Open porosity of cement pastes and their gas permeability
Authors: Tracz T. 
Published: December 2016

AbstractThis paper presents the results of extensive research work on the open porosity and gas permeability of cement pastes. Tests were conducted on cement pastes with different water/cement ratios and types of cement. The three most popular cements in Poland from the CEM I, CEM II and CEM III groups were tested after the pastes had been cured for 90 days in laboratory conditions. The scope of experiments included the assessment of open porosity determined using three different methods: comparing the bulk and specific densities, mercury intrusion porosimetry and saturating the material with water. In addition, this article contains an analysis of the porosity characteristics based on the distributions produced by porosimetry examinations. Gas permeability was determined using the modified RILEM-Cembureau laboratory method. The results of the completed test allowed a quantitative determination to be made of the impact of water-cement ratio and type of cement used on open porosity assessed by various methods, and the influence of these parameters on the gas permeability of the paste. The quantitative changes in the content of capillary pores and meso-pores in the cement pastes analysed are also presented.
Cayley-Hamilton theorem for Drazin inverse matrix and standard inverse matrices
Authors: Kaczorek T. 
Published: December 2016

Abstract
The classical Cayley-Hamilton theorem is extended to Drazin inverse matrices and to standard inverse matrices. It is shown that knowing the characteristic polynomial of the singular matrix or nonsingular matrix, it is possible to write the analog Cayley-Hamilton equations for Drazin inverse matrix and for standard inverse matrices.
Evaluation of accuracy of digital map data via multiple comparisons
Authors: Doskocz A. , Rejchel W. 
Published: December 2016

Abstract
Digital map data sets (or geo-databases) are an important part of the spatial data infrastructure (SDI) of the European Community. Different methods of producing large-scale map data are described in the paper, and the aim is to compare the accuracy of these methods. Our analysis is based on statistical tools belonging to the multiple comparisons theory. The first method is the well-known analysis of variance (ANOVA), and the second one is the rank-based method. The latter approach, which is rarely used in geodetic research, allows us to determine the order of the considered methods with respect to the positional accuracy of digital map data that they produce. Using this approach, one can identify the least accurate set of map data or a fragment of a map that should be updated by a new direct survey. The rank-based methods can also be rather easily applied to other technical (engineering) disciplines, e.g. geodesy and cartography.
Application of transverse functions to control differentially driven wheeled robots using velocity fields
Authors: Pazderski D. 
Published: December 2016

Abstract
This paper deals with control of a nonholonomic unicycle-like robot in a cluttered environment with static obstacles. The proposed solution is based on a combination of a universal motion controller taking advantage of transverse functions with a navigation velocity field determining a path in a free task space. The motion controller is used to imitate an omnidirectional planar kinematics such that nonholonomic constraints become hidden for a navigation layer. Then it is possible to generate vector fields which govern motion of the omnidirectional frame. The controller using the transverse function is discussed in depth. In particular, a possible parametrization of this function is considered and analysis of an augmented dynamics is provided for different motion patterns. Next, construction of obstacles and potential design for star-like shapes are presented. The navigation algorithm is verified experimentally and the results are discussed.
Inversion of selected structures of block matrices of chosen mechatronic systems
Authors: Trawiński T. , Kochan A. , Kielan P. , Kurzyk D. 
Published: December 2016

AbstractThis paper describes how to calculate the number of algebraic operations necessary to implement block matrix inversion that occurs, among others, in mathematical models of modern positioning systems of mass storage devices. The inversion method of block matrices is presented as well. The presented form of general formulas describing the calculation complexity of inverted form of block matrix were prepared for three different cases of division into internal blocks. The obtained results are compared with a standard Gaussian method and the “inv” method used in Matlab. The proposed method for matrix inversion is much more effective in comparison in standard Matlab matrix inversion “inv” function (almost two times faster) and is much less numerically complex than standard Gauss method.
Investigation of HID-lamp light emission differences for different power supply methods
Authors: Tomczuk K. , Mazurek P. , Hemka L. , Kasprowicz A. , Błażejczyk T. 
Published: December 2016

