El miedo al judío en la España de la Edad Media

Resumen: En este trabajo se estudia la fi gura del judío como posible inspirador de miedo para la sociedad hispanocristiana medieval, lo que parece estar en íntima relación con la imagen que de él se conformó a lo largo de la Edad Media en los derechos civil y canónico. Al analizar las distintas causas de temor inducidas por los judíos, se distingue entre los factores que causaban miedo físico, que muy probablemente tenían un componente más popular e irracional, aun cuando con frecuencia pudieran ser temores inducidos desde medios intelectuales, y los factores generadores de miedo espiritual, de naturaleza más intelectual y racional.

El proceso contra Jato Tello (Vitoria 1485): ¿Error judicial o empleo de la justicia penal en la política antijudía?

[ES]El objeto de este artículo es saber hasta qué punto pudo emplearse la justicia penal como un instrumento más de la política de carácter antijudío desarrollada por las autoridades cristianas de la España medieval a finales del siglo XV, concretamente en los momentos previos a la expulsión. Para indagar sobre esta cuestión se tendrá presente el proceso penal por blasfemia al que fue sometido el judío de Vitoria (Álava) Jato Tello.

Israel: una sociedad en tensión constante

[ES]Israel es un país marcado por la excepcionalidad. Con esto quiero referirme a que su forma de nacer, el contexto regional donde está ubicado y su propio desarrollo, han hecho de este país un verdadero laboratorio social. El estado hebreo se ha constituido desde el concepto de judeidad y mediante la inmigración judía masiva, lo que ha hecho que en su seno se den numerosas opciones identitarias. Todo ello casi en constantes guerras con sus vecinos árabes y sufriendo el zarpazo del terrorismo. Esto ha hecho que en Israel aspectos como la seguridad, el ejército y los Derechos Humanos hayan sido variables que este país ha tenido y tiene que gestionar. Esta realidad ha determinado de manera decisiva su articulación como sociedad y su propio desarrollo político tanto nacional como internacional. Este artículo pretende dar algunas claves para entender la complejidad de una sociedad, la israelí, en tensión constante.

Studies in vortex motion

This thesis covers four different problems in the understanding of vortex sheets, and these are presented in four chapters.

In Chapter 1, free streamline theory is used to determine the steady solutions of an array of identical, hollow or stagnant core vortices in an inviscid, incompressible fluid. Assuming the array is symmetric to rotation through π radians about an axis through any vortex centre, there are two solutions or no solutions depending on whether A^(1/2)/L is less than or greater than 0.38 where A is the area of the vortex and L is the separation distance. Stability analysis shows that the more deformed shape is unstable to infinitesimal symmetric disturbances which leave the centres of the vortices undisplaced.

Chapter 2 is concerned with the roll-up of vortex sheets in homogeneous fluid. The flow over conventional and ring wings is used to test the method of Fink and Soh (1974). Despite modifications which improve the accuracy of the method, unphysical results occur. A possible explanation for this is that small scales are important and an alternate method based on "Cloud-in-Cell" techniques is introduced. The results show small scale growth and amalgamation into larger structures.

The motion of a buoyant pair of line vortices of opposite circulation is considered in Chapter 3. The density difference between the fluid carried by the vortices and the fluid outside is considered small, so that the Boussinesq approximation may be used. A macroscopic model is developed which shows the formation of a detrainment filament and this is included as a modification to the model. The results agree well with the numerical solution as developed by Hill (1975b) and show that after an initial slowdown, the vortices begin to accelerate downwards.

Chapter 4 reproduces completely a paper that has already been published (Baker, Barker, Bofah and Saffman (1974)) on the effect of "vortex wandering" on the measurement of velocity profiles of the trailing vortices behind a wing.

Autobiografia de ficção como matéria de historicidade em João do Rio e em João Gilberto Noll

A análise de arquivos jornalísticos para a formação do conceito de historicidade em torno das obras Memórias de um rato de hotel (1912), de João do Rio, e Bandoleiros (1985), de João Gilberto Noll, foi a nossa primeira contribuição para a formação do objeto autobiografia de ficção, ou autoficção, como também denominamos. A partir desses arquivos de memórias, relativos a dois contextos finisseculares, o XIX e o XX respectivamente, pudemos compreender a historicidade como matriz do nosso objeto autoficção, permeada pelo que Foucault chama de efetividade cotidiana. Essa efetividade do cotidiano é costurada pelo fio da oralidade, que se refere ao elenco das atividades humanas no todo social, tendo como principal característica a ação comunicativa entre os sujeitos. Assim, ligamos a oralidade à historicidade em duas perspectivas complementares: os ditos e os escritos. A primeira diz respeito aos processos da comunicação humana e suas trocas simbólicas, que são projetadas na cultura: os ditos. A segunda se refere ao produto das representações literais do sujeito, grafadas no dorso impresso da memória: os escritos. A memória é a chave de acesso à escrita do si, que se distingue do que chamamos de autoficção, porque nessa última prevalecem as experiências do tempo presente para o futuro. Memórias de um rato de hotel é a escrita de um Eu-autor, contando do cárcere as suas experiências de gatuno no contexto da belle époque carioca. Por meio da memória, ele reconstrói o contexto finissecular, enfatizando a degradação urbana e a decadência ética da burguesia em ascensão, nos tempos da recém-inaugurada República. Na autoficção Bandoleiros, temos o relato vertiginoso de um Eu-narrador, contando do seus fracassos literários e conjugais. Ele é um escritor decadente, transitando nos espaços degradados da pós-modernidade, retirando dessa perambulação o material vivo de seu livro Sol macabro. Nessa autoficção, Noll registra as impressões sobre a realidade dos 1980, focalizando as subjetividades agônicas à margem do capitalismo tardio, num trânsito indômito entre Porto Alegre, Rio de Janeiro e os Estados Unidos. Na nossa tese, compreendemos a realidade como a matéria plástica da autobiografia de ficção. A experiência mundana do escritor é também forte aliada na composição de uma estética subjetiva, ou subjestética, que está para além do auto-retrato narcísico da autobiografia, em suas formas tradicionais

