The important characteristics of polymer/clay nanocomposites are stability, barrier properties and in the case of polyvinyl chloride also plasticizer migration into other materials. Therefore, the permeation properties of polymer/clay nanocomposites are discussed in this paper. The attention was focused to the polyethylene (PE) and polyvinyl chloride (PVC). Natural type of montmorillonite MMTNa...

The method of encasing the stone column with a proper type geosynthetic material is widely used technique to provide required lateral confinement and avoid dispersion granular into soft clay. Along improved ultimate load capacity reduced settlement bulging, encasement preserves easy drainage ability columns. This paper presents finite element analysis results hypothetical embankment on soil dep...

Incubation experiment was conducted on four soil types in Nigeria using cattle dung (CD) at the rate of 2.5g/kg soil ( 5 t ha), Urea fertilizer at the rate of 0.1g/kg soil ( 200 kg ha ) and cattle dung (2.5g/kg soil) combined with Urea 0.05g/kg soil (100 kg ha) as treatments. The objective of the experiment was to compare the rate of OC, NH4 – N, NO3 – N and available P release on soils selecte...

Interest rate risk measurement and management of non-maturity deposit balances presents a challenge for practitioners academic researchers as well. The paper provides review several methodological approaches focusing on the area savings accounts sensitivity modeling estimation. proposed models are tested Czech banking sector dataset providing mixed results regarding cointegration type generally...

Abstract Aerogel is a nano-porous material with significant thermal insulation properties and good candidate for improving the performance of traditional materials energy efficiency in buildings. It therefore gaining more interest construction industry researchers are carrying out investigations incorporating granular aerogel into bricks. The aim present paper experimental investigation influen...

ABSTR ACT: In a laboratory investigation, the effect of natural sunlight and UV light exposure on dissipation of fipronil insecticide from two soils (clay loam and sandy clay loam) and the effect of pH on the persistence of fipronil in aqueous medium were studied. Dissipation of fipronil insecticide under sunlight followed biphasic first order kinetics in both soils. The half-life of the insect...
