Abstract
Selective Laser Melting (SLM) is an additive manufacturing method that is used to fabricate different types of complex components using a layer-by-layer approach. The parts are produced directly from three-dimensional computer-aided design data by melting the powdered material layer-by-layer with the aid of laser power. In this work, an experimental investigation of the process parameters of the SLM method using stainless steel 316L powder was conducted. The influence of laser power, scanning speed, and hatching distance on the surface roughness of the specimens was investigated. The design of experiment was conducted using Taguchi’s L16 orthogonal array. Furthermore, statistical analysis using signal-to-noise (S/N) response and analysis of variance (ANOVA) was used to obtain the optimal parameter combinations of the SLM process. From the experimental results, it was found that laser power has the greatest effect on the surface roughness relative to scanning speed and hatching distance. Moreover, using regression analysis, the predicted values of surface roughness and signal-to-noise ratios were obtained. The predicted values were then compared with the experimental values. Lastly, shot peening technique was used to improve the surface roughness of the manufactured components. The results show that the shot peening process offers about 33.28 % reduction in the surface roughness of the manufactured parts.

Published: March 2018

AbstractIn barley, it is possible to induce embryogenesis in the haploid and uninucleate microspore to obtain a diploid plant that is perfectly homozygous. To change developmental fates in this fashion, microspores need to engage in cellular de-differentiation, interrupting the pollen formation, and restore totipotency prior to engaging in embryogenesis. In this work, we used the barley cultivar Gobernadora to characterize the transcriptome of microspores prior to (day 0) and immediately after (days 2 and 5) the application of a stress pretreatment. A deep RNA-seq analysis revealed that microspores at these three time points exhibit a transcriptome of ∼14k genes, ∼90% of which were shared. An expression analysis identified a total of 3,382 differentially expressed genes (DEGs); of these, 2,155 and 2,281 DEGs were respectively identified when contrasting expression at days 0 and 2 and at days 2 and 5. These define 8 expression profiles in which DEGs share a common up- or down-regulation at these time points. Up-regulation of numerous glutathione S-transferase and heat shock protein genes as well as down-regulation of ribosomal subunit protein genes was observed between days 0 and 2. The transition from microspores to developing embryos (days 2 vs. 5) was marked by the induction of transcription factor genes known to play important roles in early embryogenesis, numerous genes involved in hormone biosynthesis and plant hormonal signal transduction in addition to genes involved in secondary metabolism. This work sheds light on transcriptional changes accompanying an important developmental shift and provides candidate biomarkers for embryogenesis in barley.

The Relationship between Religiosity, Environmental Orientation and Environmental Behaviors: An Empirical Study with Turkish and British Muslim Samples
Authors: Ayten Ali , Hussaın Amjad 
Published: March 2018

This article examines the relationship between environmental orientation, behaviour, and religiosity. It also deals with the relations between environmental orientations, behaviours and socio-demographic variables, such as, gender, country and age. The correlational survey method and the questionnaire technique are used for research. The sample covers 342 people ranging from ages 16 to 74. 26% (N= 90) of the sample are British Muslims and 74 % (N= 252) are Turkish Muslims. “Environmental Orientation Scale”, “Environmental Behaviour Scale”, and “Religiosity Scale” measures are applied. The findings indicate that religiosity has a positive effect on ‘environmental stewardship’ and ‘waste management’ however it has no relation to ‘environmental ominion’ and ‘active environmentalism’. In addition, the findings demonstrate that the age and the environmental dominion factors were more effective on environmental behaviour rather than religiosity. The implications of these results and the suggestions for future research are discussed.
Hepatoprotective effect of simvastatin in mice with DMBA-induced breast cancer: Histopathological, biochemical and antioxidant status evaluation
Authors: Ashrafi Mahboobeh , Karimi Behnaz , Sabahi Maryam , Shomali Tahoora 
Published: March 2018

