The design of a 1 ns cycle-time microprocessor by a small team poses unique problems in computer-aided design. In this paper, we describe a complete set of tools which combines the obsession with performance of full custom design with the ease of use of semi-custom design. d i g i t a l Western Research Laboratory 250 University Avenue Palo Alto, California 94301 USA Table of

Green roofs can mitigate urban rooftop stormwater runoff. However, the lack of accurate, physically-based performance assessment and design models has hindered their wide application. Most hydrologic or hydraulic models have no direct connection to the physical properties of green roof components such as media type/depth, drainage depth, etc. In an effort to assist design engineers, a simplifie...

This report summarizes the results of 64 percutaneous catheter drainage of abdominal abscesses and fluid collections in 56 patients. Aspiration and drainage was guided with computed tomography in 34 patients and with ultrasound in 30 patients. Success rate was 90%. Infected collections were successfully drained in 94% and noninfected collections in 72% . Partial success was achieved in two...

BACKGROUND AND PURPOSE Aspiration of secretions containing bacterial pathogens into the lower respiratory tract is the main cause of ventilator-associated pneumonia. Endotracheal tubes with subglottic secretion drainage can potentially reduce this and, therefore, the incidence of ventilator-associated pneumonia. New evidence on subglottic secretion drainage as a preventive measure for ventilato...

OBJECTIVE To evaluate discordancy between clinical predictions and lymphatic drainage patterns of primary cutaneous melanoma as determined by preoperative lymphoscintigraphy and intraoperative lymphatic mapping of sentinel lymph nodes (SLNs). DESIGN Before selective SLN dissection, 226 consecutive patients with melanoma underwent preoperative lymphoscintigraphy. SETTING Teaching hospital te...

HYPOTHESIS Predictive factors of pancreatic fistula (PF) and the value of conservative management of PF following distal pancreatectomy (DP) are poorly known. DESIGN Case series. SETTING A university hospital referral center. PATIENTS From 1991 to 2003, 175 patients underwent DP with routine drainage of the pancreatic stump and postoperative repeated measures in drainage fluid. Pancreatic...
