The possibility of establishing the varietal and territorial affiliation of wines by the content of rare earth elements (REE) in them was studied. ICP-OES and ICP-MS with subsequent chemometric processing of the results were applied to determine the elemental image of soils containing negligible REE amounts, grapes grown on these soils, and wine materials of Cabernet Sauvignon, Merlot, and Moldova varieties produced from these grapes. To stabilize and clarify wine materials, the traditional processing of wine materials with various types of bentonite clays (BT) was used, which turned out to be a source of REE in the wine material.

In the present paper, we present a concept of internal airlift for oil medium with dissolved gas which could be propelled by external acoustic field. The mechanism determining gas bubble size as a function of pressure change is discussed.

The features of cerebral circulation and myocardium functional condition of teenagers are studied depending on initial tonus of the autonomic nervous system and locomotor activity level in the process of continuous step physical activity on tredmil. The condition of regulatory mechanisms, providing adaptation of teenagers in the conditions of modern school was studied.

During the 4-week trial, the Blueberin supplement was administered three times per day, 15-30 minutes prior to a meal along with 100 ml of water. Results of this trial revealed that the supplementation of Blueberin reduced fasting plasma glucose from 143+/-5,2mg/L to 104+/-5,7 mg/L (p<0,001), whereas there was no statistically significant changes in the Placebo group from 138+/-4,8 mg/L to 126+/-5,1mg/L (p>0,05).
