Also, the main result has been already proved under “nice prime” condition by Ardakov, Wei and Zhang

Two-Phase Flow of Fluid-Particle Interaction over a Stretching Sheet in the Presence of Magnetic Field
Authors: Hasnain J. , Abbas Z. , Sajid M. 
Published: July 2019

Abstract
This article presents a theoretical study of magnetohydrodynamic boundary layer flow of a dusty viscoelastic fluid over a porous stretching sheet. The basic steady equations of the viscoelastic second grade fluid and dust phases are in the form of partial differential equations. A set of coupled nonlinear ordinary differential equations is obtained by using suitable similarity transformations. The approximate first order solutions of the resulting equations are obtained using the perturbation technique. The results are also verified with the well-known finite difference technique known as Keller box method. The physical insight of the involved parameters on the velocity of both fluid and dust phases and the skin-friction coefficient is shown through graphs and tables and discussed in detail. The study shows that an increased effective viscosity increases the velocity of both fluid and particle phase.
Approximation of p-Biharmonic Problem using WEB-Spline based Mesh-Free Method
Authors: Rajashekar Naraveni , Chaudhary Sudhakar , Srinivas Kumar V.V.K. 
Published: July 2019

Abstract
We describe and analyze the weighted extended b-spline (WEB-Spline) mesh-free finite element method for solving the p-biharmonic problem. The WEB-Spline method uses weighted extended b-splines as basis functions on regular grids and does not require any mesh generation which eliminates a difficult, time consuming preprocessing step. Accurate approximations are possible with relatively low-dimensional subspaces. We perform some numerical experiments to demonstrate the efficiency of the WEB-Spline method.
Universals and transfer in the acquisition of the progressive aspect: Evidence from L1 Chinese, German, and Spanish learners’ use of the progressive-ingin spoken English
Authors: Zeng Xiaoyan , Shirai Yasuhiro , Chen Xiaoxiang 
Published: July 2019

AbstractThis study investigated the effects of learners’ first language (L1), lexical aspect of verbs, and proficiency levels on their use of the English progressive aspect. It analyzed spoken data from learners of three different L1s (Chinese, German, and Spanish) in an international learner corpus (LINSEI), in comparison with native speech in a comparable native speaker corpus (LOCNEC). The analysis reveals that regardless of learners’ L1 and proficiency levels, their use of progressive markings is predominantly associated with activity verbs (prototypes), supporting the association prediction of the Aspect Hypothesis (Andersen, Roger W. & Yasuhiro Shirai. 1994. Discourse motivations for some cognitive acquisition principles.Studies in Second Language Acquisition16(2). 133–156). Contrary to the fourth prediction of the Aspect Hypothesis, both intermediate and advanced learners use stative progressives, and especially intermediate L1 Spanish learners overuse stative progressives, indicating a complex interaction between L1 and proficiency on non-prototypical form-meaning associations. The results suggest that L1 effect, lexical aspect of verbs, and proficiency levels jointly drive tense-aspect acquisition.

-regular if the restriction of χ to S is the character of the regular representation of S.
If, in addition, χ vanishes at all elements of order divisible by p, χ is said to be Steinberg-like.
For every finite simple group G, we determine all primes p for which G admits a Steinberg-like character, except for alternating groups in characteristic 2.
Moreover, we determine all primes for which G has a projective FG-module of dimension

Thermal rearrangement of a 1,2-bis(silylene): Synthesis and crystal structure of a silyl-silylene
Authors: Sidiropoulos Anastas , Stasch Andreas , Jones Cameron 
Published: July 2019

Abstract
Thermal rearrangement of the 1,2-bis(silylene), [{(4-ButPh)C(NDip)2}Si−]2 (Dip = 2,6-diisopropylphenyl, leads to the silyl-silylene, {(4-ButPh)C(NDip)2}Si−Si(H) {N(Dip)C(=NDip)(4-ButPh-H)}, via an intramolecular C−H activation reaction. The X-ray crystal structure, and limited spectroscopic data, for the compound are reported. The structure of the silyl-silylene incorporates an exocyclic imine fragment, which is unprecedented for this compound class.
Glossopoesis in Thomas More’s Utopia: Beyond a representation of foreignness
Authors: Noletto Israel A. C. , Lopes Sebastião Alves Teixeira 
Published: July 2019

