Looking for life in all the wrong places - research on cryptoendoliths  

NSDL National Science Digital Library

This article highlights the professional careers of two pioneer microbiologists, Imre Friedmann and his wife Roseli Ocampo-Friedmann. A personal interview with Friedmann gives readers a first hand account of the novel thoughts and discoveries of cryptoendolithic bacteria, or bacteria living within rock. For the past 50 years these two scientists have searched for microbial and algal life among the rocks and sediments of ancient water bodies in deserts, arid polar environments, and other places on earth once thought to be void of all life.

Late-life decline in well-being across adulthood in Germany, the United Kingdom, and the United States: Something is seriously wrong at the end of life.  

PubMed

Throughout adulthood and old age, levels of well-being appear to remain relatively stable. However, evidence is emerging that late in life well-being declines considerably. Using long-term longitudinal data of deceased participants in national samples from Germany, the United Kingdom, and the United States, we examined how long this period lasts. In all 3 nations and across the adult age range, well-being was relatively stable over age but declined rapidly with impending death. Articulating notions of terminal decline associated with impending death, we identified prototypical transition points in each study between 3 and 5 years prior to death, after which normative rates of decline steepened by a factor of 3 or more. The findings suggest that mortality-related mechanisms drive late-life changes in well-being and highlight the need for further refinement of psychological concepts about how and when late-life declines in psychosocial functioning prototypically begin.

Race, Wrongful Conviction & Exoneration

Race, Wrongful Conviction & Exoneration is a sociological examination of the “sociology of punishment” that is a major problem\\u000a in criminological research but almost entirely ignored by sociologists who study and research issues related to crime.

Producing wrong data without doing anything obviously wrong!

This paper presents a surprising result: changing a seemingly innocuous aspect of an experimental setup can cause a systems researcher to draw wrong conclusions from an experiment. What appears to be an innocuous aspect in the experimental setup may in fact introduce a significant bias in an evaluation.

Righting wrongs and reforming rights.  

PubMed

Discusses issues faced by LGBT people, such as a lack of equal civil rights and the need for extra legal and financial protection for families because partners cannot be married. The author notes that, in our society, it is no longer acceptable to be racist, but it is still okay to be homophobic. The many campaigns against gay marriage and efforts in the legislature to prevent change toward equal civil rights and protections are prime examples. In our current political climate, two things are very clear: (a) homophobia is freely tolerated and (b) the times are changing as we inch closer to equal rights every day. We are "righting wrongs and reforming rights." PMID:24684150

The Ultimate Challenge: Prove B. F. Skinner Wrong  

PubMed Central

For much of his career, B. F. Skinner displayed the optimism that is often attributed to behaviorists. With time, however, he became less and less sanguine about the power of behavior science to solve the major problems facing humanity. Near the end of his life he concluded that a fair consideration of principles revealed by the scientific analysis of behavior leads to pessimism about our species. In this article I discuss the case for Skinner's pessimism and suggest that the ultimate challenge for behavior analysts today is to prove Skinner wrong. PMID:22478494

When experiments go wrong: the U.S. perspective.  

PubMed

The view that once prevailed in the U.S.--that research is no more dangerous than the activities of daily life--no longer holds in light of recent experience. Within the past few years, a number of subjects (including normal volunteers) have been seriously injured or killed in research conducted at prestigious institutions. Plainly, when we are talking about research going wrong, we're talking about something very important. We have seen that experiments can go wrong in several ways. Subjects can be injured--physically, mentally, or by having other interests violated. Investigators can commit fraud in data collection or can abuse subjects. And review mechanisms--such as IRBs--don't always work. The two major issues when research goes wrong in any of these ways are, first: What will be done for subjects who have suffered an injury or other wrong? and second: How will future problems be prevented? The present system in the U.S. is better at the second task than the first one. Part of the difficulty in addressing the first lies in knowing what "caused" an apparent injury. Moreover, since until recently the problem of research-related injuries was thought to be a small one, there was considerable resistance to setting up a non-fault compensation system, for fear that it would lead to payment in many cases where such compensation was not deserved. Now, with a further nudge from the NBAC there is renewed interest in developing a formal system to compensate for research injuries. Finally, I have tried to show that our system of local oversight is only partially effective in improving the design of experiments and the consent process in light of "unexpected (adverse) results." As many observers, including the federal General Accounting Office (GAO), have reported, the requirement for "continuing review" of approved research projects is the weak point in the IRB system. The probable solution would be to more strictly apply the requirement that investigators report back any adverse results, de-emphasizing the "screen" introduced by the present language about "unexpected" findings. Yet, despite its weaknesses, there are good aspects to the local basis of our oversight system, and when problems become severe enough, OHRP is likely to evaluate a system and insist on local improvements. Thus, while the U.S. system is far from perfect in responding when research goes wrong, our experience may be useful to others in crafting a system appropriate to their own circumstances. One of the major tasks will be to adequately define what triggers oversight--that is, who reports what to whom and when? The setting of this trigger needs to balance appropriate incentives and penalties. Any system, including our own, will, in my opinion, work much better once an accreditation process is in place, which will offer much more current and detailed information on how each IRB is functioning and what steps are needed to help avoid "experiments going wrong."

What's Wrong with Early Medieval Medicine?  

PubMed Central

The medical writings of early medieval western Europe c. 700 – c. 1000 have often been derided for their disorganised appearance, poor Latin, nebulous conceptual framework, admixtures of magic and folklore, and general lack of those positive features that historians attribute to ancient or later medieval medicine. This paper attempts to rescue the period from its negative image. It examines a number of superficially bizarre writings so as to place them in an intellectual and sociological context, and to suggest that the presumed contrast between them and their ancient and later medieval counterparts has been wrongly drawn.

This article examines the extent to which the three principal exceptions to the common-law doctrine of employment-at-will--namely the public policy, implied contract, and good faith and fair dealing exceptions--have been recognized in hospital termination cases. State supreme court and appellate court cases are analyzed to illustrate the type of conduct that precipitated wrongful termination claims against hospitals during the 1980s, how the courts disposed of these claims, and the rationale underlying their decisions. Suggestions, based on these and related cases, for avoiding or at least minimizing liability for wrongfully terminating hospital employees, are presented. PMID:10108970

Wrongful discharge of the at-will hospital pharmacy employee.

The vast majority of hospital pharmacy employees are not covered by a contract or a collective bargaining agreement and are therefore subject to the employment at-will doctrine. In recent years, there has been considerable erosion of this doctrine with increased protection of the at-will employee from wrongful discharge. This paper reviews both the statutory and judicial limits on the right to discharge an employee at-will, and discusses the implications for pharmacy management and staff. Although the laws relating to wrongful discharge will vary from state to state, the changing theories governing this process are of significant importance to all concerned. PMID:10270315

Textbooks frequently extol plate tectonics theory without questioning what might be wrong with the theory or without discussing a competitive theory.

Along the way, I disclose details of what real science is all about, details all too often absent in textbooks and classroom discussions.

Estrogens in the wrong place at the wrong time: Fetal BPA exposure and mammary cancer.  

PubMed

Iatrogenic gestational exposure to diethylstilbestrol (DES) induced alterations of the genital tract and predisposed individuals to develop clear cell carcinoma of the vagina as well as breast cancer later in life. Gestational exposure of rodents to a related compound, the xenoestrogen bisphenol-A (BPA) increases the propensity to develop mammary cancer during adulthood, long after cessation of exposure. Exposure to BPA during gestation induces morphological alterations in both the stroma and the epithelium of the fetal mammary gland at 18 days of age. We postulate that the primary target of BPA is the fetal stroma, the only mammary tissue expressing estrogen receptors during fetal life. BPA would then alter the reciprocal stroma-epithelial interactions that mediate mammogenesis. In addition to this direct effect on the mammary gland, BPA is postulated to affect the hypothalamus and thus in turn affect the regulation of mammotropic hormones at puberty and beyond.

The harmful, nontherapeutic use of animals in research is morally wrong.  

PubMed

It is argued that using animals in research is morally wrong when the research is nontherapeutic and harmful to the animals. This article discusses methods of moral reasoning and discusses how arguments on this and other bioethical issues might be defended and critiqued. A basic method of moral argument analysis is presented and used to show that common objections to the view that "animal research is morally wrong" fail: ie, common arguments for the view that "animal research is morally permissible" are demonstrably unsound or in need of defense. It is argued that the best explanations why harmful, nontherapeutic research on human beings is wrong, ie, what it is about humans that makes such experimentation wrong, apply to many animals as well. Thus, harmful and nontherapeutic animal experimentation is wrong for reasons similar to the reasons that harmful and nontherapeutic human experimentation is wrong. PMID:21952174

This study analyzes the influence of medical prescriptions' writing on the occurrence of medication errors in the medical wards of five Brazilian hospitals. This descriptive study used data obtained from a multicenter study conducted in 2005. The population was composed of 1,425 medication errors and the sample included 92 routes through which medication was wrongly administered. The pharmacological classes most frequently involved in errors were cardiovascular agents (31.5%), medication that acts on the nervous system (23.9%), and on the digestive system and metabolism (13.0%). In relation to the prescription items that may have contributed to such errors, we verified that 91.3% of prescriptions contained acronyms and abbreviations; patient information was missing in 22.8%, and 4.3% did not include the date and were effaced. Medication wrong-route administrations are common in Brazilian hospitals and around the world. It is well established that these situations may result in severe adverse events for patients, including death. PMID:21412624

Wrongful termination lawsuits: the employers finally win a few.  

PubMed

Much attention has been given of late to the erosion of the "employment-at-will" doctrine. Exceptions to this doctrine began to emerge when courts held that at-will employees could sue if their termination violated public policy. The at-will doctrine was further eroded by court rulings that a contract requiring good cause in order to terminate could be inferred from employee handbooks, company personnel policies, and circumstances of employment. As the initial flood of wrongful termination lawsuits now reaches the appellate level, some guidance on the standards employers must observe can be drawn from court decisions. The authors examine these decisions as well as the legislative reform being proposed in response to them. PMID:10268254

What Was Wrong with Eugenics? Conflicting Narratives and Disputed Interpretations  

NASA Astrophysics Data System (ADS)

Although it is often taken for granted that eugenics is odious, exactly what makes it so is far from obvious. The existence of considerable interpretative flexibility is evident in the disparate policy lessons for contemporary reproductive genetics (or "reprogenetics") that have been derived from essentially the same set of historical facts. In this paper, I will show how different—indeed, diametrically-opposed—morals have been drawn from the history of eugenics and link these contrasting messages both to different underlying conceptions of what constitutes the central wrong of eugenics and differing degrees of enthusiasm for reprogenetic technologies. I will then argue that, for several reasons, the history of eugenics simply cannot provide the kind of direct guidance that many participants in current debates would like. Although the history does have implications for policy, the insights to be gleaned are both subtle and indirect.

Joy to the world! A (healthy) child is born! Reconceptualizing 'harm' in wrongful conception.  

PubMed

The wrongful conception action holds both a troubled past and future. As a response to rapid technological advancement in the area of reproduction, this action has introduced complex legal and ethical issues in the courts' efforts to respond to the question: 'Can parenthood ever constitute an injury?' At the heart of this dilemma lies the manner by which both law and society conceptualize 'harm'--is this 'part of the normal vicissitudes of life' or a harmful event? But this question is not decided within a legal vacuum and public policy factors have deeply influenced the nature and existence of case law in this field. In the context of the controversial cases of McFarlane v Tayside Health Board [2000] and Rees v Darlington Memorial Hospital [2002], this article critically examines how 'harm' is judicially characterized and explores the various tensions emerging from conflicting harm constructs. In arguing that the courts must seek to find a balanced approach between public policy concerns and reproductive autonomy, this article will present a fresh theoretical perspective to the conceptualization of harm based on autonomy as the central organizing principle.

Wrong sign and symmetric limits and non-decoupling in 2HDMs  

NASA Astrophysics Data System (ADS)

We analyse the possibility that, in two Higgs doublet models, one or more of the Higgs couplings to fermions or to gauge bosons change sign, relative to the respective Higgs Standard Model couplings. Possible sign changes in the coupling of a neutral scalar to charged ones are also discussed. These wrong signs can have important physical consequences, manifesting themselves in Higgs production via gluon fusion or Higgs decay into two gluons or into two photons. We consider all possible wrong sign scenarios, and also the symmetric limit, in all possible Yukawa implementations of the two Higgs doublet model, in two different possibilities: the observed Higgs boson is the lightest CP-even scalar, or the heaviest one. We also analyse thoroughly the impact of the currently available LHC data on such scenarios. With all 8 TeV data analysed, all wrong sign scenarios are allowed in all Yukawa types, even at the 1 ? level. However, we will show that B-physics constraints are crucial in excluding the possibility of wrong sign scenarios in the case where tan ? is below 1. We will also discuss the future prospects for probing the wrong sign scenarios at the next LHC run. Finally we will present a scenario where the alignment limit could be excluded due to non-decoupling in the case where the heavy CP-even Higgs is the one discovered at the LHC.

Giant Radio Jet Coming From Wrong Kind of Galaxy  

NASA Astrophysics Data System (ADS)

Giant jets of subatomic particles moving at nearly the speed of light have been found coming from thousands of galaxies across the Universe, but always from elliptical galaxies or galaxies in the process of merging -- until now. Using the combined power of the Hubble Space Telescope, the Very Large Array (VLA) and the 8-meter Gemini-South Telescope, astronomers have discovered a huge jet coming from a spiral galaxy similar to our own Milky Way. Radio-optical view of galaxy Combined HST and VLA image of the galaxy 0313-192. Optical HST image shows the galaxy edge-on; VLA image, shown in red, reveals giant jet of speeding particles. For more images, see this link below. CREDIT: Keel, Ledlow & Owen; STScI,NRAO/AUI/NSF, NASA "We've always thought spirals were the wrong kind of galaxy to generate these huge jets, but now we're going to have to re-think some of our ideas on what produces these jets," said William Keel, a University of Alabama astronomer who led the research team. Keel worked with Michael Ledlow of Gemini Observatory and Frazer Owen of the National Radio Astronomy Observatory. The scientists reported their findings at the American Astronomical Society's meeting in Seattle, Washington. "Further study of this galaxy may provide unique insights on just what needs to happen in a galaxy to produce these powerful jets of particles," Keel said. In addition, Owen said, "The loose-knit nature of the cluster of galaxies in which this galaxy resides may play a part in allowing this particular spiral to produce jets." Astronomers believe such jets originate at the cores of galaxies, where supermassive black holes provide the tremendous gravitational energy to accelerate particles to nearly the speed of light. Magnetic fields twisted tightly by spinning disks of material being sucked into the black hole are presumed to narrow the speeding particles into thin jets, like a nozzle on a garden hose. Both elliptical and spiral galaxies are believed to harbor supermassive black holes at their cores. The discovery that the jet was coming from a spiral galaxy dubbed 0313-192 required using a combination of radio, optical and infrared observations to examine the galaxy and its surroundings. The story began more than 20 years ago, when Owen began a survey of 500 galaxy clusters using the National Science Foundation's then-new VLA to make radio images of the clusters. In the 1990s, Ledlow joined the project, making optical-telescope images of the same clusters as part of his research for a Ph.D dissertation at the University of New Mexico. An optical image from Kitt Peak National Observatory gave a hint that this galaxy, clearly seen with a jet in the VLA images, might be a spiral. Nearly a billion light-years from Earth, 0313-192 proved an elusive target, however. Subsequent observations with the VLA and the 3.5-meter telescope at Apache Point Observatory supported the idea that the galaxy might be a spiral but still were inconclusive. In the Spring of 2002, astronauts installed the Advanced Camera for Surveys on the Hubble Space Telescope. This new facility produced a richly-detailed image of 0313-192, showing that it is a dust-rich spiral seen almost exactly edge-on. "The finely-detailed Hubble image resolved any doubt and proved that this galaxy is a spiral," Ledlow said. Infrared images with the Gemini-South telescope complemented the Hubble images and further confirmed the galaxy's spiral nature. Now, the astronomers seek to understand why this one spiral galaxy, unlike all others seen so far, is producing the bright jets seen with the VLA and other radio telescopes. Several factors may have combined, the researchers feel. "This galaxy's disk is twisted, and that may indicate that it has been disturbed by a close passage of another galaxy or may have swallowed up a companion dwarf galaxy," Keel said. He added, "This galaxy shows signs of having a very massive black hole at its core, and the jets are taking the shortest path out of the galaxy's own gas." Owen points

Correction of target-controlled infusion following wrong selection of emulsion concentrations of propofol  

PubMed Central

Background We investigated the correction methods following wrong-settings of emulsion concentrations of propofol as a countermeasure against erroneous target-controlled infusions (TCI). Methods TCIs were started with targeting 4.0 µg/ml of effect-site concentration (Ceff) of propofol, and the emulsion concentrations were selected for 2.0% instead of 1.0% (FALSE1-2, n = 24), or 1.0% instead of 2.0% (FALSE2-1, n = 24). These wrong TCIs were corrected at 3 min after infusion start. During FALSE1-2, the deficit was filled up while injecting after equilibrium (n = 12), or while overriding (n = 12). During FALSE2-1, the overdose was evacuated while targeting Ceff (n = 12) or targeting plasma concentration (Cp) (n = 12). The gravimetrical measurements of TCI reproduced the Cp and Ceff using simulations. The reproduced Ceff at 3 min (Ceff-3min) and the time to be normalized within ± 5% of target Ceff (T±5%), were compared between the correction methods. Results During the wrong TCI, Ceff-3min was 1.98 ± 0.01 µg/ml in FALSE1-2, and 7.99 ± 0.05 µg/ml in FALSE2-1. In FALSE1-2, T±5% was significantly shorter when corrected while overriding (3.9 ± 0.25 min), than corrected after equilibrium (6.9 ± 0.05 min) (P < 0.001). In FALSE2-1, T±5% was significantly shorter during targeting Cp (3.6 ± 0.04 min) than targeting Ceff (6.7 ± 0.15 min) (P < 0.001). Conclusions The correction methods, based on the pharmacokinetic and pharmacodynamic characteristics, could effectively and rapidly normalize the wrong TCI following erroneously selections of the emulsion concentration of propofol.

