Authors: Aldahmash Abdulwali H. , Alshmrani Saeed M. , Almufti Abdo N. 
Published: June 2017

Abstract
The importance of reflection in teaching and learning lies in encouraging one to view problems from different perspectives. Reflective practice can be useful in designing teacher education and sustainable professional development. Conscious reflection is an important element for helping teachers and learners in problem-solving and decision-making processes and fostering their critical-thinking abilities. The aim of the present research was to investigate teachers’ views about the nature of their experiences with reflective practices and reflective teaching. A survey consisted of three dimensions used to collect the data. It was distributed to 458 (237 male and 221 female) science teachers working at high schools in Saudi Arabia. The results have indicated that teacher practices of almost all reflective activities included in the three dimensions “the extent of practicing reflection”, “areas of practicing reflection”, and “ways of practicing reflection” are at “high” level from their point of view. The results have also shown that there are no significant differences in the teachers’ views about their practices of reflective activities related to their gender, or experiences in the teaching profession.
Bullying and Victimisation Dynamics in High School: An Exploratory Case Study
Authors: George Lucy M. , Strom B. Ivan 
Published: June 2017

AbstractBullying is a worldwide concern and erroneous perceptions of the phenomenon could underscore unsustainable interventions. The purpose of this qualitative exploratory case study was to examine, in-depth, how some high school teachers from two schools in New Jersey perceived student bullying. The primary research question was: What perceptions do teachers have about student bullying? The main data were from face-to-face interviews with 14 teachers who answered semi-structured, open-ended questions. Secondary data originated from physical artefacts. The data analysis consisted of four phases. Inductive analysis allowed for the composition of individual cases. Cross-case analysis allowed data classification into three main areas of inquiry aligned with the three secondary research questions (a) bullying and victimisation dynamics as perceived by teachers, (b) adequacy of current interventions, and (c) adequacy of teachers’ professional development for bullying mitigation. The data unveiled inconsistencies between causes of bullying and interventions. It culminated in recommendations for leadership and suggestions for future research.

Authors: Ozmen Hilal Kiziltunc , Erdemci Burak , Askin Seda , Sezen Orhan 
Published: June 2017

Abstract
In this study, serum carnitine (CRNT) and adiponectin (APN) levels and the correlation of these parameters in patients with breast cancer before and after treatment with radiotherapy (RT) were determined.

Materials and methods
Serum adiponectin and carnitine levels were assessed in 58 patients with breast carcinoma and 30 control subjects. Serum carnitine and APN levels were determined using a specific enzyme-linked immunosorbent assay.

Results
While serum carnitine level was significantly lower in the patients with breast cancer after RT compared with the control group and before treatment (p=0.002 and p=0.019, respectively), serum APN level was significantly higher than in the control group and before treatment ( p=0.003 and p=0.027, respectively). Carnitine level showed a negative correlation with APN level in the patients after RT (r= -0.626, p= 0.001). There was no correlation between carnitine and APN levels in subjects of control group and before treatment. Also, neither carnitine nor APN levels demonstrated correlation other parameters.

Conclusions
Results suggest that increased serum adiponectin and decreased carnitine levels in breast cancer after RT than control group. Carnitine level showed a negative correlation with APN level in the patient with breast cancer after RT. While carnitine, HDL-C and total cholesterol levels are decreased, trygliceride and LDL-C levels are increased in patients than control group. In addition, serum APN concentration was inversely correlated with serum carnitine levels. Furthermore, increased serum APN level in breast cancer after RT might be associated with hypocarnitinemia.
Numerical simulation on ferrofluid flow in fractured porous media based on discrete-fracture model

Abstract
Water flooding is an efficient approach to maintain reservoir pressure and has been widely used to enhance oil recovery. However, preferential water pathways such as fractures can significantly decrease the sweep efficiency. Therefore, the utilization ratio of injected water is seriously affected. How to develop new flooding technology to further improve the oil recovery in this situation is a pressing problem. For the past few years, controllable ferrofluid has caused the extensive concern in oil industry as a new functional material. In the presence of a gradient in the magnetic field strength, a magnetic body force is produced on the ferrofluid so that the attractive magnetic forces allow the ferrofluid to be manipulated to flow in any desired direction through the control of the external magnetic field. In view of these properties, the potential application of using the ferrofluid as a new kind of displacing fluid for flooding in fractured porous media is been studied in this paper for the first time. Considering the physical process of the mobilization of ferrofluid through porous media by arrangement of strong external magnetic fields, the magnetic body force was introduced into the Darcy equation and deals with fractures based on the discrete-fracture model. The fully implicit finite volume method is used to solve mathematical model and the validity and accuracy of numerical simulation, which is demonstrated through an experiment with ferrofluid flowing in a single fractured oil-saturated sand in a 2-D horizontal cell.
At last, the water flooding and ferrofluid flooding in a complex fractured porous media have been studied. The results showed that the ferrofluid can be manipulated to flow in desired direction through control of the external magnetic field, so that using ferrofluid for flooding can raise the scope of the whole displacement. As a consequence, the oil recovery has been greatly improved in comparison to water flooding. Thus, the ferrofluid flooding is a large potential method for enhanced oil recovery in the future.

