Aerosol vs injected epinephrine in acute asthma
Annals of Emergency Medicine, 1981Twenty-five patients with acute asthma were randomized prospectively into one of two double-blind treatment regimens: regimen 1 consisted of subcutaneous epinephrine combined with aerosol placebo; regimen 2 consisted of aerosol epinephrine with injected placebo.

Pros and cons of stratospheric aerosol injection
International Journal of Global Warming, 2020Solar radiation management (SRM) geoengineering method of stratospheric aerosol injection (SAI) has been proposed to control global warming. The effect of sulphur injections at various locations in the stratosphere are studied by using climate models. These climate models have well-known limitations that are non-adequately addressed in the manuscript ...

The impacts of Stratospheric Aerosol Injection on Antarctic ice loss depend on injection location
2023Owing to increasing greenhouse gas emissions, the West Antarctic Ice Sheet as well as a few subglacial basins in East Antarctica are vulnerable to rapid ice loss in the upcoming decades and centuries, respectively. This study examines the effectiveness of using Stratospheric Aerosol Injection (SAI) that minimizes global mean temperature (GMT) change to

Stratospheric aerosol injection research and existential risk
Futures, 2018Abstract In the wake of the continued failure to mitigate greenhouse gases, researchers have explored the possibility of injecting aerosols into the stratosphere in order to cool global temperatures. This paper discusses whether Stratospheric Aerosol Injection (SAI) should be researched, on the controversial ethical assumption that reducing ...

Stepwise injection photometric determination of nickel in air aerosols
Journal of Analytical Chemistry, 2012A procedure is developed for the automated determination of nickel in air aerosols; it involves the adhesive separation of aerosols on a fiberglass column in the on-site mode followed by the photometric determination of analytes with dimethyl glyoxime under the conditions of stepwise injection analysis of aerosol concentrates.

Studying gas temperature variation upon aerosol injection
Technical Physics Letters, 2017Variation of the temperature of gaseous combustion products upon pulsed injection of aqueous aerosols (water, NaCl solution, clay suspension) with droplet sizes within 40–400 μm has been experimentally studied at initial gas temperatures from 520 to 910 K.

Carbon Emissions, Stratospheric Aerosol Injection, and Unintended Harms
Ethics & International Affairs, 2017AbstractIn the rapidly expanding literature on the ethics of climate engineering, a lot has been made of the fact that stratospheric aerosol injection would for the first time create a world whose climate had been intentionally shaped by deliberate human decisions. Intention has always mattered in ethics. Due to the importance of intention in assigning

Legacy of stratospheric aerosol injection for limiting global warming
Despite significant advances in low emissions and renewable technologies, global warming is expected to exceed 2 degree and breach the Paris Agreement. Here we applied an Earth system model to simulate stratospheric aerosol injection (SAI) in idealized overshoot scenarios. The objective is to evaluate the impacts of avoiding temperature overshoot usingJerry Tjiputra +5 more
