  2. The madness of Gerard de Nerval.

    PubMed

    Beveridge, Allan

    2014-06-01

    This paper examines the madness of Gerard de Nerval, the nineteenth-century French writer. It looks at his account of mental disturbance, how he responded to the psychiatric profession and how he reacted to being diagnosed as insane. It considers his autobiographical novella of madness, Aurelia, which he began at the suggestion of his alienist, Dr Emile Blanche, and while he was still an asylum inmate. Nerval's story raises important questions about the nature of madness. Is it, as he contended, a mystical experience revealing truths about spiritual worlds inaccessible to the 'sane'? Does psychiatry fail to understand it and inappropriately reduce it to the categories of scientific reason? Or are such notions of the spiritual value of madness guilty of the charge that they romanticise insanity? Do they make extravagant claims for an experience that is often disturbing and debilitating? What is the relationship between madness and recovery? Should an individual try to forget their experience of mental disturbance once they recover, or should they examine what the event reveals about themselves? Can the language of madness be decoded to unveil profound truths as Carl Jung and R.D. Laing have suggested, or is it, as the psychiatrist German Berrios maintains, merely a series of 'empty speech acts', signifying nothing? And finally, how does one avoid writing about madness, and instead write madness? PMID:24284501

  3. Gerard Kuiper and the Infrared Detector

    2013-10-01

    The life and contributions of Gerard Kuiper have been documented by Dale Cruikshank in his National Academy of Sciences biography. I will argue that particularly important in this eventful life was Kuiper's war time experiences. Kuiper's wartime role evolved as the war unfolded, but towards the end he was charged by the US military with reporting German progress with war-related technologies and the activities of scientists under Nazi control. He interviewed a great many scientists, including his own PhD mentor (Ejnar Hertzsprung), and when Kuiper was the only person available, he interviewed concentration-camp victims. He carried briefing sheets that identified the technologies being sought by the allies and the major fraction of these involved infrared equipment. He sent back to the USA boxes of documents, and large amounts of equipment, and he stressed to the military his interest in these for his own research. It seems very likely that in this way an effective PbS infrared detector, so critical to Kuiper's career and the future of planetary science, came to the USA and to Robert Cashman's laboratory at Northwestern University. As the war was winding down, Cashman and Kuiper worked together to develop a practical infrared spectrometer for astronomical use. Within months, Kuiper discovered the C02 atmospheres on Mars and Venus.

    The MATHEW/ADPIC models are employed in the first phase of a project to evaluate the environmental impact of proposed OTEC plants off the coast of Hawaii. The MATHEW/ADPIC models developed to assess regional plume transport in the atmospheric boundary layer are described. The code modifications of MATHEW/ADPIC required for the OTEC calculation are detailed. A number of test cases are examined. The calculations indicate that the MATHEW/ADPIC codes may be utilized to provide physically reasonable results for the hydrological problems considered.

    The three-dimensional diagnostic wind field model (MATHEW) and the particle-in-cell transport and diffusion model (ADPIC) are used by the Atmospheric Release Advisory Capability (ARAC) for real-time assessments of the consequences from accidental releases of radioactivity into the atmosphere. For the dispersion of hazardous heavier-than-air gases, a time-dependent, three-dimensional finite element model (FEM3) is used. These models have been evaluated extensively against a wide spectrum of field experiments involving the release of chemically inert tracers or heavier-than-air gases. The results reveal that the MATHEW/ADPIC models are capable of simulating the spatial and temporal distributions of tracer concentration to within a factor of 2 for 50% of the measured tracer concentrations for near surface releases in relatively flat terrain and within a factor of 2 for 20% of the comparisons for elevated releases in complex terrain. The FEM3 model produces quite satisfactory simulations of the spatial and temporal distributions of heavier-than-air gases, typically within a kilometer of the release point. The ARAC consists of a centralized computerized emergency response system that is capable of supporting up to 100 sites and providing real-time predictions of the consequence of transportation accidents that may occur anywhere. It utilizes pertinent accident information, local and regional meteorology, and terrain as input to the MATHEW/ADPIC models for the consequence analysis. It has responded to over 150 incidents and exercises over the past decade.

    We obtain series solutions, the discrete spectrum, and supersymmetric partners for a quantum double-oscillator system. Its potential features a superposition of the one-parameter Mathews-Lakshmanan interaction and a one-parameter harmonic or inverse harmonic oscillator contribution. Furthermore, our results are transferred to a generalized Pöschl-Teller model that is isospectral to the double-oscillator system.

    Dr. Alan Dale Fiala, astronomer and expert on solar eclipses, died on May 26, 2010 in Arlington, Virginia, of respiratory failure after a brief illness. He was 67. Fiala had been a staff astronomer at the U.S. Naval Observatory in Washington, D.C., for his entire professional career, where he rose from a position as a summer intern to become the Chief of the Nautical Almanac Office, responsible for annual publications for astronomy and navigation that are used the world over. He retired from the observatory in 2000. Although a childhood case of polio affected his mobility for the rest of his life, he seldom let his physical constraints limit his activities, which were many and varied. Alan Fiala was born in Beatrice, Nebraska on November 9, 1942, the middle son of Emil A. ("John") and Lora Marie Fiala. Fiala's father was a postal clerk and Civil Service examiner. Fiala expressed interest in astronomy at a very young age. He contracted polio when he was 9. He graduated from Beatrice High School in 1960 with a straight-A average and went on to study at Carleton College. He received his B.A. summa cum laude after three years, in 1963, with a major in astronomy and minors in physics and mathematics. He was elected to Phi Beta Kappa, Sigma Xi, and Pi Mu Epsilon (mathematics). In 1962, Alan Fiala obtained a job as a summer intern at the Naval Observatory in Washington, working in the Nautical Almanac Office (NAO). He entered the graduate program at Yale University and continued to work summers at the observatory. He received his Ph.D. in 1968, under Gerald Clemence. His dissertation was titled "Determination of the Mass of Jupiter from a Study of the Motion of 57 Mnemosyne." After receiving his doctorate, Fiala became a permanent member of the Naval Observatory staff.

    NASA researchers Gerard Schkolnik (left) and John Orme monitor equipment in the control room at the Dryden Flight Research Center, Edwards, California, during a flight of an F-15 Highly Integrated Digital Electronic Control (HIDEC) research aircraft. The system was developed on the F-15 to investigate and demonstrate methods of obtaining optimum aircraft performance. The major elements of HIDEC were a Digital Electronic Flight Control System (DEFCS), a Digital Electronic Engine Control (DEEC), an on-board general purpose computer, and an integrated architecture to allow all components to 'talk to each other.' Unlike standard F-15s, which have a mechanical and analog electronic flight control system, the HIDEC F-15 also had a dual-channel, fail-safe digital flight control system programmed in Pascal. It was linked to the Military Standard 1553B and a H009 data bus which tied all the other electronic systems together.

    Astronaut Alan Shepard (right) was one of 14 astronauts, 8 NASA test pilots, and 2 McDonnell test pilots who took part in simulator studies. Shepard flew the simulator on November 14, 1963. A.W. Vogeley wrote: 'Many of the astronauts have flown this simulator in support of the Gemini studies and they, without exception, appreciated the realism of the visual scene. The simulator has also been used in the development of pilot techniques to handle certain jet malfunctions in order that aborts could be avoided. In these situations large attitude changes are sometimes necessary and the false motion cues that were generated due to earth gravity were somewhat objectionable; however, the pilots were readily able to overlook these false motion cues in favor of the visual realism.' Roy F. Brissenden noted that: 'The basic Gemini control studies developed the necessary techniques and demonstrated the ability of human pilots to perform final space docking with the specified Gemini-Agena systems using only visual references. ... Results... showed that trained astronauts can effect the docking with direct acceleration control and even with jet malfunctions as long as good visual conditions exist.... Probably more important than data results was the early confidence that the astronauts themselves gained in their ability to perform the maneuver in the ultimate flight mission.' Shepard commented: 'I had the feeling tonight - a couple of times - that I was actually doing the space mission instead of the simulation. As I said before, I think it is a very good simulation.' Shepard also commented on piloting techniques. Most astronauts arrived at this same preferred technique: Shepard: 'I believe I have developed the preferred technique for these conditions and the technique appeared to me to be best was to come in slightly above the target so that I was able to use the longitudinal marks on the body of the target as a reference, particularly for a lateral translation and, of course, I

    PubMed Central

    2007-01-01

    Gerard E. Hogarty was a scholar and clinician whose career was dedicated to improving the lives of persons with schizophrenia through the rigorous development and testing of novel psychosocial treatment approaches. During the course of his career, he is credited with the development of many of the psychosocial treatments that have become the pillars of evidence-based practices for schizophrenia today. This review outlines the evolution of Hogarty's contributions to the development of psychosocial approaches for schizophrenia by presenting a chronological history of the 4 distinct treatments he developed during the course of his career. These include major role therapy, an early precursor to clinical case management; family psychoeducation, an approach to ally with and educate family members to reduce intrafamilial distress; personal therapy, a flexible, individual psychotherapy, aimed at teaching patients stress management and affective regulation techniques; and finally, cognitive enhancement therapy, a comprehensive, developmental approach to the remediation of social- and nonsocial-cognitive deficits. Each of these treatments built upon the findings of the previous one, and as a consequence, each significantly improved the lives of persons with schizophrenia and expanded the treatment possibilities available to such individuals. These efforts represent a lifelong dedication to advancing the treatment of schizophrenia through rigorous scientific inquiry and exemplify a unique combination of science and humanism that has left a lasting impact on the field and the lives of many individuals suffering from this disease.

