[ES]Se ha estudiado la variabilidad de la temperatura en la Cornisa Cantábrica en el periodo 1928-2013 analizando los índices de la temperatura máxima, mínima y media, el rango diario de temperaturas y el número de días de helada. Asimismo se ha analizado la influencia que tiene el índice NAO sobre la temperatura. Para su evaluación se han utilizado las bases de datos de catorce observatorios atmosféricos, un observatorio marítimo y el índice NAO mensual de Hurrell. Se ha observado que la temperatura de la Cornisa Cantábrica ha aumentado sobre todo en las últimas cuatro décadas, siendo mayor el incremento de la temperatura máxima que el de la mínima (1973-2013). Además, la temperatura marítima del Este del mar Cantábrico ha ascendido a un ritmo de 0,197°C dec-1. El índice NAO no muestra relación con la variabilidad de la temperatura.

O projeto de higienização, com efeitos sentidos ainda no século XIX, atravessou as primeiras décadas dos novecentos propondo intervenções cada vez mais incisivas na população brasileira, porém pautadas no princípio da educação higiênica. O pressuposto de que era necessário conscientizar e educar higienicamente a população, ao invés de impor apenas a obediência a medidas legislativas, tornou a escola primária um dos principais escopos das iniciativas em proveito da formação de hábitos sadios. Este olhar sobre a escola primária exigiu do professorado o preparo para lidar com tais desafios. Esta dissertação situa- se no âmbito da proposta de refletir acerca da interferência dos discursos e conhecimentos médico-higiênicos na formação e ofício da docência primária. Para tal efeito, tomamos como algumas das principais fontes os compêndios escolares de higiene, endereçados às escolas normais, bem como os programas da disciplina, produzidos para conduzir o ensino na Escola Normal do Distrito Federal. Tendo em vista que este aparato didático-pedagógico, composto pelos compêndios e pela disciplina de Higiene, manteve forte relação com o que se difundiu acerca do professorado primário a respeito de seu papel na campanha higiênica , também fez parte da perspectiva deste estudo o exame dos discursos proferidos nos congressos médicos e educacionais. Tais discursos nos auxiliaram no sentido de perceber a retórica que requisitava o alargamento do papel do professorado primário, no contexto das primeiras décadas do século XX, impulsionando uma suposta adequação do plano de formação docente às emergências da saúde pública. Ademais, as iniciativas voltadas para o aperfeiçoamento dos professores primários, fora das escolas normais, também se expressaram como discursos destas novas atribuições: tratamos dos cursos de aperfeiçoamento em higiene, promovidos por instituições distintas. Tornava-se necessário disciplinar a infância e suscitar nela novos hábitos. Portanto, os professores primários foram convocados a se constituírem braços direitos dos higienistas.

As narrativas em torno da busca do Graal tiveram origem no século XI e foram de grande importância para fixar a imagem de um personagem típico da sociedade medieval, o cavaleiro, como um novo modelo heroico. Nesse sentido, os cavaleiros que encontraram o Graal nessas narrativas, especialmente no ciclo literário conhecido como Matéria da Bretanha, representam a configuração máxima desse paradigma. Esta pesquisa visa analisar a permanência de tal imagem no cinema, que é igualmente uma arte narrativa, como o eram as novelas de cavalaria que originaram o modelo. O corpus a ser analisado são três significativas obras do cineasta norte-americano Terry Gilliam que direta ou indiretamente retomam a questão do Graal: Monty Python em busca do Cálice sagrado (Monty Phyton and The Holy Grail, 1974), O pescador de ilusões (The Fisher King, 1991) e Os doze macacos (Twelve Monkeys, 1995). Assim, procura-se com esta tese traçar um panorama das retomadas da imagem literária e medieval dos cavaleiros no cinema, assim como observar as mudanças no padrão dessas imagens descritas literariamente para sua representação óptico-sonora

Charles Henry Gilbert (1859-1928) was a pioneering ichthyologist who made major contributions to the study of fishes of the American West. As chairman of the Department ofZoology at Leland Stanford Junior University in Palo Alto, Calif., during 1891-1925, Gilbert was extremely devoted to his work and showed little patience with those ofa different mindset. While serving as Naturalist-in-Charge of the U.S. Fish Commission Steamer Albatross during her exploratory expedition to the Hawaiian Islands in 1902, Gilbert engaged in an acrimonious feud with the ship's captain, Chauncey Thomas, Jr. (1850-1919), U.S.N., over what Gilbert perceived to be an inadequate effort by the captain. This essay focuses on the conflict between two strong figures, each operatingf rom different world views, and each vying for authority. Despite the difficulties these two men faced, the voyage of the Albatross in 1902 must be considered a success, as reflected by the extensive biological samples collected, the many new species of animals discovered, and the resulting publication of important scientific papers.

Fishery science pioneers often faced challenges in their field work that are mostly unknown to modern biologists. Some of the travails faced by ichthyologist and, later, fishery biologist Charles Henry Gilbert (1859-1928) during his service as Naturalist-in-Charge of the North Pacific cruise ofthe U.S. Bureau of Fisheries Steamer Albatross in 1906, are described here, as are accomplishments of the cruise. The vessel left San Francisco, Calif., on 3 May 1906, just after the great San Francisco earthquake, for scientific exploration of waters of the Aleutian islands, Bering Sea, Kamchatka, Sakhalin, and Japan, returning to San Francisco in December. Because the expedition occurred just after the war between Japan and Russia of 1904-05 floating derelict mines in Japanese waters were often a menace. Major storms caused havoc in the region, and the captain of the Albatross, Lieutenant Commander LeRoy Mason Garrett (1857-1906), U.S.N., was lost at sea, apparently thrown from the vessel during a sudden storm on the return leg of the cruise. Despite such obstacles, Gilbert and the Albatross successfully completed their assigned chores. They occupied 339 dredging and 48 hydrographic stations, and discovered over 180 new species of fishes and many new species of invertebrates. The expedition's extensive biological collections spawned over 30 descriptive publications, some of which remain today as standards of knowledge.

