Desarrollo de un plan de negocios para un Car Wash movil en Santiago de Chile
(Universidad de Chile, 2017)
Según el Instituto Nacional de Estadísticas, a nivel nacional el parque vehicular ha crecido sobre el 7% anual durante los últimos 5 años, llegando a más de 4,5 millones de vehículos el 2014, de los que casi un 30% corresponden a la categoría de...
CDVCH Centro de difusión del vino chileno

(Universidad de Chile, 2012)
Una red tipo darknet es una porción de direcciones IPs asignado y ruteado en el cual no existen servicios activos ni servidores. Actualmente no existe un sistema, públicamente disponible, que permita la visualizar de forma gráfica los datos...
El futuro de la hipoteca inversa en Chile
(Universidad de Chile, 2014)
En este trabajo se presenta la hipoteca inversa tal como se le ha concebido en el derecho foráneo, con sus fundamentos y objetivos, para luego realizar un análisis de juridicidad desde el ordenamiento vigente contrastándola con las normas chilenas...
Caracterización del quehacer fonoaudiológico en dos contextos de atención: centros comunitarios de rehabilitación y hospitales de salud pública
(Universidad de Chile, 2014)
La disciplina fonoaudiológica se inició en la Universidad de Chile en la década del 70‘. El (la) fonoaudiólogo (a) puede desempeñarse en diversos contextos con distintas estrategias de atención como la hospitalaria del modelo biomédico y...
Phonoaudiologic discipline began at the University of Chile in the 70s'. The phonoaudiologic may perform in different contexts with different strategies as hospital care of the biomedical model and Community Based Rehabilitation (CBR) of the biopsychosocial model in the Community Centers Rehabilitation (CCR). The assessment of the social contexts in which this professional is inserted, had modified care strategies employed and generally Phonoaudiologic practice, based on this the following research questions are formulated 1) How to conceive and carry out their professional work phonoaudiologists inserts CCRs? 2) How to conceive and carry out their professional work phonoaudiologist inserts in public hospitals?. The objective of this research was to characterize the professional experiences of speech therapists (as) that perform both RACs and public hospitals. Specific objectives were to describe meaning and implementation of the work of the phonoaudiologists inserts in both care settings. This research‘s nature is qualitative and the techniques used to obtain information in-depth interviews were analyzed with the Atlas Ti program and nonparticipants observations of professional work of two speech fonoaudiologists who employed the strategy of RBC and 2 hospital strategy, all more than one year at the institution. It was concluded that phonoaudiological work is constructed based on the knowledge acquired in undergraduate and influenced by the work context in which professional works....

Desarrollo de métodos simuladores para determinar la fracción biodisponible de triclocarbán en suelos tratados con biosólidos
(Universidad de Chile, 2016)
Los biosólidos son residuos del tratamiento de aguas servidas, que al ser tratados y procesados, pueden ser reciclados y aplicados como co-fertilizantes en suelos. También pueden ser una fuente de contaminación de diversos tipos de compuestos...
Biosolids are a residue of water treatment, which when are treated and/or processed, can be recycled and used as co-fertilizing agents in soils. They are also a pollution focus of organic compounds. Triclocarban (TCC) has been widely used since 1970, as antimicrobial agent in soaps, mouthwashes and toothpastes. This compound, is non-polar, reason why it binds with organic matter of the biosolids. The determination of the bioavailable fraction involves the use of plants or animals and prolonged study time. Therefore, it is necessary to develop simulating methodologies for a rapid and simple determination of the bioavailability of TCC in soils amended with biosolids. Two extraction methods may be suitable: the use of an aqueous solution of hydroxypropyl-β-cyclodextrin (HP-β-CD) and the aqueous extraction with CaCl2 followed by an extraction with the rotating disk in two orientations, horizontal and vertical (EA/RDSE), using as vegetal tissue wheat plants. In crops of wheat plants in soil-biosolid systems, TCC was detected in the roots. On the other hand, in plants grew with spiked biosolids and biosolids with high “native” concentration of TCC, it was detected in roots and shoots. Translocation factor are lower than 1, showing that TCC remains preferentially in the root. Bioconcentration factors (BCF) is the ratio of the concentration of TCC in plant tissue and soil. For the roots and shoots, is obtained that soils treated with biosolids do not accumulate TCC, cause FBC <1, with exception of the soil treated with biosolids with a high concentration of “native” TCC (FBC: 1,7). Concentration factor (CF) were calculated for the simulator methods. For the extraction with HP-β-CD, FC<1 indicating that this methodology does not overestimate the bioavailable fraction, but behaves very similar to it. For the EA/RDSE method, FC of 10-4 are obtained, corroborating TCC characteristic such as low solubility. To validate the methods as biosimulators, a modeling through a simple correlation between TCC concentration in plant tissue and concentrations determined by simulator methods is used (HP-β-CD and EA/RDSE, 95% significant). For the cyclodextrin, significant correlations are obtained and explain between 37 and 95% of the variability for roots and shoots. For the vertical mode of EA/RDSE, correlations are also significant explaining between the 26 and 57% of the variability for roots and shoots, respectively. For the horizontal mode, correlation is significant to the roots, with a model explanation of 81%. It can be concluded that, the two developed methodologies (HP-β-CD and EA/RDSE) are biosimulators of the TCC bioavailable fraction in the roots of wheat plants cultured in soils treated with biosolids...
