Use of tire shreds in construction projects, such as highway embankments, is becoming an accepted way of beneficially recycling scrap tires. However, in the last decade there was a decline in the use of pure tire shreds as fill materials in embankment construction, as they are susceptible to fire hazards due to the development of exothermic reactions. Tire shred-sand mixtures, on the other hand...

Multifractal analysis techniques are applied to patterns in several abstract expressionist artworks, paintined by various artists. The analysis is carried out on two distinct types of structures: the physical patterns formed by a specific color (“blobs”), as well as patterns formed by the luminance gradient between adjacent colors (“edges”). It is found that the analysis method applied to “blob...

or centuries people have admired the flowF ing robes in works by such artists as Raphael and Michelangelo. The sculpted or painted folds of cloth not only demonstrate the artist’s technical skill but also reinforce the illusion of reality. The draping of virtual cloth is a challenge not only in art, but also in the generation of virtual worlds in computer science. Engineers, mathematicians, and...

In this study, MCM-41 mesoporous silica nanoparticles (NPs) and MCM-41÷Fe3O4 mesoporous silica NPs were prepared by sol-gel method using CTAB (cetyltrimethylammonium bromide) as template and TEOS (tetraethyl orthosilicate) as silica precursor in order to use these materials as drug delivery system (DDS) for different biologically active agents. The MCM-41 and MCM-41÷Fe3O4 mesoporous silica NPs ...

key words: 1064 nm dispersive Raman spectroscopy, pigment analysis, traditional red artists’ colorants Raman spectra of red colorants were obtained in-situ using a dispersive Raman microscope equipped with a 1064 nm laser source and InGaAs array detector. By employing nearIR excitation, the fluorescence of organic colorants is significantly reduced compared to visible wavelengths. Spectra prese...
