Context. To use the data in the future Gaia catalogue it is important to have accurate estimates of the statistical uncertainties and correlations of the errors in the astrometric data given in the catalogue. Aims. In a previous paper we derived a mathematical model for computing the covariances of the astrometric data based on series expansions and a simplified attitude description. The aim of th

The purpose of this essay is to use feminist institutional theory to examine how the social construction of military gender roles is expressed in a military institution. My object of study is the Israeli military given their compulsory military service that intends to include both men and women. The theoretical framework this essay intends to examine are based on previous research from feminist th

Vitamin D supplements have been used to prevent fractures. The effect may be mediated through increased bone mass, but also through reduced falling propensity. The aim of this study was to evaluate the association between 25-hydroxy vitamin D levels (25OHD), fall-associated variables (including tests of functional performance), and fracture in ambulatory women. At baseline 25OHD was measured in 98

A multicenter, open-label, randomized efficacy and safety study was performed with combined human chorionic gonadotropin (hCG) and recombinant follicle-stimulating hormone (recFSH) (Puregon(R)) treatment to induce spermatogenesis in hypogonadotropic hypogonadal male patients. Patients were pretreated for 16 weeks with hCG to normalize testosterone levels. A total of 30 of 49 (61%) subjects had nor

Background and Purpose - The causes of death of patients with cerebral venous thrombosis (CVT) have not been systematically addressed in previous studies. We aimed to analyze the causes and predictors of death during the acute phase of CVT in the International Study on Cerebral Vein and Dural Sinus Thrombosis (ISCVT) to identify preventable or treatable causes. Methods - ISCVT is a multinational,

A full century ago, H. G. Wells said that a hand seemed to have descended from the sky and turned man’s face towards the future. Wells wrote in an era which saw a new world appear through the progress of technology. Today we may be just as attracted to new technology, but that great hand seems to have come down again and turned man’s head back towards the past. Our own time is characterized by an

A succession of 26 conodont zones and 63 successive subzones and conodont faunas have been identified in the exposed latest Landovery to latest Ludlow strata of Gotland, Sweden. All zones, and several of the subzones and faunas, have been identified elsewhere on Baltica as well as on other palaeocontinents, indicating that this zonation serves well as the standard zonation for calcareous successio

Summary This report presents results from the project ”Converting direct resistive electric heating into district heating - customer related aspects” conducted at the division of Efficient Energy Systems, Department of Energy Sciences, Lund University. The main objective of this study was to investigate how specific households within one housing area (Sandsbro in Växjö with 110 one-family houses)

The aim of the present study was to investigate the kind of support society offer parents, by illuminating some of the parent education programs which are arranged by social services. By interviewing some of those who are involved in these education programs, we tried to figure out what society would like to mediate as good parenting. Our main questions was: * Why are parental education needed i

Background: Adjuvant chemotherapy (ACT) for breast cancer improves relapse-free survival (BCRFS) and overall survival. Differences in terms of efficacy and toxicity could partly be explained by the significant interpatient variability in pharmacokinetics which cannot be captured by dosing according to body surface area. Consequently, tailored dosing was prospectively evaluated in the PANTHER trial

Macroeconomic crises are common as well as economically, socially and politically costly. Fiscal policy plays an important role in alleviating the costs of the crisis. However, recent experiences suggest that the public finances often are unprepared for a crisis. Deficits and debt levels prior to the crisis are commonly too high, limiting the government’s ability to respond to the crisis. In thi

Popular Abstract in Swedish För att minska CO2-utsläppen från godstransporter har politiker i Europa under de senaste tio åren framhävt att det krävs ett skifte i transportslag för europeiska transporter, från flyg- och lastbilstransporter till mer miljövänliga tåg- och sjötransporter. Intermodala väg-järnvägstransporter, där en kombination av tåg och lastbil använts för att förflytta lösa standarAmong policy-makers in Europe the modal shift - a shift från polluting modes of freight transport to less polluting modes - has been a popular suggestion for reducing CO2-emissions of transportation. In particular, intermodal road-rail solutions, where a combination of road and rail transport is utilized to move trailers and containers, have been stressed as an important measure to reach de desire

A previous study compared two student groups that played a mathematics game based on a teachable agent. One group played with, and the other without, the inclusion of a social conversation module: a chat between the student and the teachable agent. Results were that students who used the game with the chat included had a more positive experience of the game and learned more in the sense of teachin

OBJECTIVE: To evaluate the early and intermediate outcome of a consecutive series of emergency endovascular aneurysm repairs (eEVAR) of computed tomography (CT)-verified infrarenal ruptured abdominal aortic aneurysm (rAAA) at a single tertiary referral centre. METHODS: Prospectively collected data of patients operated between April 2000 and October 2007 were retrospectively reviewed and all their

Lately, the idea of ‘non-toxic’ (or ‘clean’) material cycles has become increasingly popular as a starting point for the consideration of circular economy strategies among leading regulating actors, such as the European Commission (2017). However, it should be apparent that, by default, circular economy aspirations awaken a potential policy conflict between increased circulation of resources and r

BACKGROUND: For 40 years cricoid pressure has been used to prevent regurgitation of gastric contents during induction of anaesthesia. Recent studies have emphasised use of more moderate force so as not to deteriorate ventilation or endotracheal intubation. This study was undertaken to assess the current practice and knowledge of cricoid pressure among anaesthesia personnel in southern Sweden. METH

BACKGROUND Anti-Müllerian hormone (AMH) is a promising marker of ovarian reserve. The aim of the study is to assess the circadian variation in AMH, and to evaluate its clinical relevance and biological aspects as an effect of age and other endocrine mechanisms involved in the regulation of AMH secretion. METHODS Nineteen healthy non-smoking, regularly menstruating female volunteers with body mass

Popular Abstract in Swedish Senpleistocen nedisningshistoria på Nordöstgrönland: kosmogen exponeringsdatering, isutbredning och isdynamik Under den senaste istiden var periodvis stora delar av landmassorna på norra halvklotet istäckta. Idag är den Grönländska inlandsisen den enda större återstoden av detta, men likväl binder den tillsammans med isen i Antarktis och jordens mindre glaciärer väldigtThe aim of this thesis was to use cosmogenic exposure dating to investigating whether highly weathered landscapes in the Northeast Greenland fjord zone have developed during prolonged ice free conditions or have been preserved beneath cold-based ice. Previous work along the Northeast Greenland coast has presented two conflicting hypotheses for the extent of the Greenland Ice Sheet during the last
