  7. Amoralist rationalism? A response to Joel Marks: commentary on "Animal abolitionism meets moral abolitionism: cutting the Gordian knot of applied ethics" by Joel Marks.

    PubMed

    Lederman, Zohar

    2014-06-01

    In a recent article, Joel Marks presents the amoralist argument against vivisection, or animal laboratory experimentation. He argues that ethical theories that seek to uncover some universal morality are in fact useless and unnecessary for ethical deliberations meant to determine what constitutes an appropriate action in a specific circumstance. I agree with Marks' conclusion. I too believe that vivisection is indefensible, both from a scientific and philosophical perspective. I also believe that we should become vegan (unfortunately, like the two philosophers mentioned by Marks, I too am still struggling to reduce my meat and dairy consumption). However, I am in the dark as to Marks' vision of normative deliberations in the spirit of amoralism and desirism. PMID:24744177

    USGS Publications Warehouse

    Waller, Roger M.

    1979-01-01

    A major fracture system in indurated sedimentary rocks forms a moderately extensive aquifer yielding 100-300 gallons per minute to wells 160 to 420 feet deep. Pumping-test data show that the fracture system is interconnected to distances more than 1,000 feet from the wells. Recharge occurs through overlying clayey till, and continuous pumping may induce recharge from surface-water sources. Chemical analyses indicate no water-quality problems. Systematic collection of data on pumpage , water level, and chemical quality could help to determine the long-term adequacy of the aquifer system. (Woodard-USGS)

  16. New frontiers in fibrotic disease therapies: The focus of the Joan and Joel Rosenbloom Center for Fibrotic Diseases at Thomas Jefferson University.

    PubMed

    Rosenbloom, Joel; Ren, Shumei; Macarak, Edward

    2016-04-01

    Fibrotic diseases constitute a world-wide major health problem, but research support remains inadequate in comparison to the need. Although considerable understanding of the pathogenesis of fibrotic reactions has been attained, no completely effective therapies exist. Although fibrotic disorders are diverse, it is universally appreciated that a particular cell type with unique characteristics, the myofibroblast, is responsible for replacement of functioning tissue with non-functional scar tissue. Understanding the cellular and molecular mechanisms responsible for the creation of myofibroblasts and their activities is central to the development of therapies. Critical signaling cascades, initiated primarily by TGF-β, but also involving other cytokines which stimulate pro-fibrotic reactions in the myofibroblast, offer potential therapeutic targets. However, because of the multiplicity and complex interactions of these signaling pathways, it is very unlikely that any single drug will be successful in modifying a major fibrotic disease. Therefore, we have chosen to examine the effectiveness of administration of several drug combinations in a mouse pneumoconiosis model. Such treatment proved to be effective. Because fibrotic diseases that tend to be chronic, are difficult to monitor, and are patient variable, implementation of clinical trials is difficult and expensive. Therefore, we have made efforts to identify and validate non-invasive biomarkers found in urine and blood. We describe the potential utility of five such markers: (i) the EDA form of fibronectin (Fn(EDA)), (ii) lysyl oxidase (LOX), (iii) lysyl oxidase-like protein 2 (LoxL2), (iv) connective tissue growth factor (CTGF, CCNII), and (v) the N-terminal propeptide of type III procollagen (PIIINP).

Before I could scoot my rear end to safety though, the shaking stopped and the building settled. The great East Coast quake was over.

  8. December 2014 HeartWeek issue of cardiology in the young: highlights of HeartWeek 2014: diseases of the cardiac valves from the foetus to the adult.

    PubMed

    Jacobs, Jeffrey P

    2014-12-01

    This December Issue of Cardiology in the Young represents the 12th annual publication generated from the two meetings that compose "HeartWeek in Florida". "HeartWeek in Florida", the joint collaborative project sponsored by the Cardiac Center at the Children's Hospital of Philadelphia, Pennsylvania, together with Johns Hopkins All Children's Heart Institute of Saint Petersburg, Florida, averages over 1000 attendees every year and is now recognised as one of the major planks of continuing medical and nursing education for those working in the fields of diagnosis and treatment of cardiac disease in the foetus, neonate, infant, child, and adult. "HeartWeek in Florida" combines the International Symposium on Congenital Heart Disease, organised by All Children's Hospital and Johns Hopkins Medicine and entering its 15th year, with the Annual Postgraduate Course in Pediatric Cardiovascular Disease, organised by The Children's Hospital of Philadelphia and entering its 18th year. This December, 2014 Issue of Cardiology in the Young features highlights of Johns Hopkins All Children's Heart Institute's 14th Annual International Symposium on Congenital Heart Disease, which was held at the Renaissance Vinoy Resort & Golf Club, Saint Petersburg, Florida, from 15-18 February, 2014. This Symposium was co-sponsored by The American Association for Thoracic Surgery (AATS) and had as its special focus " Diseases of the Cardiac Valves from the Fetus to the Adult ". We acknowledge the tremendous contributions made to paediatric and congenital cardiac care by Duke Cameron and Joel Brenner, and therefore we dedicate this December, 2014 HeartWeek Issue of Cardiology in the Young to them. Duke Cameron is Professor of Surgery at Johns Hopkins University and Cardiac Surgeon-in-Charge at The Johns Hopkins Hospital. Joel Brenner is Professor of Pediatrics at Johns Hopkins University and Director of the Taussig Heart Center at Bloomberg Children's Center, The Johns Hopkins Hospital. Together

  9. Depression, responsibility, and criminal defenses.

    PubMed

    Hannan, Barbara

    2005-01-01

    The concepts of voluntary action, agency, free will, and responsibility, while central to moral and legal institutions, are generally poorly understood. Philosophers of law such as H.L.A. Hart, Joel Feinberg, and Robert F. Schopp have contributed significantly to understanding of these concepts through their work on the foundations of criminal defenses, including excuses based on mental illness. In this paper, I summarize and present their valuable insights, in the context of an argument (influenced by personal experience) that clinical depression, even when non-psychotic, may in some cases constitute a legitimate excuse for criminal or otherwise immoral failures to act. PMID:15913778

  10. The history of cesarean technique.

    PubMed

    Lurie, Samuel; Glezerman, Marek

    2003-12-01

    Cesarean section has been practiced since ancient times. Unfortunately, no ancient medical documents describing the techniques for cesarean section are extant. In the early medieval period, cesarean section was usually performed by midwives. One of the first explicit instructions in medical literature on cesarean technique dates from about 1480 ce from southern Germany. We discuss the evolution of cesarean surgical technique and point up the contribution of many giants in the field of obstetrics and gynecology, such as Blundell, Frank, Harris, Joel-Cohen, Kehrer, Kerr, Lebas, Levret, Maylard, Pfannenstiel, Porro, Portes, and Sanger.

    Bodenheimer, Thomas

    2003-01-01

    The paper by Joel Weissman and colleagues addresses the increasingly important topic of the effects of direct-to-consumer advertising (DTCA) by pharmaceutical companies. The authors claim that their results should be reassuring to "those concerned about potential adverse health care consequences of DTCA". However, the study and analysis of the data are marred by several flaws that diminish the importance and relevance of the findings, including weakness in design, overgenerous interpretations, and failure to address key questions. Rather than informing the debate, the study amounts to little more than an advertisement for drug advertisements. PMID:14527241

    West, James W.; Burkett, Cecil G.; Levine, Joel S.

    2002-01-01

    In 1951, the four pages of the US Constitution, the Letter of Transmittal, the Bill of Rights and the Declaration of Independence, collectively called the 'Charters of Freedom,' were hermetically sealed individually in glass encasements. The atmosphere in the encasements consisted of a mixture of helium with water vapor at a relative humidity between 25 and 35% at room temperature. In 1998, Margaret Kelly of the National Archives and Records Administration (NARA), contacted Dr. Joel S. Levine at NASA Langley Research Center (LaRC) to request assistance in determining the chemical composition of the atmosphere inside the encasements. Several different Langley learns were assembled to address that request. each using a different measurement technique. This report describes the method and results of one team's relative humidity measurements on encasements containing pages 1 and 4 of the US Constitution, the Bill of Rights, and the Declaration of Independence performed at NARA, College Park.

  14. Human genetic enhancement: is it really a matter of perfection? A dialog with Hanson, Keenan, and Shuman.

    PubMed

    Taboada, Paulina

    1999-08-01

    The author reviews the arguments made by Mark Hanson, James Keenan, S.J., and Joel Shuman in this issue. In the first section, she argues that they offer a significant contribution toward an understanding of the inner logic of a new trend in contemporary medicine, genetic engineering. However, she criticizes the authors for relying excessively on procedural guidelines and for failing to bring the practical realities of medicine and technology to bear on theory. She argues that more concrete guidelines, which are ultimately grounded in a Christian conception of the person and on the commandment to love, are necessary. Writing from the Roman Catholic perspective, the author argues that the distinction between genetic enhancement and gene therapy is essential, despite the criticisms which have been offered of this distinction. Understanding this distinction will be critical for identifying as licit only those forms of genetic manipulation which respect the dignity of the human person. PMID:11658192

    The Sixth Annual Vaccine Renaissance Conference, hosted by the Institute for Immunology and Informatics (iCubed) at the University of Rhode Island (URI), took place on October 15–17, 2012. This conference provides a forum for the review of current progress in the discovery and development of vaccines, and creates an environment for the exchange of ideas. Dr. Joel McCleary opened the conference with a warning about the importance of preparing for well-defined biowarfare threats, including tularemia and Staphylococcal enterotoxin B. Following the keynote address, sessions explored biodefense and preparation for pandemic and biowarfare threats; vaccines for emerging and re-emerging neglected tropical diseases; animal vaccines and human health; and vaccine vectors and the human microbiome. In this issue of Human Vaccines and Immunotherapeutics, seven Vaccine Renaissance Conference speakers will showcase their work; here, we describe a few of the conference highlights. PMID:23732897

    NASA Technical Reports Server (NTRS)

    1973-01-01

    This chart describes the Skylab student experiment ED-61, Plant Growth, and experiment ED-62, Plant Phototropism. Two similar proposals were submitted by Joel G. Wordekemper of West Point, Nebraska, and Donald W. Schlack of Downey, California. Wordekemper's experiment (ED-61) was to see how the lack of gravity would affect the growth of roots and stems of plants. Schlack's experiment (ED-62) was to study the effect of light on a seed developing in zero gravity. The growth container of the rice seeds for their experiment consisted of eight compartments arranged in two parallel rows of four. Each had two windowed surfaces to allow periodic photography of the developing seedlings. In March 1972, NASA and the National Science Teachers Association selected 25 experiment proposals for flight on Skylab. Science advisors from the Marshall Space Flight Center aided and assisted the students in developing the proposals for flight on Skylab.

  17. [The Misgav Ladach method for cesarean section].

    PubMed

    Habek, Dubravko; Kulas, Tomislav; Karsa, Matija

    2007-04-01

    The Misgav Ladach method for cesarean section is based on the principles of surgical minimalism. This is based on the Joel Cohen laparotomy, somewhat higher than the Pfannenstiel incision. Subcutaneous tissue is left undisturbed apart from the midline, rectus muscles are separated by pulling. The peritoneum is opened by stretching with index fingers. The hysterotomy is closed with one layer extraendometrial continuous absorbable stitches (Vicryl), and the visceral and parietal peritoneal layers are left open. Fascia is stitched with a continuous synthetic absorbable stitch. The skin is closed with intracutaneous resorptive suture or metallic stapler sutures. The Misgav Ladach method is restrictive in the use of sharp instruments preferring manual manipulation: it gives faster recovery, shorter period to normal bowel function, less peritoneal adhesions and less scarring in the abdominal layers, less use of postoperative antibiotics, analgesics and antipyretics, and a shorter anesthetic and operative time. It is ideal for emergency and planned cesarean section. PMID:17585470

  18. What veterinary practice managers can learn from other health care professions.

    PubMed

    Wood, F

    1996-02-01

    Joel Barker, a noted futurist, points out that the best ideas usually come from outside an industry or profession. As a management consultant, I often get new ideas from industries completely unrelated to my clients' industry. For example, companies interested in offering outstanding customer service might study Nordstrom's, L.L. Bean, or Lexus. Those interested in world class distribution might research Federal Express or United Parcel Service. Airlines, trying to minimize downtime of jets at the terminal, learn secrets from Indianapolis 500 pit crews. Similarly, in observing optometrists and dentists, there are valuable lessons for veterinarians. Dentists identified a business model or organizational structure that generates healthy profits. Independent optometrists experienced the onslaught of intense competition from huge corporate players and weathered the storm. The veterinary profession is not so unique. By studying other professions, we need not recreate the wheel. PMID:8778948

    The following two-part article is Dr. Mattison's reflections on his experiences with Albert Schweitzer at Hôpital du Dr. Albert Schweitzer, Lambaréné, Gabon, Africa, from December of 1961 through April of 1963. Gabon, once a part of French Equatorial Africa, is located on the west coast of Africa. Dr. Mattison has chronicled and provided unique insight into Dr. Schweitzer's career and beliefs through both written text and photography. The photographs accompanying this article were taken by Joel and Jean Mattison, and are here borrowed from the archives at Princeton Theological Seminary. These and other photographs were recently complied in "Visiting Hours at Lambaréné: Photographic Reminiscences of Albert Schweitzer, 1961-1963" for an exhibition for the International Albert Schweitzer Colloquium in August of 1990 at the United Nations, in commemoration of the silver anniversary of Schweitzer's death.

