The purpose of this paper is to investigate the effects of liquid carbon dioxide (LCO₂) on grinding of stainless steel.

A factorial experimental approach was used to compare the LCO₂'s performance against grinding under dry air and emulsion coolants.

The experimental results have a great use to practitioners. It was found that under special conditions, LCO₂ proves to be an alternative coolant for grinding of temperature sensitive materials. Furthermore, grinding under LCO₂ conditions produced the lowest tangential force, while the normal forces were close to the values found under emulsion fluid environment. When compared to grinding under dry conditions, LCO₂ coolant was successful in reducing the work piece temperatures. LCO₂ and emulsion conditions inhibit work hardening by reducing material deformation at the grinding zone.

The paper shows that sub‐zero temperature coolants have the ability to bring about lower grinding temperatures than what is typically achieved under conventional fluids.

The librarian and researcher have to be able to uncover specific articles in their areas of interest. This Bibliography is designed to help. Volume IV, like Volume III, contains features to help the reader to retrieve relevant literature from MCB University Press' considerable output. Each entry within has been indexed according to author(s) and the Fifth Edition of the SCIMP/SCAMP Thesaurus. The latter thus provides a full subject index to facilitate rapid retrieval. Each article or book is assigned its own unique number and this is used in both the subject and author index. This Volume indexes 29 journals indicating the depth, coverage and expansion of MCB's portfolio.

In the matter of food purity and control Hospital Catering Services have been outside the law, a privileged position where the general law of food and drugs have never applied and the modern regulatory control in food hygiene has similarly not applied. In the eyes of the general public hospital catering standards have always been high above the general run of food preparation. As the NHS continued, complaints began gradually to seep out of the closed community, of dirt in the kitchens and prevalent hygiene malpractices. The general standard for most hospitals remained high but there were no means of dealing with the small minority of complaints which disgusted patients and non‐cater‐ing staff, such as insect and rodent infestations, and an increase in the frequency of food poisoning outbreaks.

Throughout history, from ballads to requiems, music has played an important social role in reflection on mortality. Not only do musicians articulate their angst and thoughts about death, but, in so doing, they enable listeners to explore their own feelings. While the relationship between music and mental health can be examined from a number of perspectives, two broad approaches can be taken: artist-centred approaches and listener-centred approaches. The first analyses the life and work of artists, focussing particularly on the ways in which they explore death and angst in their music. The second looks at the ways in which the life and work of an artist is interpreted by listeners. Within these general approaches, a complex set of questions emerge – often at the interface of both approaches. How is the music used by listeners in their reflection on mortality? How is music used to manage mental health? Does reflection on the life and work of an artist contribute to suicidal ideation? Is the reception of music altered by an artist’s suicide? Using both these approaches and drawing particularly on the work of Émile Durkheim, this discussion demonstrates the significance of popular music analysis for death studies, focussing particularly on the issues surrounding popular music’s relationship to suicidal ideation.
