hay day profit It is proposed to set up big core technology in the big fund It is not obvious in some analyses, but it is important to note that economic profits include opportunity costs. The profit of an entrepreneur (normal profit) is usually positive, but economic profit can be either positive or negative (loss). That's why the opportunity cost is included: in a completely competitive market, when marginal cost equals marginal revenue, profit maximization or loss minimization conditions arise. If the market price is lower than the total average cost, which means that the economic profit is negative, the entrepreneur needs to compare the value of the loss and the average variable cost. If the business continues to operate, the negative economic profit must not be lower than the average variable cost, otherwise the entrepreneur would rather shut down the company than continue to take the loss. Advertisement The bank of England says Britain is a European banker, and the imf welcomes the progress of Brexit - and that's what happened Think the dissipative structure theory, the negative entropy is to maintain and develop dissipative structure in the process of ordering "power", only the negative entropy flow to the system input, to offset the internal entropy, generated by the block system to the direction of a disorderly change, in order to maintain and develop ordering movement of the system. Obviously, this view only looks at the ordering process of dissipative structure from the perspective of pure "energy exchange". However, the nature of the material in addition to the energy the most basic characteristics, but also has many other features, such as physical properties, chemical properties and biological characteristic, social characteristic, the information characteristics, the material properties of the energy as long as the organization and cooperate well, can be used to promote the human survival and development, to maintain and develop human ordering, played the same energy orderization and objectively, and can according to the main body of the objective need of ordering energy converted into a number of standards, the dissipative structure of the ordering process is not only determined by the energy exchange, must also be by "material exchange" and "information exchange". It can be seen that some non-energy forms of the generalized preordering energy can be attached to the ordering energy and indirectly affect the preordering degree of the dissipative structure. Cave although not directly provide food for animals, for example, energy, but it can be for animals from the cold in winter, make animals reduce body heat loss, and reduce the disease incidence and mortality of animals, the objective effect and reduce the loss of food energy, improve the body of food energy use efficiency. Obviously, these not energy in the form of "ordering energy" from the objective effect does play a orderization and energy is exactly the same effect, also can promote the development of the dissipative structure ordering, plays an alternative on features, compensation, strengthen, catalytic, extension, ordering the role of energy, is a kind of indirect power energy. On the basis of "dissipative structure theory", the concept of unified axiology is put forward. 2. P45 forms are in four parts, part 1 is retained with the issuing employer and the employee retains part 1 A and may hand parts 2 and 3 for the new employer. The new employer cannot make use of the P45 tax details unless both parts are given over. If either part 2 or 3 with the P45 form is missing then this employee must be asked to complete the Inland Revenue P46 form.
