Structural, electrical and magnetic properties of glucose-capped CdS nanoparticles
Authors: Kumar S. , Sharma J. K. , Sharma S. K. , Dhupar A. , Sharma V. , Gaur A. 
Published: February 2021

Abstract
CdS nanoparticles are synthesized by a simple chemical coprecipitation technique using glucose as a capping/complexing agent and their structural, morphological, electrical and magnetic properties are studied. X-ray diffraction results reveal the pure phase formation of CdS nanoparticles along with a wurtzite structure. The interaction of the glucose with CdS nanoparticles is evident from the distinct absorption bands and peaks in the Fourier transform infrared spectra. Field effect scanning electron microscope and high resolution transmission electron microscope images depict weakly aggregated spherical nanoparticles of size ~2- 20 nm. The selective area electron diffraction pattern exhibits well-resolved diffraction rings representing the polycrystalline nature of the nanoparticles. The optical band gap has been calculated using Tauc’s plot and found to be 2.58 eV, which is higher than the band gap of the bulk phase wurtzite CdS. The existence of the excitonic peak and the blue-shift in the absorption threshold confirm the quantum confinement in the synthesized nanoparticles. The temperature dependence of d. c. conductivity is studied and observed a linear response through current-voltage characteristics. Weak ferromagnetism is also observed in the synthesized CdS nanoparticles irrespective of the diamagnetic nature of CdS in bulk form. The observation of weak ferromagnetism in the synthesized nanoparticles proposes them as a potential candidate for diluted magnetic semiconductors.
Microstructure and texture of Ti-6Al-4V alloy deformed by rotary forging at elevated temperatures
Authors: Jiang Shan 
Published: February 2021

Abstract
Ti-6Al-4V alloy cylinder samples were subjected to rotary forging at temperatures ranging from room temperature to 1 473 K. The microstructure and texture were examined by means of electron back-scatter diffraction and X-ray diffraction. The results indicated that the rotary forging could remarkably promote formability at elevated temperatures but not room temperature. For the 1 073 K and 1173 K samples, dynamic recrystallization led to a notable grain refinement effect and produced a typical basal texture. With the further increase of deforming temperature to 1 473 K, dislocation slip contributed the main deformation and the effect of grain refinement was weakened. The martensitic transformation took place during the cooling process of the 1 473 K sample, forming a strip type microstructure and a special texture different from basal texture.
Borocarbide coarsening and the effect of borocarbide particle size on Charpy V-notch impact properties of medium-carbon boron-containing steel

Published: February 2021

Abstract
Boron-added steel has been used in several automotive components in which the energy absorbed in impact testing is an important requirement. Previous thermodynamic studies have shown that boron addition promotes significant change in equilibrium phases, increasing the volume fraction of precipitated phases, mostly due to increased carbide stability and formation of borocarbides. As volume fraction, size and distribution of precipitates influence the absorbed energy in impact testing of steels, it is important to study M23(B,C)6 borocarbide precipitation and coarsening kinetics and its effects on Charpy V-notch absorbed energy of boron steels. In the present work, borocarbide coarsening kinetics were evaluated using optical microscopy in samples heat-treated at 880 0C for different times. The borocarbide coarsening kinetics data suggest that growth is controlled by an interfacial reaction mechanism. The Charpy V-notch absorbed energy decreases with increasing borocarbide section size and the embrittlement was successfully described by an empirical equation.
Study of the crystallization kinetics of a Zr57Cu15.4Ni12.6Al10Nb5 amorphous alloy
Authors: Hu Hui E. , Lu Zhou , Hong Su Xiao , Xin Deng Jing 
Published: February 2021

