The "Tehran Blood Pressure Study" (TBPS) is an observational cross-sectional study performed on men and women aged 15 years or more during the years 1990-1991. The study has been designed and performed by the Tehran University of Medical Sciences' Cardiovascular Research Center, with the primary objective of determining the prevalence and distribution of high blood pressure in Tehrani adult...
The paper considers some possible input data of NPP power unit model for solving the problem state matching with prototype state. In course work on prototype, a numerical experiment using full-scale modeling complex PROSTOR was conducted. Its essence to obtain steady states capacity from 94% 104% step 0,05%. For we used Kalinin 3 loading 4 248 effective days. When analyzing results experiment, ...
An intrathoracic pressure regulator (ITPR) is a device that can be added to the external end of a tracheal tube to create controlled negative airway pressure between positive pressure ventilations. The resulting downward bias of the airway pressure baseline promotes increased venous return and enhanced circulation during CPR and also during hypovolemic shock. In the present study, we exercised ...
A high-pressure dilatometer capable of measuring volume changes of 2 X loo6 cm3 is described. Fractional volume changes of 1 part in lo4 can be measured over a temperature range of 30-90 “C, and a pressure range of 1 bar (0.1 MPa)-3 kbar (300 MPa). The dilatometer is constructed out of a commercial high-pressure valve and a compact home-built pressure sensor. The system was specially designed t...