    PubMed

    Ortega, Lorena Bettancourt; Ventura, Carla Arena

    2013-12-01

    The objective of this study was to determine the experience of nurses who care for drug-dependent patients at a medical service of a public hospital in Chile. This is a qualitative study of phenomenological trajectory according to Martin Heidegger's framework. The study question was, What is the experience of taking care of drug-dependent patients admitted to your service? Nurses' reports were based on the concept of situated phenomenon reference by Joel Martins After analyzing the interviews, we identified three themes that expressed this phenomenon: speaking about the drug-dependent patient, taking care of patients in an adverse environment, and dispelling the fear of care. This study shows the need to train health care professionals on dealing with alcohol- and drug-dependent patients in order to overcome prejudices and improve care delivered to these patients.

    The choice of the type of abdominal incision performed in caesarean delivery is made chiefly on the basis of the individual surgeon’s experience and preference. A general consensus on the most appropriate surgical technique has not yet been reached. The aim of this systematic review of the literature is to compare the two most commonly used transverse abdominal incisions for caesarean delivery, the Pfannenstiel incision and the modified Joel-Cohen incision, in terms of acute and chronic post-surgical pain and their subsequent influence in terms of quality of life. Electronic database searches formed the basis of the literature search and the following databases were searched in the time frame between January 1997 and December 2013: MEDLINE, EMBASE Sciencedirect and the Cochrane Library. Key search terms included: “acute pain”, “chronic pain”, “Pfannenstiel incision”, “Misgav-Ladach”, “Joel Cohen incision”, in combination with “Caesarean Section”, “abdominal incision”, “numbness”, “neuropathic pain” and “nerve entrapment”. Data on 4771 patients who underwent caesarean section (CS) was collected with regards to the relation between surgical techniques and postoperative outcomes defined as acute or chronic pain and future pregnancy desire. The Misgav-Ladach incision was associated with a significant advantage in terms of reduction of post-surgical acute and chronic pain. It was indicated as the optimal technique in view of its characteristic of reducing lower pelvic discomfort and pain, thus improving quality of life and future fertility desire. Further studies which are not subject to important bias like pre-existing chronic pain, non-standardized analgesia administration, variable length of skin incision and previous abdominal surgery are required.

    A collaborative approach to communicating our amazing science. RAL Space at the Rutherford Appleton Lab, has initiated a unique collaboration with a team of award-winning performing artists with the aim of making space science research engaging and accessible to a wide audience. The collaboration has two distinct but connected strands one of which is the development of a contemporary dance work inspired by solar science and including images and data from the Space Physics Division of STFC RAL Space. The work has been commissioned by Sadler's Wells, one of the world's leading dance venues. It will be created by choreographer Alexander Whitley, video artist Tal Rosner and composers Ella Spira and Joel Cadbury and toured throughout the UK and internationally by the Alexander Whitley Dance Company (AWDC). The work will come about through collaboration with the work of the scientists of RAL Space and in particular the SOHO, CDS and STEREO missions, taking a particular interest in space weather. Choreographer Alexander Whitley and composers Ella Spira and Joel Cadbury will take their inspiration from the images and data that are produced by the solar science within RAL Space. Video artist Tal Rosner will use these spectacular images to create an atmospheric backdrop to accompany the work, bringing the beauty and wonder of space exploration to new audiences. Funding for the creation and touring of the work will be sought from Arts Council England, the British Council, partner organisations, trusts and foundations and private donors.The world premiere of the work will take place at Sadler's Wells in June 2017. It will then tour throughout the UK and internationally to theatres, science conferences and outreach venues with the aim of bringing the work of STFC RAL Space and the science behind solar science and space weather to new audiences. An education programme will combine concepts of choreography and space science aimed at young people in year 5 Key Stage 2 and be

    Joel Barker has been talking about the future for a long time past. His message: Change happens. Change happens as paradigms shift--the way we picture the universe shifts, and life is different. Relationships and values change their meaning. And because they mean something different, we change them. Barker's question is: How do you manage this change? How do you get ahead of it, and not lag behind it? How do you become its partner and not its victim? These are challenging questions, and hundreds of corporations have invited Barker to come ask them. His client list ranges over much of the Fortune 500--from IBM and DuPont to Honeywell, Boeing, and Gulf Oil--and it includes such healthcare clients as Merck, Upjohn, the Mayo clinics, and the Sisters of Charity. Barker has worked with these questions for the past 17 years, first as director of the pioneering Future Studies Department of the Science Museum of Minnesota, then as president of Infinity Limited, Inc. He has put his answers into a video, "Discovering the Future," and two books, the 1985 Discovering the Future: The Business of Paradigms, and the new Future Edge: The Paradigm Principles Guide for the '90s. We spent a recent morning talking with him about what a paradigm is, and what happens when a paradigm shifts. PMID:10115418

    The automation of various parts of multiple--cycle direct oxide reduction (MCDOR) at LANL`s NMT-3 was the goal of this research and development activities. In particular, originally the following goals were assigned to the author by the NMT-3 technical staff leaders (Greg Bird, Jim McNeese, Joel Williams): (1) Design and fabricate an automation set up; (2) Step-wise automation is preferred; (3) Step 1 involves automatic metering and mixing of powders; and (4) Step 2-automatic transport of powder to furnace location The initial task assigned in May 91 was to get the appropriate design developed and order equipment and parts to automatically weight powders. In fact the work statement read {open_quotes}Create an experimental automation set up in the ME Department at UNM to automatically weigh powders using an electronic balance. Further, design the set up such that the electronic balance is reprogrammable for specific weight set points. Thus, when a set point in weight is reached by means of a vibratory feeder feeding a container on the balance, the electronic balance will send an electronic signal out to switch off the vibratory feeder{close_quotes}.

    Summary: Combinatorial assembly of DNA elements is an efficient method for building large-scale synthetic pathways from standardized, reusable components. These methods are particularly useful because they enable assembly of multiple DNA fragments in one reaction, at the cost of requiring that each fragment satisfies design constraints. We developed BioPartsBuilder as a biologist-friendly web tool to design biological parts that are compatible with DNA combinatorial assembly methods, such as Golden Gate and related methods. It retrieves biological sequences, enforces compliance with assembly design standards and provides a fabrication plan for each fragment. Availability and implementation: BioPartsBuilder is accessible at http://public.biopartsbuilder.org and an Amazon Web Services image is available from the AWS Market Place (AMI ID: ami-508acf38).

    Biodiversity conservation has been criticized for undermining or ignoring social well-being. Currently efforts to mutually promote social justice, rural development, and biodiversity conservation, which have been contentious and yielded mixed results, continue to spread despite a general dearth of effective management strategies. We contend that social and economic concerns should be integral to conservation planning and propose that the scale of these phenomena is also critical. To evaluate the merit of this proposal, we adopted and expanded a conservation management strategy framework developed by Joel Heinen and examined how population density, economic disparity, and ethnic heterogeneity vary spatially surrounding 2 contrasting protected areas in East Africa: Kibale National Park in Uganda and Tarangire National Park in Tanzania. Analyses of demographic, wealth, and ethnicity data from regional censuses and household surveys conducted in 2009 and 2010 indicated that choice of scale (landscape or community) changed the management strategies recommended by the model. Therefore, "several small" people-park management strategies varying around a given protected area may be more appropriate than a "single large" people-park strategy applied across an entire protected area. Correspondingly, scale adjusted Heinen recommendations offered new strategies for effective conservation management within these human landscapes not incorporated in current in situ management plans.

  9. Effects of increased pumpage on a fractured-bedrock aquifer system in central Orange County, New York

    1985-01-01

    The bedrock in central Orange County consists of highly indurated siltstone, shale, and conglomerate containing two major fault systems and extensive fracturing; it is overlain by 50 to 100 feet of till. The fracturing permits unusually high well yields. Wells tapping the bedrock yield 75 to 200 gallons per minute; those tapping bedrock in adjacent areas yield only a few tens of gallons per minute. The bedrock aquifer is recharged mainly by percolation of water from precipitation through the till. In 1983, the U.S. Geological Survey studied the hydrologic effects of increased pumpage on the fractured bedrock aquifer system near the Village of Kiryas Joel, in the Town of Monroe. Water levels were measured in several wells in the village 's two well fields from February to October 1983, and pumpage data from the same period were tabulated. Water levels responded to variations in both pumpage and precipitation. Pumping tests and water levels in the southeastern well field in 1983 had no effect on the northwestern well field. An observation well between the two fields shows about 20 feet of seasonal fluctuation from recharge and the effects of pumping at the northwestern well field. Aquifer-test data indicate a transmissivity of 900 feet squared per day and a storage coefficient of 0.0001. (USGS)

    In a series of alkoxy- and chloro-substituted methyl phosphonites, the Arbuzov reaction is a preparative method for the synthesis of new types of functionally substituted methyl phosphinates. The Arbuzov reaction takes a new pathway in the case of dialkoxymethyl phosphonites, in which the phosphorus-carbon bond is ruptured at the stage where a quasiphosphonium compound forms, producing alkoxycarbonyl phosphonites that have not been available before. The IR spectra were obtained on UR-20 and IKS-22 instruments in a thin layer (NaCL). The PMR spectra were taken on a Tesla BS-497 spectrometer (100 MHz) in C/sub 6/D/sub 6/ and CDCl/sub 3/ solutions (20 to 30% concn.), with TMS as standard. The /sup 13/C NMR spectrum of phosphonite (XI) was obtained on a Varian FT-80A spectrometer (20 MHz) in an 80% solution in C/sub 6/D/sub 6/ and with TMS as standard. The /sup 31/P NMR spectra were obtained on JEOL 6-50OHL (24.3 MHz), Varian FT-80A (32.2 MHz), and JOEL FX-100 (42 MHz) spectrometers with an 85% solution of H/sub 3/PO/sub 4/ in D/sub 2/O as standard.

    Cosmology is in the midst of a scientific revolution that is establishing its lasting foundations. The good agreement between many different sorts of observations and the predictions of the now-standard Lambda Cold Dark Matter (LCDM) theory gives us hope that this is humanity's first picture of the history of the universe as a whole that might actually be true. An unexpected feature of this new picture is that we humans appear to be central or special in many ways -- for example, we are made of the rarest stuff in the universe (stardust); we are intermediate in size between the smallest possible size (the Planck length) and the largest size (the cosmic horizon); and we are living at a pivotal time: the period in the history of the universe when its expansion began to accelerate rather than slow down, and in the middle of the ten-billion-year lifetime of our solar system and of the billion year most habitable period of our planet, and at what must be the end of the exponential growth of human impact on the earth. This talk will review key observations that support modern cosmology, describe some symbolic ways of understanding the modern cosmos, and discuss some possible implications of a cosmic perspective for our 21st century worldview. Based on a new book, The View from the Center of the Universe: Discovering Our Extraordinary Place in the Cosmos, by Joel R. Primack and Nancy Ellen Abrams (Riverhead Books, April 2006).

