Radio‐opaque fecal impaction and pseudo‐occlusion in a dialyzed patient taking lanthanum carbonate
Authors: Muller Clotilde , Muller Sandrine , Sissoko Aicha , Klein Alexandre , Faller Bernadette , Chantrel Francois
Published: November 2011

Lanthanum therapy is an efficient therapy of hyperphosphoremia by chelating phosphore in the digestive tract. Lanthanum is a silvery white metallic element that belongs to group 3 of the periodic table. This drug is lightly absorbed and has low water solubility. It should be borne in mind that abdominal X‐rays of patients taking lanthanum carbonate may have a radio‐opaque appearance typical of imaging agents. This characteristic is suggested to confirm adherence of the patient by doing an abdominal X‐ray. We describe in our case a particular good compliant patient with slow digestive transit, which ends by pseudo‐occlusion.
RADIOGRAPHIC AND ULTRASONOGRAPHIC DIAGNOSIS OF STENOSING TENOSYNOVITIS OF THE ABDUCTOR POLLICIS LONGUS MUSCLE IN DOGS
Authors: Hittmair Katharina M. , Groessl Veronika , Mayrhofer Elisabeth
Published: November 2011

Stenosing tenosynovitis of the abductor pollicis longus muscle causes chronic front limb lameness in dogs. The lesion, similar to de Quervain's tenosynovitis in people, is caused by repetitive movements of the carpus. Thirty dogs with front limb lameness, painful carpal flexion, and a firm soft tissue swelling medial to the carpus were examined prospectively. Seven dogs had bilateral abductor pollicis longus tenosynovitis. Radiographs of the carpus were characterized by a deeper radiolucent medial radial sulcus and bony proliferations medial and slightly cranial to the distal radius, resulting in stenosis of the tendon sheath and subsequent tendinitis. Ultrasonographic examination of the firm soft tissue swelling medial to the carpus was characterized by an irregular hypoechoic abductor pollicis longus tendon or tendinitis in 22 of 37 dogs. Nineteen of 37 abductor pollicis longus tendon sheaths were fluid‐filled and all tendon sheaths were thickened, more hyperechoic, with small hyperechoic mineralizations embedded in the connective tissue of the abductor pollicis longus tendon sheath in 25 dogs. Enthesopathy of the abductor pollicis longus tendon was identified in seven dogs. While radiographs of stenosing tenosynovitis of the abductor pollicis longus are helpful in visualizing the deep radial sulcus and osteophytes medial to the distal radius, ultrasonography is useful to distinguish between lesions of the tendon or tendon sheath and to determine thickness and fluid content of the abductor pollicis longus tendon sheath.
An optimal Earth Trojan asteroid search strategy
Authors: Todd M. , Tanga P. , Coward D. M. , Zadnik M. G.
Published: November 2011

Trojan asteroids are minor planets that share the orbit of a planet about the Sun and librate around the L4 or L5 Lagrangian points of stability. They are important solar-system fossils because they carry information on early Solar system formation, when collisions between bodies were more frequent. Discovery and study of terrestrial planet Trojans will help constrain models for the distribution of bodies and interactions in the inner Solar system. Since the discovery of the first outer planet Trojan in 1906, several thousand Jupiter Trojans have been found. Of the terrestrial planets, there are four known Mars Trojans, and one Earth Trojan has been recently discovered. We present a new model that constrains optimal search areas, and imaging cadences for narrow and wide-field survey telescopes including the Gaia satellite for the most efficient use of telescope time to maximize the probability of detecting additional Earth Trojans.
The Emotional Intelligence, Health, and Well‐Being Nexus: What Have We Learned and What Have We Missed?
Authors: Zeidner Moshe , Matthews Gerald , Roberts Richard D.
Published: November 2011

This paper reviews the claimed pivotal role of emotional intelligence (EI) in well‐being and health. Specifically, we examine the utility of EI in predicting health and well‐being and point to future research issues that the field might profitably explore. EI is predictive of various indicators of well‐being, as well as both physical and psychological health, but existing research has methodological limitations including over‐reliance on self‐report measures, and neglect of overlap between EI and personality measures. Interventions focusing on emotional perception, understanding and expression, and emotion regulation, seem potentially important for improving health and well‐being, but research on EI has not yet made a major contribution to therapeutic practice. Future research, using a finer‐grained approach to measurement of both predictors and criteria might most usefully focus on intra‐ and inter‐personal processes that may mediate effects of EI on health.

