Dynamics of the atmosphere and seismic activity in the Baikal rift zone
Authors: Кочеткова Ольга , Kochetkova Olga , Михалев Александр , Mikhalev Aleksandr , Мордвинов Владимир , Mordvinov Vladimir , Татарников Андрей , Tatarnikov Andrey
Published: January 2016

We study the troposphere dynamics, temperature regime in the stratosphere, upper atmosphere emission, and seismic activity in the Baikal Rift Zone for winters 2011/2012 and 2012/2013. Variations of the lithospheric, tropospheric, stratospheric and mesosphe- ric characteristics occurred either simultaneously or with a time lag during these periods. We found that the wind speed in the lower atmosphere reached a maximum several days before the seismic activity increase in the region. Then, it de-creased to a minimum at the earthquake instant. The periods of this seismic activity growth coincided with episodes of stratospheric warm-ings and with an increase in the 557.7 nm atmospheric emission in the meso-sphere and the low thermosphere (85–115 km). A pos-sible reason for the correlations may be the increased atmospheric effects on mountains, the formation of vertical flows above mountains, and generation of planetary and gravity waves.
Child and adolescent mental health inpatient nursing: A call for action
Authors: McDougall Tim
Published: January 2016

There has been significant public and political interest in access to inpatient beds for children and young people during the last two years. Media stories about young people in police cells, and children travelling many miles from home to receive hospital care, have generated concern about access to help for children and young people in mental health crisis. However, it is not just a lack of beds that has been in the spotlight; the staffing, skill mix and quality of care provided in inpatient child and adolescent mental health services has also been called into question. This article discusses some of the challenges facing the nursing profession and makes some key recommendations for hospital managers, health service commissioners, professional bodies and organisations responsible for commissioning and providing nurse education.

Authors: Masood Barkat , Lepping Peter , Jones Emyr , Morris Martin , Lewis Mike , McEwan Judith , Sussex Paul , Owen Gareth
Published: January 2016

A lack of adequate and accurate data in relation to coercion means that there is little information to guide benchmarking and service planning. The aim of this study was to collate and analyse data for restrictive physical interventions (RPIs) across Wales. All health boards in Wales were asked to provide information on restrictive physical interventions across all specialties. Information requested allowed calculations per 100 admissions and per 100 occupied bed days per month, which reduce bias attributed to levels of admissions and occupancy. Full data sets were obtained for 2013 from all health boards. There was a wide level of variation between health boards. Uniform data gathering is required. Benchmarking may be a useful tool to develop strategies to reduce regional variations.

Aim:

To describe Swedish first-year undergraduate nursing students' attitudes toward care of dying patients. Possible influences such as age, earlier care experiences, care education, experiences of meeting dying patients and place of birth were investigated.

Method:

The Frommelt Attitude Toward Care of the Dying Scale (FATCOD) was used in six universities. Descriptive statistics and regression analysis were used.

Results:

Some 371 students (67.3%) reported overall positive attitude toward caring for dying patients (total mean FATCOD 119.5, SD 10.6) early in their first semester. Older students, students with both earlier care experience and earlier education, those with experience of meeting a dying person, and students born in Sweden reported the highest scores, a more positive attitude.

Conclusion:

Age, earlier care experience and education, experiences of meeting a dying person and place of birth seems to affect students' attitudes toward care of the dying and need to be considered among nursing educators.

Representation of vector fields
Authors: Ramm Alexander G.
Published: January 2016

A simple proof is given for the explicit formula which allows one to recover a \(C^2\) – smooth vector field \(A=A(x)\) in \(\mathbb{R}^3\), decaying at infinity, from the knowledge of its \(\nabla \times A\) and \(\nabla \cdot A\). The representation of \(A\) as a sum of the gradient field and a divergence-free vector fields is derived from this formula. Similar results are obtained for a vector field in a bounded \(C^2\) - smooth domain.