  13. Harnessing the complexity of gene expression data from cancer: from single gene to structural pathway methods

    PubMed Central

    2012-01-01

    High-dimensional gene expression data provide a rich source of information because they capture the expression level of genes in dynamic states that reflect the biological functioning of a cell. For this reason, such data are suitable to reveal systems related properties inside a cell, e.g., in order to elucidate molecular mechanisms of complex diseases like breast or prostate cancer. However, this is not only strongly dependent on the sample size and the correlation structure of a data set, but also on the statistical hypotheses tested. Many different approaches have been developed over the years to analyze gene expression data to (I) identify changes in single genes, (II) identify changes in gene sets or pathways, and (III) identify changes in the correlation structure in pathways. In this paper, we review statistical methods for all three types of approaches, including subtypes, in the context of cancer data and provide links to software implementations and tools and address also the general problem of multiple hypotheses testing. Further, we provide recommendations for the selection of such analysis methods. Reviewers This article was reviewed by Arcady Mushegian, Byung-Soo Kim and Joel Bader. PMID:23227854

    Unowsky, Joel (Northwestern University Medical School, Chicago, Ill.), and Martin Rachmeler. Mechanisms of antibiotic resistance determined by resistance-transfer factors. J. Bacteriol. 92:358–365. 1966.—This study was concerned with the mechanism of expression of drug resistance carried by resistance-transfer (R) factors of two types: fi− (negative fertility inhibition) and fi+ (positive fertility inhibition). The levels of drug resistance determined by R factors used in this study were similar to those reported by other investigators. A new finding was that Escherichia coli carrying the fi− episome was resistant to 150 to 200 μg/ml of streptomycin. The growth kinetics of R factor-containing cells were similar in the presence or absence of streptomycin, chloramphenicol, and tetracycline, but a period of adaptation was necessary before cells began exponential growth in the presence of tetracycline. By use of radioactive antibiotics, it was shown that cells containing the fi− episome were impermeable to tetracycline and streptomycin, whereas cells containing the fi+ episome were impermeable only to chloramphenicol. Cell-free extracts from fi+ and fi− cells were sensitive to the antibiotics tested in the polyuridylic acid-stimulated incorporation of phenylalanine into protein. PMID:16562121

    In a statement to several Senators, an Office of Technology Assessment analyst says the Superfund program to clean up abandoned hazardous waste sites is likely to be a multidecade effort, encompassing at least 10,000 sites, and costing $50 billion to $100 billion. But throwing vast sums of money at the Environmental Protection Agency now would be throwing money down a black hole, says OTA senior associate Joel S. Hirschhorn. He says this is the first time OTA, the research arm of Congress, has put a price tag on the cost of cleaning up the disposal mistakes of the past. But he is quick to add that OTA's staggering estimate of total cleanup costs should in no way influence funding levels in pending bills to reauthorize Superfund. Hirschhorn says EPA is not now capable of spending efficiently more than $1 billion per year. And by so saying, he reaffirmed what EPA has been declaring all year to House and Senate committees working on legislation to reauthorize Superfund before the November elections and one year before it expires in 1985.

    There are more and more indications that contributions to research in science and engineering are stratified. A few influential papers distinguish themselves among large numbers of quite ordinary papers. The most influential papers are typically pioneering, commonly marking the beginning of some important new research strand and encouraging follow-on papers. In many respects, the pattern of activity in a research strand follows a life-cycle growth curve or a business product cycle. Our analysis of papers published in Water Resources Research shows that as a strand matures, papers lose their impact. In many respects, business is ahead of science because the process of innovation is accepted as a normal business practice for successful companies. While researchers acknowledge the importance of innovation, the topic is not commonly considered as something that one would learn or even talk about. Our paper here explores some of the lessons on designing for innovation, which come from the world of business. For example, leadership gurus like Tom Peters have much to say about the need for purposefully destroying successful enterprises, in other words, providing the motivation to adjust the focus of research to new strands or directions. Writers like Joel Barker let us understand ways to innovate within research strands. A more formalized understanding of the innovation process in hydrology will yield important dividends.

    Hyer, J R

    2001-01-01

    Joel R. Hyer investigates health conditions on one Indian reservation in Southern California during the first two decades of the twentieth century. Hyer contends that unsanitary conditions on the Pala Reservation actually facilitated the spread of diseases among local Cupeño, Luiseño, and Kumeyaay Indians. He also describes how the United States federal government employed doctors, field matrons, and others to promote good health and combat disease among Indians at Pala. The author asserts that, despite their altruistic intentions, some of these government workers attempted to discourage local indigenous peoples from consulting their shamans for medical attention - Native healers whose extensive knowledge of roots and herbs had cured many forms of illness for years. In addition, the teacher at the reservation's day school sought to prevent the spread of disease among her Indian pupils by exposing them to American modes of health care. Furthermore, Hyer maintains that one national health program, the "Save the Babies" campaign, was successful on the Pala Reservation because Indian mothers believed in it and followed specific guidelines to lower mortality rates among their own children. Throughout his essay, the author addresses the pressures of assimilation and acculturation that were so accute at this time in the United States. Hyer concludes by suggesting that many of his findings reflect broader health trends on Indian reservations throughout the United States during this period. PMID:14515872

    Since the early part of the nineteenth century, physicians from Boston have had a major impact on orthopaedics in America. Initially, the general surgeons such as John Ball Brown and his son, Buckminster had an impact on orthopaedics, but contributors such as Henry Bigelow and Charles Scudder added greatly to the knowledge and capacity for care. The first orthopaedic ward, Ward I, was located at the Massachusetts General Hospital and began the new era. Surgical treatment by orthopaedists began in the twentieth century with such contributors as Philip Wilson, EA Codman, Robert B. Osgood, Joel Goldthwait, Elliot Brackett, Robert Lovett, and Edward Bradford. These physicians not only treated patients at the Children's, Tufts University, Boston City, the Beth Israel, and the Massachusetts General Hospitals, but assumed the academic responsibilities of a major educational center. More recently the contributors to orthopaedics have included Marius Smith-Petersen, Otto Aufranc, Henry Banks, Edward Cave, Carter Rowe, Joseph Barr, and others who have created a spectacular program for education, research, and clinical care.

The impact was observed at near-infrared wavelengths, 2.3 microns. In the beginning of the movie, only part of the Southern hemisphere is visible with two former impact sites. The former impact site of Fragments P and Q appears on the left side. R hits this same spot. The movie covers a timespan of approximately half an hour. At 5:33 UT a first flash is detected just above the impact site, lasting for approximately 20 seconds. A second flash is detected about 20 seconds later, lasting for about a minute. Several minutes later the fireball becomes visible as a bright spot, increasing rapidly in intensity. Within a few minutes it is outshining the entire planet. The rise and fall in intensity takes about 8 minutes.

  1. A Defence of the Counterfactual Account of Harm.

    PubMed

    Purshouse, Craig

    2016-05-01

    In order to determine whether a particular course of conduct is ethically permissible it is important to have a concept of what it means to be harmed. The dominant theory of harm is the counterfactual account, most famously proposed by Joel Feinberg. This determines whether harm is caused by comparing what actually happened in a given situation with the 'counterfacts' i.e. what would have occurred had the putatively harmful conduct not taken place. If a person's interests are worse off than they otherwise would have been, then a person will be harmed. This definition has recently faced challenges from bioethicists such as John Harris, Guy Kahane and Julian Savulescu who, believing it to be severely flawed, have proposed their own alternative theories of the concept. In this article I will demonstrate that the shortcomings Harris, Kahane and Savulescu believe are present in Feinberg's theory are illusory and that it is their own accounts of harm that are fraught with logical errors. I maintain that the arguments presented to refute Feinberg's theory not only fail to achieve this goal and can be accommodated within the counterfactual account but that they actually undermine the theories presented by their respective authors. The final conclusion will be that these challenges are misconceived and fail to displace the counterfactual theory. PMID:26423790

    This article summarizes the proceedings of a symposium presented at the 2004 meeting of the Research Society on Alcoholism (RSA) in Vancouver, British Columbia, Canada. There were four presentations and a discussant. The symposium was co-chaired by Tina Zawacki and Jeanette Norris. The first presentation was made by Jeanette Norris, who found that alcohol consumption and preexisting alcohol expectancies affected women's hypothetical responses to a vignette depicting acquaintance sexual aggression. The second presentation was made by Joel Martell, who reported that alcohol-induced impairment of executive cognitive functioning mediated the effect of intoxication on men's perceptions of a sexual assault vignette. In the third presentation, Antonia Abbey found that the experiences of women whose sexual assault involved intoxication or force were more negative than were the experiences of women whose sexual assault involved verbal coercion. The fourth presentation was made by Tina Zawacki, who reported that men who perpetrated sexual assault only in adolescence differed from men who continued perpetration into adulthood in terms of their drinking patterns and attitudes toward women. William H. George discussed these findings in terms of their implications for theory development and prevention programming. PMID:15714049

    The tripeptide-copper complex glycyl-L-histidyl-L-lysine-Cu2+ (GHK-Cu) was first described as a growth factor for differentiated cells. Recent in vitro data showed that it possesses several properties of a potential activator of wound repair. We investigated the effects of GHK-Cu in vivo, using the wound chamber model described previously (Schilling, J.A., W. Joel, and M.T. Shurley, 1959. Surgery [St. Louis]. 46:702-710). Stainless steel wire mesh cylinders were implanted subcutaneously on the back of rats. The animals were divided into groups that received sequential injections into the wound chamber of either saline (control group) or various concentrations of GHK-Cu. At the end of the experiments, rats were killed, wound chambers were collected, and their content was analyzed for dry weight, total proteins, collagen, DNA, elastin, glycosaminoglycans, and specific mRNAs for collagens and TGF beta. In the GHK-Cu-injected wound chambers, a concentration-dependent increase of dry weight, DNA, total protein, collagen, and glycosaminoglycan contents was found. The stimulation of collagen synthesis was twice that of noncollagen proteins. Type I and type III collagen mRNAs were increased but not TGF beta mRNAs. An increase of the relative amount of dermatan sulfate was also found. A control tripeptide, L-glutamyl-L-histidyl-L-proline, had no significant effect. These results demonstrate that GHK-Cu is able to increase extracellular matrix accumulation in wounds in vivo. PMID:8227353

Recent in vitro data showed that it possesses several properties of a potential activator of wound repair. We investigated the effects of GHK-Cu in vivo, using the wound chamber model described previously (Schilling, J.A., W. Joel, and M.T. Shurley, 1959. Surgery [St. Louis]. 46:702-710). Stainless steel wire mesh cylinders were implanted subcutaneously on the back of rats. The animals were divided into groups that received sequential injections into the wound chamber of either saline (control group) or various concentrations of GHK-Cu. At the end of the experiments, rats were killed, wound chambers were collected, and their content was analyzed for dry weight, total proteins, collagen, DNA, elastin, glycosaminoglycans, and specific mRNAs for collagens and TGF beta. In the GHK-Cu-injected wound chambers, a concentration-dependent increase of dry weight, DNA, total protein, collagen, and glycosaminoglycan contents was found. The stimulation of collagen synthesis was twice that of noncollagen proteins. Type I and type III collagen mRNAs were increased but not TGF beta mRNAs. An increase of the relative amount of dermatan sulfate was also found. A control tripeptide, L-glutamyl-L-histidyl-L-proline, had no significant effect. These results demonstrate that GHK-Cu is able to increase extracellular matrix accumulation in wounds in vivo. Images PMID:8227353

    Dating the crucifixion on friday 3 April 33, when, at sunset a partially eclipsed Moon rised allows to interprete the speech of Saint Peter (Acts 2:20=Joel 3:4) on the day of Pentecost as including an account of this eclipse, as fulfillment of the Scriptures. Few minutes later the apparition of a third star of medium magnitude stated the beginning of the sabbatical rest: before that time Jesus has been buried, wrapped into the shroud. The observations of the equinoctial moonrise from the Mount of Olives on September 2013 are strongly in favour of the hypotehsis of possible observation of the lunar eclipse of 33 AD by Jewish people, as well as the sunrises observed from the Temple Institute terrace in Southern-East Jerusalem demonstrated that this eclipse could have been seen from Jerusalem. The depression of the horizon and the refraction allow to see Sun and Moon more than 1 degree below the geometrical horizon in the azimuthal direction ranging from 90 to 116, prologing to 16 minutes the duration of the partial lunar eclipse observed in 33AD. Texts of Matthew, Mark and Cyrillus of Jerusalem are also commented.

    This document describes the results of consensus agreements reached by the DARHT Safety Planning Team during the development of the update of the DARHT Safety Analysis Document (SAD). The SAD is one of the Authorization Basis (AB) Documents required by the Department prior to granting approval to operate the DARHT Facility. The DARHT Safety Planning Team is lead by Mr. Joel A. Baca of the Department of Energy Albuquerque Operations Office (DOE/AL). Team membership is drawn from the Department of Energy Albuquerque Operations Office, the Department of Energy Los Alamos Area Office (DOE/LAAO), and several divisions of the Los Alamos National Laboratory. Revision 1 of the DARHT SAD had been written as part of the process for gaining approval to operate the Phase 1 (First Axis) Accelerator. Early in the planning stage for the required update of the SAD for the approval to operate both Phase 1 and Phase 2 (First Axis and Second Axis) DARHT Accelerator, it was discovered that a conflict existed between the Laboratory approach to describing the management of facility and worker safety.

