Authors: Delić Aleksandra , Jovanović Boško S. , Živanović Sandra 
Published: August 2019

Abstract
We consider a class of a generalized time-fractional telegraph equations.
The existence of a weak solution of the corresponding initial-boundary value problem has been proved.
A finite difference scheme approximating the problem is proposed, and its stability is proved.
An estimate for the rate of convergence, in special discrete energetic Sobolev’s norm, is obtained.
The theoretical results are confirmed by numerical examples.

Abstract

Background
Filling of citrate tubes with appropriate amount of blood is essential for obtaining reliable results of coagulation testing. This study aimed to verify whether results of routine coagulation tests are comparable when the new Becton Dickinson Vacutainer® Citrate Plus tubes are filled at minimum or optimal volume.

Methods
The study population consisted of 133 patients (40 on oral anticoagulant therapy), who had blood collected for routine coagulation testing. Two sequential Vacutainer® Citrate Plus tubes of the same type and lot were drawn. The first tube was collected after a butterfly needle was inserted into the vein, so that the air in the tubing was aspirated into the tube before blood (minimum fill volume), whilst the second was drawn at optimal fill volume. Experiments were repeated using 2.7-mL (n = 86) and 1.8-mL (n = 47) tubes.

Results
Prothrombin time (PT) and fibrinogen values were slightly but significantly decreased in tubes with minimum than in those with optimal fill volume. The activated partial thromboplastin time (APTT) was slightly prolonged in tubes with minimum than in those with optimal fill volume, but the difference was not statistically significant. An identical trend was noted in separate analyses for the 2.7-mL and 1.8-mL tubes. Spearman’s correlations between the two fill volumes were always >0.94 and bias was always within the quality specifications.

Conclusions
Blood drawing into Vacutainer® Citrate Plus tubes at minimum fill volume does not clinically bias routine coagulation testing.
New speakers of Irish: shifting boundaries across time and space
Authors: O'Rourke Bernadette , Walsh John 
Published: August 2019

Abstract
While traditional Irish-speaking communities continue to decline, the number of second-language speakers outside of the Gaeltacht has increased. Of the more than one and half million speakers of Irish just over 66,000 now live in one of the officially designated Gaeltacht areas. While “new speakers” can be seen to play an important role in the future of the language, this role is sometimes undermined by discourses which idealise the notion of the traditional Gaeltacht speaker. Such discourses can be used to deny them “authenticity” as “real” or “legitimate” speakers, sometimes leading to struggles over language ownership. Concerns about linguistic purity are often voiced in both academic and public discourse, with the more hybridized forms of Irish developed amongst “new speakers” often criticised. This article looks at the extent to which such discourses are being internalised by new speakers of Irish and whether or not they are constructing an identity as a distinct social and linguistic group based on what it means to be an Irish speaker in the twenty first century.

Published: August 2019

Abstract
My goal in this article is to share my experiences as an academic in an institution of higher education in the United States. To a large measure, I provide insight into a world that contains multiple complexities for those who have come from a different shore. These experiences were based on my not, at first, understanding the prevailing cultural rules of the new context, with some experiences being humorous and others less so. This article presents lessons that were learned over the years that have allowed me to continue to strengthen my understanding of myself as a stranger from a different shore.
Network Neutrality Through the Lens of Network Economics
Authors: Stocker Volker , Knieps Guenter 
Published: August 2019

Abstract
Network neutrality for the Internet has been a fiercely debated topic for more than 15 years. Arguably spurred by recent regulatory actions in the US and the tremendous ecosystem evolution as characterized by the emergence and growing importance of global cloud platforms as well as the Internet of Things, the debate has recently seen a resurgence. This paper describes the origins and development of the regulatory stance towards network neutrality in the US and the EU. Against the background of the diverse evolutionary forces that shape the ecosystem, we examine network neutrality regulation through the lens of network economics. In doing so, we describe a series of challenges and misconceptions associated with current regulations and expound the requirement for a market-driven understanding of network neutrality.

