Stratégies pour le relèvement d’un secteur de la santé en crise. Cas de la crise contemporaine de la pandémie de Covid-19 au Rwanda

Pour que l’action sanitaire humanitaire soit cohérente et coordonnée, il est essentiel de convenir d’une stratégie d’intervention du secteur de la santé, notamment de définir des objectifs précis et des activités stratégiques (mondiale de la Santé, 2005). Les principaux acteurs du secteur de la santé doivent tous participer à la définition de ces éléments, qui …

A Waste Heat Recovery Steam Power Generation System. A Case Study of Jabana II Power Plant Station in Rwanda

Abstract The increasingly worldwide problem regarding rapid economy development and a relative shortage of energy, the internal combustion engine exhaust waste heat and environmental pollution has been more emphasized heavily recently. Out of the total heat supplied to the engine in the form of fuel, approximately, 30 to 40% is converted into useful mechanical work; the remaining heat is expelled to the environment through exhaust gases and engine cooling systems, resulting into entropy rise and serious environmental pollution, so it is …

Feasibility study of utilization of harvested rainwater at Integrated Polytechnic Regional College of Karongi, Rwanda

In Rwanda, after 1994 Genocide tremendous efforts have been made in order to improve the water and sanitation sector. In these days, Rwanda government has made efforts in improving available quantity of water in use. Rainwater harvesting is one among of the solution of water scarcity in the country. The objectives of this work is to estimate the water demand, the quantity of rainwater that can be harvested from Integrated Polytechnic Regional College of Karongi (IPRC Karongi) buildings, the design of storage tanks and the implementation possibilities of this project. The required water demand is estimated to 45 liters per capita per day. The data have been analyzed and the calculated quantity of rainwater is 12,296.15m3 per year and the storage capacity is1, 496.24m3. At the end of the work, the result shows that rainwater harvesting technique can save 22% of the bills paid for water every year. We note that the report deals with untreated water for non-consumptive activities. It is recommended to do further research concerning the treatment of rainwater for drinking purposes, so that the students may access the treated rainwater. I suggest implementing this project as soon as possible because of its many advantages.

Design of apartment to improve dwelling area in Rwanda

As the title shows, the purpose of this project is to improve dwelling area in apartment scale. Today high mass of residential zones and high price of land leads the employers and users to residential architecture. Apartment life creates an undeniable situation for human beings of which we can point out chances and threats for residents. Unfortunately compact structure of big cities and lack of land along with financial issues and growing needs of users to dwellings and also inconformity of dwelling structure with today’s life, and also high physical and social price leads to denial of the identity of dwelling. Also scales of apartment units is decreasing by sharp increase of condense and high price of land in center of big cities. This fact reveals the importance of exact structure for apartment in small scale. The purpose of this research is to reach at principles of designing optimized dwelling in large scale by taking into account factors such as society, family and individuals. This article by studying revenues needed in each section, along with using questionnaire and by conforming residents in small scale, gets closer to the proposed principle of optimizing apartment in small scale.3 main principles for optimizing apartment in small scale are: contracting, applicability, flexible furniture and glassines.

Design of rain water harvesting system in Rwanda

Rainwater harvesting (RWH) system is a technology that focuses on sustainability and support the sustainable environment development. The implementation of RWH systems provides many environment and financial benefits. Some of the environment benefits of RWH system are the reduction of surface runoff, reduce the burden of soil aquifer, and provide the availability of clean water. This study analyzed the RWH system implementation benefits both in environment and financial side. The financial benefits of RWH system implementation are calculated based on a number of rainwater that can be used to replace the need for clean water.The environment benefits defined by the reduced of main water tap use and the reduced of generated roof runoff volume. This study used a simple RWH system that use the roof as a catchment area, the pipeline as a distribution system, and tank as the storage system. The water use is for domestic potable and no potable for a household with up to four occupants in Bandung. The catchment area is taken 70 m2. A water balance model for various scenarios was developed to calculate the algorithm of the system. The costs taken in RWH system includes the construction, installation, maintenance and operational costs. The analysis shows that the implementation of RWH systems provides advantages over the use of conventional systems. It can save clean water use up to 54,92% and provide runoff reduction up to 71,53%. RWH system applied requires additional costs approximately only 0,66% from the value of the house. It was found that it is possible to achieve payback in RWH system implementation under several scenarios.

Design and realization of basic block dress

The aim of this research is formulating the motif pattern of dress which can be extended into various sizes basic dress in which the motif is sanggit patterned. This employed action-participatory research to test the draft pattern by actively involved the batik entrepreneurs, motif designers and tailors. The data were collected through the techniques of observation, interviews, FGDs and document analysis. The result produces a pattern of brock pattern rectangular dress motif, 115 cm width and 250 cm length, divided into 12 symmetrical objects of vertical axis. The pattern works to develop the motifs, which can be made into a basic block batik dress of various sizes (S, M, L, XL and XXL). It is quite effective and efficient to develop random batik asymmetrical motifs and the resulting motif can meet sanggit at the front dress or zip, the left, right sides, sleeve and specific motifs on darts and neck line.
Keywords: patterns; motifs; basic dress; batik; sanggit.

Structural design of public swimming pool at University of Global Health Equity Butaro campus, Rwanda

Swimming pools have become an essential attachment to most habitable coastal construction such as hotels, condominiums and single family residences. A large swimming pool type structure may obstruct the free flow of flood water and increase the turbulence. This in turn may increase the scour potential and the wave/debris action on the building and foundation. A conceptual breakaway concrete swimming pool design is described herein. It is demonstrated that this pool will withstand everyday factored water/soil loading, but will collapse and break away under extreme wave action, thereby minimizing the detrimental effects of a solid pool. This study was done based on the serious issues of stress remarkable from various institution in Rwanda, especially those who are increasing their life standards in spending their money in hardworking. The main aim is to design public swimming pool appropriate to such organization and uniquely beneficial to the improvement of their health through leisure. It is designed to serve an institution of 200 members approximately within their special guests. The site was visited, and some data were collected. Soil parameters consist of internal friction angle, internal friction angle coefficient and the unit weight of the subsoil. The site visit permits really to select a shaped rectangular pool of public swimming pool. This study did not include bills of quantities which would be another way considered before when deciding the implementation. The results observed in this study is that a selected rectangular swimming pool can be stable for concrete of fcu=30N/m, on stem and key elements T20@300C/C bottom and T10@200C/C top can be used, at T20@280C/C and T10@220C/C bottom and top reinforcement respectively was found at heel, toe can use T12@300C/C and T10@220C/C and slab T10@200C/C and T10@300C/C bottom and top reinforcement respectively. At the end of the study different conclusion and recommendation was highlighted.
