...carbon dioxide (the main 'greenhouse gas') in the Earth's atmosphere is increasing and increasing the 'greenhouse effect' (i.e. heat is trapped by the atmosphere in the same way that heat in a greenhouse is trapped by the glass). Why is the amount of carbon dioxide increasing? Because of human activity such as burning fossil fuels, and also the destruction of rainforest...

...carbon fibre reinforced polymer (i.e. basically a plastic strengthened by strands of carbon), but both are examples of composite materials in that they have dissimilar materials working together. Wood has cellulose tubes with lining bonds whereas modern wheels have carbon fibres in an epoxy or polyester matrix (i.e. bonding plastic). Each provides a stiff, strong spoke...

Integrated safety, health and environmental management: An introduction

...Carbon in an abatement system fitted to a tank vent to adsorb emissions may undergo auto-ignition and lead to a flashback to the tank, resulting in an explosion. Walls around equipment to improve the working environment, such as to reduce noise from a compressor house, may allow gases to accumulate with resulting inhalation or fire risks. Similarly, walls on offshore...

The gut microbiome: balancing the body

...carbon dioxide; (b) The cells use the oxygen to generate energy in the mitochondria. Carbon dioxide is produced as a waste product. Recent research has shown that some elite endurance runners have an increase in a bacterial species called Veillonella. This species is thought to increase the amount of lactate that the athlete can tolerate, which in turn is linked to the...

Dim ond 10% o’r llygredd carbon yn ein hamgylchedd y mae’r 3.9 biliwn o bobl dlotaf wedi’i gyfrannu (Maslin, 2021). Mae rhai pobl wedi teimlo bod angen gweithredu yn erbyn argyfwng hinsawdd. Un ffigur pwysig yw Greta Thunberg. Yn 2018, dechreuodd...

...carbon, oxygen and hydrogen. To enable cellular components such as organelles to be viewed, the sections must first be 'stained' to increase contrast. However, unlike light microscopy, which uses coloured stains that absorb light, in TEM, the stains contain heavy metals, such as lead and uranium. These are large atoms that prevent electrons passing straight through the...

...carbon emissions, set against the difficulties of obviously the radioactive waste. I am broadly in favour of phasing out nuclear, because I think renewables are the way to go, but that’s my own personal view. RH: When you look at this whole sphere, energy, climate, all that stuff, how optimistic are you? TE: I’m an optimist in the sense that I think humans are...
