Investigating the properties of novel poly(2-hydroxyethyl methacrylate-co-methyl methacrylate) hydrogel hollow fiber membranes
No full textPoly(2-hydroxyethyl methacrylate-co-methyl methacrylate) hydrogel hollow fiber membranes were synthesized by a novel centrifugal-spinning methodology that resulted in new asymmetric wall morphologies, which in turn affected the mechanical and transport properties. Hollow fiber membranes were formed after polymerizing the comonomers, 2-hydroxyethyl methacrylate and methyl methacrylate, in an aqueous system under centrifugal forces. The concentration of methyl methacrylate in the comonomer and the concentration of redox initiators were investigated for their effects on membrane morphology, water content, Young's modulus, and diffusive transport. Both monomer composition and initiator concentration impacted the resulting asymmetric membrane morphology, which varied from a macroporous sponge to a microporous gel to a homogeneous gel. The hollow fiber membranes synthesized herein had equilibrium water contents between 42 and 57%, elastic moduli between 22 and 400 kPa, and effective diffusion coefficients between 10-7 and 10-9 cm2 s-1 for vitamin B12 and 10 kD dextran. The significant differences in both the moduli and the diffusion coefficients exhibited by these hydrogel membranes reflect differences in their intrinsic microstructures. Synthesis of hydrogel hollow fiber membranes using centrifugal force is a highly dynamic process; the membrane properties can be effectively tailored by controlling phase separation kinetics. These hydrogel hollow fibers are particularly attractive for soft tissue applications, such as nerve guidance channels, where biocompatibility, mechanical strength, and transport properties are determinants of device performance in vivo

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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

Variations on the Author
Full text link“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