Summary Burns are among the most devastating injuries of all and they are responsible for higher hospitalization, morbidity, and mortality rates than other injuries in children. In addition, the management of burns and their sequelae is extremely expensive. Carelessness and wrong behaviours are the main players in burn injuries, especially in children, independently of their socioeconomic level. These burned children pay a costly price. The purpose of this study is to analyse the mechanisms of burn injuries in children in order to highlight the importance of behavioural changes for the reduction of burn injuries in children.

When the need to belong goes wrong: the expression of social anhedonia and social anxiety in daily life.  

PubMed

People possess an innate need to belong that drives social interactions. Aberrations in the need to belong, such as social anhedonia and social anxiety, provide a point of entry for examining this need. The current study used experience-sampling methodology to explore deviations in the need to belong in the daily lives of 245 undergraduates. Eight times daily for a week, personal digital assistants signaled subjects to complete questionnaires regarding affect, thoughts, and behaviors. As predicted, higher levels of social anhedonia were associated with increased time alone, greater preference for solitude, and lower positive affect. Higher social anxiety, in contrast, was associated with higher negative affect and was not associated with increased time alone. Furthermore, greater social anxiety was associated with greater self-consciousness and preference to be alone while interacting with unfamiliar people. Thus, deviations in the need to belong affect social functioning differently depending on whether this need is absent or thwarted. PMID:17760772

Prediction of Potential Wrong-way Entries at Exit Ramps of Signalized Partial Cloverleaf Interchanges.  

PubMed

ABSTRACT Several previous studies, based upon wrong-way driving (WWD) crash history, have demonstrated that partial cloverleaf (parclo) interchanges are more susceptible to WWD movements than others. Currently, there is not a method available to predict WWD incidents and to prioritize parclo interchanges for implementing safety countermeasures for reducing WWD crashes. The focus of this manuscript is to develop a mathematical method to estimate the probability of WWD incidents at exit ramp terminals of this type of interchange. VISSIM traffic simulation models, calibrated by field data, are utilized to estimate the number of potential WWD maneuvers under various traffic volumes on exit ramps and crossroads. The results are helpful for transportation professionals to take proactive steps to identify locations for implementing safety countermeasures at high risk signalized parclo interchanges.

Numerical Dissipation and Wrong Propagation Speed of Discontinuities for Stiff Source Terms  

NASA Technical Reports Server (NTRS)

In compressible turbulent combustion/nonequilibrium flows, the constructions of numerical schemes for (a) stable and accurate simulation of turbulence with strong shocks, and (b) obtaining correct propagation speed of discontinuities for stiff reacting terms on coarse grids share one important ingredient - minimization of numerical dissipation while maintaining numerical stability. Here coarse grids means standard mesh density requirement for accurate simulation of typical non-reacting flows. This dual requirement to achieve both numerical stability and accuracy with zero or minimal use of numerical dissipation is most often conflicting for existing schemes that were designed for non-reacting flows. The goal of this paper is to relate numerical dissipations that are inherited in a selected set of high order shock-capturing schemes with the onset of wrong propagation speed of discontinuities for two representative stiff detonation wave problems.

Earth radiation balance and climate: Why the Moon is the wrong place to observe the Earth  

NASA Astrophysics Data System (ADS)

Increasing 'greenhouse' gases in the Earth's atmosphere will perturb the Earth's radiation balance, forcing climate change over coming decades. Climate sensitivity depends critically on cloud-radiation feedback: its evaluation requires continual observation of changing patterns of Earth radiation balance and cloud cover. The Moon is the wrong place for such observations, with many disadvantages compared to an observation system combining platforms in low polar, intermediate-inclination and geostationary orbits. From the Moon, active observations are infeasible; thermal infrared observations require very large instruments to reach spatial resolutions obtained at much lower cost from geostationary or lower orbits. The Earth's polar zones are never well observed from the Moon; other zones are invisible more than half the time. The monthly illumination cycle leads to further bias in radiation budget determinations. The Earth will be a pretty sight from the Earth-side of the Moon, but serious Earth observations will be made elsewhere.

REDUCTIONS WITHOUT REGRET: AVOIDING WRONG TURNS, ROACH MOTELS, AND BOX CANYONS  

SciTech Connect

This is the third of three papers (in addition to an introductory summary) aimed at providing a framework for evaluating future reductions or modifications of the U.S. nuclear force, first by considering previous instances in which nuclear-force capabilities were eliminated; second by looking forward into at least the foreseeable future at the features of global and regional deterrence (recognizing that new weapon systems currently projected will have expected lifetimes stretching beyond our ability to predict the future); and third by providing examples of past or possible undesirable outcomes in the shaping of the future nuclear force, as well as some closing thoughts for the future. In this paper, we provide one example each of our judgments on what constitutes a box canyon, a roach motel, and a wrong turn: ? Wrong Turn: The Reliable Replacement Warhead ? Roach Motel: SRAM T vs the B61 ? A Possible Box Canyon: A Low-Yield Version of the W76 SLBM Warhead Recognizing that new nuclear missions or weapons are not demanded by current circumstances ? a development path that yields future capabilities similar to those of today, which are adequate if not always ideal, and a broader national-security strategy that supports nonproliferation and arms control by reducing the role for, and numbers, of nuclear weapons ? we briefly consider alternate, less desirable futures, and their possible effect on the complex problem of regional deterrence. In this regard, we discuss the issues posed by, and possible responses to, three example regional deterrence challenges: in-country defensive use of nuclear weapons by an adversary; reassurance of U.S. allies with limited strategic depth threatened by an emergent nuclear power; and extraterritorial, non-strategic offensive use of nuclear weapons by an adversary in support of limited military objectives against a U.S. ally.

How Non-Diagnostic Listening Led to a Rapid “Recovery” from Paranoid Schizophrenia: What is Wrong with Psychiatry?  

Microsoft Academic Search

An experimental interview with a young woman diagnosed with paranoid schizophrenia led to her rapid recovery. This incident and questions raised about psychiatric practices suggest that something is seriously wrong with psychiatry. It lacks insight into its own behavior, invalidates constructive criticism, avoids the kind of selfexamination it urges on “patients,” shows little interest in accounts of successes with “schizophrenic”

Malthus is still wrong: we can feed a world of 9-10 billion, but only by reducing food demand.  

PubMed

In 1798, Thomas Robert Malthus published 'An essay on the principle of population' in which he concluded that: 'The power of population is so superior to the power of the earth to produce subsistence for man, that premature death must in some shape or other visit the human race.' Over the following century he was criticised for underestimating the potential for scientific and technological innovation to provide positive change. Since then, he has been proved wrong, with a number of papers published during the past few decades pointing out why he has been proved wrong so many times. In the present paper, I briefly review the main changes in food production in the past that have allowed us to continue to meet ever growing demand for food, and I examine the possibility of these same innovations delivering food security in the future. On the basis of recent studies, I conclude that technological innovation can no longer be relied upon to prove Malthus wrong as we strive to feed 9-10 billion people by 2050. Unless we are prepared to accept a wide range of significant, undesirable environmental consequences, technology alone cannot provide food security in 2050. Food demand, particularly the demand for livestock products, will need to be managed if we are to continue to prove Malthus wrong into the future. PMID:25319456

Applying fault tree analysis to the prevention of wrong-site surgery.  

PubMed

Wrong-site surgery (WSS) is a rare event that occurs to hundreds of patients each year. Despite national implementation of the Universal Protocol over the past decade, development of effective interventions remains a challenge. We performed a systematic review of the literature reporting root causes of WSS and used the results to perform a fault tree analysis to assess the reliability of the system in preventing WSS and identifying high-priority targets for interventions aimed at reducing WSS. Process components where a single error could result in WSS were labeled with OR gates; process aspects reinforced by verification were labeled with AND gates. The overall redundancy of the system was evaluated based on prevalence of AND gates and OR gates. In total, 37 studies described risk factors for WSS. The fault tree contains 35 faults, most of which fall into five main categories. Despite the Universal Protocol mandating patient verification, surgical site signing, and a brief time-out, a large proportion of the process relies on human transcription and verification. Fault tree analysis provides a standardized perspective of errors or faults within the system of surgical scheduling and site confirmation. It can be adapted by institutions or specialties to lead to more targeted interventions to increase redundancy and reliability within the preoperative process. PMID:25277361

Wrong blood in tube - potential for serious outcomes: can it be prevented?  

PubMed

'Wrong blood in tube' (WBIT) errors, where the blood in the tube is not that of the patient identified on the label, may lead to catastrophic outcomes, such as death from ABO-incompatible red cell transfusion. Transfusion is a multistep, multidisciplinary process in which the human error rate has remained unchanged despite multiple interventions (education, training, competency testing and guidelines). The most effective interventions are probably the introduction of end-to-end electronic systems and a group-check sample for patients about to receive their first transfusion, but neither of these eradicates all errors. Further longer term studies are required with assessment before and after introduction of the intervention. Although most focus has been on WBIT in relation to blood transfusion, all pathology samples should be identified and linked to the correct patient with the same degree of care. Human factors education and training could help to increase awareness of human vulnerability to error, particularly in the medical setting where there are many risk factors. PMID:25284036

What's wrong with executive compensation? A roundtable moderated by Charles Elson.  

PubMed

The value that many superpaid CEO superstars supposedly created has largely disappeared, and the likelihood that it will be recovered anytime soon seems remote. On top of that, a good number of top executives treated their companies like ATMs, awarding themselves millions of dollars in corporate perks. It's hard to dispute the idea that executives were corrupted by the sums of money dangled in front of them. What's wrong with executive compensation, and what can we do about it? HBR and the University of Delaware's Center for Corporate Governance convened a round-table of compensation experts last October on the university's campus in Newark, Delaware. The 12 panelists, from CEOs to investors, from the professionals who advise them to a chief justice who rules on their disputes, provided an extraordinary diversity of viewpoints. The panelist began by debating ways to align the interests of the senior executives with the long-term interests of the company-weighing the relative benefits of stock options versus stock grants, for instance. But the discussion expanded to cover broader questions of corporate governance and company values. "The main reason compensation increases every year is that most boards want their CEO to be in the top half of the CEO peer group," said Ed Woolard,Jr., a former CEO of DuPont. And compensation lawyer Joe Bachelder pointed out the danger of structuring pay in such a way that it dampens risk taking among executives. It was a lively and wide-ranging discussion of one business's most pressing issues. PMID:12545924

Knowing Right From Wrong In Mental Arithmetic Judgments: Calibration Of Confidence Predicts The Development Of Accuracy  

PubMed Central

Does knowing when mental arithmetic judgments are right—and when they are wrong—lead to more accurate judgments over time? We hypothesize that the successful detection of errors (and avoidance of false alarms) may contribute to the development of mental arithmetic performance. Insight into error detection abilities can be gained by examining the “calibration” of mental arithmetic judgments—that is, the alignment between confidence in judgments and the accuracy of those judgments. Calibration may be viewed as a measure of metacognitive monitoring ability. We conducted a developmental longitudinal investigation of the relationship between the calibration of children's mental arithmetic judgments and their performance on a mental arithmetic task. Annually between Grades 5 and 8, children completed a problem verification task in which they rapidly judged the accuracy of arithmetic expressions (e.g., 25+50?=?75) and rated their confidence in each judgment. Results showed that calibration was strongly related to concurrent mental arithmetic performance, that calibration continued to develop even as mental arithmetic accuracy approached ceiling, that poor calibration distinguished children with mathematics learning disability from both low and typically achieving children, and that better calibration in Grade 5 predicted larger gains in mental arithmetic accuracy between Grades 5 and 8. We propose that good calibration supports the implementation of cognitive control, leading to long-term improvement in mental arithmetic accuracy. Because mental arithmetic “fluency” is critical for higher-level mathematics competence, calibration of confidence in mental arithmetic judgments may represent a novel and important developmental predictor of future mathematics performance.

On a per capita basis, Australia spent more than seven times as much on its Sydney Olympic team as did Canada, to win four times as many medals. Compared with Australia, Canada spent an additional amount per capita (standardised to the purchasing power parity rate at year 2000) of US dollars 1605 per life-year gained on healthcare in 2000. Neither country is "right" or "wrong" in making these funding choices, but they highlight the need for more explicit discussion about what is being spent, what is obtained for the given expenditure and what society actually values.

Chiroptical signatures of life and fundamental physics.  

PubMed

This paper aims to inspire experimentalists to carry out proposed new chiroptical experiments springing from the theoretical study of the role of parity violation in the origin of biomolecular homochirality and to provide a brief update on the current status of calculations of the electroweak parity-violating energy difference (PVED) between enantiomers. If the PVED did select life's handedness, we would expect to find life on other planets consistently using the same hand as terrestrial biochemistry. Much more importantly, even finding the "wrong" hand (rather than a racemic mixture) on another planet could be the homochiral signature of life, and we discuss our proposal for chiroptical detection of life on extra-solar planets. The PVED may also have an exciting future as a "molecular footprint" of fundamental physics: comparison of calculated PVEDs with measured values could one day allow chemists to do "table-top particle physics" more cheaply with improved chiroptical techniques instead of ever larger particle accelerators. We discuss our proposed chiroptical method to measure the PVED by using molecular beams. To our knowledge, optical rotation has not yet been measured in molecular beams, but the rewards of doing so include a host of other "first ever" results in addition to measurement of the PVED.

Defining Life  

PubMed Central

Abstract Any definition is intricately connected to a theory that gives it meaning. Accordingly, this article discusses various definitions of life held in the astrobiology community by considering their connected “theories of life.” These include certain “list” definitions and a popular definition that holds that life is a “self-sustaining chemical system capable of Darwinian evolution.” We then act as “anthropologists,” studying what scientists do to determine which definition-theories of life they constructively hold as they design missions to seek non-terran life. We also look at how constructive beliefs about biosignatures change as observational data accumulate. And we consider how a definition centered on Darwinian evolution might itself be forced to change as supra-Darwinian species emerge, including in our descendents, and consider the chances of our encountering supra-Darwinian species in our exploration of the Cosmos. Last, we ask what chemical structures might support Darwinian evolution universally; these structures might be universal biosignatures. Key Words: Evolution—Life—Life detection—Biosignatures.

