description: Tribe Brassiceae (haploid chromosome number, n=6$-$75) is generally recognized as one of the few natural (monophyletic) groups in the Brassicaceae. Recent molecular analyses, however, have questioned the validity of this subtribal classification and have proposed new generic and subtribal circumscriptions. The present study examined isozyme number, which is usually highly conserved in diploid plants, in order to assess the evolution of chromosome number and systematic relationships in the tribe. Ten enzyme systems were surveyed for 108 species in 35 genera of tribe Brassiceae and for eleven species from seven other tribes of the family. The observed variation in isozyme number among taxa was phylogenetically informative. Duplications for cytosolic phosphoglucomutase (Pgm-2) and plastid triosephosphate isomerase (Tpi-1) were evident in 33 of the 35 Brassiceae genera examined, supporting the monophyletic nature of the tribe, with inclusion of Orychophragmus and exclusion of Calepina and Conringia. Duplications for cytosolic isocitrate dehydrogenase (Idh-2) were observed in members of Brassica, Diplotaxis, Moricandia and Pseuderucaria, confirming that subtribes Moricandiinae and Brassicinae are artificially separated, as indicated by restriction site analysis of chloroplast DNA and hybridization data. The only subtribe clearly supported as monophyletic by the isozyme data was the Cakilinae which displayed duplications for cytosolic glucose-6-phosphate isomerase (Gpi-2) and Idh-2 in several taxa. The present study also compared allozyme patterns of select allopolyploids and their proposed parental species. These analyses verified Diplotaxis tenuifolia (n = 11) and D. viminea (n = 10), and D. erucoides (n = 7) and Erucastrum nasturtiifolium (n = 8) as respective parental taxa of D. muralis (n = 10 + 11) and E. gallicum (n = 7 + 8). In addition, inheritance studies conducted on Sinapis arvensis confirmed Mendelian inheritance at seven isozyme loci.

description: Motivated by the recent, serendipitous discovery of the densest known galaxy, M60-UCD1, we present two initial findings from a follow-up search, using the Sloan Digital Sky Survey, Subaru/Suprime-Cam, and Hubble Space Telescope imaging, and SOuthern Astrophysical Research (SOAR)/Goodman spectroscopy. The first object discovered, M59-UCD3, has a similar size to M60-UCD1 (half-light radius of rh ∼ 20 pc) but is 40% more luminous (MV ∼ -14.6), making it the new densest-known galaxy. The second, M85-HCC1, has a size like a typical globular cluster (GC; rh ∼ 1.8 pc) but is much more luminous (MV ∼ -12.5). This hypercompact cluster is by far the densest confirmed free-floating stellar system, and is equivalent to the densest known nuclear star clusters. From spectroscopy, we find that both objects are relatively young (∼9 and ∼3 Gyr, respectively), with metal-abundances that resemble those of galaxy centers. Their host galaxies show clear signs of large-scale disturbances, and we conclude that these dense objects are the remnant nuclei of recently accreted galaxies. M59-UCD3 is an ideal target for follow-up with high-resolution imaging and spectroscopy to search for an overweight central supermassive black hole as was discovered in M60-UCD1. These findings also emphasize the potential value of ultra-compact dwarfs and massive GCs as tracers of the assembly histories of galaxies.

description: Investment in 'next generation' (very high speed) broadband infrastructure is expected to enable access to services that will provide citizens with social and economic benefits. Developing services for access using broadband infrastructure can be quite complicated however. This paper explores how services can be delivered over broadband network infrastructure, outlining four broad categories of access devices, three service delivery platforms and two types of networks. Using Australian data, the paper explores user behaviours and expectations around service delivery, illustrating the need for diversity and choice of service offerings. It also notes the importance of mobile services, and makes the case that wireless broadband connectivity should be part of a national broadband infrastructure.

