- Uma nova versão do romance A morte do Rei D. FernandoPublication . Fontes, Manuel da CostaEm 1869, Teófilo Braga publicou um extraordinário romance da ilha de S. Jorge, Açores (Cantos , nº 4; reimpresso no seu Romanceiro Geral, I: 475-77), que terminava com versos de Doliente estaba e Morir os queredes, padre, dois velhos romances épicos que ainda não tinham sido descobertos na tradição oral. O poema começa com Silvana (“í-a”; vv. 1-34)romance em que o pai, que também é frequentemente rei, pede à filha para ela se deitar com ele. A moça queixa-se à mãe, que toma o seu lugar junto ao marido, fingindo ser Silvana. .
- Fuentes paremiológicas francesas y españolas en la primera mitad del sglo XIXPublication . Sevilla Muñoz, JuliaLa literatura oral está despertando un interés cada vez mayor, lo que se refleja, por ejemplo, en el aumento de los coloquios sobre esta materia o en la creación de revistas dedicadas a estudiarla; actos muy loables, pues contribuyen a fomentar este tipo de investigación e ir cubriendo así las lagunas existentes en el estudio de las manifestaciones lingüísticas caracterizadas por su oralidad, como sucede con los refranes, los proverbios, las sentencias, las máximas.
- Estudo de polimorfismos genéticos e da sua associaçäo com capacidades de produçäo leiteira em caprinos de raça Algarvia e ovinos de raça Serra da EstrelaPublication . Barracosa, Helena Maria Guerreiro Pires; Cravador, AlfredoNeste estudo foram identificados e analisados polimorfismos de restrição (RFLPs) e conformacionais (SSCPs) a partir de DNA genómico extraído de 77 caprinos de raça Algarvia e 70 ovinos de raça Serra da Estrela. A análise por Southern fílot utilizando a enzima Pstl, revelou dois padrões RFLP designados por GH-Psíl ABC e GH-Psíl BC no gene codificante para a hormona de crescimento caprina. A análise em gel de poliacrilamida não desnaturante dos fragmentos PCR ("Polymerase Chain Reaction") desnaturados revelou a existência de polimorfismos conformacionais nos exões 9 e 10-11 do gene caprino codificaníes para a caseínas asi (3 padrões SSCP), no exão 1 da a-Lactoalbumina caprina (2 padrões SSCP) e no exão 7 do gene da P caseína caseína (3 padrões SSCP) bem como no exão 4 da k caseína ovina (2 padrões SSCP). A análise dos contrastes lineares entre o padrão RFLP designado por BC-GH-P^/I e o padrão ABC-GH-/A/I revelou que o primeiro está associado a uma maior teor proteico (p<0.08). Não foram detectadas associações sobre a quantidade de leite produzida e teor butiroso. Em relação à ccsi-caseína caprina-(exão 9) o padrão AB revelou ser superior ao padrão ABC em relação à quantidade de leite produzida (p<0.00001) teor butiroso (p<0.005) e proteico (p<0.00001) enquanto que o padrão AA (exão 10-11) da mesma caseína revelou ainda ser superior ao padrão AB em relação à quantidade de leite produzida (p<0.00001) teor butiroso (p<0.005) e proteico (p<0.00001). A quantidade de leite produzida, teor butiroso e teor proteico não parecem ser afectados pelos restantes polimorfismos conformacionais obtidos na a-La e P-caseína caprina.

