Background: Inspection of the level of radioactivity from radionuclides in soil is important for the assessment of the exposure to natural radiation. Materials and Methods: Ten samples from soil were collected from different sites of Kirkuk-IRAQ and the level of natural radioactivity was measured using gamma-ray spectrometry based on a high purity germanium (HPGe) detector. Results: It was foun...

Introduction: The present study investigated the relatively high concentrations of natural radionuclides in raw material that used in ceramic manufacturing, and estimated the occupational exposure due to these activity concentrations. Material and Methods: A high-purity Germanium detector was used to determine naturally occurring radionuclide...

This study was designed to investigate causes of culling in industrial dairy herds in Fars province and to describe the pattern of reason-specific culling with respect to age of animal and interval from calving to culling. A total number of 9 dairy herds were selected for the study and information about culling reasons, birth date, last calving date and culling date was collected for culled cow...

the present paper has determined the radioactivity concentrations, which are due to natural occurrence of radionuclides along with heavy metal concentration in water, sediment, and fish from 2 reservoirs in ghana. heavy metal concentrations in all samples were generally within the who safe limits with the average activity concentrations of 238u, 232th, and 40k in water being respectively 0.42±0...

introduction: the majority of leukemia patients are acute leukemia patients, so that about 70.8% lymphoblastic leukemia were acute lymphoblastic leukemia (all) patients and 66.4 % of myeloid leukemia patients were acute myeloid leukemia (aml) in tehran metropolitan. during the last two decades, intensification of therapy by the use of high-dose cytarabine allogeneic stem cell transplantation in...

Deficits in specific cognitive and psychomotor capacities, such as attention, reaction time, memory, and hand-eye coordination ability are associated with increased crash risk, especially among older drivers (e.g., Anstey et al., 2005). Higher-order cognitive processes are also closely linked with hazard perception skills (e.g., Groeger, 2000). Employing a large professional driver sample, this...

BACKGROUND When comparing transfused versus nontransfused patients, erythrocyte transfusion is consistently associated with increased mortality. Nonetheless, unmeasured confounding may unduly influence this comparison. This unmeasured risk may have less influence on comparisons of patients undergoing surgery at hospitals with differing transfusion rates. METHODS Administrative databases were ...

In this paper, we consider series-parallel and parallel-series systems with independent subsystems consisting of dependent homogeneous components whose joint lifetimes are modeled by an Archimedean copula. Then, by considering two such systems with different numbers of components within each subsystem, we establish hazard rate and reversed hazard rate orderings between the two system lifetimes,...

BackgroundAtopic eczema affects up to 10% of adults and is becoming more common globally. Few studies have assessed whether atopic increases the risk death.ObjectiveWe aimed determine with were at increased death overall by specific causes assess varied severity activity.MethodsThe study was a population-based matched cohort using UK primary care electronic health records from Clinical Practice...
