Published: August 2020

AbstractMicrotubules play an important role in brain functioning and purported to alter in several neurological disorders including Alzheimer's disease, Parkinson disease, malignancies and brain injuries. Creating a molecular imaging probe that binds to microtubules in brain would significantly benefit the diagnosis and stratification of patients based on therapeutic treatments that target neurotubulin pathology. We have previously reported the first‐ and second‐generation microtubule Positron Emission Tomography (PET) ligands, which exhibited blood brain barrier permeability and accumulation in brain. We are continuing the search for new microtubule agents in order to establish the most selective PET agent with optimal attributes for in vivo quantification of the brain microtubules in diseases. Hence, we identified a high‐affinity microtubule agent namely, WX‐MB‐18B (GI50= 1.9 nM, IC50=0.45‐0.99 nM). In addition to the high affinity to microtubules, WX132‐18B has adequate lipophilicity for facile brain entry and also is amenable for 11 C‐radiolabeling. Herein we report the radiochemical synthesis and initial PET evaluation of [11C]WX‐132‐18B in mice to determine its ability for imaging brain microtubules.

AbstractWe have developed an efficient and eco‐friendly method of disulfides synthesis in water using surfactant (DODAB). This reaction is catalysed by chlorophyll and fluorescent lamp is used as source of energy. This, one pot, ultra fast reaction, which involve a photo‐induced electron transfer (PET) mechanism, affords a green and efficient strategy for the conversion of commercially available aromatic thiols into diversified disulfides. This rapid synthesis allows the formation of various disulphides in the range of 80–94% yield at room temperature.

Published: August 2020

AbstractParacetamol (PA), being an analgesic and antipyretic medicine, can cause fatal hepatotoxicity and nephrotoxicity when overdosed. It is therefore important to develop electrochemical sensors that can monitor and quantify it in aquatic environments. In this study, rare‐earth sandwich‐type phthalocyaninato chelates based on neodymium (1 a) and samarium (1 b) were employed as electrocatalysts to modify glassy carbon electrodes (GCE) for the first time. It was found that 1 a‐modified GCE (herein referred to as 1 a‐GCE) is less conductive than 1 b‐modified counterpart (1 b‐GCE). A larger rate constant was also obtained for 1 b‐GCE. It was established that a faster oxidation rate efficiency was responsible for lower limit of detection value obtained for 1 b‐GCE as compared to 1 a‐GCE.
Theoretical Insights into Y2C2@C82: Vibrational Frequency Influencing the Thermodynamic Stability
Authors: Zhao Ruisheng , Liu Zhizhong , Yuan Kun , Zhao Xiang 
Published: August 2020

AbstractY2C2@C82series (as well as Y2@C84series) and the parent C82cages were investigated by density functional theory in conjunction with statistical thermodynamic analyses. C2(39717)‐C82is the most stable isomer of pristine C82cages, and Y2@D2d(51591)‐C84is the most low‐lying isomer of Y2C84series. At the temperature range of fullerene formation, C2(39712)‐C82, Cs(39713)‐C82, and C3v(39717)‐C82are the three most abundant C82isomers, and Y2C2@Cs(39715)‐C82, Y2C2@C3v(39717)‐C82, and Y2C2@C2v(39718)‐C82are the three only abundant Y2C84isomers. However, mole fraction of Y2@D2d(51591)‐C84turns to be very low at the high temperature range. Further statistical thermodynamic analyses revealed that vibrational frequencies are the underlying reason for high abundances of Y2C2@Cs(39715)‐C82, Y2C2@C3v(39717)‐C82, and Y2C2@C2v(39718)‐C82and low abundance of Y2@D2d(51591)‐C82at high temperature range. The statistical thermodynamic analysis approach to separately consider energy, rotation and vibration partition functions can be used to investigate other endohedral metallofullerenes.

