Abstract Aridity regulates the terrestrial ecosystem productivity in water-limited regions. The aridity index (AI) is often defined as ratio of annual precipitation to potential evapotranspiration. However, how drying and wetting influence vegetation response its characteristic along gradient remains unclear. Here, we examined trends AI normalized difference (NDVI) drylands East Asia from 1982 ...

Abstract Collapsible soils are almost found in unsaturated states and involved significant engineering problems. Geotechnical challenges of such represented by the hydro-mechanical behaviour during wetting–drying cycles due to humidity climate conditions. The main objective this paper is investigate soil–water characteristic curve (SWCC) collapsible soils. In study, three types were investigate...

Various types of fibers like glass, steel, coconut fiber, sugarcane bagasse etc are used to increase the mechanical properties concrete. SCBF is final residue sugar industries which in this study. The objective paper study effect geopolymer concrete (GPC) and conventional (CC) equivalent grade M40 when it subjected alternative drying wetting. specimens treated with water by wetting process. Thi...

The experiment was conducted in the Sher-e-Bangla Agricultural University research farm, Dhaka, Bangladesh during December 2010 to April 2011 to study the effect of fertilizer and manure with different water management on the growth, yield and nutrient concentration of BRRI dhan28. The experiment consisted of 2 factors i.e. irrigation and fertilizer plus manure. There were 2 irrigation levels (...

The role of water in hardened Portland cement paste (hpc) is germane to an understanding of the nature of nanostructure – property relationships. The irreversible dimensional changes of hpc that occur on wetting and drying are dissimilar to those observed for other silicate minerals of interest to cement science. This irreversibility is also observed for the modulus of elasticity parameter. Len...

We have introduced a novel solvent-based method to roughen polymer surfaces and characterized treated polypropylene (PP). The consists of three main steps: solvent treatment, drying, peeling. investigated the effects process parameters such as time immersion in solvent, temperature, drying temperature on surface morphology created. structure formed is mainly influenced by temperature. also wett...
