Agrinio, Greece

Τhe University of Western Greece was a 3-campus university in West Greece. Founded in 2009, in Agrinio, and is the newest university in Greece. On September 2009, the University of Western Greece absorbed three departments that had previously formed part of the University of Ioannina. On April of 2013 it was absorbed by the University of PatrasThe language of instruction is Greek, although there are programs in foreign languages and courses for international students, which are carried out in English, French, German, and Italian.Independent DepartmentsΔιαχείρισης Περιβάλλοντος και Φυσικών Πόρων Διοίκησης Επιχειρήσεων Αγροτικών Προϊόντων και Τροφίμων Διαχείρισης Πολιτισμικού Περιβάλλοντος και Νέων Τεχνολογιών Wikipedia.

During validation and verification of the system for the proper implementation of HACCP principles, it is essential to rely on microbiological data. Considerable science research has been carried out during the last twenty years on sampling and testing of carcasses for hygiene criteria. This includes the preferable indicator microorganisms to be used, in order to indicate the general hygiene of slaughtering procedures, the evaluation of microbiological data gathered and the sampling methods. Furthermore, European Union (EU) and the United States have adopted the procedures for HACCP validation and verification in their legislation. The aim of this review is to demonstrate the relevant modern trends in this field of food science. In conclusion, microbiological data based on the indicators should be interpreted only to assess general trends in the hygiene process of the operator in order to take corrective action. Microbiological results, obtained only at the end of the slaughtering process, do not provide information on the cause of the problem. Therefore, 'process-based' microbiological criteria which are based on values measured at various stages of the process, including final carcass values, should be used. Finally, in order to implement an adequate monitoring system, non-destructive techniques of carcass sampling could be used instead of excision. The microbial recovery may be lower, but it is proportional to the excision recovery and therefore, non-destructive techniques, like swabbing with sponges, could be a practical sampling method for the estimation of indicators during the slaughtering procedure and hygiene evaluation. © 2014 Elsevier Ltd.

Wind energy resources in the Ionian-Adriatic coast of South-East Europe were analyzed. Status of wind energy development in the countries of Greece, Albania, Montenegro, Bosnia-Herzegovina, and Croatia and regions of moderate and high wind potential at their west coasts were reviewed. The feasibility of the application of specific wind turbine generators with lower cut-in, cut-out, and rated speeds in moderate wind fields was investigated. The wind speed and direction as well as the availability, the duration, and the diurnal variation of several coastal sites in Western Greece were assessed, and the results were statistically analyzed as time-series or with the Weibull probability distribution function. The mean wind power densities were less than 200 W m -2 at 10 m, suggesting the limiting suitability of the sites for the usual wind energy applications. However, further technical-economical analysis revealed that the recent technological turbine improvements with lower cut-in and rated speeds make wind power viable even at moderate wind fields. Environmental indicators like energy payback period and avoided greenhouse emissions were determined to be significant for the utilization of wind energy resources in these coastal areas. Since the region is important for sea-related activities, the implementation of wind energy applications in the frame of cross-border cooperation should be prioritized. © 2013 AIP Publishing LLC.

The importance of host-specialization to speciation processes in obligate host-associated bacteria is well known, as is also the ability of recombination to generate cohesion in bacterial populations. However, whether divergent strains of highly recombining intracellular bacteria, such as Wolbachia, can maintain their genetic distinctness when infecting the same host is not known. We first developed a protocol for the genome sequencing of uncultivable endosymbionts. Using this method, we have sequenced the complete genomes of the Wolbachia strains wHa and wNo, which occur as natural double infections in Drosophila simulans populations on the Seychelles and in New Caledonia. Taxonomically, wHa belong to supergroup A and wNo to supergroup B. A comparative genomics study including additional strains supported the supergroup classification scheme and revealed 24 and 33 group-specific genes, putatively involved in host-adaptation processes. Recombination frequencies were high for strains of the same supergroup despite different host-preference patterns, leading to genomic cohesion. The inferred recombination fragments for strains of different supergroups were of short sizes, and the genomes of the co-infecting Wolbachia strains wHa and wNo were not more similar to each other and did not share more genes than other A- and B-group strains that infect different hosts. We conclude that Wolbachia strains of supergroup A and B represent genetically distinct clades, and that strains of different supergroups can co-exist in the same arthropod host without converging into the same species. This suggests that the supergroups are irreversibly separated and that barriers other than host-specialization are able to maintain distinct clades in recombining endosymbiont populations. Acquiring a good knowledge of the barriers to genetic exchange in Wolbachia will advance our understanding of how endosymbiont communities are constructed from vertically and horizontally transmitted genes. © 2013 Ellegaard et al.

In the current study the effects of chloride-induced corrosion, in terms of mechanical properties and pit depths, are evaluated on B500c steel bars embedded in concrete (embedded samples) and directly exposed (bare samples), immersed in a salt spray chamber. The results indicate that for the same level of mass loss, degradation of the "embedded" samples was found to be much more severe than that of the "bare samples", in terms of losses in yield strength and uniform elongation. Analysis of the statistical significance of the pit depth and area values measured, based on a methodology developed using advanced imaging analysis, indicate that degradation of the steel bars embedded in concrete produced a more severe pitting corrosion in terms of depth of pitting, compared to the steel samples directly exposed to the same corrosive medium, for the same (on average) mass loss. © 2012 Elsevier Ltd.

Pesticides still constitute an integral part of modern agriculture. Upon their release, pesticides interact with soil microbes in contrasting ways. On the one hand they stimulate microbial activity and proliferation of a specific fraction of the microbial community which could utilize them as energy source resulting in their rapid biodegradation and loss of biological efficacy. On the other hand they induce inhibitory effects on the structure and/or on the function of the microbial community, the latter having detrimental effects on ecosystem functioning. So far pesticide legislation has largely ignored these aspects and pesticide soil ecotoxicity tests relies solely on simple C and N mineralization tests which do not provide a reliable assessment of pesticide impact on soil microbes. The introduction of fingerprinting molecular methods, qPCR, high throughput sequencing analysis, microarrays and omics have substantially advanced our knowledge on soil microbial ecology. However, these dynamic tools have not been utilized yet to shed light into soil microbes - pesticides interactions. This project aims to introduce these highly dynamic tools in combination with chemical analysis of pesticides and their metabolites to shed light into those interactions and the factors deciding which way the balance with go (stimulation or inhibition). This will be achieved via collaboration of two industrial and three academic partners with complementary expertise in molecular microbial ecology, soil microbiology, pesticide metabolism and the establishment of a staff exchange scheme. This apart from the achievement of the scientific and technological goals of the project will facilitate technology transfer between partners and open communication channels between Academia - Industry. Further the project is expected to support increasing communication with standardization foundations (ISO) and EU policy making bodies regarding pesticides (EFSA)
