Full Text Available In the Jewish tradition, the Tu Bishvat, or “Festivity of the Trees”, at the end of January is the occasion to challenge the harshness of winter, celebrate nature’s vitality and fruitfulness, and to admire the articulate relationship between man and environment. All those aspects, related to the mythical and spiritual concept of the sacredness of the Land of Israel, are rooted in an antique tradition expressed in Deuteronomy: 20, 19 “When thou shalt besiege a city […], thou shalt not destroy the trees”. A similar concept is announced hundreds years later in a mysterious text, called Perek Shira, imbedded as part of the Tu Bishvat synagogue recitation. At the beginning of the 19th century, the famous Hassidic Rebbe, Nachman from Breslav, meditated intensely about the insolvable bonds existing between human being and the plant’s world. In his book Likkutei Moharan he persuades his disciples: “You should know that every plant and plant/ has its own and specific melody”. In the seventies, this Nigun becomes a very popular and beloved song by the talented Israeli chansonnière Naomi Shemer, born in kibbutz Degania, near the Lake of Galilee. The song is sung in public, at the Shabbat table, in religious and secular occasions, embracing biblical memory, spiritual history and a new musical approach.

We investigate the terahertz coherent synchrotron radiation (CSR) potential of the South Hall Ring (SHR) at MIT-Bates Linear Accelerator Center. The SHR is equipped with a unique single cavity, 2.856 GHz RF system. The high RF frequency is advantageous for producing short bunch length and for having higher bunch current threshold to generate stable CSR. Combining with other techniques such as external pulse stacking cavity, femtosecond laser slicing, the potential for generating ultra-stable, high power, broadband terahertz CSR is very attractive. Beam dynamics issues related to short bunch length operation, and may associated with the high frequency RF system, such as multi-bunch instability are concerned. They could affect bunch length, bunch intensity and beam stability. The SHR is ideal for experimental exploration of these problems. Results of initial test of low momentum compaction lattice and bunch length measurements are presented and compared to expectations.

Design and Testing of the MIT-Bates Stern-Gerlach Polarimeter Cavity

CERN Document Server

Cameron, P; Luccio, A U; MacKay, W W

2005-01-01

Historically, beam polarization measurement has been accomplished by scattering experiments, with the attendant complexity of target and detector installation and operation, and smallness and uncertainty of analyzing powers. The purpose of the present effort is to accomplish fast and accurate polarization measurement not as a scattering experiment, but rather as conventional beam instrumentation, with a resonant cavity pickup. This requires that the coupling of the beam magnetic moment to the pickup be enhanced to bring the signal above the noise floor, and that coupling of the beam charge to the pickup be diminished to reduce the dynamic range problem. We discuss details of cavity design that have been implemented to accomplish these ends. Presently, it is planned to install the cavity in the Bates Ring in early May of this year. Beyond polarimetry, successful polarization measurement will verify the underlying principles, and by pickup/kicker reciprocity will open the serious consideration of the possibilit...

The MIT Bates Accelerator Center is delivering highly polarized electron beams to its South Hall Ring for use in Nuclear Physics Experiments. Circulating electron currents in excess of 200 mA with polarization of 70% are scattered from a highly polarized, but very thin atomic beam source deuterium target. At the electron source a compact diode laser creates photoemission of quasi-CW mA pulses of polarized electrons at low duty factors from a strained GaAs photocathode. Refurbished RF transmitters provide power to the 2856 MHz linac, accelerating the beam to 850 MeV in two passes before injection into the South Hall Ring. In the ring a Siberian snake serves to maintain a high degree of longitudinal polarization at the BLAST scattering target. A Compton laser back-scattering polarimeter measures the electron beam polarization with a statistical acuracy of 6% every 15 minutes.

Population biology and feeding habits of the nephropidlobsterMetanephrops thomsoni (Bate) was studied from a field survey sampled with bottom trawls in the East China Sea. The female/male ratio was 1.06:1. Three size-class groups were discriminated for both sexes, which may correspond to one to three year-old cohorts. The average stage fecundity was 471 in each brood. Larger than two-year-size-class females are multi broods during the breeding season. Gut analysis showed that this lobster is a common camivore and mainly consume crustaceans and fishes, regardless of sex and carapace length size.

Full Text Available Certain aspects of the reproductive dynamics of Argentine red shrimp Pleoticus muelleri (Bate, 1888, distributed between 42°-47°S and 62°W, were investigated. Data and samples were collected during 36 INIDEP research cruises and 87 commercial fishing fleet trips between 1994-2010. Mature and inseminated females size structure as well as the frequency distribution of macroscopic maturity stages of adult females were analyzed on space-time bases. The seasonal development of ovarian maturity stages microscopically determinated was also assessed. Statistical treatment of data included multivariate scaling and cluster analysis. The reproductive activity of the shrimps showed latitudinal differences concerning its onset and duration that could be associated with the variability of environmental conditions. We discuss a shoreward movement of spawning females related to the presence of coastal hydrographic processes that would ensure retention and food for survival of early life stages.Se estudian ciertos aspectos de la dinámica reproductiva del langostino Pleoticus muelleri (Bate, 1988 en el área comprendida entre 42°-47°S y 62°W.

The availability of state-of-the-art instruments such as high performance liquid chromatograph, gas chromatograph-mass spectrometer, inductively coupled plasma-atomic emission spectrometer, capillary electrophoresis system, and ion chromatograph obtained through four Instructional Laboratory Improvement and one Course, Curriculum, and Laboratory Improvement grants from the National Science Foundation has led to a profound change in the structure of the analytical and general chemistry courses at Bates College. Students in both sets of courses now undertake ambitious, semester-long, small-group projects. The general chemistry course, which fulfills the prerequisite requirement for all upper-level chemistry courses, focuses on the connection between chemistry and the study of the environment. The projects provide students with an opportunity to conduct a real scientific investigation. The projects emphasize problem solving, team work, and communication, while still fostering the development of important laboratory skills. Cooperative learning is also used extensively in the classroom portion of these courses.

Information on the single previously described species, Mizotrechus novemstriatus Bates 1872 (type locality: Brazil - Amazonas, Tefé), is updated and 17 new species for the genus from Nicaragua, Costa Rica, Panamá, Colombia, Venezuela, and Guyane are described. The species records in the literature and on determined specimens in some collections of Mizotrechus novemstriatus Bates from Central America are not that species; currently, Mizotrechus novemstriatus is known only from its type locality in Amazonian Brazil. For the new species described, their known general distributions are as follows: Mizotrechus batesisp. n. (Guyane), Mizotrechus bellorumsp. n. (Guyane), Mizotrechus bruleisp. n. (Guyane), Mizotrechus belevederesp. n. (Guyane), Mizotrechus costaricensissp. n. (Costa Rica), Mizotrechus dalensisp. n. (Guyane), Mizotrechus edithpiafaesp. n.

(Guyane), and Mizotrechus woldaisp. n. (Panamá). Long-term use of flight intercept traps in Guyane provided so many new species that apparently the use of FITs is the way to collect adults of this taxon, previously known from very few specimens. Many more species of this genus can be expected to be discovered throughout the Neotropics; the present contribution is a preliminary synopsis with identification key and adult images of all known species. Likely numerous species are yet to be discovered throughout tropical climes.

What Risk? (edited by Roger Bate)

1999-07-01

Roger Bate, Ed. Butterworth-Heinemann: Oxford, UK. 329 pp. Cloth (1997): ISBN 0-7506-3810-9. 56.95. Paper (1999): ISBN 0 7506 4228 9. 29.95. A train carrying radioactive waste had begun its trip in New York and was close to its destination in California. As it stopped, the engineer called to a bystander, "Congratulations." "What for?" said the man. "You get to die. We calculated that each person along the route would receive one-millionth of the lethal dose of radioactivity. No one has died yet and you are the millionth person." "But I have received only one-millionth of the lethal dose." "That doesn't matter, it's a question of statistics." (This story is paraphrased from Rockwell's piece in The Scientist, March 16, 1998, p 7.) What Risk? contains 15 chapters (by 19 authors) arranged in five categories: methodology, science, science policy, commentaries, and perception. It deals in different ways, broadly speaking, with the problems raised by this anecdote. It would make a splendid textbook for high-school students or college undergraduates for a course dealing with pitfalls in extrapolation, unexpected variables, the proper use of statistics, political correctness and absolute safety, evaluation of the scientific literature, and the interplay of science and politics. Each article has an extensive reference list. Among the specific risks discussed are asbestos, benzene, environmental (secondhand) tobacco smoke, dioxin, ionizing radiation, and carcinogens. Some general principles emerge. (i) Since all organisms have repair mechanisms against environmental damage, there are thresholds for all damaging agents. Therefore, extrapolation from high dose rates to very low levels does not make sense. (ii) Doses and dose rates should not be confused. (iii) There are very large species differences in response to damaging agents. (iv) Unrecognized variables lurk everywhere. (v) The costs of enforcing demonstrably false standards are huge. Here are some illustrations. Nilsson

Naomi Moran, a student at the Arnewood School, New Milton, Hampshire was the first recipient of the `Achievement in Physics' prize awarded by the South Central Branch of The Institute of Physics. Naomi received an award certificate and cheque for £100 from Dr Ruth Fenn, Chairman of the Branch, at the annual Christmas lecture held at the University of Surrey in December. She is pictured with Dr Fenn and Steve Beith, physics teacher at the Arnewood School.  Photo Figure 1. Naomi Moran receiving her award (photograph courtesy of Peter Milford). The award is intended to celebrate personal achievement in physics at any level at age 16-17 and is not restricted to those who gain the highest academic results. Schools across the county were invited to nominate suitable candidates; Naomi's nomination by the school's deputy head of science impressed the judges because of her ability to grasp the most difficult parts of the subject quickly, in addition to the fact that she took her AS-level science in year 11 when she was only 16. She is currently studying A-level physics, chemistry and mathematics and hopes to continue her studies at university later this year.

Analyzed data carne from the research cruises of the Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP carned out durmg January 2000, 2001, 2005, and 2007; March 2006; and November 2004, 2005, and 2006 in San Jorge Gulf (Argentina. The biological variables considered were the relative abundances of mature and impregnated female shrimp, whereas the environmental variables corresponded to depth, bottom water temperature and salinity, and the difference between surface and bottom water temperature and salinity. Generalized additive models were used as an exploratory tool for the numerical data and the general linear models as a confirmatory tool. The results showed that the distributions and abundances of mature and impregnated females were related to the bottom water temperature and salinity and to depth. The relationship increased along with temperature; with salinity, however, it decreased for mature females and increased for impregnated females. An optimal depth range was evidenced, where the largest concentrations of these individuáis were located.Se presenta el análisis de la relación entre la abundancia relativa de las hembras maduras e impregnadas del langostino Pleoticus muelleri (Bate, 1888 y las variables ambientales, mediante la aplicación de modelos estadísticos.

LOS IMPERATIVOS DE BELLEZA Y EL DISPOSITIVO MÉDICO

Directory of Open Access Journals (Sweden)

Ma. Candelaria Ochoa Avalos

2011-01-01

Full Text Available En este artículo intentamos releer la tesis central del libro de Naomi Wolf The Beauty Myth: How Images of Beauty Are Used Against Women considerando las narraciones de algunas mujeres que entrevistamos en el marco de una investigación en curso. Naomi Wolf argumenta que las "imágenes de belleza inflexibles y crueles" que definen el "mito de la belleza" constituyen una contraofensiva al feminismo y el movimiento de las mujeres. Como argumentos centrales, Naomi Wolf postula, por un lado, la operación de un poder "represivo" que censura y desvaloriza a las mujeres reales recluyéndolas en el dominio de los intereses privados y, por otro lado, la resistencia o el sometimiento como opciones para enfrentar esta "represión sexual". Por nuestra parte, intentamos complejizar estos planteamientos, recurriendo a las tesis de Michel Foucault sobre la biopolítica, y a los desarrollos de Judith Butler sobre los "mecanismos psíquicos del poder", para concluir que la agencia de las mujeres, en el marco de la decisión de una cirugía cosmética, tiene un carácter paradojal, que implica una sujeción al poder y una habilitación de la agencia en virtud de la "complicidad" fundante con los dispositivos del saber-poder.

García, Gabriel L; Ortega-Arenas, Laura; Hernández, Héctor G; García, Agustín A; Nápoles, Jesús R; Cortés, Ramón R

2009-01-01

Third instars of white grubs of six species associated to agave tequilero in Jalisco, México were described from 1,145 specimens collected from soil samples from September 2006 to August 2007, in the municipalities of Ixtlahuacán del Río, Tepatitlán de Morelos and San Juan de Escobedo, Jalisco, México. Diagnostic characters were illustrated and a key was also included. Cyclocephala comata (Bates) was the most abundant species (63.2%), followed by Phyllophaga ravida (Blanchard) (21.9%), Phyllophaga polyphylla (Bates) (9.4%), Phyllophaga misteca (Bates) (4.1%), Strategus aloeus (L.) (1.1%) and Anomala hoepfneri (Bates) (0.3%). Phyllophaga ravida and A. hoepfneri are reported for the first time on the agave plant and the latter is a new record for the State of Jalisco. All Melolonthidae species showed a marked seasonality with lower number of larvae in June 2007 and high number in August 2007, which is associated with the region's rainy season and the agave plant age, respectively.

Telling our stories: heroin-assisted treatment and SNAP activism in the Downtown Eastside of Vancouver.

Boyd, Susan; Murray, Dave; MacPherson, Donald

2017-05-18

This article highlights the experiences of a peer-run group, SALOME/NAOMI Association of Patients (SNAP), that meets weekly in the Downtown Eastside of Vancouver, British Columbia, Canada. SNAP is a unique independent peer- run drug user group that formed in 2011 following Canada's first heroin-assisted treatment trial (HAT), North America Opiate Medication Initiative (NAOMI). SNAP's members are now made up of former research participants who participated in two heroin-assisted trials in Vancouver. This article highlights SNAP members' experiences as research subjects in Canada's second clinical trial conducted in Vancouver, Study to Assess Longer-term Opioid Medication Effectiveness (SALOME), that began recruitment of research participants in 2011. This paper draws on one brainstorming session, three focus groups, and field notes, with the SALOME/NAOMI Association of Patients (SNAP) in late 2013 about their experiences as research subjects in Canada's second clinical trial, SALOME in the DTES of Vancouver, and fieldwork from a 6-year period (March 2011 to February 2017) with SNAP members. SNAP's research draws on research principles developed by drug user groups and critical methodological frameworks on community-based research for social justice. The results illuminate how participating in the SALOME clinical trial impacted the lives of SNAP members. In addition, the findings reveal how SNAP member's advocacy for HAT impacts the group in positive ways. Seven major themes emerged from the analysis of the brainstorming and focus groups: life prior to SALOME, the clinic setting and routine, stability, 6-month transition, support, exiting the trial and ethics, and collective action, including their participation in a constitutional challenge in the Supreme Court of BC to continue receiving HAT once the SALOME trial ended. HAT benefits SNAP members. They argue that permanent HAT programs should be established in Canada because they are an effective harm reduction

Handling a crisis via a combination of human initiative and godly direction: Insights from the Book of Ruth

Directory of Open Access Journals (Sweden)

Robin Gallaher Branch

2012-12-01

Full Text Available The biblical text introduces Ruth, a Moabite woman, at a time of personal crisis. She faces destitution. Life has handed her multiple blows, amongst them widowhood and childlessness. Her single asset? Naomi, a cranky, elderly but endearing mother-in-law. Naomi, an Israelite and also widowed, is now quite determined to go home to Bethlehem. Ruth joins Naomi’s journey, but for Ruth it is a pilgrimage, for it is at this time that she switches allegiance from the gods of Moab to the God of Israel. As an immigrant facing change on every level – a new culture, a new religion, no friends and no job – Ruth nonetheless triumphs. Within only a couple of months, not only does she marry a prominent and prosperous bachelor, Boaz, but also wins the hearts of her mother-in-law’s friends, the women of Bethlehem. This analysis of her successful pilgrimage offers contemporary guidelines for facing dramatic changes. Using literary method, this article examines one of the Bible’s accounts of how a personal crisis is resolved via a combination of God’s providence and human initiative and courage. Die hantering van ’n krisis deur ’n kombinasie van menslike inisiatief en goddelike bestuur: Insigte uit die boek Rut. Die bybelse teks stel die leser voor aan Rut, ’n Moabitiese vrou, tydens ‘n persoonlike krisis in haar lewe. Sy is ’n weduwee, kinderloos en staar dus armoede in die gesig. Haar enigste pluspunt is Naomi, haar bejaarde, ietwat verbitterde dog innemende skoonmoeder. Naomi, ’n Israeliet en ook ’n weduwee, is vasbeslote om na haar huis in Betlehem terug te keer. Rut vergesel haar en dit word vir Rut ’n pelgrimstog na die God van Israel, weg van die afgode van Moab af. As immigrant wat ’n vreemde kultuur en godsdiens, ’n toekoms sonder vriende en werkloosheid moet verwerk, seëvier Rut uiteindelik. Sy trou binne ‘n paar maande met Boas, ’n prominente en welvarende vrygesel en wen ook die harte van haar skoonmoeder se

Often, in these works, place is doubled, with the present-day physical environment as well...

[Survival of Bacillus anthracis spores in various tannery baths].

Science.gov (United States)

Mendrycka, M; Mierzejewski, J

2000-01-01

The influence of tannery baths: liming, deliming, bating, pickling, tanning, retannage on the survival and on the germination dynamism of B. anthracis spores (Sterne strain) was investigated. The periods and the conditions of this influence were established according to technological process of cow hide tannage. Practically after every bath some part of the spores remained vital. The most effective killing of spores occurred after pickling, liming and deliming. Inversely, the most viable spores remained after bating and retannage process. The lack of correlation that was observed between survival and germination of spores after retannage bath can be explained by different mechanism of spores germination inhibition and their killing.

Radiation chemical effects in experiments to study the reaction of glass in an environment of gamma-irradiated air, groundwater, and tuff

International Nuclear Information System (INIS)

Van Konynenburg, R.A.

1986-01-01

The results of experiments performed by John K. Bates et al. on the reaction of nuclear waste glass with a gamma-irradiated 90 0 C aqueous solution were analyzed using theory developed from past research in radiation chemistry. The aqueous solution they used is similar to what would be expected in a water-saturated environment in a nuclear waste repository in tuff. The purpose of our study was to develop an understanding of the radiation-chemical processes that occurred in the Bates et al. experiments so the results could be applied to the design and performance analysis of a proposed repository in unsaturated tuff in Nevada. For the Bates et al. experiments at the highest dose (269 Mrad), which originally contained about 16 ml of ''equilibrated'' water taken from Nevada Test Site Well J-13 and 5.4 ml of air, we predicted that water decomposition to H 2 and O 2 would produce a pressure increase of at least 1.0 MPa at 20 0 C. We also predicted that nitrogen fixation from the air would occur, producing an increase of 1.6 x 10 -4 M in total fixed nitrogen concentration in solution. In addition, an equimolar production of H + would occur, which would be buffered by the HCO 3 - in the water. The fixed nitrogen in solution was predicted to be present as NO 2 - and NO 3 - with the ratio influenced by the presence of materials catalytic to the decomposition of H 2 O 2 . We found reasonable agreement between our predictions and the observations of Bates et al., where comparisons were possible. We apply the results to the proposed Nevada repository to the degree possible, given the different expected conditions

Comment on 'Effects of quantized scalar fields in cosmological spacetimes with big rip singularities'

International Nuclear Information System (INIS)

Haro, Jaume; Amoros, Jaume

2011-01-01

There are two nonequivalent ways to check if quantum effects in the context of semiclassical gravity can moderate or even cancel the final singularity appearing in a universe filled with dark energy: The method followed in [J. D. Bates and P. R. Anderson, Phys. Rev. D 82, 024018 (2010).] is to introduce the classical Friedmann solution in the energy density of the quantum field, and to compare the result with the density of dark energy determined by the Friedmann equation. The method followed in this comment is to solve directly the semiclassical equations. The results obtained by either method are very different, leading to opposed conclusions. The authors of [J. D. Bates and P. R. Anderson, Phys. Rev. D 82, 024018 (2010)] find that for a perfect fluid with state equation p=ωρ and ω<-1 (phantom fluid), considering realistic values of ω leads to a quantum field energy density that remains small compared to the dark energy density until the curvature reaches the Planck scale or higher, at which point the semiclassical approach stops being valid. The conclusion is that quantum effects do not affect significantly the expansion of the universe until the scalar curvature reaches the Planck scale. In this comment we will show by numerical integration of the semiclassical equations that quantum effects modify drastically the expansion of the universe from an early point. We also present an analytic argument explaining why the method of [J. D. Bates and P. R. Anderson, Phys. Rev. D 82, 024018 (2010)] fails to detect this. The units employed are the same as in [J. D. Bates and P. R. Anderson, Phys. Rev. D 82, 024018 (2010)] (c=(ℎ/2π)=G=1).

Full Text Available This study was designed to evaluate the effect of propellant formulation and geometry on the solid propellant grains internal ballistic performance using core, bates, rod and tubular and end-burn geometries. Response Surface Methodology (RSM was used to analyze and optimize the effect of sucrose, potassium nitrate and carbon on the chamber pressure, temperature, thrust and specific impulse of the solid propellant grains through Central Composite Design (CCD of the experiment. An increase in potassium nitrate increased the specific impulse while an increase in sucrose and carbon decreased specific impulse. The coefficient of determination (R2 for models of chamber pressure, temperature, thrust and specific impulse in terms of composition and geometry were 0.9737, 0.9984, 0.9745 and 0.9589, respectively. The optimum specific impulse of 127.89 s, pressure (462201 Pa, temperature (1618.3 K and thrust (834.83 N were obtained using 0.584 kg of sucrose, 1.364 kg of potassium nitrate and 0.052 kg of carbon as well as bate geometry. There was no significant difference between the calculated and experimented ballistic properties at p < 0.05. The bate grain geometry is more efficient for minimizing the oscillatory pressure in the combustion chamber.

ENGLISH ABSTRACT: There has been an emphasis shift from maintenance management towards asset management, where the focus is on reliable and operational equipment and on effective assets at optimum life-cycle costs. A challenge in the manufacturing industry is to develop an asset performance management model that is integrated with business processes and strategies. The authors developed the APM2 model to satisfy that requirement. The model has a generic reference structure and is supported by operational protocols to assist in operations management. It facilitates performance measurement, business integration and continuous improvement, whilst exposing industry to the latest developments in asset performance management.

AFRIKAANSE OPSOMMING: Daar is ‘n klemverskuiwing vanaf onderhoudsbestuur na batebestuur, waar daar gefokus word op betroubare en operasionele toerusting, asook effektiewe bates teen optimum lewensikluskoste. ‘n Uitdaging in die vervaardigingsindustrie is die ontwikkeling van ‘n prestasiemodel vir bates, wat geïntegreer is met besigheidsprosesse en –strategieë. Die outeurs het die APM2 model ontwikkel om in hierdie behoefte te voorsien. Die model het ‘n generiese verwysingsstruktuur, wat ondersteun word deur operasionele instruksies wat operasionele bestuur bevorder. Dit fasiliteer prestasiebestuur, besigheidsintegrasie en voortdurende verbetering, terwyl dit die industrie ook blootstel aan die nuutste ontwikkelinge in prestasiebestuur van bates.

Uranium-free utopia in B.C

International Nuclear Information System (INIS)

1981-01-01

In 1980 the government of British Columbia called off the Bates Commission inquiry into uranium mining and declared a seven-year moratorium on uranium exploration in the province. Since then the commission has issued its final report, which included the recommendation that exploration could proceed safely. The provincial government, however, has refused to lift the ban. In its other recommendations the Bates Commission stated that future energy needs may require the development of all known uranium resources; that advances in miner protection and tailings disposal could soon make uranium mining acceptably safe; and that uranium mining is morally and ethically acceptable. Specific recommendations on research needs that should be met before uranium mining is allowed in British Columbia were made. (LL)

Theoretical clarity is not “Manicheanism”

Hjørland, Birger

2011-01-01

It is argued that in order to establish a new theoretical approach to information science it is necessary to express disagreement with some established views. The “social turn” in information science is not just exemplified in relation to the works of Marcia Bates but in relation to many different...... researchers in the field. Therefore it should not be taken personally, and the debate should focus on the substance. Marcia Bates has contributed considerably to information science. In spite of this some of her theoretical points of departure may be challenged. It is important to seek theoretical clarity...... and this may involve a degree of schematic confrontation that should not be confused with theoretical one-sidedness, “Manicheanism” or lack of respect....

Policy makers ignoring science and scientists ignoring policy: the medical ethical challenges of heroin treatment

Directory of Open Access Journals (Sweden)

Small Dan

2006-05-01

Full Text Available Abstract A decade of research in Switzerland, The Netherlands, Germany, and Spain now constitutes a massive body of work supporting the use of heroin treatment for the most difficult patients addicted to opiates. These trials concur on this method's safety and efficacy and are now serving as a prelude to the institution of heroin treatment in clinical practice throughout Europe. While the different sampling and research protocols for heroin treatment in these studies were important to the academic claims about specific results and conclusions that could be drawn from each study, the overall outcomes were quite clear – and uniformly positive. They all find that the use of prescribed pharmaceutical heroin does exactly what it is intended to do: it reaches a treatment refractory group of addicts by engaging them in a positive healthcare relationship with a physician, it reduces their criminal activity, improves their health status, and increases their social tenure through more stable housing, employment, and contact with family. The Canadian trial (NAOMI, now underway for over a year, but not yet completed, now faces a dilemma about what to do with its patients who have successfully completed 12 months of heroin and must be withdrawn from heroin and transferred to other treatments in accordance with the research protocol approved by Government of Canada, federal granting body and host institutions. The problem is that the principal criterion for acceptance to NAOMI was their history of repeated failure in these very same treatment programs to which they will now be referred. The existence of the results from abroad (some of which were not yet available when NAOMI was designed and initiated now raises a very important question for Canada: is it ethical to continue to prohibit the medical use of heroin treatment that has already been shown to be feasible and effective in numerous medical studies throughout the world? And while this is being worked

Everyday sexism

CERN Document Server

Bates, Laura

2014-01-01

'If Caitlin Moran's How To Be A Womanis the fun-filled manual for female survival in the 21st century, everyday sexism is its more politicised sister' (Independent on Sunday). After experiencing a series of escalating sexist incidents, Laura Bates started theeveryday sexism projectand has gone on to write 'a pioneering analysis of modern day misogyny' (Telegraph). After an astounding response from the wide range of stories that came pouring in from all over the world, the project quickly became one of the biggest social media success stories of the internet. From being harassed and wolf-whistled at on the street, to discrimination in the workplace and serious sexual assault, it is clear that sexism had become normalised. But Bates inspires women to lead a real change and writes this 'extremely powerful book that could, and should, win hearts and minds right across the spectrum' (Financial Times). Often shocking, sometimes amusing and always poignant, everyday sexism is a protest against inequality and a manif...

Substitution with opioid-agonists (e.g., methadone) has shown to be an effective treatment for chronic long-term opioid dependency. Survival sex work, very common among injection drug users, has been associated with poor Opioid Agonist Treatment (OAT) engagement, retention and response. Therefore, this study was undertaken to determine factors associated with engaging in sex work among long-term opioid dependent women receiving OAT. Data from a randomized controlled trial, the North American Opiate Medication Initiative (NAOMI), conducted in Vancouver and Montreal (Canada) between 2005-2008, was analyzed. The NAOMI study compared the effectiveness of oral methadone to injectable diacetylmorphine or injectable hydromorphone, the last two on a double blind basis, over 12 months. A research team, independent of the clinic services, obtained outcome evaluations at baseline and follow-up (3, 6, 9, 12, 18 and 24 months). A total 53.6% of women reported engaging in sex work in at least one of the research visits. At treatment initiation, women who were younger and had fewer years of education were more likely to be engaged in sex work. The multivariate logistic generalized estimating equation regression analysis determined that psychological symptoms, and high illicit heroin and cocaine use correlated with women's involvement in sex work during the study period. After entering OAT, women using injection drugs and engaging in sex work represent a particularly vulnerable group showing poorer psychological health and a higher use of heroin and cocaine compared to women not engaging in sex work. These factors must be taken into consideration in the planning and provision of OAT in order to improve treatment outcomes. NCT00175357.

Leadership Characters in the Book of Ruth: A Narrative Analysis

Directory of Open Access Journals (Sweden)

Yong Lu

2017-06-01

Full Text Available This article delineates a ground work for shaping Christian leadership characters by examining the book of Ruth, a narrative of coop­eration. First, we introduce the general Biblical wisdom, guidance, and religious precepts on leadership characters from the Bible per se. Second, we depict a synopsis and connotation of the Ruth Narrative combined with the historical background of the late Judges time when Naomi, Elimelech, Ruth and Boaz lived and the social and religious background of Moab where the family of Elimelech dwelt in for ten years. Third, based on those background analyses, the main figures’ dialogues, and their actions, we illustrate their positive servant and mentor leadership characters that include a combination of their distinguished traits and cognitive attributes, as well as some weaknesses of Naomi and Elimelech. In a nutshell, Nao­mi’s leadership characters contain loyalty to God (2:19 – 20, discovering value within (3:1 – 4, and patience and endurance (3:18. Ruth’s leadership characters incorporate faithfulness and positive self-esteem (1:16 – 17, pioneer and daring (2:2, deference (2:10, obedience (3:5, and lov­ing-kindness (3:10. Boaz’s leadership characters include respect (2:4, care (2:5, compassion (2:8 – 9, 11, empowerment (2:15 – 16, leaning on and trusting God (2:12, care (2:14; 3:15, protecting the weak (3:10 – 15, responsibility (3:12, moral integrity and justness (3:13, carefulness (3:14, formation (4:1, unselfishness and cleverness (4:3 – 5, and part­nering (4:9 – 10. While we criticize Elimelech’s risk seeking strategy to migrate their family to a pagan country (1:1 – 2 as a spiritual adventure.

Quasi-elastic scattering of electrons from 40Ca at high momentum transfer

International Nuclear Information System (INIS)

Yates, T.C.

