Computational and Statistical Aspects of Determining Ship’s Position
Authors: Drapella Antoni , Morgaś Wacław
Published: May 2018

In its mathematical essence, the task of determining ship’s position coordinates, is to minimize appropriately defined goal function. This paper proposes to use the method of conjugate gradient for this purpose. The reason is that calculations may be performed in some seconds time because Microsoft and Apache implemented the conjugate gradient method as a tool called the Solver and embedded this tool in their widely offered and popular spreadsheets, namely Excel and the Open Office Calc, respectively. Further in this paper it is shown how to precisely assess errors of ship’s position coordinates with the Monte Carlo method that employs the Solver.

The paper presents results of the research project Social and Moral Aspects of Economic and Civic Life of Rural Youth, which was supported by the Ministry of Education, Science, Research and Sport of the Slovak Republic, through the Slovak Youth Institute under the specific scheme Support and Development of Research in the Field of Youth Policy. With the focus on the problems of contemporary life of rural youth, it emphasizes socio-economic and civic-politic dimension of its life. It maps different aspects as well as the influence of particular factors and institutions that affect behaviour and choices of young people in rural areas. The research methodology was based on qualitative approach using observation and personal semi-standardized interview method during the field survey. Interviews were conducted with 106 young people aged 18-30 from 39 rural communities localized in different parts of Slovakia in 2014. Besides introduction to the context, the authors describe methodological framework and the sampling procedure, the key research goals and questions, and basic research findings. They conclude that rural youth needs to be given certain stimulus and support in all possible areas of existence and participation, as well as tolerance and acceptance of their new ideas and thoughts.
Potential of Miscanthus × Giganteus for Heavy Metals Removing from Industrial Deposol
Authors: Dražić Gordana , Milovanović Jelena , Stefanović Slobodan , Petrić Ivana
Published: May 2018

Agro-energy crop, Miscanthus × giganteus should be produced on marginal land in order to avoid land suitable for food production. Production of electricity in thermal power plants occupies large land areas by depositing tailings from surface mines, and depositing ash and slag. During the first year of Miscanthus × giganteus growing in containers, the concentration of heavy metals: As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn and Fe was monitored in underground and aboveground plant parts. The substrate was overburden from open pit coal mine RB Kolubara and ash from TPP Nikola Tesla B. Significant differences were found between the substrate and the investigated elements, but in all cases the accumulated heavy metals almost completely remained stable in underground organs of plant. It can be concluded that biomass of Miscanthus × giganteus could be used as energy source if it is grown on a soil moderately contaminated by heavy metals.
Analysis of Selected Environmental Indicators in the Cultivation System of Energy Crops
Authors: Šoltysová Božena Š , Danilovič Martin
Published: May 2018

The changes of selected chemical parameters were observed in Gleyic Fluvisols. The field experiment was established as a twofactor experiment with four energy crops (Arundo donax L., Miscanthus × giganteus, Elymus elongatus Gaertner, Sida hermafrodita) and two variants of fertilization (nitrogen fertilization in rate 60 kg ha-1, without nitrogen fertilization). Soil samples were taken from the depth of 0 to 0.3 m at the beginning of the experiment in the autumn 2012 and at the end of reference period in the autumn 2015. Land management conversion from market crops to perennial energy crops cultivation has influenced changes of selected soil chemical parameters. The contents of soil organic carbon were affected by cultivated energy crops differently. It was found out that Arundo increased the organic carbon content and Miscanthus, Elymus and Sida decreased its content. At the same time, the same impact of the crops on content of available phosphorus and potassium and soil reaction was found. It was recorded that each cultivated crop decreased the soil reaction and available phosphorus content and increased the content of available potassium.
Determination of Production Efficiency of Crop Mixtures: the Relevance of the Agronomic Efficiency Method
Authors: Odion Ehiabhi Cyril , Ahmadu Idris Salihu , Aminu Ahmed Rufai , Luka Grace Lamba , Isah Shero Abdulazeaz , Arunah Uthman Lucky
Published: May 2018

