We present a concurrent higher-order programming language called Plain and a concomitant static type system. Plain is based on logic variables and computes with possibly partial data structures. The data structures of Plain are procedures, cells, and records. Plain’s type system features record-based subtyping, bounded existential polymorphism, and access modalities distinguishing between readi...

On occasion gastric ulcers may be recognized on plain abdominal radiographs. A case in which a gastric ulcer was diagnosed on the plain abdominal radiograph, illustrating the importance of careful scrutiny of the plain film in all cases of acute abdomen, is presented. The existence of the lesser curvature ulcer was confirmed on barium contrast studies.

OBJECTIVES This study examined the perceptions of cigarette packaging and the potential impact of plain packaging regulations.

Background: In cirrhotic patients undergoing ano-rectal surgery, spinal anesthesia/analgesia remains a challenge. Coagulopathy and intraoperative hypotension represent a major challenge for the anesthetist during spinal anesthesia in those patients. This study was designed to examine the efficacy and the adverse effects of ropivacaine (plain, hyperbaric) spinal anesthesia for anorectal surgery ...
