In the first part of this paper has discussed about the
basic properties of cyclide Dupin, and has gave some examples of
their applications: three ways of solving the problem of Apollonius
exclusively by means of compass and ruler, using identified properties
cyclide Dupin, that is, given a classical solution of the problem.
In the second of part of the work continued consideration of
the properties of cyclide Dupin. Proposed and proved the possibility
ask cyclide Dupin arbitrary ellipse as the center line of the
forming a plurality of spheres and a sphere with the center belong -
ing to the ellipse. Proved the adequacy of this information is used
to build the cyclide Dupin. Geometrically proved that the focal line
of cychlid are not that other, as curves of the second order. Given
the graphical representation of the focal lines of cychlid. Shown
polyconic compliance focal lines of cichlid of Dupin, which is
considered in all four cases. The proposed formation of the hyperbolic surfaces of the fourth
order with one or two primary curves of the second order, in this
case ellipses. Apply sofocus this ellipse the hyperbola. Although the
primary focus of the ellipse lying in the plane of the hoe, with the
center coinciding with the origin of coordinates, is stationary, and
the coordinate system rotates around the z axis. Then the points of
intersection of the rotating coordinates x and y with a fixed ellipse
specify new values for the major and minor axis of the ellipse with
resultant changes in the form defocuses of the hyperbola. Although
this modeling is not directly connected with Cychlidae Dupin, but
clearly follows from the properties of its focal curves – curves of
the second order. Withdrawn Equations of the surface and its throat.

The paper considers various ways to construct the
intersection curves of surfaces, available in the scientific literature.
The analysis shows that the exact build intersection surfaces finds
extensive practical application when designing constructions from
sheet material, which must be built. In this case, the accuracy of
manufacturing elements construction depends largely on the accuracy
of the projections of the intersection of surfaces on an integrated
drawing. In this work the examples build the intersection
of several complex surfaces 2nd order among themselves and with
the curve line using 2D and 3D technologies. In this case, the accuracy
of manufacturing elements construction depends largely on
the accuracy of the projections of the intersection of surfaces on
an integrated drawing. In this work the examples build the intersection
of several complex surfaces 2nd order among themselves and
with the curve line using 2D and 3D technologies. Provides an
algorithm of building solid model of certain surfaces, which significantly
reduces the time to solving problems at the intersection
of the surfaces, making visibility into the solution, create a realistic
model of the object. In General, this work demonstrates that
one of the stages of further reform in teaching descriptive geometry
is the evolutionary path of development, outlining the many issues
(e.g., intersection of surfaces) using electronic kuhlmann. In this
case, students will receive a decision not by pushing buttons, and
applying the methods of descriptive geometry, simultaneously developing
spatial imagination and computer skills are already in the
first year. And the final stage of teaching descriptive geometry will
transition to 3D modelling, when the above tasks will instantly and

At prompt development of informatization of production
the role of engineering education significantly increases. Graphic
disciplines on technical specialties of higher education institution
are the first professionally focused disciplines which are actively
influencing formation of competences of future experts. Many
problems of improvement of quality of development of difficult
courses of university programs can be solved by use of effective
forms of education. Realization of competence-based approach in
the higher education demands wide use of active and interactive
forms of carrying out occupations in combination with independent
work of students for formation and development of the professional
skills which are trained. Independent work has to bear not
only reproductive functions on fixing of the passable material, but
also to induce students to active self-education, creative preparation
for effective professional activity. Use of computer graphic tasks
with entertaining elements when training students in graphic disciplines
promotes increase of level of informative activity of students,
development of creative abilities and profound studying of a subject.
The new original graphic task on descriptive geometry with use
of computer technologies for students of auto makers is offered.
The graphic task consists in creation of electronic model of the car
as solid-object one of two developed ways of modeling. In the course
of performance of a task students solve the main geometrical objectives
by definition of a form and constructive and geometrical
parameters of the spatial objects entering a car design and in parallel
master 3D modeling in AutoCAD or Solid Works packages.
It is proved that inclusion in educational process of the graphic
task developed taking into account a professional orientation
trained, increases its efficiency. The task performed during the first
semester promotes fixing and profound studying of fundamentals
of descriptive geometry and development of computer graphics.
It can be used when studying 3D computer geometrical modeling
for students of the technical directions.

