concerns have been raised about the adverse impact of dusty air pollution (dap) on human health. the aim of this study was to find the association between dusty air pollution based on air quality index (aqi) and the risk of allergic diseases in southwestern provinces of iran, with assessing cytokine profiles and lymphocyte immunophenotypes.in this case control study 148 individuals participated...
Background: Reducing the effects of climate change and air pollution is a global priority at present. To formulate effective policies for achieving such a reduction requires a good understanding of the underlying phenomena. This study assessed the role of Nasr Kashan Factory in the emissions of particulate matter (PM). Methods: In this cross-sectional study, PM concentrations at 9 stations ins...
The city of Tehran undergoes an increasing growth in population as well as industrial activities, both of which increase the concentration of air pollutants. The current research tries to turn a limited and focused system of air contamination measurement and control to an unlimited and extensive one that examines the concentration of each of the contaminants in any area of Tehran. Accordingly, ...
Demand for more accurate particulate matter forecasts is accumulating owing to the increased interest and issues regarding matter. Incredibly low concentration matter, which accounts most of overall often underestimated when a prediction model based on machine learning used. This study proposed concentration-specific separation overcome this shortcoming. Three models Deep Neural Network (DNN), ...
Objective: To determine the effect of Air Quality Index (AQI) in the first trimester of pregnancy on birth weight, placental weight, and the ratio of placental weight to the birth weight (pw-bw) in Isfahan. Materials and methods: This cross-sectional study was done on 312 consecutive pregnant women in Beheshti Hospital in Isfahan city in 2013. Information on air pollution was received from the ...
COVID-19 caused by the SARS-CoV-2 virus is a global health concern due to quick spread of disease. In Turkey, first confirmed case and death occurred on 11 15 March 2020, respectively. There lack research impact public transportation mobility Air Quality Index (AQI) around world. The objective this consider usage consequently AQI level in Turkey. Data collection for analysis air quality status ...
شناسایی و تعییین نمایۀ عمقی اکسیژن در سطح مواد، لایه های نازک و به ویژه در کاربردهای صنعتی که با طیف گسترده ای از اکسیدها استفاده می شود، بسیار ضروری است. در این بررسی، از دو روش آنالیز با باریکۀ یونی (iba)، یعنی پراکندگی الاستیک تشدیدی (res) برای اکسیژن (16o(α, α)16o) و واکنش هسته ای (16o(d, p1)17o و 16o(d, p0)17o)، برای به دست آوردن نمایۀ عمقی غلظت اکسیژن در آلومینای آندی نانوحفره استفاده شد....
Initially construed as the vital link between Saddam Husayn’s Iraq and al-Qaida in runup to war, Ansar al-Islam (AI) group formed Iraqi Kurdistan December 2001 has been subject of intense debate huge media coverage. In academic research, however, its history, evolution affiliation have received surprisingly little scrutiny. Commonly depicted an affiliated or a sub-group controlled by al-Qaida’s...
Air pollution is one of the biggest concerns in world but it has not been paid much attention developing countries. It necessary to design models and methods understand air countries reduce rate pollution. This paper proposes an Internet Things (IoT) Artificial Intelligence (AI)-based hybrid model predict Quality Index (AQI) with a practical case study public data sets. The sensor node deployed...
پدیده آلودگی هوا یکی از ر ه آور دهای توسعه صنعتی و اقتصادی است ، که با افزایش جمعیت ، گسترش شهر نشینی ، توسعه حمل و نقل و استفاده بی رویه از سوخت های فسیلی روز به روز بر شدت آن افزوده می شود. این پدیده امروزه به یکی از معضلات کلان شهر تهران تبدیل شده است . شاخص کیفیت هوا ( aqi ) ، نسخه ارتقاء یافته شاخص استاندارد آلودگی ( psi ) ، شاخص گزارش دهی روزانه کیفیت هوا می باشد و بیان کننده آن است که هو...
