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.

The decision in QCOAL Pty Ltd v Cliffs Australia Coal Pty Ltd [2010] QSC 479 involved an examination of a number of issues relating to the assessment of costs under the Legal Profession Act 2007 (Qld). The decision highlights a range of issues which, in slightly different circumstances, may have deprived the successful party of the right to recover costs by reference to the costs agreement.

Reunião da Mesa da Constituinte discute como será a votação do substitutivo da Sistematização no Plenário geral. Já existem propostas do Centrão e da Mesa. De acordo com o Senador Mauro Benevides (PMDB-CE), presidente em exercício da Assembleia Nacional Constituinte (ANC), a Mesa se encaminhará para a apresentação de outro substitutivo. Sessão solene conclui os trabalhos da Comissão de Sistematização dando por encerrada a votação do substitutivo, este encaminhado à Mesa da ANC. O Deputado Bernardo Cabral (PMDB-AM), faz considerações sobre os trabalhos da Comissão de Sistematização. O Senador Affonso Arinos (PFL-RJ) repete a frase de Benjamin Franklin: "Por haver vivido muito, fui levado a mudar de opinião várias vezes em assuntos importantes, assim aceito este projeto" e conclui declarando aceitar o projeto. O Deputado Amaury Muller (PDT-RS) afirma que embora os Constituintes façam um balanço positivo dos assuntos que foram tratados na Sistematização, reconhecendo seu trabalho, mantém-se a fé e a esperança de que os Constituintes no Plenário possam traduzir com fidelidade os compromissos que assumiram com a sociedade brasileira durante a campanha eleitoral. O Senador Mario Covas (PMDB-SP), a Deputada Sandra Martins Cavalcanti (PFL-RJ) e o Deputado Arnaldo Faria de Sá (PTB-SP) consideram que no Plenário alguns dos pontos do substitutivo serão reformados, enriquecendo o texto. O Deputado Carlos Sant'anna (PMDB-BA) ressalta a necessidade de alterações em questões formais como a língua, a estrutura e a harmonia do texto. O Deputado Luiz Inácio Lula Da Silva (PT-SP) espera que o projeto tenha melhorias no Plenário, pois a sociedade brasileira está na expectativa de que esta Constituição possa retratar sua luta nos últimos anos. O Senador Fernando Henrique Cardoso (PMDB-SP) crê que o resultado dos trabalhos será uma Constituição democrática e moderna.
