Greenhouse effect

Some heat energy from the Earth’s surface escapes into space. If too much heat energy escaped, the planet would be very cold. However some gases in the atmosphere can trap escaping heat energy, causing some of it to pass back to the surface.

These are called greenhouse gases, and they keep our planet warm, which is a good thing. Carbon dioxide is an important greenhouse gas.

Increasing carbon dioxide levels

Humans burn fossil fuels such as oil, coal and natural gas. The energy released is used to power cars and other machines, to generate electricity, and to keep buildings warm. The burning fuel releases waste gases, including carbon dioxide. As the human population increases, more fuel is used, and more carbon dioxide is released.

Global warming

The extra carbon dioxide increases the greenhouse effect. More heat is trapped by the atmosphere, causing the planet to become warmer than it would be naturally. The increase in global temperature this causes is called global warming.

frozen elephant trunk for aortic arch reconstruction is associated with reduced mortality as compared to conventional techniques
wariber [46]

To compare the perioperative results of frozen elephant trunk (FET) vs. traditional elephant trunk (ET) procedures for aortic arch repair. 390 individuals had aortic repair with elephant trunk reconstruction between 2002 and 2018 at 9 facilities: Aortic dissection affected 37% of patients who received a FET (mean age: 65+/-13 years, 30% female), while 43% of patients who received an ET (mean age: 63+/-13 years, 37% female) experienced aortic dissection. In-hospital mortality, stroke, and spinal cord injury were among the outcomes of interest (SCI).

<h3>What is Aortic arch ?</h3>

The top portion of the principal artery sending blood away from the heart is known as the aortic arch. A combination of symptoms and signs known as aortic arch syndrome are linked to anatomical issues in the arteries that branch off the aortic arch. The valves, chambers, and accompanying vessels that make up the heart's interior.

<h3>What is conventional techniques ?</h3>

Conventional methods assess the long-term heat stability of polymer products at temperatures below their melting points, for instance, through accelerated aging in "circulating air ovens" until degradation effects like discolouration and embrittlement become apparent.

gavmur [86]

Answer:

The presence of predators of deer which does not allow increase in the population of deer year after year.

Explanation:

In an forest ecosystem, one animal controls the population of another organisms and thus there is no increase in the population of that organism and the ecosystem is in equilibrium state. The population of deer did not increase due to the presence of predators such as lion, cheetah etc and the net population is 0.
