The safety analysis of a Nuclear Power Plant (NPP) is based on the application of complex computer codes that are able to simulate the physical behaviour of the system under normal operations and abnormal conditions. Therefore, such codes must be extensively and continuously verified and validated in order to demonstr…
Th e challenge for cardiovascular tissue engineers is to design hemocompatible biomaterials that promote neo-tissue formation. Cardiovascular implants are prone to occlusion caused by surface thrombogenicity. In native tissue non-thrombogenic surface is provided by the endothelium. Endothelialization of implantable ca…
Unsubstituted copper phthalocyanine (CuPc) thin films were prepared using spin coating technique. The effects of post-deposition annealing of CuPc films on the NO2 gas sensing properties were studied. The results showed that the films annealed at 150 °C have highest sensitivity, highest response rate and lower respons…
Streszczenie — Poliuretany syntezowane w dwuetapowym procesie poliaddycji diizocyjanianu trimetyloheksametylenu (TMDI), poli(-kaprolaktono)diolu o ro?nym cie?arze cz¹steczkowym (PCL 750, PCL 1250) i glicerolu (GLI), poddano biodegradacji w symulowanych warunkach kompostowania z wykorzystaniem wermikulitu jako inertneg…
Much effort has been made to minimize the number and consequences of fuel failures at nuclear power plants. The consequences of control rod failures have also gained an increased attention. In this paper we introduce a system for on-line surveillance of control rod integrity which has several advantages comparing to t…
The structure of a stiff thin film on a compliant substrate has important applications in stretchable electronics. However, such structures are micro-nano-order of magnitude, where surface effects cannot be ignored. Gurtin-Murdoch theory is applied to model the thin film including surface effects. Through energy metho…
The deactivation mechanism of Pt/γ-alumina and Pd/γ-alumina catalysts for gas sensor by hexamethyldisiloxane (HMDSO) exposure has been investigated. The chemical state and local structure of Pd in the catalysts has been characterized under the reduction and oxidation after HMDSO exposure by in situ X-ray absorption fi…
Ethical and regulatory aspects are important in practice of medicine, and the same applies to nanomedicine. As has happened with introduction of all new technologies, in healthcare, these issues need to be considered. The FDA is formulating specific regulations relevant to nanobiotechnology products. The development o…
In this work TlBiTe 2 were grown by a modified Bridgman technique and examined samples had different lateral dimensions of twins, ranging from 0.1 µm to 1 µm.The average lateral size of the twins seems to affect free carrier concentration and plasma frequency.Infrared spectra were analyzed by two models, the extended…
The title complex, bis(O-propyldithiocarbonato-κ2S,S′)(2,2′-bipyridine-κ2N,N′)nickel(II) [Ni(S2COCH2CH2CH3)2(C10H8N2)], was synthesized by the reaction of bis(O-propyldithiocarbonato)nickel(II) with the bidentate ligand 2,2′-bipyridine in acetone. It crystallized in the tetragonal space group I42d with the following u…
Hysteresis motors are super high speed motors that used in special industries such as high-speed centrifuges, micro gas turbines, and etc. They are basically synchronous motors; however they can works in asynchronous mode. In most reported applications it is controlled in open-loop scheme and there isn’t any considera…
The influence of the addition of sulfuric acid to the frequently-used HF-HNO3-H2O etching mixtures has been studied. Nitrogen-oxygen cations, which are supposed to be crucial in the silicon oxidation process, are stabilized by sulfuric acid. Raman spectroscopy is suitable for determination of intermediates and for the…
Surface water is characterized by changeability of composition/content and organic intensity of both natural and anthropogenic impurities. As a result of chemical changes developed in the process of oxidation and disinfection, impurities and organic admixtures may become harbingers of damaging by-products of these pro…

Nowadays, the application of cellulose as renewable polymer and bio materials has been a great attraction for most researchers to optimize the production of cellulose through the fermentation of Acetobacter Xylinum sp. The latest technology of the optimization process which known as Response Surface Methodology (RSM)…
The present paper describes safety goals and principles for Generation IV energy systems, with emphasis on prevention and mitigation against severe accidents in the safety design corresponding to Level 4 of the defense-in-depth architecture. Consistent with them, a deterministic safety design approach has been applied…
