Producción, manejo, valoración, consumo y atributos de calidad de carne vacuna argentina: estudio mediante encuestas a carniceros

El sector productivo de carne vacuna crece y las características en el consumo cambian. Los aspectos que se tienen en cuenta al momento de comprar son variados, como también las condiciones y manejos en los locales de venta. Conocer características y observaciones en carniceros barriales, intermediarios entre el frigorífico y el consumidor, permitirá conocer este eslabón clave en la venta de carne vacuna en Argentina. El presente trabajo planteó como objetivo estudiar aspectos vinculados a la producción, manejo, valoración, consumo y atributos de calidad de la carne vacuna mediante encuesta a carniceros barriales. Sesenta carniceros, considerando todas las zonas de la ciudad de Tandil, fueron entrevistados personalmente. El análisis de conglomerados permitió observar dos agrupamientos: CON-1(3-zonas) y CON-2(4-zonas). Mayoritariamente no se hallaron diferencias entre los vendedores en los aspectos de producción y manejo. Una diferencia significativa fue observada en la frecuencia de compra de las medias reses. Asimismo, todos indicaron poseer cámara fría, pero rechazaron posibles atributos de maduración. En relación con el consumo y atributos de calidad, se destacó el color como factor ?frescura? y preferencia de sus productos por higiene-sanidad, calidad y confianza. La presencia de la grasa intramuscular mostró diferencias significativas; en CON-1, el 80 % de sus clientes prefiere cortes con marmoleo, mientras que en CON-2, el 96 % elige cortes magros. Todos manifestaron observar cambios en los hábitos y volumen de compra en los últimos años. A la luz de los resultados, será necesario continuar con el trabajo de investigación interdisciplinar, para comprender y lograr mejoras considerando los aspectos socioeconómicos y tecnológicos de la calidad de la carne vacuna.The productive beef sector grows, and consumption traits change. The aspects considered at the time of purchase varied, as well as the conditions and handling in the sale points. Knowing the features and observations of neighborhood butchers, intermediaries between the cold storage and the consumer, will allow knowing this critical link in the beef sale in Argentina. The aim of this work was to study aspects related to the production, handling, assessment, consumption, and quality attributes of beef through a survey of local butchers. Sixty butchers, considering all areas of the city of Tandil, were personally interviewed. The cluster analysis allowed observing two groupings: CON-1(3-zones) and CON-2(4-zones). Mainly, no differences were found between sellers in production and management aspects. A significant difference was observed in the purchase frequency of half cattle carcasses. Likewise, all indicated having a cooling room, but rejected possible beef-maturation attributes. In relation to consumption and quality attributes, the color was highlighted as a "freshness" factor and preference of their products considering hygiene-sanitation, quality, and trust. The presence of intramuscular fat showed significant differences; in CON-1, 80 % of their clients prefercuts with marbling, while in CON-2, 96 % choose lean cuts. All stated observing changes in purchasing habits and volume in recent years. In light of the results, it will be necessary to continue with interdisciplinary research work, to understand and achieve improvements considering the socio-economic and technological beef quality aspects.Fil: Cáffaro Tommasiello, Estefanía Milagros.

Efficacy and safety of a double-coated paclitaxel-eluting coronary stent: The EUCATAX trial

Objectives: The aim of this study was the comparison of a new double-coated paclitaxel-eluting coronary stent with bare-metal stent (BMS) in patients undergoing percutaneous coronary intervention. Background: Stent coating with biodegradable polymers as a platform for elution of drugs has the potential for complete elution of drugs and for decreasing the risk of late complications. Methods: Multicenter randomized trial comparing a paclitaxel-eluting stent (PES) coated with a biodegradable polymer and glycocalyx with the equivalent BMS. We randomly assigned 422 patients with de novo coronary lesions to PES (211 patients) or to BMS (211 patients). Primary end point was target vessel failure (TVF) defined as cardiac death, myocardial infarction, and target vessel revascularization. Clinical secondary end points were target vessel revascularization, target lesion revascularization, stent thrombosis (ST), and major adverse cardiovascular events (MACE). Angiographic secondary end points were late loss and binary restenosis. Results: At 1 year of follow-up, TVF rate was 9.5% in the PES group and 17.1% in the BMS group (P = 0.02), and MACE rate was 10% in PES and 19% in BMS arm (P = 0.009). All other secondary end points were reached but ST. ST rate was low and similar in both study arms. Conclusions: The study shows that patients treated with PES with dual coating technology had significantly lower incidence of TVF and MACE than those treated with BMS design; however, longer follow-up should be necessary to assess true advantages of this technology compared with the previous one.Fil: Rodriguez, Alfredo E..

Azimuthal anisotropy of charged jet production in root s(NN)=2.76 TeV Pb-Pb collisions

We present measurements of the azimuthal dependence of charged jet production in central and semi-central root s(NN) = 2.76 TeV Pb-Pb collisions with respect to the second harmonic event plane, quantified as nu(ch)(2) (jet). Jet finding is performed employing the anti-k(T) algorithm with a resolution parameter R = 0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero nu(ch)(2) (jet) is observed in semi-central collisions (30-50% centrality) for 20 <p(T)(ch) (jet) <90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the nu(2) of single charged particles at high p(T). Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions.

Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe

Pseudorapidity and transverse-momentum distributions of charged particles in proton-proton collisions at root s=13 TeV

The pseudorapidity (eta) and transverse-momentum (p(T)) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy root s = 13 TeV. The pseudorapidity distribution in vertical bar eta vertical bar <1.8 is reported for inelastic events and for events with at least one charged particle in vertical bar eta vertical bar <1. The pseudorapidity density of charged particles produced in the pseudorapidity region vertical bar eta vertical bar <0.5 is 5.31 +/- 0.18 and 6.46 +/- 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 <p(T) <20 GeV/c and vertical bar eta vertical bar <0.8 for events with at least one charged particle in vertical bar eta vertical bar <1. The evolution of the transverse momentum spectra of charged particles is also investigated as a function of event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators. (C) 2015 CERN for the benefit of the ALICE Collaboration. Published by Elsevier B.V.

Elliptic flow of muons from heavy-flavour hadron decays at forward rapidity in Pb-Pb collisions at root s(NN)=2.76TeV

The elliptic flow, v(2), of muons from heavy-flavour hadron decays at forward rapidity (2.5 <y <4) is measured in Pb-Pb collisions at root s(NN)= 2.76TeVwith the ALICE detector at the LHC. The scalar product, two- and four-particle Q cumulants and Lee-Yang zeros methods are used. The dependence of the v(2) of muons from heavy-flavour hadron decays on the collision centrality, in the range 0-40%, and on transverse momentum, p(T), is studied in the interval 3 <p(T)<10 GeV/c. A positive v(2) is observed with the scalar product and two-particle Q cumulants in semi-central collisions (10-20% and 20-40% centrality classes) for the p(T) interval from 3 to about 5GeV/c with a significance larger than 3 sigma, based on the combination of statistical and systematic uncertainties. The v(2) magnitude tends to decrease towards more central collisions and with increasing pT. It becomes compatible with zero in the interval 6 <p(T)<10 GeV/c. The results are compared to models describing the interaction of heavy quarks and open heavy-flavour hadrons with the high-density medium formed in high-energy heavy-ion collisions.