    The purpose of the study is to evaluate the effect of various laser techniques for bleaching teeth in office vital whitening. Hydrogen peroxide (30% concentration) and carbamide peroxide (10% solution) were used for chemical activation of bleaching process. Extracted non-carcious upper central incisors were exposed to laser radiation. Four different laser systems (Nd:YAG laser SHG, wavelength 0.53 μm, CTE:YAG laser, wavelength 2.7 μm, Nd:YAG laser, wavelength 1.06 μm, and alexandrite laser, wavelength 0.75 μm) were applied to accelerate the speed of the process. The end of chemical exposition was verified by the change of bleaching agent color. The color change was determined by stereomicroscope (Nikon SMZ 2T, Japan), the quality of surface structure was checked by scanning electron microscope Joel, Japan). The speed of bleaching rnaged from 630 s (chemical methods only) to 250-340 s (chemicals + alexandrite laser radiation). The Alexandrite laser application was considered an elective process to decrease the time of bleaching without modifying the surface.

  8. Early life history: A computer analysis

    NASA Astrophysics Data System (ADS)

    Bell, Peter M.

    Theoretical computer calculations, based in part on measurements of ‘young’ stars obtained with an orbiting telescope, may require a reexamination of some of the basic ideas about the composition of the earth's early atmosphere and the origin of life. According to Joel S. Levine, atmospheric geophysicist at the Langley Research Center, ‘the overwhelming majority of chemical evolution experiments since the first in 1952 may have been conducted with the wrong atmospheric mixture.’Astronomical measurements indicate that considerably more ultraviolet (UV) radiation may have been emitted by the young sun in comparison to that emitted by the present sun. Therefore, high levels of such radiation from the young sun, potentially harmful to life, would have been striking the earth at the very time life was being formed.Recent photochemical calculations by Levine and others at Langley state that at the time complex organic molecules (the precursors of living systems) were first formed from atmospheric gases the earth's atmosphere was not composed primarily of methane, ammonia, and hydrogen, as was previously supposed; instead, it was composed of carbon dioxide, nitrogen, and water vapor, all resulting from volcanic activity. The calculations indicate that both methane and ammonia were extremely short-lived and that such an atmosphere was photochemically unstable if it existed at all.

    Background. Morphological characterization of hemodialysis membranes is necessary to improve pore design. Aim. To delineate membrane pore structure of a high flux filter, Polyflux 210H. Methods. We used a Joel JSM-6010LV scanning electron microscope (SEM) and a SU6600 Hitachi field emission scanning electron microscope (FESEM) to characterize the pore and fiber morphology. The maximal diameters of selected uremic toxins were calculated using the macromolecular modeling Crystallographic Object-Oriented Toolkit (COOT) software. Results. The mean pore densities on the outermost and innermost surfaces of the membrane were 36.81% and 5.45%, respectively. The membrane exhibited a tortuous structure with poor connection between the inner and outer pores. The aperture's width in the inner surface ranged between 34 and 45 nm, which is 8.76–11.60 times larger than the estimated maximum diameter of β2-microglobulin (3.88 nm). Conclusion. The results suggest that the diameter size of inner pore apertures is not a limiting factor to middle molecules clearance, the extremely diminished density is. Increasing inner pore density and improving channel structure are strategies to improve clearance of middle molecules. PMID:23209902

  10. The child's right to an open future: is the principle applicable to non-therapeutic circumcision?

    PubMed

    Darby, Robert J L

    2013-07-01

    The principle of the child's right to an open future was first proposed by the legal philosopher Joel Feinberg and developed further by bioethicist Dena Davis. The principle holds that children possess a unique class of rights called rights in trust-rights that they cannot yet exercise, but which they will be able to exercise when they reach maturity. Parents should not, therefore, take actions that permanently foreclose on or pre-empt the future options of their children, but leave them the greatest possible scope for exercising personal life choices in adulthood. Davis particularly applies the principle to genetic counselling, arguing that parents should not take deliberate steps to create physically abnormal children, and to religion, arguing that while parents are entitled to bring their children up in accordance with their own values, they are not entitled to inflict physical or mental harm, neither by omission nor commission. In this paper, I aim to elucidate the open future principle, and consider whether it is applicable to non-therapeutic circumcision of boys, whether performed for cultural/religious or for prophylactic/health reasons. I argue that the principle is highly applicable to non-therapeutic circumcision, and conclude that non-therapeutic circumcision would be a violation of the child's right to an open future, and thus objectionable from both an ethical and a human rights perspective.

    Acid rain, climate change, air pollution, and the possible inadvertent depletion of ozone in the upper atmosphere will be among the subjects covered in an eight-part television series that premiers April 3, 1986, on public television. Part of a 32-lecture program entitled “Earth Science for Teachers,” this series will feature new developments in the physics, chemistry, and dynamics of the atmosphere and will focus on the role of anthropogenic activities that affect atmospheric composition and climate.Public television station WHRO-TV in Norfolk, Va., in cooperation with Virginia's Department of Education in Richmond, produced the series, which involved guest lecturers from across the country. Joel S. Levine, senior research scientist in the Atmospheric Science Division at the Langley Research Center of the National Aeronautics and Space Administration (NASA) in Hampton, Va., served as the organizer and coordinator of the series. Joseph D. Exline, Associate Director for Science, Virginia Department of Education, assisted with the development and production of the series.

    Joel Cohen proposed that "mathematics is biology's next microscope, only better; biology is mathematics' next physics, only better." Here, we aim for something even better. We try to combine mathematical physics and biology into a picoscope of life. For this, we merge techniques that were introduced and developed in modern mathematical physics, largely by Ludvig Faddeev, to describe objects such as solitons and Higgs and to explain phenomena such as anomalies in gauge fields. We propose a synthesis that can help to resolve the protein folding problem, one of the most important conundrums in all of science. We apply the concept of gauge invariance to scrutinize the extrinsic geometry of strings in three-dimensional space. We evoke general principles of symmetry in combination with Wilsonian universality and derive an essentially unique Landau-Ginzburg energy that describes the dynamics of a generic stringlike configuration in the far infrared. We observe that the energy supports topological solitons that relate to an anomaly similarly to how a string is framed around its inflection points. We explain how the solitons operate as modular building blocks from which folded proteins are composed. We describe crystallographic protein structures by multisolitons with experimental precision and investigate the nonequilibrium dynamics of proteins under temperature variations. We simulate the folding process of a protein at in vivo speed and with close to picoscale accuracy using a standard laptop computer. With picobiology as next pursuit of mathematical physics, things can only get better.

  13. Spectroscopic Observations of Nearby Low Mass Stars

    Young low-mass stars are known to be bright in X-ray and UV due to a high level of magnetic activity. By cross-correlating the GALEX Catalog with the WISE and 2MASS Point Source Catalogs, we have identified more than 2,000 stars whose UV excesses suggest ages in the 10-100 Myr range. We used the Shane 3-m telescope at Lick Observatory on Mount Hamilton, California to observe some of these 2,000 stars spectroscopically. We measured the equivalent width of lithium at 6708 A absorption and H-alpha emission lines. Out of a total of 122 stars observed with the Kast grating spectrometer, we find that roughly 10% have strong lithium absorption features. The high percentage of stars with lithium present is further evidence of the importance of UV emission as a youth indicator for low-mass stars. In addition, we used high-resolution spectra obtained with the Hamilton echelle spectrograph to determine radial velocities for several UV-bright stars. These radial velocities will be useful for the calculation of Galactic UVW space velocities for determination of possible moving group membership. This work is supported by NASA Astrophysics Data Analysis Program award NNX12AH37G to RIT and UCLA and Chilean FONDECYT grant 3130520 to Universidad de Chile.

  14. Emmanuel Levinas and the face of Terri Schiavo: bioethical and phenomenological reflections on a private tragedy and public spectacle.

    2012-12-01

    The controversial case of Terri Schiavo came to a close on March 31, 2005, with her death following the removal of a percutaneous endoscopic gastrostomy tube. This event followed years of controversy and social upheaval. Voices from across the entire political and cultural spectrums filled the airwaves and op-ed pages of major newspapers. Protests ensued outside of Ms. Schiavo's care facility. Ms. Schiavo's parents published videos of their daughter on the internet in an effort to prove that she was not in a vegetative state and could potentially recover. There is a certain mystery to the entire controversy given the fact that, legally, it was largely a matter of settled law. Precedent cases and legal statutes clearly set out the proper procedures and decisions to be followed in this case. Nonetheless, powerful challenges and virulent opposition to these standards arose. Through an investigation of this case as well as a comparative study of the case of Dax Cowart (in particular, the documentary depictions of Dax Cowart's case) and of a photograph by Joel-Peter Witkin, I plan to investigate the source of these social upheavals and hypothesize that they were largely the result of a phenomenological reaction to the human face.

    This project funded the participation of scientists from seven research groups, running more than thirty instruments, in the Winter Intensive Operating Period (January-February 2012) of the Clean Air for London (ClearfLo) campaign at a rural site in Detling, UK, 45 km southeast of central London. The primary science questions for the ClearfLo Winter IOP were, 1) what is the urban increment of particulate matter (PM) and other pollutants in the greater London area, and, 2) what is the contribution of solid fuel use for home heating to wintertime PM? An additional motivation for the Detling measurements was the question of whether coatings on black carbon particles enhance absorption. The following four key accomplishments have been identified so far: 1) Chemical, physical and optical characterization of PM from local and regional sources (Figures 2, 4, 5 and 6). 2) Measurement of urban increment in particulate matter and gases in London (Figure 3). 3) Measurement of optical properties and chemical composition of coatings on black carbon containing particles indicates absorption enhancement. 4) First deployment of chemical ionization instrument (MOVI-CI-TOFMS) to measure both particle-phase and gas-phase organic acids. (See final report from Joel Thornton, University of Washington, for details.) Analysis of the large dataset acquired in Detling is ongoing and will yield further key accomplishments. These measurements of urban and rural aerosol properties will contribute to improved modeling of regional aerosol emissions, and of atmospheric aging and removal. The measurement of absorption enhancement by coatings on black carbon will contribute to improved modeling of the direct radiative properties of PM.

  16. Modeling and detecting gravitational waves from compact stellar objects

    NASA Astrophysics Data System (ADS)

    Vallisneri, Michele

    In the next few years, the first detections of gravity- wave signals using Earth-based interferometric detectors will begin to provide precious new information about the structure, dynamics, and evolution of compact bodies, such as neutron stars and black holes, both isolated and in binary systems. The intrinsic weakness of gravity-wave signals requires a proactive approach to modeling the prospective sources and anticipating the shape of the signals that we seek to detect. Full-blown 3-D numerical simulations of the sources are playing and will play an important role in planning the gravity-wave data-analysis effort. This thesis explores the interplay between numerical source modeling and data analysis, looking closely at three case studies. (1)I evaluate the prospects for extracting equation-of-state information from neutron-star tidal disruption in neutron-star-black- hole binaries with LIGO-II, and I estimate that the observation of disrupting systems at distances that yield about one event per year should allow the determination of the neutron-star radius to about 15%, which compares favorably to the currently available electromagnetic determinations. (2)In collaboration with Lee Lindblom and Joel Tohline, I perform numerical simulations of the nonlinear dynamics of the r-mode instability in young, rapidly spinning neutron stars, and I find evidence that nonlinear couplings to other modes will not pose a significant limitation to the growth of the r-mode amplitude. (3)In collaboration with Alessandra Buonanno and Yanbei Chen, I study the problem of detecting gravity waves from solar-mass black-hole - black-hole binaries with LIGO-I, and I construct two families of detection templates that address the inadequacy of standard post-Newtonian theory to predict reliable waveforms for these systems.

    To prepare for the exploration of Mars by humans, as outlined in the new national vision for Space Exploration (VSE), the Mars Exploration Program Analysis Group (MEPAG), chartered by NASA's Mars Exploration Program (MEP), formed a Human Exploration of Mars Science Analysis Group (HEM-SAG), in March 2007. HEM-SAG was chartered to develop the scientific goals and objectives for the human exploration of Mars based on the Mars Scientific Goals, Objectives, Investigations, and Priorities.1 The HEM-SAG is one of several humans to Mars scientific, engineering and mission architecture studies chartered in 2007 to support NASA s plans for the human exploration of Mars. The HEM-SAG is composed of about 30 Mars scientists representing the disciplines of Mars biology, climate/atmosphere, geology and geophysics from the U.S., Canada, England, France, Italy and Spain. MEPAG selected Drs. James B. Garvin (NASA Goddard Space Flight Center) and Joel S. Levine (NASA Langley Research Center) to serve as HEMSAG co-chairs. The HEM-SAG team conducted 20 telecons and convened three face-to-face meetings from March through October 2007. The management of MEP and MEPAG were briefed on the HEM-SAG interim findings in May. The HEM-SAG final report was presented on-line to the full MEPAG membership and was presented at the MEPAG meeting on February 20-21, 2008. This presentation will outline the HEM-SAG biology and climate/atmosphere goals and objectives. A companion paper will outline the HEM-SAG geology and geophysics goals and objectives.

