The new financial environment reveals new risks that make the uncertain profitability of banks and the occurrence of systemic risk resulting from the bankruptcy of several banks. Share the data provided by the National Bank of the DRC, the supervisor can detect banks of fragility signs by comparing the ratios calculated for each of them to set prudential standards and classifying them, taking into account the risks. So it can expedite inspections and take corrective actions that impose and help redress the situation if not close unprofitable banks. This is the mission that we assign to our study and propose to the Congolese supervisor of banks. The question that arises is what is the consistent methodology select and recommend to the Central Bank of Congo to enable supervision to achieve its objective to detect weak banks. The selected Promethee Visual (because we are in the storage problem) in our study, using 10 banks supervised by the Congolese central bank and accepted for clearing (like shares) and the 5 criteria (capital, assets, management, earnings and liquidity) shows First Bank Corporation (FBC = B10), CITIBANK (B10), trade and development bank (BCD = B8) are managing their banking risks. Banks to watch are the Congolese Union of Banks (UCB = B2), the international credit bank, the International Bank for Africa in Congo (BIAC = B3), the Commercial Bank of Congo (BCDB = B1). Finally, the Congolese foreign trade bank (BCCE = B9), the Congolese FSB (B7), and finally the STANBIC (B6) are high-risk banks. Our study shows that the supervisor Multi-method provides a consistent procedure in assessing the performance and risk of Congolese Banks.

The thermal transfer in the tow plaster (insulating material) is modeled by numerical method resolution in transient regime. The discretization of the reduced space variable and the reduced temporal variable is applied to the heat equations, the boundary conditions and the initial condition. The expressions of the dimensionless temperature allowed to represent the curves of evolution of the reduced temperature in the reduced time. The time constant characterizing the reduction of the reduced temperature in the material makes it possible to calculate its thermal diffusivity.

The study of heat transfer under dynamic transient conditions established the tow-plaster material thermal resistance. We present a one-dimensional heat transfer study using a Tow-plaster material. We show the thermal resistance evolution of in the material subjected to climatic solicitation in transient dynamic regime. This is a one-dimensional, fully analytical modeling. This model allows us, on the one hand, to express the thermal resistance in the form of a sum of three resistances and thus to show the tow-plaster material relative thermal resistance. This study is highlighting in relation to the thermal behavior of the material by showing the influence of the coefficients of exchange.

Kenya is classified as water scarce country yet the existing fresh water resources are under constant threat of pollution resulting from wastewater inflows. Wastewater contains nitrates and phosphates that stimulate excessive plant growth when released into water bodies thus deteriorating their quality. The purpose of the study was to evaluate the performance of Vetiver grass in the uptake of Nitrogen and Phosphorous from the three (horizontal, vertical and hybrid subsurface flow wetland systems) model constructed wetland units for treating municipal wastewater. Nitrogen and phosphorous accumulation in the roots and shoots of the Vetiver grass was determined and the data subjected to ANOVA at 5% confidence level. Vetiver grass accumulated 18,100 mg and 35.3 mg/kg Nitrogen and Phosphorous, respectively in the hybrid system compared to 9,400 mg Nitrogen and 19 mg/kg Phosphorous, in the horizontal subsurface flow system and 10,400 Nitrogen and 18.3mg/kg Phosphorous in the vertical subsurface flow system. Accumulation of nitrogen and phosphorous by Vetiver grass in all the wetland systems were significantly different (P≤0.05). There was also significant (P≤0.05) difference of N and P accumulation in the shoots and the roots with N accumulating more in the shoots while P in the roots.

This study is the fruit of the investigations (searches) which were done during two years (from 2015 to 2016) about the question of “How young people of Ibanda City (Freetown) in Bukavu plunge in practice and in the life of alcoholism. Practically, though the notice we would like to know this bad behavior of this category of people, who is, however the future hope, and suggest some ways (traks), in different domains, in order to save what can be saved on time.
