The geology, sediment and soil studies are important due to its significant impacts on agriculture, mining, constructions materials, industries, environment, ground water percolation, air pollution, surface pollutions, earthquakes geo-hazards in Afghanistan. In this research, we studied petrography, Sediment, tectonic structures, fraction selection by using hydrometer, sieving analysis, geologi...

Abstract Hydrometers are widely used in industry for liquid density measurement. It is important to achieve rapid and high accuracy calibration hydrometers. Based on the Archimedes principle, a fully automatic hydrometer system NIM was designed using Cuckow’s method. The of n -tridecane (C 13 H 28 )is calibrated with 441 g high-purity fused silica ring as solid standard. buoyancy measured by st...

Different techniques have been developed in the 20th and 21st centuries to address study of particle size distribution fine materials. Most these are based on gravitational sedimentation processes. The modern method used this research bases measurement change pressure aqueous medium caused by progressive settling particles. materials were evaluated within compare results integral suspension (IS...

m) by wet sieving from the clay and silt (particles 50 m). The sand fraction is determined by drying and Determination of soil particle-size distribution (PSD) by sieving, weighing the material remaining on the sieve. The silt hydrometer, and pipette methods as well as by laser diffraction (LD) suffers from inherent flaws, mainly due to the difficulty in defining and clay fractions are then det...

Three manure agitation procedures were examined in this study (vertical mixing, horizontal mixing, and no mixing) to determine the efficacy of producing a representative manure sample. The total solids content for manure from gestation pigs was found to be well correlated with the total nitrogen (TN) and total phosphorus (TP) concentrations in the manure, with highly significant correlation coe...

Climatic conditions and in situ lithology govern the hydrogeological behaviour of badland surfaces in western Canada. Based on field observations, samples representing three distinct surfaces in the Avonlea badlands (60 km SSW of Regina) of Saskatchewan were collected. The influence of erosion on the engineering properties of this typical indigenous badland profile was investigated by measuring...

Colostrum samples from 88 Jersey cows were analyzed for concentrations of IgG, IgM, IgA, total solids, specific gravity, and N fractions. Colostrum (50 ml) was sampled from each cow as soon as possible after parturition, and specific gravity was determined immediately using a hydrometer. Samples then were frozen prior to analysis of Ig, fat, and N fractions. Mean concentrations of IgG, IgM, and...
