Approximate Solution of Schrödinger Equation with Pseudo-Gaussian Potential Viewed as a Perturbation
Authors: Iacob Theodor-Felix , Lute Marina , Iacob Felix
Published: January 2016

We consider the Schrödinger equation with pseudo-Gaussian potential and point out that it is basically made up by a term representing the harmonic oscillator potential and an additional term, which is actually a power series that converges rapidly. Based on this observation the system can be considered as a perturbation of harmonic oscillator. The perturbation method is used to approximate the energy levels of pseudo- Gaussian oscillator. The results are compared with those obtained in the analytic and numeric case.
Complex Impedance of Manganese Ferrite Powders Obtained by Two Different Methods
Authors: Mălăescu I. , Lungu Antoanetta , Marin C. N. , Vlăzan Paulina , Sfirloagă Paula
Published: January 2016

Two samples of manganese ferrite powder were obtained by the calcination method (sample A) and hydrothermal method (sample B). The crystal structure of the samples has been determined using X-ray diffraction analysis (XRD). The results shown that the sample A has three phases (FeMnO3, Mn2O3 and Fe2O3) and the prevailing phase is FeMnO3 with perovskite structure and the sample B has only a single phase (MnFe2O4).

The grain morphology was analyzed by scanning electron microscopy (SEM) and the compositional analysis was done by energy dispersive spectroscopy (EDAX).

Measurements of the frequency (f) and temperature (T) dependent complex impedance, Z(f, T) = Z’(f, T) - i Z’’(f, T) of the samples over the frequency range 20 Hz - 2 MHz, at various temperature values from 300C to 1100C are presented. From these measurements, we have shown that the temperature dependence of the relaxation time is of Arhenius type, which suggests that the conduction process is thermally activated. The values obtained for the activation energy Ea, are: 16meV (sample A) and 147.65meV (sample B).

Applying complex impedance spectroscopy technique, the obtained results shows the shape of a single semicircle at each temperature over the measurement range, meaning that the electrical process obeys to a single relaxation mechanism. The impedance and related parameters of the electrical equivalent circuit depend on the temperature and the microstructure of samples. The resistive and capacitive properties of the investigated samples are dominated with the conduction and relaxation processes associated with the grain boundaries mechanism..
Influence of Mechanical Stirring on the Crucible Dissolution Rate and Impurities Distribution in Directional Solidification of Multicrystalline Silicon
Authors: Popescu Alexandra , Vizman Daniel
Published: January 2016

In this study, time dependent three-dimensional numerical simulations were carried out using the STHAMAS3D software in order to understand the effects of forced convection induced by mechanical stirring of the melt, on the crucible dissolution rate and on the impurities distribution in multicrystalline silicon (mc-Si) melt for different values of the diffusion coefficient.

Numerical simulations were performed on a pilot scale furnace with crucible dimensions of 38x38x40cm3. The computational domain used for the local 3D-simulations consists of melt and crystal.

The dissolution rate was estimated from the total mass of impurities that was found in the silicon melt after a certain period of time. The obtained results show that enhanced convection produced by a mechanical stirrer leads to a significant increase of the dissolution rate and also to a uniform distribution of impurities in the melt.
Substitution in position 222 of haemagglutinin of pandemic influenza A (H1N1) viruses isolated from pigs in Poland
Authors: Kowalczyk Andrzej , Urbaniak Kinga , Markowska-Daniel Iwona , Pejsak Zygmunt
Published: January 2016

The aim of the study was to monitor genetic diversity and antigenic changes in the genome of influenza A(H1N1)pdm09 viral isolates detected during the post-pandemic period in Poland. Clinical specimens obtained from three suspected cases of influenza were analysed by sequencing. Among the differences identified in amino acids sequences, nine substitutions were located within the antigenic HA1 sites and in five residues forming receptor-binding pocket. The HA(D222G) mutation was shown in the isolate Swine/Poland/134312/12 obtained from a mild case of the disease. It must be emphasized that, in general, clinically mild cases are caused by the viruses in which that specific mutation, i.e. haemagglutinin (D222G), does not occur.

