Boiling the semi-finished spicy materials for hot-pot in aluminum containers increased lead,arsenic and aluminum contents in the soup by 2.4 times,14.91% and 4.7 times,and lead,arsenic,cadmium contents in the fat by 2.3 times,62.16% and 7%,respectively.
Twelve rats were selected as normal control group and fed with ordinary diet mass of main components carbohydrate 0.6 protein 0.22 fat 0.1 others 0.08 soya bean oil especially in fat and other rats were fed with high-calorie diet mass of main components carbohydrate 0.4 protein 0.13 fat 0.4 others 0.07 animal lipid especially in fat.
A new catalyst Cu-Zn-Zr for hydrogenation of edible oils was studied. The catalyst was prepared by coprecipitation method using Cu(NO_3)_2·3H_2O,Zn(NO_3)_2·6H_2O,ZrOCl_2·8H_2 O and Na_2CO_3 as precipitant.
The layers were subjected to diets with 2% palm oil (control,2%PO), 2% linseed oil(2%LO), 4% linseed oil(4%LO), 4% fish oil(4%FO)and 4% Huoma oil(4%HO)respectively, to study the effect of different dietary oils on the performance of laying hens, content of lipid in serum and fatty acid composition of lipid in egg yolk.
The results showed that the lamellar liquid crystal and the mixed system showed higher load carrying capacity relative to the commercial grease.
The derived kinetic equation for tribochemical grease degradation allows one to predict, with a practically acceptable accuracy, the service life of the friction unit and the advancement and chemism of tribochemical processes.
An increase of the valence angle in the CH2 groups of alkane molecules is detected when the crystallites in samples of ceresin grease melt on an aluminum substrate.
These chelates are volatile enough to be analysed by gas chromatography and the separation of Th and U complexes is performed at 170°C on a column filled with glassbeads coated with DC-QF 1 silicone grease.
We studied direct drug effects on rat abdominal vagus nerve using the grease-gap technique.
