The y-ray spectrum of the core of Centaurus A as observed with H.E.S.S. and Fermi-LAT
(EDP Sciences, 2018)Centaurus A (Cen A) is the nearest radio galaxy discovered as a very-high-energy (VHE; 100 GeV–100 TeV) γ-ray source by the High Energy Stereoscopic System (H.E.S.S.). It is a faint VHE γ-ray emitter, though its VHE flux ... -
Zooplankton and diatoms of temporary and permanent freshwater pans in the Mpumalanga Highveld region, South Africa
(Taylor & Francis, 2014)This paper provides a description of the zooplankton and epiphytic diatom communities of permanent and temporary freshwater pans in the Mpumalanga Highveld region of South Africa. Few studies have investigated the biota ... -
Zooplankton composition of temporary pools within the lower Nata River channel, Botswana, during dry season
(Taylor & Francis, 2020)The Nata River is a seasonal system situated in the semi-arid north-eastern Botswana, where rainfall is unpredictable and drought is common. The annual flow of approximately 279 million cubic meters is regionally significant ... -
α-Pyridinyl alcohols, α,α’-pyridine diols, α-bipyridinyl alcohols, and α,α’-bipyridine diols as structure motifs towards important organic molecules and transition metal complexes
(Bentham, 2020)Background: The preparation and use of pyridinyl alcohols as ligands showed incredible increment in the past three decades. Important property of pyridinyl alcoholato ligands is their strong basicity, which is mainly due ... -
The α2C-adrenoceptor antagonist, ORM-10921, has antipsychotic-like effects in social isolation reared rats and bolsters the response to haloperidol
(Elsevier, 2016)Early studies suggest that selective α2C-adrenoceptor (AR)-antagonism has anti-psychotic-like and pro-cognitive properties. However, this has not been demonstrated in an animal model of schizophrenia with a neurodevelopmental ... -
β-carotene and retinol contents in the meat of herbivorous ungulates with a special reference to their public health importance
(Japanese Society of Veterinary Science, 2016)The aim of this study was to estimate total carotenoids, β-carotene and retinol concentrations in the livers and muscles of some ungulates (cattle, buffalo, sheep, goats and horses) in comparison with the Wistar rats as a ...
