Screen Screen Tourism
Authors: Schulze Marion 
Published: January 2018

Abstract
In the article, I discuss new forms of mobility allowed by digital practices, i. e. digital mobilities consisting in visiting geographical places from and through a screen. This discussion is based on my online ethnographic research on international fans of South Korean television series, K-Dramas. The international fandom of K-Dramas, and in a larger sense, South Korean pop cultural products - exemplified by the success of South Korean rapper Psy’s “Gangnam Style” in 2012 -, is a continually growing global phenomenon that has been observed from the end of the 2000s on; a fandom that is mainly constituted through the Internet. However, instead of discussing already thoroughly researched “classic” participatory digital activities of television series fans, as blogging or writing fan fiction, I will focus on still overseen forms of mobility practices engendered by the watching of K-Dramas. My research shows that international fans of K-Dramas are highly mobile - but as much digitally as actually. They do not only travel physically to Korea to visit film locations. They also engage in digital mobilities to Korea through the mediation of desktop web mapping services like Google Maps and their South Korean equivalents, Daum and Naver. This screen screen tourism - as I call it -, then, differs in many ways from screen tourism how it is discussed in previous research on media. In describing and discussing these forms of digital mobility, special attention will be given to two dimensions: (1) the techniques fans use to find film locations, and (2) fans’ “ethno-mapping,” i. e. the methods they have created to map out film locations online.
‘Re-appropriating’ Facebook? Web API mashups as Collective Cultural Practice
Authors: Werning Stefan 
Published: January 2018

Abstract
In contemporary debates about socio-technical implications of software, the platform metaphor, the corresponding notions of architectures and ecosystems as well as the formatting of data to afford ‘platformization’ play a central role. This approach has certainly proven fruitful to assess the role of companies like Facebook in contemporary society. However, it characteristically overlooks the messiness of actual usage practices and those studies that do acknowledge the internal power struggles that subcutaneously shape platforms often take a top-down perspective, disregarding bottom-up processes of (re-) appropriation. To address this gap, the article outlines a method to study how users and semi-professional developers collectively frame the cultural imaginary of a platform by conducting a thoroughly comparative content analysis of mashups created using the Facebook Web API. The affordances of many individual mashups might be considered marginal; yet, the tool-assistant comparison allows for inferring common patterns of interpretation that characterize mashup creation as a mobile digital practice, which plays a key role in social media platform development.

Authors: Baltaoğlu Alp Hayriye , Darçın Sevtap 
Published: January 2018

Aim: The aim of this study was to compare ketamin(0.5mg/kg)-propofol(1mg/kg) and tramadol(1mg/kg)- propofol(1mg/kg) combination in patients undergoing uterine dilatation and curretage procedure in terms of total propofol requirement, pain scoring and recovery period of duration .Methods: 100 women under going uterine dilatation and curettage were screened retrospectively after ethical comitee approval. Patients are Dr. Faruk Sükan Doğumevi, Konya, Turkey in January-July 2014 . Baseline anesthesia was maintained with 1 mg/kg propofol, and the patients were randomly allocated to receive 0.5 mg/kg ketamine (Group 1, n=50) or 1 mg/kg tramadol (Group 2, n=50) there after. Pain scores, Aldrete scores, and hemodynamic parameters were recorded during and after the surgical procedure. A record was also maintained of any adverse events.Results: When the Aldrete scores at the end of operation, systolic pressures at basal, 0,5,10 minutes,end of op., oxygen saturation at basal,0,5,10 minutes,end of op., diastolic blood pressure at basal,0,5,10 minutes,end of op., heart rates, and visual analogue scores were compared, there was no significant difference between groups (p>0.05) Postoperative heart rate and systolic arterial pressure on beginning were significantly higher in Group 1 compared with Group 2Conclusion: Tramadol might be a better alternative drug rather than ketamine due to better hemodynamic stability and lower respiratory depression rate were seen in patents with it.
Assessment of the technical condition of welds from Al alloy grade en an 5754 using the computed tomography method

Published: January 2018

Abstract
The article presents selected results of tests conducted using the X-ray method with the application of a computed tomography device with a panel detector. The tests embraced samples of butt welds using aluminium alloy grade EN AN 5754, classified as an alloy for plastic processing with very good welding properties. The welds were executed using the TIG (Tungsten Inert Gas) method – arc welding using a non-consumable electrode in shielding gas. As a result of modernising the current welding process, it was possible to obtain better results of the welds’ technical condition assessed according to the number of welding defects.