What Went Wrong (and Right) in my Research for Undergraduates Program this Summer  

NASA Astrophysics Data System (ADS)

The Research Experience for Undergraduates Site on Sustainable Land and Water Resources (NSF GEO-055346) is a complicated affair (like many REUs) with research teams on site on two different Native American reservations (the Fond du Lac Band of Lake Superior Chippewa Reservation, Minnesota, and the Flathead Indian Reservation of the Confederated Salish and Kootenai Tribes, Montana), mentors from 2 universities and 2 reservations, and diverse participants from across the country. Students are diverse in ethnicity, academic majors, institution type, age, and life situation, with many nontraditional students as participants. While this all adds up to an interesting and exciting program, it is not without challenges. Herein the program directors discuss some of the particular challenges faced this summer, feedback the outside evaluation specialist received from participants and mentors, and ways the program's mentor team might respond in the future. This discussion will include a look at how systemic changes to an REU can lead to positive change, including a review of the recruiting and application process, communication between and among mentors and participants, the team structure of the REU, and supports in place to lead to participant success. Also included will be a discussion of how the relationship between the Native American reservations and the academic institutions was developed and how we continue to evolve based on annual feedback from all participants.

Hospital Medicine (Part 1): what is wrong with acute hospital care?  

PubMed

Modern hospitals are facing several challenges and, over the last decade in particular, many of these institutions have become dysfunctional. Paradoxically as medicine has become more successful the demand for acute hospital care has increased, yet there is no consensus on what conditions or complaints require hospital admission and there is wide variation in the mortality rates, length of stay and possibly standards of care between different units. Most acutely ill patients are elderly and instead of one straightforward diagnosis are more likely to have a complex combination of multiple co-morbid conditions. Any elderly patient admitted to hospital is at considerable risk which must be balanced against the possible benefits. Although most of the patients in hospital die from only approximately ten diagnoses, obvious life saving treatment is often delayed by a junior doctor in-training first performing an exhaustive complete history and physical, and then ordering a number of investigations before consulting a senior colleague. Following this traditional hierarchy delays care with several "futile cycles" of clinical activity thoughtlessly directed at the patient without any benefit being delivered. If acute hospital medicine is to be improved changes in traditional assumptions, attitudes, beliefs and practices are needed. PMID:19712844

The evolution of human adiposity and obesity: where did it all go wrong?  

PubMed Central

Because obesity is associated with diverse chronic diseases, little attention has been directed to the multiple beneficial functions of adipose tissue. Adipose tissue not only provides energy for growth, reproduction and immune function, but also secretes and receives diverse signaling molecules that coordinate energy allocation between these functions in response to ecological conditions. Importantly, many relevant ecological cues act on growth and physique, with adiposity responding as a counterbalancing risk management strategy. The large number of individual alleles associated with adipose tissue illustrates its integration with diverse metabolic pathways. However, phenotypic variation in age, sex, ethnicity and social status is further associated with different strategies for storing and using energy. Adiposity therefore represents a key means of phenotypic flexibility within and across generations, enabling a coherent life-history strategy in the face of ecological stochasticity. The sensitivity of numerous metabolic pathways to ecological cues makes our species vulnerable to manipulative globalized economic forces. The aim of this article is to understand how human adipose tissue biology interacts with modern environmental pressures to generate excess weight gain and obesity. The disease component of obesity might lie not in adipose tissue itself, but in its perturbation by our modern industrialized niche. Efforts to combat obesity could be more effective if they prioritized ‘external’ environmental change rather than attempting to manipulate ‘internal’ biology through pharmaceutical or behavioral means.

LIFE, Life Investigation For Enceladus  

NASA Astrophysics Data System (ADS)

Enceladus, a small icy moon of Saturn, is one of NASA outer planet life search targets and unique in its current active jets. As with comets, this enables a low-cost flyby sample return mission like STARDUST. Samples from Enceladus will expand our in-depth knowledge of "life” and allow us to effectively plan for future missions. Cassini found Enceladus’ jets composed of fine icy particules and hydrocarbons. Saturn's E ring is sustained by these jets for at least the last 300 years. Clearly there is a subsurface heat source generating such jets. Several theories for the origin of life on Earth would also apply to Enceladus; thus, obtaining the samples from the plume will provide breakthrough understandings of the nature of current or past life markers. The highly detailed analyses of Apollo and STARDUST samples revolutionized our knowledge of the Moon and comets and provided fundamental insights into remarkable processes that occur early in the formation of the Solar System. These in-depth analyses are not possible with astronomical remote sensing or in-situ instrumentations. Since the duration of these plumes is unknown, it is imperative to capture these samples by the earliest flight opportunity- the Discovery AO by the fall of 2009. For LIFE, we have a trajectory to encounter the plume at less than 4 km/s ensuring a more gentle capture of organics than STARDUST at 6 km/s. With less than 14-year mission duration, the samples can be returned to Earth before 2029. By capitalizing on the STARDUST heritage of design-to-cost mindset, the mission cost can be controlled. For cost reduction, the upcoming Discovery AO offers unique free ASRGs and allows the use of Jupiter for gravity assist.

From Sakata Model to Goldberg-Ne'eman Quarks and Nambu QCD Phenomenology and ``Right" and ``Wrong" Experiments  

NASA Astrophysics Data System (ADS)

The basic theoretical milestones were the Sakata SU(3) symmetry, theGoldberg-Ne'eman composite model with SU(3) triplets having baryon number (1/3) and the Nambu color gauge Lagrangian. The transition was led in right and wrong directions by experiments interpreted by phenomenology. A ``good" experiment on bar{p}p annihilation at rest showed that the Sakata model predictions disagreed with experiment. A ``bad" experiment prevented the use of the Goldberg-Ne'eman triplet model to predict the existence and masses of the Xi(*) and Omega(-) . More ``good" experiments revealed the existence and mass of the Xi(*) and the Omega(-) and the absence of positive strangeness baryon resonances, thus confirming the ``tenfold way". Further ``good experiments" revealed the existence of the vector meson nonet, SU(3) breaking with singlet-octet mixing and the suppression of the phi -> rho pi decay. These led to the quark triplet model. The paradox of peculiar statistics then arose as the Delta(++) and Omega(-) contained three identical spin-1/2 fermions coupled symmetrically to spin (3/2). This led to color and the Nambu QCD. The book ``Lie Groups for Pedestrians" used the Sakata model with the name ``sakaton" for the pnLambda triplet to teach the algebra of SU(3) to particle physicists in the U.S. and Europe who knew no group theory. The Sakata model had a renaissance in hypernuclear physics in the 1970's.

Personalization of health care in England: have the wrong lessons been drawn from the personal health budget pilots?  

PubMed

The Government has introduced personal health budgets in England's National Health Service (NHS). A three-year programme of pilots has shown that personal health budgets have improved outcomes and are generally cost-effective. They are seen as a key step toward creating a personalized service. However, the Government is attributing the success of the pilots to entirely the wrong factors. It believes that a process similar to the one introduced in social care - where it is called self-directed support - based on the person being given a sum of money 'up-front' with which to plan their own care - is responsible for the better outcomes. However, this is not supported by the evidence from the pilots which points to quite different factors being at play. The consequences are potentially very serious. The success of the pilots will not be repeated in roll out. Further, there is the potential to greatly weaken the service by creating confused process and practice, and additional dysfunctional bureaucracy. The practice and process implications from a correct reading of the reasons for success within the pilots centre on replacing the consumerist concepts underpinning self-directed support with what we have called 'flexibility through partnership'. This will require freeing up the resource base as cash and creating a policy framework to enable decisions about how much resource each person should get within a cash-limited budget that will almost certainly be less than would be required to meet all assessed need.

Statistical mechanics of the genetic code: a glimpse of early life?  

NASA Astrophysics Data System (ADS)

Relics of early life, preceding even the last universal common ancestor of all life on Earth, are present in the structure of the modern day canonical genetic code --- the map between DNA sequence and amino acids that form proteins. The code is not random, as often assumed, but instead is now known to have certain error minimisation properties. How could such a code evolve, when it would seem that mutations to the code itself would cause the wrong proteins to be translated, thus killing the organism? I show how a unique and optimal genetic code can emerge over evolutionary time from digital life simulations, but only if horizontal gene transfer was a much stronger characteristic of early life than it is now. These results suggest a natural scenario in which evolution exhibits three distinct dynamical regimes, differentiated respectively by the way in which information flow, genetic novelty and complexity emerge. Possible observational signatures of these predictions are discussed.

Planetary Environments for Life  

NASA Technical Reports Server (NTRS)

One of the most interesting phenomenon associated with planets is life. In this paper I consider how life on Earth, and in particular life in extreme environments on Earth, define the range of environmental conditions for life, From this we can speculate on how life that is similar to life on Earth might survive on other worlds. Finally the possibility that life in some other planetary environments may have to be fundamental different from life on Earth to exist is considered.

'Wrong-way-round ionization' and screening for doping substances in human urine by high-performance liquid chromatography/orbitrap mass spectrometry.  

PubMed

To free analytical resources for new classes of doping substances, such as banned proteins, maximization of the number of compounds that can be determined with high sensitivity in a single run is highly urgent. This study demonstrates an application of 'wrong-way-round ionization' for the simultaneous detection of multiple classes of doping substances without the need to switch the polarity. A screening method for the detection of 137 compounds from various classes of prohibited substances (stimulants, diuretics, ?(2)-agonists, ?-blockers, antiestrogens, glucocorticosteroids and anabolic agents) has been developed. The method involves an enzymatic hydrolysis, liquid-liquid extraction and detection by liquid chromatography/orbitrap mass spectrometry with wrong-way-round ionization. Up to 64% of compounds had a 10-fold lower limit of detection (LOD) than the minimum required performance limit. To compare the efficiency of conventional ionization relative to wrong-way-round ionization of doping substances in?+?ESI, a fortified blank urine sample at the minimum required performance limit was analyzed using two ESI approaches. All compounds were detected with markedly better S/N in a high-pH mobile phase, with the exception of acetazolamide (minimal change in S/N, < 20%).The method was validated by spiking 10 different blank urine samples at five different concentrations. Validation parameters included the LOD, selectivity, ion suppression, extraction recovery and repeatability. PMID:22431466

The accident at TEPCO's Fukushima-Daiichi Nuclear Power Station: What went wrong and what lessons are universal?  

NASA Astrophysics Data System (ADS)

After a short summary of the nuclear accident at the Fukushima Daiichi Nuclear Power Station, this paper discusses “what went wrong” by illustrating the problems of the specific layers of defense-in-depth (basic strategy for assuring nuclear safety) and “what lessons are universal.” Breaches in the multiple layers of defense were particularly significant in respective protection (a) against natural disasters (first layer of defense) as well as (b) against severe conditions, specifically in this case, a complete loss of AC/DC power and isolation from the primary heat sink (fourth layer of defense). Confusion in crisis management by the government and insufficient implementation of offsite emergency plans revealed problems in the fifth layer of defense. By taking into consideration managerial and safety culture that might have relevance to this accident, in the author's view, universal lessons are as follows: Resilience: the need to enhance organizational capabilities to respond, monitor, anticipate, and learn in changing conditions, especially to prepare for the unexpected. This includes increasing distance to cliff edge by knowing where it exists and how to increase safety margin. Responsibility: the operator is primarily responsible for safety, and the government is responsible for protecting public health and environment. For both, their right decisions are supported by competence, knowledge, and an understanding of the technology, as well as humble attitudes toward the limitations of what we know and what we can learn from others. Social license to operate: the need to avoid, as much as possible regardless of its probability of occurrence, the reasonably anticipated environmental impact (such as land contamination), as well as to build public confidence/trust and a renewed liability scheme.

Queuing the Wrong U?  

NASA Astrophysics Data System (ADS)

Just as there are many different types of uncertainty, there are many different types of models. The best technique for quantifying and communicating uncertainty will depend on the nature of that uncertainty: is it mere imprecision in a well-defined number (as with the square-root of two), intractability (as when we know how to compute the answer, but have not yet been able to carry out the calculation), indeterminacy (as when there is no well-defined target about which to be imprecise) or other. The relevance of UQ to a decision maker or scientist will also depend on the type of quantitative model that is considered: is the model intended to explain, or to forecast, or to provide a quantitative analysis of the past? When a perfect model is available, many of these distinctions collapse. In practice, attempting to quantify one type of uncertainty via a model which may not even display that kind of uncertainty is a nonsense. One must be careful not to confuse the diversity of our models for the uncertainty in our future. Or a well-defined probability forecast for what the next model simulation will report, with a probability forecast for the world. How is UQ to recognize the line between sensitivity analysis and probability forecasting? These questions will be addressed in the context of climate science, and more broadly that of science in support of decision making. The ways and means of UQ are shown to vary with type of model considered, the extent to which that model class is deemed adequate for purpose in a specific application, and whether or not the relevant dominant uncertainty (known from the science, but perhaps absent from the models) has been considered. Uncertainty Quantification may prove to be a very wide field, extending well beyond the bounds of the probability calculus.

All models are wrong.  

PubMed

As the field of phylogeography has continued to move in the model-based direction, researchers continue struggling to construct useful models for inference. These models must be both simple enough to be tractable yet contain enough of the complexity of the natural world to make meaningful inference. Beyond constructing such models for inference, researchers explore model space and test competing models with the data on hand, with the goal of improving the understanding of the natural world and the processes underlying natural biological communities. Approximate Bayesian computation (ABC) has increased in recent popularity as a tool for evaluating alternative historical demographic models given population genetic samples. As a thorough demonstration, Pelletier & Carstens (2014) use ABC to test 143 phylogeographic submodels given geographically widespread genetic samples from the salamander species Plethodon idahoensis (Carstens et al. 2014) and, in so doing, demonstrate how the results of the ABC model choice procedure are dependent on the model set one chooses to evaluate.

The rights and wrongs of blood-brain barrier permeability studies: a walk through 100 years of history  

PubMed Central

Careful examination of relevant literature shows that many of the most cherished concepts of the blood-brain barrier are incorrect. These include an almost mythological belief in its immaturity that is unfortunately often equated with absence or at least leakiness in the embryo and fetus. The original concept of a blood-brain barrier is often attributed to Ehrlich; however, he did not accept that permeability of cerebral vessels was different from other organs. Goldmann is often credited with the first experiments showing dye (trypan blue) exclusion from the brain when injected systemically, but not when injected directly into it. Rarely cited are earlier experiments of Bouffard and of Franke who showed methylene blue and trypan red stained all tissues except the brain. The term “blood-brain barrier” “Blut-Hirnschranke” is often attributed to Lewandowsky, but it does not appear in his papers. The first person to use this term seems to be Stern in the early 1920s. Studies in embryos by Stern and colleagues, Weed and Wislocki showed results similar to those in adult animals. These were well-conducted experiments made a century ago, thus the persistence of a belief in barrier immaturity is puzzling. As discussed in this review, evidence for this belief, is of poor experimental quality, often misinterpreted and often not properly cited. The functional state of blood-brain barrier mechanisms in the fetus is an important biological phenomenon with implications for normal brain development. It is also important for clinicians to have proper evidence on which to advise pregnant women who may need to take medications for serious medical conditions. Beliefs in immaturity of the blood-brain barrier have held the field back for decades. Their history illustrates the importance of taking account of all the evidence and assessing its quality, rather than selecting papers that supports a preconceived notion or intuitive belief. This review attempts to right the wrongs. Based on careful translation of original papers, some published a century ago, as well as providing discussion of studies claiming to show barrier immaturity, we hope that readers will have evidence on which to base their own conclusions.

Could some people be wronged by contracting swine flu? A case discussion on the links between the farm animal sector and human disease.  