1992-01-01

Previous quasi-elastic electron scattering experiments have yielded seemingly inconsistent results when the integrated longitudinal strength is compared to calculations using the relativistic fermi gas model. Measurements made at Saclay on 12 C, 40 Ca, 48 Ca, 56 Fe, and 208 Pb indicated a smaller integrated longitudinal strength than expected on the basis of the relativistic fermi gas model. However, 238 U data taken at Bates showed nearly the full expected longitudinal strength at a momentum transfer of 550 MeV/c. This is one of the outstanding discrepancies in nuclear physics. Earlier experiments were hampered in that high momentum transfer could not be obtained at forward angles where the longtudinal strength is a large fraction of the total strength. The present experiment was designed to take advantage of the higher energy capability (greater than 800 MeV) at Bates recirculated linac in order to obtain momentum transfers greater than 600 MeV/c at a scattering angle of 45.5 degrees. Under these conditions the longitudinal strength is 40-75% of the total quasi-elastic strength

Thirty-nine morphotypes, 11 genus and 4 species (Artemesia longinaris Bate, 1888, Hexapanopeus schmitii Rathbun, 1930, Menippe nodifrons Stimpson, 1859 and Pleoticus muelleri Bate, 1888 were identified, among them only two morphotypes of Stomatopoda larvae, and the remainder Decapoda larvae. Brachyuran zoeae were the most abundant group and they were well represented by Portunidae and Xanthidae zoeae. Lucifer sp. and Caridea zoeae were the most abundant non-brachyuran taxa. Decapod larvae were observed to occur at all sampling sites, however the spatial distribution demonstrated a general tendency to greater abundance and diversity at the southern sites of the Island. Decapoda and Stomatopoda larvae occurred throughout the year, showing that reproduction is continuous, but that larval input in planktonic community was significantly higher during autumn and spring.Este trabalho tem como objetivo a descrição da distribuição temporal e espacial da composição e abundância de larvas de decápodes nas águas rasas ao redor da Reserva Biológica Marinha do Arvoredo.

Hemoglobin profile studies have been carried out in four samples from different districts of Porto Velho (Rondônia State) in the western Amazonian region of Brazil: Candelária, Bate Estaca, Hemeron (at the State Blood Bank), and São Carlos. Samples from 337 unrelated individuals were collected during medical and paramedical team visits by professionals from the Instituto de Pesquisa em Patologia Tropical and the Centro de Pesquisa em Patologias Tropicais (both research institutes in tropical diseases). The aim of this study is to assess the frequency of alleles in the hemoglobin system, mainly alleles HB*A, *S, and *E. The overall phenotype frequencies were HB A,S = 0.025, HB A,E = 0.006, and HB A,A = 0.969. Samples from the blood bank subjects and samples from the homogeneous areas of São Carlos and Candelária plus Bate Estaca have a chi-square of heterogeneity of 6.383 (p = 0.041) and 8.406 (p = 0.015), respectively. The allele frequencies (HB*A = 0.984, HB*S = 0.012, and HB*E = 0.003) do not significantly differ from frequencies found in other Brazilian regions.

Arnold, R.G.; Minehart, R.C.

1987-05-01

The Workshop on Electronuclear Physics with Internal Targets was held at SLAC on January 5-8, 1987. The idea for this workshop grew out of interest among physicists at SLAC and MIT/Bates who have been exploring the possibilities for internal targets in the PEP ring at SLAC and in a proposed stretcher ring at MIT/Bates. The aim of the workshop was to bring together physicists from these groups and from other laboratories and universities to discuss the new physics that could be made accessible with internal targets, and to share information on recent developments in internal target technology, on the impact of internal targets on ring operation, and on the detector requirements. The workshop was sponsored by NPAS, the program of Nuclear Physics at SLAC, and it was attended by more than 100 physicists from the US, Canada, Europe, and Japan. The workshop sessions began with two days of invited talks followed by two days of shorter presentations organized by the chairmen of four Working Groups.

The UMass group has concentrated on using electromagnetic probes, particularly the electron in high-energy scattering experiments at the Stanford Liner Accelerator Center (SLAC). Plans are also being made for high energy work at the Continuous Beam Accelerator Facility (CEBAF). The properties of this accelerator should permit a whole new class of coincidence experiments to be carried out. At SLAC UMass has made major contributions toward the plans for a cluster-jet gas target and detector system at the 16 GeV PEP storage ring. For the future CEBAF accelerator, tests were made of the feasibility of operating wire drift chambers in the vicinity of a continuous electron beam at the University Illinois microtron. At the same time a program of studies of the nuclear structure of more complex nuclei has been continued at the MIT-Bates Linear Accelerator Center and in Amsterdam at the NIKHEF-K laboratory. At the MIT-Bates Accelerator, because of an unforeseen change in beam scheduling as a result of problems with the T 20 experiment, the UMass group was able to complete data acquisition on experiments involving 180 degrees elastic magnetic scattering on 117 Sn and 41 Ca. A considerable effort has been given to preparations for a future experiment at Bates involving the high-resolution threshold electrodisintegration of the deuteron. The use of these chambers should permit a high degree of discrimination against background events in the measurement of the almost neutrino-like small cross sections that are expected. In Amsterdam at the NIKHEF-K facility, single arm (e,e') measurements were made in November of 1987 on 10 B in order to better determine the p 3/2 wave function from the transition from the J pi = 3 + ground state to the O + excited state at 1.74 MeV. In 1988, (e,e'p) coincidence measurements on 10 B were completed. The objective was to obtain information on the p 3/2 wave function by another means

The new regime necessitates greatly improved costing systems, to improve the efficiency of service provision by creating price competition between providers. Ken Bates and Stan Brignall argue that non-price competition also occurs, with providers 'differentiating' on quality of service/product, flexibility or innovation.

This paper describes the finite-difference time-domain calculation of SAR from 20 MHz to 3 GHz in hybrid voxel-mathematical models of the pregnant female. Mathematical models of the developing foetus at 8-, 13-, 26- and 38-week gestation were converted into voxels and combined with the reference adult female model, NAOMI at a resolution of 2 mm. Whole-body averaged SAR in the mother is presented as well as the average over the foetus, over the foetal brain and in 10 g of the foetus. The electric field values required to produce the ICNIRP public exposure restriction of 2 W kg{sup -1} when averaged over 10 g of the foetus were calculated. Comparison suggests that the ICNIRP public reference level is a conservative predictor of local SAR in the foetus.

The calculations of the whole-body SAR in these four phantoms were performed at the HPA, at NICT and at the Nagoya Institute of Technology (NIT). These were for a plane wave with a vertically aligned electric field incident upon the front of the body from 30 MHz to 3 GHz for isolated conditions. As well as investigating the general differences through this frequency range, particular emphasis was placed on the assumptions of how dielectric properties are assigned to tissues (particularly skin and fat) and the consequence of using different algorithms for calculating SAR at the higher frequencies.

In Togiak, harvesting berries is a practice that goes back countless generations. The berries are the key ingredient in akutaq, called eskimo ice cream. In her classes, Howdyshell’s students write identity poems with lines proclaiming “I am from akutaq,” and describing cherished excursions with parents and grandparents. In 2014, residents discovered that there would be no berries that year: the tundra had not frozen for a sufficient length of time for the berries to regenerate. With a dramatic rise in temperatures, Yu’pik people can no longer rely on digging deep into the permafrost to store food in makeshift freezers. And most distressing: as a result of rising seas, during the next few years, Yu’pik people will be forced to relocate large parts of their community.

A polarized hydrogen/deuterium internal gas target has been constructed and operated at the internal target region of the South Hall Ring (SHR) of the MIT-Bates Linear Accelerator Center to carry out measurements of spin-dependent electron scattering at 850MeV. The target used an Atomic Beam Source (ABS) to inject a flux of highly polarized atoms into a thin-walled, coated storage cell. The polarization of the electron beam was determined using a Compton laser backscattering polarimeter. The target polarization was determined using well-known nuclear reactions. The ABS and storage cell were embedded in the Bates Large Acceptance Toroidal Spectrometer (BLAST), which was used to detect scattered particles from the electron-target interactions. The target has been designed to rapidly (∼8h) switch operation from hydrogen to deuterium. Further, this target was the first to be operated inside a magnetic spectrometer in the presence of a magnetic field exceeding 2kG. An ABS intensity 2.5x10 16 at/s and a high polarization (∼70%) inside the storage cell have been achieved. The details of the target design and construction are described here and the performance over an 18 month period is reported

Several studies indicate that females perform more poorly in economic courses than their male counterparts. Other studies reveal that students' personality types affect their performance in economic courses, as well. The present study explores this issue by testing a number of interactions between gender and the Kersey-Bates temperament types in an ordered probit model explaining students' grades in Principles of Macroeconomics. The results confirm that the interaction of gender and temperame...

A review of continent scale hydrological datasets available for Africa

OpenAIRE

Bonsor, H.C.

2010-01-01

As rainfall becomes less reliable with predicted climate change the ability to assess the spatial and seasonal variations in groundwater availability on a large-scale (catchment and continent) is becoming increasingly important (Bates, et al. 2007; MacDonald et al. 2009). The scarcity of observed hydrological data, or difficulty in obtaining such data, within Africa means remotely sensed (RS) datasets must often be used to drive large-scale hydrological models. The different ap...

Nucleon form factors provide fundamental input for nuclear structure and quark models. Current knowledge of neutron form factors, particularly the electric form factor of the neutron, is insufficient to meet these needs. Developments of high-duty-factor accelerators and polarization-transfer techniques permit new experiments that promise results with small sensitivities to nuclear models. We review the current status of the field, our own work at the MIT/Bates linear accelerator, and future experimental efforts

Abstract This synopsis provides an identification key to the genera of Tribe Lachnophorini of the Western and Eastern Hemispheres including five genera previously misplaced in carabid classifications. The genus Asklepia Liebke, 1938 is revised with 23 new species added and four species reassigned from Eucaerus LeConte, 1853 to Asklepia Liebke, 1938. In addition, a new genus is added herein to the Tribe: Peruphorticus gen. n. with its type species P. gulliveri sp. n. from Perú. Five taxa previously assigned to other tribes have adult attributes that make them candidates for classification in the Lachnophorini: Homethes Newman, Aeolodermus Andrewes, Stenocheila Laporte de Castelnau, Diplacanthogaster Liebke, and Selina Motschulsky are now considered to belong to the Lachnophorini as genera incertae sedis. Three higher level groups are proposed to contain the 18 recognized genera: the Lachnophorina, Eucaerina, and incertae sedis. Twenty-three new species of the genus Asklepia are described and four new combinations are presented. They are listed with their type localities as follows: (geminata species group) Asklepia geminata (Bates, 1871), comb. n, Santarém, Rio Tapajós, Brazil; (hilaris species group) Asklepia campbellorum Zamorano & Erwin, sp. n., 20 km SW Manaus, Brazil, Asklepia demiti Erwin & Zamorano, sp. n., circa Rio Demiti, Brazil, Asklepia duofos Zamorano & Erwin, sp. n., 20 km SW Manaus, Brazil, Asklepia hilaris (Bates, 1871), comb. n, São Paulo de Olivença, Brazil, Asklepia grammechrysea Zamorano & Erwin, sp. n., circa Pithecia, Cocha Shinguito, Perú, Asklepia lebioides (Bates, 1871), comb. n, Santarém, Rio Tapajós, Brazil, Asklepia laetitia Zamorano & Erwin, sp. n., Leticia, Colombia, Asklepia matomena Zamorano & Erwin, sp.n., 20 km SW Manaus, Brazil; (pulchripennis species group) Asklepia adisi Erwin & Zamorano, sp. n., Ilha de Marchantaria, Lago Camaleão, Brazil, Asklepia asuncionensis Erwin & Zamorano, sp. n., Asunción, Río Paraguay

Full Text Available Every language in many countries has its own uniqueness to express wish. In Indonesian, the word “ingin” means want to, or wish to. But in Japanese, there are two classes of word, both have meaning of want or wish. They are jodoushi「～たい」and keiyoushi「ほしい」. These two classes of word usually people find when learning Japanese, especially when reading Japanese comics for children. Therefore, in order to be able to differ the use of those two classes of word and the use of their sentences pattern, as well as the analysis, this research uses Doraemon vol.25-35. As for analyzing　all the data, the use of theories from Tomita Takayuki, Seichi Makino and Michio Tsutsui, Naomi Hanaoka McGloin, and also Fumiko Koide will suit them respectively.

A muon site search using calculated internal fields has been performed for V 2 O 3 , where purely dipolar fields allow a site determination free from covalent complications. The obtained sites are a subset of the Rodriguez and Bates sites found in α-Fe 2 O 3 and indicate muon oxygen bond formation. The sites missing at low temperatures are consistent with the vanadium pairing mechanism for the metal-to-insulator (corundum-to-monoclinic) phase transition. (orig.)

During the year February 1, 1978 to January 31, 1979, the major activities under Task A were completion of the analysis of data taken in Experiment number 99, measurement of the cross section for completion of new π - p→π - π + n, apparatus and software for Experiment number 337, measurement of the cross section for π - p→π - π + n at 200 and 229 MeV, taking data for Experiment number 337, continued preparation for Experiment number 309, and double charge exchange in the disintegration of 16 O, 40 Ca and 208 Pb, consideration of a possible collaboration for detection of protons from μ - capture on nuclei and initiation of an association with physicists at Bates on measurements of (e,e'). The completed analysis of Experiment number 99 has left previous conclusions, that the integrated reaction cross section at the lowest energy is twice that interpolated from early measurements, intact. Experiment number 337 was mounted and the preliminary results for the reaction cross section at 229 MeV agree well with Experiment number 99. The more sophisticated instrumentation used in the latest measurements builds confidence in the validity of these results. An experiment on double charge exchange is being prepared and one on μ - capture is being considered. A graduate student from the University of Wyoming has begun thesis research at Bates

To determine whether brain volume is reduced at 1 year of age and whether these volumes are associated with neurodevelopment in biventricular congenital heart disease (CHD) repaired in infancy. Infants with biventricular CHD (n = 48) underwent brain magnetic resonance imaging (MRI) and neurodevelopmental testing with the Bayley Scales of Infant Development-II and the MacArthur-Bates Communicative Development Inventories at 1 year of age. A multitemplate based probabilistic segmentation algorithm was applied to volumetric MRI data. We compared volumes with those of 13 healthy control infants of comparable ages. In the group with CHD, we measured Spearman correlations between neurodevelopmental outcomes and the residuals from linear regression of the volumes on corrected chronological age at MRI and sex. Compared with controls, infants with CHD had reductions of 54 mL in total brain (P = .009), 40 mL in cerebral white matter (P Development-II scores but did correlate positively with MacArthur-Bates Communicative Development Inventory language development. Infants with biventricular CHD show total brain volume reductions at 1 year of age, driven by differences in cerebral white matter. White matter volume correlates with language development, but not broader developmental indices. These findings suggest that abnormalities in white matter development detected months after corrective heart surgery may contribute to language impairment. ClinicalTrials.gov: NCT00006183.

Since the publication of "Sustainable Communities--building for the future", Government attention has focused largely on high-density affordable housing in the four "growth areas": Thames Gateway; Ashford; Milton Keynes--South Midlands, and London--Stansted--Cambridge. In this article, Thomas Yeung and Tony Bates suggest that a greater and more sustainable impact would be achieved if architects, planners, and developers considered the potential for community-based water and waste management and on-site energy generation and distribution right from the start of the project. In particular, they consider that the communal nature of hospitals, universities, and public/community housing provides a great opportunity for on-site renewable CHP and/or distributed heating, which could combine global environmental benefits with improved local amenities. They describe a simple model for prioritising energy management in the built environment, and draw on lessons learnt at ETRCL in Dagenham and BedZED in Surrey to offer a few recommendations for Government and developers. Tony Bates is the business development manager for Scott Wilson in the South East and is responsible for the promotion of sustainable communities through relationships with architects, developers, land owners and local authorities. Thomas Yeung leads the Energy Infrastructure Technologies group in Scott Wilson. This team offers an integrated approach to clean community-based energy generation, energy management, waste and water management, sustainable transport, and sustainable buildings/communities.

Two of the factors in the formula for allocating common consolidated corporate tax base are susceptible to disadvantage some Member States.

Effect of diffuse roof cover with anti-reflection coating for roses; Effect van diffuus kasdek met Anti Reflectie coating bij Roos

Energy Technology Data Exchange (ETDEWEB)

Garcia Victoria, N.; Kempkes, F.

2012-10-15

The rose Red Naomi was cultivated in two greenhouses at Wageningen UR Greenhouse Horticulture in Bleiswijk, Netherlands (August 2010 - September 2011). One greenhouse covered with normal float glass; the other with AR coated diffuse glass (70% haze). This Anti-Reflection coating on both glass sides compensated for the loss in light transmission caused by the diffusing structure in the glass. The diffuse AR glass lead to a 5.2% higher production (>6.1% fresh weight). Sunscreens were necessary in spring and summer to avoid high light levels on the flower buds, as they cause very high bud temperatures leading to quality problems (blue petal edges and burnt leaf tips). The diffuse greenhouse cover allowed a 100 W/m{sup 2} higher screening threshold than the reference glass. This caused a 2.7% higher daily light integral, able to explain part of the extra production obtained. Part of the extra production achieved can not be explained by the measured factors as no differences were found in the amount of light intercepted by the crop or in leaf photosynthesis under both cover types. The light under the diffuse AR cover was nevertheless much smoother, so the crop seemed to suffer less (lower bud temperatures and less burned leaf tips), and this should provide an explanation for the rest of the extra production. The cover properties did not influence disease development (powdery mildew). The obtained extra production makes the tempered, diffuse glass with Anti Reflection coating on both sides economically feasible [Dutch] Tussen augustus 2010 en september 2011 is bij Wageningen UR Glastuinbouw het effect van diffuus glas, met dubbelzijdige AR coating, op de productie en energiegebruik van roos 'Red Naomi' onderzocht. Onder het diffuse glas werden 5,2% meer bloemtakken geproduceerd, deze rozen waren ook iets langer en zwaarder (6,1% meer versgewicht). Dit verschil kan deels verklaard worden doordat er onder het diffuse glas pas bij hogere stralingsniveau

Client satisfaction among participants in a randomized trial comparing oral methadone and injectable diacetylmorphine for long-term opioid-dependency

Full Text Available Abstract Background Substitution with opioid-agonists (e.g., methadone has shown to be an effective treatment for chronic long-term opioid dependency. Patient satisfaction with treatment has been associated with improved addiction treatment outcomes. However, there is a paucity of studies evaluating patients' satisfaction with Opioid Substitution Treatment (OST. In the present study, participants' satisfaction with OST was evaluated at 3 and 12 months. We sought to test the relationship between satisfaction and patients' characteristics, the treatment modality received and treatment outcomes. Methods Data from a randomized controlled trial, the North American Opiate Medication Initiative (NAOMI, conducted in Vancouver and Montreal (Canada between 2005-2008, was analyzed. The NAOMI study compared the effectiveness of oral methadone vs. injectable diacetylmorphine over 12 months. A small sub-group of patients received injectable hydromorphone on a double blind basis with diacetylmorphine. The Client Satisfaction Questionnaire (CSQ-8 was used to measure satisfaction with treatment. CSQ-8 scores, as well as retention and response to treatment, did not differ between those receiving hydromorphone and diacetylmorphine at 3 or 12 months assessments; therefore, these two groups were analyzed together as the 'injectable' treatment group. Results A total of 232 (92% and 237 (94% participants completed the CSQ-8 at 3 and 12 months, respectively. Participants in both groups were highly satisfied with treatment. Independent of treatment group, participants satisfied with treatment at 3 months were more likely to be retained at 12 months. Multivariate analysis indicated that satisfaction was greater among those randomized to the injection group after controlling for treatment effectiveness. Participants who were retained, responded to treatment, and had fewer psychological symptoms were more satisfied with treatment. Finally, open-ended comments were made by

  Kritisk eftertanke er et væsentligt træk ved den refleksive forbruger - ofte parret med en vis negativitet overfor et brand, en reklame eller forbrugerisme i al almindelighed. Den refleksive forbrugertype kommer til udtryk hos for eksempel en anti-branding guru som Naomi Klein og hendes...... bestseller bog "No Logo" eller i græsrodsbevægelsen Adbusters ( https://www.adbusters.org/ ), der efterhånden i mange år har udsendt et månedsmagasin med kritik af forbrugersamfundet og al dets reklame og branding. Disse anti-forbrugs og anti-branding bevægelser udspringer af, og er identifikationspunkter...... - den refleksive forbruger skal have noget, der kan "brande" ham som anderledes end alle mainstreamforbrugerne.

Recent Studies of Nucleon Electromagnetic Form Factors

International Nuclear Information System (INIS)

Gilad, Shalev

2010-01-01

The electromagnetic form factors of nucleons are fundamental quantities in nucleon structure. As such, they have been studied extensively both theoretically and experimentally. Significant progress has been made with new measurements at Jlab, MAMI and MIT-Bates, with emphases on expanding the momentum-transfer range and on higher precision. In this paper, we describe the status of this field and present new results from measurements at both low and high momentum transfers. We also compare the experimental data to model predictions, and mention possible implications of the new results to other fields.

Following a broad summary of the author's view of nuclear structure in 1974, he will discuss the key elements they have learned in the past 25 years from the research at the M.I.T. Bates Linear Accelerator center and its sister electron accelerator laboratories. Electron scattering has provided the essential measurements for most of the progress. The future is bright for nuclear structure research as their ability to realistically calculate nuclear structure observables has dramatically advanced and they are increasingly able to incorporate an understanding of quantum chromodynamics into their picture of the nucleus

The proposal achieved many of its objectives. The main area of investigation was the interaction of young planets with surrounding protostellar disks. The grant funds were used to support visits by CoIs and visitors: Gordon Ogilvie, Gennaro D Angelo, and Matthew Bate. Funds were used for travel and partial salary support for Lubow. We made important progress in two areas described in the original proposal: secular resonances (Section 3) and nonlinear waves in three dimensions (Section 5). In addition, we investigated several new areas: planet migration, orbital distribution of planets, and noncoorbital corotation resonances.

A behaviour of the form factors of the nucleon matrix element of the strange quark vector current in the momentum range of the planned measurements in MIT/Bates and CEBAF is predicted theoretically without using any of the experimental information on the nucleon electromagnetic structure. The corresponding leading nonvanishing moments of the nucleon vector strangeness distribution are comparable with the values obtained by other authors in the framework of the method based on the vector meson pole fit of the isoscalar electromagnetic form factors of the nucleon.

We have shown theoretically, in a high pressure, decaying helium plasma, the effect at low energy of inelastic collisions between neutral particles on the population densities of excited molecules and electron-ion recombination coefficient. The formalism of Bates (1962) has been used, taking into account simultaneously collisional mechanisms with electrons, collisional mechanisms with neutrals and radiative processes. The variation of the population densities and electron-ion recombination coefficient with respect to the pressure is given for different values of electron density and temperature. These theoretical results indicate an effect of pressure large enough to be measured and allow us to define the most favorable experimental conditions. (author) [French] L'effet des collisions inelastiques entre particules neutres dans un plasma d'helium, en regime de relaxation, a basse temperature electronique et forte densite de neutres, a ete mis en evidence, theoriquement, aussi bien dans le calcul des densites de population des molecules excitees que dans la determination du coefficient de recombinaison electron-ion. Nous avons utilise le formalisme de Bates (1962) en tenant compte simultanement des mecanismes collisionnels avec les electrons, des mecanismes collisionnels avec les neutres et des phenomenes radiatifs. La variation des densites de population et du coefficient de recombinaison electron-ion en fonction de la pression est donnee pour differentes valeurs de la densite electronique et de la temperature. Ces resultats theoriques laissent prevoir un effet de la pression suffisamment important pour qu'il puisse etre mesure et permettent de definir les conditions experimentales les plus favorables.

The new oxytelluride Ba{sub 3}Yb{sub 2}O{sub 5}Te was obtained from an alkaline earth flux. Ba{sub 3}Yb{sub 2}O{sub 5}Te crystallizes in the tetragonal space group P4/mmm (#123), with a=4.3615(3) Å and c=11.7596(11) Å, Z=1. The structure combines two distinct building blocks, a Ba{sub 2}Yb{sub 2}O{sub 5} perovskite-like double layer with square bipyramidal coordination of the ytterbium ions, and a CsCl-type BaTe layer. Short range magnetic order is apparent at below 5 K, with the magnetic behavior above this temperature dominated by crystal field effects. The structure may be considered as an analog to the Ruddlesden–Popper phases, where the NaCl-type layer has been replaced by the CsCl-type layer. The two-dimensional magnetic behavior is expected based on the highly anisotropic nature of the structure. - Graphical abstract: Optical images of Ba{sub 3}Yb{sub 2}O{sub 5}Te in transmission (left) and reflected (right) light, with atomic unit cell overlay. - Highlights: • Single crystal synthesis and characterization of a new phase, Ba{sub 3}Yb{sub 2}O{sub 5}Te. • The structure features the BaTe high pressure polymorph intergrowth. • Magnetic susceptibility measurements show short range 2 dimensional ordering. • Heat capacity measurements show a feature at the magnetic ordering temperature. • Optical reflectivity measurements show a {sup 2}F{sub 7/2}→{sup 2}F{sub 5/2} absorption at 976 nm.

Fast 4D cone-beam CT from 60 s acquisitions

David C. Hansen

2018-01-01

Full Text Available Background & purpose: Four dimensional Cone beam CT (CBCT has many potential benefits for radiotherapy but suffers from poor image quality, long acquisition times, and/or long reconstruction times. In this work we present a fast iterative reconstruction algorithm for 4D reconstruction of fast acquisition cone beam CT, as well as a new method for temporal regularization and compare to state of the art methods for 4D CBCT. Materials & methods: Regularization parameters for the iterative algorithms were found automatically via computer optimization on 60 s acquisitions using the XCAT phantom. Nineteen lung cancer patients were scanned with 60 s arcs using the onboard image on a Varian trilogy linear accelerator. Images were reconstructed using an accelerated ordered subset algorithm. A frequency based temporal regularization algorithm was developed and compared to the McKinnon-Bates algorithm, 4D total variation and prior images compressed sensing (PICCS. Results: All reconstructions were completed in 60 s or less. The proposed method provided a structural similarity of 0.915, compared with 0.786 for the classic McKinnon-bates method. For the patient study, it provided fewer image artefacts than PICCS, and better spatial resolution than 4D TV. Conclusion: Four dimensional iterative CBCT reconstruction was done in less than 60 s, demonstrating the clinical feasibility. The frequency based method outperformed 4D total variation and PICCS on the simulated data, and for patients allowed for tumor location based on 60 s acquisitions, even for slowly breathing patients. It should thus be suitable for routine clinical use.

1994-06-01

The author describes traditional methods of animal disease control in Belgium and the evolution of these methods up to the present time. Evidence is drawn mainly from Belgian law. The principles of hygienic prophylaxis, which have required little modification over the passage of time, were set out at the beginning of the 18th century by Lancisi and Bates, physicians to Pope Clement XI and King George I of Great Britain, respectively. These principles were immediately incorporated into Belgian law. However, it was not until the second half of the 19th century that they were applied correctly and with success.

The GLAS (Ground-layer Laser Adaptive-optics System) project is to construct a common-user Rayleigh laser beacon that will work in conjunction with the existing NAOMI adaptive optics system, instruments (near IR imager INGRID, optical integral field spectrograph OASIS, coronagraph OSCA) and infrastructure at the 4.2-m William Herschel Telescope (WHT) on La Palma. The laser guide star system will increase sky coverage available to high-order adaptive optics from ~1% to approaching 100% and will be optimized for scientific exploitation of the OASIS integral-field spectrograph at optical wavelengths. Additionally GLAS will be used in on-sky experiments for the application of laser beacons to ELTs. This paper describes the full range of engineering of the project ranging through the laser launch system, wavefront sensors, computer control, mechanisms, diagnostics, CCD detectors and the safety system. GLAS is a fully funded project, with final design completed and all equipment ordered, including the laser. Integration has started on the WHT and first light is expected summer 2006.

Transgressing Boundaries: Belfast and the “Romance-Across-the-Divide”

Directory of Open Access Journals (Sweden)

Stephanie Schwerter

2007-03-01

Full Text Available One of the most popular sub-genres of Northern Irish Troubles fiction is the so called ‘Romance-across-the-divide’, a narrative in which two characters from different religious, cultural and social backgrounds struggle to overcome the region’s sectarian divide. As the centre of the Northern Irish conflict, Belfast epitomises the obstacles posed by the political situation for lovers attempting to defy socio-cultural and denominational boundaries. Joe Cleary argues that in the Northern Irish context the romance narrative is employed to illustrate the possibility of a reconciliation of opposed political camps. This article attempts to refute Cleary’s view. Focussing on Naomi May’s Troubles (1976, Dermot Healy’s A Goat’s Song (1994 and Kate O’Riordan’s Involved (1995 it sets out to demonstrate that unhappy unions of lovers cutting across sectarian lines serve instead largely to depict the ongoing political division within Northern Irish society and the breach between the North and the South of Ireland.

The polarized electron source, which was designed at Yale, features full compatibility with the MIT-Bates accelerator with an injection energy of 365 keV, matching time structures, a approx. 1% duty cycle, and peak beam intensities in the range of 5 to 50 mA peak current. The experimental method utilizes photoemission from a GaAs crystal prepared to have a negative electron affinity in an ultrahigh vacuum system with base pressures of 10 -10 torr or below. A high power continuous wave krypton-ion laser in conjunction with electro-optical instrumentation to chop the beam and to allow random polarization reversal is used as a light source

Fathers’ child-directed speech across two contexts was examined. Father–child dyads from sixty-nine low-income families were videotaped interacting during book reading and toy play when children were 2;0. Fathers used more diverse vocabulary and asked more questions during book reading while their mean length of utterance was longer during toy play. Variation in these specific characteristics of fathers’ speech that differed across contexts was also positively associated with child vocabulary skill measured on the MacArthur-Bates Communicative Development Inventory. Results are discussed in terms of how different contexts elicit specific qualities of child-directed speech that may promote language use and development. PMID:26541647

Structure formation in binary mixtures of surfactants: vesicle opening-up to bicelles and octopus-like micelles

Science.gov (United States)

Noguchi, Hiroshi

Micelle formation in binary mixtures of surfactants is studied using a coarse-grained molecular simulation. When a vesicle composed of lipid and detergent types of molecules is ruptured, a disk-shaped micelle, the bicelle, is typically formed. It is found that cup-shaped vesicles and bicelles connected with worm-like micelles are also formed depending on the surfactant ratio and critical micelle concentration. The obtained octopus shape of micelles agree with those observed in the cryo-TEM images reported in [S. Jain and F. S. Bates, Macromol. 37, 1511 (2004).]. Two types of connection structures between the worm-like micelles and the bicelles are revealed.

