Large scale fire tests and observations of actual building fires have shown that the fire performance of composite steel framed buildings is much better than is indicated by fire resistance tests on isolated elements. This contribution presents application of a simple design method, so-called FRACOF concept, for the analysis of non sway steel framed buildings with composite floors. Starting point were the outstanding results obtained in the BRE Cardington large scale building fire test programme carried out during 1995 and 1996. The method was further validated by large-scale standard furnace tests in 2008 and 2009, as well as with natural fire tests in 2010. A recent test has also shown the possibility of application of this concept to composite floors with castellated beams. The recommendations are in line with the reliability level imposed by current design rules and are limited to structures similar to that tested. The method permits designers to spare the fire protection for the framing elements for which it is not needed by keeping the same safety requirement than traditional codes. [less ▲]

The thermodynamic method for fractal analysis is applied to mercury intrusion data. The results for representative commercial carbon black samples and a series of resorcinol-formaldehyde (RF) freeze-dried gels for different values of the molar ratio of resorcinol (R) to catalyst (C) are discussed in relation with the type of behavior exhibited by the samples during mercury porosimetry measurements. The obtained surface fractal dimensions are compared with those derived previously from the small-angle X ray scattering (SAXS) and the nitrogen adsorption. Copyright 1999 Academic Press. [less ▲]

Fractal analysis has been applied to characterize the structure of Pd-Ag/SiO2 catalysts dried under vacuum (150 degrees C and 12 hPa) with different concentrations of Pd-Ag, Nitrogen adsorption-desorption, mercury porosimetry, and small-angle X-ray scattering measurements have been used. The different approaches to fractal analysis and their conditions of applicability are briefly described. Results are discussed in relation to those derived previously from classical interpretations. This analysis shows that Pd-Ag/SiO2 xerogels exhibit a very open self-similar pore structure analogous to the structure of supercritically dried aerogels and that the micropore texture can be tailored by varying the silver content.

Evidence of fractal grain boundaries is found in polycrystals when radial patterns are found to result from a geometrical competition between different grains that have nucleated on the same center. A simple statistical model presented herein predicts the universal fractal dimension 2.33 of such natural patterns grown through internal competition. The application to material patterns having constrained front propagation involving many components is obvious. [less ▲]

Using two different methods, we compute the fractal dimension of the power spectrum associated with numerical solutions of the spatially homogeneous Bianchi IX cosmological model in Misner-Chitre coordinates. According to Perdang's criterion, the noninteger character of this dimension is reflection of chaos and can be used to measure it, in the same spirit as the Lyapunov exponent of the Kolmogorov entropy. The results obtained indicate the chaotic nature of the behaviour of the Bianchi IX model near the cosmological singularity. [less ▲]

BACKGROUND: Recent advances in angiogenesis research have led to the introduction of new prognosis factors. Although the vessel count is effective in breast cancer, the prognosis of primary cutaneous melanoma (PCM) does not seems to be directly influenced by this parameter. However, the microscopic examination of PCM suggests variability in the repartition of the microvasculature. OBJECTIVE AND METHOD: To explore the possibility of extracting information about the vessel distribution by performing a textural analysis on the grey level of histological sections by means of fractal characterization by both Fourier spectrum and multifractal analysis. RESULTS: Three different patterns of vasculature were identified according to the vessel density and distribution. CONCLUSION: It is possible to differentiate and quantify clearly the differences in the microvessel profile organization using the fractal and multifractal methods. [less ▲]

For the overall calibration and validation of the AquaCrop model decent information on the development of the canopy cover is crucial. Throughout the growing season overhead canopy pictures were taken. Different image treatment programs have been evaluated on their capacity to retrieve the fractional cover data from these images. The findings are presented in this technical note. The objectives (and/or constraints) were manifold: - determine for each image the percentage of canopy cover of the monitored crop (maize or cabbage); - in case of mixed-cropping, calculate a separate canopy cover for each crop; - weeds are to be excluded; - mask all non-desired items (camera operator, field borders, …).

This study addressed the potential radiosensitizing effect of nicotinamide and/or carbogen on human glioblastoma xenografts in nude mice. U-87MG and LN-Z308 tumors were irradiated with either 20 fractions over 12 days or 5 fractions over 5 days in air-breathing mice, mice injected with nicotinamide, mice breathing carbogen, or mice receiving nicotinamide plus carbogen. The responses to treatment were assessed using local control and moist desquamation. In U-87MG tumors, the enhancement ratios (ERs) at the radiation dose required to produce local tumor control in 50% of the treated mice (TCD50) with nicotinamide and/or carbogen ranged from 1.13 to 1.24 for irradiation in 20 fractions over 12 days. In LN-Z308 tumors, the ERs at the TCD50 with nicotinamide and/or carbogen ranged from 1.22 to 1.40 for irradiation in 5 fractions over 5 days and from 1.11 to 1.30 in 20 fractions over 12 days, respectively. Skin injury was slightly enhanced, with ERs ranged from 1.06 to 1.15 when radiation was combined with carbogen and/or nicotinamide. Thus carbogen and nicotinamide can slightly improve the radiation response of human glioblastoma xenografts. [less ▲]
