Some sources of variation in the assessment when introducing unaccounted mortality due to discarding practices. The case of Southern Four spot megrim stock.

Four spot megrim (Lepidorhombus boscii) is widely distributed in Atlantic waters form Iceland to Cape Bojador. In ICES Divisions VIIIc and IXa, Portuguese and Spanish ships captured this species as by-catch mainly in mixed bottom trawl fisheries. Only one exploitation unit of this species is assessed (from Divisions VIIIc and IXa) in the ICES Working Group of Hake, Monk and Megrim. Discard data are not used in the assessment of this species, though they are considered significantly high for younger ages. Discards data are available for Spanish trawlers for 1993, 1994, 1997, and the period from 1999 to 2001. A simulation using discard data was made to avoid the underestimation of mortality and recruitment. Due to the change in January 1990 in the minimum legal size for this species in this area, it was decided not to use historical information previous to this year, as it is supposed that this change could substantially affect the fleet discard pattern. Different options were considered as the way of raising: by effort (number of trips, hour of trawling) or by landings (in weight or in number). Reasons for the final choices are explained for all options considered. The way to introduce discards data in the VPA procedure for assessment was through the catch at age matrix since we considered that no fish of this species survive after being discarded. Differences in yield of Short-term and Mediumterm projections were observed

Estimation of biomass of horse mackerel (Trachurus trachurus L.) in northern-Spain ( Nortbern IXa and VIIIc ) using the daily egg production method.

In order to estimate the spawning stock biomass of horse mackerel in the North Atlantic Spanish waters, a series of egg and adult cruises were carried out by lEO (Instituto Español de Oceanografía) and AZTI -SIO (Instituto de Investigación y Tecnología para la Oceanografía, Pesca y Alimentación) . The survey was carried out from 23 April to 25 May 1992. A total of 627 plankton samples and 37 adults samples were collected. A total daily egg production of 3.3 X 1012 egg (SE = 7.26 X 1011 , CV = 0.22) was estimated for the whole area sarnpled (ICES Division Vlllc and subdivision northern IXa north). The estirnate of horse mackerel spawning biornass ranged from 486,549 tons (CV = 0.34, when using adult pararneter estirnates exclusively frorn the Spanish survey, down to 368,814 tn (C = 0.32), when alternatively using an estimate of relative batch fecundity from the southern region of horse rnackerel western stock

Perfil antropométrico e consumo alimentar de atletas de Basquetebol em cadeira de rodas da região metropolitana de São Paulo

Objetivo: Analisar o perfil antropométrico e o consumo alimentar de atletas de basquetebol sobre cadeira de rodas da região metropolitana de São Paulo. Métodos: Estudo transversal, observacional realizado com uma amostra de jogadores de basquetebol em cadeira de rodas. O estado nutricional foi mensurado a partir das dobras cutâneas e circunferências corporais e o consumo alimentar foi avaliado por meio de um recordatório de 24 horas. O estudo foi aprovado pelo Comitê de Ética em Pesquisa do Centro Universitário São Camilo sob parecer 047/05. Resultados: Foram analisados 12 atletas com idade média de 29,75 (+4,9) anos. Verificou-se porcentagem de gordura corporal média de 26,54% (+7,9), com variações em relação ao tipo de paraplegia. Os atletas com maiores porcentagens de gordura corporal foram os portadores da síndrome pós-poliomielite. Quanto ao consumo alimentar, observou-se inadequações, principalmente em relação ao baixo consumo de carboidratos. Conclusão: Conclui-se que há a necessidade de outros estudos com paratletas desta modalidade, sendo fundamental a presença de um nutricionista nestas equipes. ABSTRACT Anthropometrics analysis and food consumption of athletes of wheelchair basketball in the metropolitan area of São PauloPurpose: Analyze the anthropometric profile and dietary intake of athlete’s wheelchair basketball over the metropolitan region of São Paulo. Methods: Cross-sectional, observational study with a sample of basketball players on wheels. The project was approved by the COER São Camilo University Center. The nutritional status was measured from skinfolds and body circumferences and dietary intake was assessed using a 24-hour recall. Results: 12 athletes with a mean age of 29.75 (4.9) years were analyzed. There was average percentage of body fat 26.54% (7.9), with variations in the type of paraplegia. Athletes with higher percentages of fat were the bearers of post- polio syndrome and observed low carbohydrate consumption. Conclusion: We conclude that there is a need for more studies to check the appropriate nutritional needs of this group, being essential the presence of a Nutritionist enabled

AI is a viable alternative to high throughput screening: a 318-target study

: High throughput screening (HTS) is routinely used to identify bioactive small molecules. This requires physical compounds, which limits coverage of accessible chemical space. Computational approaches combined with vast on-demand chemical libraries can access far greater chemical space, provided that the predictive accuracy is sufficient to identify useful molecules. Through the largest and most diverse virtual HTS campaign reported to date, comprising 318 individual projects, we demonstrate that our AtomNet® convolutional neural network successfully finds novel hits across every major therapeutic area and protein class. We address historical limitations of computational screening by demonstrating success for target proteins without known binders, high-quality X-ray crystal structures, or manual cherry-picking of compounds. We show that the molecules selected by the AtomNet® model are novel drug-like scaffolds rather than minor modifications to known bioactive compounds. Our empirical results suggest that computational methods can substantially replace HTS as the first step of small-molecule drug discovery

Evolución de los recursos pesqueros y de las tecnologías pesqueras en los últimos años

El artículo aborda tanto aspectos de flota como de recursos, describiendo el sector pesquero vasco y la evolución de los distintos sub-sectores que la agrupan. Posteriormente se centra en resúmenes por flota, en el que se dan detalles tanto de las características generales de las flotas como del estado de los recursos en los que basan su actividad.Artikulu honek flota alderdiei zein baliabide alderdiei heltzen die, eta euskal arrantza sektorea eta haren barnean biltzen diren azpisektoreen bilakaera deskribatzen ditu. Gero, flota bakoitzari buruzko laburpenak agertzen dira, bai floten ezaugarri orokorrak emanez, baita bere jardueraren oinarrian diren baliabideen egoera bajura ere.L'article aborde aussi bien les aspects de flotte que de ressources, décrivant le secteur de la pêche basque et l'évolution des différents sous-secteurs qui la regroupent.
