Basic 7S globulin (Bg) is a raethionineand cysteine-rich glycoprotein which occurs in soybean seeds (1). The mature Bg is composed of highand low-kDa subunits which are linked by disulfide bonding. Bg is synthesized in the cotyledons during seed development. We isolated a cDNA clone (pBG 108) (sequence below) encoding Bg by using oligonucleotide probes which were constructed on the basis of ami...

In this paper we study a large market in which sellers compete by offering auctions to buyers instead of simple fixed price contracts. Two variants of the model are studied. One extends a model first analyzed by Wolinsky (Rev. Econ. Stud. 55 (1988), 71 84) in which buyers learn their valuations only after meeting sellers. The other variant extends the model of McAfee (Econometrica 61 (1993), 12...

Austrian, Robert (The University of Pennsylvania School of Medicine, Philadelphia), and Patricia Collins. Importance of carbon dioxide in the isolation of pneumococci. J. Bacteriol. 92:1281-1284. 1966.-Of the strains of pneumococci isolated from man, 8% manifest a requirement for CO(2) if detectable growth is to occur on the surface of solid media. The pneumococci most frequently manifesting th...

Abstract This article surveys measurements of celestial (chiefly solar) altitudes documented from twelfth- and thirteenth-century Latin Europe. It consists four main parts providing (i) an overview the instruments available for altitude described in contemporary sources, viz. astrolabes, quadrants, shadow sticks, torquetum; (ii) a survey role played by determination geographic latitude, which t...
