On the spectrum of the Rhaly operators on c(0) and c
(INDIAN NAT SCI ACAD, 1998)In this paper, we determine the spectrum of the Rhaly matrix R-a as an operator on the spaces c(0) and c, when lim(n) (n + l)a(n) not equal 0 and exists. -
On the spectrum of the Rhaly operators on l(p)
(INDIAN NAT SCI ACAD, 2001)In 1989, Rhaly determined the spectrum of R-alpha, the Rhaly operator which is represented by the matrix : [GRAPHICS] regarded as an operator on the Hilbert space iota (2) normed by parallel to x parallel to = (Sigma (n) ... -
On the Use of Conventional and Soft Computing Models for Prediction of Gross Calorific Value (GCV) of Coal
(TAYLOR & FRANCIS INC, 2011)Gross calorific value (GCV) is an important characteristic of coal and organic shale; the determination of GCV, however, is difficult, time-consuming, and expensive and is also a destructive analysis. In this article, the ... -
On the value of dolines in gypsum terrains as a "Geological Heritage": an example from Sivas basin, Turkey
(SPRINGER, 2012)Karst topography is a landscape shaped by the dissolution of a layer or layers of soluble bedrock, usually limestone and evaporites. Karstification in the Sivas basin (Turkey) has sculpted a beautiful landscape with a ... -
On Topological Structures of Fuzzy Parametrized Soft Sets
(HINDAWI PUBLISHING CORPORATION, 2014)We introduce the topological structure of fuzzy parametrized soft sets and fuzzy parametrized soft mappings. We define the notion of quasi-coincidence for fuzzy parametrized soft sets and investigated its basic properties. ... -
On trace of symmetric bi-gamma-derivations in gamma-near-rings
(UNIV HOUSTON, 2007)Let M be a 2-torsion free 3-prime left Gamma-near-ring with multiplicative center C. For x is an element of M, let C(x) be the centralizer of x in M. The aim of this paper is to study the trace of symmetric bi-Gamma-derivations ... -
On upper and lower D*-supercontinuous multifunctions
(AKADEMIAI KIADO, 2007)We define a multifunction F: X -> Y to be upper (lower) D*-supercontinuous if F+(V) (F-(V)) is d*-open in X for every open set V of Y. We obtain some characterizations and several properties concerning tipper (lower) ... -
Onychomadesis: A New Side Effect of Sodium Valproate Therapy in Children?
(GALENOS YAYINCILIK, 2011)Valproic acid has been widely used for the treatment of epilepsy. Although usually well-tolerated, it has been associated with some side effects. Nail abnormalities are rare side effects of valproic acid. Onychomadesis ... -
Open-label, prospective, randomized comparison of propofol and sevoflurane for laryngeal mask anesthesia for magnetic resonance imaging in pediatric patients
(ELSEVIER, 2008)Background: Magnetic resonance imaging (MRI) for pediatric patients often requires deep sedation or anesthesia because they must remain completely immobile for a relatively long period to obtain high-quality images. ... -
