Influence of fractional carbon-dioxide laser in comparison to ErCr-YSGG on the dentin bond integrity of bioactive materials
Authors: Al Jeaidi Zaid A. 
Published: February 2020

Objective: The aim was to assess the influence of Er,Cr:YSGG laser (ECL) and fractional carbon dioxide laser (FCL) on the shear bond strength (SBS) and microleakage of bioactive restorative material to dentin.
Methods: The study was performed in King Saud university in the month of June-July 2019. One hundred and twenty permanent teeth were vertically placed in acrylic resin. Based on the type of surface treatment regime (n=40), samples were divided into three groups. Group-I samples were surface conditioned with total etch and rinse (TE); Group-2 samples were surface treated with Er,Cr:YSGG laser (ECL) and Group-3 specimens were conditioned with fractional carbon dioxide laser (FCL). Surface treatment of dentin was followed by type of bulk fill resin (BFR) application. Tetric-N-Ceram was bonded to dentin conditioned with TE (n=20), FCL (n=20) and ECL (n=20). Similarly, bioactive material (BAM) was also bonded to conditioned surface (n=60). Samples (n=10) among each group were placed in a Universal testing machine. For microleakage testing 5 pairs of samples from each group (n=10) were placed in solution of 2% methylene blue for 24h Fracture analysis was performed using stereomicroscope at 40x magnification. Descriptive statistics i.e., means and standard for SBS and microleakage were compared using analysis of variance (ANOVA) and Tukey’s post hoc test at a significance level of (p < 0.05)
Results: The highest SBS scores were displayed by TE-BFR (Bulk filled resin) (19.21 ± 0.925 Mpa) and the lowest shear bond scores were presented by FCL-BFR (11.06±1.611 Mpa). The lowest microleakage scores were exhibited by group ECL-BFR (24.11±13.01nm). Similarly, the highest microleakage score was displayed in group FCL-BAM (42.18±16.32 nm). Admixed failure was pertinent in groups conditioned by ECL. Moreover, groups conditioned with FCL adhesive type of failure was found in abundance.
Conclusions: ECL has a potential to be used as an alternate to total etch and rinse for conditioning of dentin when bonded to bioactive materials.

Authors: Rafi Aisha , Sayeed Sana , Anwar Muhammad Idrees 
Published: February 2020

Objective: To determine the morphological variations and location of pterion in Pakistani male population.
Methods: This retrospective observational study was carried out in the Department of Radiology, Shifa International Hospital from December 2018 to June 2019. The sample size was calculated by Open Epi web-based calculator. Fifty-three cranial CT scans with slice thickness of 0.5mm; consecutive scans of males were randomly selected. The patients with no craniofacial fracture and ages from 25 to 45 years were included. The dataset was obtained from Toshiba Aquilion One, 360-slice MDCT. The images were imported into the imaging software PACS (WFM), and analyzed in maximum intensity projection mode with three dimensional multiplanar reconstruction viewers. Measurements were taken in lateral projections of skull in Frankfurt plane, as horizontal and vertical distance from the posterolateral margin of frontozygomatic suture to center of pterion. Vertical distance from the superior border of zygomaticotemporal arch to the center of pterion. The morphological types were also recognized.
Results: The type of pterion on right side was 94.3% sphenoparietal 5.6% epipteric whereas left side was (90.5%) sphenoparietal (3.7%) epipteric, (3.7%) stellate type, (1.8%) frontotemporal type. The mean horizontal and vertical frontozygomatic measurements on right side were 2.23±0.22cm and 1.25±0.219 cm respectively. The same measurements on the left side were 2.27-±0.25 cm and 1.226-±0.22 cm respectively. The mean zygomaticotemporal measurements on the right and left sides were 3.45±0.29cm and 3.44±0.25 cm respectively. The mean distance on right and left side of skull was statistically insignificant.
Conclusion: The study provides useful data for position and location of pterion for safe neurosurgical procedures via pterion. Moreover, the knowledge about different morphological types of pterion help the radiologist to differentiate between a fracture line and normal morphological variety.

Życzliwość jako cnota moralna w polskiej filozofii moralnej
Authors: Barański Jarosław 
Published: February 2020

Życzliwość w tradycji polskiej filozofii moralnej wywodzi się z gościnności. Treść zobowiązania do gościnności wypełnia pojęcie ludzkości, a następnie, od przełomu XIX i XX wieku, także dzięki inspiracji oświecenia szkockiego, przechodzi w kategorię życzliwości. Jest ona postrzegana jako cnota i źródło moralnej praktyki, jako zalążek wartościowych postaw i fundamentalna zasada społecznego życia. Autor artykułu odwołuje się do myśli Witołda Rubczyńskiego, Czesława Znamierowskiego, Tadeusza Kotarbińskiego oraz Henryka Elzenberga, aby uzasadnić, że życzliwość, bezinteresowna i bezwarunkowa, jest najbardziej pożądaną zaletą moralną, która powinna być kształcona i pielęgnowana dla polepszania współżycia społecznego.

