Australian rock ’n’ roll gear: From the pubs to museum collections
Authors: McDonald Damian 
Published: January 2018

Abstract
In post-Second World War Australia rock n roll music became a significant expression of youth culture, art, rebellion, entertainment and also an area of employment. The technology that enabled the music – particularly the instruments and amplification – required capital investment to obtain it and expertise to maintain it. The leaders of this product market were in the United States and the United Kingdom, and use of this technology required adaptation and substantial capital outlay. Because of voltage compliance issues, scarcity of overseas products and to defray costs, Australian manufacturers and technical experts used the templates created by overseas makers and developed their own products. Two important examples of these are part of the collection of the Museum of Applied Arts and Sciences: the Wasp amplifier cabinet (used by Deniz Tek of Radio Birdman) and the Maton guitar (used by Harry Vanda of The Easybeats). The Wasp amplifier – along with several other Australian-made amplifiers – developed and survived only in the local rock n roll industry, and were early casualties of globalization. Maton guitars survived and are a significant maker of guitars internationally. The stories of these objects – specifically and more broadly – are examples of artistic and technical, yet also unplanned invention. They are also an important, though not often celebrated, part of why Australian rock music in the 1970s and 1980s was a cultural phenomenon. This article will examine through primary sources and scholarly texts why one product disappeared from the market, while another survived; and where these objects sit in a popular culture museum collection.
Collaborating and co-curating knowledge: Participatory engagement on Twitter between galleries, libraries, archives and museums (GLAM) and education audiences
Authors: Lemon Narelle 
Published: January 2018

Abstract
Galleries, libraries, archives and museums (GLAM) are now actively concentrating on enriching communication across a variety of audiences in varied ways. This focus on communication, and thus engagement, has been significantly influenced by the rise of the Internet, social media and mobile technologies. As new kinds of experiences are tailored, there is a drawing together of networks to produce and explore knowledge, co-curation of experiences and scaffold participatory experiences to engage with objects, spaces and meaning making. This is where social media can provide a flexible and personalized experience that encourages interaction and discussion between visitors, museums and objects underpinned by reciprocity, community, and a shift in the cultural organization as the only expert. The monthly Tweet Chat called #MuseumEdOz is discussed in this article as a way to demonstrate how GLAM organizations, GLAM educators, curators and teachers can engage with institutions, key issues, innovation and objects through the platform Twitter. A discussion critically framing the notion of digital interaction through Tim Ingold’s (2015) lines, intersections and meshworks is presented. The data are explored through the entanglement of lines by digital becoming, visibility and connecting, and reciprocity. Illuminated is the emergent participatory culture, new partnerships, collaborative problem solving and the development of a more empowered sense of citizenship.

Published: January 2018

Abstract
After nearly 50 years of research the Chern conjecture for isoparametric hypersurfaces in spheres is still an unsolved and important problem. Here we give a partial result for CMC hypersurfaces with constant Gauß–Kronecker curvature, mainly using a result given in [3] by Otsuki.
Uniform cover inequalities for the volume of coordinate sections and projections of convex bodies
Authors: Brazitikos Silouanos , Giannopoulos Apostolos , Liakopoulos Dimitris-Marios 
Published: January 2018

Abstract
The classical Loomis–Whitney inequality and the uniform cover inequality of Bollobás and Thomason provide upper bounds for the volume of a compact set in terms of its lower dimensional coordinate projections. We provide further extensions of these inequalities in the setting of convex bodies. We also establish the corresponding dual inequalities for coordinate sections; these uniform cover inequalities for sections may be viewed as extensions of Meyer’s dual Loomis–Whitney inequality.
Are sdAs helium core stars?
Authors: Pelisoli Ingrid , Kepler S. O. , Koester Detlev 
Published: January 2018

Abstract
Evolved stars with a helium core can be formed by non-conservative mass exchange interaction with a companion or by strong mass loss. Their masses are smaller than 0.5 M⊙. In the database of the Sloan Digital Sky Survey (SDSS), there are several thousand stars which were classified by the pipeline as dwarf O, B and A stars. Considering the lifetimes of these classes on the main sequence, and their distance modulus at the SDSS bright saturation, if these were common main sequence stars, there would be a considerable population of young stars very far from the galactic disk. Their spectra are dominated by Balmer lines which suggest effective temperatures around 8 000-10 000 K. Several thousand have significant proper motions, indicative of distances smaller than 1 kpc. Many show surface gravity in intermediate values between main sequence and white dwarf, 4.75 < log g < 6.5, hence they have been called sdA stars. Their physical nature and evolutionary history remains a puzzle. We propose they are not H-core main sequence stars, but helium core stars and the outcomes of binary evolution. We report the discovery of two new extremely-low mass white dwarfs among the sdAs to support this statement.
Diffusion in hot subdwarf progenitors from the common envelope channel
Authors: Byrne Conor M. , Jeffery C. Simon , Tout Christopher A. , Hu Haili 
Published: January 2018

