The paper performs a comparative determination of the hepatic and muscular catalase activity in three 2 summer-old cyprinids species, namely common carp (Cyprinus carpio), crucian (Carassius auratus gibelio) and bighead carp (Aristichthys nobilis), all coming from an intensive growth system. The results obtained evidence higher values (3.58 times higher in common carp, 6.55 higher in bighead carp and 2.07 higher in crucian, respectively) recorded by this marker-enzyme of oxidative stress, for al...

Abstract It is a challenging task for all Harbors or Naval Administration to restrict and monitor the movement of defense or commercial ships. Most commonly used techniques of monitoring are radars and satellite images. These techniques are not reliable as radars can be turned off voluntarily and receptions of images are affected by adverse climatic conditions. This paper proposes a reliable ship intruder detection algorithm that classifies different types of objects approaching the model system...

Abstract Seismic interferometry is one of the most effective techniques for detecting temporal variations in seismic velocity caused by large earthquakes. Before the 2011 Tohoku-Oki earthquake (M w 9.0) near the Japan Trench, a slow slip event (SSE, M w 7.0) and low-frequency tremors were observed near the trench. Here, we applied a seismic interferometry technique using ambient noise to data from 17 ocean bottom seismometers (OBSs) installed above the focal region before the main shock. We used...

Abstract Background Although evidence-based practice in healthcare has been facilitated by Internet access through wireless mobile devices, research on the effectiveness of clinical decision support for clinicians at the point of care is lacking. This study examined how evidence as abstracts and the bottom-line summaries, accessed with PubMed4Hh mobile devices, affected clinicians’ decision making at the point of care. Methods Three iterative steps were taken to evaluate the usefulness of PubMed...

Contradictions in public policies for biodiversity conservation are inherent in the complexity of the issues concerned and the relationships between stakeholders. How can conflicts of interest be reconciled? How can collective acceptance of conservation goals be improved? Topics for discussion are drawn from the example of policies for diadromous fish.

A lot of discrete configurations for the four-wave nonlinear interaction processes have been calculated and tested by the method proposed earlier in the frame of the concept of Fast Discrete Interaction Approximation to the Hasselmann's kinetic integral (Polnikov and Farina, 2002). It was found that there are several simple configurations, which are more efficient than the one proposed originally in Hasselmann et al. (1985). Finally, the optimal multiple Discrete Interaction Approximation...

The relationships between fish community δ15N and δ13C values and land use in watersheds and in buffer zones of nine French lakes were studied. The results showed inter-lakes variability of mean δ15N and δ13C values for different fish species. The study of correlations between fish δ15N and δ13C values and the proportions from different land use categories in watersheds showed a land use effect on fish δ15N values but not on δ13C values. The results underlined the great impact of manure...

Silica, SiO₂, in dissolved (DSi) and particulate (PSi) form, is both a major product of continental weathering as well as an essential nutrient in terrestrial and aquatic systems. Here we present estimates of the spatial distribution of riverine silica fluxes under natural conditions, i.e. without human influence, to ~140 segments of the global coastal zone. Focussing on the construction of the DSi budget, natural DSi concentration is multiplied with discharge of rivers for each segme...

The so-called "Concentration factor" (C.F.) should express a direct positive relationship between the concentration of a pollutant (e.g. metals, radioisotopes) in an organism and the concentration of the same pollutant in the water. While this index is very useful in some cases, it cannot give any information on the influence of the biota on its environment, an important topic in research on biogeochemical cycles. A new index (the Influence index) has consequently been developed to quantify the ...

The sediment composition of the coastal Lake San Puoto (Central Italy) was studied to obtain information on its recent environmental evolution (last 200 years). The explorative fieldwork was performed within the framework of the EU-funded PALICLAS Project. Sediment and mass accumulation rates, calculated from 210Pb analysis, show mean values of 0.27 cm y-1 and 0.11 g cm-2 y-1 respectively, with increasing values from 10 cm to the top (i.e. from ca 1960 AD to the present). The evolution of the re...

The European emission standards EURO 5 and EURO 6 define more stringent acceptable limits for exhaust emissions of new vehicles. The Exhaust Gas Recirculation (EGR) system is a partial but essential solution for lowering the emission of nitrogen oxides and soot particulates. Yet, due to a more intensive use than in the past, the fouling of the EGR system is increased. Ensuring the reliability of the EGR system becomes a main challenge. In partnership with PSA Peugeot Citroën, we designed an expe...

Abstract Background This systematic review will address the need for a better understanding of the impacts of fish entrainment and impingement associated with hydroelectric dams on fish productivity in freshwater temperate environments. As the number of dams continues to increase worldwide, so too has concerns for their effects on fish populations. Fish injury and mortality at hydroelectric facilities may have serious consequences for fish populations, which are generally the result of three mai...

Abstract Background Criminal offenders have a fundamental goal not to leave any traces at the crime scene. Some may suppose that items recovered underwater will have no forensic value, therefore, they try to destroy the traces by throwing items in water. These traces are subjected to the destructive environmental effects. This can represent a challenge for forensic experts investigating fingerprints. Methods The present study was conducted to determine the optimal method for latent fingerprints ...

While larval bivalves are highly sensitive to ocean acidification, the basis for this sensitivity and the longer-term implications of this sensitivity are unclear. Experiments were performed to assess the short-term (days) and long-term (months) consequences of larval stage exposure to varying CO₂ concentrations for calcifying bivalves. Higher CO₂ concentrations depressed both calcification rates assessed using ⁴⁵Ca uptake and RNA : DNA ratios in <i>Mercenaria me...

CO₂ emissions are leading to an acidification of the oceans. Predicting marine community vulnerability towards acidification is difficult, as adaptation processes cannot be accounted for in most experimental studies. Naturally CO₂ enriched sites thus can serve as valuable proxies for future changes in community structure. Here we describe a natural analogue site in the Western Baltic Sea. Seawater <i>p</i>CO₂ in Kiel Fjord is elevated for large parts of the year ...

The pollution of the marine ecosystem is a world-wide problem. Heavy metals and organochlorine compounds are among the most harmful elemental pollutants and are of particular concern because of their toxicity to humans. Anchovy (Engraulis encrasicolus, Linnaeus 1758), small pelagic fish with a key ecological role in the marine food web, is an important link connecting the lower and upper trophic levels, being also a valuable species for human consumption. Thus, anchovy samples were collected fro...

Gamma-interferon-inducible lysosomal thiol reductase (GILT) contains a CXXC active site motif that possesses thiol reductase activity by catalyzing the disulfide bond reduction of exogenous antigens. Mutating the active site of human GILT to change the cysteine residues to serine residues eliminates this property. Our previous study reported that Penaeus monodon GILT (PmGILT) contained a CXXS active site motif. Therefore, we assessed the enzymatic activity of PmGILT and demonstrated that it ...