Published: August 2020

AbstractThis paper describes the potential of waste biomass derived biochar for improvement in the dye wastewater treatment in a microbial fuel cell (MFC). The complete MFC, an energy generating unit, was made with the waste products in order to demonstrate that low cost alternatives are available to replicate the positive results. Waste corncob derived biochar produced after acid modification has been evaluated as a supplement in an MFC for treatment of real dye wastewater (RDW). The two doses of sulfuric acid modified corncob biochar (SA‐MCB), (0.5 g and 1 g) and a blank (without any dose) were assessed for the effect on MFC performance. The maximum power density (49.92 W/m2), current density (0.28 A/m2), COD removal efficiency (88.39%), decolorization efficiency (81.6%) and TDS reduction (84.4%) were obtained with 0.5 g biochar dose. The Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) analysis revealed the structural changes occurring on the SA‐MCB after use in the MFC. The SEM analysis revealed the better biofilm formation due to SA‐MCB deposition. Power density with 0.5 g of SA‐MCB dose improved to more than 24 times in comparison to the system without any such dose. The UV spectrophotometer analysis confirmed the azo bond deformation during treatment. The overall results suggest that the use of SA‐MCB biochar as anode material and as a supplement in the MFC system may provide an effective anode‐biofilm in MFCs for wastewater treatment.
Experimental Investigation with DFT Analysis Towards a Promising Recyclable Photocatalyst from g‐C3N4/ZnS Nanocomposite
Authors: Mukherjee Biswanath 
Published: August 2020

AbstractIn‐situ synthesis of highly crystalline graphitic carbon nitride (g‐C3N4)/ZnS nanosphere via solution route is reported. The g‐C3N4/ZnS nanocomposite exhibited reproducible photocatalytic activity with more than 95 % degradation of Rhodamine B (RhB) under UV illumination with apparent rate constant of 0.0168 min−1, compared to pristine ZnS nanosphere which produced only 80 % degradation of RhB under the same condition. Density functional theory calculation indicated the existence of large built‐in potential (ca. 6.8 eV) at the interface of g‐C3N4/ZnS composite heterostructure that promotes effective charge transfer from ZnS to g‐C3N4 layer. The Bader charge analysis dictated a net charge transfer of
from ZnS to g‐C3N4 layer. The DFT prediction along with photoluminescent spectroscopy confirmed that improvement in photocatalytic performance of as‐prepared g‐C3N4/ZnS nanocomposite over pristine components can be ascribed to the reduction in carrier recombination followed by effective separation and transportation of charges at g‐C3N4/ZnS interface.
Introduction
Authors: van Gageldonk Maarten , Munteán László , Shobeiri Ali 
Published: August 2020

AbstractThe above epigraph to Marquez’s autobiography,Living to Tell the Tale,highlights the difference between the actual past and the past kept alive in memory. It is not so much that we remember what happened in the past per se, but by way of remembering and sharing our memories, we create a narrative of that past. The stories that we tell of our lives (as well as the ones that we choose not to tell) are the building blocks of the identities we fashion of ourselves as well as of our communities. It is in this sense that the memories we recount are constitutive of what Marquez calls life. By foregrounding the role of remembering in the construction of identity, the epigraph encapsulates one of the fundamental precepts of memory studies, namely that memory is more than a mere recollection of what actually happened in the past. Rather, it is a “fluid and flexible affair,” as Bond et al. (2018, 1) assert, a performative practice mediated through various modes of recounting such as places, rituals, as well as a variety of textual, visual, and other sensory media (Bal et al. 1999; Erll and Rigney 2009; Plate and Smelik 2013). Animation is one of these media. Whether made in pencil, paint, clay, paper, or sand, through the use of pin-screen or the landscape, with puppets or created by computer, what different forms of animation share is “the capacity for plasticity,” as Dobson et al. (2019, 8) recently observed. It is this plasticity, combined with the freedom animation offers to escape from the indexical qualities inherent to film, that makes it a particularly productive mnemonic medium. This book sets out to explore this dimension of animation.

