Vom Artushof zum Palast der Saelde : Heldenreise und Raumkonzeption in der „Crône“ Heinrichs von dem Türlin
Authors: Adams Klara
Published: December 2022

Die vorliegende Untersuchung befasst sich mit dem späten Artusroman „Diu Crône“. Grundlage der Analyse sind die Struktur der Heldenreise nach Josef CAMPBELL und die räumliche Konzeption von HEINRICHs Werk. Beide Ansatzpunkte verknüpfend wird deutlich, dass der bizarre und befremdlich anmutende Weg, den Gawein absolviert, einen entscheidenden liminalen Lebensabschnitt für den Artusritter darstellt. Im Laufe der Reise muss der Protagonist sich Station für Station die vielschichtige Welt der Crône erschließen, Schwellen passieren, um in andere Reiche vorzudringen, und entsprechend seinem Verhalten vor Ort können die Strukturen der Räume modifiziert werden. Die Reise fordert gleichermaßen, dass Gawein sich von bestehenden, vertrauten Handlungsmuster löst und bereit ist, sein Handlungsrepertoire zu erweitern bzw. zu verändern, um damit sowohl der Anderswelt als auch dem höfischen Raum gerecht zu werden. Auf Grundlage der großen Varianz der geographischen Gegebenheiten in der Crône bereitet HEINRICH durch die Schilderung des Werdegangs von Gawein so letztlich die Krönung des Ritters vor, die gleichermaßen das arthurische Reich wie auch die Präsenz des arthurischen Mythos über die Lebzeiten des Königs hinaus sichern soll – und damit das Weiterleben des Artusromans.

quelle gouvernance pour la restauration des rivières ?
Authors: ZINGRAFF-HAMED Aude
Published: December 2022

Dans le contexte de l'augmentation des besoins en énergie renouvelable pour lutter contre les moteurs du changement climatique, de l'émergence de la conscience écologique, de l'augmentation des risques d'inondation dus aux changements climatiques, et de la crise écologique, la gestion des rivières n'a jamais été aussi tendue entre des objectifs contradictoires. Pour s'adapter à ces changements environnementaux et sociétaux, des stratégies de gestion durable doivent être mises en œuvre. Quelle gouvernance de la rivière peut apporter les solutions au challenge du 21ème siècle ? Cette contribution synthétise et présente les résultats de nombreux travaux de recherche sur l’institutionnalisation de la restauration de rivière. Cette étude va au-delà de l'approche théorique et s'appuie sur l’observation de cas déjà réalisés tels que la restauration de l’Isar. Elle montre la complexité des projets de restauration considérant ses objectifs variés, la constellation des institutions concernées et le jeu des acteurs locaux. La discussion met en avant les moteurs et mécanismes décisifs pour une gestion résiliente de la rivière. Plus particulièrement la gouvernance polycentrique et la planification participative sont montrées comme facteurs de succès.
Représentations des digues de protection des marais côtiers atlantiques : regards mêlés arts et sciences

Published: December 2022

Dans un contexte d’élévation du niveau de la mer, les rapports entre les humains et les littoraux sont étudiés via la place jouée par les digues à l’aide d’une approche sensible et cognitive. La collecte des matériaux artistiques et scientifiques s’est concentrée sur trois marais côtiers de Charente-Maritime : le marais du Fier d'Ars (Île de Ré), le marais de Tasdon (Ville de La Rochelle) et le marais de Moëze-Brouage (au sud de Rochefort). La représentation des digues est au cœur de l’œuvre artistico-scientifique en permettant d’observer autrement la place que l’homme laisse à la nature dans ses aménagements. En effet, les digues illustrent notre relation au monde, saisie avec ses forces et ses faiblesses : élever des murs pour se protéger des submersions marines ou laisser revenir la nature en laissant s’effondrer les murs. Ces investigations ont été enrichies par une réflexion en termes d’éthique environnementale. Les relations à la nature et les représentations qui leur sont associées orientent les discours comme les actions, les décisions de protection ou de conservation des éléments naturels jugés sensibles, voire irremplaçables. Cette perspective conduit également à s’interroger sur les dimensions spatiale et temporelle qui façonnent les marais, qui les délimitent et qui les bordent en élevant des frontières physiques avec des digues.

