Chitin, Chitosan and Glucan, Properties and Applications Authored by EM El Kady This review characterizes the most common natural polysaccharides and the presence of huge structural tendencies for the production of biologically active compounds, which have innovative characteristics and functions of different applications, especially in the field of biomedicine. such as glucan, chitin and chitosan (very basic) of living organisms and their properties involves solubility in different media, viscosity, behavior polyelectrolyte, forming polyoxysalt, visual ability to form films, chelation’s metals, and structural properties as molecular weight (Mw) and conformation. Their applications are also demonstrated, such as: biomedicine (antioxidant, anti-bacterial, anti-fungal anti-viral, hepatoprotective, cardiovascular, anti-hypercholesterolemia, anti-parasitic, anti-diabetic, detoxification, anti-tumor and immunomodulating), agriculture, food industry, textile industry, and paper making.

Oil Mill Wastewater and its Effects Authored by Serafina Andiloro Olive mill wastewater (OMW) is the liquid by-product generated during olive oil production. Different papers have discussed the effects of OMW discharge on soil characteristics, plant production and phytotoxicity. OMW are characterized by high organic load, concentrations of total suspended solids and phenolic compounds, and depends on the olives degree of ripening and the post-harvest, storage conditions, oil and grease. The relationship between soil and OMW is also in dependence of their quantity and qualitative chemical composition. It is noteworthing that the quantity and the quality of OMW is influenced by the olive oil extraction system. In a so called three phases system 50-70 L of lukewarm water are added per 100 kg olive fruits in the horizzontal centrifuge (decanter), whereas 0-20 L of lukewarm water are added per 100 kg olive fruits in a so called tw o phases system. As a consequence a three phases system prod...

  Smallholder Farmer’s Adaptation Strategy to Climate Change in The Case of Este Woreda, South Gondar Zone, Amhara Region, Ethiopia Authored by Beletech Kindu The main objective of this finding was identified adaptation strategies and factors that influence the probability of farmers to choose adaptation measurements in Estie woreda. Mixed research approach was used. Data was collected from 166 households and 5 agricultural experts through questionnaires and interview. The collecting data was analyses by using stata software and statistical software SPSS version 20. Adaptation strategies were considered use new crop variety, irrigation, soil-water conservation and planting trees for this study. The result obtained from multinomial logistics model shows that, adaptation strategies significantly influenced by agro-ecological zone, age, farm income, non-farm income, farm size, distance to the market, access of extension service and climatic information variables. Lack of skills and la...
