According to the Food and Drug Administration, the use of artificial tanning devices is not recommended for anyone.

A final example of a mass-sensitive MIP device is a B AW sensor for determination of phenacetin in human serum and urine (Tan, Peng, et al. 2001). A phenacetin imprinted polymer was synthesized and used as the artificial recognition element on a piezoelectric element. 

Functional oxide materials play an important role for applications in microwave communication and sensor systems. Whereas silicon and GaAs represent the basic materials for the digital part of communication and sensor systems, the analogue parts require high quality factors and low losses, which cannot be fulfilled by semiconductors. Oxide insulators provide extremely low microwave losses expressed by the value of its loss tangent tan 5 = Im(er)/Re(er). The functionality of oxides in microwave devices or circuits can be classified as follows ... 

Dielectric loss will also degrade device performance and affect the switching power through its dissipative effects. As can be seen in Table 4, the dielectric losses are also low and nondispersive. The decrease in tanS in PMMA with frequency indicates that the losses are conductive, and probably due to impurity ions.

Now, the Froude number is equal to VjJ. For the triangular weir to be a measuring device, the flow must be critical near the weir. Thus, near the weir, the Froude number must be equal to 1. D, in turn, is AIT, where T= 2y tan. Along with the expression for A in Equation (3.11), this will produce D = yJ2 and, consequently, = Jgyc/2 for the Froude number of 1. With Equation (3.2), this expression for yields y = (4I5)H and, thus, = j2gHI5. (4/5)H may be... 

When a dielectric resonator is coupled with microwave circuits, the dielectric material responds to the frequency. The frequency selectivity of the microwave device depends on the loss quality of the materials. The selectivity Q ) of the dielectric materials is defined as the ratio of/ to A/, and the Q approximates the reciprocals of the loss factor (tan 5). The loss in DR (l/2 ) is the sum of the loss of dielectric materials (I/Qm). surface conduction HQ, and radiation loss (1/2,) ... 

The curves showing the frequency dependence of loss functions [tan 5, G"(g)), or / (to)] permit the detection in the frequency domain, at temperatures just slightly above the glass transition temperature, of a prominent absorption or a process. The unavailability of experimental devices to measure mechanical viscoelastic functions at high frequencies impedes the detection of a fast process or P relaxation in the high frequency region. This latter process is usually detected in the glassy state at low frequencies. 

Occasionally, networks use RS-232 cables (also known as serial cables) to carry data. The most classic example is in older mainframe and minicomputer terminal connections. Connections from the individual terminals go to a device known as a multiplexer that combines the serial connections into one connection and connects all the terminals to the host computer. This cabling system is seen less and less as a viable TAN cabling method, however, because LAN connections (like twisted-pair Ethernet) are faster, more reliable, and easier to maintain.
