore is physically and technically complex. During my stay, I have assisted the MSL Flight Software (FSW) team in implementing functional test scripts to ensure that the FSW performs to the best of its abilities. There are a large number of FSW requirements that have been written up for implementation; however I have only been assigned a few sections of these requirements. There are many stages within testing; one of the early stages is FSW Internal Testing (FIT). The FIT team can accomplish this with simulation software and the MSL Test Automation Kit (MTAK). MTAK has the ability to integrate with the Software Simulation Equipment (SSE) and the Mission Processing and Control System (MPCS) software which makes it a powerful tool within the MSL FSW development process. The MSL team must ensure that the rover accomplishes all stages of the mission successfully. Due to the natural complexity of this project there is a strong emphasis on testing, as failure is not an option. The entire mission could be jeopardized if something is overlooked.

    Clinical skills laboratories have been established in medical institutions as facilities for simulation-based medical education (SBME). SBME is believed to be superior to the traditional style of medical education from the viewpoint of the active and adult learning theories. SBME can provide a learning cycle of debriefing and feedback for learners as well as evaluation of procedures and competency. SBME offers both learners and patients a safe environment for practice and error. In a full-environment simulation, learners can obtain not only technical skills but also non-technical skills, such as leadership, team work, communication, situation awareness, decision-making, and awareness of personal limitations. SBME is also effective for integration of clinical medicine and basic medicine. In addition, technology-enhanced simulation training is associated with beneficial effects for outcomes of knowledge, skills, behaviors, and patient-related outcomes. To perform SBME, effectively, not only simulators including high-fidelity mannequin-type simulators or virtual-reality simulators but also full-time faculties and instructors as professionals of SBME are essential in a clinical skills laboratory for SBME. Clinical skills laboratory is expected to become an integrated medical education center to achieve continuing professional development, integrated learning of basic and clinical medicine, and citizens' participation and cooperation in medical education.

    Introduction: The efficient use of libraries can be an important factor in determining the educational quality of Universities. Therefore, investigation and identification of factors affecting library anxiety becomes increasingly necessary. The purpose of this research is to determine the factors effecting library anxiety of students in Isfahan University of Medical Sciences and Shiraz University of Medical Sciences. Materials and Methods: This was an applied survey research using Bostick's Library Anxiety questionnaire as data gathering tool. The statistical population consisted of all students of Isfahan University of Medical Sciences and Shiraz University of Medical Sciences (15011 students) with the sample size of 375 using stratified random sampling. The validity of data gathering tool was confirmed by experts in the library and information science and its reliability was determined by Cronbach's alpha (r = 0.92). Descriptive statistics (frequency, percentage, mean and standard deviation) and inferential statistics (t-test and ANOVA) were used for data analysis using SPSS 18 software. Results: Findings showed that the mean of library anxiety score was 2.68 and 2.66 for students of Isfahan University of Medical Sciences and Shiraz University of Medical Sciences respectively which is above average (2.5). Furthermore, age and gender had no meaningful effect on the library anxiety of students of Isfahan University of Medical Sciences, but gender had a meaningful effect on library anxiety of students of Shiraz University of Medical Sciences while age had no such effect. Conclusion: The results showed that the mean of factors effecting library anxiety in students of Isfahan University of Medical Sciences and students of Shiraz University of Medical Sciences is higher than average and therefore not satisfactory and only factors relating to feeling comfortable in the library is lower than average and somewhat satisfactory.

    Sarri, C; Eng, E; Runyan, C

    1991-01-01

    Housekeepers' injury experiences in medical laboratories have not been reported previously. Review of injury incident reports for housekeepers assigned to medical research laboratories in a major university revealed an incidence rate of 46 injuries per 100 housekeepers per year from 1985 to 1988. Thirty-seven percent of the injuries were cuts and punctures, with 70% of these attributable to glass, needles, or cutting instruments. In a survey, 65% of housekeepers indicated that they do not always report their injuries, but the injury pattern they described paralleled those recorded in incident reports. Housekeepers identified behavioral and environmental factors that can contribute to laboratory injuries, including: lack of knowledge; failure to use protective equipment; carelessness; and, "sharps" (ie, sharp needles or glass) in the trash.

    This article describes a new set of revised standards for the medical laboratory, which have been produced by Clinical Pathology Accreditation (UK) Ltd (CPA). The original standards have been in use since 1992 and it was recognised that extensive revision was required. A standards revision group was established by CPA and this group used several international standards as source references, so that the resulting new standards are compatible with the most recent international reference sources. The aim is to make the assessment of medical laboratories as objective as possible in the future. CPA plans to introduce these standards in the UK in 2003 following extensive consultation with professional bodies, piloting in selected laboratories, and training of assessors. PMID:12354795

    The Curiosity rover landed successfully in Gale Crater, Mars on August 5, 2012. This event was a dramatic high point in the decade long effort to design, build, test and fly the most sophisticated scientific vehicle ever sent to Mars. The real achievements of the mission have only just begun, however, as Curiosity is now searching for signs that Mars once possessed habitable environments. The Mars Science Laboratory Project has been one of the most ambitious and challenging planetary projects that NASA has undertaken. It started in the successful aftermath of the 2003 Mars Exploration Rover project and was designed to take significant steps forward in both engineering and scientific capabilities. This included a new landing system capable of emplacing a large mobile vehicle over a wide range of potential landing sites, advanced sample acquisition and handling capabilities that can retrieve samples from both rocks and soil, and a high reliability avionics suite that is designed to permit long duration surface operations. It also includes a set of ten sophisticated scientific instruments that will investigate both the geological context of the landing site plus analyze samples to understand the chemical & organic composition of rocks & soil found there. The Gale Crater site has been specifically selected as a promising location where ancient habitable environments may have existed and for which evidence may be preserved. Curiosity will spend a minimum of one Mars year (about two Earth years) looking for this evidence. This paper will report on the progress of the mission over the first few months of surface operations, plus look retrospectively at lessons learned during both the development and cruise operations phase of the mission..

    One of the major scientific challenges in the 21st century is to improve our understanding on the evolution of the water cycle associated with the climate variability. Main issues concern the prediction of i) the water resource and the access to drinkable water and ii) the extreme events, both droughts and floods. Observation strategies covering a wide range of space and time scales must therefore be set up, while continuing advanced research on the involved mechanisms and developing integrated modeling approaches. Within this general context, the present work relies on three natural observatories, located in West Africa, Worldwide Glaciers, and in Mediterranean region, managed at LTHE (Laboratoire d'étude des Transferts en Hydrologie et Environnement; Grenoble, France) and gathered at OSUG (Observatoire des Sciences de l'Univers; Grenoble, France). Their scientific objectives aim at improving the understanding of the water cycle functioning, providing water and mass balances for multi-scale basin sizes, and evaluating the hydrological impacts of the evolving climate. Water cycle variables (precipitation; soil moisture; snow cover; discharge; air and river temperatures; suspended material; etc …) are observed and recorded in 3 different databases built under specific technical constraints linked to the respective partnerships of the natural observatories. Each of the observatories has its own database, and modeling tools were developed separately leading to important efforts often duplicated. Therefore, there was a need to build an integrated cyber-infrastructure to provide access to data, and to shared tools and models that enable the understanding of the water cycle. This is the project called OLES, for Online Laboratory for Environmental Sciences. Focused on the understanding of the water cycle under contrasted climates, OLES facilitates the work of the scientific community and then, help interactions between the research community and water agencies or

  2. Rationalization of medical care: the role of the National Laboratories

    NASA Astrophysics Data System (ADS)

    Re', Richard N.

    1994-12-01

    The cost of medical care in the United States is deemed to be excessive by government and business. The causes for this high cost of care are multiple, but the argument that technology is the leading cause has been made. It is argued here that technology, properly employed, can actually be a major component of the solution to rising to health care costs. Because the National Laboratories are a repository for many of the technologies needed to lower health care costs while improving health care quality, a national effort linking these laboratories with university and other academic medical centers, industry, and the National Institutes of Health should be undertaken. The development of a technology roadmap for health care technologies is an important part of this effort.

    Purpose To address the shortage of laboratory scientists in Botswana, an innovative, one-year academic bridging program was initiated at the University of Botswana, to advance diploma-holding laboratory technicians towards becoming laboratory scientists holding Bachelor’s degrees. An evaluation was conducted, which described the outcomes of the program and the lessons learned from this novel approach to meeting human resource needs. Methods This was a cross-sectional, mixed-methods evaluation. Qualitative interviews were conducted with graduates of the Bachelor of Science (BSc) Medical Laboratory Sciences (MLS) bridging program, along with the graduates’ current supervisors, and key informants who were involved in program development or implementation. The quantitative data collected included a written questionnaire, completed by program graduates, with a retrospective pre-test/post-test survey of graduates’ confidence, in terms of key laboratory competencies. Results The BSc MLS bridging program produced thirty-three laboratory scientists over 3 years. There was a significant increase in confidence among graduates, for specified competencies, after the program (P<0.05). Graduates reported acquiring new skills and, often, accepting new responsibilities at their former workplace, particularly in relationship to leadership and management. Five graduates enrolled in advanced degree programs. Most graduates assumed increased responsibility. However, only two graduates were promoted after completing the training program. The lessons learned include: the importance of stakeholder involvement, the need for data to identify local needs, financial sustainability, catering for the needs of adult learners, and ensuring a technically challenging work environment, conducive to the application of skills learned during training. Conclusion A strong public health and clinical laboratory system is essential for the rapid detection and control of emerging health threats, and

    The number of physicians engaged in basic sciences and teaching is sharply decreasing in Japan. To alleviate this shortage, central government has increased the quota of medical students entering the field. This study investigated medical students' interest in basic sciences in efforts to recruit talent. A questionnaire distributed to 501 medical students in years 2 to 6 of Juntendo University School of Medicine inquired about sex, grade, interest in basic sciences, interest in research, career path as a basic science physician, faculties' efforts to encourage students to conduct research, increases in the number of lectures, and practical training sessions on research. Associations between interest in basic sciences and other variables were examined using χ(2) tests. From among the 269 medical students (171 female) who returned the questionnaire (response rate 53.7%), 24.5% of respondents were interested in basic sciences and half of them considered basic sciences as their future career. Obstacles to this career were their original aim to become a clinician and concerns about salary. Medical students who were likely to be interested in basic sciences were fifth- and sixth-year students, were interested in research, considered basic sciences as their future career, considered faculties were making efforts to encourage medical students to conduct research, and wanted more research-related lectures. Improving physicians' salaries in basic sciences is important for securing talent. Moreover, offering continuous opportunities for medical students to experience research and encouraging advanced-year students during and after bedside learning to engage in basic sciences are important for recruiting talent.

    The purpose of this study was to identify science teachers' perceptions concerning the use of technology in science laboratories and identify teachers' concerns and recommendations for improving students' learning. Survey methodology with electronic delivery was used to gather data from 164 science teachers representing Texas public schools. The data confirmed that weaknesses identified in the 1990s still exist. Lack of equipment, classroom space, and technology access, as well as large numbers of students, were reported as major barriers to the implementation of technology in science laboratories. Significant differences were found based on gender, grade level, certification type, years of experience, and technology proficiency. Females, elementary teachers, traditionally trained teachers, and less experienced teachers revealed a more positive attitude toward the use of technology in science laboratories. Participants in this study preferred using science software simulations to support rather than replace traditional science laboratories. Teachers in this study recommended professional development programs that focused on strategies for a technology integrated classroom.

    Wiltshire, J

    1998-09-01

    Drawing on the work of Evelyn Fox Keller, this paper examines the notion of 'objectivism' and suggests that medicine as a science is premised upon the denial of common mortality. Alternative models for medicine are then examined, including the 'romantic science' of Oliver Sacks, and the paper concludes with a brief discussion of nursing as a key concept in the articulation of a more comprehensive medicine of the future.

    1979-01-01

    A growing number of clinical laboratories use computerized laboratory information systems for data acquisition, data management, and report generation. Although the research potential of the large machine-readable data bases generated by these systems is often mentioned, there has been comparatively little actual use of data bases for research. This presentation will briefly present four research studies using laboratory data bases and discuss the problems which were encountered in acquiring, characterizing, and maintaining these data bases. The use of medical records, pharmacy, financial, and other machine-readable data bases available in many hospitals will be discussed. The problems encountered with the use of coded diagnosis and operations records in combination with laboratory data are of particular concern. Finally, the use of clinical laboratory systems in conjunction with total hospital information systems for the accumulation of research data bases will be illustrated. It is particularly important that the lessons learned to date be incorporated into planning for the use of hospital information systems in research so that the enormous potential of these systems can be realized.

    2008-03-01

    The behavioral sciences are taught in medical curricula around the world. In the current paper psychologists teaching in medical schools in Australia, Mexico, Saudi Arabia, Thailand, the United Kingdom and the United States share their experience and reflections. Whilst direct comparisons between countries are not made, the themes that are evident within and between accounts are instructive. As behavioral scientists around the globe are struggling to maintain a presence in medical education many of the reasons behind this are shared, regardless of the country. Challenges discussed include those related to the impact of unrealized potential contributions of psychologists as health care professionals, teaching of behavioral sciences by other professions, domination of the biomedical model without a corresponding recognition of psychology as science, and modern medical pedagogies such as problem-based learning, which favor biomedicine. Systemic and political barriers over which we as a discipline may have little control are also highlighted. PMID:19104953

    This article briefly reviews the impact of regularly promoted alternative therapies within portuguese society. The origins, attractions and acceptance of alternative therapies, homeopathic included, are discussed. Recent homeopathic studies published in renowned scientific journals provoked comments and reports claiming for more objective explanations and better criticism. Accordingly, homeopathy is presently an unacceptable system with no physical basis, supported by inexplicable observations and a mixture of magic effects. Also alternatives therapies may provide an area of conflict with health and medical care, particularly in most severe diseases that require advanced resources of orthodox medicine. Improved education of the population, more qualified medical personal, and better understanding of medical problems, difficulties and progress by the media are final recommendations. PMID:2077840

    While historians of science have demonstrated that in the late eighteenth century the emergence of the human sciences went along with the sexualization and medicalization of women, they paid almost no attention to the development of a medical knowledge on male (in)fertility. This paper argues that in the early twentieth century, the scientific investigation of the male role in reproduction was due to the rise of eugenics and the racial sciences. In order to illustrate this relation, I will discuss how in the context of the Nazi population and racial policy new research outcomes in the field of male (in)fertiliy research were achieved. More generally, I want to show that the transformation of man into a reproductive being and an object of medical knowledge is not only relevant for the history of reproductive medicine, but also for the history of the human sciences in the twentieth century.

  8. The place of behavioral science in medical education and practice.

    PubMed

    Bolman, W M

    1995-10-01

    Medicine and medical practice have undergone dramatic changes in the recent past. Technological advances have exceeded the norms of social thought (e.g., frozen embryos, surrogate motherhood, assisted suicide, and the right to die), and there has been a loss of professional control of the provision of medical services because of an inability to control the costs of technology and the patterns of practice. These and related changes find the profession of medicine, including medical education, without the necessary theory and content to adapt. The author explains why this situation makes it more necessary than ever to develop and upgrade the teaching of behavioral sciences in the medical curriculum, even though these disciplines' breadth and comparative lack of definition create special problems for the teaching and learning of behavioral concepts and their application to medical practice. The behavioral sciences are needed in medicine because their role is not that of a technologically defined knowledge area but rather that of a process or functional area that mediates between the patient as a person and the delivery of medical care. The author presents concepts, a diagram, and teaching examples that explain the characteristics of behavioral sciences and illustrate the necessity for including them in the curriculum. He concludes by urging the leaders of academic medicine to find practical ways to transmit an awareness of behavioral sciences' crucial role in patient care so that tomorrow's physicians can function more fully in the complex arena of clinical reality.

    The Odyssey Missions orbital maps of near surface ice abundance using neutron spectroscopy (Boynton et al., 2002), the Mars Exploration Rover s confirmation of aqueous processing (Squyres et al., 2004), and the Mars Express detailed infrared maps of specific mineral types that were likely formed in aqueous environments (Bibring et al., 2005) have dramatically expanded our tool set for understanding of aqueous processes on Mars. The 2009 Mars Science Laboratory is designed to extend the "follow the water" crosscutting theme of the Mars Exploration Program toward an even more detailed exploration of habitability - the potential of the Mars environment to support life. The next steps in understanding the habitability of Mars are a more detailed in situ analysis of the chemical state of elements such as C, H, O, N, S, P, Ca, and Fe that are essential for terrestrial life. Of particular interest are experiments that establish definitive mineralogy for a wider range of compounds and those that implement a more comprehensive and sensitive search for organic molecules both in the atmosphere and in surface or near surface rocks, soils, and fines. The recent reports of atmospheric methane in the Martian atmosphere make the organics exploration even more compelling. The substantial mass and power resources of MSL combined with its mobility and powerful sample acquisition and processing tools will enable it to locate a variety of near-surface samples and analyze these in some detail. NASA is presently considering the possibility of landing a second MSL rover in 2011.

    Since diversity in the workplace began receiving scholarly attention in the late 1980s, many corporations and institutions have invested in programs to address and manage diversity. We encourage laboratory animal science to address the challenges and to build on the strengths that personal diversity brings to our field and workplaces. Diversity is already becoming increasingly relevant in the workplace and the laboratory animal science field. By addressing issues related to diversity, laboratory animal science could benefit and potentially fulfill its goals more successfully. To date, diversity has received minimal attention from the field as a whole. However, many individuals, workplaces, and institutions in industry, academia, and the uniformed services that are intimately involved with the field of laboratory animal science are actively addressing issues concerning diversity. This article describes some of these programs and activities in industry and academia. Our intention is that this article will provide useful examples of inclusion-promoting activities and prompt further initiatives to address diversity awareness and inclusion in laboratory animal science.

