Research ArticleOpen accessAll words, across the recordPossibilities of Stabilizing Soil Biological Activity by Treating Seeds With a Biological Preparation Based on Phosphate Mobilizing Bacteria in the Conditions of the Aral Sea Region of KazakhstanZhanar Zhumadilova, Laura Tokhetova, Shorabayev Yerik et al.This study examined the effect of Phosphate-Mobilizing Bacteria (PMB) as a pre-sowing treatment for forage crop seeds. The objective was to assess the potential of these bacterial biopreparations to improve both crop productivity and soil fertility. Research methods included agrochemical, microbiological, and conventional field analyses. The findings revealed that pre-sowing seed treatment with PMB increased crop yields by 7.4% to … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 24 Sep 2026 · 642 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMixed Formulation for a Signorini ProblemTedjani Hadj Ammar, Benabderrahmane BenyattouProblem statement: This study deals with the study of a Signorini Problem (SP) of unilateral contact between two a linear or non linear elastic bodies. Approach: We present two variational formulations noted P1, P2, of the considered problem, where P1 depends on the displacement field and P2 depends on the stress field. In the linear case, under assumptions, then the … …Journal of Mathematics and Statistics, Vol. 8, Issue 2 · 23 Apr 2012 · 7,224 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordEffects of Electromagnetic Field Frequency on the Behavior and Mortalities of Living OrganismsTatyana Degtyarevskaya, Andrei VokhmintsevThe objective of this investigation is to assess the influence of electromagnetic fields on living organisms. The impact of electromagnetic radiation of varying intensities on alterations in behavioral responses and mortality rates of living organisms was examined under controlled laboratory conditions at the first Moscow state medical university, named after I.M. Sechenov. The subjects of the study encompassed 10 specimens … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 19 Jan 2024 · 5,296 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordScreening of Dominant Cellulose-Degrading Microbe in Humus and Optimisation of its Enzyme Producing Conditions and Application Optimization of Enzyme Production Conditions and Evaluation of Efficient Straw Degradation by Penicillium oxalicumGailing Wang, Chendi Li, Yanan Guo et al.The slow degradation of returned straw adversely affects seedling survival rate. To shorten the degradation time of lignin in maize straw in warm temperate regions, a cellulolytic microbial strain that can secrete polymer with high enzymatic activity was isolated from the humus, which helped to identify an effective strain to expedite the decomposition of returned maize straw. Using the molecular … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 2 · 23 May 2023 · 5,300 accessesView PDFCite