    INTRODUCTION: Multiple factors of vulnerability may lead to development of abnormal social behaviour and to important psychiatric diseases. The psychopathological characteristics present at individual level can lead to a pattern of population groups that are subject to developing mental illness risks. MATERIAL AND METHODS: Multidisciplinary study (2009-2011) to assessing the current situation of mental health and identifying population risk groups for developing psychiatric disorders in a non-institutionalised population. We used the Woodworth Mathews Inventory (76 items) to a randomly selected sample of 1,200 men and women, residents in urban and rural areas. RESULTS: The extreme scores for emotiveness had a frequency more than triple for women, and we found a similar situation for obsessive-neurasthenic and depressive tendencies. People aging over 35 years had a double score (limit and poignancy) for depression than younger people, meanwhile correlation between age under 35 years and instability and antisocial tendencies is highly statistically significant (p<0.001), the frequency of extreme scores being almost double than in the older people. CONCLUSIONS: Female gender has a vulnerability for develop depressive and emotional disorders and age over 35 is also significant correlated with depressive tendencies. Younger people (under 35 years) are predisposed for pathological antisocial behaviour, fact revealed by the high scores for instability and antisocial tendencies. It is necessary to develop a program focused on the two risk categories to prevent the possible occurrence of psychiatric disorders. PMID:25729602

    The papers presented here, in this special volume dedicated to the memory of Alan Turner (1947-2012), provide a glimpse of the multi-faceted ways in which the mammalian fossil record can be investigated. The authors of contributions in this Special Issue are by no means an exhaustive list of his international collaborators and colleagues, and indeed, many are not represented here, but the contents cover many of the topics and issues that were of central archaeological and wider Quaternary mammalian interest to Alan. Although the papers are not intended to provide a comprehensive overview of all techniques that can be applied, the set nevertheless reveals a snapshot of the state-of-the-art and of some of the methods that have the potential to bring much more of the past to life. Alan always sought to move beyond the 'stamp-collecting' approach of simply listing which taxa were present at a site, attempting to elucidate what the presence of those animals might mean in terms of palaeoecology. In particular, the span of Alan's career has seen major advances in our understanding of Quaternary mammalian biostratigraphy and palaeobiogeography, the widespread application of novel techniques such as ancient DNA, the development of high-precision geochronology and the discovery of new hominin species. The papers presented here reflect those developments and highlight interdisciplinary approaches, from examination of sediments to careful measurements of the fossils themselves, from modelling the presence of taxa at particular points in the Quaternary to examination of the similarities and differences in fauna within and between sites.

  7. Novel methods for synthesizing halide-free alane without the formation of adducts

    Many of the current synthesis methods for aluminum hydride (alane—AlH3) involve reacting AlCl3 and LiAlH4 in solvents. The reaction requires the formation of an alane adduct such as AlH3ṡ[(C2H5)2O] prior to obtaining crystallized stable α-AlH3. This process requires several hours of pumping in a vacuum system to remove the ether and convert the alane etherate into stable α-alane. This crystallization process is both costly and hazardous because a large amount of highly flammable material (e.g. ether) is removed by vacuum pumps over several hours. Conversely, the work presented herein describes novel methods to synthesize adduct-free alane. It is demonstrated here that AlH3 can form by mixing AlCl3 and LiAlH4 in the solid state and heating to 75∘C; only α-AlH3 was obtained. The α-AlH3 product can be washed with minimal solvents leading to zero formation of alane adducts. In addition, the unwanted LiCl by-product is also removed during the solvent wash, resulting in halide-free α-alane. Although simply mixing and heating the reactants led to a 40% yield of alane, having the reactants compacted and mechanically pressed while heating increases the yield to 60% crystalline α-AlH3.

  8. Light metal alanates and amides for reversible hydrogen storage applications

    NASA Astrophysics Data System (ADS)

    Lu, Jun

    Hydrogen is undoubtedly one of the key alternatives to replace petroleum products as a clean energy carrier for both transportation and stationary applications. Although there have been numerous material systems studied as potential candidates for hydrogen storage applications, none of the materials known to date has demonstrated sufficient hydrogen capacity or efficiency in the required operating temperature ranges. There are still considerable opportunities for the discovery of new materials that could lead to advances in science as well as commercial technologies in this area. In this study, two new hydrogen-storage systems, i.e. alanate/amide and LiMgN, are investigated. Firstly, we found that if LiAlH4 and LiNH2 are allowed to react in a proper molar ratio, the LiH that forms as an intermediate product of the dehydrogenation of LiAlH4 can subsequently react with LiNH2 to release H2 at temperatures below 300°C, much lower than that without LiNH2. However, this system is only partially reversible. The difficulty of reversing the reaction is attributed to the irreversibility of the dehydrogenation reaction of LiAlH4 to Li3AlH6. Further experimental results showed that the reversible storage capacity of the combined alanate/amide material system is increased to 7.0 wt% under 300°C, if LiNH2 were reacted with Li3AlH6, instead of LiAlH4, in a 3:1 molar ratio. We also found that the re-formation of Li3AlH 6 depends strongly on the heating rate during the hydrogenation process. To improve the kinetic and thermodynamic properties of the Li-Al-N-H systems, the reaction between Li3AlH6 and Mg(NH2) 2 was studied based on the understanding of the destabilizing effect of amide on alanates. The Li-Al-Mg-N-H system would have better kinetic properties than the Li-Al-N-H system due to the addition of Mg, based on the published research results on the comparison between the Li-Mg-N-H and Li-N-H systems. A reversible 6.2 wt% H2 storage capacity has been demonstrated under the

    Alan Parkes was one of the most influential figures in the field of reproductive biology in the twentieth century. He had a huge impact on its growth and development during that time, and the legacy of his work still remains.His research was highly innovative and original because of his imaginative and inquiring mind, which, coupled with an entrepreneurial bent, led him into several very different fields and into unchartered waters. He played a leading role in the spectacular rise of reproductive endocrinology in Britain in the 1920s and 1930s when the nature and activity of many of the reproductive processes in animals and humans and was an essential factor in the development of methods for their control. Even more pioneering was his research in low-temperature biology in the years after World War II. This was sparked off by the discovery that glycerol had a remarkable property of protecting spermatozoa against damage during freezing and storage at very low temperatures. Far-reaching applications arose from this discovery, especially in the preservation of bull semen, which led to a worldwide revolution in artificial insemination in cattle. Later, many other cells and tissues were also successfully frozen, including red blood cells, ovarian tissue and bone marrow, and a new branch of biological science, which became known as 'cryobiology', was born, Effects of deep hypothermia, including freezing, on whole animals were also investigated at that time. Having successfully launched a new area of science, it was characteristic of Alan Parkes to switch to new fields. First he became interested in the influence of pheromones on mammalian reproduction. Then, resuming a long-standing interest in comparative aspects of reproductive physiology in British wild mammals, he became involved in the work of the Nuffield Unit of Tropical Animal Ecology in Uganda, where similar studies were carried out on African animals. Even after retirement from the academic field, he was for

    The second manned lunar landing mission, Apollo 12 launched from launch pad 39-A at Kennedy Space Center in Florida on November 14, 1969 via a Saturn Five launch vehicle. The Saturn V vehicle was developed by the Marshall Space Flight Center (MSFC) under the direction of Dr. Wernher von Braun. Aboard Apollo 12 was a crew of three astronauts: Alan L. Bean, pilot of the Lunar Module (LM), Intrepid; Richard Gordon, pilot of the Command Module (CM), Yankee Clipper; and Spacecraft Commander Charles Conrad. The LM, Intrepid, landed astronauts Conrad and Bean on the lunar surface in what's known as the Ocean of Storms while astronaut Richard Gordon piloted the CM, Yankee Clipper, in a parking orbit around the Moon. Their lunar soil activities included the deployment of the Apollo Lunar Surface Experiments Package (ALSEP), finding the unmanned Surveyor 3 that landed on the Moon on April 19, 1967, and collecting 75 pounds (34 kilograms) of rock samples. In this photograph, one of the astronauts on the Moon's surface is holding a container of lunar soil. The other astronaut is seen reflected in his helmet. Apollo 12 safely returned to Earth on November 24, 1969.

  11. How Alan Hirsig plans to play Arco chemical's strong hand

    With 1992 net income up 4%, to $195 million. Arco Chemical (Newtown Square, PA) held its own in a year when many of its petrochemical industry peers were mauled again. Arco Chemical president and CEO Alan R. Hirsig talked recently with CW about his growth strategies for the company, and about progress with his Manufacturing Excellence initiative, lauched in the wake of the 1990 Channelview, TX tragedy. Riding on faster growth in the Asia region, Hirsig expects to see Arco's regional sales mix shift in the next three years and sales to grow from 1992's $3.1 billion to $4 billion/year. The foundation for that growth continues to be Arco's core proprietary technology competence for making propylene oxide (PO) with coproduction and tert-butyl alcohol (TBA) - the key methyl tert-butyl ether (MTBE) feedstock, or styrene monomer. Arco claims a 28% share of world MTBE capacity, its 78,500-bbl/day capacity. He cites Jakarta, Bangkok, Mexico City, Milan, Turin, and Athens as examples of major cities where MTBE use in reformulated fuels is getting interest. Given what he views as Europe's traditional 10-year lag on the US in areas like catalytic mufflers and unleaded gasoline, he sees significant prospects in reformulated gasoline in that region in the coming years. Arco is also testing a proprietary TBA-based hydroperoxide in diesel fuels, which improves the cetane number and cleans up exhaust emissions, winning great interest in Tokyo. Also in the fuels area, Hirsig notes interest in ethyl tert-butyl ether production - which Arco launched in the US in December on a commercial scale - in France.

    Nowadays, hydrogen is highly interesting as an energy source, in particular in the automotive field. In fact, hydrogen is attractive as a fuel because it prevents air pollution and greenhouse emissions. One of the main problems with the utilization of hydrogen as a fuel is its on-board storage. The purpouse of this work was to develop a new hybrid material consisting of a polyaniline matrix with sodium alanate (NaAlH4) using a spray-drying process. The polyaniline used for this experiment was synthesized by following a well-established method for the synthesis of the emeraldine base form of polyaniline using dodecylbenzenesulfonic acid as dopant. Micro particles of polyaniline/sodium alanate hybrids with 30 and 50 wt% of sodium alanate were prepared by using a spray-drying technique. Dilute solutions of polyaniline/sodium alanate were first prepared, 10g of the solid materials were mixed with 350 ml of toluene under stirring at room temperature for 24h and the solutions were dried using spray-dryer (Büchi, Switzerland) with 115°C of an inlet temperature. The hybrids were analyzed by differential scanning calorimetry, FT-IR and scanning electron microscopy (SEM). The addition of sodium alanate decreased the glass transition temperature of the hybrids when compared to neat polyaniline. FT-IR spectrum analysis was performed to identify the bonding environment of the synthesized material and was observed that simply physically mixture occurred between polyaniline and sodium alanate. The SEM images of the hybrids showed the formation of microspheres with sodium alanate dispersed in the polymer matrix.

