Authors: He Weikai , Feng Jianxiong , Gao Li , Zhang Zhiwei , Lu Hongwang 
Published: October 2017

AbstractThe Aselliscus Stoliczkanus bat, studied here, has intricately shaped structures surrounding the nostrils. These structures are hypothesised to have influence on animals’ acoustic radiation patterns. Using micro-tomography scanning technique, a 3D digital model of the noseleaf is reconstructed and biosonar beam pattern is analysed using a finite element method based on the 3D noseleaf model. The present research focuses on the conspicuous furrows in noseleaf, and our analysis allows to conclude the followings: a) structural details in noseleaf of Aselliscus Stoliczkanus bat can produce acoustic effects even if it is not adjacent to the nostrils, b) the furrows possess frequency-selective characteristics, c) the furrows have the function to manipulate the direction and width of the outgoing ultrasound wave.

AbstractJournal bearings are widely used to support the shafts in industrial machinery involving heavy loads, such as compressors, turbines and centrifugal pumps. The major problem that could arise in journal bearings is catastrophic failure due to corrosion or erosion and fatigue, which results in economic loss and creates major safety risks. Thus, it is necessary to provide suitable condition monitoring technique to detect and diagnose failures, and achieve cost savings to the industry. Therefore, this paper focuses on fault diagnosis on journal bearing using Debauchies Wavelet-02 (DB-02). Nowadays, wavelet transformation is one of the most popular technique of the time-frequency-transformations. An experimental setup was used to diagnose the faults in the journal bearing. The accelerometer is used to collect vibration data, from the journal bearing in the form of time domain. This was then used as input for a MATLAB code that could plot the time domain signal. This signal was then decomposed based on the wavelet transform. The fast Fourier transform is then used to obtain the frequency domain, which gives us the frequency having the highest amplitude. To diagnose the faults various operating conditions are used in the journal bearing such as Full oil, half loose, half oil, fault 1, fault 2, fault 3 and full loose. Then the Artificial Neural Networks (ANN) is used to classify faults. The network is trained based on data already collected and then it is tested based on random data points. ANN was able to classify the faults with the classification rate of 85.7%. Thus, the test process for unseen vibration data of the trained ANN combined with ideal output target values indicates high success rate for automated bearing fault detection.

Abstract
Noise mapping is a well-established practice among the European nations, and it has been follow for almost two decades. Recently, as per guidelines of the Directorate General of Mines Safety (DGMS), India, noise mapping has been made mandatory in the mining expanses. This study is an effort to map the noise levels in nearby areas of mines in the northern Keonjhar district. The motive of this study is to quantify the existing A-weighted time-average sound level (LAeq,T ) in the study area to probe its effects on the human dwellings and noise sensitive areas with the probability of future development of the mines, roads, and industrial and commercial zone. The LAeq,T was measured at 39 identified locations, including industrial, commercial, residential, and sensitive zones, 15 open cast mines, 3 major highways, and 3 haulage roads. With the utilisation of Predictor LimA Software and other GIS tools, the worked out data is mapped and noise contours are developed for the visualisation and identification of the extent and distribution of sound levels across the study area. This investigation discloses that the present noise level at 60% of the locations in silence and residential zone exposed to significantly high noise levels surpasses the prescribed limit of Central Pollution Control Board (CPCB), India. The observed day and night time LAeq, T level of both zones ranged between 43.2-62.2 dB(A) and 30.5-53.4 dB(A), respectively, whereas, the average Ldn values vary between 32.7 and 51.2 dB(A). The extensive mobility of heavy vehicles adjoining the sensitive areas and a nearby plethora of open cast mines is the leading cause of exceeded noise levels. The study divulges that the delicate establishments like schools and hospitals are susceptible to high noise levels throughout the day and night. A correlation between observed and software predicted values gives R2 of 0.605 for Ld, 0.217 for Ln, and 0.524 for Ldn. Finally, the mitigation measure is proposed and demonstrated using a contour map showing a significant reduction in the noise levels by 0-5.3 dB(A).

