Documentation, profile descriptions and analytical results of loes profiles from Bavaria, southern Germany

This study investigates the landscape evolution and soil development in the loess area near Regensburg between approximately 6000-2000 yr BP (radiocarbon years), Eastern Bavaria. The focus is on the question how man and climate influenced landscape evolution and what their relative significance was. The theoretical background concerning the factors that controlled prehistoric soil erosion in Middle Europe is summarized with respect to rainfall intensity and distribution, pedogenesis, Pleistocene relief, and prehistoric farming. Colluvial deposits , flood loams, and soils were studied at ten different and representative sites that served as archives of their respective palaeoenvironments. Geomorphological, sedimentological, and pedological methods were applied. According to the findings presented here, there was a high asynchronity of landscape evolution in the investigation area, which was due to prehistoric land-use patterns. Prehistoric land use and settlement caused highly difIerenciated phases of morphodynamic activity and stability in time and space. These are documented at the single catenas ofeach site. In general, Pleistocene relief was substantially lowered. At the same time smaller landforms such as dells and minor asymmetric valleys filled up and strongly transformed. However, there were short phases at many sites, forming short lived linear erosion features ('Runsen'), resulting from exceptional rainfalls. These forms are results of single events without showing regional trends. Generally, the onset of the sedimentation of colluvial deposits took place much earlier (usually 3500 yr BP (radiocarbon) and younger) than the formation of flood loams. Thus, the deposition of flood loams in the Kleine Laaber river valley started mainly as a consequence of iron age farming only at around 2500 yr BP (radiocarbon). A cascade system explains the different ages of colluvial deposits and flood loams: as a result of prehistoric land use, dells and other minor Pleistocene landforms were filled with colluvial sediments. After the filling of these primary sediment traps , eroded material was transported into flood plains, thus forming flood loams. But at the moment we cannot quantify the extent ofprehistoric soil erosion in the investigation area. The three factors that controlled the prehistoric Iandscapc evolution in the Ioess area near Regensburg are as follows: 1. The transformation from a natural to a prehistoric cultural landscape was the most important factor: A landscape with stable relief was changed into a highly morphodynamic one with soil erosion as the dominant process of this change. 2. The sediment traps of the pre-anthropogenic relief determined where the material originated from soil erosion was deposited: either sedimentation took place on the slopes or the filled sediment traps of the slopes rendered flood loam formation possible. Climatic influence of any importance can only be documented as the result of land use in connection with singular and/or statistic events of heavy rainfalls. Without human impact, no significant change in the Holocene landscape would have been possible.

Comentario a la sentencia de la Rota Romana del 27/10/2006, Coram R. P. D. Mauricio Monier, ponente prot. N. 17.557 – sent. 136/06

Introducción: La presente Sentencia contempla la nulidad de un matrimonio en que las partes tuvieron un noviazgo de más de cuatro años y una convivencia matrimonial de dos años y medio, en la que no hubo hijos. La separación de las partes definitiva tuvo lugar porque el convenido era incapaz de instalar una vida verdaderamente conyugal. Se me solicita un comentario a esta Sentencia, publicada en su texto original latino y en su traducción castellana, cuando ya existe un breve, pero medular y excelente comentario del Revdo. Mons. Dr. Alejandro W. Bunge, Juez de la Rota, publicado en el libro “Pius et Prudens”, con el título de “Una Sentencia integradora”1. Además, el indicado comentario, se encuentra en el contexto de un generoso elogio a la persona de quien suscribe por la preocupación acerca de la indebida omnipresencia de las causas psíquicas de nulidad matrimonial en los Tribunales eclesiásticos, cuando muchas veces es más ajustada a la verdad y se deberían tener en cuenta, las causas éticas, concretamente las exclusiones de algunos de los fines o de las propiedades esenciales del matrimonio que tiene lugar por parte de los cónyuges...

Diário da Constituinte [gravação de vídeo] : [programa n. 136 A]

Descrição do Projeto Nhundiaquara, uma experiência de reforma agrária no município de Morretes, no litoral do Paraná, baseada na distribuição de terras de uma antiga usina de açúcar. Assentados falam das suas terras e do trabalho. A assistência aos assentados é feita pela ACARPA (Associação de Crédito e Assistência Rural do Paraná), cujos técnicos fornecem sementes, ensinam técnicas de cultivo e dão apoio financeiro. Apresentação de dados sobre projetos de assentamentos criados pelo INCRA no Brasil. Assentados acreditam na reforma agrária e pedem aos deputados e senadores da Assembleia Nacional Constituinte (ANC) melhores condições de trabalho aos colonos.

Diário da Constituinte [gravação de vídeo] : [programa n. 136]

Proibir a fabricação de armas nucleares no Brasil e preservar as terras indígenas são as principais reivindicações dos cientistas à Assembleia Nacional Constituinte (ANC). Reunidos na 39ª Reunião Anual da Sociedade Brasileira para o Progresso da Ciência (SBPC), os pesquisadores querem debater suas propostas com os constituintes. Carolina Bori, Presidente da SBPC quer apresentar as propostas da SBPC, que não interessam só aos cientistas, mas à sociedade brasileira. A SBPC vai enviar duas proposta de emendas populares. O Reitor da USP José Goldemberg é contra a fabricação de armas nucleares no país. Os cientistas querem também a manutenção da proposta que dá poderes somente ao Congresso Nacional para autorizar a mineração nos territórios indígenas. Manuela C. da Cunha, Presidente da Associação Brasileira de Antropologia, defende que somente a União tenha o privilégio da pesquisa e lavra em áreas indígenas. Wanderlino T. da Carvalho, Presidente da Coordenação Nacional de Geólogos, propõe que as terras indígenas se tornem reservas nacionais de minérios, cuja exploração não é urgente para as necessidades do país no momento. Aílton Krenak, representante da União das Nações Indígenas, afirma que as comunidades indígenas querem ter o direito de esboçar um projeto próprio de futuro e que deverão ter assegurado o direito à terra e aos recursos naturais nela existentes . A Comissão de Sistematização discute o pedido de anulação da aprovação do projeto que proíbe a conversão da dívida externa em investimento de capital estrangeiro no país. O Líder do Governo Carlos Sant'Anna (PFL-BA) diz que a matéria é assunto do Congresso e não da Constituinte. Paulo Ramos (PMDB-RJ), autor do projeto, discorda.

On the feeding of freshwater ostracods. [Translation of: Zoologicheskij zhurnal, 27(2), 1948, 125-136]

The present work appertains to a series of investigations in the field of trophodynamics of water bodies conducted by the department of hydrobiology ”Mosrybvtuza” under the leadership of Prof. Director N.S. Gaevska. Usually with quantitative collections of benthos ostracoda are hardly taken account of. But with the employment of special methods it is possible to be convinced that they are encountered in massive numbers. The role of ostracods in the nutrition of fish is recognised as important by many authors. On the question of the feeding of ostracods, in the literature there are only the fragmentary indications about the occurrence in the gut of ostracods of algae (diatoms, desmids) and detritus. The study of the feeding of ostracods was conducted both by the method of dissecting the guts of ostracods taken from natural waters, and by the method of feeding ostracods under laboratory conditions with a variety of food objects. Moreover, with a view to revision of obtained quantitative data, for determination of food requirements of ostracods the respiration method was applied.