Abstract
Diffusion of elements in the atmosphere of a star can drastically affect its surface composition, sometimes leading to unusual mixtures. These chemically peculiar stars can be identified fromthe presence of unusual lines in their spectra. Some hot subdwarf stars show extraordinary abundances of elements such as lead, zirconium and strontium, while the abundance of helium ranges from practically zero to almost 100 percent across the hot subdwarf population. A sequence of extreme horizontal branch star models was generated by producing a number of post-common envelope objects from red giants. The evolution of these subdwarf progenitors was computed with the MESA stellar evolution code from immediately after envelope ejection right up to the ignition of helium in the core. Envelope abundances were calculated at the zero age horizontal branch for models both with and without the presence of diffusion. A small number of simulations also looked at the effects on radiative levitation of these abundances, to test how well diffusion physics is able to reproduce observational data.
LS IV — 14°116 : A Time-Resolved Spectroscopic Study
Authors: Martin Pamela , Jeffery C. Simon 
Published: January 2018

Abstract
LSIV-14 116 is a very unusual subdwarf B star. It pulsates non-radially with high-order g-modes, these pulsations are unexpected and unexplained, as the effective temperature is 6 000K hotter than the blue edge of the hot subdwarf g-mode instability strip. Its spectrum is enriched in helium which is not seen in either the V361 Hya (p-mode pulsators) or the V1093 Her stars (g-mode pulsators). Even more unusual is the 4 dex overabundance of zirconium, yttrium, and strontium. It is proposed that these over-abundances are a result of extreme chemical stratification driven by radiative levitation. We have over 20hrs of VLT/UVES spectroscopy from which we have obtained radial velocity curves for individual absorption lines. We are currently exploring ways in which to resolve the photospheric motion as a function of optical depth.
Pupillographic campimetry: an objective method to measure the visual field
Authors: Stingl Krunoslav , Peters Tobias , Strasser Torsten , Kelbsch Carina , Richter Paul , Wilhelm Helmut , Wilhelm Barbara 
Published: January 2018

Abstract
Pupillographic campimetry allows measuring the visual field objectively by analyzing the pupil response to perimetric stimuli. One of the drawbacks of this technique, similar to static perimetry, is the need of reliable fixation of the subject. By using stimulus sizes comparable to static perimetry and applying gaze tracking, we enable a retinotopic visual field examination regardless of fixation problems and with an increased stability and improved spatial resolution. Here, we present the results of applying the method in eight normal sighted subjects as well as in three patients suffering from diseases usually diagnosed by perimetry. The results in normal sighted subjects show a reduction in the amplitude of the pupil response with increasing eccentricity as expected. We also demonstrate that gaze-controlled campimetry is able to detect organic visual field defects objectively in a patient group and classify the visual field defects without an organic background. Moreover, we show that our method is able to evaluate the visual field sensitivity loss beyond classical perimetry in patients with late-stage retinitis pigmentosa. Thus, gaze-controlled pupil campimetry can be used in addition to classical perimetry, allowing for an objective monitoring of disease progression, rendering it as a biomarker for novel treatments.

