Growth or reproduction? Resource allocation by female frogs Rana temporaria

The decision how to allocate marginal resources to reproduction and growth can have important effects on associated life-history parameters as well as on population dynamics. In addition to showing variation among individuals in a population, such allocation rules may be either condition-dependent or fixed in different individuals. While many studies on anuran amphibians have focused on egg number

Mao Zedong on Education

This is an annotated translation, with an introduction, of Mao Zedong's instructions on current educational work at an informal discussion with the heads of Education Departments from seven Chinese provinces and municipalities on 7 March 1957

Ett ögonblick i förhistorien – reflektioner kring en koncentration av ben från Uppåkra.

Under grävningssäsongen 2003 anträffades en ansamling med ben (U60527)(Fig. 1) strax norr om det numera berömda kulthuset i Uppåkra (fig. 2). Fyndet gjordes inom området för en offertradition från järnåldern där man hittat större mängder rituellt förstörda lans- och spjutspetsar liksom andra vapendetaljer spridda över en omkring 70 m2 stor yta (Helgesson 2004:224ff). Benansamlingen som bestod av o

Leachability testing of metallic wastes

The performance of two tests, a batch test and a percolation test for the characterization of waste as suggested in the EU council decision 2003/33/EC was investigated. The tests were carried out on two solid waste streams from a metal recycling industry. The concentrations of heavy metals Such as Cu, Zn and Pb were more than one order of magnitude lower than the proposed limit values. Generally,

Development of a four-element conical electron lens dedicated to high resolution Auger electron-ion(s) coincidence experiments

A four-element conical electron lens has been developed in view of its integration to a double toroidal electron energy analyzer (DTA) dedicated to Auger electron-ion coincidence measurements. The lens design, using electron trajectory numerical simulations, was entirely guided by the perspective of analyzing energetic electrons with high resolution in the multicoincidence regime. The design, cons

Thermal history of the Phanerozoic sedimentary succession of Skåne, southern Sweden, and implications for applied geology

Popular Abstract in Swedish Sedimentära bergarter såsom t.ex. sandstenar och lerskiffrar, bildas genom att lösa sediment (t.ex. sand och lera) ”bakas” hårda när de sjunker ned i jordskorpan. Anledningen till att många lagerföljder rör sig nedåt i jordskorpan beror till viss del på de ovanliggande sedimentens tyngd, men är i huvudsak ett resultat av de platt-tektoniska rörelser som hela tiden påverPost-depositional thermal conditions have been investigated throughout the Phanerozoic sedimentary succession in Skåne. Clay mineralogy and illite crystallinity have been the main tools for the Lower Palaeozoic strata. Within the Mesozoic sequence thermal influence was examined using RockEval pyrolysis and vitrinite reflectance analysis. Clay mineralogy of the Lower Palaeozoic shales and mudstone

Preoperative diagnosis of ovarian tumors using Bayesian kernel-based methods

Objectives To develop flexible classifiers that predict malignancy in adnexal masses using a large database from nine centers. Methods The database consisted of 1066 patients with at least one persistent adnexal mass for which a large amount of clinical and ultrasound data were recorded. The outcome of interest was the histological classification of the adnexal mass as benign or malignant. The out

Antibiotics differ in their tendency to cause infusion phlebitis: a prospective observational study.

Intravenous administration of antibiotics is a known risk factor for infusion phlebitis. We have previously demonstrated differences in cell toxicity for 4 antibiotics. Clinical experience indicates that antibiotics differ in their tendency to cause phlebitis. The present study was done prospectively on 550 patients with 1386 peripheral venous catheters. The incidence of phlebitis was 18.5% with a

Lewis phenotype of erythrocytes and Leb-active glycolipid in serum of pregnant women

In an attempt to provide an explanation for the previously reported effect of pregnancy on the Lewis phenotype of erythrocytes, the level of Leb-active glycolipid in serum was compared with the reactions of erythrocytes, using samples obtained from 73 nonpregnant women, 74 women at the time of delivery, and 2 women at weekly intervals during their pregnancy. In this Swedish population, the frequen

Texter i dialog. En studie i gymnasieelevers litteraturläsning

The thesis is a reception study and the focus of the research is on what happens during the reading process when an upper secondary school class reads fiction. The theoretical basis consists of theories of reading as transaction and the envisionment-building and dialogic classroom. A process-based and relational perspective on reading, writing and oral exchange in teaching has been central. The e

God in the Fourth Gospel : A Hermeneutical Investigation of the History of Interpretations

Popular Abstract in Swedish Bibeln, och framför allt Nya Testamentet, har präglat det västerländska tänkandet i en utsträckning som inte alltid noteras i nyare historieskrivning. En ledande roll har spelats av de uppfattningar av Gud som förmedlas av de fyra evangelierna. Inte minst har läsningar av Johannesevangeliet genomsyrat de kristna tänkarnas försök att formulera synen på Guds väsen, egenskThis book presents an exhaustive and systematic investigation of six representatives of three important periods of New Testament interpretation: Martin Luther, John Calvin, Brooke Foss Westcott, Heinrich Julius Holtzmann, Rudolf Bultmann and Raymond E. Brown. They serve as dialogue partners in an investigation of the notion of God in the Fourth Gospel, a topic that has been called “the neglected f

Carbon allocation in mycelia of arbuscular mycorrhizal fungi during colonisation of plant seedlings

The direction of carbon (C) allocation in mycorrhizal mycelia is of fundamental importance to coexistence of individual plants. We therefore investigated the transfer of C from established plants to plant seedlings through fungal mycelia. C allocation by the arbuscular mycorrhizal (AM) fungus Glomus intraradices, from 'donor' plants to mycelia in soil and two different species of introduced 'recei
