Ixcanul llega este jueves a las salas ticas
Carolina Calvo Primera Plana | Lunes 2 de Mayo, 2016
El 5 de mayo es la fecha del ansiado estreno en Costa Rica del largometraje Guatemalteco Ixcanul, el cual viene precedido por un histórico número de reconocimientos internacionales.
A la fecha la cinta ha acumulado unos 40 premios internacionales, entre los cuales se destaca el Oso de Plata obtenido en la edición 2015 de la Berlinale, el día de su estreno.
Además de Berlín, la película cosechó premios en festivales de México, Colombia, Francia, República Dominicana, Cracovia, Eslovaquia, Italia, Armenia, Perú, Noruega, Canadá, Bélgica, Ecuador, Cuba, Guatemala, Austria, Siberia y los Estados Unidos.
Ixcanul trata sobre una joven maya de 17 años que vive en las faldas de un volcán en Guatemala. Ella decide tomar control sobre su destino aunque el precio a pagar sea muy alto.
“El estreno de Ixcanul en Costa Rica era imperante, tomando en cuenta la altísima calidad del filme y su relevancia a nivel mundial. Nos sentimos orgullosos de poder seguir trayendo al país el mejor cine internacional y más aún si este es realizado en nuestros propios países”, comentó Karina Avellán, de la distribuidora Pacífica Grey.
Costa Rica es el segundo país de la región que estrena el filme, después de Guatemala. Aquí se podrá ver en el Cine Magaly, Cinépolis Terramall, CCM Plaza Mayor, Novacinemas Alajuela (Plaza Real Alajuela), y dos salas más que aún están por confirmar.
María Mercedes Coroy, protagonista de la película, es la mujer maya más joven en recibir 3 premios por su interpretación, y será la invitada especial el día del estreno en nuestro país.
El viernes 6 de mayo, María Mercedes Coroy tendrá un conversatorio con estudiantes en el auditorio del Instituto de Investigación en Educación (INIE) de la Universidad de Costa Rica. La actividad está programada a las a las 3 p.m. y es abierta al público.
Finalmente, el viernes 8 de mayo, en las salas de Cinépolis Terramall, la actriz asistirá a la función de las 8 p.m.; una vez concluida la proyección conversará con los asistentes.

Understanding Engine Vibration: Causes, Effects, and Solutions
Engine vibration is a critical concept that pertains to the operational efficiency and longevity of machinery. It refers to the oscillations resulting from various forces acting on an engine or rotor system. These vibrations can stem from unbalanced rotor mass distribution, mechanical failures, and operational conditions.
The Fundamentals of Engine Vibration
In an ideally balanced engine, the rotor's mass is symmetrically distributed about its axis. This balance ensures that the centrifugal forces exerted by different mass elements cancel each other out. When the symmetry of the rotor is disrupted, centrifugal forces can create an unbalanced condition, leading to vibrations. These vibrations not only affect the engine's performance but can also result in premature wear and failure of components if not addressed.
Types of Engine Vibration
Engine vibrations can be classified into static and dynamic types. Static vibrations occur when the rotor is at rest and exhibits heavy points due to gravitational forces. Conversely, dynamic vibrations are present only when the rotor is in motion, typically resulting from imbalanced mass distributions along the rotor's length. This distinction is essential for assessing vibration issues and determining appropriate corrective actions.
Dynamic Unbalance and Its Implications
Dynamic unbalance arises when equal and opposite forces act on different planes along the rotor's length. Unlike static unbalance, which may be corrected by adjusting weights while the engine is stationary, dynamic unbalance requires modifications during operation. Addressing dynamic unbalance is crucial as it can lead to significant wear on bearing surfaces, increased operational noise, and vibration, all of which compromise engine health and efficiency.
Causes of Engine Vibration
Several factors contribute to engine vibration, including:
Measuring Engine Vibration
Accurate measurement of engine vibration plays a vital role in diagnosing and addressing imbalance issues. Various sensors can be utilized, including:
Impact of Vibration on Engine Performance
Uncontrolled engine vibration can lead to several adverse effects:
Mitigating Engine Vibration
Several methods can be employed to mitigate engine vibration:
The Importance of Regular Monitoring
Regular monitoring of engine vibration is crucial. Advanced monitoring techniques, combined with modern vibration analysis tools, enable engineers to identify potential problems before they escalate. By measuring vibration levels and identifying patterns, engineers can make informed decisions on maintenance and repairs, ensuring optimal engine performance and extending its lifespan.
Conclusion
Understanding and managing engine vibration is vital for maintaining the operational integrity of machinery. By recognizing the common causes and implementing effective measurement and mitigation strategies, businesses can enhance the longevity and efficiency of their engines. Continuous monitoring, coupled with routine maintenance, will help mitigate the impacts of vibration and promote a healthier operating environment.
In modern engineering practices, recognizing the importance of balance and vibration analysis is paramount, and utilizing appropriate tools and techniques can lead to significant improvements in machine performance and reliability.