Abstract
This paper presents investigation of methods for reducing light pulsation and plasma temperature inside a high intensity discharge (HID) lamp arc tube. Differences found in light emission of an arc tube plasma channel under different power supply methods are presented and discussed in this work. The novelty of the paper lies in systematical investigation of different power converter supply methods and demonstrating that it has a significant influence on plasma temperature in an arc tube. The tested lamp was powered by electronic ballasts controlled by different algorithms, which forced their current waveform. To compare the results, the authors performed measurements on a discharge lamp powered by a standard electromagnetic ballast. The investigation of plasma parameters is based on the optical spectroscopy method. It was shown that by using the appropriate current shape of a high switching frequency supply converter, the plasma temperature of an HID lamp can be reduced almost by half.
Distributed active demand response system for peak power reduction through load shifting
Authors: Benysek G. , Jarnut M. , Werminski SZ. , Bojarski J. 
Published: December 2016

Abstract
The large variability in power consumption in electrical power systems (EPS) influences not only growth balance losses and technical losses, but also in some cases reduces energy security. Delayed restoration of power generation, combined with unpredictable weather events leading to the loss of generating power can lead to a situation in which to save the stability of the power system there must be introduced in the system a load power limit or even disconnection of end-user in a given area, which will significantly reduce the comfort of use of energy. This situation can be prevented through either the building of new intervention power units or the aggregated use of new energy technologies, such as distributed network resources (DER), which are part of an intelligent Smart Grid network. Such resources bring together virtual power plants (VPP) and demand side management (DSM). The article presents an alternative decentralized active demand response (DADR) system, that by acting on selected groups of loads reduces peak loads with minimized loss of comfort of energy in use for the end-user. The system operates without any communication. The effectiveness of the proposed solution has been confirmed, outlined in test results obtained by the authors from a developed analytical model, which also contains stochastic algorithms to decrease the negative impact of such DSM systems on the power system (power overshoot and oscillation).
Surface modification of ZrO2-10 wt. % CaO plasma sprayed coating
Authors: Iwaszko J. , Kudła K. 
Published: December 2016

Abstract
Oxide ZrO2-CaO plasma-sprayed coatings were remelted using the modified gas tungsten arc welding (GTAW) method. The original two-burner set, generating a free independent arc, was used in the treatment. The samples were subjected to structural examination using light and scanning electron microscopes, and energy-dispersive X-ray microanalysis (EDX). A substantial heterogeneity of the plasma-sprayed coatings was found, observable with a laminar structure, significant porosity, and step change in the concentration of the elements. Significant changes in the structure were found after the remelting treatment. Both microscopic and EDX investigations showed that the treatment leads to a reduction in the heterogeneity of the chemical composition of the coating material and to a loss of structural characteristics typical for plasma-sprayed coatings.
Bridging Hmong/Miao, Extending Miaojiang: Divided Space, Translocal Contacts, and the Imagination of Hmongland
Authors: Zhang Weidong , 东 张伟 
Published: December 2016

Abstract
Over the past several decades, the Hmong communities scattered around the world and their co-ethnic Miao ethnic group in China came into close contact. This paper explores the nature and dynamics of this encounter as well as the connections and ties that have been rediscovered and reestablished between the Hmong in diaspora and the Miao in China, two groups long separated by time and distance, and the impact and implications this entails. Based on three-month fieldwork in the Hmong/Miao communities across Southwest China and Southeast Asia, this paper examines the ever increasing movement of people and materials, as well as symbolic flows on the one hand, and connections and linkages between different localities on the other hand. It discusses how this new fast-changing development contributes to a new translocal imagination of Hmong community, re-territorialization of a new continuous Hmong space, a Hmongland encompassing Southwest provinces of China and northern part of Southeast Asian countries, and what it means to the Hmong/Miao people in the region. It further discusses how the emerging translocal imagination of the Hmong/Miao community will produce unique translocal subjects and how it interacts with the nation-states they belong to.
The Competition for Gifts: The Social Mechanism of the Revival of Popular Religion – An Ethnographic Study of Fu Village in Eastern Zhejiang
Authors: Song Yuan , Jia Ge , 松 袁 , 佳 葛 
Published: December 2016