Waste management facilities are often shared among different municipalities as a way to manage wastes more efficiently. Usually, management costs are assigned to each municipality considering population or total waste amount, regardless of important environmental aspects such as per capita waste generation or results in composting and recycling. This article presents a fee bate (fee + rebate) system aimed to foster urban waste reduction and recovery. The proposal suggests that municipalities achieving better results in their waste management performance (from an ecological viewpoint) be recompensed with a rebate obtained from a fee charged to those municipalities taking less care of the environment.

Recommended pharmacologic therapies include antiplatelets, angiotensin converting enzyme (ACE inhibitors, and HMG-CoA-reductase inhibitors (statins. Purpose: We studied the degree to which patient admission to a vascular surgery service increased the use of these therapies. Patients and methods: The authors conducted a retrospective chart review of 150 patients with PAD admitted to the vascular surgery service at a large Canadian tertiary care hospital. The use of recommended pharmacologic therapies at the time of admission and discharge were compared. A multidisciplinary clinical team established criteria by which patients were deemed ineligible to receive any of the recommended therapies. Angiotensin receptor blockers (ARBs were considered an alternative to ACE inhibitors. Results: Prior to hospital admission, 64% of patients were on antiplatelet therapy, 67% were on an ACE inhibitor or ARB, and 71% were on a statin. At the time of discharge, 91% of patients were on an antiplatelet (or not, with an acceptable reason, 77% were on an ACE inhibitor or an ARB (or not, with an acceptable reason, and 85% were on a statin (or not, with an acceptable reason.

Full Text Available BACKGROUND: The 1956 paper by DV Bates, JMS Knott and RV Christie, "Respiratory function in emphysema in relation to prognosis" Quart J Med 1956;97:137-157 is largely reprinted with a commentary by the first author, Dr David Bates. Although the pathology of emphysema was well recognized at the time, the clinical diagnosis and assessment of its severity were known to be imprecise; physiological measurements assessing and following the clinical course had not been established. The study aimed to follow systematically a group of patients, selected by clinical criteria using standardized clinical and physiological techniques, over four years and correlate physiological and clinical changes in relation to prognosis and eventually to postmortem findings. Fifty-nine patients were recruited to an emphysema clinic at St Bartholomew's Hospital, London, England. Inclusion criteria were dyspnea without other causes and no cor pulmonale present. Patients' symptoms were assessed by a standardized questionnaire, and measurements were taken of lung volumes, maximal ventilatory volume, carbon monoxide diffusing capacity at rest, exercise and oxygen saturation by oximetry.  During the four years of the study, 17 patients died (actuarial expected - four and 13 presented with signs of pulmonary heart failure. All postmortem examinations (n=9 showed advanced emphysema. A seasonal variation in dyspnea was established (the period included the infamous 1952 London smog. Four patients improved, and the remainder were unchanged or deteriorated. Close relationships were shown between dyspnea and function results, particularly for the diffusing capacity of lungs for carbon monoxide (DLCO. A comparison among a group of patients with chronic bronchitis without dyspnea showed that the DLCO discriminated between them. A loss of the normal increase in DLCO during exercise was shown in emphysema.

Full Text Available Modelos não lineares são adequados para a descrição da liberação de nutrientes, uma vez que estimam quantidades de interesse prático e apresentam boa qualidade de ajuste. Embora seu processo inferencial seja baseado em argumentos assintóticos, existem meios de se conhecer a intensidade da não linearidade. Neste trabalho, avaliou-se a não linearidade de dois modelos de regressão não linear por meio das curvaturas de Bates e Watts, vício de Box e do estudo das propriedades amostrais dos estimadores de mínimos quadrados, obtido por simulação. Os dados são provenientes do estudo, ao longo do tempo, da liberação de K de quatro estercos animais em combinação com dois solos. O modelo Exponencial foi mais adequado, em termos inferenciais e para aplicação prática, uma vez que por todas as medidas apresentou menor não linearidade.Nonlinear models are appropriate to describe nutrient release, since they estimate quantities of practical interest and they have goodness of fit. Although its inferential process is based on asymptotic arguments, there are ways to know the nonlinearity intensity. In this work, we evaluate the nonlinearity of two nonlinear regression models through the curvatures of Bates e Watts, bias of Box and the least squares estimator sampling properties by simulation study. The data are from the study, over time, of the K release from 4 animal manure in combination with 2 soils. The exponential model was more appropriate in terms of inferential and practical aspects, since by all measures showed lower nonlinearity.

The availability of abundant fresh material of Aristeus alcocki Ramadan, 1938 from India allowed the evaluation of the variation in the numbers of photophores on the pereiopods in this species, as well as other diagnostic characters for species discrimination. Although the pereiopodal photophore counts in A. alcocki largely overlap with those of A. semidentatus Bate, 1888, it is found that A. alcocki is unique in the Indo-West Pacific species of the genus by the lower end of the cervical carina considerably farther away from the branchiostegal carina. Molecular genetic analysis confirmed the distinct taxonomic status of the six currently known species in this genus from the Indo-West Pacific and a revised key is provided for distinguishing them.

Nucleon Electromagnetic Form Factors

Energy Technology Data Exchange (ETDEWEB)

Marc Vanderhaeghen; Charles Perdrisat; Vina Punjabi

2007-10-01

There has been much activity in the measurement of the elastic electromagnetic proton and neutron form factors in the last decade, and the quality of the data has greatly improved by performing double polarization experiments, in comparison with previous unpolarized data. Here we review the experimental data base in view of the new results for the proton, and neutron, obtained at JLab, MAMI, and MIT-Bates. The rapid evolution of phenomenological models triggered by these high-precision experiments will be discussed, including the recent progress in the determination of the valence quark generalized parton distributions of the nucleon, as well as the steady rate of improvements made in the lattice QCD calculations.

Chronic disaster syndrome: Displacement, disaster capitalism, and the eviction of the poor from New Orleans.

Adams, Vincanne; VAN Hattum, Taslim; English, Diana

2009-11-01

Many New Orleans residents who were displaced in 2005 by Hurricanes Katrina and Rita and the subsequent levee failures and floods are still displaced. Living with long-term stress related to loss of family, community, jobs, and social security as well as the continuous struggle for a decent life in unsettled life circumstances, they manifest what we are calling "chronic disaster syndrome." The term refers not only to the physiological and psychological effects generated at the individual level by ongoing social disruption but also to the nexus of socioeconomic and political conditions that produce this situation as a long-term and intractable problem. Chronic disaster syndrome emerges from the convergence of three phenomena that create a nexus of displacement: long-term effects of personal trauma (including near loss of life and loss of family members, homes, jobs, community, financial security, and well-being); the social arrangements that enable the smooth functioning of what Naomi Klein calls "disaster capitalism," in which "disaster" is prolonged as a way of life; and the permanent displacement of the most vulnerable populations from the social landscape as a perceived remedy that actually exacerbates the syndrome.

Full Text Available The absolute radiometric calibration of a satellite sensor is the critical factor that ensures the usefulness of the acquired data for quantitative applications on remote sensing. This work presents the results of the first cross-calibration of the sensor on board the Sistema Satelital de Observación de la Tierra (SSOT Chilean satellite or Air Force Satellite FASat-C. RapidEye-MSI was chosen as the reference sensor, and a simultaneous Nadir Overpass Approach (SNO was applied. The biases caused by differences in the spectral responses of both instruments were compensated through an adjustment factor derived from EO-1 Hyperion data. Through this method, the variations affecting the radiometric response of New AstroSat Optical Modular Instrument (NAOMI-1, have been corrected based on collections over the Frenchman Flat calibration site. The results of a preliminary evaluation of the pre-flight and updated coefficients have shown a significant improvement in the accuracy of at-sensor radiances and TOA reflectances: an average agreement of 2.63% (RMSE was achieved for the multispectral bands of both instruments. This research will provide a basis for the continuity of calibration and validation tasks of future Chilean space missions.

Myotragus balearicus (Artiodactyla, Caprinae) is an extinct caprine endemic of the Eastern Balearic Islands or Gymnesics (i.e., Mallorca, Menorca and surrounding islets, Western Mediterranean Sea). In spite of its small size, c. 50cm height at the shoulder, it was the largest mammal inhabiting these islands until the human arrival, and it had peculiar short legs and frontal vision. It disappeared between 2830 and 2210calBCE. The coprolites here studied were recovered from Cova Estreta, in Pollença, Mallorca. The samples were subjected to microscopic examination and enzyme-linked immunosorbent assays (ELISA) for E. histolytica/E. dispar, Giardia intestinalis and Cryptosporidium parvum. This study provides new paleoparasitological data from an extinct animal species of the Holocene period. The microscopy revealed one sample containing uninucleated-cyst of Entamoeba sp., whereas ELISA detected nine positive samples for Cryptosporidium sp. The finding of these protozoans can help in the discussion of its extinction cause and demonstrates the antiquity and the evolutionary history of host-parasite relationships between protozoa and caprines since the Messinian.

Modified method of perturbed stationary states. I

International Nuclear Information System (INIS)

Green, T.A.

1978-10-01

The reaction coordinate approach of Mittleman is used to generalize the method of Perturbed Stationary States. A reaction coordinate is defined for each state in the scattering expansion in terms of parameters which depend on the internuclear separation. These are to be determined from a variational principle described by Demkov. The variational result agrees with that of Bates and McCarroll in the limit of separated atoms, but is generally different elsewhere. The theory is formulated for many-electron systems, and the construction of the scattering expansion is discussed for simple one-, two-, and three-electron systsm. The scattering expansion and the Lagrangian for the radial scattering functions are given in detail for a heteronuclear one-electron system. 2 figures

Full Text Available In two upper-level elective biology courses and one beginning-level general biology course, college students participated in Learning Partnerships with middle or high school classes to study some aspect of biology. The goals were to enhance learning by providing resources to middle and high school students and teachers and by encouraging college students to consider teaching as a learning tool and a possible career goal. The college students designed lessons, activities, and laboratories that were done at the schools and at Bates College. Feedback and data suggest that the partnerships have helped teachers enrich their curricula, enhanced student learning, encouraged additional high school students to consider applying to college, and encouraged college students to consider teaching science.

Where and What Is Pristine Marine Aerosol?

The sources and composition of atmospheric marine aerosol particles have been measured by functional group composition (from Fourier transform infrared spectroscopy) to identify the organic composition of the pristine primary marine (ocean-derived) particles as 65% hydroxyl, 21% alkane, 6% amine, and 7% carboxylic acid functional groups [Frossard et al., 2014a,b]. Pristine but non-primary components from photochemical reactions (likely from biogenic marine vapor emissions) add carboxylic acid groups. Non-pristine contributions include shipping effluent in seawater and ship emissions, which add additional alkane groups (up to 70%), and coastal or continental emissions mix in alkane and carboxylic acid groups. The pristine primary marine (ocean-derived) organic aerosol composition is nearly identical to model generated primary marine aerosol particles from bubbled seawater, indicating that its overall functional group composition is the direct consequence of the organic constituents of the seawater source. While the seawater organic functional group composition was nearly invariant across all three ocean regions studied and the ratio of organic carbon to sodium (OC/Na+) in the generated primary marine aerosol particles remained nearly constant over a broad range of chlorophyll-a concentrations, the generated primary marine aerosol particle alkane group fraction increased with chlorophyll-a concentrations. In addition, the generated primary marine aerosol particles have a hydroxyl group absorption peak location characteristic of monosaccharides and disaccharides, where the seawater hydroxyl group peak location is closer to that of polysaccharides.

Tune-up experiments were carried out at the Bates Linear Accelerator of Middleton, Massachusetts, on the 180 0 electron scattering apparatus designed and constructed by the University of Massachusetts under contract E(11-1)-2545. This apparatus serves as adjunct equipment to the Bates dispersion-matching spectrometer. Form factors were measured for the low-lying states of 27 Al over the momentum transfer range from 0.7 to 2.6 fm -1 . A paper was published in the Physical Review on low-momentum transfer elastic electron scattering from 3 He. The 3 He rms radius was determined to be 1.89 +- 0.05 fm from measurements made at the National Bureau of Standards over the momentum transfer range-squared between 0.032 and 0.34 fm -2 . A Physical Review paper was published in November, 1977, on the results of elastic electron scattering from 25 Mg over the momentum transfer range from 0.19 to 2.56 fm -1 at both forward and backward angles. Values of all of the ground-state multipole moments of both Coulomb and magnetic character were obtained. A paper was submitted for publication on the electroexcitation of giant dipole and quadrupole resonances in 20 Ne. Electric dipole and quadrupole strength was found throughout the region from 12.5 through 25 MeV. About 65% and 100% of the energy-weighted dipole and quadrupole sum rules, respectively, were exhausted. A preliminary run was made on 42 Ca and 44 Ca at the National Bureau of Standards for an incident electron energy of 54.3 MeV and a 145 0 scattering angle in an attempt to observe f/sub 7 / 2 / to f/sub 5 / 2 / magnetic dipole transitions. A paper was composed on the 160 0 inelastic scattering of electrons from 58 Ni at momentum transfers near 2 fm -1 . Strong M8 transitions were observed which are characterized by predominantly one particle--one hole excitations characterized by the configuration

The reaction cross section for 3 He(γ,pd) has been measured using the Saskatchewan-Alberta Large Acceptance Detector (SALAD) with tagged photons in the energy range from 166 to 213 MeV. The energy and angle of the proton and the deuteron were measured with SALAD while the tagger determined the photon energy. Differential cross sections have been determined for 40 degree p * <150 degree. The results are in agreement with the Bonn and Saclay photodisintegration measurements. The most recent photodisintegration measurement performed at Bates is higher by a factor of 1.3, which is just within the combined errors of the experiments. The proton capture results differ by a factor of 1.7 from the present experiment. Comparisons are made with microscopic calculations of the cross sections

This longitudinal study examined growth in the English productive vocabularies of bilingual and monolingual children between ages 24 and 36 months and explored the utility and validity of supplementing parent reports with teacher reports to improve the estimation of children's vocabulary. Low-income, English-speaking and English/Spanish-speaking parents and Early Head Start and Head Start program teachers completed the MacArthur-Bates Communicative Development Inventory, Words and Sentences for 85 children. Results indicate faster growth rates for monolingual than for bilingual children and larger vocabularies for bilingual children who spoke mostly English than mostly Spanish at home. Parent-teacher composite reports, like parent reports, significantly related to children's directly assessed productive vocabulary at ages 30 and 36 months, but parent reports fit the model better. Implications for vocabulary assessment are discussed.

Pregnancy as protest in interwar British women's writing: an antecedent alternative to Aldous Huxley's Brave New World.

Science.gov (United States)

Bigman, Fran

2016-12-01

Accounts that take Aldous Huxley's Brave New World (1932) as representative of interwar reproductive dystopia fail to recognise that the novel expresses both an interest and an anxiety about the possibility of new reproductive technologies to transform sex, gender, and the family that were widely shared by writers in different genres and perhaps expressed best by those likely to be most affected: women. This article explores three earlier works-Charlotte Haldane's Man's World (1926), Vera Brittain's Halcyon, or the Future of Monogamy (1929), and Naomi Mitchison's Comments on Birth Control (1930)-in which pregnancy, instead of figuring as illness or debility, becomes a form of resistance to the status quo. These works engage with biomedicine, however, rather than abjuring it. Through a reading of these works, this article argues that the intersection of medical humanities and science fiction (SF) can enrich both: medical humanities can push SF to go beyond the canon, and SF can challenge any characterisation of literature in the medical humanities as purely fantastical by demonstrating how it responds to the hopes and anxieties of a particular time.

2006-06-01

The new ground layer adaptive optics system (GLAS) on the William Herschel Telescope (WHT) on La Palma will be based on the existing natural guide star adaptive optics system called NAOMI. A part of the new developments is a new control system for the tip-tilt mirror. Instead of the existing system, built around a custom built multiprocessor computer made of C40 DSPs, this system uses an ordinary PC machine and a Linux operating system. It is equipped with a high sensitivity L3 CCD camera with effective readout noise of nearly zero. The software design for the tip-tilt system is being completely redeveloped, in order to make a use of object oriented design which should facilitate easier integration with the rest of the observing system at the WHT. The modular design of the system allows incorporation of different centroiding and loop control methods. To test the system off-sky, we have built a laboratory bench using an artificial light source and a tip-tilt mirror. We present results of tip-tilt correction quality using different centroiding algorithms and different control loop methods at different light levels. This system will serve as a testing ground for a transition to a completely PC-based real-time control system.

In this study, we studied vascular endothelial growth factor (VEGF expression in ­pancreatic adenocarcinoma by immunohistochemical staining. Clinical follow-up and survival data were analyzed. We determined that VEGF was aberrantly overexpressed in a subset of primary pancreatic adenocarcinoma. Statistically, VEGF overexpression was associated with higher stage, higher grade, and lymph node metastasis (P < 0.001, P = 0.012, and P < 0.005, respectively. Additionally, patients of this subset had a much shorter overall survival than patients without VEGF overexpression, as evidenced by Kaplan–Meier plots and the log-rank test (P = 0.001. The 5-year overall survival rate was 17% in patients with VEGF overexpression compared to 52% in patients without VEGF overexpression. The median survival was only 13 months for patients with VEGF overexpression compared to 65 months for patients without. In conclusion, VEGF is a biomarker that identifies a subset of pancreatic ductal adenocarcinoma with aggressive clinical behavior.Keywords: pancreatic adenocarcinoma, VEGF, cancer

Alfred Russel Wallace and the road to natural selection, 1844-1858.

Science.gov (United States)

Smith, Charles H

2015-01-01

Conventional wisdom has had it that the naturalist Alfred Russel Wallace and his colleague Henry Walter Bates journeyed to the Amazon in 1848 with two intentions in mind: to collect natural history specimens, and to consider evidential materials that might reveal the causal basis of organic evolution. This understanding has been questioned recently by the historian John van Wyhe, who points out that with regard to the second matter, at least, there appears to be no evidence of a "smoking gun" variety proving it so. In the present essay the circumstances of Wallace's interest in the matter are reviewed, and van Wyhe is taken to task with alternate explanations for the facts he introduces in his argument. The conclusion is that Wallace almost certainly did have the second objective in mind when he left for both the Amazon, and the Far East.

Aboriginal astronomical traditions from Ooldea, South Australia. Part 1: Nyeeruna and 'The Orion Story'

Science.gov (United States)

Leaman, Trevor M.; Hamacher, Duane W.

2014-07-01

Whilst camped at Ooldea, South Australia, between 1919 and 1935, the amateur anthropologist Daisy Bates CBE recorded the daily lives, lore and oral traditions of the Aboriginal people of the Great Victoria Desert region surrounding Ooldea. Among her archived notes are stories regarding the Aboriginal astronomical traditions of this region. One story in particular, involving the stars making up the modern western constellations of Orion and Taurus, and thus referred to here as 'The Orion Story', stands out for its level of detail and possible references to transient astronomical phenomena. Here, we critically analyse several important elements of 'The Orion Story', including its relationship to an important secret-sacred male initiation rite. This paper is the first in a series attempting to reconstruct a more complete picture of the sky knowledge and star lore of the Aboriginal people of the Great Victoria Desert.

We report on the design and performance of compact detector packages currently installed in the four magnetic out-of-plane spectrometers for electron scattering experiments at the MIT-Bates Linear Accelerator Center. The detector packages have been designed to meet the mechanical requirements arising from out-of-plane particle detection. They offer good trajectory and momentum reconstruction, particle identification and time-of-flight measurements for electrons, pions, protons, and deuterons with large momentum bites and in broad kinematical ranges and high luminosities. The detectors have so far been used with great success in out-of-plane measurements of 12 C(e→,e'p), 2 H(e→,e'p), virtual Compton scattering below pion threshold and in studies of the N→Δ transition in both exclusive reaction channels 1 H(e→,e'p)π 0 and 1 H(e→,e'π + )n

Marchman, Virginia A; Martine-Sussmann, Carmen

2002-10-01

The validity of two analogous caregiver/parent report measures of early language development in young children who are learning both English and Spanish is examined. Caregiver/parent report indices of vocabulary production and grammar were obtained for 26 children using the MacArthur Communicative Development Inventory: Words & Sentences (CDI; Fenson et al., 1994) and the Inventario del Desarrollo de Habilidades Comunicativas: Palabras y Enunciados (IDHC; Jackson-Maldonado, Bates, & Thal, 1992). Scores were significantly correlated with analogous laboratory measures in both English and Spanish, including a real-object naming task and spontaneous language use during free-play. The findings offer evidence that the CDI and IDHC provide valid assessments of early language milestones in young English- and Spanish-speaking children. Factors that may influence the validity of these tools for use with this population are also discussed.

The Waste Safety Testing Facility (WASTEF) was planned in 1978 to test the safety performance of HLW vitrified forms under the simulated conditions of long term storage and disposal, and completed in August 1981. The designed feature of the facility is to treat the vitrified forms contain actual high-level wastes of 5 x 10 4 Ci in maximum with 5 units of concrete shilded hot cells (3 units : Bate-Gamma cells, 2 units : Alpha-Gamma cells) and one units of Alpha-Gamma lead shielded cell, and to store radioactivity of 10 6 Ci in maximum. The safety performance of this facility is fundamentally maintained with confinement of radioactivity and shielding of the radiation. This report describes the method of gamma-ray shielding design, evaluation of the shielding test performed by using sealded gamma-ray sources(Co-60). (author)

The Rhetoric of Sustainability: Perversity, Futility, Jeopardy?

Directory of Open Access Journals (Sweden)

Meg Holden

2010-02-01

Full Text Available In 1991, development economist and American public intellectual Albert O. Hirschman wrote the Rhetoric of Reaction [1]. In this book, which was prescient of more contemporary popular books such as Naomi Klein’s The Shock Doctrine [2] and James C. Scott’s Seeing Like a State [3], Hirschman proposed a way to understand the kinds of arguments made by conservatives about proposals for change. His compelling trilogy of modes of arguments included arguments of perversity, futility, and jeopardy. I argue here that this schema can additionally be used as a way to understand the limits that are seen to exist to approaching sustainable development. I will demonstrate the pervasiveness of arguments that our best attempts to move toward sustainability in our cities today may present threats that are just as grave as those of not acting. This exercise serves two purposes. One is to urge those who would call themselves sustainability scholars to think critically and carefully about the lines of thought and action that may separate different sustainability motivations from the far reaches of interdisciplinary work in this field. The other is to suggest that, because of the persistence of certain kinds of arguments about the impossibility of sustainability, suggestive of deep and enduring instincts of doubt through human history, we should be skeptical of the legitimacy of these claims about the limitations of achieving sustainable development.

Childhood maltreatment may lead to development of future substance use; however the contributions of a family history of substance use is unclear. To better understand the relationship between childhood abuse, family history of alcohol and drug abuse, and injecting drug use initiation in a cohort of chronic opioid users. A cross-sectional survey of long-term and difficult to treat intravenous opiate users of the North American Opiate Medication Initiative (NAOMI) cohort was conducted in two Canadian cities (Vancouver and Montreal). For the analysis, we selected a subsample (n = 87) of the population reported experiencing childhood abuse and completed a 12-month follow up. The sample was 41.4% female and 14.9% First Nations, with a mean age of 38 years. This sample then completed the Childhood Trauma Questionnaire (CTQ) and the Addiction Severity Index (ASI) beside others. Maternal alcohol and drug use was significantly associated with childhood sexual abuse, emotional abuse, and physical neglect. Paternal alcohol and drug use was significantly associated with childhood physical abuse. Increased severity of all types of childhood trauma was related to an earlier age of first injection. CONCLUSIONS/IMPORTANCE: Family history of drug and alcohol use is strongly associated with childhood trauma, which may, in turn, lead to an earlier initiation to the dangerous routes of drug injection.

Polarized electrons from GaAs for parity nonconservation studies and Moeller scattering at 250 MeV

International Nuclear Information System (INIS)

Cates, G.D. Jr.

1987-01-01

A description is given of a polarized electron source based on photoemission from GaAs with circularly polarized light, which was developed for use in the study of parity nonconservation (PNC) in e- 12 C scattering at 250 MeV at the MIT Bates Linear Accelerator Center. A multi-chamber vacuum system houses up to four GaAs crystals simultaneously, and is contained in a Faraday cage to provide 365 KeV in electrostatic acceleration. Stable operation is achieved through the use of a modulated cw laser. The PNC experiment is discussed, particularly with regards to its requirements on the source. The peak current from the source is 20 mA, resulting in a current in excess of 6 mA at high energy. The electron beam polarization has been measured to be 0.36 ± 0.004 using Moeller scattering at 250 MeV

Optically thick model for radiative and collisional effects in nonequilibrium argon plasma flows in a circular tube

International Nuclear Information System (INIS)

Shirai, Hiroyuki; Tabei, Katsuine; Koaizawa, Hisashi.

1984-01-01

Experimental and theoretical studies were made to gain a deeper understanding of the radiative properties of nonequilibrium argon plasma flows in a circular tube. The self-absorption effects were taken into account as rigorously as possible. Experimentally, the radial profiles of the population densities of argon atoms at the excited 4s, 4p, 5p, and 5d levels were obtained from the lateral distributions of the absolute intensities of ArI spectral lines originating from these levels. On the other hand, theoretical profiles of the population densities for the same levels were calculated based on the optically thick model for collisional and radiative processes proposed by Bates et al. and experimentally measured atom temperature, electron temperature, electron density and gas pressure. Comparison of the experimental and theoretical results showed a reasonably good agreement and the importance of the self-absorption effects. (author)

Advances in basic methodologies have played a major role in the dramatic progress in macromolecular crystallography over the past decade, both in terms of overall productivity and in the increasing complexity of the systems being successfully tackled. The 2010 Gordon Research Conference on Diffraction Methods in Structural Biology will, as in the past, focus on the most recent developments in methodology, covering all aspects of the process from crystallization to model building and refinement, complemented by examples of structural highlights and complementary methods. Extensive discussion will be encouraged and it is hoped that all attendees will participate by giving oral or poster presentations, the latter using the excellent poster display area available at Bates College. The relatively small size and informal atmosphere of the meeting provides an excellent opportunity for all participants, especially younger scientists, to meet and exchange ideas with leading methods developers.

Effects of rolling on single-phase water forced convective heat transfer characteristics

International Nuclear Information System (INIS)

Guo Yanming; Gao Puzhen; Huang Zhen

2010-01-01

A series of single-phase forced circulation tests in a vertical tube with rolling motion were performed in order to investigate effects of rolling motion on thermal-hydraulic characteristics. The amplitudes of the rolling motion in the tests were 10 degree, 15 degree and 20 degree. The rolling periods were 7.5 s, 10 s, 15 s and 20 s. The Reynolds number was from 6000 to 15000. Heat transfer in the test tube is bated by the rolling motion. As the test-bed rolling more acutely, the heat transfer coefficient of the test tube becomes smaller when the mass flow rate in the test tube is a constant. The heat transfer coefficient calculated by the formula which is for stable state doesn't fit very well with that from experiments. At last a formula for calculating heat transfer in rolling motion was introduced. (authors)

Myanmar is abundant in lakes and rivers, yet only a few investigations on the fauna of shrimps and prawns have been conducted and no molecular characteristics of prawn species have been described. This study reveals the morphologically identification of five freshwater prawn species under the genus Macrobrachium, including M. cavernicola, M. australiense, M. johnsoni, M. josephi and Macrobrachium sp.WMY-2017. As there was no previous record and information concerning with M. australiense, M. johnsoni, M. josephi and Macrobrachium sp. WMY-2017, they were regarded as the first record from Myanmar. A fragment of Mitochondrial Cytochrome Oxidase I Gene (COI) was amplified successfully from three studied species: M. australiense, M. josephi, and Macrobrachium sp.WMY-2017. The interspecific divergences of studied species varied from 0.01 to 0.15. The phylogenetic tree based on COI fragment sequences showed that M. australiense was closely related to M. rosenbergii, while Macrobrachium sp. WMY-2017 was closest to M. josephi. The results of molecular phylogeny has clarified the relationship within the genus Macrobrachium and represents the first step toward understanding the pattern of speciation base on molecular approach in Myanmar.

Does frequency count? Parental input and the acquisition of vocabulary.

Science.gov (United States)

Goodman, Judith C; Dale, Philip S; Li, Ping

2008-08-01

Studies examining factors that influence when words are learned typically investigate one lexical category or a small set of words. We provide the first evaluation of the relation between input frequency and age of acquisition for a large sample of words. The MacArthur-Bates Communicative Development Inventory provides norming data on age of acquisition for 562 individual words collected from the parents of children aged 0 ; 8 to 2 ; 6. The CHILDES database provides estimates of frequency with which parents use these words with their children (age: 0 ; 7-7 ; 5; mean age: 36 months). For production, across all words higher parental frequency is associated with later acquisition. Within lexical categories, however, higher frequency is related to earlier acquisition. For comprehension, parental frequency correlates significantly with the age of acquisition only for common nouns. Frequency effects change with development. Thus, frequency impacts vocabulary acquisition in a complex interaction with category, modality and developmental stage.

Negative emotionality is considered to be the core of the difficult temperament concept (J. E. Bates, 1989; R. L. Shiner, 1998). In this correlational study, the authors examined whether the relations between children's negative emotionality and problematic behavior (internalizing and externalizing) were partially mediated by parenting style (authoritative and authoritarian) in a community sample of 196 3-year-old children and their mothers. The authors assessed maternal perception of child negative emotionality using the Children's Behavior Questionnaire (M. K. Rothbart, S. A. Ahadi, K. L. Hershey, & P. Fisher, 2001) and assessed problematic child behavior by means of maternal report using the Child Behavior Checklist (T. M. Achenbach, 1992). The results showed that the relations between child negative emotionality and internalizing and externalizing behaviors were partially mediated by mothers' authoritative parenting style. Moreover, when the authors used confirmatory factor analysis to decontaminate possible overlap in item content between measures assessing temperament and problematic behavior, the association between negative emotionality and internalizing behavior was fully mediated by authoritative parenting.

