Research ArticleOpen accessIn the abstractOne can Achieve the Nuclear Fission Reaction of Lithium by Accelerated Hydrogen Nuclei or NeutronsRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuThe idea circulated among physicists that in the upper area of the physical elements the fission reaction can be obtained and in the lower one the fusion reaction occurs. In the presented paper we want to impose another rule, namely the obtaining in the lower part of the physical elements of the fission and fusion nuclear reactions, with the obvious … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 3 · 7 Sep 2021 · 9,516 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiochemical Indicators and Nutritional Value of Horsemeat Infected by Parascaridosis and Sampled from the Surrounding Areas of Semipalatinsk Nuclear Test Site, KazakhstanShyngys Suleimenov, Sergazy Duyssembaev, Ainur Serikova et al.Due to high prevalence of the Parascaris equorum among horses, the effect of Paracardiosis infestation on nutritional and biological values of meat is required. In an effort to analyze the radionuclides contents, biochemical parameters and biological value of horsemeat collected from different areas of Semipalatinsk Nuclear Test Site (SNTS) of Kazakhstan. The prevalence of parascaridosis was performed following standard protocols. … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 9 Feb 2021 · 6,600 accessesView PDF Cite

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 PDF Cite

Research ArticleOpen accessIn the abstractA Cross-Sectional Study of the Prevalence of Hepatitis C Virus InfectionOmar Atrooz, Rehab Thunibat, Ihssan AtroozLiver pain is increased by hepatotropic viruses, such as the Hepatitis C Virus (HCV). This illness can progress to cirrhosis and hepatocellular cancer. This study aims to determine the prevalence of hepatitis C in the Southern Jordanian cities (Karak and Tafilah) as well as the correlations between alanine Aminotransferase (ALT), Aspartate aminotransferase (AST), age and gender in hepatitis C patients. … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 5 Jul 2024 · 4,414 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Impact of Changes in Forage Vegetation for Saiga (Saiga Tatarica) On Natural Pastures in The Steppe Zone of the West Kazakhstan RegionAmanay Myrzabayev, Zhanbolat Ibraibekov, Zhangeldi Ussenov et al.This study investigates the impact of recent climate changes and reduced anthropogenic pressure on the vegetation cover in the steppe regions of Russia and Kazakhstan, particularly focusing on the effects on saiga (Saiga tatarica) populations. By the late 1990s, a significant shift towards the dominance of grasses and the reduction of herbaceous plants in semi-arid and arid regions was observed, … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 7 Feb 2026 · 1,765 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModern Propulsions for the Aerospace IndustryRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuThis paper aims to contribute to the study of propulsion systems for modern aerospace vehicles with the obvious aim of improving them and to give them the ability to move much faster and easier in any direction, for a very long time, going through huge distances without the need of fuel refueling, as is the case with conventional, chemical propulsion. … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 12 May 2018 · 7,995 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThermal Stability Analysis in a Two-Step Reactive Cylindrical StockpileR.S. Lebelo, R.K. Mahlobo, K.C. MoloiThermal stability analysis in a cylindrical stockpile of reactive material undergoing a two-step low-temperature oxidation reaction is studied in this article. The reactant consumption in this case is neglected and heat transfer with thermal stability are investigated by application of the energy equation. The complicated combustion process results with nonlinear interactions and hence the nonlinear partial differential equation governing the … …American Journal of Applied Sciences, Vol. 15, Issue 2 · 6 Dec 2017 · 7,654 accessesView PDF Cite

This research was conducted from July until December 2018 in the rice fields of Girimarto District, Wonogiri Regency with a survey method and land sampling by purposive sampling (intentionally) at a depth of 0-20 cm … …American Journal of Agricultural and Biological Sciences, Vol. 15, Issue 1 · 25 Jun 2020 · 7,936 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOne Can Slow Down the Aging through AntioxidantsRaffaella Aversa, Relly Victoria V. Petrescu, Antonio Apicella, Florian Ion T. PetrescuFree radicals are natural nanoparticles which are doing their part well defined in the human cell, but then they must be annihilated or eliminated to not destroy the cell or another part of our body. It has been shown that residual free radicals in the body are responsible for the aging. The role to annihilate them is ful-filled by the … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 8 Dec 2016 · 10,070 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUncertainty 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 PDF Cite
