Abstract
Purpose
This paper aims to compare the performance, emission and combustion characteristics of E20 biodiesel with diesel-water emulsion and eucalyptus water emulsion.
Design/methodology/approach
This research expounds the trans-esterification process apparently. Various biodiesel blends were made to go through the trans-esterification process to make it suitable for feeding them into the low heat rejection (LHR) engine. E20 biodiesel – 20% of eucalyptus oil by volume with diesel was chosen to carry out the research as it was found to be the best blend with diesel. The volume of water content in diesel water emulsions was varied by 5, 10 and 15% in DWM1 (Diesel Water Mixture1), DWM2 (Diesel Water Mixture2) and DWM3 (Diesel Water Mixture3), respectively. Similarly, the volume of water content in eucalyptus water emulsions was varied with emulsification ratio of E20 biodiesel. Partially stabilized zirconia was coated over top surface of the piston and valve facing of the LHR engine.
Findings
From the researches carried out, DWM3 (Diesel Water Mixture3) was found to be superior when compared with other diesel-water emulsions in LHR engine. The overall efficiency was found to be higher for EWM3 than other biofuels tested the in LHR engine.
Originality/value
This investigational experiment can be further extended to multi-cylinder engine and to improve the cetane number, Di ethyl ester (DEE) fuel additives can be added.

Abstract
Purpose
To improve the wear resistance of the sliding boot, the wear-resistant Fe-21 Wt.% Cr-5 Wt.% B alloy is prepared, and the wear mechanism is studied under dry sliding condition.
Design/methodology/approach
The anti-wear Fe-21 Wt.% Cr-5 Wt.% B alloy is prepared by powder metallurgy technique. The tribological behavior of Fe-Cr-B alloy sliding against ASTM 1045 steel pin is studied at 30-60 N and 0.03-0.12 m/s using a reciprocating pin-on-disk tribometer under dry sliding condition. Meanwhile, the ASTM 5140 and 3316 steel are studied as compared samples.
Findings
The friction coefficients of tested specimens increase with the increasing normal load. However, this effect is the opposite in case of different sliding speeds. The specific wear rates increase as the sliding speed and normal load increase. The Fe-Cr-B alloy shows the best tribological properties under the dry sliding condition and the wear mechanism is mainly ploughing.
Originality/value
This wear-resistant Fe-21 Wt.% Cr-5 Wt.% B alloy can replace the traditional materials to process the sliding shoes and improve the service life of coal mining machine.

Abstract
Purpose
This study aims to determine the level of knowledge in searching, evaluating, information management competency and to find differences among research scholars’ in terms of their information literacy (IL) competency with regards to gender and academic designation.
Design/methodology/approach
A survey method was conducted to collect the data from the research scholars’ pursuing their doctoral degrees in Manonmaniam Sundaranar University, Tamil Nadu, India.
Findings
The results of this study revealed that the majority have used simple search and were not using the Online Public Access Catalogue. They were not able to assess the information retrieved and the assistance from the library staff to locate the resources was found to be minimal. This study also highlighted some of the problems faced by the research scholars and provided some suggestions based on the findings. This study highlights the need to adopt a new IL framework and conduct user literacy training programmes for effective use of the resources.
Practical implications
This study also has practical implications in terms of assessing the IL competency among the research scholars and significant variations which identified through demographics and assessment of IL competency will enable policymakers to develop a framework for brand new literacy instructions. The results may help to frame long-term strategies to motivate and train the research scholars in the effective use of technologies for improving their academic performance.
Originality/value
This study used a questionnaire as tool to collect the data. The outcome of the results will help the librarians and authorities to discuss research scholars’ IL competency and take appropriate decisions to improve their IL skills.

Abstract
Purpose
This study aims to explore various skills of library professionals working in management institutions of Kerala State, India.
Design/methodology/approach
A survey method was used by distributing online questionnaire as a data collection tool. The questionnaires were distributed to the library professionals working in management institutions in Kerala State, India.
Findings
The study’s results revealed that the library professionals were competent with managerial, communication and interpersonal skills. Conversely, they were lacking skills in statements such as institutional repository, web 2.0 and social networks. Their familiarity level with reference management tools, research and academic ethics, electronic publishing and management of open-access resources, were also not satisfactory. They need knowledge of other ICT skills such as designing and maintaining in-house databases, video conferencing tools, advanced troubleshooting creating and managing metadata, handling RFID technology and knowledge in solving issues while organizing webinars. Based on the findings, the study has suggested some recommendations which will enable the government/institutions to take appropriate measures to improve their skills.
Practical implications
This study will enable the policymakers to identify in which area the library professionals are weak and develop a strategy and framework for increasing the level of their skills.
Originality/value
This study provides the views of the library professionals working in management institutions in India and warrants the library professionals to enhance their skills, especially on research ethics and publications and ICT skills.

Abstract
Purpose
This study aims at improving combustion process to reduce emissions. Emissions such as carbon monoxide, particulate matter and unburnt hydrocarbons are a result of incomplete combustion. These emissions have useful energy but cannot be reclaimed. Hence, to enhance combustion, effect of biofuel blending on diesel combustion was investigated.
Design/methodology/approach
Essential oils have been found easier for blending with diesel because of simple molecular structure compared to vegetable oils. Lavender oil is an essential oil which has not yet been studied by blending with diesel. The major constituents of lavender oil are linalyl acetate (cetane number improver) and linalool (nitrogen oxides reduction). A single-cylinder, four-stroke diesel engine was run by blending diesel with lavender oil (Lavandula angustifolia oil [LAO]) in varying proportions, 5%, 10% and 15% by volume.
Findings
Higher heat release rate (HRR) was observed using lavender oil blends compared to pure diesel. Compared to diesel, an increase in brake-specific fuel consumption using blends was observed. LAO15 has the lowest CO emissions at all loading conditions, 29.3% less at 100% load compared to diesel. LAO5 and LAO15 have 6.9% less HC emissions at 100% load condition compared to diesel. LAO15 has only 1.3% higher NOx emissions compared to diesel at 100% load condition. LAO5 has the lowest smoke content at all loading conditions.
Research limitations/implications
Lavender oil was used directly without any processing. Tested on single-cylinder engine.
Originality/value
To the best of the author’s knowledge, currently, there is no published work on lavender oil–diesel combination. Lavender oil can provide a simple renewable solution for diesel additives with potential up to 15% blending.
