- Petrographic and geochemical features of Mouriscas Orthogneisses: contribution to Ossa-Morena Zone geodynamical modelPublication . Henriques, S.B.A.; Ribeiro, Maria Luísa; Moreira, Maria Eugénia Dias; Guimarães, FernandaABSTRACT: A preliminary study presents a set of variscan granitoids, which intruded the Ossa Morena Zone (OMZ), at the Arraiolos-Pavia region. Field, petrographic and geochemical characterization defines the bases for a general classification of the Ossa Morena Zone granitoids, similar to that of Central Iberian Zone (CIZ). The obtained data pointed out the occurrence of enormous volumes of basic and intermediated compositions. Granitoids containing biotite, amphibole and calcic plagioclase, granitoids are frequent, showing particular features of the OMZ, relatively to the CIZ. Geochemical data indicate sub-alkaline sequences and different magmatic sources, from mantle and crust. These sequences have reached different stages of magmatic evolution. The most evolved melts are enriched in alkalis gave compositions for the alkaline field in the TAS diagram (alkali feldspar granite). These evolved rocks have the Al2O3 values of granites.

- From need to manufacture: the design process in sustainable value approachPublication . Alexandre, Jorge; Maia, Anabela; Camocho, David; Rodrigues, Fátima; Catarino, Justina; Henriques, José João M. SilvaIn a sustainable development paradigm there must be a direct influence and a social responsible relationship between user, designer, and manufacturer. The different stakeholders interactions should be based on a dynamic influence of their needs. The challenge is to understand those needs, translate and monitor them through life cycle of products processes. The use of Value Analysis method (namely functional analysis, main phase of that methodology) and its integration with Cleaner Production, allows the development of a methodology that helps the definition of stakeholders needs and their transposition to the design, manufacturing and use phases. Due the functional approach, without techical solution in the problem definition, this kind of analysis should stimulate the criativity and the innovation. In this metodology the study subject is defined in terms of functions, quantified with technical, environmental and social criteria, in order to create a true dialogue platform between who orders and the designer, manufacturer or supplier. This approach enables to adjust either the evolution of the diffrent needs and the objectives to be attained. For the development of the work, namely the designer's one it is very important that since the beginning of the study the main objectives and constraints are defined. All this work is made by multidisciplinary team with people representing the main areas related to the study subject. The methodology allows the quantification of the functional performance (taken into account technical, social and environmental aspects) of a study subject and also all the costs related with materials, water, energy and human resources. The relationship between them will allow to quantify the Sustainable Value. In this paper we present the theoretical structure of the developed methodology and also its main results in several case studies.
- Synthesis and characterization of novel hydroxy- and aminobisphosphonatesPublication . Teixeira, Fatima; Lucas, Carla; Pereira, Inês F. A.; Curto, Maria João Marcelo; Neves, M.; Duarte, M. TeresaBisphosphonates (BPs) are a family of drugs that are successfully used in the treatment of various calcium-related disorders such as Pagetμs disease, osteoporosis and bone metastases. In addition, functional BPs have been also used in the treatment of metal intoxication and as novel ligands for well-defined radioactive metal complexes that can be used in imagiology, scintigraphy and radiotherapy applications [1,2]. The indazole derivatives are pharmacologically important compounds and the indazole ring system forms the basis of a number of drug molecules. Condensed pyrazoles are also known as pharmacophoric elements in numerous active compounds. However, in comparison with other heteroaromatic compounds, the chemistry of indazole and condensed pyrazoles remains less studied [3]. The present work is to extend the previous studies in indazolebisphosphonates [4] in order to obtain new BPs derived from indazole and condensed pyrazole with potential biological/therapeutical activities. Herein, we report the synthesis and characterization of a series of new 1-hydroxybisphosphonates (1) and aminobisphosphonates (2) (substituted at different C- or N-positions of the indazole ring - N-1, C-5, C-6, C-7)
