Yield analysis change

Z3. PMDA-ODA on MgO. PMDA-ODA peel force data shown in Fig. 7 exhibit a very interesting phenomenon as a function of T H exposure. The peel force is significantly increased as the time in T H is increased. This is somewhat unusual, but apparently repeatable. The exposure to APS has not made much difference in the results, which is understandable from the initial surface analyses after IPA cleaning and APS exposure. The XPS data show no detectable amount of APS on the thus exposed MgO surface. The reasons for the peel force increase as a function of T H exposure are not clear at this time. This is, however, due to increased interfacial strength, and not due to the polyimide mechanical properties (Young s modulus and yield stress) changes. If the latter were the case, then we should see similar effects also in the first two cases, which is not seen. However, more detailed analysis is essential to clarify the exact mechanism and this observation merits further study. [Pg.419]

For example, consider the UK gilt principal strip discussed earlier that matures on June 7, 2021 and on a settlement date of May 30, 2003 is priced to yield 4.435%. Exhibit 4.1 presents Bloomberg s Yield Analysis screen for this security. Let s change (i.e., shock) the note s required yield up and down by 20 basis points and determine what the new prices will be in the numerator of equation (4.1). If the required yield were decreased by 20 basis points from 4.435% to 4.235%, the strip s price would increase to 46.99. Conversely, if the yield increases by 20 basis points, the strip s price would decrease to 43.99. Thus,... [Pg.110]

No allyl complexes of titanium or vanadium have yet been reported. We have prepared allyl-bis(cyclopentadienyl)-titanium [I] by various methods, of which the following is the most convenient one. Red bis(cyclopentadienyl)-titanium dichloride [II] in tetrahydrofuran solution was reduced to the green monochloride by means of zinc powder (1). When the reduction was completed, one equivalent of allylmagnesium chloride was added to the solution, the col r of which changed to violet. The reaction mixture was evaporated in vacuo, and the residue exuacted with pentane. When the violet pentane solution was concentrated to saturation and cooled to -80 , purple crystals of [I] precipitated. After two recrystallizations from pentane pure [I] was obtained in 36%yield. Analysis found 21,8%Ti 70,89%C 7,01%H calc, for (CgHg TifC Hg) 21,86%Ti 71,24%C 6,89%H. Melting point . 118 C (decomp.). Reaction of [I] with octanol gave propene in 80% of the theoretical yield. [Pg.227]

With the exception of the scanning probe microscopies, most surface analysis teclmiques involve scattering of one type or another, as illustrated in figure A1.7.11. A particle is incident onto a surface, and its interaction with the surface either causes a change to the particles energy and/or trajectory, or the interaction induces the emission of a secondary particle(s). The particles that interact with the surface can be electrons, ions, photons or even heat. An analysis of the mass, energy and/or trajectory of the emitted particles, or the dependence of the emitted particle yield on a property of the incident particles, is used to infer infomiation about the surface. Although these probes are indirect, they do provide reliable infomiation about the surface composition and structure. [Pg.304]

Discriminant Sensory Analysis. Discriminant sensory analysis, ie, difference testing, is used to determine if a difference can be detected in the flavor of two or more samples by a panel of subjects. These differences may be quantitative, ie, a magnitude can be assigned to the differences but the nature of the difference is not revealed. These procedures yield much less information about the flavor of a food than descriptive analyses, yet are extremely useful eg, a manufacturer might want to substitute one component of a food product with another safer or less expensive one without changing the flavor in any way. Several formulations can be attempted until one is found with flavor characteristics that caimot be discriminated from the original or standard sample. [Pg.3]

Yoon et al. [600] investigated the influence of the process temperature on the yield of tantalum powder and amount of fine fraction obtained. The reduction was performed using K2TaF7 dissolved in a KC1 - KF melt. The melt temperature varied in the range of 800-980°C. The analysis of the obtained results shows that the yield of the process increases at higher temperatures. In addition, higher temperatures lead to a decrease in the amount of fine fraction of tantalum powder produced. Nevertheless, it was noted that solely changing the process temperature does not ensure an improved yield. [Pg.335]
