Correction tables

Minimum thickness requirements are 11/2 times the indentation diagonal measurement, and there should be no visible marking or bulge visible on the side opposite the indentation.The Vickers test is based on a plane surface however, correction tables are available for both convex and concave surfaces (see ASTM E92) (2). 

Several spectroseopie constants derived with and without the Davidson correction (Table 6) show little differences except for ke, tte and tOeXe, the overall agreement with experiment being satisfactory. As for the X state, the Davidson correction tends to reflect experiment sometimes better, e.g. for cOeXe.Be. whereas the discrepancy with respect to experiment is sizeably reduced for Oe-... 

Once the pure mineral powders characterized, 3 mixtures were manually prepared and named ML1, ML2 and ML3. They contain each of the 8 minerals in different proportions reproducing 3 mine tailings falling in the uncertainty zone of the static test used. The 3 synthetic tailings were characterized with the same techniques as for the pure minerals. Cp and Sp weight fractions were evaluated from their chemical element tracers (respectively Cu and Zn) obtained from ICP-AES analysis. Qz, Dol, and Sid samples are considered pure and their percentages in the mixtures are not corrected. Table 1 presents the fraction of each mineral in the three mixtures before and after correction taking into consideration the contamination of Po sample by pyrite and calcite, as previously determined. The corrected mineral proportions are used for calculation of the static test parameters based on... 

However, very recent results obtained in a collaborative study by one of the authors eliminate this anomaly, and correct Table 1 and Fig. lb. Starting with the... 

Because fuel and oil weights vary per standard volume, they should always be handled and sold on a weight basis, not volume basis. If sold on a volume basis, the volume should always be corrected to 60°F (15.5°C) by utilizing API volume reduction tables. These tables are used to standardize all volumes of petroleum products to a 60°F (15.5°C) volume. Standard API volume correction tables for petroleum products are contained in APPENDIX 3. 

Thus x and v transform according to E, and z transforms according to Ax, which are the results stated in the complete form of the mathematically correct table. (Note cos 4n/3 = cos 2tt/3.)... 

Copper. In the presence of sulfur dioxide, copper-protein cloudiness may develop in white wines. Only small amounts of copper (about 0.3 to 0.5 mg/liter) cause cloudiness. Widespread use of stainless steel in modern wineries has reduced copper pickup, but many wineries routinely test their wines for copper. Atomic absorption spectrophotometry is the method of choice (51) although reducing sugars and ethanol interfere, and correction tables must be used (107). To reduce this interference, chelating and extracting with ketone is recommended (108). Lacking this equipment colorimetric procedures can be used, especially with di-ethyldithiocarbamate (3, 4, 6, 9,10, 22,109). Neutron activation analysis has been used for determining copper in musts (110). 

A structure determination of the complex showed the latter to be correct (Table V) (295). The tin atom is six-coordinate with distorted octahedral... 

CORRECTION TABLE FOR TOTAL SOLUBLE SOLIDS DETERMINED BY MEANS OF THE REFRACTOMETER IN SUCROSE SOLUTIONS CONTAINING CITRIC ACID (2)... 

The corrections shown in Table 2.10 are only valid for distilled water. Different liquids will have different coefficients of expansions and therefore will require different corrections. Table 2.11 provides a few representative solutions at different normalities and a factor to correct Table 2.10 for volumetric discrepancies. 

Calibration correction tables for single-pan balances are provided in Table 2.14, which is used in the same manner as the previous example. Like Table 2.12, this table is used when a volumetric flask is Type I, Class A (borosilicate glass). It may... 

Note These tables cover the approximate total solids levels of these products in commerce. If the ash or dextrose equivalent of the sample differs from the product in the table, use the accompanying ash and dextrose equivalent correction table. 

We will treat molecules with vinyl carbons as derivatives of ethylene (H2C=CH2, Section 6.3), whose l3C signal appears at 8 123.3.1 To this base value, we will apply A8 corrections (Table 7.3) for substituents according to their location with respect to the carbon of interest. 

Apply the respective system factors. Studies and experience show that the calculated pump-down time for a vacuum system must be corrected by an appropriate system factor. This factor makes allowance for the normal outgassing of surfaces exposed to atmospheric air. It also provides a basis forjudging whether a system is pumping down normally or whether some problem exists that must be corrected. Table 6.33 lists typical system factors that have proven reliable in many tests. To use the system factor for any pump, apply it this way ta = tS. where ta is actual pump-down time, in min t is computed pump-down time from step 3, in min S is system factor for the type of pump being considered. 

The assumption of equal probabihty is correct. Table 1.13 has 61 members. If you were to determine the probabihty of element number 16 in this table, for example, how would you do it Unless it is known that this element is biased, its probability has to be 24 in 62 = 0.39. 

Experimental data were embodied in tables presenting C Re in terms of Re/Cf) and vice versa. Since the former expression is independent of velocity and the latter is independent of particle diameter, the velocity may be determined for a particle of known diameter and the diameter determined for a known settling velocity. Heywood also presented data for non-spherical particles in the form of correction tables for four values of volume-shape coefficient from microscopic measurement of particle-projected areas. 

Aristotle s elements refer to states, rather than to kinds of matter. The Aristotelian concept of elements was thus very remote from the.modern concept, and the two seem to have in common only a striving to find simplicity in nature. The modern concept of elements as simple forms of matter was first introduced by the English scientist Robert Boyle (1627-1691), in his book The Skeptical Chymist, published in 1662. The first successful application of Boyle s concept was made by the French chemist Antoine Laurent Lavoisier (1743-1794), who gave an essentially correct table of thirty-three elements (including, however, heat and light ) in his book Truite hlementaire de Chimie in 1789. 

In general, the volume received or delivered is calculated from the observed gauge readings. Corrections are made for any free water and sediment as determined by the gauge of the water level in the tank. The resultant volume is then corrected to the equivalent volume at 15.6°C (60°F) by use of the observed average temperature and the appropriate volume correction table (ASTM D-1250). When necessary, a further correction is made for any suspended water and sediment that may be present in materials such as crude petroleum and heavy fuel oils. 

Although no correct table of elements had been organized before that time, our modern Periodic Table would have looked like this in 1869 ...

In trialkyl phosphanes, the magnitude, whereas the Hp coupling constants are significantly larger. Coupling constants in aryl phosphanes are even more difficult to assign correctly. Table 2.6 shows a few representative examples. 

Attention should be directed at all stages to the prevention of packaging errors. Sound procedures must be employed to protect the quality of the product when it is packaged and to ensure that the correct tables are applied to the containers. 

The second set of corrections (Table 4, Part B) is for Y interference on Pb and Th interference on U, as applied to chemical U-Th-Pb monazite ages. The uncorrected U, Pb and Th concentrations yield a U-Th-Pb chemical age of 417 Ma, and the corrected compositions yield chemical U-Th-Pb ages of 392 Ma (Virtual WDS correction) and 389 Ma (empirical corrections from Pyle 2001). The empirical and Virtual WDS correction factors are virtually identical for Y Ly2,3 interference on Pb Mai (0.0031 and 0.0030, respectively), so most of the corrected age estimate difference arises from the difference in Virtual WDS (0.0130) and empirically measured (0.0101) correction factors for Th MPi interference on U Mai.
