Authors: ER Harun , KAYMAKCI Selahattin 
Published: October 2018

Literature can be defined as a
branch of art by which people express their emotions, thoughts, imaginations
and ideals verbally or in written through language. It is one of the many
fields utilized by social studies courses that inherently involve several social
disciplines. Several different type of literary works have been used as
teaching materials in social studies teaching. These primarily involve novels,
stories, memoirs, biographies, travel writings, sagas, epics, articles,
proverbs, songs, idioms, legends, poems, tales and theater plays. The aim of
this study is to determine the extent to which social studies teachers use
literary works in their courses. Phenomenology among qualitative methodologies
was used during the research. The study
group consists of 32 social studies teachers working in Bartın province as of
2015-2016 academic year. Structured interview was used as the data gathering
tool. The data obtained within the frame of the study were analyzed using
content analysis. As a result of the research, the majority of participating
teachers were found to be inclined to use literary works in their courses,
although they find the use of literary works in curricula and course books
qualitatively and quantitatively inadequate.
Against statistical significance testing in corpus linguistics
Authors: Koplenig Alexander 
Published: October 2018

AbstractIn the first volume ofCorpus Linguistics and Linguistic Theory, Gries (2005. Null-hypothesis significance testing of word frequencies: A follow-up on Kilgarriff.Corpus Linguistics and Linguistic Theory1(2). doi:10.1515/cllt.2005.1.2.277.http://www.degruyter.com/view/j/cllt.2005.1.issue-2/cllt.2005.1.2.277/cllt.2005.1.2.277.xml: 285) asked whether corpus linguists should abandon null-hypothesis significance testing. In this paper, I want to revive this discussion by defending the argument that the assumptions that allow inferences about a given population – in this case about the studied languages – based on results observed in a sample – in this case a collection of naturally occurring language data – are not fulfilled. As a consequence, corpus linguists should indeed abandon null-hypothesis significance testing.

Published: October 2018

Abstract
Wastewater treatment processes are subject to numerous disturbances during biological treatment of wastewater. In order to achieve and sustain suitable conditions of the process, basic wastewater parameters should be frequently monitored. While great improvements have been made in the automatization of treatment process, little is known about automatic measuring systems that can detect unusual process conditions in a bioreactor. Tracking these parameters can be difficult and the time required for the determination might vary from several minutes to few days. The objective of this study is to evaluate the use of an electronic nose in-house device (based on a non-selective gas sensor array) for the detection of process disturbances in a lab-scale sequencing batch reactor (SBR) during biological treatment of wastewater with activated sludge. Measurements were performed during a 12-hours working cycle. Continuous analyses of the headspace were performed using a sensor array based on the resistive Metal Oxide Semiconductor type (MOS) gas sensor. Based on the data obtained and the PCA analysis, this study showed that the e-nose technology can be used to predict or retrieve information about potential disruptions during wastewater processes using the e-nose technology.

Published: October 2018

Abstract
The field of microbial biotechnology has revolutionized the utilization of microorganisms to overcome the problems of environmental pollutions. The present study aimed to identify silver-tolerant isolates and screen their ability to synthesize silver nanoparticles for possible use as bioremediation agents. Seventeen bacterial isolates from soil collected from the Smokey Mountain landfill in Manila, Philippines, were found to tolerate 0.01 M AgNO3 in the culture medium. Molecular and phylogenetic analyses using the 16S rRNA gene sequence identified the isolates as Bacillus cereus, Bacillus subtilis, Bacillus flexus, Bacillus thuringiensis, Alcaligenes faecalis, Achromobacter sp. and Ochrobactrum sp. The formation of silver nanoparticles was evident in the change in color of the reaction mixtures, and was detected through UV-VIS spectroscopy with absorbance peaks at 250-300 nm and 400-450 nm. Scanning electron microscopy revealed the aggregation of diverse shapes of silver nanoparticles with sizes ranging from 70 to 200 nm. The best silver nanoparticle-synthesizing isolates were Alcaligenes faecalis and Bacillus cereus. The results denote the promising microbial technology application of the 17 silver-tolerant isolates in combating the adverse effects of metals and other pollutants in the environment.

Abstract
The microbial degradation of vinyl acetate (VA) by Pseudomonas fluorescens PCM 2123 strain was studied in both batch and continuous modes. The purpose of the experiments was to determine the kinetic model of the cell growth and biodegradation rate of vinyl acetate (VA), which was the sole carbon and energy source for tested microorganisms. The experiments, carried out in a batch reactor for several initial concentrations of growth substrate in the liquid phase ranging from 18.6 to 373 gsubstrate·m−3 (gs·m−3) made it possible to choose the kinetic model and to estimate its constants. The Haldane inhibitory model with the values of constants: μm

To set the parameters of maintenance metabolism it was necessary to carry out a series of continuous cultures at different dilution rates (0.05 to 0.072 h−1) and concentrations of VA in the liquid supplied to the chemostat ranging from 30.9 to 123.6 gs·m−3. The obtained data-base enabled to determine the coefficient for maintenance metabolism (me

