Assessment of Wind and Solar Hybrid Energy for Agricultural Applications in Sudan.

In addition to zero-carbon generation, the plummeting cost of renewable energy sources (RES) is enabling the increased use of distributed-generation sources. Although the RES appear to be a cheaper source of energy, without the appropriate design of the RES with a true understanding of the nature of the load, they can be an unreliable and expensive source of energy. Limited research has been aimed at designing small-scale hybrid energy systems for irrigation pumping systems, and these studies did not quantify the water requirement, or in turn the energy required to supply the irrigation water.

Concrete mix design and aggregate tests data between 2009 and 2017 in Sudan.

Over 1000 mix designs data and more than 1400 fine and coarse aggregates tests results data were collected for the previous 10 years in Sudan. The data was organized into spreadsheets creating a data base useful for future studies. The data includes mix designs proportions in terms of cement content, water, fine and coarse aggregate in addition to the used admixtures.
