Topology and applications of 2D Dirac and semi-Dirac materials
Authors: Mondal Sayan , Ganguly Sudin , Basu Saurabh 
Published: October 2022

Abstract
Two dimensional (2D) Dirac materials, such as graphene, hold promise of being useful in energy storage, and thus have merged as candidates that are worth exploring through the last couple of decades. In this chapter, we mainly focus on three aspects of these materials, namely, the electronic properties, via computing the band structure, the topological properties through the topological invariants, and the prospects of these 2D materials for spintronic applications, via studying the spin polarized transport. All of these properties are correlated, and hence warrant a thorough discussion. Further, in order to ascertain whether a band deformation induces noticeable effects on the electronic, topological and spintronic properties, we have considered a 2D semi-Dirac system, that does not have Dirac cones, however the conduction and the valence bands touch at an intermediate to the Dirac points in the Brillouin zone. From our studies, we infer that the behaviour of these semi-Dirac systems is quite distinct from their Dirac counterpart. Finally, in order to have noticeable spin polarized transport, we use heavy adatoms (such as, Au) on the graphene matrix which enhances the spin–orbit coupling, and thereby propose a mechanism that will ramify on the spintronic applications.

Published: October 2022

AbstractIn the stone industry, about 73% of the total production is generated as solid waste. In the processing phase, only 20% is produced as harmful ultra-fine sawdust sludge. In the Turah area, Cairo, Egypt, an estimated 448,000 tons are produced annually. About 60% of the total production of dimension stones is carbonate stones. The objective of this study is to properly dispose of the ultrafine pollutants and produce value-added products. The ultrafine marble waste was characterized by different methods such as XRD, XRF, FTIR, particle size analysis and zeta potential. Calcite and dolomite minerals were the main constituents of this waste (91%). The average particle size was 6.656 µm. The fine fraction with a particle size of less than 25 µm contains 97.6% calcite with 81% weight. Sodium N-lauroyl sarcosinate (SNLS) was used as a selective flotation collector for calcite as a calcium mineral. A flotation concentrate with a purity of 99.6% and an overall yield of 80% was obtained at a pH of 9. The bleached product meets ASTM standard specifications for paint and paper applications.
Überbrückungsleistungen für EU-Bürger-/-innen in Deutschland: Instrument sozialer Absicherung oder Migrationskontrolle?
Authors: Bruzelius Cecilia , Ratzmann Nora , Reiß Lea 
Published: October 2022

Abstract
Der Artikel analysiert die sogenannten Überbrückungsleistungen (nach § 23 Abs. 3 SGB XII), welche in Deutschland lebende mittellose EU-Bürger/-innen, die keinen Rechtsanspruch auf Grundsicherung für Arbeitssuchende oder Sozialhilfe haben, für einen begrenzten Zeitraum als Übergangsgeld erhalten können. Die Leistung soll dieser Personengruppe eine minimale soziale Unterstützung für einen begrenzten Zeitraum, vornehmlich bis zur Ausreise aus Deutschland, bieten. Der Artikel analysiert die Umsetzung dieser Leistungen. Ziel ist ein Abgleich zwischen Intentionen des Gesetzgebers und gelebter Praxis sowie eine Diskussion der sozialpolitischen Folgen für Leistungsbezieher/-innen, die unter anderem durch die Verschränkung von Sozial- und EU-Freizügigkeitsrecht entstehen. Neben einem Überblick über die Gesetzlage und deren politischen Hintergrund gewährt der Artikel daher Einblicke in die Gewährungspraxis und Inanspruchnahme der Leistung. Die Ergebnisse der hierfür durchgeführten qualitativen Erhebung offenbaren unterschiedliche Praktiken und Umsetzungsdefizite, die auf einen Mangel an praktischen Erfahrungen, Rechtsunsicherheiten sowie bürokratische Hürden in der Antragsstellung zurückzuführen sind. Insgesamt kommt der Artikel zu dem Schluss, dass Überbrückungsleistungen, wie bereits im Gesetz angelegt, keine soziale Mindestabsicherung mittelloser EU-Bürger/-innen darstellen, auch wenn sie gelegentlich zur Überbrückung einer finanziellen beziehungsweise sozialen Notlage beitragen. Ferner wird durch die oft restriktive Umsetzungspraxis die Prekarisierung der Zielgruppe verstärkt, sodass Überbrückungsleistungen de facto eine Verschränkung von Sozialleistungsbezug und Migrationssteuerung darstellen und als Instrument der Migrationskontrolle im freizügigen Europa gewertet werden können.

