Food science. Upon rehydrating dried apples slices, you found that the slices did return to the original water content. What phenomenon was responsible - Essay Example Rehydration can be considered as a measure of the injury to the material caused by drying and treatments preceding dehydration (Okos et al., 1992; McMinn & Magee, 1997a). Rehydration of dried plant tissues is composed of three simultaneous processes: the imbibition of water into dried material, the swelling and the leaching of solubles (McMinn & Magee, 1997b; Lewicki, 1998). It has been shown that (Steffe & Singh, 1980) the volume changes (swelling) of biological materials are often proportional to the amount of absorbed water. Fan et al. (1962) found that the gain in volume caused by water sorption equalled the volume of imbibed water. On the other hand, the moisture-induced swelling of soybean and pigeon pea grains was always less than the volume of sorbed water (Singh & Kulshrestha, 1987). Studies of the volume increase of semolina (Bhattacharya, 1995) and soybean showed that rehydration temperature markedly affected volume increase. It is generally accepted that the degree of rehydration is dependent on the degree of cellular and structural disruption. During drying, Jayaraman et al. (1990) observed irreversible cellular rupture and dislocation, resulting in loss of integrity and hence, a dense structure of collapsed, greatly shrunken capillaries with reduced hydrophilic properties, as reflected by the inability to imbibe sufficient water to rehydrate fully. The objectives of this investigation were to test the hypothesis that a generalized model to describe the following structural properties during rehydration could be generated. The properties were true density, apparent density, porosity and specific volume of dehydrated apple, banana, potato and carrot during

The cost of capital Essay Example | Topics and Well Written Essays - 750 words

The cost of capital - Essay Example The formula determines the appropriate expected return of alternative projects. The cost of capital is the amount that the investor has to pay in order to generate a series of future dividend incomes, return of investments (Sheridian, Martin & Keown, 2010). For example, Geoff Black (2010) reiterated the business earns $1,000,000 in one year. The profits will grow by 2 percent per year, and the company generates a net worth of $16,666,667 after two years. The cost of capital is arrived at as follows:After computing the formula, X is equal to 8 percent cost of capital figure. Further, the cost of capital can include the return that the stock market investors are expected to earn from their investments in a company. The firm that generates revenues more than the amount of cost of capital will entice the company’s current and prospective investors to invest additional funds into the invested company’s coffers.For example, Microsoft generated a 53 percent return on its equit y. The company’s equity is $7.2 billion. Computing, the company’s return on equity is $3.8 Billion. If the company’s cost of capital is 14 percent, the company’s cost of capital is $1.0 Billion. The company’s residual income is $2.8 Billion. ($3.8 Billion - $ 1.0 Billion). Another term for the $2.8 Billion net income is residual income or Economic Value Added (EVA). Under the Economic Value Added (EVA), management is faced with the financial question whether the assets can be better used in other areas or by fresh management.
