A scientist operates through a series of steps that have been known to contribute to the solution of the problem at hand. These steps are called the scientific method. They are what distinguish science from any other quest of knowledge.

HIV and AIDS is acknowledged as a global health crisis, for health workers, policy makers, and ordinary citizens in Africa and parts of Asia. Managing and coping with the reality and burden of HIV and AIDS is a never ending struggle. It has become part of everyday conversation in homes, working places, and social gatherings; it has also crept into lectures class notes and hence propelled itself to the top of the social economic and political agendas.

When charges move relative to each other,they experience a new force in addition to the electrstatic one.This new force is the magnetic force and can be shown to be a consequence of special relativity.

Seed industry has played a vital role in the availability of high quality seed of improved crop varieties with attendant modern power equipment, improved fertilizers, and better methods of insect and weed control. These altogether have revolutionized farming 1.1 Evolution of seed The evolution of plants has resulted in increasing levels of complexity, from the earliest algal mats, through bryophytes, lycopods, ferns to the complex gymnosperms and angiosperms of today. While the groups which appeared earlier continue to thrive, especially in the environments in which they evolved, each new grade of organisation has eventually become more "successful" than its predecessors by most measures. 1. Evidence suggests that an algal scum formed on the land 1,200 million years ago 2. To thrive and to avoid extinction, plants have made mechanisms and evolved seed plant during 200 million years ago 3. The latest major group of plants to evolve was the grasses, 40 million years ago 4. The grasses, as well as many other groups, evolved new mechanisms of metabolism to survive the low CO2 and warm, dry conditions of the tropics over the last 10 million years.

Human behavior plays a key role in most of the disease condition in life. a) Socialization; is a life long process through which individuals in a society develop an awareness of social norms and values; achieve destine of self. b) Norms: Rules and expectations conduct which either prescribes a given type of behavior, or forbid it. c) Values: Culturally defined standards held by human individuals or groups about what are desirable, proper, beautiful, and good or bad that save as broad guidelines for social life. d) The individualistic interpretation of disease places emphasis on the individual as responsible for his or health status. Health compromising behavior by individual is the main factor in health.

This unit is an introductory course whose main aim is to broaden your understanding and perspective of oral literature through studying the oral literature of your community and that of other East African communities. I am aware that, by now, most of you are exposed to some oral literature both through formal education and also through contact with the material as is practiced and performed within your own communities. However, I am also aware that due to various influences, students are not able to fully appreciate the multidimensionality of the oral literature discipline and more so its significance in literary studies. This course is thus designed so that your understanding of the subject becomes broadened and that you are able to appreciate: (a), the place of oral literature within the wider literary studies and African literature in particular. Oral literature needs to be recognised as a unique form of literary expression, exhibiting imaginative and creative dimensions that enrich the study of African literature; (b) the place of oral literature within the rich heritage of the African Oral traditions; (c) the place of oral literature in the rediscovery of African cultural heritage eclipsed by unfavorable historical circumstances and (d) the place of oral literature within the Contemporary written African literary tradition

PowerPoint is a presentation software package. With PowerPoint, you can easily create slide shows. Trainers and other presenters use slide shows to illustrate their presentations. This lesson introduces you to the PowerPoint window. You use the window to interact with the software.

Annual crop definition Crops that take not more than one year to mature Classification of Crops There are two major methods of classifying crops plants Botanical classification which is based on the morphological similarity of plants parts Economic classification is based on their uses 1. Botanical classification The grass family The legume family 2. Agronomic/economic classification Cereal or Grain crops Legumes Oil crops Root and tuber crops Fiber crops Forage crops Vegetable crops Rubber crops/latex crops Beverage crops 3. Special-purpose Classification Cover crops Botanical, agricultural or special classification
