In the triathlon the combined practice of swimming, cycling and running permits the reduction of overuse injuries compared to the practice of the running alone. Redistribution of stress over several part of the body and correction of muscle imbalance are…

This paper mainly concerns the study of a large class of variational systems governed by parametric generalized equations, which encompass variational and hemivariational inequalities, complementarity problems, first-order optimality conditions, and other optimization-related models important for optimization theory and applications. An…

Fianoniella stenognatha sp. n. from the Columbretes Islands (Castellón, Spain) is described and illustrated. The new species is distinguished by its longer and narrower mandibles with parallel or divergent rims in the apical half, wider clypeus, hind ocelli more separated…

In this paper, we extend our previous light microscopic (LM) study of substance P (SP)-containing amacrine and ganglion cell types of the human retina (Cuenca et al. [1995] J. Comp. Neurol. 356:491–504) to an electron microscopic (EM) and confocal-imaging study…

A grounded theory study was undertaken to gain insight into the processes underpinning health visiting. It was found that health visitors introduce their services into the client domain via a process constructed in this study as ‘marketing’. This process involves…

In this work, we have applied the fractional Fourier transform to obtain the Fresnel diffraction patterns in a theoretical eye. The FRT approach to Fresnel diffraction is easily implemented in a Gullstrand-Emsley theoretical eye, and it allows us to obtain…

Photographic emulsions are still widely used to record holographic optical elements. In particular, if high diffraction efficiencies are needed, phase volume holograms are preferably recorded on these emulsions. Two particular techniques producing high-quality volume phase holograms are fixation-free rehalogenating bleaching…

We report for the first time the results of a comparative performance study of silver-halide sensitized gelatin (SHSG) holograms recorded in the familiar Agfa 8E75 HD plates and the new BB-640 plates manufactured by Holographic Recording Technologies. High diffraction efficiency…

Silver halide sensitized gelatin (SHSG) is one of the most promising techniques for the fabrication of transmission holographic optical elements, achieving relatively high sensitivity of photographic material with the low scattering and high light stability of dichromated gelatin. In this…

This paper describes two in vitro regeneration systems through direct and indirect organogenesis in Pinus brutia using fascicles aseptic cultures as explants. Mechanical scarification and gibberellic acid (GA3) were evaluated on in vitro seed germination. Scarification was the treatment that…
