This study stabilizes and bloats Cr(VI)-sorbed bentonite by heating at high temperature. Cr leaching decreases with increasing temperatures. Heating the sample at 1100 1C results in a non-detectable Cr concentration in the leachate, equivalent to a Cr leaching percent less than 0.001% (i.e., Cr TCLP concentration o0.018mg of Cr L 1 of leachate). Morphology observed with a scanning electron micr...

Reaction of chromium(VI) with one equivalent of ascorbate was studied by electron paramagnetic resonance spectroscopy in the presence of 0.10 M 5,5-dimethyl-1-pyrroline-1-oxide (DMPO) at room temperature in 0.10 M (N-[2-hydroxyethyl]piperazine-N'-[2-ethanesulfonic acid]) (HEPES) and 0.05 M tris(hydroxymethyl)aminomethane hydrochloride (Tris-HCl) buffers (pH 7.0 room temperature). Chromium(V), a...

The Kuo condition and the second are known as criteria for an r-jet to be V-sufficient in Cr mappings Cr+1 mappings, respectively. In [2] we considered notions of V-sufficiency jets these conditions relative case a given closed set ?, showed that is criterion ?-V-sufficient sufficient mappings. this paper discuss several equivalent or condition.

CONTEXT It has been difficult to distinguish the independent effects of caloric restriction versus exercise training on insulin resistance. OBJECTIVE Utilizing metabolic feeding and supervised exercise training, we examined the influence of caloric restriction vs. exercise training with and without weight loss on hepatic and peripheral insulin resistance. DESIGN, PARTICIPANTS, AND INTERVENT...

The main result of this paper is that the identity component of the automorphism group of a compact, connected, strictly pseudoconvex CR manifold is compact unless the manifold is CR equivalent to the standard sphere. In dimensions greater than 3, it has been pointed out by D. Burns that this result follows from known results on biholomorphism groups of complex manifolds with boundary and the f...

Objective: The aim of present study was to evaluate the effects of oral administration of gallic acid (GA) for 21 days alone and in combination with exercise on nerve conduction velocity and sensory and motor functions in rats with sciatic nerve crush. Materials and Methods: Seventy adult male Wistar rats (250-300 g) were divided randomly into 7 groups with 10 in each: 1) Control (Cont), 2) Cru...

The effects of Cr, Mo and W on the crevice corrosion of a number of commercial Ni-Cr-Mo (W) alloys in 1.0 mol/L NaCl were studied using the potentiodynamic-galvanostaticpotentiodynamic technique to measure film breakdown and repassivation potentials as well as protection temperatures. As expected, Cr is the key element determining resistance to crevice initiation but a substantial Mo alloy cont...

Let M ⊂ Cn+1 (n ≥ 2) be a real analytic submanifold defined by an equation of the form: w = |z|2 + O(|z|3), where we use (z,w) ∈ C × C for the coordinates of Cn+1. We first derive a pseudo-normal form for M near 0. We then use it to prove that (M, 0) is holomorphically equivalent to the quadric (M∞ : w = |z|2, 0) if and only if it can be formally transformed to (M∞, 0). We also use it to give a...
