The objective was to investigate effects of feeding lambs fresh versus dried Puccinellia. tenuiflora (Griesb.) Scribn. & Merr. on nutrient and water intake apparent digestibility. Twenty-four were offered or (48 hr) grass. dry matter (DM) content grass 65% the neutral detergent fiber exclude ash (aNDFom) 87% grass, whereas metabolizable energy concentration two forages similar. Lambs eating had...

Salinization has led to the deterioration of ecological environment, affected growth plants, and hindered development agriculture forestry. Arbuscular mycorrhizal (AM) fungi, as important soil microorganisms, play significant physiological roles in promoting plant nutrient absorption improving structure. Puccinellia tenuiflora (Turcz.) Scribn. et Merr. Songnen saline-alkaline grassland was sele...

vspace{0.2cm}In this paper, we design a data structure for the following problem. Let $pi$ be an $x$-monotone trajectory with $n$ vertices in the plane and $epsilon >0$. We show how to preprocess $pi$ and $epsilon$ into a data structure such that for any horizontal query segment $Q$ in the plane, one can quickly determine the minimal continuous fraction of $pi$ whose Fr{'e}chet and Hausdo...
