description: A novel sensor operation concept for detecting ppb-level NO₂ concentrations at room temperature is introduced. Today’s research efforts are directed to make the sensors as fast as possible (low response and recovery times). Nevertheless, hourly mean values can hardly be precisely calculated, as the sensors are still too slow and show baseline drifts. Therefore, the integration error becomes too large. The suggested concept follows exactly the opposite path. The sensors should be made as slow as possible and operated as resistive gas dosimeters. The adsorption/desorption equilibrium should be completely shifted to the adsorption side during a sorption phase. The gas-sensitive material adsorbs each NO₂ molecule (dose) impinging and the sensor signal increases linearly with the NO₂ dose. The actual concentration value results from the time derivative, which makes the response very fast. When the NO₂ adsorption capacity of the sensor material is exhausted, it is regenerated with ultraviolet (UV) light and the baseline is reached again. Since the baseline is newly redefined after each regeneration step, no baseline drift occurs. Because each NO₂ molecule that reaches the sensor material contributes to the sensor signal, a high sensitivity results. The sensor behavior of ZnO known so far indicates that ZnO may be suitable to be applied as a room-temperature chemiresistive NO₂ dosimeter. Because UV enhances desorption of sorbed gas species from the ZnO surface, regeneration by UV light should be feasible. An experimental proof demonstrating that the sensor concept works at room temperature for ppb-level NO₂ concentrations and low doses is given.

description: Love is a moral value; it's also a great slogan. The problem, of course, is that like all slogans, it lacks nuance. Selfless love of the stranger is a moral value for sure, but is self-love a moral value? Love of the family, yes, but love of the familiar? How about love of other species, even at the expense of our own? The problem with nuance is that it bores people. The purpose of this symposium is to work against that boredom, so that we and the academic world in the largest sense may begin to renew ourselves as a voice worth listening to. If love is a moral value—and I think it is—then the success of this symposium will be in finding a way for this university to discuss moral values, by transcending the current paradigm of loveless objectivity that has gone so far in making our voices irrelevant to so many people.

description: Tetrafluoroethylene (TFE) and hexafluoropropylene (HFP) are the most common monomers for the synthesis of fluoropolymers at industrial scale. Currently, TFE is produced via multistep pyrolysis of chlorodifluoromethane (R22), resulting in a high energy demand and high amounts of waste acids, mainly HCl and HF. In this study, a new chlorine-free process for producing TFE and HFP in a microreactor is presented, starting from partially fluorinated alkanes obtained from electrochemical fluorination (ECF). In the microreactor, high conversion rates of CHF3, which is used as a surrogate of partly fluorinated ECF streams, and high yields of fluoromonomers could be achieved. The energy saving and the environmental impact are shown by a life cycle assessment (LCA). The LCA confirms that the developed process has economical as well as ecological benefits, and is thus an interesting option for future industrial production of fluoroalkenes.

description: An arsenic biosorbent comprising neem leaves (NL) and MnFe2O4 particles was developed and its removal potential was investigated. Physicochemical analysis of the NL/MnFe2O4 composite (MNL) was performed for the Brunauer, Emmett and Teller surface area, Fourier transform infrared spectra (FT-IR), and scanning electron microscopy–Energy-dispersive X-ray (EDX). The following parameters were optimized: pH, biosorbent dose, contact time, temperature, and initial arsenic concentration. The optimum pH values achieved for biosorption of As(III) and As(V) were 7.0 and 4.0, respectively, when the equilibrium time was 110 minutes for both. MNL was found to be efficient with 85.217% and 88.154% biosorption efficiency at a concentration of 50 mg/L of As(III) or As(V) solution, respectively. This was also proved by the FT-IR study of arsenic-loaded biosorbent. For establishing the best suitable correlation for the equilibrium curves exploiting the procedure of the nonlinear regression for curve fitting analysis, isotherm studies were conducted for As(III) and As(V) using 30 isotherm models. The pattern of biosorption fitted well with Brouers–Sotolongo isotherm model for As(III) and Langmuir–Freundlich as well as Sips isotherm models for As(V). Dubinin–Radushkevich (D-R) isotherm studies specified that ion exchange might play a significant role. The influence of various co-existing ions at different concentrations was examined. Desorption study was performed using various concentrations of NaOH solution.

