La integración de la perspectiva de género en la programación de los fondos de la UE en el perÃodo 2007-2013
Número temático: Lógicas de desenvolvimento social inclusivo e sustentávelNeste artigo tenta-se explorar as estratégias de integração do mainstreaming de género e das ações especÃficas de apoio à igualdade de mulheres e homens nos programas operacionais (PO) do Fundo Social Europeu (FSE) e do Fundo Europeu de Desenvolvimento Regional (FEDER). Perspetiva-se a integração das questões de género na programação, dando-se a conhecer a forma como a igualdade de género foi pensada em sede de planeamento do Quadro de Referência Estratégico Nacional e em sede de regulamentação da execução do FSE e do FEDER. Os resultados apresentados derivam das análises produzidas sobre os documentos estratégicos disponÃveis de cada PO.This paper tries to explore the strategies of integration of gender mainstreaming and specific actions to support equality of women and men in the operational programs (OPs) of the European Social Fund (ESF) and European Regional Development Fund (ERDF). Perspective the integration of gender issues in programming, giving themselves known how gender equality was designed based on the Planning Strategic Reference Framework and seat regulations implementing the ESF and ERDF. The results presented are derived from analyzes produced on the strategic documents available for each PO
Synthesis of non-proteinogenic amino acids from N-(4-toluenesulfonyl)dehydroamino acid derivatives
By treating N-(4-toluenesulfonyl)-N-(tert-butyloxycarbonyl)-dehydroamino acid derivatives with different reactants under different conditions, a variety of new amino acids are obtained, viz. (i) alpha-alcoxy-alpha-amino acids, (ii) alpha,alpha-diamino acids and (iii) novel beta-substituted dehydroamino acids. (C) 2002 Elsevier Science Ltd. All rights reserved.Fundação para a Ciência e a

Electrochemical synthesis of diaminodicarboxylic acid derivatives
Diaminoadipic acid derivatives were synthesized in good yields by electrolysis of N,N-diacyidehydroalanines. Cyclic voltammetry measurements on the precursors are presented and interpreted as supporting formation of a nucleophilic intermediate generated by electrochemical reduction.

Synthesis of 2,3,5-substituted pyrrole derivatives
2,3,5-Substituted pyrrole derivatives are prepared by treatment of 2,3-dihydrofuran derivatives with trifluoroacetic acid. These in turn are obtained by Michael addition of carbon nucleophiles of the beta-dicarbonyl type to N-(4-toluenesulfonyl)-N-(tert-butyloxycarbonyl)-dehydroalanine methyl ester.- Fundação para a Ciência e a Tecnologia(POCTI/1999/QUI/32689
Cyclic voltammetry studies on substituted arenesulfonhydrazides
Additional Z and Boc groups on the vicinal nitrogen of sulfonyl hydrazines have no significant effect on the cathodic potential of the sulfonyl functions as measured by cyclic voltammetry, whereas a Boc group on the geminal nitrogen invariably gives rise to shifts of about 0.2 V to less negative potential similar to those previously observed for derivatives of amines.This work was supported by the Swedish Natural Science

Supporting effective unexpected exception handling in workflow management systems within organizaional contexts
Tese de doutoramento em Informática (Engenharia Informática), apresentada à Universidade de Lisboa através da Faculdade de Ciências, 2008Workflow Management Systems (WfMS) support the execution of organizational processes within organizations. Processes are modelled using high level languages specifying the sequence of tasks the organization has to perform. However, organizational processes do not have always a smooth flow conforming to any possible designed model and exceptions to the rule happen often. Organizations require flexibility to react to situations not predicted in the model. The required flexibility should be complemented with robustness to guarantee system reliability even in extreme situations. In our work, we have introduced the concept of WfMS resilience that comprises these two facets: robustness and flexibility. The main objective of our work is to increase resilience in WfMSs. From the events demanding for WfMS resilience, we focused on ad hoc effective unexpected exceptions as those for which no previous knowledge exist is the organization to derive the handling procedure and no plan can be a priori established. These exceptions usually require human intervention and problem solving activities, since the concrete situation may not be entirely understood before humans start reacting to the event. After discussing existing approaches to increase WfMS resilience, we have identified five levels of conformity. The fifth level, being the most demanding one, requires unrestricted humanistic interventions to workflow execution. In this thesis, we propose a system to support unrestricted users' interventions to the WfMS and we characterize the interventions as unstructured activities. The system has two modes of operation: it usually works under model control and changes to unstructured activities support when an exception is detected. The exception handling activities are carried out until the system is placed back into a coherent mode, where work may proceed undermodel execution control
Efficient synthesis of dehydroamino acid derivatives
By using a DMAP catalysed reaction of P-hydroxyamino acid derivatives with tert-butylpyrocarbonate, the corresponding dehydroamino acid derivatives were obtained in high yields.- (undefined
Michael addition of thiols, carbon nucleophiles and amines to dehydroamino acid and dehydropeptide derivatives
Michael additions of nitrogen heterocycles, thiols, carbon nucleophiles and amines to dehydroalanine derivatives, including a glycyldehydroalanine peptide, were performed in fair to good yields. Dehydroaminobutyric acid derivatives reacted only with the stronger nucleophiles but in considerably lower yields and often no reaction was observed with the corresponding dehydrophenylalanine derivatives. When a tosyl group was bonded to the nitrogen atom of the dehydroamino acid, in some cases the addition product underwent elimination of this group and yielded the corresponding b-substituted derivative of the a,b-dehydroamino acid. Addition of some b- dicarbonyl compounds led to formation of products to which the structure of a,a-disubstituted cyclic amino acid derivatives was assigned
High yielding synthesis of dehydroamino acid and dehydropeptide derivatives
By using a dimethylaminopyridine (DMAP) catalysed reaction of b-hydroxyamino acid derivatives with tert-butylpyrocarbonate [(Boc)2O], dehydroamino acid derivatives are obtained in high yields. The same methodology applied to dipeptides with a b-hydroxyamino acid residue gives the corresponding dipeptides with a dehydroamino acid residue
