Dynamics of the η' meson at finite temperaturePerotti, Elisabetta January 2014 (has links)
At the present time it is unknown how the U(1)A anomaly of Quantum Chromodynamics behaves at high temperatures. We therefore want to look for thermal changes of the effects of the anomaly. For example, by studying the properties of the η' meson at high temperatures it would be possible to deduce important information on the axial anomaly, thanks to the deep connection between them. In this thesis the width of the η' as a function of the temperature is studied in the framework of large-Nc Chiral Perturbation Theory, at next-to-leading order, and in the corresponding Resonance Chiral Theory. We calculate the width increase due to scattering with particles from the heat bath, which we assume to consist of a pion gas. We compare the results obtained in both frameworks and as expected we find a smaller, but still consistent width increase when the more realistic resonance exchange is taken into account. The results suggest that the in-medium width of the η' may increase up to ΔΓ<img src="http://www.diva-portal.org/cgi-bin/mimetex.cgi?%5Capprox" /> 10 MeV at a temperature of T<img src="http://www.diva-portal.org/cgi-bin/mimetex.cgi?%5Capprox" /> 120 MeV. We find therefore a width increase of considerable size, comparable to the inverse lifetime of the fireball created in relativistic heavy-ion collisions. In other words, our results suggest that it may be possible to study experimentally how the properties of the η' change at high temperatures.

Metabolic syndrome marker cut-off points and target organ damage revisited in an urban South African cohort : the SABPA study / Svelka HoebelHoebel, Svelka January 2012 (has links)
Objectives: The aim of this study was to determine the prevalence of MetS among
different African populations using the new Joint Statement Criteria. Hereafter we
aimed to determine whether waist or neck circumference is the best predictor of
MetS risk after ethnic, gender and age-specific cut-points were developed. Lastly, we
aimed to determine whether afore-mentioned cut-point can predict
albumin:creatinine ratio as a marker of target organ damage. Methods: The study
sample (N=409) comprised of urban African (men, N=101; women, N=99) and
Caucasian (men, N=101; women, N=108) teachers from the Dr. Kenneth Kaunda
Education district in the North-West Province, South Africa. Participants were aged
between 25 and 65 years. Anthropometric measurements, albumin:creatinine ratio
and other markers of the metabolic syndrome (MetS) (systolic and diastolic blood
pressure [SBP and DBP], glucose, triglycerides [TG] and high density lipoprotein
[HDL]) were determined. Results: Africans (65 and 63 % for men and women) and
Caucasian men (73%) showed high prevalence of MetS; ROC analysis determined
neck circumference (NC) cut-points of 39 and 35 cm for young and older African
men, 32 and 35 cm for young and older African women, 40 and 41 cm for Caucasian
men and 34 and 33 cm for Caucasian women. This NC cut-point can be used to
determine metabolic syndrome risk in all groups, except in African women; ROC
developed waist circumference (WC) cut-points were 91 cm for all African male
groups, 84, 81 and 84 cm for young, older and total group of African women.
Suggested WC cut-points for Caucasian men were 93 cm for the young group and
97 cm for older as well as total Caucasian male groups, while cut-points for
Caucasian women were 87 cm, 79 cm and 84 cm for young, older and total
Caucasian women. These WC cut-points were good measures of metabolic
syndrome risk in all groups; neither cut-point of WC nor NC could increase the risk of
albumin:creatinine ratio. Conclusion: African women as a group present with few
MetS risk factors and glucose is associated with renal function risk in Africans; NC
cut-points may be used as an additional anthropometric marker to predict the
metabolic syndrome in a South African cohort, but not in African women; WC cutpoints
demonstrated to be good predictors of the metabolic syndrome in the same South African cohort, especially among men; WC would seem to be the best
measure of MetS risk in all African populations, although NC can also be used for
this purpose in all African populations, except in African women. / Thesis (PhD (Human Movement Science))--North-West University, Potchefstroom Campus, 2012

