BIOSIS Previews 简介

Biological Abstracts/RRM (Reports, Reviews & Meetings) BIOSIS Previews Biological Abstracts (生物学文摘) Biological Abstracts/RRM (Reports, Reviews & Meetings) BIOSIS Previews BIOSIS Previews，结合 Biological Abstracts 和 Biological Abstracts/RRM (Reports, Reviews, Meetings) 这两个数据库的内容，而成为一个单一的数据库，因此BIOSIS Previews 为兼具深度和广度的生命科学暨生物医学数据库。

BIOSIS Previews BIOSIS数据库内容，不但广泛收录来自全世界上千万笔的文献数据，并且以有系统，方便使用的方式呈现给使用者。使用者只需要具备基本的专业知识和简单的查询技巧，就可以在复杂而大量的数据库中，迅速确实的找到完整的相关信息。 BIOSIS Previews, which combines the well established printed references Biological Abstracts and Biological Abstracts/RRM (Reports, Reviews and Meetings) into a single electronic database, is renowned for its quality, and in depth coverage of the world’s b???The strengths and benefits to the user come from unparalleled indexing, which will be explained in this course.

Literature Sources Journals Books Patents Review Articles BIOSIS Previews的独特之处在于，其整合会议记录文献和专利内容，以及学术期刊论文于单一的数据库。也就是说，当使用者在做检索时，可以同时在这许多不同的文献型态中找到相关数据。 Journals Books Patents Review Articles BIOSIS Previews is unique in integrating conference and meeting literature with patents and journals into a single database. This means that searches will automatically retrieve valuable information from these harder to find items. Later in the course we will show that it is also possible to restrict your search to a particular literature type (review, patent, meeting journal ar??? Conferences and meetings

BIOSIS Previews Coverage Journals－ 期刊收录的学术性研究论文等。 Books－ 针对主题的深度讨论和完整研究结果可在 book literature 中找到 Patents－ BIOSIS Previews 收录的专利法案，多与药物，基因工程技术，食品技术等生化科技产品有关，使研究者了解如何让生命科学研究发挥具体的经济效益。 In order to be included in BIOSIS Previews, the item must be published, research and deal with life science topics. This provides for a wide range of literature types and broad subject coverage. Journals provide research articles, reviews etc. while more in-depth discussions can often be found in the book literature. Meetings are a vital and often difficult to locate source of up to date information, with many new findings being first presented at conferences. Coverage of meetings in experimental medicine & clinical research is largely absent from Medline and Embase. T???Patents are becoming increasingly important as all aspects of life sciences become available for patent. This is a vital area as most products here are high value, costly to develop and potentially easy to imitate.

BIOSIS 检索特色

BIOSIS Specialized Indexing BIOSIS Previews的主要宗旨是让研究者取得与生命科学相关的信息。如果您想在某一本书里找寻与特定主题有关的部份，您会翻到这本书最末几页的 “索引”(Index)部份，以得知在书本的第几页可以找到这个特定主题。然而，学术期刊论文和其它文献数据并没有提供像书本一样的 “索引” 部份以供读者查阅，因此BIOSIS根据生命科学领域的内容，建立了一套独特的indexing system。

BIOSIS Specialized Indexing . 系统化字段 BIOSIS DB 检索数量的扩增 检索质量的提升

BIOSIS Specialized Indexing BIOSIS 发展出全新的独有标引方法 (indexing methodology)，称为关连性标引 (relational indexing) 其特色在于能够处理每一个检索字词和控制字汇之间的关连性。这个加值化的索引系统使研究者能快速而正确的找到数据，同时也为信息科技专业人员提供进一步的检索设计。

Specialized Indexing for better retrieval BIOSIS 所独有的编制索引方式, 提供从 事生命科学研究专业人员一个极佳的数 据库检索途径 BIOSIS Specialized indexing 提供不同研究 主题一个统一的检索架构, 使用者可以透 过这个架构获取兼具质与量的资料 BIOSIS employs a team of trained graduate life scientists to index the literature, ensuring accurate representation of the biological content The value added indexing ensures that information can be located quickly and accurately by novices as well as providing advanced search features for the information professional Cross file searching is facilitated by adding additional terms common to other databases: CAS Registry Numbers can be used to locate chemical substances and compounds in a number of databases, including the CAS Chemical Registry database. MeSH disease terms can be searched in MedLine

