The relationships between grain yields and whole-plant accumulation of micronutrients such as zinc (Zn), iron (Fe), manganese (Mn) and copper (Cu) in maize (Zea mays L.) were investigated by studying their reciprocal internal efficiencies (RIEs, g of micronutrient requirement in plant dry matter per Mg of grain). Field experiments were conducted from 2008 to 2011 in North China to evaluate RIEs...

The use of distillers byproducts as energy sources would expand the market for these byproducts. Drying of these byproducts may produce changes that affect the nutritional value. A series of experiments was conducted to evaluate distillers byproducts as an energy source for finishing cattle and to compare wet vs. dried byproducts. The energy value of wet distillers byproducts was 132 to 174% th...

effects of water stress and fusarium oxysporum f. sp. lycoperseci (fol) on the growth of tomatoes were studied in a greenhouse experiment. treatments consisted of five levels of water stress (1, 3, 5, 7 and 9 day irrigation intervals). infested soil consisting of 400 chlamydospores g1 of fol and non infested soil were used. experiments arranged in a completely randomized design with 8 replicati...

The effect of different amounts of rainfall on the below-ground plant biomass was studied in three grassland ecosystems. Responses of the lowland (dry Festuca grassland), highland (wet Cirsium grassland), and mountain (Nardus grassland) grasslands were studied during five years (2006-2010). A field experiment based on rainout shelters and gravity irrigation simulated three climate scenarios: ra...

Complete wetting is a universal phenomenon associated with interfaces separating coexisting phases. For example, in the pure gluon theory , at T c an interface separating two distinct high-temperature de-confined phases splits into two confined-deconfined interfaces with a complete wetting layer of confined phase between them. In supersym-metric Yang-Mills theory, distinct confined phases may c...

In 27 pentobarbital-anesthetized cats cerebral blood flow and regulation of cerebral blood flow was measured one to 3 weeks following stereotactical xenotransplantation of a rat glioma clone into the internal capsula. Tumor growth was accompanied by severe vasogenic peritumoral edema in the white matter of the tumor-bearing hemisphere. White matter water content in the vicinity of the tumor inc...

MR phase images have shown significantly improved contrast between cortical gray and white matter regions compared to magnitude images obtained with gradient echo sequences. A variety of underlying biophysical mechanisms (including iron, blood, myelin content, macromolecular chemical exchange, and fiber orientation) have been suggested to account for this observation but assessing the individua...
