Research ArticleOpen accessPhrase in the titleImmobilization of Lipase from Candida Rugosa on Palm-Based Polyurethane Foam as a Support MaterialRoila Awang, Mohd Rafaei Ghazuli, Mahiran BasriLipase from Candida rugosa was immobilized onto palm-based polyurethane foam (PU), which the polymer was pre-soaked in co-immobilized agent. The activities of PU-immobilized lipase were tested by the esterification reaction of oleic acid and oleyl alcohol in hexane. The PU-immobilized lipase was then characterized in term of its thermal, operational and storage stability. The optimum temperature for native and PU-immobilized … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,478 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNitrifying, Denitrifying and Heterotrophic Biomass Present in Moving Bed-ReactorAndreliza Carolina Del Grossi Oliveira, Camila Zoe Correa, Kátia Valéria Marques Cardoso Prates, Deize Dias LopesThis study was carried out to evaluate the main bacterial communities related to the removal of nitrogen in a moving bed-reactor treating landfill leachate, relating the physico-chemical parameters with the existence of these organisms in the mixed liquor (non-attached microorganisms) and Support Material (SM). The system was operated in two phases: Phase I (without effluent recirculation) and II (with recirculation, … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 25 Jan 2017 · 7,628 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of the Interaction between the Lining of a TBM Tunnel and the Ground Using the Convergence-Confinement MethodPierpaolo OresteThe support used when a tunnel is excavated by a shielded TBM is complex because it consists of two different materials: A concrete segmental lining and a filler annulus between the lining and the tunnel wall. A detailed analysis of the behavior of such a support system requires a three-dimensional numerical modeling and should also consider the presence of the … …American Journal of Applied Sciences, Vol. 12, Issue 4 · 17 Jun 2015 · 7,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractDefect Classification of Reinforced Concrete Structures with Nondestructive Tests Using Statistical and Machine Learning MethodsSajjad Sayyar-Roudsari, Armaghan Shalbaftabar, Farshid Damirchilo et al.In this study, twelve reinforced concrete beams were constructed, each with specified dimensions and initial compressive strength. The beams were divided into four groups: A control group without any defect, a void group featuring a centrally located void, a corrosion group and a debonding group. The impact echo test was used for nondestructive testing, gathering data on compressive and shear … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 11 Jun 2024 · 5,258 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerceived Anomic Threat, Beliefs in LGBTQ Conspiracy Theories and Support for Violence Against LGBTQ Minorities in a Highly Heteronormative Context: The Case of CameroonAchille Vicky Dzuetso Mouafo, Hermann Kevin Ekango Nzekaih, Gustave Adolphe MessangaThe literature on conspiracy theories reports that they are generated by a feeling of threat and are catalysts for the extremist and violent behavior of which many minority groups are victims, including members of the LGBTQ community. However, the fact that LGBTQ conspiracy theories are poorly documented in the scientific literature does not allow us to know what link they … …Current Research in Psychology, Vol. 10, Issue 1 · 21 Mar 2024 · 9,018 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Roofing Tiles Support Made from Bituminous PlywoodOuro–Djobo Samah, Sinko Banakinao, Komlan Lolo, Kodjo AttipouIn this study, a new design of roof support was investigated to improve the system of roof coverings with roofing tiles. Usually, wood frames or slabs are often used as support for roofing tiles, which presents many disadvantages such as the expensive cost of the slabs and sometimes inefficient Corresponding wood frames. The new design proposed in this study uses … …American Journal of Applied Sciences, Vol. 19, Issue 1 · 19 Sep 2022 · 6,370 accessesView PDFCite
Research ArticleOpen accessIn the abstractCrack Bridging and Deflection Toughening Mechanisms of Staggered Hydroxyapatite Lamellar Microstructure in BoneYuxi Liu, Xiaohui He, Shuge Li, Zhangdong SunThe observation experiment results of the microstructure of tibial cortical bone show that the cortical bone is a layered bio-ceramic composite material composed of Hydroxyapatite (HAP) and collagen arranged alternately. HAP is a reinforcing phase and accounts for a large proportion in cortical bone. These hydroxyapatites have long and thin sheet-like structures parallel to the outer surface of the bone, … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 31 Jul 2026 · 890 accessesView PDFCite
Research ArticleOpen accessIn the abstractCollection and Processing of Medicinal Raw Materials from Some Rare Plants in the Forest-Steppe Zone of Northern KazakhstanMarat Tynykulov, Svetlana Derbush, Marina Kuznetsova et al.Rare endemic plants of the forest-steppe zone of Northern Kazakhstan, including Adonis vernalis, Adonis wolgensis, Pulsatilla patens, and Pulsatilla multifida, represent valuable medicinal resources whose sustainable utilization requires optimized harvesting, processing, and conservation strategies. This study evaluated the effects of drying conditions, environmental factors, extraction techniques, and biotechnological approaches on the yield and quality of bioactive compounds from these species. … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 1 Apr 2026 · 1,595 accessesView PDFCite
