Applying design in public administration: a literature review to explore the state of the art
Authors: Hermus Margot , van Buuren Arwin , Bekkers Victor
Published: July 2019

The attention for applying design-oriented approaches in public administration has increased significantly. Applying design is seen as a promising way to deal with wicked problems and create more responsive policies and services. We aim to contribute to the debate on the value of design for public administration and the development of the latter into a design science by conducting a systematic literature review into the empirical applications of design. We analyse the goals, processes and outcomes of 92 empirical studies. Based upon this we distil six design approaches, varying from traditional scientific and informational approaches to innovative, user-driven and thus more ‘inspirational’ approaches. The more traditional (science-driven) approaches still dominate the field. The impact of these types of studies is correspondingly low. We argue that further developing and refining the whole range of design approaches can foster both the scientific rigour and the societal relevance of a design-oriented public administration.

Pengembangan Model Pembelajaran Bahasa Arab Berbasis Teori Multiple Intelligence
Authors: Ahmad Zainal Arifin
Published: July 2019

The discovery of the theory of Multiple Intelligence by Howard Gagner has changed the paradigm of education and learning. If the old paradigm view that intelligence is a single learner who is only measured by IQ tests, then the paradigm of Multiple Intelligence view that intelligence is plural learners. Each individual has the advantage of certain intelligence that may be different with advantages that others have.  That fact has implications for the importance of changing patterns of education and learning, including learning Arabic, from the pattern that is only oriented to the development of intellectual intelligence (IQ) to the pattern of intelligence that takes into account the diversity of learners. This paper describes showing the development of Arabic language instruction model based on the theory of Multiple Intelligence. The model in question is a model of the development of Arabic language learning component which includes the development of Arabic language learning goals, teachers’ roles, attitudes and treatment of students, and the development of materials, methods, media, and evaluating the results of learning Arabic, all of which were based on intelligence insight plural (Multiple Intelligence).

The historical development of the Arabic language in Indonesia can not be separated from the spread of Islam which is the most dominant followed by Indonesian society itself. This has an impact on the development of Arabic learning today, that look is still far from the expected. It seems that view of the cultural and religious patterns of Indonesia in the early 19th century that are still at the level of mythic and theological, less positive effect on the future of Arabic learning in today’s contemporary world. How is the relationship between religion and its influence on the development of the Arabic language, especially in Indonesia will be described in this paper? By using the theory of van Peursen culture and Comte as theoretical analysis, the author tries to find a possible alternative solution of some negative effects in the mythic dimensions of such view, by emphasizing the positive aspects.

Metode Pembelajaran Al-Ashwat
Authors: Mufidah Nuril
Published: July 2019

In Arabic learning, al-Ashwat plays an essential role because al-Ashwat or phonetic is a crucial element in every language. If al-Ashwat is not well understood, Arabic proficiency cannot be mastered perfectly. Often there will be a lack of understanding in the language process. So that the communication process will also be hampered. Learning methods are a way or means to present subject matter. With learning, the approach can simplify and accelerate the learning process towards understanding. There are at least two learning methods that pay attention to the teaching of sound language, including Phonetic Method and Mim-mem Method which is better known as an Audio-Lingual Method.

Published: July 2019

A solid catalyst tailored to perovskite structure was synthesized and investigated for catalytic activity in a transesterification reaction to form biodiesel. The catalyst has demonstrated high catalytic activity and selectivity for biodiesel under very mild reaction conditions and short reaction times. The catalyst system has shown robust resistance to leaching of the active phase when reused. The performance was attributable to the perovskite structure and the dopant metal used. Hence, this work has shown that the structure and dopant metal of the solid catalyst could be tailored to enhance catalytic activity and durability for renewable fuel synthesis.