Knowledge of the rheological properties is crucial for the numerical modeling of technological processes. The main objective of this study was to conduct an analysis of the rheological properties of A380.0 (AlSi9Cu3(Fe)) aluminium alloy in the semi-solid state. The results could be used for identification of temperature range of the alloy, where thixoforming processes could be executed. Another purpose of the experimental work could be development of the mathematical models of the alloy apparent viscosity. The significant achievement of this particular study is an application of a viscometer which was specially designed for material tests executed at high temperatures, such as the measurement of liquid or semi-liquid aluminium viscosity. This paper presents the results of a rheological analysis of aluminium alloy.

Authors: Barszcz M. , Paszeczko M. , Lenik K.
Published: January 2016

The paper concerns the research on self-organization of the surface of coating of hypoeutectic alloy Fe-Mn-C-B modified Si, Ni, Cr, Cu with friction with C45 steel. The coatings were obtained by arc welding using a flux-cored wire. Tests of resistance to wear were carried out for hypoeutectic coatings with use of the friction pair pin-on-disc in the conditions of sliding friction, in model lubricating environments. The surface-active (glycerol oil) and inactive (Vaseline grease) lubricant was used. Tribological tests carried out showed that cooperation of hypoeutectic alloy coating with counterbody of C45 steel with lubrication with surface-active lubricant results in a significant improvement in tribological properties than in case of the lubrication with surface-inactive lubricant. The resulting effect is related to the self-organization of friction surface. After deposition and wear resistance tests, the friction surface microstructure was analysed, as well as the surface and depth distribution of the elements.

Authors: Hyrcza-Michalska M. , Kawalla R. , Dembińska J.
Published: January 2016

The paper presents the results of a study of drawability of thin AZ31 magnesium alloy metal sheets. These studies are a continuation of experiences in presenting the characteristics of technological plasticity of strips made of magnesium alloy which have been cast between rolls in vertical and horizontal systems called ‘twin-roll casting’. In the context of previous experiments conducted at the Institute of Material Technology of the Silesian University of Technology in cooperation with the Technical University - Bergakademie Freiberg (Germany), drawability of these strips at elevated temperatures has been comprehensively defined while using forming limit curves. Due to low formability of magnesium alloys at ambient temperature, formability tests - including cup forming tests presented in this paper - have been carried out in heated dies at temperature range of 200°C to 350°C. A modern AutoGrid digital local strain analyzer has been used in the examinations and the method of image analysis of deformed coordination nets has been applied. Quantitative and qualitative impact of deformation temperature upon the drawability effects of AZ31 magnesium alloys products have been evaluated.

Authors: Jędrzejczyk D. , Hojny M. , Głowacki M.
Published: January 2016

The paper presents the results of the application simulating the rolling process of steel in terms of coexistence of liquid and solid phases. The created mathematical models can be the basis for creation of systems that simulate the final phase of the continuous casting process relying on using a roller burnishing machine for continuous casting of steel. For a complete description of the performance of the material during deformation in these conditions, the constructed mathematical model is a fully three-dimensional model and consists of three parts: thermal, mechanical, and density variation submodels. The thermal model allows the prediction of temperature changes during plastic deformation of solidifying material. The mechanical model determines the kinetics of plastic continuum flow in the solid and semi-solid states, and the resulting deformation field. The temperature of the process forces supplementing the description of the performance of the material with a density variation model that allows the prediction of changes in the density of the material during the final phase of solidification with simultaneous plastic deformation. For the purpose built model, experimental studies were performed using a physical simulator Gleeble 3800®. They allowed the determination of the necessary physical properties of the metal within the temperature of change state. In addition to presenting the developed models the work also includes the description of the author’s application that uses the above mathematical models. The application was written in the fully object-oriented language C++ and is based on the finite element method. The developed application beside the module data input, also consist of a module of three-dimensional visualization of the calculations results. Thanks to it, the analysis of the distribution of the particular rolling parameters in any cross-section of the rolled strip will be possible. The paper presents the results of the authors’ research in the area of the advanced computer simulation.

Published: January 2016

The paper presents the results of cold upsetting testing of 16.5 mm-diameter 20MnB4 steel wire rod. The main purpose of the study was to evaluate the ability of wire rod produced in industrial conditions for further cold metal forming. Due to the fact that cracks occurred in the test material at different strain values, the authors made an attempt to answer the question whether there are any crack initiators in the material structure, or the observed cracks are due to the manufacturing process parameters.

