Published: December 2017

Abstract
The aim of this study was to determine the growth features of European perch (Perca fluviatilis L., 1758) inhabiting Lake Ladik. A total of 858 individuals were caught. The total length and weight ranged from 8.2 to 27.5 cm and from 7.16 to 365.20 g, respectively. The age of the females ranged between 1 and 7 years and the age of the males ranged from 1 to 5 years. The female to male ratio was 1:0.19. The von Bertalanffy growth equation parameters were determined as L
∞=41.27 cm, W
∞=1251.40 g, K=0.10 (year−1), t
0 (year)=−1.98 for all samples. Length-weight relationship was calculated as W=0.0047TL
3.358 for all specimens. Length-length relationships (total length-standard length, total length-fork length, standard length-fork length) were highly significant (r2>0.98). The mean condition factor value was obtained as 1.28 for all fish. Condition factor showed statistically significant increase according to length classes.

Abstract
Allometry, condition index and sex ratio in freshwater mussel Lamellidens corrianus (Lea, 1834) were studied from the freshwater lake at Rajshahi, Northwest Bangladesh during the summer 2013. The collected mussel specimens ranged from 3.69 cm to 9.98 cm in length, and 4.82 g to 80.67 g in weight. The study was focused on the relationships between length-height and length-weights (length-total weight, length-tissue wet weight, length-shell wet weight, length-tissue dry weight and length-shell dry weight), which were found not to be significantly different between male and female (P<0.05). The calculated regression equation of length-height relationship for the entire study period was H= 0.5215L-0.1482 for combined sex. The equations of length-total weight, length-tissue wet weight, length-shell weight, length-tissue dry weight and length-shell dry weight relationships of mussel were W= 0.1756L2.6775, W= 0.0261L2.8919, W= 0.0261L2.5524, W= 0.0065L2.8946 and W= 0.095L2.5109, respectively for combined sex. The relationships between length and height were linear, while that between length-weights follow the non-linear pattern. The overall male to female sex ratio was 1: 0.92 and did not differ significantly from the expected 1: 1 ratio (x
2-test, P<0.05). The condition index for male, female and combined sex was 13.54, 13.97 and 13.74, respectively. The results of this study will provide baseline information for fisheries researchers and for the further assessment and management of mussels in the freshwater ecosystems of Bangladesh.
Effects of Tank Background Colour on Growth Performance and Feed Utilization of African Catfish Clarias Gariepinus (Burchell, 1822) Fingerlings
Authors: Okomoda Victor Tosin , Tiamiyu Lateef Oloyede , Wase Gabriel 
Published: December 2017

Abstract
The performance of Clarias gariepinus (Burchell, 1822) fingerlings reared in white, green, blue, black and red coloured tanks was investigated. Each colour was tested in triplicate 1 m3 tanks with an initial stocking density of 100 fingerlings per tank (1.07 g). Fish were fed a commercial diet at 5% body weight per day for eight weeks. Fish weights were sampled every 2 weeks to adjust feeding rates. Tank colour had a significant effect (P < 0.05) on the overall performance of the fingerlings. Rearing in black tanks resulted in a higher daily feed intake (0.44 g) and better growth performance when compared to other tank colours, while the poorest performance was observed in blue and green tanks. Carcass protein and fat content at 8 weeks revealed a trend similar to that observed for growth. Also, serum glucose tests showed higher levels in light background tanks and were thought to be an indication of stress. Survival was not affected by tank colour. It was concluded that dark-coloured tanks such as black or red were better in comparison to light-coloured tanks for the rearing of African catfish fingerlings

Abstract
A low profile wide slot antenna for dual band and dual sense circular polarization (CP) is proposed here and is simulated by using HFSS simulation software.The proposed antenna having a C shaped patch for dual band operation and a wide square slot etched on the ground with two strips for CP operation. In between radiating patch and ground plane, designed antenna has a layer of easily available dielectric (FR-4) material. Proposed antenna shows an impedance bandwidth of 13.8 % at 2.38 GHz of centre frequency and 9.7 % at 4.43 GHz of centre frequency for lower and upper band respectively. The 3-dB axial ratio (AR) bandwidths for lower and upper band are 18.8 % (at 2.44 GHz of centre frequency) and 13.3 % (at 4.29 GHz of centre frequency), respectively. The peak gain for the lower and upper band is found as 4.1 dBi and 3.3 dBi, respectively. A close agreement has been found between the simulated and the measured results.
Einleitungen interdisziplinär vergleichen
Authors: Szurawitzki Michael 
Published: December 2017

