description: Bei der Herstellung von löslichem Kaffee fallen große Mengen Prozesswasser an, das schwer biologisch abbaubare Stoffe enthält. Dieses Wasser wird als Abwasser in das öffentliche Abwassersystem eingeleitet und durch die kommunale Kläranlage behandelt. Allerdings können die schwer abbaubaren Stoffe auf Grund ihrer Zusammensetzung dort nicht vollständig abgebaut werden. Mit dem Vorhaben ist eine Prozesswassernachbehandlungsanlage für hochkonzentrierte Prozesswässer aus der Produktion errichtet worden. Das vormals unbehandelte Wasser wird darin in mehreren Prozessschritten vorkonditioniert und über eine speziell konfigurierte Membranbiologie geführt. Eine hohe Belebtschlammkonzentration wird mit einem hohen Befüllstand der Behälter kombiniert, in welche Luftsauerstoff effizient und mit geringem Energiebedarf eingetragen werden kann. Der Belebtschlamm wird einem Membranfiltrationsprozess zugeführt. Das gereinigte Prozesswasser wird anschließend in das Abwassersystem eingeleitet. Mit diesem Verfahren konnte die CSB-Konzentration der Prozesswässer von über 10.000 mg/l vor dem Vorhaben auf ca. 2.500 mg/l gesenkt werden. Zielsetzung waren 2.000 mg/l. Im Vergleich zu einem konventionellen Verfahren wird das Abfallaufkommen verringert und Energie eingespart. Damit einher gehen CO2-Minderungen von rund 10.500 Tonnen jährlich. Das innovative Verfahren ist übertragbar auf andere Unternehmen der Kaffeebranche. Quelle: Forschungsbericht
description: During the production of instant coffee, large quantities of process water containing persistent substances accumulate. This water is discharged into the public sewage system as waste water and treated by the municipal sewage treatment plant. However, due to their composition, the persistent substances cannot be completely broken down there. The project aims to build a process water treatment plant for highly concentrated process water from production. The previously untreated process water will be pre-conditioned in several process steps and led through specially configured membrane biology. A high concentration of activated sludge is combined with a high filling level of tanks, into which atmospheric oxygen is introduced. This activated sludge-water mixture is fed into a membrane filtration process. The purified process water is then discharged into the wastewater system. With this method the COD content of the process water decreased from over 10,000 mg/l prior to the project to around 2,500 mg/l. The goal was 2,000 mg/l. Compared to a conventional process, the amount of waste is reduced and energy is saved. This leads to CO2 reductions of around 10,500 tons per year. The innovative process is transferable to other companies in the coffee industry. Quelle: Forschungsbericht

description: Traditionally, university supervisors have provided coaching to special education preservice teachers after direct observations of sessions within the classroom. As a result of the COVID-19 pandemic, many public school districts in the United States enforced visitor restriction policies that made face-to-face observations difficult or impossible. When faced with this challenge, university supervisors were forced to consider alternative ways to provide feedback. Many questioned whether virtual coaching was as effective as in-person coaching in increasing teacher behaviors. Presently, there are limited studies that suggest one delivery method is more effective or efficient than the other. This study used a Repeated Acquisition Design to compare the effectiveness and social validity of in-person and virtual coaching models in increasing the use of HLPs in special education student teachers.

description: Introduction: Postgraduate medical trainees frequently work ≥ 24- hour shifts causing fatigue and adverse consequences such as motor vehicle incidents (MVIs). We aim to determine the incidence of MVIs during the commutes of trainees in British Columbia (BC) in the preceding year. Methods: We completed a retrospective, cross-sectional survey of trainees regarding work hours, shifts, and MVIs in the previous year. MVIs included falling asleep while driving, sudden braking or swerving to avoid a collision, unintentionally running a red light or stop sign, or collisions. Results: Of 273 respondents, over half (54.6%) reported ≥1 MVI, one in 14 were in a collision (7.0%), and two thirds (66.3%) reported that the safety of their commute had been impacted by fatigue in the past year. After adjustment for road exposure and shift-related factors, every ten km increase in commute length was associated with an increased risk of MVI (aOR=1.54;95%CI:1.15- 2.12). Reported attentional failures, such as unintentionally running a red light and/or stop sign, increased for every ten hours on-call (aOR=1.44;95%CI:1.03-2.04) and for every additional pastmidnight shift worked (aOR=1.13;95%CI:1.01-1.26). Discussion: Trainees with longer and more frequent commutes had an increased risk of MVIs. Trainees who worked more hours on-call and more past-midnight shifts reported significantly more attentional failures while commuting. This study helps us understand factors affecting trainee commuter safety and supports calls for the provision of safe alternatives to commuting for postgraduate trainees.