PubMed

This paper uses the imaginary case of Gemma, presented initially at the International Swine Flu Conference (London, March 2010), to discuss whether a nurse who disagrees with most ways in which animals are farmed would be wronged if she contracted swine flu. It is argued that the farm animal sector has contributed to the emergence of H1N1 flu, and that the sector in general contributes significantly to the burden of human disease. The aim of this paper is to promote debate on the question as to whether a range of systems used by the farm animal sector survive moral scrutiny in light of these concerns. PMID:21292701

Can the surgical checklist reduce the risk of wrong site surgery in orthopaedics? - can the checklist help? Supporting evidence from analysis of a national patient incident reporting system  

PubMed Central

Background Surgical procedures are now very common, with estimates ranging from 4% of the general population having an operation per annum in economically-developing countries; this rising to 8% in economically-developed countries. Whilst these surgical procedures typically result in considerable improvements to health outcomes, it is increasingly appreciated that surgery is a high risk industry. Tools developed in the aviation industry are beginning to be used to minimise the risk of errors in surgery. One such tool is the World Health Organization's (WHO) surgery checklist. The National Patient Safety Agency (NPSA) manages the largest database of patient safety incidents (PSIs) in the world, already having received over three million reports of episodes of care that could or did result in iatrogenic harm. The aim of this study was to estimate how many incidents of wrong site surgery in orthopaedics that have been reported to the NPSA could have been prevented by the WHO surgical checklist. Methods The National Reporting and Learning Service (NRLS) database was searched between 1st January 2008- 31st December 2008 to identify all incidents classified as wrong site surgery in orthopaedics. These incidents were broken down into the different types of wrong site surgery. A Likert-scale from 1-5 was used to assess the preventability of these cases if the checklist was used. Results 133/316 (42%) incidents satisfied the inclusion criteria. A large proportion of cases, 183/316 were misclassified. Furthermore, there were fewer cases of actual harm [9% (12/133)] versus 'near-misses' [121/133 (91%)]. Subsequent analysis revealed a smaller proportion of 'near-misses' being prevented by the checklist than the proportion of incidents that resulted in actual harm; 18/121 [14.9% (95% CI 8.5 - 21.2%)] versus 10/12 [83.3% (95%CI 62.2 - 104.4%)] respectively. Summatively, the checklist could have been prevented 28/133 [21.1% (95%CI 14.1 - 28.0%)] patient safety incidents. Discussion Orthopaedic surgery is a high volume specialty with major technical complexity in terms of equipment demands and staff training and familiarity. There is therefore an increased propensity for errors to occur. Wrong-site surgery still occurs in this specialty and is a potentially devastating situation for both the patient and surgeon. Despite the limitations of inclusion and reporting bias, our study highlights the need to match technical precision with patient safety. Tools such as the WHO surgical checklist can help us to achieve this. PMID:21501466

Automatic localization of vertebral levels in x-ray fluoroscopy using 3D-2D registration: a tool to reduce wrong-site surgery  

NASA Astrophysics Data System (ADS)

Surgical targeting of the incorrect vertebral level (wrong-level surgery) is among the more common wrong-site surgical errors, attributed primarily to the lack of uniquely identifiable radiographic landmarks in the mid-thoracic spine. The conventional localization method involves manual counting of vertebral bodies under fluoroscopy, is prone to human error and carries additional time and dose. We propose an image registration and visualization system (referred to as LevelCheck), for decision support in spine surgery by automatically labeling vertebral levels in fluoroscopy using a GPU-accelerated, intensity-based 3D-2D (namely CT-to-fluoroscopy) registration. A gradient information (GI) similarity metric and a CMA-ES optimizer were chosen due to their robustness and inherent suitability for parallelization. Simulation studies involved ten patient CT datasets from which 50?000 simulated fluoroscopic images were generated from C-arm poses selected to approximate the C-arm operator and positioning variability. Physical experiments used an anthropomorphic chest phantom imaged under real fluoroscopy. The registration accuracy was evaluated as the mean projection distance (mPD) between the estimated and true center of vertebral levels. Trials were defined as successful if the estimated position was within the projection of the vertebral body (namely mPD <5 mm). Simulation studies showed a success rate of 99.998% (1 failure in 50?000 trials) and computation time of 4.7 s on a midrange GPU. Analysis of failure modes identified cases of false local optima in the search space arising from longitudinal periodicity in vertebral structures. Physical experiments demonstrated the robustness of the algorithm against quantum noise and x-ray scatter. The ability to automatically localize target anatomy in fluoroscopy in near-real-time could be valuable in reducing the occurrence of wrong-site surgery while helping to reduce radiation exposure. The method is applicable beyond the specific case of vertebral labeling, since any structure defined in pre-operative (or intra-operative) CT or cone-beam CT can be automatically registered to the fluoroscopic scene.

How Many Times Can You Be Wrong and Still Be Right? T. H. Morgan, Evolution, Chromosomes and the Origins of Modern Genetics

Science textbooks and classes mostly emphasize what are considered by today's standards the "right" or "correct" interpretations of particular phenomena or processes. When "incorrect" ideas of the past are mentioned at all, it is simply to point out their errors, with little attention as to why the ideas were put forward in the first place, or ever gained a following. A strong case can be made, however, for presenting contrasting or even what are considered today "wrong" hypotheses as a way of not only emphasizing the dynamic nature of science (which is punctuated throughout by controversies and contrasting views), but also as a way of helping students better understand the details and workings of contemporary views.

Compliance with a time-out procedure intended to prevent wrong surgery in hospitals: results of a national patient safety programme in the Netherlands  

PubMed Central

Objective To prevent wrong surgery, the WHO ‘Safe Surgery Checklist’ was introduced in 2008. The checklist comprises a time-out procedure (TOP): the final step before the start of the surgical procedure where the patient, surgical procedure and side/site are reviewed by the surgical team. The aim of this study is to evaluate the extent to which hospitals carry out the TOP before anaesthesia in the operating room, whether compliance has changed over time, and to determine factors that are associated with compliance. Design Evaluation study involving observations. Setting Operating rooms of 2 academic, 4 teaching and 12 general Dutch hospitals. Participants A random selection was made from all adult patients scheduled for elective surgery on the day of the observation, preferably involving different surgeons and different procedures. Results Mean compliance with the TOP was 71.3%. Large differences between hospitals were observed. No linear trend was found in compliance during the study period. Compliance at general and teaching hospitals was higher than at academic hospitals. Compliance decreased with the age of the patient, general surgery showed lower compliance in comparison with other specialties and compliance was higher when the team was focused on the TOP. Conclusions Large differences in compliance with the TOP were observed between participating hospitals which can be attributed at least in part to the type of hospital, surgical specialty and patient characteristics. Hospitals do not comply consistently with national guidelines to prevent wrong surgery and further implementation as well as further research into non-compliance is needed. PMID:24993761

Due to the radiosensitivity of the lung, toxic endpoints, in the form of radiation pneumonitis and pulmonary fibrosis, are relatively frequent outcomes following radiation treatment of thoracic neoplasms. Because of the potential lethal nature of these normal tissue reactions, they not only lead to quality-of-life issues in survivors, but also are deemed dose-limiting and thereby compromise treatment. The mitigation and treatment of lung normal tissue late effects has therefore been the goal of many investigations; however, the complexity of both the organ itself and its response to injury has resulted in little success. Nonetheless, current technology allows us to propose likely targets that are either currently being researched or should be considered in future studies. PMID:20583979

Defending Definitions of Life.  

PubMed

Abstract Over the past 10 years, it has become unpopular to talk about definitions of life, under the assumption that attempts at a precise definition are counterproductive. Recent attempts have failed to meet strict philosophical criteria for definitions and have failed to reach consensus. I argue that provisional definitions are necessary for clear communications. Our current knowledge of biology justifies a number of universal claims about the category of life. Whether or not "life" represents a natural category, it maps to a number of important, observable processes. Given the importance of those processes and the extent of our knowledge, plural explicit definitions of life (and related categories) will be necessary for progress in astrobiology and origin-of-life studies as well as biology in general. I propose concrete categories related to, but not necessarily coextensive with, life for clear communication and hypothesis formation: Woese life, Darwin life, Haldane life.

Life in Extreme Environments  

NASA Technical Reports Server (NTRS)

Although the Viking results may indicate that Mars has no life today, there is direct geomorphological evidence that, in the past, Mars had large amounts of liquid water on its surface - possibly due to a thicker atmosphere. From a biological perspective the existence of liquid water, by itself motivates the question of the origin of life on Mars. One of the martian meteorites dates back to this early period and may contain evidence consistent with life. From studies of the Earth's earliest biosphere we know that by 3.5 Gyr. ago, life had originated on Earth and reached a fair degree of biological sophistication. Surface activity and erosion on Earth make it difficult to trace the history of life before the 3.5 Gyr timeframe. Ecosystems in cold, dry locations on Earth - such as the Antarctic - provide examples of how life on Mars might have survived and where to look for fossils.

Searching for Life  

NSDL National Science Digital Library

This is an activity designed to develop a working definition of life. Learners will conduct a simple experiment, looking for signs of life in three different "soil" samples. The experiment introduces children to the difficulty that scientists face in defining life. By observing the soil samples, participants try to determine if any contain signs of life and work to identify, refine, and create a set of characteristics that may be used to identify living versus nonliving things. The activity concludes with the development of a group definition of life. This group definition will be referred to in subsequent activities. It also includes specific tips within each activity for effectively engaging girls in STEM. This is activity 1 in Explore: Life on Mars? that was developed specifically for use in libraries.

Questions of the suitability of other planets in the solar system for terrestrial organisms are discussed. It is found that life forms similar to terrestrial organisms but modified to fit the prevailing conditions could exist on Venus, Mars, and Jupiter. Of these, only in the case of Jupiter is there any evidence that life would have been able to evolve. Life on Jupiter would be restricted to the clouds. It is pointed out that life may have developed on other celestial bodies in forms which are quite dissimilar to terrestrial organisms with regard to their biochemistry.

Thermostable Shelf Life Study  

NASA Technical Reports Server (NTRS)

The objective of this project is to determine the shelf life end-point of various food items by means of actual measurement or mathematical projection. The primary goal of the Advanced Food Technology Project in these long duration exploratory missions is to provide the crew with a palatable, nutritious and safe food system while minimizing volume, mass, and waste. The Mars missions could be as long as 2.5 years with the potential of the food being positioned prior to the crew arrival. Therefore, it is anticipated that foods that are used during the Mars missions will require a 5 year shelf life. Shelf life criteria are safety, nutrition, and acceptability. Any of these criteria can be the limiting factor in determining the food's shelf life. Due to the heat sterilization process used for the thermostabilized food items, safety will be preserved as long as the integrity of the package is maintained. Nutrition and acceptability will change over time. Since the food can be the sole source of nutrition to the crew, a significant loss in nutrition may determine when the shelf life endpoint has occurred. Shelf life can be defined when the food item is no longer acceptable. Acceptability can be defined in terms of appearance, flavor, texture, or aroma. Results from shelf life studies of the thermostabilized food items suggest that the shelf life of the foods range from 0 months to 8 years, depending on formulation.

Is Life Unique?  

PubMed Central

Is life physicochemically unique? No. Is life unique? Yes. Life manifests innumerable formalisms that cannot be generated or explained by physicodynamics alone. Life pursues thousands of biofunctional goals, not the least of which is staying alive. Neither physicodynamics, nor evolution, pursue goals. Life is largely directed by linear digital programming and by the Prescriptive Information (PI) instantiated particularly into physicodynamically indeterminate nucleotide sequencing. Epigenomic controls only compound the sophistication of these formalisms. Life employs representationalism through the use of symbol systems. Life manifests autonomy, homeostasis far from equilibrium in the harshest of environments, positive and negative feedback mechanisms, prevention and correction of its own errors, and organization of its components into Sustained Functional Systems (SFS). Chance and necessity—heat agitation and the cause-and-effect determinism of nature’s orderliness—cannot spawn formalisms such as mathematics, language, symbol systems, coding, decoding, logic, organization (not to be confused with mere self-ordering), integration of circuits, computational success, and the pursuit of functionality. All of these characteristics of life are formal, not physical. PMID:25382119

Life in Extreme Environments  

NASA Technical Reports Server (NTRS)

Each recent report of liquid water existing elsewhere in the solar system has reverberated through the international press and excited the imagination of humankind. Why? Because in the last few decades we have come to realize that where there is liquid water on Earth, virtually no matter what the physical conditions, there is life. What we previously thought of as insurmountable physical and chemical barriers to life, we now see as yet another niche harboring 'extremophiles'. This realization, coupled with new data on the survival of microbes in the space environment and modeling of the potential for transfer of life between celestial bodies, suggests that life could be more common than previously thought. Here we critically examine what it means to be an extremophile, the implications of this for evolution, biotechnology, and especially the search for life in the cosmos.

Origin of Life  

E-print Network

The evolution of life has been a big enigma despite rapid advancements in the fields of biochemistry, astrobiology, and astrophysics in recent years. The answer to this puzzle has been as mind-boggling as the riddle relating to evolution of Universe itself. Despite the fact that panspermia has gained considerable support as a viable explanation for origin of life on the Earth and elsewhere in the Universe, the issue remains far from a tangible solution. This paper examines the various prevailing hypotheses regarding origin of life like abiogenesis, RNA World, Iron-sulphur World, and panspermia; and concludes that delivery of life-bearing organic molecules by the comets in the early epoch of the Earth alone possibly was not responsible for kick-starting the process of evolution of life on our planet.

Life on Titan  

NASA Astrophysics Data System (ADS)

Volcanoes engender life on heavenly bodies; they are pacemakers of life. All planets during their period of formation pass through volcanism hence - all planets and their satellites pass through the life. Tracks of life If we want to find tracks of life - most promising places are places with volcanic activity, current or past. In the case of just-in-time volcanic activity we have 100% probability to find a life. Therefore the most perspective “search for life” are Enceladus, Io and comets, further would be Venus, Jupiter’s satellites, Saturn’s satellites and first of all - Titan. Titan has atmosphere. It might be result of high volcanic activity - from one side, from other side atmosphere is a necessary condition development life from procaryota to eucaryota. Existence of a planet means that all its elements after hydrogen formed just there inside a planet. The forming of the elements leads to the formation of mineral and organic substances and further to the organic life. Development of the life depends upon many factors, e.g. the distance from star/s. The intensity of the processes of the element formation is inversely to the distance from the star. Therefore we may suppose that the intensity of the life in Mercury was very high. Hence we may detect tracks of life in Mercury, particularly near volcanoes. The distance from the star is only one parameter and now Titan looks very active - mainly due to interior reason. Its atmosphere compounds are analogous to comet tail compounds. Their collation may lead to interesting result as progress occurs at one of them. Volcanic activity is as a source of life origin as well a reason for a death of life. It depends upon the thickness of planet crust. In the case of small thickness of a crust the probability is high that volcanoes may destroy a life on a planet - like Noachian deluge. Destroying of the life under volcano influences doesn’t lead to full dead. As result we would have periodic Noachian deluge or nuclear winter. These events are known as extinctions or ice ages. The crust of a planet of the Earth group is formed at the outer edge of the body. The planets after asteroid belt like Jupiter or Saturn probably form their “crusts” in the centre of the body. Due to we may see internal kitchen of element forming in detail. This processes lead to the organic life, which we may detect at the atmospheres of Jupiter, Saturn, Neptune, and Pluto. But their satellites look like earth planet group - with outer crust. Huygens considered that God's wisdom and providence is clearest in the creation of life, and Earth holds no privileged position in the heavens that life must be universal. “Huygens” helps find life on Titan

Auguste Comte's blunder: an account of the first century of stellar spectroscopy and how it took one hundred years to prove that Comte was wrong!  

NASA Astrophysics Data System (ADS)

In 1835 the French philosopher Auguste Comte predicted that we would never know anything about the chemical composition of stars. This paper gives a broad overview of the development of stellar spectroscopy, especially from about 1860. Developments in stellar spectroscopy segregated quite clearly into three main fields of endeavour: spectral classification, radial velocities and spectral analysis. This paper concentrates mainly on spectral analysis, or how stellar spectroscopy one hundred years after Comte showed that quantitative information on the composition of stars was possible. The journey was quite arduous, as it required numerous developments in theoretical physics and in laboratory spectroscopy, which in turn allowed stellar spectral analysis successfully to be undertaken by the mid-twentieth century. The key developments in physics that first had to be understood were in quantum and atomic theory, ionization theory, the concept of the Planck function, local thermodynamic equilibrium, the first stellar model atmospheres, line formation theory, turbulence, collisional broadening of spectral lines and the theory of radiative transfer and of the curve of growth. The close links between stellar spectroscopy and theoretical physics will be emphasized. In addition laboratory physics, to measure line wavelengths and oscillator strengths, was also an essential precursor to quantitative data on the chemical composition of stars. Comte may have been an influential philosopher of science in his time. Perhaps his one small transgression was not to have read the works of Joseph Fraunhofer, which in the early nineteenth century already contained the first small clues that Comte's assertion might be wrong.

The Salmon Louse Lepeophtheirus salmonis (Copepoda: Caligidae) life cycle has only two Chalimus stages.  

