It has been an important and interesting topic in soliton theory for searching for new Lax integrable or Liouville integrable systems as many as possible such that they are associated with certain evolution equations with physical meaning. The simple and efficient method to obtain continuous or discrete integrable systems was proposed Tu. Ma developed it and called it Tu scheme. By taking advan...

Feedback from AGN is thought to be key in shaping the life cycle of their host galaxies by regulating star-formation activity. Therefore, understand impact on star formation, it essential trace molecular gas out which stars form. In this paper we present first systematic study CO properties hosts at z~2 for a sample 27 X-ray selected spanning two orders magnitude bolometric luminosity (Lbol= 10...

the aim of this study is to evaluate the sport marketing mix and its seven elements (product, price, promotion, place, public relations, people, and physical evidence) in iran’s volleyball super league from the viewpoint of ministry of sport and volleyball federation managers in two conditions, namely existing and optimal. for this purpose, 102 subjects, among them the official staffs in the mi...

Peer-to-Peer technologies have been widely applied for multimedia applications. The super-peer based approach provides an efficient way to run applications by exploring nodes’ heterogeneity. In P2P live video streaming, even though the number of stable nodes is small, they have significant impact on the performance of the network. Thus, we present a super-peer-based overlay design, where stable...

BACKGROUND: Drought stress and climate changes cause damage led to reduction in agricultural production. OBJECTIVES: Evaluation the impact of different levels of super absorbent polymer (SAP) on reducing the effects of drought stress on some physiological traits and activity of some antioxidant enzymes in wheat crop. METHODS: Current research...

We consider and compare super Plücker Ptolemy relations from the perspective of constructing cluster algebras. develop structure Grassmannians Gr2|0(n|1) for arbitrary n, which was indicated earlier in our joint work with Th. Voronov. also analyze “weighted projective” case obtain a new simple form Grr|1(n|1). To this end, we establish properties Berezinians certain type matrices (which call “w...

To break the yield ceiling of rice production, a super rice project was developed in 1996 to breed rice varieties with super high yield. A two-year experiment was conducted to evaluate yield and nitrogen (N)-use response of super rice to different planting methods in the single cropping season. A total of 17 rice varieties, including 13 super rice and four non-super checks (CK), were grown unde...