    ALAN (Artificial Light At Night) and LEDs have recently become major discussion topics in the areas of astronomy, light pollution, endangered species and human health to mention but a few. In years past, MH, LPS and HPS dominated night lighting with LPS and its associated narrow spectrum as the preferred source around observatories and shorelines. LEDs offer the ability to modify the spectrum, realize substantial energy savings and other associated benefits while meeting the requirements of the astronomy community.The primary concern of the different groups relates to blue light content of the LED. For astronomers, the molecular (Raleigh) scattering related to the blue light interferes with certain portions of the spectrum used for deep space studies. The ecologists studying various endangered species find blue and green light can be related to declining leatherback turtle population in certain areas of the world. Other animals ranging from bats to moths and other insects are now being studied to determine the effect of the blue light spectrum on their behavior. The impact of blue light on the human circadian rhythm and vision, especially in the older population, is being extensively studied today.This presentation will discuss the spectral power distribution (SPD) of various light sources, the performance of new LED solutions and how the SPD of these new LED’s can be adapted to address some of the issues raised by various constituencies. A discussion describing why some of the metrics used to describe standard lighting are not adequate for specifying the new LED solutions with the modified spectra will be included.Today, lighting plans and implementation are all too often based on opinions and limited data. The ensuing problems and repercussions make it imperative to collect accurate and thorough information. Data collection is now ongoing using a variety of techniques analyzing the “before” and “after” lighting results from the C of HI LED streetlight

    Knowledge of the relative stabilities of alane (AlH3) complexes with electron donors is essential for identifying hydrogen storage materials for vehicular applications that can be regenerated by off-board methods; however, almost no thermodynamic data are available to make this assessment. To fill this gap, we employed the G4(MP2) method to determine heats of formation, entropies, and Gibbs free energies of formation for 38 alane complexes with NH3−nRn (R = Me, Et; n = 0−3), pyridine, pyrazine, triethylenediamine (TEDA), quinuclidine, OH2−nRn (R = Me, Et; n = 0−2), dioxane, and tetrahydrofuran (THF). Monomer, bis, and selected dimer complex geometries were considered. Using these data, we computed the thermodynamics of the key formation and dehydrogenation reactions that would occur during hydrogen delivery and alane regeneration, from which trends in complex stability were identified. These predictions were tested by synthesizing six amine−alane complexes involving trimethylamine, triethylamine, dimethylethylamine, TEDA, quinuclidine, and hexamine and obtaining upper limits of ΔG° for their formation from metallic aluminum. Combining these computational and experimental results, we establish a criterion for complex stability relevant to hydrogen storage that can be used to assess potential ligands prior to attempting synthesis of the alane complex. On the basis of this, we conclude that only a subset of the tertiary amine complexes considered and none of the ether complexes can be successfully formed by direct reaction with aluminum and regenerated in an alane-based hydrogen storage system.

  8. Hydrogen release properties of lithium alanate for application to fuel cell propulsion systems

    NASA Astrophysics Data System (ADS)

    Corbo, P.; Migliardini, F.; Veneri, O.

    In this paper the results of an experimental study on LiAlH 4 (lithium alanate) as hydrogen source for fuel cell propulsion systems are reported. The compound examined in this work was selected as reference material for light metal hydrides, because of its high hydrogen content (10.5 wt.%) and interesting desorption kinetic properties at moderate temperatures. Thermal dynamic and kinetic of hydrogen release from this hydride were investigated using a fixed bed reactor to evaluate the effect of heating procedure, carrier gas flow rate and sample form. The aim of this study was to characterize the lithium alanate decomposition through the reaction steps leading to the formation of Li 3AlH 6 and LiH. A hydrogen tank was designed and realized to contain pellets of lithium alanate as feeding for a fuel cell propulsion system based on a 2-kW Polymeric Electrolyte Fuel Cell (PEFC) stack. The fuel cell system was integrated into the power train comprising DC-DC converter, energy storage systems and electric drive for moped applications (3 kW). The experiments on the power train were conducted on a test bench able to simulate the vehicle behaviour and road characteristics on specific driving cycles. In particular the efficiencies of individual components and overall power train were analyzed evidencing the energy requirements of the hydrogen storage material.

  12. Computational study of pristine and titanium-doped sodium alanates for hydrogen storage applications

    NASA Astrophysics Data System (ADS)

    Dathar, Gopi Krishna Phani

    The emphasis of this research is to study and elucidate the underlying mechanisms of reversible hydrogen storage in pristine and Ti-doped sodium aluminum hydrides using molecular modeling techniques. An early breakthrough in using complex metal hydrides as hydrogen storage materials is from the research on sodium alanates by Bogdanovic et al., in 1997 reporting reversible hydrogen storage is possible at moderate temperatures and pressures in transition metal doped sodium alanates. Anton reported titanium salts as the best catalysts compared to all other transition metal salts from his further research on transition metal doped sodium alanates. However, a few questions remained unanswered regarding the role of Ti in reversible hydrogen storage of sodium alanates with improved thermodynamics and kinetics of hydrogen desorption. The first question is about the position of transition metal dopants in the sodium aluminum hydride lattice. The position is investigated by identifying the possible sites for titanium dopants in NaAlH4 lattice and studying the structure and dynamics of possible compounds resulting from titanium doping in sodium alanates. The second question is the role of titanium dopants in improved thermodynamics of hydrogen desorption in Ti-doped NaAlH4. Though it is accepted in the literature that formation of TiAl alloys (Ti-Al and TiAl3) is favorable, reaction pathways are not clearly established. Furthermore, the source of aluminum for Ti-Al alloy formation is not clearly understood. The third question in this area is the role of titanium dopants in improved kinetics of hydrogen absorption and desorption in Ti-doped sodium alanates. This study is directed towards addressing the three longstanding questions in this area. Thermodynamic and kinetic pathways for hydrogen desorption in pristine NaAlH4 and formation of Ti-Al alloys in Ti-doped NaAlH 4, are elucidated to understand the underlying mechanisms of hydrogen desorption.

    Alan first trained as a telecom engineer, working for the GPO (General Post Office) which later became British Telecom. He never forgot this early training and was fascinated by how things worked - always happy to take something apart and fix it (although his attempt to close a large plate glass window with a geological hammer was not one of his successes). Following a few years as an engineer, he went to Sheffield University to study archaeology as a mature student in 1973. At this time Sheffield was a hotbed of prehistory with Graeme Barker, Robin Dennell and many others contributing to a truly research-led degree (with tutorials in the pub (well, it was the 1970s)) (Fig. 1). Alan's interest in bones developed at this time, and having graduated in 1976 he went on to take a PhD, supervised by Robin Dennell, on "Aspects of the palaeoecology of large predators, including man, during the British Upper Pleistocene, with particular emphasis on predator-prey relationships" which resulted in a life-long interest in the Carnivora and particularly hyaenas. Following his PhD, Alan moved to the Environmental Archaeology Unit at York to undertake a Science Research Council project on the morphometrics of domestic cattle and pigs from Coppergate and other major urban excavations in the city. Faced with a lot of measurements and statistics, Alan retained his interest in the animals themselves. The project also confirmed to Alan that prehistory was his metier, rather than the historic periods. Former York colleagues still fondly recall Alan's dry wit, and the day that he successfully put the irritating lab telephone beyond use with no externally visible trace of damage.

    In this article, we discuss Alan Marlatt’s contributions to the prevention and reduction of alcohol-related harms among college students. We consider Alan’s early research that later led to the development and evaluation of college student drinking programs, and examine Alan’s impact, both directly and indirectly through those he mentored and trained, as a scientist-practitioner. We review the recognition of the efficacy of Alan’s programs, including the Alcohol Skills Training Program (ASTP) and Brief Alcohol Screening and Intervention for College Students (BASICS), in addition to extensions of these interventions in more recent studies. Finally, we discuss how Alan’s work influences interventions with college student drinkers today, and how future directions will continue to be informed by his vision and values. PMID:25774117

    AlGaAs grown by metalorganic molecular beam epitaxy (MOMBE) has been problematic due to oxygen and carbon contamination, particularly when triethylaluminum (TEAl) has been used as the aluminum source. Consequently, we have investigated trimethylamine alane (TMAAl) as a potential replacement for the conventional metalorganic Al sources. AlGaAs films with excellent structural and optical properties have been grown with this source. Photoluminescence intensities from AlGaAs grown by MOMBE at 500 °C using TMAAl are comparable to those from material grown by metalorganic chemical vapor deposition at 675 °C using triethylaluminum (TMAl). Carbon and oxygen levels in MOMBE-grown AlGaAs are drastically reduced in comparison to similar films grown with TEAl.

  20. Discovering the Optimal Route for Alane Synthesis on Ti doped Al Surfaces Using Density Functional Theory Based Kinetic Monte Carlo Methods

    Karim, Altaf; Muckerman, James T.

    2010-03-01

    Issues such as catalytic dissociation of hydrogen and the mobility of alane species on Ti-doped Al surfaces are major challenges in the synthesis of aluminum hydride. Our recently developed modeling framework (DFT-based KMC simulation) enabled us to study the steady-state conditions of dissociative adsorption of hydrogen, its diffusion, and its reaction with Al adatoms leading to the formation of alane species on Ti-doped Al surfaces. Our studies show that the doping of Ti atoms in the top layer of Al surfaces significantly reduces the mobility of alane species. On the other hand, the doping of Ti atoms beneath the top layer of Al surfaces enhances the mobility of alane species. The arrangement of dopant Ti atoms in different layers not only affects the diffusion barriers of alane species but it also affects hydrogen dissociation barriers when Ti-Ti pairs are arranged in different ways in the top layer. Using our theoretical methods, we identified a few configurations of dopant Ti atoms having lower barriers for alane diffusion and hydrogen dissociation. Further, we discovered the optimal values of Ti concentration, temperature, and pressure under which the rate of alane formation is maximized.