Abstract
Sedimentological analysis of the Missão Velha Formation (Araripe Basin, northeast Brazil) is the aim of this paper through detailed facies analysis, architectural elements, depositional systems and paleocurrent data. The main facies recognized were: (i) coarse-grained conglomeratic sandstones, locally pebbly conglomerates, with abundant silicified fossil trunks and several large-to-medium trough cross-stratifications and predominantly lenticular geometry; (ii) lenticular coarse-to-medium sandstones with some granules, abundant silicified fossil wood, and large-to-medium trough cross-stratifications, cut-and fill features and mud drapes on the foresets of cross-strata, (iii) poorly sorted medium-grained sandstones with sparse pebbles and with horizontal stratification, (iv) fine to very fine silty sandstones, laminated, interlayered with (v) decimetric muddy layers with horizontal lamination and climbing-ripple cross-lamination. Nine architectural elements were recognized: CH: Channels, GB: Gravel bars and bed forms, SB: Sand bars and bedforms, SB (p): sand bedform with planar cross-stratification, OF: Overbank flow, DA: Downstream-accretion macroforms, LS: Laminated sandsheet, LA: Lateral-accretion macroforms and FF: Floodplain fines. The lithofacies types and facies associations were interpreted as having been generated by alluvial systems characterized by (i) high energy perennial braided river systems and (ii) ephemeral river systems. Aeolian sand dunes and sand sheets generated by the reworking of braided alluvial deposits can also occur. The paleocurrent measurements show a main dispersion pattern to S, SE and SW, and another to NE/E. These features imply a paleodrainage flowing into the basins of the Recôncavo-Tucano-Jatobá.
The Anti-Resonance Criterion in Selecting Pick Systems for Fully Operational Cutting Machinery Used in Mining
Authors: Cheluszka Piotr 
Published: January 2018

Abstrat
This article discusses the issue of selecting a pick system for cutting mining machinery, concerning the reduction of vibrations in the cutting system, particularly in a load-carrying structure at work. Numerical analysis was performed on a telescopic roadheader boom equipped with transverse heads. A frequency range of the boom’s free vibrations with a set structure and dynamic properties were determined based on a dynamic model. The main components excited by boom vibrations, generated through the process of cutting rock, were identified. This was closely associated with the stereometry of the cutting heads. The impact on the pick system (the number of picks and their arrangement along the side of the cutting head) was determined by the intensity of the external boom load elements, especially in resonance zones. In terms of the anti-resonance criterion, an advantageous system of cutting head picks was determined as a result of the analysis undertaken. The correct selection of the pick system was ascertained based on a computer simulation of the dynamic loads and vibrations of a roadheader telescopic boom.

Published: January 2018

AbstractAmong the ten species of the Nebria genus, present in the Romanian Carpathians, seven are the object of morphological, geographical distribution and molecular biological studies: Nebria (Eunebria) jockischi hoepfneri Dejean, 1826, Nebria (Boreonebria) heegeri Dejean, 1826, Nebria (Boreonebria) gyllenhali Schönherr, 1806, Nebria (Alpaeonebria) reichei Dejean, 1826, Nebria (Alpaeonebria) reitteri Rybinsky, 1902, Nebria (Alpaeonebria) bissenica Bielz, 1887, Nebria (Nebria) transsylvanica Germar, 1824, Nebria (Nebria) femoralis alpigrada Csiki 1905), collected from the Maramureș Mt., Rodnei Mt., Parâng Mt., Rarău Mt., Făgăraș Mt., Cozia Mt., Bucegi Mt., Retezat Mt., Muntele Mic and Semenic Mt. The morphological description exploits the body size, the elytral reflection, the colour of the appendages and the legs, the shape of the first antennary segment, its chaetotaxy and that of the submentum, the shape and size of the elytra and alae, the position of the bristles on the ventrites 4-5-6. The shape of the first antennary segment and its chaetotaxy appear as more discriminating criteria, but supposes the integrity of the bristles. The identification is sometimes malaise due to the fragility of the bristles (first antennomere, submentum). Nebria (Alpaeonebria) reichei Dejean, 1826 has a variable chaetotaxy of antenna, 1 to 3 bristles on the first antennomere. The individuals with yellow appendages and legs provided with 2 unequal length can be confused with transsylvanica. They are distinguished by the triangular shape of the aileron (S-shaped in transsylvanica). Molecular data are given for the first time on Carpathian Nebria. The mitochondrial markers (COI I, cyt b) clearly identify the species studied and confirm that alpigrada does not belong to transsylvanica. The results show an infraspecific variability of geographic and altitudinal origin in jockischi one of the most widespread species (gyllenhali, jockischi, reichei).

