Leakage and rotordynamic performance of T type labyrinth seal
Aerospace Science and Technology, 2019A new type of seal, called a T type labyrinth seal is proposed to reduce exciting force induced by seal region flow, thereby reducing rotor vibration in aero-engines.

Experimental Study on the Pressure Distribution Mechanism Among Stages of the Magnetic Fluid Seal
IEEE transactions on magnetics, 2018One of the main engineering applications of ferrofluids is in magnetic fluid seals, working in rotary motion. An area, which has so far been insufficiently examined, is the mechanism of leaks between seal stages in this type of seal. This is an important

A Comparative Study of Ferrofluid Seal and Magnetorheological Fluid Seal
IEEE transactions on magnetics, 2018Compared with a ferrofluid (FF) seal used as a sealing material, magnetorheological (MR) fluid has higher sealing pressure at the same condition. This is because MR fluid not only has magnetic property but also shows obviously elasto-plastic performance,

Many stretchable electronic devices require stretchable hermetic seals. However, stretchability and permeability are inextricably linked at the molecular level: stretchable, low-permeability materials do not exist. We collect data for the permeation of water and oxygen in many materials and describe the scaling relations for both flat and wrinkled ...

Two young women developed septic arthritis in an interphalangeal joint following a seal bite. One patient was cured with tetracycline: the other required joint arthrodesis. This entity known as "seal finger" is common among sealers. Although the infection may be cured with tetracycline, in late treated or untreated cases joint destruction may occur. No

Seals, Sealings and Seal Impressions from Akrotiri in Thera
2019The monograph contains the primary publication of the seals (S1–S16), sealings (N1–N75) and stamped objects (I1–I3) retrieved at the Bronze Age site of Akrotiri in Thera. Their contexts date from the MC A period, which corresponds roughly to the Cretan MM I period (at the turn of the third to the second millennium BC), until the final volcanic ...

Quantitative Fault Seal Prediction
, 1997Fault seal can arise from reservoir/nonreservoir juxtaposition or by development of fault rock having high entry pressure. The methodology for evaluating these possibilities uses detailed seismic mapping and well analysis.

Abstract More than any other ancient work of art, seals are intimate objects which are literally bound to their owners. In ancient societies, their primary purpose was to secure property—whether in the home or the public arena—and to assign responsibility by means of clay sealings impressed by a specific individual who is identified by ...

The tissue adhesive property of fibrinogen was first described 60 years ago. However, it was not until the availability of concentrated plasma fibrinogen and bovine thrombin that the use of fibrin sealants in surgical practice became widespread.
