    KENNEDY SPACE CENTER, FL - Veteran cosmonaut Valery Ryumin greets his wife, STS-84 Mission Specialist Elena V. Kondakova, with some flowers after the Space Shuttle orbiter Atlantis lands on KSC's Runway 33. STS-84 was the sixth docking of the Space Shuttle with the Russian Space Station Mir. The nine-day STS-84 mission was Kondakova's second space flight, but her first on the Space Shuttle. She spent 169 days in space as flight engineer of the 17th main mission on Mir from October 1994 to March 1995. Her husband is now director of the Mir-Shuttle program for Russia.

  2. Variability of dissolved CO2 in the Pang and Lambourn Chalk rivers

    NASA Astrophysics Data System (ADS)

    Griffiths, J.; Nutter, J.; Binley, A.; Crook, N.; Young, A.; Pates, J.

    2007-01-01

    This paper presents the results of a two-year field campaign to determine the spatial and temporal variability of groundwater interaction with surface waters in two Cretaceous Chalk catchments (the Pang and Lambourn) in the Upper Thames in Berkshire, UK, based on measurement of dissolved carbon dioxide (CO2). Average stream water concentrations of dissolved CO2 were up to 35 times the concentration at atmospheric equilibrium. Mean groundwater concentrations of 85 and 70 times the atmospheric equilibrium were determined from borehole water sampled in the Pang and Lambourn respectively. Diurnal and seasonal variation of in-stream concentration of dissolved CO2 is not significant enough to mask the signal from groundwater inputs.

  8. VizieR Online Data Catalog: HST photometry of stars in HD 97950 (Pang+, 2016)

    NASA Astrophysics Data System (ADS)

    Pang, X.; Pasquali, A.; Grebel, E. K.

    2016-07-01

    The HD97950 cluster and its immediate surroundings in the giant HII region NGC3603 were observed with the Hubble Space Telescope (HST). The ultraviolet (UV) data were taken with the High Resolution Channel (HRC) of the Advanced Camera for Surveys (ACS) in 2005 (GO 10602, PI: Jesus Maiz Apellaniz) through the F220W, F250W, F330W, and F435W filters. The HRC is characterized by a spatial resolution of 0.03"/pixel and a field of view of 29''*25''. The optical observations were carried out with the Wide Field and Planetary Camera 2 (WFPC2) in two epochs: 1997 (GO 6763, PI: Laurent Drissen) and 2007 (GO 11193, PI: Wolfgang Brandner) through the F555W, F675W, and F814W filters. The Planetary Camera (PC) chip was centered on the cluster (0.045"/pixel, 40''*40'') for both programs. Pang et al. 2013 (cat. J/ApJ/764/73) reduced the two-epoch WFPC2 data and identified more than 400 member stars on the PC chip via relative proper motions. Of these member stars, 142 are in common between the HRC and PC images and thus have UV and optical photometry available (see Table1). Among the HD97950 cluster member stars determined from relative proper motions (Pang et al. 2013, cat. J/ApJ/764/73, Table2), there are five main-sequence (MS) stars located in the cluster with projected distances of r<0.7pc from the center, for which there are also spectral types available from Table3 of Melena et al. (2008AJ....135..878M). The photometry of these five MS stars is presented in Table2. The individual color excesses and extinctions of the member main sequence stars are listed in Table3. (3 data files).

  9. The initial break-up of Pangæa elicited by Late Palæozoic deglaciation

    PubMed Central

    Yeh, Meng-Wan; Shellnutt, J. Gregory

    2016-01-01

    The break-up of Pangæa was principally facilitated by tensional plate stress acting on pre-existing suture zones. The rifting of Pangæa began during the Early Permian along the southern Tethys margin and produced the lenticular-shaped continent known as Cimmeria. A mantle-plume model is ascribed to explain the rift-related volcanism but the NW-SE oriented Cimmerian rifts do not correlate well with pre-existing suture zones or ‘structural heterogeneities’ but appear to have a pertinent spatial and temporal association with Late Palæozoic glacial-interglacial cycles. Mantle potential temperature estimates of Cimmerian rift-related basalts (1410 °C ± 50 °C) are similar to ambient mantle conditions rather than an active mantle-plume rift as previously suggested. Moreover, we find that the distribution of glacial deposits shows significant temporal and spatial concurrence between the glacial retreat margins and rifting sites. We conclude that the location and timing of Cimmerian rifting resulted from the exploitation of structural heterogeneities within the crust that formed due to repeated glacial-interglacial cycles during the Late Palæozoic. Such effects of continental deglaciation helped to create the lenticular shape of Cimmeria and Neotethys Ocean suggesting that, in some instances, climate change may directly influence the location of rifting.

  13. Coumarin inhibits the growth of carrot (Daucus carota L. cv. Saint Valery) cells in suspension culture.

    PubMed

    Abenavoli, Maria Rosa; Sorgonà, Agostino; Sidari, Maria; Badiani, Maurizio; Fuggi, Amodio

    2003-03-01

    We used a carrot (Daucus carota L. cv. Saint Valery) cell suspension culture as a simplified model system to study the effects of the allelochemical compound coumarin (1,2 benzopyrone) on cell growth and utilisation of exogenous nitrate, ammonium and carbohydrates. Exposure to micromolar levels of coumarin caused severe inhibition of cell growth starting from the second day of culture onwards. At the same time, the presence of 50 mumol/L coumarin caused accumulation of free amino acids and of ammonium in the cultured cells, and stimulated their glutamine synthetase, glutamate dehydrogenase, glucose-6-phosphate dehydrogenase and phosphoenolpyruvate carboxylase activities. Malate dehydrogenase, on the other hand, was inhibited under the same conditions. These effects were interpreted in terms of the stimulation of protein catabolism and/or interference with protein biosynthesis induced by coumarin. This could have led to a series of compensatory changes in the activities of enzymes linking nitrogen and carbon metabolism. Because coumarin seemed to abolish the exponential phase and to accelerate the onset of the stationary phase of cell growth, we hypothesise that such allelochemical compounds may act in nature as an inhibitor of the cell cycle and/or as a senescence-promoting substance.

    Severin, Laura

    2015-01-01

    This article examines the poetic contribution of Valerie Gillies, Edinburgh Makar (or poet of the city) from 2005-2008, to the Edinburgh Marie Curie Hospice Quiet Room, a new contemplation space for patients, families, and staff. In collaboration with others, Gillies created a transitional space for the Quiet Room, centered on the display of her sonnet, "A Place Apart." This space functions to comfort visitors to the Quiet Room by relocating them in their surroundings and offering the solace provided by nature and history. With this project, her first as Edinburgh Makar, Gillies redefines the role of the poet as healer and advocates for newer forms of palliative care that focus on patients' spiritual and emotional, as well as physical, wellbeing.

    2012-01-01

    This paper examines the development and termination of nebacumab (Centoxin®), a human IgM monoclonal antibody (mAb) drug frequently cited as one of the notable failures of the early biopharmaceutical industry. The non-approval of Centoxin in the United States in 1992 generated major concerns at the time about the future viability of any mAb therapeutics. For Centocor, the biotechnology company that developed Centoxin, the drug posed formidable challenges in terms of safety, clinical efficacy, patient selection, the overall economic costs of health care, as well as financial backing. Indeed, Centocor's development of the drug brought it to the brink of bankruptcy. This article shows how many of the experiences learned with Centoxin paved the way for the current successes in therapeutic mAb development. PMID:22531443

    2004-01-01

    Emerging Themes in Epidemiology (ETE) is a new, online, Open Access peer-reviewed journal. The Journal is unique in that it was conceived and is managed by research degree students in epidemiology and related public health fields. The Journal's management is overseen by its Editor-in-Chief and Associate Faculty Editors, all of whom are senior members of faculty. ETE aims to encourage debate and discussion on the theoretical, methodological and practical aspects of epidemiologic research and practice. In addition, ETE is dedicated to the promotion of Open Access publication and the training of research students in the scientific publishing process. This editorial, to coincide with the launch of ETE, sets out the Journal's philosophy and aims. Epidemiology is a rich and innovative science that has much to gain from broader discussion of the causal frameworks that underpin it. ETE aims to be a major forum for such discussion. PMID:15679908

    Coffee is one of the most widely consumed beverages in the world and has a number of potential health benefits. Coffee may influence energy expenditure and energy intake, which in turn may affect body weight. However, the influence of coffee and its constituents - particularly caffeine - on appetite remains largely unexplored. The objective of this study was to examine the impact of coffee consumption (with and without caffeine) on appetite sensations, energy intake, gastric emptying, and plasma glucose between breakfast and lunch meals. In a double-blind, randomised crossover design. Participants (n = 12, 9 women; Mean ± SD age and BMI: 26.3 ± 6.3 y and 22.7 ± 2.2 kg•m⁻²) completed 4 trials: placebo (PLA), decaffeinated coffee (DECAF), caffeine (CAF), and caffeine with decaffeinated coffee (COF). Participants were given a standardised breakfast labelled with ¹³C-octanoic acid and 225 mL of treatment beverage and a capsule containing either caffeine or placebo. Two hours later, another 225 mL of the treatment beverage and capsule was administered. Four and a half hours after breakfast, participants were given access to an ad libitum meal for determination of energy intake. Between meals, participants provided exhaled breath samples for determination of gastric emptying; venous blood and appetite sensations. Energy intake was not significantly different between the trials (Means ± SD, p> 0.05; Placebo: 2118 ± 663 kJ; Decaf: 2128 ± 739 kJ; Caffeine: 2287 ± 649 kJ; Coffee: 2016 ± 750 kJ); Other than main effects of time (p <0.05), no significant differences were detected for appetite sensations or plasma glucose between treatments (p > 0.05). Gastric emptying was not significantly different across trials (p > 0.05). No significant effects of decaffeinated coffee, caffeine or their combination were detected. However, the consumption of caffeine and/or coffee for regulation of energy balance over longer periods of time warrant further investigation. PMID:25218717

    Many commentators believe that by the year 2000 fossil fuels will be gone and Americans will freeze to death - in the dark. But this essentially optimistic book puts the problems and the possibilities into clearer perspective. Written by Massachusetts Audubon Society scientists and editors and other concerned environmentalists, this book first presents the history of energy from wood through coal, oil, gas, nuclear, and solar. It examines the renaissance of solar energy - perhaps the prime source of energy for the future - whose foundations go back to 1600 when Western scientists used the sun to power engines. Commenting on the end of the fossil fuel era and the end of cheap energy, it considers bicycle power, wind energy, and hydro power. The book probes the pros and cons of nuclear power and presents the results of local action in one Massachusetts county. Two photo essays show the world of a fossil-fuel economy and an alternate landscape of a society fueled by renewable resources. 45 references.

  4. EDITORIAL: Special issue in honour of Professor Valery V Tuchin’s contribution to the field of biomedical optics

    2005-08-01

    This special issue of Journal of Physics D: Applied Physics covers some of the applied physics currently being addressed by light source researchers. Most of these papers originate from presentations made at the 10th International Symposium on the Science and Technology of Light Sources, held in Toulouse, France, on 18--22 July 2004. The conference attracted about 400 participants from all over the world. Abstracts of all papers, including extended abstracts of invited papers, were published in the conference book Light Sources 2004 (Institute of Physics Conference Series 182) edited by G Zissis. The full papers published in this issue reflect the wide-ranging nature of research on light sources. These collected full papers survived our rigorous journal review process and they report completed, previously unpublished, pieces of work. This is a research field that has seen many major contributions over the last hundred years; nevertheless it continues to produce new sources and important improvements to existing types. It is evident from these papers just how crucial are the materials used for light sources. Numerous recent lamp developments have depended critically on new or improved materials. Ten or more of the papers are concerned explicitly with materials: for example, an environmentally important and challenging area of research is to find a viable alternative to the use of mercury, particularly in fluorescent lamps. This is difficult because a substitute for Hg in general lighting must match the remarkable efficiency of Hg, or risk doing harm to the environment through increased energy consumption. Large-scale computation of the properties of both high- and low-pressure discharge lamps has become indispensable. A good example is in the paper by Derra et al, which is the first major review of an important lamp type. The lamp of interest is a mercury arc used in data projectors, operating with an arc gap of approximately 1 mm at more than 100 bar pressure. Most of the information needed for design is not accessible experimentally. Computer models were essential tools in many aspects of development, including finding out how the highly stressed materials could be used in ways that ensured acceptable life. Short-arc metal-halide lamps are used for producing white light in commercial premises, but they present numerous challenges to developers. Exceedingly complex chemistry, the many emitters and absorbers, the lack of symmetry, and the increasing influence of electrodes as the arc is shortened—all these pose many design problems that are being tackled with increasing success with the help of computer models. This special issue has many papers that deal with electrode issues, with special emphasis on the experimental verification of model predictions. Radiation transport also continues to be a major issue in constructing realistic discharge models. A number of papers tackle this in a simplified manner, whilst a new ray-tracing scheme offers hope of a realistic calculation of radiation in the complicated short-arc metal-halide lamps mentioned above. Light-emitting diodes are now having a major impact on some areas of lighting; two papers in this issue reflect that trend. The group of papers in this special issue will surely provide an important resource for those researching new and improved lamps.

