Analysis of Readex's Serial Set MARC records: Improving the data for the library catalog

Colorado State University Libraries (CSUL) purchased the digitized United States Congressional Serial Set, 1817–1994 and American State Papers (1789–1838) from the Readex Division of NewsBank, Inc. and, once funds and records were available, the accompanying MARC records. The breadth of information found in the Serial Set is described, along with the difficulties in using the print version (incorporated in the literature review, which includes citations of announcements of the digital collections and reviews of the software). The digital version of the Serial Set has its advantages, but there are additional rewards (much greater discovery opportunities) when items in the digital collection are directly accessible from the library catalog. The purchased MARC records, while overall excellent, had problems that needed to be corrected before they were loaded into CSUL's Innovative Interfaces library catalog. Patron access impact was used as a criterion when determining which of the records would be fixed before loading. High impact problems were identified and solutions derived for: multiple 245 (title) fields; 245 s indicator zero with titles beginning with a, an, or the; dollar sign used in text; fixed field date; languages; subject headings; creating proxy URLs; classification numbers; and author authority control (e.g. corporate entries and presidential entry errors).     

An approach to optimize the batch mixing process for improving the quality consistency of the products made from traditional Chinese medicines

The efficacy of traditional Chinese medicine (TCM) is based on the combined effects of its constituents. Variation in chemical composition between batches of TCM has always been the deterring factor in achieving consistency in efficacy. The batch mixing process can significantly reduce the batch-to-batch quality variation in TCM extracts by mixing them in a well-designed proportion. However, reducing the quality variation without sacrificing too much of the production efficiency is one of the challenges. Accordingly, an innovative and practical batch mixing method aimed at providing acceptable efficiency for industrial production of TCM products is proposed in this work, which uses a minimum number of batches of extracts to meet the content limits. The important factors affecting the utilization ratio of the extracts (URE) were studied by simulations. The results have shown that URE was affected by the correlation between the contents of constituents, and URE decreased with the increase in the number of targets and the relative standard deviations of the contents. URE could be increased by increasing the number of storage tanks. The results have provided a reference for designing the batch mixing process. The proposed method has possible application value in reducing the quality variation in TCM and providing acceptable production efficiency simultaneously.     

丹贝(Tempe)发酵过程中的成分变化及其功能性

丹贝(Tempe)是一种传统的印度尼西亚发酵豆制品,比未发酵豆制品具有更多的生物活性成分.这主要是由于丹贝在发酵过程中发生了一系列的生物化学变化,主要体现在游离氨基酸、游离脂肪酸、B族维生素及生育酚、可溶性矿物质含量的增加,活性异黄酮苷元、SOD的产生,抗营养因子和胀气因子的有效去除.文章对发酵过程中的成分变化进行了具体综述,并对Tempe的功能性及其产品开发进行了探讨.

Improved elastase production by Bacillus sp.EL31410--further optimization and kinetics studies of culture medium for batch fermentation

An efficient culture medium producing a bacterial elastase with high yields was developed further following preliminary studies by means of response surface method. Central composite design (CCD) and response surface methodology were applied to optimize the medium constituents. A central composite design was used to explain the combined effect of three medium constituents, viz, glucose, K2HPO4, MgSO4@7H2O. The strain produced more elastase in the completely optimized medium, as compared with the partially optimized medium. The fitted model of the second model, as per RSM,showed that glucose was 7.4 g/100 ml, casein 1.13 g/100 ml, corn steep flour 0.616 g/100 ml, K2HPO4 0.206 g/100 ml and MgSO4@7H2O 0.034 g/100 ml. The fermentation kinetics of these two culture media in the flask experiments were analyzed. It was found that the highest elastase productivity occurred at 54 hours. Higher glucose concentration had inhibitory effect on elastase production. At the same time, we observed that the glucose consumption rate was slow in the completely optimized medium, which can explain the lag period of the highest elastase production. Some metal ions and surfactant additives also affected elastase production and cell growth.