PubMed

Each year the salmon louse (Lepeophtheirussalmonis Krøyer, 1838) causes multi-million dollar commercial losses to the salmon farming industry world-wide, and strict lice control regimes have been put in place to reduce the release of salmon louse larvae from aquaculture facilities into the environment. For half a century, the Lepeophtheirus life cycle has been regarded as the only copepod life cycle including 8 post-nauplius instars as confirmed in four different species, including L. salmonis. Here we prove that the accepted life cycle of the salmon louse is wrong. By observations of chalimus larvae molting in incubators and by morphometric cluster analysis, we show that there are only two chalimus instars: chalimus 1 (comprising the former chalimus I and II stages which are not separated by a molt) and chalimus 2 (the former chalimus III and IV stages which are not separated by a molt). Consequently the salmon louse life cycle has only six post-nauplius instars, as in other genera of caligid sea lice and copepods in general. These findings are of fundamental importance in experimental studies as well as for interpretation of salmon louse biology and for control and management of this economically important parasite.

The Errors of Individualistic Public Health Interventions: Denial of Treatment to Obese Persons Comment on "Denial of Treatment to Obese Patients-the Wrong Policy on Personal Responsibility for Health".  

PubMed

I agree entirely with Nir Eyal's perspective that denying treatment to obese patients is morally wrong. However, the reasons for this belief differ in some ways from Eyal's analysis. In this commentary, I will try to explain the similarities and differences in our perspectives. My primary claim is that the denial of treatment to obese patients is wrong principally because (i) it eschews a whole-population approach to the problem of poor nutrition and is therefore likely to be ineffective; (ii) it is likely to expand obesity-related health inequities; and (iii) it is likely to intensify stigma against already-marginalized social groups. I shall consider each in turn, and explore the extent to which Eyal would be likely to agree with my claims. PMID:24596875

Defining life or bringing biology to life.  

PubMed

In the present, post-genomic times, systemic or holistic approaches to living phenomena are compulsory to overcome the limits of traditional strategies, such as the methodological reductionism of molecular biology. In this paper, we propose that theoretical and philosophical efforts to define life also contribute to those integrative approaches, providing a global theoretical framework that may help to deal with or interpret the huge amount of data being collected by current high-throughput technologies, in this so-called 'omics' revolution. We claim that two fundamental notions can capture the core of the living, (basic) autonomy and open-ended evolution, and that only the complementary combination of these two theoretical constructs offers an adequate solution to the problem of defining the nature of life in specific enough-but also encompassing enough-terms. This tentative solution should also illuminate, in its most elementary version, the leading steps towards living beings on Earth. PMID:20182798

This paper describes the development plan and design concept of the Regenerative Life Support Evaluation (RLSE) planned for flight testing in the European Space Agency Spacelab. The development plan encompasses the ongoing advanced life support subsystem and a systems integration effort to evolve concurrently subsystem concepts that perform their function and can be integrated with other subsystems in a flight demonstration of a regenerative life support system. The design concept for RLSE comprises water-electrolysis O2 generation, electrochemically depolarized CO2 removal, and Sabatier CO2 reduction for atmosphere regeneration, urine vapor-compression distillation, and wash-water hyperfiltration for waste-water recovery. The flight demonstration by RLSE is an important step in qualifying the regenerative concepts for life support in space stations.

From the anthropic perspective it is therefore important to understand whether complex life is possible on moduli space - i.e., in low-energy effective theories with (1) exact supersymmetry and (2) some massless multiplets (moduli). Unless life is essentially impossible on moduli space as a consequence of these characteristics, anthropic reasoning in string theory suggests that the overwhelming majority of sentient beings would observe 1-2. We investigate whether 1 and 2 are by themselves automatically inimical to life and conclude, tentatively, that they are not. In particular, we describe moduli scenarios in which complex life seems possible.

Life Has A History  

NSDL National Science Digital Library

This website provides students with an introduction to the history of life and how it resulted in today's biodiversity. There are three tiers of difficulty available for different grade levels. During this tour students learn about geologic time, fossils, ancestral relationships, cladograms, variation, natural selection, and extinction. Students learn that life has been around for a very long time and is the result of evolution. They learn that fossils provide evidence of past life, that much of past life is now extinct, and that evolutionary relationships of organisms can be illustrated as cladograms. Using the Galapagos finches as an example, students learn the importance of variation and natural selection in evolution, as well as the biodiversity we see on Earth today. The teacher's section provides all necessary information for implementing this module, including lesson plans, handouts, and assessment ideas.

Life on Mars Revisited  

NSDL National Science Digital Library

When NASA researchers from the Johnson Space Center and Stanford University announced they had found combined evidence in 1996 "that strongly suggests primitive life may have existed on Mars more than 3.6 billion years ago," scientists buzzed with excitement at the possibility of life on Mars. Two weeks ago, the discovery of rock-eating microbes one mile beneath the ocean floor (published in the August 14, 1998 issue of Science) seemed to make that possibility more likely. But last week, new evidence based on geochemical models was discovered that indicates that, while basic geological conditions on Mars may meet life's minimal requirements, the biological potential of the red planet seems unlikely. The nine resources listed provide background information, specifics, and commentary on the hunt for Life on Mars.

Life sciences recruitment objectives  

NASA Technical Reports Server (NTRS)

The goals of the Life Sciences Division of the Office of Space Sciences and Application are to ensure the health, well being and productivity of humans in space and to acquire fundamental scientific knowledge in space life sciences. With these goals in mind Space Station Freedom represents substantial opportunities and significant challenges to the Life Sciences Division. For the first time it will be possible to replicate experimental data from a variety of simultaneously exposed species with appropriate controls and real-time analytical capabilities over extended periods of time. At the same time, a system for monitoring and ameliorating the physiological adaptations that occur in humans subjected to extended space flight must be evolved to provide the continuing operational support to the SSF crew. To meet its goals, and take advantage of the opportunities and overcome the challenges presented by Space Station Freedom, the Life Sciences Division is developing a suite of discipline-focused sequence. The research phase of the Life Sciences Space Station Freedom Program will commence with the utilization flights following the deployment of the U.S. laboratory module and achievement of Man Tended Capability. Investigators that want the Life Sciences Division to sponsor their experiment on SSF can do so in one of three ways: submitting a proposal in response to a NASA Research Announcement (NRA), submitting a proposal in response to an Announcement of Opportunity (AO), or submitting an unsolicited proposal. The scientific merit of all proposals will be evaluated by peer review panels. Proposals will also be evaluated based on relevance to NASA's missions and on the results of an Engineering and Cost Analyses. The Life Sciences Division expects that the majority of its funding opportunities will be announced through NRA's. It is anticipated that the first NRA will be released approximately three years before first element launch (currently scheduled for late 1995). Subsequent NRA's will be released on a rotating two year cycle.

Intelligent life in cosmology  

NASA Astrophysics Data System (ADS)

I shall present three arguments for the proposition that intelligent life is very rare in the universe. First, I shall summarize the consensus opinion of the founders of the modern synthesis (Simpson, Dobzhanski and Mayr) that the evolution of intelligent life is exceedingly improbable. Secondly, I shall develop the Fermi paradox: if they existed, they would be here. Thirdly, I shall show that if intelligent life were too common, it would use up all available resources and die out. But I shall show that the quantum mechanical principle of unitarity (actually a form of teleology!) requires intelligent life to survive to the end of time. Finally, I shall argue that, if the universe is indeed accelerating, then survival to the end of time requires that intelligent life, though rare, to have evolved several times in the visible universe. I shall argue that the acceleration is a consequence of the excess of matter over antimatter in the universe. I shall suggest experiments to test these claims.

What's wrong with risk matrices?  

PubMed

Risk matrices-tables mapping "frequency" and "severity" ratings to corresponding risk priority levels-are popular in applications as diverse as terrorism risk analysis, highway construction project management, office building risk analysis, climate change risk management, and enterprise risk management (ERM). National and international standards (e.g., Military Standard 882C and AS/NZS 4360:1999) have stimulated adoption of risk matrices by many organizations and risk consultants. However, little research rigorously validates their performance in actually improving risk management decisions. This article examines some mathematical properties of risk matrices and shows that they have the following limitations. (a) Poor Resolution. Typical risk matrices can correctly and unambiguously compare only a small fraction (e.g., less than 10%) of randomly selected pairs of hazards. They can assign identical ratings to quantitatively very different risks ("range compression"). (b) Errors. Risk matrices can mistakenly assign higher qualitative ratings to quantitatively smaller risks. For risks with negatively correlated frequencies and severities, they can be "worse than useless," leading to worse-than-random decisions. (c) Suboptimal Resource Allocation. Effective allocation of resources to risk-reducing countermeasures cannot be based on the categories provided by risk matrices. (d) Ambiguous Inputs and Outputs. Categorizations of severity cannot be made objectively for uncertain consequences. Inputs to risk matrices (e.g., frequency and severity categorizations) and resulting outputs (i.e., risk ratings) require subjective interpretation, and different users may obtain opposite ratings of the same quantitative risks. These limitations suggest that risk matrices should be used with caution, and only with careful explanations of embedded judgments. PMID:18419665

Stress and life history.  

PubMed

In his book on behavioural endocrinology, Randy Nelson describes 'stress' as a 'notoriously ethereal concept'. Yet, despite this lack of clarity, studies of the consequences of stress across different time scales, life history stages, taxa and levels of biological enquiry form a large part of modern biology and biomedicine. Organisms need to recognise and respond to environmental challenges. Being able to do so appropriately, and with minimal costs, is an important physiological attribute, with great adaptive value. The costs and benefits of different mechanisms that enable organisms to cope with unpredictable environmental changes can be manifest to different degrees at different life stages. Accordingly, the level of stress experienced in the environment can act as a strong selective pressure that drives the evolution of life histories. PMID:24845673

In this “clicker case,” students learn about meiosis through the real-life story of a couple who used pre-implantation genetic screening to select an embryo that was a genetic match for an older sibling with leukemia, and thus able to provide a source of bone marrow cells. The case caused a stir in the medical ethics community.  Before this, parents had only used pre-implantation genetic screening to select for a baby that would be free from a genetic disorder. Instead, this child was conceived as a treatment for his older sister.  The case was developed for use in an introductory biology course.  It consists of a PowerPoint presentation (~1.5MB) shown in class that is punctuated by multiple-choice questions the students respond to using clickers.

The role of bundle sheath extensions and life form in stomatal responses to leaf water status.  

PubMed

Bundle sheath extensions (BSEs) are key features of leaf structure with currently little-understood functions. To test the hypothesis that BSEs reduce the hydraulic resistance from the bundle sheath to the epidermis (r(be)) and thereby accelerate hydropassive stomatal movements, we compared stomatal responses with reduced humidity and leaf excision among 20 species with heterobaric or homobaric leaves and herbaceous or woody life forms. We hypothesized that low r(be) due to the presence of BSEs would increase the rate of stomatal opening (V) during transient wrong-way responses, but more so during wrong-way responses to excision (V(e)) than humidity (V(h)), thus increasing the ratio of V(e) to V(h). We predicted the same trends for herbaceous relative to woody species given greater hydraulic resistance in woody species. We found that V(e), V(h), and their ratio were 2.3 to 4.4 times greater in heterobaric than homobaric leaves and 2.0 to 3.1 times greater in herbaceous than woody species. To assess possible causes for these differences, we simulated these experiments in a dynamic compartment/resistance model, which predicted larger V(e) and V(e)/V(h) in leaves with smaller r(be). These results support the hypothesis that BSEs reduce r(be). Comparison of our data and simulations suggested that r(be) is approximately 4 to 16 times larger in homobaric than heterobaric leaves. Our study provides new evidence that variations in the distribution of hydraulic resistance within the leaf and plant are central to understanding dynamic stomatal responses to water status and their ecological correlates and that BSEs play several key roles in the functional ecology of heterobaric leaves.

Starship Life Support  

NASA Technical Reports Server (NTRS)

The design and mass cost of a starship and its life support system are investigated. The mission plan for a multi generational interstellar voyage to colonize a new planet is used to describe the starship design, including the crew habitat, accommodations, and life support. Only current technology is assumed. Highly reliable life support systems can be provided with reasonably small additional mass, suggesting that they can support long duration missions. Bioregenerative life support, growing crop plants that provide food, water, and oxygen, has been thought to need less mass than providing stored food for long duration missions. The large initial mass of hydroponics systems is paid for over time by saving the mass of stored food. However, the yearly logistics mass required to support a bioregenerative system exceeds the mass of food solids it produces, so that supplying stored dehydrated food always requires less mass than bioregenerative food production. A mixed system that grows about half the food and supplies the other half dehydrated has advantages that allow it to breakeven with stored dehydrated food in about 66 years. However, moderate increases in the hydroponics system mass to achieve high reliability, such as adding spares that double the system mass and replacing the initial system every 100 years, increase the mass cost of bioregenerative life support. In this case, the high reliability half food growing, half food supplying system does not breakeven for 389 years. An even higher reliability half and half system, with three times original system mass and replacing the system every 50 years, never breaks even. Growing food for starship life support requires more mass than providing dehydrated food, even for multigeneration voyages of hundreds of years. The benefits of growing some food may justify the added mass cost. Much more efficient recycling food production is wanted but may not be possible. A single multigenerational interstellar voyage to colonize a new planet would have cost similar to that of the Apollo program. Cost is reduced if a small crew travels slowly and lands with minimal equipment. We can go to the stars!

Two contributions from Dr Ivan Illich follow. The first, in which he sets out his primary thesis of the medicalization of life, is a section from Dr Illich's book `Medical Nemesis'. (It is reprinted with the permission of the author and his publishers, Messrs Calder and Boyars.) The second is a transcript of the paper which Dr Illich read at the conference organized by the London Medical Group on iatrogenic disease. Both are ultimately addressed to the recipients of medical care, the general public, although the second paper is specifically addressed to young doctors and medical students. For Dr Illich the world is suffering from too much medical interference, and a medical edifice has been built which is one of the threats to the real life of human beings - a threat which so far has been disguised as care.

Bioenergetics and Life's Origins  

PubMed Central

Bioenergetics is central to our understanding of living systems, yet has attracted relatively little attention in origins of life research. This article focuses on energy resources available to drive primitive metabolism and the synthesis of polymers that could be incorporated into molecular systems having properties associated with the living state. The compartmented systems are referred to as protocells, each different from all the rest and representing a kind of natural experiment. The origin of life was marked when a rare few protocells happened to have the ability to capture energy from the environment to initiate catalyzed heterotrophic growth directed by heritable genetic information in the polymers. This article examines potential sources of energy available to protocells, and mechanisms by which the energy could be used to drive polymer synthesis. PMID:20182625

Ethical issues in end-of-life geriatric care: the approach of three monotheistic religions-Judaism, Catholicism, and Islam.  

PubMed

Ethical dilemmas pervade modern geriatric medicine. What is considered right or wrong will differ depending on, among other things, the patient's religion. The three Abrahamic monotheistic religions, Judaism, Christianity (its Catholic variant), and Islam all have carefully considered positions on medical ethics. Although much is held in common, there are significant differences. The authors present three clinical cases, each of which presents ethical dilemmas typical of geriatric care, especially at the end of life. On the basis of these scenarios, the normative ethical position of each religion is compared and contrasted. It is hoped that this approach will offer the geriatrician a useful approach to treating patients in an increasingly multicultural society. PMID:12890081

Some promising newer approaches for detecting microorganisms are discussed, giving particular attention to the integration of different methods into a single instrument. Life detection methods may be divided into biological, chemical, and cytological methods. Biological methods are based on the biological properties of assimilation, metabolism, and growth. Devices for the detection of organic materials are considered, taking into account an instrument which volatilizes, separates, and analyzes a sample sequentially. Other instrumental systems described make use of a microscope and the cytochemical staining principle.

The paper concludes by suggesting that talk about responsibilities may be more fruitful than talk about rights. PMID:7277408

Harnessing our very life.  

PubMed

The Aristotelian ideas of nature (physis) and technology (techné) are taken as a starting point for understanding what it would mean for technology to be truly living. Heidegger's critique of the conflation of scientific and technological thinking in the current era is accepted as demonstrating that humanity does not have a deep enough appreciation of the nature of life to harness its essence safely. Could the vision of harnessing life be realized, which we strongly doubt, living technology would give selected humans transforming powers that could be expected to exacerbate, rather than solve, current global problems. The source of human purposefulness, and hence of both technology and ethics, is identified in nature's emergent capability to instantiate informational representations in material forms. Ethics that are properly grounded in an appreciation of intrinsic value, especially that of life, demand that proposals to give humanity the capabilities of living technology address the social, political, economic, and environmental problems inherent in its development and potential deployment. Before any development is embarked on, steps must be taken to avoid living technology, whatever the term eventually designates, becoming available for destructive or antisocial purposes such as those that might devastate humanity or irrevocably damage the natural world.