Published: December 2022

Breastfeeding mothers have limited access to healthcare facilities during the pandemic, thus raising their risk of psychological stress. This study aimed to analyze the correlation between psychological stress with breastfeeding frequency and breastmilk volume. A cross-sectional survey was conducted with 120 exclusively breastfeeding mothers. The Perceived Stress Scale (PSS) was employed as a stress assessment indicator measuring tool. The measurement of breastmilk volume was performed using a manual breast pump two hours before or after the baby suckles to restore milk production. The frequency of breastfeeding was calculated by adding up the number of times the baby is breastfed in a day. The chi-square test was used in this study. It was found that 68 respondents (56.7%) reported experiencing mild to moderate stress. Stress levels were found to have a significant connection with breastfeeding frequency and breastmilk volume (p < 0.05). The respondents who experienced severe stress have a 2.63-times higher risk for breastfeeding <8 times/day and 33.2 times higher risk of producing breast milk <100cc than respondents who experienced mild-moderate stress. Concerns about the psychological stress of breastfeeding mothers highlight the critical need for good mental health and broader help from families during the pandemic.

Growth performance, survival rate, productivity, and carcass analysis were examined in the whole grow-out production system for Pacific white shrimp Litopenaeus vannamei fed four commercial diets over 15 weeks. Shrimp were held in twelve hapas nets with a size of 2 x 2 x 1 m and installed within the commercial ponds. The shrimp were stocked with the density of 100 shrimp m-2 per net in a completely randomized design (CRD). All feed used in this study was characterized with high protein levels within the range of 40 â€“ 42% labeled as HP A and B; and medium protein levels (30 â€“ 35%), labeled as MP A and B. Based on the proximate and nutritional profile analysis of the diet, the nutritional profile of HP B, MP A and MP B written on the feed bags showed an inconsistent results compared to the results of the test.Â  Shrimp fed the highest protein level had higher final body weight; feed conversion ratio, thermal growth coefficient, survival rate and average daily growth compared to MP B. Shrimp fed higher protein level also exhibited the lowest feed conversion ratio compared to the group of shrimp fed with medium protein. The results obtained in this study indicated that with small difference in growth rates, especially between HP groups compared with MP A, there is still a chance to re-formulate the diet to produce a cost-effective diet that still fulfill the specific nutrient requirement of the shrimp. Feed did not influence the nutritional deposition of the whole body of shrimp, but it seemed due to the inappropriate drying techniquesÂ Keywords: Protein level, growth, carcass, Litopenaeus vannamei, specific nutrient

Published: December 2022

The size composition, growth pattern and condition factor of One thousand, two hundred and sixty (1260) mangrove oyster - Crassostrea tulipa (C. tulipa) from the mangrove swamp, Lagos Lagoon were studied using recommended morphometric methods. The total shell length ranged from 1.5cm to 18.4cm, maximum width ranged from 1.5cm â€“ 10.4cm and the total weight was between 1.92g â€“ 132.1g. The oysters showed a unimodal size distribution. Also, there is strong significant correlation between the shell total length and the total flesh weight suggesting that an increase in length gives a corresponding increase in weight of an individual oyster. The total length-total weight and total weight-flesh weight relationships were positively correlated with calculated â€œbâ€ of 0.5826 and 0.5887 for combined sexes respectively. Negative allometric growth observed was verified from the b < 3 value. The condition factor of the oysters ranged between 6.5 and 10.5 for both male and female species indicating that the species are in good condition despite reported contaminations of the lagoon water.Keywords: Bivalve, C. tulipa, Lagos Lagoon, length-weight.

