Annular Flume

Flumes have been widely used in water conservancy science and environmental science research. It is of great significance to obtain the hydrodynamic characteristics and flow field uniformity in the flume. In this study, a new type of annular flume was taken as an example. The 3D flow field was simulated by using a commercial computational fluid dynamics (CFD) code, and was also measured by acoustic doppler velocimeter (ADV) to verify the simulation results. The average relative error range was between 8.37% and 9.95%, the simulated results basically reflected the actual situation of the flow field. On this basis, the structural characteristics of flow field were analyzed. A new calculation method of flow velocity uniformity was presented according to the flow characteristics of natural open channels. The velocity uniformity in the straight channel was calculated and analyzed based on this method, and the influence of speed on the velocity uniformity was further discussed. The length of uniform section was negatively correlated with the rotational speed (average velocity), which was between 39 cm and 101 cm in the straight, and the uniformity coefficient was less than 10%. Finally, the water flow characteristics in the straight channel without wheel were compared with the natural open channel flow. The longitudinal velocity was well fitted with the Prandtl logarithmic distribution formula (R2 > 0.977), and the application feasibility of the flume was analyzed. This study can provide technical support for the development and application of annular flume.

Purpose This study aims to find out the average journal packing density (JPD) of Library and Information Science (LIS) research journals published across the world. The concept, JPD, means the average number of research articles published by a research journal in one volume. Accordingly, the undergoing study evaluates the average number of research articles published in each volume of each research journal published in the field of LIS at the global level. Some other key aspects evaluated include the number of LIS research journal publishing countries, average JPD of LIS research journals at the continental level, etc. Design/methodology/approach This study is purely based on secondary data retrieved from SCImago, which is SCOPUS data. Keeping in view the objectives of this study, the data about research articles published in all LIS research journals during the period 2015 through 2019 were retrieved to undertake the study. Findings From the data analysis, it emerged that 256 research journals duly indexed by SCOPUS are published in the field of LIS across 36 countries. In all 48,596 research articles were published from 2015 to 2019 in these research journals at an average of 44.71 research articles per journal per volume. More than 75% of LIS research journals are published from Germany, Spain, Netherlands, the USA and the UK. Research journals published from the USA have higher JPD of 53.09 research articles per journal per volume, which is 18.74% higher than the average global JPD of LIS research journals. 50% of LIS research journal publishing countries are from Europe and the majority 52.55% LIS research articles were published in European LIS research journals. The average JPD of LIS research journals published from North America is 51.73 research articles per journal per volume, which is the highest across continents. Research limitations/implications Standardization of JPD of research journals irrespective of the subject discipline they are published in is important for many reasons and the foremost being, such standardization helps in keeping at bay the predatory research journals, which normally float such packing density norms, with the sole aim to earn money in the shape of manuscript handling charges, thereby publishing a far greater number of research article in each issue of a journal than the average research articles published by a research journal. Originality/value Very few studies have been conducted around the concept JPD, especially by the authors of this particular study. This study has however been particularized to the LIS subject discipline, while the findings add to existing lot of study already undertaken, hence outcome can be generalized.

A Review of: Enger, K. B. (2009). Using citation analysis to develop core book collections in academic libraries. Library & Information Science Research, 31(2), 107-112. Objective – To test whether acquiring books written by authors of highly cited journal articles is an effective method for building a collection in the social sciences. Design – Comparison Study. Setting – Academic library at a public university in the US. Subjects – A total of 1,359 book titles, selected by traditional means (n=1,267) or based on citation analysis (n=92). Methods – The researchers identified highly-ranked authors, defined as the most frequently cited authors publishing in journals with an impact factor greater than one, with no more than six journals in any category, using 1999 ISI data. They included authors in the categories Business, Anthropology, Criminology & Penology, Education & Education Research, Political Science, Psychology, Sociology/Anthropology, and General Social Sciences. The Books in Print bibliographic tool was searched to identify monographs published by these authors, and any titles not already owned were purchased. All books in the study were available to patrons by Fall 2005. The researchers collected circulation data in Spring 2007, and used it to compare titles acquired by this method with titles selected by traditional means. Main Results – Overall, books selected by traditional methods circulated more than those selected by citation analysis, with differences significant at the .001 level. However, at the subject category level, there was no significant difference at the .05 level. Most books selected by the test method circulated one to two times. Conclusion – Citation analysis can be an effective method for building a relevant book collection, and may be especially effective for identifying works relevant to a discipline beyond local context.
