Design Reliability Analysis of Cold-Formed Thin-Walled Steel Members with Lipped Channel Sections Considering Distortional Buckling
Authors: Xingyou Yao 
Published: November 2017

Introduction:
Based on the experimental results of cold-formed thin-walled steel lipped channel sections, the uncertainty of calculating mode of load-carrying capacity using effective width method considering distortional buckling for different material types cold-formed steel compressed members was researched, and the uncertainties of material strength and geometric characteristics of the typical sections were statistically analyzed.

Methods:
According to the recommended resistance of partial coefficient in the draft of Technical code of cold-formed steel structures (GB50018-), the reliability indexes of cold-formed thin-walled steel lipped channel sections under compression were investigated using the improved first-order second-moment method considering different possible external loading combinations.

Results:
The analyzed results show that, using the recommended resistance partial coefficient in the code draft, the reliability indexes of the compressed members with width-thickness ratio within the limitation of code draft can well met the target reliability index. The suitability of the corresponding calculating modes of load-carrying capacity considering distortional buckling was established.

Published: November 2017

The study had been conducted to find out the growth of Balinese cows which getting basic ration of spear grass (Heteropogoncontortus) and Angsana leaf that had been supplemented with Silk tree leaf (Paraserianthes falcataria L.). The study was using complete randomized block design with 4 ration treatments and 3 times repetition. Each repetition was using three Balinese cows. The weight of cows being used were in the range of: 83-181 kg. Basic ration being given was arranged based on the percentage of dry ingredients namely: 80% of spear grass + 20% of Angsana leaf (A), 80% of spear grass + 20% of Angsana leaf + 10% of silk tree leaf (B), 80% of spear grass + 20% of Angsana leaf + 15% of silk tree leaf (C), and 80% of spear grass + 20% of Angsana leaf + 20% of silk tree leaf (D), The variables being measured were: dry ingredients consumption, nutrients consumption, body weight gain and Feed Conversion Ratio. The result of study showed that with administration of 20% of silk tree leaf in basic ration was significantly improving (P< 0.05) the consumption of dry ingredients and nutrient, and daily weight gain. The result of study concluded that with administration of silk tree leaf in basic ration of spear grass and Angsana leaf increased the growth of Balinese ox.

Turbine blade tip aero-thermal management: Some recent advances and research outlook
Authors: Zhang Qiang , He Li 
Published: November 2017

AbstractThis article provides an overview of some recent progress in understanding HP turbine blade shroudless tip heat transfer and aerodynamics, especially in a transonic regime. The review is mostly based on the experimental and numerical efforts the authors have been involved in during the past ten years. Some fundamental flow physics especially in high speed Over-Tip-Leakage (OTL) flows are highlighted, including tip choking, shock waves, and the roles played by flow turbulence, etc. These mechanisms bring qualitative differences in tip heat transfer and loss generation, and prospects in tip aerothermal management and control. Of great interest is the strong OTL flow–coolant interaction, which can dramatically affect the tip aerodynamics, and thus would challenge any “optimized” tip geometry based on an uncooled configuration. It is suggested that optimal tip aero-thermal configurations should be an iterative process between blade tip shaping and cooling injection scheme. Combining tip geometry shaping and cooling injection patterns concurrently may provide more extensive exploitation of tip aerothermal design space.

Nitrogen use efficiency (NUE) plays an important role on plant adaptation to the low nutrient conditions. Transformation system from natural forest to oil palm plantation changedthe NUE and soil nutrition in ecosystem. However, how the transformation system affects NUE, N resorption, and soil nutrition in Sarolangun, Jambi province still unknown. The aims of the study were (1) to quantify NUE and Nresorptionand its correlation to N soil content (2)to determine nitrogen loss of litterfall in natural forest (HA) and oil palm plantation (KS) in Sarolangun, Jambi. The result showed that NUE in plant scale (NUE c) influenced by N resorption. NUE c increased with increasing of N resorption. Nitrogen and carbon content of the soil in HA was higher than that of in KS. There was no correlation between N soil content with foliar N content, N resorption, and NUE c. NUE in ecosystem scale (NUEES) was higher in HA than that of in KS. There was 68.3% of total N productionloss or out from the system inKS.

Desde seu surgimento, a Educação Matemática vem se consolidando como uma área de pesquisa. Dada sua natureza multifacetada, estudos Estado da Arte são importantes para apontar tendências e lacunas de suas linhas investigativas. Destarte, esse artigo visa mapear e caracterizar trabalhos sob o aporte da Teoria de Galperin disponíveis em duas bibliotecas digitais. Sendo uma pesquisa Estado da Arte, selecionamos 15 estudos e os categorizamos em função de: curso, instituição, níveis e modalidades de ensino e conteúdos abordados. Verificamos nas investigações: a prevalência em mestrados profissionais, distribuição em todas as regiões brasileiras, do Ensino Fundamental ao Superior e nas modalidades Educação Especial e Educação a Distância, tratando de todas as subáreas da Matemática da Educação Básica. Assim, é fundamental que novas investigações sobre a Teoria de Galperin sejam empreendidas, visando contribuir para difusão de uma perspectiva de educação escolar voltada para o desenvolvimento integral dos estudantes

Authors: Cardoso Gracimar , Madruga Zulma 
Published: November 2017

Este artigo objetiva apresentar uma proposta de atividades introdutórias ao conceito de função linear para escolas inseridas em regiões extrativistas, na qual se faz relação entre a Etnomatemática e a Modelagem Matemática. Para tanto, foi elaborada uma sequência de ensino para o 9º ano do Ensino Fundamental, a qual visa valorizar os conhecimentos dos trabalhadores em suas rotinas diárias – caça e venda de caranguejo em manguezais de cidades localizadas no sul da Bahia – e relacioná-los com o estudo de conteúdos de Matemática. O trabalho defende a ideia de que é possível construir atividades de modelagem para a introdução do conceito de função linear, utilizando-se do enfoque da Etnomodelagem. Acredita-se que a aplicação da sequência poderá tornar a aprendizagem mais significativa, no qual estudantes desse contexto cultural poderão ver sentido para a aprendizagem da Matemática.