    The AAS celebrated its "semi-centennial" fifty-two years ago! It was actually the fiftieth anniversary of the "First Conference" of astronomers and astrophysicists held at the dedication of Yerkes Observatory in 1897, which led to the actual formation of the Society two years later. Otto Struve, president of the AAS, was publicizing the fiftieth anniversary of his Yerkes Observatory in 1947, and he simply announced it was also the semi-centennial of the Society. Joel Stebbins, the grand old man of the AAS who had joined it as a graduate student in 1900, and held nearly every office in the Society from councilor to president, supported Struve's early celebration of the anniversary, probably largely because he was to retire himself in 1948. The meeting was held at Northwestern University and at Yerkes. There were then 625 AAS members. About 140 of them attended the meeting, and presented some 50 papers, all oral, with no parallel sessions. Struve organized a symposium on stellar atmospheres, with 5 invited speakers, and the great majority of the contributed papers were also on stars, a few on nebulae and interstellar matter, one on galaxies, and none on cosmology. Not to be outdone, Gerard P. Kuiper, who had recently succeeded Struve as director of Yerkes Observatory, organized a second symposium on the atmospheres of the planets, held at Yerkes immediately after the AAS meeting. After two days of sessions at Evanston, the members had driven to Williams Bay for the closing session Saturday, at which Struve and Stebbins gave their versions of the history of the observatory and of the Society. The two symposia formed the bases for two important books, Astrophysics: A Topical Symposium, and The Atmospheres of the Earth and the Planets, edited by J. Allen Hynek and Kuiper respectively.

    1996-05-01

    George C. Comstock, the third director of Washburn Observatory, had a long and interesting career at Wisconsin. Born in Madison, he did his undergraduate work at Michigan under James Watson. From him Comstock learned the classical astronomy of stellar positions and celestial mechanics. He had one year of graduate work at Michigan before going to Madison as Watson's assistant in 1880, and remained after the latter's death as E.S. Holden's assistant. At Wisconsin, Comstock also studied law at the UW Law School in his ``spare time", to have an alternate career path. He was admitted to the bar in 1883 but never practiced. From 1885-7 he was on the Ohio State faculty with a summer working at Lick Observatory; then in 1887 became associate director back at Washburn Observatory. Two years later he succeeded to the full directorship, and kept the post until he retired in 1922 at the age of 67. All Comstock's research was in positional astronomy, and he considered his most important work to be the measurement of stellar aberration and atmospheric refraction. He also measured double stars with the 15-inch Washburn refractor. His main duty at UW was teaching, mostly ``practical astronomy" for civil engineering students. Comstock wrote several text books on astronomy, surveying, and least squares. He was the first head of the UW Graduate School, set up by President Charles R. Van Hise in 1904. Comstock was a highly effective administrator, and did much to build up research at UW. His own most successful students were Sidney D. Townley, Joel Stebbins, and Sebastian Albrecht. Because of his legal training, Comstock was involved as an officer in many scientific societies. He was one of the organizers of the AAS, its first secretary, and later its vice president, then president. He retired in 1922, and was succeeded by Stebbins, whom he helped to bring back to Madison from Illinois. After his retirement, Comstock lived in Beloit until his death in 1934.

    Motivation: Underrepresentation of racial groups represents an important challenge and major gap in phenomics research. Most of the current human phenomics research is based primarily on European populations; hence it is an important challenge to expand it to consider other population groups. One approach is to utilize data from EMR databases that contain patient data from diverse demographics and ancestries. The implications of this racial underrepresentation of data can be profound regarding effects on the healthcare delivery and actionability. To the best of our knowledge, our work is the first attempt to perform comparative, population-scale analyses of disease networks across three different populations, namely Caucasian (EA), African American (AA) and Hispanic/Latino (HL). Results: We compared susceptibility profiles and temporal connectivity patterns for 1988 diseases and 37 282 disease pairs represented in a clinical population of 1 025 573 patients. Accordingly, we revealed appreciable differences in disease susceptibility, temporal patterns, network structure and underlying disease connections between EA, AA and HL populations. We found 2158 significantly comorbid diseases for the EA cohort, 3265 for AA and 672 for HL. We further outlined key disease pair associations unique to each population as well as categorical enrichments of these pairs. Finally, we identified 51 key ‘hub’ diseases that are the focal points in the race-centric networks and of particular clinical importance. Incorporating race-specific disease comorbidity patterns will produce a more accurate and complete picture of the disease landscape overall and could support more precise understanding of disease relationships and patient management towards improved clinical outcomes.

    The National Institute on Alcohol Abuse and Alcoholism (NIAAA) sponsored a May 2002 workshop on gene-environment interaction (G x E) research to identify potential roadblocks to further research and to propose solutions to those roadblocks, to optimize investigative opportunities and multidisciplinary or multi-institution collaborations, and to explore ways that NIAAA can facilitate G x E studies. Sessions included panels on animal models; phenotypes; genetic findings in humans; study designs and analytical methods; and assessment of environmental risk. Key among the identified challenges to progress in G x E research were issues of study design and sampling strategies; logistic and methodological costs and constraints; availability and understanding of data analysis techniques; potential stigmatization of study populations; and organizational/bureaucratic structures that are inadequate to address the unique needs of large-scale, multicenter, longitudinal projects. Participants proposed a series of recommendations to address these issues. Session coordinators included: Gayle Boyd, Kendall Bryant, Page Chiapella, Vivian Faden, David Goldman, and Antonio Noronha. Session participants included: Laura Almasy, Henri Begleiter, Raul Caetano, Bruce Dudek, Mary Dufour, Cindy Ehlers, Mary-Anne Enoch, Joel Gelernter, David Goldman, Bridget Grant, Lorraine Gunzerath, Deborah Hasin, Andrew Heath, Victor Hesselbrock, J.

    Reviews the books, Cold War Social Science: Knowledge Production, Liberal Democracy, and Human Nature by Mark Solovey and Hamilton Cravens (2012) and Working Knowledge: Making the Human Sciences From Parsons to Kuhn by Joel Isaac (see record 2012-13212-000). Taken together, these two important books make intriguing statements about the way to write the histories of fields like psychology, sociology, anthropology, and economics in the Anglo American world during the 20th century. To date, histories of these fields have drawn on a number of fairly well-established punctuation marks to assist in periodization: the shift from interwar institutionalism in economics to postwar neoclassicism, with its physics-like emphasis on mathematical theory-building; the transition from the regnant prewar behaviorism through a postwar "cognitive revolution" in American psychology; and the move in fields like sociology and anthropology away from positivism and the pursuit of what has sometimes been called "grand theory" in the early postwar era toward a period defined by intellectual and political fragmentation, the reemergence of interpretive approaches and a reaction to the scientistic pretensions of the earlier period. These books, by contrast, provide perspectives orthogonal to such existing narrative frameworks by adopting cross-cutting lenses like the "Cold War" and the working practices of researchers in the social and behavioral sciences. As a result, they do much to indicate the value of casting a historiographical net beyond individual disciplines, or even beyond the "social sciences" or the "human sciences" sensu stricto, in the search for deeper patterns of historical development in these fields.

    Here we present the results of the 6th biennial optical interferometry imaging beauty contest. Taking advantage of a unique opportunity, the red supergiant VY CMa and the Mira variable R Car were observed in the astronomical H-band with three 4-telescope configurations of the VLTI-AT array using the PIONIER instrument. The community was invited to participate in the subsequent image reconstruction and interpretation phases of the project. Ten groups submitted entries to the beauty contest, and we found reasonable consistency between images obtained from independent workers using quite different algorithms. We also found that significant differences existed between the submitted images, much greater than in past beauty contests that were all based on simulated data. A novel crowd-sourcing" method allowed consensus median images to be constructed, filtering likely artifacts and retaining real features." We definitively detect strong spots on the surfaces of both stars as well as distinct circumstellar shells of emission (likely water/CO) around R Car. In a close contest, Joel Sanchez (IAA-CSIC/Spain) was named the winner of the 2014 interferometric imaging beauty contest. This process has shown that new comers" can use publicly-available imaging software to interpret VLTI/PIONIER imaging data, as long as sufficient observations are taken to have complete uv coverage { a luxury that is often missing. We urge proposers to request adequate observing nights to collect sufficient data for imaging and for time allocation committees to recognise the importance of uv coverage for reliable interpretation of interferometric data. We believe that the result of the proposed broad international project will contribute to inspiring trust in the image reconstruction processes in optical interferometry.

    The tenth meeting of the Astronomical and Astrophysical Society of America (later to become the AAS), held in August 1909, was also its tenth-anniversary (or decennial) meeting. Fifty-three members were present, as contrasted with the 1400 expected for the 194th, Centennial meeting to be held in Chicago in May-June 1999, and forty-one papers were presented, rather than the 1000 predicted for next year. Other similarities and differences between meetings then and now will be described and illustrated. Simon Newcomb, the first AAS President, had died in July 1909, and Edward C. Pickering, who had succeeded him in 1905 and was to remain President until 1919, eulogized him at the Yerkes meeting. Two Committees, on Luminous Meteors and on Comets, respectively, presented their reports, the latter's dealing mostly with plans for Comet Halley at its 1910 apparition. A high-level Special Committee issued a statement decrying a newspaper furor over establishing communication with Mars, which they said was then ``outside the range of contemporary science." Six of the members present at the 1909 meeting were women. Joel Stebbins, later to be Councilor, Secretary, Vice President and President, presented his first AAS paper, on his new selenium (photo-resistive) photometry. Frank Schlesinger, another future Society President, was also present and read an instrument-design paper. Ten of the papers were given by Yerkes and University of Chicago astronomers, including three by E. E. Barnard and two by Kurt Laves. Another six papers from distant Lick Observatory members were read in absentia. S. W. Burnham, who was at the Yerkes meeting, was the one famous astronomer who never joined the Society. Finally, the Council authorized publication of a Decennial Book, to provide a record of the first ten years of the young Society.

  8. Complex Protein Structures by Neutron Scattering

    Neutron scattering by an atom, unlike X-ray scattering, does not depend on the atomic number of that atom. Deuterium atoms scatter neutrons to the same extent as carbon or oxygen atoms and give positive peaks in a nuclear density map, while its isotope, hydrogen, gives a negative peak. Therefore neutron diffraction provides two results that are difficult to obtain from macromolecular X-ray diffraction studies: (1) the locations of hydrogen atoms, including the more mobile ones, and (2) the extent to which a hydrogen atom can be replaced by deuterium. The method shows whether an amino acid side chain (at a given pH value) is ionized or not. For example, one can ascertain whether histidine residues are singly or doubly protonated at the pH of study. Neutron diffraction studies can also be used to determine the absolute configuration of the course of a biochemical reaction by anomalous scattering and enzymatic deuteration of the substrate. Neutron diffraction experiments, however, require large crystals and these are often impossible to obtain for many macromolecules. Examples of reports of the use of neutron diffraction to provide information on enzymatic mechanism will be presented. This includes descriptions of our work on the enzyme D-xylose isomerase for which the orientation of a metal ion-bound water molecule in the active site was found. This water, thought to be involved in the isomerization step, was shown to be water (rather than hydroxyl) at pH 8.0. This analysis also revealed that one lysine has two rather than three attached hydrogen atoms and therefore lacks a positive charge. High-resolution X-ray studies (at 0.94 å) indicate how some side chains might move during catalysis. This combination of neutron and X-ray diffraction can contribute greatly to the elucidation of enzyme mechanisms. I thank Amy Katz, Xinmin Li, H. L. Carrell, Leighton Coates, Leif Hanson, Joel Harp, Paul Langan, and Benno Schoenborn who were involved in many of the described

    We analyze both long and short high resolution ultraviolet spectrum of Beta Lyrae eclipsing binary system observed with the International Ultraviolet Explorer (IUE) between 1980 and 1989. The main spectral features are P Cygni profiles originating from different environments of Beta Lyrae. A set of 23 Mg II k&h spectral lines at 2800 Å, originating from the extended envelope [Hack, M., 1980. IAUS, 88, 271H], have been identified and measured to determine their fluxes and widths. We found that there is spectral variability for these physical parameters with phase, similar to that found for the light curve [Kondo, Y., McCluskey, G.E., Jeffery, M.M.S., Ronald, S.P., Carolina, P.S. McCluskey, Joel, A.E., 1994. ApJ, 421, 787], which we attribute to the eclipse effects [Ak, H., Chadima, P., Harmanec, P., Demircan, O., Yang, S., Koubský, P., Škoda, P., Šlechta, M., Wolf, M., Božić, H., 2007. A&A, 463, 233], in addition to the changes of density and temperature of the region from which these lines are coming, as a result of the variability of mass loss from the primary star to the secondary [Hoffman, J.L., Nordsieck, K.H., Fox, G.K., 1998. AJ, 115, 1576; Linnell, A.P., Hubeny, I., Harmanec, P., 1998. ApJ, 509, 379]. Also we present a study of Fe II spectral line at 2600 Å, originating from the atmosphere of the primary star [Hack, M., 1980. IAUS, 88, 271H]. We found spectral variability of line fluxes and line widths with phase similar to that found for Mg II k&h lines. Finally we present a study of Si IV spectral line at 1394 Å, originating from the extended envelope [Hack, M., 1980. IAUS, 88, 271H]. A set of 52 Si IV spectral line at 1394 Å have been identified and measured to determine their fluxes and widths. Also we found spectral variability of these physical parameters with phase similar to that found for Mg II k&h and Fe II spectral lines.

