Cummingtonite-bearing volcanic rocks: first evidence in the Central Slovak Volcanic Field
Authors: Šarinová Katarína , Rybár Samuel 
Published: August 2018

Abstract
Within the framework of reinterpretation of the depositional evolution of the Komjatice depression, presence of cummingtonite in weakly lithified sediment has been detected. The sediment is formed by volcanic lithoclasts and phenocrysts with a small admixture of non-volcanic grains. The different mineral composition and various degrees of alteration of volcanic lithoclasts, together with structural features point to epiclastic origin. Therefore, the studied samples can be described as volcanic paraconglomerate and sandstone. The cummingtonite is found in rusty coloured volcanic lithoclasts and in the heavy fraction. Cummingtonite-bearing volcanic rocks have not been described so far from the Slovak Neogene volcanic fields. Therefore its presence in the studied samples represents the first indication of such volcanic rock in Slovakia. The aim of the article is to invoke interest for finding these volcanic rocks in situ.

Published: August 2018

Abstract
Oligocene successions in the North Alpine Foreland Basin (NAFB) and the Western Carpathians reflect Paratethys-wide paleogeographic changes, which also control their petroleum potential. Whereas these rocks have been studied in detail in both areas, the transition zone is still under-researched. In order to fill this gap, the Oligocene succession in the Waschberg Zone, comprising the Ottenthal Formation (NP21–23) and the overlying Thomasl Formation (NP23–24) has been studied using outcrop (Waldweg section) and borehole samples (Thomasl, Poysdorf) and a multidisciplinary approach. The Ottenthal Formation is subdivided from base to top into marls and shales (Ottenthal Mbr.), diatomaceous shales (Galgenberg Mbr.) and marlstones (Dynow Mbr.). Biogenic silica contents, determined using atomic absorption spectroscopy, reach 30 wt. % in the carbonate-free Galgenberg Member, but also in the Dynow Members, which is characterized by upward decreasing productivity of calcareous nannoplankton. Close lithological relations exist with the Oligocene succession in the NAFB, but diatoms are largely missing in the latter. Organic matter contents are surprisingly low in the Ottenthal and Thomasl formations in the Waldweg section, which therefore are poor hydrocarbon source rocks. In contrast, the Thomasl Formation, encountered in the Thomasl and Poysdorf boreholes, holds a fair to good hydrocarbon potential (~ 2.2–2.5 wt. % TOC; type III and type II kerogen) and may generate 1.0 to 1.6 tons of hydrocarbons/m2. Obviously TOC contents of borehole samples are significantly higher than in outcrop samples. Because of severe indications of weathering (e.g., presence of gypsum and jarosite), a detrimental effect of weathering on the samples from the Waldweg section cannot be excluded. Biomarker data suggest a nearshore depositional environment with changing oxygen-availability and salinity. Vitrinite reflectance measurements show that the investigated sections are thermally immature.
Adaptive Algorithm for Distribution Transformer Protection to Improve Smart Grid Stability
Authors: Patel D. D. , Chothani Nilesh , Mistry K. D. , Tailor Dhaval 
Published: August 2018

Abstract
Due to the presence of Distribution Generation (DG), power system becomes more complicated and stability of power is the main challenging task. Saturation of Current Transformer (CT) imposes great dilemma on differential relaying scheme. This manuscript presents a new differential algorithm for distribution transformer protection which adaptively set its characteristic in the event of CT saturation. The proposed scheme is capable to detect magnetizing inrush condition, high resistance internal fault and discriminate external fault with CT saturation. The validation of the proposed scheme is done by simulating a part of the power system in PSCADTM software and programming in MATLAB software. A Full Cycle Discrete Fourier Transform (FCDFT) is implemented to validate the differential protective scheme for 15 MVA, 66/11 kV distribution transformer. An adaptive concept of the differential characteristic is employed in the algorithm to maintain the stability of relay during external fault with CT saturation. Validation and authenticity of the proposed technique are carried out with various test condition generated under wide variation in system parameters. The result on 2 kVA, 230/110 V, single phase transformer shows that the proposed scheme is capable to discriminate inrush, internal and external fault also with CT saturation conditions.
Condition evaluation of steel X65 in one of the sections of “Soyuz” gas main after long-term operation
Authors: Maruschak P. , Bishchak R. , Maruschak O. , Draganovská D. , Pylypenko A. 
Published: August 2018

