Overview on FRB pre-stressed Tendons and its Fatigue Behavior
Authorized by Ahmed I Hassanin

Due to population growth and development of industry and transportation, the environment of human is started to become considerably polluted. Aggressive atmosphere and ground water increase the risk of corrosion of embedded reinforcement in concrete. The addition of waterproofing materials on concrete surface to minimize the amount of water and air that reaches the steel reinforcements through cracks. But waterproof materials are often expensive and need maintenance several times over the structure’s lifetime. The situation is more dangerous for pre-stressing tendons in pre-stressed bridges, deterioration of highway concrete bridges due to tendon corrosion has been large problem in many countries. Structural engineers dealing with durability of concrete greatly concern about possibilities to improve service life of embedded reinforcements.

Effect of Infrared Radiation on the Hydrogen in Thin Films Double Barriers Based Melt Silicone-Germany

Abstract Possibilities of plasma chemical deposition of α-Si 1-x Ge x :H (x=0÷1) films undoped and doped with PH 3 or B 2 H 6 have been analyzed from the viewpoint of their application in p-i-n structures of solar cell. The optical properties are considered, and the amount of hydrogen contained in those films is determined. The film properties are found to strongly depend on the film composition and the hydrogenation level. The number of hydrogen atoms in the films is varied by changing the gas mixture composition, and IR absorption in α-Si:H and α-G e :H films is measured. The α-Si:H and а-Si 0,88 Ge 1,2 :H films were used to fabricate three-layer solar with an element area of 1,3 sm 2 and an efficiency (η) of 9.5 %.

The Erroneous Banishment of Plastics Authorized by Walter Eevers Since some months, youth is marching in the streets of several cities throughout Europe. They scream for political attention for the fight against climate change. The debates in the press and on social media go into all directions and give attention to technological solutions to fight climate change, the need for personal lifestyle adaptation but also to fights against nuclear power generation, air traffic etc. But in the margin of these protests also plastics and the use of plastics are condemned in many of these communications.
