Heterotopien des Feierns
Authors: Hoder Manuel 
Published: February 2020

Abstract
In so far as Arthurian narrative can be considered to be a utopian project, it converges in the festival motif at the Arthurian court. However, the festival ideal in particular is in danger of losing grip on reality as the process of literalizing Arthurian Romances advances. In this context the final festivities in the Arthurian Romances of the Pleier serve as a mediating principle. By connecting the leitmotifs of the histoire with his depiction of festivity scenes, the Pleier conceptualizes them as a space in which courtly norms are negotiated in a lively fashion. The festival scenes thus serve as venues for representation and reflection, thereby becoming ›heterotopias of celebrating‹.
Vulnerabilitätsmetaphern und Narrativierungsstrategien in den ›Offenbarungen‹ und der ›Vita‹ Elsbeths von Oye
Authors: Müller Mareike von 
Published: February 2020

Abstract
Due to highly unstructured, redundant, and ambiguous descriptions of bloody self-flagellations by the writing self, the ›revelations‹ of Elsbeth von Oye present themselves as a challenge for research. Elsbeth’s ›vita‹ however seeks to eliminate those bewildering elements and repositions many textual passages. Considering both texts, this article examines the approaches for narrative transformation as well as the deliberate refusal of making narrative sense. While the reorganization of the material in the ›vita‹ has a strong impact on the creation of a narrative sense, the ›revelations‹ seem to purposely decline narrative patterns to build a concept of holiness, which orientates towards legendary texts.
Estimation of the total antioxidant potential in the meat samples using thin-layer chromatography
Authors: Piszcz Paweł , Tomaszewska Magdalena , Głód Bronisław K. 
Published: February 2020

AbstractThere is limited literature on the antioxidative properties of food of animal origin. Measurements of antioxidative properties are usually performed using the reaction of reduction of colored 2,2-diphenyl-1-picrylhydrazyl (DPPH) radials. Changes of the DPPH color are tracked photometrically. These measurements are interfered by both, the tested samples and reduced DPPH. This study aims to demonstrate the ability to separate different forms of DPPH (DPPH•and DPPH-H) by thin-layer chromatography (TLC). Further, it has been practically applied in the study of the determination of antioxidative properties of the meat samples. It was found that TLC can be used for the separation of different forms of DPPH as well as for measurement of TAP (total antioxidant potential) values related to the DPPH•. The strongest antioxidant properties were observed for pork neck extracted in buffer pH 2 and for smoked salmon fish extracted in acetone, the lowest for veal and turkey fillet extracted in methanol.

Evaluation of corrosion inhibition and adsorption behavior of Thymuszygis subsp. gracilis volatile compounds on mild steel surface in 1 m HCl
Authors: Ouknin Mohamed , Romane Abderrahmane , Ponthiaux Jean-Pierre , Costa Jean , Majidi Lhou 
Published: February 2020

AbstractThe inhibition effect ofThymus zygissubsp.gracilis(TZ) on mild steel corrosion in 1mhydrochloric acid has been investigated by weight loss measurements, surface analysis [scanning electron microscopy (SEM)-energy-dispersive X-ray (EDX), three-dimensional (3D) profilometry, and Fourier transform infrared analysis], potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS). Gravimetric results indicate that TZ exhibits good inhibition efficiency of 80.40% attained at 3 g/l. Polarization measurements show that the studied inhibitor is a mixed type. EIS measurements revealed that the charge transfer resistance increases with increasing concentration of TZ, which suggests a Langmuir adsorption isotherm model. Based on SEM-EDX and 3D profilometry, it appears that the surface is remarkably improved in the presence of TZ oil compared to that exposed to the acid medium without TZ oil. From the obtained results, it can be concluded that this oil is a new natural substance that can be used against material corrosion in aggressive medium.
Hepatocellular carcinoma in the context of non-alcoholic steatohepatitis (NASH): recent advances in the pathogenic mechanisms
Authors: Lequoy Marie , Gigante Elia , Couty Jean-Pierre , Desbois-Mouthon Christèle 
Published: February 2020

