Resumen: En esta conferencia quiero presentar evidencia de una vinculación entre la vigorosa reconfiguración de la fuga llevada a cabo por Anton Reicha en la década de 1790 y las fuerzas culturales e intelectuales desatadas por la Revolución Francesa.

El autor plantea la cuestión de lo significativo del lenguaje teológico a partir del concepto de experiencia en el pensamiento del cardenal Newman. Su itinerario de fe y conversión, enraizado en un diálogo personal con Dios, le ha dado tanto a su teología como a su predicación, un atractivo que trasciende su época y que puede servir de estímulo actualmente en la comunicación teológica.

During the research that it is summarized in the present memory, the activation of enals via iminium ion catalysis in different transformations has been studied. Firstly, a 1,3-dipolar cycloaddition between stable azomethine ylides and a,b-unsaturated aldehydes catalyzed by a chiral imidazolidinone derivative has been optimized. Employing this methodology we have synthesized a large range of densely substituted pyrroloisoquinolines and pyrrolophthalazines with good yields and high values of diastereo- and enantioselectivity. Moreover, a mechanistic study has been carried out based on DFT calculations and experimental data which have allowed us to propose that the (3+2) cycloaddition reaction follows a sequential Michael addition/Mannich cyclization pathway. The formation of the iminium ion as a result of the condensation between the a,b-unsaturated aldehyde and the catalyst plays an essential role, regarding both reactivity and stereoselectivity. On the other hand we have developed a methodology to carry out a cascade Michael/Henry reaction followed by a sequential dehydration. Starting from simple substrates (2-nitromethylacrilates and a,b-unsaturated aldehydes) and employing a prolinol-derivative catalyst a series of quiral nitrocyclohexadienes have been synthesized.

The most important aim of this study lay in filling in the great gap in our knowledge of the processes of germination in the Ceratium cyst and the early developmental stages in the standing stock of Ceratium hirundinella. contained rich cysts, we now succeeded extraordinarily well in pursuing the consistent development of Ceratium from the cyst to the completed cell. A series of experiments were carried out on the cysts and the juvenile stages of Ceratium, which showed very interesting results. The author presents in a general descriptive part the normal processes of germination in Ceratium cysts and the development of the juvenile stages in order to show in an experimental part the changes in form of C. hirundinella under the influence of temperature, light and varying salinities.

O propósito desta dissertação é analisar o período no qual Almeida Garrett esteve em Bruxelas (1834-1836) como Encarregado de Negócios Estrangeiros e Cônsul Geral de Portugal. Para isso, serão tomadas como base as obras Garrett Memorias Biographicas (1881-1884) de Francisco Gomes de Amorim e A Lua de Bruxelas (2000) de Amadeu Lopes Sabino. Estas obras apresentam as dificuldades financeiras de Garrett, devido ao desprezo do governo português. A biografia é marcada pelo discurso moldado de Amorim, por causa da forte relação de amizade que teve com Garrett, sendo este seu pai literário. Já Sabino apresenta um romance centrado nessa temporada, misturando narrativa histórica, dados biográficos e ficção. Dessa forma, neste trabalho, os discursos serão comparados, explicitando o tom específico de cada um: ambos apresentam as relações do intelectual com o país e com a sociedade, em uma época de grandes mudanças; porém, Amorim guarda um certo verniz e silencia sobre alguns acontecimentos, principalmente relacionados ao casamento de Garrett. Sabino tem, nesse relacionamento com a esposa (Luísa Midosi), o teor do seu romance documentado, se pautando exatamente a partir do que Amorim deixa como enigma

John Otterbein Snyder (1867–1943) was an early student of David Starr Jordan at Stanford University and subsequently rose to become an assistant professor there. During his 34 years with the university he taught a wide variety of courses in various branches of zoology and advised numerous students. He eventually mentored 8 M.A. and 4 Ph.D. students to completion at Stanford. He also assisted in the collection of tens of thousands of fish specimens from the western Pacific, central Pacific, and the West Coast of North America, part of the time while stationed as “Naturalist” aboard the U.S. Fish Commission’s Steamer Albatross (1902–06). Although his early publications dealt mainly with fish groups and descriptions (often as a junior author with Jordan), after 1910 he became more autonomous and eventually rose to become one of the Pacific salmon, Oncorhynchus spp., experts on the West Coast. Throughout his career, he was especially esteemed by colleagues as “a stimulating teacher,” “an excellent biologist,” and “a fine man.

The Philippine Expedition of 1907-10 was the longest and most extensive assignment of the Albatross's 39-year career. It came about because the United States had acquired the Philippines following the Spanish-American War of 1898 and the bloody Philippine Insurection of 1899-1902. The purpose of the expedition was to surbey and assess the aquatic resources of the Philippine Islands. Dr. Hugh M. Smith, the Deputy Commissioner of the U.S. Bureau of Fisheries, was the Director of the Expedition. Other scientific participants were Frederick M. Chamberlain, Lewis Radcliffe, Paul Bartsch, Harry C. Fasset, Clarence Wells, Albert Burrows, Alvin Seale, and Roy Chapman Andrews. The expedition consisted of a series of cruises, each beginning and ending in Manila and exploring a different part of the island group. In addition to the Philippines proper, the ship also explored parts of the Dutch East Indies and areas around Hong Kong and Taiwan. The expedition returned great quantities of fish and invertebrate speciments as well as hydrographic and fisheries data; most of the material was eventually deposited in the Smithsonian Institution's National Museum of Natural History. The fisehs were formally accessioned into the museum in 1922 and fell under the car of Barton A. Bean, Assistant Curator of Fishes, who then recruited Henry W. Fowler to work up the material. Fowler completed his studies of the entire collection, but only part of it was ever published, due in part to the economic constraints caused by the Depression. The material from the Philippine Expedition constituted the largest single accession of fishes ever received by the museum. These speciments are in good condition today and are still being used in scientific research.
