In-situ procjena zidanih svodova: Dinamička ispitivanja i numerička analiza

This paper concerns the structural identification of historical masonry buildings with reference to a case study, which is discussed in detail. The building is located in Southern Italy (Lecce). It has an ancient vaulted roof that is complex and commonly found in old masonry structures. This study takes advantage of extensive historical and structural investigations of the building. Preliminary activities have been conducted to obtain information about the current state of the structure including the geometry, morphology, structural details, material properties, prior interventions, and existing damage. This process was supported by an historical investigation into the conceptual background and construction methods used to build the structure. After the historical investigation, a series of experiments, including dynamic tests, were conducted on a number of the vaults to determine their dynamic response characteristics under operational conditions. A numerical model was also determined. In this paper, the primary dynamic test results and modelling assumptions are reported. Comparisons between numerical and experimental results are discussed.U ovom se članku razmatra konstrukcija jedne kulturno-povijesne zidane zgrade, detaljno obrađena još u jednoj ranijoj studiji. Zgrada se nalazi u Južnoj Italiji (Lecce). Zgrada ima složenu konstrukciju krova, sa svodovima, kakva je česta kod starih zidanih zgrada. U članku se uzimaju u obzir ranija opsežna povijesna i statička istraživanja. Ta ranija istraživanja bila su usmjerena ka dobivanju informacija o prethodnim ispitivanjima te o sadašnjem stanju konstrukcije, uključujući geometrijske karakteristike, oblikovnost, konstruktivne detalje, svojstva materijala i oštećenja zgrade. Pri tome su pomogla i ranija istraživanja o koncepciji i načinu gradnje zgrade. Nakon ovih istraživanja, obavljene su serije ispitivanja, između ostalog i dinamički pokusi na mnogim svodovima da se ustanove svojstva njihovog dinamičkog odziva u uvjetima standardne uporabe. Postavljen je i numerički model. U ovom su članku prikazani rezultati prvih dinamičkih ispitivanja i svojstava modela. Diskutira se odnos rezultata dobivenih numerički i eksperimentalno

Determinación de la edad y el crecimiento por esclerocronología en la tortuga boba marina Caretta caretta del mar Mediterráneo

Skeletochronology was applied to humerus bones to assess the age and growth rates of loggerhead sea turtles (Caretta caretta) in the Mediterranean Sea. Fifty-five dead turtles with curved carapace lengths (CCL) ranging from 24 to 86.5 cm were collected from the central Mediterranean. Sections of humeri were histologically processed to analyze annual growth marks. Two approaches were used to estimate the somatic growth in the form of a von Bertalanffy growth function. The first approach was based on calculating the total number of growth marks, which corresponds to the age of turtles at death. The second approach estimates the carapace length at old growth marks in order to provide the growth rate of each turtle. The observed individual growth rates ranged from 1.4 to 6.2 cm yr–1, and showed both elevated inter- and intra-individual variability possibly related to the environmental variability experienced by turtles during their lifetime. Both approaches gave similar results and suggest that Mediterranean loggerhead turtles take 14.9 to 28.5 years to reach a CCL of 66.5 to 84.7 cm. This size corresponds to the average size of nesting females found in the most important Mediterranean nesting sites and can be considered the approximate size at maturity.La esclerocronología se aplicaba a los huesos de los húmeros para determinar la edad y las tasas de crecimiento de la tortuga boba Caretta caretta del Mediterráneo. Cincuenta y cinco tortugas bobas muertas de 24 a 86.5 cm de longitud de la curvatura del caparazón (CCL) fueron recogidas del Mediterráneo central. Secciones de los húmeros fueron procesados histológicamente para analizar las marcas anuales de crecimiento. Se aplicaron dos aproximaciones para determinar el crecimiento somático utilizando la función de crecimiento de von Bertalanffy. La primera aproximación se basaba en el número total de marcas de crecimiento, correspondiendo a la edad de las tortugas en el momento de la muerte. La segunda aproximación era una estimación de la longitud del caparazón en las marcas de crecimiento más antiguas, con la intención de saber la tasa de crecimiento de cada tortuga. Las tasas de crecimiento individual observadas, oscilaban entre 1.4 y 6.2 cm año–1, mostrando una elevada diversidad individual intra e interanual, posiblemente ligada a la variabilidad ambiental experimentada por las tortugas bobas durante su vida. Ambas aproximaciones dieron resultados similares y sugieren que la tortuga mediterránea tarda 14.5-28.5 años en alcanzar un tamaño de 66.5-84.7 cm de CCL. Este tamaño corresponde al tamaño medio de las tortugas bobas hembras nidificantes, encontradas en la mayoría de lugares nidificantes del Mediterráneo y puede ser considerado el tamaño aproximado de la madurez

Stanislavskij’s Method Improves Personality Aspects in Pre-adolescents

In Stanislavskij’s method, emotions are produced through body actions, where the body is the custodian of the actions associated with emotions. This association could improve some aspects of personality. Everyone can feel themselves in an immediate way. Hence, an increased knowledge of emotions and thoughts can improve the relationship with others. In the current study, 74 boys and girls took part in a research to ascertain if participation to a workshop on Stanislavskij’s method can improve some personality aspects, according to the Big Five theory. The workshop was divided into two stages: (1) subjects were invited to tell a story with their body, sounds, and in narration; (2) discovering the places of Carloforte island. The final event was a personal rendering of the experience. The six-month experiment included three weekly meetings of three hours each. On the first day, the BFC was administered to each subject and re-administered on the last day of the experiment. Results showed that Energy, Friendship and Openness factors improve after the workshop. This can be explained by the Stanislavskij’s method enabling subjects to feel emotions and handle conflicts immediately through the body and the use of actions.&nbsp;&nbsp;&nbsp

Sociedade da transparência

A obra é apresentada ao leitor em nove capítulos que vão da sociedade positiva (capítulo 1), passando pelo emaranhado da produção cultural da sociedade da exposição (capítulo 2), seguindo para a sociedade da evidência, sociedade pornográfica, sociedade da aceleração, sociedade da intimidade, sociedade da informação, sociedade do desencobrimento até culminar no capítulo final, sociedade do controle. Trata-se de um livro de bolso com 120 páginas, de linguagem acessível e didática, que retrata os saberes alicerçados na própria natureza política da vida em sociedade. O excesso de positividade da vida reflete um sistema fechado em si mesmo, que impõe o igual e anula o diferente e as contradições nas quais nós vivemos, excluindo a dimensão relacional, contextualizada e crítica dos processos de (re)conhecimento humano
