This study is a part of a global approach in which, the main purpose is to understand the reasons behind the upsurge of flood events in the peri-urban area of the city of Dakar.pan> Hydrological and hydraulics simulations were carried out to assess the risks of overflowing of the Lake Warouwaye after a so-called exceptional rain. Data were collected through field surveys, as well as site observations of dwellings before and after rain episodes. The simulations were performed using EPA’s Storm Water Management Model (SWMM) software with input data obtained from sub-software and supervisory applications such as Google Earth, Excel, and Global Mapper. The simulation results show factors of natural and anthropogenic origin may contribute to dysfunction hydrological elements such as the watershed capacity to drain and store water. In light of the results of this study, institutional governance efforts are to be made and to be sustained in order to reverse the tendency to occupy rainwater natural flow channels. It will also be necessary to involve the first actors who are the potential victims of flooding caused by the recurrent overflow of reservoirs.

In dialysis treatment, the radio-cephalic arteriovenous fistula (RCAVF) is a commonly used fistula, yet its low maturation rate remains a challenge. To enhance surgical outcomes, the relationship between stenosis-prone locations and RCAVF anastomosis angle is studied during maturation by developing two sets of RCAVF models for early (non-mature) and mature RCAVFs at five anastomosis angles. The impact of hemodynamics and wall shear stress (WSS) is examined to determine optimal anastomotic angles. Results indicate that acute angles produce more physiological WSS distributions and fewer disturbed regions, with early stenosis-prone regions located near the anastomosis that shift to the bending venous segment during remodeling. A pilot study comparing clinical and numerical results is conducted for validation.

Dear Editor,In multicellular eukaryotes,Polycomb repression heritably si-lences gene expression programs not needed or detrimental for a given developmental stage or tissue(Schuettengruber et al.,2017).During cell fate reprogramming,Polycomb silencing can be overcome by the combined activity of multiple Trithorax group(TrxG)proteins(Wu et al.,2012;Liang et al.,2015;Schuettengruber et al.,2017).TrxG proteins are genetically defined as suppressors of homeotic defects caused by loss of Polycomb function and have diverse enzymatic activities(Schuettengruber et al.,2017).We used a genetic enhancer screen to identify candidate TrxG proteins and uncovered TrxG activity for components of the SWR1 chromatin remodeling complex,which deposits the histone variant H2A.Z(Deal et al.,2007;March-Diaz et al.,2008).

The nature of the MnCl2 salt as a filler to polycarbonate , including their composition, particles dimensions and homogeneity of distribution have been studied using different spectroscopic techniques (XRD, DSC and TGA). A slight increases in the chain-chain separation due to the interaction of the MnCl2 salt with the polycarbonate chains was observed , while a decrease in the optical energy gap (Eopt ) of the polycarbonate polymer with increasing the salt concentration was detected .However employing impedance spectroscopy in the frequency range 10Hz up to 106 Hz. reveals an increase in the dielectric permittivity and conductivity with increasing salt

pan style="font-family:Verdana;">The main reason for the early failure of radio-cephalic arteriovenous fistula (RCAVF) is non-maturity, which means that the blood flow rate in the fistula cannot increase to the expected value for dialysis. From a mechanical perspective, the vascular resistance at the artificially designed anastomosis causes an energy loss that affects blood flow rate growth and leads to early failure. This research studied how to maximize the RCAVF maturity and primary patency by controlling the energy loss rate. We theoretically analyzed and derived a model that evaluates the energy loss rate Eavf in RCAVF as a function of its blood vessel geometric parameters (GPs) for given flow rates. There was an aggregate of five controllable GPs in RCAVF: radial artery diameter (Dra), cephalic vein diameter (Dcv), blood vessel distance between artery and vein (h), anastomotic diameter (Da), and anastomotic angle (θ). Through this analysis, it was found that Eavf was inversely proportional to Dra, Dcv, Da, and θ, whereas proportional to h. Therefore, we recommended surgeons choose the vessels with large diameters, close distance, and increase the diameter and angle of the anastomosis to decrease the early failure of RCAVF. Simultaneously, we could explain the results of many clinical empiricisms with our formula. We found that increasing Dcv and θ was more significant in reducing Eavf than increasing Dra and Da. Based on our model, we could define two critical energy loss rates (Cela, Celb) to help surgeons evaluate