  10. Potential disturbance interactions with a single IGV in an F109 turbofan engine

    NASA Astrophysics Data System (ADS)

    Kirk, Joel F.

    A common cause of aircraft engine failure is the high cycle fatigue of engine blades and stators. One of the primary causes of these failures is due to blade row interactions, which cause an aerodynamic excitation to be resonant with a mechanical natural frequency. Traditionally, the primary source of such aerodynamic excitations has been practically limited to viscous wakes from upstream components. However, more advanced designs require that blade rows be very highly loaded and closely spaced. This results in aerodynamic excitation from potential fields of down stream engine components, in addition to the known wake excitations. An experimental investigation of the potential field from the fan of a Honeywell F109 turbofan engine has been completed. The investigation included velocity measurements upstream of the fan, addition of an airfoil shaped probe upstream of the fan on which surface pressure measurements were acquired, and measurement of the velocity in the interaction region between the probe and the fan. This investigation sought to characterize the response on the upstream probe due to the fan potential field and the interaction between a viscous wake and the potential field; as such, all test conditions were for subsonic fan speeds. The results from the collected data show that fan-induced potential disturbances propagate upstream at acoustic velocities, to produce vane surface-pressure amplitudes as high as 40 percent Joel F. Kirk of the inlet, mean total pressure. Further, these fan-induced pressure amplitudes display large variations between the two vane surfaces. An argument is made that the structure of the pressure response is consistent with the presence of two distinct sources of unsteady forcing disturbances. The disturbances on the incoming-rotation-facing surface of the IGV propagated upstream at a different speed than those on the outgoing-rotation-facing surface, indicating that one originated from a rotating source and the other from a

    Like returns of Halley's comet the Olympic games occur periodically, though not as regularly in antiquity. Dates were also imprecise due to the chaotic calendars in use. Reported sightings of comets and eclipses can be used with game dates to help fix ancient events. However some reported darkening of the sun, e.g., after Julius Caesar's murder in 44 BC, was due to volcanic eruptions. A red comet, visible in daylight, first appeared during the games that year. It was also seen from China and Korea (Pang, Sciences 31, 30). Phlegon's ``Olympiads" (2nd century) says that Christ's crucifixion was in the 4th year of the 202nd Olympiad (AD 29-33), when a total solar eclipse occurred in the 6th hour. Only the Nov. 24, AD 29 eclipse over Asia Minor can match that, and Joel's prophecy (Acts 2, 14-21) that ``the sun will be turned to darkness and moon to blood." However it conflicts with ``the first day of Passover," as recorded by Mathew, Mark and Luke, i.e., full moon in early spring. Humphreys and Waddington (Nature 306, 743) have suggested meteorological darkening and the April 3, AD 33 lunar eclipse instead. Schaefer has questioned the eclipse's visibility from Jerusalem (31.46N, 35.14E). The six computations he cited gave dissimilar answers due to the imprecise rates of the secular lunar acceleration, and lengthening of the day used (Q.Jl.R.astr.Soc. 31, 53). Lunar laser ranging has since fixed the former at -26"/cen2. Analysis of ancient Chinese solar eclipse records, e.g., the April 21, 899 BC and April 4, AD 368 ``double dawns" over Zheng, has given us a delta T (in sec) = 30t2, where t is centuries before 1800 (Pang, Yau and Chou, in ``Dynamics of Ice Age Earth: A Modern Perspective," 1998). Our computations show that the moon rose over Jerusalem, with 1/3 still in the umbra and the rest in penumbra. Holdover meteorological darkening with long absorption air mass could have help reddened the moon also. Finally the first ``eclipse season" (the Aug. 21 lunar, and

    PREFACE The Nineteenth Workshop on Geothermal Reservoir Engineering was held at Stanford University on January 18-20, 1994. This workshop opened on a sad note because of the death of Prof. Henry J. Ramey, Jr. on November 19, 1993. Hank had been fighting leukemia for a long time and finally lost the battle. Many of the workshop participants were present for the celebration of his life on January 21 at Stanford's Memorial Church. Hank was one of the founders of the Stanford Geothermal Program and the Geothermal Reservoir Engineering Workshop. His energy, kindness, quick wit, and knowledge will long be missed at future workshops. Following the Preface we have included a copy of the Memorial Resolution passed by the Stanford University Senate. There were one hundred and four registered participants. Participants were from ten foreign countries: Costa Rica, England, Iceland, Italy, Japan, Kenya, Mexico, New Zealand, Philippines and Turkey. Workshop papers described the performance of fourteen geothermal fields outside the United States. Roland N. Home opened the meeting and welcomed the visitors to the campus. The key note speaker was J.E. ''Ted'' Mock who gave a presentation about the future of geothermal development. The banquet speaker was Jesus Rivera and he spoke about Energy Sources of Central American Countries. Forty two papers were presented at the Workshop. Technical papers were organized in twelve sessions concerning: sciences, injection, production, modeling, and adsorption. Session chairmen are an important part of the workshop and our thanks go to: John Counsil, Mark Walters, Dave Duchane, David Faulder, Gudmundur Bodvarsson, Jim Lovekin, Joel Renner, and Iraj Ershaghi. The Workshop was organized by the Stanford Geothermal Program faculty, staff, and graduate students. We wish to thank Pat Ota, Ted Sumida, and Terri A.

The diluted sample was analized in the ICP- MS, which was setted in high sensitivity mode. The results were compared through cross samples (the same samples tested in the laboratory were sent to another international laboratory, which works under accreditation ISO 17025 ) and no major deviations (5%) was obtained by making comparisons between the two laboratories. When comparing the results and evaluated the development of the art, it is concluded that this is an alternative that allows performing samples up to 50 alkaline fusions per day with great accuracy, saving resources and time.

    Joel Susskind, Gyula Molnar, and Lena Iredell NASA GSFC Sounder Research Team Abstract This paper compares spatial and temporal anomalies and trends of OLR as observed by CERES and computed based on AIRS retrieved surface and atmospheric geophysical parameters over the time period September 2002 - February 2010. This time period is marked by a substantial decreasing OLR trend on the order of -0.1 W/m2/yr averaged over the globe. There are very large spatial variations of these trends however, with local values ranging from -2.6 W/m2/yr to +3.0 W/m2/yr in the tropics. The spatial patterns of the AIRS and CERES trends are in essentially perfect agreement with each other, as are the anomaly time series averaged over different spatial regions. This essentially perfect agreement of OLR anomalies and trends derived from observations by two different instruments, in totally independent and different manners, implies that both sets of results must be highly accurate. The agreement of anomalies and trends of OLR as observed by CERES and computed from AIRS derived products also indirectly validates the anomalies and trends of the AIRS derived products as well. We used the anomalies and trends of AIRS derived water vapor and cloud products to explain why global OLR has had a large negative trend over the time period September 2002 through February 2010. Tropical OLR began to decrease significantly at the onset of a strong La Niña in mid-2007. AIRS products show that cloudiness and mid-tropospheric water vapor began to increase in the region 5°N - 20°S latitude extending eastward from 150°W - 30°E longitude at that time, with a corresponding very large drop in OLR in this region. Late 2009 is characterized by a strong El-Niño, with a corresponding change in sign of observed anomalies of mid-tropospheric water vapor, cloud cover, and OLR in this region, as well as that of OLR anomalies in the tropics and globally.

    Joel Franklin's textbook `Advanced Mechanics and General Relativity' comprises two partially overlapping, partially complementary introductory paths into general relativity at advanced undergraduate level. Path I starts with the Lagrangian and Hamiltonian formulations of Newtonian point particle motion, emphasising the action principle and the connection between symmetries and conservation laws. The concepts are then adapted to point particle motion in Minkowski space, introducing Lorentz transformations as symmetries of the action. There follows a focused development of tensor calculus, parallel transport and curvature, using examples from Newtonian mechanics and special relativity, culminating in the field equations of general relativity. The Schwarzschild solution is analysed, including a detailed discussion of the tidal forces on a radially infalling observer. Basics of gravitational radiation are examined, highlighting the similarities to and differences from electromagnetic radiation. The final topics in Path I are equatorial geodesics in Kerr and the motion of a relativistic string in Minkowski space. Path II starts by introducing scalar field theory on Minkowski space as a limit of point masses connected by springs, emphasising the action principle, conservation laws and the energy-momentum tensor. The action principle for electromagnetism is introduced, and the coupling of electromagnetism to a complex scalar field is developed in a detailed and pedagogical fashion. A free symmetric second-rank tensor field on Minkowski space is introduced, and the action principle of general relativity is recovered from coupling the second-rank tensor to its own energy-momentum tensor. Path II then merges with Path I and, supplanted with judicious early selections from Path I, can proceed to the Schwarzschild solution. The choice of material in each path is logical and focused. A notable example in Path I is that Lorentz transformations in Minkowki space are introduced

This research aims at achieving the limits of optimum spatial (and temporal) resolution for radar remote sensing by implementation of covariance informations concerned with error-balanced control as well as coherence of wave propagation effects through random composite media involved (based on Joel Franklin's approach of extended stochastic inversion). As a consequence the well-known inherent numerical instabilities of remote sensing are significantly reduced in a robust way by increasing the weight of main diagonal elements of the resulting composite matrix to be inverted with respect to off-diagonal elements following synergy relations as to the principle of correlation receiver in wireless telecommunications. It is shown that the enhancement of resolution for remote sensing holds for an integral and differential equation approach of inversion as well. In addition to that the paper presents a discussion on how the efficiency of inversion for radar data gets achieved by an overall optimization of inversion due to a novel neuro-genetic approach. Such kind of approach is in synergy with the priority research program "Organic Computing" of DFG / German Research Organization. This Neuro-Genetic Optimization (NGO) turns out, firstly, to take into account more detailed physical informations supporting further improved resolution such as the process of accretion for cometary nucleus, wave propagation effects from rough surfaces, ground clutter, nonlinear focusing, etc. as well as, secondly, to accelerate the computing process of inversion in a really significantly enhanced and fast way, e.g., enabling online-control of autonomous processes such as detection of unknown objects, navigation, etc. The paper describes in some detail how this neuro-genetic approach of optimization is incorporated into the

  4. Chandra Adds to Story of the Way We Were

    NASA Astrophysics Data System (ADS)

