Copper and manganese in loggerhead turtles (Caretta caretta) tissues in the Mediterranean

The natural radionuclides 238U ,234Th, 40K and the main man-made 137Cs, have been studied inMytilus galloprovincialis (Lamarck, 1819) sampled in the Thermaikos gulf – North Aegean Sea, considered as a bioindicator for radiological assessment in the Mediterranean. The ratio 234U/238U has also been determined. In terms of 137Cs, the activity concentrations in seawater from the studied area have been measured as well, and the concentration factors of 137Cs in Mytilus galloprovincialis are given as a parameter of the organism response to radioactive pollution

Protocol for a mixed studies systematic review on the implementation of the recovery approach in adult mental health services

Introduction Recovery is integral to mental health planning in G-8 countries including Canada. A recovery-oriented approach to care aims to promote personal empowerment, illness self-management and a life beyond services for people with serious mental illness (SMI), while reducing the financial burden associated with mental illness. Although there is a growing body of literature on recovery, no synthesis of research on the implementation of recovery into mental health services exists. Objectives The objective is to conduct a mixed studies systematic review on the operationalisation of recovery into mental health services for adults with SMI. It will inform the transformation of Canadian services to a recovery orientation, but may be applicable to other countries. Methods and analysis Seven databases including PubMed, Ovid Medline, Ovid Embase, Ovid PsycInfo, CINAHL, the Cochrane Library and Scopus will be searched for peer-reviewed empirical studies published from 1998 to December 2016. Systematic reviews and studies using quantitative, qualitative and mixed methodologies will be included. Secondary searches will be conducted in reference lists of all selected full text articles. Handsearches will also be performed in the tables of contents of three recovery-focused journals for the last 5 years. International experts in the field will be contacted for comments and advice. Data extraction will include identification and methodological synthesis of each study; definition of recovery; information on recovery implementation; facilitators and barriers and study outcomes. A quality assessment will be conducted on each study. The data will be synthesised and a stepwise thematic analysis performed. Ethics and dissemination Ethics approval is not required for this knowledge synthesis. Findings will be disseminated through knowledge translation activities including: (1) a 1-day symposium; (2) presentations in national and international conferences and to local stakeholders; (3) publications in peer-reviewed journals; (4) posts on the organisational websites. © 2017 Article author(s) (or their employer(s) unless otherwise stated in the text of the article)

Copper and manganese in loggerhead turtles (Caretta caretta) tissues in the mediterranean

This research concerns the determination of copper and manganese concentrations in tissues of loggerhead turtles (Caretta caretta) found injured in various locations of Greek waters. The specimens were transported through the National Stranding Network run by ARCHELON to the Sea Turtle Rescue Centre, and were treated there. Measurement of copper and manganese form the beginning of a further research that includes measurement of Cd, Pb, Fe and Ni. Our intention was to obtain initial data values in several tissues of (Caretta caretta) in Greek waters and detect any bioaccumulation trend. In general the highest concentrations for both Cu and Mn were measured in the liver. The lowest concentrations for Cu were found in the muscle samples and for Mn in the lung samples. There was no indication of bioaccumulation for either of the two metals or the examined tissues. However, a negative trend was observed between curved carapace length (CCL) and (a) intestine copper concentration and (b) liver and lung manganese concentration. The comparison between specimens from various territories showed that the results were in agreement, taking into account the size of the specimens

Theory of games, decision making and strategic behavior

Στο δεύτερο και στο τρίτο κεφάλαιο γίνεται μία προσπάθεια να περιγραφούν οι βασικές αρχές της θεωρίας λήψης αποφάσεων με τελικό βήμα τον αλγόριθμο βελτίωσης πολιτικής. Στα επόμενα δύο κεφάλαια, περιγράφονται εκτενώς τα στατικά και τα δυναμικά παίγνια, καθώς και μέθοδοι εύρεσης σημείου ισορροπίας κατά Nash. Με τα εργαλεία αυτά, και με τη μελέτη βασικών μοντέλων δυοπωλίου, εξετάζονται οι συνθήκες για την ευστάθεια μίας σύμπραξης.Decisions are separated as decision under certainty, when all the information is availlable, decisions under uncertainty, when the decision process is stochastic, and decisions under conflict, such as games. In the second and third chapter, an effort is made to explain thoroughly the basic concepts of decision making, leading to an algorithm named "policy improvement". In forth and fifth chapter static and dynamic games are described extensively, in order to make the essential tools (chapter sixth and seventh) to examine the conditions for a stable cartel.Μαρία Ε.
