Metallic piercing which have lack of resistance to sweat corrosion might be able to release metallic ions in the local tissue producing adverse effects in the human body, including allergic contact dermatitis (ACD). The aim of this study was double: 1) the metallic characterization of piercings and 2) the release of metals (Al, Co, Cr, Cu, Fe, Ir, Mn, Ni, Pd, Pt, Rh, Ti, V and Zn) in artificial...

Successful application of many implantable medical devices often depends on the technique used for attaching the devices to living tissue. Although mechanical attachment techniques that use micro-scale piercing elements are very promising, the fabrication of the micro-scale piercing elements poses considerable challenges. In this paper, the use of the mechanical micromilling process for fabrica...

INTRODUCTION Heart injuries can be classified as penetrating and non-penetrating (blunt). Penetrating wounds are usually caused by stabbing with a piercing object, weapon or projectiles--missiles. The right atrium is damaged in most cases, because of its anatomical position--making the most of the anterior side of the heart. Morbidity caused by stabbing injuries to the heart is 20%-30%, while p...

Piercings and tattoos have become very popular in western society in recent decades, particularly among younger generations. Reports of medical complications associated with these decorative techniques have increased in parallel with the rise in their popularity. Due to their high frequency, adverse cutaneous reactions are particularly important among these potential complications. Tattoo-relat...

The normal offset decomposition is a recent method to approximate images consisting of smoothly colored areas separated by smooth contours. In contrast to wavelet approximation methods, that perform suboptimally in this setting, this method is non-linear; the decomposition depends on the actual data. In every iteration new points are added by searching from the midpoint of the edges of the prev...

Background. Dermal piercings have recently become a fashion symbol. Common complications include hypertrophic scarring, rejection, local infection, contact allergy, and traumatic tearing. We report a rare case of Mycobacterium fortuitum following a dermal piercing and discuss its medical implications and treatments. Case. A previously healthy 19-year-old woman presented complaining of erythema ...

The uniqueness theorem is proved for the linearized problem describing radiation and scattering of time-harmonic water waves by a vertical shell having an arbitrary horizontal cross-section. The uniqueness holds for all frequencies, and various locations of the shell are possible: surface-piercing, totally immersed and bottom-standing. A version of integral equation technique is outlined for fi...

surface-piercing propellers (spps) have been widely used in high speed craft due to some desirable features such as high efficiency, omission of resistance of equipment attached to the propeller and proper functioning of cavitation. unlike the submerged propellers, theoretical methods have no significant application on simulation of sppsbecause of problems related to modeling of these propeller...
