Biochemical characterization of the barley Xan-m protein involved in chloroplast formation

Grödan Korn och dess betydelse för människan, nu och i framtiden. Grödor är helt nödvändiga för människans fortsatta överlevnad på jorden. Hur vi använder dem, har avgjort mycket genom människans historia. Desto mer vi har arbetat med grödorna, ju fler människor har fått mat på bordet. En enorm uppgift som varit en viktig pusselbit i kampen mot svält och hungersnöd. Dagens gröda är inte den gröd

Arkitektritat åt fler?

I mitt projekt tittar jag på arkitektanvändning bland privatpersoner och undersöker om det går att skapa ett alternativt sätt att nå ut till en grupp som idag inte anlitar arkitekthjälp vid hemrenoveringar. Något som kändes extra aktuellt nu då renoveringstakten bland privatpersoner ökat och vi blivit allt mer begränsade till våra hem. För att få en bättre bild av tankar och beteenden kring hemren

The Effects of Uncertainty on Decision Making Processes regarding Companies’ Carbon Footprint

The purpose of the study is to contribute with knowledge of how uncertainty affects decision making processes regarding carbon footprint. This study explores companies' perspectives on what uncertainties they experience, how these uncertainties affect their decision making processes and how the companies handle these uncertainties. The study’s data is generated through semi-structured intervie

Genomics-driven discovery of novel drug leads in underexplored microorganisms

Underexplored Gram (-) bacteria as a new source of natural products. Microorganisms produce an impressive array of structurally diverse and complex natural products with industrially-important properties. Microbial natural products therefore continue to be an important source of clinical drug candidates. While natural products from a few soil Gram (+) bacteria, together with their biosynthetic pa

Future Electricity Consumption and Wind Power Production in Sweden - Effects of Climate Change

To maintain stability in the Swedish electricity grid, Svenska kraftnät must be able to predict future electricity production and consumption. Earlier this have been done by using historical data. Now the complexity of the system has increased, because the growing amount of electricity from non­dispatchable sources as well as the impact of climate change. Thus using only historical data will give

Coastal Response to Sea Level Rise in Ystad Municipality

Den ökade erosionen till följd av havsnivåhöjningen, orsakad av klimatförändringarna, som läggs på den redan förekommande erosionen kommer få stora konsekvenser. Mark kommer att försvinna där det i dagsläget finns bostäder, vägar, järnvägar, hem för djur- och växtliv, osv. Dessutom leder erosionen till att mark som idag finns tillgänglig för nybyggen i kustnära områden inte längre kommer att existThe globally accelerating sea-level rise poses a problem in coastal areas through, e.g., the erosion of sandy beaches. Due to this, buildings, infrastructure, and other values can be lost, making the future shoreline position important to project in coastal management. One location with historical erosion problems is Ystad municipality in southern Sweden, where the erosive problems are probable to

How did the simple leather wallet end up as an activist tool for change? A qualitative study of young Swedish consumers boycott and buycott behavior of food and drink brands

Thesis purpose: This thesis aims to discover young Swedish consumers' boycott and buycott behavior of food and drink brands by understanding their decisions and participation in these practices. Methodology: This study is built upon a qualitative research design and adopts an abductive approach. A social constructionist viewpoint guides the research to help to get a deeper understanding of yo

En analys av CoClass & BSAB

Syftet med den här studien är att utreda hur CoClass fungerar som ett nytt klassifikationssystem och informationshanteringen i praktiken. Studien ska också undersöka varför det behövs ett nytt klassifikationssystem och även jämföras med det nuvarande BSAB-systemet. Det ska också belysa den hållbara satsningen som CoClass ska generera. Nämligen, hur CoClass är mer sammanhängande och konsekvent än d

3-D impedance networks simulate complex resistivity spectra of sand-pyrite-water mixtures

Characterizing ore deposits or mining dumps in terms of mineral content and grain size remains a challenge. Since the 1950s the induced polarization (IP) method has been successfully applied in ore prospecting. However, reliably interpreting field survey data requires comprehensive laboratory studies to establish a link between the IP parameters from empirical or phenomenological models and the typ

A systematic meta-review: the relationship between forest structures and biodiversity in deciduous forests.

Human activities in deciduous forests over the past centuries have influenced associated species. To reduce extinction risks and mitigate population declines, there is growing interest in forest conservation and restoration, including initiatives by the European Union (EU). For resulting restoration and conservation practices to succeed, it is essential to know which forest characteristics promote

Genombrott i fuktmätning : Ingjutningsbara och trådlösa RF-prober för betong

Mätning av relativ fuktighet, RF, i betong har tagit ett stort steg framåt med hjälp av trådlösa RF-prober som kan gjutas in direkt från start. I ett nyligen avslutat projekt vid avdelning Byggnadsmaterial vid Lunds tekniska högskola har ett mätsystem för RF i betong utvärderats. En av de största utmaningarna var att säkerställa att proberna klarar ingjutning och att de ger tillförlitliga mätninga

Renovera för hela livet. Det är inte bara en fråga för fastighetsägare.

Bostadskrisen slår mot alla generationer – men lösningarna måste vara långsiktiga och inkludera de behov äldre människor har. Det skriver fyra forskare som är verksamma vid institutionen för hälsovetenskaper vid Lunds universitet och tillhörforskningscentret CASE, Centre for Ageing and Supportive Environments.

Global Distribution and Local Variation of Pre-Rain Green-Up in Tropical Dryland

Pre-rain green-up is a distinctive phenological phenomenon observed in arid and semi-arid regions, featuring the sprouting of plants before the onset of the rainy season. This phenomenon indicates the intricate controls of vegetation phenology other than precipitation, yet its global distribution patterns and underlying causes remain unclear. In this study, we used remotely sensed phenology and ra

Resilience of primary healthcare facilities : Experiences from 16 European countries during the COVID-19 pandemic. A mixed-methods study conducted by EURIPA

Background. The role of primary healthcare (PHC) during a pandemic varies across European countries. The coronavirus disease 2019 (COVID-19) pandemic has altered the working practices of family medicine doctors and impacted the resilience of healthcare systems. Objectives. This study aimed to examine European healthcare system responses to the pandemic, focusing on rural and urban differences. Mat

Antisense-mediated regulation of exon usage in the elastic spring region of Titin modulates sarcomere function

Aims Alternative splicing of Titin (TTN) I-band exons produce protein isoforms with variable size and elasticity, but the mechanisms whereby TTN splice factors regulate exon usage and thereby determining cardiomyocyte passive stiffness and diastolic function, is not well understood. Non-coding RNA transcripts from the antisense strand of protein-coding genes have been shown to regulate alternative

TinyFoA : Memory Efficient Forward-Only Algorithm for On-Device Learning

Forward-only algorithms offer a promising memory-efficient alternative to Backpropagation (BP) for on-device training. However, state-of-the-art forward-only algorithms, e.g., Forward-Forward (FF), still require a substantial amount of memory during the training process, often exceeding the limits of mobile edge and Internet of Things (IoT) devices. At the same time, existing memory-optimization t
