The present study was conducted at Khorassan Agricultural Research Center in order to determine the amount of seeds in nursery and the best transplanting date for black zira (Bunium persicum) bulbs from nursery to field and to find out the best cultivation pattern in the field. Treatments consisted of six seed rates (20, 60, 100, 180 and 220 kg/ha) which were sown on November 1996. Results reve...

Given a set S of n points in the plane, the disjoint two-rectangle covering problem is to find a pair of disjoint rectangles such that their union contains S and the area of the larger rectangle is minimized. In this paper we consider two variants of this optimization problem: (1) the rectangles are free to rotate but must remain parallel to each other, and (2) one rectangle is axis-parallel bu...

Results are reported for N* masses in the 1/2+ and 1/2− sectors on an anisotropic lattice. The gauge action is the usual plaquette plus rectangle type, the quark action is of the D234 type, both having tadpole-improved tree-level coefficients. Clear splittings from the nucleon ground state are observed with smeared operators and 500 configurations. The first excited states in each channel are f...

Abstract In this article we prove that all squares with sides of lengths $$\frac{1}{m+1}, \frac{1}{m+2}, \dots $$ 1 m + , 2 ⋯ can be packed in a rectangle one side fixed and rel...

A printed monopole antenna with CPW-fed is proposed. The proposed antenna includes a rectangle shape radiator, two ground planes with symmetrical notch and feed excitation. It covers the all ultra wideband (UWB 3.1GHz ~ 10.6GHz) and has 7.8GHz (2.8GHz ~ 10.6GHz) measured return loss bandwidth. In modifiable design, we choose to design the notches on the ground plane, the high of the proposed an...
