Improved mechanical and viscoelastic properties of CNT-composites fabricated using an innovative ultrasonic dual mixing technique
Authors: Kundalwal Shailesh I. , Rathi Ankit 
Published: September 2020

Abstract
Carbon nanotube (CNT) acts as the most promising nanofiller due to its high aspect ratio and exceptional nanoscale-level properties. However, the dispersibility of CNTs in the conventional polymer matrices is a very critical issue in developing the high-strength and light-weight polymer-based nanocomposites. In this study, an attempt was made to develop cluster-free and uniform dispersion of multiwalled carbon nanotubes (MWCNTs) in the epoxy matrix using an innovative ultrasonic dual mixing technique. The effect of dispersion of MWCNTs on the mechanical and viscoelastic properties of MWCNT-epoxy nanocomposites was comprehensively studied. Our results reveal that the tensile strength and toughness of epoxy nanocomposites with 0.50 wt.% of MWCNTs improved by 21% and 46%, respectively, as compared to neat epoxy. The nanocomposite samples with the same CNT loading show maximum enhancements of 22% and 26% in the lap shear strength and storage modulus, respectively. The tensile fracture surface examination of MWCNT-epoxy nanocomposites using field emission scanning electron microscopy indicated the cluster-free and uniform dispersion of MWC-NTs in the epoxy matrix.

Published: September 2020

Abstract
Based on an irreversible quantum Carnot heat pump model in which spin-1/2 systems are used as working substance, an exergy-based ecological function and some other important parameters of the model heat pump are derived. Numerical examples are provided to investigate its ecological performance characteristics. The influences of various irreversibility factors on the ecological performance are discussed. Performance comparison and discussion among maximum points of ecological function, heating load, and so on, are conducted. At last, three special cases are discussed.
A retrospective analysis of congenital anomalies in congenital hypothyroidism
Authors: Mazahir Fatima Ali , Khadora Manal Mustafa 
Published: September 2020

Abstract

Objectives
We evaluated the spectrum of diseases accompanying congenital hypothyroidism (CH) in the United Arab Emirates and compared them with internationally studied patterns.

Methods
The presented retrospective cross-sectional study took place in two government tertiary care centres. In total, 204 patients with a confirmed diagnosis of CH and a minimum period of follow-up of 1 year were included. Patients with Down syndrome, infants born at <35 weeks of gestation, and babies with TORCH (Toxoplasma gondii, Other viruses [HIV, measles, etc.], Rubella, Cytomegalovirus, and Herpes simplex) infections were subsequently excluded from the study.

Results
Of the subjects with CH, 39% had associated extrathyroidal anomalies (ETAs); among these, 25% had a single anomaly. A significant proportion of Arab males were affected by CH as compared to other ethnic groups. Dyshormonogenesis was the commonest aetiological cause (55%) of CH. Males with an ectopic lingual thyroid gland had significant ETAs as compared to females of the same cohort. The most common ETAs were congenital heart disease (16%), followed by urogenital tract anomalies (14%).

Conclusions
Detection of a high rate and variability of ETAs associated with CH necessitates the formulation of a structured screening programme including appropriate clinical, laboratory, and imaging tools to detect ETAs at an earlier stage.
Measuring spatial allocative efficiency in basketball
Authors: Sandholtz Nathan , Mortensen Jacob , Bornn Luke 
Published: September 2020

Abstract
Every shot in basketball has an opportunity cost; one player’s shot eliminates all potential opportunities from their teammates for that play. For this reason, player-shot efficiency should ultimately be considered relative to the lineup. This aspect of efficiency—the optimal way to allocate shots within a lineup—is the focus of our paper. Allocative efficiency should be considered in a spatial context since the distribution of shot attempts within a lineup is highly dependent on court location. We propose a new metric for spatial allocative efficiency by comparing a player’s field goal percentage (FG%) to their field goal attempt (FGA) rate in context of both their four teammates on the court and the spatial distribution of their shots. Leveraging publicly available data provided by the National Basketball Association (NBA), we estimate player FG% at every location in the offensive half court using a Bayesian hierarchical model. Then, by ordering a lineup’s estimated FG%s and pairing these rankings with the lineup’s empirical FGA rate rankings, we detect areas where the lineup exhibits inefficient shot allocation. Lastly, we analyze the impact that sub-optimal shot allocation has on a team’s overall offensive potential, demonstrating that inefficient shot allocation correlates with reduced scoring.
Zur Rolle der Freiheit in Kants (Moral-)Philosophie
Authors: Geismann Georg 
Published: September 2020

