Research ArticleOpen accessEvery word in the titleInvestigation into the Use of Electrochemical Extraction to Draw Gold from Refractory OresBagdaulet Kenzhalyevich Kenzhaliyev, Zamzagul Duisenovna Dosymbaeva, Renata Ramilevna Iskhakova, Essen Nurgalievich SuleimenovThis paper studies the possibility of extracting gold by electrochemical leaching through the use of a sodium thiosulfate solution. In this regard, the requirements for environmentally sound technologies play a huge and vital role. Low extraction ratios and metal losses increase the cost of this process significantly and therefore it is necessary to reduce or prevent these disadvantages. Dissolution of … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 17 Nov 2015 · 6,684 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleResonance in Satellite's Motion Under Air DragRashmi Bhardwaj, Mani SethiThis article studies the attitude motion of a satellite in a circular orbit under the influence of central body of mass M and its moon of mass m, whose orbit is assumed to be circular and coplanar with the orbit of the satellite. The body is assumed to be tri-axial body with principal moments of inertia A < B < … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 7,003 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSoluble Tumor Necrosis Factor Receptor Type I and Dranulysin as Immunological Markers in Congestive Heart FailureSimone de Lima e Silva Deo, Maria Do Carmo Valente De Crasto, Alda Maria Da-Cruz et al.Previous studies have shown that circulating levels of cytokines are increased in patients with congestive heart failure (CHF), resulting in myocardial depression. In this work, we have determined serum levels of TNF-α and IFN-γ by ELISA, detected sTNFR-I by dot ELISA, as well as TNFα, IL-6, IL-10 and granulysin mRNA in unstimulated peripheral blood mononuclear cells (PBMC) by RT-PCR in … …American Journal of Immunology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,776 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThree Dimensional Multidirectional Geographical IP Traceback: Direction Ratio Sampling AlgorithmA. Rajiv Kannan, K. Duraiswamy, K. SangeethaProblem statement: An important and challenging problem is that of tracing DOS/DDOS attack source. IP traceback is the process of identifying the actual source(s) of attack packets, So that the attackers can be held accountable as also in mitigating them, either by isolating the attack sources or by filtering packets for away from the victim. Several IP traceback schemes have … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,238 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDEACT: Hardware Solution to Rowhammer AttacksTesfamichael Gebregziabher Gebrehiwot, Fitsum Assamnew Andargie, Mohammed IsmailDynamic Random Access Memory (DRAM) is a crucial component in modern computing devices. Improvements in process technology have significantly increased the speed and storage capacity of memory devices. However, as memory cells become smaller and closer to one another, annoying circuit disturbance errors such as the Row-hammer problem have become significant. Studies show that attackers can systematically exploit such errors … …Journal of Computer Science, Vol. 19, Issue 7 · 22 Jun 2023 · 6,489 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAgricultural Mechanization in Niger: What Role do Animals Play?Warouma Arifa, Chaibou Mahamadou, Saley Adamou LaoualiThe intensification of agriculture through the use of animal energy has been used since colonial times. This study aims to analyze the level of mechanization in Niger while relying on the role played by animals used for farming in the regions of Maradi and Zinder (Niger Republic). Data collection was carried out between June and August 2020, using a questionnaire … …American Journal of Applied Sciences, Vol. 19, Issue 1 · 7 Feb 2022 · 6,952 accessesView PDFCite
InvestigationOpen accessIn the keywordsChanges in the Composition and Properties of Meadow Solonchaks of the Ili Alatau Foothill Plain in the Republic of Kazakhstan during a Long Postmeliorative PeriodZhainagul Yertayeva, Saginbay Kaldybaev, Aigul Kaiyrbekovna BeketovaThe optimal depth of the groundwater table and the water-salt regime is of importance in the postmeliorative period. The scope of these studies is to provide scientifically grounded assessment of previously reclaimed soils (water irrigation with a total norm of 5000 m3/ha under conditions of deep horizontal drainage, 1986-1989) in the postmeliorative period of 2015-2016 and to develop parameters for … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 14 Oct 2017 · 7,268 accessesView PDFCite
Research ArticleOpen accessIn the keywordsContamination Risk Evaluation of Groundwater in the Canton of Portoviejo-Ecuador, using Susceptibility Index and two Intrinsic Vulnerability ModelsSuhail SharadqahThe present study aims to investigate the applicability of DRASTIC, GOD and SI models in evaluating the groundwater vulnerability and risk of contamination in the Canton of Portoviejo, Ecuador. The groundwater vulnerability to contamination has been evaluated using DRASTIC and GOD models. Both models were able to classify the study area into different sectors of variable vulnerability. The coincidence of … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 11 Feb 2017 · 7,516 accessesView PDFCite