Optimal Allocation of Resources at Risks Occurring in the Nodes of a Network
Authors: Sgurev V. , Drangajov S. 
Published: October 2018

Abstract
A linear programming model is proposed for interpretation of the problem for allocation of resources between a finite number of consumption stores at which the risks occurring are considered. At that linear constraints are imposed between the resources in the detached points and between the risks occurring at that. Results are obtained related to reducing this problem to a general Linear Programming (LP) program in which optimal solution is sought for minimization of the expenses for allocation of the resources as well as for taking the risks. A numerical realization of the linear model proposed is carried out that confirms the theoretical results received.
Wireless Kinect-NAO Framework Based on Takagi-Sugeno Fuzzy Inference System

Published: October 2018

Abstract
In the context of learning new skills by imitation for children with special educational needs, we propose Wireless Kinect-NAO Framework (WKNF) for robot teleoperation in real time based on Takagi-Sugeno (T-S) Fuzzy Inference System. The new solutions here are related to complex whole-body motion retargeting, standing body stabilization, view invariance and smoothness of robot motions. The raw depth Kinect data are fuzzified and processed by median filter. The joint angles estimation for motion mapping of Human to NAO movements is based on fuzzy logic and featured angles rather than direct angles are calculated by Inverse Kinematics due to differences in the human and robot kinematics. During the joint angles calculation nonlinearities are observed as a result of ambiguity of Kinect 3D joint coordinates in different offsets. NAO kinematic limitations and nonlinearities in workspace are decomposed and linearly approximated by T-S fuzzy rules of zero and first order that have local support in 2D projections. To prevent the robot to fall down, the center of mass is considered in order NAO to stay within a support and safe polygon. The feasibility of the proposed framework has been proven by real experiments.

Abstract
The flexible job shop problems (FJSP) are an important class of scheduling problems and they have a significant practical value. Unfortunately it is not easy to solve job shop problems and in particular FJSPs because they are NP-hard problems. In this paper we propose a method for generating a set of feasible schedules for a given FJSP.

Authors: Krastev A. , Chavdarov I. , Dimitrova M. 
Published: October 2018

Abstract
The paper considers a novel algorithm for performing joint tasks between a humanoid robot NAO and a low-budget (Low-Cost) walking robot Big Foot. The specific construction of Big Foot allows movement by walking, change of direction and overcoming obstacles by using only two engines. The principle of movement of Big Foot is presented and the parameters, which determine the step and velocity of movement, are discussed. NAO robot sets the beginning of task execution and controls reaching the target position by the non-humanoid robot. NAO sonars are employed for this purpose. The non-humanoid robot Big Foot is controlled remotely by a human. The information on the timing of the executed movements and the reaching of the target is collected in several ways by using the sensors of NAO and Big Foot. The obtained results are analysed. Possibilities for application of the proposed algorithm are discussed.
CK1α Collaborates with DOUBLETIME to Regulate PERIOD Function in theDrosophilaCircadian Clock

Published: October 2018

The animal circadian timing system interprets environmental time cues and internal metabolic status to orchestrate circadian rhythms of physiology, allowing animals to perform necessary tasks in a time-of-day-dependent manner. Normal progression of circadian rhythms is dependent on the daily cycling of core transcriptional factors that make up cell-autonomous molecular oscillators. InDrosophila, PERIOD (PER), TIMELESS (TIM), CLOCK (CLK), and CYCLE (CYC) are core clock proteins that function in a transcriptional–translational feedback mechanism to regulate the circadian transcriptome. Posttranslational modifications of core clock proteins provide precise temporal control over when they are active as regulators of clock-controlled genes. In particular, phosphorylation is a key regulatory mechanism that dictates the subcellular localization, stability, and transcriptional activity of clock proteins. Previously, casein kinase 1α (CK1α) has been identified as a kinase that phosphorylates mammalian PER1 and modulates its stability, but the mechanisms by which it modulates PER protein stability is still unclear. UsingDrosophilaas a model, we show that CK1α has an overall function of speeding up PER metabolism and is required to maintain the 24 h period of circadian rhythms. Our results indicate that CK1α collaborates with the key clock kinase DOUBLETIME (DBT) in both the cytoplasm and the nucleus to regulate the timing of PER-dependent repression of the circadian transcriptome. Specifically, we observe that CK1α promotes PER nuclear localization by antagonizing the activity of DBT to inhibit PER nuclear translocation. Furthermore, CK1α enhances DBT-dependent PER phosphorylation and degradation once PER moves into the nucleus.SIGNIFICANCE STATEMENTCircadian clocks are endogenous timers that integrate environmental signals to impose temporal control over organismal physiology over the 24 h day/night cycle. To maintain the 24 h period length of circadian clocks and to ensure that circadian rhythms are in synchrony with the external environment, key proteins that make up the molecular oscillator are extensively regulated by phosphorylation to ensure that they perform proper time-of-day-specific functions. Casein kinase 1α (CK1α) has previously been identified as a kinase that phosphorylates mammalian PERIOD (PER) proteins to promote their degradation, but the mechanism by which it modulates PER stability is unclear. In this study, we characterize the mechanisms by which CK1α interacts with DOUBLETIME (DBT) to achieve the overall function of speeding up PER metabolism and to ensure proper time-keeping.

