RT-qPCR Data (raw, merged, normalized and analyzed) associated to the evaluation of the preventive treatments for intestinal mucositis in a murine model using Lacticaseibacillus rhamnosus L156.4 and Lacticaseibacillus rhamnosus GG
No full textAll RT-qPCR data were generated from a murine model of 5-fluorouracil (5-FU)-induced intestinal mucositis. BALB/c mice were treated daily for 13 days with 200 µL of either live, heat-inactivated, or culture supernatant preparations of Lacticaseibacillus rhamnosus L156.4 or LGG (ATCC 53103), or PBS as control. Mucositis was induced on day 11 via intraperitoneal injection of 5-FU (300 mg/kg). Animals were euthanized 72 hours post-induction. RNA was extracted from the distal ileum, reverse-transcribed to cDNA, and used in SYBR Green-based qPCR assays targeting markers of intestinal barrier function (e.g., Ocln, Cldn2, Tjp1), mucin production (Muc2), inflammation (Tnf, Il1b, Il6, Nfkb1), and immunoregulation (Il10, Tgfb1), normalized to Actb. Dataset includes raw Ct values and normalized expression values (ΔΔCt)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full textVariations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Prediction of gas–liquid flow in an annular gap bubble column using a bi-dispersed Eulerian model
No full textWe present and discuss numerical results from simulations of the air–water flow in an annular gap bubble column of 0.24 m internal diameter, at air superficial velocities ranging from 0.004 m/s to 0.225 m/s, covering the homogeneous and heterogeneous flow regimes. A bi-dispersed Eulerian model is implemented to account for both the stabilizing and destabilizing effects of small and large bubbles. Sensitivity studies on the mesh element size, time step size and number of outer iterations per time step are performed and most appropriate simulation parameters and mesh are used to predict the gas holdup curve. Comparison with two mono-dispersed models is provided to emphasize the necessity of a bi-dispersed approach for the accurate prediction of the homogeneous flow regime, given the poly-dispersed nature of the flow investigated. Two different approaches for the characterization of the small and large bubbles groups are also discussed. We found that the relative amount of small bubbles is an important input parameter for the present model and can be provided using available empirical correlations or experimental data. The results obtained from the simulations also demonstrated the necessity of a population balance model able to capture the bubbles coalescence and breakup phenomena for the correct prediction of the heterogeneous flow regime
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Numerical modeling of bubbly flow in square column
No full textBubble columns are widely used in the energy, chemical and biochemical process industry. In this paper, a square bubble column is studied by performing 3D transient simulations within the Eulerian–Eulerian approach. The commercial code ANSYS Fluent Release 14.5.7 has been used. Simulations have been performed to understand the sensitivity of different interphase exchange forces (drag, lift, turbulent dispersion, wall lubrication and virtual mass forces). The numerical results have been compared with experimental data from the literature. The nature of the drag coefficient is found to have a significant effect on the global hydrodynamics. The inclusion of a lift force is found to be necessary to obtain a local axial velocity distribution that is consistent with the experimental measurements. The inclusion of a turbulent dispersion force is fount to improve the modelling accuracy. The wall lubrication force enhances the predictions of the recirculation pattern. The virtual mass force is also discussed. Finally, recommendations on suitable closures are give
