Academic patenting: the importance of industry support
This paper provides evidence that university-industry collaboration is important for turning commercial opportunities into patents. The results suggest that researchers who receive a large share of research grants from industry have a higher propensity to file a patent. Small dissemination grants generally exert a positive effect, whether they come from industry or not. It also finds that these interactions do not increase the number of industry owned patents alone but benefit universities’ commercialisation efforts in general
Emission of carbon monoxide, total hydrocarbons and particulate matter during wood combustion in a stove operating under distinct conditions
Wood combustion experiments were carried out to determine the effect of ignition technique, biomass load and
cleavage, as well as secondary air supply, on carbon monoxide (CO), total hydrocarbon (THC), particulate matter
(PM10) and particle number emissions fromawoodstove.Wood fromtwo typical tree species in the Iberian Peninsula
was selected: pine (Pinus pinaster) and beech (Fagus sylvatica). The highest CO and total hydrocarbon
emission factors (EFs) were observed, respectively, for pine and beech, for high and low fuel loads. The highest
PM10 EFwas recorded for the operationwith lowloads for bothwoods. Secondary air supply produced the lowest
PM10 emission factors. The top ignition can decrease the PM10 EF to less than halfwhen compared with the common
technique of lighting from the bottom. The lowest particle number emission factors were observed when
operating with high loads of split beech logs and when using secondary air supply during the combustion of
pine. Regarding particle number distributions, the highest geometric mean diameter (Dg), for both woods,
were observed when operating with high loads (with split and non-split wood)
