Part of the Software applications glossary: MDI (Multiple Document Interface) is a Microsoft Windows programming interface for creating an application that enables users to work with multiple documents at the same time. Each document is in a separate space with its own controls for scrolling.he user can see and work with different documents such as a spreadsheet, a text document, or a drawing space by simply moving the cursor from one space to another. An MDI application is something like the Windows desktop interface since both include multiple viewing spaces.
Tai Chi and Calories. To lose 1 pound of fat, you must burn 3,500 calories. A 30-minute tai chi session will burn roughly 150 calories for a 155-pound person -- about the same as walking at a moderate pace. Although you don't burn as many calories with tai chi as with more vigorous activities such as jogging, the numbers add up over time, potentially leading to weight loss over the weeks.
Avoid the weight. Bad news: The average person gains one to two pounds a year. Good news: Consuming just 100 fewer calories each day is enough to avert that weight gain. If you're finding this out a little too lateâand you want to actually lose some of that weightâyou have to downsize by 500 calories a day. But you don't have to slash them all from your plate. You can eat 250 calories less and then burn 250 by walking for 30 to 45 minutes. Over a week, that will produce about a pound of weight loss, says Holly Wyatt, MD, a clinical researcher at the Center for Human Nutrition in Denver.