The author shares his experience of training 3D geometric
design competition for technical objects using modern of
CAD-systems. It proposed the idea of development of creative
abilities of students in the process of learning the basics of geometric
modeling by incorporating elements of the structure of the
training methods of self-development. It is noted that the principle
of competition among the students in the group, encourages the
pursuit of the study of modern packages and the acquisition of new
skills. Created aimed at the development of creative abilities formation
technique Olympiad learning objectives based on the real
experience of designing in engineering offices and proposed a new
form of training for a competition at the expense of an additional
self-study students. As the experience of the first 3D-competitions,
the task of a typical section of the course of the IG does not attract
active and creative students who want to learn to work at a high
level and modern packages.
Systematic preparation for the 3D-competition is a necessary
and very useful tool to stimulate and self-study of the subject as
&#34;Fundamentals of geometric modeling.&#34; This subject is not in the
programs of universities, but it is indispensable. The tasks of the
Olympiad are encouraged to include practical design solutions,
both in the solid state, and in surface modeling.
In more complex tasks with surface modeling is particularly
interesting to students. They seek to independently study the theoretical
and practical side of the work in computer-aided design
packages, so the competition celebrated its significant activity. In
tasks you are offered the use of standard methods of practical surface
modeling to create the technical and design form the projections
and conceptual sketches.
The article gives examples of practical solutions, which can be
seen a high level of theoretical and practical training of participants
in 3D geometric design competition, there is speed of execution of
tasks and the ability to solve professional design solutions.

Abstract

BACKGROUND
Biomarkers are well established for diagnosis of myocardial infarction [cardiac troponins, high-sensitivity cardiac troponins (hs-cTn)], exclusion of acute and chronic heart failure [B-type natriuretic peptide (BNP), N-terminal proBNP (NT-proBNP)] and venous thromboembolism (d-dimers). Several studies have demonstrated acute increases in cardiac biomarkers and altered cardiac function after strenuous sports that can pretend a cardiovascular emergency and interfere with state-of-the-art clinical assessment.

METHODS
We performed a systematic review and metaanalysis of biomarker and cardiovascular imaging changes after endurance exercise. We searched for observational studies published in the English language from 1997 to 2014 that assessed these biomarkers or cardiac function and morphology directly after endurance exercise. Of 1787 identified abstracts, 45 studies were included.

RESULTS
Across all studies cardiac troponin T (cTnT) exceeded the cutoff value (0.01 ng/mL) in 51% (95% CI, 37%–64%) of participants. The measured pooled changes from baseline for high-sensitivity cTnT (hs-cTnT) were +26 ng/L (95% CI, 5.2–46.0), for cTnI +40 ng/L (95% CI, 21.4; 58.0), for BNP +10 ng/L (95% CI, 4.3; 16.6), for NT-proBNP +67 ng/L (95% CI, 49.9; 84.7), and for d-dimer +262 ng/mL (95% CI, 165.9; 358.7). Right ventricular end diastolic diameter increased and right ventricular ejection fraction as well as the ratio of the early to late transmitral flow velocities decreased after exercise, while no significant changes were observed in left ventricular ejection fraction.

CONCLUSIONS
Current cardiovascular biomarkers (cTnT, hs-cTnT, BNP, NT-proBNP, and d-dimer) that are used in clinical diagnosis of pulmonary embolism, acute coronary syndrome, and heart failure are prone to alterations due to strenuous exercise. Hence, it is necessary to take previous physical exercise into account when a cardiac emergency is suspected.
Cannabinoid Concentrations Detected in Fatal Road Traffic Collision Victims Compared with a Population of Other Postmortem Cases
Authors: Andrews Rebecca , Murphy Kevin G , Nahar Limon , Paterson Sue 
Published: August 2015

Abstract

BACKGROUND
Acute cannabis consumption nearly doubles the risk of motor vehicle collision resulting in injury or death. Limited data have been published regarding the concentrations of cannabinoids associated with fatal road traffic collisions (RTCs), and these have not previously been compared to a population of other postmortem cases.

