Factores que influyen en el consumo de aceite de oliva

Durante los meses de julio y agosto del año 2015 se desarrolló en la Ciudad de Bahía Blanca una encuesta piloto tendiente a obtener información acerca de las elecciones de consumo respecto al aceite de oliva, con especial énfasis en el producido en el Sudoeste Bonaerense. Se entrevistaron a 175 individuos, mayores de 18 años, interceptados en super/hipermercados y en otros comercios dedicados a la venta de alimentos. El relevamiento comprendió diferentes barrios a fin de asegurar la representatividad geográfica y de cubrir diversas realidades socio-económicas. El trabajo contiene una introducción que se refiere a la evolución de la actividad olivícola en los últimos tiempos y que resalta las propiedades del aceite de oliva como alimento saludable; el marco conceptual y los antecedentes empíricos que sustentan el estudio, en base a los conceptos de “calidad percibida” y de atributos y los resultados descriptivos obtenidos. Entre estos últimos, es posible indicar que hay diferencias según el producto en cuestión sea o no el principal aceite comestible que se use en el hogar, con pautas de consumo y características demográficas y socio-económicas distintivas. Como reflexión final, es posible señalar la necesidad de diseñar una estrategia de mercado, por parte de todos los actores involucrados, tendiente a captar a consumidores de aceite de oliva producido en la Región, poniendo a disposición información al respect

A responsabilidade dos administradores na insolvência

The subject of insolvency assumes great relevance in the Portuguese society. In our country, a high number of companies ends up in ruin. One of the causes of this problem is the irresponsible behaviour of our companies’ administrators that jeopardize their survival. We have to face with the need to see how and to what extent the administrators that cause the insolvency situation or make it worse can be held responsible for it. In order to answer this question, we will analyse the entire regime of the accountability of the administrators present in the CIRE, as well as the interconnections, which proved to be necessary, to make between this diploma and the CSC.O tema da insolvência assume grande relevância na sociedade portuguesa. No nosso país um elevado número de empresas acaba em ruína. Uma das causas deste problema é a adoção, pelos administradores das nossas empresas, de comportamentos que colocam em risco a sobrevivência das mesmas. É assim que nos confrontamos com a necessidade de descortinar como e em que medida é que os administradores que causem ou agravem a situação de insolvência podem por ela ser responsabilizados. De modo a dar resposta a esta questão iremos analisar todo o regime da responsabilização dos administradores presente no CIRE, bem como as interligações que demonstrarem ser necessárias efetuar entre este diploma e o CSC

Caracterización de los consumidores de aceite de oliva de la ciudad de Bahía Blanca. Una aproximación

A fin de realizar una primera caracterización del consumidor de aceite de oliva residente en la Ciudad de Bahía Blanca, se analizan datos provenientes de una encuesta piloto, relevada durante los meses de julio y de agosto del año 2015. En la misma, se indagó acerca de las preferencias y de las elecciones del producto, con especial énfasis en el elaborado en el Sudoeste Bonaerense. El estudio llevado a cabo es descriptivo, exploratorio, multivariado y permite señalar como principales resultados: la percepción del aceite de oliva como beneficioso para la salud, la valoración del atributo "sabor", la importancia de la educación y el desconocimiento sobre los diferentes tipos y la zona de origen. Asimismo, es posible identificar dos grupos de consumidores, según el producto sea o no el principal aceite comestible del hogar, con modalidades de consumo y de compra y aspectos demográficos y socio-económicos distintivos. Como reflexión final, es de destacar la necesidad de diseñar una estrategia de mercado, tendiente a captar consumidores de aceite de oliva regional, poniendo a disposición información respecto a su calidad, la que se corresponde con altos estándares internacionales.Fil: Lupín, Beatriz.

First approaches for the transplantation of hepatocytes from Wistar rat preneoplastic livers into healthy recipients

