Arterial pulse pressure variation predicting fluid responsiveness in critically ill patients (Retracted article. See vol. 31, pg. 542, 2009)

In critically ill patients, it is important to predict which patients will have their systemic blood flow increased in response to volume expansion to avoid undesired hypovolemia and fluid overloading. Static parameters such as the central venous pressure, the pulmonary arterial occlusion pressure, and the left ventricular end-diastolic dimension cannot accurately discriminate between responders and nonresponders to a fluid challenge. In this regard, respiratory-induced changes in arterial pulse pressure have been demonstrated to accurately predict preload responsiveness in mechanically ventilated patients. Some experimental and clinical studies confirm the usefulness of arterial pulse pressure as a useful tool to guide fluid therapy in critically ill patients.

Evaluation of Asphalt Stabilizing Additives, HR-542, 1994

Efforts are constantly being put forth by researchers, highway related industries and product suppliers to improve the life and performance of asphalt pavements. As a result of those efforts, a variety of asphalt modifiers have been developed and evaluated in experimental sections over the years. Evaluations of the polymer asphalt modifiers have been done and results were usually compared with conventional sections within each respective project. The research presented in this report is also a comparison of asphalt modifiers with each other as well as a comparison of a modifier with its respective conventional section, when they exist. Several of the modifiers showed some improvements in performance while others did not.
