A medium is a medium is a medium. As the sentence says, there is no difference between occult and technological media. Their truth is fatality, their field the unconscious. Any sufficiently advanced technology is indistinguishable from magic. The urban ether swims with a multitude of invisible particles: the residue of ash and aerosols, signals and light. Circulating through the city is the dus...

Introduction: Road dust is a group of solid particles that are presented in the urban areas and are originated from both natural and human-induced sources. This study aims to determine concentrations of heavy metals in urban dusts in Behbahan to identify their natural or anthropogenic sources. Materials and Methods: In this study, a total of 20 samples were collected from main roads with diffe...

Vehicular ad-hoc networks are expected to be a key enabling technology for the development of future Intelligent Transportation Systems (ITSs), by delivering a wide range of services, spanning from safety alerting to route guidance and entertainment. Most of ITS applications require vehicles on the road to access the Internet through wireless communications with road-side units. The high vehicl...

The mitigation potential of avenue tree species needs a sound understanding, especially for landscape planning or planting tree species on roadside, especially in city limits where there is huge traffic due to more number of vehicles. A preliminary study was conducted to investigate the impact of heavy traffic movement and pollution thereof on physiological functioning of Lagerstroemia speciosa...

This study examined the spatial, socioeconomic status (SES), and temporal patterns of ambient air pollution in Accra, Ghana. Over 22 months, integrated and continuous rooftop particulate matter (PM) monitors were placed at a total of 11 residential or roadside monitoring sites in four neighborhoods of varying SES and biomass fuel use. PM concentrations were highest in late December and January,...

With a population of 5.5 million and a limited amount of land (1046 km2), Hong Kong is one of the most densely populated areas in the world. Due to the decentralization scheme to ease the densely populated centres, the rural area has been urbanized rapidly. The so-called 'satellite' cities in the New Territories have developed and expanded tremendously. As a result, housing estates are interspe...

Accepted for publication 7 July 1993 Abstract Objective-To determine the prevalence of syphilis and the prevalence and incidence of self-reported STD syndromes in the population of Mwanza Region, North-Western Tanzania. Methods-A population-based random cluster sample survey, stratified by rural, roadside or urban residence, of 4173 individuals aged 15-54 years was performed in 1990-91. The ser...

Ninety-six particulate matter (PM10) chemical source profiles for geological sources in typical cities of southwest China were acquired from Source Profile Shared Service in China. Twenty-six elements (Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Sr, Cd, Sn, Sb, Ba, Be, Tl and Pb), nine ions (F−, Cl−, SO4, NO3, Na+, NH4, K+, Mg2+ and Ca2+), and carbon-containing species...