Published: October 2018

For many animals, target motion carries high ecological significance as this may be generated by a predator, prey, or potential mate. Indeed, animals whose survival depends on early target detection are often equipped with a sharply tuned visual system, yielding robust performance in challenging conditions. For example, many fast-flying insects use visual cues for identifying targets, such as prey (e.g., predatory dragonflies and robberflies) or conspecifics (e.g., nonpredatory hoverflies), and can often do so against self-generated background optic flow. Supporting these behaviors, the optic lobes of insects that pursue targets harbor neurons that respond robustly to the motion of small moving objects, even when displayed against syn-directional background clutter. However, in diptera, the encoding of target information by the descending neurons, which are more directly involved in generating the behavioral output, has received less attention. We characterized target-selective neurons by recording in the ventral nerve cord of male and female predatoryHolcocephala fuscarobberflies and of male nonpredatoryEristalis tenaxhoverflies. We show that both species have dipteran target-selective descending neurons that only respond to target motion if the background is stationary or moving slowly, moves in the opposite direction, or has un-naturalistic spatial characteristics. The response to the target is suppressed when background and target move at similar velocities, which is strikingly different to the response of target neurons in the optic lobes. As the neurons we recorded from are premotor, our findings affect our interpretation of the neurophysiology underlying target-tracking behaviors.SIGNIFICANCE STATEMENTMany animals use sensory cues to detect moving targets that may represent predators, prey, or conspecifics. For example, birds of prey show superb sensitivity to the motion of small prey, and intercept these at high speeds. In a similar manner, predatory insects visually track moving prey, often against cluttered backgrounds. Accompanying this behavior, the brains of insects that pursue targets contain neurons that respond exclusively to target motion. We here show that dipteran insects also have target-selective descending neurons in the part of their nervous system that corresponds to the vertebrate spinal cord. Surprisingly, and in contrast to the neurons in the brain, these premotor neurons are inhibited by background patterns moving in the same direction as the target.

Introduction: Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder. Treatment can improve symptoms and social functioning in the patients. This study was designed to assess the effect of adding Luvos supplementation to mebeverine on improving symptoms and quality of life (QOL) in patients with diarrhea-predominant irritable bowel syndrome.
Methods: Eighty patients with diarrhea-predominant IB, ages 18-65, were diagnosed by the Rome IV criteria and randomly assigned to the study. Forty patients (group A) received mebeverine (135 mg) twice a day (bid) plus Luvos®Healing Earth (1 sachet, bid). The other 41 patients (group B) received mebeverine (135 mg) bid for 4 weeks. Basic demographic data, Bristol score, symptom severity score, and QOL questionnaire were recorded at the start and completion of treatment. The data were analyzed by SPSS version 22.
Results: Seventy one of the patients (35 and 36 patients in groups A and B, respectively) completed the study. The majority of the patients were young males, unmarried and highly educated. Diarrhea and QOL were both significantly improved in group A when compared to group B (P=0.036 and P=0.028, respectively). We did not find a significant difference (improvement) in abdominal pain or overall symptom score between group A (mebeverine + Luvos) compared to group B (mebeverine alone) (P=0.096 and P=0.071, respectively). Mild and tolerable adverse effects were observed in 2.8% (2/71) of the patients.
Conclusion: According to our results, Luvos supplementation is safe, effective and well-tolerated in diarrhea-predominant irritable bowel syndrome patients. Further study with a larger sample size is recommended to evaluate the efficacy of this natural clay-like medicine.

Authors: Nguyen Phuoc T. , Pham Trung D. , Hoang Hoa P. 
Published: October 2018

The influence of foundation mass on the dynamic response of track-vehicle interaction is studied in this paper. The moving vehicle is modeled as a two-axle mass-spring-damper four-degrees-of-freedom system. A new dynamic foundation model, called "Dynamic foundation model" including linear elastic spring, shear layer, viscous damping and foundation mass parameter, is used to analyze the dynamic response of the track-vehicle interaction. The railway track on the new dynamic foundation model subjected to a moving vehicle is regarded as an integrated system. By means of the finite element method and dynamic balance principle, the governing equation of motion for railway track-vehicle-foundation interaction is derived and solved by the step-by-step integration method. The accuracy of the algorithm is verified by comparing the numerical results with the other numerical results in the literature. The influence of foundation mass parameter on the dynamic response of railway track-vehicle interaction is investigated. The numerical results show that with the new dynamic foundation model the foundation mass effects more significantly on the dynamic response of track-vehicle interaction. The study shows that the new dynamic foundation model describes the true behavior of soil in the analysis of dynamic response of structures on the foundation.
