Conflict among herders in East Africa is a common occurrence. It affects millions of people in many ways by extinguishing their livelihoods and forcing many others to change. This paper is focused on the East Pokot pastoralists’ adjustment to conflict. The paper first presents the East Pokot as a people, their history, brief interaction with the central government, and their geographical region...

Bridges and tunnels are semantically meaningful objects in Geographical Information Systems (GIS), playing an important role in terms of reachability between locations. From a topological point of view, bridges and tunnels on surfaces are captured by the notion of a handle. In this paper, we extend an existing axiomatic characterization of 3D surfaces, which guarantees consistency between geome...

Many research workers, to save time, rely entirely on either on-line or off-line databases offered by an increasing number of information services. The characteristics of eight databases, including five on-line services, were analysed in the present study concerning the retrieval of information on dengue, the most important mosquito-borne viral disease of humans. Differences in the rate of retr...

Recent technological advances have made it possible to process and store large amounts of image data. The most impressive example is the accumulation of image data in scientific applications such as satellite imagery. However, in order to realize their full potential, tools for efficient extraction of information and for intelligent search in image data bases need to be developed. The paper des...

We work in complex industrial system simulation on geographical, decisional and informational distribution terms. We postulate that existing methodologies and simulation tools seldom take account of these three distribution aspects. Our goal is to conceive a modeling and simulation solution that is able to utilize these aspects to resolve problems. This paper is divided into 4 parts. The first ...

Human immunodeficiency virus (HIV) is the worldwide disseminated causative agent of acquired immunodeficiency syndrome (AIDS). HIV is a member of the Lentivirus genus of Retroviridae family and is grouped in two types named HIV-1 and HIV-2. These viruses have a notable ability to mutate and adapt to the new conditions of human environment. A large incidence of errors at the transcriptional leve...

The composition of may vary due to plant sources its botanical geographical origin. has been used since ancient times in traditional medicine for therapeutic effects wound healing hepatoprotective. reported...

Before surveying the results of the paper, we introduce path algebras. Path algebras play a central role in the representation theory of finite-dimensional algebras (Gabriel, 1980; Auslander et al., 1995; Bardzell, 1997) and the theory of Gröbner bases (Bergman, 1978; Mora, 1986; Farkas et al., 1993) has been an important tool in some results (Feustel et al., 1993; Green and Huang, 1995; Bardze...