Introduction: This study evaluates the effects of simvastatin on the liver, in a mouse model of DMBA-induced breast cancer, with regards to histopathological, biochemical and antioxidant features.
Methods: Mice were randomly divided into two groups: A (control group) and B (mammary tumor group); the latter group received DMBA (50 mg/kg) by oral gavage once a week for 4 consecutive weeks. Animals positive for breast cancer tumors were randomly divided into 3 subgroups: 1) no treatment group (D1), 2) mice that received simvastatin (80 mg/kg) per os (P.O.) daily for 4 consecutive weeks (D2), and 3) mice that received tamoxifen (50 mg/kg) P.O. daily for 4 consecutive weeks (D3).
Results: Administration of simvastatin to D2 mice resulted in significantly higher superoxide dismutase (SOD) activity as well as glutathione peroxidase (GPx) activity and total antioxidant capacity (TAC), and accompanied by reduced malondialdehyde (MDA) content in liver as compared to D1 group. Tamoxifen significantly increased liver glutathione (GSH) content as compared to D1 mice. Moreover, MDA levels in liver of mice treated with tamoxifen were significantly lower than in the D1 group. Mice in the D1 group showed significantly increased levels of alkaline phosphatase (ALP), aspartate transaminase (AST), and gamma-glutamyl transferase (GGT) in liver tissues; these levels were significantly reduced by simvastatin administration. Moreover, tamoxifen decreased ALP and AST activities. Histopathological examination of liver sections from mice in the D1 group showed severe deteriorative changes. The extent and severity of changes in D2 and D3 groups were almost the same and milder than D1 group.
Conclusion: In conclusion, simvastatin appears to have a hepatoprotective role in mice with DMBA-induced breast cancer, due partly to its antioxidant properties.
Formation and development of Mykola Kostomarov's historiosophical views
Authors: Svitlenko Serhii Ivanovych 
Published: March 2018

The domestic and foreign factors of formation and formation of the historiosophical views of the young M. I. Kostomarov are considered. It was shown that during the Kharkiv period the formation of the historiosophical vision of M. I. Kostomarov took place, and in Kiev the formation of the main features of his historiosophical concept. It was proved that in the mid–1830s − mid–1840s M. I. Kostomarov was formed and established as a Ukrainian philosopher of romantic, nation-loving, Slavophil and christocentric world outlook. In the creative work of the thinker found a reflection on such historiosophical problems as histogenesis of mankind, including the Slavs, the purpose, motive, content, structure and prospects of Ukrainian history. In the center of the historiosophy M. I. Kostomarov was the Ukrainian people as a motive of historical existence with their peopleʼs idea, character and needs. According to the thinker, the key factor in the progress of history was the issue of faith, which was interwoven with social, political, military and ethnic factors. The purpose of history was the realization of the main popular idea of Ukrainians, which they saw as independence and freedom. M. I. Kostomarov formulated the idea of national-cultural revival of Ukraine and the creation of a democratic and republican society within the federation of Slavic peoples, which was an alternative to the imperial regimes. Contradictions in the thinkerʼs outlook are associated with the presence of double loyalty and identity.
The Philanthropic Organizations' Assistance to Jews of Romania and "Transnistria" during the World War II
Authors: Radchenko Iryna Gennadiivna 
Published: March 2018

