Irrigation and nitrogen (N) are two crucial factors affecting perennial grass seed production. To investigate the effects of irrigation N rate on yield (SY), components, water use efficiency (WUE) Cleistogenes songorica (Roshevitz) Ohwi, an ecologically significant grass, a four-year (2016–2019) field trial was conducted in arid region northwestern China. Two regimes (I1 treatment: at tillering...

The present study investigated the impact of dietary supplementation with nano-elemental, inorganic, and organic selenium (Se) on Se content, fatty acid (FA) composition, oxidative stability meat in 150 one-day-old broiler chickens. chickens were allotted into three groups: control (C), SS+SY, SeNP. C group received a diet without any added Se, while SS+SY SeNP groups fed diets containing 0.4 m...

We present multi-epoch, high signal-to-noise spectropolarimetry of the Raman-scattered emission lines of five S-type symbiotic binaries: CD−43◦14304, Hen 1242, M1-21, SY Mus, and V455 Sco. The Raman-line polarizations and magnitudes are used to estimate orbital parameters for these systems. Two of the five systems (CD−43◦14304 and SY Mus) have published radial-velocity orbits, which agree with ...

The difficulties associated with the appraisal of the determinacy properties of a three-dimensional sy em are circumvented by the introdu ion of a new geometrical argument. It brings about a complete typology of the eigenvalues moduli in discrete time three-dimensional dynamical sy ems and then provides a new apparatus for assessing from a geometrical andpoint the emergence of local bifurcation...