- Flowering and fruit set of 'fortune' hybrid mandarin. Effect of girdling and growth regulatorsPublication . Duarte, Amílcar; Guardiola, J. L.Young orchards of 'Fortune' mandarin usually have a low productivity due to insufficient fruit set. The trees flower profusely, and most of the flowers are borne on leafless inflorescences. Leafy inflorescences are formed in a very low proportion and vegetative sprouts are nearly absent. This sprouting pattern results in a very low leaf/flower ratio. The carbohydrate reserves of the trees are lower than reported for other citrus cultivars, and are depleted shortly after anthesis. Therefore, the growth of the developing fruitlets depends mostly on current photosyntate formation. Most of the ovaries abscise shortly after flowering, having made very little growth. There is a main peak of abscission from early May until the end of June. Late fruitlet abscission lasts until late July. A GA3 spray at flowering retarded the abscission of reproductive organs, but failed to increase the final fruit set. On the other hand girdling did not affect the main wave of drop, but reduced late abscission, which resulted in an increase in set and final yield. Girdling did not increase the level of carbohydrates in the leaves, which indicates that carbohydrate use is determined by availability and fruit set may be limited by photosynthate supply.
- Seven songs from Costa RicaPublication . Cruz-Sàenz, Michèle S. deIn July of 1973, through the benificence of Professor Juan de Dios Trejos, music teacher from Cartago, Costa Rica, I had the pleasure of meeting doña Leticia de Céspedes. This tiny woman was in her nineties, with neatly cropped snow white hair and blue eyes. She received me in her humble home in Tres Ríos, a town located between San José and Cartago. Sra. de Céspedes had learned to read and transcribe music. She taught piano and guitar. She too, was interested in music which was orally transmitted, and most graciously bequeathed to me musical transcriptions which she had made from songs she had heard her grandparents sing when she was a child. She assured me that she learned them orally, and to my knowledge, they have never been recorded before now.
- A comparison of monofilament gillnet and small hook longline selectivity in a multispecies artisanal fishery in the Algarve, Southern PortugalPublication . Erzini, Karim; Santos, M. N.; Monteiro, C. C.; Gonçalves, J. M. S.; Bentes, L.; Lino, Pedro G.As part of ongoing studies concerned with the small-scale fisheries of the South of Portugal, experimental fishing was carried out with monofilament gillnets and small hook longlines within the same area. Sixty-two species were caught, of which 20 were common to both gears. Pronounced differences in terms of the relative importance of different species in the catches were observed. Size selection patterns also differed, with highly overlapped hook catch distributions and few species showing evidence for size selectivity. In contrast, strong selectivity was characteristic of species which tend to be "wedged" in gillnets. Whereas smaller stretched mesh sizes (particularly 40 and 50 mm) caught significant numbers of illegal sized fish, this was minimal in the longlines. Some implications for management are discussed.
- Ecos e ressonâncias: a onomatopéia na literatura oralPublication . Alcoforado, Doralice Fernandes XavierThis article deals with the nature of oral literature, highlighting the prosodical aspects that build the literary nature of the text. From these aspects, we chose to study onomatopoeia, one of the most expressive and explored stylistic procedures in the oral text. This study is illustrated with examples taken from folktales recently collected in the state of Bahia (Brazil).

- El amor del soldado: tradución românica, recreación culta y pervivencia moderna de una seguidilla del siglo XVIIPublication . Pedrosa, José ManuelEsta canción debió estar muy arraigada en la tradición folclórica del siglo XVII, porque también la reprodujeron, glosaron o mencionaron Andrés de Claramonte en su comedia.
- Disproportionation of ethylbenzene over SAPO-40Publication . Lourenço, J. P.; Ribeiro, M. F.; Ramôa Ribeiro, F.; Rocha, J.; Gabelica, Z.SAPO-40 exhibits strong acid sites, which catalyse the reaction of disproportionation of ethylbenzene. The distribution of diethylbenzene isomers suggests a high void volume in the structure of this molecular sieve.
- A computational study of a parallel Branch and Bound algorithm for the quadratic 0-1 programming problem on transputersPublication . Schutz, G.; Pires, F. M.; Ruano, AntonioDiscrete optimization problems are very difficult to solve, even if the dimantion is small. For most of them the problem of finding an ε-approximate solution is already NP-hard.
