S.rodhaini (Brumpt 1931) is a parasite of East African rodents which may possibly hybridize with the human schistosome S. mansoni. The adult male at maturity measures approximately 3mm long and possesses both oral and ventral suckers and a marked gynaecophoric canal. The oral sucker is surrounded by a ring of sensory receptors with a large number of inwardly-pointing spines set into deep sockets occupying the bulk of the ventral surface of the sucker. Numbers of scattered sensory receptors are found on both dorsal and ventral surfaces of the head (Fig. 1) together with two conspicuous rows of receptors situated symmetrically on each side of the midline. One row extends along the dorsal surface of the head midway between the dorsal midline and the lateral margin.

Telepractice technology allows greater access to speech-language pathology services around the world. These technologies extend beyond evaluation and treatment and are shown to be used effectively in clinical supervision including graduate students and clinical fellows. In fact, a clinical fellow from the United States completed the entire supervised clinical fellowship (CF) year internationally at a rural East African hospital, meeting all requirements for state and national certification by employing telesupervision technology. Thus, telesupervision has the potential to be successfully implemented to address a range of needs including supervisory shortages, health disparities worldwide, and access to services in rural areas where speech-language pathology services are not readily available. The telesupervision experience, potential advantages, implications, and possible limitations are discussed. A brief guide for clinical fellows pursuing telesupervision is also provided.

Natural Language Processing for under-resourced languages is now a mainstream research area. However, there are limited studies on Natural Language Processing applications for many indigenous East African languages. As a contribution to covering the current gap of knowledge, this paper focuses on evaluating the application of well-established machine translation methods for one heavily under-resourced indigenous East African language called Lumasaaba. Specifically, we review the most common machine translation methods in the context of Lumasaaba including both rule-based and data-driven methods. Then we apply a state of the art data-driven machine translation method to learn models for automating translation between Lumasaaba and English using a very limited data set of parallel sentences. Automatic evaluation results show that a transformer-based Neural Machine Translation model architecture leads to consistently better BLEU scores than the recurrent neural network-based models. Moreover, the automatically generated translations can be comprehended to a reasonable extent and are usually associated with the source language input.

The article analyses the role of renewable energy in the process of the development of the energy market of the East African Community (EAC) . The author underlines the necessity of finding solutions for such challenges as rising wood and charcoal prices, deforestation, lack of affordable and reliable electricity for a large number of consumers. The study reveals that nowadays the percentage of people with access to modern sources of energy is very low, varying from 7 % in Burundi to 36% in Kenya, although the EAC countries made significant progress in 2000s. Most people in rural areas rely on traditional biomass for cooking and heating, which leads to ecological and health problems. The author concludes that renewable energy development is considered by the Community as one of the prospective ways for providing energy to remote regions in view of abundant solar, wind and geothermal resources. Their strategy aims at the construction of micro and mini hydro stations, stand-alone solar PV systems and off-grids for rural population usage. The study shows that the investment in off-grid renewables has been steadily rising in recent times . Analyzing grid-connected power generation electricity, the author elicits that it is also based on renewable electricity, which accounts for 65% of the total amount. Kenya, with the highest installed capacity in this sector, is investing mainly in geothermal, solar and wind sources of energy, while the others are focusing on hydropower and solar. For the purpose of attracting private investment, the EAC partner states adopted different regulations, including Feed-in Tariff, zero-VAT and GET FIT Programme. The author assumes that renewable energy financing is one of the main challenges despite the support of different international financial institutions, such as the World Bank, UNIDO, AfDB and others. Nowadays energy efficiency measures are becoming important instruments for the EAC countries resulted in power savings. The other important trend is increasing cooperation among them due to their grid-connected power systems in the East African Power Pool. In this context, in November 2017, the EAC Partner States adopted Energy Security Policy Framework, in order to ensure the sustainable development of their energy sector.
