Research ArticleOpen accessIn the author namesTowards the Efficiency of Municipal Solid Waste Management in the Democratic Republic of Congo (DRC): Case Study of LubumbashiMartin T. Mpinda, Olusegun K. Abass, Mujinya B. Bazirake et al.This paper provides an overview on the state of Municipal Solid Waste Management (MSWM) in Lubumbashi, D.R Congo. To meet the recently proposed Sustainable Development Goals (SDGs), establishment of efficient waste management techniques and strategies geared towards monetizing waste in the framework of sustainable growth is inevitable. Solid waste categorization and collection in conjunction with recycle, reuse and revalue are … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 27 May 2016 · 10,157 accessesView PDF Cite

Research ArticleOpen accessIn the author namesEarly Universe in the SU(3)L⊗U—(1)X Electroweak ModelsHoang Ngoc LongWe present status of the 3-3-1 models and their implications to cosmological evolution such as inflation, phase transitions and sphalerons. The models can deal not only with the issues such as neutrino physics, dark matter, etc, but they are also able to provide quite good agreement with the Standard Cosmology: The inflation happens at the GUT scale, while phase transition … …Physics International, Vol. 7, Issue 1 · 13 Nov 2015 · 7,938 accessesView PDF Cite

Research ArticleOpen accessIn the author namesEFFECT OF DIMETHOATE (AN ORGANOPHOSPHATE INSECTICIDE) ON THE REPRODUCTIVE SYSTEM AND FERTILITY OF ADULT MALE RATFerdinand Ngoula, Pierre Watcho, Augustave Kenfack et al.The pesticides are one of the most potentially harmful chemicals liberated in the environment in an unplanned manner. Dimethoate is widely used as a potent pesticide in many countries and has been shown to produce some adverse health effects. In the present study, we investigated the effect of dimethoate (an organophosphate insecticide) on the reproductive system and fertility of male … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 1 · 13 Feb 2014 · 8,598 accessesView PDF Cite

Research ArticleOpen accessIn the author namesLithofacies and Depositional Environment of Volcano-Sedimentary Deposits of Se Mayo Oulo BasinElie Fosso Menkem, David Sebag, Benjamin Ngounou Ngatcha, Alain DurandThe study of volcano-sedimentary deposits of Mangbai in SE Mayo Oulo basin-Cameroon leads to the identification of five major distinct lithofacies types. From the coarset to the finest lithofacies, there are: Gb-clast supported by massive coble and boulder, Gg-granule to massive gravel, Sm-massive sand, Sh-horizontal layered sandstones, Fml-massive laminated claystones. Coarse facies (Gb, Gg, Sm) are cemented with volcanic matrix … …Current Research in Geoscience, Vol. 3, Issue 2 · 19 Dec 2013 · 7,375 accessesView PDF Cite

Research ArticleOpen accessIn the author names3D Modelling for Mechanized Tunnelling in Soft Ground-Influence of the Constitutive ModelNgoc-Anh Do, Daniel Dias, Pierpaolo Oreste, Irini Djeran-MaigreThe main purpose of this study was to provide a three-dimensional numerical model which would allow to show the influence of the constitutive model of the ground on the tunnel lining behaviour and displacement field surrounding the tunnel. Most of the processes that occur during mechanized excavation have been simulated in this model. Besides the well-known elastic linear perfectly plastic … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 8,377 accessesView PDF Cite

Research ArticleOpen accessIn the author namesBacteriological Examination of Computer Keyboards and Mouse Devices and Their Susceptibility Patterns to DisinfectantsOnochie Charles Chimezie, Anyim Chukwudi, Alo Moses Nnaemeka et al.Computers are ubiquitous and have been shown to be contaminated with potentially pathogenic bacteria in some communities. There is no economical way to test all the keyboards and mouse out there, but there are common-sense ways to prevent bacterial contamination or eliminate it if it exists. In this study, swabs specimens were collected from surfaces of 250 computer keyboards and … …Current Research in Microbiology, Vol. 4, Issue 1 · 19 Jan 2013 · 13,518 accessesView PDF Cite

Research ArticleOpen accessIn the author namesPrevalence of Drug-Resistant Strains of Streptococcus Pneumoniae in AbakalikiIroha Ifeanyichukwu Romanus, Okafor Florence Njideka, Nwakaeze Emmanuel Amobi et al.Streptococcus pneumoniae is a major cause of illness such as pneumonia, meningitis, bacteremia and otitis media in children and the elderly. The emergence of drug-resistant strains threatens to complicate the management of these diseases. We conducted a hospital-based surveillance for drug-resistant Strep. Pneumoniae in outpatients with pneumococcal infection in Abakaliki Ebonyi State Nigeria. Between 2003-2005 from January through December, a … …American Journal of Infectious Diseases, Vol. 8, Issue 3 · 26 Nov 2012 · 7,680 accessesView PDF Cite

Approach: Concentrations of 23 trace elements and stable isotope ratios (δ13C and δ15N) were analyzed in suspended particulate matter, one species of peanut worm, … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 9 Mar 2012 · 7,805 accessesView PDF Cite

Research ArticleOpen accessIn the author namesKinetic Optimization of Folic Acid Polymer Conjugates for Drug TargetingJacob M. Ngoy, Sunny E. Iyuke, Clarence S. Yah, Wilhelm E. NeuseProblem statement: Folic Acid (FA) is an essential, bioavailable water soluble B-complex vitamin that helps in the replication of normal cells. It is obtained from natural sources and it deficiency can leads to oncogenic cells development. Within this frame work in mind, we designed and synthesized a new bioconjugate carrier that can enhance the effectiveness of FA. Approach: The polymeric … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 7,110 accessesView PDF Cite