    Objective Learning environment has a significant role in determining students’ academic achievement and learning. The aim of this study is to investigate the viewpoints of undergraduate medical sciences students on the learning environment using the Dundee Ready Education Environment Measure (DREEM) at Rafsanjan University of Medical Sciences (RUMS). Methods The descriptive cross-sectional study was performed on 493 medical sciences students in the following majors: nursing, midwifery, radiology, operating room nursing, laboratory sciences, medical emergency, and anesthesia. The DREEM questionnaire was used as a standard tool. Data were analyzed using SPSS (v17) software. Student’s t-tests and analysis of variance (ANOVA) statistical tests were used. Results The mean of the achieved scores in the five domains was 113.5 out of 200 (56.74%), which was considered to be more positive than negative. The total mean scores for perception of learning, teaching, and atmosphere were 27.4/48 (57.24%), 24.60/44 (55.91%), and 26.8/48 (55.89%), respectively. Academic and social self-perceptions were 20.5/32 (64.11%) and 15.7/28 (56.36%), respectively. The total DREEM scores varied significantly between courses (P<0.01). The total scores of the students of operating room nursing, anesthesia, and laboratory sciences, first year students, and females were significantly higher than the other students (P<0.01). Conclusion The results have suggested that the students of medical sciences courses at RUMS generally hold positive perceptions toward their course environment. The differences between courses and their study pathway should be further investigated by analysis of specific items. Our results showed that it is essential for faculty members and course managers to make more efforts toward observing principles of instructional designs, to create an appropriate educational environment, and to reduce deficits in order to provide a better learning environment with more facilities

    Objective. To measure the impact of medication therapy management (MTM) learning activities on students’ confidence and intention to provide MTM using the Theory of Planned Behavior. Design. An MTM curriculum combining lecture instruction and active-learning strategies was incorporated into a required pharmacotherapy laboratory course. Assessment. A validated survey instrument was developed to evaluate student confidence and intent to engage in MTM services using the domains comprising the Theory of Planned Behavior. Confidence scores improved significantly from baseline for all items (p < 0.00), including identification of billable services, documentation, and electronic billing. Mean scores improved significantly for all Theory of Planned Behavior items within the constructs of perceived behavioral control and subjective norms (p < 0.05). At baseline, 42% of students agreed or strongly agreed that they had knowledge and skills to provide MTM. This percentage increased to 82% following completion of the laboratory activities. Conclusion. Implementation of simulated MTM activities in a pharmacotherapy laboratory significantly increased knowledge scores, confidence measures, and scores on Theory of Planned Behavior constructs related to perceived behavioral control and subjective norms. Despite these improvements, intention to engage in future MTM services remained unchanged. PMID:21829269

    We present collaborative work on a generic, modular infrastructure for virtual laboratories (VLs, similar to science gateways) that combine online access to data, scientific code, and computing resources as services that support multiple data intensive scientific computing needs across a wide range of science disciplines. We are leveraging access to 10+ PB of earth science data on Lustre filesystems at Australia's National Computational Infrastructure (NCI) Research Data Storage Infrastructure (RDSI) node, co-located with NCI's 1.2 PFlop Raijin supercomputer and a 3000 CPU core research cloud. The development, maintenance and sustainability of VLs is best accomplished through modularisation and standardisation of interfaces between components. Our approach has been to break up tightly-coupled, specialised application packages into modules, with identified best techniques and algorithms repackaged either as data services or scientific tools that are accessible across domains. The data services can be used to manipulate, visualise and transform multiple data types whilst the scientific tools can be used in concert with multiple scientific codes. We are currently designing a scalable generic infrastructure that will handle scientific code as modularised services and thereby enable the rapid/easy deployment of new codes or versions of codes. The goal is to build open source libraries/collections of scientific tools, scripts and modelling codes that can be combined in specially designed deployments. Additional services in development include: provenance, publication of results, monitoring, workflow tools, etc. The generic VL infrastructure will be hosted at NCI, but can access alternative computing infrastructures (i.e., public/private cloud, HPC).The Virtual Geophysics Laboratory (VGL) was developed as a pilot project to demonstrate the underlying technology. This base is now being redesigned and generalised to develop a Virtual Hazards Impact and Risk Laboratory

  18. Regulatory science based approach in development of novel medical devices.

    PubMed

    Sakuma, Ichiro

    2015-08-01

    For development rational evaluation method for medical devices' safety and efficacy, regulatory science studies are important. Studies on regulatory affairs related to a medical device under development should be conducted as well as its technological development. Clinical performance of a medical device is influenced by performance of the device, medical doctors' skill, pathological condition of a patient, and so on. Thus it is sometimes difficult to demonstrate superiority of the device in terms of clinical outcome although its efficacy as a medical device is accepted. Setting of appropriate end points is required to evaluate a medical device appropriately. Risk assessment and risk management are the basis of medical device safety assurance. In case of medical device software, there are difficulties in identifying the risk due to its complexity of user environment and different design and manufacturing procedure compared with conventional hardware based medical devices. Recent technological advancement such as information and communication technologies (ICT) for medical devices and wireless network has raised new issue on risk management: cybersecurity. We have to watch closely the progress of safety standard development. PMID:26736611

    Privacy laws are intended to preserve human well-being and improve medical outcomes. We used the Sportstats website, a repository of competitive athletic data, to test how easily these laws can be circumvented. We designed a haphazard, unrepresentative case-series analysis and applied unscientific methods based on an Internet connection and idle time. We found it both feasible and titillating to breach anonymity, stockpile personal information and generate misquotations. We extended our methods to snoop on celebrities, link to outside databases and uncover refusal to participate. Throughout our study, we evaded capture and public humiliation despite violating these 6 privacy fundamentals. We suggest that the legitimate principle of safeguarding personal privacy is undermined by the natural human tendency toward showing off. PMID:18056619

    Abstracts and indexes constitute the most popular means of assuring adequate retrieval of the many thousands of papers published every year in the ever expanding field of medicine. Different types of abstracts and indexes are available for different purposes and to meet varying user requirements. The problem of "keeping up" with developments in one's own field of endeavour can usually be solved by qualified abstractors. Most indexes serve the purpose of assuring the retrieval of pertinent documents. However, in order to retrieve specific pieces of information which are absolutely indispensible to the medical practitioner or scientist, a new approach is needed. This technique, which is termed the "combined index-abstract" method, has been employed successfully for the handling of a large body of specific items of information in a restricted area of experimental and clinical pharmacology.

    Background: Ergonomics awareness helps in its right application and contributes significantly to general wellbeing and safety of worker at workplace. Aim: This cross-sectional descriptive study aimed at assessing the level of awareness and knowledge of the science of ergonomics among Medical Laboratory Scientists in Benin City, Nigeria. Subjects and Methods: A total of 106 medical laboratory scientists comprising 64 and 42 in public and private laboratories, respectively, were recruited for this study using systematic random sampling technique. Data were obtained from the study participants using a questionnaire and subsequently analyzed with the statistical software INSTAT®. Results: Out of 106 study participants, 27 (25.5%) were reported to have heard of the term ergonomics. Awareness was significantly associated with gender (male vs. female: 38.5% [15/39] vs. 17.9% [12/67]; odds ratio = 2.9; 95% confidence interval = 1.2, 7.1;P = 0.02). Awareness of ergonomics was not significantly affected by affiliation (P = 0.18), area of specialization (P = 0.78), post-qualification experience (P = 0.43), and educational qualification (P = 0.23) of the study participants. Irrespective of the affiliation of the participant, only 6 of 27 (22.2%) participants who were aware of ergonomics knew at least a benefit of right application of ergonomics in the laboratory. Knowledge of risk factors for the development of musculoskeletal disorders was reported by 8 of 27 (29.6%) persons who claimed to be aware of ergonomics. Conclusions: Awareness of ergonomics and knowledge of gains of its right application was poor among the study participants. Regular ergonomic education of medical laboratory scientists in Nigeria is advocated. PMID:27057381

  4. Synchrotron radiation applications in medical research at Brookhaven National Laboratory

    SciTech Connect

    Thomlinson, W.

    1997-08-01

    In the relatively short time that synchrotrons have been available to the scientific community, their characteristic beams of UV and X-ray radiation have been applied to virtually all areas of medical science which use ionizing radiation. The ability to tune intense monochromatic beams over wide energy ranges clearly differentiates these sources from standard clinical and research tools. The tunable spectrum, high intrinsic collimation of the beams, polarization and intensity of the beams make possible in-vitro and in-vivo research and therapeutic programs not otherwise possible. From the beginning of research operation at the National Synchrotron Light Source (NSLS), many programs have been carrying out basic biomedical research. At first, the research was limited to in-vitro programs such as the x-ray microscope, circular dichroism, XAFS, protein crystallography, micro-tomography and fluorescence analysis. Later, as the coronary angiography program made plans to move its experimental phase from SSRL to the NSLS, it became clear that other in-vivo projects could also be carried out at the synchrotron. The development of SMERF (Synchrotron Medical Research Facility) on beamline X17 became the home not only for angiography but also for the MECT (Multiple Energy Computed Tomography) project for cerebral and vascular imaging. The high energy spectrum on X17 is necessary for the MRT (Microplanar Radiation Therapy) experiments. Experience with these programs and the existence of the Medical Programs Group at the NSLS led to the development of a program in synchrotron based mammography. A recent adaptation of the angiography hardware has made it possible to image human lungs (bronchography). Fig. 1 schematically depicts the broad range of active programs at the NSLS.

    In late 1994, Sandia National Laboratories in Albuquerque, New Mexico, (SNL/NM), was instructed by the Department of Energy (DOE) Isotope Production and Distribution Program (IPDP) to examine the feasibility of producing medically useful radioisotopes using the Annular Core Research Reactor (ACRR) and the Hot Cell Facility (HCF). Los Alamos National Laboratory (LANL) would be expected to supply the targets to be irradiated in the ACRR. The intent of DOE would be to provide a capability to satisfy the North American health care system demand for {sup 99}Mo, the parent of {sup 99m}Tc, in the event of an interruption in the current Canadian supply. {sup 99m}Tc is used in 70 to 80% of all nuclear medicine procedures in the US. The goal of the SNL/NM study effort is to determine the physical plant capability, infrastructure, and staffing necessary to meet the North American need for {sup 99}Mo and to identify and examine all issues with potential for environmental impact.

  19. Artificial neural networks in laboratory medicine and medical outcome prediction.

    Tafeit, E; Reibnegger, G

    1999-09-01

    Since the early nineties the number of scientific papers reporting on artificial neural network (ANN) applications in medicine has been quickly increasing. In the present paper, we describe in some detail the architecture of network types used most frequently in ANN applications in the broad field of laboratory medicine and clinical chemistry, present a technique-structured review about the recent ANN applications in the field, and give information about the improvements of available ANN software packages. ANN applications are divided into two main classes: supervised and unsupervised methods. Most of the described supervised applications belong to the fields of medical diagnosis (n = 7) and outcome prediction (n = 9). Laboratory and clinical data are presented to multilayer feed-forward ANNs which are trained by the back propagation algorithm. Results are often better than those of traditional techniques such as linear discriminant analysis, classification and regression trees (CART), Cox regression analysis, logistic regression, clinical judgement or expert systems. Unsupervised ANN applications provide the ability of reducing the dimensionality of a dataset. Low-dimensional plots can be generated and visually understood and compared. Results are very similar to that of cluster analysis and factor analysis. The ability of Kohonen's self-organizing maps to generate 2D maps of molecule surface properties was successfully applied in drug design. PMID:10596951

    1995-09-01

    The Environmental Molecular Sciences Laboratory (EMSL) is currently under construction at Pacific Northwest Laboratory (PNL) for the U.S. Department of Energy (DOE). This laboratory will be used for molecular and environmental sciences research to identify comprehensive solutions to DOE`s environmental problems. Major facilities within the EMSL include the Molecular Sciences Computing Facility (MSCF), a laser-surface dynamics laboratory, a high-field nuclear magnetic resonance (NMR) laboratory, and a mass spectrometry laboratory. The EMSL is scheduled to open early in 1997 and will house about 260 resident and visiting scientists. It is anticipated that at least six (6) terabytes of data will be archived in the first year of operation. An object-oriented database management system (OODBMS) and a mass storage system will be integrated to provide an intelligent, automated mechanism to manage data. The resulting system, called the DataBase Computer System (DBCS), will provide total scientific data management capabilities to EMSL users. A prototype mass storage system based on the National Storage Laboratory`s (NSL) UniTree has been procured and is in limited use. This system consists of two independent hierarchies of storage devices. One hierarchy of lower capacity, slower speed devices provides support for smaller files transferred over the Fiber Distributed Data Interface (FDDI) network. Also part of the system is a second hierarchy of higher capacity, higher speed devices that will be used to support high performance clients (e.g., a large scale parallel processor). The ObjectStore OODBMS will be used to manage metadata for archived datasets, maintain relationships between archived datasets, and -hold small, duplicate subsets of archived datasets (i.e., derivative data). The interim system is called DBCS, Phase 0 (DBCS-0). The production system for the EMSL, DBCS Phase 1 (DBCS-1), will be procured and installed in the summer of 1996.

    The College of Medicine of the University of Ibadan recently revised its MBBS and BDS curricula to a competency-based medical education method of instruction. This paper reports the process of revising the methods of instruction and assessment in the core basic medical sciences directed at producing medical and dental graduates with a sound knowledge of the subjects sufficient for medical and dental practice and for future postgraduate efforts in the field or related disciplines. The health needs of the community and views of stakeholders in the Ibadan medical and dental schools were determined, and the "old" curriculum was reviewed. This process was directed at identifying the strengths and weaknesses of the old curricula and the newer competences required for modern-day medical/dental practice. The admission criteria and processes and the learning methods of the students were also studied. At the end of the review, an integrated, system-based, community-oriented, person-centered, and competency-driven curriculum was produced and approved for implementation. Four sets of students have been admitted into the curriculum. There have been challenges to the implementation process, but these have been overcome by continuous faculty development and reorientation programs for the nonteaching staff and students. Two sets of students have crossed over to the clinical school, and the consensus among the clinical teachers is that their knowledge and application of the basic medical sciences are satisfactory. The Ibadan medical and dental schools are implementing their competency-based medical education curricula successfully. The modifications to the teaching and assessment of the core basic medical science subjects have resulted in improved learning and performance at the final examinations. PMID:27486351

    1994-06-01

    A lunar life sciences laboratory would be an ideal learning center to develop science capabilities to extend humans to Mars. It could be initiated without a large amount of preparatory human research due to previous lunar experience, short flight time (3 days), and the ability to gather 'real time' life sciences data. Human studies can go beyond previous zero-g research providing information on lunar 1/6 gravity effects (an early data point in determining whether long-term fractional gravity can assist in maintaining health and performance) and insight into whether a Mars transfer vehicle should be designed for artificial-g (and, if so, whether fractional-g might be adequate). Insights into human behavior/performance can also be gained. A lunar biological laboratory could provide a means of conducting long-duration experiments on the biological effects of radiation and fractional gravity (in animals and plants).

    Introduction: The need for medical students to be computer literate is vital. With the rapid integration of information technology (IT) in the health care field, equipping students of medical universities withcomputer competencies to effectively use are needed. The purpose of this study was to assess computer literacy (CL) needs of medical sciences students. Methods: This is descriptive-analytic. The population of the study comprised all students at Zahedan University of Medical Sciences. 385 students from allschools (Medicine, dentistry, paramedics, health, rehabilitation, nursing and midwifery) were selected through randomized- classified sampling. For data collecting, the Lin Tung- Cheng questionnaire was used which it contained 24 items in six sections. The obtained data analyzed by SPSS 15. Results: The results showed that the 77.1% had personal computer. The total mean of students’ computer literacy around six domains was 141.9±49.5 out of 240. The most familiarity with computers was the ability to it in internet (29.0±11.4) and the lowest was familiarity and using ability of hard ware (17.5±10.6). There was a significant relationship between passing the Computer lesson (P=0.001), passing Computer course (P=0.05) and having personal computer (P=0.001) with the mean of computer literacy. Discussion: In sum, the medical sciences students’ familiarity with computer literacy was not satisfactory and they had not appropriate familiarity with computer literacy skills. The researchers suggest the officials and in-charges to plan educational program for improving computer literacy skills in medical sciences students. PMID:25946919

    This study examined ways of promoting research in the medical sciences by evaluating trends in research funding, and the present status of research funding by the Korea Science and Engineering Foundation (KOSEF). This study analyzed statistics from KOSEF from 1978 to 2003 to examine support for research. In medical science field, group-based programs receive more funding than do individual-based programs. The proportion of research funds allocated to the medical sciences has increased markedly each year. Researchers in the medical sciences have submitted more articles to Science Citation Index (SCI) journals than to non-SCI journals, relative to other fields. Researchers supported by the Mission-Oriented Basic Grants program have published the majority of these papers, followed by those supported by the Programs for Leading Scientists, Regional Scientists, Leading Women Scientists, Young Scientists, and Promising Women Scientists, in that order. Funding by KOSEF reflects many decades of government support for research and development, the development and maintenance of necessary infrastructure, and the education and training of medical scientists.

    PubMed

    Sismondo, Sergio

    2009-04-01

    Publication of pharmaceutical company-sponsored research in medical journals, and its presentation at conferences and meetings, is mostly governed by 'publication plans' that extract the maximum amount of scientific and commercial value out of data and analyses through carefully constructed and placed papers. Clinical research is typically performed by contract research organizations, analyzed by company statisticians, written up by independent medical writers, approved and edited by academic researchers who then serve as authors, and the whole process organized and shepherded through to journal publication by publication planners. This paper reports on a conference of an international association of publication planners. It describes and analyzes their work in an ecological framework that relates it to marketing departments of pharmaceutical companies, medical journals and publishers, academic authors, and potential audiences. The medical research described here forms a new kind of corporate science, designed to look like traditional academic work, but performed largely to market products. PMID:19831220

    2013-06-01

    Teaching science to secondary students in an online environment is a growing international trend. Despite this trend, reports of empirical studies of this phenomenon are noticeably missing. With a survey concerning the nature of laboratory activities, this study describes the perspective of 35-secondary teachers from 15-different U.S. states who are teaching science online. The type and frequency of reported laboratory activities are consistent with the tradition of face-to-face instruction, using hands-on and simulated experiments. While provided examples were student-centered and required the collection of data, they failed to illustrate key components of the nature of science. The features of student-teacher interactions, student engagement, and nonverbal communications were found to be lacking and likely constitute barriers to the enactment of inquiry. These results serve as a call for research and development focused on using existing communication tools to better align with the activity of science such that the nature of science is more clearly addressed, the work of students becomes more collaborative and authentic, and the formative elements of a scientific inquiry are more accessible to all participants.

    The CHAOS and Thermal Sciences Laboratory (CaTs) at James Madison University evolved into a noteworthy effort to increase minority representation in the sciences and mathematics. Serving ten students and faculty directly, and nearly 50 students indirectly, CaTs, through recruitment efforts, workshops, mentoring programs, tutorial services and research and computational laboratories, fulfilled its intent to initiate an academically enriched research program aimed at strengthening the academic and self-actualization skills of undergraduate students with potential to pursue doctoral study in the sciences. The stated goal of the program was to increase by 5% the number of enrolled mathematics and science students into the program. Success far exceeded the program goals by producing 100% graduation rate of all supported recipients during its tenure, with 30% of the students subsequently in pursuit of graduate degrees. Student retention in the program exceeded 90% and faculty participation exceeded the three members involved in mentoring and tutoring, gaining multi-disciplinary support. Aggressive marketing of the program resulted in several paid summer internships and commitments from NASA and an ongoing relationship with CHROME, a nationally recognized organization which focuses on developing minority students in the sciences and mathematics. Success of the program was only limited by the limited fiscal resources at NASA which resulted in phasing out of the program.

    A narrowband digital speech communication test facility has been established and operates between Lincoln Laboratory and the Wright-Patterson Aerospace Medical Research Laboratory. Noise fields simulating the acoustic environments of E3A and F-15 aircraft are established and Air Force personnel use the link operating at 2400 bps with a vocoder designed at Lincoln Laboratory, and a commercial telephone line modem. The facility includes a digital signal processing computer which can introduce bit errors and delay into the transmit and receive data. Communication scenarios are used to exercise the vocoder-modem channel with the dynamics and vocabulary of typical operational exchanges. Answers to a standard questionnaire provide acceptability data for the 2400 bps JTIDS class 2 voice channel. For the tests run so far, the 2400 bps voice is acceptable in the sense of positive user response to the questionnaire. Further testing using error and delay simulations will follow. An F-15 to F-15 link will be simulated at AMRL using a pair of vocoders operating back-to-back and in separate noise chambers.

    Information science is changing from an applied service-oriented activity to a basic research discipline. The library profession must earn a central place in this endeavor, and must address a number of important issues. These include ownership and intellectual property rights, a stronger research component for the profession, development of quality assurance systems for health information services, and a conceptual framework for training and career development of health sciences library technicians. The future of medical librarianship as a profession depends on a lasting commitment to research, a clear vision of the profession's fundamental mission and of the library's place in society.

    The class character of medicine is most easily discerned in the inequitable organization of health services. Capital's shaping of the patterns of disease and our medical/scientific responses is less apparent but equally strong. We illustrate this point by reviewing some recent history of cardiovascular diseases and therapies. Hitherto unknown afflictions have become commonplace. Our diagnostic and therapeutic concepts are the crystallization of a long history of scientific effort--an effort dominated and directed by capitalist imperatives. The work of the clinician rests on this scientific substrate, and recognition or rejection of its class nature provides a potential basis for a new medical science but not the needed results. The socialist transformation of medicine will require a recognition of the capitalist specificity of current science, and the painstaking construction of alternative modes of thought. PMID:2660277

These definitions provide a formal representation of what biomarkers are in a way that allows us to remove certain ambiguities and inconsistencies in the documentation provided by the IOM.

    The Mars Science Laboratory Robotic Arm (RA) is a key component for achieving the primary scientific goals of the mission. The RA supports sample acquisition by precisely positioning a scoop above loose regolith or accurately preloading a percussive drill on Martian rocks or rover-mounted organic check materials. It assists sample processing by orienting a sample processing unit called CHIMRA through a series of gravity-relative orientations and sample delivery by positioning the sample portion door above an instrument inlet or the observation tray. In addition the RA facilitates contact science by accurately positioning the dust removal tool, Alpha Particle X-Ray Spectrometer (APXS) and the Mars Hand Lens Imager (MAHLI) relative to surface targets. In order to fulfill these seemingly disparate science objectives the RA must satisfy a variety of accuracy and performance requirements. This paper describes the necessary arm requirement specification and the test campaign to demonstrate these requirements were satisfied.

