1. Adapting Variable Air Volume (VAV) Systems for Office Buildings without Active Control Dampers
Sammanfattning : In commercial buildings the building services systems may account for a substantial part of the need of energy. There is, at least in Sweden, a large existing stock of 20 to 30 year old office buildings, which are supplied with centralised constant air volume flow (CAV) air conditioning systems with the primary function to keep the room temperature at an acceptable level summertime.

2. Shb and Its Homologues: Signaling in T Lymphocytes and Fibroblasts
Sammanfattning : Stimulation of the T cell receptor (TCR) induces tyrosine phosphorylation of numerous intracellular proteins, leading to activation of the interleukin-2 (IL-2) gene in T lymphocytes. Shb is a ubiquitously expressed adapter protein, with the ability to associate with the T cell receptor and several signaling proteins in T cells, including: the TCR ζ-chain, LAT, PLC-γ1, Vav, SLP-76 and Gads.

3. Air - for Health and Comfort, An Analysis of HVAC Systems' Performance in Theory and Practice
Sammanfattning : One part of the objective is to analyze how different ventilation systems perform in practice when it comes to supplying and exhausting designed air flow in different outdoor and indoor conditions. The other part is to analyze the design criterias and the energy use of a variable air volume system based on controlled static pressure at the branch duct level and supplying outdoor air only.

4. Ventilation System Design - A Fluid Dynamical Study with Focus on Demand Control
Sammanfattning : Ventilation corresponds to a large part of the total energy use of a building and a lot of attention has been paid to how to reduce this energy use. However, much of this work on saving energy has been focused on reduction of the airflows and how this in turn reduces the energy use. LÄS MER
5. Measurements and Analyses of the Performancs of Laboratory Fume Hoods
Sammanfattning : When working with health-hazardous substances or unpleasant airborne pollutants, it is important to have ventilation systems that are designed and operated to protect persons working in the laboratory. In laboratory applications, the fume hood is the most commonly used item of protective equipment. LÄS MER
