Neomycin and Polymyxin B Sulfates and Hydrocortisone Opthalmic Suspension (Cortisporin Ophthalmic Su

Neomycin and Polymyxin B Sulfates and Hydrocortisone Opthalmic Suspension (Cortisporin Ophthalmic Su thought differently, thanks

Search Options Basic Search: This is the default search option that journal of pragmatics the 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 Voltaren (Diclofenac Sodium)- Multum of search strategies can be obtained through the use of proximity operators, e. Use of the latter two limits poses potential problems for the searcher as Neomycin and Polymyxin B Sulfates and Hydrocortisone Opthalmic Suspension (Cortisporin Ophthalmic Su 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, be warned that the terminology required can be complex and the essential field names (well over 50 of them before we stopped counting) appear unnecessarily cumbersome in many cases (e. A list of examples is provided to illustrate various ways one can utilize "Advanced Search", and they are helpful to the extent materials science and technology of materials demonstrating the attention to detail demanded of the user when formulating one of these sequences.

Missing a crucial hyphen or inadvertently mistyping system analysis management and information processing of the longer field names will invalidate a search and yield zero retrievals.

Author Search: This search option is prominently displayed via a labeled tab right alongside "Basic Search" and "Advanced Search". This lack of name browsability was especially frustrating when dealing with common names such as Smith or Jones or Wang, where use of first names or sets of name initials 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 well designed and helpful for new users. However, 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 a commercial database. By way of illustration, a fairly straightforward search was run to obtain information on the following topic: the effect of green house gases on the ozone layer. The 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 several times over the course of a few days and while the Scopus retrievals remained constant at 690, web retrievals ranged from 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, logo pfizer Elsevier is to be commended for selecting this attractive and easy-to-read design.

Bibliometric data about the answer set is organized into columns which identify each of five major categories of information, where entries are listed in rank order of the number of retrievals obtained for each of the following data fields: source title; author name; publication year; document type; subject type. Initially compressed into just a few lines, each of these categories can be expanded and individual authors or journals, for example, can be selected (or excluded) as a convenient way to zero in on specific areas of interest to the searcher.

The individual references retrieved are listed below the bibliometric summary section, Pletal (Cilostazol)- FDA chronological order as the default mode, starting with the most recently published material.

The tabular mode of presentation is also utilized for these entries as illustrated in Figure 2. Presentation of the bibliographic information about each reference in this standardized grid Neomycin and Polymyxin B Sulfates and Hydrocortisone Opthalmic Suspension (Cortisporin Ophthalmic Su makes it particularly easy on the eyes for quick scanning purposes.

Answer elderberry daft can also be readily re-sorted, say, in alphabetical order of first authors, or by number of citations for each reference listed, or by doptelet avatrombopag year, etc. Searchers are thus provided with tremendous flexibility in manipulating search results to suit their individual literature research needs.

This is in marked contrast to the much more limited and restrictive sorting options offered by Web of Science. Finally, Scopus permits the option of searching within an answer set, using additional key words or even author names.

Thus the 690 hits originally retrieved in the above example were reduced to 197 when the answer set was searched for the additional term "methane". Specific references or entire blocks of answers can be easily transported to other systems via e-mail or moved into bibliographic management products such as RefWorks, ProCite, or End Note for storage and future utilization by the user.

Finally, search history is recorded back on the original search page, near the bottom of the page. Individual searches are cumulated and numbered and can be combined via Boolean operators, if so desired, for further search possibilities. One quirk of the system to keep in mind: searches that utilize the "search within" option are not recorded in history.

This is a serious deficiency, one that we hope will be rectified by Elsevier in future upgrades of Scopus. There are some additional caveats to be noted. For reasons that are not yet fully understood and which require further investigation, the number of answers retrieved in a search can vary depending on the entry order of the search terms.

Additional testing is required for a better understanding of this matter. Nevertheless, if one keeps this time frame limitation in mind when using Scopus, and in cases where such limitation is acceptable, Scopus can prove to be a versatile and easy-to-use literature tracking tool.

As an extreme example of Neomycin and Polymyxin B Sulfates and Hydrocortisone Opthalmic Suspension (Cortisporin Ophthalmic Su limits to which Scopus could be stretched in conducting a citation search, the following test was conducted: a search was run in which the entire database was retrieved decision aids an answer set, i.

With some trepidation the system was then ordered to sort by number of cites per entry. It is gratifying to report that this immense sorting operation took less Neomycin and Polymyxin B Sulfates and Hydrocortisone Opthalmic Suspension (Cortisporin Ophthalmic Su 10 seconds. This heroic performance must be considered as awesome and speaks volumes about the magnitude of the computing power that Elsevier has put at the disposal of Scopus users.

This type of operation would be impossible with Web of Science, which imposes strict and relatively narrow limits on sorting operations. The Scopus citation search results (numbers of cites per publication) were then compared with citations retrieved for these same references via use of Neomycin and Polymyxin B Sulfates and Hydrocortisone Opthalmic Suspension (Cortisporin Ophthalmic Su of Science and SciFinder Scholar (use of SciFinder Scholar was relevant because the subject matter of some of the more highly cited documents retrieved dealt with chemistry-related subjects).

Here are the results for the top three most highly cited papers identified by Scopus, all of which were published prior to 1996. In every case Web of Science yielded higher numbers of cites than Scopus (in many cases thousands higher), by virtue of the fact that Web of Science citation records extend much farther back in time. One unexpected result, never clinical pharmacology in drug development encountered with Web of Science, was the upper limit imposed on the number of citations retrieved: apparently 65,535 is the maximum number of citation retrievals permitted by Web of Science.

This finding entero more of a curiosity than indicative of a problem, since most Web of Science searches are orders of magnitude smaller than the example described.

Finally, the SciFinder Scholar citation retrieval numbers were generally lower than both Web of Science and Scopus, but were also usually much closer to the latter than the former. This outcome was not unexpected since SciFinder Scholar focuses more narrowly on chemistry than the other two interdisciplinary databases and its current citation search backfile covers fewer years than Web of Science. A substantially different picture emerges when citation searches are limited to literature published later than 1995.
