We develop the approach to the problem of integrable discretization based on the notion of r–matrix hierarchies. One of its basic features is the coincidence of Lax matrices of discretized systems with the Lax matrices of the underlying continuous time systems. A common feature of the discretizations obtained in this approach is non–locality. We demonstrate how to overcome this drawback. Namely...

INTRODUCTION In a previous report, we have shown that antisera prepared against a mouse tumor (the Wagner osteogenic sarcoma) contained antibodies capable of localizing in vivo in the mouse tumor, while antisera prepared against normal mouse organs did not. We had already shown that antisera prepared against normal rat (2,4, 7, 9,10) and mouse tissues (5) contained antibodies capable of localiz...

the extensive use of traditional irrigation systems has led to overexploitation of groundwater and overuse of surface water in theurmia  lake catchment (ulc) area ofiran. the purpose of this study was to model the adoption process of drip irrigation system (dis) by apple orchardists (aos) using the five stages of roger’s model for innovation decision process (idp). survey method of applying que...