    In order to clarify the impacts of southern rice black-streaked dwarf virus (SRBSDV) infection on rice plants, rice planthoppers and natural enemies, differences in nutrients and volatile secondary metabolites between infected and healthy rice plants were examined. Furthermore, the impacts of virus-mediated changes in plants on the population growth of non-vector brown planthopper (BPH), Nilaparvata lugens, and the selectivity and parasitic capability of planthopper egg parasitoid Anagrus nilaparvatae were studied. The results showed that rice plants had no significant changes in amino acid and soluble sugar contents after SRBSDV infection, and SRBSDV-infected plants had no significant effect on population growth of non-vector BPH. A. nilaparvatae preferred BPH eggs both in infected and healthy rice plants, and tended to parasitize eggs on infected plants, but it had no significant preference for infected plants or healthy plants. GC-MS analysis showed that tridecylic aldehyde occurred only in rice plants infected with SRBSDV, whereas octanal, undecane, methyl salicylate and hexadecane occurred only in healthy rice plants. However, in tests of behavioral responses to these five volatile substances using a Y-tube olfactometer, A. nilaparvatae did not show obvious selectivity between single volatile substances at different concentrations and liquid paraffin in the control group. The parasitic capability of A. nilaparvatae did not differ between SRBSDV-infected plants and healthy plant seedlings. The results suggested that SRBSDV-infected plants have no significant impacts on the non-vector planthopper and its egg parasitoid, A. nilaparvatae. PMID:25141278

  12. The theory of bio-energy transport in the protein molecules and its properties

    NASA Astrophysics Data System (ADS)

    Pang, Xiao-feng

    2011-10-01

    The bio-energy transport is a basic problem in life science and related to many biological processes. Therefore to establish the mechanism of bio-energy transport and its theory have an important significance. Based on different properties of structure of α-helical protein molecules some theories of bio-energy transport along the molecular chains have been proposed and established, where the energy is released by hydrolysis of adenosine triphosphate (ATP). A brief survey of past researches on different models and theories of bio-energy, including Davydov's, Takeno's, Yomosa's, Brown et al.'s, Schweitzer's, Cruzeiro-Hansson's, Forner's and Pang's models were first stated in this paper. Subsequently we studied and reviewed mainly and systematically the properties, thermal stability and lifetimes of the carriers (solitons) transporting the bio-energy at physiological temperature 300 K in Pang's and Davydov's theories. From these investigations we know that the carrier (soliton) of bio-energy transport in the α-helical protein molecules in Pang's model has a higher binding energy, higher thermal stability and larger lifetime at 300 K relative to those of Davydov's model, in which the lifetime of the new soliton at 300 K is enough large and belongs to the order of 10 -10 s or τ/τ⩾700. Thus we can conclude that the soliton in Pang's model is exactly the carrier of the bio-energy transport, Pang's theory is appropriate to α-helical protein molecules.

  3. [Exploring the changes of inheritance model of medical knowledge as viewed from the description of physicians in the Song Dynasty].

    PubMed

    Zhang, Haipeng

    2014-11-01

    From the Southern and Northern Dynasties to the beginning of the Northern Song Dynasty, the models of "master and apprentice" and "physician of long family tradition for generations" were the main ways for teaching medical knowledge. With the rapid amassment of medical books in the Song Dynasty, "reading text" became increasingly important and prominent in the inheritance of medical knowledge, which could be seen clearly from the descriptions on physicians in the Song Dynasty. For instance, Hao Yun's medical knowledge was recorded as a model of "master and apprentice" in Hao Yun's Epitaph written by Zhang Xun. However, in Ye Mengde's description, this model was played down, while at the same time, "reading text" was emphasized. Pang Anshi, though coming from a physician family for generations, got rid of some medical knowledge from his own family and turned to the medical knowledge by "reading text". According to Pang Anshi's Epitaph written by Zhang Lei and Fang ji Zhuan (Biography of Technicians) in Song shi (The Song History), Pang Anshi was a typical model of becoming a famous physician by "reading text". In the Epitaph, Pang Anshi's brilliance was stressed, and in the latter, "reading text" was more important and the family tradition was denied. In the description of the Song Dynasty, Chen Zhaoyu's wonderful medical skills was coming from the "practice", and "reading text" was denied right away. What is more, "reading text" was introspected and criticized through Chen Zhaoyu's lip. The different descriptions of the Song Dynasty reflected the change of inheritance model of medical knowledge.

    Marcel Proust endured severe allergies and bronchial asthma from early childhood. Those who suffer from the frightening and recurrent pangs of asthma often become dependent on their parents particularly mother; Proust was no exception. In his time asthma was poorly understood by physicians who considered the illness to be a type of hysteria. Decades later, we now understand that the severe, poorly controlled, suffocating episodes of asthma were responsible for the complex persona that Marcel Proust had assumed. PMID:10853866

    Polymeric cryogels are efficient carriers for the immobilization of biomolecules because of their unique macroporous structure, permeability, mechanical stability and different surface chemical functionalities. The aim of the study was to demonstrate the potential use of macroporous monolithic cryogels for biotoxin removal using anthrax toxin protective antigen (PA), the central cell-binding component of the anthrax exotoxins, and covalent immobilization of monoclonal antibodies. The affinity ligand (protein A) was chemically coupled to the reactive hydroxyl and epoxy-derivatized monolithic cryogels and the binding efficiencies of protein A, monoclonal antibodies to the cryogel column were determined. Our results show differences in the binding capacity of protein A as well as monoclonal antibodies to the cryogel adsorbents caused by ligand concentrations, physical properties and morphology of surface matrices. The cytotoxicity potential of the cryogels was determined by an in vitro viability assay using V79 lung fibroblast as a model cell and the results reveal that the cryogels are non-cytotoxic. Finally, the adsorptive capacities of PA from phosphate buffered saline (PBS) were evaluated towards a non-glycosylated, plant-derived human monoclonal antibody (PANG) and a glycosylated human monoclonal antibody (Valortim(®)), both of which were covalently attached via protein A immobilization. Optimal binding capacities of 108 and 117 mg/g of antibody to the adsorbent were observed for PANG attached poly(acrylamide-allyl glycidyl ether) [poly(AAm-AGE)] and Valortim(®) attached poly(AAm-AGE) cryogels, respectively, This indicated that glycosylation status of Valortim(®) antibody could significantly increase (8%) its binding capacity relative to the PANG antibody on poly(AAm-AGE)-protien-A column (p < 0.05). The amounts of PA which remained in the solution after passing PA spiked PBS through PANG or Valortim bound poly(AAm-AGE) cryogel were significantly (p < 0

  5. Exploring the variability in how educators attend to science classroom interactions

    NASA Astrophysics Data System (ADS)

    Gillespie, Colleen Elizabeth

    Many researchers assert educators must develop a shared instructional vision in order for schools to be effective. While this research tends to focus on educators' alignment around goals of science classrooms, I argue that we can't assume that educators agree on what they see when they look at science classrooms. In this dissertation, I explore the variability in what teachers and leaders notice in science classroom episodes and how they reason about what they notice. I ground my studies in real classroom practice: a videotaped lesson in the first study and a live classroom observation in the second. In Chapter 2, I discuss the importance of grounding discussions about teaching and learning in classroom artifacts, a commitment that motivates my dissertation: educators may have a shared vision when discussing teaching and learning in the abstract but disagree about whether that vision is being realized in a classroom. I then describe and analyze the video clip I used in my interviews, highlighting moments that I consider to be good teaching and learning. In Chapter 3, I present my first study, in which I showed this episode to 15 different science teachers, science instructional leaders, and principals. I found that participants attended to many different features in the episode, which led to significant disagreement about what is happening in the episode. Additionally, I found that these differences in attention corresponded to differences in how participants were framing the activity of watching the clip. In Chapter 4, I explore the attentional variability of one science instructional leader, Valerie, in multiple contexts. In addition to interviewing Valerie about the videotaped lesson, I also observed Valerie engage in an "observation cycle" with a teacher. Even though Valerie is quite skilled at attending to student thinking in some contexts, I found that Valerie's attention is strongly context-dependent and gets pulled away from students' scientific thinking

  6. Deblurring for spatial and temporal varying motion with optical computing

    2016-05-01

    A way to estimate and remove spatially and temporally varying motion blur is proposed, which is based on an optical computing system. The translation and rotation motion can be independently estimated from the joint transform correlator (JTC) system without iterative optimization. The inspiration comes from the fact that the JTC system is immune to rotation motion in a Cartesian coordinate system. The work scheme of the JTC system is designed to keep switching between the Cartesian coordinate system and polar coordinate system in different time intervals with the ping-pang handover. In the ping interval, the JTC system works in the Cartesian coordinate system to obtain a translation motion vector with optical computing speed. In the pang interval, the JTC system works in the polar coordinate system. The rotation motion is transformed to the translation motion through coordinate transformation. Then the rotation motion vector can also be obtained from JTC instantaneously. To deal with continuous spatially variant motion blur, submotion vectors based on the projective motion path blur model are proposed. The submotion vectors model is more effective and accurate at modeling spatially variant motion blur than conventional methods. The simulation and real experiment results demonstrate its overall effectiveness.

  1. Low LBNP tolerance in men is associated with attenuated activation of the renin-angiotensin system

    Greenleaf, J. E.; Petersen, T. W.; Gabrielsen, A.; Pump, B.; Bie, P.; Christensen, N. J.; Warberg, J.; Videbaek, R.; Simonson, S. R.; Norsk, P.

    Plasma vasoactive hormone concentrations [epinephrine (p(Epi)), norepinephrine (p(NE)), ANG II (p(ANG II)), vasopressin (p(VP)), endothelin-1 (p(ET-1))] and plasma renin activity (p(RA)) were measured periodically and compared during lower body negative pressure (LBNP) to test the hypothesis that responsiveness of the renin-angiotensin system, the latter being one of the most powerful vasoconstrictors in the body, is of major importance for LBNP tolerance. Healthy men on a controlled diet (2,822 cal/day, 2 mmol. kg(-1). day(-1) Na(+)) were exposed to 30 min of LBNP from -15 to -50 mmHg. LBNP was uneventful for seven men [25 +/- 2 yr, high-tolerance (HiTol) group], but eight men (26 +/- 3 yr) reached presyncope after 11 +/- 1 min [P < 0.001, low-tolerance (LoTol) group]. Mean arterial pressure (MAP) did not change measurably, but central venous pressure and left atrial diameter decreased similarly in both groups (5-6 mmHg, by approximately 30%, P < 0.05). Control (0 mmHg LBNP) hormone concentrations were similar between groups, however, p(RA) differed between them (LoTol 0.6 +/- 0.1, HiTol 1.2 +/- 0.1 ng ANG I. ml(-1). h(-1), P < 0.05). LBNP increased (P < 0. 05) p(RA) and p(ANG II), respectively, more in the HiTol group (9.9 +/- 2.2 ng ANG I. ml(-1). h(-1) and 58 +/- 12 pg/ml) than in LoTol subjects (4.3 +/- 0.9 ng ANG I. ml(-1). h(-1) and 28 +/- 6 pg/ml). In contrast, the increase in p(VP) was higher (P < 0.05) in the LoTol than in the HiTol group. The increases (P < 0.05) for p(NE) were nonsignificant between groups, and p(ET-1) remained unchanged. Thus there may be a causal relationship between attenuated activation of p(RA) and p(ANG II) and presyncope, with p(VP) being a possible cofactor. Measurement of resting p(RA) may be of predictive value for those with lower hypotensive tolerance.

    2015-01-01

    SUMMARY In spite of the crucial role of heterotrimeric G proteins as molecular switches transmitting signals from G protein-coupled receptors, their selective manipulation with small molecule, cell-permeable inhibitors still remains an unmet challenge. Here, we report that the small molecule BIM-46187, previously classified as pan-G protein inhibitor, preferentially silences Gαq signaling in a cellular context-dependent manner. Investigations into its mode of action reveal that BIM traps Gαq in the empty pocket conformation by permitting GDP exit but interdicting GTP entry, a molecular mechanism not yet assigned to any other small molecule Gα inhibitor to date. Our data show that Gα proteins may be “frozen” pharmacologically in an intermediate conformation along their activation pathway and propose a pharmacological strategy to specifically silence Gα subclasses with cell-permeable inhibitors.

    2016-07-01

    Pyogenic flexor tenosynovitis is an orthopedic emergency most commonly caused by Staphylococcus aureus and streptococci and occasionally, when associated with water exposure, Mycobacterium marinum. Shewanella algae, a gram-negative bacillus found in warm saltwater environments, has infrequently been reported to cause serious soft tissue infections and necrosis. In this case, S. algae caused complicated flexor tenosynovitis requiring open surgical irrigation and debridement. Flexor tenosynovitis caused by S. algae rapidly presented with all 4 Kanavel cardinal signs as well as subcutaneous purulence, ischemia, and necrosis, thus meeting the requirements for Pang et al group III classification of worst prognosis. Because of its rarity and virulence, S. algae should always be considered in cases of flexor tenosynovitis associated with traumatic water exposure to treat and minimize morbidity appropriately.