description: Background: At the time of an infant’s initial vaccination at age ~2–3 months, some infants already have maternal antibodies against vaccine antigens and these can suppress the immune response to vaccination. Modelling the effects of maternal antibody and the timing of infant doses on the antibody response to vaccination, requires estimates of the rate of maternal antibody decay. Decay rates are not well characterised in the medical literature. We investigated variation in the prevalence of maternal anti-capsular pneumococcal and meningococcal antibodies in infants in 14 countries, and estimated type-specific half-lives. Methods: Individual participant serological data were obtained from clinical trials. Half-lives were estimated from antibody concentrations in infants who did not receive meningococcal or pneumococcal vaccines. Results: The seroprevalence of maternal pneumococcal antibodies was highest for serotypes 14, and 19F (92% and 80% respectively) and lowest for serotypes 4 and 1 (30% and 34% respectively). Half-life estimates ranged from 38.7 days (95%CI 36.6–41.0) for serotype 6B, to 48.3 days (95%CI 46.7–50.2) for serotype 5. The overall half-life was 42.6 days (95%CI 41.5–43.7). Seroprevalence was highest in Mali, Nigeria, India, and the Philippines, (all> 65%) and lowest in the Czech Republic and Finland (both<45%). In studies of meningococcal vaccines, seroprevalence was 13% for group C (half-life 39.8 days, 95%CI 33.4–49.4) and 43% for group A (half-life 43.1 days 95%CI 39.8–47.2). Conclusion: Substantial proportions of infants in many countries have antibodies to vaccine serotypes of pneumococcus, however fewer infants have maternally acquired antibodies to groups A and C meningococcus. Passively-acquired antibodies to capsular polysaccharides decay with a half-life of approximately 6 weeks. These estimates are useful for modelling the impact of proposed vaccination programmes, and consideration of schedules with a delayed start.

description: We study the color-magnitude red sequence and blue fraction of 72 X-ray selected galaxy clusters at z = 0.04-0.07 from the WINGS survey, searching for correlations between the characteristics of the red sequence (RS) and the environment. We consider the slope and scatter of the red sequence, the number ratio of red luminous-to-faint galaxies, the blue fraction, and the fractions of ellipticals, S0s, and spirals that compose the RS. None of these quantities correlate with the cluster velocity dispersion, X-ray luminosity, number of cluster substructures, BCG prevalence over next brightest galaxies, and the spatial concentration of ellipticals. The properties of the RS, instead, depend strongly on local galaxy density. Higher density regions have a smaller RS scatter, a higher luminous-to-faint ratio, a lower blue fraction, and a lower spiral fraction on the RS. Our results clearly illustrate the prominent effect of the local density in setting the epoch when galaxies become passive and join the red sequence, as opposed to the mass of the galaxy host structure.

description: Aims Optimization of the AV-interval (AVI) in DDD pacemakers improves cardiac hemodynamics and reduces pacemaker syndromes. Manual optimization is typically not performed in clinical routine. In the present study we analyze the prevalence of E/A wave fusion and A wave truncation under resting conditions in 160 patients with complete AV block (AVB) under the pre-programmed AVI. We manually optimized sub-optimal AVI. Methods We analyzed 160 pacemaker patients with complete AVB, both in sinus rhythm (AV-sense; n = 129) and under atrial pacing (AV-pace; n = 31). Using Doppler analyses of the transmitral inflow we classified the nominal AVI as: a) normal, b) too long (E/A wave fusion) or c) too short (A wave truncation). In patients with a sub-optimal AVI, we performed manual optimization according to the recommendations of the American Society of Echocardiography. Results All AVB patients with atrial pacing exhibited a normal transmitral inflow under the nominal AV-pace intervals (100%). In contrast, 25 AVB patients in sinus rhythm showed E/A wave fusion under the pre-programmed AV-sense intervals (19.4%; 95% confidence interval (CI): 12.6–26.2%). A wave truncations were not observed in any patient. All patients with a complete E/A wave fusion achieved a normal transmitral inflow after AV-sense interval reduction (mean optimized AVI: 79.4 ± 13.6 ms). Conclusions Given the rate of 19.4% (CI 12.6–26.2%) of patients with a too long nominal AV-sense interval, automatic algorithms may prove useful in improving cardiac hemodynamics, especially in the subgroup of atrially triggered pacemaker patients with AV node diseases.

