A numerical study was carried out to examine the magnetohydrodynamic (MHD) flow of micropolar fluid on a shrinking surface in the presence of both Joule heating and viscous dissipation effects. The governing system of non-linear ordinary differential equations (ODEs) was obtained from the system of partial differential equations (PDEs) by employing...

A 58-year-old woman presented with acute pain in her back and her left leg. Magnetic resonance imaging (MRI) revealed an intradural schwannoma with an intratumoral hemorrhage between the lower L4 vertebra and L5/S1 disk level. A follow-up MRI after one month revealed that the tumor had regressed from the middle of L5 to the L5/S1 disk level. The tu...

AbstractThe choice of metal nanoparticles in the filling of anaerobic sealants is theoretically justified. The influence of metal nanoparticles on the polymerization process, as well as on the improvement of strength, endurance and heat conductivity of anaerobic sealant nanocomposites is described, as well.
Rapid climate and land-use changes have been considered as the foremost threat to global biodiversity. China contains more than 3500 threatened higher plants, whereas the relative influence of climate and land-use changes on these endangered plants have not been explored simultaneously under topographical constraints. Here, using Taxus plants as th...

In order to establish the kinetics of oxidation of artificial magnetite pellets, we comprehensively studied kinetics of the oxidation of artificial magnetite pellets from low temperature to high temperature using chemical analysis. The results show that when the oxidation temperature is below 1 073 K (800 °C), the reaction is controlled by the step...

Due to the general demographic situation in Hungary and the recent overall crisis of this traditional settlement-type, Hungarian small towns have been facing an intensive shrinking since the last decade. Although natural decrease and migration loss are almost equal factors of population decline, outmigration seems to be a more strategic, critical p...
Desde el cambio del milenio, el pib per cápita de los países en desarrollo ha crecido más rápido que el de los países desarrollados. Sin embargo, la pregunta acerca de si estos países en desarrollo han comenzado un proceso de convergencia con los países más ricos del globo se mantiene. La hipótesis de convergencia de ingresos cuestiona las fuentes ...

Hierarchically structured materials, inspired by sophisticated structures found in nature, are finding increasing applications in a variety of fields. Here, we describe the fabrication of wrinkled gold nanoparticle films, which leverage the structural tunability of gold nanoparticles to program the wavelength and amplitude of gold wrinkles. We have...
Cette position de recherche propose de transposer les cadres de la théorie spatiale de la diffusion des innovations à des phénomènes de rétraction en s’appuyant sur l’exemple de l’évolution de la répartition des services de soins dans le système urbain français. Les notions de concentration et de rétraction seront mobilisées pour explorer de manièr...
