Because vanadium (V) is easily reduced to a cationic form within plant cells, data from resin-extraction of soil were analysed for evidence 5 of interactions between V and the resin-extractable concentrations of magnesium (Mg) and calcium (Ca) on soybean seed yield. Three varieties, 9091, 9061 and 704, were grown over a 3-year period in a corn± soybean±wheat rotation. Surface soil samples (0±15...

Two populations of nuclear androgen receptors have been characterized in human prostatic tissue, and the levels and proportions of each were found to differ in normal prostates, benign hyperplastic prostates (BPH), and malignant prostates. A significant percentage (35 to 50%) of total nuclear androgen receptors was associated with the salt-resistant nuclear matrix fraction. The remainder were e...

Background: As the decomposition of lignocellulosic compounds is a rate-limiting stage in the nutrient mineralization from organic matters, elucidation of the changes in soil enzyme activity can provide insight into the nutrient dynamics and ecosystem functioning. The current study aimed to assess the effect of thinning intensities on soil conditions. Un-thinned control, 20 % thinning, and 30 %...

Certain organic carbon moieties in drinking source waters of the Sacramento-San Joaquin Delta can react with chlorine during disinfection to form potentially carcinogenic and mutagenic trihalomethanes. The properties of reactive organic carbon in Delta waters, particularly those of soil origin, have been poorly understood. This study attempts to characterize trihalomethane reactivity of soil or...

Solidification and stabilization (S/S) by agents stabilizers is an effective way to treat heavy metal-contaminated sediments. Optimization of curing condition crucial minimize the consumption reagents on base S/S. In this work, synergistic effects cement stabilizer mechanical strength leaching toxicity contaminated sediments were investigated, S/S conditions optimized using response surface met...

An existing sequential extraction scheme for particulate iron (Fe) is evaluated manganese (Mn) using a range of Mn standards. The consists 5 steps and quantifies operationally defined pools (1) poorly ordered oxides phosphates (ascorbic acid extractable); (2) carbonates sulfides (1 M HCl extractable), (3 4) crystalline (citrate buffered dithionite ammonium oxalate extractable, respectively) (5)...