BIOSIS Searching Fields example 在 BIOSIS Previews 中, 提供多种不同检索字段, 以方便使用者利用 Author .AU. Major Concept .MC. Chemical/ Biochemical .CB. Methods & Equipment .ME. Disease .DS. Organisms .OR. Geopolitical Locations .GE. Meeting Information .MF. CAS Registry Number .RN. Patent Number .PN.

Sample Limit searches to specific fields Turkey (不限制字段) 759 hits Turkey (Geopolitical Location) 399 hits Turkey (Organism) 245 hits

BIOSIS Specialized indexing CA Registry Numbers and MEDLINE MeSH disease terms make searches more effective 为了能达到跨数据库字段检索，BIOSIS也采纳了其它数据库的标引方式，使之具有和其它数据库共有的检索字段。

BIOSIS Value added indexing Controlled & Natural language keywords 控制词汇与自然语言 BIOSIS 在Authority File中加入大量的自然语言 (natural language) 做为控制字汇(controlled vocabulary)，而不再只以编码(codes) 做为专有名词的控制查询。并且研究人员不需记忆大量专有名词，即可做检索的动作 BIOSIS: Indexing is based on natural language/free text with the ability to focus searches using broader controlled terminology and searching terms in context As well as controlled lists of terms in the Authority file, there are broad subject codes and organism group codes MedLine: The extensive hierarchical Thesaurus of MeSH (Medical Subject Headings) terms covers the entire subject scope of the database and can be modified to focus the search using subheadings and check tags EMBASE: EMBASE utilizes and extensive hierarchical subject thesaurus and has additional specialist indexing for drug related material

AUTHOR: Yusoff,-Fatimah-M.-{a}; Matias,-Hazel-B.; Khalid,-Zarina-A.; Phang,-Siew-Moi CORPORATE SOURCE : {a} Department of Biology, Faculty of Science and Environmental Studies, Universiti Putra Malaysia, 43400 UPM, Serdang, Selangor D.E., Malaysia (Federation of) SOURCE: AQUACULTURE 201(3-4), 1 October, 2001: 263-270. ISSN: 0044-8486 PUBLICATION YEAR: 2001 LANGUAGE: English LANGUAGE OF SUMMARY: English Abstract: Interstitial water, extracted from the bottom sediment of a shrimp culture pond, was rich in nutrients containing total phosphorus with concentration of 25.98 mg/l and total nitrogen of 65.45 mg/l. A diatom, Chaetoceros calcitrans, a green alga, Nannochloropsis oculata, and a cyanobacterium, Oscillatoria sp., were cultured in pure interstitial water (PIW), diluted interstitial water (DIW) and in Conway medium (CM). C. calcitrans showed a significantly higher (P < 0.05) growth rate in DIW compared to CM and PIW. Alternatively, Oscillatoria sp. had a significantly lower (P < 0.05) growth rate when grown in DIW compared to CM. Similar to the other algae, Oscillatoria sp. showed the lowest growth rate in PIW. C. calcitrans and Oscillatoria sp. were also grown in DIW with the addition of nitrogen, phosphorus, silica and the combination of the three nutrients. The addition of nitrogen and silica to the diluted interstitial water significantly improved (P < 0.05) the growth rate of C. calcitrans, but the addition of phosphorus significantly decreased (P < 0.05) its growth. On the other hand, the growth rate of Oscillatoria sp. significantly decreased (P < 0.05) with the addition of nitrogen, but increased (P < 0.05) with the addition of phosphorus. There was no significant difference (P < 0.05) in the growth rate of Oscillatoria sp. cultured in interstitial water and that with added silica or a combination of nitrogen, phosphorus and silica. This study indicates that interstitial water extracted from aquaculture ponds, in sterilized diluted form, has the potential to be used as an effective medium for the culture of microalgae.
