there are a little information about nutritive value of alfalfa harvested at different cuts and different cutting time (morning and afternoon) in semiarid climate condition of north east of iran. effects of different harvesting cuts and cutting time (6 a.m and 6 p.m) of alfalfa hay at early bud stage on chemical composition and in vitro gas production fermentation profiles were studied in this ...

We assume some standard choices for the branch cuts of a group of functions and consider the problem of then calculating the branch cuts of expressions involving those functions. Typical examples include the addition formulae for inverse trigonometric functions. Understanding these cuts is essential for working with the single-valued counterparts, the common approach to encoding multi-valued fu...

In this paper we address the task of finding convex cuts of a graph. In addition to the theoretical value of drawing a connection between geometric and combinatorial objects, cuts with this or related properties can be beneficial in various applications, e. g., routing in road networks and mesh partitioning. It is known that the decision problem whether a general graph is k-convex is NP-complet...
