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 ...

In the present paper we deal with nonlinear dynamics of microtubules. The structure and role of microtubules in cells are explained as well as one of models explaining their dynamics. Solutions of the crucial nonlinear ...

The paper presents an estimation procedure for the measurement of the thermal diffusivity of thermal barrier coatings deposited on thermal conductive substrates using the laser flash method when the thermal contact resistance ...

In a multipurpose cyclotron, it is convenient to use stripping extraction to extract selected positive ions in addition to the usual extraction by stripping of negative ions. The ions are specified as positive or negative ...

The effects of adsorption of boron containing molecules on the optical properties and reactivity of colloidal silver particles (4 nm diameter) were studied. The absorption spectra of silver particles surface modified by ...

The effects of negative charge on the optical properties of a silver sol prepared using sodium borohydride as a rcductant were studied. The oscillations ill the position of the maximum and the intensity of the surface ...

Numerous processes take place in materials under the action of concentrated energy flows. The most important ones include heating together with the temperature misdistribution throughout the depth, probable vaporization ...

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 ...
