Surface layers (S-layers) are resilient two-dimensional protein lattices that encapsulate many bacteria and most archaea. In archaea, S-layers usually form the only structural component of cell wall thus act as final frontier between its environment. Therefore, crucial for supporting microbial life. Notwithstanding their importance, little is known about archaeal at atomic level. Here, we combined single-particle cryo electron microscopy, tomography, Alphafold2 predictions to generate an...

Summary A step drawdown test is a pumping in which the well observed while discharge rate from increased steps. The methods of analysis and criteria for planning tests are discussed evaluated order to produce an optimum programme comprehensive analysis. Step can be used determine aquifer transmissivity loss component pumped well. storage coefficient also estimated.

Abstract In an extensive study of pesticides in a Chalk catchment, twenty were selected for study; and this paper reports the findings eighteen‐month programme river rainwater sampling. The results periodic samples intensive monitoring over duration flood event are described. Both rain water within catchment found to contain significant numbers at varying concentrations. describes values temporal variations which discovered. Higher concentrations greater appeared be brought down by floods...

As part of a survey pesticides in the UK Major Aquifers, which WRc are undertaking on behalf National Rivers Authority, site at Assarts Farm near Mansfield Sherwood Sandstone aquifer has been selected for study pesticide movement unsaturated zone sandstone aquifer. A difficulty studying is need to obtain large volumes water analysis. WRc, co-operation with Soil Survey and Land Research Centre (SSLRC) tackled this problem by using modification SSLRC standard soil moisture suction sampler. The...
