The purpose of this paper is to investigate effects of layer thickness on densification, surface morphology, microstructure and mechanical and corrosion properties of 420 stainless steel fabricated by laser-powder bed fusion (L-PBF).

Standard specimens were printed at layer thickness of 10, 20 and 30 µm to characterize Archimedes density, surface roughness, tensile strength, elongation, hardness, microstructural phases and corrosion performance in the as-printed and heat-treated condition.

Archimedes density slightly increased from 7.67 ± 0.02 to 7.70 ± 0.02g/cm³ and notably decreased to 7.35 ± 0.05 g/cm³ as the layer thickness was changed from 20 µm to 10 and 30 µm, respectively. The sensitivity to layer thickness variation was also evident in properties, the ultimate tensile strength of as-printed parts increased from 1050 ± 25 MPa to 1130 ± 35 MPa and decreased to 760 ± 35 MPa, elongation increased from 2.5 ± 0.2% to 2.8 ± 0.3% and decreased to 1.5 ± 0.2, and hardness increased from 55 ± 1 HRC to 57 ± 1 HRC and decreased to 51 ± 1 HRC, respectively. Following heat treatment, the ultimate tensile strength and elongation improved but the general trends of effects of layer thickness remained the same.

Properties obtained by L-PBF are superior to reported properties of 420 stainless steel fabricated by metal injection molding and comparable to wrought properties.

This study successfully the sensitivity of mechanical and corrosion properties of the as-printed and heat-treated parts to not only physical density but also microstructure (martensite content and tempering), as a result of changing the layer thickness. This manuscript also demonstrates porosity evolution as a combination of reduced energy flux and lower packing density for parts processed at an increasing layer thickness.

The paper seeks to describe the setting up of the Energy and Resources Institute (TERI) Digital library, which provides better single window access for researchers to access the structured information from their desktop. The aim of this paper is to share the experience gained and invite comments and suggestions for further improvement.

The paper describes a case study of TERI's Integrated Digital Library resources and digitization in detail and how the digital resources can be accessed through a single window. It also deals with basic problems and suggests practical solutions.

The paper finds that TERI Integrated Digital Library has been created to provide access to all digital and digitized offline and online resources, online e‐journals, electronic documents and virtual resources, and virtual libraries. The purpose of the integrated library is to provide a single window to researchers, through which they can access all the resources (both digitally born resources and digitized documents). Once users are able to access the Digital Library homepage, all the electronic resources are accessible using linkages with a single click, no matter whether they are available in a database or as a simple file in a virtual collection. A physical digital library has been created to address access to all the LAN connected systems that provide CD‐ROM access and journals and books downloaded or purchased for all time free access to in‐house users.

Integration has helped in saving researchers' valuable time. Library management has become easier and much more effective than was previously the case. Any additions to existing resources are announced by e‐mail for user access. Future plans are to make the resources highly interoperable across platforms or applications, so that platforms should not be a problem. Once a search is initiated, the search engine from the main search window should be able to hand over the search to subsequent search windows for any given database (bibliographic and full text). Once a search is handed over to the subordinate search engines, it should be able to retrieve the items and display the retrieved items in the main window. Future libraries seem to have no escape from the integrated digital library approach other than to an integrated digital collection that will make all available resources accessible from a single window.

This paper could be useful for small and medium special and research libraries who do not have enough funds to start with commercially available digital library software. This paper shows the way to start using Open Source Software, which is easy to use and has been used by the libraries with little effort.

The paper describes the setting up of The Energy and Resources Institute (TERI) electronic library in New Delhi, India to provide better services for the researchers to access the structured information from the desk top. The aim of this paper is to share the experience gain and invite comments and suggestion for further improvement.

The paper describes a case study of TERI and how the electronic library has developed.

TERI Electronic Library (EL) was created to provide access to online resources, online e‐journals, electronic documents and virtual resources. The virtual libraries i.e. internet sources, together, have now crystallized to more or less to a full‐fledged EL that can be browsed as well as searched. In TERI, electronic services like Current Awareness and Alerts services apart from establishing a Virtual Information Centre has further supplemented the EL. A physical electronic library has been created to address the access to all the local area network (LAN) connected systems that provide CD‐ROM access and journals and books available for download for all time free access to in‐house users.

The usage has become handier for the researchers and has helped in saving their valuable time. Library management has also become easier. Any addition to the existing resources is announced by e‐mail for user access. The future plan is to make the whole resources dynamic in nature. The future of libraries seems to have no escape from that of becoming the EL.

This paper could be useful for the small and medium special and research libraries who do not have enough funds to start an electronic library in these lines.

The probability distribution of major length and aspect ratio (major length/minor length) of wear debris collected from gear oil used in planetary gear drive were analysed and modelled. The paper aims to find an appropriate probability distribution model to forecast the kind of wear particles at different running hour of the machine.

Used gear oil of the planetary gear box of a slab caster was drained out and charged with a fresh oil of grade (EP-460). Six chronological oil samples were collected at different time interval between 480 and 1,992 h of machine running. The oil samples were filtered to separate wear particles, and microscopic study of wear debris was carried out at 100X magnification. Statistical modelling of wear debris distribution was done using Weibull and exponential probability distribution model. A comparison was studied among actual, Weibull and exponential probability distribution of major length and aspect ratio of wear particles.

Distribution of major length of wear particle was found to be closer to the exponential probability density function, whereas Weibull probability density function fitted better to distribution of aspect ratio of wear particle.

The potential of the developed model can be used to analyse the distribution of major length and aspect ratio of wear debris present in planetary gear box of slab caster machine.

This paper describes the personal history and intellectual development of Morris B. Holbrook (MBH), a participant in the field of marketing academics in general and consumer research in particular.

The paper pursues an approach characterized by historical autoethnographic subjective personal introspection or HASPI.

The paper reports the personal history of MBH and – via HASPI – interprets various aspects of key participants and major themes that emerged over the course of his career.

The main implication is that every scholar in the field of marketing pursues a different light, follows a unique path, plays by idiosyncratic rules, and deserves individual attention, consideration, and respect … like a cat that carries its own leash.

In the case of MBH, like (say) a jazz musician, whatever value he might have depends on his originality.