Authors: Valencia Ayala Edward , Marcos Carbajal Pool , Coelho Eduardo Barbosa , Sandoval Jose Sandoval , Salazar Granara Alberto
Published: July 2019

Background

TheMDR1gene presents several genetic polymorphisms with pharmacological implications. Therefore, the aim of the present study is to establish the genotype and allele frequencies of 3435C>T polymorphism ofMDR1gene into Peruvian populations (Coastal, Andean and Amazonian ecoregions), even considering the altitude (lowland <2500 m and highland >2500 m).

Methods

The polymorphism was analyzed by TaqMan genotyping assays in a group of 181 healthy unrelated Peruvian individuals. The comparison of genotype and allele frequencies of 3435C>T polymorphism was made with the Pearson test (X2), and, to calculate the genotype distributions, the Hardy-Weinberg equilibrium (HWE) was used.

Results

In all populations evaluated in this study, the genotype frequency distributions met HWE assumptions. The comparison between genotype and allele frequencies showed significant differences (p < 0.05), when the Andean, Coastal and Amazonian populations were compared. Also, significant differences (p < 0.05) were obtained when these populations were compared considering their altitudes. Likewise, in comparison with countries like USA, Finland, Nigeria and Kenya, the results showed significant differences (p < 0.05).

Conclusions

This investigation allowed us to establish the genotype and allele frequencies of 3435C>T polymorphism in different Peruvian populations, considering the geographic localization and even the altitude.
Adsorption of Ciprofloxacin from Aqueous Environment by Using Synthesized Nanoceria
Authors: Rahdar Abbas , Rahdar Somayeh , Ahmadi Shahin , Fu Jie
Published: July 2019

Antibiotics are widely detected emerging contaminants in water environments and possess high potential risks to human health and aquatic life. However, conventional water treatment processes cannot remove them sufficiently. To develop innovative nanoadsorbents for effectively remove antibiotic contaminants from water environment, nanoceria were prepared via in situ precipitation method, and evaluated their adsorption capacity for a model antibiotic, ciprofloxacin (CIP). The properties of the prepared nanoceria were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and vibration sample magnetization (VSM). The effect of various operating parameters such as pH, initial CIP concentration, contact time, and adsorbent dosage on adsorptions of CIP were studied in batch experiments. Maximum adsorption capacity of the nanoceria was 49.38 mg/g at the conditions of pH 5, initial CIP concentration of 200 mg/dm3 and adsorbent dosage of 0.2 g/dm3, when 95.43 % of the CIP was removed. For adsorption kinetics, both pseudo-first-order and pseudo-second-order models can well describe the experimental data, indicating that the adsorption process was controlled by both physical diffusion and chemical interaction. For adsorption isotherms, the Freundlich model could fit the experimental data better than the Langmuir and Temkin models, suggesting a multilayer adsorption process. The thermal dynamics study showed the absorption process was spontaneity, exothermic, and irreversible. Finally it was concluded that the nanoceria can be used effectively for CIP removal.

Published: July 2019

In the course of analysing sewage sludge biochar (BC) as a material containing phosphorus loads, we determined the following: effect of thermal conversion of three different sewage sludge biochars on the content and availability of P in biochars (BC-1, BC-2 BC-3), effect of their application on selected forms of P in soil and on the accumulation of this component in Poa pratensis L. biomass. Regardless of the type of BC, the contents of P-H2O and P-CaCl2 were lower than the contents determined in unconverted sewage sludge. A significant increase in the content of P-CaCl2 compared to the control was noted in the soil of treatments where 1 and 2 % additions of BC-2 and BC-3 were applied. Soil pH (r = 0.826; p ≤ 0.05) and the content of Ca-exchangeable (r = 0.712; p ≤ 0.05) had the strongest effect on the content of P-CaCl2 in soil; however, no significant relationship was found between the amount of P-introduced with BC, the contents of Al-ox., Fe-ox. and the content of P-CaCl2. Significant (p ≤ 0.05) increase in the phosphorus content in plant biomass was noted in all treatments compared to the control. Regardless of the type of biochar applied, the highest amount of P-uptake was determined in treatments where the greatest addition of BC (2 %) was introduced into the soil. A significant relationship between P-uptake and the amount of P-introduced with BC into the soil (r = 0.726; p ≤ 0.05) was demonstrated.
Environmentally Friendly Fuel Usage: Economic Margin of Feasibility
Authors: Kalinichenko Antonina , Havrysh Valerii
Published: July 2019

