Research ArticleOpen accessEvery word in the titleInvestigation of Factors Influencing the Reproduction of Non-Gregarious Locust Pests in Northern Kazakhstan to Substantiate the Forecast of their Number and Planning of Protective MeasuresKurmet Baibussenov, Aigul Bekbaeva, Valery Azhbenov et al.The article presents the results of many years of research on the phytosanitary state of agricultural land for non-gregarious locust pests. As polyphagous pests, non-gregarious locusts are one of the key destabilizing factors in the production of economically important agricultural plants in the agricultural regions of Northern Kazakhstan. Research on the long-term population dynamics of non-gregarious locust pests to determine … …OnLine Journal of Biological Sciences, Vol. 21, Issue 1 · 17 Mar 2021 · 6,724 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Investigation of Work-Related Fatigue Levels and Related Factors among Emergency Nurses: A Primary Quantitative StudyKhaldoun Ismail, Mahmoud Al-Masaeed, Rawan Alsababha et al.One of the most frequent phenomena among shift workers, particularly nurses, is work-related fatigue. There is a necessary demand for research in the area concerning the relationship between socio-demographic factors, occupational variables and work-related fatigue among Arabic, including Jordanian nurses, given the lack of knowledge. This study targets evaluating the magnitude of the relationship between socio-demographic and occupational factors and … …International Journal of Research in Nursing, Vol. 12, Issue 1 · 5 Mar 2021 · 7,009 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReinforcing Effect of Strain Gauges on 3D Printed Polymers: An Experimental InvestigationSalvatore Brischetto, Roberto TorreStrain gauges are ordinary transducers for strain measuring; their operation relies on the electrical resistance, which varies as the underlying substrate is subjected to mechanical deformation. The mechanical strain can be obtained by converting the electrical signal through a gauge factor, provided by the manufacturer. It was demonstrated that its values are not unique; it may be influenced by the … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 9 Jan 2021 · 7,662 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigation of Climatological Components on Runoff Modeling using SWATHamid-Reza Rabiefar, Sayed-Reza Alvankar, Kaveh Ostad-Ali-AskariIt was planned most hydraulic projects, for instance barriers, it was defined the overflow of the rivers. If the river absences any position to measure the yield, the hydraulic models can be utilized to estimate it. SWAT is widely-used computerized mockups. It was required to feed such influential climatological information as precipitation, temperature, wind speed, solar radiation and relative humidity, … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 30 Dec 2020 · 6,118 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleExperimental Investigation on the Failure Mechanism of Bovine Bone by Three-point Bending TestsHua Li, Rujie Gao, Ruiqi Li et al.Bone damage is a common type of sport injury. The loading rate affects the type of fracture and the degree of soft tissue injury. In view of the problem of whole bone bending damage and failure, this paper introduces the test method of bovine bone bending and the mechanism of bending failure under different loading rates is analyzed through experimental … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 10 Jul 2020 · 6,541 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvestigation of Sandwich Panel Under High Temperature Loading Using Finite Element AnalysisSajjad Sayyar Roudsari, Armaghan Shalbaftabar, Taher M. Abu-Lebdeh et al.Structural and nonstructural members are always encountered with extreme loading conditions. In case of nonstructural members, the failure happens much sooner due to lack of load capacity. The nonstructural elements are not designed for structural loading conditions. However, they might be impacted to other loading types such as fire. In recent years, the use of 3D panel is one of … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 1 Jul 2020 · 7,683 accessesView PDFCite