    In his well-known prediction, Alan Turing stated that computer intelligence would surpass human intelligence by the year 2000. Although the Turing Test, as it became known, was devised to be played by one human against one computer, this is not a fair setup. Every human is a part of a social network, and a fairer comparison would be a contest between one human at the console and a network of computers behind the console. Around the year 2000, the number of web pages on the WWW overtook the number of neurons in the human brain. But these websites would be of little use without the ability to search for knowledge. By the year 2000 Google Inc. had become the search engine of choice, and the WWW became an intelligent entity. This was not without good reason. The basis for the search engine was the analysis of the ’network of knowledge’. The PageRank algorithm, linking information on the web according to the hierarchy of ‘link popularity’, continues to provide the basis for all of Google's web search tools. While PageRank was developed by Larry Page and Sergey Brin in 1996 as part of a research project about a new kind of search engine, PageRank is in its essence the key to representing and using static knowledge in an emergent intelligent system. Here I argue that Alan Turing was right, as hybrid human-computer internet machines have already surpassed our individual intelligence - this was done around the year 2000 by the Internet - the socially-minded, human-computer hybrid Homo computabilis-socialis. Ironically, the Internet's intelligence also emerged to a large extent from ‘exploiting’ humans - the key to the emergence of machine intelligence has been discussed by Marvin Minsky in his work on the foundations of intelligence through interacting agents’ knowledge. As a consequence, a decade and a half decade into the 21st century, we appear to be much better equipped to tackle the problem of the social origins of humanity - in particular thanks to the

    We study the electronic structure and vibrational modes of several amides M(NH2)n and alanates M(AlH4)n (M = K, Na, Li, Ca and Mg), focusing on the role of cation states. Calculated breathing stretching vibration modes for these compounds are compared with measured infrared and Raman spectra. In the amides, we find a significant tendency such that the breathing mode frequencies and the structural parameters of NH2 vary in accordance with the ionization energy of cation. The tendency may be explained by the strength in hybridization between cation orbitals and molecular orbitals of (NH2)-. The microscopic mechanism of correlations between the vibration frequencies and structural parameters is elucidated in relation to the electronic structure. A possible similar tendency in the alanates is also discussed.

He became the first American in space on May 5, 1961, in the Freedom 7 capsule, during a 15 minute suborbital trip reaching 115 miles altitude and 302 miles down the Atlantic tracking range. Grounded by an inner ear problem, he served as Chief of the Astronaut Office for several years. After an operation to correct the problem, he commanded the Apollo 14 moon mission in 1971. He retired as a Rear Admiral in 1974. Here, Alan Shepard offers his views on life support comedies and tragedies, going back to the moon, future drivers of the manned space flight program, the benefits of the space program, joint NASA and Russia missions, how his NASA experience affected his personal life, and the profitability of working with NASA.

    Doping NaAlH(4) with Ti-catalyst has produced a promising hydrogen storage system that can be reversibly operated at moderate temperature conditions. Of the various dopant precursors, TiCl(3) was well recognized due to its pronounced catalytic effect on the reversible dehydrogenation processes of sodium aluminium hydrides. Quite recently we experimentally found that TiF(3) was even better than TiCl(3) in terms of the critical hydrogen storage properties of the doped hydrides, in particular the dehydriding performance at Na(3)AlH(6)/NaH + Al step at moderate temperature. We present here the DFT calculation results of the TiF(3) or TiCl(3) doped Na(3)AlH(6). Our computational studies have demonstrated that F(-) and Cl(-) anions differ substantially from each other with regard to the state and function in the doped sodium aluminium hydride. In great contrast to the case of chloride doping where Cl(-) anion constitutes the "dead weight" NaCl, the fluoride doping results in a substitution of H(-) by F(-) anion in the hydride lattice and accordingly, a favorable thermodynamics adjustment. These results well explain the observed dehydriding performance associated with TiF(3)/TiCl(3)-doping. More significantly, the coupled computational and experimental efforts allow us to put forward a "functional anion" concept. This renews the current mechanism understanding in the catalytically enhanced sodium alanate. PMID:17356758

    Environmental factors acting during development of an individual may influence future health and disease susceptibility. Stressors, including altered diet, psychosocial stress, and immune challenge, during gestation can have negative consequences on the intrauterine environment and increase disease susceptibility of the developing fetus. The long-term effects on offspring have been observed in humans and include greater susceptibility to psychiatric disease, such as depression and anxiety disorders, and adverse metabolic conditions including obesity, diabetes and cardiovascular disease. Studies in my laboratory use rodent models and incorporate a multilevel approach to determine the behavioral, physiological, and neurobiological correlates of disease development as a consequence of early life stressors. The road I took in developing this research program was a rather circuitous one and navigating that path would not have been possible without the many mentors, colleagues, fellows and students who provided critical support. Although my name appears on the plaque of the Alan N. Epstein Research Award, I share this with all those I had the privilege of working with along that road, as briefly summarized in this article.

    Peptidergic neurons are a group of neuronal cells that synthesize and secrete peptides to regulate a variety of biological processes. To identify genes controlling the development and function of peptidergic neurons, we conducted a screen of 545 splice-trap lines and identified 28 loci that drove expression in peptidergic neurons when crossed to a GFP reporter transgene. Among these lines, an insertion in the alan shepard (shep) gene drove expression specifically in most peptidergic neurons. shep transcripts and SHEP proteins were detected primarily and broadly in the central nervous system (CNS) in embryos, and this expression continued into the adult stage. Loss of shep resulted in late pupal lethality, reduced adult life span, wing expansion defects, uncoordinated adult locomotor activities, rejection of males by virgin females, and reduced neuropil area and reduced levels of multiple presynaptic markers throughout the adult CNS. Examination of the bursicon neurons in shep mutant pharate adults revealed smaller somata and fewer axonal branches and boutons, and all of these cellular phenotypes were fully rescued by expression of the most abundant wild-type shep isoform. In contrast to shep mutant animals at the pharate adult stage, shep mutant larvae displayed normal bursicon neuron morphologies. Similarly, shep mutant adults were uncoordinated and weak, while shep mutant larvae displayed largely, although not entirely, normal locomotor behavior. Thus, shep played an important role in the metamorphic development of many neurons. PMID:24931409

    The growth of III-V Al-containing epitaxial structures by MOMBE has proven difficult due to the excessive oxygen and carbon contamination introduced by the Al source. Triethylaluminum (TEAl), the most commonly used precursor, produces unacceptable levels of both impurities in AlGaAs grown by MOMBE. We have grown AlGaAs films with excellent structural and optical properties using a novel source, trimethylamine alane (TMAAl). Photoluminescence intensities from AlGaAs grown by MOMBE at 500δC with TMAAl are comparable to those from material grown by MOCVD at 675δC using trimethylaluminum. In addition, carbon and oxygen levels in AlGaAs, as detected by SIMS, are drastically reduced in comparison to similar films produced with TEAl. We shall also discuss the effects of growth temperature and Al content on carbon and oxygen incorporation as well as crystallinity and provide preliminary device results on GaAs/AlGaAs HBTs prepared by the MOMBE technique.

    Light alkaline and alkaline-earth metal hydrides such as amides M(NH2)n and alanates M(AlH4)n (M=K, Na, Li, Ca, and Mg) have attracted a growing interest as reversible hydrogen storage materials recently because of their innately high hydrogen contents. [1, 2] We study the electronic structure of the amides and alanates with different cations, focusing on the role of cation states from first-principles calculations based on the all-electron FLAPW method. Calculated breathing stretch vibration modes for these compounds are compared with measured infrared and Raman spectra. In the amides, we find a significant tendency such that the breathing stretch vibration frequencies and the structural parameters of NH2 vary in accordance with the ionization energy of cation, which may be explained by the strength in hybridization between cation orbitals and molecular orbitals of (NH2)^-. We elucidate the microscopic mechanism of correlations between the breathing stretch vibration frequencies of N-H and structural parameters by analyzing the calculated electronic structure from a view point of the molecular-orbitals. A similar tendency in the alanates is also discussed. [1] P. Chen, Z. Xiong, J. Luo, J. Lin and K.L. Tan, Nature 420, 302 (2002). [2] B. Bogdanovi and M. Schwickardi, J.

    We report the results of an experimental and theoretical study of hydrogen storage in sodium alanate (NaAlH{sub 4}). Reversible hydrogen storage in this material is dependent on the presence of 2-4% Ti dopant. Our combined study shows that the role of Ti may be linked entirely to Ti-containing active catalytic sites in the metallic Al phase present in the dehydrogenated NaAlH{sub 4}. The EXAFS data presented here show that dehydrogenated samples contain a highly disordered distribution of Ti-Al distances with no long-range order beyond the second coordination sphere. We have used density functional theory techniques to calculate the chemical potential of possible Ti arrangements on an Al(001) surface for Ti coverages ranging from 0.125 to 0.5 monolayer (ML) and have identified those that can chemisorb molecular hydrogen via spontaneous or only moderately activated pathways. The chemisorption process exhibits a characteristic nodal symmetry property for the low-barrier sites: the incipient doped surface-H2 adduct's highest occupied molecular orbital (HOMO) incorporates the {sigma}* antibonding molecular orbital of hydrogen, allowing the transfer of charge density from the surface to dissociate the molecular hydrogen. This work also proposes a plausible mechanism for the transport of an aluminum hydride species back into the NaH lattice that is supported by Car-Parrinello molecular dynamics (CPMD) simulations of the stability and mobility of aluminum clusters (alanes) on Al(001). As an experimental validation of the proposed role of titanium and the subsequent diffusion of alanes, we demonstrate experimentally that AlH{sub 3} reacts with NaH to form NaAlH{sub 4} without any requirement of a catalyst or hydrogen overpressure.

    Data on the distribution of radiolarians and planktonic and benthic foraminifers are obtained for the first time from the Alan-Kyr Section (Coniacian-Campanian), in the central regions of the Crimean Mountains. Radiolarian biostrata, previously established from Ak-Kaya Mountain (central regions of the Crimean Mountains) were traced: Alievium praegallowayi-Crucella plana (upper Coniacian-lower Santonian), Alievium gallowayi-Crucella espartoensis (upper Santonian without the topmost part), and Dictyocephalus (Dictyocryphalus) (?) legumen-Spongosaturninus parvulus (upper part of the upper Santonian). Radiolarians from the Santonian-Campanian boundary beds of the Crimean Mountains are studied for the first time, and Prunobrachium sp. ex gr. crassum-Diacanthocapsa acanthica Beds (uppermost Santonian-lower Campanian) are recognized. Bolivinoides strigillatus Beds (upper Santonian) and Stensioeina pommerana-Anomalinoides (?) insignis Beds (upper part of the upper Santonian-lower part of the lower Campanian) are recognized. Eouvigerina aspera denticulocarinata Beds (middle and upper parts of the lower Campanian) and Angulogavelinella gracilis Beds (upper part of the upper Campanian are recognized on the basis of benthic foraminifers. These beds correspond to the synchronous biostrata of the East European Platform and Mangyshlak. Marginotruncana coronata- Concavatotruncana concavata Beds (Coniacian-upper Santonian), Globotruncanita elevata Beds (terminal Santonian), and Globotruncana arca Beds (lower Campanian) are recognized on the basis of planktonic foraminifers. Radiolarian and planktonic and benthic foraminiferal data agree with one another. The position of the Santonian-Campanian boundary in the Alan-Kyr Section, which is located stratigraphically above the levels of the latest occurrence of Concavatotruncana concavata and representatives of the genus Marginotruncana, is refined, i.e., at the level of the first appearance of Globotruncana arca.

