HYDRODYNAMIC PRESSURE OPTIMIZATION METHOD IN A WELL AT ROUND-TRIP OPERATIONS
DescriptionThe aim of the article is to study the effect of velocity and acceleration of a drill string on hydrodynamic pressure in a well. We obtain the formulas of pressure versus time. We also established the method for optimizing hydrodynamic pressure in a well at round-trip operations

STATE AND PROSPECTS OF DATA STREAMING FROM A WEB-BROWSER IN ORDER TO CREATE A CLOUD CALL CENTER
DescriptionThe article gives an overview of possible deployment models of a cloud call center. The requirements for the interaction with VoIP telephony are proposed and the features of SIP, RTP, UDP protocols are described. The article describes the current capabilities of data streaming through a web browser using different approaches: the browser add-on, Adobe Flash technology and WebRTC protocol . In conclusion, the comparison of the existing solutions for data streaming through a web-browser to VoIP telephony is presented

DYNAMIC OF SANITARY CONDITION OF PINE (PINUS SILVESTRIS L.) PLANTINGS DAMAGED BY GROUND FIRE
DescriptionIn the article we have assessed the sanitary condition of pine (Pinus silvestris L.) in the territory of Suburban forestry of Voronezh region affected by fires in 2010. The results indicate about the inevitable death of pine plantations damaged by strong ground fire
-
Description
The article demonstrates the taxation parameters of the pine plantations that was damaged by fire in 2010 in Suburban forestry of the Voronezh region and was calculated the basic ecological functions they performed before death. The intercommunication was found between increasing level of air pollution in the study areas and growing of heart and pulmonary morbidity of population
-
Description
In the article, we made an estimation of pine cultures’ (Pinus silvestris L.) sanitary condition in the Savalsky Forestry area of the Voronezh region. The obtained results show their considerable weakness, passing to the drying phase because of pine fungus

Description
The possibility of the ISSR-markers application for systematization and genetic certification of the genus Rhododendron is showed on the basis the research of 25 species and intraspecific taxons. The way of recording of genetic passport on the basis of amplicons size is suggested

ISSR ANALYSIS OF PINUS SYLVESTRIS TREES APPURTENANT TO DIFFERENT SELECTION CATEGORIES
DescriptionThe genetic variability study of Pinus sylvestris trees appurtenant to different selection categories in the plus stand is carried out with ISSR markers. A total of 178 loci were amplified by 6 ISSR – primers and 168 of them were polymorphic. It is detected that the genetic distance between the trees appurtenant to difference selection categories varies from 0,038 to 0,082. Genetic variation parameters of the Pinus sylvestris plus stand are calculated. Shannon’s index (I) was 0,4303, Nei’s gene diversity (H) was 0,2735 and Effective number of alleles (Ne) was 1.4268
