Surface water quality models can be useful tools to simulate and predict the levels, distributions, and risks of chemical pollutants in a given water body. The modeling results from these models under different pollution scenarios are very important components of environmental impact assessment and can provide a basis and technique support for environmental management agencies to make right decisions. Whether the model results are right or not can impact the reasonability and scientificity of the authorized construct projects and the availability of pollution control measures. We reviewed the development of surface water quality models at three stages and analyzed the suitability, precisions, and methods among different models. Standardization of water quality models can help environmental management agencies guarantee the consistency in application of water quality models for regulatory purposes. We concluded the status of standardization of these models in developed countries and put forward available measures for the standardization of these surface water quality models, especially in developing countries.

The purpose of the present paper is to present some sustainable solutions for urban logistics. The approach is to identify the present challenges for urban logistics caused by the increase of freight volumes due to the development of e-commerce. To meet them, companies' sustainable practices were analyzed and the utilization of new electric power train technologies seem to offer interesting results for reducing carbon emission impacts. Using methods of literature review and experiences from ongoing electric mobile research projects, this paper argues that electric vehicles in urban distribution are a yet underestimated element towards more efficient transport processes-hence economic advantages for companies, towards the reduction of a company's footprint and even towards an increased service level for the customers.

Angle-resolved photoemission spectroscopy (ARPES) has played an important role in determining the band structure and the superconducting gap structure of iron-based superconductors. Here from the ARPES perspective, we briefly review the main results from our group in the recent years on the iron-based superconductors and their parent compounds, and depict our current understanding on the antiferromagnetism and superconductivity in these materials.
