La cobertura de los fenómenos físicos experimentados en el flujo compresible es algo difícil de entender. Sin embargo, aquí damos una explicación breve acerca de las hipótesis empleadas en el análisis de flujo compresible. Una base só- lida para un estudio más avanzado y enfocado, y la comprensión de las causas de flujo compresible para diferenciar de los flujos incompresibles y la forma en que se pueden analizar es vital para resolver problemas reales en aerodinámica. Los asuntos de comprensibilidad aparecen cuando los fluidos se están moviendo con una veloci- dad mayor que la velocidad del sonido la cual es equivalente al valor del número Mach 0.3. Es importante entender el comportamiento del fluido por encima de este valor de número Mach porque los factores de comprensibilidad afectan al fluido y se necesitaría tomar en cuenta tales factores para conseguir resultados ce...

El objetivo de este trabajo es analizar el término ‘inmersión’ en los videojuegos para poder realizar una categorización posterior de los principales factores que intervienen, de qué manera influyen sobre el jugador y por qué unos juegos divierten más que otros. El artículo muestra que la inmersión es un estado transitorio con pérdida de consciencia temporal y espacial, que se produce en diferentes fases según el nivel de implicación del jugador, y que genera una satisfacción y experiencia positiva, determinada por factores humanos y factores tecnológicos. Asimismo, requiere que exista coincidencia entre las expectativas del jugador y el juego, consistencia entre la vida real y las convenciones del mundo representado, y que se produzca un impacto no trivial en las acciones del jugador.

When a company produces goods or services must invest funds in working capital waiting for profit. To estimate whether this activity generates profits is necessary to develop the operating budget as a Profits Plan. As Finance Manager responsible for managing efficiently the funds generated by the operations of the company, musts prepare the Cash Flow from Profit Plan. Therefore it is objective of this article submit how prepare the Cash Flow from a Profits Plan.

Both systemic and uterine cardiovascular physiological changes in pregnancy are fundamental for blood flow increase in the uterus, microcirculation and circulation in the intervillous space. Pathophysiological changes in uterine and placental circulation are associated to preeclampsia and intrauterine growth restriction. In this review the anatomy of the uterine blood flow, uterine blood flow during pregnancy and clinical implications are described.

The objective of this paper is to determine the variables associated with the weight that Peruvian immigration has in the total immigration in Chile for the period 2005-2014. The initial hypothesis is that the Peruvian migratory flow has a social and economic component. The results showed that an increase in the Human Development Index (HDI) in favor of Chile increases the migratory flow. On the other hand, a larger education budget in favor of Chile decreases the migratory flow of Peruvian citizens.

Population growth, climate change and global warming are the great challenges facing agriculture in the 21st century. Therefore, it is necessary to increase the efficiency of selection of new varieties in plant breeding programs. In this regard, flow cytometry has proven to be a very powerful tool to speed-up selection processes in plant breeding because of its versatility and capacity to evaluate large populations.

The purpose of this paper is to explain why the member countries of the Andean Community (AC), have taken so long to complete the Andean Free Trade Area and have repeatedly delayed the deadline for achieving the Andean Customs Union. The go decision-making process arrives to two main findings. First that the top priority for the AC member countries has been to improve their individual chances to negotiate favorable agreements with their major trading partners, which are all outside the AC. Second, that both governments and businesses of the AC member countries rely too heavily on primary exports and tend so to underestimate the importance of the higher value-added content of the intra-AC trade.

In this work we are interested in studying the existence of stationary solutions for a Navier--Stokes--3D equation in a compressible and isothermal flow. In order to prove the existence of solutions we use a method of successive approximations, following the results shown by M. Padula.

Cuando una empresa produce para el mercado bienes o servicios debe invertir fondos en capital de trabajo a la espera de obtener ganancias. Para estimar si esta actividad le genera utilidades es necesario elaborar el presupuesto operativo como un plan de utilidades. Como el Gerente financiero es el responsable de administrar eficientemente los fondos generados por las operaciones de la empresa surge la inquietud de preparar el Cash Flow (Flujo de Caja) a partir del Plan de utilidades. Por lo tanto es objetivo del presente artículo detallar como preparar el Flujo de Caja o Cash Flow a partir del Plan de Utilidades.

Rheological and physicochemical analyses were conducted on nine varieties of peach pulps from Mendoza (Argentina) at a range of soluble solids concentration (12.5 to 28°Brix) and temperatures (30 to 50°C).The rheology of the pulps followed the power law model for all conditions, behaving as pseudoplastic fluids. Rheological: consistency coefficient and flow behavior index, using a rotational type viscometer and physicochemical parameters (methods proposed by AOAC): soluble solids, pH, water content, insoluble solids, acidity and pectin content (refractometric method) were determined in this study. Cluster analysis established two groups (1: Halford, Andross, Astengo, Bowen, Sim’s Cling; 2: Fortuna, Loadel and Palora; Sullivan Cling variety could not be assigned to any group) with significant differences.

Prediction of the river flow, irradiance and wind velocity is a challenge for all the countries to improve the natural resources, the uses of the satellite and meteorological data allow to improve the statistical processing, in this research article a new methodology is proposed for the river flow forecasting in Lima, it is associated to the Transandean tunnel with the watershed of the Atlantic and Pacific ocean. with the basins of Tamboraque, Sheque and Tulumayo. Our findings are the implementation of river flow prediction with the data from 2016 to 2022 with an hourly data, the forecasting allows to obtain information from the satellite data of ambient temperature, rainfall precipitation, wind velocity and atmospheric pressure and evaluated river flows in three basins, with the MAE and RMSE metrics evaluation, it is Tamboraque (3.63 m/s and 5.55), Sheque (0.92 m/s and 1.29 m/s) and Tul...

In the present work, the simulation model of groundwater flow in a stationary regime has been elaborated in the area of the Ticlio mining unit over 300 hectares of surface and 4814 meters of altitude. Geologically, the unit is made up of karst aquifers and fissured and clastic aquitards, which store and carry water. The main source of recharge of the aquifers are the precipitations that occur during the rainy periods and the melting of the glaciers, which are stored in the San Nicolás and Santa Catalina lagoons, constituting these as the recharge sources of the mentioned aquifers during the periods of low water. The analytically estimated hydraulic conductivity and hydraulic transmissivity are 0.068 m / d and 6.48 m2 / d respectively, values that must be corroborated by hydraulic tests to be carried out in wells or piezometers. The balance obtained with the aquifer simulatio...

The Unified power flow controller (UPFC) is the most important contribution of the power electronics in the modern Electrical Power Systems. The UPFC is able to decouple the control of the active and reactive power sent trough the transmission line. This control is performed byinjecting in series with the transmission line a voltage with regulated magnitude and phase, generated by a PWM voltage source inverter (VSI). When the current flow in the line originate in the inverter an active and reactive power. The active part of the power require to be eithersupplied or absorbed by a device, e.g. a second inverter. In this paper, simulation result obtained with a fundamental model of UPFC connected to a simple AC transmission system, and a control system base on "dq" transformation necessary to obtained the P and Q decoupled control ispresented.
