Desertification has become an increasing concern in the Sahelian landscape. Initiatives, such as the Great Green Wall (GGW) and Action Against Desertification (AAD) are aimed at reversing the effects of desertification. Using the AAD geographical regions as a reference, the rate of greening was analysed using high resolution Sentinel-2 satellite image data (10m) and compared to Moderate Resolution
En grundvattenundersökning i ett område präglat av vattenrelaterade problem. Staden Cochabamba i Bolivia står inför flera vattenrelaterade utmaningar såsom brist på ytvatten, en ökande vattenanvändning, urbanisering och en sjunkande grundvattennivå. Samtidigt råder det en brist på kunskap angående de processer som påverkar grundvattnet i området. Något som detta examensarbete ämnar att förändra. The Central Valley of Cochabamba is located in the Andes mountain range, Bolivia. This region experiences several water related challenges such as a scarcity of surface water, an increasing water demand, a growing urbanization in groundwater recharge areas, and a declining water table due to intensive groundwater extraction. The valley has been influenced by both alluvial and fluvial depositions t
Denna uppsats undersöker diskursen kring terrorism i USA före och efter händelserna den 11 september 2001 genom en detaljerad analys av årsrapporter till presidenten och kongressen från försvarsministern under perioden 2000-2002. Med hjälp av en teoretisk ram baserad på Piet Hein van Kempens Four Concepts of Security - A Human Rights Perspective, som består utav 4 begrepp: internationell säkerhet,
Byggsektorn står för en stor del av Sveriges klimatutsläpp och har som mål att till 2045 bli klimatneutral. För att klara detta mål krävs bland annat förändringar i materialanvändning, till exempel kan materialet betong i flera fall bytas ut mot KL-trä. KL-trä används idag som stommaterial och monteras ofta utan väderskydd med resultatet att vatten i form av nederbörd hamnar i springor och spalterTo reach Sweden's climate goals changes in the use of materials are required. Concrete can in several cases be replaced with Cross-Laminated Timber, or CLT, as framework material. Today CLT is often installed without weather protection, with the result of water ending up in cracks and joints that are difficult to cover. Based on today’s knowledge there is great uncertainty about what condition
Many modern city centres are struggling with the aftermath of car-centric and consumption-driven urban planning from the last century. This approach has led to widespread vacancies, a lack of green spaces, and unattractive public areas, that fail to offer diverse functions. While many cities have pedestrian-friendly zones, these areas are often dominated by retail spaces that cater primarily to co
Hur kan det som anses värdelöst idag ses som något värdefullt imorgon? Projektet söker efter outnyttjad potential i bortkastade föremål och ifrågasätter rådande kulturella attityder gällande våra materiella resurser. Med en praktisk undersökning och konstnärliga arbetsmetoder kopplas det osammanhängande samman och nya alternativa scenarion framträder. Ett arkiv, en materialbank och en samling skis
Infection, Asthma and Serum Amyloid A Proteins The challenges posed in healthcare by inflammatory diseases like Asthma and Bacterial Infections are numerous due to complex defense mechanisms by the host immune system. Asthma is a chronic inflammatory disease that affects millions of people globally causing wheezing, coughing and breathlessness. However, bacterial infections start as an acute infl
Vita albina-mutanter i korn kan inte skapa ordentliga kloroplaster Albinism i växter beror på att de är oförmögna att skapa någon typ av pigment. Det huvudsakliga pigmentet i växter är det gröna klorofyllet. Klorofyll möjliggör växter att ta upp energi från solen, och befinner sig i organellerna kloroplaster inuti växtens celler. Utan fungerande kloroplaster kan växterna inte skapa något klorofylIn barley (Hordeum vulgare), induced mutations can cause a white albina phenotype with a complete lack of pigmentation in the plant tissues. The chloroplasts are also undeveloped in albina mutants. By identifying the genes carrying the causal mutations, knowledge would be obtained about the genetic machinery involved in chloroplast development and pigment biosynthesis. In this work, I have identif