  4. Controls on the discharge of Chalk streams of the Berkshire Downs, UK.

    PubMed

    Bradford, Richard B

    2002-01-23

    The water quality and biological functioning of major UK rivers draining permeable basins cannot be fully understood without knowledge of the spatial and temporal controls on the aquifer-river system. In this paper, hydrogeological features of Chalk streams feeding the Thames, the focus of this special issue, are described. Large-scale features, such as line sinks along the Thames and major tributaries such as the Kennet, tend to determine the regional groundwater flow patterns in the Chalk aquifer, whereas the complex characteristics of the Chalk dominate the local spatial and temporal patterns of groundwater discharge to the tributaries draining the dip slopes. These different controls are described and illustrated by particular reference to the Lambourn (a sub-catchment of the Kennet) and Pang catchments. Various issues requiring further investigation are also highlighted. PMID:11846087

  5. Directional drill keys completion of South China Sea pipeline

    Callnon, D.; Weeks, K.

    1996-04-08

    Directional drilling laid dual 12-in. natural gas pipelines beneath a critical sea wall on Lantau Island, Hong Kong New Territories, to complete a 30-mile gas-pipeline crossing of the South China Sea. The project was part of Towngas Lantau construction for Hong Kong`s new Chek Lap Kok International Airport on the island. To avoid disturbing a newly installed sea wall at Ta Pang Po beach, NKK subcontracted parallel beach approaches to Cherrington Corp., Sacramento. Between July 11 and Aug. 2, 1995, Cherrington Corp. drilled and forward-reamed two, 20 in., 1,294-ft holes to pull back the twin pipelines. The project was completed during typhoon weather, high seas, strong currents, and logistical problems associated with operating in a remote uninhabited area.

    The theory of Lee and Pang (1987), who obtained solutions for soliton stars composed of zero-temperature fermions and bosons, is applied here to quark soliton stars. Model soliton stars based on a simple physical model of the proton are computed, and the properties of the solitons are discussed, including the important problem of the existence of a limiting mass and thus the possible formation of black holes of primordial origin. It is shown that there is a definite mass limit for ponderable soliton stars, so that during cooling a soliton star might reach a stage beyond which no equilibrium configuration exists and the soliton star probably will collapse to become a black hole. The radiation of ponderable soliton stars may alter the short-wavelength character of the cosmic background radiation, and may be observed as highly redshifted objects at z of about 100,000.

  7. Spinal Cord Injury without Radiographic Abnormality (SCIWORA) – Clinical and Radiological Aspects

    Szwedowski, Dawid; Walecki, Jerzy

    2014-01-01

    Summary The acronym SCIWORA (Spinal Cord Injury Without Radiographic Abnormality) was first developed and introduced by Pang and Wilberger who used it to define “clinical symptoms of traumatic myelopathy with no radiographic or computed tomographic features of spinal fracture or instability”. SCIWORA is a clinical-radiological condition that mostly affects children. SCIWORA lesions are found mainly in the cervical spine but can also be seen, although much less frequently, in the thoracic or lumbar spine. Based on reports from different authors, SCIWORA is responsible for 6 to 19% and 9% to 14% of spinal injuries in children and adults, respectively. Underlying degenerative changes, including spondylosis or spinal canal stenosis, are typically present in adult patients. The level of spinal cord injury corresponds to the location of these changes. With recent advances in neuroimaging techniques, especially in magnetic resonance imaging, and with increasing availability of MRI as a diagnostic tool, the overall detection rate of SCIWORA has significantly improved.

  8. Uncertainty estimates for the Bayes Inference Engine, (BIE)

    SciTech Connect

    Beery, Thomas A

    2009-01-01

    In the fall 2007 meeting of the BIB users group, two approaches to making uncertainty estimates were presented. Ken Hanson asserted that if the BFGS optimizer was used, the inverse Hessian matrix was the same as the covariance matrix representing parameter uncertainties. John Pang presented preliminary results of a Monte Carlo method called Randomized Maximum Likelihood (RML). The BFGS/Hessian matrix approach may be applied to the region of the 'ideal model' Approximately 250 parameters describing the object density patches that are varied to match an image of 1,000,000 pixels. I cast this in terms of least squares analysis, as it is much better understood. This not as large a conceptual jump as some suppose because many of the functional blocks in the BIB are taken directly from existing least squares programs. If a Gaussian (normal) probability density function is assumed for both the observation and parameter errors, the Bayesian and least squares result should be identical.

  9. Ambidextrous bend patterns in free-standing polar smectic- CPF films

    2008-12-01

    We report an unusual behavior of a ferroelectric smectic-CPF film formed by bent-shaped molecules. The ground state of the c -director in such film is not uniform but forms a striped pattern with alternating bend deformation. We found that the sense of the alternating bend is not related to an alternating handedness defined by the mutual orientation of the tilt ( c director) and the bow ( p director) of the molecules. Despite its similarity to a previously described twist-bend instability [J. Pang and N. A. Clark, Phys. Rev. Lett. 73, 2332 (1994)], this pattern cannot be explained in terms of spontaneous chiral symmetry breaking with continuous variation of the chirality order parameter, since the synclinic order of the polar molecules predefines the chirality of the film. We discuss possible models describing the spontaneous formation of an ambidextrous bend pattern of the c director.

    The flowers of twenty-three cultivars of Dendranthema grandiflorum Ramat. were investigated to determine anthocyanin and carotenoid levels and to confirm the effects of the pigments on the flower colors using high-performance liquid chromatography (HPLC) and electrospray ionization-mass spectrometry (ESI-MS). The cultivars contained the anthocyanins cyanidin 3-glucoside (C3g) and cyanidin 3-(3"-malonoyl) glucoside (C3mg) and the following carotenoids: lutein, zeaxanthin, β-cryptoxanthin, 13-cis-β-carotene, α-carotene, trans-β-carotene, and 9-cis-β-carotene. The cultivar "Magic" showed the greatest accumulation of total and individual anthocyanins, including C3g and C3gm. On the other hand, the highest level of lutein and zeaxanthin was noted in the cultivar "Il Weol". The cultivar "Anastasia" contained the highest amount of carotenoids such as trans-β-carotene, 9-cis-β-carotene, and 13-cis-β-carotene. The highest accumulation of β-cryptoxanthin and α-carotene was noted in the cultivar "Anastasia" and "Il Weol". Our results suggested that 'Magic", "Angel" and "Relance' had high amounts of anthocyanins and showed a wide range of red and purple colors in their petals, whereas "Il Weol', "Popcorn Ball' and "Anastasia" produced higher carotenoid contents and displayed yellow or green petal colors. Interestingly, "Green Pang Pang", which contained a high level of anthocyanins and a medium level of carotenoids, showed the deep green colored petals. "Kastelli", had high level of carotenoids as well as a medium level of anthocyanins and showed orange and red colored petals. It was concluded that each pigment is responsible for the petal's colors and the compositions of the pigments affect their flower colors and that the cultivars could be a good source for pharmaceutical, floriculture, and pigment industries.

    Vegetation variables like Gross Primary productivity (GPP) and the Normalized Difference Vegetation Index (NDVI) are key variables in vegetation carbon exchange studies. Field measurements of the NDVI are time consuming due to landscape heterogeneity across time. Typically a sampling protocol adopted during field campaigns is based on the VALERI protocol in that case toe estimate LAI. Field campaign GPP or NDVI measurements can be scaled up to using in-situ FLUXNET radiation raster maps. Regression analysis can then be applied to construct transfer functions for the determination of GPP raster maps raster imagery from Normalized Difference Vegetation Index (NDVI) raster maps derived from in-situ FLUXNET radiation raster maps. Subsequently, in the VALERI approach the scaling up of raster maps is performed by aggregation of high resolution in-situ FLUXNET radiation raster maps data into high resolution raster maps and subsequently aggregating these to 1x1 km MODIS NDVI raster maps by calculating average NDVI values for the low resolution data. The up-scaled 1x1 km pixels are then used to validate the MODIS GPP and NVI products. Hence up scaling based on in-situ FLUXNET radiation measurements are not a luxury for large and heterogeneous sites. Therefore this paper tackles the problem of up scaling using in-situ FLUXNET radiation measurements. Key Words: FLUXNET, GPP, Plant Functional Types, Up-scaling

    Directional gap probability or gap fraction is a basic parameter in the optical remote sensing modeling. Although some approaches have been proposed to estimate this gap probability from remotely sensed measurements, few efforts have been made to investigate the scaling effects of this parameter. This paper analyzes the scaling effect through aggregating the high-resolution directional gap probability (pixel size of 20 meters) estimated from leaf area index (LAI) images of VALERI database by means of Beer's law and introduces an extension of clumping index, Ĉ, to compensate the scaling bias. The results show that the scaling effect depends on both the surface heterogeneity and the nonlinearity degree of the retrieved function. Analytical expressions for the scaling bias of gap probability and Ĉ are established in function of the variance of LAI and the mean value of LAI in a coarse pixel. With the VALERI dataset, the study in this paper shows that relative scaling bias of gap probability increases with decreasing spatial resolution for most of land cover types. Large relative biases are found for most of crops sites and a mixed forest site due to their relative large variance of LAI, while very small biases occur over grassland and shrubs sites. As for Ĉ, it varies slowly in the pure forest, grassland and shrubs sites, while more significantly in crops and mixed forest.

  13. New method for detecting domain wall trapping and motion at a constriction in narrow ferromagnetic wires using perpendicular-current giant magnetoresistance

    NASA Astrophysics Data System (ADS)

    Zambano, Antonio Javier

    improbable. With this technique, the position of the wall inside the notch region can be precisely determined. While H is swept, a wall trapped in a constriction moves between different points in the notch seeking a lower energy state, and it does not have to leave the constriction when the system is relaxed by sweeping the field to 0 Oe. When H is kept fixed, time dependence of wall position inside a U-shaped constriction in the thinner Py layer appears to be thermally activated at 4.2 K. No wall motion was observed in a V-shaped notch under the same circumstances. Along with these results, data from other studies, such as domain wall stability and effects of a high-density CPP current, are presented in this thesis to confirm the success and effectiveness of our technique. 1T.

    The purpose of this study was to develop a soap opera video, A Story about Toni, Mike, and Valerie, designed to communicate HIV risk reduction themes. The study evaluated viewing the video and responding to audio computer assisted self-interview (ACASI) on a handheld computer. The sample was 76 predominately African American women, aged 18-29, in sexual relationships with men. Data were collected in urban neighborhoods in the northeastern United States. A pretest-posttest control group design with systematic assignment indicated statistically significant reduction in expectations to engage in unprotected sex in the experimental group. The handheld computer was found to be acceptable to view the near feature length video and complete ACASI. To date, no study has reported on use of video and ACASI on a handheld device to reduce HIV risk. The significance is the potential to stream health promotion videos to personal devices, such as cell phones. PMID:18535900

    The Chalk is the largest aquifer in the UK accounting for more than half the groundwater used and nearly a quarter of the total public water supplied in England and Wales. Although the Chalk is a double porosity and permeability medium, transmission of water in the saturated zone depends largely on flow through fractures, the location and distribution of which are controlled by lithology and geological structure. These features operate on a number of spatial scales and so provide a range of flow pathways that can markedly affect both stream flow and water quality. In addition, overlying Palaeogene or superficial deposits can act as controls on recharge and zones of increased groundwater storage. As part of a major initiative on Lowland Catchment Research in the UK two Chalk sub-catchments, in the River Thames basin, the rivers Pang and Lambourn, have been the focus of an intensive set of studies. The catchments have been characterised using a multidisciplinary approach. This has resulted in an improved understanding of the way such catchments work and the mechanisms that control groundwater flow. The low fracture porosity gives rise to a low specific yield, which means that large fluctuations in water table elevation beneath the interfluves are not uncommon. Consequently, groundwater catchments differ from the topographic catchments and their size varies seasonally. This means, for example, that groundwater might be flowing to the River Pang in winter but to the River Thames in summer. It also means that various flow features in the catchment may be active at different locations and times during the year. Four flow systems have been identified, through a detailed analysis of the data; a shallow, but rapid flow system; a slower, deeper system; a very high velocity system developed in large diameter solution enhanced fractures and a system found in the river valley sediments. The interconnections between and within these systems can be poor and sometimes vary on a

    The purpose of this randomized, cross-over design study was to examine the effect of three different muscle potentiation protocols on acute changes in muscle architecture and vertical jump performance. Eleven experienced, resistance trained men (25.2±3.6y) completed three potentiation squat protocols using moderate intensity (MI; 75%, 3 sets x 10 repetitions), high intensity (HI; 90%, 3 sets x 3 repetitions) and 100% (1RM; 1 set x 1repetition) of their 1RM. In addition, all participants completed a control session (CTL) in which no protocol was performed. During each testing session, muscle architecture and vertical jump testing were assessed at baseline (BL), 8min post (8P) and 20min post (20P) workout. Ultrasound measures included cross sectional area (CSA) and pennation angle (PANG) of both the rectus femoris (RF) and vastus lateralis (VL). Following each ultrasound measure, peak vertical jump power (PVJP) and mean (MVJP) power was assessed using an accelerometer. Magnitude based inferences were used to make comparisons between trials. The MI trial resulted in a likely greater increase from BL to 8P and 20P in RF-CSA and VL-CSA, while the HI trial resulted in a likely greater change from BL to 20P in both RF-CSA and VL-CSA. Meanwhile, changes in PVJP and MVJP for the MI trial was likely decreased at BL-8P and BL–20P, while the HI trial was shown to result in a likely or possible decrease compared to CTL at BL-8P and BL–20P, respectively. A likely negative relationship was observed between changes in VL-PANG and MVJP (r = -0.35; p , 0.018) at BL-8P, and between changes in PVJP and RF-CSA (r = -0.37; p , 0.014) at BL–20P. Results of this study were unable to demonstrate any potentiation response from the trials employed, however these protocols did result in acute muscle architectural changes.

