- The SPARC tokamak is a critical next step towards commercial fusion energy. SPARC is designed as a high-field (B-0 = 12.2 T), compact (R-0 = 1.85 m, a = 0.57 m), superconducting, D-T tokamak with the goal of producing fusion gain Q > 2 from a magnetically confined fusion plasma for the first time. Currently under design, SPARC will continue the high-field path of the Alcator series of tokamaks, utilizing new magnets based on rare earth barium copper oxide high-temperature superconductors to achieve high performance in a compact device. The goal of Q > 2 is achievable with conservative physics assumptions (H-98,H- y2 = 0.7) and, with the nominal assumption of H-98,H- y2 = 1, SPARC is projected to attain Q approximate to 11 and P-fusion approximate to 140 MW. SPARC will therefore constitute a unique platform for burning plasma physics research with high density (< n(e)> approximate to 3 x 10(20) m(-3)), high temperature (< Te > approximate to 7 keV) and high power density (P-fusion/V-plasma approximate to 7 MWm(-3)) relevant to fusion power plants. SPARC's place in the path to commercial fusion energy, its parameters and the current status of SPARC design work are presented. This work also describes the basis for global performance projections and summarizes some of the physics analysis that is presented in greater detail in the companion articles of this collection.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The use of psychotropic drugs has been widely studied; however, few studies have focused on factors associated with psychotropic drug use among the elderly. The aim of this study was to analyze the relationship between sociodemographic variables, socioeconomic status, social network, health, and physician visits and the use of psychotropic drugs among the elderly living at home. The study area was a municipality in mideastern Sweden with a population of about 21,000 inhabitants. Data from interviews with and health assessments of noninstitutionalized people age 75 and older (N = 421) were linked to an individual-based research register of prescription drug purchases. There were no differences in psychotropic drug use between men and women or between different age groups. The multivariate analyses (LISREL) showed that mental health and physician visits were associated with psychotropic drug use. An indirect relationship was also found between psychotropic drugs and loneliness and chronic morbidity, respectively.

Pharmacists´ attitudes towards importance of compounding to their profession
- 2000
-
Ingår i: J Social and Administrative Pharmacy. - 0281-0662. ; 17:3, s. 143-150
-
Tidskriftsartikel (refereegranskat)abstract
- Results of a questionnaire mailed to a random sample of 661 Swedish pharmacists in Nov 1991. 486 usable replies were received (74% response). 85% of respondents worked for the Swedish national pharmacy corporation, of whom 75% were in community pharmacies and 20% in hospital pharmacies. 60% thought that extemporaneous compounding is an important part of the pharmacy profession. The results are discussed, and compared with attitudes to the pharmacist's role found in other countries.
