Rational use of fuels and lubricants, energy efficiency, environmental safety are included into the list of the most important problems of the modern world. Solving these problems determines in a great manner the sustainable development of the world economy and keeping comfort conditions for human being. Efficiency, reliability of operation of vehicles, rational use of operational materials depend on their correct selection. According to its quality operational materials must conform to both the model and operating conditions of vehicles. The use of poor quality materials leads to a decrease in the durability and reliability of machinery and machine parts; the use of materials of higher quality than required causes unreasonable increase in costs. The knowledge of machinery suggest not only the knowledge of construction, kinematic, dynamic, and temperature characteristics but also physico-chemical properties of constituent materials that are necessary for analyzing and forecasting of physico-chemical processes during use of a Fuels or a Lubricants. Thus, the efficiency and reliability of vehicles operation depends not only on their structural characteristics, but also on the optimal selection of Fuels and Lubricants, Technical Liquids and other Operational Materials. Work professional activity of specialists dedicated to petroleum refinery, organizing of storage, transportation and distribution of products, assurance of correspondence between the properties of Fuels, Lubricants, Technical liquids and the conditions of operation of technology and engines aimed at obtaining maximum technical, economical, ecological and social effects is called usage of Fuels, Lubricants and Technical liquids. To know Fuels, Lubricants and Technical liquids is to clearly understand the interconnection of quality parameters with physico-chemical and energy processes, occurring in the process of their use under specific conditions, and also the connection with their chemical and group composition. The knowledge of technology suggest not only the knowledge of construction, kinematic, dynamic, and temperature characteristics but also physico-chemical properties of constituent materials that are necessary for analyzing and forecasting of physico-chemical processes during use of a Fuel or a Lubricant. The study of the essence, regularity (tendens) and connections of phenomena and the processes of use of Fuels, Lubricants, Technical liquids in Aviation Technology with the help of special methodological tools is the base of Aviation Chemmotology. Aviation Chemmotology is a part of Chemmotology that studies and solves the problems of ensuring the necessary quality and application requirements of Fuels and Lubricants used in Aviation Technology. Chemmotological reliability is a reliability of technology depending on the Quality of Fuels and Lubricants (the ability of technology to maintain good reliability when operated with Fuels and Lubricants grades that are of a economically reasonable quality level). This monograph as an intergative scientific work of many scholars is a striking example of the representation of these aspects and really illustrates the modern consolidated work of scientists and practitioners, trends in the development of scientific schools of different universities, different countries and science in general. Because, as is know, science does not have borders. Scientific achievements are global civilizational heritage. 4 Chapter 1 THEORETICAL ASPECTS OF CHEMMOTOLOGY, CHEMICAL TECHNOLOGY AND ENGINEERING DOI: doi.org/10.18372/38235 UDC: 547.912.66+665.7.038.64+665.65 1.1 THE PROBLEMS OF FORMATION OF ASPHALT-RESIN-PARAFFIN DEPOSITS. PREVENTION AND UTILIZATION Olena Tertyshna, Kostiantyn Zamikula, Oleh Tertyshnyi Oil dispersed systems (ODS) contain asphaltenes, resins and paraffins which can promote the formation of asphalt-resin-paraffin deposits (ARPD) on the surfaces of process equipment. The rate of deposits formation is influenced by the oil composition, namely, the ratio of paraffins, resins and asphaltenes, and by the hydrodynamic and temperature conditions of its transportation, storage and processing [1]. Asphaltenes, peptized and stabilized by resins, are characterized by high melting points (300 оC) and are partly in the solid state in oil. They do not form a joint crystals or solid solutions with hydrocarbons, and serve only as centers of aggregation and crystallization. Resins in oil form true solutions and are located in the dispersion medium. Part of the resin, the pour point of which is close to the pour point of hydrocarbons, crystallizes forming mixed crystals or solid solutions. The other part forms the solvate shell around the solid particles. Asphaltenes behave as coagulants, resins – like peptizers, preventing the merging of crystals and the formation of spatial grid [1]. ARPD formation and growth are promoted by the temperature gradient which occurs in the near-wall layer of pipeline and heat exchangers as a result of raw material cooling. Typically, deposits are removed without prior analysis of the reasons of their formation and accumulation in various units of industrial equipment [2]. The creation of a well-founded kinetic model of ARPD formation and growth will allow to develop ways of deposition minimization, and in the future it will allow to prevent their formation. The kinetics of deposits formation from oil sample, which was taken from the storage tank at the refinery, was investigated. Oil characteristics of the content of potentially solid components are presented in Table 1. ARPD formation was studied using a method of «coldfinger test». A glass of oil (200 ml) was placed in a thermostatic bath, where with stirring at a speed of 120 Rev/min it was heated to the temperature of 30, 40 and 50 оC. The copper tube («coldfinger») with the surface of 744.45 mm2 was cooled with running water to a temperature of 10 оC. Preliminarily weighed and degreased tube was placed in the center of the glass with

