Groundwater is inherently susceptible to contamination from anthropogenic activities and remediation is very expensive and often impractical. Prevention of contamination is hence critical in effective groundwater management. In this paper, an attempt has been made to assess the aquifer’s vulnerability to petroleum hydrocarbons contamination in Dar es Salaam City, Tanzania. Potential benefit from mapping vulnerability is that it aids in the prioritisation of monitoring boreholes located in...

The purpose was to explore teachers’ readiness to integrate computers in teaching mathematics and science in their classrooms. Participants were 58 teachers, 37 (63.8%) females and 21 males (36.2%) from 35 schools in the Gauteng province of South Africa. Data were collected through a questionnaire that required teachers to indicate whether they utilized computers during teaching and learning activities; the extent of their confidence levels in respect of different activities related to...

Water pollution is a chronic crisis in Sudan that is rarely researched. However, it is combined with scarcity, disputes and uncertainty. In The current paper we introduce its concepts with emphasis on the growing problems of pollution combined with scarcity. A Case study of the growing problem of pollution is introduced and analyzed using economic parameters.

Mutations in GJB2, a gene encoding the gap junction protein connexin 26 (Cx26), are a major cause for inherited and sporadic non-syndromic hearing loss, albeit with highly variable clinical effects. To determine new mutations and their frequencies in a Southern Egyptian population restriction fragment length polymorphism, gene sequencing, and single strand conformational polymorphism revealed only 2 mutations for GJB2: c.35delG and p.I71N. The allelic frequency of the c.35delG mutation was...