description: Objectives: Bacterial infections are a major cause of UK paediatric hospitalisations, yet longitudinal data on causative organisms or antimicrobial resistance are scarce. This retrospective analysis describes trends in blood and cerebrospinal fluid (CSF) cultures and resistance patterns in children under three years old from a large UK centre. Methods: All culture results, and resistance data for Gram-negative rods (GNR) in blood cultures, collected between January 2005 and December 2018 were extracted from Oxford University Hospitals NHS Foundation Trust microbiology database. Results: Of 49,298 samples, 6.7% of blood and 3.1% of CSF cultures were positive for bacterial growth; 2.3% and 1.1% respectively grew pathogens. Number of cultures taken increased over time; the proportion growing pathogens declined. Resistance of GNR to first-line antimicrobials was 9.3% to gentamicin (neonatal units), and 17.1% and 25.8% to ceftriaxone (paediatric ED and wards respectively). Resistance to any two of ceftriaxone, ciprofloxacin, gentamicin, or meropenem was ≤6% in both areas. Conclusions: The proportion of positive cultures declined over time. Resistance of GNR to empirical antimicrobials were observed, but resistance to a second agent were lower. Our study informs clinician decisions on when, and to which antimicrobials, to escalate if a child is not improving on empirical therapy.

description: Functional analysis (FA) is a tool practitioners can utilize to identify the function of challenging behavior. An interview informed contingency analysis (IISCA) is a variation of a FA. In an effort to improve patient care within a university-based clinic, a within-session analysis of the first test condition of an IISCA was conducted to determine if a shorter assessment yield results similar to the full IISCA. An alternating treatments design was used to evaluate differentiated rates of challenging behavior across conditions for eleven client cases at the university-based clinic. A single test session was enough to determine the function of challenging behavior and the first test condition produced similar results to the whole IISCA for some of the cases reviewed.

description: Bayesian optimal experimental design (OED) seeks experiments that maximize the expected information gain (EIG) in model parameters. Directly estimating the EIG using nested Monte Carlo is computationally expensive and requires an explicit likelihood. Variational OED (vOED), in contrast, estimates a lower bound of the EIG without likelihood evaluations by approximating the posterior distributions with variational forms, and then tightens the bound by optimizing its variational parameters. We introduce the use of normalizing flows (NFs) for representing variational distributions in vOED; we call this approach vOED-NFs. Specifically, we adopt NFs with a conditional invertible neural network architecture built from compositions of coupling layers, and enhanced with a summary network for data dimension reduction. We present Monte Carlo estimators to the lower bound along with gradient expressions to enable a gradient-based simultaneous optimization of the variational parameters and the design variables. The vOED-NFs algorithm is then validated in two benchmark problems, and demonstrated on a partial differential equation-governed application of cathodic electrophoretic deposition and an implicit likelihood case with stochastic modeling of aphid population. The findings suggest that a composition of 4--5 coupling layers is able to achieve lower EIG estimation bias, under a fixed budget of forward model runs, compared to previous approaches. The resulting NFs produce approximate posteriors that agree well with the true posteriors, able to capture non-Gaussian and multi-modal features effectively.