description: We present the morphological catalogue of galaxies in nearby clusters of the WIde-field Nearby Galaxy-clusters Survey (WINGS). The catalogue contains a total number of 39 923 galaxies, for which we provide the automated estimates of the morphological type, applying the purposely devised tool MORPHOT to the V-band WINGS imaging. For ∼3000 galaxies we also provide visual estimates of the morphological type. A substantial part of the paper is devoted to the description of the MORPHOT tool, whose application is limited, at least for the moment, to the WINGS imaging only. The approach of the tool to the automation of morphological classification is a non-parametric and fully empirical one. In particular, MORPHOT exploits 21 morphological diagnostics, directly and easily computable from the galaxy image, to provide two independent classifications: one based on a maximum likelihood (ML), semi-analytical technique and the other one on a neural network (NN) machine. A suitably selected sample of ∼1000 visually classified WINGS galaxies is used to calibrate the diagnostics for the ML estimator and as a training set in the NN machine. The final morphological estimator combines the two techniques and proves to be effective both when applied to an additional test sample of ∼1000 visually classified WINGS galaxies and when compared with small samples of Sloan Digital Sky Survey (SDSS) galaxies visually classified by Fukugita et al. and Nair et al. Finally, besides the galaxy morphology distribution (corrected for field contamination) in the WINGS clusters, we present the ellipticity (ɛ), colour (B−V) and Sersic index (n) distributions for different morphological types, as well as the morphological fractions as a function of the clustercentric distance (in units of R200).

description: The development of drugs that can inactivate disease-causing cells (e.g. cancer cells or parasites) without causing collateral damage to healthy or to host cells is complicated by the fact that many proteins are very similar between organisms. Nevertheless, due to subtle, quantitative differences between the biochemical reaction networks of target cell and host, a drug can limit the flux of the same essential process in one organism more than in another. We identified precise criteria for this ‘network-based’ drug selectivity, which can serve as an alternative or additive to structural differences. We combined computational and experimental approaches to compare energy metabolism in the causative agent of sleeping sickness, Trypanosoma brucei, with that of human erythrocytes, and identified glucose transport and glyceraldehyde-3-phosphate dehydrogenase as the most selective antiparasitic targets. Computational predictions were validated experimentally in a novel parasite-erythrocytes co-culture system. Glucose-transport inhibitors killed trypanosomes without killing erythrocytes, neurons or liver cells.

description: Background Numerous information models for electronic health records, such as openEHR archetypes are available. The quality of such clinical models is important to guarantee standardised semantics and to facilitate their interoperability. However, validation aspects are not regarded sufficiently yet. The objective of this report is to investigate the feasibility of archetype development and its community-based validation process, presuming that this review process is a practical way to ensure high-quality information models amending the formal reference model definitions. Methods A standard archetype development approach was applied on a case set of three clinical tests for multiple sclerosis assessment: After an analysis of the tests, the obtained data elements were organised and structured. The appropriate archetype class was selected and the data elements were implemented in an iterative refinement process. Clinical and information modelling experts validated the models in a structured review process. Results Four new archetypes were developed and publicly deployed in the openEHR Clinical Knowledge Manager, an online platform provided by the openEHR Foundation. Afterwards, these four archetypes were validated by domain experts in a team review. The review was a formalised process, organised in the Clinical Knowledge Manager. Both, development and review process turned out to be time- consuming tasks, mostly due to difficult selection processes between alternative modelling approaches. The archetype review was a straightforward team process with the goal to validate archetypes pragmatically. Conclusions The quality of medical information models is crucial to guarantee standardised semantic representation in order to improve interoperability. The validation process is a practical way to better harmonise models that diverge due to necessary flexibility left open by the underlying formal reference model definitions. This case study provides evidence that both community- and tool- enabled review processes, structured in the Clinical Knowledge Manager, ensure archetype quality. It offers a pragmatic but feasible way to reduce variation in the representation of clinical information models towards a more unified and interoperable model.
Broadband transformation through improved support systems

description: Telecommunications transformation is business driven, focusing upon operational efficiency, next generation networks, and market agility for new broadband products and services. Much of the activity has resulted in significant upgrades of the Business Support Systems (BSS) and Operational Support Systems (OSS). These systems have traditionally provided support for a wide range of products, with the spotlight on voice and data services. The influence of multimedia service delivery has now placed additional transformation pressure upon operators, with this form of content supported by a set of Delivery Support Systems (DSS). We have conducted a global survey of the scope and breadth of operator transformation of the three domains (OSS, BSS, & DSS) in practice, and present the results from that survey. The results provide insight into the scope of transformation and the level to which standards and frameworks are applied within the industry. Based upon these inputs we also present a design blueprint of these three domains co-existing, illustrating the functional scope of present day transformation for operators. This information may be useful to existing operators as well as new broadband operators entering the market.

