Sound working of transmitting power is very essential. For immaculate working of the machines, bearings play an important and critical role. Standard monitoring methods of performance evaluation of rolling element bearings with high degree of reliability are yet to be explored. Authors have proposed rolling element bearing test rig for the same [3]. The formulation requires essentially the elec...
In many cases, polyol ester (POE) and polyalkylene glycol (PAG) lubricants used with HFC refrigerants, may cause long-term reliability and stability problems. Mineral oil lubricants are much more stable in the long run and do not suffer from stability problems nearly as much as POE and PAG lubricants. HFC based refrigerants and blends are, in general, nonmiscible in mineral oils, and will not r...
Infertility affects approximately 15% of couples, and in about one-third the primary cause is a male factor. Patients undergoing infertility investigations frequently experience sexual dysfunction, which often is due to inadequate vaginal lubrication. This can lead to increased use of coital lubricants. The effects of such lubricants on sperm motility have not been widely studied, although sper...
OBJECTIVE To evaluate the effect of vaginal lubricants Pre-Seed, FemGlide, Astroglide, and Replens on human sperm motility and chromatin integrity. DESIGN Prospective, comparative, in vitro study. SETTING Andrology laboratory at tertiary care hospital. PATIENT(S) Thirteen normozoospermic donors. INTERVENTION(S) Semen samples from 13 subjects were incubated in human tubal fluid media (HT...
A number of environmentally adapted lubricants have been proposed in response to the environmental and health impacts of metalworking fluids (MWFs). The alternatives typically substitute petroleum with vegetable-based components and/or deliver minimum quantities of lubricant in gas rather than water, with the former strategy being more prevalent than the latter. A comparative life cycle assessm...
Boat lubricants are continuously released into the marine environment and thereby cause chronic oil pollution. This study aims to isolate lubricant-degrading microorganisms from Thai coastal areas as well as to apply a selected strain for removal of boat lubricants. Ten microorganisms in the genera of Gordonia, Microbacterium, Acinetobacter, Pseudomonas, Brucella, Enterococcus and Candida were ...
Until now, we’ve only evaluated gel’s impact on test results Studies comparing lubricating gel and water have conclusively shown that a small amount of gel, used on the outside of the speculum blades, does not interfere with either Pap testing or detection of Chlamydia trachomatis. One liquid-based cytology manufacturer, however, discourages the use of lubricants with “carbomers” or “carbopol p...
The primary objective of this study was to compare the lubrication properties of micronized poloxamer 188 (Lmicrotrol micro 68) and micronized poloxamer 407 (Lmicrotrol micro 127) with certain conventional lubricants such as magnesium stearate and stearic acid. The secondary objective was to use these micronized poloxamers as water-soluble tablet lubricants in preparation of effervecsent tablet...
Electrical impedance of the cochlear implant lubricants hyaluronic acid, oxycellulose, and glycerin.
Hyaluronic acid (Healon), oxycellulose (hydroxypropyl methylcellulose), and glycerin are lubricants used in cochlear implant surgery for atraumatic deep insertion of the electrode array into the scala tympani. The electrical impedances of these three lubricants were measured to assess possible effects on intraoperative evoked response measurements, such as the electrically evoked stapedius refl...
