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

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

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

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

Grön vätgas har lagts fram som en lösning på en av vår tids största utmaningar: Att klara av världens energiförsörjning samtidigt som de fossila bränslena avvecklas. Framför allt i sektorer som industriell kemikalieproduktion och långdistans-transport, där övergången till förnybar elektricitet är svårare. Grön vätgas produceras genom elektrolys, där en elektrisk ström driver den annars icke-spontaDue 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

Abstract Title: A breath of fresh air in family business: A qualitative study on non-family CEOs’ experiences in family businesses Seminar date: May 30th 2024 Course: FEKH49 – Business Administration: Bachelor’s degree project in organization.

For range, velocity and angle measurements, radar is a common technique to use, be it in the automotive industry, defense industry, or for medical purposes. Radars can achieve accurate measurements while also being unaffected by weather conditions such as rain, fog, or backlight. In many use cases, it might be necessary to use several radar units, which in turn allows for the possibility of causin

This thesis evaluated the performance of the water balance model BROOK90 for an even aged spruce forest in southern Sweden. The water balance of the forest was modelled from 1950 onwards to find periods and patterns of drought. Moreover, the impact of climate change as well as thinning as a strategy to reduce drought stress on the water balance were evaluated. Hyltemossa, a managed Norway spruce f

Inom vattenhantering och rening används olika processer och teknologier för att säkerställa att vatten är säkert att konsumera och att avloppsvatten hanteras på ett miljövänligt sätt. För att kontrollera dessa processer och säkerställa ett stabilt flöde och en säker process används olika automatiserade system. Dessa automationssystem kontrollerar allt från olika flöden genom pumpar och ventiler, t

För en framgångsrik ”grön omställning”, med ett samhälle och industri som går i samklang med klimatet och miljön, behövs nya tillvägagångssätt, prioriteringar och verktyg. Det blir mer och mer självklart för företag och organisationer att sätta upp mål och arbeta strategiskt för att minska sin klimatpåverkan. Men i ny EU lagstiftning ingår det även att ta hänsyn till biologisk mångfald. Den snabbaThis study presents a systematic overview and mapping of potential metrics for evaluating the impact of forest management on biodiversity in Swedish forestry. The primary approach involves quantitative Life Cycle Impact Assessments (LCIA) as part of Life Cycle Assessments (LCA). Given the increasing need to integrate the impact on biodiversity into complex value chains, the absence of a standardis

Challenges connected to unsustainable practices are becoming more prominent in society and higher education can aid in promoting sustainability. Swedish universities are since 2006 regulated by law to integrate sustainability into their practices, therefore, this thesis uses qualitative analysis to investigate if the law has promoted integration of sustainable development in the syllabi of a Swedi

The 2008 financial crisis exposed significant weaknesses within the global financial system which were mostly attributed to the practices of financialization. This thesis explores the potential of Islamic finance principles to prevent financial crises while offering a more stable and equitable financial framework. A qualitative approach was used in order to conduct interviews with various professi

Acne vulgaris is a widespread skin disease affecting approximately 9.4 % of the population. It arises from four primary factors: increased sebum production, hyperkeratinization, bacterial colonization, and inflammation, leading to both non-inflammatory and inflammatory lesions. Current treatments include topical and systemic anti-inflammatory agents, antibiotics, and retinols, which often have adv
