Model order reduction appears to be beneficial for the synthesis and simulation of compliant mechanisms due to computational costs. Model order reduction is an established method in many technical fields for the approximation of large-scale linear time-invariant dynamical systems described by ordinary differential equ…
The information given here is provided by the IMA Commission on New Minerals, Nomenclature and Classification for comparative purposes and as a service to mineralogists working on new species. Each mineral is described in the following format: Mineral name, if the authors agree on its release prior to the full descrip…
The manufacturing and physical properties of hot-melt adhesives are briefly reviewed. The effect of surface roughness on the adhesive properties of hot-melt seals have been studied based on the example of the technique for repairing automotive batteries.
Fluorescein isothiocyanate-conjugated bovine serum albumin (FITC-BSA)-loaded polyethylene glycol (PEG)-modified liposomes and lipoparticles with high protein entrapment were developed. The lipid formula of the liposomes contained PEGylated lipids and unsaturated fatty acids for enhancing membrane fluidity and effectiv…
BACKGROUND: We report here a unique approach to using multifunctional dendrimer/combretastatin A4 (CA4) inclusion complexes for targeted cancer therapeutics. METHODS: Amine-terminated generation 5 polyamidoamine dendrimers were first partially acetylated to neutralize a significant portion of the terminal amines, and…
The methodology for a heterodyned laser-induced transient thermal grating technique for non-contact, non-destructive measurements of thermal transport in opaque material is presented. Phase-controlled heterodyne detection allows us to isolate pure phase or amplitude transient grating signal contributions by varying th…
The conversion of solar power into electricity is dominated by non-concentrating photovoltaics and concentrating solar thermal systems. Recently, it has been shown that solar thermoelectric generators (STEGs) are a viable alternative in the non-concentrating regime. This paper addresses the possibility of STEGs being…
Compared with the conventional fixed speed drive, a major factor that handicaps the wide acceptance of variable speed drive with high efficiency permanent magnet (PM) motors is its high cost. This paper presents an effort to reduce the material and manufacturing costs of PM motors by using the soft magnetic composite…
The influence of accelerated water treeing test (AWTT) on the properties of 10 kV cross-linked polyethylene (XLPE) cable insulating materials was investigated in this paper. The dielectric and physicochemical properties of both aged samples and unaged samples were tested. Dielectric property investigation found a new…
Nanoparticles (NPs) have emerged as extremely promising materials to alter and improve the properties of liquid crystals (LCs) used, for example, in device applications. In this paper, we summarise recent work from our lab that aims to provide a fundamental understanding of structure–property and composition–property…
Surface charge decay on thick flat samples of HTV silicone rubbers charged by impulse corona is studied. In the experiments, surfaces of the materials exposed to corona were kept open to ambient air whereas the opposite surfaces were in contact with a grounded copper plate and surface potential distributions on the sa…
Two sets of non-symmetric chiral liquid crystal trimers have been synthesised and characterised. These consist of molecules containing a cholesteryl-based group, a 4-methoxyazobenzene unit and a central benzylideneaniline group, interconnected in a linear fashion via two flexible spacers. The length of the spacer conn…
Manufactured nanomaterials (NM) are already used in consumer products and exposure modelling predicts releases of ng to low µg l(-1) levels of NMs into surface waters. The exposure of aquatic ecosystems, and therefore fishes, to manufactured NMs is inevitable. This review uses a physiological approach to describe the…
BACKGROUND: Nanoparticles fabricated from the biodegradable and biocompatible polymer, polylactic-co-glycolic acid (PLGA), are the most intensively investigated polymers for drug delivery systems. The objective of this study was to explore fully the development of a PLGA nanoparticle drug delivery system for alternati…
It was demonstrated in our previous work that the combined carbon nanofibers (CNFs) and microsized short carbon fibers (SCFs) in epoxy (EP) leads to significant improvements in the mechanical properties of the matrix. In this work, the effect of nano-SiO2 particles, having an extremely different aspect ratio from CNFs…
The field research on building a rational subsystem of the operations and facilities for the efficiency upgrading of the combine harvester air-screen separator is resulted.
The research results of the social mythology of the modern Russian society are generalized. The typology of social myths is resulted. Some topical functions of the modern social mythology are considered. The correlation of the modern social mythology and ideology is analyzed.
Some tribo-thermodynamic hypotheses that permit to identify athermal and (or) thermal gripping, to define peak magnitude of the contact temperatures on the actual contact area of the wheel-rail tribo-system, are proved.
Some questions of the building and development of the students’ research competence in the course of their exploration and research activities are considered. The principal stages of the training research activities and methodic environment providing the development of thinking, as well as building the students’ resea…
The problem of the dynamic cutting system instability through the positional coupling which is formed as a result of the cutting force change depending on the elastic deformation displacements of the tool in relation to the workpiece, is considered. The cutting instability dependency on the skew-symmetric components o…