Full Text Available Joshua J Berger, G Wright Bates JrUniversity of Alabama at Birmingham, Department of Obstetrics and Gynecology, Division of Reproductive Endocrinology and Infertility, Birmingham, AL, USAAbstract: The purpose of this paper is to provide a stepwise approach to treating the infertility/subfertility associated with polycystic ovary syndrome. Defining polycystic ovary syndrome in a patient requires first investigating other possible causes for polycystic ovary morphology, acne, hirsutism, obesity, and the metabolic derangements that often accompany polycystic ovary syndrome. Beginning with lifestyle modification and use of metformin, the progressive inclusion of more intensive therapies for induction of ovulation is described. Second-line treatments are discussed and the new findings from a large multicenter trial are discussed in the context of evidence-based treatment strategies for first-line agents. Finally, monofollicular development as a treatment goal and in vitro fertilization are discussed for those with recalcitrant disease.Keywords: polycystic ovary syndrome, infertility, metformin, ovarian drilling, ovulation induction, subfertility

Parity-violating weak neutral current effects in elastic e-12C scattering. Progress report, March 1, 1982-December 31, 1982

International Nuclear Information System (INIS)

Lubell, M.S.

1983-01-01

As a means of investigating unified gauge theories of the electro-weak interaction we have been preparing an experiment for the Bates Electron Accelerator to determine the parity violating asymmetry A = (sigma/sub R/ - sigma/sub L/) for 30 0 elastic scattering by 12 C of 250 MeV longitudinally polarized electrons, where sigma/sub R/ and sigma/sub L/ are respectively the differential cross sections for electrons with right and left helicities. The asymmetry depends strictly on the isoscalar vector-hadronic coupling constant, and in terms of the Weinberg-Salam model is predicted to have a value of approx. 2 x 10 - 6 for our choice of kinematics. Central to the success of the measurement of such a small quantity is the use of an intense, highly stable source of polarized electrons. The progress in the development of such a source, based upon photoemission from GaAs, is reviewed in this report

EBQ code: Transport of space-charge beams in axially symmetric devices

Paul, A. C.

1982-11-01

Such general-purpose space charge codes as EGUN, BATES, WODF, and TRANSPORT do not gracefully accommodate the simulation of relativistic space-charged beams propagating a long distance in axially symmetric devices where a high degree of cancellation has occurred between the self-magnetic and self-electric forces of the beam. The EBQ code was written specifically to follow high current beam particles where space charge is important in long distance flight in axially symmetric machines possessing external electric and magnetic field. EBQ simultaneously tracks all trajectories so as to allow procedures for charge deposition based on inter-ray separations. The orbits are treated in Cartesian geometry (position and momentum) with z as the independent variable. Poisson's equation is solved in cylindrical geometry on an orthogonal rectangular mesh. EBQ can also handle problems involving multiple ion species where the space charge from each must be included. Such problems arise in the design of ion sources where different charge and mass states are present.

Kell, J

1999-01-01

The sensitivity of momentum distributions, recoil polarization observables, and response functions for nucleon knockout by polarized electron scattering to channel coupling in final-state interactions is investigated using a model in which both the distorting and the coupling potentials are constructed by folding density-dependent nucleon-nucleon effective interactions with nuclear transition densities. Elastic reorientation, inelastic scattering, and charge exchange are included for all possible couplings within the model space. Calculations for sup 1 sup 6 O are presented for 200 and 433 MeV ejectile energies, corresponding to proposed experiments at MAMI and TJNAF, and for sup 1 sup 2 C at 70 and 270 MeV, corresponding to experiments at NIKHEF and MIT-Bates. The relative importance of charge exchange decreases as the ejectile energy increases, but remains significant for 200 MeV. Both proton and neutron knockout cross sections for large recoil momenta, p sub m greater than 300 MeV/c, are substantially affe...

However, there is a bate among muslim scholar and mufasir about the meaning of al-Qurû. It’s because al-Qurû is one of the sentence of al-Adhdâd wich has two meaning, especially in the Qur’an, namely haid (menstruation and thahr. One of the most popular muslim scholar who concern in Qur’an and Arabic is al-Anbari with his book al-Adhdâd. Al-Anbari explains that Qurû has two meanings, First, al-Qurû in etymology is the form of Jama’ from aqra and qurû. Second, al-Qurû has a meaning of menstruation, thahr, or the period of iddah as a sign of being allowed to remarry after certain period of time.

Event-Based Prospective Memory Is Resistant but Not Immune to Proactive Interference.

Oates, Joyce M; Peynircioglu, Zehra F

2016-01-01

Recent evidence suggests that proactive interference (PI) does not hurt event-based prospective memory (ProM) the way it does retrospective memory (RetroM) (Oates, Peynircioglu, & Bates, 2015). We investigated this apparent resistance further. Introduction of a distractor task to ensure we were testing ProM rather than vigilance in Experiment 1 and tripling the number of lists to provide more opportunity for PI buildup in Experiment 2 still did not produce performance decrements. However, when the ProM task was combined with a RetroM task in Experiment 3, a comparable buildup and release was observed also in the ProM task. It appears that event based ProM is indeed somewhat resistant to PI, but this resistance can break down when the ProM task comprises the same stimuli as in an embedded RetroM task. We discuss the results using the ideas of cue overload and distinctiveness as well as shared attentional and working memory resources.

The nucleon generalized polarizabilities (GPs), probed in virtual Compton scattering (VCS), describe the spatial distribution of the polarization density in a nucleon. They are accessed experimentally via the process of electron-proton bremsstrahlung (ep → epγ) at electron-beam facilities, such as MIT-Bates, CEBAF (Jefferson Lab), and MAMI (Mainz). We present the calculation of the nucleon GPs and VCS observables at next-to-leading order in baryon chiral perturbation theory (BχPT), and confront the results with the empirical information. At this order our results are predictions, in the sense that all the parameters are well known from elsewhere. Within the relatively large uncertainties of our calculation we find good agreement with the experimental observations of VCS and the empirical extractions of the GPs. We find large discrepancies with previous chiral calculations - all done in heavy-baryon χPT (HBχPT) - and discuss the differences between BχPT and HBχPT responsible for these discrepancies. (orig.)

Spontaneous acoustic emission of a corrugated shock wave in the presence of a reflecting surface

International Nuclear Information System (INIS)

Wouchuk, J.G.; Lopez Cavada, J.

2004-01-01

An analytic model to study perturbation evolution in the space between a corrugated shock and a piston surface is presented. The conditions for stable oscillation patterns are obtained by looking at the poles of the exact Laplace transform. It is seen that besides the standard D'yakov-Kontorovich (DK) mode of oscillation, the shock surface can exhibit an additional finite set of discrete frequencies, due to the interaction with the piston which reflects sound waves from behind. The additional eigenmodes are excited when the shock is launched at t=0 + . The first eigenmode (the DK mode) is always present, if the Hugoniot curve has the correct slope in the V-p plane. However, the additional frequencies could be excited for strong enough shocks. The predictions of the model are verified for particular cases by studying a van der Waals gas, as in the work of Bates and Montgomery [Phys. Fluids 11, 462 (1999); Phys. Rev. Lett. 84, 1180 (2000)]. Only acoustic emission modes are considered

The impact of transaction trust on consumers' intentions to adopt m-commerce: a cross-cultural investigation.

Kao, Danny Tengti

2009-04-01

Mobile commerce (M-commerce) has been acknowledged as one of the most representative transaction types driving e-commerce worldwide; however, the potential security threats that keep consumers from M-commerce still confound the M-commerce industry. This research attempts to explore two questions: What are the dimensions of transaction trust that may significantly affect consumers' intentions to adopt M-commerce, and what are the cultural dimensions that may significantly moderate the impact of transaction trust on consumers' intentions to adopt M-commerce? A research framework based on the BATE model and Hofstede's cultural dimensions was established to identify how transaction trust and cultural value affect consumers' intentions to adopt M-commerce. Results revealed that transaction trust significantly affects consumers' intentions to adopt M-commerce. However, while uncertainty avoidance moderates the impacts of business trust and security on consumers' intentions of M-commerce adoption, both individualism/collectivism and long-term/short-term orientation moderate the relationship between security trust and consumers' intentions of M-commerce adoption.

We report new precise H(e,e ' p)π 0 measurements at the Δ(1232) resonance at Q 2 =0.127 (GeV/c) 2 obtained at the MIT-Bates out-of-plane scattering facility which are particularly sensitive to the transverse electric amplitude (E2) of the γ * N→Δ transition. The new data have been analyzed together with those of earlier measurements to yield precise quadrupole to dipole amplitude ratios: Re(E 1+ 3/2 /M 1+ 3/2 )=(-2.3±0.3 stat+syst ±0.6 model )% and Re(S 1+ 3/2 /M 1+ 3/2 )=(-6.1±0.2 stat+syst ±0.5 model )% for M 1+ 3/2 =(41.4±0.3 stat+syst ±0.4 model )(10 -3 /m π + ). The derived amplitudes give credence to the conjecture of deformation in hadrons favoring, at low Q 2 , the dominance of mesonic effects.

Towards 4D intervention guidance using compressed sensing

Interventional radiology is nowadays usually guided with projection radiography using mono- or biplane systems. Due to the projective nature of this guidance imaging certain intraprocedural situations remain unclear. Although helpful, the use of 3D CT is limited due to radiation dose. Using advanced reconstruction techniques incorporating prior knowledge, one could overcome these limitations without exceeding dose limitations. Intervention guidance is especially appealing to those algorithms, because certain constrains apply to useful images in intervention guidance that vary relevantly from other CT applications. These are: key relevance of high contrast structures, sparse temporal updates and little relevance of absolute CT values. In this paper the principal usability of reconstruction algorithms for intervention guidance is tested. Compressed sensing algorithms PICCS and ASD-POCS are compared to the McKinnon-Bates and Feldkamp-Davis-Kress algorithm. Animal experiments as well as simulations are performed. An outlook towards 4D intervention guidance is provided. (orig.)

Full Text Available The separation of the upper dermal of the skin (the papillary layer or grain from the lower dermis (corium is regarded as a defect in leather making. It is difficult to detect pelts at an early processing stage and it only becomes really apparent once the skin is made into leather. There would be great advantages in detecting the problem at the pickled pelt stage (skins treated with sodium sulphide and lime, bated with enzymes, and then preserved in NaCl and sulphuric acid so that adjustments to the processing could be made to mitigate the effect. A novel bio-sensor for inspection of leather in a non-invasive way has been fabricated and developed. The sensor has the planar Interdigital structure and the consecutive fingers are connected to positive and negative electrodes respectively. The experimental results show that the sensor has a great potential to estimate the leather quality in a non-invasive and non-destructive way.

Full Text Available This paper presents an adaptation of the MacArthur-Bates Communicative Development Inventories (short version into three languages spoken in Southern Mozambique. The tool was adapted to study vocabulary development among children of 12 to 25 months of age in two communities: a rural, monolingual Changana speaking community and an urban bilingual Ronga and Portuguese speaking community. We present a norming study carried out with the adaptation, as well as a validation study. The norming study revealed various predictors for reported expressive and receptive vocabulary size. These predictors include age, socioeconomic status, reported health problems, caregiving practices, and location. The validation of the CDI among a small sample in both communities shows positive correlations between the reported expressive vocabulary scores and children’s recorded word production. We conclude that the adapted CDI is useful for research purposes and could be used as a template for adaptations into other languages from similar cultures.

Non-Archimedean reaction-ultradiffusion equations and complex hierarchic systems

We initiate the study of non-Archimedean reaction-ultradiffusion equations and their connections with models of complex hierarchic systems. From a mathematical perspective, the equations studied here are the p-adic counterpart of the integro-differential models for phase separation introduced by Bates and Chmaj. Our equations are also generalizations of the ultradiffusion equations on trees studied in the 1980s by Ogielski, Stein, Bachas, Huberman, among others, and also generalizations of the master equations of the Avetisov et al models, which describe certain complex hierarchic systems. From a physical perspective, our equations are gradient flows of non-Archimedean free energy functionals and their solutions describe the macroscopic density profile of a bistable material whose space of states has an ultrametric structure. Some of our results are p-adic analogs of some well-known results in the Archimedean setting, however, the mechanism of diffusion is completely different due to the fact that it occurs in an ultrametric space.

Although these discourses construct disability differently, three of them – the lay, charity and medical discourses – tend to view disability negatively. This article endeavours to challenge the stereotypical “picture” of a person with a disability. By conducting an intrinsic case study the unique intrapersonal assets of a boy (who has a physical disability, spina bifida is identified. An asset-based approach accompanied the research design as a theoretical framework in order to explore whether positive aspects of this boy’s life-world could be identified. This article identifies and embraces the positive side of living with a physical disability and illustrates ways in which positive constructions of an individual with disabilities can be pursued.

This work is a continuation of our systematic study of the solubility of pharmaceuticals (Pharms). All substances here are derivatives of anthranilic acid, and have an anti-inflammatory direction of action (niflumic acid, flufenamic acid, and diclofenac sodium). The basic thermal properties of pure Pharms, i.e., melting and glass-transition temperatures as well as the enthalpy of melting, have been measured with the differential scanning microcalorimetry technique (DSC). Molar volumes have been calculated with the Barton group contribution method. The equilibrium mole fraction solubilities of three pharmaceuticals were measured in a range of temperatures from 285 to 355 K in three important solvents for Pharm investigations: water, ethanol, and 1-octanol using a dynamic method and spectroscopic UV-vis method. The experimental solubility data have been correlated by means of the commonly known G(E) equation: the NRTL, with the assumption that the systems studied here have revealed simple eutectic mixtures. pK(a) precise measurement values have been investigated with the Bates-Schwarzenbach spectrophotometric method. © 2011 American Chemical Society

Full Text Available Only one, long-term sustainable source of competitive advantage exist: the intellectual capital that resides in the minds of people. The ongoing development of people as strategic assets is essential because of three defining forces of our time: globalisation, the information revolution, and the speed of change. Each of these forces is examined in the article against the backdrop of some important changes in the psychological contract. The challenge is to create knowledge for practical solutions, appropriate to a changing world of work. Opsomming Slegs een, lang termyn, standhoudende bron van mededingendheid bestaan: die intellektuele kapitaal wat in mense weggelê is.

Elk van hierdie kragte word bespreek in die artikel teen die agtergrond van beduidende verskuiwings in die sielkundige kontrak. Die uitdaging is om kennis vir praktiese oplossings te skep wat op ’n veranderende wêreld van werk van toepassing sal wees.

Parity violating weak neutral-current effects in elastic e-12C scattering. Progress report, April 15, 1981-February 28, 1982

Unified gauge theories of the electro-weak interaction incorporate a neutral weak current, which, although many orders of magnitude smaller than the neutral-electromagnetic current, can be isolated through the manifestation of its parity violating effects. As a consequence, neutral current parity violation experiments provide direct access to the measurement of the weak coupling constants as well as fundamental tests of the unified theories. The verification of unified theories at low energies is a crucial prerequisite of the application of these theories to the range of higher energies where the W+- and the Z 0 are predicted to exist. One highly sensitive measurement of parity violation in the neutral current sector is provided by the determination of the asymmetry, A = (sigma + - sigma - )/(sigma + + sigma - ), for elastic scattering of positive (+) and negative (-) helicity electrons from 12 C nuclei. We have been pursuing such a program at the Bates Electron Accelerator with the goal of measuring A to a precision of approx. 10 -7 . By contrast, the standard model predicts a value for A of approx. 2 x 10 -6

Summary Antioxidant (AO) capacity of chocolates with 27, 44 and 75% cocoa was assessed after production and during twelve months of storage by direct current (DC) polarographic assay, based on the decrease of anodic current caused by the formation of hydroxo-perhydroxyl mercury(II) complex (HPMC) in alkaline solutions of hydrogen peroxide at potentials of mercury oxidation, and two spectrophotometric assays. Relative antioxidant capacity index (RACI) was calculated by taking the average value of the AO assay (the sample mass in all assays was identical). Oxidative stability of chocolate fat was determined by differential scanning calorimetry. Measured parameters and RACI were correlated mutually and with the content of total phenols (Folin-Ciocalteu assay), flavan-3-ols (vanillin and p-dimethylaminocinnamaldehyde assay) and proanthocyanidins (modified Bate-Smith assay). During storage, the studied functional and health-related characteristics remained unchanged. Amongst applied AO assays, the DC polarographic one, whose validity was confirmed by two-way ANOVA and F-test, correlated most significantly with oxidative stability (oxidation onset temperature and induction time). In addition, principal component analysis was applied to characterise chocolate types. PMID:27904388

Torii, S.; Yano, T.; Iino, N.

2005-01-01

The aim of the present study is to predict a ground surface temperature (GST) of Kagoshima Prefecture in Kyushu Island, Japan, by using LANDSAT-5/TM and NOAA-11/AVHRR digital data. Image processing procedure is employed to aid in evaluating GST, in which the thermal images of AVHRR bands 4 and 5 are analysed. Emphasis is placed on the prediction accuracy of the existing atmospheric correlation equations taking the atmospheric attenuation effect into account, which are proposed by Tamba et. al., Bates and Diaz, and Sakkaida and Kawamura. It is disclosed that (I) the factor of the zenith angle need to be taken into account when the accurate GST is evaluated by using the atmospheric correction equations, (ii) that of Sakaida and Kawamura has better accuracy, (iii) LANDSAT-5/TM data contains a very high resolution level of the land, the estimated land surface temperature is higher than the measured value, and (iv) improved accuracy of the surface temperature is achieved if LANDSAT-5/TM data are used together with NOAA-11/AVHRR.

There is a dearth of assessments of sign language development in young deaf children. This study gathered age-related scores from a sample of deaf native signing children using an adapted version of the MacArthur-Bates CDI (Fenson et al., 1994). Parental reports on children's receptive and expressive signing were collected longitudinally on 29 deaf native British Sign Language (BSL) users, aged 8-36 months, yielding 146 datasets. A smooth upward growth curve was obtained for early vocabulary development and percentile scores were derived. In the main, receptive scores were in advance of expressive scores. No gender bias was observed. Correlational analysis identified factors associated with vocabulary development, including parental education and mothers' training in BSL. Individual children's profiles showed a range of development and some evidence of a growth spurt. Clinical and research issues relating to the measure are discussed. The study has developed a valid, reliable measure of vocabulary development in BSL. Further research is needed to investigate the relationship between vocabulary acquisition in native and non-native signers.

Averett, T; McKeown, R D; Pitt, M

1999-01-01

A piezo-electrically controlled optical correction system was successfully used to reduce the helicity-correlated pulse-to-pulse position differences of a laser spot to better than +-100 nm at a pulse rate of 600 Hz. Using a simple feedback algorithm, average position differences of DELTA x-bar=-3.5+-4.2 nm and DELTA y-bar=2.6+-6.6 nm were obtained over a 6 h period. This optical correction system was successfully used in the polarized electron source at the Bates Linear Accelerator Center to stabilize the position of the electron beam during the recent SAMPLE experiment. Because this experiment measures a parity violating signal at the 10 sup - sup 6 level, it is sensitive to systematic effects which are correlated with the helicity of the incident electrons. One potentially large systematic effect is the helicity-correlated motion of the incident electron beam. By using this optical correction system, electron beam position differences at the location of the experiment were routinely kept well below +-100 n...

1981-01-01

An experimental investigation of a stacked plasma generator of Maecker type has been performed at low pressures (25 - 760 Torr) and low electric currents (10 - 60 A) for argon gas. Radial distributions of electron density and electron temperature were obtained by measuring the intensities of spectral lines and continuum from cylindrically confined plasmas. Based on such data of the macroscopic plasma parameters, the SAHA equilibrium relation, and the collisional and radiative theory of BATES et al., the spatial extent of equilibrium region and nonequilibrium effects of electronic excitation of the atom have been examined. In the plasmas generated in the apparatus, electron temperature ranged from 7,500 to 11,000 0 K and electron density 7 x 10 14 to 3 x 10 16 cm -3 . It was found that thermochemical equilibrium conditions existed only in the vicinity of the tube axis even at relatively high pressures and high currents, and the higher excited levels than the 5p level of argon atom were always in SAHA equilibrium with free electrons.

Although there has been much debate over the content of children's first words, few large sample studies address this question for children at the very earliest stages of word learning. The authors report data from comparable samples of 265 English-, 336 Putonghua- (Mandarin), and 369 Cantonese-speaking 8- to 16-month-old infants whose caregivers completed MacArthur-Bates Communicative Development Inventories and reported them to produce between 1 and 10 words. Analyses of individual words indicated striking commonalities in the first words that children learn. However, substantive cross-linguistic differences appeared in the relative prevalence of common nouns, people terms, and verbs as well as in the probability that children produced even one of these word types when they had a total of 1-3, 4-6, or 7-10 words in their vocabularies. These data document cross-linguistic differences in the types of words produced even at the earliest stages of vocabulary learning and underscore the importance of parental input and cross-linguistic/cross-cultural variations in children's early word-learning.

Taxonomic revision of doubtful Brazilian freshwater shrimp species of genus Macrobrachium (Decapoda, Palaemonidae

Directory of Open Access Journals (Sweden)

Leonardo G. Pileggi

Full Text Available The freshwater prawns of the genus Macrobrachium Spence Bate, 1868 are widely distributed in rivers of tropical and subtropical regions and represent an interesting group with controversial taxonomy. The morphological characters traditionally used to separate species have shown a high intraspecific variation. Doubts about the status of M. birai Lobão, Melo & Fernandes, 1986, M. holthuisi Genofre & Lobão, 1978 and M. petronioi Melo, Lobão & Fernandes, 1986 have been arisen due to the high resemblance of the former two species with M. olfersi (Wiegmann, 1836, and the latter one with M. potiuna (Müller, 1880. Therefore, we performed a detailed morphological analysis of these species, including new characters not usually used in the species recognition. The present results here with molecular data lead us to conclude that M. birai and M. holthuisi are junior synonyms of M. olfersi, and M. petronioi is a junior synonym of M. potiuna. Considering these synonymies, 17 valid species are now reported for the Brazilian territory.

Recirculating accelerator driver for a high-power free-electron laser: A design overview

International Nuclear Information System (INIS)

Bohn, C.L.

1997-01-01

Jefferson Lab is building a free-electron laser (FEL) to produce continuous-wave (cw), kW-level light at 3-6 μm wavelength. A superconducting linac will drive the laser, generating a 5 mA average current, 42 MeV energy electron beam. A transport lattice will recirculate the beam back to the linac for deceleration and conversion of about 75% of its power into rf power. Bunch charge will range up to 135 pC, and bunch lengths will range down to 1 ps in parts of the transport lattice. Accordingly, space charge in the injector and coherent synchrotron radiation in magnetic bends come into play. The machine will thus enable studying these phenomena as a precursor to designing compact accelerators of high-brightness beams. The FEL is scheduled to be installed in its own facility by 1 October 1997. Given the short schedule, the machine design is conservative, based on modifications of the CEBAF cryomodule and MIT-Bates transport lattice. This paper surveys the machine design

Precise measurement of the neutron magnetic form factor from quasielastic 3 rvec He(rvec e,e')

International Nuclear Information System (INIS)

Gao, H.

1997-01-01

Polarized 3 He targets have proven to be a useful tool for studying the electric and magnetic form factors of the neutron, and the spin structure of the neutron. The neutron magnetic form factor at low Q 2 was determined previously at MIT-Bates from the quasielastic 3 rvec He(rvec e, e ' ) process. New experiment was planned at TJNAF to systematically measure the inclusive 3 He quasielastic transverse asymmetry, A T ' , at Q 2 = 0.1 - 0.5 (GeV/c) 2 with high statistical and systematic accuracy. A 2% statistical uncertainty is aimed at all the pro- posed values of Q 2 , and 3% systematic uncertainty for A T ' can be achieved for this experiment. The precise data will constrain theoretical calculations of 3 He quasielastic asymmetry. Furthermore, the neutron magnetic form factor at Q 2 = 0.1 - 0.5 (GeV/c) 2 will be extracted from the measured asymmetries with an overall uncertainty of 2%. Precise measurements of G n M at low Q 2 will resolve the discrepancy among the existing data in the same Q 2 region

Electron accelerators for research at the frontiers of nuclear physics

Grunder, H.A.; Hartline, B.K.; Corneliussen, S.T.

1986-01-01

Electron accelerators for the frontiers of nuclear physics must provide high duty factor (>80%) for coincidence measurements; few-hundred-MeV through few-GeV energy for work in the nucleonic, hadronic, and confinement regimes; energy resolution of ∼10 -4 ; and high current (≥ 100 μA). To fulfill these requirements new machines and upgrades of existing ones are being planned or constructed. Representative microtron-based facilities are the upgrade of MAMI at the University of Mainz (West Germany), the proposed two-stage cascaded microtron at the University of Illinois (USA), and the three-stage Troitsk ''polytron'' (USSR). Representative projects to add pulse stretcher rings to existing linacs are the upgrades at MIT-Bates (USA) and at NIKHEF-K (Netherlands). Recent advances in superconducting rf technology, especially in cavity design and fabrication, have made large superconducting cw linacs become feasible. Recirculating superconducting cw linacs are under construction at the University of Darmstadt (West Germany) and at CEBAF (USA), and a proposal is being developed at Saclay (France). 31 refs

Reclaiming value from academic labor: commentary by the Editors of Human Geography

Directory of Open Access Journals (Sweden)

John C. Finn

2017-12-01

Full Text Available There have long been discussions about the need for an alternative publishing model for academic research. This has been made clear by the September 2017 scandal involving Third World Quarterly. The editor’s deeply problematic decision to publish an essay arguing in favor of colonialism was likely meant as click-bate to drive clicks and citations. But we should not lose sight of the fact that this latest scandal is only one recent manifestation of a long-simmering problem that has periodically commanded significant attention in the academic literature, blogs, email lists, conference sessions, and the popular press. As a direct result, over the last decade or more, new journals have been created that specifically endeavor to offer routes around corporate/capitalist academic publishing, and several existing journals have removed themselves from this profit-driven ecosystem. In this commentary, the editorial team of the journal Human Geography weighs in on what we see as the nature of the problem, what we are doing in response, what our successes have been, and what challenges remain.

2017-02-01

We investigated the potential relationship between maternal depressive symptoms during the postpartum period and non-verbal communication skills of infants at 14 months of age in a birth cohort study of 951 infants and assessed what factors may influence this association. Maternal depressive symptoms were measured using the Edinburgh Postnatal Depression Scale, and non-verbal communication skills were measured using the MacArthur-Bates Communicative Development Inventories, which include Early Gestures and Later Gestures domains. Infants whose mothers had a high level of depressive symptoms (13+ points) during both the first month postpartum and at 10 weeks were approximately 0.5 standard deviations below normal in Early Gestures scores and 0.5-0.7 standard deviations below normal in Later Gestures scores. These associations were independent of potential explanations, such as maternal depression/anxiety prior to birth, breastfeeding practices, and recent depressive symptoms among mothers. These findings indicate that infants whose mothers have postpartum depressive symptoms may be at increased risk of experiencing delay in non-verbal development. Copyright © 2016 Elsevier Inc.

The temperature dependences of the N2+ + N2 → N4+ and O2+ + O2 → O4+ association reactions

Boehringer, H.; Arnold, F.; Smith, D.; Adams, N.G.

1983-01-01

The temperature dependencies of three body association reactions have been investigated in attempts to elucidate the mechanisms of ion-molecule association. The variation with temperature of the three-body rate coefficients is described usually as a power law k approximately Tsup(-n). Experience has shown that with measurements over limited temperature ranges as with previous methods the derived coefficients n are wrong and measurements over large temperature ranges are desirable. The selected ion flow-tube and the drift tube methods developed in Birmingham and Heidelberg provide measurements over (overlapping) wide temperature rang. In collaboration of the Birmingham and the Heidelberg group the He stabilized reactions N 2 + + N 2 + He → N 4 + + He and O 2 + + O 2 + He → O 4 + + He reactions over 30 to 600 deg K. A power law dependence is found above 100 K. The temperature dependencies of the rate constants are interpred and used as a critical test of recent theories of association reactions by D.R. Bates and E. Herbst. (G.Q.)

Assessing the Pathogenic Ability of Ralstonia pseudosolanacearum (Ralstonia solanacearum Phylotype I from Ornamental Rosa spp. Plants

Full Text Available Ralstonia pseudosolanacearum (Ralstonia solanacearum phylotype I isolates found in stunted, yellowing, and wilted ornamental rose (Rosa spp. were assessed for their pathogenic ability in two rose cultivars (cv. “Armando” and cv. “Red Naomi” and in four solanaceous crops: tomato (Solanum lycopersicum cv. “Money Maker”, tobacco (Nicotiana tabacum cv. “White Burley”, eggplant (Solanum melongena cv. “Black Beauty” and sweet pepper (Capsicum annum cv. “Yolo Wonder”. Significant differences were observed in susceptibility between the two rose cultivars as well as between the two modes of inoculation performed. The cultivar “Armando” was significantly more susceptible than cultivar “Red Naomi,” exhibiting higher disease severity and incidence. Similarly, stem inoculation after wounding was found to be significantly more effective than soil drenching, resulting in higher disease severity. Additionally, a temperature dependency in susceptibility was observed for both cultivars irrespective of the mode of inoculation, however, this was significantly more pronounced upon soil drenching. The solanaceous crops all showed to be susceptible to the R. pseudosolanacearum isolates originated from the Rosa spp. plants. Furthermore, both rose cultivars were able to harbor symptomless infections with other R. pseudosolanacearum and R. solanacearum isolates than those isolated from rose. Our results clearly demonstrated that latent infections in a rose cultivar such as cv. “Red Naomi” do occur even at temperatures as low as 20°C. This latency poses high risks for the entire floricultural industry as latently infected Rosa spp. plants are propagated and distributed over various continents, including areas where climatic conditions are optimal for the pathogen.