AbstractThis article uses the “gift paradigm” to understand the social mechanism of the revival of popular religion in developed rural areas. In eastern Zhejiang, peasants burn “Buddha paper [money]” (fozhi)Althoughfoliterally means “Buddha,” in the local dialect of Zhejiang it is better understood as a generic term for “deity,” including Buddha. – Trans.as a gift when making vows and praying to deities. They consider the fulfillment of their prayers repayment by the deities. The reciprocity between human and deity forms a chain of return gifts, with the household as the unit and the year as the interval, which is permeated with affection and morality. In recent years the economic growth of rural economies in eastern Zhejiang has synchronized with social diversification. Village upper classes, which are the most sensitive to risk, have become the main bodies of faith consumption, purchasing masses of Buddha paper or even hiring people to chant scriptures. Their potlatch-style gift display has led to imitation by other classes. Different classes have gone into intense competition over the degree of intimacy with the deities. The competition for symbolic capital is the driving force of the constant expansion of popular religious activities in this area. The rapid growth of Buddha paper consumption has made it impossible for household providers who offer ritual services to meet the demand. They therefore convene older people to form scripture-recitation groups to enlarge their supplies. The use of scripture chanting (nianfo, literally “reciting Buddhist texts”) results in a redistribution of superfluous wealth in villages to their middle and lower classes, via acquaintance networks. Everyday practices of eastern Zhejiang villagers show that popular religious activities in their society have a self-contained logic that has brought about an expansion in the competition for intimacy with deities. Society, on the other hand, has achieved integration in the circle of gift exchange between human and deity. Although the holistic view of the “gift paradigm” is the key to unlocking this popular religion revival, both the “power paradigm” and the “society paradigm” of gift exchange are indispensable in understanding the nature of the relationship in local popular religion.

Authors: Gerhant Aneta , Olajossy Marcin , Kalińska Agata , Miernicka Agata 
Published: December 2016

Abstract
Aim: The objective was to analyze the case of postpartum depression complicated with extended suicide attempt.
Method: The analysis of clinical case and medical history.
Results: In 25-year-old patient, two weeks after childbirth, postpartum depression episode occurred. In the further course of illness psychotic symptoms (delusions, mood disorders), suicidal and infanticide thoughts emerged. Four weeks after childbirth, the patient killed her baby and took an unsuccessful suicidal attempt. Based on medical records, several risk factors of postpartum depression were identified: 1. obstetric and child-related risk factors: Caesarean section, premature birth, obstetric complications during pregnancy, infant’s difficult temper, difficulties related to breastfeeding; 2. psychological risk factors: baby blues, high anxiety level during pregnancy, high level of stress related to child care.
Conclusions: Psychoeducation of women during pregnancy, including their families, is an extremely crucial element of postpartum depression prevention. It is also necessary to raise awareness among healthcare professionals who have frequent contact with mothers after childbirth: midwives, gynaecologists and paediatricians.
Risk behaviors at late childhood and early adolescence as predictors of depression symptoms
Authors: Sikora Renata 
Published: December 2016

AbstractThe study aims to answer following questions: (1) What are the risk behaviors among children at late childhood and early stage of adolescence? (2) What are the differences between boys and girls concerning problem behaviors? (3) Do risk behaviors predict symptoms of depression? Participants fulfilled the set of three tools: (1) Children Depression Inventory authored by M. Kovacs (1992); (2) List of experienced risk behaviors and (3) List of open questions concerning the knowledge and experience with smart drugs. The study group consisted of 130 boys and girls attending the fifth and sixth grade of primary school. The study shows differences between boys’ and girls’ risk behaviors, as well as the similarities. The findings indicate that gender-related disparities in problem behaviors exist even at the early stages of puberty. Boys under one parent custody declare significantly more risk behaviors than girls under one parent custody. Finally, the symptoms of depression were predicted by cumulative number of risk behaviors and – on tendency level – by type of parental custody.