  7. Medical student perceptions of a behavioural and social science curriculum

    PubMed Central

    2011-01-01

    Background In 2006, Oregon Health & Science University began implementing changes to better integrate mental health and social science into the curriculum by addressing the Institute of Medicine's (IOM's) 2004 recommendation for the inclusion of six behavioural and social science (BSS) domains: health policy and economics, patient behaviour, physician–patient interaction, mind–body interactions, physician role and behaviour, and social and cultural issues. Methods We conducted three focus groups with a purposive sample of 23 fourth-year medical students who were exposed to 4 years of the new curriculum. Students were asked to reflect upon the adequacy of their BSS training specifically as it related to the six IOM domains. The 90-minute focus groups were recorded, transcribed and analysed. Results Students felt the MS1 and MS2 years of the curriculum presented a strong didactic orientation to behavioural and social science precepts. However, they reported that these principles were not well integrated into clinical care during the second two years. Students identified three opportunities to further the inclusion of BSS in their clinical training: presentation of BSS concepts prior to relevant clinical exposure, consistent BSS skills mentoring in the clinical setting, and improving cultural congruence between aspects of BSS and biomedicine. Conclusions Students exposed to the revised BSS curriculum tend to value its principles; however, modelling and practical training in the application of these principles during the second two years of medical school are needed to reinforce this learning and demonstrate methods of integrating BSS principles into practice.

    2013-01-01

    Nowadays, educators pay attention to emotional intelligence which is defined as the ability to monitor and explain one's own and other's emotional experience and feelings to differentiate between them as well as applying necessary information for determining thoughts and actions. The goal of this study was to determine emotional intelligence of medical residents of Tehran University of Medical Sciences. By means of two stage cluster sampling, 98 medical residents of Tehran University of Medical Sciences were selected. Participants were asked to fill valid and reliable Persian version of Emotional Quotient inventory (EQ-i) questionnaire which had been developed due to Bar-On model. Seventy two filled-up questionnaires were returned (RR=73%). Mean EI score of all participants was 319.94 ± 32.4. Mean EI score was not significantly different between male and female also, single and married participants. EI did not differ significantly in residents in respect to their discipline. Mean responsibility subscale differ significantly between male and female participants (P=0.008). Multiple regression analysis showed that happiness subscale is a predictive factor for total EI score (B=-0.32, P=0.009). Responsibility subscale differed significantly between men and women participants and happiness subscale was a good predictor for emotional intelligence score. These factors should be considered in education of medical residents. PMID:23605604

    Background Derived from multiple disciplines and established in industries outside of medicine, Implementation Science (IS) seeks to move evidence-based approaches into widespread use to enable improved outcomes to be realized as quickly as possible by as many as possible. Methods This review highlights selected IS theories and models, chosen based on the experience of the authors, that could be used to plan and deliver medical education activities to help learners better implement and sustain new knowledge and skills in their work settings. Results IS models, theories and approaches can help medical educators promote and determine their success in achieving desired learner outcomes. We discuss the importance of incorporating IS into the training of individuals, teams, and organizations, and employing IS across the medical education continuum. Challenges and specific strategies for the application of IS in educational settings are also discussed. Conclusions Utilizing IS in medical education can help us better achieve changes in competence, performance, and patient outcomes. IS should be incorporated into curricula across disciplines and across the continuum of medical education to facilitate implementation of learning. Educators should start by selecting, applying, and evaluating the teaching and patient care impact one or two IS strategies in their work. PMID:25911282

    Carpenter, John

    2014-06-03

    Jack Carpenter, pioneer of accelerator-based pulsed spallation neutron sources, talks about neutron science at Oak Ridge National Laboratory (ORNL) and a need for a second target station at the Spallation Neutron Source (SNS). ORNL is the Department of Energy's largest multiprogram science and energy laboratory, and is home to two scientific user facilities serving the neutron science research community: the High Flux Isotope Reactor (HFIR) and SNS. HFIR and SNS provide researchers with unmatched capabilities for understanding the structure and properties of materials, macromolecular and biological systems, and the fundamental physics of the neutron. Neutrons provide a window through which to view materials at a microscopic level that allow researchers to develop better materials and better products. Neutrons enable us to understand materials we use in everyday life. Carpenter explains the need for another station to produce long wavelength neutrons, or cold neutrons, to answer questions that are addressed only with cold neutrons. The second target station is optimized for that purpose. Modern technology depends more and more upon intimate atomic knowledge of materials, and neutrons are an ideal probe.

  17. [Cardiology was born with the modern medical science].

    PubMed

    de Micheli, Alfredo

    2015-01-01

    Modern medical science was born in the post-Renaissance age and began to consolidate towards the middle of the XVII century thanks to physicists, physiologists and biologists, most of whom were direct or indirect pupils of Galileo. The discovery of blood circulation by Harvey is now considered the only progress in physiology at the beginning of the XVII century, comparable to the current advances seen in physical sciences. The history of this exploit could be written from view point of the progressive advance in knowledge. In his experiments, Harvey referred to the authentic not imaginary experiments, and put forward irrefutable quantitative arguments. We can therefore claim that his discovery of blood circulation was the first proper explanation of an organic process and the starting point leading to experimental physiology. So it seems justified to assert that modern medical science did not all rise suddenly, but was gradually structured starting from the middle of the XVII century following the path traced by William Harvey in light of Galileo's thought.

Today, there is tension between the time needed to teach an ever-expanding knowledge base in science and the time needed for increased instruction in clinical application and in the behavioral, ethical, and managerial knowledge and skills needed to prepare for clinical experiences. One result has been at least a perceived reduction in time and focus on the foundational sciences. In this context, the International Association of Medical Science Educators initiated a study to address the role and value of the basic sciences in medical education by seeking perspectives from various groups of medical educators to five questions: (1) What are the sciences that constitute the foundation for medical practice? (2) What is the value and role of the foundational sciences in medical education? (3) When and how should these foundational sciences be incorporated into the medical education curriculum? (4) What sciences should be prerequisite to entering the undergraduate medical curriculum? (5) What are examples of the best practices for incorporating the foundational sciences into the medical education curriculum? The results suggest a broad group of experts believes that an understanding of basic science content remains essential to clinical practice and that teaching should be accomplished across the entire undergraduate medical education experience and integrated with clinical applications. Learning the sciences also plays a foundational role in developing discipline and rigor in learners' thinking skills, including logical reasoning, critical appraisal, problem solving, decision making, and creativity.

    The dedication of the new Environmental Sciences Laboratory coincided with the 25th year of the establishment of the science of ecology at Oak Ridge National Laboratory. That quarter century witnessed the evolution of ecology from an obscure, backwater discipline of biology to a broadly used, everyday household word. The transition reflected broad and basic changes in our social and cultural view of the world. This was brought about as a result of the awareness developed in our society of the importance of the environment, coupled with efforts of ecologists and other environmental scientists who identified, clarified, and formulated the issues and challenges of environmental protection for both the lay public and the scientific community. In many respects, the activities in ecology at ORNL were a microcosm of the broader social scene; the particular problems of the environment associated with atomic energy needed to be defined in scientific terms and articulated in both the specific and general sense for a larger audience which was unfamiliar with the field and somewhat alien to its concepts and philosophy. The success of this effort is reflected in the existence of the new Environmental Sciences Laboratory. This dedication volume brings together the thoughts and reflections of many of these scientists whose efforts contributed in a unique and individualistic fashion not only to ORNL but also to the national identification of ecology and its importance to the achievement of our national goals. Their remarks and presentations are not only a pleasant and personally gratifying recapitulation of the past and of ORNL's contributions to ecology but also portend some of the challenges to ecology in the future.

  5. Bridle Device in Mars Science Laboratory Descent Stage

    2008-01-01

    This view of a portion of the descent stage of NASA's Mars Science Laboratory shows two of the stage's three spherical fuel tanks flanking the bridle device assembly. The photograph was taken in early October 2008 from the center of the descent stage looking outward. The top of the descent stage is toward the top of the image.

    The bridle device assembly is about two-thirds of a meter, or 2 feet, from top to bottom, and has two main parts. The cylinder on the top is the descent brake. The conical-shaped mechanism below that is the bridle assembly, including a spool of nylon and Vectran cords that will be attached to the rover.

    When pyrotechnic bolts fire to sever the rigid connection between the rover and the descent stage, gravity will pull the tethered rover away from the descent stage. The bridle or tether, attached to three points on the rover, will unspool from the bridle assembly, beginning from the larger-diameter portion. The rotation rate of the assembly, hence the descent rate of the rover, will be governed by the descent brake. Inside the housing of that brake are gear boxes and banks of mechanical resistors engineered to prevent the bridle from spooling out too quickly or too slowly. The length of the bridle will allow the rover to be lowered about 7.5 meters (25 feet) while still tethered to the descent stage.

    The Starsys division of SpaceDev Inc., Poway, Calif., provided the descent brake. NASA's Jet Propulsion Laboratory, Pasadena, Calif., built the bridle assembly. Vectran is a product of Kuraray Co. Ltd., Tokyo. JPL, a division of the California Institute of Technology, manages the Mars Science Laboratory Project for the NASA Science Mission Directorate, Washington.

    This is hardware for controlling the final lowering of NASA's Mars Science Laboratory rover to the surface of Mars from the spacecraft's hovering, rocket-powered descent stage.

    The photo shows the bridle device assembly, which is about two-thirds of a meter, or 2 feet, from end to end, and has two main parts. The cylinder on the left is the descent brake. On the right is the bridle assembly, including a spool of nylon and Vectran cords that will be attached to the rover.

    When pyrotechnic bolts fire to sever the rigid connection between the rover and the descent stage, gravity will pull the tethered rover away from the descent stage. The bridle or tether, attached to three points on the rover, will unspool from the bridle assembly, beginning from the larger-diameter portion of the spool at far right. The rotation rate of the assembly, hence the descent rate of the rover, will be governed by the descent brake.

    The NASA Mars Science Laboratory (MSL) and its Curiosity Rover, a part of NASA's Mars Exploration Program, represent the most ambitious undertaking to date to explore the red planet. MSL/Curiosity was designed primarily to determine whether Mars ever had an environment capable of supporting microbial life. NASA's MSL education program was designed to take advantage of existing, highly successful event based education programs to communicate Mars science and education themes to worldwide audiences through live webcasts, video interviews with scientists, TV broadcasts, professional development for teachers, and the latest social media frameworks. We report here on the success of the MSL education program and discuss how this methodological framework can be used to enhance other event based education programs.

    The US National Science Foundation and the US underground science community are well into the campaign to establish a world-class, multi-disciplinary deep underground science and engineering laboratory — DUSEL. The NSF's review committee, following the first two NSF solicitations, selected Homestake as the prime site to be developed into an international, multidisciplinary, world-class research facility. Homestake DUSEL will provide much needed underground research space to help relieve the worldwide shortage, particularly at great depth, and will develop research campuses at different depths to satisfy the research requirements for the coming decades. The State of South Dakota has demonstrated remarkable support for the project and has secured the site with the transfer of the former Homestake Gold Mine and has initiated re-entry and rehabilitation of the facility to host a modest interim science program with state funds and those from a substantial philanthropic donor. I review the scientific case for DUSEL and the progress in developing the preliminary design of DUSEL in Homestake and the initial suite of experiments to be funded along with the facility.

    The National Science Foundation and the international underground science community are well into establishing a world-class, multidisciplinary Deep Underground Science and Engineering Laboratory (DUSEL) at the former Homestake mine in Lead South Dakota. The NSF's review committee, following the first two NSF solicitations, selected the Homestake Proposal and site as the prime location to be developed into an international research facility. Homestake DUSEL will provide much needed underground research space to help relieve the worldwide shortage, particularly at great depth, and will develop research campuses at several different depths to satisfy the research requirements for the coming decades. The State of South Dakota has demonstrated remarkable support for the project and has secured the site with the transfer from the Homestake Mining Corp. The State, through its Science and Technology Authority with state funds and those of a philanthropic donor has initiated rehabilitation of the surface and underground infrastructure including the Ross and Yates hoists accessing the 4850 Level (feet below ground, 4100 to 4200 mwe). The scientific case for DUSEL and the progress in establishing the preliminary design of the facility and the associated suite of experiments to be funded along with the facility by the NSF are presented.

    The Science on Saturday Program at Princeton Plasma Physics Laboratory consists of a series of Saturday morning lectures on various topics in science by scientists, engineers, educators, and others with an interesting story. This program has been in existence for over twelve years and has been advertised to and primarily aimed at the high school level. Topics ranging from superconductivity to computer animation and gorilla conservation to pharmaceutical design have been covered. Lecturers from the staff of Princeton, Rutgers, AT and T, Bristol Meyers Squibb, and many others have participated. Speakers have ranged from Nobel prize winners, astronauts, industrialists, educators, engineers, and science writers. Typically, there are eight to ten lectures starting in January. A mailing list has been compiled for schools, science teachers, libraries, and museums in the Princeton area. For the past two years AT and T has sponsored buses for Trenton area students to come to these lectures and an effort has been made to publicize the program to these students. The series has been very popular, frequently overfilling the 300 seat PPPL auditorium. As a result, the lectures are videotaped and broadcast to a large screen TV for remote viewing. Lecturers are encouraged to interact with the audience and ample time is provided for questions.

    2013-01-01

    The Mars Science Laboratory (MSL) spacecraft had ambitious navigation delivery and knowledge accuracy requirements for landing inside Gale Crater. Confidence in the orbit determination (OD) solutions was increased by investigating numerous filter strategies for solving the orbit determination problem. We will discuss the strategy for the different types of variations: for example, data types, data weights, solar pressure model covariance, and estimating versus considering model parameters. This process generated a set of plausible OD solutions that were compared to the baseline OD strategy. Even implausible or unrealistic results were helpful in isolating sensitivities in the OD solutions to certain model parameterizations or data types.

    The NASA/JPL Mars Science Laboratory (MSL) spacecraft mass properties were measured on a spin balance table prior to launch. This paper discusses the requirements and issues encountered with the setup, qualification, and testing using the spin balance table, and the idiosyncrasies encountered with the test system. The final mass measurements were made in the Payload Hazardous Servicing Facility (PHSF) at Kennedy Space Center on the fully assembled and fueled spacecraft. This set of environmental tests required that the control system for the spin balance machine be at a remote location, which posed additional challenges to the operation of the machine

    2007-01-01

    This paper describes the preliminary concept for the RCS 3-axis attitude controller for the exo-atmospheric and guided entry phases of the Mars Science Laboratory Entry, Descend and Landing. The entry controller is formulated as three independent channels in the control frame, which is nominally aligned with the stability frame. Each channel has a feedfoward and a feedback. The feedforward path enables fast response to large bank commands. The feedback path stabilizes the vehicle angle of attack and sideslip around its trim position, and tracks bank commands. The feedback path has a PD/D structure with deadbands that minimizes fuel usage. The performance of this design is demonstrated via simulation.

    1994-10-01

    Changes in laboratory animal science in the 20 years since George Porter's death are reviewed, with particular emphasis on animal welfare. The need for a generally acceptable definition of animal welfare is emphasized and a new definition is propounded. The concept of stewardship as a basis for human-animal relationships is explored. This involves Man accepting his responsibility for his relationship with, and care of, animals while simultaneously accepting a moral responsibility to God, or others, for that care and relationship.

    Purpose: Interprofessional collaboration (IPC) and interprofessional education (IPE) are increasingly emphasized in the education of health professions. Xavier University School of Medicine, a Caribbean medical school admits students from the United States, Canada, and other countries to the undergraduate medical course. The present study was carried out to obtain information about the attitude toward IPC among basic science medical students and note differences, if any, among different subgroups. Methods: The study was conducted among first to fifth semester students during July 2015 using the previously validated Jefferson Scale of Attitudes Toward Interprofessional Collaboration (JeffSATIC). Gender, age, semester, and nationality were noted. Participants’ agreement with a set of 20 statements was studied. Mean total scores, working relationship, and accountability scores were calculated and compared among different subgroups of respondents (p<0.05). Results: Sixty-seven of the 71 students (94.4%) participated. Cronbach’s alpha value of the questionnaire was 0.827, indicating good internal consistency. The mean total score was 104.48 (maximum score 140) while the working relationship and accountability scores were 63.51 (maximum score 84) and 40.97 (maximum score 56), respectively. Total scores were significantly higher among third-semester students and students of Canadian nationality. Working relationship and accountability scores were higher among first and third-semester students. Conclusion: The total working relationship and accountability scores were lower compared to those obtained in a previous study. Opportunities for IPE and IPC during the basic science years should be strengthened. Longitudinal studies in the institution may be helpful. Similar studies in other Caribbean medical schools are required. PMID:26543691

  17. Autonomy and Privacy in Clinical Laboratory Science Policy and Practice.

    2014-01-01

    Rapid advancements in diagnostic technologies coupled with growth in testing options and choices mandate the development of evidence-based testing algorithms linked to the care paths of the major chronic diseases and health challenges encountered most frequently. As care paths are evaluated, patient/consumers become partners in healthcare delivery. Clinical laboratory scientists find themselves firmly embedded in both quality improvement and clinical research with an urgent need to translate clinical laboratory information into knowledge required by practitioners and patient/consumers alike. To implement this patient-centered care approach in clinical laboratory science, practitioners must understand their roles in (1) protecting patient/consumer autonomy in the healthcare informed consent process and (2) assuring patient/consumer privacy and confidentiality while blending quality improvement study findings with protected health information. A literature review, describing the current ethical environment, supports a consultative role for clinical laboratory scientists in the clinical decision-making process and suggests guidance for policy and practice regarding the principle of autonomy and its associated operational characteristics: informed consent and privacy.

    Physicians in every medical and surgical field must be able to use pathology concepts and skills in their practice: for example, they must order and interpret the correct laboratory tests, they must use their understanding of pathogenesis to diagnose and treat, and they must work with the laboratory to care for their patients. These important concepts and skills may be ignored by medical schools and even national/international organizations setting graduation expectations for medical students. There is an evolving international consensus about the importance of exit competencies for medical school graduates, which define the measurable or observable behaviors each graduate must be able to demonstrate. The Canadian Association of Pathologists (CAP) Education Group set out to establish the basic competencies in pathology and laboratory medicine which should be expected of every medical graduate: not competencies for pathologists, but for medical graduates who intend to enter any residency program. We defined 4 targets for pathology and laboratory medicine exit competencies: that they represent only measurable behaviors, that they be clinically focused, that they be generalizable to every medical graduate, and that the final competency document be user-friendly. A set of competencies was developed iteratively and underwent final revision at the 2012 CAP annual meeting. These competencies were subsequently endorsed by the CAP executive and the Canadian Leadership Council on Laboratory Medicine. This clinically focused consensus document provides the first comprehensive list of exit competencies in pathology and laboratory medicine for undergraduate medical education. PMID:25776028

    This study aims to investigate the quality of life (QOL) of Tehran University of Medical Sciences' (TUMS) medical students at different educational levels and specify the most important factors related to this quality. A sample of 242 medical students was selected randomly, given their number in three educational levels (basic sciences, physiopathology-stager and intern). The QOL was measured by WHOQOL-BREF. The students obtained average high score in two psychological and environmental health domains, and low score in physical health and social relationship domains. As the educational level of students increased their quality of life decreased at all four domains. At social relationship domain, the female students had overall better situation as compared to males (p=0.009). The female and male students had opposite condition at the level of basic sciences and internship, in a way that the female students earned higher marks at basic sciences level and the males at internship level (P= 0.008). The condition of female students in terms of environmental, physical and psychological health became static while their education rose. However, only environmental health of the male students reduced as their education level increased (P= 0.05). The students were of undesirable conditions in two domains of social relationship and physical health. Internship is a specific level in both groups which has a negative impact on the dimensions of quality of life and naturally needs more care for the students. Married status improved the students' QOL and could moderate the undesired effects of internship. PMID:24902021

    The selection of Gale crater as the Mars Science Laboratory landing site took over five years, involved broad participation of the science community via five open workshops, and narrowed an initial >50 sites (25 by 20 km) to four finalists (Eberswalde, Gale, Holden and Mawrth) based on science and safety. Engineering constraints important to the selection included: (1) latitude (±30°) for thermal management of the rover and instruments, (2) elevation (<-1 km) for sufficient atmosphere to slow the spacecraft, (3) relief of <100-130 m at baselines of 1-1000 m for control authority and sufficient fuel during powered descent, (4) slopes of <30° at baselines of 2-5 m for rover stability at touchdown, (5) moderate rock abundance to avoid impacting the belly pan during touchdown, and (6) a radar-reflective, load-bearing, and trafficable surface that is safe for landing and roving and not dominated by fine-grained dust. Science criteria important for the selection include the ability to assess past habitable environments, which include diversity, context, and biosignature (including organics) preservation. Sites were evaluated in detail using targeted data from instruments on all active orbiters, and especially Mars Reconnaissance Orbiter. All of the final four sites have layered sedimentary rocks with spectral evidence for phyllosilicates that clearly address the science objectives of the mission. Sophisticated entry, descent and landing simulations that include detailed information on all of the engineering constraints indicate all of the final four sites are safe for landing. Evaluation of the traversabilty of the landing sites and target "go to" areas outside of the ellipse using slope and material properties information indicates that all are trafficable and "go to" sites can be accessed within the lifetime of the mission. In the final selection, Gale crater was favored over Eberswalde based on its greater diversity and potential habitability.

