Modelling the hydrological balance in semi-arid zones is essential for effective water resource management,encompassing both surface water and *** study aims to model the monthly hydrological water cycle in the Wadi Mina upstream watershed(northwest Algeria)by applying the Soil and Water Assessment Tool(SWAT)hydrological *** modelling integrates spatial data such as the Digital elevation Model(DEM),land use,soil types and various meteorological parameters including precipitation,maximum and minimum temperatures,relative humidity,solar radiation and wind *** SWAT model was calibrated and validated using data from January 2012 to December 2014,with a calibra-tion period from January 2012 to August 2013 and a validation period from September 2013 to December *** and parameter calibration were conducted using the SWAT-SA program,and model performance evaluation relied on comparing the observed discharge at the outlet of the basin with model-simulated discharge,assessed through statistical coefficients including Nash-Sutcliffe Efficiency(NSE),coefficient of determination(R2)and Percent Bias(PBAIS).Calibration results indicated favourable objec-tive function values(NSE=0.79,R2=0.93,PBAIS=-8.53%),although a slight decrease was observed during validation(NSE=0.69,R2=0.86,and PBAIS=-11.41%).The application of the SWAT model to the Wadi Mina upstream watershed highlighted its utility in simulating the spatial distribution of different components of the hydrological balance in this *** SWAT model revealed that approximately 71%of the precipitation in the basin evaporates,while only 29%contributes to surface runoff or infiltration into the soil.

Antidiabetic effect of Opuntia dillenii seed oil on streptozotocin-induced diabetic rats

Asian Pacific Journal of Tropical Biomedicine 2019年第9期9卷 381-388页

作者： Mohamed Bouhrim Hayat Ouassou el Hassania Loukili mohammed Ramdani Hassane Mekhfi Abderrahim Ziyyat Abdelkhaleq Legssyer mohammed Aziz Mohamed Bnouham Faculty of Sciences University Mohamed first

Objective: To assess the antidiabetic effect of Opuntia dillenii seed oil on rats with diabetes mellitus. Methods: A rat diabetes model was established by intraperitoneal injection of rats with 50 mg/kg streptozotocin. Thirty albino Wistar rats were divided into five groups: the diabetic control group and normal control group were treated only with distilled water, two diabetic groups received 1 and 2 m L/kg of oil per day, respectively, for 30 days and one diabetic group received 2 mg/kg of glibenclamide. In addition, blood glucose was determined weekly. Body weight, average daily food, water intake and urinary volume of each animal were determined before and after the treatment period. After the treatment period, hepatic glycogen was determined using the anthrone reagent, and glycosuria, total cholesterol, triglycerides, alanine aminotransferase, aspartate aminotransferase, urea, creatinine and uric acid were estimated using common clinical diagnostic kits. Results: Oral intake of the oil at 1 and 2 m L/kg for the diabetic animals significantly diminished blood glucose, glycosuria, total cholesterol, triglycerides, alanine aminotransferase, aspartate aminotransferase, urea, creatinine and uric acid, accompanied by a noticeable elevation in the amount of hepatic glycogen in comparison with the diabetic control group. Similarly, Opuntia dillenii seed oil significantly increased the food intake and decreased the urinary volume per day in treated rats of the same groups in comparison with the period before the treatment intervention and attenuated body weight loss in the diabetic rats. Moreover, this effect of the oil was dose dependent. On the other hand, the oil did not affect their need for water. Conclusions: The results show that Opuntia dillenii seed oil has a very important antidiabetic effect on streptozotocin-induced diabetic rats. Hence, we suggest it as a preventive control of diabetes mellitus.

作者： Fatima Zahra el Mechtali Hamid Essabir Souad Nekhlaoui mohammed Ouadi Bensalah Mohammad Jawaid Rachid Bouhfid AbouEIkacem Qaiss Laboratory of Mechanic and Materials (LMM) Mohammed V-Rabat University Faculty of Science Rabat Morocco Moroccan Foundation for Advanced Science Innovation and Research (MAScIR) Institute of Nanomaterials and Nanotechnology (NANOTECH) Laboratory of Polymer Processing Rabat Morocco Laboratory of Mechanics in Processes Energy and Environment National School of Applied Sciences Ibn Zohr University Agadir Morocco Department of Biocomposite Technology Institute of Tropical Forestry and Forest Products (INTROP) Universiti Putra Malaysia 43400 UPM Serdang Selangor Malaysia

Polypropylene （PP） matrix composites reinforced with chemically treated Almond Shell （AS） particles with and without compatibilizer （PP-g-MA） was prepared by a twin-screw extrusion at loading of 20 wt.% AS particles. Two types of chemical treatments （alkali treatment with sodium hydroxide and etherification with dodecane bromide） of the particles were carried out to improve the interface adhesion between particles and PP matrix. Results show that chemical modifications of AS particles affect the mechanical and viscoelastic properties of AS/PP composites. The composites reinforced with alkali treated particles and the compatibilized matrix lead to a notable increase in the Young＇s modulus （14%） compared to the composites with untreated AS particles. The ductility of composite was also evaluated by the yield strain, and results show a notable increase （31%） compared to that of composites with untreated particles. The thermal stability increased with the use of etherification （385 ℃）, with gains in the temperature up to 23 ℃ compared to neat PP （362 ℃）. The achieved results show that the AS/PP composites can be used in several applications. A thermoplastic matrix compsite mixed with treated AS particles appears to be a good alternative to obtain environmentally friendly products.
