Algal blooms constitute an emerging threat to global inland water quality, yet their spatial and temporal distribution at the global scale remains largely unknown. Here we establish a global bloom database, using 2.91 million Landsat satellite images from 1982 to 2019 to characterize algal blooms in 248,243 freshwater lakes, representing 57.1% of the global lake area. We show that 21,878 lakes (8.
Strontium titanate (STO), with a wide spectrum of emergent properties such as ferroelectricity and superconductivity, has received significant attention in the community of strongly correlated materials. In the strain-free STO film grown on the SrRuO3 buffer layer, the existing polar nanoregions can facilitate room-temperature ferroelectricity when the STO film thickness approaches 10 nm. Here we
Habitat preferences and foraging strategies affect population-level space use and are therefore crucial to understanding population change and implementing spatial conservation and management actions. We investigated the breeding season habitat preference and foraging site fidelity of the under-studied and threatened, Baltic Sea population of Caspian Terns (Hydroprogne caspia). Using GPS devices,
Since its origins in the 19th century, the SSE has instantiated a strong focus on the practice of solidarity alongside other political claims, thus supporting the idea that ‘another world is possible’, and economic transformation should accompany shifts in social relations (Laville and Salmon, 2014). However, despite its transformative poten-tial, solidarity has been the ‘silent S’ in the SSE, in
Vertically oriented graphene (VG) has attracted attention for years, but the growth mechanism is still not fully revealed. The electric field may play a role, but the direct evidence and exactly what role it plays remains unclear. Here, we conduct a systematic study and find that in plasma-enhanced chemical vapor deposition, the VG growth preferably occurs at spots where the local field is stronge
This article explores the role of values (Gehman, et al. 2013; Daskalaki et al. 2019) in the emergence and evolution of Grassroots Innovations (GIs) in the context of Argentina GIs are developed by communities as a means to overcome social exclusion while at the same time strive for a better future. GIs experience an intrinsic challenge: while they address social injustice, they are not able to ad
Whilst mission-driven or hybrid organisations take various forms, they allshare the challenge of navigating contradictory goals to combine social and commercial benefits to different degrees (Shepherd et al., 2019). Social Enterprises (SEs) are a form of mission-driven organisation that prioritise meeting social needs by bringing goods, services or other benefits to economically or politically exc
Detta är en sammanställning av arkiv och information som Historiska museet vid Lunds universitet har idag (2022) avseende samiska mänskliga kvarlevor samt gipsavgjutningar som museet förvaltar åt Lunds universitet. I rapporten ingår åtta samiska kvarlevor. Alla kvarlevor är inkomna till Lunds universitet under 1800-talet. Sju av kvarlevorna kommer från den svenska sidan av Sápmi, en kvarleva komme
This article explores complementary currencies (CC) that work on the basis of community credit schemes in Argentina, a country often referred to as a laboratory in terms of monetary exploration. In contrast to alternative community-based monetary systems created in the global North, CC developed in the global South usually pursue the creation of supplementary currency circulation in order to addre
This paper explores the role of co-operative finance in the evolution of financialization of the global economy building upon the Italian context. Whereas financialization of daily life has globally affected many individuals around the world in the last decades (Martin, 2002), this has also re-shaped the role of financial institutions in society. Earlier research has suggested that private banks h
Protein scaffolds direct the organization of amorphous precursors that transform into mineralized tissues, but the templating mechanism remains elusive. Motivated by models for the biomineralization of tooth enamel, wherein amyloid-like amelogenin nanoribbons guide the mineralization of apatite filaments, we investigated the impact of nanoribbon structure, sequence, and chemistry on amorphous calc
The title Diels-Alder reaction gave a mixture of enantiomerically pure adducts with complete norbornane-type monoterpene skeletons. The exo/endo ratio of the products changed from approximately 4:1 at 5° to 2:1 at 165°
PEPCRE is an interactive computer graphics program for the rapid construction, manipulation and display of oligopeptides. Essentially any desired conformation of an oligopeptide can be constructed in a simple and straightforward manner. The program provides various display and output possibilities. It is user-friendly and is written in FORTRAN 77 for use on inexpensive, monochrome graphics termina
The 2-deoxy (7), 6-O-methyl (15), 6-deoxy (22), and 6-deoxy-6-fluoro (31) derivatives of methyl β-d-galabioside (1) have been synthesised. Thus, 7 was prepared by xanthate reduction using tributyltin hydride, whereas 22 was obtained by catalytic hydrogenation of a 6-deoxy-6-iodogalabioside. Regioselective mono-fluorination of methyl 2,3-di-O-benzoyl-β-d-galactopyranoside with Et2NSF3 and subsequen
Two new furanocembranoid diterpenes, crematofuran [(1R∗,11R∗,12R∗)-6,19:11,12-bisepoxycembra-3,6,8(19),15-tetraene] (1) and isocrematofuran [(1R∗,3S∗,4S∗)-3,4:6,19-bisepoxycembra-6,8(19),11,15-tetraene] (2), have been isolated from the Dufour gland secretion of the Brazilian ant Crematogaster brevispinosa rochai. Their structures, including the relative configuration, have been determined by a com
The structures of two fungal norsesquiterpenes containing a diepoxide functionality, isolated from cultures of the basidiomycete Resupinatus leightonii, were elucidated by a combination of X-ray analysis, NMR spectroscopy and molecular mechanics calculations.
In this study, the authors develop knowledge and insights on how the perception of interestingness influences the structure and focus of conversations in entrepreneurial education (EE) research. In particular, the authors elaborate on what is perceived as interesting among different subgroups of EE researchers, and not least, how EE researchers can identify and engage in scholarly conversation wit
