Salgas, A. (author), Sun, Junzi (author), Delbecq, Scott (author), Planès, Thomas (author), Lafforgue, Gilles (author)The study of the environmental transition of the aviation sector calls for prospective traffic scenarios. Detailed traffic and emissions inventories are often needed to refine the available analyses and to enable the simulation of regionalised scenarios. In the past studies, these are generally based on commercial, proprietary traffic data,...journal article 2024

Noorian Najafabadi, S.A. (author), Ding, Er (author), Hobeika, N. (author), Bluyssen, P.M. (author)Indoor air quality (IAQ) is an important aspect of maintaining human health and well-being, particularly since people spend most of their time indoors. Carpets, with their large surface area and dense fibre piles, have the potential to significantly impact IAQ by emitting and absorbing volatile organic compounds (VOC) from building materials and...journal article 2024

Kumar, Abhinav (author), Gupta, Ankit (author), Anupam, K. (author), Wagh, Vivek Pratap (author)In most of developing countries across the world, pavement design is still based on an empirical approach that may result in premature failure or overdesigned pavements. A shift from an empirical to a semi-mechanistic or mechanistic approach is the need of modern time. In this regard, computational tools such as finite element (FE) are being...journal article 2024

Ferreira, J.P. (author), Ferràs, David (author), Covas, Dídia I.C. (author), van der Werf, Job (author), Kapelan, Z. (author)The paper proposes a novel methodology to locate and quantify entrapped air pockets created during pipe-filling events often found in intermittent water supply systems. Different filling conditions were tested in an experimental pipe with a high point. Measurements were taken and video recordings were carried out to assess air pocket volumes...journal article 2024

Béres, Rebeka (author), Junginger, Martin (author), van den Broek, M.A. (author)To achieve the European Union's goal of climate neutrality by 2050, negative emissions may be required to compensate for emissions exceeding allocated carbon budgets. Therefore, carbon removal technologies such as bioenergy with carbon capture (BECCS) and direct air capture (DAC) may need to play a pivotal role in the power system. To design...journal article 2024

(author)Background: Surgical site infection (SSI) in the form of postoperative deep sternal wound infection (DSWI) after cardiac surgery is a rare, but potentially fatal, complication. In addressing this, the focus is on preventive measures, as most risk factors for SSI are not controllable. Therefore, operating rooms are equipped with heating,...journal article 2024

(author), Luscuere, P (author)Background<br/>The operating room (OR) department is one of the most energy-intensive departments of a hospital. The majority of ORs in the Netherlands have an air-handling installation with an ultra-clean ventilation system. However, not all surgeries require an ultra-clean OR.<br/><br/>Aim<br/>To determine the effect of reducing the air change...journal article 2024

Li, Sihui (author), Peng, Jinqing (author), Wang, Meng (author), Wang, Kai (author), Li, Houpei (author), Lu, C.J. (author)The energy matching of PV driven air conditioners is influenced by building load demand and PV generation. Merely increasing energy performance of building or PV capacity separately may improve the energy balance on a large time resolution, the real-time energy mismatching problem is still serious. In this study, a coordinated optimization...journal article 2024
