The Lerch Zeta and Related Functions of Non-Positive Integer Order
(Proceedings of the American Mathematical Society, 2010)
It is known that the Lerch (or periodic) zeta function of non-positive integer order, l(-n)(xi), n is an element of N(0) := {0, 1, 2, 3, ...}, is a polynomial in cot(pi xi) of degree n+1. In this paper, a very simple ...
Determination of Surface Properties of Various Oxides and Sulfides by Inverse Gas Chromatography
(Materials and Manufacturing Processes, 2009)
The surface properties of various oxides (ZrO(2) and Fe(3)O(4)) and sulfides (HgS and FeS) were investigated by the inverse gas chromatography method (IGC). The retentions of several organics were measured in the temperature ...
Correlation between lipophilicity of the ligands and the hepatobiliary properties of the radiopharmaceuticals: Approach to the development of new IDA derivatives
(Journal of Radioanalytical and Nuclear Chemistry, 2000)
The partition coefficient (log P) for n-octanol/water system was calculated applying PACO program for various theoretically possible mono and dihalogenated IDA derivatives. Some of the synthesized ligands (SOLCOIODIDA, ...
Be-7 in atmospheric deposition: determination of seasonal indices
(Journal of Radioanalytical and Nuclear Chemistry, 2015)
This paper is focused on the results for activity concentrations of Be-7 in depositions recorded in Vina Institute of Nuclear Sciences, as part of radioactivity monitoring in Institute from 1994 to 2013. year. Samples were ...
Effects of 200 keV Ar-ions irradiation on the structural and optical properties of reactively sputtered CrN films
(Optical Materials, 2016)
Modification in structural and optical properties of chromium-nitride (CrN) films induced by argon ion irradiation and thermal annealings were investigated using various experimental techniques. CrN films deposited by d.c. ...
Antimicrobials: a global alliance for optimizing their rational use in intra-abdominal infections (AGORA)
(World Journal of Emergency Surgery, 2016)
Intra-abdominal infections (IAI) are an important cause of morbidity and are frequently associated with poor prognosis, particularly in high-risk patients. The cornerstones in the management of complicated IAIs are timely ...
Composite localized modes in discretized spin-orbit-coupled Bose-Einstein condensates
(Journal of Physics. B: Atomic Molecular and Optical Physics, 2015)
We introduce a discrete model for binary spin-orbit-coupled Bose-Einstein condensates trapped in a deep one-dimensional optical lattice. Two different types of the couplings are considered, with spatial derivatives acting ...
A mathematical model of stress reaction: Individual differences in threshold and duration
(Psychobiology, 2000)
People differ in what they experience as stressful and to what extent. We define a variable-stress threshold (sigma)-that links the hypothalamo-pituitary-adrenocortical (HPA) axis and the memory system in a feedback ...
Assessment of residual stresses and mechanical characterization of materials by hole drilling and indentation tests combined and by inverse analysis
(Mechanics Research Communications, 2015)
Hole Drilling (HD) tests are frequently employed as quasi-non-destructive experiments, for assessments of residual stresses in metallic components of power plants and of other industrial structures. With respect to the ...
Measurement of radioactivity in building materials in Serbia
(Journal of Radioanalytical and Nuclear Chemistry, 2015)
This work presents a comprehensive study of natural radioactivity in 720 building materials imported in Serbia in 2012. Radioactivity concentrations of Ra-226, Th-232 and K-40 in the studied samples range from LT 5 to ...
