Digestive enzymes in Rhinolophus euryale (Rhinolophidae, Chiroptera) are active also during hibernation
Authors: Maxinová Edita , Šustr Vladimír , Uhrin Marcel 
Published: November 2017

AbstractDuring the winter, bats use hibernation as a means of surviving the period of low prey offer. However, the Mediterranean horseshoe bat (Rhinolophus euryale) arouses from torpor quite frequently. Based on the actual climatic conditions, it can profit from occasional foraging oportunities, when they occur. We analysed faeces collected on four nights during the period from November 2012 to February 2013 from the Domica-Baradla cave system (Slovakia and Hungary). In mid-November, the largest proportion of faecal contents were from Lepidoptera. Later on, the proportion of non-consumptive mass in the faeces increased and prey remnants disappeared. We analysed the activity of digestive enzymes (amylase, chitobiase, endochitinase and glukosaminidase) in faeces. The activity of these enzymes was detected in fresh faeces throughout the whole winter. The faecal activity of the chitinases was relatively stable during the monitored period, whilst the activity of amylase was highest during late November and December. Some level of active digestive enzymes during the winter could be an adaptation to occasional winter foraging.

Published: November 2017

Abstract
Agriculture of the Republic of Serbia is a significant economic branch, due to the specifics of production, tradition and because of the enormous potential that it holds for improving competitive performance and development of the national economy. For this reason, in all strategic documents agriculture is recognised as a vital branch for the development of the national economy, which can be achieved by an increase in productivity and greater foreign exchange, especially with the neighbouring countries. Bearing in mind that agricultural food products represent a very important part of foreign trade of the Republic of Serbia with the countries of the Western Balkans, the goal of the research is to point out the comparative advantages of the Republic of Serbia in the exchange of agricultural and food products with the countries in the region, by applying the Balassa index. The realisation of the principal objective of the research was carried out using the methods of comparative advantage, historical method, trends method, methods of analysis and synthesis. The results of research show that the Republic of Serbia has distinct comparative advantages in relation to the countries in the Western Balkans, with the exception of the Republic of Croatia. The key contribution of this paper lies in providing a clearer insight into the comparative advantages of the Republic of Serbia in foreign trade with the countries in the region, as well as pointing out the priority directions of activities of competent authorities in order to intensify. the agricultural export, especially high quality and products at a higher level of processing.
Evaluation of European Cranberrybush (Viburnum opulus L.) genotypes for agro-morphological, biochemical and bioactive characteristics in Turkey
Authors: Ersoy Nilda , Ercisli Sezai , Gundogdu Muttalip 
Published: November 2017

AbstractThe study evaluated some agro-morphological (fruit weight, fruit flesh ratio, fruit skin colour, number of fruits per raceme, number of racemes per bush), biochemical (vitamin C, soluble solids content, organic acids), and bioactive (total phenolics, total anthocyanins, total flavonoids, and antioxidant capacity) characteristics of the fruit of a number of selected European Cranberrybush (Viburnum opulus L.) genotypes grown in the Sivas province of Turkey. To evaluate the antioxidant capacity, ferric reducing antioxidant power (FRAP) assays were performed. The results showed genotype-specific differences in most of the agro-morphological, biochemical and bioactive characteristics. The range of fruit weight, number of fruits per raceme, and number of racemes per bush was between 0.67 and 0.82 g, 40.7 and 57.1, and 470 and 581, respectively. The highest vitamin C and soluble solids contents were found in the fruits of genotypes SIV-9 and SIV-6 as 39 mg per 100 g and 12.6%, respectively. Tartaric acid was the main organic acid in all the genotypes; it ranged from 120 to 144 mg per 100 g of fruit FW. Total phenolic, total anthocyanin and total flavonoid contents ranged from 621 to 987 mg gallic acid equivalents per 100 g, 15 to 51 mg cyanidin-3-rutinoside equivalents per 100 g, and 202 to 318 mg rutin equivalents per 100 g, respectively. Genotype SIV-10 had the highest antioxidant capacity (34.90 μmol Trolox per g, based on FRAP assays). The present study shows the potential of the evaluated European Cranberrybush genotypes for improving the nutritional value through germplasm enhancement programmes.

