Calibration of QM-MOURA three-axis magnetometer and gradiometer

Abstract. MOURA instrument is a three-axis magnetometer and gradiometer designed and developed for Mars MetNet Precursor mission. The initial scientific goal of the instrument is to measure the local magnetic field in the surroundings of the lander i.e. to characterize the magnetic environment generated by the remanent magnetization of the crust and the superimposed daily variations of the field produced either by the solar wind incidence or by the thermomagnetic variations. Therefore, the qualification model (QM) will be tested in representative scenarios like magnetic surveys on terrestrial analogues of Mars and monitoring solar events, with the aim to achieve some experience prior to the arrival to Mars. In this work, we present a practical first approach for calibration of the instrument in the laboratory; a finer correction after the comparison of MOURA data with those of a reference magnetometer located in San Pablo de los Montes (SPT) INTERMAGNET Observatory; and a comparative recording of a geomagnetic storm as a demonstration of the compliance of the instrument capabilities with the scientific objectives

Acoustic estimation of abundance and distribution of anchovy in the NW Mediterranean

In order to estimate the abundance and the distribution of the anchovy in the Northwest Mediterranean, a standardised series of acoustic evaluation cruises was carried out in 1990, 1991, 1992, 1993 and 1995. The series showed that there was agreement between the biomass estimations and the registered landings in the area. On the other hand, some areas were identified where the recruits were largely localisedESTIMACIÓN ACÚSTICA DE LA ABUNDANCIA Y DISTRIBUCIÓN DE ANCHOA EN EL NOROESTE MEDITERRÁNEO.

Volatile composition of wines elaborated from organic and non-organic grapes

The aim of this work was to study the evolution of volatile compounds during the alcoholic fermentation of organic and non-organic grapes. To do this, grapes were cultivated using organic and non-organic grapes; their tasting showed some differences between both types of Monastrell grapes. Throughout the alcoholic fermentation, the samples of organic grapes had higher concentration of total alcohols but lower concentration of esters and acids than the samples of conventional ones. Therefore, the volatile composition of wines from two different cultivated grapes using both agronomic practices was different. Moreover, regarding to the volatile compounds that contributed directly to wine aroma, generally organic wine had more chemicals and floral aromas, while the wines from conventional practices had more fruity aromas. Principal component analysis (PCA) showed that it is possible to differentiate between both types of wines in terms of concentration of volatile compounds formed during the alcoholic fermentation. Consequently, agronomic practices affected the grape taste, the wine volatile composition and its quality.Peer Reviewe

Sources of hepatic triglyceride accumulation during high-fat feeding in the healthy rat

Hepatic triglyceride (HTG) accumulation from peripheral dietary sources and from endogenous de novo lipogenesis (DNL) was quantified in adult Sprague-Dawley rats by combining in vivo localized 1H MRS measurement of total hepatic lipid with a novel ex vivo 2H NMR analysis of HTG 2H enrichment from 2H-enriched body water. The methodology for DNL determination needs further validation against standard methodologies. To examine the effect of a high-fat diet on HTG concentrations and sources, animals (n = 5) were given high-fat chow for 35 days. HTG accumulation, measured by in vivo 1H MRS, increased significantly after 1 week (3.85 ± 0.60% vs 2.13 ± 0.34% for animals fed on a standard chow diet, P < 0.05) and was maintained until week 5 (3.30 ± 0.60% vs 1.12 ± 0.30%, P < 0.05). Animals fed on a high-fat diet were glucose intolerant (13.3 ± 1.3 vs 9.4 ± 0.8 mM in animals fed on a standard chow diet, for 60 min glycemia after glucose challenge, P < 0.05). In control animals, DNL accounted for 10.9 ± 1.0% of HTG, whereas in animals given the high-fat diet, the DNL contribution was significantly reduced to 1.0 ± 0.2% (P < 0.01 relative to controls). In a separate study to determine the response of HTG to weaning from a high-fat diet, animals with raised HTG (3.33 ± 0.51%) after 7days of a high-fat diet reverted to basal HTG concentrations (0.76 ± 0.06%) after an additional 7 days of weaning on a standard chow diet. These studies show that, in healthy rats, HTG concentrations are acutely influenced by dietary lipid concentrations. Although the DNL contribution to HTG content is suppressed by a high-fat diet in adult Sprague-Dawley rats, this effect is insufficient to prevent overall increases in HTG concentrations.

