Acceptability of yacon flakes (Smallanthus sonchifolia) for dietary use with inulin
"This study aimed to elaborate on yacon flakes and determine the proximal composition of
fresh yacon and final flakes, made at different temperatures (120°C, 150°C and 180°C) for
20 mins. We measured the acceptability of the sensory attributes: taste, texture, odour and
colour and the global acceptability at the laboratory level, using semi-trained panellists
and an unstructured hedonic scale. The acceptability of the flakes was measured at
different temperatures. Our results indicate that the flakes made at 180°C had the highest
acceptance (87%), and the flakes made at 120°C had 80% of unacceptability. Our data
were analysed according to the analysis of variance (ANOVA) and Tukey's test. We found
significant differences between the averages of the taste scores (T0:7.1; T1:7.6; T2:6.7;
T3:4.6), p<0.05; texture (T0:7.1; T1:7.2; T2:5.7; T3:4.5), p<0.05; and odour (T0:7.2;
T1:7.6; T2:5.1; T3:3.3), p<0.05. The amount of fructooligosaccharides on a fresh basis
was Ⱦ±SD (31.60±0.650) and on a dry basis (37.44±1DS). Microbiological analysis
shows that the flakes are fit for human consumption. It is concluded that yacon flakes
contain significant amounts of inulin, being a good substitute alternative for the
preparation of snack-type dietetic products
Intragranitic locle golcl cleposits in the Tomiño area (Ponteveclra)
[Resumen] En este trabajo se describen las principales características de las mineralizaciones auríferas filonianas que aparecen en varios cuerpos graníticos sintectónicos en el área de Tomillo (SW de la provincia de Pontevedra), haciendo también referencia al contexto geológico en el que dichas mineralizaciones se presentan. Se trata de venas y filones de cuarzo con sulfuros (pirita, arsenopirita y calcopirita principalmente), con greisenización asociada, originados como consecuencia de un proceso neumatolítico-hidrotermal controlado por el sistema de fracturas de los granitos encajantes. Pueden diferenciarse cinco paragénesis consecutivas: postmagmática, de endogreisen, hidrotermal temprana, hidrotermal tardía y supergénica. El oro se presenta en forma de inclusiones microscópicas dentro de los sulfuros (principalmente en la calcopirita), que van aumentando en tamaño y proporciór a lo largo de las etapas sucesivas del proceso de mineralización.[Abstract] The main characteristics of lode gold deposits ocurring in sorne syntectonic granitic bodies in the Tomiño Area (SW of Pontevedra province) are described in this work. The geological context of this mineralization type is also referred to. The mineralizations consist of quartz-veins bearing sulphides (mainly pyrite, arsenopyrite and chalcopyrite), with associated greisenization in the wallrock, produced by a pneumatolytic-hydrothermal process that is controlled by the fracture system in the host granites. Five consecutive paragenesis can be distinguished: postmagmatic, endogreisen, early hydrothermal, late hydrothermal and supergene.

Gradual transition from insulator to semimetal of CaEuB with increasing Eu concentration
The local environment of Eu (, ) in
CaEuB () is investigated by
means of electron spin resonance (ESR). For the spectra show
resolved \textit{fine} and \textit{hyperfine} structures due to the cubic
crystal \textit{electric} field and nuclear \textit{hyperfine} field,
respectively. The resonances have Lorentzian line shape, indicating an
\textit{insulating} environment for the Eu ions. For , as increases, the ESR lines broaden due to local
distortions caused by the Eu/Ca ions substitution. For , the lines broaden further and the spectra gradually change from
Lorentzian to Dysonian resonances, suggesting a coexistence of both
\textit{insulating} and \textit{metallic} environments for the Eu ions.
