Research ArticleOpen accessAll words, across the recordIn vivo Efficacy of Murraya paniculata Leaf in Controlling Natural Helminthiasis in GoatDuangjai Boonkusol, Janejira Detraksa, Kansuda Duangsrikaew, Wuttipong TongbaiThis study investigated the in vivo effect of Murraya paniculata leaf on gastrointestinal nematodes reduction, growth rates and haematological changes of goats. Four experimental groups (n = 6) of goats naturally acquired gastrointestinal nematodes were control (GI) (untreated), positive control (GII) (treated with albendazole, 6 mg/Kg BW) and GIII and GIV treated with 5 and 10 g/Kg BW of M. … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 2 · 1 May 2019 · 7,703 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExperimental Study on the Microbial Community Structure of the Sediment of Pi River under the Different pH in WinterCairui Yu, Dongmei Shen, Wanfeng Wang et al.In order to solve the poor self-purification ability of low temperature water in winter, the microbial community structure in the sediment of Pi River water (located in West Anhui) was investigated experimentally in this study. Firstly, the sediment was sampled in the lower reaches of Pi River and prepared with the different pH (5.0, 5.5, 7.0 and 8.5); secondly, the … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 15 Mar 2021 · 6,129 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordComparing SMarty and PLUS for Variability Identification and Representation at Product-Line UML Class Level: A Controlled Quasi-ExperimentAnderson S. Marcolino, Edson OliveiraJrAlthough variability management is one of the main activities of software product lines, current literature provides almost no empirical evaluations on variability management approaches based on UML. This paper aims at experimentally comparing two approaches and picks SMarty and PLUS as representative examples. Such comparison takes into account their effectiveness of expressing correctly and incorrectly variabilities in UML class diagrams. … …Journal of Computer Science, Vol. 13, Issue 11 · 9 Nov 2017 · 7,462 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExperimental Evaluation of the Raking Energy in Damping System of Steel Stud Partition WallsSalah Amer, Sameer Hamoush, Taher M. Abu-LebdehNonstructural partition walls are usually specified based on the best practice without any structural design calculations. However, given the likely severe earthquake damage to nonstructural components and the substantial cost of repair to such components, it is imperative that we develop an understanding of the seismic response of the nonstructural partition walls when subjected to earthquake loading conditions. The main … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 6 Nov 2015 · 7,644 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExperimental Investigation on Performance and Emission Characteristics of Low Heat Rejection Diesel Engine with Ethanol as FuelP. Lawrence, P. Koshy Mathews, B. DeepanrajProblem statement: Depleting petroleum reserves on the earth and increasing concerns about the environment leads to the question for fuels which are eco-friendly safer for human beings. The objective of present work was to investigate the effect of coating on piston, cylinder head and valves of a Diesel engine on the performance and emission characteristics of exhaust gases using wet … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,224 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBackscattered Acoustic Energy by Monobubbles Experimental Approach and Statistical Study of the AttenuationAli Khelil, Claude ManteProblem statement: As the number of air bubbles in the sea is very high, they are so many acoustic diffusers who make illegible the recordings the purpose of which is to quantify the alive bodies. The signals backscattered by air bubbles constitute a parasite in offshore recordings and must be eliminated. It is planned to finalize techniques allowing the localization … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,585 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExperimental Investigation of Limonene-based Environmental-Friendly Emulsion Drilling MudOlaitan Oluwaseum Micheal, Orodu Oyinkepreye David, Ehinmowo Adegboyega BoluThe use of emulsion drilling mud in the oil and gas industry has gained wide acceptance. However, the disposal of drill cuttings and the waste of such emulsion drilling mud usually poses environmental concern. Hence, there is the need to seek oil from biodegradable sources as an alternative to the current conventional diesel oil which constitute environmental threat. In this … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 12 Jun 2017 · 7,926 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBehavior of Lightweight Coarse Aggregate RC Beams with Circular OpeningAdel A. Al-AzzawiThis pressent research investigates the mechanical properties of Waste Rubber Fibers Lightweight Coarse Aggregate Concrete (WRFLWAC) mixture. Also, the shear behaviors of 12 RC beams contain opening are investigated. The main study parameters are: The opening location, the waste rubber fiber ratio and the shear reinforcement. Deflection values and cracks are registered at each load step; also the cracking or … …American Journal of Applied Sciences, Vol. 14, Issue 4 · 1 Apr 2017 · 7,460 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExperimental Study of Composite Beams Made of Steel Tubes Filled with Concrete under the Confinement Effect of U-Links and Stud-PlateMoayyad Al-Nasra, Madiha Ammari, Taher Abu-Lebdeh, Abdelqader NajmiConcrete strength improved substantially when lateral confinement stresses are provided. This effect has been exploited in this study in composite beams at the concrete compression zone. New type of confinement is used in this research. The confinement of concrete in the compression zone is accomplished by providing U-links and stud-plate systems. The U-links are steel bars in the shape of … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 20 Mar 2017 · 7,265 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNitric Oxide Donors with Therapeutic Strategic in Experimental Schistossomiasis MansoniWander Rogério Pavanelli, Jean Jerley Nogueira da Silva, Carolina Panis et al.Schistosomiasis, an immune disease, remains a major public health problem in endemic area. To determine the influence of Nitric Oxide (NO) on this disease, we tested two compounds (Trans-[Ru(bpy)2(NO)SO3](PF6)-PF6 and Na2[Fe(CN)5(NO)]-SNP, which releases NO when activated by biological reducing agents, in BALB/c mice infected subcutaneously by Schistosoma BH strains. The parasitic activity of NO-donors was evaluated in this model by … …American Journal of Immunology, Vol. 10, Issue 4 · 24 Feb 2015 · 7,852 accessesView PDFCite
