Research ArticleOpen accessEvery word in the titleROLE OF SALINITY IN PRECIPITATION AND WELL WATER DEPTH RELATIONSHIPManoj K. JhaExcessive groundwater pumping can decrease the amount of fresh water flowing towards the coastal discharge areas, allowing salt water to be drawn into the fresh water zones of coastal aquifers. This process gets complicated with the frequent change behavior of groundwater levels in observation wells. The fluctuation happens due to various reasons but can be directly correlated with the precipitation … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 27 Mar 2014 · 7,952 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMeasurement of Fibrinogen Concentration in the Plasma of Dogs: A Comparison Between Heat Precipitation and Modified Thrombin Clotting Time MethodLabrini V. Athanasiou, Theodoros A. Petanides, Manolis K. Chatzis, Manolis N. SaridomichelakisFibrinogen is a glycoprotein that plays a key role in blood clotting and is also a non-specific indicator of inflammation. The most widely used techniques for measuring plasma fibrinogen concentration include heat precipitation (Millar’s technique) and modified thrombin clotting time (Clauss method). Both techniques have been automated in a haematology analyzer (QBC-Vet Autoreader®, IDEXX; Millar’s technique) and in a newly … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 2 · 18 May 2013 · 7,449 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTrends and Multifractal Analyses of Precipitation Data from Shandong Peninsula, ChinaMeng Gao, Xiyong HouProblem statement: Water shortage is a very serious problem in Shandong Peninsula, which is one of the most rapidly developed zone in China. As the major source of water supply is in this area, precipitation is crucial to sustainable development in Shandong Peninsula. The purpose of the present study is to investigate the trend and characteristics of precipitation during the … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 23 May 2012 · 7,160 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSynthesis of Baso4 Nanoparticles by Precipitation Method Using Polycarboxylate as a ModifierMohamed El-Shahate Ismaiel Saraya, Inas Mostafa BakrProblem statement: Barium Sulfate (BaSO4) is suitable for many applications because of its whiteness, inertness and high specific gravity. Approach: Nanoparticles of barium sulphate (BaSO4) have been synthesized from barium nitrate by precipitation method in the presence of water soluble organic polycarboxylic polymer as a modifying agent. Transmission electron microscopy, Scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray powder … …Current Research in Nanotechnology, Vol. 2, Issue 1 · 29 Jul 2011 · 15,705 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePart I: Removing of Zn(II) from Polluted Water: Determination of Precipitation Limit Of Zn(II) Ion With 2-Hydroxy-1,2,3-Propanetricarboxylic AcidFatmir Faiku, Haxhere Faiku, Arben Haziri et al.Problem statement: The goal of this research was to investigate the condition for removing of Zn cation from water, through precipitation method with 2-hydroxy-1,2,3-propanetricarboxylic acid as ligand. Approach: In this study we examined the precipitation of Zn(II) ion in water solutions of ZnSO4 × 7H2O (1×10-2 and 5×10-3 mol L-1) with 2-hydroxy-1,2,3-propanetricarboxylic acid (1×10-1-1×10-3 mol L-1) in constant ionic strength … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 6,969 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetermination of Precipitation Limit of Zn(II) Ion with (2S)-2-Aminobutanedioic AcidFatmir Faiku, Haxhere Faiku, Arben Haziri et al.Problem statement: In this study we examined the precipitation of Zn(II) ion in water solutions of ZnSO4.7H2O (1.10-2 and 5.10-3 mol L-1) with (2S)-2-aminobutanedioic acid (1.10--1.10-3 mol L-1) in constant ionic strength of 0.6 mol L-1 NaCl. We have determined the concentration region where we have found the clear solution and solid phase. The solid phase is analyzed by IR … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 4 · 31 Dec 2009 · 7,152 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleChromium (III) Removal and Recovery from Tannery Wastewater by Precipitation ProcessAbass Esmaeili, Alireza Mesdaghi nia, Reza VazirinejadChromium (III) salts are the most widely used chemicals for tanning processes, but 60-70% of total chromium salts reacts with the hides. In the other word, about 30-40% of the chromium amount remains in the solids and liquid wastes (especially spent tanning solutions). Therefore, the removal and recovery of the chromium content of these wastewaters are necessary for environmental protection … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 8,679 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTrend Analysis of Precipitation, Groundwater Level and Flow Rate Data by using Mann-Kendall and Sen's Slope Estimator Statistical Tests in the Petorca CommunerHéctor L. Venegas-Quiñones, Mark Thomasson, Pablo A. Garcia-ChevesichThis article analyses one of the most complex socio-environmental conflicts in Chile: The Petorca water crisis. Petorca has been experiencing a shortage of water for several years. The cause of these variations has not yet been completely analyzed and the problem has remained unchanged. This paper evaluates hydrology variables to identify, quantify and demonstrate the cause of water shortages in … …American Journal of Environmental Sciences, Vol. 15, Issue 6 · 10 Jan 2020 · 8,421 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Temperature and Precipitation on Global Mangrove Rhizophora Species DistributionAroloye O. Numbere, Gerardo R. CamiloClimate change influences the distribution of mangroves towards tropical or temperate regions of the world. We hypothesized that Rhizophora species organized along complex spatial and temporal temperature and precipitation gradient. To determine the affinity of different mangroves with climatic parameters, the response of eight Rhizophora species to seven climatic parameters (i.e., annual mean temperature, annual precipitation, maximum temperature of warmest … …American Journal of Environmental Sciences, Vol. 13, Issue 5 · 5 Oct 2017 · 8,259 accessesView PDFCite
