Ineradicable Stain

Causes of Ineradicable Spurious Predictions in Qualitative Simulation

It was recently proved that a sound and complete qualitative simulator does not exist, that is, as long as the input-output vocabulary of the state-of-the-art QSIM algorithm is used, there will always be input models which cause any simulator with a coverage guarantee to make spurious predictions in its output. In this paper, we examine whether a meaningfully expressive restriction of this voca...

Silicone Softeners for Stain Repellent and Stain Release Fabric Finishing

During the last few years the use of fluorochemicals to provide stain repellency and/or stain release properties to apparel goods has rapidly grown. The use of fluorochemicals as well as durable press resins, however, has a detrimental effect on the fabric softness. Providing premium softness is key to satisfy the highly demanding aesthetic requirements of many of today’s apparel products. Alth...

Rapid trichrome stain.

A rapid trichrome stain procedure was evaluated. It saves considerable time, especially when only a few slides are stained, and allows for the accurate identification of amoebae and other fecal parasites.

Rapid flagella stain.

Leifson stain was modified to produce rapid staining of bacterial flagella on untreated microscope slides. The procedure was reliable when tested against a variety of motile and nonmotile bacteria.
