Background: Cervical cancer is a pervasive yet preventable killer. Although routine screening exams are available to aid in the early detection of cervical cancer, women often avoid getting their routine annual screening exams. One explanation of this could be due to the discomfort of speculum exams. One way to minimize the discomfort of the speculum exam is to use gel-lubricant. However, there...

OBJECTIVE Nonlubricated plastic specula can adhere to the vaginal introitus and cause discomfort with pelvic examination. We wanted to see if application of water-soluble gel lubricant to the plastic vaginal speculum would change the unsatisfactory cervical cytology diagnosis rate. METHODS Five public health family planning clinic sites were randomized to either water-soluble gel or water onl...

The implementation of nano-additives in machining fluid is significant for manufacturers to attain a sustainable manufacturing process. material removal rate (MRR) process transforming solid raw materials into specific shapes and sizes. This has many challenges due friction, vibration, chip discontinuity when aluminum alloy, which led poor accuracy affected the fatigue life developed material. ...

A thermodynamic model describing the phase transition of first order between structure states of lubricant material in the boundary friction regime is proposed. It is shown that lubricant melts with temperature increase or at shear of rubbing surfaces if the elastic strain (stress) exceeds the critical value. The phase diagram with domains of dry and sliding friction is constructed. The depende...

RATIONALE Chemical additives are incorporated into commercial lubricant oils to modify the physical and chemical properties of the lubricant. The quantitative analysis of additives in oil-based lubricants deposited on a surface without extraction of the sample from the surface presents a challenge. The potential of desorption electrospray ionization mass spectrometry (DESI-MS) for the quantitat...

Slippery liquid-infused porous surfaces (SLIPS) have emerged as a unique approach to creating that can resist fouling when placed in contact with aqueous media, organic fluids, or biological organisms. These are composed of essentially two components: liquid lubricant is locked within the protrusions textured solid due capillarity. Drops, immiscible lubricant, exhibit high mobility and very-low...

High specific strength and superior corrosion resistance are two key characteristics of the aerospace grade AA7075-T6 alloy. However, surface behavior is found to be deprived, because its being prone fretting fatigue adhesive wear under dry sliding conditions. Thus, improvement with retention microhardness alloy required for increasing wider application. For this, isomorphous precipitates soft ...