The paper looks at estimation of the agronomic efficiency (AE) for various crop mixtures at varying levels of fertility management. To evaluate the concept, three trials using different cropping patterns and fertility rates were reviewed by calculating and comparing the relative yield and agronomic efficiency of the main crop. AE was higher in the mixtures compared to the sole crop in all the trials, and in the mixtures while efficiency between the control and the fertility levels employed were high, those between the fertility levels were not as high and increased at a reducing rate, sometimes tending to be constant. These responses gave rise to situations similar to a quadratic response and could therefore permit for optimum fertility levels for crop mixtures to be predicted. This therefore means that sustainable intensification is possible under small scale production systems as increase in efficiency was higher at lower fertilizer rates compared to the higher rates. Assessment of AE for crop mixture could also result in staggered recommended production practices, thus discouraging the excessive use of fertilizers – chemical or organic – and cut cost of production, reduce the pollution of the environment with its attendant consequences while production costs could be within reach of the small scale farmers. Small scale family farmers seeking alternative methods of soil fertility management could be encouraged to undertake the clipping/thinning management of companion leguminous crops as such measures could enhance their productivity as the estimation of AE has shown in these investigations. The practice of either clipping or thinning of the leguminous companion crop is similar or close to current production practices employed by these farmers and therefore should not be difficult to adapt and adopt.

This paper will present the development of the poka yoke systems, which were initially created and implemented just for the automotive industry, also to other domains. For some fields like medicine, constructions or software development there are already articles available on the benefits brought by poka yoke systems’ implementation. Besides these domains the article will contribute to the recognition of poka yoke systems in fields where, although error proofing systems are used, no link to the poka yoke method was made by the authors, creators and users
Regularity, positivity and asymptotic vanishing of solutions of a φ-Laplacian
Authors: Arriagada Waldo , Huentutripay Jorge
Published: May 2018

In this note we prove that solutions of a φ-Laplacian operator on the entire space ℝN are locally regular (Hölder continuous), positive and vanish at infinity. Mild restrictions are imposed on the right-hand side of the equation. For example, we assume a Lieberman-like condition but the hypothesis of differentiability is dropped. This is in striking contrast with the classical case.
Comparison Between Measurements and WRF Numerical Simulation of Global Solar Irradiation in Romania
Authors: Isvoranu Dragos , Badescu Viorel
Published: May 2018

The paper presents a comparative analysis between the surface global irradiation measured for Romania and the predicted irradiation obtained by numerical simulation. The measured data came from the Romanian National meteorological Administration. Based on a preliminary analysis that took into account several criteria among which, performance, cost, popularity and meteorological and satellite data accessibility we concluded that a combination GFS-WRF(NMM) or GFS-WRF(ARW) is most suitable for short term global solar irradiation forecasting in order to assess the performance of the photovoltaic power stations (Badescu and Dumitrescu, 2012, [1], Martin et al., 2011, [2]).
Regional Courts as Judicial Brakes?
Authors: Metcalf Katrin Nyman , Papageorgiou Ioannis F.
Published: May 2018

The article examines how regional integration courts can act as judicial brakes, at a time when “constitutional coups” – leaders staying in power past constitutional time limits or other forms of actions against the spirit if not always the letter of the constitution – are alarmingly common. The article discusses how regional courts can be used to modify or protect national rule of law and the constitutional order from the outside (i.e. from the regional integration aspect) and the extent to which this can be valid particularly to promote a uniform interpretation and application of human rights. Although this trend is visible in Europe, it is more striking, because less expected, on other continents, in particular Africa and the Americas, where the developments take place in less than perfect democratic environments. The article contains evidence from cases dealt with in the various regional courts, supporting that a system of political and judicial oversight, especially in regions with weak or fragile democratic systems, can be a useful addition to national judicial or other mechanisms of protection of rule of law and control of the executive. Action by regional courts helps defeat perceptions of majoritarian politics, which in many countries allow for the winner to take all. Under a system of regional oversight, states become aware of the limits they themselves have set and citizens become aware of their possibilities to challenge political power.

Desmid algae from three families, 17 genera were registered in the investigated habitats of the Aukštumala Telmological Reserve. A total of 56 desmid algae taxa (50 species and six varieties) were recorded. Species of the Desmidiaceae family dominated. They comprised 73% of all desmid species found. Mesotaniaceae and Closteriaceae comprised 16% and 11%, respectively. The highest diversity was discovered in the samples collected on the margins of the pools (45 species) and in the wet hollows with Sphagnum cover (35 species). Most species were found in the samples collected in August (36 species) or in March and June (25 and 28 species, respectively). The seasonal and spatial distribution of desmid algae species was observed.
Particle Swarm Optimization Algorithm with Adaptive Chaos Perturbation
Authors: Yong Dong , Chuansheng Wu , Haimin Guo
Published: May 2018

