Markers of identification in Indigenous academic writing: A case study of genre innovation
Authors: Makmillen Shurli , Riedlinger Michelle 
Published: August 2020

AbstractThis study contributes to research into genre innovation and scholarship exploring how Indigenous epistemes are disrupting dominant discourses of the academy. Using a case study approach, we investigated 31 research articles produced by Mäori scholars and published in the journalAlterNativebetween 2006 and 2018. We looked for linguistic features associated with self-positioning and self-identification. We found heightened ambiguous uses of “we”; a prevalence of verbs associated with personal (as opposed to discursive) uses of “I/we”; personal storytelling; and a privileging of Elders’ contributions to the existing state of knowledge. We argue these features reflect and reinforce Indigenous scholars’ social relations with particular communities of practice within and outside of the academy. They are also in keeping with Indigenous knowledge-making practices, protocols, and languages, and signal sites of negotiation and innovation in the research article. We present the implications for rhetorical genre studies and for teaching academic genres.
An overview of procalcitonin in Crimean-Congo hemorrhagic fever: clinical diagnosis, follow-up, prognosis and survival rates
Authors: Ekici-Günay Nahide , Koyuncu Serhat 
Published: August 2020

AbstractObjectivesThis study investigates whether a diagnostic threshold value of procalcitonin exists in Crimean-Congo hemorrhagic fever (CCHF), while also determining the correlation between serum procalcitonin and routine diagnostic laboratory markers, monitoring changes in procalcitonin levels over time during hospitalization, and exploring the effect of procalcitonin levels on survival rates.MethodsA total of 161 patients, including 100 with laboratory-confirmed diagnosis of CCHF and 61 as a control group, were retrospectively investigated. Receiver operating characteristics (ROC) curve analysis was performed to evaluate the contribution of procalcitonin when diagnosing the onset in CCHF patients. Procalcitonin levels were measured with Diazyme latex-enhanced immunoturbidimetric method in Roche Cobas C501 analyzer. A Mann–WhitneyU-test was applied to compare the groups, a Mantel–Haenszel (log-rank) test was used to calculate for graphic of original individual patient time-to-event data, and a Kaplan–Meier survival curve was plotted.ResultsA ROC curve analysis identified a best predictive procalcitonin level cut-off point of 0.560 μg/L, with a specificity of 97% and sensitivity of 27% for CCHF. The highest levels of procalcitonin were measured on day 2 during the follow-up throughout and on the 5th day peaked for a second time, lower than the first.ConclusionsProcalcitonin may serve as prognostic indicator and an auxiliary biomarker to rule out of CCHF.

Abstract

Objectives
To demonstrate immature granulocyte (IG) count and delta neutrophil index (DNI) values (novel potential predictive marker for neonatal sepsis) for neonates.

Methods
This prospective controlled clinical study was consisted of 208 patients (77 in the study group and 131 in the control group) who were delivered between January 2016 and January 2018 at the Hacettepe University Neonatal Intensive Care Unit in Ankara, Turkey. In this study, we evaluated value of DNI in diagnosing neonatal sepsis by comparing the DNI values in culture positive septic neonates with healthy neonates.

Results
In our study, the median interquartile range (IQR = 25–75%) DNI was 0.1% (0.0–0.3%) in the control group and 1.5% (1.0–2.45%) in the sepsis group (p < 0.05). In our ROC curve analysis, the cut-off value for the DNI as a sepsis marker was 0.65%, with 96.2% specificity and 97.4% sensitivity. Those patients with gram-negative isolates had significantly higher DNI and IG counts when compared to those patients with gram-positive bacteria (p < 0.05).

Conclusions
Our findings indicated that the DNI counts are significant diagnostic biomarkers for neonatal sepsis. They may also have utility in determining the sepsis etiology (differentiating between gram-positive and gram-negative agents).
Telicity and object position in Taiwanese Southern Min and Hakka
Authors: Wang Chyan-an Arthur , Wu Hsiao-hung Iris 
Published: August 2020

AbstractThis paper investigates the phenomena of obligatory object preposing in Taiwanese Southern Min (TSM) and Hakka. We first refute the previous treatment of having the information-structural theory as an exclusive account of TSM and Hakka obligatory object preposing and show that telicity is another important dimension to object prespoing in the two languages. In particular, object preposing always takes place when a given verb bears a designated telicity marker, independent of the referential and information structural properties of its object. Consistent with recent work on the syntax of lexical aspect that telic readings are reflected in certain syntactic configurations, we suggest that in TSM and Hakka, telicity involves feature checking of the verb and its objects in the checking domain of a functional projection InAspP. For a theme argument to be able to measure out an event, it must enter an Agree relationship with the [telic] feature in InAsp, which has the edge property that triggers movement of the theme to its specifier. The proposed aspectual structure is further supported by distributional and interpretational properties including object preposing asymmetry, height of interpretation site of ambiguous adverbials, as well as the distribution of time-frame adjuncts and durative adjuncts.
Makrotypografie als Verständlichkeitsfaktor
Authors: Bock Bettina M. 
Published: August 2020

