Circular Unit Cell Gratings for X-ray Dark-Field Imaging

Dark-field imaging has been demonstrated to provide complementary information about the unresolved microstructure of the investigated sample. The usual implementation of a grating interferometer, which can provide access to the dark-field signal, consists of linear gratings limiting the sensitivity to only one direction (perpendicular to the grating lines). Recently, a novel grating design, compos

Beyond Federalism? : Inclusion, Citizenship, and Minorities Without Territory in Myanmar's Spring Revolution

Myanmar’s unofficial minorities encompass diverse religious and ethnic groups excluded from Myanmar’s list of 135 officially recognised “national races.” They face exclusion due to their citizenship status as well as societal prejudices and entrenched discrimination against minority communities. Yet, debates over politics, federalism, and power-sharing in Myanmar primarily concern the relationship

Expression of Stress-Induced Genes in Bronchoalveolar Lavage Cells and Lung Fibroblasts from Healthy and COPD Subjects

Chronic obstructive pulmonary disease (COPD) is commonly caused from smoking cigarettes that induce biological stress responses. Previously we found disorganized endoplasmic reticulum (ER) in fibroblasts from COPD with different responses to chemical stressors compared to healthy subjects. Here, we aimed to investigate differences in stress-related gene expressions within lung cells from COPD and

Evidence for ca. 1 Ga hypervelocity impact event found in northwest Greenland

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

Spatial variability of the forest line in the khibiny mountains (based on remote sensing materials)

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

Risk of hand and forearm conditions due to vibrating hand-held tools exposure : a retrospective cohort study from Sweden

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

Integrated approach to study river fluxes, water and sediment sources apportionment in sparsely monitored catchment

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

Carpal Tunnel Syndrome and Trigger Finger May Be an Early Symptom of Preclinic Type 2 Diabetes

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

Assessment of Water Balance for Russian Subcatchment of Western Dvina River Using SWAT Model

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

Linear spectral mixture modelling of arctic vegetation using ground spectroradiometry

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

Pathways of tundra encroachment by trees and tall shrubs in the western Brooks Range of Alaska

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

Fifty years of tree line change in the Khibiny Mountains, Russia : Advantages of combined remote sensing and dendroecological approaches

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)

Three decades of remote sensing subarctic vegetation in northern Russia : A case study in science diplomacy

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
