The germination of Ferula ovina seeds faces certain problems. The present research was designed to study the promotion of the germination of Ferula ovina seeds by moist-chilling and GA3 applications. The results showed that Ferula ovina seeds display an endogenous dormancy that can be released by moist-chilling treatment for a certain period. In this respect, the best treatment was moist-chilli...

Development of cost-effective amendments for treating dairy slurry has become a critical problem as the number of cows on farms continues to grow and the acreage available for manure spreading continues to shrink. To determine effectiveness and optimal rates of addition of either alum or zeolite to dairy slurry, we measured ammonia emissions and resulting chemical changes in the slurry in respo...

Biochar adsorption and microbial remediation have great potential in the field of soil remediation, but since both are stressed by high concentrations toxic heavy metals when applied alone, combining two may become an effective method. In this study, application effect phosphorus-solubilizing bacteria (PSB) combined with rice husk biochar on Pb/Cd-mixed pollution form differences metal were stu...

When blood undergoes glycolysis at 37 ~ C, in addition to the loss of blood sugar, there are accompanying changes in the inorganic phosphorus. This relationship has been investigated and reported by a number of authors (2, 8, 9, 10). They agree that during the first 4 hours of glycolysis, the inorganic phosphorus of the blood in normal individuals either remains at a constant level, or is only ...

The effect of chickpea (Cicer arietinum L.) processing methods on the nutritive utilization of calcium and phosphorus and on phytic acid, a seed component that affects mineral utilization, was studied. Chemical and biological methods were used for nutritional determinations in growing rats. The digestive utilization of calcium from raw chickpea was adequate for growing rats; however, processing...

The existence of a fat-soluble dietary factor essential for guinea pig nutrition was well established through investigations by Wulzen and Bahrs (l-3) and has been confirmed by Anderson and Caldwell.’ The isolation of a highly active fraction from raw cream, capable of alleviating an induced stiffness in guinea pigs, was described by van Wagtendonk and Wulzen (4). It seems apparent from physiol...

Recent advances in monitoring technology have enabled high frequency, in-situ measurements of total phosphorus and total reactive phosphorus to be undertaken with high precision, whilst turbidity can provide an excellent surrogate for suspended sediment. Despite these measurements being fundamental to understanding the mechanisms and flow paths that deliver these constituents to river networks,...

Removal of nitrogen and phosphorus is known to be somewhat problematic in vertical subsurface flow (VSSF)constructed wetlands. In this pilot-scale study, two planted (Typha latifolia L. [cattail]) VSSF-constructed wetlands A (with polypropylene pellets) and B (without polypropylene pellets) and one unplanted control C (without polypropylene pellets) were designed to test the contribution of pol...
