A (homogeneous) d-interval is a union of d closed intervals in the line. Using topological methods, Tardos and Kaiser proved that for any finite collection of d-intervals that contains no k + 1 pairwise disjoint members, there is a set of O(dk) points that intersects each member of the collection. Here we give a short, elementary proof of this result. A (homogeneous) d-interval is a union of d ...

This paper presents the motion characteristics for high-speed catamarans travelling in waves. Two mathematical models, threedimensional translating-pulsating source distribution technique and three-dimensional pulsating source distribution technique, are used for predicting the motions of the wave-piercing catamaran in oblique waves. The comparison between numerical predictions and experimental...

Insufficient knowledge of medical chemicals and their improper use have destructive effects. Accidental exposure to chemicals on facial tissue may result in large facial defect. For ages the tradition of piercing nose is common but improper use of unknown chemical for piercing has deleterious effect. Mostly rhinectomy defects are acquired caused by trauma or malignant diseases. Prosthetic rehab...

Body piercing and tattooing flourish on American campuses. The theoretical framework of symbolic interaction and subculture identity were used to examine two similar studies (methods, sample, and tools) for building a composite of influences associated with body art and further understand the psychosocial dimensions. In data from Armstrong, Owen, Roberts, and Koch (2002a, 2002b), and the descri...

This study aimed to analyze the knowledge of nursing auxiliaries and technicians in handling and disposing of piercing-cutting material and describe their performance. This qualitative-descriptive research was carried out with three nursing auxiliaries and 12 technicians at a medium-size hospital, totaling 15 participants interviewed through a semi-structured script. Discourse was analyzed thro...

CONTEXT Myiasis is caused by larval infestation that usually occurs in exposed wounds. Dermatobia hominis is the most common fly species responsible for this parasitic infection. Genital piercing is an ornamental practice used in certain social circles. At placement, it transverses the skin surface and, as such, may be related to complications. CASE REPORT We report a case of a 31-year-old ma...

BACKGROUND Breast abscesses are typically seen in the setting of complicated mastitis in lactating women. Abscesses resulting from foreign bodies are not commonly seen in the breast. Over the past few decades, body piercing has become increasingly common, yet the infectious morbidity resulting from it is not well recognized. A breast abscess associated with nipple piercing is described in this ...

Children imitating adults often appear to indulge in harmless fun, however at times these activities have more serious implications. The recent fashion of body piercing among adults has encouraged children to have similar procedures or imitate them by applying small magnets to sustain the jewellery used in piercing in position. This paper describes a series of 24 cases presented to the Sheffiel...

Countries are increasingly using tax policy as an instrument to navigate through the recent global financial difficulties, and China is no exception. In an effort to avoid the loss of tax revenue resulting from the utilization of foreign holding companies, the Chinese tax authority issued Circular 698 granting itself the authority to tax transactions between foreign entities taking place outsid...
