Voorhees, M.E., 1986. Infiltration rate of bentonite mine spoil as affected by amendments of gypsum, sawdust and inorganic fertilizer. Reclam. Reveg. Res., 5: 483-490.

A pot experiment was carried out to study the single and sequential extractions of metals in different tannery sludge amendment and the potential of the plant of Sesamum indicum L. var. T55 (sesame) for the removal of metals from tannery waste contaminated site. The metal extraction efficiency obtained with each extractants was slightly different and follow the order; EDTA>DTPA>NH(4)NO(3)>NaNO(...

We re-examine the major tenets of the informational theory of legislative rules, focusing on the informational efficiency of rules with varying degrees of restrictiveness. When committees are heterogeneous, full efficiency is attainable under the unrestrictive open rule as well as the somewhat restrictive modiÞed rule. In contrast, the restrictive closed rule always leads to inefficiencies. Whe...

As 2005 came to a close, the European Commission issued its formal proposal for a Directive amending the medical devices Directives. This article discusses certain aspects of the proposed amendments and encourages readers to review them in their entirety.

the Nuclear Regulatory Com mission (NRC) by the Society ofNuclear Medicine and the American College ofNuclear Physiciansover four years ago is finally getting some response. The reaction from the peti tion's original author, however, has been less than favorable. Carol S. Marcus, PhD, MD, Director of Nuclear Medicine and Outpatient Clinic atHarbor-UCLAMedicalCenter and the principalauthorof the...

the aim of this study was to evaluate the effect of bio-fertilizers on growth and development of plants in pots containing (v) vermicompost and (m) cow manure: (soil amendments) and (s) garden soil separately and in combination. in the first experiment, treatments included s (control), sm (soil + 15%m + 0%v), smv10 (soil + 15%m + 10%v), and smv20 (soil + 15%m + 20%v) by dry weight (w/w). in the...

Soil organic phosphorus (SOP) can greatly contribute to plantavailable P and P nutrition. The study was conducted to determine the effects of organic amendments on organic P fractions and microbiological activities in paddy soils. Samples were collected at the Changshu Agro-ecological Experiment Station in Tahu Lake Basin, China, from an experiment that has been performed from 1999 to 2004, on ...

Excessive fertilization with organic and/or inorganic P amendments to cropland increases the potential risk of P loss to surface waters. The objective of this study was to evaluate the effects of soil test P level, source, and application method of P amendments on P in runoff following soybean [Glycine max (L.) Merr.]. The treatments consisted of two rates of swine (Sus scrofa domestica) liquid...

This paper reviews general approaches for applying activated carbon (AC) amendments as an in situ sediment treatment remedy. In situ sediment treatment involves targeted placement of amendments using installation options that fall into two general approaches: 1) directly applying a thin layer of amendments (which potentially incorporates weighting or binding materials) to surface sediment, with...
