The recent development of WC-Co cemented carbide with plate-like WC grains;

Progress in the symmetrical triphenylene discotic liquid crystals;

Recent development of discotic liquid crystalline materials and their carrier transport properties;

Synthesis of unsymmetric triphenylene discotic liquid crystals with semi-fluorinated chain and the influence of fluorophobic effect on mesogenic behaviors

Objective To summarize the key points of caring the patients with rupture of vessel previa in velamentous placenta.

Midterm follow-up of symptomatic discoid meniscus after arthroscopic surgery;

On the condition of αmax≤[α], aimed at the minimal prime circle radius, the optimal solution of basic size of disk cam with translation follower was calculated and so the cam system with compact structure and gently weight was obtained.
