Abstract.- The behavior of iron atoms in calcium-silicate glasses has been studied by the Mossbauer effect. The equilibrium concentration ratio, NFe3+/NFe2+> increases as the CaO content or the partial oxygen pressure during heat treatments increases. In the glasses containing a large amount

with low melt viscosities and high Tgs: effects of the molecular weights Cao-ning Su, Mian Ji, Lin Fan and Shi-yong Yang Phenylethynyl-endcapped imideoligomers (oligomides) with low melt viscosities and high glass transition temperatures (Tg) were prepared by the high temperature polycondensation

This report focuses on the evidence about the health.consequences of smoking for women, and is intended to serve.the public health and medical communities as 'a unified source of existing scientific research. The major issues about tobacco use and women's health are examined, including trends in consumption, biomedical evidence, and determinants of smoking ititiation, maintenance, and cessation. The biomedical aspects ofsmoking are presented in terms of mortality, morbiplity, cardiovasculaidiseases, cancer, pregnancy and infant,health,, Teptic ulcer disease, drug reactions and, interactions, food constituents, and responses to,diagnostic tests. The psychosocial and behavioraj. aspects, of smoking in women are discussed, along with the docffiented increases in- the risk of contracting lung cancer, heart,disease, or lung disease. The harmful effects of pregnant mothers smoking behaviors, are also docudented. Adhitionally, recent data are enumerated to indicate a trend of,decreasing tobacco usage among women in response to the warnings of the gavernMent, voluntary agencie, and physicrins.
