Joint epicenter determination of earthquakes that occurred in northern Algeria near Ech Cheliff (named Orleansville in 1954 and El Asnam in 1980) shows that the earthquake of 9 September 1954 ( M = 6.5) occurred at nearly the same location as the earthquake of 10 October 1980 ( M = 7.3). The 1954 main shock and earliest aftershocks were concentrated close to the boundaries of segment B (nomenclature of Deschamps et al. , 1982; King and Yielding, 1984) of the 1980 fault system, which was to...

The shoreline positions were determined from ground surveys, maps, and aerial and satellite photos. Generally, the analysis reveals two remarkable shoreline migration trends: prograding shorelines during the 19th century, and a more recent retrograding shoreline trend during the 20th century. A...

The skills differential between manpower supply and demand is due to deeply rooted socio- and politico-educational misconceptions that can be remedied only by a concerted cooperative effort on the part of the general public, the State, organized industry, organized engineering, and engineering education. This will require the general public to recognize that the reasons for the shortages in engineering manpower should be regarded as critical. Public perceptions of engineering, of the...

Modified Ziehl Neelson staining technique was used to identify Cryptosporidium species oocysts in stool specimens. Faecal samples from 166 children with diarrhoea and from a control of 95 children, were submitted for examination. 13 children from among those with diarrhoea and none from the control group were found to have Cryptosporidium species oocysts. The majority of these 13 positive children presented with abdominal pain, nausea, low grade fever and anorexia.

Peak expiratory flow rate and anthropometric measurements were made on 248 healthy secondary school children in Northern Nigeria. The male children have significantly higher values (P less than 0.01) of peak expiratory flow rate in comparison to female children. The peak flow rate measurements both in male and female children show positive correlation with height and weight and body surface area. It was observed that results obtained in the present study were significantly (P less than...

Marked association with moniliasis and trichomoniasis was found. Gonorrhea was detected in two patients, but there was...

During a study of diabetes prevalence in six rural Tanzanian communities, a repeat oral glucose tolerance test (OGTT) was carried out in 514 subjects greater than or equal to 15 yr of age within 1 wk of an initial 75-g OGTT. In 498 subjects, blood glucose was measured 2 h after the glucose load on both occasions, and in 175 subjects, fasting blood glucose measurement was also repeated. Of the 498 subjects, 245 had normal glucose tolerance in the first test and were selected at random for...

Peoples' programme A very significant feature of the small-scale irrigation programme is that with a bit of ingenuity and tact it can be made a 'peoples' programme', and the community's active participation can be secured in its implementation. This will not only cut the costs of such schemes substantially, but will also encourage the people to think of these schemes as their own, which is very important to the success of any programme undertaken in the public sector. Obviously such a...