METHODS
We conducted analysis for cannabinoids [Δ9-tetrahydrocannabinol (THC), 11-hydroxy-THC, 11-nor-THC-9-carboxylic acid, cannabidiol, and cannabinol], drugs, and alcohol on consecutive fatal RTC cases (100) and non-RTC cases (114) from coroners' jurisdictions in London and southeast England and compared the data.

RESULTS
The incidence of cannabinoids detected in non-RTC and RTC cases was similar (25% vs 21%, P = 0.44), but THC was detected more frequently (90% vs 59%, P = 0.01) and at significantly higher concentrations in the cannabinoid-positive RTC cases than the non-RTC cases (P = 0.01). The distribution of non-RTC and RTC cases over 4 categories of THC concentration was significantly different (P = 0.004). There was no significant difference in the concentrations of other cannabinoids detected between the 2 groups. Cannabinoids were detected in more fatal RTC cases (21) than alcohol &gt;80 mg/dL (17). Detection of other drugs was low compared to cannabis and alcohol.

CONCLUSIONS
These first data on the concentrations of cannabinoids in the postmortem blood of fatal RTC victims compared with a population of other routine coroners' cases highlight the importance of specifically measuring THC concentrations in the blood to aid interpretation of postmortem cases where cannabis may be implicated.
Open Studios is the beginning of a conversation: Creating critical and reflective learners through innovative feedback and assessment in Fine Art
Authors: Pollock Venda Louise , Alden Sandy , Jones Chris , Wilkinson Brenda 
Published: August 2015

Abstract
In recent years, increased attention has been paid to feedback and assessment in Fine Art. This has revealed a need for the pedagogic culture of Art and Design subjects to be better understood, particularly from the perspective of the student experience. Accordingly, this article presents findings from a Higher Education Academyfunded project that investigated feedback and assessment within creative practice through a case study of Newcastle University’s Open Studios (OS) feedback and assessment model. Through this we argue that multifaceted feedback models best address some of the problems surrounding the feedback–assessment relationship in studio-based disciplines, particularly assisting students to develop the critical and reflective capacities on which much studio-based tuition is built. Within this, however, careful consideration needs to be made of the power relationships in studio dialogues. Unlike traditional academic disciplines, the research revealed a premise placed on feedback rather than grades within Fine Art where, as the students put it ‘it’s more about building a practice’.
The influence of MOOCs to enhance graphic design education
Authors: McNamara Patrick 
Published: August 2015

Abstract
There is increased pressure on higher education (HE) graphic design lecturers to provide a more engaged platform for the evolving digitally engrossed student. This article explores Massive Open Online Courses (MOOCs) as an educational experiment to help envision changes in HE design teaching. MOOCs have presented aspects of a plausible, although unresolved, online teaching model that has challenged many long-held beliefs of learning and teaching. This investigation considers aspects of MOOCs and their capacity to drive innovation in design education. It will analyse how these features might alleviate some of the pressures on teachers and enable a deeper dialectic in the learning space. I will argue that the importance of this study rests in the questions it raises about the capacity for design education to exploit the benefits of this ‘massive’ experiment.
Leading creative practice pedagogy futures

Published: August 2015

Abstract
Higher education is experiencing substantial change, with considerable debate regarding the potential of technology within learning and teaching. Whilst technology is driving pedagogic change, there are two key challenges for educators in the creative arts. Maintaining the distinctiveness of the studio learning and teaching experience is paramount for creative practice outcomes. At the same time, direction setting is vital for contemporary and emerging creative practice pedagogy. We suggest that responding to these challenges requires a collaborative action research approach for leaders of learning and teaching, and an effective model of leadership for changing practice. A new integrated model is proposed, drawing upon creative leadership and appreciative enquiry frameworks, for developing and implementing a new technological learning paradigm. The article highlights the important role that learning and teaching leaders can play, through collegial and strategic collaboration across institutions, in shaping creative practice pedagogy futures. It is offered as a provocation for exploration and wider discussion on the issues, possibilities and implications of contemporary models – for learning and teaching and its leadership.
A hipster history: Towards a postcritical aesthetic
Authors: Hill Wes 
Published: August 2015