Abstract
Hepatocellular carcinoma (HCC) is the most common type of liver cancer. HCC is particularly aggressive and is one of the leading causes of cancer mortality. In recent decades, the epidemiological landscape of HCC has undergone significant changes. While chronic viral hepatitis and excessive alcohol consumption have long been identified as the main risk factors for HCC, non-alcoholic steatohepatitis (NASH), paralleling the worldwide epidemic of obesity and type 2 diabetes, has become a growing cause of HCC in the US and Europe. Here, we review the recent advances in epidemiological, genetic, epigenetic and pathogenic mechanisms as well as experimental mouse models that have improved the understanding of NASH progression toward HCC. We also discuss the clinical management of patients with NASH-related HCC and possible therapeutic approaches.

Published: February 2020

Abstract

Background
The increase in soluble suppression of tumorigenicity 2 (sST2) both in the diagnosis and prognosis of heart failure is well established; however, existing data regarding sST2 values as the prognostic marker after myocardial infarction (MI) are limited and have been conflicting. This study aimed to assess the clinical significance of sST2 in predicting 1-year adverse cardiovascular (CV) events in MI patients.

Materials and methods
In this prospective study, 380 MI patients were included. Participants were grouped into low sST2 (n = 264, mean age: 60.0 ± 12.1 years) and high sST2 groups (n = 116, mean age: 60.5 ± 11.6 years), and all study populations were followed up for major adverse cardiovascular events (MACE) which are composed of CV mortality, target vessel revascularization (TVR), non-fatal reinfarction, stroke and heart failure.

Results
During a 12-month follow-up, 68 (17.8%) patients had MACE. CV mortality and heart failure were significantly higher in the high sST2 group compared to the low sST2 group (15.5% vs. 4.9%, p = 0.001 and 8.6% vs. 3.4% p = 0.032, respectively). Multivariate Cox regression analysis concluded that high serum sST2 independently predicted 1-year CV mortality [hazard ratio (HR) 2.263, 95% confidence interval (CI) 1.124–4.557, p = 0.022)]. Besides, older age, Killip class >1, left anterior descending (LAD) as the culprit artery and lower systolic blood pressure were the other independent risk factors for 1-year CV mortality.

Conclusions
High sST2 levels are an important predictor of MACE, including CV mortality and heart failure in a 1-year follow-up period in MI patients.
Preparation of WC-TiC-Ni3Al-CaF2 functionally graded self-lubricating tool material by microwave sintering and its cutting performance

Published: February 2020

AbstractWith the concern of the environment, green dry cutting technology is getting more and more attention and self-lubricating tool technology plays an important role in dry cutting. Due to the demand for high temperature performance of tools during dry cutting process, cemented carbide with Ni3Al as the binder phase has received extensive attention due to its excellent high temperature strength and high temperature oxidation resistance. In this paper, WC-TiC-Ni3Al-CaF2graded self-lubricating material and tools were prepared by microwave heating method, and its microstructure, mechanical properties and cutting performance were studied. Results show that gradient self-lubricating material can be quickly prepared by microwave heating technology, and the strength is equivalent to that of conventional heating technology. CaF2not only plays a role in self-lubrication, but also refines the grain of the material. A reasonable gradient design can improve the mechanical properties of the material. When the gradient distribution exponent is n1= 2, the material has high mechanical properties. Cutting experiments show that the WC-TiC-Ni3Al-CaF2functional gradient self-lubricating tool has better cutting performance than the homogeneous WC-TiC-Ni3Al hard alloys.
Microstructure, phase composition and oxidation behavior of porous Ti-Si-Mo intermetallic compounds fabricated by reactive synthesis
Authors: Ru Jinming , Wang Ya , Wang Yuemei , Xu Xiaojing 
Published: February 2020

