Complex formation between Pd(H2O)(4)(2+) and maleic acid (H(2)A) has been studied at 25 degrees C and 2.00 M ionic strength in acidic aqueous solution. Reaction takes place with 1:1 stoichiometry. The kinetics has been followed by use of stopped-flow spectrophotometry under pseudo-first-order conditions with maleic acid in excess. In the concentration ranges 0.01 less than or equal to [H(2)A](tot)
Previous studies report high and increasing iron (Fe) concentrations in boreal river mouths. This Fe has shown relatively high stability to salinity-induced aggregation in estuaries. The aim of this study was to understand how the speciation of Fe affects stability over salinity gradients. For Fe to remain in suspension interactions with organic matter (OM) are fundamental and these interactions c
The upcoming implementation of the ReFuelEU Aviation Initiative presents both challenges and opportunities for the European aviation sector. Starting January 2025, the EU’s aviation fuel mix must include at least 2% Sustainable Aviation Fuel (SAF), leading to higher operating costs for airlines due to SAF’s higher price than fossil kerosene. Additionally, the entire fuel supply chain will need to
Bioenergy derived from agricultural biomass has potential to phase out fossil energy sources while strengthening the bioeconomy. To estimate the agricultural sector's potential to meet the rising demand for renewable energy sources, it is crucial to understand what motivate farmers to sustainably increasing agricultural feedstock production. Through eight semi-structured interviews, and online
Execution time is an important issue in the field of numerical analysis. Simulations are getting more and more complex and the execution times are rapidly increasing. In the scope of this thesis a time integration library is used to solve initial value problems. The aim of the thesis is to implement and investigate two different approaches to decrease the execution time for the library. The main f
During evolution the human brain has increased drastically in size compared to that of other primates. However, little is known about primate brain development as it is difficult to study human and primate brains in the laboratory due to the scarcity of tissues. Yet, it is essential to study primate brains and understand the molecular features leading to the human brain’s unique cognitive function
Public procurement and the purchasing of goods, services and works comprises about 14% of the European gross domestic product (GDP). Procurement initiatives, guidance and tools therefore can have significant influence to leverage demands for more sustainable and circular products and services. This study explores the current circular public procurement (CPP) landscape, looking at barriers and oppo
"Med tanke på att uppvärmningen redan nått cirka en grad, är de närmaste tio årens beslut, investeringar och andra åtgärder avgörande”, skriver fyra forskare.
Despite a long history and the vast number of applications demonstrated, very few market products incorporate acoustophoresis. Because a human operator must run and control a device during an experiment, most devices are limited to proof of concepts. On top of a possible detuning due to temperature changes, the human operator introduces a bias which reduces the reproducibility, performance and rel
The Sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change represents the state of knowledge of anthropogenic disruption to the climate system, its diverse ecosystem and societal impacts, and the imperative for and challenges of mitigation and adaptation responses. It is foundational for global climate policymaking. This paper examines the place of tourism in AR6 and review
BACKGROUND: Amyloid-β (Aβ) is a normal product of neuronal activity, including that of the aggregation-prone Aβ42 variant that is thought to cause Alzheimer's disease (AD). Much knowledge about AD comes from studies of transgenic rodents expressing mutated human amyloid-β protein precursor (AβPP) to increase Aβ production or the Aβ42/40 ratio. Yet, little is known about the normal expression of Aβ
Widespread increases in iron (Fe) concentrations are contributing to ongoing browning of northern freshwaters, but the driver/s behind the trends are not known. Fe mobilization in soils is known to be controlled by redox conditions, pH, and DOC availability for complexation. Moreover, high sulfate concentrations have been suggested to constrain Fe in transition from soil to water, and declining su
Background: Genome-wide association studies (GWAS) have identified >50 single nucleotide polymorphisms (SNP) in association with estimated glomerular filtration rate (eGFR) and chronic kidney disease (CKD) but little is known about whether the combination of these SNPs may aid in prediction of future incidence of CKD in the population. Methods: We included 2301 participants with baseline eGFR ≥60
Residential gardens can provide pollinator habitat and thus contribute to mitigating declines of insect pollinators. To further improve gardens for pollinators, it is necessary to understand the factors and pathways leading to successful conservation interventions. We studied how the success of two common pro-pollinator interventions, garden meadows and flower plantings, were influenced by gardene
Human activities in deciduous forests over the past centuries have influenced associated species. To reduce extinction risks and mitigate population declines, there is growing interest in forest conservation and restoration, including initiatives by the European Union (EU). For resulting restoration and conservation practices to succeed, it is essential to know which forest characteristics promote
