Chapter Electronic Payment systems 10.1 Traditional Electronic Payment Systems for Electronic Commerce In electronic commerce, the challenges of payment transactions were initially underestimated Business via the internet and mobile telephony has so far been dominated by the methods of payment customary in traditional business. However, in light of technological progress

he value of alkyl halides as starting materials for the preparation of variety of organic functional groups has been stressed many times. In our earlier discussions, we noted that aryl halides are normally much less reactive than alkyl halides in reactions that involve carbon-halogen bond cleavage. In the present chapter you will see that aryl halides can exhibit their own patterns of chemical reactivity, and that these reac

We are going to consider the forces exerted on a material. These can be external or internal. External forces come in two flavors: body forces(given per unit mass or volume) and surface forces(given per unit area). If we cut a body of material in equilibrium under a set of external forces along a plane as shown in fig. 1. and consider one side of it we draw two conclusions: 1 the equilibrium provided by the loads from the side taken out is provided by a set of forces that are distributed among the material particles adjacent to

SOLUTIONS TO TEXT PROBLEMS 7.1 (c)Carbon-2 is a stereogenic center in 1-bromo-2-methylbutane, as it has four different substituents: H, CH, CH,CH2, and BrCH2. H BrCH2-C-CH2CH, CH3 (d) There are no stereogenic centers in2-romo-2- me. Br CH:-C-CH,CH3 CH, 7.(b) Carbon-2 is a stereogenic center in 1, 1, 2-trimethylcyclobutane

The triacylglycerol shown in text Figure 26.2a, with an oleyl group at C-2 of the glycerol unit and two ste earyl groups at C-I and C-3, yields stearic and oleic acids in a 2 I molar ratio on hydrolysis. A constitutionally isomeric structure in which the oleyl group is attached to C-1 of glycerol would yield the same hydrolysis products

Lead-in The news that a sheep in Scotland has been successfully cloned 1) got me wondering What good would it be to clone humans? What would I do with a clone of myself? Then 2) it hit me that I could have my clone go into work for me while went out hiking, biking, sking,etc.! really could be in two places at once

In the present era of technological advances, particularly in the various imaging modalities, there is a growing conception among practicing physicians in cardiovascular medicine that bedside physical examination is unnecessary and does not provide useful information

We have thus far looked at In-plane loads torsional loads In addition, structures can carry loads by bending. The 2-D case is a plate, the simple 1-d case is a beam. Let's first review what you learned in Unified as Simple Beam Theory
