A large amount of avocado is produced every year, and processing of avocado re-sults in the production of large quantities of peel, which is usually disposed as waste without any further application. Avocado peel is a rich source of diverse phy-tochemicals known as he-alth-promoting compounds, and these compounds can be used to produce high eco-nomic value products. How-ever, the amount and com-position of phenolic com-pounds vary regarding dif-ferent factors, such as level of ripening and maturation, growing conditions and the country of origin. Phenolics within avocado peel have been reported to exhibit an-tioxidant, antimicrobial and anti-inflammatory effects, and associated with exten-sive health benefits. Thus, it is of great importance to recover these compounds from the peel for usage in food and health industries. This review focuses on the phytochemical compounds together with main factors influencing their types and amounts in avocado peel, and the possible utilisation of this by-product in the food, pharmaceutical and some other industries.

Pharmacological Potential

Our present study focuses on the evaluation of the analgesic, anti-inflammatory and healing activity of Withania frutescens L. The anti-inflammatory result has an inhibition percentage of 78.87% ± 7.08 at 450 mg/kg and 75.14% ± 6.39 at 400 mg/kg and 89.75% ± 3.44 for diclofenac (1%). When applied locally, the 10% cream has an inflammation inhibition of 96.87% ± 5.85 and 76.14% ± 7.88 for the 5% cream with 89.87 ± 6.20 of reference (Indomethacin). The abdominal contractions of rats treated with the root extract are significantly lower than those of the control group that received only physiological NaCl solution, with 41.20 ± 2.30 for the extract and 82.20 ± 5.04 for NaCl and 53.40 ± 4.94 for the reference. The healing activity of the studied extract records a percentage of contraction of about 93.20% ± 3.36 (Extract 10%), 84.50% ± 3.84 (Extract 5%), 48.47% ± 2.15 (control) and 81.88 ± 2.24 for the reference.

Background: Tea (Camellia sinensis, Theaceae) is the second most consumed beverage in the world. Green tea is the least processed and thus contain rich antioxidant level, and believed to have most of the health benefits. </p><p> Methods: We commenced to search bibliographic collection of peer reviewed research articles and review articles to meet the objective of this study. </p><p> Results: From this study, we found that the tea beverage contains catechins are believed to have a wide range of health benefits which includes neuroprotective, anti-inflammatory, antiulcer, antiviral, antibacterial, and anti-parasitic effects. The four major catechin compounds of green tea are epigallocatechin (EGC), epicatechin (EC), epigallocatechin gallate (EGCG), and epicatechin gallate (ECG), of which EGCG is the major constituent and representing 50-80% of the total catechin content. And also contain xanthine derivatives such as caffeine, theophylline, and theobromine, and the glutamide derivative theanine. It also contains many nutritional components, such as vitamin E, vitamin C, fluoride, and potassium. We sum up the various green tea phytoconstituents, extraction methods, and its medicinal applications. </p><p> Conclusion: In this review article, we have summarized the pharmacological importance of green tea catechin which includes antioxidant potential, anti-inflammatory, antimicrobial, anticancer, antidiabetic and cosmetic application.

AbstractCarbon black-filled polymer composites were investigated as sensing materials for organic liquids. Polypropylene and polystyrene which were selected as matrices and various amounts of carbon black were considered as the main factors influencing sensitivity of the composites in view of the percolation theory. Disposable filaments were produced of these materials. Change in their electrical resistivity was measured upon immersion in benzene, toluene, xylene, ethylbenzene and their mixtures. It has been found that studied materials were sensitive to the composition of liquid mixtures of organic solvent. Relationships between the filament response and volumetric fraction of the components were presented. The studied materials have shown promising sensing properties, which suggest their applicability for identification and quantification of multicomponent organic liquids.

Main Factors

The Saudi Ministry of Education has recently begun to allow all Saudi families to enroll their children in international schools. The international curriculum offered by such schools represents a notably different choice compared with Saudi traditional public and private schools, both of which teach the same state-mandated curriculum. As a result of the change, there has been a surge in demand for international education; the number of schools has increased rapidly, and there has been a steady “student leak” towards them and away from traditional schools. Little is known about why Saudi parents choose to enroll their children in international schools. We explored this question by surveying 431 Saudi parents of children attending such schools to identify the main factors contributing to their choice. Although all factors examined were important to parents, curriculum and overall school quality emerged as the most important; socioeconomic status was not influential in their decisions.

This study uses a diagnostic and multidisciplinary water governance assessment framework to examine the main factors influencing water cooperation on the shared Mountain Aquifer between Israel and Palestine. It finds that effective cooperation between Israel and Palestine is unlikely in the foreseeable future if both parties persist with the business-as-usual approach. What constrains the two parties from achieving consensual agreement are political tensions, the constraints of current technology, the different perceptions of the value of the shared water, the mistrust between the two parties, the lack of external enforcement mechanisms, and the impacts of the domestic political environment.

Based on the generalization of research results on the processes of obtaining SiO2 sols using tetraethoxysilane and ethyl silicates, the main factors influencing the elasticity of silica coatings on cotton fabrics and their fire-retardant properties are considered. The possibility of forming covalent bonds between the functional groups of cellulose, gel coating and flame retardant layer is considered, which explains the strong fixation of a thin layer of coating on the fibers of the fabric and improve its fire protection. The use of the developed compositions for fire-retardant elastic coatings based on ethyl silicate allows to increase the time of complete burning of cotton from 30s (untreated fabric) to 600s (treated with binary coating).
