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 · 6,729 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Nitrogen Non-Point Sources in Po River Near TurinGiuseppe Genon, Franco MarcheseThe non-point hydraulic and nitrogen loads in the stretch of Po river upstream and downstream from the city of Turin have been investigated, on the basis of regular data concerning quality and flow rates in the river in different periods of a reference year. The collected data have been organized in terms of hydraulic and mass balances, taking into account … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,642 accessesView PDFCite
Research ArticleOpen accessIn the abstractComprehensive Assessment of Spatial Distribution of Road-Network Vulnerability in South AsiaPan Yuqi, Jiang Penghui, Li Manchun, Chen DengshuaiUnexpected phenomena-natural disasters, accidents and wars-can disrupt regional traffic systems because of the incapacities of road networks to sustain inflicted impacts. Therefore, the assessment of road-network vulnerability becomes integral to traffic-safety-maintenance and accident-prevention procedures. This study demonstrates the development of a comprehensive network system based on suggested improvements in node extraction, road construction and network attribution. An indicator system for … …American Journal of Environmental Sciences, Vol. 17, Issue 6 · 24 Dec 2021 · 6,446 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Performance of Supervised Learning Algorithms for Flood Prediction in Kemaman, TerengganuNur Najihah Shaaban, Norlida Hassan, Aida Mustapha, Salama A. MostafaFlood is one of the most destructive phenomena all over the world. Because the flooding uncertainties and the urgency to prepare for disaster management, three specific technique approaches are compared in this study to predict the flood occurrence based on historical rainfall data. The study involved the rainfall data in Kemaman, Terengganu between 2017 and 2018 extracted from the official … …Journal of Computer Science, Vol. 17, Issue 5 · 7 May 2021 · 6,887 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn 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 · 7,005 accessesView PDFCite
Literature ReviewOpen accessIn the abstractBook Review: Quantum Field TheoryChristina PospisilThe textbook presents a summary about Quantum Field Theory (QFT) with mathematical details. A wide range of main concepts and additional topics in quantum field theory is displayed in the academic textbook to scientists. Field theory describes and represents phenomena physically and mathematically through forces acting and spreading as field in space. Quantum field theory is constructed and introduced from … …Physics International, Vol. 12, Issue 1 · 22 Feb 2021 · 8,544 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Reliable Method of Analysis for Geotechnical DataAbdolrasoul Ranjbaran, Mohammad Ranjbaran, Fatema RanjbaranGeotechnical engineering is the art of making decisions in the presence of uncertainty, where real world problems are treated and this is associated with uncertainties arising from various sources. The sources of uncertainty may be divided into uncertainties of nature and uncertainties of mind. The uncertainties of nature are due to variation of encountered phenomena, e.g., the shear strength in … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 26 Dec 2020 · 7,573 accessesView PDFCite
