Bulge effect

In the present case, we have three distinct samples obtained by two independent groups of astronomers, two distinct folding techniques, three distinct methods of estimating maximal rotation velocities, and one method for removing bulge effects that has been tested by means independent of any of the present considerations. As we shall see, the results are not affected by any of these variations. [Pg.306]

Another problem with tube hydration systems is that, when they are full, they take on a cylindrical shape that is cumbersome on the user s back or in his racksack. This problem makes it very difficult to wear a ftill Itydration system on the back with a rucksack on top of it. Some commercial vendors have added baffles to limit the bulging effect of a full bladder. However, the baffle has limited effectiveness. [Pg.314]

The radial profiles were fit by a simultaneous minimization with respect to the four parameters the exponential disk scale length and central surface brightness, Vd and fid, and the bulge effective radius and surface brightness, and fig. Before fitting, each of the two components was convolved with a gaussian PSF, the parameters of which were determined from stars in the source frame or from standard star observations. [Pg.130]

Above approximately 80 km, the prominent bulge in electron concentration is called the ionosphere. In this region ions are created from UV photoionization of the major constituents—O, NO, N2 and O2. The ionosphere has a profound effect on radio conmumications since electrons reflect radio waves with the same frequency as the plasma frequency, f = 8.98 x where 11 is the electron density in [147]. The... [Pg.817]

Table 7-10 pre.sents a temperature conversion table for various metals from one manufacturer for conventional pre-bulged, ten-sion-loaded disks with pressure on concave side (not prescored) as an illustration of the effect of lower or elevated temperatures referenced to 72°F on the burst pressure of a stamped disk. For other types of disk designs and from other manufacturers, the specific data for the style disk must be used to make the appropriate temperature correction. [Pg.459]

In some metal components it is possible to form oxides and carbides, and in others, especially those with a relatively wide solid solubility range, to partition the impurity between the solid and the liquid metal to provide an equilibrium distribution of impurities around the circuit. Typical examples of how thermodynamic affinities affect corrosion processes are seen in the way oxygen affects the corrosion behaviour of stainless steels in sodium and lithium environments. In sodium systems oxygen has a pronounced effect on corrosion behaviour whereas in liquid lithium it appears to have less of an effect compared with other impurities such as C and Nj. According to Casteels Li can also penetrate the surface of steels, react with interstitials to form low density compounds which then deform the surface by bulging. For further details see non-metal transfer. [Pg.429]

A heat-exchanger tube is expanded into the tubeplate to effect a joint. However, to avoid bulging the tube outside the confines of the tubeplate, expansion never takes place through the whole tubeplate thickness and a... [Pg.22]

Hydrogenation of benzene to cyclohexane was effected in a fixed bed reactor at 210-230°C, but a fall in conversion was apparent. Increasing the bed temperature by 10°C and the hydrogen flow led to a large increase in reaction rate which the interbed cooling coils could not handle, and an exotherm to 280°C developed, with a hot spot of around 600° C which bulged the reactor wall. [Pg.753]

An example of miR-dependent deadenylation of mRNA measured by this method is shown in Fig. 6.3C. In this case, HeLa cells (which express let-7) were transfected with a pDNA R-luc construct encoding three let-7 binding sites in the 3 UTR (3 X bulge), or with control constructs encoding either no sites (plasmid) or three mutated let-7 sites (3 x bulge mut) (constructs described in Pillai et al, 2005). Cells were harvested 24 h after transfection, RNA was purified for the PAT assay, and luciferase activity was measured from cell lysates. As reported previously, the presence of functional let-7 target sites results in specific repression of luciferase expression with very minor effects on mRNA stability (Pillai et al., 2005). The experiment in Fig. 6.3C demonstrates that the let-7 targeted reporter mRNA is selectively deadenylated. [Pg.133]

Parameters of dynamically hot galaxies , i.e. various classes of ellipticals and the bulges of spirals, generally lie close to a Fundamental Plane in the 3-dimensional space of central velocity dispersion, effective surface brightness and effective radius or equivalent parameter combinations (Fig. 11.10). This is explained by a combination of three factors the Virial Theorem, some approximation to... [Pg.356]

The solution conformation of plastocyanin from French bean, spinach, and S. obliquus has now been determined from distance and dihedral angle constraints derived by NMR spectroscopy [37,40]. These two-dimensional NMR studies have indicated a well defined backbone conformation, which is very similar to that of poplar PCu in the crystalline state. However, in the case of S. obliquus there are deletions at positions S7 and 58 which influence the shape in the acidic region and in particular close to residues 59-61. The gap which is created is in effect repaired with consequent tightening of the loop 57-62 as indicated in Fig. 5. One of the pronounced bulges at the remote site of poplar and presumably other higher plant plastocyanins is not therefore present in S. obliquus (or plastocyanin from other green algae) [31, 32], as well as parsley... [Pg.183]
