The Establishment of Charter Schools: A Guide to Legal Issues for Legislatures

El ritmo de vida de las personas en la actualidad se ha acelerado a tal punto que no cuentan con el tiempo necesario para realizar actividades esenciales. Destacando principalmente la función de cocinar, la cual resulta extenuante debido al engorroso proceso que implica llevarla a cabo. El proceso comprende el traslado al lugar de compra, la búsqueda de los insumos, la selección de los insumos, las largas colas para pagar, el lavado de los insumos así como el picado de los mismos, entre otras. Por ende, se propone una solución alternativa a este problema, la cual consiste en el delivery a través de la venta online de boxes con insumos frescos sin cocinar picados y en las cantidades exactas de diversos platillos criollos.The rhythm of life of the persons at present has hastened to such a point that they do not count with the necessary time to realize essential activities. Emphasizing principally the function to cook, which turns out to be exhausting due to the bothersome process that implies carrying out it. The process comprises the transfer to the place of buy, the search of the inputs, the selection of the inputs, the long tails to pay, the wash of the inputs as well as stung of the same ones, between others. Therefore, an alternative solution to this problem is proposed, which consists of the delivery through the online sale of boxes with fresh uncooked inputs chopped and the exact quantities of various Creole dishes. This paper seeks to determine the financial viability of the project in question in order to validate the possibility of implementing it in a real-world scenario.Trabajo de investigació

Scintillation light detection in the 6-m drift-length ProtoDUNE Dual Phase liquid argon TPC

DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6  ×  6  ×  6 m 3 liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019-2020 as a prototype of the DUNE Far Detector. Charged particles propagating through the LArTPC produce ionization and scintillation light. The scintillation light signal in these detectors can provide the trigger for non-beam events. In addition, it adds precise timing capabilities and improves the calorimetry measurements. In ProtoDUNE-DP, scintillation and electroluminescence light produced by cosmic muons in the LArTPC is collected by photomultiplier tubes placed up to 7 m away from the ionizing track. In this paper, the ProtoDUNE-DP photon detection system performance is evaluated with a particular focus on the different wavelength shifters, such as PEN and TPB, and the use of Xe-doped LAr, considering its future use in giant LArTPCs. The scintillation light production and propagation processes are analyzed and a comparison of simulation to data is performed, improving understanding of the liquid argon properties
