This study investigates the establishment of alternative cell fates during embryoid body differentiation when ES cells diverge into two epithelia simulating the pre-gastrulation endoderm and ectoderm. We report that endoderm differentiation and endoderm-specitic gene expression, such as expression of laminin 1 subunits, is controlled by GATA6 induced by FGF. Subsequently, differentiation of the no
Atmospheric dispersion represents a relatively overlooked problem in connection with the ultimate quality of ELT images corrected by adaptive optics (AO). The aim of this paper is to evaluate the contribution from atmospheric dispersion to the background level of the point-spread function (PSF). Since proper suppression of this level is important for the prospects for direct exo-planet observation
Objective To evaluate the implementation of automated chest compression cardiopulmonary resuscitation (ACC-CPR) after out-of-hospital cardiac arrest (OHCA) in Sweden during the years 2011 through 2015. The association between ACC-CPR and 30-day survival was studied as a secondary objective. Methods The Swedish cardiopulmonary resuscitation registry is a prospectively recorded nationwide registry o
We present a significantly improved acoustophoresis method to separate bacteria from red and white blood cells. As much as 98% of the bacteria were recovered, while only 0.06 % of the red and white blood cells remained. This 1600-fold relative enrichment was achieved by adjusting the center medium density, tightly controlling the chip temperature and stabilizing the fluid flows. This is a crucial
Industrial relations in Sweden are part of the Nordic legal tradition. This is characterised by labour law which is largely semi-discretionary law and collective agreements are the most important instrument for regulation of the labour market; these agreements offer a high degree of coverage. Trade unions are well organised and play a central role in the labour law system. During the past 25 years
A comparative experimental investigation has been performed, comparing the emissions from a synthetic jet fuel and from Jet AI. In the investigation, the unburned hydrocarbons were analyzed chemically and the regulated emissions of NOX, CO and HC were measured. All combustion tests were performed under elevated pressures in a gas turbine combustor rig. A Swedish company, Oroboros AB, has developed
Deterministic lateral displacement (DLD) is a powerful bimodal separation scheme [1] based on fluid flow through regular obstacle arrays that in its basic embodiment sends suspended particles in two different directions as a function of size. We show that without the need to seal devices and without the need for fluidic connections or pumps, particle separation can be achieved by the passive flow
Self-adaptation provides a principled way to deal with change during operation. As more systems with strict goals require self-adaptation, the need for guarantees in self-adaptive systems is becoming a high-priority concern. Designing adaptive software using principles from control theory has been identified as one of the approaches to provide guarantees. However, current solutions can only handle
The members of the genus Caldicellulosiruptor have the potential for future integration into a biorefinery system due to their capacity to generate hydrogen close to the theoretical limit of 4 mol H2/mol hexose, use a wide range of sugars and can grow on numerous lignocellulose hydrolysates. However, members of this genus are unable to survive in high sugar concentrations, limiting their ability t
Checkpoints er fremtrædende og helt uomgængelige i nye syriske romaner skrevet i krigsårene. Checkpoint(s) (ḥājiz – pl. ḥawājiz) er en del af det nye litterære ordforråd efter 10 år med opstand og konflikt. Checkpointene er centrale elementer i de landskaber historierne udspiller sig i, de styrer den narrative struktur og tydeliggør væsentlige temaer i den tilværelse i krig, litteraturen fremstillCheckpoints are prominent and completely unavoidable in new Syrian novels depicting the war years. Checkpoint (s) (ḥājiz / ḥawājiz) are part of the new literary vocabulary after ten years of revolt and conflict. The checkpoints are central elements in the landscapes in which the stories take place, they guide the narrative structure, and accentuate essential themes in the life in war. Confrontatio
‘Flight shame’ describes an unease about the climate implications of air travel, and bears evidence of a change in social norms that have so far associated flying with social status. This paper discusses whether Fridays for Future demonstrations and ensuing flight shame have influenced social norms regarding the desirability of air travel, and whether this is measurable in a decline in air travel,
The project examines how grassroots organizations and networks providing urban critical services in informal settlements contribute to improve the quality of life of urban dwellers and to more inclusive forms of urban governance, constructing the city from below.The project is informed by the study of Kisumu’s informal settlements’ Resident Associations, the Water Delegated Management Model, and t
Progress in the power conversion efficiency of solar cells based on metal-halide perovskite semiconductors has been astonishing for the past years. During their development, transient effects have been observed that gave rise to an uncertainty associated with the determination of device performance from current density-voltage (J-V) measurements. This effect becomes visible in a dependence of the
This paper demonstrates a new acoustofluidic approach to enrich extremely dilute cell suspensions 1000 times and higher, at flow rates of ≥0.5 mL/min and higher, addressing some of the needs in rare cell processing and water quality monitoring.
Rapporten beskriver prototyper av kontinuerliga tvåfraktionsinsamlare för övervakning av partikulära luftföroreningar i arbetsmiljö som har konstruerats. En prototyp är personburen och ger möjligheter till insamling av två partikelstorleksfraktioner i 18 diskreta intervall. PIXE-metoden (analys med partikelinducerad röntgenstrålning) används för multielementanalys av de erhållna proven. Även med m
The liberalised electricity market in Sweden stresses the fact that the electricity companies must focus on customer satisfaction. Two major customer surveys concentrating on households’ requirements concerning the electricity bill have been carried out in spring 2002. The interest in energy management lies within the fact that the electricity bill can be used as a feedback instrument to influence
The objective of this study was to increase the knowledge of local stakeholders' acceptance of model-generated data when used as a communication tool in water quality management. The Ronnea catchment in the southwest of Sweden was chosen as the study area. The results indicate the model-generated data served as a uniting factor. Simultaneously, the stakeholders were concerned with presented data,
