DISTRIBUTION AND DIVERSITY OF AQUATIC MACROINVERTEBRATE ASSEMBLAGES IN A SEMI-ARID REGION EARMARKED FOR SHALE GAS EXPLORATION (EASTERN CAPE KAROO, SOUTH AFRICA).

This study aims to C-500 investigate macroinvertebrate assemblage structure and composition across the three major waterbody types (temporary rivers, depression wetlands and semi-permanent dams) of the Eastern Cape Karoo, and to identify important environmental and spatial correlates of macroinvertebrate assemblage composition in the region.A total

Measuring the space area of obstacles is one of the important problems in obstacle localizing fields.Most of the existing research works on the localization of obstacles focus on where the obstacles are, and few of them measure both the positions and the areas of the obstacles.In this paper, we propose a Minimum convex bounding Polygon localizing a

The present paper deals with the evaluation of the impact of newly developed biofuels together with a comparison with conventionally produced fuel, diesel, in terms of their impact on the technical and emission condition of a studied vehicle.The main energy and emission parameters of the internal combustion diesel engine were evaluated.For laborato

This paper examines a curatorial approach to digital art that acknowledges the symbiotic relationship between the digital and other more traditional art practices.It considers some of the issues that arise when digital content is delivered within a public gallery and how specialist knowledge, audience expectations Jacket and funding impact on curre
