Risk factors and methods for predicting ovarian hyperstimulation syndrome (ohss) in the in vitro fertilization

The current study describes the risk factors for the development of ovarian hyperstimulation syndrome and proposes a method for specific prediction of this syndrome. This study was designed to investigate 671 therapeutic cycles in the IVF program during 2009-2018. All patients were divided into two group

Construction of the equation of a state octafluorocyclobutane in area superheated steam and supercritical parameters

On the basis of the spent experimental researches of density C4F8 and given other authors the new equation of a state is constructed. The equation provides calculation of thermodynamic properties in superheated steam area and supercritical parameters of a condition octafluorocyclobutane. By means of the received equation of a condition tables of thermodynamic properties are made at temperatures 20 … 450ºС and pressure to 10 MPa. Accuracy of the presented settlement data about density is estimated by authors no more than 0,3 %. The data can be used at calculation of cycles turbine-steam the installations using octafluorocyklobutane as a working substance