Abstract
The basic regularities in deformation and fracture of pipe steel X65 are revealed by testing specimens from the pipe fragment cut during the repair of the “Soyuz” gas main after 30 years of operation. It is shown that the pipe steel slightly changes its properties when the gas main is operated under the influence of working stresses and environmental factors. Structural degradation and micro-defects accumulated in the pipe wall were scattered, indicating that the material retains sufficient plasticity that allows it to resist fracture processes and the nucleation of macrocracks.
Soft computing model for analysing the effect of friction stir processing parameters on the intergranular corrosion susceptibility of aluminium alloy AA5083
Authors: Vignesh R. Vaira , Padmanaban R. , K. Chinnaraj 
Published: August 2018

Abstract
Aluminium alloy AA5083 is prone to intergranular corrosion in marine environments. In an attempt to reduce the intergranular corrosion, AA5083 was subjected to friction stir processing (FSP). The FSP experimental trials were conducted as per face-centered central composite design with three levels of variation in FSP process parameters viz. tool rotation speed (TRS), tool traverse speed (TTS) and tool shoulder diameter (SD). Intergranular corrosion susceptibility of the processed specimens was assessed by performing nitric acid mass loss test. The mass loss of the specimens was correlated with the intergranular corrosion susceptibility as per the standard ASTM G67-13. The experimental results indicate that FSP had significantly reduced the intergranular corrosion susceptibility of the AA5083 alloy. Soft computing techniques namely Artificial Neural Network, Mamdani Fuzzy system, and Sugeno Fuzzy system were used to predict the intergranular corrosion (IGC) susceptibility (mass loss) of the friction stir processed specimens. Among the developed models, Sugeno fuzzy system displayed minimum percentage error in prediction. So Sugeno fuzzy system was used to analyze the effect of friction stir processing process parameters on the IGC of the processed specimens. The results suggest that stir processing of AA5083 at a TRS of 1300 rpm, TTS of 60 mm/min and SD of 21 mm would make the alloy least susceptible to intergranular corrosion.
Enumeration of small Wilf classes avoiding 1324 and two other 4-letter patterns
Authors: Callan David , Mansour Toufik 
Published: August 2018

Abstract
Recently, it has been determined that there are 242 Wilf classes of triples of 4-letter permutation patterns by showing that there are 32 non-singleton Wilf classes. Moreover, the generating function for each triple lying in a non-singleton Wilf class has been explicitly determined. In this paper, toward the goal of enumerating avoiders for the singleton Wilf classes, we obtain the generating function for all but one of the triples containing 1324. (The exceptional triple is conjectured to be intractable.) Our methods are both combinatorial and analytic, including generating trees, recurrence relations, and decompositions by left-right maxima. Sometimes this leads to an algebraic equation for the generating function, sometimes to a functional equation or a multi-index recurrence amenable to the kernel method.

Published: August 2018

Abstract
Vertical electrical sounding, well inventory and physicochemical analysis were conducted to evaluate soil corrosivity and aquifer protective capacity of overburden units in the basement complex terrain of Ado-Ekiti, southwestern Nigeria. The topsoil is composed of slightly corrosive materials at the eastern, southern and northeastern flanks and the central portion with resistivity values ranging from 60 to 180 Ωm. Moderately corrosive/slightly corrosive materials (with resistivity values of 10 < ρ < 60 Ωm) constitute the second layer around the eastern, southern and north-eastern flanks. Pockets of areas in the northwestern, southeastern, eastern and central parts of the metropolis are practically non-corrosive with resistivity values in excess of 200 Ωm. Zones of good, moderate, weak and poor overburden protective capacity were delineated, with longitudinal conductance (S) values of 0.7 < S < 4.9, 0.2 < S < 0.69, 0.1 < S < 0.19 and S < 0.1 mhos, respectively. On a regional consideration, 23.31%, 18.80% and 57.9% of the study area is characterised by overburden materials of poor, weak and moderate protective capacity, respectively. Only 6.02% of the area indicates good overburden protective capacity.
Was beeinflusst Sportaktivität und korporales Kapital im Alter – Bildung, Einkommen oder soziale Ressourcen? Ein individuelles und institutionelles Meditationsmodell
Authors: Vollmer Johannes , Kaufmann Laura , Gieß-Stüber Petra 
Published: August 2018

