The Boundedness of Cauchy Integral Operator on a Domain Having Closed Analytic Boundary

In this paper, we prove that the Cauchy integral operators (or Cauchy transforms) define continuous linear operators on the Smirnov classes for some certain domain with closed analytic boundary

Tribonacci and Tribonacci-Lucas Sedenions

The sedenions form a 16-dimensional Cayley-Dickson algebra. In this paper, we introduce the Tribonacci and Tribonacci-Lucas sedenions. Furthermore, we present some properties of these sedenions and derive relationships between them.Comment: 17 pages, 1 figur

Studies On the Recurrence Properties of Generalized Pentanacci Sequence

In this paper, we investigate the recurrence properties of the generalized Pentanacci sequence and present how the generalized Pentanacci sequence at negative indices can be expressed by the sequence itself at positive indices

New Methods in the Synthesis of (Meth)Acrylates

Generally, the words “reactive polymers” and “functional polymers” mean the same thing and are used interchangeably in most studies and describe cross-linked (insoluble) bead-structured resins containing chemically reactive functional groups. In this way, reactive polymers are widely used as polymeric reagents or polymer supports in biochemical and chemical applications. Functional (meth)acrylates referred here to supply “functional esters” ruins as a general reactive group precursor. In other sense, the leaving (activating) groups of these monomers may easily react with the alcohols and amines carrying the desired reactive groups and therefore, in general, provide a single reaction step for the synthesis of reactive polymers. In this paper, we suggest new routes for a new (meth)acrylate-based monomers and polymers. Also, the synthesis of a serial new (meth)acrylate esters including amide, dioxolane, benzofuran, and chalcone groups is described

New Methods in the Synthesis of (Meth)Acrylamides and Application Chelating Resin for Determination of Trace Metals in Certified Reference Materials and Waters

The waste of trace metals are led the pollutions of water, soil and air. That’s why the accurate and sensitive identification of amount of trace metals in food samples and environment are gained importance in analytical chemistry because of their toxicity to human health. Besides, the direct determination of trace metals, presented at very low concentration especially in real samples, is difficult. In this content, before determination of trace metals by instrumental methods can be achieved successfully using separation/preconcentration procedures. The different synthesized chelating polymer resin adsorbents are successfully used for the SPE of trace metals. The trace metals, such as Cu, Cr, Co, Mn, Zn and Fe, are necessary for human health, when it has been taken at certain limits. But, the trace metals, such as Hg, Cd, Pb, Ni and As are toxic metals for the human body. About this, there are studies on the determination of trace elements and mineral in food samples and environment. In this study, new methods in the synthesis of (meth)acrylamides and use as a sorbent in the trace metals extraction was identified
