2012年

作者： david lewis Yewdall

ISBN: (纸本)9780240812403

Practical Art of Motion Picture Sound, 4th edition relies on the professional experience of the author and other top sound craftspeople to provide a comprehensive explanation of film sound, including mixing, dubbing, workflow, budgeting, and digital audio techniques. Practically grounded with real-world stories from the trenches throughout, the book also provides relevant technical data, as well as an appreciation of all the processes involved in creating optimal motion picture sound. New to this edition are exclusive sound artist lessons from the field (including 2 new production cases studies), including insight from craftspeople who have worked on the latest Harry Potter and Batman films. All technological changes have been updated to reflect the most current systems. **Due to a manufacturing error, the Yewdall Sound FX Library is not available on the DVD included with the book. Please visit the book’s website, to download the full library.**

Is there a role for serum endothelin in predicting the severity of acute pancreatitis?

引用

Hepatobiliary & Pancreatic Diseases International 2006年第2期5卷 290-293页

作者： John Bennett david Cooper Anita Balakrishnan Michael Rhodes Michael lewis Department of Surgery Norfolk and Norwich University Hospital Colney LaneNorwichNorfolkNR4 7UYEngland

BACKGROUND: Acute pancreatitis remains a common presentation to acute surgical units and carries significant morbidity and mortality. The progression of the disease to necrotizing pancreatitis and multi-organ dysfunction syndrome (MODS) is associated with a very poor clinical outcome, and persistendy high mortality. Increases in serum endothelin (ET) have been seen in animal models of acute pancreatitis and this study aims to investigate whether there is a change in serum ET-1 in patients with acute pancreatitis and whether any such change is linked to disease severity. METHODS: All patients admitted with acute pancreatitis were prospectively recruited from die emergency admissions at the Norfolk and Norwich University Hospital. Serum ET levels were determined on admission, at 24 hours and 5 days post admission. Healthy adult controls were recruited from dermatology outpatients. RESULTS: A total of 21 patients joined the trial after giving informed consent. There were 3 men and 18 women with a median age of 65 years (range 26-87 years). Serum ET levels were significantly higher in acute pancreatitis patients than in normal controls (P <0. 05). An association was seen between persistendy raised serum ET levels and progression to MODS. CONCLUSIONS: The study does demonstrate a correlation between the circulating levels of ET and acute pancreatitis in humans, although it does not elicit its involvement in the pathogenesis of the disease. The observation that a persistendy high level of circulating ET-1 is associated with progression to MODS may indicate a role for ET in the monitoring of acute pancreatitis patients for recovery or progression to MODS.

Adaptation as a Water Resource Policy Challenge —Institutions and Science

引用

Journal of Water Resource and Protection 2013年第4期5卷 1-6页

作者： david lewis Feldman Department of Planning Policy and Design and Political Science University of California Irvine USA

Adaptation is the pursuit of active, deliberate measures to enhance humankind’s capacity to manage water supply and attenuate demand in the face of climate uncertainty. This article contends that worsening constraints upon freshwater due to climate variability demand concerted, imaginative, science-based solutions. These solutions must join creative management to co-production of climate knowledge. Through a series of case studies, we analyze the need for adaptation approaches to prevail over climate variability, and the role of these factors to facilitate their implementation. We also examine how translation of climate knowledge is helping spur adaptation at various spatial levels. These experiences point to the challenges in adaptation, and the adversity various regions will be faced if we do not.