AbstractThe focus of this paper is on the concepts of practical and transcendental freedom, their relation to each other, and their role in Kant’s (moral) philosophy. It is argued that there is in this regard neither an inconsistency or contradiction between the Dialectic and the Canon of the first Critique nor a break between the first and the second Critique. The Canon’s claim that we cognize practical freedom through experience must by no means be understood as implying that Kant held a “naturalized” concept of freedom. The paper also reveals the preparatory role of the first Critique with respect to the moral philosophy that Kant, beginning in the Groundwork, presented in the following years.
Durkheim’s French Neo-Kantian Social Thought: Epistemology, Sociology of Knowledge, and Morality inThe Elementary Forms of Religious Life
Authors: Garlitz Dustin 
Published: September 2020

AbstractThis article presents Durkheim as a Neo-Kantian social thinker and a source of the theory of emotional contagion.The Elementary Forms of Religious Lifeis examined as Durkheim’s paradigm case of Neo-Kantianism. He is first considered among the intellectual context of French Neo-Kantianism and its figures Charles Renouvier, Émile Boutroux, and Octave Hamelin, all whom were influential in his formative years. Durkheim’s Neo-Kantianism inThe Elementary Forms of Religious Lifeis then juxtaposed to the Neo-Kantian legal philosophy of Emil Lask and Hans Kelsen. Agued is that Durkheim’s notions of distortion and emotional contagion are his leading contributions to Neo-Kantianism.
Cassirer and Kant on the Unity of Space and the Role of Imagination
Authors: de Sá Pereira Roberto Horácio 
Published: September 2020

Abstract
The focus of this paper is Cassirer’s Neo-Kantian reading of Kant’s conception of unity of space. Cassirer’s neo-Kantian reading is largely in conformity with the mainstream of intellectualist Kant-scholars, which is unsurprising, given his own intellectualist view of space and perception and his rejection of the existence of a ‘merely sensory consciousness’ as a ‘formless mass of impression’. I argue against Cassirer’s reading by relying on a Kantian distinction first recognized by Heinrich Rickert, a neo-Kantian from the Southwest school, between Kenntnis (roughly knowledge by acquaintance) and Erkenntnis (roughly propositional knowledge). Correspondingly, I claim that concepts and categories are conditions for Erkenntnis of objects as such, namely for thinking of and apprehending the pre-existing unity as an object, rather than for the ‘constitution’ of this very unity.

Published: September 2020

Abstract
Platelet transfusion is a topic of common interest for many specialists involved in patient care, from laboratory staff to clinical physicians. Various aspects make this type of transfusion different from those of other blood components. In this review, the challenges in platelet transfusion practice that are relevant for laboratory colleagues will be discussed, highlighting how the biochemical and structural characteristics of these blood elements directly affect their function and consequently the clinical outcome. More than 1,300 platelet concentrates are transfused in Germany every day, and several types are offered by their respective manufacturers. We describe the technological advances in platelet concentrate production, with a focus on how the storage conditions of platelets can be improved. Laboratory quality assessment procedures for a safe transfusion are discussed in detail. For this purpose, we will refer to the Hemotherapy Directives (Richtlinie Hämotherapie) of the German Medical Association.

Authors: Yin Jinying , Han Jiangyue , Qi Caihui , Wang Yan 
Published: September 2020

Abstract
To explore the spectral radiation characteristics of carbon nanofibers, a finite-difference time-domain method has been applied to study and calculate the scattering/absorption factors of carbon nanofibers with various arrangements, while the filler contents are 61.15%, 53.81%, 48.92%, 44.03% and 39.13% in the spectrum band of 2.5–15 µm. The effects of the nanofiber content, 2D/3D random arrangement and nanofiber radius on scattering/absorption characteristics have been analyzed. The analytical results show that the spectral radiation characteristics of carbon nanofibers have been significantly increased with an increase in the filler content. When the nanofiber content reduced to 48.92%, the random arrangement structure of carbon nanofiber plays an essential role in determining the spectral radiation characteristics. Analytical results prove that the prediction accuracy has been significantly improved by 30.12% by sing the 3D random arrangement model than by using the 2D uniform arrangement model. This study proposed a 3D model to predict the spectral radiation characteristics of carbon nanofibers and their aggregates in engineering nanocomposites.

