Authors: Shanker A. Shiva , Goud R. Kannaiah , Pindi Pavan Kumar 
Published: December 2018

Abstract
This study is principally aimed at the exploration of the bacterial contaminants that are prevalent in the drinking water of different reservoirs in Mahabubnagar, TS, India, along with cost-effective water treatment using palatable leaves of Mentha piperita. Water samples from three different reservoirs of Palamuru, namely, Ramanpadu reservoir (RPR), Koilsagar reservoir (KSR) and Jurala reservoir (JUR), were collected and bacteriological and chemical parameters were assessed. Colony forming units (CFU) were determined by plate culture method using different media. The bacterial diversity concomitant with the three different reservoirs was examined and compared using a molecular approach coalescing fingerprinting by denaturing gradient gel electrophoresis (DGGE). Overall, 37 16S rDNA sequences were obtained. The sequencing dominant bands validated that the major phylogenetic groups identified by DGGE belonged to Bacillus, Brevibacillus, Exiguobacterium, Gammaproteobacteria, Acinetobacter sp. and some uncultured or unidentified bacteria. At household level, incubation of potable water with pudina leaves decreased the bacterial contamination showing its anti-bacterial effect and proving it to be an easy method to impede bacterial contamination in potable water.
Prosodie en motorische spraakstoornissen: een historisch overzicht
Authors: Boutsen Frank R. , Dvorak Justin D. 
Published: December 2018

Hoewel prosodie een prominente plaats inneemt in de classificatie en differentiaaldiagnose van motorische spraakstoornissen, hebben de theoretische kaders waarin prosodie en motorische spraakstoornissen zijn ontwikkeld een volledige integratie of samenvoeging van deze domeinen beperkt. De Mayo-classificatie blijft de gouden standaard, en onderscheidt de motorische spraakstoornissen in termen van hoorbare spraakafwijkingen waaronder prosodie. Hoewel kort uitgedaagd door een prosodische classificatie van de motorische spraakstoornissen (Kent en Rosenbek, 1983), duurde het tot de theoretische vooruitgang in normale prosodie uitmondde in een door de linguïstiek onderlegde objectieve meetmethode, voordat de akoestische benadering van het meten van prosodie een echt potentieel toonde om de audio-perceptuele benadering aan te vullen voor het in kaart brengen van het prosodische landschap in motorische spraakstoornissen.

Calculating Energy Release Rate as a Function of Crack Length Using a Multiple-Step Crack Closure Technique in Tire Finite Element Models
Authors: Kelliher Dennis S. 
Published: December 2018

ABSTRACT
When performing predictive durability analyses on tires using finite element methods, it is generally recognized that energy release rate (ERR) is the best measure by which to characterize the fatigue behavior of rubber. By addressing actual cracks in a simulation geometry, ERR provides a more appropriate durability criterion than the strain energy density (SED) of geometries without cracks. If determined as a function of crack length and loading history, and augmented with material crack growth properties, ERR allows for a quantitative prediction of fatigue life. Complications arise, however, from extra steps required to implement the calculation of ERR within the analysis process. This article presents an overview and some details of a method to perform such analyses. The method involves a preprocessing step that automates the creation of a ribbon crack within an axisymmetric-geometry finite element model at a predetermined location. After inflating and expanding to three dimensions to fully load the tire against a surface, full ribbon sections of the crack are then incrementally closed through multiple solution steps, finally achieving complete closure. A postprocessing step is developed to determine ERR as a function of crack length from this enforced crack closure technique. This includes an innovative approach to calculating ERR as the crack length approaches zero.
In-Plane Flexible Ring Tire Model—Part 1: Modeling and Parameter Identification
Authors: Li Bin , Yang Xiaobo , Yang James , Zhang Yunqing , Ma Zeyu 
Published: December 2018

