Recent theoretical developments of growth models, especially on unified theories of growth, suggest that the child quantity-quality trade-off has been a central element of the transition from Malthusian stagnation to sustained growth. Using an original censusbased dataset, this paper explores the role of gender on the trade-off between education and fertility across 86 French counties during the n

Med anledning av att VA-verket i Malmö planerade att lägga om och förnya vatten-ledningsnätet i Östergatan och S:t Gertrudsgatan genomfördes en förundersökning i form av schaktningsövervakning. Övervakningen utfördes av personal från Malmö Kulturmiljö. Exploateringsområdet berörde Malmö äldre stadsområde (RAÄ 20). Östergatan var under medeltiden en del av stadens huvudstråk och benämndes tidigt s

Discussion of the terms "intertext" and "intertextuality" with primary focus on film studies.

We reportwhat is to our knowledge the first production of gain by inner-shell photoionization of ions. Photoionization of 4d electrons from In$+$ ions created a population inversion on a 185-nm In2$+$ transition. This scheme is an isoelectronic scaling of the 442-nm Cd$+$ laser. A single-pass gain constant of 0.9 {\textpm} 0.3 cm{\textminus}1 over a 0.4-cm path was pumped by soft x rays generated

Popular Abstract in Swedish Avhandlingen behandlar problem inom den tillämpade matematiken med speciell inriktning mot elektromagnetisk vågutbredning. Exempel på studerade elektromagnetiska vågor är radiovågor, mikrovågor och ljus. Det speciella som skiljer den här studien från andra liknande studier, är att det medium som vågen passerar genom är ickestationärt, vilket innebär att det ändras underPropagation of transient waves in nonstationary, inhomogeneous, dispersive, stratified media is considered. Waves originating from sources exterior to the scatterer as well as from internal sources are treated. Algorithms are developed and illustrated by computations of wave phenomena in stationary, nonstationary and weakly nonlinear media. In the theoretical part, the underlying hyperbolic equati

In this chapter a thorough review of the latest research findings on power generation from non-conventional low heat sources is presented. Main discoveries and results of research works ranging from source exploitation technologies to final power production are reported and discussed to offer an overview of their potential. Firstly the concept of low-grade source is presented and the main energy s

Surface temperature in internal combustion engines is of high interest when studying heat losses. Two approaches for retrieving the surface temperatures are thermocouples and Laser Induced Phosphorescence, LIP. This study aims to analyze LIP as a technique for measuring surface temperature in internal combustion engines. The motivation for this study is the need for accurate surface temperatures w

The embryo has traditionally been considered to completely rely upon parental strategies to prevent threats to survival posed by predators and pathogens, such as fungi. However, recent evidence suggests that embryos may have hitherto neglected abilities to counter pathogens. Using artificial fertilization, we show that among-family variation in the number of Saprolegnia-infected eggs and embryos i

1700-talets föreställningar om natur och naturlighet hade stor inverkan på estetikens och det estetiska omdömets utveckling under seklet. "Naturlighet" inom estetiken kan betraktas som en "passepartout-term" som där en rad delvis motsägelsefulla attribut kan förenas.

We show that the all-spectrum transmission blockage through a low-pass screen is bounded by the static polarizability per unit area of the screen, irrespective of how complicated the materials involved are. The angular dependence at oblique incidence is investigated, and the results are verified by measurements on an array of split ring resonators.