Published: September 2020

Abstract
Functionalized graphene-based nanocomposites have opened new windows to address some challenges for increasing the sensitivity, accuracy and functionality of biosensors. Polyaniline (PANI) is one of the most potentially promising and technologically important conducting polymers, which brings together the electrical features of metals with intriguing properties of plastics including facile processing and controllable chemical and physical properties. PANI/graphene nanocomposites have attracted intense interest in various fields due to unique physicochemical properties including high conductivity, facile preparation and intriguing redox behavior. In this article, a functionalized graphene-grafted nanostructured PANI nanocomposite was applied for determining the ascorbic acid (AA) level. A significant current response was observed after treating the electrode surface with methacrylated graphene oxide (MeGO)/PANI nanocomposite. The amperometric responses showed a robust linear range of 8–5,000 µM and detection limit of 2 µM (N = 5). Excellent sensor selectivity was demonstrated in the presence of electroactive components interfering species, commonly found in real serum samples. This sensor is a promising candidate for rapid and selective determination of AA.
The Problem of Reality and Modal Ontology
Authors: Šerpytytė Rita 
Published: September 2020

Abstract
The problem of the relation and difference between things and objects is one of the most decisive issues for the conception of the real. These words are usually used interchangeably – and not only in their everyday usage. There are some contemporary philosophical positions that consider almost “everything” as an object; on the other hand, there are proponents of a strict separation of objects and things. How did it happen that the concept of thing (res) and object (obiectum) not only began to theoretically “compete” with each other but also sometimes came to represent differently conceived realities, and even occasionally came to represent an identical conception of reality? This article, on the one hand, discusses the philosophical strategies that reveal the difference between objects and things and enable such a conception of reality which takes into account the Kantian distinction between Realität and Wirklichkeit. On the other, it reconstructs Giorgio Agamben’s project of modal ontology. Agamben’s take on the question What is real? is oriented toward the modus of being and could be traced back to the recognition of the difference between objects and things as well as the “restoration of the life of things themselves.”

Authors: Zhu Yisong , Wu Zhenjun , Xie Xiuqiang , Zhang Nan 
Published: September 2020

Abstract
MXene with two-dimensional layered structure and desirable electronic properties has emerged as a promising candidate to construct MXene-based composites towards various photocatalytic applications. As compared to the downhill-type photodegradation reactions, artificial photosynthesis often involves thermodynamic uphill reactions with a large positive change in Gibbs free energy. Recent years have witnessed the effectiveness of MXene in enhancing the photoactivity of MXene-based composites for solar fuel synthesis. In this review, we mainly focus on the applications of MXene-based composites for photocatalytic solar fuel production. We will start from summarizing the general synthesis of MXene-based composite photocatalysts. Then the recent progress on MXene-based composite photocatalysts for solar fuel synthesis, including water splitting for H2 production, CO2 reduction to solar fuels, and N2 fixation for NH3 synthesis is elucidated. The roles of MXene playing in improving the photoactivity of MXene-based composites in these applications have also been discussed. In the last section, perspectives on the future research directions of MXene-based composites towards the applications of artificial photosynthesis are presented.

Abstract
Increasing demands to obtain chemicals via greener and more sustainable materials and processes introduces concepts that should be considered and applied from lab to larger scales. Obtaining bioactive chemicals from agro-industrial non-food biomass waste can combine benign techniques and bio-circular economy to reach this goal. After extraction, evaluating profitability and environmental impacts to decide whether separation – and to what extent – is necessary or not is indispensable. This could be integrated into an approach known as sufficiency, as an important criterion for sustainability. From this perspective, Brazil’s annual generation of 8 million tons of orange waste is relevant, since citrus waste has large amounts of high-value compounds, such as pectin, d-limonene and flavonoids. This case study aimed at developing and comparing green and sustainable analytical methods to obtain flavonoids from orange peel. Homogenizer, ultrasound and microwave-assisted extractions were employed using chemometric tools, considering time, sample/solvent ratio, temperature and ethanol concentration as variables to obtain extracts containing hesperidin, naringenin, hesperetin and nobiletin. The bioactive flavonoids were determined by high-performance liquid chromatography (HPLC-UV). Microwave extraction was the most efficient method for obtaining the majority of flavonoids studied, six times more for hesperidin. Moreover, orange waste from different farming models showed diverse chemical profiles showing the importance of this alternative in natural product resources.
Experimental set up for magnetomechanical measurements with a closed flux path sample
Authors: El Youssef Mohamad , Van Gorp Adrien , Clenet Stéphane , Benabou Abdelkader , Faverolle Pierre , Mipo Jean-Claude 
Published: September 2020

