Recent studies in both humans and animals suggest that air pollution is an important risk factor for type 2 diabetes mellitus (T2DM). However, the mechanism by which air pollution mediates propensity to diabetes is not fully understood. While a number of epidemiologic studies have shown a positive association between ambient air pollution exposure and risk for T2DM, some studies have not found ...
In this research, the effect of air pollution due to combustion of diesel oil on the performance parameters of mono-crystalline silicon (mc-Si) and polycrystalline silicon (pc-Si) photovoltaic solar panel is investigated in laboratory scale. Experiments were conducted in a solar simulator that was equipped with a chamber to control the air pollution. The air pollution is generated through the c...
Objective: There are many communities at risk by a series of air pollution episodes. Tehran is one of the most polluted cities in the world. The presence of one or more air pollutants with a certain concentration in a particular period of time can cause several adverse effects on human and animals’ well-being that can cause much morbidity. There are several pollutants in the ai...
BACKGROUND Epidemiological studies have reported associations between air pollution exposure and increases in cardiovascular morbidity and mortality. Exposure to air pollutants can influence cardiac autonomic tone and reduce heart rate variability, and may increase the risk of cardiac arrhythmias, particularly in susceptible patient groups. OBJECTIVES We investigated the incidence of cardiac ...
Introduction:Among the pollutants in waste gases, volatile organic carbons (VOCs) are very harmful for human, animals and plants. Formaldehyde is a member of VOCs family and is very toxic, mutagen and carcinogen. For removing formaldehyde, Some biological methods for treating waste gases such as bio-trickling filter reactor (BTFR) have been developed by scientists. The aim of this study was to ...
UNLABELLED : Air pollution has been a matter of great concern globally because of the associated health risks to individuals. The situation is getting worse in developing countries with more urbanization, industrialization and more importantly the rapidly growing population posing a threat to human life in the form of pulmonary, cardiovascular, carcinogenic or asthmatic diseases by accumulating...
investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Pollution of air resulting from toxic wastes emitted by large manufacturing plants and power-generation plants is a much-studied topic. The issue of health hazards arising from water pollution (see Wagner, Shamir, and Marks, 1994), storage and transportation of hazardous materials, and genetically-engineered food products has been a topic of intense debate and considerable research for the last...
urbanization expanse and population growth, as well as pilgrim's possibility of some cities provide overuse of vehicles and consequently increased air pollution. thus by considering the importance of the impact of air pollution on human health, in this study, air pollution in terms of pm10 using psi standard index and inverse distance weighting is zoned in mashhad. on the other hand, meteo...
BACKGROUND Exposure to particulate air pollution is associated with an increased risk of cardiovascular disease. The mechanism by which exposure increases risk is poorly understood but could involve changes in the flow properties of blood. OBJECTIVE The aim of this investigation was to assess the effect, in rats, of intratracheal instillation of particulate air pollution on leukocyte flow pro...