The article is devoted to assistance, rescue to the Jewish people in Romanian territory, including "Transnistria" in 1939–1945. Using the archival document from different institutions (USHMM, Franklyn D. Roosevelt Library) and newest literature, the author shows the scale of the assistance, its mechanism and kinds. It was determined some of existed charitable organizations and analyzed its mechanism of cooperation between each other. Before the war, the Romanian Jewish Community was the one of largest in Europe (after USSR and Poland) and felt all tragedy of Holocaust. Romania was the one of the Axis states; the anti-Semitic policy has become a feature of Marshal Antonescu policy. It consisted of deportations from some regions of Romania to newly-created region "Transnistria", mass exterminations, death due to some infectious disease, hunger, etc. At the same moment, Romania became an example of cooperation of the international organizations, foreign governments on providing aid. The scale of this assistance was significant: thanks to it, many of Romanian Jews (primarily, children) could survive the Holocaust: some of them were come back to Romanian regions, others decide to emigrate to Palestine. The emphasis is placed on the personalities, who played important (if not decisive) role: W. Filderman, S. Mayer, Ch. Colb, J. Schwarzenberg, R. Mac Clelland and many others. It was found that the main part of assistance to Romanian Jews was began to give from the end of 1943, when the West States, World Jewish community obtained numerous proofs of Nazi crimes against the Jews (and, particularly, Romanian Jews). It is worth noting that the assistance was provided, mostly, for Romanian Jews, deported from Regat; some local (Ukrainian) Jews also had the possibility to receive a lot of needful things. But before the winter 1942, most of Ukrainian Jews was exterminated in ghettos and concentration camps. The main kinds of the assistance were financial (donations, which was given by JDC through the ICRC and Romanian Jewish Community), food parcels, clothes, medicaments, and emigrations from "Transnistria" to Romania, Palestine (after 1943). Considering the status of Romania (as Nazi Germany's ally in World War II), the international financial transactions dealt with some difficulties, which delayed the relief, but it was changed after the Romania's joining to Allies. The further research on the topic raises new problem for scholars. Particularly, it deals with using of memoirs. There is one other important point is inclusion of national (Ukrainian) historiography on the topic, concerning the rescue of Romanian Jews, to European and world history context.

Authors: Luchka Liudmyla Mykolaivna 
Published: March 2018

The works by archimandrites Havriil (V. F. Rozanov) and Feodosiy (O. G. Makarevsky), historians A. O. Skalkovsky, D. I. Yavornitsky and V. O. Bidnov were the first documents on the history of the monastery (Novomoskovsk, Dnipropetrovsk Region). The monastery suffered from raids, fires, epidemics and robberies. The monastic archives were largely lost in the military operations. A lot of original documents didnʼt survive. The epidemic of 1750 did a great damage. The paper archive, infected things and monastery items were burned. The archive consisted of clerical documents, volumes of ancient laws, manuscripts and correspondence. The archive contained some other documents of great importance. They are so-called Universals, 11 statements with seals of Zaporizhian Sich Kosh (Leader) and priorsʼ complaints. The monastery archive contained manuscripts by the last Kosh Otaman (leader) − P. Kalnyshevsky. The archive included documents of state and local authorities and supreme church governing boards – reports, orders, decrees, warrants referring to the monastery property, inventories of monastery household items. A certain percentage of documents was correspondence among priors referring to internal discipline and economic life of the monastery. The names of famous visitors of the monastery are known: archimandrites Havriil and Feodosiy, A. O. Skalkovsky, A. P. Chirkov, P. M. Sochinskiy, V. D. Mashukov, D. I. Yavornitsky and V. O. Bidnov. They worked with documents and left published articles, essays and reviews. Except manuscripts the monastery had printed editions. The monastery library kept 150 liturgical books of Kyiv and Moscow publishing of the 17th − 18th centuries. Six printed books from Samara Desert-Nicholas Monastery are kept in Dnipropetrovsk National Historical Museum. The library collection of the 19th century was quite big. The research of the archive and the library of the monastery give an opportunity to highlight some of the unknown facts on library science and find rare editions of Ukrainian culture heritage.
Agrarian policy of the Ukrainian State on the journals of the meetings of the Council of Ministers
Authors: Arkhireyskyi Dmytro Volodymyrovych 
Published: March 2018

