MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Evaluation of in vitro activity of teicoplanin against recent clinical isolates.
No full textThe in vitro antibacterial activity of teicoplanin, a new glycopeptide antibiotic, previously named teichomycin A2, has been compared to that of five other chemoantibiotics: netilmicin, clindamycin, rifampicin, enoxacin and vancomycin. The minimum inhibitory concentration (MIC) values against 588 gram-positive strains, 561 facultative aerobes and 27 anaerobes, recently isolated from clinical specimens, were evaluated. Teicoplanin showed the highest activity against all the tested strains, with a geometrical mean of the MICs (GMM), a MIC50 and MIC90 of 0.123, 0.12 and 0.5 micrograms/ml respectively
Optimal regulation of pumping station in water distribution networks using constant and variable speed pumps: A technical and economical comparison
No full textGreenhouse gas emission is one of the main environmental issues of today, and energy savings in all industries contribute to reducing energy demand, implying, in turn, less carbon emissions into the atmosphere. In this framework, water pumping systems are one of the most energy-consuming activities. The optimal regulation of pumping systems with the use of variable speed drives is gaining the attention of designers and managing authorities. However, optimal management and operation of pumping systems is often performed, employing variable speed drives without considering if the energy savings are enough to justify their purchasing and installation costs. In this paper, the authors compare two optimal pump scheduling techniques, optimal regulation of constant speed pumps by an optimal ON/OFF sequence and optimal regulation with a variable speed pump. Much of the attention is devoted to the analysis of the costs involved in a hypothetical managing authority for the water distribution system in order to determine whether the savings in operating costs is enough to justify the employment of variable speed drives