    Since 1984, the Ford Motor Company Research Laboratory has offered a series of Saturday morning enrichment experiences and summer work opportunities for high school students and teachers. The goal is to increase awareness of technical careers and the importance of science and mathematics in industry. The Saturday sessions are run entirely by volunteers and are organized around current topics ranging from fundamental science (e.g., atmospheric chemistry) to advanced engineering and manufacturing (e.g., glass production). A typical session includes a lecture, laboratory tours and demonstrations, a refreshment/social break and a hands-on activity whenever possible. Over 500 students and teachers participate annually from over 120 area high schools. Nearly one third of the students are minorities from the city of Detroit. Session quality is monitored through feedback from participants and volunteers. Juniors and seniors who attend at least three sessions are eligible to compete for four-week summer internships. Typically, about twenty-five to thirty interns (out of forty to fifty applicants) are selected on the basis of a transcript, teacher recommendation and a 2500-word report on a technical topic. Ford also generally hosts about eight summer teacher fellows through a statewide program that began as an HSSTP initiative. The HSSTP was recently recognized by the industrial Research Institute as one of eleven {open_quotes}Winning [Pre-College Education] Programs{close_quotes} nationwide. Keys to success include strong grassroots and managerial support and extensive networking in the community.

    The most recent planetary science mission to Mars is Mars Science Laboratory (MSL) with the Curiosity rover, launched November 26, 2011 and landed at Gale Crater on August 6, 2012. This spacecraft was the first use at Mars of a complete closed-loop Guidance Navigation and Control (GN&C) system, including guided entry with a lifting body that greatly reduces dispersions during the Entry, Descent and Landing (EDL) phase to achieve a 25 km x 20 km landing error relative to the selected Gale Crater landing target. In order to confirm meeting the above landing criteria, high-fidelity simulation of the EDL phase is required. The tool used for 6DOF EDL trajectory verification analysis is Dynamics Simulator for Entry, Descent and Surface landing (DSENDS), which is a high-fidelity simulation tool from JPLs Dynamics and Real-Time Simulation Laboratory for the development, test and operations of aero-flight vehicles. DSENDS inherent capability is augmented for MSL with project-specific models of atmosphere, aerodynamics, sensors and thrusters along with GN&C flight software to enable high-fidelity trajectory simulation. This paper will present the model integration and independent verification experience of the JPL EDL trajectory analysis team.

    2004-11-01

    The National Academy of Science, as well as several long-range plans from the physics communities, have endorsed the need to create a large, multi-disciplinary underground laboratory in the US. Several potential sites have been identified, and the National Science Foundation has begun a solicitation process to help formulate the science program as well as to identify and develop candidate sites. The only site on the East Coast is at Kimballton, near Blacksburg, in western Virginia. Of all the sites, it is the only one located in sedimentary rocks. This makes it an IDEAL and unique location for both physics, geoscience, and engineering studies. Kimballton is also only half an hour from Virginia Tech, the largest university in the state of Virginia. A multi-institution group has been developing this possibility, and will be competing on the national scale to have DUSEL located at Kimballton. One of the assets of this location is a large limestone mine, already at a depth of 2300 ft (1850 mwe), with true drive-in access and extremely large caverns. The DUSEL facility at this location will try to take advantage of the existing infrastructure, while at the same time develop complementary and adjacent facilities down to 7000 ft (6000 mwe) to allow independent operation of the future facility. Since 2003, Virginia Tech and the Naval Research Laboratory have been working to also develop a general low-level facility at this location. The initial program is to help develop extremely low-background germanium and gas proportional counters, and a single super-module of the Low-Energy Neutrino Spectroscopy (LENS) detector -- designed to measure the real-time low-energy neutrino spectrum from the Sun, including the pp-flux. Progress in this program (including seismic imaging), and the proposed overall extensive science program (Phys, Geo, Eng, Bio) which can be addressed at Kimballton will be presented.

    The U.S. Department of Energy (DOE) provides technical support to the requesting federal agency such as the Federal Bureau of Investigation, Department of Defense, the National Space and Aeronautics and Space Administration (NASA), or a state agency to address the radiological consequences of an event. These activities include measures to alleviate damage, loss, hardship, or suffering caused by the incident; protect public health and safety; restore essential government services; and provide emergency assistance to those affected. Scheduled to launch in the fall of 2009, Mars Science Laboratory is part of NASA's Mars Exploration Program, a long-term effort of robotic exploration of the red planet. Mars Science Laboratory is a rover that will assess whether Mars ever was, or is still today, an environment able to support microbial life. In other words, its mission is to determine the planet's "habitability." The Mars Science Laboratory rover will carry a radioisotope power system that generates electricity from the heat of plutonium's radioactive decay. This power source gives the mission an operating lifespan on Mars' surface of a full Martian year (687 Earth days) or more, while also providing significantly greater mobility and operational flexibility, enhanced science payload capability, and exploration of a much larger range of latitudes and altitudes than was possible on previous missions to Mars. National Security Technologies, LLC (NSTec), based in Las Vegas, Nevada, will support the DOE in its role for managing the overall radiological contingency planning support effort. This paper will focus on new technologies that NSTec is developing to enhance the overall response capability that would be required for a highly unlikely anomaly. This paper presents recent advances in collecting and collating data transmitted from deployed teams and sensors. NSTec is responsible to prepare the contingency planning for a range of areas from monitoring and assessment

  12. [The Pangenetic theory in the tradition of Greek medical science].

    PubMed

    Imai, Masahiro

    2009-01-01

    The Pangenetic theory which holds that sperm comes from all the body seems to have been one of the most remarkable doctrines in Greek biology in the fifth and fourth centuries BC, since Aristotle gives a detailed description of the theory and criticizes it severely. The main sources of information about the Pangenetic theory are several medical treatises in the Hippocratic Corpus. There are only some mentions of it in the extant fragments ascribed to Democritus. It would be probable, therefore, that the theory had the origin of its theoretical form in the tradition of Greek medical science, and then came to the focus of attention among the Presocratic philosophers. Some scholars, on the other hand, claim that Democritus had a decisive role in the formation and development of the theory, which was then taken over by the Hippocratic doctors in their attempt to give a systematic explanation for some of the important genetic issues, such as the inheritance of similarities from parents to their children. It must be kept in mind, however, that Hippocratic doctors thought of particular fluids or humours with their inherent powers (delta upsilon nu alpha mu epsilon iotas) as the essential constituents of human body. This fact leads us to have an idea that the doctors had a completely different view of matter from the corpuscular theory, although Lesky (1950) and Lonie (1981) assume them to have been almost dependent on the atomism of Democritus. We can conclude that the Pangenetic theory came originally from Greek medical science, and then developed into the most influential doctrine before Aristotle. PMID:19824316

    This document was developed to provide the personnel working in the Environmental Sciences Division's Toxicology Laboratory with documented methods for conducting toxicity tests. The document consists of two parts. The first part includes the standard operating procedures (SOPs) that are used by the laboratory in conducting toxicity tests. The second part includes reference procedures from the US Environmental Protection Agency document entitled Short-Term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Freshwater Organisms, upon which the Toxicology Laboratory's SOPs are based. Five of the SOPs include procedures for preparing Ceriodaphnia survival and reproduction test. These SOPs include procedures for preparing Ceriodaphnia food (SOP-3), maintaining Ceriodaphnia cultures (SOP-4), conducting the toxicity test (SOP-13), analyzing the test data (SOP-13), and conducting a Ceriodaphnia reference test (SOP-15). Five additional SOPs relate specifically to the fathead minnow (Pimephales promelas) larval survival and growth test: methods for preparing fathead minnow larvae food (SOP-5), maintaining fathead minnow cultures (SOP-6), conducting the toxicity test (SOP-9), analyzing the test data (SOP-12), and conducting a fathead minnow reference test (DOP-14). The six remaining SOPs describe methods that are used with either or both tests: preparation of control/dilution water (SOP-1), washing of glassware (SOP-2), collection and handling of samples (SOP-7), preparation of samples (SOP-8), performance of chemical analyses (SOP-11), and data logging and care of technical notebooks (SOP-16).

  15. The (human) science of medical virtual learning environments

    2011-01-01

    The uptake of virtual simulation technologies in both military and civilian surgical contexts has been both slow and patchy. The failure of the virtual reality community in the 1990s and early 2000s to deliver affordable and accessible training systems stems not only from an obsessive quest to develop the ‘ultimate’ in so-called ‘immersive’ hardware solutions, from head-mounted displays to large-scale projection theatres, but also from a comprehensive lack of attention to the needs of the end users. While many still perceive the science of simulation to be defined by technological advances, such as computing power, specialized graphics hardware, advanced interactive controllers, displays and so on, the true science underpinning simulation—the science that helps to guarantee the transfer of skills from the simulated to the real—is that of human factors, a well-established discipline that focuses on the abilities and limitations of the end user when designing interactive systems, as opposed to the more commercially explicit components of technology. Based on three surgical simulation case studies, the importance of a human factors approach to the design of appropriate simulation content and interactive hardware for medical simulation is illustrated. The studies demonstrate that it is unnecessary to pursue real-world fidelity in all instances in order to achieve psychological fidelity—the degree to which the simulated tasks reproduce and foster knowledge, skills and behaviours that can be reliably transferred to real-world training applications.

  19. Four Finalist Landing Site Candidates for Mars Science Laboratory

    NASA Technical Reports Server (NTRS)

    2008-01-01

    Out of more than 30 sites considered as possible landing targets for NASA's Mars Science Laboratory mission, by November 2008 four of the most intriguing places on Mars rose to the final round of the site-selection process.

    The four finalists are, alphabetically: Eberswalde, where an ancient river deposited a delta in a possible lake; Gale, with a mountain of stacked layers including clays and sulfates; Holden, a crater containing alluvial fans, flood deposits, possible lake beds and clay-rich deposits; and Mawrth, which shows exposed layers containing at least two types of clay.

    The locations of these four candidates are indicated here on a background map of color-coded topographical data from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor. Red is higher elevation; blue is lower elevation. In latitude, the map extends from 70 degrees (north) to minus 70 degrees (south). The east-west axis is labeled at the top in degrees of east longitude, with the zero meridian at the center.

    The Mars Science Laboratory mission's capabilities for landing more precisely and at higher elevation than ever before, for driving farther, and for generating electricity without reliance on sunshine have enabled consideration of a wider range of possible landing sites than for any previous Mars mission. During the past two years, multiple observations of dozens of candidate sites by NASA's Mars Reconnaissance Orbiter have augmented data from earlier orbiters for evaluating sites' scientific attractions and engineering risks.

    More than 100 Mars scientists have participated in a series of open workshops presenting and assessing data that the orbiters have provided about the candidate sites. The four sites rated highest by researchers at a September 2008 workshop were the same ones chosen by mission leaders after a subsequent round of safety evaluations and analysis of terrain for rover driving.

    Vanderbilt University has realized the design and construction of a 1635 sq. ft. Class 10,000 cleanroom facility to support the wide-ranging research mission associated with the Vanderbilt Institute for Nanoscale Science and Engineering (VINSE). By design we have brought together disparate technologies and researchers formerly dispersed across the campus to work together in a small contiguous space intended to foster interaction and synergy of nano-technologies not often found in close proximity. The space hosts a variety of tools for lithographic patterning of substrates, the deposition of thin films, the synthesis of diamond nanostructures and carbon nanotubes, and a variety of reactive ion etchers for the fabrication of nanostructures on silicon substrates. In addition, a separate 911 sq. ft. chemistry laboratory supports nanocrystal synthesis and the investigation of biomolecular films. The design criteria required an integrated space that would support the scientific agenda of the laboratory while satisfying all applicable code and safety concerns. This project required the renovation of pre-existing laboratory space with minimal disruption to ongoing activities in a mixed-use building, while meeting the requirements of the 2000 edition of the International Building Code for the variety of potentially hazardous processes that have been programmed for the space. In this paper we describe how architectural and engineering challenges were met in the areas of mitigating floor vibration issues, shielding our facility against EMI emanations, design of the contamination control facility itself, chemical storage and handling, toxic gas use and management, as well as mechanical, electrical, plumbing, lab security, fire and laboratory safety issues.

    Since 2007, the rate of hospital bankruptcy has been rapidly increasing, and we face the crisis of a collapse in the medical care system. Even in hospitals that continue to operate, more than 70% are losing money. In the Department of Clinical Laboratory, the budget cannot be balanced using the present medical service fee payment system in the microbial examination field. Hospital managers may first consider outsourcing medical services from departments showing a budget imbalance. However, they should be aware that a decrease in medical services increases overall medical expenditure in the hospital. PMID:20077821

    The process of developing effective science educators has been a long-standing objective of the broader education community. Numerous studies have recommended not only depth in a teacher's subject area but also a breadth of professional development grounded in constructivist principles, allowing for successful student-centered and inquiry-based instruction. Few programs, however, have addressed the integration of the scientific research laboratory into the science classroom as a viable approach to professional development. Additionally, while occasional laboratory training programs have emerged in recent years, many lack a component for translating acquired skills into reformed classroom instruction. Given the rapid development and demand for knowledgeable employees and an informed population from the biotech and medical industries in recent years, it would appear to be particularly advantageous for the physiology and broader science education communities to consider this issue. The goal of this study was to examine the effectiveness of a laboratory-based professional development program focused on the integration of reformed teaching principles into the classrooms of secondary teachers. This was measured through the program's ability to instill in its participants elevated academic success while gaining fulfillment in the classroom. The findings demonstrated a significant improvement in the use of student-centered instruction and other reformed methods by program participants as well as improved self-efficacy, confidence, and job satisfaction. Also revealed was a reluctance to refashion established classroom protocols. The combination of these outcomes allowed for construction of an experiential framework for professional development in applied science education that supports an atmosphere of reformed teaching in the classroom.

    Aronova, Elena

    2009-01-01

    This paper examines the deployment of science studies within the field of medical ethics. For a short time, the discourse of medical ethics became a fertile ground for a dialogue between philosophically minded bioethicists and the philosophers of science who responded to Thomas Kuhn's challenge. In their discussion of the validity of Kuhn's work, these bioethicists suggested a distinct interpretation of Kuhn, emphasizing the elements in his account that had been independently developed by Michael Polanyi, and propelling a view of science that retreated from idealizations of scientific method without sacrificing philosophical realism. Appropriating Polanyi, they extended his account of science to biology and medicine. The contribution of Karl Popper to the debate on the applicability of philosophy of science to the issues of medical ethics provides the opportunity to discuss the ways in which political agendas of different epistemologies of science intertwined with questions of concern to medical ethics.

    2007-08-01

    The contribution of animal experimentation to biomedical research is of undoubted value, nevertheless the real usefulness of animal models is still being hotly debated. Laboratory Animal Science is a multidisciplinary approach to humane animal experimentation that allows the choice of the correct animal model and the collection of unbiased data. Refinement, Reduction and Replacement, the "3Rs rule", are now widely accepted and have a major influence on animal experimentation procedures. Refinement, namely any decrease in the incidence or severity of inhumane procedures applied to animals, has been today extended to the entire lives of the experimental animals. Reduction of the number of animals used to obtain statistically significant data may be achieved by improving experimental design and statistical analysis of data. Replacement refers to the development of validated alternative methods. A Laboratory Animal Science training program in biomedical degrees can promote the 3Rs and improve the welfare of laboratory animals as well as the quality of science with ethical, scientific and economic advantages complying with the European requirement that "persons who carry out, take part in, or supervise procedures on animals, or take care of animals used in procedures, shall have had appropriate education and training".

    Student experience surveys have become increasingly popular to probe various aspects of processes and outcomes in higher education, such as measuring student perceptions of the learning environment and identifying aspects that could be improved. This paper reports on a particular survey for evaluating individual experiments that has been developed over some 15 years as part of a large national Australian study pertaining to the area of undergraduate laboratories-Advancing Science by Enhancing Learning in the Laboratory. This paper reports on the development of the survey instrument and the evaluation of the survey using student responses to experiments from different institutions in Australia, New Zealand and the USA. A total of 3153 student responses have been analysed using factor analysis. Three factors, motivation, assessment and resources, have been identified as contributing to improved student attitudes to laboratory activities. A central focus of the survey is to provide feedback to practitioners to iteratively improve experiments. Implications for practitioners and researchers are also discussed.

    The 2011 Mars Science Laboratory will be the first Mars mission to attempt a guided entry to safely deliver the rover to a touchdown ellipse of 25 km x 20 km. The Entry Terminal Point Controller guidance algorithm is derived from the final phase Apollo Command Module guidance and, like Apollo, modulates the bank angle to control the range flown. For application to Mars landers which must make use of the tenuous Martian atmosphere, it is critical to balance the lift of the vehicle to minimize the range error while still ensuring a safe deploy altitude. An overview of the process to generate optimized guidance settings is presented, discussing improvements made over the last nine years. Key dispersions driving deploy ellipse and altitude performance are identified. Performance sensitivities including attitude initialization error and the velocity of transition from range control to heading alignment are presented.

    In 2011, the Mars Science Laboratory (MSL) will be launched in a mission to deliver the largest and most capable rover to date to the surface of Mars. A follow on MSL-derived mission, referred to as Mars 2018, is planned for 2018. Mars 2018 goals include performance enhancements of the Entry, Descent and Landing over that of its predecessor MSL mission of 2011. This paper will discuss the main elements of the modified 2018 EDL preliminary design that will increase performance on the entry phase of the mission. In particular, these elements will increase the parachute deploy altitude to allow for more time margin during the subsequent descent and landing phases and reduce the delivery ellipse size at parachute deploy through modifications in the entry reference trajectory design, guidance trigger logic design, and the effect of additional navigation hardware.

    The Mars Science Laboratory mission is the 2009 United States Mars Exploration Program rover mission. The MSL Project expects to complete its pre-Phase A definition activity this fiscal year (FY2003), investigations in mid-March 2004, launch in 2009, arrive at Mars in 2010 during Northern hemisphere summer and then complete a full 687 day Mars year of surface exploration. MSL will assess the potential for habitability (past and present) of a carefully selected landing region on Mars by exploring for the chemical building blocks of life, and seeking to understand quantitatively the chemical and physical environment with which these components have interacted over the geologic history of the planet. Thus, MSL will advance substantially our understanding of the history of Mars and potentially, its capacity to sustain life.

    The Mars Science Laboratory (MSL) is expected to be a long-range, long-duration science laboratory rover on the Martian surface. MSL will provide a significant milestone that paves the way for future landed missions to Mars. NASA is studying options to launch MSL as early as 2009. There are three elements to the spacecraft; carrier (cruise stage), entry vehicle, and rover. The rover will have a UHF proximity link as the primary path for EDL communications and may have an X-band direct-to-Earth link as a back-up. Given the importance of collecting critical event telemetry data during atmospheric entry, it is important to understand the ability of a signal link to be maintained, especially during the period near peak convective heating. The received telemetry during entry (or played back later) will allow for the performance of the Entry-Descent-Landing technologies to be assessed. These technologies include guided entry for precision landing, a new sky-crane landing system and powered descent. MSL will undergo an entry profile that may result in a potential communications blackout caused by ionized particles for short periods near peak heating. The vehicle will use UHF and possibly X-band during the entry phase. The purpose of this rep0rt is to quantify or bound the likelihood of any such blackout at UHF frequencies (401 MHz) and X-band frequencies (8.4 GHz). Two entry trajectory scenarios were evaluated: a stressful entry trajectory to quantify an upper-bound for any possible blackout period, and a nominal trajectory to quantify likelihood of blackout for such cases.

MSL will provide a significant milestone that paves the way for future landed missions to Mars. NASA is studying options to launch MSL as early as 2009. MSL will be the first mission to demonstrate the new technology of 'smart landers', which include precision landing and hazard avoidance in order to -land at scientifically interesting sites that would otherwise be unreachable. There are three elements to the spacecraft; carrier (cruise stage), entry vehicle, and rover. The rover will have an X-band direct-to-Earth (DTE) link as well as a UHF proximity link. There is also a possibility of an X-band proximity link. Given the importance of collecting critical event telemetry data during atmospheric entry, it is important to understand the ability of a signal link to be maintained, especially during the period near peak convective heating.

