The relationship between meteorological conditions and the levels of PM2.5 in Krasnoyarsk city atmosphere for period from 2019 to 2022 were investigated. data National Centers Environmental Prediction Global Forecast System (NCEP GFS) reanalysis model was used. obtained ground monitoring stations. Analysis variances (one-way two-way ANOVA) Tukey Test showed statistically significant differences...

an important factor that interferes with the bonding between the root canal wall and resin cement is the root canal sealer remnant. there is controversy about the effect of eugenol-containing sealers on the bond strength between resin cements and fiber post. the aim of this study was to evaluate the effect of the type of endodontic sealer on the bond strength of frc posts cemented with resin ce...

sex hormone is supposed to modify pain sensitivity. the aim of the present study was to investigat, the role of 2 adrenergic receptors in nociception using formalin test. formalin test was performed by subcutaneous injection of 50 ml formalin (%2.5) solution into hind paw. animals were divided into 4 groups as control group (intact animal), sham group (received 2µl of artificial csf by icv rout...

PURPOSE The aim of this Fourier transform infrared (FTIR) spectroscopic study was to measure the degree of conversion (DC) of dual-cured resin cements light-irradiated through zirconia ceramic disks with different thicknesses using various light-curing methods. MATERIALS AND METHODS Zirconia ceramic disks (KT12) with three different thicknesses (1.0, 2.0, and 4.0 mm) were prepared. The light ...

The aim of this study was to assess the influence of sealer and light-curing unit on regional bond strength of resin composite to the weakened roots. Ninety roots of incisors were experimentally weakened, subjected to biomechanical preparation and filled with either Endofill, AH Plus or MTA Fillapex The roots were desobturated e reinforced with resin composite and fiber post light-activated wit...

the purpose of this research was to compare block, random and randomized block training on the acquisition, retention and transfer of volleyball serves. for this purpose, 34 students of shomal university were selected randomly and after primary rules of volleyball were explained and instructed and pretest was performed, they were divided into 3 groups (block, random and randomized block trainin...
