The Use of a Wiki to Facilitate Collaborative Learning in a South African Physiotherapy Department
Authors: Rowe M.
Published: June 2017

The dominant form of teaching in higher education remains the lecture,even though evidence suggests that it alone is inadequate to facilitate the development ofthe higher order thinking skills required in clinical practice. The use of wikis may have a roleto play in facilitating collaborative learning practices that are important for professionaldevelopment. This descriptive survey evaluated the use of a wiki for a collaborative learningactivity within small groups of undergraduate physiotherapy students in a South Africanuniversity. Students participated in a wiki-based assignment and were then surveyedusing open- and closed-ended questions to determine their perceptions and experiences of the process. The results indicate thatalthough a wiki can be used to develop relevant content, there were significant challenges in its implementation. These included apoor understanding by students of how to work effectively in groups, a lack of physical and epistemological access to the internet,and the need for adequate preparation and support. Some features of the wiki were found to have an impact on the quality ofthe work produced, including the use of Discussion pages, peer review, and the public nature of the wiki. The conclusion is thatwikis may have a role to play in collaborative groupwork, but that that students need to be adequately prepared and supportedthroughout the process.
Physiotherapy management strategies for woman post-ceasarean section delivery in public hospitals in KwaZulu-Natal, South Africa
Authors: Reddy P. , Frantz J.
Published: June 2017

South Africa has seen a steady increase in the rate of caesarean section deliveries, and while physiotherapists are often requested to treat these patients, there are no guidelines on their physiotherapeutic management. Current treatment is therefore based on clinical presentations of the patient. This paper reports on the physiotherapy management strategies for women post-caesarean section delivery used at four public hospitals in KwaZulu-Natal during 2011-2012. The study used a quantitative, cross-sectional, descriptive design. The sample consisted of 31 physiotherapists who completed an anonymous self-administered questionnaire, of whom eight had not treated post-caesarean section delivery women at all in the one year period. The results showed mobilization (100%), breathing exercises (94%) and education (94%) were common choices, with 68% selecting pelvic floor exercises as part of their management strategy. The study concluded that the current physiotherapy management strategy for women post-caesarean section delivery is based mainly on the doctors’ referral. Due to their limited knowledge about physiotherapy treatment, doctors overlook other complication(s) and potential complication(s) that could benefit from treatment post-delivery. The study showed that there is a need to improve the role and influence of physiotherapists in the multidisciplinary team.

Voeding en fisieke welstand as deel van die skoolkurrikulum: ’n Intervensie in ’n onderwysopleidingprogram
Authors: De Beer Josef J. , Van Wyk Ben-Erik
Published: June 2017

This article describes education students’ engagement in simulation games during an excursion. The focus is on how the United Nations’ eight millennium development goals could be addressed in teacher education programmes. The authors specifically look at activities that aim to sensitize teachers about HIV and AIDS and food security. They view learning from a neo-Vygotskian perspective known as activity theory, which rates simulation games as the primary strategy for learner involvement. The students become homo ludens(playing human, Huizinga1955), and this facilitates embodied meaningmaking. From this position it is suggested that the particular curriculum holds some promise for exploring HIV and AIDS education, poverty and food security.
Multi-decadal Records of Stratospheric Composition and their Relationship to Stratospheric Circulation Change

Published: June 2017

Abstract. Constituent evolution for 1990–2015 simulated using the Global Modeling Initiative Chemistry and Transport Model driven by meteorological fields from the Modern Era Retrospective analysis for Research and Applications Version 2 (MERRA-2) is compared with three sources of observations: ground based column measurements of HNO3 and HCl from two stations in the Network for Detection of Atmospheric Composition Change (NDACCC, ~ 1990–ongoing); profiles of CH4 from the HALogen Occultation Experiment (HALOE) on the Upper Atmosphere Research Satellite (UARS, 1992–2005); profiles of N2O from the Microwave Limb Sounder on the Earth Observing System satellite Aura (2015–ongoing). The differences between observed and simulated values are shown to be time dependent, with better agreement after ~2000 compared with the prior decade. Furthermore, the differences between observed and simulated HNO3 and HCl columns are shown to be correlated with each other, suggesting that issues with the simulated transport and mixing cause the differences during the 1990s and these issues are less important during the later years. Because the simulated fields are related to mean age in the lower stratosphere, we use these comparisons to evaluate the time dependence of mean age. We use these relationships to account for dynamical variability when determining decadal scale trends in constituents and mean age. The ongoing NDACC column observations provide critical information necessary to substantiate trends in mean age obtained using fields from MERRA-2 or any other reanalysis products.
O clima organizacional e a gestão de pessoas
Authors: Bezerra Ana Lúcia Queiroz
Published: June 2017

