Length form

The air jet textured yam process is based on overfeeding a yam into a turbulent air jet so that the excess length forms into loops that are trapped in the yam stmcture. The air flow is unheated, turbulent, and asymmetrically impinges the yam. The process includes a heat stabilization zone. Key process variables include texturing speed, air pressure, percentage overfeed, filament linear density, air flow, spin finish, and fiber modulus (100). The loops create visual and tactile aesthetics similar to false twist textured and staple spun yams. [Pg.332]

AMP-activated Protein Kinase. Table 1 Information about subunit isoforms of AMP-activated protein kinase. Data refer to the full-length forms of the human isoforms. The y2 and y3 isoforms also exist as splice variants that are N-terminal truncations, with lower molecular mass and number of amino acids (38 kDa and 328 amino acids for the short form of y2, 52 kDa and 464 amino acids for the short form of y3). Other splice variants may also exist... [Pg.70]

The Rieske protein II (SoxF) from Sulfolobus acidocaldarius, which is part, not of a bci or b f complex, but of the SoxM oxidase complex 18), could be expressed in E. coli, both in a full-length form containing the membrane anchor and in truncated water-soluble forms 111). In contrast to the results reported for the Rieske protein from Rhodobacter sphaeroides, the Rieske cluster was more efficiently inserted into the truncated soluble forms of the protein. Incorporation of the cluster was increased threefold when the E. coli cells were subject to a heat shock (42°C for 30 min) before induction of the expression of the Rieske protein, indicating that chaperonins facilitate the correct folding of the soluble form of SoxF. The iron content of the purified soluble SoxF variant was calculated as 1.5 mol Fe/mol protein the cluster showed g values very close to those observed in the SoxM complex and a redox potential of E° = +375 mV 111). [Pg.146]

The river downstream the reservoirs is about 120 km length, forms canyon meanders, and is very deep. The river widens up again at Mora d Ebre, and after crossing the littoral Catalan mountains reaches the city of Tortosa and flows to the Mediterranean Sea in the Ebro Delta (30 km). [Pg.4]

Branched chain fatty acids are present in milk (Kurtz 1974 Patton and Jensen 1976), and the following have been identified monomethyl 11-24 13-19, three or more positional isomers and multimethyl 16-28. Iverson (1983) and Iverson et al. (1965) identified the branched and other acids with the aid of urea fractionation. Saturated n-fatty acids of longer chain length form inclusion complexes with urea more readily than acyls with functional groups. The branched chain fatty acids do not form adducts. [Pg.191]

Eq. (4.3) with K = 0 may serve as starting point to find the relativistic corrections to the length form of the transition operator. The expansion of the matrix element (4.3) up to terms of order v2/c2 for the case of the... [Pg.32]

As was shown in Chapter 4 (formula (4.22)), relativistic corrections of the order a2 to the intercombination 1-transitions in length form for accurate wave functions compensate each other. It follows from formulas (4.18)-(4.20) that for the velocity form of the 1-transition operator the relativistic corrections are of the order a2 and may be presented in length, velocity and acceleration forms. Calculations of the 1-radiation for the Be isoelectronic sequence (Z = 4 92) indicate that these relativistic cor-... [Pg.360]

Another similar phenomenon is caused by radial effects. It may be estimated by the ratio of the appropriate transition radial integrals. For example, in the case of the length form of the E 1-transition it is... [Pg.375]

The ability of sulfur to form chains is also important in the sulfur vulcanization of diene elastomers such as natural rubber. In this case, strings of sulfur atoms of varying length form the cross-links that tie one chain to another. In this sense, they can be thought of as the short chains of a short chain-long chain bimodal network, as was described in Chapter 4. [Pg.277]

The fine-structure constant a indicates that first-order perturbation theory has been applied the linear dependence on the photon energy Eph is due to the length form of the dipole operator used in equ. (2.1), and the wavenumber k compensates the 1 /k which appears if the absolute squared value of the continuum wavefunction is used (see equ. (7.29)). The summations over the magnetic quantum numbers M, of the photoion and ms of the photoelectron s spin are necessary because no observation is made with respect to these substates. Due to the closed-shell structure of the initial state with f — 0 and M = 0, the averaging over the magnetic quantum numbers M simply yields unity and is omitted. [Pg.47]

The dipole matrix element on the right-hand side of equ. (8.19b) is called the length form of the matrix element, because the vector r acts as the photon operator (see the discussion of equ. (1.28a) in which the name dipole approximation is also explained). Equ. (8.16) can then be replaced by... [Pg.323]

Finally, the differential cross section for photoionization, dff/dfl, will be given explicitly for the dipole approximation and the length form of the matrix element by collecting all the individual steps. This cross section is related to the transition rate w by... [Pg.325]

One then obtains the result (see [HJC81], note that the length form of the dipole matrix element is employed here)... [Pg.328]

In the present context the two transition operators of relevance are that for photoionization which is given in the dipole approximation, and within the length form, by (see equ. (1.28a))... [Pg.343]

Unsaturated heterocyclic ligands like pyrrols or porphyrins are formally derived from secondary organic amines and their metal derivatives are therefore amide complexes. The Ln-N bond lengths formed with simple monocyclic ligands... [Pg.74]

For the evaluation of probabilities for spin-forbidden electric dipole transitions, the length form is appropriate. The velocity form can be made equivalent by adding spin-dependent terms to the momentum operator. A sum-over-states expansion is slowly convergent and ought to be avoided, if possible. Variational perturbation theory and the use of spin-orbit Cl expansions are conventional alternatives to elegant and more recent response theory approaches. [Pg.194]