In order to determine the causes of cracks appearing during upsetting tests, micro- and macroscopic observation techniques were used. For the macroscopic examination, an Olympus SZ-31 microscope was used, while a Nikon Ma-200 microscope was employed for the microscopic examination. The microscopic examination was carried out both in a light and dark fields. To evaluate the effect of surface topography on the crack formation tendency, the results of macroscopic observation under a magnification from 6.7x to 45x were used.
Development and Modelling of the Method of Mandrelless Small-Radius Tube Bending / Opracowanie I Modelowanie Sposobu Beztrzpieniowego Gięcia Rur Na Małych Promieniach
Authors: Michalczyk J. , Wojsyk K.
Published: January 2016

The paper reports the results of research aimed at creating theoretical grounds for a new method of mandrelless small-radius tube bending (1.5Dr<Rg<2.5Dr, where Dr- tube diameter, Rg- bending radius). As the result of applying such a methodology it is possible to carry out the bending process (with an angle of up to 180°) and obtain an ovalization and wall thinning in the bending area, which are much smaller than those in currently manufactured products. The currently used bending methods and bending equipment are able to achieve a minimum bending radius not less than three times the tube outer diameter. The research hypothesis has assumed the existence of tube bending methods that are more efficient that those known so far. Than methods do not rely on circular bending contours, but instead they may use other shaping die contours which has not been explored yet. Circular benders used in practice fail in that they do not yield the expected results on small radii and do not control the material flow (do not ensure its correct behaviour) in the bending zone. The literature review has shown that there are currently no theoretical studies, numerical analyses and experimental verifications related to the processes of mandrelless tube bending on small radii, i.e. for 1.5D≤R≥2.5D, where: (R - bending radius, D - tube outer diameter) up to an angle of 180°. Due to the lack of studies on this subject, in their approach to the numerical modelling of the problem, the authors of the paper were guided by their own experience in this field and made every effort to make the numerical model reflect the actual process as accurately as possible. They were only aided by the general knowledge accumulated in the literature on numerical modelling. To sum up, the purpose of the publication is to demonstrate that the change in the die recess towards a shape resembling an ellipse results in a change in the characteristics of metal flow (movement) along the tube perimeter and in a change in the stress characteristics and, as a consequence, a change in the tube cross-section in the bending zone. The research discussed in this paper seeks to establish the correct flow of material in the tube cross-section in the bending zone by determining the most efficient bender recess shape and friction surface forming, which will eliminate the excessive ovalization and upper wall thinning. The expected effect of implementing this bending technology will be increasing the flow capacity in energy systems, which will directly translate into a reduction of atmospheric CO emissions due to the lower energy consumption. In addition, the paper has presented the concepts of tools intended for the experimental verification of tube bending process.

Published: January 2016

Thermo-physical and thermodynamic properties of metallic systems represent some of the most important data that allows to describe their behaviour under strictly specified conditions. These data are the basic, input data for simulative programs, which can model this behaviour and they can be applied to real conditions. Method of direct thermal analysis is the one of the methods of enabling to obtain such data. This paper deals with application of this method on particular sample of pure standard material. The experimental laboratory system for thermal analysis Netzsch STA 449 F3 Jupiter was used for experimental measurements. This paper is studying the influence of experimental conditions on the obtained temperature of phase transformations and on shift of phase transformation temperatures with respect to the monitored experimental conditions, accuracy and credibility of the measured data. Acquired values of this data could be significantly influenced by experimental conditions, size (mass) of samples, purity of inert atmosphere and also by regimes of controlled heating and cooling rates.

