This is a report of a novel tactile musical instrument. This instrument is called "Multi Rubbing Tactile Instrument (MRTI2015)", using ten pieces of "PAW sensor produced by the RT corporation". Previous research was focused on "untouchable" instruments, but this approach is fully tactile "rub" and "touch". The ten PAW sensors are assigned on the surface of the egg-like plastic case to fit the t...

In their natural environment, capuchins select certain plants, containing secondary compounds with bactericide, insecticide or fungicide properties, to rub their pelage energetically (i.e. fur rubbing). Fur rubbing can be performed in solitary, or collectively in subgroups of variable size and composition, and most of the time fur rubbing happens in synchrony with other group members. The aim o...

The electrostatic charge on nylon, polypropylene (PP), and polytetrafluoroethylene (PTFE) after rubbing against stainless steel and against each other was examined using a newly developed rubbing device with automated features. It is observed that the charge generated on PTFE and PP increases as the contact force increases, while the charge generated on nylon is not affected by the contact forc...

The three-component mixture showing the V-shaped switching in a rubbing cell is investigated using a temperature gradient cell (TGC) where the epitaxial method of alignment, but without an alignment layer, is used. The molecular alignment and the switching characteristics in a TGC are compared with the rubbing sandwich and the open cells. The uniform or the twisted state is observed in the TGC,...

This paper describes the design and preliminary evaluation of a glove with individual sensors covering the tips of the thumb, third, and fourth fingers, plus grids of smaller sensors lining the palmar sides of the first and second fingers. The glove senses two types of gestures: rubbing the thumb against the first two fingers, and tapping the thumb on the tip of any of the four fingers, alone o...

Random lasers from dye-doped nematic liquid crystal (DDNLC) cells with different rubbing methods were observed due to different random ring cavities that were formed. Through constructing cells with different rubbing methods on the forward and backward surfaces of light-emitting sides, we can get two random laser beams with different polarization directions from one DDNLC cell at the same time,...

Functional additives, particularly extreme pressure and antiwear additives, in formulated oil will compete to adsorb and function in tribological contacts. A low-polarity commercial base oil, poly-α-olefin (PAO), blended with zinc dialkyl dithiophosphates (ZDDP) has been studied. The tribological performance was evaluated using a ball-on-disk test rig under mixed rolling-sliding conditions in t...

Health risks posed by dermal contact with PCB-contaminated porous surfaces have not been directly demonstrated and are difficult to estimate indirectly. Surface contamination by organic compounds is commonly assessed by collecting wipe samples with hexane as the solvent. However, for porous surfaces, hexane wipe characterization is of limited direct use when estimating potential human exposure....

PURPOSE To report a young child with bilateral keratoconus in the context of vernal keratoconjunctivitis (VKC) who developed bilateral corneal hydrops associated with eye rubbing, and to discuss the pathogenesis and review the pertinent literature. CASE REPORT A seven-year-old girl with VKC and asymmetric keratoconus developed corneal hydrops due to habitual eye rubbing. Corneal edema subside...
