production of thin steel strips with 0.18-0.26 mm thickness is about 0.75 of annual production of the two stand reversing cold mill, while its efficiency is 60%. this is due to the fact that after montaging the grinded work rolls, rolling thin steel strips (with thicknesses less than 0.18 millimeters) is unavailable. initially, unsuitable surface roughness, the friction between rolls and the st...

T he selection of an appropriate occlusal registration strip enables the dentist to work with precision and provides valuable information on occlusion. There are significant differences in the thickness, strength, and plastic deformation of the various articulating papers and occlusal registration strips. The patient’s perception of occlusal thickness ranges from 12.5 to 100 prn.“‘j The thickne...

Roll-to-roll (R2R) slot-die coating systems are mostly devoted to the mass manufacture of printed electronics. This study examined the correlation among the operating conditions, thickness, and width of the patterned strip fabricated by the R2R slot-die system. A full factorial experiment was conducted to screen for effective parameters. The velocity of a moving substrate was found to be the mo...

Freeze-drying and gamma irradiation are the techniques widely use in tissue banking for preservation and sterilization of tissue grafts respectively. However, the effect of these techniques on biomechanical properties of bovine pericardium is poorly known. A total of 300 strips of bovine pericardium each measured 4 cm 1 cm were used in this study to evaluate the effect of freeze-drying on biome...

OBJECTIVES Evaluate the thickness and the marking quality of different occlusal contact registration strips (OCRS) and a possible correlation between them. MATERIAL AND METHODS The following OCRS were selected: Accufilm II, BK20, BK21, BK22, BK23, BK28, and BK31. The thickness was measured in three points of the OCRS with an electronic measuring device (TESA), and the mean was calculated. To ...

The development of value added composite products from bamboo with the application of gluing technology can play a vital role in economic development and also in forest resource conservation of any country. In this study, the gluability of Bambusa balcooa and Bambusa vulgaris, two locally grown bamboo species of Bangladesh was assessed. As the culm wall thickness of bamboos decreases from botto...

in order to investigate the effect of temperature and time of blanching process on the generation and extraction of reducing sugars and kinetics of color changes during blanching, the potato strips packaged in the polyethylene (hdpe with 10 micron thickness) film or without polyethylene packaging, were immersed in distilled water at temperature range of 50, 60, 70, 80 and 90 ºc for 120 minutes....