Um dos desafios na gestão de pessoas é manter um ambiente de trabalho prazeroso, que permita o crescimento organizacional e o desenvolvimento do potencial intelectual das pessoas.Entre os fatores que permeiam as relações de trabalho e influenciam na satisfação das pessoas temos a motivação do próprio ser humano e o clima organizacional. O indivíduo ao ingressar no mundo do trabalho, de modo geral, é revestido de expectativas, de busca de satisfação tanto das necessidades de pertencer a um grupo social quanto de se auto-realizar. Quando há elevada motivação, o clima se torna favorável e como conseqüência, as pessoas estão satisfeitas, interessadas e colaborativas. Se há baixa motivação em decorrência de frustrações ou barreiras à satisfação de necessidades, o clima organizacional tende a ser desfavorável, gerando estados de depressão, desinteresse, apatia e, até de reclamações generalizadas.Alguns instrumentos podem auxiliar na análise do ambiente organizacional, sendo um deles a Pesquisa de Clima Organizacional que consiste em um levantamento de opiniões, resultando em um mapeamento das percepções sobre o ambiente interno da organização. Pode ser um importante ponto de partida para mudanças com adoção de novas práticas de trabalho. O clima organizacional é considerado uma ferramenta administrativa, um indicador do grau de satisfação dos profissionais em relação a diferentes aspectos da cultura ou realidade organizacional como política e modelo de gestão de pessoas, processo de comunicação e valorização profissional.No contexto da prática da enfermagem, caracterizada por atividades que exigem alta interdependência, a motivação surge como aspecto fundamental na busca de maior eficiência e qualidade na assistência de enfermagem prestada, aliada à satisfação dos trabalhadores. Na prática gerencial da enfermagem, torna-se necessário a utilização da pesquisa de clima organizacional, considerada enquanto busca de possibilidades no desenvolvimento de linhas sensíveis e racionais para a política e modelo de gestão de pessoas. Quanto às pessoas promoverá oportunidades para sugerir mudanças e elevar a auto-estima, com conseqüências positivas na produtividade e qualidade do trabalho decorrente da satisfação pessoal e profissional.

Published: June 2017

Estudo documental, realizado em Hospital Público do Estado de Goiás que teve como objetivos identificar o direcionamento e o foco das ações dos gerentes de enfermagem das Unidades de Internação e verificar o percentual de execução das atividades planejadas. Os dados foram coletados em 2004 extraindo-se dos Planejamentos e Relatórios, elaborados pelos gerentes de enfermagem no período de 1999 a 2004 e organizados em um formulário. Para a análise dos dados produzidos, utilizou-se o programa Excel, versão 2000. Embora planejadas, grande parte das atividades não são executadas. Entre as planejadas e executadas, destacou-se o direcionamento dado às administrativas organizacionais. Quanto ao foco, sobressaíram-se as ações de educação continuada quando direcionadas à assistência, e as normativas quando centradas nas administrativas. Concluiu-se que o enfermeiro executa mais do que planeja. Recomenda-se a realização de outros estudos que possam subsidiar discussões quanto a estes resultados em nosso meio.

