Due to increased grid problems caused by renewable energy systems being used realize zero buildings and communities, the importance of sharing self-sufficiency also increased. In this study, performance an energy-sharing community was investigated improve its efficiency self-sufficiency. For a case smart village selected via detailed simulation. thermal for cooling, heating, domestic hot water ...

With the urbanization process of the hot summer and cold winter (HSCW) zone in China, the energy consumption of space and water heating in urban residential buildings of the HSCW zone has increased rapidly. This study presents the energy efficiency and sustainability evaluation of various ways of space and water heating taking 10 typical cities in the HSCW zone as research cases. Two indicators...

PURPOSE The incidence of acanthamoeba keratitis (AK) in the UK is some 15 times that in the United States and seven times that in Holland. To investigate reasons for this higher frequency, a study of the role of domestic tap water as a potential source of AK was undertaken. METHODS Tap outlets from the homes of 27 patients with culture-proven AK were sampled and cultured for free-living amoeb...

The infrared spectrum of sunspots is analyzed in the H-band region (5540–6997 cm 1) with the aid of a new, hot (T 1⁄4 1800 K) laboratory emission spectrum of water covering 4878–7552 cm 1. There are 682 lines in the sunspot spectrum and 5589 lines in the laboratory spectrum assigned quantum numbers corresponding to transitions due to H2O using a combination of previously known experimental ener...

In the inner solar system, the planets' orbits evolve chaotically, driven primarily by secular chaos. Mercury has a particularly chaotic orbit and is in danger of being lost within a few billion years. Just as secular chaos is reorganizing the solar system today, so it has likely helped organize it in the past. We suggest that extrasolar planetary systems are also organized to a large extent by...

Being sustainable and producing little waste products, the renewable energy knows a rapid deployment. Unfortunately, the intermittent characteristic of these energies makes them difficult to control. The influence of this aleatory character can be reduced with the coupling of two or more sources of renewable energy and secondly with a sound management of storage systems. This new configuration ...
