After three decades of housing reform in China, housing assets constitute a sizable share of family wealth but are distributed unevenly, as registered homeowners are predominantly male. This is partly because males generally have higher incomes than females and can therefore contribute more to the financing, but also because males receive more...

The realisation of an urban design involves many players, such as designers, critics, politicians, journalists, public relations specialists and residents. In order to consult with each other they make use of drawings, but also frequently of words, to be able to interpret the drawn objects in the plans. But are these urbanistic notions used by...

According to basic economics, when vacancy rates rise, house prices should decrease and vice versa, responding to supply and demand mechanisms. However, previous studies have observed that, before the economic crisis, this was not the case in Spain and Malta. It has been questioned whether this paradox is a Mediterranean phenomenon or simply the...

Target 6.4 of the recently adopted Sustainable Development Goals (SDGs) deals with the reduction of water scarcity. To monitor progress towards this target, two indicators are used: Indicator 6.4.1 measuring water use efficiency and 6.4.2 measuring the level of water stress (WS). This paper aims to identify whether the currently proposed...

Under apartheid, black African households could not own land or homes in most
major urban centres in South Africa. This limited residential mobility and locked many households into state rental accommodation in townships. Homeownership for all South Africans was restored in the mid-1980 s and the Group Areas Act was repealed in 1991.

This work reports the analysis of the time-resolved photoluminescence behaviour on the nanosecond and microsecond time scale of fourteen historical and contemporary titanium white pigments. The pigments were produced with different production methods and post-production treatments, giving rise to a remarkable variability of titanium dioxide...

The aim of this research was to study the biological feasibility of the Partial Nitritation/Anammox (PN/A) technology to remove nitrogen from municipal mainstream wastewaters. During stable process operations at summer temperatures (23.2 ± 1.3°C), the total nitrogen removal rate was 0.223 ± 0.029 kg N (m3 d)−1 while at...

Bird strikes have the potential to cause severe damage to aircraft. Therefore, measures to reduce the risk of bird strikes are performed at airports. However, this risk is not limited to the airport but is increased in the arrival and departure corridors as well. Consequently, a significant amount of bird strikes occurs outside the direct...

Aircraft mass is a crucial piece of information for studies on aircraft performance, trajectory prediction, and many other topics of aircraft traffic management. However, It is a common challenge for researchers, as well as air traffic control, to access this proprietary information. Previously, several studies have proposed methods to estimate...

Currently wastewater treatment plants (WWTP) consume a lot of energy and surface area. While the incoming water contains chemical energy (BOD) and reusable resources which are not effectively utilized. The ideal is to develop a treatment scheme which allows for the efficient removal of pollutants while minimizing the energy input and maximizing...

The implementation of autotrophic nitrogen removal in the mainstream of a municipal wastewater treatment plant is currently pursued. Among the crucial unknown factors are the kinetic properties of anaerobic ammonium oxidising (anammox) bacteria at low temperatures. In this study we investigated the adaptation of a fast-growing anammox culture...

This paper explains the development of the urban housing system in China from 1949 to 2011 with an emphasis on the factors driving housing inequality in each policy period. We argue that the logic underpinning the housing policy had shifted from socialist redistribution to the stimulation of growth in the process of market economy reform and has...

Wind is an important parameter in many air traffic management researches, as it often introduces significant uncertainties in aircraft performance studies and trajectory predictions. Obtaining accurate wind field information has always been a challenge due to the availability of weather sensors. Traditionally, there is no direct method to...

Open access to flight data from ADS-B (Automatic Dependent Surveillance Broadcast) has provided researchers more insights for air traffic management than aircraft tracking alone. With large quantities of trajectory data collected from a wide range of different aircraft types, it is possible to extract accurate aircraft performance parameters....