O tratamento supervisionado (TS) é um dos pilares da Estratégia DOTS (Directly Observed Treatment Short-course) e sua adoção vem sendo recomendada, para o controle da tuberculose (TB). Neste estudo objetivou-se analisar as potencialidades e fragilidades no processo de expansão do Tratamento Supervisionado (TS) nos seis municípios considerados prioritários para o controle da TB na Paraíba-PB/Brasil. Pesquisa de natureza qualitativa, que utilizou a entrevista semi-estruturada com 21 profissionais envolvidos na implantação e expansão do DOTS nos seis municípios. Os dados foram analisados pela técnica de análise de conteúdo, modalidade temática. Como potencialidades foram identificadas: apoio dos gestores no processo de descentralização do TS para as Unidades de Saúde da Família (USF); compromisso dos profissionais e boa comunicação entre USF e referências. Dentre as fragilidades relatadas observa-se a falta de apoio dos gestores para garantir infra-estrutura e estímulo financeiro para o profissional; falta de qualificação profissional; alta rotatividade dos profissionais e centralização da distribuição de medicamento. Apesar dos esforços para implantação do TS, reconhece-se que sua ampliação esta condicionada a capacidade gerencial e ao compromisso político dos gestores.

Published: June 2017

Estudo documental de abordagem histórico social, cujo objeto foi a trajetória de crescimento dos cursos superiores de enfermagem na região Centro-Oeste do Brasil. Os objetivos foram: levantar o número de cursos superiores de enfermagem criados na região Centro-Oeste, na série histórica 1933-2006; comparar o número de cursos vinculados a instituições públicas aos vinculados a instituições privadas na região em estudo; e comentar os nexos entre o contexto histórico e a configuração desses cursos no que se refere à vinculação institucional, ao longo dos anos. Até o final do ano de 1999, haviam sido criados na região Centro-Oeste 14 cursos de enfermagem, dos quais 57% eram privados e 43% públicos. Em decorrência das políticas de educação adotadas no país, principalmente na década de 90, observa-se a criação de mais 30 cursos na região entre os anos 2000 e 2006, perfazendo um total de 44 cursos superiores de enfermagem, dos quais 79,5% são privados e 20,5% públicos, sendo Goiás, o estado com maior concentração destes cursos. A rede privada expandiu-se na região e concentra, atualmente, a grande maioria dos cursos de enfermagem, o que nos faz entender que a mesma determina, quase que por completo, o perfil do futuro profissional de enfermagem.

Published: June 2017

A quimioterapia utiliza compostos químicos com objetivo de erradicar tumores, mas por não possuir especificidade para células tumorais agridem também células normais, trazendo efeitos colaterais, principalmente, ao aparelho gastrintestinal, causando prejuízo das condições nutricionais do cliente, gerando deficiências e sintomas desagradáveis. Estudo descritivo, exploratório, realizado em 2006 num município do interior do Estado de São Paulo-Brasil, objetivou identificar alterações nutricionais apresentadas pela pessoa com câncer em tratamento quimioterápico, utilizando entrevista e questionário semi-estruturado. Foram consultadas 13 pessoas adultas, com idades acima de 50 anos, portadora de variados tipos de cânceres, em tratamento antineoplásico. O uso de antineoplásicos levou a apresentação de náuseas, anorexia, fadiga, disgeusia, incômodo com odor da comida, constipação, rápida sensação de saciedade, xerostomia e mucosite. A avaliação física revelou alopecia, esclerótica ictérica, unhas manchadas, pele descorada, mucosa oral desidratada, língua saburrosa, alteração nas capacidades físicas para trabalho e perda de peso na maioria deles. As pessoas referiram baixa ingesta hídrica, redução na ingesta alimentar, intolerância a carne e feijão, aumento do consumo de frutas, vegetais, legumes e sucos. Esses dados indicam que o tratamento quimioterápico colabora para a alteração nutricional do doente com câncer apontando para a necessidade de intervenção precoce dos desequilíbrios visando ao sucesso terapêutico.

