Humanização. Uma Reflexão na Perspectiva dos Cuidados Paliativos

Este artigo pretende reflectir sobre a temática humanização dos cuidados na perspectiva dos cuidados paliativos. É dada uma panorâmica geral do que é a humanização, através da exploração do seu conceito e do parecer de alguns autores que desenvolveram trabalhos neste âmbito. O significado da humanização depende do contexto com o qual se correlaciona. A humanização dos cuidados paliativos deve ter como base a su...

Aspectos Éticos do Final de Vida em Cuidados Paliativos

Vanadium(IV and V) Complexes of Schiff Bases and Reduced Schiff Bases Derived f...

Several sal2en-type reduced Schiff bases have been prepared from the reaction of 2 equiv. of salicylaldehyde (or derivatives) with ethylenediamine followed by reduction with NaBH4 and subsequently characterised. The water-soluble ligands (SO3-sal)2en and R(SO3-sal)2en (SO3-sal = salicylaldehyde-5-sulphonate) have been studied by pH potentiometry and 1H NMR spectroscopy and the protonation constants of R(SO3-sal...

A supramolecular zigzag chain of organometallic dipoles mediated by PF6 2- anions

Complex Fe( 5-cyclopentadienyl)(PMe3)[P(OPh)3](4–NCC6H4NO2) [PF6] has been characterized by spectroscopic and X-ray diffraction in order to evaluate the tuning of the electron density at the metal center and the extension ofthe delocalization on the molecule due to the presence of phosphite and phosphine co-ligands. The compound crystallizes in the centrosymmetric space group P21/c which destroys the possibil...

N,N'-Ethylenebis(pyridoxylideneiminato) and N,N'-Ethylenebis(pyridoxylaminato):...

The Schiff base N,Nprime-ethylenebis(pyridoxylideneiminato) (H2pyr2en, 1) was synthesized by reaction of pyridoxal with ethylenediamine; reduction of H2pyr2en with NaBH4 yielded the reduced Schiff base N,Nprime-ethylenebis(pyridoxylaminato) (H2Rpyr2en, 2); their crystal structures were determined by X-ray diffraction. The totally protonated forms of 1 and 2 correspond to H6L4+, and all protonation constants wer...

Fractional discrete-time signal processing: scale conversion and linear prediction

Nonlinear Dynamics, Vol. 29 ; A generalisation of the linear prediction for fractional steps is reviewed, widening well-known concepts and results. This prediction is used to derive a causal interpolation algorithm. A reconstruction algorithm for the situation where averages are observed is also presented. Scale conversion of discrete-time signals is studied taking as base the fractional discrete-time system t...

Synthesis of new donor/acceptor 5-cyclopentadienyl and 5-indenyliron(II) comp...

New complexes of the type [Fe( 5-Cp or Ind)(L)(L )(p-NCR)][BF4] (L, L =CO, P(OC6H5)3, P(C6H5)3; R=C6H4N(CH3)2, C6H4NO2, (E)-C(H) C(H)C6H4NO2, (E)-C(H) C(H)C6H4N(CH3)2) have been synthesised and characterised. Spectroscopic data were analysed in order to evaluate the tuning of the electronic density at the metal centre and the extension of the -delocalisation on the molecule, due to the presence of coligands w...

Fractional signal processing: scale conversion

In Proceedings of the “ECCTD '01 - European Conference on Circuit Theory and Design, Espoo, Finland, August 2001 ; Scale conversion of discrete-time signals are studied taking as base the fractional discrete-time system theory. Some simulation results to illustrate the behaviour of the algorithms will be presented. A new algorithm for performing the zoom transform is also described.

Electrochemical and structural studies of nickel (II) Schiff base complexes der...

The oxidative chemistry of three Ni(II) complexes with Schiff base ligands derived from salicylaldehyde and diamines with different steric demands, N,N9-2-methylpropane-2,3-diyl-bis(salicylideneiminate)nickel(II) (1), N,N9-1,2-cyclohexyl-1,2-dyil-bis(salicylideneiminate)- nickel(II) (2) and N,N9-2,3-dimethylbutane-2,3-diyl-bis(salicylideneiminate)nickel(II) (3), was studied by cyclic voltammetry and chronoamper...

A new family of organometallic Ni II benzonitrile derivatives bearing strong donor substituents of general formula Ni - C H P C H NCC H R PF R NH , N CH , C H , OCH , H, F has been synthesized. A structural study by X-ray 5 5 6 5 3 6 4 6 2 3 2 6 5 3 diffraction of the compound with R NH showed crystallization on the centrosymmetric monoclinic space group, P2 n, with a quasi 2 1 planar structure of the coordinat...