Abstract
The pejorative term ‘hipster’ has been prominent in popular culture since the early 2000s, typically used in reference to connoisseurs, elites, poseurs, or anyone who is unaware of their own pretentiousness. As cultural stereotypes, hipsters have been allied with a striking diversity of aesthetic forms over the last twenty years, so much so that the trope has less to do with a specific aesthetic style and more to do with the attempt to foster a counter-mainstream sensibility. In this article, I provide an historical backdrop to the rise of the postpostmodern hipster, locating its emergence in the global spread of culture in the 1990s. I argue that the current pervasiveness of so-called ‘hipster hate’ – visible on the Internet and on social media platforms such as Twitter – is exemplary of a post-critical perspective, where the hipster stereotype serves as a point of distinction that reinforces the ideologies of cultural pluralism.
The ambiguity of seamlessness: The Skin Ego and the materiality of fashion
Authors: Lee Yeseung 
Published: August 2015

Abstract
This article examines the materiality of fashion and the role it plays in the continuous making of personal and social subjectivities, through the author’s own experience of making seamless woven garments. Psychoanalyst Didier Anzieu’s influential notion of ‘the Skin Ego’ theorizes the initial formation of human subjectivity based on the tactile interaction between the mothering environment and the baby. As a garment maker, the author analyses the woven surface or garment as the extension of the Skin Ego, and inquires into the ways that the ‘separation’ from the earliest relationship and the unending attempt to repair this ‘cut’, might become figured in the ambiguity that is found in the seams and edges of garments. Integrating references from the fields of psychoanalysis, anthropology and cultural studies, this article suggests that the process of making and using garments – regarded as the interaction between human and material, as well as interpersonal, interaction – successfully reveals the ambiguities inherent in modern subjectivity.
What is she wearing? Gender division and the dilemmas of female agency in television news
Authors: Bliss Catherine 
Published: August 2015

Abstract
Patricia Holland’s essay ‘When a woman reads the news’ first appeared in 1987. In this text, Holland extended feminist visual culture theory into the discussion of women in television and highlighted how female newsreaders were subject to scrutiny as to their appearance. The purpose of this article to revisit the subject in a contemporary context in order to examine why this emphasis on physical appearance, and especially attire, still exists some three decades later.
In order to discuss the sartorial dilemmas that women in news media face, in particular in the digital era when praise or censure can be immediately communicated, the article uses semiotic deconstructions of three specific broadcasts, BBC Breakfast and The Six O’Clock News and Channel 4 News, to consider how dress operates as part of a discourse of power and gender reinforcement. The article also offers three strategies, which women newsreaders appear to adopt in their attire in order to deal with the perceived issue of femininity and its appropriateness in the context of the newsroom. The larger implications of the article are that feminist efforts towards less focus on women’s appearance and attire could be seen to have had little effect, however, Judith Butler’s post-feminist writings offer an alternative perspective whereby femininity is reconfigured as a positive rather than a negative attribute.
A collaborative development of an artistic responsive fashion collection
Authors: Pesonen Liisa , Wikström Valtteri , Mikkonen Jussi 
Published: August 2015

Abstract
This article focuses on the merging of technology, media art and fashion design in a specific project, Immediate Invisible (2013). Immediate Invisible was a collaborative fashion-collection project. The result consists of six modular outfits with built-in electronics for displaying physiological responses as audio output. The idea plays with a recurring theme in fashion: revealing and concealing, which is also linked with the increasing use of sensors in contemporary everyday life.
The process of making Immediate Invisible is described from the point of view of the artist and expert’scollaboration, by presenting e.g. selected materials, technology and sound, and how they affected one anotherwhen merged to create the outcome: ‘a hearing device for the body’. Exquisite Corpse by Friswell (2010), isused as a metaphor for the collaborative design method, where all disciplines had equal value in creating themodular and functional outcome. An examination of the tangible outcome is presented as the findings. Theneeds of different disciplines affected each other both as limitations and as artistic input. The project differsfrom other similar wearable projects with its modularity, and from conventional fashion due to the use ofresponsive sound as an inherent part of its aesthetics.
