Natural epidemics and outbreaks of emerging viral epidemics are growing problems internationally. The general aim of the CCHFVaccine project is to develop and deliver a vaccine, which can significantly increase our capacity to control the situation of Crimean Congo Haemorrhagic fever (CCHF) disease on a global basis. The proposed work program on CCHF virus aims to build a multidisciplinary research network, able to deliver vaccine candidates, methods and procedures eligible for clinical trials, with a special focus on prevention. Thanks to the background, unique facilities and tools available among the consortium participants, CCHFVaccine will deliver tools for countering the threat of this infection in Europe and endemic areas of the world. This work program will attempt to fill gaps in CCHFV virus research on immunology and vaccinology. To achieve this overall aim, an intensive work plan will be put in place with the following specific objectives: i) to produce vaccine candidates, ii) to bring several unique animal models into front line vaccine research, iii) to validate and bring the most promising vaccine candidates to clinical trials, iv) to ensure that an immune mediated protection is adequately understood, v) to perform clinical trials at Phase I and ensure a strategy for the effective deployment and utilization in resource-poor countries, and vi) to link this project to public health bodies, NGOs and vaccine companies. The proposed CCHFVaccine project will succeed in bringing together selected competitive advantages such as: operating capacity with appropriate facilities (state-of-the-art BSL-4s) and the only animal BSL-4 -with capacity to challenge domestic animals in Europe, highly experienced researchers in the development and evaluation of vaccine candidates, authorities and entities of human and animal health, clinical samples from endemic countries, and an international network proven to be functional by the previous EU-funded CCHFever and EDENext.

The interest in alternative or renewable energy sources for greenhouse heating is currently high, owing to the large heating loads and the relatively high price of fossil fuels. Important alternative sources of energy are solar collectors, heat pumps, biomass and cogeneration systems. This study experimentally investigates greenhouse heating by biogas, solar and ground energy in Elazig, Turkey climate conditions. The greenhouse (6 m × 4 m × 2.10 m) heated by mentioned alternative energy sources was constructed, and then required heating load of the greenhouse was determined. For this purpose, biogas, solar and a ground source heat pump greenhouse heating system (BSGSHPGHS) with horizontal slinky ground heat exchanger was designed and set up. Experiments were conducted extensively during the winter period from November 2009 to March 2010. During the experiments, 2231.83 l of gas production by biogas system is provided. The experiments that are required for the growth of many plants need temperature of 23 C, and conceivable success has been achieved in reaching this value by built systems. As a result, different energy sources have been successfully tested for greenhouse heating. © 2013 Elsevier B.V. All rights reserved.

Poly(hydroxyethylmethacrylate-pumice), [P(HEMA-Pum)], composite was synthesized by free radical polymerization in aqueous solution. The adsorptive features of P(HEMA-Pum) composite were investigated for UO22+ and Th4+ using a range of pH, concentration, time (kinetics), temperature (thermodynamics), ionic strength and selectivity, and the related parameters were derived from the obtained results. These results indicated that all adsorbents had high affinity to the uranium and thorium ions. The parameters obtained from Langmuir, Freundlich and Dubinin-Radsushkevich models fit the data well. The values of enthalpy and entropy changes showed that the overall adsorption process was endothermic (ΔH > 0) and increasing entropy (ΔS > 0), and it was spontaneous (ΔG < 0) as expected. The adsorption kinetics following the pseudo-second order model indicated that the rate-controlling step was chemical adsorption that occurred by ion exchange process. Reusability of P(HEMA-Pum) was also investigated, and it was found that the composite could be used at least 5 times. © 2012 Elsevier Ltd.

This paper presents a novel effective method for the optimization of oil agglomeration process of Zonguldak/Turkey bituminous coal with multiple performance characteristics based on the grey relational analysis (GRA). Oil agglomeration parameters including solid content, amount of oil, agitation time and agitation rate were optimized based on multiple performance characteristics. The characteristics of interest are the grade and the recovery of the agglomerates. Nine experiments were conducted using GRA to optimize the settings for oil agglomeration parameters to generate various quality characteristics. Analysis of the grey relational grade indicates the parameter significance and the optimal parameter combination for the oil agglomeration process. The analytical results from two confirmation experiments using the optimal parameters confirm that the above performance characteristics in oil agglomeration process can be improved effectively through this approach. © 2013 Elsevier Ltd.

