The aim of this study was to evaluate utilization of chemical energy in relation to myocardial mechanics in variably afterloaded contractions of cardiac muscle by determining total energy utilization (—P) in the absence of energy production. Right ventricular papillary muscles of cats were equilibrated at 26°C in a myograph in Krebs' solution while contracting isometrically (12/ min). Following...

Passive solar systems such as solar chimneys need solar radiation in order to work. Therefore, they cannot present stable natural ventilation when solar energy vanishes: to have a more robust and stable condition, solar energy should be stored during the day and released back during the night. Phase change materials can save additional thermal energy during the day and release it during the nig...

Two process models are used to convert carbon dioxide into methanol. These processes have been extended and improved using Aspen Plus simulator software. Both processes are found in the CO2 correction system. In this machine, the desired synthesis gas is produced in a flexible configuration. At the same time, the conversion of CO2 to hydrogen via a copper-based catalyst ha...

The original definition of energy-proportional computing, first introduced by Barroso and Hölzle, does not characterize the energy efficiency of recent reconfigurable computers, resulting in non-intuitive “super-proportional” behavior. This paper proposes a new definition of “ideal” energy-proportional computing and new metrics to help design and configure systems to operate close to this ideal...

Pigs require energy for maintenance and productive purposes, and an accurate amount of available energy in feeds should be provided according to their energy requirement. Available energy in feeds for pigs has been characterized as DE, ME, or NE by considering sequential energy losses during digestion and metabolism from GE in feeds. Among these energy values, the NE system has been recognized ...

• Objective: To assess the impact of a drug utilization review (DUR) alert letter program on metformin discontinuation rates in patients with a metformin claim and an absolute contraindication to metformin

synchronization of rumen available protein and energy is one of the conceptual methods to increase the efficiency of utilization of nutrients by the ruminants the concept of synchronization energy and protein was first by jhonson, implying that maximum microbial protein synthesis could be achieved by matching the rate of organic matter and protein degradation. synchronization of rumen available...

OBJECTIVE To investigate the impact of national implementation of age restriction on fluoroquinolone prescription in children and adolescents. METHODS Data collected from the database of Health Insurance Review and Assessment Service in South Korea, a national health insurance system to analyze fluoroquinolone prescribing practice in children and adolescents younger than 18 years, between 200...

BACKGROUND The importance of creating and sustaining a strong culture of patient safety has been recognized as a critical component of safe medication use. This study aims to assess changes in attitudes toward patient safety culture and frequency of quality-related event (QRE) reporting after guided implementation of a continuous quality improvement (CQI) program in a panel of community pharmac...