AbstractThe present paper presents the findings of a study comparing the formulations of introductions of academic articles across disciplines. A multidisciplinary corpus of 20 articles from linguistics, medicine, the natural sciences, economics, and sociology is examined. The analysis comprises two general steps, the first being macro-, the second being microstructural. Macrostructurally, the explicit formulations of the moves conducted in the introductions are singled out. These formulations are in turn examined microstructurally in regard to syntax (typology), verbs (valency, grammar-semantics interface, pragmatics) and lexicology (text commentary, lexical deixis, modal expressions). The results are evaluated against the backdrop of possible underlying stylistic patterns of formulation. Subsequently, suggestions for the feasibility of the results within the teaching of German as a (foreign) academic language are made.
The effect of NaOH on the direct calcification–carbonation method for processing of Bayer process red mud
Authors: Xie Liqun , Zhang Tingan , Lv Guozhi , Yang Jinlin , Wang Yanxiu 
Published: December 2017

AbstractThe Bayer red mud generated from the alumina industry is a hazardous solid waste. In our team, a green calcification–carbonation process is proposed for its disposal. Red mud is treated with lime to convert the silicon phase in solution into hydrogarnet, which is then decomposed by CO2to recover alumina. In order to simplify the process flow, the direct carbonation process is employed, in which the NaOH-containing solution resulting from calcification is sent directly to carbonation without prior liquid–solid separation. The discrete and direct carbonation processes gave 34.9% and 35.5% alumina recoveries, respectively, with Na2O contents in the final red muds of 0.15%wt and 0.21%wt, respectively. The optimum NaOH concentration in the whole calcification–carbonation process liquor was 40 g/l. Under this alkali condition, alumina recovery reached 40.5% and the Na2O content in the processed red mud was reduced to <1 %wt.
How to Stay Ahead of the Pack: Optimal Road Cycling Strategies for two Cooperating Riders
Authors: Wolf S. , Saupe D. 
Published: December 2017

Abstract
Within road-cycling, the optimization of performance using mathematical models has primarily been performed in the individual time trial. Nevertheless, most races are 'mass-start' events in which many riders compete at the same time. In some special situations, e.g. breakaways from the peloton, the riders are forced to team up. To simulate those cooperative rides of two athletes, an extension of models and optimization approaches for individual time trials is presented. A slipstream model based on experimental data is provided to simulate the physical interaction between the two riders. In order to simulate real world behavior, a penalty for the difference in the exertion levels of the two riders is introduced. This means, that even though both riders aim to be as fast as possible as a group, neither of them should have an advantage over the other because of significantly different levels of fatigue during the ride. In our simulations, the advantage of cooperation of two equally trained athletes adds up to a time gain of about 10% compared to an individual ride.
Performance Estimation using the Fitness-Fatigue Model with Kalman Filter Feedback

Published: December 2017

Abstract
Tracking and predicting the performance of athletes is of great interest, not only in training science but also, increasingly, for serious hobbyists. The increasing availability and use of smart watches and fitness trackers means that abundant data is becoming available, and the interest to optimally use this data for performance tracking and training optimization is great. One competitive model in this domain is the 3-time-constant fitness-fatigue model by Busso based on the model by Banister and colleagues. In the following, we will show that this model can be written equivalently as a linear, time-variant state-space model. With this understanding, it becomes clear that all methods for optimum tracking in statespace models are also directly applicable here. As an example, we show how a Kalman filter can be combined with the fitness-fatigue model in a mathematically consistent fashion. This gives us the opportunity to optimally consider measurements of performance to adapt the fitness and fatigue estimates in a datadriven manner. Results show that this approach is capable of clearly improving performance tracking and prediction over a range of different scenarios.
Conceptualizing politeness in Japanese and Greek
Authors: Fukushima Saeko , Sifianou Maria 
Published: December 2017

