GRAVITATIONAL MICROLENSING BY THE ELLIS WORMHOLE  

SciTech Connect

A method to calculate light curves of the gravitational microlensing of the Ellis wormhole is derived in the weak-field limit. In this limit, lensing by the wormhole produces one image outside the Einstein ring and another image inside. The weak-field hypothesis is a good approximation in Galactic lensing if the throat radius is less than 10{sup 11} km. The light curves calculated have gutters of approximately 4% immediately outside the Einstein ring crossing times. The magnification of the Ellis wormhole lensing is generally less than that of Schwarzschild lensing. The optical depths and event rates are calculated for the Galactic bulge and Large Magellanic Cloud fields according to bound and unbound hypotheses. If the wormholes have throat radii between 100 and 10{sup 7} km, are bound to the galaxy, and have a number density that is approximately that of ordinary stars, detection can be achieved by reanalyzing past data. If the wormholes are unbound, detection using past data is impossible.

Changes in bathymetry for Lake Katherine and Wood Lake, Richland County, South Carolina, 1989-93  

USGS Publications Warehouse

Bathymetric surveys of Lake Katherine and Wood Lake, small residential lakes in Columbia, South Carolina, were made in 1989 and 1993. During this period the combined volume of the lakes decreased by 519,000 cubic feet (11.9 acre-feet). Most of the decrease in volume occurred in the northern part of Lake Katherine where deltaic sediment deposits at the mouth of Gills Creek increased in thickness during the 4-year period. The sediment was derived from a combination of sources in the Gills Creek Basin upstream from the lakes. Construction of a highway and a housing development in the Basin were significant factors in the sedimentation.

Wave effect in gravitational lensing by the Ellis wormhole  

NASA Astrophysics Data System (ADS)

We propose the use of modulated spectra of astronomical sources due to gravitational lensing to probe Ellis wormholes. The modulation factor due to gravitational lensing by the Ellis wormhole is calculated. Within the geometrical optics approximation, the normal point-mass lens and the Ellis wormhole are indistinguishable unless we know the source’s unlensed luminosity. This degeneracy is resolved with the significant wave effect in the low-frequency domain if we take the deviation from the geometrical optics into account. We can roughly estimate the upper bound for the number density of Ellis wormholes as n?4×10-10AU-3 with throat radius a˜1cm from the existing femtolensing analysis for compact objects.

Magnetoplasmadynamcis - Portrait of Macon C. 'Mike' Ellis, Jr  

NASA Technical Reports Server (NTRS)

Portrait of Macon C. 'Mike' Ellis, Jr. James Hansen described Mike Ellis as 'the first and only person to be in charge of Langley's Magnetoplasmadynamcis (MPD) Branch.' He was 'an NACA veteran who was 42 years old when the branch was organized. Ellis had come to work at Langley in 1939, and over the course of his career at the laboratory, he had been involved in pioneering work on the aerodynamics of jet engines, ramjets, and supersonic inlets and nozzles. Fittingly, Ellis had worked for Eastman Jacobs and with Arthur Kantrowitz in the early 1940s, and he had heard firsthand accounts of his former colleagues' attempts to design a fusion reactor in the spring of 1938. By the late 1950s, Ellis was one of Langley's most outspoken believers in MPD's promise of technological benefits. Ellis encouraged Floyd Thompson's enthusiasm for MPD and persuaded Langley's senior staff of mostly engineers that MPD was a field of research vital to the future of NASA. When the time came to pick someone to head the new branch, Ellis was unquestionably the person for the job. 'Ellis was no extraordinary 'scientific brain.' As an aeronautical engineer, his talents were quite respectable, but he possessed no special competency in the physics of fluids beyond his experience in aerodynamics or gas dynamics. He was always the first to admit that the complexities of plasma physics and MPD were such that 'there was no way' that he personally could conduct basic MPD research. That challenge he would leave to minds more suited for it. But Ellis could bring the MPD researchers together as a unit, serve as their strong external advocate, shield them from front-office pressures, and make sure that they received the support they needed to carry out their work. 'I just tried to keep my head above water,' Ellis explains, 'and keep these *mad scientists' from going off on too many tangents, or going mad myself.' Published in James R. Hansen, Spaceflight Revolution: NASA Langley Research Center From Sputnik to Apollo, NASA SP-4308, pp.127, 129.

Stability of the Thin-Shell Schwarzschild-Ellis Wormhole  

NASA Astrophysics Data System (ADS)

We investigate the stability regions of the thin-shells obtained by gluing the exterior Schwarzschild vacuum with two distinct classes of Ellis wormholes, one with zero and the other with nonzero total mass. Using the new concepts of thin-shell "mass" and of "external force" discovered recently by Garcia, Lobo and Visser, we shall apply their method to the explicit cases where some of the energy conditions in the bulk (on two sides) are violated. The stability regions are analyzed and the energetics is briefly discussed. Remarkably, we find that the stability zones are quite similar although the classes of Ellis wormholes are different. By the present examples, we confirm that the stability zones indicated by the force constraint (involving ? and its derivatives) are more complete but restrictive than those from the mass constraint (not involving ?).

X-Ray Spectroscopy, The Ellen Richards Prize, and Nuclear Proliferation: The Inspiring Life of Katherine Chamberlain  

NASA Astrophysics Data System (ADS)

In 1924, Katherine Chamberlain became the first woman to receive a doctorate in physics from the University of Michigan. As one of the first women in the world to earn a doctorate in physics, Katherine reached a level prominence in the scientific community that few women had achieved. As a scientist, Katherine studied the outer energy levels of various elements using x-ray spectroscopy at the University of Michigan. In her thesis, she showed the potential for x-rays to reduce highly oxidized compounds and in 1925 won the Ellen Richards Prize for the world's best scientific paper by a woman. As an educator, she taught an introduction to photography course for thirty-five years in the hopes of creating new ways to inspire a love for physics in her students. As a community leader, she worked with The United World Federalists and The Michigan Memorial Phoenix Project to find peaceful uses for nuclear energy. Looking at these aspects of Chamberlain's life offers a unique perspective on the physics community of the 1920's, physics education, and the nuclear panic that followed WWII.

Mandibular Angle Fractures: A Clinical and Biomechanical Comparison--the Works of Ellis and Haug  

PubMed Central

In a series of articles spanning 8 years, Ed Ellis reviewed the clinical results of the treatment of 478 mandibular angle fractures managed by eight different techniques. During a series of benchtop investigations employing polyurethane synthetic mandible replicas, Rich Haug investigated the biomechanical behavior of approximately 15 different techniques designed to reconstruct mandibular angle fractures. This article reviews these two series of investigations in an attempt to gain insight into the biomechanical and biological factors that affect the successful reconstruction of mandibular angle fractures. It appears that the current techniques used to reconstruct mandibular angle fractures are sound from the standpoint of biomechanics within a range of forces encountered during clinical function. It also appears that an unsuccessful reconstruction is based on a biological result of a behavioral issue such as noncompliance, substance abuse, and/or nutritional or immune compromise.

Tritium-enrichment via CECE-process with high temperature steam electrolysis (HOT ELLY)  

SciTech Connect

Aqueous waste which is a by-product of nuclear fuel reprocessing plants, is contaminated with tritium in the form of HTO. This waste must be disposed of in a suitable compact manner. In order to minimize waste volume, tritiated water is enriched by several orders of magnitude of its original concentration. This task is accomplished by using the existing combined electrolysis catalytic exchange (CECE)-Process, which is presently in pilot operation with tritium in a German nuclear research facility (Kernforschungszentrum Karlsruhe, KfK, FRG). Substantial energy reduction can be achieved by substituting the conventional water electrolysis by high-temperature steam electrolysis (HOT ELLY) for separating tritiated water into its components.

Stability analysis of a Morris-Thorne-Bronnikov-Ellis wormhole with pressure  

NASA Astrophysics Data System (ADS)

The model of a spherical Morris-Thorne-Bronnikov-Ellis wormhole is analyzed for stability. The matter of this wormhole is composed of a radial monopole magnetic field and a quasi-perfect phantom fluid. In the stationary case, the energy density of this fluid is negative and equal in magnitude to twice the energy density of the magnetic field. There is no pressure of this fluid in the stationary case (phantom dust), while in the case where the fluid energy density deviates from its stationary value, the pressure is proportional to the deviation of the energy density from its stationary value. An example of a wormhole stable against radial perturbations has been obtained.

We suppose that the solar neutrino problem is due only to the mechanism introduced by Ellis, Hagelin, Nanopoulos and Srednicki (EHNS) to allow pure quantum states to evolve into mixed ones. Lower limits on the EHNS parameters 0954-3899/24/12/014/img7 are obtained. We find that 0954-3899/24/12/014/img8 GeV if 0954-3899/24/12/014/img9 and 0954-3899/24/12/014/img10 GeV if 0954-3899/24/12/014/img11, with no constraint on 0954-3899/24/12/014/img12. This limit is consistent with the upper limits extracted from the 0954-3899/24/12/014/img13 system and can be detected in future experiments.

Active movements in plants: Mechanism of trap closure by Dionaea muscipula Ellis.  

PubMed

The Venus flytrap (Dionaea muscipula Ellis) captures insects with one of the most rapid movements in the plant kingdom. We investigated trap closure by mechanical and electrical stimuli using the novel charge-injection method and high-speed recording. We proposed a new hydroelastic curvature mechanism, which is based on the assumption that the lobes possess curvature elasticity and are composed of outer and inner hydraulic layers with different hydrostatic pressure. The open state of the trap contains high elastic energy accumulated due to the hydrostatic pressure difference between the hydraulic layers of the lobe. Stimuli open pores connecting the two layers, water rushes from one hydraulic layer to another, and the trap relaxes to the equilibrium configuration corresponding to the closed state. In this paper we derived equations describing this system based on elasticity Hamiltonian and found closing kinetics. The novel charge-injection stimulation method gives insight into mechanisms of the different steps of signal transduction and response in the plant kingdom. PMID:19513230

Temporal Patterns of Protozooplankton Abundance and Their Food in Ellis Fjord, Princess Elizabeth Land, Eastern Antarctica  

NASA Astrophysics Data System (ADS)

The abundance and biomass of ciliates, dinoflagellates and heterotrophic and phototrophic nanoflagellates were determined at three sites along an ice-covered Antarctic fjord between January and November 1993. The water column showed little in the way of temperature and salinity gradients during the study period. In general, the protozooplankton exhibited a seasonal variation which closely mirrored that of chlorophyll aand bacterioplankton. The fjord mouth, which was affected by the greatest marine influences, consistently had the highest densities of ciliates and the most diverse community, with up to 18 species during the sampling period. Small aloricate ciliates were present throughout the year with Strobilidiumspp. being dominant during the winter. Larger loricate and aloricate ciliates became more prominent during January and November, along with the autotrophic ciliate Mesodinium rubrumand two mixotrophic species ( Strombidium wulffiand a type resembling Tontonia) suggesting evidence of species successions. Data on dinoflagellates were less extensive, but these protists showed greatest species diversity in the middle reaches of the fjord. A total of 13 species of dinoflagellate was recorded. Ciliates made a significant contribution to the biomass of the microbial community in summer, particularly in the middle and at the seaward end of the fjord. In winter, heterotrophic flagellates (HNAN) and phototrophic nanoflagellates (PNAN) were the dominant component of protistan biomass. In terms of percentage contribution to the microbial carbon pool, bacteria dominated during winter and spring. To the authors' knowledge, this is the first seasonal study of an Antarctic fjord. The Ellis Fjord is very unproductive compared to lower latitude systems, and supports low biomass of phytoplankton and microbial plankton during most of the year. This relates to severe climatic and seasonal conditions, and the lack of allochthonous carbon inputs to the system. Thus, high latitude estuaries may differ significantly from lower latitude systems, which generally rank among the most productive aquatic systems in the world.

Biomimetic robotic Venus flytrap (Dionaea muscipula Ellis) made with ionic polymer metal composites.  

PubMed

The work described in this paper is a novel design of a robotic Venus flytrap (VFT) (Dionaea muscipula Ellis) by means of ionic polymeric metal composite (IPMC) artificial muscles as distributed nanosensors and nanoactuators. Rapid muscular movements in carnivorous plants, such as VFT, which are triggered by antenna-like sensors (trigger hair), present a golden key to study distributed biomolecular motors. Carnivorous plants, such as VFT, possess built-in intelligence (trigger hairs), as a strategy to capture prey, that can be turned on in a controlled manner. In the case of the VFT, the prey that is lured by the sweet nectar in the VFT pair of jaw-like lobes has to flip and move the trigger hairs, which are colorless, bristle-like and pointed. The dynamically moved trigger hairs then electro-elastically send an electric signal to the internal ions in the lobe to migrate outwardly for the jaw-like lobes to close rapidly to capture the prey. The manner in which the VFT lobes bend inward to capture the prey shows a remarkable similarity with typical IPMCs bending in an electric field. Furthermore, the mechano-electrical sensing characteristics of IPMCs also show a remarkable resemblance to mechano-electrical trigger hairs on the lobes of the VFT. The reader is referred to a number of papers in connection with sensing and actuation of IPMCs in particular. Thus, one can integrate IPMC lobes with a common electrode in the middle of one end of the lobes to act like a spine and use IPMC bristles as trigger finger to sense the intrusion of a fly or insect to send a sensing signal to a solid state relay which then triggers the actuation circuit of the IPMC lobes to rapidly bend toward each other and close. The two lobes, which form the trap, are attached to the midrib common electrode which is conveniently termed the spine. The upper surface of each lobe is dished, and spaced along the free margins of the lobes with some 15-20 prong-like teeth. These are tough and pointed, and are inclined at an inward angle so that when the trap is sprung shut they will interlock. We have been experimenting with the VFT closing of its jaw-like lobes that close in about 0.3 s and have gained a lot of knowledge to report on the ionic and electrical mechanisms involved in the operation of such intelligent distributed biomolecular motors.

The influence of secretion elicitors and external pH on the kinetics of D-alanine uptake by the trap lobes of Dionaea muscipula Ellis (Venus's Flytrap)  

Microsoft Academic Search

Simple kinetic techniques were used to examine the mechanism of D-alanine uptake by the adaxial surfaces of the trap lobes of Dionaea muscipula Ellis (Venus's Flytrap.) On the basis of these analyses, the uptake of D-alanine was found to depend on the time during which the trap lobes were inoculated with elicitors of secretion before excision and measurement of uptake.

Observational Upper Bound on the Cosmic Abundances of Negative-mass Compact Objects and Ellis Wormholes from the Sloan Digital Sky Survey Quasar Lens Search  

NASA Astrophysics Data System (ADS)

The latest result in the Sloan Digital Sky Survey Quasar Lens Search (SQLS) has set the first cosmological constraints on negative-mass compact objects and Ellis wormholes. There are no multiple images lensed by the above two exotic objects for ~50, 000 distant quasars in the SQLS data. Therefore, an upper bound is put on the cosmic abundances of these lenses. The number density of negative-mass compact objects is n < 10-8(10-4) h 3 Mpc-3 at the mass scale |M| > 1015(1012) M ?, which corresponds to the cosmological density parameter |?| < 10-4 at the galaxy and cluster mass range |M| = 1012-15 M ?. The number density of the Ellis wormhole is n < 10-4 h 3 Mpc-3 for a range of the throat radius a = 10-104 pc, which is much smaller than the Einstein ring radius.

The Effect of Various Media and Hormones via Suspension Culture on Secondary Metabolic Activities of (Cape Jasmine) Gardenia jasminoides Ellis  

PubMed Central

The leaf of Gardenia jasminoides Ellis was used as explants and was cultured on MS and WPM media supplemented with various concentrations of NAA, IAA, 2,4-D, IBA, TDZ, and Kn (0 to 5?mg?L?1 with 0.5 increment). After six months, the higher percentage of callus (100%) and the best dry and fresh weight of callus were formed on WPM medium supplemented with 2,4-D and NAA (2.0-3.0?mg?L?1) and this amount was decreased from (84%) to (69%) when this media supplemented with Kinetin and TDZ (1?mg?L?1) respectively were used. Leaf segments cultured on WPM media added with Kn (1?mg?L?1) and TDZ (2?mg?L?1) yielded the least amount of callus. It was found that WPM media added with IAA (4.5–5.0?mg?L?1) were optimum for root induction from G. jasminoides plantlets. Antibacterial screening of leaf extracts (in vivo) showed no inhibitory effect against E. coli, P. aeruginosa, S. aureus, and B. cereus, in contrast to callus extracts from leaf cultures supplemented with NAA, which showed inhibition activity against E. coli and B. cereus. The callus extracts from leaf cultures grown on both MS and WPM media showed higher antioxidant and superoxide dismutase activities than leaf extracts.

The biosynthesis of palladium nanoparticles by antioxidants in Gardenia jasminoides Ellis: long lifetime nanocatalysts for p-nitrotoluene hydrogenation  

NASA Astrophysics Data System (ADS)

Gardenia jasminoides Ellis' water crude extract was used for the bioreduction of palladium chloride in this paper. The UV-vis spectrum, x-ray diffraction spectrum measurement, the Fourier transform infrared spectroscopy and TEM technique confirmed the formation of palladium nanoparticles and identified antioxidants including geniposide, chlorogenic acid, crocins and crocetin were reducing and stabilizing agents for synthesizing palladium nanoparticles in water crude extract. The particle size and dispersity were temperature-dependent. The particle sizes ranged from 3 to 5 nm and revealed the best dispersity at 70 °C. Catalytic performance of the biosynthetic Pd nanoparticles with good dispersity was investigated by hydrogenation of p-nitrotoluene. The catalysts showed a conversion of 100% under conditions of 5 MPa, 150 °C for 2 h. The selectivity of p-methyl-cyclohexylamine achieved 26.3%. The catalyst was recycled five times with no agglomeration and maintained activity, which was attributed to the appropriate protection of the antioxidants. On the basis of the study, it appears to be a new promising biosynthetic nanocatalyst for the development of an industrial process.

