Cooling times for various autoclave loads were recorded using thermocouples. Loads which may be encountered during normal laboratory working require between 17 and 174 minutes to cool to 100 degrees, C and up to 260 minutes to cool to 95 degrees C. Such long cooling times had an adverse effect on nutritive properties of bacteriological culture medium. Observations are made on some factors which...

Abnormalities in intestinal function associated with changes in meconium, which are usually discussed under the heading of meconium ileus, are responsible for many deaths in the newborn period. Disorders produced by meconium would seem to be largely due to intestinal obstruction due to the meconium being unusually tenacious and firm. The basic constituents of normal meconium have been known for...

Coastal waters represent the commingling of offshore marine and terrestrial surface source waters and therefore are naturally complex and variable. Our long term goal is to establish observational and modeling approaches to predict sources and scales of variability in the source waters, particularly those related to land use activities in upstream watersheds, from observations and measurements ...

In this paper, we describe an innovative project where Web technologies are exploited to foster science learning in an integrated but mobile smart learning environment. Contextawareness is considered a crucial skill in science learning, therefore we imagined a solution to train students for context awareness by illustrating context gaps based on on-site observations and measurements. A componen...

One the most cited papers in astronomy is Ken Freeman's 1970 paper on exponential disks in galaxies. In this contribution I review what has been done in this area since then and what we can infer about systematic properties of disks in galaxies from surface photometry, HI synthesis observations and measurements of stellar kinematics. Most disks have radial truncations at 3.6 ± 0.6 radial scalel...
