    Hydrogen Fuel Cell Cars: Worth the Investment? Hydrogen is the most abundant element in the universe‚ but only recently have people been able to harness this resource and turn it into energy. Hydrogen fuel cell cars are one such advancement made in the effort to turn hydrogen gas into electricity. Fuel cells in the car are used to convert hydrogen into an electrical current‚ and thus power the vehicle. Fuel cells convert hydrogen and oxygen into water while producing electricity. Hydrogen fuel

    CHAPTER 3 Valuing Bonds Answers to Problem Sets 1. a. Does not change b. Price falls c. Yield rises. 2. a. If the coupon rate is higher than the yield‚ then investors must be expecting a decline in the capital value of the bond over its remaining life. Thus‚ the bond’s price must be greater than its face value. b. Conversely‚ if the yield is greater than the coupon‚ the price will be below face value and it will rise over the remaining life of the bond.   3. The

    reflects the strength of forces between molecules. The more tightly bonded the molecules are‚ the more energy is required to convert them into gases. These forces are called intermolecular forces. There are 3 types‚ dispersion forces‚ dipole-dipole and hydrogen bonding. The influence of these attractive forces will depend on the functional groups present. For example heptane has boiling point of 98.4 degrees (1) and 1-hexanol has boiling point of 157 degrees. (2) The fact that heptane has lower boiling

Finally six structurally diverse compounds BTB01875‚ BTB09994‚ BTB14527‚ BTB14784‚ Compound 2479 and BTB06317 with high GOLD score and binding energy for crystal structures of KIF11 were selected. It showed hydrogen bond interaction with Tyr104‚ Tyr352 and Asn289 with important active site residues similar to that of BI8 inhibitor. These results are quite consistent with the docking analysis which illustrates the participation of these six hit compounds; BTB06317
