abstract in order to efficacy evaluation of some new herbicides to control of weeds in corn, a set of field studies were conducted in 2007 at 4 province of iran, including tehran (varamin), khuzestan, fars, and kermansh. treatments were arranged in a rcbd design with four replications. treatments consisted of ultima (nicosulfuron+nimsulfuron), lumax (mesotrion+s-metolacholor+terbuthlazine), ami...

0. This study is addressed to the following genre of topological problems. Let n be a subset of a manifold Wand ç>:2-*II be a parametrization of n by a manifold collection 2 . We seek a factorization 2 -+M-+W9 <p=F o /, where i is an inclusion of S in a manifold M of the same dimension as W and F is a map in a certain class, such that the invariants of (W, II, <p) in some reasonable sense deter...

For computing the geodetic coordinates r and X on the ellipsoid one needs information o f the gravity field, titus making it possible to reduce tl~e terrestrial observations to the reference surface. Neglect o f gravity fieM data, suck,, as deflections o f the vertical and geoM he~hts, results in misclosure effects, which can be described using the ob/ect o f anholonomity.

Introduction.-The Titus Canyon formation of Oligocene age, occurring in the Death Valley region of California, was described in a recent paper by Stock and Bode.' Brief mention was made at that time of the fossil mammals found in this formation. Among these, the titanotheres were the first to be discovered and moreover are known by the best preserved material. These types possess special intere...