description: Cyclic volatile methylsiloxanes (cVMS) are widely applied chemicals used as intermediates in the production of silicon polymers or as ingredients in personal care products. cVMS are under scrutiny due to their environmental properties and their potential for long-range atmospheric transport, persistence and food web magnification. In 2018, the cVMS octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5) and dodecamethylcyclohexasiloxane (D6) were identified as Substances of Very High Concern (SVHC) under the European REACH regulation. To obtain current data on the presence of cVMS in German waters, the spatial and temporal occurrence of D4, D5 and D6 in fillets of bream from major rivers archived in the German Environmental Specimen Bank (ESB) was analyzed with a GC-ICP-MS/MS coupling method. The spatial comparison of 17 sites for the year 2017 revealed that highest cVMS burdens occurred in samples from the Saar river (near to the French/German border). cVMS levels in fish from a lake in northern Germany did not exceed the limits of detection. For selected sites, time series covering the period from 1995 to 2017 were investigated. In most years D5 concentrations in fish were clearly higher than the observed D4 and D6 concentrations. Overall maximum D4 and D5 concentrations (about 320 and 7600 ng gâ Ì1 wet weight, respectively) were found at one Saar site in 2009. In three of five analyzed time series D5 concentrations peaked 2007â€Ì2011. In recent years, cVMS levels in fish decreased at almost all sites. To allow an assessment of the relevance of the detected cVMS fish concentrations these were compared to environmental quality standards (EQS) for D4 and D5 which were recently enacted in the context of the Swedish implementation of the European Water Framework Directive (WFD). The D5 EQS in fish was exceeded at four sites in several years in the investigated period and in the Saar even till 2017.

description: In the easy-plane phase, a ferromagnetic spin-1 Bose-Einstein condensate is magnetized in a plane transverse to the applied Zeeman field. This phase supports polar-core spin vortices (PCVs), which consist of phase windings of transverse magnetization. Here we show that spin-changing collisions cause a PCV to accelerate down density gradients in an inhomogeneous condensate. The dynamics is well-described by a simplified model adapted from scalar systems, which predicts the dependence of the dynamics on trap tightness and quadratic Zeeman energy. In a harmonic trap, a PCV accelerates radially to the condensate boundary, in stark contrast to the azimuthal motion of vortices in a scalar condensate. In a trap that has a local potential maximum at the centre, the PCV exhibits oscillations around the trap centre, which persist for a remarkably long time. The oscillations coincide with the emission and reabsorption of axial spin waves, which reflect off the condensate boundary.

description: Under the Australian Constitution, matters relating to communications are a national responsibility. However, until recently, there had been a broad consensus across the political parties about most communications policies, with the major exception of the privatisation of the former incumbent, Telstra. This consensus no longer holds. One of the issues raised by all sides in the recent election period was 'broadband', and there is no doubt that, now the election results are clear, Australia may actually be on the way to developing a broadband policy. This article reviews the background to the recent policy debate, and provides some comment on the issues that have been raised in the Election Campaign.

description: The structure of sodium saccharinate 1.875-hydrate is presented in three- and (3+1)-dimensional space. The present model is more accurate than previously published superstructures, due to an excellent data set collected up to a high resolution of 0.89Å\sp -}1}. The present study confirms the unusual complexity of the structure comprising a very large primitive unit cell with \it Z\prime = 16. A much smaller degree of correlated disorder of parts of the unit cell is found than is present in the previously published models. As a result of pseudo-symmetry, the structure can be described in a higher-dimensional space. The X-ray diffraction data clearly indicate a (3+1)-dimensional periodic structure with stronger main reflections and weaker superstructure reflections. Furthermore, the structure is established as being commensurate. The structure description in superspace results in a four times smaller unit cell with an additional base centring of the lattice, resulting in an eightfold substructure (\it Z\prime = 2) of the 3D superstructure. Therefore, such a superspace approach is desirable to work out this high-\it Z\prime structure. The displacement and occupational modulation of the saccharinate anions have been studied, as well as their conformational variation along the fourth dimension.
Technical note : Effects of iron(II) on fluorescence properties of dissolved organic matter at circumneutral pH