Authors: Krajewska Monika , Czujkowska Agnieszka , Weiner Marcin , Lipiec Marek , Szulowski Krzysztof
Published: January 2016

The paper describes avian tuberculosis in a captive bred cassowary. A two-and-a-half-year-old bird was obtained by a Polish zoo in 2010 from the Netherlands under conditions compliant with the recommendations of the European Association of Zoos and Aquaria. Despite being of small size for the age, the bird appeared healthy and showed no signs of the disease until the day when it was found recumbent in its pen. Later on it was euthanised due to lack of treatment possibilities. Pathological changes typical of avian tuberculosis were found in the liver and spleen. Mycobacterium avium ssp. avium was cultured from both organs.
Photocatalytic reduction of nitro aromatic compounds to amines using a nanosized highly active CdS photocatalyst under sunlight and blue LED irradiation
Authors: Safari Ali , Kazemi Foad
Published: January 2016

A variety of aromatic nitro compounds were chemoselectively reduced to the corresponding anilines using conveniently prepared nanosized CdS as a photocatalyst under the sunlight and blue LED irradiation. The results demonstrated that synthesized CdS nanostructures have the potential to provide a promising visible light driven photocatalyst for chemoselective reduction of nitro aromatics in the presence of nitrile and carbonyl groups to the corresponding amines under both sunlight and blue LED irradiation. Photoreduction of nitro aromatics by the prepared nanosized CdS with high surface area was faster than when using the commercially available CdS under both sunlight and LED irradiation. Nanosized CdS photocatalyst was prepared by a simple method without any capping agent.

Innovative approach to treating waste waters by a membrane capacitive deionisation system
Authors: Biro Miša , Vončina Darinka Brodnjak
Published: January 2016

The application of membrane capacitive deionisation was investigated for treating model water samples and real waste waters from the textile industry. For the pre-treatment of waste waters, nanofiltration was integrated in order to prevent scaling and fouling of membranes and electrodes during membrane capacitive deionisation. Different conditions were applied when treating water samples with membrane capacitive deionisation with the aim of optimising conditions for high desalination efficiency and, consequently, for conductivity reduction. The conductivity of waste waters with high salt concentrations was reduced to the required value, below 1.5 mS cm

Published: January 2016

para-Benzylamine substituted oligophenol was synthesized via enzymatic oxidative polycondensation of 4-(benzylamino)phenol (BAP). Polymerization involved only the phenolic moiety without oxidizing the sec-amine (benzylamine) group. Chemoselective polycondensation of BAP monomer using HRP enzyme yielded oligophenol with sec-amine functionality on the side-chain. Effects of various factors including solvent system, reaction pH and temperature on the polycondensation were studied. Optimum polymerization process with the highest yield (63 %) and molecular weight (Mn = 5000, degree of polymerization ≈ 25) was achieved using the EtOH/ buffer (pH 5.0; 1 : 1 vol. ratio) at 25°C in 24 h under air. Characterization of the oligomer was accomplished by

Published: January 2016

In this article, we generalize some works of Bertolini–Darmon and Vatsal on anticyclotomic L-functions attached to modular forms of weight two to higher weight case. We construct a class of anticyclotomic p-adic L-functions for ordinary modular forms and derive the functional equation and the interpolation formula at all critical specializations. Moreover, we prove results on the vanishing of μ-invariant of these p-adic L-functions and the non-vanishing of central L-values with anticyclotomic twists.
The Bakri balloon implementation during cesarean section without switching to the lithotomy position
Authors: Kaya Baris , Tuten Abdullah , Guralp Onur
Published: January 2016

