The functional role of herbivores in tropical rainforests remains poorly understood. We quantified the magnitude of, and underlying controls on, carbon, nitrogen and phosphorus cycled by invertebrate herbivory along a 2800m elevational gradient in the tropical Andes spanning 12 degrees C mean annual temperature. We find, firstly, that leaf area loss is greater at warmer sites with lower foliar pho
The aim of this article is to give a tentative illustration of how a creative, postpolitical citizen is imagined and encouraged to unfold within the frame of a city renewal project. As a starting point, the article outlines an exploratory framework structured through the analytical concept of postpolis. Postpolis is a term that offers an illustration of the distinguishing qualities of contemporary
General hospital care and treatment of mentally ill patients in a Swedish town was studied in records for 503 patients, 1896–1905. Restraint was extremely rare; 65% left the hospital as healthy or improved. Non-psychotic and alcoholic patients spent fewer days in hospital than patients with psychosis or dementia. There was no evidence of a social status bias. For 36% of the patients a certificate
A three stacked power amplifier implemented in 28nm fully depleted silicon-on-insulator complementary metal oxide semi-conductor technology (FDSOI CMOS) is presented. It has a differential architecture with on-chip input and output transformer baluns. The PA achieves a saturated output power level of 17.9dBm with a peak power added efficiency of 7% and an output referred gain compression point of
IMPORTANCE Delayed umbilical cord clamping has been shown to improve iron stores in infants to 6 months of age. However, delayed cord clamping has not been shown to prevent iron deficiency or anemia after 6 months of age. OBJECTIVE To investigate the effects of delayed umbilical cord clamping, compared with early clamping, on hemoglobin and ferritin levels at 8 and 12 months of age in infants at h
Background. Knowledge of sensitization and elicitation thresholds and the time-dose relationship for elicitation of contact dermatitis is important in order to provide safe products for consumers. Objective. Since previous studies performed with eugenol had showed negative results in a repeat open application study (ROAT) study, we wanted to perform a ROAT with higher concentration (maximum allowe
Increased production and consumption of local food may reduce the negative environmental, social, and economic impacts of industrialized and globalized food production. Here we examined potential barriers to increasing production and consumption of food produced in Iceland. First, we developed a new framework to address the behaviors of production and consumption simultaneously, to comprehensively
Chromosome analysis of lymphoma cells was performed in 54 untreated patients with non‐Hodgkin's lymphoma (NHL). 10 patients had a history of daily occupational handling of organic solvents for at least 1 year (exposed group) and 44 patients had never (or only for shorter periods) worked with solvents (unexposed group). There were no differences between exposed and unexposed patients regarding age,
BACKGROUND: Studies have reported some evidence of adverse effects of organochlorine exposures on child development, but the results have been inconsistent, and few studies have evaluated associations with child behavior. OBJECTIVE: We investigated the association between prenatal and early-life exposures to 2,2′,4,4′,5,5′ -hexachlorobiphenyl (PCB-153) and 1,1-dichloro-2,2-bis(p-chlorophenyl)-ethy
Lipidic cubic phase systems (LCPs) are excellent carriers for immobilized enzymes due to their biocompatibility and well-defined nanoporous structure. Lipidic cubic phases act as a convenient matrix to incorporate enzymes and hold them in the vicinity of electrode surfaces in their fully active forms. Corynascus thermophilus cellobiose dehydrogenase (CtCDH) was trapped in a monoolein cubic phase,
Background Sarcopenia and poor physical function are common in patients with chronic kidney disease (CKD). Our aim was to investigate the relationships between muscle mass and measured glomerular filtration rate (GFR) and between muscle mass and strength and balance, respectively, in patients with CKD stages 3–5. Methods This is a baseline data analysis of a randomized controlled clinical trial.
Routine endomyocardial biopsy (EMB) to detect acute cellular rejection (ACR) late (>1 year) after heart transplantation (HT) remains debated. To gain knowledge on late ACR and thereby approach this issue, we studied the incidence, predictors, and outcome of late ACR. 815 late EMBs from 183 patients transplanted 1988-2010 were retrospectively reviewed until June 30, 2012. Only 4.4% of the routine a
Examination of ester-linked phospholipid fatty acids (PLFA) have provided a means to characterize the community structure of microbial assemblies. Attempts to analyze such acids at low picomolar levels in environmental samples by gas chromatography and chemical ionization mass spectrometry (CIMS) using positive or negative ion detection, showed that the limit of detection (LOD) was mainly dependen
The law that banned doping substances in Sweden was founded in 1991 and was strengthened in 1999 and 2011. The use of anabolic androgen steroids (AAS) however, is still increasing. Research about AAS is limited and the approximation of the number of AAS users is uncertain. On the gyms there are warnings about punishments risked if one is caught using AAS. But those warnings are without any informa
Popular science Using remote sensing to assess drought in Somalia Somalia, the country in East Africa in a region referred to as Horn of Africa is in a civil war, conflict and unrest since 1991. The prolonged conflict increases the impact of droughts in the country which is already prone to drought continuously. The country is frequently exposed to drought, occurring moderately every 3-4 years a
This thesis handles the problem with fluid selection in organic Rankine cycles application. The main goal was to write a program that based on user defined variables finds the maximum power output from a range of fluids. The program was programmed in Matlab and is coupled with REFPROP that return the fluids characteristics as enthalpy and entropy etc. The program is preloaded with the fluids foun
Environmental and urbanization challenges during the last few decades encouraged steady growth of mass timber construction where attention is drawn to cross laminated timber (CLT) as one of the most interesting products in terms of mechanical properties, versatility, efficient prefabrication and sustainability. Standardisation and codification regarding testing and design of CLT elements are hence
Individual plants can modify the microenvironment within their spatial neighborhood. However, the consequences of microenvironment modification for demography and species interactions remain unclear at the community scale. In a study of co-occurring alpine plants, we 1) determined the extent of species-specific microclimate modification by comparing temperature and soil moisture between vegetated
