Transfer the sample extract (from Section 6.1) into a 200-mL separatory funnel, add 30 mL of water and extract the sample extract three times with 30 mL of n-hexane. Collect and dry the n-hexane layer with anhydrous sodium sulfate in a funnel in a similar manner as described for the juice, pulp and rind, and evaporate the solvent under reduced pressure. Dissolve the residue in 3 mL of benzene and clean up the sample by silica gel column chromatography in a similar manner as described for juice, pulp and rind. 

Expression is the use of a crushing, mechanically applied pressure to squeeze oils from plant material. It was originally done by hand but is now mechanized, with use of centrifugal separators. Expression is used almost exclusively for citrus fruits with oil glands in the outer rind of the fruit. 

Paleosols. Paleosols formed before 2.2 Ga tend to contain iron silicates, rather than siderite-iron carbonate. Rye et al. (1995) used carbonate-silicate mineral equilibria in the 2.75 Ga Mount Roe paleosol to estimate the partitioning of COa between soil and air in the late Archaean. Their calculations suggest a maximum partial pressure of 10 14 (0.04) atmospheres COa in the late Archaean atmosphere, significantly lower than the estimate of Lowe and Tice (2004) based on nahcolite. A lower limit for atmospheric COa comes from the study of siderite-clay mineral equilibria for weathering rinds on clasts in river gravels from the 3.2 Ga Moodies Group of the Barberton greenstone belt, in south Africa (Hessler et al., 2004). In this study the minimum partial pressure for atmospheric COa at 3.2 Ga was calculated to be 2.5 X 10 3 bars at 25°C. 

Geranial, also called citral, is an example of an aldehyde which contains two double bonds. It is an important constituent of various essential oils, among which are those derived from lemons, geraniums, roses, and orange-rind. It is a liquid, which possesses an agreeable odor and boils at 110°-112° under a pressure of 12 mm. An interpretation of the methods used in its synthesis and of its reactions leads to the conclusion that its structure is represented by the formula,—... 

Mechanical properties of hydrogenated titanium alloys are strongly dependent on the applied stress tensor, especially on its hydrostatic component. This was illustrated by the high-pressure tensile rind extrusion tests on the Ti-6Al-2.5Mo-2Cr alley and the same alloy hydrogenated to a = 0.15 wt.%H. Tests were carried out using the apparatus at the Institute of Metal Physics UD RAS operating at hydrostatic pressmes of machine oil to 15 kbar and temperatures to 250°C. 

Water pressures supplied from a moat ringing the dome, and elevated by topography to 50 m of head, and also those generated by incursion of a saturated rind to a depth of 50 m, are shown to have negligible impact on stability. However, also clear is that for the selected strength parameters, the larger dome is only metastable, and little disturbance is needed to induce failure. Regardless, the incursion of rainwater to 50 m is considered improbable. 

For the same strength parameters as previous, the unpressurized small dome is stable, but may be brought close to instability by steady core pressures of the order of 5 MPa. Minor augmentation by uniform rind-trapped pressures of the order of 0.2 MPa is sufficient to promote low-angle failure to as shallow as 40° and remove about 20% of the edifice on one side. Alternatively, if effusive gas discharge is flux, rather than overpressure-controlled, a three-order of magnitude (x5(X)) reduction in permeability in a rind of 5 m will... 

Equation 2.2 shows that D is determined by the interplay of the thermodynamic factor dH/dc and the friction factor /. In general, the friction factor is expected to increase monotonically with increasing c rind decrease with rising temperature. On the other hand, as can be deduced from the known information about osmotic pressure, the thermodynamic factor as a function of c varies in complex ways with solvent quality and temperature. Thus, the concentration dependence of D for a given polymer should exhibit a variety of features depending on solvent conditions. 

Kitchen-etuff, as prepared by the Btuff-melters, is a very useful material for mottled soaps, and is largely used by the London soap-makers for this purpose. Being the produoe of Mtchen waste it contains many difierent kinds of fatty matter, hut after its separation from the more solid particles, as gristle, rind, bones, fibrin, etc., by pressure, it forms an uniform fatty mass of good consistency, and oontainB a considerable proportion of stearine, whioh renders it well suited to the manufacture of a curd soap such as the London mottled soap. 

In a general way, the coefficients of the Landau equation are functions of pressure. When pressure is varying, b may decrease, in magnitude, and the temperature hystere.sis diminishes according to Equation 35 rind disappears at 6 = 0.
