(nil) = nil sigperm(x :: xs) = append(sigrot(x; x); sigperm(xs)) sigrot(x; nil) = nil sigrot(u; x :: xs)) = cond(issig(u); u :: sigrot(rotate(u); xs); sigrot(rotate(u); xs)) 4.4 Third transformation step Our objective is to get rid of the costly occurrences of append in sigperm. We introduce the new denition: sr(x; y; u) = append(sigrot(x; y); u) and the theorem: The complete denition of sigper...
Introduction: Ischemia/reperfusion (IR) injury involves a complex interrelated sequence of events. High levels of nitric oxide (NO) are generated with inducible form of nitric oxide synthase (iNOS) leading to the renal IR injury and glutathione (GSH) depletion. The present study was designed to investigate the effect of L-Nil (N6- (1-Iminoethyl)-L- lysine.hydrochloride), a selective inhibito...
Let R be a commutative ring with identity and Nil(R) be the set of nilpotent elements of R. The nil-graph of ideals of R is defined as the graph AG_N(R) whose vertex set is {I:(0)and there exists a non-trivial ideal such that and two distinct vertices and are adjacent if and only if . Here, we study conditions under which is complete or bipartite. Also, the independence number of is deter...
For a ring R, R[x] is a left nearring under addition and substitution, and we denote it by (R[x], +, ◦). In this note, we show that if nil(R) is a locally nilpotent ideal of R, then nil(R[x], +, ◦) = nil(R)0[x], where nil(R) is the set of nilpotent elements of R and nil(R)0[x] is the 0-symmetric left nearring of polynomials with coefficients in nil(R). As a corollary, if R is a 2-primal ring, t...
water and sediment samples were collected from six different stations, located along the nil river between february and june 2015. concentrations of cadmium, lead, zinc, and copper were determined. the extent of the sediment pollution was assessed, using the multiple pollution indices, namely contamination factor (cf), pollution load index (pli), and the geoaccumulation index (igeo). the result...
Soil salinity reduces soybean growth and yield. The recently identified GmSALT3 (Glycine max salt Tolerance-associated gene on chromosome 3) has the potential to improve soybean yields in salinized conditions. Here we evaluate the impact of GmSALT3 on soybean performance under saline or non-saline conditions. Three sets of near isogenic lines (NILs), with genetic similarity of 95.6-99.3% betwee...
