Estimation of exposure-response relations from epidemiological data is complicated by the fact that exposures usually vary in intensity over time. Cumulative exposure indices, which do not separate the effects of intensity and duration, are commonly used to circumvent this problem. In this paper the estimation of relative risk for specific ranges of exposure intensity from such data is consider...

Sanitaryware is the generic term used to describe items which traditionally were made from pottery. i.e. toilets, washbasins, pedestals, bidet, urinals, sinks, bathtubs installed within a bathroom or washroom. products are primarily of clay, kaolin, feldspar and quartz but they may also include small quantities other raw materials. Its high gloss, stain resistant surface ideal for use in both b...

Industrial processes and the building sector (e.g., for space water heating) are responsible majority of total energy consumed heat. Although fossil fuels remain to dominate heating sector, renewable technologies have been lately widely deployed. Thermochemical storage (TES) can be a promising advanced technology in addressing mismatch between supplies end-user’s demand. In this paper, novel <e...

Seedlings of maize (Zea mays L. cv WF9 x Mo 17) were grown in vermiculite at various water potentials. The primary root continued slow rates of elongation at water potentials which completely inhibited shoot growth. To gain an increased understanding of the root growth response, we examined the spatial distribution of growth at various water potentials. Time lapse photography of the growth of m...

abstract the association between neotyphodium spp. endophytes and cool-season grasses, particularly tall fescue (festuca arundinacea, schreb), represents a widespread type of mutualism in nature. numerous researches were performed about positive effect of symbiosis on plant resistance to different stresses but the role of symbiosis on nutrients uptake particularly potassium uptake and k-bearing...

BACKGROUND Community exposure to asbestos from contaminated vermiculite ore from Libby, Montana, occurred in many processing sites in the United States, including a densely populated urban residential neighborhood of Minneapolis, Minnesota. OBJECTIVE We examined exposed community residents who never worked at the plant or never lived with a plant worker for radiographic evidence of lung chang...

Urease is one of the most important enzymes in nitrogen cycle. The clay particles (with high surface area) play an important role in the stability of these protein compounds (enzymes) against various environmental factors. In order to examine the interactions between urease with sepiolite and vermiculite, three in vitro experiments were conducted separately in a completely randomized design. Tw...