Bakri balloon implementations for the conservative management of postpartum hemorrhage (PPH) have become more popular in the recent years. The procedure may be regarded as simple, however, it can become a challenging method considering an excessive bleeding patient where there is a race against time. In our daily practice we do not usually use the lithotomy position except for few conditions such as placenta previa, where the lithotomy position is necessary to apply a Bakri balloon during PPH during a cesarean section. Here we would like to present a woman with uterine atony and fundal placenta accreta bleeding, managed with the Bakri balloon without switching to the lithotomy position for the first time in the literature. The bleeding was evaluated successfully with this new method, however, a cesarean hysterectomy was necessary to achieve hemostasis despite the addition of a bilateral uterine artery ligation at the end. The decision to add a vessel ligation to the inflated Bakri balloon should be assessed carefully as uterine artery ligation may be time consuming due to effort of avoiding puncturing the balloon. On the other hand, internal illiac artery ligation may be more advantageous if the surgeon is experienced.
Slovenian Complementary Health Insurance Reform – Dichotomy between the Internal Market and the Social Dimension
Authors: Nikolić Bruno
Published: January 2016

Complementary health insurance is divided between the internal market (market principles) and social dimension, wherein the state has an extremely difficult task, as it must create the conditions necessary for the fair and efficient functioning of the health care financing system. Slovenia has failed to successfully accomplish this task, which consists of both ensuring the social dimension and also facilitating the operation of market principles. The aim of this article is not on the functioning of market principles, which are covered by the field of economics, but is instead on analyzing the dichotomy between the internal market (the rules that govern the functioning of the internal market) and the social dimension (the rules that enable the exercise of the social function), and, in this light, analyzes the legal regulation of the Slovenian complementary health insurance. Analysis of the legal regulation highlights the shortcomings in ensuring the social dimension, shortcomings which are, with the help of the measures proposed in the concluding section of the article, remedied by the author.

Authors: Kupidura Adrianna
Published: January 2016

The inhabitants and local governments may treat landscape heritage resources as a cumbersome legacy, which disrupts development, or may see its potential, which may serve as the cornerstone for building a sense of local identity. These issues shall be of special importance in the case of areas located on the outskirts of cities, which are subject to strong urbanization pressure. New inhabitants of such areas often know nothing about the past and history of the landscape in which they have decided to live.

This article presents two approaches to landscape heritage that can be observed in the southern outskirts of Warsaw. It presents the landscape heritage protection and management policy in those areas, as well as the perception of the elements of this heritage by the local community.

Generational Differences In Organizational Justice Perceptions: An Exploratory Investigation Across Three Generational Cohorts
Authors: Ledimo Ophillia
Published: January 2016

Despite several reviews of generational differences across cohorts regarding their career stages in organizations, relatively few empirical investigations have been conducted to understand cohorts’ perceptions. Hence, there is paucity of studies that explored differences on the construct organizational justice across generational cohorts. The objective of this study was to explore the differences across three generational cohorts (Millennials, Generation X, and Baby Boomers) on dimensions of the organizational justice measurement instrument (OJMI). Data was collected through the administration of OJMI to a random sample size of organizational employees (n = 289). Descriptive statistics and analysis of variance were conducted to interpret the data. These findings provide evidence that differences do exist across cohorts on dimensions of organizational justice. In terms of contributions and practical implications, insight gained from the findings may be used in proposing organizational development interventions to manage multigenerational employees as well as to conduct future research.

Authors: Marczyński Zbigniew , Kowalczykiewicz Katarzyna , Bodek Kazimiera Henryka
Published: January 2016

Introduction: The common bean (Phaseolus vulgaris L.) is an annual plant grown in many countries all over the world including its different varieties in Poland. Herbal raw material are elongated pods – pericarp. Phaseoli pericarpium decreases the glucose blood level. Phaseoli pericarpium extracts manifest duretic properties, can be used in the treatment of edema, kidney diseases with decreased urinary excretion, nephrolithiasis.

Objectives: To investigate the usefullness of selected excipients as carriers of dry extract from Phaseolus vulgaris pericarp.

