We have isolated and characterized the cDNA and genomic DNA coding for a phenoloxidase, laccase I, previously purified from culture supernatant of the newly isolated ligninolytic basidiomycete PM1 (CECT 2971). A cDNA library from basidiomycete PM1 was constructed, and laccase-encoding cDNAs were identified by screening with antiserum raised against the purified enzyme. The lac1 gene coding for ...

[1] An Aerodyne aerosol mass spectrometer (AMS) was deployed at the Pittsburgh Environmental Protection Agency Supersite from 7 to 22 September 2002 as part of the Pittsburgh Air Quality Study (PAQS). The main objectives of this deployment were to characterize the concentrations, size distributions, and temporal variations of nonrefractory (NR) chemical species in submicron particles (approxima...

We have characterized the chemical composition and sources of submicron aerosol (PM1) at a suburban site in Xinzhou in central China using an Aerosol Chemical Speciation Monitor from July 17 to September 5, 2014. The average (±1s) PM1 concentration was 35.4 (±20.8) mg/m3 for the entire study period, indicating that Xinzhou was less polluted compared to the megacities in the North China Plain (N...

UNLABELLED Oxidative stress generation is a primary mechanism mediating the effects of Particulate Matter (PM) on human health. Although mitochondria are both the major intracellular source and target of oxidative stress, the effect of PM on mitochondria has never been evaluated in exposed individuals. METHODS In 63 male healthy steel workers from Brescia, Italy, studied between April and May...

PURPOSE In this study, the spatial and temporal relationship of wind speed, atmospheric particles concentration, and the industrial-induced noise levels during different times of the day were examined, using sawmill industrial location around Ile-Ife in Osun of Nigeria as a case study. METHODS Mobile devices were used to measure noise level and basic meteorological parameters were examined an...

Abstract. The dependence of aerosol acidity on particle size, location, and altitude over Europe during a summertime period is investigated using the hybrid version dynamics in chemical transport model PMCAMx. pH changes more with size northern southern owing to enhanced presence non-volatile cations (Na, Ca, K, Mg) larger particles. Differences up 1–4 units are predicted between sub- supermicr...

L.L. Maksimova and L. Esakia, V. Meskhi showed that the modal logic \({\mathcal {S}}4\) has exactly 5 pretabular extensions PM1–PM5. In this paper, we study problem of unification for all given logics. We PM2 PM3 have finitary, PM1, PM4, PM5 unitary types unification. Complete sets unifiers in logics are described.

The effect of intrinsic metal mineral elements in the combustion process pulverized coal on formation and transformation mechanism PM was investigated a drop-tube furnace air atmospheres at 1200 °C, which laid solid foundation for control particulate pollutants. results show that reducing evaporation or generated PM1 aggregating to form PM1–10 particles bigger than 10µm can reduce emission proc...