Published: January 2018

AbstractThe aim of this study was to evaluate the in vitro cytotoxicity of different concentrations (500-7500 μg/mL) of gentamicin - GENT (aminoglycoside antibiotic) on the selected mammalian cell line (Vero - cell line from African green monkey kidney). Analysis of the cell morphological changes was microscopically evaluated (magnification × 400). Quantification of Ca, Mg and total proteins was performed using spectrophotometry on device Rx Monza (Randox). Quantification of Na, K and Cl was performed on the automatic analyzer EasyLyte. The cell viability was assessed using the metabolic mitochondrial MTT test. Vero cells were able to survive at concentrations of 500 (89.21 %), 1000 (79.54 %) and 2000 μg/mL (34.59 %). We observed statistically significant decrease of vital cell content at concentrations of 2000, 4500, 7500 μg/mL against control group. Vero cell line slightly reacted to the presence of GENT but total proteins and mineral parameters were not significantly affected. Vero cells were highly sensitive to GENT with a significant decrease of viability at concentrations of 2000 and 4500 μg/mL (P < 0.001). Our data reveal that GENT has a significant cytotoxic and adverse effect on the cell viability.

Authors: Nastasescu Vasile , Barsan Ghita , Mocian Oana 
Published: January 2018

Abstract
The foam materials, by construction and by characteristic properties (low density, large deformations, great flexibility, Poisson ratio practically zero etc.), are widely used in many and various domains. The numerical simulation of the foam material behavior raises some difficulties, which can be impassable under certain circumstances. This paper presents some of our researching results in numerical modeling of foam materials, which can be very useful for those interested in numerical modeling of the foam materials. Numerical modeling used by the authors is based on the finite element method (FEM) and on the element-free Galerkin (EFG) method. The results are presented in a comparatively way and they also present how some usually running errors can be avoided. The conclusions and the results are considered by the authors very useful in modeling of the foam materials and in choosing of the most fitted method too.
CMPH: a multivariate phase-type aggregate loss distribution
Authors: Ren Jiandong , Zitikis Ricardas 
Published: January 2018

Abstract
We introduce a compound multivariate distribution designed for modeling insurance losses arising from different risk sources in insurance companies. The distribution is based on a discrete-time Markov Chain and generalizes the multivariate compound negative binomial distribution, which is widely used for modeling insurance losses.We derive fundamental properties of the distribution and discuss computational aspects facilitating calculations of risk measures of the aggregate loss, as well as allocations of the aggregate loss to individual types of risk sources. Explicit formulas for the joint moment generating function and the joint moments of different loss types are derived, and recursive formulas for calculating the joint distributions given. Several special cases of particular interest are analyzed. An illustrative numerical example is provided.
An Improved Family of Estimators of Finite Population Mean Using Information on an Auxiliary Variable in Sample Surveys
Authors: Singh H. P. , Yadav A. 
Published: January 2018

AbstractIn this paper we have suggested a family of estimators of the population mean using auxiliary information in sample surveys. The bias and mean squared error of the proposed class of estimators have been obtained under large sample approximation. We have derived the conditions for the parameters under which the proposed class of estimators has smaller mean squared error than the sample mean, ratio, product, regression estimator and the two parameter ratio-product-ratio estimators envisaged by Chami et al (2012). An empirical study is carried out to demonstrate the performance of the proposed class of estimators over other existing estimators.

We have made suitable recommendation to the practitioners on the basis of the empirical study.
A Cross-Sectoral Study of Value Profiles and Differences between Employees in Private and Public Sector in South East Europe
Authors: Gashi Ljuan Marko , Pozega Zeljko , Crnkovic Boris 
Published: January 2018

Abstract
This study of cultures across 6 countries (7 regions) shows that each region has its own specificity and its own unique employee value profile. Value profiles have been explored as a potential diagnostic tool on the basis of Hofstede’s value dimensions in the service of human resource development at the local level. The resulting employee value profiles are based on a representative sample of employees in the private and public sectors. Significant similarity in value profiles have been found for employees from Croatia and Serbia compared to Romania, Hungary, Slovenia and Italy, both in the public and private sector. The research results suggest the direction that managers and policymakers need to take in order to understand what employees’ values are, how they can be used, and how to address the challenges of human resource development in their region.
When a Right is a Wrong: Compensation for Acts of Necessity
Authors: Lauta Kristian Cedervall 
Published: January 2018

