Physiological abnormalities resulting from death of dopaminergic neurons of the central nervous system in Parkinson's disease also extend to the retina, resulting in impaired visual functions. In both parkinsonian patients and animal models, low levels of dopamine and loss of…

Phylogenetic relationships within Limonium (Plumbaginaceae) are evaluated using sequence data from three plastid regions (rbcL, the trnL intron, and the trnL-trnF intergenic spacer). Sixty-six species representing the major genera of Staticoideae, including representatives of all sections and genera formerly included…

Numerical calculation of Fresnel patterns through fast Fourier transforms usually requires an extremely large number of samples in order to fulfil the Nyquist sampling condition. In many applications, the cut-off frequency of the system is much below the limit fixed…

Energy storage technologies provide an alternative solution to the problem of balancing power generation and power consumption. Redox flow cells are designed to convert and store electrical energy into chemical energy and release it in a controlled fashion when required.…

A new microwave assisted desolvation system based on the use of a TM010 cavity (MWDS2) has been developed and evaluated in plasma based analytical techniques: inductively coupled plasma atomic emission spectrometry (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS). The…

This paper presents recent advances in the areas of modeling, design, and fabrication of microwave filters for space applications. A fast and accurate hybrid analysis method, combining boundary integral resonant mode expansion (BI-RME) and integral equation (IE) techniques, is described.…

Obtaining holographic volume gratings with high diffraction efficiencies that can be used under white light has been a serious problem for the polyvinyl alcohol-acrylamide-based photopolymers developed by other researchers. In this paper we propose to eliminate the residual monomer in…

"El muchacho que se haya habituado a rechazar de forma instintiva toda trampa en un campeonato juvenil ha adquirido un modo de ser de fecunda dimensión social. Con muchos hombres así se puede llegar lejos" Cagigal (1966:371).

In this paper we study the distribution of the zeros of each function G_{n}(z)≡1+2^{z}+...+n^{z}, n≥2, which approaches the Riemann zeta function for Rez<-1, and is closely related to the solutions of the functional equations f(z)+f(2z)+...+f(nz)=0. We determine the density of…

China’s growing economic importance has led to a significant increase in the volume of empirical research about business and management in this country during the last few years. This study reviews the 180 empirical papers focusing on the Chinese context…