AbstractPorous Ti-Si-Mo intermetallic compounds were fabricated by reactive synthesis using C7H10N2O2S as a foaming agent. The effects of Mo content on the microstructure, phase composition and oxidation behavior were investigated. The results show that the porosity and the fractal dimension decreases and then increases as the Mo content increases. It is found that the pore size is mainly distributed in less than 1μm. The phase compositions mainly consist of TiSi, Ti5Si4, Mo5Si3 and TiO, and the Ti5Si3 phase is detected at Mo content of 16 wt.% in particular. In addition, the mass gain of the oxidized samples gradually decreases as the Mo content increases. It is concluded that the oxidation resistance at high-temperature generally decreases as the fractal dimension increases. It is suggested that porous Ti-Si-Mo intermetallic compounds have potential applications in sound absorption and heat dissipation at high-temperature.
Numerical Simulation of A Cubic Spout-Fluid Bed: Influences of Inlet Gas Temperature and Jet to Bed Cross-Section Ratio

Published: February 2020

AbstractIn this paper, we study the role of inlet gas temperature and jet to bed cross-section ratio on hydrodynamics and circulation patterns of particles in a spout-fluid bed. The system is modeled using CFD-TFM approach based on Eulerian-Eulerian method. Simulation results are validated by experimental data measured by (Link 2008. “PEPT and Discrete Particle Simulation Study of Spout-fluid Bed Regimes.”Aiche Journal54 (5): 1189–202). First, the sensitivity analysis of simulation results versus the most significant parameters are conducted to find the optimum values for each parameter. Subsequently, the role of inlet gas temperature and cross-section ratios are studied in detail. The simulation results clearly demonstrate that increasing the inlet gas temperature raises particles’ velocity in the bed and affects the circulation pattern in annulus region. Additionally, it is shown that higher gas temperature leads to existence of hot spots in the annulus region. In case of jet to bed cross-section ratio, using larger ratios results in higher velocities and lower pressure drop along the bed.

Published: February 2020

Abstract
Women represent the majority of medical students in several countries. In any surgical specialty and above all in surgical leadership positions, women still remain disproportionally underrepresented. The objective of this study was to investigate female surgeons’ career advancement and satisfaction with training. A standardized questionnaire was devised and sent out via the web-based survey tool SurveyMonkey® to female surgeons in the German federal state of North Rhine-Westphalia. A total of 125 completed questionnaires were analyzed (response rate 40.8%). Female surgeons are at least largely (76%) satisfied with their surgical training. Increased time (>5 h/week) as the principal surgeon in the operating room significantly stimulates the satisfaction with the surgical training (86% vs. 68%, p = 0.0384). At the participants’ current workplace, the heads of departments are predominantly male surgeons (91%). Respondents not satisfied with their surgical training prefer a female head of department more frequently (24% vs. 2%, p = 0.0085). The majority of the respondents themselves aspire to become a consultant surgeon (56%), while only 12% intend to become a head of a department. Female surgeons aiming at leadership positions work overtime (≥50 h/week) significantly more frequently (81% vs. 57%, p = 0.0041). Favoritism of male colleagues is perceived by 34%. Respondents who do not perceive any preferential treatment are significantly more satisfied with their surgical training (88% vs. 57%, p = 0.0004). In conclusion, female surgeons seem positive about their career choice, once in the surgical profession, and aptly fill upcoming positions. Women interested in surgery are likely to pursue a surgical career despite the alleged workload, demonstrating the importance of professional self-fulfillment among female surgeons.
Partially error-affected point-wise weighted closed-form solution to the similarity transformation and its variants
Authors: Ligas Marcin 
Published: February 2020