Background: the shortage of donors of hepatocyte transplantation therapy led to the use of so-called marginal donors. Some donors may have a hepatic illnesses that is associated with hepatic preneoplasia with foci of altered hepatocytes (FAH). Aims: to determine whether recipients developed FAH upon transplantation with hepatocytes from a preneoplastic liver and whether FAH progresses to a preneoplastic hepatocyte- derived tumor (PHDT), up to 60 days after transplantation. Material and methods: male Wistar adult rats were used as donors and recipients. Donors underwent a 2-phase model of liver preneoplasia for hepatocyte isolation. Recipients underwent a partial two thirds hepatectomy and received 150,000 hepatocytes. Recipients were euthanized seven and 60 days after transplantation. The number of FAH per liver area, percentage of liver occupied by FAH, the hepatic enzymatic profile, the percentage of prothrombin time (PT), the proliferative index (PI) and liver morphology were analyzed. Results: recipients developed few and very isolated FAH. No statistical differences were found between hepatic enzyme activities and PT. There were no differences between the groups with regard to the number of FAH per liver area and percentage of liver occupied by FAH after 60 days. The PI decreased on day 60 compared to day seven. No morphological alterations were found. Conclusions: recipients developed few FAH that did not increase in number or size, nor did they progress to PHDT and had normal plasma biochemical features and liver morphology up to 60 days post-transplant. Additional studies are needed to determine whether FAH development constitutes a risk for recipients while waiting for whole organ transplant.Fil: Vera, Marina Cecilia.

Such survey inquired about the preferences and choices of the product, with special emphasis on the manufactured in the southwest of Buenos Aires province. The conducted study is descriptive, exploratory, multivariate, and allows identifying the following main results: the perception of olive oil as beneficial to health, the valuation of the flavor attribute, the importance of education, and the lack of awareness about the different types and the region-of-origin. Also, it is possible to distinguish two consumer groups, depending on whether or not the product is the main consumable oil at home, with distinctive consumption and purchasing modalities, as well as demographic and socio-economic aspects. As a final conclusion, it is worth to highlight the need to design a marketing strategy aimed to capture consumers of regional olive oil, making available information about its quality, which corresponds to high international standards

Epidemiologia molecular de um surto de bacteriemia por Enterobacter cloacae e Enterobacter agglomerans ocorrido na região de Campinas, São Paulo, Brasil

A total of 73 isolates (57 Enterobacter cloacae and 16 Enterobacter agglomerans), recovered during an outbreak of bacteremia in the Campinas area, São Paulo, Brazil, were studied. Of these isolates, 61 were from parenteral nutrition solutions, 9 from blood cultures, 2 from a sealed bottle of parenteral nutrition solution, and one was of unknown origin. Of the 57 E. cloacae isolates, 54 were biotype 26, two were biotype 66 and one was non-typable. Of 39 E. cloacae isolates submitted to ribotyping, 87.2% showed the same banding pattern after cleavage with EcoRI and BamHI. No important differences were observed in the antimicrobial susceptibility patterns among E. cloacae isolates exhibiting the same biotype, serotype and ribotype. All E. agglomerans isolates, irrespective of their origin, showed same patterns when cleaved with EcoRI and BamHI. The results of this investigation suggest an intrinsic contamination of parenteral nutrition solutions and incriminate these products as a vehicle of infection in this outbreak.Foram estudadas um total de 73 cepas (57 de E. cloacae e 16 E. agglomerans), isoladas durante um surto de bacteriemia ocorrido na região de Campinas, S. Paulo. Entre estas cepas, 61 foram isoladas de solução de nutrição parenteral, 9 de sangue, 2 de bolsa fechada de solução de nutrição parenteral e uma era de origem desconhecida. Entre as 57 cepas de E. cloacae, a maioria das cepas foram do biotipo 26/sorotipo O3 (39 cepas) e do biotipo 26/OR (13). Entre as 39 cepas de E. cloacae ribotipadas, 87,2% apresentaram o mesmo padrão de bandas com EcoRI e BamHI. Cepas de E. cloacae pertencentes ao mesmo biotipo, sorotipo e ribotipo não apresentaram diferenças significativas em relação ao padrão de sensibilidade aos agentes antimicrobianos. Todas as cepas de E. agglomerans, independente da origem, pertenciam ao mesmo ribotipo após a clivagem com EcoRI e BamHI. Os resultados obtidos sugerem uma contaminação intrínseca das soluções de nutrição parenteral, incriminando-as como o veículo de transmissão dos agentes etiológicos do surto

The 13th Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-IV Survey Mapping Nearby Galaxies at Apache Point Observatory