A proposta deste estudo é um ensaio sobre o tema, mencionando alguns avanços e perspectivas no que tange à reinserção escolar dessas crianças. É importante que a criança com câncer mantenha sua escolaridade, preservando sua vida normal, seu desenvolvimento integral e tenha esperança de cura para construir seu futuro. Porém, sua reinserção escolar tem sido difícil para professores, familiares e para ela própria. Os professores enfrentam dificuldades em como lidar com esta criança frente aos seus colegas de classe e relacionadas à falta de informação sobre a doença. Os familiares sofrem com a preocupação diante da integridade física e emocional da criança, preferindo, muitas vezes, mantê-las em casa. Já as crianças lidam com a desinformação, curiosidade e zombaria, face às mudanças na sua aparência física (perda de peso, queda de cabelo e uso de máscara).

Sepsis is a well-recognized healthcare issue worldwide, ultimately resulting in significant mortality, morbidity and resource utilization during and after critical illness. In its most severe form, sepsis causes multi-organ dysfunction that produces a state of critical illness characterized by severe immune dysfunction and catabolism. Sepsis induces the activation of complement factor via 3 pathways and the release of inflammatory cytokines such as tumor necrosis factor alpha (TNF-α) and interleukin-1beta (IL-1β), resulting in a systemic inflammatory response. The inflammatory cytokines and nitric oxide release induced by sepsis decrease systemic vascular resistance, resulting in profound hypotension. The combination of hypotension and microvascular occlusion results in tissue ischemia and ultimately leads to multiple organ failure. Several clinical and experimental studies have reported that treatment using adsorption of cytokines is beneficial during endotoxemia and sepsis. This review article analyzes the efficacy of CytoSorb® adsorber in reducing the inflammatory response during sepsis. The CytoSorb® adsorber is known to have excellent adsorption rates for inflammatory cytokines such as IL-1β, IL-6, IL-8, IL-10, and TNF-α. Studies have demonstrated that treatment with cytokine adsorbing columns has beneficial effects on the survival rate and inflammatory responses in animal septic models. Additionally, several cases have been reported in which treatment with cytokine adsorbing columns is very effective in hemodynamic stabilization and in preventing organ failure in critically ill patients. Although further investigations and clinical trials are needed, treatment with cytokine adsorbing columns may play an important role in the treatment of sepsis in the near future.

Authors: Eibeck Craig Ashley
Published: June 2017

My research objective was twofold: to gather valuable information regarding the gaps in disability and carer services provided to Indigenous Australian communities of Central Australia and to evaluate plans for expanding these services to better meet the needs of all disabled persons and their carers in the region before the rollout of the National Disability Insurance Scheme (NDIS) in 2018. A questionnaire was personally administered to each of the ten disability or carer agency managers participating in the study, and the managers' responses analyzed. Gaps were found in the transport of Indigenous Australian people to and from Alice Springs to receive services. Gaps were also found in the provision of services for disability housing, outreach accommodation, residential respite, and carer support, as well as for assessment, treatment, counseling, and case management. These gaps increased for all areas of Central Australia the farther the areas were from Alice Springs.

“I’m a mother, but I’m also a facilitator in her every-day life”: Parents’ voices about barriers and support for internet participation among young people with intellectual disabilities
Authors: Sorbring Emma , Molin Martin , Löfgren-Mårtenson Lotta
Published: June 2017

In general, the Internet is an arena where parents (as well as other adults) have limited insight and possibilities to support the young person. However, several studies indicate that parents are one of the most important facilitators in the every-day life of young persons with intellectual disabilities. Therefore, the aim of the current article is to highlight parents’ perceptions and actions in relation to opportunities and barriers for these young people when using the Internet. The empirical material consists of interviews with 22 parents of intellectually challenged young people in Sweden. The transcribed interviews were analysed using a thematic analysis, which is a method of identifying, analysing and reporting patterns within data sets. The results show that parents’ views are double-edged; on the one hand, they see great possibilities for their children, thanks to the Internet, but on the other hand, they are afraid that due to their disability, their children are more sensitive to different contents and interactions on the Internet. Furthermore, the results indicate that parents believe that the Internet can facilitate participation in social life, but that it precludes young people with intellectual disabilities from being part of society in general when it comes to community functions and services. This article will discuss barriers and support in relation to the individual and her or his support system, which brings into focus the parent’s responsibility and support for young people, helping them to surmount barriers – instead of avoiding or ignoring them – and find ways to take action to do so.