Methods: The method of direct tableting was used. In the further stage, the obtained tablets were subjected to appropriate tests. The first stage of the study evaluates Prosolv SMCC 50, PROSOLV EASYtab, EMDEX, Carmellose calcium and PRUV. These were used to manufacture 4 batches of tablets. In the second stage, an oral solid dosage was manufactured on the basis of the formulation composition of batch 1 tablets (Phaseoli pericarpium extract, Prosolv SMCC 50, PRUV). Then, different surfactants (cholesterol oxyethylate nTE = 30, cholesterol oxyethylate nTE = 40, Rofam nTE = 50), were successively added to this formulation, to obtain 3 batches of tablets. All 7 batches were manufactured in the Erweka tableting machine. Then, they were subjected to morphological tests and physicochemical evaluation. The release of active substances to 3 selected acceptor fluids (water, artificial gastric juice, artificial intestinal juice) was measured in accordance with the requirements of the general and specific monographs in European Pharmacopoeia 7.

Results: The manufactured tablets had a smooth uniform surface with no stains, spalls or mechanical damage and yellow color originating from the extract. The obtained tablets, with surfactants in their composition, demonstrated pharmaceutical availability slightly higher than batch 1 tablets without surfactants.

Conclusions: Excipients applied in appropriate proportions appear to be useful in the manufacturing of uncoated tablets containing extract of Phaseoli pericarpium.
Ideal and nonideal moral theory for disaster bioethics
Authors: O’Mathúna Dónal
Published: January 2016

Moral theory has generally focused on resolving ethical dilemmas by identifying ethically sound options. Whether the focus is on consequences, duties, principles or virtues, ethical cases are often approached in ways that assume morally sound solutions can be found and followed. Such ‘ideal morality’ assumes that moral goodness is always possible, leaving people confident they have done the right thing. Such an approach becomes inadequate in disaster settings where any good solution is often difficult to see. This paper examines recent work on nonideal moral theory as a useful model for disaster bioethics. This approach views moral dilemmas as situations where no choice is ideal and every option involves some element of unavoidable wrongdoing. Rather than straining for ideal answers, this approach acknowledges that sometimes the lesser of two evils is the best that can be done. Such situations inevitably lead to feelings of regret or guilt, commonly encountered in discussions of disaster bioethics. This paper explores the practical implications of nonideal approaches for disaster responders working in tragic situations.
Charlie Hebdo attacks in the light of Aquinas’ Doctrine of double effect and ignatieff’s lesser evil theory
Authors: Švaňa Lukáš
Published: January 2016

The aim of this paper is to study and analyse the Charlie Hebdo attacks from a methodological and an ethical perspective, concentrating generally, though in some cases indirectly, on the consequences of our actions and the motives behind them. The analysis examines the issues of liberties, freedoms and responsibilities in general and further applies these values to the phenomenon of terrorism in contemporary society. The primary goal of this study is to use the Thomas Aquinas doctrine of double effect and Michael Ignatieff’s lesser evil theory to appraise specific acts of terrorism. The article suggests that certain freedoms should be limited in democratic societies and thus ensure safety.

Published: January 2016

The variability of the mean annual air temperature and precipitation totals in three periods: 1848–2010, 1951–2010 and 1981–2010 was investigated in the large Warta River basin, being the area with lowest rainfall in Poland. For the purposes of research, nine meteorological stations with the longest measurement series were selected. Air temperature increase in this river basin was similar than in neighbouring countries. In the last 30 years this trend kept increasing. The precipitation in the whole studied period was slightly increasing in the northern part of the Warta River basin, but decreasing in the southern part. The mean annual precipitation totals in the catchment area did not change visible. In the period 1981–2010, the precipitation totals show a small increase in the winter and spring and a decrease in summer. A negative influence of this climate change was not visible in the Warta River discharge. The main objectives of this study were the collection long-term records of air temperature and precipitation in the Warta River basin, and the statistical analysis of climate variability.

