article image With the passage of time, under developing countries like Pakistan population is rising terrifically. Due to urbanization and mismanagement of natural resources, it has become a difficult task for agri-scientists to fulfill the food demand of the rising population. Due to the urbanization and industrialization, the agricultural lands are shrinking gradually. So, the vertical approach (to increase production per unit area) is the only option left for us. But on the other hand scarcity of…Read More

article image UNDER THE circumference of global warming and climate change, emanations of various gases seem to be played most destructive role in changing climate. In agriculture, so called chemical fertilizers or synthetic harmones are considered most effective candidates for instant availability of nutrients. However, complete utilization or uptake by plants is still a question. Not all amounts of available nutrients are used by the plant then where they go.Excess nutrients either deteriorate water quality…Read More

article image SOLAR TROUGH systems use linear concentrators of parabolic shape with highly reflective surfaces, which can be turned into angular movements towards the sun position and concentrate the radiation onto a long-line receiving absorber tube. The absorbed solar energy is transferred by a working fluid, which is then piped to a conventional power conversion system.Solar Trough Air ConditioningAnnual average energy consumed by HVAC (Heating, Ventilating, and Air Conditioning) systems contribute to…Read More

article image By Naseem SheikhSOOT FROM diesel exhausts and the burning of wood, agricultural waste and dung for heating and cooking causes an estimated two million premature deaths a year, particularly in the poorest countries. Scientists say that concerted action on these substances can reduce global temperatures by 0.5 degrees Celsius by 2050 and prevent millions of cases of lung and heart disease by 2030. There is no way to effectively address a climate change without reducing carbon dioxide, the most…Read More