Published: October 2017

AbstractTransverse rumble strips (TRS) are a common choice to reduce vehicle speed and increase driver alertness on roadways. However, there is a potential trade-off using them on rural roadway due to the noise problem created when vehicles go over the strips. The present study investigated the noise level, spectral analysis, and the possible noise generation mechanism when the TRS is hit by a vehicle. Tenraised- rumbler (RR) and three-layer-overlapped (TLO) TRS were selected in this study as they have received complaints from the public. Results showed that RR generated a relatively higher noise and impulse at a low speed, and increased sound level in each octave band. Based on these results, RR may irritate human ears even when the vehicle travels at a low speed. It was found that RR increased all noise generation mechanisms of tyre-pavement interaction whilst TLO increased structural resonance, sidewall and surface texture vibration.

AbstractDynamic development of wind power should take into account requirements resulting from environmental protection and human health. However in the case of occupational exposure to noise emitted by wind turbines (workplaces of wind turbine operation personnel, including persons performing maintenance) there are no documented data in literature in this regard. An example of pilot assessments of noise and infrasonic noise at workplaces in a wind farm is presented in the paper. The results of measurements and assessments of noise emitted by the wind turbines Vestas V80-2.0 MW show that noise does not constitute health hazard for wind farm workers. Furthermore infrasonic noise emitted by the wind turbines Vestas V80-2.0 MW is not an annoyance agent for wind farm workers.
The Study of the Proscenium Area in an Opera House
Authors: Sygulska Anna , Brawata Krzysztof 
Published: October 2017

AbstractThe paper describes issues of the proscenium area shown on the example of two opera houses. The subject of the analysis was the design of the Chamber Opera House in Kalisz and the already existing building of the Opera House in Krakow. It covers the influence of the proscenium walls and forestage ceiling on the acoustic conditions in the auditorium. Another subject of the investigation was the influence of the primary proscenium, designed in the very first opera houses in Baroque. The analyses were carried out by means of two computer softwares: Ray Model and Catt Acoustic, and such parameters as sound strength (G), reverberation time (RT), early decay time (EDT), C80(clarity) index and center time (TS) were calculated. The parameters were further analyzed in the auditorium for three positions of the sound source on the stage.
Comparison of Two Types of Combined Measures, STI and U50, for Predicting Speech Intelligibility in Classrooms
Authors: Cho Young-Ji 
Published: October 2017

AbstractThe present study reports on the speech intelligibility as measured by speech transmission index (STI) and useful-to-detrimental sound ratios (U50) in university classrooms. Acoustic measurements were made in 12 quietly occupied university classrooms. The measured impulse responses of the classrooms were used to determine the modulation transfer function, m(F), for the STI calculation according to IEC 60268-16. U50values were determined from both signal-to-noise ratios (SNR) and C50values. The mean STI and frequency-weighted U50values for the 12 occupied classrooms were strongly linearly related. The results showed that classrooms with U50values of about +0.5 dB correspond to STI values of 0.60, indicating ‘good’ acoustical conditions for speech intelligibility. The results illustrate that the U50measure can be a more practically useful means of assessing and understanding room acoustics conditions for real speech communication in active classrooms.
Mindfulness and Complex Identities in Equity Training: A Pilot Study
Authors: Sánchez-Flores Mónica J. 
Published: October 2017

Abstract
Equity (diversity, anti-oppression) training refers to teaching self-awareness of social location, privilege/disadvantage that mainstream culture perpetuates, and working self-reflectively for equity in everyday interactions amid diversity. This paper investigates the efficacy of equity training on the basis of mindfulness, compassion, and an intersectional/complex identity. Mindfulness refers to a vivid awareness of the present moment, of one’s own embodiment, thoughts, and emotions, fostering self-awareness and compassion. A complex conception of identity in an intersectional approach recognizes that people hold multiple statuses and I propose that this helps them self-identify with both privilege and disadvantage beyond dichotomic notions, finger pointing, and angry reactions. I first discuss the relevant theory of intersectionality and compassion, and consider the significance of this kind of approach to equity training. I then report the outcome of my pilot study that compares the impressions of two small groups of trainees in different equity workshops who were interviewed: The target group attended a workshop based on mindfulness exercises within an intersectional framework, and the comparison group attended a workshop not based on mindfulness, but that included information about privilege, disadvantage, and compassion. The findings point to an enhanced and emotionally involved self-awareness in respondents that participated in the target group workshop, based on mindfulness and empathy enhancing exercises.

