We investigate homogeneity in the special Colombeau algebra on Rd as well as on the pierced space Rd \ {0}. It is shown that strongly scaling invariant functions on Rd are simply the constants. On the pierced space, strongly homogeneous functions of degree α admit tempered representatives, whereas on the whole space, such functions are polynomials with generalized coefficients. We also introduc...
Potential relationships between the development of nickel allergy and previous ear piercing or orthodontic treatment with nickel-containing appliances were studied in 294 patients. We found 77 (31.2%) of 247 patients with pierced ears were allergic to nickel compared to only three (6.4%) patients without pierced ears (p = 0.001), which confirms earlier suggestions that nickel allergy (as assess...
BACKGROUND Body art practices have emerged as common activities among youth, yet few studies have investigated awareness in different age groups of possible health complications associated with piercing and tattooing. METHODS We investigated perceptions of and knowledge about health risks. To highlight differences among age groups, we gathered data from students at high schools and universiti...
The tensile residual stress near pierced holes deteriorates the fatigue properties and hydrogen embrittlement resistance of automotive parts. Consequently, a simple shearing method that can reduce this type is highly desired in industry. In study, effect coining using scrap material on 10 mm diameter hole was investigated. fracture surfaces presented similar shapes because these parts were prod...
