Sorption of heavy metals by Ferralic-Arenosol and Vertic-Luvisol: a comparative isothermal study
(Canadian Center of Science and Education, http://www.ccsenet.org, 2014-02-26)
Modeling of sorption data is essential for characterizing retention of heavy metals by the soil matrices as well as to predict the fate of heavy metals in the environment. We carried out a study to evaluate adsorption ...
Unified approach to vector valued integration
(Pushpa Publishing House, www.pphmj.com, 2013-06)
We introduce a natural and more flexible approach to the definition of vector valued integral that will completely forgo any measurability assumption, strengthen the existing various classical concepts of ...
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.
Exponential polynomials on commutative hypergroups
(Springer, www.springer.com, 2013)
Polynomials and exponential polynomials play a fundamental role in the theory of spectral analysis and spectral synthesis on commutative groups. Recently several new results have been published in this field. Spectral ...
Assessment of diversity in Harpagophytum with RAPD and ISSR markers provides evidence of introgression
(Mendelian Society of Lund, http://www.hereditasjournal.com/, 2014)
The genus Harpagophytum has two species: H. procumbens which is an important medicinal plant in southern Africa, and H. zeyheri. Genetic diversity in 96 samples, obtained by germinating seeds collected from Botswana, was ...
On natural characterizations of tensor integrability
(Science Domain International, http://www.sciencedomain.org/, 2015-05-04)
We revisit the deﬁnition of the tensor integrability introduced in , and prove some useful characterizations that provide a foundation for studying relevant properties to the integration theory. As applications, we ...
tat Exon 1 exhibits functional diversity during HIV-1 subtype C primary infection
(American Society for Microbiology, http://jvi.asm.org/, 2013)
Human immunodeficiency virus type 1 (HIV-1) Tat is a mediator of viral transcription and is involved in the control of virus replication. However, associations between HIV-1 Tat diversity and functional effects during ...
The genetic prehistory of southern Africa
(Macmillan Publishers Limited, http://www.nature.com/ncomms/index.html, 2012)
Southern and eastern African populations that speak non-Bantu languages with click consonants are known to harbour some of the most ancient genetic lineages in humans, but their relationships are poorly understood. Here, ...
Effect of different grain spawns and substrate sterilization methods on yield of oyster mushroom in Botswana
(Int.J.Bioassays, http://www.ijbio.com, 2013)
The effect of three different grain spawns and two substrate sterilization methods on the spawn quality and yield of a hybrid of Pleurotus ostreatus x P. florida (Po x Pf) was studied on maize cobs supplemented with 20% ...
Refining the Y chromosome phylogeny with southern African sequences
(Springer, http://link.springer.com/journal/439, 2016)
The recent availability of large-scale sequence data for the human Y chromosome has revolutionized analyses of and insights gained from this non-recombining, paternally inherited chromosome. However, the studies to date ...
