If these places stiU do not yield experts or professionals whom you can interview, you can always check your local, national, or even an international phone book to look up any societies, museums, cultural institutions, and perhaps, even private phone numbers of potential primary source individuals. Even if a living family member of President John E Kennedy is not available for information, perhaps a famous biographer or professor would be willing to speak about the topic. There may also be a special historical association or website devoted chiefly to his presidency. 

The potential primary (traceable) method starting from the physical constants and a number of experimentally derived parameters is not able to provide accurate results. 

The purity value of this salt is assigned by a coulo-metric method, which is one of the potentially primary methods for amount of substance determination, according to the CCQM. The principle of this method is as follows given an analyte dissolved in a solution, both the solution and the analyte contained in an electrochemical cell, the amount of electrical charge required to perform a chemical reaction in which the analyte of interest can be converted in another compound, is directly proportional to the amount of substance of this analyte. 

In a theoretical search for phosphavinyl cations, the reactivity of protonated P-alkynes toward P-alkynes has been investigated. Among others, monohydro-1 A3,3A3-diphosphetes have been identified as the potential primary products <20040M3701>. According to density functional theory (DFT) calculations, unsubstituted 1,2-C P is destabilized... 

Levulinic Acid. Dehydration of glucose or other monomeric and polymeric C6 sugars leads to the direct formation of levulinic acid (LA) as a potential primary building block for the biorefinery, and several reviews have described its potential commercial utility 477,478 The preparation of levulinic acid is not difficult, although the mechanism of its formation from carbohydrates is complex, and offers several alternative decomposition pathways (equation 3).479... 

Byproducts of the forest products industry are potentially primary sources of natural resource-based adhesives. Because this industry is both a producer of huge tonnages of residues and a major consumer of adhesives, this book focuses on adhesives from renewable resources derived from trees. Composites made from wood will remain the primary materials used for the construction of homes and their furnishings for the foreseeable future. 

Prior to the elucidation of the structure of the gypsy moth natural attractant, we tested about 2000 synthetics against this insect. Both the isolation and synthesis approaches were being explored. Several attractive compounds were turned up (69). Not so surprisingly, the attractive structures were later found to be similar to the natural attractant, in that they were 16-carbon-atom straight-chain compounds with a primary alcohol group, or at least a potential primary alcohol (epoxy) group. 

Figure 5.6. Overview of the Gridding and Partitioning (GaP) procedure as applied to monomers, exemplified using phenylalanine as a potential primary amine. This molecule thus contains two pharmacophoric groups (the aromatic ring and the carboxylic acid). During the conformational analysis the locations of these pharmacophoric groups are tracked within a regular grid. See color insert. [Reproduced from A. R. Leach and M. M. Hann, Drug Discovery Today, 5, 326-336 (2000),...

With the availability of new non-steroidal agents as reference compounds, the development of new in vitro assays as potential primary screens has been much facilitated. According to Mizushima 4 the thermal denaturation of protein can be inhibited by a number of antiinflammatory compounds with an order of activity roughly in agreement with their in vivo potency. As a simple model to study the stabilization of lysosomal membrauie, Brown J has described a new... 

From the data obtained, the authors postulated that there were three potential primary photolytic reactions for PET [13 ... 

The fact that natural sources of the strictly anaerobic beer spoilers are largely unknown complicates the prevention of contaminations. Potential primary sources include plant... 

Scheme 6.18b. A depiction of a potential primary carbocation lying on the path from the reactants hydrogen bromide (HBr) and 2-methylpropene [isobutylene, (CH3)2C=CH2] to l-bromo-2-methylpropane [isobutylbromide, (CH3)2CHCH2Br].The latter is not found in the reaction.

Percutaneous thermal ablation therapies have been receiving increasing attention as a potential primary treatment for focal HCC and fiver metastases. Possible advantages of ablative therapies as compared to surgical resection include a lower morbidity and mortality... 

Factors affecting the extent of potential (primary) mycotoxin contamination of agricultural crops under field conditions in the preharvest period are summarised as follows ... 

In this context, it is understandable that the complex situation of a wide variety of potential primary tumours, unpredictable sites of metastases, and the patient s individual situation with/without debilitation complicates the set-up of guidelines for the diagnostic work-up in lesion patients. To make diagnostics most efficient, the initial lesion stage at presentation, prior imaging studies, potential previous treatments, the timing of previous treatments, and the overall clinical situation of the individual patient needs to be incorporated.