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

    The inclusion of fermions into simulations of lattice gauge theories is very difficult both theoretically and numerically. With the presence of Teraflops-scale computers for lattice gauge theory, the authors wanted a forum to discuss new approaches to lattice fermions. The workshop concentrated on approaches which are ripe for study on such large machines. Although lattice chiral fermions are vitally important to understand, there is not technique at hand which is viable on these Teraflops-scale machines for real-world problems. The discussion was therefore focused on recent developments and future prospects for QCD-like theories. For the well-known fermion formulations, the Aoki phase in Wilson fermions, novelties of U{sub A}(1) symmetry and the {eta}{prime} for staggered fermions and new approaches for simulating the determinant for Wilson fermions were discussed. The newer domain-wall fermion formulation was reviewed, with numerical results given by many speakers. The fermion proposal of Friedberg, Lee and Pang was introduced. They also were able to compare and contrast the dependence of QCD and QCD-like SUSY theories on the number of quark flavors. These proceedings consist of several transparencies and a summary page from each speaker. This should serve to outline the major points made in each talk.

    In the new injection scenario antiprotons are injected onto a helical orbit in the Tevatron in order to avoid the detrimental effects of the beam-beam interaction at 150 GeV. The new scenario required changes in the tuning procedure. Antiprotons are too precious to be used for tuning, therefore the antiproton injection line has to be tuned with protons by reverse injecting them from the Tevatron into the Main Pang (MR). Previously, the reverse injection was performed in one supercycle. One batch of uncoalesced bunches was injected into the Tevatron and ejected after 40 seconds. Then the orbit closure was performed in the MR. In the new scheme the lambertson magnets have to be moved and separator polarities have to be switched, activities that cannot be completed in one supercycle. Therefore, the reverse injection sequence was changed. This involved the redefinition of TVBS dock event $D8 as MRBS $D8 thus marking it possible to inject 6 proton batches and eject them one at a time on command, performing orbit closure each time in the MR.

    The considered evaluation shows that the revised quenching rate of O(1D) by N2 in the thermosphere derived from the data of Hays et al. (1978) is k(N2) = 2.3 x 10 to the -11th cc/s, in excellent agreement with the laboratory results of Streit et al. (1976). The laboratory measurements of the O(1D) and O(1S) transition coefficients by Kernahan and Pang (1975) are consistent with the aeronomic results of Frederick et al. (1976), Kopp et al. (1977), Hays et al. (1978), and Rusch et al. (1978) and are in agreement with the theoretical calculations. The revised value of J(O2) = 1.5 x 10 to the -6th per s is in agreement with the observations of Heroux and Swirbalus (1976). The specific recombination rate of O2(+) leading to the production of O(1D) is alpha(1D) = 2.1 x 10 to the -7th cc/s at ionospheric electron temperatures, in good agreement with the laboratory measurement by Zipf (1970).

    Maintaining and improving household food self-sufficiency (FSS) in mountain regions is an ongoing challenge. There are many facets to the issue, including comparatively high levels of land fragmentation, challenging terrain and transportation bottlenecks, declining labor availability due to out-migration, and low technical knowledge, among others. Using a nonparametric multivariate approach, we quantified primary associations underlying current levels of FSS in the mid-hills of Nepal. A needs assessment survey was administered to 77 households in Lungaun (Baglung District), Pang (Parbat District), and Pathlekhet (Myagdi District), with a total of 80 variables covering five performance areas; resulting data were analyzed using Classification and Regression Trees. The most parsimonious statistical model for household FSS highlighted associations with agronomic management, including yields of maize and fingermillet within a relay cropping system and adoption of improved crop cultivars. Secondary analyses of the variables retained in the first model again focused primarily on crop and livestock management. It thus appears that continued emphasis on technical agricultural improvements is warranted, independent of factors such as land holding size that, in any case, are very difficult to change through development interventions. Initiatives to increase household FSS in the mid-hills of Nepal will benefit from placing a primary focus on methods of agricultural intensification to improve crop yields and effective technology transfer to increase adoption of these methods.

    It is widely recognized that cascade models are potentially effective and powerful tools for interpreting and predicting multi-particle observables in heavy ion physics. However, the lack of common standards, documentation, version control, and accessibility have made it difficult to apply objective scientific criteria for evaluating the many physical and algorithmic assumptions or even to reproduce some published results. The first RIKEN Research Center workshop was proposed by Yang Pang to address this problem by establishing open standards for original codes for applications to nuclear collisions at RHIC energies. The aim of this first workshop is: (1) to prepare a WWW depository site for original source codes and detailed documentation with examples; (2) to develop and perform standardized test for the models such as Lorentz invariance, kinetic theory comparisons, and thermodynamic simulations; (3) to publish a compilation of results of the above work in a journal e.g., ``Heavy Ion Physics``; and (4) to establish a policy statement on a set of minimal requirements for inclusion in the OSCAR-WWW depository.

    Study of the small DNA tumor viruses continues to provide valuable new insights into oncogenesis and fundamental biological processes. While much has already been revealed about how the human papillomaviruses (HPVs) can transform cells and contribute to cervical and oropharyngeal cancer, there clearly is much more to learn. In this issue of Oncogene, Pang et al. demonstrate that the high-risk HPV16 E7 oncogene can promote cellular proliferation by interacting with the DREAM (DP, RB-like, E2F and MuvB) complex at two distinct phases of the cell cycle (1). Consistent with earlier work, HPV16 E7 can bind to the retinoblastoma tumor suppressor (RB) family member p130 (RBL2) protein and promote its proteasome-mediated destruction thereby disrupting the DREAM complex and prevent exit from the cell cycle into quiescence. In addition, they demonstrate that HPV16 E7 can bind to MuvB core complex in association with BMYB and FOXM1 and activate gene expression during the G2 and M phase of the cell cycle. Thus, HPV16 E7 acts to prevent exit from the cell cycle entry and promotes mitotic proliferation and may account for the high levels of FOXM1 often observed in poor risk cervical cancers.

  8. Suppressing technical noise in weak measurements by entanglement

    2015-07-01

    Postselected weak measurement has aroused broad interest for its distinctive ability to amplify small physical quantities. However, the low postselection efficiency to obtain a large weak value has been a big obstacle to its application in practice since it may waste resources, and reduce the measurement precision. An improved protocol was proposed in Pang et al., Phys. Rev. Lett. 113, 030401 (2014), 10.1103/PhysRevLett.113.030401 to make the postselected weak measurement dramatically more efficient by using entanglement. Such a protocol can increase the Fisher information of the measurement to approximately saturate the well-known Heisenberg limit. In this paper, we review the entanglement-assisted protocol of postselected weak measurement in detail, and study its robustness against technical noises. We focus on readout errors. Readout errors can greatly degrade the performance of postselected weak measurement, especially when the readout error probability is comparable to the postselection probability. We show that entanglement can significantly reduce the two main detrimental effects of readout errors: inaccuracy in the measurement result and the loss of Fisher information. We extend the protocol by introducing a majority vote scheme to postselection to further compensate for readout errors. With a proper threshold, almost no Fisher information will be lost. These results demonstrate the effectiveness of entanglement in protecting postselected weak measurement against readout errors.

    Oriental Beauty, which is made from tea leaves infested by the tea green leafhopper (Jacobiasca formosana) in Taiwan, has a unique aroma like ripe fruits and honey. To determine what occurs in the tea leaves during the oolong tea manufacturing process, the gene expression profiles and the chemical profiles were investigated. Tea samples were prepared from Camellia sinensis var. sinensis cv. Chin-shin Dah-pang while the tea leaves were attacked by the insect. The main volatile compounds, such as linalool-oxides, benzyl alcohol, 2-phenylethanol, and 2,6-dimethylocta-3,7-diene-2,6-diol, increased during manufacture. The gene expression profiles during manufacture were analyzed by differential screening between fresh leaves and tea leaves of the first turn over. Many up-regulated transcripts were found to encode various proteins homologous to stress response proteins. Accordingly, the endogenous contents of abscisic acid and raffinose increased during manufacture. Thus the traditional manufacturing method is a unique process that utilizes plant defense responses to elevate the production of volatile compounds and other metabolites. PMID:17587678

  10. A clear case for conscience in healthcare practice.

    2012-01-01

    The value of conscience in healthcare ethics is widely debated. While some sources present it as an unquestionably positive attribute, others question both the veracity of its decisions and the effect of conscientious objection on patient access to health care. This paper argues that the right to object conscientiously should be broadened, subject to certain previsos, as there are many benefits to healthcare practice in the development of the consciences of practitioners. While effects such as the preservation of moral integrity are widely considered to benefit practitioners, this paper draws on the work of Hannah Arendt to offer several original arguments in defence of conscience that may more directly benefit patients, namely that a pang of conscience may be useful in rapidly unfolding situations in which there is no time to reflect satisfactorily upon activities and that, given the hierarchical nature of healthcare institutions, a right to defy authority on the basis of conscience may benefit junior staff who lack the institutional power to challenge the orders of superiors.

    The East Georges Bank Basin is located offshore Nova Scotia on the southeastern Canadian continental shelf. The basin covers 2.5 million ac and is one of the last undrilled basins in North America. The geological interpretation is almost entirely based on 16,000 km of seismic data over the basin. Pertinent well control is limited to 10 wells on the US portion of the Georges Bank (West Georges Bank Basin) and two wells on the Scotian shelf. Seismic-stratigraphic analysis of this data has led to a structural and stratigraphic model for the basin. The basin formed during the Triassic when the landmass of Pange began separating along rift zones. A prominent Paleozoic basement high, the Yarmouth Arch separated the East Georges Bank Basin from the West Georges Bank Basin and had a dominant influence on sedimentation until the Middle Jurassic. Early synrift sequences consist of lacustrine clastics and shales. Marine incursions began in the late Triassic resulting in massive salt deposits that reflect the restricted extent of the basin and the arid Triassic and Early Jurassic climate. Further continental separation during the Early Jurassic resulted in deposition of carbonates and evaporites followed by Middle Jurassic continental shelf carbonates and deltaic sands. During the Middle Jurassic, major growth faulting and halokinesis was initiated by progradation of the deltaic sands. Post Middle Jurassic continental spreading in combination with changing climatic conditions resulted in a steady decline of carbonate sedimentation and dominance of clastic deposition throughout the remaining history of the basin.

  12. The mechanism and properties of bio-photon emission and absorption in protein molecules in living systems

    2012-05-01

    The mechanism and properties of bio-photon emission and absorption in bio-tissues were studied using Pang's theory of bio-energy transport, in which the energy spectra of protein molecules are obtained from the discrete dynamic equation. From the energy spectra, it was determined that the protein molecules could both radiate and absorb bio-photons with wavelengths of <3 μm and 5-7 μm, consistent with the energy level transitions of the excitons. These results were consistent with the experimental data; this consisted of infrared absorption data from collagen, bovine serum albumin, the protein-like molecule acetanilide, plasma, and a person's finger, and the laser-Raman spectra of acidity I-type collagen in the lungs of a mouse, and metabolically active Escherichia coli. We further elucidated the mechanism responsible for the non-thermal biological effects produced by the infrared light absorbed by the bio-tissues, using the above results. No temperature rise was observed; instead, the absorbed infrared light promoted the vibrations of amides as well the transport of the bio-energy from one place to other in the protein molecules, which changed their conformations. These experimental results, therefore, not only confirmed the validity of the mechanism of bio-photon emission, and the newly developed theory of bio-energy transport mentioned above, but also explained the mechanism and properties of the non-thermal biological effects produced by the absorption of infrared light by the living systems.

    Egg parasitoids of the genus Trichogramma are natural enemies of many lepidopteran borers in agricultural areas around the world. It is important to identify the correct species and ideally focus on endemic Trichogramma for pest control in particular crops. In this study, Trichogramma wasps were collected from parasitized eggs of Asian corn borer in Southwestern Taiwan. Three Trichogramma species, Trichogramma ostriniae Pang and Chen, Trichogramma chilonis Ishii, and T. sp. y, were identified based on morphology and the nucleotide sequence of the internal transcribed spacer 2 (ITS-2) region of rDNA. Although T. ostriniae and T. sp. y appear to be morphologically similar, ITS-2 identity between these two taxa is only 89%. Surprisingly, a commercially released Trichogramma colony thought to be T. chilonis possessed 99% identity (ITS-2) with the field T. sp. y individuals. This suggests past contamination leading to subsitution of the laboratory-reared T. chilonis colony by T. sp. y. Natural populations of all three Trichogramma species were found to be infected by a single Wolbachia strain which was identified using a wsp gene sequence. PMID:26896674

    The ancient book "Mozi" (5th century BC) records: "In ancient times, the San Miao tribes were in disarray. The sun rose in the evening...King Yu vanquished them. "King Yu is a prehistoric person living in 23-19th century BC. The strange phenomena "sun rose in evening" was explained as a large solar eclipse at sunset by Pang. Therefore investigations on it may lead to an important progress of Chinese chronology. After an analysis on all similar records in Chinese history, we pay main attention to the relationship of eclipse computations with parameter "c", the long term of earth's rotation rate. We have computed all the solar eclipses in that period by the way similar to that used for investigating the "double dawn" eclipse. By change parameter "c" in reasonable range (28-36 sec/cy2), we have found 11 possible results listed in a table. One figure shows the eclipse maps and relative "double dawn/dusk" areas while another one illustrates how the parameter "c" affects the result. For an exact conclusion of King Yu's chronology, we need further progress from both side: history which may limit the King Yu's period and astronomy which may limit the possible range of parameter "c".

