Four experiments were conducted to evaluate lipid digestibility in finishing swine fed chemically hydrogenated fats. Dietary chromic oxide was used as an inert marker to measure the apparent digestibility of supplemental fat (SF) that consisted of fully hydrogenated (FH), partially hydrogenated (PH), or PH products blended with other fat sources. In Exp. 1, diets containing 5% SF (as-fed basis)...

The very low level of postillumination ATP synthesis in chromatophores was markedly stimulated when permeant anions (thiocyanate or perchlorate) or permeant cations (potassium in the presence of valinomycin) were added to the light stage. Although these compounds stimulated also light-induced proton uptake in chromatophores the pH dependence of both photoreactions was different. Proton uptake p...

We investigated the influence of the pH value, precursor concentration (C), growth time and temperature on the morphology of zinc oxide (ZnO) nanostructures. The pH of the starting solution was varied from 1.8 to 12.5. It was found that the final pH reaches an inherent value of 6.6 independently of the initial pH solution. Various ZnO structures of nanotetrapod-like, flower-like, and urchin-lik...

The objective of the study was to characterize pale breast meat, compare it with normal colored breast meat, and determine whether it should be considered pale, soft, and exudative (PSE). Characteristics of 20 normal and 20 pale broiler breasts, obtained at a commercial slaughter plant, were evaluated. Compared with normal meat, the pale breast meat had a significantly (P < 0.05) lower pH (5.7 ...

The electrical conductivity of black phosphatidylserine membranes, in solutions of 100 mM NaCl, 10 mM sodium phosphate (pH 7.1), is strongly increased by the intrinsic proteins ("strongly bound" protein fraction) from human erythrocyte membranes. The magnitude of the conductivity increase is highly dependent on the maximum pH-value pH used during the preparation of the protein (8.0 less than or...

A retrospective study to determine how well cardiotocogram (CTG) and micro blood analysis (FBA) results correspond to each other was made on 200 deliveries which had been monitored sub partu by these techniques. FBA was performed 306 times. CTG results were analysed according to Hammacher's method and the scores compared with the FBA results. In 40 cases with a normal Hammacher score, a normal ...

AIM pH is the direct indicator of the body reaction following the activities performed. Establishing precise correlations between pH and blood biochemical parameters might support the balancing of values during periods of marked physical activity. METHOD We conducted a case study in a group of elite rowers. Twelve athletes were included in the study. Monitoring was carried out by collecting b...

The aim of this paper is to present approximated model of pH process applicable for simulation and control. The highly nonlinear dynamical properties of the pH value to the addition of acid or base make the pH control very difficult. Changes in process sensitivity with pH makes difficult to design conventional controllers. Proposed pH model approximation allows formulating advanced control algo...
