Rats, mice and gerbils were continuously exposed to 150 ppm trichloroethylene (TCE) for 30 days. In all three species, there was a marked increase in liver weight. In mice the weight increased more (86%) than in rats and gerbils (20%). After exposure the activity of acid phosphatase, a lysosomal marker enzyme, was tested in different brain areas, using a system which had a limit of detection of ±
Objective: The aim of the present study was to map out what kind of psychotropic drugs are prescribed for elderly residents in assisted-living homes and how they relate to age, sex, form of living, psychiatric diagnosis, care needs and mental health status, and to identify factors of importance for their use; and to study the indication for treatment and the evaluation of the effects of treatment.
During the past century, Lake Takern and Lake Krankesjon, southern Sweden, have shifted repeatedly between a state of clear water and abundant submerged vegetation, and a state of turbid water and sparse vegetation. Long-term empirical data on such apparently alternative stable state dynamics are valuable as complements to modeling and experiments, although the causal mechanisms behind shifts are
We are investigating means of handling microparticles in microfluidic systems, in particular localized acoustic trapping of microparticles in a flow-through device. Standing ultrasonic waves were generated across a microfluidic channel by ultrasonic microtransducers integrated in one of the channel walls. Particles in a fluid passing a transducer were drawn to pressure minima in the acoustic field

Measurements of the Xi(-) and (Xi) over bar (+) masses, mass differences, lifetimes and lifetime differences are presented. The (Xi) over bar (+) sample used is much larger than those used previously for such measurements. In addition, the S production rates in Z -> b (b) over bar and Z -> q (q) over bar events are compared and the position xi* of the maximum of the distribution in Z -> q (q) over
Popular Abstract in Swedish Införandet av 1993 års skogspolitiska beslut med ett jämställt miljö- och produktionsmål, belyser den historiskt befästa konflikten mellan allmänintresse och egenintresse: statens vilja och behov att styra produktion och avkastning kontra den enskilde skogsägarens rätt att själv bestämma över sin skog. Idag har denna konflikt styrt över mot en statligt uttalad målsättniThis dissertation analyzes the changes in the way Swedish forest policy has been developed and implemented in the past few decades. Its primary focus is on the period from the adoption of new legislation governing forestry in 1993 to date, though the historical antecedents of the more recent developments are also discussed. The dissertation focuses primarily on the interplay between changes in the
Dilute solutions of catanionic vesicles formed by the mixed single-chained (sodium dodecylsulphate, SDS) and double-chained (didodecyldimethylammonium bromide, DDAB) surfactants have been investigated by differential scanning calorimetry. It is for the first time reported a gel-to-liquid crystal phase transition temperature, T-m, in this type of mixed vesicles. The SDS-rich vesicles (at X-SDS = 0.
I examined production of, and emergence from, diapausing eggs, together with planktonic dynamics of three cladoceran genera (Bosmina, Ceriodaphnia, and Daphnia) for 16 months in a shallow lake. In a complementary field experiment I manipulated environmental variables potentially important as cues for induction and termination of diapause. Ceriodaphnia and Daphnia, but not Bosmina, were dependent o
In this paper we address the test scheduling problem for system-on-chip designs. Different from previous approaches where it is assumed that all tests will be performed until completion, we consider the cases where the test process will be terminated as soon as a defect is detected. This is common practice in production test of chips. The proposed technique takes into account the probability of de

Vitamin D (vit D) deficiency is common in the elderly, and the aim of this study was to investigate whether vit D deprivation in ovariectomized (ovx) and normal rats would reduce fracture strength. Forty mature female Wistar rats were randomized into four groups: two were ovariectomized (ovx) and two were sham-operated (sham). One ovx and one sham group were fed a vit D-deficient diet (Ovx-D and S
Objectives To elucidate risk factors for high state anxiety in women referred for colposcopy. Design Prospective cohort study. Setting Department of Gynaecology, Malmo University Hospital, Sweden. Population A total of 100 consecutive women referred for colposcopy for the first time after an abnormal cervical smear. Methods Women in the study group completed prior to colposcopy the State-Trait Anx
Vertebral fractures are associated with back pain and disability. There are, however, few prospective data looking at back pain and disability following identification of radiographic vertebral fracture. The aim of this analysis was to determine the impact of radiographically identified vertebral fracture on the subsequent occurrence of back pain and disability. Women aged 50 years and over were r
