Research ArticleOpen accessIn the keywordsUncertainty Impact of the Effective Diffusion Coefficient on the Concrete Chemical DegradationA. BadaouiReinforced concrete is the construction material widely used in civil engineering. However, knowledge of its long-term performance and the uncertain impact of the environment on his behaviour make it difficult to accurate assessment of the durability of structures with time. When a structure is put into service, it is likely to damage, which origin can be physical, mechanical or chemical. … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 23 Jul 2015 · 7,758 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring the Relationship Between Skin Barrier Function, Sensitivity, and Repair MechanismsXiaoqing Yan, Yusong Shi, Jiguang YangFor healthy skin, the skin's barrier function must remain maintained. Many different molecular while immunological signaling mechanisms are involved in skin barrier control. The control of a healthy skin barrier, particularly acid mantle maintenance and proper amounts of ceramides, may help dermatologists develop remedies for skin barrier disruption disorders. In contrast, new medicines could focus on signaling pathways to offer … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 15 Feb 2026 · 1,893 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of the Effects of the Addition of Salt, Type of Additive and the Shelf Life, on Chemical Composition of Pennisetum purpureum (Schumach) (Maralfalfa) Silages in NigerMaman Lawal Abdoul Aziz, Seydou Korombé Hamza, Djibo Ibrahim et al.Seasonal variations in the quantity and quality of fodder constitute an obstacle to the development of ruminant breeding in Niger. This is why this study was carried out to evaluate the effects of salt addition, shelf life, and type of additive on the chemical composition of Pennisetum purpureum Schumach (Maralfalfa) silages. These aspects were retained because salt, in addition to … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 12 Sep 2024 · 4,720 accessesView PDFCite

Research ArticleOpen accessIn the abstractOptimization of Ultrasonic-Assisted Total Flavonoids Extraction from Flower of Albizia Julibrissin Durazz. by Response Surface Methodology for Characterization of Chemical Profile and Evaluation of Antioxidant and Tyrosinase Inhibitory ActivitiesYijie Cheng, Yuwen Zhang, Hanzhang Sun et al.To investigate the flavonoids in flower of Albizia julibrissin (‘He Huan Hua’ in Chinese), the ultrasonic-assisted extraction of total flavonoids from ‘He Huan Hua’ was optimized by response surface methodology and the chemical profile was characterized by HPLC- QTOF-MS/MS. What’s more, the antioxidant and tyrosinase inhibitory activities of ‘He Huan Hua’ were also evaluated in this study. The extraction time, … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 14 Mar 2022 · 6,733 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Climate Factors on the Epidemiology and Management of Potato virus YMahabuba Mostafa, Md. Motaher HossainPlant viruses give rise to potential loss to global crop production and have the potential to cause widespread damage. Potato virus Y (PVY) is a plant virus that belongs to the genus Potyvirus and the family Potyviridae and it is considered a major concern, particularly for solanaceous crops such as potatoes. PVY represents the largest cluster of plant viruses, encompassing … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 31 Aug 2024 · 4,758 accessesView PDFCite
Research ArticleOpen accessIn the abstractCurrent Growth Conditions of Populus Diversifolia Schrenk and Populus Pruinosa Schrenk in the Syr-Darya ValleyPolina Vesselova, Karina Makhmudova et al.In the context of urbanization of territories and the intensification of agriculture, the biological diversity of animals and plants in their habitats is degrading. The purpose of the study is to determine the edaphic factors affecting the growth of Populus diversifolia Schrenk and Populus pruinosa Schrenk, as well as anthropogenic factors affecting their conservation in the Syr-Darya valley (Kazakhstan).

Review ArticleOpen accessIn the abstractChemical Coagulation/Flocculation Processes for Removal of Phenolic Compounds from Olive Mill Wastewater: A Comprehensive ReviewMounia Achak, Fatima Elayadi, Wafaa BoumyaOlive oil extraction processes generate three phases: Olive oil, solid residue (pomace) and aqueous liquor Olive Mill Wastewater (OMW). OMW causes serious environmental deteriorations such as coloring of natural waters, alteration of soil quality, phytotoxicity and odor nuisance. The direct discharge of this effluent into the soil bring various negative effects on the environment, due to its high load of … …American Journal of Applied Sciences, Vol. 16, Issue 3 · 30 Mar 2019 · 10,494 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation of Thermo-Physical Properties of Soil Using Solarisation TechnologyAhmed Abed Gatea Al-Shammary, Abbas Kouzani, Akif Kaynak et al.Soil Thermo-Physical Properties (TPP) depend on heat transfer in the soil. This paper presents a study on different soil solarisation technologies influenced by soil TPP. This study evaluates three factors: The tillage depth for soil at three levels (15, 25 and 45 cm), the number of plastic film at three levels (single, double and without plastic film) and three cases … …American Journal of Applied Sciences, Vol. 14, Issue 7 · 17 Jul 2017 · 7,957 accessesView PDFCite
