A series of field evaluations was performed at three freeway interchange ramps in Michigan that possessed significant horizontal curvature to assess the impacts a dynamic speed feedback sign (DSFS) on driver selection and brake response while approaching entering ramp curve. DSFS with 15 in. full-matrix display temporarily installed each exit locations. The programmed same message location, whi...

karkhe watershed (kw) with more than 5 million hectares recently encountered many problems in the natural, social and man-made habitats. unsuitable use of land, soil erosion and lack of rainfall are the most destructive factors in this watershed affecting the whole region fundamentally. as expected, these problems have caused a considerable fall in biodiversity in fauna and flora, a decrease in...

nitrate is an anion of major importance particularly in biological areas. excessive amounts in water supplies indicate pollution from sewage or agricultural effluents. the effects of excessive quantities of nitrate in water are well known. in this research structural modification of natural clinoptilolite by isomorphic substitution was performed. isomorphously substituted zeolite was prepared u...

Currently, expressways encourage the use of interchange design methods in layout mode to improve safety expressway operation order relieve road transportation pressure and strengthen prevention traffic accidents. The advantages characteristics method are more obvious have important application value when compared other methods. This paper mainly studies analyzes on major challenges interchanges...

ULLER'S original discovery that ionizing radiations are capable of 141 breaking the chromosome thread was based on investigations carried out with Drosophila melanogaster. But in spite of the numerous studies which have been undertaken using this animal, comparatively little progress has been made in the last twenty years in determining the precise manner in which these breaks are formed and th...

Abstract Recently, the Gravitational Decoupling through Minimal Geometric Deformation was applied to study a mixture of spherically symmetric internal solution Einstein gravitational equations with polytropic fluid, giving interesting results energetic interchanges in special case Tolman IV solution. In this work, we extend these newly introduced methods VII space-times that are currently consi...
