    Community-based intervention programs for trachoma control (1988)
    Springer
    International ophthalmology 12 (1988), S. 19-23

    Notes: Abstract Trachoma continues to be a leading cause of blindness largely confined to developing countries. Trachoma control programs have primarily been oriented to drug therapy, an approach which may be successful if it is community-based. However, the costs to ensure long-term success are substantial. Community-based health education approaches to reduce risk factors currently provide the most promising approach for long-term trachoma control.

    Prevalence and causes of vision loss in central Tanzania (1991)
    Springer
    International ophthalmology 15 (1991), S. 123-129 
    Details
    ISSN: 1573-2630
    Keywords: blindness ; cataracts ; corneal opacity ; Tanzania ; trachoma ; visual impairment

    Topics: Medicine
    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.

    Etiology of corneal opacification in central Tanzania (1993)
    Springer
    International ophthalmology 17 (1993), S. 47-51 
    Details
    ISSN: 1573-2630
    Keywords: blindness ; corneal opacification ; keratoconjunctivitis ; measles ; trachoma ; vitamin A deficiency
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract The frequency and causes of visually significant corneal opacification in central Tanzania was assessed by a population-based survey. The overall prevalence of bilateral corneal opacification was 1.16% (95% CI 0.31–1.44) and unilateral corneal opacification was 2.07% (95% CI 1.55–2.73). Bilateral corneal opacification was most frequently associated with trachoma, keratoconjunctivitis, vitamin A deficiency and measles. Unilateral corneal opacification had similar causes with the addition of cases caused by trauma. Corneal scarring is a frequent occurence in this region. The majority of cases of corneal opacification are secondary to potentially preventable or treatable causes.

    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.