Most of the existing chaotic particle swarm optimization algorithms use logistic chaotic mapping. However, the chaotic sequence which is generated by the logistic chaotic mapping is not uniform enough. As a solution to this defect, this paper introduces the Anderson chaotic mapping to the chaotic particle swarm optimization, using it to initialize the position and velocity of the particle swarm. It self-adaptively controls the portion of particles to undergo chaos update through a change of the fitness variance. The numerical simulation results show that the convergence and global searching capability of the modified algorithm have been improved with the introduction of this mapping and it can efficiently avoid premature convergence.
Mathematical models of the Earth’s density structure and their applications in gravimetric forward modeling
Authors: Tenzer Robert
Published: May 2018

A generalized mathematical model of the Earth’s density structure is presented in this study. This model is defined based on applying the spectral expressions for a 3-D density distribution within the arbitrary volumetric mass layers. The 3-D density model is then converted into a form which describes the Earth’s density structure by means of the density-contrast interfaces between the volumetric mass layers while additional correction terms are applied to account for radial density changes. The applied numerical schemes utilize methods for a spherical harmonic analysis and synthesis of the global density structure models. The developed the Earth’s density models are then defined in terms of the spherical density and density-contrast functions. We also demonstrate how these Earth’s density models can be applied in the gravimetric forward modeling and discuss some practical aspects of representing mathematically density structures within particular components of the Earth’s interior.

Clinical Case of Aplastic Crisis Associated with Extramedullary Hematopoiesis in an Adult With Hereditary Spherocytosis and Parvovirus B19 Infection
Authors: Jercan Andreea , Gina Rusu Munteanu , Dobrea Camelia , Coriu Daniel , Tatic Aurelia
Published: May 2018

Hereditary spherocytosis is an inherited hemolytic anemia due to red cell membrane defects, characterised by chronic hemolysis with different severity degrees, splenomegaly and microspherocytosis on the peripheral blood film.

Among the possible complications in these patients are aplastic crisis and extramedullary hematopoiesis.

In this article we present the case of a 42 years old man with hereditary spherocytosis diagnosed during childhood (average haemoglobin (Hb) value of 11-12 g/dl), which presented with worsening anemia, fever, chills, bone and muscle pain. The evolution was with accentuation of anemia (Hb 4.2 g/dl), decease of reticulocyte number (Ret 0,8%) and bilirubin (indirect bilirubin 2.7 g/dl). ParvovirusB19 DNA was 100.000.000 copies/ml. A computer tomography (CT)scan was performed and showed extramedullary hematopoiesis areas situated paravertebraly in the inferior thorax and hepatosplenomegaly. The infectious episode was self-limited and improved with substitution treatment.
Actual Causes and Free Will
Authors: Sartorio Carolina
Published: May 2018

In this paper I reexamine the debate between two contrasting conceptions of free will: the classical model, which understands freedom in terms of alternative possibilities, and a more recent family of views that focus only on actual causes, and that were inspired by Frankfurt’s famous attack on the principle of alternative possibilities. I offer a novel argument in support of the actual-causes model, one that bypasses the popular debate about Frankfurt-style cases.
Diversity in the standard of living among populations in European post-comunist countries
Authors: Michalski Tomasz
Published: May 2018

The aim of this study was to present the general situation of populations of European post-communist countries 25 years after the collapse of communism in Europe. The study consists of two parts. The first one briefly discusses the processes that led to a significant diversification in the social, economic and political situations of the populations of the studied countries. In the second part the diversity of this situation is shown (using: the Legatum Prosperity Index, the Social Progress Index, and the Human Development Index). It was found that the best situations exist in the countries which quickly and effectively implemented reforms, and whether they were independent states, or parts of larger states, under communism is of secondary importance. It is symptomatic that these are countries situated in the north-western part of the area under consideration, which corresponds to the current situation in the EU-15, where the countries located in the south (the so-called PIGS) have poor economic and partly social situations than those in the north. Furthermore, it was found that the situation with the population of Russia is worse than in many countries which were previously under the occupation of the USSR or were dependent on the authorities in Moscow.
Anthropogenic causes of wetland loss and degradation in the lower Kłodnica valley (southern Poland)
Authors: Wójcicki Krzysztof J. , Woskowicz-Ślęzak Beata
Published: May 2018

