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.  相似文献

A vibrant construction industry in a developing country, that mobilizes human and local material resources in the development and maintenance of buildings, housing and physical infrastructure, is an important means to promote increased local employment and accelerate economic growth. Ghana, a country of about 22 million people, currently has one of the fastest growing economies in West Africa. The Government of Ghana (GOG) has recently set a target of annual economic growth rate of 8% and above, up from annual growth rates of 5–6% in the past five years (2001–05). It intends to use the agricultural sector as the major vehicle for achieving such high growth rates in order for the country to reach the status of a middle income country by 2015. Surprisingly, the construction industry was left out from the list of major growth drivers of the economy. We contend that with the construction industry currently making up the third largest sector of the economy, special attention should be given to this industry as one of the main drivers of economic growth in Ghana. Therefore we conducted a study to analyse the causality links between the growth in the construction industry and the growth in the macro‐economy of Ghana, measured by the gross domestic product (GDP), to ascertain whether the construction industry can be used to lead the entire economy on a growth path. The analysis was based on a simple Granger causality test using time series data from 1968 to 2004. We showed that growth in the construction industry Granger‐caused growth in GDP, with a three‐year lag. The construction industry needs to be considered as one of the major drivers of economic growth in Ghana.  相似文献

By analyzing data from the 2006/07 and 2013 French census as well as data extracted from the Yellow Pages, this paper seeks to understand how the French city of Arles is preparing for the arrival of Frank O. Gehry’s Luma Foundation landmark building in 2019, and how a big-scale construction site, still devoid of its future aesthetics and cultural function, impacts the urban core. To do this, we consider three hypotheses: (1) The Rise of New Audiences: a landmark building attracts the new populations to the pre-existing urban cultural core, (2) Residential Pattern: a landmark building induces social transformation of surrounding neighborhoods, (3) Mobility: a landmark building induces the arrival of the “most talented and educated” people. After testing these hypotheses with cartographical and statistical methods, our findings demonstrate strong support for Mobility, and mixed support for The Rise of New Audiences and Residential Pattern. Even though the causal links between the landmark building and new urban dynamics are difficult to prove, our results reveal that Arles is “customizing” itself to the forthcoming cultural and aesthetic dimensions of the Luma Foundation.  相似文献

The interaction of several trace elements (Cd, Zn, Cu, Pb, As, Bi, and Tl) was studied by leaching experiments in agricultural soils affected by the Aznalcóllar toxic spill. The spill led to contamination by acid waste waters and sludge deposition. The levels of contamination recorded after the sludge was removed from soils showed that highly contaminated areas remained. A comparison of soils directly affected by sludge deposition and acid waste waters with soils contaminated only by acid waste waters demonstrated that Zn/As and Cd/As ratios were good indicators of the two contributions to the contamination. Soil samples were characterised and grouped according to their texture and carbonate content. The response of elements to single extractions with CaCl2 0.01 mol l-1, CaCl2 1 mol l-1, CH3COOH 0.43 mol l-1, and EDTA 0.05 mol l-1 enabled us to estimate their mobility in the soils. Cd and Zn were found to be the most mobile elements. Cu showed an intermediate mobility, especially in an acidic medium. Pb, As, Bi and Tl were found to be non-mobile elements. A comparison of referent, low and highly contaminated samples showed that the presence of sludge had an effect on desorption yields, in part due to the short-term after the contamination. Calculations of a relative scale of long-term mobility, between soils and trace elements, provided further conclusions derived from the use of single extractions.  相似文献

During the 1960s, many changes reshaped the economy, the society and the arts. The Cold War, the Space Race, the construction of a new middle class in most western societies led by the postwar economic prosperity with unprecedented urban growth followed by severe environmental problems fostered the design of spectacular urban utopian cities and mega-architectures. In those years, Japan was the source of highly influential bold and visionary urban and architectural ideas which relied on advanced technology. These ideas were conceived on the thought that cities could be seen as gigantic but impermanent entities able to transform itself according to an organic process of adaptation of its elementary components. This paper briefly revisits and critically discusses the legacy of the iconic mega-strnctural projects of Japanese Metabolist Movement and other visionary architects and planners of the 1960s, such as Paolo Soleri, Buckminster Fuller, Archigram. It attempts to enlighten the continuity with contemporary innovative and experimental urban models and ideas for the society and the city of the future, such as the Smart Cities, Eco-Cities, Green Urbanism, whose design is led by concerns related to climate change, the necessity of energy efficiency, the improvement of urban landscape and the valorization of depleted natural resources.  相似文献

To comprehend the development of the famous histori-cal and cultural cities in China and their conservation plan-ning, it is necessary to understand, first of all, the back-ground of their history and present condition. This back-ground has taken shape in the historic development of thecities and is influenced by many complicated factors of thepresent time. To discuss these factors in simple way, theycan be summarized as follows:The impact of the historical and cultural ideas;The impact of the physical and environmental condi-tion;The impact of the present socialand economicsituation.The impact of the historical and cultural ideasChina is a country with ancient civilization. TheChinese cultural has been shaped through development, in-heritance and harmony in a history of 5000 years on the ba-sis of the ancient Huaxia Culture with the Yellow River andthe Yangtse River as the main arteries.The rising of ancient cities in China can be traced backto over 3500 years ago. China is a multinational country. Int  相似文献

The idea of ‘reconstruction’ is now well established in the historiography of South African planning. Particular attention has been paid to ‘reconstructionist planning’: during and immediately after World War; in the apartheid era; and, in the recent context of post-apartheid development. The centenary celebrations of the Anglo-Boer South African War (1899–1902) are, however, directing attention to the programme for the reconstruction of the previous Boer republics that was initiated by the imperialist proconsul, Lord Milner, and is the subject of ongoing controversy. Natal was not a direct target of Milner's programme but the aftermath of conflict in this British colony was linked to important socio-economic and spatial transformations. The idea of ‘town planning’ was only in an embryonic form at the time but ‘post-war reconstruction’ in Natal included interventions in the shaping of urban and rural space that provided the basis for future programmes of reconstruction and planning, including that of racial ordering under apartheid. For example, the system that developed in Durban to finance the construction and administration of segregated municipal housing for Africans was later exported to the rest of South Africa and became a major feature of the National Party's programme of ‘township development’.  相似文献

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.  相似文献
