The Ozone Layer and Metered Dose Inhalers [PDF]

Canadian Respiratory Journal, 1998
The stratospheric ozone layer plays a crucial role in protecting living organisms against ultraviolet radiation. Chlorofluorocarbons (CFC) contained in metered‐dose inhalers (MDIs) contribute to ozone depletion and in accordance with the Montreal Protocol on Substances That Deplete the Ozone Layer established 10 years ago, phase‐out strageies have been

Goal Displacement and Goal Conflicts in Circular Innovation Initiatives: Types and Mitigation Practices

Business Strategy and the Environment, EarlyView.
ABSTRACT Many firms set ambitious sustainability goals but these are frequently “displaced” by proxy goals that are easier to track and measure. However, the specific types of goal conflicts that follow from this displacement are poorly understood. We conducted a case study of circular innovation initiatives at a global MedTech company and identified ...

Multi‐Objective RSM Optimization of Emission and Performance Characteristics in a Diesel Engine Fueled With BaTiO3 Nano‐Enhanced Jojoba Biodiesel

Energy Science &Engineering, EarlyView.
This study uses response surface methodology to optimize Jojoba biodiesel blended with BaTiO3 nanoparticles in a single‐cylinder diesel engine. Results show that ~48.95–51.31 ppm of BaTiO3 achieves balanced performance and emission, decreasing CO and NOx while increasing torque and brake thermal efficiency.

The bronchoprotective efficacy of salbutamol inhaled from a new metered-dose powder inhaler compared with a conventional pressurized metered-dose inhaler connected to a spacer [PDF]

, 1998
The aim of this study was to compare the efficacy of 100 μg of salbutamol inhaled from a new metered-dose powder inhaler (MDPI, Leiras Taifun®, Finland) with that of a same dose of salbutamol inhaled from a conventional pressurized metered-dose inhaler ...

Warmed intravenous fluid administration attenuated a reduction in body temperature in anaesthetised horses

Equine Veterinary Journal, EarlyView.
Abstract Background Peri‐anaesthetic hypothermia is a well‐documented complication of general anaesthesia and is associated with prolonged recovery, impaired wound healing, and delayed coagulation. Fluid warmers can be used to mitigate heat loss, but there is little evidence supporting their effectiveness in equine anaesthesia.

Vehicle Fires: Significant Fire Hazard in Transportation Infrastructure

Fire and Materials, EarlyView.
ABSTRACT Vehicle flammability poses a critical threat to transportation infrastructure, with recent fires in depots, tunnels, and car parks highlighting systemic vulnerabilities. These incidents often result in the total loss of vehicles and buildings, revealing the inadequacy of current fire safety standards for vehicle materials.
