Using Biophilic Design Principles Indoor to Increase the Competence of Users That Have to Work From Home During the Pandemic
No full text▪ Yüksek lisans tezi.Koronavirüs olarak adlandırılan Covid-19 pandemisi 2019 yılından itibaren hayatımızda yer almaktadır. Virüsün yayılma ve bulaşma riskini azaltmak adına ülkeler sınırlarını kapatmış, seyahat kısıtlaması, sokağa çıkma yasağı, eğitime ara verilmesi, karantina gibi önlemler almıştır. Bu nedenle de, insanlar çeşitli değişikliklere maruz kalmıştır, yaşadıkları konutlarda tasarım olarak bir dizi değişiklikler yapma kararı almış, evden çalışmak zorunda kalan kullanıcılar ise çalışma alanlarını daha kullanışlı hale getirme ihtiyacı duymuştur. Bu sebeple, konutlarda ofis kavramı değişmiş, kullanıcılar daha verimli ortamlar için değişik tasarım fikirlerine ihtiyaç duymuştur. Ancak, salgın döneminde kullanılan malzemelerin doğal olması, tasarımda kullanılan renkler, konuttaki oksijen miktarı vb düşünülerek doğa ile iç içe tasarım anlayışı benimsenmiş ve biyofilik tasarımın kullanılmasına önem verilmiştir. Biyofilik tasarım pandemi döneminde daha fazla önem kazanmıştır, çünkü evde kapalı kalınan süreçlerde insanlar doğadan uzaklaşmıştır. Bu tezde doğadan uzaklaşmamak, tam tersine biyofilik tasarımla çalışma kapasitelerinin artırılabilecek mekanların tasarlanmasına yönelik öneriler yapılması hedeflenmiştir. Bunu yapabilmek için de biyofilik tasarımla yapılmış var olan ofislerin incelenmesi, buradan çıkarılacak tespitler sonucunda yeni bir tasarım önerisi geliştirilmesi hedeflenmiştir. Bu tasarım önerisiyle, pandemi sürecinde veya buna benzer karantina döneminde home office'te çalışmak zorunda kalan kullanıcıların bu süre içerisindeki verimliliklerini artırabilmeleri hedeflenmiştir. Ancak, bu önerinin tam anlamıyla uygulanabilmesi için pilot bir bölge seçilerek bir tasarım uygulaması yapılması uygun olacaktır
European Public Opinion on Turkey’s EU Accession
Full text linkThe study evaluates enlargement more than a technical procedure that takes public opinion into account as well. According to the findings of the research, public support for Turkey’s accession to the EU is not only low, but also in decline. With some exceptions, the ‘new’ (EU-28) are generally more favorable towards Turkey’s accession while the ‘old’ (EU-15) oppose it.1 EU countries with a large Turkish population are generally against to welcome Turkey in E
Pyrolysis-Free Mechanochemical Synthesis of Cobalt Polyphthalocyanine Electrocatalyst for Enhanced Oxygen Reduction Reaction
No full textThe urgent need to battle the rising global temperatures caused by human-induced activities, primarily fossil fuel usage, highlights the importance of switching to renewable energy sources such as solar and wind power. Fuel cells are viable for sustainable energy generation since they efficiently convert chemical energy into electricity with minimal losses. However, the usefulness of these devices is limited by the slowness of oxygen reduction (ORR) - processes at the cathode of the fuel cell, which leads to the search for better electrocatalysts to increase efficiency. In this context, metal-nitrogen-doped carbon (M-N-C) catalysts provide a convincing alternative to noble metals in ORR. However, hurdles must still be overcome to increase their activity and manage active site distribution. Traditional synthesis processes are both ecologically damaging and economically inefficient, driving the development of greener alternatives such as mechanochemistry. In this thesis, a novel pyrolysis-free mechanochemical method is developed to synthesise cobalt polyphthalocyanine (Co-PPc) electrocatalyst. This research contributes to the synthesis of efficient, cost-competitive, and environmentally friendly electrocatalysts for sustainable energy storage and conversion applications
EU Policy towards Eastern Partnership Countries. A Gap between Goals and Achievements
Full text linkThis study seeks to examine and assess the effectiveness of the Eastern Partnership Policy (EaP) of the European Union. Beside introduction of positive novelties of the Eastern Partnership, this paper gives a premium attention to scrutinize the possible limitations and shortfalls of EaP. Hence, the study aims to analyze some internal and external factors that complicate the effective functioning of the EaP. The inconsistency of the EU policy structure, the role of Russia and its Eurasian Economic Union (EaEU) in EAP, the ambivalent policy of some Member States (Germany and Italy are examined) toward the EaP, unconsidered discrepancy of eastern partners are analyzed and considered as prime reasons of ineffectiveness. In addition, examined case studies of Ukraine and Azerbaijan reveal that the EU's commitment to their "shared values" are controversial. This paper presents that the EU should find a balance between its economic/energy interests and normative values vis-a-vis Eastern Partners in order to fill the gap between its goals and achievements
Влияние раздоров в руководстве Азербайджанской Советской Социалистической Республики в 1920-х годах и их влияние на политико-экономическую жизнь страны