Abstract
Easy-to-read (ETR) German aims to reduce communication barriers by simplifying both language and content as much as possible. For that purpose, a rigid rule-based practice is commonly used. The main target group are usually people with intellectual disability (ID) but other groups, e. g. functional illiterates, are also often intended addressees. The comprehensibility of ETR German texts, however, still awaits systematic empirical testing. The aim of the present study is to investigate macrotypography as a factor of text comprehensibility across different text types. A sample of individuals with ID and functional illiterates participated in qualitative interviews and was given a multiple-choice procedure in which typical ETR macrotypography and conventional text type macrotypography were compared. The results showed an advantage of the conventional macrotypographic design. In one case the text type was almost as easily recognized when ETR macrotypography was used. The analysis of the qualitative data, however, showed that it was primarily the participants with ID who were able to recognise the text type in this case. The outcome of the study therefore argues that conventional macrotypography may be more advantageous than the macrotypographic practice associated with ETR German.

AbstractThe new samarium germanide SmGe3is obtained by high-pressure high-temperature synthesis of pre-reacted mixtures of samarium and germanium at a pressure of 9.5 GPa and temperatures between 1073 and 1273 K. SmGe3decomposes at 470(5) K into SmGe2,α-Sm3Ge5and a hitherto unknown phase. SmGe3exhibits a superstructure of the cubic Cu3Au-type. Transmission electron microscopy measurements of crystalline particles and prepared lamellae indicate a high density of defects on the nanoscale. Selected area electron diffraction and elaborate X-ray powder diffraction measurements consistently indicate a 2a0 × 2a0 × 2a0superstructure adopting space groupFm3¯m$Fm\overline{3}m$witha = 8.6719(2) Å.

Abstract
Exact force-free plasma equilibria satisfying the nonlinear Beltrami equation are derived. The construction is based on a nonlinear transformation that allows to get from any solution to the linear Beltrami equation a one-parametric family of exact solutions to the nonlinear one. Exact force-free plasma equilibria connected with the Sine-Gordon equation are presented.
The electronic structure, phase transition, elastic, thermodynamic, and thermoelectric properties of FeRh: high-temperature and high-pressure study

Published: August 2020

Abstract
Using the projector augmented wave (PAW) within the Perdew, Burke, and Ernzerhof (PBE) form of generalized gradient approximation (GGA), We present a study of the electronic structure, phase transition, elastic, thermodynamic, and thermoelectric properties of FeRh. We find that FM structure exhibits the largest Fe magnetic moment, which is in accordance with the experimental data and Fe magnetic moment for A-AFM and G-AFM phases, c-AFM, A’-AFM and Ort phases show lower Fe local magnetic moment. Our most stable structure is orthorhombic phase. This conclusion is supported by Zarkevich and Johnson, but contrary to the results of Aschauer et al., Kim et al. and Gruner et al. The obtained phase transition of Ort → c-AFM occurs at ca. 116.5 GPa and c-AFM to A’-AFM phase transition pressure is 119.0 GPa. The compressional, shear and average velocities as well as the bulk and shear moduli increase monotonically with increasing pressure. It is also found that thermal electronic contributions to specific heat are not negligible and contribution rate of electrons to the total thermal conductivity dominant at high temperature. At lower temperature, lattice thermal conductivity KL increases rapidly with the increasing pressure and KL has a moderate increase under pressure at higher temperature. Whereas, electronic thermal conductivity Ke is opposite. Most of the heat is carried by phonons with mean free paths ranging from 10 to 300 nm at 300 K.

