Contemporary life is racing against time in its temptations and variables, and it has become shaped and changed in an amazing way in its various aspects and fields. This was facilitated by intellectual and scientific communication between civilizations, and the rapid progression in successive inventions and discoveries in the fields of science and arts of knowledge. This contributed to a great economic and commercial renaissance. Then, these economic developments entered the world into a very strong competition, which forced producers to calculate all production costs, to reach the highest profits by reducing the price of the produced commodity on the one hand, and achieving quality in appearance (especially) on the other hand. Since the machine represents an important part in the production and manufacturing process, its survival and serviceability are essential to the course of production and avoiding loss. Therefore, it was imperative for project owners to provide specialists from experts and technicians to provide the required service according to the technical rules, for the operation of those tools and devices. Thus, the maintenance contract appears as one of the necessary contemporary contracts accompanying technical and economic development. The importance of this contract and the need for its presence have increased due to a number of factors, the most prominent of which are: 1. The employer's maintenance of the machines may cost him a lot, while it would not cost him much if he entrusted its maintenance to a maintenance company. This is due to the following: A- The employer's maintenance requires him to provide an integrated work team for maintenance only. These may only be needed a few times, which is not commensurate with the amount he will pay them, especially since some of them may receive a high salary because they are rare engineers, for example. B- Maintenance may sometimes require precise machines and devices, the purchase of which may cost the employer more than if he contracted with a company that appointed itself for this purpose. 2. The increased use of machines and devices to accomplish work in this era, as they have entered most fields. Means of transportation, such as cars, planes, ships and trains, require maintenance, machines in factories require maintenance, electrical devices of all kinds require maintenance, in addition to buildings and what they in turn require in terms of maintenance. 3. Maintaining production machines preserves them and keeps them away from breakdowns as much as possible. This is because the breakdown of these machines, even for a short period, may cause large and severe losses.
Background: The ideal maxillofacial prosthesis should have fine and thin boundaries that bindwith the surrounding facial structures and possess high tear strength.This study aims to determinethe best percentages of nanofiller (TiO2) and intrinsic pigment (silicone functional intrinsic) thatcould be mixed in as additives to improve the tear strength of Cosmesil M511 andVST50F siliconeelastomers with the least effect on their hardness.Materials and Methods: In this in vitro experimental study, a total of 80 samples, 40 for eachelastomer, were fabricated. Each elastomer sample was split into two equal groups to test for tearstrength and Shore A hardness. Each group consisted of 20 samples, including 10 control sampleswithout additives and 10 e

So that, banks in large choose to base the profitability measures adjusted for risks; that is we introduced this research. The most important reason led us to do this is the restriction to use the modern statistical methods by trade bank in Arab countries equally with world banks which were the antecedent to base those models. Therefore, the research problem is embedded in the banks need to use measures that link between profitability and risks and this is what achieved by RARC
