APrIl 2017 IZA DP No. 10697 The Effects of Physical Restructuring on the Socioeconomic Status of Neighborhoods: Selective Migration and Upgrading In the last few decades, urban restructuring programs have been implemented in many Western European cities with the main goal of combating a variety of socioeconomic problems in deprived neighborhoods. The main instrument of restructuring has been ho...

Air quality in demolition practices has seldom been evaluated in Iran. Accordingly, we evaluated asbestos exposure among Tehran construction workers during the demolition of old houses. To identify possible sources of asbestos exposure, including thermal insulations, chimney pipes and cement sheets, were all sampled. This study also were taken the personal air samples to evaluate any asbestos e...

BACKGROUND Aspergillus fumigatus is a major opportunistic pathogen causing nosocomial infection. Hospital outbreaks of invasive aspergillosis have been associated with demolition and building construction. This study was designed to examine the impact of meteorologic factors and different periods of work on outdoor fungal airborne concentrations. METHODS The study was conducted at Necker Enfa...

Sludge dewatering and treatment may cost as much as the wastewater treatment. Usually large proportion of the pollutants in wastewater is organic. They are attacked by saprophytic microorganisms, i.e. organisms that feed upon dead organic matter. Activity of organisms causes decomposition of organic matter and destroys them, where the bacteria convert the organic matter or other constituents in...

The recent boom in construction activities and the continued urban development in Kuwait have resulted in the generation of massive quantities of construction/demolition material by-products that need to be removed from construction/demolition sites in the cities to landfill areas which are limited in the country. This paper explores the possibility and benefits of utilizing by-product material...

A case study on extensive fungal growth that occurred in an apartment building after firefighting efforts is described in this paper. Exposure to airborne microorganisms (both viable and total) was investigated by filter sampling in three periods before and during remedial actions after the fire. Material samples were also analyzed. Extensive mold growth was observed on the building materials a...

The high contribution of CO 2 emissions associated with pavements has driven research to assess the life cycle of concrete versus asphalt structures and to develop a strategy to reduce the carbon footprint. The life cycle of pavement has been studied with respect to CO 2 emissions in the use phase of concrete as well as after the concrete is demolished. However, only a few have considered the e...

This study was set to elucidate the concatenating effects caused by the transformation of Morogoro Road to accommodate Bus Rapid Transport (BRT) system. The study was conducted from 2013 to 2014 covering demolition, excavation and construction process of the new BRT system. Both field survey and literature reviews were applied, where the real case was taken at a strip between Manzese and Magome...