    Background: Treatment of low-pressure hydrocephalus (LPH) may require prolonged external ventricular drainage (EVD) at sub-zero pressures to reverse ventriculomegaly. Endoscopic third ventriculostomy (ETV) has been used in the treatment of noncommunicating hydrocephalus; however, indications for ETV are expanding. Methods: Patients with the diagnosis of LPH as defined by the Pang and Altschuler criteria who underwent sub-zero drainage treatment over an 8-year period were included. Patients were divided into two cohorts based on whether or not ETV was employed during their treatment. Time from EVD placement to internalization of shunt was recorded for both groups; time from ETV to placement of shunt was recorded for the patients undergoing ETV. Results: Sixteen adult patients with LPH were managed with sub-zero drainage method. Ten (62.5%) patients did not undergo ETV and the average time from first ventriculostomy to shunting was 73 days (range 14–257 days). Six (37.5%) patients underwent ETV during the course of their treatment; average time from initial ventriculostomy to shunt was 114 days (range 0–236 days) (P = 0.16). Time from development of LPH to ETV ranged from 28 days to 6.5 months. In the ETV group, of the 4 patients who underwent shunting, the average time to shunting following ETV was 15.25 days. Conclusions: ETV can be used successfully in the management of refractory LPH to decrease the duration of EVD. PMID:27069743

  17. The ethics and regulation of overcharging: issues in the commerciality of the health practitioner-patient relationship.

    Overcharging by health practitioners is a difficult issue with few guidelines available for practitioners or patients. For the most part it has not been the subject of disciplinary censure and has been dealt with by conciliation processes. However, during 2013 the Singapore High Court twice addressed the commerciality of the health-practitioner-patient relationship, acknowledging that this is a fundamental attribute of the contemporary dynamic between providers and recipients of health services. In Lim Mey Lee Susan v Singapore Medical Council [2013] SGHC 122, it concluded that the obligation to refrain from overcharging is an inherent ethical responsibility of practitioners and affirmed the suspension for three years of a surgeon with Australian training and tertiary connections for what it classified as grossly excessive charging. In Pang Ah San v Singapore Medical Council [2013] SGHC 266, it observed that medical practitioners have a legitimate right to appropriate levels of remuneration but that the right balance has to be struck between professional virtues and business considerations. The Singapore High Court's decisions raise the question of whether professional associations and practitioner regulators have a responsibility to provide guidelines and, potentially, processes by which practical assistance can be provided to medical and other health care practitioners so that they can avoid unacceptable charging practices.

    Maintaining and improving household food self-sufficiency (FSS) in mountain regions is an ongoing challenge. There are many facets to the issue, including comparatively high levels of land fragmentation, challenging terrain and transportation bottlenecks, declining labor availability due to out-migration, and low technical knowledge, among others. Using a nonparametric multivariate approach, we quantified primary associations underlying current levels of FSS in the mid-hills of Nepal. A needs assessment survey was administered to 77 households in Lungaun (Baglung District), Pang (Parbat District), and Pathlekhet (Myagdi District), with a total of 80 variables covering five performance areas; resulting data were analyzed using Classification and Regression Trees. The most parsimonious statistical model for household FSS highlighted associations with agronomic management, including yields of maize and fingermillet within a relay cropping system and adoption of improved crop cultivars. Secondary analyses of the variables retained in the first model again focused primarily on crop and livestock management. It thus appears that continued emphasis on technical agricultural improvements is warranted, independent of factors such as land holding size that, in any case, are very difficult to change through development interventions. Initiatives to increase household FSS in the mid-hills of Nepal will benefit from placing a primary focus on methods of agricultural intensification to improve crop yields and effective technology transfer to increase adoption of these methods.

    A set of global optical potential parameters describing the A =3 particles (3He and 3H ) elastic scattering from 1 p -shell nuclei, HT 1 p , is obtained by simultaneously fitting 118 sets of experimental data of 3He and 3H elastic scattering from 9Be,10B ,11B ,12C ,13C ,14C ,14N ,15N ,16O ,17O , and 18O with incident energies from 4 ≤E ≤118.5 MeV and 24 sets of elastic scattering data with the 6Li and 7Li targets from 3 ≤E ≤44 MeV. HT 1 p is found to be superior to GDP08 [D. Y. Pang, P. Roussel-Chomaz, H. Savajols, R. L. Varner, and R. Wolski, Phys. Rev. C 79, 024615 (2009), 10.1103/PhysRevC.79.024615], which is a systematic potential designed for the heavy-target region, in the reproduction of the angular distributions of elastic scattering cross sections of 3He and 3H from 1 p -shell nuclei at energies below 100 MeV. At energies above 100 MeV, GDP08 is found to be better than HT1p.

    In the present work, a family of Calabi-Yau manifolds with a local Hamiltonian Killing vector is described in terms of a nonlinear equation whose solutions determine the local form of the geometries. The main assumptions are that the complex (3, 0)-form is of the form e{sup ik{Psi}}, where {Psi} is preserved by the Killing vector, and that the space of the orbits of the Killing vector is, for fixed value of the momentum map coordinate, a complex 4-manifold, in such a way that the complex structure of the 4-manifold is part of the complex structure of the complex 3-fold. The family considered here include the ones considered in A. Fayyazuddin, Classical Quantum Gravity 24, 3151 (2007); O. P. Santillan, Classical Quantum Gravity 27, 155013 (2010); H. Lu, Y. Pang, and Z. Wang, Classical Quantum Gravity 27, 155018 (2010) as a particular case. We also present an explicit example with holonomy exactly SU(3) by use of the linearization introduced in A. Fayyazuddin, Classical Quantum Gravity 24, 3151 (2007), which was considered in the context of D6 branes wrapping a complex 1-cycle in a hyperkahler 2-fold.

    The structure of nontopological solutions of Einstein field equations as proposed by Friedberg, Lee, and Pang (1987) is examined. This analysis incorporates finite temperature effects and pair creation. Quarks are assumed to be the only species that exist in interior of soliton stars. The possibility of primordial creation of soliton stars in the incomplete decay of the degenerate vacuum in early universe is explored. Because of dominance of pair creation inside soliton stars, the luminosity of soliton stars is not determined by its radiative transfer characteristics, and the surface temperature of soliton stars can be the same as its interior temperature. It is possible that soliton stars are intense X-ray radiators at large distances. Soliton stars are nearly 100 percent efficient energy converters, converting the rest energy of baryons entering the interior into radiation. It is possible that a sizable number of baryons may also be trapped inside soliton stars during early epochs of the universe. In addition, if soliton stars exist they could assume the role played by massive black holes in galactic centers.

    Hordes of tourists flock to Washington, D.C. every spring to see the cherry trees blossom. Once in the city, they must find their way to the Tidal Basin where the Japanese trees grow. Fortunately, a number of visual landmarks can help them to navigate. In 1910, the United States Congress passed The Height of Buildings Act, limiting the elevation of commercial and residential structures in D.C. to 130 feet. Thus, the 555-foot-tall Washington Monument often looms large against the horizon, serving as an anchor point to help set the tourists' sense of direction. Once their heading is set, they can lose sight of the monument behind buildings or groups of tall Scandinavian visitors and still use their internal compass to navigate to the Basin. This compass keeps track of their paces and turns and updates their sense of where they are and where they need to go. Yet while their heading informs their actions, it does not dictate them. Tourists who have been to D.C. in the past can, for example, use remembered views to alter their routes to avoid crowds. On an even finer scale, their leg movements also depend on their current state - they might increase the frequency and length of their strides if hunger pangs compete with their desire to see cherry blossoms, for example. The way in which these disparate cues and motivations influence exploration is a neuroscience mystery across creatures large and small. PMID:27269718

    For the treatment of refractory ascites we use the saphenoperitoneal shunt described by Pang in 1992 approximately 2 years. This procedure eliminates the most frequent complications of the former synthetic shunts: occlusion of the collector branches and infections as well. In addition, the use of autologous vein is cost-saving. The first Hungarian publications (K. Vincze and Z. Nagy et al.) reported good results, which are confirmed also by us, after we performed 21 operations. The publications until now usually describe the technique. This intervention is now a widely accepted one. On the other hand, just a small number of papers describe the options for the examination of patency and the follow-ups. We report about the algorithm used in our department after surgery to evaluate graft patency and surgical efficacy. A method to determine the volume of ascites developed by ourselves is described. We feel that the successful application of saphenoperitoneal shunts depends on very close follow-up. Considering that no objective method to check the patency does exist, we are sure that decisions about further operations can only be made if simultaneous diverse follow-up methods are available.

    The growing prevalence of autism spectrum disorder is accompanied by ongoing efforts to understand and support parents in the face of challenges related to their child's autism spectrum disorder. Although fathers are increasingly hands-on in raising children, research focus on parenting children with autism spectrum disorder continues to be skewed toward experiences of mothers. Our purpose in this article is to contribute understandings of how fathers of children with autism spectrum disorder perceive themselves to be managing, and we undertake this by examining comparisons fathers of children with autism spectrum disorder make between their parenting experiences and experiences of fathers of typically developing children. A purposive sample of 28 fathers of children (aged 2-13 years) with autism spectrum disorder living in an urban center in Western Canada participated in in-depth interviews about their parenting successes and challenges. We found fathers speak of universal fathering experiences yet articulate their own sense of loss and efforts to come to terms with unanticipated demands associated with autism spectrum disorder. Fathers of children with autism spectrum disorder feel "pangs of jealousy" toward fathers of typically developing children, yet they are keenly attentive to their own child's development and convey a sense of gratitude for their child's capabilities and personality amidst an appreciation for trials and triumphs of fathering in general and fathering a child with autism spectrum disorder in particular.

    2003-12-01

    In support of the NASA Earth Observing System (EOS) Land Product Validation investigations, numerous remotely sensed data and field measurements are being collected at core validation sites around the world. These `core sites' represent different biomes and include locations at which in situ measurements are routinely collected. The types of remotely sensed data that are being acquired and analyzed over these sites include Landsat 7 ETM+, ASTER, MODIS, and SPOT VEGETATION. The data being collected over these sites are being used to monitor ecosystem status, compile time-series records of biophysical and geophysical parameters, and to validate the suite of land products being derived from MODIS data. In order to facilitate easy access to the remotely sensed data being collected over these core sites, the data are stored online under FTP directories established by the Land Processes Distributed Active Archive Center (LP DAAC) at the USGS EROS Data Center. In situ measurements and data collected through field campaigns are being coordinated by the Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) and being made accessible through the Mercury system, which is a web-based search engine (http://mercury.ornl.gov/ornldaac/). Access to many of the remotely sensed and in situ data sets collected over the EOS Land Validation `core sites' can be accessed through Mercury or the MODIS Land Validation web page (http://modarch.gsfc.nasa.gov/MODIS/LAND/VAL/). We are hoping to stimulate interest and participation by the Validation of Land European Remote Sensing Instruments (VALERI, http://147.100.0.5/valeri//) to extend the network and diversity of sites as well as increase collaborative research. We have developed a web portal that enables investigators to select a particular site of interest, determine what data are available for that site, and select datasets for ftp download. Certain services may be requested to be applied to the data prior to download

  6. The Earth's Interaction With the Sun Over the Millennia From Analyses of Historical Sunspot, Auroral and Climate Records

    NASA Astrophysics Data System (ADS)

    Yau, K.

