Nonetheless, this “new medium”, and, in particular, its Web 2.0 version has become the cornerstone of communication strategies for both political parties and their candidates. Seve...

The pyrimidinones mhcpe, 2-methyl-3H-5-hydroxy-6-carboxy-4-pyrimidinone ethyl ester (mhcpe, 1), 2,3- dimethyl-5-benzyloxy-6-carboxy-4-pyrimidinone ethyl ester (dbcpe, 2) and N-methyl-2,3-dimethyl-5- hydroxy-6-carboxyamido-4-pyrimidinone (N-MeHOPY, 3), are synthesized and their structures determined by single crystal X-ray diffraction. The acid–base properties of 1 are studied by potentiometric and spectrophotom...

Organisational and strategic communication research: european perspectives

The diversity represented in this book, not only in respect to author nationality, but also in theoretical and empirical approaches, reflects one of the most salient features of the European Communication Research and Education Association: Organisational and Strategic Communication Section’s identity. The spectrum of themes analysed in this collection – crisis communication, government communication, organisat...

Binding of oxovanadium(IV) complexes to blood serum albumins

In this work the binding of VIVO2+ and VIVO-complexes to serum albumins {human serum albumin (HSA), bovine serum albumin (BSA) and porcine serum albumin (PSA)} are studied using circular dichroism (CD), electron paramagnetic resonance (EPR) and visible absorption spectroscopy. The results confirm previous findings that VIVO2+ occupies at least two types of binding sites on albumin: ‘the strong vanadium binding ...

A identidade e a imagem das relações públicas em Portugal

Public Relations industry in Portugal has been expanding in recent years.

Retórica e Mediatização: As indústrias da persuasão

Vanadium (IV and V) Complexes of Reduced Schiff Bases Derived from the Reaction...

The reduced Schiff bases of salicylaldehyde [and o-vanillin (o-van)] with D,L- and L-diaminopropionic acid (DPA), designated by salDPA, and L-2,4-diaminopentanoic acid [ornithine (Orn)], designated by salOrn, as well as the VIVO2+ and VVO2+ complexes of salDPA were prepared. The compounds were characterised in the solid state and in solution. The structure of H4salDPA+Cl- was determined by X-ray diffraction. Co...
