the solubility of co2 in the primary, secondary, tertiary and sterically hindered amine aqueous solutions at various conditions was studied. in the present work, the modified kent-eisenberg (m-ke), the extended debye-hückel (e-dh) and the pitzer models were employed to study the solubility of co2 in amine aqueous solutions. two explicit equations are presented to evaluate the concentration of h...

reducing the bacterial level on skin, it does not eliminate all resident bacterial microflora on the skin, thus one-way pressure for the proliferation of a competing organism does not exist. Furthermore, many experts agree that normal dry skin is not a hospitable environment for the survival of gram-negative species. Long-term studies m e a s u r i n g t h e c o n s e q u e n c e s of exposure ...

Prior to European settlement in western North America, bighorn sheep (Ovis canadensis) were more widespread and abundant than they are today (Buechner 1960). The species arrived via the Bering land bridge approximately 70-100,000 years before the present (YBP) (Kurten and Anderson 1980) and slowly spread to occupy most mountainous regions of western North America from southern British Columbia ...

It is generally accepted that the frequency of placenta praevia is higher among multigravidae than among primigravidae. This observation has prompted the suggestion that low implantation of the ovum is a result of functional or structural changes in the uterus resulting from repeated pregnancies (Solomons and Canter, 1932; Davis and Campbell, 1946; Shaw, 1947; Findley, 1951). It is possible, ho...
