Chemical and biological properties of verapamil labeled with technetium-99m: A potential myocardial imaging agents
(Journal of Radioanalytical and Nuclear Chemistry, 2002)
On the base of property to enter into myocardial cells as a calcium channel blocker, verapamil was labeled with technetium-99m in order to investigate the possibility to obtain new radiopharmaceutical for myocardial imaging. ...
Reflected radiation assessment in contrast X-ray diagnostics
(Radiation Physics and Chemistry, 2004)
Introduction
In X-ray diagnostics, a quantitative assessment of medical staff exposure is essential for radiation protection measures. A good knowledge of the space-energy distribution of scattered radiation around a ...
Closed-form summations of certain hypergeometric-type series containing the digamma function
(Journal of Physics. A: Mathematical and Theoretical, 2008)
Recently, interesting novel summation formulae for hypergeometric-type series containing a digamma function as a factor have been established by Miller (2006 J. Phys. A: Math. Gen. 39 3011 - 20) mainly by exploiting already ...
Stress relaxation in hematite nanoparticles-polystyrene composites
(Macromolecular Rapid Communications, 2000)
The viscoelastic behavior of a polystyrene matrix filled with hematite nanoparticles was investigated using the stress relaxation method. An increase in the elastic moduli of the composites, as well as in the magnitude of ...
Closed-form formulae for the derivatives of trigonometric functions at rational multiples of pi
(Applied Mathematics Letters, 2009)
In this sequel to our recent note [D. Cvijovic, Values of the derivatives of the cotangent at rational multiples of pi, Appl. Math. Lett. http://dx.doi.org/10.1016/J.aml.2008.03.013] it is shown, in a unified manner, by ...
Detection of Adducts with Matrix Clusters in the Positive and Negative Ion Mode MALDI-TOF Mass Spectra of Phospholipids
(Zeitschrift fur Naturforschung. Section B: Journal of Chemical Sciences, 2009)
It is usually accepted that neutral phospholipids (PLs) generate singly positively charged ions, whereas negative PLs are easily detectable in the negative ion mode when analysed by matrix-assisted laser desorption and ...
Synthesis, structural and luminescent properties of Gd2O3-SiO2 : Eu3+ nanopowder composites
(Materials Science Forum, 2006)
In view of the improvement of luminescent intensity in classical phosphors, different new techniques of synthesis have been developed. One of them is the sol-gel technique for nanopowder synthesis. Applied to a binary ...
Biphonons in the beta-Fermi-Pasta-Ulam model
(Physica. D: Nonlinear Phenomena, 2006)
Discrete breathers or intrinsic localized modes are nonlinear localized states that appear in several classical extended systems, such as for instance the Fermi-Paste-Ulam (FPU) model. In order to probe the quantum states ...

Theoretical assessment of phosphate amendments for stabilization of (Pb plus Zn) in polluted soil
(Waste Management, 2009)
Contamination of the environment with toxic metals, such as lead (Pb), represents a serious concern for human health. Most of the studies on Pb stabilization were performed using various phosphorus-containing amendments ...
