Policymakers pay much attention to effectively increasing frequency of people's cycling in the context developing sustainable and green cities. Investigating associations environmental characteristics behaviour could offer implications for changing urban infrastructure aiming at encouraging active travel. However, earlier examinations between travel are limited by low spatial granularity coverage traditional data. Crowdsourced geographic information offers an opportunity determine...

There have been wide ranging and ongoing debates regarding the relative advantages disadvantages of high-density development for context social sustainability. However, little this discussion has focused on small-scale (HDSS), which emerged as typical urban form in many large Chinese cities. This paper examines processes that shape HDSS neighbourhood subsequent consequences development. Document analysis interview methods were used a case study city Shenzhen. Revealing trade-offs behind...

The information of land use plays an important role in urban planning and optimizing the allocation resources. However, traditional classification is imprecise. For instance, type commercial highly filled with categories shopping, eating, etc. number mixed-use lands increasingly growing nowadays, these sometimes are too mixed to be well investigated by conventional approaches such as remote sensing technology. To address this issue, we used a new social approach classify according human...

China is one of the countries that have entered stage population aging. At present, phenomenon aging has become a widespread concern whole society. Scientific and accurate prediction will help relevant departments to formulate specific countermeasures. This paper uses Yearbook China’s 1% sampling survey in 2015 data published by National Bureau statistics. Based on basic formula, formula established using index extrapolation method predict development trend provinces cities from 2020 2050....

This study prepared sulfonated Camellia oleifera shell biochar using agricultural waste as a carbon source, and evaluated its performance catalyst for preparing biodiesel. The obtained from carbonizing shells at 500 °C 2 h serves the skeleton, then is with chlorosulfonic acid. sulfonic acid groups are mainly grafted onto surface of through covalent bonding to obtain type catalysts. catalysts were characterized by Scanning Electron Microscope (SEM), X-ray diffraction (XRD), Nitrogen...

Primate species have been increasingly threatened by legal and illegal trade in China, mainly for biomedical research or as pets traditional medicine, yet most reports on from China regard international trade. To assess a proxy amount of national primate trades, we quantified the number native featuring unique web news 2000 to 2017, including accuracy their identification, location where they were confiscated rescued, condition upon rescue. measure temporal trends across these categories,...

The COVID-19 outbreak has brought great challenges to healthcare resources around the world. Patients with exhibit a broad spectrum of clinical characteristics. In this study, Factor Analysis Mixed Data (FAMD)-based cluster analysis was applied demographic information, laboratory indicators at time admission, and symptoms presented before admission. Three clusters distinct features were identified by FAMD-based analysis. results indicated that roughly consistent findings patients....

The purpose of this paper is to explore the framework community social sustainability for China. gives a brief introduction concept and its core inclusions in literatures at beginning. Social sustainability, nevertheless, has not only been tested theoretical research debates, but also already practiced traced western context. key ideas systems are summarized after reviewing analysing concerns countries like US, UK Canada by several case studies. Furthermore, comparing evolution China,...

In the present study, an acid catalyst (UiO-66-SO3H) with Brønsted and Lewis sites was synthesised for preparation of highly efficient biodiesel from oleic methanol using chlorosulphonic sulfonated metal–organic frameworks (UiO-66) prepared acetic as a moderator. The catalysts were characterised XRD, SEM, FT-IR BET. catalytic efficiency significantly improved successful sulfonation demonstrated by characterisation techniques. Biodiesel one-pot method 85.0% yield achieved under optimum...

Nowadays, urban space has become more fragmented and largely consists of many unconnected enclaves. The significance neighborhood amenities to resident’s quality life been identified in the recent literature. However, studies have inadequately explored real experience residents their use under gated form. Since 1990s environment Chinese cities re-shaped by large creation neighborhoods. Based on a case study city Shenzhen, this paper draws upon evidence residential satisfaction with local...

In this study, we proposed a multi-source approach for mapping local-scale population density of England. Specifically, mapped both the working and daytime densities by integrating data such as residential density, point-of-interest category mix, nighttime light intensity. It is demonstrated that combining remote sensing social provides plausible way to map annual or densities. paper, trained models with England-wide subsequently tested these Wales-wide data. addition, further at higher...

Abstract This paper is an attempt to rethink the concept of ‘cultural heritage’ in general and ‘living particular as applied by conservation community, for example International Centre Study Preservation Restoration Cultural Property ( http://www.iccrom.org/priority‐areas/living‐heritage/ ).The arguments are informed my investigation into reconstruction heritage village Taoping, damaged 2008 Sichuan earthquake. In reviewing evolution theories conceptualizing its conservation, inherent links...

Cold cathode fluorescent lamps (CCFLs), with mercury as their essential component, were widely used backlight in liquid crystal display (LCD) appliances before 2008. Since 2008, the mercury-free light emitting diode started to be a substitute for CCFLs and replacement finished about 2014. Nowadays, are obsolete products from viewpoint of manufacture but they important waste. In recent years, large amounts flowing waste phase treatment this has become major issue most countries. To better...

Vibration caused by ultrasonic waves can change the structure of cell membrane and enhance its permeation. In last decade, a new ultrasound-aided method, sonoporation, has been proposed utilized to transmit target molecules (such as drugs DNA) into cells for therapy. The objective this study was investigate method loading nanometer-sized superparamagnetic iron oxide particles Sarcoma 180 sonoporation without chemical agents. SPIO nanoparticles were prepared in our laboratory means classical...

Public availability of geo-coded or geo-referenced road collisions (crashes) makes it possible to perform geovisualisation and spatio-temporal analysis across a city. This study aims detect clusters Greater London between 2010 2014. We implemented fast Bayesian model-based cluster detection method with no covariates after adjusting for potential respectively. As empirical evidence on the association street connectivity measures occurrence had been found, we selected as in our detection....

Facility location selection plays a critical role in the planning of logistics networks. It selects addresses facility nodes from candidate set locations to optimise multiple targets such as transportation efficiency and economic cost considering practical constraints real world. Thus, it is often formulated combinational optimisation problem, which solved by either mixed integer programing algorithms or heuristic methods. However, these approaches are limited several issues high...

This paper proposed and introduced an innovative concept of step-like server placement in data centers (DCs), replacing the traditional servers placed on same vertical plane with placement. The studied simplified DC model was established based actual operating DC. feasibility reliability validated by on-site experimental results. is analyzed two scenarios: effects horizontal spacings (0, 0.01, 0.02, 0.03, 0.04 m) between adjacent effect different supply air temperatures (SATs) (22.5, 23,...
