to achieve optimal yield and high production in wheat, need to adapt the plant's vegetative and reproductive growth stages to environmental conditions and increase use efficiency of production factors by desirable density. in order to study the effect of plant density on extinction coefficient and radiation use in modern and old wheat (triticum aestivum l.) genotypes, an experiment was conducte...

This study measured the extinction coefficients of supercritical water (SCW)-based multi-walled carbon nanotube (MWCNT) nanofluids by using an in-house developed chamber. A He–Ne laser with a wavelength 632.8 nm was employed as light source. Rod-shaped quartz diameter 3 mm and length 305 installed at top bottom chamber so that could pass through To maintain SCW-based MWCNT in chamber, designed ...

Observations of the mass and chemical composition of particles less than 2.5 microm in aerodynamic diameter (PM2.5), light extinction, and meteorology in the urban Baltimore-Washington corridor during July 1999 and July 2000 are presented and analyzed to study summertime haze formation in the mid-Atlantic region. The mass fraction of ammoniated sulfate (SO4(2-)) and carbonaceous material in PM2...