Full text linkThis article studies the disagreements in the leadership of the Azerbaijan SSR in the 1920s and the effect of these contradictions on the political and economic life of the republic. The research material is historical documents and historical and theoretical literature. The research topic is relevant, as it provides undeniable historical facts about the territorial integrity of Azerbaijan. For the first time, the article analyzes the historical events of those times from the point of view of modern historical events they are interconnected with. It also examines the status of the Azerbaijani language in such a difficult historical period. In the course of the research, the historical-descriptive method and the method of historical analysis were used. As a result of the study, it was revealed that in 1920 intra-government disagreements and disputes began with the creation of the Soviet government between nationalist-minded forces and the Bolshevik forces of Armenian origin emissaries of Moscow. This strife ended in the defeat of the Azerbaijani national communists due to the unequal distribution of forces. Thus, the Central Bolshevik government and its Baku emissaries of non-Azerbaijani origin removed the obstacles that contradicted their policy in Azerbaijan and began to implement in full force the chauvinist national policy under the veil of international philosophy. Summing up, the author points out the causes of strife and disagreement among the authorities of Azerbaijan in the 1920s. He notes that these reasons were negligence and disrespect for sovereignty and territorial integrity, wealth, language, religion and national traditions, peasants and intellectuals of Azerbaijan. This attitude was also observed in the field of economic issues. This study's presented materials and conclusions can be useful for historians and further research in this direction.Данная статья рассматривает разногласия в руководстве Азербайджанской ССР в 1920-х годах и влияние данных противоречий на политическую и экономическую жизнь республики. Материалом исследования являются исторические документы и историко-теоретическая литература. Тема исследования актуально тем, что здесь предоставляются неоспоримое исторические факты о территориальной целостности Азербайджана. В статье впервые анализируются исторические события тех времен с точки зрения современных исторических событий, с которыми они взаимосвязаны. Здесь также рассматривается статус Азербайджанского языка в столь сложном историческом периоде. В ходе исследования были использованы историко-описательный метод и метод исторического анализа. В результате исследования было выявлено, что в 1920-м году внутри-правительственные разногласия и споры начавшиеся с созданием советского правительства происходили между националистически настроенными силами и большевистскими силами армянского происхождения, выступающими в роли эмиссаров Москвы. Эти раздоры завершились поражением Азербайджанских национальных коммунистов по причине неравного распределения сил. Таким образом, Центральное большевистское правительство и его Бакинские эмиссары неазербайджанского происхождения устранили препятствия, противоречащие их политике в Азербайджане, и начали в полную силу притворять в жизнь шовинистическую национальную политику под вуалью интернациональной философии. Подводя итоги, автор указывает причины раздоров и разногласий среди властей Азербайджана в 1920-х годах. Он отмечает, что этими причинами являлись небрежность и непочтительное отношение к суверенитету и территориальной целостности, богатству, языку, религии и национальным традициям, крестьянам и интеллигенции Азербайджана. Такое отношение также наблюдалось в сфере экономических вопросов. Изложенные материалы и выводи данного исследования могут быть полезны для историков и исследований в данном направлении
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
An Investigation on the Suitability of Abrasive Waterjet Cutting for Hybrid Manufacturing of Gears in Automotive Industry
No full textGears are components in mechanical assemblies used for transmitting power and motion. Gear form cutting (broaching, milling) and gear generating (shaping and hobbing) are two of the main gear manufacturing methods. Usually production involves three stages: (i) soft machining, (ii) heat treatment, and (iii) hard machining. Limitations introduced by conventional methods can be listed as follows: - In machining difficult to cut materials, high cost of specialized cutting tools, high cutting tool failures is a major issue and high cost of machine tools. - Stresses generated due to heat (thermal stresses) and cutting force affect the component life and cost. This demands alternative ways of material removal without affecting the mechanical properties while delivering right quality in a cost effective way which is the goal of the industry. - Increasing standards on environmental impacts associated with products force the modern manufacturing industry to take critical approach on making processes environmental friendly. Large volume of material is removed during conventional gear production resulting in higher lead time, more use of cutting fluids (and its disposal), chip handling (and its disposal) and dust. In this context, abrasive waterjet (AWJ) cutting is considered to be a good addition to the current production system due to the low amount of applied force, negligible heat generated during machining, minimal change in material properties, versatility, lower initial investment and environmental friendliness (no chip generation and no need for cutting fluids). To demonstrate the capability of the proposed approach in manufacturing spur gears and helical gears, forged gear blanks typically used on automobile industry were used for initial tests and two gears were produced using 3-axis KimTech and 5-axis FineCut precision AWJ machine tools. Individual teeth have been separated from each gear and tested against each other from different perspectives. The metrological, surface integrity, productivity and production cost comparisons were presented.While improvements were achieved from environment and surface integrity perspectives, AWJ cutting cannot replace soft machining stage due to increased lead time and production cost. Novel hybrid gear manufacturing method was proposed from the experiences from this research and compared against the conventional method employed in the automotive industry. Proposed hybrid approach comprises AWJ cutting process as the major material removal method and conventional 5-axis machining for final finishing or maintenance of tight tolerances and at the same time, decreasing initial investment and adding further flexibility to production system.This publication is part of my research work at KTH Royal Institute of Technology, thanks to a Swedish Institute scholarship
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
