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…

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…

Aim. This paper is a report of a study conducted to identify the conditions that favour the relief of the burden of female caregivers of relatives with advanced dementia. Background. Respite services are a response to caregivers’ needs for rest.…

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…

The human eye is a complex dynamic system that undergoes fine rotations and deformations. Usually information about the eye globe deformation and micromovements are averaged and lost when using commercial measuring devices, although they provide important information about the eye’s…

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…

Surfaces with radial structure do not fit well to squared detectors or sampling matrices. Cartesian grid sampling provides a different density of nodes in sectors. Zernike polynomials are a complete set of orthogonal polynomials defined on a unit disk often…

Spontaneous eye blinking is a complex process, which implies the joint actions of the eyelid muscles and the eye globe. These actions provoke the eyelid closure and simultaneous eye retraction into the orbit. Recently, the authors presented a non-invasive technique…

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…
