Microsatellites as a powerful tool for identification of olive (Olea europaea L.) planting material in nurseries
Dunja Bandelj, Branka Javornik, 2007, izvirni znanstveni članek

Opis: Microsatellites were applied to confirm the varietal identity of thirteen olive samples from a private nursery. Allelic profiles of samples were compared to genotyped reference varieties from three olive germplasm collections. Genotyping data of two microsatellite loci (ssrOeUA-DCA3 and ssrOeUA-DCA16) allowed discrimination of ten olive samples and the identification of six olive varieties (Koreneiki, Manaki, Tsounati, Kalamon, Ascolana Tenera, Picual). Mislabelling of two olive accessions (Manyanilla de Sevilla, Coratina) was observed and the lack of reference varieties Nostrana Bitontina and Miloelia hindered the identification of two accessions from the nursery. Accessions denominated as Miloelia and Gaiduroelia were of identical genotype. Different allelic profiles of the Frantoio reference variety were observed from two national olive germplasm collections. Microsatellites were found to be a valuable tool for varietal identity confirmation, in nurseries as well as for screening and managing olive germplasm collections.

Experimental verification of an approximate technoque for damage identification in beams using nonlinear regression analysis of bending frequency changes
Elma Ekinovic, Vlatko Doleček, Slavko Dolinšek, Nedim Hodzic, 2010, izvirni znanstveni članek

Opis: This paper presents the experimental verification of an approximate technique for damage identification in beam-like structures, which is based on the use of bending frequency changes and nonlinear regression analysis. The proposed technique was explained in details in [7] so only few necessary steps are recalled here. The identification of damage location and its depth is performed by use of experimentally measured frequency changes and previously established regression relations between bending frequency changes and damage parameters. The experiments were performed on the intact and damaged beams. The damage in these experiments is made by saw cut as a narrow open notch perpendicular to the beam axis. The results of identification are promising taking into account inevitable modelling and measurement errors.

An aproximate technique for damage identification in beams using nonlinear regression analysis of bending frequency changes
Elma Ekinovic, Vlatko Doleček, Slavko Dolinšek, Nedim Hodzic, 2009, izvirni znanstveni članek

Opis: This paper addresses the problem of damage identification in beam-like structures on the base of bending frequency changes. The identification of damage location and its depth is performed by use of regression relations between changes in natural frequencies and damage parameters. Input data for establishing the regression relations are collected using numerical analysis (FEA) of the beam structure with and without damage. The damage is simulated as a narrow open notch perpendicular to the beam axis. The efficiency and limitations of the proposed technique are assessed through a series of damage scenarios.
