The human skin, its ageing process, and current anti-ageing cosmeceutical products
The skin is the largest, outermost, and one of the most important organs of the human body, acting as a protective barrier that encloses internal organs. Among its many crucial roles, it serves as a medium through which the body perceives the external environment. Skin ageing, which results from a systematic reduction in the number and size of cells in the layers that constitute the skin, is one of the earliest...

Calibration of the Hargreaves and Priestley-Taylor equations for estimating reference evapotranspiration in the Densu River Basin in Ghana
Reference evapotranspiration (ETo) defines the maximum evapotranspiration that can occur in a basin. Its accurate estimation is therefore very important in accurately estimating how much water is available in any Basin for use since the actual Evapotranspiration (AET) that occurs depends on the ETo estimated. AET is a parameter that is difficult to measure on the field and therefore is mostly estimated from ETo....
