An intercomparison study of the determination of sulfite in tropical shrimps by the West European Fish Technologists' Association (WEFTA) OMA
Luten, J.; Bouquet, W.; Oehlenschläger, J.; Meetschen, U.; Etienne, M.; Stroud, G.; Bykowski, P.; Batista, I.; Vyncke, W.; Stefansson, G..
Eight WEFTA laboratories participated in two series of intercomparison exercises on sulfite determination in tropical shrimps. Samples of tropical shrimps were spiked with sodium metabisulfite (Na<sub>2</sub>S<sub>2</sub>O<sub>5</sub>) and hydroxymethylsulfonate (HMS) at a level of 25-90 mg SO<sub>2</sub>/kg. Most of the laboratories determined the sulfite content with (modified) methods of Monier-Williams or De Vries et al. The overall mean recovery of sulfite was rather low (47-60%), which may be attributed to an irreversible reaction of sulfite with the tropical shrimps. The repeatability of the methods within the participating laboratories was good. However, reproducibility among the laboratories was...

Silva,Diego Rafael Palma da; Silva,Gabriele Biavaschi; Corte,Flávio Desessards De La; Brass,Karin Erica; Pozzobon,Ricardo; Dau,Stefano Leite; Gasperi,Diego de; Freitas,Gabrielle Coelho.
ABSTRACT: This study evaluated the quality of anesthesyc recovery of horses using a three-point assisted method. Sixty-eight horses (37 females and 31 males) of different breeds, age and weight submitted to general anesthesia for abdominal - ABD (n=15), arthroscopy - ART (n=17), other orthopedic - ORT (n=18) and miscellaneous - MIX (n=18) surgical procedures. Isoflurane resulted in shorter recovery time (67.4±25.7min) compared to halothane (88.0±37.8min). The mean duration (±SD) of anesthesia for ABD, ORT, ART and MIXgroups was 166.7 (±14), 54.9 (±5.9), 86.5 (±7.3) and 76.4 (±32.5) minutes (min) respectively. Quality of recovery wasn’t influenced by duration of anesthesia or by use of analgesic, sedative and/or anesthetic drugs or not (p>0.05). Mean...

Apparent recovery of surface applied nitrogen fertilizer by a coastcross pasture. Repositório Alice
PRIMAVESI, A. C.; PRIMAVESI, O.; CORRÊA, L. A.; CANTARELLA, H.; SILVA, A. G..
Nitrogen recoveries from fivel levels of urea and ammonium nitrate surface-applied on coastcross pasture, grown on a dark red lotosol (Hapludox), in Sao Carlos, SP, Brazil under tropical altitude climate, were estimated. Significant differences occurred within periods (P<0.05), depending on climatic conditions. Under adequate plant growth conditions, mean N recovery from urea was about 67%, sometimes reaching 80% of that from ammonium nitrate. Recovery of ammonium nitrate varied from 45 to 68% of applied N.

Benzocaine and clove oil as anesthetics for pejerrey (Odontesthes bonariensis) fingerlings Arq. Bras. Med. Vet. Zootec.
Morato-Fernandes,J.; Tavares,R.A.; Rocha,C. B.; Pouey,J.L.O.F.; Piedras,S.R.N..
Pejerrey (Odontesthes bonariensis) is a native species from Rio Grande do Sul, Uruguay and Argentina where it is of great economic importance for artisanal fishing. One difficulty in laboratory research with pejerrey is related to its sensitivity, as it presents higher basal cortisol levels than other freshwater species. For this reason, the aim of this work was to evaluate the efficiency of benzocaine and clove oil as anesthetics for pejerrey fingerlings. Two experiments were done where fingerlings (57±7.8mm and 1.1±0.44g) were exposed to benzocaine with concentrations between 40mgL-1 and 120mgL-1 and to clove oil with concentrations between 12mgL-1 and 75mgL-1. Survival, anesthesia induction time and recovery time for each pharmaceutics were evaluated....

Cyclosporin-A does not affect skeletal muscle mass during disuse and recovery BJMBR
Aoki,M.S.; Miyabara,E.H.; Soares,A.G.; Salvini,T.F.; Moriscot,A.S..
Cyclosporin-A (CsA) is an immunosuppressive drug that acts as an inhibitor of calcineurin, a calcium phosphatase that has been suggested to play a role in skeletal muscle hypertrophy. The aim of the present study was to determine the effect of CsA administration (25 mg kg-1 day-1) on skeletal muscle mass and phenotype during disuse and recovery. Male Wistar rats received vehicle (N = 8) or CsA (N = 8) during hind limb immobilization (N = 8) and recovery (N = 8). Muscle weight (dry/wet) and cross-sectional area were evaluated to verify the effect of CsA treatment on muscle mass. Muscle phenotype was assessed by histochemistry of myosin ATPase. CsA administration during immobilization and recovery did not change muscle/body weight ratio in the soleus (SOL)...

There is a wealth of literature on the design of ex post compensation mechanisms for natural disasters. However, more research needs to be done on the manner in which these mechanisms could steer citizens toward adopting individual-level preventive and protection measures in the face of flood risks. We have provided a comparative legal analysis of the financial compensation mechanisms following floods, be it through insurance, public funds, or a combination of both, with an empirical focus on Belgium, the Netherlands, England, and France. Similarities and differences between the methods in which these compensation mechanisms for flood damages enhance resilience were analyzed. The comparative analysis especially focused on the link between the recovery...

