Research ArticleOpen accessEvery word in the titleComparison of Two Analytical Techniques For Lead Determination in Soils and Mosses SamplesAlbert Maxhuni, Pranvera Lazo, Musaj PaqariziThe aim of this study was to compare the results of the lead levels obtained by two different techniques in the soil and mosses samples taken from the entire territory of the Republic of Kosovo. The atmospheric deposition of lead through the biomonitoring technique was done for the first time in Kosovo by using quartz tube flame Atomic Absorption Spectroscopy … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 22 Jun 2012 · 6,897 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComparative Studies of the Determination of Divalent Cadmium, Lead and Copper in the Boiling Medicinal Herbs by Stripping Voltammetry and by Atomic Absorption SpectrometryAhmed Hassan, Jamal A. MayoufCadmium, lead and copper were determined in ten Libyian boiling medicinal herbs samples by differential pulse anodic stripping voltammetry as well as by atomic absorption spectrometry. Voltammetric method was done at Hanging Mercury Dropping Electrode (HMDE) in Briton-Robinson buffer solution of pH ~2.1 at 25± 0.1°C. The sample preparation was carried out by boiling 2.0g of a finely pulverized plant … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,029 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcaricidal Activity of Azadirachta indica (Neem Tree) and Carica papaya (Papaya) Leaf Extracts against Rhipicephalus sanguineus (Dog Ticks) Using Spray MethodAlfredo Vita Corpuz, Carmela Montoya Florentino, Paul Erman Tabuloc Quilana et al.Ticks pose a serious threat to dogs, with synthetic acaricides leading to environmental impact and resistance concerns. While Azadirachta indica and Carica papaya have shown acaricidal potential against Rhipicephalus sanguineus, their efficacy against dog ticks has not been thoroughly investigated. This study determined the acaricidal activity of A. indica and C. papaya leaf extract against R. sanguineus, both individually and … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 22 Apr 2025 · 8,409 accessesView PDFCite

Research ArticleOpen accessIn the abstractInputs of Numerical Simulation into the Development of Shock Adhesion Tests on Advanced MaterialsMichel ArrigoniAdvanced materials- such as assemblies, composites and materials obtained by additive methods - have met a great success in the industry of advanced technologies. They allow combining a variety of different materials and following sophisticated geometries. However, their mechanical behavior, bulk as well as in assembly, remains to be better understood to assess their reliability. For this reason, laser induced … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 10 Jan 2020 · 6,871 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification of Venom-Specific Fingerprints of Clinically Relevant Uruguayan Snakes by MALDI-TOFNorma Suarez, Victor MoraisSnakebite envenomation is a particular public health problem in many areas of the world, including extensive areas of Latin America. In particular, in Uruguay, snakebite accidents are caused by two snakes of the genus Bothrops: Bothrops alternatus and Bothrops pubescens. The only effective treatment available is the administration of the specific antivenom. Although there is an ELISA that allows the … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 3 · 26 Jul 2019 · 8,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractCross-Section Optimization of Sandwich-Type Cylindrical Wind Turbine TowersStylianos M. Vernardos, Charis J. GantesAs wind energy is aggressively expanding within the alternative sources' part of modern world's energy pie, the need of addressing various obstacles that limit further wind utilization becomes all the more urgent. From a structural engineering point of view, surmounting the tower-base diameter limitation, dictated by the current transportation capabilities, is one of the industry's primary issues. The concept presented … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 7 Aug 2015 · 7,993 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Algorithm for Variable and Samples Selection in Multivariate Calibration ProblemsKelton de Souza Santiago, Anderson Silva Soares, Telma Woerle de Lima et al.One of the main problems of quantitative analytical chemistry is to estimate the concentration of one or more species from the values of certain physicochemical properties of the system of interest. For this it is necessary to construct a calibration model, i.e., to determine the relationship between measured properties and concentrations. The multivariate calibration is one of the most successful … …Journal of Computer Science, Vol. 11, Issue 4 · 8 Jun 2015 · 7,381 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE ASSOCIATION OF IONS IN THE SOIL SOLUTION OF SALINE SOILSA. P. Endovitsky, T. M. Minkina, V. P. Kalinichenko et al.The chemical equilibrium in the soil solution determines the dynamics of its material composition, migration and accumulation of salts.
