Laccases are multicopper oxidases capable of oxidizing a broad range of phenolic and non-phenolic compounds, making them attractive biocatalysts for lignin valorization and environmental applications. In this work, two bacterial laccases, LacA from Bacillus amyloliquefaciens and MEK from Psychrobacter sp., were recombinantly produced in Escherichia coli BL21 (DE3), purified, and characterized to s
Introduction: Extractability of shea oil depends on its solubility and so the feasibility of upscaling the extraction method for industrial purposes can be understood by studying sample solubility. Background: Supercritical fluid extraction (SFE) is a greener technique than the current hexane extraction method but has not been utilized in shea oil yet and its solubility in supercritical carbon d
Likvärdig bedömning av elevtexter förutsätter en samsyn bland lärare från olika skolor avseende vilka textkvaliteter som elever förväntas använda i sitt skrivande av specifika texttyper. Syftet med denna studie är att kartlägga sambanden mellan utvalda textkvaliteter och betyg i argumenterande elevtexter från kursen Svenska nivå 1 samt att undersöka om dessa samband är likartade mellan olika skolo
Detta examensarbete undersöker hur ämnesspråk i historia förklaras och används i gymnasieskolans läroböcker och lärarledda undervisning. Arbetet har utförts på en har genomförts i form av en läromedelsanalys av två upplagor av Perspektiv på historien 1b som anpassats utifrån läroplanerna Gy11 & Gy25, följt av en observationsstudie av två verksamma historielärare på en gymnasieskola i södra Sve
The purpose of this essay is to assist teachers of Swedish who are considering using the exemption clause while grading. It does this by describing and charting teachers' perceptions of the exemption clause and its purpose in relation to dyslexia. In-service teachers, who feel uncertain about using the exemption clause, may read how other teachers perceive it, and tailor their own usage accord
This study evaluates the integration of grid-connected solar photovoltaic (PV) and battery energy storage systems (BESS) for medium-scale tea factories in two different regions located in Kenya; Region Central and Region West. Since tea production is both electricity intensive and highly dependent on grid supply, renewable energy technologies can offer opportunities to improve energy reliability a
I föreliggande studie undersöks den kontroversiella skönlitteraturens roll i svenskämnets litteraturundervisning särskilt i relation till skolans värdegrund. Den empiriska undersökningen utgörs av semistrukturerade intervjuer med sex verksamma gymnasielärare i svenska. Intervjuerna analyseras med hjälp av Rita Felskis (2008) samt Björn Bradlings (2020) teoretiska begrepp för att förklara litteratu
This thesis examines the relation between digitalization, in the form of smart cities, and the core-periphery logic, trying to understand how digitalization has affected the narration that shapes regional inequalities, smart city governance and the future of regional development. Through an analytical narrative approach, this research examines policy documents, alongside the case studies of Aizuwa
In recent years, against the backdrop of declining fertility rates, China has shifted toward family policies that encourage childbirth. However, this family policies does not significantly reverse the trend of low birth rates. The thesis drew on 13 semi-structured interviews with married working women in China and, from the perspective of women’s lived experiences, explored the operational logic
This research examines what was at stake for young Chinese women who are negatively conceptualized as fudimo 扶弟魔. Drawing on feminist theories of everyday resistance and relational autonomy, it explores how they resist intersecting gendered power relations in everyday life. The thesis draws on ethnographic methods, including participant observation and semi-structured interviews with 15 women aged
This thesis examines how Chinese international students in Lund, Sweden, rebuild a sense of belonging through eating practices when their expectations of life abroad fail to achieve. Drawing on semi-structured interviews with nine master's students and ethnographic participant observation of a Lantern Festival hotpot gathering, the thesis employs Antonsich`s Analytical framework of belonging a
This paper studies the relationship between Thai-Cambodia border tensions and cooperation against online fraud from February 2021 to February 2026. Online fraud has become a serious cross-border problem in Southeast Asia, and Thailand and Cambodia both have reasons to cooperate against scam compounds and related criminal networks. At the same time, their relationship is shaped by a long history of
This thesis investigates the applicability of using machine learning for demand forecasting at HMS Networks. Using the design science research methodology, multiple forecasting artifacts were developed and tested iteratively, using historical sales data. Four tree-based models; Decision Tree, Random Forest, LightGBM and XGBoost, were tested with different pre-processing and feature engineering tec
Global manufacturing companies operate in increasingly uncertain and complex environments where changes in sourcing strategies, supplier structures and logistics networks create significant challenges for decision- making. Traditional analytical methods often struggle to capture the dynamic and interconnected nature of modern supply chains, limiting their ability to support proactive evaluation

Lignin, the second most abundant biopolymer after cellulose, is a promising renewable material but remains underutilized due to challenges in its dissolution and processing. This study combines a literature review and an experimental investigation to better understand the solubility behavior of kraft lignin in different solvent systems. The literature review analyzed recent studies (2012-2023) on
In this study a development of a GC-FID method to detect adulteration in commercial olive oils based on fatty acid composition and free fatty acid content was conducted. Adulteration of olive oils and especially extra virgin olive oils is a common issue. Due to their popularity and high cost they are often mixed with other vegetable oils or lower quality olive oil for increased profit. Olive oil h
Wind generation’s growing share of Nordic electricity supply has made imbalance settlement an increasingly costly exposure for producers. Under the Nordic single-price mechanism, all residual imbalance is settled at a single imbalance price, regardless of direction, determined by the mFRR activation market. Before that price is known, the producer fixes a day-ahead position, adjusts on the continu
Variations in groundwater levels result from several complex hydrological processes (such as precipitation, evapotranspiration and groundwater-surface water interactions), and the groundwater response depends on factors including topography and physical properties related to the geology of the aquifer. By studying time series of hydrogeological data, such as groundwater levels and precipitation, i