PubMed

Conidia of Torula caligans (Batista & Upadhyay) M. B. Ellis comb.nov. and T. terrestris Misra were examined by transmission- and scanning-electron microscopy. Torula caligans produced four-celled conidia in which the central cells were distinctly larger than the basal and apical cells. Conidia of T. terrestris were 4- to 7-celled long and ellipsoidal in shape. Conidiogenous cells in both species developed melanin only within the lowermost part of the lateral walls while the other cells of the conidium were uniformly melanized around the circumference of the cell; melanin in these cells being deposited within, at least, half the width of the cell wall. In both species new conidia arose from evagination of the hyaline apex of the conidiogenous cell and are therefore blastoconidia. The systematic relationships between T. caligans and T. terrestris and other species of the genus Torula are discussed. PMID:1220860

Obituary: Elizabeth Katherine Holmes, 1973-2004  

NASA Astrophysics Data System (ADS)

Elizabeth (Beth) K. Holmes died suddenly in Pasadena on March 23, 2004, from the unexpected effects of a long-standing heart condition. She was 30 years old. At the moment of her passing, she was at her computer comparing her theoretical models on the effects of planets on the distribution of zodiacal dust with some of the first observations from the Spitzer Space Telescope. Born on June 24, 1973, in New York City, Beth was the only child of James and Barbara Holmes, who were respectively, a financial manager and a nurse and social worker. Undeterred by numerous treatments and operations to correct a congenital heart condition, Beth developed an interest in math and physics leading to her graduation from MIT in 1995 with a bachelor's degree in Physics. She entered the University of Florida shortly afterwards to begin her PhD studies under the direction of Stanley Dermott. Beth was particularly interested in the dynamics of interplanetary dust, and initially worked on secular perturbations of the zodiacal cloud: how the planets impose warping of the cloud, and how they can force the center of the cloud to be offset from the Sun. Despite the fact that Beth was primarily a theorist, she was keen to include some observing experience in her PhD education. She recently completed an observing program with Harold Butner at the Steward and Palomar Observatories looking for submillimeter and mid-infrared emission around nearby main-sequence stars - a signpost of planetary formation. The results were published last year in the Astronomical Journal. Beth's PhD thesis work, some results of which were recently published in the Astrophysical Journal, focused on dust originating in the Kuiper belt and how some of this dust is expected to be spatially structured due to resonant interactions with Neptune. This phenomenon may be quite common in other planetary systems, with recent images of Epsilon Eridani perhaps providing a prime example of a Kuiper disk analog. After graduating from Florida in 2002, Beth took up a National Research Council postdoctoral position at the Jet Propulsion Laboratory with Charles Beichman and T. Velusamy with the goal of applying her theoretical knowledge of zodiacal clouds to observations from the Spitzer Space telescope. In advance of the launch of Spitzer, Beth gathered detailed information on over 150 solar type stars and carefully planned a Spitzer observing program to detect faint zodiacal signals. While waiting through numerous launch delays, she prepared models of zodiacal clouds influenced by the presence of planets to be ready when Spitzer images of stars like Vega, Upsilon Andromedae, and Fomalhaut became available. These models were presented as talks and posters at a number of conferences. Her models were a critical part of the Early Release Observations of Fomalhaut and the subsequent Spitzer paper on the possibility that a Jovian-mass planet located approximately 40 AU from the star was responsible for the structures seen in the Fomalhaut disk. The Fomalhaut paper in the special Spitzer edition of the Astrophysical Journal is dedicated to Beth's memory. Beth was an enthusiastic and cheerful colleague who made friends everywhere she worked. In addition to developing friendships and collaborations at JPL, she became a valued member of the Spitzer/MIPS instrument team at the University of Arizona. She was active on the Committee on the Status of Women in Astronomy of the American Astronomical Society, publishing an article on "The Postdoc Perspective on the Women in Astronomy II Conference" in the January 2004 issue of STATUS, the CSWA magazine, and serving as an associate editor of that magazine. She was an inspiring role model for young women in science, befriending and mentoring a number of Caltech women undergraduates, as well as making numerous appearances in K-12 classrooms for science outreach. She pursued her love of plants (cactus in particular), cats and fish, spending her spare time lovingly tending her small garden. Her friends and colleagues will remember Beth for her scienti

Charge induced closing of Dionaea muscipula Ellis trap.

In terms of bioelectrochemistry, Venus flytrap responses can be considered in three stages: stimulus perception, electrical signal transmission, and induction of mechanical and biochemical responses. When an insect touches the trigger hairs, these mechanosensors generate receptor potentials, which induce solitary waves activating the motor cells. We found that the electrical charge injected between a midrib and a lobe closes the Venus flytrap leaf by activating motor cells without mechanical stimulation of trigger hairs. The mean electrical charge required for the closure of the Venus flytrap leaf is 13.6 muC. To close the trap, electrical charge can be submitted as a single charge or applied cumulatively by small portions during a short period of time. Ion channel blocker such as Zn(2+) as well as an uncoupler CCCP, dramatically decreases the speed of the trap closing a few hours after treatment of the soil. This effect is reversible. After soil washing by distilled water, the closing time of Venus flytrap treated by CCCP or ZnCl(2) decreases back from 2-5 s to 0.3 s, but higher electrical charge is needed for trap closure. The mechanism behind closing the upper leaf of Venus flytrap is discussed. PMID:18400564

Gravity Currents: In the Environment and the Laboratory, Ellis Horwood Series in Environmental Sciences  

NASA Astrophysics Data System (ADS)

There are books and courses on experimental physics, thorough and rigorous, which contain only simple formulae and use only elementary algebra. The subject is explained in lucid and precise language, with the help of many sketches, photos, and diagrams. The book under review belongs to this genre and is in fact one of its most successful members.About half of the book is devoted to the description of a variety of natural phenomena in which gravity currents play an important role. The class of gravity currents is taken to be quite broad, to include almost any kind of quasi-horizontal motion caused by density differences. The range of natural phenomena surveyed is correspondingly great, from tidal bores through thunderstorms to the eruption of Mount St. Helens. The atmospheric examples are especially thorough and interesting. The broad panorama certainly brings home to the reader the many ways in which fluids (including fluidized rock) can move under the influence of gravity. However, not all of the examples show typical gravity behavior, nor are they all treated with equal thoroughness. The Gulf Stream is mentioned, and the variability of its position is shown in an illustration, but this is not connected with anything typical of gravity currents, nor is the important interplay between Earth rotation and such large-scale “gravity currents” (if one insists on calling them that) at all adequately explained.

Immigration: From the Founding of Virginia to the Closing of Ellis Island. An Eyewitness History.  

ERIC Educational Resources Information Center

It can be said that U.S. immigration started in 1607, when the first settlers joined the original colonists on the shores of the United States. Since then, people of every nation, ethnicity, and class have come to the United States, looking for freedom, prosperity, and stability. While originally immigrants flowed freely into the United States,…

On the mechanism underlying photosynthetic limitation upon trigger hair irritation in the carnivorous plant Venus flytrap (Dionaea muscipula Ellis).  

PubMed

Mechanical stimulation of trigger hairs on the adaxial surface of the trap of Dionaea muscipula leads to the generation of action potentials and to rapid leaf movement. After rapid closure secures the prey, the struggle against the trigger hairs results in generation of further action potentials which inhibit photosynthesis. A detailed analysis of chlorophyll a fluorescence kinetics and gas exchange measurements in response to generation of action potentials in irritated D. muscipula traps was used to determine the 'site effect' of the electrical signal-induced inhibition of photosynthesis. Irritation of trigger hairs and subsequent generation of action potentials resulted in a decrease in the effective photochemical quantum yield of photosystem II (?(PSII)) and the rate of net photosynthesis (A(N)). During the first seconds of irritation, increased excitation pressure in photosystem II (PSII) was the major contributor to the decreased ?(PSII). Within ?1?min, non-photochemical quenching (NPQ) released the excitation pressure at PSII. Measurements of the fast chlorophyll a fluorescence transient (O-J-I-P) revealed a direct impact of action potentials on the charge separation-recombination reactions in PSII, although the effect seems to be small rather than substantial. All the data presented here indicate that the main primary target of the electrical signal-induced inhibition of photosynthesis is the dark reaction, whereas the inhibition of electron transport is only a consequence of reduced carboxylation efficiency. In addition, the study also provides valuable data confirming the hypothesis that chlorophyll a fluorescence is under electrochemical control. PMID:21289078

PubMed Central

Objective: To compare the effectiveness of rational, behavioral and emotive therapy (REBT) and person-centered therapy (PCT) on self-differentiation and intimacy among divorce clients. Methods: In quasi-experimental study, 42 divorce clients (both males and females) who presented to the Counsling Center of Sanandaj, Iran were sampled. They were categorized into three groups of PCT, REBT, and control group (each group contained 14 subjects). The recovery indices (dependent variables) employed were the subject of self-differentiation and intimacy, which were measured twice before and after intervention of Differentiation of Self Inventory-2 (DSI-2) and intimacy. The therapy involved 8 one-hour sessions. It was held twice a week and therapeutic effects were traced after 8 months. Results: The results showed that REBT and PCT were effective on self-differentiation scale and intimacy. Also they were influential in recovery self-differentiation scale and intimacy follow up stage. Conclusion: REBT and PCT were effective on self-differentiation and its subscales (Emotional reactivity, “I” position, Emotional cut off and Fusion with other) and general intimacy.

Biomass assisted synthesis of alumina by Gardenia Jasminoides Ellis and their application for removal of Ni(II) from aqueous solution.  

PubMed

A simple and novel process has been proposed to synthesize alumina using gardenia extract and aluminum salts in an aqueous solution. The alumina sample notated as "bio-Al?O?" was characterized by X-ray diffraction (XRD) and nitrogen adsorption-desorption experiment. The results indicated that the existence of the gardenia biomass enlarged the surface area of alumina and reached 256 m(2)/g. The thermo gravimetric (TG), X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FTIR) results showed that gardenia biomass bound to the surface of the alumina has substantially improved the adsorption capacity of Ni(II) and the adsorption behavior of nickel ion was related to the biomass functional groups. The results of three adsorption-desorption cycles showed that the bio-Al?O? using as the adsorbent for Ni(II) was relatively stable. The kinetic of the Ni(II) adsorption by the bio-Al?O? followed pseudo-second-order equation. Langmuir and Freundlich isotherm models were applied to analyze the experimental data and the result demonstrated that the adsorption isotherms followed Langmuir isotherm model. PMID:23892172

EDITORIAL: Focus on Dark Matter and Particle Physics  

NASA Astrophysics Data System (ADS)

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

Some similarities between these deaths and recent near-death experience (NDE) accounts are that the characters experience various kinds of distancing from their bodies, light and darkness play a role, and two of

Conversion electron spectroscopy at IGISOL  

NASA Astrophysics Data System (ADS)

Conversion elecron spectroscopy has been an important part of the nuclear spectrocopy research at the Department of Physics of the University of Jyväskylä since the commissioning of the first cyclotron in the mid 1970s. At the IGISOL facility a specialiced conversion electron spectrometer ELLI was developed in the late 1980s. The first results with ELLI were obtained using the beams from the old MC-20 cyclotron to study newly discovered isotopes of refractory fission products. In the present K130 cyclotron laboratory ELLI has been utilized in many decay-spectroscopy experiments both neutron-deficient and neutron-rich side of the valley of stability. In the early 2000s the new JYFLTRAP ion trap system overthrew ELLI from its permanent place in the IGISOL beamline. Conversion electron spectroscopy has continued with the new Penning trap that has been used in in-trap electron spectroscopy tests and post-trap electron spectroscopy is foreseen.

Interactions between a group of Golden Eagles and a herd of North American elk  

USGS Publications Warehouse

Raptors are generally considered solitary predators (Schoener 1969), but occasionally they interact socially (Brown and Amadon 1968). Certain raptor species (e.g., Swallow-tailed Kites [Elanoides forficatus] and Swainson's Hawks [Buteo swainsoni]) concentrate in aggregations in response to localized, abundant food sources (Ellis et al. 1993). Many raptor species engage in group hunting (Ellis et al. 1993), and social foraging is a routine strategy for some species (e.g., Harris's Hawks [Parabuteo unicinctus]; Bednarz 1988, Ellis et al. 1993]. Raptors generally engage in group hunting to pursue elusive or large prey (Ellis et al. 1993). Occasionally individuals of conspecific raptors engage in play as a group sometimes involving chases of prey species (Palmer 1988). In this letter, we report interactions between a large group of Golden Eagles and a herd of adult and juvenile Rocky Mountain elk (Cervus canadensis nelsoni) in late autumn.

It's Just Stress, Right? A Case Study on the Endocrine System  

NSDL National Science Digital Library

Ellie is a struggling college student on the brink of failing her physiology course; not surprisingly, she exhibits many classic signs of stress. However, a visit to the health clinic reveals that she may be suffering from more than just stress. In this interrupted case, students first read about Ellie’s signs and symptoms and use a series of guided questions to make predictions about her test results and diagnosis. After Ellie receives her diagnosis, students must then explain the test results based on their knowledge of the function and regulation of the thyroid gland, and investigate various options for treatment. Designed for a two-semester undergraduate anatomy and physiology course, the case could be adapted for use in an undergraduate physiology or endocrinology course.

Signed magnification sums for general spherical lenses  

NASA Astrophysics Data System (ADS)

It is well known that the sum of signed magnifications is invariant for mass lens systems. In this paper, we discuss the signed magnification sums of general spherical lens models, including the singular isothermal sphere, the Schwarzschild lens, and the Ellis wormhole, the last of which is an example of the traversable wormholes of the Morris-Thorne class. We show that the signed magnification sums are a very useful tool to distinguish exotic lens objects. For example, we show that one can distinguish the Ellis wormholes from the Schwarzschild lens with the signed magnification sums.

Comments on “the OZI rule does not apply to baryons”  

NASA Astrophysics Data System (ADS)

We demonstrate that the arguments made by Ellis, Gabathuler and Karliner that meson-baryon couplings could evade the OZI rule are irrelevant to the arguments we have made before. This is so since even if we assume that meson-baryon couplings can violate OZI, we clearly demonstrate that the coupling involved in our ?-p? ??n is ??? ?? which does not involve meson-baryon couplings.Thus our arguments that the g T(2010), g T?(2300), g T?(2340) are naturally explained in the context of QCD by the hypothesis that one to three glueballs are produced in the intermediate state are not affected by arguments made by Ellis et al.

Regulating Providers' Reimbursement in a Mixed Market for Health Care  

Microsoft Academic Search

Hospitals can be reimbursed for their costs in many ways. Several authors have investigated the effects of these reimbursement rules on physician incentives and, therefore, on the quantity of services provided to patients. A form of (linear) cost-sharing tends to emerge as the socially efficient reimbursement policy. The authors present a model of hospital reimbursement, based on Ellis and McGuire

Dry season conditions determine wet season water use in the wet-tropical savannas of northern Australia.  

PubMed

Daily and seasonal patterns of transpiration were measured in evergreen eucalypt trees growing at a wet (Darwin), intermediate (Katherine) and dry site (Newcastle Waters) along a steep rainfall gradient in a north Australian savanna. Relationships between tree size and tree water use were also determined. Diameter at breast height (DBH) was an excellent predictor of sapwood area in the five eucalypt species sampled along the rainfall gradient. A single relationship existed for all species at all sites. Mean daily water use was also correlated to DBH in both wet and dry seasons. There were no significant differences in the relationship between DBH and tree water use at Darwin or Katherine. Among the sites, tree water use was lowest at Newcastle Waters at all DBHs. The relationship between DBH and tree leaf area was similar between species and locations, but the slope of the relationship was less at the end of the dry season than at the end of the wet season at all locations. There was a strong relationship between sapwood area and leaf area that was similar at all sites along the gradient. Transpiration rates were significantly lower in trees at the driest site than at the other sites, but there were no significant differences in transpiration rates between trees growing at Darwin and Katherine. Transpiration rates did not vary significantly between seasons at any site. At all sites, there was only a 10% decline in water use per tree between the wet and dry seasons. A monthly aridity index (pan evaporation/rainfall) and predawn leaf water potential showed strong seasonal patterns. It is proposed that dry season conditions exert control on tree water use during the wet season, possibly through an effect on xylem structure. PMID:12651484

They will also consider the environmental effects of the different types of land use. Students will assume the role of community planning engineers and will create a future plan for their community. (Note: Teachers will need to check out the following book from the local or school library: Durell, Ann, Craighead George, Jean, and Paterson, Katherine. The Big Book For Our Planet, New York: Dutton Children's Books, 1993).

Mass extinctions and supernova explosions.  

PubMed Central

In a recent contribution to this journal Ellis and Schramm [Ellis, J. & Schramm, D. N. (1995) Proc. Natl. Acad. Sci. USA 92, 235-238] claim that supernova explosions can cause massive biological extinctions as a result of strongly enhanced stratospheric NOx (NO + NO2) production by accompanying galactic cosmic rays. They suggested that these NOx productions which would last over several centuries and occur once every few hundred million years would result in ozone depletions of about 95%, leading to vastly increased levels of biologically damaging solar ultraviolet radiation. Our detailed model calculations show, however, substantially smaller ozone depletions ranging from at most 60% at high latitudes to below 20% at the equator.

On the OZI rule for baryons  

NASA Astrophysics Data System (ADS)

Ellis, Gabathuler and Karliner [Phys. Lett. B 217 (1989) 173] have recently proposed on theoretical grounds that the Okubo-Zweig-Iizuka (OZI) rule does not apply to baryonic vertices because baryons contain a significant number of strange quark-antiquark pairs, and they claim some phenomological support for this proposal. In the light of this, the excellent data on backward meson production is critically re-examined. We find some evidence for OZI-evading couplings for the case of the ?, and put bounds on any OZI-violating couplings of the f2? (1525). The violations found do not follow the pattern predicted by Ellis et al. and are also so small as to make their significance questionable. We also re-examine the data on the related question of Z* (exotic baryon) exchange.

QCD FITS to Diffraction  

NASA Astrophysics Data System (ADS)

The most recent H1 and ZEUS data for diffractive structure functions are analyzed under three different theoretical approaches. This includes the Pomeron Structure Function (PSF) framework, Bartels-Ellis-Kowalski-Wüsthoff (BEKW) color dipole approach and the Golec-Biernat-Wüsthoff (GBW) saturation model. The models are shown to successfully fit the set of combined data. Conceptual differences between the models are discussed and, as an example, the prediction for the longitudinal diffractive structure function is presented.

I consider the Newtonian-like, timelike congruences of Ellis and van Elst, which is to say timelike congruences which are both twist-free and shear-free. I find all such congruences in flat space and give an algorithm for recognizing candidates for such congruences in curved space. I find the metric form which is necessary and sufficient to admit infinitely many distinct such congruences. In particular, the spherically symmetric dust cosmologies of Bondi are seen to admit infinitely many.

We consider the problem of large deviations for a two-time-scale reflected diffusion process, possibly with delays in the dynamical terms. The Dupuis-Ellis weak convergence approach is used. It is perhaps the most intuitive and simplest for the problems of concern. The results have applications to the problem of approximating optimal controls for two-time-scale systems via use of the averaged equation.

Cognitions as determinants of (mal)adaptive emotions and emotionally intelligent behavior in an organizational context.  

PubMed

This study applies the theoretical concepts of Rational Emotive Behavior Therapy (REBT; Ellis, 1962, 1994) to the analysis of functional and dysfunctional behaviour and emotions in the workplace and tests central assumptions of REBT in an organizational setting. We argue that Ellis' appraisal theory of emotion sheds light on some of the cognitive and emotional antecedents of emotional intelligence and emotionally intelligent behaviour. In an extension of REBT, we posit that adaptive emotions resulting from rational cognitions reflect more emotional intelligence than maladaptive emotions which result from irrational cognitions, because the former lead to functional behaviour. We hypothesize that semantically similar emotions (e.g. annoyance and rage) lead to different behavioural reactions and have a different functionality in an organizational context. The results of scenario experiments using organizational vignettes confirm the central assumptions of Ellis' appraisal theory and support our hypotheses of a correspondence between adaptive emotions and emotionally intelligent behaviour. Additionally, we find evidence that irrational job-related attitudes result in reduced work (but not life) satisfaction. PMID:17295975

Freud's Rat Man from the perspective of an early-life variant of the Oedipus complex.  

PubMed

In the spirit of Freud's invitation to other investigators to elaborate on his "Notes Upon a Case of Obsessional Neurosis" (1909), the author offers additional and differing views on the case of the Rat Man (Dr. Ernst Langer). These views have been informed by the evolution of psychoanalysis over the past 100 years, especially by the perspective provided by an early-life variant on the Oedipus complex (Osman 2000). The author postulates that an important reason for the happy conclusion of this analysis, surprising for its brevity, was that it expedited a mourning process that released a primitive bond to the patient's father, and also, in doing so, facilitated the emergence of a less encumbered and more individuated identity. While accomplishing this, constricting bonds to his late sister Katherine and to his mother were loosened as well. PMID:19685813

Field et Al. Redux.

On 12 February 1988 (by coincidence Charles Darwin's birthday), a paper published in Science by Katherine Field, Rudy Raff, and colleagues presented the first credible molecular analysis of metazoan phylogeny based on sequences from the small subunit ribosomal RNA gene (SSU). Here I examine the main conclusions reached in this manuscript. I reconstitute their dataset and, by recompiling software available in 1988, I consider how they might have achieved a more accurate tree. I show how three common methods to avoid systematic error - more data, careful taxon sampling and superior models of evolution - overcome the errors that exist in the original paper. This approach illustrates the basis of some of the major advances of the past 25 years resulting in our current understanding of animal phylogeny. PMID:23398689

The University of Utah Department of physics and Astronomy recently completed construction of the Willard L. Eccles Observatory, a new facility on the edge of the Great Basin desert in western Utah. Located between Las Vegas and Salt Lake City, the site was chosen after careful consideration of climate, light pollution, seeing quality, and available infrastructure. The observatory is located on a prominent peak at an altitude of 9551 feet and houses a 0.8 meter optical telescope from DFM Engineering. The first images taken with the telescope have produced sub-arcsecond seeing and minimal sky background as would be expected for this remote site. We will present a description of the observatory and a preliminary characterization of the site. The construction of this observatory was made possible by the generous support of the Willard L. Eccles Foundation and the Katherine W. and Ezekiel R. Dumke, Jr. Foundation.

