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.

Diário da Constituinte [gravação de vídeo] : [programa n. 225]

Adiado o prazo de entrega do substitutivo, devido a falta de consenso nos temas: reforma agrária e sistema de governo. O Deputado Euclides Scalco (PMDB-PR), vice-líder do PMDB, declara que as negociações continuam. O Relator Bernardo Cabral quer evitar o conflito, para que a Constituição seja concluída este ano. O parlamentarismo é maioria entre os constituintes. Apresentação de estatística sobre a posição dos constituintes em relação ao sistema de governo. O Senador José Fogaça (PMDB-RS) explica a proposta de parlamentarismo adotado de forma gradual. O líder do PFL, Deputado Alceni Guerra (PFL-PR), deseja o apoio do Presidente José Sarney para o parlamentarismo. O Presidente da Assembleia Nacional Constituinte - ANC, Deputado Ulysses Guimarães informa que o número de temas polêmicos diminuíram. O líder do PDC, Deputado Siqueira Campos (PDC-GO), o vice-líder do PTB, Deputado Roberto Jefferson (PTB-RJ) e o líder do PDS, Deputado Amaral Netto (PDS-RJ) aprovam o adiamento. O líder do PFL, Deputado José Lourenço (PFL-BA) concorda com a prorrogação. O líder do PT, Deputado Luiz Inácio Lula da Silva (PT-SP) considera que a prorrogação permite que os dirigentes sindicais façam pressão para colocar no relatório as reivindicações dos trabalhadores.

Dark brown sediment with sub-angular to sub-rounded grains, that range from small to medium in size. Lineations with fractured grains are abundant, and grain crushing can also be seen. Minor rotation can also be seen.

Limits on Spin-Dependent WIMP-Nucleon Cross Sections from 225 Live Days of XENON100 Data

We present new experimental constraints on the elastic, spin-dependent WIMP-nucleon cross section using recent data from the XENON100 experiment, operated in the Laboratori Nazionali del Gran Sasso in Italy. An analysis of 224.6 live days x 34 kg of exposure acquired during 2011 and 2012 revealed no excess signal due to axial-vector WIMP interactions with Xe-129 and Xe-131 nuclei. This leads to the most stringent upper limits on WIMP-neutron cross sections for WIMP masses above 6 GeV/c(2), with a minimum cross section of 3.5 x 10(-40) cm(2) at a WIMP mass of 45 GeV/c(2), at 90% confidence level.

225 Jahre Naturforschende Gesellschaft in Bern

Ein Überdauern von 225 Jahren ist eine lange Zeit, in der viel Wasser die Aare hinuntergeflossen ist – «Wasser bewegt», so das Motto unseres Jubiläumsjahres. In dieser Zeit war und ist die NGB einem kontinuierlichen Wandel der wissenschaftlichen Tätigkeiten, aber auch des gesellschaftlichen Umfelds unterworfen. Der folgende Artikel soll einen kurzen Überblick über die Entstehungsgeschichte und die Entwicklung der NGB in diesen 225 Jahren liefern. Als wichtigste Grundlagen dienten beim Recherchieren die bereits bestehenden Zusammenfassungen zum 100-, 150- und 200-jährigen Bestehen der NGB (siehe Referenzliste). Auch die in den «Mitteilungen» publizierten Jahresberichte der Präsidenten stellten wichtige Zeitzeugnisse dar, welche exemplarisch konsultiert und da und dort mit eingearbeitet wurden. Daneben finden sich in unserem Archiv Hunderte von Sitzungsprotokollen, welche ein Durchforsten und historisches Aufbereiten verdient hätten, was aber aus Zeitgründen vom Autor nicht zu bewerkstelligen war. Es liegt also ein spannendes historisches Forschungsgebiet brach, welches einer zukünftigen Bearbeitung harrt. Nebst dem Abhandeln des geschichtlichen Ablaufes war der Autor auch bestrebt, den historisch bedingten Ursprung verschiedenster Aktivitäten der NGB zu beleuchten und den Aktualitätsbezug herzustellen.