Living with the label "disability": personal narrative as a resource for responsive and informed practice in biomedicine and bioethics.

Science.gov (United States)

Bishop, Jeffery; Sunderland, Naomi

2013-01-01

What is it like to live with the label "Disability?" NIB editorial staff and narrative symposium editors, Jeffery Bishop and Naomi Sunderland developed a call for stories, which was sent to several list serves, shared with the 1000 Voices Project community and posted on Narrative Inquiry in Bioethics' website. The request for personal stories from people who identify with the label "disabled" asked them to: consider how the label "disability" interacts with other aspects of their life in health care settings; does the term "disability" reflect their actual embodied experiences of impairment or does it fail to do justice to their particular experience of impairment; describe the kind of experiences that are possible because of the impairment(s); discuss how the label has affected their "authentic voice"; and many other concepts about what effects the label has on their lives. These authors share deeply personal experiences that will help readers understand their world, challenges, and joys. Thirteen stories are found in the print version of the journal and an additional five supplemental stories are published online only through Project MUSE. The stories are complemented by four commentary articles by Elizabeth R. Schiltz; Lorna Hallahan; Nicole Matthews, Kathleen Ellem, and Lesley Chenoweth; and Jeffery Bishop, Rachelle Barina, and Devan Stahl. These scholars come from the disciplines of law, social work, media studies, medicine, and bioethics from Australia and the United States. Together, the symposium's storytellers and commentators offer striking and informative insights into the everydayness of living with disabilities.

Full Text Available Benoit Deschamps1, Naomi Musaji2, John A Gillespie21SFBC Anapharm, Montreal, Canada; 2Strativa Pharmaceuticals, a division of Par Pharmaceutical, Inc., Woodcliff Lake, NJ, USAObjective: Megestrol acetate oral suspension (MAOS is an appetite stimulant indicated for cachexia in patients with AIDS. It is available in its original formulation, Megace® (MAOS, and as a nanocrystal dispersion, Megace® ES (MA-ES. Three studies were conducted to evaluate the pharmacokinetic properties of these formulations under fed and fasting conditions.Methods: An open-label, crossover trial was conducted in 24 healthy males randomized to MA-ES 625 mg/5 mL given with a high-calorie, high-fat meal, or after an overnight fast. Blood samples were drawn at multiple time points and pharmacokinetic parameters were determined. Two separate, open-label reference studies evaluated MAOS 800 mg/20 mL in 40 fed or 40 fasting healthy male volunteers.Results: In fasting MA-ES subjects, the average maximum concentration (Cmax was 30% less than the fed Cmax value. For MAOS, fasting Cmax was 86% less than fed Cmax. In fasting subjects, the area under the curve was 12,095 ng⋅h/mL for MA-ES, and 8,942 ng⋅h/mL for MAOS. In fed subjects, the absorption of the two formulations was comparable.Conclusion: Bioavailability and absorption are greater for MA-ES than MAOS in fasting subjects. MA-ES may be a preferred formulation of megestrol acetate when managing cachectic patients whose caloric intake is reduced.Keywords: megestrol acetate, bioavailability, cachexia, nanocrystal technology, appetite stimulant

Applied gamma ray spectrometry and remote sensing in delineation of nepheline syenites in rift tectonic settings

2017-04-01

The United Nations (2016) observes that 'Neglected Development Minerals' including industrial minerals such as nepheline syenites have great potential for sustainable development, yet their exploitation has not been equally promoted like high value minerals. Nepheline syenites have great potential as alternative potassium (K) silicate fertiliser, as well as a source of Rare Earths. Demand for K fertiliser keeps rising by 3-3.5% annually (Jena et al., 2014) due to increased need to replace K removal from the soil (Sheldrick et al., 2002). The situation is most critical in Sub-Sahara Africa where nutrient loss due to intensive farming accounts to 22kg N, 2.5 kg P and 15 kg of K per hectare annually (Keeble, 2012). Ironically, Africa with 15% of global population, which is also expected to double by 2040 (Manning, 2015), uses only 1.5% of global K fertiliser. In this study, we use recently acquired countrywide airborne geophysical gamma ray data of Malawi (Bates & Mechennef, 2013) and satellite remote sensing data to identify nepheline syenites, suitable as sources of K silicate fertilizer, in rift tectonic settings. Initial focus was on the East African Rift System (EARS) starting with Malawi. Results from these two techniques are compared with X-ray fluorescence (XRF) geochemical analyses of sample collected from fieldwork in some potential areas of Malawi. With lessons from the Rochagem movement (Theodoro & Leonardos, 2006), identification of novel alternative potash sources in Africa will greatly benefit millions of farmers in developing countries, especially in Sub Sahara Africa where fertiliser costs are very high. Considering that high-resolution airborne geophysical data is not available in many African countries due to high costs associated with data acquisition campaigns, alternative and effective remote sensing approaches for delineating nepheline syenite rocks are necessary.

In 2006, Algerian Space Agency (ASAL) decided to design and built two optical Earth observation satellites. The first one, ALSAT-2A, was integrated and tested as a training and cooperation program with EADS Astrium. The second satellite ALSAT-2B will be integrated by ASAL engineers in the Satellite Development Center (CDS) at Oran in Algeria. On 12th July 2010, Algeria has launched ALSAT-2A onboard an Indian rocket PSLV-C15 from the Sriharikota launch base, Chennaï. ALSAT-2A is the first Earth observation satellite of the AstroSat-100 family; the design is based on the Myriade platform and comprising the first flight model of the New Astrosat Observation Modular Instrument (NAOMI). This Instrument offers a 2.5m ground resolution for the PAN channel and a 10m ground resolution for four multi-spectral channels which provides high imaging quality. The operations are performed from ALSAT-2 ground segment located in Ouargla (Algeria) and after the test phase ALSAT-2A provides successful images. ALSAT-2A electrical power subsystem (EPS) is composed of a Solar Array Generator (SAG ), a Li-ion battery dedicated to power storage and energy source during eclipse or high consumption phases and a Power Conditioning and Distribution Unit (PCDU). This paper focuses primarily on ALSAT-2A electrical power subsystem behavior during Launch and Early OPeration (LEOP) as well as In Orbit Test (IOT). The telemetry data related to the SAG voltage, current and temperature will be analyzed in addition to battery temperature, voltage, charge and discharge current. These parameters will be studied in function of satellite power consumption.

Vocabulary is a domain of particular challenge for many children with autism spectrum disorder (ASD). Recent research has drawn attention to ways in which lexical characteristics relate to vocabulary acquisition. The current study tested the hypothesis that lexical characteristics account for variability in vocabulary size of young children with ASD, applying the extended statistical learning theory of vocabulary delay in late talkers (Stokes, Kern, & Dos Santos, 2012) to toddlers with ASD. Parents reported the words produced by toddlers with ASD (n = 57; age 21-37 months) or toddlers without ASD (n = 41; age 22-26 months) on the MacArthur-Bates Communicative Development Inventories. The average phonological neighborhood density, word frequency, and word length of each toddler's lexicon were calculated. These lexical characteristics served as predictors of vocabulary size. Findings differed for toddlers with and without ASD and according to subsamples. Word length was the most consistent predictor of vocabulary size for toddlers with ASD. Distinct relationships between lexical characteristics and vocabulary size were observed for toddlers with and without ASD. Experimental studies on distributional cues to vocabulary acquisition are needed to inform what is known about mechanisms of learning in neurodevelopmental disorders.

The authors sought to provide an initial evaluation of the hypothesis that corporal punishment is less strongly associated with parental emotion and impulsivity among African American ("Black") in contrast to European American ("White") parents. White-Latino and Black-Latino differences in corporal punishment, emotion, and impulsivity were explored, given the lack of existing theory predicting group differences. Couples with 3- to 7-year-old children were recruited via random digit dialing, and the parents completed questionnaires and an analog parent-child conflict task in the laboratory. Group differences were tested pooling mothers and fathers via dyadic data analyses. Black parents (N = 57) had more positive attitudes toward and used more corporal punishment than White parents (N = 730). Latino American parents' (N = 78) views and use of corporal punishment were similar to those of White parents. By and large, associations of corporal punishment with parents' impulsivity and emotion did not significantly vary by race/ethnicity. The present findings, although preliminary, do not support the emotion-impulsivity hypothesis of racial differences in the use of corporal punishment suggested by K. Deater-Deckard, K. A. Dodge, J. E. Bates, and G. S. Pettit (1996).

A prospective, randomized, placebo-controlled clinical trial was conducted to compare the healing effectiveness of Alkanna tinctoria (L.) Tausch (Boraginaceae) with standard dressing on wound healing at the donor site after removal of the skin graft. Enrolled patients were randomly allocated to receive topicalA. tinctoria extract ointment (20%) or standard dressing (dressing with base ointment) daily. Wound healing was assessed using the Bates-Jenson assessment tool at the 2 nd and 4 th weeks after intervention. Decreases in wound score were significantly greater in the A. tinctoria group compared with the placebo group (P <0.05). The surface areas of graft donor sites in the A. tinctoria group were significantly reduced as compared with the control group at day 28 of the intervention (P < 0.05). The proportion of patients in the A. tinctoria group achieving complete wound healing within 2 to 4 weeks was 50% and 96.66%, respectively, significantly higher than in patients receiving standard care: 0% and 23.3%, respectively. This clinical study showed that A. tinctoria dressing accelerates wound healing after graft harvesting. IRCT ID: IRCT201511165781N2 .

The purpose of this study was to investigate cultural differences between Danish and American children at 2 and 3 years as measured with the developmental test Bayley-III, and to investigate the Bayley-III Language Scale validity. The Danish children (N = 43) were tested with the Bayley-III and their parents completed an additional language questionnaire (the MacArthur-Bates CDI). Results showed that scores from the Danish children did not differ significantly from the American norms on the Cognitive or Motor Scale, but the Danish sample scored significantly higher on the Language Scale. A comparison of the Bayley-III Language subtests with the CDI showed that the two measures correlated significantly, but the percentile score from the CDI was significantly higher than the percentile score from the Bayley-III Language subtests. This could be because the two instruments measure slightly different areas of language development, or because the Bayley-III overestimates language development in Danish children. However, due to the limitations of the current study, further research is needed to clarify this issue. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

2017-09-01

Parity Violating Electron Scattering (PVES) is an extremely successful precision frontier tool that has been used for testing the Standard Model (SM) and understanding nucleon structure. Several generations of highly successful PVES programs at SLAC, MIT-Bates, MAMI-Mainz, and Jefferson Lab have contributed to the understanding of nucleon structure and testing the SM. But missing phenomena like matter-antimatter asymmetry, neutrino flavor oscillations, and dark matter and energy suggest that the SM is only a `low energy' effective theory. The MOLLER experiment at Jefferson Lab will measure the weak charge of the electron, QWe = 1 - 4sin2θW , with a precision of 2.4 % by measuring the parity violating asymmetry in electron-electron () scattering and will be sensitive to subtle but measurable deviations from precisely calculable predictions from the SM. The MOLLER experiment will provide the best contact interaction search for leptons at low OR high energy makes it a probe of physics beyond the Standard Model with sensitivities to mass-scales of new PV physics up to 7.5 TeV. Overview of the experiment and recent pre-R&D progress will be reported.

Full Text Available Resumo O artigo trata das representações acerca das práticas homoeróticas masculinas entre usuários de dois ambientes virtuais: as salas de bate-papo do portal UOL e a rede social Manhunt. Pode-se perceber uma tensão entre um modelo baseado na matriz heterossexual, que alinha ativo a masculino e passivo a feminino, e outro que busca afirmar a masculinidade, independente da posição sexual, tentando apagar a marca de afeminação, inclusive daquele que ocupa a posição de passivo no sexo. Porém, entrevistas com alguns dos usuários e experiências pessoais, além de postagens dos próprios participantes em que debatem o mercado homoerótico on-line, demonstram como o jogo das classificações é situacional e oscilante: meu argumento é que o trânsito do discurso na rede e na vida "real" não permite que engessemos as categorias; as performatividades que se desenrolam no universo virtual são sempre incompletas e abertas a falhas e deslocamentos.

Geology is defined as the 'study of the planet Earth - the materials of which it is made, the processes that act on these materials, the products formed, and the history of the planet and its life forms since its origin' (Bates and Jackson, 1976). Remote sensing has seen a number of variable definitions such as those by Sabins and Lillesand and Kiefer in their respective textbooks (Sabins, 1996; Lillesand and Kiefer, 2000). Floyd Sabins (Sabins, 1996) defined it as 'the science of acquiring, processing and interpreting images that record the interaction between electromagnetic energy and matter' while Lillesand and Kiefer (Lillesand and Kiefer, 2000) defined it as 'the science and art of obtaining information about an object, area, or phenomenon through the analysis of data acquired by a device that is not in contact with the object, area, or phenomenon under investigation'. Thus Geological Remote Sensing can be considered the study of, not just Earth given the breadth of work undertaken in planetary science, geological features and surfaces and their interaction with the electromagnetic spectrum using technology that is not in direct contact with the features of interest.

Commercial citrus groves in two counties at the Northwestern Paraná state were evaluated to estimate the disease progression by using parameterizations of nonlinear models. Groves of Citrus sinensis Osbeck, variety “Pêra”, “Valência”, “Natal” and “Folha Murcha” had all the plants evaluated for the presence of disease symptoms. Thereafter, different parameterizations of the Logistic and Gompertz models were fitted to these data. The goodness of fit was evaluated by the intrinsic (IN and parameter-effects (PE curvatures of Bates and Watts, the bias of Box and the Hougaard measures of skewness. In Loanda, the best model was the Fermi-Dirac, and in Nova Esperança the data were best fitted to the parameterization L5, which is also a parameterization from the Logistic model.A citricultura é afetada por diversas doenças, dentre as quais a Clorose Variegada dos Citros (CVC causada pela bactéria Xylella fastidiosa (Wells.

Aquaculture diseases, particularly Vibriosis, are becoming a pressing concern due to incurred aquacultural loss in China. Commercial antibiotics may be used to control it, but its increased antibiotic resistance to prominent pathogenic bacteria has become a prevalent problem nationwide, and a global threat to public health. Probiotics are recommended instead because they are healthy, environment-friendly, and capable of maintaining productivity. An antibacterium against Vibrio harveyi 11593 was isolated from a mariculture pond with shrimp, crabs, and shellfish in China. The bacterium, E14, has an inhibitory zone diameter (DIZ) of 24.5 ± 0.5 mm. The strain was identified as Bacillus pumilus based on morphological observation, conventional biochemical tests, and 16S rDNA sequence analysis. The gram-positiveand motile bacterium is around 1.10-1.32 pm × 0.67-0.83 μm in size. Optimized conditions for antimicrobial substance production of B. pumilus E14 require that it be cultured for 26 h at 28 °C, with an initial pH of 7.0 in 100 mL/500 mL LB with 3% NaCl. The B. pumilus E14 cultures were confirmed to be safe and efficacious and actually worked to protect the host animal in shrimp larvae (Penaeus chinensis) culture. The B. pumilus E14 obtained in this study strengthened the strain's defense against aquaculture disease and made a good candidate for an alternative probiotics and benefit to sustainability of aquaculture.

Purpose Vocabulary assessment holds promise as a way to identify young bilingual children at risk for language delay. This study compares 2 measures of vocabulary in a group of young Spanish–English bilingual children to a single-language measure used with monolingual children. Method Total vocabulary and conceptual vocabulary were used to measure mean vocabulary size and growth in 47 Spanish–English bilingually developing children from 22 to 30 months of age based on results from the MacArthur–Bates Communicative Development Inventory (CDI; Fenson et al., 1993) and the Inventario del Desarrollo de Habilidades Comunicativas (Jackson-Maldonado et al., 2003). Bilingual children’s scores of total vocabulary and conceptual vocabulary were compared with CDI scores for a control group of 56 monolingual children. Results The total vocabulary measure resulted in mean vocabulary scores and average rate of growth similar to monolingual growth, whereas conceptual vocabulary scores were significantly smaller and grew at a slower rate than total vocabulary scores. Total vocabulary identified the same proportion of bilingual children below the 25th percentile on monolingual norms as the CDI did for monolingual children. Conclusion These results support the use of total vocabulary as a means of assessing early language development in young bilingual Spanish–English speaking children. PMID:24023382

Electron scattering experiments are in progress at the Bates Linear Accelerator in Middleton, Massachusetts. Both magnetic elastic and transverse inelastic scattering cross sections have been measured at 180 0 by the apparatus constructed and brought into operation in late 1977 by the University of Massachusetts. A liquid-nitrogen-cooled gas target is being used in a study of deuteron elastic scattering and electrodisintegration over a large energy range. A measurement of elastic magnetic and transverse inelastic scattering from 14 N has been started. Measurements of the elastic magnetic scattering from 13 C, 15 N, 27 Al, 29 Si, and 31 P have been completed. The data set on 15 N inelastic scattering are now complete and analysis of the data is in progress. A study of M8 transitions in 54 Fe and 60 Ni is nearing completion. A measurement of the transverse quasielastic scattering from 56 Fe has been started. Planning for an experiment utilizing radioactive 14 C is underway. Large-basis shell model calculations pertaining to the above nuclei and others have been made. Theoretical calculations of exchange currents, nuclear convection currents, and other nuclear phenomena are in progress. Finally, considerations are being given to the design of an integrated storage-ring-experimental system

Shakespeare and Warwickshire Dialect

Directory of Open Access Journals (Sweden)

Rosalind Barber

2016-03-01

Full Text Available The article investigates whether Shakespeare used Warwickshire, Cotswold or Midlands dialect, focusing on the sources of recent claims by Bate, Kathman and Wood, most of which derive from early dialect dictionaries compiled by 18th and 19th century antiquarians. It determines that all of these claims – frequently used as a defence against the Shakespeare authorship question – fall into four categories: those based on errors of fact, well-known or widely-used words, poetic inventions, and those derived through circular reasoning. Two problems are identified. Firstly, the source texts on which these dialect claims rest were written two- to three-hundred years after the plays, by which time language use would not only have evolved, but would have been influenced by Shakespeare. Secondly, the continuing academic taboo surrounding the authorship question has meant that these claims, though easily refuted by searching the Oxford English Dictionary and the digitized texts of EEBO, have gone unchallenged in academia. It demonstrates that querying the validity of arguments derived from an assumed biography can – without in any way disproving that the man from Stratford wrote the body of works we call ‘Shakespeare’ – lead to a better understanding of the way Shakespeare actually used language, and the meanings he intended.

2018-01-01

Four-dimensional cone beam computed tomography allows for temporally resolved imaging with useful applications in radiotherapy, but raises particular challenges in terms of image quality and computation time. The purpose of this work is to develop a fast and accurate 4D algorithm by adapting a GPU-accelerated ordered subsets convex algorithm (OSC), combined with the total variation minimization regularization technique (TV). Different initialization schemes were studied to adapt the OSC-TV algorithm to 4D reconstruction: each respiratory phase was initialized either with a 3D reconstruction or a blank image. Reconstruction algorithms were tested on a dynamic numerical phantom and on a clinical dataset. 4D iterations were implemented for a cluster of 8 GPUs. All developed methods allowed for an adequate visualization of the respiratory movement and compared favorably to the McKinnon-Bates and adaptive steepest descent projection onto convex sets algorithms, while the 4D reconstructions initialized from a prior 3D reconstruction led to better overall image quality. The most suitable adaptation of OSC-TV to 4D CBCT was found to be a combination of a prior FDK reconstruction and a 4D OSC-TV reconstruction with a reconstruction time of 4.5 minutes. This relatively short reconstruction time could facilitate a clinical use.

Urban and suburban malaria in Rondônia (Brazilian Western Amazon II: perennial transmissions with high anopheline densities are associated with human environmental changes

Luiz Herman Soares Gil

2007-06-01

Full Text Available Longitudinal entomological surveys were performed in Vila Candelária and adjacent rural locality of Bate Estaca concomitantly with a clinical epidemiologic malaria survey. Vila Candelária is a riverside periurban neighborhood of Porto Velho, capital of the state of Rondônia in the Brazilian Amazon. High anopheline densities were found accompanying the peak of rainfall, as reported in rural areas of the region. Moreover, several minor peaks of anophelines were recorded between the end of the dry season and the beginning of the next rainy season. These secondary peaks were related to permanent anopheline breeding sites resulting from human activities. Malaria transmission is, therefore, observed all over the year. In Vila Candelária, the risk of malaria infection both indoors and outdoors was calculated as being 2 and 10/infecting bites per year per inhabitant respectively. Urban malaria in riverside areas was associated with two factors: (1 high prevalence of asymptomatic carriers in a stable human population and (2 high anopheline densities related to human environmental changes. This association is probably found in other Amazonian urban and suburban communities. The implementation of control measures should include environmental sanitation and better characterization of the role of asymptomatic carriers in malaria transmission.

In order to obtain the optimum conditions for micro-hardness measurements of sintered UO 2 , two kinds of hardness tests (Vickers and Knoop) were examined with non-irradiated UO 2 of 2.5 and 5 μm in grain size. The hardness values were obtained as a function of the applied load in the load range of 25 -- 1,000 g. In the Vickers test, cracks were generated around the periphery of an indentation even at lower load of 50 g, which means the Vickers hardness is not suitable for UO 2 specimens. In the Knoop test, three stages of load dependence were observed for sintered pellet as well as for a single crystal by Bates. Load dependence of Knoop hardness and crack formation were discussed. In the range of applied load around 70 -- 100 g there were plateau region where hardness values were nearly unchanged and did not contain any cracks in the indentation. The plateau region represents a hardness of a specimen. From a comparison between the hardness values of 2.5 μm and those of 5 μm UO 2 , it was approved that the degree of sintering controls the hardness in the plateau region. (author)

In the present study, we isolated a trypsin-producing strain DMN6 from the leather waste and identified it as Bacillus licheniformis through a two-step screening strategy. The trypsin activity was increased up to 140 from 20 U/mL through culture optimization. The enzyme was purified to electrophoretic homogeneity with a molecular mass of 44 kDa by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and the specific activity of purified enzyme is 350 U/mg with Nα-Benzoyl-L-arginine ethylester as the substrate. The optimum temperature and pH for the trypsin are 65 °C and pH 9.0, respectively. Also, the enzyme can be significantly activated by Ba(2+). This enzyme is relatively stable in alkaline environment and displays excellent activity at low temperatures. It could retain over 95% of enzyme activity after 180 min of incubation at 45 °C. The distinguished activity under low temperature and prominent stability enhance its catalytic potential. In the current work, the open reading frame was obtained with a length of 1371 nucleotides that encoded a protein of 456 amino acids. These data would warrant the B. licheniformis trypsin as a promising candidate for catalytic application in collagen preparation and leather bating through further protein engineering.

Full Text Available Although President Donald Trump has built personal relationship with President Xi Jinping since the Mar-a-Lago summit in April 2017, the conflicts between the two countries remain. The U.S. is worried about if it is able to continue maintaining its status of the global power and the dominant power in Asia while China is dramatically expanding its global influence. A new U.S. National Security Strategy labels China as a “competitor” challenging American interests. There is speculation that a war between the U.S. and China is inevitable. Will both the U.S. and China be able to maintain a healthy competition to avoid a war? How will the U.S. manage the new type of relations with a rising China? This paper will address these questions and argue that although the stakes are as high as ever for the United States and China to manage their relations, the conflicts between the two countries are manageable (Bates, 2005. Both the U.S. and China do not have any choice, but to understand each other and learn how to deal with their competitors. China-U.S. relations will be gradually getting better after the Trump administration works more with China.

Full Text Available In the present study, we isolated a trypsin-producing strain DMN6 from the leather waste and identified it as Bacillus licheniformis through a two-step screening strategy. The trypsin activity was increased up to 140 from 20 U/mL through culture optimization. The enzyme was purified to electrophoretic homogeneity with a molecular mass of 44 kDa by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and the specific activity of purified enzyme is 350 U/mg with Nα-Benzoyl-l-arginine ethylester as the substrate. The optimum temperature and pH for the trypsin are 65 °C and pH 9.0, respectively. Also, the enzyme can be significantly activated by Ba2+. This enzyme is relatively stable in alkaline environment and displays excellent activity at low temperatures. It could retain over 95% of enzyme activity after 180 min of incubation at 45 °C. The distinguished activity under low temperature and prominent stability enhance its catalytic potential. In the current work, the open reading frame was obtained with a length of 1371 nucleotides that encoded a protein of 456 amino acids. These data would warrant the B. licheniformis trypsin as a promising candidate for catalytic application in collagen preparation and leather bating through further protein engineering.

Full Text Available El lenguaje del niño tiene unas características específicas y singulares que lo diferencian del lenguaje adulto. En este artículo abordamos el estudio del lenguaje de los niños de dos grupos: normales y con Necesidades Educativas Especiales (N.E.E. en centros específicos, desde la perspectiva del modelo funcional. La funcionalidad lingüística es un modelo de análisis que nos permite reflexionar sobre el lenguaje, ya que estudia el lenguaje en uso partiendo de la realidad concreta del acto lingüístico centrándose en la pragmática del discurso y analizando el lenguaje cómo lo utiliza el individuo. En este modelo, la intencionalidad comunicativa es el eje que marca la esencia de los análisis de los actos de habla.

Correlates of receptive-expressive vocabulary size discrepancies may provide insights into why language development in children with autism spectrum disorder (ASD) deviates from typical language development and ultimately improve intervention outcomes. We indexed receptive-expressive vocabulary size discrepancies of 65 initially preverbal children with ASD (20-48 months) to a comparison sample from the MacArthur-Bates Communicative Development Inventories Wordbank (Frank, Braginsky, Yurovsky, & Marchman, 2017) to quantify typicality. We then tested whether attention toward a speaker and oral motor performance predict typicality of the discrepancy 8 months later. Attention toward a speaker correlated positively with receptive-expressive vocabulary size discrepancy typicality. Imitative and nonimitative oral motor performance were not significant predictors of vocabulary size discrepancy typicality. Secondary analyses indicated that midpoint receptive vocabulary size mediated the association between initial attention toward a speaker and end point receptive-expressive vocabulary size discrepancy typicality. Findings support the hypothesis that variation in attention toward a speaker might partially explain receptive-expressive vocabulary size discrepancy magnitude in children with ASD. Results are consistent with an input-processing deficit explanation of language impairment in this clinical population. Future studies should test whether attention toward a speaker is malleable and causally related to receptive-expressive discrepancies in children with ASD.

Application of social domain of human mind in water management

Science.gov (United States)

Piirimäe, Kristjan

2010-05-01

Currently, researches dispute whether a human reasons domain-generally or domain-specifically (Fiddick, 2004). The theory of several intuitive reasoning programmes in human mind suggests that the main driver to increase problem-solving abilities is social domain (Byrne & Bates, 2009). This theory leads to an idea to apply the social domain also in environmental management. More specifically, environmental problems might be presented through social aspects. Cosmides (1989) proposed that the most powerful programme in our social domain might be ‘cheater detection module' - a genetically determined mental tool whose dedicated function is to unmask cheaters. She even suggested that only cheater detection can enable logical reasoning. Recently, this idea has found experimental proof and specifications (Buchner et al., 2009). From this perspective, a participatory environmental decision support system requires involvement of the representatives of social control such as environmental agencies and NGOs. These evaluators might effectively discover legal and moral inconsistencies, logical errors and other weaknesses in proposals if they are encouraged to detect cheating. Thus, instead of just environmental concerns, the query of an artificial intelligence should emphasize cheating. Following the idea of Cosmides (1989), employment of cheater detectors to EDSS might appear the only way to achieve environmental management which applies correct logical reasoning as well as both, legislative requirements and conservationist moral. According to our hypothesis, representatives of social control can well discover legal and moral inconsistencies, logical errors and and other weaknesses in envirionmental management proposals if encouraged for cheater detection. In our social experiment, a draft plan of measures for sustainable management of Lake Peipsi environment was proposed to representatives of social control, including Ministry of Environment, other environmental authorities

Full Text Available This study revealed that the scientific interest in the genus Macrobrachium was not restricted to a biological point of view, but included also social and economic aspects. Many species of the genus are subject of traditional fisheries and culture worldwide. Several research groups across the globe have developed projects in various subject areas on commercial or non-commercial native species of this genus. This investigation aimed to contribute to the development of the genus Macrobrachium research through a scientometric study. The study was based on publications (1980 to 2013 registered in the following databases: Biological Abstracts, ISI Web of Science, SciELO Citation Index, BioOne, Science Direct, Scopus, and Redalyc. A total of 2165 publications on Macrobrachium in the last 33 years were included in this analysis. The themes that yielded most posts were related to culture, nutrition/feeding, and genetics with almost 60% of the total. Publications concerning M. rosenbergii represented more than 60% of the total with the remaining 40% encompassing 22 other species. Analysis performed by geographical regions evidenced that Latin America produced 23% of the publications, South Asia 22%, and East Asia 16%. Brazil generated 65% of the percentage mentioned for the Latin American region. It is necessary to strengthen research on topics of basic biology, especially those of native species. This will allow rapid progress in the generation of production technologies sustained by a solid biological knowledge base.

Rock formation characterization for carbon dioxide geosequestration: 3D seismic amplitude and coherency anomalies, and seismic petrophysical facies classification, Wellington and Anson-Bates Fields, Kansas, USA

Higher resolution rock formation characterization is of paramount priority, amid growing interest in injecting carbon dioxide, CO2, into subsurface rock formations of depeleting/depleted hydrocarbon reservoirs or saline aquifers in order to reduce emissions of greenhouse gases. In this paper, we present a case study for a Mississippian carbonate characterization integrating post-stack seismic attributes, well log porosities, and seismic petrophysical facies classification. We evaluated changes in petrophysical lithofacies and reveal structural facies-controls in the study area. Three cross-plot clusters in a plot of well log porosity and acoustic impedance corroborated a Neural Network petrophysical facies classification, which was based on training and validation utilizing three petrophysically-different wells and three volume seismic attributes, extracted from a time window including the wavelet of the reservoir-top reflection. Reworked lithofacies along small-throw faults has been revealed based on comparing coherency and seismic petrophysical facies. The main objective of this study is to put an emphasis on reservoir characterization that is both optimized for and subsequently benefiting from pilot tertiary CO2 carbon geosequestration in a depleting reservoir and also in the deeper saline aquifer of the Arbuckle Group, south central Kansas. The 3D seismic coherency attribute, we calculated from a window embracing the Mississippian top reflection event, indicated anomalous features that can be interpreted as a change in lithofacies or faulting effect. An Artificial Neural Network (ANN) lithofacies modeling has been used to better understand these subtle features, and also provide petrophysical classes, which will benefit flow-simulation modeling and/or time-lapse seismic monitoring feasibility analysis. This paper emphasizes the need of paying greater attention to small-scale features when embarking upon characterization of a reservoir or saline-aquifer for CO2 based carbon geosequestration.