    2001-12-01

    A prolonged decrease in the Sun's irradiance during the Maunder Minimum has been proposed as a cause of the Little Ice Age ({ca} 1600-1800). Eddy [{Science} {192}, 1976, 1189] made this suggestion after noting that very few sunspots were observed from 1645 to 1715, indicative of a weakened Sun. Pre-telescopic Oriental sunspot records go back over 2200 years. Periods when no sunspots were seen have been documented by, {eg}, Clark [{Astron} {7}, 2/1979, 50]. Abundances of C 14 in tree rings and Be10 in ice cores are also good indicators of past solar activity. These isotopes are produced by cosmic rays high in the atmosphere. When the Sun is less active more of them are made and deposited at ground level. There is thus a strong {negative} correlation between their abundances and sunspot counts. Minima of solar activity in tree rings and a south polar ice core have been collated by, {eg}, Bard [{Earth Planet Sci Lett} {150} 1997, 453]; and show striking correspondence with periods when no sunspots were seen, centered at {ca} 900, 1050, 1500, 1700. Pang and Yau [{Eos} {79}, #45, 1998, F149] investigated the Medieval Minimum at 700, using in addition the frequency of auroral sighting7s, a good indicator of solar activity too [Yau, PhD thesis, 1988]; and found that the progression of minima in solar activity goes back to 700. Auroral frequency, C 14 and Be 10 concentrations are also affected by variations in the geomagnetic field. Deposition changes can also influence C 14 and Be 10 abundances. Sunspot counts are thus the only true indicator of solar activity. The Sun's bolometric variations (-0.3% for the Maunder Minimum) can contribute to climatic changes (\\0.5° C for the Little Ice Age)[{eg}, Lean, {GRL} {22}, 1995, 3195]. For times with no thermometer data, temperature can be estimated from, {eg}, Oxygen 18 isotopic abundance in ice cores, which in turn depends on the temperature of the ocean water it evaporated from. We have linked the Medieval Minimum to the cold

    AIM: To quantify changes in urinary excretion of aquaporin2 water channels (u-AQP2), the sodium-potassium-chloride co-transporter (u-NKCC2) and the epithelial sodium channels (u-ENaC) during treatment with bendroflumethiazide (BFTZ), amiloride and placebo. METHODS: In a randomized, double-blinded, placebo-controlled, 3-way crossover study we examined 23 healthy subjects on a standardized diet and fluid intake. The subjects were treated with amiloride 5 mg, BFTZ 1.25 mg or placebo twice a day for 4.5 d before each examination day. On the examination day, glomerular filtration rate was measured by the constant infusion clearance technique with 51Cr-EDTA as reference substance. To estimate the changes in water transport via AQP2 and sodium transport via NKCC2 and ENaC, u-NKCC2, the gamma fraction of ENaC (u-ENaCγ), and u-AQP2 were measured at baseline and after infusion with 3% hypertonic saline. U-NKCC2, u-ENaCγ, u-AQP2 and plasma concentrations of vasopressin (p-AVP), renin (PRC), angiotensin II (p-ANG II) and aldosterone (p-Aldo) were measured, by radioimmunoassay. Central blood pressure was estimated by applanation tonometry and body fluid volumes were estimated by bio-impedance spectroscopy. General linear model with repeated measures or related samples Friedman’s two-way analysis was used to compare differences. Post hoc Bonferroni correction was used for multiple comparisons of post infusion periods to baseline within each treatment group. RESULTS: At baseline there were no differences in u-NKCC2, u-ENaCγ and u-AQP2. PRC, p-Ang II and p-Aldo were increased during active treatments (P < 0.001). After hypertonic saline, u-NKCC2 increased during amiloride (6% ± 34%; P = 0.081) and increased significantly during placebo (17% ± 24%; P = 0.010). U-AQP2 increased significantly during amiloride (31% ± 22%; P < 0.001) and placebo (34% ± 27%; P < 0.001), while u-NKCC2 and u-AQP2 did not change significantly during BFTZ (-7% ± 28%; P = 0.257 and 5% ± 16%; P = 0

  8. Nitrate concentrations in river waters of the upper Thames and its tributaries.

    The spatial and temporal patterns of in-stream nitrate concentrations for the upper Thames and selected tributaries are described in relation to point and diffuse sources for these rural catchments. The rivers associated with catchments dominated by permeable (Cretaceous Chalk) bedrock show a smaller range in nitrate concentrations than those associated with clay and mixed sedimentary bedrock of lower permeability. The differences reflect the contrasting nature of water storage within the catchments and the influence of point and diffuse sources of nitrate. Nitrate concentrations often increase in a gradual way as a function of flow for the rivers draining the permeable catchments, although there is usually a minor dip in nitrate concentrations at low to intermediate flow due to (1) within-river uptake of nitrate during the spring and the summer when biological activity is particularly high and (2) a seasonal fall in the water table and a change in preferential flow-pathway in the Chalk. There is also a decrease in the average nitrate concentration downstream for the Kennet where average concentrations decrease from around 35 to 25 mg NO(3) l(-1). For the lower permeability catchments, when point source inputs are not of major significance, nitrate concentrations in the rivers increase strongly with increasing flow and level off and in some cases then decline at higher flows. When point source inputs are important, the initial increase in nitrate concentrations do not always occur and there can even be an initial dilution, since the dilution of point sources of nitrate will be lowest under low-flow conditions. For the only two tributaries of the Thames which we have monitored for over 5 years (the Pang and the Kennet), nitrate concentrations have increased over time. For the main stem of the Thames, which was also monitored for over 5 years, there is no clear increase over time. As the Pang and the Kennet river water is mainly supplied from the Chalk, the

    used here takes into account a multiobjective approach, which means that more than one objective functions are evaluated. These are the Nash-Sutcliffe efficiency (NSE) and the Absolute value of the relative bias (Absr-bias). The sensitivity analysis also provided an approximation of the optimal parameter sets so that the residual model error would originate mainly from the datasets and the model structure. JULES performance at the point scale using the default recommended parameter values was variable. The case study area is focused on the Thames catchment and more specifically on the Pang and Lambourn catchments. The examined areas are located in the WarrenFarm site, a grassland livestock site that is high on Lambourn Downs, and the Frilsham Meadow site, a grassland recharge site next to the River Pang. With the incorporation of the optimised parameters the soil moisture performance was considered reasonable so that there is no evidence that the model structure is insufficient in these catchments, and that the challenge is parameter estimation. The greater problem of parameter estimation at larger operational scales is discussed.

    Studying past climatic data can help us better understand present natural variations and predict future trends. Identification of cycles can be useful to forecasting. However, various reconstructions of the climate of the last 1000 years have given only broad similarities, with large variances in time and space [Briffa JGR 106, 2929, 2001]. For example, during the Little Ice Age (ca. 1600-1800) severe winters were frequent in Europe and China, but not over Greenland [Sci. Amer., 2/1992, 21]. The differences in modeling results are partly due to uncertainties in the past radiative forcing [Mann, Eos 82 (46), 2001]. Another outstanding question is whether we are in a time similar to Medieval Warm Period. From the frequencies of sunspot and aurora sightings, abundance of carbon-14 in the rings of long-lived trees, and beryllium-10 in the annual layers of polar ice cores, we have reconstructed the recent history of a variable Sun. In the past 1800 years the Sun has gone through nine cycles of changes in brightness. While these long-term changes account for less than one percent of the total irradiance, there is a clear evidence that they affect the climate. During the Maunder Minimum (1645-1715) few sunspots were seen--about 1 in 10 yr from China or Europe--indicative of a weak Sun. Eddy [Science 192, 1189, 1976] used historical aurora, C-14 and climate data to confirm its reality, and link it to the Little Ice Age. Using new historical sunspot catalogues [Yau, Quart. J. Roy. Astron. Soc., 29, 175, 1988], we have identified or confirmed earlier solar minima at 200-300, 400-500, 580-820, 980-1070, 1280-1350, 1410-1590; and maxima at 1080-1280, 1350-1400, etc. All these features are coincident with respective minima or maxima in the frequency of aurora sightings from Europe or Asia. Both time series are in turn consistent with radioisotope data [Pang, Eos. 9/2002]. Carbon-14 and beryllium-10 are made by cosmic rays high in the atmosphere. When the Sun is active the solar

    One possible mechanism linking inflammation with cancer involves the generation of reactive oxygen, nitrogen and halogen species by activated macrophages and neutrophils infiltrating sites of infection or tissue damage, with these chemical mediators causing damage that ultimately leads to cell death and mutation. To determine the most biologically deleterious chemistries of inflammation, we previously assessed products across the spectrum of DNA damage arising in inflamed tissues in the SJL mouse model nitric oxide over-production (Pang et al., Carcinogenesis 28: 1807–1813, 2007). Among the anticipated DNA damage chemistries, we observed significant changes only in lipid peroxidation-derived etheno adducts. We have now developed an isotope-dilution, liquid chromatography-coupled, tandem quadrupole mass spectrometric method to quantify representative species across the spectrum of RNA damage products predicted to arise at sites of inflammation, including nucleobase deamination (xanthosine, inosine), oxidation (8-oxoguanosine), and alkylation (1,N6-etheno-adenosine). Application of the method to liver, spleen, and kidney from the SJL mouse model revealed generally higher levels of oxidative background RNA damage than was observed in DNA in control mice. However, compared to control mice, RcsX treatment to induce nitric oxide overproduction resulted in significant increases only in inosine and only in the spleen. Further, the nitric oxide synthase inhibitor, N-methylarginine, did not significantly affect the levels of inosine in control and RcsX-treated mice. The differences between DNA and RNA damage in the same animal model of inflammation point to possible influences from DNA repair, RcsX-induced alterations in adenosine deaminase activity, and differential accessibility of DNA and RNA to reactive oxygen and nitrogen species as determinants of nucleic acid damage during inflammation.

  12. Pre-Venus-Transit Dark Lunar Eclipse Reveals a Very Large Volcanic Eruption in 1761

    2009-01-01

    Kepler's third law states Sun-planet distances in AU. International observations of the solar parallax during the 1761/1769 Venus transits gave us the first AU in miles. Benjamin Franklin promoted American participation in the project. While serving as Ambassador to France he observed that a "dry fog” from the 1783 Laki eruption in Iceland had obscured the Sun, and led to a cold summer and winter. Using Benjamin Franklin's method I analyzed photometric observations of the dark lunar eclipse made just before the 1761 Venus transit, ice core, tree ring, and Chinese weather data, and conclude that a very large previously unknown volcanic eruption in early 1761 had cooled the world climate. Observers worldwide found the 18 May 1761 totally eclipsed Moon very dark or invisible, e.g., Wargentin could not see the Moon for 38 minutes even with a 2-ft telescope (Phil. Trans. 52, 208, 1761-1762). Since the totally eclipsed Moon is illuminated only by sunlight refracted by the Earth's atmosphere, the obscuration must have been very severe. Ice cores from Greenland and Antarctica have large sulfuric acid contents in 1761-1762, precipitated from the global volcanic acid cloud (Zeilinski, J. Geophys. Res. 102, 26625, 1997). Frost-damaged rings in American bristlecone pines confirm that 1761 was very cold (LaMarche, Nature 307, 121, 1984). Contemporary Chinese chronicles report that heavy sustained snow fell from the Tropic of Cancer to the Yellow River. Wells and rivers froze, e.g., Taihu "Great Lake” and nearby Yangtze tributaries were not navigable. Innumerable trees, birds and livestock perished, etc. All observations are consistent with the above conclusion. Finally Benjamin Franklin's criteria for a climate-altering volcanic eruption are still universally used. Moreover his legacy continues to inspire climate researchers.

    Ye Feng composed what was to become one of the most famous and widely-circulating medical works of the late imperial period, the Treatise on Easy Childbirth. Ye Feng proposed the idea of natural childbirth, When the correct moment for birth had arrived, the child would leave its mother's body as easily as "a ripe melon drops from the stem". He argued attempts to facilitate birth were therefore not only unnecessary, and female midwives artificial intervention was not required. However, this view is to overlook the pangs of childbirth, and women bear responsibility for the failure of delivery. So his views reflect the gender order in male-dominated. Also he constructed the negative image of the midwife and belittle her childbirth techniques. As a result, midwife are excluded from the childbirth field, male doctors grasp guardianship rights of the female body. Ye Feng declared that the key to safe and successful delivery could be summed up in just a few words: "sleep, endure the pain, delay approaching the birthing tub". This view must be consistent with the Confucian norms, women to export to equip the 'patience' and 'self-control'. These norms were exposed desire men want to monitor and control the female body, effect on consolidation of patriarchal family order. In sum, the discourse of "a ripe melon drops from the stem"and "sleep, endure the pain, delay approaching the birthing tub" comprised an important intellectual resource that male doctors drew on to legitimate themselves as superior overseers of women's gestational bodies.

    Purpose: Investigating a new approach in MRI based treatment planning using the combination of (Ultrashort Echo Time) UTE and T1 weighted spin echo pulse sequences to delineate air, bone and water (soft tissues) in generating pseudo CT images comparable with CT. Methods: A gel phantom containing chicken bones, ping pang balls filled with distilled water and air bubbles, was made. It scanned with MRI using UTE and 2D T1W SE pulse sequences with (in plane resolution= 0.53mm, slice thickness= 2 mm) and CT with (in plane resolution= 0.5 mm and slice thickness= 0.75mm) as a ground truth for geometrical accuracy. The UTE and T1W SE images were registered with CT using mutual information registration algorithm provided by Philips Pinnacle treatment planning system. The phantom boundaries were detected using Canny edge detection algorithm for CT, and MR images. The bone, air bubbles and water in ping pong balls were segmented from CT images using threshold 300HU, - 950HU and 0HU, respectively. These tissue inserts were automatically segmented from combined UTE and T1W SE images using edge detection and relative intensity histograms of the phantom. The obtained segmentations of air, bone and water inserts were evaluated with those obtained from CT. Results: Bone and air can be clearly differentiated in UTE images comparable to CT. Combining UTE and T1W SE images successfully segmented the air, bone and water. The maximum segmentation differences from combine MRI images (UTE and T1W SE) and CT are within 1.3 mm, 1.1mm for bone, air, respectively. The geometric distortion of UTE sequence is small less than 1 pixel (0.53 mm) of MR image resolution. Conclusion: Our approach indicates that MRI can be used solely for treatment planning and its quality is comparable with CT.

