Cable Stayed Bridges

An accurate numerical analysis of the behavior of long-span cable-stayed bridges under environmental effects is a challenge because of complex, uncertain and varying environmental meteorology. This study aims to investigate in-situ experimental structural behavior of long-span steel cable-stayed bridges under environmental effects such as air temperature and wind using the monitoring data. Nissibi cable-stayed bridge with total length of 610m constructed in the city of Adıyaman, Turkey, in 2015 is chosen for this purpose. Structural behaviors of the main structural elements including deck, towers (pylons) and cables of the selected long span cable-stayed bridge under environmental effects such as air temperature and wind are investigated by using daily monitoring data. The daily variations of cable forces, cable accelerations, pylon accelerations and deck accelerations with air temperature and wind speed are compared using the hottest summer (July 31, 2015) and the coldest winter (January 1, 2016) days data.

Capacité Photosynthétique

Six-week-old tomato plants (Lycopersicon esculentum Mill. ’Vendor’) were maintained at five root temperatures (12, 18, 24, 30 or 36 °C) and five night air temperatures (8, 12, 16, 20 or 24 °C) for a period of 4 wk. Increase in root temperature partly offset the negative effects of low night air temperature on leaf dry weight and leaf area. Our results showed that higher root temperatures (30 °C) are required at low night air temperature (8 °C) for optimum plant growth. Lower rates of plant photosynthesis at low root and/or night air temperatures resulted mainly from reduced leaf growth and expansion, but also from a decrease in the photosynthetic capacity of the leaves. Our results suggest combining split-night temperature and soil warming techniques to improve the productivity of tomato plants and to reduce greenhouse heating costs.Key words: Tomato substrate, temperature, photosynthesis, growth
