A dry-seal gasholder can be designed to have a gross (geometric) volume ranging from 200 to 165,000 m 3 (7,100 to 5,826,900 cu ft), whilst having a working pressure range between 15 and 150 millibars (1.5 and 15.0 kPa). The dry-seal gasholder is finished with an anti-corrosive treatment to counteract local climatic conditions and also any ...

3. Cosm insists this is not a theater "We're allergic to the term theater," Poolman says. Cosm's creators want the spaces to feel social. That's why they also sell a low-priced general admission ...
The prism fusion range ( PFR) or fusional vergence amplitude is a clinical eye test performed by orthoptists, optometrists, and ophthalmologists to assess motor fusion, specifically the extent to which a patient can maintain binocular single vision ( BSV) in the presence of increasing vergence demands. Motor fusion is largely accounted to ...
The Perseid meteor shower peaked in the night skies of Sunday into Monday, giving astronomy fans one of the best shows of 2024 as they looked to the skies.
