Pauleta, SR, Guerlesquin F, Goodhew CF, Devreese B, Van Beeumen J, Pereira AS, Moura I, Pettigrew GW.  2004.  Paracoccus pantotrophus pseudoazurin is an electron donor to cytochrome c peroxidase. Biochemistry. {43}:{11214-11225}., Number {35}, 1155 16TH ST, NW, WASHINGTON, DC 20036 USA: AMER CHEMICAL SOC Abstract

The gene for pseudoazurin was isolated from Paracoccus pantotrophus LMD 52.44 and expressed in a heterologous system with a yield of 54.3 mg of pure protein per liter of culture. The gene and protein were shown to be identical to those from P. pantotrophus LMD 82.5. The extinction coefficient of the protein was re-evaluated and was found to be 3.00 mM(-1) cm(-1) at 590 nm. It was confirmed that the oxidized protein is in a weak monomer/dimer equilibrium that is ionic- strength-dependent. The pseudoazurin was shown to be a highly active electron donor to cytochrome c peroxidase, and activity showed an ionic strength dependence consistent with an electrostatic interaction. The pseudoazurin has a very large dipole moment, the vector of which is positioned at the putative electron-transfer site, His81, and is conserved in this position across a wide range of blue copper proteins. Binding of the peroxidase to pseudoazurin causes perturbation of a set of NMR resonances associated with residues on the His81 face, including a ring of lysine residues. These lysines are associated with acidic residues just back from the rim, the resonances of which are also affected by binding to the peroxidase. We propose that these acidic residues moderate the electrostatic influence of the lysines and so ensure that specific charge interactions do not form across the interface with the peroxidase.

Moniz, A.  2004.  Resultados provisórios do exerc{\'ıcio Delphi WorTiS (1ª fase)[Provisional results of the 1st round of Delphi WorTiS exercise]. , Number 5936: University Library of Munich, Germany Abstract

In this working paper are present the main provisional results of the first round of a Delphi survey held in Portugal on the automotive sector. It was done under the WorTiS project, developed by IET – Research Centre on Enterprise and Work Innovation, and financed by the Portuguese Ministry of Science and Technology. The majority of experts consider to have an average of less knowledge in almost all the scenario topics presented. Nevertheless, we considered specially the topics where the experts considered themselves to have some knowledge. There were no “irrelevant” topics considered as such by the expert panel. There are also no topics that is not considered a need for co-operation (that happens in jus tone case). The lack of technological infra-structrures was not considered as an hindered factor for the accomplishement of any scenario. The experts panel considered no other international competence besides US, Japan or Germany in these topics. Although the members of the expert panel were not as many as needed, These situations will be taken into consideration for a second round of the Delphi survey

The INDICARE project – the Informed Dialogue about Consumer Acceptability of DRM Solutions in Europe – has been set up to raise awareness about consumer and user issues of Digital Rights Management (DRM) solutions. One of the main goals of the INDICARE project is to contribute to the consensus-building among multiple players with heterogeneous interests in the digital environment. To promote this process and to contribute to the creation of a common level of understanding is the aim of the present report. It provides an overview of consumer concerns and expectations regarding DRMs, and discusses the findings from a social, legal, technical and business perspective. A general overview of the existing EC initiatives shows that questions of consumer acceptability of DRM have only recently begun to draw wider attention. A review of the relevant statements, studies and reports confirms that awareness of consumer concerns is still at a low level. Five major categories of concerns have been distinguished so far: (1) fair conditions of use and access to digital content, (2) privacy, (3) interoperability, (4) transparency and (5) various aspects of consumer friendliness. From the legal point of view, many of the identified issues go beyond the scope of copyright law, i.e. the field of law where DRM was traditionally discussed. Often they are a matter of general or sector-specific consumer protection law. Furthermore, it is still unclear to what extent technology and an appropriate design of technical solutions can provide an answer to some of the concerns of consumers. One goal of the technical chapter was exactly to highlight some of these technical possibilities. Finally, it is shown that consumer acceptability of DRM is important for the economic success of different business models based on DRM. Fair and responsive DRM design can be a profitable strategy, however DRM-free alternatives do exist too.

