This paper presents an accurate and efficient approach to optimize radiation transport simulations in a stochastic medium of high heterogeneity, like the Very High Temperature Gas-cooled Reactor (VHTR) configurations packed with TRISO fuel particles. Based on a fast nearest neighbor search algorithm, a modified fast R…
lavanones present a unique structural feature known as chirality, which distinguishes them from all other classes of flavonoids. Thus, rapid, selective and sensitive analytical methods are in need for the enantioseparation of flavanones in order to determine the genuine bioactive source. The most applicable chiral sta…
In the present investigation, an attempt has been made to prepare sustained release microspheres of Glibenclamide by using Eudragit RS 100 as rate retardant polymer. Microspheres were successfully prepared by nonaqueous emulsion solvent evaporation method. Magnesium stearate was used as hydrophobic dispersant and drop…
Lipid - based delivery systems are becoming increasingly popular as carriers of drugs due to their ability to overcome barriers to or al absorption. The objective of the present study was to prepare novel lipid - based formulation of a sparingl y soluble drug, Raloxifene hydrochloride (RLX) to increase its saturation…
We present ARABESQUE, a new tool for protein structure analysis, which includes structure comparison, generation of annotated structural alignments, and annotated superposition of structures. By combining differential geometry and knot theory, this method produces an accurate analysis of structural conservation in a f…
This paper presents an overview of the nanoparticle-cross-adaptation-sensitization (NPCAS) model for homeo- pathic remedy actions in living systems. The model builds upon an extensive interdisciplinary scientific literature outside conventional biomedicine. The way in which homeopathic remedies are made, involving tri…
Adipose tissue is a source for regenerative medicine applications contains mesenchymal stem cells (MSCs). One of the unique features of MSCs is their trans-differentiation property. Identification of MSCs is accepted by their CD105, CD90 and CD73 markers expression. In lipo aspirate from buttocks and abdominal adipose…

In this study, the silica aerogel which was used to prepare nanocomposite was synthesized on the basis of Tetramethylorthosilicate (TMOS) and co-precursor of Methyltrimethoxysilane (MTMS), in standard solgel synthesis which was followed by drying of gels at ambient pressure In the present research, silica aerogel-acti…
The effects of sulphuric acid modification on the structural and bleaching performance of Ukpor clay were investigated. The clay samples from Ukpor were mined; washed; sun-dried; sized to 0.075mm particle size and reacted with different concentrations of sulphuric acid ranging from 1M to 6M. The raw and acid modified…
Within the framework of hexagonal lanthanum oxide ( h - La 2 O 3) formation, lanthanum hexaboride film on sapphire substrate ( LaB 6/ Al 2 O 3) was oxidized at different temperatures (700-1000 °C) under reduced atmospheric pressure (1·10-2,1.5·10-1Torr) during 30 min. The composition evolution of La 2 O 3/ LaB 6 struc…
A dynamic model of the PEMFC system is developed to investigate the behaviour and transient response of the fuel cell system for automotive applications. The system accounts for the fuel cell stack with coolant, humidifier, heat exchangers and pumps. Governing equations for fuel cell and humidifier are implemented int…
This work investigates the possibility of preparing new eco-sustainable hemp based composite materials by means of an agro-industrial production chain set up. The physical, mechanical and microstructural properties of the hemp composite materials were investigated. Moreover, thermal insulating conductivity measurement…
A flexible and versatile solution to voltage quality problems is offered by active power filters. Currently they are based on PWM converters and used to connect to low and medium voltage distribution system in shunt or in series. Active power filters can perform one or more of the functions required to compensate powe…
Introduction Isotropic super finishing (ISF) is a technology that public literature suggests having potential for increased power density (Ref. 3). Three tests were conducted to test the surface durability difference between honing and ISF. Demonstration of bending fatigue strength was out of scope. Previous testing h…
Ferroelectric, piezoelectric thin film material and processes are gaining more and more importance for innovative devices that are focusing on miniaturization, high performance and integration. A piezoelectric thin film MEMs platform has been developed that enables miniaturized ultrasound transducers that operate in t…
A series of isocyanide complexes, [Fe(Porphyrinoid)((t)BuNC)(2)](+), were synthesized and examined for their physicochemical properties. The molecular structure of the bis((t)BuNC) adduct of the iron(III) porphycene (1) and corrphycene (2) adopting the (d(xy))(2)(d(xz), d(yz))(3) ground state were determined for the f…
The group of low energy electron microscopy at ISI AS CR in Brno has developed a methodology for very low energy scanning electron microscopy at high image resolution by means of an immersion electrostatic lens (the cathode lens) inserted between the illumination column of a conventional scanning electron microscope a…
The Computational Nuclear Physics group at Lawrence Livermore National Laboratory (LLNL) is developing a new tool, named ‘Kiwi’, that is intended as an interface between the covariance data increasingly available in major nuclear reaction libraries (including ENDF and ENDL) and large-scale Uncertainty Quantification (…
We report in this paper a dual catalytic effect of water soluble soft coordination supramolecular polymers (SCSPs) based on Fe3+ and a bis-ligand. Upon assembling the Fe(III)-SCSPs onto electrodes via layer-by-layer technique, the electroactive films may lower the half-wave potential for all the tested molecules and e…