Field et al. Redux.  

PubMed Central

On 12 February 1988 (by coincidence Charles Darwin’s birthday), a paper published in Science by Katherine Field, Rudy Raff, and colleagues presented the first credible molecular analysis of metazoan phylogeny based on sequences from the small subunit ribosomal RNA gene (SSU). Here I examine the main conclusions reached in this manuscript. I reconstitute their dataset and, by recompiling software available in 1988, I consider how they might have achieved a more accurate tree. I show how three common methods to avoid systematic error - more data, careful taxon sampling and superior models of evolution - overcome the errors that exist in the original paper. This approach illustrates the basis of some of the major advances of the past 25 years resulting in our current understanding of animal phylogeny.

Life in Elizabethan England: A Compendium of Common Knowledge, 1558-1603  

NSDL National Science Digital Library

Compiled by Maggie Pierce Secara, who has for twelve years acted as the Countess of Southampton at the Renaissance Pleasure Faire, and designed by Paula Katherine Marmor, this site offers fragments from the social history of Elizabethan England. The compendium bills itself as a sort of primer for the tidbits of life that should be common knowledge to writers or (re-en)actors "who work and play in the 16th Century on a regular basis." If you keep bees, for example, you should know that bees love gossip, and it's good luck to tell them all of the latest news. Just about anyone with an interest in social history will find some of the "fact bites" here intriguing. The useful appendices include Maps & Plans, Bibliography, The Tudor Succession, and a list of Related Sites. The compendium can be browsed or searched online or downloaded as an MS Word or .pdf document.

A redescription of Protospirura muricola Gedoelst, 1916 (Nematoda: Spiruridae), a parasite of murid rodents.  

PubMed

The spirurid nematode Protospirura muricola Gedoelst, 1916 is redescribed from Acomys dimidiatus (Desmarest) from the St Katherine Protectorate, Sinai, Egypt. Egyptian material closely resembled specimens of P. muricola from African mammals re-examined in this study, as well as conforming to published reports of this species. P. muricola with two denticles on each lateral lobe of the pseudolabia and six pairs of postanal papillae is closest to P. pseudomuris Yokohata & Abe, 1989, but can be readily distinguished in having the right spicule shorter than the left. The significance of the characteristics of the head and mouth, and of the male spicules, in characterising Protospirura Seurat, 1914 is evaluated. P. muricola, an African parasite of rodents, appears to have spread globally with synanthropic rat final hosts and possibly with the cosmopolitan dermapteran intermediate host Leucophaea maderae (Fabr.).

Trachoma elimination in remote Indigenous Northern Territory communities: baseline health-promotion study.  

PubMed

Identify trachoma knowledge, attitudes and practice of staff in clinics, schools and community workplace settings to optimise trachoma-elimination health-promotion programs in the Katherine West Health Board region of the Northern Territory. Prior to the introduction of a suite of health promotion resources the Indigenous Eye Health Unit and Katherine West Health Board conducted a baseline survey of open, multi-choice and closed questions regarding knowledge, attitudes and practices in relation to trachoma with 72 staff members over a 6-month period in 2010-11. Data were analysed for differences between settings. Two significant barriers and one enabling factor were identified. One in five staff members in clinics and 29% of staff members in schools were unaware they lived and worked in a trachoma-endemic area. One-third of school staff and 38% of clinic staff considered it normal for children to have dirty faces. However, the majority of participants felt comfortable talking about hygiene issues with others. The presence of dirty faces in young Indigenous children underpins the continuing prevalence of trachoma. Increasing the awareness of the health effects of children's nasal and ocular secretions and changing community acceptance of dirty faces as the norm will reduce the risk of trachoma and other childhood infections. Staff in clinics, schools and community work settings can play a role in trachoma elimination by actively encouraging clean faces whenever they are dirty and by including face washing in holistic hygiene and health education. Staff in schools may need additional support. Trachoma-elimination health promotion should increase awareness of trachoma prevalence and encourage all who work and live in remote Indigenous communities to take action to promote facial cleanliness and good hygiene practices.

Coronary artery perforation during percutaneous coronary intervention: a systematic review and meta-analysis.  

PubMed

Numerous studies have examined the incidence, predictors, outcomes, and management strategies of coronary artery perforation (CAP). Individually, these studies have been inconclusive because of their limited sample sizes and/or single-centre designs. We conducted a systematic review and meta-analysis of studies pertaining to CAP in order to estimate its incidence and outcomes and to critically review its risk factors and treatment. We systematically searched the literature to identify all registry studies investigating CAP. Data were pooled by means of the random-effects model. In 16 studies involving 197,061 percutaneous coronary interventions, the pooled incidence of CAP was 0.43% (95% confidence interval, 0.35%-0.52%). The most reproducible risk factors were treatment of complex lesions and use of atheroablative devices. A variety of major management strategies for CAP were used, in particular, observation, heparin reversal, prolonged balloon inflation, covered stent implantation, pericardiocentesis, and surgery. In a hierarchical Bayesian random-effects model, the pooled tamponade rates were 0.4% (95% credible interval [CrI], 0.0%-5.7%), 3.3% (95% CrI, 0.0%-11.4%), and 45.7% (95% CrI, 34.9%-57.5%) for patients with Ellis class I, II, and III CAP, respectively. Pooled mortality rates were 0.3% (95% CrI, 0.0%-4.4%), 0.4% (95% CrI, 0.0%-2.8%), and 21.2% (95% CrI, 12.0%-31.4%) for patients with Ellis class I, II, and III CAP respectively. CAP complicating percutaneous coronary intervention is rare, and its morbidity and mortality vary directly with Ellis classification. Management discrepancies highlight the need to establish a uniform treatment paradigm for CAP. PMID:21862280

Electromagnetic field properties in the vicinity of a massive wormhole  

NASA Astrophysics Data System (ADS)

It is proved that not only massless but also traversable massive wormholes can have electromagnetic "hair." An analysis is also presented of the passage from a traversable wormhole to the limit of a Reissner-Nordström black hole, with the corresponding disappearance of "hair." A general method is developed for solving stationary axisymmetric Maxwell's equations in the field of a massive, spherically symmetric wormhole. As a particular example of application of the method, a solution is found to the axisymmetric magnetostatic problem for a current loop in the field of the Bronnikov-Ellis-Morris-Thorne wormhole.

Growth and scaling in anisotropic spinodal decomposition  

NASA Astrophysics Data System (ADS)

We studied phase separation in a particle interacting system under a large drive along x. We here identify the basic growth mechanisms, and demonstrate time self-similarity, finite-size scaling, as well as other interesting features of both the structure factor and the scaling function. We also show that, at late t in two dimensions, there is a unique t-dependent length increasing elly(t) ~ t1/3 for macroscopic systems. Our results, which follow as a direct consequence of the underlying anisotropy, may characterize a class of nonequilibrium situations.

Biologically Closed Electrical Circuits in Venus Flytrap[OA  

PubMed Central

The Venus flytrap (Dionaea muscipula Ellis) is a marvel of plant electrical, mechanical, and biochemical engineering. The rapid closure of the Venus flytrap upper leaf in about 0.1 s is one of the fastest movements in the plant kingdom. We found earlier that the electrical stimulus between a midrib and a lobe closes the Venus flytrap upper leaf without mechanical stimulation of trigger hairs. The Venus flytrap can accumulate small subthreshold charges and, when the threshold value is reached, the trap closes. Here, we investigated the electrical properties of the upper leaf of the Venus flytrap and proposed the equivalent electrical circuit in agreement with the experimental data.

Access to the article is free, however registration and sign-in are required. Although the signal transduction pathways emanating from G protein-coupled receptors in animal cells are well established, their counterparts in plant cells are still a mystery. In a Perspective, Ellis and Miles discuss new findings (Ullah et al., Wang et al.) revealing that the G-protein alpha subunit may be involved both in the hormone-activated signal transduction pathways regulating cell division and in the regulation of the opening and closing of the apertures (stomata) in leaf guard cells.

Non-syndrome patient with bilateral supernumerary teeth: Case report and 9-year follow-up  

PubMed Central

The presence of supernumerary teeth, also known as hyperdontia, is the condition of having teeth in addition to the regular number of teeth. The occurrence of multiple supernumerary teeth is often found in association with syndromes such as Gardner syndrome, Anderson-Fabry disease, Ellis-van Creveld syndrome, Ehlers-Danlos syndrome, incontinentia pigmenti, and Tricho-rhino-phalangeal syndrome. Only a few examples of nonsyndromic multiple supernumerary teeth have been reported in literature. In this report, we present the unusual case and 9-year follow up of a non-syndrome female patient with bilateral supernumerary teeth that occurred with an interval of several years.

Spin-structure function of the neutron ({sup 3}He): SLAC results  

SciTech Connect

A first measurement of the longitudinal asymmetry of deep-inelastic scattering of polarized electrons from a polarized {sup 3}He target at energies ranging from 19 to 26 GeV has been performed at SLAC. The spin-structure function of the neutron g{sub 1}{sup n} has been extracted from the measured asymmetries allowing for a test of the Ellis-Jaffe and Bjorken sum rules. The Quark Parton Model (QPM) interpretation of the nucleon spin-structure function is examined in light of the new results.

Fast pressure probe measurements of a high-velocity plasma plume  

NASA Astrophysics Data System (ADS)

This article reports measurements of stagnation pressure on a contoured coaxial gun, now installed at the Maryland Centrifugal Experiment [R. Ellis et al., Phys. Plasmas 12, 055704 (2005)]. The impact of the plasma on the stationary probe is consistent with adiabatic compression and supersonic flow. Measured pressure signals are consistent with a shock traveling at 110 km/s and a following flow with speed of 90 km/s. At late times, the pressure profile is consistent with an adiabatically expanding plasma that fills the vacuum chamber.

Example of a stable wormhole in general relativity  

NASA Astrophysics Data System (ADS)

We study a static, spherically symmetric wormhole model whose metric coincides with that of the so-called Ellis wormhole but the material source of gravity consists of a perfect fluid with negative density and a source-free radial electric or magnetic field. For a certain class of fluid equations of state, it has been shown that this wormhole model is linearly stable under both spherically symmetric perturbations and axial perturbations of arbitrary multipolarity. A similar behavior is predicted for polar nonspherical perturbations. It thus seems to be the first example of a stable wormhole model in the framework of general relativity (at least without invoking phantom thin shells as wormhole sources).

Wormholes threaded by chiral fields  

NASA Astrophysics Data System (ADS)

We consider Lorentzian wormholes with a phantom field and chiral matter fields. The chiral fields are described by the nonlinear sigma model with or without a Skyrme term. When the gravitational coupling of the chiral fields is increased, the wormhole geometry changes. The single throat is replaced by a double throat with a belly in between. For a maximal value of the coupling, the radii of both throats reach zero. Then the interior part pinches off, leaving a closed universe and two (asymptotically) flat spaces. A stability analysis shows that all wormholes threaded by chiral fields inherit the instability of the Ellis wormhole.

Wormholes in higher dimensional space-time: Exact solutions and their linear stability analysis  

NASA Astrophysics Data System (ADS)

We derive the simplest traversable wormhole solutions in n-dimensional general relativity, assuming static and spherically symmetric space-time with a ghost scalar field. This is the generalization of the Ellis solution (or the so-called Morris-Thorne’s traversable wormhole) into a higher dimension. We also study their stability using linear perturbation analysis. We obtain the master equation for the perturbed gauge-invariant variable and search their eigenvalues. Our analysis shows that all higher dimensional wormholes have an unstable mode against the perturbations with which the throat radius is changed.

Metastability within the generalized canonical ensemble  

NASA Astrophysics Data System (ADS)

We discuss a property of our recently introduced generalized canonical ensemble [M. Costeniuc, R.S. Ellis, H. Touchette, B. Turkington, The generalized canonical ensemble and its universal equivalence with the microcanonical ensemble, J. Stat. Phys. 119 (2005) 1283]. We show that this ensemble can be used to transform metastable or unstable (nonequilibrium) states of the standard canonical ensemble into stable (equilibrium) states within the generalized canonical ensemble. Equilibrium calculations within the generalized canonical ensemble can thus be used to obtain information about nonequilibrium states in the canonical ensemble.

Biologically closed electrical circuits in venus flytrap.  

PubMed

The Venus flytrap (Dionaea muscipula Ellis) is a marvel of plant electrical, mechanical, and biochemical engineering. The rapid closure of the Venus flytrap upper leaf in about 0.1 s is one of the fastest movements in the plant kingdom. We found earlier that the electrical stimulus between a midrib and a lobe closes the Venus flytrap upper leaf without mechanical stimulation of trigger hairs. The Venus flytrap can accumulate small subthreshold charges and, when the threshold value is reached, the trap closes. Here, we investigated the electrical properties of the upper leaf of the Venus flytrap and proposed the equivalent electrical circuit in agreement with the experimental data. PMID:19211696

[Ancient mental healing and cognitive behavior therapy in comparison].  

PubMed

Although cognitive-behavior therapy (CBT) is a relatively new psychotherapeutic approach, the theoretical antecedents actually date back two thousand years, to the period of the hellenistic philosophers. The Stoic Epictetus is often acknowledged as the main philosophical father of CBT and especially of rational-emotive therapy (RET). Beck and Ellis frequently noted that they have drawn upon the writings of the ancient philosophers in developing their psychotherapeutic techniques. This paper reviews some implications of hellenistic philosophy for CBT. We like to show that the teachings of the ancient 'healer of souls' are remarkably consistent with the current theoretical framework and techniques of CBT. PMID:3073604

In this paper the drag-out problem for shear-thinning liquids at variable inclination angles is considered. For this free boundary problem dimension-reduced lubrication equations are derived for the most commonly used viscosity models, namely, the power-law, Ellis, and Carreau model. For the resulting lubrication models a system of ordinary differential equations governing the steady state solutions is obtained. Phase plane analysis is used to characterize the type of possible steady state solutions and their dependence on the rheological parameters. PMID:17930341

NSDL National Science Digital Library

Access to the article is free, however registration and sign-in are required. After proteins are made, they must be folded into their final structure. In a report in this week's issue of Science, Frydman and Hartl, on page 1497, compare how molecular chaperones (proteins that assist folding) affect folding of proteins as they are synthesized from ribosomes and proteins that have been artificially denatured. In his Perspective, Ellis discusses why the differences that are found tell us something about how chaperones really work in the cell.

Astrophysics of Bertrand space-times  

NASA Astrophysics Data System (ADS)

We construct a model for galactic dark matter that arises as a solution of Einstein gravity and is a Bertrand space-time matched with an external Schwarzschild metric. This model can explain galactic rotation curves. Further, we study gravitational lensing in these space-times, and in particular we consider Einstein rings using the strong lensing formalism of Virbhadra and Ellis. Our results are in good agreement with observational data and indicate that under certain conditions, gravitational lensing effects from galactic dark matter may be similar to that from Schwarzschild backgrounds.

The Maple package NPTOOLS; a symbolic algebra package for tetrad formalisms in general relativity  

NASA Astrophysics Data System (ADS)

In this paper, we present and discuss the NPTOOLS package written for the computer algebra system Maple. The package contains the main routines "nulltran", "inv", "nullor", "ornull" and "pptype". The routine "nulltran" is an implementation of the 6-parameter Lorentz group in the Newman-Penrose (null tetrad) formalism, and "inv" checks for invariance of equations under subgroups of the Lorentz group. The routines "nullor" and "ornull" provide a translation between the Newman-Penrose quantities associated with the null tetrad and the orthonormal tetrad quantities associated with the Ellis-MacCallum formalism. Finally, "pptype" determines the Petrov-Pleba?ski type of the Ricci tensor.

Probing violation of quantum mechanics in the K0-(bar K)0 system  

NASA Astrophysics Data System (ADS)

I present a recent study made in collaboration with M.E. Peskin, on the time dependence of a kaon beam propagating according to the '(alpha)(beta)(gamma)' generalization of quantum mechanics due to Ellis, Hagelin, Nanopoulos and Srednicki, in which CP- and CPT-violating signatures arise from the evolution of pure states to mixed states. The magnitude of two of its parameters (beta) and (gamma) are constrained on the basis of existing experimental data. New facilities such as (phi)-Factories are shown to be particularly adequate to study this generalization from quantum mechanics and to disentangle its parameters from other CPT violating perturbations of the kaon system.

Space-Time Fluctuations Induced by D-Branes and Their Effects on Neutrino Oscillations  

NASA Astrophysics Data System (ADS)

Neutrino oscillations are analyzed in the Ellis-Mavromatos-Nanopoulos-Volkov (ENMV) model, where the quantum gravitational fluctuations of the space-time background are described by virtual D branes. Such fluctuations may induce neutrino oscillations if a violation of the equivalence principle or a tiny violation of the Lorentz invariance is imposed. In this framework, the oscillation length of neutrinos turns out to be proportional to E -2 M, where E is the neutrino energy and M is the energy which is the scale characterizing the topological fluctuations in the vacuum.

String-loop corrections to effective action and black-hole instabilities  

NASA Astrophysics Data System (ADS)

Following the ideas of Ellis, Mavromatos and Nanopoulos, to account for instability of 2D black-hole solution, we discuss possible imaginary string-loop corrections to the coefficient at the Einstein term in string effective action. In closed bosonic string theory, such corrections appear because of the tachyon contribution to the integration measure over the moduli. In superstring theory (in critical as well as in non-critical dimensions), no one-string-loop complex corrections to the Einstein term are generated and the mechanism for generating black-hole instabilities proposed above fails.

We present a formalism for computing time-dependent asymmetries in this model and show that present data constrains its parameters significantly. In the future, this model will be put to very stringent tests at a ø-factory.

Electrical memory in Venus flytrap.  

PubMed

Electrical signaling, memory and rapid closure of the carnivorous plant Dionaea muscipula Ellis (Venus flytrap) have been attracting the attention of researchers since the XIX century. The electrical stimulus between a midrib and a lobe closes the Venus flytrap upper leaf in 0.3 s without mechanical stimulation of trigger hairs. Here we developed a new method for direct measurements of the exact electrical charge utilized by the D. muscipula Ellis to facilitate the trap closing and investigated electrical short memory in the Venus flytrap. As soon as the 8 microC charge for a small trap or a 9 microC charge for a large trap is transmitted between a lobe and midrib from the external capacitor, the trap starts to close at room temperature. At temperatures 28-36 degrees C a smaller electrical charge of 4.1 microC is required to close the trap of the D. muscipula. The cumulative character of electrical stimuli points to the existence of short-term electrical memory in the Venus flytrap. We also found sensory memory in the Venus flytrap. When one sustained mechanical stimulus was applied to only one trigger hair, the trap closed in a few seconds. PMID:19356999

Testing two mechanisms by which rational and irrational beliefs may affect the functionality of inferences.  