Movendo-se pelas estradas: a formação errante de Jack Kerouac

A proposta deste trabalho é analisar o romance On the Road, do escritor Beat Jack Kerouac em diálogo com a tradição da Literatura de Viagem. O estudo baseia-se em duas perspectivas em especial: a escrita de si e a escrita do outro. No que diz respeito a esta última, observamos os tons etnográficos e historiográficos que aparecem no romance e remetem à tradição. No que tange a escrita de si, observamos como a obra se comporta em relação ao caráter de Romance de Formação muito comum em relatos de viagem. Por conclusão, sugerimos que a obra por vezes dá continuidade, por vezes rompe com essas vertentes. On the Road e seu autor estariam, portanto, sempre em movimento

Entremeio: a constituição de um espaço bureaucrático individual

A presente dissertação acompanha os desdobramentos e estudos realizados durante a elaboração do trabalho intitulado Entremeio: a constituição de um espaço bureaucrático individual. Nela foram destacadas três momentos temporais e textuais: o movimento de chegada a uma cidade estranha e a elaboração do conceito de artista forasteiro, bem como o momento de adaptação ao novo e as perambulações por uma cidade a se desvelar e pulsar em uma potência transbordante; o desenvolvimento de uma coleção de perguntas capturadas em meio aos escritos de diversos autores, observando o efeito de apropriação das mesmas para a constituição de um trabalho artístico que leva em conta a distribuição silenciosa e unilateral de perguntas pelo tecido social da cidade; por fim, a criação de um trabalho que transporta o espaço individual de estudos e trabalho (bureau) para o meio de circulação pública, através da livre ocupação de espaços públicos, abordando as implicações espaciais do público e do privado. Este ensaio busca, ainda, explorar o formato ensaístico de escrita levando em consideração o relato de experiência no decorrer da elaboração de um trabalho artístico

Ensiled product from fish by microbial fermentation

Fish ensilage for animal feed stuff was prepared from Jew fish (Pseudosciaena spp.) and Silver bellies (Leiognathus spp.) by fermentation with pure culture of Lactobacillus piantarum NCIB 6105. The precooked ensiled product gave better product of fish silage (high content of lactic acid, about 5%). Protein Nitrogen content ranged between 1.76 to 1.94%. During storage for one year, the Protein Nitrogen loss was not significant. The material can be used as a supplemental animal ration.

Early developmental stages of Nandus nandus (Ham.)

In order to study the early developmental stages of Nandus nandus an experiment was conducted, where eggs and milt were obtained from the laboratory reared N nandus by stripping after 15 hours of 150 mg/kg body weight of carp PG extract injection. Then the eggs were fertilized in the laboratory and subsequent developmental stages were studied. First cleavage (two cell), four cell, eight cell, sixteen cell and multi cell stages were found 30, 50, 70, 105 and 160 minutes after fertilization respectively. Morula, early gastrula, middle gastrula, late gastrula and yolk plug stages were found 5, 8, 9, 11 and 13 hours after fertilization respectively. Hatching occurred within 20±2 hours after fertilization, and larvae were measured 1.60 mm in diameter. After one hour of hatching two melanophore bands were found at the caudal region of the body of the larvae. Eyes were first observed in l 0 hours, pectoral and pelvic fin buds appeared in 22 hours and well developed in 38 hours old larvae. Mouth cleft and brain lobes were visible when the larvae were 34 and 38 hours old respectively. Myomeres partially appeared in 16 hours, which were clearly visible in 74 hours old larvae. Larvae started wandering and searching for food after 56 hours of hatching. The yolk sac was completely absorbed when larvae became 62 hours old.

