This work identifies the main phenomena that control the peptisation and transport of clay particles in a sand core. Clay can be dispersed into small particles in an aqueous solution of low ionic strength. This property is used to generate clay particles with NaCl concentration varying from 0.5 M to 0.015 M. For this purpose, a chromatographic column is initially packed with a 5 % clay-sand mix...

Heparin can inhibit the Limulus test for endotoxin unless 0.05 M CaCl(2) and 0.154 M NaCl are added to the lysate.

We evaluated the combined use of 0 or 4 mg/d of recombinant porcine somatotropin (pST) and 0 or 2.75 ppm salbutamol in three genotypes of growing barrows (139 d old) differing in lean and lipid accretion potential. Treatments were in a 2 x 2 x 3 factorial arrangement, and the three genotypes tested were Meishan (M, n = 32, 49 kg), Duroc x White composite (D x Wc, n = 31, 62 kg), and Meishan x W...

In a 4-yr study, molasses (M; 6% CP), molasses-urea (MU; 17.5% CP; 92% molasses, 4% urea and 4% water) and molasses-cottonseed meal-urea (MCSM; 17.5% CP; 73% molasses, 25% cottonseed meal, 1% urea and 1% water) were compared as winter supplements for Braford cows (514 matings) consuming low-quality forage. Cows were fed 1.35, 1.50 and 1.27 kg.head-1.d-1 of the respective supplements for 127 d b...

The photosynthetic oxygen-evolving activity of the photosystem 2 complex, prepared from spinach, was labile when the complex was exposed to high-salt conditions under which the extrinsic proteins were dissociated from the complex. Glycinebetaine prevented the dissociation of the 18-kDa and the 23-kDa extrinsic proteins from the photosystem 2 complex in the presence of 1 M NaCl. It also prevente...

This deliverable constitutes Major Project Milestone M5. It consists of the ACGT Master Ontology (OWL file) accompanied by comments regarding technical details, principles of ontology development employed the role of the ontology for other elements of the ACGT framework, and the possibilities of maintenance and extension of the ontology. KEYWORD LIST: Ontology, Ontology Development, Ontology Ma...

It is widely accepted that the inhibition of gastric motor activity as well as the maintenance of gastric mucosal blood flow and mucous secretion are important for the homeostasis of the gastric mucosa. The present study was performed to ascertain whether or not endogenous PGs, which can protect the stomach from noxious stimuli, affect gastric motor activity and emptying. The myoelectrical acti...

BACKGROUND Hyperkalemia is a frequently observed electrolyte imbalance in dehydrated neonatal diarrheic calves that can result in skeletal muscle weakness and life-threatening cardiac conduction abnormalities and arrhythmias. HYPOTHESIS Intravenous administration of a small-volume hypertonic NaHCO3 solution is clinically more effective in decreasing the plasma potassium concentration (cK) in ...

SKADHAWCE, E., AND S. Il. BRADSHAW. Saline drinking and cloacal excretion of salt and zvater in the zebra finch. Am. J. Physiol. 227(6) : 1263-1267. 1974.-Zebra finches (‘Ihenio@ygia castanotis) from Western Australia were studied in order to investigate whether wild-caught animals were able to concentrate their urine to a higher degree than domesticated birds and whether they could drink fluid...
