Abstract The enduring contributions of low temperature plasmas to both technology and science are largely a result the atomic, molecular, electromagnetic (EM) products they generate efficiently such as electrons, ions, excited species, photons. Among these, production light has arguably had greatest commercial impact for more than century, plasma sources emitting photons over portion EM spectru...

A cheap method by which hospital blankets may be effectively disinfected (approximately 3d. per blanket) is described. A recommendation is made that blankets from the patients' beds be divided into: ;socially dirty' blankets to be laundered, possibly at infrequent intervals; and ;socially clean' blankets to be disinfected frequently. The wide range of a synthetic phenolic compound is described....

Aspergillus fumigatus spores in food may represent an infectious risk for neutropenic patients. We examined the efficiency of disinfection procedures applicable to foods for eradication of A fumigatus. Boiling and microwave treatment fully decontaminated an experimental spore suspension and naturally contaminated liquid foods (reconstituted dried food, herbal tea). Full decontamination of exper...

Ten brands of hydrogel contact lenses were selected from five of the six British Approved Name lens classification groups to test in vitro the effects of repeated heat disinfection by means of microwave irradiation. Each lens type was tested over a number of cycles corresponding to its scheduled number of wearing days. The total diameter and back vertex power of all 80 test and 12 control lense...

BACKGROUND: The current standards for chlorine and monochloramine disinfection of drinking water were established using information obtained from bench-scale disinfection experiments of monodispersed hepatitis A virus. It is not clear whether these standards are sufficient for the four virus types listed on the CCL2. Several disinfection studies have been conducted on representative coxsackievi...

Ultraviolet light (UV) is a recognized disinfection alternative to chlorine and ozone in many applications from drinking water to wastewater treatment. UV provides effective disinfection without production of problematic disinfection byproducts. Information on the mechanism and application of UV for drinking water disinfection is presented. Advantages and disadvantages of the technique are disc...

Every year, the human impact on world’s water sources becomes more pronounced. One of triggers to this increase is use ineffective wastewater and sludge treatment systems. Recently, number studies microwave processing in handling liquid municipal industrial waste has increased. This paper discusses heat treatment, change properties, decomposition substances, removal metals, demulsification, pyr...

BACKGROUND Stethoscopes are contaminated with bacteria, but predictors of stethoscope disinfection frequency are unknown. We sought to describe health care provider stethoscope disinfection attitudes and practices and determine predictors of frequent disinfection. METHODS We used an anonymous online survey of nurses, nurse practitioners, and physicians at a pediatric hospital. We assessed fre...