Published: June 2017

AbstractThe kynurenine pathway (KP) is the metabolic pathway via which L-tryptophan is converted to nicotinamide. It serves important immune-regulatory roles. This article will review the evidence for involvement of the KP in scleroderma and present a possible model of kynurenine regulation of the cytokine cascade.
Long term results of radiotherapy in vulvar cancer patients in Slovenia between 1997–2004
Authors: Zobec Logar Helena Barbara 
Published: June 2017

Abstract

Background
The aim of this retrospective single institution study was to analyse long term results of vulvar cancer treatment with conventional 2D radiotherapy in Slovenia between years 1997–2004.

Patients and methods
Fifty-six patients, median age 74.4 years +/- 9.7 years, mainly stage T2 or T3, were included in the study. All patients were treated with radiotherapy, which was combined with surgery (group A), used as the primary treatment (group B) or at the time of relapse (group C). Chemotherapy was added in some patients. Histology, grade, lymph node status, details of surgery, radiation dose to the primary tumour, inguinofemoral and pelvic area as well as local control (LC) and survival were evaluated.

Results
Overall survival (OS), disease specific survival (DSS) and LC rates at 10-years for all patients were as follows: 22.7%, 34.5% and 41.1%, respectively. The best 10-years results of the treatment were achieved in the primary operated patients treated with adjuvant radiotherapy +/-chemotherapy (OS 31.9%, DSS 40.6% and LC 47.6%). Positive lymph nodes had a strong influence on LC. In case of positive nodes LC decreased by 60% (p = 0.03) and survival decreased by 50% (p = 0.2). There was a trend to a better LC with higher doses ≥ 54.0 Gy (p = 0.05).

Conclusions
The best treatment option for patients with advanced vulvar cancer is combined treatment with surgery and radiotherapy +/- chemotherapy, if feasible. Radiotherapy with the dose of ≥ 54.0 Gy should be considered to achieve better LC if positive adverse factors are present.
Language Learners or New Speakers: The Transfer of the Breton Diwan Immersion Education Model to the Lower Sorbian Witaj Project
Authors: Dołowy-Rybińska Nicole 
Published: June 2017

AbstractThe paper discusses several aspects of immersion and bilingual education systems in Brittany, France and in Lower Lusatia, Germany. Their role in the process of becoming a new speaker of a minority language is exemplified by the Diwan immersion education model in Brittany and the Witaj project in Lower Lusatia concerning the Sorbian people. Taking into consideration the different sociolinguistic situation of both groups, the level and reasons for language shift, the existing language policy in France and in Germany, both educational models are presented. I analyze some factors that influence the possible success or failure of these two models, such as: the linguistic environments, teaching systems, the roles of teachers, the minority language attitudes of pupils, their language practices, the availability of extracurricular activities in the minority language, and the existence of different types of communities of practice. All these factors influence pupils’ language choices and practices. Not all language learners will use a minority language in the future, since it depends on the conscious decision of each person. The distinction between language learners and minority language new speakers can thus be justified.
Standardization of blood tube closure colors may be important in reducing tube selection errors of non-laboratory personnel
Authors: Aydin Ozlem 
Published: June 2017