Abstract
Worldwide water pollution is a serious issue, which needs special attention. Among these pollutants, methylene blue (MB) is dangerous for aquatic life as well as for human beings. Researchers are trying their best to degrade the various pollutants found in water. In the present work, we synthesized ZnO nanorods (NRDs) by one-step hydrothermal method. The synthesized samples were then characterized with the help of X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). ZnO nanostructures were composed of rod-shaped NRDs with flat edges and were highly crystalline with hexagonal shaped morphology. UV/Visible spectroscopy was carried out to investigate the optical properties, which shows the absorption in UV range and highly transmittance in the visible range. Finally, the photocatalytic activity was performed for the degradation of MB. The results show that MB was not fully degraded by bare ZnO NRDs. After all, we coated Ag NPs on the surfaces of ZnO NRDs through the simple solution-based method. The UV/Visible data reveal absorption in the UV as well as in the visible range due to the surface plasmonic effect of Ag NPs. Hybrid Ag-coated ZnO NRDs successfully degraded MB within 60 min. Therefore, we found that Ag-coated ZnO NRDs show good photocatalytic properties as compared to uncoated ZnO NRDs.
On the influence of water on urea condensation reactions: a theoretical study
Authors: Gratzfeld Dennis , Heitkämper Juliane , Debailleul Julien , Olzmann Matthias 
Published: August 2020

Abstract
The influence of water molecules on the kinetics of urea condensation reactions was studied with high-level quantum chemical methods and statistical rate theory. The study focuses on the production of biuret, triuret, and cyanuric acid from urea because of their relevance as unwanted byproducts in the urea-based selective catalytic reduction (urea-SCR) exhaust after treatment of Diesel engines. In order to characterize the potential energy surfaces and molecular reaction pathways, calculations with explicitly-correlated coupled-cluster methods were performed. It turned out that the reactions proceed via pre-reactive complexes and the inclusion of one or two water molecules into the condensation mechanisms leads to a decrease of the energy barriers. This effect is particularly pronounced in the production of biuret. Due to the pre-reactive equilibria, the rates of the overall reactions can increase or decrease by incorporating water into the mechanism, depending on the temperature and water concentration. Under the conditions of urea-SCR, the studied reactions are too slow to contribute to the observed byproduct formation.
A Genetic Screen Links the Disease-Associated Nab2 RNA-Binding Protein to the Planar Cell Polarity Pathway inDrosophila melanogaster

Published: August 2020

AbstractMutations in the gene encoding the ubiquitously expressed RNA-binding protein ZC3H14 result in a non-syndromic form of autosomal recessive intellectual disability in humans. Studies in Drosophila have defined roles for the ZC3H14 ortholog, Nab2 (aka Drosophila Nab2 or dNab2), in axon guidance and memory due in part to interaction with a second RNA-binding protein, the fly Fragile X homolog Fmr1, and coregulation of shared Nab2-Fmr1 target mRNAs. Despite these advances, neurodevelopmental mechanisms that underlie defective axonogenesis in Nab2 mutants remain undefined. Nab2 null phenotypes in the brain mushroom bodies (MBs) resemble defects caused by alleles that disrupt the planar cell polarity (PCP) pathway, which regulates planar orientation of static and motile cells via a non-canonical arm of the Wnt/Wg pathway. A kinked bristle phenotype in surviving Nab2 mutant adults additionally suggests a defect in F-actin polymerization and bundling, a PCP-regulated processes. To test for Nab2-PCP genetic interactions, a collection of PCP mutant alleles was screened for modification of a rough-eye phenotype produced by Nab2 overexpression in the eye (GMR&gt;Nab2) and, subsequently, for modification of a viability defect among Nab2 nulls. Multiple PCP alleles dominantly modify GMR&gt;Nab2 eye roughening and a subset rescue low survival and thoracic bristle kinking in Nab2 zygotic nulls. Collectively, these genetic interactions identify the PCP pathway as a potential target of the Nab2 RNA-binding protein in developing eye and wing tissues and suggest that altered PCP signaling could contribute to neurological defects that result from loss of Drosophila Nab2 or its vertebrate ortholog ZC3H14.
Age and Genetic Background Modify Hybrid Male Sterility in House Mice

Published: August 2020

Abstract
Hybrid male sterility (HMS) contributes to reproductive isolation commonly observed among house mouse (Mus musculus) subspecies, both in the wild and in laboratory crosses. Incompatibilities involving specific Prdm9 alleles and certain Chromosome (Chr) X genotypes are known determinants of fertility and HMS, and previous work in the field has demonstrated that genetic background modifies these two major loci. We constructed hybrids that have identical genotypes at Prdm9 and identical X chromosomes, but differ widely across the rest of the genome. In each case, we crossed female PWK/PhJ mice representative of the M. m. musculus subspecies to males from a classical inbred strain representative of M. m. domesticus: 129S1/SvImJ, A/J, C57BL/6J, or DBA/2J. We detected three distinct trajectories of fertility among the hybrids using breeding experiments. The PWK129S1 males were always infertile. PWKDBA2 males were fertile, despite their genotypes at the major HMS loci. We also observed age-dependent changes in fertility parameters across multiple genetic backgrounds. The PWKB6 and PWKAJ males were always infertile before 12 weeks and after 35 weeks. However, some PWKB6 and PWKAJ males were transiently fertile between 12 and 35 weeks. This observation could resolve previous contradictory reports about the fertility of PWKB6. Taken together, these results point to multiple segregating HMS modifier alleles, some of which have age-related modes of action. The ultimate identification of these alleles and their age-related mechanisms will advance understanding both of the genetic architecture of HMS and of how reproductive barriers are maintained between house mouse subspecies.
Der „einflusslos Konzertierende“ als Problemkonstellation des acting in concert gem. § 30 Abs. 2 WpÜG
Authors: Gansmeier Johannes 
Published: August 2020