Authors: Calıskan DDS, PhD Secil , Delikan DDS, MDs Ebru , Ozcan-Kucuk DDS, MDs Ayse 
Published: August 2019

Objective: Bruxism is a jaw muscle activity disorder characterized by clenching or grinding of the teeth and can be seen in both children and adults. The purpose of this study is to evaluate the parental knowledge about bruxism in children. Methods: A cross-sectional study was conducted with 265 parents whose children were attended at University of Mersin pediatric dentistry and oral and maxillofacial surgery clinics. Children’s ages varied from 6 months to 16 years old. A 20-questioned questionnaire was used to collect the data. IBM SPSS Statistics 22 for statistical analysis (SPSS IBM, Turkey) program was used for the analysis. Results: A total of 265 parents (159 were female and 106 were male) participated in the study. The majority of the parents were between the ages of 31-40 (60.8%). The rate of clenching and grinding of teeth during sleep (21.5%) was higher than the rate when they were awake (7.2%). The ratio of the parents seeking treatment for their children because of this harmful habit was very low (3.8%). The majortiy of parents (37.7%) reported that they seek help from dentists. The participants believed that bruxism was associated with dental problems (33.6%) and emotional factors (32.8%). A significant difference was found between the educational background of the parents and the ability to define bruxism. Conclusion: Parents had inadequate knowledge about bruxism in children and this was mostly related to the educational background of the parents.

Traditions and innovation in fine metalwork in the Middle Danube region in the second half of the 5th and the early 6th centuries A.D. Once more on the 'Szarvas' brooch group: new finds, new hypotheses
Authors: Tóth Ágnes B. 
Published: August 2019

AbstractThe aim of this paper is to examine a group of brooches whose numbers have been increasing in recent years to determine their origins, their relationship to each other and their role in the fine metalwork, goldsmith practice of the period. These brooches and pairs of brooches were found in ten sites scattered across a large geographic area (Szarvas, La-Rue-Saint-Pierre, Bernhardsthal, Uppåkra, Narona, Hemmingen, 'Italy', Collegno, Domoszló, Nagyvárad). The artefacts share common features that can aid in determining the areas of production for objects within the group. We can confidently date them to the second half of the 5thand the early 6thcenturies A.D. and examine their role in the development of the so-called Thuringian-type brooches. Furthermore, they allow us to investigate changes in female attire and shed light on the relationships between the Middle Danube region and Southern Sweden (Skåne).

Microseismic Focal Mechanisms and Implications for Changes in Stress during the 2014 Newberry EGS Stimulation
Authors: Aguiar Ana C. , Myers Stephen C. 
Published: August 2019

Abstract
We adapt the relative polarity method from Shelly et al. (2016) to compute focal mechanisms for microearthquakes associated with the 2014 hydroshearing stimulation at the Newberry volcano geothermal site. We focus the analysis on events relocated by Aguiar and Myers (2018), who report that six event clusters predominantly comprise the 2014 sequence. Data quality allows focal mechanism analysis for four of the six event clusters. We use Hardebeck and Shearer (2002, 2003; hereafter HASH) to compute focal mechanisms based on first‐motion polarities and S/P amplitude ratios. We manually determine P‐ and S‐wave polarities for a well‐recorded reference event in each cluster, then use waveform cross correlation to determine whether recordings of other events in the cluster are the same or reversed polarity at each network station. Most waveform polarities are consistent with the affiliated reference event, indicating similar focal mechanisms within each cluster. The deeper clusters are east–west‐striking normal faults, whereas the shallower clusters, close to the top of the open‐hole section of the borehole, are strike slip with east–west motion. Regional studies and prestimulation borehole breakouts find the maximum stress direction is vertical and maximum horizontal stress is approximately north–south. Fault geometry and focal mechanisms of microseismicity during the stimulation suggest that increased pressure from fluid injection predominantly caused changes in horizontal stress, consistent with predictions from numerical studies of stress change caused by fluid injection. At shallow depths, where previous studies suggest the difference between vertical and horizontal stress is lowest, injection appears to have rotated the direction of maximum stress from vertical to horizontal, resulting in strike‐slip motion. At greater depth, vertical stress continued to be the dominant direction during the stimulation, but fault orientation indicates either reactivation of pre‐existing fractures or rotation of the direction of maximum horizontal stress from approximately north–south to east–west.

