Northern Shrimp (Pandalus borealis, Krøyer) from EU-Spain Bottom Trawl Survey 2018 in NAFO Div. 3LNO

The Spanish Institute of Oceanography carried out in 2018 two bottom trawl surveys in the NAFO Regulatory Area in Division 3NO and 3L during the months of June and August respectively. The results on Northern shrimp (Pandalus borealis) are presented and compared with those from previous surveys from the same series. As recent years in 2018the shrimp catch (0.528 kg.) and estimated biomass (2.413 t.) in Divisions 3NO remain between the lowest of the series, confirming the decrease of shrimp importance from 2004. The Northern shrimp catches in 3L Division have declined from 2009, the shrimp catch (1352 kg.) and biomass estimated in 2018 (7807 t.) remain between the lowest values in the historical series

Results of Exploratory Deep-sea Fishing Survey in the Galician Bank: Biological Aspects on Some of Seamount-associated Fish (ICES Division IXb)

Since October 1998 to October 1999 an experimental survey, comprising 12 monthly fishing trips were carried out in Galician Bank (ICES Divisions IXb) by two commercial trawlers of the Spanish fleet. The aims of this survey were to explore the fishing resources of studied area and to know the species community associated to this seamount. A total of 297 valid hauls were made during 309 hours of fishing and yielded a total catch of 45 145 kg in the depth strata studied (650-1200 m). The community of species in the area prospected presented high species richness. A total of 106 species were made up of 70 teleosts, 11 sharks, 3 rays, 2 chimaeras, 11 crustacea, 6 molluscs and 3 equinoderms The most important species captured were teleosts: H. mediterraneus, M.moro, L. eques, A. bairdii, E. telescopus, T. cristulata and L. piscatorius, followed for deep sharks: D. licha, D. calceus and crustacean: Ch affinis. The yields obtained for the whole series of fishing trips were low being the values obtained by order of importance: 30.3, 14.0, 13.1, 11.7, 4.8, 4.2, 2.5 kg/h and 1 kg/h for the teleosts; 2.0, 1.7, kg/h for sharks and 1.2 kg/h for crustacean. The results indicate, in general, there were no differences in depth distribution of the species characterised by the presence or absence of certain species and also, a seasonal variation in the abundance of the most important caught

The feeding of American plaice (Hippoglossoides platessoides), Redfish (Sebastes marinus) and Cod (Gadus morhua) in the Flemish Cap during July 1988

A randomly stratified bottom-trawl survey was realized in the Flemish Cap (NAFO Div. 3M) in July 1988. The stomach contents of three species were studied: 320 of American plaice (Hippoglossoides platessoides), 203 of redfish (Sebastes Marinus) and 468 of cod (Gadus morhua). The cod specimens were classified taking into account age groups; in the case of other species by length classes. The food items, the prey occurrence index and the diversity index were determined too. The Schoener overlap index was calculated to study the intraspecific diet overlap in cod and the interspecific diet overlap between the three species. The relation between predator size (cod) and prey size (redfish) was also studied

Isotopic cross sections of fragmentation residues produced by light projectiles on carbon near 400A MeV

We measured 135 cross sections of residual nuclei produced in fragmentation reactions of 12C, 14N, and 13−16,20,22 O projectiles impinging on a carbon target at kinetic energies of near 400 A MeV, most of them for the first time, with the R3B/LAND setup at the GSI facility in Darmstadt (Germany). The use of this state-of-the-art experimental setup in combination with the inverse kinematics technique gave the full identification in atomic and mass numbers of fragmentation residues with a high precision. The cross sections of these residues were determined with uncertainties below 20% for most of the cases. These data are compared to other previous measurements with stable isotopes and are also used to benchmark different model calculations.This work has been partially supported by the Spanish Ministry for Science and Innovation under Grants No. PGC2018-099746-B-C21, No. PGC2018-099746-B-C22, and No. PID2019-104390GB-100; Xunta de Galicia under program “Grupos de referencia competitiva” (Project No. ED431C 2017/54); the German Bundesministerium für Bildung und Forschung (BMBF) (Grants No. 05P12RDFN8, No. 05P15RDFN1, and No. 05P19RDFN); the Swedish Research Council; and U.S. Department of Energy Grant No. DE-FG02-08ER41533.

