We developed and validated a mitral valve orifice method for Doppler cardiac output determination. In 15 open-chest dogs, cardiac output was controlled and measured by a roller pump interposed between the right atrium and pulmonary artery as a right-heart bypass. Left heart flows were measured in the open-chest dog model by Doppler measurements at the mitral valve orifice and compared not only ...

Dancing on roller skates at discothecques has become very popular among the youth in the last number of years. During 1980 a number of these roller discotheques were opened in Belfast and it soon became apparent that significant numbers of young people were attending the Accident and Emergency Departments of hospitals in the city with injuries received while participating in this leisure activity.

AIM This study aims to determine the effect of the stationary rawx, roller, and the suspension cell culture systems on the total virus yield infectivity and antigenicity. MATERIALS AND METHODS Three serotypes of foot and mouth disease virus (FMDV) (serotype A, O and SAT-2) were inoculated separately into baby hamster kidney-21 cell line in rawx, roller, and suspension cultivation systems usin...

BACKGROUND Screening new lignocellulosic biomass pretreatments and advanced enzyme systems at process relevant conditions is a key factor in the development of economically viable lignocellulosic ethanol. Shake flasks, the reaction vessel commonly used for screening enzymatic saccharifications of cellulosic biomass, do not provide adequate mixing at high-solids concentrations when shaking is no...

Abstract The objective of the research is to analyze impact ultrasonic vibration assistance on wear resistance due topography enhancement caused Ti6Al4V cylindrical samples after surface modification through a ball burnishing process. process parameters considered for this study are force, number passes, and addition 40 kHz assistance, which thought enhance increase hardener effect in terms dep...

conceptualization The observations and reflections were distilled into 'abstract concepts' that produced plans for action which could be 'actively experimented' with during the second night Knowledge Management and IT 605 of study. Plans at the operational, project, organizational and research levels were distinguished: Operational level (asphalt team)  The asphalt temperature throughout the w...

1 I n t r o d u c t i o n In food industry, we can find many manipulative operations that deal with deformable rheologic materials such as dough, paste, jelly, and meat. Most these operations are done by humans. Especially, operations with large deformation of rheologic objects depend upon humans. For example, forming of pizza dough to a thin circular shape is performed by humans while extensio...

This paper describes the ROLLENT system submitted to the Eight International Planning Competition, Learning Track. ROLLENT combines two machine learning techniques: generation of entanglements and decision tree learning by ROLLER. Entanglements capture causal relationships for a class of problems while ROLLER learns relational decision trees useful to sort the applicable operators at a given st...

Mechanistic pavement design procedures based on elastic layer theory require characterization of all pavement layer materials including subgrade soil. This paper discusses the subgrade stiffness obtained from a new compaction device called the Intelligent Compaction (IC) roller on highway embankment projects in Kansas. Three test sections on two routes were compacted using a single, smooth stee...
