Ellis-van Creveld syndrome.  

PubMed

Ellis-van Creveld (EvC) syndrome or chondroectodermal dysplasia is an autosomal recessive disorder with characteristic clinical manifestations. The four principal characteristics are chondrodysplasia, polydactyly, ectodermal dysplasia and congenital heart defects. Its incidence in the general population is low. The oral manifestations of EvC syndrome include both soft tissues and teeth, but the dental literature on the subject is scarce. The present case describes the constant and variable oral findings in these patients, which can be diagnosed at any age, even during pregnancy. The presence of a variety of oral manifestations, such as fusion of upper lip to the gingival margin, presence of multiple frenula, abnormally shaped and microdontic teeth and congenitally missing teeth requires multidisciplinary dental treatment, with consideration for the high incidence of cardiac defects in these patients.

Ellis-van Creveld syndrome.  

PubMed

Ellis-van Creveld syndrome (EVC) is a chondral and ectodermal dysplasia characterized by short ribs, polydactyly, growth retardation, and ectodermal and heart defects. It is a rare disease with approximately 150 cases reported worldwide. The exact prevalence is unknown, but the syndrome seems more common among the Amish community. Prenatal abnormalities (that may be detected by ultrasound examination) include narrow thorax, shortening of long bones, hexadactyly and cardiac defects. After birth, cardinal features are short stature, short ribs, polydactyly, and dysplastic fingernails and teeth. Heart defects, especially abnormalities of atrial septation, occur in about 60% of cases. Cognitive and motor development is normal. This rare condition is inherited as an autosomal recessive trait with variable expression. Mutations of the EVC1 and EVC2 genes, located in a head to head configuration on chromosome 4p16, have been identified as causative. EVC belongs to the short rib-polydactyly group (SRP) and these SRPs, especially type III (Verma-Naumoff syndrome), are discussed in the prenatal differential diagnosis. Postnatally, the essential differential diagnoses include Jeune dystrophy, McKusick-Kaufman syndrome and Weyers syndrome. The management of EVC is multidisciplinary. Management during the neonatal period is mostly symptomatic, involving treatment of the respiratory distress due to narrow chest and heart failure. Orthopedic follow-up is required to manage the bones deformities. Professional dental care should be considered for management of the oral manifestations. Prognosis is linked to the respiratory difficulties in the first months of life due to thoracic narrowness and possible heart defects. Prognosis of the final body height is difficult to predict.

Ellis-van Creveld syndrome: its history.  

PubMed

The story of Ellis-van Creveld syndrome is one of serendipity. By chance, Simon van Creveld and Richard Ellis purportedly met on a train and combined their independently encountered patients with short stature, dental anomalies and polydactyly into one landmark publication in 1940. They included a patient used in work published previously by Rustin McIntosh without naming McIntosh as a coauthor. This patient was followed radiologically by Caffey for nearly two decades. In 1964, Victor McKusick felt compelled to investigate a brief report in an obscure pharmaceutical journal on an unusual geographic cluster of short-statured Amish patients in Pennsylvania. This review highlights the lives of the individuals involved in the discovery of Ellis-van Creveld syndrome in their historic context. PMID:23754541

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.

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.

Oral manifestations of Ellis-van Creveld syndrome  

PubMed Central

Ellis-van Creveld syndrome is a rare autosomal-recessive disorder characterized by short limbs, post-axial polydactyly, ectodermal dysplasia, edentulous mandibular incisor region, absence of mucobuccal fold, congenitally missing teeth, slight serrations of the alveolar ridge and multiple small alveolar notches. The clinical report not only describes the classical oral and dental manifestations of Ellis-van Creveld syndrome but also presents unusual findings such as single-rooted and funnel-shaped primary first molars, single conical roots of primary second molars and taurodontisum, which must be considered in the differential diagnostic criteria to avoid misdiagnosis of syndromes. The article also discusses the differential diagnosis and preventive and therapeutic oral health care for these patients. The management of Ellis-van Creveld syndrome is multidisciplinary and, therefore, the oral health care provider should get updated with latest knowledge for timely referral to prevent the patient from further complications of heart defect and bony deformity.

Havelock Ellis's literary criticism, canon formation, and the heterosexual Shakespeare.  

PubMed

Famous as the author of an early full-length scientific study of sexual inversion or homosexuality, English sexologist Havelock Ellis was also a literary critic responsible for initiating publication of the famous Mermaid Series of "The Best of Plays of the Old Dramatists" in the late-nineteenth century. Personally editing the first volume of plays by Christopher Marlowe and a later collection by tragedian John Ford, Ellis associated these playwrights here and in his scientific work, Sexual Inversion, with ideas about normative and so-called abnormal sexualities at the start of the twentieth century. Ellis, thus, helped give expression to a literary canon of early English dramatists in which modern, anachronistic ideas about sexual subjectivity play a part. While this article does not claim that Ellis was the necessary source for later criticism, it shows how, over the whole of the twentieth century, Shakespeare's priority in the literary canon came to be posited at least in part on his apparent sexual normality in contrast with a supposedly homosexual Christopher Marlowe and other playwrights such as Ford or Francis Beaumont and John Fletcher associated with varying degrees of sexual difference.

Evolving science in adolescence: comment on Ellis et al. (2012).

Ellis et al. (2012) bring an evolutionary perspective to bear on adolescent risky behavioral development, clinical practice, and public policy. The authors offer important insights that (a) some risky behaviors may be adaptive for the individual and the species by being hard-wired due to fitness benefits and (b) interventions might be more successful if they move with, rather than against, the natural tendencies of an adolescent. Ellis and colleagues criticize the field of developmental psychopathology, but we see the 2 fields as complementary. Their position would be enhanced by integrating it with contemporary perspectives on dynamic cascades through which normative behavior turns into genuinely maladaptive outcomes, dual processes in adolescent neural development, and adolescent decision making. Finally, they rightly note that innovation is needed in interventions and policies toward adolescent problem behavior. PMID:22545848

Inspection and assessment of energy conservation opportunities at Ellis Island National Park, Ellis Island, New York  

SciTech Connect

Ellis Island is a National Park Service (NPS) facility located in New York Harbor that hosts two million visitors per year. The main building houses exhibits and artifacts, food and gift concessions, and staff work and office spaces in a 200,000-square-foot floor area. Heating and cooling of the main building are provided by a central heating and cooling plant, housed in an adjacent 20,000-square-foot building, with distribution by nine main fan systems and perimeter radiators. Energy end-use estimates were obtained by reconciling connected load characteristics with billing data. The energy-use intensities are about 40 kWh/ft{sup 2}-yr for electricity and 170,000 Btu/ft{sup 2}-yr for natural gas. Energy use is higher than expected for facilities of this type in this region. This high energy use is due to a number of factors. A large fraction of the lighting is provided by incandescent lamps. Constant-volume air-handlers and reheat coils are used in most of the exhibit spaces. Tight temperature and humidity control is achieved in these spaces at the expense of substantial energy use for simultaneous heating and cooling. The large window area is made up of entirely of single-glazed units. Ventilation is controlled by time schedules, not occupant load. Most motors and pumps are single-speed rather than the more efficient variable speed drive type. A preliminary assessment of the potential for energy conservation has been made after a site inspection and analysis of utility bills, building plans, and other information. The electric savings potential is over 30% using available, generally cost-effective technologies. The fossil fuel savings potential is over 1,500 MBtu per year and could be much higher because 10,000 MBtu/yr of natural gas consumption could not be accounted for in our analysis. Cost-effective Energy Conservation Opportunities were identified in the areas of lighting, HVAC, central plant, envelope, motors, and other equipment and loads.

Potential flood and debris hazards at Katherine Landing and Telephone Cove, Lake Mead National Recreation Area, Mohave County, Arizona  

USGS Publications Warehouse

Katherine Landing is a recreation site on the east shore of Lake Mohave, an impoundment on the Colorado River southeast of Las Vegas, Nevada. With proper inspection and maintenance, the present (1979) channel and diking system at Katherine Landing is judged adequate to confine and restrain floods up to and including the 100-yr flood. In contrast, the 500-yr flood probably would not be confined by some parts of the diking system. The Telephone Cove area, traversed by North and South Telephone Cove Washes, is hazardous for all floods, especially for the 100-yr and more severe floods. Determinations of peak discharge are based on streamflow regression analyses, and channel capacities are based on field surveys of channel-flow capacities. The extreme flood - a flood meteorologically and hydrologically possible but so rare as to preclude a frequency estimate - could cause great damage and possible loss of life at both the Katherine Landing and the Telephone Cove sites. The present dikes would be topped or breached by extreme flooding. (USGS)

On the mechanism of trap closure of Venus flytrap ( Dionaea muscipula Ellis)

The rapid trap closure of Dionaea muscinula Ellis has been explained by either a loss of turgor pressure of the upper epidermis, which should thus become flexible, or by a sudden acid-induced wall loosening of the motor cells. According to our experiments both explanations are doubtful. Objections against the turgor mechanism come from the determination by extracellular measurements from the

Ellis-van Creveld syndrome (EVC) is an autosomal recessive disorder characterized by disproportionate dwarfism, polydactyly, and congenital heart disease. This rare disorder is found with increased frequency among the Old Order Amish community in Lancaster County, Pennsylvania. We have used linkage analysis to localize the gene responsible for the EVC phenotype in nine interrelated Amish pedigrees and three unrelated families from Mexico, Ecuador, and Brazil. We now report the linkage for the Ellisvan Creveld syndrome gene to markers on the distal short arm of human chromosome 4, with Z{sub max} = 6.91 at {theta} = 0.02 for marker HOX7, in a region proximal to the FGFR3 gene responsible for the achondroplasia phenotype. 17 refs., 2 figs., 1 tab.

Effect of crocetin from Gardenia jasminoides Ellis on sleep: a pilot study.  

PubMed

Crocetin is a pharmacologically active carotenoid compound of Gardenia jasminoides Ellis used as a traditional herbal medicine and natural colorant. The present pilot study investigated the effect of crocetin on sleep. The clinical trial comprised a double-blind, placebo-controlled, crossover trial of 21 healthy adult men with a mild sleep complaint. It included two intervention periods of 2 weeks each, separated by a 2-week washout period. We measured objective sleep quality using an actigraph, and assessed the subjective symptoms using St Mary's Hospital Sleep Questionnaire. Actigraph data showed that after administration of crocetin, the number of wakening episodes was reduced compared to that of the placebo (p=0.025). Subjective data from St Mary's Hospital Sleep Questionnaire showed that crocetin tended to improve the quality of sleep compared to sleep before its intake. Additionally, no side effects from crocetin intake were observed. The results suggest that crocetin may contribute to improving the quality of sleep. PMID:20537515

Ellis-van Creveld syndrome in an Indian child: a case report.  

PubMed

Ellis-van Creveld syndrome is a rare congenital genetic disorder having autosomal recessive inheritance. It is a syndrome affecting the Amish population of Pennsylvania in USA with prevalence rate of 1/5,000 live at birth. In non-Amish population, the birth prevalence is 7/1,000,000. The syndrome is characterized by bilateral postaxial polydactyly of the hands, chondrodysplasia of long bones resulting in acromesomelic dwarfism, ectodermal dysplasia affecting nails as well as teeth and congenital heart malformation. There were very rare reports of this syndrome in dentistry. The present case focuses on the striking and constant oral findings of these patients, which are the main diagnostic features of this syndrome. Since the oral manifestations affect the esthetic, speech, and jaw growth of the child, the dentists have an important role to play in proper management of such case. PMID:22232726

[Prevalence of sarcopenia in geriatric outpatients and nursing homes. The ELLI study.

