Air Pollution Quinones Impair Intestinal Barrier Integrity and Endoplasmic Reticulum in Differentiated Caco‐2 Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Particulate matter (PM) is a major global health threat, linked to millions of deaths annually. Beyond inhalation, PM components reach the gastrointestinal tract through the mucociliary escalator or contaminated food and water. Among PM's organic fraction, redox‐active quinones such as 1,2‐naphthoquinone (NQ) and 9,10‐phenanthrenequinone (PQ ...

The Influence of Diesel Oil Improvers on Indices of Atomisation and Combustion in High-Efficiency Engines

Polish Maritime Research, 2017
The process of fuel combustion in a diesel engine is determined by factors existing during liquid fuel injection and atomisation. The physicochemical properties of the fuel to a large extent decide upon the quality of this phase of cylinder fuelling.

Combustion and Emissions Characteristics of Diesel Engine Operating on Composite Combustion Mode of DME and Diesel

Proceedings of the 1st International Conference on Mechanical Engineering and Material Science, 2012
Combustion and emissions characteristics were investigated on a common rail turbocharged diesel engine operating in the composite combustion mode of Homogeneous charge of DME and diesel fuel injection. The results indicate that under a certain amount of premixing of DME with intake air, the maximum of cylinder pressure and pressure rise rate increase ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Affordable and Clean Energy: CO2 Emissions, Resilience and Inequality

Sustainable Development, EarlyView.
ABSTRACT Sustainable development means building the resilience of both people and the planet. It includes implementing strategies which reduce emissions while also enabling more vulnerable households to transition to clean and affordable energy. This paper examines household CO2 emissions in Ireland to highlight those who emit most and least in key ...