Abstract
Errors in laboratory medicine contribute significantly to the overall risk of errors in healthcare. The majority of these laboratory errors occur in the pre-analytical phase. Control of pre-analytical variables is difficult because many steps are outside the control of the laboratory management. Pre-analytical errors may be reduced by active monitoring and control of all possible errors that are caused by non-laboratory personnel drawing blood, continuous training, use of quality indicators and implementation of standard procedures. Non-laboratory personnel make blood collection tube selection mostly according to the closure color, so standardization of color coding for blood tube closures could help reduce sample collection errors. It is important that European Federation of Clinical Chemistry and Laboratory Medicine calls all stakeholders in the healthcare sector to harmonize color coding for blood collection tube closures. Non-laboratory personnel drawing blood can be taught the additives in blood tubes and their functions to reduce errors during the sample collection stage. In addition, standardization of the closure colors of blood tubes should be supported, and non-laboratory personnel drawing blood should be informed when there is a change in the tube closure colors used by the hospital until this standardization is achieved.
The Priestly Grundschrift: Source or Redaction? The Case of Exodus 12:12–13
Authors: Tucker Paavo N. 
Published: June 2017

Zusammenfassung:Aktuelle Studien zur priesterschriftlichen Erzählung im Pentateuch zeigen, dass die Forschung hinsichtlich des Charakters der priesterschriftlichen Erzählung als Quelle oder Redaktion einen Stillstand erreicht hat. Der Artikel untersucht, wie Ex 12,12–13 zum Verständnis des Charakters der priesterschriftlichen Erzählung beiträgt. Im Anschluss an die Vorgehensweise David Carrs kann gezeigt werden, dass der priesterschriftliche Passah-Bericht in Ex 12,12–13 die Traditionen der nicht-priesterschriftlichen Passahgeschichte aus Ex 12,21–23 mit der Tötung der Erstgeburt aus Ex 12,29–33 verschmilzt und diese im Licht der priesterschriftlichen Theologie umformuliert und sie in die priesterschriftliche Erzählung integriert. Diese Kompositionsmethode legt nahe, dass die Vorlage mit den Schlüsselverben der rituellen Anweisungen aus Ex 12,21–23 korrespondiert, statt zu postulieren, dass der priesterschriftliche Bericht der Verse 1–13 eine frühere Vorlage in den Versen 3b.6b.7a.8a.11bβ integriert hat. Der priesterschriftliche Bericht verwendet die Anweisungen aus den Versen 21–23 für die Formulierung von Anweisungen für seine eigene Wiedergabe des Passah in den Versen 1–11. Die Verschmelzung von Ex 12,21–23 und 29–33 in Ex 12,12–13, wie auch die Verwendung der Anweisungen aus den Versen 21–23 in den Ritualen der Verse 1–11 legen nahe, dass die priesterschriftliche Erzählung in Ex 12,1–13 ein redaktioneller Zusatz zu den vorpriesterschriftlichen Traditionen ist.
Acciones y omisiones obligatorias y meritorias. Una perspectiva utilitarista
Authors: Rodríguez López Blanca 
Published: June 2017

Una de las críticas más habituales contra el utilitarismo consiste en señalar su incapacidad para reconocer la relevancia moral de la distinción entre acciones y omisiones. Según esta crítica, afirmar la irrelevancia de esta distinción 1) va en contra de las intuiciones del sentido común, 2) elimina la diferencia entre lo obligatorio y lo meritorio y 3) hace inviable la propuesta utilitarista, al proponer una moral demasiado exigente. En este trabajo nos centraremos en el segundo aspecto de esta crítica, y defenderemos que el utilitarismo sí dispone de los medios para distinguir entre lo obligatorio y lo meritorio. Asimismo, defenderemos que l utilitarismo no necesita renunciar a afirmar la irrelevancia moral de la distinción entre acciones y omisiones para responder adecuadamente a esas críticas. Para ello, nos valdremos fundamentalmente del análisis ofrecido por John S. Mill en el capítulo cinco de su obra Utilitarismo, en el que a nuestro juicio puede encontrase la versión clásica de la respuesta a esta crítica, que de una u otra manera los utilitaristas contemporáneos han asumido y desarrollado.
Investigation of Seizure-Susceptibility in a Drosophila melanogaster Model of Human Epilepsy with Optogenetic Stimulation
Authors: Saras Arunesh , Wu Veronica V , Brawer Harlan J , Tanouye Mark A 
Published: June 2017

Abstract
We examined seizure-susceptibility in a Drosophila model of human epilepsy using optogenetic stimulation of ReaChR (red-activatable channelrhodopsin). Photostimulation of the seizure-sensitive mutant parabss1 causes behavioral paralysis that resembles paralysis caused by mechanical stimulation, in many aspects. Electrophysiology shows that photostimulation evokes abnormal seizure-like neuronal firing in parabss1 followed by a quiescent period resembling synaptic failure and apparently responsible for paralysis. The pattern of neuronal activity concludes with seizure-like activity just prior to recovery. We tentatively identify the mushroom body as one apparent locus of optogenetic seizure initiation. The α/β lobes may be primarily responsible for mushroom body seizure induction.
Kovárványcsíkok képződése a Nyírség homoktalajában

