Our aim was to characterize the magnetic resonance (MR) imaging features of canine disc extrusion accompanied by epidural hemorrhage or inflammation. We correlated the imaging characteristics of this type of disc extrusion in 46 dogs and compared these features with clinical signs and pathologic findings. Data from 50 control dogs with MR imaging features of a disc extrusion with no associated ...

Interest in brines in extreme and cold environments has recently increased after they have been found on Mars. Those brines can be potential new subsurface habitats for peculiar ecosystems. In the McMurdo Dry Valleys of the Antarctic, the best analogue for Mars conditions, only a few cases of brines have been identified in some perennially frozen lakes and in one case in an underground aquifer....

This study investigated the chemical grafting of a single-layer poly(vinyl alcohol) (PVOH) film. The effect of the grafting parameters (grafting time, grafting temperature, and concentration of fatty acid chloride) on the hydrophobicity of the film surface and the film solubility were evaluated. The PVOH substrate film (cold-water soluble at 20°C) was manufactured by flat extrusion and had a th...

The tensile properties of Mg-3%Al nanocrystalline alloys were investigated at different test environment. Bulk nanocrystalline samples of these alloy was successfully prepared by mechanical alloying (MA) followed by cold compaction, sintering, and hot extrusion process. The crystal size of the consolidated milled sample was calculated by X-Ray line profile analysis. The deformation mechanism an...

A method for the extrusion of arbitrary polygon meshes is introduced. This method can be applied to model a large class of complex 3-D closed surfaces. It consists of defining a (typically small) set of connected polygons in 3-D that form a skeleton of the final object, and assigning extrusion distances to all polygons. Both sides of a polygon may have different extrusion distances. An automati...

E ARLIER investigations ' 2 with mammalian heart muscle have shown that the resting potential drops only slightly when the temperature is lowered from 37 to 20 C , but decreases considerably upon further cooling. Coraboeuf and Weidmann suggested 3 possible explanations for the depolarization in the cold: (1) a rise of the Na permeability relative to the K and Cl permeabilities of the fiber memb...

The recrystallisation behaviour of PM2000 oxide dispersion strengthened ferritic alloy has been investigated for samples which were cold deformed after extrusion. The evolution of the recrystallisation temperature TR, defined as the minimum temperature at which the sample begins to recrystallise, has been studied in detail as a function of the level of deformation. The microstructure was charac...

The present study pertains to the development of a gluten free ready to serve buckwheat nutritious powdered product. The process consists of dehulling and extrusion of dehulled buckwheat from which ready to serve buckwheat flour is obtained. The ready to serve flour is further utilized for product development by mixing it with skimmed milk powder, sugar and food grade additives. The developed p...

OBJECTIVES Meniscal extrusion is often present in knees with OA, and has been associated with cartilage changes. It is unknown whether meniscal extrusion is related to subchondral bone. The aim of the study was to examine the relationship between meniscal extrusion and knee cartilage and subchondral bone, and also changes in these structures over 2 years in a cohort with mild to moderate knee O...
