OBJECTIVE To detect an outbreak-related source of Legionella, control the outbreak, and prevent additional Legionella infections from occurring. DESIGN AND SETTING Epidemiologic investigation of an acute outbreak of hospital-associated Legionnaires disease among outpatients and visitors to a Wisconsin hospital. PATIENTS Patients with laboratory-confirmed Legionnaires disease who resided in ...

The off-the-shelf Optical Character Recognition (OCR) engines return mediocre performance on the decorative characters which usually appear in natural scenes such as signboards. A reasonable way towards the so-called camera-based OCR is to collect a large-scale font set and analyze the distribution of font samples for realizing some character recognition engine which is tolerant to font shape v...

ni-w coatings, compared to pure nanocrystalline ni, exhibit higher hardness and wear resistance. in some cases, these coatings are considered as environmental friendly alternatives for hard chromium coating. till now, most of ni-w coatings have been produced by direct current electrodeposition from alkaline baths. in this study square pulse current was used for deposition of ni-w precipitates f...

in this study, physical vapor deposition (pvd) ti-cr-n coatings were deposited at two different temperatures100 and 400ºc on hardened and tempered tool steel substrates. the influence of the applied deposition temperature on the physical and mechanical properties of coatings such as roughness, thickness, phase composition, hardness and young’s modulus were evaluated. phase compositions were stu...

BACKGROUND AND OBJECTIVES Although nanosecond-domain lasers have been the mainstay of laser tattoo removal for decades, recent disruptive innovations in laser design have introduced a new class of commercial Q-switched lasers that generate picosecond-domain pulses. STUDY A picosecond-domain, Nd:YAG laser with a KTP frequency-doubling crystal was used to treat 31 decorative tattoos in 21 subje...

arquetry, also known as moaragh, derived from intarsia or inlay, is the ar t and craft of producing pictures and decorative designs by the skillful use of the grain, figure, and color of thin veneers of wood and other materials. In marquetry, the design is applied to a prepared base material, unlike the related craft of inlay where decorative bandings or designs are let into a solid item for em...

Abstract: Decorative henna skin painting can provoke severe reactions in the skin. We report 3 cases of unusual and persistent hyperpigmentation following nonpermanent henna tattoo, which alerted us to identify an additional side effect.

in the present study, ni-p-cnt composite coating was successfully fabricated via electroless plating. scanning electron microscopy (sem) was used to characterize the coatings. the effect of cnts concentration in the bath on its content in the composite coatings was studied. furthermore, the corrosion behaviour of the coatings with different contents of cnts was evaluated using tafel polarizatio...

in this study, the potential use of nano-coatings for food packaging industry has been investigated. therefore, this study has been presented in three sections: the application of nanocoatings in the food industry, natural, edible and biodegradable nano coatings. the use of nanoscale or multiatomic coatings have presented specific features in the packing industry. coatings which have shown thei...
