Research ArticleOpen accessIn the abstractEffects 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 · 5,306 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Transboundary Movement of Hazardous Waste: A Contribution to Improve the Present Technical-Judicial ModelGiancarlo Carosso, Cesare Luceri, Pierpaolo OresteThe expression &#34the transboundary movement of hazardous waste&#34 refers, from the technical point of view, to a series of phases that begin with the creation of a hazardous waste and includes its identification according to international, regional and national standards, its delivery to specialized companies and its movement from the exporting country to the importing country; these phases end with … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 13 Jul 2012 · 7,156 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeometric-Cinematic Synthesis of Planetary MechanismsNicolae Petrescu, Florian Ion Tiberiu PetrescuThe simple planetary mechanism is geometrically synthesized by determining the four tooth numbers of the component wheels. There are four main conditions that if not obeyed the mechanism will be blocked, will work with interruptions, or will not work at all. (a) The first condition in the geometric-kinematic synthesis of a simple planetary is the uniform loading of satellites (satellite … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 28 Aug 2018 · 7,463 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrevalence of Endo and Ectoparasitism of Sheep in Northern KazakhstanDinara Seitkamzina, Botakoz Akmambaeva, Gulmira Abulgazimova et al.Invasive diseases of sheep are widespread worldwide, including in Kazakhstan. Recently, in the Akmola farms of Kazakhstan, there has been an increase in the spread of gastrointestinal diseases in sheep. The study aimed to assess the Prevalence (P) of sheep parasitosis in Northern Kazakhstan to develop effective prevention and control measures. Five-hundred and sixty-four sheep were studied in four rural … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 3 · 23 Sep 2023 · 5,660 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Analysis of Postmodern Design for Information Technology in Education in Relation to ModernismSaeid Zarghami Hamrah, Parvin BazghandiProblem statement: The purpose of present study is a comparative analysis of the philosophical bases of postmodernism in relation to modernism and suggesting the necessities of each base in the designing information technology in education. Approach: The research method for the present study was comparative analysis. Results: The first base was rejection of objective view toward the universe and accepting … …Journal of Social Sciences, Vol. 8, Issue 3 · 26 Mar 2012 · 8,070 accessesView PDFCite
Research ArticleOpen accessIn the abstractSilicone Modeling of the Interior Spaces of Hollow Organs: Use in Dog and Manatee Respiratory Tract and in a Beef HeartCharles J. Grossman, Richard Hamilton, Lisa A. Close-Jacob et al.Problem statement: The mechanism, by which the Florida manatee (Trichechus manatus latirostris) vocalizes, remains unknown because the manatee larynx does not contain true vocal cords. Since sound can be generated when air passes through a narrow respiratory structure we needed to visualize the internal anatomy of manatee respiratory tract to locate any candidate regions for study. Approach: To visualize the … …OnLine Journal of Biological Sciences, Vol. 11, Issue 1 · 6 Jul 2011 · 7,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Spatial-Temporal Variability of Nitrates in a Section of the Cuneo Plain (North West Italy)Massimo Vincenzo Civita, Adriano Fiorucci, Bartolomeo VignaThe study of an aquifer system is very important, but also very complicated because of the high temporal and spatial variabilities of a system and because of the phenomena that are at play within the system. It is from these problems that the necessity arises of finding methods that are able to extend point knowledge to an entire area, while … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,733 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Crude Polyphenol Oxidase Activity in Buckwheat SproutsYuedong Song, Yangfang Zhang, Yilin Wang et al.Buckwheat sprouts can not only effectively reduce the trypsin inhibitor in buckwheat grain, but also improve the content of bioactive ingredients such as flavonoids and other effective components. However, Polyphenol Oxidase (PPO) in buckwheat sprouts causes browning of food, which limits the application of buckwheat sprouts in food. In addressing this problem, studying the characteristics of PPO in buckwheat sprouts … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 25 Jun 2021 · 6,487 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Binary and Ternary Models in Powder Packing Density for Additive Manufacturing ApplicationsTaher M. Abu-Lebdeh, Oluwatobiloba Adetokunbo KalejaiyePowder packing is a very important aspect of additive manufacturing (3-D printing), as it directly impacts the final physical and mechanical properties of the printed objects. Improving the packing density of powder directly impacts the microstructure of the finished 3D-printed product, which also contributes to the surface finish. In order to achieve the densest packing for a powder, different sizes … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 15 Jun 2021 · 7,284 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploratory Study on the Fracture Resistance of Cast GlassTelesilla Bristogianni, Faidra Oikonomopoulou, Fred Veer, Rob NijsseThe emerging interest in the architectural applications of cast glass components reveals a knowledge gap on the mechanical properties of cast glass. Apart from its chemical composition, cast glass is characterized by its manufacturing history and thermal profile, often inheriting a set of defects that define its properties. The role that inhomogeneities in the bulk of voluminous glass components have … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 4 Jun 2021 · 7,361 accessesView PDFCite
