There are likely many undiscovered impact structures on Earth, but several challenges prevent their detection, including possible concealment beneath large ice sheets. In recent years, geophysical, geochemical, and microphysical evidence has mounted for a ca. 58 Ma impact structure under the Hiawatha Glacier, northwest Greenland. Here, we report evidence for a second, much older hypervelocity impa
Determination of spatial position of the upper forest line in Khibiny mountains is important to assess its dynamics caused by global environmental changes. Through analysis of high-resolution satellite images and application of the cartographical method we have determined the position of the forest line and its spatial variations, and explained factors influencing its position. This study has resu
OBJECTIVES: The occurrence of hand and forearm disorders related to vibration exposure, adjusted for relevant background factors, is scarcely reported. We analysed the prevalence of such conditions in a large population cohort, stratified by sex, and associations with exposure to vibrating hand-held tools.DESIGN: This is a retrospective cohort study.SETTING: Individuals in the Malmö Diet and Cance
The paper presents an integrated approach for the apportionment of water and sediment sources and pathways in ungauged territories. The approach comprises various elements such as a large-scale semi-distributed hydrological and erosion model (using the SWAT tool), a statistical assessment of regular discharge data, the discrimination of runoff sources using end-member mixing analysis (EMMA), the a
BACKGROUND: Type 2 diabetes (T2D) is a major risk factor for carpal tunnel syndrome (CTS) and trigger finger (TF), but less is known regarding the risk of developing T2D after being diagnosed with CTS or TF. CTS and TF could be early signs of preclinical T2D, and early detection of T2D is crucial to prevent complications and morbidity. Therefore, we investigate the association between CTS/TF and T
The study provides a new assessment of the water balance components of the catchment (evapotranspiration, surface and lateral flow etc., and its spatial distribution and temporal variability) for the transboundary catchment of Western Dvina river within the poorly gaged Russian part of the catchment. The study focuses on modeling the inland flow generation processes using open source data and the
An experimental linear mixture modelling using ground spectroradiometric measurements in the Kola Peninsula, Russia has been carried out to create a basis for mapping vegetation and non-vegetation components in the tundra-taiga ecotone using satellite imagery. We concentrated on the ground level experiment with the goal to use it further for the classification of multispectral satellite imagery th
Climate change is expected to increase woody vegetation abundance in the Arctic, yet the magnitude, spatial pattern and pathways of change remain uncertain. We compared historical orthophotos photos (1952 and 1979) with high-resolution satellite imagery (2015) to examine six decades of change in abundance of white spruce Picea glauca and tall shrubs (Salix spp., Alnus spp.) near the Agashashok Riv
The design of port complexes is a process that requires considering geographical and economic features of the territory. It is necessary to aggregate the characteristics of coastal landscapes, seascapes, artificial elements, dangerous objects, etc. The experience of implementing such projects (for example, in Sabetta) suggests that all participants in the design process need highly precise geograp
Questions: Tree line ecotone regions are expected to respond swiftly to climate changes. In this paper, remote sensing- and ground-based tree population data are used to examine past and on-going changes of the tree line ecotone in a sub-arctic region characterized by precipitation increase. Questions addressed are: (1) at what rate has the tree line ecotone changed since the mid-20th century; (2)
The vegetation at and beyond the northern edge of the world's boreal forest plays an important though imperfectly understood role in the climate system. This is particularly true within Russia, where only a small proportion of the boreal land area has been studied in depth, and little is known about its recent evolution over time. We describe a long-term collaboration between institutions in Russi
Climate change has the potential to impact headwater streams in the Arctic by thawing permafrost and subsequently altering hydrologic regimes and vegetation distribution, physiognomy and productivity. Permafrost thaw and increased subsurface flow have been inferred from the chemistry of large rivers, but there is limited empirical evidence of the impacts to headwater streams. Here we demonstrate h
The tundra–taiga ecotone plays significant role in northern ecosystems. Due to global climatic changes, the vegetation of the ecotone is the key object of many remote-sensing studies. The interpretation of vegetation and nonvegetation objects of the tundra–taiga ecotone on satellite imageries of a moderate resolution is complicated by the difficulty of extracting these objects from the spectral an
This chapter examines how three parties of the radical right reinterpret the Nordic welfare model to serve a nativist purpose. These parties are the Danish People’s Party (Dansk Folkeparti, DF), the Finns Party (Perussuomalaiset/Sannfinländarna, PS), and the Sweden Democrats (Sverigedemokraterna, SD). The period under analysis stretches from 2009 to 2019, which saw the electoral consolidation of t
Prästen, psalmdiktaren och folkhögskolepionjären Nikolaj Frederik Severin Grundtvig och den rörelse som utgick från honom kom att spela en central roll för formandet av den danska religiösa och nationella identiteten från mitten av 1800-talet och framåt. Detta är ett känt faktum. Mindre känt är att grundtvigianismen även kom att få betydelse för katolsk identitetsformering i Danmark och indirekt ä
This chapter presents the notion of spatial justice as a way of considering the relationship between law and street art in a manner beyond the legal/illegal dichotomy. Through a series of empirical examples, it is demonstrated how street art literally takes a place already taken and imposes itself in an already appropriated urban public space. Street art thus ´redefines the space in contestation t
Background: Healthy lifestyles are inversely associated with the risk of noncommunicable diseases, which are leading causes of death. However, few studies have used longitudinal data to assess the impact of changing lifestyle behaviours on all-cause and cancer mortality. Methods: Within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, lifestyle profiles of 308,497 ca
Oppositely charged polymer-surfactant systems are expected to interact with formation of coacervate complexes near composition of charge-neutrality. Such behaviour is widely used in formulated products (e.g. household and personal care), where the co-deposition of coacervates and active ingredients on various surfaces is triggered by dilution. A transition towards the use of more sustainable ingre
Background: Most studies infer increasing incidence of proximal humeral fractures (PHF) from the 1950´s until the 1990´s. Recent time trends are less clear. Objectives: Our primary objective was to identify time trends in the age- and sex-adjusted adult incidence of PHF in Malmö, Sweden, from year 1944 until 2020. Our secondary objectives were to describe the variation in incidence according to ag
In microbiology, cell analysis is an important tool for understanding influences on biotechnological production. Using current bulk methods, the secretome cannot be assigned to the corresponding cell. This contribution reports a novel method for cell separation inside microscale droplets. Cells are focused in droplets using bulk acoustic waves before the droplet is split at a bifurcation. For a wi
