...Energy, Work and power of the body All body activities including thinking, doing work, or keeping the body temp. constant involve energy changes, for example under resting(Basal)conditions the skeletal muscles and the heart using 25% of the body's energy ,another 19%is being used by the brain,10%is being used by the kidneys, and 27% is being used by the liver and the spleen. A small percent of about 5% of food energy being excreted in feces and urine. Extra food energy will be stored mainly as fat. External heat energy from environment can help maintain the body temp. , but it has no use in body function. Conservation of energy Change in the stored energy (i.e. food energy, body fat and the body heat) =Heat lost from the body + Work done Assumes that no food or drink is taken and no feces or urine is excreted during the interval of time considered. ●This is similar to the first law of thermodynamic:- ∆Q= ∆u + ∆w -1- ●Where ∆Q is the change of quantity of heat of the system. ● ● ∆u is the change in the internal or stored energy. ∆w is the work done. This can be written as ∆u= ∆Q - ∆w A body doing no work (∆w=0) and at constant temp. continues to lose heat to its surroundings, and ∆Q is negative. Therefore, ∆u is also negative, indicating a decrease in stored energy. The rate of change of their variables is just taken per unit time ( by dividing on ∆t) . ∆u / ∆t = ∆Q/∆t - ∆w/∆t The body's basic source of energy is the food energy; it must be chemically changed...

...employers are laying off full-time workers, many are also trying to compensate by turning over some of the work to temp staff. Ironi cally, of course, many of those who've been laid off are highly qualified, and as they hit the job market willing to accept lower-level positions, the ranks of job hunters are being joined by a substantial number of highly qualified (which is to say, overqualified) workers. “The quality of candidates,” says Laura Long of Banner Personnel, a Chicago-area staffing agency, “is tremendous…. As an employer, you can get great employees for a great price.” As a matter of fact, if you're a U.S. employer, you've always been able to get temp workers at a relatively good price. As of December 2010, according to the BLS, the average cost of a full-time worker in private industry was $22.26 per hour in wages plus $9.75 in benefits, for a total of $32.01 in compensation. By contrast, the average wages for a temp were $12.14 and the average benefits were $3.42, for total compensation of $15.56. One of the results of this cost differential has been a long-term increase in the number of temp workers which, over the last 20 years, has far outstripped the increase in jobs occupied by full-time workers. Case Questions 1. You're a senior manager at a growing business and you're ready to add employees. Your HR manager has recommended a temp-to-perm policy. You know the advantages of this approach, but what might be some of the disadvantages? 2. Assume...

...the heat absorbed (per mole of specified reactant or product) when the reaction occurs at constant pressure (chemistry textbook). By ‘change in enthalpy’ it means the increase in enthalpy going from reactants to products. The heat released is a direct measure of ΔH. ΔH is sometimes referred to as the heat of reaction. The enthalpy change for a reaction, ΔH, will be the energy required to break the necessary bonds in reactant molecules minus the energy released when the new bonds are formed. ΔH= energy to break (bonds in reactants) – energy to make (bonds in products). To calculate the heat released or absorbed the formula generally used is the q = m CΔ T (refer to appendix B for the general procedure). This formula is also used when calculating quantities of heat. The symbol (q) is to denote the quantity of heat (J) measured in joules. The amount of heat energy is different to temperature; for example, two objects can be at the same temperature but contain very different amounts of heat. This is because the amount of heat energy is proportional to the mass of the substance involved and also the amount of heat energy contained in equal masses of different substances depends upon the nature of the substances involved. Which then leads to (C) ‘specific heat capacity’, of a substance is the amount of heat required to raise the temperature of unit mass of the substance by 1ᴼC (or through 1 kelvin). Specific heat capacity is therefore measured in joules per kelvin per gram, J K–1 g–1...

What is the required rate of return on the firm’s stock? Using SML to calculate temp force’s required rate of return: rs = rRF + (rM – rRF)bTemp Force = 7% + (12% - 7%)(1.2) = 7% + (5%)(1.2) = 7% + 6% = 13%. D) Assume that Temp Force is a constant growth company whose last dividend (D0, which was paid yesterday) was $2.00, and whose dividend is expected to grow indefinitely at a 6 percent rate ? 1) What is the firm’s expected dividend stream over the next 3 years? Temp Force is a constant growth stock, and its dividend is expected to grow at a constant rate of 6 percent per year.

...The national economy is sluggish and for businesses to continue moving forward it is imperative that they continue producing at an acceptable rate without incurring many additional costs. One of the chief components to success in this venture is employee attendance. The employee absenteeism can cost the company funds from an already tight budget by way of lost manpower, or hiring temps. Temps generally are not going to be as fast as the employee because they have not been acclimated to the system at the company and if a temp is not brought in the missing employee slows the work schedule regardless of the position the employee holds. The arguments about what causes employee absenteeism abound worldwide but the bottom line still equals dollars and cents. Recently there have been movements to create an atmosphere from which employees do not want to stay home from. Caregiver centers for children, buy back programs for sick days and many other avenues are being tried. Until businesses can determine the cause of absenteeism that is not illness related and find solutions they will continue to lose money. At the end of the last decade the employee absenteeism rate was lower than it had been in a decade. Many believe that family leave issues and personal leave problems had been dealt with in a successful manner and the problem was solved(Employee, 1997). Since that time however absences in the workplace have continued to plague business around the world including in the United States...
