in this paper we investigate the behavior of solutions, stable and unstable of the solutions a second-order rational difference equation. also we will discuss about the behavior of solutions a the rational system, we show these solutions may be stable or unstable.

In this article we describe two areas of recent progress in the construction of accurate and robust ®nite di€erence algorithms for continuum dynamics. The support operators method (SOM) provides a conceptual framework for deriving a discrete operator calculus, based on mimicking selected properties of the di€erential operators. In this paper, we choose to preserve the fundamental conservation l...

Modigliani and Miller showed that the market value of company is in- dependent its capital structure, suggested dividend policy makes no dierence to this law one price. We experimentally test MM theorem in a complete with two simultaneously traded assets, employing experimental treatment variations. The first variation involves stream. According payout order either identi- cal or independent. s...

The time dependence of B d B d mixing has been observed in events containing high-P t leptons using a highly inclusive v ertexing method to determine the B decay position. The initial state B hadron avor was determined using the large forward-backward asymmetry provided by the highly polarized electron beam of SLC in combination with a jet charge technique. From a sample of 150,000 hadronic Z d...

Growth and development of fall armyworm, Spodoptera frugiperda (J. E. Smith), were compared in two laboratory trials between individuals oered transgenic maize seedlings, conventional maize seedlings, or artificial diet. Transgenic maize seedlings in the first and second trials expressed Cry9C (Event CBH 351) and Cry1A(b) (Event MON 810) Bacillus thuringiensis (Berliner) (Bt) endotoxin genes, r...
