The spectrum is no haemoglobin spectrum, but a cytochrome spectrum of reduced cytochromes, i.e. the tissue is no longer supplied by oxygen.

Generally it's a good idea to ignore most of the specifications listed with headphones. It may sound a little unusual and you might consider it hard to choose headphones without something to go by, but the only product information that really matters are details like whether the headphones are circumaural or supra-aural, whether they're open or closed, how heavy they are, how long the cable is (or range if theyr'e wireless), what kind of earpads they have and perhaps impedance.

We provide frame measurements so that you can choose frames that are the best fit for you. If you already wear glasses, the best way is to note down the measurements of your current pair to give you a guide. The arm length and bridge width will determine the fit and comfort of the frames. The frame width is down to individual preference. As a general rule of thumb, people with narrow faces suit narrow frames.

Do not take the measurements yourself. Ask a friend to help you or have your measurements taken by a professional tailor or seamstress.

Please see our How to Measure page for more details.

This chart can help convert dosages cited in studies between international units (IU) and milligrams (mg). For example, 400 IU of synthetic dl-alpha-tocopherol is converted to 363 mg dl-alpha-tocopherol by dividing 400 IU by 1.10.

There's no official name for the non-metric U.S. system of weights and measures, but the most commonly used terms are: customary system" or "customary units" or "customary weights and measures" (Metric Act, 1866; Mendenhall Order, 1893; NIST SP 345, A Metric America: A Decision Whose Time Has Come, 1971) If it's not obvious from the context, it's wise to distinguish the U.S. system from others: "U.S. customary system.

The Friendly Enzymes are measured using measurements established by the Food Chemicals Codex (FCC). The FCC is published by the National Academy Press which is funded by the Food and Nutritional Board of the National Research Council (an appendage of the FDA).

Balance: The midpoint along the racket as measured from butt to head is used as the starting point to measure balance. If the racket is evenly balanced, its weight will be evenly distributed on either side of the midpoint, so that if you hold the racket parallel to the floor between your thumb and forefinger at this point, the racket will hang evenly. If the racket is head heavy, more weight is at the head end and the racket will have more swing weight.
