  1. 1. Malocclusion among adolescents : qualitative and quantitative studies of the impact on oral health and daily life

    Författare :Jari Taghavi Bayat; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Though not considered pathological conditions, malocclusions and their impact have traditionally been assessed from a professional point of view. This could be due to their multifactorial aetiology and the great variation in their severity. LÄS MER

  2. 2. A Novel Bone Conduction Implant System

    Författare :Hamidreza Taghavi; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; sound radiation; amplitude modulation; low-power systems.; bone conduction implant; feedback; bone anchored hearing aid; RF power amplifier; gain headroom; implantable transducer; wireless power and data transmission; RF power and data link;

    Sammanfattning : Bone conduction is the process by which an acoustic signal vibrates the skull bones to stimulate the cochlea. Patients with pure conductive hearing loss, mixed hearing loss, and single sided deafness are sometimes poorly rehabilitated by conventional air conduction hearing aids due to for example the functionality losses in the middle ear.

  3. 3. The Bone Conduction Implant (BCI) - Preclinical Studies, Technical Design and a Clinical Evaluation

    Författare :Hamidreza Taghavi; Chalmers University of Technology; []
    Nyckelord :Bone conduction implant; Amplitude modulation; Bone anchored hearing aid; Radio frequency power amplifier and inductive link; Long-term implantation.; Low-power systems; Implanted transducer;

    Sammanfattning : The Bone Conduction Implant (BCI) system has been developed as an alternative to the percutaneous bone anchored hearing aid (BAHA) with the advantage that the skin is kept intact. The transducer is permanently implanted and attached to the skull via a flat surface contact to the temporal bone. LÄS MER

  4. 4. Sustainable Manufacturing Strategy; Identifying Gaps in Theory and Practice

    Författare :Naghmeh Taghavi Nejad Deilami; Chalmers University of Technology; []
    Nyckelord :production competence theory; manufacturing strategy; operationalization; environmental and social sustainability;

    Sammanfattning : Since the introduction of sustainable development in 1972, an increasing number of companies have striven to create a competitive position by means of sustainability in their operations. Sustainability has become part of a firm's business strategy; therefore, strategic alignment of the manufacturing function to the business strategy's vision and goals regarding sustainability has become essential for manufacturing companies.

  5. 5. Toward the Sustainable Development of Operations: Improving Energy Efficiency as a Means to Sustainability as Practice

    Författare :Naghmeh Taghavi Nejad Deilami; Chalmers University of Technology; []
    Nyckelord :Sustainable operations management; Operations management; Operations strategy; Energy efficiency;

    Sammanfattning : Addressing the challenges of sustainable development demands companies to understand the “how” to actualize sustainability-related objectives and cultivating conditions that encourage practicing sustainability. It also demands companies to structure their operations around less costly economic processes while maintaining the efficient use of resources and standards for workers’ well-being at the operational level.
