1. Low-temperature District Heating : Various Aspects of Fourth-generation Systems
Sammanfattning : With decreasing heat demand and less availability of high-temperature heat supply in future energy systems, the current district heating systems may experience increased competition on the heat market. A viable option to mitigate increasing competition is to operate systems with lower temperature levels, and the most conceivable way to achieve lower temperature levels is to decrease return temperatures.

2. Regional oxygenation in cardiac surgery. Influence of temperature, pump flow and insulin
Sammanfattning : Surgical trauma triggers neural, endocrine and inflammatory reactions with subsequent alterations in systemic and regional blood flow, blood pressure and metabolism. These changes are detectable after all major surgical procedures but are often more pronounced after cardiac surgery, probably because of blood exposure to artificial surfaces of the heart lung machine, temperature modulation (e.

3. Dynamically predicted shelf-life service : Exploring and evaluating a potential sustainable food supply chain innovation
Sammanfattning : Roughly one third of all the food produced worldwide goes to waste. The global goals for sustainable development set by the United Nations in 2015 call for a 50% reduction of food waste per capita by 2030. We thus face several major food waste challenges that need academic and practical attention. LÄS MER
4. Low-Temperature Baseboard Heaters in Built Environments
Sammanfattning : The European Union has adopted a plan to decrease 20 % of total energy consumption through improved energy efficiency by 2020. One way of achieving this challenging goal may be to use efficient water-based heating systems supplied by heat pumps or othersustainable systems. LÄS MER
5. Thermal Modelling of Water-Based Floor Heating Systems - supply temperature optimisation and self-regulating effects
Sammanfattning : Low temperature water-based concrete embedded floor heating systems are studied. The utilisation of low quality heat sources is facilitated by low temperature heating. Theoretical models which describe the transient thermal floor heating operation constitute the basis for the analysis. LÄS MER
