Hayashi effect

The Hayashi track (Hayashi 1961, 1966) is the locus of fully convective stars in the HR diagram, dependent on the mass, luminosity and chemical composition. However, it is mainly the surface properties - luminosity and radius or luminosity and effective temperature - that govern the entire stellar structure by fixing the adiabatic constant. A sketch derivation of its properties is the following. 

In the interior, we can apply the global version of the hydrostatic equation (5.8) 

At the surface, there is another (local) hydrostatic condition

Several studies provide information regarding body weight effects of lead in animals (Dieter et al. 1993 Freeman et al. 1996 Hamilton and O Flaherty 1995 Hayashi et al. 1993 Kala and Jadhav 1995a Skoczynska et al. 1993 Yokoyama and Araki 1992). Most of these studies were conducted in rats, are of intermediate-duration exposure, and used various media to administered the lead. 

Effects at even lower external and internal exposure levels were reported by Hayashi (1983). Lead acetate at 0.7 mg lead/kg/day in the drinking water of rats for the first 18 or 21 days of pregnancy resulted in decreased ALAD activity in the fetal and maternal erythrocytes and increased ALAD activity in fetal but not maternal liver. Fetal, but not maternal, hematocrits and hemoglobin levels were decreased in the group treated for 21 days. Fetal PbB levels were 27 pg/dL and 19 pg/dL in the 18-day and the 21-day treated groups, respectively. Maternal PbB levels were approximately 4 pg/dL in treated and control groups. The study is limited by the use of one dose level, which precluded assessment of dose response.

Amides and sulfonamides undergo intramolecular chemistry to form aryl amides and aryl sulfonamides (Equations (17)—(19)) in the presence of palladium catalysts ligated by arylphos-phines.35,89 Initially, complexes of P(furyl)3 and P(o-tol)3 were most effective catalysts, but complexes of Hayashi s MOP and van Leeuwen s DPEphos and xantphos have lately been shown to be more active.90 In the presence of catalysts containing one of these ligand systems, five-, six-, and seven-membered rings were formed from halogenated benzamides or from substrates containing an acetamide, an A-carbobenzyloxy, or a t-butylcarbamate substituent tethered to the aryl halide (Equations (18) and (19)) ...
