The structure，electrical and magnetic properties of the half doping phase separated Eu0.5Sr0.5MnO3 manganite have been systematically studied. The results show that Eu0.5Sr0.5MnO3 compound has the O′ orthorhombic structure and shows typical Jahn-Teller distortion. It is found that ferromagnetic phase turn up near 75 K…
In the Gas Fast Reactor development plan, ALLEGRO is the first necessary step towards the electricity generating prototype GFR. The ALLEGRO start of operation is planned by 2020. This needs to define all design options in 2010 and to start detailed design studies in 2013. ALLEGRO is a low power Gas Cooled Fast Reactor…
On November 1st 2008, a new ordinance came into force in Sweden. It extends the implementation of nuclear liability to all nuclear facilities and companies, regardless of size. The Government has authorized the Swedish Radiation Safety Authority (SSM) to issue further regulation as warranted and appropriate, and commi…
The study of high pressure structural stability and equation of state of f-electron based binary intermetallics of type AXBY, where A belongs to either rare earth of actinide atom and B any other d or p block metal, is interesting from both basic as well as applied research point of view. These studies have lead to so…
Este trabalho descreve as sínteses de hidrogéis superabsorventes a base de acetato de celulose (AC), com grau de substituição 2.5, reticulado com dianidrido 3, 3', 4, 4' benzofenona tetracarboxílico (BTDA). As caracterizações das matérias primas foram realizadas por análises térmicas (TG/DTG) e espectroscopia na regiã…
and thin-film phosphors were deposited on conventional and corrugated substrates to test their applicability for use in transparent plasma display panels (PDPs). The exact target structure and stoichiometry of and transferred well to the single-phase film by optimizing the deposition conditions. The corrugated substra…
Metallurgical phenomena taking place during processing of TRIP Steel are investigated and described with the aim of achieving better understanding of the microstructure development throughout the entire integrated processing routes. Different TRIP steel structure sizes were created by controlling the hot rolling proce…
The photocatalytic degradation of crystal violet on copper oxide semiconductor suspended in aqueous solution has been carried out. The progress of reaction has been studied spectrophotometrically by observing absorbance of reaction mixture at different time intervals. The effects of various parameters such as concentr…
Evaporation of moisture, usually sweat, is essential for the maintenance of heat balance under most conditions when personal protective clothing is worn. Evaporation provides cooling where otherwise body heat losses would not be able to match metabolic heat generation (7). The energy equivalent of evaporating water or…
The kinetics of glucose electrooxidation on different catalysts has been studied at physiological conditions (pH 7 and 37 °C). Electrochemically activated rough gold, rough gold modified with a self-assembled monolayer (SAM) of cystamine and an enzymatic electrode based on a charge transfer complex (CTC) and glucose o…
With the development of bulk metallic glasses (BMG) in recent years, more and more scientists in solid state physics are trying to understand the mechanism of glass-formation in terms of thermodynamics and kinetics, while engineers in metallurgy are trying different compositions and processes to improve the mechanical…
Population genetic structure of seven natural populations of Toona ciliata var.pubescens was studied with simple sequence repeat(SSR) markers.The results showed that a low level genetic diversity was detected in the populations of T.ciliata var.pubescens.Average number of alleles and effective number of alleles(Ne) we…
There is a growing interest, inspired by advances in technology, in the low temperature physics of thin films. These quasi‐2D systems show a wide range of ordering effects including formation of striped states, reorientation transitions, bubble formation in strong magnetic fields, etc. The origins of these phenomena a…
A fast method to obtain the molar composition of garnets starting from their Raman spectra was recently proposed. The method, called MIRAGEM—MIcro‐RAman Garnets Evaluation Method is based on the assumption that in a garnet solid‐solution the Raman wavenumbers are linear combinations of end‐member wavenumbers, weighted…

In the article, original relations enabling the estimation of the variance of a random signal mean square value digital estimator are derived. Three cases are considered: first when the estimator is determined from quantized samples; second, when it is additionally assumed that the conditions of Widrow's theorem are s…
Rail fastenings are one of basic elements of the top structure of a track. Elastic pads are the important element of the rail fastenings. Definition of their elastic characteristics is necessary for the subsequent studying of the dynamic interaction between the track and the rolling stock.
Metamaterials (MTMs) are broadly defined as artificial composite materials specifically engineered to produce desired unusual electromagnetic properties not readily available in nature. The most interesting unusual property achievable with MTMs is probably negative refraction, which is achieved when both the permittiv…
