11. Ultrastructural and systematic studies of cecidomyiidae (Diptera)
Sammanfattning : Examination of the abdomen of the adult female and the head capsule of the mature larva indicates the grat utility of the Scanning Electron Microscope (SEM) in examining structures when searching for useful characters to deal with the taxonomy and phylogeny of gall midges (Diptera: Cecidomyiidae). Some of the structures found represent adaptations of limited value for phylogenetic considerations at higher levels. LÄS MER
12. Development and evaluation of an independent system for absorbed dose calculations in radiotherapy
Sammanfattning : The aim of this work was to develop, implement and evaluate an independent system with which to calculate the absorbed dose, delivered by high-energy X-ray beams, to the prescription point and the depth of dose maximum. The introduction of such a system in the clinical routine may help ensure high-quality treatment and avoidance of errors which may jeopardise the clinical outcome of the treatment (i. LÄS MER

15. Injuries among the elderly : study of fatal and non-fatal injury events
Sammanfattning : In view of the expected increase in the proportion of elderly in the population in most western countries, we studied injuries among the elderly (>60 years) by investigating hospital-treated injuries in inpatients and outpatients, and fatal injuries.One-year Hospital Injury Data - Even though the elderly made up only 15% of the injured in one year, they accounted for 42% of the total cost of trauma medical care, showing that injuries among the elderly place a disproportional burden on the health care system.
