Development and applications of trenchless technology in China

Trenchless technology has developed for almost 10 years in China since the first symposium on trenchless technology was held in Beijing (Peking) in 1996 and the China Society for Trenchless Technology-CSTT was established in 1998. Driven by the dramatically increased demand for underground pipeline installation throughout the nation, China has made significant progress in research and development in trenchless technology in the past 10 years. For example, there are more than 200 contractors engaged in trenchless construction, using more than 2000 horizontal directional drilling machines, among which approximately 700 have been introduced in the last year, and the biggest HDD rig in the world is now in China. In addition, China has made many achievements in education, research, and new products development and has accomplished many challenging projects in terms of complexity, diameter and distance in this field. There is a huge market potential for trenchless technology in mainland China.This paper presents the latest research, education, training, marketing and technical status of trenchless technology in China, and discusses the potential market, trends and factors that will influence trenchless technology in the next decade in China.     

Cell phones for the spirits: ancestor worship and ritual economies in vietnam and its diasporas

Religion has been thriving in the Socialist Republic of Vietnam since ??i m?i, the onset of market reforms in the late 1980s. Votive paper offerings, part of spiritual and economic well-being, play a crucial role in performing religious practices in the socialist country as well as among diasporic Vietnamese. In urban Hanoi, material objects made from paper are traded in marketplaces and later burned in the streets, in temples and pagodas, in private yards and other places on special occasions in order to be transmitted to the ancestors. In the past few years, the range of votive paper offerings produced, traded, and sent to the deceased has expanded to include new forms and references to new media. Drawing on recent debates in the role of media in religion and in particular on technologies of mediation, I focus on the use of votive paper offerings in the sociocultural context of the Vietnamese spirit world. I explore how new media and media technologies are embedded in multilayered processes of mediation in Vietnam and its diasporas. Taking religious practices of burning votive paper offerings as an ethnographic example, this essay aims to contribute to ongoing debates on popular religion and the sacred life of material goods in late socialist Vietnam, on its transnational ties, and on the entanglements between religion, media and materiality.

Occurrence and risk assessment of acidic pharmaceuticals in the Yellow River, Hai River and Liao River of north China

Pharmaceuticals in the aquatic environment have received great attentions from the general and scientific community due to their potential impacts on ecological and human health. We investigated the occurrence of twelve acidic pharmaceuticals and herbicides (salicylic acid, clofibric acid, ibuprofen, gemfibrozil, fenoprofen, naproxen, ketoprofen, mefenamic acid, tolfenamic acid, diclofenac, meclofenamic acid and indomethacin) in surface waters of the Yellow River, Hai River and Liao River in north China during the wet and dry seasons and assessed the potential risks to aquatic organisms posed by these acidic compounds. Seven acidic compounds were detected in the rivers, including five non-steroidal anti-inflammatory drugs (salicylic acid, ibuprofen, diclofenac, mefenamic acid and naproxen), and two blood lipid regulators (clofibric acid and gemfibrozil). The concentrations for acidic pharmaceuticals in the Yellow River and Liao River were in most cases higher in the dry season than in the wet season, but the concentrations of acidic compounds in the Hai River were generally higher in July than in November. High concentrations of these detected compounds in the Yellow River, Hai River and Liao River were found more frequently at those sites located in metropolitan areas, lower reaches or river confluences. Only diclofenac and ibuprofen were found to have medium to high risks in the three rivers based on the calculated risk quotients.     

生态还是自然主义: 关于当代种植设计的简要回顾和一些思考

Nature is a cultural construct, and a symbolic form to our cultural landscape. It plays a critical role in the profession of Landscape Architecture, shaping both the practice in the constructed environment as well as the conception of landscape in Pedagogy. This article evaluates contemporary landscape architecture practice in the U.S. through the lens of planting design and ecological design approaches. This retrospect situates selected individuals and their practices in the field of landscape architecture in the past two decades, in parallel with the evolving ecological understanding. These individuals and their works demonstrate the changes in planting design and ecological thinking in the professional practice, and most importantly how these changes contribute to current ecological design methodologies, landscape aesthetics, and public perception of landscape. In addition, the article aims to illustrate a shifting conception of Nature over time and in different cultural context, in which different conceptions of Nature facilitate various approaches to addressing environmental issues. By situating in such context, the article hopes to provide a critical view of contemporary American landscape architecture practice and the current ecological agenda, in order to enable discussions regarding the professional practice in the future.     

Towards an ‘Integration Model’ of Planning Education Programmes in a European and International Context: The Contribution of Recent Greek Experience

The article investigates planning education programmes and attempts to re-orient them in the context of both an international ‘problematique’ in reforming planning education, and European Union directives about the creation of a common European space in higher education. First, the article reviews the international trends in changes and challenges in planning and planning education in the 21st century and proposes an ‘integration model’ of planning education programmes in a European and international context. Second, the article focuses on the development of planning studies in Greece. It presents their history and development as well as the institutional framework in which planning and planning education operate. It then analyses the Greek educational curricula in two ways: (1) a quantitative analysis classifying courses into different thematic areas and thereby, revealing the basic structure of the curricula; and (2) a qualitative analysis based on interviews with academic staff in charge of educational curricula and examining the content of courses, the adopted pedagogies and possible restrictions (e.g. human capital, institutional framework, etc.) in introducing effective planning curricula. Finally, the article proposes guidelines for re-orienting educational curricula in Greek schools of planning and draws out wider implications for planning studies in the wider European and international context.     

A study of the cycling of manganese and other elements in a seasonally anoxic lake, Rostherne Mere, U.K.

The vertical distribution of sulphate, dissolved sulphide, alkalinity, pH, total iron and manganese, Fe(II) and Mn(II) and humic substances was monitored for a year in a seasonally anoxic lake, Rostherne Mere, U.K. During summer stratification Mn(II), probably of sediment origin, accumulated in the hypolimnetic bottom waters to a concentration of 50μm. Release occurred in two stages and appeared to be related to the supply of organic material to the sediment. No ferrous iron or dissolved sulphide were detected in the water column, although they were measured in the interstitial waters of the sediment. Ferrous sulphide formation in the sediment controls the iron(II) and dissolved sulphide concentrations and so minimises the concentration gradients at the sediment-water interface. Electron acceptors other than oxygen are capable of oxidising ferrous and sulphide ions in the water column. pH and alkalinity were the only other chemical components to show appreciable variation with depth, reflecting the biological processes of photosynthesis, respiration and decomposition. Iron and humic substances simultaneously increased in the surface waters after a major flood indicating that they are both present in the solution in contact with the soils of the catchment.
