Use of variable Pressure SEMs is spreading among electron microscopists The variable Pressure SEM does not necessarily require specimen Preparation such as fixation, dehydration, coating, etc which have been required for conventional scanning electron microscopy. The variable Pressure SEM allows operating Pressure of 1˜270 Pa in specimen chamber It does not allow microscopy of water-containing specimens under a saturated vapor Pressure of water. Therefore, it may cause shrink or deformation of water-containing soft specimens such as plant cells due to evaporation of water. A solution to this Problem is to lower the specimen temperature and maintain saturated vapor Pressures of water at low as shown in Fig. 1 On this technique, there is a Published report of experiment to have sufficient signal to noise ratio for scondary electron imaging at a relatively long working distance using an environmental SEM. We report here a new low temperature microscopy of soft Plant cells using a variable Pressure SEM (Hitachi S-225ON).

AbstractPopulations of rock hyraxes (Procavia capensis) increasingly occur in urbanizing areas of the Palestinian West Bank, and throughout the Middle East, in part due to construction methods that create rock piles that shelter hyraxes. We quantified activity densities of the hyraxes, environmental variables, and plant cover at four sites that differ in urbanization. The highest numbers occurred in the most urban site and peaked in June and October, with hyraxes traveling farther distances from their dens late in the season (October). Sites with higher activity densities of hyraxes had higher vapor pressures, signifying more mesic conditions. Thus, urbanization aids the expansion of hyraxes.
