Luddiga styrdokument får lärare att arbeta med magkänslan. Hur påverkar styrdokument lärares arbete med rapportskrivning på gymnasieskolan och universitetet? Vilka faktorer är störst? Finns det några skillnader? Detta är frågor som vi tacklar i denna studie. Vi har upptäckt att studenter på universitetet kommer med väldigt skiftande förkunskaper i just labbrapportskrivande. Därför bestämde vi osSeveral studies have discussed the importance of laboratory work in physics education and the many different areas of learning that this can contribute to. Most of these studies mention the laboratory report to be an essential part of these laboratory exercises. However, close to none of these studies describe how to teach, advise, review, or assess a written laboratory report. Moreover, the gover

Inom matematiken är det ofta intressant att studera olika strukturer, deras egenskaper, och hur man bäst representerar dem. Så kallade ideal av ringar är ett välstuderat område, men en liknande klass av strukturer kallad subalgebror är hittills mindre studerade. I denna text ges grundläggande definitioner och satser relaterat till LAGBI baser som sedan används för att klassificera vissa polynomsubIn this text, we study almost monomial subalgebras using LAGBI bases. We introduce the concept of a LAGBI base and present an algorithm for computing them. We then use this algorithm to find, and present in a table, all polynomial subalgebras with Frobenius number smaller than or equal to ten. We then prove that some patterns observed in this table hold. Lastly we give a proof of what properties i

This thesis examines how the Swedish Armed Forces communicates its visual identity through Instagram, one of the most popular social media platforms today. The purpose is to analyze which visual elements the Swedish Armed Forces use to express their identity, which visual elements appear most in their Instagram posts, and how their existing visual identity manual is reflected on the platform. We a

Mellan 4.80 och 12.7 miljoner ton plastavfall hamnade i haven runt om i världen år 2010. Stora delar av den plast som hamnar i haven kommer från dålig hantering av plastavfall och den vanligaste typen av avfall i haven är mikroplaster. Mikroplaster kan därför finnas i livsmedel som exempelvis salt. Mikroplaster förekommer inte bara i plast, de är överallt, i luften, i marken och även i vårt blod. Large amounts of plastic in the oceans originate from mismanaged plastic waste, and microplastics (MPs) are the most common type of waste. They can be found in household products, such as sea salts. Therefore, monitoring pollution levels is essential to improve marine health and food safety. This study examined the MP levels in salts produced from the North Atlantic and North Seas and analyzed the

The self-expression to empower oneself through fashion and dress is a fundamental aspect of personal identity and challenge of gender norms, particularly for non-binary individuals. As gender norms are social norms that may limit a person's choices of clothing and influence on how to express oneself, non-binary individuals may find it more difficult to find clothing that aligns with their pers

This study confronts the global urgency of sustainability challenges by evaluating the relationship between international trade and sustainable development, with a specific focus on Indonesia. As a nation deeply entangled with environmental issues and heavily dependent on natural resources, Indonesia's sustainability path under the influence of international trade is a subject of crucial i

The emergence of the Internet language has profoundly impacted everyday communication in China. This study examines the integration of Chinese Internet neologisms into everyday language. Through analysis of Baidu Index data and a questionnaire survey, the study explores the extent to which these neologisms have become part of Internet users’ linguistic repertoire. The findings indicate the success

I samband med den globala uppvärmningen har översvämningar, tropiska cykloner, värmeböljor och extrem torka har blivit allt vanligare världen över. De länder som har störst risk för extrema väderhändelser har minst resurser för att återhämta sig efter dem. Små önationer under utveckling och minst utvecklade länder står i synnerhet inför utmaningar när det gäller att hantera klimatkrisens effekter,The consequences of climate change and increasing disasters jeopardise the livelihoods and resilience of some of the world’s most vulnerable countries. Strengthened international efforts to mobilise and allocate additional climate and disaster resilience financing are required to address the needs of the countries that have least contributed to climate change and who currently are at the forefront

Electrification of processes has become the cornerstone of the strategy to decarbonise energy supply, especially in recent years. This study aims to define the main issues underlying the electrification of the European energy mix, especially those caused by an increasing share of intermittent energies. To this end, through a mix of qualitative and quantitative analysis and personal contributions v

Kombinera halvledarmaterial på atomnivå i nanotrådar Genom att växa nanotrådar och samtidigt studera detta med supermikroskop, kan man styra kristallväxten och utveckla nya materialkombinationer för att skapa framtidens material. Så kallade nanotrådar är i en stavform där diametern är i nm-skalan medan längden kan vara i µm-skalan. Dessa nanotrådar kan vara gjorda av kristallina material och genOne of the ways to utilize III-V nanowires, is to make use of the possibility to combine materials and create heterostructures which allows for creating material combinations with new properties. A special interest can be taken into Sb-containing nanowires due to the high electron mobility, however there has been reported difficulties with switching to other materials because of a 'memory effe

Acute myeloid leukemia (AML) is characterized by an accumulation of immature blast cells, which outgrow the bone marrow and suppress normal blood formation. The condition is associated with poor survival, mainly caused by relapsed and refractory disease. Hence, new therapeutics are needed. Recently, SLC40A1 was identified as potentially important for AML cells in a pooled CRISPR interference scree

The possibility that detected substructures in protoplanetary disks, such as gaps, rings and cavities, are created by distant protoplanets has prompted an inquiry into the mechanism responsible for their formation. These wide-orbit young bodies are likely to form relatively rapidly in the outer regions of circumstellar disks. Pebble accretion is considered a promising candidate to explain their fo

Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. Reducing these substantial emissions aligns with the objectives of
