Authors: Wang Min-Wen , Arifin Fatahul , Vu Van-Hanh 
Published: September 2019

Injection molding technology is known as the most widely used method in mass production of plastic products. To meet the quality requirements, a lot of methods were applied in optimization of injection molding process parameter. In this study the optimization based on Taguchi orthogonal array and Grey relational analysis (GRA) is used to optimize the injection molding process parameters on a LED lens. The four process parameters are: packing pressure, injection speed, melt temperature and mold temperature. The multi-response quality characteristics are total displacement, volumetric shrinkage, and thermal residual stress. The optimal molding parameters are packing pressure (90 MPa), injection speed (300 mm/sec), melt temperature (270 °C) and mold temperature (90 °C). The luminous uniformity of the LED is 92.61 % and the viewing angle of the LED is 124.76°. Among the four factors, packing pressure plays the key role in reducing total displacement, volumetric shrinkage, and thermal residual stress.
High Dimensional Parameter Fitting of the Keller–Miksis Equation on an Experimentally Observed Dual-Frequency Driven Acoustic Bubble
Authors: Varga Roxána , Mettin Robert 
Published: September 2019

A parameter identification technique of an underlying bubble model of an experimentally observed single bubble in a cluster under dual-frequency external forcing is presented. The measurements are carried out via high-speed camera recordings at a rate of 162750 frames per second. The used frequencies during the experiment are 25 kHz and 50 kHz. With a digital image processing technique, the measured bubble radius as a function of time is determined. The employed governing equation for the parameter fitting is the Keller–Miksis equation being a second order ordinary differential equation. The unknown four-dimensional parameter space is composed by the two pressure amplitudes, the phase shift of the dual-frequency driving and the equilibrium size of the bubble. In order to obtain an optimal parameter set within reasonable time, an in-house initial value problem solver is used running on a graphics processing unit (GPU). The error function measuring the distance between the numerical simulations and the measurement is based on the identification of the maximum bubble radii during each subsequent period of the external forcing. The results show a consistent estimation of both pressure amplitudes. The optima of phase shift and equilibrium bubble size are less significant due to a valley-like shape of the error function. Nevertheless, reasonable values are found that lead to estimations of pressure and temperature peaks during bubble collapse.
The Bivariate Generalized Rayleigh Distribution
Authors: SARHAN Ammar 
Published: September 2019

This paper introduces a new bivariate distribution named the bivariate generalized Rayleigh distribution (BVGR). The proposed distribution is of type of Marshall-Olkin (MO) distribution. The BVGR distribution has generalized Rayleigh marginal distributions. The joint cumulative distribution function, the joint survival function, the joint probability density function and the joint hazard rate function of the proposed distribution are obtained in closed forms. Statistical properties of the BVGR distribution are investigated. The maximum likelihood and Bayes methods are applied to estimate the unknown parameters. Both maximum likelihood and Bayes estimates are not obtained analytically. Therefore, numerical algorithms are required to report on the model parameters and its reliability characteristics. Markov Chain Monte Carlo (MCMC) algorithm is applied for the Bayesian method. A real data set is analyzed using the proposed distribution and compared it with existing distributions. It is observed that the BVGR model fits this dataset better than the MO and the bivariate generalized exponential (BVGE) distributions.

Introdução: As atividades fí­sicas leves ou moderadas e as vigorosas podem impactar nos distúrbios do assoalho pélvico de maneira bidirecional, uma vez que podem exercer papel protetor para perdas urinárias, bem como constituir-se em fator desencadeador. Estudos voltados í funcionalidade do assoalho pélvico e ao ní­vel de atividade fí­sica de mulheres idosas ainda são escassos. Objetivo: Analisar a funcionalidade dos músculos do assoalho pélvico (MAP) de idosas ativas fisicamente. Métodos: Pesquisa descritiva com 51 idosas (67,8 ± 5,2 anos) praticantes de atividade fí­sica. Inicialmente as idosas responderam a questões de uma ficha diagnóstica. Para avaliação funcional dos MAP foi utilizado o Esquema PERFECT. A avaliação do ní­vel de atividade fí­sica foi realizada através do acelerômetro. As variáveis estudadas neste estudo foram analisadas descritivamente por meio de medidas de tendência central (média e desvio padrão ou mediana, conforme a natureza dos dados), frequência simples e porcentagem. Para comparar a funcionalidade do assoalho pélvico com a atividade fí­sica das idosas foi utilizado o teste ANOVA one-way. O ní­vel de significância adotado foi de 5%. Resultados: As idosas praticam atividade fí­sica em média há 10 ± 9,24 anos, 2 vezes na semana. As medianas dos componentes do assoalho pélvico foram: 3 para força, 2 segundos para resistência, 3 para repetição e 4 para fibras rápidas. Conclusão: Apesar de a força dos MAP ser considerada boa, não há relação entre atividade fí­sica e a funcionalidade do assoalho pélvico.Palavras-chave: assoalho pélvico, atividade motora, idosas.Â

