Fecundity of crab Hepatus-pudibundas (herbst, 1785) (crustacea, decapoda, calappidae) in Ubatuba (SP), Brazil

The egg number and the rate in which they are produced constitute important informations for the comprehension of the reproductive process. The egg number carried by a female crab is related to a body dimension (carapace width or length). These data are adjusted to a linear regression. The specimens of Ii. pudibundus were collected in Ubatuba region, Brazil during the period from January 1991 to July 1993. In this paper 30 females with eggs in the initial embryonic phase were used to estimate ther egg number. The mean fecundity obtained was 75,615 +/- 30,120 eggs/female/spawn. Although the H. pudibundus fecundity was not high, it can be inferred that the larval survival in nature should be large, because it is one of the most abundant crabs in the studied area.

Weight width carapace relationship in the crab hepatus-pudibundus (herbst, 1785) (crustacea, decapoda, calappidae) of the Ubatuba region, SP, Brazil

In populational studies, the weight/width carapace relationship analysis, can furnish indications about the individual physiological variations as a function of the environment, and it can indicate sexual dimorphism. The goal of this research is to find the mathematical expressions of weight/width carapace relationship in the crab Hepatus pudibundus. This study was accomplished by analysing the crabs that were sampled monthly with a shrimp fishing boat equipped with 2 otter-trawl nets, during the period from november/1988 to october/1989. A total of 624 specimens were obtained composed of 244 males and 380 females. In each group the sex, the weight (PE) and the carapace width (LC) were determined. The obtained values agree with the studied range, showing variations during male and female development, represented by the potential function of the equation Y = aX(b). Such variations are probably related to reproductive strategies.

Appraisal of the chelipeds size on Hepatus-pudibundus (Herbst, 1785) (Crustacea, Calappidae) in function of sex and maturation

This paper appraises the influence of chelipeds on sexual and maturation phasis of the crab Hepatus pudibundus (Herbst, 1785), collected in Ubatuba (SP) region. The allometric constants obtained from the regression (carapace width X cheliped weight) adjusted to a power function (Y=aX(b)) were analysed. It was verified that males show larger chelipeds than females. The mean percentage of the chelipeds weight differs in sex and maturation.

Gli infortuni sul lavoro in Brasile. Studio nello Stato di San Paolo del Brasile, regione di Botucatu, utilizzando il metodo dell'albero delle cause

This paper discusses, within the prevaling Brazilian situation, the possibility of applying 'Causal Tree' (CT) method in investigating occupational accidents by safety personnel in the public health services and workers' unions. The method was developed during the seventies in France, for use by plant safety personnel. The authors used this method in Botucatu, State of Sao Paulo, Brazil, in order to investigate 40 serious occupational accidents that occurred in industrial plants during the second half of 1993, that had been registered by Social Security. In these cases, the predominance of situations in which the lack of safety measures were identified by inspection indicates that in most instances, the use of CT is unnecessary. However, the authors discuss its use by safety personnel from the public health services and workers' unions to investigate certain accidents to contribute to the knowledge base and help overcome the cultural based guilt which, in Brazil, has turned the victim into the person responsible for the accident.

Teorie e immagini del governo "misto" nel Cinquecento: i casi di Gasparo Contarini, Donato Giannotti, Paolo Paruta e Traiano Boccalini

This doctoral dissertation faces the debated topic of the traditions of Republicanism in the Modern Age assuming, as a point of view, the problem of the "mixed" government. The research therefore dwells upon the use of this model in Sixteenth-Century Italy, also in connection with the historical events of two standard Republics such as Florence and Venice. The work focuses on Donato Giannotti (1492-1573), Gasparo Contarini (1483-1542) and Paolo Paruta (1540-1598), as the main figures in order to reconstruct the debate on "mixed" constitution: in them, decisive in the attention paid to the peculiar structure of the Venetian Republic, the only of a certain dimension and power to survive after 1530. The research takes into account also the writings of Traiano Boccalini (1556-1613): he himself, though being involved in the same topics of debate, sets for some aspects his considerations in the framework of a new theme, that of Reason of State.

L' "opera mondo" di Paolo Volponi fra satira e morale

Nella mia tesi di dottorato mi propongo di indagare la metamorfosi del romanzo nella letteratura italiana contemporanea attraverso il lavoro di Paolo Volponi, che può essere descritto come un’«opera mondo», in accordo con la formula critica coniata da Franco Moretti. Volponi intende superare il divario fra l’io e il mondo e ricomporre il corpo come una mediazione umanistica di ragione e sensi. La sua opera può essere definita ‘epica’ perché recupera la tradizione del romanzo cavalleresco e la parodia esercitata su questa tradizione letteraria da Cervantes nel Don Chisciotte. Ma, come l’Ulysses di Joyce, è un’epica «moderna» perché fondata su una totalità disgiunta e sul conflitto dialogico, in una linea che accomuna la moltiplicazione dei punti di vista, propria del romanzo polifonico secondo Bachtin, alla pluralità di prospettive del discorso scientifico. Dopo un primo capitolo teorico, nel secondo e nel terzo capitolo della tesi i romanzi di Volponi vengono studiati in rapporto al filone dell’«epica moderna» e al genere satirico, che ha un suo modello fondativo nell’opera di Giacomo Leopardi. Il quarto capitolo si focalizza sulle ultime raccolte poetiche, che mostrano la tendenza a recuperare il linguaggio formulare e la matrice orale della poesia delle origini, servendosene per rappresentare in funzione contrappuntistica l’universo globale dell’età contemporanea.
