Research ArticleOpen accessIn the abstractMOTIONS STUDY OF A SINGLE CYLINDER HIGH SPEED SPARK IGNITION LINIER ENGINE WITH SPRING SYSTEM AS RETURN CYCLEA. Z.M. Fathallah, Semin, I. M. Ariana, I. GeriantoA single cylinder two stroke spark ignition conventional engine have been modified to linier engine with spring mechanism. Before develop the design of linear engine is necessary to analysis of motion. Although principle of combustion process in combustion chamber is the same in fact the oscillation movement is different. Simulation technique has been adopted to study both linear and conventional … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 17 Jan 2014 · 7,184 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Air Pollution on Human Health: Focusing on the Rudnyi Altay Industrial AreaVitaliy G. Salnikov, Marat A. KaratayevProblem statement: Air pollution in Kazakhstan is significant environmental problem. The air pollution level of cities and industrial centers remains rather high. The highest level of air pollution is registered in Ridder, Ust-Kamenogorsk, Almaty, Zyryanovsk, Aktau, Atyrau, Shymkent, Taraz, Petropavlovsk and Temirtau. The enterprises of the Rudnyi Altay, Pavlodar Oblast and enterprises of oil and gas complex in West-Kazakhstan, Atyrau … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 21 Jul 2011 · 10,451 accessesView PDFCite

Research ArticleOpen accessIn the abstractIsolation and Characterization of Chemical Constituents, Cytotoxicity, Antibacterial and Antioxidant Activity of the Compounds from Leptadenia hastata Roots Extract ByIsaac John Umaru, Hauwa A. UmaruThe aim of this work was to extract, isolate and characterise the chemical constituent from Leptadenia hastata roots. Fresh roots were washed and dried and was subjected to sequential maceration in polar and non-polar solvents. And introduced into rotary evaporator to concentrate the extract. Isolated compound was subjected to Thin Layer Chromatography and spectral analysis such as column and UV-Visible … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 4 · 24 Dec 2019 · 7,961 accessesView PDFCite
Research ArticleOpen accessIn the abstractPolycyclic Aromatic Hydrocarbon Accumulation and Biomarker Responses in Cockles from Moroccan Mediterranean CoastsIkram Chbani, Saida Bouzid, Nourredine Bouayad, Hassan Er-RaiouiThis study aims to evaluate levels and effects of Polycyclic Aromatic Hydrocarbons (PAHs) in cockles (Acanthocardia tuberculatae) collected from two differently influenced areas in the Mediterranean Western Moroccan coasts. PAHs accumulation was studied in soft tissues using Soxhlet extraction and separation on silica column methods. The measure of those organic compounds was realized by Gas chromatography coupled to Mass spectrometer … …American Journal of Environmental Sciences, Vol. 15, Issue 4 · 30 Jul 2019 · 7,503 accessesView PDFCite
Research ArticleOpen accessIn the abstractLong Term Ageing Effect on Physical and Shear Strength Characteristics of Oil Contaminated Sandy Soils of Al-Ahmadi Field in KuwaitHumoud Melfi Aldaihani, Fahad A. Al-OtaibiSerious environmental damage was caused to Kuwait when more than 600 oil wells were set alight following the 1991 Gulf War, leading to hydrocarbon contamination and a series of ‘oil lakes’ being created in the desert. The effects of these highly damaging actions are still detectable today, 27 years later. The main contribution of this paper is that the effects … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 1 Apr 2019 · 8,065 accessesView PDFCite
Research ArticleOpen accessIn the abstractContributions to the Stirling Engine StudyFlorian Ion Tiberiu PetrescuIn the process of transforming thermal energy into mechanical work, among the known thermal machines, the Stirling engine is the one that can achieve the highest yield (theoretically up to the maximum yield of the Carnot cycle), although in practice it is reduced by the properties of gas and materials used such as friction coefficient, thermal conductivity, melting point, breaking … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 22 Nov 2018 · 10,178 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Simulation and Optimum Operation Strategy of a Trigeneration System Serving a HospitalFrancesco Calise, Massimo Dentice d'Accadia, Luigi Libertini et al.This paper presents a numerical analysis of a trigeneration system in a hospital, aiming at determining the cost-optimal operating strategy as a function of the energy demands to be matched. The system includes: A natural gas fired reciprocating engine, heat exchangers for waste-heat recovery, a single-stage LiBr-H2O Absorption Chiller (ACH), a cooling tower, pumps, a backup boiler, a backup vapour-compression … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 29 Aug 2016 · 8,183 accessesView PDFCite
