Abstract

The glasshouse industry of Britain occupies a mere 0.05% of the total area of land under crops other than grass. On this basis it would seem disproportionate to devote the activities of a national research institute to this small area. The Glasshouse Crops Research Institute is, however, serving an economically extremely important sector of horticulture. The total annual value of crops grown under glass is approximately £60 million and the Institute also serves the needs of the mushroom industry valued at £16 million.

Abstract

Purpose

This paper aims to evaluate the theoretical performance of elliptical dam bearing (EDB). The objective of this paper is to study the influence of eccentricity ratio, dam parameters and micropolarity parameters on the stability of EDB with respect to micropolar lubrication.

Design/methodology/approach

In this study, the modified Reynolds’ equation for dynamic state is solved using the finite element method and Galerkin technique. A MATLAB code is written to compute pressure and stability and also to analyse the characteristics. The stability parameters of an EDB are computed for selected values of eccentricity ratios at four levels in the range of 0.20 to 0.35 and for length-diameter ratio of 2.0.

Findings

The results from stability analysis reveal that micropolar lubricated EDB provides better stability at smaller material length due to increased effective viscosity. Hence, it is better to select the smaller characteristic length and higher dam width to achieve optimum performance of these bearings.

Originality/value

Very few researchers investigated the effects of working eccentricity, bearing dam and micropolar fluid parameters on the EDB in the past. It is important to study these aspects for optimum performance of bearings.

Abstract

Purpose

This paper aims to focus on the accurate analysis of the fractional heat transfer in a two-dimensional (2D) rectangular monolayer tissue with three different kinds of lateral boundary conditions and the quantitative evaluation of the degree of thermal damage and burn depth.

Design/methodology/approach

A symplectic method is used to analytically solve the fractional heat transfer dual equation in the frequency domain (s-domain). Explicit expressions of the dual vector can be constructed by superposing the symplectic eigensolutions. The solution procedure is rigorously rational without any trial functions. And the accurate predictions of temperature and heat flux in the time domain (t-domain) are derived through numerical inverse Laplace transform.

Findings

Comparison study shows that the maximum relative error is less than 0.16%, which verifies the accuracy and effectiveness of the proposed method. The results indicate that the model and heat source parameters have a significant effect on temperature and thermal damage. The pulse duration (Δt) of the laser heat source can effectively control the time to reach the peak temperature and the peak slope of the thermal damage curve. The burn depth is closely correlated with exposure temperature and duration. And there exists the delayed effect of fractional order on burn depth.

Originality/value

A symplectic approach is presented for the thermal analysis of 2D fractional heat transfer. A unified time-fractional heat transfer model is proposed to describe the anomalous thermal behavior of biological tissue. New findings might provide guidance for temperature prediction and thermal damage assessment of biological tissues during hyperthermia.

Abstract

It has often been said that a great part of the strength of Aslib lies in the fact that it brings together those whose experience has been gained in many widely differing fields but who have a common interest in the means by which information may be collected and disseminated to the greatest advantage. Lists of its members have, therefore, a more than ordinary value since they present, in miniature, a cross‐section of institutions and individuals who share this special interest.

Abstract

Given the backdrop of a global influx of refugees and high numbers of youth under the age of 18 among counts of forcibly displaced persons, this chapter examines the literature on educational experiences among resettled refugees in Western countries. Young refugees typically face a complex set of unique challenges and adversities including disruptions in their schooling, displacement, exposure to potentially traumatic events, and resettlement stressors. Youth and parent interactions with schools are influenced by linguistic and cultural differences, which can make it difficult to communicate and advocate for young refugees' educational needs. The chapter provides a review of educational literature on resettled refugee youth. We use a socioecological framework and offer a protective and promotive lens, including psychosocial issues, to consider for school-based prevention and intervention programs. The chapter builds upon Pastoor (2015), who advocated a holistic approach with refugee students in school-based settings.

Abstract

THIS number will appear at the beginning of the Leeds Conference. Although there is no evidence that the attendance will surpass the record attendance registered at the Birmingham Conference, there is every reason to believe that the attendance at Leeds will be very large. The year is one of importance in the history of the city, for it has marked the 300th anniversary of its charter. We hope that some of the festival spirit will survive into the week of the Conference. As a contributor has suggested on another page, we hope that all librarians who attend will do so with the determination to make the Conference one of the friendliest possible character. It has occasionally been pointed out that as the Association grows older it is liable to become more stilted and formal; that institutions and people become standardized and less dynamic. This, if it were true, would be a great pity.

Abstract

In this chapter, the authors adopt a macrofoundations perspective to explore punishment within institutional theory. Institutional theorists have long focused on a single type of punishment – retribution – including the use of sanctions, fines, and incarceration to maintain conformity. The authors expand the types of punishment that work to uphold institutions, organized by visible and hidden, and formal and informal characteristics. The four types of punishment include (1) punishment-as-retribution; (2) punishment-as-charivari; (3) punishment-as-rehabilitation; and (4) punishment-as-vigilantism. The authors develop important connections between punishment-as-charivari, which relies on shaming efforts, and burgeoning interest in organizational stigma and social evaluations. The authors also point to informal types of punishment, including punishment-as-vigilantism, to expand the variety of actors that punish wrongdoing, including actors without the legal authority to do so. Finally, the authors detail a number of questions for each type of punishment as a means to generate a future research agenda.
