Abstract Total Electron Content (TEC) is central to characterizing ionospheric response to solar and geomagnetic activity.Variations in TEC structures over time provide insight into underlying physical processes and inform monitoring of space weather events, which pose a risk to navigation and communication systems.JPL processed GNSS observations o
The article gives the arguments proving necessity of evaluating the software quality costs.Questions of evaluating the software quality costs Commercial Ranges were considered.Various techniques to ensure the software quality were analyzed.A description of the method of Quality Function Deployment was given.The possibility of using the method of So
There has been an increased interest in true potato seeds (TPS) as planting material because of their advantages over seed tubers.TPS produced from a tetraploid heterozygous bi-parental population produces non-uniform segregating progenies, Girls Bikini which have had limited uniformity in yield and quality in commercial cultivation, and, thus, lim
Introduction: Considering the importance of co-culture in differentiation of embryonic stem cells, the aim of this study was evaluation of the effect of co-culturing fetal liver stroma cells with P19 MYRRH GUM cells on the line of differentiation.Materials and Methods: For this purpose, P19 cells were cultured directly in semisolid medium.These cel
