AbstractIntragranular ferrite (IGF), which nucleates from specific inclusion surfaces in low alloy steels, is the desired microstructure to improve mechanical properties of steel such as the toughness. This microstructure is especially important in the coarse grain heat affected zone (CGHAZ) of weldments. The latest review paper focusing on the role of non-metallic inclusions in the IGF formation in steels has been reported by Sarma et al. in 2009 (ISIJ int., 49(2009), 1063–1074). In recent years, large amount of papers have been presented to investigate different issues of this topic. This paper mainly highlights the frontiers of experimental and theoretical investigations on the effects of inclusion characteristics, such as the composition, size distribution and number density, on the IGF formation in low carbon low-alloyed steels, undertaken by the group of Applied Process Metallurgy, KTH Royal Institute of Technology. Related results reported in previous studies are also introduced. Also, plausible future work regarding various items of IGF formation is mentioned in each section. This work aims to give a better control of improving the steel quality during casting and in the heat affected zone (HAZ) of weldment, according to the concept of oxide metallurgy.

Roof Greening

Under the circumstances of the increasing energy consumption of buildings, the development and application of building energy efficiency technology have attracted the attention of many people. As one of the important building energy efficiency technologies, roof greening has played a positive role in building a low-carbon and energy-saving society. This paper analyzes the technological characteristics and the formation methods of the roof greening system. It also expounds on the role of roof greening in building energy conservation.

The Relationship

Abstract In this paper, we examine the role of mobility-related attitudes in the travel mode use of young people, the extent to which young adults and teenagers behave consistently in relation to their attitudes, and the conditions on which the consistency of attitudes and behaviour depends. We thus continue the current discussion about the loss of importance of the car for young people in which various socio-demographic trends, but also changed attitudes, are used as explanatory factors, especially on a hypothetical level. Our contribution closes a research gap in that so far neither the relationship between attitudes and behaviour among young people has been empirically investigated nor has this relationship been empirically placed in a context of spatial, economic and socio-demographic conditions. We address this by means of differentiated correlation analyses and the calculation of correlation differences on the basis of a nationwide German survey of young people from 2013. This enables us to demonstrate that young people basically behave consistently in line with their attitudes. However, there are significant differences which confirm that certain spatial, economic and socio-demographic conditions are essential for the implementation of attitudes into corresponding travel mode use.

Role Of The State

Since the crisis of the real economy in 2008, an intense discussion about the need for changes in the economy, supported by a number of declarations on the global scale, has been developed. The analysis of the causes and effects of the economic downturn and the challenges of the future have had a huge impact on this state of affairs. As a result, some states have taken action to remedy the situation. Many of them were aimed at structural changes in production, consumption and environmentally friendly investment. At the same time, the concept of "low carbon economy" and "green economy" gained importance. The aim of this paper is to present the role of the state in the economy in terms of creating conditions for a green economy. The thesis of the publication is: implementation of structural changes related with creating a green economy requires involvement of the state.
