Text i context. El concurs de cinema amateur «JULIUS» (1987-1996)

El «Julius» és un concurs de cinema amateur que fonamenta la seva singularitat en el fet de partir d’un text literari prefixat del qual els participants han de fer una adaptació audiovisual. En aquest article s’estudia la primera època del concurs: el seu origen, les diverses edicions en què es dugué a terme, les incidències que s’hi produïren..., i el context social i cultural que va contribuir a fer-ne un concurs amb unes característiques úniques que es concretaren en l’anomenat «esperit Julius», sorneguer, llibertari i surrealista.

Aplicacions de reconeixement de la parla: sistemes de respeaking III

En aquest projecte es fa una introducció als reconeixedors de la parla, el seu funcionament i la seva base matemàtica. Un cop tots els conceptes han quedat clars, es mostra el mètode de creació que hem seguit per obtenir el nostre propi reconeixedor de la parla, utilitzant les eines HTK, en català. S’avaluen les seves virtuts i els seus defectes a través de diferents proves realitzades als seus components. A més a més, el projecte arrodoneix la feina implementant un sistema de dictat automàtic que explota el reconeixedor de la parla utilitzant Julius.

Evaluation of susceptibility of pear and plum varieties and rootstocks to Ca. P. pyri and Ca. P. prunorum using Real-Time PCR

Real-time PCR was used to quantify phytoplasma concentration in fifty inoculated trees from five Prunus rootstocks and in forty-eight symptomatic pear and Japanese plum trees from orchards. Seasonal fluctuation of Ca. P. prunorum in different Prunus rootstocks, over three years, showed that the highest percentage detected by nested-PCR was in the ‘Garnem’ rootstock on nearly all sampling dates. Intra-varietal differences were also observed. Phytoplasma titer could be estimated by real time PCR in some trees of the rootstocks ‘Garnem’, ‘Barrier’, ‘GF-677’ and ‘Marianna’, and ranged from 4.7x105 to 3.18x109 phytoplasmas per gram of tissue. Quantification by real-time PCR was not possible in the ‘Cadaman’ trees analyzed, probably due to a lower phytoplasma titer in this variety. Samples from infected trees from commercial plots had different phytoplasma concentration and detection percentage depending on the variety, both being lower in ‘Fortune’ and ‘606’ Japanese plum and in ‘Blanquilla’ pear trees.

Evaluation of detection methods for Virus, Viroids and Phytoplasmas affecting pear and apple

The RT-PCR technique for the detection of apple stem grooving virus (ASGV), apple stem pitting virus (ASPV), apple chlorotic leaf spot virus (ACLSV), apple mosaic virus (ApMV) and pear blister canker viroid (PBCV) was evaluated for health control of fruit plants from nurseries. The technique was evaluated in purified RNA and crude extracts and also in phloem collected in autumn and from young spring shoots. The results obtained for phytoplasma detection with ribosomal and non-ribosomal primers are also presented.

Juli Cèsar, tirà i visionari? : l'esfondrament de la República romana

Aquest treball emmarca la vida de Juli Cèsar en el procés d'esfondrament de la República romana i la guerra civil. La seva vida n'és el fil conductor. També hi ha anàlisis descontextualitzades d'aquesta vida (la lluita entre optimates i populares, els mandats extraordinaris, la figura dels tribuns de la plebs i l'imperialisme romà), necessaris per a entendre aquest pas de República a Principat.

Hereditary hepatic and systemic amyloidosis caused by a new deletion/insertion mutation in the apolipoprotein AI gene.

We report a Spanish family with autosomal-dominant non-neuropathic hereditary amyloidosis with a unique hepatic presentation and death from liver failure, usually by the sixth decade. The disease is caused by a previously unreported deletion/insertion mutation in exon 4 of the apolipoprotein AI (apoAI) gene encoding loss of residues 60-71 of normal mature apoAI and insertion at that position of two new residues, ValThr. Affected individuals are heterozygous for this mutation and have both normal apoAI and variant molecules bearing one extra positive charge, as predicted from the DNA sequence. The amyloid fibrils are composed exclusively of NH2-terminal fragments of the variant, ending mainly at positions corresponding to residues 83 and 92 in the mature wild-type sequence. Amyloid fibrils derived from the other three known amyloidogenic apoAI variants are also composed of similar NH2-terminal fragments. All known amyloidogenic apoAI variants carry one extra positive charge in this region, suggesting that it may be responsible for their enhanced amyloidogenicity. In addition to causing a new phenotype, this is the first deletion mutation to be described in association with hereditary amyloidosis and it significantly extends the value of the apoAI model for investigation of molecular mechanisms of amyloid fibrillogenesis.

Obispos y gladiadores: El recurso a los profesionales del anfiteatro en disputas por la elección episcopal.

[spa]La costumbre de enrolar a combatientes del anfiteatro (arenarii) como guardia personal en el marco de luchas faccionales sobrevivió durante el siglo IV. Incluso si en la mayor parte de casos este fenómeno se explica por razones políticas, conocemos dos ejemplos en los que los candidatos a obispo recurrieron a gladiadores para triunfar sobre sus oponentes. El primer ejemplo está relacionado con la elección de Silvano (en el 305 o en el 307/308), quien llegó a hacerse elegir obispo de Cirta (actual Constantine)gracias a la ayuda del arenarius Muto. Esta ayuda quedó bien demostrada por el testimonio de diversas personas durante el proceso seguido contra Silvano en el 320, en el que se reconoció su culpabilidad y se le condenó al exilio. El segundo ejemplo es el del papa Dámaso (366), elegido obispo de Roma en la iglesia de Lucina el mismo día en el que el diácono Ursino era escogido en la basílica de Julio. En el conflicto siguiente, Dámaso convocó a arenarii, quadrigari y fossores, quienes acudieron en su ayuda fuertemente armados. Éstos atacaron la basílica en la que se habían refugiado los partidarios de Ursino y el resultado del asalto fue de 137 muertos. [eng]The habit of engaging fighters of the amphitheatre (arenarii) as a personal guard in the factional struggles survived during the 4th century. Although in most cases it was about political causes, we know two examples where the candidates to be bishops turned to gladiators in order to overcome their opponents. The first example is that of election of Silvanus (305 or 307-308), who got the bishopric of Cirta (the modern Constantine) thanks to the help of the arenarius Mutus. This help was proved by the testimony of several witnesses during the trial which was followed against Silvanus in 320, where his guilt was admitted and he was condemned to the exile. The second exemple is that of the the Pope Damasus (366), elected bishop of Rome in the church of Lucina in the same day as the deacon Ursinus was elected in the basilica of Julius. In the conflict that was to follow, Damasus called arenarii, quadrigarii and fossores who came to help him heavily armed. They attacked the basilica where the supporters of Ursinus had taken refuge and as a result of the assault 137 people died.
