Using a source of 19th century US state prison records, this study addresses European-American stature variation. The most commonly cited sources for stature variation are diets, disease, and work effort. However, vitamin D is also vital in human statures and health. This paper demonstrates that...

This paper reviews the potentials of photovoltaic system technology as a viable alternative to the 100% use of imported fossil fuel for electricity generation in Northern Cyprus. It presents an experimental investigation of two installed 100Wp photovoltaic systems design in block A building of...

Nineteenth-century U.S. state prison records contain information on European-American stature. The most commonly mentioned reasons for stature variation were diets, disease, and work effort. The statures of whites were positively associated with direct sunlight. Stature and insolation were...

An alternative method of heat extraction from salt gradient solar ponds to solar collector is investigated with the aim of night operation for solar chimney power system. Some details of the combined power system integrated with solar ponds and solar chimney power system are also provided. Using...

This article presents the critical design specifications and field performance of an improved solar tunnel dryer for drying aonla plup. The dryer consists of an ultraviolet stabilised semi-transparent polythene sheet of 200-micron thickness with loading capacity of 1 ton of aonla in a batch....

Most conventional solar thermal radiation concentrators have some sort of symmetry which allows them to concentrate solar thermal energy for their operation. We report a new system that utilises the symmetry of a cone and a cylinder combination to simulate the concentration of solar radiation on...
