Ameloblastoma of the Lower Jaw: A Case Report
Authors: Trajković Miloš , Krasić Dragan , Spasić Milan , Krstić Miljan , Stojanović Miloš , Lazić Vojkan 
Published: November 2016

Summary
Ameloblastoma, a semi-benign odontogenic tumor, is divided into four subtypes based on the clinical presentation, radiological manifestations and histological characteristics. Radiologically, it manifests itself in the form of uni- or multicystic intrabony expansive lesions, with destruction of the medullary zone of the existing bone, resorption and possible perforation of the buccal and lingual cortex.
The patient, a 62-year-old woman, came to the Clinic for Maxillofacial Surgery in Niš with an anamnestically present painless tumefaction in the anterior segment of the mandible present for the past three years. In the course of an intraoral examination in the region of symphysis and parasymphysis of the lower jaw on the left side, an oval-shaped tumor was spotted, 5x3 cm in size; palpation showed that it was hard, painless and motionless. Multislice computed tomography (MSCT) of the oro - and hypopharynx and neck showed an extensive tumor formation of the soft tissue density in the anterior segments of the lower jaw, with the signs of destruction of bone tissue of the buccal and lingual cortex of the lower jaw.
The frequency of recurrence depends on the histological type of ameloblastoma and the degree of radicalism of the performed surgical intervention. Ameloblastoma in most cases is definitely diagnosed in the advanced stage of the disease due to the absence of symptoms and very slow tumor progression.
Antioxidant defences of Norway spruce bark against bark beetles and its associated blue-stain fungus
Authors: Felicijan Mateja , Novak Metka , Kraševec Nada , Urbanek Krajnc Andreja 
Published: November 2016

Abstract Bark beetles and their fungal associates are integral parts of forest ecosystems, the European spruce bark beetle (Ips typographus Linnaeus, 1758) and the associated pathogenic blue stain fungus Ceratocystis polonica (SIEM.) C. MOREAU, are the most devastating pests regarding Norway spruce [Picea abies (L.) H. KARST.]. Bark beetles commonly inhabit weakened and felled trees as well as vital trees. They cause physiological disorders in trees by destroying a phloem and cambium or interrupt the transpiration -ow in the xylem. Conifers have a wide range of effective defence mechanisms that are based on the inner bark anatomy and physiological state of the tree. The basic function of bark defences is to protect the nutrient-and energy-rich phloem, the vital meristematic region of the vascular cambium, and the transpiration -ow in the sapwood. The main area of defence mechanisms is secondary phloem, which is physically and chemically protected by polyphenolic parenchyma (PP) cells, sclerenchyma, calcium oxalate crystals and resin ducts. Conifer trunk pest resistance includes constitutive, inducible defences and acquired resistance. Both constitutive and inducible defences may deter beetle invasion, impede fungal growth and close entrance wounds. During a successful attack, systemic acquired resistance (SAR) becomes effective and represents a third defence strategy. It gradually develops throughout the plant and provides a systemic change within the whole tree’s metabolism, which is maintained over a longer period of time. The broad range of defence mechanisms that contribute to the activation and utilisation of SAR, includes antioxidants and antioxidant enzymes, which are generally linked to the actions of reactive oxygen species (ROS). The presented review discusses the current knowledge on the antioxidant defence strategies of spruce inner bark against the bark beetle (Ips typographus) and associated blue stain fungus (Ceratocystis polonica).

Published: November 2016

Abstract Sweet maize is an underutilized vegetable in European temperate areas, and its consumption is increasing. For better understanding of cultivation practices, this pot experiment aimed to determine the eff­ects of diff­erent water regimes and nitrogen (N) rates calculated from N target values. N rates of 0 (control), 0.6 and 2 g N pot-1 were applied as organic by-products pumpkin cake and pig manure digestate, and mineral fertilizers CAN 27 and ENTEC®26. Treatments of water supply were based on measured soil matric potentials of 2.8 pF (drought stress), 2.6 pF (optimal water) and 2.4 pF (overwatered). In comparison to mineral fertilizers, pumpkin cake proved to be equal in eff­ectiveness in plant height (155.8 cm), cob (85.8 g), green (124.9 g) and leaf mass per plant (44.2 g), or even better in root (72.3 g) and broom mass per plant (3.0 g). Yield parameters, cob mass (70.1 g), its length (6.3 cm) and diameter (2.0 cm), as well as the residual mineral N (59 mg N kg-1) significantly increased at the highest N rate. Significantly lower values of the evaluated morphological parameters and photosynthetic rates (at brooming and harvesting) were associated with drought stress. The matric tension of 2.6 pF was established as an appropriate water regime for sweet maize growth.
Radiative effects for some bidimensional thermoelectric problems
Authors: Consiglieri Luisa 
Published: November 2016

