Isobolographic analysis provides a fundamental basis for assessing whether biological responses induced by mixtures of agents are greater, equal or smaller than would have been expected on the basis of the individual activities of the component agents and the concept of dose additivity. Limited in its direct application to binary mixtures, isobolographic analysis provides a conceptual framework...

PHOTOGRAPHY WITH INFRA-RED FILM Dekking (1933, 1934) published several photographs of eyes with dense corneal opacities using infra-red film and radiation of a wave-length of about 10,000 A.u. His photographs strikingly demonstrated how infra-red radiation could penetrate a dense corneal opacity, and clearly record the appearance of the iris and pupil, which were invisible by ordinary methods o...

BACKGROUND Vascular calcification is a common finding in abdominal aortic aneurysms (AAA) however whether it predicts aneurysm expansion is controversial. OBJECTIVES 1) To establish a reproducible method of assessing AAA calcification using computed tomography (CT); 2) To investigate the association between AAA calcification and growth. METHOD Patients were identified from a prospectively m...

Patients with syndromic craniosynostosis suffering from shallow orbits due to midface hypoplasia can be treated with a Le Fort III advancement osteotomy. This study evaluates the influence of Le Fort III advancement on orbital volume, position of the infra-orbital rim and globe. In pre- and post-operative CT-scans of 18 syndromic craniosynostosis patients, segmentation of the left and right orb...

Observations in the submillimetre waveband have recently revealed a new population of luminous, sub-mm sources. These are proposed to lie at high redshift and to be optically faint due to their high intrinsic dust obscuration. The presence of dust has been previously invoked in optical galaxy count models which assume τ = 9 Gyr Bruzual & Charlot evolution for spirals and these fit the count dat...

Until now only for special classes of infra-solvmanifolds, namely, infra-nilmanifolds and infra-solvmanifolds type (R), there was a formula available computing the Nielsen number self-map on those manifolds. In this paper, we provide general averaging which works all self-maps possible reduces to old formulas in case or (R). Moreover, when viewing an infra-solvmanifold as polynomial manifold, r...

Figure 1 shows an infra-red spectrum gathered by a satellite looking down towards the Earth from around 20km. This spectrum shows the intensity of emission plotted against frequency (wavenumber). The energy depicted is mostly radiated from the surface of the Earth, which is almost a perfect blackbody and radiates radio waves in the infra-red frequency band. The imperfections in the shape of the...
