Terpene emissions from the top-canopy layer (at 20 m) of one 118-year-old Norway spruce tree were measured between June and September 2013 using a branch chamber. Total terpene emissions varied from 0.05 to 332.5 μg gdw -1 h-1 with a peak in August. Monoterpenes dominated throughout the summer and on average accounted for 65% of the total terpene mass, followed by sesquiterpenes (29%) and isoprene
There are few better examples of analysis - the critical thinking skill of understanding how an argument is built - than Robert Dahl's Democracy and its Critics. In this work, the American political theorist closely analyzes the democratic political system and then evaluates whether the arguments that are in favor of it are, in fact, rigorous. Dahl sets out to describe democracy's merits and probl
Even when the editor of the popular journal Populär Arkeologi claims to be communicating the latest advances in archaeological research to the public and that the authors often are professional archaeologists, this is done very rarely and focuses mostly on dating and artifacts. Is it the editor’s responsibility or must the archaeologists themselves highlight these issues in their articles? Common
The evaluation of satellite precipitation products (SPPs) at regional and local scales is essential in improving satellite-based algorithms and sensors, as well as in providing valuable guidance when choosing alternative precipitation data for the local community. The Tropical Rainfall Measuring Mission (TRMM) has made significant contributions to the development of various SPPs since its launch i
Earlier studies have implied a change in dietary habits of the Swedish population towards a low carbohydrate, high fat diet. Questions have been raised about the development in recent years and potential health effects. We have investigated the dietary intake of Swedish female students enrolled in a university nutrition course between 2002 and 2017. The students carried out self-reporting of all f
The last decade has revealed hundreds of genetic variants associated with type 2 diabetes, many especially with insulin secretion. However, the evidence for their single or combined effect on beta-cell function relies mostly on genetic association of the variants or genetic risk scores with simple traits, and few have been functionally fully characterized even in cell or animal models. Translating
A reduced kinetic mechanism for methanol combustion at spark-ignition (SI) engine conditions is presented. The mechanism consists of 18 species and 55 irreversible reactions, small enough to be suitable for large eddy simulations (LES). The mechanism was reduced and optimized using the comprehensive mechanism (AramcoMech 2.0) as a starting point, to maintain performance at stoichiometric condition
Ciliary neurotrophic factor (CNTF) promotes photoreceptor survival but also suppresses electroretinogram (ERG) responses. This has caused concerns about whether CNTF is detrimental to the function of photoreceptors because it is considered to be a potential treatment for retinal degenerative disorders. Here we report that the suppression of ERG responses is attributable to negative regulation of t
We studied the effects of high-dose methylprednisolone on the survival of intrastriatal neural xenografts and the host responses against them. Dissociated mesencephalic tissue from inbred mouse (CBA-strain) embryos was transplanted to the intact striatum of adult Sprague-Dawley rats. The rats received either daily injections of methylprednisolone (30 mg/kg), or cyclosporin A (10 mg/kg), or no immu
Gangliosides play important biological roles and structural characterization of both the carbohydrate and the lipid moieties is important. The FT-ICR MS/MS techniques of electron capture dissociation (ECD), electron detachment dissociation (EDD), and infrared multiphoton dissociation (IRMPD) provide extensive fragmentation of the protonated and deprotonated GM1 ganglioside. ECD provides extensive
I have a returning nightmare: my computer breaks down and I am losing all my written words. Losing the record I keep of my stories. The trails of where I have been in my thoughts dissolve and I am left empty. ”Stories matter. Many stories matter”, writer Chimamanda Ngozi Adichie reminds us in her famous TED-talk on ’the danger of a single story’ (Adichie 2009). Telling stories from my research on
Background: Current equations for estimated glomerular filtration rate (eGFR) that use serum creatinine or cystatin C incorporate age, sex, and race to estimate measured GFR. However, race in eGFR equations is a social and not a biologic construct.Methods: We developed new eGFR equations without race using data from two development data sets: 10 studies (8254 participants, 31.5% Black) for serum c
Low-molecular-weight (MW) polyols are organic osmolytes influencing water activity. We have investigated the effects of polyol molecules (glycerol and sorbitol) on the optical and triplet excitation dynamics of light-harvesting complex 2 (LH2) from Rhodobacter (Rba.) sphaeroides in buffer-detergent solutions. The resonance Raman spectroscopy demonstrated that, on increasing glycerol and sorbitol v
This article aims to describe key challenges of preparing and releasing audio material for spoken data and to propose solutions to these challenges. We draw on our experience of compiling the new London-Lund Corpus 2 (LLC-2), where transcripts are released together with the audio files. However, making the audio material publicly available required careful consideration of how to, most effectivel
This article presents baseline isotope values for plant and animal samples collected from across southern California. A total of 80 samples representing 50 species were collected and analyzed for this project. This original dataset includes 31 plant species, 13 finfish species, 3 mollusk species, 2 crustacean species, and 1 echinoderm. Plant samples were collected by the authors and an undergradua
The composition of enclosure materials used in many TV sets sold on the European market has changed significantly since the early 1990s. To determine the potential impact of this change on TV fire safety, a review of European and US TV set fire statistics has been carried out. TV set fires can have internal electrical causes due to faults not apparent at the time of manufacture, simple wear and te
Den aisopiska fabeln etablerades som genre i den grekiska antiken och nådde Skandinavien under medeltiden. I svensk kultur upplevde fabeln en storhetstid under den tidigmoderna epoken (1500–1800). Monografin Fabelbruk i svensk tidigmodernitet. En genrehistorisk studie tar ett helhetsgrepp om fabelgenrens historia i Sverige under denna 300-årsperiod. I dialog med ny internationell fabel- och genrefEstablished as a genre in Greek antiquity, the Aesopic fable reached Scandinavia during the Middle Ages. In Sweden, the fable experienced its glory days during the early modern epoch (1500–1800). The monograph Fabelbruk i svensk tidigmodernitet. En genrehistorisk studie [Usage of Fable in Swedish Early Modernity. A Genre History] takes a comprehensive look at the history of fable in Sweden during
