The aim of this study was to compare polymerization lamps of various technologies (halogen, high performance halogen, xenon, i.e. plasma arc, as well as diode lamps) to determine the degree of polymerization of composite probes using Fourier-transform infrared (FTIR) spectroscopy. To observe the light-induced curing reaction under a bracket, an attenuated total reflection (ATR)-FTIR was used. T...

when geotechnical engineers are faced with cohesive clayey soils, the engineering properties of those soils may need to be improved to make them suitable for construction. the aim of this paper is to study the effect of using lime, natural pozzolana or a combination of both on the geotechnical characteristics of two cohesive soils. lime or natural pozzolana were added to these soils at ranges o...

methods thirty healthy female volunteers aged between 18 and 30 years were treated by a 15-minute cryotherapy (6 ± 1°c). the subject's skin temperature over antromedial aspect of dominant ankle was measured by the mayomed device before, immediate and 15 minutes after water immersion. ankle jps was tested trough the pedal goniometer at 3 stages similar to the skin temperature. anova (α = 0.05) w...

Abstract Photopolymerization of hydrogels films has gained interest in many biomedical and industrial fields. Hydrogel micro-patterns fabricated directly on a device are used as filtering barriers, however, due to weak mechanical properties, these parts require stable support but deposition hydrogel non-polymerized state brings risk sinking inside the structure. These limitations can be overcom...

Solidifying shield muck with calcium carbide slag and fly ash as curing agents was proposed a highly efficient method for reusing waste muck. The compaction test, unconfined compression dry–wet cycle test were used to evaluate the compressive strength, water immersion stability, durability of cured soil. stress–strain curve microscopic employed analyze damage law, mineral composition, morpholog...
