Recently, some fluid or pour resins have been introduced to simplify the processing of dentures. However, because of the presence of relatively high residual monomer, the mechanical properties of these resins are inferior to those of heat cured resins.1,2) The purpose of the present investigation is to measure the quantities of residual monomer and to investigate the effect of the residual mono...

X-ray diffraction, optical microscopy and microhardness testing have been used to study properties which develop in micro-cut AISI 1045 steel. The influence of the ploughing effect on residual stresses, surface deformation and work hardening, and the tool quality were investigated. Tensile residual stresses, caused by the heat generated in the material during the cutting process, were observed ...

After undergoing a manufacturing process, materials may exhibit internal stresses referred to as residual stresses. In steel-composite hybrid structures, residual stresses are typically formed due to the unequal thermal behaviour of the steel and composite. Thus, knowledge of the residual stress state is important in the assessment of the external-internal loading in steel-composite hybrid stru...

In order to achieve integrated condition in the girth welding of high pressure natural gas transmission pipelines, the weld zones and its surrounding area should have good mechanical properties. Residual stresses are an important defect especially in the girth welding of the pipeline. In this study, two API X70 steel pipes (with spiral seam weld) of 56 inches outside diameter and 0.780 inch wal...

Residual Wage Inequality in Urban China, 1995-2007 We use three waves of urban household survey data from 1995 to 2007 to investigate the trends of residual inequality and its determinants. First, we describe the change of overall and residual wage inequality over time. One important new pattern is that the rise in both the overall and residual inequality mainly happened at the upper half of th...

The compositing technique used to derive global vegetation index (NDVI) from the NOAA-AVHRR radiances, reduces the residual effect of water vapor and aerosol on the NDVI . The reduction in the atmospheric effect is shown using a comprehensive measured data set for desert conditions, and a simulation for grass with continental aerosol. A statistical analysis of the probability of occurrence of a...

genetic parameters were estimated for somatic cell score (scs) in dairy cattle of iran using test day records. the records of first lactation were extracted from the database of national animal breeding center for cows calved between 2001 and 2010. data included 222923 test-day records, obtained from 29668 animals distributed in 100 different herds. estimates were carried out through gibbs samp...
