Abstract

Purpose

The purpose of this paper is to present a deterministic, stochastic and reliability analysis through numerical simulations in 2D and 3D dynamic fluid‐structure interaction problems.

Design/methodology/approach

The perturbation methods allied to reliability analysis are applied to fluid‐structure finite element models. Reliability analysis couples finite element analysis with first and second order reliability methods and ant colony optimization in a modified first order reliability method.

Findings

Results obtained show the potentialities of the proposed methodology and encourage improvement of this procedure for use in complex coupled fluid‐structure systems.

Originality/value

The understanding of the mechanical interaction between a fluid and an elastic solid has a capital importance in several industrial applications. In order to couple the behaviour of two different media, deterministic models have been proposed. However, stochastic analysis has been developed to deal with the statistical nature of fluid‐structure interaction parameters. Moreover, probabilistic‐based reliability analysis intends to find safe and cost‐effective projects.

Abstract

The information which has hitherto appeared in the daily press as to the evidence laid before the Departmental Committee which is inquiring into the use of preservatives and colouring matters can hardly have afforded pleasant reading to the apologists for the drugging of foods. It is plainly the intention of the Committee to make a thorough investigation of the whole subject, and the main conclusions which, in the result, must bo forced upon unbiassed persons by an investigation of this character will be tolerably obvious to those who have given serious attention to the subject. At a later stage of the inquiry we shall publish a full account of the evidence submitted and of the Committee's proceedings. At present we may observe that the facts which have been brought forward fully confirm the statements made from time to time upon these matters in the BRITISH FOOD JOURNAL, and amply justify the attitude which we have adopted on the whole question. Representatives of various trade interests have given evidence which has served to show the extent to which the practices now being inquired into are followed. Strong medical evidence, as to the dangers which must attach to the promiscuous and unacknowledged drugging of the public by more or less ignorant persons, has been given; and some medical evidence of that apologetic order to which the public have of late become accustomed, and which we, at any rate, regard as particularly feeble, has also been put forward. Much more will no doubt be said, but those who have borne the heat and burden of the day in forcing these matters upon the attention of the Legislature and of the public can view with satisfaction the result already attained. Full and free investigation must produce its educational effect ; and whatever legal machinery may be devised to put some kind of check upon these most dangerous forms of adulteration, the demand of the public will be for undrugged food, and for a guarantee of sufficient authority to ensure that the demand is met.

Abstract

The contiguous Americas offer a conceptual image of a unified and major economic marketplace. A campaign to solidify this image should be developed and implemented to improve political relations and the balance of power between and among the nations involved. Not campaigning for a united marketplace of the Americas risks fractionalization of economic power in smaller markets. The cultures are no more diverse than those in the other two global market areas—Asia and Europe—and the languages less so. Additionally, certain confederations and associations already exist to help structurally unify the Americas as a single marketplace.

Abstract

Purpose

Circular economy (CE) is a structured model of production and consumption involving sharing, leasing, reusing, recycling, repairing and refurbishing existing products or materials sustainably. Despite the numerous benefits of CE adoption, the construction and demolition (C&D) sector still struggles to comprehensively understand, integrate and adopt this approach. This study provides a comprehensive analysis of CE within the C&D sector and proposes a structured conceptual framework for an effective construction and demolition waste management (CDWM) program.

Design/methodology/approach

A systematic literature review (SLR) was conducted using the “Preferred Reporting Items for Systematic Reviews and Meta-Analyses” (PRISMA) framework to search for articles across three databases: Scopus, Web of Science and EBSCO. EndNote software and Excel spreadsheets were used to analyze and synthesize the articles up to 2024. A total of 102 articles were included in the study. Various key facets of the CE in CDWM, including barriers and mitigation actions, enablers, tools and techniques, benefits, strategies and frameworks, have been thoroughly reviewed and analyzed for the C&D sector to understand their nature and effectively adopt the CE approach in CDWM operations.

Findings

The findings provide a comprehensive analysis of different facets of CE in CDWM and a structured conceptual framework for the effective adoption of CE. This will contribute to improving the management of CDWM in the C&D sector. The outcomes offer a comprehensive knowledge base of CE in CDWM to managers, planners, decision-makers, stakeholders and researchers, enabling effective deployment.

Practical implications

This study offers a substantial knowledge base to researchers by examining various key facets of CE in CDWM, aiding further exploration of research in the same domain. Additionally, it assists C&D managers, planners, stakeholders and decision-makers by furnishing a structured conceptual framework of CE, thereby enhancing effective implementation. Furthermore, this study supports society by providing a pathway to improve C&D waste circularity through the execution of CE.

Originality/value

This study is the first to comprehensively review the various facets of CE from a CDWM perspective and to propose a structured conceptual framework for the effective adoption of CE in the C&D sector. Additionally, it not only advances theoretical knowledge of CE adoption in the CDWM field but also provides practical guidance to stakeholders on how to implement a comprehensive CE approach to enhance C&D waste circularity.
