To investigate the status quo of heating supply and the impact of energy saving policies in northern China, a survey was conducted on the DHSs (district heating systems) in 15 Chinese cities. The average heating energy consumption was 19.2% lower than in 2008 due to the corresponding policies...

Jet impingement has been verified as an effective method to enhance convective heat transfer. To make better use of this effect, vacuum glazed transpired solar collector with slit-like perforations is developed. In this paper, a mathematical model based on energy balance equations for the solar...

Seawater-source heat pump systems (SWHP) are recognized to be outstanding heating, cooling and water heating systems. A large number of SWHP systems have been used in residential and commercial buildings in coastal areas due to the attractive advantages of high efficiency and environmental...

A new version of the RE–EM regression tree method for longitudinal and clustered data is presented. The RE–EM tree is a methodology that combines the structure of mixed effects models for longitudinal and clustered data with the flexibility of tree-based estimation methods. The RE–EM tree...

One of the consequences of rapid economic growth and industrialization in the developing world has been deterioration in environmental conditions and air quality. While air pollution is a serious threat to health in most developing countries, environmental regulations are rare and the...

This paper examines whether nutritional disruptions experienced during the stage of fetal development impair an individual’s labor market productivity later in life. We consider intrauterine exposure to the month of Ramadan as a natural experiment that might cause shocks to the inflow of...

Natural gas has emerged as an increasingly attractive source of energy since it is highly efficient, abundant, and cleaner than any other fossil fuel. In this paper, we examine the impact of widespread adoption of natural gas as a source of fuel on infant mortality in Turkey, using variation...
