English Language Institute

The design of a hybrid electric power generation system utilizing both wind and solar energy for remote area is today’s need. The system has two basic components – one for generation of electricity through Solar Energy and another one for generation from Wind Energy. Even in the case of absence of either of the two sources, the other remaining source could be used to supplement the absence of the former. The power from wind current can be extracted using a vertical axis turbine. Vertical axis turbine is capable of extracting power form wind regardless of the direction of flow. The …

Are Conditions Right On Other Planets For The Existence Of Life As We Know It?, Nuri Park

English Language Institute

Understanding the origin of life is one fo the fundamental knowledge required to find life on extraterrestrial celestial. Among numerous phenomena that are driven by bio-molecules, self-assembly of the cellular membrane is considered as the most basic process in the origin of life. In water dominant environment of standard pressure and temperature, molecular interaction (Van der Waals force) among water molecules and phospholipids forces phospholopids to form lipid bilayer structure which is the proto structure of the cellular membrane. However, self-assembly of phospholopids in extremely pressurized wet environments has never been explored. Since liquid water in the solar system has …

Digital Mapping Of Togo’S Soil Fertility: Savannah Region, Aminou Saibou Jul 2020

Digital Mapping Of Togo’S Soil Fertility: Savannah Region, Aminou Saibou

English Language Institute

A soil assessment was carried out in the savannah region of Togo in 2018, aiming at drawing the digital map of Togo’s soil fertility and making fertilizer recommendations. Soil samples were taken from geo-referenced GPS points and were analyzed for parameters such as water pH, Organic matter, available phosphorus and exchangeable potassium. Thematic maps have been drawn using an ArcGIS package. The results showed that the soils of the Savannah region in Togo are mainly (84%) not very acidic (pH = 5.5 to 6.5), overall poor to very poor (84%) in organic matter (<2% OM), essentially poor to very poor (86%) in available phosphorus (<15 mg/kg of soil) and mostly very poor (87%) in exchangeable potassium (<90 mg / kg of soil). These results allowed the agricultural research institute of Togo to make fertilizer use recommendations and to develop, in partnership with Morocco, a digital platform (fertitogo.tg ) for decision making in crop fertilization.
