Elements proportions

Figure 1. Thermodynamic equilibrium in atmospheres of varying elemental proportions. The ternary diagram shows all compositions of systems containing carbon, hydrogen, and oxygen (each point represents 100% of the three components). Lower curves indicate the potential formation of solid carbon if equilibrium could be attained. Dashed curve holds at 500°K., the continuous one at 700°K. The upper lines indicate the asphalt threshold, the dashed one at 500° K., and the continuous one at 700° K. Above this threshold, thermodynamic equilibrium favors the formation of large proportions of polycyclic aromatic compounds ( asphalt ) ana a lesser increase of most of the other families of compounds. The dots through points A to C indicate the points used in the computations for Figure 2 (6). Figure 1. Thermodynamic equilibrium in atmospheres of varying elemental proportions.

The elements of the matrix g diagonal in the particle-hole space (i.e proportional to to and T3) are related to the normal Green s function, while the off-diagonal elements (proportional to t 1 and ) determine the superconducting condensate function /. In the case under consideration the matrix g can be expanded in the Pauli matrices in the particle-hole space (f0 is the unit matrix) ... [Pg.231]

GemaB Gl. 1 laBt sich das Alter einer Probe aus der zur Zeit t noch vor-handenen Anzahl der Atome eines radioaktiv zerfallenden Elements be-stimmen. Da die durch die Zahl der a-, (3- oder y-Zerfalle Z (z. B. pro Minute) gegebene Radioaktivitat eines Elements proportional der Anzahl vorhandener Atome ist (M, Z, M0 Z0), folgt aus Gl. 1 fiir das radioaktive Alter der Probe ... [Pg.12]

Nearly all binary molecular compormds involve two nonmetals bonded together. Although many nonmetals can exhibit different oxidation numbers, their oxidation numbers are not properly indicated by Roman numerals or suffixes. Instead, elemental proportions in binary covalent compounds are indicated by using a prefix system for both elements. The Greek and Latin prefixes for one through ten are mono, di, tri, tetra, penta, hexa, hepta, octa, nona, and deca. The prefix mono- is omitted for both elements except in the common name for CO, carbon monoxide. We use the minimum number of prefixes needed to name a compound unambiguously. The final a in a prefix is omitted when the nonmetal stem begins with the letter o we write heptoxide, not heptaoxide. ... [Pg.163]

Laser granulometry indicated little variation in the particle size with depth in the trench section, the median size being 12-15 pm. On average the bulk sediments were found to contain approximately 20% clay ( < 2 pm), 70% silt (2-63 pm) and < 10% sand ( > 63 pm). Bulk sediment XRF analyses also showed that the major element proportions are also relatively constant with depth (Figure 7.7). X-ray diffraction (XRD) analyses showed some variability in the relative proportions of clay minerals present in the < 2 pm fraction, but all samples were dominated by illite, smectite, kaolinite and chlorite. The calcium carbonate content was low ( < 1%), much of the detrital material apparently having been dissolved. The sediment pH ranged from 6.2 to 6.7. [Pg.130]

Further, it follows from the Wigner-Eckart theorem that two tensorial sets of operators of the same degree, ip and Q have their matrix elements proportional to one another. [Pg.275]

Is the perturbation matrix element J-dependent (heterogeneous perturbation or S-uncoupling in either the perturbed or perturbing state) Figure 5.8 contrasts the level shifts resulting from J-independent perturbation matrix elements with those from matrix elements proportional to J. [Pg.296]

The symbols s and a (standing for symmetric and antisymmetric) refer to the parity with respect to inversion. In this basis, 3fd has only diagonal matrix elements. The operators and 8 e off-diagonal elements proportional to the parameters a and p, respectively, which are defin by ... [Pg.327]

The proportions of the X-ray counts in the peaks of the spectra are not the same as the elemental proportions in the minerals. [Pg.153]

This technique is used near surface elements to estimate the elemental proportion at different position confirming the overall elemental mapping. [Pg.57]

Through this procedure, the individual structural units of the three monuments have been analysed and the strengthening elements proportioned. The results for the three monuments are given in Sects. 8.4.1, 8.4.2 and 8.4.3. [Pg.127]

Note that we have introduced nucleon field operators N instead of quark operators to express simply the nucleon contribution to The first term in (10.3.12) is negligible since the nuclear matrix element will be proportional to the nuclear spin and therefore small, whereas the second term, which non-relativistically is dominated by the 70 component, gives rise to a coherent nuclear contribution, with matrix element proportional to... [Pg.196]

The cross-linked structure of rubber vulcanizates, because of their insolubility and for other reasons, are difficult to analyze directly beyond providing information on elemental proportions. Nevertheless using a variety of approaches it has been possible to acquire more and more knowledge of the structure of diene rubbers, natural rubber in particular. [Pg.205]
