Changes in dietary nitrogen flows in nineteenth century...
The estimation of disease prevalence in online search engine data (e.g., Google Flu Trends (GFT)) has received a considerable amount of scholarly and public attention in recent years. While the utility of search engine data for disease surveillance has been demonstrated, the scientific community still seeks ways to identify and reduce biases that are embedded in search engine data. The primary ...
Two Long-Term Ecological Research (LTER) sites now include urban areas (Baltimore, Maryland and Phoenix, Arizona). A goal of LTER in these cities is to blend physical and social science investigations to better understand urban ecological change. Research monitoring programs are underway to investigate the effects of urbanization on ecosystems. Climate changes in these urban areas reflect the e...
Many commentators have noted the existence of a historical correlation between cities and democratization. This image of the city as an inherently civic space is linked to the notion that the spatial concentration intrinsic to urban contexts promotes a democracy of proximity. Seen from this perspective, it is perhaps not surprising that the most urbanized region of the global south, Latin Ameri...

Survival rates were low in large 19th-century American cities. We ask whether this was attributable to a few “bad” wards or whether urban wards were uniformly bad. The paper employs two datasets. The Union Army database has been augmented with veterans who enlisted in and/or resided in Boston, Chicago, New York City (including Brooklyn), and Philadelphia. Additionally, the Historical Urban Ecol...
BACKGROUND Although the dispersion model approach has been used in some epidemiologic studies to examine health effects of traffic-specific air pollution, no study has evaluated the model predictions vigorously. METHODS We evaluated total and traffic-specific particulate matter < 10 and < 2.5 microm in aero-dynamic diameter (PM(10), PM(2.5)), nitrogren dioxide, and nitrogen oxide concentratio...
Today, access to sustainable environment for more presence of humans in open space should improve the quality of open spaces and human thermal comfort. Hence, the courtyard as an open space is an important element in solar radiation absorption and providing thermal comfort. The aim of this paper is to investigate the climatic performance of traditional courtyard houses, according to shading ...
Examining the planning of cemeteries in the urbanism system of Iran does not show a goodcondition. In fact, cemeteries in the most Persian cities have become large-scale open spaces outside the city. This couldcause irreparable damage to the cities because of the partial and/or improper use of the capacity of urban lands. Alongwith this, historical cemeteries within the cities have been abandon...
The energy audit for a building is a procedure designed mainly to obtain adequate knowledge of the energy consumption profile, identify, and quantify opportunities for energy savings by a cost-benefit analysis and report, clearly and comprehensively, about the obtained results. If the audit is referred to a building with a significant historical and artistic value, a compatibility evaluation of...
