a field study was conducted at the college of agriculture, shiraz university, shiraz, iran to evaluate the effect of different crop residue and nitrogen rates on yield and yield components of two dryland wheat (triticum aestivum l.) cultivars. the experiment was conducted as a strip split plot with four replications. vertical plots included two dryland current wheat cultivars (azar2 and nicknej...

pesticides are one of the major pollutants in the environment. the residue of pesticides has been reported to be at a critical level in agricultural crops, especially in greenhouse crops. tomato is considered as an important vegetable in iranian food basket and is produced in fields and greenhouses. so, the current study aimed to assess diazinon and oxydemeton-methyl levels in tomatoes sampled ...

Let m>2 and r be integers, let y0 be an integer in the least residue system mod m, and let X be an integer coprime to m with X ^ ± 1 (mod m) and (X ~ l)y0 + r ^ 0 (mod m). A sequence y0,yl9...of integers in the least residue system mod m is generated by the recursion yn+ x = Xyn + r (mod m) for n = 0, 1, . . . . In the homogeneous case r = 0 (mod m), one chooses y0 to be coprime to m. The seque...

Let K be a number field, let OK be the ring of integers, let K be an algebraic closure of K and let OK be the ring of integers of K. Let M 0 K be the set of finite places and let M∞ K be the set of infinite places. Let Kv be the completion of K at v and let Ov be the ring of integers of Kv. Let ℘v, kv, qv be the maximal ideal of Ov, the residue field Ov/℘v and the size of the residue field |kv|...

A b s t r a c t This letter discusses simple techniques for the implementation of fault detection in Residue Number System (RNS) arithmetic modules used in systolic arrays. The technique centres around a recently introduced linear systolic structure[1], and does not require a redundant residue system[2] for the detection process. It is shown that this structure can be used as the detection proc...

Theorem 1.1 (Theorem 4.1.1 of Raynaud’s paper). Let R be strictly henselian, mixed characteristic, with residue field of characteristic p, with v(p) = e (where the v of a uniformizer is 1). Let G be the generic fiber of a finite, flat, commutative R-group scheme G that is killed by p. Suppose e ≤ p− 1. The action of Gal(K̄/K) on det(G) is given by the tame character τ v(D̄(G)) p , where we will g...

Seventy years of different management treatments have produced significant differences in runoff, erosion, and ponded infiltration rate in a winter wheat (Triticum aestivum L.)–summer fallow experiment in OR, USA. We tested the hypothesis that differences in infiltration are due to changes in soil structure related to treatment-induced biological changes. All plots received the same tillage (pl...

Let R be an o-minimal expansion of a group in language which Th(R) eliminates quantifiers, and let C predicate for valuational cut R. We identify condition that implies quantifier elimination Th(R,C) the expanded by small number constants, which, turn, is implied having being universally axiomatizable. The applies example case when convex subring field its residue o-minimal.

Let Fq be a finite field with q elements with prime power q and let r > 1 be an integer with q ≡ 1 (mod r). In this paper, we present a refinement of the Cipolla-Lehmer type algorithm given by H. C. Williams, and subsequently improved by K. S. Williams and K. Hardy. For a given r-th power residue c ∈ Fq where r is an odd prime, the algorithm of H. C. Williams determines a solution of X = c in O...
