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. 315]

O Deputado Jorge Hage (PMDB-BA), autor da emenda que concede quatro (4) anos de mandato para o Presidente José Sarney , acredita que o Plenário irá manter o resultado. A Comissão de Sistematização aprova mandato de quatro (4) anos para Presidente. Para o Deputado Francisco Benjamim (PFL-BA), o presidencialismo é o sistema de governo adequado. O Deputado Francisco Sales (PMDB-RO) acredita no parlamentarismo e no mandato de cinco (5) anos. Já o Deputado Roberto Balestra (PDC-GO) é contra mandato de cinco (5) anos. O Deputado José Lourenço (PFL-BA) reclama do voto de dois constituintes do PFL e tem esperança em reverter o resultado da votação. A Deputada Sandra Cavalcanti (PFL-RJ) decidiu seu voto depois do posicionamento do Senador Mário Covas (PMDB-SP). Covas concorda com quato (4) anos para o parlamentarismo, pois assim é provável que o Presidente seja comprometido com o sistema de governo. Segundo Deputado Ibsen Pinheiro (PMDB-RS) tudo direciona para um acordo entre presidencialistas e parlamentaristas, lideranças nacionais e Constituintes. O Deputado Carlos Sant'anna (PMDB-BA) acredita que com a eleição de José Sarney para Presidente não haverá mais condições de ter parlamentarismo. A Comissão examina artigo das disposições transitórias que trata da anistia. Rejeitada a emenda do Deputado Jamil Haddad (PSB-RJ) que propunha o pagamento de atrasados a todos os anistiados. A emenda do Deputado Brandão Monteiro (PDT-RJ) que propunha estender os benefícios da anistia à Marinha e Aeronáutica também não foi aprovada.

公路景观生态环境风险评价体系的建立和应用:以315国道新疆依吞布拉克—且末段为例

应用景观生态学思想,依据层次分析模式建立了公路生态环境风险评价体系,在专家思想库的基础之上,为突出各评价指标的空间属性,规定其权重值由评价指标影响空间范围的大小来确定.其中环境因子的影响范围,即所占面积,利用GIS对相关图件解读获得,灾害因子影响路段的长度则在施工设计和路线勘测阶段实测而得.使用该评价体系对31 5国道新疆依吞布拉克且末段的生态环境风险性进行评价,结果表明,该路域生态环境风险指数ERA介于1 . 5 5～3 . 2 3之间.由于ERA包含的生态环境脆弱性指数∑xiwi和灾害系数∑yiwj存在空间异质性,故据其最终对路域内的8个景观生态单元,用4个风险级别进行了评价,较真实地反映了该路段生态环境风险特征.

Influence of the pseudopotential on the properties of liquid rubidium at 315 K

The influence of the pseudopotential on both the structure and the self-diffusion of liquid rubidium at the melting point has been investigated by means of molecular-dynamics calculations. The model potential considered has been computed from the pseudopotential of Ashcroft, the dielectric function of Geldart and Vosko, and a Born-Mayer term. Four different values for the core radius which enters as input in the pseudopotential have been considered. In this way we have been able to observe and interpret the effect of this contribution on the properties of the liquid.

Nos últimos 3 dias, foram registradas 315 mil menções sobre falta d'água na internet

Monitoramento de redes sociais realizado pela Diretoria de Análise de Políticas Públicas da FGV nos últimos 3 dias registrou 315 mil menções relacionadas à crise hídrica em todo o Brasil. São Paulo foi a cidade com o maior volume de comentários, concentrando 16% do total, mais do que o dobro do Rio de Janeiro, a segunda cidade no ranking, com 7%. Os termos mais mencionados foram "água", com 46% do total, e "seca" com 32%. Outras palavras mencionadas foram "falta", "cantareira" e "racionamento".
