Afonso de Ulloa, escritor espanhol, nasceu em Zamora na primeira metade do século XVl e morreu em Veneza, Itália, em 1580. Filho de Francisco de Ulloa, oficial que esteve na África com Carlos V, seguiu também a carreira das armas, estabelecendo-se depois em Veneza. Desempenhou várias missões diplomáticas, escreveu muitas obras e traduziu para o italiano, língua que conhecia tanto quanto a materna, autores espanhóis e portugueses. Quanto à obra Vita, et fatti dell' invitissimo imperatore Carlo Qvinto.. . sabe-se que foi pela primeira vez impressa em Veneza em 1560 por Vincenzo Valgrisio e que foi muitas vezes reeditada. Salvo pela época, a edição supra referenciada não oferece grande interesse artístico, mas há uma interessante gravura com a efígie de Carlos V.

En la sociedad actual, el ejercicio físico se considera un factor determinante para la consecución de una vida saludable. Gracias a los avances tecnológicos y la constante evolución del conocimiento de la actividad física y sus beneficios, la sociedad, en general, goza de numerosas facilidades a la hora de poder realizar cualquier actividad física que genere una mejoría para uno mismo. Pero, a pesar de ello, hay rincones de la sociedad a los que los beneficios del ejercicio no han llegado aún . En el siguiente proyecto estudiaré, por una parte, e lrégimen de aislamiento de los centros penitenciarios; a su vez, profundizaré en los perjuicios que puedan sufrir los internos en este régimen, y en los beneficios que pueda tener el ejercicio físico en los reclusos que sufren el aislamiento. Por último, propondré un programa de ejercicio, que a su vez pueda compenetrarse con el reglamento penitenciario, buscando los beneficios del ejercicio para las personas que se encuentren en esta situación.

The synthesis and direct observation of 1,1-di-tert-butyldiazene (16) at -127°C is described. The absorption spectrum of a red solution of 1,1-diazene 16 reveals a structured absorption band with λ max at 506 run (Me_2O, -125°C). The vibrational spacing in S_1 is about 1200 cm^(-1). The excited state of 16 emits weakly with a single maximum at 715 run observed in the fluorescence spectrum (Me_2O:CD_2Cl_2, -196°C). The proton NMR spectrum of 16 occurs as a singlet at 1.41 ppm. Monitoring this NMR absorption at -94^0 ± 2°C shows that 1,1-diazene 16 decomposes with a first-order rate of 1.8 x 10^(-3) sec(-1) to form isobutane, isobutylene and hexarnethylethane. This rate is 10^8 and 10^(34) times faster than the thermal decomposition of the corresponding cis and trans 1,2-di-tert-butyldiazene isomers. The free energy of activation for decomposition of 1,1-diazene 16 is found to be 12.5 ± 0.2 kcal/mol at -94°C which is much lower than the values of 19.1 and 19.4 kcal/lmole calculated at -94°C for N-(2,2,6,6- tetramethylpiperidyl)nitrene (3) and N-(2,2,5,5- tetrarnethylpyrrolidyl)nitrene (4), respectively. This difference between 16 and the cyclic-1,1-diazenes 3 and 4 can be attributed to a large steric interaction between the tert-butyl groups in 1,1-diazene 16.

In order to investigate the nature of the singlet-triplet gap in 1,1-diazenes, 2,5-di-tert-butyl-N-pyrrolynitrene (22) was generated but was found to be too reactive towards dimerization to be persistent. In the presence of dimethylsulfoxide, however, N-pyrrolynitrene (22) can be trapped as N-(2,5-di-tert-butyl- N'-pyrrolyl)dimethylsulfoxirnine (38). N-(2,5-di-tert-butyl-N'-pyrrolyl)dimethylsulfoximine (38-d^6) exchanges with free dimethylsulfoxide at 50°C in solution, presumably by generation and retrapping of pyrrolynitrene 22.

Megacyclops viridis Jurine, noticed in Lago Maggiore in 1912 by De Marchi from the littoral vegetation of Pallanza, is a normal member of the littoral plankton of the lake. The subgenus Megacyclops, created by Kiefer in his revision of the viridis-vernalis group, contains european and american species some of which are today considered as varieties of the species viridis. This paper examines morphology and of the distribution of the Italian viridis in Lake Maggiore.

Eudiaptomus vulgaris Schmeil is the most abundant copepod in Lake Maggiore and forms also, in respect to other entomostraca, the most important element, through its average biomass and because it is fairly numerous throughout the year. Plankton samples collected in a systematic and quantitative way, gave the opportunity to study some aspects of the dynamics of the population of this copepod, in safety in view of the uncertainty which in this kind of study can ensue when samples are taken only at a single station - in consequence of the changes in size of population between different water masses. The results of the biometrical observations are of the population of Eudiaptomus vulgaris is presented.

El propósito de este trabajo de fin de grado es realizar un análisis acerca del efecto de la crisis actual sobre las entidades sin fines lucrativos. Las entidades del Tercer Sector, al igual que las entidades tanto del sector público como privado, se han visto fuertemente afectadas por la crisis que se atraviesa desde 2008. Los efectos de la crisis se han podido ver reflejados en distintos aspectos de las entidades sin ánimo de lucro, pero entre los más importantes se encuentran la dificultad de obtener financiación, y el fuerte aumento de la demanda de este sector, debido a que las personas o colectivos que se han visto afectados han acudido a estas entidades para buscar ayuda. Con lo que respecta a la financiación previa a la crisis, la gran mayoría de las entidades no lucrativas venían siendo financiadas por el sector público, lo cuál ha supuesto un gran problema ya que toda esa financiación pública se ha visto reducida a causa de la crisis, y por tanto estas entidades tienen que esforzarse en captar financiación privada. Para que la obtención de esta financiación sea más fácil se recomienda que la información que suministran estas entidades sea transparente y así se genere confianza. El aumento de la demanda de este sector está provocando en las entidades sin ánimo de lucro la prioridad de la cobertura de las necesidades básicas de los individuos.

Zooplankton was studied in four alpine lakes in Switzerland, France and Italy. The presence the presence of the invertebrate predator Heterocope in three lakes was stated. It is then discussed why in three of these four lakes, the copepod Arctodiaptomus denticornis is present in the absence of Arctodiaptomus bacillifer, and vice versa respectively in the second and first parts of the lacustrine summer.

In recent times, some specialists have begun to study the subject of food selection of fish in an organized way, thus highlighting its importance. In the present work, the author intends to evaluate the impact of predation on the eupelagic zooplanktonic biocenosis of Lake Maggiore, producing, in this way, as far as possible, a basis for a better understanding of the population dynamics of the species of zooplankton directly involved. Another aspect which has been studied is that related to the mechanism of selective capture set in action by the predator. To this end the study tries to bear in mind that the subject should be interpreted as a function of numerous factors acting contemporaneously, that is as the interaction of characters peculiar to the predator and to the prey. The species studied, locally called ”bondella”, belongs to the family Salmonidae, subfamily Coregoninae and was introduced into Lake Maggiore in 1950.

In freshwater environments of modest size and without notable ecological structure, there is usually present only one diaptomid species. When two or more diaptomid species are present in the same habitat, generally their body dimensions are distinctly different. There are only four examples of co-existence of Arctodiaptomus bacillifer (Koelb.) and Acanthodiaptomus denticornis (Wierz.) situated at higher altitudes alpine lakes. The article discusses the results of sampling in the summer of 1953 and the problem of the co-existence of Arctodiaptomus bacillifer, Acanthodiaptomus denticornis and Heterocope saliens.
