Change of occupation

Equation 9 and Eq. 4, however, consider only the rates of changes of occupancy states and assume that the channel itself is a constant unchanging entity. But the... 

In words, this states that the rate of change of occupancy is simply the difference between the rate at which ligand-receptor complexes are formed and the rate at which they break down. ... 

This is proportional to the rate of change of occupancy of our tube with time. We can now use this function to describe our shearing behaviour ... 

The expression (42) takes into account the response of the f-th orbital to the change of occupation number of the j-th orbital, i.e., the variation of energy of the f-th orbital due to the variation of the j-th occupation number [48]. 

In considering changes of occupation number in two different orbitals a) and j8) we characterise the configuration p) by two occupation numbers and n. ... 

The treatment of chronic bronchitis is quite similar to that for emphysema. Because cigarette smoking and air pollution are common causes of these two diseases, the therapeutic treatment of both diseases begins with discontinuing exposure to such exacerbating agents. This may necessitate a change of occupation or relocation to a more favorable climate. 

Thus the second term in Eq. (27) is canceled by the derivative of electronic entropy and the first term is -d(E-j- - T, S, )/dR,. The inclusion of electronic temperature effects not only avoids the instability caused by the change of occupancies of states near the Fermi level in metallic systems, but also includes the effects of electronic entropy into the calculation in a very convenient manner. 

Opinions are divided with respect to the effect of change of occupation. It should be mentioned, however, that the majority of those who changed their work had the most pronounced contact dermatitis, which may explain the persistence of the disease. 

Table 1. Change of occupation among atopic dermatitis patients according to Lammintausta et al. (1993). The initial and new occupations of 111 individuals are indicated. The reported prevdence of hand eczema (HE) in 955 atopic dermatitis patients with the same occupations is also shown (Rystedt 1986a)...

Petrenz (1844) complained of the nearly complete lack of information on quarriers disease in scientific papers and reference books. Practising medicine at Schandau in the mountain range on the Elbe river in Saxony, he was well-acquainted with this fatal disease. He advised a minimum age of 25 years for admission to the profession, wetted sponges to prevent the dust from entering the respiratory system, and change of occupation in case of respiratory disease. 

In order to formulate the excitation lifetime and the quantum yield in terms of transfer rates, we first introduce a master equation for the rate of change of occupation probabilities of chlorophylls. In the discussion below, a single excitation will be assumed to be localized at one of the chlorophylls and the effects of excitonic delocalization will be ignored. As a specific example we shall consider the case of excitation migration in cyanobacterial PSI ( ener et al, 2002b 2004). 

Fig. 5. Change of occupancies (s-, p-and d-character) with pressure. The corresponding ranges for the stable structures are indicated. 4f-electrons are treated as core in this case.

Another physical phenomenon connected also with the change of occupation number of ground state and consequently with an incident power dependent refraction index variation (cf. Heeger et al. (I986)) is photoinduced absorption observed in polyacetylenes (Orenstein and Baker (1982)), polydiacetylenes (Orenstein et al. (198 )) and polythiophenes (Moraes et al. (198 )). In this process (cf. Fig. 20) with the pump at (o energy corresponding to the first allowed one photon transition one varies refractive index in both visible (o) ) and infrared frequencies. 

Let us call pio (probability of input/output) the probability of making this kind of trial. Then, if a random number within the interval [0,1) is smaller than pio, a change of occupation is attempted. In this way, one of the M adsorption sites is selected at random with probability 1 /M. By dehning the matrix element surface(/, j), such that it contains the occupation state of the site (/, j), one has that ... 

The probability of occurrence of a diffusion event is complementary to that corresponciing to the change of occupation, namely.
