Critical analysis of the main changes and expected impacts of transposition of directive 2013/34/UE for Portugal
This study aimed to develop a critical analysis of the changes introduced by Directive 2013/34/U.E. starting from the identification of the main differences and recommended it until now and anticipate the expected impacts of these changes at the level the preparation and dissemination of financial information in Portugal. It was intended to identify the main implications of the transposition of the Directive in the accounting profession and the surrounding (company), particularly with regard to the administrative costs incurred by companies with the preparation of the financial information and on a social level. To answer to the main objectives of the study it was applied a questionnaire to profession in Vila Real and Bragança districts. The results show that the transposition of the new Directive implies greater responsibility for the profession, neglect concepts from international standards and focuses on reducing the burdens on businesses in detriment of the information quality.info:eu-repo/semantics/publishedVersio
A Diretiva 2013/34/U.E.: principais alterações e previsÃveis impactos da sua transposição
O presente estudo teve como objetivo geral desenvolver uma análise crÃtica das alterações introduzidas pela Diretiva 2013/34/U.E. a partir da identificação das principais diferenças nela preconizadas e as até agora prescritas e antecipar os expectáveis impactos dessas alterações ao nÃvel da preparação e divulgação da informação financeira em Portugal. Pretende assim, identificar as principais implicações da transposição da referida Diretiva na profissão de Técnico Oficial de Contas (TOC) e na envolvente (empresa), nomeadamente no que respeita aos custos administrativos a suportar pelas empresas com a preparação da informação financeira e no plano social. Para dar resposta aos principais objetivos do estudo aplicou-se um inquérito por questionário a TOC nos distritos de Vila Real e Bragança. Concluiu-se que a transposição da nova Diretiva implica maior responsabilidade para o TOC, que descuida conceitos oriundos das normas internacionais e que privilegia a redução dos encargos das empresas em detrimento da qualidade da informação.info:eu-repo/semantics/publishedVersio
Electrical Characterization Of Epitaxial Layers Of In0.71ga 0.29as0.63p0.37
We have performed measurements of carrier concentration and Hall mobility, between 4.2 K and room temperature, in InGaAsP (energy gap of 0.96 eV) epitaxial layers grown on semi-insulating InP. It is shown that for this kind of material in the range of concentration studied (2.0×101 6-1.6×1018 cm-3), alloy scattering has to be taken into account as a mechanism limiting the mobility even at low temperatures. Also, in the entire range of temperature and concentration studied, Fermi-Dirac statistics are better suited than Boltzmann statistics for theoretical calculations of Fermi energy, because even for concentrations as low as 2.0×1016 cm -3, the material is degenerated at low temperatures. Following these assumptions, we have calculated the alloy scattering potential as being between 0.52 and 0.62 eV.641235238IEEE AESS,IEEE Instrumentation and Measurement Societ
2-Styrylchromones as novel inhibitors of xanthine oxidase. A structure-activity study
The purpose of this study was the evaluation of the
xanthine oxidase (XO) inhibition produced by some
synthetic 2-styrylchromones. Ten polyhydroxylated
derivatives with several substitution patterns were
synthesised, and these and a positive control, allopurinol,
were tested for their effects on XO activity by
measuring the formation of uric acid from xanthine. The
synthesised 2-styrylchromones inhibited xanthine oxidase
in a concentration-dependent and non-competitive
manner. Some IC50 values found were as low as 0.55mM,
which, by comparison with the IC50 found for allopurinol
(5.43 mM), indicates promising new inhibitors.