ABSTRACT
The tire model is essential for accurate and efficient vehicle dynamic simulation. In this article, an in-plane flexible ring tire model is proposed, in which the tire is composed of a rigid rim, a number of discretized lumped mass belt points, and numerous massless tread blocks attached on the belt. One set of tire model parameters is identified by approaching the predicted results with ADAMS® FTire virtual test results for one particular cleat test through the particle swarm method using MATLAB®. Based on the identified parameters, the tire model is further validated by comparing the predicted results with FTire for the static load-deflection tests and other cleat tests. Finally, several important aspects regarding the proposed model are discussed.
A Measuring System for Continuous Friction Monitoring on Wet Track Surfaces
Authors: Riehm Patrick , Greiner Matthias , Bückle Karl-Ludwig , Unrau Hans-Joachim , Gauterin Frank 
Published: December 2018

ABSTRACT
To improve and better understand the tire wet grip mechanism, it is essential to perform test bench measurements under wet conditions. On both public streets and the track surfaces of the internal drum test bench of the Karlsruhe Institute of Technology (KIT), a drop in the friction level of the track surface can be observed with an increasing number of wet measurements. For this purpose, a new measuring device was developed and built: the continuous friction monitoring system (CFM-System). The measuring principle is a continuously braked standard test tire, whereby a longitudinal friction coefficient is determined. To establish a suitable measuring method using the CFM-System, a basic understanding of the longitudinal behavior of this standard test tire was achieved. For this purpose, μ-slip characteristics were determined to investigate the friction behavior of this tire under different slip conditions. Furthermore, the influence of wheel load and driving speed were examined and analyzed. Based on these findings, an adequate test method was derived. The investigations presented in this article show a good relation between the results of the CFM-System and the results obtained from measurements using the standard reference test tire (SRTT). The results show that this new CFM-System is suitable for monitoring the grip level of the track surface on the internal drum test bench when performing wet grip measurements. It is assumed that the results can be directly transferred to the real road or to proving grounds because real track surfaces are used on the test bench.
Compounding and Mixing Methodology for Good Performance of EPDM in Tire Sidewalls
Authors: Hough Philip , van der Aar Niels , Qiu Zhaoyao 
Published: December 2018

ABSTRACT
Ethylene propylene diene terpolymer (EPDM), which is a terpolymer of ethylene, propylene, and a diene, is characterized by having a fully saturated polymer backbone, resulting in excellent ozone and oxidative aging resistance. By contrast, diene elastomers such as natural rubber (NR) and polybutadiene rubber (BR) have high levels of unsaturation along their main polymer backbones, increasing their susceptibility to chemical degradation by main chain scission and therefore their need for a protection system. This is generally provided by adding combinations of primary antioxidants and migrating waxes. Protective systems based on paraphenylenediamines (PPDs) are very effective and are used extensively for the protection of tire sidewalls, but because they function by preferentially reacting with ozone, their activity becomes depleted over the service life of the tire. Other potential drawbacks are that PPDs form a reaction product that discolors the surface of the sidewall, and they are considered to be potentially hazardous to human health and the environment through contamination of water systems. By contrast, it has been shown that the addition of EPDM to a conventional sidewall compound can give a permanent high level of ozone protection that is nonhazardous and non-discoloring. However, differences in polarity, solubility, and levels of unsaturation create significant challenges for achieving successful blends of EPDM in typical NR/BR sidewall compounds, leading to inferior physical and dynamic properties. This study shows that by combining best practices for compound design and mixing methodology with optimum grades of EPDM, it has been possible to produce tire sidewall compounds having full ozone protection as well as physical and dynamic properties closely matching a typical sidewall compound. Additionally, this study shows that the presence of EPDM leads to improved properties after heat aging and vulcanized compounds having reduced energy dissipation behavior, which could lead to tires having reduced rolling resistance.
Tire Lateral Vibration Considerations in Vehicle-Based Tire Testing
Authors: Albinsson Anton , Bruzelius Fredrik , Els P. Schalk , Jacobson Bengt , Bakker Egbert 
Published: December 2018