AbstractThe article analyses legal theory on compensation for acts of necessity. It set out to answer why a legally sanctioned act should be subject to compensation as a tort. The article accounts for present doctrines and theories. Based on this overview, the article suggest that the field presently operates from a shared set of idealised facts and that this limits the application of the prevalent theories. In order to devise a more flexible model, the article approaches the issue of compensation as inherent in the necessity decision itself. This sets out to solve the issue of compensation on a case-to-case basis under consideration of what causes the least possible interference. Accordingly, the issue of compensation must include a wide range of arguments and interests, rather than one structuring rule.
The internally layered foot in Dutch
Authors: Kager René , Martínez-Paricio Violeta 
Published: January 2018

AbstractRecent metrical studies have proposed that, under certain circumstances, a weak syllable may be adjoined to a binary foot, giving rise to a minimally recursive foot. Adding to a growing body of research from metrical stress and foot-conditioned phenomena in various languages, the goals of this paper are twofold. First, we aim at providing empirical evidence for internally layered feet based on the distribution of three foot-conditioned processes of Dutch: vowel reduction, glottal stop /ʔ/ insertion and /h/ licensing/deletion. Second, we explore a less studied theoretical and descriptive advantage of internally layered feet: their potential to predict phonological strength distinctions that go beyond the traditional weak vs. strong dichotomy. In support of this view, we will argue that all three above-mentioned foot-based processes of Dutch distinguish between two types of unstressed syllables. We will demonstrate that the metrical representation that best captures this dual patterning of unstressed syllables necessitates internally layered feet.

Published: January 2018

Abstract
Four wild type strains of A. niger were collected from soil and stream sediments representing environments with variable level of As, Sb, Al, Fe, Cd, Cu, and Zn contamination. Banská Štiavnica-Šobov (S), Pezinok-Kolársky vrch (P) and Slovinky (Sl) represent contaminated localities. Locality Gabčíkovo (G) was as a control site. The influence of toxic elements in these substrates on fungal growth, colony size, enzymatic activity, production of organic acids and their pelletization in water suspensions with montmorillonite was studied. The aim of our study was to find out how the wild type strains from (contaminated) environment will behave in different model solutions. We also wanted to add some new information in this area of study, because that there is some gap in the available knowledge.
NiCu magnetic nanoparticles: review of synthesis methods, surface functionalization approaches, and biomedical applications
Authors: Ban Irena , Stergar Janja , Maver Uroš 
Published: January 2018

Abstract
Magnetic nanoparticles (MNPs) have attracted extensive interest in recent years because of their unique magnetic, electronic, catalytical, optical, and chemical properties. Lately, research on bimetallic MNPs based on nickel and copper (NiCu MNPs) gained momentum owing to their desired properties for use in biomedicine, such as their chemical stability, biocompatibility, and highly tunable magnetic properties by means of synthesis parameter tuning. The general interest of using NiCu MNPs in biomedical applications is still low, although it is steadily increasing as can be deduced from the number of related publications in the last years. When exposed to an alternating magnetic field (AMF), superparamagnetic particles (such as NiCu MNPs) generate heat by relaxation losses. Consequently, magnetic hyperthermia in cancer treatment seems to be their most promising application in medicine, although others are emerging as well, such as their use to guide potent drugs to the targeted site or to prolong their localization at a desired site in the body. This review is the first, to the best of our knowledge, that covers the available knowledge related to the preparation of NiCu MNPs using different methods, their resulting properties, and the already developed functionalization methods and that discusses everything mentioned in relation to their possible applicability in biomedicine.

Abstract
The present study investigates the synthesis and characterization of iron oxide nanoparticles (Fe3O4-NPs) for their antibacterial potential against Bacillus cereus and Klebsiella pneumonia by modified disc diffusion and broth agar dilution methods. DLS and XRD results revealed the average size of synthesized Fe3O4-NPs as 24 nm while XPS measurement exhibited the spin-orbit peak of Fe 2p3/2 binding energy at 511 eV. Fe3O4-NPs inhibited the growth of K. pneumoniae and B. cereus in both liquid and soild agar media, and displayed 26 mm and 22 mm zone of inhibitions, respectively. MIC of Fe3O4-NPs was found to be 5 μg/mL against these strains. However, MBC for these strains was observed at 40 μg/mL concentration of Fe3O4-NPs for exhibiting 40–50% loss in viable bacterial cells and 80 μg/mL concentration of Fe3O4-NPs acted as bactericidal for causing 90–99% loss in viability. Hence, these nanoparticles can be explored for their additional antimicrobial and biomedical applications.