Authors: Taş Emre , Yurdakadim Tugba 
Published: November 2017

Abstract
In this paper, using the concept of ideal convergence, which extends the idea of ordinary convergence and statistical convergence, we are concerned with the I-uniform convergence and the I-pointwise convergence of sequences of functions defined on a set of real numbers D.
We present the Arzelà–Ascoli theorem by means of ideal convergence and also the relationship between I-equicontinuity and I-continuity for a family of functions.

Identification and management of familial breast cancer in Austria
Authors: Singer Christian F. , Tan Yen Y. , Rappaport Christine 
Published: November 2017

Abstract

Aim
The aim of this study is to review the legal implications, the technology, the indications and the management of women with a familial background of breast and/or ovarian cancer.

Methods
We have reviewed the literature and national Austrian guidelines to describe the uptake of genetic counseling and the management options offered in Austria.

Results
Genetic testing for the BRCA1 and 2 mutations is free and readily available through a nation-wide program. Increased awareness and the availability of screening programs and prophylactic surgery have resulted in a profound increase in genetic counseling and testing in women with a familial background of breast and ovarian cancer in Austria.

Conclusion
While readily available country-wide counseling has led to an increase in counseling and testing, Austrian legislation mandates “non-directional counseling” resulting in a comparatively low uptake of prophylactic surgery.
Study on a Novel Bearing Fault Diagnosis Method from Frequency and Energy Perspective
Authors: Li Xiumei , Liu Yong , Zhao Huiming , Deng Wu 
Published: November 2017

AbstractEarly identification of faults in rolling element bearings is a challenging task; especially extracting transient characteristics from a noisy signal and identifying bearings fault become critical steps. In this paper, a novel method for real time fault detection in rolling element bearings is proposed to deal with non-stationary fault signals from frequency and energy perspective. Second-order blind identification (SOBI) and wavelet packet decomposition are organically integrated to diagnose the early bearing faults, the fault vibration signals are processed by SOBI algorithm, and feature information is extracted; meanwhile, fault vibration signals are decomposed by the wavelet packet, the energy of terminal nodes(at the bottom layer of wavelet packet decomposition) are analyzed because the energy of terminal nodes has different sensitive to different component faults. Therefore, the bearing faults can be diagnosed by organic combination of fault characteristic frequency analysis and energy of the terminal nodes, and the effectiveness, feasibility and robustness of the proposed method have been verified by experimental data.

Experiencing Oppression: Ventriloquism and Epistemic Violence in Practical Theology
Authors: Goto Courtney T. 
Published: November 2017

AbstractEpistemic violence, an experience of oppression felt from the inside, is ever-present and thus present throughout the academy. This paper explores the experience of epistemic violence in practical theology, where we are given institutional authority to interpret and represent the lived experiences of others. I use the metaphor of ventriloquism to explore practical theologians as performers who, by virtue of our position, make dummies of those we are attempting to serve, including subjects of research, faith communities, and students.
Bioethics and Practical Theology: The Example of Reproductive Medicine
Authors: Messer Neil 
Published: November 2017

AbstractThis report begins by introducing bioethics, outlining the history and present shape of the field, and making some brief remarks about its methods and approaches. The interactions of theology and religion with bioethics are briefly surveyed, and potential points of contact with practical theology are identified. Next, the ethics of reproductive medicine, in particular in vitro fertilisation (IVF), is used as a specific example of theological reflection on bioethics. The final section identifies some questions arising from this example, which may contribute to a research agenda in bioethics and practical theology.

Authors: Soni G. 
Published: November 2017

Abstract
Background: Orthogonal Frequency Division Multiplexing (OFDM) has emerged as the core technology of the 4th generation mobile communication due to its capacity to combat channel fading also OFDM is highly spectral efficient. Methods/Statistical Analysis: LabVIEW 2012 is used to simulate and evaluate the performance of OFDM link. Bit Error Rate (BER) evaluation of discrete Fourier transform (DFT) based OFDM system is carried out in this work. The simulation based analysis is demonstrated by means of different modulation schemes like QPSK, 16-QAM for OFDM based wireless system. Findings: QPSK needs less SNR as compared to 16-QAM to achieve an acceptable BER Furthermore, the efficiency of OFDM increases with increase of cyclic prefix. In OFDM, ISI and ICI-interference reduced by implying cyclic prefix. Applications/Improvements: The performance analysis of orthogonal frequency division multiplexing is analyzed using LabVIEW 2012 based on performance parameters like cyclic prefix simulated at frequency of 2.4 GHz using FFT size 512, 1024.
Robust decentralized power system controller design: Integrated approach
Authors: Veselý Vojtech 
Published: November 2017

