Dementia Is a Terminal Illness, But Palliative Care Often Poor. October 16, 2009 â A new study looking at the natural history of dementia into its end stages finds high rates of complications, high 6-month mortality rates, and a high number of distressing symptoms and aggressive interventions of questionable benefit.
Measuring Earthquakes. The vibrations produced by earthquakes are detected, recorded, and measured by instruments call seismographs. The zig-zag line made by a seismograph, called a seismogram, reflects the changing intensity of the vibrations by responding to the motion of the ground surface beneath the instrument.
Seismometers-instruments that measure motions of  the ground.   The visual output, either on a monitor or on paper is called a  seismograph   Seismometers are in part used to measure the intensity of  earthquakes. The scale used to measure earthquake intensity is  known as the Modified Mercalli scale.