description: In an era marked by dynamic shifts in social identities, literature emerges as a conduit for cultivating understanding, empathy, and self-awareness. This dissertation is a transformative exploration of Critical Literature Pedagogy (CLP) and the concepts of ‘performativity’ and ‘trans identity’ within queer theory. With a focus on fostering inclusive learning environments, this study employs CLP as a lens to explore the notion of performativity in texts and education. Central to this dissertation is the development of a pedagogical framework created to analyze texts, encompassing both written and multimedia formats, through the lens of performativity and trans identity. The developed pedagogical method uses science fiction as a primary example for illustrating functionality. However, the method’s adaptability across genres, medias, and subjects is underscores its broad applicability. Through the pedagogical approach, students are then empowered to engage critically with texts, gaining insight into the construction of meaning and the interplay of identity markers. This dissertation not only advances pedagogical scholarship but contributes to the broader discussion on inclusivity, representation, accessibility, and identity within educational contexts. By bridging theory with practice, the developed method offers a roadmap for educators to navigate the complexities of contemporary society through critical engagement with literature.

description: This study, conducted as a needs assessment, was guided by O'Connor's Decision Support Framework (DSF). The DSF describes a process of providing to both parents and practitioners decision support by identifying the sub-optimal determinants of the decision. The objectives of the study were to describe the decision making needs of parents making choices about neonatal male circumcision and the needs of prenatal instructors who inform parents about options. The study design was across-sectional survey of 88 mothers and 67 fathers and 10 prenatal instructors. Structured questionnaires were used, eliciting variables based on the DSF, such as: the perception of the decision; perception of others regarding the decision; resources to make the decision; and participant characteristics. Although all instructors stated that circumcision was discussed, the content of the discussion varied according to the instructor's experience and perception of the decision. Most instructors (9/10) believed parents lacked both information about options and chances of the benefits and risks. Few of the instructors (2/10) saw their role as instrumental in the decision.

description: Background Surgical treatment of adolescent idiopathic scoliosis (AIS) is very complex and modern instrumentation techniques offer multiple possibilities. Despite numerous publications, there is no clear consensus on the optimal strategy for the correction of scoliotic deformities. The goal of this study was to summarize the current surgical strategies for specific AIS cases within various countries. Method Thirty-two experienced scoliosis surgeons from 15 countries were asked to plan surgeries on 12 representative AIS cases. All AIS cases had an indication for surgery. A questionnaire was provided to document surgical planning. The surgeons were provided with the patients' age and sex, together with radiographs in the lateral and sagittal planes during upright standing and in lateral bending to the left and right, as well as with clinical images. The angles of the main spinal curvatures were specified in the questionnaire. The surgeons were asked to specify their preferred classification system, their surgical approach, the planned fusion length, the type of implants, the rod type, and the resection steps. The data were analyzed with respect to the inter-rater variability, which was quantified using the Fleiss-Kappa Method. Results There was a good agreement (k = 0.61) between the surgeons in choosing the Lenke curve type, and a moderate agreement for the lumbar (0.41) and sagittal (0.56) modifiers. The most frequently planned resection procedure was complete facetectomy (67%). The posterior approach was the most commonly (91%) selected strategy to treat AIS. Anterior approaches were chosen most for Lenke 5 type with a rate of 20%. The upper instrumented vertebra (UIV) varied most for Lenke 1, 5, and 6 cases, with a vertebral level discrepancy of up to 10 levels at Lenke 6. The lowest instrumented vertebra varied most for Lenke 1 and 4 by up to five levels. Polyaxial screws were chosen most (56%), followed by monoaxial (20%) and uniplanar (19%) screws and hooks (5%). Conclusions The results highlight the commonalities and discrepancy in the surgical treatment of AIS in between surgeons. The selected LIV and UIV can vary depending on the curve type and surgeon. Hook constructs appear to be generally replaced by transpedicular screws. The survey indicates open questions in the AIS treatment and in the understanding of scoliosis biomechanics.

