Jacquemin et al. address an important topic in the field of epidemiology and public health by increasing understanding of the triggers of air pollution annoyance across 25 population centres in 14 countries in Europe. No study, however commendable, is without its limitations and this one is no exception. We offer a commentary of their article ‘Annoyance Due to Air Pollution in Europe’ as a mean...
The air quality in Taiwan, at present, is determined by a pollution standard index (PSI) that is applied to areas of possible serious air pollution and Air Quality Total Quantity Control Districts (AQTQCD). Many studies, both in Taiwan and in other countries have examined the characteristics and levels of air pollution with PSI. This study uses air quality data collected from eight automatic ai...
In recent years, air pollution has become a major worldwide concern. Air pollutants can affect metabolic activity, impede healthy development, and exhibit carcinogenic and toxic properties in humans. Over the past two decades, the use of microbes to remove pollutants from contaminated air streams has become a widely accepted and efficient alternative to the classical physical and chemical treat...
Under the National Ambient Air Quality (NAQM) Monitoring program, air quality in the city of Cochin is being regularly monitored by Central Pollution Control Board. Air quality management programme requires reliable information of air quality collected, evaluated and analysed regularly. This is of paramount importance in protecting man and his environment from damaging exposure to air pollution...
Background. The relationship between air pollution and exacerbation of respiratory diseases is well established. Nevertheless, its association with hemoptysis has been poorly investigated. This paper describes the relationship of air pollutants with severe hemoptysis. Methods. All consecutive subjects with severe hemoptysis during a 5-year period were included. The relationship between the cont...
The aim of this document is to provide an overview of the models used to develop a workkow model of the Air Campaign Planning (acp) process. The models were used by the O-Plan project to develop a demonstrator of the O-Plan system as a \planning to plan" aid for the agenda of the control panel of Air Campaign Planning Tool (acpt). The role of O-Plan was to allow users to identify tool(s) e.g. e...
کیفیت گشتاور یک موتور سنکرون مغناطیس دایم داخلی نسبت به برخی از پارامترهای ابعاد رتور حساس است و این حساسیت می تواند برای کاهش cogging torque و نوسان گشتاور موتور استفاده شود. از آنجا که یک قسمت از نوسان گشتاور،cogging torque است، در این پایان نامه، یک روش جدید برای کاهش cogging torque با استفاده از مدل مغناطیسی ساده شده موتور انجام می شود. نتایج روش جدید منجر به شکل دهی جدید air bridge و موتور...
abstract background: bioaerosol is defined as airborne particles such as living organisms include bacteria, fungi and their related metabolites, such as endotoxin. over the recent years, health effects of bioaerosols such as infectious and respiratory diseases, acute toxic effects, allergies and cancer have been considered. the aim of this study was to evaluate the bacterial and fungal concentr...
asthma is one of the most common diseases in childhood, which has been increased during last decade because of epidemiological pattern changes with climate and industrialization of the communities. there are some controversies on the relationship between air pollution and asthma. tehran, as the capital of iran, is one of the densest populations and is one of the most polluted cities in the worl...
an investigation was made to study the residual activity and air- borne effect of pirimiphos- methyl, at 2g a.i./m2 in hut scale trials on different surfaces in kazeroun, and bandar-abbas, south of iran. in kazeroun area, bio-assay contact mortality test with pirimiphos methyl on mud, wood, cement and plaster surfaces, 54 days after hut spraying, decreased from 100% to 46.7%, 61.25%, 36.6% and ...
