Abstract

Purpose

This paper aims to investigate the tribological performance of the decanter cake feedstock biodiesel which was blended in 5 and 10 per cent volume with petroleum diesel.

Design/methodology/approach

The tribological performance of the decanter cake biodiesel was tested using the modified ASTM D4172 standard with temperature range from 300°C to 750°C and load range from 392 to 981 N while spindle speed is at 1,200 rpm.

Findings

At 5 per cent volume of biodiesel, friction reduced ranging from 10 to 45 per cent at all temperature and load ranges, whereas specific wear rate reduced ranging from 22 to 29 per cent at low load and 4 per cent to 15 per cent at high load for all temperature ranges. Addition up to 10 per cent volume of biodiesel reduced friction ranging from 10 to 35 per cent at all temperature and load ranges, whereas specific wear rate reduced ranging from 15 to 29 per cent only at low load for all temperature ranges.

Practical implications

The standardised test may not represent the actual condition of a real running diesel engine.

Originality/value

Because the lubricity of biodiesel was difficult to determine in a real running engine, this paper provided a standardised test for simplification.

Abstract

Purpose

The purpose of this paper is to review Lean Six Sigma (LSS) literature and report different definitions, demographics, methodologies and industries.

Design/methodology/approach

This paper highlights various definitions by different researchers and practitioners. A total of 235 research papers has been reviewed for the LSS theme, research methodology adopted, type of industry, author profile, country of research and year of publication.

Findings

From the review, four significant LSS classifications were identified that deal with the spread of LSS in different industries followed by observation for classification.

Practical implications

LSS is a strategy for success, but it did not examine its presence in various Industries. From this paper, readers can understand the quantum of its spread before implementing LSS. For academicians, it will be a comprehensive list of papers for research.

Originality/value

This paper reviews 235 research papers for their year, author profile, research methodology and type of industry. Various characteristics of LSS definitions and their theme are also reviewed.

Abstract

Purpose

This paper aims to analyse how both Lin’s birthplace identity and his Christian identity contributed to his fruitful public career and to ascertain which identity became the most significant.

Design/methodology/approach

Archival research is the main method used in this paper. The most important archives drawn from are the Daniel Tse Collection in the Special Collection and Archives of the Hong Kong Baptist University Library. Oral history has also been used in this paper to uncover more material that has not yet been discussed in existing scholarly works.

Findings

This paper argues that although Lin’s birthplace identity and social networks helped him to start his business career in Nam Pak Hong and develop into a leader in the local Chaozhou communities, these factors were insufficient to his becoming a respectable member of the Chinese elite in post-war Hong Kong. He became well known not because of his leading position in local Chaozhou communities or any great achievement he had obtained in business but because of his contribution to the development of Christian education. These achievements earned him a reputation as a “Christian educator”. Thus Lin’s Christian identity became more important than his birthplace identity in contributing to his successful public career.

Originality/value

This paper has value in showing how Christian influences interacted with various cultural factors in early Hong Kong. It also offers insights into Lin’s life and motivations as well as the history of the institutions he contributed to/founded. It not only furthers our understanding of the Chinese Christian business elite in early Hong Kong but also provides us with insights when further studying this group of people in other British colonies in Asia.