description: A series of wind tunnel tests was conducted to investigate the existence of the galloping instability of inclined dry cables and also to identify the influence of some parameters on it. These parameters are the structural damping and cable surface roughness, which may have significant impact on the vibration characteristics. The test results showed both the divergent type of galloping instability and the limited amplitude high wind speed vortex shedding excitation. Galloping instability was observed in only one case. Parametric study shows that the vortex shedding oscillation can be easily suppressed with an increase of the structural damping. It was also shown that the instability criterion indicated by earlier research was too conservative compared to the results obtained from the present study.
Pathways for Participatory Water Governance in Ashaiman, Ghana : Learning from Institutional Bricolage and Hydrosocial Perspectives

description: Coupling a hydrosocial perspective with institutional bricolage, this research considers possibilities for participatory water governance in Ashaiman, a peri-urban settlement of Accra, Ghana. We explore three questions: (1) How do people in Ashaiman evoke ideas or experiences of water in general and water governance in particular? (2) What possibilities currently exist for engaging the community in key water-related decisions? (3) What possibilities exist for enhanced participatory water governance in this context, including potential for and interest in new institutions and engagement processes? Results of qualitative interviews and semistructured observation suggest that a siloed, water-centric approach inadequately captures everyday realities of water as hydrosocial and of existing institutions in Ashaiman. In contrast to “modern water,” we propose that water issues may be more meaningfully addressed as bundled with social welfare. Potential implications and alternative ways of understanding socio-institutional arrangements for participatory water governance are explored.

description: As a result of increasing environmental regulations, navies and the marine industry have been required to install effective Oily Water Separation (OWS) systems capable of providing an effluent containing no more than 15 parts per million (ppm) oil and grease. However, due to the complex nature of bilge water it has proven difficult to develop a system capable of achieving these environmental standards while also addressing the marine constraints of compactness, robustness and automation. This work has investigated the particulate loading of bilge water and the impact of its various components on the effectiveness of a membrane based treatment system. Additionally, various means of minimizing the decline in trans-membrane flux associated with the particulate loading of bilge water were examined. Pilot scale testing was performed to better simulate shipborne conditions. Two membranes were tested: a ceramic membrane with a pore diameter of 0.005 microns and a polyacrylo nitrite membrane with a Molecular Weight Cut-off of 50,000 Daltons. The average run lasted 24 hours and the membranes were cleaned after each run. Backflushing was tested as a means of trans-membrane flux enhancement. (Abstract shortened by UMI.)

description: The transcription factor NF-E2-related factor 2 (Nrf2) induces cytoprotective genes, but has also been linked to the regulation of hepatic energy metabolism. In order to assess the pharmacological potential of hepatic Nrf2 activation in metabolic disease, Nrf2 was activated over 7 weeks in mice on Western diet using two different siRNAs against kelch-like ECH-associated protein 1 (Keap1), the inhibitory protein of Nrf2. Whole genome expression analysis followed by pathway analysis demonstrated successful knock-down of Keap1 expression and induction of Nrf2-dependent genes involved in anti- oxidative stress defense and biotransformation, proving the activation of Nrf2 by the siRNAs against Keap1. Neither the expression of fatty acid- nor carbohydrate-handling proteins was regulated by Keap1 knock-down. Metabolic profiling of the animals did also not show effects on plasma and hepatic lipids, energy expenditure or glucose tolerance. The data indicate that hepatic Keap1/Nrf2 is not a major regulator of glucose or lipid metabolism in mice.

description: The distribution, morphometry and biophysical characteristics of turf-banked lobes and terraces are described from a small subarctic alpine plateau (1300--1900 m a.s.l.) overlooking Kluane Lake in the southwest Yukon Territory, Canada. Observations on the distribution of lobes and terraces at this site indicate that the main controlling factors are the complexity of the topography and the properties of snow cover. Morphometric analysis of 85 lobes subdivided into five different slope orientations indicates a morphogenetic underpinning in which lobe form remains consistent (length-to-width ratio below unity) at different scales and between aspects, however, morpho-biophysical correlations could not provide an explanation for this. Nonparametric and multivariate parametric statistical tests indicate significant inter-aspect differences in the dimensions and biophysical characteristics of the lobes. These appear to be related to differences in site-specific factors. Measurements made along certain transects reveal a definitive downslope trend in the size of lobes. This organization is developed as a result of downslope gradients of various biophysical factors, primarily soil moisture and frost-susceptible soil (silt and clay), which are created by slopewash processes.

