Summary: Microbial pollution of aquifers is a global water quality problem that poses significant risks to public health. This study utilized flow cytometric analysis and fecal indicator bacteria to assess the potential of providing faster and more descriptive information on microbial pollution in karst aquifers. The study also evaluated the use of turbidity as a proxy indicator for fecal groundwater contamination. The findings suggest that flow cytometry can provide additional insights into fecal pollution sources and its fate and transport in karst catchments.

Summary: A soft sensor model based on multivariate time series analysis and convolutional neural network (MVTS-CNN) is proposed for online monitoring of free calcium oxide content in cement clinker production. By analyzing coupling relationship, time-varying delay, and extracting multivariate time series features, the MVTS-CNN model shows higher accuracy, better generalization ability, and superior robustness compared to traditional CNN, support vector machines (SVM), and long-short term memory networks (LSTM).

Summary: Leishmania braziliensis DNA was detected in the nasal mucosa of 30% of CL patients, and its presence was associated with reduced IL-12 levels, increased IL-6 levels, and a higher number of affected body segments. Early dissemination to the nasal mucosa was observed at a higher rate than previously described. Enhanced Th1 profile characterized by higher IL-12 levels may be important for preventing dissemination of L. braziliensis to the mucosa.

Summary: Contamination detection in drinking water is crucial for water utilities. Current online water quality sensors have limitations, so we used flow-imaging particle counters and conventional sensors to assess their responses. The flow-imaging particle counter detected all contaminants, with the oxidation-reduction potential sensor performing the best. Particles smaller than 1 mu m were important for detecting contaminants, but had lower response compared to larger particles due to fluctuations. Monitoring particles larger than 1 mu m or specific particle classes can improve contamination detection.

Summary: Spatial and short-term temporal changes in water quality in a drinking water distribution system were investigated, showing the combined effect of water age and fluctuating hydraulic conditions on microbiology and the impact of flow velocity on particle counts and turbidity. Hydraulic conditions had no detectable impact on suspended microbial cell concentration, but a weak correlation between flow velocity and ATP concentrations suggests incidental resuspension of particle-bound bacteria. The highly dynamic hydraulic conditions emphasize the value of online monitoring tools for describing short-term dynamics in drinking water distribution systems.

Summary: The study in the Rhine Valley and Tabular Jura east of Basel, Switzerland revealed that groundwater circulation was influenced by geological settings, with increased groundwater recharge leading to significant inflow into the Upper Muschelkalk karst aquifer. This results in fluctuations in groundwater flow and saturation regions within the karst aquifer.

Summary: Managed Aquifer Recharge (MAR) and Surface Water Recharge (MSWR) are effective strategies for climate change adaptation and have potential for thermal energy exploitation. However, adaptable implementation strategies of MAR and MSWR with concomitant exploitation of thermal energy potential have yet to be developed. This study presents strategies for the exploitation of hydrologic and energetic potentials of MAR and MSWR, taking into account hydrogeological conditions, legal aspects, and climate scenarios.

Summary: Decentralized greywater treatment and reuse systems exhibit high variability in flow, leading to short-term fluctuations in effluent water quality that can be monitored and controlled with automated tools. Biofilm detachment in biological activated carbon filters can cause temporary increases in turbidity and cell concentrations in effluent, but this does not lead to an increase in opportunistic pathogens. Turbidity measurements are sensitive to changes in effluent quality caused by intermittent flow.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