Published: January 2016

The effects of the change of chemical composition and temperature on the viscosity of CaO-Al2O3-SiO2 oxide system with basicity from 0.78 to 1.63 were investigated in this paper. Experimental measurements of viscosity were performed with use of the high-temperature viscometer Anton Paar FRS 1600. Viscosity was measured in a rotational mode during heating at the rate of 2.2 K/min in the temperature interval from 1673 to 1873 K. Viscosity is often sensitive to the structural changes in molten oxide systems, which implies that the analysis of viscosity is an effective way to understand the structure of molten oxide systems. Exact clarification of the change of structure of the oxide system caused by increased content of CaO was performed by Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy and X-ray diffraction (XRD).

Published: January 2016

The paper presents experimental studies devoted to the convection phenomenon within the steel charge of mixed porosity. Such charges constitute bundles of hollow long elements such as pipes or rectangular sections which are heat treated. A significant portion of the gas phase in the volume of the charge makes that natural convection of the gas occurring within the individual elements may have an effect on the course of heating. To the tests the Schlieren method was used which is one of the optical visualization methods applied to the analysis of the flow phenomena in the transparent and non luminous media such as air or water. The tested samples have the form of porous charge beds made from pipes and rectangular profiles. During the experiments the samples were heating up for the constant heat flux rate. The direction of flux was vertical, from the bottom to the top.

Aluminium alloys are characterized by a low density, acceptable mechanical properties and good technological properties. This unique connection of features made aluminium alloys perfect structural material for the transportation industry. Also, due to their good electrical conductivity they also found application in energy production industry. High mechanical properties and electrical conductivity of the Al-Si alloys with Mg addition may be achieved by heat treatment. However, the highest mechanical properties are achieved in the early stages of age hardening - due to precipitation of coherent phases, while high electrical conductivity may be achieved only by prolonged aging, during precipitation of semi-coherent or fully noncoherent, coarse phases. Carefully heat treated AlSi7Mg alloy may exhibit both fairly high electrical conductivity and slightly increased mechanical properties. The following article present results of the research of influence of heat treatment on the properties and microstructure of sand cast AlSi7Mg alloy. Microstructure observations were performed using light microscopy, scanning electron and scanning-transmission electron microscopy. Hardness and electrical conductivity of the AlSi7Mg alloy were investigated both in as-cast condition and after heat treatment. Maximum hardness of the alloy is achieved after solutioning at 540°C for 8h, followed by 72h of aging at 150°C, while maximal electrical conductivity after solutioning at 540°C for 48h, followed by 96h of aging at 180°C. Increase of the electrical conductivity is attributed to increasing distance between Si crystals and precipitation of semi coherent phases.

The analysis was conducted on the basis of the results of computer modelling (FEM) and experimental investigations on backward extrusion. The boundary conditions for numerical calculations were determined experimentally with respect to the flow curve and mechanical properties of aluminum. The results of investigations into backward extrusion of thin-walled square-sectioned aluminum die stampings might be used as guidelines to develop a technological process for industrial practice.

The Leonardo da Vinci project entitled EViVE - European Values Vocational Education-LLP-LDV / PAR / 2013 / RO / 032), took place between September 2013 and July 2015. In this a project, professors from the Educational Sciences Department of the Lucian Blaga University of Sibiu along with partners from Germany, France, Great Britain, Bulgaria and Turkey were involved. The project stages started with the detection of existing values in vocational education in each country. These values were compared afterwards with the values promoted by the European Union as a standard and in case they did not coincident, the common values in accordance with European values were transmitted. In order to ensure the teaching and learning framework of these values, there had to be accomplished a common curriculum, in which specific national features were inserted, exemplifying how these values can and must be taught. The taught lesson showed the importance of awareness of the teachers in teaching these values during the didactic process, as well as the importance that students, through means of education, have to internalize these values, in order to become fully trained Citizens of the United Europe.

Quality assurance is a key element of engineering education at Deakin University and is monitored through various mechanisms which also include the process of collecting students’ feedback within the Schools and faculties. The information received are then looked at holistically and action plan is developed to implement. This has proven to be very effective to ensure feedback received from the students has been properly addressed.

