Introduction: There are significant gender differences in the epidemiology and presentation of cardiovascular diseases (CVDs), physiological aspects of CVDs, response to diagnostic tests or interventions, and prevalence or incidence of the associated risk factors. Considering the independent influence of gender on early dire consequences of such diseases, this study was conducted to investigate...
In this paper, β-PbO nanoparticles were prepared by microwave irradiation. Then, the PbO nanoparticles with size of 32 nm were doped in the Bi2-xPbxSr2Ca2Cu4Oy superconductor with x = 0.0, 0.2, 0.4 and 0.6. The samples were synthesized by the standard solid state reaction method. The structural properties, microstructure and morphology of the samples have been studied by XRD and SEM. After synt...

Aims and background: PACU, which locates next to surgery room is designed to take care of patients recovering from anesthesia and surgery. Patients which are transferred to this room are exposed to risks and irreparable complications. Therefore, standardization of this unit has a great importance for proper evaluation of patients. Therefore researchers aimed to assess the condition of PACU ...
It is shown that the Newey-West (1987) Heteroskedasticity and Autocorrelation Consistent (HAC) covariance matrix estimator can greatly understate the standard errors of OLS regression coefficient estimates in finite samples, and therefore comparably overstate t-statistics. Although the bias vanishes in infinite samples and is tolerable in samples as small as 10, it can lead to t-statistics that...