In this research, a novel composite, poly(acrylamide-expanded perlite) [P(AAm-EP)], was synthesized and its adsorptive features were investigated for UO2 2+ and Th4+ ions. The composite's adsorptive features were evaluated for UO2 2+ and Th4+ ions in light of the dependency of the ion concentration, pH, temperature, time, and reusability. The composite could bind UO2 2+ and Th4+ ions with strong chemical affinity. The correlation coefficients indicate that the Langmuir model fits better for the UO2 2+ and Th4+ onto P(AAm-EP) composite with adsorption capacities as 0.66 and 0.74molkg-1, respectively. Adsorption equilibrium of UO2 2+ and Th4+ ions was achieved in about 34 and 32min, respectively. The kinetic data conformed better to the pseudo-second order equation. The adsorption of UO2 2+ and Th4+ ions increased with increasing pH and reached a plateau value at around pH3.0. Thermodynamic parameters δH and δS values showed that the sorption process was spontaneous (δG<0), endothermic (δH>0), and had increased entropy (δS>0). It was also found that the adsorption kinetics followed the pseudo-second-order model and that the rate-controlling step was chemical adsorption. The reusability of the composites was confirmed for 5 sequential reuses. © 2012 Elsevier B.V.

Recently, Weston et al. (2004; Wide faces or large canines? The attractive versus the aggressive primate. Proceedings of the Royal Society of London, Series B, 271, 416-419) found that facial width-to-height ratio (WHR) is a sexually dimorphic characteristic in humans; males have higher facial WHR than females. Following this study, Carré et al. (2008; In your face: facial metrics predict aggressive behavior in the laboratory and in varsity and professional hockey players. Proceedings of the Royal Society of London, Series B, 275, 2651-2656) found that individual differences in facial WHR accounted for a significant proportion of the variance in aggressive behavior of men, but not women. I tested these two hypotheses in a sample of 470 Turkish university students. Facial WHR was measured from frontal photographs. I also measured the aggressiveness level of 212 individuals using the Buss and Perry aggressiveness questionnaire. The mean facial WHR (and standard deviation) was 1.89±0.12 for males and 1.91±0.11 for females. There was no relationship between facial WHR and the self-reported aggressive behavior for either sex. The facial WHR is not a sexually dimorphic characteristic (at least) for Turkish people, and it does not appear to be associated with self-reported trait aggression. © 2012 Elsevier Inc.

The Galatia volcanic complex (GVC) is one of two important volcanic complexes located in central Anatolia, Turkey. The study of potential field data can yield useful information about the subsurface magnetisation and density distribution. In this paper, a study of the thermal structural setting of the GVC using the analysis and interpretation of aeromagnetic data is presented. Volcanic rocks are the main cause of the magnetic anomalies that occur in the study region. A Curie-point-depth (CPD) map was constructed using the azimuthally averaged power spectrum of aeromagnetic anomaly data that was reduced-to-the-pole transformed (RTP); the map shows high geothermal potential for the GVC. The Curie point depths vary from about 6.74km to 16.9km and are consistent with the results of previous geothermal studies. The GVC exhibits low CPD and high heat-flow values (>100mWm-2). The CPD suggested that deep-seated magnetised sources continue downward up to 10km (inside the upper crust). A horizontal gradient analytic signal (HGAS) map exhibits the images and locations of deep-seated magnetised sources. In addition, the CPD and average Moho depth (33km, calculated from gravity anomaly data) are used to determine the presence of magnetic and non-magnetic crust in two cross sections taken from the GVC. The results presented should shed considerable light on some aspects of geothermal exploration in the GVC. © 2011 Elsevier B.V.

This case study presented herein compares the GIS-based landslide susceptibility mapping methods such as conditional probability (CP), logistic regression (LR), artificial neural networks (ANNs) and support vector machine (SVM) applied in Koyulhisar (Sivas, Turkey). Digital elevation model was first constructed using GIS software. Landslide-related factors such as geology, faults, drainage system, topographical elevation, slope angle, slope aspect, topographic wetness index, stream power index, normalized difference vegetation index, distance from settlements and roads were used in the landslide susceptibility analyses. In the last stage of the analyses, landslide susceptibility maps were produced from ANN, CP, LR, SVM models, and they were then compared by means of their validations. However, area under curve values obtained from all four methodologies showed that the map obtained from ANN model looks like more accurate than the other models, accuracies of all models can be evaluated relatively similar. The results also showed that the CP is a simple method in landslide susceptibility mapping and highly compatible with GIS operating features. Susceptibility maps can be easily produced using CP, because input process, calculation and output processes are very simple in CP model when compared with the other methods considered in this study. © 2009 Springer-Verlag.

In this study, the changes in the refractive index and intersubband optical absorption coefficients in symmetric double semi-V-shaped quantum wells are investigated theoretically. The energy levels and the envelope wave functions of an electron confined in finite potential double semi-V-shaped quantum wells are calculated within the effective-mass approximation framework. The analytical expressions of the refractive index and intersubband optical absorption coefficients are obtained using the compact density matrix approach. The effects of the incident optical intensity and structure parameters, such as the barrier width, confinement potential and the well width, on the optical properties of the double semi-V-shaped quantum wells are investigated. The numerical results show that both the incident optical intensity and structure paremeters have a great effect on the optical characteristics of these structures. © 2011 Elsevier B.V.
