Numerical investigation of shell-side heat transfer in helically coiled tube heat exchangers: morpho-hydrodynamic effects and a data-driven multivariable Nusselt-number surrogate

Purpose This paper aims to investigate shell-side convective heat transfer in a vertically oriented helically coiled tube heat exchanger (HCTHEX) and develop a multivariable within-domain surrogate for the shell-side Nusselt number under fluid-to-fluid operation. Design/methodolo...

Estimating temporal (2019–2025) and regional effects on Minnesotans' attitudes toward wolf hunting

Public attitudes toward wolf hunting are important for developing socially responsive wolf management policy. Drawing on two representative surveys of state residents, this study examined change in Minnesotans' (USA) support for wolf hunting in 2019 and 2025. We found that slight...

A Model for Community-Engaged and Relational Approach to Qualitative Data Analysis

Little has been written on how qualitative research can effectively include community participant perspectives, interpretations, and feedback during analysis. When conducting community-based participatory research (CBPR) with historically marginalized communities, incorporating c...

When contextual backgrounds backfire: a multi-study investigation of visual design effectiveness in digital marketing

Purpose Digital marketers routinely decide whether products should appear in contextual usage settings or isolated on neutral backgrounds, yet platform practices and prior research offer mixed guidance. This research examines when contextual backgrounds improve or undermine digit...

Predictability of exergy destruction in helically coiled tube heat exchangers: global, pitch-specific and hierarchical correlations

Purpose This study aims to quantify second-law performance in a vertically oriented helically coiled tube heat exchanger (HCTHEX) and develop predictive correlations for the dimensionless exergy-destruction fraction ϕD=E˙D/E˙in,total across operating conditions and coil pitches,...

Adapting Maslow’s Hierarchy of Needs to a student advising framework

Abstract This AM Last Pages describes how Maslow’s Hierarchy can help students understand the myriad of tasks they must complete from a career perspective in medical school. These 5 distinct tasks include finishing medical school intact, meeting minimum standards to finish school...

Optimizing the radiolytic degradation of aspirin and acetaminophen in aqueous solutions using a Rhodotron electron-beam accelerator and central composite design

The escalating pollution of limited freshwater resources by ECs represents a critical byproduct of modern industrialization. Pharmaceutical compounds, specifically NSAIDs like ACM and ASP, are frequently detected in aquatic environments because conventional wastewater treatment p...
