Ecker, R. E. (Iowa State University, Ames), and W. R. Lockhart. Relationships between initial nutrient concentration and total growth. J. Bacteriol. 82:80-84. 1961.-The relationship observed between maximal attainable growth in a microbial population and initial concentration of limiting nutrient depends upon the parameter selected for measurement of growth. A linear relationship is found only ...

abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...

Plants use the gas ethylene (C2H4) as a signaling molecule for regulating a variety of developmental processes, including fruit and flower senescence, sex determination in some monoecious species, cell elongation and pathogen responses [1]. The final reactions of the ethylene biosynthetic pathway have been elucidated [2], and information on its signaling apparatus is beginning to emerge [3,4]. ...
Complications of basilar skull fracture, such as carotid cavernous fistulae, meningitis, cerebrospinal fluid rhinorrhoea and otorrhoea, pneumatocele, and various cranial nerve disturbances, are well known (Gurdjian and Webster, 1958). In -addition, unilateral thrombosis of the internal carotid artery, both with and without basilar skull fracture, has frequently been reported after closed head a...

The induction of oocyte maturation: transmembrane signaling events and regulation of the cell cycle.
The induction of oocyte maturation is known to involve an initial action of agonists at the oocyte surface. This leads to activation of a cytoplasmic maturation-promoting factor (MPF) which induces the observable events associated with maturation (reviews by Smith and Ecker, 1970; Smith, 1975; Wasserman and Smith, 19786; Baulieu et al. 1978; Masui and Clark, 1979; Mailer and Krebs, 1980; Mailer...
