background and objectives : mycoplasma hominis and ureaplasma urealyticum are important opportunistic pathogens that cause urogenital infections and accelerated newborn delivery in pregnant women. moreover genital mycoplasmas have been implicated in different neonatal diseases such as pneumonia, sepsis and meningitis. this study was conducted to find out the prevalence and transmission rate of ...

background the presence of an infected family member significantly increases the risk of hbv transmission, but many socio-demographic and viral characteristics of family members affect the transmission rate. objectives in this study, we have used data mining techniques to investigate the impact of different variables in intrafamilial transmission of hbv infection. patients and methods demograph...

| On Gaussian multiple{access channels a penalty in power eeciency is to be paid if total transmission rate is higher than 1 bit/s/Hz per dimension. This usually results from the need for higher order modulation schemes required to maintain or-thogonality of all users' signal waveforms. In this paper , we show that keeping binary modulation and accepting some multiple{access interference, is a ...
