The dates are used to prepare several food products, among which the Btana is a best conservation form commonly practiced in the South-west area of Algeria. The peasants add during its preparation one or more aromatic herbs according to the choice and the areas. The present research aims relates to the study of the effectiveness of the methods used from the microbiological quality point of view and the determination of the effect of the plants added during the Btana preparations, for that...
Wind and solar resources are diluted and intermittent on the earth; their combination allowed increasing their availability and stability. At great scale, the use of Solar Chimney Power Plant (SCPP) technique constitutes a promising alternative to fossil fuel for generating electrical power particularly in rich regions of natural resources such as solar, wind, terrain, built material,water…etc.). Recently, various research works investigate the design and optimization of thesesystems u...
Date by-products constitute the principal food for the oasis populations in Middle East and North Africa. Dates contents consist of 70 to 80% of reducing sugars, and do not require an intensive energy and labour for thermophysical pre-treatment. They can serve as a good feedstock for bioethanol generation through fermentation and distillation. Algeria is among the top sixth producers of dates in the world with more than 250,000 tons/year; from these, more than 30% can be lost for dif...
Every year, more than 236,807 tons, equivalent to 30% of date-palm fruits produced in Algeria, is lost during picking, storage, and commercialization processes. Gasification of this huge biomass can generate biogas such as bioethanol, biodiesel, gasoline and other useful substances. Bioethanol is becoming the main biofuel produced by chemical synthesis or anaerobic fermentation from biomass and is significant for industrial development, investment, and use. It is eco-friendly, moderately cost...
