Tropiska skogar utsätts för mer intensiva och frekventa torkor. Torkor påverkar tillväxt och kollagring i skogen, samt ökar risken för trädödlighet. Det finns flera hypoteser om mekanismerna bakom dödlighet under torka. Två av de vanligaste är något som kallas kolsvält och kavitation. Det är oklart vilken av dessa två mekanismer som inträffar först i tropiska träd under långvarig torka. ExperimentTropical forests experience more intense and frequent droughts. Droughts affect mortality in trees, growth rate and carbon storage in the forest. There are several hypotheses of the mechanisms behind tree mortality during drought. Two of the most common ones are carbon starvation and hydraulic failure. It is unclear which of these mechanisms occur first in tropical trees during long term drought.

Adaptive reuse of existing buildings as a part of the circular economy principle has become a more common approach to promote sustainable development, due to increasing urban densification and environmental concerns. Ventilation systems, as a major contributor to energy use in buildings, often face complete replacement during building reconstruction, despite their potential for extended service li

In Sweden, climate projections indicate longer growing seasons with more frequent extreme weather events, such as droughts and heavy rainfall, posing significant challenges to existing crop systems. Simultaneously, the sector is under growing pressure to reduce its environmental footprint, especially in response to agricultural nutrients runoff contributing to the eutrophication of the Baltic Sea.

As digital content is taking up more and more space in everyday life, brands increasingly turn to social media platforms like TikTok to engage with audiences, especially young adults. However, with this increase also comes a rise in advertising skepticism and users’ heightened awareness of persuasive tactics employed by brands. As a result, it has be-come essential for brands to appear authentic i

Sweden is a country that prides itself on its mining tradition, contributions to European self-sufficiency and, more recently, its steel transition. It focuses its greening efforts on decarbonizing and automating the steel industry. Meanwhile, destructive impacts on land and biodiversity are largely overlooked. Drawing on the literature on extractivism and on psychoanalytical conceptual literature

Det finns många faktorer som påverkar hur svårlöst en konflikt är. Vi undersöker en av dem, nämligen skuggnätverken, genom att titta på kausalsambandet mellan skuggnätverk och staters olika uppbyggnadsprocesser. Begreppet skuggnätverk är en adaption av Nordstroms ?shadows? ? det vill säga ekonomiska och politiska länkar som på både lokal och internationell nivå rör sig utanför de statliga direktiv

A detailed analysis of the positive parity levels in odd iridium isotopes is carried out with an extended version of the Hecht and Satchler model. A satisfactory description of187-193Ir positive parity states and their electromagnetic properties is obtained by coupling several Nilsson particle configurations to an asymmetric rotor.

Rates of molecular, phenotypic, and lineage diversification typically scale negatively with time interval of measurement, raising longstanding questions about time-dependency of evolutionary processes. These patterns and their potential meaning have recently re-entered evolutionary discussions. In this Perspective, we revisit the general challenges in interpreting rate–time relationships. Much app

Contemporary Nordic building design prioritizes energy-efficient HVAC systems to mitigate carbon emissions. However, this approach underestimates intensifying climate risks, creating critical vulnerabilities as extreme weather and energy/resource scarcity escalate. To address this gap, a free-running building concept, eliminating heating, cooling, and mechanical ventilation, was examined for Nordi

Nowadays, European cities contain more than 70% of the population of the continent and are still growing. This growth tends to put pressure on the challenges that urban areas are already facing. The range of these challenges is wide, such challenges being social, environmental and economical. Air pollution, health issues, increasing heat, integration, social exclusion, loneliness or mobility probl

En viktig komponent i vårt moderna samhälle är plaster och användandet av detta material ökar. Plaster skapas av komponenter som extraheras från petroleum, ett icke-förnybart fossilt bränsle. För en hållbar framtid måste användandet av petroleum minska. Alternativ till petroleum-baserade plaster är bio-plaster. Bioraffinaderier använder idag mindre än 20 % av biomassan för etanolproduktion, överskBioplastics are a promising alternative for petroleum-based plastics that today is on high demand in our contemporary lifestyles. They are made from biopolymers such as polyhydroxyalkanoates (PHAs). Producing biopolymers from waste material feedstock using microbes increases profitability and environmental benefits as well as sustainability for biorefineries. Saccharomyces cerevisiae is a robust m

1 LÄRANDE I LTH Inom den pedagogiska forskningen finns det många exempel på vikten av att lärare fungerar som goda ex- empel för att främja en positiv, konstruktiv och givande lärandesituation. I detta nummer av Lärande i LTH ställs istället frågan om det är möjligt att lärare som fungerat som negativa förebilder faktiskt kan generera en positiv effekt när det gäller kommande generationer av lärar

Introduction: Case–control analyses have shown BARD1 variants to be associated with up to >2-fold increase in risk of breast cancer, and potentially greater risk of triple negative breast cancer. BARD1 is included in several gene sequencing panels currently marketed for the prediction of risk of cancer, however there are no gene-specific guidelines for the classification of BARD1 variants. We pres

Defining minimal standards for data collection is key to creating interoperative, searchable genomic and clinical databases. We highlight here the 1+Million Genomes Minimal Dataset for Cancer, encompassing 140 items in 8 domains to foster the collection of cancer data, inform transnational cooperation and advance precision cancer medicine.

Expanded CAG repeats lead to debilitating neurodegenerative disorders characterized by aggregation of proteins with expanded polyglutamine (polyQ) tracts. The mechanism of aggregation involves primary and secondary nucleation steps. We show how a noncanonical member of the DNAJ-chaperone family, DNAJB6, inhibits the conversion of soluble polyQ peptides into amyloid fibrils, in particular by suppre

BACKGROUND: Prostate-specific antigen (PSA) screening and concomitant treatment can be implemented in several ways. The authors investigated how the net benefit of PSA screening varies between common practice versus “good practice.”. METHODS: Microsimulation screening analysis (MISCAN) was used to evaluate the effect on quality-adjusted life-years (QALYs) if 4 recommendations were followed: limite

A β-decay study of Cu77 has been performed at the ISOLDE mass separator with the aim to deduce its β-decay properties and to obtain spectroscopic information on Zn77. Neutron-rich copper isotopes were produced by means of proton- or neutron-induced fission reactions on U238. After the production, Cu77 was selectively laser ionized, mass separated, and sent to different detection systems where β-γ
