High temperature sensitivity of Arctic isoprene emissions explained by sedges

It has been widely reported that isoprene emissions from the Arctic ecosystem have a strong temperature response. Here we identify sedges (Carex spp. and Eriophorum spp.) as key contributors to this high sensitivity using plant chamber experiments. We observe that sedges exhibit a markedly stronger temperature response compared to that of other isoprene emitters and predictions by the widely accep

An international study on activated partial thromboplastin time prolongation. Part 1 : Analytical results

Background: Unexpected prolongation of first-line coagulation tests, including activated partial thromboplastin time (APTT), should trigger further work-up by performing mixing tests to elucidate the underlying cause, direct further specific testing and clarify their possible clinical impact. The aim of our study was to assess whether methodological diversity has any impact on the APTT mixing test

An international study on activated partial thromboplastin time prolongation. Part 2 : Interpretative commenting

Background: Providing evidence-based interpretative comments (IC) is an integral task of clinical laboratory professionals. It may be of special relevance for coagulation testing, where pathological first-line tests could trigger more specialized tests. Our aim was to evaluate the quality of ICs provided to the physician in two samples with activated partial thromboplastin time (APTT) prolongation

Blame and Proportionality

The ethics of blame includes conditions determining whether an instance of blame is permissible. One generally recognised condition is that blame should be proportionate. If it is not proportionate, that speaks against its permissibility. All the same, what exactly amounts to proportionate blame is currently under-theorised. In this paper, we aim to amend this. More precisely, we distinguish betwe

Remotely Sensed Herbaceous Rangelands Biomass from African Rangelands : Validation and Uncertainties

This research explores herbaceous biomass estimation in African rangelands through remote sensing, emphasizing challenges and uncertainties. Comparing remote sensing data with ground validation, the study addresses spatiotemporal variations, employing advanced models and validation techniques. Harmonizing and calibrating ground data from four African countries, the research provides insights into

Figurative, Transferred or Extended use? : The Use of Semantic Labels in the First Edition and the Revised Version of the Swedish Academy Dictionary

In this paper, a doctoral study on the description of semantic change in the Swedish Academy Dictionary (SAOB) is presented. The starting point for the study is semantic labels like figurative and in extended use. Five such labels in SAOB are examined, mainly with methods from the cognitive linguistic framework. The results show, among other things, that the most labelled mechanism is metaphor, th

Model-Based State Estimation for Euler–Lagrange Systems and Rigid-Body Robot Control

This article considers state estimation of rigid-body dynamics where the positions q are available to measurement but where the angular velocities ̇or accelerations are not available to measurement. Using a stability-oriented approach to model-based design of state estimation for Euler–Lagrange systems and rigid-body dynamics, state estimation based on position measurement is shown to guarantee se

This article examines how the potato is used as a crisis strategy and future practiceby a group of actors from a youth education center in Skåne, with connections to alternativeagricultural movements, hereunder among others the permaculture movementand the grassroots movement Potatisuppropet. The article is a derivative effectof the dissertation project, Living Alternative Futures: Mobilising thro

Molecular coagulation and thrombophilia

In healthy individuals, a delicate balance between pro- and anticoagulant systems ensures efficient hemostasis and an open vascular system. As sites of vascular damage, a series of procoagulant reactions take place, which are carefully controlled by several anticoagulant proteins. Circumstantial and genetic risk factors increase the risk of venous thrombosis. Circumstantial risk factors are usuall

Development of a Multivariable Model to Predict the Need for Bone Marrow Sampling in Persons With Monoclonal Gammopathy of Undetermined Significance : A Cohort Study Nested in a Clinical Trial

BACKGROUND: Monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma (SMM) are asymptomatic precursor conditions to multiple myeloma and related disorders. Smoldering multiple myeloma is distinguished from MGUS by 10% or greater bone marrow plasma cells (BMPC) on sampling, has a higher risk for progression, and requires specialist management.OBJECTIVE: To develop a

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

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)

A Subpixel Classification of Multispectral Satellite Imagery for Interpetation of Tundra-Taiga Ecotone Vegetation (Case Study on Tuliok River Valley, Khibiny, Russia)

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

Optimizing Remote Sensing Data and Light Use Efficiency Model for Accurate Gross Primary Production Estimation in African Rangelands

This paper focuses on the meticulous selection of optimal remote sensing and climate datasets for Gross Primary Productivity (GPP) estimation in African rangelands. Utilizing Eddy Covariance Flux Tower data, we refine data selection and employ a Light Use Efficiency (LUE) model, with Sentinel 2 for photosynthetically active vegetation quantification, MODIS for Photosynthetically Active Radiation (

SoilTemp : A global database of near-surface temperature

Current analyses and predictions of spatially explicit patterns and processes in ecology most often rely on climate data interpolated from standardized weather stations. This interpolated climate data represents long-term average thermal conditions at coarse spatial resolutions only. Hence, many climate-forcing factors that operate at fine spatiotemporal resolutions are overlooked. This is particu
