Abstract

Surfactants are important corrosion inhibitors that are used in different applications. This paper utilizes the recently developed methodology and formulae to predict mild steel corrosion inhibition by alkyl pyridinium chloride and alkyl trimethyl ammonium bromide compounds. By utilizing different surfactants of varying chain lengths in different acidic media and determining the associated corrosion inhibition, the relationship between surfactant concentration, surfactant hydrocarbon chain length, surfactant critical micelle concentration, and corrosion inhibition can be evaluated. The results from this study can be used to improve relevant industrial uses of surfactants for corrosion inhibition.

Abstract

Purpose

To evaluate mild steel corrosion using a new surfactant‐inhibition model which was derived, in part, from the concept of intermolecular energy and molecular separation distance.

Design/methodology/approach

A Gamry potentiostat was used for polarization resistance tests to determine corrosion rate and the level of adsorption of surfactant at the solution‐metal interface was determined using UV‐spectroscopy. The relationship between inhibition and surfactant adsorption as well as metal corrosion was investigated using a traditional surfactant‐inhibition model, which assumes inhibition is directly proportional to surfactant coverage and new model.

Findings

The comparison of adsorption data and corrosion inhibition data shows inhibition was not directly proportional to physical coverage as assumed by the traditional inhibition model. Instead, it was found that coverage was related to inhibition through a power‐law dependency that is similar to that used to determine molecular interaction energies.

Research limitations/implications

The new model was evaluated only for dodecyl pyridinium chloride mild steel system. The evaluation of the new model for various surfactant‐metal systems is suggested for future research.

Originality/value

The new model was found to more accurately predict the relationship between inhibition and coverage rather than traditional models for dodecyl pyridinium chloride‐mild steel system.

Abstract

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

Abstract

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

Abstract

Investigates the differences in protocols between arbitral tribunals and courts, with particular emphasis on US, Greek and English law. Gives examples of each country and its way of using the law in specific circumstances, and shows the variations therein. Sums up that arbitration is much the better way to gok as it avoids delays and expenses, plus the vexation/frustration of normal litigation. Concludes that the US and Greek constitutions and common law tradition in England appear to allow involved parties to choose their own judge, who can thus be an arbitrator. Discusses e‐commerce and speculates on this for the future.

Abstract

Through a survey of 200 employees working in five of the thirty establishments analysed in previous research about the microeconomic effects of reducing the working time (Cahier 25), the consequences on employees of such a reduction can be assessed; and relevant attitudes and aspirations better known.

Abstract

The New Year will see Britain a member of the largest multi‐national free trade area in the world and there must be few who see it as anything less than the beginning of a new era, in trade, its trends, customs and usages and especially in the field of labour, relations, mobility, practices. Much can be foreseen but to some extent it is all very unpredictable. Optimists see it as a vast market of 250 millions, with a lot of money in their pockets, waiting for British exports; others, not quite so sure, fear the movement of trade may well be in reverse and if the increasing number of great articulated motor trucks, heavily laden with food and other goods, now spilling from the Channel ports into the roads of Kent are an indication, the last could well be true. They come from faraway places, not all in the European Economic Community; from Yugoslavia and Budapest, cities of the Rhineland, from Amsterdam, Stuttgart, Mulhouse and Milano. Kent has had its invasions before, with the Legions of Claudius and in 1940 when the battle roared through the Kentish skies. Hitherto quiet villagers are now in revolt against the pre‐juggernaut invasion; they, too, fear more will come with the enlarged EEC, thundering through their one‐street communities.
