Relations on the River Beane. Health and public intimacy in an era of uncertainty
No full textThis thesis traces the multiple ways in which individuals relate to the River Beane, an increasingly waterless chalk stream in Hertfordshire, South-East England. It notes how a sense of uncertainty which is social, environmental, climactic, and now too pandemic, comes to be reflected on, experienced through, and in some cases produced by virtue of these local river relations. Based on sixteen months of multi-sited ethnography the thesis engages anthropological theory and methods – with geography, history, and interdisciplinary social science work – to shed light on the myriad ways in which peoples in Hertfordshire, through these relations, come to question authoritative ways of knowing and enacting health for the river, its non-human life, and the humans connecting in and through it. In the first of three data chapters, concerned local parties decry the death of the River Beane. Death here is enacted as a narrative, metaphor, and as a powerful call to arms, aligning the River Beane with a wider politics of chalk streams in ‘crisis’, and lobbying for more connective, more-than-human relationships for the future. The second data chapter traces encounters of boundary maintenance and health-as-separation, discussing their temporal, spatial, and species inflections, and noting how the uncertainty wrought by the coronavirus worked to disrupt them. The final data chapter homes in on peoples traversing the boundary of land and water, exploring the relationship between rising numbers of river swimmers on the River Beane, a time of pandemic uncertainty, and emerging enactments of health. The discussion proposes an analytic of public intimacy to make sense of these river engagements as embodied desires for connections which are more-than-human, more than individual, and through which health can be sought and experienced as something connective, intimate, and public

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
Fabrication of ZnO Thin Films from Nanocrystal Inks
No full textZinc oxide nanocrystals were prepared in ethanol and spin-cast to form semiconductor nanocrystal thin films
that were thermally annealed at temperatures between 100 and 800 °C. Particle size, monodispersity, and
film porosity were determined by X-ray diffraction, ultraviolet-visible absorption spectroscopy, and
spectroscopic ellipsometry, respectively. Film porosity rapidly decreased above 400 °C, from 32% to 26%,
which coincided with a change in electronic properties. Above 400 °C, the ZnO electron mobility, determined
from FET transfer characteristics, increased from 10-3 to 10-1 cm2 V s-1, while the surface resistivity,
determined from electrical impedance, decreased from 107 to 103 Ω m over the same temperature range.
Below the densification point, nanoparticle core resistivity was found to increase from 104 to 106 Ω m, which
is caused by the increasing polydispersity in the quantized energy levels of the nanocrystals. From 100 to
800 °C, crystallite size was found to increase from 5 to 18 nm in diameter. The surface resistance was decreased
dramatically by passivation with butane thiol

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.
