The work reported in this paper was carried out to study the trends of PM2.5 (particles with an aerodynamic diameter 2.5 µm or less) concentrations and source apportionment monitored at urban residential site Lahore, Pakistan. aerosol samples were collected for 2 days a week 12 h interval day, both dry wet seasons, on ZefluorTM filter papers using Thermo-Electron Corporation Reference Ambient Air Sampler (RAAS). Total 310 during period under study, i.e., from November 2005 December 2007....
This paper presents the finding of a study undertaken to determine naturally occurring radionuclides present in commonly used building materials for dwellings and workplaces four districts Punjab Province, Pakistan. The concentrations (226)Ra, (232)Th (40)K were measured by using gamma-ray spectroscopy. A total 80 samples collected from various manufacturers suppliers studied area. specific activities samples, results ranged minimum values 9 ± 1, 2 27 8 Bq kg(-1) maximum 106 5, 133 5 914 21...

An indoor radon survey has been carried in 120 schools situated four districts of the Punjab province, namely Attock, Chakwal, Jhelum, and Rawalpindi. In each season, a total 360 CR-39-based detectors were installed selected schools. After exposure etched 6M NaOH at 80°C solution for 16 h tracks densities, which are related to concentration, measured. Indoor concentration varied from 18 ± 7 168 5 Bq·m -3 with an average value 52 9 . High values found summer whereas lower recorded autumn...

Brick, sand, marble and cement are mainly used for the construction of dwellings in Pakistan. Therefore, knowledge presence natural radioactivity these materials is great importance order to assess radiological hazards associated with them. In this context, specific activities 226Ra, 232Th 40K were measured brick, samples collected from different localities North West Frontier province federally administered tribal areas, Pakistan, using a P-type coaxial high-purity germanium spectrometer....
It is a well known fact that natural radionuclides are the major contributors towards gamma ray exposure received by general public. In this context, soil samples were collected from Islamabad capital territory and activities due to (226)Ra, (232)Th, (40)K (137)Cs measured using spectrometry: ranged 41.5-106.2 Bq kg(-1), 4.0-193.8 325.3-657.4 kg(-1) 1.6-9.45 respectively. From activities, external hazard index, internal absorbed dose rate mean annual effective calculated. External indices...
A series of experiments were carried out to study the effect moisture content on radon exhalation rate from soil, sand and brick samples that collected North West Frontier Province Federally Administered Tribal Areas Pakistan, using CR-39-based dosimeters. After processing, prepared by adding 15, 30 45% contents (by weight) placed in plastic containers. The dosimeters installed it at heights 25 cm above surface samples. These containers then hermetically sealed exposed for 60 65 days....

This article extends the exploration of solutions to issue flame propagation driven by pressure and temperature in porous media that we introduced earlier papers. We continue consider a p-Laplacian type operator as mathematical formalism model slow fast diffusion effects, can be given non-homogeneous flames. In addition, introduce forced convection any possible induced flow media. depart from previously known models further substantiate our driving equations. From standpoint, goal is deepen...
The study aimed to investigate the concentration of atmospheric particulate matter (PM2.5, PM10), carbon monoxide (CO) and sound level from traffic areas in Mymensingh city. Airveda air quality monitor, Testo 317-3 meter were used measure CO level, respectively. Samples collected twenty-one locations for consecutive seven days. PM2.5 fluctuated 63 µgm-3 231.14 where average concentrations 99.85 µgm-3, 109.54 114.70 during morning, noon afternoon, highest was found at Bypass Mor (231.14...
