Uso de harina de baya de uva en la producción de cookies

La producción de vinos y derivados produce residuo, en promedio cerca del 20% de la uva, en peso, constituido por la cáscara o la película, las semillas y los restos de la pulpa de la uva, siendo el resultado del aplastamiento del grano. Por eso la producción de harina a partir de la baya de uva surge como una alternativa para minimizar el residuo generado del proceso de vinificación. Las galletas son productos que se pueden obtener a través de diversos procesos, se consideran uno de los alimentos más populares y de mayor consumo. El presente estudio consistió en la elaboración de una harina a partir del aprovechamiento de un residuo agroindustrial de la actividad vitivinícola, la baya de uva, que fue empleado en el desarrollo de cookies. La harina presentó características físico-químicas dentro de los estándares establecidos por la legislación. A través de la evaluación sensorial obtuvimos resultados que evidencian la aceptación de las galletas tipo cookie, con utilización de harina de baya de uva, con un porcentaje del 92.6% de aceptación positiva por parte de los consumidores evaluados. En lo que se refiere a la intención de compra del nuevo producto, los evaluadores demostraron un porcentaje del 78% de intención de compra

The extinction model studied in this analysis is motivated by the search for signatures of strong gravity at the TeV scale (terascale gravity) and assumes the existence of string couplings in the strong-coupling limit. In this limit, the string model predicts the suppression of all high-transverse-momentum standard model processes, including jet production, beyond a certain energy scale. To test this prediction, the measured transverse-momentum spectrum is compared to the theoretical prediction of the standard model. No significant deficit of events is found at high transverse momentum. A 95% confidence level lower limit of 3.3 TeV is set on the extinction mass scale

Searches for electroweak neutralino and chargino production in channels with Higgs, Z, and W bosons in pp collisions at 8 TeV

Searches for supersymmetry (SUSY) are presented based on the electroweak pair production of neutralinos and charginos, leading to decay channels with Higgs, Z, and W bosons and undetected lightest SUSY particles (LSPs). The data sample corresponds to an integrated luminosity of about 19.5 fb(-1) of proton-proton collisions at a center-of-mass energy of 8 TeV collected in 2012 with the CMS detector at the LHC. The main emphasis is neutralino pair production in which each neutralino decays either to a Higgs boson (h) and an LSP or to a Z boson and an LSP, leading to hh, hZ, and ZZ states with missing transverse energy (E-T(miss)). A second aspect is chargino-neutralino pair production, leading to hW states with E-T(miss). The decays of a Higgs boson to a bottom-quark pair, to a photon pair, and to final states with leptons are considered in conjunction with hadronic and leptonic decay modes of the Z and W bosons. No evidence is found for supersymmetric particles, and 95% confidence level upper limits are evaluated for the respective pair production cross sections and for neutralino and chargino mass values