Abstract
The paper presents a closed-form solution to the point-wise weighted similarity transformation and its variants in the least squares framework under two estimation scenarios.
In the first scenario a target system is subject to random errors whilst in the second one a source system is considered to be erroneous. These transformation models will be named asymmetric in contrast to the symmetrical one solved under the errors-in-variables model where both systems are contaminated by random errors. The entire derivation is based on Procrustes Analysis. The formulas presented herein hold for both 2D and 3D transformations without any modification. The solution uses a polar decomposition to recover the rotation matrix.
Autoimmune polyglandular syndrome type II with co-manifestation of Addison’s and Graves’ disease in a 15-year-old boy: case report and literature review
Authors: Schulz Lena , Hammer Elke 
Published: February 2020

AbstractBackgroundAutoimmune polyglandular syndrome type II (APS II) is defined as the combination of autoimmune adrenal insufficiency and autoimmune thyroid disease (AITD) and/or type I diabetes mellitus (T1DM) in the same patient.Case presentationA 15-year-old boy had a history of weight loss, nausea and vomiting, headache, restlessness, and tanned skin. He was diagnosed with Graves’ disease. Two weeks after carbimazol therapy was commenced, he presented with adrenal crises (fever, arterial hypotension, hyponatremia, adrenocorticotropic hormone [ACTH] 1119.6 ng/mL [normal range <60] and low cortisol). He received hydrocortisone and fludrocortisone, and improved quickly. Thyroid-stimulating hormone (TSH) receptor autoantibodies as well as 21-hydroxylase antibodies were elevated.ConclusionsAlthough the combination of Graves’ and Addison’s disease is extremely rare, especially in children, it is critical to make the diagnosis. Accelerated metabolic rate increased the risk for adrenal crises in our patient. This case contributes to the spectrum of APS II and its manifestation.
Burnout in neonatal intensive care unit nurses: relationships with moral distress, adult attachment insecurities, and proneness to guilt and shame
Authors: Barr Peter 
Published: February 2020

AbstractBackgroundInformed by the person-environment transactional model of stress, the purpose of the study was to explore the relationships of environment-related moral distress and person-related anxious and avoidant adult attachment insecurities, and personality proneness to guilt and shame with burnout in neonatal intensive care unit (NICU) nurses.MethodsThis was a multicenter cross-sectional self-report questionnaire cohort study comprising 142 NICU nurses currently working on six Level 3–4 NICUs in New South Wales, Australia.ResultsBurnout was reported by 37% of NICU nurses. Moral distress, anxious and avoidant attachment, and guilt- and shame-proneness had moderate-large zero-order correlations with burnout. Overall, these predictor variables explained 40% of the variance in burnout. Moral distress (β = 0.40, P < 0.001), anxious attachment (β = 0.18, P < 0.05) and shame-proneness (β = 0.22, P < 0.01) were unique predictors of burnout. Shame-proneness partially mediated the effect of anxious attachment on burnout [indirect effect,B = 0.12, confidence interval (CI) (0.051–0.201)].ConclusionThe management of burnout in NICU nurses requires attention not only to environment-related moral distress but also to person-related anxious and avoidant adult attachment insecurities and personality proneness to guilt and shame.

Published: February 2020

Abstract

Background and aim
To explore the diagnostic value of recombinant heparin-binding hemagglutinin adhesin (HBHA) protein antigen in spinal tuberculosis.

Materials and methods
Forty patients with spinal tuberculosis were included in the experimental group and 40 healthy people were included in the control group. Serum IgG antibody expression level was detected with recombinant HBHA protein as the antigen, using enzyme-linked immunosorbent assay (ELISA) detection.

Results
Patients with spinal tuberculosis and healthy volunteers were included in this study. A total of 40 eligible patients with spinal tuberculosis were included (24 males and 16 females, aged 18-72 years, with an average age of 41.24 ± 15.74 years). Forty healthy people were included (21 males and 19 females, aged 18-70 years, with an average age of 41.33 ± 12.36 years). On comparing the groups, no significant difference was found in the general data (P >0.05). IgG antibody level in the experimental group was higher than that in the control group, and the difference was significant (P < 0.00001).

