CHILD IMMUNISATION

Most diseases are infectious, they can be passed on from one person to another. Scientists study the structure, mode of life and life cycle of organisms responsible for transmitting diseases. They also study the method of transmission of diseases. These studies helps scientists to work out ways of preventing the spread of these diseases and of protecting people from contracting them, one method of preventing diseases is immunisation.
Immunisation is a method of preventing diseases by injecting or taking into the body specially treated disease causing organisms or their products. When such materials enter the human body, the body reacts as if the disease causing microbes are actually present, but the person does not fall ill. The body produces substances called antibodies destroy the disease causing microbes or their harmful products. Excess antibodies remain in the blood and if the individual comes in contact with any of the given diseases organisms, the antibodies stop the disease from developing. Children are usually immunized against seven diseases that commonly cause preventable death. These are poliomyelitis, measles, tuberculosis, tetanus, yellow fever, whooping cough and diphtheria.
Vaccination inoculation and immunisation may be used to mean the same thing. Experts, however, make a clear distinction between them. Vaccination involves making some cuts on the skin with a sharp knife or razor before introducing the treated, weakened disease organisms through the cuts. Inoculation usually involves injecting the treated organisms into the body. Immunisation covers all method of introducing treated weakened, disease causing organisms into the body, including introduction by mouth. Immunisation of the child start during the pregnancy. The mother is to be given tetanus vaccine at the antenatal center.

Natural soil

Natural soils are influenced by rainfall and temperature,heavy rain causes the soil to become leached. High temperatures increase the rate of decomposition of organic matter in the soil, thereby lowering its humus content. Thus, climatic conditions tend to produce poor soils in the tropics and rich soils in the temperate regions. Besides climate and vegetation, the parent rock material also contributes to the quality of the soil. For example volcanic rocks tend to produce fertile soils. Laterite, a red soil which is a product of leaching, is commonly found in the tropics. It is composed mainly of iron and aluminium compounds,and poor in humus and essential plant nutrients, such as phosphorus, nitrogen and potassium. The black and brown soil of the temperate grasslands are the world's richest soils, with a high mineral and humus content. The light coloured desert soils tend to be very rich in minerals but have a low humus content. Mainly the soils ar...

READING AND UNDERSTANDING

All reading is geared to understanding. There would be no point in reading if we did not understand what we are reading. However there are many different obstacles in the way of easy understanding of a passage. It is your task as a reader to actively seek to break down the barriers to understanding. One block to understanding is caused by references in the passage to things that are outside it. Pronoun are the first examples of words that refer to people and objects. Sometimes, it is easy to follow the reference at other times, it is more difficult. Look at the opening sentence of the passage you've just read that begins this way "She was waiting for us:small, dowdy, dirty..." Who was waiting? Who was the person waiting for? (Perhaps you would also like to know why she was waiting.)Answers to these questions will surely help you to understand and thus follow the reference. The first thing to do is to ask questions like the ones we have just asked and to read t...

What do women really want?

What men want is thought to be understood quite well. In general, their sexual desire is orderly, consistent, and narrowly directed. A heterosexual man is heterosexual. If you show him heterosexual sex, his sexual physiology and subjective, reported desire rise in tandem. Homosexual sex will leave him cold both physically and emotionally. For men, there is an excellent match between physiological arousal (as measured by penile tumescence) and level of reported desire. Viagra’s success demonstrates the simplicity of the male mechanism. Viagra does not target desire, but works by increasing genital blood flow, allowing erection. This, apparently, is all that is needed in many cases. As the penis rises, desire is already waiting. For women, the story is different. The female body, studies show , likes everything, or at least responds to everything (or does not know what it likes, some cynics will say). Female physiological arousal (as measured by vaginal lu...
