Square numbers

Because the velocity is implicitly defined [17] when electric and magnetic fields are used in the geometry shown in figure 5, the rate of energy loss is independent of the mass of the particle and is just proportional to the atomic number squared ... 

A consequence of the screening of the nucleus by the electrons is that the cross section for low energy ion scattering varies less steeply with the atomic number than in RBS, where the intensity depends on the atomic number squared. Another difference with RBS is that the scattering intensity is not only determined by the cross section, but also by the probability that an ion is neutralized. 

In a rheomety experiment the two plates or cylinders are moved back and forth relative to one another in an oscillating fashion. The elastic storage modulus (G - The contribution of elastic, i.e. solid-like behaviour to the complex dynamic modulus) and elastic loss modulus (G" - The contribution of viscous, i.e. liquid-like behaviour to the complex modulus) which have units of Pascals are measured as a function of applied stress or oscillation frequency. For purely elastic materials the stress and strain are in phase and hence there is an immediate stress response to the applied strain. In contrast, for purely viscous materials, the strain follows stress by a 90 degree phase lag. For viscoelastic materials the behaviour is somewhere in between and the strain lag is not zero but less than 90 degrees. The complex dynamic modulus ( ) is used to describe the stress-strain relationship (equation 14.1 i is the imaginary number square root of-1). 

Figure 10.5. The 1 pm versus 2 pm pyroxene spectral determinative curve widely used to identify compositions and structure-types of pyroxenes on planetary surfaces (from Adams, 1974). Circles refer to room-temperature data. Numbered squares (orthopyroxene En86Fs14) and triangles (clinopyroxene Wo42En51Fs7) represent spectral data obtained at the temperatures (1) 80 K (2) 173 K (3) 273 K (4) 373 K and (5) 448 K (modified from Singer Roush, 1985).

We can easily understand the essential, drive-induced, behavioral consequences by observing the movement of rats in an open field with numbered squares in which activity is measured by the number of squares crossed in a 30-min period and by the total area covered during this period. Due to the innate orienting-searching reflex activity, a naive rat put in this open field looks searchingly around for a short while and then stops moving. 

An even better reason exists to expect that the nucleophilicity of a transition metal complex would depend strongly on its ease of oxidation. Reaction with an alkyl halide, according to either reaction 1 or 2, is an example of oxidative addition. The oxidation state of the metal increases by two units. Taking a definite example, we find that the change is more than a formal one. The reactant is a typical d10 complex, whereas the product is a definite d8 complex. The product has the right coordination number, square-planar structure, and visible-UV spectra found for similar Pt(II) complexes.

A number that caimot be expressed as a ratio n/m is called irrational. (Irrational here does not mean insane but rather not expressible as a ratio). The most famous irrational is V2, which did, however, drive the followers of Pythagoras somewhat insane. To prove the irrationality of V2, assume, to the contrary, that it is rational. This implies that V2 = n/m, where n and m are relatively prime. In particular, n and m cannot both be even numbers. Squaring, we obtain... 

Lay out the test strip on the bench. Using a clean pipet tip each time, remove a l-pL aliquot from each collected fraction and spot it into the center of the correspondingly numbered square on the test strip. 

Only in DCCD-treated samples, proton uptake from the medium exhibited a dependence on the flash number (squares in Fig.2), namely, very little decrease on the first flash (no proton release by water oxidation in control samples) and maximum decrease in the third flash (when proton release was maximum). This supported the notion that the non-released protons due to water oxidation were indeed transferred directly to the reduced bound quinone. 

As was discovered, the spread in numerical values for parameter /from 0.5 to 0.7 was less satisfactory in the selection of all parameters for optimization on the experimental series. This can be explained by the fact that the most important section of the kinetic curve for estimation of parameter /, namely the slow and long section, is characterized by low values dP/At and forms only a small share of the function of number squared of calculated deviations from experimental ones. Fixing the parameter y showed that the minimal standard error in the estimation of tvo and /3 is observed at the value /=0.6. Thus, all experimental curves dP/dt =f[t) were compared with equation (7.23) at fixed value y=0.6 with optimization only on two parameters, namely wo and jS. Examples of comparison of values calculated using equation (7.23) (lines) in accordance with experimentally determined kinetic curves (points) are presented in Figures 7.10-7.14. Note that in all cases satisfactory correspondence is found between experimental kinetic curves and kinetic curves calculated using equation (7.23). 

Immunofluorescence staining and autoradiography are described in detail elsewhere in this book. Grow the cells on slides with numbered squares. This allows identification of the injected cells at any time. 

The bottles were placed in arrays on a remotely operated split-table device, using neutron multiplication techniques to estimate the number of bottles for criticality. Extrapolations were also made on spacing to determine the critical spacing for fixed-number square arrays of the bottles. Arrays were single tier, except in one experiment where a double-tier array was used.

Figure 19 The active side chains are shown in (a). How the side chains are divided into biconnected components is illustrated in (b). Each side chain is numbered with a DEN (circle) and a low number (square next to corresponding residue). A difference between the DEN and the low number indicates the existence of an articulation point for the group of active sidechains. This image was adapted from Canutescu et al. ...

Using a sterile toothpick, pick one white colony and suspend cells in the water in the 96-well plate. (A quick dip in the water will do.) Subsequently, streak the toothpick lightly within a square of the number-labeled plate. The numbered square must correspond with the numbered well of the 96-well plate. 

The expressions on the right-hand sides of (7.1.13) and (7.1.14) are often confusing at first because of their apparent dimensional inconsistency. The first term has the dimension of number while the second (as also the left-hand side) has that of number square. This inconsistency can be reconciled, as it is the consequence of constraining the number of particles in any inifinitesimal interval to be at most 1. The expressions generalized to include more particles, appearing subsequently, are free from such apparent inconsistency.