Published: January 2018

AbstractAqueous slurry free radical terpolymerization of acrylonitrile (AN) with vinyl acetate (VAc) and a constant amount of 2-acrylamido-2-methylpropane sulfunic acid (AMPS) using K2S2O8/NaHSO3 redox initiator was carried out in a 15-l continuous stirred tank reactor at constant temperature (60°C) and atmospheric pressure. A three-level response surface method based on central composite design was applied to investigate the effect of VAc concentration (wt%) in monomer mixture, bisulfite- to-persulfate ratio in redox initiator system $\left( {\frac{{{\text{[HSO}}_3^ - ]}}{{[{{\text{S}}_2}{\text{O}}_8^{ - 2}]}}} \right)$ and bisulfite-to-monomer mixture ratio $\left( {\frac{{[{\text{HSO}}_3^ - ]}}{{{\text{AN}} + {\text{VAc}}}}} \right)$ on the monomer conversion percentage to polymer, intrinsic viscosity [(η)] and sulfur end groups (SEG) index of the prepared polymers. Experimental results showed that the optimum conditions for synthesis of AN-VAc-AMPS system can be addressed as VAc=9 wt%, $\left( {\frac{{[{\text{HSO}}_3^ - ]}}{{[{{\text{S}}_2}{\text{O}}_8^{ - 2}]}}} \right) = 9.6$ and $\left( {\frac{{[{\text{HSO}}_3^ - ]}}{{{\text{AN}} + {\text{VAc}}}}} \right) = 0.027.$ Monomer conversion percentage to polymer, intrinsic viscosity and SEG index under optimum conditions were 75%, 1.38 dl/g and 190, respectively. The synthesized polymer under these optimum conditions can satisfy the requirements for acrylic fiber production in which its characterization was confirmed with Fourier transform infrared spectroscopy, nuclear magnetic resonance, elemental analysis, X-ray diffraction, differential scanning calorimetry and scanning electron microscope.

Equilibrium shapes of charged droplets and related problems: (mostly) a review
Authors: Goldman Michael , Ruffini Berardo 
Published: January 2018

AbstractWe review some recent results on the equilibrium shapes of charged liquid drops. We show that the natural variational model is ill-posed and how this can be overcome by either restricting the class of competitors or by adding penalizations in the functional. The original contribution of this note is twofold. First, we prove existence of an optimal distribution of charge for a conducting drop subject to an external electric field. Second, we prove that there exists no optimal conducting drop in this setting.

In this case, the mappingΦ:𝔗⁢(M)→MP{\Phi:\mathfrak{T}(M)\to M_{P}}given byΦ⁢(x/s)=x/s{\Phi(x/s)=x/s}is anR-module homomorphism. The restriction of Φ toMis also anR-module homomorphism fromMintoMP{M_{P}}given byΦ⁢(x)=x/1{\Phi(x)=x/1}for everyx∈M{x\in M}. A nonnil submoduleNofMis said to be Φ-invertible ifΦ⁢(N){\Phi(N)}is an invertible submodule ofΦ⁢(M){\Phi(M)}. Moreover,Mis called a Φ-Prüfer module if every finitely generated nonnil submodule ofMis Φ-invertible. If every nonnil submodule ofMis Φ-invertible, then we say thatMis a Φ-Dedekind module. Furthermore,Mis said to be a Φ-Bezout module ifΦ⁢(N){\Phi(N)}is a principal ideal ofΦ⁢(M){\Phi(M)}for every finitely generated submoduleNof theR-moduleM. The paper is devoted to the study of the properties of Φ-Prüfer, Φ-Dedekind and Φ-BezoutR-modules.

Published: January 2018

Abstract
Demand for germanium (Ge) is rapidly growing in recent years in various fields including semiconductors, aerospace, and solar cells. However, the Ge resources are very limited in the world. Hence, in this work, microwave-assisted leaching and conventional leaching methods are employed for the leaching of Ge from the Ge-rich lignite ash (GA). The effects of leaching temperature, leaching time, initial acid concentration, oxidizing agent amount, and stirring speed on leaching of Ge were investigated and microwave-assisted and conventional methods of leaching were compared. Here, HCl solution is used as a leaching agent, and MnO2 is used as an oxidizing agent. From the results, the leaching rate of Ge was found to be 89.49% in the microwave-assisted method, and 83.62% in the conventional leaching method. The optimal conditions for microwave-assisted method include a leaching temperature of 65°C, a leaching time of 90 min, an oxidizing agent amount of 10 g/l, an initial acid concentration of 10 mol/l, and a stirring speed of 250 rpm. The leaching rate of Ge significantly improved in the microwave-assisted method as compared to the conventional method. Therefore, the microwave-assisted method is a suitable method for the leaching of Ge from the GA and is a novel way for the efficient utilization of Ge concentrate.