Quality assessment of rotating and solar tunnel dried marine fish product

Studies were conducted to evaluate the quality aspects of marine dried fish i.e. silver jew fish (Johnius argentatus), Bombay duck (Harpodon nehereus) and ribbon fish (Trichiums haumela) products produced in rotating and solar tunnel dryers. On the basis of organoleptic characteristics such as colour, odour, texture, broken pieces, insect infestation and overall quality, four member panels of experts evaluated the quality of the dried products obtained from both rotating and solar tunnel dryers and all the products were found in acceptable quality. Reconstitutions properties of samples were in the range of 51.05 to 98.75% for the dried fish produced in rotating dryer, while 24.64 to 76.76% for dried fish produced in solar tunnel dryer. The highest reconstitution rate was found in dried silver jew fish and lowest in ribbon fish produced in rotating dryer. On the other hand, the highest reconstitution was observed in dried silver jew fish and lowest in dried Bombay duck produced in solar tunnel dryer. Proximate composition such as moisture, crude protein, lipid and ash content of the dried fish muscles produced in rotating dryer ranged from 16.36% to 19.1%, 62.35% to 67.37%, 6.37% to 10.75% and 7.00% to 8.05%, respectively and in solar tunnel dried fish products, they were in the range of 14.05% to 19.71%,57.64% to 69. 21%,6.92% to 15.40%and 7.69% to 8.80 %, respectively. The TVBN values of dried fish products obtained from rotating dryer were in the range of 15.02 to 19.05 mg/100g, while in solar tunnel dried fish products, the values were in the range of 15.46 to 19.21 mg/100g. The results of the studies indicated that dried fish produced from both rotating and solar tunnel drier were acceptable quality in terms of organoleptic and food quality aspects.

Nutritional quality of some food fish

The proximate compositions and amino acid make-up of silver jew fish (Johnius argentatus), Indian halibut (Psettodes erumei), grey mullet (Mugil cephalus) and pearl spot (Etroplus suratensis) are reported. Calorific values of these fishes have been calculated from their proximate compositions and their amino acid make-up compared with the available data for beef and egg. From the study, pearl spot is adjudged to be the most nutritive among the fishes studied, followed by Indian halibut, grey mullet and silver jew fish.

Distribution of phosphorylase in some fish and shell fish

Phosphorylase content in the muscle of some fish and shell fish were estimated. Jew fish (Johnius dussumeri) and 'sea naran'(Penaeus indicus) recorded the highest enzyme content among the fish and shell fish studied. As phosphorylase is the key enzyme in glycogenolysis, which is the energy source of fish for muscular activity, the possible role of phosphorylase content as an index of muscular capacity and post-mortem autolysis is discussed.

Preparation and storage of cutlet from low-priced fish

Cutlets have been prepared from the minces of lizard fish (Saurida tumbil), threadfin bream (Nemipterus japonicus), jew fish (Johnius dussumieri) and miscellaneous fish. The storage characteristics of cutlet (both raw and flash fried) at 4°C, -8°C and -20°C were studied. Cutlets prepared from the minced lizard fish showed the highest acceptability. Flash fried cutlets were found to be superior in quality compared to raw cutlets. The raw cutlet had storage life of 6 days, 11 weeks and 19 weeks at 4°C, -8°C and -20°C respectively and flash fried cutlets had a shelf life of 22 weeks at -20°C.

Texturised meat from low cost fish

A comparative study of the suitability of five species of fish, namely, threadfin bream (Nemipterous [sic] japonicus), cat fish (Tachysurus fella), ribbon fish (Trichiurus spp.), barracuda (Sphyraena jello) and jew fish (Pseudosciaena spp.) for the production of texturised meat has indicated that all these species are good source for the purpose. Protein content of the final product from all the species was higher than that prescribed for FPC type A. The product had excellent rehydration capacity and firm and elastic texture. No significant difference was observed in the rehydration capacity of the texturised meat from all the species studied. Salt concentration was found to influence the texture and salt content of 1.5 to 2% was found to result in the desirable firm and elastic texture. Rehydration capacity was not influenced to any significant extent by the salt content.

Comparative feature on design, construction and installation of three different model of low cost solar tunnel dryers

The study was conducted in collaboration with the ECFC project of the FAO (BGD/97/017) in Cox's Bazar to develop a low cost solar tunnel dryer for the production of high quality marine dried fish. The study areas were Kutubdiapara, Maheshkhali and Shahparirdip under Cox's Bazar district. Three different models of low cost solar dryer were constructed with locally available materials such as bamboo, wood, bamboo mat, hemp, canvas, wire, nails, rope, tin, polythene and net. Size of the dryers were: 20x4x3 ft ; 30x3x3 ft and 65x3x3 ft with the costs of Tk. 3060, 3530, 9600 for dryer 1, 2 and 3, respectively having different models. The drying capacities were 50, 150, 500 kg for dryer 1, 2 and 3 respectively. The average temperature range inside the dryers were 29-43°C, 34-51°C and 37-57°C for dryer 1, 2 and 3 respectively as recorded at 8:30h to 16:30h. The relative humidity were in the ranges of 22-42%, 27-39% and 24-41 % in dryer 1, 2 and 3 respectively. The fish samples used were Bombay duck, Silver Jew fish and Ribbon fish. The total drying time was in the range of 30-42, 28-38 and 24-34 hours to reach the moisture content of 12.3-14.5, 11.8-14.3, and 11.6-14.1% in dryer 1, 2 and 3 respectively. Among these three fish samples the drying was faster in Silver Jew fish followed by Bombay duck and Ribbon fish in all the three dryer.