    2003-05-01

    Data from NASA's Chandra X-ray Observatory have enabled astronomers to use a new way to determine if a young star is surrounded by a planet-forming disk like our early Sun. These results suggest that disks around young stars can evolve rapidly to form planets, or they can be disrupted by close encounters with other stars. Chandra observed two young star systems, TW Hydrae and HD 98800, both of which are in the TW Hydrae Association, a loose cluster of 10 million-year-old stars. Observations at infrared and other wavelengths have shown that several stars in the TW Hydrae Association are surrounded by disks of dust and gas. At a distance of about 180 light years from Earth, these systems are among the nearest analogs to the early solar nebula from which Earth formed. "X-rays give us an excellent new way to probe the disks around stars," said Joel Kastner of the Rochester Institute of Technology in Rochester, NY during a press conference today in Nashville, Tenn. at a meeting of the American Astronomical Society. "They can tell us whether a disk is very near to its parent star and dumping matter onto it, or whether such activity has ceased to be important. In the latter case, presumably the disk has been assimilated into larger bodies - perhaps planets--or disrupted." TW Hydrae and HD 98800A Chandra 0th Order Image of HD98800 Kastner and his colleagues found examples of each type of behavior in their study. One star, TW Hydrae, namesake of the TW Hydrae Association, exhibited features in its X-ray spectrum that provide strong, new evidence that matter is accreting onto the star from a circumstellar disk. They concluded that matter is guided by the star's magnetic field onto one or more hot spots on the surface of the star. In contrast, Chandra observations of the young multiple star system HD 98800 revealed that its brightest star, HD 98800A, is producing X-rays much as the Sun does, from a hot upper atmosphere or corona. HD 98800 is a complex multiple-star system

  6. Chandra Discovers Elusive "Hot Bubble" in Planetary Nebula

    NASA Astrophysics Data System (ADS)

    2000-06-01

    NASA's Chandra X-ray Observatory has imaged for the first time a "hot bubble" of gas surrounding a dying, Sun-like star. This large region of very hot gas in the planetary nebula BD+30 3639 has a peculiar shape and contains elements produced in the core of the dying star. "The new Chandra image offers conclusive proof for the existence of the "hot bubble" that theorists have long predicted," said Professor Joel Kastner, of the Chester F. Carlson Center of Imaging Science at the Rochester Institute of Technology. Kastner leads a team of scientists who reported on this observation at the 196th national meeting of the American Astronomical Society in Rochester, New York. The Chandra image shows a region of 3 million degree Celsius gas that appears to fit inside the shell of ionized gas seen by the Hubble Space Telescope. The optical and X-ray emitting regions of BD+30 3639, which lies between 5000 and 8000 light years away, are roughly one million times the volume of our solar system. A planetary nebula (so called because it looks like a planet when viewed with a small telescope) is formed when a dying red giant star puffs off its outer layer, leaving behind a hot core that will eventually collapse to form a dense star called a white dwarf. According to theory, a "hot bubble" is formed when a new, two million mile per hour wind emanating from the hot core rams into the ejected atmosphere, producing energetic shocks and heating the interaction region to temperatures of millions of degrees. Previous X-ray observations hinted that X rays might be coming from a region larger than the central star but it remained for Chandra to provide definite proof. The shape of the X-ray emission was a surprise to the researchers. "This suggests that the red giant atmosphere was not ejected symmetrically,"said Kastner. "It might be pointing to an unseen companion star," The spectrum shows a large abundance of neon in the X-ray-emitting gas. This indicates that gas contained in the hot

    The astronomical community lost one of its most buoyant and caring individuals when Beth Brown died, unexpectedly, at the age of 39 from a pulmonary embolism. Beth Brown was born in Roanoke, Virginia where she developed a deep interest in astronomy, science, and science fiction (Star Trek). After graduating as the valedictorian of William Fleming High School's Class of 1987, she attended Howard University, where she graduated summa cum laude in 1991 with a bachelor's degree in astrophysics. Following a year in the graduate physics program at Howard, she entered the graduate program in the Department of Astronomy at the University of Michigan, the first African-American woman in the program. She received her PhD in 1998, working with X-ray observations of elliptical galaxies from the Röntgen Satellite (ROSAT; Joel Bregman was her advisor). She compiled and analyzed the first large complete sample of such galaxies with ROSAT and her papers in this area made an impact in the field. Following her PhD, Beth Brown held a National Academy of Science & National Research Council Postdoctoral Research Fellowship at NASA's Goddard Space Flight Center. Subsequently, she became a civil servant at the National Space Science Data Center at GSFC, where she was involved in data archival activities as well as education and outreach, a continuing passion in her life. In 2006, Brown became an Astrophysics Fellow at GSFC, during which time she worked as a visiting Assistant Professor at Howard University, where she taught and worked with students and faculty to improve the teaching observatory. At the time of her death, she was eagerly looking forward to a new position at GSFC as the Assistant Director for Science Communications and Higher Education. Beth Brown was a joyous individual who loved to work with people, especially in educating them about our remarkable field. Her warmth and openness was a great aid in making accessible explanations of otherwise daunting astrophysical

  8. Socorro Students Translate NRAO Web Pages Into Spanish

    2002-07-01

    Six Socorro High School students are spending their summer working at the National Radio Astronomy Observatory (NRAO) on a unique project that gives them experience in language translation, World Wide Web design, and technical communication. Under the project, called "Un puente a los cielos," the students are translating many of NRAO's Web pages on astronomy into Spanish. "These students are using their bilingual skills to help us make basic information about astronomy and radio telescopes available to the Spanish-speaking community," said Kristy Dyer, who works at NRAO as a National Science Foundation postdoctoral fellow and who developed the project and obtained funding for it from the National Aeronautics and Space Administration. The students are: Daniel Acosta, 16; Rossellys Amarante, 15; Sandra Cano, 16; Joel Gonzalez, 16; Angelica Hernandez, 16; and Cecilia Lopez, 16. The translation project, a joint effort of NRAO and the NM Tech physics department, also includes Zammaya Moreno, a teacher from Ecuador, Robyn Harrison, NRAO's education officer, and NRAO computer specialist Allan Poindexter. The students are translating NRAO Web pages aimed at the general public. These pages cover the basics of radio astronomy and frequently-asked questions about NRAO and the scientific research done with NRAO's telescopes. "Writing about science for non-technical audiences has to be done carefully. Scientific concepts must be presented in terms that are understandable to non-scientists but also that remain scientifically accurate," Dyer said. "When translating this type of writing from one language to another, we need to preserve both the understandability and the accuracy," she added. For that reason, Dyer recruited 14 Spanish-speaking astronomers from Argentina, Mexico and the U.S. to help verify the scientific accuracy of the Spanish translations. The astronomers will review the translations. The project is giving the students a broad range of experience. "They are

  9. Astronomers Find New Evidence for the Violent Demise of Sun-like Stars

    NASA Astrophysics Data System (ADS)

    2005-06-01

    Two astronomers have used NASA's Chandra X-ray Observatory to discover a shell of superheated gas around a dying star in the Milky Way galaxy. Joel Kastner, professor of imaging science at the Rochester Institute of Technology, and Rodolpho Montez, a graduate student in physics and astronomy at the University of Rochester, will present their results today at the American Astronomical Society meeting in Minneapolis. Their discovery shows how material ejected at two million miles per hour during the final, dying stages of sun-like stars can heat previously ejected gas to the point where it will emit X-rays. The study also offers new insight into how long the ejected gas around dying stars can persist in such a superheated state. According to Kastner, the hot gas shows up in high-resolution Chandra X-ray images of the planetary nebula NGC 40, which is located about 3,000 light years away from Earth in the direction of the constellation Cepheus. Chandra X-ray & NOAO Optical Composite of NGC 40 Chandra X-ray & NOAO Optical Composite of NGC 40 "Planetary nebulae are shells of gas ejected by dying stars," Kastner explains. "They offer astronomers a 'forecast' of what could happen to our own sun about five billion years from now - when it finally exhausts the reservoir of hydrogen gas at its core that presently provides its source of nuclear power." In his research, Montez discovered the X-ray emitting shell in NGC 40 by generating an image that uses only specific energy-selected X-rays - revealing a ring of superheated gas that lies just within the portions of the nebula that appear in optical and infrared images. "This hot bubble of gas vividly demonstrates how, as a planetary nebula forms, the gas ejection process of the central, dying star becomes increasingly energetic," Kastner notes. "Mass ejection during stellar death can result in violent collisions that can heat the ejected gas up to temperatures of more than a million degrees." The detection of X-rays from NGC

    The quest for the nature of dark matter has reached a historical point in time, with several different and complementary experiments on the verge of conclusively exploring large portions of the parameter space of the most theoretically compelling particle dark matter models. This focus issue on dark matter and particle physics brings together a broad selection of invited articles from the leading experimental and theoretical groups in the field. The leitmotif of the collection is the need for a multi-faceted search strategy that includes complementary experimental and theoretical techniques with the common goal of a sound understanding of the fundamental particle physical nature of dark matter. These include theoretical modelling, high-energy colliders and direct and indirect searches. We are confident that the works collected here present the state of the art of this rapidly changing field and will be of interest to both experts in the topic of dark matter as well as to those new to this exciting field.

Smog chamber experiments were then conducted in the PSI facilities to investigate the aging of biomass burning emissions. The analysis of samples collected during these experiments using the DART/Q-ToF approach, confirmed that nitrocatechols and methylated nitrocatechols originate from biomass burning processes. More importantly our results confirm that nitrocatechols and their methylated derivatives are quasi exclusively from secondary origin. Considering the abundance of biomass burning primary aerosol, and the large fraction of unexplained SOA, this result is of prime importance. Cody. R., Laramée J.

  12. X-Ray Outburst from Young Star in McNeil's Nebula

    NASA Astrophysics Data System (ADS)

    2004-07-01

    Observations with NASA's Chandra X-ray Observatory captured an X-ray outburst from a young star, revealing a probable scenario for the intermittent brightening of the recently discovered McNeil's Nebula. It appears the interaction between the young star's magnetic field and an orbiting disk of gas can cause dramatic, episodic increases in the light from the star and disk, illuminating the surrounding gas. "The story of McNeil's Nebula is a wonderful example of the importance of serendipity in science," said Joel Kastner of the Rochester Institute of Technology in Rochester, New York, lead author of a paper in the July 22 issue of Nature describing the X-ray results. "Visible-light images were made of this region several months before Jay McNeil made his discovery, so it could be determined approximately when and by how much the star flared up to produce McNeil's Nebula." The small nebula, which lies in the constellation Orion about 1300 light years from Earth, was discovered with a 3-inch telescope by McNeil, an amateur astronomer from Paducah, Kentucky, in January 2004. In November 2002, a team led by Ted Simon of the Institute for Astronomy in Hawaii had observed the star-rich region with Chandra in search of young, X-ray emitting stars, and had detected several objects. Optical and infrared astronomers had, as part of independent surveys, also observed the region about a year later, in 2003. After the announcement of McNeil's discovery, optical, infrared and X-ray astronomers rushed to observe the region again. They found that a young star buried in the nebula had flared up, and was illuminating the nebula. This star was coincident with one of the X-ray sources discovered earlier by Simon. Chandra observations obtained by Kastner's group just after the optical outburst showed that the source had brightened fifty-fold in X-rays when compared to Simon's earlier observation. The visible-light eruption provides evidence that the cause of the X-ray outburst is the

GEM constitutes greater than 99% of the mercury mass in most rural and remote locations. While dry and wet deposition of atmospheric mercury is thought to be dominated by oxidized mercury (a.k.a. reactive mercury), only small GEM uptake to environmental surfaces could impact the input of mercury to terrestrial and aquatic ecosystems. Dry deposition and subsequent re-emission of gaseous elemental mercury is a pathway from the atmosphere that remains only partially understood from a mechanistic perspective. In order to properly model GEM dry deposition and re-emission an understanding of its dependence on irradiance, temperature, and relative humidity must be measured and parameterized for a broad spectrum of environmental surfaces colocated with surrogate deposition surfaces used to make field based dry deposition measurements. Measurements of isotopically enriched GEM dry deposition were made with a variety of environmental surfaces in a controlled environment room at the University of Wisconsin Biotron. The experimental set up allowed dry deposition components which are not easily separated in the field to be decoupled. We were able to isolate surface transfer processes from variabilities caused by

    research communities have established collaborations between researchers in France and the UK, and both are concerned with the science and applications of ultrasound. Although there are some differences in scope, there is also very significant overlap, and much shared interest. Furthermore, the possibilities to extend contacts between the members in both countries, and between disciplines, was an additional benefit of a joint conference. The suggestion of a joint meeting was therefore met with enthusiasm from both sides. The conference was arranged as a single-stream series of presentations and discussions in the style of a workshop. Four leading authorities in their fields were invited to give 50-minute keynote addresses; these were Joel Gilbert (Université du Maine, France), Peter Wells (Cardiff University, UK), John Willis (Cambridge University, UK), and Philippe Destuynder (Conservatoire National des Arts et Métiers, France). Other participants gave 20-minute oral presentations or posters. There were 82 contributions in total. Participants were given the option to submit manuscripts to be peer-reviewed for publication in these proceedings. The cost of participation at the conference was part-supported by the GDR for all attendees. The conference was a great success, and it was widely acknowledged that it achieved all the hopes for communication, collaboration, and new contacts and opportunities. However, the attendees of the conference are also left with a very sad memory. This was the last working engagement of Andrew Temple, who died suddenly on 6 February 2010. Andrew was the Chairman of the PAG of the Institute of Physics and an enthusiast for both AFPAC and GDR activities. He was the central organiser of this conference, across all aspects, from his technical contributions as a member of the technical committee, to his provision of local information and plans for social activities and outings.

