How efficiently does a metabolically enhanced system with denitrifying anaerobic methane oxidizing microorganisms remove antibiotics?

In this work, the novel N-damo (Nitrite dependent anaerobic methane oxidation) process was investigated at high biomass activities for its potential to remove simultaneously nitrite and methane, as well as selected antibiotics commonly found in sewage in trace amounts. For this purpose, two MBRs were operated at three high nitrite loading rates (NLRs), namely 76 ± 9.9, 161.

Cometabolic removal of organic micropollutants by enriched nitrite-dependent anaerobic methane oxidizing cultures.

The innovative and recently discovered n-damo process, based on anaerobic methane oxidation with nitrite, was developed in a membrane-based bioreactor and evaluated in terms of organic micropollutants (OMPs) removal. The main singularity of this study consisted in the evaluation of organic micropollutants (OMPs) removal in the biological reactor. A strategy consisting on progressively increasing the nitrogen loading rate in order to increase the specific denitrification activity was followed to check if the selected OMPs were co-metabolically biotransformed.

Reaching Consensus in Polarized Moral Debates.

The group polarization phenomenon is a widespread human bias with no apparent geographical or cultural boundaries [1]. Although the conditions that breed extremism have been extensively studied [2-5], comparably little research has examined how to depolarize attitudes in people who already embrace extreme beliefs. Previous studies have shown that deliberating groups may shift toward more moderate opinions [6], but why deliberation is sometimes effective although other times it fails at eliciting consensus remains largely unknown.

A massive experiment on choice blindness in political decisions: Confidence, confabulation, and unconscious detection of self-deception.

We implemented a Choice Blindness Paradigm containing political statements in Argentina to reveal the existence of categorical ranges of introspective reports, identified by confidence and agreement levels, separating easy from very hard to manipulate decisions. CBP was implemented in both live and web-based forms. Importantly, and contrary to what was observed in Sweden, we did not observe changes in voting intentions.

Arithmetic on Your Phone: A Large Scale Investigation of Simple Additions and Multiplications.

We present the results of a gamified mobile device arithmetic application which allowed us to collect vast amount of data in simple arithmetic operations. Our results confirm and replicate, on a large sample, six of the main principles derived in a long tradition of investigation: size effect, tie effect, size-tie interaction effect, five-effect, RTs and error rates correlation effect, and most common error effect. Our dataset allowed us to perform a robust analysis of order effects for each individual problem, for which there is controversy both in experimental findings and in the predictions of theoretical models.

Paratuberculosis in free-ranging fallow deer in Spain.

Paratuberculosis was diagnosed in a population of approximately 1,000 free-ranging fallow deer (Dama dama) sampled from 1997-98 in the Regional Hunting Reserve of El Sueve (Asturias, Spain). Five of eight animals observed with diarrhea were diagnosed as having paratuberculosis on the basis of gross lesions at postmortem examination and histopathology. In two deer, Mycobacterium avium subsp.
