An investigation of the utility scale wind energy for north‐eastern Kenya region

In the present study, the wind energy potential for Garissa (0°28S, 39°38'E) and Marsabit (2° 19N, 37° 58'E), both rural towns in  north-eastern Kenya have been statistically analyzed on a 6-year  measured hourly time series wind speed data. The probability distribution parameters are derived the time series data and the distributional  parameters are identified and fitted annually on the basis of Weibull model. Garissas average wind speeds were found to range between 2.5 and 3.5 m/s giving power densities of between 74 and 190 W/m2 at a height of 50 m. The yearly value of Weibulls shape parameter k ranged from 1.26 to 1.38, whilst the values of the scale parameter c ranged between 2.92 and 3.90 m/s. In the case of Marsabit average wind speeds greater than 11 m/s are prevalent. The available power density at a height of 50 m is between 1776 and 2202 W/m2 which is in the wind class range of 7 and 8. Values of Weibull parameters k and c ranged between 2.5-3.05 and 11.86-12.97 m/s, respectively. From the analysis, the Marsabit site was found suitable for grid connected power generation while the Garissa site was found suitable for non]grid uses such as water pumping and battery charging.Key words: Wind speed, power law, Weibull parameters, wind class, wind rose, energy potentia

Genome Sequence of the Tsetse Fly (Glossina morsitans): Vector of African Trypanosomiasis

Tsetse flies are the sole vectors of human African trypanosomiasis throughout sub-Saharan Africa. Both sexes of adult tsetse feed exclusively on blood and contribute to disease transmission. Notable differences between tsetse and other disease vectors include obligate microbial symbioses, viviparous reproduction, and lactation. Here, we describe the sequence and annotation of the 366-megabase Glossina morsitans morsitans genome. Analysis of the genome and the 12,308 predicted protein–encoding genes led to multiple discoveries, including chromosomal integrations of bacterial (Wolbachia) genome sequences, a family of lactation-specific proteins, reduced complement of host pathogen recognition proteins, and reduced olfaction/chemosensory associated genes. These genome data provide a foundation for research into trypanosomiasis prevention and yield important insights with broad implications for multiple aspects of tsetse biology
