Nematode control remains to be an important challenge in agricultural and health industries, thereby new, efficient and preferably natural ways to engage them are required. Dactylellina haptotyla, a nematode-trapping fungus, forms infection structures called knobs to capture, paralyze and subsequently kill nematodes. In this study, genes involved in the secondary metabolism (SM) were investigated
Background: A “Big Room”, a way of organizing design team members through integration, can be found as one of the tools in the “Lean management” philosophy that made Toyota as a car Manufacturer successful. NCC, one of the largest construction companies in the northern European construction industry, is developing their own Big Room concept under the name of NCC Project Studio to improve building
In laser wakefield acceleration (LWFA) a high intensity laser pulse is used to excite a plasma density wave with an associated electric field. This electric field can be used to accelerate electrons. However, to be accelerated the electrons first of all need to enter the plasma wave. This process is called injection. In this thesis a scheme for injecting electrons into a laser wakefield accelerato
Biodiversity is a big part of the understanding of our life and its surroundings. Only a fraction of the earth’s species are known and many are yet to be found. When describing new species often both molecular and morphological data is needed to fully resolve cryptic taxa. In this study, the diversity of two Diptera families, soldier flies (Stratiomyidae) and thick-headed flies (Conopidae), have b
Examensarbetet undersöker möjligheten att låta avbördningskapaciteten – det vill säga sambandet mellan vattennivå och vattenföring – vara vägledande för bedömning av underhållsbehovet i åar och diken. Den potentiella nyttan av en sådan metod bedöms vara hög då den skulle kunna minska frekvensen av omotiverade underhållsinsatser som påverkar vattenmiljön negativt. Arbetet utgår från ett dikningsförThis master thesis project investigates the possibility of using stage–discharge relationships for evaluation of river maintenance demands. In Sweden, the potential benefit of this type of methodology is considered high, in order to prevent unnecessary maintenance activities which are harmful for the aquatic environment. The study is focused on a ditching organization in Höje River in southern Swe
Considering numerical competency in the animal kingdom, primates are thought to be the most advanced ones. Many different studies have showed that also other species such as birds, fishes and amphibians are capable of counting objects and that this ability may be one of the most sophisticated key features for survival. Some lab experiments have revealed that given sufficient amount of training man
Through different blogs, social medias and apps people are sharing pictures like never before. Sales in expensive DSLR cameras have increased, and companies in the photo industry are providing customers with lessons to help them in their quest to become better photographers. From being just an object symbol of tourism it has evolved into becoming a lifestyle for many photography enthusiasts. This

Polyhydroxybutyrate-co-valerate (PHBV), a biodegradable biopolymer, holds promise as a sustainable alternative to petroleum-based plastics. In this study, PHBV was biosynthesized and extracted, followed by an extensive evaluation of various downstream purification methods focusing on surfactant-based washing protocols. Different conditions of sodium dodecyl sulphate (SDS) washing varying in temper
Chemical waste from industrial processes poses a significant environmental challenge, often resulting from inefficient synthetic routes that involve excess reagents and ineffective methods. The principles of atom and step economy have become central to modern synthetic strategies, aiming to minimize waste and maximize molecular efficiency. In this context, photo-redox catalysis has emerged as a co
I sverige använder man främst geologisk kartering, geofysik och borrning som prospekteringsmetoder, men forskning och internationella fallstudier visar att grundvattnet är en outnyttjad informationskälla som kan göra letandet efter malm både träffsäkrare och mer hållbart. När mineraliseringar vittrar läcker exempelvis metaller som koppar, zink eller litium ut i grundvattnet och sprids med flödet. In Sweden, geological mapping, geophysics, and drilling are primarily used as exploration methods, but research and international case studies show that groundwater is an untapped source of information that can make the search for ore both more accurate and more sustainable. As mineralisations weather, metals such as copper, zinc, or lithium leach into the groundwater and are transported with the
Methods for synthesis of peptides using solid phase peptide synthesis (SPPS) are hampered by relying on large amounts of hazardous substances such as dimethylformamide (DMF) as solvent for peptide assembly and trifluoroacetic acid (TFA) a per/polyfluoroalkyl substance (PFAS) as reagent/solvent for side chain protecting group (PG) removal and peptide resin cleavage. Advances have been made towards
To simulate subcutaneous injection pressure, numerical solvers are developed and subsequently used to train a predictive, data-driven surrogate model that delivers fast and reliable outputs. Different approaches are examined for solving a nonlinear partial differential equation that describes the pressure during subcutaneous injections over time and in a semi-infinite spatial domain. For the spati
This thesis focuses on two primary parts: the design of a 10-bit medium high-speed, high-linearity current-steering digital-to-analog converter (DAC), and the implementation of a linear analog interpolation technique aimed at suppressing images at the DAC output. Design considerations for the current-steering DAC are discussed comprehensively, and the circuit is designed in 22nm Fully-Depleted Si
Following approximately three decades of rapid economic growth since the 1980s, in China, more attention has been paid to the sustainability of economic growth. Since 2010, as the main actors of economic activity, Chinese enterprises must face stricter regulatory and policies driving them toward greener transformation. Based on this background, this study will discuss the effect of top management
Youth crime is a significant social problem, and preventive work targeting young people at risk of criminality is currently of central importance. This study examines how the new Swedish Social Services Act (2025:400) influences preventive social work in relation to risk and protective factors. By exploring social workers’ experiences, this study aims to contribute to a deeper understanding of pre