PubMed

This article describes a role playing experiment that examined the sufficiency hypothesis of Rational Emotive Behaviour Therapy (REBT). This proposition states that it is sufficient for rational and irrational beliefs to refer to preferences and musts, respectively, if those beliefs are to affect the functionality of inferences (FI). Consistent with the REBT literature (e.g. Dryden, 1994; Dryden & Ellis, 1988; Palmer, Dryden, Ellis & Yapp, 1995) results from this experiment showed that rational and irrational beliefs, as defined by REBT, do affect FI. Specifically, results showed that people who hold a rational belief form inferences that are significantly more functional than those that are formed by people who hold an irrational belief. Contrary to REBT theory, the sufficiency hypothesis was not supported. Thus, results indicated that it is not sufficient for rational and irrational beliefs to refer to preferences and musts, respectively, if those beliefs are to affect the FI. It appears, then, that preferences and musts are not sufficient mechanisms by which rational and irrational beliefs, respectively, affect the FI. Psychotherapeutic implications of these findings are considered. PMID:10616137

Coherent reverberation model based on adiabatic normal mode theory in a range dependent shallow water environment  

NASA Astrophysics Data System (ADS)

Ocean reverberation in shallow water is often the predominant background interference in active sonar applications. It is still an open problem in underwater acoustics. In recent years, an oscillation phenomenon of the reverberation intensity, due to the interference of the normal modes, has been observed in many experiments. A coherent reverberation theory has been developed and used to explain this oscillation phenomenon [F. Li et al., Journal of Sound and Vibration, 252(3), 457-468, 2002]. However, the published coherent reverberation theory is for the range independent environment. Following the derivations by F. Li and Ellis [D. D. Ellis, J. Acoust. Soc. Am., 97(5), 2804-2814, 1995], a general reverberation model based on the adiabatic normal mode theory in a range dependent shallow water environment is presented. From this theory the coherent or incoherent reverberation field caused by sediment inhomogeneity and surface roughness can be predicted. Observations of reverberation from the 2001 Asian Sea International Acoustic Experiment (ASIAEX) in the East China Sea are used to test the model. Model/data comparison shows that the coherent reverberation model can predict the experimental oscillation phenomenon of reverberation intensity and the vertical correlation of reverberation very well.

The Warrens and other pioneering clinician pathologists of the Massachusetts General Hospital during its early years: an appreciation on the 200th anniversary of the hospital founding.  

PubMed

To celebrate the bicentennial of the 1811 charter to establish the Massachusetts General Hospital, we tell the stories of the physicians and surgeons of the hospital who practiced pathology until the discipline was more firmly established with the recruitment of James Homer Wright who became the first full-time pathologist at the hospital in 1896. One of the two co-founders of the hospital, John Collins Warren (famed primarily for being the surgeon at the first public demonstration of ether anesthesia) had a major interest in pathology; he published a book focused on gross pathology (1837) and began the important specimen collection subsequently known as the Warren Anatomical Museum at Harvard Medical School (HMS). An early physician, John Barnard Swett Jackson, became the first professor of pathology in the United States (1847) and was a noted collector whose specimens were added to the Warren Museum. Dr Jackson showed no interest in microscopy when it became available, but microscopy was promoted from circa the late 1840s at Harvard and likely at the hospital by Oliver Wendell Holmes, the famed essayist who was on the staff of the hospital and faculty at the medical school. Microscopy was probably first used at the Hospital with any frequency on examination of fluids by the first officially designated 'Microscopist,' John Bacon Jr, in 1851, and after the mid-1850s by Calvin Ellis on anatomic specimens; Ellis went on to pioneering reform of the HMS curriculum. Reginald Heber Fitz succeeded Ellis in 1871 and was the first to be officially designated as 'Pathologist' at the hospital. Fitz is remembered for two major contributions: his paper showing the nature of, and potential surgical cure for, the disease that he termed 'appendicitis'; and his description of acute pancreatitis. With the microscope now firmly entrenched and with the increase in surgery after Fitz's work on appendicitis, surgical pathology grew quickly. J Collins Warren, the grandson of the co-founder, had a major interest in pathology and in 1895 published an impressive volume entitled 'Surgical Pathology and Therapeutics.' Dr Warren had a major interest in breast disease and was a pioneer of needle biopsy in the evaluation of breast masses. In 1888, William Fiske Whitney joined the staff of the hospital and spent his nearly 30-year career practicing primarily as a surgical pathologist, making particular innovations in intraoperative consultation. The contributions of these individuals brought the field from a gross pathology-oriented discipline mostly oriented around teaching to a microscopy-dependent practice integral to patient care, and hence set the stage for the formal founding of the Pathology department in 1896.

Women in the U.S. Postal System  

NSDL National Science Digital Library

Since the United States Post Office was established in the late 18th century, women have struggled to be recognized within its ranks. One of the earliest instances involving such a situation was when Mary Katherine Goddard petitioned none other than President George Washington after having been removed from office because of her gender. This intriguing online exhibit created by the National Postal Museum takes a close look at the role that women have played in this American institution. Visitors can click on the "Women in Postal History" section to read a series of historical essays which explore topics that include women in postal folklore and postal women in the early republic. The "Women Today" area provides a short essay on the recent history of women's involvement in the Post Office. The final section, "In their Own Words" allows users to listen to excerpts from oral histories conducted with female employees. Some of the subjects covered here include the work environment, promotions, family life, and working while pregnant.

The practical application of narrative medicine at Mayo Clinic: imagining the scaffold of a worthy house.  

PubMed

American health care institutions increasingly recognize narrative medicine as a means to developing quality patient care. More commonly applied in health care professional development settings, narrative medicine is less overtly employed with patient populations. In this article, we describe the application of various narrative practices in the patient care and medical education programs of a major health care center in Minnesota. We discuss the impact of these programs on their participants in relation to the evidence based in current scholarship. Further, we examine narrative externalization of illness in Katherine Butler Hathaway's disability memoir "The Little Locksmith," a text which implicates the work of metaphor-making as a transformative step in healing. While several reports demonstrate that patients can find creative writing during times of illness to be therapeutic, there are many for whom the practice is problematic or unattractive, obstacles to practice implementation that the authors discuss. However, based on the experience of our institution, for health care institutions seeking to build a legacy of leadership in empathic patient care, narrative-employed in mentoring physicians in training and in establishing strong, dialogic relationships with patients and colleagues-should serve as a central strategy, or scaffold.

Moral Combat in An Enemy of the People: Public Health versus Private Interests  

PubMed Central

Dr Thomas Stockmann, the protagonist of Ibsen's play, An Enemy of the People, discovers a serious health threat in the Baths of his Norwegian town. The Baths have been marketed as a health resort to lure visitors. Dr Stockmann alerts officials about the problem and assumes that they will close the Baths until it is corrected. He is met with fierce resistance, however. His brother, the town's mayor, favors keeping the Baths open and correcting the problem gradually. He advances multiple arguments that appeal to the economic interests of the town and Thomas's role-related obligation as a citizen. His wife, Katherine, wants him to cooperate with the mayor. She marshals several arguments that appeal to his obligations as a father. This paper reconstructs and examines the competing arguments, shows how Ibsen's play has both contemporary relevance and moral depth, and demonstrates how Dr Stockmann's responses can be interpreted as an argument that complying with his duties to protect the public health do not force him to renege on his core commitments as a parent and as a citizen.

The telescopes at Hobart (Tasmania), Katherine (Northern Territory) and Yarragadee (Western Australia) are co-located with other space geodetic techniques including Global Navigation Satellite Systems (GNSS) and gravity infrastructure, and in the case of Yarragadee, satellite laser ranging (SLR) and Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) facilities. The correlation facility is based in Perth (Western Australia). This new facility will make significant contributions to improving the densification of the International Celestial Reference Frame in the Southern Hemisphere, and subsequently enhance the International Terrestrial Reference Frame through the ability to detect and mitigate systematic error. This, combined with the simultaneous densification of the GNSS network across Australia, will enable the improved measurement of intraplate deformation across the Australian tectonic plate. In this paper, we present a description of this new infrastructure and present some initial results, including telescope performance measurements and positions of the telescopes in the International Terrestrial Reference Frame. We show that this array is already capable of achieving centimetre precision over typical long-baselines and that network and reference source systematic effects must be further improved to reach the ambitious goals of VLBI2010.

Buckeye chiropractic: turbulence in a limited branch of medicine, 1915-1975.  

PubMed

In Ohio in 1915, the Platt-Ellis Law was enacted, a compromise between medical and chiropractic forces that defined chiropractic as a "limited branch of medicine or surgery." Practitioners of chiropractic, naprapathy, spondylotherapy, mechanotherapy, magnetic healing, and other "minor" healing arts excluding osteopathy and midwifery were all examined by the State Medical Board. The two disparate definitions created six decades of turmoil for chiropractic in Ohio. The 1920's were marked by the civil disobedience employed successfully in other states, with hundreds of unlicensed chiropractors choosing jail over fines. Multiple state organizations were formed, representing "straights, mixers, straight-mixers, mixing straights, minglers" and every other possible combination. The public accepted licensed and unlicensed practitioners, and doctors included their licensing status in their advertisements. PMID:11613404

Plant electrical memory.  

PubMed

Electrical signaling, short-term memory and rapid closure of the carnivorous plant Dionaea muscipula Ellis (Venus flytrap) have been attracting the attention of researchers since the XIX century. We found that the electrical stimulus between a midrib and a lobe closes the Venus flytrap upper leaf without mechanical stimulation of trigger hairs. The closing time of Venus flytrap by electrical stimulation is the same as mechanically induced closing. Transmission of a single electrical charge between a lobe and the midrib causes closure of the trap and induces an electrical signal propagating between both lobes and midrib. The Venus flytrap can accumulate small subthreshold charges, and when the threshold value is reached, the trap closes. Repeated application of smaller charges demonstrates the summation of stimuli. The cumulative character of electrical stimuli points to the existence of short-term electrical memory in the Venus flytrap. PMID:19704496

Electrochemical study of ellipticine interaction with single and double stranded oligonucleotides.  

PubMed

Ellipticine (5,11-dimethyl-6H-pyrido[4,3-b]carbazole) is an alkaloid that has been isolated from plants of an Apocynaceae family. It is one of the simplest naturally occurring alkaloids with a planar structure. Over the past decades, ellipticine became a very promising antitumor agent. Interaction with DNA is one of the most studied ellipticine effects on cell division. This phenomenon is not clearly explained so far. In our experiments we studied interaction of ellipticine with single-stranded and double-stranded oligonucleotides by electrochemical methods on mercury electrode. Differential pulse voltammetry was applied for ellipticine (Elli) and CA peak detection. Square wave voltammetry was applied for G peak detection. The effect of the interaction time and ellipticine concentrations on interactions of ellipticine with single- and double-stranded oligonucleotides was tested too. PMID:23869776

'Genipin' - the natural water soluble cross-linking agent and its importance in the modified drug delivery systems: an overview.  

PubMed

One of the popular approaches in controlling drug delivery from the polymeric carriers is suitably achieved by the inclusion of crosslinking agents into the formulations at different concentrations. Nevertheless, addition of the chemical crosslinkers such as glutaraldehyde, formaldehyde etc, used in the drug delivery systems causes very serious cytotoxic reactions. These chemical crosslinking agents did not offer any significant advantageous effects when compared to the natural crosslinking agents for instance genipin, which is quite less toxic, biocompatible and offers very stable crosslinked products. Based on the earlier reports the safety of this particular natural crosslinker is very well established, since it has been widely used as a Chinese traditional medicine for long-time, isolated from fruits of the plant Gardenia jasminoides Ellis. This concise article largely portrayed the value of this unique natural crosslinker, utilized in controlling the drug delivery from the various formulations. PMID:24041312

Misunderstood responses in police interrogation rooms.  

PubMed

Today, disability workers are finding numerous ways to talk to law officials about the above characteristics. They can do it during investigations, in police academy training segments, during officer roll-call sessions, on court witness stands, and during joint police-community conferences. I remember how the original list of eight character traits (Ellis & Luckasson, 1985) grabbed my attention so vividly after reading them for the first time. This experience makes me hopeful that today, when others voice the list of 20, it will have the same effect, with the positive outcome of these persons we work with and care about experiencing greater safety, security, and justice in the communities in which they live.

The Three Jet Process in Virtual Photon-Photon Annihilation.  

NASA Astrophysics Data System (ADS)

Three jet production in quantum chromodynamics is studied through the processes gamma^ *gamma^* to q| qg and g^* g^* to q| qg with respect to the jet broadening parameter called the transverse momentum perpendicular to the transverse thrust axis, developed by Ellis and Webber. The helicity amplitude methods developed by Farrar and Neri are used to derive the amplitudes for the Feynman diagrams of these three jet processes in lowest order in the coupling for each combination of photon and gluon polarizations and fermion chiralities. The transverse momentum perpendicular to the transverse thrust axis is then numerically determined by running the encoded formula through the VEGAS Monte Carlo integration routine. Results indicate the jet broadening remains rather flat with increasing photon virtuality. In the appendices, calculations towards the one loop correction for gammagamma^* to q| qg are given.

Spin structure of the neutron ({sup 3}He) and the Bjoerken sum rule  

SciTech Connect

A first measurement of the longitudinal asymmetry of deepinelastic scattering of Polarized electrons from a Polarized {sup 3}He target at energies ranging from 19 to 26 GeV ha, been performed at the Stanford Linear Accelerator Center (SLAC). The spin-Structure function of the neutron g{sub 1}{sup n} has been extracted from the measured asymmetries. The Quark Parton Model (QPM) interpretation of the nucleon spin-structure function is examined in light of the new results. A test of the Ellis-Jaffe sum rule (E-J) on the neutron is performed at high momentum transfer and found to be satisfied. Furthermore, combining the proton results of European Muon Collaboration (EMC) and the neutron results of E-142 the Bjoerken sum rule test is carried at high Q{sup 2} where higher order Perturbative Quantum Chromodynamics (PQCD) corrections and higher-twist corrections are smaller. The sum rule saturated to within one standard deviation.

Genetic skeletal dysplasias are a heterogeneous group of genetic disorders associated with abnormalities in the skeletal system frequently presenting with disproportionate short stature. There are over 100 distinct skeletal dysplasias which have been classified primarily on the basis of the clinical or radiographic characteristics. We have identified many genetic skeletal dysplasia disorders at Department of Pediatrics, Siriraj Hospital, Bangkok, Thailand. We have cases of achondroplasia, hypochondroplasia, pseudoachondroplasia, atelosteogenesis, pyknodysostosis, spondyloepiphyseal dysplasia (SED) congenita, spondylometaepiphyseal dysplasia (SMED), osteogenesis imperfecta type I, II and III, Ellis-van Creveld syndrome, cleidocranial dysostosis, thanatophoric dysplasia, rhizomelic chondrodysplasia punctata, trichorhinophalangeal syndrome, mucopolysaccharidosis I, II, IV and VI, mucolipidosis II, osteopetrosis, camptomelic dysplasia, metaphyseal dysplasia with spine involvement (Kozlowski type), Langer-Gideon syndrome and hypophosphatemic rickets. We have established a Genetic Skeletal Dysplasia Clinic at Siriraj Hospital since 1992, and see referrals from around the country. Genetic counseling is provided, including prenatal diagnosis and a multidisciplinary approach. PMID:8629144

Studies on transport phenomena in polymer solutions and suspensions flowing through tubes of tortuous wall geometry  

NASA Astrophysics Data System (ADS)

Attempts have been made to analyse the momentum and heat transfer characteristics in tortuous flow of non-Newtonian fluids such as suspensions and polymer solutions through tubes of diverging-converging geometry. The results of the study indicate that the transfer coefficients are significantly higher in such systems as compared to the conventional couette flow (through uniform cylindrical tubes). Moreover, the simultaneous increase in pressure drop due to the tortuous wall geometry has been observed to be relatively insignificant. Fluids with different rheological characteristics such as Bingham plastic fluids, pseudoplastic fluids, Ellis model fluids and fluids obeying Reiner-Philippoff rheology have been studied. The specific advantages of these geometries in providing enhanced performance efficiency have been effectively highlighted.

Jefferson's Blood  

NSDL National Science Digital Library

This companion Website to the recent broadcast of the Frontline documentary "Jefferson's Blood" is unusually rich in content, perhaps because it was used post-airing to feature Frontline's presence on the Web. Exploring the history and current controversy over Jefferson's longtime relationship with his slave and mistress Sally Hemings, the site features video excerpts from the broadcast; extended documentation of the DNA debate over Jefferson's extant ancestry; memoirs of four of Jefferson's slaves; essays and interviews from well-known Jefferson scholars, such as Joseph Ellis and Annette Gordon-Reed; discussions by sociologists, historians, and journalists of the nation's historical response to mixed ancestry and its threat to the white mystique; annotated links to premium Jefferson Websites; a teacher's guide; and a good deal more. The site admirably confirms that, when it comes to the question of race in America, there are few historical narratives more telling or more complicated than the one Thomas Jefferson wrote in his own blood.

The mating sociometer: a regulatory mechanism for mating aspirations.  

PubMed

Two studies (Ns = 80 and 108) tested hypotheses derived from Kirkpatrick and Ellis's (2001) extension and application of sociometer theory to mating aspirations. Experiences of social rejection-acceptance by attractive opposite-sex confederates were experimentally manipulated, and the impact of these manipulations on self-esteem, mating aspirations, and friendship aspirations was assessed. Results indicated that social rejection-acceptance by members of the opposite sex altered mating aspirations; that the causal link between social rejection-acceptance and mating aspirations was mediated by changes in state self-esteem; and that the impact of social rejection-acceptance by members of opposite sex was specific to mating aspirations and did not generalize to levels of aspiration in approaching potential same-sex friendships. This research supports a conceptualization of a domain-specific mating sociometer, which functions to calibrate mating aspirations in response to experiences of romantic rejection and acceptance.

Conflicts of Quarantine The Case of Jewish Immigrants to the Jewish State  

PubMed Central

Shaar Haaliya—Israel's Ellis Island during the mass immigration of the 1950s—is a case study that challenges the historian's understanding of the concept of quarantine. It was isolated and fenced off for declared health purposes and was widely referred to as a quarantine, but archival and historiographical documentation suggest that Israeli public health policy did not define it as such. I track the discussion and conflict surrounding Shaar Haaliya's function and perception as a quarantine. This is a story that illuminates the way fear of disease converged with fear of immigration as well as the way defiance of public health institutions took shape in a unique framework of citizenship and during a unique wave of migration.

Relaxation equations for two-dimensional turbulent flows with a prior vorticity distribution  

NASA Astrophysics Data System (ADS)

Using a Maximum Entropy Production Principle (MEPP), we derive a new type of relaxation equations for two-dimensional turbulent flows in the case where a prior vorticity distribution is prescribed instead of the Casimir constraints [R. Ellis, K. Haven, B. Turkington, Nonlinearity 15, 239 (2002)]. The particular case of a Gaussian prior is specifically treated in connection to minimum enstrophy states and Fofonoff flows. These relaxation equations are compared with other relaxation equations proposed by Robert and Sommeria [Phys. Rev. Lett. 69, 2776 (1992)] and Chavanis [Physica D 237, 1998 (2008)]. They can serve as numerical algorithms to compute maximum entropy states and minimum enstrophy states with appropriate constraints. We perform numerical simulations of these relaxation equations in order to illustrate geometry induced phase transitions in geophysical flows.

Influence of Crocetin on experimental atherosclerosis in hyperlipidamic-diet quails.  

PubMed

Antioxidants have been expected to have potential as antiatherogenic agents. Crocetin is a natural carotenoid antioxidant isolated from Gardenia jasminoids Ellis. Therefore, in the present study, we investigated the inhibitory effect of Crocetin on experimental atherosclerosis in quails. The atherosclerosis model was established by feeding hyperlipidamic diet to quail and Crocetin (25, 50, 100 mg/kg/day) was administered by oral gavage. At the 9th week, serum lipids, malondialdehyde and nitric oxide were measured, and Hematoxylin-Eosin (H&E) stains was used to investigate the histopathological changes of aorta. Results showed that Crocetin could reduce the levels of serum total cholesterol, triglyceride, low density lipoprotein cholesterol and inhibit the formation of aortic plaque. Crocetin could also reduce malondialdehyde and inhibit the descending of nitric oxide in serum. The results suggested that Crocetin could inhibit the formation of atherosclerosis in quails, which might be related to the hypolipidemic effects along with the antioxidative properties of Crocetin.

Antihyperlipidemic effect of crocin isolated from the fructus of Gardenia jasminoides and its metabolite Crocetin.  