PURPOSE

The School of Engineering at Deakin University, has initiated the formation of Engineering Educational Quality Working Group (QWG). The aim of QWG is to provide a focal point for learning and teaching quality and its assurance in undergraduate and postgraduate Engineering courses. The school approach complements Deakin University processes of collecting and analysing student feedback on unit curricula design, delivery and facilitator delivery performance; feedback regarding individual facilitator, unit evaluations and graduate course experiences.

DESIGN/METHOD

The data are collected through face to face feedback from both on and off campus students. Feedback received from the end of trimester student evaluation process was also analysed.

RESULTS

The motivation behind the practise is to close the loop for the feedback received from the students and take appropriate action against the feedback. This is to enhance overall delivery of engineering education at Deakin University.

CONCLUSIONS

This paper outlines the activities planned by the QWG and elaborates on quality assurance approaches and key strategies to be implemented by the working group to achieve the desired quality as well as efficacy of those recommendations/actions undertaken at the school level.
Teaching Natural Language Processing (NLP) Using Ontology Based Education Design
Authors: Rehman Zobia , Kifor Stefania
Published: January 2016

It often happens in teaching that due to complexity of a subject or unavailability of an expert instructor the subject undergoes in a situation that not only affects its outcome but the involvement and learning development of students also. Although contents are covered even in such a situation but their inadequate explanation leaves many question marks in students’ mind. Artificial Intelligence helps represent knowledge graphically and symbolically which can be logically inferred. Visual and symbolic representation of knowledge is easy to understand for both teachers and students. To facilitate students understanding teachers often structure domain knowledge in a visual form where all important contents of a subject can be seen along with their relation to each other. These structures are called ontology which is an important aspect of knowledge engineering. Teaching via ontology is in practice since last two decades. Natural Language Processing (NLP) is a combination of computation and linguistic and is often hard to teach. Its contents are apparently not tied together in a reasonable way which makes it difficult for a teacher that where to start with. In this article we will discuss the design of ontology to support rational learning and efficient teaching of NLP at introductory level.
Marketing Management: Realities and Requirements in the Context of Business Globalization and Internationalization of Companies
Authors: Marcu Liana , Ranf Diana Elena , Dumitraşcu Dănuţ Dumitru
Published: January 2016

Romanian organizations must open their doors to the outside, and for that managers must perceive and interpret all incoming signals to withstand competitive pressure to attract and retain customers, to be competent, to achieve maximum efficiency in their business processes.

The purpose of the selective scientific research aims the knowledge of certain issues within the organization, such as: current state of marketing management and customer orientation; specific business marketing management in conditions of business globalization and internationalization of companies; specific customer orientation;

Depending on the objectives pursued, the investigation carried out included two successive researches: an exploratory qualitative research and a descriptive quantitative research. The general conclusion about the state of knowledge on marketing management in the context of business globalization and internationalization of companies is that the majority of respondents are aware of the importance of marketing management to support them when they face the daunting penetration option of global markets;

“Take Home Messages”: The research has shown that the most important measure that organizations are considering in order to improve marketing management and make the organization’s management efficient is to increase the place and role of marketing management in the overall management of the organization.
The Hierarchy of Urban Transport Networks
Authors: Popa Emma , Ghionea Florian
Published: January 2016

At the level of premise, most experts agree that, in urban, traveling public wants so-called ex-ante demand do not get to be fulfilled by transmission system exploit, so-called ex post demand level is lower desires the reasons are complex, but the general idea is the network that descends satisfied offer between the two categories of demand. In this material is presented a mathematical model for evaluating the quality of urban transport networks, the proposed hierarchy is determinate by the post central level approach of ex- ante demand of ex -post ideal. The exploitation of urban passenger transport has led to a custom on improving service: It is believed that multiplying the number of routes or vehicles number will bring the ex post level to ex-ante levels. In this paper is demonstrated that this desideratum is impossible to achieve. Like conclusions: numerical values for ex-ante demand near to ex-post demand; a relatively simple instrument, but consistent, to prioritize urban transport networks; a procedure for determining the profitability of “breakthroughs” in constructive structure that would reduce the distance by setting the limit up to which may increase the fare.

