Sediment OM is largely protected from aerobic mineralization under water saturated conditions but are vulnerable when exposed to oxygen during periods of drought. As climate change progresses, drought periods are likely to occur more frequently and may affect OM mineralization, and thus the release of greenhouse gases (GHGs) such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) from pond ecosystems. Therefore, we aimed to test how GHG emissions and concentrations in the sediment respond to drought by gradually decreasing water levels to below the sediment surface. To this end, undisturbed sediment cores from two small ponds with distinct watershed and water chemistry characteristics were incubated in mesocosms for 118 days at 20°C. Water levels were sequentially tested at 3 cm above the sediment surface (Phase I) and at the level of the sediment surface (Phase II). In Phase III, water levels were continuously lowered either by evaporation or by active drainage including evaporation. Mean CH4 fluxes of both ponds were high (21 and 87 mmol m-2 d-1), contributing 90 and 96% to the GHG budget over the three phases. The highest CH4 fluxes occurred in Phase II, while active drainage strongly reduced CH4 fluxes in Phase III. A multivariate analysis suggests that dissolved organic carbon and sulphate were important drivers of CH4 fluxes in Phase III. CO2 and N2O fluxes also responded to declining water levels, but their contribution to the GHG budget was rather small. Both gases were primarily produced in the upper sediment layer as indicated by highest concentrations at 5 cm sediment depth. Compaction of sediment cores by water level lowering increased bulk density and maintained high water contents. This side effect, retarding the drying of the sediment surface, was possibly relevant for the GHG net emission of the sediments in Phase II and III. Overall, GHG fluxes from the sediments exhibited high sensitivity to falling water levels. This study suggests that drying pond sediments have great potential to emit large amounts of GHGs to the atmosphere in the event of drought, representing hot spots of GHGs in the landscape.Research Data Open Access Design strategies for stack-based piezoelectric energy harvesters near bridge bearings(2025-06-24) Mattauch, Philipp; Schneider, Oliver; Fischerauer, GerhardFE data contains the Ansys Mechanical APDL input files (*.txt) and the recorded time series results for the different load cases and stiffnesses of the COMBIN14 element representing the piezoelectric Energy harvesting system (*.csv).

Here, we introduce the q-analogs of group divisible designs. It turns out that there are interesting connections to scattered subspaces, q-Steiner systems, packing designs and q^r-divisible projective sets. We give necessary conditions for the existence of q-analogs of group divisible designs, construct an infinite series of examples, and provide further existence results with the help of a computer search. One example is a (6,3,2,2)_2 group divisible design over GF(2) which is a packing design consisting of 180 blocks that such every 2-dimensional subspace in GF(2^6) is covered at most twice.Item Open Access Original data of the publication: Capacitive gas-phase detection in liquid nitrogen(University of Bayreuth, 2017-02-14) Kandlbinder, Christoph; Fischerauer, Alice; Mösch, Mario; Helling, Tobias; Fischerauer, Gerhard; Siegl, MartinThese data sets are raw simulated and measured data belonging to the article 'Capacitive gas-phase detection in liquid nitrogen' in the open-access peer-reviewed journal of Sensors and Sensor Systems (JSSS).