Zusammenfassung
Insbesondere im Alter prägen Determinanten sozialer Ungleichheit das sportliche Handeln sowie die körperliche Verfassung und somit das korporale Kapital von Individuen. Von wesentlicher Bedeutung sind dabei die vertikalen Determinanten sozialer Ungleichheit wie kulturelles, soziales und ökonomisches Kapital. Ziel der Studie war es, direkte und indirekte Beziehungen zwischen den Kapitalarten und sportlichem Handeln zu untersuchen. Die Zusammenhänge wurden auf Basis einer Befragung von N = 320 Personen (M = 60.04 Jahre) mittels eines Mediationsmodells überprüft. Der Zusammenhang zwischen dem kulturellen und dem korporalen Kapital wurde darin vollständig durch das soziale Kapital und die Sportaktivität vermittelt. Implikationen für die Rolle des sozialen Kapitals in der Entstehung von sozialer Ungleichheit werden diskutiert.
Lietuvos Didžiosios Kunigaikštystės valdžios elito teisinės sąmonės raida XVI amžiaus viduryje (1529−1566 metais)

[article in Lithuanian; only abstract and key words in English]
Codification processes in The Grand Duchy of Lithuania during the 16th century show a rapid transformation of judicial awareness. In this case, the shift of the judicial awareness of the governing elite was caused by few conditions that distinguished this sociopolitical stratum from the estate of nobles. First, members of the governing elite were judges and consumers of the judicial system, while the rest of the nobility were just consumers; this caused a formation of a binary relation with the law. Second, the higher political and social-economical position provided advantages in a judicial process and supported a hierarchical approach to the courts of law, which could cause judicial nihilism in the perception of law and justice. Third, members of the governing elite represented different political groups, had different political, social and economic potential, had become members of this group through different means; these and other individual experiences had eclecticized the legal awareness. These conditions generated a symbiosis of archaic and new judicial ideas, which formed a qualitatively new perception of law, justice and the judicial.
Modernaus miesto plėtra: socioekologinės koncepcijos ir jų recepcija analizuojant 1870–1914 metų Vilniaus miesto struktūrą

[article in Lithuanian; abstract and key words in English]\
The aim of this article is to study the socioecological structure of Vilnius during 1870–1914 with the help of ideas derived from the analysis of modern urban development of the Chicago School of Sociology. The rapid industrialization period (mid-19th to early 20th centuries), characterized by an intensive development of modern cities in the Western world (especially in the US) and analyzed by American sociologists (R. Park, E. Burgess, R. D. McKenzie, L. Wirth), is relevant to Lithuanian historians. The cities of Lithuania that belonged to the Russian Empire during the period under investigation also experienced modernization, industrialization and urbanization processes related to it. In Vilnius, as much in the other metropolises of the Russian Empire, these processes were most intense. This article begins with the concepts of modern urban structure in the research of the representatives of the Chicago School of Sociology. We later, in the second part of the paper, present E. Burgess’s Ring-Theory of City Development, which analyzes modern urban development and is here applied to the analysis of the socioecological structure of Vilnius. The novelty of the research can be seen in the selected city ecology approach. The data in the archives and the historiography about the growing population of Vilnius, the increasing degree of specialization among the residents, the growing competition for influence and limited space, as well as residential differences, are analyzed as interrelated elements of the urban ecosystem from the perspective of E. Burgess’s theory. The study showed that between 1870 and 1914, the city’s socioecological structure clearly identifies the first (the central business district) and the second (zone of transition, area of the unqualified working class) in terms of concentrated urban zones. However, it is difficult to draw a clear line between the third (area for the working class), fourth (residential zone) and fifth (commuter zone) zones.
Migrantų diskurso formavimas istoriniais pasakojimais Lietuvos naujienų portaluose 2015 metais
Authors: Popovaitė Virginija 
Published: August 2018