Published: December 2022

The investigation on traditional salt production had developed in the characterization of Bittern. Bittern is the dense residual liquor with specific gravity â‰¥ 1.28 gr/cm3 obtained after precipitation and harvesting of NaCl salt from seawater. In this research, the measurment of sulfate in the bittern was carried out. Sulfate is one of the raw materials for MgSO4. The determination of sulfate concentration is using a turbidimetric method according to SNI 6989 20:2009 using a spectrophotometer at a wavelength of 420 nm.Â  In this process the Sulfate in an acidic environment reacts with barium chloride (BaCl2) to form barium sulfate (BaSO4) crystals. The light absorbed by the barium sulfate suspension is measured with a photometer and the sulfate content is calculated by comparing the readings with the calibration curve. The results of the analysis showed that at 31o Baume the sulfate content is 40.0 g/L, at 32o Baume the sulfate content is 42.6 g/L, at 33o Baume the sulfate content is 42.8 g/L. The sulfate concentration in the bittern showed a linear increase with increasing water concentration. The sulphate content of bittern with 31oBe levels has an average value of 40.028 g/L, at 32oBe levels the average sulphate content is 42.599 g/L and at 33oBe levels it is 42,825 g/L.Â Keywords: Bittern, Sulfate, oBe
“An Die Hoffnung”, and Beethoven’s use of Key Characteristics
Authors: Crawford Emily E.
Published: December 2022

What would compel a composer to set the same poem twice? Ludwig van Beethoven first set the text of Christoph Tiedge’s “An Die Hoffnung” (to Hope) between 1804 and 1805, and would later set the poem again, using even more of the text in 1815. While seeking context clues from what is known of his biography is crucial, another avenue of study lies within the pieces themselves. Through the study of key characteristics during Beethoven’s lifetime in addition to what biographical information we know, we can infer Beethoven’s intentions with each setting of the text and how this reflects his changing relationship to the text of “An Die Hoffnung”.
Data-Driven Assessment on the Brazilian Regulatory Framework for Biodiversity Access and Benefit Sharing (ABS)
Authors: Jungmann Diana , Avila Jorge de P.C.
Published: December 2022

This study presents a detailed assessment on the impact of the Brazilian legal framework related to the access and benefit sharing provisions of the UN Convention on Biological Diversity. The research is based on a comprehensive dataset that was systematically collected over several years, directly from the official government bodies responsible for its implementation. The aim of the study is to contribute to a fact-based discussion on the effectiveness of national ABS laws, focusing on the Brazilian legal framework, first established in the year 2000 and revised in 2015, as a case example. This study balances the costs and benefits of the Brazilian ABS system and assesses the regulatory challenges it poses to individuals, companies, and institutions that perform research, share knowledge, develop, manufacture or market products derived from Brazilian biodiversity. The study indicates that, after over 22 years of operation, the regulatory challenges are still real and relevant, and that the significant volume of data collected from users on access, prior commercialization and shipment of genetic materials abroad was never systematically assessed by the agencies in charge. Besides, it shows that the costs incurred by the government in managing the policy itself have been higher than the economic benefits it has made possible, and that the institutional mechanisms in place since 2015 have not been able to allocate the monetary benefits contributed by users to the National Benefit Sharing Fund to any projects aimed at developing sustainable uses or preserving Brazilian biodiversity.

Published: December 2022

The capability of radially polymerized bio-dendrimers and hyperbranched polymers for medical applications is well established. Among them, perhaps the most important are those that involve interactions with the regenerative mechanisms of cells. Dendritic polymers due to their distinctive architecture may play a multitude of roles such as protein biomimicry (collagen, elastin, hydroxy apatite production), gene and drug delivery (cell differentiation, antimicrobial protection), surface chemistry and charge modulation (adhesion to cells and tissues), polymer cross-linking (eye, skin and internal organ wound healing). The review highlights all the different categories of hard and soft tissues that may be remediated with their contribution. The reader will be also exposed to the incorporation methods to established biomaterials such as scaffolds, the functionalization strategies, and the synthetic paths for the assembly from biocompatible building blocks and natural metabolites.
The Infierno Glacier (Pyrenees, Aragon, Spain): evolution 2016-2022
Authors: Cancer Pomar Luis Antonio
Published: December 2022