Abstract
The non-isothermal crystallization kinetics with heating rates ranging from 10 K s-1to 80 K s-1and the isothermal crystallization kinetics during annealing from the glass transition temperature to the crystallization onset temperature of a Zr57Cu15.4Ni12.6Al10Nb5 amorphous alloy were studied in detail using X-ray diffraction and differential scanning calorimetry. During non-isothermal crystallization, it is more difficult to nucleate than to grow, and the crystallization resistance increases first and then decreases. During isothermal crystallization of the alloy from 713- 728 K, there are two exothermic peaks corresponding to a diffusion-controlled growth process with decreasing nucleation rate and increasing nucleation rate. From 733- 748 K, only one exothermic peak appears, and the growth process is controlled by the interface with decreasing nucleation rate. Isothermal crystallization is a process in which the crystallization resistance increases. The resistance of isothermal crystallization is less than that of non-isothermal crystallization.
Accelerated degradation rate of high-strength Mg-4Y-1Zn alloy by Cu addition for degradable bridge-plug applications
Authors: Liu Baosheng , Dong Gehang , Ren Xiaoxia , Zhang Yuezhong , Wei Yinghui 
Published: February 2021

Abstract
To find good candidate materials for degradable bridgeplugs used in shale oil or gas exploitation, a novel hot extruded Mg-4Y-1Zn-1Cu alloy with long period stacking order (LPSO) phase and excellent mechanical properties and rapid degradation rate was fabricated. Compared with the Mg-4Y-1Zn alloy, the compressive properties of Mg-4Y- 1Zn-1Cu alloy are dramatically enhanced by adding Cu, with a compressive strength of 480 MPa, which can be attributed to the formation of fine-grains and the strengthening LPSO phase distributed within the substrate. Furthermore, Mg-4Y-1Zn-1Cu alloy shows a rapid degradation rate as demonstrated by immersion tests and polarization curves, with about 30 times higher corrosion rate than Mg- 4Y-1Zn alloy, which can be attributed to the 14H-type LPSO phase containing Cu with high corrosion potential and high fraction grain boundaries.
Existence of positive periodic solutions for a class of second-order neutral functional differential equations
Authors: Yang He , Zhang Lu 
Published: February 2021

Abstract
In this paper, under some ordered conditions, we investigate the existence of positive ω-periodic solutions for a class of second-order neutral functional differential equations with delayed derivative in nonlinearity of the form (x(t) − cx(t − δ))″ + a(t)g(x(t))x(t) = λb(t)f(t, x(t), x(t − τ
1(t)), x′(t − τ
2(t))). By utilizing the perturbation method of a positive operator and the fixed point index theory in cones, some sufficient conditions are established for the existence as well as the non-existence of positive ω-periodic solutions.
Spirituality, Administration, and Normativity in Current Church Organization
Authors: Ershova Maria , Hermelink Jan 
Published: February 2021

Abstract
The paper addresses issues regarding the current balance between spirituality and administration in different church denominations using an interdisciplinary approach which combines management science and theology. It presents a comparative study of organizational culture of the Roman Catholic Church, a Lutheran church, and a Reformed church with the use of the questionnaire based on the Competing Values Framework (Cameron/Quinn) and qualitative interviews with leading persons in church.
The authors discuss the findings from two different but complementary perspectives: in relation to the four types of organizational cultures in the Cameron/Quinn framework, and as a result of the specific denominational semantics represented in the questionnaire used for the study. The results show how the question of modernity is reflected in organizational culture of churches, and how deeply the respondents’ perception of church is influenced by inherent normativity. One of the central conclusions is that religiously rooted normativity serves as an instrument of balancing the administrative and the spiritual in church.
Christian Mission and Ministry in the Context of Contemporary Migration
Authors: Cruz Gemma Tulud 
Published: February 2021

Abstract
The twenty-first-century saw the considerable rise of the movement of peoples largely due to the structures and processes of globalization. The gifts and challenges associated with the massive flow of people on the move, almost half of whom are Christians, constitute a locus for exploring Christian mission and ministry. The following text explores some of the faces of Christian mission and ministry as a result of, or in response to, the gifts and challenges posed by contemporary human mobility. The text shows how an authentically inclusive church that works for justice, particularly for the most vulnerable migrants, constitutes the key expression of Christian mission and ministry in the context of global migration.
Polysemy and the Semantic-pragmatic Interface: The Case ofUpin a Context-based Model
Authors: Lu Wei-Lun 
Published: February 2021