In the present paper, the authors list the tropical fish species recorded in Galician Atlantic waters during 1996-1997: Hoplostethus cadenati Quéro, 1974; Neoscopelus macrolepidotus Johnson, 1863; Nettastoma melanura Rafinesque, 1810; Halosaurus ovenii Johnson, 1863; Cyttopsis roseus (Lowe, 1843); Chaunax pictus Lowe, 1846; Caranx crysos (Mitchill, 1815); Pseudocaranx dentex (Blochampersand Schneider in Schneider 1801) and Dasyatis violacea (Bonaparte, 1832). They also review the distribution of these species in the east Atlantic, and briefly describe some of the specimens captured. The captures of Dasyatis violacea, Neoscopelus macrolepidotus and Nettastoma melanura are the first records of these species in Galician Atlantic waters. The new record for Galician waters of Neoscopelus macrolepidotus also indicates a new northern limit for this species in the northeast Atlantic.En el presente trabajo se recoge la captura de especies de afinidades tropicales presentes en aguas atlánticas de Galicia durante 1996-1997: Hoplostethus cadenati Quéro, 1974; Neoscopelus macrolepidotus Johnson, 1863; Nettastoma melanura Rafinesque, 1810; Halosaurus ovenii Johnson, 1863; Cyttopsis roseus (Lowe, 1843); Chaunax pictus Lowe, 1846; Caranx crysos (Mitchill, 1815); Pseudocaranx dentex (Blochampersand Schneider en Sceneider, 1801) y Dasyatis violacea (Bonaparte, 1832).

Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication.

The PET system design consists of 4 rings of 16 detector modules each and it is expected to be integrated in a head dedicated radio frequency coil of an MR scanner. The PET modules are based on monolithic LYSO crystals coupled by means of optical devices to an array of 256 Silicon Photomultipliers. These types of crystals allow to preserve the scintillation light distribution and, thus, to recover the exact photon impact position with the proper characterization of such a distribution. Every module contains 4 Application Specific Integrated Circuits (ASICs) which return detailed information of several light statistical momenta. The preliminary tests carried out on this design and controlled by means of ASICs have shown promising results towards the suitability of hybrid PET–MR systems.This work was supported by the Centre for Industrial Technological Development co-funded by FEDER through the Technology Fund (DREAM Project, IDI-20110718), the Spanish Plan Nacional de Investigacion Cientifica, Desarrollo e Innovacion Tecnologica (I + D + I) under Grant no.

Implementation and analysis of list mode algorithm using tubes of response on a dedicated brain and breast PET

In this work we present an innovative algorithm for the reconstruction of PET images based on the List-Mode (LM) technique which improves their spatial resolution compared to results obtained with current MLEM algorithms. This study appears as a part of a large project with the aim of improving diagnosis in early Alzheimer disease stages by means of a newly developed hybrid PET-MR insert. At the present, Alzheimer is the most relevant neurodegenerative disease and the best way to apply an effective treatment is its early diagnosis. The PET device will consist of several monolithic LYSO crystals coupled to SiPM detectors. Monolithic crystals can reduce scanner costs with the advantage to enable implementation of very small virtual pixels in their geometry. This is especially useful for LM reconstruction algorithms, since they do not need a pre-calculated system matrix. We have developed an LM algorithm which has been initially tested with a large aperture (186 mm) breast PET system. Such an algorithm instead of using the common lines of response, incorporates a novel calculation of tubes of response. The new approach improves the volumetric spatial resolution about a factor 2 at the border of the field of view when compared with traditionally used MLEM algorithm. Moreover, it has also shown to decrease the image noise, thus increasing the image quality. © 2012 Elsevier B.V.

Agreement between a simple dyspnea-guided treatment algorithm for stable COPD and the GOLD guidelines: A pilot study

Introduction: Guidelines recommendations for the treatment of COPD are poorly followed. This could be related to the complexity of classification and treatment algorithms. The purpose of this study was to validate a simpler dyspnea-based treatment algorithm for inhaled pharmacotherapy in stable COPD, comparing its concordance with the current Global Initiative for Obstructive Lung Disease (GOLD) guideline. Methods: We enrolled patients who had been diagnosed with COPD in three primary care facilities and two tertiary hospitals in Spain. We determined anthropometric data, forced expiratory volume in the 1st second (percent), exacerbations, and dyspnea based on the modified Medical Research Council scale. We evaluated the new algorithm based on dyspnea and exacerbations and calculated the concordance with the current GOLD recommendations. Results: We enrolled 100 patients in primary care and 150 attending specialized care in a respiratory clinic. There were differences in the sample distribution between cohorts with 41% vs 26% in grade A, 16% vs 12% in grade B, 16% vs 22% in grade C, and 27% vs 40% in grade D for primary and respiratory care, respectively (P=0.005). The coincidence of the algorithm with the GOLD recommendations in primary care was 93% and 91.8% in the respiratory care cohort. Conclusion: A simple dyspnea-based treatment algorithm for inhaled pharmacotherapy of COPD could be useful in the management of COPD patients and concurs very well with the recommended schema suggested by the GOLD initiative