Sleep and Sex: What Can Go Wrong? A Review of the Literature on Sleep Related Disorders and Abnormal Sexual Behaviors and Experiences  

PubMed Central

Study Objectives: To formulate the first classification of sleep related disorders and abnormal sexual behaviors and experiences. Design: A computerized literature search was conducted, and other sources, such as textbooks, were searched. Results: Many categories of sleep related disorders were represented in the classification: parasomnias (confusional arousals/sleepwalking, with or without obstructive sleep apnea; REM sleep behavior disorder); sleep related seizures; Kleine-Levin syndrome (KLS); severe chronic insomnia; restless legs syndrome; narcolepsy; sleep exacerbation of persistent sexual arousal syndrome; sleep related painful erections; sleep related dissociative disorders; nocturnal psychotic disorders; miscellaneous states. Kleine-Levin syndrome (78 cases) and parasomnias (31 cases) were most frequently reported. Parasomnias and sleep related seizures had overlapping and divergent clinical features. Thirty-one cases of parasomnias (25 males; mean age, 32 years) and 7 cases of sleep related seizures (4 males; mean age, 38 years) were identified. A full range of sleep related sexual behaviors with self and/or bed partners or others were reported, including masturbation, sexual vocalizations, fondling, sexual intercourse with climax, sexual assault/rape, ictal sexual hyperarousal, ictal orgasm, and ictal automatism. Adverse physical and/or psychosocial effects from the sleepsex were present in all parasomnia and sleep related seizure cases, but pleasurable effects were reported by 5 bed partners and by 3 patients with sleep related seizures. Forensic consequences were common, occurring in 35.5% (11/31) of parasomnia cases, with most (9/11) involving minors. All parasomnias cases reported amnesia for the sleepsex, in contrast to 28.6% (2/7) of sleep related seizure cases. Polysomnography (without penile tumescence monitoring), performed in 26 of 31 parasomnia cases, documented sexual moaning from slow wave sleep in 3 cases and sexual intercourse during stage 1 sleep/wakefulness in one case (with sex provoked by the bed partner). Confusional arousals (CAs) were diagnosed as the cause of “sleepsex” (“sexsomnia”) in 26 cases (with obstructive sleep apnea [OSA] comorbidity in 4 cases), and sleepwalking in 2 cases, totaling 90.3% (28/31) of cases being NREM sleep parasomnias. REM behavior disorder was the presumed cause in the other 3 cases. Bedtime clonazepam therapy was effective in 90% (9/10) of treated parasomnia cases; nasal continuous positive airway pressure therapy was effective in controlling comorbid OSA and CAs in both treated cases. All five treated patients with sleep related sexual seizures responded to anticonvulsant therapy.

Effect of Individual Component Life Distribution on Engine Life Prediction  

NASA Technical Reports Server (NTRS)

The effect of individual engine component life distributions on engine life prediction was determined. A Weibull-based life and reliability analysis of the NASA Energy Efficient Engine was conducted. The engine s life at a 95 and 99.9 percent probability of survival was determined based upon the engine manufacturer s original life calculations and assumed values of each of the component s cumulative life distributions as represented by a Weibull slope. The lives of the high-pressure turbine (HPT) disks and blades were also evaluated individually and as a system in a similar manner. Knowing the statistical cumulative distribution of each engine component with reasonable engineering certainty is a condition precedent to predicting the life and reliability of an entire engine. The life of a system at a given reliability will be less than the lowest-lived component in the system at the same reliability (probability of survival). Where Weibull slopes of all the engine components are equal, the Weibull slope had a minimal effect on engine L(sub 0.1) life prediction. However, at a probability of survival of 95 percent (L(sub 5) life), life decreased with increasing Weibull slope.

Four life-threatening dermatoses—Stevens-Johnson syndrome, toxic epidermal necrolysis, Kaposi's varicelliform eruption and purpura fulminans—are unique in their abrupt onset and rapid progress to death, but prompt diagnosis and proper therapy can often cure the condition or prevent undesirable sequelae. Since two of the four conditions can follow the use of a variety of drugs and all may be secondary to an infectious agent, any physician may encounter them in practice and should be aware of their seriousness.

Exploring for Martian Life  

NASA Technical Reports Server (NTRS)

During the next decade, robotic field science will play an essential role in advancing our understanding of Martian history. Specifically, capable rovers are needed to survey a broad range of Martian rock types for in situ chemistry and mineralogy as a basis for interpreting globally-distributed data obtained from orbit. The relationship between orbital and landed science will be fundamental in selecting a landing site for future missions aimed at probing the ancient rock record for evidence of: (1) past life or prebiotic chemistry; (2) the climate and volatile history of Mars; and (3) candidate materials for in situ resource utilization.

Life Before Oxygen  

NSDL National Science Digital Library

About three billion years ago, single-celled underwater bacteria similar to modern cyanobacteria consumed carbon dioxide as they photosynthesized, releasing oxygen in the process. In this way, an atmosphere full of volcanic carbon dioxide gradually changed into an oxygen-rich atmosphere in which animal life could survive, except for some primitive organisms, who retreated to oxygen-poor environments. This video segment shows researchers as they search for these organisms, which are now considered tiny time capsules from the time before there was oxygen on Earth. The segment is one minute thirty-nine seconds in length. A background essay and list of discussion questions are also provided.

Quality of life philosophy I. Quality of life, happiness, and meaning in life.  

PubMed

In the Danish Quality of Life Survey, we asked 10,000 people about their quality of life with the validated SEQOL questionnaire with more than 300 questions on their quality of life. How did they feel? How content were they with their lives? How happy were they? Did they feel their needs were fulfilled? And many more questions. We asked the questions we believed to be important for their quality of life (QOL). The results were quite surprising and forced us to recontemplate the following philosophical questions: What is quality of life, happiness, and meaning in life? What is a human being? Do we need a new biology? Is the brain the seat of consciousness? How do we seize the meaning of life and by doing so, will we become well again? What are the key concepts of quality of life? The meaning of life is connectedness and development. It is about realizing every opportunity and potential in one"s existence. The opportunities must be found and acknowledged. What do you find when you find yourself deep down? You find your real self and your purpose in life. You realize that you are already a part of a larger totality. Antonovsky called it "coherence". Maslow called it "transcendence". Frankl called it "meaning of life". We call it simply "being". To test if these philosophical questions are actually relevant for medicine, we looked at the consequences for patients being taught the quality of life philosophy. Quite surprisingly we learned from our pilot studies with "quality of life as medicine" that just by assimilating the basic concepts of the quality of life philosophy presented in this series of papers, patients felt better and saw their lives as more meaningful. The improvement of the patient"s personal philosophy of life seems to be the essence of holistic medicine, helping the patient to assume more responsibility for his or her own existence.

Creativity in later life.  

PubMed

The ageing population presents significant challenges for the provision of social and health services. Strategies are needed to enable older people to cope within a society ill prepared for the impacts of these demographic changes. The ability to be creative may be one such strategy. This review outlines the relevant literature and examines current public health policy related to creativity in old age with the aim of highlighting some important issues. As well as looking at the benefits and negative aspects of creative activity in later life they are considered in the context of the theory of "successful ageing". Creative activity plays an important role in the lives of older people promoting social interaction, providing cognitive stimulation and giving a sense of self-worth. Furthermore, it is shown to be useful as a tool in the multi-disciplinary treatment of health problems common in later life such as depression and dementia. There are a number of initiatives to encourage older people to participate in creative activities such as arts-based projects which may range from visual arts to dance to music to intergenerational initiatives. However, participation shows geographical variation and often the responsibility of provision falls to voluntary organisations. Overall, the literature presented suggests that creative activity could be a useful tool for individuals and society. However, further research is needed to establish the key factors which contribute to patterns of improved health and well-being, as well as to explore ways to improve access to services.

Life from the core  

NASA Astrophysics Data System (ADS)

Life on Earth is the result of the chaotic combination of several independent chemical and physical parameters. One of them is the shield from ionizing radiation exerted by the atmosphere and the Earth's magnetic field. We hypothesise that the first few billion years of the Earth's history, dominated by bacteria, were characterized by stronger ionizing radiation. Bacteria can survive under such conditions better than any other organism. During the Archean and early Proterozoic the shield could have been weaker, allowing the development of only a limited number of species, more resistant to the external radiation. The Cambrian explosion of life could have been enhanced by the gradual growth of the solid inner core, which was not existent possibly before 1 Ga. The cooling of the Earth generated the solidification of the iron alloy in the center of the planet. As an hypothesis, before the crystallization of the core, the turbulence in the liquid core could have resulted in a lower or different magnetic field from the one we know today, being absent the relative rotation between inner and external core.

Venus: Water and Life  

NASA Astrophysics Data System (ADS)

Amphiboles that contain the hydroxide ion form only in the presence of water and this fact has become the way for scientists to prove that Venus was once a water world. Though, tremolite is considered the main mineral to look for, it requires life that is analogous to the ancient life here on Earth for it to form. Dolomite is the main ingredient for the formation of this low grade metamorphic mineral and without it would be very difficult for tremolite to form, unless there is another process that is unknown to science. Venus is known to have extensive volcanic features (over 1600 confirmed shield volcanoes dot its surface) and with little erosion taking place; a mineral that is associated with volcanism and forms only in the presence of water should be regarded as the main goal. Hornblende can form via volcanism or a metamorphic process but requires water for initial formation. The European Space Agency is currently trying to determine whether or not the continents on Venus' surface are made of granite, as they argue granite requires water for formation. Either way, computer models suggest that any oceans that formed on the surface would have lasted at best 2 billion years, as the surface is estimated to be only 800 million years old, any hornblende that would have formed is more than likely going to be deep underground. To find this mineral, as well as others, it would require a mission that has the ability to drill into the surface, as the easiest place to do this would be on the mountain peaks in the Northern Hemisphere on the Ishtar Terra continent. Through the process of uplift, any remaining hornblende may have been exposed or very near exposed to the surface. Do to the amount of fluorine in the atmosphere and the interaction between this and the lithosphere, the hydroxyl ions may have been replaced with fluorine turning the hornblende into the more stable fluoro-hornblende. To further add to the mystery of Venus is the unusual atmospheric composition. The presence of both sulfur dioxide and hydrogen sulfide demand further research as these gases are not being replenished by any geologic activity. Both of these compounds are found is sufficient quantity in the cloud decks, but are almost nonexistent at the surface, further supporting the idea of a chemical reaction/process in the atmosphere. There are particles that have been detected in the atmosphere that seem to be absorbing UV radiation is also located at these same altitudes. Finding tremolite on Venus would only further excite the possibility that we are not alone in the universe. Could life on Venus be related to life here on Earth? Where in the Solar System did life originate? These are questions that would need serious thought if such an event took place. Finding hornblende on Venus would give further support to several theories, but finding tremolite would change everything.

NASA Technical Reports Server (NTRS)

The concept of Life Extending Control is defined. Life is defined in terms of mechanical fatigue life. A brief description is given of the current approach to life prediction using a local, cyclic, stress-strain approach for a critical system component. An alternative approach to life prediction based on a continuous functional relationship to component performance is proposed.Base on cyclic life prediction an approach to Life Extending Control, called the Life Management Approach is proposed. A second approach, also based on cyclic life prediction, called the Implicit Approach, is presented. Assuming the existence of the alternative functional life prediction approach, two additional concepts for Life Extending Control are presented.

Defining Life: Synthesis and Conclusions  

NASA Astrophysics Data System (ADS)

The first part of the paper offers philosophical landmarks on the general issue of defining life. §1 defends that the recognition of “life” has always been and remains primarily an intuitive process, for the scientist as for the layperson. However we should not expect, then, to be able to draw a definition from this original experience, because our cognitive apparatus has not been primarily designed for this. §2 is about definitions in general. Two kinds of definition should be carefully distinguished: lexical definitions (based upon current uses of a word), and stipulative or legislative definitions, which deliberately assign a meaning to a word, for the purpose of clarifying scientific or philosophical arguments. The present volume provides examples of these two kinds of definitions. §3 examines three traditional philosophical definitions of life, all of which have been elaborated prior to the emergence of biology as a specific scientific discipline: life as animation (Aristotle), life as mechanism, and life as organization (Kant). All three concepts constitute a common heritage that structures in depth a good deal of our cultural intuitions and vocabulary any time we try to think about “life”. The present volume offers examples of these three concepts in contemporary scientific discourse. The second part of the paper proposes a synthesis of the major debates developed in this volume. Three major questions have been discussed. A first issue (§4) is whether we should define life or not, and why. Most authors are skeptical about the possibility of defining life in a strong way, although all admit that criteria are useful in contexts such as exobiology, artificial life and the origins of life. §5 examines the possible kinds of definitions of life presented in the volume. Those authors who have explicitly defended that a definition of life is needed, can be classified into two categories. The first category (or standard view) refers to two conditions: individual self-maintenance and the open-ended evolution of a collection of similar entities. The other category refuse to include reproduction and evolution, and take a sort of psychic view of the living. §6 examines the relationship between the question of the definition of life and that of the origins of life. There is a close parallel between the general conceptions of the origins of life and the definitions of life.

Kelly says that it is a completely different type of hydrothermal system not requiring volcanic heat, and that it has implications for examining early Earth questions and hydrothermal systems on other planets. The find opens the possibility that a much larger portion of the seafloor may host hydrothermal vents (and microbial life) than was previously thought. The site contains descriptions of some of the unique topographical features of the field, and the thermal chemistry that drives the formation of this type of feature.

Their Circular Life  

NSDL National Science Digital Library

This rather provocative website (which requires Macromedia Flash Player) explores various urban environments around Italy and draws visitors into the life of a "typical" day in the different lives of these seemingly ordinary places. The website was created by Lorenzo Fonda and David Terenzi and features original music and a rather welcoming user interface for exploring the different environments. The interface for each of the five urban places allows users to drag a small triangle around a circle, and essentially move through a series of images (and related sounds recorded on site) that take place during a single day. The places featured on the site include the train station in Modena, the Campo San Barnaba in Venezia, and three additional locales. Overall, this site offers a fascinating way of looking at and experiencing different urban environments and a potential template for future online projects.

Fossil life on Mars  

NASA Technical Reports Server (NTRS)

Three major problems beset paleontologists searching for morphological evidence of life on early Earth: selecting a prospective site; finding biogenic structures; and distinguishing biogenic from abiogenic structures. The same problems arise on Mars. Terrestrial experience suggests that, with the techniques that can be employed remotely, ancient springs, including hot springs, are more prospective than lake deposits. If, on the other hand, the search is for chemical evidence, the strategy can be very different, and lake deposits are attractive targets. Lakes and springs frequenly occur in close proximity, and therefore a strategy that combines the two would seem to maximize the chance of success. The strategy for a search for stromatolite on Mars is discussed.

Evolution of Life  

NSDL National Science Digital Library

A number of groups are celebrating the 150th anniversary of the publication of "On the Origin of Species by Means of Natural Selection" by Charles Darwin. This educational site, created with funds provided by VolkswagenStiftung, celebrates this anniversary by offering videos, animations, and documents for teachers that explore the origins of life and evolution. The materials here are divided into three sections: "Observe", "Explore", and "Teach". In the "Observe" area, visitors can watch several short films, including the "O as Origin" movie, which follows a water molecule named "Piccolina" as she moves forward through time and becomes more and more complex along the way. There's also another film here that follows Darwin as he works on some of his discoveries and theories. Visitors can also elect to listen to these videos in French, English, and German, and they will also want to sign up to receive email updates when new material is added to the site.

Game of Life Music  

NASA Astrophysics Data System (ADS)

At the time when the first author was post-graduate student, in the evenings he used to entertain himself with the equipment in the electronic music studio at the University of York until dawn. It must have been around three o'clock in the morning of a rather cold winter night in the late 1980s, when he connected his Atari 1040ST computer to a synthesizer to test the first prototype of a system, which he was developing for his thesis. The system, named CAMUS (short for Cellular Automata Music), implemented a method that he invented to render music from the behaviour of the Game of Life (GoL) cellular automata (CA).

