We prove the nonexistence of two-dimensional solitary gravity water waves with subcritical wave speeds and an arbitrary distribution of vorticity. This is a longstanding open problem, and even in the irrotational case there are only partial results relying on sign conditions or smallness assumptions. As a corollary, we obtain a relatively complete classification of solitary waves: they must be sup
This paper examines how organizations for Boy Scouts and Girl Scouts in Sweden dealt with domestic and parental issues, from the movement’s inception in 1910 to 1960. The perspective is twofold.

BACKGROUND: To investigate the correlation between various orthopedic conditions and overweight/obesity at the Department of Orthopedics, Malmö University Hospital Sweden. Obesity is associated with numerous major medical conditions. Although the relationship between gonarthrosis and osteoarthritis and body mass index (BMI) is well recognized, other orthopedic conditions have been less well studie
Anaesthesia with closed anaesthetic systems demands knowledge of the physiology of the patients and of how the various anaesthetic gases behave in the organism as only the gases which the patients produces and absorbs are eliminated and replaced. The system is educational as it provides knowledge of the genuine absorption of oxygen and anaesthetic gases. The method is favourable to the environment
