O presente trabalho foi desenvolvido em um lixão desativado do município de Lages-SC durante o ano de 2014. Foram quantificadas as concentrações dos elementos radioativos (Urânio, Tório e Potássio). O lixão desativado do município de Lages-SC localizado entre as coordenadas 27º46´15,38’’S e 50º15´10,92’’O em uma área…
Resumen-Se evalu la resistencia a la corrosin de recubrimientos obtenidos por pulverizacin de un blanco de cromo sobre sustratos de acero AISI H13, mediante el anlisis de espectroscopia de impedancia electroqumica (EIS) y curvas de polarizacin Tafel en una solucin de NaCl al 3% en peso. Se encontr que estos recubrimie…
Amplitude-phase phenomena observed in the interaction and self-action of acoustic waves in polycrystalline solids characterized by dissipative and reactive dislocation-caused nonlinearity are studied in the framework of the modified linear part of the Granato-Lücke dislocation theory of absorption.
We construct a mesoscale model of colloidal suspensions that contain solutes reversibly adsorbing onto the colloidal particle surfaces. The present model describes the coupled dynamics of the colloidal particles, the host fluid, and the solutes through the Newton-Euler equations of motion, the hydrodynamic equations,…
Several nuclear plants were built worldwide and will need to be shut down in a specific time for being near their recommended lifespan which is about 40 years. For this reason, the aims of the International Atomic Energy Agency (IAEA) is to guide and recommend guidelines for the implementation of decommissioning activ…
To reduce the storage time of spent fuel its radiotoxicity must be reduced through the transmutation of minor actinides. Generation IV reactors or sub-critical Accelerator Driven Systems (ADS) are options that appear technically feasible in view of the transmutation goal. The purpose of this work is to design a lead-c…
Two phenomenological models of hysteretic equations of state for media with imperfect elasticity are described and compared. On the basis of these equations, a theoretical study of nonlinear phenomena caused by the acoustic wave propagation is performed. The profiles, parameters, and spectra of waves are determined. T…
A Consultants’ Meeting on “Recommended Input Parameters for Fission Cross-Section Calculations” was held at IAEA Headquarters, Vienna, Austria to define the scope, deliverables and appropriate work programme of a possible Coordinated Research Project (CRP) on the subject. Presentations are available online at https://…
Two new crystals MgCl2·2H2O·2C2H4(OH)2 (1) and MgCl2·6H2O·C2H4(OH)2 (2) assembled by MgCl2·6H2O and C2H4(OH)2 have been synthesized. Structures of 1 and 2 have been determined by single-crystal X-ray diffraction analyses and elemental analyses, IR, Raman spectra, powder X-ray diffraction and TGA. The complex 1 is tric…
This Chapter deals with the description and results of experimental studies of nonlinear low-frequency and high-frequency phenomena in rod resonators made of: glass with artificial cracks, polycrystalline rocks (coarse and fine grained sandstone, limestone, marble and magnesite), and metals (zinc and copper subjected…
known density in the samples, the measurements were density-calibrated and the increase in density and accompanying reduction in porosity due to reprecipitation of corrosion products were quantified. Our results demonstrate the potential of X-ray tomography in non-destructive quantification of corrosion processes in p…
The Savannah River Site (SRS) is a Department of Energy (DOE) complex covering roughly 800 km2 of southwest South Carolina. Traditionally, hazards posed by SRS operations
The combustion chemistry of even simple fuels can be extremely complex, involving hundreds or thousands of kinetically significant species. The most reasonable way to deal with this complexity is to use a computer not only to numerically solve the kinetic model, but also to construct the kinetic model in the first pla…
Deterioration of bridge decks is a primary factor limiting the lifespan of bridges especially in cold climates where deicing salts are commonly used. While controlling deck cracking or decreasing the permeability and porosity of concrete can improve performance and service life, chloride and moisture ingress as well a…

We report a $^7$Li nuclear magnetic resonance (NMR) study of a frustrated three-dimensional \mbox{spin-$\frac12$} antiferromagnet Li$_{2}$CuW$_{2}$O$_{8}$ and also explore the effect of non-magnetic dilution. The magnetic long-range ordering in the parent compound at $T_{\rm N}\simeq$ 3.9~K was detected from the drast…

Heterogeneity within tumour cell populations is associated with an increase in malignancy and appears to play an important role during cancer metastasis. Using in silico experiments, we study the interplay between collective behaviours and cell motility heterogeneities in a model system. Working with tumour spheroids…