PubMed

The pancreatic lipase inhibitors were isolated from the fructus of Gardenia jasminoides ELLIS, and their antihyperlipidemic activities were measured. Gardeniae fructus (GF) water extract inhibited pancreatic lipase activity. Crocetin and crocin were isolated from GF water extract as inhibitors of pancreatic lipase with an IC50 value of 2.1 and 2.6 mg/ml (triolein as a substrate). Crocin and crocetin significantly inhibited the increase of serum TG level in corn oil feeding-induced triglyceridemic mice, as well as that of serum triglyceride and total and LDL cholesterol levels in Triton WR-1339-induced hyperlipidemic mice. These compounds also showed hypolipidemic activity in hyperlipidemic mice induced by high cholesterol, high fat or high carbohydrate diets for 5 weeks. The results suggest that the hypolipidemic activity of GF and its component crocin may be due to the inhibition of pancreatic lipase and crocin, and its metabolite, crocetin, can improve hyperlipidemia.

The species cordiforme Meek and Hayden, distans Whitfield, canadense Whiteaves, and dubium Hyatt (probably including whitneyi J. P. Smith), variously assigned to the genera Amaltheus, Quenstediceras, Amoeboceras, and Cardioceras, and subtumidum Whitfield and Hovey, assigned to Aegoceras, include all the previously described species of Jurassic ammonites that are considered in this paper. Material accumulated in the National Museum at Washington, mainly through the efforts of field parties of the United States Geological Survey, has shown, however, the presence of a number of undescribed forms of considerable scientific interest. These new species were obtained mainly from the Sundance formation of Wyoming. One comes from the Ellis formation of Montana, one from Jurassic beds near Lillooet, British Columbia, and three from the Cardioceras-bearing beds near the base of the Naknek formation of Alaska.

In cardiac medicine, Dr. Michael Ellis DeBakey is the undisputed pioneer of this century, maybe even in history. The design of the ventricular assist device (VAD), the Dacron-created artificial blood vessel and his many other firsts revolutionized heart surgery (specifically aortic surgery) forever. In fact, his contributions were enormous and left and amazing legacy. DeBakey was known to have a temper and that he was a very difficult surgeon to work with. However, even his critics could not deny the impact he had on the world of medicine. In his early nineties, he still practiced surgery. DeBakey was a man that accomplished all he set out to do and died on early July 2008. PMID:19842897

Some performance characteristics of a Prussian blue battery  

SciTech Connect

Neff (1978), Ellis et al. (1981), and Itaya et al,. (1982) have studied the thermodynamic and kinetic characteristics of the electrochemical oxidation and reduction of thin films of Prussian blue (PB) on various substrates. The present note has the objective to point out the feasibility of a Prussian blue battery, taking into account also the determination of some preliminary performance characteristics of a Prussian blue battery. It is shown that two half-cells could be combined to make a PB battery which, in the uncharged state, would consist of PB as both anode and cathode. One of the major problems encountered is the adherence of the PB deposit on the carbon substrate. 9 references.

We present a new, non-variational orbital-optimization scheme for the antisymmetric product of one-reference orbital geminal wave function. Our approach is motivated by the observation that an orbital-optimized seniority-zero configuration interaction (CI) expansion yields similar results to an orbital-optimized seniority-zero-plus-two CI expansion [L. Bytautas, T. M. Henderson, C. A. Jimenez-Hoyos, J. K. Ellis, and G. E. Scuseria, J. Chem. Phys. 135, 044119 (2011)]. A numerical analysis is performed for the C2 and LiF molecules, for the CH2 singlet diradical as well as for the symmetric stretching of hypothetical (linear) hydrogen chains. For these test cases, the proposed orbital-optimization protocol yields similar results to its variational orbital optimization counterpart, but prevents symmetry-breaking of molecular orbitals in most cases.

Regional and temporal changes in epizoobiontic bryozoan-communities of Flustra foliacea (Linnaeus, 1758) and implications for North Sea ecology  

NASA Astrophysics Data System (ADS)

Until recently, bryozoans have not been used as indicators for changes in bottom communities or climate control in the North Sea Basin, despite a 200-year history of bryozoan collecting. The epizoobiontic bryozoan fauna of Flustra foliacea (Linnaeus, 1758) was analysed on 51 sample stations kept in four German museums. The samples cover the entire North Sea and different time periods (1776-2008, mainly the period of 1904/1905 compared to 1980-87). Cluster analysis shows a differentiation into a northern and a southern North Sea assemblage. The northern assemblage is characterized by Amphiblestrum flemingii (Busk, 1854), Callopora dumerilii (Audouin, 1826) and Tricellaria ternata (Ellis & Solander, 1786), while the southern North Sea is characterized by Electra pilosa (Linnaeus, 1767), Crisia eburnea (Linnaeus, 1758) and Plagioecia patina (Lamarck, 1816). Spatial separation approximately follows the 50 m depth contour. The temporal distribution patterns of bryozoans are discussed in terms of NAO (North Atlantic Oscillation) and temperature variations.

On the incremental validity of irrational beliefs to predict subjective well-being while controlling for personality factors.  

PubMed

This research examines the incremental validity of irrational thinking as conceptualized by Albert Ellis to predict diverse aspects of subjective well-being while controlling for the influence of personality factors. Rational-emotive behavior therapy (REBT) argues that irrational beliefs result in maladaptive emotions leading to reduced well-being. Although there is some early scientific evidence for this relation, it has never been investigated whether this connection would still persist when statistically controlling for the Big Five personality factors, which were consistently found to be important determinants of well-being. Regression analyses revealed significant incremental validity of irrationality over personality factors when predicting life satisfaction, but not when predicting subjective happiness. Results are discussed with respect to conceptual differences between these two aspects of subjective well-being. PMID:21044476

The High Plains is a major agricultural area, supported primarily by water from the High Plains aquifer, which is used to irrigate wheat and corn and to raise cattle and swine. The U.S. Geological Survey (USGS) and the Oklahoma Water Resources Board (OWRB) began a study of the High Plains aquifer in 1996. One purpose of the study was to develop a ground-water flow model that the OWRB could use to allocate the amount of water withdrawn from the a aquifer. The study area in Oklahoma covers all or parts of Beaver, Cimarron, Dewey, Ellis, Harper, Texas, and Woodward Counties. To provide appropriate hydrologic boundaries for the ground-water flow model, the study area was expanded to include parts of Colorado, Kansas, New Mexico, and Texas.

Experimental verification of the dielectric constant of a magnetized rotating plasma  

NASA Astrophysics Data System (ADS)

Direct measurements confirm that the magnetized plasma perpendicular dielectric constant has a linear dependence on the plasma density for fixed magnetic field, as predicted by magnetohydrodynamic (MHD) theory. In experiments performed on the Maryland Centrifugal Experiment (MCX) [R. F. Ellis, A. B. Hassam, S. Messer, and B. R. Osborn, Phys. Plasmas, 8, 2057 (2001)], line-averaged hydrogen plasma electron density is measured using a Mach-Zehnder interferometer. For small rotational Alfven Mach numbers, the measured size of the perpendicular plasma dielectric constant is also in agreement with MHD theory. Plasma density in the range of (1-8)×1020 m-3 and relative perpendicular plasma dielectric constant of the order of 106 are measured.

A qualitative and quantitative survey was made of the aerospora above an Eragrostis curvula (Schrad.) Nees pasture. The pasture, which lay adjacent to a field of Panicum coloratum L. where an outbread of ovine photosensitivity had occurred, was not grazed during the survey. A Burkard volumetric spore trap was used to sample the aerospora continuously for 10 months. Twenty components of the aerospora were recognized: spores of 9 genera of fungi (Cladosporium, Alternaria, Epicoccum, Drechslera, Pithomyces chartarum (Berk. & Curt.) M. B. Ellis, Nigrospora, Sporormia, Curvularia, Spegazzinia); 8 recognizable but unidentified spore types; hyphal fragments and pollen grains. Cladosporium conidia comprised 83,37% of the total aerospora. Conidia of Pithomyces chartarum formed a small (0,29%) but significant component of the aerospora, since this fungus is known to cause hepatogenous photosensitivity. PMID:460819

The application of Weierstrass elliptic functions to Schwarzschild null geodesics  

NASA Astrophysics Data System (ADS)

In this paper, we focus on analytical calculations involving null geodesics in some spherically symmetric spacetimes. We use Weierstrass elliptic functions to fully describe null geodesics in Schwarzschild spacetime and to derive analytical formulae connecting the values of radial distance at different points along the geodesic. We then study the properties of light triangles in Schwarzschild spacetime and give the expansion of the deflection angle to the second order in both M/r0 and M/b where M is the mass of the black hole, r0 the distance of the closest approach of the light ray and b the impact parameter. We also use the Weierstrass function formalism to analyze other more exotic cases such as Reissner-Nordstrøm null geodesics and Schwarzschild null geodesics in four and six spatial dimensions. Finally we apply Weierstrass functions to describe the null geodesics in the Ellis wormhole spacetime and give an analytic expansion of the deflection angle in M/b.

A Collection of 4th of July Speeches  

NSDL National Science Digital Library

The 4th of July brings out orators of all stripes, and over the past two centuries many distinguished Americans have seen fit to offer their own encomia on this day. This lovely collection from the University of Missouri's Ellis Library brings together published pamphlets made on Independence Day from 1791 to 1925. The speeches take a look at crucial topics from this time period, including civic duty, religion, national politics, and the Civil War. The majority of these pamphlets were published in New England, and the collection also includes pamphlets from Louisiana, North Carolina, Illinois, and Indiana. First-time visitors may wish to start by reading Charles F. Adams' oration "before the city authorities of Boston on the fourth of July, 1872" and then move on to Oliver Wendell Holmes' talk before that same body in 1863. Visitors are encouraged to browse through the pamphlets, and they can also use the search engine as well.

Disbursement of $65 million to the State of Texas for construction of a Regional Medical Technology Center at the former Superconducting Super Collider Site, Waxahachie, Texas  

SciTech Connect

As part of a settlement agreement between the US DOE and the State of Texas, DOE proposes to transfer $65 million of federal funds to the Texas National Research Laboratory Commission (TNLRC) for construction of the Regional Medical Technology Center (RMTC) to be located in Ellis County, Texas. The RMTC would be a state-of-the-art medical facility for proton cancer therapy, operated by the State of Texas in conjunction with the University of Texas Southwestern Medical Center. The RMTC would use the linear accelerator assets of the recently terminated DOE Superconducting Super Collider Project to accelerate protons to high energies for the treatment of cancer patients. The current design provides for treatment areas, examination rooms, support laboratories, diagnostic imaging equipment, and office space as well as the accelerators (linac and synchrotron) and beam steering and shaping components. The potential environmental consequences of the proposed action are expected to be minor.

A genipin-gelatin gel dosimeter for radiation processing  

NASA Astrophysics Data System (ADS)

Genipin, a fruit extract from Gardenia jasminoides Ellis, forms cross-links in solutions of gelatin, to form a blue hydrogel that bleaches quantitatively upon irradiation and the colour change can be measured with a spectrophotometer. With the addition of sulphuric acid this dosimeter is sufficiently sensitive for quality assurance of radiotherapy level dosimetry. Without sulphuric acid the gel has a reduced sensitivity and responds linearly with dose between 100 and 1000 Gy, making it potentially useful as a dosimeter for radiation processing applications such as the phytosanitary irradiation treatment of food. We investigated the dose response characteristics of this new formulation and found that the darker gels are more sensitive to dose and have a reduced uncertainty.

Physical and geometrical interpretation of the {epsilon}{<=}0 Szekeres models  

SciTech Connect

We study the properties and behavior of the quasipseudospherical and quasiplanar Szekeres models, obtain the regularity conditions, and analyze their consequences. The quantities associated with radius and mass in the quasispherical case must be understood in a different way for these cases. The models with pseudospherical foliation can have spatial maxima and minima, but no origins. The mass and radius functions may be one increasing and one decreasing without causing shell crossings. This case most naturally describes a snakelike, variable density void in a more gently varying inhomogeneous background, although regions that develop an overdensity are also possible. The Szekeres models with plane foliation can have neither spatial extrema nor origins, cannot be spatially flat, and they cannot have more inhomogeneity than the corresponding Ellis model, but a planar surface can be the boundary between regions of spherical and pseudospherical foliation.

Immigrants on an Atlantic liner (1900s), still imageSite: DNA Interactive (www.dnai.org)  

NSDL National Science Digital Library

DNAi location: Chronicle>Threat of the Unfit>threats Eugenicists were concerned about the hundreds of thousands of southern and eastern Europeans who were entering the country each year through the U.S. immigration facility at Ellis Island, New York. Eugenics Record Office Superintendent Harry Laughlin provided a scientific rationale for growing anti-immigration sentiments in American society. In three Congressional testimonies, he presented data that purported to show that southern and eastern European countries were "exporting" genetic defectives to the United States who had disproportionately high rates of mental illness, crime, and social dependency. The resulting Immigration Restriction Act of 1924 reduced southern and eastern European immigrants to less than 15,000 per year.

Two new species of the gorgonian inhabiting barnacle, Conopea (Crustacea, Cirripedia, Thoracica), from the Gulf of Guinea  

PubMed Central

Abstract Two new species of Conopea (Say 1822) are described from the Gulf of Guinea: Conopea saotomensis sp. n.and Conopea fidelis sp. n. These two new species were collected from the historically isolated volcanic islands of São Tomé and Príncipe. The relationship between Conopea saotomensis sp. n., Conopea fidelis sp. n.and two other Atlantic barnacle species, Conopea calceola (Ellis 1758) and Conopea galeata (Linnaeus 1771), is examined. The methods employed are the construction of a molecular phylogeny using mitochondrial COI and nuclear H3 gene sequence data along with morphological comparisons of calcareous and cuticular body parts. It is found that Conopea saotomensis sp. n., Conopea fidelis sp. n.and Conopea calceola are most closely related to each other but the relationship among them is unresolved. Gorgonian hosts are identified. Preliminary observations show species level host specificity for Conopea fidelis sp. n.

Joseph Hersey Pratt (1872-1956): An early proponent of cognitive-behavioural therapy in America.  

PubMed

The treatment of mild psychoneuroses in America began shifting in the 1950s from Freudian psychoanalysis to various forms of psychotherapy that do not delve into patient's subconscious. Some of the new approaches were termed cognitive, behavioural or cognitive behavioural therapy and in America were practised notably by Joseph Wolpe, Albert Ellis and Aaron T Beck. Modern psychiatric literature makes little mention of two prior innovators in this area - the French neurologist Jules Dejerine and his Boston disciple Joseph H Pratt. In the early 1900s, Dejerine treated patients at La Salpêtrière in Paris using techniques adopted subsequently by Pratt during the 1930s and employed by the trio some decades later. This paper revisits the early history of psychotherapy in America and includes a brief summary of Pratt's medical career. PMID:24585845

The effect of the variation of atmospheric oxygen levels throughout the Phanerozoic on the size of foraminifera tests  

NASA Astrophysics Data System (ADS)

In our experiment, we wanted to try to identify a correlation between the size of both fossilized and living foraminifera and the environmental patterns at various time periods. Based on previous scientific findings, we had a basic theoretical hypothesis that increases in the atmospheric oxygen at various ages of time had a proportional affect on the average size of these foraminifera. In order to gather data, we collected and recorded the size and time period of over 36,000 foraminifera using the encyclopedia series: “Catalogue of Foraminifera”, compiled by Ellis and Messina. Ultimately, we discovered that there was indeed a strong correlation between the maximum size of the foraminifera and the oxygen level at the time age it was discovered. This data also helped us explain the possible causes of 3 mass extinctions (particularly the Permian-Triassic Boundary Extinction), which occurred at the same time when atmospheric oxygen decreased dramatically.

Quantum cosmology of the superstring universe  

NASA Astrophysics Data System (ADS)

We study the quantum cosmology of the string universe obtained by embedding the Robertson-Walker metric in the non-linear model of Antoniadis, Bachas, Ellis and Nanopoulos (ABEN). We find that the quantum model has some unusual features not seen in the classical model. Initially, the universe exists in a series of metastable bound states with scale factor taking discrete values. Then the universe tunnels through a barrier and comes out in an inflationary state. This tunneling (or evolution in imaginary time) also has the effect of heating up the matter field so that we have the conditions of chaotic inflation. Our asymptotic solutions agree with those obtained from the classical Einstein equations by ABEN.

HUBBLE AND KECK DISCOVER GALAXY BUILDING BLOCK  

NASA Technical Reports Server (NTRS)

This NASA Hubble Space Telescope image shows a very small, faint galaxy 'building block' newly discovered by a unique collaboration between ground- and space-based telescopes. Hubble and the 10-meter Keck Telescopes in Hawaii joined forces, using a galaxy cluster which acts as gravitational lens to detect what scientists believe is one of the smallest very distant objects ever found. The galaxy cluster Abell 2218 was used by a team of European and American astronomers led by Richard Ellis (Caltech) in their systematic search for intrinsically faint distant star-forming systems. Without help from Abell 2218's exceptional magnifying power to make objects appear about 30 times brighter, the galaxy building block would have been undetectable. In the image to the right, the object is seen distorted into two nearly identical, very red 'images' by the gravitational lens. The image pair represents the magnified result of a single background object gravitationally lensed by Abell 2218 and viewed at a distance of 13.4 billion light-years. The intriguing object contains only one million stars, far fewer than a mature galaxy, and scientists believe it is very young. Such young star-forming systems of low mass at early cosmic times are likely to be the objects from which present-day galaxies have formed. In the image to the left, the full overview of the galaxy cluster Abell 2218 is seen. This image was taken by Hubble in 1999 at the completion of Hubble Servicing Mission 3A.

RIKEN SCHOOL ON QCD TOPICS ON THE PROTON.  

SciTech Connect

The RIKEN School on QCD titled ''Topics on the Proton'' was held on March 26th, 2003 at the Nishina Memorial Hall of RIKEN, Wako, Saitama, Japan, sponsored by REEN (the Institute of Physical and Chemical Research). The school was the third of a new series with a broad perspective of hadron and nuclear physics. The organization and the size of the school were a little different from those of the previous ones. Prof. John Ellis, known as the world best theorist in particle and nuclear physics, has been appointed in RIKEN as an Eminent Scientist, which enables us to plan a collaboration with him for coming three years. As the first year activity, we asked him to give a keynote talk in the JPS spring meeting focusing on the structure of proton, and also to give lectures in RIKEN for younger Japanese scientists on the subjects related the structure of the proton. He kindly agreed on both and we then decided to have a one-day school by supplementing his course with a course on experimental aspects of the proton structure. One of us (N.S.) agreed to give the latter. This time, Theoretical Physics Laboratory joined Radiation Laboratory to organize the school. The purpose of the school was to offer young researchers an opportunity to learn theoretical aspects of the proton structure with a broad perspective including supersymmetry and the related experimental aspects. We had a theoretical course consisting of 3 one-hour lectures by Prof. Ellis and a experimental course consisting of 2 one-hour lectures by Prof. Saito.

Stratigraphic characterization of the Anthropocene: a progress report  

NASA Astrophysics Data System (ADS)

Rapid and large-scale anthropogenic changes have led to the concept that we are now living through the beginning of the Anthropocene Epoch - an interval of geological time dominated by human influence. The term was proposed little more than a decade ago by Paul Crutzen, the Nobel Prize-winning atmospheric chemist, and has since been widely used - and sharply debated. Its stratigraphic analysis needs considering the various kinds of historical and environmental change in terms of geological - or more precisely stratigraphic - change. Lithostratigraphic change, for instance, is strikingly represented by the spread of the 'urban stratum', the refashioning of sand, clay and limestone into our buildings, foundations and transport systems. Biostratigraphic changes include the ongoing mass extinction event and the effect of invasive species (while deep human-made bioturbation is a novel aspect the fossil record). Chemostratigraphic changes include the reshaping of the Earth's natural carbon, phosphorus and nitrogen cycles. As regards the potential formalizing of the Anthropocene, one question to be pursued relates to the chronostratigraphic definition of the phenomena involved: that is, given that many of these transformations are diachronous on human timescales, can an Anthropocene Series, with a synchronous time boundary, be characterized and mapped across the Earth's surface? Efforts to answer this question (Williams et al. 2011; Waters et al., in press) should help in the understanding of the Anthropocene within its geological context, and also in exploring the stratigraphic relation between time and rock generally at very fine stratigraphic timescales.