Published: June 2017

Ozone concentrations at the Earth's surface are controlled by meteorological and chemical processes and are a function of advection, entrainment, deposition, and net chemical production/loss. The relative contributions of these processes vary in time and space. Understanding the relative importance of these processes controlling surface ozone concentrations is an essential component for designing effective regulatory strategies. Here we focus on the diurnal cycle of entrainment through atmospheric boundary layer (ABL) growth in the Colorado Front Range. Aircraft soundings and surface observations collected in July/August 2014 during the DISCOVER‐AQ/FRAPPÉ (Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality/Front Range Air Pollution and Photochemistry Éxperiment) campaigns and equivalent data simulated by a regional chemical transport model are analyzed. Entrainment through ABL growth is most important in the early morning, fumigating the surface at a rate of ~5 ppbv/h. The fumigation effect weakens near noon and changes sign to become a small dilution effect in the afternoon on the order of −1 ppbv/h. The chemical transport model WRF‐Chem (Weather Research and Forecasting Model with chemistry) underestimates ozone at all altitudes during this study on the order of 10–15 ppbv. The entrainment through ABL growth is overestimated by the model in the order of 0.6–0.8 ppbv/h. This results from differences in boundary layer growth in the morning and ozone concentration jump across the ABL top in the afternoon. This implicates stronger modeled fumigation in the morning and weaker modeled dilution after 11:00 LT.
A 1DVAR‐based snowfall rate retrieval algorithm for passive microwave radiometers

Published: June 2017

Snowfall rate retrieval from spaceborne passive microwave (PMW) radiometers has gained momentum in recent years. PMW can be so utilized because of its ability to sense in‐cloud precipitation. A physically based, overland snowfall rate (SFR) algorithm has been developed using measurements from the Advanced Microwave Sounding Unit‐A/Microwave Humidity Sounder sensor pair and the Advanced Technology Microwave Sounder. Currently, these instruments are aboard five polar‐orbiting satellites, namely, NOAA‐18, NOAA‐19, Metop‐A, Metop‐B, and Suomi‐NPP. The SFR algorithm relies on a separate snowfall detection algorithm that is composed of a satellite‐based statistical model and a set of numerical weather prediction model‐based filters. There are four components in the SFR algorithm itself: cloud properties retrieval, computation of ice particle terminal velocity, ice water content adjustment, and the determination of snowfall rate. The retrieval of cloud properties is the foundation of the algorithm and is accomplished using a one‐dimensional variational (1DVAR) model. An existing model is adopted to derive ice particle terminal velocity. Since no measurement of cloud ice distribution is available when SFR is retrieved in near real time, such distribution is implicitly assumed by deriving an empirical function that adjusts retrieved SFR toward radar snowfall estimates. Finally, SFR is determined numerically from a complex integral. The algorithm has been validated against both radar and ground observations of snowfall events from the contiguous United States with satisfactory results. Currently, the SFR product is operationally generated at the National Oceanic and Atmospheric Administration and can be obtained from that organization.
Geospace system responses to the St. Patrick's Day storms in 2013 and 2015

Published: June 2017

This special collection includes 31 research papers investigating geospace system responses to the geomagnetic storms during the St. Patrick's Days of 17 March 2013 and 2015. It covers observation, data assimilation, and modeling aspects of the storm time phenomena and their associated physical processes. The ionosphere and thermosphere as well as their coupling to the magnetosphere are clearly the main subject areas addressed. This collection provides a comprehensive picture of the geospace response to these two major storms. We provide some highlights of these studies in six specific areas: (1) global and magnetosphere/plasmasphere perspectives, (2) high‐latitude responses, (3) subauroral and midlatitude processes, (4) effects of prompt penetration electric fields and disturbance dynamo electric fields, (5) effects of neutral dynamics and perturbation, and (6) storm effects on plasma bubbles and irregularities. We also discuss areas of future challenges and the ways to move forward in advancing our understanding of the geospace storm time behavior and space weather effects.
Electrostatic Mechanophores in Tuneable Light‐Emitting Piezopolymer Nanowires