description: Recently, radio frequency (RF) technology was introduced as a tool to determine the oxygen storage level of a three-way catalyst (TWC) for gasoline vehicles. Previous studies on the investigation of commercial catalysts mostly use only the resonant frequency to describe the correlation of oxygen storage level and RF signal. For the first time this study presents a comparison under defined laboratory conditions considering both, resonance frequency and also the quality factor as measurands. Furthermore, various advantages over the sole use of the resonant frequency in the technical application are discussed. Experiments with Ø4.66" catalysts and Ø1.66" catalyst cores with alternating (rich/lean) gas compositions showed that the relative change in signal amplitude due to a change in oxygen storage is about 100 times higher for the inverse quality factor compared to the resonant frequency. In addition, the quality factor reacts more sensitively to the onset of the oxygen-storage ability, and delivers precise information about the necessary temperature, which is not possible when evaluating the resonant frequency due to the low signal amplitude. As investigations on aged catalysts confirm, the quality factor also provides a new approach to determine operando the ageing state of a TWC.

description: Objectives Weekly monitoring of European all-cause excess mortality, the EuroMOMO network, observed high excess mortality during the influenza B/Yamagata dominated 2017/18 winter season, especially among elderly. We describe all-cause excess and influenza-attributable mortality during the season 2017/18 in Europe. Methods Based on weekly reporting of mortality from 24 European countries or sub-national regions, representing 60% of the European population excluding the Russian and Turkish parts of Europe, we estimated age stratified all-cause excess morality using the EuroMOMO model. In addition, age stratified all-cause influenza-attributable mortality was estimated using the FluMOMO algorithm, incorporating influenza activity based on clinical and virological surveillance data, and adjusting for extreme temperatures. Results Excess mortality was mainly attributable to influenza activity from December 2017 to April 2018, but also due to exceptionally low temperatures in February-March 2018. The pattern and extent of mortality excess was similar to the previous A(H3N2) dominated seasons, 2014/15 and 2016/17. The 2017/18 overall all-cause influenza-attributable mortality was estimated to be 25.4 (95%CI 25.0-25.8) per 100,000 population; 118.2 (116.4-119.9) for persons aged 65. Extending to the European population this translates into over-all 152,000 deaths. Conclusions The high mortality among elderly was unexpected in an influenza B dominated season, which commonly are considered to cause mild illness, mainly among children. Even though A(H3N2) also circulated in the 2017/18 season and may have contributed to the excess mortality among the elderly, the common perception of influenza B only having a modest impact on excess mortality in the older population may need to be reconsidered.

description: Universal blood pressure (BP) screening in children and adolescents is questioned in prevention guidelines, while measuring blood pressure in the young in the context of overweight, obesity, or parental hypertension is promoted. This study quantifies with population data the underestimation of elevated blood pressure that would result from limiting BP screening only to those with overweight, obesity, or parental hypertension in the young. Selective screening was simulated with representative national health examination data from Germany (age 3-17, N=14,633, KiGGS0 study 2003-2006; age 18-39, N=1,884, DEGS1 2008-2011 study), with mean of two oscillometric measurements on one occasion; cutoffs for hypertensive BP in children were the 95th percentile using KiGGS percentiles, and for sensitivity analyses Fourth Report percentiles, in adults 140/90 mmHg; childhood overweight and obesity were classified according to the International Obesity Task Force and for adults as BMI ≥25 and ≥30 kg/m2. In 3-17-year-olds, different selective BP screening scenarios were simulated: screening only in those with obesity, overweight, parental hypertension, combination of overweight and parental hypertension, resulting in screening 5.6%, 20.0%, 28.5%, and 42.6% of the population and detecting 17.2%, 38.6%, 30.3%, and 58.2% of all hypertensive cases in the population. In conclusion our results show a large screening gap that would result from selective BP screening only in those with overweight, obesity, or parental hypertension.

description: A 5′-tailed duplex (TD) DNA corrects a base-substitution mutation. In this study, the effects of insertion and deletion (indel) mismatches distant from the target position on the gene correction were examined. Three target plasmid DNAs with and without indel mismatches ∼330 bases distant from the correction target position were prepared, and introduced into HeLa cells together with the TD. The indel mismatches improved the gene correction efficiency and specificity without sequence conversions at the indel mismatch site. These results suggested that the gene correction efficiency and specificity are increased when an appropriate second mismatch is introduced into the TD fragment.

description: In this article, we explore the relationship between the role played by Colombian senators from the 2010-2014 and 2014-2018 legislative periods in the network structure of Senate members’ connections on Twitter, and their political power, represented by the number of laws they passed. Using a fixedeffects Poisson model, we find evidence of a positive association between a party’s proportion of seats, eigenvector centrality, closeness centrality, and political power. Conversely, betweenness centrality, eccentricity, and membership in the government coalition appear to be negatively associated with political power.