Abstract
This paper demonstrates the premise that the Utopian language created for the narrative is more than something that only gives the impression of foreignness to the invented nation of Utopia, a mere representation of an outside culture. It is rather a semiotic system devised by the author specifically with the goal of transmitting a message. As such it is indispensable to a fuller understanding of More’s work, and therefore worthy of proper investigation. Consequently, the paper analyses the occurrences of the invented language throughout the author’s text and out of it, in Peter Giles’s writings, word by word, tracing the probable etymologies and meanings, comparing cognate or correlated words in other languages, while conciliating the use of the glossopoeia with the presumptions of semiotics. Some theorists and commentators contribute considerably to the present discussion: Culler (1981. The pursuit of signs. London: Routledge, Romm), James (1991. More’s strategy of naming in the Utopia. Sixteenth Century Journal 22(2). 173–183), Sacks (1999. Introduction to Thomas More’s Utopia. In Utopia. Boston: Bedford/St Martin’s), as well as More’s and Peter Giles’s own elicitations. The result of such reflections is a theory on the critique of the names and the artificial words coined by Thomas More.

Zusammenfassung
Im Genre des Portraits verhandelt die Kunst immer wieder neu die Frage nach dem Menschen. Als wer sich der Mensch dabei präsentiert und wie dies künstlerisch gerahmt wird, ist dabei in der Analyse solcher Kunstwerke Erkenntnis leitend. Der Artikel analysiert drei fotografische Portraitreihen, die sich nicht nur dem Individuum zuwenden, sondern dessen Entwicklung vom Kind zum Erwachsenen ästhetisch darstellen. In diese Präsentation sind zugleich Modelle der Entwicklung eingewoben, die es rekonstruktiv zu erschließen gilt. Sie nutzen dazu auf je verschiedene Art und Weise die am Menschen wahrnehmbaren Veränderungen zur Darstellung. Anhand der Arbeiten der Künstler Stefan Rehberg, Chino Otsuka und Irnia Werning werden so Theoriemodelle implizit wahrnehmbar.
RbKLi2[Li3SiO4]4:Eu2+ an ultra narrow-band phosphor
Authors: Dutzler Daniel , Seibald Markus , Baumann Dominik , Philipp Frauke , Peschke Simon , Huppertz Hubert 
Published: July 2019

Abstract
The new phosphor RbKLi2[Li3SiO4]4:Eu2+ was synthesized by different high-temperature solid-state reactions. It is accessible from the alkali metal carbonates, SiO2, and Eu2+ as a luminous active cation either in closed tantalum ampoules or by conventional solid-state reaction in nickel crucibles, under a constant flow of forming gas. The structure of the thereby received rod-shaped crystals was solved and refined on the basis of single crystal X-ray diffraction data. The compound crystallizes isostructurally to CsKNa2[Li3SiO4]4 and forms a highly condensed network of LiO4 and SiO4 tetrahedra [I4/m (no. 87), Z = 2, a = 10.9508(6) and c = 6.3334(3) Å]. It is a new member of the recently discovered family of alkali lithosilicate phosphors. Under excitation with UV to blue light, the compound exhibits interesting luminescence properties. Depending on the mode of synthesis, either green or blue luminescence of the samples is observed. Both emission profiles can be described as ultra-narrow-banded, since the full width at half maximum (fwhm) is below 0.2 eV. The green phosphor shows an emission maximum at 532 nm with a fwhm of 43.5 nm (0.193 eV) and the blue one at 474 nm with a fwhm of 24.8 nm (0.137 eV). Furthermore, the material presented here allows a more detailed localization of the luminescence center inside the structure, which may allow a better understanding of the luminescence properties of many other alkali lithosilicate phosphors.
Estetik diş hekimliğinde renk seçimi
Authors: SENGEZ Görkem , DÖRTER Can 
Published: July 2019

