Expanding hypoxia in the Baltic Sea over the past century has led to the development of anoxic and sulfidic (euxinic) deep basins that are only periodically ventilated by inflows of oxygenated waters from the North Sea. In this study, we investigate the potential consequences of the expanding hypoxia for manganese (Mn) burial in the Baltic Sea using a combination of pore water and sediment analyse

Mobility particle size spectrometers often referred to as DMPS (Differential Mobility Particle Sizers) or SMPS (Scanning Mobility Particle Sizers) have found a wide range of applications in atmospheric aerosol research. However, comparability of measurements conducted world-wide is hampered by lack of generally accepted technical standards and guidelines with respect to the instrumental set-up, me

Abstract Trying to preserve the forest is an important issue considering its tremendous impact on the ecosystem and subsequently on humans and their lives. On the other hand, humans have changed the area of the forest in different ways. Therefore, investigating the human impact and helping to prevent the destruction of the forest plays a vital role in preserving biodiversity and maintaining ecosys

Retrieving episodic memories often involves reconstructing both their semantic content and the emotional context in which they occurred. However, the neural mechanisms that differentiate these forms of reinstatement remain poorly understood. This event-related potential (ERP) study examines how semantic category and emotional valence are reinstated during memory retrieval.Seventy participants enco

This doctoral thesis presents a comprehensive investigation into action-detected two-dimensional electronic spectroscopy (A-2DES), from the technical development of a state-of-the-art apparatus to its application in elucidating ultrafast dynamics in advanced materials and biological systems. The work is founded on the design and implementation of an A-2DES setup centered on a single acousto-optic

PurposeThe benefit of adding concurrent systemic therapy to definitive radiation therapy (RT) for patients with T1-2 oropharyngeal squamous cell carcinoma (OPSCC) and limited neck node involvement is uncertain. This study investigates whether chemotherapy (CRT) in patients with early-stage (T1-2) low-volume nodal disease (Union for International Cancer Control Seventh Edition N1-2b) improves overa

BACKGROUND: Frontotemporal dementia (FTD) with right anterior temporal lobe (RATL) predominant atrophy is an emerging area of interest. Recent findings by the International Working Group (IWG) have identified this subtype as having a distinct clinical profile within the FTD spectrum (Ulugut et al., 2024, A&D). However, its genetic and pathological underpinnings remain unexplored in large, mult

The interactions between uncharged polymers, e.g. ethyl(hydroxylethyl)cellulose (EHEC) and some model polymers, and ionic surfactants in aqueous solution has been studied by using isothermal titration and differential scanning calorimetry. We found that titration calorimetry could give quite detailed information about polymer - surfactant interactions. Values for the critical aggregation concentra

Strengthening of feed security in the Sahel is urgently needed given the climate change and growing human population. A prerequisite to this is sustainable use of rangeland forage resources for livestock. Many studies have focused on the assessment of rangeland resources during the rainy season, while only a few have focused on the dry season which is the longest and most demanding period for live

Coastal flooding and erosion are worldwide problems that are further aggravated by rising sea levels and increasing population densities in coastal areas. In many of those areas, sandy beaches and dunes protect thehinterland from waves and extreme water levels during storms, while providing natural and recreational values. Sandy coasts are dynamic systems. Thus, risk assessments and coastal manage

Introduction: Elevated pulmonary vascular resistance (PVR) is observed in both physiological and pathological states. Pulmonary hypertension (PH) is a condition associated with significant morbidity and mortality in neonates and children and curative pharmacotherapy is lacking in most cases. In utero, a high PVR allows for blood to bypass the lungs through the open ductus arteriosus (DA). Vascular

Although prior falls are a well-established predictor of future fracture, there is currently limited evidence regarding the specific value of falls history in fracture risk assessment relative to that of other clinical risk factors and bone mineral density (BMD) measurement. We therefore investigated, across the three Osteoporotic Fractures in Men (MrOS) Study cohorts, whether past falls predicted

Groundwater is the general source of drinking water in the Shimabara Peninsula, Nagasaki, Japan, and consequently, occurring nitrate nitrogen (NO3-N) pollution in the groundwater is a significant problem. Although various countermeasures have been implemented, nitrate nitrogen concentrations remain serious. Therefore, it is necessary to evaluate effects of different potentially effective counterme

Old Scots pine (Pinus sylvestris L.) trees provide important habitat structures in boreal forest ecosystems, yet long-term intensive forest management in Sweden has made such trees increasingly rare and difficult to locate across large forest landscapes. Although field-based inventories can identify old trees reliably, they are time-consuming, costly, and spatially limited. This creates a need for

Background: Sedation is often provided to resuscitated out-of-hospital cardiac arrest (OHCA) patients to tolerate post-cardiac arrest care, including temperature management. However, the evidence of benefit or harm from routinely administered deep sedation after cardiac arrest is limited. The aim of this trial is to investigate the effects of continuous deep sedation compared to minimal sedation o

Aim: Allometric relationships, which describe plant growth patterns shaped by environmental conditions, reflect functional trade-offs and represent key functional traits that optimise adaptation, resource acquisition, stress tolerance and competition. Here, we assess how these allometric relationships and associated functional trade-offs drive ecosystem structure, functioning and competitive inter

INTRODUCTION: Total alloplastic replacement of the temporomandibular joint (TMJ) is a viable treatment option for severe TMJ disorders (TMDs) unresponsive to conservative approaches, as well as for reconstruction of congenital or acquired TMJ defects. However, clinical data on indications, outcomes, complications and long-term effects remain limited, and no global registry currently exists. This s