  6. Medical information, health sciences librarians, and professional liability.

    As a gatekeeper to medical literature and a critical link in the delivery of information to physicians, the librarian's role raises the issue of the librarian's professional liability. The paper suggests several ways in which liability may attach to the librarian or the librarian's employers. Although the librarian's personal risk is negligible, the physician's exposure due to ineffective library work is substantial since the courts have held that a physician must keep abreast of progress in his field. Librarians can also become associated with professional liability actions as part of a case against a physician or hospital through the legal doctrine of vicarious liability. The paper concludes by suggesting several proactive steps for health sciences librarians to pursue to insulate themselves from professional liability and to insulate physicians and institutions from vicarious liability.

    This study tested the hypothesis that {open_quotes}There is no statistically significant mentoring variable, or linear combination of mentoring variables, affecting Missouri beginning secondary science teachers` SOC (Stages of Concern) with respect to science laboratory utilization. Demographic data analysis, SOC maximum peak score analysis, item analysis, Pearson r correlation analysis, and factor analysis techniques were applied to data collected from three survey instruments-Science Laboratory Concerns. Mentoring Perceptions, and Demographic-designed for this study. All potential respondents were included in the original mailings. A total of eighty-seven (51.1%) usable responses were obtained. The findings of the study were that four mentoring factors-Professional Assistance, Science Laboratory Assistance, Mentor Availability, and Classroom Instructional Assistance-were used to determine mentoring affects upon Missouri beginning secondary science teachers. Also, the most prevalent stage of concern was Stage 4 (Consequences). This indicated that Missouri beginning secondary science teachers were primarily concerned with the impact of science laboratory utilization upon student learning. Mentoring Factor Four (Classroom Instructional Assistance) was found to be significantly related to Missouri beginning secondary science teachers` stages of concern with respect to science laboratory utilization. Individual mentoring items also were found to be significantly related to science laboratory utilization stages of concern. These relationships were both positive and negative.

    Organizational behaviors are commonly acknowledged as fundamentals of organizational life that strongly influence both formal and informal organizational processes, interpersonal relationships, work environments, and pay and promotion policies. The current study aims to investigate political behavior tendencies among employees of Tehran University of Medical Sciences (TUMS). This cross-sectional, descriptive and analytical study was conducted on 810 TUMS employees at the headquarters of the Tehran University of Medical Sciences, Iran during 2010–2011. The research tool for data collection was a researcher-tailored questionnaire on political behaviors. The validity of the questionnaire was confirmed by seven management professors, and its reliability was tested by a pilot study using test-retest method which yielded a Cronbach’s alpha coefficient of 0.71. The respondents were asked to fill the questionnaire and express their perceptions and tendencies to engage in organizational behaviors. The collected data was read to and analyzed by IBM SPSS environment and correlation analytical methods. Overall, 729 respondents filled and returned the questionnaire yielding a response rate of 90%. Most of the respondents indicated that they had no tendency to engage in political behavior. Moreover, we found that there was a significant correlation between sex, higher education degrees, tenure and the employees’ tendency to engage in political behavior. The participants were not overtly political because of their personal belief, ethical values, and personal characters. Non-political and overtly political employees are both prejudicial for all organizations. Therefore, it seems that the medium rate of good political behavior is vital and prevalent in Iranian organizations. PMID:23908760

    The Mars Science Laboratory (MSL) mission landed the Curiosity Rover on the surface of Mars on August 6, 2012, beginning a one-Martian-year primary science mission. An international network of Mars relay orbiters, including NASA's 2001 Mars Odyssey Orbiter (ODY) and Mars Reconnaissance Orbiter (MRO), and ESA's Mars Express Orbiter (MEX), were positioned to provide critical event coverage of MSL's Entry, Descent, and Landing (EDL). The EDL communication plan took advantage of unique and complementary capabilities of each orbiter to provide robust information capture during this critical event while also providing low-latency information during the landing. Once on the surface, ODY and MRO have provided effectively all of Curiosity's data return from the Martian surface. The link from Curiosity to MRO incorporates a number of new features enabled by the Electra and Electra-Lite software-defined radios on MRO and Curiosity, respectively. Specifically, the Curiosity-MRO link has for the first time on Mars relay links utilized frequency-agile operations, data rates up to 2.048 Mb/s, suppressed carrier modulation, and a new Adaptive Data Rate algorithm in which the return link data rate is optimally varied throughout the relay pass based on the actual observed link channel characteristics. In addition to the baseline surface relay support by ODY and MRO, the MEX relay service has been verified in several successful surface relay passes, and MEX now stands ready to provide backup relay support should NASA's orbiters become unavailable for some period of time.

    The Mars Science Laboratory (MSL), comprising a cruise stage; an aeroshell; an entry, descent, and landing system; and the radioisotope thermoelectric generator-powered Curiosity rover, made history with its unprecedented sky crane landing on Mars on August 6, 2012. The mission's primary science objective has been to explore the area surrounding Gale Crater and assess its habitability for past life. Because microbial contamination could profoundly impact the integrity of the mission and compliance with international treaty was required, planetary protection measures were implemented on MSL hardware to verify that bioburden levels complied with NASA regulations. By applying the proper antimicrobial countermeasures throughout all phases of assembly, the total bacterial endospore burden of MSL at the time of launch was kept to 2.78×10⁵ spores, well within the required specification of less than 5.0×10⁵ spores. The total spore burden of the exposed surfaces of the landed MSL hardware was 5.64×10⁴, well below the allowed limit of 3.0×10⁵ spores. At the time of launch, the MSL spacecraft was burdened with an average of 22 spores/m², which included both planned landed and planned impacted hardware. Here, we report the results of a campaign to implement and verify planetary protection measures on the MSL flight system. PMID:24432776

    The Mars Science Laboratory (MSL) is a spacecraft being developed by the Jet Propulsion Laboratory (JPL) for the purpose of in-situ exploration on the surface of Mars. The objective of MSL is to explore and quantitatively assess a local region on the Martian surface as a habitat for microbial life, past or present. This objective will be accomplished through the assessment of the biological potential of at least one target environment, the characterization of the geology and geochemistry of the landing region, an investigation of the planetary process relevant to past habitability, and a characterization of surface radiation. For this purpose, MSL incorporates a total of ten scientific instruments for which functions are to include, among others, atmospheric and descent imaging, chemical composition analysis, and radiation measurement. The Flight Software (FSW) system is responsible for all mission phases, including launch, cruise, entry-descent-landing, and surface operation of the rover. Because of the essential nature of flight software to project success, each of the software modules is undergoing extensive testing to identify and correct errors.

    The Astrochemistry Laboratory in the Astrophysics Branch (SSA) of the Space Sciences Division at NASA's Ames Research Center specializes in the study of extraterrestrial materials and their analogs. The staff has pioneered laboratory studies of space environments including interstellar, cometary, and planetary ices, simulations of the so-called 'Unidentified' Infrared Emission Bands and Diffuse Interstellar Bands using PAHs (Polycyclic Aromatic Hydrocarbons) and PAH-related materials, and has extensive experience with low-temperature spectroscopy and astronomical observation. Important discoveries made by the Astrochemistry Group include: (1) The recognition that polycyclic aromatic hydrocarbons and their ions are common in space; (2) The identification of a major fraction of the known molecular species frozen in interstellar/pre-cometary ices; (3) The recognition that a significant fraction of the carbon in the interstellar medium is carried by both microdiamonds and organic materials; (4) The expansion of the types of molecules expected to be synthesized in interstellar/pre-cometary ices. These could be delivered to the early Earth (or other body) and influence the origin or early evolution of life.

    Korbusieski, Todd J.

    The purpose of this research study is to examine the perceptions that principals have concerning school safety, particularly science laboratory classroom safety and to identify generalized safety equipment deficiencies as they pertain to public schools in North Carolina. Four questions were addressed in this study: First, are principals aware of specific laboratory safety equipment and policies that may create safer conditions in schools and science laboratory classrooms? Second, does an administrator's assignment (elementary, middle, or high school) have an affect on that person's level of science laboratory safety knowledge? Third, to what extent do principals perceive that it is important to ensure a safe science laboratory classroom? Fourth, what percentage of principals has had any formal training in science laboratory safety instruction? Descriptive research methodology was chosen using an electronic questionnaire. The questionnaire was e-mailed to all principals of public schools in the state of North Carolina. Four concerns were addressed in this questionnaire: (a) demographics including grade level, enrollment of school, years of experience, and area of teaching certificate; (b) administrator's background knowledge of science safety; (c) administrator's responsibilities concerning science laboratory safety; and (d) knowledge and availability of science safety devices. Principals in general felt their knowledge of science laboratory safety was minimal. Statistical analysis showed that high school principals did report more knowledge of science safety than their middle and elementary school counterparts. Also elementary principals perceived science laboratory safety as less important than their middle and high school counterparts. Only 1/3 of all principals reported that they had any formal science laboratory training either as teachers or as administrators. There is a wide difference in the perceived importance of safety knowledge and the actual knowledge

  1. Discourse in science communities: Issues of language, authority, and gender in a life sciences laboratory

    NASA Astrophysics Data System (ADS)

    Conefrey, Theresa Catherine

    Government-sponsored and private research initiatives continue to document the underrepresentation of women in the sciences. Despite policy initiatives, women's attrition rates each stage of their scientific careers remain higher than those of their male colleagues. In order to improve retention rates more information is needed about why many drop out or do not succeed as well as they could. While broad sociological studies and statistical surveys offer a valuable overview of institutional practices, in-depth qualitative analyses are needed to complement these large-scale studies. This present study goes behind statistical generalizations about the situation of women in science to explore the actual experience of scientific socialization and professionalization. Beginning with one reason often cited by women who have dropped out of science: "a bad lab experience," I explore through detailed observation in a naturalistic setting what this phrase might actually mean. Using ethnographic and discourse analytic methods, I present a detailed analysis of the discourse patterns in a life sciences laboratory group at a large research university. I show how language accomplishes the work of indexing and constituting social constraints, of maintaining or undermining the hierarchical power dynamics of the laboratory, of shaping members' presentation of self, and of modeling social and professional skills required to "do science." Despite the widespread conviction among scientists that "the mind has no sex," my study details how gender marks many routine interactions in the lab, including an emphasis on competition, a reinforcement of sex-role stereotypes, and a conversational style that is in several respects more compatible with men's than women's forms of talk.

    In 2010, the Mars Science Laboratory (MSL) mission will pioneer the next generation of robotic Entry, Descent, and Landing (EDL) systems, by delivering the largest and most capable rover to date to the surface of Mars. To do so, MSL will fly a guided lifting entry at a lift-to-drag ratio in excess of that ever flown at Mars, deploy the largest parachute ever at Mars, and perform a novel Sky Crane maneuver. Through improved altitude capability, increased latitude coverage, and more accurate payload delivery, MSL is allowing the science community to consider the exploration of previously inaccessible regions of the planet. The MSL EDL system is a new EDL architecture based on Viking heritage technologies and designed to meet the challenges of landing increasing massive payloads on Mars. In accordance with level-1 requirements, the MSL EDL system is being designed to land an 850 kg rover to altitudes as high as 1 km above the Mars Orbiter Laser Altimeter defined areoid within 10 km of the desired landing site. Accordingly, MSL will enter the largest entry mass, fly the largest 70 degree sphere-cone aeroshell, generate the largest hypersonic lift-to-drag ratio, and deploy the largest Disk-Gap-Band supersonic parachute of any previous mission to Mars. Major EDL events include a hypersonic guided entry, supersonic parachute deploy and inflation, subsonic heatshield jettison, terminal descent sensor acquisition, powered descent initiation, sky crane terminal descent, rover touchdown detection, and descent stage flyaway. Key performance metrics, derived from level-1 requirements and tracked by the EDL design team to indicate performance capability and timeline margins, include altitude and range at parachute deploy, time on radar, and propellant use. The MSL EDL system, which will continue to develop over the next three years, will enable a notable extension in the advancement of Mars surface science by delivering more science capability than ever before to the surface of

    Introduction Triage is a response to the problem of overcrowding in Emergency Departments (EDs) and accuracy of decisions made by the triage unit affects the ultimate outcome of EDs. This study was conducted to evaluate the knowledge of triage among last year medical students in Shiraz University of Medical Sciences. Methods This is a cross-sectional analytical study whose subjects were all the senior students of medicine (62) in the last year of medicine from January to June 2013 who attended emergency medicine course in the screen room of 2 University Hospitals. This questionnaire was designed in 3 sections including personal data, 15 questions on knowledge of triage and 10 case scenarios for triage decision making and completed by the students. Statistical analysis was performed in SPSS statistical software (version 14) using independent sample t-test, one way ANOVA, and Pearson correlation coefficient (p≤0.001). Results The total mean score of the participants was 10.6±1.5, ranging from 7 to 13. 58(93.5%) students had poor triage knowledge. In the scenario’s section, the percentage of correct triage by students was 49.2% and those of over and under triage were 28.1% and 22.7%, respectively. There was a significant relationship between the triage accuracy and level of triage (ESI 4) (p≤0.001). Conclusion The level of knowledge of triage in the last year medical students was poor, although most of them had passed a course in the screen room. It is recommended that medical students’ educational courses should include sections on the knowledge of triage in emergency rooms. PMID:27382582

    The science laboratory is an integral component of science education. However, the academic value of student participation in the laboratory is not clearly understood. One way to discern student perceptions of the science laboratory is by exploring their views of the classroom environment. The classroom environment is one determinant that can directly influence student learning and affective outcomes. Therefore, this study sought to examine community college students' perceptions of the laboratory classroom environment and their attitudes toward science. Quantitative methods using two survey instruments, the Science Laboratory Environment Instrument (SLEI) and the Test of Science Related Attitudes (TORSA) were administered to measure laboratory perceptions and attitudes, respectively. A determination of differences among males and females as well as three academic streams were examined. Findings indicated that overall community college students had positive views of the laboratory environment regardless of gender of academic major. However, the results indicated that the opportunity to pursue open-ended activities in the laboratory was not prevalent. Additionally, females viewed the laboratory material environment more favorably than their male classmates did. Students' attitudes toward science ranged from favorable to undecided and no significant gender differences were present. However, there were significantly statistical differences between the attitudes of nonscience majors compared to both allied health and STEM majors. Nonscience majors had less positive attitudes toward scientific inquiry, adoption of scientific attitudes, and enjoyment of science lessons. Results also indicated that collectively, students' experiences in the laboratory were positive predicators of their attitudes toward science. However, no laboratory environment scale was a significant independent predictor of student attitudes. .A students' academic streams was the only significant

    Synchrotron radiation (SR)-based techniques provide unique capabilities to address scientific issues underpinning environmental remediation science and have emerged as major research tools in this field. The high intensity of SR sources and x-ray photon-in/photon-out detection allow noninvasive in-situ analysis of dilute, hydrated, and chemically/structurally complex natural samples. SR x-rays can be focused to beams of micron and sub-micron dimension, which allows the study of microstructures, chemical microgradients, and microenvironments such as in biofilms, pore spaces, and around plant roots, that may control the transformation of contaminants in the environment. The utilization of SR techniques in environmental remediation sciences is often frustrated, however, by an ''activation energy barrier'', which is associated with the need to become familiar with an array of data acquisition and analysis techniques, a new technical vocabulary, beam lines, experimental instrumentation, and user facility administrative procedures. Many investigators find it challenging to become sufficiently expert in all of these areas or to maintain their training as techniques evolve. Another challenge is the dearth of facilities for hard x-ray micro-spectroscopy, particularly in the 15 to 23 KeV range, which includes x-ray absorption edges of the priority DOE contaminants Sr, U, Np, Pu, and Tc. Prior to the current program, there were only two (heavily oversubscribed) microprobe facilities in the U.S. that could fully address this energy range (one at each of APS and NSLS); none existed in the Western U.S., in spite of the relatively large number of DOE laboratories in this region.

    The Mars Science Laboratory mission delivers the Curiosity rover to the surface of Mars in August 2012 to assess whether its Gale Crater field site ever was capable of supporting microbial life and preserving a record of life and past environmental conditions. The 150-km crater is one of many near Mars' dichotomy boundary in various states of exhumation as a result of massive regional deposition and erosion. The primary target for Curiosity is the 5-km high mound of stratified materials in the crater's center. Systematic variations in mineralogy and morphology through the section indicate that the sediments have witnessed major changes in regional, if not planetary processes, as far back as the Noachian. The Curiosity rover was conceived as both a robotic field geologist, as previous rovers, and a mobile geochemical laboratory. It is an integrated platform for exploration (via landing site accessibility and mobility), for monitoring (via meteorological and high-energy radiation sensors), for survey (via panoramic cameras and remote elemental analysis), for close inspection (via a hand-lens imager and contact spectrometer), and for geochemical sample analysis. The latter capability drives the size and complexity of the rover by requiring a sample acquisition, processing, and analysis system consisting of a 2-m robot arm, rotary percussion drill, sieves and portioning tools, and the analytical instruments themselves. Upon acquisition and processing, samples of powdered rock are delivered to instruments located inside the rover body for mineralogical identification using X-ray diffraction, and analysis of elemental, molecular, and isotopic composition (including organic compounds) using a combined mass spectrometer, gas chromatograph, and tunable-laser spectrometer suite. To ensure the quality and accuracy of measurements from these instruments, and their interpretation, the mission has met many challenges in areas such as organic cleanliness, control blanks, tool and

    The Mars Science Laboratory (MSL) Project is an aggressive mission launching in 2009 to deliver a new generation of rover safely to the surface of Mars and conduct comprehensive in situ investigations using a new generation of instruments. This system will be designed to land with precision and be capable of operating over a large percentage on the surface of Mars. It will have capabilities that will support NASA's scientific goals into the next decade of exphation. The MSL Technology program is developing a wide-range of technologies needed for this Mission and potentially other space missions. The MSL Technology Program reports to both the MSL Project and the Mars Technology Program (MTP). The dual reporting process creates a challenging management situation, but ensures the new technology meets both the specific MSL requirements and the broader Mars Program requirements. MTP is a NASA-wide technology development program managed by the Jet Propulsion Laboratory (JPL) and is divided into a Focused Program and a Base Program. The Focused Technology Program addresses technologies that are specific and critical to near-term missions, while the Base Technology Program addresses those technologies that are applicable to multiple missions and which can be characterized as longer term, higher risk, and high payoff technologies. The MSL Technology Program is under the Focused Program and is tightly coupled to MSL's mission milestones and deliverables. The technology budget is separate from the flight Project budget, but the technology s requirements and the development process are tightly coordinated with the Project. The Technology Program combines proven management techniques of flight projects with commercial and academic technology management strategies, to create a technology management program that meets the near-term requirements of MSL and the long-term requirements of MTP. This paper examines the initiation of 2002 MSL Technology program. Some of the areas

    In this paper, we introduce a Concept Graph Engine (CG-Engine) that generates patient specific personalized disease ranking based on the laboratory test data. CG-Engine uses the Unified Medical Language System database as medical knowledge base. The CG-Engine consists of two concepts namely, a concept graph and its attributes. The concept graph is a two level tree that starts at a laboratory test root node and ends at a disease node. The attributes of concept graph are: Relation types, Semantic types, Number of Sources and Symmetric Information between nodes. These attributes are used to compute the weight between laboratory tests and diseases. The personalized disease ranking is created by aggregating the weights of all the paths connecting between a particular disease and contributing abnormal laboratory tests. The clinical application of CG-Engine improves physician's throughput as it provides the snapshot view of abnormal laboratory tests as well as a personalized disease ranking. PMID:24109927

    The NASA Mars Science Laboratory (MSL) rover is the third-generation robotic vehicle planned for Mars exploration, scheduled to land on Mars in 2012. There are 15 cameras on board the rover, 10 of which have engineering functions and 5 of which are designed for scientific investigations. Four of the five science cameras are built by Malin Space Science Systems to acquire color images via an RGB Bayer pattern 1600×1200 pixel charge-coupled device. These cameras are categorized into three types: Mast Camera (Mastcam), of which two different versions will be flown; Mars Hand Lens Imager (MAHLI); and Mars Descent Imager (MARDI). These cameras will investigate Martian geology and geomorphology and provide the first color views of the Martian surface that are identical to the natural color provided by typical consumer digital cameras. The author designed and built the lenses for these MSL science cameras, Mastcam utilizes a 34-mm focal length F/8 and a 100-mm focal length F/10 lens; MAHLI utilizes a lens that varies from a 18.4-mm focal length F/9.8 (close focus) to 21.4-mm focal length F/8.5 (infinity focus); and MARDI utilizes a 9.7-mm focal length F/3 lens. The requirements, design, and performance of these lenses are described.

