BackgroundTo utilize cervical auscultation as a means of screening for risk of dysphagia, we must first determine how the signal differs between healthy subjects and subjects with swallowing disorders.MethodsIn this experiment we gathered swallowing sound and vibration data from 53 (13 with stroke, 40 without) patients referred for imaging evaluation of swallowing function with videofluoroscopy. The analysis was limited to non-aspirating swallows of liquid with either thin (< 5 cps) or viscous ($$\approx 300\,{\text{cps}}$$≈300cps) consistency. After calculating a selection of generalized time, frequency, and time frequency features for each swallow, we compared our data against our findings in a previous experiment that investigated identical features for a different group of 56 healthy subjects.ResultsWe found that nearly all of our chosen features for both vibrations and sounds showed significant differences between the healthy and disordered swallows despite the absence of aspiration. We also found only negligible differences between dysphagia as a symptom of stroke and dysphagia as a symptom of another condition.ConclusionNon-aspirating swallows from healthy controls and patients with dysphagia have distinct feature patterns. These findings should greatly help the development of the cervical auscultation field and serve as a reference for future investigations into more specialized characterization methods.

This study investigates the impact of the US monetary policy, represented through the volatility of the US government bonds rate, on the return of Dow Jones UK Islamic index. Monthly observations spans, in the period between December 2006 and June 2017, are obtained from the International Monetary Fund database. The OLS regression and granger causality analysis are used to investigate the impact. The results of the analysis show that there is significant impact of the US monetary policy on the Dow Jones UK Islamic index return.

<p>Objekatske i namjerne zavisne rečenice razvijaju se gotovo istovremeno &ndash; krajem XIV<br />i početkom XV stoljeća, vjerovatno pod utjecajem intenziviranja djelovanja pisarskih<br />kancelarija. I jedne i druge najvi&scaron;e zavise od razvoja nekada&scaron;nje optativne partikule da u veznik,<br />&scaron;to se može pratiti kroz povelje. S obzirom na to da je razvoj u toku, potrebno je razviti kriterije<br />na osnovu kojih bi se moglo pouzdanije utvrditi je li da preraslo u veznik. U radu se predlažu<br />kriteriji upotrebe glagolskog vremena u osnovnom ili prenesenom značenju, mjesta klauze u<br />rečenici, mjesta da u odnosu na glagol koji slijedi, izostavljanja rečeničnih dijelova koji se<br />ponavljaju, lica u predikatu zavisne klauze, rekcije glagola glavne klauze te složenosti predikata<br />zavisne klauze. Pored veznika da, objekatske klauze zabilježene su s veznicima kako i jere,<br />pored implicitnih i upitno-objekatskih klauza s različitim veznicima, a namjerne imaju jo&scaron; i<br />kako da i tako da, iz kojegće se razviti posljedične klauze.</p>

<p>Formiranje specifičnih okupljanja likovnih stvaraoca, najče&scaron;će imenovan terminom<br />&bdquo;Likovne kolonije", seže istorijski na sam početak dvadesetog vijeka, mapirajući regione koji<br />su naseljeni stanovni&scaron;tvom na&scaron;eg govornog područja. Osnivanje i rad ovakvih udruženja je<br />svojom brojno&scaron;ću i likovnom produkcijom u svakom smislu obogatilo dru&scaron;tveni i kulturni život<br />pojedinih regiona, a fundusi umjetničkih djela su postali nukleusi kojiće u vremenima koja<br />dolaze da obogate nacionalni kulturni sistem i postanu predmetom stručne analize i valorizacije.<br />Bosna i Hercegovina se uključila u ovaj sistem prikupljanja umjetničkih eksponata 80-tih<br />godina pro&scaron;log vijeka, i krozčetiri decenije postala bogatija za veoma veliki broj umjetnina<br />različitih kvalitativnih vrijednosti. Do sada je malo pažnje posvećivano sistematskim<br />bavljenjem i uređenjem ove oblasti, te ovaj rad ima za cilj da aktivira stručnu javnost kako bi u<br />narednim godinama taj proces bio pokrenut sa mrtve tačke.</p>

<p>Due to a large number of World Englishes spread around the world, the impact of the<br />&lsquo;core&rsquo;, long considered norm-providing, English varieties is being slowly reduced. Still, the<br />influence of the two varieties, namely Standardised British English and Standardised American<br />English, seems to be spread across the world and throughout all the varieties, in particular the<br />peripheral or, in Kachruvian terms, outer-circle varieties. However, since these two varieties<br />differ in their demographic weight and the institutional support they get, they are not equally<br />represented, with American English being greatly present through the mass media and British<br />English being dominant in foreign language teaching. The simultaneous exposure to both<br />varieties is expected to lead to the inconsistent use of the varieties in different language aspects<br />by foreign language learners, Bosnian learners of English in particular. The current paper<br />reports on the project completed by the authors with the aim of investigating whether the firstyear students at the University of Zenica tend to use both varieties intermittently through<br />different aspects, namely pronunciation, spelling, grammar and vocabulary choice or whether<br />they consistently use only one of the varieties in different language aspects, for which the results<br />obtained by descriptive and inferential statistical analysis will be employed. Furthermore, the<br />research will provide an insight into the students&rsquo; attitudes regarding the use of the<br />aforementioned varieties. The main goal of the paper is to raise awareness of English language<br />teachers and students in Bosnia and Herzegovina and to prompt them to start thinking about the<br />language they use.</p>

<p>The traditional concept of &lsquo;text&rsquo; is being replaced by &lsquo;hypertext&rsquo;, a non-linear and<br />intrinsically intertextual artifact made up of internally linked chunks of information of various<br />sorts (Caballero, 2005, p. 58). As a virtual structure, contemporary text allows for a hybrid<br />mixture of language, images, and sound. For that reason, it is certain that new technologies are<br />affecting the ways knowledge is being transmitted or constructed. In this paper, one method<br />that supports the application of a multimodal approach to text will be presented to demonstrate<br />how the four key skills may be improved: critical thinking, collaboration, communication, and<br />creativity (Galante, 2011). The four skills will be discussed in the context of vocabulary<br />acquisition from multimodal texts. The aim of the paper is to propose that these skills may be<br />significantly improved by means of vocabulary data mining from multimodal texts, and<br />integrating, in the process, the lexical syllabus into the contemporary English language course.</p>

Abstract Pulse-reverse power modes are used in galvanotechniques in order to obtain coatings with better characteristics in terms of gloss, adhesion, tracking sharp edges and uniform distribution of deposits on complex shape objects, compared with the coatings produced by constant current modes. Pulse-reverse modes also allow the use of a higher current density, and thus the production speed of electroplating cells increases. Systems for standard electroplating of copper, silver and gold are optimised by the suitable choice of duration and intensity of the pulses. It is shown that coatings with satisfactory quality can be deposited using higher current density, different modes of pulsed current in a very short period of time, without expensive and often dangerous additives in the electrolyte. Parameters of the model for certain electrochemical systems were determined by modelling and computer simulation, so the system behaviour under different circumstances becomes predictive.
