Recent high-energy missions have allowed keeping watch over blazars in flaring states, which
provide deep insights into the engine powered by supermassive black holes. However, having
a blazar caught in a very bright ...
Bird species richness and densities in relation to sulphur dioxide gradients and environmental variables
(Taylor & Francis, 2017)
The expansion of coal-fired power stations in South Africa has resulted in growing environmental concerns as they are the largest emitters of sulphur dioxide (SO2). Sulphur dioxide emissions from power plants pose a potential ...
Automatic vs manual assessment of programming tasks
(ACM, 2017)
Lecturers are struggling to keep up with their daily responsibilities because of an ever-increasing workload. Manual programming assessment processes are time-consuming, but a possible solution is to use the assistance of ...
Targeting inflammation to reduce cardiovascular disease risk: a realistic clinical prospect?
(Wiley, 2017)
Data from basic science experiments is overwhelmingly supportive of the causal role of immune-inflammatory response(s) at the core of atherosclerosis, and therefore, the theoretical potential to manipulate the inflammatory ...
Rasch analysis of the Meaning in life Questionnaire among adults from South Africa, Australia, and New Zealand
(BioMed Central, 2016)
Background: Meaning in life is a key indicator of subjective well-being and quality of life. Further developments in

A new spider mite species Brevinychus meshacki Toroitich and Ueckermann n. sp., collected on Philonoptera eriocalyx Harms (Schrire) from Sangasanga in Mvomero district of Tanzania, is described and illustrated. This species ...
Plant functional types differ between the grassland and savanna biomes along an agro-ecosystem disturbance gradient in South Africa
(Elsevier, 2017)
Intensive, large-scale cultivation of food crops has led to major biodiversity loss worldwide due to fragmentation and degradation of remnant semi-natural habitat within agro-ecosystems. The response of vegetation to these ...
Aspects influencing the selection of representative urbanization measures to quantify urban-rural gradients
(Springer Science, 2011)
The quantification of urban–rural gradients using urbanization measures has become standard practice in many urban ecological studies. Nonetheless, the choice of urbanization measures for a specific urban gradient still ...
