Further Aspects of Weak Interaction Dynamics

Eliahu Comay
This work discusses properties of a recently published weak interactions theory which is derived from a Lagrangian density Lw. This theory depends on the experimentally confirmed massive neutrino. The interaction which is carried by an appropriate mediating field is consistent with the Fermi coupling constant of weak interactions GF

Economically Deprived and Marginalized Scholars: Their Lifestyles, Experiences, Challenges and Aspirations

Bernardo A. Zabala, Manuela P. Gutierrez
Ambitious graduating secondary school students who belong to the marginalized sectors of the society apply to become scholars. The study focused on discovering the lifestyles, experiences, challenges and aspirations of the economically deprived and marginalized scholars who enrolled at Nueva Ecija University of Science and Technology System for A.Y. 2014-2015. Ten respondents who met the criteria were cho

The Effect of Different Wavelength of Light for Microbial Fuel Cell with an Anode of Rhodopseudomonas faecalis (PSB-B)

Guang Rong, Qingping Hu
A microbial fuel cell (MFC) with an algae-assisted cathode is a low-cost and sustainable way to provide the oxygen for the oxygen reduction reaction. The anode was with anaerobic microorganism, a kind of photosynthetic bacteria (PSB-B). An algae bioreactor was connected to cathode microbial fuel cells to increase power generation by supplying more oxygen to cathode electrode. In this study, we

Epidemiologic Aspects of Atrial Fibrillation in a Tertiary Hospital in a Sub-Saharan Africa Setting

Félicité Kamdem, Ba Hamadou, Marius Kamdem, Christ Nadège Nganou, Anastase Dzudie, Yves Monkam, Samuel Kingue
Background: Atrial fibrillation (AF) is the most frequent sustained arrhythmia. The prevalence is increasing with that of other cardiovascular risk factors in our low-income setting. It is potentially serious due to the associated complications. Few data exist on the epidemiology of AF in Sub-Saharan Africa (SSA). Methodology: We carried out a cross-sectional study between 2005 and 2009 in the Cardiology Unit of the Douala General

Association between Anthropometry, Dyslipidaemia and the Ten-Year Relative Risk of Cardiovascular Disease in Ghanaians with Type 2 Diabetes and Hypertension at the Battor Catholic Hospital

Sylvester Yao Lokpo, William K. B. A. Owiredu, James Osei-Yeboah, Christian Obirikorang, Margaret T. Agyei-Frempong
Disordered body fat distribution and plasma lipid levels promote atherosclerosis, a major risk factor for cardiovascular disease (CVD). The process of atherosclerosis is vigorous and rapid in diabetes and hypertension. This study sought to determine the relationship between anthropometric and dyslipidaemic parameters as well as ascertain using the Framingham percentage risk for heart disease, the ten-year relative risk of developi

Hot Rolling of Large Gears

Dirk Landgrebe, Andreas Sterzing, Mike Lahl, Thomas Druwe, Anne Manuela Taubert
Forming processes are generally characterized by a high degree of material utilization as well as short process times and, consequently, a decent economic efficiency. Furthermore, incremental forming enables the use of relatively low forming forces which results in a more compact design of the used machines. These conveniences are utilized in terms of roll forming with round tools to form gears and thread

An Informational Proof of H-Theorem

Vincenzo Manca
After a historical reconstruction of the main Boltzmann’s ideas on mechanical statistics, a discrete version of Boltzmann’s H-theorem is proved, by using basic concepts of information theory. Namely, H-theorem follows from the central limit theorem, acting inside a closed physical system, and from the maximum entropy law for normal probability distributions, which is a consequence of Kullback-Leibler entropic divergence positivity

Elaboration of Division—A Systematic Search for True Digits

Milosav M. Marjanovic
In this paper, a new procedure of division is proposed and the corresponding didactical elaboration is sketched. A division task A:B is called canonical when A is less than tenfold B

Comparative Study between Physical Properties of Virgin Oil and Re-Refining Oil

Bestoon M. Faqi-Ahmed, Karzan A. Omar
The lubricating oils are essential for operating engine with high efficiency. Therefore, the physical properties of oil such as flash point, pour point, kinematic viscosity, specific gravity and the American Petroleum Institute are necessary to be studied to indicate good quality of the lubricating oil. In this study, we compare the physical properties of two virgin oils with re-refining oil.

Evaluating the Impact of Routing on QoS of VoIP over MANET Wireless Networks

Azeddien M. Sllame
In this paper, a performance analysis study for VoIP over mobile wireless ad hoc networks (MANET) is carried out using OPNET tool. The AODV, DSR, TORA, OLSR, and GRP routing protocols have been used as candidates to evaluate the impact of routing on quality of service (QoS) of VoIP application over MANET networks. Three different queuing mechanisms (FIFO, PQ, and WFQ) have been used also as nominee of queuing techniques. The VoIP
