Cross search

StatlRef StatlRef [56] combines more than 30 medical and drug information textbooks from several publishers and allows both individual and cross searching. The texts are commercially available in a variety of electronic combinations. 

Prinke, Rafal T. Early symbolism of Rosy Cross searching for link with tradition. Hermetic J, no. 25 (Autumn 1984) 11-15. 

To ensure coverage of a broad spectrum of journals containing both original and review articles, bibliography databases, such as CAB abstracts, BIDS ISI and Embase, Medline and Current Contents Agriculture and Food Citation index, were searched. Terms used for all database searches were kept simple to limit the risk of missing any original publications (Table 4.5). Initially, each flavonoid subclass was entered and then cross-searched with the... 

Some of the special advantages of STN include advanced chemical structure searching, easy searching and cross-searching of complementary data-... 

No claim is made for the inclusiveness of this chapter as far as specific species are concerned. Rather, what is included is meant to be indicative of the types of carbohydrates found extraneous to the primary and secondary cell walls, and the orders and families in which particular carbohydrates are found. Examples given here are from the more recent literature for the most part. Although the more recent investigations used better methods of analysis, it should be recognized that contemporary methods of carbohydrate analysis have yet to be applied to examination of the extractable carbohydrates of woody tissues. To confirm the presence of extractable carbohydrates in woody tissue, it is recommended that a cross search by compound (number and/or name) and genus be conducted and that the papers uncovered in this search be scrutinized for occurrence in a specific tissue. 

Based on that first criterion, the DARC Communication Modules have been developed in such a way that they provide DARC-SMS with an easy and quick access to the DBMS data, but also easy and quick access to the chemical structures stored in DARC-SMS, from the DBMS, as well as easy cross search, starting either from DARC-SMS or from the DBMS. 

The second criterion considered was related to access to the DBMS search capabilities. Since DBMSs have proven their ability to fulfill the needs of researchers in the chemical and pharmaceutical industries as well as in other fields of activity, it appeared to be essential that for cross searches, the DARC Communication Modules give full access to a DBMS session, or limited access depending on the needs or the allowance of the users.

Cross Search of Chemical Structures and DBMS Data the DISPLAY/SELECT module. The purpose of the DISPLAY/SELECT module is to allow cross searching between DARC-SMS and the DBMS, starting either from DARC-SMS or from the DBMS and combining both types of cross searches (see Figure 11).

Besides the usual cross search, which allows the user to refine or expand a substructure search through a data search and again to refine the results of the combined search through a second substructure search, the DISPLAY/SELECT module offers an offspring search capability. Indeed the results of the initial substructure search within DARC-SMS are kept even after a data search in the DBMS, so that the researcher can always refine the results of his or her initial (sub)structure search through various data searched in the DBMS. 

The phase-change nale, also known as the Ben phase [101], the geometric phase effect [102,103] or the molecular Aharonov-Bohm effect [104-106], was used by several authors to verify that two near-by surfaces actually cross, and are not repelled apart. This point is of particular relevance for states of the same symmetry. The total electronic wave function and the total nuclear wave function of both the upper and the lower states change their phases upon being bansported in a closed loop around a point of conical intersection. Any one of them may be used in the search for degeneracies. 

Worth and Cederbaum [100], propose to facilitate the search for finding a conical intersection if the two states have different symmetiies If they cross along a totally symmetric nuclear coordinate, then the crossing point is a conical intersection. Even this simplifying criterion leaves open a large number of possibilities in any real system. Therefore, Worth and Cederbaum base their search on large scale nuclear motions that have been identified experimentally to be important in the evolution of the system after photoexcitation. 

Secondary sources of patent information, Advances in patent documentation. Types of patent information searches. On-line database searching methods. Cross-file and multifile techniques. 

Searching of one or more on-line databases is a technique increasingly used ia novelty studies. The use of such databases enables the searcher to combine indexing parameters, including national and international classifications natural language words ia the full text of patents, ia their claims, or ia abstracts suppHed by iaventor and by professional documentation services and indexing systems of various sorts. Because the various patent databases have strengths and weaknesses that complement each other, the use of multiple databases is thus pmdent, and is faciUtated by multifile and cross-file techniques provided by the various on-line hosts. 

EDOG. EDOC, available on just the Questel system, provides in most instances less complete patent family information than either WPI or INPADOC, but it is unique in including Japanese C-level documents and also some AustraUan data not available in the other two databases. It is possible on occasion to find family information from before 1970 in this database, though such data are not provided systematically. The abiUty to search by the EPO-modified version of IPC is unique. Its value is tempered by the fact that output does not even include tides, much less abstracts of patents. That output can, however, be transferred by cross-file search protocols to more detailed files, such as WPI. 

Hand in hand with this research on finding a suitable carboxyUc acid chemical for cross-linker has been the search for an economical catalyst system. The catalyst found to be most effective for the esterification reaction was sodium hypophosphite (NaH2P02). This material was also costiy and out of range for the textile industry. Because weak bases function as catalyst, a range of bases has been explored, including the sodium salts of acids such as malic acid. 

Other 2,3-Diphosphoglycerate Pocket Cross-Linkers. The reactivity of the valine NAl(l)a and lysine EF6(82)p residues in the 2,3-DPG pocket shown by NFPLP and (bis-PL)P4 has stimulated the search for other reagents that react similarly but have potential for greater efficiency and ease of scaleup. The systematic study of four different dicarboxyhc acid derivatives, cross-linked in both oxygenated and deoxygenated conditions, has been reported (92). Each of these derivatives presents problems in purification, and proof of the sites of reaction is tedious. 

A computer search of volumes 70-95 of Chemical Abstracts using the keyword Pyrazine resulted in more than 2600 references, and, after removal of fused pyrazine systems and cross-referencing the remaining references, this number increased to approximately 7000 in total. When the benzopyrazines quinoxaline and phenazine were added the number of references was in excess of 10 000, all of which might be considered to be relevant to a chapter devoted to pyrazines and their benzo analogues.
