In this study, Zn-doped calcium silicate (Zn-WO) materials were successfully synthesized. As precursors, Ca (OH)2, SiO2, and ZnO utilized, then the hydrothermal experiment was conducted for 6 hours at 1050°C. work, behavior of two groups raw exposed to isobaric different temperature circumstances is described. The synthesized sample examined using XRD, SEM, EDAX, Raman, BET, UV-Vis spectroscopi...
Workplace deviant behavior (WDB) and workplace ostracism (WO) have emerged as one of the most toxic behaviors that breed self-protection self-interest in today’s organizations. However, limited evidence is available on underlying factors, such organizational conflict (OC), knowledge-sharing (KSB) emotional intelligence (EI), explaining WO-WDB relationship. Hence, present study aims to introduce...
BACKGROUND The purpose of this study was to compare the shaping ability of the ProTaper Universal (PTU; Dentsply Maillefer, Ballaigues, Switzerland), WaveOne (WO; Dentsply Maillefer) and ProTaper Next (PTN; Dentsply Maillefer) in simulated L-shaped and S-shaped root canals respectively. METHODS 30 simulated L-shaped and 30 simulated S-shaped root canals in resin blocks were employed and rando...
Although vaccination of poultry for control of highly pathogenic avian influenza virus (HPAIV) H5N1 has been practiced during the last decade in several countries, its effectiveness under field conditions remains largely unquantified. Effective HPAI vaccination is however essential in preventing incursions, silent infections and generation of new H5N1 antigenic variants. The objective of this s...
[1] Aerosol single scattering albedo (wo) is a primary factor dictating aerosol radiative effect. Ground-based remote sensing of wo has been employed most widely using spectral sky radiance measurements made from a scanning Sun photometer. Reliable results can be achieved for high aerosol loadings and for solar zenith angle >50 . This study presents an alternative method using spectral direct r...
Herein, we report honeycomb nanostructured single crystalline hexagonal WO(3) (h-WO(3)) thin films in order to improve electrochromic performance. In the present investigation, honeycomb nanostructured WO(3) with different unit size and nanowire array with highly nanocrystalline frameworks have been synthesized via a hydrothermal technique. The influence of hydrothermal reaction time on the hon...
BACKGROUND Heart Rate Recovery (HRR) reflects the capacity of the cardiovascular system to reverse the vagal withdrawal caused by exercise. Scintigraphy with metaiodobenzylguanidine (I(123) MIBG) evaluates innervation and cardiac adrenergic activation. The association of these two methods is not well established. OBJECTIVE To evaluate the association between HRR and washout rate (WO) of I(123...