BACKGROUND: There are few systematic studies on the prevalence of sarcopenia using the new diagnostic criteria in different geriatric care settings. OBJECTIVE: To estimate the prevalence of sarcopenia, using the European Working Group on Sarcopenia in Older People (EWGSOP) criteria in older subjects living in nursing homes and in those who attend geriatric outpatient clinics. MATERIAL AND METHODS: A single country multicentre study in two samples of older subjects: patients cared for in outpatient geriatric clinics, and individuals living in nursing homes. Data collected will include demographic variables, medical history, medication, geriatric syndromes, functional status (assessment of basic and instrumental activities of daily living), mobility, cognitive status, comorbidity, quality of life, nutritional status, and laboratory parameters. For the diagnosis of sarcopenia, 4m walking speed, handgrip strength, and body composition measured by bioelectrical impedance analysis will be assessed. RESULTS: Using the EWGSOP algorithm, the prevalence of sarcopenia in an elderly Spanish population will be estimated. In addition, concordance and correlation between the three parameters included in the definition (muscle mass, muscle strength, and physical performance) will be analysed, using the different existing cut-off points, and examining the diagnostic accuracy of each. Finally, demographic, anthropometric and functional data that define subjects with sarcopenia will be investigated. CONCLUSIONS: The ELLI study should improve knowledge on the prevalence and characteristics of sarcopenia in older people in our population. PMID:23583189

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

Molecular and clinical analysis of Ellis-van Creveld syndrome in the United Arab Emirates  

PubMed Central

Background Ellis-van Creveld (EvC) syndrome is an autosomal recessive chondrodysplastic condition with clinical manifestations that include short-limbs and ribs, postaxial polydactyly and dysplastic nails and teeth. In about two thirds of patients, mutations in either EVC or EVC2 genes have been found to be the underlying cause. Methods In this paper, we describe the molecular (DNA sequencing) and clinical analysis of six children diagnosed with EvC from four different families from the United Arab Emirates (UAE). Results All the children had the common clinical and radiological features of this syndrome. However, DNA sequence analysis of the genes shown to be involved (EVC and EVC2) revealed a novel splice site mutation (c.2047-1G>T) in intron 13 of EVC2 gene in one family. In addition, we confirm previous mutational analyses that showed a truncating mutation in exon 13 of EVC gene (c.1813C>T; p.Q605X) in the second family and a single nucleotide deletion (c.981delG; p.K327fs) in exon 8 of EVC2 gene in the third family. No mutations in the exons, splice sites or the promoter regions of either gene have been found in the index case of the fourth family who exhibited "EvC-like" features. Conclusions Given the small population size of UAE, our data illustrates further the molecular heterogeneity observed in EvC patients and excludes the possibility of a common founder effect for this condition in the UAE reflecting the current ethnic diversity of the country.

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.

Mixed sediment deposition in a retro-arc foreland basin: Lower Ellis Group (M. Jurassic), Wyoming and Montana, U.S.A.  

NASA Astrophysics Data System (ADS)

The “lower” Ellis Group (M. Jurassic) of northern Wyoming and southern Montana affords an excellent opportunity to examine the influence of tectonics, sea-level change, and incipient topography on facies dynamics and the evolution of mixed sediment ramp deposits. The Sawtooth, Piper, and Gypsum Spring formations (Bajocian to Callovian) represent sedimentation along the forebulge of a retro-arc foreland basin. The “lower” Ellis Group records deposition during two transgressive regressive cycles, (1) a Bajocian-age cycle dominated by evaporites and red shales, and (2) a Bathonian-age cycle characterized by carbonates, evaporites, and red shales. These cycles are capped by a Callovian-age cycle distinguished by carbonates and red shales that is represented by the “lower” Sundance and Rierdon Formations. Transgressive episodes favored intensified chemical sediment production resulting in thick units deposited in subtidal to peritidal environments. Regressive periods are characterized by supratidal redbed progradation and subsequent shallowing upward cycles. The depositional cycles in the lower Ellis Group developed due the interplay between sea-level change and tectonic subsidence related to the evolution of a retro-arc foreland basin. Differential subsidence before, during, and after deposition created paleohighs that locally influenced accommodation space and, thereby, complicated depositional and erosional patterns. This paper provides a regional framework for further analysis of the depositional history of the lower Ellis Group by addressing the stratigraphic relationships between the Sawtooth, Piper, and Gypsum Spring Formations.

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.

Effects of Light and Sucrose Levels on the Anatomy, Ultrastructure, and Photosynthesis of Gardenia jasminoides Ellis Leaflets Cultured in vitro.  

PubMed

This article reports the effect of growing conditions on the anatomical and ultrastructural changes associated with the development of photoautotrophy in Gardenia jasminoides Ellis plantlets during shoot multiplication in vitro. Two photosynthetic photon flux densities (PPFD) (50 and 100 µmol m-2 s-1 PPFD: L50 and L100, respectively) and two sucrose concentrations in the culture medium (5 and 30 g L-1: S5 and S30, respectively) were assayed. An increase in PPFD stimulated the development of photosynthetic tissues and led to higher photosynthesis and dark respiration regardless of the sucrose level assayed. However, the effect of sucrose in the medium depended on the PPFD. For the high-PPFD treatment, a low sucrose concentration in the medium stimulated the development of photosynthetic tissues, whereas the opposite effect of sucrose was observed at low PPFD. This study demonstrated that an increase in light intensity to moderate values such as L100 has a beneficial effect on the development of structural changes associated with photoautotrophy. Such an effect is stimulated by low sucrose (S5) levels in the medium. These modifications of usual growing conditions (such as L50 combined with S30) for micropropagation may prove to be useful in mass propagation of gardenia. However, the use of a low sucrose level in addition to conventional growing PPFD may be counterproductive. PMID:10777452

Fructus Gardenia (Gardenia jasminoides J. Ellis) phytochemistry, pharmacology of cardiovascular, and safety with the perspective of new drugs development.  

PubMed

The phytochemistry, cardiovascular pharmacology, toxicology, side effect, and further development prospects of Gardenia jasminoides J. Ellis (GJE) and its main constituents crocins and iridoid glycosides were studied. Numerous studies have confirmed that crocins and iridoid glycosides had effects of antioxidation, anti-inflammatory, anti-atherosclerosis, anti-ischemic brain injuries, anti-platelet aggregation, anti-hyperglycemia, anti-hyperlipidemia, anti-hypertension, and so on. Some of them might be related to several attractive pharmacodynamic actions of GJE such as promoting endothelium growth, protecting neurons, and inducing their differentiation. Both of them make it possible for GJE to prevent and cure thromboembolism and cardiovascular diseases well. From our own basic pharmacological research of GJE extract on several rat models, it has been known that GJE extract markedly prolonged bleeding time and inhibited platelet aggregation and thrombosis. It has significant proliferation effect on both endothelial cells and endothelial progenitor cells as well. As the mechanisms of GJE on those diseases were discussed and summarized, questions about its genetoxicity and hepatotoxicity were also discussed during its safety study to make the foundation for long-term medication and clinical research in the near future.

Extending the spectrum of Ellis van Creveld syndrome: a large family with a mild mutation in the EVC gene  

PubMed Central

Background Ellis-van Creveld (EvC) syndrome is characterized by short limbs, short ribs, postaxial polydactyly, dysplastic nails and teeth and is inherited in an autosomal recessive pattern. We report a family with complex septal cardiac defects, rhizomelic limb shortening, and polydactyly, without the typical lip, dental, and nail abnormalities of EvC. The phenotype was inherited in an autosomal recessive pattern, with one instance of pseudodominant inheritance. Methods Because of the phenotypic overlap with EvC, microsatellite markers were used to test for linkage to the EVC/EVC2 locus. The results did not exclude linkage, so samples were sequenced for mutations. Results We identified a c.1868T>C mutation in EVC, which predicts p.L623P, and was homozygous in affected individuals. Conclusion We conclude that this EVC mutation is hypomorphic and that such mutations can cause a phenotype of cardiac and limb defects that is less severe than typical EvC. EVC mutation analysis should be considered in patients with cardiac and limb malformations, even if they do not manifest typical EvC syndrome.

Refinement of the Wagner-Ellis formula for the minimum radius and the Givargizov-Chernov formula for the growth rate of nanowire  

NASA Astrophysics Data System (ADS)

The Wagner-Ellis formula for the minimum radius of nanowire and empirical Givargizov-Chernov formula for its growth rate according to the vapor-liquid-solid mechanism are refined. The consideration used as a basis is a self-consistent model of stationary growth, at which the adsorption-desorption flow of material into a drop is equal to the drain due to the two-dimensional nucleation. The parameters entering the expression of Givargizov-Chernov type are interpreted, and its range of applicability is determined. The results obtained make it possible to interpret more exactly experimental data, determine the minimum nanowire radius under specified growth conditions, and estimate important energy and kinetic constants.

Antioxidant properties of crocin from Gardenia jasminoides Ellis and study of the reactions of crocin with linoleic acid and crocin with oxygen.  

PubMed

Crocin-a water soluble carotenoid-is found in the fruits of gardenia (Gardenia jasminoides Ellis) and in the stigmas of saffron (Crocus sativus Linne). For crocin purification, gardenia fruits are extracted with 50% acetone, followed by ether washing, ion exchange, and separation by preparative HPLC. Purified crocin with purity of >99.6% has an antioxidative activity at concentrations up to 40 ppm. At 20 ppm the antioxidative activity of crocin is comparable to that of BHA. The antioxidant property of crocin as evaluated by the thiocyanate method was better than with the thiobarbituric acid method. The adduct between the linoleic acid radical and crocin was detected by LC-MS. When crocin reacted with oxygen in the presence of FeSO(4), intermediates such as monohydroperoxides and dihydroperoxides of crocin were formed and detected by LC-MS. PMID:10820042

Voltammetry of 6,6'-dithiodinicotinic acid on a self-assembled phospholipid monolayer prive  

NASA Astrophysics Data System (ADS)

This paper reports a voltammetric study of 6,6'-dithiodinicotinic acid (CPDS) across a biomimetic membrane system consisting of a monolayer of dioleoylphosphatidylcholine, deposited on mercury. Because of the low solubility of this compound and its potential decomposition in alkaline media, estimation of pK values for the carboxyl and amino groups of the pyridine ring of the CPDS entailed using the Hammett equation. UV spectra seem to confirm the presence of the dianionic form of CPDS above pH=3-4. Differential capacity and cyclic voltammetry measurements were made in order to characterize the voltammetric behavior directly on mercury and through a monolayer of dioleoylphosphatidylcholine. Estimation of the CPDS hydrophobicity degree from the partition coefficient in octanol/ water suggests no penetration of the dianion into the monolayer and supports the fact that the named dianion undergoes protonation at the phospholipid/solution interface to give a neutral specie which penetration into the phospholipid region, favored by its higher hydrophobicity, is followed by electrochemical reduction at the mercury surface. Nous avons étudié par voltampérométrie le comportement de l'acide 6,6'-dithiodinicotinique (CPDS) sur l'électrode de mercure couverte par une monocouche de dioleoyl-phosphatidylcholine. La caractérisation électrochimique a été effectuée par des mesures de la capacité différentielle et par voltamétrie cyclique au dessus d'un pH 3-4. Le spectre UV paraît confirmer la présence de la forme dianionique du CPDS. Cependant les données expérimentales associées à une estimation de l'hydrophobicité de la forme dianionique suggèrent que seule la forme neutre du CPDS peut être réduite sur la surface de l'électrode.

