It was found by scanning electron microscopy method that the ZrMn0.5Ni1.2Cr0.18А0.1 alloy has a dendritic structure, and the shooting of a typical section of the surface of the metalographic sample in characteristic rad...

Context. The star V426 Sge (HBHA 1704-05), originally classified as an emission-line object and a semi-regular variable, brightened at the beginning of August 2018, showing signatures of a symbiotic star outburst. Aims. ...

In this study, WTaNbMo refractory high-entropy alloy (RHEA) coatings were successfully fabricated on Inconel 718 substrate by laser cladding. Optimal coatings with superior comprehensive performances were systematically ...

A new numerical model to describe the microstructural evolution of a eutectic nodular cast iron during its cooling is presented. In particular, equiaxial solidification assuming an independent nucleation of austenite and...

One way to understand ecological patterns of species is to determine their physiological diversity on a large geographic and/or temporal scales, in a context of hierarchical biodiversity framework. In particular, macroph...

Context. Pulsars have an overall very stable rotation. However, sudden increases in their rotation frequency, known as glitches, perturbtheir evolution. While many observatories commonly detect large glitches, small glit...

Abstract This study examines the European distribution of Chinese foreign direct investment (FDI), with a particular focus on the influence of cultural distance alongside structural and institutional factors. Employing a...

Optical trapping and manipulation using focused laser beams has emerged as a powerful tool in the biological and physical sciences. However, scaling this technique to metallic nanoparticles remains challenging due to the...

Abstract Background Society aims for a pollutant-free environment, reflected in initiatives under the European Green Deal, which seek to reduce hazardous substances and promote safe, sustainable chemical use. Comprehensi...

High accuracy of results is a very important aspect in any clustering problem t determines the effectiveness of decisions based on them. Therefore, literature proposes methods and solutions that aim to give more accurate...

Documentation of avian diversity is an effective method to monitor the quality of a habitat, along with long-term effects of habitat fragmentation, developmental activities, and urbanization. In the current investigation...

There are always a few economic policy targets to be achieved at a given time. Politicians always strive to simultaneously achieve the optimal size for each of them. However, these targets are always at least partly cont...

Whether we call them local production systems, clusters or industrial districts, all of these co-opetition arrangements can be considered stimuli in developing and implementing innovations as well as local and regional g...