    The Building of an Oliver Five-String Fiddle © Chet Bishop, Luthier i ii Foreword Credits: Credit to Those Who Contributed: First, I want to give thanks for my wonderful wife, Ann, who offered her love, patience, support, and faith, believing that the things I have attempted were worth doing. Second, for my friend Jake Jelley, who saw in me the potential; the “raw materials” necessary to become a luthier. He gave time, materials, tools, books, and unfailingly friendly support and encouragement. Finally, for a host of teachers, some now dead, some still alive: Some have made it clear they do not want to be named, so I will comply with their wishes. Nevertheless: if you are one of my teachers, and find yourself alluded to in these lines, please know that I do appreciate you and deeply respect your expertise. I especially appreciate your kind attention and patience as you helped me to learn to see, and to bring my dreams to fruition. To those who have passed on: I sincerely wish you were here to share my joy. Disclaimer: “Descriptive, not Prescriptive” When I was in school, a writing professor made a point of distinguishing the several types of analyses available in Technical Writing: If I were writing a user’s manual, directions for assembly, a building code, or something similar, then a prescriptive analysis would be appropriate. But since I am writing a report of something that actually happened, description is the appropriate thing. I am telling no one what they should do. Further, a description can be either formal or informal, in varying degrees.

Development and Evaluation of Stanford/Ames EVA Prehensors SUMMARY Space Station operations and maintenance are expected to make unprecedented demands on astronaut Extra-Vehicular Activity (EVA). With the Space Station expected to operate with a 8-10 psi atmosphere (versus 4 psi for Shuttle operations), the effectiveness of pressurized gloves is called into doubt at the same time that EVA activity levels must be increased. To address the need for more frequent and more complex EVA missions and also to extend the dexterity, duration and safety of EVA astronauts, NASA-Ames Research Center and Stanford University have an ongoing cooperative agreement to explore and compare alternative solutions. Nearing completion toward this objective is the initial development of a series of Stanford/Ames manually-powered EVA Prehensors. Each prehensor consists of a shroud forming a pressure enclosure around the astronaut’s hand, and a linkage system to transfer the motions and forces of the hand to mechanical digits connected to the shroud.

It takes place in the Outer Banks of North Carolina in 1910 and imagines the perspective of a sound-color synesthete named Bert Beasley, who witnessed the Wright brothers complete the first engine-powered flight. Bert wants to leave his home to pursue aviation but is unable to do so because he is needed to help run his family's failing general store. When Elisabeth Lavoie, a French musician, moves to town and buys a dilapidated house, Bert believes he'll be able to solve his problems by earning extra money as her repairman. However, her voice is purple—the only color he's never heard before—and her music changes colors, which shouldn't be possible. As he grows closer to Elisabeth, Bert becomes less sure that he wants to leave, but his decision is complicated once more when he learns that the Wright brothers have opened a flying school.

Just as most of you do research on the web before phoning to place an order, and many of you call to discuss your purchase with a salesperson before ordering on the web, the catalog is a complementary source of information to help you explore and fulfill your lutherie needs so you can order intelligently. You can flip through the pages at random, hold 3 spots open simultaneously with your fingers, and use it in rooms where the phone and web are just not as comfortable! Times have changed and they continue to change quickly. So even as we improve and expand our catalog, we realize we are no longer a catalog company!