description: Modern fluorescence spectroscopy methods, including excitation–emission matrix (EEM) spectra parsed using parallel factor analysis (PARAFAC) statistical approaches, are widely used to characterize dissolved organic matter (DOM) pools. The effect of soluble reduced iron, Fe(II), on EEM spectra can be significant but is difficult to quantitatively assign. In this study, we examine the effects of Fe(II) on the EEM spectra of groundwater samples from an anaerobic deltaic aquifer containing up to 300 mg L-¹ Fe(II), located a few kilometres from the ocean and adjacent to the Fraser River in Richmond, British Columbia, Canada. We added varying quantities of Fe(II) into groundwater samples to evaluate Fe(II)–DOM interactions. Both the overall fluorescence intensity and the intensity of the primary peak, a humic-like substance at excitation and emission wavelengths of 239 and 441–450 nm (peak A), respectively, decreased by approximately 60 % as Fe(II) concentration increased from 1 to 306 mg L-¹ . Furthermore, the quenching effect was nonlinear and proportionally stronger at Fe(II) concentrations below 100 mg L−1 . This nonlinear relationship suggests a static quenching mechanism. In addition, DOM fluorescence indices are substantially influenced by the Fe(II) concentration. With increasing Fe(II), the fluorescence index (FI) shifts to higher values, the humidification index (HIX) shifts to lower values, and the freshness index (FrI) shifts to higher values. Nevertheless, the 13-component PARAFAC model showed that the component distribution was relatively insensitive to Fe(II) concentration; thus, PARAFAC may be a reliable method for obtaining information about the DOM composition and its redox status in Fe(II)-rich waters. By characterizing the impacts of up to 300 mg L-¹ Fe(II) on EEMs using groundwater from an aquifer which contains similar Fe(II) concentrations, we advance previous work which characterized impacts of lower Fe(II) concentrations (less than 2 mg L-¹) on EEMs.
Impact of methodological assumptions and covariates on the cutoff estimation in ROC analysis

description: The Receiver Operating Characteristic (ROC) curve stands as a cornerstone in assessing the efficacy of biomarkers for disease diagnosis. Beyond merely evaluating performance, it provides with an optimal cutoff for biomarker values, crucial for disease categorization. While diverse methodologies exist for threshold estimation, less attention has been paid to integrating covariate impact into this process. Covariates can strongly impact diagnostic summaries, leading to variations across different covariate levels. Therefore, a tailored covariate-based framework is imperative for outlining covariate-specific optimal cutoffs. Moreover, recent investigations into cutoff estimators have overlooked the influence of ROC curve estimation methodologies. This study endeavors to bridge this gap by addressing the research void. Extensive simulation studies are conducted to scrutinize the performance of ROC curve estimation models in estimating different cutoffs in varying scenarios, encompassing diverse data-generating mechanisms and covariate effects. Additionally, leveraging the Alzheimer's Disease Neuroimaging Initiative (ADNI) dataset, the research assesses the performance of different biomarkers in diagnosing Alzheimer's disease and determines the suitable optimal cutoffs.

description: PFAS contamination of surface waters in central Europe was investigated in a spatial monitoring using suspended particulate matter and sediment samples. The samples were collected in 2021 at 171 sampling sites in Germany and at five sites in Dutch waters. All samples were analyzed for 41 different PFAS by target analysis to establish a baseline for these compounds. In addition, a sum parameter approach (direct Total Oxidizable Precursor (dTOP) assay) was used to investigate the PFAS load in the samples more comprehensively. PFAS pollution varied widely between water bodies. Target analysis detected (Sigma)PFAS concentrations between <0.5 and 53.1 (micro)g kg-1 dry weight (dw), while levels of <1.0-337(micro)g kg-1 dw were determined by dTOP assay. Associations were observed for (Sigma)PFSAdTOP and the percentage of urban area in the vicinity of the sampling sites and, less strongly, for distances to industrial sites (i.e. galvanic/paper) and airports. PFAS hotspots were identified by setting the 90th percentile of the data sets for (Sigma)PFAStarget or (Sigma)PFASdTOP as a threshold. Of the 17 hotspots identified by target analysis or dTOP assay, respectively, there were only six overlaps. Thus, 11 highly contaminated sites could not be identified by classical target analysis. The results demonstrate that target analysis captures only a fraction of the actual PFAS load, while unknown precursors remain undetected. Consequently, if only the results of target analysis are considered in assessments, there is a risk that sites heavily polluted with precursors will not be identified delaying mitigation actions and risking prolonged negative impacts on human health and ecosystems. Moreover, effective PFAS management requires establishing a baseline for PFAS using target and sum parameters such as the dTOP assay, and then monitoring this baseline on a regular basis to support emission control and to inform risk management of its effectiveness. © 2023 The Authors.