Published: June 2017

Electromechanical coupling through piezoelectric polymer chains allows the emission of organic molecules in active nanowires to be tuned. This effect is evidenced by highly bendable arrays of counter‐ion dye‐doped nanowires made of a poly(vinylidenefluoride) copolymer. A reversible redshift of the dye emission is found upon the application of dynamic stress during highly accurate bending experiments. By density functional theory calculations it is found that these photophysical properties are associated with mechanical stresses applied to electrostatically interacting molecular systems, namely to counterion‐mediated states that involve light‐emitting molecules as well as charged regions of piezoelectric polymer chains. These systems are an electrostatic class of supramolecular functional stress‐sensitive units, which might impart new functionalities in hybrid molecular nanosystems and anisotropic nanostructures for sensing devices and soft robotics.
Diketopyrrolopyrrole‐Based Semiconducting Polymer with Both Hydrophobic Alkyl and Hydrophilic Tetraethylene Glycol Chains for Monolayer Transistor and Sensing Application

Published: June 2017

Functional field‐effect transistors (FETs) have received increasing attention in recent years. Herein, it is demonstrated that the incorporation of hydrophilic tetraethylene glycol (TEEG) chains into the diketopyrrolopyrrole (DPP)‐based semiconducting polymer (PDPP3T1) can facilitate the formation of polymeric monolayer at the air–water interface, and the resulting field‐effect transistors (FETs) show sensitive and selective response toward alcohol vapor. By using the Langmuir–Schaefer method, monolayer and ultrathin films from bilayer to five‐layer can be successfully prepared. Interestingly, nanopores with sizes of 50–100 nm are formed within the monolayer film, as observed by using atomic force microscopy. The monolayer FET exhibits relatively high hole mobilities up to 0.014 cm2 V−1 s−1, which is among the highest charge mobilities reported for ultrathin film FETs prepared with the Langmuir technique. Moreover, hole mobility increases with an increase in the thickness of the ultrathin film from monolayer to three‐layer, and it reaches 0.04 cm2 V−1 s−1 for three‐layer FETs. A variation of both on‐current and off‐current is detected for monolayer FET upon exposure to alcohol vapor. The monolayer FET displays ultrahigh sensitivity (down to 1 ppb) and good selectivity toward alcohol vapors, in particular ethanol vapor. This can be attributed to the synergetic effects of the hydrophilic TEEG chains in PDPP3T1 and the nanopores within the monolayers.
Matrix form of Biconjugate Residual Algorithm to Solve the Discrete‐Time Periodic Sylvester Matrix Equations
Authors: Hajarian Masoud
Published: June 2017

There are important relationships between the discrete‐time linear periodic descriptor systems and the discrete‐time periodic matrix equations. In the present paper, we introduce the matrix form of the biconjugate residual (BCR) algorithm for solving the discrete‐time periodic Sylvester matrix equations AiXiBi+CiXi+1Di=Ei,i=1,2,.... It is shown that the introduced algorithm converges to the solutions within a finite number of iterations in the absence of round‐off errors. Finally, three numerical examples are given to demonstrate the efficiency and the performance of the algorithm.
Experimentelle Ermittlung der Desorptionsisothermen von Porenbeton unterschiedlicher Dichte mit der Standardmethode SSS und mit der DVS‐Technik
Authors: Garbalińska Halina , Bochenek Magdalena
Published: June 2017

In dem Artikel wird die Bewertung von zwei Untersuchungsmethoden zur Ermittlung der Desorptionsisothermen – der Standardmethode SSS (Saturated Salt Solution) sowie der DVS‐Technik (Dynamic Vapor Sorption) – vorgestellt. Das Problem der Kompatibilität beider Methoden wird am Beispiel von Porenbeton der folgenden vier Rohdichteklassen getestet: 400, 500, 600, 700 kg/m3. Die erzielten Ergebnisse aus beiden Methoden zeichnen sich durch hohe Konformität bei allen getesteten Porenbetonsorten bei relativen Luftfeuchtigkeiten von 0 bis 75 % aus. Bei hohen Feuchtigkeitswerten zwischen 75–85 % und 98 % wurde ein deutlicher Unterschied im Verlauf der Desorptionsisothermen festgestellt, die mit den beiden Methoden ermittelt wurden, insbesondere bei den höheren Dichteklassen.
Auswertung von Raumklimamessungen und Bestimmung typischer Taupunkttemperaturen in natürlich belüfteten Wohnzimmern
Authors: Hofmann Markus , Geyer Christoph , Kornadt Oliver
Published: June 2017