Background: At present, there are no methods for intraoperative monitoring of the interventricular septum (IVS) thickness in a stopped and empty heart. This might be an obvious reason for unsatisfactory results after a number of septal myectomies.Aim: To provide an experimental background for the method to control the IVS thickness (that we had proposed) during septal myectomy.Materials and methods: The proposed technique is based on the transillumination method. The experimental models were cadaveric porcine hearts, as well as fragments of the human myocardium removed during septal myectomies. The thickness of the translucent myocardium was estimated depending on the local illumination value at the entrance to the myocardium and the external illumination of the surgical field. We compared the results of 67 septal myectomies performed in the clinic of the Almazov National Medical Research Centre with the results of 35 similar experimental procedures with cadaveric porcine hearts using the proposed way of measurement.Results: A graph of the illumination at the entrance to the myocardium against the thickness of the translucent myocardium was constructed. After conventionally performed septal myectomies the median variation of the myocardial thickness was 4 [3; 6] mm. In the experiment using the proposed control method, the median variation was 1 [1; 2] mm, i.e. significantly less than with the conventional approach (p = 3 x 10-10).Conclusion: The method to control the IVS thickness when performing septal myectomy makes it possible to achieve the required myocardial thickness the resection area with much greater accuracy than with the conventional one.

Transoral Robotic Surgery Versus Chemoradiation Treatment in Oropharyngeal Cancer: Case-matched Comparison of Survival and Swallowing Outcomes
Authors: Sommerfeld Connor , Jeffery Caroline , Clark Jessica M , O'Connell Daniel A , Harris Jeffrey , Seikaly Hadi , Biron Vincent 
Published: August 2019

Abstract
Background

As the incidence of HPV/p16-positve oropharyngeal squamous cell carcinoma (OPSCC) continues to rise, a large population of survivors with treatment related morbidity is emerging. Transoral robotic surgery (TORS) is an excellent surgical option for p16-positive OPSCC but data comparing both survival and swallowing outcomes of this treatment versus radiotherapy/chemoradiotherapy (RT/CRT) remains limited.

Methods

Data was prospectively collected (05/2014 - 02/2019) in a tertiary care referral center from OPSCC patients treated with curative intent by TORS (+/-post-operative RT/CRT) or RT/CRT. Surgical and non-surgical treatment groups were case-matched for smoking status, T-stage, and N-stage based on AJCC 8th edition staging. Patients who were treated with curative intent by TORS (+/-post-operative RT/CRT) or RT/CRT for OPSCC were included. Overall survival, recurrence free survival, aspiration free survival and gastrostomy tube outcomes were compared using univariate and multivariate statistical analyses.

Results

A total of 82 patients treated with TORS were case-matched with 61 patients who received RT/CRT. TORS patients demonstrated a significantly (p=0.02) higher overall survival (OS) at 3 years (OS=93.2%) compared to RT/CRT patients (OS=78.9%). No statistically significant difference was seen in recurrence free survival when comparing the two groups. TORS patients demonstrated an aspiration free survival (AFS) of 64.7% compared to 26.1% in RT/CRT patients (p=0.02 Log-Rank, 0.018 Breslow). TORS patients also had significantly (p < 0.01) lower gastrostomy tube placement (13.4%) compared to RT/CRT (22.9%) at any point during treatment.