The Infierno glacier is located in Aragon (Spain), Pyrenees mountain range, southern slope, the only one in this country that still preserves white glaciers. These are the southernmost glaciers in Europe and are currently in rapid regression. The work analyzes the evolution of the glacier between 2016 and 2022 (taking as "year zero" or starting point, 2015). In addition to the observations on the glacier itself, the variables (precipitation, temperatures, snow volumes and thicknesses) that allow understanding this evolution are studied. The results offer strong regression, with thickness losses in that period of 4.6 m and retreat of its front of 14.9 m. The evolution has frequent trend changes, linked to the interannual climatic irregularity characteristic of this mountain range. The main explanatory factor is the thermal increase. The thermal anomalies with respect to the average reference values have increased, in this period, +0.55° C. The year 2022 has been particularly warm and has recorded the greatest regression of the glacier (between May and August, the thermal anomalies were between +4° C and +2° C). Regarding precipitations, they have irregular tendencies and show a decreasing trend (-9% in the same period of time).
TRANSESTERIFICATION OF TRIGLYCERIDES WITH PROPAN-2-OL CATALYSED BY SULFURIC ACID
Authors: Melnyk Yurii , Melnyk Stepan , Mahorivska Halyna
Published: December 2022

Transesterification of sunflower oil triglycerides with propan-2-ol catalyzed by sulfuric acid has been studied. The effect of the homogeneous acid catalyst content and the triglycerides of sunflower oil : propan-2-ol molar ratio on the reagents conversion, selectivity of diisopropyl ether formation, the acid number and the color of reactions products on the iodine scale was determined. It was established that an increase in the sulfuric acid content from 1 wt. % up to 3 wt. % leads to a slight increase in the triglycerides conversion and a significant increase in the propan-2-ol conversion. A further increase in the acid catalyst content causes a decrease in the conversion of both triglycerides and alcohol. Comparison of the obtained results with the data on the reaction products composition allowed us to conclude that a significant increase in the propan-2-ol conversion with an increase in the sulfuric acid content to 3–4 wt. % due to the increase in the diisopropyl ether selectivity formation from 5% by an acid catalyst content of 1 wt. % to almost 65% by a sulfuric acid content of 4 wt. %. It is shown that an increase in the sulfuric acid content in the reaction mixture also leads to a significant increase in the reaction product's color according to the iodine scale - almost 5 times, which also indicates the course of side condensation reactions with the double bonds of higher fatty acids participation, which are part of triglycerides composition. It is established that the reaction product's acid number regularly increases with an increase in the acid catalyst content in the reaction mixture. It is shown that the reaction products acid number value is determined by the amount of acid catalyst used. It is established that the activity of the sulfuric acid in the sunflower oil triglycerides transesterification reaction is slightly lower than the activity of cation exchange resin KU-2-8. The cation exchange resin under the same conditions provides more than 15% higher triglycerides conversion with a lower reaction product's color on the iodine scale value and the absence of a diisopropyl ether formation side reaction. It is concluded that using sulfuric acid as a catalyst for triglyceride transesterification by propan-2-ol is entirely possible.

Most studies that claimed changes in smartphone usage during COVID-19 were based on self-reported usage data, e.g. collected through a questionnaire. These studies were also limited to reporting the overall smartphone usage, with no detailed investigation of distinct types of apps. The current study investigates smartphone usage before and after COVID-19. Our study uses a dataset from a smartphone app that objectively logs users' activities, including apps accessed and each app session's start and end time. These were collected during two periods: pre-COVID-19 (161 individuals with 77 females) and during COVID-19 (251 individuals with 159 females). We report on the top 15 apps used in both periods. Mann-Whitney U test was used for the inferential analysis. The results revealed that time spent on the smartphone has increased since COVID-19. Emerging adults were found to spend more time on the smartphone compared to adults during both periods. The time spent on social media apps has increased since COVID-19. Females were found to spend more time on social media than males. Females were also found to be more likely to launch social media apps than males. There has been an increase in the number of people who use gaming apps since the pandemic. Value: The use of objectively collected data is a methodological strength of our study. We draw parallels on the usage of smartphone with contexts similar to COVID-19 period, especially concerning limitation on social gathering, including working from home for extended periods. Our dataset is made available to other researchers for benchmarking and future comparisons.

