During the summer of 2015, India was hit by a scorching heat wave that melted pavements in Delhi and caused thousands of deaths, mainly among the most marginalized populations. One such group facing growing heat risks from both occupational and meteorological causes are migrant brick kiln workers. This study evaluates both current heat risks and the potential future impacts of heat caused by cl...
Background: In brick kiln and construction industry the exposure to carbon monoxide and silica dust is the most common occupational hazard to the workers in these industries. A study on occupational health hazards of working women in these two unorganized sectors was undertaken by Lokmanya Medical Research Centre. Objectives: To study the effect of work site environment on the health of the wom...
An interesting subclass of Noun-noun combinations in English can take two meanings depending on whether the first or second word is stressed in speech. A BRICK factory is one that makes bricks, whereas a brick FACTORY is one made of brick. An explanation is offered in terms of a bias for nouns from particular ontological categories to trigger particular semantic interpretations for a combinatio...
The four lectures follow closely a textbook on Potential Theory in the Complex Plane by T. Ransford, apart from material on harmonic measure which has been borrowed from a lecture course Introduction to Potential Theory with Applications, by C. Kuehn. The material in lecture 5 is borrowed from a survey Logarithmic Potential Theory with Applications to Approximation Theory by E. B. Saff (E-print...
Introduction: Replacingfuel oil with natural gas in brick kilns is one of the effective ways to reduce air pollution as well as the cost of the furnaces maintenance. The aim of this study isto estimate reduction of air pollutants resulting from brick kilns functioning with natural gasin Yazdprovince. Methods: In this descriptive-survey research, we estimated consumption of the fuel oil in the ...
Introduction: Exposure to dust is an essential factor in the brick production industry. Determining the mortality rate from silicosis and lung cancer is very important in exposure to crystalline silica dust. Therefore, this study was conducted to risk assessment of workers in machine factories and traditional brick production workshops. Materials and Methods: This cross-sectional study was con...

Abstract—Coal fly ash, an industrial by product of coal combustion thermal power plants is considered as a hazardous material and its improper disposal has become an environmental issue. On the other hand, manufacturing conventional clay bricks involves on consumption of large amount of clay and leads substantial depletion of topsoil. This paper unveils the possibility of using fly ash as a par...
This study analyzed the last 20 years` data available on power plant coal ashes used in clay brick production. The statistical analysis has been carried out for a total of 302 cases based relevant parameters reported literature. chemical composition clays and ashes, percentage incorporation maximum particle size ash, fired samples, peak firing temperature, corresponding soaking time were select...