Temporal stability and species specificity in bacteria associated with the bottlenose dolphins respiratory system
Authors: Lima Nicole , Rogers Tracey , Acevedo‐Whitehouse Karina , Brown Mark V.
Published: November 2011

We demonstrate that the exhaled breath condensate, or ‘blow’, from marine mammals can be used to examine respiratory associated microbial communities using non‐invasive sampling methods. Blow samples from two species of bottlenose dolphin, Tursiops truncatus and T. aduncus, along with hybrid offspring, were examined using molecular microbial ecology methods. A temporal analysis revealed that microbial community structure of each individual remained distinct from other individuals over a two‐month period, indicting strong host specificity. The taxonomic composition of samples, based on pyrosequencing of the V1–V3 regions of the 16S rRNA gene, from 24 healthy individuals was dominated by the Cardiobacteraceae lineage of Gammaproteobacteria, comprising on average 52% of sequences in all samples. Sequences in this taxa were associated with novel clades that contain only sequences from dolphin respiratory tracts. Other genera that likely form part of the core biota include the Saccharospirillaceae (Gammaproteobacteria), Arcobacter (Epsilonproteobacteria), Hydrogenimonaceae (Epsilonproteobacteria), Halotalea (Gammaproteobacteria), Aquimarina (Flavobacteria) and Helococcus (Clostridia). Significant differences between samples from different species were observed only at the species/ strain level, driven by the relative contributions of strains from the most common phylogenetic lineages. Analysis of communities associated with hybrid animals provides tentative evidence for a paternal role in community assembly. Clear overlap was observed with data collected by capture and swabbing of bottlenose dolphins blowholes, indicating this method provides a novel non‐invasive alternative to monitoring marine mammal population health.
A Moving Base Simulator Investigation of Effects of a Yaw Stability System Caused by a Side Impact
Authors: Andersson Anders , Jansson Jonas
Published: November 2011

The main objective of this study was to investigate how an electronic stability control (ESC) system may aid the driver in a critical sideswipe accident. Another objective was to investigate the possibility of having a realistic simulation of a sideswipe accident in a large moving base simulator. The experiment can be divided into two parts. In part one, the driver is unaware of the sudden side impact and in part two, the side impact was repeated six times. The experiment was driven by 18 persons. With the ESC system active no driver lost control, while with the system inactive there were five drivers that lost control in part one. In part two, the ESC system showed to stabilize the vehicle faster, and the improvement in stabilization time was between 40% and 62%. It was also seen that 2% loss of control occurred with an ESC system active and 45% without.
Some Common Fixed Point Theorems in Partial Metric Spaces
Authors: Karapınar Erdal , Yüksel Uğur
Published: November 2011

Many problems in pure and applied mathematics reduce to a problem
of common fixed point of some self‐mapping operators which are defined
on metric spaces. One of the generalizations of metric spaces is the partial
metric space in which self‐distance of points need not to be zero but the
property of symmetric and modified version of triangle inequality is satisfied. In this paper, some well‐known results on common fixed point are
investigated and generalized to the class of partial metric spaces.
Homicide and Associated Steroid Acute Psychosis: A Case Report
Authors: Airagnes G. , Rouge-Maillart C. , Garre J.-B. , Gohier B.
Published: November 2011

We report the case of an old man treated with methylprednisolone for chronic lymphoid leukemia. After two months of treatment, he declared an acute steroid psychosis and beat his wife to death. Steroids were stopped and the psychotic symptoms subsided, but his condition declined very quickly. The clinical course was complicated by a major depressive disorder with suicidal ideas, due to the steroid stoppage, the leukemia progressed, and by a sudden onset of a fatal pulmonary embolism. This clinical case highlights the importance of early detection of steroid psychosis and proposes, should treatment not be stopped, a strategy of dose reduction combined with a mood stabilizer or antipsychotic treatment. In addition have been revised the risks of the adverse psychiatric effects of steroids.
Expanding Interaction Potentials within Virtual Environments: Investigating the Usability of Speech and Manual Input Modes for Decoupled Interaction
Authors: Stedmon Alex , Bayon Victor , Griffiths Gareth
Published: November 2011

Distributed technologies and ubiquitous computing now support users who may be detached or decoupled from traditional interactions. In order to investigate the potential usability of speech and manual input devices, an evaluation of speech input across different user groups and a usability assessment of independent-user and collaborative-user interactions was conducted. Whilst the primary focus was on a formative usability evaluation, the user group evaluation provided a formal basis to underpin the academic rigor of the exercise. The results illustrate that using a speech interface is important in understanding user acceptance of such technologies. From the usability assessment it was possible to translate interactions and make them compatible with innovative input devices. This approach to interaction is still at an early stage of development, and the potential or validity of this interfacing concept is still under evaluation; however, as a concept demonstrator, the results of these initial evaluations demonstrate the potential usability issues of both input devices as well as highlighting their suitability for advanced virtual applications.