AbstractThe main aim of this paper is to investigate how Japanese and Greek female students conceptualize politeness and then compare the findings in order to tease out any cross-cultural similarities and differences. The data is drawn from a questionnaire filled in by two hundred female undergraduates (one hundred from each group). The results show that there are significant similarities as well as some differences. Although research on im/politeness has concentrated almost exclusively on linguistic performance, a significant similarity between the two groups is that politeness is conceptualized as primarily non-linguistic action. Another major similarity is that both groups conceptualize politeness mainly as “consideration to others” and “appropriate behavior,” the former expressed mostly non-linguistically and the latter involving both linguistic and non-linguistic manifestations. Most participants view politeness as conveyed through attentiveness/helping others, respect and empathy. Differences were located mostly in the numbers of participants who mentioned the various subcategories. For example, more Greek participants related a broad sense of “respect” to politeness, whereas more Japanese participants related it to “empathy” and only Japanese participants mentioned “honorifics.” Our participants’ understandings of politeness appear to be in contrast to earlier politeness theories which view politeness as strategic concern for conflict avoidance and closer to current approaches which view it as relational, expressing concern for the needs and feelings of others.
Ritualizing the Use of Coins in Ancient Greek Sanctuaries
Authors: Lykke Anne 
Published: December 2017

AbstractThe article explores aspects of the monetization of the Greek sanctuaries, more specifically how space was created to accommodate coins as objects and their use within the sacred sphere. Except in a limited number of cases, our understanding is still quite fragmented. Where most research has focused on analyzing the coin material or the epigraphic evidence, the intention here is to look more widely at the archaeological evidence connected with coins and coin-related material. This is done in an attempt to appreciate the significance of the progressing monetization and ritualization of the use of coins and in extension to develop an understanding of the possible changes in human behavior in the sanctuaries based on this evidence.
The Identification of Up- and Downstream Industries using Input–Output Tables and a Firm-level Application to Minority Shareholdings
Authors: Bodnar Olivia A. , Buchwald Achim , Weche John P. 
Published: December 2017

Abstract
We present a method for identifying up- and downstream industries in inter-industry datasets via input–output tables. We apply this approach to aggregated European input–output data and present results on identified industry links and their sensitivity to threshold definitions. We furthermore test the time-consistency of the up- and downstream assignments based on input–output tables, and discuss the limitations of this method. Finally, the method is used to test anti-competitive effects of non-controlling minority shareholdings.
How to Make “Colored” Japanese Counter-Reformation Saints – A Study of an Iconographic Anomaly
Authors: Rappo Hitomi Omata 
Published: December 2017

Abstract
The 1627 beatification of the twenty-six martyrs of Japan was a major milestone in the history of the Church and especially for the missionary orders. These martyrs were the first officially recognized saints from the newly “discovered” lands. However, while the majority of the twenty-six were in fact Japanese, surviving paintings depict them as white-skinned missionaries and without any physical features that would have been considered “typically Asian” at the time. This paper analyzes this iconographic tradition and shows how it can be understood as a consequence of a process of assimilation of Christian Japan into the Catholic world view. Associating particular skin color with true faith and civilization was part of discourses that blended the physical “otherness” of these martyrs. This paper demonstrates how these discourses point to the first seeds of a racial perception of East Asians, which would later become the notion of “yellow.”
The Morpho-Functional Parameters of Rat Pituitary Hormone Producing Cells After Genistein Treatment
Authors: Trifunović Svetlana , Milošević Verica 
Published: December 2017