Conclusions
Detection of serum HBHA protein antibody is of great value in the auxiliary diagnosis of spinal tuberculosis, and high HBHA expression can be used as an indicator for diagnosis of spinal tuberculosis.
Verb placement and accentuation: Does prosody constrain the Estonian V2?
Authors: Sahkai Heete , Tamm Anne 
Published: February 2020

Abstract
The paper contributes to the understanding of the variation in finite verb placement in Estonian, a verb-second language, by establishing two descriptive facts. First, it identifies a previously undescribed finite verb position in Estonian declarative main clauses, which will be referred to as ‘clause-medial’. The clause-medial position is located between clause-medial sentence adverbials on the one hand, and VP adverbials and the complements of the verb on the other hand. Secondly, the paper reports two empirical studies providing evidence in support of the hypothesis that the occurrence of a finite verb in the proposed clause-medial position, as opposed to its occurrence in the second position, correlates with its accentuation. While clause-medial verbs tend to bear a nuclear pitch accent, second-position verbs don’t. Finally, the paper briefly discusses some broader implications of the existence of the clause-medial finite verb position and of the interaction between verb placement and prosody.
Can God Promise Us a New Past? A Response to Lebens and Goldschmidt
Authors: Faul Bogdan V. 
Published: February 2020

AbstractSamuel Lebens and Tyron Goldschmidt provided original theodicies, which suggest that at one time God will change the past, either by erasing/substituting the sins of humans or erasing the whole entirety of evils. Both theodicies imply the idea that God can completely change the past without leaving any traces. In this paper, I argue that Lebens’ and Goldschmidt’s preferred model, which they call the scene-changing theory, is problematic. First, its complex metaphysical foundation could be replaced with presentism (roughly, the view in the ontology of time that only present things exist) without losing any substantial heuristics. Second, their theory either implies a controversial theory of truthmaking under presentistic and hyper-presentistic ontology or implies controversial views on the counting of events under presentistic and hyper-presentistic ontology. Thirdly, I will argue that any theory of elimination/substitution of evils of the past implies that there are unnecessary evils, which is inconsistent with God’s goodness.

Published: February 2020

AbstractMetal-organic frameworks (MOFs) are promising sacrificial templates for synthesis of carbon functional materials with a relatively high concentration of stabilized metallic species. In this work coordination polymers based ontrans,trans-muconic acid and transition metals (Cu, Zn, Ni, Co) were prepared and selected as the precursors for supramolecular organization of nanocomposites. The coordination polymers and metal-containing thermolysis products obtained were characterized using a number of analytical techniques including powder X-ray diffraction, elemental analysis, thermal gravimetric analysis, scanning electron microscopy and volumetric nitrogen adsorption/desorption. This study extends the application of coordination polymers as precursors for designing of carbon materials incorporating metal nanoparticles. It is shown that appropriate choice of metal-organic precursors in solid-phase thermolysis allowed to get materials with determined morphologies.

Abstract
The 50Cr(n,2n)49Cr, 52Cr(n,2n)51Cr, 52Cr(n,p)52V, 55Mn(n,2n)54Mn, 55Mn(n,α)52V and 55Mn(n,γ)56Mn reaction cross sections at the neutron energy of 14.54 ± 0.24 MeV were measured by using activation method along with off-line γ-ray spectrometry. The 27Al(n,p)27Mg monitor reaction was used for the 52Cr(n,p)52V and 55Mn(n,α)52V reactions, whereas the 197Au(n,γ)198Au monitor reaction for the 55Mn(n,γ)56Mn reaction. The 27Al(n,α)24Na monitor reaction was used for other three reactions. The neutron beam was generated from the T(d,n)4He reaction using the Purnima neutron generator at BARC, Mumbai. The covariance analysis for the uncertainties of reaction cross sections was performed by considering the correlations between different attributes. The present results were compared with the literature data, evaluated data of ENDF, ROSFOND, CENDL, JENDL and JEFF libraries as well as with the theoretical values based on TALYS-1.9 calculation.
