In this study, current infrageneric taxonomic status of Limonium Mill. in Turkey was assessed by using numerical taxonomy (phenetics) method. Herbarium materials belong to 21 species of Limonium Mill., collected all around Turkey, and were examined. In order to evaluate the infrageneric status, 52 characters based on ecological and morphological features of the genus were determined and recorded to construct a data matrix which was analyzed by MultiVariate Statistical Package (MVSP) and Statistica software with Unweighted Pair Group Method with Arithmetic Mean (UPGMA) method to construct phenograms. Then, by assesing the phenograms, an overall comparison of Limonium Mill. species were made and infrageneric taxonomic status of the genus was discussed. The result of this study indicated that 5 sections of the genus are represented in phenograms which was a compatible result with theoretical information written in 7th Volume of “Flora of Turkey”. Moreover, in UPGMA trees, a new section (belonging Section Limonium) is observed. Section nova species live only near seashore and distinctively separated from other Section Limonium species in phenograms and Principle Component Analysis (PCA). PCA was carried out to indicate most important characters used in this study. In addition, in this study, a dichotomous key comprising all the species of Limonium Mill. in Turkey was also presented. In appendix part, brief information about each species such as distribution, habitat, conservation status, habit, endemism ratio, flowering period, IUCN categories was given to review all Limonium Mill. species in Turkey.

Investigation of chemopreventive and apoptotic characteristics of turkish medicinal plant rheum ribes Uyar, Pembegül; Çoruh, Nursen; İşcan, Mesude; Department of Biotechnology (2011) Rheum species are medicinally important plants due to the presence of anthracene derivatives and in this study antioxidative, cytotoxic, apoptotic and chemopreventive characteristics of R. ribes extracts were evaluated. R. ribes shoot and root dry powder samples were prepared and extracted with ethyl acetate, ethanol and water. The extracts were revealed to be a potential scavenger of DPPH radicals and the chemical composition of the extracts was quantified by colorimetric determination of total phenol (GAE...
A numerical taxonomic study of the genus Acantholimon Boiss Plumbaginaceae in Ankara Province Turkey MUVAFFAK, Aslı; Doğan, Musa; Bilgin, Cemal Can (Laser Pages Publishing Ltd., 2001-01-01) This study examines whether a satisfactory classification of Acantholimon Boiss. (Plumbaginaceae) species found in Ankara province (Turkey) can be obtained from phenctic clustering based on external vegetative and floral morphological characters of both herbarium and collected specimens, The study is on the following species: A. venustum Boiss., A, halophilium Bokhari., A. acerosum (Willd.) Boiss., A. kotschyi (Jaub. & Spach) Boiss., A. confertiflorum Bokhari., A. glumaceum (Jaub. & Spach) Boiss., A. casare...
A Prostate Cancer Model Build by a Novel SVM-ID3 Hybrid Feature Selection Method Using Both Genotyping and Phenotype Data from dbGaP Yucebas, Sait Can; Aydın Son, Yeşim (2014-03-20) Through Genome Wide Association Studies (GWAS) many Single Nucleotide Polymorphism (SNP)-complex disease relations can be investigated. The output of GWAS can be high in amount and high dimensional, also relations between SNPs, phenotypes and diseases are most likely to be nonlinear. In order to handle high volume-high dimensional data and to be able to find the nonlinear relations we have utilized data mining approaches and a hybrid feature selection model of support vector machine and decision tree has be...
Investigation of the cracking of CFRD face plates Arıcı, Yalın (Elsevier BV, 2011-11-01) The primary goal of this study was to examine the cracking behavior of the face plate of a CFRD over its life cycle. Analyses of the construction stage, impounding, long-term deformation and earthquake loading were conducted in sequential phases using a 2-D plane-strain model with the appropriate nonlinear constitutive relationships for the dam constituents. The state of stress and the cracking behavior of the plate were found to be substantially different in the short and long term. Earthquake loading appe...
Discovering functional interaction patterns in protein-protein interaction networks Turanalp, Mehmet E.; Can, Tolga (Springer Science and Business Media LLC, 2008-06-11) Background: In recent years, a considerable amount of research effort has been directed to the analysis of biological networks with the availability of genome-scale networks of genes and/or proteins of an increasing number of organisms. A protein-protein interaction (PPI) network is a particular biological network which represents physical interactions between pairs of proteins of an organism. Major research on PPI networks has focused on understanding the topological organization of PPI networks, evolution...