Late-Holocene succession of dinoflagellates in an Antarctic fjord using a multi-proxy approach: paleoenvironmental genomics, lipid biomarkers and palynomorphs.  

PubMed

Recent work has shown that paleoenvironmental genomics, i.e. the application of genomic tools to analyze preserved DNA in sedimentary records, is a promising approach to reconstruct the diversity of past planktonic communities. This provides information about past ecological and environmental changes. A major advantage of this approach is that individual species, including those that did not leave other characteristic markers, can be identified. In this study, we determined which dinoflagellate marker (i.e. 18S rDNA, dinosterol or dinocysts) provided the most detailed information about the late-Holocene succession of dinoflagellates in an Antarctic Fjord (Ellis Fjord, Vestfold Hills). The preserved rDNA revealed two intervals in the 2750-year-old sediment record. The dinoflagellate diversity was the highest until approximately 1850 cal yr bp and included phylotypes related to known dinosterol producers. A lower concentration of dinosterol in sediments <1850 cal yr bp coincided with a community shift towards a predominance of the autotrophic sea-ice dinoflagellate Polarella glacialis, which is not a source of dinosterol. Remarkably, cultures of P. glacialis are known to produce other diagnostic sterols, but these were not recovered here. In addition, conspicuous resting cysts of P. glacialis were not preserved in the analyzed sediments. Overall, dinocysts were rare and the paleoenvironmental genomics approach revealed the highest diversity of dinoflagellates in Ellis Fjord, and was the only approach that recorded a shift in dinoflagellate composition at approximately 1850 cal yr bp indicative of a colder climate with more extensive ice cover - this timing coincides with a period of changing climate reported for this region.

Pore-Scale Modeling of Non-Newtonian Flow in Porous Media  

NASA Astrophysics Data System (ADS)

The thesis investigates the flow of non-Newtonian fluids in porous media using pore-scale network modeling. Non-Newtonian fluids show very complex time and strain dependent behavior and may have initial yield stress. Their common feature is that they do not obey the simple Newtonian relation of proportionality between stress and rate of deformation. They are generally classified into three main categories: time-independent, time-dependent and viscoelastic. Two three-dimensional networks representing a sand pack and Berea sandstone were used. An iterative numerical technique is used to solve the pressure field and obtain the flow rate and apparent viscosity. The time-independent category is investigated using two fluid models: Ellis and Herschel-Bulkley. The analysis confirmed the reliability of the non-Newtonian network model used in this study. Good results are obtained, especially for the Ellis model, when comparing the network model results to experimental data sets found in the literature. The yield-stress phenomenon is also investigated and several numerical algorithms were developed and implemented to predict threshold yield pressure of the network. An extensive literature survey and investigation were carried out to understand the phenomenon of viscoelasticity with special attention to the flow in porous media. The extensional flow and viscosity and converging-diverging geometry were thoroughly examined as the basis of the peculiar viscoelastic behavior in porous media. The modified Bautista-Manero model was identified as a promising candidate for modeling the flow of viscoelastic materials which also show thixotropic attributes. An algorithm that employs this model was implemented in the non-Newtonian code and the initial results were analyzed. The time-dependent category was examined and several problems in modeling and simulating the flow of these fluids were identified.

Symposium: Writing the Test Question IsnÃÂt Enough! Presented at Experimental Biology, New Orleans LA Monday, April 20, 2009, 8:00-10:00 AM Chairs: Vikki McCleary and Kathy sukalski, Univ. of North Dakota Well constructed multiple choice items can provide a valid, reliable, and unbiased means to assess student learning. Machine scoring and analysis allows for a rapid turnaround of results and provides information about the patterns of responses to individual items. This symposium focused on the construction of valid, reliable multiple choice questions with an emphasis on those that evaluate the studentsÃÂ critical thinking ability in the context of specific learning objectives. The session was introduced by Ellis Bell who considered the process of evaluating student achievement in both content knowledge and critical thinking. Decisions must be made about the types of questions to use (essay, short answer, multiple choice) and timing of the examinations, (midterm and final, block exams). Vikki McCleary focused on multiple choice examinations and reviewed the optimization of stems, answers, and distracters and the evaluation of items according to BloomÃÂs taxonomy. Charles Hosford outlined the use of standard item analyses to improve test questions. The assessment of student understanding during class lectures using multiple choice questions was addressed by Jeannine Matz.

Sharing successful strategies for accomplishing this goal is one of the driving forces for the International Society for Biological and Environmental Repositories (ISBER). For more information about ISBER see www.isber.org . ISBER's Best Practices for Repositories (Best Practices) reflect the collective experience of its members and has received broad input from other repository professionals. Throughout this document effective practices are presented for the management of specimen collections and repositories. The term "Best Practice" is used in cases where a level of operation is indicated that is above the basic recommended practice or more specifically designates the most effective practice. It is understood that repositories in certain locations or with particular financial constraints may not be able to adhere to each of the items designated as "Best Practices". Repositories fitting into either of these categories will need to decide how they might best adhere to these recommendations within their particular circumstances. While adherence to ISBER Best Practices is strictly on a voluntary basis, it is important to note that some aspects of specimen management are governed by national/federal, regional and local regulations. The reader should refer directly to regulations for their national/federal, regional and local requirements, as appropriate. ISBER has strived to include terminology appropriate to the various specimen types covered under these practices, but here too, the reader should take steps to ensure the appropriateness of the recommendations to their particular repository type prior to the implementation of any new approaches. Important terms within the document are italicized when first used in a section and defined in the glossary. The ISBER Best Practices are periodically reviewed and revised to reflect advances in research and technology. The third edition of the Best Practices builds on the foundation established in the first and second editions which were published in 2005 and 2008, respectively. PMID:24844904

Biological evaluation of endophytic fungus, Chaetomium globosum JN711454, as potential candidate for improving drug discovery.  

PubMed

The main objective of this research work focused on investigating the biological and chemical aspects of endophytic fungus Chaetomium globosum, for pharmaceutical purposes to improve the drug discovery process. The endophytic C. globosum was isolated from healthy leaves of Egyptian medicinal plant Adiantum capillus-veneris collected from Saint Katherine Protectorate, Sinai, Egypt. The identification of C. globosum was on the basis of classical and molecular taxonomy. Gene encoding for 18S rRNA was partially sequenced, submitted to the GenBank and got the accession number JN711454, to resolve the phylogenetic relations with fungal ancestor using phylogenetic tree. To explore the biosynthetic power of endophytic C. globosum JN711454, the fungus was cultivated over five different media, oatmeal, rice, yeast malt glucose, potato dextrose agar (PDA) and Czapek's dox media, for 3 weeks at 30 °C, followed by extraction with different solvents, ethyl acetate (EA), and methanol. The ethyl acetate extract of C. globosum cultivated on PDA medium was the most potent extract. It showed strong antioxidant activity with EC50 11.5 ?g/ml, potent anticancer activity with 55 % toxicity toward HepG-2 cells at 100 ?g/ml and 66 % cytotoxicity to FGC4 cells at 250 ?g/ml, promising butyrylcholinesterase inhibitory activities (>85 %), and moderate antimicrobial and stopped the attachment of HSV-2 virus to VERO cells. The metabolomic profiling of PDA-EA extract using LC-MS revealed the presence of several metabolites to which the observed bioactivities could be attributed. Here we report for the first time inhibitory activity of endophytic C. globosum JN711454 secondary metabolites to butyrylcholinesterase, one of neuro hydrolase enzymes that play a major role in development of Alzheimer's disease.

Evolution of Permeability and Pore Structure of Porous Limestone at Elevated Temperature  

NASA Astrophysics Data System (ADS)

Evolution of Permeability and Pore Structure of Porous Limestone at Elevated Temperature Harrison Lisabeth, Katherine Watter and Wenlu Zhu Dept. of Geology, University of Maryland, College Park 20742 Permeability of porous rocks depends strongly on porosity and pore geometry. Natural situations are often complex, with concurrent inelastic deformation mechanisms and simultaneous metamorphic or diagenetic reactions. Coexistence of many mechanical (e.g., consolidation due to elevated overburden pressure, or shear induced crack opening) and chemical (e.g., dissolution and precipitation) processes can significantly modify pore space and thus change permeability. Developing robust constitutive laws for the dominant processes affecting permeability requires better understanding of the interactions between each mechanism. With increasing pressure and temperature, rocks undergo a transition in failure mode from localized brittle failure to non-localized plastic flow. The influence of temperature on brittle-ductile transition remains poorly understood in carbonate rocks. In this study, we deformed porous Indiana limestone samples with initial porosity of ~17% at temperatures of 298, 323, 373 and 423 K under confining pressures ranging from 10 to 120 MPa. Concomitant changes in permeability and sonic velocity were measured during deformation. Compared to nominal dry experiments conducted at room temperature, we found that the presence of water enhances compaction and considerably lower the rock strength. With increasing pressure and temperature, failure modes change from localized to distributed in the deformed samples, and the water weakening effect becomes more pronounced. Preliminary microstructural analyses indicate that mechanical twinning, microcracking and pore collapse coexist in the deformed samples. Based on these observations, we postulate that the water weakening at elevated temperature result from the interplay between crystal plasticity, microcracking and pore collapse.

The Diary of Frances Jacobs: Astronomical Observations by a 19th-century Oregon Woman  

NASA Astrophysics Data System (ADS)

This abstract summarizes my research, transcription and editing of Francis Jacob's 170-page handwritten astronomical diary. This diary is a unique example of a time in early Portland history, illustrating the mind of a young woman who was interested in science and astronomy. Reflected in her diary are the discoveries and mention of leading astronomers of the day like Emerson Bernard and Edward Pickering. Francis Jacobs lived in an era of the great refractors For example, ``The Leviathan," built by Lord Rosse in Ireland was completed in 1847. In this 72-inch telescope, stars of 18th magnitude could be seen. The first spiral nebulae to be revealed was M51 - known today as the Whirlpool Galaxy. The Earl was the first to suggest that these spirals could actually be rotating masses of stars. At the turn of the century, study of observational astronomy was rooted in naked eye observing, study of binary stars and nebula. This was a time when women were becoming interested in the sciences and had begun to play an important role in science and astronomy. It was an incredible inspiration for other women across the country to hear what was happening on the astronomical frontiers at Harvard. Some constellation asterisms used in Francis Jacob's diary were different than they are today. One asterism in particular, the Egyptian Cross, is relatively unknown now. The summer triangle and winter circle asterisms were used in her notes and obviously popular in her era, as today. Her written comments included some Messier catalogue numbers and in some case written on her sketches and diagrams nicknames, such as the 'Dumbbell' nebula. She also referred to M99 as `St. Katherine's Wheel', a nickname that is not in common use today.

JOVE/NASA Funded Search for Aqueously Altered Minor Planets Provides Undergraduates with Valuable Research Experience  

NASA Astrophysics Data System (ADS)

A Joint Venture in Research Grant from NASA has enabled a team of undergraduates from Valdosta State University, lead by Dr. Martha Leake, to spectroscopically and photometrically search for aqueously altered minor planets. To carry out the necessary preparations, calculations, and measurements, students are using CCD and Spectroscopy equipment provided by VSU, a .4-m telescope in Valdosta, in addition to a .9-m telescope at Kitt Peak, belonging to the SARA consortium (Southeastern Association for Research in Astronomy). Focusing on primitive C-class asteroids, the team is looking for water of hydration, in the form of absorption bands occurring at specific, previously researched wavelengths. The evidence occurring at these wavelengths suggests the extent of alteration in small solar-system bodies. Equipment being utilized includes an ST-6 and Axiom CCD Cameras, and an Optomechanics 10C spectrograph, and several "intermediate-band" filters to target the specified wavelengths essential to detection o f aqueously altered minerals. Test runs on Valdosta's .4-m are currently being conducted to inspect new equipment and develop analogs for more efficient observation runs on SARA's .9-m telescope. Students were originally chosen on a competitive basis, having to submit formal applications. Three were selected for JOVE research: Roy Kilgard, senior astronomy major; Katherine Semmes, junior physics major; and myself, Lisa Watkins, sophomore astronomy major. Roy Kilgard graduated in the Spring of 1997 with his Astronomy degree, and the position was filled by Brent Collier, a junior Geosciences major at VSU. Students' research is monitored and directed by the project mentor and grant recipient, Dr. Martha Leake.

Lady Liberty's interior will be closed to visitors starting October 29th, 2011 and the plan is for the interior to reopen after a year. After the September 11 attacks, the Statue of Liberty monument was closed because rescuers could not get them out in an emergency. After almost $7 million in renovations to fire and security systems the base, pedestal, and observation deck were reopened. This time, the renovations will cost just over $27 million, and will include safety upgrades to the monument's stairs, elevators, and electrical and mechanical systems. Tourists will still be able to visit Liberty Island and views of the statue will remain "relatively unobstructed" during the renovation. According to Interior Secretary Ken Salazar, all of these new improvements to the Statue of Liberty will bring "a 19th century icon into the 21st century."

The one-by-one method for releasing cranes  

USGS Publications Warehouse

Although the trend for the past 2 decades has been toward releasing naive groups of juveniles after a lengthy acclimation period, in 5 separate releases (1996-2000) we tested the idea that naive juvenile greater sandhill cranes (Grus canadensis tabida) would survive better if released singly into a wild flock of predator-wary birds than if left as a group, inexperienced at foraging and ill prepared to avoiding predators. We released 3 groups of hand-reared juveniles (n = 12 [1996]; n = 8 [1998], n = 12 [1999]) into a wild flock of sandhill cranes (ca 300 birds) on wintering grounds near Gila Bend, Arizona. Another 8 parent-reared colts were released into a small group (4) of subadult greater sandhill cranes (survivors of the 1996 trucking experiment [Ellis, et al. 1997; Ellis et al. 2001, Mummert et al. 2001]) in northcentral Arizona. Another 8 juveniles, costume-reared from hatching, were released into wild sandhill crane flocks in central Wisconsin at autumn staging areas. In all of these tests, cranes were released 1 or 2 at a time, either at the periphery of a wild flock or at a known roost site. Most birds were released in daylight at a foraging area, but because this was a pilot project, we tried a variety of methods. We released a few individuals at odd times (e.g., midnight) and in odd ways (e.g., by flushing a release crane as a wild flock passed overhead). A few birds were initially left stranded after we placed them at ephemeral roosts that had been used recently, but not subsequent to our visit. However, once we made the necessary adjustments, and regardless of release time or situation, all of our cranes very quickly joined their adoptive flocks. We experienced excellent survival, including 100% survival for all 8 of our parent-reared fledgling colts released on the summering ground and followed until they disappeared at the time of migration. Further, all (32) hand-reared birds released on the wintering grounds survived the winter. Also all 8 of the juveniles reared and released in Wisconsin successfully migrated south and returned north to Central Wisconsin the following spring. These results recommend the one-by-one method as a promising strategy for releasing juvenile cranes with minimal training, handling, and maintenance. The method provides a likely strategy for building wild flocks of endangered cranes once a core group is established by some other method.

The Gerasimov Drell Hearn sum rule  

NASA Astrophysics Data System (ADS)

? Sum rules measurements involving the spin structure of the nucleon like those due to Bjorken, Ellis and Jaffe and the one due to Gerasimov, Drell and Hearn allow us to study the structure of strong interactions. At long distance scales in the confinement regime the Gerasimov-Drell-Hearn (GDH) sum rule (Eq. (1)) connects static properties of the nucleon-like the anomalous magnetic moment and the nucleon mass-with the difference of spin dependent doubly polarized total absorption cross sections of real photons. Hence, the full spin-dependent excitation spectrum of the nucleon is being related to its static properties. The sum rule has not been investigated experimentally until recently. Now, for the first time this fundamental sum rule is verified by the GDH-Collaboration with circularly polarized real photons and longitudinally polarized nucleons at the two accelerators ELSA and MAMI. The investigation of the response of the proton as well as of the neutron allows us to perform an isospin decomposition. Further investigations with real photons are scheduled at SLAC, JLAB, SPRING-8, LEGS and GRAAL. The integral (sum) of the GDH sum rule can be generalized to the case of virtual photons. This allows us to establish a Q2 dependency and to study the transition to the perturbative regime of QCD. Ultimately, the GDH sum rule can be related to the Bjorken and the Ellis-Jaffe sum rule. This transition is the subject of several experiments e.g. at JLAB for the resonance region and of the HERMES experiment at DESY for higher Q2. This contribution covers the status of theory concerning the GDH sum rule as well as the experimental approaches and their results for the absorption of real and virtual photons. We point out that the so-called No-Subtraction hypothesis, often considered the weakest part of the derivation of the GDH sum rule, in fact follows from unitarity and does not impair the fundamental character of the GDH sum rule. The experimental data verify the GDH sum rule for the proton at the level of 8% including the systematic uncertainties from extrapolations to unmeasured energy regions. For the GDH sum rule on the neutron and the isovector case we find unexpected contributions at photon energies above 1 GeV.

Preface: Memories of Maurice Jacob (1933-2007) Proceedings of the Maurice Jacob Memorial Meeting (CERN, 11 September 2007) Memories of Maurice Jacob (1933-2007) Proceedings of the Maurice Jacob Memorial Meeting (CERN, 11 September 2007)  

NASA Astrophysics Data System (ADS)

Maurice Jacob passed away unexpectedly on 2 May 2007. Soon after the terrible news arrived, it was thought appropriate to organize a memorial meeting at CERN. The meeting took place on 11 September 2007, and a large number of friends and colleagues participated in the event. The idea was to have brief presentations on the many scientific activities in which Maurice had been engaged, to provide a sketch of his personal trajectory. We also had spontaneous anecdotes and recollections from the audience which, unfortunately, did not make it into this special issue but enriched all of us present. The meeting took place in an afternoon, hence we were faced with the difficult task of selecting from the many presentations that could have been made by his colleagues and collaborators. The end results are the papers contained in this special issue. They provide a short overview of the breadth and depth of Maurice's physics, on the one hand, and of his deep commitment to European and world physics and to the interface between science and society, on the other hand. The first two talks were given by his fellow students and life-long friends Claude Cohen-Tannoudji and Robert Pick. These were mostly personal recollections, less focussed on scientific issues per se but reminding us how Maurice grew into the renowned scientist he later became. Cecilia Jarlskog, a longtime collaborator and friend, provided us with a beautiful view of the wonderfully multifaceted activities Maurice was able to accomplish. Peter Landshoff also spoke about his more than 35 years of personal and scientific interaction with Maurice. The talks presented during the second part of the meeting went a bit more into the technical details of the wide spectrum of scientific activities pursued by Maurice. We had contributions by Helmut Satz (whose transparencies were kindly presented by Urs Wiedemann) and Ulrich Heinz, with the closing talk presented by John Ellis. We have lost a great friend and an excellent physicist. But Maurice's scientific and social contributions, his personal example and his memory will remain with us. We were fortunate to have with us at the meeting his wife Lise and their children, Thierry, Daniel, Francis and Irene. We dedicate this issue to them. We express our deep gratitude to John Ellis, Andre Martin and Anne-Marie Perrin for their invaluable help in preparing all aspects of the meeting.