AbstractPhytoestrogens are a diverse group of steroid–like compounds that occur naturally in many plants. There are various types of phytoestrogens, including the best-researched isoflavones which are commonly found in soy. The consumption of soy products has many health benefits, including protection against breast cancer, prostate cancer, menopausal symptoms, heart disease and osteoporosis. In contrast, use of hormonally active compounds-isoflavones may unfortunately interfere with the endocrine system and can have far-reaching consequences. Genistein, the most abundant soy-bean derived isoflavone, possesses a ring system similar to estrogens and acts through an estrogen receptor (ER)-mediated mechanism, by increasing or decreasing the transcription of ER-dependent target genes. Also, genistein can act on cells through ER non-dependent mechanisms, such as tyrosine kinase inhibitor. The neuroendocrine systems are responsible for the control of homeostatic processes in the body, including reproduction, growth, metabolism and energy balance, and stress responsiveness. It is well known, that estrogen is important for development of the neuroendocrine system in both sexes. At the pituitary level, estrogen is known to affect the regulation of all hormone producing (HP) cells, by direct and/or indirect mechanisms. Due to structural and functional resemblance to estrogen, the question may arise of whether and how genistein affects the morphofunctional features of pituitary HP cells. This review deals with the consequences of genistein’s effects on morphological, stereological and hormonal features of HP cells within the anterior pituitary gland. Transparency on this issue is needed because isoflavones are presently highly consumed. Inter alia, genistein as well as other isoflavones, are present in various dietary supplements and generally promoted as an accepted alternative to estrogen replacement therapy. Potential isoflavone biomedical exploitation is not only limited to estrogen replacement therapy, so it should be treated in a wider context of different ageing symptoms remediation.

Published: December 2017

Abstract
Introduction. Insulin resistance is the most common extrahepatic manifestation associated with hepatitis C virus, which leads to developing more pronounced fibrosis and liver steatosis. The aim of the study was to assess the prevalence of insulin resistance in non-diabetic, treatment naive patients with chronic hepatitis C and to analyze the relation of insulin resistance with genotype, viral load, gender, age, laboratory parameters, inflammatory and fibrotic changes in the liver, body mass index (BMI) and the presence of steatosis. Methods. In this cross sectional study, 224 patients with hepatitis C viral infection were included. The patients were divided into two groups. The first group was with no insulin resistance and the second one with present insulin resistance. They were compared in terms of genotype, viral load, gender, age, inflammatory and fibrotic changes in the liver, BMI and liver steatosis. Results. Insulin resistance was present in 45.5% of patients. The following factors were associated with insulin resistance: age (p=0.0022), inflammatory and fibrotic changes in the liver (p=0.001, p=0.006, respectively), steatosis (p=0.015) and transaminase activities (for AST, p=0,002, for ALT, p=0.001). Conclusion. In the Republic of Macedonia, a high percent of 45.5% among non-diabetic and treatment naïve patients with chronic viral hepatitis C, had insulin resistance. Insulin resistance was more prevalent in older patients, in those with more pronounced inflammatory and fibrotic changes in the liver, in patients with steatosis and in those with higher transaminase activity.
Analysis of Properties of an Active Linear Gesture Sensor

Published: December 2017

Abstract
Basic gesture sensors can play a significant role as input units in mobile smart devices. However, they have to handle a wide variety of gestures while preserving the advantages of basic sensors. In this paper a user-determined approach to the design of a sparse optical gesture sensor is proposed. The statistical research on a study group of individuals includes the measurement of user-related parameters like the speed of a performed swipe (dynamic gesture) and the morphology of fingers. The obtained results, as well as other a priori requirements for an optical gesture sensor were further used in the design process. Several properties were examined using simulations or experimental verification. It was shown that the designed optical gesture sensor provides accurate localization of fingers, and recognizes a set of static and dynamic hand gestures using a relatively low level of power consumption.

Published: December 2017

AbstractLightweight and low-cost organic photovoltaics (OPVs) hold great promise as renewable energy sources. The most critical challenge in developing high-performance OPVs is the incomplete photon absorption due to the low diffusion length of the carrier in organic semiconductors. To date, various attempts have been carried out to improve light absorption in thin photoactive layer based on optical engineering strategies. Nanostructure-induced light harvesting in OPVs offers an attractive solution to realize high-performance OPVs, via the effects of antireflection, plasmonic scattering, surface plasmon polarization, localized surface plasmon resonance and optical cavity. In this review article, we summarize recent advances in nanostructure-induced light harvesting in OPVs and discuss various light-trapping strategies by incorporating nanostructures in OPVs and the fabrication processing of the micro-patterns with high resolution, large area, high yield and low cost.
