- PurposeThe question of resource scarcity and emerging pressure of environmental legislations has brought a new challenge for the manufacturing industry. On the one hand, there is a huge population that demands a large quantity of commodities; on the other hand, these demands have to be met by minimum resources and pollution. Resource conservative manufacturing (ResCoM) is a proposed holistic concept to manage these challenges. The successful implementation of this concept requires cross functional collaboration among relevant fields, and among them, closed loop supply chain is an essential domain. The paper aims to highlight some misconceptions concerning the closed loop supply chain, to discuss different challenges, and in addition, to show how the proposed concept deals with those challenges through analysis of key performance indicators (KPI).MethodsThe work presented in this paper is mainly based on the literature review. The analysis of performance of the closed loop supply chain is done using system dynamics, and the Stella software has been used to do the simulation. Findings The results of the simulation depict that in ResCoM; the performance of the closed loop supply chain is much enhanced in terms of supply, demand, and other uncertainties involved. The results may particularly be interesting for industries involved in remanufacturing, researchers in the field of closed loop supply chain, and other relevant areas. Originality The paper presented a novel research concept called ResCoM which is supported by system dynamics models of the closed loop supply chain to demonstrate the behavior of KPI in the closed loop supply chain.

1D photonic band formation and photon localization in finite-size photonic-crystal waveguides
- 2010

Tidskriftsartikel (refereegranskat)abstract
- A transition from discrete optical modes to 1D photonic bands is experimentally observed and numerically studied in planar photonic-crystal (PhC) L-N microcavities of length N. For increasing N the confined modes progressively acquire a well-defined momentum, eventually reconstructing the band dispersion of the corresponding waveguide. Furthermore, photon localization due to disorder is observed experimentally in the membrane PhCs using spatially resolved photoluminescence spectroscopy. Implications on single-photon sources and transfer lines based on quasi-1D PhC structures are discussed.

Spatially resolved structural and chemical properties of the white layer in machined Inconel 718 super alloy
- 2024

Ingår i: Materials and Design. - 0264-1275. ; 239

Tidskriftsartikel (refereegranskat)abstract
- Inconel 718 is one type of nickel-based alloy used for a large range of applications, including gas turbines and aeroengines components. Although mechanical and thermodynamic properties of this material have been deeply studied in the past years, a method able to investigate local properties of the thin white layer formed on the alloy surface after machining remains challenging. Here, a 90 nm X-ray beam is used to probe the local strain, crystal orientation, and chemical composition of grains in the white layer. Data reveals mosaicity induced by the tool during machining. The high spatial resolution, combined with crystal lattice sensitivity, shows that the average grain size is around 30 nm throughout the white layer, while the strain is anisotropic nearest to the surface. Results provide new insights on the basic properties of the white layer in super alloys, revealing important information about the impact of finish machining which might help to explain fatigue and cracking formation on these materials during their usage phase.

Of milk and mobiles: Assessing the potential of cellphone applications to reduce cattle milk yield gaps in Africa using a case study
- 2021
-
Ingår i: Computers and Electronics in Agriculture. - : Elsevier BV. - 0168-1699. ; 191
-
Tidskriftsartikel (refereegranskat)abstract
- There are growing expectations that Information and Communication Technology (ICT) applications could help improve on-farm yields amongst smallholder farmers in developing countries, and consequently, food and nutrition security. However, few studies have quantified the actual contribution of ICT applications on farmers’ yields, and these studies predominantly focused on crop production. We assessed the potential of ICT applications to close milk yield gaps among small- and medium scale dairy cattle farmers in Africa. First, we developed a theoretical framework summarizing biophysical and socio-economic constraints that foster milk yield gaps and discussed which constraints can be addressed using ICT applications. Second, using a case study of a feeding advice application for dairy cattle pre-tested with farmers in rural Kenya, we analyzed how much stand-alone the application could contribute to close dairy cattle milk yield gaps. Our findings suggest that ICT applications could help address some existing biophysical and socio-economic constraints fostering milk yield gaps, including data collection for breeding programs, feeding management advice, and facilitating access to markets and capital. Our stand-alone ICT application closed yield gaps by 2 % to 6 % on representative farms. Several factors may explain the limited actual contribution of selected ICT applications to reduce existing milk yield gaps, including the quality of the input data and models used in ICT applications, and more structural constraints that cannot be addressed by digital tools. Therefore, although ICT applications could help address constraints to achieving higher milk yields on dairy farms, a significant contribution to improve yields may only be achieved when conditions surrounding their use are adequate.

A Companion to Birgitta of Sweden and Her Legacy in the Later Middle Ages
- 2019
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- St Birgitta of Sweden (d. 1373) is one of the most celebrated female visionaries and authors of the Middle Ages and a central figure in the history of late-medieval religion. An aristocratic widow, Birgitta left her native country in 1349 and settled in Rome, where she established herself as an outspoken critic of the Avignon Papacy and an advocate of spiritual and ecclesiastical reform. Birgitta founded a new monastic order, and her major work, The Heavenly Book of Revelations, circulated widely in a variety of monastic, reformist, and intellectual milieus following her death. This volume offers an introduction to the saint and the reception of her work written by experts from various disciplines. In addition to acquainting the reader with the state of the scholarship, the study also presents fresh interpretations and new perspectives on Birgitta and the sources for her life and writings.

A Constructive Critique of Religion. : Encounters between Christianity, Islam, and Non-religion in Secular Societies
- 2020. - 1
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- Why do some strategies for critique of religion seem to be more beneficial for constructive engagement, whereas others increase intolerance, polarization, and conflict?Through an analysis of the reasons underpinning a critique of religion in institutional contexts of secular democratic societies, A Constructive Critique of Religion explores how constructive interaction and critique can be developed across diverse interests. It shows how social and cultural conditions shaping these institutions enable and structure a critical and constructive engagement across diverging worldviews.A key argument running through the book is that to develop constructive forms of critique a more thorough and systematic investigation of resources for criticism located within religious worldviews themselves is needed. Chapters also address how critique of Islam and Christianity in particular is expressed in areas such as academia, the law, politics, media, education and parenting, with a focus on Northern Europe and North America. The interdisciplinary approach, which combines theoretical perspectives with empirical case studies, contributes to advancing studies of the complex and contentious character of religion in contemporary society.