ABSTRACT
Vehicle-based tire testing can potentially make it easier to reparametrize tire models for different road surfaces. A passenger car equipped with external sensors was used to measure all input and output signals of the standard tire interface during a ramp steer maneuver at constant velocity. In these measurements, large lateral force vibrations are observed for slip angles above the lateral peak force with clear peaks in the frequency spectrum of the signal at 50 Hz and at multiples of this frequency. These vibrations can lower the average lateral force generated by the tires, and it is therefore important to understand which external factors influence these vibrations. Hence, when using tire models that do not capture these effects, the operating conditions during the testing are important for the accuracy of the tire model in a given maneuver.
An Ftire model parameterization of tires used in vehicle-based tire testing is used to investigate these vibrations. A simple suspension model is used together with the tire model to conceptually model the effects of the suspension on the vibrations. The sensitivity of these vibrations to different operating conditions is also investigated together with the influence of the testing procedure and testing equipment (i.e., vehicle and sensors) on the lateral tire force vibrations. Note that the study does not attempt to explain the root cause of these vibrations. The simulation results show that these vibrations can lower the average lateral force generated by the tire for the same operating conditions. The results imply that it is important to consider the lateral tire force vibrations when parameterizing tire models, which does not model these vibrations. Furthermore, the vehicle suspension and operating conditions will change the amplitude of these vibrations and must therefore also be considered in maneuvers in which these vibrations occur.
Experimental Measurement of In-Plane Rolling Nonpneumatic Tire Vibrations Using High-Speed Imaging

Published: December 2018

ABSTRACT
This article presents a novel experimental technique for measuring in-plane deformations and vibration modes of a rotating nonpneumatic tire subjected to obstacle impacts. The tire was mounted on a modified quarter-car test rig, which was built around one of the drums of a 500-horse power chassis dynamometer at Clemson University's International Center for Automotive Research. A series of experiments were conducted using a high-speed camera to capture the event of the rotating tire coming into contact with a cleat attached to the surface of the drum. The resulting video was processed using a two-dimensional digital image correlation algorithm to obtain in-plane radial and tangential deformation fields of the tire. The dynamic mode decomposition algorithm was implemented on the deformation fields to extract the dominant frequencies that were excited in the tire upon contact with the cleat. It was observed that the deformations and the modal frequencies estimated using this method were within a reasonable range of expected values. In general, the results indicate that the method used in this study can be a useful tool in measuring in-plane deformations of rolling tires without the need for additional sensors and wiring.

Technology Roadmaps, Innovation Journeys, and Nanoworld: A Spatio-temporal Consolidation of the EC Nanotechnology Policy
Authors: Kotlík Pavel 
Published: December 2018

Abstract
Technology roadmaps have become an essential part of the European Commission’s (EC) nanotechnology policy strategies. They represent socio-technical landscapes and evolving pathways, suggesting the underlying or otherwise supportive metaphorical patterns and narrative structures. For the same reason, however, roadmaps are problematic assemblages: they can simplify and distort reality, and filter things that don’t fit. The presented study combines cognitive linguistics with narratology to scrutinise the European Commission’s nanotechnology roadmapping as a discursive formation. It targets the systematic metaphors in approximately two-hundred news and reports on nanotechnology, compiled ad hoc from the CORDIS database (between the years 1999–2015). It is argued that the identified metaphors correspond to a discourse topology of ‘locations’, ‘events’, and their structures, especially as regards to the dilemma of ‘path dependence’, overcoming ‘knowledge gaps’, and reaching ‘nanoworld’. These are accompanied by a narrative climax of developing mature science policy model, in the arrangement of actions and roles for the European governments, science (nanotechnology), policy, and the public. The study demonstrates how systematic metaphors engage all the actors in the narrative of ‘innovation journey’ to form stabilised structures of meaning, that is, spatio-temporal consolidation of nanotechnology policy. It is imperative to continuously assess the context of such consolidation, being less overt but not necessarily less effective, in privileging some meanings, interests, and practices over the others, thereby excluding other political alternatives.

