Jee compared dark matter to crystal-clear water in a pond, with pebbles as the galaxies. “You cannot see the water unless there is wind, which causes ripples. Those ripples distort the shapes of the ...

In this paper we describe a method, the Time Correlation Tracer method, combining controlled tracer gas release from the landfill with time-resolved concentration measurements downwind the landfill ...

A team of scientists from the Institute of Applied Ecology of the Chinese Academy of Sciences has developed a novel method to ...

Methane (CH4), one of the most abundant natural gases on Earth, is still widely used to power several buildings and to fuel ...

Solar and wind energy are highly variable, dependent on the day, weather and location of the facilities. At times, they can ...

Environmental polycyclic aromatic hydrocarbons can prove dangerous if metabolites enter human systems. A new gas chromatography-based approach was developed to analyze the hydroxy derivatives in ...

Between 2021 and 2023, 100% of all executions in the U.S. were done by lethal injection. In the last year and a half, 16% have involved other methods.

Coal-fired power plants are among the largest contributors to global CO2 emissions. However, accurately measuring their emissions has been challenging due to outdated inventories and the technological ...

While the bill doesn't specifically name methods like firing squad, hanging, or nitrogen gas, it allows for their use if lethal injection drugs become unavailable.

Due to the nature of these compounds, gas chromatography coupled with a mass spectrometer is the preferred method of analysis. Learning Objectives: 1. Learn how to develop a analytical method for ...

Quantifying greenhouse gas emissions at various spatial scales, from hotspots in urban areas to expansive regional zones, is an integral task in mitigating ...
