The privilege process: How doctors get privileges at hospitals. Patients, naturally, want good, qualified doctors. But so do hospitals. That means that simply being a licensed physician does not guarantee doctors will be granted hospital privileges, area hospital executives say.
Stirring is a more gentle technique for mixing cocktails and is used to delicately combine the drinks with a perfect amount of dilution from the ice. Many gin and whiskey cocktails are stirred because shaking is said to bruise the spirit (though that is also up for debate).
Both refluxing and distillation involve boiling of a solution. Stirring makes the solution boil more smoothly without becoming superheated. Without stirring, a liquid heated in a container can become superheated and release vapour suddenly, sometimes violently. This sudden bubble of gas can cause the solution and reagents to be thrown through the condensor, which is potentially dangerous, and can ruin the distillation.
