Investigation of the kinetic regularities of the reaction of dry reforming of methane using nickel-containing catalysts based on cerium-zirconium oxides
In this study, we performed an investigation of the kinetics of the reaction of dry reforming of methane (DRM). For this work we used nickel-containing cerium-zirconium oxides. The catalysts were prepared in supercritical iso-propanol and characterized by means of XRD, TEM, XPS. It was found that the rate of DRM reaction becomes first order in methane and zero order in carbon dioxide. The dependences of the conversions of the reactants and product yields were obtained as a function of the contact time and the concentration of the initial mixture. In addition, the effective activation energy was calculated. It was shown that the most active and stable catalyst is 5wt% Ni/Ce0.5Zr0.5O[2]
ADRIA LITHOSPHERE INVESTIGATION ALPHA - Cruise No. M86/3, January 20 - February 04, 2012, Brindisi (Italy) - Dubrovnik (Croatia)
The Adriatic Sea and underlying lithosphere remains the least investigated part of the
Mediterranean Sea. To shed light on the plate tectonic setting in this central part of southern
Europe, R/V METEOR cruise M86/3 set out to acquire deep penetrating seismic data in the
Adriatic Sea. M86/3 formed the core of an amphibious investigation crossing Adria from the
Italian Peninsula into Montenegro/Albania. A total of 111 OBS/OBH deployments were
successfully carried out, in addition to 47 landstations both in Italy and Montenegro/Albania,
which recorded the offshore airgun shots.
In the scope of this shoreline-crossing study, the aim is to quantify the shallow geometry, deep
boundaries and the architecture of the southern Adriatic crust and lithosphere and to provide
insights on a possible decoupling zone between the northern and southern Adriatic domains.
Investigating the structure of the Adriatic crust and lithospheric mantle and analyzing the
tectonic activity are essential for understanding the mountain-building processes that underlie the
neotectonics and earthquake hazard of the Periadriatic region, especially in the vicinity of local
decoupling zones

Healthcare Staff Wellbeing, Burnout, and Patient Safety: A Systematic Review
Objective
To determine whether there is an association between healthcare professionals’ wellbeing and burnout, with patient safety.
Design
Systematic research review.
Data Sources
PsychInfo (1806 to July 2015), Medline (1946 to July 2015), Embase (1947 to July 2015) and Scopus (1823 to July 2015) were searched, along with reference lists of eligible articles.
Eligibility Criteria for Selecting Studies
Quantitative, empirical studies that included i) either a measure of wellbeing or burnout, and ii) patient safety, in healthcare staff populations.
Results
Forty-six studies were identified. Sixteen out of the 27 studies that measured wellbeing found a significant correlation between poor wellbeing and worse patient safety, with six additional studies finding an association with some but not all scales used, and one study finding a significant association but in the opposite direction to the majority of studies. Twenty-one out of the 30 studies that measured burnout found a significant association between burnout and patient safety, whilst a further four studies found an association between one or more (but not all) subscales of the burnout measures employed, and patient safety.
Conclusions
Poor wellbeing and moderate to high levels of burnout are associated, in the majority of studies reviewed, with poor patient safety outcomes such as medical errors, however the lack of prospective studies reduces the ability to determine causality. Further prospective studies, research in primary care, conducted within the UK, and a clearer definition of healthcare staff wellbeing are needed.
Implications
This review illustrates the need for healthcare organisations to consider improving employees’ mental health as well as creating safer work environments when planning interventions to improve patient safety
Results of a collaborative study on DNA identification of aged bone samples
AimA collaborative exercise with several institutes was organized by the Forensic DNA Service (FDNAS) and the Institute of the Legal Medicine, 2nd Faculty of Medicine, Charles University in Prague, Czech Republic, with the aim to test performance of different laboratories carrying out DNA analysis of relatively old bone samples. MethodsEighteen laboratories participating in the collaborative exercise were asked to perform DNA typing of two samples of bone powder. Two bone samples provided by the National Museum and the Institute of Archaelogy in Prague, Czech Republic, came from archeological excavations and were estimated to be approximately 150 and 400 years old. The methods of genetic characterization including autosomal, gonosomal, and mitochondrial markers was selected solely at the discretion of the participating laboratory. ResultsAlthough the participating laboratories used different extraction and amplification strategies, concordant results were obtained from the relatively intact 150 years old bone sample. Typing was more problematic with the analysis of the 400 years old bone sample due to poorer quality. ConclusionThe laboratories performing identification DNA analysis of bone and teeth samples should regularly test their ability to correctly perform DNA-based identification on bone samples containing degraded DNA and potential inhibitors and demonstrate that risk of contamination is minimized
