Research ArticleOpen accessEvery word in the titleCharacterization of Household Wastes in D.R. Congo, a Case Study of LubumbashiMartin T. Mpinda, Sissou Zakari, Olusegun K. Abass et al.The insufficient supervision of household solid waste is a notorious problem in DR. Congo cities. Besides, solid waste management in Lubumbashi has been very rudimentary and unsystematic. This study aims to quantify and characterize the household solid waste in two Lubumbashi municipalities. For more than 50 years after independence from colonialism, the city trailed direct discharge of waste on exposed … …American Journal of Environmental Sciences, Vol. 13, Issue 3 · 10 Jun 2017 · 8,217 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMolecular Characterization of Vaccine-Derived Mutants of Avian Metapneumoviruses Isolated from Turkeys in EgyptAbdel-Satar Arafa, Wessam Mady, Ahmed Hussein et al.Avian metapneumovirus (aMPV) causes acute respiratory infection in turkeys with sudden onset and rapid spread in the infected flocks. Vaccinated flocks frequently showed clinical signs typical like the non-vaccinated flocks in Egypt, this situation suggests a virulent vaccine virus was circulating in the field. Oropharyngeal and nasal sinus swabs were collected from 100 turkeys from 10 commercial farms with mild … …Current Research in Virology, Vol. 4, Issue 1 · 12 Aug 2015 · 12,748 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMOLECULAR CHARACTERIZATION AND IMMUNOPROTECTIVE ACTIVITY OF CAPSULAR POLYSACCHARIDE OF KLEBSIELLA PNEUMONIAE ISOLATED FROM FARM ANIMALS AT TAIF GOVERNORATEAhmed M.A. Mansour, Hoda M. Zaki, Nibal A. Hassan, Abdulrahman A. Al-HumianyKlebsiella pneumoniae is a Gram-negative enterobacterium that has historically been and currently remains, a significant cause of human disease and several kinds of infections in animals. In the present work, trials for the isolation of Klebsiella pneumoniae from diseased and apparently healthy farm animals (cows, sheep, goats and camels) were done for recognition of Klebsiella pneumoniae subspecies. It was noticed … …American Journal of Infectious Diseases, Vol. 10, Issue 1 · 6 Jan 2014 · 7,937 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMolecular Characterization of Goats Using Random Amplified Polymorphic DnaNandani Kumari, L. B. Singh, Subodh KumarBlack Bengal goat is a very valuable goat breed in India. The present investigation was proposed to be undertaken to evaluate gene flow, phylogeographic history, genetic structure and differentiation of both the goat populations to study genetic variation prevailing among Black Bengal and Black Bengal type goat in west Bengal and Jharkhand respectively and to study genetic relationship between both … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 1 · 20 Feb 2013 · 7,846 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHealth Impacts Estimation of Mineralogical and Chemical Characterization of Suspended Atmospheric Particles over the East DesertU. Ali Rahoma, Elsayed EmaraProblem statement: The small size fraction of aerosols, measured as PM10 and PM2.5, rather than the larger particles, is considered to be responsible for most of the health effects. Such particles have a relatively long residence time in the atmosphere and can therefore travel over long distances. Hence, a large portion of ambient concentrations of PM10 and in particular of … …American Journal of Infectious Diseases, Vol. 6, Issue 3 · 30 Sep 2010 · 10,772 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWaste Characterization in Steel Casting and Recycling Opportunities in EuropeSilvia Fiore, Maria Chiara Zanetti, Barbara RuffinoThe wastes coming from a steel foundry located in Italy, producing about 600,000 t/y of steel slabs, are considered in this work. The plant produces about 143,000 t/y of wastes, made of furnace and ladle slags (84%), pelletized dust (8%) and oxidised shaving (8%). The waste materials have been characterised by means of particle-size and chemical analyses, and some reuse/recycle … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,049 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMolecular Characterization of Black Bengal and Jamuna Pari Goat Breeds By RAPD MarkersM.A. Rahman, S.M.M. Rahman, M.A. Jalil et al.This experiment was conducted in the Genetics, Breeding and Reproductive Biotechnology Laboratory under Goat and Sheep Production Research Division, Bangladesh Livestock Research Institute (BLRI), Saver, Dhaka, Bangladesh. DNA was extracted from 14 goat breeds and the extracted DNA was observed by gel electrophoresis. Eight goat specific primers were synthesized by ASM-800 DNA synthesizer and screened in the study and all … …American Journal of Animal and Veterinary Sciences, Vol. 1, Issue 2 · 31 Dec 2006 · 9,584 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Novel Characterization of the Incidence Term in Epidemic Models: Interpretation of the Resulting Basic Reproduction Number in Terms of Healthcare AccessibilityFrancis BenyahWe propose a novel characterization of the incidence term in mathematical epidemic models. This new characterization takes into consideration the fact that at any given time, only a proportion $\kappa \ (0 \, \le \, \kappa \, \le \, 1)$, of infectives have access to healthcare. Infectives without access remain untreated and therefore, become reservoirs for new transmissions.The proposed incidence … …Journal of Mathematics and Statistics, Vol. 22, Issue 1 · 1 Oct 2026 · 582 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn-Farm Phenotypic Characterization of Sheep Breeds in BotswanaKaelo Pelotshweu, Monosi Andries Bolowe, Nicodemus Pungi Mosweu et al.Phenotypic characterization data serve as a baseline for the evaluation of the effectiveness of selection programs and the development of conservation strategies. Therefore, this study aimed to phenotypically characterize Tswana, Dorper, Damara, Meat-master, and Karakul sheep breeds in Botswana under a ranch management system. Qualitative and quantitative data was collected from 595 adult sheep (one year and above). Data on … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 1 · 1 Mar 2025 · 7,311 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIsolation and Characterization of Superior Symbiotic Bacterial Isolates from the Oenggae Sea with Potential as AntibacterialLukas Pardosi, Adelya Irawan Manalu, Charles Venirius LisnahanSponges are one of the marine biota that have a symbiotic relationship with bacteria which can produce secondary metabolites as antimicrobials. The main aim of this research was to isolate and identify bacteria that had potential as antibacterials against multi-drug resistant test bacteria. The sponsor samples used in this research were Stylissa massa, Salvador Dali, and Angelas sp.