  15. Regulation of yeast acetohydroxyacid synthase by valine and ATP.

    The first step in the common pathway for the biosynthesis of branched-chain amino acids is catalysed by acetohydroxyacid synthase (AHAS; EC 4.1.3.18). The enzyme is found in plants, fungi and bacteria, and is regulated by controls on transcription and translation, and by allosteric modulation of catalytic activity. It has long been known that the bacterial enzyme is composed of two types of subunit, and a similar arrangement has been found recently for the yeast and plant enzymes. One type of subunit contains the catalytic machinery, whereas the other has a regulatory function. Previously, we have shown [Pang and Duggleby (1999) Biochemistry 38, 5222--5231] that yeast AHAS can be reconstituted from its separately purified subunits. The reconstituted enzyme is inhibited by valine, and ATP reverses this inhibition. In the present work, we further characterize the structure and the regulatory properties of reconstituted yeast AHAS. High phosphate concentrations are required for reconstitution and it is shown that these conditions are necessary for physical association between the catalytic and regulatory subunits. It is demonstrated by CD spectral changes that ATP binds to the regulatory subunit alone, most probably as MgATP. Neither valine nor MgATP causes dissociation of the regulatory subunit from the catalytic subunit. The specificity of valine inhibition and MgATP activation are examined and it is found that the only effective analogue of either regulator of those tested is the non-hydrolysable ATP mimic, adenosine 5'-[beta,gamma-imido]triphosphate. The kinetics of regulation are studied in detail and it is shown that the activation by MgATP depends on the valine concentration in a complex manner that is consistent with a proposed quantitative model.

    A recent (2007 to 2009) dengue outbreak caused by dengue virus (DENV) in Paraguay presented unusual severe clinical outcomes associated with 50% mortality rates. Although it has been reported that inflammatory responses influence the severity of dengue virus infection (T. Pang, M. J. Cardosa, and M. G. Guzman, Immunol. Cell Biol. 85:43–45, 2007), there remains a paucity of information on virus-innate immunity interactions influencing clinical outcome. Using human dendritic cells from a major innate immune cell population as an in vitro model, we have investigated signature cytokine responses as well as infectivity-replicative profiles of DENV clinical isolates from either a nonfatal case of classical dengue fever (strain DENV3/290; isolated in Brazil in 2002) or a fatal case of dengue fever with visceral complications isolated in Paraguay in 2007 (strain DENV3/5532). Strain DENV3/5532 was found to display significantly higher replicative ability than DENV3/290 in monocyte-derived dendritic cells (mdDCs). In addition, compared to DENV3/290 results, mdDCs exposed to DENV3/5532 showed increased production of proinflammatory cytokines associated with higher rates of programmed cell death, as shown by annexin V staining. The observed phenotype was due to viral replication, and tumor necrosis factor alpha (TNF-α) appears to exert a protective effect on virus-induced mdDC apoptosis. These results suggest that the DENV3/5532 strain isolated from the fatal case replicates within human dendritic cells, modulating cell survival and synthesis of inflammatory mediators. PMID:21450836

  17. Suspended sediment and particulate phosphorus in surface waters of the upper Thames Basin, UK

    SummarySuspended sediment (SS) and particulate phosphorus (PP) concentrations in surface waters of the upper Thames Basin are reported for the main stem of the River Thames, several of its tributaries, the Cherwell, Dun, Lambourn, Pang and Thame, the Kennet and Avon Canal (that drains to the Dun and Kennet) and an artificial supply reservoir (Wilton Water). For the rivers which are mainly supplied from Chalk aquifer sources, SS and PP concentrations are poorly correlated with flow and there are issues of both biological and inorganic production of SS and PP during the spring and summer months. SS and PP are better correlated with flow when the antecedent conditions are taken into account. Thus, if flows had increased the previous day, then SS and PP concentrations are augmented. Wilton Water and the Kennet and Avon Canal have, on average, higher SS and PP concentrations than the nearby Chalk fed rivers and this probably reflects increased effects of biological activity and calcite (CaCO 3) precipitation under more stagnant conditions. For the rivers draining less permeable (clay dominated) catchments, then there is clearer linkage between flow and SS and PP concentrations. This feature reflects the more responsive influence of runoff from the land surface without the confounding issues of seasonally-varying groundwater discharges, intersection of groundwater levels with the ground surface and overland flow that may well characterise the permeable Chalk catchments. SS and PP are linearly correlated across the catchments. For the Chalk catchments and the associated Wilton Water and Kennet and Avon Canal, the PP:SS ratios are similar, ranging typically between 2 and 4 μg/mg. For the clay dominated catchments, the ratios are typically higher at 3-7 μg/mg. The results are considered in the light of process understanding, farming, climate change/climate-variability and the Water Framework Directive.

  18. Effects of Intra- and Interpatch Host Density on Egg Parasitism by Three Species of Trichogramma

    2010-01-01

    Host-foraging responses to different intra- and interpatch densities were used to assess three Trichogramma spp. (Hymenoptera: Trichogrammatidae) Trichogramma deion Pinto and Oatman, T. ostriniae Pang and Chen, and T. pretiosum Riley — as potential biological control agents for the Indian meal moth, Plodia interpunctella Hübner (Lepidoptera: Pyralidae). Single naïve females were allowed 6 h to forage in Plexiglas arenas with four different spatial arrangements of host eggs, nine single-egg patches), nine four-egg patches, 36 single-egg patches, and 36 four-egg patches. No significant differences were found among species in the number of patches parasitized. As expected, all three species parasitized the most eggs in the 36 four-egg patch treatment and the least in the nine single-egg patch treatment. T. deion parasitized significantly more eggs than T. pretiosum on the nine four-egg patches. T. ostriniae parasitized significantly more patches when intrapatch density was greater, regardless of interpatch density. In contrast, T. deion only parasitized more patches at the greater intrapatch density when the interpatch density was low. Patch density had no effect on T. pretiosum. The spatial pattern of parasitism was more aggregated for T. deion and T. ostriniae in the 36 four-egg patches treatment compared to the 36 single-egg patches treatment. Therefore, intrapatch density was more important than interpatch density for T. ostriniae, and potentially for T. deion, but not for T. pretiosum. T. deion may be the best candidate for augmentative biological control because it parasitized either slightly or significantly more eggs than the other two species in all four treatments. Furthermore, the pattern of parasitism by T. deion in the 36 four-egg patches treatment was the most aggregated among the three species, suggesting a more thorough searching pattern. In contrast, T. pretiosum had the least aggregated pattern of parasitism and therefore may have used a more

    The numerical simulation of groundwater flooding is increasingly necessary as this problem is gaining recognition from government and regulators and climate change may bring more extreme events. The Natural Environment Research Council of the UK is funding the British Geological Survey, Imperial College, and the Centre for Ecology and Hydrology to examine the problem of groundwater flooding in the Cretaceous Chalk of Berkshire, 50 kilometres west of London. Typically regional resource issues can be examined using traditional groundwater models that do not consider in detail the influence of flow in the unsaturated zone, but the delays in recharge transmission through this zone to the water table may be very significant in terms of flood timing and prediction. The position of ground elevation relative to water table is clearly important but not often considered in groundwater resource modelling. Groundwater level and stream (and flood) flow responses are important data that may be hard to gather from typical groundwater monitoring systems. These problems have been examined in a Chalk catchment in Berkshire where good records of the 2000-1 and 2003 flooding events have been collected, including flooded extent, rainfall, groundwater levels, river and spring flows. From this analysis, it appears that two groundwater mounds develop in the upper part of the Pang and Lambourn catchments. These mounds intersect dry valleys, which flowed for several months, the consequent flooding causing considerably disruption. Modelling of these events is providing new insight into the heterogeneity of Chalk transmissivity and storage parameters, enhanced knowledge of its dual permeability and porosity and demonstrating the importance of understanding the post-depositional hydrogeological history of the aquifer.

  20. A numerical study on the density driven circulation in the Yellow Sea Cold Water Mass

    2015-06-01

    The circulation of Yellow Sea Cold Water Mass (YSCWM) in the Southern Yellow Sea is investigated using a diagnostic 2D MITgcm model. The resolution of the computational grid is 900 m in the horizontal and 2 m in the vertical where an initial temperature distribution corresponding to a typical measured Yellow Sea Cold Water Mass was applied. The existence of YSCWM that causes fluid density difference, is shown to produce counter-rotating cyclonic horizontal eddies in the surface layer: the inner one is anti-cyclonic (clockwise) and relatively weaker (8-10 cm s-1) while the outer one is cyclonic (anti-clockwise) and much stronger (15-20 cm s-1). This result is consistent with the surface pattern observed by Pang et al. (2004), who has shown that a mesoscale anti-cyclonic eddy (clockwise) exists in the upper layer of central southern Yellow Sea, and a basin-scale cyclonic (anticlockwise) gyre lies outside of the anti-cyclonic eddy, based on the trajectories and drifting velocities of 23 drifters. Below the thermocline, there is an anti-cyclonic (clockwise) circulation. This complex current eddy system is considered to be capable of trapping suspended sediments and depositing them near the front between YSCWM and the coastal waters off the Subei coast, providing an explanation on the sediment depth and size distribution of mud patches in the Southern Yellow Sea. Moreover, sensitive test scenarios indicate that variations of bottom friction do not substantially change the main features of the circulation structure, but will reduce the bottom current velocity, increase the surface current velocity and weaken the upwelling around the frontal area.

    KENNEDY SPACE CENTER, FLA. - Seen through the lush Florida landscape, Space Shuttle Endeavour comes to a stop on runway 33 at the Shuttle Landing Facility after completing the 13-day, 18-hour, 48-minute, 5.74-million mile STS-113 mission to the International Space Station. Main gear touchdown was at 2:37:12 p.m. EST, nose gear touchdown was at 2:37:23 p.m., and wheel stop was at 2:38:25 p.m. Poor weather conditions thwarted landing opportunities until a fourth day, the first time in Shuttle program history that a landing has been waved off for three consecutive days. The vehicle carries the STS-113 crew, Commander James Wetherbee, Pilot Paul Lockhart and Mission Specialists Michael Lopez-Alegria and John Herrington, as well as the returning Expedition Five crew, Commander Valeri Korzun, ISS Science Officer Peggy Whitson and Flight Engineer Sergei Treschev. The installation of the P1 truss on the International Space Station was accomplished during the mission.

  6. Top-down effects of syntactic sentential context on phonetic processing.

    Fox, Neal P; Blumstein, Sheila E

    2016-05-01

    Although much evidence suggests that the identification of phonetically ambiguous target words can be biased by preceding sentential context, interactive and autonomous models of speech perception disagree as to the mechanism by which higher level information affects subjects' responses. Some have suggested that the time course of context effects is incompatible with interactive models (e.g., TRACE). Two experiments examine this issue. In Experiment 1, subjects heard noun- and verb-biasing sentence contexts (e.g., Valerie hated the . . . vs. Brett hated to . . .), followed by stimuli from 2 voice-onset time continua: bay-pay (noun-verb) versus buy-pie (verb-noun). Consistent with prior research, identification of phonetically ambiguous targets was biased by the preceding context, and the size of this bias diminished in slower compared with faster responses. In Experiment 2, tokens from the same continua were embedded among filler target words beginning with /b/ or /p/ to elicit phonemically driven identification decisions and discourage word-level strategies. Results again revealed contextually biased responding, but this bias was as strong in slow as in fast responses. Together, these results suggest that phoneme identification decisions reflect robust, lasting top-down effects of lexical feedback on prelexical representations, as predicted by interactive models of speech perception.

    STS-91 Mission Commander Charles J. Precourt (at microphone) presents an American flag, a special tool, and an optical disc to NASA Administrator Dan Goldin following Discovery's landing at KSC's Shuttle Landing Facility, as Phase I Shuttle/Mir Program Manager Frank Culbertson and the other members of the STS-91 flight crew look on. This landing not only concluded the STS-91 mission, but Phase I of the joint U.S.-Russian International Space Station Program as well. The flag rode aboard Mir from the beginning of the Phase I program and was brought back to Earth by the STS-91 crew. Discovery's main gear touchdown on Runway 15 was at 2:00:00 p.m. EDT on June 12, 1998, on orbit 155 of the mission. The wheels stopped at 2:01:00 p.m. EDT, for a total mission-elapsed time of 9 days, 19 hours, 55 minutes and 1 second. The 91st Shuttle mission was the 44th KSC landing in the history of the Space Shuttle program and the 15th consecutive landing at KSC. Besides Commander Precourt, the STS-91 flight crew also included Pilot Dominic L. Gorie and Mission Specialists Wendy B. Lawrence, Franklin R. Chang-Diaz, Janet Lynn Kavandi and Valery Victorovitch Ryumin of the Russian Space Agency. Astronaut Andrew S. W.

