An objective approach to the definition of some mining terms: Application to the Hasançelebi iron ore deposit
(2004)In the mining industry, definitions of terms such as geologic resource, geologic reserve, mineral resource, mineral, mineral reserve, ore, ore reserve, mineable reserve, and industrial minerals always have been debated, ... -
Observations on Acanthamoeba trophozoites in axenic cultures and their staining characteristics with different stains [Aksenik kültürlerde Acanthamoeba trofozoitleri üzerindeki gözlemler ve bunlarin farkli boyalarla boyanma özellikleri.]
(2007)Acanthamoeba spp. are among the most prevalent protozoa found in the environment. The species of this genus are the causative agents of granulomatous amebic encephalitis (GAE), a fatal disease of the central nervous system ... -
Occult Hepatitis B Prevalence in Hepatitis B Vaccinated Dialysis Patients
(TURK NEFROLOJI DIYALIZ TRANSPLANTASYON DERGISI, 2018)OBJECTIVE: Occult hepatitis B (OHB) virus infection is defined as the presence of hepatitis B virus (HBV) DNA in the liver tissue or serum of subjects seronegative for hepatitis B surface antigen. OHB leads to the potential ... -
Occurrence and growth of lactic acid bacteria species during the fermentation of shalgam (salgam), a traditional Turkish fermented beverage
(ELSEVIER SCIENCE BV, 2012)Shalgam (salgam) is a traditional lactic acid beverage produced from the lactic acid fermentation of black carrot, turnip, rock-salt, sourdough, bulgur flour and drinkable water. The aim of this study was to examine ... -
Ocular and Genetic Characteristics Observed in Two Cases of Fish-Eye Disease
(LIPPINCOTT WILLIAMS & WILKINS, 2019)Purpose: To present ocular findings and anterior segment-optical coherence tomography (AS-OCT) imaging findings of 2 cases of fish-eye disease (FED) involving 2 novel genetic variants of the lecithin-cholesterol acyltransferase ... -
Ocular Findings in Patients with Crimean-Congo Hemorrhagic Fever
(ELSEVIER SCIENCE INC, 2009)PURPOSE: To describe ocular findings of patients with Crimean-Congo hemorrhagic fever (CCHF). DESIGN: Prospective, interventional, consecutive case series. METHODS: This study was conducted in Sivas, a city located in the ... -
Off-design flow measurements in a centrifugal compressor vaneless diffuser
(1995)Detailed measurements have been taken of the three-dimensional velocity field within the vaneless diffuser of a backswept low speed centrifugal compressor using hot-wire anemometry. A 16 percent below and an 11 percent ... -
Oil agglomeration of a lignite treated with microwave energy: Effect of particle size and bridging oil
(ELSEVIER SCIENCE BV, 2005)Oil agglomeration of Sivas-Divrigi (S-D) Uluayir lignite fines was carried out using kerosene and kerosene-extract oil (which was obtained from lignite treated with microwave energy) mixture as a bridging oil. The effects ... -
Oil recovery in rosehip seeds from food plant waste products using supercritical CO2 extraction
(ELSEVIER SCIENCE BV, 2016)Valuable oils in rosehip seeds produced as the solid waste during the process of marmalade production using seed-containing fruits were recovered by supercritical CO2 extraction method. The influence of the particle size ... -
omega-continuous multifunctions
(UNIV NIS, FAC SCI MATH, 2013)The purpose of this paper is to study omega-continuous multifunctions. Basic characterizations, preservation theorems and several properties concerning upper and lower omega-continuous multifunctions are investigated. ... -
On (*)-(sigma, T)-Lie ideals of (*)-prime rings with derivation
(HACETTEPE UNIV, FAC SCI, 2018)Let R be a (*)-prime ring with characteristic not 2, U be a nonzero (*)- (sigma, tau)-Lie ideal of R and d be a nonzero derivation of R. Suppose sigma, tau be two automorphisms of R such that sigma d = d sigma, tau d = d ... -
On (?, ?) derivations with module values [Modül de?erli? (? ?)-türevler üzeri?ne]
(1996)Let R be a ring, X ? (0) an R-bi-module, d : R ? Xa(a,r)- derivation with module value such that d? = ?d, d? = ?d and U ? (0) an ideal of R. Furthermore the following properties are also satisfied. For x ? X, a ? R xRa = ... -
ON (sigma, tau)-LIE IDEALS WITH GENERALIZED DERIVATION
(KOREAN MATHEMATICAL SOC, 2010)In the present paper, we extend some well known results concerning derivations of prime rings to generalized derivations for (sigma, tau)-Lie ideals. -
On a function of hyperconnected spaces
(Walter de Gruyter GmbH, 2007)In this paper, we introduce a new class of functions called contra R-maps which is contained in the class of regular set connected functions and contains (?, s)-continuous functions. Some characterizations of hyperconnected ... -
On a fundamental system of solutions of the matrix Schrodinger equation with a polynomial energy-dependent potential
(JOHN WILEY & SONS LTD, 2010)In this study in the interval (0;+infinity) a fundamental system of solutions with behavior at the neighborhood of zero and at infinity are investigated for the polynomial pencil of the matrix Schrodinger equation. The ... -
ON COMMUTATIVITY OF SEMIPRIME RINGS WITH GENERALIZED DERIVATIONS
(SCIENTIFIC PUBL-INDIA, 2009)Let R be an associative ring. An additive mapping f : R -> R is called a generalized derivation if there exists a derivation d : R -> R such that f (xy) f (x)y + xd(y), for all x, y E R. In this paper, we explore the ... -
On continuity of soft mappings
(2015)In this paper, we give some new characterizations of soft continuity, soft openness and soft closedness of soft mappings. We study restriction of a soft mapping and generalize the pasting lemma to the soft topological ... -