Abstract
There are two main objectives in this paper.
One is to find sufficient conditions to ensure the existence
of weak solutions for some bidimensional thermoelectric problems.
At the steady-state, these problems consist
of a coupled system of elliptic equations of the divergence form,
commonly accomplished with nonlinear radiation-type conditions
on at least a nonempty part of the boundary of a

domain.
The model under study takes
the thermoelectric Peltier and Seebeck effects into account,
which describe the Joule–Thomson effect.
The proof method requires a fixed point argument.
To this end, well-determined estimates are our main concern.
The second objective of the paper is
the derivation of explicit

for solutions of nonlinear radiation-type problems

In particular, the behavior of the leading coefficient is
conveniently explicit on the estimate of any solution.
Analysis of Social Conflicts in Poland’s Soundscape as a Challenge to Socio-Acoustics
Authors: Bernat Sebastian 
Published: November 2016

Abstract
The study objective was to understand the character and location of social conflicts in Poland’s soundscape. The analyses were based on a review of press and Internet articles from the years 2008-2015 and reports on noise, preceded by a review of the legal framework of protection against noise in Poland. Questionnaire surveys concerning Poland’s national parks and health resorts and the city of Lublin were an additional source of information. In the case of the former, the surveys were supplemented with a general examination of the acoustic determinants of social conflicts in the Podzamcze district.
An analysis shows that sound in landscape has been a source of more than 100 social conflicts which were most frequently related to unpleasant sounds (noise nuisance) and the right to peace and quiet. The public demands acoustic comfort, one of the determinants of the quality of life. Therefore, it is necessary to know the public opinion on soundscapes (survey of sound preferences). Public consultations concerning the assessment of acoustic disturbance and sound preferences will make it possible to avoid social conflicts arising from insufficient knowledge. A major role is also played by the education of the public and decision-makers through sound awareness campaigns, e.g. as p art of ecology education. The subjective assessment of noise nuisance severity and the acoustic design of public spaces should be an integral part of environmental noise control programmes and revitalisation programmes.
The conducted studies demonstrated that understanding the character and location of social conflicts in soundscape is a major scientific problem. Its resolution requires combining sociological studies (questionnaire for the valuation of the subjective feelings of respondents) with field analyses (observations, acoustic measurements). It is a promising research field that has been developed to a limited extent so far.
Subjective Evaluation of Three Headphone-Based Virtual Sound Source Positioning Methods Including Differential Head-Related Transfer Function
Authors: Storek Dominik , Rund Frantisek , Marsalek Petr 
Published: November 2016

Abstract
This paper analyses the performance of Differential Head-Related Transfer Function (DHRTF), an alternative transfer function for headphone-based virtual sound source positioning within a horizontal plane. This experimental one-channel function is used to reduce processing and avoid timbre affection while preserving signal features important for sound localisation. The use of positioning algorithm employing the DHRTF is compared to two other common positioning methods: amplitude panning and HRTF processing. Results of theoretical comparison and quality assessment of the methods by subjective listening tests are presented. The tests focus on distinctive aspects of the positioning methods: spatial impression, timbre affection, and loudness fluctuations. The results show that the DHRTF positioning method is applicable with very promising performance; it avoids perceptible channel coloration that occurs within the HRTF method, and it delivers spatial impression more successfully than the simple amplitude panning method.
Calculation Models for Acoustic Analysis of St. Elizabeth of Hungary Church in Jaworzno Szczakowa
Authors: Kosała Krzysztof 
Published: November 2016

Abstract
In parallel with research conducted using conventional methods, a uniform index method for assessing the acoustic quality of Roman Catholic churches has been developed. The latest version of the index method has been created using the index observation matrix of 12 churches which have been rated by means of the single number global index.
Assessments of the acoustic quality of any Roman Catholic church, using two calculation models: the Global Acoustic Properties Index (GAP) and the Global Index (GI), are shown in the article. The verification was performed on the example of one church, showing the way of calculating global indices to assess the acoustic quality of a new facility. The next stages in the development of the index method for assessing the acoustic quality of churches were taking into account the audience, using simulation tests and determining the spatial distribution of the single number GAP index in an examined church. An attempt to use the GAP and GI calculation models to assess the acoustic properties of some churches is also shown in the article.
Diagnostics of Rotor Damages of Three-Phase Induction Motors Using Acoustic Signals and SMOFS-20-EXPANDED
Authors: Glowacz Adam 
Published: November 2016