Can Social Media be a Tool for Participatory Governance in Slovak Municipalities ?
Authors: Svidroňová Mária Murray , Kaščáková Alena , Vrbičanová Veronika 
Published: December 2018

Abstract
This paper presents the first findings of research that focused on the use of social media by Slovak regional towns. Social media, namely Facebook, are considered a powerful tool for various public administration activities that do not relate only to informing citizens, but also having them participate in decision-making and municipality governance. Th e paper points out the ways of social media usage by selected municipalities. Th e research was carried out in the months of February and March 2018 using a special tool for analyzing Facebook pages called Quintly and a questionnaire survey among the employees of the municipalities. Th e results indicate that municipalities use Facebook mainly for ex-ante informing and for asking citizens to vote in various competitions that can help the local government to gain funding for some public services. Calling for participation in decision-making is very limited. Th e paper also shows a comparative perspective that can be used by municipalities but also by other local or even national governments to work further with Facebook and adopt a social media use strategy.
Prospects and challenges of multimedia approach to tourism mapping in Nigeria: a case of wildlife parks mapping
Authors: Uluocha Nna O. 
Published: December 2018

Abstract
Nigeria has a vast array of both natural and cultural tourist attractions. The country’s tourism industry, however, remains grossly underdeveloped, and the tourism resources are largely untapped. Hence, the tourism sector of the economy is yet to contribute significantly to the national Gross Domestic Product (GDP). One major factor that is responsible for the nation’s current lacklustre performance of the tourism sector is the poor state of tourism packaging and promotion, which, amongst other things is caused by the lack of appropriate tourist maps. Tourism mapping is a key component of tourism planning, development, promotion and management. For Nigeria to drastically and significantly improve the fortunes of her tourism sector, the production, circulation and use of accurate, current and comprehensive tourist maps and atlases must be vigorously pursued. To ensure sustainable tourism mapping and in line with global best practices, the country needs to adopt a Geoinformation technology-based, Internet-compatible multimedia cartographic approach. The author of this paper, therefore, examines the current state of tourism industry and tourism mapping in Nigeria. Some of the hiccups to tourism mapping in the country are identified. The implications of the present poor state of tourism mapping on tourism planning, development, promotion and management in the country are briefly considered. The author makes a strong case for the adoption of a multimedia cartographic approach to tourism mapping in Nigeria. A case of mapping wildlife parks in Nigeria is presented to demonstrate the prospects of effective multimedia tourism mapping of the country. Furthermore, the author identifies and discusses various existing resources in the country that could be harnessed for efficient and sustainable production, distribution and use of multimedia tourist maps/atlases, using Geographical Information Technologies (GIT). Some potential challenges to effective GIT-based tourism mapping in the country as well as how such challenges could be overcome, are equally discussed. Similarly, a model for Web-based, multimedia tourism mapping using GIT is presented. With clear vision, the right policy instrument, mandate, legislation, funding and coordination in place, the current challenges to effective and sustainable tourism mapping in Nigeria can easily be surmounted.
Interest and tax burden on corporations in the Czech industrial and banking sector after 2008
Authors: Sedláček Jaroslav , Němec Daniel 
Published: December 2018

Abstract
The present paper deals with the interest and tax burden of corporations in the Czech industrial and banking sector as well as with the identification of the differences between the two sectors, including the evaluation of their developmental trends in the period after the economic and financial crisis of 2008. The interest and tax burden on business entities is determined by negative cash flows that reduce the value of their assets and equity. The basis of the research is the analysis of both components of the financial burden on corporations in these sectors over the past eight years and the identification of factors influencing their capital structure and performance. According to DuPont's equation, the burden is expressed by interest and the tax reduction of corporation's earnings before interest and taxes. The amount of the financial burden depends on the macroeconomic environment where the corporations operate. Our analysis identified an asynchronous dependence between the real payments and changes in the interest and tax rates. The reduction of both rates has had a positive effect on the performance of Czech corporations and increased their capital resources. They became more attractive to foreign investors, and the return on invested capital improved. Based on the results of the analysis, we evaluated the differences in the performance of the average corporation in the banking and industrial sectors.
