Cycles inside cycles: Spanish regional aggregation

This paper sets out a comprehensive framework to identify regional business cycles within Spain and analyses their stylised features and the degree of synchronization present among them and the Spanish economy. We show that the regional cycles are quite heterogeneous although they display some degree of synchronization that can be partially explained using macroeconomic variables. We also propose a dynamic factor model to cluster the regional comovements and Önd out if the country cycle is simply the aggregation of the regional ones. We Önd that the Spanish business cycle is not shared by the seventeen regions, but is the sum of the di§erent regional behaviours. The implications derived from our results are useful both for policy makers and analysts.

Production of prickly pear (Opuntia ficus-indica) vinegar in submerged culture using Acetobacter malorum and Gluconobacter oxydans: Study of volatile and polyphenolic composition

Prickly pear (Opuntia ficus-indica (L). Mill.) vinegar has been produced by submerged culture using scale laboratory fermenters at three acetification temperatures (30 ◦C, 37 ◦C, and 40 ◦C). Pure thermotolerant Acetic Acid Bacteria (AAB) which had been previously submitted to molecular identification by PCR–RFLP of the 16S–23S rDNA regions and 16S–23S ITS rDNA sequencing, were used. The AAB used were identified as Acetobacter malorum and Gluconobacter oxydans. The acetic fermentation achieved by A. malorum at 30 ◦C and 37 ◦C was more efficient, in terms of acidity, than that accomplished by G. oxydans. The chemical analysis revealed the presence of 85 individual volatile compounds and 17 polyphenolic compounds. The concentration of approximately half the volatile compounds was significantly affected by fermentation temperature, with clearly lower concentrations as temperature increased, whereas few significant differences were observed when comparing the vinegars produced by the two AAB species. Regarding phenolic compounds, significant increases were registered when temperature changed from 30 ◦C to 40 ◦C. Furthermore, the vinegars produced by A. malorum presented a greater concentration of phenolic compounds than those produced by G. oxydans

Thermotolerant acetic acid bacteria in the production of a red wine vinegar by surface culture at different temperatures: volatile and polyphenolic composition

This work aims to determine the effect on the aromatic profile and phenolic content of red wine vinegars produced by surface culture at two different temperatures (30 °C and 37 °C) and using different inocula of acetic acid bacteria (Acetobacter malorum, Gluconobacter oxydans and a mixture of bacteria isolated from a Sherry vinegar). Fifty-seven volatile compounds and 23 polyphenolic and furfural compounds were identified. Vinegars obtained at 37 °C had poorer volatile profiles, with no significant influence of the strain of acetic bacteria. For polyphenolic content, temperature was also the most significant variable, so that the vinegars produced at higher temperatures had lower total anthocyanin contents, while no clear trend was observed regarding the influence of temperature on the low-molecular-weight phenolic constituents. The total tannin content in the vinegars obtained experienced slight increases after acetification, although this was not affected by temperature, and it was observed that when using the mixture of acetic acid bacteria from the Sherry vinegar, the total tannin content was significantly higher than when individual bacteria cultures of Acetobacter malorum or Gluconobacter oxydans were used. Temperature appears as a key parameter for the volatile and phenolic composition of red wine vinegar versus the use of different acetic acid bacteria

First high resolution measurement of neutron capture resonances in 176Yb at the n_TOF CERN facility

Lu-177 is a versatile radioisotope used for therapy and diagnosis (theranostics) of cancer with good success in neuroendocrine tumours that is being studied to be applied to a wider range of tumours. Lu-177 is produced in few nuclear reactors mainly by the neutron capture on Lu-176. However, it could be produced at high -intensity accelerator-based neutron facilities. The energy of the neutrons in accelerator-based neutron facilities is higher than in thermal reactors. Thus, experimental data on the Yb-176(n,(sic)) cross-section in the eV and keV region are mandatory to calculate accurately the production of Yb-177, which beta decays to 177Lu. At present, there are not experimental data available from thermal to 3 keV of the Yb-176(n,(sic)) cross-section. In addition, there is no data in the resolved resonance region (RRR). This contribution shows the first results of the Yb-176 capture measurement performed at the n_TOF facility at CERN.Instituto de Salud Carlos III Spanish Government PID2020-117969RB-I00Junta de Andalucía P20-00665, B-FQM-15-6UGR2

Neutron capture and total cross-section measurements on 94,95,96Mo at n_TOF and GELINA

This work was supported by the EUFRAT open-access project of the JRC Geel and received funding from the Euratom research and training programme 2014-2018 under grant agreement No 847594 (ARIEL).Capture and total cross section measurements for 94'95'96 MO have been performed at the neutron time -of-flight facilities, n_TOF at CERN and GELINA at JRC-Geel. The measurements were performed using isotopically enriched samples with an enrichment above 95% for each of the (94'95'96)M0 isotopes. The capture measurements were performed at n_TOF using C6D6 detectors and a new sTED detector. The transmission measurements were performed at a 10 m station of GELINA using a Li-6 glass neutron detector. Preliminary results of these measurements are presented.EUFRAT open-access project of the JRC GeelEuratom 84759

The n_TOF NEAR Station Commissioning and first physics case

The NEAR Station is a new experimental area developed at the n_TOF Facility at CERN. The activation station of NEAR underwent a characterization of the beam following the installation of the new n_TOF Spallation Target. The commissioning of the neutron beam comprises a set of simulations made with the FLUKA code and experimental verification. The experimental determination of the neutron spectrum was made using activation techniques with three separate set-ups. Two set-ups were based on the Multi-foil Activation technique (MAM-1 and MAM-2), and the third set-up relied on the process of neutron moderation and activation of a single material (ANTILoPE). The three set-ups are presented. Also the present plans and future perspectives of the activation station of NEAR are discussed

Characterisation of the n_TOF 20 m beam line at CERN with the new spallation target

The n_TOF facility hosts CERN's pulsed neutron source, comprising two beam lines of different flight paths and one activation station. It is based on a proton beam delivered by the PS accelerator impinging on a lead spallation target. During Long Shutdown 2 (LS2) at CERN (2019-2021), a major upgrade of the spallation target was carried out in order to optimize the performances of the neutron beam. Therefore, the characteristics of n_TOF two experimental areas were investigated in detail. In this work, the focus is on the second experimental area (EAR2), located 20 m above the spallation target. Preliminary results of the neutron energy distribution and beam line energy resolution are presented, compared to previous experimental campaigns and Monte Carlo simulations with the FLUKA code. Moreover, preliminary results of the spatial beam profile measurements are shown