Published: November 2011

The development of a novel label-free graphene sensor array is presented. Detection is based on modification of graphene FET devices and specifically monitoring the change in composition of the nutritive components in culturing medium. Micro-dispensing ofEscherichia coliin medium shows feasibility of accurate positioning over each sensor while still allowing cell proliferation. Graphene FET device fabrication, sample dosing, and initial electrical characterisation have been completed and show a promising approach to reducing the sample size and lead time for diagnostic and drug development protocols through a label-free and reusable sensor array fabricated with standard and scalable microfabrication technologies.
A Critical Appraisal on the Role of Varicocele in Male Infertility
Authors: Miyaoka Ricardo , Esteves Sandro C.
Published: November 2011

Varicocele is a major cause of male infertility, as it may impair spermatogenesis through several distinct physiopathological mechanisms. With the recent advances in biomolecular techniques and the development of novel sperm functional tests, it has been possible to better understand the mechanisms involved in testicular damage provoked by varicocele and, therefore, propose optimized ways to prevent and/or reverse them. Up to now, there is still controversy involving the true benefit of varicocele repair in subfertile men as well as in certain specific situations such as concomitant contralateral subclinical varicocele or associated nonobstructive azoospermia. Also, with the continued development of assisted reproductive technology new issues and questions are emerging regarding the role of varicocelectomy in this context. This paper reviews the most recent data available on the pathogenesis, diagnosis, and management of varicocele with regard to male infertility.
Suppression of Retinal Neovascularization by Lentivirus-Mediated Netrin-1 Small Hairpin RNA
Authors: Xu Huizhuo , Liu Jiaolian , Xiong Siqi , Le Yun-zheng , Xia Xiaobo
Published: November 2011

Objectives: The function of netrin-1 in pathological angiogenesis and its role in retinal neovascularization were investigated in the retinas of oxygen-induced retinopathy (OIR) mice by inhibition of netrin-1. Methods: Expression of netrin-1 mRNA and protein in the retinas of OIR mice was analyzed by quantitative RT-PCR and immunoblotting. Inhibition of retinal neovascularization was achieved by lentivirus-mediated netrin-1 small hairpin RNA (shRNA) infection. Retinal neovascularization was examined by fluorescein angiography and quantification of preretinal neovascular nuclei in retinal sections. Results: Both mRNA and protein expression of netrin-1 were significantly upregulated in postnatal day 17 OIR mouse retinas. Treatment of OIR mice with specific lentivirus-mediated netrin-1 shRNA dramatically reduced neovascular outgrowth into the inner limiting membrane. Neovascular tufts and nonperfused areas were also reduced. Conclusions: High expression of netrin-1 was detected in the retina under ischemic conditions and played a significant role in pathological retinal angiogenesis. Therefore, netrin-1 represents a potential therapeutic target for diabetic retinopathy, retinopathy of prematurity and other ocular neovascular diseases.
The Choice between Politics-Oriented and Risk-Oriented Management in Korea: Transition to Manage All Kinds of Risks
Authors: Ha Kyoo-Man
Published: November 2011

Abstract

This article aims to facilitate the transition from politics-oriented management to risk-oriented management in the field of Korean emergency management by analyzing the barriers and alternatives around three key players, namely, (1) the National Assembly, (2) the National Emergency Management Agency, and (3) business corporations. These three players have continued to focus on managing both fire and flood due to typhoon by utilizing politics-oriented management. In other words, when the other risks occur, Korea will surely face related catastrophe. Therefore, it is urgent for Korea to manage all kinds of risks equally, including fire and flood due to typhoon, by embarking on risk-oriented management.
De glazeniersfamilie Crabeth en hun werkzaamheden in Saint-Hubert d'Ardenne
Authors: de Groot Wim
Published: November 2011

The intention of my article is to reopen the investigation into the heritage of the Crabeth family and their activities as glaziers of stained-glass windows along with other works of art they produced in the sixteenth century.

For a long time it was believed that Pieter Dircksz Crabeth and his famous sons Dirck and Wouter originated from Gouda, where they achieved their greatest work: eighteen stained-glass windows for Sint Janskerk. In my contribution I give an account of the pre-Gouda period and make clear that their field of activities was wider and more far-reaching than is commonly agreed upon.

Profiles of their patrons provide an insight into the network to which the Crabeths belonged. Their contacts with the land of Cuijk and the prince bishopric of Liège have been investigated and documented.

Count Floris of Egmond-Buren and his commission to Pieter Crabeth to make eight windows for his castle in Grave in 1522 is highlighted. Research shows a patronage relationship between the house of Egmond and the Crabeth family.

