IIn order to study the effects of increasing level of metabolizable energy and protein on feed intake, improve nutrient digestibility, performance and blood metabolites of Zell pregnant ewes at late gestation, 32 pregnant ewe (mean body weight 42.1 kg, 2.5 years-old, multiparous, 100 days of pregnancy) were used in completely randomized design with 4 treatments and 8 replicates. Treatments were...
OBJECTIVE The present study evaluates the reliability and validity of an FFQ designed for use with adolescents in urban Vietnam. DESIGN A cohort study was conducted between December 2003 and June 2004. The FFQ was administered three times over a 6-month period (FFQ 1-3) and nutrient intakes were compared to those obtained from four 24 h recalls collected over the same period (24 h recalls 1-4...
Dietary Reference Intakes (DRIs) are nutrient standards that may be used to plan nutrient intakes. Thus, they are useful as the basis for formulating dietary guidelines. The guidelines are often presented to the public as a food guide that will promote nutrient adequacy without risk of excessive intake. Such guides typically use the Recommended Dietary Allowances (RDAs) as intake targets becaus...
according to cheng (1999), in recent esl/efl literature, asian (especially east asian) learners of english as a foreign/second language have been arguably reported as reticent and passive learners. the most common allegations are that these students are reluctant to participate in classroom discourse; they are unwilling to give responses; they do not ask questions; and they are passive and over...
The nutrient elements uptake in many of soils, is a problem because of high pH and plenty of calcium ions in them. Some of these elements are phosphorus and microelements. It is possible to increase absorption of these nutrient elements by addition of sulfur in soil and biological oxidation. The rate of this reaction is very slow and Thiobacillus bacteria are the most important oxidators of sul...
We report results from a series of studies coevolving players for simple Rock–Paper–Scissors games. These results demonstrate that “Current Individual versus Ancestral Opponent” (CIAO) plots, which have been proposed as a visualization technique for detecting both coevolutionary progress and coevolutionary cycling, suffer from ambiguity with respect to an important but rarely discussed class of...

BACKGROUND Compared to food patterns, nutrient patterns have been rarely used particularly at international level. We studied, in the context of a multi-center study with heterogeneous data, the methodological challenges regarding pattern analyses. METHODOLOGY/PRINCIPAL FINDINGS We identified nutrient patterns from food frequency questionnaires (FFQ) in the European Prospective Investigation ...

Water deficit conditions, in addition to reduced water uptake, result in a reduction in nutrient uptake, and consequently, a substantial reduction in growth parameters, yield and quality. Substrate inoculation with arbuscular mycorrhizal fungi (AMF) as an environmentally friendly biofertilizer is an important strategy to improve the growth parameters and quality of products in such conditions. ...