description: This study leverages information manipulation theory to investigate the association between decreased readability (obfuscation) of tabulated financial data within the annual report and deception. Using a sample of over 9,000 firm-year observations, I leverage artificial intelligence to automatically classify financial tables within the 10-K and a novel method of measuring visual readability to determine if accruals earnings management and real-activities management are significantly associated with the readability of tabulated financial data. Results demonstrate that firms with higher levels of accruals management and that meet or just beat prior year earnings tend to have tabulated financial data within the 10-K, and in particular the audited financial statements, that are less readable. Results also provide evidence that firms with higher levels of real-activities management tend to have tabulated data within the supplementary disclosures of the audited financial statements that are less readable. Furthermore, firms that restate their financial statements with the filing of an 8-K or that are subject to an investigation by the Securities and Exchange Commission also have audited financial statements that are less readable, and the dollar magnitude of such restatements for specific accounts varies proportionately with the increase in visual complexity for the primary financial statement tied to that account. Taken together, these findings provide evidence that firms which are manipulating earnings consistent with the process and outcome of earnings management tend to have tabulated financial data that appears obfuscated. Furthermore, this obfuscation appears to be prevalent in both the reviewed sections of the 10-K and the audited financial statements.

description: The introduction of Chronic Disease Management (CDM) Medicare items and use of information technology (IT) has had an impact on GPs, patients and health professionals. As e-health initiatives are implemented, concerns have been noted about patients' variability in computer and mobile phone ownership, skills and use. The aim of this research was to investigate patients' use of, attitudes to and beliefs about webbased care planning, using a combination of questionnaire and interviews. Similar levels of computer and mobile phone ownership were reported. Although two-thirds of the cohort of 99 participants used the Internet, hardly any (1%) used the Internet to upload their glucose readings and very few (0.05%) 'often' used their mobile phones to receive and/or send SMS messages. Conclusion: the reluctance by patients to become directly involved in web-based health records might be due in part to their limited use of the Internet and mobile phones, although other factors also need to be explored.

description: Although biotechnology is a relatively a new industry it is expected to have a major impact on our economy and society in the near future. The field of medicine will be affected dramatically. The spin-off phenomenon is also relatively new. Little information has been available on their effect, especially on a national basis. As a study of medical and biomedical companies created from technology developed in Canada's medical schools and affiliated research institutes, this thesis set out to answer five questions related to biotechnology and spin-offs. The five questions follow: (1) Which Canadian companies are biomedical spin-offs? (2) Who funded the founding technology of biomedical spin-off companies and the careers of the founding scientists? (3) What is the rate of spin-off creation? (4) How are these spin-off companies impacting the economy? (5) Which provinces have been "players" in this industry? (Abstract shortened by UMI.)

description: Fast 80 % der 322 Kommunen, die an einer bundesweiten Umfrage teilgenommen haben, führten im Jahr 2017 eine Rattenbekämpfung in der Kanalisation durch. Dazu wurden überwiegend Formköder mit Antikoagulanzien der zweiten Generation am Draht in den Kanalschacht gehängt. Die Bekämpfung erfolgte häufig nach Meldung eines Rattenbefalls aus der Bevölkerung, aufgrund von Eigenüberwachung oder präventiv in (halb)jährlichem Turnus. Lediglich 31,4 % der Ratten bekämpfenden Kommunen führten eine vorherige Befallserhebung durch. Insgesamt wurden bei den teilnehmenden Kommunen 44 t Köder bzw. 5,4 kg Wirkstoff im Jahr 2017 zur Kanalbeköderung eingesetzt. Hochgerechnet auf das gesamte Bundesgebiet ergibt das somit rund 225 t Köder bzw. 32 kg Wirkstoff. Verglichen mit Daten aus einer Umfrage von 2008 reduzierten sich die Einsatzmengen deutlich. Dies wird auf die im Jahr 2012 erstmals rechtsverbindlich festgelegten Anwendungsbestimmungen und Risikominderungsmaßnahmen für antikoagulante Rodentizide zurückgeführt.

description: Almost 80 % of the 322 municipalities involved in a nationwide survey carried out rat control measures in their sewer systems in 2017. In general, bait blocks containing second-generation anticoagulants were deployed in sewer manholes by wire. Rat control frequently took place in sewers after the public reported rat sightings, following self-monitoring, or as a result of regular (semi)annual preventive measures. Just 31.4 % of the municipalities carrying out rat control conducted monitoring prior to application of rodenticides to confirm the presence of rats. All told, the municipalities involved used a total of 44 metric tons of bait material and 5.4 kg of active ingredients in 2017 during sewer baiting. This extrapolates to approximately 225 t of bait and 32 kg of active ingredients for Germany as a whole. The amount of bait used had fallen sharply compared to survey data from 2008, likely due to the implementation of legally binding instructions for use and risk mitigation measures for anticoagulant rodenticides starting from 2012.

