Effect of Temperature and H2S Concentration on Corrosion of X52 Pipeline Steel in Acidic Solutions Meng Liu a, Jianqiu Wangb and Wei Kec State Key Laboratory of Corrosion and Protection, Institute of Metal Research, Chinese Academy of Sciences, Shenyang, China.
Although high cost corrosion resistance alloys (CRAs) were developed to resist the H2S corrosion, mild steel is still the most cost effective material used[6].
Since there is not much experience on the corrosion of carbon steels under these severe conditions, it becomes an urgent challenge for corrosion engineers to design proper corrosion control methods.
The chemical composition of the material investigated is presented in Table 1.

Strategy for cooling green buildings Boris Bielek1, a* 1Slovak University of Technology in Bratislava, Faculty of Civil Engineering, Radlinskeho 11, 810 05 Bratislava, Slovak republic aboris.bielek@stuba.sk Keywords: Green building, cooling, natural physical phenomena, renewable energy sources, natural passive cooling systems, heat pump Abstract.
Formulating of the phase of development of the technology in architecture of the Information Age, which is represented by green building, philosophy which is based on the saving or rational utilization of energy, as well as material and water sources, has its particularity in a deeper symbiosis between ecology and energy with focus on the ecologically clean renewable energy sources and its conversion, ecologically clean materials and the tendencies to reduce greenhouse emissions, connected with the production and the exploitation of buildings.
The speed of the outdoor air flow is another key factor in determining the cooling capacity.
Cooling tube shall be made of durable resistant materials (aluminum, plastic...).
In terms of managing its construction design, the difficult part is the right choice of materials for bearing structures and waterproofing technology.

Cleavage cracks form in the work-hardening region of materials response, whereas twining is restricted to the Lüders region [31].