Abstract
Produktionslinien für Batterieelektroden bestehen aus hoch produktiven aber starren Prozessen. So können Änderungen nur langsam umgesetzt werden, und eine Reaktion auf neue Bedingungen ist kaum möglich. Im Projekt ReFlexBat (Regelbare Beschichtungseinheit für die flexible Beschichtung von Batterieelektroden) wird deshalb eine autonome Beschichtungseinheit entwickelt, um den Anfahrprozess zu beschleunigen, auf neue Randbedingungen zu reagieren und allgemein den Ausschuss im Beschichtungsprozess zu reduzieren. Bisher erfolgte zum einen die Erarbeitung des Konzepts, zum anderen wurde die notwendige Präzision zum Erreichen der Qualitätsziele bestätigt.
Avatares del sujeto cartesiano
Authors: Espinosa Proa Sergio 
Published: October 2022

El sujeto cartesiano se constituye en la subordinación de todas las facultades a la inteligencia; ella ha de imponer en todo momento y situación sus condiciones, porque de lo que se trata es de asegurar el dominio de las cosas, algo que no se consigue sin interponer al deseo, a ese deseo, un entendimiento adecuado. Y Descartes sabe muy bien que no hay entendimiento que no sea de objetos. Los seres humanos están dotados de estas facultades, que habitualmente chocan y no dejan de entrar en conflicto. En la sustitución de la confusión (y la superstición) por el método, Descartes lleva a su extremo la sujeción de las demás facultades por el entendimiento, injusticia que sublevará a muchos. En este artículo se aborda este problema.

Authors: Wang L.P. , Wang Z.F. , Reziwangul S. , Chen S.E. 
Published: October 2022

AbstractThis study optimised the hydrolysis process of chicken plasma protein and explored the in vivo antioxidant activity of its hydrolysates. The results showed that alkaline protease provided the highest degree of hydrolysis (19.30%), the best antioxidant effect in vitro. The optimal hydrolysis process of alkaline protease was: temperature 50 °C, time 8 h, [E]/[S] 7000 U g−1, pH 7.5. Antioxidant studies in vivo showed that the low, medium, and high dose groups significantly reduced the serum MDA and protein carbonyl content (P < 0.05) and significantly increased the serum SOD and GSH contents (P < 0.05). The results of HE staining of the liver showed that the liver cells in the model group were severely damaged, but the chicken plasma protein hydrolysates could alleviate this pathological damage. Chicken plasma protein hydrolysis products had certain antioxidant activity.

AbstractHungarian pond fish production is based on grains, but in the last few years, new ideas and efforts have appeared to intensify carp production technology. The basic objective was to change grain-based feeding to nutritionally complete feeds, which ensure rapid growth and more efficient feed conversion rates. This study aimed to utilise empty ponds during the summer period for carp production. Thus, there is no need for fish producers to catch fish in large ponds at the operating water level to satisfy smaller market demands appearing during the summer.The other aim was to compare the meat quality of fish raised on traditional and nutritionally complete feed until market size in the last year of production. Fatty acid profile and the levels of saturated, monounsaturated, and polyunsaturated fatty acids in fish fillets were specified, and their ratios were analysed. The result showed that nutritionally complete feed with different fatty acid composition affects the fatty acid composition of carp fillet during the rearing period. Quality of the fillet of carp fed with higher unsaturated fatty acid content became more favourable to the consumers due to health promoting effect of polyunsaturated fatty acids.

Published: October 2022

The new phase Ba5In2Al2Zr0.9Nb0.1O13.05 with hexagonal perovskite structure was obtained. The substitution of Zr4+ by smaller Nb5+ was accompanied by the incorporation of the oxygen interstitials and did not lead to a significant change in the lattice parameters. It was established that the investigated sample was capable for water incorporation from the gas phase, the hydration degree value was 0.24 mol H2O. IR-spectroscopy analysis defined the presence of OH−-groups with different thermal stability, which participate in different hydrogen bonds. The new phase Ba5In2Al2Zr0.9Nb0.1O13.05 demonstrates the predominant protonic conductivity at pH2O = 2·10−2 atm and Т600 °C.
Local structure and ionic transport in acceptor-doped layered perovskite BaLa2In2O7
Authors: Tarasova Nataliia A. 
Published: October 2022

Materials with perovskite or perovskite-related structure have many applications because of theirs different physical and chemical properties. These applications are extremely diverse and cover different fields including hydrogen energy. Layered perovskites with Ruddlesden-Popper structure constitute a novel class of ionic conductors. In this paper, the effect of acceptor doping on the local structure and its relationship with transport properties were shown for layered perovskites based on BaLa2In2O7 for the first time. The geometric factor (the increase in the unit cell volume due to the increase in the ionic radii of cations) plays major role in the area of small dopant concentration (x 0.15). The concentration factor (the increase in the oxygen vacancy concentration) is more significant in the area of big dopant concentration (x 0.15). The acceptor doping is a promising way of improving the oxygen-ionic conductivity of layered perovskite BaLa2In2O7.

