Abstract:
A predictive approach has been presented to calculate the standard enthalpy of formation of pure compounds based on a quantitative structure–property relationship technique. A large number (1692) of pure compounds were used in this study. A genetic algorithm based on multivariate linear regression was used to subset variable selection. Using the selected molecular descriptors an optimized feed forward neural network was presented to predict the ΔHfo of pure compounds.

The behaviour of pig liver esterase (PLE) in the presence of some commonly use alcohol and ketone cosolvents was examined. Methanol, ethanol and 2-butanone were found to be potent inhibitors of PLE. At low concentrations, acetone accelerated the rata of PLE catalysed hydrolysis, but is also inhibitory at higher concentrations. The effects of alcohols as product inhibitors

Abstract:
The employment of enzymes and whole cells has been important in many industries for centuries. However, it is only in the last 30 years that the use of enzymes for the synthesis of high-value fine chemicals has enjoyed increasing popularity. In fact, esterases and lipases are used almost routinely these days to provide optically active building blocks for the construction of imaginative new routes to chiral target molecules. The major topic of this work describes the utilization of enzymes (namely lipases) in the synthesis and modification of natural and non-natural compounds. Chapter 1 outlin

Abstract:
Anticancer chemotherapeutic treatment using single dose has been limited due to drug resistance and potential metabolic degradation. For instance, high-dose tocotrienols undergo metabolic degradation that limits the availability of therapeutic dose thereby limiting the potency in vivo. Combined treatment of tocotrienols at low dosage has been suggested as alternative to circumventing this limitation. This study was designed to investigate the cytotoxic effects and subsequently the apoptotic mechanisms of individual doses and combined treatments at lower dosages of tocotrienols (delta and gamma

In the Cesar Department in Colombia, sustainable agriculture faces critical challenges despite its thriving livestock sector. Extensive cattle ranching and poor soil management worsen soil conditions. Additionally, significant environmental concerns arise from the substantial discharge of wastewater in the dairy processing industry. This study aims to valorize biosolids derived from wastewater during dairy plant disinfection to enhance sustainable livestock production. It explores the use of biosolids as the primary matrix for creating composted compounds and biopolymers for agricultural purpo

Abstract:
Mixed surfactants of cationic and nonionic surfactants, cetyltrimethyl ammonium bromide (CTAB) and Triton X-100, were employed in the admicellar polymerization to replace the use of pure CTAB. Effect of the molar ratio of CTAB to Triton X-100 and the adsorption structure of surfactants, monolayer and bilayer, were investigated on the admicellar polymerization compared with the polymerization using only CTAB in terms of the compatibility between rubber and silica. Results indicated that the silica modification by the nonionic surfactant was successfully used to modify rubber compound. The prope

Abstract:
The general objective of this BARD project focused on rationally designed insect neuropeptide (NP) agonists and antagonists, their application for the characterization of the mechanisms of action of the pyrokinin/PBAN (PK-PBAN) family and the development of biostable, bioavailable versions that can provide the basis for development of novel, environmentally-friendly pest insect control agents. The specific objectives of the study, as originally proposed, were to: (i) Test stimulatory potencies of rationally designed backbone cyclic (BBC) peptides on pheromonotropic, melanotropic, myotropic and

Abstract:
To investigate the effect of microwave cure and thermal cure in silicon carbide whisker (SiCw) filled in polybenzoxazine (PBZ) composite on its corresponding thermal and mechanical behaviors. SiC whisker is thus, used as a filler of the polybenzoxazine to enhance the microwave absorption capability of the molding compound and to reinforce the material. The experimental results reveal that the benzoxazine resin (BA-a) was hardly cured at a high power of 1 kW for 15 min. However, with a relatively low content at 4% by weight SiCw, the benzoxazine resin was found to be cured relatively well. Ther
