Land surface evapotranspiration (LET) from typical river basins in China in the years 1991, 1995 and 1999, was modelled with a quantitative remote sensing method, which is based on a modified version of the Surface Energy Balance System (SEBS) model. LET simulations were conducted on several river basins, and validations demonstrated good agreement with observational data on all basins, except ...
The preparation of side group modified polystyrene-based surface-active block copolymers (SABC) for use as marine fouling resistance/release applications is described. Modifying moieties such as poly(ethylene glycol) (PEG) and semifluorinated segments were used. A novel bilayer methodology has been employed that provides both suitable mechanical properties through the use of an elastomeric prim...
Evapotranspiration (ET) plays a significant role in regional and global climates through its partitioning in hydrological cycles, and its estimation is thus of a great importance in assessing ground water and surface water resources, predicting crop yield and planning land use. For experimenting the possibility to assess the hydrological responses of ecological restoration in the Western Chines...
Smart materials with reversible wettability have attracted a lot of attention for application in sewage treatment. In this work, pH-responsive polymer was prepared via the one-step free radical polymerization 3-(trimethoxysilyl) acrylate and 2-dimethylaminoethyl methacrylate. The obtained then coated hydrogenated styrene–ethylene–butadiene–styrene block copolymer to endow material switchable su...
هدف از این پژوهش، بررسی اثر نانوذرات خاک رس (cloisite® 15a) بر رفتار جریان و خواص مکانیکی و گرمایی آمیخته پلی پروپیلن/کوپلیمر (استیرن - اتیلن - بوتیلن - استیرن) پیوند خورده با مالئیک انیدرید sebs-g-ma)، ۱۵% وزنی) است. بدین منظور، کامپوزیتهایی برپایه این آمیخته و مقادیر مختلف خاک رس (۱، ۳ و ۵% وزنی) با استفاده از مخلوط کن داخلی در دمای ۱۹۰ درجه سلسیوس و سرعت چرخش ۷۵ دور بر دقیقه به مدت ۱۲ دقی...
