Liquid manure (slurry) storages are sources of gases such as ammonia (NH(3)) and methane (CH(4)). Danish slurry storages are required to be covered to reduce NH(3) emissions and often a floating crust of straw is applied. This study investigated whether physical properties of the crust or crust microbiology had an effect on the emission of the potent greenhouse gases CH(4) and nitrous oxide (N(...

The primary goal of the Florida Atmospheric Mercury Study (FAMS) was to quantify the atmospheric deposition of Hg throughout Florida. Monthly integrated precipitation and weekly integrated particulate samples were collected at 10 sites in Florida for periods ranging from 2 to 5 yr. The monthly rainfall across the state and the concentrations of Hg in wet-only and bulk deposition increased by a ...

Putman, C. T., M. P. Matsos, E. Hultman, N. L. Jones, and G. J. F. Heigenhauser. Pyruvate dehydrogenase activation in inactive muscle during and after maximal exercise in men. Am. J. Physiol. 276 (Endocrinol. Metab. 39): E483– E488, 1999.—Pyruvate dehydrogenase activity (PDHa) and acetyl-group accumulation were examined in the inactive deltoid muscle in response to maximal leg exercise in men. ...

Pyruvate dehydrogenase activity (PDHa) and acetyl-group accumulation were examined in the inactive deltoid muscle in response to maximal leg exercise in men. Seven subjects completed three consecutive 30-s bouts of maximal isokinetic cycling, with 4-min rest intervals between bouts. Biopsies of the deltoid were obtained before exercise, after bouts 1 and 3, and after 15 min of rest recovery. In...

Acrolein is a urinary metabolite of cyclophosphamide and ifosfamide, which has been reported to be the causative agent of hemorrhagic cystitis induced by these compounds. A direct cytotoxic effect of acrolein, however, has not yet been demonstrated. In the present study, the effects of intravesical injection of acrolein and mesna, the classical acrolein chemical inhibitor, were evaluated. Male ...

OBJECTIVE To determine the optimized protocol for wet monopolar radiofrequency ablation (RFA) using a perfused-cooled electrode to induce coagulation necrosis in the ex vivo bovine liver. MATERIALS AND METHODS Radiofrequency was applied to excised bovine livers in a monopolar mode using a 200W generator with an internally cooled electrode (groups A and B) or a perfused-cooled electrode (group...

The petroleum industry requires the best materials to reverse the rock wettability to water-wet state which give significantly improved oil recovery.Nanoparticles are suggested as enhanced oil recovery potential agents to decrease viscosity and alter the wettability of reservoir towards more water-wet. This study provides new insights into CuO nanoparticles effects on wett...

BACKGROUND AND AIMS Intestinal failure defined by the minimal energy and wet weight absorption required to avoid home parenteral nutrition (HPN) is not well described. Thus the aim of this study was to identify the minimal level of gut function necessary to avoid parenteral support using objective measurements of intestinal function. METHODS Energy (bomb calorimetry) and wet weight absorption...

Beef finishing and dairy lactation experiments were conducted to evaluate the nutritional value of distillers grains (DG) from sorghum or corn fermentation, in both wet (35.4% DM) and dry (92.2% DM) form (dairy trial only). In the finishing experiment, 60 yearling steers were used in a completely randomized design with three diets that were fed for 127 d: 1) control diet with 86% (DM basis) dry...

Physiol. 86(5): 1745–1748, 1999.—To investigate the effects of training in normoxia vs. training in normobaric hypoxia (fraction of inspired O2 5 20.9 vs. 13.5%, respectively) on the regulation of Na1-K1-ATPase pump concentration in ...
