Signal is a very important part of the railway. If you place a signal or a different object which is also important in the wrong place, can mean increased safety risks. To ease the work of the consultants in the creation of operational site drawings, the aim is to develop an action plan for the creation of a database, which in turn will be used to create a tool that can be used to automate the pro

Atmospheric new particle formation (NPF) is an important phenomenon in terms of global particle number concentrations. Here we investigated the frequency of NPF, formation rates of 10 nm particles, and growth rates in the size range of 10–25 nm using at least 1 year of aerosol number size-distribution observations at 36 different locations around the world. The majo
Summer greetings from the Director Time flies. It seems like yesterday when nature was painted in shades of brown and grey and we were gradually recovering from the pandemic. Now nature shows its best face – lush and an amazing display of color. At the same time, it feels that we have taken a step back since most of us are affected by yet another new lock-down, but for a very different reason. The

Decomposition of soil organic matter (SOM) in permafrost terrain and the production of greenhouse gases is a key factor for understanding climate change-carbon feedbacks. Previous studies have shown that SOM decomposition is mostly controlled by soil temperature, soil moisture, and carbon-nitrogen ratio (C:N). However, focus has generally been on site-specific processes and little is known about v
The carbon cycle of the terrestrial biosphere plays a vital role in controlling the global carbon balance and, consequently, climate change. Reliably modeled CO2 fluxes between the terrestrial biosphere and the atmosphere are necessary in projections of policy strategies aiming at constraining carbon emissions and of future climate change. In this study, SMOS (Soil Moisture and Ocean Salinity) L3
We have estimated the activation energy for aromatic oxidation by compound I in cytochrome P450 for a diverse set of 17 substrates using state-of-the-art density functional theory (B3LYP) with large basis sets. The activation energies vary from 60 to 87 kJ/mol. We then test if these results can be reproduced by computationally less demanding methods. The best methods (a B3LYP calculation of the ac
The performance of three different backpack-mounted γ-radiation survey systems has been investigated. The systems are based on a LaBr3:Ce detector and a NaI(Tl) detector both with active volume dimensions of 76.2 mm in diameter and 76.2 mm length and a 123% relative efficiency HPGe detector. The detection limits of the systems were tested in a controlled outdoor environment in Sweden, followed by
CD83 is one of the best-known surface markers for fully mature dendritic cells (mature DCs), and its cell-type- and maturation-specific regulation makes the CD83 promoter an interesting tool for the genetic modulation of DCs. To determine the mechanisms regulating this DC- and maturation-specific CD83 expression, chromatin immunoprecipitation (ChIP)-on-chip microarray, biocomputational, reporter,
Little is known about the variation within and among species of long-distance migrants in behavioural strategies and habitat choice on their non-breeding grounds. We report results from regular ringing operations carried out during the winter seasons 2009–2013 and transect counts in 2013, 2015 and 2016 in the Sudan Savanna Zone in Ghana. The best supported capture–mark–recapture model included spe
The Hans Tausen drill site was requested to be on a local dome, as high as possible, with a simple flow pattern and with an undisturbed flow pattern even close to bedrock. The first mapping of the surface elevation was performed as part of a general mapping of the elevation and gravity over Greenland. Later, NASA performed a few overflights of the ice cap. Combining the passes, it was possible to
This work assesses the ability of transradial amputees to discriminate multi-site tactile stimuli in sensory discrimination tasks. It compares different sensory feedback modalities using an artificial hand prosthesis in: 1) a modality matched paradigm where pressure recorded on the five fingertips of the hand was fed back as pressure stimulation on five target points on the residual limb; and 2) a
Background: Most commonly, volume measurements are used to evaluate the effect of lymphedema treatment, but as the accumulation of lymph fluid can be local, this method may not always be the best. Tissue dielectric constant (TDC) can be applied to identify local lymphedema changes, but has not been used before when evaluating treatment in mild arm lymphedema. Thus, the overall aim of this study wa

A strategy for generating potential galectin inhibitors was devised based on derivatization at the C-3′ atom in 3′-amino-N-acetyllactosamine by using structural knowledge of the galectin carbohydrate recognition site. A collection of 12 compounds was prepared by N-acylations or N-sulfonylations. Hydrophobic tagging of the O-3 atom in the N-acetylglucosamine residue with a stearic ester allowed rap
I had the opportunity to work with the flood plain community: Nossa Senhora das Gracas in the Amazon in Brazil. During a month long stay I observed the daily life of the people. A life where the inhabitants shape their daily routines after the rising and dropping Solemoes river. Solemoes is a part of the Amazon river. I identified a need of harvesting water during the low water season, when the r

Endogenous programs that regulate annual cycles have been shown for many taxa, including protists, arthropods, fish, mammals and birds. In migration biology, these programs are best known in songbirds. The majority of songbirds rely on a genetic program inherited from their parents that will guide them during their first solo-migration. The phenotypic components of the program are crucial for thei
Poor public perception can obstruct a construction project in a damaging way. Knowledge about public opinion should be considered as a relevant area of expertise for project managers and as an essential cost element in the planning and completion of construction projects. A consensual approach to a siting controversy requires informal face-to-face interaction among chosen representatives from all
This study describes the chydorid (Branchiopoda, Anomopoda) assemblages from 66 European shallow lakes, and presents data relating the assemblages to lake type and ecological quality. Forty species, out of a total recorded European fauna of 60 species, were found in the study sites. No significant differences were found between chydorid assemblages associated with rock and plant substrata. Pattern
