Belief discrepant behavior and the bogus pipeline: Impression management or arousal attribution

Based on recent studies impression management theorists conclude that following belief discrepant behavior, persons will feign attitude change on paper measures, but report their “true” beliefs when attached to a lie detector (the bogus pipeline). A dissonance arousal explanation of these bogus pipeline results suggests that subjects may attribute their arousal to the bogus pipeline equipment instead of to dissonance and therefore may not be motivated to change their attitudes. The present study examined these competing interpretations and yielded results which support the dissonance arousal attribution explanation. Subjects who were attached to a (bogus pipeline) lie detector exhibited attitude change if given the opportunity to get accustomed to the equipment (which made attribution of arousal to the equipment less plausible), but showed no attitude change if no habituation experience was provided.

Reliability of pipelines and tubular equipment used in polyethylene production

Experience in operating polyethylene plants, and studies conducted at Irkutsk Research Institute, shows that there is need for major scientific, engineering, and planning efforts directed toward improving pipeline and tubular equipment reliability. Centralized and systematic analysis of failures, improvement in analytic methods used for designing, production with guaranteed reliability, improvement in the ease of repair, machinization of the assembly process, compilation of specifications for maintenance and repair, and the creation of reliability reserve at the manufacture stage by improving the technology, are all needed.

International risk: Six questions for the concerned executive

French President Mitterrand's decision to nationalize companies in targeted industries, President Reagan's recent ban on the sale of U.S.‐licensed pipeline equipment to Russia and losses resulting from the Iranian revolution make clear the importance of understanding the linkage between business decisions and political events. Yet many executives are unsure of how to manage a situation that not only encourages good government relations but also recognizes possible consequences of association with a controversial regime should the government be overthrown.

Equipment

Pipeline Equipment Ltd., Greatness Road, Sevenoaks, Kent TN14 5BY, announce the development of their Split‐o‐mat waste water cleaning machine to de‐contaminate wash water from paint washing plants. This new treatment system is described as a low cost method of removing paint pigment from wash water, allowing the water to be re‐used or discharged to drain. It is claimed that paint companies who are currently paying excessive charges for effluent disposal can benefit substantially from the Split‐o‐mat.

Rosenhain Centenary Conference - 1. Engineering requirements 1.2 Materials requirements for pipeline construction

A broad picture is presented of the current worldwide scene and future plans for oil and gas pipelines. Notwithstanding recent events, oil and gas consumption will continue to expand. As exploration moves into more remote areas of the world, longer and larger diameter pipelines will be required. Such areas are climatically increasingly hostile, throwing great demands on the performance of pipeline materials and equipment. The challenge to the metallurgist to produce low cost pipeline materials with the requisite levels of strength, toughness and weldability is being met. Developments in pipe steels technology which have been substantial during the past ten years will provide the basis for pipeline construction in the years ahead. The fracture behaviour of pipelines has received considerable attention in recent years. As a fracture can be inadvertently initiated by earth moving machinery, pipeline design is usually based upon demanding fracture arrest criteria. Full scale tests have led the way to the development of effective laboratory scale assessment methods which now find wide use in quality control procedures. Offshore pipelines present additional problems to the engineer. Relatively thick wall pipes are required to resist buckling stresses during laying and collapse loads during operation in deep water. Apart from problems of attaining the necessary high levels of toughness in such thick wall pipes, the requirements of offshore pipelines are unlikely to present major new challenges to the metallurgist. Overall, the principal requirements are for quality, reproducibility and reliability at reasonable cost.

Pipeline Field Welding and Quality Control Methods

Pipeline laying practice in the United States has progressed from field experience methods to recognized engineering technology. The development of pipeline procedures and practices is presented. Speed, mobility, skill and inventiveness of the pipeline men in general characterize pipeline work. Most pipeline equipment is developed in the field. Line-up clamps are an outstanding example of such equipment.

Jet Mixing of Two Liquids

Abstract The problem of mixing or blending in a tank of two or more liquids of low viscosity and the same density has been investigated in terms of available information on turbulent fluid jets discharging into a very large volume. Under the assumption that all fluid inducted into the jet is mixed completely, the effectiveness of any arrangement has been expressed in terms of a performance parameter which is defined as the gallons per minute of fluid inducted per horsepower supplied. The calculated results for a large gasoline-blending tank demonstrate the superiority of performance of the propeller-type mixer over typical jets produced with transfer-pump and pipe-line equipment. The economics of the installation and operation of equipment were not included.
