We consider nonlinear recurrences generated from the iteration of maps that arise from cluster algebras.More precisely, starting from a skew-symmetric integer matrix, or its corresponding quiver, one can define a set of mutation operations, as well as a set of associated cluster mutations that are applied to a set of affine coordinates (the cluster
Overhaul of distribution grid plays a decisive role in the operation and dispatch of power grid.With the increasingly expansion of power Sneakers for Men - Grey - Canvas Mesh Athletic Running Shoes grid scale, its structure tends to be complicated as well.The traditional overhaul plan mode is currently not able to meet the development demand of pow
The influence of the layered structure of plant leaves on the optical properties obtained with a homogeneous theoretical model was investigated.To this aim, silicone phantoms with different optical properties modeling synthetic leaf layers were fabricated to study a two-layer model of hydrangea red sensation the leaf.The optical properties were det
Introduction and Aim: The uThongathi Estuary was found to be in a poor ecological state and the water pollution was due to the discharge from the wastewater treatment plant, industrial, agricultural and residential sectors of Tongaat.The aims of this paper were therefore to explore the need for phytoremediation, as well as to show the importance of
Lysophospholipids (LPLs) and bile acids (BA) are commonly used as emulsifiers in aquaculture.This study investigated the effects of dietary supplementation of LPLs or BA on the growth performance, lipid deposition, and intestinal health of largemouth juveniles.Fish were randomly allotted into three groups in quadruplicate and fed sequal eclipse 5 b