AbstractA fault diagnostics system of three-phase induction motors was implemented. The implemented system was based on acoustic signals of three-phase induction motors. A feature extraction step was performed using SMOFS-20-EXPANDED (shortened method of frequencies selection-20-Expanded). A classification step was performed using 3 classifiers: LDA (Linear Discriminant Analysis), NBC (Naive Bayes Classifier), CT (Classification Tree). An analysis was carried out for incipient states of three-phase induction motors measured under laboratory conditions. The author measured and analysed the following states of motors: healthy motor, motor with one faulty rotor bar, motor with two faulty rotor bars, motor with faulty ring of squirrel-cage. Measured and analysed states were caused by natural degradation of parts of the machine. The efficiency of recognition of the analysed states was good. The proposed method of fault diagnostics can find application in protection of three-phase induction motors.
Numerical Study of Forced Vibration Suppression by Parametric Anti-Resonance
Authors: Pešek Ludek , Šulc Petr , Půst Ladislav 
Published: November 2016

AbstractThe parametric anti-resonance phenomenon as an active damping tool for suppression of externally excited resonant vibration is numerically studied herein. It is well known fact that the anti-resonance phenomenon, i.e. the stiffness periodic variation by subtractive, combination resonance frequency, brings stabilization and cancelling into self-excited vibrations. But this paper aims at a new possibility of its application, namely a damping of externally excited resonant vibration. For estimation of its effect we come both from a characteristic exponent of the analytical solution and numerical solution of forced vibration of 2DOF linear system with additional parametric excitation. The amplitude suppression owing to the parametric anti-resonance is studied on several parameters of the system: a depth of parametric excitation, mass ratio, damping coefficient and small frequency deviations from the parametric anti-resonance.

Authors: Piddubniak Olexa , Piddubniak Nadia 
Published: November 2016

Abstract
The sound radiation from vehicles travelling on the city roads with T junction was considered. The wind effect on acoustic field was taken into account. The solution of this problem was found with the help of the integral Fourier transforms and stationary phase method as the superposition of solutions for the cases of vehicles moving along the straight roads and roads with right-angle bend. As an example, the numerical analysis of traffic noise characteristics was carried out for the T junction city road on one of streets in the town of Łodź (Poland).
The New Methodology for Assessing of the Applicability of Elastomeric Materials in the Vibration Isolation Systems of Railway Lines
Authors: Bednarz Jarosław 
Published: November 2016

Abstract
The technical requirements for the determination of physical parameters of vibration isolating material have not been standardized in Europe and Poland yet, which significantly hinders the ability to compare vibration isolating materials offered on the market. Therefore, there is a need for establishing a norm that could be applied both for the determination of the physico-mechanical properties of elastic vibration isolation elements in rail transport for domestic and foreign producers as well as in their selection for application in a specific vibration isolation system. The paper presents a proposal to standardize the methodology of the estimation of vibration isolation materials physical parameters authorized for use in vibration isolation systems used in rail transport. Methodology for measuring the physico-mechanical parameters of vibration isolating material presented in the paper forms uniform test procedure developed based on a fragmentary norms for flexible materials testing. The use of the proposed research methodology enables the creation of a unified database of elastic materials which parameters will be easy to compare, and choice between them will become easier for designers of vibration isolation systems used in rail transport.
Wavelet Packet Transform based Speech Enhancement via Two-Dimensional SPP Estimator with Generalized Gamma Priors
Authors: Sun Pengfei , Qin Jun 
Published: November 2016

Abstract
Despite various speech enhancement techniques have been developed for different applications, existing methods are limited in noisy environments with high ambient noise levels. Speech presence probability (SPP) estimation is a speech enhancement technique to reduce speech distortions, especially in low signalto-noise ratios (SNRs) scenario. In this paper, we propose a new two-dimensional (2D) Teager-energyoperators (TEOs) improved SPP estimator for speech enhancement in time-frequency (T-F) domain. Wavelet packet transform (WPT) as a multiband decomposition technique is used to concentrate the energy distribution of speech components. A minimum mean-square error (MMSE) estimator is obtained based on the generalized gamma distribution speech model in WPT domain. In addition, the speech samples corrupted by environment and occupational noises (i.e., machine shop, factory and station) at different input SNRs are used to validate the proposed algorithm. Results suggest that the proposed method achieves a significant enhancement on perceptual quality, compared with four conventional speech enhancement algorithms (i.e., MMSE-84, MMSE-04, Wiener-96, and BTW).
Reflections on internet research ethics from language-focused research on web-based mourning: revisiting theprivate/publicdistinction as a language ideology of differentiation
Authors: Giaxoglou Korina 
Published: November 2016