Published: September 2019

An investigation was carried out to assess the extent of ionic toxicity of surface water samples for agricultural usage in the Karatoya-Bangali Floodplain (2,577 sq. km). Fifteen water samples were collected from five industrial areas of Bogura sadar upazila to assess the dissolved chemical constituents and also to classify them on the basis of their comparative stability for agricultural usage. Water samples were collected from surface water sources viz., rivers, canals and ponds at Bogura sadar upazila. The chemical analyses included pH, electrical conductivity (EC), total dissolved solids (TDS), Ca, Mg, K, Na, Zn, Cu, Fe, Mn, Cd, Pb, B, As, CO3, HCO3, PO4, SO4 and Cl. The pH indicated that surface water samples were acidic to alkaline in nature (pH = 6.5-8.8). The electrical conductivity (EC) and sodium absorption ratio (SAR) revealed that all the surface samples were categorized as ‘medium salinity’ and ‘low alkalinity’ hazards with ‘excellent’ and ‘good’ in quality combining expressed as C2S1. Considering TDS all the surface waters were as ‘freshwater’. Soluble sodium percentage (SSP) indicated that all the surface water samples were ‘excellent’ and ‘good’ classes. Residual sodium carbonate (RSC) categorized the surface water samples as ‘suitable’ in quality for irrigation. The status of Ca, Mg, Na, K, Zn, Cu, As, B, Fe, CO3, SO4, PO4, and Cl were not hazards in the investigated area. In all surface water samples, HCO3 ion was considered as pollutant for irrigating crops. Rest ionic constituents were suitable for irrigation purposes. As, B, SO4, Cl and TDS were not problematic for drinking, TDS, Cd, Cu and Zn were not hazardous for livestock usage and SO4 and hardness (HT) were not problematic for aquaculture. But rest ionic constituents for these respective usages were toxic.

The experiment was conducted to evaluate the nutritional and cooking properties of some rice varieties collected from the farmers of Noakhali region of Bangladesh. Noakhali district is situated in the coastal belt of the country and this area also termed as ‘char’ land. All of the selected varieties were grown in saline soil condition. For assessment of nutritional quality, protein, iron and zinc content were estimated. The protein, iron and zinc content ranged from 6.75 to 8.63%, 7.09 to 9.84ppm, 24.52 to 32.34ppm, respectively. The highest amount of protein, iron and zinc were found in Kajalshail variety. All of the rice varieties showed significant variation for all cooking properties studied in this work. The volume expansion ratio (VER) was varied from 1.89 to 2.20. The kernel elongation ratio (KER) was greater than 1.1 in all varieties except Carandol. On cooking Kajalshail variety exhibited highest VER and KER 2.20 and 1.19, respectively. Based on the gel consistency (GC) test, the average GC values ranged from 39.73 to 92.53mm and varieties were categorized as hard, medium and soft. On the basis of alkali spreading value (ASV) the varieties were classified into three groups namely- low, intermediate and high. ASV was found significantly and negatively correlated with gelatinization temperature (GT). The Kajalshail variety was found to have the better nutritional and cooking quality among all varieties.

A comparative study on the costs and returns of organic vs. inorganic farming practices at selected areas near Dhaka, Bangladesh
Authors: Islam Md Arafat , Khan Nazmul Ahsan , Bashar Raisa 
Published: September 2019

Inorganic farming is the norm in most areas of Bangladesh today, especially at croplands near Bangladesh’s capital - Dhaka. However, several recent studies have shown that such practices cause soil degradation overtime, consequently leading to long-term harm to the environment and economic profits. This long-term cost is often avoided by most farmers as inorganic farming is believed to fetch increased productivity/monetary gains, than its environmentally friendly, organic counterpart: the primary aim of this research was to find out the validity of this belief. The research used literature review and analysis of primary data collected about input costs, returns, crop yields, environmental effects, etc., from sixty respondents (mostly farmers and consumers involved in both types of farming), using one-on-one structured interviews, and three focus group discussions at the selected areas of Savar, Sreenagar and Rupganj, focusing primarily on two popular crops – tomato and corn; graphical and tabular analyses were conducted using MS Excel to propose interpretations and record findings. Keeping all other things constant and internalizing environmental externalities, while organic farming was found to produce around 50% and 33% less tomatoes and corns in net terms, respectively, than inorganic farming, the input costs and returns from one cycle of production were found to be lower (50%) and higher (around 200USD), respectively. Hence, from a long-run perspective, organic farming was concluded as the more cost-effective choice both in economic and environmental terms, given that the Dhaka market for organic products are managed better by the producers, consumers and government, alike.

Open Method of Coordination in the European research policy
Authors: Mikita József , Nagy János 
Published: September 2019

Research, development and innovation (R+D) are of great importance nowadays as regards the competetiveness and economic growth of any given country. In the European Union the Lisbon Strategy considers R+D as a crutial means to enhance european competetiveness. The EU is substansially lagging behind its main competitors (USA, Japan) in this domain, furthermore developing countries (China, India) have recently been makinggreat progress, thus posing additional challanges to our continent. The EU needs to assess the present situation as soon as possible and meet the latest challenges in the most efficient way. In order to achieve this objective, the concept of the European Research Area (ERA) has been elaborated with the aim of reorganising, regrouping and integrating existing structures. The open method of coordination (OMC) is playing an important role in the implementation of this common area. It constitutes an alternative policy-making merthod to pure „intergovernmentalism” and the„community method”. The OMC in the field of research policy is coordinated by the Scientific and Research Committe (CREST), which provides a forum for member states to share their experience and reach their common goals.