Utah's Cambrian Life  

NSDL National Science Digital Library

What was going on in Utah 500 million years ago? Quite a bit, and this website provides an excellent overview of the diverse Cambrian life that flourished in an ancient sea that covered what is now the Beehive State. Interestingly enough, the website was created by the division of invertebrate paleontology at the University of Kansas Natural History Museum, and it includes images of a wide array of fossilized materials from this period of geological history. On the left-hand side of the page, visitors will find four primary sections, including "Localities and Geology" and "Online Fossil Exhibits and Collections". The "Localities and Geology" area is a good place to start as it gives an overview (complete with aerial photographs and maps) of the Cambrian period in Utah. The "Online Fossil Exhibits and Collections" area features fossil representative images from groups like mollusks, algae, jellyfish, and lobopods.

Life in the Cambrian  

NSDL National Science Digital Library

This site describes the Cambrian fossil record, which indicates a distinct development from simple organisms to organisms comparable in morphology and organization to present-day animals. The development is documented by faunal assemblages represented by the Ediacara fauna, the first complex trace fossils, the earliest shelly faunas, and the onset of the typical Cambrian macrofaunas. This rapid evolution took place in an interval of less than 25 million years and the evolution from the first hard-part animals to the presence of most of the present-day phyla was restricted to an interval of probably less than 10 million years. Multicellular life evolved at an incredible speed and for this reason this part of organismal evolution is termed the Cambrian Explosion, or Evolutions Big Bang. The site describes each group of fossils and also the locations where the faunal assemblages were found.

The Origin of Life  

NSDL National Science Digital Library

In modern organisms, there is a division of labor between two kinds of molecule: DNA, which stores and transmits genetic information, and proteins, which do all the work. They are connected by the genetic code, whereby DNA specifies what kinds of proteins can be made. This process of translation is well understood, but it is far too complicated to have arisen by chance in the primitive oceans. This video lecture explores how this apparent paradox can be resolved. The video explains: the importance of heredity to the definition of life; how nucleotides pair and transfer information; how tRNA is used to transfer a message to enzymes; and how evolution consists of several major changes in the way information is stored, transmitted, and used. The video is 1 hour in length.

Airframe life prediction  

NASA Technical Reports Server (NTRS)

The required research to develop improved life prediction methods for metallic and composite structures under severe thermomechanical loading must include the development of a verified thermoinelastic fracture criterion. There has been much work in this area with many fracture criteria being proposed. Due to the lack of adequate experimental verification none of them are widely accepted. Research must also be performed to develop and implement improved thermoinelasticity theories that properly model large temperature excursions and high temperature gradient. This research is required to provide confidence in the simpler theories currently used for thermoinelastic analysis. Finally, experimental data is needed to define the behavior of and damage accumulation process in thermoinelastic materials. Special emphasis must be placed on understanding failure mode transitions under thermomechanical loading conditions.

Water and Life on Mars  

NASA Technical Reports Server (NTRS)

Mars appears to be cold dry and dead world. However there is good evidence that early in its history it had liquid water, more active volcanism, and a thicker atmosphere. Mars had this earth-like environment over three and a half billion years ago, during the same time that life appeared on Earth. The main question in the exploration of Mars then is the search for a independent origin of life on that planet. Ecosystems in cold, dry locations on Earth - such as the Antarctic - provide examples of how life on Mars might have survived and where to look for fossils. Although the Viking results may indicate that Mars has no life today, there is direct geomorphological evidence that, in the past, Mars had large amounts of liquid water on its surface - possibly due to a thicker atmosphere. From a biological perspective the existence of liquid water, by itself motivates the question of the origin of life on Mars. One of the martian meteorites dates back to this early period and may contain evidence consistent with life. From studies of the Earth's earliest biosphere we know that by 3.5 Gyr. ago, life had originated on Earth and reached a fair degree of biological sophistication. Surface activity and erosion on Earth make it difficult to trace the history of life before the 3.5 Gyr timeframe. Ecosystems in cold, dry locations on Earth - such as the Antarctic - provide examples of how life on Mars might have survived and where to look for fossils.

Extraterrestrial Life: Life on Mars - Then and Now  

NASA Technical Reports Server (NTRS)

The recent claim to have identified possible signs of ancient life on Mars has been widely publicized and discussed. The authors conceded that none of the half-dozen pieces of evidence adduced in their paper individually provided strong support for extraterrestrial life, though they argued that the pieces added up to a case worth considering. Most - perhaps all - of the observed phenomena have counterparts in the inorganic world, so even the combination does not make a compelling case that there was ever life on Mars. Nevertheless, the importance of the problem has justified bringing the results to general attention. The paper has focussed interest on the origin and possible ubiquity of life, and on how we can design techniques capable of giving a more definitive answer to the question of whether there is, or has ever been, life elsewhere in the Universe.

Halophilic life on Mars ?  

NASA Astrophysics Data System (ADS)

Background: The search for extraterrestrial life has been declared as a goal for the 21th century by several space agencies. Potential candidates are microorganisms on or in the surface of moons and planets, such as Mars. Extremely halophilic archaea (haloarchaea) are of astrobiological interest since viable strains have been isolated from million years old salt deposits (1) and halite has been found in Martian meteorites and in surface pools. Therefore, haloarchaeal responses to simulated and real space conditions were explored. Immuno assays for a potential Life Marker Chip experiment were developed with antisera against the universal enzyme ATP synthase. Methods: The focus of these studies was on the application of fluorescent probes since they provide strong signals, and detection devices are suitable for miniaturization. Viability of haloarchaeal strains (Halococcus dombrowskii and Halobacterium salinarum NRC-1) was probed with the LIVE/DEAD BacLight™ kit and the BacLight™ Bacterial Membrane Potential kit. Cyclobutane pyrimidine dimers (CPD) in the DNA, following exposure to simulated and real space conditions (UV irradiation from 200 - 400 nm; 18 months exposure on the International Space Station [ISS] within the ADAPT experiment by Dr. P. Rettberg), were detected with fluorescent Alexa-Fluor-488-coupled antibodies. Immuno assays with antisera against the A-ATPase subunits from Halorubrum saccharovorum were carried out with the highly sensitive Immun-Star ™ WesternC ™ chemiluminescent kit (Bio-Rad). Results: Using the LIVE/DEAD BacLight™ kit, the D37 (dose of 37% survival) for Hcc. dombrowskii and Hbt. salinarum NRC-1, following exposure to UV (200-400 nm) was about 400 kJ/m2, when cells were embedded in halite and about 1 kJ/m2, when cells were in liquid cultures. Fluorescent staining indicated a slightly higher cellular activity than that which was derived from the determination of colony forming units. Assessment of viability with the BacLight™ Bacterial Membrane Potential kit gave strong signals with Hcc. dombrowskii and the control microorganism E. coli; as expected, the uncoupler CCCP diminished the membrane potential. Reaction times were generally longer with Hcc. dombrowskii than with E. coli. Hcc. dombrowskii from the ISS experiment showed > 80% viable cells when judged with the LIVE/DEAD kit. CPD formation was detectable in about 3-5 % of the total cells. It is not yet known if growing cells of Hcc. dombrowskii were recovered from the ISS. ATPase subunits were detected in crude membrane preparations, in whole haloarchaeal and bacterial cells, and even in spores (from Geobacillus stearothermophilus), suggesting the usefulness of the ATP synthase as a molecular target for life detection. Conclusions: Fluorescent dyes provide strong signals, which are suitable for remote detection and are compatible with high ionic strength. The advantages of staining with fluorescent dyes are rapid results on membrane intactness, membrane potential, and the presence of certain biomolecules. But more data are needed for a better correlation to cellular viability.

Self Righting Life Raft  

NASA Technical Reports Server (NTRS)

The Givens Buoy Raft was designed and manufactured for inventor Jim Givens of Givens Marine Survival Co. Inc., by RPR Industries, Inc. The Raft consists of a canopied topside and an underwater hemispheric ballast chamber. It has a heavy ballast stabilization system, adopted from NASA technology, which negates the capsizing problem. A "flapper valve" admits large amounts of water to the hemisphere chamber providing ballast to keep the center of gravity constant; stabilization system compensates for changes in wave angle and weight shifting of raft occupants. Mr. Givens has an exclusive patent license for use of the NASA technology. Produced in various sizes, capacities range from six to 20 persons. Raft is housed in a canister, available in several configurations. A pull on a line triggers the automatic inflation process, which takes 12 seconds. The raft has been credited with saving 230 lives in the last five years. It has found wide acceptance with operators of fishing boats, pleasure craft and other vessels. The Coast Guard is purchasing the rafts for use on its rescue helicopters and the Navy has a development program to adapt the system. The Coast Guard last year announced a proposed amendment of its regulations that would require large ballast chambers on inflatable life rafts.

Extraterrestrial life in the universe  

NASA Technical Reports Server (NTRS)

The possibility that life exists elsewhere in the universe, even in our own planetary system, has intrigued scientists, philosophers, and theologians for centuries. The spaceflight programs of NASA have provided much new information about our planetary neighbors and have put to rest some speculations about the existence of life on those planets or their satellites. However, there are still undetermined questions about the possibility of some form of life existing in the far distant past in our planetary system. Beyond our planetary system, the astronomical quest for scientific clues about life continues, largely via the radio telescope. Thus far there is no conclusive evidence. Here, some of the recent findings about our planetary neighbors are reviewed and the question about life elsewhere in the universe is addressed.

The Evolution of Complex Life  

NASA Technical Reports Server (NTRS)

In considering the probabilities that intelligent life might exist elsewhere in the Universe, it is important to ask questions about the factors governing the emergence of complex living organisms in the context of evolutionary biology, planetary environments and events in space. Two important problems arise. First, what can be learned about the general laws governing the evolution of complex life anywhere in space by studying its history on the Earth? Second, how is the evolution of complex life affected by events in space? To address these problems, a series of Science Workshops on the Evolution of Complex Life was held at the Ames Research Center. Included in this paper are highlights of those workshops, with particular emphasis on the first question, namely the evolution of complex extraterrestrial life.

The possibility of extraplanetary disturbances such as, meteorite and comet bombardments, and supernova explosions, causing the elimination of preexisting life and allowing advanced life development is analyzed. The possible existence of different life cycles (genetic and reproductive strategies) on other planets is studied. The GAIA hypothesis (Lovelock, 1979) which states living things modify the global environment to their own advantage is examined. The improved identification of habitable planetary environments and the possible existence of a form of extraterrestrial intelligent life is discussed.

Life: past, present and future  

NASA Technical Reports Server (NTRS)

Molecular methods of taxonomy and phylogeny have changed the way in which life on earth is viewed; they have allowed us to transition from a eukaryote-centric (five-kingdoms) view of the planet to one that is peculiarly prokarote-centric, containing three kingdoms, two of which are prokaryotic unicells. These prokaryotes are distinguished from their eukaryotic counterparts by their toughness, tenacity and metabolic diversity.

Life: past, present and future.  

PubMed Central

Molecular methods of taxonomy and phylogeny have changed the way in which life on earth is viewed; they have allowed us to transition from a eukaryote-centric (five-kingdoms) view of the planet to one that is peculiarly prokarote-centric, containing three kingdoms, two of which are prokaryotic unicells. These prokaryotes are distinguished from their eukaryotic counterparts by their toughness, tenacity and metabolic diversity. Realization of these features has, in many ways, changed the way we feel about life on earth, about the nature of life past and about the possibility of finding life elsewhere. In essence, the limits of life on this planet have expanded to such a degree that our thoughts of both past and future life have been altered.

The Role of Bundle Sheath Extensions and Life Form in Stomatal Responses to Leaf Water Status1[W][OA  

PubMed Central

Bundle sheath extensions (BSEs) are key features of leaf structure with currently little-understood functions. To test the hypothesis that BSEs reduce the hydraulic resistance from the bundle sheath to the epidermis (rbe) and thereby accelerate hydropassive stomatal movements, we compared stomatal responses with reduced humidity and leaf excision among 20 species with heterobaric or homobaric leaves and herbaceous or woody life forms. We hypothesized that low rbe due to the presence of BSEs would increase the rate of stomatal opening (V) during transient wrong-way responses, but more so during wrong-way responses to excision (Ve) than humidity (Vh), thus increasing the ratio of Ve to Vh. We predicted the same trends for herbaceous relative to woody species given greater hydraulic resistance in woody species. We found that Ve, Vh, and their ratio were 2.3 to 4.4 times greater in heterobaric than homobaric leaves and 2.0 to 3.1 times greater in herbaceous than woody species. To assess possible causes for these differences, we simulated these experiments in a dynamic compartment/resistance model, which predicted larger Ve and Ve/Vh in leaves with smaller rbe. These results support the hypothesis that BSEs reduce rbe. Comparison of our data and simulations suggested that rbe is approximately 4 to 16 times larger in homobaric than heterobaric leaves. Our study provides new evidence that variations in the distribution of hydraulic resistance within the leaf and plant are central to understanding dynamic stomatal responses to water status and their ecological correlates and that BSEs play several key roles in the functional ecology of heterobaric leaves.

Serpentinization and Life  

NASA Astrophysics Data System (ADS)

The serendipitous discovery of the Lost City Hydrothermal Field at 30N on the Mid-Atlantic Ridge significantly changed our views about where and how life is sustained on our planet. Investigation of this site shows that it is like no other yet discovered, hosting carbonate chimneys that tower up to 60 m above the seafloor. The field rests on 1-2 my old crust, at a water depth of 800 m and is underlain by variably deformed and altered peridotite with lesser gabbro. An intense interdisciplinary field program in 2003 and a follow-on investigation in 2005 show that geological, biological, and chemical processes are strongly intertwined at this site. Serpentinization reactions in the subsurface produce pH 9-11, 40- 91° C fluids enriched in methane, hydrogen, and other hydrocarbons. Mixing of the high pH fluids with seawater forms nearly monomineralic towers of calcite, aragonite, and brucite. In contrast to the rich diversity of microorganisms typically found in black smoker environments, the warm, porous interiors of the chimneys are dominated by a single phylotype of organisms related to Methanosarcinales, which may be capable of both methane oxidation and production. Other microbes, including an organism related to an anaerobic methane-oxidizing phylotytpe (ANME-1) are present in moderate temperature environments such as the flanges (40° C to 70° C), where there is sustained mixing of pure vent fluids and seawater. They are also present in cool carbonate vein environments (<40° C) that cut the serpentinite bedrock. Bacterial colonies grow on the outside of diffusely venting chimneys where they form white to light grey filamentous strands several centimeters in length. Based on 16S rDNA clone libraries there is a relatively high diversity of organisms in these zones that include Eubacteria as well as Archaea. In contrast to the dense macrofaunal assemblages that typify most known high-temperature vent environments, the biomass at Lost City is much smaller. The animals that live within the pores and small cavities on the outsides of the chimneys are typically <1 cm in size, with transparent to translucent shells that make them very difficult to see in the field. These animals include a variety of gastropods, polychaetes, and amphipods. Rare, larger animals include crabs, shrimp, sea urchins, eels, and a diverse array of corals. Current assessment at Lost City shows that 58% of the fauna are endemic to this vent environment. The discovery of seafloor hydrothermal ecosystems that do not require magmatic heat may have important implications in our search for life on other planets. The certainty that water exists, and has existed, on Mars where there is good evidence for rocks rich in olivine, and the presence of a liquid ocean on Europa, raises the question of whether systems similar to the Lost City Hydrothermal Field may be present (or were once present) elsewhere in the solar system.

Energy: It is life  

SciTech Connect

The relationships that seem to exist between energy and man are presented in this paper. Habitually, social coefficients are connected to the gross domestic product; some parameters with correlations are: birth rate, infant mortality rate, death rate, literacy, etc. Along with energy these define the optimal energy consumption per capita; the author presents the correlation between these parameters and energy consumed per capita. There exists a high correlation between energy consumption per capita and gross domestic product per capita. The set of parameters considered are correlated with similar values relative to these two parameters. Using data collected on a group of the different countries of the world, a table of 165 countries and 22 variables has been drawn up. From the [Country x variable] matrix, a correlation table is calculated and a factorial analysis is applied to this matrix. The first factorial plan comprises 57% of the information contained in this table. Results from this first factorial plan are presented. These parameters are analyzed: influence of a country's latitude on its inhabitants' consumption; relationship between consumed energy and gross domestic product; women's fertility rate; birth rate per 1000 population; sex ratio; life expectancy at birth; rate of literacy; death rate; population growth rate. Finally, it is difficult to define precise criteria for: an optimal distribution of population according to age, but with a power consumed of above 300 W per capita, the population becomes younger; the birth rate per 1000 population; the total fertility rate per woman; the population growth rate. The authors determine that optimal energy is approximately between 200 W and 677 W inclusive.

