Environmental and Industrial Corrosion

Nowadays, it is generally accepted that in the natural and industrial environments, corrosion and pollution are interrelated harmful processes since many water, air and soil pollutants accelerate corrosion, and corrosion products such as rust, oxides and salts, also pollute water bodies at ports, rivers, dams, canals and shipyards. Both are pernicious processes that impair the durability of the infrastructure assets, the industry efficiency and profitability and the quality of the environment. Therefore, it is essential to develop and to apply corrosion engineering control methods and techniques, in particular those being environment-friendly. In this crucial time of worldwide energy crisis and economic turmoil, cost effective corrosion control will extend the life of the infrastructure saving large expenses in materials, equipment and structures. This book will contribute to achieve this important mission

Bacteria and the small intestine in man

The extent of the colonization by bacteria of the small intestine of man in health and disease has for many years been a source of speculation and several investigations have been carried out in which sampling tubes have been passed by mouth (Kendal et al. 1927; Davidson and Gulland, 1930; Nicols and Glenn, 1940; 011eros, 1942; Milanes et al. 194.6; Girdwood, 1950; Howie et al. 1953; Duncan et al. 1954.; Nadel and Gardner, 1956; Martini et al. 1957; Anderson and Langford, 1958; Goldstein et al. 1961; Wirts and Goldstein, 1963). The studies by Cregan and Hayward (1953) and Cregan, Dunlop and Hayward (1953) using the method of Blacklock and co- workers (1937) in which they sampled the small bowel contents directly at operation have helped considerably to clarify ideas on the subject. In spite of this, as French (1961) points out in a recent review of the literature, no clear picture has emerged concerning the bacteriological status of the small intestine.We have been interested for some time in the possible relation of bacteria to small intestinal disease (Girdwood, 1950; 1955a; 1955b; Doig and Girdwood, 1960), and this paper reports the findings of the bacterial flora in four different groups of patients who were studied by an intubation technique.As part of the investigation an attempt was made to study the uptake of labelled cyanocobalamin in vitro by the coliform type organisms isolated from the small intestine, note also being taken of the rate of uptake under these conditions

Blocking Java Applets at the Firewall

This paper explores the problem of protecting a site on the Internet against hostile external Java applets while allowing trusted internal applets to run. With careful implementation, a site can be made resistant to current Java security weaknesses as well as those yet to be discovered. In addition, we describe a new attack on certain sophisticated firewalls that is most effectively realized as a Java applet

Nothing Recedes Like Success - Risk Analysis and the Organizational Amplification of Risks

Professor Freudenburg believes that there is room for improvement in Risk analysis, particularly in drawing on systematic studies of human behavior in the calculation of real, empirical probabilities of failure. The need is argued to be especially acute where technological Risks are associated with low expected probabilities of failure and are managed by human organizations for extended periods of time. This permits complacency to set in

Joseph Conrad and Britain's Dream of Empire

This article explores the first chapter of Joseph Conrad's Lord Jim focusing on the possible meanings of the word "Patna". I argue that Conrad intended the term to suggest that the ship and its fate was a metaphor for the British Empire. "Patna" was a reference to opium upon which the empire was built. The book was intended as a critique of empire and as an antidote to the popular literature of the day which glorified the empire as a field for adventure in the "Boy's Own" writing of the late Victorian era

The Path to Gun Control in America Goes through Political Philosophy

This essay argues that gun control in America is a philosophical as well as a policy debate. This explains the depth of acrimony it causes. It also explains why the technocratic public health argument favored by the gun control movement has been so unsuccessful in persuading opponents and motivating supporters. My analysis also yields some positive advice for advocates of gun control: take the political philosophy of the gun rights movement seriously and take up the challenge of showing that a society without guns is a better society, not merely a safer one

Struggling With ‘Security’: National Security and Labour in the Ports

Systems of social protection are being quickly and quietly recast by developments in a surprising policy area. The rapidly expanding infrastructure of national security policy in Canada compromises labour rights and social forms of security. Security clearance programs, under development for port workers, compromise employment security by making workers and their families subject to invasive screenings that violate privacy, allow for job suspension based on 'reasonable suspicion' of terrorist affiliation, and offer no meaningful independent appeals process. New security regulations threaten to institutionalize racial profiling and undermine collective bargaining. Moreover, there are plans to generalize these programs across the transport sector - a large part of the labour force that includes trucking, mass transit, airport, and rail workers. In this paper I look at ongoing struggles over port security in Canada. I suggest that national security policy as backdoor labour policy works to institutionalize 'anti-social' forms of security