description: Der Artikel gibt Einblick in die Diskussion um Unterrichtsqualität in der Musikdidaktik. Dazu werden sowohl theoretische als auch empirische Beiträge gesichtet und begründet, warum aufgrund der Pluralität der Konzeptionen und Ansätze in der Musikdidaktik bislang kein verbindliches oder breit geteiltes Modell zur Unterrichtsqualität vorliegt. Am Beispiel der Zielperspektive einer „ästhetischen Musikpraxis“ wird gezeigt, wie theoretische Zugänge vor allem die Fachspezifik von Unterrichtsqualität herausarbeiten. Empirische Beiträge und hier besonders qualitative Videostudien stellen dagegen expliziten Bezug auch zu generischen Dimensionen von Unterrichtsqualität her, bemühen sich dabei aber um eine fachspezifische Modifikation. Vor dem Hintergrund des aktuellen musikdidaktischen Diskurses erfolgt abschließend ein Ausblick auf mögliche Kandidaten für weitere fachspezifische Ergänzungen und Ausdifferenzierungen für das Syntheseframework von Praetorius et al. (2020). Hier wird insbesondere die Ergänzung durch eine Dimension einer „ästhetischen Aktivierung“ angeregt und auf die Berücksichtigung der materialen Dimension eines sinnvollen Umgangs mit Artefakten im Unterricht verwiesen.

description: In the present work, the authors have grown the bulk-sized single crystals of pure (Size ~ 45 × 10 × 10 mm3) and first time L-threonine (LT)-doped (Size ~ 85 × 10 × 8 mm3) KDP with high quality by Sankaranarayana-Ramasamy (SR) method in an aqueous solution at constant temperature. A remarkable enhancement in the growth rate was observed from 3.2 mm/day (pure) to 6 mm/day (LT doped), respectively. The crystal structure, lattice parameters and growth direction were confirmed by powder X-ray diffraction analysis. FT-IR study confirms the presence of L-Threonine doping in KDP. Further, the vibrational modes and surface morphology was studied by FT-Raman spectroscopy along with etching treatment and shows remarkable reduction of surface defects. The optical transparency of SR-grown KDP crystals was found to be enhanced from 76 to 88% due to LT doping. The optical band gap was calculated for both the crystals and found to be 5.68 and 5.53 eV. Crystalline perfection of the grown crystals was assessed by high-resolution X-ray diffraction, dielectric and wet chemical etching studies and found to be good. The obtained result shows that the grown crystals can be used for laser applications.

description: The results of a long-lasting geomorphological survey carried out in Rome are summarized. A method aimed at integrating survey data, historical maps, aerial photographs and archaeological and geomorphological literature produced a geomorphological map of the present-day historical centre. The geomorphology of Rome is related to the paleogeographical conditions prior to the founding of the City; they allow us to recognize the stages of landscape evolution of the ancient Caput Mundi (Capital of the World). The study area has been affected by continuous man-made changes to the drainage network and to the topographic surface over the last 3000 years. It has forced the authors to develop innovative solutions to undertake effective analysis of the urban environment and the legend of the geomorphological map in this peculiar context. The resulting map is useful for urban planning and archaeological research.

description: Objectives: Obesity is a growing issue with increasing impact on healthcare budgets, yet very little is known about weight loss experiences of people with body mass index (BMI)≥30kg/m2 and their willingness to try and pay for weight loss interventions (WLI). The objective of this survey was to gather knowledge about weight loss experiences among obese and severely obese people. Methods: 1,003 Danish people >18 years of age with BMI≥30 who wanted to lose weight completed an online survey. Data included demographics, experience with WLI, awareness of anti-obesity medication (AOM), and willingness to try and pay for WLI including AOM. Results: Respondents had been trying to lose weight for several years (medium [25% percentile;75% percentile]);5.1[2.0;10.3] years (BMI 30-35) and 10.0 [5.0;20.0] (very obese (BMI>35) with co-morbidities (OWC). The desired weight loss was 20.0 [15.0;25.0] kg (BMI 30-35) and 35.0 [28.0;47.5] kg (OWC). Independent of educational level and gender, health concern was the main incentive for weight loss. Several WLI had been tried repeatedly, yet 60% of respondents with BMI 30-35 and 50% of the OWC were unaware of AOM. Among those who had tried AOM, side effects and lack of effectiveness were the main reasons to stop. 50-73% were willing to try AOM dependent on expected weight loss. Willingness to try and pay for new AOM was strongest for the OWC. Conclusion: Respondents had made repeated attempts for up to a decade to lose weight, yet remained far from their ideal weight. They had spent a substantial amount of money on WLI, had limited information of AOM, and indicated a desire for increased professional support.

