The United Nations Environmental Programme (UNEP), defined an aridity index (. AI) by the ratio of the annual precipitation and potential evapotranspiration (PET) totals. In this work, specific humidity was used instead of PET and a new aridity index (. I q) has been defined using the ratio of annual precipitation totals and annual mean specific humidity (. S h). As shown in this study, . S h can be easily computed with very high accuracy (3.569% error rate) with mean temperature, relative humidity and local pressure which are most commonly and widely measured meteorological data. The single point correlation graph of . S h which shows the entrance of aridity through the South Eastern Anatolia Region into Turkey and the distribution of the aridity over Turkey explains the relationship with . S h and aridity. According to the common and different aspects of arid zones found with . AI, . I q and Erinç aridity index (. I m), . I q found to be applicable for monitoring climate change and distribution of arid zones. © 2012 Elsevier B.V.

A forced vibration analysis of functionally graded (FG) nanobeams is considered based on the nonlocal elasticity theory. The solution is obtained by using Navier method for various shear deformation theories. The material properties of the FG nanobeam vary through the thickness direction according to a simple power law. Effects of the nonlocal parameter, different material composition and length-to-thickness ratio of considered element on the vibration and the effect of frequency ratio and different dynamic loading conditions on dimensionless maximum deflection and mode shapes of FG nanobeam are investigated. As a result the dynamic behavior of the FG nanobeam is influenced by the nonlocal effects. The dynamic deflections obtained by the classical (local) theory are smaller than obtained by the nonlocal theory due to the nonlocal effects. © 2013 Elsevier Ltd.

This review article concentrates on the electrochemical biosensor systems with conducting polymers. The area of electro-active polymers confined to different electrode surfaces has attracted great attention. Polymer modified carbon substrate electrodes can be designed through polymer screening to provide tremendous improvements in sensitivity, selectivity, stability and reproducibility of the electrode response to detect a variety of analytes. The electro-active films have been used to entrap different enzymes and/or proteins at the electrode surface, but without obvious loss of their bioactivity for the development of biosensors. Electropolymerization is a well-known technique used to immobilize biomaterials to the modified electrode surface. Polymers might be covalently bonding to enzymes or proteins; therefore, thickness, permeation and charge transport characteristics of the polymeric films can be easily and precisely controlled by modulating the electrochemical parameters for various electrochemical techniques, such as chronoamperometry, chronopotentiometry, cyclic voltammetry, and differential pulse voltammetry. This review article is divided into three main parts as given in the table of contents related to the immobilization process of some important conducting polymers, polypyrrole, polythiophene, poly(3,4-ethylenedioxythiophene), polycarbazole, polyaniline, polyphenol, poly(o-phenylenediamine), polyacetylene, polyfuran and their derivatives. A total of 216 references are cited in this review article. The literature reviewed covers a 7 year period beginning from 2005. © 2013 Elsevier B.V.

Electrochemical impedance spectroscopy (EIS) is an experimental method for characterizing electrochemical systems. This method measures the impedance of the concerned electrochemical system over a range of frequencies, and therefore the frequency response of the system is determined, including the energy storage and dissipation properties. The aim of this article is to review articles focusing on electrochemical impedance spectroscopic studies and equivalent electrical circuits of conducting polymers, such as polypyrrole, polycarbazole, polyaniline, polythiophene and their derivatives, on carbon surfaces. First, the conducting polymers are introduced. Second, the electrochemical impedance spectroscopic method is explained. Third, the results of EIS applications using equivalent electrical circuits for conducting polymers taken from the literature are reviewed. © 2010 Elsevier B.V. All rights reserved.

A new impedimetric biosensor, based on the use of vascular endothelial growth factor receptor-1 (VEGF-R1), was developed for the determination of vascular endothelial growth factor (VEGF). VEGF-R1 was immobilized through covalent coupling with 3-mercaptopropionic acid which formed a self-assembled monolayer on gold electrodes. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy techniques were employed to characterize the immobilization process and to detect VEGF. To successfully construct the biosensor current, experimental parameters were optimized. Kramers-Kronig Transform was performed on the experimental impedance data. The obtained results provided a linear response range from 10 to 70. pg/mL human VEGF. The applicability of the developed biosensor in the determination of VEGF in a spiked artificial human serum sample was experienced, yielding average recovery of 101%, in that order, with an average relative deviation value less than 5%. © 2011 Elsevier B.V.

