This paper reports a numerical investigation on the effect of cavity geometry on fuel transport and mixing processes in a scramjet combustor with a single rear-wall-expansion cavity. The numerical solver and the LES methods were validated against available experimental data and the numerical results were shown in good agreement with the experiments. Effect of the cavity rear wall height on the non
Den reformation som inleddes för 500 år sedan kom att innebära betydande förändringar av gudstjänstfirandet i Sverige. I årets volym av Svenskt Gudstjänstliv utforskar vi motiven, förloppen och konsekvenserna.Gudstjänstreformernas motiv behandlas av Ragnar Holte och Thomas Girmalm. Holte tecknar den allmänna bakgrunden i en artikel om Luther och Melanchthon och deras mest kända skrifter. Thomas Gi
In various environments new agents may base their decisions on observations of actions taken by a few other agents in the past. In this paper we analyze a broad class of such social learning processes, and study under what circumstances the initial behavior of the population has a lasting effect. Our results show that this question strongly depends on the expected number of actions observed by new
Background: Late health consequences of treatment for childhood leukemia are well documented. Although individuals with Down syndrome (DS) have a substantially increased risk of leukemia, information on late effects in this group is almost nonexistent. The aim of this study was to evaluate the mortality and morbidity among 5-year leukemia survivors with DS. Procedure: We compared 5-year leukemia s
Trots allt prat om sekularisering är predikan ännu den i särklass vanligaste formen av offentligt tal i vårt land. Predikanter träder bokstavligen upp ”i tid och otid” (2 Tim. 4:2), liksom de har gjort genom hela kyrkans historia. De sex artiklarna i denna årsbok handlar om predikan både historiskt (”i tid”) och principiellt (”i otid”).Katarina Hallqvist och Erik Claeson har hämtat upp texter ur d
The first Cistercian monastery in medieval Sweden was Alvastra, founded in 1143. Its library is almost completely lost, only three manuscripts remain. One of these, ms. C 37 in Uppsala University Library, contains a collection of 32 complete and three incomplete sermons.The writing in the sermon collection belongs to the first half of the thirteenth century. No direct source has been found. It is
This chapter provides an overview of antisemitism in modern Russia, not necessarily chronological, but a short survey of the different ways by which antisemitism appeared over the course of the twentieth century. Zvi Gitelman has famously characterized twentieth-century Jewish-Russian relations as a “century of ambivalence” during which periods of friendly co-existence were disrupted by violent co
The invention of computers revolutionized the way of doing science and in particular the field of mathematics. Computers were faster than any human mind in doing calculations and they did not make mistakes opening a wide range of possibilities that earlier where in practice uncomputable. Scientists observe the behavior of nature and find mathematical equations that model the different phenomena. IThe efficient simulation of thermal interaction between fluids and structures is crucial in the design of many industrial products, e.g. turbine blades or rocket nozzles. The main goal of this work is to present a high order time adaptive multirate parallel partitioned coupled method for the efficient numerical solution of two parabolic problems with strong jumps in the material coefficients that
Chronic inflammation may be involved in cancer development and progression. Using 28 inflammatory-related proteins collected from prospective blood samples from two case-control studies nested in the Italian component of the European Prospective Investigation into Cancer and nutrition (n = 261) and in the Northern Sweden Health and Disease Study (n = 402), we tested the hypothesis that an inflamma
We analyze how much a core rational-choice model can explain the temporal and spatial variation in fertility and school enrollment in France during the 19th century. The originality of our approach is in our reliance on the structural estimation of a system of first-order conditions to identify the deep parameters. Another new dimension is our use of gendered education data, allowing us to have a
Recension av Bernt Hermele, ”Kommer de, så skjuter jag oss” : Om svenska judars liv i skuggan av förintelsen.
The nervous system is engaged by infection, indirectly through inflammatory cascades or directly, by bacterial attack on nerve cells. Here we identify a neuro-epithelial activation loop that participates in the control of mucosal inflammation and pain in acute cystitis. We show that infection activates Neurokinin-1 receptor (NK1R) and Substance P (SP) expression in nerve cells and bladder epitheli
There is growing evidence that a significant share of global food is thrown away, with concomitant detrimental repercussions for sustainability. Reducing food waste is a key sustainability challenge for the food service industry. Despite the significance of this issue to the global foodservice industry, the link between innovation practices and food waste management has received limited attention
This paper examines the linkages between cash-crop income and other dimensions of poverty to interrogate assumptions regarding the relationship between agricultural income and poverty alleviation. The analysis treats poverty as a multi-dimensional and socially disaggregated phenomenon. The paper employs a mixed methods approach to case studies of Ghana and Ethiopia to explore two critical issues.
The Faroe Islands hold a key position in the North Atlantic region for tephra studies due to their relative proximity to Iceland. Several tephras have been described over the last 50 years in peat and lake sediment sequences, including the type sites for the Saksunarvatn and Mjáuvøtn tephras. Here we present a comprehensive overview of Holocene tephras found on the Faroe Island. In total 23 tephra
