The aim of this work is to study the corrosion and scaling factors, mechanisms and processes affecting the materials, equipment and installations of the Cerro Prieto geothermal field (GTF).
The physicochemical characteristics of the geothermal well and fluids were analysed, recorded and related to the corrosion and scaling phenomena.
The high temperature and salinity of the steam‐brine mixture and the presence of hydrogen sulphide and carbon dioxide impart a severe level of corrosivity.
Corrosion and scaling control assure an efficient production regime, provide for the durability of the GTF engineering materials and equipment and contribute to environmental quality.

Microbiologically induced corrosion of copper intrauterine devices “TCu380A” and “Nova T” by Enterobacter sp. in a synthetic intrauterine medium was investigated. The corrosion behaviour was evaluated applying cyclic voltammetry and Tafel Polarization. The surface morphology was determined using scanning electron microscopy, the corrosion products were analyzed using energy dispersive X‐rays and the biofilm composition was examined by Fourier transform infrared spectroscopy with an attenuated total reflectance device.

This research aims to analyze the potential of revenue management in the German car industry. The concept offers the chance for original equipment manufacturers (OEMs) to be more customer‐oriented to reduce costs and increase earnings. To implement revenue management, criteria are required to segment the customers. The car configuration changes and the delivery time look suitable in this context and this paper aims to analyze these.
Survey analysis was conducted with 2974 German buyers of new cars. The respondents recently bought a car or were in the planning process of doing so. A total of 803 data sets could be evaluated statistically using SPSS software. Descriptive statistics and mean test were utilized to test several hypotheses and find out distinctions between the respondents.
The results show that German car buyers could be segmented in to different groups according to the criteria: delivery time and configuration changes. This enables manufacturers to introduce revenue management and realize benefits in better customer orientation and improved supply chain planning.
This research shows that German OEMs, especially the premium OEMs overestimate the value of change flexibility and short delivery times for their customers. The implementation of revenue management could help to reduce complexity and offer each customer the appropriate degree of change flexibility and the optimal delivery time combined with a process‐ and effort‐adequate pricing.

Historically, Panama has always been “a place of transit.” While technically the isthmus formed part of Colombia in the nineteenth century, it was linked geopolitically to the United States soon after the California gold rush, beginning in the late 1840s. The first attempt at building a canal ended in failure in 1893 when disease and poor management forced Ferdinand de Lesseps to abandon the project. The U.S. undertaking to build the canal could only begin after Panama declared itself free and broke away from Colombia in 1903, with the support of the United States.

The cardinal point to note here is that the development (and unfortunately the likely potential) of area policy is intimately related to the actual character of British social policy. Whilst area policy has been strongly influenced by Pigou's welfare economics, by the rise of scientific management in the delivery of social services (cf Jaques 1976; Whittington and Bellamy 1979), by the accompanying development of operational analyses and by the creation of social economics (see Pigou 1938; Sandford 1977), social policy continues to be enmeshed with the flavours of Benthamite utilitatianism and Social Darwinism (see, above all, the Beveridge Report 1942; Booth 1889; Rowntree 1922, 1946; Webb 1926). Consequently, for their entire history area policies have been coloured by the principles of a national minimum for the many and giving poorer areas a hand up, rather than a hand out. The preceived need to save money (C.S.E. State Apparatus and Expenditure Group 1979; Klein 1974) and the (supposed) ennobling effects of self help have been the twin marching orders for area policy for decades. Private industry is inadvertently called upon to plug the resulting gaps in public provision. The conjunction of a reluctant state and a meandering private sector has fashioned the decaying urban areas of today. Whilst a large degree of party politics and commitment has characterised the general debate over the removal of poverty (Holman 1973; MacGregor 1981), this has for the most part bypassed the ‘marginal’ poorer areas (cf Green forthcoming). Their inhabitants are not usually numerically significant enough to sway general, party policies (cf Boulding 1967) and the problems of most notably the inner cities has been underplayed.

The following classified, annotated list of titles is intended to provide reference librarians with a current checklist of new reference books, and is designed to supplement the RSR review column, “Recent Reference Books,” by Frances Neel Cheney. “Reference Books in Print” includes all additional books received prior to the inclusion deadline established for this issue. Appearance in this column does not preclude a later review in RSR. Publishers are urged to send a copy of all new reference books directly to RSR as soon as published, for immediate listing in “Reference Books in Print.” Reference books with imprints older than two years will not be included (with the exception of current reprints or older books newly acquired for distribution by another publisher). The column shall also occasionally include library science or other library related publications of other than a reference character.

The conflict between Iran and Iraq is not new; it dates from long before September 1980. In fact, the origins of the current war can be traced to the battle of Qadisiyah in Southern Iraq in 637 A.D., a battle in which the Arab armies of General Sa'd ibn Abi Waqqas decisively defeated the Persian army. In victory, the Arab armies extended Islam east of the Zagros Mountains to Iran. In defeat, the Persian Empire began a steady decline that lasted until the sixteenth century. However, since the beginning of that century, Persia has occupied Iraq three times: 1508–1514, 1529–1543, and 1623–1638. Boundary disputes, specifically over the Shatt al‐Arab Waterway, and old enmities caused the wars. In 1735, belligerent Iranian naval forces entered the Shatt al‐Arab but subsequently withdrew. Twenty years later, Iranians occupied the city of Sulimaniah and threatened to occupy the neighboring countries of Bahrain and Kuwait. In 1847, Iran dominated the eastern bank of the Shatt al‐Arab and occupied Mohamarah in Iraq.
