Biology Notes - Ecology and Eco-Systems Environment It is everything that surrounds you. It includes all natural living and non-living things that are included within the environment. All living organisms depend on the natural environment they live in. A natural environment is very different to a man made environment because a man made environment is heavily influenced by people whereas a natural environment is effected by people by a very small amount.

influence many health problems. Some of the related problems due to global warming are death to heat waves and other climate changes‚ and infectious diseases. With the atmosphere temperature rising‚ we all will be at risk. The climate not only harms our bodies‚ it can also harm our crops and waters. Floods and droughts associated with global warming can undermine our health in other ways. The heat that is produced can damage our crops. The temperature will allow our crops to be infected

SIMULATION STUDIES ON GAX BASED VAPOUR ABSORPTION REFRIGERATION SYSTEM FOR COMBINED DRYING AND STORAGE APPLICATIONS R Sivakumar‚ R Saravanan and Alberto Coronas Extended Abstract India is the second largest producer of fruits and vegetables in the world. In 2010-11‚ fruit production stood at 74.877 million tonnes and vegetables production at 146.554 million tonnes. On the other hand 18% of fruits and vegetables from India are going to waste for want of adequate storage facilities. The amount

HEAT TRANSFER OF BALL BEARING Muhammad Sabry Anwar Bin Sazali 2011297756 BACKGROUND A steel ball bearing at 1200K is need to be quenched for 30 seconds in water that is maintained at a room temperature of 300K after heating them to a high temperature of 1000K. However‚ it takes time to take the ball from the furnace to the quenching bath and its temperature falls. If the temperature of the furnace is 1200K and it takes 10 seconds to take the ball to the quenching bath‚ is less time needed

CHAPTER 1 Introduction Some farmers who don’t have irrigation system‚ plant rice during rainy season so‚ they have the difficulty of drying their grains after harvest. Aside from these‚ drying the grains under sunlight takes longer time‚ more effort in handling to the drying site‚ scraping or ricking‚ guarding from animals‚ collecting after drying‚ and another is that the possibility of the grains to be mixed with stones‚ leaves of tree‚ and dust in road drying and field drying. There are many
