Parasynthesis in Degema: Simultaneous affixation or suffixation and concomitant prefixation
(Linguistics Association of SADC Universities, 2015-04)This paper discusses parasynthesis, also known as circumfixation, in Degema. It highlights the fact that circumfixes are controversial not only because of the possibility to analyze them as discontinuous units consisting ... -
A tag-like, linked navigation approach for retrieval and discovery of desktop documents
(Springer, www.springer.com, 2011)Computer systems provide users with abilities to create, organize, store and access information. Most of this information is in the form of documents in files organized in the hierarchical folder structures provided by ... -
Strategies for naming tourist sites in Botswana
(University of Botswana http://www.ub.bw, 2014)This paper aims at establishing and discussing the strategies for naming tourist sites in the languages of Botswana using a descriptive approach. In addition, the paper attempts a classification of these tourist sites in ... -
Contending claims over access to fisheries: a case study of the Okavango Delta Panhandle, Botswana
(Canadian Center of Science and Education, http://www.ccsenet.org, 2013-02-26)Fishing is one of the key livelihood activities in the Okavango Delta in Botswana. Subsistence fishers, commercial fishers and tourist lodge operators derive material and non-material benefits from fishery. However open ... -
Disaggregating hydroperiod: components of the seasonal flood pulse as drivers of plant species disribution in floodplains of a tropical wetland
(Springer Link, http://link.springer.com/article/10.1007/s13157-014-0554-x#, 2014-06-22)Wetland hydroperiod consists of different components, including frequency, duration and depth. A significant proportion of the seasonally flood-pulsed Okavango Delta is inundated for part of each year. Variation in ... -
Determination of potentially toxic heavy metals in traditionally used medicinal plants for HIV/AIDS opportunistic infections in Ngamiland District in Northern Botswana
(Elsevier, www.elsevier.com/locate/aca, 2011-12-08)The determination of four potentially toxic heavy metals, arsenic, chromium, lead and nickel in twelve plant species used for the treatment of perceived HIV and AIDS-associated opportunistic infections by traditional ... -
Fish, floods, and ecosystem engineers: aquatic conservation in the Okavango Delta, Botswana
(American Institute of Biological Sciences, www.aibs.org, 2009-01)The Okavango Delta, Botswana, is a major wetland surrounded by the Kalahari Desert. The delta supports a diverse fish fauna that depends on highly seasonal flooding from inflowing rivers, and on the actions of ecosystem ... -
On non-metric covering lemmas and extended Lebesgue-differentiation theorem
(Science Domain International;http://www.sciencedomain.org, 2015-03-28)We give a non-metric version of the Besicovitch Covering Lemma and an extension of the Lebesgue-Differentiation Theorem into the setting of the integration theory of vector valued functions. -
On summable bases in Banach spaces
(Science Domian International, www.sciencedomain.org, 2014-06-24)We introduce the notion of summable bases that naturally generalizes the notion of unconditional sequence bases for Banach spaces. We shall be particularly interested in some classical results on sequences and series in ... -
A new general approach to vector valued stochastic integration
(International Journal of Modeling and Optimization, www.ijmo.org, 2014-08)We use an extended theory of integral that generalizes the integration of vector valued functions with respect to non-negative, monotonic,countably subadditive set functions, in order to introduce a new approach to stochastic ... -
A Leopard's Kopye burial at Mathangwane in northeastern Botswana
(South African Archaeological Society, http://www.archaeologysa.co.za, 2013)We report on a rare northern Leopard's Kopje grave in Botswana of a male from a small settlement, who, nonetheless, was buried with nine pots and many trade beads. The set of whole and decorated pots with traces of the ... -
On the Orlicz-Pettis theorem for integrals
(Pushpa Publishing House, www.pphmj.com, 2010-10)In this note, we propose a more efficient approach to the definition of the integral of Banach-valued functions that enables us to give an improved version of the Orlicz-Pettis theorem for integrals. -
Soils, science and the politics of knowledge: how African smallholder farmers are framed and situated in the global debates on integrated soil fertility management
(Elsevier, http://www.elsevier.com/, 2013)The paper addresses an important and often overlooked cultural aspect of smallholder agriculture in sub-Saharan Africa (SSA). This relates to how different policy organisations conceptualise soil management problem, its ... -
A flood pulse driven fish population model for the Okavango Delta, Botswana
(Elservier, www.elsevier.com/, 2012-03-10)The Okavango Delta is a large, remote, and ecologically significant wetland located in Botswana that receives a strong annual flood pulse. Although the hydrology in flood pulsed systems is often theorized to drive fish ... -
Pressurized hot water extraction coupled to molecularly imprinted polymers for simultaneous extraction and clean-up of pesticides residues in edible and medicinal plants of the Okavango Delta, Botswana
(De Gruyter, http://www.degruyter.com/, 2013-10-08)In this study, an in-cell extraction and clean-up approach, employing pressurized hot water extraction (PHWE) coupled to a molecularly imprinted polymer (MIP) is proposed. The selectivity of PHWE was improved through the ... -
