Greening trends of primary and managed forests in Lithuania

Primary forests are species-rich, carbon-storing ecosystems that represent natural landscapes without human intervention. In contrast, traditional European forestry practices often involve monoculture plantations aimed at maximizing timber yields, leading to reduced tree life cycles, and affecting the carbon cycle. Despite accounting for less than 3% of forest land in the European Union, primary f

Utilization of Different Wood Materials in Cross-laminated Timber Elements – A Study of Different Configurations

Cross-laminated timber (CLT) is an engineered wood product constructed by combining multiple layers of wood lamellae with adhesives. In the serviceability state, structural timber elements, that are light–weight, are more susceptible to complications regarding the vibration level, than heavier structural elements such as concrete. Contemporary standard practice in the building industry, is to use

Begreppsförståelse i fokus - en analys av uppgifter i gymnasiets fysikläroböcker

I studien undersöks i vilken grad och på vilket sätt läroboksuppgifter i fysik, genom sin utformning, främjar gymnasieelevers begreppsförståelse. Begreppsförståelsen definieras som elevernas förmåga att använda kunskapen i nya sammanhang. Studien betonar lärobokens viktiga roll i att forma elevernas förståelse. Uppgifter som främjar begreppsförståelse bör exempelvis vara varierade och knyta an tilTextbook tasks are a critical part of physics education as they build a wide range of skills necessary for mastering the subject. This study evaluates the nature of tasks in three widely used Swedish high school physics textbooks, focusing on whether they enhance conceptual understanding or are primarily aimed at memorization of facts and procedural use of formulas and physical relationships. The

The Ocean and Us - An exploratory qualitative interview study on ocean-society relationships in the Maldives

The ocean’s importance for human survival is indisputable. However, humanity's continuous impact on the ocean negatively affects its well-being. While this interrelation is acknowledged, only a few studies research the relationship between the ocean and societies. Thus, this study aimed to explore whether specific concepts and theories are necessary when analysing ocean-society relationships.

Battery Energy Storage System Size Optimization for Energy Shifting and Constant Power Delivery - the benefits of the System Integration with Solar Farms in Sweden

This master's thesis, in collaboration with Comsys AB, examines the optimal size of a Battery Energy Storage System (BESS) for two services - energy shifting and constant power delivery across the four price areas SE1, SE2, SE3, and SE4 in Sweden. For energy shifting applications, the optimal storage capacities were found to be 20 MWh (2 MWh/MW) in SE1, SE2, and SE4. However, a 0.5 MWh/MW stor

Fastighetsägares arbete med platssamverkan i utsatta områden

Platssamverkan aktualiserar en rad aktuella ämnen, såsom arbete med social hållbarhet, segregation och gentrifiering. Polisens lista över utsatta områden påverkar ett område, och det är något som fastighetsägare måste ta ställning till. Många fastighetsbolag arbetar med platssamverkan men ännu finns inte mycket forskning på vilka effekter frivilliga former av samverkan har och hur fastighetsbolag Place-based collaboration raises various contemporary issues, including efforts towards social sustainability, rising segregation, and gentrification. The Swedish police's identification of vulnerable areas impacts localities, prompting property owners to respond. While many property companies engage in collaboration, research on the effects of voluntary collaboration and the diverse approache

A mapping study of employee-driven innovation: Suggesting future avenues of research

Eftersom innovation ger konkurrensfördelar, ökar marknadsandelar och påskyndar den övergripande institutionella tillväxten, utgör innovation en erkänd framgångsfaktor för organisationer. Under det senaste decenniet har ett paradigmskifte från traditionella innovationsstudier, med fokus på forskning och utveckling, till medarbetardriven innovation (EDI) skett. Då den senaste litteraturkartläggningeInnovation is widely recognized as a critical factor of organizational success as it cultivates competitive edge, augments market share, and accelerates overall institutional growth. During the last decade, a paradigm shift from the traditional innovation studies, focusing on research and development (R&D), toward employee-driven innovation (EDI) has been observed. However, the last literature

The lifecycle of gas in high redshift galaxies

På senaste tiden har flera bilder på galaxer från James Webb Space Telescope (JWST) uppmärksammats. Spektakulära bilder på olika galaxer i alla dess former visas upp och allmänheten kan beundra allt det vackra i Universum. I och med att det ljus som kommer till oss från dessa galaxer har färdats ett visst avstånd, kan man säga att ju längre bort vi observerar - desto längre bak i tiden ser vi. DThe details of galaxy formation are still an unsolved problem in astrophysics. Even though significant progress has been made in simulations and observations, it remains an unsolved issue to describe the complexity it yields. One of the reasons for this is the vast dynamical range in space and time. The smallest scales, where star formation occurs, are connected to the larger scale structure of th

This approach not only mitigated issues linked to bounded rationality but also facilitated communication and decision-making through the interplay of technology and humans. However, the implementation also intr

Design and Synthesis of C7-N-acetylneuraminic Acid Analogues as Potential Bacterial Sialic Acid Transport Inhibitors

I duellen mellan människor och bakterier har båda ett par ess i rockärmen. Människan har utvecklat läkemedel som hämmar bakteriens förmåga till att föröka sig och sprida infektionen vidare. Bakterien i sin tur har utvecklat knep för att komma undan. Under de senare åren hör vi allt oftare om antibiotikaresistens, det vill säga infektioner som inte längre svarar på vanlig behandling och vi behöver This project is part of a larger effort to design bacterial sialic acid inhibitors based on sialic acid, Neu5Ac. The emergence of antimicrobial resistance is a major concern for the public health and causes a significant number of deaths globally each year. There is an urgent need to discover novel antibacterials to still be able to cure infections in the future. This project explores a strategy b
