  1. 1. Presence through actions : theories, concepts, and implementations

    Författare :Muhammad Sikandar Lal Khan; Shafiq ur Réhman; Haibo Li; Jiebo Luo; Umeå universitet; []

    Sammanfattning : 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. 2. Cardiovascular and respiratory effects of apnea in humans

    Författare :Johan Andersson; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; lung volume; breath-hold diving; Apnea; breath-holding; face immersion; cold stimulation; diving response; diving reflex; circulation; bradycardia; vasoconstriction; arterial blood pressure; cardiac output; spleen; respiration; splenic contraction; alveol; Physiology; Fysiologi; Respiratory system; Andningsorganen; Animal physiology; Djurfysiologi;

    Sammanfattning : 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”. LÄS MER

  3. 3. Cardiovascular and hematological responses to voluntary apnea in humans

    Författare :Robert de Bruijn; Mittuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Organism biology; Organismbiologi;

    Sammanfattning : 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. LÄS MER

  4. 4. The human diving response : effects of temperature and training

    Sammanfattning : 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. LÄS MER
