background : essential oils are the volatile fraction of aromatic and medicinal plants created after extraction by steam or water distillation. species of the genus citrus (rutaceae) have been widely used in traditional medicine as volatile oils and are currently the subject of numerous research. citrus essential oil consists of different terpens that have antitumor activities. this study deter...

We analyze spectra for a large sample of 578 Active Galactic Nuclei to examine the relationships between broad emission line properties and central supermassive black hole (SMBH) mass. We estimate SMBH masses by applying the virial theorem to the C IV λ1549 broad emission line. Although the FWHMs of C IV and Hβ appear nearly unrelated in individual objects, these FWHMs are well correlated when ...

this experiment was carried out to study the effects of different levels of canola meal of different fat sources on the egg quality, performance as well egg yolk cholesterol during the first 12 weeks of age in laying hens (hy-line w-36). throughout the experiment a total of 432 hens were employed in a completely randomized design in a factorial arrangement of 3×4, with three levels of canola me...

The effect of photon frequency redistribution by line branching on mass-loss rates for hot luminous stars is investigated. Monte Carlo simulations are carried out for a range of OB-star models which show that previous mass-loss calculations which neglect nonresonance line scattering overestimate mass-loss rates for luminous O stars by ∼ 20 per cent. For luminous B stars the effect is somewhat l...

abstract adrenal gland cysts are rare indications of adrenal diseases, which are commonly asymptomatic. in radiological studies, these cysts, known as incidentalomas, are often detected by coincidence accounting for 6% of the population. adrenal incidentalomas are commonly detected, and autonomous cortisol hypersecretion is the most prevalent abnormality associated with these masses. since this...

In a protoplanetary disk, the inner edge of the region where the temperature falls below the condensation temperature of water is referred to as the ’snow line’. Outside the snow line, water ice increases the surface density of solids by a factor of 4. The mass of the fastest growing planetesimal (the ’isolation mass’) scales as the surface density to the 3/2 power. It is thought that ice-enhan...

the aim of this study was to recognize the effects of dietary hempseed (hs) and hempseed oil (ho) on performance, egg quality and blood parameters of laying hens. a total of 320 hy-line 55-weeks laying hens were randomly allotted to eight dietary treatments with five replicates (8 birds each). the experimental treatments were offered as a completely randomized design as follow: control group (n...
