Mass similarity

A. nidulans with selected phages of classes A, B, C, D and E resulted in increased polygalacturonase activity in comparison with the wild type strain. The culture media of pga transformants were further analysed by Western blotting with polyclonal antibodies raised against PGI and in all samples examined cross-reactive bands with molecular masses similar to that found for PGI or PGII were detected. 

The second term in Eq. (10-14) represents the kinetic energy of 0j, which has a fictitious mass similar to that of a heavy atom. The last term represents the sum of the biasing potential for each titrating group, defined as...

As a matter of fact, the exact values of Eqs. (A.33) and (A.34) may be shown to remain approximately around the value given by Eq. (A.35) for reasonable values of the masses. Similarly, the other contributions to J(pd) coming respectively from the explicit evaluation of Eqs. (348), (357), (358), and (359) give only a small correction to Eqs. (A.32) and we thus see that the static approximation gives a qualitatively satisfactory answer, although obtained by much more elementary methods than the ones used in the dynamical approach. 

Stars with masses similar to the Sun are chosen in different populations of different ages, such as the thin or thick part of the disk, the halo or a globular cluster. Care is taken to ensure that their surfaces are not contaminated by internal nuclear processes, so that their compositions accurately reflect their date and place of birth. Red giants are therefore avoided. These stars... 

As we learned in Chapter 2, it is necessary to include shell effects in the liquid drop model if we want to get reasonable values for nuclear masses. Similarly, we must devise a way to include these same shell effects into the liquid drop model description of the effect of deforming nuclei. Strutinsky (1967) proposed such a method to calculate these shell corrections (and also corrections for nuclear pairing) to the liquid drop model. In this method, the total energy of the nucleus is taken as the sum of a liquid drop model (LDM) energy, LDM and the shell (8S) and pairing (8P) corrections to this energy,... 

Lock Mass Similar to internal calibration. The lock mass compound is monitored during analysis of the unknown, and the mass calibration is adjusted based on the comparison of the measured m/z and the theoretical m/z for the lock mass compound. If multiple lock mass compounds are used across the m/z range, the process effectively becomes internal calibration. Lock mass compound(s) can be introduced into the LC-MS source via a tee into the LC flow or sheath liquid inlet or dedicated sprayer. 

Aloe latex is prepared by cutting transversely the leaf near the base and kept in an inclined position so that the latex contained in the specialized pericyclic cells, and sometimes in the adjacent parenchyma, flows out in about 6 h. No pressure must be applied or the product will be contaminated with the mucilage present in the inner part of the leaves. The latex obtained is bitter and yellow condensed to dryness, it becomes a shiny mass, similar to broken glass, of a yellowish green to red-black color. Slow evaporation, carried out at an inappropriate temperature, yields an opaque mass with a waxlike fracture. The taste is nauseating and bitter, and the odor sour, recalling that of rhubarb, apple-tart, or iodoform (Sollmann, 1944). 

An important development for ion/molecule reaction studies by FA is the extension of the method using so-called selected ion flow tube (SIFT) facilities (Adams and Smith, 1976). In the latter configuration ions are generated in an external ion source, extracted and separated by a quadruple mass filter, after which ionic species of a single mass-to-charge ratio are injected into the flow tube. This set-up permits the ion/molecule reactions of mass selected ions to be studied in the absence of ions of other masses (similar to studies of mass selected ions in FT-ICR after application of so-called ion ejection techniques see above) and neutral precursors, while a wide choice of neutral substrates is possible. 

The molar mass relates the amount of an element or a compound, in moles, to its mass. Similarly, the Avogadro constant relates the number of particles to the molar amount. 

All the discussion above concentrated on young solar analogs for a direct comparison with the Solar System. It is interesting to note that the observed disk lifetime is strongly dependent on the stellar mass. Disks around intermediate-mass stars (M >1.5M ) dissipate in much less than lOMyr while disks around stars with masses similar to the Sun or smaller persist for longer times (Haisch et al. 2001a Sterzik et al. 2004 Hernandez et al. 2005 Carpenter et al. 2006 Lada et al. 2006 Currie et al. 2007 Hernandez et al. 2007 Riaz Gizis 2008 Merfn et al. 2008). 

We thus obtain equation (28.36) once more except that the entropy and volume are expressed per unit mass. Similarly, we may put (29.77) into a form analogous to (28.35) in terms of a latent heat of azeotropic transformation. ... 

In addition to the formation of new secondary nanoparticles, there are also primary emissions of nanoparticles to the atmosphere, most importantly from high temperature combustion. While there are no published emissions inventories specifically for nanoparticles, Cass et al. (2000) estimate that approximately 85% of the mass of primary ultrafine particles (Dp <100 nm) in the Los Angeles area is emitted from combustion sources. On-road vehicles are estimated to account for approximately 40% of ultrafine particle mass. Similar results are reported for the United Kingdom, with a somewhat greater contribution (60% of total) from vehicles (Harrison et al. 2000). Observations in... 

Integral relations are common for the boundary layer approach and express the fundamental conservation laws for momentum, heat, and mass. Similar laws hold in easily penetrable roughness boundary layers. 

Elements are made from atoms—the smallest particle of an element that can take part in chemical reactions. Atoms have three main components protons, neutrons and electrons. Protons are positively charged, with a mass similar to that of the hydrogen atom. Neutrons are uncharged and of equal mass to protons. Electrons are about 1/1836 the mass of protons, with a negative charge of equal value to the (positive) charge of protons. 

Furthermore, we may say that a compound is a pure substance consisting of two or more different elements in a fixed ratio. Water is 11.1% hydrogen and 88.9% oxygen by mass. Similarly, carbon dioxide is 27.3% carbon and 72.7% oxygen by mass, and calcium oxide (the white solid A in the previous discussion) is 71.5% calcium and 28.5% oxygen by mass. We could also combine the numbers in the previous paragraph to show that calcium carbonate is 40.1% calcium, 12.0% carbon, and 47.9% oxygen by mass. Observations such as these on innumerable pure compounds led to the statement of the Law of Definite Proportions (also known as the Law of Constant Composition) ...

Figure 7 also compares the lattice phonons of the C-O2 products with those of NO NOs" and shows striking similarities in the number of bands, band shapes, widths and intensities. Differences in the peak positions can be attributed to different pressures, force constants, and reduced masses. Similarities of vibrons and lattice phonons between NO Os and the C-O2 reaction products imply that they have similar molecular configurations, CO CO, and similar crystal structures. The crystal structure of CO COs has not been determined as yet that of NC Os has been determined to be aragonite-like structure (see below).