Those 2-styrylchromones found to be potent XO
inhibitors should be further evaluated as potential
agents for the treatment of pathologies related to the
enzyme’s activity, as is the case of gout, ischaemia/
reperfusion damage, hypertension, hepatitis and cancer
Determinants Of Blood Lead Levels In An Adult Population From A Mining Area In Brazil
During the last fifty years the Ribeira river valley, Brazil, had been under the influence of the full activity of a huge lead refinery and mining along the riverside. The plant completely stopped all kind of industrial activities at the end of 1995, and part of the worker population and their families still remain living nearby in small communities. The objective of the present study was to assess the determinants of blood lead levels (BLL) in these mining areas, where residual environmental contamination from the past industrial activity still remains. Blood samples of 350 adults aged 15 to 70, residing in areas around the mine and the refinery were collected. A questionnaire was given in order to gather information on food habits, current and former residential places, occupational activities, among other variables. Blood lead concentrations were analysed by graphite furnace atomic absorption spectrometry using Zeeman background correction. Logistic regression analysis was conducted to examine the independent contribution of selected variables in predicting BLL in those subjects. The following variables showed significant association with high BLL: residential area close to the lead refinery, former dwelling at the refinery village, male gender, smoking habits, and consume of fruits from home back yard.107I127130Berglund, M., Pedersen, N.L., Bjorkman, L., Vahter, M., (1999) Environ Res, 80, pp. 222-230Brody, D.J., Pirkle, J.L., Kramer, R.A., Flegal, K.M., Matte, T.D., Gunter, E.W., Paschal, D.C., (1994) JAMA, 27, pp. 277-283Hense, H.W., Filipiak, B., Novak, L., Stoeppler, M., (1992) Int J Epidem, 21Jakubowski, M., Trzcinka-Ochocka, M., Razniewska, G., Christensen, J.M., Starek, A., (1996) Int Arch Occup Environ Health, 68, pp. 193-198Kristal-Boneh, E., Froom, P., Yerushalmi, N., Ashkanazi, R., Pardo, A., Shine, R., Ribak, J., (1998) Am J Ind Med, 34, pp. 512-516Leroyer, A., Hemon, D., Nisse, C., Bazerques, J., Salomez, J.L., Haguenoer, (2001) Sci Total Environ, 267, pp. 87-99Liou, S.H., Wu, T.N., Chiang, H.C., Yang, G.Y., Yang, T., Wu, Y.Q., Lai, J.S., Chang, P.Y., (1996) Sci Total Environ, 180, pp. 211-219Mahaffey, K.R., (1995) Environ Health Perspect, 103, pp. 191-196Muldoon, S.B., Cauley, J.A., Kuller, L.H., Scott, S., Rohay, J., (1994) Am J Epidemiol, 139, pp. 599-608Ooi, P.L., Goh, K.T., Heng, B.H., Sam, C.T., Kong, K.H., Rajan, U., (1991) Rev Environ Health, 9, pp. 2017-2213Paoliello, M.M.B., Gutierrez, P.R., Turini, C.A., Matsuo, T., Mezzaroba, L., Barbosa, D.S., Alvarenga, A.L.P., Lobo, B., (2001) Pan Am J Public Health, 9, pp. 315-319Probst-Hensch, N., Braun-Fahrlaender, C., Bodenmann, A., Ackermann-Liebrich, U., (1993) Soz Praventivmed, 38, pp. 43-50Yang, J.S., Kang, S.K., Park, I.J., Rhee, K.Y., Moon, Y.H., Sohn, D.H., (1996) Int Arch Occup Environ Health, 68, pp. 199-20

The liquid-vapor interface of an ionic fluid
We investigate the liquid-vapor interface of the restricted primitive model
(RPM) for an ionic fluid using a density-functional approximation based on
correlation functions of the homogeneous fluid as obtained from the
mean-spherical approximation (MSA). In the limit of a homogeneous fluid our
approach yields the well-known MSA (energy) equation of state. The ionic
interfacial density profiles, which for the RPM are identical for both species,
have a shape similar to those of simple atomic fluids in that the decay towards
the bulk values is more rapid on the vapor side than on the liquid side. This
is the opposite asymmetry of the decay to that found in earlier calculations
for the RPM based on a square-gradient theory. The width of the interface is,
for a wide range of temperatures, approximately four times the second moment
correlation length of the liquid phase. We discuss the magnitude and
temperature dependence of the surface tension, and argue that for temperatures
near the triple point the ratio of the dimensionless surface tension and
critical temperature is much smaller for the RPM than for simple atomic fluids.Comment: 6 postscript figures, submitted to Phys. Rev.
A New Relativistic High Temperature Bose-Einstein Condensation
We discuss the properties of an ideal relativistic gas of events possessing
Bose-Einstein statistics. We find that the mass spectrum of such a system is
bounded by where is the usual chemical
potential, is an intrinsic dimensional scale parameter for the motion of an
event in space-time, and is an additional mass potential of the
ensemble. For the system including both particles and antiparticles, with
nonzero chemical potential the mass spectrum is shown to be bounded by
and a special type of high-temperature
Bose-Einstein condensation can occur. We study this Bose-Einstein condensation,
and show that it corresponds to a phase transition from the sector of
continuous relativistic mass distributions to a sector in which the boson mass
distribution becomes sharp at a definite mass This phenomenon
provides a mechanism for the mass distribution of the particles to be sharp at
some definite value.Comment: Latex, 22 page
