Gastric acidity is the term used to refer to the acid content of the stomach. Most of this acidity is due to the presence of hydrocholoric acid secreted by the mucosa (lining) of the stomach. The clinical laboratory can make two kinds of determinations involving gastric acidity: the concentration of acid in the stomach contents and the rate of acid output by the mucosa. Sorensen developed a scale to use in measuring the H+ concentration.

We also do not charge any additional setup fees or travel fees. I feel confident that our testing protocols will save you money as well as production time. See similar questions...

Many studies done by experienced laparoscopic bariatric surgeons have demonstrated laparoscopic gastric bypass to be safe. A study done by Dr. Oliak (see Description of Surgeries section) demonstrated the importance of surgeon experience. He found complication rates to be significantly higher during the "learning curve" for laparoscopic gastric bypass. Complication rates stabilize at a low rate after a surgeon completes approximately 75 laparoscopic gastric bypass operations. See similar questions...

Laparoscopic gastric bypass is a difficult operation to learn to do safely. It also takes longer and is more expensive. The result is that most gastric bypasses in the United States are done open at this time. For most patients laparoscopic surgery is better (less pain, shorter hospital stay, less scarring, quicker return to usual activities). As more surgeons learn to do laparoscopic gastric bypass safely and patients demand it, more laparoscopic gastric bypasses will be done. See similar questions...

In the adjustable gastric banding method a band is applied around the stomach about 20 mm below the gastro-esophageal junction. On the inner lining of the band there is a longitudinal balloon (like a bicycle tire). This balloon is through a small tube attached to a subcutaneous port. The band is left empty at time of surgery but is thereafter gradually filled with fluid by injection through the subcutaneous port. It is thus possible to vary the opening in the stomach after surgery. See similar questions...

Laparoscopic gastric bypass is accomplished with 5 small incisions rather than one long incision. A camera is placed through one of the incisions and long instruments through the others. The operation is performed while watching a video screen. The actual operation on the stomach and intestine is the same with both approaches. See similar questions...

Laparoscopic gastric bypass results in a shorter hospital stay, less pain, less scarring, and a quicker return to usual activities. Complications such as wound infections and wound hernias are nearly eliminated with the laparoscopic approach. The risk for serious complications (such as leak) is similar with both laparoscopic and open gastric bypass. See similar questions...

Coffees are described using a wide array of terms, but the most important are flavor, acidity and body. Flavor refers to the overall experience of drinking a particular coffee, which includes both taste and aroma. Specific flavor attributes can be found in certain coffees, such as a chocolate-like taste or a nut-like aroma. Acidity is another important, though often misunderstood, term.

Acidity is the one test that defines fluid life. The additive package contains an agent to control acidity, which usually keeps the level under 0.5 mg KOH/g. When acidity reaches the range of 1.0 to 1.5 mg KOH/g, it means the additive that controls it is severely depleted. The maximum permissible acidity level is 1.5 mg KOH/g. Some manufacturers set lower limits. Consult Solutia Technical Service for further details. In many cases, when a fluid reaches 1. See similar questions...

In order to establish the effectiveness of a hearing protector, the following method (with certain modifications) is used by all current standards. Ten subjects are exposed to sounds at 9 different frequencies (tones) and the lowest sound level that can be heard is established. The subjects are tested three times for each frequency, resulting in 27 individual sets of data. Thereafter each subject uses a hearing protector, and the procedure is repeated.

EMG is measured using similar techniques to that used for measuring EKG, EEG or other electrophysiological signals. Electrodes are placed on the skin overlying the muscle. Alternatively, wire or needle electrodes are used and these can be placed directly in the muscle. See similar questions...

During your first few visits your therapist is likely to perform a detailed clinical evaluation.This not only helps in assessing your complaint but also enables us to keep a check on how things progress. However the 'key 'barometer' is you! We generally expect most patients to feel a significant improvement within the first treatment or two, certainly within three or four visits. If this is not the case we will discuss how we consider it would be best to proceed. See similar questions...

There are two prefered points to measure vehicle ride height. Both measurements should be taken on a level flat surface. One is at the center of the fender well to the ground.The other is at the bump stop to the axle housing or frame.. See similar questions...

Atomic clocks are the most precise devices to measure time. Atomic clocks such as rubidium, hydrogen, ammonia, and cesium clocks are used by scientists and engineers when computing distances with Global Positioning Systems (GPS) and measuring the rotation of the Earth. The most stable measurement clock that is used as the standard for the second is the cesium-133 atomic clock. See similar questions...

Carotenoids are typically measured by invasive techniques requiring blood samples or urine tests. These tests are expensive and may take weeks before you receive your results. Also, these tests may only reflect what was recently consumed, i.e. the previous meal. The BioPhotonic Scanner is a great way to measure your carotenoid level safely and non-invasively.

The standard method for testing fill is to put one ounce of down in a standardized testing cylinder and compress it with a standardized piston that fits loosely inside the cylinder. The volume occupied by this partially compressed down is the fill power measurement. To be tested properly the down must be prepared according to a set procedure, and at a defined range of temperature and humidity. See similar questions...
