Acute aortic dissection on CT: is D-dimer determination useful for a timely and correct diagnosis? A case report.

Background: Chest pain is a common reason patients are admitted to the hospital. The most clinically significant cases are those in which the pain is due to an immediate life-threatening condition, such as acute aortic dissection (AAD). A prompt and correct diagnosis is crucial to patient survival.

Electroless deposition of Ni-P-nano-ZrO2 composite coatings in the presence of various types of surfactants.

Ni-P-nano-ZrO(2) coatings were produced using the electroless deposition technique. To prevent agglomeration of zirconia nanoparticles in the plating bath, various surfactant additives (anionic, cationic, and nonionic) were used. The most stable bath was obtained with the addition of dodecyltrimethylammonium bromide (DTAB).
