Chemical profiling of decomposition odour is conducted in the environmental sciences to detect malodourous target sources in air, water or soil. More recently decomposition odour profiling has been employed in the forensic sciences to generate a profile of the volatile organic compounds (VOCs) produced by decomposed remains. The chemical profile of decomposition odour is still being debated wit...

In predicting wheat (Triticum aestivum L.) phenology, logic suggests that basing thermal unit accumulation on near-surface soil temperature should give a better representation of shoot apex thermal unit accumulation than air temperature until internode elongation raises the apex above the soil surface. A study was undertaken to determine if predictions of winter wheat phenology are improved whe...

Over the past several years, considerable resources have been expended to develop sensors capable of detecting buried landmines by sensing the vapors evolving through the soil and into the air above the mines. An effort was also made to characterize the vapor signatures of buried mines. This was done to provide the sensor developers with information on the qualitative and quantitative nature of...

population growth rating, high food demand, and land resource challenges have led to more serious studies of production factors especially the scarce water and soil resources. one of the most basic data items in land resources is the soil map. therefore, in the process of the present research for preparing soil maps of some soil quality indices at the faculty of agriculture experimental field (...

Bench-scale laboratory experiments were conducted to evaluate the effectiveness of air stripping for in situ remediation of benzene-contaminated soils. Several parametric studies were performed to evaluate the effect of soil grain size, air injection flow rate, and air inlet temperature on the benzene recovery efficiency. An increase in soil grain size produced a significant increase in benzene...

Shear strength of aggregates and the bulk soil matrix in two Haploxeroll of central Chile was assessed in order to determine: (1) the effect of previous tillage on shear parameters between aggregates and in the soil matrix and (2) the effects of structure development on differences between dry-wet mechanical parameters. Undisturbed soil cylinders and single aggregates (0-10 cm layer) were colle...

significant damages incurred across lebanon during the july 2006 war encompassing the destruction of road networks, bridges and overpasses as well as a vast number of dwelling units. it is anticipated that reconstruction works after the war shall unavoidably create a newly founded demand for natural resources, most notably primary and secondary construction material. this paper assesses the war...
