This work presents a multivariable control strategy to regulate nighttime temperature and relative humidity inside a greenhouse, using a pipe heating system and a dehumidification system. The greenhouse is modeled as a two-input two-output (TITO) process with a system identification methodology to calculate low-order linear models. Proportional-integral (PI) controllers with anti-windup are used,

Shared socio-economic pathways (SSPs) and shared policy assumptions (SPAs) are lauded as a common basis for climate scenario research across disciplines, yet they lack essential legal and governance elements that are indispensable when assessing future development pathways. This article sets out to address this shortcoming by explaining the interrelated but distinct features of law and governance

Municipal biowaste has a high potential for agricultural use. However, it requires an additional amendment to increase the nutritional content used during the composting process. The purpose of this study was to investigate the selection of compost-enhancing amendments from municipal biowaste using bibliometric and multicriteria analysis. The municipality of Yopal (Casanare, Colombia) was chosen a

The structural characterization of microgels at interfaces is fundamental to understand both their 2D phase behavior and their role as stabilizers that enable emulsions to be broken on demand. However, this characterization is usually limited by available experimental techniques, which do not allow a direct investigation at interfaces. To overcome this difficulty, here we employ neutron reflectome

Plastics consist of fossil fuels, from both a feedstock and energy perspective and thus need to decarbonise. This thesis maps and explores the framings and technologies that surround plastics decarbonisation and the potential mitigation pathway of carbon capture and utilisation. Here, three of the main findings are presented.By unpacking how EU policymakers understand issues concerning plastics, t

Denna uppsats undersöker det framväxande förhållandet mellan geografiska beteckningar (Geographical Indications, GI) och varumärken inom EU-lagstiftningen, med särskilt fokus på den rättsliga utvecklingen som mynnat ut i förordning 2024/1143. Även om både GI och varumärken utgör immate-riella rättigheter, tjänar de olika syften. Varumärken skyddar främst privata kommersiella intressen och företagsThis thesis explores the evolving relationship between geographical indica-tions (GIs) and trademarks within European Union (EU) law, with a particu-lar focus on the legal developments culminating in Regulation 2024/1143. While both GIs and trademarks are forms of intellectual property, they serve different purposes. Trademarks primarily protect commercial brand identity, while GIs are recognised

Information management is a central part of organizations in today´s society, and critical research is continuously made to assess the reliability of sources. Previous studies have suggested that information with confidential sources tends to be perceived as more credible compared to open sources. The aim of the thesis was to analyze the perceived credibility of information from confidential versu

Forests which form a central part in climate change mitigation strategy of Sweden and as precipitation patterns shift and temperatures rise, understanding the responses of forests to these shifts becomes of paramount importance. Automatic high resolution dendrometers have allowed for the continuous measurement of tree radial stem growth and water dynamics, allowing for the forcings of meteorologic

Forests offer vital ecosystem services but face threats from various stressors, including climate change and insect infestations. The European spruce bark beetle (Ips typographus L.) poses significant risks to Norway Spruce (Picea abies). Early detection of bark beetle infestations is crucial for damage control but challenging with traditional methods. This study aims to utilize modern remote sens

Metabolism plays a crucial role in an animal’s life as it determines the amount of energy that can be allocated to growth, reproduction, and survival. The strategies an individual adopts to manage its energy budget have direct consequences to its fitness. How an animal allocates its energy will determine whether it can ensure its own survival while having a high reproductive success or neglect one

The advent of new technologies for single-cell RNA sequencing analyses has resulted in the discovery that the myeloid compartment in the tumor microenvironment (TME) is far more complex than previously appreciated, and that intrinsic and extrinsic factors in the TME highly influence the immunosuppressive or active states of these cell types. There is now a need to develop multiplex assays to ident

This study analyzes the return to schooling in 22 countries. More specifically, the effect on earnings of receiving a bachelor’s and a master’s degree is estimated by applying a propensity score matching approach on microdata. Unlike many other techniques, propensity score matching addresses selection bias to a higher extent making the estimates of the treatment effect on the treated more reliable

Avian influenza constitutes a remarkable threat to global health. Interaction between wild and domestic ducks in the natural wetlands has been considered one of the potential risk factors for the rapid spread of the avian influenza virus. Tanguar haor is one of the vital wetlands in Bangladesh, a wintering place of millions of migratory birds. At the same time, native farmers raise their domestic

Kanari Domna Mining geosocial data from Flickr to explore tourism patterns: The case study of Athens Social media are providing a new type of geo-tagged data that by processing them, new types of knowledge can be generated and used by decision-makers in different areas including tourism. It includes e.g., identifying touristic areas that are not prioritized or advertised by touristic authorities

With climate change, the frequency in climate extremes such as drought, heavy rainfalls, and extreme temperatures is predicted to increase. These extremes can potentially stress and damage vegetation over large areas, leading to altered carbon cycle, vegetation greenness, albedo, and shifted species composition. This study focuses on two different types of extreme events; frost drought caused by w

Korslimmat trä är ett tämligen nytt material, bestående av korslagda lager av brädor. Produkten tillåter nya byggmetoder och kan ses som ett grönare alternativ till stål och betong. Dess uppbyggnad gör det mer robust och mindre beroende av träets varierande egenskaper för olika geometriska dimensioner. Som ett nytt byggnadsmaterial är dess beteende och karaktär inte lika välstuderat. Med trä som iCross-laminated timber is a fairly new material, composed of layers of timber boards cross-placed. The product allows for new construction techniques and can be seen as a more sustainable alternative to steel and concrete. Its structure makes it more robust and less dependent on the variation in properties of wood for different geometrical dimensions. As a new material, the CLT is not well studied