Authors: Udoekanem Namnso , Ighalo James , Sanusi Yekeen
Published: January 2016

This study examined the drivers of office rents in selected districts of Abuja, Nigeria. These districts are Asokoro, Maitama and Utako. Primary and secondary data were utilized for the study. Primary data include office rental levels and office space data in the study areas for the period 2001-2012, and were obtained through structured questionnaires administered to real estate surveying and valuation firms which are active in the commercial property markets in the study areas. Secondary data for the study were obtained from the National Bureau of Statistics (NBS) and the Central Bank of Nigeria (CBN), and consist mainly of macroeconomic variables in Nigeria during the study period. Using single-equation regression analysis, the developed office rent model accounted for 76%, 72% and 75% of the variation in office property rents in the commercial property market of the Asokoro, Maitama and Utako districts respectively. The study also revealed that real GDP growth and vacancy rate are the major determinants of rental growth in the office property market in the districts of Asokoro and Maitama, while real GDP growth is the major driver of office rents in the Utako district. The socioeconomic implication of the findings is that the government can generate substantial revenue from property rate through sustained commercial property rental performance in the study areas. Such revenue can be deployed to provide and maintain public infrastructure, thereby improving the wellbeing of the citizenry.

Von der kompositorischen Funktion und Stellung der Kratemata im byzantinischen Kirchengesang
Authors: Papachristopoulos Ioannis
Published: January 2016

The Byzantine church chant is a purely liturgical song. The music that is practiced here is primarily linked to the understanding of the text and its comprehension. That’s why the sound-word ratio is very pronounced in the syllabic and semi-melismatic chants. This harmonious relationship between music and poetry is partly destroyed in the very extensive and highly melismatic kalophonic songs, because long note chains are set over a single word, even over the vowel of a single syllable. Closely related to the kalophonic pieces often Kratema are executed, representing the total abolition of the connection between the music and the text message. They are likewise extensive melismata, but have no concrete text and are usually built on the meaningless syllables te-ri-rem. In this study, first some of the different explanations as to the origin and the role of Kratemata in worship events will be presented shortly. The actual core of the investigation are the reflections about what a compositional meaning (in music content, formal, compositional and sound aesthetic way) these pieces have and how they affect the structure and organization of their respective total song (kalophonic piece and Kratema together).
“From Adam to Moses”: the Typology of the Old Testament Characters from the Kontakia of Romanos the Melodist and its Assessment on the Great Canon of Andrew of Crete
Authors: Prelipcean Alexandru
Published: January 2016

The subject of the typological images within the kontakia of Romanos the Melodist, the Byzantine Hymnographer who, through his quill pen, fascinated the entire Byzantine Empire in the sixth century, was developed in several topic-related studies. What in fact is the aim of the present study? It tries, on the one hand, to identify those parts within the kontakia of Romanos that speak directly about the typology of the Old Testament characters (including the chronological period from Adam to Moses), and secondly, to examine how Andrew of Crete, (re)known in the Christian hymnography as the “inventor” of the canon, reflects these typological images approximately two centuries after the death of Romanos. In other words, we are concerned with how the typology is present in the new hymnographic production of the eighth century, known under the title of canon, and how the transition from the typology existing in the kontakion to the one in the canon was achieved.
Music, Ritual and Community among Romania’s Orthodox Pilgrimages
Authors: Bănică Mirel
Published: January 2016

More than 20 years after the fall of the Communist regime, we are witnessing the unprecedented development of religious pilgrimage in Romania, a country where, according to the latest census, 84% of the population self-identifies as Orthodox Christian. Apart from the pilgrimages to well-known destinations (Jerusalem, Rome, etc.) organized by the Romanian Patriarchy’s Pilgrimage Bureau, a separate category is the improvised, hybrid pilgrimages, both religious and touristic, organized by individuals using hired minibuses. This paper offers an ethnographic description of a pilgrimage. The focus is on the relationship between music, ritual, the sacred space of the pilgrimage and the public space. Music is used as a barrier and immaterial border to the ritual space, while in its interior it is better suited for the emotional control and the proper management of pilgrims. The analysis of pilgrimages points to new forms of blending of music and ritual, outside established institutional frameworks, as well as to changing notions of pilgrimage, movement, religious practice and piety.
Chronic stress, hippocampus and parvalbumin-positive interneurons: what do we know so far?
Authors: Zaletel Ivan , Filipović Dragana , Puškaš Nela
Published: January 2016

