Arthrogryposis multiplex congenita (AMC) is constellation of contractions of multiple joints present at birth with fat or fibrous tissue partially or totally replacing muscles. Aetiological cause is from the interplay of genetic and environmental factors. It affects approximately 1 in 2-3000 live births. All four extremities are involved in50-60% of cases; lower limbs, in 30-40%, and upper limbs, in 10-15% of cases. Our patient is case of Amyoplasia with duodenal atresia. Had surgery and was seen in the clinic on follow up to 3 months. He has remain stable on physiotherapy.

Studies on housing quality have focused on urban and rural areas with no consideration of coastal areas, especially on how residents perceive it. This paper, therefore, examines the importance coastal dwellers attached to housing quality and the level of satisfaction derived from the quality of housing. The results of the study showed that the expectations of the coastal dwellers in terms of their housing needs were not met. The study concluded that for coastal dwellers aspiration to meet with their satisfaction level, redevelopment and rehabilitation will have to set in order to boost and enhance the living condition of the coastal residents.

Adequate information of the raindrop size distribution is very significant for the prediction and evaluation of attenuation signal due to rain. In this study, an analytical approach is adopted to determine the peak diameter  where the specific rain attenuation is maxima in Durban (29º52'S, 30º58'E), South Africa; using the spherical raindrop shape at temperature T = 20ºC. The overall rainfall attenuation is computed by integrating over all the drop sizes and determine the differential change in the attenuation as observed over a fixed diameter interval, (= 0.1 mm). The critical diameters are the range of diameters where the rain attenuation is highly predominant, which constitutes the surface area under the curve and along the abscissa regions. The critical diameters are seen to coalesce around the peak diameter, at which the maximum attenuation occurs. The maximum specific rain attenuation peaks at the diameter It was observed that the peak diameter is frequency dependent while the parameters, µ, the mean and σ the standard deviation which determines the width of the distribution are found to be region-dependent. The peak attenuation for the stratiform rainfall type varies between 0.8 ≤ D ≤ 1.5 mm whereas for the convective rainfall, the specific rain attenuation peaks between 1.4 ≤ D ≤ 2.7 mm at all frequencies. A proper knowledge of the rainfall attenuation characteristics is useful for proper planning and for the purpose of link budget analysis by operators in this particular region.

The investigation reveals the stratigraphic sub-division of the site within the depth explored. Basically, though at some depths the lithology is similar, they are different sediments as revealed by the laboratory tests. Essentially, the site consists of silty clay on the surface that is soft in consistency and weak in shear strength. However, the consistency and the strength of the clay improve down depth from 14.50m where it becomes soft-firm. At 30.00 m depth, the clay becomes very firm as some shell fragments (mostly calcareous shells of gastropods and mollusks) occurred within it. Below this clay unit at about 45.00 m depth, a dense to very dense Sand unit of about 10.00m -12.00m thick occurs. The sand is poorly to moderately graded.  Below this sand unit at about 57.0m depth, another firm clay unit occurs. This clay unit becomes intercalated with sand at 60.50m and continues to about 62.50m where it grades into firm clay and continues to the termination depth at 66.00m. Based on the findings, a number of recommendations have been formulated for the safe and cost effective development of this Oil Field.