AbstractBackground:Diabetic nephropathy (DN) is a major microvascular complication of type 2 diabetes mellitus (T2DM). Several lines of evidence implicate the endothelin (ET) system in the pathophysiology of DN. The aim of the present study was to analyze if genetic polymorphisms of the ET-1 (EDN1) gene affect susceptibility to DN in Caucasians with T2DM.Materials and methods:The study population consisted of 651 Caucasian subjects with T2DM of more than 10 years’ duration: 276 patients with DN (cases) and 375 patients without evidence of DN (controls). Polymorphisms in ET-1 (EDN1) gene, rs5370, rs1476046, and rs3087459, were studied.Results:Genotype distributions of the studied polymorphisms showed no significant difference between cases and controls.Conclusions:We provide evidence that the rs5370, rs1476046, and rs3087459 polymorphisms ofEDN1gene are not risk factors for DN in Caucasians with T2DM.

Published: October 2017

AbstractBackground:Presence of macro- and microvascular complications in patients with diabetes mellitus (DM) is not only related to chronic hyperglycemia represented by glycated hemoglobin (HbA1c) but also to acute glycemic fluctuations (glycemic variability, GV). The association between GV and DM complications is not completely clear. Aim of our study was to evaluate GV by MAGE index in patients with type 2 DM and to verify association of MAGE index with presence of macro- and microvascular DM complications.Methods:99 patients with type 2 DM were included in the study. Every patient had done big glycemic profile, from which MAGE index was calculated. Anthropometric measurements, evaluation of HbA1c and fasting plasma glucose (FPG) and assessment for macrovascular (coronary artery disease – CAD; peripheral artery disease – PAD; cerebral stroke – CS) and microvascular (diabetic retinopathy – DR; nephropathy – DN; peripheral neuropathy – DPPN) DM complications were done.Results:Average MAGE index value was 5.15 ± 2.88 mmol/l. We found no significant differences in MAGE index values in subgroups according to presence of neither CAD, CS, PAD nor DR, DN, DPPN. MAGE index value significantly positively correlated with FPG (p < 0.01) and HbA1c (p < 0.001) and negatively with weight (p < 0.05).Conclusion:In our study we failed to show association of MAGE index with presence of macrovascular and microvascular complications in patients with type 2 DM. However, this negative result does not necessarily disprove importance of glycemic variability in pathogenesis of diabetic complications.
Clean Coal Technologies – a chance for Poland’s energy security. Decision-making using AHP with Benefits, Opportunities, Costs and Risk Analysis

Published: October 2017

AbstractThe comprehensive use of available domestic energy resources, mainly coal and lignite, is the basis for the development of Poland’s economy and energy security due to the country’s large resource base. The implementation of clean coal technologies (CCT) is a necessary condition for maintaining coal’s leading position in Poland. Coal gasification technologies are seen as potentially attractive for the Polish economy, both for the chemical sector as well as for the mining sector. Working on the commercial implementation of coal gasification technologies, which ensures the effective substitution of scarce hydrocarbon fuels, will be a challenge to Polish industrial policy and support for CCT. This paper presents an analysis of coal gasification technologies using the decision support procedures, BOCR and SWOT analyses. These procedures helped determine the ranking of technologies and the types of development strategies plausible for the analysed technological variants. Taking into consideration the conditions of the Polish economy, the highest-ranking technologies included those aimed towards the production of methanol with the geological sequestration of carbon dioxide (CCS). In the case of underground coal gasification, it was found that the technology is not yet ready for implementation on a commercial scale and investment is subject to very high risk.
Transforming Nursing Education: Fostering Student Development towards Self-Authorship
Authors: Del Prato Darlene M. 
Published: October 2017

AbstractNurse educators share a common goal: To foster student development in ways that fully prepare graduates for the challenges of contemporary practice. As patient acuity continues to escalate the responsibilities of the nurse and the nurse educator have become daunting. Contemporary practice requires a self-authored perspective that allows the nurse to appraise knowledge, weigh evidence, make autonomous decisions, and question authorities when warranted. Nurse leaders have called for transformation in nursing education through the application of evidence-based pedagogies that promote complex thinking and professional formation. This article introduces self-authorship theory and constructive-developmental pedagogy as a framework for enacting the pedagogical reform called for by nursing leaders. Drawing on the Carnegie study recommendations for nursing education reform, the article describes three constructive-developmental principles faculty can incorporate into their current practice to foster student development towards self-authorship and describes the implications of constructive-developmental pedagogy for substantive transformation in nursing education.
Language and identity construction: Evidence from the ethnic minorities of Armenia
Authors: Schulze Ilona 
Published: October 2017

