ISIS threatens to kill Pamela Geller: “Our aim was the khanzeer (pig) Pamela Geller…. we will send all our Lions to achieve her slaughter”
Excerpted from an article by Sasha Goldstein and Jason Silverstein, NY Daily News
ISIS appears to declare war on controversial blogger Pamela Geller on Tuesday in an ominous online message claiming it has fighters across America ready to attack “any target we desire.”
The threat, posted on anonymous message board JustPasteIt, singles out Geller, who helped plan a Prophet Muhammad cartoon contest that was attacked by two gunmen in Garland, Texas, over the weekend. ISIS claimed responsibility for the shooting early Tuesday, marking the first time the terror group called an American attack one of its own, though lawmakers believe the two men were influenced by the group, not guided directly by it.
“This is the textbook case of what we’re most concerned about,” Rep. Michael McCaul, the chairman of the House Homeland Security Committee, told the Associated Press.
Both the FBI and the Department of Homeland Security were aware the contest was a potential terror target and issued a joint bulletin on April 20. Organizers, including Geller – who has become a lightning rod for critics who think she promotes anti-Islam views – knew they’d be targeted but refused to back down.
The chilling Tuesday post also boasts of ISIS having “71 trained soldiers in 15 different states ready at our word to attack.” It specifically names Virginia, Maryland, Illinois, Michigan and California.
“This threat illustrates the savagery and barbarism of the Islamic State,” Geller told the Daily News in a statement she later posted on her website.“They want me dead for violating Sharia blasphemy laws. What remains to be seen is whether the free world will finaly wake up and stand for the freedom of speech, or instead kowtow to this evil and continue to denounce me.”
Asked if she would increase security or cancel any public appearances, Geller told the News, “Of course,” but said she could not elaborate for security reasons.
Equilibrado de piezas
El equilibrado representa una fase clave en las tareas de mantenimiento de maquinaria agricola, asi como en la fabricacion de ejes, volantes, rotores y armaduras de motores electricos. Un desequilibrio provoca vibraciones que aceleran el desgaste de los rodamientos, generan sobrecalentamiento e incluso pueden causar la rotura de los componentes. Para evitar fallos mecanicos, es fundamental identificar y corregir el desequilibrio de forma temprana utilizando metodos modernos de diagnostico.
Principales metodos de equilibrado
Hay diferentes tecnicas para corregir el desequilibrio, dependiendo del tipo de pieza y la intensidad de las vibraciones:
Equilibrado dinamico – Se utiliza en componentes rotativos (rotores, ejes) y se lleva a cabo mediante maquinas equilibradoras especializadas.
Equilibrado estatico – Se usa en volantes, ruedas y otras piezas donde basta con compensar el peso en un solo plano.
Correccion del desequilibrio – Se lleva a cabo mediante:
Perforado (eliminacion de material en la zona mas pesada),
Colocacion de contrapesos (en ruedas y aros de volantes),
Ajuste de masas de balanceo (como en el caso de los ciguenales).
Diagnostico del desequilibrio: equipos utilizados
Para identificar con precision las vibraciones y el desequilibrio, se utilizan:
Equipos equilibradores – Permiten medir el nivel de vibracion y definen con precision los puntos de correccion.
Equipos analizadores de vibraciones – Registran el espectro de oscilaciones, detectando no solo el desequilibrio, sino tambien otros defectos (por ejemplo, el desgaste de rodamientos).
Sistemas de medicion laser – Se emplean para mediciones de alta precision en mecanismos criticos.
Especial atencion merecen las velocidades criticas de rotacion – condiciones en las que la vibracion se incrementa de forma significativa debido a fenomenos de resonancia. Un equilibrado adecuado evita danos en el equipo bajo estas condiciones.
