51902Optimization and computational logic
This book software package uniquely integrates logic and operations research. Its broad coverage provides concepts, templates, and the tools for the task of attacking difficult problems which are repeatedly encountered in decision making. The first part deals with linear programming and the second with search techniques for combinatorially hard problems. The applications discussed include product mix problems, pattern recognition, classical and probabilistic logic, financial planning, and expert systems.
51903Optimization of Citrus limon peel extraction, determination of main chemical components and effectiveness in repellency against Aedes mosquito dengue fever vector
In this study, we collected the discarded Citrus limon peel source in Gia Lai province to utilize as a material to build an optimized extraction process with the following criteria: extraction solvent, solvent/sample ratio, extraction temperature, and extraction time. The results showed a stable extraction process with a maximum extraction efficiency of 4.02%, at 40°C, for 3 hours, with two extraction times using 95% ethanol for solvent. Using GC/MS method, the determined limonene content accounted for 12.2% of the extract. The Citrus limon peel extract exhibited potency against Aedes aegypti (arbovirus vector) at a concentration of 0.01 mL, with protection time of 70 minutes and biting percentage of 0.9%, compared to negative control with statistically significant (P < 0.05). The above results correspond with the most recent publications about the effects of mosquito repellence of certain plant-based essential oils. This study has proven that Citrus limon peel in this locality signifies a promising candidature for future studies regarding its main active compound, limonene, in the control of dengue-transmitting vectors. Therefore, Citrus limon peel extract brings hope to develop new mosquito repellency products in the future.