Charge induced closing of Dionaea muscipula Ellis trap.  

PubMed

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

Ichnology and paleosubstrates of Austin Chalk (Cretaceous) outcrops: Southern Dallas and Ellis Counties, Texas  

SciTech Connect

Ichnofossils are abundant in outcrops of the Austin Chalk near Waxahachie, Texas (designated site of the Super-Conducting Super Collider). The abundance and diversity of ichnofossils in Austin strata contrast with the paucity of other macrofossils, except large inoceramids. The lower Austin Chalk (Coniacian) disconformably overlies the Eagle Ford Shale (Turonian). Planolites, Thalassinoides, and Chondrites are conspicuous in the lower Austin. Some lower Austin strata contain well-preserved burrows having menicus fillings. However, most lower Austin ichnofossils are poorly preserved and have compacted. The middle Austin Marl and upper Austin Chalk (Santonain) contain Planolites, Chondrites, Thalassinoides, and Pseudobilobites. Several thin, intensely burrowed, Fe-stained, horizons within the middle Austin represent omission surfaces having postomission Thalassinoides. The upper Austin disconformably underlies the Taylor Marl (Campanian). The Austin-Taylor contact is a Rhizocorallium-infested omission surface overlain by a condensed bed of phosphatic and pyritic bioclasts. Upper Austin occurrences of Rhizocorallium and Pseudobilobites are unique for North American Cretaceous chalks. Based on cross-cutting relationships and differences in morphology, diameter, and burrow-filling sediments, numerous ichnospecies of Thalassinoides are discernable throughout the Austin. Variations in preservation quality exhibited by successive generations of ichnofossils record progressive changes in substrate consistency. Earliest formed burrows have diffuse outlines representing an initial thixotropic (softground) Austin substrate. Subsequent generations of burrows have more distinct outlines recording a gradual increase in substrate firmness. Paleo-firmgrounds are common in Austin outcrops; evidence of hardgrounds is lacking. The Thalassinoides-dominated Austin ichnoassemblage represents an inner shelf paleoenvironment.

The secondary metabolites of the saprotrophic wood-decay basidiomycete fungus Granulobasidium vellereum were studied. Six sesquiterpenes were obtained; 2-hydroxycoprinolone (1), 8-deoxy-4a-hydroxytsugicoline (2), 8-deoxydihydrotsugicoline (3), which were previously not described, radulone A and B, and coprinolone ketodiol. Additionally, base-treatment of 1 yielded the diagnostic degradation products 1a and 1b, whereas radulone A was found to form 4 under mild acidic conditions. The structures were determined by NMR, MS, CD and polarimetry, along with biosynthetic considerations. Radulone A fully inhibited the spore germination of the potentially competing fungi Phlebiopsis gigantea, Coniophora puteana and Heterobasidion occidentale at 10?M, 500?M and 100?M, respectively.

Water is arguably our most important natural resource, essential for sustaining life on Earth; necessary to support agriculture and industry; and important for fisheries, power, navigation, and recreation. As world population increases and climate change brings about a redistribution of water and people across our planet, water resource management and conservation are increasingly important. Based on current population projections for Texas, about 85 percent of the state’s projected population will not have enough water by 2060 in drought conditions. Water conservation is critical for meeting the state’s long-term water needs. To that end, the Texas Water Development Board (TWDB) is engaged in a number of education and outreach programs. In this paper, we report on three TWDB educational campaigns. Water Exploration, a Web-based water resources education program for Texas high school students, Put Some Blue in Your Green School, a service learning project designed to promote interaction between schools and their local communities, and Water IQ: Know Your Water, a public awareness campaign for water conservation. Water Exploration uses a pedagogical approach called the Legacy Cycle to involve students in experiential, project-based learning to help them achieve a deeper understanding about water resources. It addresses the need for rigorous curriculum in a vitally important area for the new Texas high school Earth and Space Science Capstone course, as well as Environmental Systems, and Aquatic Science. The interdisciplinary nature of the curriculum encourages students to explore the connections between water resources and economics (water planning, water as a commodity), history (water affects human settlement and migration), and biology (water is essential for life; contaminated water affects living organisms). The ability to integrate information from different disciplines and weigh the perspectives of multiple experts is particularly important for solving the complex problems in the geosciences (e.g. contaminant remediation, flood control, or climate change). Put Some Blue in Your Green School is a service learning program designed to engage students in real-world problem solving. Students form teams to collect and analyze indoor and outdoor water use data, and prepare recommendations for actions to help schools become efficient water users. By forming partnerships with water supply entities and other community members, students learn about the need for good stewardship practices for water resources and engage the community in understanding the need for conservation. Water IQ: Know your water, is a statewide public awareness campaign that educates Texans about water conservation. Through Water IQ, the Texas Water Development Board provides information on water-efficient practices raises the awareness about the importance of water conservation and helps Texans use less water. The program is designed to complement and support existing local and regional conservation efforts. Communities are encouraged to use Water IQ and provide a link from their community web site to the Water IQ web site.

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

The Maurice Ellis lecture for 1986. The responsibility of emergency medicine towards the prevention of road accidents.  

PubMed Central

It is argued that doctors who work in accident and emergency departments should play their part in road accident prevention. It is suggested that this might be done in the field of research, by direct action, through education of the public and by influencing legislation. Examples are given of both small and simple, and major national research projects based in accident and emergency departments. The type of direct action envisaged is modelled on the work of Dr Hayle Hadeson in preventing accidents to children. Examples of the education of the public are drawn from publicity work in the seat-belt campaign, and experiences of lobbying members of parliament in relation to seat-belt legislation are described. The relative under-funding of trauma research compared with cancer of heart disease research is seen as a measure of society's lack of interest in accident prevention, and colleagues unchallenged to do more to alter this situation.

Modeling of ground-water flow in subsurface Austin Chalk and Taylor marl in Ellis County, Texas, near the superconducting super collider site  

SciTech Connect

Numerical models are useful tools for developing an understanding of ground-water flow in sparsely characterized low-permeability aquifers. Finite-difference, cross-sectional models of Cretaceous chalk and marl formations near the Superconducting Super Collider (SSC) were constructed using MODFLOW to evaluate ground-water circulation paths and travel times. Weathered and fractured zones with enhanced permeability were included to assess the effect these features had on flow paths and times. Pump tests, slug tests, packer tests, core tests, and estimates were used to define hydraulic properties for model input. The model was calibrated with water-level data from monitor wells and from wire-line piezometers near a test shaft excavated by the SSC project. A ratio of vertical-to-horizontal permeability of 0.0085 was estimated through model calibration. A chalk-to-marl permeability ratio of 18 was needed to reproduce artesian head in a well completed in chalk beneath marl. Hydraulic head distributions and ground-water flow paths reflected local, intermediate, and regional flow systems with recharge beneath upland surface-water divides and discharge in valleys. Most of the flow (99%) occurred in the weathered zone, with average residence times of 5 to 10 years. Residence time in unweathered chalk bedrock was substantially longer, at an average of 1.7 Ma. As expected, the model demonstrated that deep and rapid ground-water circulation might occur in fracture zones. Particle paths calculated using MODPATH showed that ground-water travel times from recharge areas to the SSC subsurface facilities might be 20 to 60 years where flow is through fracture zones.

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-Al2O3" 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 256m(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-Al2O3 using as the adsorbent for Ni(II) was relatively stable. The kinetic of the Ni(II) adsorption by the bio-Al2O3 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

The paper explores the deterrent effect of punitive damages when capital investment is endogenous to the legal rule. Irrespective of the level of damages, firms can reduce their expected liabilities by either increasing safety (the law’s intended goal) or reducing wealth exposed to liability. We show that punitive damages can exacerbate this wealth reduction effect and thereby reduce deterrence. The

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.

Stable Isotope Fractionation during Cr(III) oxidation by manganese oxides Swati Joshi (sjoshi@calstatela.edu), Wang D T (dtw@mit.edu), Ellis A S (aellis3@calstatela.edu) Johnson T M (tmjohnsn@uius.edu), Bullen T D (tdbullen@usgs.gov)

Cr stable isotope ratios are being used to monitor Cr redox reactions and associated environmental applications. Previous studies have shown that isotope fractionation (expressed as ?53Cr in the remaining reactant Cr(VI) pool) during Cr(VI) reduction ranges from -1.8% to -4.2 % depending on the reducing agent and processes. A few studies have also been put forth for Cr isotope fractionation during oxidation reactions but mechanisms of isotope fractionation during the oxidation process are not well understood. Oxidation of Cr(III) by pyrolusite (?-MnO2) results in Cr(VI) enriched in 53Cr by +1.1%. We present here a summary of the Cr isotope fractionation during the Cr(III) to Cr(VI) oxidation process using different manganese oxides with recent data from oxidation caused by birnessite and manganite. Both birnessite (?-MnO2) and manganite (MnOOH) are considered common secondary forms of manganese oxides. Manganite is often associated with pyrolusite and some studies have also noted the reductive transformation of birnessite to manganite. Experiments with birnessite and manganite are conducted under varying pH (4 to 6), temperature (4oC and 22oC) and concentration of Cr(III) (10 to 50 mg/L) and Mn-oxides (100 to 500 mg/L). During Cr(III) oxidation with birnessite, we observed ?53Cr of the Cr(VI) product ranging from -0.5% to -0.07%. These results differ markedly from those obtained from oxidation with pyrolusite. Here, during oxidation with birnessite, the final Cr(VI) product is depleted in the heavier isotopes, while oxidation with pyrolusite produces Cr(VI) enriched in the heavier isotopes. We attribute these differences to different rates and isotope fractionations associated with the multi-step electron exchange mechanism and to structural differences between the manganese oxides. Cr(III) oxidation on manganite is generally similar to both pyrolusite and birnessite but the different structure and mixed oxidation state of Mn may result in isotope fractionations that are different from the previous form of Mn-oxides examined. The variations in Cr isotope fractionations seen with the different oxidation mechanisms are critical in interpreting Cr stable isotopes where oxidation reactions mobilize Cr.

Abstract Never before have couples been able to control so effectively the number of children they will have. Although involuntary factors still affect family size, continuing advances in contraceptive techniques make deliberate choice an ever more important determinant of fertility. But what factors determine the size of family people will choose ? One type of answer advanced in recent years by Gary Becker views reproductive performance simply as economic behaviour. Couples, he believes, desire fewer children when poor, more when rich. PMID:22077563

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.

Toward an evolutionary forensic psychology.  