Charting Ingredients for Life  

NASA Technical Reports Server (NTRS)

[figure removed for brevity, see original site] Figure 1: Spectrum Charts Light from a Faraway Galaxy

This graph, or spectrum, charts light from a faraway galaxy located 10 billion light years from Earth. It tracks mid-infrared light from an extremely luminous galaxy when the universe was only 1/4 of its current age.

Spectra are created when an instrument called a spectrograph spreads light out into its basic parts, like a prism turning sunlight into a rainbow. They reveal the signatures, or 'fingerprints,' of molecules that make up a galaxy and contribute to its light.

Spitzer's infrared spectrometer identified characteristic fingerprints of complex organic molecules called polycyclic aromatic hydrocarbons, illustrated in the artist's concept in the inset. These large molecules comprised of carbon and hydrogen, are considered among the building blocks of life.

Scientists determined it took 10 billion years for photons from this galaxy to reach Spitzer's infrared eyes. These complex carbon and hydrogen molecules are from a young galaxy which is undergoing intense star formation, at the time the universe was only 3.5 billion years old.

These distant galaxies with enormous amounts of gas being converted into young stars are some of the most luminous objects in the sky. Enshrouded by dust, they are only faint, inconspicuous little dots in optical images. They are as bright as 10 trillion suns put together and 10 times brighter than starburst galaxies seen in our local universe.

This prompts a fascinating question as to what physical process is driving such enormous energy production in these galaxies when the universe is so young.

These data were taken by Spitzer's infrared spectrograph in August and September 2004.

Lubricant effects on bearing life  

NASA Technical Reports Server (NTRS)

Lubricant considerations for rolling-element bearings have within the last two decades taken on added importance in the design and operation of mechanical systems. The phenomenon which limits the useful life of bearings is rolling-element or surface pitting fatigue. The elastohydrodynamic (EHD) film thickness which separates the ball or roller surface from those of the raceways of the bearing directly affects bearing life. Chemical additives added to the lubricant can also significantly affect bearings life and reliability. The interaction of these physical and chemical effects is important to the design engineer and user of these systems. Design methods and lubricant selection for rolling-element bearings are presented and discussed.

Potential Habitats for Exotic Life Within the Life Supporting Zone  

NASA Astrophysics Data System (ADS)

Questions like "Are we alone in the universe?", "How unique is Earth as a planet?" or "How unique is water-based life in the universe?" still are nowhere near of being answered. In recent years, discussions on these topics are more and more influenced by questions whether water is really the only possible solvent, or which conditions are necessary for life to evolve in planetary habitats. A change in our present geocentric mindset on the existence of life is required, in order to address these new questions [see also 1]. In May 2009 a new research platform at the University of Vienna was initiated in order to contribute to the solution of these questions. One task is to find essential biomarkers relevant to the problem of the detection of exotic life. In this context exotic life means: life, which is not necessarily based on a double bond between carbon and oxygen (C=O) and not on water as the only possible solvent. At present little is known about metabolistic systems, which are not based on C=O or on metabolisms which are operative in alternative solvents and a high effort of future laboratory work is necessary to open this window for looking for exotic life. To address the whole spectrum of life the concept of a general life supporting zone is introduced in order to extend the classical habitable zone (which is based on liquid water on a planetary surface, [2]). The life supporting zone of a planetary system is composed of different single "habitable zones" for the liquid phases of specific solvents and composites between water and other solvents. Besides exoplanetary systems which seem to be the most promising place for exotic life in our present understanding, some potential places could also exist within our Solar System and habitats like the subsurface of Enceladus, liquid ethane/methane lakes on Titan or habitable niches in the Venus atmosphere will also be taken into account. A preliminary list of appropriate solvents and their abundances in the Solar System and beyond have been compiled. Dynamical investigations (related to the interior of superearths), but also heat transport regimes and potential cycles with exotic solvents as well as tidal heating processes and their influence on the thermal regime of the planets will help to define the regions of potential exotic life more precisely. Atmospheric and subsurface cycles which can take place in such habitats as well as cloud and droplet formation with and without cloud nuclei cores will further extend our knowledge on mechanisms relevant for the stability of these systems. Finally the question of suitable biomarkers, which can enable the observation of exotic habitats and their potential life forms will be considered in the research platform. In this context a special topic is also the bandwidth of photosynthesis: how is the influence of different atmospheric gases and what are the environment conditions for the chemical reactions of photosynthesis? First preliminary results for the life supporting zones of selected planetary systems will be presented.

Developing a reproductive life plan.  

PubMed

The purpose of this article is 2-fold: to emphasize the importance of a reproductive life plan and to define its key elements. We review the 2006 recommendations from the Centers for Disease Control and Prevention (CDC) regarding ways to improve the delivery of preconception health care to women in the United States, with particular focus on encouraging individual reproductive responsibility throughout the life span and on encouraging every woman to develop a reproductive life plan. We propose recommendations for the content of a reproductive life plan and explore ways to incorporate the guidelines from the CDC into clinical practice. By encouraging women to consider their plans for childbearing before they become pregnant, clinicians have the opportunity to influence behavior before pregnancy, which may decrease the incidence of unintended pregnancies and adverse pregnancy outcomes.

On the decomposition of life expectancy and limits to life.  

PubMed

Life expectancy is a measure of how long people are expected to live and is widely used as a measure of human development. Variations in the measure reflect not only the process of ageing but also the impacts of such events as epidemics, wars, and economic recessions. Since 1950, the influence of these events in the most developed countries has waned and life expectancy continues to lengthen unabated. As a result, it has become more difficult to forecast long-run trends accurately, or identify possible upper limits. We present new methods for comparing past improvements in life expectancy and also future prospects, using data from five developed, low-mortality countries. We consider life expectancy in 10-year age intervals rather than over the remaining lifetime, and show how natural limits to life expectancy can be used to extrapolate trends. We discuss the implications and compare our approach with other commonly used methods. Supplementary material for this article is available at: http://dx.doi.org/10.1080/00324728.2014.972433.

Integrating Varieties of Life Course Concepts  

PubMed Central

A body of work referred to as the “life course” framework (also known as “life course theory,” the “life course paradigm,” and the “life course perspective”) has been increasingly used to motivate and justify the examination of the relationships among variables in social and behavioral science, particularly in the study of population health and aging. Yet, there is very little agreement on what some of these concepts mean, and there is hardly any agreement on what the “life course” is. This article focuses on the different ways in which the concept of “life course” is used in the contemporary study of aging and human development, particularly with regard to health and well-being. Clarification is given for how “life course” is distinguished from “life span” and “life cycle,” among other “life” words. This work reviews the conceptual literature on the life course, beginning with its formative years in the 1960s and 1970s, through to the present time. Detailed research of several literatures across disciplines revealed five different uses of the term “life course”: (a) life course as time or age, (b) life course as life stages, (c) life course as events, transitions, and trajectories, (d) life course as life-span human development, and (e) life course as early life influences (and their cumulation) on later adult outcomes. To the extent the concept of life course has a multiplicity of meanings that are at variance with one another, this is problematic, as communication is thereby hindered. On the other hand, to the extent the concept of life course involves a rich tapestry of different emphases, this is a good thing, and the diversity of meanings should be retained. This paper proposes a conceptual integration based in part on Riley’s age stratification model that resolves the various meanings of life course into one general framework. Coupled with a demographic conceptualization of the life course, this framework embeds the concept of “life course” within a broader perspective of life-span development. This framework is proposed as an integrated perspective for studying the causes and consequences of “life course events and transitions” and understanding the manner by which “life events” and the role transitions they signify influence the life-span development of outcomes of interest across stages of the life cycle.

Searching for Alien Life Having Unearthly Biochemistry  

NASA Technical Reports Server (NTRS)

The search for alien life in the solar system should include exploring unearth-like environments for life having an unearthly biochemistry. We expect alien life to conform to the same basic chemical and ecological constraints as terrestrial life, since inorganic chemistry and the laws of ecosystems appear to be universal. Astrobiologists usually assume alien life will use familiar terrestrial biochemistry and therefore hope to find alien life by searching near water or by supplying hydrocarbons. The assumption that alien life is likely to be based on carbon and water is traditional and plausible. It justifies high priority for missions to search for alien life on Mars and Europa, but it unduly restricts the search for alien life. Terrestrial carbon-water biochemistry is not possible on most of the bodies of our solar system, but all alien life is not necessarily based on terrestrial biochemistry. If alien life has a separate origin from Earth life, and if can survive in an environment extremely different from Earth's, then alien life may have unearthly biochemistry. There may be other solvents than water that support alien life and other elements than carbon that form complex life enabling chain molecules. Rather than making the exploration-restricting assumption that all life requires carbon, water, and terrestrial biochemistry, we should make the exploration-friendly assumption that indigenous, environmentally adapted, alien life forms might flourish using unearthly biochemistry in many places in the solar system. Alien life might be found wherever there is free energy and a physical/chemical system capable of using that energy to build living structures. Alien life may be discovered by the detection of some general non-equilibrium chemistry rather than of terrestrial biochemistry. We should explore all the potential abodes of life in the solar system, including those where life based on terrestrial biochemistry can not exist.

An Aristotelian Account of Minimal Chemical Life  

NASA Astrophysics Data System (ADS)

This paper addresses the open philosophical and scientific problem of explaining and defining life. This problem is controversial, and there is nothing approaching a consensus about what life is. This raises a philosophical meta-question: Why is life so controversial and so difficult to define? This paper proposes that we can attribute a significant part of the controversy over life to use of a Cartesian approach to explaining life, which seeks necessary and sufficient conditions for being an individual living organism, out of the context of other organisms and the abiotic environment. The Cartesian approach contrasts with an Aristotelian approach to explaining life, which considers life only in the whole context in which it actually exists, looks at the characteristic phenomena involving actual life, and seeks the deepest and most unified explanation for those phenomena. The phenomena of life might be difficult to delimit precisely, but it certainly includes life's characteristic hallmarks, borderline cases, and puzzles. The Program-Metabolism-Container (PMC) model construes minimal chemical life as a functionally integrated triad of chemical systems, which are identified as the Program, Metabolism, and Container. Rasmussen diagrams precisely depict the functional definition of minimal chemical life. The PMC model illustrates the Aristotelian approach to life, because it explains eight of life's hallmarks, one of life's borderline cases (the virus), and two of life's puzzles.

Environmental control/life support  

NASA Technical Reports Server (NTRS)

It is pointed out that the life support systems technology used on projects Mercury, Gemini, Apollo, and Space Shuttle required an employment of expendables. Skylab was the only manned space project which made use of regenerable life support technology, taking into account the employment of a silica gel/molecular sieve for carbon dioxide removal. A number of investigations indicate that significant launch weight and volume as well as recurring cost savings can be realized by using regenerative life support processes for a Space Station. A number of developed regenerative processes are believed to be applicable to a Space Station. Aspects of air revitalization are discussed, taking into account carbon dioxide reduction, oxygen generation, trace contaminant control, temperature and humidity control, instrumentation, and nitrogen supply. Attention is also given to water reclamation, solid waste treatment, and future development and testing programs.

Augmenting Actual Life Through MUVEs  

E-print Network

The necessity of supporting more and more social interaction (and not only the mere information sharing) in online environments is the disruptive force upon which phenomena ascribed to the Web2.0 paradigm continuously bud. People interacting in online socio-technical environments mould technology on their needs, seamlessly integrating it into their everyday life. MUVEs (Multi User Virtual Environments) are no exception and, in several cases, represent the new frontier in this field. In this work we analyze if and how MUVEs can be considered a mean for augmenting communities (and more in general people) life. We trace a framework of analysis based on four main observations, and through these lenses we look at Second Life and at several projects we are currently developing in that synthetic world.

Tradeoffs in bacteriophage life histories  

PubMed Central

Viruses are the most abundant biological entities on the planet, yet most classical principles of evolutionary biology and ecology were not developed with viruses in mind. Here, the concept of biological tradeoffs, a fundamental tenet of life history theory, is examined in the context of bacteriophage biology. Specifically, several important parameters of phage life histories—replication, persistence, host range, and adsorption—are evaluated for tradeoffs. Available data indicate that replication rate is strongly negatively correlated with both persistence and host range, suggesting that the well-documented tradeoff in macroorganisms between offspring production and offspring quality also applies to phages. The biological tradeoffs that appear to characterize viruses’ life histories have potential importance for viral evolution, ecology, and pathogenesis. PMID:24616839

Pennsylvania life cycle costing manual  

SciTech Connect

Until the 1970s, it was commonplace for institutions and governments to purchase equipment based on lowest initial (first) costs. Recurring costs such as operational, maintenance, and energy costs often were not considered in the purchase decision. If an agency wanted to buy something, it published specifications and requested bids from several manufacturers. Often, the lowest bidder who met the specifications won the job, with no consideration given to the economic life of the equipment or yearly recurring costs such as energy and maintenance costs. The practice of purchasing based on lowest initial costs probably did not make good economic sense prior to 1970, and it certainly does not make good sense now. The wise person will consider all costs and benefits associated with a purchase, both initial and post-purchase, in order to make procurement decisions that are valid for the life of the equipment. This describes a method of financial analysis that considers all pertinent costs: life cycle costing (LCC).

Life extending control for rocket engines  

NASA Technical Reports Server (NTRS)

The concept of life extending control is defined. A brief discussion of current fatigue life prediction methods is given and the need for an alternative life prediction model based on a continuous functional relationship is established. Two approaches to life extending control are considered: (1) the implicit approach which uses cyclic fatigue life prediction as a basis for control design; and (2) the continuous life prediction approach which requires a continuous damage law. Progress on an initial formulation of a continuous (in time) fatigue model is presented. Finally, nonlinear programming is used to develop initial results for life extension for a simplified rocket engine (model).

Van Gogh and the life chart.  

PubMed

Adolf Meyer originally devised the life chart in order to chronologically document a person's major life events and significant illness experiences over his or her life span. It is the purpose of this report to update Meyer's life chart through the presentation of the life events and illnesses of the famous artist Vincent Van Gogh. Van Gogh's life illustrates significant early (predisposing) life stresses, as well as clusterings of stressful (precipitating) life events occurring proximal to the occurrence of his several illnesses. Through the use of a life chart an understanding of why an individual becomes ill at a particular time in their life is enlarged. In addition, a systematic basis for formulating prognosis becomes available. PMID:1286035

Life Sciences Data Archive (LSDA)  

NASA Technical Reports Server (NTRS)

In the early days of spaceflight, space life sciences data were been collected and stored in numerous databases, formats, media-types and geographical locations. While serving the needs of individual research teams, these data were largely unknown/unavailable to the scientific community at large. As a result, the Space Act of 1958 and the Science Data Management Policy mandated that research data collected by the National Aeronautics and Space Administration be made available to the science community at large. The Biomedical Informatics and Health Care Systems Branch of the Space Life Sciences Directorate at JSC and the Data Archive Project at ARC, with funding from the Human Research Program through the Exploration Medical Capability Element, are fulfilling these requirements through the systematic population of the Life Sciences Data Archive. This program constitutes a formal system for the acquisition, archival and distribution of data for Life Sciences-sponsored experiments and investigations. The general goal of the archive is to acquire, preserve, and distribute these data using a variety of media which are accessible and responsive to inquiries from the science communities.

Defining life: the virus viewpoint.  

PubMed

Are viruses alive? Until very recently, answering this question was often negative and viruses were not considered in discussions on the origin and definition of life. This situation is rapidly changing, following several discoveries that have modified our vision of viruses. It has been recognized that viruses have played (and still play) a major innovative role in the evolution of cellular organisms. New definitions of viruses have been proposed and their position in the universal tree of life is actively discussed. Viruses are no more confused with their virions, but can be viewed as complex living entities that transform the infected cell into a novel organism-the virus-producing virions. I suggest here to define life (an historical process) as the mode of existence of ribosome encoding organisms (cells) and capsid encoding organisms (viruses) and their ancestors. I propose to define an organism as an ensemble of integrated organs (molecular or cellular) producing individuals evolving through natural selection. The origin of life on our planet would correspond to the establishment of the first organism corresponding to this definition. PMID:20198436
