Studies on the expression and modulation of gap junctions in rat myometrial cell cultures
(1993)
The expression and modulation of myometrial gap junctions remain poorly understood. However, the availability of new molecular and biochemical tools including cDNAs and antipeptide antibodies permits extensive characterization ...
Total factor productivity in Mexican manufacturing : an analysis of the sources of growth, 1975-85
(1993)
This study provides an analysis of the effects of Mexico's industrial development policies on the structure and productivity of its manufacturing base between 1975 and 1985. Because virtually every aspect of the economy ...
Developmental regulation of heat shock proteins : 70.1 in murine embryos and 70.1 and 70.4 in bovine embryos
(1993)
Heat stress causes embryonic mortality in the bovine and in the mouse. A group of proteins known as heat shock proteins (HSPs) are synthesized in response to heat stress and are thought to enhance cellular thermotolerance. ...
Antiestrogenic and antimitogenic effects of 2,3,7,8-Tetrachlorodibenzo-para-dioxin (TCDD) : in vitro mechanistic studies
(1993)
2,3,7,8 -Tetrachlorodibenzo-p-dioxin (TCDD) is a broad spectrum antiestrogen which works through the aryl hydrocarbon (Ah) receptor. The estrogen receptor (ER) positive hum an ovarian carcinoma cell lines PE01, PE04 and ...
Selective alkylation of toluene with methanol over pentasil-type catalysts
(1993)
Para xylene is a valuable aromatic compound, because of the demand for oxidation to form tetraphthalic acid, a feed stock for polyester resin and fibers. A relatively high cost is associated with obtaining it in 99+% purity. ...
Why are calls of convertible preferred stock delayed? : tests of the passive investor hypothesis and the call faliure hypothesis
(1993)
Ingersoll (1977a) and Brennan and Schwartz (1977) show that, in perfect markets, managers maximize common stockholders' wealth by calling a convertible security as soon as its conversion value exceeds its call price. ...
An adaptive hybrid neural network approach for learning nonstationary manufacturing processes
(1993)
An adaptive hybrid learning procedure is proposed for change detection and on-line identification of nonstationary manufacturing processes. Sequential measurements in manufacturing systems and on-line measured signals in ...
Social-cognitive processing in aggressive/withdrawn, aggressive/nonwithdrawn, and nondeviant children
(1993)
The purpose of this study was to further investigate subtypes of aggressive children by examining the classroom behavior, social-cognitive, self-control and self-concept differences between aggressive/withdrawn, ...
