NORMAL DEVELOPABLE SURFACES OF A SURFACE ALONG A DIRECTION CURVE
(Indonesian Mathematical Soc, 2020)We construct a developable surface normal to a surface along a curve on the surface. We choose the curve as the normal direction curve on which the new surface is formed in Euclidean space. We obtain some results about the ... -

A Note on the Structure of Certain Real Quadratic Number Fields
(Springer International Publishing Ag, 2017)The aim of this paper is to determine the general forms of the continued fraction expansions of the quadratic irrational number w(d) which is integral basis element of Z [1+root d/2] also determine t(d); u(d) which are the ... -
A novel approach to Chromium rejection from sewage wastewater by pervaporation
(Elsevier, 2021)Pervaporation is an effective method, especially in the separation of azeotropic mixtures or in the recovery of some components from the mixtures. Although various methods have been used for the treatment of chromium-containing ... -
Novel dendrimers containing redox mediator: Enzyme immobilization and applications
(Elsevier Science Bv, 2019)In this study, new dendrimers with a ferrocene core were produced by means of a divergent method for the immobilization of the glucose oxidase enzyme (GOx). Pt(II) and Pt(IV) ions were attached to the terminal groups of ... -

(Elsevier Science Sa, 2015)Two novel phthalonitriles,7-(2,3-dicyanophenoxy)-3-(3,5-difluorophenyl) coumarin (2), 7-(3,4-dicyanophenoxy)-3-(3,5-difluorophenyl) coumarin (3), and corresponding zinc(II)-, indium(III) phthalocyanines were prepared. ... -
Novel polymeric microspheres: Synthesis, enzyme immobilization, antimutagenic activity, and antimicrobial evaluation against pathogenic microorganisms
(Wiley, 2020)New polymeric microspheres containing azomethine (1a-1c and 2a-2c) were synthesized by condensation to compare the enzymatic properties of the enzyme glucose oxidase (GOx) and to investigate antimutagenic and antimicrobial ... -
Novel water soluble 7-oxy-4-(pyridine-3-yl) coumarin substituted phthalocyanines as potential photosensitizers for photodynamic therapy
(Elsevier Science Sa, 2019)The new phthalonitriles (1 and 2) and zinc, indium, magnesium metalled tetrasubstituted phthalocyanines bearing 7-oxy-4-(pyridine-3-yl) coumarin substituents in the peripheral (1a-c)/non-peripheral (2a-c) positions were ... -
On a variational problem due to the B-Darboux frame in Euclidean 3-space
(Wiley, 2021)In this paper, we introduce a new frame which is called the B-Darboux frame on a surface in Euclidean 3-space. We know that the parallel transport frame is derived from the Frenet frame along a space curve on a surface. ... -
On computing the degree of a Chebyshev Polynomial from its value
(Academic Press Ltd- Elsevier Science Ltd, 2021)Algorithms for interpolating a polynomial f from its evaluation points whose running time depends on the sparsity to f the polynomial when it is represented as a linear combination of t Chebyshev Polynomials of the First ... -