description: Background The well-being of people who use drugs (PWUD) continues to be threatened by substances of unknown type or quantity in the unregulated street drug supply. Current efforts to monitor the drug supply are limited in population reach and comparability. This restricts capacity to identify and develop measures that safeguard the health of PWUD. This study describes the development of a low-barrier system for monitoring the contents of drugs in the unregulated street supply. Early results for pilot sites are presented and compared across regions. Methods The drug content monitoring system integrates a low-barrier survey and broad spectrum urine toxicology screening to compare substances expected to be consumed and those actually in the drug supply. The system prototype was developed by harm reduction pilot projects in British Columbia (BC) and Montreal with participation of PWUD. Data were collected from harm reduction supply distribution site clients in BC, Edmonton and Montreal between May 2018–March 2019. Survey and urine toxicology data were linked via anonymous codes and analyzed descriptively by region for trends in self-reported and detected use. Results The sample consisted of 878 participants from 40 sites across 3 regions. Reported use of substances, their detection, and concordance between the two varied across regions. Methamphetamine use was reported and detected most frequently in BC (reported: 62.8%; detected: 72.2%) and Edmonton (58.3%; 68.8%). In Montreal, high concordance was also observed between reported (74.5%) and detected (86.5%) cocaine/crack use. Among those with fentanyl detected, the percentage of participants who used fentanyl unintentionally ranged from 36.1% in BC, 78.6% in Edmonton and 90.9% in Montreal. Conclusions This study is the first to describe a feasible, scalable monitoring system for the unregulated drug supply that can contrast expected and actual drug use and compare trends across regions. The system used principles of flexibility, capacity-building and community participation in its design. Results are well-suited to meet the needs of PWUD and inform the local harm reduction services they rely on. Further standardization of the survey tool and knowledge mobilization is needed to expand the system to new jurisdictions.

description: Da secoli, guerre, persecuzioni e, sempre più spesso, i disastri naturali spingono le persone a fuggire dal proprio paese e a migrare in cerca di rifugio e protezione, ma anche di condizioni di vita sicure. Nonostante ciò, prima della fine degli anni ‘90, l’Italia non rappresentava una delle principali mete migratorie, né per i migranti economici che per i rifugiati. È per questo che ancora oggi tanto i politici quanto l’opinione pubblica difficilmente definiscono l’Italia una nazione di immigrazione.

description: This article comments on FTTH, stating that it is generally-accepted to be the “end-point” in access network transformation, although there is less consensus on exactly when and what path this journey to FTTH should take. FTTH is a complicated interplay of business, regulatory and technology considerations and these are briefly discussed in the article.

description: To address the gaps in the literature examining eating disorders among males and gender minority youths, a prospective study was designed to assess gender differences in eating disorder symptom presentation and outcomes. Muscularity concerns may be particularly relevant for male youths with eating disorders, and were included in assessment of eating disorder symptom presentation. Methods: All cisgender male youths who presented for specialized eating disorder treatment at one of two sites were invited to participate, along with a group of matched cisgender females, and all youths who did not identify with the sex assigned to them at birth. Youths completed measures of eating disorder symptoms, including muscularity concerns, and other psychiatric symptoms at baseline and end of treatment. Results: A total of 27 males, 28 females and 6 trans youths took part in the study. At baseline, Kruskal–Wallis tests demonstrated that trans youths reported higher scores than cisgender male and female youths on measures of eating pathology (Eating disorder examination-questionnaire (EDE-Q) and the body fat subscale of the male body attitudes scale (MBAS)). These analyses demonstrated that there were no differences between cisgender male and female youths on eating disorder symptoms at baseline. However, repeated measures ANOVA demonstrated that males had greater decreases in eating pathology at discharge than did females, based on self-reported scores on the EDE-Q, MBAS, and Body Change Inventory. Conclusions: Gender differences in eating pathology appeared at baseline, with trans youths reporting higher levels of eating pathology than cisgender youths, though no differences between cisgender males and females emerged at baseline for eating disorder symptom presentation. Contrary to expectations, there were no gender differences in measures of muscularity concerns. Males demonstrated greater eating disorder symptom improvements than females, suggesting that male adolescents may have better treatment outcomes than females in some domains.

