nylon-mesh bag or a plastic tissue-basket. Dehydration with alcohol and celloidin embedding: Dehydration
Precise knowledge of various ganglia is very important for a' thorough understanding of clinical medicine. Details of these ganglia, however, have not been included in textbook descriptions. We conducted our research to bring precise figures to light. We selected several ganglia as follows: the GG, which is the site of nerve cell bodies for the special sense of taste; the SG, which supplies pre...
متن کاملDirect observation of t-butyl alcohol frozen and sublimated samples using low-vacuum scanning electron microscopy.
Frozen biological specimens in t-butyl alcohol were examined under a low-vacuum environment in a "wet SEM" or "variable pressure SEM (scanning electron microscope)" equipped with a cooling stage and highly sensitive backscattered detector of the YAG type. After fixation with glutaraldehyde and osmium tetroxide, rat tissue blocks (tracheae and kidneys), and cultured human carcinoma cells were de...
متن کاملIntramolecular crosslinking of poly(vinyl alcohol)
Poly(vinyl alcohol) is crosslinked in dilute solution (c = 0.1 wt%) with glutaraldehyde. The reaction product is characterized by viscometry and gel permeation chromatography (g.p.c.). The intrinsic viscosity decreases with increasing degree of crosslinking and does not depend on temperature. G.p.c. reveals that the reaction product is not homogeneous, but consists of a mixture of particles wit...
متن کاملMass Transfer During the Pre-Usage Dehydration of Polyvinyl Alcohol Hydrogel Wound Dressings
Nowadays, hydrogels are widely used as wound dressings in biomedical applications. Similar to other types of the moist (wet) wound dressings, it is necessary to have sufficient information about their dehydration kinetics during the pre-usage period (e.g. storage duration) and also the wound healing process. In this work, hydrogel wound dressings based on polyvinyl alcohol were prepared by...
متن کاملEFFECT OF OPERATING CONDITIONS ON THE DEHYDRATION OF TOLUENE BY PERVAPORATION USING A POLYVINYL ALCOHOL MEMBRANE
The effects of operating parameters such as feed temperature and permeate-side pressure on the performance of a commercial PVA membrane in the dehydration of toluene by a pervaporation (PV) membrane system is studied in the present work. The results obtained indicate that increasing temperature in the range of 40 to 70 °C and reducing permeate pressure in the range of 1 to 10 mmHg increase memb...
