NO(3) concentration profiles were measured in the sediments of a meso-eutrophic lake with a newly developed microelectrode. The depth of penetration of NO(3) varied from only 1.3 mm in organic-rich profundal silty sediments to 5 mm in organic-poor littoral sandy sediments. The thickness of the zone of denitrification in the organic-rich sediments was <500 mum. Oxygen profiles measured simultane...

One research goal developed from conducted shallow water (SW) acoustic transmission experiments in sandy-silty areas [1] revealed a nonlinear power law frequency-dependent attenuation at lower frequencies ( ≤ 1 kHz ) consistent with results reviewed in [2-4] and the observations by the ONR-HEP program. The Biot Theory [5] predicts that the sandysediment frequency-dependent attenuation should be...

In geothermal reservoirs, hydrothermal distribution is significant. The most widely utilized reservoirs to date are those of systems, which systems where the reservoir contains steam, water, or a mixture both, depending on pressure and temperature reservoir. One geophysical method that enough map subsurface conditions determine 2-Dimensional Geoelectric using Wenner configuration. This aims stu...

Soil acidity is a major constraint that affect crop growth and production in larger aspect. The objective of the study to characterize different forms soil components relation properties. So, 14 georeferenced samples were collected from Jorhat Sibsagar district Assam. soils UBVZ Assam highly moderately acidic (pH range 4.27 5.34) with sandy loam silty clay texture high content organic carbon ra...

Evaluating the structure of soil prior to building construction is valuable in a large variety geotechnical and civil engineering applications. To built an effective framework for assessing strength stabilised soil, presented workflow includes complex approach simplex lattice design X-ray diffraction analysis structure. Different from traditional situ measurements, we propose statistical decisi...

The paper presents the test results from investigation of nature and mechanical behaviour mudbricks ancient mudbrick wall Eleusis in Attica, Greece. remains preserved to date site are some largest Small fragments were taken laboratory for experimental investigation. Testing included index tests toclassify soil material made of, mineralogical analyses their fines’ content, testing suitable mater...