PubMed

Most theories of crime have not explored intensively biological and especially evolutionary explanations for criminal behavior. Ellis presents a valuable new perspective that proposes that attention to physiological mechanisms shaped by evolutionary forces can provide insights into the causes of crime and sex differences in the patterns of crime. We discuss other theories and research relevant to Ellis' theory. We also propose that an evolutionary psychological perspective of crime will help to invigorate research and lead to a better understanding of criminality. An integrated evolutionary forensic psychology will help to explain sources of conflict between individuals, situations in which conflict leads to victimization, and victim defenses and coping mechanisms.

A muscle contracting substance from a plant's closing Fly-Trap  

Microsoft Academic Search

A muscle contracting substance (MCS) occurs in crushed, incubated traps of the insectivorous plant, the Venus Fly-Trap (Dionaea muscipula Ellis). This MCS is provisionally identified as lysophosphatidic acid. More MCS is produced from traps which have been touched than from untouched traps, which may be due to activation of phospholipase D. This enzyme hydrolyses phospholipids of membranes, and could alter

Numerous small structures (stellate trichomes) protrude from the surface of marginal hairs, outer leaf surface, and stem of Dionaea muscipula Ellis. None are present inside the trap. Mechanical stimulation causes small action potentials and eventual closure of the trap, independently of the sensitive trigger hairs. Subthreshold stimulation of these structures appears to sensitize the trigger hairs and facilitate closure of

A discussion of "The Transsexual Wish in a Psychotic Character" by Katherine MacVicar, M.D. Patients in increasing numbers are seeking sex-reassignment surgery. The topic receives coverage in both the lay and professional press; many advocate surgery as the only "cure". Clinical study reveals that these patients have borderline personality organization and are seeking to discard bad and aggressive features and to replace them with a new idealized perfection. Surgical procedures in these cases can usefully be conceptualized as a new type of psychosurgery. PMID:738821

Evolving Science in Adolescence  

PubMed Central

Ellis et al. bring an evolutionary perspective to bear on adolescent risky behavioral development, clinical practice, and public policy. They offer important insights that: 1) some risky behaviors may be adaptive for the individual and the species by being hard-wired due to fitness benefits; and 2) interventions might be more successful if they move with, rather than against, the natural tendencies of an adolescent. Ellis et al. criticize the field of developmental psychopathology, but we see the two fields as complementary. Their position would be enhanced by integrating it with contemporary perspectives on dynamic cascades through which normative behavior turns into genuinely maladaptive outcomes, dual processes in adolescent neural development, and adolescent decision-making. Finally, they rightly note that innovation is needed in interventions and policies toward adolescent problem behavior.

Successful sealing of a coronary artery perforation with a mesh-covered stent.  

PubMed

Coronary artery perforation is a rare, but particularly feared and sometimes life-threatening, complication of percutaneous coronary interventions. The incidence of coronary perforation has increased with newer, more invasive interventional devices and techniques like rotablation, excimer laser coronary angioplasty, routine high-pressure balloon dilatation, or chronic total occlusion interventions. Here we describe a case of Ellis grade 2 perforation following a balloon dilatation performed in an in-stent restenotic total occlusion. The perforation was successfully sealed with a recently introduced device, a mesh covered stent (MGuard stent, Inspire MD). This new stent is much more flexible than the polytetrafluoroethylene-covered stent, which is often implanted in Ellis 2 or 3 grade perforations. PMID:22477764

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.

Chiral Lagrangian with broken scale: Testing the restoration of symmetries in astrophysics and in the laboratory  

SciTech Connect

We study matter at high density and temperature using a chiral Lagrangian in which the breaking of scale invariance is regulated by the value of a scalar field, called dilaton [E. K. Heide, S. Rudaz, and P. J. Ellis, Nucl. Phys. A571, 713 (1994); G. W. Carter, P. J. Ellis, and S. Rudaz, Nucl. Phys. A603, 367 (1996); G. W. Carter, P. J. Ellis, and S. Rudaz, Nucl. Phys. A618, 317 (1997); G. W. Carter and P. J. Ellis, Nucl. Phys. A628, 325 (1998)]. We provide a phase diagram describing the restoration of chiral and scale symmetries. We show that chiral symmetry is restored at large temperatures, but at low temperatures it remains broken at all densities. We also show that scale invariance is more easily restored at low rather than large baryon densities. The masses of vector-mesons scale with the value of the dilaton and their values initially slightly decrease with the density but then they increase again for densities larger than {approx}3{rho}{sub 0}. The pion mass increases continuously with the density and at {rho}{sub 0} and T=0 its value is {approx}30 MeV larger than in the vacuum. We show that the model is compatible with the bounds stemming from astrophysics, as, e.g., the one associated with the maximum mass of a neutron star. The most striking feature of the model is a very significant softening at large densities, which manifests also as a strong reduction of the adiabatic index. Although the softening has probably no consequence for supernova explosion via the direct mechanism, it could modify the signal in gravitational waves associated with the merging of two neutron stars.

Comment on the Brans Dicke Bianchi Type-Iii Vacuum Solution  

NASA Astrophysics Data System (ADS)

The author wishes to point out that the Brans-Dicke-Bianchi type-III vacuum solution recently given by Tiwari and Singh (1984) is not new. Moreover, the solution given has no correct Einstein limit, contrary to what is claimed by these authors. The Ellis-MacCallum vacuum solution in the Einstein case can be obtained from the Brans-Dicke solution first given by Lorenz-Petzold (1984).

Large Deviations for Two-Time-Scale Diffusions, with Delays  

SciTech Connect

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.

New features of extended wormhole solutions in the scalar field gravity theories  

NASA Astrophysics Data System (ADS)

This paper reports new interesting features characteristic of wormhole solutions in the scalar field gravity theories. To demonstrate these, using a slightly modified form of the Matos Núñez algorithm, we obtain an extended class of asymptotically flat wormhole solutions belonging to the Einstein minimally coupled scalar field theory. Generally, solutions in these theories do not represent traversable wormholes due to the occurrence of curvature singularities. However, the Ellis I solution of the Einstein minimally coupled theory, when Wick rotated, yields an Ellis class III solution representing a singularity-free traversable wormhole. We see that Ellis I and III are not essentially independent solutions. The Wick-rotated seed solutions, extended by the algorithm, contain two new parameters a and ?. The effect of the parameter a on the geodesic motion of test particles reveals some remarkable features. By arguing for Sagnac effect in the extended Wick-rotated solution, we find that the parameter a can indeed be interpreted as a rotation parameter of the wormhole. The analysis reported here has wide applicability, for it can be adopted in other scalar field theories, including string theory.

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.

Nurse awarded $35,000 in HIV exposure suit against surgeon.  

PubMed

Nurse Katherine Kenny was awarded $35,000 in a suit against a surgeon who exposed her to HIV. Dr. Alfred Gervin did a pre-operative examination of an HIV-positive patient without gloves, in spite of Kenny's warning. In response, and allegedly to show her she had nothing to fear, he then wiped his hands on her arms. She testified that his hands were moist, he had examined the patient's anal area, and that she had a rash on her arms at the time. An expert witness said Kenny should have realized that there is no need for a doctor to wear gloves to touch a patient's skin. However, she was awarded $10,000 in compensatory damages and $25,000 in punitive damages. Her attorney hailed it as a victory for nurses who are abused by doctors in operating rooms. PMID:11365342

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

Cecilia Payne-Gaposchkin became acclaimed in her lifetime as the greatest woman astronomer of all time. Her own story of her professional life, work and scientific achievements is augmented by the personal recollections of her daughter, Katherine Haramundanis, as well as a scientific appreciation by Jesse Greenstein, a historical essay by Peggy Kidwell and, in this new edition, an introduction by Virginia Trimble. Payne-Gaposchkin's overwhelming love for astronomy was her personal guiding light, and her attitude and approach have lessons for all. She received many prestigious awards for her outstanding contributions to science and in 1956 became the first woman to be advanced to the rank of Professor at Harvard University, as well as being the first woman departmental chair. This book will interest both astronomers and those studying the advancement of the position and status of women in society.

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.

Audit of therapeutic interventions in inpatient children using two scores: are they evidence-based in developing countries?  

PubMed Central

Background The evidence base of clinical interventions in paediatric hospitals of developing countries has not been formally assessed. We performed this study to determine the proportion of evidence-based therapeutic interventions in a paediatric referral hospital of a developing country Methods The medical records of 167 patients admitted in one-month period were revised. Primary diagnosis and primary therapeutic interventions were determined for each patient. A systematic search was performed to assess the level of evidence for each intervention. Therapeutic interventions were classified using the Ellis score and the Oxford Centre for Evidence Based Medicine Levels of Evidence Results Any dehydration due to diarrhoea (59 cases) and pneumonia (42 cases) were the most frequent diagnoses. Based on Ellis score, level I evidence supported the primary therapeutic intervention in 21%, level II in 73% and level III in 6% cases. Using the Oxford classification 16%, 8%, 1% and 75% therapeutic interventions corresponded to grades A, B, C, and D recommendations, respectively. Overall, according to Ellis score, 94% interventions were evidence based. However, out of the total, 75% interventions were based on expert opinion or basic sciences. Most children with mild to moderate dehydration (52 cases) were inappropriately treated with slow intravenous fluids, and most children with non-complicated community acquired pneumonia (42 cases) received intravenous antibiotics Conclusions Most interventions were inappropriate, despite the availability of effective therapy for several of them. Diarrhoeal dehydration and community acquired pneumonia were the most common diagnoses and were inappropriately managed. Existing effective interventions for dehydration and pneumonia need to be put into practice at referral hospitals of developing countries. For the remaining problems, there is the need to conduct appropriate clinical studies. Caution must be taken when assigning the level of evidence supporting therapeutic interventions, as commonly used classifications may be misleading

Shell sources of stationary axisymmetric gravitational fields  

NASA Astrophysics Data System (ADS)

A number of solutions for material shell sources of stationary axisymmetric gravitational fields are presented. Explicit solutions are found for shells lying on equipotential hypersurfaces (gtt - const) and generating static 'monopole' fields in prolate and oblate spheroidal coordinates (Zipoy-Voorhees fields). Numerical solutions are found for shells lying on hypersurfaces of constant gphi-t/g sub phi-phi and generating Kerr- and Tomimatsu-Sato (delta = 2) fields. The shells have minimum areas allowed by the energy conditions of Hawking and Ellis.

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.

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.

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.

Manifestation of s -> ? fragmentation matrix elements via transverse ? polarization in unpolarized e- e+ annihilation  

NASA Astrophysics Data System (ADS)

Making use of the collinear expansion technique developed by Ellis, Furmanski and Petrozio, and the special propagator concept invented by Qiu, we present a factorization approach to the photon fragmentation tensor for the inclusive Lambda hyperon production. As a result, the structure function F~, which is related to the transverse polarization of the inclusive Lambda hyperon in unpolarized electron-positron annihilation, is expressed as a combination of four parton fragmentation matrix elements. Since the inclusive ? production we considered is theoretically the simplest, our study can be taken as a question to the operatability and practability of the first nonleading QCD factorization theorem in the transverse ? polarization phenomena.