Abstract
A unique approach to the design of gain scheduled controller (GSC) is presented. The proposed design procedure is based on the Bellman-Lyapunov equation, guaranteed cost and robust stability conditions using the parameter dependent quadratic stability approach. The obtained feasible design procedures for robust GSC design are in the form of BMI with guaranteed convex stability conditions. The obtained design results and their properties are illustrated in the simultaneously design of controllers for simple model (6-order) turbogenerator. The results of the obtained design procedure are a PI automatic voltage regulator (AVR) for synchronous generator, a PI governor controller and a power system stabilizer for excitation system.
Existence of variational source conditions for nonlinear inverse problems in Banach spaces
Authors: Flemming Jens 
Published: November 2017

Abstract
Variational source conditions proved to be useful for deriving convergence rates for Tikhonov’s regularization method and also for other methods.
Up to now, such conditions have been verified only for few examples or for situations which can be also handled by classical range-type source conditions.
Here we show that for almost every ill-posed inverse problem variational source conditions are satisfied.
Whether linear or nonlinear, whether Hilbert or Banach spaces, whether one or multiple solutions, variational source conditions are a universal tool for proving convergence rates.
Automatic Gain-Controlled HOA with Residual Pumping
Authors: Singh Navjot , Kumar Mahendra , Verma Ashu 
Published: November 2017

AbstractThe interminable need of number of channels in communication systems escorts more number of wavelengths to be used. This broad spectrum of wavelengths when expands in both C and L band, the need of hybrid optical amplifiers (HOA) comes into play. In this work, we proposed an automatic gain-controlled HOA using Residual pumping for C/L band. The desired gain is fixed at 27 dB at pump power swinging between 300 and 400 mW. The input powers are automatically adjusted so as to provide invariable and flat gain eliminating the wavelength dependency of optical amplifier to great extents. Analysis is carried out in a 32 channel WDM system and power transients are also measured in terms of powers of surviving channels and excursion amplitudes by adding and dropping up to 28 channels. The output is adjudicated in terms of maximum gain achieved, OSNR, BER, gain flatness, noise figure and power transient excursion amplitudes.
Phylogenetic study of H5 low pathogenic avian influenza viruses detected in wild birds in Poland in 2010−2015
Authors: Świętoń Edyta , Śmietanka Krzysztof 
Published: November 2017

Abstract

Introduction: The genomes of nine H5 subtypes of low pathogenic avian influenza virus (LPAIV) strains identified in wild birds in Poland between 2010 and 2015 were sequenced, and their phylogenetic relationship was determined.

Material and Methods: AIV genome segments were amplified by RT-PCR and the PCR products were sequenced using Sanger method. Phylogenetic trees were generated in MEGA6 software and digital genotyping approach was used to visualise the relationship between analysed strains and other AIVs.

Results: High genetic diversity was found in the analysed strains as multiple subgroups were identified in phylogenetic trees. In the HA tree, Polish strains clustered in two distinct subclades. High diversity was found for PB2, PB1, PA and NP, since 5-8 sublineages could be distinguished. Each strain had a different gene constellation, although relationship of as much as six out of eight gene segments was observed between two isolates. A relationship with poultry isolates was found for at least one segment of each Polish strain.

Conclusion: The genome configuration of tested strains indicates extensive reassortment, although the preference for specific gene constellation could be noticed. A significant relationship with isolates of poultry origin underlines the need for constant monitoring of the AIV gene pool circulating in the natural reservoir.