Loss and degradation of wetlands is now one of the most important environmental issues on a global scale. Previous research based on analyses of cartographic materials allow for quantification of changes in wetland area in recent centuries. The results of lithological research of peat cores, reported in this publication, have established that the processes of anthropogenic loss of wetlands can be much older and in the Kłodnica valley were initiated in the first millennium BC. As a result of increased mineral sedimentation accompanying soil erosion some peatlands have been fossilized whilst the area of others has been reduced. In total, the surface area of peat-forming wetlands in the bottom of the Kłodnica valley decreased by over 60% between the time of the Lusatian Culture settlement and the Middle Ages. Post-peatland habitats are recently used for agricultural or colonized by non-peat forming vegetation. These processes have played a more important role in the degradation of peatland ecosystems than the direct human impact in historic times. Changes in hydrographic networks, land drainage and regulation of water levels in rivers and canals in the last century have contributed to further reducing the wetland areas by almost 50% compared to the 1880s. These processes, however, have mainly affected ephemeral non-peat forming wetlands.
Short-term forecasting of the chloride content in the mineral waters of the Ustroń Health Resort using SARIMA and Holt-Winters models
Authors: Dąbrowska Dominika , Sołtysiak Marek , Waligóra Jan
Published: May 2018

The Ustroń S.A. Health Resort (southern Poland) uses iodide-bromide mineral waters taken from Middle and Upper Devonian limestones and dolomites with a mineralisation range of 110-130 g/dm3 for curative purposes. Two boreholes - U-3 and U3-A drilled in the early 1970s were exploited. The aim of this paper is to estimate changes in mineral water quality of the Ustroń Health Resort by taking into consideration chloride content in the water from the U-3 borehole. The data has included the results of monthly analyses of chlorides from 2005 to 2015 during the tests carried out by the Mining Department of the Health Resort. The triple exponential smoothing (ETS) function and the Seasonal Autoregressive Integrated Moving Average (SARIMA) method of modelling time series were used for the calculations. The ability to properly forecast mineral water quality can result in a good status of the exploitation borehole and a limited number of failures in the exploitation system. Because of the good management of health resorts, it is possible to acquire more satisfied customers. The main goal of the article involves the real-time forecast accuracy, obtained results show that the proposed methods are effective for such situations. Presented methods made it possible to obtain a 24-month point and interval forecast. The results of these analyses indicate that the chloride content is forecast to be in the range of 72 to 83 g/l from 2015 to 2017. While comparing the two methods of analysis, a narrower range of forecast values and, therefore, greater accuracy were obtained for the ETS function. The good performance of the ETS model highlights its utility compared with complicated physically based numerical models.
Humour in Peer Interaction in the L2 Classroom
Authors: Leslie Carolyn
Published: May 2018

Research in the study of affect in L2 learning acknowledges that attention to the social dimension can ‘improve language teaching and learning’ and that negative emotions such as anxiety, fear, stress, anger or depression may compromise our learning potential, whereas positive emotions such as self-esteem and empathy can ease the language learning process (Arnold and Brown 1). For the majority of learners, the classroom environment should be a place which encourages interaction and minimises negative emotions such as anxiety, which could interfere with such interaction. This study seeks to describe episodes of humour during peer oral interaction which may help generate a positive social dimension amongst learners.
Industrial Policy As The European Union Competitiveness Factor On The Global Market
Authors: Bošković Gorica , Stojković Ana
Published: May 2018

The union of the most developed European countries and their heavy industry based economies after the World War II, seemed like the only answer to USA’s and Japan’s powerful economies. At the same time, it was the only chance for Europe to become competitive in the global market. That was achieved through various forms of economic communities, formed in Europe in the second half of XX century. Since the 1992. Maastricht Treaty, they are known as the European Union. European Union industrial policy had the same priorities since the very beginning – to make Europe the leader of global economy, through investments in knowledge and high-tech inovation. However, that still hasn’t happened and considering all the economical and political crisis shaking the Union lately, chances are it can hardly happen at all. Reasons are numerous and different, both inside and outside the Union. The implicit question being posed here is have the most developed world countries and their economies reached their peak and can the EU achieve further growth on the supersaturated global market? This paper investigates the role of industrial policy as one of the key factors for solution to many problems in the past as well as in the future of the EU, which would make this economic and political community of European countries much more competitive on the global market.
Genetic resources of flax (Linum usitatissimum L.) as very rich source of α-linolenic acid
Authors: Silska Grażyna
Published: May 2018

