conclusion hsg is considered to have a high sensitivity and specificity. hsg and laparoscopy are not alternative, but are the complementary methods in the examination of no tubal patency. results the sensitivity and specificity of hsg on bilateral tubal patency or no bilateral tubal patency were 92.1% and 85.7% respectively. the positive and negative predictive values were 97.2% and 66.7%, and ...

this paper presents a control model of the hydroforming and the dual hydroforming process of atube. the theoretical part includes calculations to measure the change in tube thickness through thedeveloped process. the hydroforming and the dual hydroforming processes are simulated in thesolidsimulation software and the static and the dynamic simulations are modeled. theobtained results for the t-...

heat exchangers are one of the most important devices of mechanical systems in modernsociety. most industrial processes involve the transfer of heat and more often they requirethe heat transfer process to be controlled. a heat exchanger is the heat exchanged betweentwo media, one being cold and the other being hot. there are different types of heatexchanger, but the type which is widely used in...

in this investigation the effects of excess vitamin a administration during the early embryonic period were studied. intramuscular injection of a single dose of 15000,20000 or 25000 iu/kg vitamin a to pregnant balb/c strain mice on either day 7,8,9 or 10 of gestation (vaginal plug= day 0 of gestation) produced major malformations in the central nervous system (cns) including exencephaly, hydroc...
