Background: Exogenous ochronosis (EO) is a rare cutaneous disorder that disproportionately impacts skin of color and can be very challenging to treat. EO most commonly occurs secondary the continual chronic use hydroquinone resulting in an accumulation homogentisic acid polymerized ochre-colored pigment papillary dermis. There are few US cases date discussing clinicopathology color. From 1983 2...

a territorial isolation is a danger to the game population, causing deterioration called the inbreeding depression. the typical signs are anomalous body proportions, such as short lower jaw, shortened lifetime, weak physique and lower birth rate. this is caused by low number of game in the community. white colored deer is in the location of the czechrepublicbred in separation since 18th century...

We study the computational complexity of $c$-Colored $P_\ell$ Deletion and $C_\ell$ Deletion. In these problems, one is given a $c$-edge-colored graph wants to destroy all induced $c$-colored paths or cycles, respectively, on $\ell$ vertices by deleting at most $k$ edges. Herein, path cycle if it contains edges $c$ distinct colors. show that are NP-hard for each non-trivial combination $\ell$. ...

this paper investigated the effects of combining fibers with self-consolidating concrete (scc). 12 series of test specimens were prepared using three kinds of fibers including steel, polyphenylene sulfide (pps) and glass fibers with four different volumes fractions and one specimen without fibers as a reference sample. all plans were subjected to fresh concrete tests. for mechanical behavior of...

Abstract According to the demand of color prediction for colored yarn, two adjacent colors chosen from red (R), yellow (Y), green (G), cyan (C), blue (B) and magenta (M) fibers were combined with dark gray (O 1 ), medium 2 ) light 3 respectively, then ternary coupling‐superposition mixing was performed acquire a solid consisting three lightnesses, 18 units 18×(m+1)×n grid points. An integrated ...

Lightweight artificial muscle fibers that can match the large tensile stroke of natural muscles have been elusive. In particular, low stroke, limited cycle life, and inefficient energy conversion have combined with high cost and hysteretic performance to restrict practical use. In recent years, a new class of artificial muscles, based on highly twisted fibers, has emerged that can deliver more ...