Electrochemical antioxidant screening and evaluation based on guanine and chitosan immobilized MoS2 nanosheet modified glassy carbon electrode (guanine/CS/MoS2/GCE)
Authors: Tang Ping , Tang Xiaosheng , Mei Shiyong , Xie Yixi , Liu Liangliang , Ren Licheng 
Published: February 2020

AbstractIn this study, an electrochemical biosensor based on guanine and chitosan immobilized MoS2 nanosheet modified glassy carbon electrode (guanine/CS/MoS2/GCE) was developed and employed for antioxidant screening and antioxidant capacity evaluation. The oxidation peak current of guanine was improved and nearly tripled after modifications of chitosan and MoS2 nanosheet. The immobilized guanine could be damaged by hydroxyl radicals generated in Fenton solution. However, in the presence of antioxidants, the guanine was protected and the oxidation peak current of guanine increased. This process mimics the mechanism of antioxidant protection in human body. The factors affecting preparation of sensor and detection of antioxidant capacity were optimized. At the optimum conditions, the guanine/CS/MoS2/GCE showed wide linear range, low detection limit, satisfactory reproducibility and stability for detection. Ascorbic acid was used as a model antioxidant to evaluate the antioxidant capacity. A good linearity was observed with a correlation coefficient of 0.9959 in the concentrations between 0.5 and 4.0 mg L-1. The antioxidant capacities of three flavonoids were also tested and the rank of antioxidant capacities was ascorbic acid (51.84%), quercetin (45.82%), fisetin (34.39%) and catechin (16.99%). Due to the rapid measurement and low cost, this sensor could provide an available sensing platform for antioxidant screening and evaluation.
A Bayesian Framework for Robust Quantitative Trait Locus Mapping and Outlier Detection
Authors: Mutshinda Crispin M. , Irwin Andrew J. , Sillanpää Mikko J. 
Published: February 2020

Abstract
We introduce a Bayesian framework for simultaneous feature selection and outlier detection in sparse high-dimensional regression models, with a focus on quantitative trait locus (QTL) mapping in experimental crosses. More specifically, we incorporate the robust mean shift outlier handling mechanism into the multiple QTL mapping regression model and apply LASSO regularization concurrently to the genetic effects and the mean-shift terms through the flexible extended Bayesian LASSO (EBL) prior structure, thereby combining QTL mapping and outlier detection into a single sparse model representation problem. The EBL priors on the mean-shift terms prevent outlying phenotypic values from distorting the genotype-phenotype association and allow their detection as cases with outstanding mean shift values following the LASSO shrinkage. Simulation results demonstrate the effectiveness of our new methodology at mapping QTLs in the presence of outlying phenotypic values and simultaneously identifying the potential outliers, while maintaining a comparable performance to the standard EBL on outlier-free data.

Published: February 2020

AbstractA comprehensive theoretical investigation validated by the measurement is necessary to assess the impact of a microgrid on the electric distribution system. Some key parameters worth investigating are- enhancing economy, reliability, quality, and resiliency of a microgrid. Considering this necessity, a study of energy delivery system in a microgrid and its financial feasibility to integrate into the energy infrastructure has been presented in this paper. A campus microgrid with energy-efficient combined heat and power (CHP) natural gas-fired microturbine and photovoltaic generation has been used as a testbed to evaluate the efficiency of the power delivery. With distributed control and communication capability, this microgrid can be considered as a building block of smart grid that facilitates the inclusion of renewable and energy-efficient distributed generation. Simulation work has been performed to study the economic feasibility to integrate such microgrid into the energy grid. Several cases of remote microgrid operation have been studied to compare the best possible solution.
Utilisation of the REA-method to a Convective Drying of Apple Rings at Ambient Temperature
Authors: Spotar Sergey , Saliyeva Sayara , Kopbayev Alibek , Shildebayev Temirlan 
Published: February 2020

Abstract
This study focuses on the convective drying of apple rings by air at ambient temperature. The lumped reaction engineering approach (REA) model has been employed to determine the rate of drying for apple rings under forced convection considered as a normal processing regime. The algorithm implies origination of the activation energy curve from accurate ‘reference’ measurements of the drying rate under natural convection conditions. Mass transfer coefficients for the apple ring samples required for the model implementation were obtained in a series of experiments under natural and forced conditions. These were compared to the values of mass transfer coefficients obtained from numerical simulation using COMSOL Multiphysics® software. The study extends the application of REA for the limiting simplest case of convective drying of thick samples under ambient temperature conditions.
Der Holocaust: Kulturelles Narrativ und Heterotopie Deutschlands
Authors: Springer Matthias 
Published: February 2020

