Research ArticleOpen accessEvery word in the titlePetrography and Geochemistry of Orin-Ekiti Basement Rocks, Southwestern Nigeria: Implications on BauxitizationAbel Ojo Talabi, Akin Ojo Oyinloye, Olusola Amos Olaolorun et al.The petrography and geochemistry of Orin-Ekiti Basement rocks were evaluated to determine their mineralogical and chemical composition, assessed their petrogenesis and susceptibility to the formation of bauxitic clay. Ten representative rock samples were selected for thin section petrography and bulk rock geochemical analysis using Petrographic microscope and XRF, Rh Tube, 3k Watt respectively. Field observations revealed charnockites as the dominant … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 1 Jan 2018 · 8,767 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRocks with Asbestos: Risk Evaluation by Means of an Abrasion TestBellopede Rossana, Clerici Carlo, Marini Paola, Zanetti GiovannaNaturally occurring asbestos and asbestiform minerals can be found in metamorphic rocks and in the soil of the alluvial plains. Problem statement: The definition of the "free-asbestos rock" and the limit to consider a rock or a soil safe is still a controversial issue. American and European laws did not present any method to define the hazard of the green … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Oct 2009 · 7,667 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOccupational Safety and Health in Tunnelling in Rocks Formations Potentially Containing Asbestos: Good Practices for Risk Assessment and ManagementDavide Labagnara, Mario Patrucco, Achille SorliniIn tunnelling operations, Occupational Safety and Health (OS&H) and Environmental Protection of the areas close to the tunnel portal become even more critical in case of rock formations potentially containing asbestos, quartz, radioactive elements, etc. In order to limit the workers’ exposure and the environmental impact becomes in these cases of paramount importance to preliminarily analyze and quantify the possible … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 26 May 2016 · 7,646 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEnvironmental and Safety Accidents Related to Blasting OperationLazar Kricak, Vladislav Kecojevic, Ivan Jankovic et al.The blasting process remains a potential source of numerous environmental and safety accidents. The majority of these accidents were contributed to the flyrock and lack of blast area security. A field-scale investigation related to flyrock accident was conducted in an andesite quarry where rocks up to 50 cm in diameter were propelled almost 300 m from the center of blasting … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 18 Jun 2012 · 8,896 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPetrography and Sulphur Isotope Studies of Pyrites in the Muteh Gold DepositM. J. Abdollahi, M. H. Karimpour, A. KheradmandProblem statement: The Muteh mining district is located in 70 km northeast of Golpaygan city within the Sanandaj-Sirjan metamorphic belt. There are 2 gold mines, 7 gold occurrences and numerous mineral indices in the Muteh gold district. There are few researches on Muteh gold district, but a detailed model is not clear yet. The aim of this study is to … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,131 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Spectrophotometric Method for Determination of Iron in Herbs, Spices and Beans with 2,6-Diacetylprydine Dioxime and 2-Acetylpyridine MonoximeZ. R. Komy, E. A. Abu-Gharib, A. DesokyThe reaction of iron (II) with 2, 6-diacetylprydine dioxime (H2dapd) and 2-acetylprydine monoxime (Hapm) in 10% and 60% v/v ethanol-water solution at pH 2.5 and 7.5, respectively, were studied using direct and first derivative spectrophotometry. Fe (III) is reduced by H2dapd and gives iron (II) complex. A simple, rapid, selective and sensitive method for the determination of Fe (II), Fe … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,960 accessesView PDFCite
Research ArticleOpen accessIn the abstractLess Biased Approach for Sandstone Pore SegmentationDaffa Abiyyu Murtadha Kurnia, Iman Herwidiana KartowisastroReservoir characterization is a fundamental process in estimating reserves within petroleum and hydrogeological systems, where the precise determination of pore space dictates the validity of fluid flow models. Although X-Ray Computerized Tomography (XRCT) has become the standard non-destructive evaluation method for visualizing the internal structure of rocks, the data interpretation process still faces challenges during the image segmentation stage. Conventional … …Journal of Computer Science, Vol. 22, Issue 6 · 15 Jun 2026 · 1,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractLandslide Susceptibility Mapping with GIS in Nagi Dada Area of Panauti Municipality, Kavrepalanchwok District: A Comparison Between AHP and FR MethodArju Bhattarai, HimLal Shrestha, Asim Timalsina et al.Landslide Susceptibility Maps (LSM) are useful for both development planning and disaster management. Currently, LSMs are primarily created using GIS and remote sensing techniques. Landslide susceptibility mapping relies heavily on selecting and weighting causative elements based on their impact on slope instability. GIS is useful for calculating static parameters such as slope and aspect, as well as generating landslide susceptibility … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 4 · 22 Aug 2024 · 7,093 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtended Fuzzy Decision Support Model for Cropland Recommendation of Food Cropping in IndonesiaLucky Christopher Chen, Nurcahyo Wibowo, Ditdit Nugeraha UtamaFood crops are the preferred crops to be cultivated on agricultural land in Indonesia, which has a wide area available for use as agricultural land. Each region’s agricultural lands in Indonesia have distinct features (e.g., water capacity, land porosity, land height, etc.). Rice, maize, red beans and green beans are significant food crops that are commonly cultivated in Indonesia. The … …Journal of Computer Science, Vol. 17, Issue 8 · 8 Sep 2021 · 6,501 accessesView PDFCite
