Perde olarak kullanılan dokuma kumaşların seçilmiş dayanım ve estetik performans özelliklerinin araştırılması
Ev tekstili Türkiye'de tekstil üretiminin ve ihracatının en önemli kalemlerinden biridir. Perdelik kumaşlar ev tekstili sektöründe oldukça geniş bir paya sahiptir. Tüketicilerin perdelik kumaşlardan beklentisi hem estetik olarak hoş görünmesi ve kullanım ömrünüm uzun olmasıdır. Bundan dolayı bu kumaşlar için en önemli iki parametre dayanıklılık ve estetik olmasıdır. Perdelik kumaşlardan beklenen en önemli estetik özellik dökümlülüktür. Kumaşların esnekliği ve ağırlığı bu özelliğin kazandırılmasında etkilidir. Bunun yanında buruşmazlık özelliği de perdelik kumaşlar için önem taşır. Ancak, bunların yanında tüketici yüksek dayanım performansı da beklemektedir. Kumaş mukavemeti, kumaşların kullanım sırasında gösterdiği performans ve dayanıklılığının belirlenmesinde önemli bir unsurdur. Bu çalışmada perdelik olarak kullanılan, farklı elyaf tiplerindeki kumaşların dökümlülük, mukavemet ve buruşma özellikleri araştırılmıştır.Home textile is one of the most important items of textile production and export in Turkey. Curtain fabrics have a large share in the home textile industry. The expectation of consumers from curtain fabrics is that they look aesthetically pleasing and have a long service life. Therefore, the two most important parameters for these fabrics are durability and aesthetics. The most important aesthetic feature expected from curtain fabrics is drapeability. The flexibility and weight of fabrics are effective in gaining this feature. In addition, crease racovery propetes is also important for drapability of fabrics. However, besides these, the consumer expects high endurance performance. Fabric strength is an important factor in determining the performance and durability of fabrics during use. In this study, drapability, strength and wrinkling properties of fabrics of different fiber types used as curtains were investigated
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Variations on the Author
“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
We 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
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Alpaka lifinin dokuma ürünlerde kullanılabilirliği
Alpaka lifi tekstil endüstrisinde özellikli bir lif olarak tanımlanır ve lüks lifler içinde sınıflandırılır. Alpaka lifi dokunulduğunda ipeksi, yumuşak ve pürüzsüz olarak hissedilir. Lüks tutumu ve ipeksiliğinden dolayı fiyatı yüksektir. 22 tane doğal rengi vardır ve genellikle yüksek mukavemetlidir. Alpaka lifinin yün lifinden daha yumuşak ve hafif olduğu ve aynı kalınlıktaki life göre daha sıcak tutuğu ileri sürülmektedir. Bu çalışmada, öncelikle literatürlerden alpaka lif özellikleri incelenmiş ve derlenmiştir. Aynı kalınlıktaki alpaka ve yün lifinden, %100 Alpaka, %70 Yün/ %30 Alpaka, %30 Yün/ %70 Alpaka ve %100 Yün iplik üretilmiş ve aynı makine ve kumaş yapısı özelliklerinde dokunmuştur. Ayrıca, lif ve ipliklerin bazı fiziksel özelikleri test edilmiştir. Kumaş tiplerinin, fiziksel ve estetik performans, tutum ve ısıl özellikleri gibi konfor özellikleri karşılaştırılmıştır. Dokuma kumaş içinde alpaka oranının değişiminin kumaş özellikleri üzerindeki etkisi ve alpaka lif özelliklerinin dokuma kumaşa nasıl yansıdığı incelenmiştir. Kumaş testleri sonuçları SPSS istatistik programı yardımıyla analiz edilip değerlendirilmiştir
