Research ArticleOpen accessIn the keywordsThe Effect of Rapid Thermal Annealing Towards the Performance of Screen-Printed Si Solar CellShahrul Anizan, Cheow Siu Leong, Khairymaza Lee Yusri et al.Problem statement: Solar cells are used to capture the photons which generate the energy. However the efficiency of the cells to turn the amount of photon to electricity needs to be high and so the cells enhancement is needed. This involved the whole process of the developing of the cells, thus annealing process is one of the important steps that … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,224 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Polishing of Cutting-Edge Polymer-on-Glass for Pigtailing PreparationMohammad Syuhaimi Ab-Rahman, Fazlinda Ab-Aziz, Noor Azie Azura Mohd Arif et al.Problem statement: The high quality of cutting-edge surface is important in optical waveguide's efficiency. The perfect polishing of end surface is significant to deliver the best quality of light waves and minimize the device losses such as insertion loss and return loss. Hence, this research is concern on the parameters in polishing SU-8 polymer to increase the efficiency of waveguide. … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 9,148 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvolution of Microbial Biomasses C and N during the Composting of Municipal solid WastesOlfa Fourti, Naceur Jedidi, Abdennaceur HassenProblem statement: The aim of this study was mainly focused on the evolution of microbial biomasses C and N during the composting of municipal solid wastes. Approach: The carbon and the nitrogen of the microbial biomass (BC and BN) were studied using the fumigation-extraction method. Results: The dynamics of the BC/BN ratio, index of the chemical composition of the whole … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 6,702 accessesView PDFCite
Research ArticleOpen accessIn the abstractCyclodextrin Glucanotransferase Activity of Microbial Strains Isolated from Yam-Cultivation Soils in Northwestern BeninCyrille Alode Vodounon, Ténor Dias-Mendel Allode et al.β-Cyclodextrin, an industrially important oligosaccharide, is produced by microbial enzymes such as cyclodextrin glucanotransferase (CGTase). This study investigated ways to optimize the enzymatic activity of CGTase from Bacillus cereus, Bacillus pumilus, Bacillus brevis, and Bacillus subtilis strains isolated from soils in north-western Benin. Cyclization activity of CGTase and the influence of pH, temperature, and metal ions were assessed using conventional … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 21 Sep 2026 · 652 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal Inactivation and Kinetic Characterisation of Peroxidase from Leaves of Brassica chinensis L.Youru Huang, Keyu Rong, Shiman Zhao et al.As one of the perennial vegetable varieties grown in the south of Yangtze River in China, Brassica chinensis L. can be produced and supplied to the market all year round and has high economic value. However, there is little direct literature on postharvest heat treatment of Brassica chinensis L. In this study, Peroxidase (POD) was extracted from Brassica chinensis L. … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 2 · 12 Jul 2024 · 4,768 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphological and Structural Reaction of Avena sativa Seedlings to the Effects of Nano and Microparticles of ZincArailym Serikbai, Aidar Aitkulov, Anna Stanco et al.Kazakhstan has a well-developed mining and metallurgical industry, which produces macroand nanoparticles of heavy metals, including zinc emitted to the environment. The nanoscale particles have a different biological activity, which requires some additional research. The effects of various concentrations of zinc macroparticles and nanoparticles on the anatomical structure of oat seedlings (Avena sativa L.) and their accumulation in vegetative organs … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 9 Jul 2024 · 4,406 accessesView PDFCite
Research ArticleOpen accessIn the abstractMaximizing Fungal Growth in State-of-the-Art Tray Solid-State Fermenter: Aeration Strategies Optimized for Enhanced PerformanceMusaalbakri Abdul Manan, Colin WebbThis study introduced a tray fermenter, featuring eight layers of squared perforated trays, specifically designed for solid-state fermentation applications. It is named the multi-layer squared tray solid-state fermenter. The fermenter employs two aeration strategies with varying air flow rates to optimize fungal growth. Firstly, sterilized moistened air at 8 L/min flows from the bottom through the perforated trays. Secondly, a … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 9 Apr 2024 · 6,453 accessesView PDFCite

Zhumataуeva, Bakhytzhan A. Duissembekov, Yerlan Dutbayev et al.The purpose of the study was to perform genetic identification of the strains of fungi of the Beauveria genus and evaluate the effect of abiotic factors on the growth and survival of colonies and the productivity of conidia of these fungi, as well as to determine the biological effectiveness of the semi-preparative form of the drug based on Beauveria bassiana … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 22 Nov 2022 · 5,702 accessesView PDFCite
Research ArticleOpen accessIn the abstractGermination Study and Monitoring in the Nursery of Young Seedlings of Garcinia mangostana L.Haba Jean Florent, Dembele Ardjouma, Koffi Kouao Jean et al.Mangosteen tree (Garcinia mangostana L.) is a plant of the Clusiaceae family cultivated for its particular taste and for its excellent medicinal properties. However, the vegetative propagation of the plant by cuttings or grafting being difficult to achieve, seed germination remains the main means of production used. This study was therefore initiated with the aim of determining the influence of … …American Journal of Agricultural and Biological Sciences, Vol. 16, Issue 1 · 23 Sep 2021 · 7,440 accessesView PDFCite