    Safe and efficient hydrogen storage is a significant challenge inhibiting the use of hydrogen as a primary energy carrier. Although energy storage performance properties are critical to the success of solid-state hydrogen storage systems, operator and user safety is of highest importance when designing and implementing consumer products. As researchers are now integrating high energy density solid materials into hydrogen storage systems, quantification of the hazards associated with the operation and handling of these materials becomes imperative. The experimental effort presented in this paper focuses on identifying the hazards associated with producing, storing, and handling sodium alanates, and thus allowing for the development and implementation of hazard mitigation procedures. The chemical changes of sodium alanates associated with exposure to oxygen and water vapor have been characterized by thermal decomposition analysis using simultaneous thermogravimetric modulated beam mass spectrometry (STMBMS) and X-ray diffraction methods. Partial oxidation of sodium alanates, an alkali metal complex hydride, results in destabilization of the remaining hydrogen-containing material. At temperatures below 70 C, reaction of sodium alanate with water generates potentially combustible mixtures of H{sub 2} and O{sub 2}. In addition to identifying the reaction hazards associated with the oxidation of alkali-metal containing complex hydrides, potential treatment methods are identified that chemically stabilize the oxidized material and reduce the hazard associated with handling the contaminated metal hydrides.

    After more than a decade of intense research on NaAlH(4) doped with transition metals as hydrogen storage material, the actual mechanism of the decomposition and rehydrogenation reaction is still unclear. Early on, monomeric AlH(3) was named as a possible transport shuttle for aluminium, but never observed experimentally. Here we report for the first time the trapping of volatile AlH(3) produced during the decomposition of undoped NaAlH(4) by an adduct of sodium alanate and crown ether. The resulting Al(2)H(7)(-) anion was identified by solid-state (27)Al NMR spectroscopy. Based on this indirect evidence of volatile alane, we present a simple description of the processes occurring during the reversible dehydrogenation of NaAlH(4). PMID:21879065

  17. Towards understanding a mechanism for reversible hydrogen storage: theoretical study of transition metal catalysed dehydrogenation of sodium alanate.

    On the basis of density functional theory and coupled-cluster CCSD(T) calculations we propose a mechanism of the dehydrogenation of transition metal doped sodium alanate. Insertion of two early 3d-transition metals, scandium and titanium, both of which are promising catalysts for reversible hydrogen storage in light metal hydrides, is compared. The mechanism is deduced from studies on the decomposition of a model system consisting of one transition metal atom and two NaAlH(4) units. Subsequently, the significance of such minimal cluster model systems to the real materials is tested by embedding the systems into the surface of the NaAlH(4) crystal. It is found that the dehydrogenation proceeds via breaking of the bridge H-Al bond and consequent formation of intermediate coordination compounds in which the H(2) molecule is side-on (eta(2)-) bonded to the transition metal centre. The total barrier to the H(2) release is thus dependent upon both the strength of the Al-H bond to be broken and the depth of the coordinative potential. The analogous mechanism applies for the recognized three successive dehydrogenation steps. The gas-phase model structures embedded into the surface of the NaAlH(4) crystal exhibit an unambiguous kinetic stability and their general geometric features remain largely unchanged. PMID:20379493

    We investigated the dependence of the background impurity incorporation on growth conditions and optical properties of undoped AlGaAs grown by gas source molecular beam epitaxy using trimethylamine alane (TMAAl), triethylgallium, and arsine. The use of TMAAl enabled us to reduce the carbon concentration (7× 1016 cm-3) to over one order of magnitude less than that using triethylaluminum (TEAl). The 77 K photoluminescence spectrum of undoped AlGaAs grown using TMAAl was dominated by excitonic band-edge emission not observable in AlGaAs grown using TEAl. Furthermore, we report for the first time the doping characteristics of n-type AlGaAs grown using disilane (Si2H6) as an n-type gaseous dopant source together with TMAAl. The carrier concentration (5× 1017--3× 1018 cm-3) in n-AlxGa1-xAs (x{=}0.09--0.27) was reliably controlled and showed the same Si2H6 flow rate dependence as that of GaAs. The activation efficiency of silicon was more than 60%. We demonstrated the excellent n-type doping characteristics by uisng TMAAl.

    We used surface photo-absorption (SPA) to study trimethylamine alane (TMAA) and dimethylamine gallane (DMAG) decomposition processes on a substrate surface in metal-organic chemical vapor deposition. The decomposition onset temperatures of these group III hydride sources correspond to the substrate temperature at which the SPA reflectivity starts to increase during the supply of the group III source onto a group V stabilized surface. It was found that TMAA and DMAG start to decompose at about 150°C on an As-stabilized surface, which is much lower than the decomposition onsets of trialkyl Al and Ga compounds. Low temperature photoluminescence spectra exhibit dominant excitionic emissions for GaAs layers grown by DMAG at substrate temperatures above 400°C, indicating that carbon incorporation and the crystal quality deterioration due to incomplete decomposition on surface is much suppressed by using DMAG. A comparison of AlGaAs photoluminescence between layers by TMAA/triethylgallium and triethylaluminum/triethylgallium shows that the band-to-carbon acceptor transition is greatly reduced by using TMAA. TMAA and DMAG were verified to be promising group III sources for low-temperature and high-purity growth with low-carbon incorporation.

    In this lecture, Dr. Henry Morgentaler describes how he led the fight to make abortion sage and legal in Canada. In 1967, the Canadian government began exploring possible changes in the abortion law, which at that made abortion a major crime. As president of the Humanist Fellowship of Montreal, Morgentaler presented a brief to House of Commons calling for abortion on request. His appeal attracted great media attention, and soon women started coming to Morgentaler's office seeking abortions. Risking prosecution, Morgentaler agreed to perform the operations (in the process becoming the first doctor in North America to use the vacuum suction technique). His abortion practice grew rapidly. In 1969, the Canadian government made abortion legal if approved by a committee of 3 doctors and if performed in a hospital. Though an improvement over the previous law, the new abortion law still had many deficiencies, most notably: it discriminated against women in rural areas (where the only available hospitals were Catholic), and it made getting an abortion a lengthy process, making the procedure more dangerous. Still campaigning vigorously performing abortions in his Montreal clinic, Morgentaler on charges of illegal abortion by the Quebec government. For the next 6 years, Morgentaler rode a legal roller coaster -- 3 jury acquittals were overturned or disregarded -- serving 10 months in prison throughout the ordeal (the legal battle produced the so-called Morgentaler Amendment, which stipulates that court cannot substitute its own verdict for a jury verdict of not guilty). In 1976, Quebec ended its battle with Morgentaler, who in turn launched his campaign to the rest of Canada. And in 1988, the Canadian Supreme Court rescinded the abortion low, thus affirming the dignity and equality of women. PMID:12284999

  2. Studies of gas phase reactions, nucleation and growth mechanisms of plasma promoted chemical vapor deposition of aluminum using dimethylethylamine alane as source percursor

    NASA Astrophysics Data System (ADS)

    Knorr, Andreas H.

    The work presented herein focuses on the use of plasma promoted chemical vapor deposition (PPCVD) of aluminum (Al) using dimethylethylamine alane (DMEAA) as source precursor to provide an integrated, low temperature alternative to currently employed Al deposition methods in ultra large sale integration ULSI multilevel metal wiring schemes. In this respect, key findings are reported and discussed from critical scientific and technical aspects of an research and development effort, which was successfully executed to identify a viable Al CVD deposition process. In this respect, advanced atomic scale analytical techniques were successfully employed to characterize the PPCVD deposition process at the molecular level, and document the dependence of film's structural and compositional properties on key process parameters. This led to the development and optimization of a PPCVD Al process for ULSI applications. In addition, gas phase quadrupole mass spectrometry (QMS) was employed to study the gas phase evolution during TCVD and PPCVD in order to gain a thorough understanding of the potential chemical and physical reactions that could occur in the gas phase and derive corresponding optimized reaction pathways for both CVD processes. Key reaction mechanisms involved in thermal and plasma promoted CVD as a function of processing parameters were investigated, including the role of hydrogen plasma in providing an efficient pathway to aluminum nucleation and growth. The resulting reaction mechanisms were then employed to identify the most likely precursor decomposition pathways and explore relevant implications for thermal and plasma promoted CVD Al. Furthermore, the nucleation and growth of Al in both TCVD and PPCVD were thoroughly characterized. Time evolution studies were carried out employing a variety of relevant liners and seed layers under selected surface chemical states. The surface morphology of the resulting films were analyzed by means of scanning probe microscopy

    The study of Einstein's theory of general relativity experienced a renaissance beginning in the early 1960s. Prior to this resurgence of interest, general relativity was isolated from mainstream physics-admired for its elegance, perhaps, but only from a distance. The generation of students who risked their careers by entering this neglected field has now reached the age of festschrifts. In June of 2000, Caltech hosted "Kipfest," a conference in honor of Kip Thorne's 60th birthday. Thorne started graduate school at Princeton in 1962 and began research in general relativity under John Wheeler's guidance in the heady early days of the renaissance. Since then, he has played a prominent role in general relativity: as co-author of the influential textbook Gravitation, as a leader in research regarding astrophysical applications of Einstein's theory, and as a co-founder and chief advocate for the Laser Interferometer Gravitational Wave Observatory (LIGO), to mention a few aspects of his far-reaching work. "Kipfest" included 14 speakers discussing fields to which Thorne has contributed. But the conference also reflected Thorne's long-standing commitment to communicating science to a general audience: Igor Novikov, Stephen Hawking, Timothy Ferris, and Alan Lightman gave popular talks at "Kipfest," with Thorne himself tricked into delivering a fifth. The Future of Spacetime gathers adaptations of these five lectures, along with a lengthy introductory essay by Richard Price.

