Forms and Aesthetics of Bridges Feature Article

Man-Chung Tang

Engineering 2018, Volume 4, Issue 2, Pages 267-276 doi: 10.1016/j.eng.2017.12.013

Abstract:

The objective of a bridge design is to produce a safe bridge that is elegant and satisfies all functionalityA successful bridge design must be natural, simple, original, and harmonious with its surroundings.Aesthetics is not an additional consideration in the design of a bridge, but is rather an integral partof bridge design.To achieve such a task, the bridge design engineer must have a good understanding of structural theory

Control concept and countermeasures for shallow lakes' eutrophication in China

JIN Xiangcan, LU Shaoyong, HU Xiaozhen, JIANG Xia, WU Fengchang

Frontiers of Environmental Science & Engineering 2008, Volume 2, Issue 3, Pages 257-266 doi: 10.1007/s11783-008-0063-3

Abstract: Research on lake eutrophication in China began in the early 1970s, and many lakes in China are now known to be in meso-eutrophic status. Lake eutrophication has been showing a rapidly increasing trend since 2000. Investigations show that the main reasons for lake eutrophication include a fragile lake background environment, excessive nutrient loading into lakes, excessive human activities, ecological degeneration, weak environmental protection awareness, and lax lake management. Major mechanisms resulting from lake eutrophication include nutrient recycling imbalance, major changes in water chemistry (pH, oxygen, and carbon), lake ecosystem imbalance, and algal prevalence in lakes. Some concepts for controlling eutrophication should be persistently proposed, including lake catchment control, combination of pollutant source control with ecological restoration, protection of three important aspects (terrestrial ecology, lake coast zone, and submerged plant), and combination of lake management with regulation. Measures to control lake eutrophication should include pollution source control (i.e., optimize industrial structural adjustments in the lake catchment, reduce nitrogen and phosphorus emission amounts, and control endogenous pollution) and lake ecological restoration (i.e. establish a zone-lake buffer region and lakeside zone, protect regional vegetation, utilize hydrophytes in renovation technology); countermeasures for lake management should include implementing water quality management, identifying environmental and lake water goals, legislating and formulating laws and regulations to protect lakes, strengthening publicity and the education of people, increasing public awareness through participation in systems and mechanic innovations, establishing lake region management institutions, and ensuring implementation of governance and management measures.
