With the rapid development of our economy, the ecology issues are becoming more and more important. In order to raise people's ecological awareness, I conducted this empirical study on the transitivity analysis of a story (Our Way of Life Is Piling Pressure on Ecosystems) from the website of the United Nations Environment Programme. By analysing and comparing the distribution and percentage of different transitivity process in this story, what we can find are:1) the main processes are material process (60.9%) and relational process (21.7%), followed by the behavioural process (8.7%), verbal process (4.3%), and existential process (4.3%); 2) most of the more-than-human beings influenced by human beings are in the passive position, and few of them are in the positive position; 3) no matter what position the more-than-human beings are in, they are always the victims of human beings' activity. Based on the above findings, this story can be regarded as a beneficial discourse, and we should promote and spread it as it can encourage people to protect environment.
The hen egg shells (HES) from EnShi, HuBei Province, China, which contain selenium, are used as adsorbent for the adsorption of lead ion from its aqueous solutions. The selenium in the HES could help to remove lead from its aqueous solution. The HES had been found to be the more efficient in the experiment and removed about 95% of lead from its aqueous solution. The final concentration of lead ion was found lower than the waste water quality standards from the initial concentration of lead ion 100.0 mg/L through these two steps of adsorptions. One gram of the HES can adsorb nearly 31.71±0.040 mg of lead ions. The adsorption kinetics was fitted by first-order model throughout the period. The present adsorption process is spontaneous, indicating HES can be availably used for the removal of lead ions from its aqueous solution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
