Summarize the following:
Any liquid dish soap will work for cleaning your shoes. Use about 1 teaspoon (4.9ml) of soap so the water is sudsy but still clear. Stir the cleaning solution with a toothbrush so it's evenly mixed. Soap and water work best on all kinds of shoes, including white leather. If you don't want to use dish soap, you can substitute 12 cup (120ml) of white vinegar. Dip the magic eraser into your soapy water and wring it out. Wipe in short back and forth motions along parts of your shoes made of leather, rubber, or plastic. Keep working the eraser until all scuffs and stains are removed. Magic erasers can be found in the cleaning section of your local department store. Dip the head of the toothbrush into the water so the bristles are wet. Work the bristles in small circular motions on the surface of your shoes, focusing on heavily stained areas. Use a slight amount of pressure to work the cleaning solution into the shoe's fabric. Keep the toothbrush you use to clean out of the bathroom to avoid any confusion. Use either a cloth or paper towel to pat the soapy water and dirt off of the shoe. Avoid wiping the towel across the shoe's fabric since you could spread the dirt across the fabric again. Don't try to completely dry your shoes with the towel. Just lift off the excess cleaning solution from the surface. After you initially pat them with a towel, put them in a well-ventilated area in your home so they can dry completely. Leave them alone for at least 2-3 hours before wearing them again. Clean your shoes at night so you can leave them to dry overnight.

summary: Mix dish soap into 1c (240ml) of warm water. Clean the soles and rubber pieces with a magic eraser. Scrub stains with a stiff-bristled toothbrush. Pat excess water away with a towel. Let your shoes air dry.

Summarize the following:
Whereas the heart rate is simply the number of times your heart beats in a minute, the stroke volume is the volume of blood pumped out by your heart's left ventricle with each beat. It is measured in millilitres and is much more complicated to determine that your heart rate. A special test called an echocardiogram (aka echo) is used to determine your heart's stroke volume. An echocardiogram uses radio waves to create a picture of your heart so the volume of blood passing through it can be measured. An echocardiogram makes it possible to make the measurements of the heart that are required to calculate stroke volume. Using the echocardiogram, you will be able to determine the numbers needed for the following calculations. The left ventricle outflow tract is the portion of your heart through which blood passes to enter your arteries. In order to calculate the stroke volume you will need to determine the area the left ventricular outflow tract (LVOT), and the velocity time integral of the left ventricular outflow tract (LVOT VTI). These calculations need to be done by a professional reading an echocardiogram. An expert may use the following equation to determine the area of the left ventricle's outflow tract: Area = 3.14 (LVOT diameter/2)^2 This way of calculating the area is now beginning to be superseded by more advanced imaging technology. To determine stroke volume, the amount of the blood in a ventricle just before a beat (end-diastolic volume, EDV) is subtracted from the amount of the blood in a ventricle (heart chamber) at the end of a beat (end-systolic volume, ESV). Stroke Volume = EDV ESV. While stroke volume usually refers to the left ventricle, it can also refer to the right ventricle. The stroke volume of both ventricles is usually equal. To determine your stroke volume index, take the velocity time integral, which is the amount of blood being pumped with each heartbeat and divide it by the body surface area of the left ventricle (in square meters). This formula allows direct analysis of the stroke volume for a patient of any size. Finally, to determine your cardiac output, multiply your heart rate by your stroke volume. This is a relatively simple calculation which identifies the amount of blood your heart pumps in one minute. The formula is Heart Rate x Stroke Volume = Cardiac Output. For example, if your heart rate is 60 bpm and your stroke value is 70 ml, the equation looks like this: 60 bpm x 70 ml = 4200 ml/min or 4.2 liters (1.1USgal) a minute.
summary: Have an echocardiogram. Calculate the area of the left ventricle's outflow tract (aka LVOT). Assess stroke volume. Determining your cardiac output.