    Important limitations in the application of light metal hydrides for hydrogen storage are slow kinetics and poor reversibility. To alleviate these problems doping and ball-milling are commonly applied, for NaAlH 4 leading to particle sizes down to 150 nm. By wet-chemical synthesis we have prepared carbon nanofiber-supported NaAlH 4 with discrete particle size ranges of 1-10 microm, 19-30 nm, and 2-10 nm. The hydrogen desorption temperatures and activation energies decreased from 186 degrees C and 116 kJ.mol (-1) for the largest particles to 70 degrees C and 58 kJ.mol (-1) for the smallest particles. In addition, decreasing particle sizes lowered the pressures needed for reloading. This reported size-performance correlation for NaAlH 4 may guide hydrogen storage research for a wide range of nanostructured light (metal) hydrides. PMID:18459778

  18. A First Principles Study of Mass Transport in the Dehydrogenation of Lithium Amides and Lithium Alanates

    NASA Astrophysics Data System (ADS)

    Rolih, Biljana

    The pursuit of competitive alternatives to energy derived from the combustion of fossil fuels, has led to a great variety of new technologies. Exceptional develop- ments in electrochemical storage and production promise to lead to clean burning passenger vehicles. The high chemical density of a hydrogen fuel cell enables it to meet current standards for driving range and weight required of vehicles, making it an excellent candidate for universal application in the automotive industry. One of the biggest obstacles the fuel cell industry has yet to overcome is the means of practical hydrogen storage. Solid state metal hydrides are a class of materials that show potential for both economic and practical hydrogen storage. The search for the ideal metal hydride is defined by thermodynamic and kinetic constraints, since the requirements for a viable system are a rapid release of hydrogen in the temperature range of -40°C, to 80°C. First-principles density functional theory is an excellent method for gaining insight into the kinetics and thermodynamics of metal hydride solid state reactions. In the work presented here, density functional theory is used to explore formation energies, concentrations and migration barriers of metal hydrides. In particular, the following systems were analyzed: • Li - N - H It is well known that the reactive hydride composite LiNH 2 + LiH reversibly releases a large amount of hydrogen gas, with more favorable thermodynamics than LiNH2 alone. Kinetics of mass transport during the dehydrogenation of LiNH2 + LiH are investigated. A model is developed for determining activation energies of native defects in bulk crystals. In order to establish whether mass transport is the rate-limiting step in the dehydrogenation reaction, results are compared to experimental values. • Li - Al - H Kinetics of mass transport during the dehydrogenation of the metal hydride LiAlH2 are investigated. It is known that LiAlH4 endothermically decomposes via a two step reaction. The kinetics of both steps in the reactions are studied. Results are compared to experiments in order to determine whether mass transport is the rate-limiting process in the reactions.

The authors have designed the workbook to differ from its predecessors in two ways: the target audience is introductory organic chemistry students, and a CD-ROM containing files of molecules and data replaces the need for expensive molecular modeling software. It also differs from its predecessors in that the exercises in it are not really molecular modeling experiments. Instead, students are introduced to the field by viewing the results of computational work stored on the CD-ROM. The workbook is divided into 21 chapters, each of which covers a topic encountered in introductory-level organic chemistry. The sequence of chapters follows the sequence of topics that instructors of introductory organic courses might employ, allowing the workbook to be used with most modern organic chemistry texts. The heart of the workbook, though, is the CD-ROM included with the book. It contains files of molecules and their accompanying computational results as well as Spartan View, a software package that allows these models to be visualized. Although it does not allow actual calculations to be performed, Spartan View permits the user to rotate molecules, intermediates, and transition states and retrieve "precalculated" values of bond and dihedral angles, bond lengths, energies, dipole moments, charge, and frequency of vibration. Spartan View also allows the user to search molecules and intermediates for electron-rich or electron-poor regions by showing electrostatic potential as well as HOMOs and LUMOs. Some files allow for animation of reactions or conformational changes. Note, however, that since the data are just stored on the CD-ROM, not all the data are available for all files. Although performing calculations is not an option, Spartan View can be used to display models and data obtained using Spartan or MacSpartan and stored on a disk. In this way, student exercises can be customized by the instructor or the instructor can prepare customized examples for use in lecture. Each chapter in the workbook contains a series of 3 to 17 exercises that use models and associated data contained on the accompanying CD-ROM. The exercises are not simply cookbook procedures in which the student is directed how to solve a problem. Instead, the authors provide background in a two-part tutorial and several essays that describe the information that can be obtained through molecular modeling, and then introduce a problem in organic chemistry that can be addressed using molecular modeling. The student is left to determine how best to obtain the requested data. For example, an exercise in the chapter Acids & Bases directs the student to determine the atomic charges and view the electrostatic potential map of the conjugate bases of three organic acids. The student is not, however, told which menu to pull or button to push. At the end of the exercise, the student is directed to compare the reactivity of the acids with the data collected from Spartan View. The exercises are relatively easy to complete after spending a few minutes with the tutorials, and many require students to compare the results of calculations with the reactivity of the molecules as discussed in the traditional lecture portion of the course. In this sense, the workbook provides a meaningful link between molecular modeling exercises outside of class and activities in the classroom. While some exercises involve comparing the energies of intermediates or transition states, others are more like videos of processes. Instructors will find many of these to be useful as visual aids in lecture. Mechanisms of Ring Inversion, for example, allows the instructor to show the stepwise ring flip of cyclohexane. Although some of the animations are very similar to those contained on CD-ROMs that sometimes accompany textbooks, the exercises in this workbook allow for the retrieval of data such as the energies of the various conformations cyclohexane. Not only can the student see the stepwise conversion of one chair conformation into another, but the changes in energy as the ring flip occurs are available. Also, unlike many of the visualizations on the CD-ROMs packaged with textbooks, these give the student control over the orientation of the structures on the screen, allowing views from numerous angles. The possibility of the instructor's customizing the exercises adds to the appeal of this workbook. In reviewing this book, I noted a couple of problems. The energy of molecules is presented in hartrees or atomic units (au). Although a factor is given for converting these values into the more familiar kcal/mol or kJ/mol, wouldn't it be easier to use these results if they were given in the units that are more typically used in introductory organic chemistry texts? Similarly, a number of exercises ask the student to plot data that they have calculated in the exercise. However, no routine for plotting the data is included with Spartan View and students must go through the cumbersome process of copying the values and preparing the plots using another program or by hand. And, finally, in Tutorial B, animations are introduced by showing "the SN2 displacement of chloride in tert-butyl chloride by bromide." Although the animation shows an SN1 mechanism with the C-Cl bond breaking before approach of the incoming bromide ion, students who are new to organic mechanisms will be misled by the erroneous description in the workbook. Although instructors may want to carefully consider whether to add an additional 30 to the already high cost of required texts, this workbook provides a unique and potentially valuable addition to the introductory organic chemistry course. With many exercises involving the visualization of electrostatic potentials and HOMOs and LUMOs, it adds an increased presence of physical organic chemistry in the introductory course. And, although the exercises are not really molecular modeling, this workbook also provides a low-cost introduction to the field without the considerable cost of modeling software. If Spartan or MacSpartan is already available in the department, the possible tie-in with the workbook and the capability to project the results should make this an attractive addition to any instructor's repertoire of visualization tools for lecture. The Molecular Modeling Workbook for Organic Chemistry is definitely worthy of consideration by anyone interested in adding molecular modeling to the organic course.

  9. Do rapid 'superbug' tests pay off? Balance the costs and benefits of leading-edge technology. Interview by Alan Joch.

    Morgan, Margie Ann

    2009-02-01

    As hospitals become increasingly sensitive to the health and financial consequences of health care-associated infections (HAIs), a new generation of molecular-based testing technologies promises to significantly shorten the time required to identify "superbugs" and other bacterial infections. The leading-edge techniques promise to reduce costs by helping hospitals quickly determine which patients to isolate because they carry active methicillin-resistant Staphylococcus aureus (MRSA) infections, for example, or which ones to release from prophylactic isolation because they ultimately tested negative for a dangerous infection. But diagnostic speed comes at a price--the costs to perform molecular tests are significantly higher than conventional methods. This challenges hospitals to balance health care expenses with medical efficacy, says molecular testing veteran Margie Morgan, Ph.D., scientific director at Cedars-Sinai Medical Center, Los Angeles. "The rapid methods can be extreme time savers and possibly help a great deal with the isolation of patients. But some of the tests may cost five times what manual methods might be, so there is a price for seeing so much of a reduction in time," she says. PMID:19288674

    Ab initio calculations are performed to investigate the structural stability, electronic structure and mechanical properties of BeAlH{sub 5} for monoclinic crystal structures with two different types of space group namely P2{sub 1} and C{sub 2}/c. Among the considered structures monoclinic (P2{sub 1}) phase is found to be the most stable at ambient condition. The structural phase transition from monoclinic (P2{sub 1}) to monoclinic (C{sub 2}/c) phase is observed in BeAlH{sub 5}. The electronic structure reveals that this compound is insulator. The calculated elastic constants indicate that this material is mechanically stable at ambient condition.

    Populations and infrastructure along much of the northeastern coast of the United States will become increasingly vulnerable to the impacts of rising sea level and storm surges over the coming century. This vulnerability is amplified by regional land subsidence and likely also by shifts in ocean circulation. Building upon recent studies for the New York City Panel on Climate Change (NPCC), New York State ClimAid assessment, and the latest U.S. National Climate Assessment, we report new regional sea level rise projections based on the latest CMIP-5 global climate models (GCMs) and RCP emission scenarios, adjusted for revised glacial ice melt contributions, and other factors such as gravitational effects, land water storage, and changes in the Atlantic Meriodional Overturning Circulation (AMOC). Over the coming two years, GCM-derived sea level outputs for future decades will be utilized in risk assessments for coastal flooding in New York City, Boston, and Philadelphia, as part of the Consortium for Climate Risk in the Urban Northeast-RISA project. The Stevens Institute Estuarine and Coastal Ocean Model (sECOM) will be used to produce best estimates (including uncertainty ranges) of sea level rise impacts for a wide range of tropical and extra-tropical cyclones for the 2010s, 2050s, and 2080s. Major improvements over prior studies include (a) the use of a detailed, extensively validated ocean model, and (b) inclusion of rainfall and river flow influences on coastal flooding, which affect flood levels in enclosed tidal waterways (e.g., the Hudson and Delaware Rivers), and which are also likely important in coastal confluence zones of impermeable urbanized watersheds. In addition to the sea level rise results, we present initial model validation results for historical storms.