AbstractThe present study adopts a context-based approach to the meaning ofup. The analysis draws on the notion of “context” defined as a composite of surrounding linguistic cues, world knowledge and physical environment of the utterance, and on a parsimonious criterion of sense establishment. I demonstrate that the proposed model is capable of distinguishing context-sensitive implicatures and senses, with only two separate senses listed: “vertically higher” and “completive”. I propose a developmental hierarchy in the meaning network that refines Hampe’s (2005. Whendownis not bad, andupnot good enough: A usage-based assessment of the plus-minus parameter in image-schema theory.Cognitive Linguistics16(1). 81–112) challenge to the axiological parameter by unhooking “completive” from “good”. The proposed model finally addresses cases of seeming oxymora to explicate the context-sensitivity of interpretations. The paper concludes with a two-fold implication: first, the context-oriented methodology is capable of distinguishing context-induced implicatures and context-insensitive senses. Second, it captures the details of lexical meaning as contextualization patterns by explicating how the prototypical sense of a spatial particle, undergoing the fine-tuning of linguistic, encyclopedic and physical context, derives diverse contextual implicatures in real use.
The PRO-VOC method: Combining pronunciation and vocabulary teaching
Authors: Nicolaidis Katerina , Mattheoudakis Marina 
Published: February 2021

Abstract
This paper proposes a new method for the combined teaching of pronunciation and vocabulary to learners of English as a foreign language (EFL). While there is commonly strong emphasis on the teaching of vocabulary, pronunciation teaching is frequently neglected in the EFL classroom. The proposed method aims to address such imbalance which may affect learners' general fluency skills, degree of intelligibility and communicative competence. The paper provides a detailed account of the new method which argues in favour of organising new vocabulary according to some aspect of the phonological form of the word. It discusses the major principles the method is founded upon (i.e., categorisation and selected learning strategies) and presents two examples to illustrate its application. Finally, it elaborates on the potential advantages this method may have for the acquisition of pronunciation and vocabulary and presents the major procedural steps the teacher can follow when implementing this method.
An investigation into the relationship of foreign language learning motivation and sign language use among Deaf and hard of hearing Hungarians
Authors: Kontra Edit H. , Csizér Kata 
Published: February 2021

Abstract
The aim of this study is to point out the relationship between foreign language learning motivation and sign language use among hearing impaired Hungarians. In the article we concentrate on two main issues: first, to what extent hearing impaired people are motivated to learn foreign languages in a European context; second, to what extent sign language use in the classroom as well as outside school shapes their level of motivation. The participants in our research were 331 Deaf and hard of hearing people from all over Hungary. The instrument of data collection was a standardized questionnaire. Our results support the notion that sign language use helps foreign language learning. Based on the findings, we can conclude that there is indeed no justification for further neglecting the needs of Deaf and hard of hearing people as foreign language learners and that their claim for equal opportunities in language learning is substantiated.
Investitionsverhalten und Liquiditätsrestringiertheit. Eine Sensitivitätsanalyse / Investment Behaviour and Liquidity Constraints. A Sensitivity Analysis
Authors: Behr Andreas , Bellgardt Egon 
Published: February 2021

Zusammenfassung
In verschiedenen empirischen Arbeiten wird für a priori als nicht liquiditätsrestringiert klassifizierte Unternehmen ein signifikant geringerer Einfluß des Cash Flow auf die Investitionstätigkeit festgestellt. In diesem Artikel wird der Frage nach der Sensitivität dieser Befunde in verschiedener Hinsicht nachgegangen. Es werden drei unterschiedliche Operationalisierungen von Tobins Q vorgenommen sowie vier alternative a priori-Klassifikationsvariablen als Indikatoren zur Messung der Liquiditätsrestringiertheit berücksichtigt. Zudem wird die Sensitivität der Ergebnisse bezüglich der verwendeten Klassengrenzen untersucht. Für drei der vier untersuchten Klassifikationsvariablen zeigt sich, daß die als a priori nicht liquiditätsrestringiert eingestuften Sektorjahre einen signifikant geringeren Einfluß des Cash Flow auf die Investitionstätigkeit aufweisen. Zudem zeigt sich eine relativ geringe Sensitivität der Ergebnisse bezüglich der gewählten Klassifikationsgrenzen. Die Operationalisierung von Tobins Q als Renditequotient führt - im Vergleich zu der auf Bestandsgrößen beruhenden - zu weniger signifikanten Ergebnissen.
Henry James’s “The Jolly Corner”1: Revisiting the Parable of the Prodigal Son (Luke 15:11–32)
Authors: Jack Alison 
Published: February 2021

