observed Changes Surface Globally, as well as in the tropics, the temperature of the air near the Earth’s surface has increased since 1958, with a greater rate of increase since 1979. All three surface temperature data sets are consistent in these conclusions. • Globally, temperature increased at a rate of about 0.12oC per decade since 1958, and about 0.16oC per decade since 1979. • In the trop...

Kinetic studies of alcohol dehydrogenase prepared from horse liver by different methods have given different results (Theorell, Nygaard & Bonnichsen, 1955; Dalziel, 1958; Theorell, 1958; K. Dalziel, unpublished work, 1957). The most active crystalline preparations have been obtained by a modification of earlier methods (Bonnichsen, 1950; Bonnichsen & Brink, 1955) in which the principal new feat...

The analytical electrophoretic pattern of the buffer-soluble proteins extracted from bacterial cells is both characteristic and descriptive of the organism (Hess et al., 1957; Wagman et al., 1958; Rodenberg, 1958). Further, a relatively large fraction of the material of the cell can be studied by the electrophoretic method. Hess et al. (1957) using successive extractive procedures on three stra...

to identify the horticultural of plant parasitic nematodes in northern khorasan province, 170 soil and plant root samples were collected during different seasons of years 2009 and 2010. nematodes were extracted through centrifugal-flotation method, specimens then being fixed according to modified seinhorst method and transferred to glycerin before making measurements (de grisse, 1969). througho...
