Experiment Research on the Inverse Presumption Method to Evaluate Peak Temperature for Post-fire Spatial Structure
Authors: Cui Jing , Yin Lingfeng , Guo Xiaoming , Tang Gan 
Published: November 2017

Introduction:
The peak temperature is one of the most important factors to evaluate the structural damage. Due to the reduction in the tensile strength of the steel, the structural stress is redistributed and the bearing capacity is decreased at the elevated temperature.

Methods:
This paper presents an inverse method to evaluate the peak temperature for the steel structures subjected to fire. An initial temperature field is assumed based on the post-fire structural residual displacement, and a temperature iteration function is developed to approach the peak temperature of the structure in fire by minimizing the difference between the measured and numerical results. An experimental study was conducted to investigate the structural behavior of a spatial structure subjected to fire. The temperature and displacement data were recorded.

Result and Conclusion:
Results show that the measured results have a good agreement with the predicted results, demonstrating that the proposed method in this paper is available for evaluate the peak temperature with a desirable accuracy. The inverse method of the temperature field can provide a theoretical basis for scientifically evaluating the residual displacements of the post-fire structure and formulating reliable repair and reinforcement schemes.

Выполнены исследования спектров магнитопоглощения и спектров межзонной фотопроводимости при различных температурах в квантовых ямах HgTe/CdHgTe с дырочным типом проводимости. Показано, что в образце с нормальной зонной структурой наблюдается сдвиг положения красной границы в сторону больших энергий с ростом температуры, что указывает на увеличение ширины запрещенной зоны в квантовой яме. В образце с инвертированной структурой впервые наблюдалось смещение красной границы в сторону меньших энергий, связанное с топологическим фазовым переходом от инвертированной зонной структуры к прямой с увеличением температуры. Результаты экспериментальных исследований находятся в согласии с теоретическими расчетами зонной структуры, выполненными на основе модели Кейна. DOI: 10.21883/FTP.2017.12.45168.30

Published: November 2017

BackgroundMental health problems are common among youth in high school, and school counselors play a key role in the provision of school-based mental health care. However, school counselors occupy a multispecialist position that makes it difficult for them to provide care to all of those who are in need in a timely manner. A Web-based mental health service that offers screening, psychological therapy, and monitoring may help counselors manage time and provide additional oversight to students. However, for such a model to be implemented successfully, school counselors’ attitudes toward Web-based resources and services need to be measured.ObjectiveThis study aimed to examine the acceptability of a proposed Web-based mental health service, the feasibility of providing this type of service in the school context, and the barriers and facilitators to implementation as perceived by school counselors in New South Wales (NSW), Australia.MethodsThis study utilized an online cross-sectional survey to measure school counselors’ perspectives.ResultsA total of 145 school counselors completed the survey. Overall, 82.1% (119/145) thought that the proposed service would be helpful to students. One-third reported that they would recommend the proposed model, with the remaining reporting potential concerns. Years of experience was the only background factor associated with a higher level of comfort with the proposed service (P=.048). Personal beliefs, knowledge and awareness, Internet accessibility, privacy, and confidentiality were found to influence, both positively and negatively, the likelihood of school counselors implementing a Web-based school mental health service.ConclusionsThe findings of this study confirmed that greater support and resources are needed to facilitate what is already a challenging and emotionally demanding role for school counselors. Although the school counselors in this study were open to the proposed service model, successful implementation will require that the issues outlined are carefully addressed.

Published: November 2017

ABSTRACT

Objectives:
To evaluate the effects of bone regeneration materials and orthodontic tooth movement (OTM) timing on tooth movement through alveolar bone defects treated with guided bone regeneration (GBR) utilizing xenografts (Bio-Oss) and alloplast (β-TCP).

Materials and Methods:
Twenty-four standard alveolar bone defects in six male beagle dogs were treated by GBR using either Bio-Oss or β-TCP (experimental), whereas the control defects were left empty. The defects were further grouped into early or late subgroups, depending on OTM timing after GBR (ie 1 month or 2 months, respectively). Rates of OTM were measured intraorally, while computed tomography scan images were used to assess bone density, alveolar bone height, second premolar displacement, and tipping tendency.

Results:
Generally, the Bio-Oss early and Bio-Oss late subgroups recorded the lowest amount of tooth movement compared with other modes of GBRs assessed. Before OTM, the control group registered significantly lower bone height compared with the Bio-Oss and β-TCP groups (P &lt; .01). The control group was inferior on bone density and bone height compared with Bio-Oss and β-TCP.

Conclusions:
The Bio-Oss group had favorable radiologic features (higher alveolar bone level and bone density with less premolar tipping) but showed slower OTM than the control group. The late OTM subgroup had favorable radiologic features and showed faster tooth movement than the early OTM in the β -TCP group.

