logical progress. Global development, however, raises new challenges, especially in the field of environmental protection and conservation. Technological ingenuity has enhanced the potential for improving industrial development and rapid progress is being made not only in the field of electronics but also in biological, medical and pharmaceutical applications. In recent decades, increasingly pr...

EDITORIAL SYNOPSIS The results of a retrospective analysis of the records of 665 consecutive patients with diffuse peritonitis emphasize the considerable effect age and causal lesion have on the prognosis. The comparison of results of any innovations in the treatment of diffuse peritonitis cannot he assessed unless these factors are fully taken into account. The fallacy of comparing overall mor...

While subsurface scattering is common in many real objects, almost all separation algorithms focus on extracting specular and diffuse components from real images. In this paper, we propose an appearance-based approach to separate non-directional subsurface scattering reflectance from photometric images, in addition to the separation of the off-specular and non-Lambertian diffuse components. Our...

Aim of this study is to review the methods used to determine hemoglobin non invasively while many conventional devices and techniques are available for measurements readily in the market. This paper discusses the advantage of non invasive measurement specifically focusing on techniques like pulse oximeter, occlusion spectroscopy, opto acoustic method, diffuse reflectance spectroscopy and the de...

Computing irradiance analytically from polygonal luminaires in polygonal environments has proven effective for direct lighting applications in diffuse radiosity environments. Methods for analytic integration have traditionally used edge-based solutions to the irradiance integral; our previous work presented a vertex-based analytic solution, allowing irradiance to be computed incrementally by ra...

Detection of highlights is a prominent issue in computer vision, graphics and image processing. Applications which require object properties measurement or rendering are affected by specular reflection since the models assume matte diffusing surfaces most of the time. Hence, detection, and sometimes removal, of specular reflection (highlights) in an image may be critical. Several methods are pr...

We consider thin liquid layers which completely wet nonideal (either rough or heterogeneous in composition) solid surfaces. Two different sources of fluctuations of the liquid surface are identified, and the competition between them is investigated. For thick enough films (but still in the submicrometer range), the liquid surface fluctuations are dominated by thermally induced capillary waves. ...

In 16 infants with intractable diarrhoea, latent otomastoiditis was found in 9 (3 at necropsy and 6 at myringotomy-antrotomy). In 5 of the 6 operated group, surgery was followed by a striking cessation of the diarrhoea and with weight gain. It is concluded that (1) latent otomastoiditis may be a perpetuating factor in intractable diarrhoea; (2) myringotomy-antrotomy should be considered if othe...

Far-UV observations in and near the Hubble Deep Fields demonstrate that the Space Telescope Imaging Spectrograph (STIS) can potentially obtain unique and precise measurements of the diffuse far-ultraviolet background. Although STIS is not the ideal instrument for such measurements, high-resolution images allow Galactic and extragalactic objects to be masked to very faint magnitudes, thus ensuri...
