The kinetics of the reactions between [Ni(bipy)(COD)] and bicyclopropylidene (bcp), dicyclopropylacetylene (dcpa) 1,4-dimethoxy-2-butyne (dmbu) were investigated using stopped-flow techniques. Similar to previous studies results support an associative mechanism (activation parameters for bcp: ΔH#=46±2 kJ ⋅ mol−1 ΔS#=−69±8 J K−1) therefore allowed postulate a more general reaction pathway. produ...

SELF-ASSEMBLY OF BLOCK COPOLYMERS BYSOLVENT VAPOR ANNEALING, MECHANISM ANDLITHOGRAPHIC APPLICATIONS FEBRUARY 2014XIAODAN GUB.S., NANJING UNIVERSITYM.S., UNIVERSITY OF MASSACHUSETTS AMHERSTPh.D., UNIVERSITY OF MASSACHUSETTS AMHERSTDirected by: Professor THOMAS P. RUSSELL Block copolymers (BCP) are a unique class of polymers, which can self-assembleinto ordered mic...

Non-clausal refinement of Boolean Constraint Propagation inference procedure for classical logic, called P-BCP, is introduced within a new knowledge representational formalism of polarized formulas. P-BCP is a sound, incomplete, and linear-time inference procedure. It is shown that P-BCP can be adopted for tractable reasoning in a number of non-classical logics (including some modal and finitel...

This study compares a traditional agricultural approach to minimise N pollution of groundwater (incorporation of crop residues) with applications of small amounts of biodiesel co-product (BCP) to arable soils. Loss of N from soil to the aqueous phase was shown to be greatly reduced in the laboratory, mainly by decreasing concentrations of dissolved nitrate-N. Increases in soil microbial biomass...

Radiographs and synovial fluids from 66 knees representing 59 patients with symptomatic osteoarthritis were evaluated to determine the pattern of radiographic abnormalities associated with basic calcium phosphate (BCP), calcium pyrophosphate dihydrate (CPPD), or both crystals together. Crystals were found in 71% of fluids. In general, CPPD crystals correlated with patient age, while BCP crystal...

This study explored the feasibility of lignin based biofuel co-product (BCP) for subgrade soil stabilization, and more specifically, its impact on Hot-Mix Asphalt (HMA) pavement performance using the Mechanistic-Empirical Pavement Design Guide (MEPDG). The HMA pavement systems with BCP stabilized subgrade under different traffic and climate conditions were modeled using mechanistic based damage...

Authors have found out that bamboo charcoal powder (BCP), which is prepared from bamboo wastes by pyrolysis at low temperatures, is very useful as a carrier for the thermal stabilization of proteins. Hen egg white lysozyme (HEWL) and α-chymotrypsin (CT) were effectively adsorbed onto BCP. The thermal stability of BCP-adsorbed HEWL was strongly dependent upon the adsorption conditions such as so...

Increasing, the colloid osmotic pressure (COP) of blood cardioplegia (BCP) may reduce myocardial edema and preserve cardiac function following cardiopulmonary bypass (CPB). The purpose of this study was to quantify the effects of albumin (ALB) supplementation on cardioplegia COP through an in vitro analysis. A self-contained cardioplegia delivery system administered supplemental ALB to four BCP...

background more than two billion people have been exposed to hepatitis b virus (hbv) worldwide. furthermore, four hundred million of them are infected with chronic hbv infection. the predominant mutation of the precore region involves a g to a change at nucleotide1896, which creates a premature stop codon at codon 28. two mutations of a1762t and g1764a are reported as the most prevalent mutatio...

At present, there are no tools available for objectively evaluating the effectiveness of a bridge construction plan (BCP). As a result, bridge designers predominantly evaluate BCPs by considering only the short-term economics (i.e., construction costs). Other significant issues for project success, like safety, accessibility, and impact on local community, are evaluated based on subjective judg...