Translation of humour with special reference to the cartoons in 'Leman' and other popular weekly humour magazines of TurkeyYakin, Orhun January 1999 (has links)
In this dissertation, the various strategies of humour translation have been analysed by taking various cartoons with speech bubbles from the popular Turkish humour weekly magazine Leman and other similar publications. Generally considered as an extremely problematic, sometimes next to impossible, task within the translation studies, humour translation requires and deserves special attention since, as it was explained in the related sections, it may unite or separate people within the context of one single joke. As we also have stated elsewhere in the text, the description of both humour and translation, as two separate concepts, are not available in certain and decisive terms. This is especially true for the concept of humour which also covers the areas of laughter, jokes, wit, satire, irony and many others which are all interchangeable with each other. This fact makes an all-round definition very difficult. We also tried to show that, the visual humour or the visual aspect of humour could be a valuable asset for a foreign recipient who genuinely wishing to understand humour products from a different and remote culture. We wanted to show, and to some extent share, that the cartoons, provided they are not strictly political or crammed with regional issues and accents, could be fathomed by an outsider with the help of a decent translation and an adequate amount of contextual and cultural background information. We have assumed, from the very beginning of this project, that the contemporary Turkish humour, particularly cartoons that are represented in Leman and other similar publications, was interesting enough to become a dissertation subject, particularly those with stock types or characters since they have the potential of becoming snapshots of a country which is still considered as alien (or other) by the West. As far as this writer concerned, the main points of interest concerning Turkey by the British public could roughly be summarised in two points: a bargain trip to the seaside during the summer season and some occasional football matches Manchester United plays against Turkish teams in Istanbul. Especially the latter always attracts heavy press coverage during and after a match. We wanted to show that there are other cultural aspects exist in Turkey as well and such aspects could be transferred to other cultures by ways of translation. The material we have chosen is both visual and prose at the same time and although they function as a unity, they also complement each other. It is proposed that, although a perfect translation is always a desirable concept in almost every field, the translation of humour is possible within certain frameworks. The visual side of cartoons, as in situation comedies, contributes immensely to the comprehension of the message, which should be considered as the most important feature of the joke. To this end, a variety of cartoons are selected from both Lenicyn and other similar humour weeklies and translated with an adequate amount of background and contextual information that provided beforehand. This background information also includes, as far as the material in question permits, a close analysis of the language and the subject matter. To provide a better insight for the reader, a summary of Turkish humour and humour magazines are added alongside a section on the issue of humour itself.

Structural Tools In The Making Of Cities:form As A Development Control MechanismCeylan, Aybike 01 December 2003 (has links) (PDF)
Macro-scale planning and design as a product of modernism have been abandoned to a high degree, as a result of the reactionary post-modern approaches since the 1960& / #65533 / s.
Intensifying with the rise of neo-liberal approaches in the 1970& / #65533 / s, these reactions advocated merely incremental decision-making and design in the making of cities. These developments lived in the western countries showed their reflections in Turkey with the 1980& / #65533 / s, resulting in fragmented planning practices. However it is the hypothesis of the study that macro-scale urban design: thus designing the form and the structural elements of the city is the statement of the
development policy of the city. Thus structural elements that make up a certain city form is a major area of concern for urban design. Within this frame firstly the debate between the modern and post-modern approaches about the scope of intervening in the development of the city will be evaluated. Then the Turkish planning approach will be analyzed with regard to its success in development control. Basic city forms and their growth characteristics will be examined in the next part. Finally the planning practices of Ankara and the form and
the structural elements proposed will be evaluated accordingly.

Origins, Aims And Methods Of Basic Design Courses In Industrial Design Programs In TurkeyDamla, Ozer 01 January 2005 (has links) (PDF)
This study examines basic design courses in industrial design programs in Turkey, in terms of origins, aims and methods. The aim of the study is to inquire the differences and similarities, and to understand factors affecting the characteristics of basic design courses. A field study was conducted about the subject, which comprised of interviews with instructors of basic design courses and chairpersons in six departments offering undergraduate program in industrial design in Turkey.
The field study indicated that the aims of the course in different institutions were similar, whereas the origins, methods and the content varied. Of the factors affecting basic design education, student admission procedure, background of students and the faculty that the industrial design department belonged to were found to be important. The differences among course instructors were also found to be as much significant as the institutional differences.

Craft Culture As The Source Of Inspiration For Industrial Design In TurkeyDemircan, Deger 01 November 2005 (has links) (PDF)
iv
It is widely known that Turkey has a great amount of data of traditions and cultures
on its broad land. By the effects of different dynamics in the 20th century, many
craftsmanship and mastery as parts of traditional culture have been transforming
day by day. Throughout that transformation period, some traditional craft products
could find alternative methods to survive although some others did not.
Craft products have been searched by social anthropology since they are members
of material culture of humankind for a long time. It can be said that most
contemporary objects are transformed versions of older ones in the history.
However, all the products today are continuously transforming by the effects of
different factors. There still are craft objects and craftsmanship in the market.
Traditional craft products, in Turkey, have been transforming by the effects of
technology, change in social conditions and marketing issues and designer&rsquo / s
initiative as well. Industrialization directly has effected craft production to weaken but
some alternative methods are found to provide revival of these professions and
objects.
This study examined transformation in craft objects focusing on the existing scene of
traditional products in Turkish market. Data about craft culture is collected through
observations and interviews with craftsmen considering existing craft products in the
market. Examples of craft objects and objects designed by getting inspired from
craft culture are classified in the chart constituting a schema for the methods for
transformation of craft objects. Dynamic factors affecting the transformation process
of craft objects are discussed. The need for the revival of traditional culture via
design and reasons to do so are explained.
In the thesis, it is claimed that one of the agents of traditional product&rsquo / s
transformation is the designer&rsquo / s attitude. Designer can determine the method for the
transformation of traditional products. So, for the revival of craft culture in the next
generations, the essence of traditional culture behind the traditional products can be
re-used in industrial design. While searching for the convenient methods of
transformation of traditional products, designers&rsquo / opinions about craft culture and reusing
information of culture and tradition in design are searched through a
questionnaire. Possible methods for the revival of craft culture through design are
examined.
