We use K∗ n to denote the bidirected complete graph on n vertices. A nomadic Hamiltonian decomposition of K∗ n is a Hamiltonian decomposition, with the additional property that “nomads” walk along the Hamiltonian cycles (moving one vertex per time step) without colliding. A nomadic near-Hamiltonian decomposition is defined similarly, except that the cycles in the decomposition have length n − 1...

MILK IS one of the main products in most pastoral systems in Africa, yet the contribution of dairying to pastoral economies is often overlooked. This study of the nomadic pastoral system in South Darfur shows that milk not only meets 25% of a pastoral family's caloric requirements, but also has an important exchange value. Bartering dairy produce enables pastoralists to grow less crops and conc...

Nomadic computing using powerful portable systems has entered the mainstream of computing due to the recent progress in terms of performance and usability of the necessary hardware. However, most of these systems are still being used stand-alone with almost no provision for management support in the home as well as in the visited domain. This complicates connguration by forcing manual intervent...

Nomadic pastoralists of the African Sahel, the high steppes of central Asia (including the Tibetan Plateau and Mongolia), parts of the Near and Middle East, the Arabian Peninsula and India use mobility to manage uncertainty and risk in arid and semiarid ecosystems (Scoones 1994). In these areas, livelihoods are threatened by drought, diseases, insects and war, among other calamities. Semiarid p...

The paper builds on the work of Rossito et al. (2014) on collaborative nomadic work to develop three categories of practice of nomadic collaborative learning groups. Our study is based on interviews, workshops and observations of two undergraduate student’s group practices engaged in self-organised, long-term collaborations within the frame of Problem and Project Based Learning. By analysing th...

Sudan has high maternal mortality. The rate among nomads groups of people who move from place to place as a way of obtaining food, finding pasture or make a living is very high and varies between different regions of the country. The objective of the study is to identify the factors affecting the utilization of maternal health care services by nomadic communities in Sudan, to make recommendatio...

The frequently reported observation that nomadic populations have lower fertility than their settled counterparts is often attributed to what are perceived as harsh, stressful conditions under which the nomads live. But the consequences of the hypothesized stresses for the reproductive biology or demography of these populations have been documented only a little. Traditionally, the Turkana of n...
