The electronic stopping cross section (SCS) of Al2O3 for proton beams is studied both experimentally and theoretically. The measurements are made for proton energies from 40 keV up to 1 MeV, which cover the maximum stopping region, using two experimental…

Thermoplastic polyurethane (TPU) adhesives containing nanosilicas with different specific surface area and silanol group content were prepared and characterized by FTIR spectroscopy, differential scanning calorimetry (DSC), thermogravimetry (TGA), X-ray diffraction, plate-plate rheology, dynamical–mechanical–thermal analysis (DMTA), transmission electron microscopy (TEM), and…

A procedure to increase the adhesion of block styrene–butadiene–styrene (SBS) rubber consisting of the reactive grafting with maleic anhydride (MA) in the presence of an organic peroxide radical initiator is proposed. The influence of the reactive grafting on the surface…

The hardest part of coaching work is the psychological preparation of athletes and gymnasts, where the aim is to achieve higher performance. Motivation – as the driving force of our actions – has an increased role in preparing the gymnasts,…

Objective: Although the relationship between area socioeconomic environment and obesity is known, previous research has measured area socioeconomic environment at only one point in time. This study evaluates the relationship of cumulative area-based adverse socioeconomic environment with body mass index…

Fecal samples from the Siberian tiger (Panthera tigris altaica)
and the Amur cat (Felis bengalensis euptilurus) from Far Eastern
Russia, were examined for parasites. A natural sedimentation methodology
was used and a complete examination of all the sediment was
performed.…

Web designers usually ignore how to model real user expectations and goals, mainly due to the large and heterogeneous audience of the Web. This fact leads to websites which are difficult to comprehend by visitors and complex to maintain by…

The electroreflectance (ER) technique has been applied to the study of the electrooxidation of some simple amino acids (glycine, serine and alanine) on a Pt(111) surface in acid medium. A different behaviour in the (1:R)(#R:#E) response as a function of

Accurate approximate closed-form solutions for the cubic-quintic Duffing oscillator are obtained in terms of elementary functions. To do this, we use the previous results obtained using a cubication method in which the restoring force is expanded in Chebyshev polynomials and…

Seventy-five years ago, Walter Benjamin showed us that the line between "production" and "reproduction" had begun to blur. Reproduction was no longer optional, consequential and degrading (the shredding of the original’s aura), but was instead being transformed into a principle…
