Published: May 2015

Objective: the present study aimed to investigate whether dental wear depth perception has influence on the final quality of aesthetic direct restorations in the pre-clinical setting. Material and Methods: eighty one participants were assigned to one of three groups (n=27): G1, beginning dentistry students; G2, intermediate dentistry students; and G3, advanced dentistry students. All groups were required to prepare a tooth for facet of 1mm in depth. Subsequently, teeth were restored with opaque or translucent composite resin. Results: dental wear was different among the groups (p<0.05). G1 obtained a median of 1mm, G2 obtained a median of 0.5mm, while G3 obtained a median of 0.8mm. G3 presented more consistent accuracy in dental wear. Color values did not vary according to the dental wear depth or to the type of resin composite used in the restoration (p> 0.05). Conclusion: technical training and clinical experience contribute to the better dental wear depth perception of undergraduate dental students. No direct correlation between the dental wear depth perception and the quality of shade matching of restored artificial teeth could be performed in the pre-clinical environment.

Published: May 2015

Objective: Neodymium (Nd:YAG) and Diode LASER irradiation on adhesive systems canincrease bond strength to dentin, however, concerns about the temperature variation inside pulp chamber still remain. The aim of this study was to evaluate the intra pulp chamber temperature variation caused by irradiation with Nd:YAG or Diode LASER on different adhesive systems. Material and Methods: This study presented experimental design with two factors: LASER on two levels (Diode [D] and Nd:YAG [N]) and adhesive system on four levels (Adper™ Scotchbond™ Multi-Purpose [MP], Adper™ SingleBond 2 [SB], Clearfil™ SE Bond [CSE] and Adper™ Easy One [EO]). The quantitative response variable was the temperature variation (?t) in C. Forty bovine teeth, distributed into 8 groups (n = 5), had the buccal surface flattened up to1 mm thickness of dentin. After the application of each adhesive system, but previously to the light curing, specimens were irradiated with Nd:YAG or Diode LASER with standardized parameters. The ?t was obtained through a thermocouple inserted into pulp chamber. The values of ?t were submitted to two-way ANOVA, followed by Tukey (p < 0.05) for individual comparisons. Results: The means (± standard deviation) of ?t were: N-MP: 12.60 (± 2.51), N-SB: 10.40 (± 5.03), N-CSE: 11.80 (± 5.12) and N-EO: 10.20 (± 2.39), D-MP: 4.4 (± 1.82), D-SB: 5.20 (± 1.54), D-CSE: 4.60 (± 1.14), D-EO: 3.60 (± 1.52). Conclusion: The type of adhesive system was not significant in temperature changes generated by LASER irradiation, but Nd:YAG LASER may provide a higher potential to cause pulp damage.
Seeing the Novel, Reading the Film: Unveiling Masculinity, Englishness and Power Struggle in Arthur Conan Doyle’s The Hound of the Baskervilles
Authors: Simonova Strout Irina I. 
Published: May 2015

Abstract
Masculinity as a notion encompasses a number of identities, including psychic and social ones. During the late Victorian and early Edwardian period, masculinity as a construct underwent many changes, which affected notions of work, property ownership, sexuality, as well as power struggle with men-rivals and women. The concept of ‘manliness’ became a new moral code as well as a social imperative. Embracing this ideal was a challenging and testing experience for many men as they negotiated power, privilege and status in both the private and the public spheres of life. The Edwardian age, a transitional time in British history, became preoccupied with the consequences of the Boer Wars, gender formation, imperial policy, economic changes and many other factors. This article explores the paradigms of English masculinity and the construction of male identity as a cultural signifier in Arthur Conan Doyle’s novel The Hound of the Baskervilles and its Russian film adaptation by Igor Maslennikov. Doyle contextualizes multiple facets of masculinity from the normative to the transgressive, from the private to the public, as well as from the effeminate to the manly as his characters are affected by the anxieties and tensions of their society. After an in-depth analysis of manhood in the novel, the focus of the article shifts to Maslennikov’s adaptation and its cinematic use of the literary text, as the film interrogates masculine codes of behavior, relationships with women and the male power struggle represented in the novel. The film becomes a visual interpretation and a powerful enhancement of the narrative’s tensions and concerns.
American Art Criticism between the Cultural and the Ideological (I)
Authors: Gherasim Gabriel C. 
Published: May 2015

Abstract
Starting from the presupposition that art and art criticism in the United States of America are closely linked and that the very meanings and receptions of art works have been reflected by various writings in the field of art criticism, this first part of a comprehensive study on the topic attempts, on the one hand, to divide the historical evolution of American fine arts and art criticism into several distinct periods, and on the other, to evaluate the major directions of art criticism by considering its historical periods as being markedly ideological or cultural, as the case may be. Thus, considering the approximately 150 years of historical accomplishments of art criticism in the United States, I will argue that the starting point of American art criticism is visibly cultural, while the next two periods are characterised by ideological art criticism, noting that the ideological orientation differs in the two time frames. The fourth moment in the evolution of art criticism marks the revival of the cultural, so that, within the fifth, the postmodern art criticism could no longer grasp a clear distinction between the cultural and the ideological. The present article will focus on the first two important orientations in art criticism in the United States, 1865-1900 and 1908-1940, respectively; a future study will consider the remaining three periods, following this historicist approach of art criticism in the United States.