In a letter written by Abbott Nicolas de Malaise we find evidence of a stay by Dirck and Wouter Crabeth at Saint Hubert d'Ardenne around 1523 due to the rebuilding of the abbey church in Renaissance style. The impetus for this letter was a fatal accident caused by Wouter Crabeth's horse. The article goes into the judicial implications of such an event and the consequences for the person involved at that time. The letter expresses the abbot's concern about Wouter's stay in Saint-Hubert with regard to the continuity of the building project.

Twenty years later Pieter and Dirck Crabeth are again invited by Abbott Remacle de Marche to produce stained-glass windows for the abbey church in Saint Hubert, which had been destroyed by fire in the intervening years. The window of Adolf von Schauenburg, who later became archbishop of Cologne, is a wonderful example from this period and it is the only known glass by Pieter Crabeth still in situ. Research into stylistic elements of the rendering of the suffragan bishop in the Gouda cartoon Confirmatio and the patron saint Lambert in the Schauenburg window show a remarkable resemblance between the two figures.

In view of the activities of the Crabeths in Saint Hubert d'Ardenne, critical research is called for into the authorship of the windows in the bishopric of Liège and the probability of the glaziers being involved in glass production studios in its capital.

New insights based upon thorough studies of material and written sources with detailed notes and glosses, along with recent archival investigations, are presented here in the hope that discussion about Pieter Crabeth and his sons Dirck and Wouter will be given new life and put into a wider perspective.
An Extension of Power: Criminal Justice, Law Enforcement, and Elite Rule in the South Carolina Lowcountry on the Eve of the American Revolution
Authors: Palmer Aaron J.
Published: November 2011

South Carolina's highly centralized and effective criminal justice system was an important extension of elite political power throughout the colony. It served two major functions: first, it served to protect property, the ultimate source of political power for the planter and merchant classes who ruled South Carolina as it supplied wealth, social status and the opportunity to hold high office. Second, by protecting property (even though the system often focused on elite property) and upholding order, the lowcountry elite united their interests with the interests of the general population who would also benefit from protection against property crime and disorder. Since the lowcountry elite also had to control a vast number of slaves and had to rely on all of the colony's white population to do so, providing effective government could serve as an important way to cultivate popular support. This paper examines the workings of South Carolina's criminal justice system and that system's priorities. By studying patterns in prosecution and punishment, one can see that the courts successfully attended to elite priorities.
Disambiguating the Term “Chinese”: An Analysis of Chinese American Surname Naming Practices
Authors: Leung Genevieve Y
Published: November 2011

AbstractThe term “Chinese” can refer to an ethnicity, a group of people, or language(s). This conflation makes disentanglement especially difficult, yet not disambiguating perpetuates an oversimplification of a nation, languages, peoples, and cultures. While this blanket term collapses plurality into a monolithic entity, the converse seems to hold when looking at Romanized naming practices of Chinese Americans. The alphabetic rendition of Chinese American names draws relatively clear boundaries of country of origin and general time of arrival to the United States. This paper problematizes the term “Chinese” and looks at the Chineses like Cantonese and Hoisan-wa, which have long overlooked histories in the United States and hold critical clues to disambiguating the cultural and linguistic pluralities of what many would lump together as an immutable term. These findings have implications for using this naming phenomenon to raise linguistic awareness and for the teaching of Chinese American history.
Myosin-X: a MyTH-FERM myosin at the tips of filopodia
Authors: Kerber Michael L. , Cheney Richard E.
Published: November 2011

Myosin-X (Myo10) is an unconventional myosin with MyTH4-FERM domains that is best known for its striking localization to the tips of filopodia and its ability to induce filopodia. Although the head domain of Myo10 enables it to function as an actin-based motor, its tail contains binding sites for several molecules with central roles in cell biology, including phosphatidylinositol (3,4,5)-trisphosphate, microtubules and integrins. Myo10 also undergoes fascinating long-range movements within filopodia, which appear to represent a newly recognized system of transport. Myo10 is also unusual in that it is a myosin with important roles in the spindle, a microtubule-based structure. Exciting new studies have begun to reveal the structure and single-molecule properties of this intriguing myosin, as well as its mechanisms of regulation and induction of filopodia. At the cellular and organismal level, growing evidence demonstrates that Myo10 has crucial functions in numerous processes ranging from invadopodia formation to cell migration.
Arylethynylanthraquinone and Bis(arylethynyl)anthraquinone: Strong Donor–Acceptor Interaction and Proton-induced Cyclization to Form Pyrylium and Dipyrylium Salts
Authors: Sakamoto Ryota , Rao Koya Prabhakara , Nishihara Hiroshi
Published: November 2011

In this account we describe ethynylene-conjugated arylethynylanthraquinone (ArAq) and bis(arylethynyl)anthraquinone (Ar2Aq) which possess ferrocene, triarylamine, platinadithiolene complex, p-methoxybenzene, p-methylbenzene, m-methylbenzene, and benzene as electron-donating arenes (Ar), and anthraquinone (Aq) as an electron acceptor. This series of compounds features donor–acceptor (D–A) interactions: (1) Expression of intramolecular charge-transfer (ICT) transitions; (2) flexible single crystal networks constructed by intermolecular D–A π–π stacking, which undergo guest-induced reversible crystal-to-crystal transformations. In addition, ArAq and Ar2Aq experience proton-induced cyclization so as to produce pyrylium and dipyrylium salts. These salts feature further expanded π-conjugation and stronger D–A interaction: (1) More red-shifted ICT transitions and narrower HOMO–LUMO gaps; (2) bright fluorescence; (3) valence tautomerism (VT); (4) unique reactivities.

