- Exposure to combustion engine exhaust and its effect on crews of roll-on roll-off ships and car ferries and on bus garage staff were studied. The peak concentrations recorded for some of the substances studied were as follows: total particulates (diesel only) 1.0 mg/m3, benzene (diesel) 0.3 mg/m3, formaldehyde (gasoline and diesel) 0.8 mg/m3, and nitrogen dioxide (diesel) 1.2 mg/m3. The highest observed concentration of benzo(a)pyrene was 30 ng/m3 from gasoline and diesel exhaust. In an experimental study volunteers were exposed to diesel exhaust diluted with air to achieve a nitrogen dioxide concentration of 3.8 mg/m3. Pulmonary function was affected during a workday of occupational exposure to engine emissions, but it normalized after a few days with no exposure. The impairment of pulmonary function was judged to have no appreciable, adverse, short-term impact on individual work capacity. In the experimental exposure study, no effect on pulmonary function was observed. Analyses of urinary mutagenicity and thioether excretion showed no sign of exposure to genotoxic compounds among the occupationally exposed workers or among the subjects in the experimental study.

- Background: There is scarce information about European folk knowledge of wild invertebrate fauna. We have documented such folk knowledge in three regions, in Romania, Slovakia and Croatia. We provide a list of folk taxa, and discuss folk biological classification and nomenclature, salient features, uses, related proverbs and sayings, and conservation. Methods: We collected data among Hungarian-speaking people practising small-scale, traditional agriculture. We studied "all" invertebrate species (species groups) potentially occurring in the vicinity of the settlements. We used photos, held semi-structured interviews, and conducted picture sorting. Results: We documented 208 invertebrate folk taxa. Many species were known which have, to our knowledge, no economic significance. 36 % of the species were known to at least half of the informants. Knowledge reliability was high, although informants were sometimes prone to exaggeration. 93 % of folk taxa had their own individual names, and 90 % of the taxa were embedded in the folk taxonomy. Twenty four species were of direct use to humans (4 medicinal, 5 consumed, 11 as bait, 2 as playthings). Completely new was the discovery that the honey stomachs of black-coloured carpenter bees (Xylocopa violacea, X. valga) were consumed. 30 taxa were associated with a proverb or used for weather forecasting, or predicting harvests. Conscious ideas about conserving invertebrates only occurred with a few taxa, but informants would generally refrain from harming firebugs (Pyrrhocoris apterus), field crickets (Gryllus campestris) and most butterflies. We did not find any mythical creatures among invertebrate folk taxa. Almost every invertebrate species was regarded as basically harmful. Where possible, they were destroyed or at least regarded as worth eradicating. However, we could find no evidence to suggest any invertebrate species had suffered population loss as a result of conscious destruction. Sometimes knowledge pertaining to the taxa could have more general relevance, and be regarded as folk wisdom concerning the functioning of nature as a whole. Conclusions: The high number of known invertebrate folk taxa suggests that it would be worth conducting further investigations in other areas of Europe.

Folk knowledge of non-domestic mammals among ethnic Hungarians in North-Western Romania

- Most ethnobiological research on mammals has focused on the domesticated species and largely ignored the wild taxa. We carried out a research among the ethnic Hungarians in Nusfalau, Romania, to document the local ecological knowledge on mammals. We studied which kinds of local wild mammals the villagers know, which folk taxa they can identify, the names they use for these taxa, and what do they know about the morphological, behavioural and ecological characteristics, as well as the economical impact of these mammals. Twenty persons were interviewed with the aid of colour photographs of 62 mammal species. Five hundred and twenty three individual data on the various folk taxa were thus gathered. The majority of the interviewees were still possessed surprisingly detailed and precise knowledge on the wild species living in their surroundings. They classified the 62 mammal species into 42 folk taxa and grouped them into 11 larger sets. The groupings were almost similar to the scientific classification except for one group which mainly contained mice and voles. The eastern hedgehog (Erinaceus roumanicus) had a unique taxonomy with two highly distinct folk taxa. The characteristics of the known folk taxa were described according to their morphological, ethological-ecological, and cultural salience. In the case of physical appearance, naming of a prototype and comparing to it was typical. In terms of ecological salience of feeding habit, characteristics of movement, habitat, breeding habit, bashfulness, voice, annual and daily pattern of behaviour, and observability were the most important characteristics. The comparison to humans was particularly important when describing behaviour. In terms of cultural salience, the characterization of harm caused and benefit gained was unequivocally dominant. The overwhelming majority of the species were known through personal experience. The effect of books and media was negligible. Local knowledge of wild animals is part of our common European cultural heritage. This knowledge is fading rapidly, and most of it may be lost in the next decades.

- Statements on childhood overweight and obesity (COO) have focused on different avenues for prevention and treatment, critical stages of the life cycle, including pregnancy and lactation, individual, family, school and community-based interventions, multidisciplinary family programmes and multicomponent interventions. This commentary is concerned with the less-addressed relationship between COO and inequality. It describes current global patterns of inequality and COO and the ways in which those inequalities are linked to COO at micro-level, meso-level and macro-level. It then describes current programmatic approaches for COO inequality, preventive and medical, and considers important pitfalls in the framing of the problem of COO and inequality. It ends with describing how childhood and adolescent overweight and obesity prevention and treatment programmes might be formulated within broader socio-political frameworks to influence outcomes.

The isotope effect on divertor conditions and neutral pumping in horizontal divertor configurations in JET-ILW Ohmic plasmas

- Understanding the impact of isotope mass and divertor configuration on the divertor conditions and neutral pressures is critical for predicting the performance of the ITER divertor in DT operation. To address this need, ohmically heated hydrogen and deuterium plasma experiments were conducted in JET with the ITER-like wall in varying divertor configurations. In this study, these plasmas are simulated with EDGE2D-EIRENE outfitted with a sub-divertor model, to predict the neutral pressures in the plenum with similar fashion to the experiments. EDGE2D-EIRENE predictions show that the increased isotope mass results in up to a 25% increase in peak electron densities and 15% increase in peak ion saturation current at the outer target in deuterium when compared to hydrogen for all horizontal divertor configurations. Indicating that a change from hydrogen to deuterium as main fuel decreases the neutral mean free path, leading to higher neutral density in the divertor. Consequently, this mechanism also leads to higher neutral pressures in the sub-divertor. The experimental data provided by the hydrogen and deuterium ohmic discharges shows that closer proximity of the outer strike point to the pumping plenum results in a higher neutral pressure in the sub-divertor. The diaphragm capacitance gauge pressure measurements show that a two to three-fold increase in sub-divertor pressure was achieved in the corner and nearby horizontal configurations compared to the far-horizontal configurations, likely due to ballistic transport (with respect to the plasma facing components) of the neutrals into the sub-divertor. The corner divertor configuration also indicates that a neutral expansion occurs during detachment, resulting in a sub-divertor neutral density plateau as a function of upstream density at the outer-mid plane.