Abstract
The aim of the study is the evaluation of the clinical outcome and effectiveness of the arthroscopic procedures of the temporomandibular joint (TMJ) in cases resistant to the conservative therapy. The monitored group consisted of 31 patients, who underwent the arthroscopy of the TMJ and have been followed up for 3 years. The followed up patients have underwent a MRI examination of TMJ. The authors evaluate the effectiveness of the treatment in relationship to the clinical picture, radiodiagnostical imaging methods and to the arthroscopy of the TMJ.
Development and optimization of the activated charcoal suspension composition based on a mixture design approach
Authors: Ronowicz Joanna , Kupcewicz Bogumiła , Pałkowski Łukasz , Krysiński Jerzy 
Published: May 2015

Abstract
In this study, a new drug product containing activated charcoal was designed and developed. The excipient levels in the pharmaceutical formulation were optimized using a mixture design approach. The adsorption power of the activated charcoal suspension was selected as the critical quality attribute influencing the efficacy of medical treatment. Significant prognostic models (p < 0.05) were obtained to describe in detail the interrelations between excipient levels and the adsorption power of the formulation. Liquid flavour had a critical impact on the adsorption power of the suspension. Formulations containing the largest amount of liquid flavour showed the lowest adsorption power. Sorbitol was not adsorbed onto activated charcoal so strongly as liquid flavour. A slight increase in the content of carboxymethylcellulose sodium led to a marked decrease in adsorption power. The obtained mathematical models and response surface allowed selection of the optimal composition of excipients in a final drug product

Abstract
Green tea is a favorite beverage and its extracts are popular components of dietary supplements. The aim of the present in vivo study was to obtain detailed information about the effect of a standard green tea extract (Polyphenon, P), at different doses, on antioxidant enzymes and oxidative stress markers in murine blood, liver, small and large intestine. In all doses, P improved the oxidative stress status via an increased content of plasmatic SH-groups (by 21-67 %). Regarding antioxidant enzymes in tissues, the low dose of P had the best positive effect as it elevated the activity of NADPH quinone reductase in liver and small intestine, thioredoxin reductase in small intestine and hepatic superoxide dismutase. Based on these facts, consumption of green tea seems to be safe and beneficial, while consumption of dietary supplements containing high doses of catechins may disturb oxidative balance by lowering the activity of thioredoxin reductase, glutathione S-transferase, glutathione reductase and superoxide dismutase

Published: May 2015

Abstract
Heparin is widely used as an anticoagulant for the treatment and prevention of various thrombotic diseases. However, due to its high anionic charge, heterogeneity in size distribution and high polarity, its analysis is very challenging. In this paper, a novel method based on size-exclusion chromatography (SEC) for quantitative determination of intact heparin in pharmaceuticals is presented. Analyses were performed on a BioSep-SEC-S 2000 column with Larginine solution at pH 6.5 as mobile phase and UV detection at 210 nm. The proposed method was found to be selective, linear (R2 > 0.997) over the concentration range of 3.1 to 1222 μg mL-1, with a limit of detection of 1.0 μg mL-1. Intraday and inter-day precision were below 5.1 % and inaccuracy expressed as bias did not exceed 6.5 %. The reported method is simple, selective, sensitive, and requires no laborious sample preparation, which makes it appropriate for routine quantitative analysis of heparin in pharmaceuticals

Authors: Vrezec Al , Fekonja Dare , Šere Dare 
Published: May 2015

Abstract
In 2013, 73,529 birds of 161 species were ringed in Slovenia, with 114 finds from abroad, 73 finds of foreign-ringed birds and 1580 local finds. The most numerous ringed species were Blackcap Sylvia atricapilla and Barn Swallow Hirundo rustica, while among ringed nestlings Great Tits Parus major and Blue Tits Cyanistes caeruleus prevailed. The most numerous species among recoveries was the Mute Swan Cygnus olor with probably the oldest swan recorded in Slovenia so far, a 25-year-old female. The longest distance recovery concerned a Sedge Warbler Acrocephalus schoenobaenus from Norway (2,801 km). Of interest among local finds is the longest recovery distance (122 km) recorded for Ural Owl Strix uralensis in Slovenia so far. In 2013, two rare species for Slovenia were ringed, Yellow-browed Warbler Phylloscopus inornatus (2 individuals) and Siberian Rubythroat Calliope calliope, which was the first record for Slovenia. The first analysis of ringing sites in Slovenia is given as a baseline for establishing a network of Constant Effort Sites

