Large eddy simulation of plume dispersion behind an aircraft in the take-off phase

The aim of this paper is to provide an investigation, using large eddy simulation, into plume dispersion behind an aircraft in co-flowing take-off conditions. Validation studies of the computational model were presented by Aloysius and Wrobel (Environ Model Softw 24:929–937, 2009) and a study of the flow and dispersion properties of a double-engine aircraft jetwas presented by Aloysius et al. EEC/SEE/2007/001,EUROCONTROLExperimentalCentre, http://www.eurocontrol.int/eec/gallery/content/public/document/eec/report/2007/ 032_ALAQS_comparison_of_CFD_and_Lagrangian_dispersion_methods.pdf), in which only the engine was modelled. In this paper, the complete geometry of a Boeing 737 is modelled and investigated. The currentwork represents a contribution towards a better understanding of the source dynamics behind an airplane jet engine during the take-off and landing phases. The information provided from these simulations will be useful for future improvements of existing dispersion models

Imperatives of Legislative Oversight Function in Nigerian Democratic System

This study aims to identify and analyze the role of economic growth on poverty reduction seen from sectors in 2004-2012. The variables used were the number of poverty as the dependent variable and the Gross Regional Domestic Product (GRDP) in nine sectors as independent variables. The data used in this research is secondary data obtained from the data published by the World Bank. The analytical method used is the panel data regression with fixed effect model approach. In processing the data, the authors using statistical software Eviews 8.1.Based on estimates obtained that overall economic growth is negative and have significant effect on poverty at the provincial level in Indonesia. Furthermore, in terms of sectoral found that variable per-mining sector has a negative influence and significant impact on poverty reduction. It was caused by the commodities boom of the commodity mined.

Pemanfaatan Drosophila Melanogaster Sebagai Organisme Model Untuk Mempelajari Pengaruh Faktor Lingkungan Terhadap Ekspresi Sifat Makhluk Hidup Pada Perkuliahan Genetika

The interaction between genetic and environmental factors in determining the characters of living organism is one of the main concepts in biology nowadays, and it becomes one of the main topic that students learn in genetics lecture. However, the observation result showed that regulation of gene expression in eukaryotes was considered to be a quite difficult topic for the students. The utilization of Drosophila melanogaster through practical activities can be used as an instructional media to help students understand the effect of environmental factors on the characters of living organism. This research aims to prove that through the crossbreeding of D. melanogaster for several generations, the effect of environmental factors on the characters of living organism can be observed. In this research, three strains of D. melanogaster were used to reveal the effect of dark environment on fecundity, which is one of the determinant factors of fitness in insects. The results showed that D. melanogaster treated in dark condition had lower fecundity than that in the control condition. The results of the comparison among the strains also showed that the strains of wild-type had higher fecundity than the white eyed color and ebony strains. The interaction between light conditions and generation and the interaction between light, strains, and generation also had an effect on the fecundity
