The research was carried out to ascertain the effect of three chloroacetanilide herbicides, alachlor, butachlor and pretilachlor on soil microbial biomass growth and activity. Laboratory experiments were performed in a silty clay loam soil to relate changes of soil enzymatic activity to the herbicide persistence under laboratory condition up to 42 days at(More)
Dynamically optimized sequential experiments (DOSEs) to estimate risk preferences start with a distribution of beliefs about risk preference parameters, and a set of questions, then dynamically choose questions that maximizes information gain considering previous answers. Applying the method to the 10-question set of Holt and Laury (2002) and the(More)
Energy is the key input for technological, industrial and socioeconomic development of a Nation. The technology of deriving energy from renewable bio-resources has been receiving much attention globally. Jute stick, agro-waste and jute caddies, mill waste are potential raw materials for generation of bio-energy. Jute stick, the woody biomass constitutes(More)
The aim of this study was to investigate the feasibility of using visible near-infrared (VisNIR) diffuse reflectance spectroscopy (DRS) as an easy, inexpensive, and rapid method to predict compost enzymatic activity, which traditionally measured by fluorescein diacetate hydrolysis (FDA-HR) assay. Compost samples representative of five different compost(More)
Introduction: A new class of hernia repair devices has been created through the combination of optimally processed extracellular matrices (ECM) and select monofilament polymers. The resulting Reinforced BioScaffolds (RBS) are designed to exceed physiological forces and remodel in response to these forces, with the goal of providing a load sharing construct(More)