Moniz, A.  2004.  {Elementos para o estudo de um caso de sucesso na montagem automóvel em Portugal: a Opel Portugal[Elements for the study of a success case in automobile assembly: the Opel Portugal]}. , Number 5938: University Library of Munich, Germany Abstract

The interest to study this factory of GM group in Portugal is due to the facto of being one of the oldest assembly lines of the automotive sector still operating in Portugal (it was founded in 1963). Besides that, it went recently across a very intensive technological change, and then would be interesting to know the organisation of work model chose. The Opel factory occupies at the moment the former one that belonged to Ford Lusitana. There it has being under production some modules that feed the assembly line on JIT and in sequence. Although there were severe difficulties to implement the case study at Opel, this report could be done using secondary information and several interviews at the factory and initial visits. This Opel factory was recently closed down in the frame of a GM European strategy for re-structuring.

Andersen, NH, Harnung SE, Trabjerg I, Moura I, Moura JJG, Ulstrup J.  2003.  Broad-temperature range spectroscopy of the two-centre modular redox metalloprotein Desulfovibrio desulfuricans desulfoferrodoxin, Sep 7. Dalton Transactions. :3328-3338., Number 17 AbstractWebsite

The electronic-vibrational couplings of the two-centre non-heme iron protein Desulfovibrio desulfuricans desulfoferrodoxin (DFx) in three oxidation states, i.e. fully oxidised (grey), half-oxidised (pink), and fully reduced (colourless), have been investigated by variable temperature (VT) UV/VIS, MCD, CD, and EPR spectroscopy. The UV/VIS spectra of grey DFx at room temperature is characterised by broad charge transfer (CT) transitions associated with oxidised centre 1 (495 and 368 nm) and II (335 and 635 nm). The transitions are resolved at 78 K, substantiated by VT-MCD and -CD. The data offer novel information about the electronic-vibrational couplings of the transitions. Multiphonon bandshape analysis discloses strong contributions from both local Fe-S and S-C stretching and solvent/protein modes. A number of transitions are blue- or red-shifted compared with monomeric desulforedoxin, superoxide reductase or dismutase, and cloned Desulfovibrio vulgaris DFx fragments. Conversion from grey to pink DFx is accompanied by drastic electronic-vibrational changes of both centres. The data suggest that electron transfer and optical CT-transitions of DFx are controlled by environmental reorganization in the whole region between the metal centres.

The interaction of reduced rabbit cytochrome b(5) with reduced yeast iso-1 cytochrome c has been studied through the analysis of (1)H-(15)N HSQC spectra, of (15)N longitudinal ( R(1)) and transverse ( R(2)) relaxation rates, and of the solvent exchange rates of protein backbone amides. For the first time, the adduct has been investigated also from the cytochrome c side. The analysis of the NMR data was integrated with docking calculations. The result is that cytochrome b(5) has two negative patches capable of interacting with a single positive surface area of cytochrome c. At low protein concentrations and in equimolar mixture, two different 1:1 adducts are formed. At high concentration and/or with excess cytochrome c, a 2:1 adduct is formed. All the species are in fast exchange on the scale of differences in chemical shift. By comparison with literature data, it appears that the structure of one 1:1 adduct changes with the origin or primary sequence of cytochrome b(5).

Moniz, A, Gomes C.  2003.  Impacto do desinvestimento no mercado local de emprego: o caso de uma unidade da indústria metalomecânica[Impact of divestment on the local employment market: a case of the metal industry], Sep. , Number 6862: University Library of Munich, Germany Abstract

This paper is a draft contribution for a definition of the concept of divestment. This topic is still very influenced by definitions from the fields of economics or management. Thus, from a group of definitions and approaches developed by different authors we try to elaborate on this divestment concept, searching for indicators and variables related to this practice. The founded indicators allow us to identify the main consequences and the potential social impacts due to divestment situations. Also we try to develop a methodology of research for analysis and impact framework that come from divestment action of companies.