The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) began observations in July 2014. It pursues three core programs: APOGEE-2,MaNGA, and eBOSS. In addition, eBOSS contains two major subprograms: TDSS and SPIDERS. This paper describes the first data release from SDSS-IV, Data Release 13 (DR13), which contains new data, reanalysis of existing data sets and, like all SDSS data releases, is inclusive of previously released data. DR13 makes publicly available 1390 spatially resolved integral field unit observations of nearby galaxies from MaNGA,the first data released from this survey. It includes new observations from eBOSS, completing SEQUELS. In addition to targeting galaxies and quasars, SEQUELS also targeted variability-selected objects from TDSS and X-ray selected objects from SPIDERS. DR13 includes new reductions ofthe SDSS-III BOSS data, improving the spectrophotometric calibration and redshift classification. DR13 releases new reductions of the APOGEE-1data from SDSS-III, with abundances of elements not previously included and improved stellar parameters for dwarf stars and cooler stars. For the SDSS imaging data, DR13 provides new, more robust and precise photometric calibrations. Several value-added catalogs are being released in tandem with DR13, in particular target catalogs relevant for eBOSS, TDSS, and SPIDERS, and an updated red-clump catalog for APOGEE.This paper describes the location and format of the data now publicly available, as well as providing references to the important technical papers that describe the targeting, observing, and data reduction. The SDSS website, http://www.sdss.org, provides links to the data, tutorials and examples of data access, and extensive documentation of the reduction and analysis procedures. DR13 is the first of a scheduled set that will contain new data and analyses from the planned ~6-year operations of SDSS-IV.PostprintPeer reviewe

Multidifferential study of identified charged hadron distributions in ZZ-tagged jets in proton-proton collisions at s=\sqrt{s}=13 TeV

Jet fragmentation functions are measured for the first time in proton-proton collisions for charged pions, kaons, and protons within jets recoiling against a $Z$ boson. The charged-hadron distributions are studied longitudinally and transversely to the jet direction for jets with transverse momentum 20 $< p_{\textrm{T}} < 100$ GeV and in the pseudorapidity range $2.5 < \eta < 4$. The data sample was collected with the LHCb experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 1.64 fb$^{-1}$. Triple differential distributions as a function of the hadron longitudinal momentum fraction, hadron transverse momentum, and jet transverse momentum are also measured for the first time. This helps constrain transverse-momentum-dependent fragmentation functions. Differences in the shapes and magnitudes of the measured distributions for the different hadron species provide insights into the hadronization process for jets predominantly initiated by light quarks.Comment: All figures and tables, along with machine-readable versions and any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-013.html (LHCb public pages

Study of the B−→Λc+Λˉc−K−B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-} decay

The decay $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ is studied in proton-proton collisions at a center-of-mass energy of $\sqrt{s}=13$ TeV using data corresponding to an integrated luminosity of 5 $\mathrm{fb}^{-1}$ collected by the LHCb experiment. In the $\Lambda_{c}^+ K^{-}$ system, the $\Xi_{c}(2930)^{0}$ state observed at the BaBar and Belle experiments is resolved into two narrower states, $\Xi_{c}(2923)^{0}$ and $\Xi_{c}(2939)^{0}$, whose masses and widths are measured to be $$m(\Xi_{c}(2923)^{0}) = 2924.5 \pm 0.4 \pm 1.1 \,\mathrm{MeV}, \\ m(\Xi_{c}(2939)^{0}) = 2938.5 \pm 0.9 \pm 2.3 \,\mathrm{MeV}, \\ \Gamma(\Xi_{c}(2923)^{0}) = \phantom{000}4.8 \pm 0.9 \pm 1.5 \,\mathrm{MeV},\\ \Gamma(\Xi_{c}(2939)^{0}) = \phantom{00}11.0 \pm 1.9 \pm 7.5 \,\mathrm{MeV},$$ where the first uncertainties are statistical and the second systematic. The results are consistent with a previous LHCb measurement using a prompt $\Lambda_{c}^{+} K^{-}$ sample. Evidence of a new $\Xi_{c}(2880)^{0}$ state is found with a local significance of $3.8\,\sigma$, whose mass and width are measured to be $2881.8 \pm 3.1 \pm 8.5\,\mathrm{MeV}$ and $12.4 \pm 5.3 \pm 5.8 \,\mathrm{MeV}$, respectively. In addition, evidence of a new decay mode $\Xi_{c}(2790)^{0} \to \Lambda_{c}^{+} K^{-}$ is found with a significance of $3.7\,\sigma$. The relative branching fraction of $B^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-}$ with respect to the $B^{-} \to D^{+} D^{-} K^{-}$ decay is measured to be $2.36 \pm 0.11 \pm 0.22 \pm 0.25$, where the first uncertainty is statistical, the second systematic and the third originates from the branching fractions of charm hadron decays.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-028.html (LHCb public pages