The demersal fish stock of Wadge Bank is one of the important fish resources for both Sri Lanka and India. Sivalingam and Medcof (1957) have given an account of its history, general features and relative productivity. According to records the total fishing effort on the bank had been fluctuating and very recently the number of boats operating on the bank has suddenly increased, and there is a possibility that still more will begin operating on the bank in the near future (Mendis, 1965). The increased fishing effort with the possibility of still further increase calls for proper management practices by those concerned, in order to obtain the maximum sustained yield from the demersal stock. For this purpose a detailed study of the past performance of the fishery is essential. With this in view all records of commercial operations up to 1960 are being analysed by the present author and are to be published in a series. This is the first paper in the series and gives a detailed analysis of the first commercial trawling operations from 1928 to 1935. Since there had been a major break of about 10 years between this and the present fishery this data is being analysed separately.

An historical account is given of the development of the Lake Albert fisheries since Worthington's survey in 1928. It is noted that the development of the fisheries was related to, and dependent upon, improvements in the type of gear and canoes, an incFease in the number of canoes and outboard engines in use, improved marketing facilities and better road communications. Summarized data, collected mainly since 1954, has been analysed and tabulated to show annual exports to the Congo, total annual catches 'and annual catches of individual species. A change in the relative abundance of the various species in the annual catches is described. It is noted that this change was caused by a change-over from large to small mesh size gill-nets, and that it was associated with an increased demand within Uganda for the smaller species of fish, such as Aleste's baremose and Hydrocynus forskahlii. A brief description of fish processing and marketing in the Lake Albert region is given, which emphasizes the suitability of salt-cured fish to the social and physical environment of the area. Finally, a summary of a recent survey of the potential fish resources of the lake is given in the discussion, and estimates of the 1965 catch at the north and south ends of the lake are compared with the findings of the survey. This showed that there is little danger of overfishing the Alestes baremose stocks of the Wanseko area at the 1965 rate of exploitation of the species, and that the total catch for 1965 at the south end of the lake was well below the estimated annual sustainable yield from the area.

The yield equation given by BEVERTON and HOLT (1957) has several parameters which are difficult to estimate for tropical freshwater fish species. Nevertheless, some simplifying assumptions can be made and the most relevant parameters used to enable the construction of yield isopleths. Tilapia esculenfa has the following parameters: maximum length (L ∞=33.8 c.m. growth rate (K) = 0.32, natural mortality rate (M)=0.17 and the length at maturity (1 m)=22 cm. The optimum yield is obtained by catching the fish at a length of first capture of 26 em and a fishing mortality rate of 0.5. Tilapia nilotica with L ∞=49 cm, 1 m=36 cm, K=0.50 and M= 0.30 gives optimum yield when caught at a length of first capture of 35-36 cm with a fishing mortality rate of 0.5-0.6. The stuned Tilapia nilotica of Lake Albert has L ∞=17 cm, K=2.77,1 m=12 cm and M=3.37. With such a very high natural mortality, maximum yields would be obtained hy using a length of first capture less than 9 cm and a fishing mortality rate exceeding 1.8.

The present paper gives a full description of the organization of Acanthococcus antarcticus Hooker et Harvey, a not well known member of the Rhodophyllidaceae as well as gives for the first time description of the male and tetrasporic plants. Detailed organization of the carpogonial branches, spermatia and tetraspores is also presented. Nineteen figures illustrate the text (material collected at Deseado port, Santa Cruz prov., Argentina). The following text is the content of the discussion. From the description it is possible to confirm the position of Acanthococcus in the Rhodophyllidaceac as was done by Kylin (Kylin 1960, p. 290 et seg.). It has many similarities in the development of the carpogenic branches and in the formation of spermatia as well in the production of the zonately divided tetrasporangia with the genera of the family whose reproduction is known; Cystoclonium purpureum (Hudson) Batters and Rhodopyllis bifada (Good. et Woodw.) Kützing (Kylin 1923); Calliblepharis jubata (Good. et Woodw.) Kützing (Kylín 1928) and Craspedocarpus erosus (Hook. et Harvey) Sehmitz (Kylin 1932). Apparently the distinguishing feature of Acanthococcus is the structure of the vegetative frond, with the abundant development of rhizoidal filaments in the medula, besides the characteristic appendages of the cystocarps. Harvey's figure (Harvey 1847, P. 181, Fig. 3) of the tranverse section of the plant shows the central portion composed of a dense small-celled medula limited by a region of large cells which is externally covered by a small-celled cortex. As we have seen the small-celled filaments are not restricted to the central portion, but extend into the large-celled portion and can reach the cortex. On the other hand, the eros section of Acanthococcus depicted by Kützing (Kützing 1867, T. 93, Fig. h, under Callophyllis antartica), apparently belongs to another plant, so different in the structure when one compares his figure with Harvey's and the ones in this paper. RESUMEN EN ESPAÑOL Este trabajo presenta una completa descripción de la organización de Acanthococcus antarcticus Hooker et Harvey, un miembro poco conocido de las Rodofilidáceas, así como presenta por primera vez descripciones de las plantas masculinas y de las tetraspóricas. También por primera vez es presentada la organización detallada de las ramas carpogoniales, de los espermecios y de las trásporas. Diecinueve figuras completan el texto (material coleccionado en Puerto Deseado, Prov. Santa Cruz, Argentina).