Introduction: Polish oilseed and flaxseed collection is a source of genotypes containing very high amounts of α-linolenic acid. Objective: The objective of the study is to test the seeds for the fat content and fatty acids composition in the oil pressed from the 9 tested accessions of flax (Linum usitatissimum L.). Our goal is to promote the Polish flax collection, which seeds are unique as one of the richest sources of α-linolenic acid. Methods: Assays to determine the content of fat and fatty acids composition in linseed oil were performed at the IHAR-PIB Biochemical Laboratory in Poznań. The fat content was determined by infrared analysis (calibration performed on the basis of seed sample at IHAR-PIB in Poznań) by means of a NIRS 6500 spectrophotometer with a reflection detector within the range of 400-2500 nm. The composition of fatty acids was determined by means of a method proposed by Byczyńska and Krzymański (1969), based on gas chromatography of methyl esters of fatty acids contained in linseed oil. The following varieties of flax were investigated: Tabare (INF00111), Szegedi 30 (INF00427), Olin (INF 00444), Redwood 65 (INF00523), Dufferin (INF00540), AC Mc Duff (INF00648), Alfonso Inta (INF00683), Olinette (INF00687), Royale (INF00689). Results: The content of α-linolenic acid (ALA, C18:3) in evaluated genotypes of flax ranged from 48.9 (Royale) to 59.9% (Alfonso Inta). Content of linoleic acid (LA, C18:2) in evaluated genotypes of flax ranged from 12.4 (Tabare) to 17.1% (AC Mc Duff). The content of oleic acid (OA, C18:1) of 9 accession of flax ranged from 17.1 (Alfonso Inta) to 26.7% (Royale). The content of stearic acid in evaluated genotypes of flax ranged from 2.3 (Alfonso Inta) to 5.0% (Tabare, Szegedi 30) and the content of palmitic acid ranged from 4.7 (Dufferin) to 6.0% (Olin). The content of fat ranged from 42.7 (Olin) to 52.0% (AC Mc Duff). The fatty acid ratio n-6/n-3 ranged from 0.23/1 (Tabare) to 0.32/1 (AC Mc Duff).
Trade Openness, Economic Growth and the Vicissitude of Labor-intensive Industries: The Case of China
Authors: Ying Ma , Jing Li , Guansheng Yu , Dongyang Yuan
Published: May 2018

In this paper, we use China’s 1986-2008 data to make an empirical analysis on the interrelationship between trade openness, economic growth and the structural change of labor-intensive industries by using simultaneous equation models and a VAR model. Our empirical study leads to the three conclusions. First, trade openness has accelerated economic growth, though with some negative impact on the development of labor-intensive industries; Second, economic growth has had a positive effect on trade openness, but again negatively impacted the development of labor-intensive industries. Third, the expansion of labor-intensive industries has had negative effects on both trade openness and economic growth.

Methodologically we rely on the transformation theory of industrial structure as an analytical framework to empirically study these three paradoxical outcomes. We introduce the three variables: trade openness, economic growth and the change of labor-intensive industries, as dependent as well as independent variables into our empirical models. And then we use technological progress, the share of secondary industries to GDP, total employment and investment ratio as control variables in order to test the robustness of the empirical results. In addition to explaining the factors responsible for changes in labor-intensive export industries we also provide two policy implications: First, labor-intensive industries should be scaled down to improve the efficiency of resources allocation. Second, China should timely transform its industrial structure of the export sectors from the one that is dominated by labor-intensive industries to the one that is dominated by capital (technology)-intensive industries so as to induce the export sectors to move in the direction favorable to the transformation of China’s present outward pattern of economic development.

The Interaction Between FX and Credit Risk as an Example of Intersection of Monetary and Financial Stability Policy Goals – The Case of Serbia
Authors: Jović Željko
Published: May 2018

