We consider a mesoscopic ring connected to external reservoirs by tunnel junctions. The ring is capacitively coupled to an external gate electrode and may be pierced by a magnetic eld. Due to strong electron–electron interactions within the ring the conductance shows Coulomb blockade oscillations as a function of the gate voltage, while Aharonov–Bohm interference e ects lead to a dependence on ...

Stinging mechanisms generally deliver venomous compounds to external targets. However, nematocysts, the microscopic stinging organelles that are common to all members of the phylum Cnidaria, occur and act in both external and internal tissue structures. This is the first report of such an internal piercing mechanism. This mechanism identifies prey items within the body cavity of the sea anemone...

becoming more and more common. In one study of college students seen at the Mayo Clinic, 10 of 218 males (4%) and 37 of 228 females (16%) had tongue piercings.1 About half of these students had allowed their tongue piercings to close over time. The study also found that 17% of all body piercings were associated with complications ranging from insignificant to life­threatening. Another study of ...

The aim of this study is to investigate the utilization of silkworm cocoon waste, such as pierced or stained cocoons, as a sorbent material for the removal of motor and vegetable oils from water. The oil-sorption capacity, rate and reusability of the material were evaluated. The results show the high sorption capacity of the silkworm cocoon waste sorbent (42-52 g(oil)/g(sorbent) for motor oil a...

In this work three capsule-based dry powder inhalers, available for generics product development, were compared. Two technologically different dry powder formulations were used in order to relate the capsule piercing position and motion in the device to their aerodynamic performance. A "pierce and inhale" design, in which the capsules pierced with RS01, HandiHaler or Turbospin devices were aero...

Although body piercing procurement continues to increase, 13% to 18% of them are removed. Reasons for piercing removal in college students were examined with three groups: (a) those who kept all their piercings, (b) those who removed some, or (c) those who removed all of their body piercings. Of the sample, 41% were still pierced; 50% in their lifetime. Their major purpose for the body piercing...

Sphenoidal sinus foreign bodies are very rare entities that are often associated with a cranial and/or orbital trauma. In this paper, a case of a metallic foreign body that pierced the sphenoid sinus and penetrated into the intracranial space due to a work accident is presented. A 29-year-old male was referred to our clinic due to a right orbital penetrating trauma. Skull X-ray and computed tom...

The ultrastructure of the 'cuticle' of Dipylidium caninum is described. The presence of mitochondria within the 'cuticle' and the connexion between it and subcuticular cells indicates that the outer covering of this cestode is of living cells forming an epidermis. On its external surface the epidermis is folded into finger-like microthriches and its thickness is pierced in places by pore-canals...

The purpose of this article is to highlight the importance of including cosmetic body-piercing and tattooing in HIV prevention and education. Little information about risks associated with tattoos or having one's body pierced is evident in the health promotion and disease prevention literature, particularly among adolescents, ethnic groups, and incarcerated populations. It is incumbent that pre...

Recently an increasing number of patients with complications related to pierced body jewellery have been seen. Often removal of the jewellery is indicated. Removal of these items may also be required for radiological purposes. If the doctor is familiar with the opening mechanism of the item, removal is not usually difficult. Uninformed attempts at removal may cause unnecessary trauma and distre...