AbstractIn this article, an experimental procedure is presented to handle magnetic measurements under uniaxial tensile stress reaching the plastic domain. The main advantage of the proposed procedure is that it does not require an additional magnetic core to close the magnetic flux path through the studied sample. The flux flows only in the sample, and no parasitic air gaps are introduced, thus avoiding the use of the H-coil to evaluate the magnetic field, which is often very sensitive and not easy to calibrate. A specimen of nonoriented FeSi (1.3%) sheet (M330-35A) is characterized under uniaxial tensile stress. To validate the proposed procedure, a comparison with the single sheet tester procedure is carried out. The results obtained by the two procedures are in good agreement. Moreover, to illustrate the possibilities offered by the proposed procedure, we confirm some results obtained in the literature. We show that the positive plastic strain leads to a significant degradation of magnetic behavior. An applied tensile stress on a virgin (unstrained) sample leads to a degradation of the magnetic behavior. However, on a pre-strained sample, an applied tensile stress results in reducing the deterioration caused by the plastic strain until a stress value called optimum is attained. Above this threshold, the magnetic behavior re-deteriorates progressively.

A Welfare Assessment of Revenue Management Systems
Authors: Dupuis Nicolas , Ivaldi Marc , Pouyet Jerome 
Published: September 2020

AbstractWe study the welfare impact of revenue management, a practice which is widely spread in the transport industry, but whose impact on consumer surplus remains unclear. We develop a theoretical model of revenue management allowing for heterogeneity in product characteristics, capacity constraints, consumer preferences, and probabilities of arrival. We also introduce dynamic competition between revenue managers. We solve this model computationally and recover the optimal pricing strategies. We find that revenue management is generally welfare enhancing as it raises the number of sales.

Die klassische Tradition in der russischen Literatur: zum Problem ihrer Genesis
Authors: Bucharkin Petr E. 
Published: September 2020

Summary
The article considers the poetry of S. S. Averintsev. The analysis of its dominating thematic, generic and verse features allows us to see in this poetry a peculiar development of literary trends of the late 17th/early 18th centuries, which were connected with the transformation of autochthonous artistic sources and generated a whole range of original texts, including poetic ones (“Povest’ o Gore-Zlochastii”, Songs of P. Kvashnin-Samarin). On the basis of another historic correlation Averintsev’s poetry can be considered an attempt to present the classical tradition of Russian literature as a direct development of medieval verbal principles in their Moscow variant. This position was supported by the scholar’s philological conceptions and was also confirmed by the statements of a number of literary critics, as well as by the poetic practice of Olga Sedakova, which was close to that of Averintsev. The article explores the correlation of these perceptions with historical and literary facts.
Teodor Trajanov als Vermittler zwischen der Wiener und der bulgarischen Moderne
Authors: Vlashki Mladen 
Published: September 2020

SummaryThe study is looking into the first creative period of the Bulgarian poet Teodor Trajanov based on his newly rediscovered works. They allow the description of the author as a conscious mediator between the Viennese and the Bulgarian modernity, who imports himself in the vernacular Bulgarian literary environment as a “modern poet” from Vienna. For the first time, the analysis discovers actual connections between the poetry of Trajanov and the specifics of the Viennese modernity as a cultural environment. On the basis of critical texts from the author, his views on modern works are described and defined in the spirit of the age as “decadent”. Trajanov is also the only Bulgarian literary figure, who fits the processes of the late Viennese modernism with his screenplay for a play in the Viennese Volksoper from 1914. The text considered lost by Trajanov researchers has been presented for the first time after its discovery by the author of the article, with the required contextual reconstruction. Here, the mediatory role of the poet between two modern European cultures of the beginning of the 20th century, as well as new perspectives not only for the exploration of Trajanov’s poetry but also for reconsidering the inception of the Bulgarian modernism, are considered.
