Abstract

This is a companion article to “Grease Pumpability” by Dr. Wyllie that appeared in our January/February issue. That article discussed the factors governing the flow properties of grease and stated how this data could be used to assess the suitability of systems for dispensing greases. The present article deals with work done on oil separation from greases subjected to pressure, especially in spring‐loaded grease cups and describes a special test unit for this work. The results show the effect of pressure and temperature and the greater resistance to oil separation of greases containing high viscosity oil.

Abstract

The factors governing the flow properties of grease are discussed with particular reference to the RN multipurpose grease XG‐274 and the soft lime‐base grease LG‐380. Results obtained at 70°F using a pumping rig with pipes of ½ inch, ¾ inch or ¼ inch external diameter are presented in terms of apparent viscosity in line with the procedure approved by the National Lubricating Grease Institute. The data can be used to assess the suitability of systems proposed for dispensing the greases, supplemented where necessary by apparent viscosity measurement by Standard Method ASTM‐D 1092.

Abstract

THE Admiralty Oil Laboratory recently held an Open Day to celebrate their coming of age. Established initially at Brentford in 1953 (as a result of the “Recommendation of the Admiralty Oil Quality Committee” under Lord Geddes in 1951), the laboratory moved to its present site at Fairmile, Cobham, in 1968.

Abstract

Purpose

This study aims to examine the potential of two artificial intelligence (AI)-based algorithms, namely, adaptive neuro-fuzzy inference system (ANFIS) and gene expression programming (GEP), for indirect estimation of the ultimate bearing capacity (qult) of rock foundations, which is a considerable civil and geotechnical engineering problem.

Design/methodology/approach

The input-processing-output procedures taking place in ANFIS and GEP are represented for developing predictive models. The great importance of simultaneously considering both qualitative and quantitative parameters for indirect estimation of qult is taken into account and explained. This issue can be considered as a remarkable merit of using AI-based approaches. Furthermore, the evaluation procedure of various models from both engineering and accuracy viewpoints is also demonstrated in this study.

Findings

A new and explicit formula generated by GEP is proposed for the estimation of the qult of rock foundations, which can be used for further engineering aims. It is also presented that although the ANFIS approach can predict the output with a high degree of accuracy, the obtained model might be a black-box. The results of model performance analyses confirm that ANFIS and GEP can be used as alternative and useful approaches over previous methods for modeling and prediction problems.

Originality/value

The superiorities and weaknesses of GEP and ANFIS techniques for the numerical analysis of engineering problems are expressed and the performance of their obtained models is compared to those provided by other approaches in the literature. The findings of this research provide the researchers with a better insight to using AI techniques for resolving complicated problems.

Abstract

THE importance of the book as an educational agency has so long been recognized, that it will be unnecessary for me to dwell upon that side of the question. Yet it is impossible to ignore it altogether, for it is in the educational power of the book that we find the main reason for the existence of the school library. The elementary schools carry education up to a certain point, and the technical schools and universities take it up and carry it still further, but it is the library—or at any rate the book—which co‐ordinates the whole ; many people, indeed, have no education beyond the elementary school, except what they obtain from books. From this, the part played by the school library becomes obvious. Not only is it a powerful educator in itself, but it prepares the individual for the use of the Public Library and of books in general in the period following school life. Also, I need hardly point out that, although the use of the text‐book is dis pensed with as far as possible, the whole modern system of teaching is founded on the use of books.

Abstract

THE above two‐day symposium sponsored by the Tribology Group of the Institution of Mechanical Engineers and held at their h.q. in London from the 19th‐20th February, clearly demonstrated that grease is an engineering component and needs as much attention in selection and application as might be given to the design of the component that it lubricates.

Abstract

Botany continues to be a popular publishing area for reference books that range from manuals on experimental biochemical methods to guides for studying and identifying the flora of regions, counties, and parks. In an attempt to reduce the voluminous amount of literature to manageable size this survey will focus on botanical reference works published during 1977–78 that are suitable for academic libraries. Applied areas such as agriculture, horticulture, and forestry are not included; the numerous regional guides or keys to flora are not noted here unless they have more than provincial importance.

Abstract

Purpose

Testing technologies for policing is costly and laborious. Previous research found that police can be reticent about technology adoption. The purpose of this paper is to examine law enforcement adoption of programmatic innovations focused on particular crime types (radiological and nuclear threats).

Design/methodology/approach

First, an expert police panel explored readiness to adopt an advanced technology (personal radiation detectors (PRDs)). A survey was then developed from the panel findings (n=101 sampled from East Coast metropolitan police).

Findings

Results indicated that on-duty device adoption was likely, but not off-duty. In addition, concerns about ease of carrying PRDs, personal health and security issues, and concerns about job performance were raised. Furthermore, findings suggest that police respond negatively to financial incentives, and focus instead on how innovations can contribute to their own safety and that of their immediate families. Additionally, results indicate that false positives are not a significant barrier to adoption, but device training is important.

Practical implications

This work gives insight how to engage officers more meaningfully in technology adoption for benefit of policing in the field.

Originality/value

This work expands previous police adoption literature and advances understanding of the increasing role officers are taking in counter-terrorism efforts in the USA with applications around the world.

Abstract

Purpose

The purpose of this study is to investigate the knowledge management capabilities (KMCAP) in enterprise systems value-adding processes (ENTVA) through the big data capabilities (BDCAP) spectrum.

Design/methodology/approach

The proposed framework model is quantitatively tested using the Smart PLS method. An online questionnaire is developed and distributed to 120 technicians and knowledge workers in the royal commission for Yanbu industry (RCYI).

Findings

The findings of this study conclude that KMCAP has a significant direct effect on ENTVA and BDCAP. Also, this study concludes with interesting findings on the KMCAP domains.

Research limitations/implications

The study findings propose a wide-ranging awareness of knowledge management processes and BDCAP in the industrial enterprise systems environment. Future studies should consider other variables and different sectors and contexts.

Practical implications

This study includes implications for the full mediation effect of BDCAP between KMCAP and ENTVA.

Originality/value

This study demonstrates the relationship between three vital processes of KMCAP “knowledge management acquisition, knowledge management sharing and knowledge management emission” and ENTVA mediates by BDCAP in the context of the RCYI in Saudi Arabia.

Abstract

Purpose

The purpose of this paper is to examine financial management in the Pre‐Reformation church in Aberdeen, Scotland during the bishopric of Bishop William Elphinstone (1488‐1514).

Design/methodology/approach

The paper employs a combination of literature‐based analysis, archival research and the use of biographies in order to examine aspects of financial management within the Pre‐Reformation church in Aberdeen, Scotland.

Findings

There is evidence that accounting for assets and income was mobilised in order to achieve social aims. Recording mechanisms give visibility to the church's remuneration and governance strategy. Together, these examples show that there was no evidence of a sacred/secular divide in this context.

Research limitations/implications

Archives may be incomplete but can give insight into financial management in historical context and aspects of the sacred/secular divide.

Originality/value

This paper aids understanding of visibility and governance possibilities afforded by accounting that has been mobilised in an historic setting in order to achieve social aims.
