Ultraviolet laser operating at 355 nm has been found to have wide applications in scientific and industrial fields of laser radar, biological fluorescence medicine, micro processing, laser marking and laser ablation, owing to its superior properties of short wavelength, high single-photon energy, and high resolution.…
In nowadays, reducing emissions of the nitrogen oxide (NOx) in diesel engines become a principal goal for the future. The new technology Lean NOx Trap (LNT, is also known like NOx adsorber catalyst (NAC) or NOx Storage and Reduction (NSR) catalyst) can be applied on passenger cars, light and heavy-duty diesel engines…
Graphene has been a superstar in the fields ranging from materials science to condensed-matter physics since 2004. Graphene possesses good thermal and mechanical properties, high electron transfer capability and relatively low production cost. As a consequence, graphene has been used in the areas of multi-functional a…
As a key point to applying and studying magnetic photonic crystal technology, communication devices such as the magnetic photonic crystal filters with high performance and easy integration are developed. We investigate the feasibility of ferrite magnetism materials that can be used to make photonic crystal filters. Th…
The use of plasma polymerised films to fabricate highly functional surface coatings is a well-established process. Plasma polymerisation offers many advantages over conventional polymerisation techniques such as fast processing speeds, industrial scalability and the elimination of catalysts and solvents. The large bre…
Modern approaches to the management structure of the weld metal produced by arc, laser and electron beam welding. Analyzed various methods of modifying metal, including application of a mechanical treatment prior to welding, the introduction into the melt of various modifying additives, the implementation of an extern…
Two rare species of diatom algae, Chamaepinnularia circumborealis and Neidiopsis wulffii, are recorded in water courses and waterbodies in the Yamal Peninsula (Western Siberia, 69°16′2.8″–70°33′53.6″ N, 68°04′10.3″–68°9′57.46″ E). New data on their ecology and distribution are provided. A SEM study of these species ha…
Abstract Crystals of K3Ln(PO4)2 (Ln: Lu, Yb, Er, Ho, Dy, Gd, Nd, Ce, Y, Sc) and M3Lu(PO4)2 (M: Rb, Cs) are prepared from a M4P2O7/Ln2O3 flux (Pt crucible, 1235 °C, 4 h) and their crystal structures are determined by single crystal XRD and powder neutron diffraction.
We report the first mid-infrared flat lens based on the reflectarrays with focusing efficiency (70%), which is the highest reported so far for reflectarray-based lenses. Experiments and simulations show that the focusing is near diffraction-limited.

The near fields in the proximity of a small ferrite particle with magnetic-dipolar-mode (MDM) oscillations have space and time symmetry breakings. Such MDM originated fields, called magnetoelectric (ME) fields, carry both spin and orbital angular momentums. By virtue of unique topology, ME fields are strongly differen…
Abstract. We present the first analysis of population structure and cohort distribution in a fossil oyster shell bed based on 1121 shells of the giant oyster Crassostrea gryphoides (von Schlotheim, 1813). Data derive from terrestrial laser scanning of a Lower Miocene shell bed covering 459 m2. Within two transects, in…
Abstract: Detailed studies of the resolution of a EUDET-type beam telescope are carried outusing the DATURA beam telescope as an example. The EUDET-type beam telescopes make useof CMOS MIMOSA26 pixel detectors for particle tracking allowing for precise characterisation ofparticle-sensing devices. A profound understand…
Evaluation of the possibility of substitution of steel part in the car body by the one made of AZ31 alloy was the objective of the paper. Bracket in the support of the steering wheel was selected for the analysis. Two criteria were selected to evaluate the possibility of using the Mg alloy part: i) stiffness of this p…
Introduction: Postpartum pain is the pain caused by uterus intermittent contractions after placenta leaves the uterus that sometimes needs narcotics to relieve it. Due to the harmful effects of the drugs, tend to use herbal medicines has been increased. This study was performed with aim to compare the effects of dill…
In this paper the processes that take place in the dumps and methods of formation of the landfill gas were first theoretically analysed, and then on the specific cases. The proper management of the landfill gas is examined. The potential treatment of the landfill gas is shown through the scheme, and it provides an ove…
A force-dense and very efficient direct drive transverse flux generator aimed for wave power applications is being developed at the Royal Institute of Technology in Sweden. The machine is specialized for low speeds, and the design of a linear version is presented in this paper. The basic electromagnetic design is give…
Cadmium oxide thin films are important materials for applications in various photoelectric, solar cell, optoelectronic and other kinds on devices. There are several physical or chemical synthetic methods have been used to prepare transparent CdO films as described by many researchers. The X-ray diffraction study has c…
The theoretical and experimental analysis of modification of the Kolsky method for tests of materials in elastostrained ferrule is carried out. The formula for definition of radial strain of the specimen by the impulse of strain registered on an external surface of a ferrule is obtained. This formula is based on solvi…
Cement based materials such as concrete and mortar are widely used in construction industry. One of the drawbacks of concrete or mortar is its low tensile strength that will affect cracking. Thus, enhancing its tensile strength using short fibres is beneficial in reducing problems caused by cracks. This study highligh…
