Water is the first and foremost limiting factor for agricultural production, and undoubtedly, water crisis is considered as one of the international challenges for governments and human societies. Given that virtual water was first used as a way to tackle water scarcity in countries with limited water resources, so that countries with low water should import food from abundant countries...

The epidemiology of dental fluorosis derives from surveys carried out in recent years, as a result of a better comprehension of metabolic aspects of fluoride in the human organism and oral health concerns. This reflection aims at presenting studies carried out on fluorosis between 1993 and 2006. The period of 1993-2004 delimits the interval between the 2nd and the 3rd National Conferences on Or...

Compared to other population groups in the United States, caries (tooth decay) is a disproportionately prevalent disease among Latino populations, especially among low-income and rural sub-groups and children under five years of age. Fluoride is a primary preventive for caries. While water fluoridation is a major and effective public health means for delivering fluoride on a mass scale, it does...

609 samples of drinking water collected from scattered sources from the eight districts of Kandy, Matale, Kalutara, Anuradhapura, Polonnaruwa, Colombo,. Puttalam and Gampaha were analysed for iodide content using the Orion electrode method. The median iodide content of all districts except Gampaha were above 10 u g / 1 , with Anuradhapura showing the highest content. Districts with low prevalen...

The overall reduction in caries prevalence and severity in the United States over recent decades is largely due to widespread exposure to fluoride, most notably from the fluoridation of drinking waters. Despite this overall reduction, however, caries distribution today remains skewed, with the poor and deprived carrying a disproportionate share of the disease burden. Dental caries, like many ot...

in order to study the sensitivity of vegetative growth to water deficit stress of a late-maturing peach (prunus persica l. cv. elberta) under orchard conditions, an experiment was conducted as randomized complete-block design with three treatments and four repetitions in shahdiran commercial orchard in mashhad during 2011. three irrigation treatments including 360 (low stress), 180 (moderate st...

When rapidly cooled, a liquid undergoes dynamic arrest, forming an amorphous solid commonly called glass. Amorphous solids can also be created by different routes, for example by destabilizing the crystal structure at low temperature by applying pressure or intense radiation, or by depositing gas molecules on very cold substrates. Even though the resulting materials encode information about the...
