One admittedly crude measure of technological prowess is the number of patents registered by a country.
When human population levels were low and technological abilities crude, societies' impact on the biosphere was relatively small.
Since there is a global trend of continuing increase in the consumption of biodiesel, it is necessary to search for different technological solutions for crude glycerin in order to add value to the productive chain of biodiesel within the biorefinery concept.
But to prevent any new fire and smoke episodes like the ones that have grounded its fleet, Boeing proposed the crudest tool in its considerable technological arsenal: the battery itself will be sealed inside a steel box that would serve as the last safety rampart if everything else fails.
Chevron added $1.89, to $91.78, after Goldman Sachs lifted its average 2008 forecast for crude oil to $95 from $85 a barrel on "technological and political uncertainty".
Economical assessment results show that the most appropriate technological scheme requires purifying the crude glycerol until 98 wt%, with a downstream process involving heat pretreatment, enzymatic-alkaline digestion, centrifugation, washing, evaporation, and spray drying.
David Musgrave achieves a weird meld of primitive and technological in his drawings, which surround crude little figures and amulets, seemingly made of paper or string, with the alien field of television static.
The 3-D boom of the '50s was driven in part by a technological advance — Edwin H. Land's polarized lenses replaced the crude red and green filters of the early processes — and partly by economic demands.
There is no technological fix available to shut off the flow of crude now streaming into the Gulf of Mexico And there is no way to clean the oil out of the water and off of all the beaches.
In this paper, the current and innovative technological solutions covering viscosity and friction reduction to move such crude oils from the production site to the processing facilities are thoroughly discussed.
