Specific absorption rate

INTRODUCTION Millimeter wave therapy is the exposure to a frequency that ranges from 30-300 GHz. This frequency is located in the radio frequency region of the electromagnetic spectrum. Due to the extremely small wavelength the frequency will only penetrate up to 2 mm of skin. In therapy the frequency is irradiated on certain parts of the tissue, depending on the specific treatment and energy it is deposited in the skin causing a variety of beneficial reactions. In the Former Soviet Union (FSU), this technique has been used for over 40 years on a variety of diseases; this idea then spread to other countries such as France, Germany, and Canada[1]. Since the therapeutic potential for millimeter waves ranges over such a broad variety of diseases, it is categorized in three main groups; 1) sedative and analgesic effects, 2) anti-inflammatory and repair-stimulation, and 3) immune system stimulation. The most common is the sedative and analgesic effect that millimeter wave irradiation can provide. It is considered to be a promising alternative and complement to conventional pain relief [2]. Overall, the objective of this paper is to provide information about the sedative and analgesic effect that millimeter wave therapy provides. BACKGROUND Therapeutic use of the millimeter wave band was…

The question is, “Which paper towel brand is the most absorbent?” The hypothesis is, “If a dropper drops water equally on a paper towel of each brand until it started to drip, then Bounty brand would contain the most water, in grams. The independent variable is the brands of paper towels. The dependent variable is the grams of water that was contained in the paper towel. The control variable was that every paper towel sheet was cut to be 15.2 centimeters by 28.1 centimeters. The control group…

The purpose of the Determining Food Dye Content Lab was to identify the food dye coloring in green apple Gatorade, and determine the dye’s concentration to ultimately recreate a solution containing the same concentration of dyes as the original. To determine the concentration of the dyes present in the green apple Gatorade, a spectrometer was used to measure the wavelengths and absorbance values for the given dyes. A sample of the green apple Gatorade was tested in the spectrometer to measure…

by the chlorophyll molecules (Merzlyak, Chivkunova, Zhigalova, & Naqvi 2009). These chlorophyll molecules then transfer the light energy to chloroplasts and that light energy is converted into chemical energy (Merzlyak, Chivkunova, Zhigalova, & Naqvi 2009). The purpose of this experiment was to observe what the absorbance spectrum of Spinacia oleracea extract was and what the absorbance spectrum of the pigments were within the extract. From the use of the spectrophotometer I was able record…

purpose of this lab was to show the different absorption and emission rates of three different substances. Radiation laws, albedo, and specific heat are all reasons why this is achievable. An agreed upon hypothesis is that the sand will absorb the most heat due to the number of molecules, the moss will absorb the second most because it doesn't have as many molecules as sand, but it has more than water, which isn’t as complex. To complete this experiment, you need three beakers of each material,…

The optical bandgap (EQD) can be assessed using Tauc Relation equation (2). (αhυ)2 = f(R) hυ = B (hυ - EQD )n (2) where B is proportional constant (often negligible), hv is photon energy, EQD is bandgap energy, n based on the transition type (n = 1/2 for direct allowed transitions), and α is absorption coefficient. Kubelka-Munk Equation (3): approximation of α .5 …

Among all the tested diamond films, friction tests suggest that the boron doped diamond films exhibit the lowest friction coefficient and wear rate, because of its diamond grain refinement effect. A lower friction coefficient is found in boron-doped diamond films than that of undoped ones. No variation of the total volume wear rate as a function of time was evidenced during the test since the vertical movement was negligible, a few micrometers at the end of the test. At this point, the final…

13. IT and equipment 13.1 Business premises Tara Restaurant business premises ought to meet the desired requirements. It need to has all centers that 's obligatory in line with food Act 2014, for meals premises. Enough parking areas, hygienic vicinity, properly ready, energy rating, noise and different pollutions standards ought to be as in step with the norms for the enterprise premises. 13.1.2 IT Requirements We should maintain our premises ready with unfastened wifi area to mitigate global…

the same volume is poured into four 250 ml beakers labelled pH 4.5, pH 5 and pH 5.5 as shown in figure 6. The pH of the four different solutions is adjusted to match the pH labelled on the glass. Clear hydrogen peroxide is added in a 9:1 volume ratio. On commencement of the reaction, pH measurements were taken every second until completion. This procedure is then repeated at lower molar concentration. The temperature of the reacting mixture varied between 19oC and 20oC. Figure 10: pH…

Barclays is a financial institution guilty of fraudulent activity, including misrepresentation of interbank borrowings as well as reporting incredulously low rates to allow the perception of financial health. Many banks were involved and colluding in these practices, therefore one can certainly conclude that the problem does not lie solely with the panel banks but the financial system and its governing regulators as well. LIBOR stands for London Interbank Offered Rate; it was intended to be a…