Günümüzde ilerleyen teknoloji ile birlikte hastalar diş
hekimine sıklıkla estetik restorasyonlar için başvurmaktadır. Diş hekimlerinin
hastalara estetik bir görüntü sunabilmek için yapılacak restorasyonda dikkat
edilmesi gereken en önemli unsurlardan biri renktir. Rengin bağlı olduğu üç
faktör vardır; gözlemci, obje ve ışık kaynağı. Bu üç faktörden herhangi biri
değişirse, rengin algılanması da değişir. Rengin özelliklerini anlatmak için çeşitli sistemler
geliştirilmiştir. Munsell Renk Sistemi en çok kullanılan sistemlerdendir. Bu
sistemde rengin hue, value ve chroma olmak üzere üç boyutu bulunmaktadır. Hue
rengin kendisini (yeşil, kırmızı, mavi gibi), value parlaklığını, chroma ise
yoğunluğunu ifade eder. CIELab ise rengi L*,a*,b* olarak üç eksende tanımlayan
başka bir sistemdir.Renk seçimi görsel ve aletli renk seçimi olmak üzere ikiye
ayrılır. Diş hekimleri hastaları için en uygun diş rengini seçmeli ve bu
bulguyu teknisyene doğru aktarmalıdır. Görsel renk seçiminde renk skalaları kullanılır.
Bu yöntem subjektiftir ve kişiden kişiye değişebilir. Ayrıca gözlemcinin cinsiyeti, yaşı, kültürel
geçmişi, göz yorgunluğu ve ortama bağlı faktörler ile değişebilir. Ancak görsel
renk seçimi halen diş hekimliğinde en sık kullanılan renk seçim yöntemdir. Daha
estetik ve güvenilir sonuçlar elde edebilmek için aletli renk seçim yöntemleri geliştirilmiştir.
Bu yöntemde spektrofotometre, kolorimetre ve dijital kameralar kullanılır. Bu
cihazlar farklı şartlarda bile tutarlı sonuç verebilir ancak görsel yönteme
kıyasla daha uğraştırıcı ve pahalıdır.

Effect of adjunctive amoxicillin/metronidazole treatment on subgingival Tannerella forsythia, Prevotella intermedia and Fusobacterium nucleatum recolonization in periodontitis patients
Authors: YAPRAK Emre , ARSLAN Uğur , ATAOĞLU Tamer 
Published: July 2019

Background: The use of antibiotics adjunctive to non-surgical
periodontal treatment is an accepted approach in the treatment of
periodontitis. However, bacterial recolonization is a major drawback which complicates
the maintenance of therapeutic acquisitions. The aim of this study was to
evaluate the clinical and microbiological effects of adjunctive amoxicillin and
metronidazole combination in the treatment of periodontitis during 6 months
follow-up.Methods: Twenty-two periodontitis patients were assigned as
test (n=12) and control (n=10) groups. While test group received amoxicillin
and metronidazole combination as an adjunct to scaling and root planing,
control group treated with scaling and root planing alone. Clinical
examinations and subgingival dental plaque sampling were conducted at baseline
and 1, 3 and 6. months during the follow-up. Fusobacterium nucleatum, Tannerella forsythia and Prevotella intermedia levels were
determined using real time polymerase chain reaction method.Results: Both groups exhibited significant improvements in
each follow-up period when compared to baseline. However, clinical improvements
in test group were more prominent than control group as 3rd and 6th
months. While some decrease was notable in the counts of all investigated bacteria
in both groups, only T. forsythia
levels significantly reduced at all follow-up months in test group comparing
with controls.Conclusions: The results of this study indicated that
amoxicillin/metronidazole treatment adjunctive to scaling and root planing
provided additional clinical benefits and suppressed the T. forsythia recolonization.Keywords: periodontitis; amoxicillin; metronidazole; Real-Time

