Brazil has great protein residue availability, specially collagen due to large meat production such as bovine, pork and poultry. The aim of this work is the study of the influence of the addition of collagen (extracted from breast chicken skin) in chicken pate. Collagenous material presented in dry basis: 55.03g/100g…
The corrosion of mild steel in aerated solutions containing different chloride concentrations (0.0585, 0.3, 3.5, 5.85, and 10% NaCl) has been investigated using different electrochemical techniques such as linear polarisation resistance (LPR), potentiodynamic polarisation (PDP), and electrochemical impedance spectrosc…
e values of the time constant spectra. This method was tested over several contaminated sites. In this extended abstract we show a new interpretation result measured over a refuse dump in Hungary near Felsőtelekes. The analysis of the IP data shows that there are some very high contaminated parts in waste-rock bodies.…
An X-ray photon-quantum-noise-limited voltage-controlled oscillator (VCO)-based pixel architecture in amorphous-silicon (a-Si) technology is reported for large-area digital medical imaging applications. In this research, the X-ray generated input charge on the input capacitor is converted into an oscillating frequency…
AgOs(2)O(6) prepared from ion-exchanged superconducting β-pyrochlore KOs(2)O(6) has been shown to be non-superconducting. Synchrotron x-ray structure refinement suggests that AgOs(2)O(6) has the Ag ion mostly occupying the low-symmetry 32e site in the [Formula: see text] space group of proper occupancy, which is diffe…
Based on the optical activity of liquid crystal, a new approach for the stealth of “cat’s eye” targets is proposed in this paper. It imitates the physiological close reaction of human eyes when strong light irradiates eyes. With this approach, the “cat’s eye” effect will vanish, which is applied in restricting photo-e…
On the physical modeling results the possibility of determination of pipelines natural frequencies and mode shapes using acoustic noise records is demonstrated. It is shown that this information can be used for diagnosing instability of above-ground pipeline supports. Partial and especially total support instability e…
Military operations performed by UN and NATO forces within the framework of stabilization missions revealed the weak points of the equipment utilized by these organizations.It turned out that one of the most dangerous threats is posed by partisan missiles equipped with cumulative heads.These missiles are mostly based…
In the last decades passive gamma-ray spectrometry became more interesting as proxy for mapping of soil parameters. For usage of gamma-ray data in Digital Soil Mapping a translation by geophysical transfer-functions into soil parameters is needed. A prerequisite to develop such functions is a reliable comparison betwe…
We take a wide-angle view of the problem of monolayer graphene (MLG) where spin-degeneracy lifting is assumed to be possible by wedging in the tunable Rashba spin-orbit coupling(RSOC) and the sub-lattice staggered potential. We next consider the AB-stacked bi-layer graphene (BLG) system (the A-carbon of the upper shee…
Background and Aims: The present study has designed to explore synthesis method of poly(methyl vinyl ether–alt-maleic acid)(MVEM)/Pluronic F127(F127) copolymer for drug delivery. Pluronic F127 has been studied extensively as drug delivery vehicle due to its excellent biocompatibility and pronounced micellization behav…
The structural and electronic properties of BN x As 1-x alloys have been investigated in the total range of nitrogen by the FP-LAPW method based on DFT within the EV-PW-GGA scheme. The equilibrium lattice constants, bulk moduli, first-order pressure derivatives of the bulk moduli, and cohesive energies have been obtai…
Recent progress in approaches to determine the elastic constants of solids starting from the microscopic particle interactions is reviewed. On the theoretical side, density functional theory approaches are discussed and compared to more classical ones using the actual pair potentials. On the experimental side, video m…
Many researchers have studied aggregation of microgel particles; however, the majority of these studies have been limited to single-component system in which homoaggregation is observed. On the other hand, less attention has been given to multi-component systems whereby heteroaggregation is seen. As such, heteroaggreg…
Il presente rapporto espone una metodologia per il calcolo degli inventari di combustibile per i reattori LWR al variare del burnup. Vengono presentati i principali fenomeni fisici connessi al bruciamento ed al decadimento in nocciolo del combustibile nucleare, i parametri fisici da cui dipende la composizione isotopi…
In questo rapporto viene studiato un assembly per PWR 17x17 privo di barre di controllo ricorrendo al codice deterministico APOLL02 versione 2.8-3.E, il cui utilizzo è reso possibile grazie ad un accordo STC siglato tra ENEA e CEA nel 2011. Viene dapprima studiata una singola pin, al variare della discretizzazione rad…
In questo rapporto viene presentato in dettaglio il nocciolo di un PWR da 900 MWe della classe francese CP1, con particolare riferimento alla configurazione del primo ciclo, o ciclo di avviamento. Per tale configurazione viene descritta la metodologia di calcolo per librerie di sezioni d'urto equivalenti a 2 gruppi e…
\n Embora o Brasil ocupe a primeira posição no ranking mundial de produção de lima ácida Tahiti, somente 6,6% desta produção é exportada. Tal aspecto deve-se, parcialmente, às perdas provocadas por danos pós-colheita, as quais estão distribuídas ao longo da cadeia de comercialização da fruta, desde a colheita até o co…
Due to electric explosion of a copper conductor in a dielectric the research carried out allowed obtaining a composite with a regulated structuring at φ≥0,06vI%Cu and with directed changes in electrophysical properties.
