We compared various pollutant concentrations (PM1, PM2.5, PM10, PNC, BC) at four different urban microenvironments (MEs) in London (Indoor, IN; Traffic Intersection, TI; Park, PK; and Street Canyon, SC). The physico-chemical characteristics of particles were analysed, and the respiratory deposition doses (RDD) were estimated. Field measurements were conducted over a period of 121 days. The mean PM2.5 (PNC) concentrations were found to be 9.47 ± 7.05 (16366 ± 11815), 8.09 ± 4.57 (10951 ± 6445), 5.11 ± 2.96 (7717 ± 4576), 3.88 ± 3.06 (5672 ± 2934) μg m−3 (# cm−3) at TI, SC, PK and IN, respectively. PM2.5, PM10 and PNC exhibited a trend of TI > SC > PK > IN; higher concentrations for PM1 and BC were observed at IN than PK due to the emissions from printers, producing a trend of TI > SC > IN > PK. We observed 12%–30% higher fine PM concentrations at TI and SC sites during morning peak (07:00–09:30) than the evening peak hours (16:00–19:00); while IN sho
With a new low price for the base model, and two peppy processor options, Apple's Mac mini offers a huge upgrade in capability while looking the same as ever. (Some good things don't need to change.)
Notebookcheck is testing the Intel NUC 12 Pro Kit, equipped with the Intel Core i7-1260P. We also installed 16 GB of RAM and a 512-GB SSD in the barebone. Additionally, we are taking a look at the gaming capabilities when paired with an external GPU.
The latest in a long line of impressive Intel NUC mini PCs, the NUC 12 Pro offers solid punch, good customizability, and plenty of connections, all in a classic subcompact chassis.