[article in Lithuanian; abstract and key words in English]
In the year 2015 Europe was facing what appeared to be the worst migration crisis since World War II. Its coverage in Lithuanian media has spurred different voices to reach out for the audience: the country was facing the New Other, with whom there were no shared memories or experiences. Certain historic narratives and their motifs were invoked into discussion in order to embrace certain attitudes or actions while trying to comprehend the ongoing crisis: The Grand Duchy of Lithuania, World War II and Soviet Occupation.
The two-staged research was done in order to reveal how historical narratives were used to comprehend the possible newcomers and project outcomes of positioning migrants. 7 major news portals were used as a source of research, chosen by its importance or audience reach on national and regional levels with key words “pabėgėlis” (refugee), “migrantas” (migrant), “nelegalas” (illegal person), “bėglys” (fugitive), “atbėgėlis” (arrival). At the first stage, trending discourses and keywords were revealed, while during the 2nd the usage of historical narratives while positioning the newcomers was analysed. Data is divided according to historic moments that were used. Matrices of positioning self-other, attributing the agency and the outcome with possible suggestion of what to expect from the Others and how to comprehend them were drawn.
Results revealed that the multicultural GDL narrative was used for distancing and traumatic WWII and Soviet occupation narrations were the ones to bring migrants closer for a momentary lapse. Variety of historical passages highlights the ongoing struggle of creating the face of the New other. Narrations are done in homogenic manner instead of charging stories with ethnically diverse experiences, resulting in not giving migrants an historical time.

An Anti-Web Phishing Application for Analysing the Security of Websites
Authors: FOWDUR T.p. , KHADER R. Abdool 
Published: August 2018

Nowadays, one of the major internet security
problems being faced is ‘Web Phishing’, whereby attackers get hold of the
personal and sensitive information of the internet users. Sometimes, attackers
create fake web pages just to mislead users and give them wrong information.
With the increase of more and more sophisticated attacks like Whale Phishing,
Spear Phishing, and Ransomware among others, internet users easily fall in
attackers’ traps. Most web browsers are not able to counteract or block these
attacks and hence internet users consider the spoofed webpages to be legitimate
ones and end up giving their details like credit cards details, passwords and
usernames among others. In this paper, an application has been developed in
Java that performs several tests on a URL, on the different hyperlinks present
on the web page and on the content of the web page and provides a security
rating to the internet user. Together with the percentage security, the user is
informed if the web page is safe, doubtful or unsafe. The security ratings of
several website domains such as, .gov, .co, .edu, .info, .mu, .ac, .org, .net,
.com were also analysed. Furthermore,
tests using independent samples ANOVA and Tukey HSD were performed and they
revealed that there was a significant difference between the security ratings
of the websites.

Published: August 2018

This research work has been conducted in the field of human resource management (HRM), more specifically on firm performance. The aim of the study is to show the relationship between HRM practices and firms performance of pharmaceutical industry in Bangladesh. It is assumed that HRM practices could positively influence profitability and growth and depressingly bias employee turnover. The primary data were collected using structured questionnaire sent to employees of different departments having different job status of some pharmaceutical companies in Bangladesh. Secondary data were collected from annual reports of the selected companies for measuring and finding out their performance. The paper has tried to elucidate the role of HRM practices and to test the relationship among the variables indicating that HRD has a relationship with performance like inventory turnover, total assets turnover, net profit margin, gross profit margin etc. It is found that HRM practices enhance performance of the pharmaceutical firms in Bangladesh.