The hippocampus is a brain structure involved in the regulation of hypothalamic-pituitary-adrenal (HPA) axis and stress response. It plays an important role in the formation of declarative, spatial and contextual memory, as well as in the processing of emotional information. As a part of the limbic system, it is a very susceptible structure towards the effects of various stressors. The molecular mechanisms of structural and functional alternations that occur in the hippocampus under chronic stress imply an increased level of circulating glucocorticoids (GCs), which is an HPA axis response to stress. Certain data show that changes induced by chronic stress may be independent from the GCs levels, opening the possibility of existence of other poorly explored mechanisms and pathways through which stressors act. The hippocampal GABAergic parvalbumin-positive (PV+) interneurons represent an especially vulnerable population of neurons in chronic stress, which may be of key importance in the development of mood disorders. However, cellular and molecular hippocampal changes that arise as a consequence of chronic stress still represent a large and unexplored area. This review discusses the current knowledge about the PV+ interneurons of the hippocampus and the influence of chronic stress on this intriguing population of neurons.
The multi-facet aspects of cell sentience and their relevance for the integrative brain actions: role of membrane protein energy landscape
Authors: Agnati Luigi F. , Marcoli Manuela , Maura Guido , Fuxe Kjell , Guidolin Diego
Published: January 2016

Several ion channels can be randomly and spontaneously in an open state, allowing the exchange of ion fluxes between extracellular and intracellular environments. We propose that the random changes in the state of ion channels could be also due to proteins exploring their energy landscapes. Indeed, proteins can modify their steric conformation under the effects of the physicochemical parameters of the environments with which they are in contact, namely, the extracellular, intramembrane and intracellular environments. In particular, it is proposed that the random walk of proteins in their energy landscape is towards attractors that can favor the open or close condition of the ion channels and/or intrinsic activity of G-protein-coupled receptors. The main aspect of the present proposal is that some relevant physicochemical parameters of the environments (e.g. molecular composition, temperature, electrical fields) with which some signaling-involved plasma membrane proteins are in contact alter their conformations. In turn, these changes can modify their information handling via a modulatory action on their random walk towards suitable attractors of their energy landscape. Thus, spontaneous and/or signal-triggered electrical activities of neurons occur that can have emergent properties capable of influencing the integrative actions of brain networks. Against this background, Cook’s hypothesis on ‘cell sentience’ is developed by proposing that physicochemical parameters of the environments with which the plasma-membrane proteins of complex cellular networks are in contact fulfill a fundamental role in their spontaneous and/or signal-triggered activity. Furthermore, it is proposed that a specialized organelle, the primary cilium, which is present in most cells (also neurons and astrocytes), could be of peculiar importance to pick up chemical signals such as ions and transmitters and to detect physical signals such as pressure waves, thermal gradients, and local field potentials.

With the development of automotive, aerospace and biomedical industry, there is higher demand for exotic alloys, often based on titanium or nickel, though they are hard to machine. Therefore, it is essential to thoroughly understand their behavior during machining. Processes in the cutting zone of said materials are due to the complexity and dynamics defined by specific models. These include some deviations, thus it is essential to improve machining observation methodology, so exhibited errors and deviations are minimal or none. Based on the observations, multifunction measuring system has been designed, which allows simultaneous observation of characteristics such as e.g. cutting forces, deformations and thermal spread without uninterrupting machining process.

Published: January 2016

A double inverted pendulum plant as an established model that is analyzed as part of this work was tested under the influence of time delay, where the controller was fine tuned using a firefly algorithm taking into considering the fitness function of variation of the cart position and to minimize the cart position displacement and still stabilize it effectively. The naturally inspired algorithm which imitates the fireflies definitely is an energy efficient method owing to the inherent logic of the way the fireflies respond collectively and has shown that critical time delays makes the system healthy.

Published: January 2016

Machined surface is one of the most used indicators of workpiece quality. But machined surface is influenced by several factors such as cutting parameters, cutting material, shape of cutting tool or cutting insert, micro-structure of machined material and other known as technological parameters. By improving of these parameters, we can improve machined surface. In the machining, there is important to identify the characteristics of main product of these processes – workpiece, but also the byproduct - the chip. Size and shape of chip has impact on lifetime of cutting tools and its inappropriate form can influence the machine functionality and lifetime, too. This article deals with elimination of long chip created when machining of shaft in automotive industry and with impact of shape of chip-breaker on shape of chip in various cutting conditions based on production requirements.

