introduction: application of organic fertilizers in agricultural soils with low organic matter content is one of the best ways of nutrientsaddition to these soils. different organic fertilizers have different effects on nutrient availability in soil. moreover study of the distribution of nutrients in the soil allows investigating their mobility and bioavailability. the nutrients availability an...

Many mathematicians have investigated the properties of continued fractions. They made fraction expansions Pi number, golden ratio and many more special numbers. With help fractions, solutions some Diophantine equations are obtained. In this study, encryption was using fractional square root non-perfect-square integers. Each 29 letters in alphabet is represented by nonperfect integers starting ...

Large areas of arable lands in China have been contaminated by heavy metals, which cadmium (Cd) contamination was the most prevalent. Cd accumulation main food crops and leafy vegetables grown Cd-contaminated fields has aroused considerable attention recent years. The present study investigated pollution farmland soils Qujing city Yunnan Province, China. By comparing uptake capacities different...

this study investigated the effect of season (wet and dry) on milk composition of the dromedary camel (camelus dromedarius). milk samples representing the wet and dry seasons were analyzed for total solids (ts), fat (f), solids-non-fat (snf), ash, crude protein (cp), nitrogen soluble at ph 4.6 (sn), mineral content (mc) and casein fraction (cnf). camel milk had higher (p<0.05) fat content in th...

background: acanthamoeba keratitis (ak) is potentially a sight-threatening infection and its treatment is challenging. this is mainly due to presence of resistant cyst form. indeed, cysts are highly resistant to current available drugs. chemical drugs are toxic to human keratocytes. it should also be mentioned that most available anti- acanthamoeba drugs are poorly cysticidal, in iran and world...

Exudates produced from Bermuda grass roots were collected in deionized water from sterilized Bermuda grass sod at 3-day intervals over a period of 15 days. Exudates were analyzed for total organic carbon, and characterized via Fourier Transform Infrared Spectroscopy. Exudate samples were adjusted to pH values of 4.5, 6.5, and 7.5, amended with lead and quantified for soluble and complexed lead ...