This study was conducted to determine the distribution, abundance, and demography of a wood boring isopod, Sphaeroma terebrans Bate, 1866, within the prop roots of the red mangrove, Rhizophora mangle L., in eight sites within Tampa Bay, Florida. Sphaeroma terebrans in Tampa Bay displayed reproductive activity year-round and bay-wide synchrony in their density pattern. On average approximately 60% (range: 25%-86%) of the intertidal aerial roots surveyed were occupied by S. terebrans. Although infestation levels by S. terebrans in Tampa Bay were similar to that of more tropical regions, the distribution of S. terebrans was not continuous throughout the study sites. A substantially higher occurrence and density of S. terebrans was found in the northern compared to more southern study sites within the Bay. Additionally, some seemingly suitable areas of the bay (i.e., Pinellas Point, Skyway, Fort Desoto) were actually unoccupied on some dates. Although sites differed in the frequency with which roots were attacked, the density of burrows and isopods in an occupied root was similar, with most attacked roots containing 3-5 burrows. The results of a transplantation experiment indicated that neither abiotic factors nor substrate quality limit the burrowing capabilities or survival of adult S. terebrans in the areas where they are absent. Instead, dispersal limitation, linked with differential juvenile survival, most likely controls isopod distribution and abundance within Tampa Bay.

After a certain ceiling has been reached (i.e. around $ 10,000), an increase in average income in any one country will not lead to increased personal happiness. Such additional earnings are, in all probability, expended rather on satisfying relative needs. Cars with a low fuel efficiency (big cars, and cars with powerful engines) possibly satisfy more relative needs than absolute needs. This is why a general trend towards more economical vehicles does not or hardly leads to a reduction in contentment: relative needs satisfaction, coupled with the status aspect, does not need to suffer from this. lt is the satisfying of relative needs and the emergence of status effects in consumption that is responsible for inefficient market functioning because of the occurrence of consumption externalities. There is therefore a welfare economic argument for adhering to a regulatory policy in which the consumption of relatively low status goods is encouraged while the consumption of relatively high status goods is discouraged. In view of the sharp price increases required to make the national car volume substantially more economical and in order to survive the considerable resistance that will be put up to such price rises, it might be preferable to introduce policies like `fee-bates` or negotiable rights rather than to wield price policies directed at effecting a trend in the direction of more economical car usage. 24 refs.

Electron scattering experiments are in progress at the Bates Linear Accelerator in Middleton, Massachusetts. Both magnetic elastic and transverse inelastic scattering cross sections have been measured at 180 0 by the apparatus constructed and brought into operation in late 1977 by the University of Massachusetts. A liquid-nitrogen-cooled gas target is being used in a study of deuteron elastic magnetic scattering and electrodisintegration over a large energy range. A measurement of elastic magnetic and transverse inelastic scattering from 14 N has been started. Measurements of the elastic magnetic scattering from 13 C, 15 N, 27 Al, 29 Si, and 31 P have been completed. The data set on 15 N inelastic scattering are now complete and analysis of the data is in progress. A study of M8 transitions in 54 Fe and 60 Ni is nearing completion. Several papers are being written on these subjects. A measurement of the transverse quasi-elastic scattering from 56 Fe has been started. Planning for an experiment utilizing radioactive 14 C is underway. Large-basis shell model calculations pertaining to the above nuclei and others have been made. Theoretical calculations of exchange currents, nuclear convection currents, and other nuclear phenomena are in progress. Finally, considerations are being given to the design of an integrated storage-ring-experimental system

Can connectionism save constructivism?

Science.gov (United States)

Marcus, G F

1998-05-01

Constructivism is the Piagetian notion that learning leads the child to develop new types of representations. For example, on the Piagetian view, a child is born without knowing that objects persist in time even when they are occluded; through a process of learning, the child comes to know that objects persist in time. The trouble with this view has always been the lack of a concrete, computational account of how a learning mechanism could lead to such a change. Recently, however, in a book entitled Rethinking Innateness. Elman et al. (Elman, J.L., Bates, E., Johnson, M.H., Karmiloff-Smith, A., Parisi, D., Plunkett, K., 1996. Rethinking Innateness: A Connectionist Perspective on Development. Cambridge, MA: MIT Press) have claimed that connectionist models might provide an account of the development of new kinds of representations that would not depend on the existence of innate representations. I show that the models described in Rethinking Innateness depend on innately assumed representations and that they do not offer a genuine alternative to nativism. Moreover, I present simulation results which show that these models are incapable of deriving genuine abstract representations that are not presupposed. I then give a formal account of why the models fail to generalize in the ways that humans do. Thus, connectionism, at least in its current form, does not provide any support for constructivism. I conclude by sketching a possible alternative.

To examine the effects of observed maternal sensitivity (MS), cognitive stimulation (CS), and linguistic stimulation on the 4-year growth of oral language in young, deaf children receiving a cochlear implant. Previous studies of cochlear implants have not considered the effects of parental behaviors on language outcomes. In this prospective, multisite study, we evaluated parent-child interactions during structured and unstructured play tasks and their effects on oral language development in 188 deaf children receiving a cochlear implant and 97 normal-hearing children as controls. Parent-child interactions were rated on a 7-point scale using the National Institute of Child Health and Human Development's Early Childcare Study codes, which have well-established psychometric properties. Language was assessed using the MacArthur Bates Communicative Development Inventories, the Reynell Developmental Language Scales, and the Comprehensive Assessment of Spoken Language. We used mixed longitudinal modeling to test our hypotheses. After accounting for early hearing experience and child and family demographics, MS and CS predicted significant increases in the growth of oral language. Linguistic stimulation was related to language growth only in the context of high MS. The magnitude of effects of MS and CS on the growth of language was similar to that found for age at cochlear implantation, suggesting that addressing parenting behaviors is a critical target for early language learning after implantation.

In this research, the seeds provided by Technology Research Institute of Osaka Prefecture and Nomura Plating Co., Ltd., relative to their plating processes using ion exchange membranes and metal anodes are utilized. Efforts are made to prolong the bathing life of the Ni-W alloy plating solution, to put the plating bath in an enclosure, to develop a chromium-free plating technology wherewith bating life is longer, environmental impact is smaller, and resistance to corrosion is higher, and experiments and tests are conducted for industrialization and for the practical application of the developed technologies. At Technology Research Institute of Osaka Prefecture, electrolytic Ni-W alloy plating was taken up. An insoluble anode separated from the plating solution by a cation exchange membrane and plural metal anodes were brought into a new process and, into the same, novel technologies were further introduced, which were a metal ion supply method in which the distribution of current to 3 anodes was regulated and the employment of a sacrificial anode decomposition agent. The new process was investigated for its validity and difficulties. Furthermore, Ni-W-P alloy plating was studied and a mirror-like Ni-W-P alloy plate was developed in a phosphorous acid added bath without detriment to the non-waste solution plating process, and the plate exhibited high corrosion resistance in a CASS (copper-accelerated acetic acid salt spray) test.

Abstract. This study investigated the dynamics of pollination of Lantana fucata Lindley by Parides ascanius Cramer in the restinga place of Environmental Protection Area of Grumari, located in western Rio de Janeiro. The study was conducted from january to december 2009, recording the flowering period, the number of open flowers per day and data on morphology, color and odor of flowers. The occurrence of floral visitors was recorded throughout the day, observing the time of visit and conduct intra-floral played. The flowers of L. fucata are organized into chapters and have diurnal anthesis, starting at 6 am and ending as 5 pm. The flowers are 1.0 cm in length, are colored purple, tubular and exude odor mild and pleasant. The species has a continuous flowering and has floral attributes typical of psicophily (pollination by butterflies. Butterflies observed visiting flowers of L. fucata were Mechanitis polymnia Bates, P. ascanius and Mimoides lysithous harrisianus Swainson. Of these, P. ascanius stood out as effective pollinator because of the attendance of visits to flowers during the whole year. This study highlights the mutualistic relationship between L. fucata and P. ascanius established between the supply of nectar as a food resource to the butterfly, while this is responsible for pollinating the flowers and the formation of fruits and seeds.

Monolayer II-VI semiconductors: A first-principles prediction

Science.gov (United States)

Zheng, Hui; Chen, Nian-Ke; Zhang, S. B.; Li, Xian-Bin

A systematic study of 32 honeycomb monolayer II-VI semiconductors is carried out by first-principles methods. It appears that BeO, MgO, CaO, ZnO, CdO, CaS, SrS, SrSe, BaTe, and HgTe honeycomb monolayers have a good dynamic stability which is revealed by phonon calculations. In addition, from the molecular dynamic (MD) simulation of other unstable candidates, we also find two extra monolayers dynamically stable, which are tetragonal BaS and orthorhombic HgS. The honeycomb monolayers exist in form of either a planar perfect honeycomb or a low-buckled 2D layer, all of which possess a band gap and most of them are in the ultraviolet region. Interestingly, the dynamically stable SrSe has a gap near visible light, and displays exotic electronic properties with a flat top of the valence band, and hence has a strong spin polarization upon hole doping. The honeycomb HgTe has been reported to achieve a topological nontrivial phase under appropriate in-plane tensile strain and spin-orbital coupling (SOC). Some II-VI partners with less than 5% lattice mismatch may be used to design novel 2D heterojunction devices. If synthesized, potential applications of these 2D II-VI families could include optoelectronics, spintronics, and strong correlated electronics.

Representations of race and skin tone in medical textbook imagery.

2018-04-01

Although a large literature has documented racial inequities in health care delivery, there continues to be debate about the potential sources of these inequities. Preliminary research suggests that racial inequities are embedded in the curricular edification of physicians and patients. We investigate this hypothesis by considering whether the race and skin tone depicted in images in textbooks assigned at top medical schools reflects the diversity of the U.S. We analyzed 4146 images from Atlas of Human Anatomy, Bates' Guide to Physical Examination & History Taking, Clinically Oriented Anatomy, and Gray's Anatomy for Students by coding race (White, Black, and Person of Color) and skin tone (light, medium, and dark) at the textbook, chapter, and topic level. While the textbooks approximate the racial distribution of the U.S. population - 62.5% White, 20.4% Black, and 17.0% Person of Color - the skin tones represented - 74.5% light, 21% medium, and 4.5% dark - overrepresent light skin tone and underrepresent dark skin tone. There is also an absence of skin tone diversity at the chapter and topic level. Even though medical texts often have overall proportional racial representation this is not the case for skin tone. Furthermore, racial minorities are still often absent at the topic level. These omissions may provide one route through which bias enters medical treatment. Copyright © 2018.

Ovine leather has around half the tear strength of bovine leather and is therefore not suitable for high-value applications such as shoes. Tear strength has been correlated with the natural collagen fibril alignment (orientation index, OI). It is hypothesized that it could be possible to artificially increase the OI of the collagen fibrils and that an artificial increase in OI could increase tear strength. Ovine skins, after pickling and bating, were strained biaxially during chrome tanning. The strain ranged from 2 to 15% of the initial sample length, either uniformly in both directions by 10% or with 3% in one direction and 15% in the other. Once tanned, the leather tear strengths were measured and the collagen fibril orientation was measured using synchrotron-based small-angle X-ray scattering. The OI increased as a result of strain during tanning from 0.48 to 0.79 (P = 0.001) measured edge-on and the thickness-normalized tear strength increased from 27 to 43 N mm -1 (P leather was strained 10% in two orthogonal directions. This is evidence to support a causal relationship between high OI (measured edge-on), highly influenced by thickness, and tear strength. It also provides a method to produce stronger leather. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Lattice thermal transport in group II-alloyed PbTe

2018-04-01

PbTe, one of the most promising thermoelectric materials, has recently demonstrated a thermoelectric figure of merit (ZT) of above 2.0 when alloyed with group II elements. The improvements are due mainly to significant reduction of lattice thermal conductivity (κl), which was in turn attributed to nanoparticle precipitates. However, a fundamental understanding of various phonon scattering mechanisms within the bulk alloy is still lacking. In this work, we apply the newly-developed density-functional-theory-based compressive sensing lattice dynamics approach to model lattice heat transport in PbTe, MTe, and Pb0.94M0.06Te (M = Mg, Ca, Sr, and Ba) and compare our results with experimental measurements, with focus on the strain effect and mass disorder scattering. We find that (1) CaTe, SrTe, and BaTe in the rock-salt structure exhibit much higher κl than PbTe, while MgTe in the same structure shows anomalously low κl; (2) lattice heat transport of PbTe is extremely sensitive to static strain induced by alloying atoms in solid solution form; (3) mass disorder scattering plays a major role in reducing κl for Mg/Ca/Sr-alloyed PbTe through strongly suppressing the lifetimes of intermediate- and high-frequency phonons, while for Ba-alloyed PbTe, precipitated nanoparticles are also important.

Detection of fissionable materials in cargoes using monochromatic photon radiography

2015-04-01

The detection of Special Nuclear Materials (e.g. Pu and U) and nuclear devices in the commercial cargo traffic is one of the challenges posed by the threat of nuclear terrorism. Radiography and active interrogation of heavily loaded cargoes require ~ 1 - 10MeV photons for penetration. In a proof-of-concept system under development at MIT, the interrogating monochromatic photon beam is produced via a 11B(d , nγ) 12C reaction. To achieve this, a boron target is used along with the 3 MeV d+ RFQ accelerator at MIT-Bates. The reactions results in the emission of very narrow 4.4 MeV and 15.1 MeV gammas lines. The photons, after traversing the cargo, are detected by an array of NaI(Tl) detectors. A spectral analysis of the transmitted gammas allows to independently determine the areal density and the atomic number (Z) of the cargo. The proposed approach could revolutionize cargo inspection, which, in its current fielded form has to rely on simple but high dose bremsstrahlung sources. Use of monochromatic sources would significantly reduce the necessary dose and allow for better determination of the cargo's atomic number. The general methodology will be described and the preliminary results from the proof-of-concept system will be presented and discussed.

Method Participants were 82 preschool-age children who stutter (CWS) and 120 who do not stutter (CWNS). Correlation-based statistics (Bates, Appelbaum, Salcedo, Saygin, & Pizzamiglio, 2003) identified dissociations across 5 norm-based speech-language subtests. The Behavioral Style Questionnaire Distractibility subscale measured attentional distractibility. Analyses addressed (a) between-groups differences in the number of children exhibiting speech-language dissociations; (b) between-groups distractibility differences; (c) the relation between distractibility and speech-language dissociations; and (d) whether interactions between distractibility and dissociations predicted the frequency of total, stuttered, and nonstuttered disfluencies. Results More preschool-age CWS exhibited speech-language dissociations compared with CWNS, and more boys exhibited dissociations compared with girls. In addition, male CWS were less distractible than female CWS and female CWNS. For CWS, but not CWNS, less distractibility (i.e., greater attention) was associated with more speech-language dissociations. Last, interactions between distractibility and dissociations did not predict speech disfluencies in CWS or CWNS. Conclusions The present findings suggest that for preschool-age CWS, attentional processes are associated with speech-language dissociations. Future investigations are warranted to better understand the directionality of effect of this association (e.g., inefficient attentional processes → speech-language dissociations vs. inefficient attentional processes ← speech-language dissociations).

Differential cross sections to discrete final states have been measured for both positive and negative pion photo-production on 13 C at 90 0 in the lab at pion energies of 18, 29, and 41 MeV. Measurements were made using a fixed angle magnetic spectrometer located in the 14 0 area of the MIT Bates linear accelerator. Pions were detected using a 90 channel multi-wire proportional counter in the focal plane along with a backup array consisting of three 1/16'' thick plastic scintillator detectors and a 1/2'' thick Cerenkov detector. Positive pion photo-production cross sections were obtained for the excitation of the 3/2 - ground state and for the 3.45 MeV first excited state of 13 B. Negative pion photo-production cross sections were obtained for the excitation of the 1/2 - ground state, and the 3/2 to 3.51 MeV and 5/2 to 7.39 MeV excited states of 13 N. The measured positive pion photo-production ground state cross sections are in reasonable agreement wth theoretical calculations. However, there is a large discrepancy between the measured negative pion photoproduction ground state cross sections and the theoretical values. There are no theoretical calculations available for comparison with the excited state measurements in either positive or negative pion photoproduction on 13 C

In early 1979 a group of physicists assembled at the University of Virginia (UVa) for a conference entitled ''Future Possibilities for Electron Accelerators.'' In the audience sat an organizer of the conference, UVa professor James McCarthy. While listening to talks by Gregory Loew of the Stanford Linear Accelerator Center (SLAC) and Roger Servranckx of the University of Saskatchewan, McCarthy got very excited. Both discussed new approaches to producing an almost continuous stream of electrons with improved designs for pulse stretcher rings that could be built within a reasonable budget. McCarthy saw the possibility of realizing a dream. This dream had its origins in the 1950s, when Robert Hofstadter, McCarthy's thesis advisor, made groundbreaking discoveries at Stanford's High Energy Physics Laboratory (HEPL) about the internal structure of nuclei and nucleons. For these experiments Hofstadter used Mark III, the most advanced in a series of electron accelerators designed by William Hansen, who pioneered methods of high frequency acceleration of electrons. The work by Hofstadter and Hansen led to two productive lines of inquiry. One group of researchers studied particle production using electrons at higher energies, which led to the construction in the 1960s of SLAC at Stanford. Another group of researchers, which included McCarthy, investigated nuclear structure with more modest increases in energy accompanied by increases in the duty factor of the electron beam. This line of inquiry, electro-nuclear physics, led in the 1960s and 1970s to a succession of accelerators, including a $7.2 million high duty factor 400 MeV linear accelerator (linac) completed in 1972 at the Bates Laboratory at the Massachusetts Institute of Technology (Bates-MIT), and ambitious attempts to develop untried technologies to further boost energy and duty factor, most notably the effort to develop superconducting radiofrequency (srf) accelerating technology at HEPL.

model showed a 0.51 median Fit (intersection of simulated and observed areas divided by the union of the two, Bates and De Roo, 2000) and a 0.74 maximum. Obviously, this approach is quite rough, and would require testing on events of homogeneous return periods (which is not the case for now). The next steps in the test and the development of our method include the use of the AIGA distributed model to simulate past-events hydrographs, the search for a new way to automatically approach bankfull flow and the integration of the results in our model to build dynamic maps of the flood.

Purpose: We present the results from a clinical trial of accelerated partial breast irradiation (APBI), using mixed modulated photon and electron beams (MERT+IMRT) with the same photon multileaf collimator (xMLC). Methods: Seven patients were enrolled in the first year of the APBI clinical trial. Patients were selected following the conditions included in the NSABP B-39/RTOG 0413 protocol. The targets and clinically relevant normal structures were contoured on the CT images following this protocol for APBI-EBRT. All treatments were delivered using combined modulated electron and photon beams by means of the same xMLC installed in a SIEMENS Primus linac, with a reduced SSD equal to 60 cm for electron beams. The plans were performed with a treatment planning system based on full Monte Carlo simulations, called CARMEN, developed by our group. Simultaneously, an alternative IMRT plan was calculated with the commercial TPS PINNACLE v8.0m (Philips), and both plans were compared. An ad-hoc breast phantom with semi-spherical geometry called NAOMI was designed for a specific QA protocol. Patients received a total dose of 38.5 Gy, delivered in 10 fractions over 5 consecutive days, with a twice-a-day hypofractionated schema.Follow-up visits during 2.5 years on average were repeated at 1 month post-treatment, every 3 months for the first year, and every 6 months for the second year. Toxicity was scored according to National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE version 3.0). Results: This APBI technique achieved high loco-regional control rates and showed low acute toxicity (grade 1 of CTCAE) and no toxicities from first month onwards. Photographic assessment of cosmesis showed skin excellent results. Conclusion: The clinical results achieved with MERT+IMRT by using the same xMLC are comparable or even better than those obtained with other APBI techniques, thanks to a software solution without any additional equipment or specific device.

Speaking of Freedom: U.S. Multicultural Literature and Human Rights Talk In an Emerging Democracy

In February 2013, I served as the first US Fulbright scholar in a Myanmar public university in almost thirty years. Our discipline was chosen for this venture because, according to the project overview, “American literature is not a sensitive subject with the Ministry of Education and thus a good idea.” Knowing it to be risky, I introduced Masters students and their faculty to recent US literature, focusing primarily on works by women and minorities beginning with the Civil Rights movement. My texts were selected from those I teach in my course on US women writers at home, but in Myanmar, they were discussed with predominantly female groups representing the many religious and ethnic groups within Myanmar.  On other occasions, I met with women from NGOs or participated in programs on Women’s Studies and issues such as human trafficking. The experience yielded multiple opportunities to reflect and theorize about the nature of global rights and reciprocity; I was able to compare how women in Myanmar and the US responded to concerns relevant to marginalized populations, even as I confronted issues arising from post-colonialism and male privilege daily.  Yet the most intriguing parts of the experience were the silences, evasions, and hesitations which constantly interrupted conversations about the opportunities for improving civil rights in the shift toward democracy.  Slowly, we were able to use literature to draw implicit parallels and open conversations about “sensitive topics” so that in the end, the experience was transformative for all of us. Adapting a line from a Naomi Shihab Nye poem, one of my students wrote, “Until you speak Myanmar, you will not understand freedom.” And she was right. My presentation will analyze how US multicultural women’s literature provided scaffolding for more extensive conversations about women and human rights, drawing on literary theory and student narratives as appropriate.

It is generally assumed that children with Down syndrome (DS) present a deficit in lexical production relative to their cognitive abilities. However, the literature on this topic has recently shown several contradictory results. In addition, most studies only consider vocabulary production in its vocal modality. However it is also necessary to take into account gesture production, since this is a strength in children with DS. Our main purpose in this study, therefore, was to investigate the relationship between cognitive development and vocabulary size in both its vocal and gestural modalities in a broad sample of Spanish children with DS. Participants in the study were 66 children with DS and 66 children with typical development (TD), with a mental age (MA) of 14-28 months (divided into five groups with a MA of 14-16, 17-19, 20-22, 23-25 and 26-28 months). Children were matched on the basis of their gender and MA. Productive vocabularies were collected using an adaptation of the MacArthur-Bates CDI for children with DS. In vocal modality, the number of words produced by children with DS and children with TD is similar. As in previous studies, our data confirmed that gestural communication is superior in children with DS. However, when words and gestures are combined, the performance of both groups of children is practically equal. Our results do not support a specific dissociation between cognitive and lexical development in children with DS.

A Study of the Temperature Distribution in UO{sub 2} Reactor Fuel Elements

Energy Technology Data Exchange (ETDEWEB)

Devold, I

1968-05-15

Thermal conductivity is one of the most important properties of nuclear reactor fuels. Accurate knowledge of this property is vital because, among other things, it determines the maximum power that can be taken out of the fuel element per unit length of the material without exceeding the safety limits of the fuel elements. This report consists of a study of the thermal behaviour of uranium dioxide in the form of reactor fuel. The experimental part of the report describes measurements performed at the OECD Halden Reactor Project, Halden, Norway. The experiment was originally set up in order to measure the temperature at the center of a UO{sub 2} fuel element as a function of element power, in order to determine the safe operation limit of the fuel assembly. However, in analysing the data obtained, very interesting thermal conductivity values were obtained and comparison with existing correlations could be performed. This comparison shows that a certain agreement is obtained between the measured data at Halden and a theory published by J.L. Bates in 1961, which predicts an increase in the thermal conductivity above 1500 deg C. The data obtained below 1300 deg C are also in good agreement with measurements performed by Vogt, Grandell and Runfors in 1964. The report contains a mathematical description of the heat transfer mechanisms in cylindrical fuel elements. The model is coded in FORTRAN IV-code and referred to as FUELTEMP.

The possession game? A comparative analysis of ball retention and team success in European and international football, 2007-2010.

Collet, Christian

2013-01-01

Possession is thought of as central to success in modern football, but questions remain about its impact on positive team outcomes (Bate, 1988; Hughes & Franks, 2005; Pollard & Reep, 1997; Stanhope, 2001). Recent studies (e.g. Bloomfield, Polman, & O'Donoghue, 2005; Carling, Williams, & Reilly, 2005; James, Mellallieu, & Holley, 2002; Jones, James, & Mellalieu, 2004; Lago, 2009; Lago & Martin, 2007; Lago-Peñas & Dellal, 2010; Lago-Peñas, Lago-Ballesteros, Dellal, & Gómez, 2010; Taylor, Mellalieu, & James, 2005; Tucker, Mellalieu, James, & Taylor, 2005) that have examined these questions have often been constrained by an exclusive focus on English or Spanish domestic play. Using data from five European leagues, UEFA and FIFA tournaments, the study found that while possession time and passing predicted aggregated team success in domestic league play, both variables were poor predictors at the individual match level once team quality and home advantage were accounted for. In league play, the effect of greater possession was consistently negative; in the Champions League, it had virtually no impact. In national team tournaments, possession failed to reach significance when offensive factors were accounted for. Much of the success behind the 'possession game' was thus a function of elite teams confined in geographic and competitive space. That ball hegemony was not consistently tied to success suggests that a nuanced approach to possession is needed to account for variant strategic environments (e.g. James et al., 2002) and compels match analysts to re-examine the metric's overall value.

Since around 1723, on the occasion of its initial colonization by Europeans, Rondonia has received successive waves of immigrants. This has been further swelled by individuals from northeastern Brazil, who began entering at the beginning of the twentieth century. The ethnic composition varies across the state according to the various sites of settlement of each wave of immigrants. We analyzed the frequency of the CCR5Δ32 allele of the CCR5 chemokine receptor, which is considered a Caucasian marker, in five sample sets from the population. Four were collected in Porto Velho, the state capital and the site of several waves of migration. Of these, two, from the Hospital de Base were comprised of HB Mothers and HB Newborns presenting allele frequencies of 3.5% and 3.1%, respectively, a third from the peri-urban neighborhoods of Candelária/Bate-Estaca (1.8%), whereas a fourth, from the Research Center on Tropical Medicine/CEPEM (0.6%), was composed of malaria patients under treament. The fifth sample (3.4%) came from the inland Quilombola village of Pedras Negras. Two homozygous individuals (CCR5Δ32/CCR5Δ32) were detected among the HB Mother samples. The frequency of this allele was heterogeneous and higher where the European inflow was more pronounced. The presence of the allele in Pedras Negras revealed European miscegenation in a community largely comprising Quilombolas. PMID:22481870

NEW ECO-EFFICIENT PRODUCTS USED IN LEATHER INDUSTRY

ROSU Dan

2016-05-01

Full Text Available In today's move to "sustainable production" the leather industry, as well as many other industries is recognized as a polluting one. Traditional chemical operations are polluting because of the levels of inorganic chemical waste. Process chemicals which are not consumed within the reactions necessary to convert collagen to leather are currently discharged to waste. These are usually applied during bulk production, such as inorganic agents from beam house and tanning processes, e.g. lime, sulphide, ammonium salts, sulphuric acid and sodium chloride, mineral tanning agents – mainly Cr(III and the less common Al(III, Zr(III, Ti(III, Fe(III salts -, whereas depending on the tanning process and the leather article produced organic chemical waste discharged comprises aldehydic and polyphenolic tanning products, bating enzymes, organic carboxylic acids and excess electrolyte stable synthetic fat liquors. It is rare for chemicals and water to be recovered for re-use from several of these process steps. Moreover, tanners worldwide are required to operate within strict legislative boundaries. Serious drawbacks continuously arise concerning the chrome–tanning process in leather industry and the environmental hazardous consequences of chromium containing effluents. In order to overcome this impediment, a great deal of research has been focused on developing chrome–free tanning methods in the past years, such as titanium tanning. In the present study, Ti–Al tanned bovine leather was characterized by means of SEM microscopy, EDAX elemental analysis, ATR–FTIR spectroscopy, thermogravimetry TGA, and differential scanning calorimetry DSC techniques.

Full Text Available Introduction. The aim of this paper is to deal with the information seeking and use problem in a professional context and understand how activity can influence practices, by taking as examples, the research undertaken by economic analysts. We analyse the relationship between the situational approach, described by Cheuk, the work environment complexity (with social, technological and personal aspects, and the information seeking and use strategies, which relied on Ellis and Wilson's model, with Bates's comments. Method. We interviewed eight economists, using a questionnaire and the SICIA (Situation, Complexity and Information Activity method. The SICAI method is a qualitative approach, which underlines the relationship between situations, professional contexts and strategies. Both methods allow better understanding of how investment analysts find out what they need for their job. We can clarify their information sources and practices of information seeking, which are very particular because of their activities. We complete our analysis by interviewing analysts from financial institutions. Analysis. A qualitative mode of analysis was used to interpret the interviewees' comments, within the research framework adopted. Results. We find similarity in information seeking and use strategies used by these two groups and environmental levels meet in most situations. But some differences can be also found, explained by the activity frameworks and goals. Conclusion. This study demonstrates that the activity and also the professional context (here the financial context can directly influence practices.

Organizarea teritorială a spațiului rural în contextul reformei administrative

Full Text Available The undertaking of a territorial and administra-tive reform is one of the main topics in both public and scientifc debate these years. The political de-bate is focused on some specifc issues such as: how many regions Romania must have, which cities should be the centers of those regions or what kind of institutions should be created. From this point of view, this paper presents a new perspective about the process of regionalization. The goal of this paper is to analyze the theoretical and empirical bases of the actual system of the rural localities. In Romania there are more than 2800 rural localities, but only a small part of them have the f-nancial strength to sustain the development policiesby their own. The vast majority of the communes are dependent upon the public allocations. On one hand, the most developed rural localities, situated with predilection in peripheral areas of important urban centers have important competitive advan-tages relying on the size of the population and the specifcity of the economic activities. On the other hand, communes from poor areas have a signifcant defcit of public utilities and infrastructure caused by the absence of fnancial resources. Therefore, the coordinates of the local budget of revenues and expenditures represents the main determinant in the process of development of the communes. This paper argues that a serious analysis of the regiona-lization process should take into account the reform of the actual rural administrative system.

