The first helminth study on Brandt's Persian Lizard Iranolacerta brandtii (De Filippi, 1863) (Squamata: Lacertidae) from Van Province, Turkey

Population of Iranolacerta brandtii lizard including 56 (21 female, 34 male,1 juvenile) samples were examined for helminths. 17 of them were found to harbour one or more helminth parasites, while 39 didn't harbor any. Two helminth species were determined. These belong to Phylum: Nematoda, Spauligodon aloisei Casanova, Milazzo, Ribas & Cagnin, 2003 and Skrjabinodon medinae. Garcia-Calvente, 1948. This study represents new host and locality records in both host lizard and the helminth species. Sp. aloisei is recorded for the first time; Sk. medinae is the third report from Turkey nevertheless Sk. medinae is a new host record for I. brandtii

DEVELOPMENT OF THE NEW TEST CHAMBER FOR THE CALIBRATION OF THE HYGROMETERS

Ölçüm cihazlarının kalibrasyonunun düzenli olarak yapılması bir zorunluluktur. Kalibrasyon, belirlenen koşullardaki değerlerle, ölçme sisteminin veya ölçme cihazının gösterdiği değerler arasındaki ilişkiyi belirleyen işlemler dizisidir. Bu çalışmada; bir seri sıcaklık ve nemin gözlenmesiyle, nem ölçerlerin kalibrasyonunun yapılması için özel bir düzenek hazırlandı. İzole bir kabin içerisinde %15 ile %95 aralığında bağıl nem değerleri sağlandı. Düzenekte, sistemin kararlı hale gelebilmesi için kurutma ve egzoz sistemi tasarlanıp, tüm işlemler elektronik olarak kumanda edilerek, sensörler yardımıyla da bilgisayar üzerinden izlendi. Sistem kararlı hale geldikten sonra, önceden kabin içine yerleştirilmiş olan kalibrasyonu yapılacak nem ölçerin ölçüm sonuçlarıyla, psikrometrenin (referans ölçüm cihazı) ölçüm sonuçları karşılaştırıldı. The calibration of the measuring instruments must be done periodically. Calibration is the set of operations, the relationship between values of quantities indicated by a measuring instrument or measuring system represented by a reference material and the corresponding values realized by standards. In this work, the humidity and temperature is observed and the special apparatus is prepared for the calibration of the humidity measurements. In the test chamber the relative humidity is taken in between % 15 and % 95. In apparatus, the drying and eject system is planned for the steady-state system and all process are commanded electronically and are displayed, followed by sensors on the computer. After system becomes steady state, the results of humidity measurement installed in the test chamber are compared with the results of psycrometer

Helminth fauna of Lebanon lizard, Phoenicolacerta laevis (Gray, 1838), (Squamata: Lacertidae) from Southern Turkey

In the years 2010 and 2014, fifty-four samples of Phoenicolacerta laevis from eight localities in Adana (n=6) and Hatay (n=48) were collected and examined for helminth parasites. New host and locality records were recorded. As a results of present study, three species of Digenea, Sonsinotrema tacapense, Prosthodendrium chilostomum, Brachylaima sp. (metacercaria); two species of Cestoda, Oochoristica tuberculata and Mesocestoides sp. and four species of Nematoda, Skrjabinodon medinae, Spauligodon sp., Thubunaea sp. and a larva of the Ascaridiidae Ascarididae gen. sp. were reported for lizard samples. We document new host records for all of helminth species reported here. Sonsionotrema tacapense (Digenea), and Thubunaea sp. (Nematoda) are recorded for the first time from Turkey. There are, to our knowledge, no reports of helminths for P. laevis in Turkey and also from its range

A skeletochronological study of parthenogenetic lizards of genus Darevskia from Turkey

The skeletochronological method has been used to assess age distribution and age-related differences in body size among populations of the parthenogenetic lizards Darevskia sapphirina, D. uzzelli, D. armeniaca and D. unisexualis from Turkey and Armenia. The age distribution between D. armeniaca and D. unisexualis did not significantly differ and ranged from 1 to 8 years. Maximum age for both D. uzzelli and D. sapphirina was 6 years, and 8 years for both D. unisexualis and D. armeniaca. In all the studied species, individuals reached sexual maturity after third hibernation. According to patterns of growth marks resorption, D. sapphirina is distinguished from all other rock lizards of genus Darevskia by a narrowest periosteal bone as result of high rate of endosteal resorption resulting in complete destruction of hatchling line and line of the first hibernation

Thermal Conductivity of Carbon Nanotubes and their Polymer Nanocomposites: A Review

Thermally conductive polymer composites offer new possibilities for replacing metal parts in several applications, including power electronics, electric motors and generators, heat exchangers, etc., thanks to the polymer advantages such as light weight, corrosion resistance and ease of processing. Current interest to improve the thermal conductivity of polymers is focused on the selective addition of nanofillers with high thermal conductivity. Unusually high thermal conductivity makes carbon nanotube (CNT) the best promising candidate material for thermally conductive composites. However, the thermal conductivities of polymer/CNT nanocomposites are relatively low compared with expectations from the intrinsic thermal conductivity of CNTs. The challenge primarily comes from the large interfacial thermal resistance between the CNT and the surrounding polymer matrix, which hinders the transfer of phonon dominating heat conduction in polymer and CNT. This article reviews the status of worldwide research in the thermal conductivity of CNTs and their polymer nanocomposites. The dependence of thermal conductivity of nanotubes on the atomic structure, the tube size, the morphology, the defect and the purification is reviewed. The roles of particle/polymer and particle/particle interfaces on the thermal conductivity of polymer/CNT nanocomposites are discussed in detail, as well as the relationship between the thermal conductivity and the micro- and nano-structure of the composite
