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, Imperatives of Legislative Oversight Function in Nigeria Democratic System examines the strength and level of separation of powers, among the three tiers of government, the autonomy, checks and balances among the arms.

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. So that the mining sector is not a sector that is key in reducing poverty, but the commodities boom have an impact on poverty reduction in the province in Indonesia

Analisis Survival pada Pasien Penderita Sindrom Koroner Akut di RSUD Dr. Soetomo Surabaya Tahun 2013 Menggunakan Regresi Cox Proportional Hazard

Berdasarkan diagnosis dan gejala, estimasi jumlah penderita Penyakit Jantung Koroner (PJK) terbanyak di Indonesia adalah Provinsi Jawa Timur sebanyak 375.127 orang (1,3%). Diantara beberapa diagnosis, jenis PJK yang paling berbahaya adalah Sindrom Koroner Akut (SKA) karena dapat menyebabkan kematian dalam waktu 15 hingga 30 menit sejak serangan nyeri pertama. Oleh sebab itu, penanganan pasien SKA harus secepat mungkin dengan selalu memperhatikan laju perbaikan klinis pasien. Dengan demikian, perlu dilakukan penelitian mengenai faktor-faktor yang mempengaruhi laju perbaikan klinis pasien SKA di RSUD Dr. Soetomo Surabaya. Salah satu analisis statistika yang dapat digunakan untuk menjawab tujuan tersebut adalah analisis survival dengan model regresi Cox Proportional Hazard. Analisis survival merupakan suatu metode statistik dimana outcome variabel yang diperhatikan adalah waktu hingga terjadinya suatu kejadian (event) atau sering disebut waktu survival, sedangkan regresi Cox Proportional Hazard merupakan salah satu regresi semiparametrik dimana variabel responnya berupa waktu survival. Setelah dilakukan analisis, diperoleh kesimpulan pada hari ke-5 hingga hari ke-10 peluang pasien tidak mengalami perbaikan klinis cukup kecil. Beberapa faktor yang mempengaruhi laju perbaikan klinis pasien SKA adalah status penyakit dislipidemia, diabetes melitus, hipertensi dan profil hemodinamik. Dan laju perbaikan klinis pasien SKA semakin meningkat dari hari ke-0 hingga hari ke-8, kemudian konstan pada hari ke-8 hingga hari ke-11, lalu turun setelah hari ke-11
