OBJECTIVES Although respiratory exposures have been the primary concern with isocyanates, skin exposure also can occur and may contribute to sensitization and asthma. Methodologies to assess isocyanate skin exposure in the workplace are limited and skin exposure data scarce. The goals of this study were (i) to evaluate and validate the isocyanate colorimetric indicators against a quantitative a...

this paper presents a mathematical model for a flow shop scheduling problem consisting of m machine and n jobs with fuzzy processing times that can be estimated as independent stochastic or fuzzy numbers. in the traditional flow shop scheduling problem, the typical objective is to minimize the makespan). however,, two significant criteria for each schedule in stochastic models are: expectable m...

The authors deal with the optimization of production planning in the mixed-model assembly production. Modern paint shops are highly complex facilities with a multitude of interdependent process steps. In order to describe the occurring throughput and processing times, the behavior of these times is of great interest for production planning, a modeling of the paint shop is necessary. The disrupt...

This is a summary of the journal article (Malapert et al. 2012) published by Journal on Computing entitled “An Optimal Constraint Programming Approach to the Open-Shop Problem”. The article presents an optimal constraint programming approach for the Open-Shop scheduling problem, which integrates recent constraint propagation and branching techniques with new upper bound heuristics. Randomized r...

Washington State birth certificates were examined for associations between adverse pregnancy outcomes and paternal employment in solvent exposed occupations. Four cohorts defined by live, singleton births to fathers usually employed as auto body shop workers, painters (construction and maintenance), printers, or fibreglass workers were compared retrospectively with both a systematically selecte...

In the marketing strategy, uses promotion through digital which aims to develop a wider selling market concepts, also this concept will make it easier process spending. With this, output results implementation can be accepted by Motor, such as...

There have been several techniques to repair the medial meniscus posterior root tears (MMPRTs) with the goal of restoring the anatomic and firm fixation of the meniscal root to bone. Many anatomic studies about the menisci also have been developed, so a better understanding of the anatomy could help surgeons perform correct fixation of the MMPRTs. The meniscal roots have ligament-like structure...

PURPOSE To examine the association of personal values, the built environment, and auto availability with walking for transportation. SETTING Participants were drawn from 11 U.S. metropolitan areas with good transit services. SUBJECTS 865 adults who had recently made or were contemplating making a residential move. MEASURES Respondents reported if walking was their primary mode for nine tr...