Coronary artery perforation (CAP) after percutaneous coronary intervention is a rare, but serious complication. It can cause cardiac tamponade, acute myocardial infarction or death. The treatments of CAP involve prolonged balloon inflation, emergent surgery, coil embolization, and implantation of covered stent. We have successfully performed the emergent microcoil embolization in a patient with uncontrolled Ellis grade 3 guidewire-induced CAP resulting in delayed cardiac tamponade. Contrasting our usual expectation, the 1-year follow-up angiography showed a patent flow at the embolized site.

Kinematical bounds on jet variables and the heavy jet mass distribution  

NASA Astrophysics Data System (ADS)

We investigate the dependence of the bounds of several QCD jet variables on the order of perturbation theory. We show that the ratio of the heavy jet invariant mass squared to the c.m. energy, MH2/s, is bounded by 1/3 in every order of perturbation theory. To illustrate the consequences, using the recent gluon loop calculations of Ellis et al. we calculate d?/d(MH2/s) to order ?s2 and contrast it with the thrust distribution. It is suggested that the perturbation series for MH2/s converges faster and agrees better with experiment away from the infrared sensitive region.

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.

Prospective memory in adults with traumatic brain injury: an analysis of perceived reasons for remembering and forgetting.  

PubMed

Reasons for prospective remembering and forgetting after traumatic brain injury (TBI) were investigated using Ellis' (1996) five phases of prospective memory as a framework. Participants were 38 individuals with severe TBI and 34 controls. Participants self-rated their perceived reasons for prospective remembering and forgetting using section C of the Comprehensive Assessment of Prospective Memory (CAPM). Significant others also rated participants using the same scale. Analyses were conducted to examine the effect of group membership (TBI or control) on reported reasons for prospective remembering and forgetting. Findings highlighted the TBI group's difficulties with encoding, performance interval, and execution phases of prospective remembering. PMID:17474059

Creep Constitutive Model and Component Lifetime Estimation: The Case of Niobium-Modified 9Cr-1Mo Steel Weldments  

NASA Astrophysics Data System (ADS)

The ?-projection parametric method was used to analyze the creep strain versus time data, obtained in uniaxial tension, from weldments fabricated using a niobium-modified 9Cr-1Mo steel as the weld metal (Ellis, Private communication, 1991, provided the data). We used these data to illustrate a methodology whereby the ?-projection method may be used to obtain estimates of component design creep lifetimes, for specified sets of design stress, temperature, and strains. Furthermore, it is suggested that the creep strain results may be consistent with dislocation climb being the creep deformation mechanism in the alloy.

Can Naturoptics Vision Improvement Methods Help Clear Cataracts, as Claimed by the Member of the Naturopathic Physicians Association of Massachusetts who Stabilized and/ or Improved Vision in all the Retinitis Pigmentosa, RP, Patients Treated by him?  

NASA Astrophysics Data System (ADS)

Mac Dougall was advised against having a single crystalline lens with a slight cataract surgically removed; it would impact her ability to reengage vision's self-correcting feedback mechanisms. Her Florida ophthalmologist removed both lenses. A Massachusetts ophthalmologist was recently de-licensed for improperly performing just those services. An optometrist says reputed vision repair can easily be tracked and evaluated; we posit that Naturoptics effects on cataracts can be similarly assessed. ``Cures'' are detectable. Naturoptics users may show glaucoma reversal. EDWARD R. ELLIS, Jr., N.D. (The Chelmsford Clinic, Massachusetts), stabilizes RP, preventing blindness.

This letter discusses interpolation methods; it is prompted by Akima`s note on local methods of univariate interpolation (April 1996 issue of SIGNUM Newsletter). That note compared various univariate methods, concluding that Algorithm 697 is probably the best. Purpose of this letter is provide information about PCHIC comparable to that given in Akima`s note. The 4 methods (Alg. 514, Alg. 697, PCHIC0, PCHIC1) are applied to the 5 analytic functions in Ellis and McLain`s paper (x{sup 3}, x{sup 4}, exp(-x{sup 2}/2), tanh x, sin x).

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.

Electromagnetic field properties in the vicinity of a massive wormhole  

SciTech Connect

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-Nordstroem 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.

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. The instability is consistent with the earlier numerical analysis in the four-dimensional solution.

Brain tolerance unit: a method to estimate risk of radiation brain injury for various dose schedules  

SciTech Connect

A mathematical formula, has been derived for tolerance of the brain and optic nerves to irradiation. It is expressed in terms of brain tolerance units (btu) where Tissue Dose (rad) - btu x N/sup 0/ /sup 45/ T/sup 0/ /sup 03/. It appears to more realistically reflect brain tolerance than Ellis NSD formula. A dose-tolerance curve has been proposed to analyze relative risk of brain injury for different dose schedules. The btu formula may be able to better evaluate risk-benefit comparisons of different dose schedules in treating various tumors in the brain, sellar region and extracranial sites.

Landau-Levich problem for non-Newtonian liquids.  

PubMed

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

Some performance characteristics of a Prussian blue battery  

NASA Astrophysics Data System (ADS)

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.

Nucleon spin structure functions from HERMES: The first year  

SciTech Connect

HERMES, {und HE}RA {und Me}asurement of {und S}pin, is a second generation exper to study the spin structure of the nucleon by using polarized internal gas targets in the HERA 28 GeV electron storage ring. Scattered positrons and coincident hadrons are detected in an open geometry spectrometer which includes particle identification. Inclusive data with polarized {sup 3}He give the spin structure function {ital g{sup n}{sub 1}(x)} and the Ellis-Jaffe integral RR{Lambda} = {integral}{sub 0}{sup 1} {ital g{sup n}{sub 1}(x)dx} for the neutron. The semi-inclusive spin asymmetries are a unique and sensitive probe of the flavor dependence of quark helicity distributions and properties of the quark sea. Data taken in 1995 with unpolarized hydrogen and deuterium targets provide measurements of the flavor distributions of sea and valence quarks. In a preliminary analysis, {Lambda}{sup {ital n}}{sub 1} = -0.032{+-}0. 013{sub {ital stat.}} {+-} O.017{sub {ital syst.}} is obtained at Q{sup 2} = 3(GeV/c){sup 2} for the Ellis-Jaffe integral.

Prenatal programming of postnatal plasticity?  

PubMed

Evidence indicates that maternal prenatal distress predicts problematic health and behavioral outcomes in children as well as infant/child cortisol levels and negative emotionality as reviewed here. Evidence that these physiological and behavioral characteristics themselves moderate environmental effects on development in a "for better and for worse" manner consistent with Belsky's differential susceptibility hypothesis and Boyce and Ellis' notions of biological sensitivity to context raises the prospect that susceptibility to rearing is a function of nurture (i.e., fetal environment), consistent with Boyce and Ellis' proposal that plasticity can be shaped by developmental experience. This hypothesis is supported by new findings from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development showing that low birth weight, a marker for an adverse prenatal environment, predicts infant difficult temperament, which is a susceptibility factor that we previously showed as moderating, in a for better and for worse manner, the effects of parenting and child care quality on socioemotional functioning. Moreover, recent Gene × Environment interaction research raises the prospect that some fetuses may be more susceptible to such "prenatal programming of postnatal plasticity" as a result of their genetic makeup. If this proves true, it will be consistent with the conclusion that early developmental plasticity is a function of both nature and nurture and may be evolutionarily adaptive, a further possibility considered in the discussion.

Demagnifying gravitational lenses toward hunting a clue of exotic matter and energy  

NASA Astrophysics Data System (ADS)

We examine a gravitational lens model inspired by modified gravity theories and exotic matter and energy. We study an asymptotically flat, static, and spherically symmetric spacetime that is modified in such a way that the spacetime metric depends on the inverse distance to the power of positive n in the weak-field approximation. It is shown analytically and numerically that there is a lower limit on the source angular displacement from the lens object to get demagnification. Demagnifying gravitational lenses could appear, provided the source position ? and the power n satisfy ?>2/(n+1) in the units of the Einstein ring radius under a large-n approximation. Unusually, the total amplification of the lensed images, though they are caused by the gravitational pull, could be less than unity. Therefore, time-symmetric demagnification parts in numerical light curves by gravitational microlensing [F. Abe, Astrophys. J. 725, 787 (2010)] may be evidence of an Ellis wormhole (being an example of traversable wormholes), but they do not always prove it. Such a gravitational demagnification of the light might be used for hunting a clue of exotic matter and energy that are described by an equation of state more general than the Ellis wormhole case. Numerical calculations for the n=3 and 10 cases show maximally ˜10 and ˜60 percent depletion of the light, when the source position is ?˜1.1 and ?˜0.7, respectively.

Coalescence in relativistic atomic wavefunctions  

NASA Astrophysics Data System (ADS)

We investigate the pair distribution functions (PDF)( D. Ellis and R. Matulioniene, APS DAMOP, Storrs, June 2000) and electron coalescence probabilities (ECP) associated with atomic wavefunctions produced by the relativistic multi-configuration (MCDHF) program GRASP92.( F.A. Parpia, C. Froese Fischer and I.P. Grant, CPC 94,) 249 (1996) We compare with corresponding PDF results obtained( David G. Ellis, Phys. Rev. A 53,) 3986 (1996) from non-relativistic MHCF( C. Froese Fischer, CPC 64,) 369 (1991) wavefunctions. It is known that MCDHF results for certain transition amplitudes do not agree with MCHF results in the non-relativistic limit.( Kim, Parente, Marques, Indelicato and Desclaux, PRA 58,) 1885 (1998) We find a similar effect in that the PDF predicted by GRASP92 may not reduce to that predicted by MCHF. Also we study the effect of increasing the number of configurations used in the MCDHF solution. This generally reduces the ECP as well as the energy, but this is not uniformly true. These effects are illustrated by means of ECP calculations and PDF plots associated with states in helium, nitrogen, silicon, and members of the neon isoelectronic sequence.

Should I stay or should I go? Some thoughts on the variants of intimate violence.  

PubMed

Approaches to understanding and potentially intervening in the variations of the risk of lethal and sublethal violence against women are suggested. Batterers vary in their ability to desist techniques of control, patterns of dangerousness, and lethality. Such variations are important to explore because of the extent it offers in maximizing the options for women seeking respite, escape and refuge from such violence. The indisputable evidence that some men abuse and batter when they court women warns of the links between heterosexual intimacy and men's abuse. Alvi and Selvee proved that the seriousness of such abuse and violence rises as the relationship advances from casual to serious dating to cohabitation. Termination of the relationship does not guarantee women's safety; separation, rather than divorce per se, is the critical risk factor in lethal violence. Although some women who leave violent men may acutely feel the threat of lethal violence, its actuality is not predictable, an area being explored by Ellis and DeKeseredy. Knowledge about men's lethality to intimate partners is crucial for improving the services and advocacy for women battered by men. When analyzing mechanisms to support women challenging domestic violence and aid in the reduction of separation femicide Ellis and DeKeseredy propose the enhancement of interventions that increase the confidence of the woman and symbolize our opposition to her abuse. Finally, provision of legal advocacy, facilitative divorce legislation, and assistance for battered women lying on the understanding of all public service personnel who work with intimate violence.

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

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.