The information content of the journals (minutes) of the meetings of the Council of Ministers of the Ukrainian State (1918) is investigated, which makes it possible to clarify the specifics of governmental agrarian policy. Information on the influence of the German and Austro-Hungarian military command on the agrarian policy of Ukraine, the peculiarities of land ownership and agrarian relations, the food and price policy of the Ukrainian government, and attempts at agrarian and land reform are discussed. The journals of the meetings of the Council of Ministers contain information about the emergence of a peasant rebel movement, caused in general by the unsuccessful agrarian activity of Hetman P. Skoropadsky, and also about government measures aimed at suppressing this movement. The investigated documentary complex should be recognized as an important source on the history of not only the Ukrainian State, its agrarian policy, but also the insurrectional movement and the Ukrainian Revolution of 1917−1921 generally.
Transexualidad y transfobia en el sistema educativo
Authors: Carvajal Villaplana Álvaro 
Published: March 2018

El artículo analiza cómo se presenta la transexualidad en las personas adolescentes, para lo cual se recurre a argumentos científicos, en especial de la biología y las neurociencias. Además, se estudian algunos aspectos de cómo se conforma la identidad transexual en la adolescencia. Por otra parte, se escruta cómo la diferencia sexual establecida por la transexualidad produce actos de discriminación y violencia en el sistema escolar. Se intentará determinar algunas formas en que el sistema educativo funciona, por lo general, como un sistema transfóbico, el que expulsa a los(as) adolescentes transexuales. Por último, se resumen algunos mecanismos y acciones que pueden conformar protocolos de intervención para proteger y favorecer los derechos humanos de estas personas. Se revisan varios estudios sobre el caso de Costa Rica entre los años del 2008 al 2016, y se señala que en el país no existen investigaciones sociales sobre este importante tema.

Published: March 2018

Partiendo de los problemas que genera la cultura light en la población adulta actual, y considerando que la madurez de los profesionales de la educación es un requisito importante del proceso educativo, en el presente ensayo se propone el empleo del método trascendental de Bernard Lonergan como estrategia para la conscienciación del profesorado a través de la construcción social del conocimiento de la realidad y de los problemas circundantes, empleando el diálogo multidisciplinario. Se espera que la profundización hacia niveles mayores de conocimiento, además de promover la conscienciación de los docentes, también promueva el diálogo, la empatía, el trabajo colaborativo y el compromiso con sus estudiantes, su institución y su comunidad.
Suriyeli Mültecilerin Türkiye'deki Algıları
Authors: Özdemir Erol

2010 yılında başlayan Arap Baharı, Ortadoğu bölgesinde birçok ülkeyi
doğrudan veya dolaylı etkilemiştir. Bölgede meydana
gelen rejim karşıtı gösteriler Mart 2011 tarihinde Suriye’de de başlamıştır. Bu
tarih itibariyle göstericilere karşı Suriye rejiminin sert tutumu ve akabinde başlayan iç savaş,
sivil halkın göç etmesine yol açmıştır. Suriye’deki iç savaşın şiddetine bağlı
olarak milyonlarca Suriyeli Türkiye’ye göç etmiştir. Nisan 2011 tarihinden
itibaren Suriyeli mültecileri misafir eden Türkiye, Arap Baharı’ndan dolaylı
biçimde etkilenmiştir. Türkiye “açık kapı” politikası çerçevesinde din, dil ve ırk ayrımı yapmadan
sınırdan giriş yapan hiçbir Suriyeliyi geri göndermemiş ve kendilerine “geçici
koruma statüsü” vermiştir. Bunun yanı sıra sınırdan giriş yapan mültecilerin
kayıtları yapılmakta daha sonra kamplara yerleştirilmektedir. Ancak kampların
kapasiteleri yetersiz kaldığından kamp dışında bulunan mültecilerin zor
koşullarda hayatlarını sürdürmeleri, dilencilik yapmaları ve suça bulaşmaya
eğilimli olduklarına dair toplumda oluşan ön yargı endişelere yol açmaktadır.
Suriyeli mültecilerin farklı dil, kültür ve yaşam tarzına sahip olmaları Türk
toplumu ile Suriyelilerin kaynaşmasını engellediği gibi toplumda karşılıklı
olumsuz algıların oluşmasına yol açmaktadır. Bundan dolayı Suriyeli mültecilere
yönelik toplumun dilinde olumsuz kanaatlerin dolaşımını
sağlayan duyumlar ve damgalayıcı stereotipler kullanılmaktadır. Söylemsel
dışlanma ise Suriyeli kimliği üzerinden kültürel dışlanma şeklinde vücut
bulmaktadır.&nbsp; Buna karşın iktidar partililerin siyasi
söylemleri din ve medeniyet eksenli olup Suriyeli mültecilerin algısını
olumlamaktadır. Türkiye’deki siyasi söylemlerin olumlu algı oluşturacak yönde
olması toplumda Suriyeli mültecilere karşı nefret içerikli söylemlerin önüne
geçtiği gibi ayrımcılık, ırkçılık gibi ötekileştirmenin önüne de geçmektedir.
Iron Interstitial Defects Stability: Under the Uniaxial Stress Effect
Authors: Banısalman Mosab Jaser , Oda Takuji 
Published: March 2018

