Traditionally used in cladding and insulation products, the innovative use of PUR as a thermal barrier in windows and doors gives the PURe ® range the potential to achieve U-values as low as 0.71W/m2 K when calculated as a commercial CEN standard window and 0.93W/m2 K when calculated as a CEN standard door. In 1946, the famous British economist J.R. hicks, in value and capital, developed the concept of income into a general concept of economic gain. He argues that the real purpose of computing revenues is to make people aware of the amount of money they can spend without making them poorer. Accordingly, he gave a generally accepted definition of "the maximum amount of consumption that a person can spend at the end of the term, at the same level of prosperity". Hicks's definition, though primarily for personal gain, applies to businesses as well. In the case of the enterprise, according to this definition, the enterprise income can be understood as the maximum amount that can be allocated in the enterprise cost accounting period under the same amount of capital at the end of the term and the beginning of the period. No matter what happens, Mr Trump will continue his frantic campaign to sell information, promote fake news and boast of the "biggest and best" economy of all time. In doing so, he could even create a circus worthy of the Roman emperor. But if the use of advanced words is not enough, he may decide to attack, especially internationally. This could mean a real withdrawal from nafta, trade action against China and other trading partners, or a more stringent immigration policy. Reuters quoted societe generale (601166, shares) head of U.S. rates strategy Subadra Rajappa, said over the past few sessions, is the tax factors driving bond yields and higher risk assets. And strong economic data usually drag down the bond market. Value theory of the many contradictions and arguments, essentially derives from the different definitions of value, originated in the people for the different understanding of the concept of value, value, from the perspective of physics can put the theory of value based on the foundation of natural science, with a high degree of accuracy, objectivity and rationality, so that the value theory of widespread vagueness, subjectivity and ambiguity naturally are addressed. As social things all the movement and the change of value relation is in essence the motion and change, so the value theory is the foundation of social science theory, if the value theory is built on the basis of natural science, can greatly promote the fusion and unity of the social science and natural science, but also make the social science become subservient to the natural sciences. The accounting income follows the historical cost principle and the matching principle, which is conducive to the objective reflection of the business management responsibility of the enterprise management authorities. But, due to the historical cost principle inherent defects, especially according to the present value of revenue and expenses by historical cost line, makes the calculation of accounting earnings lack of inner logical unity, and the matching principle is difficult to carry out, so that the book value of assets can not reflect its real value, cost cannot be fully compensated. And the economic benefit is measured in the current value, which reflects the actual value of the asset, which is beneficial to the full compensation of the cost.