Authors: Ortiz Manuel , Schotte Marilyn , Winfield Ignacio
Published: January 2016

The family Santiidae consists of five genera and 29 species at present, included in the Suborder Asellota. In the northwest Atlantic this family is represented only by the genera Santia (two species), Halacarsantia (one species) and Spinosantia (one species). The present paper deals with the description of a new species of the genus Halacarsantia, collected at the Sisal Coral Reef System, Yucatan, Veracruz. The new species of Halacarsantia represents the 29th asellote isopod discovered in the Gulf of Mexico and brings the total number of species of Halacarsantia to eight. The main differences between the new species and all others in the genus are: mandibular palp present; frontal lobe 0.5× as wide as maximum width of head, with 18 robust setae; coxae of all pereopods dorsally visible; eyes directly settled on each sides of head. A key to the species of Halacarsantia is included.

Track Dynamic Response At Low Frequencies – Dominant Frequencies
Authors: Moravčík Milan , Moravčík Martin
Published: January 2016

The paper is devoted dynamic effects in the track structure - the quasi-static excitation due to moving load, as the important source for the response of track components in the low frequency area (0 Hz < f < 40 Hz). The low-frequency track (the rail) response is associated with periodicity of wheel sets, bogies, and carriages of passage trains, The periodicity of track loading is determined by so called dominant frequencies f(d) at a position x of the track.
Neglect Of Parameter Estimation Uncertainty Can Significantly Overestimate Structural Reliability
Authors: Rózsás Árpád , Sýkora Miroslav
Published: January 2016

Parameter estimation uncertainty is often neglected in reliability studies, i.e. point estimates of distribution parameters are used for representative fractiles, and in probabilistic models. A numerical example examines the effect of this uncertainty on structural reliability using Bayesian statistics. The study reveals that the neglect of parameter estimation uncertainty might lead to an order of magnitude underestimation of failure probability.

Er ist wieder da - aber woher kam Hitler und aus welchen Quellen schöpfte er bei der Niederschrift von „Mein Kampf“. Roman Töppel, einer der Herausgeber der gerade vorgelegten Edition, geht dieser Frage mit Blick auf das ideologische Kernkapitel „Volk und Rasse“ nach, in dem Hitler die Figur „des Juden“ als Feindbild und Antityp des „rassereinen Ariers“ aufbaute. Seine intellektuellen Stichwortgeber waren dabei, so Töppel nach beeindruckend umsichtiger Recherche, vor allem Houston Stewart Chamberlain, Heinrich Claß, Theodor Fritsch, Dietrich Eckart, Hans F.K. Günther und Alfred Rosenberg, wobei Hitler aber selbst bei seinen bevorzugten Gewährsleuten alles ignorierte, was nicht in sein bereits relativ gefestigtes Weltbild passte.
„Macht’s es unter der Tuchent“

Published: January 2016

Vorspann

Wer an die Geschichte Österreichs nach 1945 denkt, verbindet damit nicht unbedingt Kriegswaffenproduktion, Waffenexporte und illegalen, aber politisch gedeckten Waffenhandel. Gerade in der Ära des sozialdemokratischen Bundeskanzlers Bruno Kreisky galt die Alpenrepublik als Motor einer ausgleichenden Friedenspolitik zwischen den Machtblöcken. Dass das aber nur die halbe Wahrheit ist, unterstreicht Thomas Riegler mit der eindringlichen Schilderung eines Skandals, der Österreichs Politik in ihren Grundfesten erschüttert hat. Neue Quellen geben den Blick frei auf ein kompliziertes Geflecht aus politischen Interessen, wirtschaftlichen Problemen und sozialpolitischen Handlungszwängen, das für die Entscheidungsträger letztlich wichtiger war als Recht, Gesetz und Moral.