This study analyzes the connectivity pattern of the default mode network (DMN) in patients with Alzheimer's disease (AD) in comparison with young and elderly controls using the minimum spanning tree (MST). This tree is a tool from graph theory and connects all the nodes of a graph with the minimum cost. The findings revealed that the alterations of the basic structure represented by the MST might provide valuable insights about the physiopathology of the disease. Additionally, by making use of the MST for functionally clustering the DMN, it was shown that the functional subnetworks comprising the DMN differed among the three subject groups. Nonetheless, there were intact prefrontal and temporal networks in elderly controls and AD patients, as well. The analysis shows that although the topologies of the MST characterized by the degree distributions do not differ significantly among the groups, the DMN of the AD patients exhibits a higher segregation, insomuch that posterior cingulate/precuneus and hippocampus/parahippocampus are heavily isolated from rest of the network. We conclude that the MST can be used effectively for analyzing cortical networks. © 2011 Biomedical Engineering Society.

To compare clinical results of biaxial small-incision torsional phacoemulsification and biaxial small-incision longitudinal phacoemulsification. Department of Ophthalmology, School of Medicine, Namik Kemal University, Tekirdag, Turkey. Randomized controlled clinical trial. Eyes with high-density nuclear cataract were assigned to have biaxial longitudinal (microburst mode) or biaxial torsional phacoemulsification. The main outcomes included corrected distance visual acuity (CDVA), central corneal thickness (CCT), central endothelial cell density (ECD), total ultrasound time (UST), cumulative dissipated energy (CDE), percentage total equivalent power in position 3, and balanced salt solution volume. Postoperative follow-up was at 1 day, 1 week, and 1 and 3 months. Each group comprised 35 patients (35 eyes). Three months postoperatively, the mean CDVA for each group was 0.02 logMAR and the mean CCT returned to the preoperative level (P=.589 and P=.554, respectively). During the postoperative follow-up, the percentage of mean endothelial cell loss in both groups was between 35.4% and 39.1%; there was no statistically significant difference between the groups (P>.05). The mean CDE, UST, percentage total equivalent power in position 3, and balanced salt solution volume values were similar in the 2 groups (P>.05). The risk for high endothelial cell loss should be considered when the phacoemulsification of high-density nuclear cataracts is performed using either method.

Human cystic echinococcosis (CE), one of the most widespread helminthic zoonoses, is a chronic disease caused by infection with the larval stage of the tapeworm Echinococcus granulosus. This disease is highly endemic in some southern (Spain and Italy), eastern (Bulgaria and Romania) European countries and associated (Turkey) countries, where it still represents a major health and economic problem. In endemic areas the annual incidence of CE ranges from 1 to 200 per 100,000 inhabitants and 2-3 million cases are globally estimated. Case series and small clinical trials show a mortality rate of 2-4% for CE, but this increases markedly with substandard treatment and care. The diagnosis of human CE is mainly based on imaging techniques and serological confirmation. Clinical decision making is difficult and the natural history of the cyst is still poorly known. CE is chronic, complex and still neglected. For these reasons the main objectives of HERACLES are: Identify by ultrasound screening the population affected by CE in endemic rural areas of CEE countries; Create CEE national registries for surveillance of CE; Establish a representative bio-bank of genetic Egc isolates and blood/serum/plasma samples; Validate new molecular-based POC-LOC kits for immunological surveillance, diagnosis and follow-up; Identify factor/s associated with CE response to therapy or lack thereof through investigation of host-parasite interplay (parasite virulence vs human immunity); Increase drug bioavailability in an in vivo model, decreasing the length of antiparasitic (ABZ based) treatment of CE and synthesize a new enantiomeric drug based on ABZ. The project stakeholders, especially the rural populations in which CE is endemic, as well as SMEs, will be engaged as an integral part of the project. Special events to increase general awareness of CE and training activities for local health care providers will be organized.

Fruit trees and grapevine are propagated vegetatively and are often grafted. As a result they suffer from a high number of pathogens such as viruses and viroids, a number of which are causing severe yield losses and reduce the productive life of the affected plants. As these pathogens cannot be controlled by the application of chemicals, the most efficient way to combat them is the production and commercialization of high quality pathogen-tested propagative material. Nevertheless, this procedure is not simple and both academia and private sectors are working towards its improvement. In this direction was built the herein interdisciplinary proposal which brings together academia and private companies to collaborate through their expertise on the following objectives: 1) to identify new viral and viroid strains or species affecting fruit trees and grapevine, 2) to optimise existing and develop novel detection methods and 3) to improve propagation and sanitation methods for producing high quality (virus-tested) plant material of fruit trees and grapevine. In this project diagnostic tools that are currently used in certification programs will be combined with cutting edge technologies such as NGS and Nanobodies. The project has eight academic partners within the EU and associated countries, three within Third Countries and five non-academic partners. The knowledge obtained will be shared among the partners of the proposal and further disseminated to academic institutions, nurseries and other private sectors. Most importantly training of a new generation of researchers will be done in close contact to the needs of both industrial and academic sectors. In conclusion, the results of this proposal will enrich the knowledge on viruses/viroids associated with different diseases, improve the sensitivity of their detection methods, lead to new detection products and further contribute to the improvement of the disseminated propagative material of fruit trees and grapevine.
