Type B plactic relations for rr-domino tableaux

The recent work of Bonnafé et al. (2007) shows through two conjectures that $r$-domino tableaux have an important role in Kazhdan-Lusztig theory of type $B$ with unequal parameters. In this paper we provide plactic relations on signed permutations which determine whether given two signed permutations have the same insertion $r$-domino tableaux in Garfinkle's algorithm (1990). Moreover, we show that a particular extension of these relations can describe Garfinkle's equivalence relation on $r$-domino tableaux which is given through the notion of open cycles. With these results we enunciate the conjectures of Bonnafé et al. and provide necessary tool for their proofs

Lower and Upper Bounds for Nonzero Littlewood-Richardson Coefficients

Given a skew diagram $\gamma/\lambda$, we determine a set of lower and upper bounds that a partition $\mu$ must satisfy for Littlewood-Richards coefficients $c^{\gamma}_{\lambda,\mu}>0$. Our algorithm depends on the characterization of $c^{\gamma}_{\lambda,\mu}$ as the number of Littlewood-Richardson tableau of shape $\gamma/\lambda$ and content $\mu$ and uses the (generalized) dominance order on partitions as the main ingredient

Scopus Dergi Seçim Kriterleri Üzerine Bir Değerlendirme

Scopus uses some criteria to decide which journals to index in the database. This paper evaluates the journals indexed in Scopus database according to these criteria. The study universe consisted of 2013 Scopus journal list downloaded from SCImago Journal Rank (SJR) web page on September 18th, 2014. Countries that have more than 1000 journals and less than 100 journals in Scopus were left out of the study. The 203 journals were selected from 6,151 journals by the systematic sampling method and of these, 203 journals were analyzed with regard to the Scopus journal selection criteria. Based on the analysis of findings, we found that the most problematic criteria were having an online referee list, having publication ethics, citation levels of journals and internationalization. On the other side, regular publishing, having English journal website, having English titles and abstracts and having references in Roman Script were the most successful criteria. Scopus, veri tabanında dizinleyeceği dergilere karar vermek amacıyla birtakım kriterler kullanmaktadır. Bu makale, Scopus veri tabanında dizinlenen dergileri söz konusu kriterler doğrultusunda değerlendirmektedir. Çalışmanın evrenini SCImago Dergi Sıralaması (SJR) web sayfasından 18 Eylül 2014 tarihinde indirilmiş olan 2013 yılı Scopus dergi listesi oluşturmaktadır. Scopus’taki dergi sayıları 1000’den fazla ve 100’den az olan ülkeler çalışmaya dahil edilmemiştir. Sistematik örneklem seçme yöntemi ile 6151 dergi içinden 203 dergi seçilmiş ve bu 203 dergi Scopus’un dergi seçim kriterleri dikkate alınarak analiz edilmiştir. Analiz sonucundaki bulgulara dayanarak en problemli kriterlerin web sitesi aracılığıyla erişilebilen hakem listesine sahip olma, yayın etik ilkelerine sahip olma, dergilerin atıf düzeyleri ve uluslararasılaşma olduğu bulunmuştur. Diğer yandan derginin düzenli yayımlanması, İngilizce web sayfasının olması, dergi makalelerinin İngilizce başlık ve özlerinin olması ve kaynakçanın Latin harfleri ile verilmesi kriterleri bakımından başarı düzeyinin en yüksek düzeyde olduğu görülmüştür.

Fabrication, characterization and fibroblast proliferative activity of electrospun Achillea lycaonica-loaded nanofibrous mats

Şahin, Yeşim Müge (Arel Author)The use of natural compounds such as biocompatible and non-toxic plant extracts, without undesired side effects, in tissue engineering applications, is highly preferred compared to chemical drugs. In this study, the characterization and performance of electrospun Achillea lycaonica-loaded (0.125, 0.250 and 0.500, wt%) poly(lactic acid) (PLA) (8%, w/v) nanofibrous mats for skin tissue engineering were investigated. SEM, FTIR, DSC, and tensile strength test of the electrospun nanofibers have been investigated. Drug releasing test and cell culture study were also carried out. Achillea lycaonica-loaded nanofibrous mats in 0.250 (wt%) and 0.500 (wt%) demonstrated excellent cell compatibility and increased the viability of NIH/3T3 (mouse embryo fibroblast) cells within 72 h. According to the results, Achillea lycaonica-loaded PLA nanofibers have proper tensile strength and controlled release. The working temperature range enlarged for the composites having higher plant extract content. Consequently, Achillea lycaonica-loaded nanofibrous mats have a great potential in skin tissue engineering applications. © 2019 Elsevier LtdDr. Muhammet E.
