Bansal, Vaibhav (author), Boersma, JP (author), Schotanus, Jelle (author), Stadtlander, W. (author), de Boer, A.M. (author)There is an imbalance in the nitrogen cycle, mainly caused by an increasingly intensive agricultural sector. This leads to the degradation of nature and the loss of biodiversity. Measures have been taken at European level to reduce the amount of nitrogen emitted by the agricultural sector, but this has caused a backlash as farmers in many...student report 2024

Boersma, Femke (author)The consequences of climate change are becoming more and more visible. A significant cause of this is CO2 emissions; the shipping sector is responsible for 3% of global CO2 emissions. As a result, the Fourth IMO GHG Study 2020 presents pathways to reduce the GHG emission of the shipping industry by 50% by 2050. Recent IMO goals have overtaken...master thesis 2024

Boersma, Charlotte (author)Social cohesion is perceived to be under pressure in the Netherlands, especially in its larger cities. The Covid-19 pandemic has reinforced and deepened the socio-spatial divide between vulnerable urban areas and the rest of the city, which not only affects the residents of the area and of the city, but also starts to affect the cohesion of the...master thesis 2023

Boersma, Caspar (author)Robots can aid in post-stroke motor function recovery and motor learning through the use of haptic feedback during collaborative training. A clear objective in robotic-assisted motor learning is to adapt the haptic feedback to individual users, but personal characteristics are not yet considered in this adaptation. <br/><br/>We investigated the...master thesis 2023

Toet, A.S. (author), van Kuijk, J.I. (author), Boersma, K. (author), Santema, S.C. (author)Future mobility systems will likely incorporate more multimodal journeys. These multimodal journeys integrate multiple modes of transport, and their higher future prevalence highlights the importance of paying attention to the modality transfers within journeys. To carefully facilitate these transfers, we advocate the creation of passenger...conference paper 2023

Wang, J. (author), Yan, Xin ping (author), Boersma, B.J. (author), Lu, Ming jian (author), Liu, Xiaohua (author)Printed circuit heat exchangers (PCHE) are designed to improve heat recovery and energy saving in supercritical CO<sub>2</sub> (S-CO<sub>2</sub>) power cycles. In the current study, a modified channel PCHE is proposed based on the regular straight channel and a zigzag channel. The thermal–hydraulic performance of four different types of PCHE...journal article 2023

Ozmen, Yucel (author), Boersma, B.J. (author)An experimental study was conducted to search the reduction of friction in fully developed turbulent pipe flow using different types of polyacrylamides as friction reducing polymers. Pressure drop measurements determined the friction reduction. Three different polymer types Superfloc A110, Superfloc A130 and Superfloc A150 were used to...journal article 2023

(author)Antiviral signalling, which can be activated in host cells upon virus infection, restricts virus replication and communicates infection status to neighbouring cells. The antiviral response is heterogeneous, both quantitatively (efficiency of response activation) and qualitatively (transcribed antiviral gene set). To investigate the basis of...journal article 2023

Boersma, Isaac (author)The need for more efficient aircraft has spawned the conception of a variety of novel engine and aircraft architectures, such as the combined-cycle engine proposed by researchers at Delft University of Technology. To evaluate the potential benefits of these concepts comprehensively, in-depth performance simulations are required. Furthermore,...master thesis 2022

Boersma, Emma (author)The osteochondral interface is known to smoothly mitigate the stress concentration over the surface area of the subchondral bone, with a structural transition from the cartilage to bone. These sites in the body are exposed to high forces, which makes them prone to failure. To improve the repair strategies, a better understanding of the...master thesis 2022

van Brakel, Rosamunde (author), Kudina, O. (author), Fonio, Chiara (author), Boersma, Kees (author)This paper focuses on two examples of the introduction and use of COVID-19 contact tracing apps in The Netherlands (CoronaMelder) and Belgium (Coronalert). It aims to offer a critical, sociotechnical perspective on tracing apps to understand how social, technical, and institutional dimensions form the ingredients for increasing surveillance....journal article 2022

(author)Production of mature oil fields emits significant amount of CO<sub>2</sub> related to circulation and handling of large volumes of gas and water. This can be reduced either by (1) using a low-carbon energy source and/or (2) reducing the volumes of the non-hydrocarbon produced/injected fluids. This paper describes how improved oil recovery...journal article 2022

(author)In response to the outbreak of SARS-CoV-2, many governments decided in 2020 to impose lockdowns on societies. Although the package of measures that constitute such lockdowns differs between countries, it is a general rule that contact between people, especially in large groups of people, is avoided or prohibited. The main reasoning behind these...journal article 2022

Boersma, Jaap-Willem (author)The main motivation for this research originated from two ambitions, which involve many challenges for which circular solutions have to be developed. First, the ambition of the Dutch government to achieve a circular economy, which also includes a circular construction industry, in the Netherlands by 2050 at the latest. Secondly, in line with the...master thesis 2021

loddo, M. (author), Boersma, Foekje (author), Kleppe, Martijn (author), Vingerhoets, Karin (author)In the late 1990s, the explosion of electronic resources resulted in large-scale digitisation projects amid the need for the preservation of digital information. The KB, National Library of the Netherlands, has been actively involved in these activities. Now, it is proposing better ways to both preserve physical library materials and improve...journal article 2021
