A Combined Strain Element in Static, Frequency and Buckling Analyses of Laminated Composite Plates and Shells

This paper deals with numerical analyses of laminated composite plate and shell structures using a new four-node quadrilateral flat shell element, namely SQ4C, based on the first-order shear deformation theory (FSDT) and a combined strain strategy. The main notion of the combined strain strategy is based on the combination of the membrane strain and shear strain related to tying points as well as bending strain with respect to cell-based smoothed finite element method. Many desirable characteristics and the enforcement of the SQ4C element are verified and proved through various numerical examples in static, frequency and buckling analyses of laminated composite plate and shell structures. Numerical results and comparison with other reference solutions suggest that the present element is accuracy, efficiency and removal of shear and membrane locking

Characteristics of shear strength at the interface between two soil layers in ring shear apparatus

The slopes containing discontinuous planes such as bedding planes, rupture, or boundary between two soil layers are often prone to sliding. Thus, the characteristics of shear strength mobilized along the discontinuous planes should be examined. In this study, the shear strength at the interface between two different soil layers will be investigated based on ring shear test. The combined sample comprising of one kaolin layer and one kaolin + bentonite mixture layer was used to simulate the discontinuous planes between two soil layers. A number of ring shear tests were conducted on these samples at a normal stress of 98 kPa and shear rates from 0.02 to 20 mm/min using a multi-stage of shearing rates procedure. The research results indicate that the shear strength at the interface sharply increases to reach the peak value after a small shear displacement, then drops to the residual value. The residual interface strength tends to increase with increasing shear rates above 2 mm/min and the level of increase in residual interface strength depends on the contact surface. Furthermore, the effect of the order sample layer in combined samples can be ignored when determining the peak, the residual interface strengths as well as the rate effect on residual interface strength in the laboratory

A propensity score matching analysis of the relationship between forest resources and household welfare in Vietnam

Using secondary data from a socio-economic quantitative household survey in of the North Central region of Vietnam, the main aim of our study is to analyze the causal effect of forest resources on household income and poverty. Based on the observed characteristics of a forest-based livelihood and forest-related activities, we use a propensity score matching (PSM) method to control for potential bias arising from self-selection. The PSM results indicate that households with a forest livelihood had a higher level of income and lower level of poverty than did those without. Interestingly, our findings confirm that a forest-based livelihood offers much higher income than any other type of livelihood adopted by local households. Also, the poverty rate among households with a forest livelihood is lower than those earning non-labor income or engaged in wage/crop and crop livelihoods. Moreover, households whose livelihoods depend on timber forest products (TFPs) and animals (non-TFPs) also had higher income and lower levels of poverty than did those lacking these resources. Among households and provinces, we find differing opportunities deriving from forest resources, suggesting that there are potential barriers hindering local households from pursuing a forest livelihood or participating in some forest activities. Therefore, government policy and regulations on forest management should focus on improving the access of households to forest resources, at the same time enhancing the sustainability of these resources

MULTI-PIXEL PHOTON COUNTER FOR OPERATING A TABLETOP COSMIC RAY DETECTOR UNDER LOOSELY CONTROLLED CONDITIONS

The multi-pixel photon counter (MPPC) has recently emerged as a great type of silicon photomultiplier to replace or compensate for conventional vacuum-based photomultiplier tubes. An MPPC provides many advantageous features, such as high electrical gain, outstanding photon detection efficiency, fast timing response, immunity to magnetic fields, low-voltage operation, compactness, portability, and cost-effectiveness. This article examines the electrical and optical characteristics of an MPPC under loosely controlled environmental conditions. We also report a measurement of the light yield captured by the MPPC when a cosmic ray passes through the plastic scintillator, demonstrating that such a setup is suitable as a simple, cost-effective tabletop cosmic ray detector for educational and research purposes

Genome Sequence of a Virulent African Swine Fever Virus Isolated in 2020 from a Domestic Pig in Northern Vietnam

