Research ArticleOpen accessPhrase in the titleLaboratory Scale of Liquid Coal Fuel Combustion Process and Exhaust Gas FormationKartika Kus Hendratna, Osami Nishida, Hirotsugu Fujita, Wataru HaranoProblem statement: Much research of coal has been already undertaken to ascertain the possibilities of coal being used as substitute for heavy fuel oil in the transportation sector. The effects of using coal as transportation fuel to the environment must also be considered. This study will review several aspects of the coal oil combustion process including combustion behavior, flame stability, … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 6,761 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSimultaneous Thermodynamic and Kinetic Parameters Determination Using Differential Scanning CalorimetryNader Frikha, Mohamed Bouroukba, Eric Schaer, Jean-Leon HouzelotProblem statement: The determination of reaction kinetics is of major importance, as for industrial reactors optimization as for environmental reasons or energy limitations. Although calorimetry is often used for the determination of thermodynamic parameters alone, the question that arises is: how can we apply the Differential Scanning Calorimetry for the determination of kinetic parameters. The objective of this study consists … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 12 Mar 2011 · 7,986 accessesView PDFCite
Research ArticleOpen accessIn the abstractRelationship between Laboratory Germination and Biometric Parameters of Betula jarmolenkoana Golosk. AgletsZhandos Rakymbekov, Kurmankul Abayeva, Daniyar Dosmanbetov et al.This study evaluates the relationship between laboratory germination and biometric parameters of aglets of the critically endangered birch tree species Betula jarmolenkoana Golosk (Yarmolenko birch). The Yarmolenko birch is a very rare, narrowly endemic species, growing at an altitude of 1,900-2,100 m above sea level and only in the basins of three rivers (Kakpak, Bayynkol, and Tekes) in the Almaty … …OnLine Journal of Biological Sciences, Vol. 23, Issue 1 · 1 Mar 2023 · 4,912 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdvanced Assessing Techniques of the Reproductive Performance of BullsGulzat Turysbayeva, Isatay Jakupov, Aisulu Kuzerbayeva, Zhanargul ZharkimbayevaThe sperm quality supplied by producers is an urgent problem in the field of livestock breeding. Therefore, monitoring the health of male producers and sperm quality is of great priority. The study aimed to assess the reproductive performance of bulls using laboratory, clinical, morphological, ultrasound and reflexological techniques. A total of 17 heads of Kazakh-white-headed, Holstein-Frieze and Simmental breeds were … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 1 · 23 Jan 2023 · 5,666 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Culture of Oocytes from Dairy Cows' Ovaries for Productivity in the Southeastern Region of KazakhstanDauren Maratovich Bekenov, Batyrkhan Azimkhanovich Buralkhiev, Yusupzhan Artykovich Yuldashbayev et al.This research work aims to study methods for isolating and culturing follicular oocytes from Holstein cows in vitro. The proven complex of technologies for embryo transplantation on an industrial scale will provide a 3-5-fold acceleration of reproduction of highly productive cows. As a result of scientific research, biotechnological methods of accelerated reproduction of dairy cattle have been substantiated and introduced … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 14 Oct 2024 · 4,298 accessesView PDFCite
Review ArticleOpen accessIn the abstractCurrent Laboratory Biosecurity for Handling Pathogenic VirusesI Made Artika, Chairin Nisa Ma’roefThe recent emergence of lethal viruses such as Ebola raises some concern about the possibility of the viruses being used as biological weapons. The application of pathogenic viruses as biothreat agents in the past is well documented. Although their use in warfare is currently prohibited by the Biological and Toxin Weapon Convention, their potential use in bioterrorism is a global … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 6 Apr 2018 · 10,625 accessesView PDFCite
Research ArticleOpen accessIn the abstractEconomic Evaluation of Streptococcus Pneumoniae Culture MediaVictor Morais, Norma SuárezStreptococcus pneumoniae, a major bacterial pathogen worldwide, requires a complex medium for culture, which complicates harvesting of antigens for vaccine production. Here we present an economic evaluation of factors affecting the production cost of a chemically defined medium for the scale up of fermentation of S. pneumoniae, compared with the most traditional fermentation media. A basic laboratory-scale experiment of 1 … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 2 · 27 May 2016 · 8,374 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimilitude Distortion Compensation for a Small Scale Model of a Knee Braced Steel FrameNouredine Bourahla, Anthony BlakeboroughThe purpose of producing scaled physical models is to allow the assessment in the laboratory of the probable response of a structure to a prescribed loading. It is obviously of paramount importance to construct these models to reflect reality as accurately as possible. The problem encountered particularly for dynamic testing is that the similitude requirements are sometimes impractical. This paper … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 7 Aug 2015 · 7,176 accessesView PDFCite
