Example of restored and balanced section from National Wildlife Refuge 1002 Area, Alaska. In structural geology section restoration or palinspastic restoration is a technique used to progressively undeform a geological section in an attempt to validate the interpretation used to build the section.
Boutonniere deformity is a deformed position of the fingers or toes, in which the joint nearest the knuckle (the proximal interphalangeal joint, or PIP) is permanently bent toward the palm while the farthest joint (the distal interphalangeal joint, or DIP) is bent back away (PIP flexion with DIP hyperextension).
Central slip is the tendon on the top of the finger attached to the middle bone of the finger, aiding the straightening of the middle PIP joint [1] The primary cause of boutonnière deformity is trauma, such as blunt force, lacerations, or dislocations.
This method was established by Bott [5] in 1959, based on the assumption that direction and sense of slip occurs on the fault plane are the same with those of the maximum resolved shear stress, hence, with known orientations and senses of movements on abundant faults, a particular solution T (the reduce stress tensor) is attained. [5]
Late Quaternary slip rates have been reported along the majority of the length of the Altyn Tagh fault and include measurements from geodetic techniques (e.g., GPS surveys and InSAR), traditional paleoseismic trenching, and on the basis of offset and dated landforms (morphochronology). The majority of these studies have focused on the central ...
Reconfiguring the piercing point back in its original position is the primary way geologists can find out the minimum slip, or displacement, along a fault. This can be done on a large scale (over many kilometers [ 2 ] ), a small scale (inside a single outcrop or fault trench [ 3 ] ) or even a single hand sample/rock (see image).
The first residential building of slipform construction; erected in 1950 in Västertorp, Sweden, by AB Bygging Later picture of the residential building in Västertorp. Slip forming, continuous poured, continuously formed, or slipform construction is a construction method in which concrete is placed into a form that may be in continuous motion horizontally, or incrementally raised vertically.
Celsus Library in Ephesus (), anastylosis carried out 1970–1978. Anastylosis (from the Ancient Greek: αναστήλωσις, -εως; ανα, ana = "again", and στηλόω = "to erect [a stela or building]") is an architectural conservation term for a reconstruction technique whereby a ruined building or monument is re-erected using the original architectural elements to the greatest ...