Published: December 2022

Background
Stillbirth rate is an important indicator of access to quality antenatal and delivery care services. Many previous pocket studies were conducted to assess the magnitude of stillbirth and its association with premature rupture of membrane. However, the level of stillbirth, as well as its relationship with premature rupture of membrane (PROM), varies from study to study. This systematic review and meta-analysis was conducted to estimate the pooled prevalence of stillbirth and its association with the early rupture of membranes in sub-Saharan Africa.
Method
Electronic databases such as PubMed Central PMC, Cochrane library, Medline via Virtual Health Library (VHL), HINARI (Health Inter Network Access to Research Initiative) portal, and Google scholar were used for searching for original articles. The heterogeneity of the studies was checked by I-squared statistics. A Random-effects method was applied to estimate the pooled prevalence of stillbirth and the effect size of the early rupture of membranes in sub-Saharan Africa. Subgroup analysis was performed based on region (East, West, Central, and Southern Africa) and year of study (before 2015 and after 2015). A funnel plot and Egger’s regression test was used to see publication bias.
Result
Pooled prevalence of stillbirth in sub-Saharan Africa was 6.4% (95% CI: 5.5–7.3). In sub-group analysis, Southern African regions had a higher stillbirth prevalence and the western African regions had a lower than East and Southern Africa. The prevalence of stillbirth in the region is increased from 4.1% (95% CI: 2.2–6.0) before 2015 to 7.1% (95% CI: 5.8–8.3) after 2015. The pooled odds ratio results from seven studies showed the non-significant effect of early rupture of membrane on stillbirth (pooled OR = 1.54, 95% CI: 0.26–2.82). According to the regression test (Egger test), there was no small study effects or publication bias (P = 0.108).
Conclusions
The pooled prevalence of stillbirth in sub-Saharan Africa was relativity high. The analysis establishes the minimal effects of early rupture of membrane on stillbirth. Therefore, we recommend that strengthening the testing intervention is crucial to reduce the still relatively high stillbirths.

Published: December 2022

Background: Peanut (Arachis hypogaeaL.) is one of the valuable oilseed crops grown in drought-prone areas worldwide. Drought seriously limits peanut production and productivitysignificantly.
Method and Results: In order to decipher the drought tolerance mechanism in peanut under drought stress, RNA sequencing was performed in TAG -24 (drought tolerant genotype) and JL-24 (drought susceptible genotype). Approximately 51 million raw reads were generated from four different libraries of two genotypes subjected to drought stress exerted by 20% PEG 6000 stress and control conditions, of which ~41 million (80.87%) filtered reads were mapped to the Arachis hypogaea L. reference genome. The transcriptome analysis detected 1,629 differentially expressed genes (DEGs), 186 genes encoding transcription factors (TFs) and 30,199 SSR among the identified DEGs. The comparative analysis between the two genotypes revealed higher and integral tolerance in TAG-24 through activation of key genes involved in, plant hormone signaling pathway, ABA, LEA protein, and oxidative damage.
Conclusion: This genome wide transcription map therefore provides a valuable tool for future transcript profiling under drought stress and enriches the genetic resources available for this important oilseed crop.

Published: December 2022

Background: The aim of this study was to evaluate psychological distress among orthodontic patients and its relationship to orthodontic emergencies related to different appliances during the COVID-19 lockdown.
Methods: This was a cross-sectional online questionnaire survey involving orthodontic patients in Shanghai, China. Data collection occurred from May 15 to June 1 2022. The demographic information and orthodontic emergencies were collected, while the peritraumatic distress symptoms were assessed by the COVID-19 Peritraumatic Distress Index (CPDI). Data analysis was performed by SPSS software.
Results: A total of 480 patients were examined, including 331 fixed appliance patients, 131 clear aligner patients and 18 removable appliance patients. Patients who encountered emergencies and suffered from temporomandibular joint (TMJ) pain reported significantly higher CPDI scores in each group (p<0.01). Multivariate linear analysis showed that patients aged above 18 years old (p<0.01), emergencies in fixed appliance patients (p<0.05), emergencies among clear aligner patients (p<0.01), and higher TMJ-pain scores were significantly associated with increasing CPDI scores.
Conclusions: Orthodontic patients encountered emergencies, especially those who suffered from TMJ pain and were at higher risk of psychological distress related to COVID-19; thus, targeted intervention and self-management guidelines should be designed to relieve anxiety and strengthen coping capacity for orthodontic patients during the pandemic.
Enhancing Mental and Physical Health of Women through Engagement and Retention (EMPOWER) 2.0 QUERI: Study protocol for a cluster-randomized hybrid type 3 implementation-effectiveness trial

