On The Harmonic Oscillator Group

We discuss the maximum kinematical invariance group of the quantum harmonic oscillator from a view point of the Ermakov-type system. A six parameter family of the square integrable oscillator wave functions, which seems cannot be obtained by the standard separation of variables, is presented as an example. The invariance group of generalized driven harmonic oscillator is shown to be isomorphic to the corresponding Schroedinger group of the free particle.Comment: 11 pages, no figure

Gravitational cooling of self-gravitating Bose-Condensates

Equilibrium configurations for a self-gravitating scalar field with self-interaction are constructed. The corresponding Schr\"odinger-Poisson (SP) system is solved using finite differences assuming spherical symmetry. It is shown that equilibrium configurations of the SP system are late-time attractor solutions for initially quite arbitrary density profiles, which relax and virialize through the emission of scalar field bursts; a process dubbed gravitational cooling. Among other potential applications, these results indicate that scalar field dark matter models (in its different flavors) tolerate the introduction of a self-interaction term in the SP equations. This study can be useful in exploring models in which dark matter in galaxies is not point-like.Comment: 10 aastex pages, 12 eps figures. Accepted for publication in Ap

Efecto de la NIC 19 en el tratamiento contable de los beneficios sociales a corto plazo en la situación económica y financiera de la empresa Secucorp SAC en la Ciudad de Trujillo en el año 2015

En la presente investigación se tuvo por objetivo determinar de qué manera incide la Norma Internacional de Contabilidad Nº 19, en el tratamiento contable de los BENEFICIOS SOCIALES A CORTO PLAZO de los empleados, y su incidencia en la presentación razonable de la situación económica y financiera de la empresa SECUCORP S.A.C., de la ciudad de Trujillo. Hoy en día, algunas empresas todavía no aplican la normatividad correspondiente a las NORMAS INTERNACIONALES DE CONTABILIDAD (NIC), a pesar que, éstas se han adoptado para su aplicación obligatoria y general en la preparación razonable de los estados financieros de las empresas. La muestra estuvo constituida por los trabajadores de la empresa SECUCORP S.A.C., para poder verificar la hipótesis se aplicó el diseño lineal, pre experimental, ex post facto de un solo grupo, con observación antes y después de la aplicación de la NIC 19, con las técnicas de encuesta, observación y entrevista. Entre los principales resultados obtenidos que se pudo observar, es que la empresa reconoce los beneficios a los empleados, conforme a la normativa laboral, tributaria vigente en el Perú y no de acuerdo de la NIC 19, Beneficios sociales a corto plazo, afectando y distorsionando la información proporcionada en los estados financieros para la toma de decisiones por parte de la gerencia. Por lo tanto, lo que se pretende dar a conocer con la presente investigación, es que al no dar cumplimiento de los principios y normas contables, los resultados obtenidos durante el ejercicio económico no serían los correctos, por ende, afectaría la credibilidad de la unidad económica; y por consiguiente, una variación en su situación económica y financieraIn the present investigation aimed to determine how affects the implementation of the International Accounting Standard No. 19, for proper accounting treatment of SOCIAL BENEFITS SHORT TERM employee contributes to the fair presentation of the economic and financial situation company SECUCORP SAC, of the city of Trujillo. Today, some companies still do not apply the appropriate regulations to International Accounting Standards (IAS), although, they have adopted for mandatory application in the reasonable preparation of financial statements of companies. Currently the company SECUCORP SAC; does not perform an adequate accounting treatment of SOCIAL BENEFITS SHORT TERM employees, this entails that the company may have legal problems by failing to comply and not recognize the benefit to future generated by the worker to provide services, as it you can generate fines and this can damage their profitability; besides not having budgeted for those expenses from the time that accrues no social security contributions. The sample was made by the company SECUCORP SAC to obtain data domains of the variables, linear design was applied, pre experimental, ex post facto of a single group, with observation before and after application of IAS 19 with survey techniques, observation and interview. Among the main results could be observed, it is that the company recognizes the benefits to employees under labor, legal and tax regulations in force in Peru and not according to IAS 19, benefits in the short term, affecting and distorting the information provided in the financial statements for decisionmaking by management. There fore, what is intended to describe in this research is that by failing to comply with the accounting principles and standards, the results obtained during the fiscal year would not be correct, therefore, it affects the credibility of the unit economic; and therefore a change in its economic and financial situatio

A ringed pole-on outflow from DO Tauri revealed by ALMA

We present new ALMA Band 6 observations including the CO (2-1) line and 1.3 mmcontinuum emission from the surroundings of the young stellar object DO Tauri. TheALMA CO molecular data show three different series of rings at different radial ve-locities. These rings have radii around 220 au and 800 au. We make individual fits tothe rings and note that their centers are aligned with DO Tauri and its optical high-velocity jet. In addition, we notice that the velocity of these structures increases withthe separation from the young star. We discuss the data under the hypothesis that therings represent velocity cuts through three outflowing shells that are possibly drivenby a wide-angle wind, dragging the environment material along a direction close to theline of sight (i= 19◦). We estimate the dynamical ages, the mass, the momentum andthe energy of each individual outflow shell and those of the whole outflow. The resultsare in agreement with those found in outflows from Class II sources. We make a roughestimate for the size of the jet/wind launching region, which needs to be of.15 au.We report the physical characteristics of DO Tauri?s disk continuum emission (almostface-on and with a projected major axis in the north-south direction) and its velocitygradient orientation (north-south), indicative of disk rotation for a 1-2 Mcentral star.Finally we show an HST [SII] image of the optical jet and report a measurement of itsorientation in the plane of the sky.Fil: Fernandez Lopez, Manuel.

Wine routes in Spain: A case study

Spain is a country with an enormous wine-growing tradition and with a huge tourist industry, although it has not made the importance of wine tourism profitable. Thus, it was not until 2000 that different official wine routes seemed to appear, with the main objective, amongst others, being to help develop rural areas where wine production is of crucial importance and to offer alternatives to traditional sun and beach tourism. In this paper, we will present an analysis of wine tourism in Spain based on the premise that wine (and regional cuisine) may be, and very frequently is, the main reason for visiting a certain area. To investigate this, we will present the results of an empirical study carried out in one of the official wine routes of Andalusia, a Spanish region where sun and beach tourism and cultural tourism represent a highly significant part of tourist activity. We have analysed how this tourist route is bringing about significant socioeconomic changes to the geographical area. To achieve this aim, we have conducted a survey of the companies involved in the wine route in order to ascertain their opinions on the impact and influence of the route. The main results of the study demonstrate the need to consolidate the development of such routes through collaboration between public institutions, ensuring the participation of all the different social actors involved
