Catheterization and Cardiovascular Interventions, 2021
Key Points Transseptal access has been widely disseminated with a relatively low complication rate. The VersaCross Transseptal system utilizes radiofrequency energy to facilitate transseptal access enhancing ease and efficiency of procedures. Rising costs of structural heart interventions may impact resource allocation for medical devices.

Indirect calorimetric measurements were made on two athletes running at different speeds up to 22 km/hr at grades from -20 to +15%; the function was found to be linearly related to speed. Within these limits, the net kilocalories per kilogram per kilometer values seem to be independent of speed and related only to the incline. These values are about 5–

Energy cost and energy sources in karate
European Journal of Applied Physiology and Occupational Physiology, 1995Energy costs and energy sources in karate (wado style) were studied in eight male practitioners (age 23.8 years, mass 72.3 kg, maximal oxygen consumption (VO2max) 36.8 ml.min-1.kg-1) performing six katas (formal, organized movement sequences) of increasing duration (from approximately 10 s to approximately 80 s). Oxygen consumption (VO2) was determined

Renewable Energy's Hidden Costs
Scientific American, 2013The article discusses the hidden costs of renewable energy sources, such as solar and wind power, which includes graphs showing the amount of metals needed for renewable energy infrastructure, such as metal for growing rapeseed oil, nickel in wind power, and tin and silver in solar power.

What are the costs of energy? Energy costs across the world depend on a number of factors. Fossil fuels, which are commodities, are priced on the international market, but local conditions determine the costs of renewable energy.

This experiment was concerned with determining the energy cost of two popular Western square dancing routines: the “Mish-Mash,” which is a relatively fast-moving dance with quick movements, and the “Singing” dance, which is a slower and more deliberate type of dance. The subjects were four middle-aged couples, veteran members of a local square dancing