Abstract
In this article, various reception-historical analyses of Henry James’s short story “The Jolly Corner” and its use of the Bible are subjected to critique. The parable of the Prodigal Son is offered as a convincing and significant intertext which is clearly signalled in the story. Reading this parable in the narrative yields useful insights into the dynamics between the characters, and suggests a psychological rather than supernatural interpretation of events.
“Gar nicht biblisch!” [Not biblical at all!]: Ephesians, Marriage, and Radical Pietism in Eighteenth-Century Germany
Authors: Petterson Christina 
Published: February 2021

Abstract
This article explores the use of Ephesians 5 and the church as the bride of Christ within a set of 18th-century speeches to the married couples in a radical pietist community known as the Moravian Brethren. I will show how the text is used to undergird a novel ideology of marriage and community structure, both of which are connected with socio-economic change.

Abstract
In this paper, we will study, via
simulation, the transmission of DVB-C channels
over an external modulated optical link using
a Mach-Zehnder modulator (MZM). We will also
observe the consequences of biasing the MZM
near its transmission minimum point, which
allows higher carrier to noise ratio at the
transmitter, but increases second-order
distortion at the receiver.

Abstract

Background
Thyroid function in children with leukemia during the first year after hematopoietic stem cell transplantation (HSCT) was investigated.

Methods
The medical records of 186 subjects [111 boys and 75 girls; lymphoid=75, myeloid=111; median age at HSCT was 10.7 (0.8–21.8) years old] were reviewed retrospectively.

Results
In children with leukemia, T3 decreased at 1 month (p<0.001) and recovered 9 months to the levels before HSCT. TSH decreased at 1 month (p<0.001), recovered at 3 months and increased at 12 months (p<0.001) to the levels before HSCT. The incidence of euthyroid sick syndrome (ESS, 23.2%, 15.5%, 5.9%, 5.2%, 3.9%, p for trend <0.001) decreased and subclinical hypothyroidism (SH, 0%, 3.9%, 14.8%, 22.1%, 21.3%, p for trend <0.001) increased at 1, 3, 6, 9 and 12 months after HSCT. Out of 55 patients developing ESS during 3 months after HSCT, 54 recovered to normal thyroid function within 5 months without medication. Among the total 186 subjects, 21 patients have been treated with levothyroxine. Both height and weight standard deviation scores continued to decrease over 1 year after HSCT.

Conclusions
In children with leukemia, one-quarter had ESS at 1 month and one-fifth had SH at 12 months and continued growth impairments were observed during 1 year after HSCT. Most of the ESS patients recovered to normal within 5 months without medication. More long-term follow-up of thyroid function and growth in children with leukemia after HSCT is crucial.
On the Latin Transcription of Hebrew and Aramaic Proper Names in the Latin Talmud (Tractate Sanhedrin). Phonetic Features of the Translation
Authors: Vernet i Pons Eulàlia 
Published: February 2021

Abstract
The aim of this paper is to provide a linguistic and onomastic description of the proper names and other Hebrew biblical realia transcribed and translated into Latin in the Talmudic tractate of Sanhedrin (thirteenth century). The Latin translation of Sanhedrin is a part of the Talmudic corpus known as Extractiones de Talmud; it is the largest Latin translation of the Talmud and was produced in Paris by Christian theologians in the 1240s. While the Extractiones are a quite exhaustive translation of the Talmud, they are not complete, but offer a selection of different Talmudic tractates that were of theological interest in order to strengthen the Christian faith in a context of anti-Jewish polemic. An onomastic approach to the Latin Sanhedrin will allow us to describe philologically the Hebrew words underlying the Latin transcription. It will also give us information about the criteria of transcription followed by the Latin translators of the Talmud.
Saracens and Turks in William Caxton’s The Golden Legend
Authors: Ford Judy A. 
Published: February 2021