- Dynamic temperature models of a soiless greenhousePublication . Cunha, J. B.; Ruano, Antonio; Faria, E. A.; Couto, C.In this paper climate discrete-time dynamic models for the inside air temperature of a soilless greenhouse are identified, using data acquired during two different periods of the year. These models employ data from air temperature and relative humidity.
- Hospital, uma burocracia profissionalPublication . Monteiro, Ileana PardalNeste artigo pretende-se estudar a estrutura hospitalar à luz da configuração estrutural proposta por Henri Mintzberg para estas organizações - a burocracia profissional. Após uma breve revisão de literatura, ao longo da qual se procura destacar os principais modelos estruturais, procurou-se caracterizar a solução adoptada nos hospitais portugueses. Verificando-se que a legislação não parece contrariar os princípios da burocracia profissional, analisou-se a estrutura emergente de um hospital distrital do Sul do país, que evoluiu, em poucos anos, de uma estrutura humanista (de hospital da Misericórdia) para uma estrutura diferenciada (embora ainda com poucas valências médicas). Os resultados obtidos, a partir da análise de conteúdo de entrevistas realizadas aos membros do conselho de administração e às chefias médicas e de enfermagem do centro operacional, permitiram confirmar que se trata de uma burocracia profissional.

- Elementary, my dear Watson: the kleenex shroud in Barthelme's "Views of my father weeping"Publication . Mattos-Parreira, MerjaMy analysis of Barthelme's narrative "Views of My Father Weeping" applies loosely a Faircloughian (1992) multidimensional concept of discourse: (i) text-dimension (= the Hallidayan systemic-functional description of the formal properties of the present narrative); (ii) the analysis of text production and interpretation, that is, of discursive practice (which here consists of the reader and her socially constructed genre expectations) and thirdly, (iii) the more general, ideological context of social practice of the reading community are complemented by intertextual analysis.
- Incorporation of cobalt in the AFR structure and characterization of the resulting acid sitesPublication . Lourenço, J. P.; Ribeiro, M. F.; Ribeiro, F. R.; Rocha, J.; Gabelica, Z.; Onida, B.; Garrone, E.The AFR structure with the silicoaluminophosphate composition (SAPO-40) was known since 1984. However the synthesis of AIPO4-40 and MeAPO4-40 (Me:Co, Zn) was only reported in 1994, hence offering new potential applications of this structure.

- The activity of methaemoglobin reductase in toadfish (Halobatrachus didactylus) and gilt head sea bream (Sparus aurata)Publication . Aníbal, J.; Bicho, M.The erythrocytes intracellular oxidative stress oxidizes the haemoglobin forming methaemoglobin, which is nonfunctional. To oppose this formation fishes have an enzyme that reverses the process called methaemoglobin reductase. In vitro activity of the methaemoglobin reductase was determined in two marine fishes with different habitats and behaviours (Halobatrachus didactylus and Sparus aurata). The KM and Vmax, were determined through the Eisenthal and Cornish-Bowden Plot. The basis for this study is that the methaemoglobin reductase system has very active ferricyanide reductase activity, using NADH as the electrons donor. Halobatrachus didactylus showed higher values of methaemoglobin reductase activity (38.9 mmol NAD+/min/gHb) than Sparus aurata (27.8 mmol NAD+/min/gHb). The reductase of Halobatrachus didactylus had, for both substrates, higher values of KM (potassium ferricyanide: 0.133 mM, NADH: 0.067 mM) and lower values of Vmax (potassium ferricyanide: 0.097 min-1; NADH: 0.025 min-1), than Sparus aurata (potassium ferricyanide: KM=0.092 mM, Vmax=0.176 min-1, NADH: KM=0.032 mM, Vmax=0.062 min-1). The results indicated that Halobatrachus didactylus’s methaemoglobin reductase had high antioxidant efficiency, although that one of the Sparus aurata had more sensitivity to the presence of low concentrations of methaemoglobin. The meaning of this different behaviour, at the moment can not be envisaged.
