This study is an attempt to analyze the primary school enrollment status in the city of Lahore; and provide estimates regarding the impact of household’s quantitative characteristics on enrollment decision. Primary data is collected from 3320 households where 2520 households belonged to the urban areas and 800 households belonged to the rural areas. Computations are carried out using both OLS a...
Introduction: Smoking is considered as the first preventable cause of mortality worldwide. Smoking cessation is influenced by many factors including social, familial and individual aspects. High nicotine dependency is a remarkable cause that makes cessation laborious for the smoker. There are many modalities to estimate the rate of nicotine dependency in practice among which Fagerstrom test is ...
Based on the importance of sustainability of the relationship between couples, the purpose of this research was conducted to investigate the effect of spouse-specific dependency and gender on entrapment and couple burnout in married students of Islamic Azad University of Qom. Participants included 350 students of Azad University of Qom. Married men and women were enrolled in the years 2015-2016...
In this paper, we establish a discrete time Geom/G/1 queue with setup-close delay-close down based on operation mechanisms with Switch Virtual Channels (SVC). Different from conventional intricate and time consuming imbedded Markov renewal processes, we use the factorization principle of discrete time queues with general vacation to analyze the response time, connection establishment ratio, ope...
WO3 thin films were deposited by pulsed laser deposition (PLD) on glass substrates at 100 mTorr oxygen pressure. Monodispersed palladium nanoparticles (50 nm) were synthesized by hydrogen reduction of PdCl2 drop-casted on the surface of the films. For oxyhydrogen detection, first a saturated coloration by 10%H2/Ar was prepared. Then different oxygen flow with certain O2:H2 ratios were exposed t...
The MINOS experiment has observed a rise in the underground muon charge ratio rμ = μ /μ. This ratio can be related to the atmospheric production ratios of π/π and K/K. Our analysis indicates that the relevant variable for studying the charge ratio is E μ cos θ, rather than E μ . We compare a simple energy dependent parameterization of the rise in the charge ratio with more detailed previously p...
