Abstract

As a way of enhancing the mechanical properties of photopolymer‐based parts produced by layered manufacturing (LM) techniques, the use of short glass‐fibre reinforcements has been recently explored in the literature. This paper proposes a novel methodology that utilizes a modified rule‐of‐mixtures model for the prediction of the mechanical properties of such layered composites. The prediction process employs empirical data on (i) the fibre‐matrix interface, (ii) the fibres’ geometrical arrangement within the specimens (i.e. fibre‐orientation distribution), and (iii) the fibre‐length distribution. The effects of the fibre‐orientation and fibre‐length distributions are accounted for in the prediction model by the fibre‐length‐correction and orientation‐efficiency factors. Comparison of extensive experimental results and model‐based predictions of mechanical properties of layered composites demonstrated the effectiveness of the proposed estimation methodology.

Abstract

Analytical/Computational models for the fused deposition (FD) material stiffness and strength as a function of mesostructural parameters are developed. Effective elastic moduli are obtained using the strength of materials approach and an elasticity approach based on the asymptotic theory of homogenization. Theoretical predictions for unidirectional FD‐acrylonitrile butadiene styrene materials are validated with experimentally determined values of moduli and strength. For moduli predictions, the results were found to be satisfactory with difference between experimental and theoretical values of less than 10 percent in most cases.

Abstract

Purpose

The purpose of this publication is to present a didactic concept with the targeted impact of a positive future vision. This paper reflects the effect of local educational action on the development of regionally optimised visions in rural regions of a European industrial state, compared with a rural region in the developing country of Senegal.

Design/methodology/approach

An assessment and analysis of two conceptual approaches to education and technology is conducted with a view to participating in a future multicultural participatory design process, and identifying the chances that communities have to build future‐oriented structures that support local roots and development.

Findings

In the short‐term, the technological and material results are the targeted localisation of a windmill in the (physical and cultural) countryside. In the long‐term, educative and social results are expected to strengthen local civil society, which is initiated by empowering students through their self‐responsibility in the Alpine region of Greifenburg, Austria. The “windmill” in the region is a publicly visible sign and a technology‐based icon in the landscape, based on local consensus on several levels and inspiring further regional consensus on energy, climate protection and its active creation through entrepreneurship in civil society.

Originality/value

Technology serves as a catalyst to trigger social cohesion among multiple cultures in a region and to enhance conviviality.

Abstract

Purpose

The aim of this study is to describe an improved experimental substrate for the mechanical testing of patient-specific implants fabricated using direct metal additive manufacturing processes. This method reduces variability and sample size requirements and addresses the importance of geometry at the bone/implant interface.

Design/methodology/approach

Short-fiber glass/resin materials for cortical bone and polyurethane foam materials for cancellous bone were evaluated using standard tensile coupons. A method for fabricating bone analogs with patient-specific geometries using rapid tooling is presented. Bone analogs of a canine radius were fabricated and compared to cadaveric specimens in several biomechanical tests as validation.

Findings

The analog materials exhibit a tensile modulus that falls within the range of expected values for cortical and cancellous bone. The tensile properties of the cortical bone analog vary with fiber loading. The canine radius models exhibited similar mechanical properties to the cadaveric specimens with a reduced variability.

Research limitations/implications

Additional replications involving different bone geometries, types of bone and/or implants are required for a full validation. Further, the materials used here are only intended to mimic the mechanical properties of bone on a macro scale within a relatively narrow range. These analog models have not been shown to address the complex microscopic or viscoelastic behavior of bone in the present study.

Originality/value

Scientific data on the formulation and fabrication of bone analogs are absent from the literature. The literature also lacks an experimental platform that matches patient-specific implant/bone geometries at the bone implant interface.

Abstract

Purpose

This article aims to explain why geography is a prime discipline for analysing globalisation and a multicultural view of Global Studies. The generic approach of human geography to first select an appropriate methodology is taken as a key approach.

Design/methodology/approach

Concepts from aggregate disciplines such as history, economics, and geography are scanned through during a short description of the historical genesis of these sciences and the paradigmatic shifts they have encountered.

Findings

There are four main theses: (1) values are created by appreciation; (2) development is growing jointly with responsibility; (3) accumulation of material value is seen as expenditure to achieve non‐material values; and (4) spatial relations are interrelated with social relations.

Research limitations/implications

Conceptual considerations have to be further corroborated by quantitative analyses using suitable metrics of “development”.

Practical implications

“Social and cultural geography” should contribute to any curriculum of “Global Studies”.

Social implications

Dialogue and discourse between world views is the essential, ideology‐free approach for understanding globalisation.

Originality/value

Unlike other scientific articles focusing on “facts”, this article focuses on perspectives. Thus, it explains “multi‐perspectivity” and a multi‐paradigmatic approach.

Abstract

Purpose

This research aims to design a green pharmaceutical supply chain (PSC) that reduces preventable pharmaceutical waste and effectively disposes of inevitable pharmaceutical waste. The main output of this study is the formulation of an integrated green PSC model involving all critical stakeholders, leading to improved environmental, economic and safety performance in medication management and delivery.

Design/methodology/approach

The research is based on literature and on secondary resources.

Findings

To green the PSC, every producer of waste is duty bound to facilitate the safe handling and disposal of waste. A cross boundary green PSC (XGPSC) approach is proposed to identify participants' contribution to the PSC. Peripheral influences are also recognised from professional and regulatory bodies.

Research limitations/implications

This study focuses solely on community PSC in the UK where patients receive medication from local community pharmacies and thus may be limited. The proposed XGPSC approach also needs to be tested and validated in practice. It may also be difficult to transfer some of the environmental practices proposed in this research into practice.

Practical implications

The environmental practices and actions proposed provide invaluable insight into various PSC activities, including purchasing, product design, prescription patterns and processes, medication use review, and customer relationship management.

Social implications

The proposed environmental actions encourage firm commitment from everyone to reduce, recycle or effectively dispose of pharmaceutical waste, with patients becoming stewards of medication rather than only consumers.

Originality/value

A cross boundary approach is developed to green the PSC, which encourages total involvement and collaboration from all participants in PSC.

Abstract

A study of 266 little‐known technical house journals in the US, UK and France is described. Methods of journal selection, location, and bibliographic control are discussed. A sample of technical articles from the journals was searched in abstracting and indexing services to determine their coverage and the extent to which such materials are prepublished or republished in standard periodicals. It was found that, although there are a significant number of technical articles published in house journals, the coverage of this literature in secondary sources is very low, and the literature is rarely included in standard periodicals.

Abstract

This paper defines market research reports, house journals and trade literature, discusses the availability of these forms of literature within the U.K. and finally considers their bibliographic control. The discussion on bibliographic control is not limited to literature emanating from the U.K. Since the three types of literature are very different from each other (although house journals and trade literature have features in common) they will be treated as quite separate cases. The need for, and use of these types of literature, undeniably very important topics, are nevertheless outside the scope of this paper.
