Gas turbine systems are predominantly designed to be fuelled with gaseous fuels within a limited Wobbe index range (typically HHV=45-55 MJ/Nm3 or 1200-1480 Btu/scf). When low calorific fuel gases are fired, the engine will be forced to operate outside its design envelope. The added mass flow will typically raise the cycle pressure ratio and in two-shaft designs also raise the gas generator shaft s
We present a simple and rapid microfluidic device capable of extracting and concentrating the parasite causing the fatal disease sleeping sickness (SS) from blood. The device is based on deterministic lateral displacement (DLD) and constructed with a single inlet with flow induced by an ordinary syringe. The simplicity is crucial as the device is intended for use in the resource depraved areas whe
This contribution deals with investigations on enhanced Fischer–Burmeister nonlinear complementarity problem (NCP) functions applied to a rate-dependent laminate-based material model for ferroelectrics. The framework is based on the modelling and parametrisation of the material’s microstructure via laminates together with the respective volume fractions. These volume fractions are treated as inter
It is a human fundamental to desire to be valued, loved and respected - to be significant. Social exclusion induce significance loss which elicits a 'quest for significance' - the search for opportunities to re-gain significance. The present article establishes this relation in a laboratory experiment (N = 71, mean age = 28, SD = 10.42, 65% women, 35% men), showing that socially excluded individua
Phase shifter-based hybrid beamforming has received a lot of attention at millimeter-wave frequencies for cellular communications. Nevertheless, the implementation complexity of such beamformers is rather high due to the complexities involved in designing and fabricating the required radio-frequency (RF) circuits. In contrast, lens-based RF beamformers significantly reduce the implementation compl
The photoreceptors and eyes of four fish species commonly cohabiting Fennoscandian lakes with different light transmission properties were compared: pikeperch Sander lucioperca, pike Esox lucius, perch Perca fluviatilis and roach Rutilus rutilus. Each species was represented by individuals from a clear (greenish) and a humic (dark brown) lake in southern Finland: Lake Vesijärvi (LV; peak transmiss
Research on air travellers’ willingness to pay (WTP) for climate change mitigation has focussed on voluntary emissions offsetting so far. This approach overlooks policy relevant knowledge as it does not consider that people may value public goods higher if they are certain that others also contribute. To account for potential differences, this study investigates Swedish adults’ WTP for a mandatory
The TRE3 research project focuses on the development of a new and innovative timber frame wall modulus for emergency housing facilities. The wall modulus, in this paper referred to as Hybrid Timber Frame (HTF) wall system, is an evolution of the traditional Light-Frame Timber (LFT) structural systems and combines the advantages and some peculiar aspects of lightweight structures to the potentialit
Recently, we identified unique processing patterns of apolipoprotein A2 (ApoA2) in patients with pancreatic cancer. Our study provides a first prospective evaluation of an ApoA2 isoform (“ApoA2-ATQ/AT”), alone and in combination with carbohydrate antigen 19–9 (CA19-9), as an early detection biomarker for pancreatic cancer. We performed ELISA measurements of CA19-9 and ApoA2-ATQ/AT in 156 patients
Nano-magnetic biocatalyst particles, lipase-immobilized chitosan-crosslinked magnetic nanoparticles (LCMNs) were prepared by a new approach integrated from magnetic nanoparticle preparation, in situ thin layer coating and crosslinking of chitosan, and enzyme immobilization method. Thin layer coating of magnetic (Fe3O4) by crosslinked chitosan nanoparticles were prepared by reacting FeCl3.6H2O and
Mountain areas often hold special species communities, and they are high on the list of conservation concern. Global warming and changes in human land use, such as grazing pressure and afforestation, have been suggested to be major threats for biodiversity in the mountain areas, affecting species abundance and causing distribution shifts towards mountaintops. Population shifts towards poles and mo
The effects of socio-economic/occupational factors on gastric cancer at various subsites (including corpus, cardia and unspecified cancers) are not well known. To investigate this issue, we carried out a follow-up study on the economically active Swedish population, based on the Swedish Family-Cancer Database. We calculated standardized incidence ratios and 95% confidence intervals for different o
Objective: The objective of this study was to examine the associations between socioeconomic/occupational factors and pancreatic cancer. Methods: The Swedish Family-Cancer Database was used to calculate standardized incidence ratios for different social classes and occupational groups. Lung cancer risks were also determined. The reference group was all the economically active population. Results:
The reasons for the high risk of contralateral breast cancer are not understood, although polygenic mechanisms have been suggested to be involved. The nationwide Swedish Family-Cancer Database was used to examine the interaction of the risks for contralateral and familial cancer. Relative risks were separately determined for contralateral and familial breast cancers, and these were tested for addi
OBJECTIVES: The aim of this study is to investigate associations between hospitalization for epilepsy and two factors: socioeconomic status and occupation.DESIGN AND SETTING: A nationwide database was constructed in Sweden by linking the Swedish Census to the Hospital Discharge Register to obtain data on all first-time hospitalizations for epilepsy in adults in Sweden during the study period (1987
Background: Animal models of human diseases are often used in biomedical research in place of human subjects. However, results obtained by animal models may fail to hold true for humans. One way of addressing this problem is to make animal models more similar to humans by placing human tissue into animal models, rendering them chimeric. Since technical and ethical limitations make neurological dis
In this work a simplified approach to array optimization for the DC resistivity and induced polarization method have been created and tested. The optimization method uses the centre of the sensitivity function for the individual electrode configurations, called the mass centre, which is spread over the area of investigation, wherefrom the name Spread of Mass Centre (SMC). This array has been teste
BACKGROUND: Traumatic acute subdural hematomas (ASDHs) are associated with high rate of morbidity and mortality, especially in elderly individuals. However, recent reports indicate that the morbidity and mortality rates might have improved.OBJECTIVE: To evaluate postoperative (30-d) mortality in younger vs elderly (≥70 yr) patients with ASDH. Comparing younger and elderly patients, the secondary o
We examine how building and appliance technologies relate to their use by occupants through practices at home and at work. The aim is to analyse how practices are influenced by buildings and other technologies and by social requirements and to add to ongoing research on how to contribute to a transition to more sustainable everyday practices. Interview, quantitative and observational material are