Authors: Breyfogle Sarah 
Published: October 2022

ABSTRACTUsing cultural trauma theory and literary trauma theory, this paper examines how fanfiction writers used ficwriting to explore pandemic trauma. It conducts a textual analysis of five fics that center their plot around some aspect of COVID‐19 precautions and restrictions. This research finds that the authors demonstrate community care; that they self‐disclose that they or others they know are struggling; and that actual infection, illness, or death are rarely presented within the fics.

Published: October 2022

Background and Objectives: Vaccination being the only way to reduce mortality from the dreaded COVID-19 disease, the vaccine was introduced in India as per the advice of the National Expert Group on January 16, 2021. Duration of immune response elicited by the vaccines has always been a matter of content.With new variants emerging every other day, the study was done to look for the antibody response in vaccine recipients post second dose of vaccination.
Materials and Methods: A longitudinal observational study was conducted from August 2021 to February 2022 in fully vaccinated individuals who tookeither Covishield (AZD1222) or Covaxin (BBV-152). Blood was collected from the individ- uals at 12-16 weeks post-vaccination to look for IgG antibodyresponse against S1 spike protein of SARS-CoV2 by ELISA. Follow-up was done at 32 weeks post the second dose in individuals who had received Covishield.
Results: Among 176 individuals, IgG antibody against S1 spike protein was found to be positive in 89.7% (158). Covishield recipients showed higher antibodyresponse (99.1%) as compared to Covaxin recipients (71%). Antibody response was high- er in males, individuals less than 50 years, and non-comorbidindividuals. Of 38 Covishield recipients, IgG antibody response was positive in 28 (73.6%) individuals when followed up at 32 weeks post the second vaccination dose.
Conclusion: The study gives us input with regard to the long-term antibody kinetics of both vaccines. The study has a follow-up plan to co-relate the antibody response to the neutralization test.

Published: October 2022

Background and Objectives: There is a poor understanding about the prevalence and characteristics of secondary bacterial and fungal infections among Coronavirus diseases 2019 (COVID-19) superinfection in hospitalized patients.
Materials and Methods: Four hundred COVID-19-proven patients were enrolled in this study. Nasal swabs for molecular assay (Real-time PCR) and sputum samples for further microbiological assays were collected. Following a broad-spectrum search, a meta-analysis was performed using StatsDirect software (version 2.7.9) according to the DerSimonian and Laird method applying the random-effects models.
Results: Streptococcus spp. (21.5%) and Staphylococcus spp. (16.7%) had the highest prevalence of bacterial coinfection among the COVID-19 patients,while Acinetobacter spp. had the lowest prevalence (4.2%). Among fungal coinfections, Candida albicans was the most prevalent (6.7%), and Aspergillus spp.was the lowest (2%). Males, elderly patients, patients with a history of underlying diseases and drug use, patients who showed acute clinical symptoms, andpatients with a pro- longed hospital stay had a higher incidence of secondary infections (P-value <0.05). The pooled prevalence for bacterial and fungal coinfections was 33.52% (95% CI: 18.12 to 50.98; I2: 99.4%; P-value: <0.0001).
Conclusion: We suggest designing additional research with a larger target population and diagnostic molecular analyses to depict a more realistic view of the coinfection status.

Background and Objectives: Identification of pnemococcal serotypes and antimicrobial resistance provides helpful infor- mation for the use of suitablevaccines and antibiotics; however, very limited data is available on these issues in Vietnam. The present study aimed to find the serotype distribution and drugresistance patterns of Streptococcus pneumoniae isolated from unvaccinated children less than 5 years of age with pneumonia at a province in centre Vietnam.
Materials and Methods: A total of 126 clinical pnemococcal strains isolated from unvaccinated children less than 5 years of age with pneumonia at theNghe An province, Vietnam between Nov 2019 and Mar 2021. All strains were identified using conventional microbiological method, VITEK® 2 Compactsystem, specific PCR and sequencing. The serotypes and antimicrobial resistance patterns of pnemococcal strains were determined using the multiplex PCRassays and VITEK® 2 Compact system.
Results: The results showed that, eight different pneumococcal serotypes were identified. The most common serotypes were 19F (67.46%), followed by23F (10.32%), 19A (9.52%), 6A/B (3.17%), 15A (2.38%), 9V (3.17%), 11A (1.59%) and 14 (0.80%), respectively. More than half of the pneumococcal strainswere non-susceptible to penicillin. The resistance rate to ceftriaxone and cefotaxime were 41.3% and 50.8%. The percentage of pneumococci strains resistantto clarithromycin, azi- thromycin, erythromycin, cotrimoxazole, tetracyclin, and clindamycin were more than 93% of all strains. All pneumococcal serotypes were highly resistant to clarithromycin, azithromycin, erythromycin, cotrimoxazole, and clindamycin.
Conclusion: Our findings showed high antibioticresistance rates of the strains causing pneumococcal pneumonia, mostly macrolide resistance, among unvaccinated children.

