RESUMO: A Marca de um País também vende. A imagem de um País é nos dias de hoje um activo muito importante para a sua economia. Uma marca é uma promessa feita ao consumidor, é o ponto de referência de todas as impressões, positivas e negativas adquiridas ao longo do tempo. O Marketing é a ferramenta que deverá percepcionar, estudar e apresentar factores de diferenciação, mostrar e convencer os consumidores das qualidades de um produto ou serviço. A realidade impõe uma atenção especial ao tema e a Marca Portugal teve um boom de programas de desenvolvimento e de promoção a partir dos anos 90 do séc. XX. O responsável pela gestão da Marca Portugal é o Governo, através da AICEP, Agência para o Investimento e Comércio Externo de Portugal, que tem como missão aumentar a notoriedade de Portugal, dinamizando o investimento estruturante e a internacionalização das empresas, criando condições competitivas e estimulando a exportação no Mercado Global, diversificando a oferta dos produtos e os Países de Destino. A falta de estratégia e os planos mal sucedidos, são alguns dos erros apontados à gestão da Marca Portugal, mas é determinante assumir claramente que a assumpção da Marca e o seu Reposicionamento é um vector estratégico para o desenvolvimento do País. Portugal tem boas referências, na indústria, nos serviços, tem produto, que podem ajudar a promover a imagem global de Portugal e contribuir para o aumento das receitas, seja das exportações, do Turismo ou do Investimento Estrangeiro. Portugal precisa de um Plano de Marketing e de uma entidade gestora de Marca, que garanta uma gestão eficaz da Marca Portugal, integrada e articulada com todos os produtos e serviços estratégicos para a exportação ou para o consumo interno. Esta dissertação apresenta um Modelo de Reposicionamento da Marca Portugal que agrega todos os pontos positivos que Portugal possui, como, a sua capacidade de vendas, o seu potencial para se investir, o que há para ser visitado, e desenvolve um programa sério e transversal que promova Portugal no estrangeiro e que atraia investidores e visitantes. ABSTRACT: The Brand of a Nation also sells. The image of a country is, nowadays, an important asset for its economy. A brand is a promise made to the consumer; it is the reference point for all impressions, positive and negative acquired over time. Marketing is the tool that must perceive, study and present differentiation factors, must show and convince consumers about the qualities of a product or service. Reality demands a special attention to this topic and the Portugal Brand experienced a development and promotion program boom since the 20th Century 90’s. Currently, the figure in charge of the management of the Portugal Brand is the Government, through AICEP, whose mission is to increase the notoriety of Portugal, captivating structural investment and the internationalization of enterprises, mainly small and medium businesses, creating competitive conditions and stimulating exports to the Global Market, diversifying product offer and Destination Countries. Some errors have been pointed out in the management of the Portugal Brand, such as lack of strategy and unsuccessful plans, but it is imperative to irrevocably understand that Brand assumption and its Repositioning is a strategic vector for the development of the Country. Portugal has good references, either in industry, or services, has product, that help promoting Portugal’s global image and contributing to an increase in revenues, either in exports, Tourism or Direct Investment. Portugal needs a Marketing Plan and a Brand management entity, such as a Brand strategic executive council, to ensure an effective management of the Portugal Brand, integrated and articulated with all the products and services flagged as strategic assets for exportation or domestic use. This thesis presents a Repositioning Model of the Portugal Brand that aggregates all positive aspects that Portugal has, such as sale capacity, potential for investment, lots of places to visit, and develops a serious and transversal program to promote Portugal abroad and to attract investors and visitors alike.

Os múltiplos Vieiras que se manifestam nas cartas e sermões demonstram como um homem do Seis centos poderia se inserir nas questões temporais e espirituais. Mas, como Vieira afirmava, ele não era um homem comum, havia poucos Vieiras. A atuação multifacetada do religioso era em parte a expressão da Companhia de Jesus e de um dos seus representantes que defendia os interesses da monarquia portuguesa. A compreensão do pensamento econômico de Vieira se circunscreve dentro de faixas lineares, estabelecidas conforme a conjuntura.

Neste estudo, o autor propõe-se avaliar a problemática, centrada na realidade histórica de Portugal, das práticas devocionais em torno das relíquias de mártires e de santos.Depois de se propor uma síntese global sobre a evolução, em tempos medievais, deste universo religioso, passa-se à avaliação de um caso, o do Convento de Jesus de Setúbal, de monjas colectinas, em pleno século XVII, através da exploração de um tipo de recursos geralmente ignorado pelos historiadores: as notícias descritivas dos relicários produzidas em mosteiros e santuários nacionais dessa época. Constituindo uma expressão de devoção religiosa extremamente popular, nesses séculos, nem por isso deixam de merecer a mais profunda adesão das elites clericais e nobiliárquicas católicas.

Four races of Xanthomonas campestris pv. mal-vacearum (Xcm) viz. races 23, 27 and 32 (isolated from Gossypium hirsutum) and race 23b (from Gossypium barbadense) were studied. The plasmid profile of the natural isolates showed four plasmids in races 23 and 23b (ca. 60, 40, 23, 8.2 kb), five in race 27 (ca. 60, 40, 23, 8.2 and 3.7 kb) and six in race 32 (ca. 60, 40, 23, 8.2, 3.7 and 1.6 kb). Continuously sub-cultured laboratory isolates of the Xcm races resulted in the loss of all but two plasmids, ca. 60 and 40 kb in size. When the laboratory isolates were passed through cotton (Gossypium hirsutum), they regained certain plasmids so that four plasmids were found in race 23 and 23b (ca. 60, 40, 23 and 8.2 kb), five in race 27 (ca. 60, 40, 23, 8.2 and 3.7 kb) and six in race 32 (ca. 60, 40, 23, 8.2, 3.7 and 1.6 kb), which was more or less similar to the original isolates. The isolates recovered from cotton maintained their plasmid profile (except for minor changes in the miniplasmids) after storage for six months at -70degreesC in 50% glycerol. It is suggested that plasmid profiles among highly virulent races of Xcm are unstable during repeated sub-culturing at room temperature, resulting in rapid loss of some plasmids. However, when the cultures were sub-cultured and stored at -70degreesC the plasmid profile was fairly stable except for the miniplasmids (ca. 3.7 and 1.6 kb).

