Introduction. The objective of this investigation is to pinpoint the influence of the salivary pH on the hardness of the dental enamel. Method. The study was realized using recently extracted 6 non-carious wisdom teeth, that were immersed in solutions of different pH (between 2.5 and 6.5) for 3 minutes, solutions that would simulate the pH of the oral cavity in patients with a potential condition of gastroesophageal reflux disease.

One of the trends in the development of the meat industry is the introduction into the production process of modern environmentally friendly energy-saving methods for processing raw materials and semi-finished products. At the present time, attention is paid to non-traditional physical principles of processing food raw materials - electrical, magnetic, electromagnetic fields, also and electrocontact and acoustic methods. These methods have such advantages as non-inertial operation of the equipment, reduction the d...

The relevance of the research is conditioned by the need to change approaches to the formation of common criteria and mechanisms for motivating the students' abilities and readiness to effect in non-standard situations. Students have had a social and ethical responsibility for made decisions "in real time". The existing approaches are obsolete, since mutations of extraneous biological objects in the technological processes of different types of products at enterprises occur faster than before Such a situation requ...
