Laboratory animal workers are at risk of developing allergic symptoms, of which asthmatic symptoms are the most severe. The aim was to study the relationship between allergic symptoms due to working with rats and variability and changes in peak expiratory flow (PEF). Several indices were used on the basis of the amplitude of the PEF or the differences in PEF between days with and without exposu...

This work develops a statistical model to assess the frost risk in Rafsanjan, one of the largest pistachio production regions in the world. These models can be used to estimate the probability that a frost happens in a given time-period during the year; a frost happens after 10 warm days in the growing season. These probability estimates then can be used for: (1) assessing the agroclimate risk ...

We analyze mobility in urban Mexico between three labor market states: working in the formal sector, working in the informal sector, and not working. We use a dynamic multinomial logit panel data model with random effects, explaining the labor market state of each individual during each time period. The data is drawn from Mexico’s Urban Employment Survey, a quarterly household survey for urban ...

Indonesia is currently actively developing infrastructure to improve the economy and welfare of itspeople. One developments undertaken by government road pavement. CV.X company that won asphalt project tender with a contract value IDR 4.046.873.346 must complete it within 114 days. During process working on project, there were indications possible delays in completion. So this study aims perfor...

PURPOSE (i) To evaluate firefighters' pre- and post-shift hydration status across two shifts of wildfire suppression work in hot weather conditions. (ii) To document firefighters' fluid intake during and between two shifts of wildfire suppression work. (iii) To compare firefighters' heart rate, activity, rating of perceived exertion (RPE), and core temperature across the two consecutive shifts ...

abstract seafood is valuable protein sources for human being and acts important role in a healthy diet. due to probability of fish contamination, from catch time to consume time with different microorganisms, there’s different technics to prevent fish spoilage. the present study purposed to investigate the effect of encapsulated thyme (zataria multiflora boiss) extract and chitosan to inhibit l...

in the present study, the mechanical behavior of aa5052 aluminum alloy during cold deformation and subsequent isothermal annealing in a temperature range of 225-300oc was investigated using the uniaxial tensile test data. it is found that by increasing the annealing time and temperature the material yield strength is decreased. the microstructural investigations of the annealed samples show tha...

although investigating the factors that influence test scores is important, a majority of stakeholders show a paucity of attention towards individual learner differences due to having large classes of l2 learners. this study sought to explore the possible effect of working memory and cognitive style on l2 learners’ metaphorical test performance. the study was conducted in 2 phases. the first ph...
