Novel non-ionic contrast media are efficiently prepared from generally available ionic contrast media or non-iodinated precursors. Particularly, polyhydroxyhalo-hydrocarbons are employed with a triiodo-substituted acylamido benzoic acids in aqueous weakly basic media to selectively substitute the amido nitrogen, followed by activation of the carboxyl group for amide formation.

An adhesive wafer (12), which is especially suitable for use as a faceplate for an ostomy appliance but may also be used as a wound dressing, has an adhesive layer (14) of hydrocolloid-containing skin barrier material and a flexible backing layer (15) extending over one surface of the adhesive layer. The opposite skin-contacting surface (14a) of the adhesive layer is embossed to provide a pattern ...

The invention relates to a method and a spectrometer for implementing the method of measuring a Raman spectrum, the method comprising generating at least two monochromatic optical excitation beams (330, 332) having known, different frequencies, generating a radiation target (382, 384) for each excitation beam (330, 332) in the object (380) to be measured, and measuring a Raman spectrum induced by ...

A papermaker's fabric is made by spirally winding a woven fabric strip. The fabric strip has first and second lateral edges, along which are a first and second lip, respectively. Each lip has at least one lengthwise yarn woven with crosswise yarns. Adjacent to and inward of the first and second lips on the fabric strip are a first and second gap, respectively, which lack lengthwise yarns but whose...

The present invention provides a superhard polycrystalline diamond or diamond-like element with improved wear resistance. Collectively called PCD elements for the purposes of this specification, these elements are formed with a binder-catalyzing material in a high-temperature, high-pressure (HTHP) process. The diamond material is formed and integrally bonded to a substrate containing the catalyzin...

A biaxially oriented monolayer or multi-layer polyester film which has semi-transmittability and reflectability, contains a pearlescent pigment having an average long diameter of 0.5 to 125 mu m and transmittance which satisfies the following expression (1): (parallel light transmittance/total light transmittance) x 100 >/= 3 This polyester film is used in the light sourc...

A method of penis lengthening including dividing the suspensory ligament down to the inferior public arch; dividing the fundiform ligaments; or dividing the first and second corpus cavernosum circumferentially. A method of widening a penis where a dermal fat graft is sutured to the exposed Bucks fascia. Post operative drug and exercise to maintain the outcome of penis lengthening or widening.

A method for retreading a solid tire comprises: wrapping uncured rubber around the periphery of said tire to form a green assembly; clamping said green assembly in a C mold, said C mold comprising spindles, said spindles having a gap there between; and curing said tire assembly.

A method for monitoring compliance with recommended hand-washing practices is disclosed. The method involves detecting the occurrence of an event that is specified in a hand-washing rule. The method also involves determining whether a person who is involved in the event complies with the hand-washing rule.
