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, ... -
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 [1], and prove some useful characterizations that provide a foundation for studying relevant properties to the integration theory. As applications, we ... -
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 ... -
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 ... -
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. -
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 ... -
The Levi-Civitá equation, vector modules and spectral synthesis
(Banach Center Polish Academy of Sciences, 2013)The purpose of this paper is to give a survey on some recent results concerning spectral analysis and spectral synthesis in the framework of vector modules and in close connection with the Levi-Civita functional equation. ... -
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 ... -
More on equivalence properties of Radon-Nikodym property types and Complete Continuity property types
(Pushpa Publishing House, www.pphmj.com, 2013-01)We study the equivalence property of the I- and II-L-Radon-Nikodým property (resp. I- and II-L-complete continuity property) types of Banach spaces. As a by-product, we obtain a proof of the following: F. Lust-Picard’s ... -

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 ... -
Tensor Integral: A new comprehensive approach to the integration theory
(SCIENCEDOMAIN International, www.sciencedomain.org, 2014-09-15)We use tensor product to introduce a new approach to the theory of integration. Such an approach will strengthen the existing various classical concepts of integral and will provide a continuous thread tying the subject ... -
Observations on the effect of proximity to rhyolitic intrusions on Kübler index
(Mineralogical Society of Poland, http://www.degruyter.com/view/j/mipo, 2010)The Upper Ordovician sedimentary succession of southeast Ireland is riddled with almost synsedimentary igneous intrusions. A study was required to determine any effects of these intrusions on Kübler Index (KI) so that ... -
Microbial quality assessment and predominant microorganism of biltong produced in butcheries in Gaborone, Botswana
(Scientific Research Publishing Inc. http://www.scirp.org/journal/fns/, 2014)Biltong is a dried ready to eat meat product that is produced and consumed to a large extent in Botswana. A study was undertaken with the objective of determining the microbial quality and isolating and identifying the ... -
Neutral polyfluoroalkyl substances in the global Atmosphere
(The Royal Society of Chemistry, http://pubs.rsc.org/en/journals/journalissues/em#!recentarticles&all, 2014)Concentrations of neutral per- and polyfluoroalkyl substances (nPFAS) in the atmosphere are of interest because nPFAS are highly mobile percursors for perfluoroalkyl acids. Two calibration studies in Ontario, Canada and ... -
A sensitive LC-MS/MS method employing a THF/water solvent system for the determination of chloramphenicol, thiamphenicol and florfenicol in bovine muscle
(Royal Society of Chemistry ,www.rsc.org/, 2014)A THF–water solvent system was used in the development of a method for the LC-MS/MS determination of chloramphenicol (CAP), thiamphenicol (TAP) and florfenicol (FFC) in bovine muscle. The tetrahydrofuran (THF)–water solvent ... -
On the differentiability of vector valued additive set functions
(Scientific Research, http://www.scirp.org, 2013-11)The Lebesgue-Nikodým Theorem states that for a Lebesgue measure λ:Σ〖⊂2〗^Ω→[0,∞) an additive set function F:Σ→R which is λ-absolutely continuous is the integral of a Lebegsue integrable a measurable function ...