Published: June 2017

A Nyírség egyik jellegzetes talajtípusa a kovárványos barna erdőtalaj. Mind hazánkban, mind külföldön sokan vizsgálták a kovárványképződést és állítottak fel természettudományosan megalapozott elméleteket a képződés mikéntjére vonatkozóan. Leggyakrabban a vas-vegyületek lefelé irányuló mozgásávbal és adott mélységben történő kicsapódásával próbálták meg leírni a jelenséget. Munkánk célja ásványtani, talajtani és mikrobiológiai vizsgálatok segítségével megválaszolni a kovárványképződésének kérdését.
A Nyírség tamáspusztai homokdomb alapvetően homogénnek tekinthet ásványi összetételét tekintve. A kovárványszintek képződésének korábban leírt kémiai és szemcseösszetételbeli kritériumai teljesülnek (pH 4.5–6.5 közé esik, a szemcseösszetétel pedig a kovárványrétegben meghaladja a leiszapolható rész 10 %-ot). Részletesen vizsgálva a kovárványrétegeket benne a homokszemcsék korrodáltak, töredezettebbek, ami mind egykori gyökérnedvek korróziójának eredménye lehet. A homokszemcsék kötőanyaga a kovárványrétegben elsősorban vas-oxihidroxidból áll, és a kovárványréteg eredetileg képlékeny, gyúrt, szakadozott szerkezetet mutat. A kovárványréteg felső része erodált, ami egykori talajfelszínen történő elhelyezkedését jelzi. A réteg alsó része tagolt és gyakran benyúlik az alatta elhelyezkedő homoktestbe. Véleményünk szerint a vas-oxihidroxid kiválások a kovárványrétegben alapvetően biológiai (növényi vas felvétel, majd elhalás után mikrobiális bontás segítségével létrejött vas-oxihidroxid akkumuláció) akkumulációs és kiválási folyamatokra utalnak. Mindezek alapján úgy gondoljuk, hogy a kovárványrétegek az egykori homokdomb felszínén képződtek és nem később bekövetkezett vasmozgás során jöttek létre.

Published: June 2017

Due to growth of mechanization and automation, today’s industrial systems are becoming more complex. A small breakdown of any non-redundant machine component affects the operation of the entire system. Compressors are utilized widely in the oil and chemical industry. Great attention has been paid to the condition monitoring and fault diagnosis of the Compressor by the field engineers and technicians. In this study, an effective and reliable method based on vibration analysis and with signal processing and classification techniques is presented for troubleshooting of a centrifugal Compressor. Among different time – frequency methods, wavelet transformation extracts information about the signal time scale through a series of convolution operation between the measured signals and the basis wavelet which was used as a preprocessing. The used mother wavelet is (db4) in which the original signal is switched to multiple details signals; then it features are taken from pre-processed signals and they were introduced to support vector machines as input. Kernel function used here in the support vector machine is RBF in which the parameters of support vector machine were optimized using Genetic Algorithm for better performance to increase the accuracy of classification. The highest accuracy was obtained as 100 %. The obtained accuracy clearly indicates high safety margin of the multistage centrifugal pump for fault detection.
The impact of changed river discharge on water quality deterioration in a prairie lake revealed by the sedimentary evidence
Authors: Gao Hongbin , Li Changyou , Sun Biao 
Published: June 2017

Abstract
In order to investigate the historical water quality state and identify the factors causing modern environmental degradation in a prairie lake, total organic carbon (TOC), total nitrogen (TN), stable carbon isotopes of organic matter and total phosphorus (TP) from lake sedimentary core with high resolution age frame were analyzed. The results show that the values of proxies (TOC, TN, TP, δ13C, C/N) increased significantly after 2000 compared with before, which indicates Lake Hulun has heightened nutrient level and pollution extent, thus induced growth of algal bloom and water quality deteriorated after 2000. Since the event of decreased river discharge and lowered water level began in 2000 corresponds extremely well with our sedimentary records that nutrients pollution and eutrophication occurred in Lake Hulun at the same moment, the change of river discharge can be seen as the primary and direct reason of lake water quality deterioration in this period. In addition, the increased wind and water erosion as a result of serious and widespread destruction of grassland in Lake Hulun basin is the potential factors for changing the nutrients concentration in Lake Hulun.
