Asymmetric flatness occurred on the products of a 2250mm hot rolling line when they were rolled in a cold mill. The production data reflected that these products deviated much in hot rolling. Because of the large thickness, rolled pieces show asymmetric profile instead of asymmetric flatness under asymmetric rolling c…
The application of nanomaterials, containing particles 1000 times smaller than the thickness of a human hair, is increasing but uncertainties persist regarding their potential health effects. An ongoing study to identify where nanomaterials are used in construction and to assess the impact of demolition processes on p…
Malgréle nombre important de paramètres technologiques mis en jeux, le polissage des matériaux fragiles par des grains abrasifs liés montre une grande efficacité et une qualité de surface meilleure par rapport au polissage par des grains abrasifs libres. Cette méthode permet d’obtenir des rugosités Ra et Rq de l’ordre…
In this work, we study the relation between the widths of the zero-phonon lines (ZPL) of single impurity molecules (SM) in solid matrices with local effective values of the refractive index n. Since at ultralow temperatures the width of SM ZPL is determined mainly by the radiative lifetime T1, while the local-field ef…
In the present investigation, a series of novel formazans 4[a -h]were synthesized by the condensation of Schiff bases2[a-c] and diazonium salt chloride of various substituted aromatic amines 3[a-c] .The intermediate Schiff bases (2a-2h) were itself synthesized by the condensation of different aromatic amines2( thiocar…
The potential for gamma emission tomography (GET) to detect partial defects within a spent nuclearfuel assembly is being assessed through a collaboration of Support Programs to the InternationalAtomic Energy Agency (IAEA). In the first phase of this study, two safeguards verification objectiveshave been identified. Th…
Flame retardants which contain a phosphorus moiety attached to a carbohydrate backbone were developed. To synthesize the flame retardants, carbohydrates and polyols were used as the starting materials which occur in nature and are environmentally and toxicologically safe materials. The two target structures include on…
In Slovakia, a direct disposal of spent nuclear fuel in a deep geological repository within the country after a certain period of interim storage is a preferred option. This paper briefly describes near field model of radionuclide migration developed in GoldSim simulation code environment and analyses the calculated r…
In this communication, we present some results on thermo-electric properties of various high temperature superconductors. We have performed measurements on three rare-earth based cuprate superconductors. All the superconductors were prepared using solid state reaction method. The XRD studies on the present samples ind…
Objectives In this study we investigated the potentials of dual-modal CT-MRI macrophage tracking, by a intratracheal instillation of a mixture of either gadolinium nanoparticles or barium sulphate ...
Tension-compression asymmetry in polycrystalline NiTiCu tubes was studied during elastic and transformation zone using strain gauges rosettes. Axial and transverse strain measurements from strain gauges were used to calculate a localized strain ratio through tensile and compression tests at different temperatures. The…
Nowadays, due to the new deformation processes that are being developed like the Incremental Forming Process (IFP) or the Localized-Incremental Forging Process (LIFP), indentation processes are regaining importance again. In this paper, in order to cover the largest possible number of cases in the study of indentation…
We continue here our previous work where SD powders were significantly strengthened by irradiation with electrons of lower energy under smaller dose. Previous results were obtained from the crushing strength analysis, no XRD was applied. In present work, powders of synthetic diamond with low strengthwere sorted on set…
The normal stresses of the coating sprayed on the internal surface of thick walled cylinder, subjected to uniform temperature and pressure change, are determined. The suggested approach enables one to evaluate the normal stresses in the coating and substrate, as well as the interface. The approach is applicable to jud…
A ready-to-use multifunctional coordinative system, 2,2'-dihydroxyazobenzene --aluminum (III) (DHAB--Al$^{3+})$, was created to recognize several anions effectively through three channels, namely colorimetric detection, UV-Vis spectroscopy, and fluorescence spectroscopy. Under naked eye visualization, the H$_{2}$PO$_{…
Iron oxide nanoparticles (IONPs) are used in various biomedical applications and are already applied in human therapy. Since IONPs can reach the brain, detailed knowledge on uptake and effects of IONPs on neural cells is required. In the present thesis, IONPs were synthesized and fluorescently labeled by attaching the…
Este documento presenta los resultados de una investigación sobre la influencia del Mn en solución sólida sobre la resistencia a la corrosión por picadura de dos aceros inoxidables austeníticos, uno denominado 17Cr6Mn5Ni y un acero comercial UNS S304L utilizado como material de referencia. Fueron usadas soluciones ele…
Numerous works have been done in obtaining properties involving differential subordination implications. This paper continues such efforts by considering the analytic function p and obtains differential subordination relations involving 1+βp′(z)pk(z). In particular, for k = 0, 1, 2 and 3, conditions on β are determin…
I materiali magneto-reologici e magneto-elastici rappresentano una specifica classe di materiali intelligenti che rispondono ad un campo magnetico esterno manifestando un rapido e reversibile cambiamento delle loro proprietà visco-elastiche. Le proprietà più significative di questi materiali sono l'effetto magnetostri…
Nanoscience and nanotechnology concepts are applicable across all fields of science and a more widespread application of nanomaterials and nanotechnologies is imminent or already occurring in many areas, including health care. Today's scientists take those cutting-edge technologies and concepts and apply them to medic…