Zusammenfassung
Die Einheit von Forschung und Lehre – dieser Grundgedanke des Humboldt’schen Bildungsideals liegt meist zugrunde, wenn von Forschendem Lernen gesprochen wird. Doch nicht nur Forschendes Lernen, sondern auch Forschungsbasiertes, Forschungsorientiertes oder Forschungsnahes Lernen sind heutzutage in aller Munde, wie die Vielzahl von Publikationen in den letzten Jahren zeigt. Ist mit dem Forschenden Lernen für die universitäre Lehre ein Allheilmittel gegen die „Verschulung des Studiums in der von Bologna gebeutelten Hochschullandschaft“ (Ukley & Gröben, 2018, S. IX) gefunden worden? Alle, die sich tiefer mit dem didaktischen Format des Forschenden Lernens auseinandersetzen, wissen: So einfach ist es nicht.

Spectra of elliptic potentials and supersymmetric gauge theories
Authors: He Wei 
Published: August 2020

Abstract
We study a relation between asymptotic spectra of the quantum mechanics problem with a four components elliptic function potential, the Darboux-Treibich-Verdier (DTV) potential, and the Omega background deformed N=2 supersymmetric SU(2) QCD models with four massive flavors in the Nekrasov-Shatashvili limit. The weak coupling spectral solution of the DTV potential is related to the instanton partition function of supersymmetric QCD with surface operator. There are two strong coupling spectral solutions of the DTV potential, they are related to the strong coupling expansions of gauge theory prepotential at the magnetic and dyonic points in the moduli space. A set of duality transformations relate the two strong coupling expansions for spectral solution, and for gauge theory prepotential.

The quadrature formulas are computed by integrating over S a polynomial approximant of f which uses functional and derivative values at the vertices of S.

We give the formula for the order projection onto this band, and we obtain an analytic representation for atomic operators between spaces of measurable functions. Finally, we consider the procedure of the extension of an atomic map from a lateral ideal to the whole space.
Verletzung der A. profunda femoris mit transfusionspflichtiger Blutung durch sekundäre Dislokation des Trochanter minor nach Osteosynthese einer pertrochantären Femurfraktur
Authors: Hertig D. , Thalmann R. , Rufer B. 
Published: August 2020

ZusammenfassungEin 95-jähriger Patient erlitt eine transfusionspflichtige Blutung nach Osteosynthese einer pertrochantären Femurfraktur mittels proximalem Femurnagel. Das bei der Erstmobilisation sekundär dislozierte Fragment des Trochanter minor perforierte einen Seitenast der A. profunda femoris. Die Blutung konnte mittels Embolisation gestillt werden, und der Patient wurde wenige Tage später mit stabilem Hämoglobinwert entlassen. Wiederholt sinkende Hämoglobinwerte trotz mehrmaliger Bluttransfusion weisen auf eine aktive Blutung hin. Die genaue Identifikation der Blutungsquelle nach Osteosynthese proximaler Femurfrakturen ist entscheidend für die korrekte Therapie.

SummaryThis is a report on the first identified cases of coronavirus disease 2019 (COVID-19) in Austria. The first documented case was a person who stayed in Kühtai, Tyrol, from 24 to 26 January 2020, and had been infected by a Chinese instructor in Starnberg (Germany) between 20 and 22 January. This counts as a German case since her diagnosis was eventually made in Munich (Germany) on 28 January. On 25 February, two cases imported from Italy were diagnosed in Innsbruck but again no secondary cases were identified in Austria. The first three infections of Austrian inhabitants were detected on 27 February in Vienna. The two resulting clusters finally included 6 (source of initial infection unknown) and 61 cases. Most likely, Italy was the source of the latter cluster. On 12 March the first fatal case of COVID-19 in Austria was reported, a 69-year-old Viennese who died in a Vienna hospital after returning from a cruise ship tour in Italy. On 6 March three autochthonously acquired cases were reported in the Tyrol, all related to the ski resort Ischgl. Of the first 14 Islandic COVID-19 cases infected in Ischgl, 11 had already returned to Iceland on 29 February. We consider that the incriminated barkeeper, who tested PCR positive on 7 March, was neither the primary case nor a superspreader. In our opinion, undetected transmission of SARS-CoV‑2 had been ongoing in Ischgl prior to the first laboratory confirmed cases. Our data also underline that the introduction of SARS-CoV‑2 into Austria was not one single event.
Characteristic Curves of the Lennard-Jones Fluid
Authors: Stephan Simon , Deiters Ulrich K. 
Published: August 2020

