In his comment (Kowalski 2023) on our recent publication (Heiskanen et al. 2022) where we present the Integrated Carbon Observation System (ICOS) research infrastructure, Andrew Kowalski introduces three important and, in our opinion, different potential issues in the definition, collection, and availability of field measurements made by the ICOS network, and he proposes possible solutions to thes

Pop-up utställning på Gemla Galleri, Stockholm, organiserad av Möbeldesignmuseum. Utställningen visade ett antal exempel på svenska och internationella möbelklassiker från museets samling. Med utgångspunkt från Anna Wahlöös avhandling Att göra en klassiker (2017) som pågick mellan 231122-231230. .

Impacts of elevated tropospheric ozone on mountain birch leaves reveals higher vulnerability in young leaves compared to old. The leaf recovery after high concentration exposure is affected with lower photosynthetic rate and increased stress-related sesquiterpene emissions.

Sveriges skogar påverkas av de hastiga globala klimatförändringarna. Inverkan av klimatförändringana syns redan med både ökad frekvens och kraftigare extremväder som stormar, värmeböljor, torka och skyfall. Ett tydligt exempel är den extrema torka som drabbade hela landet år 2018. Till följd av torkan har det bland annat skett en explosionsartad ökning av antalet granbarkborrar som angriper och döA changing climate is expected to lead to more extreme weather events, such as an increased frequency of droughts and forest fires. Changing forest conditions can offer benefits to species such as insects, including bark borers that thrive in warm conditions. Warmer temperatures also favor the acceleration of ozone (O3) production, which can cause stress on vegetation. Vegetation stress can have n

Neural induction by cell-cell signaling was discovered a century ago by the organizer transplantations of Spemann and Mangold in amphibians. Spemann later found that early dorsal blastopore lips induced heads and late organizers trunk-tail structures. Identifying region-specific organizer signals has been a driving force in the progress of animal biology. Head induction in the absence of trunk is

Rationale: Cardiopulmonary exercise testing (CPET) is the gold standard to evaluate exertional breathlessness, a common and disabling symptom. However, the interpretation of breathlessness responses to CPET is limited by a scarcity of normative data. Objectives: We aimed to develop normative reference equations for breathlessness intensity (Borg 0–10 category ratio) response in men and women aged

The graptolites of the Tøyen Shale Formation of Kinnekulle in Västergötland, south-central Sweden, are described for the first time and their biostratigraphic distribution is documented from drill core and outcrop material. The faunas indicate an age of mid to late Floian (Billingenian), thus showing a reduced biostratigraphic range of the Tøyen Shale as compared to other areas where this rock uni

Amyloid-β (Aβ) accumulation is critical in Alzheimer disease (AD), and neprilysin is involved in physiologically clearing Aβ. Concerns exist regarding long-term use of sacubitril/valsartan, a neprilysin inhibitor and angiotensin receptor blocker used for heart failure, and its potential to increase AD risk. We evaluated neprilysin inhibition’s effect on AD blood biomarkers in patients with coronar

Mobile Stroke Units (MSUs) are specialized ambulances that can diagnose and treat stroke patients; hence, reducing the time to treatment for stroke patients. Optimal placement of MSUs in a geographic region enables to maximize access to treatment for stroke patients. We contribute a mathematical model to optimally place MSUs in a geographic region. The objective function of the model takes the tra

The Sweden Democrats is a nationalist right-wing populist party with roots in neo-Nazism and white supremacist beliefs. The party has experienced continuous progress during the last decade in Sweden, attracting 20.5 per cent of the vote in the general election of 2022. A combination of discourse analytical methods is applied to study the comment sections of the party's official social media accoun

This paper seeks to reconstruct the worldview informing Iberian overseas expansion during the long sixteenth century, arguing that this worldview was more indebted to Renaissance cosmology than to a recognisably modern scientific worldview. The paper describes how this cosmology provided the intellectual resources necessary to justify overseas expansion to those who doubted its viability and legit
