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.

Terminou a votação do capítulo referente ao Poder Judiciário. Foi votado o artigo que trata da função do advogado. Ficou assim a redação do artigo 158: O advogado é indispensável a administração da Justiça, sendo inviolável por seus atos e manifestações nos limites da lei, no exercício da profissão. Um dos pontos mais polêmicos do capítulo do Poder Judiciário foi o tratou da estatização dos cartórios. Prevaleceu no texto da futura Carta o caráter privado dos cartórios. Outro ponto polêmico foi o que criava o Tribunal Constitucional, uma inovação que não foi aprovada. Houve um esforço para se modernizar o Poder Judiciário. Começou a ser examinado o capítulo que trata das funções do Ministério Público.

We estimate the incidence of cystic fibrosis in Ireland to be at least 1 case per 1838 live births. We have analysed DNA from 44 Irish CF patients for the presence of deletion 508, using the polymerase chain reaction. The deletion was found in 76% of their chromosomes, and approximately 58% of the patients are homozygous for this deletion. Our results are not significantly different from those found in Canadian or UK patient populations, in which frequencies are higher than those found in Southern European countries.