In contrast to CaGdB, the \textit{fine} structure is still
observable up to . For the \textit{fine} and
\textit{hyperfine} structures are no longer observed, the line width increases,
and the line shape is purely Dysonian anticipating the \textit{semimetallic}
character of EuB. This broadening is attributed to a spin-flip scattering
relaxation process due to the exchange interaction between conduction and
Eu electrons. High field ESR measurements for
reveal smaller and anisotropic line widths, which are attributed to magnetic
polarons and Fermi surface effects, respectively.Comment: Submitted to PR
Microscopic evidence for field-induced magnetism in CeCoIn
We present NMR data in the normal and superconducting states of CeCoIn
for fields close to T in the plane. Recent
experiments identified a first-order transition from the normal to
superconducting state for T, and a new thermodynamic phase below 290
mK within the superconducting state. We find that the Knight shifts of the
In(1), In(2) and the Co are discontinuous across the first-order transition and
the magnetic linewidths increase dramatically. The broadening differs for the
three sites, unlike the expectation for an Abrikosov vortex lattice, and
suggests the presence of static spin moments in the vortex cores. In the
low-temperature and high-field phase the broad NMR lineshapes suggest ordered
local moments, rather than a long wavelength quasiparticle spin density
modulation expected for an FFLO phase.Comment: 4 pages, 4 figures. to appear in Phys. Rev. Let
Visual acuity and olfatory sensitivity in the swordfish (Xiphias gladius) for the detection of prey during field experiments using the surface longline gear with different bait types
During a total of 20 sets carried out on board a surface longliner, the different degrees of
effectiveness obtained in the capture of swordfish were evaluated using 5 different bait types
(natural, artificial and mixed). The results point to substantial and significant differences in the
CPUEs obtained among the different bait types tested to catch swordfish. However, the results
show few mean differences that were not statistically significant between the CPUEs obtained
using natural bait (control) or mixed bait consisting of artificial bait on the outside -which in
itself was of null effectiveness- into which was inserted a piece of natural bait, concealed from
view. Both types of bait (control and mixed) were effective in the capture of swordfish despite
the differences in constitution and properties. On the basis of these results, it is possible to make
an indirect assessment of the importance of visual and odor stimuli in the swordfish to detect
and carry out the final attack on its prey. Odor was found to be the key element in this process
Safety and effectiveness of a new electrical detachable microcoil for embolization of hemorrhoidal disease, November 2020–December 2021: results of a prospective study
Purpose: The purpose of this study was to prospectively evaluate the efficacy and safety of a new, bare platinum, detachable microcoil as a metallic embolization agent in the treatment of hemorrhoidal disease. Material and Methods: This prospective single-center study evaluated a new, bare platinum, electrical, detachable microcoil (Prestige plus coil (Balt Montmorency France)) for use in vascular embolization in patients with hemorrhoidal disease. Between January 2020 and January 2021, 24 embolization procedures were performed in 21 patients (12 males, 9 females; mean age 44.3 ± 7.3). The inclusion criteria were: (a) participants with grade I, II and III hemorrhoidal disease on the Goligher classification; (b) patients older than 18 years of age with a score of greater than 4 on the French bleeding score (FBS) scale; (c) patients with scores greater than 2 on the scale of discomfort proposed by Tradi and Farfallah. (d) patients who underwent treatment that included the use of the new novel coil (Prestige plus coil (Balt)) as an embolic material. The exclusion criteria were participants who failed to provide informed consent and participants diagnosed with rectal bleeding due to other causes (cancer, fissures or others). Participants with severe renal insufficiency, non-correctable coagulation abnormalities and adverse reactions to the contrast medium not correctable with medication were also excluded. The symptoms, technical aspects, the transarterial approach, clinical and technical success complications and short-term outcomes were assessed. Results: Technical success was obtained in 100% of the cases. Seventeen (80.9%) patients experienced improvements in their hemorrhoidal disease. The VAS and QL scores improved by 4 and 1.5 points (81.2% and 87.5%), respectively, after embolization (pV: 0001). Three (14.2%) patients underwent a second embolization due to rebleeding. One patient (4.7%) underwent surgery. No major complications were observed. Three patients had minor complications. The assessment of subjective post-treatment symptoms and QL surveys showed significant differences from the baseline survey. Likewise, the measurement of the degree of satisfaction using a telephone survey at 12 months revealed a high degree of patient satisfaction over 10 points (mean 8.3 ± 1.1). Conclusions: The present study demonstrates that the use of the new, platinum, detachable, electrical microcoil is safe and well-tolerated in the treatment of hemorrhoidal disease. Key points: Catheter-directed hemorrhoidal dearterialization (CDHD) is the procedure of embolization with embolic agents for the treatment of internal hemorrhoids. CDHD is a simple and safe procedure that is accepted by patients and preserves the anal sphincter; it presents few complications when metal devices or microspheres are used as embolic agents. As the recommended embolization agent in treatments, the Prestige electrical, detachable coil is a safe, easy-to-use and effective arterial embolic device
