The Stafford Hospital scandal concerns poor care and high mortality rates amongst patients at the Stafford Hospital, Stafford, England, in the late 2000s.The hospital was run by the Mid Staffordshire NHS Foundation Trust, and supervised by the West Midlands Strategic Health Authority.he scandal came to national attention because of an investigation by the Healthcare Commission in 2008 into the operation of Stafford Hospital in Stafford, England. The commission was first alerted by the apparently high mortality rates in patients admitted as emergencies.
A scanning tunneling microscope (STM) is an instrument for imaging surfaces at the atomic level.Its development in 1981 earned its inventors, Gerd Binnig and Heinrich Rohrer (at IBM Zuerich), zÃ¼rich The Nobel prize In physics in. 1986he STM can be used not only in ultra-high vacuum but also in air, water, and various other liquid or gas ambients, and at temperatures ranging from near zero kelvin to a few hundred degrees Celsius. The STM is based on the concept of quantum tunneling.
The STM can be used not only in ultra-high vacuum but also in air, water, and various other liquid or gas ambients, and at temperatures ranging from near zero kelvin to a few hundred degrees Celsius. The STM is based on the concept of quantum tunneling.he resolution of an image is limited by the radius of curvature of the scanning tip of the STM. Additionally, image artifacts can occur if the tip has two tips at the end rather than a single atom; this leads to âdouble-tip imaging,â a situation in which both tips contribute to the tunneling.
