Coastal climate and beach dynamics at Ponta do Ouro, Mozambique
Annual field surveys conducted at Ponta do Ouro in Southern Mozambique have determined that coastal variability is driven by high wave energy and consequent northward longshore drift. There is a log-spiral headland-bay system marked by 80 m tall forested dunes in the south that give way to a broad flat sandy beach. Marine climate processes that affect coastal erosion and accretion are studied using local and remote data...

An efficient hybrid distributed document clustering algorithm
Recent advances in information technology have led to an increase in volumes of data thereby exceeding beyond petabytes. Clustering distributed document sets from a central location is difficult due to the massive demand of computational resources. So there is a need for distributed document clustering algorithms to cluster documents using distributed resources. The greatest challenge in this area of distributed...

Exploring the effectiveness of dialogue in improving health facility deliveries
Maternal mortality is a concern worldwide with higher disparities of 1 in 16 in developing compared to 1 in 2800 in developed countries. Kenya’s maternal mortality ratio has increased from 414 per 100,000 live births in 2003 to 488 per 100,000 live births in 2009. In 2010 the figure increased to 530 per 100,000 live births. The purpose of the study was to explore the effectiveness of dialogue in improving health...

The fatigue flexural behavior of fiber reinforced concrete: Effect of the parameters of coarse aggregates
The effect of the coarse aggregate type on the fatigue flexural behavior of concrete was investigated in this work. Three types of the coarse aggregates were selected from three different careers (CA1, CA2 and CA3). The mechanical parameters of these aggregates were determined (Los Anglos and Micro Deval). Prismatic specimens (70×70×280 mm) for each concrete mixture were made with aggregates of each source....