Charged lepton flavour violation and (g-2)? in the Littlest Higgs model with T-Parity: a clear distinction from Supersymmetry  

NASA Astrophysics Data System (ADS)

We calculate the rates for the charged lepton flavour violating decays elli ? ellj?, ? ? ell?, ? ? ell?, ? ? ell?', ?- ? e-e+e-, the six three body leptonic decays ?- ? elli-ellj+ellk- and the rate for ?-e conversion in nuclei in the Littlest Higgs model with T-parity (LHT). We also calculate the rates for KL,S ? ?e, KL,S ? ?0?e and Bd,s ? elliellj. We find that the relative effects of mirror leptons in these transitions are by many orders of magnitude larger than analogous mirror quark effects in rare K and B decays analyzed recently. In particular, in order to suppress the ? ? e? and ?- ? e-e+e- decay rates and the ?-e conversion rate below the experimental upper bounds, the relevant mixing matrix in the mirror lepton sector VHell must be rather hierarchical, unless the spectrum of mirror leptons is quasi-degenerate. We find that the pattern of the LFV branching ratios in the LHT model differs significantly from the one encountered in the MSSM, allowing in a transparent manner to distinguish these two models with the help of LFV processes. We also calculate (g-2)? and find the new contributions to a? below 1 ? 10-10 and consequently negligible. We compare our results with those present in the literature.

p53 domains: structure, oligomerization, and transformation.  

PubMed Central

Wild-type p53 forms tetramers and multiples of tetramers. Friedman et al. (P. N. Friedman, X. B. Chen, J. Bargonetti, and C. Prives, Proc. Natl. Acad. Sci. USA 90:3319-3323, 1993) have reported that human p53 behaves as a larger molecule during gel filtration than it does during sucrose gradient sedimentation. These differences argue that wild-type p53 has a nonglobular shape. To identify structural and oligomerization domains in p53, we have investigated the physical properties of purified segments of p53. The central, specific DNA-binding domain within murine amino acids 80 to 320 and human amino acids 83 to 323 behaves predominantly as monomers during analysis by sedimentation, gel filtration, and gel electrophoresis. This consistent behavior argues that the central region of p53 is globular in shape. Under appropriate conditions, however, this segment can form transient oligomers without apparent preference for a single oligomeric structure. This region does not enhance transformation by other oncogenes. The biological implications of transient oligomerization by this central segment, therefore, remain to be demonstrated. Like wild-type p53, the C terminus, consisting of murine amino acids 280 to 390 and human amino acids 283 to 393, behaves anomalously during gel filtration and apparently has a nonglobular shape. Within this region, murine amino acids 315 to 350 and human amino acids 323 to 355 are sufficient for assembly of stable tetramers. The finding that murine amino acids 315 to 360 enhance transformation by other oncogenes strongly supports the role of p53 tetramerization in oncogenesis. Amino acids 330 to 390 of murine p53 and amino acids 340 to 393 of human p53, which have been implicated by Sturzbecher et al. in tetramerization (H.-W. Sturzbecher, R. Brain, C. Addison, K. Rudge, M. Remm, M. Grimaldi, E. Keenan, and J. R. Jenkins, Oncogene 7:1513-1523, 1992), do not form stable tetramers under our conditions. Our findings indicate that p53 has at least two autonomous oligomerization domains: a strong tetramerization domain in its C-terminal region and a weaker oligomerization domain in the central DNA binding region of p53. Together, these domains account for the formation of tetramers and multiples of tetramers by wild-type p53. The tetramerization domain is the major determinant of the dominant negative phenotype leading to transformation by mutant p53s. Images

The potentiation of two components of the reach-to-grasp action during object categorisation in visual memory.

Fadiga, L., & Rizzolatti, G. (2002). Hand action preparation influences the responses to hand pictures. Neuropsychologia, 40, 492-502]. The present study investigates compatibility effects for two elements of reach-to-grasp action during the visual mental imagery of objects-the compatibility of an object for grasping with a power and precision grasp, and the orientation of an object (left/right) for grasping by a particular hand (left/right). Experiment 1 provides further evidence for compatibility effects of a 'seen' object for grasping with a power and precision grasp. The experiment shows that compatibility effects are obtainable when an object is presented in an array of four objects and not just on its own. Experiment 2 provides evidence that compatibility effects of an object for grasping with a power and precision grasp can also be observed when participants make an action response to an object 700 ms after it has been removed from view. Experiment 3 investigates compatibility effects for the orientation of an object for grasping by a particular hand during visual mental imagery, but finds no evidence for such effects. The findings are discussed in relation to two arguments put forward to reconcile ecological and representational theories of visual object recognition. PMID:16376844

Class-first analysis in a continuum: an approach to the complexities of schools, society, and insurgent science  

NASA Astrophysics Data System (ADS)

This essay addresses Katherine Richardson Bruna's paper: Mexican Immigrant Transnational Social Capital and Class Transformation: Examining the Role of Peer Mediation in Insurgent Science, through five main points . First, I offer a comparison between the traditional analysis of classism in Latin America and Richardson Bruna's call for a class-first analysis in the North American social sciences where there has been a tendency to obviate the specific examination of class relations and class issues. Secondly, I discuss that a class-first analysis solely cannot suffice to depict the complex dimensions in the relations of schools and society. Thus, I suggest a continuum in the class-first analysis. Third, I argue that social constructions surrounding issues of language, ethnicity, and gender necessarily intersect with issues of class and that, in fact, those other constructions offer compatible epistemologies that aid in representing the complexity of social and institutional practices in the capitalist society. Richardson Bruna's analysis of Augusto's interactions with his teacher and peers in the science class provides a fourth point of discussion in this essay. As a final point in my response I discuss Richardson Bruna's idea of making accessible class-first analysis knowledge to educators and especially to science teachers.

Verification Study of Buoyancy-Driven Turbulent Nuclear Combustion  

ScienceCinema

Buoyancy-driven turbulent nuclear combustion determines the rate of nuclear burning during the deflagration phase (i.e., the ordinary nuclear flame phase) of Type Ia supernovae, and hence the amount of nuclear energy released during this phase. It therefore determines the amount the white dwarf str expands prior to initiation of a detonation wave, and so the amount of radioactive nickel and thus the peak luminosity of the explosion. However, this key physical process is not fully understood. To better understand this process, the Flash Center has conducted an extensive series of large-scale 3D simulations of buoyancy-driven turbulent nuclear combustion for three different physical situations. This movie shows the results for some of these simulations.

New Directions for Nuclear Data  

NASA Astrophysics Data System (ADS)

The evaluation of nuclear data has gone on for over 75 years. After WWII it was realized that the rate of accumulation of nuclear data had become too rapid for individual scientists and engineers to scan the literature so the modern nuclear data program was funded in the US by an act of Congress under the leadership of Katherine Way. In the 1970's at Oak Ridge National Laboratory the Nuclear Data Sheets ENSDF file format was designed and continues to be used, largely unchanged, today. Although originally envisioned to support nuclear applications, ENSDF today now largely supports basic nuclear structure research. As data evaluation became a specialization a gulf developed between the research, application, and data communities that has widened over time. At this juncture in history we are facing the joint dilemmas of disconnects between research and data activities, an aging nuclear data workforce, and pressures from funding agencies to work more efficiently. In this talk I will discuss recent developments and opportunities in nuclear data and the challenges ahead of us to modernize the nuclear data program and better integrate it into the nuclear physics research community.

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.

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.

Prospective constraints on neutrino masses from a core-collapse supernova  

NASA Astrophysics Data System (ADS)

We discuss the prospects for improved upper limits on neutrino masses that may be provided by a core-collapse supernova explosion in our Galaxy, if it exhibits time variations in the neutrino emissions on the scale of a few milliseconds as suggested by recent two-dimensional simulations. Analyzing simulations of such neutrino emissions using the wavelet technique adopted in [J. Ellis, H.-T. Janka, N. E. Mavromatos, A. S. Sakharov, and E. K. G. Sarkisyan, Phys. Rev. DPRVDAQ1550-7998 85, 045032 (2012)10.1103/PhysRevD.85.045032], we find that an upper limit m?˜0.14eV could be established at the 95% confidence level if the time variations in emissions were to be preserved during neutrino propagation to the Earth.

When motor attention improves selective attention: the dissociating role of saliency.  

PubMed

There is evidence that preparing and maintaining a motor plan ("motor attention") can bias visual selective attention. For example, a motor attended grasp biases visual attention to select appropriately graspable object features (Symes, Tucker, Ellis, Vainio, & Ottoboni, 2008). According to the biased competition model of selective attention, the relative weightings of stimulus-driven and goal-directed factors determine selection. The current study investigated how the goal-directed bias of motor attention might operate when the stimulus-driven salience of the target was varied. Using a change detection task, two almost identical photographed scenes of simplistic graspable objects were presented flickering back and forth. The target object changed visually, and this change was either high or low salience. Target salience determined whether or not the motor attended grasp significantly biased visual selective attention. Specifically, motor attention only had a reliable influence on target detection times when the visual salience of the target was low. PMID:19921595

Reduced autonomic responses to faces in Capgras delusion.  

PubMed Central

People experiencing the Capgras delusion claim that others, usually those quite close emotionally, have been replaced by near-identical impostors. Ellis & Young suggested in 1990 that the Capgras delusion results from damage to a neurological system involved in orienting responses to seen faces based on their personal significance. This hypothesis predicts that people suffering the Capgras delusion will be hyporesponsive to familiar faces. We tested this prediction in five people with Capgras delusion. Comparison data were obtained from five middle-aged members of the general public, and a psychiatric control group of five patients taking similar anti-psychotic medication. Capgras delusion patients did not reveal autonomic discrimination between familiar and unfamiliar faces, but orienting responses to auditory tones were normal in magnitude and rate of initial habituation, showing that the hyporesponsiveness is circumscribed.

Splinting the rheumatoid hand.  

PubMed

Splinting of the rheumatoid hand is a complex topic. Understanding is assisted by the use of precise terminology and so is accurate prescription. Dynamic and static orthoses can be prescribed for any part of the upper limb to assist function or provide resistance exercise. Orthoses can be valuable in planning surgery and assisting return of function postoperatively. The importance of training in prescription, manufacture, fitting and wearing of orthoses is stressed and careful discussion with the patient is vital. Thermoplastic materials have provided a new spectrum of designs. Spring wire attachments developed at Chessington (Wynn Parry et al, 1970), Odstock (Glanville, 1962) and The London Hospital (Ellis, 1981) have introduced further possibilities. Designs should be functional and must be acceptable to the patient. PMID:6398183

Childhood experience and the development of reproductive strategies.  

PubMed

Even though a great deal of mainstream developmental psychology is devoted to understanding whether and how experiences in childhood shape psychological and behavioral development later in life, little theoretical attention has been paid to why such cross-time influences should characterize human development. This is especially true with respect to the well-studied determinants of mating, pair bonding and parenting. Theoretically, Draper and Harpending (1982), Belsky, Steinberg and Draper (1991), Ellis (2004) and Chisholm (1996) have all addressed this lacuna, stimulating research on linkages between childhood experience and reproductive strategy which is summarised herein. Concern for experiential effects on pubertal timing distinguishes this line of inquiry from more traditional developmental studies because an evolutionary perspective suggests that experiences in the family might affect somatic development. Twenty years since BSD advanced their prediction, it seems clear that female pubertal timing is related to select aspects of early family experience. PMID:20100424

A brief chronicle of cytology: from Janssen to Papanicolaou and beyond.  

