Selection criteria for preoperative endoscopic retrograde cholangiopancreatography before laparoscopic cholecystectomy and endoscopic treatment of bile duct stones. Results of a retrospective; single center study between 1996-2002 [PDF]

, 2004
AIM: The optimal treatment for bile duct stones (in terms of cost, complications and accuracy) is unclear. The aim of our study was to determine the predictive factors for preoperative endoscopic retrograde cholangiopancreatography (ERCP).

A Note on the Distribution of Atmospherically Ducted Signal Power Near the Earth's Surface [PDF]

IEEE Transactions on Communications, 1982
Interference fields caused by low-level atmospheric ducts are of concern at UHF frequencies and above. This note develops a long-term median distribution of received signal power during ducting conditions from observations taken on a 175 km, 5 GHz path in New Jersey in 1966.

Retrieving evaporation duct heights from measured propagation factors

, 2007
International audienceThe knowledge of refractivity is very important for coverage prediction. This problem is common above sea, where the particular atmospheric conditions lead to atmospheric ducts which strongly modify the range of the radar compared ...

Assessment‐driven learning: Using a redesigned table test in anatomy lab—Pilot study

Anatomical Sciences Education, EarlyView.
Abstract The table test is a formative, group‐based assessment conducted during cadaveric dissection. The anatomy faculty at Carle Illinois College of Medicine modified its structure (redesigned table test) to include individual accountability (one question per student) and a collaborative clinical application question.

Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

Biological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Riding on a Pegasus: Is ‘Sustainability’ Still a Myth in Bangladesh's RMG Sector?

Business Strategy and the Environment, EarlyView.
ABSTRACT Although a growing number of studies explore sustainability, the role of stakeholders and institutions in shaping environmental sustainability initiatives remains overlooked particularly from the upstream fashion supply chain contexts. Drawing upon the framework proposed by Lee, our study aims to fill this gap by examining the interplay ...