Published: November 2011

The electrocatalytic oxidation of formic acid (FA) at Pt–Au nanoparticle (NP)-modified glassy carbon (GC) electrode has been investigated. The catalytic activity toward the electrooxidation of FA was greatly influenced by the method of the electrode preparation. The highest catalytic activity was obtained on Pt/Au/–NH2/GC electrode in which the GC electrode was chemically modified with gold nanoparticles (AuNPs) and Pt nanoparticles (PtNPs) were next electrochemically deposited on top of AuNPs.
A Technique for Improving the Retention of Dentures Retained by Ramus Frame Implants
Authors: Hsu Yung-tsung , Sigurjonsson Jon Olafur , Montes Carlos A. Polo
Published: November 2011

Retention for a denture on a ramus frame implant is usually less satisfactory. The friction between the frame and denture is not reliable. Locking-type attachments require manual dexterity, which could be a problem for many patients. This article presents a technique of cementing the stud-type attachments to the ramus frame to convert the retention mechanism from one that uses the friction between the acrylic resin and ramus frame to a conventional resilient precision attachment. The retention can also be adjusted by changing the nylon inserts.

Satisfação corporal e características de lipodistrofia em crianças e adolescentes com HIV/AIDS em uso de terapia antirretroviral de alta potência
Authors: Silva Querino Haesbaert da , Pedro Fábio Lopes , Kirsten Vanessa Ramos
Published: November 2011

OBJETIVO: Verificar a presença de alterações metabólicas e corporais e satisfação corporal em crianças e adolescentes em uso de terapia antirretroviral. MÉTODOS: Estudo transversal de 38 jovens entre seis e 18 anos infectados por HIV e atendidos entre dezembro de 2009 e maio de 2010. A satisfação corporal foi avaliada por escala de silhuetas, composta por 11 figuras. O estado nutricional foi avaliado por meio de mensurações de peso, altura, circunferências e pregas cutâneas. A presença de características de lipodistrofia foi avaliada pelo exame físico e o perfil lipídico e glicêmico foi solicitado no dia da consulta. Na análise estatística, aplicou-se o teste t e do qui-quadrado, sendo significante p<0,05. RESULTADOS: A maioria dos 38 jovens era eutrófica, com estatura adequada para idade, e 26% apresentavam sobrepeso/obesidade. O colesterol total esteve adequado em 29% dos pacientes. As mudanças corporais mais expressivas foram a lipo-hipertrofia na face e na região abdominal. A prevalência de insatisfação corporal foi de 84%. Crianças e adolescentes apresentaram níveis de insatisfação semelhantes; no entanto, as insatisfeitas com o excesso de peso mostravam valores médios mais elevados de índice de massa corporal e prega cutânea tricipital do que os satisfeitos, porém sem relação com a presença de lipodistrofia. CONCLUSÕES: A prevalência de insatisfação corporal nesta amostra não se associou com a lipodistrofia e foi semelhante à de indivíduos saudáveis. No entanto, as alterações morfológicas e bioquímicas requerem atenção das equipes multiprofissionais, de modo que se possam diminuir os riscos de novas enfermidades nos pacientes avaliados.

OBJETIVO: Avaliar se a medida da circunferência da cintura e a relação cintura/estatura (RCE) são preditoras de fatores de risco cardiovasculares em adolescentes do sexo feminino. MÉTODOS: Avaliaram-se 113 adolescentes de 14 a 19 anos quanto à antropometria (peso, estatura e circunferência da cintura), parâmetros bioquímicos e clínicos (colesterol total, LDL-C, HDL-C, triglicerídeos, glicemia de jejum, insulina, homeostasis model assessment to assess insulin resistance - HOMA-IR, leptina, homocisteína e pressão arterial). Considerou-se como ponto de corte de obesidade abdominal valores de cintura e RCE>percentil 90. RESULTADOS: As adolescentes com obesidade abdominal apresentaram valores significantemente maiores de triglicerídeos (exceto para a RCE), insulina, HOMA-IR, leptina, pressão arterial sistólica e diastólica; o HDL-C foi mais baixo no grupo com cintura >percentil 90, porém sem significância estatística (p=0,052). CONCLUSÕES: O presente estudo demonstrou que a cintura e a RCE são medidas úteis para identificar adolescentes do sexo feminino com maior risco cardiovascular; contudo, a circunferência da cintura, isoladamente, apresentou melhor desempenho.