  5. ALUMINUM HYDRIDE: A REVERSIBLE STORAGE MATERIAL FOR HYDROGEN STORAGE

    SciTech Connect

    2009-01-09

    One of the challenges of implementing the hydrogen economy is finding a suitable solid H{sub 2} storage material. Aluminium (alane, AlH{sub 3}) hydride has been examined as a potential hydrogen storage material because of its high weight capacity, low discharge temperature, and volumetric density. Recycling the dehydride material has however precluded AlH{sub 3} from being implemented due to the large pressures required (>10{sup 5} bar H{sub 2} at 25 C) and the thermodynamic expense of chemical synthesis. A reversible cycle to form alane electrochemically using NaAlH{sub 4} in THF been successfully demonstrated. Alane is isolated as the triethylamine (TEA) adduct and converted to unsolvated alane by heating under vacuum. To complete the cycle, the starting alanate can be regenerated by direct hydrogenation of the dehydrided alane and the alkali hydride (NaH) This novel reversible cycle opens the door for alane to fuel the hydrogen economy.

    areas of physics-based science and technology. Can materials science be made intellectually more exciting and mind-stretching for our students? In this special issue we present several articles by researchers in less-than-familiar but important areas of materials science and technology. Following a review by Mathew Philip of some of the basic atomic theory which underlies materials science, Jose Silva looks at how artificial diamonds can be made and at how we can apply this exotic material (other than on fingers and around necks). Alan Piercy reviews the field of giant magnetostrictive materials, which, when magnetized, change dimensions hundreds or even thousands of times more than traditional ferromagnetics. David Pettifor provides a nicely interdisciplinary overview of how computer simulations, from the subatomic to the macroscopic level, can be used to help in the design of new materials for such things as turbine blades. Adrian Rennie offers a much-requested written version of the entertaining 1995/6 IOP Schools Lecture on the physics of polymers. (We had hoped to include an article by Professor Colin Gough of Birmingham University on High Temperatue Superconductors, but for technical reasons this has had to be postponed until a future issue.) Finally, there are two articles describing an initiative which will have a direct practical impact on the teaching and learning of `Materials' in the UK. Karen Davies describes the exciting new Materials Gallery due to be opened at the Science Museum as this issue goes to press in May 1997 (no coincidence!), and David Sang provides details of how the new gallery has been linked directly with the GNVQ curriculum, and can certainly be exploited more widely in our physics and technology teaching. Perhaps this can help provide the missing 'zing' that materials science at present seems to lack.

    2015-06-01

    It has been reported that excessive artificial light at night (ALAN) could harm human health since it disturbs the natural bio-rhythm and sleep. Such conditions can lead to various diseases, including cancer. In this study, we have evaluated the association between ALAN and prevalence rates of cancer in females on a regional basis, after adjusting for other risk factors, including obesity, smoking, alcohol consumption rates and PM10 levels. The prevalence rates for breast cancer were found to be significantly associated with ALAN in urban and rural areas. Furthermore, no association was found with ALAN in female lung, liver, cervical, gastric and colon cancer. Despite the limitations of performing ecological studies, this report suggests that ALAN might be a risk factor for breast cancer, even in rural areas. PMID:25955405

  14. Advances in the electrochemical regeneration of aluminum hydride

    NASA Astrophysics Data System (ADS)

    Martínez-Rodríguez, Michael J.; García-Díaz, Brenda L.; Teprovich, Joseph A.; Knight, Douglas A.; Zidan, Ragaiy

    2012-03-01

    In previous work, a reversible cycle that uses electrolysis and catalytic hydrogenation of spent Al(s) for the regeneration of alane (AlH3) was reported. In this study, the electrochemical synthesis of alane is improved. Advances in the electrochemical regeneration of alane have been achieved via the use of lithium aluminum hydride (LiAlH4) and lithium chloride (LiCl). Lithium chloride reacts in a cyclic process and functions as an electro-catalytic additive that enhances the electrochemical process by increasing the cell efficiency and the alane production. Electrochemical techniques are used to show that the increased rate of alane generation is due to the electro-catalytic effect of lithium chloride, rather than an electrolyte enhanced effect.

    Experimental efforts by the LLNL/Ohio State radioactive ion beam collaboration are described. We are presently focusing on some reactions which are of great importance in the newly proposed inhomogeneous big bang cosmological models [G.M. Fuller, G.J. Mathews and C.R. Alcock, in: Origin and Distribution of the Elements, ed. G.J. Mathews (World Scientific, Singapore, 1987)]. Specifically we are using our system to make beams of 8Li for measurements of the 8Li(d, n)9Be and 8Li(a, n)11B cross sections. These are the key reactions which determine the production of heavy (A > 12) elements during the era of big bang nucleosynthesis, and thus the initial composition of stars and subsequent stellar isotope production. Plans for future experiments, including the measurement of the 7Be(p, γ)8B cross section will be discussed.

    It is well known, in the low level laser therapy, that an important number of patients exhibit positive results at PLACEBO treatment. That is why we decided to analyze the psychological profile of 156 patients presented rheumatical diseases, divided into tow groups: laser group and PLACEBO group. We applied the Woodworth-Mathews test to all patients before the laser treatment. This is a test for identification of the abnormal tendencies in the normal human behavior. Finally, following the PLACEBO exposure, we noticed that the patients' emotional tendencies and psychological instability had a strong influence on the obtained good results. We conclude that the Woodworth- Mathews test is useful to anticipate the possible false/positive results in the real treatment. Nevertheless it may also be used from the psychological point of view.

    Mathew et al. propose that many candidate genes identified in our study may reflect the events in the choroid plexus (ChP) potentially included in hippocampal samples. We reanalyze our data and find that the ChP inclusion is unlikely to affect our major conclusions regarding the basal suppression of translational machinery or the early translational repression (at 5 to 10 minutes). As Mathew et al. examined for a subset of genes at 4 hours, we agree that the late suppression may partly reflect the events in the ChP. Although the precise contribution of anatomical sources remains to be clarified, our behavioral analyses indicate that the late-phase suppression of these genes may contribute to memory formation.

  18. Toledo School of Translators and their influence on anatomical terminology.

    PubMed

    Arráez-Aybar, Luis-Alfonso; Bueno-López, José-L; Raio, Nicolas

    2015-03-01

    Translation facilitates transmission of knowledge between cultures. The fundamental transfer of anatomic terminology from the Ancient Greek and Islamic Golden Age cultures, to medieval Latin Christendom took place in the so-called Toledo School of Translators in the 12th-13th centuries. Translations made in Toledo circulated widely across Europe. They were the foundation of scientific thinking that was born in the boards of first universities. In Toledo, Gerard of Cremona translated Avicenna's Canon of Medicine, the key work of Islamic Golden Age of medicine. Albertus Magnus, Mondino de Luzzi and Guy de Chauliac, the leading authors of anatomical Latin words in the Middle Ages, founded their books on Gerard's translations. The anatomical terms of the Canon retain auctoritas up to the Renaissance. Thus, terms coined by Gerard such as diaphragm, orbit, pupil or sagittal remain relevant in the current official anatomical terminology. The aim of the present paper is to bring new attention to the highly significant influence that the Toledo School of Translators had in anatomical terminology. For this, we shall review here the onomastic origins of a number of anatomical terms (additamentum; coracoid process; coxal; false ribs; femur; panniculus; spondylus; squamous sutures; thorax; xiphoid process, etc.) which are still used today.

  1. East or west: to which subspecies does the type specimen of the Galah, Eolophus roseicapilla (Vieillot, 1817) (Aves: Cacatuidae), belong?

    PubMed

    Schodde, Richard; Black, Andrew B; Fornasiero, F Jean

    2016-01-01

    The Galah (Eolophus roseicapilla) is a pink-and-grey cockatoo, widespread in and endemic to Australia, and now familiar as a cage bird world-wide. It has three currently recognised subspecies: roseicapilla Vieillot, 1817 in the Australian west, kuhli Mathews, 1912 in the far north, and albiceps Schodde, 1989 in the east (Schodde 1997; Higgins 1999; Dickinson & Remsen 2013; del Hoyo & Collar 2014; Engelhard et al. 2015). The northern subspecies, kuhli, is not involved in the issue of type identity of roseicapilla, and so is not considered further here. First to distinguish east and west subspecies was G.M. Mathews (1912). Without explanation then or later, Mathews arbitrarily applied the senior specific name, Cacatua roseicapilla Vieillot, 1817 and its two objective synonyms based on the same type-eos Kuhl, 1820 and rosea Vieillot, 1822-to the eastern subspecies, and introduced the new name assimilis for the then supposedly undescribed western form. Mathews' lead was followed unquestioningly until the late 1980s when Schodde (1989) and Rowley (1990: 3) concluded that the type of Vieillot's roseicapilla was of the western subspecies, collected by the Baudin expedition in the region of Shark Bay on the mid-western Australian coast. Rowley (l.c.), but not Schodde (l.c.) contrary to Rowley's reference, went further to claim that it had been taken by François Péron in 1803, presumably on the brief return visit of Baudin in Le Géographe to Shark Bay en route to France. This left the eastern subspecies un-named, which Schodde (l.c.) accordingly described as albiceps. PMID:27395892

    An increasing proportion of the Earth's surface is illuminated at night. In aquatic ecosystems, artificial light at night (ALAN) may influence microbial communities living in the sediments. These communities are highly diverse and play an important role in the global carbon cycle. We combined field and laboratory experiments using sediments from an agricultural drainage system to examine how ALAN affects communities and alters carbon mineralization. Two identical light infrastructures were installed parallel to a drainage ditch before the start of the experiment. DNA metabarcoding indicated that both sediment communities were similar. After one was lit for five months (July-December 2012) we observed an increase in photoautotroph abundance (diatoms, Cyanobacteria) in ALAN-exposed sediments. In laboratory incubations mimicking summer and winter (six weeks each), communities in sediments that were exposed to ALAN for 1 year (July 2012-June 2013) showed less overall seasonal change compared with ALAN-naive sediments. Nocturnal community respiration was reduced in ALAN-exposed sediments. In long-term exposed summer-sediments, we observed a shift from negative to positive net ecosystem production. Our results indicate ALAN may alter sediment microbial communities over time, with implications for ecosystem-level functions. It may thus have the potential to transform inland waters to nocturnal carbon sinks. PMID:25780242