Isolates of Armillaria mellea and A. gallica that differed in virulence to healthy blackcurrant, strawberry, Lawson cypress and privet were used to inoculate plants exposed to different watering regimes. Host plants from which water had either been withheld or their roots kept constantly flooded with water, both showed increased susceptibility compared to those plants, which had been watered regularly. At the end of the period of stress, roots from randomly selected plants from each treatment were harvested. Following chemical analysis of the roots for protein, lipids, and carbohydrates including starch, in vitro assays were carried out with these substances. The increased amounts of these nutrients in both groups of stressed plants are sufficient to stimulate the growth of both A. mellea and A. gallica and enhance their virulence.

A homologous series of macrocyclic oligoamides has been prepared in high yield by reaction of isophthaloyl chloride with m-phenylenediamine under pseudo-high-dilution conditions. The products were characterized by infrared and H-1 NMR spectroscopies, matrix assisted laser desorption-ionization time-of-flight mass spectrometry, and gel permeation chromatography (GPC). A series of linear oligomers was prepared for comparison. The macrocycles ranged in size from the cyclic trimer up to at least the cyclic nonamer (90 ring atoms). The same homologous series of macrocyclic oligomers was prepared in high yield by the cyclodepolymerization of poly(m-phenylene isophthalamide) (Nomex). Cyclodepolymerization was best achieved by treating a 1% w/v solution of the polymer in dimethyl sulfoxide containing calcium chloride or lithium chloride with 3-4 mol % of sodium hydride or the sodium salt of benzanilide at 150 degreesC for 70 h. Treatment of a concentrated solution of the macrocyclic oligomers (25% w/v) with 4 mol % of sodium hydride or the sodium salt of benzanilide in a solution of lithium chloride in dimethyl sulfoxide at 170 degreesC for 6 h resulted in efficient entropically driven ring-opening polymerizations to give poly(m-phenylene isophthalamide), characterized by infrared and H-1 NMR spectroscopies and by GPC. The molecular weights obtained were comparable with those of the commercial polymer.

A family of oxorhenium (V) complexes of newly designed pyridylthioazophenolate ligands has been synthesized and isolated in pure form. The solid state structure of an organic compound (HL1) has been established by X-ray crystallography. The molecular structure observed in the solid state is that the two molecules of the ligand (HL1) in the asymmetric unit have similar geometries, except for the orientation of the pyridine ring. This series of organic moieties acts as tetradentate monobasic NSNO donor chelators in oxorhenium(V) complexes which has been characterized by elemental analyses, IR, H-1-NMR, UV-Vis. The complexes are 1: 1 electrolytes in nature in MeOH solution, the counter anion being ClO4). The electrochemical studies of the [(ReO)-O-V(L)Cl]ClO4 complexes in MeCN using TBAP as supporting electrolyte exhibit quasi-reversible voltammogram showing one-electron couple for [(ReO)-O-VI(L)Cl](2+)-[(ReO)-O-V(L)Cl](+) in the 1.11-1.29 V vs SCE range.

The possibility of preparing olive oil, with the same nutritional value and stability characteristics found in virgin olive oil, by the enrichment of refined olive oil with olive leaf polyphenols was studied. To obtain antioxidant phenols similar to those found in virgin olive oil, these components were extracted from the leaves of several olive cultivars from the Northern region of Portugal, namely, Carrasca, Ripa, Negruche, Cordovil, Verdeal, Madural, and Bical cultivars, under several conditions. The concentration of a leaf extract required for addition to refined olive oil to obtain the same stability as virgin olive oil was determined. The extract from 1 kg of leaves was sufficient to fortify 50-320 L of refined olive oil to a similar stability as a virgin olive oil sample depending on the metal concentration of the oil, cultivar, and time of the year when the leaves were picked.

In this paper we consider bilinear forms of matrix polynomials and show that these polynomials can be used to construct solutions for the problems of solving systems of linear algebraic equations, matrix inversion and finding extremal eigenvalues. An almost Optimal Monte Carlo (MAO) algorithm for computing bilinear forms of matrix polynomials is presented. Results for the computational costs of a balanced algorithm for computing the bilinear form of a matrix power is presented, i.e., an algorithm for which probability and systematic errors are of the same order, and this is compared with the computational cost for a corresponding deterministic method.

Water-soluble polymers are often capable of forming interpolymer complexes in solutions and at interfaces, which offers an excellent opportunity for surface modification. The complex formation may be driven by H-bonding between poly(carboxylic acids) and non-ionic polymers or by electrostatic attraction between oppositely-charged polyelectrolytes. In the present communication the following applications of interpolymer complexation in coating technologies will be considered: (1) Complexation between poly(acrylic acid) and non-ionic polymers via H-bonding was used to coat glass surfaces. It was realised using layer-by-layer deposition of IPC on glass surfaces with subsequent cross-linking of dry multilayers by thermal treatment. Depending on the glass surface functionality this complexation resulted in detachable and non-detachable hydrogel films; (2) Electrostatic layer-by-layer self-assembly between glycol chitosan and bovine serum albumin (BSA) was used to coat magnetic nanoparticles. It was demonstrated that the native structure of BSA remains unaffected by the self-assembling process.