    Background: Webometrics refers to the quantitative study of science production, application, structure and technology in the cyber environment. Impact analysis, website collaboration, and recognition of core websites are regarded as the most practical advantages of webometrics. Furthermore, webometrics is applied in ranking studies for universities and academic institutes. This serves as an internationally approved means of academic ranking worldwide. Our study aimed to evaluate the webometric status of Isfahan University of Medical Sciences (IUMS) and its place in the Webometric Ranking of World Universities. We also tried to comment on how to improve the university’s webometric rank at national, regional, and international levels. Material and Methods: This was a descriptive cross-sectional study including all websites of Iranian universities. Census sampling was applied to cover all Iranian university websites. Then the websites were evaluated according to the latest criteria for the international webometric ranking methodology (Cyberometric Lab, July 2012) and their webometric rank at the international level as well as the changes in the rank between July 2012 and January 2013 were analyzed. The webometric rank of IUMS was compared with other medical universities at different levels as well. Findings: According to the findings, from July 2012 to January 2013, IUMS webometric rank improved by 707, 5 and 2 at international, national and ministerial levels, respectively. Moreover, the rank of IUMS for openness rose from 4477 to 193 during the mentioned period (∆ 4284). In excellence, the university rank did not change sensibly (1537 /1538). In the same period, the rank in presence shifted from 1137 to 1091. Meanwhile, growth in website impact was negative as the university impact rank declined from 3369 to 3393. Conclusion: It seems that impact as the most influential ranking indicator fails to grow proportionately as other factors of IUMS website. This is

    On July 10, 2007, the former Homestake Mine, Lead, South Dakota, was selected as the development site for the Deep Underground Science and Engineering Laboratory, to become the Sanford Underground Science and Engineering Laboratory at Homestake. Work on refurbishment and certification of the Ross Shaft began in August 2007 to effect pumping of water that had reached the 5000 level in late July. Completion of this work will allow a physics and geosciences laboratory to be constructed on the 4,850 ft level (1,478 m from the surface). Concurrent with reentry operations, several earth science research activities have been initiated. These early activities are as follows: (1) Seismic monitoring system: Accelerometers will be installed in surface boreholes and underground drifts as they become available as a result of the reentry work. (2) Evaluation of the 300 level (91 m), which has multiple locations for horizontal access, is ongoing. This near- surface level, with varying overburden thicknesses, offers excellent opportunities to investigate the "critical zone" in terms of hydrology, ecology, and geochemistry, yielding measurements of both moisture and carbon fluxes to evaluate fluid exchanges with the atmosphere. (3) Water and soil samples were collected in the Ross Shaft as part of the first reentry work. Molecular survey of microbial diversity showed the presence of mesophilic and thermophilic cellulose-degrading microorganisms. (4) Supercritical carbon dioxide injection experiments are being planned that will take advantage of three pairs of existing, nearly vertical, open 8-inch (0.2 m) boreholes that are easily accessible from the Ross Shaft. The candidate holes are located between the 1550 and the 2900 levels and are between 90 to 180 m in length (5) Monitoring of the response of the water during the dewatering operations will be facilitated by the use of existing boreholes. Ultimately, the dewatering operation provide access to the 8000 level (depth of 2,438 m

    Metabolomics is the latest of the "omic" technologies that involves comprehensive analysis of small molecule metabolites of an organism or a specific biological sample. Metabolomics provides an insight into the cell status and describes an actual health condition of organisms. Analysis of metabolome offers a unique opportunity to study the influence of genetic variation, disease, applied treatment or diet on endogenous metabolic state of organisms. There are many areas that might benefit from metabolomic research. In the article some applications of this novel "omic" technology in the field of medical sciences are presented. One of the most popular aims of metabolomic studies is biomarker discovery. Despite using the state-of-art analytical techniques along with advanced bioinformatic tools, metabolomic experiments encounter numerous difficulties and pitfalls. Challenges that researchers in the field of analysis of metabolome have to face include i.a., technical limitations, bioinformatic challenges and integration with other "omic" sciences. One of the grand challenges for studies in the field of metabolomics is to tackle the problem of data analysis, which is probably the most time consuming stage of metabolomic workflow and requires close collaboration between analysts, clinicians and experts in chemometric analysis. Implementation of metabolomics into clinical practice will be dependent on establishment of standardized protocols in analytical performance and data analysis and development of fit-for-purpose biomarker method validation. Metabolomics allows to achieve a sophisticated level of information about biological systems and opens up new perspectives in many fields of medicine, especially in oncology. Apart from its extensive cognitive significance, metabolomics manifests also a practical importance as it may lead to design of new non-invasive, sensitive and specific diagnostic techniques and development of new therapies.

All work is conducted within primary containment either within cabinet lines (for in vitro work) or large rigid half-suit isolators (for in vivo work). There are extensive aerobiological facilities at high containment and the use of these facilities will be reported. Research at Dstl is primarily focused on assessing and quantifying the hazard, and testing the efficacy of medical countermeasures against filoviruses. Fundamental research directed to the study and understanding of the infectious and pathogenic nature of the filoviruses, particularly in aerosols, will be reported. PMID:23012627

    A previously reported microarray data analysis by RISS algorithm on breast cancer showed over-expression of the growth factor receptor (Grb7) and it also highlighted Tweety (TTYH1) gene to be under expressed in breast cancer for the first time. Our aim was to validate the results obtained from the microarray analysis with respect to these genes. Also, the relationship between their expression and the different prognostic indicators was addressed. RNA was extracted from the breast tissue of 30 patients with primary malignant breast cancer. Control samples from the same patients were harvested at a distance of ≥5 cm from the tumour. Semi-quantitative RT-PCR analysis was done on all samples. There was a significant difference between the malignant and control tissues as regards Grb7 expression. It was significantly related to the presence of lymph node metastasis, stage and histological grade of the malignant tumours. There was a significant inverse relation between expression of Grb7 and expression of both oestrogen and progesterone receptors. Grb7 was found to be significantly related to the biological classification of breast cancer. TTYH1 was not expressed in either the malignant or the control samples. The RISS by our group algorithm developed was laboratory validated for Grb7, but not for TTYH1. The newly developed software tool needs to be improved. PMID:25182704

    The use of contrast media such as organic iodine molecules and gadolinium contrast agents is commonplace in diagnostic imaging. Although there is widespread perception that side effects and drug interactions may be the leading problems caused by these compounds, various degrees of interference with some laboratory tests have been clearly demonstrated. Overall, the described interference for iodinate contrast media include inappropriate gel barrier formation in blood tubes, the appearance of abnormal peaks in capillary zone electrophoresis of serum proteins, and a positive bias in assessment of cardiac troponin I with one immunoassay. The interference for gadolinium contrast agents include negative bias in calcium assessment with ortho-cresolphthalein colorimetric assays and occasional positive bias using some Arsenazo reagents, negative bias in measurement of angiotensin converting enzyme (ACE) and zinc (colorimetric assay), as well as positive bias in creatinine (Jaffe reaction), total iron binding capacity (TIBC, ferrozine method), magnesium (calmagite reagent) and selenium (mass spectrometry) measurement. Interference has also been reported in assessment of serum indices, pulse oximetry and methaemoglobin in samples of patients receiving Patent Blue V. Under several circumstances the interference was absent from manufacturer-supplied information and limited to certain type of reagents and/or analytes, so that local verification may be advisable to establish whether or not the test in use may be biased. Since the elimination half-life of these compounds is typically lower than 2 h, blood collection after this period may be a safer alternative in patients who have received contrast media for diagnostic purposes.

    2005-01-01

    The Mars Science Laboratory mission intends to deliver a large rover to the Martian surface within 10 km of its target site. One candidate entry vehicle aeroshell consists of a 3.75-m diameter, 70-deg sphere-cone forebody and a biconic afterbody similar to that of Viking. This paper presents computational fluid dynamics predictions of laminar afterbody heating rates for this configuration and a 2010 arrival at Mars. Computational solutions at flight conditions used an 8-species Mars gas model in chemical and thermal non-equilibrium. A grid resolution study examined the effects of mesh spacing on afterbody heating rates and resulted in grids used for heating predictions on a reference entry trajectory. Afterbody heating rate reaches its maximum value near 0.6 W/sq cm on the first windward afterbody cone at the time of peak freestream dynamic pressure. Predicted afterbody heating rates generally are below 3% of the forebody laminar nose cap heating rate throughout the design trajectory. The heating rates integrated over time provide total heat load during entry, which drives thermal protection material thickness.

    The Program to Optimize Simulated Trajectories II (POST 2) has been successful in simulating the flight of launch vehicles and entry bodies on earth and other planets. POST 2 has been the primary simulation tool for the Entry Descent, and Landing (EDL) phase of numerous Mars lander missions such as Mars Pathfinder in 1997, the twin Mars Exploration Rovers (MER-A and MER-B) in 2004, Mars Phoenix lander in 2007, and it is now the main trajectory simulation tool for Mars Science Laboratory (MSL) in 2012. In all previous missions, the POST 2 simulation ended before ground impact, and a tool other than POST 2 simulated landing dynamics. It would be ideal for one tool to simulate the entire EDL sequence, thus avoiding errors that could be introduced by handing off position, velocity, or other fight parameters from one simulation to the other. The desire to have one continuous end-to-end simulation was the motivation for developing the ground interaction model in POST 2. Rover landing, including the detection of the postlanding state, is a very critical part of the MSL mission, as the EDL landing sequence continues for a few seconds after landing. The method explained in this paper illustrates how a simple ground force interaction model has been added to POST 2, which allows simulation of the entire EDL from atmospheric entry through touchdown.

    Viscous Laminar-turbulent transition plays an important role in the design of the Mars Science Laboratory (MSL) entry vehicle. The lift-to-drag ratio required for the precision landing trajectory will be achieved via an angle of attack equal to 16 degrees. At this relatively high angle of attack, the boundary layer flow near the leeward meridian is expected to transition early in the trajectory, resulting in substantially increased heating loads. This paper presents stability calculations and transition correlations for a series of wind tunnel models of the MSL vehicle. Experimentally measured transition onset locations are used to correlate with the N-factor calculations for various wind tunnel conditions. Due to relatively low post-shock Mach numbers near the edge of the boundary layer, the dominant instability waves are found to be of the first mode type. The N-factor values correlating with measured transition onset at selected test points from the Mach 6 conventional facility experiments fall between 3.5 and 4.5 and apparently vary linearly with the wind tunnel unit Reynolds number, indicating strong receptivity effect. The small transition N value is consistent with previous correlations for second-mode dominant transition in the same wind tunnel facility. Stability calculations for stationary and traveling crossflow instability waves in selected configurations indicate that an N value of 4 and 6, respectively, correlates reasonably well with transition onset discerned from one experimentally measured thermographic image.

    High energy and nuclear physics research at MIT is conducted within the Laboratory for Nuclear Science (LNS). Almost half of the faculty in the MIT Physics Department carry out research in LNS at the theoretical and experimental frontiers of subatomic physics. Since 2004, the U.S. Department of Energy has funded the high energy physics research program through grant DE-FG02-05ER41360 (other grants and cooperative agreements provided decades of support prior to 2004). The Director of LNS serves as PI. The grant supports the research of four groups within LNS as “tasks” within the umbrella grant. Brief descriptions of each group are given here. A more detailed report from each task follows in later sections. Although grant DE-FG02-05ER41360 has ended, DOE continues to fund LNS high energy physics research through five separate grants (a research grant for each of the four groups, as well as a grant for AMS Operations). We are pleased to continue this longstanding partnership.

  13. Mars Science Laboratory diurnal moisture observations and column simulations

    Hourly observations of air temperature and relative humidity at 1.6 m height from the surface (T 1.6 m, RH 1.6 m) measured by the Mars Science Laboratory (MSL) Rover Environmental Monitoring Station relative humidity (REMS-H) device are shown for MSL solar days 15-17 and 80-82, augmented with column model simulations. The diurnal range of T 1.6 m was 197-268 K in the first period, RH 1.6 m being small (<1%) in daytime but increasing to 45-49% by sunrise. During the warmer second period the T 1.6 m range was 201-275 K with RH 1.6 m only up to 16% in the morning. The modeled temperatures were quite close to those observed when the local albedo was set to 0.15 and thermal inertia to 300 tiu. The modeled RH 1.6 m was close to that observed when the well-mixed boundary layer values (0-4 km) of the mass mixing ratio q were 28-30 ppmm (suggesting a precipitable water content (PWC) of ~5.5 µm) during the first period and 12 ppmm (PWC of ~2 µm) during the second period. The REMS-H observations indicate systematic diurnal variation in the near-surface mixing ratio.

  14. Atmospheric Laboratory for Applications and Science (ATLAS), mission 1: Introduction

    NASA Technical Reports Server (NTRS)

    1988-01-01

    The first Atmospheric Laboratory for Applications and Science (ATLAS 1) is a NASA mission with an international payload, with the European Space Agency providing operational support for the European investigations. The ATLAS 1 represents the first of a series of shuttle-borne payloads which are intended to study the composition of the middle atmosphere and its possible variations due to solar changes over the course of an 11-year solar cycle. One of the ATLAS missions will coincide with NASA's Upper Atmospheric Research Satellite (UARS) mission and will provide crucial parameters not measured by the instrument complement on the satellite. A first in this evolutionary program, the ATLAS 1 will carry a payload of instruments originally flown on the Spacelab 1 and Spacelab 3 missions. The ATLAS mission therefore exploits the shuttle capability to return sophisticated instruments to the ground for refurbishment and updating, and the multi-mission reflight of the instruments at intervals required by the scientific goals. In addition to the investigations specific to the ATLAS objectives, the first mission payload includes others that are intended to study or use the near earth environment.

  15. Mars Science Laboratory Flight Software Boot Robustness Testing Project Report

    Roth, Brian

    2011-01-01

    On the surface of Mars, the Mars Science Laboratory will boot up its flight computers every morning, having charged the batteries through the night. This boot process is complicated, critical, and affected by numerous hardware states that can be difficult to test. The hardware test beds do not facilitate testing a long duration of back-to-back unmanned automated tests, and although the software simulation has provided the necessary functionality and fidelity for this boot testing, there has not been support for the full flexibility necessary for this task. Therefore to perform this testing a framework has been build around the software simulation that supports running automated tests loading a variety of starting configurations for software and hardware states. This implementation has been tested against the nominal cases to validate the methodology, and support for configuring off-nominal cases is ongoing. The implication of this testing is that the introduction of input configurations that have yet proved difficult to test may reveal boot scenarios worth higher fidelity investigation, and in other cases increase confidence in the robustness of the flight software boot process.

  16. Aerothermodynamic Environments Definition for the Mars Science Laboratory Entry Capsule

    2007-01-01

    An overview of the aerothermodynamic environments definition status is presented for the Mars Science Laboratory entry vehicle. The environments are based on Navier-Stokes flowfield simulations on a candidate aeroshell geometry and worst-case entry heating trajectories. Uncertainties for the flowfield predictions are based primarily on available ground data since Mars flight data are scarce. The forebody aerothermodynamics analysis focuses on boundary layer transition and turbulent heating augmentation. Turbulent transition is expected prior to peak heating, a first for Mars entry, resulting in augmented heat flux and shear stress at the same heatshield location. Afterbody computations are also shown with and without interference effects of reaction control system thruster plumes. Including uncertainties, analysis predicts that the heatshield may experience peaks of 225 W/sq cm for turbulent heat flux, 0.32 atm for stagnation pressure, and 400 Pa for turbulent shear stress. The afterbody heat flux without thruster plume interference is predicted to be 7 W/sq cm on the backshell and 10 W/sq cm on the parachute cover. If the reaction control jets are fired near peak dynamic pressure, the heat flux at localized areas could reach as high as 76 W/sq cm on the backshell and 38 W/sq cm on the parachute cover, including uncertainties. The final flight environments used for hardware design will be updated for any changes in the aeroshell configuration, heating design trajectories, or uncertainties.

    The Mars Science Laboratory (MSL) made a successful landing at Gale crater early August 2012. MSL has an environmental instrument package called the Rover Environmental Monitoring Station (REMS) as a part of its scientific payload. REMS comprises instrumentation for the observation of atmospheric pressure, temperature of the air, ground temperature, wind speed and direction, relative humidity (REMS-H), and UV measurements. We concentrate on describing the REMS-H measurement performance and initial observations during the first 100 MSL sols as well as constraining the REMS-H results by comparing them with earlier observations and modeling results. The REMS-H device is based on polymeric capacitive humidity sensors developed by Vaisala Inc., and it makes use of transducer electronics section placed in the vicinity of the three humidity sensor heads. The humidity device is mounted on the REMS boom providing ventilation with the ambient atmosphere through a filter protecting the device from airborne dust. The final relative humidity results appear to be convincing and are aligned with earlier indirect observations of the total atmospheric precipitable water content. The water mixing ratio in the atmospheric surface layer appears to vary between 30 and 75 ppm. When assuming uniform mixing, the precipitable water content of the atmosphere is ranging from a few to six precipitable micrometers. Key Points Atmospheric water mixing ratio at Gale crater varies from 30 to 140 ppm MSL relative humidity observation provides good data Highest detected relative humidity reading during first MSL 100 sols is RH75% PMID:26213667

    The Mars Science Laboratory (MSL) spacecraft is being designed to carry a large rover (greater than 800 kg) to the surface of Mars using a blunt-body entry capsule as the primary decelerator. The spacecraft is being designed for launch in 2009 and arrival at Mars in 2010. The combination of large mass and diameter with non-zero angle-of-attack for MSL will result in unprecedented convective heating environments caused by turbulence prior to peak heating. Navier-Stokes computations predict a large turbulent heating augmentation for which there are no supporting flight data1 and little ground data for validation. Consequently, an extensive experimental program has been established specifically for MSL to understand the level of turbulent augmentation expected in flight. The experimental data support the prediction of turbulent transition and have also uncovered phenomena that cannot be replicated with available computational methods. The result is that the flight aeroheating environments predictions must include larger uncertainties than are typically used for a Mars entry capsule. Finally, the thermal protection system (TPS) being used for MSL has not been flown at the heat flux, pressure, and shear stress combinations expected in flight, so a test program has been established to obtain conditions relevant to flight. This paper summarizes the aerothermodynamic definition analysis and TPS development, focusing on the challenges that are unique to MSL.

  19. Mars Science Laboratory with Arm Extended, Artist's Concept

    NASA Technical Reports Server (NTRS)

    2006-01-01

    NASA's Mars Science Laboratory, a mobile robot for investigating Mars' past or present ability to sustain microbial life, is in development for a launch opportunity in 2009. This picture is an artist's concept portraying what the advanced rover would look like in Martian terrain, from a side aft angle.

    The arm extending from the front of the rover is designed both to position some of the rover's instruments onto selected rocks or soil targets and also to collect samples for analysis by other instruments. Near the base of the arm is a sample preparation and handling system designed to grind samples, such as rock cores or small pebbles, and distribute the material to analytical instruments.

    The mast, rising to about 2.1 meters (6.9 feet) above ground level, supports two remote-sensing instruments: the Mast Camera for stereo color viewing of surrounding terrain and material collected by the arm, and the ChemCam for analyzing the types of atoms in material that laser pulses have vaporized from rocks or soil targets up to about 9 meters (30 feet) away.

  20. Dynamic Stability Testing of the Mars Science Laboratory Entry Capsule

    2009-01-01

    Results from a 26 shot ballistic range test of the Mars Science Laboratory (MSL) entry capsule are presented. The supersonic pitch damping properties of the MSL capsule were characterized between Mach 1.35 and Mach 3.5 and total angles-of-attack from 0 to 30 degrees. In flight, the MSL entry capsule will utilize a radial center-of-gravity offset to produce a non-zero trim angle-of-attack. This offset trim angle will produce lift, enabling the capsule to fly a guided entry and reducing the landing footprint dimensions to within 10 km of the desired landing site. A lifting configuration could not be tested at the ballistic range used for this test as the models would swerve into the range walls, possibly damaging cameras, the coordinate reference system or other facility assets. Ballistic (non-lifting) data was extracted and will be implemented in a conservative fashion to ensure that the dynamic stability characteristics of the flight vehicle are bounded. A comparison between the MSL pitch damping results and the dynamic model of the Mars Exploration Rover capsule shows generally close agreement with no significant differences in damping characteristics due to the change in backshell geometry. Dynamic moments are also compared to the MSL reaction control system (RCS) control authority to show the controller has sufficient margin to easily damp any dynamic stability effects.