  4. ALUMINUM HYDRIDE: A REVERSIBLE MATERIAL FOR HYDROGEN STORAGE

    2008-12-31

    Hydrogen storage is one of the greatest challenges for implementing the ever sought hydrogen economy. Here we report a novel cycle to reversibly form high density hydrogen storage materials such as aluminium hydride. Aluminium hydride (AlH{sub 3}, alane) has a hydrogen storage capacity of 10.1 wt% H{sub 2}, 149 kg H{sub 2}/m{sup 3} volumetric density and can be discharged at low temperatures (< 100 C). However, alane has been precluded from use in hydrogen storage systems because of the lack of practical regeneration methods; the direct hydrogenation of aluminium to form AlH{sub 3} requires over 10{sup 5} bars of hydrogen pressure at room temperature and there are no cost effective synthetic means. Here we show an unprecedented reversible cycle to form alane electrochemically, using alkali alanates (e.g. NaAlH{sub 4}, LiAlH{sub 4}) in aprotic solvents. To complete the cycle, the starting alanates can be regenerated by direct hydrogenation of the dehydrided alane and the alkali hydride being the other compound formed in the electrochemical cell. The process of forming NaAlH{sub 4} from NaH and Al is well established in both solid state and solution reactions. The use of adducting Lewis bases is an essential part of this cycle, in the isolation of alane from the mixtures of the electrochemical cell. Alane is isolated as the triethylamine (TEA) adduct and converted to pure, unsolvated alane by heating under vacuum.

Here we show an unprecedented reversible cycle to form alane electrochemically, using alkali metal alanates (e.g. NaAlH{sub 4}, LiAlH{sub 4}) in aprotic solvents. To complete the cycle, the starting alanates can be regenerated by direct hydrogenation of the dehydrided alane and the alkali hydride being the other compound formed in the electrochemical cell. The process of forming NaAlH{sub 4} from NaH and Al is well established in both solid state and solution reactions. The use of adducting Lewis bases is an essential part of this cycle, in the isolation of alane from the mixtures of the electrochemical cell. Alane is isolated as the triethylamine (TEA) adduct and converted to pure, unsolvated alane by heating under vacuum.

    Obesity is a common disorder with many complications. Although chronodisruption plays a role in obesity, few epidemiological studies have investigated the association between artificial light at night (ALAN) and obesity. Since sleep health is related to both obesity and ALAN, we investigated the association between outdoor ALAN and obesity after adjusting for sleep health. We also investigated the association between outdoor ALAN and sleep health. This cross-sectional survey included 8526 adults, 39-70 years of age, who participated in the Korean Genome and Epidemiology Study. Outdoor ALAN data were obtained from satellite images provided by the US Defense Meteorological Satellite Program. We obtained individual data regarding outdoor ALAN; body mass index; depression; and sleep health including sleep duration, mid-sleep time, and insomnia; and other demographic data including age, sex, educational level, type of residential building, monthly household income, alcohol consumption, smoking status and consumption of caffeine or alcohol before sleep. A logistic regression model was used to investigate the association between outdoor ALAN and obesity. The prevalence of obesity differed significantly according to sex (women 47% versus men 39%, p < 0.001) and outdoor ALAN (high 55% versus low 40%, p < 0.001). Univariate logistic regression analysis revealed a significant association between high outdoor ALAN and obesity (odds ratio [OR] 1.24, 95% confidence interval [CI] 1.14-1.35, p < 0.001). Furthermore, multivariate logistic regression analyses showed that high outdoor ALAN was significantly associated with obesity after adjusting for age and sex (OR 1.25, 95% CI 1.14-1.37, p < 0.001) and even after controlling for various other confounding factors including age, sex, educational level, type of residential building, monthly household income, alcohol consumption, smoking, consumption of caffeine or alcohol before sleep, delayed sleep pattern, short sleep duration and

    Results of the radio OH emission from Comet Halley obtained with the 43-m NRAO telescope over the period from July 1985 to May 1986 show the global properties to be close to those predicted by Schloerb and Gerard (1985). The OH production rates are found to be well correlated with heliocentric magnitude estimates and to roughly follow the production rates determined from UV OH observations. After correction for the Greenstein effect, the mean velocities suggest that there is anisotropic outgassing of the parent molecule. An increase in the linewidths of the OH emission near and after perihelion is also noted.

Sagan, a student of Kuiper at the Yerkes Observatory, reflected a mindset that had become a missionary statement for planetary specialists and NASA programme managers. 'The subject was then considered by most professional astronomers to be at least slightly disreputable, tainted with Lowellian excesses', Sagan contended (1980, p. 143), referring to Percival Lowell's flamboyant claims about observing evidence of advanced civilisations on Mars at the turn of the century.

    The global VLBI observation started in the 1979. After that the qualities of the measurements are continuously improving by taking into account various instrumental and environmental effects. The MHB2000 models was introduced in 2002 (Mathews, et.al. 2002, [1]) and it has a good agreement (5 μas) on the short period nutation series (<400 days) with the values derived from 2 decades (1979-2000) VLBI data while a higher uncertainties up to 56 μas for those longer periods (>400 days) nutation series (Herring et.al. 2002). In MHB2000, the forcing frequencies of the nutation series are solved by least-squares fitting to the VLBI data in frequency domain. Koot et al. (2008), have processed another similar set of nutation series by inversing the time series of VLBI data (1984-2005) using a Bayesian approach. In the present work, we will repeat both approaches using the up-to-date 3.5 decades VLBI observations (1980-2014) meanwhile paying more attention on the results of longer period (>400 days). Finally some features of Earth's interior structure will be discussed based on the determined nutation series. [1] Mathews, P.M., Herring, T.A. & Buffett, B.A., 2002.

    The leafhopper genus Kabakra was established with Kabakra augusta from Vietnam as its type species by Dworakowska (1979). Later, another two species were described from India (Sohi & Mann 1992, Mathew & Ramakrishnan 1996). The genus was reviewed by Cao et al. (2012), who redescribed the genus and added three new species from China and Thailand. So far, six species have been reported, all from the Oriental region (see Dmitriev, 2016). In the present paper, two new species, K. chaiyaphuma and K. sakona spp. nov. are described and illustrated, with a key and a checklist to all known species of Kabakra. PMID:27394374

    2015-03-01

    In pursuit of more mindful notions of hybridity, this review essay provides a series of reflections on Mathew Weinstein's representations of Street Medics and `sciences for the red zones of neoliberalism'. My analysis draws on three popular ways of thinking with boundaries to offer a critical reading of the boundary-work that the essay performs with respect to three dialectics: (1) technical and political; (2) disciplinarily and multidisciplinarities; and (3) structures and agencies. I conclude with reflections on my boundary labour as a researcher, writer and pedagogue and how such cultural work might learn to live better with difference, ambiguities, hybrids and cross-hybrid learning.

    1997-07-01

    A dynamical and orbital analysis of micrometeors detected with the Arecibo 430 MHz radar (and some dual frequency with 50 MHz) has been carried out which includes radiation pressure as well as perturbations by Jupiter and Saturn. Since these objects are apparently a new class of micrometeoroid (Mathews et al., Icarus, 1997), accurate orbital analysis is essential to determine their origin. The hypothesis that all of these small, dense particles originated from outside the solar system is explored in some detail. Alternatives to this view are briefly considered and will be the subject of future dynamical investigations.

    2016-04-01

    A novel exactly solvable Schrödinger equation with a position-dependent mass (PDM) describing a Coulomb problem in D dimensions is obtained by extending the known duality relating the quantum d-dimensional oscillator and D-dimensional Coulomb problems in Euclidean spaces for D = (d+2)/2 . As an intermediate step, a mapping between a quantum d-dimensional nonlinear oscillator of Mathews-Lakshmanan type (or oscillator in a space of constant curvature) and a quantum D-dimensional Coulomb-like problem in a space of nonconstant curvature is derived. It is finally reinterpreted in a PDM background.

    Professor Mathew Bacon, MD of The Conclude Consultancy, argues that with healthcare facilities required to play a considerable part in helping the UK meet tough carbon reduction targets, a new approach to designing large acute hospitals is required that takes significantly greater account of such facilities' 'In-use' energy consumption. Equally, he believes, designing hospitals that meet lower carbon consumption goals requires greater dialogue between clinicians and engineers so that the resulting clearer perspective on clinical processes can be leveraged to inform the engineering design, and achieve 'a close coupling' between the engineering design strategy and the working practice needs of users.

    We present preliminary results of a test of competing scenarios for the formation of dusty optical filaments in the dominant galaxies at the centers of some cluster cooling flows. Two models are compared: the capture or disruption of gas-rich galaxies (Sparks, Ford & Kinney 1993) and the standard cooling flow condensate model (Mathews & Bregman 1978). The pros and cons of each model are discussed based on detailed morphological analysis of filaments and their possible association with galaxies in Abell 1795 and Abell 426.

  10. ‘Herbals she peruseth’: reading medicine in early modern England

    PubMed Central

    Leong, Elaine

    2014-01-01

    In 1631, Richard Brathwaite penned a conduct manual for ‘English Gentlewomen’. In Brathwaite's mind, the ideal English gentlewoman was not only chaste, modest and honourable but also an avid reader. In fact, Brathwaite specifically recommends English gentlewomen to first peruse herbals and then to deepen their medical knowledge via conference. Centred on the manuscript notebooks of two late seventeenth-century women, Margaret Boscawen (d. 1688) and Elizabeth Freke (1642–1714), this article explores women and ‘medical reading’ in early modern England. It first demonstrates that whilst both women consulted herbals by contemporary authors such as John Gerard and Nicholas Culpeper, their modes of reading could not be more different. Where Freke ruminated, digested and abstracted from Gerard's large tome, Boscawen made practical lists from Culpeper's The English Physitian. Secondly, the article shows that both supplemented their herbal reading with a range of other vernacular medical texts including printed medical recipe books, contemporary pharmacopoeia and surgical handbooks. Early modern English women's medical reading, I argue, was nuanced, sophisticated and diverse. Furthermore, I contend that well-informed readers like Boscawen and Freke made smart medical consumers and formidable negotiators in their medical encounters. PMID:25821333
