Vol. 37 No. 5 • May 2012 • P&T® 261 mivacurium following a sales visit by a pharmaceutical representative. The carton of mivacurium was delivered to the pharmacy and was placed in stock next to metronidazole. Both products were packaged in foil overwraps. Before the error occurred, metronidazole had been the only foil-wrapped, premixed solution in the pharmacy; miva curium was not on the formul...

From last 50 years, electron beam therapy has an important radiation therapy modality. The electron beam from the LINAC is of size ∼ 2 mm, whereas the size required for actual treatment is usually larger than 2 × 2 cm up to 25 × 25 cm at the isocenter. In the present work, it is proposed to use dual scattering foil system for production of clinical electron beam. The foils for 6 to 20 MeV elect...

Air-lubricated foil bearings are used in a variety of applications such as turbomachinery, journal bearings, dentistry equipment, etc. [1–3]. One of the most intricate applications of air-lubricated foil bearings can be found in magnetic tape drives [4], where a magnetic tape moves over a read/write head and tape drive components such as guides (stationary) and rollers (rotating). Friction is a...

The reliability of wide-bandgap (WBG) semiconductors used as power electronics is closely related to the high thermal conductivity AlN-metalized substrates. Thus, bonding AlN ceramics with metals a key issue for production reliable This paper reports on new method producing AlN/Cu joints by employing novel film metallization process, which involves porous network Cu layer and Ag foil. microstru...

Metal–insulator–metal (MIM) nanogaps in the canonical nanoparticle-on-mirror geometry (NPoM) provide deep-subwavelength confinement of light with mode volumes smaller than V/Vλ < 10–6. However, access to these hotspots is limited by impendence mismatch between high in-plane k∥ trapped and free-space plane-waves, making in- out-coupling difficult. Here, constructing a nanoparticle-on-foil (NPoF)...

A new type of infrared imaging bolometer, known as the infrared imaging video bolometer ~IRVB! has been under development at the National Institute of Fusion Science ~NIFS! over the last year. A prototype of this diagnostic has been designed and constructed at NIFS and installed on the large helical device ~LHD! and successfully operated. This diagnostic utilizes a 6639030.001 mm gold foil moun...

Compliant foil gas lubricated bearings are used for the support of light loads in the order of few kilograms at high speeds, in the order of 50,000 RPM. The stiffness of the foil bearings depends both on the stiffness of the compliant foil and on the lubricating gas film. The stiffness of the bearings plays a crucial role in the stable operation of the supported rotor over a range of speeds. Th...

High aspect ratio of WO3-loaded TiO2 nanotube arrays have been successfully synthesized using the electrochemical anodization method in an ethylene glycol electrolyte containing 0.5 wt% ammonium fluoride in a range of applied voltage of 10–40 V for 30 min. The novelty of this research works in the one-step formation of WO3-loaded TiO2 nanotube arrays composite film by using tungsten as the cath...

Definition. Let Kn denote the complete graph of n vertices. The complete multigraph λKn is the complete graph Kn in which every edge is taken λ times. The t-foil (or the t-windmill) is a graph of t edge-disjoint K3’s with a common vertex and the common vertex is called the center of the t-foil. In particular, the 2-foil, the 3-foil, and the 4-foil are called the bowtie, the trefoil, and the qua...