Este estudo teve como objetivo apontar como o fisioterapeuta pode atuar no processo de inclusão de alunos com paralisia cerebral (PC) no sistema regular de ensino. A presente pesquisa foi realizada em três escolas públicas municipais de ensino fundamental, pertencentes a uma Regional de Ensino da cidade de Curitiba. Cada escola foi visitada cinco vezes entre março e abril de 2009, para coleta de dados. A amostra foi composta por três alunos com diagnóstico de Paralisia Cerebral, cognitivo preservado, alfabetizados, idades entre nove e 16 anos. Para avaliar os alunos foram utilizados dois instrumentos: o Protocolo de Observação e a Ficha de Avaliação Neurológica Qualitativa e Descritiva, do Instituto Pequeno Cotolengo do Paraná. Mediante os resultados encontrados foram estabelecidos os objetivos da atuação fisioterapêutica e realizadas intervenções específicas de acordo com as necessidades dos alunos participantes, no período de abril á junho de 2009. Após a realização do estudo, foi possível verificar que a atuação da Fisioterapia sobre a adequação de mobiliários e materiais, orientação para eliminação de barreiras arquitetônicas e conscientização dos profissionais envolvidos na educação, contribuiu para o desenvolvimento do aluno com paralisia cerebral no ambiente escolar.
Percepção de alunos com paralisia cerebral sobre o uso de recursos de tecnologia assistiva na escola regular
Authors: Alves Ana Cristina de Jesus , Matsukura Thelma Simões
Published: November 2011

O Censo Escolar realizado no Brasil em 2006 localizou aproximadamente 29.000 alunos deficientes físicos matriculados em classes comuns. A escolarização da criança com comprometimento motor na escola comum tem sido discutida juntamente com as possíveis estratégias que possam colaborar para a participação e aprendizagem desse aluno. Uma das estratégias indicadas tem sido o uso de recursos de tecnologia assistiva para favorecer a execução das tarefas pedagógicas, porém pouco se sabe sobre a implementação, a eficácia ou as contribuições desses recursos no processo de escolarização da criança com deficiência física. O objetivo desta pesquisa foi identificar, a partir do ponto de vista do aluno com paralisia cerebral, as contribuições, dificuldades e o cotidiano implicado no uso de recursos de tecnologia assitiva no contexto da escolarização no ensino regular. Participaram deste estudo cinco alunos com diagnóstico de paralisia cerebral nível motor IV e V segundo o Sistema de Classificação da Função Motora Grossa para paralisia cerebral - GMFCS. Foi utilizado um roteiro de entrevista semiestruturado com as crianças e os dados obtidos foram transcritos e analisados na íntegra, optando-se em realizar uma categorização de acordo com os temas da entrevista. As percepções das crianças foram relevantes e elas mostraram-se capazes de apontar demandas e identificar quando e como os recursos podem ser limitantes dentro do contexto. Assim, considerar as opiniões e a participação da criança na identificação de recursos de tecnologia pode contribuir na compreensão do impacto, das demandas e das possíveis contribuições no processo de implementação e utilização do recurso de tecnologia assistiva.
Strong self‐limitation promotes the persistence of rare species
Authors: Yenni Glenda , Adler Peter B. , Ernest S. K. Morgan
Published: November 2011

Theory has recognized a combination of niche and neutral processes each contributing, with varying importance, to species coexistence. However, long‐term persistence of rare species has been difficult to produce in trait‐based models of coexistence that incorporate stochastic dynamics, raising questions about how rare species persist despite such variability. Following recent evidence that rare species may experience significantly different population dynamics than dominant species, we use a plant community model to simulate the effect of disproportionately strong negative frequency dependence on the long‐term persistence of the rare species in a simulated community. This strong self‐limitation produces long persistence times for the rare competitors, which otherwise succumb quickly to stochastic extinction. The results suggest that the mechanism causing species to be rare in this case is the same mechanism allowing those species to persist.
Double Whammy for a New Breed of Foreign-Educated Nurses: Lived Experiences of Filipino Physician-Turned Nurses in the United States
Authors: Vapor Victor R. , Xu Yu
Published: November 2011

