background: radon and its daughters are amongst the most important sources of natural exposure in the world. soil is one of the significant sources of radon/thoron due to both radium and thorium so that the emanated thoron from it may cause increased uncertainties in radon measurements. recently, a diffusion chamber has been designed and optimized for passive discriminative measurements of rado...

background: separate radon and thoron measurements in soil are very important in assessment of internal exposure due to inhalation of such radioactive gases. materials and methods: in this study, a low cost, small size, passive diffusion chamber has been developed for simple measurement of radon-222 and radon-220(thoron) gases separately in soil. the diffusion chamber consists of two films and ...

The Yangtze River Delta is a relatively developed area with many detached houses in the suburbs. Such are usually 1–3 stories high, mostly self-built by local people. Due to lack of passive design guidance and construction process, these houses’ energy consumption high. At present, residents use air conditioners, fans, other electrical equipment their daily lives. This paper takes suburbs Ningb...

A previous study of passive constructions has suggested that these are much more frequent in Sesotho than in English spontaneous speech (Demuth, 1989). This has raised a number of questions regarding the possible effects of the input on the apparently earlier acquisition of passives in Sesotho. This paper explores the distribution of passives in Sesotho child-directed speech. It aims to provide...

This paper implements a Life Cycle Assessment of several low-energy/passive house buildings located in Northern Ireland. work aims (i) to assess the environmental performance and (ii) evaluate effect electricity decarbonization on dwellings’ global warming potential (GWP). Three different future mix scenarios have been used compared static scenario where current remains constant. The LCA result...

We trained Japanese macaque monkeys to use tools, an advanced cognitive function monkeys do not exhibit in the wild, and then examined their brains for signs of modification. Following tool-use training, we observed neurophysiological, molecular genetic and morphological changes within the monkey brain. Despite being 'artificially' induced, these novel behaviours and neural connectivity pattern...

This project is based on the climate characteristics of Guangxi, combined with regional traditional construction methods and vernacular materials, mainly in light passive green building technology system guided by principle less manpower more natures features, which saves early investment cost operation maintenance, further verifies effectiveness strategy after completion, providing a reference...