A Study of the Temperature Distribution in UO2 Reactor Fuel Elements

International Nuclear Information System (INIS)

Devold, I.

1968-05-01

Thermal conductivity is one of the most important properties of nuclear reactor fuels. Accurate knowledge of this property is vital because, among other things, it determines the maximum power that can be taken out of the fuel element per unit length of the material without exceeding the safety limits of the fuel elements. This report consists of a study of the thermal behaviour of uranium dioxide in the form of reactor fuel. The experimental part of the report describes measurements performed at the OECD Halden Reactor Project, Halden, Norway. The experiment was originally set up in order to measure the temperature at the center of a UO 2 fuel element as a function of element power, in order to determine the safe operation limit of the fuel assembly. However, in analysing the data obtained, very interesting thermal conductivity values were obtained and comparison with existing correlations could be performed. This comparison shows that a certain agreement is obtained between the measured data at Halden and a theory published by J.L. Bates in 1961, which predicts an increase in the thermal conductivity above 1500 deg C. The data obtained below 1300 deg C are also in good agreement with measurements performed by Vogt, Grandell and Runfors in 1964. The report contains a mathematical description of the heat transfer mechanisms in cylindrical fuel elements. The model is coded in FORTRAN IV-code and referred to as FUELTEMP

Developmental approaches to autism treatment aim to establish strong interpersonal relationships through joint play. These approaches have emerging empirical support; however, there is a need for further research documenting the procedures and demonstrating their effectiveness. This pilot study evaluated changes in parent behavior and child autism symptoms following a 12-week Developmental Reciprocity Treatment parent-training program. A total of 22 children with autism spectrum disorder between 2 and 6 years (mean age = 44.6 months, standard deviation = 12.7) and a primary caregiver participated in 12 weekly sessions of Developmental Reciprocity Treatment parent training, covering topics including introduction to developmental approaches, supporting attention and motivation, sensory regulation and sensory-social routines, imitation/building nonverbal communication, functional language development, and turn taking. Results indicated improvement in aspects of parent empowerment and social quality of life. Improvement in core autism symptoms was observed on the Social Responsiveness Scale total score (F(1,19): 5.550, p = 0.029), MacArthur-Bates Communicative Development Inventories number of words produced out of 680 (F(1,18): 18.104, p = 0.000), and two subscales of the Repetitive Behavior Scale, Revised (compulsive, p = 0.046 and restricted, p = 0.025). No differences in sensory sensitivity were observed on the Short Sensory Profile. Findings from this pilot study indicate that Developmental Reciprocity Treatment shows promise and suggest the need for future controlled trials of this developmentally based intervention.

Measurements of electron scattering from 18 O were performed at the MIT-Bates Linear Accelerator Center at 110 degrees and 140 degrees, at momentum transfers ranging from about 1.2 to 2.5 fm -1 . Form factors were extracted for 57 discrete states with excitation energies up to about 25 MeV. The lowest 4 + states at 3.55 and 7.12 MeV are excited strongly and their form factors are well determined from prior measurements. The state at 3.65 MeV has a large (1d 5/2 )2 2p-0h component while the state at 7.12 MeV has a large 4p-2h component with the we ampersand k-coupling configuration, 20 Ne(4 + )direct-product 14 C(0 + ). New form-factor measurements will be presented for normal-parity states at 8.96 MeV and 11.67 MeV. The state at 8.96 MeV is identified as the 4 + state with a large (1d 5/2 )(ld 3/2 ) 2p-0h component, and the state at 11.67 MeV is identified as the 4 + state belonging to a K π = 2 + rotational band having large 4p-2h components and headed by a 2 + state at 9.38 MeV. New measurements for the state at 9.36 MeV will be presented as well

and its breaching such as depth, wide, length, volume and breaching shape and daily total rainfall data were used in the models. The simulated flooding in the both models were compared with the real flood extent which gathered from photos taken after the flood event, high satellite images acquired after 20 days from the flood event, and field works. The results show that LISFLOOD-Roe hydraulic model gives more than 80% fit to the extent of real flood event. Also both modelling results show that the embankment breaching of the Ata Pond directly affected the flood magnitude and intensity on the area. This study reveals that modelling of the probable flooding in urban areas is necessary and very important in urban planning. References Gallegos, H. A., Schubert, J. E., and Sanders, B.

El objetivo de este estudio fue determinar la presencia o ausencia de estas virosis en poblaciones de langostinos silvestres (Pleoticus muelleri en el estuario de Bahía Blanca, aplicando metodologías bioquímicas, de biología molecular y genéticas. Los resultados demuestran que se ha logrado optimizar la metodología para la extracción y purificación de ADN y ARN de tejido y hemolinfa de langostinos y el correcto manejo en la captura, acondicionamiento y transporte de los animales al laboratorio. Los ensayos fueron debidamente convalidados por reacciones de control negativas y positivas. En las muestras estudiadas de Pleoticus muelleri se descarta la presencia de estas tres enfermedades virales. Esta metodología permite no sólo realizar una detección temprana y un diagnóstico de las tres patologías virales sino también establecer y asegurar un status libre de infección con el consiguiente beneficio sanitario para la región.Trade in aquatic animals calls for the implementation of controls for the detection of pathogenic viruses in line with the regulations of the OIE, the World Organization for Animal Heath. In relation specifically to trade in crustaceans, the OIE identifies the following diseases: White Spot syndrome virus disease (WSSV; Yellow Head Virus disease (YHV; and Taura syndrome virus disease (TSV, all of which are highly dangerous. The purpose of this study was to determine whether these viruses occur in wild populations of Pleoticus muelleri in Bahía Blanca estuary, Argentina, using biochemical, molecular biology and genetics methods. The results show that the methods used for DNA and RNA extraction and purification from the tissue and hemolymph of these crustaceans, and the techniques for their capture, packaging and transportation to the laboratory have been optimized. Tests were properly validated by negative and positive controls. None of the named diseases were found in the wild populations of Pleoticus muelleri. The methodology followed in the present research not only enables early detection and diagnosis of the three viral pathologies but also ensures an infection-free status with the concomitant health benefits for the region.

Parameterizing correlations between hydrometeor species in mixed-phase Arctic clouds

Larson, Vincent E.; Nielsen, Brandon J.; Fan, Jiwen; Ovchinnikov, Mikhail

2011-01-01

Mixed-phase Arctic clouds, like other clouds, contain small-scale variability in hydrometeor fields, such as cloud water or snow mixing ratio. This variability may be worth parameterizing in coarse-resolution numerical models. In particular, for modeling multispecies processes such as accretion and aggregation, it would be useful to parameterize subgrid correlations among hydrometeor species. However, one difficulty is that there exist many hydrometeor species and many microphysical processes, leading to complexity and computational expense. Existing lower and upper bounds on linear correlation coefficients are too loose to serve directly as a method to predict subgrid correlations. Therefore, this paper proposes an alternative method that begins with the spherical parameterization framework of Pinheiro and Bates (1996), which expresses the correlation matrix in terms of its Cholesky factorization. The values of the elements of the Cholesky matrix are populated here using a "cSigma" parameterization that we introduce based on the aforementioned bounds on correlations. The method has three advantages: (1) the computational expense is tolerable; (2) the correlations are, by construction, guaranteed to be consistent with each other; and (3) the methodology is fairly general and hence may be applicable to other problems. The method is tested noninteractively using simulations of three Arctic mixed-phase cloud cases from two field experiments: the Indirect and Semi-Direct Aerosol Campaign and the Mixed-Phase Arctic Cloud Experiment. Benchmark simulations are performed using a large-eddy simulation (LES) model that includes a bin microphysical scheme. The correlations estimated by the new method satisfactorily approximate the correlations produced by the LES.

This progress report refers to the period August 1993 to September 1994, which includes the second year of the three year period December 1, 1992--November 30, 1995 of our existing research contract. The budget proposal for the third year, December 1, 1994 to November 30, 1995 as originally approved, is also presented. As anticipated in our 1992--1995 proposal, Fermilab E760/E835 on high precision charmonium spectroscopy has remained a major part of our preoccupation and commitment during the last year, and it will remain so in the forthcoming year. In early 1994 we joined the collaboration of the Brookhaven experiment E852 on the spectroscopy of states with exotic quantum numbers. The first successful three month run of E852 was completed on July 31 and preliminary data analysis has been started. Some new commitments have resulted from this collaboration and a separate proposal for supplemental financial support is being prepared for them. At Los Alamos our experiment number-sign 1274 on search of extremely neutron rich exotic nuclei by pion absorption began making initial measurements a month ago and is expected to take data during the period October 15--November 30, 1994. In addition to the above on-going programs, our Bates proposal (94-01) for a definitive measurement of the quenching of the longitudinal response in quasi-free scattering of electrons from nuclei has been approved with high priority for 600 hours of beam time, and we expect to start the experiment in late 1995

Development of a computational algorithm for the linearization of decay and transmutation chains; Desarrollo de un algoritmo computacional para la linealizacion de cadenas de decaimiento y transmutacion

One of the most used methodologies to solve Bate man equations, in the problem of burning, is the Tta (Transmutation Trajectory Analysis) method. In this method, a network of decays is broken down into linear elements known as trajectories, through a process known as linearization. In this work an alternative algorithm is shown to find and construct these trajectories, which considers three aspects of linearization: the information -a priori- about the elements that make up decay and transmutation network, the use of a new notation, and in the functions for the treatment of text strings (which are common in most programming languages). One of the main advantages of the algorithm is that can condense the information of a decay and transmutation network into only two vectors. From these is possible to determine how many linear chains can be extracted from the network and even their length (in the case they are not cyclical). Unlike the Deep First Search method, which is widely used for the linearization process, the method proposed in the present work does not have a backward routine and instead occupies a process of compilation, since completes fragments chain instead of going back to the beginning of the trajectories. The developed algorithm can be applied in a general way to the information search and to the linearization of the computational data structures known as trees. It can also be applied to engineering problems where one seeks to calculate the concentration of some substance as a function of time, starting from linear differential equations of balance.

Accuracy of phonetic transcription is a core skill for speech and language therapists (SLTs) worldwide (Howard & Heselwood, 2002). The current study investigates the value of weekly independent online phonetic transcription tasks to support development of this skill in year one SLT students. Using a mixed methods observational design, students enrolled in a year one phonetics module completed 10 weekly homework activities in phonetic transcription on a stand-alone tutorial site (WebFon (Bates, Matthews & Eagles, 2010)) and 5 weekly online quizzes (the 'Ulster Set' (Titterington, unpublished)). Student engagement with WebFon was measured in terms of the number of responses made to 'sparks' on the University's Virtual Learning Environment Discussion Board. Measures of phonetic transcription accuracy were obtained for the 'Ulster Set' and for a stand-alone piece of coursework at the end of the module. Qualitative feedback about experience with the online learning was gathered via questionnaire. A positive significant association was found between student engagement with WebFon and performance in the 'Ulster Set', and between performance in the 'Ulster Set' and final coursework. Students valued both online independent learning resources as each supported different learning needs. However, student compliance with WebFon was significantly lower than with the 'Ulster Set'. Motivators and inhibitors to engagement with the online resources were investigated identifying what best maximised engagement. These results indicate that while 'independent' online learning can support development of phonetic transcription skills, the activities must be carefully managed and constructively aligned to assessment providing the level of valance necessary to ensure effective engagement.

Two different methods for retrieving Upper Tropospheric Humidities (UTH) from the TOVS (TIROS Operational Vertical Sounder) instruments aboard NOAA polar orbiting satellites are presented and compared. The first one, from the Environmental Technology Laboratory, computed by J. Bates and D. Jackson (hereafter BJ method), estimates UTH from a simplified radiative transfer analysis of the upper tropospheric infrared water vapor channel at wavelength measured by HIRS (6.3 micrometer). The second one results from a neural network analysis of the TOVS (HIRS and MSU) data developed at, the Laboratoire de Meteorologie Dynamique (hereafter the 3I (Improved Initialization Inversion) method). Although the two methods give very similar retrievals in temperate regions (30-60 N and S), an absolute bias up to 16% appears in the convective zone of the tropics. The two datasets have also been compared with UTH retrievals from infrared radiance measurements in the 6.3 micrometer channel from the geostationary satellite METEOSAT (hereafter MET method). The METEOSAT retrievals are systematically drier than the TOVS-based results by an absolute bias between 5 and 25%. Despite the biases, the spatial and temporal correlations are very good. The purpose of this study is to explain the deviations observed between the three datasets. The sensitivity of UTH to air temperature and humidity profiles is analysed as are the clouds effects. Overall, the comparison of the three retrievals gives an assessment of the current uncertainties in water vapor amounts in the upper troposphere as determined from NOAA and METEOSAT satellites.

The University of Massachusetts (UMass) Nuclear Physics Program continues to concentrate upon the use of the electromagnetic interaction in a joint experimental and theoretical approach to the study of nucleon and nuclear properties. During the past year the activities of the group involved data analysis, design and construction of equipment, planning for new experiments, completion of papers and review articles for publication, writing of proposals for experiments, but very little actual data acquisition. Section II.A. described experiments at Bates Linear Accelerator Center. They include the following: electrodisintegration of deuteron; measurement of the elastic magnetic form factor of 3 He; coincidence measurement of the D(e,e'p) cross section; transverse form factors of 117 Sn; ground state magnetization density of 89 Y; and measurement of the 5th structure function in deuterium and 12 C. Section II.B. includes the following experiments at Stanford Linear Accelerator Center: deuteron threshold electrodisintegration; separation of charge and magnetic form factors of the neutron and proton; measurement of the X-, Q 2 , and A-dependence of R = σ L /σ T ; and analysis of 14.5 GeV electrons and positions scattered from gases in the PEP Storage Ring. Section III.C. includes the following experiments at NIKHEF and Lund: complementary studies of single-nucleon knockout and single-nucleon wave functions using electromagnetic interactions and single-particle densities of sd-shell nuclei. Section II.D. discusses preparations for future work at CEBAF: electronics for the CLAS region 1 drift chamber Section III. includes theoretical work on parity-violating electron scattering and nuclear structure

To see whether action and object processing across different tasks and modalities differs in brain-injured speakers of Chinese with varying fluency and lesion locations within the left hemisphere. Words and pictures representing actions and objects were presented to a group of 33 participants whose native and/or dominant language was Mandarin Chinese: 23 patients with left-hemisphere lesions due to stroke and 10 language-, age- and education-matched healthy control participants. A set of 120 stimulus items was presented to each participant in three different forms: as black and white line drawings (for picture-naming), as written words (for reading) and as aurally presented words (for word repetition). Patients were divided into groups for two separate analyses: Analysis 1 divided and compared patients based on fluency (Fluent vs. Nonfluent) and Analysis 2 compared patients based on lesion location (Anterior vs. Posterior). Both analyses yielded similar results: Fluent, Nonfluent, Anterior, and Posterior patients all produced significantly more errors when processing action (M = 0.73, SD = 0.45) relative to object (M = 0.79, SD = 0.41) stimuli, and this effect was strongest in the picture-naming task. As in our previous study with English-speaking participants using the same experimental design (Arévalo et al., 2007, Arévalo, Moineau, Saygin, Ludy, & Bates, 2005), we did not find evidence for a double-dissociation in action and object processing between groups with different lesion and fluency profiles. These combined data bring us closer to a more informed view of action/object processing in the brain in both healthy and brain-injured individuals.

Permanent childhood hearing impairment often results in speech and language problems that are already apparent in early childhood. Past studies show a clear link between language skills and the child's social-emotional functioning. The aim of this study was to examine the level of language and communication skills after the introduction of early identification services and their relation with social functioning and behavioral problems in deaf and hard of hearing children. Nationwide cross-sectional observation of a cohort of 85 early identified deaf and hard of hearing preschool children (aged 30-66 months). Parents reported on their child's communicative abilities (MacArthur-Bates Communicative Development Inventory III), social functioning and appearance of behavioral problems (Strengths and Difficulties Questionnaire). Receptive and expressive language skills were measured using the Reynell Developmental Language Scale and the Schlichting Expressive Language Test, derived from the child's medical records. Language and communicative abilities of early identified deaf and hard of hearing children are not on a par with hearing peers. Compared to normative scores from hearing children, parents of deaf and hard of hearing children reported lower social functioning and more behavioral problems. Higher communicative abilities were related to better social functioning and less behavioral problems. No relation was found between the degree of hearing loss, age at amplification, uni- or bilateral amplification, mode of communication and social functioning and behavioral problems. These results suggest that improving the communicative abilities of deaf and hard of hearing children could improve their social-emotional functioning. Copyright © 2015 Elsevier Ireland Ltd.

Study of rare gas plasmas seeded with an alkaline substance

Energy Technology Data Exchange (ETDEWEB)

Darrigo, R

1974-12-31

Thesis. The transfer properties of a mixture of inert gases and potassium suitable for use in magnetohydrodynamic generators were determined. Hypotheses were put forward in order to define the interaction potential between two atoms of potassium. The transfer properties were subsequently evaluated. New experimental results have since been obtained. Special attention is given to those of Ivanovskii et al. which give the self-diffusion coefficient for potassium and the diffusion coefficient for helium-potassium. The results obtained differ by no more than 1% from those presented. The hypotheses put forward are thus valid and it is assumed that the transfer properties obtained for the complex mixture are realistic. Nevertheless, the properties connected with thermodiffusion necessitate supplementary verification. The interpretation of the preliminary experimental results in terms of the strengths of the Heierman oscillator led to the identification of a disequilibrium between the temperatures of the heavy and light species. In addition, the transfer properties were calculated for different values of the disequilibrium coefficient. New values are suggested for the oscillator strengths of the principal and diffuse series of potassium from experimental results obtained using two different installations, i.e., a helium-argon-potassium mixture and a flame seeded with potassium carbonate. In order to study recombination, a boundary layer was produced by circulating the plasma near to an externally cooled wall. The determination of the recombination coefficient in the central core yields results similar to those of Bates. This is not true, however, for the boundary layer. The excessively large values obtained in this case suggest the existence of a disequilibrium. (FR)

The effects of Communicative functions and Mind-Mindedness on children's language development have been typically investigated in separate studies. The present longitudinal research was therefore designed to yield new insight into the simultaneous impact of these two dimensions of maternal responsiveness on the acquisition of expressive language skills in a sample of 25 mother-child dyads. The frequencies of five communicative functions (Tutorial, Didactic, Conversational, Control and Asynchronous) and two types of mind-related comments (attuned vs. non-attuned) were assessed from a 15-min play session at 16 months. Children's expressive language was examined at both 16 months (number of word types and tokens produced, and number of words attributed to the child in the Questionnaire for Communication and Early Language development) and 20 months (number of internal and non-internal words attributed to the child in the Italian version of the Mac Arthur-Bates Communicative Development Inventory). The main finding was that mothers' use of attuned mind-related comments at 16 months predicted internal state language at 20 months, above and beyond the effects of CFs and children's linguistic ability at 16 months; in addition, mothers' Tutorial function at 16 months marginally predicted non-internal state language at 20 months, after controlling for MM and children's linguistic ability at 16 months. These results suggest that different expressions of maternal responsiveness influence distinct aspects of children's expressive language in the second year of life, although the effects of MM appear to be more robust.

Analytic approaches to atomic response properties

International Nuclear Information System (INIS)

Lamm, E.E.

1980-01-01

Many important response properties, e.g., multipole polarizabilites and sum rules, photodetachment cross sections, and closely-related long-range dispersion force coefficients, are insensitive to details of electronic structure. In this investigation, analytic asymptotic theories of atomic response properties are constructed that yield results as accurate as those obtained by more elaborate numerical methods. In the first chapter, a novel and simple method is used to determined the multipole sum rules S/sub l/(-k), for positive and negative values of k, of the hydrogen atom and the hydrogen negative ion in the asymptotic approximation. In the second chapter, an analytically-tractable extended asymptotic model for the response properites of weakly-bound anions is proposed and the multipole polarizability, multipole sum rules, and photodetachment cross section determined by the model are computed analytically. Dipole polarizabilities and photodetachment cross sections determined from the model for Li-, Na-, and K- are compared with the numercal results of Moores and Norcross. Agreement is typically within 15% if the pseudopotential is included. In the third chapter a comprehensive and unified treatment of atomic multipole oscillator strengths, dynamic multipole polarizabilites, and dispersion force constants in a variety of Coulomb-like approximations is presented. A theoretically and computationally superior modification of the original Bates-Damgaard (BD) procedure, referred to here as simply the Coulomb approximation (CA), is introduced. An analytic expression for the dynamic multipole polarizability is found which contains as special cases this quantity within the CA, the extended Coulomb approximation (ECA) of Adelman and Szabo, and the quantum defect orbital (QDO) method of Simons

The wound condition determined the type of dressings used and the dressing change frequency. A total of 62 participants with diabetic foot ulcers (70 wounds) were divided into two groups: non-macerated (n = 52) and macerated wounds (n = 18). Each group was evaluated weekly using the Bates-Jensen Wound Assessment Tool, with follow-ups until week 4. The Mann-Whitney U test showed that the changes in the wound area in week 1 were faster in the non-macerated group than the macerated group (P = 0·02). The Pearson correlation analysis showed a moderate correlation between maceration and wound healing from enrolment until week 4 (P = 0·002). After week 4, the Kaplan-Meier analysis showed that the non-macerated wounds healed significantly faster than the macerated wounds (log-rank test = 19·378, P = 0·000). The Cox regression analysis confirmed that maceration was a significant and independent predictor of wound healing in this study (adjusted hazard ratio, 0·324; 95% CI, 0·131-0·799; P = 0·014). The results of this study demonstrated that there is a relationship between maceration and wound healing. Changes in the wound area can help predict the healing of wounds with maceration in clinical settings. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Aloe vera is a medicinal plant that has been traditionally used to accelerate wound healing. Olive oil is also a natural product that may contribute to wound healing owing to its antimicrobial and anti-inflammatory effects. The present study aimed to evaluate the effect of an Aloe vera-olive oil (AVO) combination cream on the healing process of chronic wounds. In this randomised, double-blind, comparator-controlled, parallel-group trial, patients with chronic wounds were treated with either AVO cream or phenytoin cream as the standard treatment for a period of 30 days. Wound healing was evaluated using Bates-Jensen assessment tool and the severity of pain was assessed using a visual analogue scale (VAS). After initial assessment, 60 patients with chronic wounds (41 with pressure ulcer, 13 with diabetic wounds and 6 with venous ulcers), were recruited and randomised into 2 groups of 30. After 30 days of treatment, significant improvements in the wound size, depth, and edges; necrotic tissue type and amount; exudate type and amount; colour of wound surroundings; and peripheral tissue oedema score were observed in the AVO cream group (p<0.001). The total score of wound healing showed significant improvement with both AVO (p<0.001) and phenytoin (p<0.01) creams, although AVO was more efficacious (p<0.001). Likewise, although both treatments reduced the initial VAS score, the efficacy of AVO was significantly greater (p<0.001). AVO cream significantly accelerates biological healing of chronic wounds and helps to reduce pain severity with a higher efficacy compared with phenytoin cream.

Development of a computational algorithm for the linearization of decay and transmutation chains

One of the most used methodologies to solve Bate man equations, in the problem of burning, is the Tta (Transmutation Trajectory Analysis) method. In this method, a network of decays is broken down into linear elements known as trajectories, through a process known as linearization. In this work an alternative algorithm is shown to find and construct these trajectories, which considers three aspects of linearization: the information -a priori- about the elements that make up decay and transmutation network, the use of a new notation, and in the functions for the treatment of text strings (which are common in most programming languages). One of the main advantages of the algorithm is that can condense the information of a decay and transmutation network into only two vectors. From these is possible to determine how many linear chains can be extracted from the network and even their length (in the case they are not cyclical). Unlike the Deep First Search method, which is widely used for the linearization process, the method proposed in the present work does not have a backward routine and instead occupies a process of compilation, since completes fragments chain instead of going back to the beginning of the trajectories. The developed algorithm can be applied in a general way to the information search and to the linearization of the computational data structures known as trees. It can also be applied to engineering problems where one seeks to calculate the concentration of some substance as a function of time, starting from linear differential equations of balance.

Maine and its industries identified more efficient utilization of biomass as a critical economic development issue. In Phase I of this implementation project, a research team was assembled, research equipment was implemented and expertise was demonstrated in pyrolysis, hydrodeoxygenation of pyrolysis oils, catalyst synthesis and characterization, and reaction engineering. Phase II built upon the infrastructure to innovate reaction pathways and process engineering, and integrate new approaches for fuels and chemical production within pulp and paper and other industries within the state. This research cluster brought together chemists, engineers, physicists and students from the University of Maine, Bates College, and Bowdoin College. The project developed collaborations with Oak Ridge National Laboratory and Brookhaven National Laboratory. The specific research projects within this proposal were of critical interest to the DoE - in particular the biomass program within EERE and the catalysis/chemical transformations program within BES. Scientific and Technical Merit highlights of this project included: (1) synthesis and physical characterization of novel size-selective catalyst/supports using engineered mesoporous (1-10 nm diameter pores) materials, (2) advances in fundamental knowledge of novel support/ metal catalyst systems tailored for pyrolysis oil upgrading, (3) a microcalorimetric sensing technique, (4) improved methods for pyrolysis oil characterization, (5) production and characterization of woody biomass-derived pyrolysis oils, (6) development of two new patented bio oil pathways: thermal deoxygenation (TDO) and formate assisted pyrolysis (FASP), and (7) technoeconomics of pyrolysis of Maine forest biomass. This research cluster has provided fundamental knowledge to enable and assess pathways to thermally convert biomass to hydrocarbon fuels and chemicals.

This work describes the first in-flight absolute calibration of the "Sistema Satelital para la Observación de la Tierra" (SSOT or Fasat-C). It was performed on January 29th 2013 at Antumapu site located in the southern area of Santiago, Chile. A description of the procedure is presented which includes both ground measurement and atmospheric characterization. The Chilean satellite for Earth observation carries on board a "New AstroSat Optical Modular Instrument" (NAOMI) high-resolution pushbroom imager which provides a 1.45 m ground sampling distance in the panchromatic (0.455-0.744 μm) channel and a 5.8 m ground sampling distance for the green (0.455-0.52 μm), blue (0.528-0.588 μm), red (0.625-0.695 μm) and near-infrared (0.758-0.881 μm) channels from a 620 km orbit. Radiometric calibration was carried out in order to estimate the land leaving radiance and bidirectional reflectance at the top of the atmosphere. To correct the reflectance data for atmospheric effects, the Second Simulation of a Satellite Signal in the Solar Spectrum (6S) code was used. Aerosol Optical Depth (AOD), water vapor and ozone content were obtained from MOD04, MOD05 and MOD07 products respectively, which are derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) data. Statistical results such as BIAS, SIGMA and RMSE were calculated for the comparison between surface reflectance values and in situ measurements. Results show that the overall accuracy of the atmospherically corrected surface reflectance calculated from Fasat-C imagery can be estimated to around ±5%, with a R2 coefficient of 0.939 between atmospherically corrected reflectance values and in situ measurements. The atmospheric correction applied in this work by combining MODIS data and the 6S radiative transfer code could be used for further calibration of the Fasat-C images, although in situ atmospheric irradiance measurements are necessary to estimate reliable values of surface reflectance.

surprising (and disappointing) since (a) all of these authors are experienced teachers of physical chemistry and thermodynamics, and (b) most readers of this Journal would suppose that the nature of the Gibbs function and the manner in which it is to be used are issues that have been settled long ago, and that there are no disagreements of any significance between practitioners of thermodynamics regarding these matters. Historical Background. The beginning of the controversy was occasioned by a paper of Schomaker and Waser (1), in which they dealt with an ancient problem going back to Bates. This problem is by now variously described as the "Ether Problem", or the "Bates Problem", or the "Bates-Tykodi Problem". It considers the change occurring when a two-phase system of liquid (e.g., ether) and its vapor, coexisting at equilibrium at a given temperature, is allowed to expand into a larger space (originally evacuated), with a final state consisting of the liquid and vapor still at equilibrium at the same temperature, but now occupying a larger volume (with the volumes of the liquid and vapor phases being smaller and larger, respectively, than in the original state). Since the initial and final states of the ether are both two-phase liquid/vapor systems at the same temperature and pressure, then of course deltaG = 0 for the ether itself; but how should the spontaneous nature of this process be expressed thermodynamically? Schomaker and Waser showed straightforwardly that when the ether and its surroundings are considered together, then deltaS > q/T as required by the Second Law. They further showed that deltaA Schomaker and Waser took things a step further and by so doing initiated the discussion and controversy that eventually led to the following four papers. In this step they took as the thermodynamic system of interest not just the ether but the ether together with the entire container that separates it from the surrounding constant-temperature, constant-pressure fluid

Language development is often slower in preterm children compared with their term peers. We investigated factors associated with vocabulary acquisition at 2 years in a cohort of children born at 28 weeks' gestation or less. For children entered into the United Kingdom Oscillation Study, language development was evaluated by using the MacArthur-Bates Communicative Development Inventories score, completed by parents as part of a developmental questionnaire. The effect of demographic, neonatal, socioeconomic factors, growth, and disability were investigated using multifactorial random effects modelling. Questionnaires were returned by 288 participants (148 males, 140 females). The mean number of words vocalized was 42 (SD 29). Multifactorial analysis showed only four factors were significantly associated with vocabulary acquisition. These were: (1) level of disability (mean words: no disability, 45; other disability, 38; severe disability, 30 [severe disability is defined as at least one extreme response in one of the following clinical domains: neuromotor, vision, hearing, communication, or other physical disabilities]; 95% confidence interval [CI] for the difference between no and severe disability 7- 23); (2) sex (39 males, 44 females; 95% CI 0.4-11); (3) length of hospital stay (lower quartile, 47; upper quartile, 38; 95% CI -12 to -4); and (4) weight SD score at 12 months (lower quartile, 39; upper quartile, 44; 95% CI 1-9). There was no significant association between gestational age and vocabulary after multifactorial analysis. There was no significant effect of any socioeconomic factor on vocabulary acquisition. We conclude that clinical factors, particularly indicators of severe morbidity, dominate the correlates of vocabulary acquisition at age 2 in children born very preterm.

