New Records Of Psilophrys Parvulus And Its Host Kermes Bacciformis From Turkey, George Japoshvili, Mehmet Bora Kaydan, İsmai̇l Karaca
Turkish Journal of Zoology
During 2007-2008 survey conducted on the Turkey oak (Quercus cerris) in Isparta province Psilophrys parvulus (Hymenoptera: Chalcidoidea, Encyrtidae) and its host Kermes bacciformis (Hemiptera: Coccoidea, Kermesidae) represent new species records for Turkey. Previously, P. parvulus was known only from Italy where it was first recorded. The emergence behavior of this parasitoid differs from that of most scale insect parasitoids emerging from the anal opening of its host rather than chewing a hole in the scale insect's test to emerge.

Softcomputing Identification Techniques Of Asynchronous Machine Parameters: Evolutionary Strategy And Chemotaxis Algorithm, Nouri Benaïdja
Turkish Journal of Electrical Engineering and Computer Sciences
Softcomputing techniques are receiving attention as optimisation techniques for many industrial applications. Although these techniques eliminate the need for derivatives computation, they require much work to adjust their parameters at the stage of research and development. Issues such as speed, stability, and parameters convergence remain much to be investigated. This paper discusses the application of the method of reference model to determine parameters of asynchronous machines using two optimisation techniques. Softcomputing techniques used in this paper are evolutionary strategy and the chemotaxis algorithm. Identification results using the two techniques are presented and compared with respect to the conventional simplex technique …

Pca Based Protection Algorithm For Transformer Internal Faults, Erdal Kiliç, Okan Özgönenel, Ömer Usta, Dave Thomas
Turkish Journal of Electrical Engineering and Computer Sciences
In this paper a new protection scheme is introduced to detect and identify transformer winding faults. The new approach is based on artificial neural networks (ANNs) using radial basis functions (RBFs) and the principal component analysis (PCA). The nonlinear system's input and output data is manipulated without considering any model of the system. This approach is used to detect and identify internal short circuit faults of a three phase custom built transformer. The suggested technique is also able to distinguish between the fault and magnetizing inrush current. The test studies carried out shows that the proposed method leads to satisfactory …

Turkish Journal of Medical Sciences
Immunosuppression facilitates varicella zoster virus (VZV) reactivation in immunocompromised patients. Atypical presentation such as disseminated disease of herpes zoster infection has been described in immunosuppressed patients. One of the best choices of therapy in herpes zoster infection is acyclovir, but long-term therapy may cause resistance to it. In this report a disseminated herpes zoster infection is described in a patient with T cell lymphoma after acyclovir/valacyclovir therapy. The infection was irresponsive to acyclovir and valacyclovir and we were unable to control the infection because it was not possible to obtain foscarnet and the patient died due to Staphylococcus epidermis sepsis.

Multivariate Morphometric Study On Apis Florea Distributed In Iran, Ayça Özkan, Mohammed M. Gharleko, Berna Özden, İrfan Kandemi̇r
Turkish Journal of Zoology
Multivariate Morphometric and Spatial Autocorrelation Analyses were performed to determine the morphometric variation in Apis florea colonies representing 13 localities from 4 states on the coastal north-south diagonal in Iran. New morphometric characters (hind wing length, hind wing width, and hind wing angles) were also measured to determine the usefulness of these characters for Apis florea. Analysis of variance of new morphometric characters showed that 7 out of the 8 hind wing variables displayed statistically significant differences among populations (P < 0.05). The scatter plot from Canonical Variate Analysis revealed that the colonies from north (Ilam, Khuzestan, and Bushehr states) showed an overlapping distribution. The colonies from south (Hormuzgan state) formed a non-overlapping distant cluster. Based on the spatial autocorrelation analysis, 14 correlograms were significant for morphometric characters (According to the Bonferroni criterion). Six characters (CuB, C.Ind, HWW, B4, D7, and I13) showed clinal type correlogram.