PubMed

The aim of our study was to outline and present the major hallmarks in the history of clinical cytology. For this purpose, an extensive research in modern literature and the PubMed database was undertaken. Furthermore, we studied original papers and books of the pioneers in cytopathology. The development of the first microscope by Hans and Sacharias Janssen is a hallmark in biological sciences, since the study of microcosmos was made feasible. From the discovery of single cells by Robert Hooke and the cell theory by Schleiden and Schwann till the establishment of exfoliative cytology by George Papanicolaou and the invention of fine-needle aspiration biopsy technique by Martin and Ellis, there is a three-century continuum of important discoveries and research. Today, flow cytometry and the introduction of molecular techniques have revolutionized medicine and are expected to change the face of cytology in the near future. PMID:22807413

Site holds promise for ecosystem and biogeochemical investigations  

NASA Astrophysics Data System (ADS)

Ellis Fjord, located in the Vestfold Hills of East Antarctica (68.5°S, 78°E), exhibits a range of environments, from essentially marine at its sea-ward end, to permanently stratified basins with hypersaline brines at its inland end. The drainage basin of the fjord contains small areas of mosses and lichens, but no higher plants, and supplies fresh water to the fjord in ephemeral summer melt streams. Direct anthropogenic inputs are negligible or non-existent, as are those from other mammals and birds. The fjord exhibits unusual biological and chemical properties, and offers the opportunity to study oceanic processes in isolation and at small scales. It also has the logistical advantage of proximity to the facilities of Australia's year-round Davis research station.

Laws, causation and dynamics at different levels  

PubMed Central

I have two main aims. The first is general, and more philosophical (§2). The second is specific, and more closely related to physics (§§3 and 4). The first aim is to state my general views about laws and causation at different ‘levels’. The main task is to understand how the higher levels sustain notions of law and causation that ‘ride free’ of reductions to the lower level or levels. I endeavour to relate my views to those of other symposiasts. The second aim is to give a framework for describing dynamics at different levels, emphasizing how the various levels' dynamics can mesh or fail to mesh. This framework is essentially that of elementary dynamical systems theory. The main idea will be, for simplicity, to work with just two levels, dubbed ‘micro’ and ‘macro’, which are related by coarse-graining. I use this framework to describe, in part, the first four of Ellis' five types of top-down causation.

No genome barriers to promiscuous DNA  

NASA Astrophysics Data System (ADS)

Farrelly and Butow (1983) used the term 'promiscuous DNA' in their report of the apparent natural transfer of yeast mitochondrial DNA sequences into the nuclear genome. Ellis (1982) applied the same term in an editorial comment. It is pointed out since that time the subject of DNA's promiscuity has exploded with a series of reports. According to a report by Stern (1984), movement of DNA sequences between chloroplasts and mitochondria is not just a rare event but is a rampant process. It was recently concluded that 'the widespread presence of ctDNA sequences in plant mtDNA is best regarded as a dramatic demonstration of the dynamo nature of interactions between the chloroplast and the mitochondrion, similar to the ongoing process of interorganellar DNA transfer already documented between mitochondrion and nucleus and between chloroplast and nucleus'.

Measurement of the spin dependent structure function of the nucleon at SMC  

NASA Astrophysics Data System (ADS)

This dissertation presents the complete and final results for the spin dependent structure functions for the proton and the deuteron from the Spin Muon Collaboration (SMC) experiment at CERN. The experiment used polarized high energy muon scattering from polarized proton and deuteron targets, in order to measure the muon-proton and muon- deuteron cross section asymmetries. From these measurements one obtains the virtual photon absorption cross section asymmetries for the proton and the deuteron. Using results from unpolarized scattering experiments the spin dependent structure functions for the proton and deuteron are achieved. In order to compare our results with theoretical predictions, which are the Bjorken sum rule and the Ellis-Jaffe sum rule, a QCD evolution procedure is used. The results of the comparison of our results with these sum rules is presented.

Patients' access to personal health information.  

PubMed

Four physicians comment on an issue paper from the Department of Health and Social Security about provisions of the Data Protection Act that would permit patient access to computerized health records in 1987 unless the Secretary of State rules otherwise. S. Jenkins, a general practitioner, fears that patient access would refocus the record on the doctor's best interests rather than the patient's. C.J. Dickinson, a medical professor, welcomes access as fostering trust. M.A. Heasman, a health administrator, opposes unrestricted access but urges physicians to reveal more to patients. B.W. Ellis, a consultant surgeon, holds that patients have a right to see their records, subject to physician discretion in disclosing information to the patient's general practitioner or other third party. An interprofessional working group's "Statement on subject access to personal health information" rejects unrestricted access lest it inhibit health professionals from recording sensitive data.

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.

As users of head-tracked head-mounted display systems move their heads, latency causes unnatural scene motion. We 1) analyzed scene motion due to latency and head motion, 2) developed a mathematical model relating latency, head motion, scene motion, and perception thresholds, 3) developed procedures to determine perceptual thresholds of scene-velocity and latency without the need for a head-mounted display or a low-latency system, and 4), for six subjects under a specific set of conditions, we measured scene-velocity and latency thresholds, and compared the relationship between these thresholds. Resulting PSEs and JNDs of latency thresholds are in the same range of Ellis and Adelstein. The results are a step toward enabling scientists and engineers to determine latency requirements before building immersive virtual environments using head-mounted display systems. PMID:21593997

Recurrent short rib polydactyly syndrome.  

PubMed

We present three consecutive cases of skeletal dysplasias of a non-consanguineous couple with five pregnancies. The diagnosis of short-rib polydactyly syndrome (SRPS) was feasible by ultrasound during the 1st trimester of pregnancy. SRPS represents a heterogeneous group of lethal skeletal dysplasias. It is characterised by short limb dwarfism complicated by thoracic hypoplasia, polydactyly and different anomalies of major organs such as congenital heart defects and renal dysplasia. Four major types of the SRPS have been described: type I (Saldino-Noonan); type II (Majewski); type III (Verma-Naumoff) and type IV (Beemar-Langer). However, there is phenotypic overlapping between four types and with those of non-lethal skeletal dysplasias (i.e. Ellis-van Creveld syndrome and Jeune syndrome). Our cases show the importance of the nuchal translucency (NT) scan that offers the opportunity to examine fetal anatomy in the 1st trimester and diagnose rare skeletal abnormalities early in pregnancy.

Large Deviation Theorems Revisited: Information-Spectrum Approach  

NASA Astrophysics Data System (ADS)

In this paper we show some new look at large deviation theorems from the viewpoint of the information-spectrum (IS) methods, which has been first exploited in information theory, and also demonstrate a new basic formula for the large deviation rate function in general, which is expressed as a pair of the lower and upper IS rate functions. In particular, we are interested in establishing the general large deviation rate functions that are derivable as the Fenchel-Legendre transform of the cumulant generating function. The final goal is to show, under some mild condition, a necessary and sufficient condition for the IS rate function to be derivable as the Fenchel-Legendre transform of the cumulant generating function, i. e., to be a rate function of Gärtner-Ellis type.

Ruelle-Lanford Functions and Large Deviations for Asymptotically Decoupled Quantum Systems  

NASA Astrophysics Data System (ADS)

We recover, expand, and unify quantum (and classical) large deviation results for lattice Gibbs states. The main new ingredient in this paper is a control on the overlap of spectral projections for non-commutative observables. Our proof of large deviations is based on Ruelle-Lanford functions [20, 34] which establishes the existence of a rate function directly by subadditivity arguments, as done in the classical case in [23, 32], instead of relying on Gärtner-Ellis theorem, and cluster expansion or transfer operators as done in the quantum case in [21, 13, 27, 22, 16, 28]. We assume that the Gibbs states are asymptotically decoupled [23, 32], which controls the dependence of observables localized at different spatial locations. In the companion paper [29], we discuss the characterization of rate functions in terms of relative entropies.

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

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.

The groove move: action affordances produce fluency and positive affect.  

PubMed

In two experiments we show that the experience of processing fluency can be grounded in the motor system. We manipulated whether responses in a stimulus-response paradigm were congruent or incongruent with the orientation of graspable objects. Besides the typical affordance effect (Tucker & Ellis, 1998), namely a reaction time advantage for responses made with the hand for which it would be easier to grasp the object, our results reveal that such a visuo-motor congruence elicits positive affect when preceded by incongruent trials (Experiment 1). Experiment 2 demonstrates that individuals are aware of this fluency experience and can consciously report on it. Moreover, by manipulating the task contingencies, we show that the affordance effect itself can be modulated by the experience of processing fluency. Our results are in line with theories assuming a direct coupling between perception and action (Hommel, Müsseler, Aschersleben, & Prinz, 2001; Prinz, 1997; Smith & Semin, 2004). PMID:21768065

Aerospora of an Eragrostis curvula pasture in South Africa.  

PubMed

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

Nucleon matrix elements of higher-twist operators from the instanton vacuum  

NASA Astrophysics Data System (ADS)

We compute the nucleon matrix elements of QCD operators of twist 3 and 4 in the instanton vacuum. We consider the operators determining 1/Q2-power corrections to the Bjorken, Ellis-Jaffe and Gross-Llewellyn-Smith sum rules. The nucleon is described as a soliton of the effective chiral theory derived from instantons in the 1Nc expansion. QCD operators involving the gluon field are systematically represented by effective operators in the effective chiral theory. We find that twist-3 matrix elements are suppressed relative to twist 4 by a power of the packing fraction of the instanton medium. Numerical results for the spin-dependent (d(2), f(2)) and spin-independent twist-3 and -4 matrix elements are compared with results of other approaches and with experimental estimates of power corrections. The methods developed can be used to evaluate a wide range of matrix elements relevant to DIS.

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

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.

Proposed additions to the SHADOW ray-tracing code for general-asymmetric perfect-crystal optics  

SciTech Connect

The dynamical theory of the diffraction of X-rays from perfect crystals is traditionally expressed in terms of Maxwell`s equations using a semi-classical theory originally due to Ewald and von Laue. Combining the work of Batterman and Cole, Caticha and Caticha-Ellis, and Zachariasen, a formalism is obtained that treats the general asymmetric, thick and thin crystal, Laue and Bragg cases within the second order dispersion surface approximation. The authors have implemented this formalism with thick Bragg crystal E-field boundary value conditions in several routines they have added to one of the Advanced Photon Source (APS) versions of the SHADOW ray-tracing code in order to provide the ability to ray trace inclined double-crystal monochromators and high-resolution backscattering analyzers. These additions have been submitted to the University of Wisconsin Center for X-Ray Lithography for consideration for inclusion in the next version of SHADOW.

Calculations of bottom quark production at hadron colliders  

SciTech Connect

This thesis studies Monte Carlo simulations of QCD heavy flavor production processes (p{bar p} {yields} Q({anti Q})X) at hadron colliders. ISAJET bottom quark cross-sections are compared to the O({alpha} {sub s}{sup 3}) perturbative calculation of Nason, Dawson, and Ellis. These Monte Carlo cross-sections are computed from data samples which use different parton distribution functions and physics parameters. Distributions are presented in the heavy quark's transverse momentum and rapidity. Correlations in rapidity and azimuthal angle are computed for the heavy flavor pair. Theory issues which arise are the behavior of the cross-section at low and high values of transverse momentum and the treatment of double counting problems in the flavor excitation samples. An important result is that ISAJET overestimates bottom quark production cross-sections and K factors. These findings are relevant for estimates of rates and backgrounds of heavy floor events.

