Pilot-scale biogas desulfurization through anoxic biofiltration.

In this study, the performance of a pilot-scale biotrickling filter (BTF) for anoxic hydrogen sulfide (HS) removal from real biogas was evaluated over 226 days. The BTF, inoculated with activated sludge from a nearby wastewater treatment plant, operated in an industrial environment with raw biogas from an anaerobic digester fed with municipal solid waste. The operating strategy was based on controlling nitrate consumption by sulfur-oxidizing nitrate-reducing (SO-NR) bacteria.

Multivariate variable selection in N-of-1 observational studies via additive Bayesian networks.

An N-of-1 observational design characterizes associations among several variables over time in a single individual. Traditional statistical models recommended for experimental N-of-1 trials may not adequately model these observational relationships. We propose an additive Bayesian network using a generalized linear mixed-effects model for the local mean as a novel method for modeling each of these relationships in a data-driven manner.

Feasibility and Acute Toxicity of Hypo-Fractionated Radiotherapy on 0.35T MR-LINAC: The First Prospective Study in Spain.

This observational, descriptive, longitudinal, and prospective basket-type study (Registry #5289) prospectively evaluated the feasibility and acute toxicity of hypo-fractionated radiotherapy on the first 0.35T MR-LINAC in Spain. A total of 37 patients were included between August and December 2023, primarily with prostate tumors (59.

Growth, survival, digestive activity and respiratory metabolism of Octopus maya juveniles fed with prepared diets.

The effects of two prepared feeds were tested on growth, survival, enzymatic activity, nutritive reserves in the digestive gland and oxygen consumption of Octopus maya juveniles. For the first time, a semihumid paste (HD, control) and a dry diet, in pelleted form (PD, experimental) with the same formulation were used for this species. The experiment lasted for 42 days.
