McClintock effect

This effect has been described as the McClintock effect, named after the primary investigator, Martha McClintock, at the University of Chicago (see references McClintock and Stern, 1971 and 1998). The McClintock effect, however, is still not...

In a later experiment, two pheromones from axillary odor of young women influenced the estrus cycle of other women (Stern and McClintock, 1998). Armpit secretion that appears odorless to humans was applied daily between the upper lip and nose of healthy young women and had two opposite effects depending on the menstrual phase of the odor donors. Secretion from nine donor women, collected on pads in their armpits during the follicular phase of their cycles... 

Following the pioneering work on menstrual synchrony by Stern and McClintock [270, 271], it has been odourless axillary compounds fi om the armpits of women in the late follicular phase of their menstrual cycles accelerated the preovulatory surge of luteinizing hormone of recipient women and shortened their menstrual cycles. Axillary compounds from the same donors which were collected later in the menstrual cycle (at ovulation) had the opposite effect they delayed the luteinizing hormone surge of the recipients and lengthened their menstrual cycle [271]. The... 

Pheromonal effects of human body secretions have been closely examined in the study of human chemical communication since the 1970s (e.g., McClintock, 1971 Russell et al, 1980 Preti et al., 1987 Weller et al., 1995 Stem and McClintock, 1998). Men s body odor has been shown to regularize women s menstrual cycle (e.g., Cutler et al., 1986). However, attempts to identify the active constituents in complex mixtures of body odors are sporadic. The available publications are mainly focused on steroids (e.g., Cowley and Brooksbank, 1991 Maiworm and Langthaler, 1992 Grammar, 1993) and the results are often ambiguous. Therefore, much has yet to be done to identify active compounds in human body secretions and their effects on women s menstrual cycle. 

In the yielding of polyerystalline ductile metals that obey symmetrical 3D yield criteria of von Mises or Tresca type (McClintock and Argon 1966) the plastic shear resistance is nearly independent of pressure and the S-D effect is negligible. In comparison it is very substantial in disordered solids, with the ratio rc/ T being in the range 1.2-1.3.

Obviously, if the tensile forces are large enough, the distance between atoms can become so great that the attractive force will tend to zero and no force would be required for the atom to be in equilibrium. On the other hand, the application of a compressive forces can not force the two atoms to merge and the repulsive force will increase without bound. For this reason, it should be possible to calculate the theoretical strength of a material if sufficient information is known about the bonding forces in atoms of a particular material. This interpretation has been used by many (see for example, (Courtney, (1990), McClintock and Argon, (1966), Richards, (1961), Shames and Cozzarelli, (1992)) to formulate nonlinear stress-strain relations, laws for creep, plasticity effects, etc. However, as far as is...
