The Arctic is facing major environmental changes impacting marine biodiversity and ecosystem functioning. One way of assessing the responses of an ecosystem to these changes is to quantitatively study food web dynamics. Here, we used stable isotope (δ15N and δ13C) analyses of 39 Arctic marine species to investigate trophic relationships and isotopic niches of the West Greenland food web in 2000–20
Boron-carbon (BxC) thin films are potential neutron converting layers for 10B-based neutron detectors. However, as common material choices for such detectors do not tolerate temperatures above 500 °C, a low temperature deposition route is required. Here, we study trimethylboron B(CH3)3 (TMB) as a single-source precursor for the deposition of BxC thin films by plasma CVD using Ar plasma. The effect
Background and aims Little information is available on real-life occurrence of oral thrush in COPD patients treated with ICS. We investigated oral thrush incidence in COPD patients prescribed FDC ICS/LABA therapies and assessed whether it is modulated by the ICS type, dose, and delivery device. Methods We conducted a historical, observational, matched cohort study (one baseline year before and one
This article focuses on coordination between governance actors in higher education. The object of the study is a department at a public university, seen as a multi-project environment. The purpose of this article is to illustrate and analyze project governance as a tool that allows departmental management to coordinate with the authorities, the board and the management at different levels at the u
Handboken har utarbetats som hjälp för intressenter i byggbranschen att tillämpa Eurokodsystemet på murade konstruktioner. Handboken avses bli ett stöd för projektörer och byggare som varit vana vid att använda nationella svenska byggregler, som BKR, i samband med projekt som uppförs i Sverige. Men handboken kan också vara till nytta för bedömning från beställar- och myndighetssidan av projekt som
The early stages in ontogenetic development are described in the co-occurring Sphaerophthalmus alatus (Boeck, 1838) and Ctenopyge (Mesoctenopyge) tumida Westergård, 1922, using fragmentary but otherwise well-preserved material from Bornholm, Denmark. The former species is a senior synonym of Ctenopyge (Eoctenopyge) angusta Westergård, 1922, as has been recently proposed, but the early stages of S.
Joint diseases are often characterized by inflammatory processes that result in pathological changes in joint tissues, including cartilage degradation and release of components into the synovial fluid. The complement system plays a central role in promoting the inflammation. Because several cartilage proteins are known to interact with complement, causing either activation or inhibition of the sys
Periodontal disease is one of the most common inflammatory infectious diseases worldwide and it is associated with other syndromes, such as cardiovascular disease or rheumatoid arthritis. Recent advances in sequencing allowed for identification of novel periodontopathogens such as Gram-positive Filifactor alocis, but its virulence mechanisms remain largely unknown.We confirmed that F. alocis is a
We experimentally subliminally prime subjects prior to charity donation decisions by showing words that have connotations of pro-social values for a very brief time (17 ms). Our main finding is that, compared to a baseline condition, the pro-social prime increases donations by approximately 10–17 % among subjects with strong pro-social preferences (universalism values). We find a similar effect wh
Inom fysiken används ofta hårda sfärer som modellsystem för att beskriva beteenden och strukturer hos grundläggande byggstenar såsom atomer och molekyler. Dessa sfärer kan ses som en samling biljardbollar och kan därav bara organiseras på ett begränsat antal sätt. Med den ökade förståelsen för många komplexa fysikaliska fenomen och den snabbt växande utvecklingen av nya material behövs modellsysteSoft and deformable ionic microgels such as poly(N-isopropylacrylamide-co-acrylic acid), PNIPAM-co-AA, microgels have shown to be a versatile alternative to the already well-established hard sphere model systems. Their tuneable interaction potential makes them well suited as model systems to study the phase behaviour found for particles interacting via a soft isotropic potential. This stems from t
The aim of this study is to understand the mechanisms behind the diffusion of fired bricks in Hellenistic Europe, initiated in the north Aegean in the 4th century BC. To this end, a social diffusion model is used to simulate the available archaeological data pertaining to this process. The starting point in the construction of the model is the assumption that different categories of people contrib
This work is the result of an interest in realizing a study about the difficulties that Swedish students encounter when learning Spanish as a foreign language, levels A2, B1 and B2, when choosing between the tenses the imperfect and the preterit in state verbs and achievement verbs. To obtain material for this study, three different tasks were used. In the first one, the students received a story
In the aftermath of the Arab Spring, conflicts in Egypt and Tunisia over the authority to rule and the role of religion in society raised questions about these societies’ capacity for reconciling differences. In retrospect, the conflicts also raise questions about the theoretical tools used to analyse regional developments. In particular, the ‘post-Islamism’ thesis has significantly changed the de
Orphan drugs designed to treat rare diseases are often overpriced per patient. Novel treatments are sometimes even more expensive for patients with ultra-rare diseases, in part due to the limited number of patients. Pharmaceutical companies that develop a patented life-saving drug are in a position to charge a very high price, which, at best, may enable these companies to further develop drugs for
Diversity in lifestyles and socioeconomic status among European populations, and recent socio-political and economic changes in transitional countries, may affect changes in adiposity. We aimed to determine whether change in the prevalence of obesity varies between the socio-politically transitional North-East European (Łódź, Poland; Szeged, Hungary; Tartu, Estonia), and the non-transitional Medit
Bovine α-lactalbumin (BLA) forms cytotoxic complexes with oleic acid (OA) that perturbs tumor cell membranes, but molecular determinants of these membrane-interactions remain poorly understood. Here, we aim to obtain molecular insights into the interaction of BLA/BLA-OA complex with model membranes. We characterized the folding state of BLA-OA complex using tryptophan fluorescence and resolved res
Moisture penetration around windows and doors is a problem with serious consequences for stud walls and is a common problem regardless of facade systems. The problem has received considerable focus in recent times, as buildings using ETICS (External thermal insulation composite systems) on stud walls have been damaged by penetrating water. In the present paper a robust moisture safe prefabricated
Triple-negative (TN) breast cancers (ER â ' PR â ' HER2 â ') are highly metastatic and associated with poor prognosis. Within this subtype, invasive, stroma-rich tumours with infiltration of inflammatory cells are even more aggressive. The effect of myeloid cells on reactive stroma formation in TN breast cancer is largely unknown. Here, we show that primary human monocytes have a survival advantag
Payments are central for society. Historically, it involved two parties exchanging goods and services for money. Today, payments, with increasing frequency, consist of digital representations of money that are transferred through globally intertwined network. Payments involve many parties such as payers, payment services providers, banks, central banks, telecom operators, mobile handset manufactur