    2004-01-01

    The Mars Science Laboratory (MSL) Project is an aggressive mission launching in 2009 to investigate the Martian environment and requires new capabilities that are currently are not available. The MSL Technology Program is developing a wide-range of technologies needed for this Mission and potentially other space missions. The MSL Technology Program reports to both the MSL Project and the Mars Technology Program (MTP). The dual reporting process creates a challenging management situation, but ensures the new technology meets both the specific MSL requirements and the broader Mars Program requirements. MTP is a NASA-wide technology development program managed by JPL and is divided into a Focused Program and a Base Program. The MSL Technology Program is under the focused program and is tightly coupled to MSL's mission milestones and deliverables. The technology budget is separate from the flight Project budget, but the technology's requirements and the development process are tightly coordinated with the Project. The MSL Technology Program combines the proven management techniques of flight projects with the commercial technology management strategies of industry and academia, to create a technology management program that meets the short-term requirements of MSL and the long-term requirements of MTP. This paper examines the initiation of 2002 MSL Technology program. Some of the areas discussed in this paper include technology definition, task selection, technology management, and technology assessment. This paper also provides an update of the 2003 MSL technology program and examines some of the drivers that changed the program from its initiation.

    In 2012, the Mars Science Laboratory (MSL) mission will pioneer the next generation of robotic Entry, Descent, and Landing (EDL) systems by delivering the largest and most capable rover to date to the surface of Mars. In addition to landing more mass than prior missions to Mars, MSL will offer access to regions of Mars that have been previously unreachable. The MSL EDL sequence is a result of a more stringent requirement set than any of its predecessors. Notable among these requirements is landing a 900 kg rover in a landing ellipse much smaller than that of any previous Mars lander. In meeting these requirements, MSL is extending the limits of the EDL technologies qualified by the Mars Viking, Mars Pathfinder, and Mars Exploration Rover missions. Thus, there are many design challenges that must be solved for the mission to be successful. Several pieces of the EDL design are technological firsts, such as guided entry and precision landing on another planet, as well as the entire Sky Crane maneuver. This paper discusses the MSL EDL architecture and discusses some of the challenges faced in delivering an unprecedented rover payload to the surface of Mars.

    2007-01-01

    In 2010 the Mars Science Laboratory (MSL) mission will deliver NASA's largest and most capable rover to the surface of Mars. MSL will explore previously unattainable landing sites due to the implementation of a high precision Entry, Descent, and Landing (EDL) system. The parachute decelerator subsystem (PDS) is an integral prat of the EDL system, providing a mass and volume efficient some of aerodynamic drag to decelerate the entry vehicle from Mach 2 to subsonic speeds prior to final propulsive descent to the sutface. The PDS for MSL is a mortar deployed 19.7m Viking type Disk-Gap-Band (DGB) parachute; chosen to meet the EDL timeline requirements and to utilize the heritage parachute systems from Viking, Mars Pathfinder, Mars Exploration Rover, and Phoenix NASA Mars Lander Programs. The preliminary design of the parachute soft goods including materials selection, stress analysis, fabrication approach, and development testing will be discussed. The preliminary design of mortar deployment system including mortar system sizing and performance predictions, gas generator design, and development mortar testing will also be presented.

    2009-01-01

    Aerothermodynamic design environments are presented for the Mars Science Laboratory entry capsule heatshield. The design conditions are based on Navier-Stokes flowfield simulations on shallow (maximum total heat load) and steep (maximum heat flux, shear stress, and pressure) entry trajectories from a 2009 launch. Boundary layer transition is expected prior to peak heat flux, a first for Mars entry, and the heatshield environments were defined for a fully-turbulent heat pulse. The effects of distributed surface roughness on turbulent heat flux and shear stress peaks are included using empirical correlations. Additional biases and uncertainties are based on computational model comparisons with experimental data and sensitivity studies. The peak design conditions are 197 W/sq cm for heat flux, 471 Pa for shear stress, 0.371 Earth atm for pressure, and 5477 J/sq cm for total heat load. Time-varying conditions at fixed heatshield locations were generated for thermal protection system analysis and flight instrumentation development. Finally, the aerothermodynamic effects of delaying launch until 2011 are previewed.

    The National Aeronautics and Space Administration (NASA) Dryden Flight Research Center (DFRC), (Edwards, California, USA) has two Lockheed Martin Corporation (Bethesda, Maryland) Earth Research-2 (ER-2) aircraft that serve as high-altitude and long-range flying laboratories. The ER-2 has been utilized to conduct scientific studies of stratospheric and tropospheric chemistry, land-use mapping, disaster assessment, preliminary testing and calibration and validation of satellite sensors. The ER-2 aircraft provides experimenters with a wide array of payload accommodation areas with suitable environment control with required electrical and mechanical interfaces. Missions may be flown out of DFRC or from remote bases worldwide. The NASA ER-2 is utilized by a variety of customers, including U.S. Government agencies, civilian organizations, universities, and state governments. The combination of the ER-2 s range, endurance, altitude, payload power, payload volume and payload weight capabilities complemented by a trained maintenance and operations team provides an excellent and unique platform system to the science community.

  6. Communications Blackout Prediction for Atmospheric Entry of Mars Science Laboratory

    NASA Technical Reports Server (NTRS)

    Morabito, David; Edquist, Karl

    2005-01-01

    When a supersonic spacecraft enters a planetary atmosphere with v >> v(sub sound), a shock layer forms in the front of the body. An ionized sheath of plasma develops around the spacecraft, which results from the ionization of the atmospheric constituents as they are compressed and heated by the shock or heated within the boundary layer next to the surface. When the electron density surrounding the spacecraft becomes sufficiently high, communications can be disrupted (attenuation/blackout). During Mars Science Laboratory's (MSL's) atmospheric entry there will likely be a communication outage due to charged particles on the order of 60 to 100 seconds using a UHF link frequency looking out the shoulders of the wake region to orbiting relay asset. A UHF link looking out the base region would experience a shorter duration blackout, about 35 seconds for the stressed trajectory and possibly no blackout for the nominal trajectory. There is very little likelihood of a communications outage using X-band (however, X-band is not currently planned to be used during peak electron density phase of EDL).

    Background: Academic failure of medical and medical sciences students is one of the major problems of higher education centers in many countries. This study aims to collect and compare relevant researches in this field in Iran. Methods: The appropriate keywords were searched in the national and international databases, and the findings were categorized into related and non-related articles accordingly. Results: Only 22 articles were included in this systematic review. In terms of content analysis, gender, living in a dorm, employment, marital status, age, special rights in the entrance exams, the time lag between diploma and university, diploma average, learning style, being nonnative students, being a transferred student, psychological problems, occupation of the mother, salary level, diploma type, field of study, self-esteem, exam anxiety and interest on the field of study were considered as the influential factors for academic failure of the students. Conclusion: This systematic review shows that there is no definite academic failure criterion. It is also suggested Iranian researchers should pay more attention on the documentation of the higher educational strategies that have been implemented to prevent avoidable academic failure and contain physiological academic failure.

    2002-10-01

    At the University of Kentucky (UK), we applied streaming video technology to develop a webcast model that will allow institutions to broadcast live and prerecorded surgeries, conferences, and courses in real time over networks (the Internet or an intranet). We successfully broadcast a prerecorded laparoscopic paraesophageal hernia repair to domestic and international clients by using desktop computers equipped with off-the-shelf, streaming-enabled software and standard hardware and operating systems. A web-based user interface made accessing the educational material as simple as a mouse click and allowed clients to participate in the broadcast event via an embedded e-mail/chat module. Three client computers (two connected to the Internet and a third connected to the UK intranet) requested and displayed the surgical film by means of seven common network connection configurations. Significantly, no difference in image resolution was detected with the use of a connection speed faster than 128 kilobytes per second (kbps). At this connection speed, an average bandwidth of 32.7 kbps was used, and although a 15-second delay was experienced from the time of data request to data display, the surgical film streamed continuously from beginning to end at a mean rate of 14.4 frames per second (fps). The clients easily identified all anatomic structures in full color motion, clearly followed all steps of the surgical procedure, and successfully asked questions and made comments by using the e-mail/chat module while viewing the surgery. With minimal financial investment, we have created an interactive virtual classroom with the potential to attract a global audience. Our webcast model represents a simple and practical method for institutions to supplement undergraduate and graduate surgical education and offer continuing medical education credits in a way that is convenient for clients (surgeons, students, residents, others). In the future, physicians may access streaming webcast

  9. A Sparse Hierarchical Map Representation for Mars Science Laboratory Science Operations

    We describe a solution for multi-scale Mars terrain modeling and mapping with Digital Elevation Models (DEMs) and co-registered orthogonally projected imagery (ortho-images). High resolution DEMs and ortho-images derived from Mars Science Laboratory (MSL) rover science and navigation cameras are represented in context with lower resolution, wide coverage DEMs and ortho-images derived from Mars Reconnaissance Orbiter (MRO) HiRISE and CTX camera images and Mars Express (MEX) mission HRSC images. Merging MSL rover image derived terrain models with those from orbital images at a uniform high resolution would require super-sampling of the orbital data across a large area to maintain significant context. This solution is not practical, and would result in a mapping product of enormous size. Instead, we choose a sparse hierarchical map representation. Each level in this hierarchical representation is a map described by a set of tiles with fixed number of samples and fixed resolution. The number of samples in a tile is fixed for all levels and each level is associated with a specific resolution. In this work, the resolution ratio between two adjacent levels is set to two. The map at each level is sparse and it contains only the tiles for which data is available at the resolution of the given level. For example, at the highest resolution level only MSL science camera models are available and only a small set of tiles are generated in a sparse map. At the lowest resolution, the map contains the complete set of tiles. The reference level of the representation is chosen to be the HiRISE terrain model and CTX, HRSC and MSL data are projected onto this model before being mapped. While our terrain representation was developed for use in "Antares", a visual planning and sequencing tool for MSL science cameras developed at NASA Ames Research Center, it is general purpose and has a number of potential geo-science visualization applications.

    2002-04-01

    In this study, research and development of a prototype background alarm levelled radioisotope dose calibrator for nuclear medical laboratories was emphasized. The aim was to develop a standard performance, economical dose calibrator (self-made) from the ion-chamber to the microcomputer. Dose calibrators are used in nuclear medical laboratories for treatment and diagnosis purposes. The device is developed using an ion chamber filled with 2 atm pressure argon gas, 3N201 dual gate mosfet for the extremely high impedance preamplifier, an Intel 8052AH microcontroller for the microcomputer, ADC0804 for the A/D conversion, a Phillips 2 x 16 character display, and other components. Correction factors are used for each radioisotope after the activity measurements, that can be updated and kept in the Ni-Cd rechargeable battery-powered RAM memory. To provide safety in nuclear medical laboratories, background activity values are measured. PMID:11993576

    1991-01-01

    The Unified Medical Language System (UMLS) was examined to determine its coverage of clinical laboratory terminology in use at the Columbia-Presbyterian Medical Center (CPMC). The Metathesaurus (Meta-1) contains exact matches for 30% of 1460 CPMC laboratory terms and near matches for an additional 42%, with better coverage of atomic-level concepts ("substance" terms) than complex ones (tests and panels). The Semantic Network includes types for representing laboratory procedures (2), measured substances (at least 56) and sampled substances (at least 14), but no type to represent specimens. Few of the UMLS semantic relationships are applicable to the CPMC vocabulary. These results have implications for the utility of the UMLS for linking clinical databases to electronic medical information sources. PMID:1807587

  3. The laboratory in science education: Foundations for the twenty-first century

    NASA Astrophysics Data System (ADS)

    Hofstein, Avi; Lunetta, Vincent N.

    2004-01-01

    The laboratory has been given a central and distinctive role in science education, and science educators have suggested that rich benefits in learning accrue from using laboratory activities. Twenty years have been elapsed since we published a frequently cited, critical review of the research on the school science laboratory (Hofstein & Lunetta, Rev. Educ. Res. 52(2), 201-217, 1982). Twenty years later, we are living in an era of dramatic new technology resources and new standards in science education in which learning by inquiry has been given renewed central status. Methodologies for research and assessment that have developed in the last 20 years can help researchers seeking to understand how science laboratory resources are used, how students' work in the laboratory is assessed, and how science laboratory activities can be used by teachers to enhance intended learning outcomes. In that context, we take another look at the school laboratory in the light of contemporary practices and scholarship. This analysis examines scholarship that has emerged in the past 20 years in the context of earlier scholarship, contemporary goals for science learning, current models of how students construct knowledge, and information about how teachers and students engage in science laboratory activities.

    2004-12-01

    A summary of efforts to create one or more Deep Underground Science and Engineering Laboratories (DUSEL) in the United States is presented. A workshop in Berkeley, August 11-14, 2004, explored the technical requirements of DUSEL for research in basic and applied geological and microbiological sciences, together with elementary particle physics and integrated education and public outreach. The workshop was organized by Bernard Sadoulet, an astrophysicist and the principal investigator (PI) of a community-wide DUSEL program evolving in coordination with the National Science Foundation. The PI team has three physicists (in nuclear science, high-energy physics, and astrophysics) and three earth scientists (in geoscience, biology and engineering). Presentations, working group reports, links to previous workshop/meeting talks, and information about DUSEL candidate sites, are presented in http://neutrino.lbl.gov/DUSELS-1. The Berkeley workshop is a continuation of decades of efforts, the most recent including the 2001 Underground Science Conference's earth science and geomicrobiology workshops, the 2002 International Workshop on Neutrino and Subterranean Science, and the 2003 EarthLab Report. This perspective (from three earth science co-PIs, the lead author of EarthLab report, the lead scientist of education/outreach, and the local earth science organizer) is to inform the community on the status of this national initiative, and to invite their active support. Having a dedicated facility with decades-long, extensive three-dimensional underground access was recognized as the most important single attribute of DUSEL. Many research initiatives were identified and more are expected as the broader community becomes aware of DUSEL. Working groups were organized to evaluate hydrology and coupled processes; geochemistry; rock mechanics/seismology; applications (e.g., homeland security, environment assessment, petroleum recovery, and carbon sequestration); geomicrobiology and

    The article asserts that a scientific discipline is defined by both its object of research or knowledge (domain) and its specific or adequate method. An appropriate definition should fulfill other necessary conditions implicit in certain fundamental rules of definition, e.g., a definition should not be too narrow or too broad. It should also respect well established uses of language, in which the concept to be defined may already have a given meaning. In Scandinavia there are three words used for the Science of Health Care. "Vårdvetenskap" e.g., is used both in Sweden and Finland. In Finland it is used to convey the view that care is essential to Man, and a holistic concept of Man/Health. So demarcated, Vårdvetenskapen complements Medicine which ontologically reduces Man to biochemistry and sickness to disease. To fulfill this function the Science of health Care should be humanistic and interdisciplinary, and not purely empirico-positivistic like Medicine. PMID:1842325

    One of the primary science goals of the Mars Science Laboratory (MSL) Rover, Curiosity, is the detection of organics in Mars rock and regolith. To achieve this, the Curiosity rover includes a robotic sampling system that acquires rock and regolith samples and delivers it to the Sample Analysis at Mars (SAM) instrument on board the rover. In order to provide confidence that any significant organics detection result was Martian and not terrestrial in origin, a requirement was levied on the flight system (i.e., all sources minus the SAM instrument) to impart no more than 36 parts per billion (ppb by weight) of total reduced carbon terrestrial contamination to any sample transferred to the SAM instrument. This very clean level was achieved by a combination of a rigorous contamination control program on the project, and then using the first collected samples for a "dilution cleaning" campaign of the sample chain prior to delivering a sample to the SAM instrument. Direct cleanliness assays of the sample-contacting and other Flight System surfaces during pre-launch processing were used as inputs to determine the number of dilution cleaning samples needed once on Mars, to enable delivery of suitably clean samples to the SAM experiment. Taking into account contaminant redistribution during launch thorough landing of the MSL on Mars, the amount of residue present on the sampling hardware prior to the time of first dilution cleaning sample acquisition was estimated to be 60 ng/cm(2) on exposed outer surfaces of the sampling hardware and 20 ng/cm(2) on internal sample contacting surfaces; residues consisting mainly of aliphatic hydrocarbons and esters. After three dilution cleaning samples, estimated in-sample contamination level for the first regolith sample delivered to the SAM instrument at the Gale Crater "Rocknest" site was bounded at ≤10 ppb total organic carbon.

  11. Mars Science Laboratory Heatshield Aerothermodynamics: Design and Reconstruction

    Edquist, Karl T.; Hollis, Brian R.; Johnston, Christopher O.; Bose, Deepak; White, Todd R.; Mahzari, Milad

    2013-01-01

    The Mars Science Laboratory heatshield was designed to withstand a fully turbulent heat pulse based on test results and computational analysis on a pre-flight design trajectory. Instrumentation on the flight heatshield measured in-depth temperatures in the thermal protection system. The data indicate that boundary layer transition occurred at 5 of 7 thermocouple locations prior to peak heating. Data oscillations at 3 pressure measurement locations may also indicate transition. This paper presents the heatshield temperature and pressure data, possible explanations for the timing of boundary layer transition, and a qualitative comparison of reconstructed and computational heating on the as-flown trajectory. Boundary layer Reynolds numbers that are typically used to predict transition are compared to observed transition at various heatshield locations. A uniform smooth-wall transition Reynolds number does not explain the timing of boundary layer transition observed during flight. A roughness-based Reynolds number supports the possibility of transition due to discrete or distributed roughness elements on the heatshield. However, the distributed roughness height would have needed to be larger than the pre-flight assumption. The instrumentation confirmed the predicted location of maximum turbulent heat flux near the leeside shoulder. The reconstructed heat flux at that location is bounded by smooth-wall turbulent calculations on the reconstructed trajectory, indicating that augmentation due to surface roughness probably did not occur. Turbulent heating on the downstream side of the heatshield nose exceeded smooth-wall computations, indicating that roughness may have augmented heating. The stagnation region also experienced heating that exceeded computational levels, but shock layer radiation does not fully explain the differences.

  12. Turbulent Aeroheating Testing of Mars Science Laboratory Entry Vehicle

    Hollis, Brian R.; Collier, Arnold S.

    2008-01-01

    An experimental investigation of turbulent aeroheating on the Mars Science Laboratory entry vehicle heat shield has been conducted in the Arnold Engineering Development Center Hypervelocity Wind Tunnel No. 9. Testing was performed on a 6-in. (0.1524 m) diameter MSL model in pure N2 gas in the tunnel's Mach 8 and Mach 10 nozzles at free stream Reynolds numbers of 4.1 x 10(exp 6)/ft to 49 x 10(exp 6)/ft (1.3 x 10(exp 7)/m to 19 x 10(exp 6/ft) and 1.2 x 10(exp 6)/ft to 19 x 10(exp 6)/ft (0.39 x 10(exp 7)/m to 62 x 10(exp 7)/m), respectively. These conditions were sufficient to span the regime of boundary-layer flow from completely laminar to fully-developed turbulent flow over the entire forebody. A supporting aeroheating test was also conducted in the Langley Research Center 20-Inch Mach 6 Air Tunnel at free stream Reynolds number of 1 x 10(exp 6)/ft to 7 x 10(exp 6)/ft (0.36 x 10(exp 7)/m to 2.2 x 10(exp 7)/m) in order to help corroborate the Tunnel 9 results. A complementary computational fluid dynamics study was conducted in parallel to the wind tunnel testing. Laminar and turbulent predictions were generated for the wind tunnel test conditions and comparisons were performed with the data for the purpose of helping to define uncertainty margins on predictions for aeroheating environments during entry into the Martian atmosphere. Data from both wind tunnel tests and comparisons with the predictions are presented herein. It was concluded from these comparisons that for perfect-gas conditions, the computational tools could predict fully-laminar or fully-turbulent heating conditions to within 12% or better of the experimental data.

