Obsidian outcrops from Nemrut volcano (eastern Anatolia): evidence in favor of an exploitable source, first results

Anne-Kyria Robin; Damase Mouralis; Catherine Kuzucuoglu; Ebru Akkopru; Bernard Gratuze; Ali Fuat Dogu; Erturaç, Mehmet Korhan; Joel Cetoute (GROUPE FRANCIAS GEOMORPHOLOGIE, 2015)

Archeological studies have demonstrated that many Prehistoric artefacts in obsidian found in the Near East have a chemical affinity with obsidian out-cropping in the Nemrut volcano. In the archaeological literature, Mount ...
OLPT CONDUCTIVITY IN WOLLASTONITE INLAID NR/SBR TYPE ELASTOMER BASED MATERIAL

Şentürk, Erdoğan; Demirer, Ahmet; Okur, İbrahim (UNIV CHEMISTRY & TECHNOLOGY, PRAGUE, 2012)

The electrical properties of wollastonite inlaid NR/SBR type elastomer based material have been evaluated. Electrical properties of the samples were measured in the temperature range of 303 to 453 K and the frequency range ...

In this paper, we give the characterization of some classes of compact operators given by matrices on the normed sequence space r(p)(q) (B-m), which is a special case or the paranormed Riesz B-m-difference sequence space ...
On Complex Fibonacci Quaternions

Halıcı, Serpil (SPRINGER BASEL AG, 2013)

Horadam defined the Fibonacci quaternions and established a few relations for the Fibonacci quaternions. In this paper, we investigate the complex Fibonacci quaternions and give the generating function and Binet formula ...

ON Delta-LACUNARY STATISTICAL ASYMPTOTICALLY EQUIVALENT SEQUENCES

Başarır, Metin; Altundağ, Selma (UNIV NIS, FAC SCI MATH, 2008)

This paper presents new definitions which are a natural combination of the definition for asymptotically equivalence Delta-lacunary statistically convergence. Using this definitions we have proved the S-theta(L) ...
On Fibonacci Quaternions

Halıcı, Serpil (BIRKHAUSER VERLAG AG, 2012)

In this paper, we investigate the Fibonacci and Lucas quaternions. We give the generating functions and Binet formulas for these quaternions. Moreover, we derive some sums formulas for them.
On generalized difference lacunary statistical convergence in a paranormed space

In this article, we introduce the concept of -lacunary statistical convergence and -lacunary strong convergence in a paranormed space. Also, we establish some connections between these concepts.
On Generalized Paranormed Statistically Convergent Sequence Spaces Defined by Orlicz Function

Başarır, Metin; Altundağ, Selma (HINDAWI PUBLISHING CORPORATION, 2009)

We define generalized paranormed sequence spaces (c) over bar(sigma, M, p, q, s), (c) over bar (0)(sigma, M, p, q, s) m(sigma, M, p, q, s), and m(0)(sigma, M, p, q, s) defined over a seminormed sequence space (X, q). We ...