Authors: Božič Luka 
Published: May 2015

Summary
In 2014, the International Waterbird Census (IWC) was carried out in Slovenia on 18 and 19 Jan. Waterbirds were counted on all larger rivers, along the entire Slovenian Coastland and on most of the major standing waters in the country. During the census, in which 268 observers took part, 413 sections of the rivers and coastal sea with a total length of 1395.1 km and 226 other localities (178 standing waters and 48 streams) were surveyed. Altogether, 45,346 waterbirds of 62 species were counted. This is the lowest number of waterbirds recorded after the 1997 and 1998 censuses. The greatest numbers of waterbirds were counted in the Drava count area, i.e. 20,217 individuals (44.6% of all waterbirds in Slovenia). By far the most numerous species was Mallard Anas platyrhynchos (43.0% of all waterbirds), followed by Black-headed Gull Chroicocephalus ridibundus (10.1% of all waterbirds), Coot Fulica atra (7.9% of all waterbirds), Yellow-legged Gull Larus michahellis (6.0% of all waterbirds) and Cormorant Phalacrocorax carbo (4.6% of all waterbirds). The number of 1,000 counted individuals was also surpassed by Mute Swan Cygnus olor, Pochard Aythya ferina, Tufted Duck Ay. fuligula and Teal An. crecca. Among the rarer recorded species, the Black Stork Ciconia nigra (registered for the first time during the January Waterbird Censuses; only the second winter record in Slovenia), Cattle Egret Bubulcus ibis and Flamingo Phoenicopterus roseus (both registered only for the second time during the IWC) should be given a special mention. Numbers of the following species were the highest so far recorded during the IWC: Shelduck Tadorna tadorna, Muscovy Duck Cairina moschata, Shoveler An. clypeata, Redthroated Loon Gavia stellata and Pygmy Cormorant Phalacrocorax pygmeus. Also, the total number of C and E category species/taxa was the highest to date, although still quite low with 70 individuals. Numbers of the following species were the lowest so far recorded during the IWC: Cormorant, Little Grebe Tachybaptus ruficollis and Green Sandpiper Tringa ochropus

Published: May 2015

Abstract
An autonomous mobile robot is a robot which can move and act autonomously without the help of human assistance. Navigation problem of mobile robot in unknown environment is an interesting research area. This is a problem of deducing a path for the robot from its initial position to a given goal position without collision with the obstacles. Different methods such as fuzzy logic, neural networks etc. are used to find collision free path for mobile robot. This paper examines behavior of path planning of mobile robot using three activation functions of wavelet neural network i.e. Mexican Hat, Gaussian and Morlet wavelet functions by MATLAB. The simulation result shows that WNN has faster learning speed with respect to traditional artificial neural network.

Published: May 2015

Abstract
This paper presents techniques which base on the concept of flows thinning together with the identification techniques. These methods are proposed to determine the expected number of failures to assess the efficiency of technical diagnostics of instruments. Additionally, this research focuses on the improvement of multi-machine troubleshooting systems, based on the ‘AND-OR’ graphs. Respective algorithms are presented. The majority principle uses the input information to check the correctness of the decision regarding identification of faulty machines. In this paper we base on the complete testing algorithm for elements of multi-computer complexes searching by criteria of failed element.
Equitable and semi-equitable coloring of cubic graphs and its application in batch scheduling
Authors: Furmańczyk Hanna , Kubale Marek 
Published: May 2015

Abstract
In the paper we consider the problems of equitable and semi-equitable coloring of vertices of cubic graphs. We show that in contrast to the equitable coloring, which is easy, the problem of semi-equitable coloring is NP-complete within a broad spectrum of graph parameters. This affects the complexity of batch scheduling of unit-length jobs with cubic incompatibility graph on three uniform processors to minimize the makespan.

Published: May 2015

Abstract
One of the key purposes of Business Process Model and Notation (BPMN) is to support graphical representation of the process model. However, such models have a lack of support for the graphical representation of resources, whose processes are used during simulation or execution of process instance. The paper analyzes different methods and their extensions for resource modeling. Further, this article presents a selected set of resource properties that are relevant for resource modeling. The paper proposes an approach that explains how to use the selected set of resource properties for extension of process modeling using BPMN and simulation tools. They are based on BPMN, where business process instances use resources in a concurrency manner.

Authors: Ovchinnikova Viktoria , Asnina Erika , García-Díaz Vicente 
Published: May 2015

Abstract
The software system needs to be analyzed and designed before the program code is written. A Computation Independent Model (CIM) and a Platform Independent Model/ Platform Specific Model (PIM/PSM) from Model-Driven Architecture (MDA) will be partially considered in this paper. A Topological Functioning Model (TFM) will be considered as a formal CIM, and UML sequence diagrams - as a behavioral PIM/PSM of the software system. The paper presents a short overview of the TFM and sequence diagrams with their constructs, as well as the example of transformation from the sequence diagrams to the TFM.
