Collenteur, Raoul A. (author), Bakker, M. (author), Klammler, Gernot (author), Birk, Steffen (author)The estimation of groundwater recharge is of paramount importance to assess the sustainability of groundwater use in aquifers around the world. Estimation of the recharge flux, however, remains notoriously difficult. In this study the application of nonlinear transfer function noise (TFN) models using impulse response functions is explored to...journal article 2021

Liu, Y. (author), Amini-Abyaneh, Arash (author), Hertogh, M.J.C.M. (author), Houwing, E.J. (author), Bakker, H.L.M. (author)Purpose: Management of inter-organizational projects focuses on the collective benefits of a group of organizations on a shared activity for a limited period and the coordination among them. However, how learning is facilitated in the inter-organizational project remains under-developed in the literature. Design/methodology/approach: This...journal article 2021

(author), Koenderink, G.H. (author), Richter, Ralf P. (author), Ensing, Bernd (author), Bakker, Huib J. (author)The biological functions of natural polyelectrolytes are strongly influenced by the presence of ions, which bind to the polymer chains and thereby modify their properties. Although the biological impact of such modifications is well recognized, a detailed molecular picture of the binding process and of the mechanisms that drive the subsequent...journal article 2021

Sumter, Deborah (author), de Koning, J.I.J.C. (author), Bakker, C.A. (author), Balkenende, R. (author)In a recent study, we identified seven key circular competencies for design: (1) Design for Multiple Use Cycles, (2) Design for Recovery, (3) Circular Impact Assessment, (4) Circular Business Models, (5) Circular User Engagement, (6) Circular Economy Collaboration, and (7) Circular Economy Communication. These were derived from small‐scale...journal article 2021

van Dam, S.S. (author), Sleeswijk Visser, F. (author), Bakker, C.A. (author)Designers play an important role in service transformation and the development of product-service systems by applying co-creation methods. This paper presents a case of how we applied co-creation in practice and the impact this has had on developing a circular product-service system. It details the method used in the co-creation process and...journal article 2021

van Altena, V.P. (author), Krans, Jan (author), Bakker, Henk (author), Stoter, J.E. (author)This article examines how GIS can be used as a heuristic tool to reconstruct spatial–temporal events from narratives in order to examine whether a scenario is conceivable within the narrative world. The narrative about Paul's escape from Berea (Acts 17:14–15) is used as a case study. Several interpretive issues related to spatial and temporal...journal article 2021

Bakker, W. (author), Hofland, Bas (author), de Almeida Sousa, E. (author), Oldenziel, G. (author), Overmars, E.F.J. (author)In this paper the development of a high-power pulsed LED line light and its use to apply particle image velocimetry (PIV) during wave impact measurements are described. An electrical circuit that generates high-current pulses is designed and built, which is used to overdrive a number of commercially available LEDs. The limit for this...journal article 2021

(author), Reijngoud, Dirk Jan (author), Bakker, Barbara M. (author)13C-isotope tracing is a frequently employed approach to study metabolic pathway activity. When combined with the subsequent quantification of absolute metabolite concentrations, this enables detailed characterization of the metabolome in biological specimens and facilitates computational time-resolved flux quantification. Classically, a 13C...journal article 2021

Abdu, Rotem (author), van Helden, G. (author), Alberto, Rosa (author), Bakker, Arthur (author)In this paper, we combine dialogic and embodied theories of learning to create a unified analytic lens. Embodied cognition is a theoretical approach operating under the premise that thinking and communication are multimodal activities. Under this premise, dialogue between learners needs to be conceptualized using a multimodal lens. We identify...journal article 2021

Bakker, N.J. (author), Åhman, Hanna Nilsson (author), Burgers, Teun (author), Barreau, Nicolas (author), Weeber, A.W. (author), Theelen, Mirjam (author)Partial shading of monolithically interconnected Cu(In,Ga)Se<sub>2</sub> (CIGSe) modules can lead to the formation of reverse bias induced defects. These localized defects permanently reduce the output of the PV module. The formation and propagation mechanisms of these defects is studied. Understanding these mechanisms can help to prevent or...journal article 2020

Poppelaars, F.A. (author), Bakker, C.A. (author), van Engelen, J.M.L. (author)For the transition toward a circular economy, it is essential that products are returned for reuse, refurbishing or recycling. In order to address the lack of literature on the topic from a user perspective, this paper explores how users can be stimulated to return used smartphones. Taking a Research through Design approach, we developed a...journal article 2020

Ökmen, Ö. (author), Bosch-Rekveldt, M.G.C. (author), Bakker, H.L.M. (author)Scheduling of a construction project can be done by using the Critical Path Method (CPM) in case the project is composed of interrelated activities that can be combined through a network. Given uncertainties nowadays and the related need for project schedule adaptations, the question is raised whether and how “traditional” CPM based schedules...conference paper 2020

van Dam, S.S. (author), Bakker, C.A. (author), Hoogeveen, L.A.J. (author)This paper presents the results of two co-creation sessions with stakeholders in the automotive aftermarket. The sessions were instigated as part of the EU project ReCiPSS to develop a new service to simplify the reverse logistics of automotive cores purposed for remanufacturing. Remanufacturing car parts is a longstanding practice within the...conference paper 2020

Flipsen, Bas (author), Bakker, C.A. (author), de Pauw, I.C. (author)Designing products for the Circular Economy requires closing and slowing of loops by means of repair, reman-ufacturing, refurbishment, parts reuse and/or recycling. Ease of product disassembly facilitates these processes to be more cost-effective, resulting in a better circular strategy fit. In this paper we present the Hotspot Map-ping method....conference paper 2020

Bakker, N.J. (author), Rasia, Alix (author), Assen, Suzanne (author), Aflouat, Basma Ben Said (author), Weeber, A.W. (author), Theelen, Mirjam (author)When a PV module is partially shaded, the shaded solar cells operate in a reverse bias condition. For Cu(In,Ga)Se2 cells this condition can cause defects that irreversibly reduce the output of these cells and the full module. In order to design robust shade-tolerant CIGS modules details need to be known of the conditions at which these...journal article 2020

Giubertoni, Giulia (author), Burla, Federica (author), Bakker, Huib J. (author), Koenderink, G.H. (author)Many biopolymer hydrogels are environmentally responsive because they are held together by physical associations that depend on pH and temperature. Here, we investigate how the pH and temperature responses of the rheology of hyaluronan hydrogels are connected to the underlying molecular interactions. Hyaluronan is an essential structural...journal article 2020

Magnetic resonance imaging (MRI) would be the preferred diagnostic method for infant hydrocephaleus. However, in practice, MRI is seldom used in sub-Saharan Africa due to its high prize, low mobility, and...conference paper 2020

Sumter, Deborah (author), de Koning, J.I.J.C. (author), Bakker, C.A. (author), Balkenende, R. (author)This study addresses what competencies (knowledge, skills, and attitudes) designers need in order to successfully design products and services for a circular economy. Existing literature, though sparse, has identified a number of circular economy competencies for design. Yet, a coherent overview is lacking. To complement the competencies found...journal article 2020
