Sown flower strips are increasingly implemented within agri-environment schemes (AES) to increase functional biodiversity and ecosystem services such as pollination or natural pest control, but their effectiveness in achieving these goals remains poorly studied. We tested the performance of experimentally sown annual flower strips specifically designed to promote natural enemies of aphids a
Future connected vehicles will require high-performance communication technologies for advanced cooperative driving applications such as maneuvering and cooperative perception. mmWave communications can meet the bandwidth requirements of such applications, but the typically harsh propagation conditions of vehicular environments hinder the broad adoption of mmWave devices on cars. Reconfigurable in
In this study, laminar burning velocities (LBV) of ammonia in oxygen-enriched air (oxygen content ranging from 30 to 50 vol%) were investigated under various initial temperatures (298, 323, and 348 K) at a pressure of 1 atm, employing the heat flux method. Our measurements reveal substantial disparities with previously published data primarily obtained using the spherical flame method. The reliabi
Stem cells are unique, undifferentiated cells that have the ability to both replicate themselves and develop into specialized cell types. This dual capability makes them valuable in the development of regenerative medicine. Current development in stem cell research has widened their application in cell therapy, drug discovery, reproductive cloning in animals, and cell models for various diseases.
During the energy crisis in 2022/2023, households across Europe were encouraged to reduce their energy use to contribute to energy sufficiency, sovereignty, and solidarity. This paper explores energy saving heating practices among Swedish single-family households during the energy crisis in 2022. The Energy Cultures Framework is used to investigate how material culture and norms affect practices f
Purpose: Agriculture innovation systems (AIS) examine the complex socio-technical and institutional aspects affecting sustainable agriculture. However, it is predominantly constrained to the formal sector activities in the high-income countries (HICs). The informal sector actors play a major role in the agricultural sector of low- and middle-income countries (LMICs), such as India, by innovating a
PURPOSE: To evaluate patients' vision-related activity limitation before and after bilateral cataract surgery using the German version of the Catquest-9SF questionnaire. SETTING: Hanusch Hospital, Vienna, Austria, and Ophthalmic Clinic, Minden, Germany. DESIGN: Questionnaire development. METHODS: This prospective 2-center study included patients who were scheduled for bilateral cataract surgery an
This thesis outlines the design and construction of an acoustophoretic trapping device with greatly increased capacity and throughput, compared to current commercial systems. In acoustic trapping, a strong, localised acoustic field is generated inside a channel. This field can capture and retain particles against a flow, allowing for nanoparticle purification and enrichment without the need for ul
This paper looks into investigate what consequences an infrastructure project such as high speed railway could have on smaller cities and how those could gain from it without having a station in their own municipality. The study looks into the municipalities of Bollebygd and Ulricehamn in Västra Götaland, Sweden. These two smaller cities were disappointed when the government’s representatives for
The ongoing COVID-19 pandemic affects people worldwide. The policies in response to the virus range from closure of national borders to curfews for entire metropolises, like Paris. While we can expect severe impacts on the world economy, the consequences of the pandemic for local sustainability transitions are entirely unclear. In this exploratory study, we investigate how the current situation af
This is the report for a master thesis work which concerns the challenge of automating a reach stacker. A reach stacker is a vehicle that lifts and moves containers. This report should be seen as a preliminary study which handles automation concepts, simulations and sensors. Research questions answered are: Which areas would benefit most from driver assistance, What kind of control is needed for t
All humans are unique, we have different characteristics and we make different decision. This is a challenge when it comes to modelling human behaviour. The models we design are based on mathematics where there is no room for inconsistencies such that are present in human behaviour. So how do we account for this when we try to model human behaviour in evacuation modelling? Most models provide the
The purpose of this work was to use spatial-temporal analysis for the prevention and mitigation of disease spread. A prototype application was specifically designed to detect territories with a high incidence of cases and a second was used to validate the results. The first algorithm tried to find clustered cases territories and compare them to the smooth average of the previous two years of data
As climate change have become generally accepted as a potential problem, reducing the greenhouse gas emissions and global energy demand has become an important research topic. This have led to an increased interest towards the retrofitting of the existing building stock, including cultural protected buildings. Due to the cultural protection, carrying out major alteration such as exterior wall retr
The features of social media platforms not only enable the communication between citizens and political actors or institutions, in the form of comments, but also help in magnifying citizens’ voices and opinions and facilitating mass mobilization or political protests. The European Union institutions seem to understand the capacity of social media as a locus for citizen engagement, be it activism o
Mesosideriter är sällsynta sten-järnmeteoriter med ett gåtfullt ursprung. Deras ovanliga blandning av skorp- och kärnmaterial har föranlett många bildningsteorier under det senaste århundradet. Några frågor har avsett ursprunget till metallen, huruvida den kom från en annan himlakropp, eller från moderkroppens egen kärna, samt varför det finns så pass lite mantelmaterial. Nedslag har haft en centrMesosiderites are rare stony-iron meteorites with enigmatic origins. Their unusual mix of crustal and core materials have inspired many formation theories over the last century. Some of the outstanding questions have regarded the origin of the metal, whether it came from another celestial body or from within the parent body, and the absence of mantle material. The role of impacts has been central
The ever increasing volume of air transport necessitates new technologies to be adopted by the flight industry to fulfill the requirements of safety, security, affordability, and environmental friendliness while still meeting the growing demand. What we need to achieve this goal is a new type of aircraft cruise control, interconnecting all the onboard active control systems and making more accurat
Objective : To determine the association between health-risk behaviors and a history of sexual coercion among urban Chinese high school students. Design : A cross-sectional study was performed among 109,754 high school students who participated in the 2005 Chinese Youth Risk Behavior Survey. Data were analyzed for 5,215 students who had experienced sexual intercourse (1,483 girls, 3,732 boys). Mul