The financial system of Serbia is highly bank-centric and euroised, which is a common specific feature of financial systems in developing countries. High level of euroisation represents an adequate environment for the development of emphasized interaction of foreign exchange and credit risks; therefore, creation of the spillover mechanism of foreign exchange risk to credit risk is immanent for euroised systems. Although maintaining the stability of the dinar exchange rate is a secondary goal of the National Bank of Serbia in relation to price and financial stability as the primary goals, in terms of existence of the aforesaid spillover mechanism, maintaining stability of the dinar exchange rate represents the area where there is an interaction between the goals of monetary policy (price stability) and those of financial stability policy (maintaining and strengthening the financial system’s stability). In order to explore whether the spillover mechanism of foreign exchange risk to credit risk exists in Serbia’s financial system, the vector autoregressive (VAR) model is applied on data from the Serbian banking sector to quantify the impact of changes in the dinar exchange rates on the rate of non-performing loans (NPLs); the sample was formed in the period of increased instability of the dinar exchange rate, from 31 January 2008 to 31 December 2010. As we have quantitatively confirmed the impact of increase in the dinar exchange rate on the increase of 90-120 days past due NPLs, we can conclude that the existence of expressed interaction between foreign exchange risk and credit risk in the Serbian financial system represents a paradigm of the regulator’s need to achieve contemporary goals of monetary and financial stability policy by maintaining relative stability of the dinar exchange rates. Depreciation of the local currency has inflationary pressure on price stability and simultaneously influences the achievement of financial stability goals through the spillover mechanism of foreign exchange risk to credit risk. In addition to taking systematic measures to reduce the level of euroisation and introduce the specific regulatory requirements, in order to protect banks and clients from the dinar exchange rate volatility, the regulator faces extremely important task of maintaining relative stability of the dinar exchange rate as the instrument to simultaneous achievement of goals of monetary and financial stability policies.
An American in King Henry's Court: Orson Welles' Chimes at Midnight
Authors: Horton Robert
Published: May 2018

Orson Welles, a boy from Kenosha, Wisconsin, was one of the most audacious Shakespearians who ever lived. He recited soliloquies as a child, wrote a book on the plays as a teenager, and at age 17 roamed across Ireland before brazenly (and successfully) presenting himself at the Abbey Theatre as a distinguished American actor. Welles also created three of the most ambitious Shakespeare films. As an American pretender, a colonial presuming to re-interpret the greatest British writer, Welles approached Shakespeare with a mix of bravado and insecurity. This paper explores how Welles' American nature informs these roles and, especially, his final Shakespeare film, Chimes at Midnight (1965). In this production, Welles plays Falstaff and is understandably identified with the role, but it could be argued that he speaks more directly through Prince Hal, whose anxiety about inheriting the throne might be reflected in the way an American Shakespearian seeks to be accepted by the British keepers of the text. The words of Hal's father, Henry IV- Uneasy lies the head that wears the crown -might apply to Welles' American-inflected depictions of kings and princes who do not entirely believe in their own royal agency. The tension between Welles‘ brashness and his fretfulness created some of the most memorable Shakespeare in the cinema.
Enter the Clowns: Adapting Shakespeare after 1642
Authors: Škrobánková Klára
Published: May 2018

This paper focuses on the genre of drolls as they were compiled in Francis Kirkman‘s collection The Wits or Sport upon Sport, published in 1672 and 1673. The anthology includes scenes from Hamlet or A Midsummer Night's Dream and draws upon characters like Falstaff and others. By description and analysis of these dramatic pieces, I would like to draw one's attention to the genre that is almost unknown to the history of English speaking drama. This article focuses on the process of rethinking Shakespeare so as not only to entertain people in the critical period of English history, but also to preserve the dramatic conventions that William Shakespeare and his contemporaries created. It also considers the changes the authors of the drolls made when adapting the parent plays of William Shakespeare.
War Games: Staging the Histories in an American Presidential Year
Authors: Bradley Kath
Published: May 2018

This paper examines the ways in which the seldom performed collaborative play, Edward III, was re-contextualised by Barbara Gaines, Artistic Director of the Shakespeare Theater of Chicago, in order to create a specifically presentist piece of theatre making a forceful political statement during the 2016 US presidential election. Edward III formed the opening section of a trilogy entitled Tug of War: Foreign Fire, which continued with Henry V, and Henry VI Part I. The second trilogy, Tug of War: Civil Strife, comprised the remaining two parts of Henry VI and Richard III. The paper will address the rationale behind the selection of these specific plays, and why it was felt unnecessary to fill the historical lacuna created by the exclusion of Richard II and Henry IV Parts I and II. In addition, it will also examine the limitations inherent in the available archival material when researching an ephemeral theatrical event, particularly one which has been edited and directed in order to address issues of immediate political concern. Selected extracts from my own review of the first of these two trilogies will seek to offer a more detailed response than is possible for journalistic reviewers and to provide sufficient background to prove of benefit for future researchers.

