The impact of iodine oxide chemistry upon OH and HO 2 concentrations in the coastal marine boundary layer has been evaluated using data from NAMBLEX (North Atlantic Marine Boundary Layer Experiment) campaign, conducted at Mace Head, Ireland during summer 2002. Observationally constrained calculations show that under low NO x conditions experienced (NO ≤ 50 pptv), reaction IO + → HOI O accounted for up to 40% total radical sink, subsequent photolysis form I comprised 15% midday production...
Abstract. OH and HO2 concentrations were measured simultaneously at the Mace Head Atmospheric Research Station in summer of 2002 during NAMBLEX (North Atlantic Marine Boundary Layer EXperiment) field campaign. was by laser-induced fluorescence employing FAGE (Fluorescence Assay Gas Expansion) technique, with a mean daytime detection limit 2.7×105 molecule cm−3 (5 min acquisition period; signal-to-noise ratio = 1). detected as following its chemical conversion through addition NO, 4.4×106...
Abstract. A field instrument utilising the artificial generation of OH radicals in a sliding injector flow-tube reactor with detection by laser-induced fluorescence spectroscopy has been developed to measure rate decay reaction its atmospheric sinks. The reactivity calibrated using known concentrations CO, NO2 and single hydrocarbons flow zero air, impact recycling via HO2+NO→OH+NO2 on measured quantified. As well as detailed description apparatus, capabilities new are illustrated...
Abstract. The North Atlantic Marine Boundary Layer Experiment (NAMBLEX), involving over 50 scientists from 12 institutions, took place at Mace Head, Ireland (53.32° N, 9.90° W), between 23 July and 4 September 2002. A wide range of state-of-the-art instrumentation enabled detailed measurements the boundary layer structure atmospheric composition in gas aerosol phase to be made, providing one most comprehensive situ studies marine date. This overview paper describes aims NAMBLEX project...
A tuneable, high pulse-repetition-frequency, solid state Nd:YAG pumped titanium sapphire laser capable of generating radiation for the detection OH, HO2, NO and IO radicals in atmosphere by induced fluorescence (LIF) has been developed. The integration system operating at 308 nm into a field measurement apparatus simultaneous hydroxyl hydroperoxy is described, with limits 3.1 × 105 molecule cm−3 (0.012 pptv boundary layer) 2.6 106 (0.09 pptv) achieved OH HO2 respectively (30 s signal...

In this article, we propose (re)designing privacy literacy as an essential component of our digital lives in age Generative Artificial Intelligence (genAI). Our study emphasizes the layered digital, technical, rhetorical, and algorithmic literacies associated with design thinking genAI to support theorizing literacy. We introduce Design analytical element complementary Woods Wason's (2021) multi-pronged framework for analyzing Terms Service (ToS) documents. Using a cluster Adobe AI ToS,...
Purpose: Our article interrogates mobile ridesharing apps as sites where digital interfaces, cultural practices, and rhetorical discourses intersect. We establish counter- histories of conduct a critical interface analysis select to demonstrate how innovative interfaces imagine universal user while culturally specific make space for community-based experience (CBX). Method: This brings together Haas' rhetorics (DCR) framework with Brock's technocultural discourse (CTDA) zoom in on the...

Although much scholarship on community-engaged pedagogies attends to student negotiations of difference, little attention has been paid how instructors navigate particularly racial across classroom and community spaces. In this article, we use the concept brokering examine seven different a writing course titled “The Literacy Narratives Black Columbus” imagined racialized spaces facilitated engagement between students members in those Drawing primarily instructor interviews, present three...
In this essay, we offer the “investigative pivot” as a framework for teaching rhetoric researchers how to orient and withstand being re-/dis-/oriented by research process. Investigative pivoting indexes researcher responds material conditions under which they collect analyze data. To illustrate investigative pivots, present pivot narratives from four graduate student researchers. Drawing on analytic power of E. Cram’s orientation, these detail negotiate infrastructural, ideological,...