    This final report is presented by Langston University (LU) for the project entitled "Langston University High Energy Physics" (LUHEP) under the direction of principal investigator (PI) and project director Professor Joel Snow. The project encompassed high energy physics research performed at hadron colliders. The PI is a collaborator on the DZero experiment at Fermi National Accelerator Laboratory in Batavia, IL, USA and the ATLAS experiment at CERN in Geneva, Switzerland and was during the entire project period from April 1, 1999 until May 14, 2012. Both experiments seek to understand the fundamental constituents of the physical universe and the forces that govern their interactions. In 1999 as member of the Online Systems group for Run 2 the PI developed a cross-platform Python-based, Graphical User Interface (GUI) application for monitoring and control of EPICS based devices for control room use. This served as a model for other developers to enhance and build on for further monitoring and control tasks written in Python. Subsequently the PI created and developed a cross-platform C++ GUI utilizing a networked client-server paradigm and based on ROOT, the object oriented analysis framework from CERN. The GUI served as a user interface to the Examine tasks running in the D\\O\\ control room which monitored the status and integrity of data taking for Run 2. The PI developed the histogram server/control interface to the GUI client for the EXAMINE processes. The histogram server was built from the ROOT framework and was integrated into the D\\O\\ framework used for online monitoring programs and offline analysis. The PI developed the first implementation of displaying histograms dynamically generated by ROOT in a Web Browser. The PI's work resulted in several talks and papers at international conferences and workshops. The PI established computing software infrastructure at LU and U. Oklahoma (OU) to do analysis of DZero production data and produce simulation data

    Joel Franklin's textbook `Advanced Mechanics and General Relativity' comprises two partially overlapping, partially complementary introductory paths into general relativity at advanced undergraduate level. Path I starts with the Lagrangian and Hamiltonian formulations of Newtonian point particle motion, emphasising the action principle and the connection between symmetries and conservation laws. The concepts are then adapted to point particle motion in Minkowski space, introducing Lorentz transformations as symmetries of the action. There follows a focused development of tensor calculus, parallel transport and curvature, using examples from Newtonian mechanics and special relativity, culminating in the field equations of general relativity. The Schwarzschild solution is analysed, including a detailed discussion of the tidal forces on a radially infalling observer. Basics of gravitational radiation are examined, highlighting the similarities to and differences from electromagnetic radiation. The final topics in Path I are equatorial geodesics in Kerr and the motion of a relativistic string in Minkowski space. Path II starts by introducing scalar field theory on Minkowski space as a limit of point masses connected by springs, emphasising the action principle, conservation laws and the energy-momentum tensor. The action principle for electromagnetism is introduced, and the coupling of electromagnetism to a complex scalar field is developed in a detailed and pedagogical fashion. A free symmetric second-rank tensor field on Minkowski space is introduced, and the action principle of general relativity is recovered from coupling the second-rank tensor to its own energy-momentum tensor. Path II then merges with Path I and, supplanted with judicious early selections from Path I, can proceed to the Schwarzschild solution. The choice of material in each path is logical and focused. A notable example in Path I is that Lorentz transformations in Minkowki space are introduced

When he became emeritus, Maury was still very active both in research and in running the Erice School of Cosmic Ray Astrophysics (after 1982). He was interested in having a base of operations for the school. He approached me asking whether Maryland would be a possibility. I was delighted and suggested a Visiting professorship to be able to continue his work (without having to move out of the Washington, DC, area). Thus started Maury's association with Maryland which continued until his death. Maury was not only an outstanding scientist, but he was a true gentleman and a good friend. He was an ambassador for the field of Cosmic Rays. His friendly personality, always warm and kind to students and colleagues, was quite infectious. Maury contributed to both experimental and theoretical investigations of cosmic rays and their central role in connecting many diverse disciplines in particle physics, astrophysics, geophysics, acoustical physics. He was outstanding scientist and was greatly concerned about world peace and human affairs. Maury passed away on 27 February 2008, at the age of 92, in Alexandria, Virginia. Four years prior to his death he was still swimming in the Mediterranean during the Cosmic Ray School sessions at Erice. He is survived by his wife, Ruth Auslander, and children Joel N. Shapiro, Elana Ashley, Raquel T. Kislinger, Mark and Bonnie Auslander, Beth Kessler, Lionel Ames, and Naomi Mirvis and grand children.

    their type," said Norbert S. Schulz, MIT research scientist at the Chandra X-ray Center, who leads the Orion Project. "And by extreme, we mean temperatures which are in some cases well above 60 million degrees." The hottest massive star known so far has been around 25 million degrees. The great Orion Nebula harbors the Orion Nebula Cluster (ONC), a loose association of around 2,000 mostly very young stars of a wide range of mass confined within a radius of less than 10 light years. The Orion Trapezium Cluster is a younger subgroup of stars at the core of the ONC confined within a radius of about 1.5 light years. Its median age is around 300,000 years. The constant bright light of the Trapezium and its surrounding stars at the heart of the Orion nebula (M42) are visible to the naked eye on clear nights. In X-rays, these young stars are constantly active and changing in brightness, sometimes within half a day, sometimes over weeks. "Never before Chandra have we seen images of stellar activity with such brilliance," said Joel Kastner, professor at the Chester F. Carlson Center for Imaging Science at the Rochester Institute of Technology. "Here the combination of very high angular resolution, with high quality spectra that Chandra offers, clearly pays off." The observation was performed using the High Energy Transmission Grating Spectrometer (HETGS) and the X-ray spectra were recorded with the spectroscopic array of the Advanced CCD Imaging Spectrometer (ACIS). The ACIS detector is a sophisticated version of the CCD detectors commonly used in video cameras or digital cameras. The orion stars are so bright in X-rays that they easily saturate the ccds. Here the team used the gratings as a blocking filter. Orion Trapezium - X-ray & Optical JPEG, TIFF, PS X-ray contours of the Chandra observation overlaid onto the optical Hubble image (courtesy of J.

  5. Chandra Finds Evidence for Stellar Cannibalism

    NASA Astrophysics Data System (ADS)

    2010-09-01

    Evidence that a star has recently engulfed a companion star or a giant planet has been found using NASA's Chandra X-ray Observatory. The likely existence of such a "cannibal" star provides new insight into how stars and the planets around them may interact as they age. The star in question, known as BP Piscium (BP Psc), appears to be a more evolved version of our Sun, but with a dusty and gaseous disk surrounding it. A pair of jets several light years long blasting out of the system in opposite directions has also been seen in optical data. While the disk and jets are characteristics of a very young star, several clues -- including the new results from Chandra -- suggest that BP Psc is not what it originally appeared to be. Instead, astronomers have suggested that BP Psc is an old star in its so-called red giant phase. And, rather than being hallmarks of its youth, the disk and jets are, in fact, remnants of a recent and catastrophic interaction whereby a nearby star or giant planet was consumed by BP Psc. When stars like the Sun begin to run out of nuclear fuel, they expand and shed their outer layers. Our Sun, for example, is expected to swell so that it nearly reaches or possibly engulfs Earth, as it becomes a red giant star. "It appears that BP Psc represents a star-eat-star Universe, or maybe a star-eat-planet one," said Joel Kastner of the Rochester Institute of Technology, who led the Chandra study. "Either way, it just shows it's not always friendly out there." Several pieces of information have led astronomers to rethink how old BP Psc might be. First, BP Psc is not located near any star-forming cloud, and there are no other known young stars in its immediate vicinity. Secondly, in common with most elderly stars, its atmosphere contains only a small amount of lithium. Thirdly, its surface gravity appears to be too weak for a young star and instead matches up with one of an old red giant. Chandra adds to this story. Young, low-mass stars are brighter than

    Michael John Klein died on 14 May 2005 at home in South Pasadena, California. The cause of death was tongue cancer that metastasized to the lungs. He was a non-smoker. Mike was a passionate radio astronomer, a trusted astronomical observer, an educator and a family man. Mike was born on 19 January 1940 in Ames, Iowa, the son of Florence Marie (Graf) and Fred Michael Klein. His mother was a homemaker, and his father was a banker. Mike had two older sisters, Lois Jean (Klein) Flauher and Marilyn June (Klein) Griffin. In 1962, Mike married his high school sweetheart Barbara Dahlberg, who survives him along with their three children, Kristin Marie (Klein) Shields, Michael John Klein Jr., Timothy Joel Klein, and six grandchildren. Mike developed a love for astronomy early in his life, and credited an early morning, newspaper-delivery route that he had at age twelve, which took him outside well before sunrise. He told family members that as he walked along his route, he stared into the sky and wondered what everything was. He studied sky charts, located stars, and began to understand how the planets shifted their positions relative to the stars each day. Another big influence in Mike's life was his brother in-law, Jim Griffin. Jim helped Mike understand that his passion for science did not have to remain a hobby, but could and should become a career. Jim's encouragement led Mike to attend Iowa State University in Ames, where he earned a BS in electrical engineering in 1962. Mike then started graduate school in electrical engineering at Michigan State, but after one semester transferred to the University of Michigan, Ann Arbor, where he earned an MS (1966) and PhD (1968) in astronomy. His doctoral dissertation, under the direction of Professor Fred Haddock, was based on extensive observations of the planets and examined the physical and thermal properties of planetary atmospheres and surfaces. Mike was awarded a Resident Research Associate position at JPL by the National

"Observations of cosmic masers -- naturally-occurring microwave radio amplifiers -- will tell us new things about the process of star formation and activity in the heart of other galaxies." "By the 1980s, radio astronomers were observing the universe with assemblages of radio telescopes whose resolving power was limited only by the size of the Earth. Now, through a magnificent international effort, we will be able to break this barrier and see fine details of celestial objects that are beyond the reach of a purely ground-based telescope array. We anticipate a rich harvest of new scientific knowledge from VSOP," said Dr. Paul Vanden Bout, Director of NRAO. In the first weeks after launch, scientists and engineers will "test the deployment of the reflecting mesh telescope in orbit, the wide-band data link from the satellite to the ground, the performance of the low noise amplifiers in orbit, and the high-precision orbit determination and attitude control necessary for VLBI observations with an orbiting telescope," according to Dr. Joel Smith, manager of the U.S. Space VLBI project at JPL. Scientific observations are expected to begin in May. The 26-foot diameter orbiting radio telescope will observe celestial radio sources in concert with a number of the world's ground-based radio telescopes. The 1,830-pound satellite will be launched from ISAS' Kagoshima Space Center, at the southern tip of Kyushu, one of Japan's main islands, and will be the first launch with ISAS' new M-5 series rocket. The satellite will go into an elliptical orbit, varying between 620 to 12,400 miles above the Earth's surface. This orbit provides a wide range of distances between the satellite and ground-based telescopes, which is important for producing a high-quality image of the radio source being observed. One orbit of the Earth will take about six hours. The satellite's observations will concentrate on some of the most distant and intriguing objects in the

    tendency to prefer sugars and proteins that are one chirality only, but it is unknown whether this is a universal preference or a quirk of Earth-based life. Carroll and McGuires new detection in a star-forming cloud of material near the center of the Milky Way does not distinguish whether the propylene oxide is left- or right-handed, but it does show that the cosmos is capable of producing complex molecules that are essential to biology. In the future, they hope to use polarized light to directly measure chirality.Next, Joel Green from STScI presented how a young star surrounded by a bright protoplanetary disk, FU Orionis, has changed since a bright outburst in 1936. Since then, it has consumed some 80 Jupiters worth of material! By comparing observations of the disks brightness taken twelve years apart, Green showed that the hottest inner regions of the disk have faded significantly while the cooler regions farther out have not. In other words, the star has consumed the hot parts of the disk closest to it and altered the chemical composition in the disk that remains. This is likely what our own Sun experienced as a young star, and has implications for planet formation because the chemical composition of the disk affects what materials are available for forming planets. Green hopes that future observations with the Webb telescope will complement existing Spitzer and SOFIA data.A gluttonous star may hold clues to #planet formation: https://t.co/bTcFJM3xcY#aas228pic.twitter.com/nDWLF3bXVN NASA PlanetQuest (@PlanetQuest) June 14, 2016
