The study of agricultural wastes into biomass is an approach on the way to the growth of alternative energy sources. Artocarpus Heterophyllus Leaves (AHL) powder can be utilized as an alternative energy source to coal. Densification of scum’s depends upon its physical properties and process parameters. In this article the influence of Moisture Content (MC) and Die Pressure (DP) on Relaxed Density (RD) of AHL Powder were studied. The investigation was carried out to explore the properties of fuel briquettes manufactured from AHL. The investigation on scientific model for a synthesized assessment was reputable according to response surface methodology (RSM). Based on the RSM, a most favorable method was preferred for a completely operational AHL briquette utilizing central composite design. ANOVA is utilized to find out the significant factor that influencing the relaxed density was die pressure compared to that of moisture content. From the numerical optimization, the ramp graph exposed that samples are effectively compressed at the pressure of 30.18 MPa and the moisture content of 17 % with relaxed density 733.075 kg/m3 and some useful conclusions were made.

In this work, fast neutron and gamma ray shield attenuation parameters have been calculated for new composite paste shielding with seven different concentrations of high-density polyethylene (HDPE) and borax (BX) that are mixed with cement and sand. Computer program WinXCom has been used to calculate the total mass attenuation coefficients (µ/ρ) for gamma rays at energies from 0.01 MeV to 100 MeV. In addition, the fast neutron removal cross-sections (ΣR) are calculated using the cross-section database for used elements in the composites. The obtained results are used to calculate half value layer (HVL) and relaxation length (λ) as well. The calculated results were compared with experimental results and with all available concrete shields in literature. A reasonable agreements are found which indicated that the composite of 12.5% HDPY, 37.5% BX, has the most significant effect on dose rate reduction and has higher radiation attenuation parameters for neutron and gamma rays. In addition, this composite has the lowest thickness over all available shields, which 10 cm from this composite can attenuate 89 % of neutrons and gamma rays.

Abstract:\n\nThis study designed for evaluating the antibacterial effect of some herbal plant extracts against E.coli. The broth microdilution method used to determine the Minimal Inhibitory Concentrations (MIC) of the studied extracts. Methanol extraction method applied for Moringa oleifera leaves, Cucurbita pepo fruits, Cucurbita pepo seeds, Citrillus colocynthis seeds and Citrillus colocynthis fruits. After fractionation of these crude extracts, we found that, all methanolic extract of these plants had antibacterial effect on E.coli at MIC 640 μg/ml.On the other hand hexane extract of Moringa oleifera leaves, Cucurbita pepo fruits, Citrillus colocynthis seeds and Citrillus colocynthis fruits didn’t show any inhibitory zone for E.coli except Cucurbita pepo seed extract showed inhibition for E.coli at MIC 640 μg/ml. Choloroform extract of Moringa oleifera leaves, Cucurbita pepo seeds, Citrillus colocynthis fruits and Citrillus colocynthis seeds showed inhibition for E.coli at MIC 640 μg/ml, but the chloroform extract of Cucurbita pepo fruits didn’t show any inhibitory zone for E.coli. Also, we found that butanol extract of Moringa oleifera leaves showed inhibition for E. coli at MIC 1230 μg/ml while that of Cucurbita pepo fruit, Cucurbita pepo seeds, Citrillus colocynthis fruits and Citrilus colocynthis seeds had effects on E. coli at MIC 640 μg/ml.These results confirm the traditional claims and provide promising base line information for the potential use of the tested extracts in the fight against bacterial infections.

Based on Maslow’s hierarchy, a human has seven basic human needs, and one of them is love. Love is when a human has passionate affection for a person. Two basic feelings are attached to love: romantic and broken heart feelings. Romantic love can make breakups and will be followed by symptoms of heartbreak. Love has become an important topic of study in neurobiochemical science because love can influence the neuroendocrine system and trigger the release of hormones and neurotransmitters. This work aims to review hormonal and neurotransmitter changes that occur during falls in love and has a heartbreak. The role of hormones and neurotransmitters including their advantages and disadvantages will be discussed in this paper.

In this paper, we use for the first time the GARCH-DECO (1,1) to investigate empirically the dependence between S&P500; index and the sixteen selected S&P GSCI commodities index. We employ daily prices of S&P500; and S&P GSCI commodities indices over the period from January 01, 2003 to December 31, 2015. From the empirical results, the conditional dependence between S&P500; and S&P GSCI commodities indices demonstrate the presence of highly volatility and validate the existence of a greatly time-varying variance in the dynamic equicorrelation between time serie returns obtained after the estimation of the GARCH-DECO (1,1) model. Besides, the conditional heteroscedasticity volatility prediction attains their maximum after the financial crisis of 2007, especially on both years 2008 and 2009. Our empirical finding indicates the existence of highly dependency between S&P500; and S&P GSCI commodities indices which prove the financialisation of US stock market indices and commodities.

The conceptual model of multimedia-based learning communication training to improve the competency in Islamic boarding schools is a process to increase, enhance, and intensify the mudarris capabilities in order to achieve the success of the learning process in Islamic boarding schools. Competencies improvement in this case is an effort to increase the degree, level, quality and quantity, addition of skills and abilities of mudarris to be better in accordance with the expected competency standards. The purpose of this study was to formulate a conceptual model of multimedia-based learning communication training in improving the competence of mudarris Islamic boarding schools.

Therefore, the results of this study can help various parties in improving the competency of Islamic Boarding Schools.

This article explores the various concepts, trends and definitions of urban design that exist in different countries today, as well as the problems associated with the lack of a single theoretical and methodological approach to urban design. It is in the value orientations that the differences in many concepts are most clearly manifested. We show that these contradictions can be solved by expanding the problem field of urban design by incorporating environmental, anthropological and psychological issues to create innovative design projects. There was a need for a comprehensive approach to this subject, taking into account the problem of a holistic understanding of the individual in the unity of life. To this end, we propose a framework that summarizes key contemporary scientific and applied points of view. In this structure links coincidences and complementarities between different conceptual approaches are defined, the focus is on person-centered design. The article reveals the factors of a favorable urban environment for finding a person in it. The methodology of design a favorable combined environment of a modern city is presented. Such an environment is oriented to the simulation of a virtually new synthetic medium with enhanced comfort indicators without detriment to the natural background of the Earth. The relevance of this approach is due to the widespread opinion that it is impossible to achieve ecological balance within the urban settlement. The article examines the strategy of urban open spaces, offers categories and concepts of design-project, reflecting the environmental values of the urban environment.

In this paper, multilevel generalized assignment problem (MGAP) with binary variables is presented. We introduce an approach to solve MGAP with rough interval programming. In this approach the rough interval MGAP is divided into two interval MGAPs. The first interval problem represents the upper approximations of rough intervals and the second represents the lower approximations of rough intervals. The solutions of these two problems will be defined. To demonstrate the effectiveness of the present approach, we introduce a numerical example. A comparison study with the obtained results of [14] who used 0-1 integer interval number programming approach will be introduced.