The present paper is focused on the figures of the Dark Lady of the sonnets and Hermia from A Midsummer Night‟s Dream as modes of writing against the Petrarchian ideal. The former is the most explicit of Shakespeare‘s suite of “dark ladies” (which includes Anne, Kate, Hero, Phoebe, Cleopatra, and Rosaline), while the latter is arguably his least individualised character, yet one that has benefitted from more public attention than most thanks to the generous circulation, continuous adaptation and re-contextualisation of the text. Two useful concepts for the discussion I propose are what Mikhail Bakhtin terms “re-accentuation” and “heteroglossia” as these texts allow different voices to dispute the place and worth of a dark-skinned woman, yet it is precisely by creating a space to voice them all that it creates a possibility to shake up the aesthetic, as well as the literary canon. The ontological status of the Dark Lady and Hermia is also of interest, so that a linguistic and stylistic analysis is carried out in order to highlight how conflicting ideologies attempt to appropriate their image, namely the hegemonic versus the inclusive understandings of what James Hughes calls the “personhood-based theory”. The revolutionary aspect brought to the table by Shakespeare is his choice for a transition from the hegemonic perspective to one which judges the two “dark ladies” on their own terms.
Shakespeare’s Weird Sisters – In Between Outlandish Womanhood and Prophesing Moirae
Authors: Avarvarei Simona Catrinel
Published: May 2018

This study intends to map the meandering expression of otherness when womanhood constructs an epiphanic encounter with time and fortune. Hereinafter, hegemonic, oppressive masculinity meets peripheral, prophesying femininity in an intricate exercise of doing and becoming Shakespeare‘s Weird Sisters, forming a complex mythological construction, whose uniqueness arises from the duality of their personae, reflection of displaced femininity, somewhat grotesque, peripheral within the realm of marginality itself. They are not only weird expressions of the Other, they are the other self of themselves, as alter ego expressions. There is a constant, minutely woven border crossing that does not only (re)define the geometry of becoming, but it also permeates gender constructions, making femaleness look androgynous and ruthless. Foretelling dreams of glory, mightiness or summoning lost humanity, these three Parcae rewrite the myth of the androgynous and its story about the quest of the Other. It is this Other that will be explored from a variety of angles that speak of masculinity, femininity, sanity, irrationality, consciousness, unconsciousness, freewill and fate.
Between Anthropocentrism and Anthropomorphism: A Corpus-Based Analysis of Animal Comparisons in Shakespeare’s Plays

The assertion of the centrality and supremacy of man, or rather, of the idea(l) of humanity, during the Renaissance period, inevitably entailed the repudiation of the animal and the beginning of the great human-animal divide. What was seen, at the time, as the re-birth of man, was also the birth of a rampant anthropocentrism which, until the recent so-called “animal turn”“ in critical and literary studies went unquestioned. Taking this into account, one would expect to find an almost exclusive focus on the human or what is/was perceived as being human in most works from that period. Yet, surprisingly, throughout Shakespeare‘s plays, one encounters a plethora of figures of animality leaping, running, crawling, flying, swimming, or advancing, as Derrida would say, “à pas de loup”“. From dogs, bears, lions, apes and foxes to birds, fish, worms and reptiles, Shakespeare the humanist paradoxically unfolds a veritable bestiary of nonhuman presences. Using corpus-based analysis that focuses on animal similes built with the preposition “like”“ and a critical angle largely informed by posthumanist theory, we take a closer look at the forms, roles and functions of both nonhuman and human animality in Shakespeare, as well as the intricate relationship between anthropocentrism and anthropomorphism.
Short-Term Forecasting of Loads and Wind Power for Latvian Power System: Accuracy and Capacity of the Developed Tools
Authors: Radziukynas V. , Klementavičius A.
Published: May 2018

The paper analyses the performance results of the recently developed short-term forecasting suit for the Latvian power system. The system load and wind power are forecasted using ANN and ARIMA models, respectively, and the forecasting accuracy is evaluated in terms of errors, mean absolute errors and mean absolute percentage errors. The investigation of influence of additional input variables on load forecasting errors is performed. The interplay of hourly loads and wind power forecasting errors is also evaluated for the Latvian power system with historical loads (the year 2011) and planned wind power capacities (the year 2023).