AbstractThe Republic of Armenia is for the most part an ethnically homogenous country. According to the 2011 census, the share of ethnic minorities is about 1.9 percent of the population, comprising eleven registered minorities and at least two additional groups, namely the Udi and Tat refugee minorities. This article examines the different values that ethnic minorities of Armenia assign to language in the process of identity construction. Despite their cultural and religious diversity, the ethnic minorities of Armenia have a feature in common: none of the groups originates from the territory of the present-day Republic of Armenia, and in each instance immigration occurred under Tsarist or Soviet rule. Various social and historical factors related to migration condition the relevance of language for individual ethnic minorities. In some cases, these factors also influence collective self-perception in a way that is inconsistent with actual language practices and actual linguistic competence. The present article is descriptive in nature and aims at characterizing the role that language plays in identity construction by minority groups within a predominantly mono-ethnic country.

Published: October 2017

Abstract
The range of applications in which remote detection of chemical compounds is used extends from monitoring of technological processes through diagnostics of industrial installation and environmental control up to military applications. The methods and the devices used for the passive detection of selected gases are presented. The change in the signal reaching the camera caused by the presence of gas was calculated. The successful detection can be achieved if the absorption (or emission) of a gas cloud, located between object (background) and the camera, causes signal change greater or equal to noise equivalent temperature difference (NETD) of the camera.

Authors: Włodarczyk Dorota 
Published: October 2017

Abstract
This study is a continuation of the work of Professor Kazimierz Wrześniewski. It concerns the role of curiositytrait in the dynamics of changes in coping and quality of life after a heart attack. The study was attended by 222 people after a heart attack (73% men), of whom 140 participated in the three stages of the study: at the beginning and at the end of cardiac rehabilitation and a year after leaving the resort. The participants aged 24-64 years (M = 54.19; SD = 6.51). Curiosity-trait was measured by Spielberger and Wrześniewski’s STPI questionnaire. To assess coping strategies a modified version of the COPE by Carver et al., was used. The specific and general quality of life were measured by the Polish adaptations of MacNew and NHP questionnaires. The level of curiosity-trait significantly differentiated changes in the dynamics of positive reinterpretation, problem solving and resignation, but did not affect the change in quality of life within the year after a heart attack.
Experimental clues in favor of a generalized norm of reciprocity

Published: October 2017

AbstractThe norm of reciprocity (Gouldner, 1960) has only been considered and experimentally demonstrated between two individuals. However, comments from several authors invite the consideration of an expanded form of this norm. 120 passersby, randomly assigned to 3 conditions, were asked to watch a confederate’s belongings. Depending on the condition, they had either previously been given a gift or not. In addition, the gift was offered by either the confederate making the target request or by a second confederate, not initially involved. First, results show that passersby are significantly more likely to comply with the target request if they were offered a gift than if they weren’t no matter who the confederate was. Second, the confederate offering the gift gets significantly more compliance than the one not initially involved. Results are discussed in terms of self-presentation theory (Pendleton & Batson, 1979), internalization of norm (Schwartz & Howard, 1981) and positive mood induction (Isen & Al, 1978).

Published: October 2017

Abstract
According to Information-Motivation-Behavioural Skills model (IMB), accurate Information, strong Motivation and adequate Behavioural skills are prerequisites of treatment adherence. This model has been verified among chronically ills patients, usually suffering from one particular disorder. No studies report how the model fits data from a more diverse group. The aim of the study was to analyze adherence and its barriers in a group of three hundred patients suffering from various, common chronic disorders. They filled out IMB and Adherence Questionnaire. Information and Motivation correlated moderately (.35). Behavioural Skills was the strongest predictor of adherence (.24). An additional relationship was found: Information and Motivation interacted and the role of either of these dimensions vanished if the indices of the other were high enough. The relationships between IMB dimensions and adherence were confirmed in a varied clinical sample. Behavioural skills must be considered when working with non-adherent patients, as they are the strongest predictor of adherence. Other interventions may be limited to either Information or Motivation only if there is a chance of raising one of them to extreme levels. This may be useful with special cases, when increasing both is problematic.
