Under the Paris Agreement, nations have committed to preventing dangerous global warming. Scenarios for achieving net-zero emissions in the second half of this century depend on land (forests and bioenergy) to remove carbon from the atmosphere. Modelled levels of land-based mitigation could reduce the availability of productive agricultural land, and encroach on natural land, with potentially sign

Katalys är ryggraden i många processer i vardagen. Även människokroppen styrs huvudsakligen av katalysatorer. Detta viktiga koncept tillåter oss att på ett miljövänligt sätt konvertera råmaterial som råolja och naturgas till värdefulla och oersättliga produkter, till exempel motorbränslen, läkemedel och agrokemikalier. En katalysprocess drivs av en katalysator, vilket således är en substans som, uNew classes of N-heterocyclic carbene-palladium(II) complexes containing either a vinyl group in different positions or an anthracene tag in the backbone of the N-heterocycle were synthesized and fully characterized. The vinyl based complexes were copolymerized with divinylbenzene to fabricate robust polymer-supported NHC-Pd(II) systems, while the anthracene based complexes were π-stacked onto the

Objectives Preventing adverse events (AEs) after orthopaedic surgery is a field with great room for improvement. A Swedish instrument for measuring AEs after hip arthroplasty based on administrative data from the national patient register is used by both the Swedish Hip Arthroplasty Register and the Swedish Association of Local Authorities and Regions. It has never been validated and its accuracy

Autonomous vehicle functions in safety-critical situations show promise in reducing the risk and saving lives in accidents compared to existing safety systems. Consequently, it is from many perspectives advantageous to be able to quantify the potential benefits of new autonomous systems for vehicle maneuvers at-the-limit of tire friction. Here, to estimate the potential in terms of saved lives and

During the COVID-19 emergency, cities around the world introduced measures to guarantee physical distancing that restricted access to urban parks and green areas, with potentially negative effects on citizens’ health and wellbeing. This study aims at providing insights to manage access to urban green space in physical distancing times, when the risk of crowding should be avoided. Using the city of

Powder Bed Fusion (PBF) is a range of advanced manufacturing technologies that can fabricate three-dimensional assets directly from CAD data, on a successive layer-by-layer strategy by using thermal energy, typically from a laser source, to irradiate and fuse particles within a powder bed.The aim of this paper was to investigate the application of this advanced manufacturing technique to process c

Consumption of organic food products in Spain has not kept pace with the expansion of production. Supporting the consumption of locally-produced organic food would increase the sustainability of food consumption in Spain. The objective of this study is to analyse the policy obstacles to an increase in organic food consumption. Data collection is based on a document analysis of governmental measure

Multilaminering av akustikplattor-låter det bra? Introduktion av nya tillverkningstekniker öppnar upp nya möjligheter för etablerade produkter. Denna pånyttfödelse kan mycket väl resultera i en användning av en större andel återvunnet material, mindre materialåtgång eller nya egenskaper hos produkterna. Bullriga miljöer, låga ljudfrekvenser och intensiva ljud påverkar människor negativt. I naturenSaint-Gobain Ecophon manufactures acoustic ceiling tiles made primarily of glass wool and are interested in exploring the idea of a new manufacturing technique – using thinner layers of material and laminating these together. The possible benefits are, amongst others, the ability to use different kinds of material where they are the most useful, reduced costs, larger amounts of recycled material,

Despite the growing popularity of ginger beer, its production has been very little researched and poorly documented, the literature available regarding this topic being very limited. This thesis aims to fill this gap by exploring the final stages of development of a new alcoholic ginger beer, identify the difficulties encountered during production and evaluate various solutions to overcome them. I

Jämfört med många andra industrier så har byggnadsindustrin halkat efter med att implementera digitala lösningar. I dagsläget är det enbart ett fåtal materialleverantörer och tillverkare som erbjuder en tjänst av så kallade digitala BIM-objekt till sina produkter. Dessa digitala produkt kopior kan nyttjas för flera syften i projektmodeller vilket exempelvis gynnar desing-team och entreprenörer. DeThe construction industry has in general been rather slow in its implementation of new digital solutions compared to other industries. To date, only a handful of material suppliers are offering a service of so-called digital BIM-objects of their products. These 'digital product copies' can be utilized in projects' BIM-models for several purposes, being favorable to the design team and

Hästnäringen i Sverige fortsätter att växa. Ridsporten är en av de mest populära sporterna i Sverige med utövande från nybörjarnivå upp till världseliten. Vid en mätning som gjordes 2016 uppmättes antalet hästar i Sverige till cirka 355 500 stycken. Med många utövande och många hästar i landet kommer en bred handel, en handel som i takt med sportens utveckling också borde öka. Idag omfattas hästThe horse industry in Sweden continues to grow. The equestrian sport is one of the most popular sports in Sweden with performers from beginners level to riders in the world cup. The number of horses in Sweden was in a survey made in 2016 counted to approximately 355 500. With many performers and a lot of horses comes a wide market, a market that should be growing in pace with the development of th

Unmanned vehicles need robust systems to ensure the safety of the vehicle and its environment. Being able to find and avoid perilous situations is paramount to such a system. In this paper we suggest an unsupervised image-based anomaly detection algorithm using a variational autoencoder and a superpixel segmentation algorithm, which is adapted to the maritime obstacle detection task. The algorithm

En allt mer åldrande befolkning och ett större fokus på att hålla sig frisk har lett till ett ökat intresse för naturbaserade produkter som ger lugnande och hälsofrämjande effekter som lätt kan inkorporeras i människors vardag. En molekyl som är intressant för sådana applikationer är avenantramider (AVN): en havrebaserad förening som har uppvisat antioxidativ kapacitet och anti-klåda, antiinflamma

Vår kropp är uppbyggd av biljontals celler, men utan kommunikation och samarbete dem emellan skulle kroppen och dess livsviktiga processer inte fungera. Denna kommunikation äger till stor del rum på cellernas yta, det så kallade cellmembranet, som alltså inte bara fungerar som en barriär mellan cellerna. Här finns nämligen flera olika molekyler och proteiner som sköter en stor del av kommunikationProteoglycans are important macromolecules located on the human cell surfaces. They have many different and important roles in communication between cells. These roles are especially important for cancer development and the survival of tumor cells and these proteoglycans are, therefore, interesting to study. The proteoglycans are made up of a protein core to which glycosaminoglycan chains are boun
