1. A method is described for measuring the swelling pressure of solid gelatin. 2. It was found that this pressure increases rapidly between 15 degrees and 37 degrees C., and that the percentage change is nearly independent of the concentration of gelatin. 3. It is suggested that this pressure is due to the osmotic pressure of a soluble constituent of the gelatin held in the network of insoluble...

The surface V3 of the denuded corneal stroma was separated into the anterior and posterior segments; the swelling ratio of each was compared under zero pressure. In the rabbit, cat, and bovine corneas, the anterior segment was less hydrophilic than the posterior one, in both the central and peripheral regions. In the rabbit cornea, the swelling ratio of the posterior segment was significantly l...

Papilloedema is a term that describes a non-inflammatory swelling of the optic nerve head that is now restricted only to patients with increased intracranial pressure. It thus implies a clinical diagnosis in addition to a physical finding while the term optic disc swelling is employed for the mere clinical description. We describe a haemodialysis patient who developed sudden onset of optic disc...

CO2 geosequestration is currently considered to be the most effective and economical method to dispose of artificial greenhouse gases. There are a large number of coal mines that will be scrapped, and some of them are located in deep formations in China. CO2 storage in abandoned coal mines will be a potential option for greenhouse gas disposal. However, CO2 trapping in deep coal pillars would i...

Abstraet-The limitations of existing methods for the prediction of swelling behavior of compacted softs are examined. Both the purely theoretical approach and the purely empirical approach are found to be inadequate. The present study is based on a semi-empirical approach in which a model of swelling behavior is developed leading to equations relating swelling potential or swelling pressure of ...

The purpose of this study was to investigate deltoid compartment pressures during arthroscopic rotator cuff repair using modern pressure pumps to achieve visualization. Twelve patients undergoing arthroscopic rotator cuff repairs were monitored for deltoid compartment pressure changes intraoperatively. Pre-, intra-, and postoperative intramuscular pressures were recorded. All patients demonstra...
