IMPROVED SUPPLY OF DISTRICT HEAT TO HYDRONIC SPACE HEATING SYSTEMS

The studies presented in this thesis concern hydronic space heating systems connected via heat exchangers to a district heating network: referred to as an indirect connection. The objective has been to improve the reliability of district heat supplies and to lower the return temperature from consumer substations. Two of the disadvantages of an indirect connection have been addressed: the thermodyn

Gamow -Teller Beta Decay in Drip Line Nuclei

Before radioactive ion beams became available, the Gamow-Teller (GT) giant resonance was studied using charge-exchange reactions such as (p,n) and (He,t). In beta-stable nuclei, which can be used as targets, the GT giant resonance lies above the ground state of the mother nucleus. In this thesis the GT strength distribution is studied for deformed proton drip line nuclei with 28 < Z < 72. For thes

Dysfunction between policy and industry

There are many market and organisational barriers to the breakthrough of a new industrial field such as bioenergy. For many observers, recent high prices of oil and the significant policy support measures throughout Europe, would appear to have created economic conditions that should be sufficient for the industry to prosper. However, a significant number of policies supposed to expand bioenergy (

The Dispersion of Eye Movements During Visual Imagery is Related to Individual Differences in Spatial Imagery Ability

This study explored individual differences in eye movements during visual imagery. Eye movements were recorded for participants who recalled a picture from memory while looking at a blank screen. All participants were tested for working memory capacity and the OSIVQ (Blazhenkova & Kozhevnikov, 2009) was used as an assessment for individual differences in object imagery, spatial imagery and ver
