Each chromatophore is surrounded by muscles that change how the pigment is displayed by relaxing or contracting. A publication from the Smithsonian Institution likens the phenomenon to a drop of ink on a rubber band: when the band is loose, the color is concentrated in one spot and not readily...
Good sunglasses are extremely effective "light conditioners." They modify incoming light to match it to your eyes. In the next section we will discuss all of the different technologies used by sunglass manufacturers to modify light. In order to understand those technologies it is important to unde...

Asiatic acid (Figure 6)is another natural derivative of oleanolic acid. This compound is known to be clinically effective on systemic scleroderma, abnormal scar formation and keloids [24]. Again, the poor solubility of this compound in water limits its bioavailability and hence hinders its usage ...
Suppose they each have the same income of $100,000, and the same effective tax rate (after consulting the marginal tax rate tables) of 17%. Brenda took the standard deduction of $14,600, but she’s owed $4,000 in tax credits. Andrew, meanwhile, had $4,000 in itemized deductions ...
In calculating a simple average, orarithmetic mean, all numbers are treated equally and assigned equal weight. But a weighted average assigns weights that determine in advance the relative importance of each data point. In calculating a weighted average, each number in the data set is multiplied ...
a database query is a request for data from a database management system (dbms). it allows you to retrieve, manipulate, and analyze data stored in the database by using structured query language (sql) statements. how can i write an effective database query? to write an effective database...
Effective project management is the key to completing any project on time and within budget. Within every project there are always multiple issues that need to be tracked, prioritized, and managed. In this business scenario, MRVL Company has several projects that must be completed on time for th...
This structure makes cuticle extremely strong, as well as highly effective at keeping the spider from drying out, but the material does have one serious drawback. While it's flexible enough for movement, it can't expand like human bones and tissue -- in other words, it can't grow. In ...
This is consistent with the aromatic residues remaining stickers. These data support our prediction that Lys and Asp residues do not act as stickers. Instead, they modulate the driving forces for phase separation through a combination of increased effective solvation volume, electrostatic repulsions, ...
