The thermal transport to drops that roll or slide down heated superhydrophobic surfaces is explored. High-speed infrared imaging is performed to provide time-resolved measurement of the heat transfer to the drop. Data are obtained for drops moving along smooth hydrophobic and structured superhydrophobic surfaces. Both post and rib style structures with surface solid fractions ranging from 0.06 to…
Aim(s) To examine gender-based disparities across each link of the American Heart Association's Chain of Survival for women experiencing out-of-hospital cardiac arrest, highlighting systemic, cultural and educational barriers that compromise equitable outcomes. Design A discursive review synthesizing epidemiological studies, public health data and qualitative research on cardiac arrest and gender…
CubeSats experience significant thermal loads due to solar irradiation and the dissipation from electrical components. The high heat dissipation per unit volume can lead to mission failure if not properly managed. Deployable radiators that are externally stowed and passively actuated in response to changes in CubeSat temperature have been explored as a viable solution. This work describes a…
Radiative surface properties play a critical role in the design, analysis and optimization of solar–thermal systems. Cavity receivers increase the efficiency of solar–thermal energy systems through the cavity effect. The cavity effect refers to increased absorption of radiation due to multiple reflections within a cavity. Apparent radiative surface properties of a cavity characterize the effective…
Accurate models for predicting drop dynamics, such as maximum drop departure sizes, are crucial for estimating heat transfer rates during condensation on superhydrophobic (SH) surfaces. Previous studies have focused on examining the heat transfer rates for SH surfaces under the influence of gravity or vapor flowing over the surface. This study investigates the impact of surface solid fraction and…
The mill behavior of a 312 Combustion Engineering Raymond Bowl Mill was studied with five blends of Utah bituminous coal and steam-exploded woody biomass, ranging from 100 % coal to 100 % biomass. Mill power consumption increased with biomass content, peaking at 187 % of the power required for 100 % coal before the mill faulted at 100 % biomass. After repositioning the rollers, power consumption…
Highly sensitive vertically aligned carbon nanotube arrays (VANTAs) interdigitated electrode (IDE) arrays are developed for electrochemical biosensing of two cytokines (i.e., interleukin-10 (IL-10) and interferon-gamma (IFN-𝜸)) that are useful for early detection Johne’s disease (Bovine Paratuberculosis) in cattle. The high aspect ratio VANTA-IDEs (50–60 μm in height) are grown through a chemical…
Background: Internationally, women continue to report health inequities that are increasingly being framed as medical misogyny, yet the linguistic mechanisms underpinning them remain understudied. Objective: To examine the discourse through which women's healthcare experiences are publicly framed and interpreted as medical misogyny. Methods: A 37,327-word corpus was constructed and analysed using…
Learning how to recognise and respond to disclosures of family violence is a core component of nurse education, yet this learning often occurs in classrooms and clinical environments where some students and educators may themselves be survivors. Across nursing programs, pedagogical approaches often emphasise recognising and responding to patients affected by family violence yet give limited…
In mental health care, the term 'hard-to-reach' is frequently used in relation to individuals and populations who have reduced access and engagement with services. While positioned as a neutral term, this term can conceal and minimise the multiple factors influencing access to and engagement with care. It also clearly places the responsibility for disengagement as an individual decision or…
