#### 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 ...

#### Membrane Pertraction of Lu(III) with DEHPA as a Carrier and the Possibilities of Its Application for Purifying Lu-177-labeled Compounds

(European Journal of Nuclear Medicine and Molecular Imaging, 2009)

#### Evaluations of some classes of the trigonometric moment integrals

(Journal of Mathematical Analysis and Applications, 2009)

Four classes of the trigonometric moment integrals are evaluated in closed form in a simple and unified manner by making use of the contour integration in conjunction with the Cauchy integral theorem. In all cases, the ...

#### Psychosocial stress-related changes in gene expression of norepinephrine biosynthetic enzymes in stellate ganglia of adult rats

(Autonomic Neuroscience: Basic and Clinical, 2009)

In this study we investigated the changes in norepinephrine biosynthetic enzymes tyrosine hydroxylase (TH), dopamine beta-hydroxylase (DBH) and phenylethanolamine N-methyltransferase (PNMT) gene expression in the stellate ...

#### Values of the derivatives of the cotangent at rational multiples of pi

(Applied Mathematics Letters, 2009)

By elementary arguments, we deduce closed-form expressions for the values of all derivatives of the cotangent function at rational multiples of pi. These formulae are considerably simpler than Similar ones which were found ...

#### A dilogarithmic integral arising in quantum field theory

(Journal of Mathematical Physics, 2009)

Recently, an interesting dilogarithmic integral arising in quantum field theory has been closed-form evaluated in terms of the Clausen function Cl(2)(theta) by Coffey [J. Math. Phys. 49, 093508 (2008)]. It represents the ...

#### Comments on factors influencing the removal of divalent cations by hydroxyapatite Discussion

(Journal of Hazardous Materials, 2009)

Recently, Smicklas et al. [I. Smicklas, A. Onjia, S. Raicevic, Dj. Janackovic, M. Mitric, J. Hazard. Mater. 152 (2008) 876-884)] have reported on the effect of pH, contact time, initial metal concentration and presence of ...

#### In memory of Ljubomir Jovanovic (1935-2009)

(Thermal Science, 2009)

#### Summation formulae for finite cotangent sums

(Applied Mathematics and Computation, 2009)

Recently, a half-dozen remarkably general families of the finite trigonometric sums were summed in closed-form by choosing a particularly convenient integration contour and making use of the calculus of residues. In this ...

#### Structure of Disodium Dimolybdate Synthesized Using Thermodynamically Stable Molybdenum (VI) Oxide Clusters as Precursors

(Journal of the American Ceramic Society, 2009)

The structure of disodium dimolybdate (Na(2)Mo(2)O(7)) synthesized by a low-temperature method in the process of ultrasonic spray pyrolysis using acidified aqueous solutions of thermodynamically stable molybdenum (VI) oxide ...