description: Der Beitrag stellt eine umfassende bibliometrische Untersuchung der Entwicklung der Open-Access-Verfügbarkeit wissenschaftlicher Zeitschriftenartikel in Deutschland für den Zeitraum 2010-18 vor. Die Studie gibt damit Einblick, wie sich das Open-Access-Publizieren aus institutioneller Sicht entwickelte, bevor deutschlandweite Open-Access-Rahmenverträge mit großen Wissenschaftsverlagen geschlossen wurden. Ein besonderes Augenmerk der Analyse lag auf der Frage, ob und inwiefern sich die Open-Access-Profile der Hochschulen und außeruniversitären Wissenschaftseinrichtungen in Deutschland voneinander unterscheiden. Auf Grundlage der qualitätsgesicherten Web of Science Datenbank des Kompetenzzentrum Bibliometrie wurden 900,000 Zeitschriftenartikel mit Autorinnen und Autoren deutscher Wissenschaftseinrichtungen identifiziert, die zwischen 2010-18 veröffentlicht wurden. Rund 44% waren zum Zeitpunkt unserer Erhebung im Open Access verfügbar. Jedoch unterscheiden sich die Publikationsprofile sowohl der einzelnen Einrichtungen als auch der Sektoren voneinander. Die Studie zeigt zudem, dass Open-Access-Publikationswege unterschiedlich ausgeprägt sind. Im Vortrag möchten wir besonders auf diese Varianzen eingehen und mögliche Erklärungen mit der Fachcommunity diskutieren.

description: A higher active travel speed has offsetting impacts on air pollution inhalation dose through higher breathing rate but shorter exposure duration. The net effect of speed choice on inhalation dose for pedestrians and bicyclists has not been established. This paper derives equations for pedestrian and bicycle steady-state minimum-dose speed (MDS). Parameter distributions from the literature are applied to a synthetic population of travelers to calculate individual MDS. Results strongly support the existence of a definable MDS, which is near observed travel speeds for urban pedestrians and bicyclists. For a wide range of travelers, the MDS is 2–6 km/h while walking and 12–20 km/h while bicycling, decreasing with road grade at a rate similar to observed speeds. On level ground, pedestrian and bicycle MDS corresponds to a moderate-intensity physical activity level (3–6 MET). Small deviations from the MDS have little effect, but large deviations (by more than 10 km/h for bicycling) can more than double inhalation dose over a fixed distance. It appears that pedestrians and bicyclists choose travel speeds that approximately minimize pollution inhalation dose, although pollution is unlikely a primary motivation.

description: Consumer, legal, and technological factors influence the design, performance, and emissions of light-duty vehicles (LDVs). This work examines how design choices made by manufacturers for the UK market result in emissions and performance of vehicles throughout the past decade (2001–2011). LDV fuel consumption, CO2 emissions, and performance are compared across different combinations of air and fuel delivery system using vehicle performance metrics of power density and time to accelerate from rest to 100 km/h (62 mph, tz-62). Increased adoption of direct injection and turbocharging technologies helped reduce spark ignition (SI, gasoline vehicles) and compression ignition (CI, diesel vehicles) fuel consumption by 22% and 19%, respectively, over the decade. These improvements were largely achieved by increasing compression ratios in SI vehicles (3.6%), turbocharging CI vehicles, and engine downsizing by 5.7–6.5% across all technologies. Simultaneously, vehicle performance improved, through increased engine power density resulting in greater acceleration. Across the decade, tz-62 fell 9.4% and engine power density increased 17% for SI vehicles. For CI vehicles, tz-62 fell 18% while engine power density rose 28%. Greater fuel consumption reductions could have been achieved if vehicle acceleration was maintained at 2001 levels, applying drive train improvements to improved fuel economy and reduced CO2 emissions. Fuel consumption and CO2 emissions declined at faster rates once the European emissions standards were introduced with SI CO2 emissions improving by 3.4 g/km/year for 2001–2007 to 7.8 g/km/year thereafter. Similarly, CI LDVs declined by 2.0 g/km/year for 2001–2007 and 6.1 g/km/year after.