Published: January 2018

Summary
The paper presents novel data on international human rights in the Czech legal education. The importance of international human rights treaties and case-law of human rights bodies in the domestic practice gradually increases, therefore the students of Czech law schools should be familiar with the grounds of the sub-discipline, especially with the interpretative techniques used by international human rights bodies. The paper categorizes the approaches which the Czech law faculties employ as regards educating students in international human rights field and evaluates advantages and disadvantages of the approaches implemented by individual law schools. Finally, the paper identifies weak spots in Czech legal curricula and proposes some ideas for improvement.
Limitations of Comparative Advertising Permissibility: Denigration/Disparagement
Authors: Andraško Jozef , Sopúchová Soňa Ralbovská 
Published: January 2018

Summary
The authors analyse legal regulation of comparative advertising that refers to situations when competitor’s goods or services are expressly or by implication identified in any form of advertising. Such an analyse is made from the perspective of European Union, United States and Indian legal orders. In particular, the main focus is on the issue of denigration or disparagement as limitations of comparative advertising permissibility. In addition, significant case law with respect to aspects of denigration or disparagement within issue of comparative advertising is analysed. Such an analysis would lead to identification of differences that arose within comparison of various legal orders and case law. These findings are necessary in order to make a conclusion which approach regarding to the issue in question is the most preferable.
Brexit, EEA and the Free Movement of Workers: Structural Considerations on Flexibility
Authors: Stehlík Václav 
Published: January 2018

Summary
The article focuses on the regulation of the free movement of workers under Agreement on the European Economic Area in the light of the considered accession of the United Kingdom to this agreement after the Brexit takes place. The participation in the European Economic Area would keep the United Kingdom part of the EU internal market including the free movement of workers. The article tries to answer the question on the degree of flexibility in the EEA Agreement which would give space for the UK to pursue its own policies on the movement of workers. The article argues that structurally the EEA Agreement gives a space for some flexibility, however, only in case of very specific circumstances.
Residential Co-Ownership within the Superficiary Right of Building – Theoretical Hotch-Potch or Practical Reality?
Authors: Petr Pavel 
Published: January 2018

Summary
The new approach to a thing enables the concept of residential co-ownership within the superficiary right of building. Residential co-ownership may be created where a building with at least two apartments forms the component part of the immovable thing. The superficiary right of building is established as a derivative of the superficies solo cedit principle. Therefore, it requires the accession of building and land. The building is no longer a separate thing in the legal sense, but part of the superficiary right of building. If the building which is part of the superficiary right of building contains two apartments, then residential co-ownership may also be established as part of the superficiary right of building
Information and Communication in Public Administration in the Context of Management Control Functioning in the Public Finance Sector in Poland
Authors: Mituś Ambroży 
Published: January 2018

Summary
The aim of this article is to present the essence and significance of information and communication in public administration in the context of the management control. Broadly understood information in public administration allows both to control the activity of this administration and to make correct decisions and actions in order to perform public tasks effectively. Therefore, the existence of a proper system for sharing and exchanging information is an essential component of the management control, ensuring the execution of the tasks and objectives in a way that is consistent with the law, effective, efficient and timely. The article points to i.a. the types of information and means of communication that may be deemed effective or legally acceptable tools for conveying information and communicating in public information. In this context it should be emphasised that - in particular - sharing public information requires that a relevant form be retained and a proper sharing procedure be followed.
Property Regimes of Spouses and Partners in New EU Regulations – Jurisdiction, Prorogation and Choice of Law
Authors: Valentová Lucia 
Published: January 2018

Summary
There are millions of international couples living and working in the EU. Not a small number of those face difficult time when their marriage or partnership comes to an end. On top of dealing with loss, the couples have to navigate through a lot of administrative and legal obstacles to figure out the division of their property located in different Member States or governed by different national law. These proceedings are lengthy and expensive. European Commission, aware of the issue their citizens face, introduced two proposals for regulations on matrimonial property and property of registered partners. In 2013 the proposals did not get the required unanimity, in 2016 they are being re-introduced in enhanced cooperation.
The Equilibrium on Money Market and the Central Bank Issuing Policy
Authors: Pospíšil Richard 
Published: January 2018

Abstract
The issue of money and establishing interest rates are the main activities of central banks. Th rough this, the banks immediately influence the behaviour of households, companies, financial markets and the state with the impact on real outcome, employment and prices. When monitoring the issue of money, it is necessary to focus not only on its volume, but also on the attributes and functions carried by money. Among the first economists who considered the quality monetary aspect were J. Locke, D. Hume, D. Ricardo and others. The founders of modern monetarism of the 20th century were I. Fisher and M. Friedman. Fisher was the first to define the equation of monetary equilibrium in the present-day form. The objective of the paper is to point out different approaches to the equation and its modifications and different meanings of its variables. As regards the monetary aggregate M - Money - the paper also deals with the denomination of the aggregate to its various elements, which is significant for fulfilling monetary policy targets. This approach is very important especially at present in the time of crisis when central banks are performing their policy considering contradictory targets of price stability and economic growth.
