7-ray spectroscopic techniques have been applied to measure properties of excited states (E*~<2MeV) in 21~ 212Po, and 213At after populating these neutron rich (N= 128) nuclei via 1SO induced few-nucleon transfer reactions on 2~ and 2~ targets. In 212po an isomeric state is located at E*= 1,477 keV with a halflife of tl/2 = 14.7_+0.3 ns. This state is interpreted to be the 8 + yrast level which decays to the ground state via the measured 8+(121.1 keY) 6+(223.3 keV) 4+(405.1 keY) 2+(727.8 keY)0 + 7-cascade. a-decay (E~10.2MeV) of the isomer is also observed. In 21~ the time spectra for members of the 4+(297.8keV)2+(799.4keV)0 + 7-cascade show a delayed component with a halflife of tl/2 = 152_+ 13 ns which is attributed to the known 8 + yrast state at E*= 1.27MeV. For 2~3At first results on the ~,-decay of excited states are presented.
The METAPOLIS as the polycentric network of urban–rural settlement is undergoing constant transformation and urbanization processes. In particular, the associated imbalance of the shrinkage and growth of different settlement types in relative geographical proximity causes negative effects, such as urban sprawl and the divergence of urban–rural lifestyles with their related resource, land and energy consumption. Implicitly related to these developments, national and global sustainable development goals for the building sector lead to the question of how a region can be assessed without detailed research and surveys to identify critical areas with high potential for sustainable development. In this study, the TOPOI method is used. It classifies settlement units and their interconnections along the urban–rural gradient, in order to quantify and assess the land-uptake and global warming potential driven by residential developments. Applying standard planning parameters in combination with key data from a comprehensive life cycle assessment of the residential building stock, a detailed understanding of different settlement types and their associated resource and energy consumption is achieved.
With China's urbanization process, a number of medium-sized cities in the south eastern coastal areas have also entered a period of rapid development. Fastgrowing cities are facing many challenges, such as housing demand and resource depletion in connection with the rapid population growth. Building industry, which contributes to a large amount of resource use, plays an important role in climate change. Along with the updating of energy saving standards, the thermal condition of building envelopes has also been dramatically improved. Therefore, energy consumption for space heating and cooling has been significantly reduced in recent years. However, there is still a lack of research concerning the embodied energy mainly caused by material use. A benchmark of life-cycle resource use in the building sector is urgently required in practice in order to achieve a more sustainable development in China. This research took the city Qingdao as a case study and examined lifecycle resource use of typical office and residential buildings with different structures and thermal conditions. The method and result could be considered as a reference for a more complete research on a building lifecycle resource use in the future. In the end of this paper, a neighborhood in Qingdao was taken as a case study to show the application of resource use benchmark in the future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
