The regional variability in tundra and boreal carbon dioxide (CO2) fluxes can be high, complicating efforts to quantify sink-source patterns across the entire region. Statistical models are increasingly used to predict (i.e., upscale) CO2 fluxes across large spatial domains, but the reliability of different modeling techniques, each with different specifications and assumptions, has not been asses

DNA polymerases make up a family of enzymes responsible for regulating DNA replication and repair, which in turn maintains the integrity of the genome. However, despite intensive kinetic, crystallographic, and computational studies, elucidation of the detailed enzymatic mechanism still presents a significant challenge. We recently developed an alternative strategy for exploring the fidelity and me

Objectives While Mycoplasma genitalium is reported as a common rectal infection among men who have sex with men (MSM), published data refer predominantly to urethral infections. Currently, most guidelines recommend M. genitalium testing from urine in men with symptomatic, non-gonococcal urethritis. Macrolide resistance-associated mutations (MRMs) among M. genitalium have increased during the last

Molecular blood biomarkers are lacking for high-grade (HG) gastroenteropancreatic (GEP) neuroendocrine neoplasms (NEN). To histologically distinguish between neuroendocrine carcinoma (NEC), neuroendocrine tumors G3 (NET G3), adenocarcinoma and MINEN is often challenging. The mRNA-based NETest has diagnostic, prognostic and predictive value in neuroendocrine tumors G1-2 but has not been studied in

Background: Road-traffic noise may influence the development of cardiovascular events such as stroke and myocardial infarction, but etiological mechanisms remain unclear. This study aimed to assess the relationship between long-term road-traffic noise exposure and coronary atherosclerosis in Sweden. Methods: In the Swedish CArdioPulmonary bioImage Study (SCAPIS) cohort, including 30,154 subjects a

In recent years, remote sensing data have revealed considerable potential in unraveling crucial information regarding water balance dynamics due to their unique spatiotemporal distribution characteristics, thereby advancing multi-objective optimization algorithms in hydrological model parameter calibration. However, existing optimization frameworks based on the Soil and Water Assessment Tool (SWAT

The long-term carbon storage capacity of the boreal forest is under threat from the increasing frequency and intensity of wildfires. In addition to the direct carbon emissions during a fire, the burnt forest often turns into a net carbon emitter after fire, leading to large additional losses of carbon over several years. Understanding how quickly forests recover after a fire is therefore vital to

Climate change and land-use change represent a dual threat to terrestrial ecosystem functioning. In the tropics, forest conversion to agriculture is occurring alongside warming and more pronounced periods of drought. Rainfall after drought induces enormous dynamics in microbial growth (potential soil carbon storage) and respiration (determining carbon loss), affecting the ecosystem carbon budget.

Bee-mediated pollination plays a crucial role in sustaining global food production. However, while the demand for these pollination services is increasing, many bee species are in decline. To address this discrepancy, farmers use managed bee species to improve crop pollination. One key factor affecting pollination efficiency is the affinity for the crop of interest (i.e., the extent to which a bee

Japan’s rich archaeological record, supported by well-established chronological and typological frameworks, offers valuable opportunities to investigate prehistoric socio-cultural responses to climate change, although comprehensive studies remain limited. This exploratory paper examines the impact of climatic disruptions—particularly the 8.2 ka event—on Jomon foragers in Kyushu, aiming to develop

Background: Nodal assessment in gallbladder cancer remains challenging, particularly in incidental gallbladder cancer. This understages the number of patients with node-positive disease, resulting in prognostic inaccuracy and insufficient adjuvant treatment. This study aimed to identify risk factors for positive nodes in gallbladder cancer and to compare prognostic discrimination of available noda

The major purpose of this study is to investigate existing users’ intention to be loyal towards a second hand application out of the Theory of Planned Behavior model (TpB). The study investigates intention in relation to both ordinary TpB-factors attitude, subjective norm, perceived behavioral control as well as an additional factor identity-creating community based on previous research and theori

Purpose: This bachelor thesis aims to study how fashion companies in Sweden work with influencer marketing as a tool to strengthen their brand awareness and credibility in social media, and their view on difficulties and risks with the strategy. By investigating the subject we aim to contribute to the knowledge of how companies in the fashion industry can use influencer marketing to strengthen the

Det har uttryckts oro över ungdomarnas ständiga uppkoppling via sociodigitala teknologier och hur detta kan relateras till en upplevd försämring av unga människors välbefinnande. Få studier har fokuserat på totala användningen av både sociala medier och dataspel; eller har utforskat potentiella positiva samband mellan sociodigitalt deltagande (SDP) och ungdomarnas välbefinnande. Syfte: Den aktuellConcern has been voiced about adolescents’ instant connectivity via socio-digital technologies and how that relates to a perceived worsening of young people’s well-being. Few studies have focused on cumulative use of both social media and gaming; and/or exploring potential positive associations of socio-digital participation (SDP) and adolescent well-being. Objectives: The current study aimed to

Vid första anblick ger Villacañas intrycket av att vara en anspråkslös by i centrala Spanien. Den besitter inte de karakteristiska egenskaperna som så många andra byar i Spanien har; det tydliga historiska arvet, gamla byggnader, små krokiga gator och gränder. I Villacañas är det första man möts av, till stor del, övergivna dörrfabriker och industrikomplex. Byns arkitektur är beige, rödbrun och daAt first sight, Villacañas seems like a dull and unassuming village in the centre of Spain. In contrary to so many other Spanish villages, Villacañas doesn’t have a strong and visible historical heritage with narrow streets and old buildings. The first thing that meets your eye, when entering the village, is an avenue of abandoned door factories and industrial complexes. The architecture of Villac