  13. Mars Science Laboratory Rover Integrated Pump Assembly Bellows Jamming Failure

    NASA Technical Reports Server (NTRS)

    Johnson, Michael R.; Johnson, Joel; Birur, Gajanana; Bhandari, Pradeep; Karlmann, Paul

    2012-01-01

    The Mars Science Laboratory rover and spacecraft utilize two mechanically pumped fluid loops for heat transfer to and from the internal electronics assemblies and the Radioisotope Thermo-Electric Generator (RTG). The heat transfer fluid is Freon R-11 (CFC-11) which has a large coefficient of thermal expansion. The Freon within the heat transfer system must have a volume for safe expansion of the fluid as the system temperature rises. The device used for this function is a gas-over-liquid accumulator. The accumulator uses a metal bellows to separate the fluid and gas sections. During expansion and contraction of the fluid in the system, the bellows extends and retracts to provide the needed volume change. During final testing of a spare unit, the bellows would not extend the full distance required to provide the needed expansion volume. Increasing the fluid pressure did not loosen the jammed bellows either. No amount of stroking the bellows back and forth would get it to pass the jamming point. This type of failure, if it occurred during flight, would result in significant overpressure of the heat transfer system leading to a burst failure at some point in the system piping. A loss of the Freon fluid would soon result in a loss of the mission. The determination of the source of the jamming of the bellows was quite elusive, leading to an extensive series of tests and analyses. The testing and analyses did indicate the root cause of the failure, qualitatively. The results did not provide a set of dimensional limits for the existing hardware design that would guarantee proper operation of the accumulator. In the end, a new design was developed that relied on good engineering judgment combined with the test results to select a reliable enough solution that still met other physical constraints of the hardware, the schedule, and the rover system.

  18. Basic biomedical sciences and the future of medical education: implications for internal medicine.

    PubMed

    Brass, Eric P

    2009-11-01

    The academic model of medical education in the United States is facing substantial challenges. Apprenticeship experiences with clinical faculty are increasingly important in most medical schools and residency programs. This trend threatens to separate clinical education from the scientific foundations of medical practice. Paradoxically, this devaluation of biomedical science is occurring as the ability to use new discoveries to rationalize clinical decision making is rapidly expanding. Understanding the scientific foundations of medical practice and the ability to apply them in the care of patients separates the physician from other health care professionals. The de-emphasis of biomedical science in medical education poses particular dangers for the future of internal medicine as the satisfaction derived from the application of science to the solving of a clinical problem has been a central attraction of the specialty. Internists should be engaged in the ongoing discussions of medical education reform and provide a strong voice in support of rigorous scientific training for the profession. PMID:19882372

  19. Assessment and evaluation of science process skills in secondary school biology laboratories

    NASA Astrophysics Data System (ADS)

    Kujawinski, Daniel Bernard

    Awareness of the importance of process skills in science education has increased, but practical methods of assessing student performance of these skills has received minimal attention. The purpose of this dissertation is to examine how student science process skills may be accurately and reliably measured and evaluated. A set of laboratory activities that emphasized process skills was developed by 12 science educators from the western New York area who were participants in a summer institute sponsored by the Howard Hughes Medical Institute. These innovative laboratory activities were designed to be used in existing secondary school biology courses by students of different ages and ability levels. Student performance in the four general process categories of planning, performing, reasoning, and communicating was broken down into twenty specific, individual science process skills deemed important to science education. Nine teacher developers used these twelve activities, entirely and/or partially with their high school biology students during the 1995-1996 school year. Two types of assessment instruments were developed and field-tested for the purpose of evaluating student self evaluation and performance of the twenty individual science process skills. The first was an inventory that asked for the students' self-evaluation of their abilities to perform each of the twenty process skills based on the current year's laboratory experiences. The second was a set of three performance tasks which assessed the twenty skills and were to be completed by the students in a laboratory setting under supervision of their classroom teacher and the researcher. During May and early June, 1996, the student self-evaluation inventory and the three performance tasks were administered to 94 students of teachers in 6 schools who developed and used the activities (HH95, experimental group) and to 126 students of teachers in 9 schools that did not use the activities (HH96, control group).

    The core concept of plagiarism is defined as the use of other people's ideas or words without proper acknowledgement. Herein, we used a questionnaire to assess the knowledge of students of Tehran University of Medical Sciences (TUMS) regarding plagiarism and copyright infringement. The questionnaire comprised 8 questions. The first six questions of the questionnaire were translations of exercises of a book about academic writing and were concerning plagiarism in preparing articles. Questions number 7 and 8 (which were concerning plagiarism in preparing Microsoft PowerPoint slideshows and copyright infringement, respectively) were developed by the authors of the present study. The validity of the questionnaire was approved by five experts in the field of epidemiology and biostatistics. A pilot study consisting of a test and retest was carried to assess the reliability of the questionnaire. The sampling method was stratified random sampling, and the questionnaire was handed out to 74 interns of TUMS during July and August 2011. 14.9% of the students correctly answered the first six questions. 44.6% of the students were adequately familiar with proper referencing in Microsoft PowerPoint slideshows. 16.2% of the students understood what constitutes copyright infringement. The number of correctly answered questions by the students was directly proportionate to the number of their published articles. Knowledge of students of TUMS regarding plagiarism and copyright infringement is quite poor. Courses with specific focus on plagiarism and copyright infringement might help in this regard.

  12. The impact of longer term intervention on reforming physical science teachers' approaches to laboratory instruction: Seeking a more effective role for the laboratory in science instruction

    NASA Astrophysics Data System (ADS)

    Priestley, William Joseph

    This study is one of six companion studies investigating ways of improving the overall role of laboratory experiences in science instruction. The primary purpose of the study was to explore the extent to which longer term inservice experiences with modeled inquiry-based instruction caused immediate reform in the approach that inservice teachers of physical science use in pre- and post-laboratory instruction, as well as their ability to restructure their physical science courses to give greater emphasis to the inquiry approach. A secondary purpose was to compare the findings of this study with those of the companion study by H. Priestley (1996) which studied life science teachers (LSTs). A full semester graduate level science education course entitled Science Education 716, The Teaching of Chemistry, developed by two experienced Temple University professors, provided the necessary modeled inquiry-oriented pedagogical approach. Pre- and post-laboratory sessions were videotaped and analyzed using the Modified Revised Science Teacher Behavioral Inventory to determine the frequency of occurrence of the teaching behaviors used. Inservice teacher behavior profiles were compared to the profiles of traditional and model teaching. Eleven of the 14 PSTs presented post-laboratory sessions that used student laboratory data and/or observations to provide a foundation for the follow-up discussion. Eight of these 11, demonstrated, to a considerable degree, the model approach to instruction. Within this group of 8, four indicated that they utilized the modeled approach prior to the inservice treatment while the remaining 4 showed that they could restructure their courses and reform their teaching behaviors to approach the model profile. While the exploration reported herein did not reveal statistical significance in the teaching behaviors between the PST and LST groups of teachers, these teachers did show significant differences in the amount of time used in conducting post-laboratory

    Pharmaceutical drug development is a complex and lengthy process, requiring excellent project and laboratory management skills. Bioanalysis anchors drug safety and efficacy with systemic and site of action exposures. Development of scientific talent and a willingness to innovate or adopt new technology is essential. Taking unnecessary risks, however, should be avoided. Scientists must strategically assess all risks and find means to minimize or negate them. Laboratory Managers must keep abreast of ever-changing technology. Investments in instrumentation and laboratory design are critical catalysts to efficiency and safety. Matrix management requires regular communication between Project Managers and Laboratory Managers. When properly executed, it aligns the best resources at the right times for a successful outcome. Attention to detail is a critical aspect that separates excellent laboratories. Each assay is unique and requires attention in its development, validation and execution. Methods, training and facilities are the foundation of a bioanalytical laboratory. PMID:24958120

    The Mars Science laboratory (MSL) called Curiosity made a successful landing at Gale crater early August 2012. MSL has an environmental instrument package called the Rover Environmental Monitoring Station (REMS) as a part of its scientific payload. REMS comprises instrumentation for the observation of atmospheric pressure, temperature of the air, ground temperature, wind speed and direction, relative humidity, and UV measurements. The REMS instrument suite is described at length in [1]. We concentrate on describing the first results from the REMS relative humidity observations and comparison of the measurements with modeling results. The REMS humidity device is provided by the Finnish Meteorological Institute. It is based on polymeric capacitive humidity sensors developed by Vaisala Inc. The humidity device makes use of one transducer electronics section placed in the vicinity of the three (3) humidity sensor heads. The humidity device is mounted on the REMS boom 2 providing ventilation with the ambient atmosphere through a filter protecting the device from airborne dust. The absolute accuracy of the humidity device is temperature dependent, and is of the order of 2% at the temperature range of -30 to -10 °C, and of the order of 10% at the temperature range of -80 to -60 °C. This enables the investigations of atmospheric humidity variations of both diurnal and seasonal scale. The humidity device measurements will have a lag, when a step-wise change in humidity is taking place. This lag effect is increasing with decreasing temperature, and it is of the order of a few hours at the temperature of -75 °C. To compensate for the lag effect we used an algorithm developed by Mäkinen [2]. The humidity observations were validated after tedious efforts. This was needed to compensate for the artifacts of the transducer electronics. The compensation process includes an assumption that the relative humidity at Mars in the temperature range of 0 to -30 °C is about zero. The

The REMS instrument suite is described at length in [1]. We concentrate on describing the first results from the REMS pressure observations and comparison of the measurements with modeling results. The REMS pressure device is provided by the Finnish Meteorological Institute. It is based on silicon micro-machined capacitive pressure sensors developed by Vaisala Inc. The pressure device makes use of two transducer electronics sections placed on a single multi-layer PCB inside the REMS Instrument Control Unit (ICU) with a filter-protected ventilation inlet to the ambient atmosphere. The absolute accuracy of the pressure device (< 3 Pa) and zero-drift (< 1 Pa/year) enables the investigations of long term and seasonal cycles of the Martian atmosphere. The relative accuracy, or repeatability, in the diurnal time scale is < 1.5 Pa, less than 2 % of the observed diurnal pressure variation at the landing site. The pressure device has special sensors with very high precision (less than 0.2 Pa) that makes it a good tool to study short-term atmospheric phenomena, e.g., dust devils and other convective vortices. The observed MSL pressure data enable us to study both the long term and short-term phenomena of the Martian atmosphere. This would add knowledge of these phenomena to that gathered by earlier Mars missions and modeling experiments [2,3]. Pressure observations are revealing new information on the local atmosphere and climate at Gale crater, and will shed light on the mesoscale and micrometeorological phenomena.

    2007-10-01

    The Mars Science Laboratory (MSL) rover mission, slated to begin Martian surface operations in 2010, seeks to explore the past and present habitability of a yet-to-be-selected site on Mars. Armed with a suite of instruments capable of spectral, chemical, mineralogical, organic and isotopic analyses, MSL will comprehensively study the Martian atmosphere and rocks and soils on the Martian surface. The Mars Hand Lens Imager (MAHLI), the "geologist's handlens" for MSL, supports habitability studies through aiding the selection of samples for in-depth analysis and placing such samples in a geologic and geomorphic context. More broadly, the goal of MAHLI is to examine the texture, morphology, structure, mineralogy, and stratigraphy of rocks, soils, frost and ice at the microscale. MAHLI will achieve this objective using capabilities new to Martian cameras including a CCD with a Bayer Pattern Filter coupled with a focusable lens. The Bayer Pattern Filter produces RGB color images akin to those taken by the standard commercial digital camera. Placement of MAHLI by the MSL Robotic Arm (RA) at a particular distance from the sample of interest and MAHLI's internal focus mechanism combine to achieve a desired image resolution. At its closest placement (22.5 mm), MAHLI has 9 µm/pixel resolution. In practice, RA placement may be sufficiently uncertain that 9 µm/pixel will not be achieved regularly; however, resolutions in the 12-15 µm/pixel range are expected for typical high resolution images. Depending on the target distance and its surface relief, the target may not be in focus over the entire image. For those cases, MAHLI acquires a series of images taken at a range of focus positions that bracket the location of best focus. MAHLI's onboard software is capable of merging this stack of images, into a single best-focus image. MAHLI can image in natural illumination but it also possesses four, white light emitting diodes (LED) for illumination of samples in shadow or at

    There are three types of sites being considered for deep-underground earth science and physics experiments: (1) abandoned mines (e.g., the Homestake Gold Mine, South Dakota; the Soudan Iron Mine, Minnesota), (2) active mines/facilities (e.g., the Henderson Molybdenum Mine, Colorado; the Kimballton Limestone Mine, Virginia; the Waste Isolation Pilot Plant [in salt], New Mexico), and (3) new tunnels (e.g., Icicle Creek in the Cascades, Washington; Mt. San Jacinto, California). Additional sites have been considered in the geologically unique region of southeastern California and southwestern Nevada, which has both very high mountain peaks and the lowest point in the United States (Death Valley). Telescope Peak (along the western border of Death Valley), Boundary Peak (along the California-Nevada border), Mt. Charleston (outside Las Vegas), and Mt. Tom (along the Pine Creek Valley) all have favorable characteristics for consideration. Telescope Peak can site the deepest laboratory in the United States. The Mt. Charleston tunnel can be a highway extension connecting Las Vegas to Pahrump. The Pine Creek Mine next to Mt. Tom is an abandoned tungsten mine. The lowest levels of the mine are accessible by nearly horizontal tunnels from portals in the mining base camp. Drainage (most noticeable in the springs resulting from snow melt) flows (from the mountain top through upper tunnel complex) out of the access tunnel without the need for pumping. While the underground drifts at Yucca Mountain, Nevada, have not yet been considered (since they are relatively shallow for physics experiments), they have undergone extensive earth science research for nearly 10 years, as the site for future storage of nation's spent nuclear fuels. All these underground sites could accommodate different earth science and physics experiments. Most underground physics experiments require depth to reduce the cosmic-ray-induced muon flux from atmospheric sources. Earth science experiments can be

    Laboratory technicians are a vital part of any working lab. Not only is their knowledge and expertise important for the success of research, but they also often maintain the lab's intellectual and social life. Despite the importance of their work, they are rarely acknowledged in publications, and leave only a few traces within the historical record—the voices of women laboratory technicians are even harder to uncover. This paper attempts to correct this imbalance by presenting the narratives of women who worked as laboratory technicians at places such as the National Institute for Medical Research (NIMR), the Wellcome Research Laboratories, and established hospital and university labs in Cambridge, Oxford and London. The data were collected though narrative interviews. Specifically, the paper looks at the roles of these women within the lab, their experiences of the social and gender dynamics of the lab, and the development of expertise in regard to the work they carried out and the extent to which they received credit for their contributions to science.

    Existing instruments for assessing student or teacher perceptions of characteristics of actual or preferred classroom psychosocial environment are unsuitable for one of the most important settings in science teaching, namely, the science laboratory class. Consequently, the Science Laboratory Environment Inventory (SLEI), was designed to assess student or teacher perceptions of seven scales: Teacher Supportiveness, Student Cohesiveness, Open-Endedness, Integration, Organization, Rule Clarity and Material Environment. An important feature of the design of the study was that the new instrument was field tested simultaneously in six countries: Australia, USA, Canada, England, Nigeria and Israel. This paper is based on a sample of 4643 students in 225 individual laboratory classes, together with the teachers of most of these classes. Preliminary analyses were used to shed light on various important research questions including the differences between Actual and Preferred environments, gender differences in perceptions of Actual and Preferred environment, the relationship between the science laboratory environment and attitude towards science laboratory work, differences between school and university laboratory classes, differences between teachers’ and students’ perceptions of the same laboratory classes, and differences between laboratory classes in different science subjects (Physics, Chemistry, Biology).

    Continuous advances in medical laboratory technology have driven major changes in the practice of laboratory medicine over the past two decades. The importance of the overall quality of a medical laboratory has been ever-increasing in order to improve and ensure the quality and safety of clinical practice by physicians in any type of medical facility. Laboratory physicians and professional staff should challenge themselves more than ever in various ways to cooperate and contribute with practicing physicians for the appropriate utilization of laboratory testing. This will certainly lead to a decrease in inappropriate or unnecessary laboratory testing, resulting in reducing medical costs. In addition, not only postgraduate, but also undergraduate medical education/training systems must be markedly innovated, considering recent rapid progress in electronic information and communication technologies.

    The amount and heterogeneity of data in biomedical research, notably in transnational research, requires new methods for the collection, presentation and analysis of information. Important data from laboratory experiments as well as patient trials are available as images. Thus, the integration and processing of image data represent a crucial component of information systems in biomedical research. The Charité Medical School in Berlin has established a new information service center for kidney diseases and transplantation (Open European Nephrology Science Centre - OpEN.SC) together with the German Research Agency (DFG). The aims of this project are (i) to improve the availability of raw data, (ii) to establish an infrastructure for clinical trials, (iii) to monitor the occurrence of rare disease patterns and (iv) to establish a quality assurance system. Major diagnostic procedures in medicine are based on the processing and analysis of image data. In diagnostic pathology, the availability of automated slide scanners provide the opportunity to digitize entire microscopic slides. The processing, presentation and analysis of these image data are called virtual microscopy. The integration of this new technology into the OpEN.SC system and the link to other heterogeneous data of individual patients represent a major technological challenge. Thus, new ways in communication between clinical and scientific partners have to be established and will be promoted by the project. The technological basis of the repository are web services for a scalable and adaptable system. HL7 and DICOM are considered the main medical standards of communication.

    Since 2003 when the international norm for implementation of quality management in medical laboratories (EN ISO 15189, Medical laboratories--Particular requirements for quality and competence) was established and accepted, accreditation has become practical, generally accepted method of quality management and confirmation of technical competence of medical laboratories in the whole world. This norm has been translated into Croatian and accepted by the Croatian Institute for Norms as Croatian norm. Accreditation is carried out on voluntary basis by the Croatian Accreditation Agency that has up to now accredited two clinical medical biochemical laboratories in the Republic of Croatia. Advantages of accredited laboratory lie in its documented management system, constant improvement and training, reliability of test results, establishing users' trust in laboratory services, test results comparability and interlaboratory (international) test results acceptance by adopting the concept of metrological traceability in laboratory medicine.

    Scientists play a key role in science education: the adventure of making new discoveries excites and motivates students. Yet, American science education test scores lag behind those of other industrial countries, and the call for better science, math and technology education is widespread. Thus, improving American science, math and technological literacy is a major educational goal for the NSF and NASA. Today, funding for research often carries a requirement that the scientist be actively involved in education and public outreach (E/PO) to enhance the science literacy of students, teachers and citizens. How can scientists contribute effectively to E/PO? What roles can scientists take in E/PO? And, how can this be balanced with research requirements and timelines? This talk will focus on these questions, with examples drawn from the author's projects that involve scientists in working with K-12 teacher professional development and with K-12 curriculum development and implementation. Experiences and strategies for teacher professional development in the research environment will be discussed in the context of NASA's airborne astronomy education and outreach projects: the Flight Opportunities for Science Teacher EnRichment project and the future Airborne Ambassadors Program for NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA). Effective partnerships with scientists as content experts in the development of new classroom materials will be described with examples from the SETI Institute's Life in the Universe curriculum series for grades 3-9, and Voyages Through Time, an integrated high school science course. The author and the SETI Institute wish to acknowledge funding as well as scientific and technical support from the National Science Foundation, the National Aeronautics and Space Administration, the Hewlett Packard Company, the Foundation for Microbiology, and the Combined Federated Charities.

    The Homestake Mine in South Dakota ceased gold production in 2002 and was sealed for entry in 2003. The announcement of mine closure triggered the revival of a national initiative to establish a deep underground facility, currently known as the Deep Underground Science and Engineering Laboratory (DUSEL). The National Science Foundation announced that solicitations were to be issued in 2004 and 2005, with the first one (known as S-1) issued in June, 2004. The focus of S-1 is on site non-specific technical requirements to define the scientific program at DUSEL. Earth scientists and physicists participated in an S-1 workshop at Berkeley in August, 2004. This abstract presents the prospects of the Homestake Mine to accommodate the earth science scientific programs defined at the S-1 workshop. The Homestake Mine has hundreds of kilometers of drifts over fifty levels accessible (upon mine reopening) for water evaluation, seepage quantification, seismic monitoring, geophysical imaging, geological mapping, mineral sampling, ecology and geo-microbiology. The extensive network of drifts, ramps, and vertical shafts allows installation of 10-kilometer-scale seismograph and electromagnetic networks. Ramps connecting different levels, typically separated by 150 ft, could be instrumented for flow and transport studies, prior to implementation of coupled thermal-hydro-chemical-mechanical-biological processes testing. Numerous large rooms are available for ecological and introduced-material evaluations. Ideas for installing instruments in cubic kilometers of rock mass can be realized over multiple levels. Environmental assessment, petroleum recovery, carbon sequestration were among the applications discussed in the S-1 workshop. If the Homestake Mine can be expediently reopened, earth scientists are ready to perform important tests with a phased approach. The drifts and ramps directly below the large open pit could be the first area for shallow testing. The 4,850 ft level is the
