UNLABELLED To our knowledge comparative studies of intracranial pressure (ICP) and degree of cerebral swelling during craniotomy for supratentorial or infratentorial space occupying lesion in children are not available. In this prospective study subdural ICP, cerebral perfusion pressure (CPP), dural tension, and the degree of cerebral swelling were analysed in supine and prone positioned childr...

It has been assumed that gelatin consists of a network of an insoluble material enclosing a solution of a more soluble material. The swelling of gelatin is therefore primarily an osmotic phenomena in that the water tends to diffuse in owing to the osmotic pressure of the soluble material. This osmotic pressure is opposed by the elasticity of the insoluble constituent, and equilibrium results wh...

Swelling of the optic disc may result from inflammation, infiltration, nerve compression or ischaemia, as well increased intracranial pressure. It can be imitated by local structural features leading to pseudopapilloedema. Disease entities swelling take different courses in paediatric population compared adult population. Investigations used confirm diagnosis include optical coherence tomograph...

The pathophysiology of acute mountain sickness and high-altitude cerebral edema, the cerebral forms of high-altitude illness, remain uncertain and controversial. Persistently elevated or pathological fluctuations in intracranial pressure are thought to cause symptoms similar to those reported by individuals suffering cerebral forms of high-altitude illness. This review first focuses on the basi...

Coal swelling in the presence of water as well as CO2 is a well-known phenomenon, and these may affect the permeability of coal. Quantifying swelling effects is becoming an important issue to verify the suitability of particular coal seams for CO2-enhanced coal bed methane recovery projects. In this report, coal swelling experiments using a visualization method in the CO2 supercritical conditio...

The flow through a porous medium strongly depends on the boundary conditions, very often assumed to be static. Here, we consider changes in due swelling and erosion extend existing Lattice-Boltzmann models include both. We study two conditions: constant pressure drop rate. For rate, steady state solely dynamics while for it also timescale of swelling. analyze competition between identify transi...

The mechanisms underlying the success of UVA–riboflavin collagen cross-linking (CXL) to arrest or allay corneal ectasia are not well understood. One observation that may shed light on the underpinnings of CXL: the cornea thins after the procedure for at least several months. Thinning produces a more compact and stiffer tissue. Normally, corneal thickness is controlled by endothelial active tran...

A 44 year old man presented with a 15-day history of painful swelling of right middle finger, which was also red, warm, and tender. A tooth paste like, chalky substance was expressible on pressure from the swelling. The patient reported that he had occasional episodes of joint pains involving both small and large joints of the extremities. He denied a history of medication intake and past histo...

in this research the mechanical behavior of an expansive soil (with different pore fluid) was investigated under the constant and variable temperature through experimental tests. the soil samples with different pore fluid (distilled water, nacl and cacl2 with concentration of 250 gr/lit) were prepared by static compaction method. experimental testes were conducted in two modified odometer under...
