It is a common experience to walk in urban park‚ then few steps away‚ you just turn the corner‚ pass through lined tall buildings in a narrow street paved with asphalt and you clearly feel that the temperature is higher than in the park. Or maybe‚ you can recall one day in your life when the city was really hot‚ that you decided to spend some time in a shading park where you found some relief. Most of you didn’t know but you experienced what in climate science is called the urban heat island effect

Introduction: Agriculture is an art‚ science and industry of managing the growth of plants and animals for human use. In broad sense‚ agriculture includes cultivation of the soil‚ growing and harvesting the crops‚ breeding and raising livestock‚ daring and forestry. Modern agriculture is engineering and technology based. Therefore‚ mechanization has eased much of the back breaking toil to the farmer. Agriculture is the backbone of economy of most of the countries of the world. About 48 percent

Chapter one Introduction In industrial processing water is used in numerous applications requiring likewise different qualities of water. Examples of different use are cooling water‚ water for rinsing and chemical production‚ boiler feed water‚ purified water‚ water for injection‚ just to mention a few of those. On a chemical site or within a factory commonly a central water production unit is providing the basic amount of water in several qualities. These water supply units are using more and

MULTICELLULAR ORGANISMS The complex multicellular animals and plants perform many different activities in order to exist. More energy is invested in all organisms for their accumulation and distribution of food‚ release of waste matters‚ movement‚ reproduction‚ and coordination of these activities. The different organisms have specialized tissues‚ organs and organ systems that work together for the good of the organisms. Thus the well-being of the whole organism depends on the integration

water in the world ’s oceans‚ lakes‚ etc. to warm and evaporate. As the water is heated‚ it changes its phase from liquid to gas. This gas is called water vapor and this process is called evaporation. When plants give off water vapor‚ it’s called transpiration. When water evaporates‚ it rises into the cooler air‚ collects‚ and forms clouds. There‚ the water vapor molecules cool down and change back into liquid water. This is called condensation. As more and more water vapor cools into the clouds‚

activities of such areas. Modern systems of defining aridity tend to be based on the concept of water balance‚ the relationship that exists between the input of water in form of precipitation‚ the losses arising from evaporation and transpiration (evapo-transpiration) and any changes in storage (soil moisture‚ groundwater‚ etc). By definition‚ in arid areas‚ there is an overall deficit in water balance over a year and the size of that deficit determines the degree of aridity. Extremely arid areas

devalue chlorophyll in the old leaves. The uptake of magnesium by Giant Miscanthus is by two main processes. Diffusion which moves magnesium ions from high concentration zones to lower concentration zones and by passive uptake which is driven by transpiration stream. Calcium plays an essential role in plant growth and nutrition. As calcium helps maintain chemical balance in soil it reduces soil salinity and also improves water penetration. Calcium also neutralizes cell acids and plays a role in the

Anatomy of Flowering Plants Tissues A tissue is a group of cells having a common origin and usually performing a common function. Based on cell’s capability to divide‚ tissues are classified into two main groups which are as follows: 1. Meristematic and 2. Permanent tissues. Meristematic Tissues: Cells in the meristematic tissue are capable of dividing. Meristematic tissues are found in those regions which need to grow continuously. For example‚ root tips and stem tips contain meristematic