AbstractEquations of state based on intermolecular potentials are often developed about the Lennard-Jones (LJ) potential. Many of such EOS have been proposed in the past. In this work, 20 LJ EOS were examined regarding their performance on Brown’s characteristic curves and characteristic state points. Brown’s characteristic curves are directly related to the virial coefficients at specific state points, which can be computed exactly from the intermolecular potential. Therefore, also the second and third virial coefficient of the LJ fluid were investigated. This approach allows a comparison of available LJ EOS at extreme conditions. Physically based, empirical, and semi-theoretical LJ EOS were examined. Most investigated LJ EOS exhibit some unphysical artifacts.
The biomechanical evaluation of magnetic forces to drive osteogenesis in newborn’s with cleft lip and palate

Published: August 2020

AbstractThis study examined the potential for dental magnets to act as a driving force for osteogenesis in the palate of newborns with a unilateral cleft lip and palate. In the first part of the study dental magnets were arranged in a set up mimicking a distraction device and the curves of the magnetic attraction force versus gap distance curves generated, with and without the presence of palatal rugae tissue in between both sides of the distraction device. The attraction forces ranged from 1 to 12 N depending on the gap distance and the presence of soft tissue in the gap. In the second part of the study these forces were used as input for a 3D finite element model of the palate of a newborn affected by unilateral cleft lip and palate. In the analysis of load transfer, it was found that the strains generated by a magnetically induced distraction exceed 1,500 µstrain suggesting that bone locally is submitted to mild overload leading to bone apposition.
Street-connectedness and education in Kenya: Experiences of formal schooling as rationale for inclusive pedagogies of practice
Authors: Corcoran Su Lyn , Awimbo Lillian Aoko , Mugwanga Kelvin , Aluoch Irene Atieno 
Published: August 2020

AbstractThis article contributes to the literature on street-connectedness and inclusive education, presenting original research findings from two Kenyan studies. Both studies aim to understand street-connected young people’s experiences of education. The first focused on transitioning from the street into education or training, to explore the challenges of making that transition. The second focused on young people who had lived on the street for extended periods of time and were still there at the time of data generation. Both studies generated significant insight into (a) education as motivating initial migrations to the street, (b) the role of fear, embarrassment, and shame in preventing young people from going (back) into formal education, and (c) how acceptance and support are key to overcoming feelings of not belonging and other challenges when transitioning from the street into school. The article provides empirical evidence that should be considered when planning inclusive education provision for street-connected young people globally.
Antinomism in Twentieth-Century Russian Philosophy: The Case of Pavel Florensky
Authors: Moore Harry James 
Published: August 2020

AbstractThis study examines the notion of antinomy, or unavoidable contradiction, in the work of Pavel Florensky (1882–1937). Many Russian philosophers of the Silver Age shared a common conviction which is yet to receive sufficient attention in critical literature, either in Russia or abroad. This is namely a philosophical and theological dependence on unavoidable contradiction, paradox, or antinomy. The history of antinomy and its Russian reception is introduced here before a new framework for understanding Russian antinomism is defended. This is namely the anticipation of ‘vertical’ antinomies in ‘horizontal’ antinomies. Here, by ‘horizontal’ we suppose an unavoidable contradiction of reason or philosophical reflection, and by ‘vertical’ an unavoidable contradiction of revelation, faith, or a self-contradictory dogma. The study aims to demonstrate that Florensky fails to provide a satisfactory anticipation of vertical antinomies.
