Abstract
The Conference on Anodised Aluminium, organised by the Aluminium Development Association and held in the new Cripps Hall at Nottingham University from September 12–14, was probably the first of its kind in the world and attracted nearly 300 delegates. Eighteen papers were discussed. In the following pages abstracts and conclusions from most of the papers are given, emphasis being placed on the corrosion aspects of the subject.

Abstract
Brightening solutions for aluminium. The chemical brightening of aluminium in mixtures based on phosphoric acid formed the subject of a series of experiments in which commercial purity aluminium panels were used in order to assess the influence of the aluminium content of the bath, and the effect of temperature upon the amount of metal removed. Four mixtures were employed: phosphoric‐sulphuric acid, phosphoric‐sulphuric‐nitric acid, phosphoric‐acetic‐nitric acid and phosphoric acid‐water‐nitric acid. If a highly specular finish is required, then the presence of about 5% (by volume) of nitric acid is essential. Acetic acid reduces the tendency for the rate of attack to increase with temperature, while water increases the maximum aluminium content which can be tolerated before the bath becomes unusable. Weight loss‐time curves are given for S1, S1B, S1C, NS4, HS10WP, HS15W and an Al (99.99%), 1.25% Mg, alloy treatment times up to 5 min. in the four solutions investigated. Except for HS15W, the response was found to be good for most materials, but a loss of brightness occurred with the lower‐purity materials on anodising.— (A. W. Brace and T. S. de Gromoboy, Trans.

Abstract
Non‐oxidising preservative. It is generally realised that oxidisation in a paint film is the first stage of decay. A product known as Camrex non‐oxidising preservative has been well tested over the years, and the manufacturers, Camrex Paints Ltd., claim that it never oxidises. Only one coat is required, resulting in a saving of labour, time and material, and reducing maintenance costs. The film remains flexible, contracting and expanding with the steel to which it adheres. It is said to be unaffected by most acids, alkalis, chemical fumes and moisture.

Abstract
APPLICATION of the so‐called high energy liquid fuels and high energy liquid oxidizers to power plants based on the jet propulsion principle is receiving the increasing interest and attention of rocket propellant chemists and power plant engineers universally. The aspect of substantially increased—as much as 50 per cent— energy per pound of propellant load or per cubic foot of propellant tankage over today's propellants has whetted scientific appetites and justified probing the field of high energy chemicals to determine, as logically and as practically as we can at the present time, the gains, problems, limitations and applications of these higher energy chemicals. The object of this paper is, in a general way, to discuss the subject of chemical rocket propellants in such a way that the following five questions will be, in part at least, answered or recalled to the minds of this audience for additional deliberation.

Abstract
FRANCE. Internal corrosion in pipes. Mild‐steel pipes as used in town gas distribution networks are corroded by the mixture of water vapour, carbon dioxide and oxygen. Corrosion occurs only if changes in temperature will cause condensation. The condensate forming on the metal is a heavily corroding agent. Once formed, the corrosion products will act as protective layers in certain circumstances.—(J. Morlet and G. Geoffray, paper read at the 74th Congress of the Association Technique de l'Industrie du Gaz en France, June 1957.)

Abstract
Quotations for the protection of substantial tonnages of widely different types of steelwork were obtained from eight companies, geographically distributed throughout England and Wales. All the companies had substantial facilities for blasting and for applying either paint or sprayed metal coatings.

Abstract
Purpose
This literature review examines women’s significant workplace challenges and explores mental toughness, a distinct non-cognitive ability associated with peak athletic performance. This study aims to understand this concept and its potential for women professionals facing similar challenges in an organisational context.
Design/methodology/approach
Based on a systematic literature review, this exploratory paper is an integrative literature review synthesising pre-existing knowledge using secondary scientific databases. This literature analysis will pave the way for comprehension of the existing body of research, identification of research gaps, and opportunities for further studies. Different typologies of mental toughness (MT) have been identified, and a new typology will emerge from this research study.
Findings
The study analyses over 100 articles based on MT typology and complex gender dynamics at work, especially the “broken rung” concept of trapping women in lower or mid-level roles in an organisation. This content analyses the recent emergence of the MT typology in academic research, with articles published after 2019 and a few earlier key works that shaped the concept of MT. In addition to contributing a comprehensive typology of MT and its impact on women professionals, this paper also provides recommendations for future research and individual-level development of MT to help women overcome workplace barriers globally.
Research limitations/implications
Understanding MT’s impact on women’s ability to overcome workplace barriers has HR implications, including hiring, retention, career advancement, training and closing gender gaps. This research may help individual women professionals adopt MT as a psychological resource to navigate work environment challenges. Further research is needed for practical insights, given this discussion is based on a literature review.
Practical implications
The practical implications of this study have a profound impact on human resource management practices within organisations, highlighting the multifaceted approach required to tackle gender disparity. A more inclusive and supportive work environment can be created by ensuring MT training is accessible to all employees. A comprehensive career development plan for women professionals, including but not limited to mentoring, executive sponsorship, skill-building training or stretched assignments, leadership coaching, networking opportunities, and increased visibility in the organisation are critical for career advancement and retention.
Originality/value
This study is a novel attempt to examine whether MT, which has proven effective in helping athletes achieve their goals, can be applied in a workplace environment. It is also a new endeavour to investigate whether women could use MT as a psychological tool to help them overcome obstacles in a diverse professional setting.

Abstract
Human performance, particularly that of the warfighter, has been the subject of a large amount of research during the past few decades. For example, in the Medline database of medical and psychological research, 1,061 papers had been published on the topic of “military performance” as of October 2003. Because warfighters are often pushed to physiological and mental extremes, a study of their performance provides a unique glimpse of the interplay of a wide variety of intrinsic and extrinsic factors on the functioning of the human brain and body. Unfortunately, it has proven very difficult to build performance models that can adequately incorporate the myriad of physiological, medical, social, and cognitive factors that influence behavior in extreme conditions. The chief purpose of this chapter is to provide a neurobiological (neurochemical) framework for building and integrating warfighter performance models in the physiological, medical, social, and cognitive areas. This framework should be relevant to all other professionals who routinely operate in extreme environments. The secondary purpose of this chapter is to recommend various performance metrics that can be linked to specific neurochemical states and can accordingly strengthen and extend the scope of the neurochemical model.