Intracellulära CD59 proteinerna IRIS-1 och IRIS-2 i hjärnan Tidigare har två nya varianter av CD59 proteinet vid namn ”Isoforms Rescuing Insulin Secretion 1/2” (IRIS-1/2) upptäckts i betaceller inuti bukspottskörteln som bland annat är kroppens insulinfabrik, där de visat sig reglera exporten av insulin ut i blodet. Detta sker via ett protein komplex som kallas SNARE komplexet. Dessa proteiner foRecently, two intracellular isoforms of CD59 were discovered in pancreatic beta cells. They proved crucial for insulin secretion and were named Isoforms Rescuing Insulin Secretion 1 and 2 (IRIS-1 and IRIS-2), whose expression decreased in type 2 diabetes (T2D). IRIS-1 and 2 were found across many different tissues on the mRNA level, including the brain. This Master's Thesis focuses on the role
Background: Estrogen receptor alpha (ERα) is a protein that belongs to the nuclear receptor family. It is regulating the expression of genes involved in cell cycle progression, proliferation, and apoptosis. Approximately 75% of breast cancers express ERα, making it an important target for treatment. Researchers have identified various isoforms of ERα, with the most well-characterized one being a 6
Antibiotics commonly used against Pseudomonas aeruginosa biofilms are believed to elicit the production of reactive oxygen species (ROS) as part of their bactericidal mechanism. Depending on their concentration, ROS can either induce cell death by damaging proteins, lipids, and DNA or cause mutations that can lead to antibiotic resistance. Hence, antioxidant defenses, including catalase enzymes, a
Digital integrated circuits are fundamental to modern electronic devices, with increasing design complexity requiring robust verification methods to ensure error free functionality. This thesis examines the critical role of formal verification in digital Integrated Circuits (IC) design, particularly during the architecture modeling phase. Using a state machine module that controls clock frequency
A mutation in ferrochelatase causes the tiger-like appearance of barley mutants The study of plants provides people with knowledge that can be used for a variety of purposes, including advances in agriculture, food production and nature conservation. Barley is an important crop that was domesticated about 10,000 years ago. It can self-fertilize, rarely crosses with other plant species and a singl
Retinoblastoma Gene's Role in Salamander Superpowers Imagine if humans could regenerate lost limbs or repair damaged organs as easily as changing a worn-out part of a car. Sounds like science fiction, right? Yet, for the salamander Pleurodeles waltl, a creature native to Spain and parts of North Africa, this is just another day in the pond. In our study, we dive into the world of these amphib
Connected to the ongoing global challenges relating to soil fertility loss and food security, there has been a recent upswing of alternative management practices (AMPs) within the agricultural sector. These methods are often focused on maximising soil health by safeguarding the below ground ecosystem and by increasing soil organic content. Consequently, AMPs tend to build resilience towards distur
Moderna lösningar inom Artificiell Intelligens (AI) kan åstadkomma otroliga saker, till exempel OpenAIs ChatGPT med förmågan att besvara nästan vad som helst på ett ögonblick. Kraften hos dessa typer av AI kommer med en baksida, nämligen den enorma energiförbrukningen. Den största boven i detta är det faktum att inuti datorn som modellen körs på så måste data kontinuerligt överföras fram och tillbAs data serves an increasingly central role in trending topics within computation, it has become clear that the Von Neumann architecture of the modern computer is the major bottleneck in terms of energy consumption and latency. Neuromorphic computing is an emerging computing paradigm that seeks to overcome this bottleneck through the unification of memory and logic, analogous to the energy efficie
The construction sector is undergoing substantial growth and there are many challenges to address. One challenge is building defects, which affect the structural integrity and put the structure at risk. A common and intrusive building defect is moisture, which can slowly expand and lead to complicated defect detection. Moisture intrusion can cause many issues in the structure of the building and p
