According to Barnes and Stoner [8] dialkyltin (and -lead) compounds in mammalian systems are inhibitors of the enzymes o -keto acid oxidases by interference with the physiological function of a dithiol compound, the coenzyme -lipoic acid. The same mechanism may apply for the antimicrobial activity of these compounds. It remains, however, remarkable that their antifungal activity is rather low, whereas in particular... 

The exponent m cannot be regarded as a fitting parameter but depends on the symmetry of the system. In most cases, m = 3/2 [16, 140, 158, 166, 167, 174, 175], but m = 2 for highly symmetric systems, such as aligned Stoner-Wohlfarth particles. In particular, the m = 3/2 law is realized for misaligned Stoner-Wohlfarth particles and for most domain-wall pinning mechanisms [5], Experimental values of m tend to vary between 1.5 to 2 [136, 158]. Linear laws, where m = 1, are sometimes used in simplified models, but so far it hasn t been possible to derive them from physically reasonable energy landscapes [5, 16, 176]. The same is true for dependences such as /H- l/H0 [177], where series expansion yields an m = 1 power law.

Stoner et al. (1974) have proposed a mechanical model for postmortem striated muscle it is shown in Figure 8-28. The model is a combination of the Voigt model with a four-element viscoelastic model. The former includes a contractile element (CE), which is the force generator. The element SE is a spring that is passively elongated by the shortening of the CE and thus develops an...

There are several mechanisms that fit these facts. I give only the steps up to the one likely to be rate determining (all this material came originally from the PhD thesis of Glen Stoner see Table 1.2) [13]. 

We thus have a simple model (the aufbau or building-up principle of Bohr [1] and Stoner [2]) which correctly predicts the periodic structure of Mendeleev s table of the elements. More precisely, one should state that Mendeleev s table is the experimental evidence which allows us to use an independent electron central field model and to associate each electron in a closed shell with a spherical harmonic of given n and i, because there is no physical reason why a particular l for an individual electron should be a valid quantum number angular momentum in classical mechanics is only conserved when there is spherical symmetry.

Plants may induce mechanical irritant dermatitis from delicate hairs called trichromes or hairs with tiny barbs known as glochids. Sabra dermatitis is an irritant dermatitis seen in workers who pick the fruit of prickly pears, which have small barbed bristles (Evans and Schmidt 1980). The awns of barley and other cereal grasses may cause mechanical occupational dermatitis (Evans and Schmidt 1980). Dieffenbachia (Stoner and Rasmussen 1983), daffodil (Narcissus) and hyacinth (Hyacintus) are plants with fine, needle-shaped calcium-oxalate crystals (Evans and Schmidt 1980). The irritation caused by these plants is thought to be induced both by the mechanical action of the oxalate crystal and subsequent penetration of a plant enzyme or toxin into the skin (Epstein 1990). Irritant plants have been reviewed recently by Lovell (1996). Tiny... 

Magnetic remanence, especially the squareness, provides information about coupling mechanisms between metal nanostmctures (Stoner and Wohlfarth 1948). Ferromagnetic stmctures with a random distribution of orientations offer a squareness of 0.5. In comparison stmctures with the easy axis aligned parallel to the applied magnetic field exhibit a squareness of 1 whereas with the easy axis perpendicular to the magnetic field a value of 0 (Coey 2009). A decrease of the squareness...