Für viele bauhysikalische Simulationen und Nachweise wird als wesentliche Eingangsgröße das Raumklima benötigt. Besonders detaillierte Angaben sind für instationäre Berechnungen erforderlich. Literaturangaben über die jahreszeitliche Entwicklung des Raumklimas sind meist recht allgemein gehalten und unterscheiden nicht nach Klimaregion, Belegungsprofil oder Raumnutzung. Ausgewertet wurden Raumklimamessungen aus zwölf Wohnzimmern eines Jahres. Aus den Messwerten werden außentemperatur‐ und zeitabhängige Ausgleichsfunktionen für die Raumlufttemperatur, die Raumluftfeuchte und die Taupunkttemperatur abgeleitet. Während des Messzeitraumes waren die Wohnzimmer schadensfrei und wiesen unterschiedliche Belegungsprofile auf. Aus den Messergebnissen wird ein Raumklimamodell für Wohnzimmer abgeleitet, womit auch eine Überprüfung und Bewertung von Simulationsergebnissen hinsichtlich des Tauwasserrisikos an der Wandoberfläche fensterbelüfteter Wohnzimmer möglich wird.
Integrative Verhandlungen fördern – ein experimenteller Ansatz zur Nutzung farbiger Beleuchtung in Verhandlungssituationen
Authors: Kombeiz Olga , Steidle Anna
Published: June 2017

Das Verhandlungsgeschick der Mitarbeiter trägt in vielen Organisationen wesentlich zum Unternehmenserfolg bei. Gleichzeit weist aktuelle Forschung daraufhin, dass zwischenmenschliches Verhalten zum Beispiel in Verhandlungen durch die physikalische Umgebung beeinflusst werden kann. Die vorliegende Studie untersuchte die Bedeutung des farbigen Lichts für kooperatives Verhalten in integrativen Verhandlungen. Die Autoren nahmen an, dass rotes Licht eine angenehme, sozialfreundliche Raumatmosphäre schafft und somit den Verhandlungserfolg fördert. In einer experimentellen Studie wurde die Lichtfarbe (rot vs. blau und weiß) variiert. Die Ergebnisse bestätigten die Annahme. Der theoretische Wert, Limitationen sowie praktische Implikationen der Befunde werden diskutiert.

Key Clinical Message

Acquired hemophilia is a rare but potentially fatal clinical condition requiring clinical suspicion to reach to a diagnosis, especially in elder patients. This diagnosis should be suspected in patients that present with unexplained persistent bleeding from skin, soft tissues, and mucosa and have a prolonged aPTT.

The aim of this contribution is to provide a comprehensive comparison between chitosan and Moringa oleifera seed flour (MOSF) as coagulant‐flocculants. MOSF was obtained as a byproduct in a biodiesel process. Turbidity and heavy metal ion removal, using both eco‐friendly materials, was assessed. Jar tests were performed on samples taken from river water, agricultural wastewater, and mixed wastewater (contaminated with agricultural and urban residues). Bioflocculant dosages within the range of 0.005–20 mg L−1 were tested. Irrespective of the initial turbidity, the optimal dosage of chitosan and MOSF for decreasing turbidity in river water was 1 and 5 mg L−1, respectively. Furthermore, from river water, Pb removal up to 95% was achieved irrespective of the bioflocculant; for Mn removal, MOSF performed better than chitosan, with the adsorbent trapping close to 90% of this metal. MOSF decreased turbidity levels and heavy metal content (Mn and Pb) to under the permissible limits (Mexican environmental regulation for potable water, NOM‐127‐SSA1‐1994). Additionally, kinetic data were fitted to kinetic models of adsorption for the pollutants. For agricultural wastewater, a chitosan dosage of 10 mg L−1 reduced turbidity to 5–10 nephelometric turbidity units (NTU), and a MOSF dosage of 10 mg L−1 decreased the turbidity to values lower than 5 NTU. For the mixed wastewater, chitosan achieved a high turbidity removal, while MOSF was not suitable.
Gibbs Measures on Mutually Interacting Brownian Paths under Singularities
Authors: Mukherjee Chiranjib
Published: June 2017

