Wood units · m2 or Wood units/m2: does it matter?

As we know that, the Fick principle involves many limitations. Most important concern is measuring oxygen consumption (VO2) for Fick calculation. However, direct measurement of VO2 is difficult and expensive. Therefore, it has been generally accepted that, predicted VO2 values can be use in practice (1). A table has been published in European Society of Cardiology (ESC) Guideline which is point...

‘ Fire hardening ’ spear wood does slightly harden it , but makes it much weaker and more

It is usually assumed that ‘fire hardening’ the tips of spears, as practised by hunter–gatherers and early Homo spp., makes them harder and better suited for hunting. This suggestion was tested by subjecting coppiced poles of hazel to a fire-hardening process and comparing their mechanical properties to those of naturally seasoned poles. A Shore D hardness test showed that fire treatment slight...

Does replacing coal with wood lower CO2 emissions? Dynamic lifecycle analysis of wood bioenergy

Bioenergy is booming as nations seek to cut their greenhouse gas emissions. The European Union declared biofuels to be carbon-neutral, triggering a surge in wood use. But do biofuels actually reduce emissions? A molecule of CO2 emitted today has the same impact on radiative forcing whether it came from coal or biomass. Biofuels can only reduce atmospheric CO2 over time through post-harvest incr...