Photocatalytic activity under visible light irradiation of cement based materials containing TiO2-xNy nanoparticles
Authors: Dorkis Ludovic I. , Cohen Juan David , Tobón Jorge I. 
Published: July 2019

Self-cleaning activity of Portland cement pastes blended with nanoparticles of titanium oxynitride (TiO2−xNy) was studied. Samples with various amounts of TiO2−xNy (1% and 3%) were evaluated under irradiation of UV and visible light, and with two curing ages (65 hour and 28 days). Rhodamine B was the pigment used and its loss of color on the cement pastes was carried out using a Spectrometer UV/Vis measuring the coordinates CIE (Commission Internationale de l’Eclairage) L∗, a∗, b∗. Discoloration of Rhodamine B on the surface of the samples was established as the photocatalytic efficiency coefficient (ε). In addition, samples with TiO2 nanoparticles (1% and 3%) were studied under the same conditions and their performances were compared with TiO2-xNy. The presence of nitrogen in the tetragonal structure of TiO2 was evidenced by X-ray diffraction (XRD), ultraviolet-visible diffuse reflectance spectrophotometry and Carbon, Hydrogen and Nitrogen (CHN) analysis. The band gap for TiO2 and TiO2-xNy was determined by the transformed Kubelka-Munk function ( [F (R∞) hv]1/2). The results have shown a similar behavior for both additions under UV light irradiation, with 3% being the addition with the highest photocatalytic efficiency obtained in the early ages of curing time. TiO2−xNy showed activity under irradiation with visible light, unlike TiO2, which could only be activated under UV light. At the late curing ages, the samples with 3% of TiO2-xNy showed the highest efficiency under irradiation of UV and visible light.
From Bits to Bodies: Perfect Humans, Bioinformatic Visualizations, and Critical Relationality
Authors: Hamilton Jennifer A 
Published: July 2019

In December 2014, computational biologist Lior Pachter posted the results of his “tongue in cheek” in silico genome experiment on his personal blog, where he declared his discovery that “the perfect human is Puerto Rican.” In this article, I analyze the “perfect human” experiment. I argue that despite the use of 21st-century, cutting-edge technology in computing and genomics, Pachter’s experiment and his use of visualization can be usefully juxtaposed with earlier modes of visualizing heredity, namely the development of composite portraiture in the late-19th century and late-20th century technologies of “morphing.” I temper the celebration of Pachter’s creation of a “mixed race” perfect human in silico with a challenge to its ostensibly progressive stance. I instead suggest that it must be understood in the broader context of eugenic hauntings and contemporary tensions around questions of sex, sexuality, race, nation, and indigeneity. I argue that the scientific, specifically genomic, stories that we tell, can be productively read in light of critiques of biogenetic kinship and the naturalization of heterosexual love. I conclude by arguing that the perfect human experiment makes a particular kind of argument about what it means to be human and perfect and what constitutes legitimate and cognizable modes of relationality.
Vocational teachers’ personality, career calling and the aspects of teaching quality
Authors: Kovalcikiene Kristina , Daukilas Sigitas 
Published: July 2019

Nowadays , the decline in the prestige of the vocational teacher profession is a great challenge and requires a thorough exa mination of teachers' personality and its relationship with teaching quality. The aim of the research is to analyse the relationship between vocational teachers' personality traits, career calling and the aspects of tea ching quality. Three hundred and forty-six vocational teachers from Lithuania participated in the research. The results revealed that only slightly more than one-third of vocational teachers' has chosen the tea ching profession as calling. The high level of extra version ( p < 0.01), openness to experience (p < 0.01) and low level of neuroticism (p < 0.01) are related to professional calling of vocational teachers. Also, the various aspects of teaching quality are closely related to teachers' personality traits. Thus, the research findings might serve as the basis for providing a more comprehensi ve view of the ps ychologi cal fa ctors of the vocational teachers' profession.