Estimating rheological properties of lava flows using high-resolution time lapse imaging  

NASA Astrophysics Data System (ADS)

During effusive eruptions, property and infrastructure can be threatened by lava flow inundation. In order to maximise the effectiveness of the response to such an event, it is necessary to be able to reliably forecast the area that will be affected. One of the major controls on the advance of a lava flow is its rheology, which is spatially and temporally variable, and depends on many underlying factors. Estimating the rheological properties of a lava flow, and the change in these over space and time is therefore of the utmost importance. Here we report estimates of rheological properties made from geometric and velocity measurements on integrated topographic and image data using the method of Ellis et al. (2004) (Ellis B, Wilson L & Pinkerton H (2004) Estimating the rheology of basaltic lava flows. Lunar & Planetary Science XXXV Abst. 1550). These are then compared to the viscosity predicted from composition and temperature by the GRD model (Giordano D, Russell JK, & Dingwell DB (2008) Viscosity of Magmatic Liquids: A Model. Earth & Planetary Science Letters, 271, 123-134). During the 13 May 2008 - 6 July 2009 eruption of Mt Etna, Sicily, lava flows were emplaced into the Valle del Bove, reaching a maximum length of >6 km. Towards the end of the eruption, multiple channelized aa flows were active simultaneously, reaching tens to hundreds of metres in length. Flow lifetimes were of the order hours to days. In the last month of the eruption, we installed a Canon EOS 450D camera at Pizzi Deneri, on the north side of the Valle del Bove, to collect visible images at 15-minute intervals. On one day, topographic data (using a Riegl LPM-321 terrestrial laser scanner) and thermal images (using a FLIR Thermacam S40) were also collected from this location. The fronts of some of the larger flows were tracked through the time lapse image sequence. Using knowledge of the camera imaging geometry, the pixel tracks were reprojected onto the topographic surface to determine flow advance in 3-D geographic coordinates. Integrating the tracking results with the topographic data allows flow lengths and velocities to be extracted. Using these parameters together with estimates of the flow width and thickness, we estimate effective yield strengths, apparent viscosities and Gratz numbers for the tracked flows. We then evaluate the success of this method using predicted viscosities from the GRD model of Giordano et al. (2008).

A precision measurement of the spin structure of the proton at SLAC  

NASA Astrophysics Data System (ADS)

E143 at SLAC Endstation A performed deep-inelastic scattering measurements of polarized electrons from polarized protons and deuterons within cryogenic 15NH3 and 15ND3, respectively. Data were taken at incident energies of 29.1, 16.2 and 9.7 GeV, and covered the kinematical range x > 0.03 and 0.3 < Q 2 < 12 (GeV/c)2. The scattered electrons were detected by two spectrometers at angles of 4.5° and 7.0°. From these data, the spin-dependent structure functions gp1(x,Q2) and gd1(x,Q2) were determined. This dissertation describes the experiment, with emphasis on the results on the proton spin structure. The integral of g1 over the range 0 < x < 1 was found to be Gp1 = 0.130 +/- 0.003 +/- 0.008 for the proton and Gd1 = 0.044 +/- 0.003 +/- 0.004 for the deuteron. Both values are in agreement with world data, and violate the Ellis-Jaffe sum rule by more than 3 standard deviations. The neutron structure function was obtained by combining proton and deuteron results, giving Gn1 = -0.035 +/- 0.007 +/- 0.010. From this the integral Gp1 - Gn1 followed, yielding 0.165 +/- 0.009 +/- 0.016 at Q2 = 3 (GeV/c)2, in agreement with the Bjorken sum rule to within one standard deviation. The Q2-dependence of the ratio g 1/F1 was determined to be small for Q2 > 1 (GeV/c)2, validating the assumption of no Q2-dependence used in obtaining the integrals. A small rise with increasing Q2 was seen in the ratio for Q2 < 1 (GeV/c) 2, however. The total quark contribution to the spin was found to be ?q = 0.28 +/- 0.09 for the proton, and ? q = 0.32 +/- 0.05 for the deuteron. Furthermore, a large negative spin contribution from the strange sea quarks was measured for both nucleons, giving ?s = -0.10 +/- 0.03 and ? s = -0.09 +/- 0.02 for the proton and deuteron respectively, in contradiction to the Ellis-Jaffe assumption of no polarized strange sea.

Les cooperatives et l'electrification rurale du Quebec, 1945--1964  

NASA Astrophysics Data System (ADS)

Cette these est consacree a l'histoire de l'electrification rurale du Quebec, et, plus particulierement, a l'histoire des cooperatives d'electricite. Fondees par vagues successives a partir de 1945, les cooperatives rurales d'electricite ont ete actives dans plusieurs regions du Quebec et elles ont electrifie une partie significative des zones rurales. Afin de comprendre le contexte de la creation des cooperatives d'electricite, notre these debute (premiere partie) par une analyse du climat sociopolitique des annees precedant la naissance du systeme cooperatif d'electrification rurale. Nous y voyons de quelle facon l'electrification rurale devient progressivement, a partir de la fin des annees 1920, une question d'actualite a laquelle les divers gouvernements qui se succedent tentent de trouver une solution, sans engager---ou si peu---les fonds de l'Etat. En ce sens, la premiere etatisation et la mise sur pied d'Hydro-Quebec, en 1944, marquent une rupture quant au mode d'action privilegie jusque-la. La nouvelle societe d'Etat se voit cependant retirer son mandat d'electrifier le monde rural un an apres sa fondation, car le gouvernement Duplessis, de retour au pouvoir, prefere mettre en place son propre modele d'electrification rurale. Ce systeme repose sur des cooperatives d'electricite, soutenues par un organisme public, l'Office de l'electrification rurale (OER). L'OER suscite de grandes attentes de la part des ruraux et c'est par centaines qu'ils se manifestent. Cet engouement pour les cooperatives complique la tache de l'OER, qui doit superviser de nouvelles societes tout en assurant sa propre organisation. Malgre des hesitations et quelques delais introduits par un manque de connaissances techniques et de personnel qualifie, les commissaires de l'OER se revelent perspicaces et parviennent a mettre sur pied un systeme cooperatif d'electrification rurale qui produit des resultats rapides. Il leur faudra cependant compter sur l'aide des autres acteurs engages dans l'electrification, les organismes publics et les compagnies privees d'electricite. Cette periode de demarrage et d'organisation, traitee dans la deuxieme partie de la these, se termine en 1947-48, au moment ou l'OER et les cooperatives raffermissent leur maitrise du systeme cooperatif d'electrification rurale. Les annees 1948 a 1955 (troisieme partie de these) correspondent a une periode de croissance pour le mouvement cooperatif. Cette partie scrute ainsi le developpement des cooperatives, les vastes chantiers de construction et l'injection de millions de dollars dans l'electrification rurale. Cette troisieme partie prend egalement acte des premiers signes que quelque chose ne va pas si bien dans le monde cooperatif. Nous y verrons egalement les ruraux a l'oeuvre: comme membres, d'abord, mais aussi en tant que benevoles, puis a l'emploi des cooperatives. La quatrieme et derniere partie, les annees 1956 a 1964, aborde les changements majeurs qui ont cours dans l'univers cooperatif; il s'agit d'une ere nouvelle et difficile pour le mouvement cooperatif, dont les reseaux paraissent inadaptes aux changements de profil de la consommation d'electricite des usagers. L'OER sent alors le besoin de raffermir son controle des cooperatives, car il pressent les problemes et les defis auxquels elles auront a faire face. Notre etude se termine par l'acquisition des cooperatives par Hydro-Quebec, en 1963-64. Fondee sur des sources riches et variees, notre demarche propose un eclairage inedit sur une dimension importante de l'histoire de l'electricite au Quebec. Elle permet, ce faisant, de saisir les rouages et l'action de l'Etat sous un angle particulier, avant sa profonde transformation amorcee au cours des annees 1960. De meme, elle apporte quelques cles nouvelles pour une meilleure comprehension de la dynamique des milieux ruraux de cette periode.

Gas-liquid equilibrium in a CO{sub 2}-MDEA-H{sub 2}O system and the effect of piperazine on it  

SciTech Connect

Aqueous N-methyldiethanolamine (MDEA) solutions are widely used for removal of the acid gas (H{sub 2}S and CO{sub 2}) from natural gas synthesis and refinery gas streams. Solubility data of CO{sub 2} and vapor pressure of water in 3.04--4.28 kmol/m{sup 3} aqueous N-methyldiethanolamine (MDEA) solutions were obtained at temperatures ranging from 40 to 100 C and CO{sub 2} partial pressures ranging from 0.876 to 1,013 kPa. A thermodynamic model was proposed and used for predicting CO{sub 2} solubility and water vapor pressure. An enthalpy change of absorption of CO{sub 2} in 4.28 kmol/m{sup 3} MDEA solution was estimated. The effect of piperazine (PZ) concentration on CO{sub 2} loading in MDEA solutions was determined at piperazine concentration ranging from 0 to 0.515 kmol/m{sup 3}. The results show that piperazine is beneficial to the CO{sub 2} loading. The equilibrium partial pressure of piperazine in the PZ-MDEA-H{sub 2}O system was measured in an Ellis Cell. Results show that the PZ-MDEA-H{sub 2}O system is a typical negative deviation system, with the strength of deviation decreasing with MDEA solutions.

Patterns of Racial Diversity and Segregation in the United States: 1990-2010*  

PubMed Central

The growing ethnic and racial diversity of the United States is evident at all spatial scales. One of the striking features of this new mixture of peoples, however, is that this new diversity often occurs in tandem with racial concentration. This article surveys these new geographies from four points of view: the nation as a whole, states, large metropolitan areas, and neighborhoods. The analysis at each scale relies on a new taxonomy of racial composition that simultaneously appraises both diversity and the lack thereof (Holloway, Wright, and Ellis 2012). Urban analysis often posits neighborhood racial segregation and diversity as either endpoints on a continuum of racial dominance or mirror images of one another. We disturb that perspective and stress that segregation and diversity must be jointly understood—they are necessarily related, although not as inevitable binary opposites. Using census data from 1990, 2000, and 2010, the research points to how patterns of racial diversity and dominance interact across varying spatial scales. This investigation helps answer some basic questions about the changing geographies of racialized groups, setting the stage for the following articles that explore the relationship between geography and the participation of underrepresented groups in higher education.

Regulation of Phytoalexin Synthesis in Jackbean Callus Cultures  

PubMed Central

Jackbean, Canavalia ensiformis (L.), callus tissues synthesized the phytoalexin, medicarpin (3-hydroxy-9-methoxypterocarpan), when treated with spore suspensions of Pithomyces chartarum (Berk. and Curt.) M. B. Ellis, a nonpathogen of jackbean. Medicarpin was isolated from treated callus tissue and identified by its ultraviolet and mass spectra. The minimum spore concentration found to elicit medicarpin synthesis after 26 hours was 1 × 105 spores/ml; levels of medicarpin in callus tissue increased linearly up to 1 × 107 spores/ml, indicating that the recognition sites for presumed elicitors were not saturated. Medicarpin was first detected in callus treated with 1 × 107 spores/ml, 6 to 12 hours after application, and the concentration reached a maximum at 48 hours, slowly declining thereafter to 72 hours. In callus treated with 3.15 mm HgCl2, medicarpin concentrations were also maximum by 48 hours. Phenylalanine ammonia-lyase (EC 4.3.1.5) activity increased 2-fold in spore-treated callus after 36 hours. Isoliquiritigenin, daidzein, and genistein o-methyltransferase (EC 2.1.1.6) activities were increased 3- to 4-fold in treated callus. Caffeic acid and naringenin were more efficient substrates for o-methyltransferase activity than the other flavonoids or apigenin, but there was no increase in these o-methyltransferase activities in spore-treated callus. The phytoalexin response in this callus tissue culture system compares well with natural plant systems and should be an excellent system for investigating regulation of phytoalexin synthesis.

8-aminoquinolines effective against Pneumocystis carinii in vitro and in vivo.  

PubMed Central

The activities of 25 8-aminoquinolines were compared in tests assessing the ability of the compounds to inhibit the growth of Pneumocystis carinii in culture. Six compounds were effective at or below 0.03 microM: CDRI 80/53, NSC19894, NSC305805, NSC305812, WR182234, and primaquine. Four others were effective at between 0.2 and 0.03 microM: NSC305835, WR225448, WR238605, and WR242511. Fourteen drugs were also tested in a standard model of P. carinii pneumonia in rats at daily doses of 2 mg/kg of body weight in drinking water. CDRI 80/53, NSC305805, NSC305835, and WR225448 were extremely effective in the animal model. The effectiveness of WR238605, WR242511, and primaquine in the rat model has been reported elsewhere (M. S. Bartlett, S. F. Queener, R. R. Tidwell, W. K. Milhouse, J. D. Berman, W. Y. Ellis, and J. W. Smith, Antimicrob. Agents Chemother. 35:277-282, 1991). The length of the alkyl chain separating the nitrogens in the substituent at position 8 of the quinoline ring was a strong determinant of anti-P. carinii activity.

Closing of venus flytrap by electrical stimulation of motor cells.  

PubMed

Electrical signaling and rapid closure of the carnivorous plant Dionaea muscipula Ellis (Venus flytrap) have been attracting the attention of researchers since XIX century, but the exact mechanism of Venus flytrap closure is still unknown. We found that the electrical stimulus between a midrib and a lobe closes the Venus flytrap leaf by activating motor cells without mechanical stimulation of trigger hairs. The closing time of Venus flytrap by electrical stimulation of motor cells is 0.3 s, the same as mechanically induced closing. The mean electrical charge required for the closure of the Venus flytrap leaf is 13.6 microC. Ion channel blockers such as Ba(2+), TEACl as well as uncouplers such as FCCP, 2,4-dinitrophenol and pentachlorophenol dramatically decrease the speed of the trap closing. Using an ultra-fast data acquisition system with measurements in real time, we found that the action potential in the Venus flytrap has a duration time of about 1.5 ms. Our results demonstrate that electrical stimulation can be used to study mechanisms of fast activity in motor cells of the plant kingdom. PMID:19516982

Energetics and forces of the Dionaea muscipula trap closing.  

PubMed

The Venus flytrap is the most famous carnivorous plant. The electrical stimulus between a midrib and a lobe closes the Venus flytrap upper leaf in 0.3s without mechanical stimulation of trigger hairs. Here we present results for direct measurements of the closing force of the trap of Dionaea muscipula Ellis after mechanical or electrical stimulation of the trap using the piezoelectric thin film or Fuji Prescale indicating sensor film. The closing force was 0.14N and the corresponding pressure between rims of two lobes was 38 kPa. We evaluated theoretically using the Hydroelastic Curvature Model and compared with experimental data velocity, acceleration and kinetic energy from the time dependencies of distance between rims of lobes during the trap closing. The Charge Stimulation Method was used for trap electrostimulation between the midrib and lobes. From the dependence of voltage between two Ag/AgCl electrodes in the midrib and one of the lobes, we estimated electrical charge, current, resistance, electrical energy and electrical power dependencies on time during electrostimulation of the trap.

Elastic models of the fast traps of carnivorous Dionaea and Aldrovanda.  

PubMed

The carnivorous aquatic waterwheel plant (Aldrovanda vesiculosa L.) and the closely related terrestrial Venus flytrap (Dionaea muscipula Sol. ex J. Ellis) both feature elaborate snap-traps, which shut after reception of an external mechanical stimulus by prey animals. Although Aldrovanda is usually considered a miniature aquatic Dionaea, the shutting mechanisms of the two plants differ quite markedly. The fast shutting of Aldrovanda is indeed based on a simple swelling or shrinking mechanism, while the movement of Dionaea's traps is accelerated by the snap-buckling of the lobes. The purpose of this Brief Report is to describe several key improvements to the elastic models that have recently been introduced to elucidate these movements [Poppinga and Joyeux, Phys. Rev. E 84, 041928 (2011)]. In particular, a precise mechanism for the action of the motor cells of Aldrovanda is proposed, the facts that the opening of the leaves of Dionaea is an irreversible mechanism based on growth and that the strain field is anisotropic and much smaller on the inner than on the outer surface of the leaves during shutting are taken properly into account, and a more accurate formula for calculating mean curvatures is used. The improvements brought to the model are described in detail and the physical consequences of these improvements are discussed. PMID:24125387

Different mechanics of snap-trapping in the two closely related carnivorous plants Dionaea muscipula and Aldrovanda vesiculosa.  

PubMed

The carnivorous aquatic waterwheel plant (Aldrovanda vesiculosa L.) and the closely related terrestrial venus flytrap (Dionaea muscipula Sol. ex J. Ellis) both feature elaborate snap-traps, which shut after reception of an external mechanical stimulus by prey animals. Traditionally, Aldrovanda is considered as a miniature, aquatic Dionaea, an assumption which was already established by Charles Darwin. However, videos of snapping traps from both species suggest completely different closure mechanisms. Indeed, the well-described snapping mechanism in Dionaea comprises abrupt curvature inversion of the two trap lobes, while the closing movement in Aldrovanda involves deformation of the trap midrib but not of the lobes, which do not change curvature. In this paper, we present detailed mechanical models for these plants, which are based on the theory of thin solid membranes and explain this difference by showing that the fast snapping of Aldrovanda is due to kinematic amplification of the bending deformation of the midrib, while that of Dionaea unambiguously relies on the buckling instability that affects the two lobes.

Rat brain expresses an alternatively spliced form of the dihydropyridine-sensitive L-type calcium channel alpha 2 subunit.  

PubMed

We have cloned and sequenced a cDNA (rB-alpha 2) encoding an alpha 2 subunit of the voltage-sensitive L-type calcium channel (dihydropyridine receptor) of rat brain. The cDNA (3823 base pairs) encodes a protein of 1091 amino acids with a Mr of 123,822. The deduced amino acid sequence of rB-alpha 2 cDNA is highly similar (95% amino acid identity) to that of rabbit skeletal muscle alpha 2 subunit. The rB-alpha 2 protein is distinct from the previously cloned skeletal muscle alpha 2-subunit protein [Ellis, S. B., Williams, M. E., Ways, N. R., Brenner, R., Sharp, A. H., Leung, A. T., Campbell, K. P., McKenna, E., Koch, W., Hui, A., Schwartz, A. & Harpold, M. M. (1988) Science 241, 1661-1664] because it contains an insertion of 7 amino acid residues and a deletion of a 19-amino acid segment between putative transmembrane domains 1 and 2. We show that the rB-alpha 2 and skeletal muscle alpha 2-subunit transcripts are the variants produced by alternative splicing of the primary transcript and that they are differentially expressed in brain and skeletal muscle, respectively.

A global analysis of inclusive diffractive cross sections at HERA  

NASA Astrophysics Data System (ADS)

We describe the most recent data on the diffractive structure functions from the H1 and ZEUS Collaborations at HERA using four models. First, a Pomeron Structure Function (PSF) model, in which the pomeron is considered as an object with parton distribution functions. Then, the Bartels-Ellis-Kowalski-Wüsthoff (BEKW) approach is discussed, assuming the simplest perturbative description of the pomeron using a two-gluon ladder. A third approach, the Bialas-Peschanski (BP) model, based on the dipole formalism is then described. Finally, we discuss the Golec-Biernat-Wüsthoff (GBW) saturation model which takes into account saturation effects. The best description of all available measurements can be achieved with either the PSF based model or the BEKW approach. In particular, the BEKW prediction allows to include the highest ? measurements, which are dominated by higher twists effects and provide an efficient and compact parametrisation of the diffractive cross section. The two other models also give a good description of cross section measurements at small x with a small number of parameters. The comparison of all predictions allows us to identify interesting differences in the behavior of the effective pomeron intercept and in the shape of the longitudinal component of the diffractive structure functions. In this last part, we present some features that can be discriminated by new experimental measurements, completing the HERA program.

The linguistically aware teacher and the teacher-aware linguist.  

