Integrating Biological Early Warning Systems with High-Resolution Online Chemical Monitoring in Wastewater Treatment Plants.

Detection of micropollutants (MPs) in wastewater effluents using traditional toxicity tests or chemical analysis with discrete samples is challenging due to concentration dynamics. This study evaluates a continuous monitoring approach for detecting MPs in wastewater effluents using a combination of biological early warning systems (BEWS). Three BEWS with , , and were operated in parallel in a full-scale municipal wastewater treatment plant.

Multiple slot modules for high field magnetic resonance imaging array coils.

Purpose: Mitigating coupling effects between coil elements represents a continuing challenge. Here, we present a 16-bowtie slot volume coil arranged in eight independent dual-slot modules without the use of any decoupling circuits.

Methods: Two electrically short "bowtie" slot antennas were used to form a "module.

Consolidation of Additive Manufactured Continuous Carbon Fiber Reinforced Polyamide 12 Composites and the Development of Process-Related Numerical Simulation Methods.

Additive manufacturing of high-performance polymers-such as PA12, PPS, PEEK, and PEKK-combined with industrial-grade carbon fibers with a high fiber volume ratio of up to 60% allows a weight reduction of over 40% compared to classic metal construction. Typically, these 3D-printed composites have a porosity of 10-30% depending on the material and the printing process parameters, which significantly reduces the quality of the part. Therefore, the additive manufacturing of load-bearing structural applications requires a proper consolidation after the printing process-the so-called 'additive fusion technology'-allowing close to zero void content in the consolidated part.

Assessing the Feasibility of Dynamic P Spectroscopy for Metabolic Studies With a 1.0T Extremity Scanner.

Objective: The feasibility of conducting in vivo non-localized P Magnetic Resonance Spectroscopy (MRS) with a 1.0T extremity scanner and the potential to increase accessibility of this important diagnostic tool for low cost applications is revisited.

Methods: This work presents a custom transmit-only quadrature birdcage, four-element receive coil array, and spectrometer interfaced to a commercial ONI 1.

High Prevalence of Supplement Intake with a Concomitant Low Information Quality among Swiss Fitness Center Users.

Background: The aim of this study was to screen the prevalence of supplement use in Swiss fitness center users and what information sources they consulted.

Methods: Customers of 10 fitness centers were screened with a quantitative questionnaire.

Results: Eighty two percent of the 417 fitness center users consumed at least one supplement per week.