We are interested in the analysis of Gibbs measures defined on two independent Brownian paths in ℝd interacting through a mutual self‐attraction. This is expressed by the Hamiltonian with two probability measures μ and ν representing the occupation measures of two independent Brownian motions. We will be interested in a class of potentials V that are singular, e.g., Dirac‐ or Coulomb‐type interactions in ℝ3, or the correlation function of the parabolic Anderson problem with white noise potential.

The mutual interaction of the Brownian paths inspires a compactification of the quotient space of orbits of product measures, which is structurally different from the self‐interacting case introduced in [27], owing to the lack of shift‐invariant structure in the mutual interaction. We prove a strong large‐deviation principle for the product measures of two Brownian occupation measures in such a compactification and derive asymptotic path behavior under Gibbs measures on Wiener paths arising from mutually attracting singular interactions. For the spatially smoothened parabolic Anderson model with white noise potential, our analysis allows a direct computation of the annealed Lyapunov exponents, and a strict ordering of them implies the intermittency effect present in the smoothened model. © 2017 Wiley Periodicals, Inc.

Authors: Kubik Mark , Mandal Rajarsi , Albergotti William , Duvvuri Umamaheswar , Ferris Robert L. , Kim Seungwon
Published: June 2017

Background

The value of transcervical arterial ligation during transoral robotic surgery (TORS) as a measure to decrease postoperative bleeding incidence or severity is unclear.

Methods

A retrospective single institution study was performed to identify risk factors for hemorrhage after TORS for oropharyngeal squamous cell carcinoma (SCC).

Results

Overall, 13.2% of patients (35/265) experience postoperative hemorrhage. T classification, perioperative use of anticoagulants, surgeon experience >50 cases, and tumor subsite were not predictors of postoperative hemorrhage. Of this cohort, 28% underwent prophylactic arterial ligation. The overall incidence of bleeding was not significantly decreased in patients who underwent arterial ligation (12.1% vs 13.6%; p = .84). However, arterial ligation significantly reduced the incidence of major and severe bleeding events (1.3% vs 7.8%; p = .04). Radiation before TORS was a risk factor for major and severe postoperative hemorrhage (p < .02).

Conclusion

Transcervical arterial ligation during TORS may reduce the severity of postoperative hemorrhagic events. © 2017 Wiley Periodicals, Inc. Head Neck 39: 1510–1515, 2017
Strength, toughness, and reliability of a porous glass/biopolymer composite scaffold

Published: June 2017

Development of bioactive glass and ceramic scaffolds intended for the reconstruction of large segmental bone defects remains a challenge for materials science due to the complexities involved in clinical implantation, bone–implant reaction, implant degradation and the multiple loading modes the implants subjected to. A comprehensive evaluation of the mechanical properties of inorganic scaffolds and exploration of new ways to toughen brittle constructs are critical prior to their successful application in loaded sites. A simple and widely adopted approach involves the coating of an inorganic scaffold with a polymeric material. In this work, a systematic evaluation of the influence of a biopolymer, polycaprolactone (PCL), coating on the mechanical performance of bioactive glass scaffolds was carried out. Results from this work indicate that a biopolymer PCL coating was more effective in increasing the compressive strength and reliability of the glass scaffold under compression, but less effective in improving its flexural strength or fracture toughness. This is the first report that reveals the limited successfulness of a polymer coating in improving the toughness of strong scaffolds, suggesting that new and novel ways of toughening inorganic scaffolds should be future research directions for scaffolds applied in loaded sites. © 2017 Wiley Periodicals, Inc.
