The Internal Family Systems Model (IFS) is an integrative approach to individual psychotherapy developed by Richard C. Schwartz in the 1980s. [ 1 ] [ 2 ] It combines systems thinking with the view that the mind is made up of relatively discrete subpersonalities , each with its own unique viewpoint and qualities.
Richard C. Schwartz (born 14 September 1949), [1] is an American systemic family therapist, academic, author, and creator of the Internal Family Systems (IFS) branch of therapy. [ 2 ] [ 3 ] He developed his foundational work with IFS in the 1980s [ 4 ] after noticing that his clients were made up of many different pieces of "parts" of their "Self."
The introduction of the 4-6-2 design in 1901 has been described as "a veritable milestone in locomotive progress". [3] On many railways worldwide, Pacific steam locomotives provided the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric or diesel-electric ...

[2] [3] In 1966 NASA released its FMECA procedure for use on the Apollo program. [4] FMECA was subsequently used on other NASA programs including Viking , Voyager , Magellan , and Galileo . [ 5 ] Possibly because MIL–P–1629 was replaced by MIL–STD–1629 (SHIPS) in 1974, development of FMECA is sometimes incorrectly attributed to NASA. [ 6 ]
Swiss classification: 4/6+4/5. The equivalent UIC classification is refined to (2'D)D1' for simple articulated locomotives. A locomotive of that length must be an articulated locomotive; meaning all have a joint between the first and second groups of driving wheels. All examples of this type are cab forwards. Normally, the leading truck sits ...
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, 6-8-6 represents the arrangement of six unpowered leading wheels, eight powered and coupled driving wheels, and six unpowered trailing wheels.
They were originally built as 2-6-6-2s but were refitted with a four-wheel leading truck to increase stability at speed. Southern Pacific AM-2s were built from July to August 1911 by Baldwin Locomotive Works as Cab Forwards. These 4-6-6-2s began retirement in the mid- to late-1930s, although a few remained in operation until the end of World ...
