Synchrotron radiation X-ray tomographic microscopy (SRXTM) was used to virtually dissect and peel the shields off of the microscopic, bivalved phosphatocopine crustaceans in the Cambrian ‘Orsten’ type of preservation of Sweden. Doing so opened up for an array of concealed internal structures to be observed in a fully enclosed specimen of Hesslandona ventrospinata and a semi-enclosed specimen of He
HR 8799 is a star accompanied by four massive planets on wide orbits. The observed planetary configuration has been shown to be unstable on a timescale much shorter than the estimated age of the system (~30 Myr) unless the planets are locked into mean motion resonances. This condition is characterised by small-amplitude libration of one or more resonant angles that stabilise the system by preventi
Coincident with increased utilization of the Icelandic highlands, its image as a unique and pristine wilderness is gradually changing. People’s perception of wilderness is influenced by a number of factors relating to their culture and socio-economic background. Furthermore, how people value pristine land or define wilderness varies depending on the location and function of the assessment. Therefo
This paper presents annual estimates of total and per-capita GDP at 1910 prices for the regions of Imperial Austria from the origin of the Dual Monarchy (1867) to the eve of WWI (1913). The time paths of regional GDP are estimated from the yield of the tax on the transfer of real and financial property which is itself very highly correlated with the Schulze (2007) estimates of regional GDP for cen
Despite having been subject to a strong and many-sided critique, instrumental rationality persists as paramount in transport planning practice and research. This paper argues that it is crucial to acknowledge the prescriptive and normative facet of instrumental rationality in order to understand its impact on transport planning. The aim is to explore to what extent pedestrian planning – within a s
OBJECTIVES: Prioritisation in healthcare is an issue of growing importance due to scarcity of resources. The aims of this study were firstly to describe decision makers' experience of prioritisation and their views concerning willingness to pay and how to finance healthcare costs. An additional aim was to compare the views of politicians and physicians. METHODS: The study was a cross-sectional stu
Evidence suggests the transcription factor GATA-2 is a critical regulator of murine hematopoietic stem cells. Here, we explore the relation between GATA-2 and cell proliferation and show that inducing GATA-2 increases quiescence (G(0) residency) of murine and human hematopoietic cells. In human cord blood, quiescent fractions (CD34(+)CD38(-)Hoechst(lo)Pyronin Y-lo) express more GATA-2 than cycling
Currently, most clinical range-modulated proton beams are assumed to have a fixed overall relative biological effectiveness (RBE) of 1.1. However, it is well known that the RBE increases with depth in the spread-out Bragg peak (SOBP) and becomes about 10% higher than mid-SOBP RBE at 2 mm from the distal edge (Paganetti 2003 Technol. Cancer Res. Treat. 2 413-26) and can reach values of 1.3-1.4 in v
A wall-slip model including limiting shear stress and the occurrence of slip at the interfaces between the lubricant and the adjacent surfaces is presented. The lubricant model is applied to EHL line contacts using smooth surfaces and isothermal conditions. The main part of the model concerns the lubricant velocities at the surfaces that are decoupled from the corresponding surface velocity giving
We study the reflection and transmission phase properties of two-terminal quantum structures coupled to a third lead. The systems are effectively three-terminal and current conservation is broken with regard to the original two-terminal systems. Two structures, a waveguide with an attached stub quantum dot and a waveguide with an inline, double-barrier confined quantum dot, are considered. The tra
One aim of rehabilitation after brain lesions should be to optimise the function of the remaining intact brain. Experimental studies on focal cerebral infarcts in the rat have demonstrated that postischemic environmental enrichment significantly improves functional outcome, increases dendrite branching and number of dendritic spines in the contralateral cortex, influences expression of many genes
In a prospective study of a consecutive breast cancer series accumulated in the period 1978-82, the S-phase fraction (SPF) and ploidy status were determined by flow cytometry performed on cell nuclei derived from samples of 580 primary tumors. Sixty percent of the tumors were non-diploid. After correction for debris the median SPF values were 7.3% overall, 12% for non-diploid tumors, and 2.9% for
Background: The maintenance of postural control is fundamental for different types of physical activity. This can be measured by having subjects stand on one leg on a force plate. Many studies assessing standing balance have previously been carried out in patients with ankle ligament injuries but not in patients with ankle fractures. The aim of this study was to evaluate whether patients operated
Uppsatsen syftar dels till att genom jämförelse mellan privat- och offentlig sektor klargöra kritikrättens gränser, det vill säga när en arbetstagares kritik mot arbetsgivaren övergår till illojalitet, dels till att klargöra hur gränsdragningen ser ut mellan att vara lojal respektive illojal. Vidare kommer uppsatsen att utreda under vilka omständigheter det föreligger sakliga skäl för uppsägning, The purpose of this thesis is to clarify the boundaries of the right to criticize an employer and to compare this right between the private and public sectors. It includes determining when an employee's criticism of their employer crosses into disloyalty. The thesis also aims to define the distinction between loyalty and disloyalty and to examine the circumstances under which valid grounds for
Bostadsmarknaden i Sverige är unik och skiljer sig från många andra länder. Sverige har en hyresreglering som håller hyror under marknadshyran vilket resulterar att hyresrätter inte fördelas enligt hyresgästers betalningsvilja. Detta leder till bostadskö som innebär långa köer i attraktiva områden och kortare till nästan ingen kö i andra. I en bostadskö fördelas hyresrätter enligt strikt kötid ochThe Swedish housing market is unique and differs from many other countries. Sweden has a rent regulation that keeps the rents below the market rent, which results in tenancies not being distributed according to the tenants’ willingness to pay. This leads to a housing queue which means long queues in attractive areas and shorter to almost no queue in others. In a housing queue, tenancies are distri
Sjukvårdspersonal riskerar att hamna i situationer där samtycke för ett medicinskt ingrepp inte kan inhämtas på grund av att patienten befinner sig i ett medvetslöst tillstånd. Vid givande av vård krävs som utgångspunkt alltid patientens samtycke, vilket är något som i praktiken inte alltid är möjligt. I akuta och allvarliga fall ingriper sjukvårdspersonal med stöd av 4 kap. 4 § PL när patientens Daily, medical personnel risk finding themselves in situations where consent for a medical procedure cannot be obtained due to the patient being in an unconscious state. According to Swedish law patient consent is always required before providing medical care, yet is something that is not always possible in practice. In acute and serious cases, medical personnel intervene under the support of Chap
How human beings perceive and interpret climate change and climate change policy is largely based on out narrative understanding of the political issue. Us as human beings create understanding of our social world through narrative practices. This essay takes its starting point in the new government formation in 2022 in the political context of Sweden. What narratives are present within the context
