When it comes to structural biology, bigger really is better. Most biological processes are performed by enormous multicomponent complexes, such as the ribosome. To solve the structures of these monsters, biologists traditionally have used two different but complementary techniques, nuclear magnetic resonance (NMR) and X-ray crystallography. They have had considerable success using the latter t...

Thrusting implication in the crustal thickening history of eastern Tibet is highly debated. The ?250 km-long Muli thrust Yalong belt SE a major Miocene structure with pronounced topographic step (?2,000 m). Using thermo-kinematic modeling based on thermochronology data, we constrain geometry as being steep (>70°) at surface, agreement field observations, and flattening depth (?20 km) an intra-c...

Creeping faults are difficult to assess for seismic hazard because they may participate in rupture even though likely cannot nucleate large earthquakes. The creeping central section of the San Andreas fault California (USA) has not participated a historical earthquake; however, earthquake ruptures nucleating locked northern and southern sections propagate through section. We used biomarker ther...

The cavernicolous species Prionoglaris kapralovi sp. nov. is described from Armenia. A key to the three of known adults given and variability some characters discussed. All published locality records genus, including those nymphs, are summarized, along with previously unpublished based on collection Geneva Natural History Museum.

Appearance of nationalism in each country is influenced by some social , religious and political factors throughout the history of that country In Iranian contemporary history, this process has also been dependent upon opinions and thoughts of some of the nationalist intellectuals and modernists their intellectual products played an important role in various social , intellectual and even artis...

In the present paper, time dependent creep behavior of hollow circular rotating cylinders made of exponentially graded material (EGM) is investigated. Loading is composed of an internal pressure, a distributed temperature field due to steady state heat conduction with convective boundary condition and a centrifugal body force. All the material properties are assumed to be exponentially graded a...
