Introduction: Particulate matter (PM) increases the risk of heart disorders. Gallic acid (GA) with strong antioxidant properties has shown an effective role in reducing the complications of various diseases. The aim of this study was to evaluate the protective effect of Gallic acid in preventing cardiac arrhythmias due to exposure to particulate matter. Methods: In this study, 40 rats were pla...
uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...
the present study aimed at exploring cognitions of iranian english teachers within the context of english for academic purposes (eap). to this end, the cognitions of two groups of eap teachers with respect to their pedagogical content knowledge (pck) and their sense of professional identity (pi) were probed. two language teachers and two content instructors who had at least five years of eap te...
in this study, the diversity and distribution of economical bony fishes in less-than-ten-meter depths, cpue and population features such as total length, weight and age were investigated in the southern part of the caspian sea in 1385-6. sampling was done in five regions: amir abad, larim, izdeh, kheyroud, and nashtarood with gilnet in mesh sizes of 26, 33, 40, 60, 100, and 150 mm. in total, 22...
Bacterial communities in PM2.5 and PM10 inside the cage broiler houses before and after disinfection
Background: Air in broiler houses is contaminated with considerable amounts of microbial aerosols, which affects the health of humans and birds. Thorough cleaning and disinfecting should be carried out to reduce particulate concentrations and minimize airborne microorganisms. Aims: To evaluate the effects of cleaning and disinfecting measures on bacterial commu...
Backgrounds and Objectives: The dispersion of particulate matter has been known as the most serious environmental pollution of cement plants. In the present work, dispersion of the particulate matter from stack of Kerman Cement Plant was investigated using Computational Fluid Dynamics (CFD) modeling.Materials and Methods: In order to study the dispersion of particulate matter from the stack, a ...
OBJECTIVE To compare tobacco smoke-derived particulate levels in transportation and hospitality venues with and without smoking in 32 countries using a standardised measurement protocol. METHODS The TSI SidePak AM510 Personal Aerosol Monitor was used to measure the concentration of particulate matter less than 2.5 microns in diameter (PM(2.5)) in 1822 bars, restaurants, retail outlets, airpor...
OBJECTIVE Using data on fine particulate matter less than 2.5 μm (PM2.5) concentrations in smoking and non-smoking homes in Scotland to estimate the mass of PM2.5 inhaled by different age groups. METHODS Data from four linked studies, with real-time measurements of PM2.5 in homes, were combined with data on typical breathing rates and time-activity patterns. Monte Carlo modelling was used to ...
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
Background and Objective: This study was conducted to investigate the long-term temporal trends and spatial variations of ambient PM10, PM2.5, O3, concentrations in Tabriz city during the years 2006-2017. Materials and Methods: Real-time hourly concentrations of PM10, PM2.5, O3 measured at nine air quality monitoring stations (AQMSs) were obtained from the Tabriz Department of Environment (TDo...
