United Metals has decided to launch the production of a new product‚ the firm is expecting this project to last over 8 years. The issue at hand is to know whether it would be more advantageous for United Metals to produce the components itself or to directly buy them from one of its suppliers‚ Amalgamated Components. In order to arbitrage between the “make” and “buy” decision we will calculate the Net Present Value of both these options. In order to do so we will first compute the annual cash flows

Apache Metals‚ Inc What problems can you see in the way project managers were assigned in the past? In the past‚ there are many problems in the employment of the project manager. Before any step you take the company must be well thought out before making any decision. In the past they did not have sufficient experience in decision-making and the non-existence of the staff. The main reason in the past was that they do not have the experience and they were taking the wrong decisions. Lack of

Metals & Non-Metals Metals: Good conductors of heat and electricity. Have shining luster. Malleable (this means that they can be hammered or distorted). Ductile (this means that they can be drawn into wires). Most have high melting and boiling points. Are sonorous (give out sound when beaten). Usually solid at room temperature. An exception to this is mercury‚ which is liquid in nature. Examples: Aluminum‚ Gold‚ Copper‚ Silver‚ Sodium‚ Potassium‚ Mercury. Corrode or oxidize in

Transition Metals 1a) The d-orbitals of a free transition metal atom or ion are degenerate (all have the same energy.) However‚ when transition metals form coordination complexes‚ the d-orbitals of the metal interact with the electron cloud of the ligands in such a manner that the d-orbitals become non-degenerate (not all having the same energy.) The way in which the orbitals are split into different energy levels is dependent on the geometry of the complex. Crystal field theory can be used to predict