AbstractThe present article addresses ethical issues and tensions that have arisen in the context of language-focused research on web-based mourning. It renders explicit the process of ethical decision-making in research practice, illustrating key aspects of a process approach to research ethics, which calls for reflection on ethical issues as an integral and dynamic part of the project (Markham and Buchanan 2015. Ethical considerations in digital research contexts. In James Wright (ed.)Encyclopedia for Social & Behavioral Sciences. Elsevier Press. 606–613; Page et al. 2014.Researching Language and Social Media: A student guide. Oxon: Routledge). In addition, the article draws attention to some vexing ethical tensions raised in research practice and, in particular, to the uses of the termsprivateandpublicin research ethics frameworks and in discipline-specific discussions. Based on Gal’s (2005. Language ideologies compared: metaphors of public/private.Journal of Linguistic Anthropology15 (1): 23–38) semiotic investigation of the private/public opposition, it is shown how the two categories are used as a language ideology of differentiation that discursively contrasts spaces and forms of emotional communication. It is argued that such metaphorical uses of the terms limit their currency in internet research on language, mourning, and death online, which tends to feature the construction and staging of apublic selfin semi-public contexts. The article concludes with a discussion of the implications of the issues raised in language-focused research on web-based mourning for research ethics as method (Markham 2004. Method as ethic, ethic as method.Journal of Information Ethics15 (2): 37–55) and calls for the critical study of the key concepts that underlie research ethics stances as a key step in rethinking – or ‘undoing’ – ethics (Whiteman 2012.Undoing Ethics: Rethinking Practice in Online Research. London: Springer).

Abstract

Background:
Infections from microorganisms and parasites have been connected with either increased or decreased cancer risk. The objective of this study was to investigate whether infection by Echinococcus granulosus is associated with cancer risk.

Methods:
We assembled a pilot retrospective cohort of patients who were diagnosed as being infected by E. granulosus in Cyprus between 1930 and 2011. Age/gender-matched non-infected family members and neighbors were selected as references. Medical history was ascertained from each study subject through in-person interview. Cox proportional hazards regression analysis was performed to assess the association of being infected by E. granulosus with cancer risk.

Results:
Individuals with prior infection by E. granulosus (n=249) were more likely to have cancer compared to those without infection (n=753), 11.65% vs. 8.37% (p=0.0492). Survival analysis also showed that subjects with prior infection had a higher risk for developing cancer. The hazards ratio (HR) was 1.595, [95% confidence interval (CI) between 1.008 and 2.525]. The risk ratio did not change significantly (HR=1.536; 95% CI: 0.965–2.445) after adjusting for gender, year of birth, smoking status, alcohol consumption, and family history of cancer.

Conclusions:
Our study suggests that infection by E. granulosus may increase cancer risk. If this observation can be confirmed independently, further investigation of the mechanisms underlying the association is warranted.
Réseaux indépendants de télévision en Italie
Authors: Cavalli-Sforza Francesco , Donati Agnese , Evans Huw 
Published: November 2016

Zusammenfassung
Als die Presse zum ersten Mal von dem Aufkommen von Fernsehmaterial zu niedrigem Preis und dessen Konsequenzen für das Regionalfernsehen in Italien berichtete, glaubte man allgemein, dieses würde die aktuellen Tendenzen im Bereich der Kommunikation revolutionieren. Viele dachten, daß das neue Kommunikationsmittel eine Handhabung der Kommunikationsnetze durch und für die lokalen Gemeinwesen ermöglichen würde. Es schien, daß diese Art des Netzes wirtschaftlich wäre, und nicht auf ein hochqualifiziertes, spezialisiertes Personal zurückgreifen müßte. Indem es lokal produziertes Material dem Hauptstrom der von der Regierung betriebenen Netze hinzufügte, könnte es ein Instrument einer ungleichen Macht für die Entwicklung der Gemeinschaft und die sozialen Veränderungen werden. Aber es ist anders gekommen, da von den fünfzig heute in Betrieb befindlichen unabhängigen Netzen einige zu strikt kommerziellen Unternehmen geworden sind, die sich nicht im geringsten um die sozialen Aspekte dieses Informationsorgans kümmern; andere versuchen, lokale Informationsdienste zu liefern, wenn auch auf sehr traditionelle Weise. Nur ein winziger Prozentsatz kann als Instrument für die Gemeinschaftsentwicklung eingestuft werden. Diese Studie schildert kurz die Geschichte vom Aufkommen des Regionalfernsehens und erörtert einige Aspekte des Phänomens und seiner aktuellen Situation.

Senderfärbung und kulturelle Entwicklung
Authors: Blaukopf Kurt 
Published: November 2016

Zusammenfassung
Welchen Beitrag zur kulturellen Entwicklung kann die Programmstrategie und das Programmschema des Hörfunks leisten? Diese Frage wird am Beispiel der sogenannten „Senderfärbung“ behandelt. Unter „Senderfärbung“ wird eine Programmstrategie verstanden, die einzelnen Kanälen bestimmte Programminhalte zuordnet (z. B. vorwiegend Unterhaltungsmusik oder „ernste“ Musik). Aus vorliegenden empirischen Untersuchungen wird abgeleitet, daß die Senderfärbung der kulturellen Kohäsion und der kulturellen Entwicklung abträglich ist.