Conclusion

Patients undergoing treatment by TORS may have comparable survival and improved swallowing outcomes when compared to those undergoing RT/CRT for HPV-OPSCC.
The Short Run Effects of Health Aid in Low Income Countries:Evidence from Panel Data Analysis
Authors: Negeri Keneni Gutema 
Published: August 2019

Abstract
Background The effect of health targeted aid in developing countries is debatable. This paper examines the short run effect of health aid on health status in low income countries of the world. Method The study estimates the short run effect of health aid on health status in low income countries. Infant mortality rate was used as a proxy for health status and a panel data was constructed from 34 countries for the period between 2000 and 2017. For the estimation, first difference GMM and System GMM were employed. Results The estimation results confirm the argument that health aid has a beneficial and statistically significant short run effect on the health status of low income countries: doubling health aid saves the lives of 20 infants per 10,000 live births. Conclusion From the findings of this paper it can be concluded that health aid could be one of the best tools with which the broader health status gap currently observed between high income and low income groups, could be eliminated and hence the target of Universal Health Coverage is met. However, recipient countries need to find ways of promoting domestic factors that have favorable impact on health sector as they cannot persistently relay up on external resources.
Use of floating seals to exclude oxygen penetration in non-aerated selectors
Authors: Jobbágy A. , Weinpel T. , Bakos V. , Vánkos Zs. 
Published: August 2019

Abstract
It is widely assumed that non-aerated selectors are very efficient in nutrient removal, and especially anaerobic basins may largely contribute to good sludge settleability as well. However, based on results measured in full-scale, this paper draws attention to the fact that with decreasing availability of readily biodegradable carbon source (rbCOD) being experienced worldwide, oxygen penetration into non-aerated basins through the uncovered surface may no longer be considered negligible. When the oxygen mass transfer is significant compared to the available influent rbCOD, non-aerated selectors should be regarded as basins with low dissolved oxygen (low DO) concentrations that may underperform with respect to nutrient removal and favor the growth of filaments, especially during low-loaded conditions. In order to fully exclude oxygen penetration, floating seals have been developed and applied at the North-Budapest Wastewater Treatment Plant in Hungary. Comparative full-scale studies showed prevention of significant amounts of influent rbCOD loss (up to 60 mg/L) through the application of this new technology. This amount of saved, non-oxidised but fermented carbon source could be accordingly used for enhancing biological P-removal. Due to the elimination of microaerophilic conditions, the undesirable growth of filamentous bacteria could also be avoided, leading to significantly better activated sludge settling.
POLAND’S MEMBERSHIP IN THE MONETARY UNION IN LIGHT OF SELECTED LEGAL AND INSTITUTIONAL ASPECTS OF THE CRISIS IN THE EURO AREA
Authors: Hoffmann Tomasz 
Published: August 2019

The principal research goal of this paper is to indicate and characterise the legal and institutional instruments that have been implemented in order to mitigate the consequences of the crisis. The main cause of the crisis in the euro area was the all too liberal approach to financial speculation coupled with a loss of control over financial markets on the part of the authorities of particular Member States. The crisis that had initially engulfed the United States spread relatively quickly across Western Europe, affecting the Members States of the EU. The crisis was felt most deeply in countries such as Portugal, Spain, Ireland, Italy, and Greece, whereas the many negative consequences of the excessive debt incurred by these countries affected the entire EU. The hitherto applied fiscal and legal means of counteracting the consequences of the crisis, although appropriate, have failed to yield the anticipated results, leading to mounting political tension between the major contributors amongst EU Member States.

Published: August 2019

Introduction: Periapical cysts are the most frequent odontogenic cystic lesions, commonly asymptomatic and discovered in routine dental examinations. The treatment may vary according to the size of the cyst. Objective: The objective of this study is to report the diagnosis and treatment of a large periapical inflammatory cyst in the maxilla. Case report: Patient A.B., 38 years old, male with major complaint of pain in the left maxilla region, facial asymmetrywith increased volume in the zygomatic bone region. After the intrabuccal and radiographic examinations, a lesion with a dimension of approximately 6.5 cm was observed, extending throughout the of the upper left side, with well-defined extension. It was performed the extraction of the affected teeth, collection of the biological material for histopathological analysis and installation of a drain for decompression maintained in the buccal cavity for 6 months with periodic irrigations with saline solution. After regression of the lesion, enucleation and curettage were performed. After 36 months following-up it is possible to observe absence of signs and symptoms of lesion recurrence, with good healing and bone neoformation. Conclusion: Decompression followed by enucleation forthe treatment of periapical inflammatory cyst should be considered as a treatment option because it minimizes damage to adjacent anatomical structures.
