background: in the refractory brick manufacturing industry, because of the high risks associated with the level of dust in the factory environment and thermal stress, a precise identification of industrial hazards is required as a part of safety analysis. the aim of this study was to introduce a preventive approach to risk identification and assessment in the refractory brick production line.  ...

In contrast to the approaches to resource management and preservation of the past decade, a new perspective on environmental problems is emerging. Six major trends in scientific thinking are (i) increased efforts to examine environments In holistic frameworks, (ii) greater attention to life support systems, (iii) enlarged canvass of the range of choices in resource management, (iv) refinement i...

built environment does not “simply appear overnight, like a movie-set springing up on a vacant lot, but has to be produced”.thus, the first point in dealing with such an environment is considered to be the tracing of time in the evaluation of the city and keeping in mind that the whole is more than its parts. the last point becomes naturally understood when the process of city building is p...

background and purpose: there is an increasing interest and concern regarding the role of learning environment in undergraduate medical education in recent years. educational environment is one of the most important factors determining the success of an effective curriculum. the quality of educational environment has been identified to be crucial for effective learning.we compared the perceptio...

linear green infrastructures along rivers and canals serve different functions: green corridors, or ecological network, maintain biological diversity, improve water quality, and provide areas for fauna and flora to grow and thrive. greenways connect people with landscape resources and serve as recreational areasthat are easy to use and accessible to the greatest number of potential human users....

Subterranean specialization is often accompanied by dramatic phenotypic changes epitomized regressive evolution (e.g. loss or reduction of eyes and pigmentation). Nevertheless, the genetic underpinnings underlying these have been largely unexplored. The beetle tribes Leptodirini (Leiodidae), Hydroporini Bidessini (Dytiscidae) represent ideal systems for exploring genomic basis adaptation to lif...
