A compact and low-weight sputtering unit for in situ investigations of thin film growth at synchrotron radiation beamlines.

In this work, we report on a highly variable, compact, and light high-vacuum sputter deposition unit designed for in situ experiments using synchrotron radiation facilities. The chamber can be mounted at various synchrotron beamlines for scattering experiments in grazing incidence geometry. The sample position and the large exit window allow to perform x-ray experiments up to large q values. The sputtering unit is easy to mount on existing experimental setups and can be remote-controlled. In this paper, we describe in detail the design and the performance of the new sputtering chamber and present the installation of the apparatus at different 3rd generation light sources. Furthermore, we describe the different measurement options and present some selected results. The unit has been successfully commissioned and is now available for users at PETRA III at DESY.

[Treatment of hyperlipoproteinemia in patients with diabetes mellitus]. / Therapie von Hyperlipoproteinämien bei Patienten mit Diabetes mellitus.

In a large percentage of cases, diabetes mellitus leads to hyperlipidemia. In addition to the diabetes-related secondary hyperlipidemias, all types of primary disturbances of lipid metabolism can also be observed in diabetics. Depending upon the degree of severity and type of metabolic disorder presenting, not only suitable dietetic treatment, but also the various lipid-lowering drugs, fibrates, nicotinic acid, probucol, cholestyramine and the HMG-CoA reductase inhibitors should be introduced into therapy. As in all groups with an elevated coronary risk, strict management of the lipid levels is mandatory in diabetics, too.

[Stages of grief in coping with diabetes?]. / Trauerphasen in der Diabetesbewältigung?

Forms of coping with diabetes were determined on the basis of self-ratings of emotions (depressive, sad, angry, anxious) and responses on a 30-item "stages of grief" questionnaire by 52 inpatients aged between 25 and 50 (diabetes duration 1 to 35 years) at the beginning of a 12 day diabetes education program. Psychometric qualities of the instruments were evaluated. To test empirically the notion of grief stages in coping with diabetes, the frequency of emphasis on one or more emotional areas or stages of grief was determined and tested to ascertain whether various conditions occurred more frequently than was expected by chance. Results indicated that shortly after diabetes manifestation scores on protest and depression with respect to diabetes were elevated. The majority of cases could not be assigned to a single emotion or stage of grief but displayed negative emotional reactions in different content areas simultaneously. Consequently the concept of grief stages for coping with diabetes as well as recommendations based on this concept are questioned.