Understanding of defect kinetics under stress fields is important for multiscale modeling
of nuclear materials degradation. By means of molecular dynamics (MD)
simulation, the formation and migration energies were evaluated for
self-interstitial atom (SIA) and SIA clusters (1~3 interstitials) in alpha Fe.
Effects of 0~3% uniaxial tensile [100] strains were tested for SIAs of
&lt;110&gt; and &lt;111&gt; dumbbell configurations. Regarding the
stability, the &lt;111&gt; dumbbell configurations becomes more stabilized at larger strains and
larger clusters. For
the mobility, the diffusion of single
SIA defects under tensile stresses were traced. Under the free-strain
condition, the diffusivity of the SIA clusters has a gradual transition from
three dimensional (3D) to one dimensional (1D) at saturated strain. The 1D
transition was observed for large clusters and large strain while the 3D
transition was for small clusters and lower strains and presented mainly for
the &lt;110&gt; SIA alignment configuration. Under the tensile stress and for
small clusters, diffusivity enhancement is bigger at a higher temperature.
However, the temperature effect was small for larger clusters. These effects of
strain fields can be explained by elastic interaction between defects and
applied stress fields.

Published: March 2018

Background and Aims: To evaluate the safety and efficacy of transhepatic portal vein embolization with Embosphere, Gelfoam, and Amplatzer vascular plug II before extended hepatectomy in patients with metastatic liver disease. Materials and Methods: Between January 2008 and October 2014, patients with metastatic liver disease, who were treated with transhepatic endovascular portal vein embolization before extended hepatectomy to increase the future remnant liver volume, were retrospectively evaluated. Multidetector computed tomography was utilized before and after the hepatectomy to calculate the future remnant liver volume. Ipsilateral portal vein embolization was performed in all patients with a microspheric embolic agent (Embosphere, 700–900 µm), gelatin foam (Gelfoam), and Amplatzer vascular plug II. Primary outcome measures are the increase in the percentage of the future remnant liver volume, procedure-related mortality and morbidity, and both technical and clinical success rates. Results: Fourteen (78%) right portal vein and 4 (22%) left portal vein embolizations were performed in a total of 18 patients (12 men and 6 women) with a mean age of 48±10.1 years (range, 32 to 59 years). The mean increase in the future remnant liver volume at 6 weeks was 41.6±6.7% (range, 35% to 45%), which was sufficient for extended hepatectomy, and the clinical success rate was 100%. The technical success rate was 100%, and there was no procedure-related mortality. A self-limited subcapsular hematoma occurred in one patient (5%). There was no recanalization of embolized portal veins during follow-ups. Conclusion: Transhepatic portal vein embolization with Embosphere, Gelfoam, and Amplatzer vascular plug II before extended hepatectomy in patients with metastatic liver disease, is a safe and effective procedure.