Manejo anestésico para una cesárea en paciente con enfermedad de Charcot–Marie–Tooth - 1ª Parte

Exponemos el caso de una paciente diagnosticada de enfermedad de Charcot-Marie-Tooth (ECMT) en la infancia, que es programada para cesárea electiva. La ECMT es una enfermedad hereditaria autosómica dominante, cursa con una neuropatía motora y sensorial de evolución lenta y progresiva. Se estima que su incidencia es de 1:10.000 en la población. Clínicamente se caracteriza por afectar a las extremidades inferiores, causando debilidad y atrofia muscular con deformidades importantes del pie. La neuropatía sensorial produce el desgaste y la pérdida temprana de los reflejos tendinosos profundos. En muchos casos, hay un componente sensorial que resulta en una pérdida de sensación (calor, frío y dolor). Los estadios avanzados de la enfermedad se caracterizan por pérdida de la sensibilidad con distribución en guante. Los síntomas clínicos y su progresión ocasionan un deterioro de la regulación de la temperatura corporal y la ausencia de sudoración

Total Absorption Spectroscopy Study of 92^{92}Rb Decay: A Major Contributor to Reactor Antineutrino Spectrum Shape

The antineutrino spectra measured in recent experiments at reactors are inconsistent with calculations based on the conversion of integral beta spectra recorded at the ILL reactor. $^{92}$Rb makes the dominant contribution to the reactor spectrum in the 5-8 MeV range but its decay properties are in question. We have studied $^{92}$Rb decay with total absorption spectroscopy. Previously unobserved beta feeding was seen in the 4.5-5.5 region and the GS to GS feeding was found to be 87.5(25)%. The impact on the reactor antineutrino spectra calculated with the summation method is shown and discussed.Comment: 6 pages, 3 figure

Nature-based strategies to regenerate the functioning and biodiversity of vineyards

16 páginas.- 2 figuras.- 1 Box.- 138 referenciasGrapevine is one of the most important perennial fruit crops worldwide. Historically, vineyards were compatible with soil conservation practices and multitrophic biodiversity, but vineyards are now generally eroded and biologically impoverished, making them more susceptible to pests and diseases. However, the idiosyncrasy of the wine sector places wine growers in a unique position to lead the adoption of a range of sustainable management strategies and, thus, to pioneer a wider transformation of the agricultural sector. In this article, we provide an overview of nature-based management strategies that may be used for the regeneration of the functioning and biodiversity of vineyards and that may also lead to improved plant nutrition, grape berry quality and the suppression of pathogens and pests. These strategies include the use of microbial and nonmicrobial biostimulants, fertilization with organic amendments as well as foliar fertilization with nature-based products, the use of cover crops and the reintegration of livestock in vineyards, especially sheep. We will also pay special attention to the implementation of circular economy in the vineyard in relation to the previously mentioned management strategies and will also discuss the importance of considering all these aspects from a holistic and integrative perspective, rather than taking them into account as single factors. Assuming the integral role of soils in the functioning of agroecosystems, soils will be considered transversally across all sections. Finally, we will argue that the time is now ripe for innovation from the public and private sectors to contribute to the sustainable management of vineyards while maintaining, or even improving, the profit margin for farmers and winemakers.This review article is, in part, the result of a workshop (I Jornadas ‘Suelos Vivos’ para la regeneración de la vida en suelos de viñedos gaditanos; https://suelosvivos.es/i-jornadas-suelos-vivos/) carried out within the context of the ‘Suelos Vivos’ Regional Operational Group of the EIP-Agri, which was celebrated between 23 and 24 March 2023 in Puerto Real, Cádiz.
