    • The family with the elderly and the home help workers’ team constitute two organisations, which meet in the care work. In this context the family is extended and often constitute not only members from the nuclear family but also other members of the network of relatives, whom take part in the care of the elderly. The extended family may in some cases include four generations (Finch & Mason, 1993). Home-help for elderly people have expanded in Sweden during the period 1960 - 1980. This was due partly upon the prevailing ideology that it is important for frail elderly to stay in their own homes. Due to this expansion the local communities have developed their public home-care organisations. Different kinds of autonomous group organisation predominate (Olsson et al, 1995). Small work groups take responsibility for home help service in local areas. Home-helpers organise their job themselves, exchange experiences and give each other emotional support. In Sweden both home care and institutional care of the elderly has decreased during the 1980th and 1990th in spite of the fact that the proportion elderly over 80 years (4,5 % of the total population) has increased 60 % since 1980. Twenty-two per cent of the women and 16 % of the men over 80 were cared for in their own home 1996. This development is said to have caused relatives to care for their frail elderly in the homes side by side by the home help services in an increasing degree (Johansson, 1991; Szebehely, 1998). Public care and service has an important impact on the interaction pattern between family members (Hendriksen, 1989; Johansson, 1999; Bass m fl, 1999). Home care may serve as an intervention that influences the health, well-being and life quality of the elderly and other family members. This intervention may have positive as well as negative effects. Problems and conflicts may arise in the interaction between the family members and between the family and the public help services (see McGoldrick & Gerson, 1989). We need more knowledge about these processes. In a research project1 the family and the home help services are studied as two organisations, which interact in the care of the elderly. We start with the hypothesis that the relation between the parties will have an impact on the character and quality of the care. We also think that the quality of the interaction will have an impact on the health and wellbeing of the elderly (see Olsson, 1991, 1998; Olsson & Ingvad, 1999).

  • HCCI Operation of a Multi-Cylinder Engine
  • 2001
  • Ingår i: First Biennial Meeting of the Scandinavian-Nordic Section of the Combustion Institute. ; , s. 109-114
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • A six-cylinder truck-size engine has been converted for Homogeneous Charge Compression Ignition (HCCI) operation. This work demonstrates that it is possible to run a multi-cylinder engine under HCCI operation. The ultra-low NOX characteristic of HCCI is also demonstrated. The sensitivity of combustion timing with respect to operating parameters is investigated, and a closed-loop control system is designed which utilizes the mixing ratio of two different fuels to control the timing of combustion. The performance of the control system is evaluated experimentally.
