Measured aerosol size distributions from three measurement stations and modeled air mass trajectory data were combined to study aerosol dynamics in the boreal forest zone in Northern Scandinavia. Three approaches were used: investigation of new particle formation events, analysis of air masses arriving from ocean to continent, and study of changes in the aerosol size distributions when air masses

In this study, we present summertime concentrations and fluxes of biogenic volatile organic compounds (BVOCs) measured at a sub-arctic wetland in northern Sweden using a disjunct eddy-covariance (DEC) technique based on a proton transfer reaction mass spectrometer (PTR-MS). The vegetation at the site was dominated by Sphagnum, Carex and Eriophorum spp. The performance of the DEC system was assesse

The health limit values for PM10 concentration which are presently in force cannot be met on many heavily polluted streets in German conurbations. Soot filters, bans on motorised traffic during certain time periods and areas or for specific vehicle classes, speed limits and other measures are meant to lead to a substantial reduction of the pollution. This article compares the effects of the mentio

The thermal comfort conditions were analyzed for people within a street canyon, a medium sized city in the southern upper Rhine plain, during the summer heatwave 2003. Continuous measurements of all meteorological data necessary to calculate PET that is air temperature Ta, vapor pressure VP, wind speed v, and short and long wave radiation flux densities from the three-dimensional (3D) surroundings

Meteorological investigations were carried out in forests in the southwestern part of the Swabian Alb (SW Germany) to analyze the influences of exposition and silvicultural treatment on the microchmate within various stands of beech (Fagus sylvatica L.). The measurements were taken as part of an interdisciplinary project on the effects of climate and forest management on structures and processes w

Accurate maps of past land cover and human land use are necessary for studying the impact of anthropogenic land-cover changes, such as deforestation, on the climate. The maps of past land cover should ideally be separated into naturally occurring vegetation and human-induced changes, thereby enabling the quantification of the effect of human land use on the past climate. We developed a Bayesian hi

Safety routines such as the WHO surgical safety checklist and SBAR have gained widespread attention and implementation in healthcare. However, there has also been criticism. With the ongoing Covid-19 pandemic, the need for knowledge about how safety routines work in practice is larger than ever. In light of these obstacles, I suggest two approaches to the study of healthcare safety routines, based

Objectives: Gram-positive anaerobic cocci (GPAC) are often regarded as harmless commensals associated with skin and mucosal surfaces. Investigations regarding these bacterial species often concern clinical case reports. In immunocompromised individuals, in the presence of comorbidities, such as diabetes or due to breach of skin barriers, the GPAC can cause infections. Nonetheless, information on t

We consider the Gibbs measure on the configurations of N particles on R+ with one fixed particle at one end at 0. The potential includes pair-wise Coulomb interactions between any particle and its 2K neighbors. Only when K = 1, the model is within the rank-one operators, and it was treated previously. Here, for the case K ≥ 2, exponentially fast convergence of density distribution for the spacings

Urgent water and food security challenges, particularly in continental and boreal regions, need to be addressed by initiatives such as the Horizon 2020‐funded project WATer retention and nutrient recycling in soils and streams for improved AGRIcultural production (WATERAGRI). A new methodological framework for the sustainable management of various solutions resilient to climate change has been dev

During the late 19th and the early 20th century there was an unprecedented development in medical research. Tissue and cell culture rapidly developed into areas with many contributing scientists. The same is true for tissue transplantation. When these achievements are described afterwards in a historical context and a mainline development is constructed, there are researchers whose pioneering work

Background: Gambling within the world of gaming is an emerging phenomenon that may share common conceptual characteristics with traditional forms of gambling. The current literature suggests a higher degree of problematic behaviors in this gambling pattern, but studies are few, prompting for further research regarding individual characteristics and comorbid conditions associated with this activity

Chronic kidney disease (CKD) is frequently accompanied by reproductive health challenges in females and males alike. Progression of CKD is associated with escalating impairment of the hypothalamic–pituitary–gonadal axis, which facilitates evolving ovarian, testicular, and sexual dysfunction. Common clinical reproductive health complications in CKD include abnormal menstruation, impaired sexual hea

Background: There is increasing knowledge of how individual lifestyle factors affect patients with spondyloarthritis, while studies exploring the combination of unhealthy lifestyle factors are lacking. Thus, our aim was to study the frequency of two or more unhealthy lifestyle factors and their associations with physical and mental health in patients with spondyloarthritis (SpA). Methods: A popula

The West Atlantic trumpetfish (Aulostomus maculatus) performs an unusual hunting strategy, termed shadowing, whereby a trumpetfish swims closely behind or next to another ‘host’ species to facilitate the capture of prey. Despite trumpetfish being observed throughout the Caribbean, observations of this behaviour appear to be concentrated to a handful of localities. Here we assess the degree of geog
