Abstract
Objective

To describe the relationship between number and distribution of valves.
Methods

Sixty-six popliteal vein specimens were used for the study after routine dissection at the Department of Human Anatomy, University of Nairobi. The extents of the popliteal vein were identified at the adductor hiatus and soleal arch, cut at these points and then longitudinally sliced open. The number and distribution of valves were then recorded. Data were presented using photomacrographs and tables.
Results

The median number of valves was 1 (mean 0.8; range 0–2), with the lower part of the popliteal vein as the most consistent valve position. Most striking was the valve absence noted in 27 (41%) of the veins.
Conclusion

These findings suggest that a significant proportion of popliteal veins do not have valves thus providing a credible structural link that may predispose the popliteal vein to deep venous thrombosis in the study population.

For hydrological, agricultural and other raindependent activities, the estimates of the average rainfall over a catchment are very important.' Most of the methods formulated for estimating the areal average rainfall make use use of raingauges has several disadvantages which are, sometimes, not easily controlled. Due to these drawbacks, recent attempts ha~e been made to utilize remote sensing techniques in the estimation of areal rainfall. Areal estimation of rainfall from METEOSAT satellite data is the main objective of this study. 10-day and monthly total cold-cloud durations (CCD) for the months of January and February, 1987 covering the area within Latitudes 34°E to 400E and Longitudes 50S to 90S of S'butQ.ernTanzania, digitized corresponding to the raingauge statiction network,for three different temperature thresholds was used. These records of • -!Meteosat
data were'compiled at University of Reading, U.K. Daily raingauge records from 147 stations located within the study area were used. These records were used in generating 10-day and monthly total rainfall records which were employed in the study as "ground truth" records. The rainfall records were obtained from the Directorate of Meteorology df Tanzania, Dar es Salaam. The study was divided into three sections. The first section deals with the relationship between the point CCDs and the surface recorded rainfall. Si!.ipl

Abstractmagnitudes_of_climate_variability_and_changes_over_the_arid_and_semi-arid_lands_of_kenya_between_1961_and_2013_period.pdfAmerican Journal of Climate Change

The magnitude and trend of temperature and rainfall extremes as indicators of climate variability and change were investigated in the Arid and Semi-Arid Lands (ASALs) of Kenya using in-situ measurements and gridded climate proxy datasets, and analysed using the Gaussian-Kernel analysis and the Mann-Kendall statistics. The results show that the maximum and minimum temperatures have been increasing, with warmer temperatures being experienced mostly at night time. The average change in the mean maximum and minimum seasonal surface air temperature for the region were 0.74˚C and 0.60˚C, respectively between the 1961-1990 and 1991-2013 periods. Decreasing but statistically insignificant trends in the seasonal rainfall were noted in the area, but with mixed patterns in variability. The March-April-May rainfall season indicated the highest decrease in the seasonal rainfall amounts. The southern parts of the region had a decreasing trend in rainfall that was greater
than that of the northern areas. The results of this study are expected to support sustainable pastoralism system prevalent with the local communities in the ASALs.

One hundred and sixty seven volunteer medical students were exposed to intradermal skin tests for schistosomiasis. 35(21%) were positive. On further screening using routine stool and urine examinations, only 11(6.6%) were found to have eggs of Schistosoma mansoni. We conclude that although a useful procedure, schistosomal skin test should not be used alone for the diagnosis of schistosoma infections but should be complimented with the routine stool and urine examinations.
