The mussel (Mytilus edulis) is successfully grown in aquaculture in Europe. Mussels are usually sold live and wet storage is becoming more common. In this study, oxygen demand and ammonia excretion were assessed at increasing water temperatures and different post-harvest situations. This information was used to calculate minimal flow rates per unit biomass of live mussels sufficient to keep oxygen above 5 mg L-1 or 50% saturation, and avoid accumulation of ammonia in commercial wet storage. In this study, rope-grown mussels were kept out of water for 8 h to simulate harvesting conditions and then re-immersed in holding tanks at 5, 10 and 15 C. Oxygen and ammonia concentrations were measured immediately after mussels were re-immersed (0 h), after 6 h and then every day for 3 days. After this period, the mussels were again kept out of water for 48 h to simulate long-distance transport and once again re-immersed for the same period as before. In the first 6 h after re-immersion, the oxygen consumption was between 7.5 and 12.2 μmol g-1 h-1 (dry flesh) and after this period it decreased to a standard level of around 4.0 ± 0.9 μmol g-1 h-1 and was independent of temperature. There were no major differences in oxygen consumption between mussels having spent 8 and 48 h out of water at any of the subsequent water temperatures used for re-immersion. In contrast, the ammonia excretion showed greater differences according to temperature and time out of water. Ammonia excretion was lowest at 5 C (<0.01 μmol g-1 h-1). The implications of these results for the industry and authorities are discussed considering the water flow rate, depuration specifications and energy costs. © EDP Sciences, IFREMER, IRD 2013.

Information onreference blood values in the literature is lacking for many wild rodents. In this study, comprehensive reference intervals (RIs) for a wide range of analytes from 101 healthy free-ranging nutria were determined. Animals were captured in Buenos Aires, Argentina (37°50′S, 57°34′W), and southward (38°60′S, 58°23′W), encompassing major biotopes of agricultural pampas with dunes and grassland steppes on the east coast. Traps were set at locations with high-density nutria populations (i.e., those areas that showed signs of movement, territorial marking, or feeding activities). Although the small sample size limits the interpretation of these findings, RIs were determined by a robust method using the central 95th percentile. In nutria, the RI range varied greatly for the leukocyte differentials, with mature neutrophils: 3,907-5,544/μl for females and 3,744-5,900/μl for males; band neutrophils: 0-10/μl for females and 3-18/μl for males; lymphocytes: 4,213-5,940/μl for both sexes combined; monocytes: 165-402/μl for both sexes combined; eosinophils: 13-91/μl for females and 108-165/μl for males; and basophils: 0-87/μl for both sexes combined. Platelet concentration was 543-727 × 109/L for both sexes combined. There was also a wide RI range for biochemistry values for some enzymes, such as alkaline phosphatase: 200-399 IU/L for both sexes combined; cholinesterase: 762-1,407 IU/L for females and 763-1,284 IU/L for males; creatine kinase: 182-552 IU/L for females and 162-451 IU/L for males; amylase: 853-1,865 IU/L for females and 779-1,293 IU/L for males; and glucose concentration 120.2-180.6 mg/dl for both sexes combined. Conversely, there was not a wide pooled RI range for calcium: 7.0-11.2 mg/dl; phosphorous: 6.1-9.3 mg/dl; sodium: 133.0-159.0 mEq/L; potassium: 3.0-8.2 mEq/L; chloride: 101.4-143.0 mEq/L; and urea: 11.3-36.8 mg/dl.The red blood cell indices had a narrow range, with mean corpuscular volume: 84.0 -102.5 fl and mean corpuscular hemoglobin concentration: 18.2-28.8 g/dl, and which was most likely due to strict physiologic controls. The results from this study were similar to those previously reported for farmed nutria. © 2012 American Association of Zoo Veterinarians.

Background: Shame is an acknowledged part of several psychopathological conditions, but is underrepresented in clinical research. Cook's Internalized Shame Scale (ISS) is the most promising measure, but has mostly been used for testing small clinical samples biased toward depressive pathology and female participants. Aims: To contribute to establishing indicators of pathological shame in outpatients with depression and anxiety disorder, and to contribute to establishing norms for the ISS in Scandinavia. Method: The ISS was administered to n= 200 gender balanced non-patient and outpatient samples. A total of 100 patients each were diagnosed as suffering from a depression or anxiety disorder. The diagnoses were supported by Beck's Depression (BDI) and Anxiety Inventory (BAI). The analyses used were the principal component analysis (PCA) and confirmatory factor analysis (CFA) for item structure and sample equivalence, ANOVAs, t-tests and MannWhitney non-parametric statistics for index scores, and the receiver operating curve (ROC) for break-off. Results: Patients' ISS score were similar to the results from previous research, the effect size of patientnon-patient difference was 0.68, correlations indicated a higher level of shame in depression than in anxiety, and the BDIBAI correlation was 0.56 for both clinical samples. The PCA showed three factors that were identified as: "Inadequacy", "Emptiness", and "Vulnerability". Conclusions: The ISS is a viable instrument, which indicates a widespread shame pathology in both depressive and anxious out-patients. The instrument may not be uni-dimensional, but exploration of factor variation may be a promising goal for further research. Clinical implications: Assessment of shame should be included in diagnosis and treatment of emotional disorder. © 2010 Informa UK Ltd.

The photoactive layer of a typical organic thin-film bulk-heterojunction (BHJ) solar cell commonly uses fullerene derivatives as the electron-accepting material. However, fullerene derivatives are air-sensitive; therefore, air-stable material is needed as an alternative. In the present study, we propose and describe the properties of Ti-alkoxide as an alternative electron-accepting material to fullerene derivatives to create highly air-stable BHJ solar cells. It is well-known that controlling the morphology in the photoactive layer, which is constructed with fullerene derivatives as the electron acceptor, is important for obtaining a high overall efficiency through the solvent method. The conventional solvent method is useful for high-solubility materials, such as fullerene derivatives. However, for Ti-alkoxides, the conventional solvent method is insufficient, because they only dissolve in specific solvents. Here, we demonstrate a new approach to morphology control that uses the molecular bulkiness of Ti-alkoxides without the conventional solvent method. That is, this method is one approach to obtain highly efficient, air-stable, organic-inorganic bulk-heterojunction solar cells.

This paper presents a novelistic method of earthquake and tsunami forecasting system and the design and testing of UWB antennas for predicting applications. One of the most exciting applications which require the UWB antenna is wideband capturing of the electromagnetic waves for wireless communication. These antennas transmit lower short microwave pulses (ten picoseconds to nanoseconds) into the space and detect the differentiated scattering due to the dielectric constant between normal and abnormal earth and ocean beats. An UWB compact antenna array is employed to conduct a 3D scan through a so-called digital beam forming in space time domain. © 2013 IEEE.

Antioxidant activities of aqueous extracts prepared from powdered leaves and stems of Salacia reticulata, a Salacia plant that grows in Sri Lanka, were investigated. Lipid peroxide levels and some hepatic injury markers in plasma, liver and/or kidney of mice treated with ferric nitrilotriacetate (Fe-NTA) were increased as compared to those of control mice. Oral preadministration of extracts of Salacia leaves and stems at doses of 100, 200 and 400 mg/kg body weight prevented the elevations of lipid peroxides and injury markers in a dose-dependent manner. Decrease of antioxidant activity in plasma of mice treated with Fe-NTA was also prevented by administration of these extracts. In in vitro study, well-known polyphenol components exhibited antioxidant activities, but other effective components were also present in these extracts. The results of this investigation indicate that the extracts of leaves and stems of S. reticulata could be beneficial as health foods for the prevention of oxidative stress-related disorders.
