Autod on järjest enam kättesaadavamad ja see suurendab linnade öhusaastet ja mürataset. Autode heitgaaside kahjulikkuse peamiseks pöhjuseks on see, et pölemisprotsess kestab auto silindris ainult sekundi murdosa vältel ja heitgaaside sekka satub palju mürgiseid löpuni oksüdeerimata aineid. Lancasteri ülikooli teadlaste uuring viitab, et puud, pöösad ja muud taimed suudavad pilvelöhkujate vahel öhusaastega vöidelda hoopis töhusamalt kui seni arvatud. Thomas Pugh ja tema kolleegid väidavad, et pilvelöhkujate vahele istutatud rohelus suudab vähendada lämmastikdioksiidi kontsentratsiooni kuni 40 protsenti ja peente osakeste kontsentratsiooni tänaval kuni 60 protsenti.

HUVITAVAID FAKTE Värvipimedad jahimehed eristavad loomi segase tausta juures paremini. Värvipimedad sõdurid näevad mõnikord kamuflaazi, mis normaalse värvitajuga inimesed ära petab. On mitmeid värvipimedaid kunstnikke, kelle värvitajuhäire neid sugugi tööd tegemast ei sega. Näiteks Clifton Pugh. Tänan kuulamast! KASUTATUD KIRJANDUS Color perception test.

in 1819 and used it for aqueducts, abutments, culverts, and lock walls. In 1831, Lebrun, a French engineer, designed the first concrete bridge to span the River Agout, although it never was built. A significant early structural use of concrete in the USA was in 1848 for the foundations and deck of the Starrucca Viaduct on the New York & Erie Railroad, a mighty stone- arched bridge with an overall length of 1040ft (317m), designed by Julius Walker Adams and built by James Pugh Kirkwood. Later, the use of artificial cement combined with more sophisticated understanding of the mathematical principles of arch theory resulted in renewed interest in stone and masonry arch bridges in Europe. Beginning in the mid-19th century, masonry railroad viaducts were an important civil engineering technology for continental Europe. The most impressive were the 1969ft (600m) long Chaumont Viaduct (1857) and the 240ft (73m) high Sainte-Brieuc (Barentin) Viaduct (1860),
