Degradation of Norfloxacin in saline water by synergistic effect of anode and cathode in a novel photo-electrochemical system

The removal and degradation of refractory antibiotics in saline water by electrochemical and photo-electrochemical catalysis has emerged as a worldwide research hotspot. Aiming to improve degradation performance, most of the concerned studies focus on new sophisticated materials and modification methods on the single working electrode (anode or cathode). But the synergistic effects between anode a

Experimental and numerical assessment of structural behaviour of glass balustrade subjected to soft body impact

Glass is a commonly used material in modern architecture not only for building enclosures, but also for glazed barriers preventing building occupants from falling out of balconies and different levels inside buildings. The main purpose of the balustrades is to transfer the imposed loads to the main structure of the building. That includes static loads related to the crowd pressure (horizontal line

Public transport regimes and mobility as a service : Governance approaches in Amsterdam, Birmingham, and Helsinki

This paper examines governance responses to Mobility as a Service (MaaS). The analysis focuses on the interactions between public transport systems and MaaS developments in Amsterdam, Birmingham, and Helsinki. Case comparison is informed by the multilevel perspective on socio-technical transitions and literature on meta-governance of networks. Drawing on these frameworks and empirical findings, th

Traffic-Related Air Pollution as a Risk Factor for Dementia : No Clear Modifying Effects of APOEɛ4 in the Betula Cohort

It is widely known that the apolipoprotein E (APOE) ɛ4 allele imposes a higher risk for Alzheimer's disease (AD). Recent evidence suggests that exposure to air pollution is also a risk factor for AD, and results from a few studies indicate that the effect of air pollution on cognitive function and dementia is stronger in APOEɛ4 carriers than in non-carriers. Air pollution and interaction with APOE

Marine protected areas modulate habitat suitability of the invasive round goby (Neogobius melanostomus) in the Baltic Sea

Biological invasions are one of the leading causes of biodiversity loss worldwide. Given that eradication of invasive species is not usually a practical option, conservationists may attempt to limit their impacts through the designation and management of protected areas. Here, we investigate the effect of marine protected areas on the habitat suitability of an invasive species, the round goby (Neo

ETS and plastid sequence data indicate a spontaneous origin of Scandinavian betony, Betonica officinalis L.

Background and aims: Betony (Betonica officinalis L.) is one of the rarest and mostspectacular plants in the Scandinavian flora. A long-term question has been whether it is spontaneous or introduced, or whether it comprises both spontaneous and introduced populations. This study aimed to answer this question by analyzing sequence data from the nuclear external transcribed spacer (ETS) region and t

Search for a right-handed gauge boson decaying into a high-momentum heavy neutrino and a charged lepton in pp collisions with the ATLAS detector at s=13 TeV

A search for a right-handed gauge boson WR, decaying into a boosted right-handed heavy neutrino NR, in the framework of Left-Right Symmetric Models is presented. It is based on data from proton–proton collisions with a centre-of-mass energy of 13 TeV collected by the ATLAS detector at the Large Hadron Collider during the years 2015, 2016 and 2017, corresponding to an integrated luminosity of 80 fb

Statistical inference with deep latent variable models

Finding a suitable way to represent information in a dataset is one of the fundamental problems in Artificial Inelegance. With limited labeled information, unsupervised learning algorithms help to discover useful representations. One of the applications of such models is imputation, where missing values are estimated by learning the underlying correlations in a dataset.

Evidence for the production of three massive vector bosons with the ATLAS detector

A search for the production of three massive vector bosons in proton–proton collisions is performed using data at s=13 TeV recorded with the ATLAS detector at the Large Hadron Collider in the years 2015–2017, corresponding to an integrated luminosity of 79.8 fb−1. Events with two same-sign leptons ℓ (electrons or muons) and at least two reconstructed jets are selected to search for WWW→ℓνℓνqq. Eve

Not just fuel : energy stores are correlated with immune function and oxidative damage in a long-distance migrant.

In many animals, catabolic and anabolic periods are temporally separated. Migratory birds alternate energy expenditure during flight with energy accumulation during stopover. The size of the energy stores at stopover affects the decision to resume migration and thus the temporal organization of migration. We now provide data suggesting that it is not only the size of the energy stores per se that

Intraductal papillary mucinous carcinoma versus pancreatic ductal adenocarcinoma : A systematic review and meta-analysis

Background: Previous studies have indicated that there may be a difference in tumor biology between intraductal papillary mucinous carcinoma (IPMC) and pancreatic ductal adenocarcinoma (PDAC). However, the data are still controversial. The aim of this systematic review and meta-analysis was to summarize and compare the outcome of IPMC and PDAC after surgical resection. Methods: Studies comparing I

The microbial community size, structure, and process rates along natural gradients of soil salinity

Over 840 M ha of arable land is affected by salinization, and the area is predicted to increase due to global change. Assessments of the status of the microbial community in saline soils have frequently been based on microbial biomass estimates, which might not accurately reflect microbial process rates in soil. Moreover, assessments of how the relative importance of major decomposer groups bacter