Published: November 2017

AbstractIntroduction:Eight microsatellite loci were used to define genetic diversity among five native water buffalo breeds in Pakistan.Material and Methods:Blood samples (10 mL) from 25 buffaloes of each of the Nili, Ravi, Nili-Ravi, Kundhi, and Azi-Kheli breeds were collected aseptically from the jugular vein into 50 ml Falcon tubes containing 200 μl of 0.5 M EDTA. The phenol-chloroform method was used to extract DNA and the regions were amplified for microsatellite analysis. The eight microsatellite markers ETH10, INRA005, ILSTS029, ILSTS033, ILSTS049, ILSTS052, ETH225, and CSSM66 were analysed.Results:The effective number of alleles across all loci was as usual lower than the observed values with a mean value of 2.52 alleles per locus. The overall allele frequency varied from 0.0041 for alleles B, I, and J over respective loci ILSTS052, INRA005, and ILSTS029 to 0.80 for allele H over locus ILSTS029. The average observed and expected heterozygosity values across all polymorphic loci in all studied buffalo breeds were 0.43 and 0.53, respectively. The overall value for polymorphic information content of considered microsatellite markers was 0.53, suggesting their appropriateness for genetic diversity analysis in buffalo. The mean Fis value was 0.13 and all loci except ILSTS049 were found significantly deviated from HWE, most likely due to non-random breeding. The five buffalo populations were genetically less diverse as indicated by a small mean Fst value (0.07). The average gene flow (Nm) indicative for population migration was calculated as 3.31. Nei’s original measures of genetic distance (Ds) revealed ancient divergence of the Nili and Azi-Kheli breeds (Ds = 0.1747) and recent divergence of the Nili and Ravi breeds (Ds = 0.0374).Conclusion:These estimates of genetic diversity were seen to coincide with phenotypic differentiation among the studied buffalo breeds. The present study reports the first microsatellite marker-based genetic diversity analysis in Pakistani buffalo breeds, and might facilitate similar studies in other livestock breeds of Pakistan.
The Visual Power of News Agencies
Authors: Gynnild Astrid 
Published: November 2017

Abstract
While staff photographers are losing their jobs, news agency networks have become main suppliers of visual content to the news media. A global news site such as the Guardian leans to news agencies for most of its selected visuals. In tandem with the expanding visual power of new agencies, the ethical standards of the wholesalers are challenged by increasing amounts of user generated content, distant editing, and the live-streaming of breaking news. This article discusses editorial dilemmas prompted by proliferate, high tech processing of visual content by the news agencies’ global networks, exemplified by the coverage of terrorism. The analysis is grounded in a variety of empirical data, and aspects of Manuel Castells’ theory on communication power provide a theorizing framework for the discussion. The study suggests that the visual power of today’s news agencies rests on three interconnected processes of handling imagery: agency infrastructuring, technological infrastructuring and global newsroom infrastructuring.
Holm Tetens on the Moral-Existential Argument for Theism: Reasonable Hope and Wishful Thinking
Authors: Gasser Georg 
Published: November 2017

SummaryHolm Tetens develops in his book „Gott denken. Ein Versuch über rationale Theologie“ theoretical and practical arguments against a naturalistic and in favour of a theistic understanding of reality. In my paper I focus on Teten’s claim that we are rationally justified to hope for the truth of classical theism. I distinguish between rationally justified and unjustified forms of hope and argue that we are rationally justified to hope for the redemption of reality as promised by classical theism. However, this hope has a weaker basis of justification than Tetens seems to assume because serious objections to classical theism ought to be taken into consideration as well.
Metal–metal bonding in deltahedral dimetallaboranes and trimetallaboranes: a density functional theory study

n−2H
n−2 (Cp*=η5Me5C5, n=8–12) suggest formal Re=Re double bonds through the center of a flattened Re2B
n−2 deltahedron. Removal of a boron vertex from these oblatocloso structures leads to oblatonido structures such as Cp2W2B5H9 and Cp2W2B6H10. Similar removal of two boron vertices from the Cp2Re2B

n−2H
n−2 structures (Pn=η5,η5-pentalene) in which the pentalene ligand forces the rhenium atoms to occupy adjacent deltahedral vertices. The low-energy structures of the tritungstaboranes Cp3W3(H)B

n−3 (n=5–12), related to the experimentally known Cp*3W3(H)B8H8, have central W3B
n−3 deltahedra with imbedded bonded W3 triangles. Similar structures are found for the isoelectronic trirhenaboranes Cp3Re3B
n−3H
n−3. The metal atoms are located at degree 6 and 7 vertices in regions of relatively low surface curvature whereas the boron atoms are located at degree 3–5 vertices in regions of relatively high surface curvature. The five lowest-energy structures for the 11-vertex tritungstaborane Cp3W3(H)B8H8 all have the same central W3B8 deltahedron and differ only by the location of the “extra” hydrogen atom. The isosceles W3 triangles in these structures have two long ~3.0 Å W–W edges through the inside of the deltahedron with the third shorter W–W edge of ~2.7 to ~2.8 Å corresponding to a surface deltahedral edge.