PubMed

This review evaluates issues of teacher linguistic knowledge relating to their work with children with speech, language and communication difficulties (SLCD). Information is from Ellis and McCartney [(2011a). Applied linguistics and primary school teaching. Cambridge: Cambridge University Press], a state-of-the-art text deriving from a British Association of Applied Linguistics/Cambridge University Press expert seminar series that details: linguistic research underpinning primary school curricula and pedagogy; the form of linguistic knowledge useful for teachers supporting children with SLCD in partnership with speech and language therapists; and how and when teachers acquire and learn to apply such knowledge. Critical analysis of the options presented for teacher learning indicate that policy enjoinders now include linguistic application as an expected part of teachers' professional knowledge, for all children including those with SLCD, but there is a large unmet learning need. It is concluded that there is a role for clinical linguists to disseminate useable knowledge to teachers in an accessible format. Ways of achieving this are considered. PMID:23621402

Atlantic Multidecadal Oscillation recorded in fossil corals during the last Interglacial  

NASA Astrophysics Data System (ADS)

The Atlantic Multidecadal Oscillation (AMO) is a mode of sea surface temperature variability occurring in the North Atlantic Ocean, whose warm phase correlates strongly with Atlantic hurricane activity. While support for this mode originates in historical observations and models, controversy exists with regard to the attribution of sea surface temperature change to natural or anthropogenic forcing. Previously, we showed that long-lived colonies of the massive Caribbean coral Siderastrea siderea (Ellis & Solander, 1786) on the Yucatan Peninsula capture AMO-like variability in their annual growth bands (Vásquez-Bedoya et al., 2012) allowing us to extend the record of Atlantic multidecadal variability back to 1775 AD. Here we report an analysis of skeletal growth bands of a fossil coral of the same species, dated by U-series (122.24±0.19 kyr) to the Last Interglacial (LIG). MultiTaper spectral analysis of the LIG coral record reveals significant concentrations of power (99% confidence level) at intervals centered at 45-67 and 50-67 years respectively, consistent with the AMO spectrum, which is centered in intervals of 60-70 years. Thus our analysis provides the first evidence of AMO mode during the LIG and supports the hypotheses of a persistent, naturally-forced multidecadal mode of SST variability in the North Atlantic.

One- or two-plate fixation of mandibular angle fractures?  

PubMed

Standard treatment of mandibular angle fractures with miniplates, according to the recommendations of Champy et al. (1976), consists of fixation with one plate at the superior border of the mandible ventral to the external oblique line. In certain constellations, a second miniplate at the lower mandibular margin may provide additional stability. In contrast, extremely high complication rates following two-plate fixation of mandibular angle fractures were reported by Ellis and Walker (1994). In a prospective randomized study, 31 consecutive patients were treated with 2.0 mm (mini) plates (Synthes Co., Switzerland). One group was treated with one plate, the other one with two plates. In none of the patients was intermaxillary immobilization used. Follow-up was performed 6 months postoperatively, consisting of clinical and radiographic examination. No significant differences (P = 0.74 for infection, and P = 1.0 for occlusal and postoperative sensory disturbance) in postoperative short- or long-term complications were found between the two groups. The results are compared with our experimental investigations presented at the annual congress of the Germany Society of Oral and Maxillofacial Surgery, 1995. Two-plate fixation may not offer advantages over single-plate fixation in general. However, individual fracture constellations may benefit from variation in plate(s) localization. Factors contributing to complications in mandibular angle fractures are discussed. PMID:9234097

Technical Site Information: Planning group of the Directorate and Conventional Construction Division  

SciTech Connect

This document presents the technical site information for the Superconducting Super Collider project. The Ellis County, Texas site was selected by the Department of Energy in 1989. After assembling the initial staff at temporary facilities in Dallas, the SSC Laboratory began site-specific design work. The resulting design for the SSC accelerators, experimental areas, and laboratory facilities were described in the Site-Specific Conceptual Design Report of July 1990. Since then, design specifications for the technical components and conventional facilities have been formulated. In fact, a very significant amount of surface and underground construction has been initiated and many buildings have been completed. Testing of prototypes for most technical components is advanced. The construction phase of the SSC project is approximately 20% complete. At this time, it is appropriate to capture the conventional design work which has taken place since 1990. This documents records regional and physical information used in site studies, summarizes the site studies for conventional facilities, and presents site layouts for buildings and utilities as they would have been at the end of the construction project. As such, this documents summarizes and complements the work of many groups in the SSC laboratory, the Texas National Research Laboratory Commission (TNRLC), and several subcontractors to the SSC project. The document contains extensive references to their work contained in other drafts and final reports. In particular, it borrows heavily from the Site Development Plan (released in draft form in January, 1992) which has, to date, guided aspects of site development.

The Superconducting Super Collider (SSC) project will be constructed for the United States Department of Energy at a competitively-selected site in Ellis County, Texas, about 30 mile (50 km) south of the central business district of Dallas. The injector system and main collider ring will be housed in 70 mile (110 km) of tunnel, and the project will include additional shafts and underground enclosures with clear spans up to 30 ft (10 m) at depths of more than 250 ft (75 m). The first tunnel segment to be designed and constructed will include approximately 5.9 mile (9.4 km) of 12 ft (3.7 m) finished internal diameter tunnel, four shafts up to 55 ft (16.8 m) diameter, and various connecting tunnels and adits. Construction will be in weak rock lithologies, including mudstones, marls, and chalks with compressive strengths typically between 300 and 2500 psi (2.0 and 17.2 MPa). Design is underway, with an expected bid date before the end of 1990, and with start of construction following in the spring of 1991. 7 refs., 8 figs., 1 tab.

Altered Endoplasmic Reticulum Calcium Pump Expression during Breast Tumorigenesis  

PubMed Central

Endoplasmic reticulum calcium homeostasis is involved in several essential cell functions including cell proliferation, protein synthesis, stress responses or secretion. Calcium uptake into the endoplasmic reticulum is performed by Sarco/Endoplasmic Reticulum Calcium ATPases (SERCA enzymes). In order to study endoplasmic reticulum calcium homeostasis in situ in mammary tissue, in this work SERCA3 expression was investigated in normal breast and in its benign and malignant lesions in function of the cell type, degree of malignancy, and histological and molecular parameters of the tumors. Our data indicate, that although normal breast acinar epithelial cells express SERCA3 abundantly, its expression is strongly decreased already in very early non-malignant epithelial lesions such as adenosis, and remains low in lobular carcinomas. Whereas normal duct epithelium expresses significant amounts of SERCA3, its expression is decreased in several benign ductal lesions, as well as in ductal adenocarcinoma. The loss of SERCA3 expression is correlated with Elston-Ellis grade, negative hormone receptor expression or triple negative status in ductal carcinomas. The concordance between decreased SERCA3 expression and several histological, as well as molecular markers of ductal carcinogenesis indicates that endoplasmic reticulum calcium homeostasis is remodeled during tumorigenesis in the breast epithelium.

Cricoid pressure: a review of the literature.  

PubMed

Aspiration pneumonitis (Mendelson's syndrome) is universally accepted as a complication of general anaesthesia. According to Ellis et al (2007) death from aspiration was first described by Simpson in 1848, and it was not until 1946 that Mendelson identified acid aspiration in a significant number of obstetric patients undergoing facemask anaesthesia. The advent of techniques to secure the airway, through the use of airway adjuncts has gone some way to reduce the likely incidence of aspiration in today's perioperative arena. The positive outcome for patients is corroborated by Neilipovitz & Crosby (2007) who report aspiration as a rare complication with an overall incidence of 1:2,000-3,000. As Ewart (2007) highlights, Mendelson's syndrome is due to pharmacological effects at a molecular level which occur in the airway tissues and are caused by the use of induction and neuromuscular blocking agents. The resultant loss of consciousness and consequent diminished protective airway reflexes ultimately places the patient at risk until their airway is secured. Preventative measures to protect the lung from contamination with gastric contents, for example preoperative fasting, are therefore instigated prior to securing the airway. PMID:21874987

Microlensed image centroid motions by an exotic lens object with negative convergence or negative mass  

NASA Astrophysics Data System (ADS)

Gravitational lens models with negative convergence inspired by modified gravity theories, exotic matter, and energy have been recently examined in such a way that a static and spherically symmetric modified spacetime metric depends on the inverse distance to the nth power (n=1 for Schwarzschild metric, n=2 for Ellis wormhole, and n?1 for an extended spherical distribution of matter such as an isothermal sphere) in the weak-field approximation. Some of the models act as if a convex lens, whereas the others are repulsive on light rays like a concave lens. The present paper considers microlensed image centroid motions by the exotic lens models. Numerical calculations show that, for large n cases in the convex-type models, the centroid shift from the source position might move on a multiply connected curve like a bow tie, while it is known to move on an ellipse for the n=1 case and to move on an oval curve for n=2. The distinctive feature of the microlensed image centroid may be used for searching (or constraining) localized exotic matter or energy with astrometric observations. It is shown also that the centroid shift trajectory for concave-type repulsive models might be elongated vertically to the source motion direction like a prolate spheroid, whereas that for convex-type models such as the Schwarzschild one is tangentially elongated like an oblate spheroid.

We model the supermassive Galactic center of the Milky Way Galaxy as a strongly naked singularity lens described by the Janis-Newman-Winicour metric. This metric has an ordinary mass and massless scalar charge parameters. For very accurate results, we use the Virbhadra-Ellis lens equation for computations. The Galactic center serving as a gravitational lens gives rise to four images: two images on the same side as the source and two images on the opposite side of the source from the optic axis. We compute positions and time delays of these images for many values of the angular source position. The time delays of primary images decrease with an increase in angular source position and are always negative. The time delays of the other three images are negative for a small angular source position; however, they increase with an increase in the angular source position. Such observations would support strongly naked singularity interpretation of the Galactic center, and would disprove the cosmic censorship hypothesis proposed by Roger Penrose as well as a weaker version by Virbhadra that allows the existence of weakly, but not marginally, and strongly naked singularities.

Coastal-inland solar radiation difference study. Final report  

SciTech Connect

The purpose of this study was to quantify the characteristics of solar insolation in the coastal zone and to determine the effect of the sea breeze circulation on the global insolation. In order to satisfy these objectives, a six station sampling network was established in the coastal plain of southeastern North Carolina, where previous evidence has indicated that the sea breeze circulation is almost a daily occurrence from late May through October. Three sites (Sloop Point, Onslow Beach, and Cape Fear Technical Institute (CFTI)) were located near the coast (coastal sites) to assess the insolation at the coast. A site (Clinton) was located in an area seldom affected by the sea breeze (about 100 km from the coast). Two additional sites, Wallace and Ellis Airport, located between the coastal sites and the control site, were to be used to assess the transient impact of the sea breeze upon the insolation. Pyranometers were located at each site to measure the global insolation. Direct normal insolation measured by a pyrheliometer and ultraviolet radiation measured by uv radiometers were observed at the Sloop Point and Clinton sites only. Data were collected during the calendar year 1978. The results of the study indicated that the global insolation had greater variability over the network during the summer season (June, July, and August). During the summer, there was a systematicdiurnal variation of the difference in global insolation between the inland and the coastal sites.

A study of the autoxidation of some unsaturated fatty acid methyl esters using Fourier transform Raman spectroscopy  

NASA Astrophysics Data System (ADS)

Near-infrared Fourier transform Raman and Fourier transform infrared spectroscopy have been used to investigate the chemical changes taking place during the curing reaction of several fatty acid methyl esters, which are used for modelling processes in the autoxidation of alkyd resin coatings. We have studied methyl oleate, methyl linoleate, and methyl linolenate in an attempt to monitor the degree of unsaturation within the fatty acid methyl esters (FAMES) during the complex autoxidation/polymerisation reaction that takes place once the paint system is coated onto a substrate and exposed to the atmosphere. The peaks around 1655 cm -1 have been assigned as follows: to the trans isomer at 1670 cm -1, the cis isomer at 1655 cm -1 and the conjugated structure at 1640 cm -1 [B. Schrader, Raman/Infrared Atlas of Organic Compounds (2nd Edn), VCH, Weinheim (1989); J. K. Abenyega, M. Claybourn and G. Ellis, in preparations]. Raman spectra for the cure of methyl linoleate after 24 h show several interesting features, suggesting the formation of a highly conjugated cyclic structure. Current theories about the mechanism for the autoxidation of methyl linoleate make no mention of this aromatic product.

Optimization of data acquisition and processing in Carr-Purcell-Meiboom-Gill multiple quantum magic angle spinning nuclear magnetic resonance  

NASA Astrophysics Data System (ADS)

Data acquisition using the Carr-Purcell-Meiboom-Gill (CPMG) train of ? pulses has been recently explored in multiple quantum magic angle spinning (MQMAS) nuclear magnetic resonance of half-integer quadrupolar nuclei [T. Vosegaard, F. H. Larsen, H. J. Jakobsen, P. D. Ellis, and N. C. Nielsen, J. Am. Chem. Soc. 119, 9055 (1997)]. Significant increase of sensitivity can be obtained by using this technique at the expense of spectral definition, as the spectrum transforms into a manifold of narrow sidebands. A detailed analysis of the CPMG method, with emphasis on the MQMAS experiment, is presented. The MQ-QCPMG-MAS approach is adapted to spin-5/2 nuclei. Several numerical methods of data treatment are shown that allow for improvement of the definition of the sideband envelope, reconstruction of the standard line shape, and improvement of S/N ratio via optimized filtering. Theoretical and experimental estimates of signal enhancement through proper acquisition and processing of MQ-QCPMG-MAS data are given.

Visual Stratigraphic Correlation and Anaglyph 3-D Visualizations Using GigaPan Imagery: Examples from Western Kansas  

NASA Astrophysics Data System (ADS)

GigaPan images of outcrop, quarry, and roadcut exposures have been captured and are being used to test the efficacy of a novel visual comparison technique in addressing issues of stratigraphic correlation of sub- units within the Upper Cretaceous Niobrara Formation in Rooks, Ellis, Gove, and Trego Counties in northwest Kansas. Through the use of side-by-side implementations of the web-based GigaPan Flash viewer, distinctive individual layers and stratigraphic sequences can be matched in a highly intuitive visual manner. Incorporating adequate quantitative measures of scale is a challenge that remains to be solved before high precision correlation can be done with GigaPan imagery, however semi-quantitative and qualitative preliminary results suggest that this device may become a powerful research tool. Application of the visual correlation technique to the teaching of stratigraphic correlation concepts in the classroom offers a novel and interactive way for students to experience the joy of discovery in a virtual field environment. A method for creating anaglyph GigaPan images with the current GigaPan robot will also be described; the resulting images represent another way to significantly enhance classroom-based virtual field experiences.

On the anomalous large-scale flows in the Universe  

NASA Astrophysics Data System (ADS)

Recent combined analyses of the CMB and galaxy cluster data reveal unexpectedly large and anisotropic peculiar velocity fields at large scales. We study cosmic models with included vorticity, acceleration and total angular momentum of the Universe in order to understand the phenomenon. The Zel’dovich model is used to mimic the low redshift evolution of the angular momentum. Solving coupled evolution equations of the second order for density contrast in corrected Ellis-Bruni covariant and gauge-invariant formalism one can properly normalize and evaluate integrated Sachs-Wolfe effect and peculiar velocity field. The theoretical results compared to the observations favor a much larger matter content of the Universe than that of the concordance model. Large-scale flows appear anisotropic with dominant components placed in the plane perpendicular to the axis of vorticity (rotation). The integrated Sachs-Wolfe term has a negative contribution to the CMB fluctuations for the negative cosmological constant and it can explain the observed small power of the CMB TT spectrum at large scales. The rate of the expansion of the Universe may be substantially affected by the angular momentum if its magnitude is large enough.

New data on the Albian-Cenomanian radiolarians from the Karai Formation (South India)  

NASA Astrophysics Data System (ADS)

Radiolarians from the lower part of the Karai Formation (upper Albian-middle Cenomanian) are studied in detail for the first time. Among over 50 radiolarian species identified in the formation, there are Acaeniotyle amplissima (Foreman), Savaryella novalensis (Squinabol), S. quadra (Foreman), Vitorfus campbelli Pessagno, Archaeodictyomitra montisserei (Squinabol), Holocryptocanium barbui Dumitrica, Pseudoeucyrtis sp. cf. Ps. spinosa (Squinabol), Stichomitra communis Squinabol, Tubilustrionella transmontanum (O'Dogherty), and others. The discovered radiolarians are divided into the Halesium triacanthum-Orbiculiforma nevadaenis (late Albian-early Cenomanian), Crucella latum-Cryptamphorella micropora (late Albian?-early Cenomanian), and Becus sp. B-Godia concava (terminal Albian-middle Cenomanian) assemblages. In general, the Albian-Cenomanian radiolarians of South India are comparatively less diverse than the concurrent assemblages of the Mediterranean region and California. In taxonomic composition and morphological peculiarities, they are comparable with the Aptian-Albian radiolarians of Western Australia (Ellis, 1993). Consequently it can be postulated that sea basins of South India were situated during the Albian-Cenomanian in the temperate latitudes of the Southern Hemisphere.

[MRI-guided breast microbiospy or macrobiopsy: which is the best option for a small tumor?].  

PubMed

The choice of the optimum therapeutic strategy for breast cancer depends on the histological diagnosis of the sample obtained by biopsy. The microbiopsy is the preferred method as it provides an accurate diagnosis of the histological type as well as the main prognostic factors, whilst being simple, fast and inexepensive. However, some infraclinic breast tumors are not accessible by conventional guidance due to excessive depth inside the breast, their small size or technical inability to image them by mammography or ultrasonography. In those cases, the MRI guidance may help to perform the biopsy. Most MRI biopsies are made by large-core needle that are known to alter the histological structure of the tumor and to disturb the anatomopatholgical analysis (size and surgical margin). Those are very important elements to know before treatment. Our case report details an original technique of MRI microbiopsy of a deep 4mm opacity found on the occasion of a patient's mammography. The operative specimen revealed an invasive ductal carcinoma of 4mm diameter which scored III on the Elston and Ellis scale (oestrogen and progesterone receptors tested negative and HER-2 was over-expressed). It was associated with a high grade in situ ductal carcinoma. No systemic treatment was prescribed due to the small size of the carcinoma. The development of partially or totally amagnetic microbiopsy pistols would help perform microbiopses guided by MRI. PMID:24852912

2013 environmental health legislation.  

PubMed

The NEHA Government Affairs program has a long and productive association with the National Conference of State Legislatures (NCSL). The organizations have worked together on any number of legislative and policy areas that directly impact the environmental health profession. One of the keys to the successes of the NEHA/NCSL collaboration has been the recognition of the fact that often some of the most significant legislation and policy initiatives related to environmental public health occur in state legislatures. The states have, in a very real sense, been the innovators in developing new programs and practices. In recognition of this fact, we have asked NCSL to provide occasional overviews of state environmental public health legislative activity, covering topics that are of the most pressing public concern. Doug Farquhar, program director for NCSI's Environmental Health Program, has worked with NCSL since 1990. Mr. Farquhar directs development, management, and research for the Environmental Health Program. These projects encompass consultation and policy analysis of state and federal policies and statutes, regulations, and programs regarding environmental and related topics for state legislatures and administrative programs. Amy Ellis is a law clerk for NCSL within the Environment, Energy, and Transportation Group. As a law clerk she has researched a wide variety of environmental health policies. She is expected to obtain her JD from the University of Colorado Law School in 2015. PMID:24288852

Spin dependent Drell-Yan in QCD to O({alpha}{sub s}{sup 2}) (I). (The non-singlet sector)  

SciTech Connect

A study of the order {alpha}{sub s}{sup 2} corrections to the Drell-Yan (non-singlet) cross section for incoming states of arbitrary longitudinal helicities is presented. The study is performed in the case of the transverse momentum distributions, q{sub T}, of the lepton pair and extends the calculation of Ellis Martinelli and Petronzio (EMP) to the polarized case. They use the {ovr MS} scheme and the t'Hooft-Veltman regularization for the helicity projectors. From their results one can obtain the bulk of the totally inclusive NNLO cross section for the production of a Drell-Yan pair in the non-singlet sector by a simple integration over the heavy photon momentum. They show that in the {ovr MS} helicity is not conserved, unless a finite renormalization is done to reenter into a physical ({ovr MS}{sub p}) scheme. This aspect of the calculation follows the same trend as in polarized production of single and double photon to O({alpha}{sub s}{sup 2}). In the unpolarized limit they reproduce all the results of EMP.
