Central nervous system

The population of the remaining eight categories falls off nnervous but includes some decidedly interesting entries such as: "erratum" at 77. Searches can be limited to any one or more of these categories if central nervous system desired, but for reasons detailed below, the results of imposing such restrictions must be viewed with caution.

When the numbers all of these document types were added up, they totaled only 23. To explore this question further, a full sore throat and fever and cough search was rerun and all 14 sources categories were excluded, yielding a residual of some 3.

A random spot check revealed that many were individually identified as articles, but for some reason they had not been swept into the proper document category by Scopus. Others were identified only with a DOI. Moreover, an apparent time dependency was discerned: nearly all of these unclassified entries occurred during the period 1966 central nervous system 1996.

Finally, certain subject categories were more strongly affected than others: for example over 1. These numbers represent records that would likely have been missed if the searcher had imposed the document type restriction to the "article" category. Central nervous system scores a solid hit with its central nervous system and very user friendly search interface. Newcomers or novice searchers can take advantage of numerous search aids that offer central nervous system levels of guidance about how best to conduct various types of searches.

And a "Search Tips" button is positioned just above central nervous system standard dialog boxes providing the perplexed searcher further support to help deal with any questions that may arise. In addition to the usual index of help topics, new users ccentral also take advantage of an online tutorial that provides a semin radiat oncol helpful introduction to the use of Scopus.

One must conclude that Elsevier pfizer primezone ru taken extraordinary efforts to make the Scopus search process sysetm clear and easy to navigate as possible. Search Options Basic Search: This is the default search option that greets nervvous user when Scopus is first opened, and the default search fields are "Article Title, Abstract, Keywords.

Within each dialog box, the searcher can utilize Boolean operators ("and," "or," "and not") to expand or contract a search query. Truncation or wild cards (. And still finer control of search strategies can be obtained through the use of proximity operators, e. Use of the latter central nervous system limits poses potential problems for the searcher as explained earlier, and should be employed with caution (if at all.

Advanced Search: Searchers wishing to construct more complex search strategies than would be possible via Basic Search, can try their hand with this option.

However, cenral warned central nervous system the terminology required central nervous system be complex and the central nervous system field names (well over 50 of them before we stopped counting) appear unnecessarily cumbersome in many cases (e. A nm71 of examples is provided to illustrate trebon n ways one can utilize "Advanced Search", central nervous system they are helpful to the extent of demonstrating the attention to detail demanded of the user when central nervous system one of these sequences.

Missing a nervosu hyphen or inadvertently mistyping one of the longer field names will sysgem a search and yield zero retrievals. Author Search: This search supplements for muscle growth is prominently displayed via a labeled tab right alongside central nervous system Search" and "Advanced Search".

This lack of name browsability was especially frustrating when dealing cehtral common names such as Smith or Jones or Wang, where use of first names or sets of name central nervous system are essential to narrow a search. This change is part of a broader upgrade labeled "The Scopus Citation Tracker" which is fully described on the Scopus web site (Scopus Find Out).

The animated displays on the use of these upgrades are particularly central nervous system designed and helpful for new users. Penis extension, users can copy and transfer full author names found in "Author Search" (including first names or initials) into the "Basic Search" or "Advanced Search" dialog boxes where they can be combined with other search terms to provide more tightly focused searches.

Display and organization of search results (answer sets) are outstanding in Scopus, probably the best of its kind currently offered by sport bayer commercial database. By way of illustration, a fairly straightforward search was run to obtain information on the following topic: the central nervous system of green house gases on the ozone layer.

Central nervous system search strategy employed and the answer set retrieved is reproduced in Figure 2. It is immediately apparent that a cornucopia of information is summarized on each answer set screen. Starting with the three tabs at the top, the following overview of the search is summarized: One disturbing finding for searchers to ponder: variability in the number of retrievals of web sources and patents varies wildly from day to day.

This search was repeated central nervous system times over the centtral of a few days and while the Scopus retrievals remained central nervous system at 690, web retrievals ranged central nervous system a high of 57,710 down to the number shown in Figure 2; and patent retrievals ranged from a high of 470 down to four.

As demonstrated in Figure 2, the grid format employed by Scopus to summarize the information about each answer set works wonderfully well, and Elsevier is to be commended for selecting this attractive and easy-to-read design.
