On the subspace problem for Quasi-normed spaces
(ScienceDomain International; www.sciencedomain.org, 2016-07-02)
A definitive positive answer to the so-called proper subspace problem (a.k.a. the atomic space problem) for quasi-normed spaces is given: every infinite dimensional quasi-normed space has a proper closed infinite-dimensional ...
Gravity and Aeromagnetic Studies of the Filabusi Greenstone Belt, Zimbabwe Craton: Regional and Geotectonic Implications
(Scientific Research Publishing Inc., http://www.scirp.org, 2012)
The Filabusi greenstone belt (FGB), Zimbabwe craton, has been geologically remapped relatively recently but its regional tectonic setting and subsurface structure have, until now, remained unresolved. This paper presents ...
Geoelectric Evaluation of Groundwater Potential and Vulnerability of Overburden Aquifers at Onibu-Eja Active Open Dumpsite, Osogbo, Southwestern Nigeria
(Scientific Research Publishing Inc., http://www.scirp.org/journal/JWARP/, 2016)
Electrical resistivity method was used to assess groundwater potential and vulnerability of overburden aquifers at Onibu‐Eja active open dumpsite, Osogbo, Southwestern Nigeria. Eighteen Vertical Electrical Sounding (VES) ...
Two new pterocarpans and a new pyrone derivative with cytotoxic activities from Ptycholobium contortum (N.E.Br.) Brummitt (Leguminosae): revised NMR assignment of mundulea lactone
(Springer International Publishing, http://link.springer.com, 2016)
Background: Ptycholobium is a genus related to Tephrosia which comprises only three species. Compared to Tephrosia, which has been phytochemically and pharmacologically studied, Ptycholobium species have only few or no ...
Absorption of Microwaves in Low Intensity Eucalyptus Litter Fire
(Scientific Research Publishing Inc., http://www.scirp.org, 2015)
A fuel bed was constructed where various vegetation species could be used as combustion fuel. The fuel bed was equipped with a thermocouple to measure fire temperature and a two-port automatic network analyser to measure ...
Extensions of the Lusin's Theorem, the Severini-Egorov's Theorem and the Riesz Subsequence Theorems
(ScienceDomain International; www.sciencedomain.org, 2016-10-14)
We give extensions of the Lusin’s Theorem, the Severini-Egorov’s Theorem, and the Riesz Subsequence Theorems to the setting of a non-additive vector valued set functions and sequences of functions taking values in general ...
Controlled Texturing of Aluminum Sheet for Solar Energy Applications
(Scientific Research Publishing Inc., http://www.scirp.org/, 2015)
Aluminum sheets were polished to reduce ruggedness and then textured in varying acid-ethanol concentration etchant to form pores. The textured surface was characterized structurally by using X-ray diffraction (XRD) which ...
Making markets work for the poor (M4P) approach and smallholder irrigation farming
(Omics Publishing Group; www.omicsgroup.org, 2015)
The aim of this article is to show what M4P is, how it came into being and how it has been used to guide
intervention in different context and to weigh the extent to which it can be used to guide the study and interventions ...
Seasonal diet preference of cattle, sheep and goats grazing on the communal grazing rangeland in the Central District of Botswana
(Academic Journals; http://www.academicjournals.org/AJAR, 2015-07-16)
Diet composition, forage preference and diet overlap among of goats, sheep and cattle grazing on communal rangeland in the Central District of Botswana were evaluated to determine the potential for forage competition to ...
Analysis of volatile compounds in Khadi (an unrecorded alcohol beverage) from Botswana by Gas Chromatography-Flame Ionization Detection (GC-FID)
(Sabinet;https://journals.co.za/, 2014)
Chemical analysis of volatile compounds from khadi, an unrecorded alcoholic beverage from Botswana, was carried out using gas chromatography-flame ionization detection (GC–FID). Ten samples of khadi from two different ...
