Nanotechnology - Assignment Example In the 1980s, K. Eric Drexler popularized the word nanotechnology by talking about building machines on the scale of molecules like robot arms, motors, and even computers into those far smaller than a cell. In the traditional sense, nanotechnology means building things from the bottom up, with an atomic precision. This theoretical ability was envisioned in the early 1959 by the renowned physicist,  Richard Feynman. A layman’s understanding of nanotechnology has evolved considerably since the progression of mainstream films like Star Wars and Science Channel documentaries, whereas before, these concepts were little known to the public and were considered to be of science fiction and in the far distant future (Johnson 103). It represents the manufacturing system which has the ability to make enough manufacturing systems implying factories can be built rapidly, cleanly and cheaply. This enables means of production to reproduce exponentially, so that in just a few weeks few nanofactories conceivably can become  billions. Nanotechnology offers great potential for benefit to humankind, and also brings severe dangers. While it is appropriate to examine carefully the risks and possible toxicity of nanoparticles and other products of nanoscale technology, the greatest hazards are posed by malicious or unwise use of molecular manufacturing. CRNs focus is on designing and promoting mechanisms for safe development and administration of MM effectively. This technology is suspected to cause cancer. Nanoparticles are tiny enough to penetrate cell membranes and defenses and they are able to cause problems by interfering with normal cell processes. Researchers at the University of Massachusetts record that such nan oparticles are presently in use in cosmetics, electronics, and chemical manufacturing, and others industries. Pacheco and her colleagues examined how two different types of nanoparticles could damage DNA in the MCF-7 line of the breast cancer cells.

CAPM & DCFM Essay Example | Topics and Well Written Essays - 500 words

CAPM & DCFM - Essay Example the time value of the money. The more the investment is held, the higher would be the return required by an investor as money loses its value over time (Fama, 2004). The Discounted Cash Flow (DCF) method on the other hand is a method that is used in order to ascertain the charm of any particular investment. The DCF technique uses cash basis rather than accounting valuation techniques in order to analyze the attractiveness of any particular investment. Hence it considered less subjective because of its cash flow techniques. The cash flows that would be gained from any particular project are discounted using an appropriate discount rate based upon the market rate and the investor’s expectations in order to reflect the time value of money. If the value deduced after discounting i.e. the present value is greater than the outflows (usually required at the current time horizon), the project is accepted (Kaplan, 1994). The CAPM is used to calculate the required return of an investor. This required return is then used as a basis for the DCF method in order to ascertain the Present Value of any given project/investment. The CAPM is used in order to calculate the discount rate and this discount rate is further used within the DCF technique in order to value an investment or an asset. The CAPM uses the risk free rate in order to reflect the time value of the money. The market risk premium (i.e. the expected return rate within the market less the risk free rate) is multiplied with the relevant project beta; this project beta denotes the investor’s risk (Eugene et al, 2011; Kaplan, 1994). Usually, companies use the CAPM to ascertain the cost of equity. This cost of equity is further used to calculate the Weighted Average Cost of Capital (WACC) of a firm and finally this WACC is used within the DCF technique in order to calculate the Net Present Value (NPV) of a project/investment. The WACC within the NPV technique denotes the required