Published: December 2022

Background: Women Veterans are the fastest-growing segment of Veterans Health Administration (VA) users. The VA has invested heavily in delivering care for women Veterans that is effective, comprehensive, and gender-tailored. However, gender disparities persist in cardiovascular (CV) and diabetes risk factor control, and the rate of perinatal depression among women Veterans is higher than that among civilian women. Challenges such as distance, rurality, negative perception of VA, discrimination (e.g., toward sexual and/or gender minority individuals), and harassment on VA grounds can further impede women’s regular use of VA care. Enhancing Mental and Physical Health of Women through Engagement and Retention (EMPOWER) 2.0 builds on work to date by expanding access to evidence-based, telehealth preventive and mental health services for women Veterans with high-priority health conditions in rural and urban-isolation areas.
Methods: EMPOWER 2.0 will evaluate two implementation strategies, Replicating Effective Practices (REP) and Evidence-Based Quality Improvement (EBQI), in supporting implementation and sustainment of three evidence-based interventions (Virtual Diabetes Prevention Program; Telephone Lifestyle Coaching Program; and Reach Out, Stay Strong Essentials) focused on preventive and mental health care for women Veterans. We will conduct a mixed-methods implementation evaluation using a cluster-randomized hybrid type 3 effectiveness-implementation trial design to compare the effectiveness of REP and EBQI on improved access to and rates of engagement in telehealth preventive lifestyle and mental health services. Other outcomes of interest include (a) VA performance metrics for telehealth care delivery and related clinical outcomes; (b) progression along the Stages of Implementation Completion; (c) adaptation, sensemaking, and experiences of implementation among multilevel stakeholders; and (d) cost and return on investment. We will also generate implementation playbooks for program partners to support scale-up and spread of these and future evidence-based women’s health programs and policies.
Discussion:EMPOWER 2.0 provides a model for mixed-method hybrid type 3 effectiveness-implementation trial design incorporating evaluation of performance metrics, implementation progress, stakeholder experience, and cost and return on investment, with the ultimate goal of improving access to evidence-based preventive and mental telehealth services for women Veterans with high-priority health conditions.

Quadruplet expanded DNA (QED) genetic code for eukaryotic cells**
Authors: Singh Rama Shankar
Published: December 2022

QED genetic code for eukaryote cells is developed by analyzing triplet gene encoding and overcoming the lack of transcription and splicing regulations. While verifying the triplet genetic code, Nobel laureate H.G. Khorana had trouble synthesizing self-complementarity forming Poly r-dinucleotides adjacent bases, not promoting polypeptide formation, a noncoding. The QED noncoding codon has a similar trait. Here, the QED codon is assumed to comprise all four DNA bases (T, C, A, and G); the code is position-independent and symmetric. The self-complementarity forming adjacent bases (AU) and (C G) with any two NN (N any T, C, A, and G) bases are noncoding. Four DNA bases arranged in a 4x4 square symmetric matrix yield ten independent elements, which set in a 10x10 square symmetric matrix yield 75 independent elements. Under QED assumptions, 75 quadruplets fall into two groups: 20 independent protein-encoding codons and 35 independent noncoding codons applicable to regulating and controlling synthesis, transcription, and splicing processes. Since gene variants lead to dysfunctional protein-causing diseases, steps to correct dysfunctional proteins are described, anticipating a strategy for developing cures for rare diseases and multigenic cancers.
Pathological features of the liver after cure of hepatic sinus obstruction syndrome caused by Tusanqi: Two case reports
Authors: Tan Youwen , He Cong
Published: December 2022

The pathological features of the liver after the clinical cure of hepatic sinus obstruction syndrome caused by Tusanqi have not been described. In this report, we detail the histological manifestations of the liver in two cases.We observed the pathological characteristics of two PA-HSOS patients who were clinically cured after anticoagulant treatment. Slight inflammation and necrosis, hepatic sinus dilatation, perisinusoidal and intrasinusoidal fibrosis, and central venous embolism can still occur; however, there is no reason to believe that these pathological characteristics are the supporting basis for continuing anticoagulant treatment.
