In this work, we present some results related to coverings of structured Lie groupoids. Firstly, we obtain a covering Lie group-groupoid and a covering morphism of Lie group-groupoids from a given Lie group-groupoid by the notion of action. Secondly, we show how the Lie group structure of a Lie group-groupoid is lifted to a covering Lie groupoid. Then, we give similar results for Lie ring-groupoid which is also a structured Lie groupoid.
Scleroderma or systemic sclerosis is a complex connective tissue disease which is characterized by vasculopathy, autoimmunity and progressive fibrosis in the skin and visceral organs [1-3]. It includes diffuse and limited subgroups. These groups are separated from each other by skin involvement [4]. Despite some characteristics distinguishing the two types from each other, they share the common feature of fibrosis involving excessive Extracellular Matrix (ECM) production that impairs usual tissue characteristics to cause organ failure late in the disease course [5]. Although a large body of novel scientific knowledge has been acquired about the molecular mechanisms of pathophysiology of SSc [6-8] we are far from stopping or even slowing down the ongoing fibrotic process characterizing the disease [9-11]. In this immunohistochemical study, we aimed to find new markers to predict prognosis and guide therapy.
Ceramics is one of the most important materials that carry the traces of past. Kitchenware, architectural elements and religious forms that are made of ceramics carry the important traces of cultures, which they belong to. In this context, the art of ceramics is a field where symbolic statements exist as a mean of expression and it establishes an organic correlation between past and present. One of the most important of these forms that belongs to this expression is the ‘tree of life’. The form of the tree of life differs stylistically and figuratively from culture to culture and it has great expressional richness. In this study, which was supported by Anadolu University as a scientific research project, the pattern of Metepec, which is the centre of ceramics in Mexico and still continues to produce pottery, and of Turkish art of ceramics were analysed and compared historically, stylistically and technically
To present the results of our cases of Dupuytren's disease treated with regional selective fasciectomy in light of the literature.
Onemli bir meyve zararlisi olan Akdeniz meyve sinegi, Ceratitis capitata (Wiedemann, 1824) (Diptera, Tephritidae)’nin yayilis alanini mevcut iklimsel kosullar altinda genisletmeyecegi dusunulmekte; ancak, C. capitata istilasi icin uygun gorunen Karadeniz kiyilarinin bu genellemenin disinda oldugu varsayilmaktadir. Bati Karadeniz Bolgesi’nde C. capitata ile enfekte olmus bir mandalina bulunduktan sonra bu varsayim sinanmistir. Oncelikle Turkiye’de C. capitata ’nin yasamasina uygun olan alanlarin tespiti icin ekolojik nis modellemesi yaklasimi kullanilmis, daha sonra da modelin uygun olarak tahmin ettigi Dogu Karadeniz Bolgesi’nde arazi calismalari yapilmistir. Modelleme icin C. capitata ’nin varligi bilinen Akdeniz ve Ege Bolgesi’nden 49 noktadan ve C. capitata ’nin varligi bilinmeyen Karadeniz Bolgesi’nden bir noktadan 2014 ve 2015 yillari Kasim ayinda meyve ornegi toplanmis ve laboratuvara getirilerek ergin cikislari izlenmistir. Toplamda 44 farkli yoreden ergin C. capitata elde edilmistir. Bu noktalar model icin veri olarak kullanilmistir. Modelleme sonuclarina gore Karadeniz Bolgesi’nde arazi calismalari gerceklestirilmistir. Meyve ornekleri 11 noktadan toplanarak laboratuvara getirilmis ve ergin cikislari izlenmistir. Bu orneklerden toplam 49 ergin C. capitata cikmistir. Boylece Dogu Karadeniz’de Akdeniz meyve sineginin ilk kez varligi gosterilmistir. Model ayrica gelecekte Karadeniz havzasinda C. capitata icin uygun olan alanlarin olusacagini da gostermektedir.
Bazi sabit nokta yineleme yontemlerinin, belirli bir buzulme sartini saglayan operatorlerin sinifindan secilen elemanlarin karakterlerine bagli olarak farkli yakinsama davranislari sergiledikleri numerik bir ornek verilerek gosterilecektir.
