Fixed point results of F-rational cyclic contractive mappings on 0-complete partial metric spaces
( Forum-Editrice Universitaria Udinese SRL , 2018 , Article)Wardowski [19] introduced a new concept of contraction which called F-contraction and proved a fixed point theorem on complete metric space. Following this direction of research, in this paper, we introduce an F-rational ... -
Coronary Heart Disease Risk Factors among University Female Students
( Radcliffe Medical Press , 2017 , Article)Background: Coronary heart disease (CHD) is a main cause of morbidity and mortality globally. High levels of cholesterol are considered a major risk factor of CHD. This study sought to find out the prevalence of high ... -
Spatial modelling of contribution of individual level risk factors for mortality from Middle East respiratory syndrome coronavirus in the Arabian Peninsula.
( Public Library of Science , 2017 , Article)Middle East respiratory syndrome coronavirus is a contagious respiratory pathogen that is contracted via close contact with an infected subject. Transmission of the pathogen has occurred through animal-to-human contact at ... -
Analysis of spatial data with a nested correlation structure
( Wiley , 2017 , Article)Spatial statistical analyses are often used to study the link between environmental factors and the incidence of diseases. In modelling spatial data, the existence of spatial corre- lation between observations must be ... -
Disease mapping of Leishmaniasis outbreak in Afghanistan: spatial hierarchical Bayesian analysis
( Elsevier , 2012 , Article)Abstract ObjectiveTo analyze the spatial pattern of Leishmaniasis disease in Afghanistan, using provincial level geo-referenced data. The disease is contracted through bites from sand flies and is the third most common ... -
Spatially Correlated Time Series and Ecological Niche Analysis of Cutaneous Leishmaniasis in Afghanistan.
( MDPI , 2017 , Article)Leishmaniasis is the third most common vector-borne disease and a very important protozoan infection. Cutaneous leishmaniasis is one of the most common types of leishmaniasis infectious diseases with up to 1.2 million ... -
Radioactivity levels in the marine environment along the Exclusive Economic Zone (EEZ) of Qatar
( Elsevier , 2015 , Article)A study on 137Cs, 40K, 226Ra, 228Ra, and 238U was carried out along the EEZ of Qatar. Results serve as the first ever baseline data. The level of 137Cs (mean value 1.6 ± 0.4 Bq m 3) in water filters was found to be in the ... -
Multivariate multilevel models for attitudes toward statistics: multi-disciplinary settings in Afghanistan
( Taylor & Francis , 2016 , Article)The present paper focuses on examining students' attitudes and perception of statistics in Afghanistan universities and the factor structure of the statistical anxiety rating scale (STARS). In total, 209 undergraduate ... -
Joint spatial time-series epidemiological analysis of malaria and cutaneous leishmaniasis infection
( Cambridge University Press , 2017 , Article)Malaria and leishmaniasis are among the two most important health problems of many developing countries especially in the Middle East and North Africa. It is common for vector-borne infectious diseases to have similar ... -
Loading Rates of Dust and Metals in Residential Houses of Arid and Dry Climatic Regions
( Taiwan Association for Aerosol Research , 2016 , Article)Dust samples were collected from 38 naturally ventilated houses for 12 weeks. Effects of three variables in two groups each were evaluated: proximity to traffic density (main- and side-roads), cigarettes smoking (smoking ... -
Iterative scheme for an elliptic non-local free boundary problem
( Taylor & Francis , 2016 , Article)In this paper we treat a non-local free boundary problem arising in financial bubbles, where the model is set in the framework of viscosity solutions. We suggest an iterative scheme which consists of a sequence of obstacle ... -
Numerical Computation of the Conformal Map onto Lemniscatic Domains
( Springer , 2016 , Article)We present a numerical method for the computation of the conformal map from unbounded multiply-connected domains onto lemniscatic domains. For ℓ -times connected domains, the method requires solving ℓ boundary integral ... -