In the world there are two main problems concerning energy and ecology. Despite the crude oil price fluctuation, it has tended to increase. Moreover fossil fuel burning emits hazard compounds, including greenhouse gas. To solve them alternative fuels for vehicle have to be used. In due to properties, their usage impacts on the engine efficiency. The alternative fuel usage needs additional investment costs on the vehicle engines adaptation and fuel supply infrastructure. So, decisions must be based on mathematical apparatus. Three submodels were used in the suggested mathematical model: energy and economic indicator for fuels; energy and economic indicator for vehicles; criteria for investment projects. As a criterion of investment projects the profitability index has been grounded. The mathematical model and the algorithm for determining the feasibility of the alternative fuel utilization have been developed. The proposed algorithm includes the following stages: calculation of the fuel energy cost; calculation of the criteria for vehicles; determining the maximum value of investments; making decisions. Biofuels and gaseous fuels for some countries have been studied. The economic attractiveness of the alternative transport fuels has been presented. According to mathematical modeling, gaseous fuels are more economically attractive compared with liquid biofuels. Among gaseous fuels, LPG has a higher economic efficiency. The economic margin of alternative fuel application feasibility has been determined.
Synergistic flame-retardant effect between lignin and magnesium hydroxide in poly(ethylene-co-vinyl acetate)
Authors: Laoutid Fouad , Duriez Victor , Brison Loic , Aouadi Sabrina , Vahabi Henri , Dubois Philippe
Published: July 2019

In this study, we evaluated the interest of combining magnesium hydroxide (MDH) and lignin for developing complementary flame retardant actions in poly(ethylene-co-vinyl acetate) (EVA). Lignin was selected owing to its char forming ability thatwas supposed to reinforce the endothermic effect provided by MDH. The effect of lignin chemical modification by ammonium phosphate functions also evaluated as a way for enhancing its charring effect. Fire properties and thermal behavior of EVA composites were characterized using cone calorimeter, Pyrolysis Combustion Flow Calorimeter (PCFC) and thermogravimetric analysis (TGA). The effect of the incorporation of lignin alone on EVAcomposite thermal and fire behavior first evaluated. Results evidenced that the incorporation of lignin, whatever its nature, induced important reduction of composite thermal stability during TGA analysis as well as significant reduction of the time to ignition (TTI) in cone calorimeter test. However, a significant reduction of peak of heat release rate (pHRR), higher than that obtained with MDH was observed. The combination of lignin and MDH was led to further reduction of pHRR. Furthermore, it was concluded that the chemical modification of lignin is not required prior obtaining improved flame-retardant properties.

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

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

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

This 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.
Steinberg-like characters for finite simple groups

Let G be a finite group and, for a prime p, let S be a Sylow p-subgroup of G.
A character χ of G is called

Syl
p

{\mathrm{Syl}_{p}}

-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

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

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.
Zu sich selbst in ein Verhältnis treten
Authors: Jornitz Sieglinde
Published: July 2019

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

Published: July 2019

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

Estimation of wave-current force coefficient on inclined cylinder in random waves
Authors: Teng Bin , Li Yu-Cheng
Published: July 2019

In this Paper, the wave-current forces on three kinds of inclined cylinder are measured, and the force coefficients CD and CM are estimated by a revised cross-spectrum method proposed in this Paper. In this method, the force coefficients are considered as constants over the frequency range and are estimated by the least squares method. From the experimental results, it is found that wave directions have an effect on CD and CM values. Following the analysis of the experimental results, two empirical formulae are presented which are used to transform CD and CM into unified force coefficients C′D and C′M. By comparing C′D and C′M with published results for vertical cylinders, it is found that the unified force coefficients from this Paper are consistent with the results obtained by others.