    Glucose 6-phosphate, fructose 6-phosphate, fructose 1, 6-diphosphate, and triose phosphates, and the enzymes phosphofructokinase, aldolase, and glucose 6-phosphate dehydrogenase were extracted from banana fruit (Musa cavendishii, Lambert var. Valery) at the (a) preclimacteric, (b) climacteric rise, (c) climacteric peak, and (d) postclimacteric stages of ripening. The level of fructose 1, 6-diphosphate increased 20-fold whereas the concentration of other intermediates changed no more than 2.5-fold between stages a and c. For these same extracts, phosphofructokinase activity increased 2.5-fold whereas the activity of glucose 6-phosphate dehydrogenase and aldolase changed only fractionally. Substrate saturation studies (fructose 6-phosphate) of phosphofructokinase activity showed a decrease in the [S](0.5) from 5.6 to 1.7 mM betwen stages a and c. The enzyme from both sources seems to be regulated by a negative cooperative effect with the control being more stringent in the enzyme from stage a. The difference in enzyme activity is consistent with the increase in respiratory activity between the two stages. PMID:16659026

    Startled by the almost silent appearance of the orbiter Discovery as it lands following the STS-91 mission, several birds hurriedly leave KSC's Shuttle Landing Facility (SLF) for a more secluded spot. The SLF is nestled among the wilds of the Merritt Island National Wildlife Refuge, home to over 300 species of birds. Discovery's main gear touchdown on Runway 15 was at 2:00:18 p.m. EDT on June 12, 1998, landing on orbit 155 of the mission. The wheels stopped at 2:01:22 p.m. EDT, for a total mission-elapsed time of 9 days, 19 hours, 55 minutes and 1 second. The 91st Shuttle mission was the 44th KSC landing in the history of the Space Shuttle program and the 15th consecutive landing at KSC. During the mission, the orbiter docked with the Russian space station Mir for the ninth time, concluding Phase I of the joint U.S.-Russian International Space Station Program.

    2002-01-01

    On Flight Day 3 of STS-111, the crew of Endeavour (Kenneth Cockrell, Commander; Paul Lockhart, Pilot; Franklin Chang-Diaz, Mission Specialist; Philippe Perrin, Mission Specialist) and the Expedition 5 crew (Valery Korzun, Commander; Peggy Whitson, Flight Engineer; Sergei Treschev, Flight Engineer), begin their final approach towards the International Space Station (ISS). From cameras aboard the ISS, live video of Endeavour is shown as it approaches the station. The Orbiter is maneuvered slowly to a position for docking, and cameras from multiple angles show this process. As it is maneuvered, there are clear views of its payload bay, which includes the Leonardo MultiPurpose Logistics Module (MPLM) and the Mobile Base System (MBS), both of which will be installed on the ISS during this mission. In the final stages of the docking procedure there is close-up footage of Endeavour meeting the ISS's Pressurized Mating Adapter 2 on the Destiny Laboratory Module. Inside the ISS, the Expedition 4 crew (Yury Onufrienko, Commander; Daniel Bursch, Flight Engineer; Carl Walz, Flight Engineer), which will be replaced by the Expedition 5 crew, prepares for final docking. Crew members are shown transferring equipment from the Endeavour to the ISS, prior to a replay of the mating of the two crafts. In the replay, the hatch is shown being opened and the two newly arrived crews are greeted with excitement by Expedition 4 crewmembers. The video closes with footage of the Quest airlock used for EVA (extravehicular activity) egress, and the Canadarm 2 robotic arm.

    Under the supervision of Boeing technicians, the Alpha Magnetic Spectrometer (AMS), a payload slated to fly on STS-91, is undergoing a final weight and balance check on the Launch Package Integration Stand in the Space Station Processing Facility (SSPF). Next, it will be placed in the Payload Canister and transported to Launch Complex 39A where it will be installed into Space Shuttle Discovery's payload bay. Weighing in at approximately three tons, the AMS is a major particle physics experiment that will look for cosmic antimatter originating from outside our galaxy. The data it gathers could also give clues about the mysterious 'dark matter' that may make up 90 percent or more of the universe. STS-91 is scheduled to be launched on June 2 with a launch window opening around 6:10 p.m. EDT. The mission will also feature the ninth Shuttle docking with the Russian Space Station Mir, the first Mir docking for Discovery, and the conclusion of Phase I of the joint U.S.-Russian International Space Station Program. The STS-91 flight crew includes Commander Charles Precourt; Pilot Dominic Gorie; and Mission Specialists Wendy B.

  8. Physicists for Human Rights in the Former Soviet Union

    In his 1940 paper `Freedom and Science' Albert Einstein emphasized that ``intellectual independence is a primary necessity for the scientific inquirer'' and that ``political liberty is also extraordinarily important for his work.'' Raised in the tradition of intellectual independence and dedicated to the scientific truth, physicists were among the first to stand up for freedom in the USSR. It was no coincidence that the founders of the first independent Human Rights Committee (1970) were physicists: Andrei Sakharov, Valery Chalidze and Andrei Tverdokhlebov. In 1973 a physicist, Alexander Voronel, founded a Moscow Sunday (refusenik) Seminar -- the first openly independent scientific body in the history of the USSR. In 1976 physicists Andrei Sakharov, Yuri Orlov and a mathematician Natan Sharansky were the leading force in founding the famous Moscow Helsinki Human Rights Watch group. This talk briefly describes the special position of physicists (often viewed as Einstein's colleagues) in Soviet society, as well as their unique role in the struggle for human rights. It describes in some detail the Moscow Sunday Seminar, and extensions thereof such as International Conferences, the Computer School and the Computer Database of Refuseniks. The Soviet government considered such truly independent organizations as a challenge to Soviet authority and tried to destroy them. The Seminar's success and its very existence owed much to the support of Western scientific organizations, who persuaded their members to attend the Seminar and visit scientist-refuseniks. The human rights struggle led by physicists contributed substantially to the demise of the Soviet system.

The mission will feature the ninth Shuttle docking with the Russian Space Station Mir, the first Mir docking for Discovery, the conclusion of Phase I of the joint U.S.-Russian International Space Station Program, and the first flight of the new Space Shuttle super lightweight external tank. The STS-91 flight crew also includes Pilot Dominic Gorie and Mission Specialists Wendy B. Lawrence; Franklin Chang- Diaz, Ph.D.; and Janet Kavandi, Ph.D. Andrew Thomas, Ph.D., will be returning to Earth with the crew after living more than four months aboard Mir.

  15. Cooling Atomic Gases With Disorder

    NASA Astrophysics Data System (ADS)

    Scalettar, Richard

    Cold atomic gases have proven capable of emulating a number of fundamental condensed matter phenomena including Bose-Einstein condensation, the Mott transition, Fulde-Ferrell-Larkin-Ovchinnikov pairing and the quantum Hall effect. Cooling to a low enough temperature to explore magnetism and exotic superconductivity in lattices of fermionic atoms remains a challenge. We propose a method to produce a low temperature gas by preparing it in a disordered potential and following a constant entropy trajectory to deliver the gas into a non-disordered state which exhibits these incompletely understood phases. We show, using quantum Monte Carlo simulations, that we can approach the Neél temperature of the three-dimensional Hubbard model for experimentally achievable parameters. Recent experimental estimates suggest the randomness required lies in a regime where atom transport and equilibration are still robust.

  16. Computational study of lattice models

    NASA Astrophysics Data System (ADS)

    Zujev, Aleksander

    This dissertation is composed of the descriptions of a few projects undertook to complete my doctorate at the University of California, Davis. Different as they are, the common feature of them is that they all deal with simulations of lattice models, and physics which results from interparticle interactions. As an example, both the Feynman-Kikuchi model (Chapter 3) and Bose-Fermi mixture (Chapter 4) deal with the conditions under which superfluid transitions occur. The dissertation is divided into two parts. Part I (Chapters 1-2) is theoretical. It describes the systems we study - superfluidity and particularly superfluid helium, and optical lattices. The numerical methods of working with them are described. The use of Monte Carlo methods is another unifying theme of the different projects in this thesis. Part II (Chapters 3-6) deals with applications. It consists of 4 chapters describing different projects. Two of them, Feynman-Kikuchi model, and Bose-Fermi mixture are finished and published. The work done on t - J model, described in Chapter 5, is more preliminary, and the project is far from complete. A preliminary report on it was given on 2009 APS March meeting. The Isentropic project, described in the last chapter, is finished. A report on it was given on 2010 APS March meeting, and a paper is in preparation. The quantum simulation program used for Bose-Fermi mixture project was written by our collaborators Valery Rousseau and Peter Denteneer. I had written my own code for the other projects.

STS- 96, scheduled for liftoff on May 20 at 9:32 a.m., is a logistics and resupply mission for the International Space Station, carrying such payloads as a Russian crane, the Strela; a U.S.- built crane; the Spacehab Oceaneering Space System Box (SHOSS), a logistics items carrier; and STARSHINE, a student-led experiment.

  18. Transition from superlubrically sliding islands to pinned monolayer, demonstrated in Xe/Cu(111)

    NASA Astrophysics Data System (ADS)

    Guerra, Roberto; Vanossi, Andrea; Tosatti, Erio; Trieste Nanofriction Team

    A molecular dynamics simulation case study of Xe on Cu(111) reveals unexpected information on the exceptionally smooth sliding state associated with incommensurate superlubricity which is argued to emerge in the large size limit of naturally incommensurate Xe islands. As coverage approaches a full monolayer, theory predicts an abrupt adhesion-driven two-dimensional density compression on the order of several per cent, implying a hysteretic jump from superlubric free islands to a pressurized sqrt()x sqrt()commensurate (and pinned, and therefore immobile) monolayer. These results match with recent quartz crystal microbalance data which show remarkably large slip times with increasing submonolayer coverage, signalling superlubricity, followed by a dramatic drop to zero for the dense commensurate monolayer. Careful analysis of this variety of island sliding phenomena should be essential in future applications of friction at crystal/adsorbate interfaces. Matching experimental work by M. Pierno, L.

  7. Generation and Properties of Large-Scale Non-axisymmetric Magnetic Fields by Solar Dynamo

    Large-scale non-axisymmetric magnetic fields generated by the solar dynamo, and presumably responsible for the phenomenon of "active longitudes", play an important role in the distribution of solar activity and flares. By calculating 3D mean-field dynamo models, we show that nonlinear coupling between axisymmetric and non-axisymmetric modes, e.g. due to the magnetic feedback on the alpha-effect (see, e.g., [1]), can maintain a large-scale non-axisymmetric dynamo process. Non-axisymmetric random fluctuations of dynamo parameters can be another source for the non-axisymmetric magnetic fields on the Sun. Such fluctuations can provide a mechanism of the magnetic energy transfer from the global field to the non-axisymmetric modes. It is shown that the rotational periods of the non-axisymmetric field correspond to the dynamo process operating in the subsurface shear layer which is located in the range of depths 0.85-0.95R. We find that the magnetic helicity conservation quenches generation of the non-axisymmetric dynamo modes as well as it does for the axisymmetric dynamo. It is concluded that the 3D mean-field non-axisymmetric dynamo models can potentially explain the observed distribution of the solar magnetic activity.1.

    1999-01-01

    In this first part of a three-part video mission-highlights set, the flight of the STS-96 Space Shuttle Orbiter Discovery is reviewed. The flight crew consists of Kent V. Rominger, Commander; Rick D. Husband, Pilot; and Mission Specialists Ellen Ochoa, Tamara E. Jernigan, Daniel T. Barry, Julie Payette (Canadian), and Valery Ivanovich Tokarev (Russian). The primary goals of this mission were to work on logistics and resupply the International Space Station (ISS). This is the first flight to dock to the International Space Station. The primary payloads are the Russian cargo crane, known as STRELA, which the astronauts mount to the exterior of the Russian station segment, the SPACEHAB Oceaneering Space System Box (SHOSS), and a U.S. built crane called the ORU Transfer Device (OTD). Other payloads include the Student Tracked Atmospheric Research Satellite for Heuristic International Networking Equipment (STARSHINE), the Shuttle Vibration Forces Experiment (SVF), and the Orbiter Integrated Vehicle Health Monitoring - HEDS Technology Demonstration (IVHM HTD). The traditional pre-launch breakfast, being suited up, entry into the Shuttle, and views of the liftoff from several different vantage points are shown. In-flight footage includes views from the robot arm conducting a television survey of Discovery's payload bay and the flawless docking of the Unity module with the International Space Station. During the docking, camera views from both the ISS and Discovery are presented. These activities make up the first three Flight Days of STS-96.

    This artist's concept depicts the Apollo-Soyuz Test Project (ASTP), the first international docking of the U.S.'s Apollo spacecraft and the U.S.S.R.'s Soyuz spacecraft in space. The objective of the ASTP mission was to provide the basis for a standardized international system for docking of marned spacecraft. The Soyuz spacecraft, with Cosmonauts Alexei Leonov and Valeri Kubasov aboard, was launched from the Baikonur Cosmodrome near Tyuratam in the Kazakh, Soviet Socialist Republic, at 8:20 a.m. (EDT) on July 15, 1975. The Apollo spacecraft, with Astronauts Thomas Stafford, Vance Brand, and Donald Slayton aboard, was launched from Launch Complex 39B, Kennedy Space Center, Florida, at 3:50 p.m. (EDT) on July 15, 1975. The Primary objectives of the ASTP were achieved. They performed spacecraft rendezvous, docking and undocking, conducted intervehicular crew transfer, and demonstrated the interaction of U.S. and U.S.S.R. control centers and spacecraft crews. The mission marked the last use of a Saturn launch vehicle. The Marshall Space Flight Center was responsible for development and sustaining engineering of the Saturn IB launch vehicle during the mission.
