Sample coordinator

Adequate pre-shop provision, thorough training, and strict oversight of the shoppers, as described above, were critical to the successful execution of the sample collection phase of the OPMBS. Each shopper received a kit containing sample labels and containers to hold the sampled commodities, ice packs and packaging materials, labels and boxes for use in shipping the collected commodities, written instructions, and forms well before the scheduled date of collection. The sample coordinator monitored sample collection and advised shoppers of actions to take when problems inevitably arose.

Figure 5. Abundance of opal phytoliths as summarized from original petrographic data. Key 0, absent R, rare C, common and A, abundant. Sample coordinates same as in Figure 3. Note essential absence of phytoliths in the Sierra units 1 and 2 (Palenque), and 7 (Xupa orientation).

In the principal components plots presented in this paper, the number plotted corresponds to the sample identification number given in the appendix. If more than one sample has the same locus in the score (Theta s) or loading plots (Beta s), the letter M is plotted. The values for the sample coordinates in the principal components plots can be listed by the SIMCA-3B program. 

The PLS scores are interpreted in the same way as PCA scores since they are the sample coordinates along the model components. The additional feature in PLS is that two different sets of components are considered, summarizing variations in the X space or Y space. PLS loadings express the relatedness of each X and Y variable to the model component. T scores are the coordinates of data points located in the X space that describe the part of structure in X which is most predictive for... 

Fig. 5 Calculated changes in the average rise and roll angle of the separated to the intercalated state transition along the sampling coordinate X. Note that the roll angle increases earlier than the rise as the intercalating drug approaches.

Fig. 6 Potential of mean force (PMF) along the sampling coordinate X leading to intercalation (solid line, X decreases as the drug approaches DNA) and leading to the minor groove-bound state transition (dashed line). The dotted line shows the barrier height for intercalation from the minor groove-bound state.

The umbrella sampling technique [14] allowed the obtaining of our sampling coordinate (X) probability distributions, which then were combined by the... 

To assure the correctness of the SAP implementation, a chemist (often called sample coordinator) coordinates sampling crews in the field and keeps track of the collected samples. 

A complete description of the texture (or preferred orientation) is formulated as a probability for finding a particular crystallite orientation within the sample this is the orientation distribution function (ODF). For an ideally random powder the ODF is the same everywhere (ODF=l) while for a textured sample the ODF will have positive values both less and greater than unity. This ODF can be used to formulate a correction to the Bragg intensities via a fourdimensional surface general axis equation) that depends on both the direction in reciprocal space and the direction in sample coordinates ... 

In a diffraction experiment the crystal reflection coordinates (cj), p) are determined by the reflection index (h) while the sample coordinates (ij/, y) are determined by the orientation of the sample on the diffractometer. This formulation assumes that the probability surface is smooth and can be described by a sum of spherical harmonic terms, kfl and kjf, that depend on h and sample orientation, respectively, to some maximum harmonic order, L (ref. 25). The coefficients Cf" then determine the strength and details of the texture. Notably, only the even order, L = 2n, terms in these harmonic sums affect the intensity of Bragg reflections the odd order terms in the ODF are invisible to diffraction. 

The position of any polymer chain (or a segment of that chain) in an oriented (drawn) sample can be described by a rotational transformation of tensors from a molecular coordinate frame in a typical structural unit (xyz) to a sample coordinate frame (XoYqZo) with the Euler angles (afSy) and (aijSiyi) (Fig. 8.1). 

Fig. 8.1. (a) Orientation of a typical structural unit in the sample coordinate frame XqYoZo where Z is the draw direction of a uniaxially stretched polymer (b) orientation of the sample in the laboratory frame XYZ where Z denotes the direction of Bq and Zq is the sample draw direction.