description: The pathways of water across root tissues and their relative contribution to plant water uptake remain debated. This is mainly due to technical challenges in measuring water flux non-invasively at the cellular scale under realistic conditions. We developed a new method to quantify water fluxes inside roots growing in soils. The method combines spatiotemporal quantification of deuterated water distribution imaged by rapid neutron tomography with an inverse simulation of water transport across root tissues. Using this non-invasive technique, we estimated for the first time the in-situ radial water fluxes [m s−1] in apoplastic and cell-to-cell pathways. The water flux in the apoplast of twelve days-old lupins (Lupinus albus L. cv. Feodora) was seventeen times faster than in the cell-to-cell pathway. Hence, the overall contribution of the apoplast in water flow [m3 s−1] across the cortex is, despite its small volume of 5%, as large as 57 ± 8% (Mean ± SD for n = 3) of the total water flow. This method is suitable to non-invasively measure the response of cellular scale root hydraulics and water fluxes to varying soil and climate conditions.

description: Norway lobsters, Nephrops norvegicus, are sediment-dwelling decapod crustaceans that excavate burrows from which they make short excursions to feed by predation and scavenging. The females of this species are known to reside within their burrows for an extended period of time over the winter while brooding their eggs. The aim of this study was to assess the likelihood of these females being able to feed during this brooding period. Biophysical and biochemical measurements that had previously been shown to change with starvation under laboratory conditions in male N. norvegicus were taken for female N. norvegicus under similar conditions. These measurements were also compared in both sexes obtained from monthly trawl samples from the Clyde Sea Area, Scotland, UK, together with trawl composition data. The laboratory study showed that the hepatosomatic index, and the copper, lipid and water content of the hepatopancreas can be used as indicators of the state of starvation in females, as in males. In the wild, both sexes have reduced nutritional status during the winter, but not to the degree seen in animals starved for 20 weeks in aquarium trials. This study does not support the hypothesis that females cease feeding over winter, during their brooding period. Firstly, some females were unable to sustain ovary development during starvation under controlled conditions, contrary to field observations. Secondly, field data suggest that there is no sex-specific reduction in nutritional status.

description:  

Soybean (Glycine max) is recognized for its nutritional significance due to its high protein and lipid content. The unique presence of isoflavonoids in leguminous plants, particularly soybeans, distinguishes them as promising bioactive compounds. Isoflavonoids, such as genistein, daidzein, and glycitein, are known to exhibit antibacterial properties. However, their potential antiviral activity against plant viruses, specifically ToLCKV, remains largely unexplored. This study aimed to investigate the impact of isoflavonoids on ToLCKV infection in Nicotiana benthamiana, a model plant species. Seeds of N. benthamiana were primed with mixture of genistein, daidzein, glycitein, and water (control). Subsequently, seedlings were inoculated with infectious clones of Tomato leaf curl Karnataka virus (ToLCKV) using the agroinoculation method at 4 leaf stage. Leaves from both primed and unprimed plants were collected for DNA isolation. Real-time PCR was then employed to quantify the abundance of ToLCKV in primed and control plants. The absolute quantification of viral load was assessed and calculated using a standard graph of viral DNA dilutions. The results of the real-time quantification of viral load indicated a 28-fold reduction in the viral load of primed plants compared to the unprimed plants. This observation suggests that isoflavonoids from soybeans, namely genistein, daidzein, and glycitein, possess antiviral activity against ToLCKV. This study provides valuable insights into the potential application of soybean isoflavonoids as natural antiviral agents in agriculture, particularly for the management of ToLCKV infections that pose a substantial threat to pulse crops. Further research is warranted to elucidate the underlying mechanisms of isoflavonoid action and to explore their broader applicability in the field of plant virology.