Zusammenfassung
Eine Zurechnung von Stimmrechten Dritter wird im Kapitalmarktrecht – zur Vermeidung von Umgehungen – in unterschiedlichen Regelungskomplexen angeordnet (vgl. § 34 WpHG, § 30 WpÜG). Von hervorgehobener Bedeutung ist dabei die Zurechnung unter dem Gesichtspunkt des sog. acting in concert gem. § 30 Abs. 2 WpÜG. Hiervon hängt in vielen Fällen maßgeblich ab, ob eine – zeit- und kostenintensive – Angebotspflicht der Konzertierenden nach § 35 Abs. 2 WpÜG begründet wird oder nicht. Besondere Schwierigkeiten bereitet die Konstellation „struktureller Dominanz“ innerhalb eines Abstimmungspools: Hier steht in Frage, ob sich die Stimmrechtszurechnung auch auf einen „einflusslos Konzertierenden“ erstrecken soll. Der vorliegende Beitrag zielt auf eine Problemlösung entlang einer näheren Analyse des Telos von § 30 Abs. 2 WpÜG. Darauf aufbauend wird für Konstellationen „struktureller Dominanz“ in Stimmrechtskoordinierungen ein neuer Ansatz entwickelt, der für den „Einflusslosen“ zwingend die Konzertierungsauflösung vorsieht, möchte dieser einer Angebotspflicht entgehen.

Abstract
This paper examines circuit breakers (CBs), i. e. emergency systems of trading venues that interrupt or restrain trading when significant price movements of financial instruments occur. After a description of the ratio legis and the economic fundamentals, the genesis and the different forms of CBs are presented. The European legal framework is then outlined. The relevant rules of the Frankfurt Stock Exchange (FWB) serve as an example.

Published: August 2020

The article deals with the personal qualities of the tenth grade pupils which are perceived as the disturbances and the stimulus of educational interaction by physical education teachers in physical education classes.
Research results have shown that all physical education teachers participating in the study (both men and women) are positive about three personal qualities of pupils: curiosity, self-confidence and initiative. According to the respondents, those qualities mentioned above help develop pedagogical interaction in physical education activities. Physical education teachers (women) distinguish the following less favorable personal qualities of pupils as anger, hypocrisy, revengefulness and avoidance of responsibility, whereas men more often indicate only one quality interfering with pedagogical interaction – poor physical health. In general, all physical education teachers agree about such pupils’ qualities as indifference and laziness as the sources of disturbances in the educational interaction. Besides, poor teaching / learning environment in physical education classes is one of the main reasons of unconstructive pedagogical interaction according to the respondents.

La presente investigación es de tipo aplicativo – experimental cuyo objetivo fue diseñar una cámara electrónica de esterilización UV para equipos de protección médica contra el COVID19. Este equipo biomédico posee un control PID que se ejecuta por medio de la aplicación de la programación digital para el control de la lámpara UV que emiten radiación Ultra Violeta de tipo C. Dentro del diseño de control de potencia para la activación de la lámpara de esterilización UV, se considera un pulso proporcionado por la placa de desarrollo Arduino Nano, como resultado del diseño del controlador PID de la etapa precedente que activa un optoacoplador MOC3031 compuesto por un diodo emisor de luz y un triac que permite la habilitación de cargas con voltaje pico de 250 a 400V, por lo que son muy adecuadas para la activación de la lámpara de radiación UV-C. También presenta un control de cierre que brinda seguridad al usuario para que la luz UV no le genere lesiones. Los resultados que se obtuvieron fueron eficaces puesto que el empleo de luz ultravioleta tipo C, altera la composición de los ácidos nucleicos, rompiendo los enlaces de ADN y ARN de los virus, bacterias y microorganismos primitivos, por causa de la exposición de radiación con una longitud de onda pico de 254nm. Esta ruptura en el material del ADN o ARN evita que el microorganismo pueda replicarse. Es por ello que muestra una eficacia para la desinfección y esterilización de equipos de protección personal médica (mascarillas, mandiles entre otros) de profesionales de la salud.
