Introduction:The management of children with type 1 diabetes has been revolutionized first by the discovery of insulin and then by the development of new technologies. Nevertheless, the majority of patients still do not reach their glycemic target. The main objectiveof this study is to determine the predictive factors of good metabolic control in children with type I diabetes, in order to develop tailored approaches to improve the quality of management and prevent disease-related complications. Materials and Methods:Prospective analytical and descriptive study spread over 6 years from January 2015 to January 2021 including type 1 diabetic children diagnosed between 2015 and 2019 and followed up at the House Of The Young Diabeticin collaboration with the diabetes department of the childrens hospital (P2). Clinical and epidemiological data were obtained from patients medical records and the Free diab database. Results:The number of patients meeting the inclusion criteria was 542. A mean A1C in the target range was associated in bivariate analysis with patient age (p=0.003), parental socioeconomic and academic level (p=0.001), adhesion to health coverage (p=0.001), initial HbA1C value (p=0.001), number of self-monitoring of blood glucose (p=0.001), and treatment regimen (p=0.001). In multivariate analysis, the association was statistically significant for 5 parameters: socioeconomic level ( ß 0.10 95%CI 0.10-0.26 p 0.03), parents academic level (ß 0.15 95%CI 0.24-0. 5 p=0.002), adhesion to health coverage (ß 0.12 95%CI 0.18-0.46 p=0.001), initial A1C level (ß 0.16 95%CI 0.15-0.38 p Conlusion:Our study demonstrates parameters related to good glycemic control that need to be taken into account to develop new management strategies for children with type 1 diabetes.

The objective of the current research was to perform an experimental pilot study of municipal sewage wastewater treatment by activated sludge process. To this end, the biomass growth, system performance, flocs stealliabilityand microbial hygienic parameters were evaluated and assessed. The results highlight an optimal growth of the biomass, which reached 4.83±0.25 gTSS.l-1 and 3.68±0.2 gVSS.l-1. The activated sludge performances in term of TSS, COD, BOD5, TKN and TP were 92%, 94%, 97%, 85% and 16%, respectively. This value shows an efficient treatment of the wastewater organic pollution and nutrients by activated sludge pilot system. In addition, the treated effluent measured parameters concentrations were bellow Moroccan regulation for direct discharge into environment. The sludge volume index (SVI) average concentrations were in the range of 80 mL.g-1 to 150 mL.g-1, indicating the good folcs settleability during the experimental period. Concerning microbiological analysis, no significant reduction of all measured bacteria (p>0.05) was observed in the treated wastewater. Therefore, the concentrations of all bacteria remained practically stable after the treatment and were above Moroccan regulation guidelines for wastewater reuse in agriculture and WHO guidelines for the safe use of wastewater. The results obtained from this pilot scale study advocate that the activated sludge pilot system has performed adequately under conditions equal to its original design criteria and complained with Moroccan applied discharge standards. On other hand, to reuse treated wastewater in agriculture a disinfection process is recommended to ovoid public health and environmental contamination., Applied Journal of Environmental Engineering Science, Vol 5, No 4 (2019)

The present study reports the application of multi-soil-layering (MSL) technology for domestic wastewater treatment and reuse. Raw wastewater was collected from height rural households and used to feed MSL system (height 65 cm, diameter 40 cm). The applied hydraulic loading rate (HLR) was 250 L m-2day-1. The obtained results revealed a higher Log removal of fecal bacteria indicators (total coliforms: 1.62 Log, fecal coliforms: 1.87 Log, E. coli: 1.75 Log, fecal streptococci: 1.58 Log and intestinal enterococci: 1.54 Log) and pathogens (Pseudomonassp.: 1.77 Log, Staphylococcussp.: 1.49 Log and Clostridiumsp.: 1.96 Log).Additionally, MSL technology permitted a high removal percentage of 90, 86, 86, 83 and 90 % respectively for TSS, BOD5, COD, TN and TP. Therefore, the application of MSL technology could be considered an efficient and promising domestic wastewater treatment solution in African and developing countries to promote environmental protection and wastewater reuse., Applied Journal of Environmental Engineering Science, Vol 4, No 4 (2018)

Cadmium and mercury present in the environment, cause blood disorders. This study was conducted to evaluate the influence of cadmium, mercury and their combination on hematological parameters of Wistar rats. For this purpose, two different doses of each metal and their combination were administered orally for 28 days to six groups of five rats each. Two groups (A and B) were respectively exposed to CdCl2 (0.25 and 2.5 mg/kg), two other groups (C and D) respectively received HgCl2 (0.12 and 1.2 mg/kg) and the last two groups (E and F) were respectively treated with the combination of these two metals: (0.25 mg/kg Cd + 0.12 mg/kg Hg) and (2.5 mg/kg Cd + 1.2 mg/kg Hg). The control group (G) received the same volume of distilled water. At the end of exposure, bodies of rats were weighed and the whole blood was collected by retro-orbital sinus method for analysis of hematological parameters. The results of this study show a significant decrease (p

The objective of this work is to gauge the impact of the installation of the treatment plant on the water quality of El Azzouzia aquifer. The aquifer of El Azzouzia is located downstream of the Haouz aquifer. The water of this area was threatened by the pollution resulting from the mushrooming houses that proliferated in the region, which culminated in the degradation of the environment. According to hydrochemical analyses, electric conductivity is high in that it varies between 400 and 3200µs/cm. There is also a decrease in the majority of chemical elements in which the rates are inferior or equal to the quality standards, except for chlorides and sodium which can reach a maximum of 2300 mg/l and 1000 mg/l respectively. Another type of study that has been conducted is the isotopic study. This kind of study aims to determine the source of the elements that still mark the waters of this area. The results show that the 18O contents range from -7.89 to -5.21‰ while the 2H contents range from -52.49 to -37.05‰ indicating that the recharge area is located on an altitude that varies between 840 and 1900m, which corresponds to the Permo-Triassic evaporite formations. The degradation of the water quality sources is either from natural pollution (i.e. from the geological contributions of the aquifer recharge basin) or is anthropogenic (i.e. from the seepage of wastewater).