This study reports the genome sequence of an isolated African swine fever (ASF) virus (VNUA-ASFV-05L1/HaNam) obtained at the fourth passage on pulmonary alveolar macrophages. The virus was isolated during a typical acute ASF outbreak in pigs in a northern province of Vietnam in 2020

Assessing the price and output effects of monetary policy in Vietnam:evidence from a VAR analysis

Using monthly data, we perform a vector-autoregressive analysis to measure the effects of monetary policy on the Vietnamese economy. We concentrate our attention on the period following the introduction of the Law on Central Bank in January 1998 (which brought the national monetary policy and its objectives in line with international practices). Contrary to previous studies on Vietnam, we find evidence suggesting that monetary policy (through the manipulation of interest rates) is an effective policy tool in stabilizing prices. However, credit growth tends to induce inflationary pressures. In addition, we find that an expansion of broad money supply leads to an increase in industrial production

Ampliación del concepto “Producción más limpia”

“Cleaner production “ (CP) emerged in the aftermath of the 1987 Brundtland Commission (WCED, 1987) call for less and more efficient energy and materials use efficiency and the suggestion to substitute more harmful products (for the environment and health) by less dangerous ones. Cleaner production was the reply of industry to the inter-sectorial and socio-economic call for sustainable development. The technical aims widened. Originally they were targeted to improve en-vironmentally inferior products to less inferior ones. Today the goal is producing is quality products us-ing renewable energy efficiently and producing zero waste, while emitting no pollution.The perspective of the scope also changed from en-vironmental sustainability to the wider “Corporate Social Responsibility” (CSR). This includes that post-modern companies have not only responsibili-ties on their economic performance and the environ-ment, but should also act on issues including human rights and resources, business ethics, and community involvement. This widening of contents necessitates more and better adapted methods. During the past 45 years the number of assessment methods (preventing pollution and its effects) increased significantly from environmental aspects (EIA), over health (HIA) and policy aspects (SEA), to sustainability assessment, addressing not only environmental, but in an inte-grated way also social, economic, and ethical issues of the evaluation.This paper reviews this evolution of ideas. It provides not only the concepts, but is equally based on case studies and examples illustrating different aspects of this evolution. It acts as a guide towards contempo-rary CSR and advocates its support towards educa-tion and research.“Producción más limpia” (CP) surgió a raíz de la Comi-sión Brundtland de 1987 con el objetivo de requerir me-nos energía y de manera más eficiente con respecto a su uso, sugiriendo sustituir los productos más nocivos (por el medio ambiente y la salud) por menos peligroso; la pro-ducción más limpia, fue la respuesta de la industria a la llamada inter-sectorial y socioeconómica para el desarro-llo sostenible. Los objetivos técnicos se abrieron ya que originalmente estaban dirigidos a mejorar los productos de calidad medioambiental inferior a los menos inferio-res. Hoy en día el objetivo es producir productos de calidad utilizando energía renovable eficiente y productoras de re-siduos cero, mientras que emite ninguna contaminación.Desde la perspectiva del ámbito de aplicación se incorpora la sostenibilidad ambiental a la “Responsabilidad Social Empresarial” más ancha (RSE). Esto incluye que las em-presas de post-modernos no sólo tienen responsabilidades sobre su desempeño económico y el medio ambiente, sino que también deben actuar en temas como los derechos hu-manos y los recursos, la ética empresarial, y participación de la comunidad. Esta ampliación de contenidos requie-re más y mejor adaptados métodos. Durante los últimos 45 años el número de métodos de evaluación (prevención de la contaminación y sus efectos) aumentó significativa-mente de los aspectos ambientales (EIA), más de la salud (EIS) y los aspectos de política (SEA), con la evaluación de la sostenibilidad, abordar no sólo el medio ambiente, pero en una también forma integrada social, económica, y las cuestiones éticas de la evaluación.Este documento analiza esta evolución de las ideas. Ofre-ciendo no sólo los conceptos, sino que se basa igualmente en estudios de casos y ejemplos que ilustran diferentes aspectos de esta evolución. Actúa como una guía hacia la RSE contemporánea y aboga por su apoyo hacia la educa-ción y la investigació