Deep-sea nematode assemblage has not recovered 26 years after experimental mining of polymetallic nodules (Clarion-Clipperton Fracture Zone, Tropical Eastern Pacific) ArchiMer
Miljutin, Dmitry M.; Miljutina, Maria A.; Arbizu, Pedro Martinez; Galeron, Joelle.
We investigated nematode assemblages inhabiting the 26-year-old track created by experimental deep-sea mining of polymetallic nodules, and two adjacent, undisturbed sites, one with nodules and one without nodules. The aim was to compare density, assemblage structure, and diversity indices in order to assess the process of recovery of the nematode assemblage inhabiting the disturbed site. This experimental dredging was conducted in 1978 by the Ocean Minerals Company (USA) in the area of a French mining claim in the Clarion-Clipperton Fracture Zone (Tropical Eastern Pacific) at a depth of about 5000 m. The nematode assemblage had not returned its initial state 26 years after the experimental dredging: the total nematode density and biomass within the...

Defining viable recovery paths toward sustainable fisheries ArchiMer
Martinet, Vincent; Thebaud, Olivier; Doyen, L.
This paper develops a formal analysis of the recovery process for a fishery, from crisis situations to desired levels of sustainable exploitation, using the theoretical framework of viable control. We define sustainability as a combination of biological, economic and social constraints which need to be met for a viable fishery to exist. Biological constraints are based on the definition of a minimum resource stock to be preserved. Economic constraints relate to the existence of a guaranteed profit per vessel. Social constraints refer to the maintenance of a minimum size of the fleet, and to the maximum speed at which fleet adjustment can take place. Using fleet size adjustment and fishing effort per vessel as control variables, we first identify the states...

Disaster Preparation and Recovery: Lessons from Research on Resilience in Human Development Ecology and Society
Masten, Ann S; University of Minnesota; amasten@umn.edu; Obradovi&#263;, Jelena; University of British Columbia; jelena.obradovic@ubc.ca.
Four decades of theory and research on resilience in human development have yielded informative lessons for planning disaster response and recovery. In developmental theory, resilience following disaster could take multiple forms, including stress resistance, recovery, and positive transformation. Empirical findings suggest that fundamental adaptive systems play a key role in the resilience of young people facing diverse threats, including attachment, agency, intelligence, behavior regulation systems, and social interactions with family, peers, school, and community systems. Although human resilience research emphasizes the adaptive well-being of particular individuals, there are striking parallels in resilience theory across the developmental and...

Golalipour,Mohammad Jafar; Roshandel,Danial; Roshandel,Gholamreza; Ghafari,Soraya; Kalavi,Mergen; Kalavi,Khodaberdi.
Lead is one of the most important environmental pollution which is toxic to many organ systems. D-penicillamine (D-P) is a chelator drug which is used for treatment of lead toxicity for several years. This study was conducted in order to evaluate the efficacy of D-P in reducing the effects of lead on hematological indices. This study was done on 36 male adult, 6-8 weeks albino Wistar rats in Gorgan University of Medical Sciences. At first male adult rats were exposed to lead acetate in their drinking water. After 8 weeks, 6 rats were selected and blood samples were prepared to assess the effects of lead toxicity. The remained lead exposed rats were divided into recovery and treatment groups where distilled water and D-P was administered for them,...

NETTO,JOSÉ D. LIMMA; OLIVEIRA,REBECA S.M.; COPATTI,CARLOS EDUARDO.
ABSTRACT This study aimed to verify the sedative and anaesthetic effect of the essential oils of basil (Ocimum basilicum) (EOOB) and lemongrass (Cymbopogum flexuosus) (EOCF) in Nile tilapia juveniles. The fish were transferred to aquaria containing different concentrations of each essential oil: 10, 25, 50, 100, 200, 400 and 600 μL L-1. The time of sedation ranged from 7 to 31 seconds and the recommended concentration was 10 or 25 μL L-1 for both essential oils. The best times for anaesthesia and recovery were found for the concentrations of 400 μL L-1 for EOOB (135.2 and 199.1 seconds, respectively) and 600 μL L-1 for EOCF (327.1 and 374.8 seconds, respectively). In conclusion, we recommend the use of EOOB and EOCF for the sedation and anaesthesia of Nile...

Environment, facilities, and management of hospital pens in growing and finishing pig farms: a descriptive study R. Bras. Zootec.
Pierozan,Carlos Rodolfo; Dias,Cleandro Pazinato; Silva,Caio Abércio da.
ABSTRACT The objective of this study was to describe the housing system in the hospital pens on growing and finishing (GF) pig farms. This work was developed by using a questionnaire and was conducted between January and April, 2016. Forty-four GF commercial farms (a total of 41,111 animals) were involved, seeking to raise issues concerning the facilities of the hospital pens, environment, management, feeding and the reasons for transferring the animals to these accommodations. About 98% of the evaluated farms had, at least, one hospital pen. Most of these farms presented a percentage of animals evaluated (PAE) in the infirmary, of less than 1.5% of the total capacity of the animal housing on the farm. In 93.48% of the farms, the criterion used to transfer...

Fate of nitrogen (15N) from velvet bean in the soil-plant system Scientia Agricola
Scivittaro,Walkyria Bueno; Muraoka,Takashi; Boaretto,Antonio Enedi; Trivelin,Paulo César Ocheuze.
Because of their potential for N2 biological fixation, legumes are an alternative source of nitrogen to crops, and can even replace or supplement mineral fertilization. A greenhouse experiment was carried out to evaluate temporal patterns of velvet bean (Mucuna aterrima) green manure release of nitrogen to rice plants, and to study the fate of nitrogen from velvet bean in rice cultivation. The isotopic dilution methodology was used. Treatments consisted of a control and 10 incubation periods of soil fertilized with 15N-labeled velvet bean (0, 20, 40, 60, 90, 120, 150, 180, 210, and 240 days). The plant material was previously chopped, sifted (10 mm mesh sieve) and oven-dried (65ºC). Incubation of the plant material (2.2 g kg-1 soil) was initiated by the...
