1. 16. Institutional arrangements and competitive posture : effects of company structures in the commercial printing industry

   Författare :Thomas Mejtoft; Nils Enlund; Robert G. Picard; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; business strategy; cooperation; customer value; institutional arrangements; printing industry; vertical integration; Industrial organisation; administration and economics; Industriell organisation; administration och ekonomi; Media and communication studies; Medie- och kommunikationsvetenskap;

   Sammanfattning :  The research objective of this dissertation is to investigate the impact of institutional arrangements, with respect to vertical integration and cooperation, on competitive advantages within the commercial printing industry, with specific focus on digital printing. This dissertation comprises six research papers, based on four qualitative case studies and a quantitative survey study, all carried out in Sweden in the years 2004-2008. LÄS MER

3. 17. Analysis of ICP pulsatility and CSF dynamics : the pulsatility curve and effects of postural changes, with implications for idiopathic normal pressure hydrocephalus

   Författare :Sara Qvarlander; Anders Eklund; Jan Malm; Richard Birgander; Martin U Schuhmann; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cerebrospinal fluid; CSF dynamics; Intracranial pressure; Pulse pressure; Normal pressure hydrocephalus; Posture; Predictive tests; Mathematical modelling; Magnetic resonance imaging; Infusion tests;

   Sammanfattning : The volume defined by the rigid cranium is shared by the brain, blood and cerebrospinal fluid (CSF). With every heartbeat the arterial blood volume briefly increases and venous blood and CSF are forced out of the cranium, leading to pulsatility in CSF flow and intracranial pressure (ICP). LÄS MER

4. 18. Middle Ear Pressure; A New Method for Continuous Direct Measurements

   Författare :Bo Tideholm; allergi och livskvalitet Laryngoesofagologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; man; physiology; sleep; posture; pressure; patulous Eustachian tube; middle ear; Ear; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

   Sammanfattning : Disturbances in the pressure homeostasis of the middle ear (ME) system cause a pressure gradient across the tympanic membrane lessen the effectiveness of sound transmission and may be associated to development of chronic ME disease. An equipment for continuous direct pressure measurements was developed and was found to be accurate, base-line stabile and portable. LÄS MER

5. 19. Ventilation distribution in the lung periphery measured by inert gas washout : influence of increased gravity, anti-G suit pressure, body posture, and breathing pattern

   Författare :Mikael Grönkvist; Göran Hedenstierna; Linköpings universitet; []
   Nyckelord :acceleration; anti-G suit; body posture; cdi; dcdi; human centrifuge; He; hypergravuty; lung; multiple-breath washout; single-breath washout; SF 6; standing; supune; trapped gas; ventilation distribution; MEDICINE; MEDICIN;

   Sammanfattning : The lung is highly sensitive to forces of gravity and acceleration, and to surrounding pressures. This thesis aimed to assess the effects on ventilation distribution in peripheral lung units when changing the direction or magnitude of the gravitational vector and when compressing the lower body half with an anti-G suit (AGS).

7. 20. Constrained Optimization for Prediction of Posture

   Författare :Erik J. Dijkstra; Elena M. Gutierrez-Farewik; Anders Eriksson; Mikael Skipper Andersen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Static optimization; Multibody system; Musculoskeletal model; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : The ability to stand still in one place is important in a variety of activities of daily living. For persons with motion disorders, orthopaedic treatment, which changes geometric or biomechanical properties, can improve the individual'sposture and walking ability. LÄS MER
