They focused on the relation between ethics and two main contexts： education and research. This paper aims at discussing what ethical procedures were taken in international studies. The data were collected at ERIC （Educational Resources Information Centre） database during the first semester of 2016. As analytical categories, we used the ethical procedures established by Brazilian Applied Linguists. The contribution is addressed to both BAL and International Applied Linguists once it offers an overview about a specific topic of research （viz., ethics）. As results, we observed that most of the topics presented by the Brazilian applied linguists were also covered by the research analyses. However, the social relevance was not reported properly by the data and that may be improved.展开更多

Solar thermal collectors, particularly all-glass evacuated tubular collectors, have been studied and developed for 30 years, and solar thermal industry has developed rapidly for 15 years. There are various solar thermal systems, with an operation area of around 108 million m2 in 2007. These systems mainly provide domestic hot water, but some other applications are under extensive study and development as well.展开更多

Systematic characterization and comparative analysis of root architec- ture were conducted to evaluate the relationship between root architecture and P efficiency and its possible evolution- ary pattern. Our results found that: i) root architecture was closely related to P efficiency in soybean. Shallow root archi- tecture had better spatial configuration in the P-rich culti- vated soil layer hence higher P efficiency and soybean yield; ii) there was a possible co-evolutionary pattern among shoot type, root architecture and P efficiency. The bush cultivated soybean had a shallow root architecture and high P efficiency, the climbing wild soybean had a deep root architecture and low P efficiency, while the root architecture and P efficiency of semi-wild soybean were intermediate between cultivated and wild soybean; iii) P availability regulated root architec- ture. Soybean roots became shallower with P addition to the topsoil, indicating that the co-evolutionary relationship be- tween root architecture and P efficiency might be attributed to the long-term effects of topsoil fertilization. Our results could provide important theoretical basis for improving soy- bean root traits and P efficiency.展开更多
