1. Presence through actions : theories, concepts, and implementations
Abstract : During face-to-face meetings, humans use multimodal information, including verbal information, visual information, body language, facial expressions, and other non-verbal gestures. In contrast, during computer-mediated-communication (CMC), humans rely either on mono-modal information such as text-only, voice-only, or video-only or on bi-modal information by using audiovisual modalities such as video teleconferencing.

2. Cardiovascular and respiratory effects of apnea in humans
Abstract : This thesis deals with cardiovascular and respiratory effects of apneas in humans. During apnea (breath-holding), a number of interacting cardiovascular reflexes are initiated, and together these reflexes are called the “diving response”. READ MORE

3. Autonomic cardiac control in long QT syndrome : clinical studies of arrhythmogenic triggers
Abstract : Background: Long QT syndrome (LQTS) is an inherited cardiac disease characterized by prolonged cardiac repolarization and an increased risk for life-threatening arrhythmias. These arrhythmias are typically triggered by adrenergic stimuli, such as physical activity and intense emotions, implicating that the sympathetic part of the autonomic nervous system (ANS) is involved in arrhythmogenesis.

4. Cardiovascular and hematological responses to voluntary apnea in humans
Abstract : This thesis deals with cardiovascular and hematological responses to voluntary apnea in humans, with a special focus on O2 usage and storage. Humans, and many other air‐breathing animals, respond to apnea (breath holding) with a collection of interacting cardiovascular reflexes, which are collectively called the diving response. READ MORE

5. The human diving response : effects of temperature and training
Abstract : The aim was to elucidate the cardiovascular response associated with breath-hold diving, especially the effects of temperature in its elicitation and the effects of different types of training on the human diving response (DR) and breath-holding time (BHT), and to evaluate the human DR in a mammalian perspective. A model for simulated diving by apnea and facial immersion in cold water was developed. READ MORE
