The temperature of the system is proportional to the average kinetic energy (eq. (16.12), and therefore determines which parts of the energy surface the particles can exploit. Owing to the finite precision by which the atomic forces are evaluated, and the finite time step used, the total energy in practice is not constant (preservation of the energy to within a given threshold may be used to define the maximum permissible time step). 

Figure 46-8. Fusion of a vesicle with the plasma membrane preserves the orientation of any integral proteins embedded in the vesicle bilayer. Initially, the amino terminal of the protein faces the lumen, or inner cavity, of such a vesicle. After fusion, the amino terminal is on the exterior surface of the plasma membrane. That the orientation of the protein has not been reversed can be perceived by noting that the other end of the molecule, the carboxyl terminal, is always immersed in the cytoplasm. The lumen of a vesicle and the outside of the cell are topologically equivalent. (Re drawn and modified, with permission, from Lodish HF, Rothman JE The assembly of cell membranes.

In addition to their tremendous value as arehives of information about the past state of the Earth s environment, speleothems have an aesthetie value that satisfies the euriosity of all eave visitors. For this reason, we promote eonservation guidelines that have been set in plaee to preserve the quahty of cave environments. In many regions of the world, collection of speleothems is prohibited by legislation. Even if permission is obtained, the utmost effort should be made to minimize the impact of sampling. 

Figure 4. Modeled U-series date profiles across a 10 ky bone according to the D-A model under constant conditions. The dates are calculated using the closed system assumption. The parameter D/R is the diffusion-adsorption parameter and is related to the water content of the soil, the state of preservation of the bone and aspects of the geochemistry of the burial environment.

Figure 11.6 Plot of the difference (A value) between the 513C values of stearic (Ci8 0) and palmitic (C16 0) acid against the 513C value of stearic acid (Ci8 0). The data points represent samples extracted from Early Neolithic pottery in the study published by Craig et al., 2005. A values below —3.3%o are interpreted as ruminant dairy. The inset shows the range and abundance of triacylglycerols preserved in the Early Neolithic vessels from Ecsegfalva, Hungary, (from Craig et al., 2005 Figure 3b, by permission of Antiquity Publications Ltd.)...

The original, historic specimen of columbite is preserved in the British Museum (67). A portion of it was used by Charles Hatchett in 1802 in his famous research which culminated in the discovery of columbium. In 1809 Dr. W. H. Wollaston obtained permission to detach another portion of it for an investigation, from which he incorrectly concluded that columbium and tantalum are identical (68).

Beef was obtained from cattle supplemented with 0 (E-0), 500 (E-500) or 2000 (E-2000) IU a-tocopherol acetate per head per day. The a-tocopherol demonstrated a color preservation effect. Hue angle was calculated as [tan-1(b7a )] (36072rc). Standard error bars are indicated. Adapted from Chan et al. (1995), with permission from the Institute of Food Technologists.

In Japan, the term additive means anything added to, mixed with, permeating, etc., food in the process of manufacturing, processing, or preserving it [8], In Japanese food law, synthetic and naturally occurring additives are treated differently. The latter, especially naturally occurring flavors and vitamins, do not require any special permission for use. This explains, for example, why sweeteners isolated from plants must be specifically permitted as additives everywhere else in the world, while they can be used freely in Japan. 

Figure 4.3 Two examples of a 27t-spectrometer collecting electrons within a plane, (a) Suggested set-up with full rotational symmetry around the symmetry axis z. The electric field is supplied by conical bodies, and the detector collects simultaneously all electrons emitted from the source Q into the plane perpendicular to the z-axis (for directional information of electron emission using a discretised detector, see below). From [Kuy68]. (b) Spatial view of a toroidal analyser. The outer and inner toroids which again possess axial symmetry provide the electric field. The detector is a position-sensitive detector (see Section 4.3.2) which records directional information about the electron emission. Hence, the angle dependence of electron emission from the source Q into the plane perpendicular to the symmetry axis is preserved. See also [EBM81, Hue93]. Part (b) reprinted from Nucl. Instr. Meth.

In the end, I decided to use interview material as primary evidence only rarely. Wherever possible, I have used material sources or interviews with other scientists to verify the accuracy of scientists statements of fact. In instances where I ve been unable to locate supporting evidence for important claims, I note that as well. To preserve scientists confidentiality, I identify the interviewee only in a few cases, where not doing so would add confusion. In those cases, I have received the interviewees explicit permission to cite them directly.

GxP regulations require that access to the software and relevant associated documentation should be preserved for a number of years after the system or software has been retired (see Chapter 4 and Chapter 11 for more details). Software licenses do not entitle pharmaceutical and healthcare companies to ownership of the software products they have purchased. All that has been purchased is a license, an official permission or legal right to use it for some period of time under defined conditions of use. Accordingly, some companies have established escrow (third party) accounts with suppliers to retain their access to software, but this is not mandatory. Access agreements directly...