The conceptual basis of mathematics in cardiology: (I) algebra, functions and graphs.

This is the first in a series of four articles developed for the readers of. Without language ideas cannot be articulated. What may not be so immediately obvious is that they cannot be formulated either. One of the essential languages of cardiology is mathematics. Unfortunately, medical education does not emphasize, and in fact, often neglects empowering physicians to think mathematically. Reference to statistics, conditional probability, multicompartmental modeling, algebra, calculus and transforms is common but often without provision of genuine conceptual understanding. At the University of Vermont College of Medicine, Professor Bates developed a course designed to address these deficiencies. The course covered mathematical principles pertinent to clinical cardiovascular and pulmonary medicine and research. It focused on fundamental concepts to facilitate formulation and grasp of ideas. This series of four articles was developed to make the material available for a wider audience. The articles will be published sequentially in Coronary Artery Disease. Beginning with fundamental axioms and basic algebraic manipulations they address algebra, function and graph theory, real and complex numbers, calculus and differential equations, mathematical modeling, linear system theory and integral transforms and statistical theory. The principles and concepts they address provide the foundation needed for in-depth study of any of these topics. Perhaps of even more importance, they should empower cardiologists and cardiovascular researchers to utilize the language of mathematics in assessing the phenomena of immediate pertinence to diagnosis, pathophysiology and therapeutics. The presentations are interposed with queries (by Coronary Artery Disease, abbreviated as CAD) simulating the nature of interactions that occurred during the course itself. Each article concludes with one or more examples illustrating application of the concepts covered to cardiovascular medicine and

Full Text Available ntroduction & Objective: Leishmania is a protozoan of the trypanosomatidae family. This pro-tozoan has two stages in its life cycle, promastigote form in sand flies and amastigote form in macrophage of mammalian hosts. The purpose of this study was identification and compari-son of proteins of Leishmania amastigote and promastigote stages. Materials & Methods: The present study is a cross sectional study of two forms of Leishmania major. To culture promastigotes , L.major (MRHO/IR/75/ER from previously infected Balb/c mice was transferred to modified N.N.N medium with overlay of liquid BHI and then transferred to RPMI-1640 at 26oc ± 1 for mass production. After isolation and growth, pro-mastigotes were transferred to liquid cell culture medium RPMI-1640 with pH 5.5 and incu-bated at 5% CO2 at 37oc for 72 hours until promastigote to amastigote transformation. Elec-trophoresis was performed with SDS-PAGE method to find and compare the molecular weight of the antigens of two stages. Results: The molecular weights of the bands observed in both forms were as follows: 19, 36, 50, 63, 65, 80, 90, 94, 96, 110- 130 KDa. The proteins in the surface of only promastigote were 22, 28 and 46 KDa and special proteins in the surface of amastigote were 12 and 32 KDa. Conclusion : According to this study Leishmania parasite has stage specific proteins. Various studies have shown that axenic amastigotes and tissue amastigotes are similar in their protein content. Therefore, based on stage specific proteins ,effective drugs and vaccines can be de-signed against leishmaniasis. (Sci J Hamadan Univ Med Sci 2013; 20 (1:1-8

This progress report and continuation proposal summarizes our achievements for the period from July 1, 1994 to September 30, 1995 and requests continued funding for our program in experimental medium-energy nuclear physics. The focus of our program remains the understanding of the short-range part of the strong interaction in the nuclear medium. In the past year we have focused our attention ever more sharply on experiments with real tagged photons, and we have successfully defended two new experimental proposals: Photofission of Actinide and Preactinide Nuclei at SAL and Photoproduction of the ρ Meson from the Proton with Linearly Polarized Photons at CEBAF. (We are co-spokespersons on two previously approved Hall-B experiments at CEBAF, Photoreactions on 3 He and Photoabsorption and Photofission of Nuclei.) As part of the team that is instrumenting the Photon Tagger for Hall B; we report excellent progress on the focal-plane detector array that is being built at our Nuclear Detector Laboratory, as well as progress on our plans for instrumentation of a tagged polarized-photon beam using coherent bremsstrahlung. Also, we shall soon receive a large computer system (from the SSC) which will form the basis for our new Data Analysis Center, which, like the Nuclear Detector Laboratory, will be operated under the auspices of The George Washington University Center for Nuclear Studies. Finally, during the past year we have published six more papers on the results of our measurements of pion scattering at LAMPF and of electron scattering at NIKHEF and Bates, and we can report that nearly all of the remaining papers documenting this long series of measurements are in the pipeline

Full Text Available Introduction: Salinity is one of the most important environmental factors that regulates plant growth and development, and limits plant production. Researchers have shown that some plant growth regulators such as nitric oxide improve the plants resistance to environmental stresses such as heat, cold, drought and salinity. Sodium nitroprusside (SNP commonly has been used as nitric oxide (NO donor in plants. NO is a diffusible gaseous free radical. Low concentrations of NO inhibit the production of reactive oxygen species and protect plants against ROS damages. The aim of this study was to evaluate the role of SNP as NO donor on salt tolerance of Calendula officinalis and its effects on some morphological, physiological and biochemical characteristics of this plant. Materials and Methods: In this study, the effects of salinity (0, 25, 50, 75 and 100 mM and sodium nitroprusside (0.0, 0.25, 0.50 and 0.75 mM on morphological and physiological characteristics of Calendula officinalis L. were investigated. Total leaf area and number of leaves were determined in the end of the experiment. Electrolyte leakage was used to asses’ membrane permeability. This procedure was based on Lutts et al.,1995. Soluble sugars were extracted and estimated by the method of Irigoyen et al., 1992. Chlorophyll a, b and carotenoid content were calculated from the absorbance of extract at 653, 666 and 470 nm using the formula of Dere et al., 1998. Proline was extracted by the method of Bates et al., 1973. DPPH radical- scavenging activity of sample was performed as described previously of Cleep et al., 2012. The SAS software was used for the analysis of variance (ANOVA, comparisons with P

ENGLISH ABSTRACT: Manufacturing companies operate in a business environment where incremental growth may be achieved through expansion and renewal of existing plant and facilities. Effective management of the critical success factors of such capital development projects may also provide competitive advantage. These projects tend to be of a brown-field nature, characterised by a significant level of risk arising from the interaction between the project implementation and concurrent operation of the existing physical asset base. So it is vital to understand the factors that influence the success of capital expansion and renewal projects in the brown-field context. Although each project has unique features, there are critical success factors that can be customised for successful outcomes in the brown-field environment. This study identifies five critical success factors applicable to brown-field capital expansion and renewal projects. Managerial focus on the critical factors, and the prospects for successful brown-field projects, are discussed in the paper.

The hypothesis that anthropogenic sulfur aerosol influences clear-sky and cloud albedo and can thus influence climate has been advanced by several investigators; current global-average climate forcing is estimated to be of comparable magnitude, but opposite sign, to longwave forcing by anthropogenic greenhouse gases. The high space and time variability of sulfate concentrations and column aerosol burdens have been established by observational data; however, geographic and time coverage provided by data from surface monitoring networks is very limited. Consistent regional and global estimates of sulfate aerosol loading, and the contributions to this loading from different sources can be obtained only by modeling studies. Here we describe a sub-hemispheric to global-scale Eulerian transport and transformation model for atmospheric sulfate and its precursors, driven by operational meteorological data, and report results of calculations for October, 1986 for the North Atlantic and adjacent continental regions. The model, which is based on the Global Chemistry Model uses meteorological data from the 6-hour forecast model of the European Center for Medium-Range Weather Forecast to calculate transport and transformation of sulfur emissions. Time- and location-dependent dry deposition velocities were estimated using the methodology of Wesely and colleagues. Chemical reactions includes gaseous oxidation of SO 2 and DMS by OH, and aqueous oxidation of SO 2 by H 2 O 2 and O 3 . Anthropogenic emissions were from the NAPAP and EMEP 1985 inventories and biogenic emissions based on Bates et al. Calculated sulfate concentrations and column burdens exhibit high variability on spatial scale of hundreds of km and temporal scale of days. Calculated daily average sulfate concentrations closely reproduce observed concentrations at locations widespread over the model domain

This study examined the contribution of cognitive function, severity of autism, and adaptive functioning to the variability in language and communication skills in 129 preschool children (aged 24-63 months) with autism spectrum disorder (ASD). Participants were selected from a representative research cohort of 208 preschool children on the basis of caregiver completion of the MacArthur-Bates Communicative Development Inventories (CDI). The children were classified into three cognitive groups: (a) Normal intelligence; (b) Developmental delay; and (c) Intellectual disability. Autism symptom severity was measured by the Autistic Behavior Checklist (ABC), and adaptive functioning by the Daily Living Skills (DLS) and Socialization (Soc) subscales from the Vineland Adaptive Behavior Scales. For each of five CDI variables (Phrases understood, Words understood, Words produced, Gestures and actions, and Language use), the contribution of cognition, severity of autism symptoms, and adaptive functioning to the variability was examined. Cognition and age explained about half or more of the variance in the four verbal language CDI variables, but only about one fourth of the variance in the non-verbal communication variable Gestures and actions. Severity of autism symptoms and the two adaptive measures (DLS and Soc) each only accounted for a few percent more of the variance in the four CDI language variables; however, for Gestures and actions, an additional 11-21% of the variance was accounted for. In conclusion, for children with ASD, receptive and expressive language is mainly related to cognitive level, whereas non-verbal communication skills seem to also be related to severity of autism symptoms and adaptive functioning.

The detection of assembled nuclear devices and concealed special nuclear materials (SNM) such as plutonium or uranium in commercial cargo traffic is a major challenge in mitigating the threat of nuclear terrorism. Currently available radiographic and active interrogation systems use ∼1-10 MeV bremsstrahlung photon beams. Although simple to build and operate, bremsstrahlung-based systems deliver high radiation doses to the cargo and to potential stowaways. To eliminate problematic issues of high dose, we are developing a novel technique known as multiple monoenergetic gamma radiography (MMGR). MMGR uses ion-induced nuclear reactions to produce two monoenergetic gammas for dual-energy radiography. This allows us to image the areal density and effective atomic number (Zeff) of scanned cargo. We present initial results from the proof-of-concept experiment, which was conducted at the MIT Bates Research and Engineering Center. The purpose of the experiment was to assess the capabilities of MMGR to measure areal density and Zeff of container cargo mockups. The experiment used a 3.0 MeV radiofrequency quadrupole accelerator to create sources of 4.44 MeV and 15.11 MeV gammas from the 11B(d,nγ)12C reaction in a thick natural boron target; the gammas are detected by an array of NaI(Tl) detectors after transmission through cargo mockups . The measured fluxes of transmitted 4.44 MeV and 15.11 MeV gammas were used to assess the areal density and Zeff. Initial results show that MMGR is capable of discriminating the presence of high-Z materials concealed in up to 30 cm of iron shielding from low- and mid-Z materials present in the cargo mockup.

Voluntary Management of Residential Water Demand in Low and Middle-Low Income Households: Case Study of Soacha (colombia)

Acosta, R.; Rodriguez, J. P.

2016-12-01

Water resources availability is a global concern due to increasing demands, decreasing quality and uncertain spatio-temporal variability (United Nations, 2009). In urban contexts research on efficient water use is a priority to cope with the future vulnerability of water supplies as a result of the impacts of climate change (Bates et al, 2008). Following the proposed methodologies of He and Kua (2013) for implementing programs to promote sustainable energy consumption, we focused on the use of educational strategies to promote a voluntary rationalization of residential water demand. We collaborated with three schools in Soacha (Colombia) where students ranging from 12 to 15 years participated in the project as promoters of educational campaigns inside their families, covering 120 low and middle-low income households. Three intervention or treatment strategies (i.e. e-learning, in-person active learning activities and graphical learning tools) were carried out over a period of 5 months. We analyzed the effects of the treatments strategies in reducing water consumption rates and the dependence of this variable on socio-demographic, economic, environmental, and life quality factors by using personal interviews and self reported water saving technics. The results showed that educational campaigns have a positive effect on reducing consumption in the households. Graphical learning tools accounted for the highest reduction in water consumption. Moreover, the results of the study suggests that socio-economic factors such as type of house, social level, income, and life quality variables significantly affect the variability in water consumption, which is an important fact to consider in similar cases where communities face difficult socio-economic conditions, displacement or high rates of urban growth.

The nucleon-nucleon interaction in the presence of the electromagnetic field: Nucleon-nucleon bremsstrahlung

International Nuclear Information System (INIS)

Brown, V.R.

1990-01-01

Nucleon-nucleon bremsstrahlung, NNγ, is a fundamental process, which involves the strong and electromagnetic fields acting simultaneously. Since the electromagnetic interaction is well known, NNγ provides a calculable tool for comparing off-energy-shell effects from different two-nucleon potentials compared to experiment and also provides a simple testing ground, which is sensitive to meson-exchange-current contributions that are so important in electronuclear physics. Historically, experimental studies have focused on ppγ, with only a few measurements of npγ. The present workshop was organized primarily to investigate the interest in, the value of, and the feasibility of doing an npγ experiment using the neutron white source at LANL. An increasing amount of US nuclear physics dollars are being spent on electronuclear physics. npγ is a fundamental process with large meson-exchange currents. In the npγ calculations of Brown and Franklin, the meson-exchange contributions increase the cross section by a factor of roughly two and later the angular distribution of the emitted photon dramatically. The details of these calculated effects have never been verified experimentally, but the proper quantum-mechanical inclusion of meson-exchange contributions, using the methods of brown and Franklin, has proved to be essential in understanding the heavy-ion results. The understanding of the importance of such terms is extremely important inelectronuclear processes, such as are presently under investigation or being planned at Bates, SLAC, and CEBAF. Just one example is in the electrodisintegration of the deuteron, where meson-exchange contributions must be included properly before any conclusions about nuclear models, such as QCD versus meson-exchange potentials can be made

Multiple Landslide-Hazard Scenarios Modeled for the Oakland-Berkeley Area, Northern California

With the exception of Los Angeles, perhaps no urban area in the United States is more at risk from landsliding, triggered by either precipitation or earthquake, than the San Francisco Bay region of northern California. By January each year, seasonal winter storms usually bring moisture levels of San Francisco Bay region hillsides to the point of saturation, after which additional heavy rainfall may induce landslides of various types and levels of severity.

Social conversational skills are a salient aspect of early pragmatic development in young children. These skills include two different abilities, assertiveness and responsiveness. This study investigated the development of these abilities in early implanted children and their relationships with lexical development and some language-sensitive variables. Prospective, observational, nonrandomized study. Participants included 28 children with congenital profound sensorineural hearing loss. The mean age at device activation was 13.3 months (standard deviation [SD] ±4.2). The Social-Conversational Skills Rating Scale was used to evaluate assertiveness and responsiveness. The MacArthur-Bates Communicative Development Inventory (Words and Sentences form) was used to analyze the lexical development. The device experience was 12 months for each child, and the mean age at testing was 25.9 months (SD ±4.6). Assertiveness and responsiveness scores were within the normal range of normal-hearing age-matched peers. Age at cochlear implant activation exerted a significant impact, with the highest scores associated to the youngest patients. The residual correlations between assertiveness and responsiveness with the lexical development were positive and strongly significant (r = 0.69 and 0.73, respectively). Preoperative hearing threshold demonstrated an associated significant coefficient on the assertiveness score. Age at diagnosis and maternal education level were not correlated with the social conversational skills. Early-implanted children developed social conversational skills that are similar to normal-hearing peers matched for age 1 year after device activation. Social conversational skills and lexical development were strongly correlated, but the present study design cannot specify the direction of this relationship. Children with better preoperative residual hearing exhibited better assertive ability. 4 Laryngoscope, 126:2098-2105, 2016. © 2015 The American Laryngological

Compact Polarimetry in a Low Frequency Spaceborne Context

2011-01-01

Compact polarimetry has been shown to be an interesting alternative mode to full polarimetry when global coverage and revisit time are key issues. It consists on transmitting a single polarization, while receiving on two. Several critical points have been identified, one being the Faraday rotation (FR) correction and the other the calibration. When a low frequency electromagnetic wave travels through the ionosphere, it undergoes a rotation of the polarization plane about the radar line of sight for a linearly polarized wave, and a simple phase shift for a circularly polarized wave. In a low frequency radar, the only possible choice of the transmit polarization is the circular one, in order to guaranty that the scattering element on the ground is illuminated with a constant polarization independently of the ionosphere state. This will allow meaningful time series analysis, interferometry as long as the Faraday rotation effect is corrected for the return path. In full-polarimetric (FP) mode, two techniques allow to estimate the FR: Freeman method using linearly polarized data, and Bickel and Bates theory based on the transformation of the measured scattering matrix to a circular basis. In CP mode, an alternate procedure is presented which relies on the bare surface scattering properties. These bare surfaces are selected by the conformity coefficient, invariant with FR. This coefficient is compared to other published classifications to show its potential in distinguishing three different scattering types: surface, doublebounce and volume. The performances of the bare surfaces selection and FR estimation are evaluated on PALSAR and airborne data. Once the bare surfaces are selected and Faraday angle estimated over them, the correction can be applied over the whole scene. The algorithm is compared with both FP techniques. In the last part of the paper, the calibration of a CP system from the point of view of classical matrix transformation methods in polarimetry is

The contract work was initiated by J. Epstein. The emphasis of the proposal was on (a) the continuation of DWIA calculations of the (γ,π +- ) reaction in the Δ(1232) region with the extension to the (γ,π 0 ) reaction and (b) the application of the DWIA approach to the (γ,K) reaction. The (γ,π 0 ) work was intended to be in close collaboration with the experimental studies underway at Bates Linear Accelerator and the (γ,K +- ) calculations are relevant to proposed high duty factor electron accelerators in the 1 to 4 GeV region. DWIA calculations were carried out for coherent (γ,π 0 ) reactions in 12 C. Although the DWIA approach seems less fundamental than the current Δ-hole model calculations, we had hopes that it could be more readily applicable to incoherent reactions leaving the target nucleus in the excited state. Epstein hoped to improve the reliability of the DWIA calculations for coherent (γ,π 0 ) production by better treatment of the Δ propagating in the nuclear medium. In parallel with the (γ,π 0 ) work, Epstein carried on an active collaboration with William Donnelly on the (γ,K +- ) problem. They had succeeded in a relatively complete description of the reaction for 12 C, and were beginning to extend the results to heavy nuclei, when Epstein abruptly resigned his academic post at Boston University (in August 1983) and took an industrial position. Justus Koch of NIKEF, working together with Donnelly, and assisted by modest per diem funds from this grant, the γ,K +- calculations were carried forward. A copy of the talk by Donnelly entitled Photo- and Electron-Production of Kaons and the Study of Hypernuclei given October 29, 1984 at Bad Honnef, Germany is enclosed. The talk covers the results of the work initiated by Epstein and Donnelly, and completed by Koch and Donnelly

The clinical basis of orthorexia nervosa: emerging perspectives

Full Text Available Nancy S Koven, Alexandra W Abry Department of Psychology, Bates College, Lewiston, ME, USA Abstract: Orthorexia nervosa describes a pathological obsession with proper nutrition that is characterized by a restrictive diet, ritualized patterns of eating, and rigid avoidance of foods believed to be unhealthy or impure. Although prompted by a desire to achieve optimum health, orthorexia may lead to nutritional deficiencies, medical complications, and poor quality of life. Despite its being a distinct behavioral pattern that is frequently observed by clinicians, orthorexia has received very little empirical attention and is not yet formally recognized as a psychiatric disorder. In this review, we synthesize existing research to identify what is known about the symptoms, prevalence, neuropsychological profile, and treatment of orthorexia. An examination of diagnostic boundaries reveals important points of symptom overlap between orthorexia and anorexia nervosa, obsessive–compulsive disorder (OCD, obsessive–compulsive personality disorder (OCPD, somatic symptom disorder, illness anxiety disorder, and psychotic spectrum disorders. Neuropsychological data suggest that orthorexic symptoms are independently associated with key facets of executive dysfunction for which some of these conditions already overlap. Discussion of cognitive weaknesses in set-shifting, external attention, and working memory highlights the value of continued research to identify intermediate, transdiagnostic endophenotypes for insight into the neuropathogenesis of orthorexia. An evaluation of current orthorexia measures indicates a need for further psychometric development to ensure that subsequent research has access to reliable and valid assessment tools. Optimized assessment will not only permit a clearer understanding of prevalence rates, psychosocial risk factors, and comorbid psychopathology but will also be needed to index intervention effectiveness.

Phthalates are a group of chemicals found in a variety of consumer products. They have anti-androgenic properties and human studies have reported associations between prenatal phthalate exposure and neuropsychological development in the offspring despite different cognitive tests, different ages and varying timing of exposure. To investigate the association between prenatal phthalate exposure and language development in children aged 20-36months. In the Odense Child Cohort, we analyzed 3rd trimester urine samples of 518 pregnant women for content of metabolites of diethyl, di-n-butyl, diisobutyl, butylbenzyl, di(2-ethylhexyl), and diisononyl phthalate, adjusted for osmolality. Language development was addressed using the Danish version of the MacArthur-Bates Communicative Development Inventories "Words and Sentences". Associations were assessed using logistic regression models comparing children below and above the 15th percentile while stratifying by sex and adjusting for maternal age and educational level. Phthalate metabolites were detectable in all samples although in lower levels than previous studies. Among boys, increased prenatal phthalate exposure was associated with lower scores in language development; odds ratios for vocabulary score below the 15th percentile with doubling in monoethyl phthalate, and summed di-(2-ethylhexyl) phthalate metabolites were respectively 1.24 (95% confidence interval: 1.05,1.46), and 1.33 (1.01,1.75). Similar associations were found for language complexity. No associations were found for girls. Our findings are notable, as adverse associations were suggested even in this low-level exposed population, with only one spot urine sample for exposure assessment and control for confounders. Lower scores in early language development are of relevance to health as this test predicts later educational success. Copyright © 2017. Published by Elsevier Inc.

Evidence for large-magnitude, post-Eocene extension in the northern Shoshone Range, Nevada, and its implications for Carlin-type gold deposits in the lower plate of the Roberts Mountains allochthon

The northern Shoshone and Toiyabe Ranges in north-central Nevada expose numerous areas of mineralized Paleozoic rock, including major Carlin-type gold deposits at Pipeline and Cortez. Paleozoic rocks in these areas were previously interpreted to have undergone negligible postmineralization extension and tilting, but here we present new data that suggest major post-Eocene extension along west-dipping normal faults. Tertiary rocks in the northern Shoshone Range crop out in two W-NW–trending belts that locally overlie and intrude highly deformed Lower Paleozoic rocks of the Roberts Mountains allochthon. Tertiary exposures in the more extensive, northern belt were interpreted as subvertical breccia pipes (intrusions), but new field data indicate that these “pipes” consist of a 35.8 Ma densely welded dacitic ash flow tuff (informally named the tuff of Mount Lewis) interbedded with sandstones and coarse volcaniclastic deposits. Both tuff and sedimentary rocks strike N-S and dip 30° to 70° E; the steeply dipping compaction foliation in the tuffs was interpreted as subvertical flow foliation in breccia pipes. The southern belt along Mill Creek, previously mapped as undivided welded tuff, includes the tuff of Cove mine (34.4 Ma) and unit B of the Bates Mountain Tuff (30.6 Ma). These tuffs dip 30° to 50° east, suggesting that their west-dipping contacts with underlying Paleozoic rocks (previously mapped as depositional) are normal faults. Tertiary rocks in both belts were deposited on Paleozoic basement and none appear to be breccia pipes. We infer that their present east tilt is due to extension on west-dipping normal faults. Some of these faults may be the northern strands of middle Miocene (ca. 16 Ma) faults that cut and tilted the 34.0 Ma Caetano caldera ~40° east in the central Shoshone Range (

This study aims to test whether a weighted combination of several hydrological models can simulate flows more accurately than the models taken individually. In addition, the project attempts to identify the most efficient model averaging method and the optimal number of models to include in the weighting scheme. In order to address the first objective, streamflow was simulated using four lumped hydrological models (HSAMI, HMETS, MOHYSE and GR4J-6), each of which were calibrated with three different objective functions on 429 watersheds. The resulting 12 hydrographs (4 models × 3 metrics) were weighted and combined with the help of 9 averaging methods which are the simple arithmetic mean (SAM), Akaike information criterion (AICA), Bates-Granger (BGA), Bayes information criterion (BICA), Bayesian model averaging (BMA), Granger-Ramanathan average variant A, B and C (GRA, GRB and GRC) and the average by SCE-UA optimization (SCA). The same weights were then applied to the hydrographs in validation mode, and the Nash-Sutcliffe Efficiency metric was measured between the averaged and observed hydrographs. Statistical analyses were performed to compare the accuracy of weighted methods to that of individual models. A Kruskal-Wallis test and a multi-objective optimization algorithm were then used to identify the most efficient weighted method and the optimal number of models to integrate. Results suggest that the GRA, GRB, GRC and SCA weighted methods perform better than the individual members. Model averaging from these four methods were superior to the best of the individual members in 76% of the cases. Optimal combinations on all watersheds included at least one of each of the four hydrological models. None of the optimal combinations included all members of the ensemble of 12 hydrographs. The Granger-Ramanathan average variant C (GRC) is recommended as the best compromise between accuracy, speed of execution, and simplicity.

Owing to the number and severity of concomitant factors, pressure ulcers remain a significant problem. A retrospective study of data from adult patients with a pressure ulcer was conducted to identify factors that may affect their healing. Data from patients who were hospitalized between January 1, 2011, and December 31, 2015, in a private Turkish university hospital who had a Stage 2, Stage 3, Stage 4, or unstageable pressure ulcer that was assessed using the Bates-Jensen Wound Assessment Tool (BWAT) were abstracted. The following variables were examined: demographic characteristics (gender, age, hospital unit, duration of hospitalization), health status and disease data (vital signs, mobility, nutrition, diagnosis, chronic diseases, medication), laboratory values (albumin, hemoglobin, blood glucose), and pressure ulcer characteristics (stage, location, healing status, duration) and pressure ulcer risk status as determined by patient Braden Scale score. Seventy-eight (78) patient records were identified. Patient mean age was 70.8 ± 13.47 years, and length of hospitalization was on average 32.52 ± 27.2 days. Most ulcers (62; 79.5%) were Stage 2 and located in the sacral area (59; 75.6%). Thirty-four (34) patients (43.6%) were discharged and 44 (56.4%) died. At the time of discharge or death, 65.4% of the ulcers had not healed. Patients whose wounds were healed were significantly more likely to have higher hemoglobin and mean arterial pressure, better mobility, received oral nutrition, and discharged from the hospital than patients whose ulcers did not heal. The results suggest that these variables, including Braden Scale and BWAT scores, might be considered when developing a treatment plan of care. Additional studies examining risk factors for nonhealing pressure ulcers, including studies with large samples to facilitate multivariate analyses, are needed.

What do brain lesions tell us about theories of embodied semantics and the human mirror neuron system?

Arévalo, Analia L; Baldo, Juliana V; Dronkers, Nina F

Recent work has been mixed with respect to the notion of embodied semantics, which suggests that processing linguistic stimuli referring to motor-related concepts recruits the same sensorimotor regions of cortex involved in the execution and observation of motor acts or the objects associated with those acts. In this study, we asked whether lesions to key sensorimotor regions would preferentially impact the comprehension of stimuli associated with the use of the hand, mouth or foot. Twenty-seven patients with left-hemisphere strokes and 10 age- and education-matched controls were presented with pictures and words representing objects and actions typically associated with the use of the hand, mouth, foot or no body part at all (i.e., neutral). Picture/sound pairs were presented simultaneously, and participants were required to press a space bar only when the item pairs matched (i.e., congruent trials). We conducted two different analyses: 1) we compared task performance of patients with and without lesions in several key areas previously implicated in the putative human mirror neuron system (i.e., Brodmann areas 4/6, 1/2/3, 21 and 44/45), and 2) we conducted Voxel-based Lesion-Symptom Mapping analyses (VLSM; Bates et al., 2003) to identify additional regions associated with the processing of effector-related versus neutral stimuli. Processing of effector-related stimuli was associated with several regions across the left hemisphere, and not solely with premotor/motor or somatosensory regions. We also did not find support for a somatotopically-organized distribution of effector-specific regions. We suggest that, rather than following the strict interpretation of homuncular somatotopy for embodied semantics, these findings support theories proposing the presence of a greater motor-language network which is associated with, but not restricted to, the network responsible for action execution and observation.

Language and Recursion

Science.gov (United States)

Lowenthal, Francis

2010-11-01

This paper examines whether the recursive structure imbedded in some exercises used in the Non Verbal Communication Device (NVCD) approach is actually the factor that enables this approach to favor language acquisition and reacquisition in the case of children with cerebral lesions. For that a definition of the principle of recursion as it is used by logicians is presented. The two opposing approaches to the problem of language development are explained. For many authors such as Chomsky [1] the faculty of language is innate. This is known as the Standard Theory; the other researchers in this field, e.g. Bates and Elman [2], claim that language is entirely constructed by the young child: they thus speak of Language Acquisition. It is also shown that in both cases, a version of the principle of recursion is relevant for human language. The NVCD approach is defined and the results obtained in the domain of language while using this approach are presented: young subjects using this approach acquire a richer language structure or re-acquire such a structure in the case of cerebral lesions. Finally it is shown that exercises used in this framework imply the manipulation of recursive structures leading to regular grammars. It is thus hypothesized that language development could be favored using recursive structures with the young child. It could also be the case that the NVCD like exercises used with children lead to the elaboration of a regular language, as defined by Chomsky [3], which could be sufficient for language development but would not require full recursion. This double claim could reconcile Chomsky's approach with psychological observations made by adherents of the Language Acquisition approach, if it is confirmed by researches combining the use of NVCDs, psychometric methods and the use of Neural Networks. This paper thus suggests that a research group oriented towards this problematic should be organized.
