The innovation is directed to an expandable stent for implantation in a body lumen, such as an artery.A stent is a small hollow metallic wire mesh which is placed in choked coronary arteries to help keep them distended to ensure sufficient flow of blood. A stent, the key element of such a treatment – called angioplast…
For low-rise buildings frame technologies have got significantly widespread. One of the directions is using lightweight steel thin-wall constructions (LSTC).To promote this technology in Ukraine it’s necessary to develop guidelines that reflect the structural features of this constructions type based on existing codes…
Nanotechnology, which is the one of the most rapidly emerging fields of the present day, has shown many promising applications in the field of electronics, communication, environmental remediation, medicine, agriculture and health care among others. However, as is seen with any technological advancement and innovation…
A commercial two-components epoxy resin formulation was modified by adding graphene and related materials (GRMs). GRMs were used as additives in different concentration in order to improve thermomechanical properties of the final nano-composite thermoset. Different dispersion methods were taken into account in order t…
Ciprofloxacin(1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-7-(1-piperazinyl)-3-quinoline carboxylic acid),is a member of synthetic antibacterial agent widely used in clinical practice for the treatment of various gram negative and positive microorganisms.In concurrent use of Ciprofloxacin with cations, they may bind toget…
Researches and publications about luminescent polymers have been developed in the last years due the academic innovation 1 ; however the application is very limited at industrial area. Optical markers processed are few explored due the difficult to process this kind of luminescent materials. The materials used to obta…
Trond is now Senior Corporate Advisor to the Nemko Group management, stationed at Nemko’s head office in Oslo, Norway. Until official retirement last year, he was Senior Vice President of the company with responsibility for international cooperation. He has more than 30 years of experience with conformity assessment a…

The octahedral CuI microcrystals were synthesized in mixed solvent of water and ethanol at 180 °C for 20 h under solvothermal condition. The compared experiments were also carried out under various condition, and the optimum process was fixed. The results show that the suitable ripening process is helpful for growth o…
Herein we report on the sensor activity of three blue-emitting triazine derivatives of 2-aminoterephthalic acid. The novel compounds are configured as a “fluorophore-receptor” system. The fluorophores designed can act as a pH-probe via an “off-on-off” fluorescence sensing mechanism due to an internal charge transfer.…
Background: Polyaniline (PAni) has been one of the most promising materials for numerous practical applications because of its well-defined yet controllable redox states and doping level. However, the processability of pure PAni materials that is, either pure emeraldine salt or base is crucial since its properties are…
Shear waves possess large information in the study of the technical condition of engineering materials. In the case of occurrence of stress or plastic deformation along a certain direction, the velocity of shear waves polarized along and across of this direction will vary in different ways. A value characterizing this…
Introduction: Carbon Steel pipes are used as feeder pipes in Pressurized Heavy Water Nuclear Reactors for carrying the coolant from the inlet headers to the coolant channel and again from outlet of the coolant channel to the outlet headers and are part of the Primary Heat Transport (PHT) System of Reactor. It has been…
Computational Methods: A 3D model, using COMSOL Multiphysics® v4.3 RF Module, was constructed to enable parametric studies. The simulations were performed in two steps: (1) compute the electric field for the substrate only when illuminated by a plane-wave excitation at the upper boundary; (2) solve for the electric fi…
Pharmaceutical packaging is one market across the globe which is advancing at constant pace. It is expected that market will grow to worth $78.79 Billion by 2018 [1]. Packaging is a key for sale, safety and success. Like other packaged goods, pharmaceuticals packaging need to be in such a manner that it will provide s…
Voltage sags and swells in the medium and low voltage distribution grid are considered to be the most frequent type of power quality problems based on recent power quality studies. Their impact on sensitive loads is severe. In this paper, the performance of voltage-source converter-based series compensators used for l…

This research aims to propose a method for testing the shear strength of wood parallel to fiber and compare with other proposed methods. The method proposed by NBR 7190/1997 Brazilian Standard, that is similar to ASTM D 143-09/2010, the uses a rectangular prismatic specimen with an indentation to prevent its rotation,…
The structure, physical and mechanical properties of samples produced from pure and titanium alloyed copper powder using equal-channel angular pressing with complex deformation route have been investigated. The samples were manufactured using the technology of pressing, sintering and deformation by equal-channel angul…
In a constant progress of a regulatory and environmental context, the diagnostic and the expertise of the corrosion, the determination of its causes and factors, and the proposed solutions to this phenomenon represent a real challenge for all stakeholders of industry. We propose in this paper to a complete study of th…
