Unit groups of cube radical zero commutative completely primary finite rings
(Hindawi Publishing Corporation, 2005-07)A completely primary finite ring is a ring R with identity 1 = 0 whose subset of all its zero divisors forms the unique maximal ideal J. Let R be a commutative completely primary finite ring with the unique maximal ideal ... -
On Unit Groups of Completely Primary Finite Rings
(The Berkeley Electronic Press (bepress), 2008-01)Let R be a commutative completely primary finite ring with the unique maximal ideal J such that J3 = (0) and J2 6= (0): Then R⁄J ∼= GF(pr) and the characteristic of R is pk, where 1 ≤ k ≤ 3, for some prime p and positive ... -
On a Class of finite rings
(Taylor & Francis, 2007-06-27)In [7], Corbas determined all finite rings in which the product of any two zerodivisors is zero, and showed that they are of two types, one of characteristic p and the other of characteristic p2. The purpose of this paper ... -
Perceived Influencers of the Decline on Performance of Students in Botswana General Certificate of Secondary Education's Agriculture Examination Results.
(Canadian Center of Science and Education, 2016)The purpose of the study was to investigate factors perceived to contribute to the decline of students' performance in the Botswana's General Certificate of Secondary Education (BGCSE) agriculture results. Ninety-one ... -
Growth Performance of Guinea Fowl Fed Diets Containing Yellow Maize, Millet and White Sorghum as Energy Sources and Raised under Intensive System
(Asian Network for Scientific Information, 2013)This study investigated growth performance of guinea fowl fed diets containing 3 cereal grains as energy sources in comparison to commercial broiler diets. Birds were raised under intensive system from 3 to 16 weeks of ... -
Rangeland monitoring and assessment: a review
(University of Hamburg, 2018)Rangelands provide vast landscapes for grazing and foraging for livestock and wildlife. Services of rangelands are diverse and generally provide food for millions of the world’s population, especially the rural and sometimes ... -
Influence of Feed Type on Egg Production of Tswana Laying Chicken
(Ansinet, 2003)The experiment was done at estate management Unit in Sebele, Gaborone. Ten 23 weeks old laying Tswana chickens were bought from a local farmer and divided into two groups of five each, using complete randomized design. ... -
Azanza garckeana: A Valuable Edible Indigenous Fruit Tree of Botswana
(Asian Network for Scientific Information, 2004)Azanza garkeana (morojwa) is a valuable edible indigenous fruit tree species confined to east and southern Africa. Because of its multiple use the species is selected and retained by farmers in Botswana when they clear the ... -
Atriplex Nummularia (Old Man Saltbush) : A Potential Forage Crop for Arid Regions of Botswana
(Asian Network for Scientific Information, 2003)Atriplex nummularia (Old man saltbush) is widely planted on salt affected land to provide a vegetative cover, which can be used as fodder reserve. Such plantations are also perceived as having the capacity to use saline ... -
Lucerne, Lablab and Leucaena leucocephala Forages: Production and Utilization for Livestock Production
(Asian Network for Scientific Information, 2003)An overview is given of three legume pastures with potentials as sources of crude protein and other important nutrients for livestock production in Botswana. This paper reviews distribution, plant description, agronomic ... -
Potentials of Guinea Grass (Panicum maximum) as Forage Crop in Livestock Production
(Asian Network for Scientific Information, 2004)Panicum maximum (guinea grass) is native to Africa but this grass was introduced to almost all tropical countries as a source of animal forage. It grows well on a wide variety of well drained soils of good fertility and ... -
Feeding Values and Anti - Nutritive Factors of Forage Tree Legumes
(Asian Network for Scientific Information, 2003)Animal production in Botswana suffers from inadequate feed quantities and qualities, due mainly to semi-arid low rainfall which can barely support arable farming in most years. This problem is compounded by the competition ... -
