Anatomy and Physiology Anatomy refers to the form and structure of the body while physiology refers to the functions of the forms and parts of the body. Some of the systems which maintain the body include, circulatory system, reproductive, respiratory, nervous and digestive system. Circulatory System This system involves all the organs and tissues which are concurred with the movement of materials from one part of the body to another where they are either used or removed. These organs and tissues include the heart, the blood and the blood vessels....

Farm Mechanization refers to the development and use of machines that can take the place of human and animal power in agricultural processes. The mechanization of agriculture that took place during the 20th century led to major changes in how farmers plant, irrigate and harvest crops. Combines, tractors, harvesters and other machinery have enabled farmers to increase their production while relying less upon an extended labour force. The term “mechanization” is used to describe tools, implements and machinery applied to improving the productivity of farm labour and of land; it may use either human, animal or motorized power, or a combination of these. In practice, therefore, it involves the provision and use of all forms of power sources and mechanical...

Power is defined as the rate of doing work or the rate of expenditure of energy. Farm power is one of the most expensive and critical inputs when growing a rice crop. Humans, animals and machines are all used as sources of power in agriculture production. When undertaking different operations on a farm, a certain amount of work is required to complete the task. Farm power can be obtained from the following sources: Human Power Mechanical Power Animal Power Electrical Power Solar Power Wind Power Water Power Biogas Human Power...

Farm tools are implements and equipment used for farming purposes. See below the list of farm tools and their functions. Spade – This is a basic farm tool used for digging, planting, hoeing, shovelling, and cutting lawn edges. Long-handled spades have more leverage when digging, but the short-handled spade encourages the user to grip the handle lower down – more under the load, and to use the leg muscles more. The T-piece, or D-piece on the short-handle type, gives some twisting leverage – a help when turning over spadefuls of soil during digging....

Basic Emission Theory If we provide energy to an electrode then the electrons in the outermost shell of the atom of the metal gain enough energy to eject from the surface of that metal or electrode. This process is called electronic emission. The term emission means the dislodgement or displacement of electrons from a material with the intention of directing such emitted electrons to a predetermined position or object. When electrons are displaced from the outermost layer of an atom of any material, they form free electrons and emission takes place. The continuous movement or drifting of such free electrons constitutes the flow of electric current. These free electrons also form the basis of operations of both electronic and electrical...