Published: December 2016

Abstract
This article is a case study of a 28-year-old patient diagnosed with F23. The report is preceded by an extensive literature review describing the situation of the mentally ill, in which psychiatry intermingles with spirituality and the sacrum.
The aim of the study was to investigate the relationship between religion/spirituality and schizophrenia as well as to draw attention to the complex problem of differential diagnosis of religious and spiritual problems. When is psychiatric treatment enough and when is intervention of a priest really essential?
The authors discuss the problem of mental disorders in connection with religion and spirituality in the clinical context. The article shows that it is very important that the processes of diagnosis and treatment take into account the patients’ individual traits, beliefs, values and spirituality.

Published: December 2016

Abstract
Let N be a semiprime right near-ring and I a semigroup ideal of N. A map f : N → N is called a multiplicative generalized (θ, θ)–derivation if there exists a multiplicative (θ, θ)–derivation d : R → R such that f(xy) = f(x)θ(y) + θ(x)d(y), for all x, y ∈ R. The purpose of this paper is to investigate the following: (i) f(uv) = ±uv, (ii) f(uv) = ±vu, (iii) f(u)f(v) = ±uv, (iv) f(u)f(v) = ±vu, (v) d(u)d(v) = θ ([u, v]), (vi) d(u)d(v) = θ (uov), (vii) d(u)θ(v) = θ(u)d(v).

Bildung und soziale Bewegungen – eine konzeptionelle Einführung
Authors: Miethe Ingrid , Roth Silke 
Published: December 2016

Abstract
Der Zusammenhang von Bildung und sozialen Bewegungen wird bislang von der Erziehungswissenschaft wie auch in der Bewegungsforschung weitgehend ignoriert. Wir argumentieren in diesem Beitrag, dass eine stärkere Verschränkung dieser Forschungsperspektiven für beide Seiten fruchtbar wäre. Wir identifizieren individuelle und kollektive, formelle und informelle, intendierte und nichtintendierte Bildungs- und Lernprozesse, die in sozialen Bewegungen und Bewegungsorganisationen stattfinden. Diese Bildungsprozesse analysieren wir in Bezug auf vier Aspekte: 1) Bildung als Gegenstand sozialer Bewegungen, 2) Individuelle Bildung in und durch soziale Bewegungen, 3) Kollektive Bildungsprozesse, 4) Soziale Bewegungsorganisationen als lernende Organisationen.
Globales Lernen – Lernprozesse und politische Aktion
Authors: Overwien Bernd 
Published: December 2016

Abstract
Globale Fragen werden im deutschen Bildungssystem bis heute nicht prioritär bearbeitet. Nichtregierungsorganisationen sind oft zwischen politischer Aktion und politischer Bildung tätig. Akteure aus diesem Feld waren es, die globale und Nachhaltigkeitsfragen zunächst in die außerschulische Bildung trugen und dann auch schulische Lernprozesse mit beeinflussten. In diesem Beitrag wird das Konzept Globales Lernen vorgestellt, das sich aus einem Wechselspiel zwischen diesen Akteuren und wissenschaftlichen Herangehensweisen entwickelt hat. Anschließend wird die Rolle der NRO genauer diskutiert. Im Zusammenhang damit geht es schließlich um informelles Lernen in politischer Aktion als einen weiteren Lernhorizont.
Bildung im Dissens – Individualität, Kollektivität und Erkenntnis im Kontext der Neuen Frauenbewegung
Authors: Maurer Susanne 
Published: December 2016

