- Integrating the plasma core performance with an edge and scrape-off layer (SOL) that leads to tolerable heat and particle loads on the wall is a major challenge. The new European medium size tokamak task force (EU-MST) coordinates research on ASDEX Upgrade (AUG), MAST and TCV. This multi-machine approach within EU-MST, covering a wide parameter range, is instrumental to progress in the field, as ITER and DEMO core/pedestal and SOL parameters are not achievable simultaneously in present day devices. A two prong approach is adopted. On the one hand, scenarios with tolerable transient heat and particle loads, including active edge localised mode (ELM) control are developed. On the other hand, divertor solutions including advanced magnetic configurations are studied. Considerable progress has been made on both approaches, in particular in the fields of: ELM control with resonant magnetic perturbations (RMP), small ELM regimes, detachment onset and control, as well as filamentary scrape-off-layer transport. For example full ELM suppression has now been achieved on AUG at low collisionality with n = 2 RMP maintaining good confinement H-H(98,H-y2) approximate to 0.95. Advances have been made with respect to detachment onset and control. Studies in advanced divertor configurations (Snowflake, Super-X and X-point target divertor) shed new light on SOL physics. Cross field filamentary transport has been characterised in a wide parameter regime on AUG, MAST and TCV progressing the theoretical and experimental understanding crucial for predicting first wall loads in ITER and DEMO. Conditions in the SOL also play a crucial role for ELM stability and access to small ELM regimes.

Lipoproteins and metabolic control in hypertensive type II diabetics treated with clonidine
- 1988

Ingår i: Acta Medica Scandinavica. - 0001-6101. ; 224:2, s. 131-134

Tidskriftsartikel (refereegranskat)abstract
- Twenty patients with type II diabetes mellitus and hypertension (WHO stages I and II) participated in a 3-month double-blind cross-over study to evaluate the effects of clonidine (75-300 micrograms daily) on blood pressure, glycemic control and plasma lipoproteins. Already after 1 month's treatment with clonidine the systolic and diastolic blood pressures had decreased, from 168/103 to 161/98 mmHg (p less than 0.01). Fasting blood glucose and HbA1c concentrations were unaffected by 3 months' treatment. Similarly, plasma lipid and lipoprotein concentrations remained unchanged throughout the study (i.e. mean high and low density lipoprotein cholesterol concentrations were 0.89 and 3.87 mmol/l on placebo vs. 0.90 and 3.98 mmol/l on clonidine). Adverse effects were mild and tolerable, and consisted mainly of dryness of the mouth. We conclude that clonidine lowers the blood pressure in patients with type II diabetes without any adverse effects on glycemic control or plasma lipoproteins.

Early development evaluation of AZD8081: a substrate for the NK receptors
- 2011

Tidskriftsartikel (refereegranskat)abstract
- The purpose of the present study was to find out if AZD8081, a dual neurokinin (NK)1/2 receptor antagonist, was suitable for development of an oral, solid immediate release (IR) formulation and in a further perspective also as an oral extended release (ER) formulation. AZD8081 is a base with pK(a) values
