Understanding the conditions when litter beds will ignite from firebrands is critical for predicting spot fire occurrence.Such research is either field- or laboratory-based, with limited analysis to compare the approaches.We examined the ability of a laboratory method to represent field-scale ignitability.The laboratory method involved collecting l
Accurate and precise rainfall Shampoo records are crucial for hydrological applications and water resources management.The accuracy and continuity of ground-based time series rely on the density and distribution of rain gauges over territories.In the context of a decline of rain gauge distribution, how to optimize and design optimal networks is sti
Iran has a great potential for wind energy.This paper introduces optimization of 7 wind turbine blades for small and medium scales in a determined wind condition of Zabol site, Iran, where the average wind speed is considered 7 m /s.Considered wind turbines are 3 bladed and radius of 7 case study turbine blades are 4.5 m, 6.5 m, 8 m, 9 m, 10 m, 15.
As the most challenging problem of concrete, cracking does not only reduce the mechanical properties, but also jeopardize the durability and service life of concrete.Currently, to enhance the lifespan of concrete, self-healing systems are embedded in the concrete and make the concrete be capable of healing the microcracks by itself.A self-healing s
Abstract The photoswitchable poly(methyl methacrylate-random-methacrylate spirooxazine) was synthesized via atom transfer radical polymerization with the feed mole ratio of MMA/MSp comonomer of about 5.5/1.Well-defined poly(methyl methacrylate- random-methacrylate spirooxazine) have been obtained with the average molecular weight (Mn) Shampoo of 65
