in this study, different derivative spectrophotometric methods are proposed for the simultaneous determination of chlorpheniramine maleate (cp), phenylephrine hcl (pe) and phenylpropanolamine hcl (pp) in their ternary mixtures and in pharmaceutical dosage forms. spectra of single component and ternary mixtures of various concentrations and combinations from zero- to fourth-derivation were obtai...

A graph is crossing-critical if the removal of any of its edges decreases its crossing number. This work is motivated by the following question: to what extent is crossingcriticality a property that is inherent to the structure of a graph, and to what extent can it be induced on a noncritical graph by multiplying (all or some of) its edges? It is shown that if a nonplanar graph G is obtained by...

drought is one on the most important factors limiting the productivity of spring chickpea in drylands of iran. sixtym genotypes of chickpea from icarda's germplasm accessions, as well as one drought susceptible check (ilc 3279), were sown in spring of 2010 at two locations, sanandaj and maragheh, in the western highlands of iran for one year. the experiment in each location was laid out in a ra...

BACKGROUND The role of the phosphatidylinositol-3 kinase signaling pathway in the development of acral melanoma has recently gained evidence. Phosphatase and tensin homologue (PTEN), one of the key molecules in the pathway, acts as a tumor suppressor through either an Akt-dependent or Akt-independent pathway. Akt accelerates degradation of p53. OBJECTIVE We assessed the expression of PTEN, ph...

Effective formation and implementation of forest policy can only be achieved with orientation to the most important goal—increasing society’s welfare. The global problem is, at present, that impact forests on society welfare indexes have not been identified. aim study is design an assessment model assess Lithuanian index. was determined by multiplying country’s index contribution coefficient. I...

Two approaches to calculating distribution energy losses are developed in this paper. The first one is based on the fuzzy load flow, and the other one uses fuzzy clustering technique. The attention at the first approach is devoted to forming the fuzzy numbers that represent loads. Data accessible from the measurements in corresponding substations are considered in this process. Using formed fuz...

Recall that we are interested in the conditioning quality of randomized sketches constructed by RandNLA sampling and projection algorithms. For simplicity of comparison with the Blendenpik paper, I’ll state the results as they are stated in that paper, i.e., with a Hadamard-based projection, and then I’ll point out the generalization (e.g., to leverage score sampling, to other types of projecti...
