introduction: eugenol (eg), a compound extracted from clove tree, is known for its anti- anaphylactic, anti-inflammation, antiseptic, antibacterial and analgesic properties as well as chain breaking antioxidant in inhibition of lipid peroxidation. retinoic acid (ra), one of the synthetic derivatives of vitamin a, has been frequently used for treatment of face acne. in our studies eg was used to...

Background. The importance of physical activity (PA) for maintaining and improving health status increases with each passing day. Objectives. The present study aimed to examine the effects of PA and nutritional education programs applied to 12th-grade students on body mass index (BMI), PA level, and eating habits during the COVID-19 pandemic. Methods. One hundred fifty-nine 12th grade student...

This study was designed to experimentally measure the thermal and electrical conductivities of Aluminium Nitride/Ethylene Glycol (AlN/EG) nanofluids. Transmission electron microscopy (TEM) was used to characterize the shape of AlN nanoparticles. Nanofluids with different particle volume concentrations of 0.5%, 1%, 2%, 3%, 4%, and 5% were utilized. The thermal and electrical conductivities of the...

Background: The aim of the study was to compare the effects of two different concentrations of cryoprotectants by Cryotop vitrification on survival and Heat shock protein 72 (Hspa1a) expression of two-cell mouse embryos. Materials and Methods: Different cryoprotectants’ concentrations of the combination of dimethyl sulfoxide (DMSO) and ethylene glycol (EG) were used and compared with each other...

Let M be a compact connected Fujiki manifold, G semisimple affine algebraic group over C with one simple factor and P fixed proper parabolic subgroup of G. For holomorphic principal G–bundle EG M, let EP the P–bundle EG⟶EG/P given by quotient map. We prove that following three statements are equivalent: (1) ad(EG) is numerically flat, (2) line bundle ⋀topad(EP)⁎ nef, (3) for every reduced irred...

The building sector is targeting net-zero emissions through the integration of renewable energy technologies, especially for space cooling and heating applications. In this regard, use solar thermal concentrating collectors vital importance. performance these increases by using an efficient fluid such as a nanofluid due to their high conductivity. This research addresses preparation, stability ...
