Combining dissimilar parts has become imperative for developing the structures based on lightweight materials, such as metal alloys, polymers or polymer matrix composites, and this one of solutions to reverse current trend CO2 emissions in transport sector. However, given usual property disparities, joining materials multi-material multi-purpose raises new engineering challenges. Advanced proce...

The article is devoted to the description of developed automated design system for vibration-frequency density meters with a demonstration wide functionality program and interface settings. development solves problem designing meters, calculating quality factor sensitivity resonators, which provide dependence frequency self-oscillations on controlled density. lack clear methodological recommend...

The responsible and sustainable use of energy in private, public and business environments is one of the major societal challenges of our time. An essential part of this challenge is to increase the energy efficiency of (high energy) companies and implementing a sustainable energy management. In this paper we demonstrate that this is a complex socio-technical problem that asks for a holistic vi...

Fastening is a recurrent assembly operation at the aerospace industry. Among many different types of fasteners being used blind ones offer particular advantages but there yet lack reliable installation monitoring methods for their massive adoption. The present paper proposes an evaluation solution that integrates effect previous drilling and allows visualization relationships between hole quali...

Concentration and properties of free radicals in the burn wounds treated with propolis were examined by the use of electron paramagnetic resonance spectroscopy. Magnetic spin-spin interactions and complex free radicals structures in wound beds were studied. The results were compared to those obtained for silver sulphadiazine used as a standard pharmaceutical agent. The changes of free radicals ...

As an aging society approaches, the issue of injuries from falls by the elderly has emerged anew. Because of the dangers involved, research has recently been conducted on various types of falls; in particular, considerable research has been carried out on the detection and prevention of falls. We design an algorithm for the detection of falls using smartphones equipped with three-axis accelerom...

Parallel and distributed systems archi tectures support parallel I O components Caching has been applied to distributed I O subsystems as a standard solution to the problems of fastening data accessibility and increasing data reliability Cache consistency mechanisms have been implemented in order to in uence the cache usefulness in a posi tive way This paper presents a new caching tech nique ba...

A biocompatible amine functionalized fluorescent carbon dots were developed and isolated for gram scale applications. Such carbogenic quantum dots can strongly conjugate over the surface of the chloroplast and due to that strong interaction the former can easily transfer electrons towards the latter by assistance of absorbed light or photons. An exceptionally high electron transfer from carbon ...

Tooth bleaching has become a popular cosmetic treatment among patients that want to enhance their esthetic appearance. In addition, light-activated bleaching gels have been growing among dental professionals mainly due to the fastening of the whitening procedure and/or therapeutic purposes. Thus, the objective of this case report was to present the bleaching protocol and efficacy of a light-act...