description: Reverse transcription describes the process of the transformation of single-stranded RNA into double-stranded DNA via an RNA/DNA duplex intermediate, and is catalyzed by the viral enzyme reverse transcriptase (RT). This event is a pivotal step in the life cycle of all retroviruses. In contrast to orthoretroviruses, the domain structure of the mature RT of foamy viruses is different, i.e., it harbors the protease (PR) domain at its N-terminus, thus being a PR-RT. This structural feature has consequences on PR activation, since the enzyme is monomeric in solution and retroviral PRs are only active as dimers. This review focuses on the structural and functional aspects of simian and prototype foamy virus reverse transcription and reverse transcriptase, as well as special features of reverse transcription that deviate from orthoretroviral processes, e.g., PR activation.

description: Coastal ecosystems suffer substantially from the worldwide population growth and its increasing land demands. A common approach to investigate anthropogenic disturbance in coastal ecosystems is to compare urbanized areas with unaffected control sites. However, the question remains whether different types of anthropogenic disturbance that are elements of an urbanized area have the same impact on beach ecosystems. By investigating small islands that are utilized for tourism, inhabited by the local population, or remained completely uninhabited, we disentangled different anthropogenic disturbances and analysed their impacts on hermit crabs as indicator species. We observed a negative impact on abundance on tourist islands and a negative impact on body size on local islands. In comparison to the uninhabited reference, both disturbances had an overall negative impact. As both forms of disturbance also impacted the underlying food resource and habitat availability differently, we propose that the findings from our study approach are valid for most obligate beach species in the same system. This demonstrates that in urbanized areas, the coastal ecosystem is not always impacted identically, which emphasizes the importance of considering the particular type of anthropogenic disturbance when planning conservation action in urbanized areas.

The complexes were characterized by the elemental analysis, mass spectrometry, infrared, and multinuclear (1H, 13C and 195Pt) 1-D and 2-D NMR spectroscopies, and by single-crystal X-ray analysis of [Pt(4-Mebpy)I2] (4). All the platinum(II) complexes (1–6) were evaluated for in vitro cytotoxicity against human cancer cell lines A2780 and A2780R, and against non-malignant MRC5 cell line. All the complexes were nontoxic up to the 50 μM concentration, although they were found to readily bind to calf-thymus DNA (CT-DNA), as determined by spectrophotometric titration (Kb ≈ 107 M−1) and ethidium bromide displacement assay.

description: Microorganisms mobilize phosphorus (P) in soil by solubilizing bound inorganic P from soil minerals and by mineralizing organic P via phosphatase enzymes. Nitrogen (N) inputs are predicted to increase through human activities and shift plants to be more P limited, increasing the importance of P mobilization processes for plant nutrition. We studied how the relative abundance of P-solubilizing bacteria (PSB), PSB community composition, and phosphatase activity respond to N and P addition (+N, +P, +NP) in grassland soils spanning large biogeographic gradients. The studied soils are located in South Africa, USA, and UK and part of a globally coordinated nutrient addition experiment. We show that the abundance of PSB in the topsoil was reduced by −18% in the N and by −41% in the NP treatment compared to the control. In contrast, phosphatase activity was significantly higher in the N treatment than in the control across all soils. Soil C:P ratio, sand content, pH, and water-extractable P together explained 71% of the variance of the abundance of PSB across all study sites and all treatments. Further, the community of PSB in the N and NP addition treatment differed significantly from the control. Taken together, this study shows that N addition reduced the relative abundance of PSB, altered the PSB community, and increased phosphatase activity, whereas P addition had no impact. Increasing atmospheric N deposition may therefore increase mineralization of organic P and decrease solubilization of bound inorganic P, possibly inducing a switch in the dominant P mobilization processes from P solubilization to P mineralization.

description: Naphthalimide-based ligands have received significant attention for their ability to act as secondary building units for metal containing network structures. The potentially bridging 1,2,4-triazole containing N-(1,2,4-triazolyl)-1,8-naphthalimide (L1) and N-(1,2,4-triazolyl)-4-dimethylamino-1,8-naphthalimide (L2) were prepared, characterized, and complexed with Cu(II) salts. L1 resulted in crystallographically characterized dinuclear complexes, [Cu2(L1)4(NO3)4] and [Cu2(L1)2(OAc)4] when reacted with Cu(NO3)2 and Cu2(OAc)4, respectively. Packing interactions are dominated by π⋯π and anion⋯π interactions and gave rise to structure extension through weak supramolecular interactions. Solid state EPR and magnetism measurements on [Cu2(L1)4(NO3)4] revealed the expected values for a non-magnetically coupled square-based pyramidal dimer structure, while [Cu2(L1)2(OAc)4] showed strong anti-ferromagnetic coupling (JCu–Cu = −185.6 cm−1).
