A differential diagnosis must be made between transient yellow discoloration of the nails and yellow nail syndrome. We highlight some practical aspects of yellow nail discoloration.

Background The aim of this study was to evaluate the discoloration induced by CEM cement, Portland cement (PC) and MTA mixed with propylene glycol (MTA-PG) in comparison to White MTA. Material and Methods Ninety extracted premolar and canine teeth were resected 2 mm below the CEJ. The coronal part of crown was prepared with peeso reamer and Gates-Glidden drills, and the specimens were randoml...

A non-empty set X of a carrier A of an algebra A is called Q-independent if the equality of two term functions f and g of the algebra A on any finite system of elements a1, a2, . . . , an of X implies f(p(a1), p(a2), . . . , p(an)) = g(p(a1), p(a2), . . . , p(an)) for any mapping p ∈ Q. An algebra B is a retract of A if B is the image of a retraction (i.e. of an idempotent endomorphism of B). W...

This study examined the effect coextruding a clear HDPE cap layer onto HDPE/wood-flour composites has on the discoloration of coextruded composites exposed to accelerated UV tests. Chroma meter, XPS, SEM, and UV vis measurements accounted for the analysis of discoloration and degree of oxidation of both uncapped (control) and coextruded composites before and after UV exposures. Two separate dis...

We have designed a novel interface for interactive storytelling, where users manipulate physical objects to access various portions of a narrative. The story is designed so that the physical artefacts play meaningful parts in the narrative, thus blurring the line between story and interface. In informal tests and demonstrations users found the interaction easy to understand, thus indicating thi...

The purpose of this article is to present a contemporary picture of the Halliwick Concept– from Water Specific Therapy (WST) to the Ten-Point-Program (TPP) and to identify potential areas of further development by proposing a collaborative approach using the Halliwick Concept. The authors acknowledge differences in philosophies of both WST and TPP, and propose that the Halliwick Concept can ser...

In this paper we discuss the problem of collaborative monitoring of unauthorized persons, trying to deceive a face recognition based admission control system. We propose an efficient collaborative scheme, based on the TPP algorithm proposed in [2], that relies on probabilistic local information flooding. Combining their collective knowledge, the various units of the system can identify maliciou...
