Due to increased government regulations on environment, health, and safety, the cost of on-site bridge painting has quadrupled over the past several years. The construction industry faces a great challenge in how to control the increased costs of bridge painting and meet the regulations at the same time. A possible solution to address this challenge is to develop a robotic bridge painting syste...
From the middle of the Safavid era, with the expansion of relations with the West, European landscapes were used in various ways in the composition of paintings called “FARANGI-SAZI”. In this article, by adopting a hermeneutic approach, the epistemological context necessary for the emergence of “landscape painting” as an independent genre in European painting has been studied and then the trans...
Shipyard painting is most often viewed as pure ship construction operations, where the painting of the hull, deck, superstructure, and cargo spaces makes up the total effort and cost. This view may be justified when analyzing various trade production costs as parts of the total ship cost. However, parts preparation and painting costs are significant when looked at in summary as a new constructi...
Commercially available controls for reducing worker exposure to paint overspray were evaluated in six autobody shops and a spray-painting equipment manufacturer's test facility. Engineering control measures included spray-painting booths, vehicle preparation stations, and spray-painting guns. The controls were evaluated by measuring particulate overspray concentrations in the worker's breathing...
Statement of Problem: The use of dentine bondings on enamel and dentin in total etch protocols has recently become popular. Unfilled resin is hydrophobic and dentin bonding is hydrophilic in nature. This chemical difference could be effective in enamel bonding process. Purpose: The aim of this study was to compare the shear bond strength of unfilled resin to dry enamel and dentin bonding to dry...
Research for creating impressive images like paintings has attained more and more importance because of the recent growth in processing images. Among many painting styles, watercolor style gives a strong impression because of its thin colors and its soft appearance. This paper proposes a method to create watercolor style images from input images, for instance photographs. In contrast with the p...
The occlusal morphology of the teeth is mostly determined by the enamel-dentine junction morphology; the enamel-dentine junction plays the role of a primer and conditions the formation of the occlusal enamel reliefs. However, the accretion of the enamel cap yields thickness variations that alter the morphology and the topography of the enamel-dentine junction (i.e., the differential deposition ...
Introduction: Adverse effects of volatile organic compounds (VOCs) including general and specific effects like carcinogenic of benzene are well known. The aim of this study was to evaluate occupational exposure to BTEX compounds in the painting unit of an automotive industry and subsequently health risk assessment of exposure to these compounds. Material and Method: This cross-sectional stud...
Young children are at greatest risk of exposure to lead and its effects. Although lead is one of the most widely used elements with known health hazard, there is little data on the blood lead level (BLL) of children in the Kathmandu Valley. Thus, this study aimed to assess factors associated with high BLL in children who were 6-36 months of age and resided in the Kathmandu Valley. In this hospi...
The aim of this study is to assess the quantitative ions changes in enamel occlusal surfaces affected by white-spot and brown-spot dental caries. Energy dispersive X-rays analysis (EDX) has been used for qualitative and quantitative chemical analysis of 30 enamel samples (10 sound enamel samples, 10 white-spot enamel samples, 10 brown-spot enamel samples). For samples with white-spot and brown-...
