We report the results of a search for binarity among young stars, performed in the Scorpius-Centaurus OB association on a sample of 118 X-ray selected T Tauri stars. We use speckle interferometry and direct-imaging observations to find companions in the separation range 0.13′′ – 6′′. After corrections to account for confusion with background stars and for the bias induced by the X-ray selection...

Integrating use of seedings of perennial cool-season grasses with native range is used to increase available forage and for maintaining a high plane of nutrition for grazing livestock. Our goal was to evaluate performance of yearling cattle and stand persistence of 3 released wheatgrass cultivars. Twice replicated 3-ha pastures were seeded to ‘Rosana’ western wheatgrass [Pascopyron smithii (Ryd...

A significant portion of the irrigated acreage in the intermountain western U.S. is comprised of cool season grass pastures. Droughts, coupled with increasing demands for limited water supplies in the region, have decreased the water volumes available for irrigating these pastures and other crops. Consequently, relationship between crop yield and irrigation (water production functions) should b...

The long wavelength emission of protostellar objects is commonly attributed to a disk of gas and dust around the central protostar. In the first stages of disk accretion or in the case of high mass protostars, the disk mass is likely to be sufficiently large, so that the disk self-gravity may have an impact on the dynamics and the emission properties of the disk. In this paper we describe the s...

Methanol extract from aerial parts of Sideritis libanotica Labill. subsp. linearis (Bentham) Borm. were investigated for its in vitro antiproliferative activities against Vero, HeLa and C6 cells. The tests were carried out as dose-dependent assay starting from 25 μg/mL to 250 μg/mL. The extract found to be active against African green monkey kidney (Vero), human uterus carcinoma (HeLa) and Rat ...