Zusammenfassung
Der Beitrag zeigt, wie die Thematik des Holocaust im Rahmen von z. B. Orientierungskursen vermittelbar ist. Dazu führt er die Konzepte der Kultur als Erzählgemeinschaften nach Müller-Funk sowie der Heterotopien als „Andere Orte“ nach Foucault in der Auseinandersetzung um die Erinnerung an den Holocaust zusammen. Der Holocaust, so die These, vergegenwärtigt sich an zahlreichen Orten des täglichen Lebens. Diese Heterotopien eröffnen Erinnerungsräume des kommunikativen Gedächtnisses, die wiederum einen Dialog mit Erinnerungssubjekten anderer kultureller Gemeinschaften ermöglichen.

Generalized locally-exact homogenization theory for evaluation of electric conductivity and resistance of multiphase materials
Authors: Wang Guannan , Chen Qiang , Gao Mengyuan , Yang Bo , Hui David 
Published: February 2020

Abstract
The locally-exact homogenization theory is further extended to investigate the homogenized and localized electric behavior of unidirectional composite and porous materials. Distinct from the classical and numerical micromechanics models, the present technique is advantageous by developing exact analytical solutions of repeating unit cells (RUC) with hexagonal and rhomboid geometries that satisfy the internal governing equations and fiber/matrix interfacial continuities in a point-wise manner. A balanced variational principle is proposed to impose the periodic boundary conditions on mirror faces of an RUC, ensuring rapid convergence of homogenized and localized responses. The present simulations are validated against the generalized Eshelby solution with electric capability and the finite-volume direct averaging micromechanics, where excellent agreements are obtained. Several micromechanical parameters are then tested of their effects on the responses of composites, such as the fiber/matrix ratio and RUC geometry. The efficiency of the theory is also proved and only a few seconds are required to generate a full set of properties and concomitant local electric fields in an uncompiled MATLAB environment. Finally, the related programs may be encapsulated with an input/output (I/O) interface such that even non-professionals can execute the programs without learning the mathematical details.

Published: February 2020

Abstract
In order to meet the increasing engineering requirements, the ultra-early strength of sulphoaluminate cement (SAC)-based materials need to be improved to achieve road repair, engineering rescue and other objectives. Graphene oxide (GO) of 0.04 wt% was incorporated into SAC mortar to prepare GO enhanced SAC mortar (GO-SAC). It was found that the compressive strength of GO-SAC was increased by 46.9% at the age of 6 hours, and the flexural strength of GO-SAC was increased by 121.4% at the age of 100 minutes, compared with the control SAC mortar. The mechanism analysis based on the characterization results derived from XRD, BET, in situ ATR-FTIR, hydration heat measurement, TG–DSC and SEM showed that, the addition of minute quantities of GO led to the formation and growth of ribbon-like AFt,which further resulted in the improvement of the ultra-early strength of GO-SAC. This work indicates that GO has great potential for practical application in the preparation of high-performance SAC-based materials with ultra-early strength.
The grotesque knot of the symptom: Heterogeneity and mutability
Authors: Veisi Hasar Rahman 
Published: February 2020

AbstractThe present paper aims to shed light on some post-oedipal moments of the Freudian-Lacanian psychoanalysis. Going beyond the stereotypical opposition between the oedipal psychoanalysis and the anti-oedipal schizoanalysis, it endeavors to reinvestigate the semiotic nature of theknotenpunktand thesinthomeby applying some Deleuzian and Bakhtinian concepts. Thus, theknotenpunktis described as a grotesque knot bringing together some heterogeneous elements. The involved disparate components establish a rhizomatic multiplicity irreducible to a common determiner. As far as thesinthomeis concerned, it is also illustrated as a grotesque knot quilting the disseminated heterogeneous orders. In contrast to the dominant conception of the symptom with a complex mode of signifying (that is mainly bound to the oedipal topography), theknotenpunktand thesinthomehold a kind of hyper-formative mode of signifying. As a result, the latter may be regarded as pure formators irreducible to a meaning or a certain interpretation. Finally, the paper sets out to analyze and evaluate the relationship between thesinthomeand the foreclosure from a semiotic perspective. Accordingly, thesinthomeis explained as a reply to foreclosure which is specifically a perceptive-imperative (retroactive) contemplation (in the light of law according to the Peircean phaneroscopy) on the rhizomatic multiplicity of psychosis (the case of schizophrenia).
