The goal of the current study was to construct a reference database against which misarticulations of /s/ can be compared. Acoustic data for 26 typically speaking 9- to 15-year-olds were examined to resolve measurement issues in acoustic analyses, including alternative sampling points within the /s/ frication; the informativeness of linear versus Bark(More)
We have studied the nocturnal flight behaviour of the common swift (Apus apus L.), by the use of a tracking radar. Birds were tracked from Lund University in southern Sweden during spring migration, summer roosting flights and autumn migration. Flight speeds were compared with predictions from flight mechanical and optimal migration theories. During spring,(More)
To determine the reliability and validity of a previously identified "suicide cluster" in the Percept-genetic Object-Relation Test (PORT), which test documents subliminal perception of object-relation pictures, 20 suicide attempters and 70 controls were investigated. The correspondence between scores assigned by two judges was 95%-100%. The suicide-cluster(More)
i " Only a life lived for others is a life worthwhile "-Albert Einstein ii iii Abstract Background: Non-communicable diseases (NCDs) are the leading causes of morbidity and mortality among adults in Vietnam. Little is known about the magnitude of socioeconomic inequalities in NCDs and other NCD-related factors in urban areas, in particular among the poor(More)
Trophic use by Atlantic cod Gadus morhua juveniles was examined early and late in the shift from pelagic to benthic habitats. Changes in the proportion of pelagic copepods, estimates of benthic prey indicated by isotope mixing models and stable-isotope values between sample periods suggested a gradual shift towards a benthic niche. Values of the trophic(More)
Size distribution measurements performed at five different stations have been investigated during a one-year period between 01 June 2000 and 31 May 2001 with focus on diurnal, seasonal and geographical differences of size distribution properties. The stations involved cover a large geographical area ranging from the Finnish Lapland (67 • N) 5 down to(More)
During transportation of patients under skull traction, swinging of the weights produces acceleration forces that not only can cause pain and discomfort for the patient, but also can cause worsening of the cervical fracture or dislocation. Skull traction systems also involve friction forces. In a system with one pulley, the friction forces were 10 to 21.5%(More)