How Accurately Can Convertibles be Classified as Debt or Equity for Tax Purposes? Evidence from Australia
Authors: Fenech Jean-Pierre , Fang Victor , Brown Rob
Published: January 2016

The New Business Tax System (Debt and Equity) Act established a set of criteria by which convertible securities could be classified as “debt-like” or “equity-like” for tax purposes. Using data on 256 convertible issues made in Australia between 2001 and 2012, we show that there is a strong relation between, on the one hand, a convertible’s ex ante classification determined at issuance using the tax criteria and, on the other hand, its ex post classification based on the conversion premium at maturity. We conclude that the criteria have been an efficient means of classifying convertibles. We also find an industry effect where debt-like convertibles are more likely to be associated with the resources, metals and mining firms, whilst equity-like are mainly issued by the finance sector. This finding is consistent with the solution to a finance-sequencing problem in the former case, and the impact of capital adequacy regulation in the latter.
Crimes of the sign: Politics and performatives in the Treason Trials of 1794
Authors: Nurra Linda
Published: January 2016

This paper explores some key topics in the semiotics of law − and the paradoxes related to legality, legitimacy, and interpretation − through a chapter in the history of British radicalism that unfolds around the Treason Trials of 1794. These trials, I argue, staged a wholesale battle around the very nature of the sign. The peculiarities of British treason law and the prosecution’s “constructive” readings made treason wholly into a crime of the sign, framing all of radical culture as criminal and conspiratorial. I argue this by showing how legal meaning, along with guilt and innocence, was negotiated in relation to (1) context, and particularly the French Revolution; (2) the performativity of signs, and most crucially, their capacity for disrupting the status quo; and (3) the dynamic nature of semiosis, whereby historical process and political change cannot be halted or controlled. In the Treason Trials, these concepts are alternately invoked and denied as frames for viewing “factual” evidence and establishing its meanings along partisan lines. Finally, this paper would like to suggest that the legal narratives produced in 1794 can generate insights into discursive strategies still used today to create “facts” and “truths,” shape popular opinion, and justify government interventions.
Burying attitudes in words: Linguistic realization of the shift of judges’ court conciliation style
Authors: Youping Xu
Published: January 2016

Court conciliation conducted by judges in Chinese courts is often seen in a positive light as resolving civil disputes efficiently. However, it is sometimes also severely criticized for judges’ malpractice in pressing parties to settle by revealing adjudication results. Sadly, except for mere criticism against this kind of phenomenon and abstract provisions on forbidding this kind of malpractice, little has been done to provide a detailed description of what it is and how to avoid it. This paper, based on authentic conciliation data and an interview with two judges, intends to conduct a linguistic analysis of the above problem. This paper argues that, while in theory legal discourse should be explicit, judges in court conciliation need to bury their attitudes in words when it comes to the rendering of attitudes and suggestions. This paper first analyzes the dilemma concerning how much pressure to be imposed upon which party, and then analyzes linguistic features of judges’ coercive and persuasive conciliation styles, and finally offers suggestions as to the linguistic shift of conciliation style from coercion to persuasion. This paper concludes that such malpractice as coercing parties to settle may be linguistically avoided when judges learn to bury their attitudes in words and leave parties to make voluntary choices.
Ulisse all’Isola di Circe (Brussels 1650): Operatic Transformation of Classical Tradition and Dissolution of Stoic Problems
Authors: Urbański Piotr
Published: January 2016

The present article is a close reading of the libretto of the first opera (drama musicale) staged in the Netherlands, in Brussels in 1650. The main point of interest is Ascanio Amalteo’s transformation or even breakaway from the classical tradition (esp. Homer and Ovid) to create a work with its own message, quite distant from classical texts but, paradoxically, approaching moral and psychological categories in Neo-Stoic mode. Perhaps it is not by chance that a parallel piece, Calderon’s second play on Circe (after the fiesta entitled El mayor encanto, amor, 1635), i.e. the auto sacramentale entitled Los encantos de la culpa (ca. 1650), is also a significant transformation of the motive done in the spirit of the Counter-Reformation. Both plays are the last allegorical interpretations of Circe myth and for the next two-hundred years the last important literary works about Ulysses.