AbstractAuf der Materialbasis biographischer Interviews mit AkteurInnen der Neuen Frauenbewegung (Geburtsjahrgänge 1940ff. und 1955ff.), die im Kontext des 2014 konstituierten Forschungsnetzwerkes „Bildung und Soziale Bewegung“ einer erneuten Betrachtung unterzogen wurden, stellt der Beitrag einen systematischen Zugang zur Erschließung von Bildungsdimensionen Sozialer Bewegungen zur Diskussion. Kennzeichnend für diesen Zugang ist die Verschränkung von drei unterschiedlichen Perspektiven: Dies ist zum einen der Blick auf einzelne Lebensgeschichten und individuell-subjektive Erfahrungen, die sich mit sozialen Bewegungen verbinden, zum anderen der Blick auf die Binnen-Dynamiken Sozialer Bewegungen, die zur kollektiven Erfahrungs-Bildung beitragen, und zum dritten der Blick auf Erkenntnis- und Theoriebildungsprozesse, die von sozialen Bewegungen inspiriert sind bzw. in deren Kontext stattfinden. Welche Qualitäten Bildung im Wechselspiel zwischen diesen drei Dimensionen annehmen kann, wird im Artikel exemplarisch aufgezeigt.
Nach der ‚Flüchtlingskrise‘: Mehr Fragen als Antworten
Authors: Roth Roland 
Published: December 2016

Abstract
So positiv man die Willkommenskultur bewerten mag, die bei der Aufnahme der Geflüchteten entstanden ist: Es ist keine ausgemachte Sache, dass die offene Haltung der Bevölkerung und die neu entstandene Kooperationskultur vor Ort von Dauer sein werden und zur Integration der Geflüchteten beitragen. Roland Roth widmet sich in seinem Beitrag den kritischen Aspekten. Auch wenn viele pragmatische Lösungen gefunden wurden, zu denen vor allem die Zivilgesellschaft beigetragen hat: Die Flüchtlingsfrage als solche bleibt politisch ungelöst. Inwieweit die Integration Geflüchteter Auswirkungen auf den sozialen Zusammenhalt hat, entscheidet sich auch daran, inwieweit es gelingt, die Konfliktlinie ,Öffnen vs. Schließen’ zu zivilisieren.

New woodland beetle species (Coleoptera) in Estonian fauna. 2.
Authors: Süda Ilmar 
Published: December 2016

Abstract
The article presents an annotated list of 99 new beetle species for Estonia (mainly woodland ones) along with their faunistic data. Most of the material has been collected by the author using trunk window traps within the framework of various research and monitoring projects in 2011–2015. In addition, the work comprises a number of unpublished new species, which were revealed in the material of older collections. These originate mainly from the coleopterologist J. Miländer’s beetle collection preserved at the Estonian University of Life Sciences (finds from the period of 1930–1982) and from the private collection of zoosemiotist A. Turovski. 13 species are new for the fauna of the whole Baltic region. Three species are new for Northern Europe: Triplax carpathica Rtt. (Erotylidae), Phloiotrya subtilis (Rtt.) (Melandryidae) and Carpophilus truncatus Murray (Nitidulidae). Triplax carpathica Rtt. (Erotylidae) and Clypeorhagus clypeatus (Hampe) (Eucnemidae), each known only from a single locality, belong to the European IUCN Red List. Two discovered species, Airaphilus perangustus Lindberg (Silvanidae) and Ochthebius czwalinai Kuwert (Hydraenidae), are known for their very restricted spreading area in Europe. For a large part of the new species (36 out of 99) Estonia lies on the northern edge of their areal. These species have not yet been recorded north of Estonia in Finland, where the beetle fauna is studied better. For two Nitidulidae species, Carpophilus marginellus Motsch. and Glischrochilus quadrisignatus (Say), fast spreading over Estonia was registered in the last five years. Somewhat earlier, a species closely related to the latter, Glischrochilus grandis (Tournier), showed the same tendency of fast spreading in Estonia. Six species, Pityophthorus glabratus Eichhoff (Curculionidae), Dirrhagofarsus attenuatus (Mäklin) (Eucnemidae), Hypebaeus flavipes (F.) (Malachiidae), Dacne notata (Gmelin) (Erotylidae), Aulonothroscus brevicollis (Bonv.) (Throscidae) and Carpophilus dimidiatus (F.) (Nitidulidae) have to be excluded from the list of Estonian fauna due to wrong identification.