Using a variety of molecular techniques, it has been established that loss of pregnancy occurs in one to two thirds of all fertilized embryos in the first trimester. In about 50% of the cases, chromosomal abnormalities are the cause of early spontaneous abortion. Several histological characteristics of the placenta, such as presence of villous stromal cavitations, fetal erythrocytes, umbilical cord, fetal tissue, etc. are suggested as predictive factors for aneuploidy.

Two hundred and thirty one cases were analyzed in this prospective study, 50 cases were control artificial abortions and 181 cases were early spontaneous abortionsanalyzed in the period from May 2012 to December 2014. Standard histopathological analysis and molecular techniques based on polymerase chain reaction were used to analyze the samples.

Usingmolecular techniques, aneuploidy was detected in 53.1% of the samples. The most frequently detected aneuploidy was trisomy 16, followed by trisomy 22, 21, 14 and 18. The molecular analysis also enabled distinction of maternal and paternal origin of the alleles.

In the histopathological sample analysis, binary logistic regression analysis indicated the presence of trophoblastic proliferation (p=0.008) and the absence of fetal red blood cells (p=0.001) as independent significant factors in the prediction of aneuploidy in early spontaneous abortion.

In conclusion, our results show that clinically relevant and accurate diagnosis of early spontaneous abortion which can determine its causecan only be achieved bya controlled process of selection of the material, histo-pathological and molecular analysis, followed bya necessary correlation of these results.

Plethora of pediatric autoimmune, dermatological, neurological and atopic disease require chronic administration of steroid medication. Long-term use of corticosterioids can result in both local (atrophy of the skin, hypertrichosis, and telangiectasia) and systemic side effects (hypothalamic-pituitary-adrenal (HPA) axis disturbance, risk of infections). We report a case of 3.5-year-old boy, who developed Cushing syndrome and secondary adrenal insufficiency after corticosteroid cream maltreatment of his psoriasis. After initial hospitalization and recovery, physiological doses of hydrocortisone were used to normalize the HPA axis. In order to prevent Cushing syndrome development, adrenal insufficiencies, and secondary infections, precaution in use of steroid therapy in early childhood must be exercised.

The vast majority of experimental techniques used for the measurements of hydrogen permeability through metallic membranes whose one or both surfaces are covered with a thin Pd film is based on the assumption that a ratio of film-to-membrane thickness is small enough to cause hydrogen flow to be independent of the Pd film thickness. In an attempt to verify this assumption, we have measured the hydrogen flow through the Pd33Ni52Si15 amorphous membrane covered with Pd film of 10, 20, and 30 nm in thickness. Contrary to our expectations, we have found a dramatic decrease in hydrogen flow with the increase in Pd film thickness. Our findings are discussed in terms of potential barrier between the two different phases.

In order to properly use materials in design, a complete understanding of and information on their mechanical properties, such as yield and ultimate tensile strength must be obtained. Furthermore, as the design of automotive parts is constantly pushed toward higher limits, excessive measuring uncertainty can lead to unexpected premature failure of the component, thus requiring reliable determination of material properties with low uncertainty.

The aim of the present work was to evaluate the effect of different metrology factors, including the number of tested samples, specimens machining and surface quality, specimens input diameter, type of testing and human error on the tensile test results and measurement uncertainty when performed on 2xxx series Al alloy. Results show that the most significant contribution to measurement uncertainty comes from the number of samples tested, which can even exceed 1 %. Furthermore, moving from experimental laboratory conditions to very intense industrial environment further amplifies measurement uncertainty, where even if using automated systems human error cannot be neglected.
A Cost-effective Method for Resolution Increase of the Twostage Piecewise Linear ADC Used for Sensor Linearization
Authors: Jovanović Jelena , Denić Dragan
Published: May 2018

A cost-effective method for resolution increase of a two-stage piecewise linear analog-to-digital converter used for sensor linearization is proposed in this paper. In both conversion stages flash analog-to-digital converters are employed. Resolution increase by one bit per conversion stage is performed by introducing one additional comparator in front of each of two flash analog-to-digital converters, while the converters’ resolutions remain the same. As a result, the number of employed comparators, as well as the circuit complexity and the power consumption originating from employed comparators are for almost 50 % lower in comparison to the same parameters referring to the linearization circuit of the conventional design and of the same resolution. Since the number of employed comparators is significantly reduced according to the proposed method, special modifications of the linearization circuit are needed in order to properly adjust reference voltages of employed comparators.