Authors: Rouhizohrab Nasim , Mohammadipanah Fatemeh 
Published: October 2022

Background and Objectives: Myxobacteria initially recognized by their complex life cycle and social behavior are progres- sively explored for their bioactive secondary metabolites. However, isolation of myxobacteria usually is accompanied by bacterial and fungal contaminations due to the direct cultivation of soilon isolation media, which results in severe challenges in the purification of myxobacteria. Therefore, it is necessary to improve their purification techniquesfrom natural samples to the discovery of new biomolecules.
Materials and Methods: In the present study, six physichochemical methods were assessed for their efficacy in the purifi- cation of myxobacterial strains and specially from contaminants of Microvirga spp.
Results: Among the evaluated treatments, purification of fruiting bodies using a combination of ultrasonication and heat treatment was identified as theeffective protocol with 80% success rate in the purification of myxobacterial strains and re- ducing up to 90% of the contaminating bacteria.
Conclusion: Concerning the problematic contamination of myxobacterial isolates, the introduced approach can retrieve the myxobacterial strains which areoften suppressed by the over growth of contaminations especially root symbiotic bacteria namely Microvirga spp.

Published: October 2022

Background and Objectives: Cryptococcosis is an opportunistic mycosis, caused by Cryptococcus neoformans. Crypto- coccal meningitis is one of themost fatal opportunistic infections associated with human immunodeficiency virus (HIV) infection. The aim of this study was to find the prevalence ofcryptococcal antigenemia in people living with HIV (PLHA) and also to find the prevalence of opportunistic infections among these patients.
Materials and Methods: A total of 204 non duplicate samples were collected from people with HIV aged above 18 years. Samples with CD4 count less than300 were included in the study. Cryptococcal antigen detection was done by CrAg Lateral flow assay.
Results: None of the patients in our study were positive for cryptococcal antigen. Opportunistic infections were observed in 82 (40.2%) HIV positive patients. Candidiasis, tuberculosis and Pneumocystis jiroveci pneumonia were the most common opportunistic infections.
Conclusion: This is the first study from the southern state of Kerala on the prevalence of Cryptococcal antigenemia among HIV positive individuals. Thestudy showed that routine screening for cryptococcal antigen will not be cost effective in our population. Similar to other studies, eventhough candidiasis,tuberculosis and PCP were more commonly seen among people with CD4 count < 200 cells/mm3, there was no statistically significant association.
Treatment of a Lisfranc Injury in a 7-Year-Old Boy
Authors: Kraft Denver B. , Howard Jason J. 
Published: October 2022

Case:
This is a case of a 7-year-old boy with a Lisfranc injury identified on weight-bearing films who was treated successfully with closed reduction with a clamp and smooth pin fixation. This patient returned to sports without pain or radiographic signs of arthritis at 1 year.

Conclusion:
Lisfranc fractures and ligamentous injuries are rare and can occur in skeletally immature children. They have high potential for long-term disability if not properly diagnosed and treated. Although there is no consensus on optimal management of pediatric Lisfranc injuries, restoration of an anatomic Lisfranc joint with smooth pins and immobilization for 6 weeks is a viable treatment option.
Comparative Evaluation on the Coupled Fracture Characteristics for Longmaxi Anisotropic Shale

Published: October 2022

Abstract
The shale fracture characteristics are important for realizing the complex hydraulic fracture network, predicting wellbore fracture pressure, and optimizing wellbore trajectory and the rock fragmentation efficiency. Through a three-point bending test of notched semicircular specimens of Longmaxi shale, the coupled relationship of mode-I fracture toughness (Kic), peak fracture force (Pmax), energy release rate (GI), applied work (W), and loading rate was studied by using kernel density analysis method. The results showed that the dynamic characteristics of force-displacement curve exhibited obvious loading angle dependence, including two types of the “deformation accumulation-brittleness” and “deformation accumulation-brittleness-plasticity.” The Kic and GI increased linearly with Pmax increasing. With the increasing of the loading angle, the dispersion degree of Pmax, Kic, GI, and W all increased. The GI increased nonlinearly with the increasing of Kic. With the increasing of the loading rate, the Kic basically increased linearly. The dynamic Kic under static and quasistatic conditions had strong anisotropy. At the high loading rate, the anisotropy index gradually decreased as the loading rate increasing. The results have significant implications for the design of hydraulic fracturing and the exact fracture control of Longmaxi shale.