description: A mesoscopic analytical model of wrinkling of Plain-Woven Composite Preforms (PWCPs) under the bias extension test is presented, based on a new instability analysis. The analysis is aimed to facilitate a better understanding of the nature of wrinkle formation in woven fabrics caused by large in-plane shear, while it accounts for the effect of fabric and process parameters on the onset of wrinkling. To this end, the mechanism of wrinkle formation in PWCPs in mesoscale is simplified and an equivalent structure composed of bars and different types of springs is proposed, mimicking the behavior of a representative PWCP element at the post-locking state. The parameters of this equivalent structure are derived based on geometric and mechanical characteristics of the PWCP. The principle of minimum total potential energy is employed to formluate the model, and experimental validation is carried out to reveal the effectiveness of the derived wrinkling prediction equation.

description: Excessive daytime sleepiness (EDS) is the most common presenting symptom to sleep medicine clinics and has major socio-economic consequences in industrialized societies. Several approaches have been developed to assess EDS including subjective estimates, performance effects and the rapidity of falling asleep (sleep latency) under standardized conditions, most frequently as the Multiple Sleep Latency Test (MSLT). All have definite drawbacks. It is well known, however, that the on-going EEG is sensitive to variations in alertness/sleepiness levels. This project tested the applications of quantified EEG to the detection and analysis of alertness/sleepiness levels as measured by the MSLT. Twelve age and gender matched normal subjects under rested and (one night) sleep deprived conditions and twelve sleepy untreated obstructive sleep apnea (OSA) patients underwent quantitative EEG analyses immediately before MSLT nap sessions. Mean sleep latency was significantly shorter as one compares rested controls, OSA patients and sleep-deprived controls. At both the O1 and O2 electrode sites (referential recording), the Alpha Attenuation Test (AAT) showed significantly lower AAT values as one compares rested controls, sleep-deprived controls and OSA patients. The values of absolute spectral power for the two theta bands were significantly higher in sleep deprived control subjects than in rested controls. There was an increase of absolute power spectral values for all frequency bands in OSA patients compared to rested and sleep deprived normal subjects. The significant differences between three groups in individual electrode sites were not as strong and consistent as were the total (mean of 8 electrodes) values. These results demonstrate that spectral analysis can be a sensitive measure of EDS. However, its ability to diagnose sleepiness remains uncertain. Further studies are warranted.

description: To improve the understanding of the virome diversity of riverine ecosystems in metropolitan areas, a metagenome analysis was performed with water collected in June 2018 from the river Havel in Berlin, Germany. After enrichment of virus particles and RNA extraction, paired-end Illumina sequencing was conducted and assignment to virus groups and families was performed. This paper focuses on picorna-like viruses, the most diverse and abundant group of viruses with impact on human, animal, and environmental health. Here, we describe altogether 166 viral sequences ranging in size from 1 to 11.5â€ kb. The 71 almost complete genomes are comprised of one candidate iflavirus, one picornavirus, two polycipiviruses, 27 marnaviruses, 27 dicistro-like viruses, and 13 untypeable viruses. Many partial picorna-like virus sequences up to 10.2â€ kb were also investigated. The sequences of the Havel picorna-like viruses represent genomes of seven of eight so far known Picornavirales families. Detection of numerous distantly related dicistroviruses suggests the existence of additional, yet unexplored virus groups with dicistronic genomes, including few viruses with unusual genome layout. Of special interest is a clade of dicistronic viruses with capsid protein-encoding sequences at the 5'-end of the genome. Also, monocistronic viruses with similarity of their polymerase and capsid proteins to those of dicistroviruses are interesting. A second protein with NTP-binding site present in the polyprotein of solinviviruses and related viruses needs further attention. The results underline the importance to study the viromes of fluvial ecosystems. So far acknowledged marnaviruses have been isolated from marine organisms. However, the present study and available sequence data suggest that rivers and limnic habitats are relevant ecosystems with circulation of marnaviruses as well as a plethora of unknown picorna-like viruses. © 2022 Zell, Groth, Selinka and Selinka