This phenomenological study examined the lived experiences of eight self-identified Filipino physician-turned nurses working in Las Vegas in the United States. Participants were interviewed, and audiotaped interviews were transcribed verbatim. Meanings of significant statements and clusters of themes and subthemes were then generated using the Colaizzi’s (1978) method. In addition, van Manen’s (1990) existentials of lived world was adopted to interpret the collected data. The results of the study revealed that the experiences of these Filipino physician-turned nurses involved multidimensional challenges captured in three themes in context of cross-national and transprofessional migration. As a result, they faced a “double whammy” adjustment to a new cultural and work environment common to all foreign nurses (cultural adaptation) and unique identity/role change from physician to nurse (transprofessional adaptation)—that made their transition especially challenging, resulting in short-lived nursing careers at the bedside. Tailored transition programs for physician-turned foreign nurses are needed to address their transprofessional adaptation. In addition, costs and benefits of recruiting and employing physician-turned foreign nurses as direct caregivers need to be reconsidered in light of this study’s findings.

review provides an overview from selected examples of the on-going research within my laboratory that uses metal compounds to either understand biological processes or that exhibit therapeutic properties overcoming the limitations of existing chemotherapies.
A Streamlined Synthesis of Androstadiene C-17 Ester Derivatives
Authors: Gallou Fabrice , Seeger-Weibel Manuela , Lupp Daniel
Published: November 2011

The development of a fully telescoped synthesis of a derivative of androstadiene C-17 esters made from epoxyparamethasone was demonstrated. This streamlining allowed for the elimination of isolation and solvent change after each synthetic step. Thus it not only drastically reduced the
solvent waste, but also minimized the potential exposure to highly active intermediates thereby increasing the overall yield. The intuitively obvious advantage inherent to lowering the number of solvents was illustrated by applying standard green metrics.

Authors: Rana AA , Kamruzzaman M , Takafuji M
Published: November 2011

A new L-glutamide derived internal C=O group containing HPLC stationary phase was synthesized. The L-glutamide lipid was immobilized on to silica surface through aminopropyltrimethoxysilane (APS) linker. The detailed chemical structure of the compounds leading to the final lipid was characterized by melting point measurement, FTIR, 1H NMR and elemental analysis in each step. Chromatographic properties of silica immobilized N-(pyrinylbutyric) L-glutamic acid, Sil-PBG, were evaluated under reversed phase conditions by separation of different polycyclic aromatic hydrocarbons (PAHs) and the results were then compared with monomeric octadecylated silica stationary phase (ODS). Chromatographic evaluation of the new phase showed promising results for the separation of PAHs.

Published: November 2011

Characteristics of airborne particulate matter (PM2.5 and PM10) and black carbon (BC) concentrations have been studied at Kalabagan and Shishumela sites along Mirpur corridor in Dhaka city. These sites are the major road junction of Mirpur corridor and can represent urban background. Both PM2.5 and PM10 fractions were collected simultaneously from both sites by using Air Metrics samplers. The samplings were done for 7 days from the 19-25 January and 5 days from 27- 31 January 2009 at Kalabagan and Shisumela sites respectively. It was found that the ambient PM2.5 and PM10 concentrations were much higher than the daily Bangladesh National Ambient Air Quality Standard. From reconstructed mass (RCM) method, it was found that about 90% of PM2.5 mass comes from anthropogenic sources like motor vehicles, diesel powered generator and biomass burning sources. Since the samplings were carried out during the wintertime, the long-range transport is also expected to contribute to increase the fine PM mass.

Published: November 2011

The effect of cytokinins on callus proliferation from cotyledons and plantlet development was studied in cotton. The frequency of callus induction was observed on MS medium enriched with a variety of cytokinins in different concentrations. With the increase of cytokinin concentration, the percentage of callus formation, percentage of shoot developing calli and number of shoots/calli were increased. Among the three different cytokinins studied, BA showed the highest performance. The highest percentage of callus (6.55%) and shoot developing calli (5.87%) was obtained on MS with 1.0 mg/l BA. Highest number of shoots (3.02) per calli was observed on MS media supplemented with 1.0 mg/l Kn. The rooting media composed of MS medium, 0.6% agar, sucrose and fortified with 2.0 mg/l NAA induced root development at the highest percentage (41.23%) with maximum number of roots (3.61) per cutting and length of root (3.62 cm) per culture. The plantlets were acclimatized in natural conditions.

