  • Fig. 21.50 Chart for determining optimal film thickness. (From Ref. 28.) (a) Grooved member rotating, (b) Smooth member rotating. 6. Calculate R1 = { AcP0 }112 hr [3T7K - Co0)[I - (K2/*,)2]] If R1Ih,. 10,000 (or whatever preassigned radius-to-clearance ratio), a larger bearing or higher speed is required. Return to step 2. If these changes cannot be made, an externally pressurized bearing must be used. 7. Having established what ar and Ac should be, obtain values of K00, Q, and T from Figs. 21.62, 21.63, and 21.64, respectively. From Eqs. (21.29), (21.30), and (21.

  • The corporate world is living through some interesting and challenging times. In today’s world, in order to survive or remain competitive, corporations must continue to assess their organizational strategies, structures, and practices. Changing and adapting to external pressures and market shifts is now (and will continue to be) an imperative. It is a must; survival depends on it.

  • War, war, war. For me the beginning of the war was a torchlight tattoo on Salisbury Plain. It was held on one of those breathless evenings in July when the peace of Europe was trembling in the balance, and when most of us had a heartache in case--in case England, at this time of internal crisis, did not rise to the supreme sacrifice. It was just the night for a tattoo--dark and warm and still. Away across the plain a sea of mist was rolling, cutting us off from the outside world, and only a few pale stars lighted our stage from above. The field...

  • The presentation of essential data concerning vitamines to succeeding groups of students has become increasingly difficult with the development of research in this field. The literature itself has assumed a bulk that precludes sending the student to original sources except in those instances when they are themselves to become investigators. The demand on the part of the layman for concise information about the new food factors is increasing and worthy of attention.

  • To generate noise from gears the primary cause must be a force variation which generates a vibration (in the components), which is then transmitted to the surrounding structure. It is only when the vibration excites external panels that airborne noise is produced. Inside a normal sealed gearbox there are high noise levels but this does not usually matter since the air pressure fluctuations are not powerful enough to excite the gearcase significantly.

  • This suggests that a joint designed to the above equation might have larger and/or more numerous bolts than necessary to support pressure loads the bolts will never see. The ASME Boiler and Pressure Vessel Code takes an even more conservative point of view than that described by the above equation to introduce a factor of safety. This code assumes that the bolts see 100% of external load Lx, not an amount reduced by the stiffness ratio. 35.9 EVALUATION OF SLIP CHARACTERISTICS A slip-resistant joint is one that has a low probability of slip at any time during the life of...

  • Physical measurement dimensions, such as temperature or pressure and tensile forces, can affect glass fibres and locally change the characteristics of light transmission in the fibre. As a result of the damping of the light in the quartz glass fibres through scattering, the location of an external physical effect can be determined so that the optical fibre can be employed as a linear sensor. Light scattering, also known as Raman scattering, occurs in the optical fibre.

  • Contemporary organizations face constant pressure to enhance levels of service and productivity whilst also improving levels of cost efficiency. The volatility of external environment and the rapid pace of technological change increasingly demand innovative means of improving business performance and securing competitive advantage. Human resources (HR) are increasingly recognized as the prime source of competitive advantage and the need for effective people management is therefore more important than ever before....

  • In response to various pressures, businesses have begun to report externally on their environmental policy and performance. The significance of such external reporting depends on the extent of changes in management culture and systems and on how new measures influence management decisions. The 'greening of accountancy' involves a reappraisal of how to identify and measure the relevant costs of processes and products (such as 'Total Cost Assessment') and a redesign of incentive mechanisms.

  • PLANT CELLS ARE SEPARATED from their environment by a plasma membrane that is only two lipid molecules thick. This thin layer separates a relatively constant internal environment from highly variable external surroundings. In addition to forming a hydrophobic barrier to diffusion, the membrane must facilitate and continuously regulate the inward and outward traffic of selected molecules and ions as the cell takes up nutrients, exports wastes, and regulates its turgor pressure.

  • Acoustic fatigue is due to a very high intensity excitation as a result of pressure waves caused by either engine or aerodynamic effects. Acoustically-induced cracking has occurred on the external surface of the lower nacelle and aft fuselage skins on the F/A-18, as illustrated in Figure 19.1. In the former region, overall sound pressure levels greater than 170dB have been measured in flight [l]. These high sound pressure levels appear to be a result of an aerodynamic disturbance at the inlet lip....

  • The basic physics of sound propagation are simple, but the interaction of sound pressure waves with complex shapes and multi-layer constructions with openings, as you find in buildings, is more challenging. Controlling noise, both from the internal and external environment and from the internal mechanical and electrical services in buildings, is essential to create environments that promote aural communication and comfortable working conditions.

  • One authorized urologist (M.M.) performed all the operations. We used a standard TURP setup with an irrigation pressure of 80 cmH2O and an irrigation rate of 250 ml/min using D-sorbitol solution. After a rough resection of almost all the transition and central zone, we tried to resect and fulgurate the peripheral zone as completely as possible, especially where cancer was detected by biopsy. The resection was continued until adipose tissue, venous sinus or the external sphincter was identified.

  • This guide stresses the need for an effective security testing program within federal agencies. Testing serves several purposes. One, no matter how well a given system may have been developed, the nature of today’s complex systems with large volumes of code, complex internal interactions, interoperability with uncertain external components, unknown interdependencies coupled with vendor cost and schedule pressures, means that exploitable flaws will always be present or surface over time.

  • Facing pressure from shareholders, regulators, and economic forces and also seeking to improve the performance of corporate boards, US companies came up with a solution to corporate governance and leadership issues with the concept of a lead director. Since its inception, the lead director role has grown in importance and influence. A lead director is particularly helpful in focusing the board’s talent and wisdom when difficult situations arise: management performance and succession, risk management, mergers and acquisitions, and a host of other internal and external matters.
