CALCULATIONS 5.1 Calculate the percentage of each or a combination of deleterious materials: PDW ï½ï´100 Where: P = Percentage of deleterious matter by weight D = Weight of deleterious substances, g W = Weight of total sample (retained on No. 4 [4.75 mm] or No. 8 [2.36 mm]), g.est the material retained on the No. 8 (2.36 mm) sieve for compliance with the specification requirements if the sample contains an aggregate that predominately passes the No. 4 (4.75 mm) sieve. 8.7 Remove any material other than coated particles of aggregate that will slake down during the test.
OcuviteÂ® is a supplement made from natural ingredients that is thought to help with macular degeneration caused by the aging process, as well as some degenerative eye diseases.
Lutein is a naturally-occurring carotenoid that is abundant in fruits and vegetables (especially dark, leafy green ones) and egg yolks, and it is highly concentrated in the macula of the eye, with smaller amounts found in the retina, lens, and optic nerve.esearch has also shown that lutein can lower risk of cataracts. For example, one study found that older women who had the highest levels of lutein (and zeaxanthin, another nutrient that is critical for vision health) were about a third less likely to have cataracts.
