    Notes: Abstract A population-based survey of the prevalence of major blinding disorders was conducted in three villages in central Tanzania. Overall, 1827 people overthe age of seven years old were examined. In those age seven and older, the prevalence of bilateral blindness (visual acuity in the better eye of 〈3/60) was 1.26% and monocular blindness (visual acuity of 〈3/60 in one eye) was 4.32% and the prevalence of visual impairment (visual acuity 〈6/18 but ≥3/60 in both eyes was 1.04% and in one eye was 1.75%. Corneal opacities were responsible for 44% of bilateral and 39% of monocular blindness and resulted from trachoma, measles often in association with Vitamin A deficiency, keratoconjunctivitis, and the use of traditional eye medicines. Cataracts accounted for 22% of bilateral and 6% of monocular blindness. Readily preventable or reversible causes of blindness were responsible for 65% of cases of bilateral and 46% of monocular blindness.

    Kinetics of contraction of drawn nylon 66 in aqueous phenol (1969)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 13 (1969), S. 427-436 
    Details
    ISSN: 0021-8995
    Keywords: Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: The rate of contraction of drawn nylon 66 in aqueous phenol was investigated, and a method is described for correlating this contraction with a series of elementary rate processes. The rate constants so obtained were analyzed by absolute rate theory, and the variations of ΔH† and ΔS† with phenol concentration gave evidence of the nature of the reaction steps.