Abstract
In the late fifteenth century, William Caxton translated into English and published a version of the best-known collection of saints’ lives in medieval Europe, the Legenda aurea. It was the longest and most expensive book he ever produced. Caxton used various sources, including Latin and French versions of the Legenda, to create a collection accessible to the book-buying public who were literate in the vernacular in late-fifteenth and early sixteenth-century England. The Golden Legend includes fifteen lives that incorporate Saracens or Turks into their narratives. It describes their interactions with Christians, both peaceful and violent, as well as their capacity for conversion. The depiction of Muslims in this popular sermon collection would have formed part of the cultural construction of Islamic people in England at the turn of the sixteenth century.
Transcendental Paralogisms as Formal Fallacies - Kant’s Refutation of Pure Rational Psychology
Authors: Kannisto Toni 
Published: February 2021

Abstract:
According to Kant, the arguments of rational psychology are formal fallacies that he calls transcendental paralogisms. It remains heavily debated whether there actually is any formal error in the inferences Kant presents: according to Grier and Allison, they are deductively invalid syllogisms, whereas Bennett, Ameriks, and Van Cleve deny that they are formal fallacies. I advance an interpretation that reconciles these extremes: transcendental paralogisms are sound in general logic but constitute formal fallacies in transcendental logic. By formalising the paralogistic inference, I will pinpoint the error as an illegitimate existential presupposition. Since - unlike transcendental logic - general logic abstracts from all objects, this error can only be detected in transcendental logic.
Der Grund der Verbindlichkeit. Mendelssohn und Kant über Evidenz in der Moralphilosophie (1762/64)
Authors: Klemme Heiner F. 
Published: February 2021

Abstract:
The paper discusses the concepts of obligation and moral evidence in Mendelssohn’s and Kant’s prize essays. I argue that Mendelssohn departs in significant ways from Christian Wolff’s position, and that Kant intends to overcome Wolffian philosophy with Newtonian methodology while still owing a lot to Wolff and to the project of an ethics within the limits of metaphysics. Although quite akin to Francis Hutcheson’s philosophy, it becomes clear that Kant intended to lay the foundation of an innovative concept of obligation, which shares some similarities with Christian August Crusius’s interpretation of it.
Beautiful Perception and its Object. Mendelssohn’s theory of mixed sentiments reconsidered
Authors: Pollok Anne 
Published: February 2021

Abstract:
Complex aesthetic perception, according to Mendelssohn’s writings between 1755 and 1771, is most alluring if it showcases a breach in the order of perfection. With this, Mendelssohn introduces a shift in our understanding of the artistic act of imitation: Artistic semblance is always lacking, and a painting that does not point to this fact is, in fact, displeasing. This is also the main reason why we enjoy non-beautiful art: in the artistic rendering of an unpleasant ‘object’ we focus on the artistic act itself, on its formal features, and its effects on us as the perceiver. Thus, a representation that evokes the mixed feelings of pleasure, appreciation, and rejection is superior to ‘pure’ beauty, in that it better refers us to higher forms of perfection: the perfection of the perceiving and creative subject (hence, including both artist and audience). It is the nagging, near-painful impression of mixed sentiments that, according to Mendelssohn, guides our self-perfection, the highest aim of all human endeavors.
Dative shift in a language without dative? The (allative) case of Finnish
Authors: Kittilä Seppo 
Published: February 2021

Abstract
Dative shift is a two-fold process that affects both the morphological coding and the order of T and R arguments of a three-participant construction, as in the teacher gave a book to the student vs. the teacher gave the student a book. Across languages, dative shift tends to express similar functions including differences in animacy, definiteness, semantic role of arguments, affectedness of recipient and permanence of transfer. This is understandable, since dative shift increases the formal transitivity of the affected clauses, and all the expressed functions are somehow related to transitivity. The goal of this paper is to study whether, and to what extent, mere changes in word order suffice to express the functions of dative shift. The examined language is Finnish, which suits very well for this purpose due to its relatively free word order and inherently different coding of Theme and Recipient. It can be hypothesized that mere word order changes readily express features related to definiteness and animacy, while they are less capable of expressing features such as affectedness of the recipient.
