Fighting plastic pollution: An investigation into whether the presence or absence of single-use plastic impacts our impression of others
(University of Plymouth, 2021)The evidence is clear that plastic pollution is a huge problem threatening the survival of the modern world. Psychological researchers have risen to the challenge to investigate people's behaviours, attitudes and perceptions ... -
The effect of chlorhexidine mouthwash vs propolis mouthwash on the nitrate-reducing activity of oral bacteria and vascular control in healthy individuals
(University of Plymouth, 2021)Nitrate and nitrite molecules are involved in the synthesis of nitric oxide (NO), a gaseous vasodilatory molecule, via the nitrate-nitrite-NO pathway. Oral bacteria are responsible for the reduction of nitrate to nitrite ... -
An investigation into the determination of ammonium in mine bioleaching solutions utilising an ammonia gas electrode
(University of Plymouth, 2021)Fixed nitrogen is an essential nutrient for bacteria used in the mining industry to solubilise metals from their associated ores in a process known as bioleaching. Most bacteria are able to fix atmospheric nitrogen, but ... -
A study of the effect of heat treatments on EN9 steel - grain structure and mechanical properties
(University of Plymouth, 2021)Medium carbon steel 070M55, also known as EN9 or AISI/SAE 1055, was heat treated with five different heat treatment procedures to promote varying microstructures resulting in enhanced properties of the metal. The aim of ... -
Usability of Sentinel-3 satellite ocean colour data for examination and chlorophyll gradient classification of submesoscale island wake formations
(University of Plymouth, 2021)Submesoscale turbulent formations present challenges to sampling efforts due to their scale and transient nature. The development of successful sampling methods is imperative to achieving an understanding of the biological ... -
The use of novel lung alveolar macrophage model, Max Planck Institute cells, to demonstrate the differential effects of smooth and rough mycobacterium abscessus forms on IL-6 and IL-1B induction
(University of Plymouth, 2021)Mycobacterium abscessus frequently initiates respiratory infections in humans and is of clinical concern in patients with cystic fibrosis who develop secondary pulmonary infections. Alveolar macrophages and innate responses ... -
Development of a flow injection micro analysis system using an ARM microcontroller with an interactive web-based interface
(University of Plymouth, 2021)Monitoring the state of the environment is increasingly important in today's changing world. Flow Injection Analysis techniques are useful for measuring a wide range of solutions in a cost-effective and controlled manner. ... -
Producing a theoretical model for determining the appropriate propeller for a given model aircraft application
(University of Plymouth, 2021)This paper investigates a method of determining the most suitable propeller for any given model aircraft application based on simple inputs such as desired airspeed and powerplant requirements. This method has been embodied ... -
Analysing and improving the structural stiffness of the Triumph Vitesse
(University of Plymouth, 2021)The Triumph Vitesse is a British sports car built by British Leyland in the 1960s as a development from the Herald and sharing common design features with the Spitfire and GT6. Vehicle stiffness has a direct impact on ... -
Codeo - Learning support research: use of automated feedback within undergraduate programming education, a case study
(University of Plymouth, 2021)This paper describes the research process of a case study in the domain of pedagogical computer science, specifically in the context of how first year undergraduate students learn programming skills, with the purpose of ...
