Textbook 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’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.
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
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
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 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
The case company responded to rising uncertainties, such as supply chain disruptions, with a novel process incorporating crucial technology, emphasizing holism, transparency, and consensus. 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
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
In humanitarian settings, Gender-Based Violence (GBV) is a cause of human rights violations, notably affecting women in vulnerable situations. Migration crises, particularly those leading to the displacement of individuals, further aggravate the vulnerability of women. Recent years have seen a feminization of migration, marked by the higher influx of women migrating, highlighting the need for grea
Due to increasing global energy demands and a need to move away from non-renewable energy sources, green hydrogen is now being considered as a possible replacement for fossil-based energy sources. Especially in “hard-to-abate” sectors, such as steel and petrochemical production, and long-distance transport, where the change to renewable electricity is more difficult. Green hydrogen is produced thr
With rising interest rates increasing the cost of capital, businesses are focusing on reducing expenses. Tied-up capital, largely represented by inventory, is a critical cost driver. Therefore, optimizing inventory levels is crucial for controlling capital costs. Inventory levels consist of cycle stock and safety stock. Cycle stock covers average demand during replenishment, while safety stock mit
This article classifies the option hedging strategies of investment banks, explains why dynamic hedges produce hedge errors in imperfect markets, and studies the magnitude and direction of hedge errors produced by different types of options under different hedging strategies. With the help of deep learning models, we predict prices in the next day and actively hedge, overcoming the losses caused b
Denna studie undersöker faktorer som påverkar bildandet av energigemenskaper och utbredningen av eldelning i Sverige. De regulatoriska omständigheterna, samhällsnyttorna och nyttorna utifrån en fastighetsägares perspektiv undersöks genom intervjuer med experter och aktörer inom fastighetssektorn. Resultaten visar att det sker en förändring i vad elanvändare efterfrågar från elsystemet, att flexibi
This study investigated the enzyme BoGal36A, produced by the gut bacterium Bacteroides ovatus. BoGal36A is an alpha-galactosidase, an enzyme that breaks down complex sugars. Unlike most alpha-galactosidases from the GH36 family, BoGal36A appears to cleave internal glycosidic bonds. In this study, the wild-type BoGal36A and mutant W297F was expressed in E. coli BL21 (DE3) cells and purified subsequ
