Research ArticleOpen accessIn the abstractOptimization Design of Sea Cucumber Cleaning Parameters by Water JetXu Zhang, Changyuan Zhang, Fei Gao et al.Aiming at the problem that the cleaning effect and surface integrity of the mechanical cleaning process cannot be solved simultaneously in the pretreatment of sea cucumber and according to the requirements of high efficiency, high quality and economy of sea cucumber body surface cleaning, a continuous directional cleaning device for sea cucumber abdomen and back based on the principle of … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 15 Mar 2021 · 6,174 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Cement Kiln Dust on the Soil Electrical ResistivityHamid Ranjkesh Adarmanabadi, Arezou Rasti, Mehrdad RazaviElectrical resistivity is a non-destructive, cost-effective and sensitive method to evaluate soil's physical and chemical properties. Electrical resistivity has been used widely in surface and subsurface exploration. The electrical resistivity is directly related to the subsurface geotechnical and geothermal properties like porosity, temperature, salinity and water content. Recently uses of waste material as an additive to improve the soil engineering … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 14 Jan 2021 · 7,272 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcetylation Process and Antioxidant Activity of a Polysaccharide from Loquat (Eriobotrya japonica) LeavesYiting Xue, Xiao Ding, Ze Zhang et al.Chemical modifications of polysaccharides can provide an opportunity to obtain new agents with possible therapeutic uses. In this study, a water-soluble polysaccharide extracted from Loquat Leaves (coded LLPs) was purified by the column chromatography, which was used to investigate its acetylation process by the acetic anhydride method. The Degree of Substitution (DS) was used as the index, the effect of … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 1 Jan 2021 · 7,056 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing of Copper (II) Adsorption Efficiency by Mixing Plantain and Orange Peelings as Bio-Sorbent SupportSamomssa Inna, Ebelle Epoi Charlotte Alvine, Adjia Zangue Henriette, Sieliechi JosephThe present study focuses on the valorization of plantain and orange peels in the field of water treatment contaminated by heavy metals, especially copper (II). To carry out this study, simplex centroid mixture design was used to determine best mixture from plantain and orange peelings through iodine number, specific surface area and point of zero charge. The influence of contact … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 19 Oct 2020 · 6,920 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Different Cycles of Thermal Fatigue in Steel Metallurgical Aspects ASTM SA-516 Grade 60Eder Hermes Bicharra, Jorge Luis Braz Medeiros, Luciano Volcanoglo Biehl et al.The ASTM SA-516 steel has applications in compact steam boilers of low and medium temperature and pressure. Deterioration can show when exposed to high temperatures due to fuel gases burning. Failures detected by inspections done in a frequency required by standard on the boilers. Among the main failure mechanisms found in materials used in boilers, creep, corrosion, when subjected to … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 28 Aug 2020 · 6,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoil Organic Carbon Pool and its Storage in Arial Beel Wetland Soils of BangladeshMd. Faruque Hossain, ASM Maksud Kamal, Monera Akhter Eva et al.The actual quantity of Soil Organic Carbon (SOC) stored in wetlands can only be estimated within a broad range of uncertainty. An accurate assessment of the size and distribution of the SOC storages in wetland resources is very difficult to obtain, therefore, the proposed research objective is to measure SOC storage and its pool on wetland soils of Arial beel … …American Journal of Environmental Sciences, Vol. 16, Issue 3 · 17 Aug 2020 · 7,382 accessesView PDFCite

Research ArticleOpen accessIn the abstractDilution of Single Port Submerged Diffuser Clogged by a Free Rotating PropellerAhmed Ashmawy, Mahmoud Aboelnasr, Entesar Abdallh El-Ghorab et al.Thermal pollution raises the water source temperature and thus causes a change in the physical, chemical, and biochemical properties of water. That makes limitations for designing cooling systems, which increase its cost. Single port submerged diffuser is used for the disposal of hot water. It is a form of once-through cooling systems, and it is between the surface discharge and … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 6 May 2020 · 6,869 accessesView PDFCite
Research ArticleOpen accessIn the abstractSensing the Hydrogeomorphology and Palaeohydrologic Features of Mars Planet with Inference from the Egyptian Desert: An Insight from Satellite ImagesMohamed YousifThe water access in any planet of the universe can be considered a crucial evidence for life existence. The study of Mars has special importance where it has a complex preserved geological record of a time period longer than on Earth. Many regions of Mars planet are subjected to observations through the obtained satellite images in comparison to similar areas … …Space Science International, Vol. 4, Issue 1 · 27 Apr 2020 · 13,200 accessesView PDFCite