We Detect Blue Light Phenomena Correlating with Environmental and Weather Changes, and Historic Native Americans or Their Place Names.  

NASA Astrophysics Data System (ADS)

Katahdin (Christ Cathar Spirit-signal stronghold) in Maine is sacred to the Penobscot Indian Nation. That mountain complex, and areas like Ellis Pond, ME and Penley Hill/Anasagunticook (adherent of Jesus Christ Spirit-signal doctor church) of the Mexico/Rumford/Mountain Valley region, also in Maine, have an association with historic Native Americans like the medicine woman Molocket/Molly Ockett. We have observed that these and other regions generate electromagnetic field (EMF) signals, which we can detect visually and in other ways. Such signals have sometimes been associated with significant and dynamic weather phenomena. Ohio's Serpent Mound and associated regions, or those now occupied by the Hopi Indian Nation, formerly an ancient Anasazi site, or areas of the current and earlier Mayan Nations, or the Nazca Plateau of Peru, may generate signals correlating with climate change, that may impact our technology, as in major power blackouts.

Remembering the past and imagining the future: a role for nonvisual imagery in the everyday cognition of blind and sighted people.  

PubMed

Images can be generated in all sensory modalities. Nevertheless, research on the everyday use of mental imagery, for example in autobiographical memory tasks, has suggested that it is only visual images that facilitate memory retrieval (e.g., Williams, Healy, & Ellis, 1999). If this is the case, individuals born without sight may be forced to rely more on verbal encoding (Goddard & Pring, 2001). This paper explores the presence and everyday role of nonvisual sensory imagery in 16 individuals with and 16 without sight. Using a cue word paradigm, contrary to previous research, Experiment 1 suggested that for both blind and sighted people, nonvisual imageries have a significant role to play in the generation of autobiographical memories. These results were reinforced by similar findings in Experiment 2, which used the same cue word method to explore the role of visual and nonvisual (auditory) imagery when generating future events. The results refute the claim that "useful" imagery in everyday tasks is exclusively visual. PMID:17077028

American RadioWorks: An Imperfect Revolution  

NSDL National Science Digital Library

For those who experienced federally-mandated school desegregation in the 1970s and 1980s, it was something many of them will never forget. American RadioWorks recently took on this very compelling era in American history by sending Kate Ellis and Catherine Winter to Louisville and Charlotte to talk with people about their experiences with school desegregation. They returned with many hours of recordings, and visitors can take in the substantial fruits of their labors on this site. Visitors can listen to the complete radio program here, read a transcript, and also offer their own recollections with this process as well. For those who might be pressed for time, they can also click on photographs of interviewees to take in their individual memories of this period. Educators might find that this program could be used in the classroom as an additional multimedia activity to start discussion about a wide range of topics.

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.

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.

The development of Japanese passive syntax as indexed by structural priming in comprehension.  

PubMed

A number of previous studies reported a phenomenon of syntactic priming with young children as evidence for cognitive representations required for processing syntactic structures. However, it remains unclear how syntactic priming reflects children's grammatical competence. The current study investigated structural priming of the Japanese passive structure with 5- and 6-year-old children in a visual-world setting. Our results showed a priming effect as anticipatory eye movements to an upcoming referent in these children but the effect was significantly stronger in magnitude in 6-year-olds than in 5-year-olds. Consistently, the responses to comprehension questions revealed that 6-year-olds produced a greater number of correct answers and more answers using the passive structure than 5-year-olds. We also tested adult participants who showed even stronger priming than the children. The results together revealed that language users with the greater linguistic competence with the passives exhibited stronger priming, demonstrating a tight relationship between the effect of priming and the development of grammatical competence. Furthermore, we found that the magnitude of the priming effect decreased over time. We interpret these results in the light of an error-based learning account. Our results also provided evidence for prehead as well as head-independent priming.

Transforming a conservative company--one laugh at a time.  

PubMed

You wouldn't think of Brady Corporation as an obvious place in which to find a fun culture. This traditional Midwestern company, a manufacturer of industrial signs and other identification products, didn't even allow employees to have coffee at their desks until 1989. But when Katherine Hudson became CEO in 1994, she and her executive team determined that injecting some fun into the company's serious culture could create positive effects within the organization and contribute to increased performance and sales. In this article, Hudson distills her approach to overhauling Brady's culture into six principles of serious fun: More people than you might think are comfortable having fun at work; used with an awareness of cultural sensitivities, fun and laughter really are well-understood international languages; humor can help companies get through tough times; fun can be embodied in formal programs; spontaneous efforts at humor can also be effective; and encouraging fun should begin at the top. She richly illustrates each principle with examples. At Brady, getting people to loosen up and enjoy themselves has fostered a company esprit de corps and greater team camaraderie. It has started conversations that have sparked innovation, helped to memorably convey corporate messages to employees, and increased productivity by reducing stress, among other benefits. And the company has doubled its sales and almost tripled its net income and market capitalization over the past seven years. Brady's experience suggests that promoting fun within the workplace can lead not only to a robust corporate culture but also to improved business performance. PMID:11447616

Potential impact of differential production of the Cry2Ab and Cry1Ac proteins in transgenic cotton in response to cold stress.  

PubMed

Transgenic Bollgard II cotton, Gossypium hirsutum L., expresses Cry1Ac and Cry2Ab proteins that provide control of lepidopteran larvae, including Helicoverpa and Heliothis species (Lepidoptera: Noctuidae) worldwide. Experiments conducted at Katherine, Northern Territory, Australia evaluated the impact of night minimum temperatures on Cry1Ac and Cry2Ab protein levels in Bollgard II cotton. In both 2003 and 2004, potted plants were either grown outside continuously or protected from cold in a glasshouse each night. In 2003, bulked samples of leaves were taken after two periods of low minimum temperature and used to determine a cold-stress threshold and critical period. In 2004, replicated samples were taken on 10 dates spanning five periods of low minimum temperature, allowing analysis of seasonal variation in Cry protein levels. The protein level was markedly higher for Cry2Ab than for Cry1Ac. Cry1Ac protein level peaked midseason and was not adversely affected by minimum temperatures down to 2.6 degrees C. The Cry2Ab protein level remained approximately constant but was reduced by low minimum temperatures (threshold, approximately 14 degrees C) for up to 6 d after each chill. The rate of Cry2Ab protein loss was 1.15 and 1.01% per chilling day-degree below threshold in 2003 and 2004, respectively. Impact would seem to be negligible on both the overall efficacy against lepidopteran larvae in-crop and on the current pyramided genes/high-dose/refuge Bt resistance-management strategies because the cold-stress effect is transient, a high level of Cry2Ab protein is still expressed, and there is no impact of chilling on Cry1Ac protein level.

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.

[90th anniversary of founding the first children's hospital in Serbia].  

PubMed

The first children's hospital in Serbia, as an exclusive paediatric intitution, was founded in a deserted military barrack in Studenieka Street, near the Military Hospital, in January 1919. The founder was Dr. Katherine MacPhail, a young Scottish lady doctor, who came to Serbia for the first time in January 1915, with the first "Scottish Women's Hospital". After that, she worked as a volunteer during the First World War in France and on the Thessalonica Front. In the spring of 1919, the hospital was given an open pavilion in Topcider, which worked only during the summer months till 1924. In November 1919, the hospital was moved to a new building in Knez Milos Street, and then named The Anglo-Serbian Children's Hospital. In February 1920, a new annex, called "Villa Bravaci?", was opened in Dubrovnik, which was active till 1922. In this hospital, the first Training School for Serbian Nurses was opened in 1921, and in February of that year, the hospital moved into its new permanent house in Visegradska Street, where it had 70 beds, three wards with a modern operating theatre, outpatients' department, X-ray outfit and a pharmacy. Because of much better working conditions, the Children's Surgical Department of the General State Hospital headed by Dr. Dimitrije Jovci?, later a professor of the Faculty of Medicine in Belgrade, was accommodated in this hospital from 1923 to 1931. Apart from him, in this hospital, there used to work a number of young Serbian physicians and several of them later became professors of the Belgrade Faculty of Medicine. The hospital worked till 1934, when it was closed, the building was sold and from that money Dr. MacPhail built a new Anglo-Yugoslav Children's Hospital for Tuberculosis of Bones and Joints in Sremska Kamenica.

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.

Characterising the Terrestrial Stable Cr Isotope Cycle  

NASA Astrophysics Data System (ADS)

Cr isotopes were shown to present a sensitive tracer of redox changes in aqueous solutions [1,2]. Here, the potential of stable Cr isotope fractionation in the environment was further investigated by high-precision double- spike MC-ICP-MS measurements. Reduction experiments of Cr(VI) to Cr(III) in aqueous solutions on ion exchange columns confirmed the mass-dependent Cr isotope fractionation of -3.4‰ per atomic mass unit reported by Ellis et al. [1]. Furthermore, these experiments revealed that the fractionation associated with adsorption is minor. This is shown by a very small preferential adsorption of isotopically heavy chromium of most likely Cr(III) species on the anion resin. A similar observation was made for Cr(III) species on cation resin. This is in line with the negligible fractionation effects that have been reported for adsorption of Cr(VI) onto ?-Al2O3 and goethite surfaces [2], respectively. Thus, the large Cr isotope fractionation that accompanies Cr reduction and the small sorption effects of both Cr(VI) and Cr(III) species make stable Cr isotopes a sensitive tracer to detect and quantify redox changes in a variety of geochemical reservoirs. The stable Cr isotope compositions of the principle silicic igneous reservoirs of the Earth do not show measurable variations. ?^{53}Cr/^{52}Cr values (relative to SRM3112a) of six mantle lherzolites (- 0.014±0.083‰; 2 SD), six ultramafic cumulate rocks (-0.034±0.094‰) and five continental and oceanic basalts that represent partial mantle melts (-0.044±0.089‰) are indistinguishable within uncertainties. Thus, unlike as was suggested for Fe isotopes [3], partial mantle melting appears not to fractionate Cr isotopes. Cr(III)-bearing uvarovite and fuchsite minerals from amphibolite facies metamorphic rocks are also equal to those of igneous rock reservoirs. These observations are not unexpected, because there is no apparent redox change of Cr involved during partial mantle melting or metamorphism. Also the fractionation effects caused by potential ligand changes of Cr between solids, and solids and melt are too small to be detected at high-temperatures. Large Cr isotope fractionations with ?^{53}Cr/^{52}Cr values of +0.672 to +1.093‰ were observed for crocoite (PbCr(VI)O4), a mineral that forms in oxidising zones of medium- to high- temperature hydrothermal systems. It has yet to be investigated whether Cr isotopes fractionate during the oxidation of Cr(III) to Cr(VI). It is, however, likely, that Cr behaves like its chemical twin Se that only fractionates during reduction [4]. In this case the observed heavy Cr isotope compositions of crocoites are the result of partial Cr(VI) reduction from the hydrothermal fluid, allowing to quantify changes in redox conditions along the hydrothermal pathway.