Published: November 2017

Abstract
CASE DESCRIPTION Two Pembroke Welsh Corgis with gastrointestinal signs including inappetence, diarrhea, lethargy, and hypersalivation were referred for evaluation.
CLINICAL FINDINGS Diagnostic testing included abdominal ultrasonography and CT angiography. One patient had a cranial mesenteric artery-to-mesenteric vein fistula with multiple acquired extrahepatic portosystemic shunts. The second patient had both cranial and caudal mesenteric artery-to-mesenteric vein fistulas and multiple acquired extrahepatic portosystemic shunts.
TREATMENT AND OUTCOME Both patients underwent minimally invasive coil embolization of the mesenteric arterioportal fistulas, with complete occlusion confirmed by means of angiography at procedure completion. Clinical outcome approximately 1 year after treatment was assessed as fair to good because of recurrence of clinical signs that required medical management in 1 dog and some persistent serum biochemical abnormalities.
CLINICAL RELEVANCE Outcome for the 2 patients described suggested that coil embolization may be a feasible and effective minimally invasive technique for the treatment of mesenteric arterioportal fistulas in dogs. However, further investigation of the potential for chronic hepatic disease in patients with a history of acquired portosystemic shunts is warranted.

Authors: Galvíncio Josiclêda Domiciano 
Published: November 2017

R E S U M OA Caatinga é um biome que sofre com grande variabilidade climática anual e intraanual. Essa variabilidade climática faz com que o bioma em grande parte do ano sofra com grande estresse hídrico. Estudar as relações existentes entre o conteúdo de água na planta e outras variáveis do ecossistemas, tais como: biomassa e evapotranspiração pode auxiliar e prever impactos da escassez hídrica e seca climatológica sobre a produção de biomassa do bioma Caatinga. Assim, este estudo pretende analisar as relações existentes entre o conteúdo de água na folha com a biomassa e evapotranspiração em área do bioma caatinga localizado em São José do Sabugi, Paraiba, Brasil. Foi utilizado o algoritmo SEBAL-Surface Energy Balance para estimar a evapotranspiração e o foram calculados os índices de vegetação NDVI- Normalized Difference Vegetation Index, SAVI- Soil Adjusted Vegetation Index e o índice de conteúdo de água na folha LWCI- Leaf Water Content Index. Os resultados mostraram uma boa relação existente entre os índices de vegetação e o conteúdo de água na folha, sendo r=0.76 para o SAVI e 0.64 para o NDVI. Para a evapotranspiração a correlação foi de r =0.386. Conclui-se que a quantidade de água na folha está altamente correlacionada com a biomassa.Palavra chave: bioma, sazonalidade, seca, semiárido.

Older adults may not consider life expectancy an important factor in cancer screening
Authors: Chung Clement 
Published: November 2017

Key Points

Although many elderly individuals considered their age and health status to be relevant in making decisions regarding cancer screening, they often did not understand the role of life expectancy.
It is important for providers to incorporate patient preference into communication strategies regarding cancer screening.
In the context of good physician‐patient relationships, discussions regarding discontinuing cancer screening generally do not negatively affect older adults' views of their physicians.

Abstract
Reactive oxygen species (ROS) produced by NADPH phagocyte oxidase isoform (NOX2) are critical for the elimination of intracellular pathogens in many infections. Despite their importance, the role of ROS following infection with the eukaryotic pathogen Leishmania has not been fully elucidated. We addressed the role of ROS in C57BL/6 mice following intradermal infection with Leishmania amazonensis. Despite equivalent parasite loads compared with wild-type (WT) mice, mice deficient in ROS production by NOX2 due to the absence of the gp91 subunit (gp91phox−/−) had significantly more severe pathology in the later stages of infection. Pathology in gp91phox−/− mice was not associated with alterations in CD4+ T cell–mediated immunity but was preceded by enhanced neutrophil accumulation at the dermal infection site. Ex vivo analysis of infected versus uninfected neutrophils revealed a deficiency in infection-driven apoptosis in gp91phox−/− mice versus WT mice. gp91phox−/− mice presented with higher percentages of healthy or necrotic neutrophils but lower percentages of apoptotic neutrophils at early and chronic time points. In vitro infection of gp91phox−/− versus WT neutrophils also revealed reduced apoptosis and CD95 expression but increased necrosis in infected cells at 10 h postinfection. Provision of exogenous ROS in the form of H2O2 reversed the necrotic phenotype and restored CD95 expression on infected gp91phox−/− neutrophils. Although ROS production is typically viewed as a proinflammatory event, our observations identify the importance of ROS in mediating appropriate neutrophil apoptosis and the importance of apoptosis in inflammation and pathology during chronic infection.

Abstract
Skin dendritic cells (DCs) are divided into several subsets with distinctive functions. This study shows a previously unappreciated role of dermal CD11b-type Langerin− DCs in maintaining immunological self-tolerance after UVB exposure. After UVB exposure, dermal CD11b-type Langerin− DCs upregulated surface CD86 expression, induced proliferation of Foxp3+ regulatory T (Treg) cells without exogenous Ags, and upregulated a set of genes associated with immunological tolerance. This Treg-expansion activity was significantly hampered by CD80/CD86 blockade in vivo. These results indicate that CD11b-type Langerin− DCs from the UVB-exposed skin are specialized to expand Treg cells in the skin, which suppress autoimmunity.