Authors: Mollah MSI , Paul NK
Published: November 2011

An experiment was conducted to study the influence of soil moisture, NPK fertilizers and variety on yield and yield components of barley (Hordeum vulgare L.). Plant height, tiller number, extrusion length, spikelet number, plant weight, grain number, 100-grain weight and grain yield were observed highest in the I2 (40 mm irrigation water) and F3 (120N 75P 45K) treatments. I2 (40 mm irrigation water ) and F3 (120N 75P 45K) treatments had the highest consumptive water use (CWU). But the highest water use efficiency (WUE) was observed in the I0 (no irrigation) and F3 treatments. Cultivar BARI-Barley-2 had the highest CWU, while cultivar BL-1 had the highest WUE. Key words: Barley; Irrigation; Fertilizer; Grain yield; Consumptive water use; Water use efficiency. DOI: http://dx.doi.org/10.3329/bjsir.v46i3.9045 BJSIR 2011; 46(3): 369-374

Published: November 2011

This paper presents the design and implementation of a turtle hydrofoil for an Autonomous Underwater Vehicle (AUV). The final design of the AUV must have navigation performance like a turtle, which has also been the biomimetic inspiration for the design of the hydrofoil and propulsion system. The hydrofoil design is based on a National Advisory Committee for Aeronautics (NACA) 0014 hydrodynamic profile. During the design stage, four different propulsion systems were compared in terms of propulsion path, compactness, sealing and required power. The final implementation is based on a ball-and-socket mechanism because it is very compact and provides three degrees of freedom (DoF) to the hydrofoil with very few restrictions on the propulsion path. The propulsion obtained with the final implementation of the hydrofoil has been empirically evaluated in a water channel comparing different motion strategies. The results obtained have confirmed that the proposed turtle hydrofoil controlled with a mechanism with three DoF generates can be used in the future implementation of the planned AUV.
On the Biomimetic Design of Agile-Robot Legs

Published: November 2011

The development of functional legged robots has encountered its limits in human-made actuation technology. This paper describes research on the biomimetic design of legs for agile quadrupeds. A biomimetic leg concept that extracts key principles from horse legs which are responsible for the agile and powerful locomotion of these animals is presented. The proposed biomimetic leg model defines the effective leg length, leg kinematics, limb mass distribution, actuator power, and elastic energy recovery as determinants of agile locomotion, and values for these five key elements are given. The transfer of the extracted principles to technological instantiations is analyzed in detail, considering the availability of current materials, structures and actuators. A real leg prototype has been developed following the biomimetic leg concept proposed. The actuation system is based on the hybrid use of series elasticity and magneto-rheological dampers which provides variable compliance for natural motion. From the experimental evaluation of this prototype, conclusions on the current technological barriers to achieve real functional legged robots to walk dynamically in agile locomotion are presented.

Published: November 2011

Besides the typical short-lived fluorescence with decay times in the nanosecond range, colloidal II/VI semiconductor nanoparticles dispersed in buffer also possess a long-lived fluorescence component with decay times in the microsecond range. Here, the signal intensity of the long-lived luminescence at microsecond range is shown to increase 1,000-fold for CdTe nanoparticles in PBS buffer. This long-lived fluorescence can be conveniently employed for time-gated fluorescence detection, which allows for improved signal-to-noise ratio and thus the use of low concentrations of nanoparticles. The detection principle is demonstrated with a time-resolved fluorescence immunoassay for the detection of C-reactive protein (CRP) using CdSe-ZnS nanoparticles and green light excitation.

Published: November 2011

Purpose.

To compare dietary intakes of nonsmoking adults married to smokers or non-smokers.

Design.

Respondents to the U.S. Department of Agriculture's Continuing Survey of Food Intakes by Individuals (CSFII), 1994 to 1996 (response rate = 76.1% for 2 days of dietary intake). Nonsmoking adults aged 18 and older were grouped according to the smoking status of their spouse.

Setting.

In-home interviews in all 50 states and Washington, D.C.

Subjects.

The selected sample included 757 men and 754 women who were married to nonsmokers, and 197 men and 262 women who were married to smokers.

Measures.

Selected demographic variables, food group servings, food energy, and densities of selected nutrients were compared using χ2 and analysis of covariance.

Results.

Men and women married to smokers had greater (p ⩽ .025) energy-adjusted intakes of total and saturated fat but significantly lower (p ⩽ .05) energy-adjusted intakes of fiber and vitamin A. Men married to smokers consumed significantly more (p < .025) energy-adjusted cholesterol and ethanol but significantly less calcium (p = .026); women married to smokers consumed significantly less (p = .014) energy-adjusted folate. Men married to smokers consumed significantly more (p ⩽ .05) alcoholic beverages, coffee, and soft drinks; women married to smokers consumed significantly less water (p = .014) but more cheese and table sweeteners (p ⩽ .05).

Conclusions.

Nonsmoking men and women who were married to smokers had compromised dietary intakes. Nonsmoking men whose wives smoked, in particular, had unhealthy diets due to elevated intakes of fat and cholesterol and low intakes of vitamin A, calcium, and fiber. Health professionals should continue to provide tobacco cessation instruction and dietary guidance, but also be aware of at-risk patients' immediate family members who likely share an increased risk of disease because of poor diet quality and exposure to environmental tobacco smoke.
