Use of Geophysical Techniques for the Localization of the Restricting Zones of Permeability in the Bottom of Basin： Forecasting the Zones of Clogging

Measurements of dielectric parameters followed by permeability tests are performed on soil samples of infiltration basin. The dielectric parameters are obtained by TDR （time domain reflectrometry） measurements from which it is found that the measurement of the permittivity, the electrical conductivity and the relaxation time of compacted soil allows the mapping of the values of the coefficient of permeability at the surface of an infiltration basin. With the distribution of the coefficient of permeability, the areas of water stagnation can be detected before the basin filling. The study proves that the TDR measurements for the detection of these zones can be used for the management of infiltration basins for sustainable working and their remediation can be undertaken before the rainy seasons.

Experimental studies of the geosynthetic anchorage – Effect of geometric parameters and efficiency of anchorages

The soil reinforcement by geosynthetic is widely used in civil engineering structures: embankments on compressible soil, slope on stable foundations, embankments on cavities and retaining structures. The stability of these structures specially depends on the efficiency of the anchors holding the geosynthetic sheets. Simple run-out and wrap around anchorages are two most commonly used approaches. In order to improve the available knowledge of the anchorage system behaviour, experimental studies were carried out. This paper focuses on a three-dimensional physical modelling of the geosynthetics behaviour for two types of anchors (simple run-out and wrap around). The pull-out tests were performed with an anchorage bench under laboratory controlled conditions with three types of geosynthetic (two geotextiles and one geogrid) and in the presence of two types of soil (gravel and sand).The results show that there is an optimum length for the upper part of the geosynthetic for the wrap around anchorage.     

Role of microorganisms in water purification of compounds of iron and manganese in a dense layer of sorbent–catalyst

The article contains assessment and contains experimental substantiation of the involvement of iron- and manganese-oxidizing microorganisms in the removal of manganese compounds from model solutions. Defined and identified are cultures of such microorganisms. The article has shown the efficiency of removing manganese compounds by the layer of a sorbent–catalyst under conditions of changing the temperature conditions for a long time.

Identification of key competences of design‐builders in the construction market of the People’s Republic of China (PRC)

Design‐builders play a vital role in the success of DB projects. In the construction market of the People’s Republic of China, most of the design‐builders, however, lack adequate competences to conduct the DB projects successfully. The objective of this study is, therefore, to identify the key competences that design‐builders should possess to not only ensure the success of DB projects but also acquire the competitive advantages in the DB market. Five semi‐structured face‐to‐face interviews and two rounds of Delphi questionnaire survey were conducted to identify the key competences of design‐builders. Rankings have been assigned to these key competences on the basis of their relative importance. Six ranked key competences of design‐builders have been identified, namely: (1) experience with similar DB projects; (2) capability of corporate management; (3) combination of building techniques and design expertise; (4) financial capability for DB projects; (5) enterprise qualification and scale; and (6) credit records and reputation in the industry. The design‐builders can make use of the research findings as guidelines to improve their DB competence. These research findings will also be useful to clients during the selection of design‐builders.

Modelling of emission of volatile organic compounds from building materials—estimation of gas-phase mass transfer coefficient

A mathematical model is developed to predict Volatile Organic Compound (VOC) emission rates from homogeneous materials. The model considers both mass diffusion and mass convection processes in the boundary layer between the material surface and the air flow. Establishing the relationship between the surface air flow and emission rate; the model, therefore can predict the material emission rate under different environmental conditions. The other feature of the model is that all the parameters have clear physical meaning and can be either found in literature or calculated using known theories and/or equations.The prediction of the mathematical model was validated at three different levels; with experimental results from the CBS specially designed test chamber, with experimental results from the EPA which were carried out in an ASTM chamber, and finally with the predictions made by other models. The results indicate that there is, in general, good agreement between the model predictions and the experimental results. The main advantage of this model is that the model does not require any experimental data as input.     

‘Clubification’ of urban public spaces? The withdrawal or the re-definition of the role of local government in the management of public spaces

This paper reports on a case study on the forms of urban public spaces governance that are emerging in the UK out of a rearrangement of governance responsibilities between local government, communities and private interests. Based on cases of public spaces in London under a variety of different governance arrangements, the paper critiques the dominant explanations of those processes, and suggests a far more complex picture in which empowerment and disempowerment of stakeholders of various types happen at the same time, along complex lines defined by geography, strength of stake and representation of that stake in a formalized governance transfer contract. As the paper suggests, the resulting ‘localization’ of governance, the devolution of governance responsibilities to those local actors with the stronger stake in them, does not intrinsically reduce the publicness dimension of public space, but it reshapes that notion towards one with a variety of ‘publicnesses’, with their own governance dynamics and positive and negative consequences.     

‘The spring of hope,the winter of despair’: an unfinished narrative of Mediterranean cities

Early in 2011, a powerful surge of protest calling for political and social change swept along the North African shoreline. Not for the first time, and almost certainly not for the last, the established rhythms of urban life in the region were to be severely disrupted. The patient work of well-laid plans counted for little as people took to the streets and military governments resisted; overnight, public squares became places of protest and even battlegrounds. Tunis, Tripoli and Alexandria – the three cities that feature in this paper – were by no means the only places to feel the strong winds of change. Moreover, all three of the case studies have long histories and, as with so many other cities around the Mediterranean, turbulence is nothing new. It is hard to think of other parts of the world where cities have so often experienced changing fortunes: at one moment in history nourishing the growth of civilization, at another trapped in a spiral of decline. Located between three continents, in a region of geological as well as geopolitical instability, Mediterranean cities are familiar with bad times as well as good. This paper explores the nature of this volatile process and its impact on urban life and form.     

Retrospect and Prospect of the Protection and Reconstruction of Old Beijing

Beijing is a famous,cultural and ancient capital inour country and one of the first group of famous,histori-cal and cultural cities proclaimed by the State Council.The Imperial Palace,the Great Wall and the Ape—manCave are listed as the” world cultural heritage”,whichhas further confirmed Beijing’s historical position in theworld.It has always been an important task in the field ofBeijing’s overall planning to protect this historical citywell while carrying out its modernization.At present,itbecome more important to do so for Beijing when the re-form and opennng policy is accelerated,the socialist mar-ket economy is being set up and the development of thecity is speeded up.To protect and reform the old Beijing,a great dealof valuable exploration has been put into practice overthe past more than 40 years.The work is now heing putinto a more scientific course.A few points of view are asfollows:
