Enligt författarnas mångåriga erfarenhet från kustprojekt runt om i Sverige föreligger ett stort behov av en förbättrad terminologi på svenska vad gäller ingenjörsmässiga frågeställningar och planering av kustområden.Föreliggande artikel presenterar således en engelsk-svensk ordlista, inklusive förklarande kommentarer, med syfte att klargöra en lång rad ord och uttryck. Denna finns också att tillg
Den kände astronomen Tycho Brahe initierade meteorologiska observationer på ön Ven som noterades i endagbok, nästan oavbrutet från oktober 1582 till april 1597. Fastän observationerna huvudsakligen är kvalitativapå grund av dåtida brist på instrument och metoder kan en stor mängd användbar information erhållas fråndagboken beträffande molntäcke, nederbörd, vindhastighet och riktning, temperaturför
Ystads kommun arbetar med en fördjupning av översiktsplanen för staden Ystad med omnejd. Ystads havsnära läge gör att klimatförändringen kommer att innebära stora utmaningar. Stigande havsnivåer väntas leda till ökade erosions- och översvämningsrisker i kustnära områden. Samtidigt är efterfrågan på havsnära boende stor och kommunen planerar att bygga ut staden mot havet.

OBJECTIVES: We used findings from the Global Burden of Disease Study 2013 to report the burden of musculoskeletal disorders in the Eastern Mediterranean Region (EMR).METHODS: The burden of musculoskeletal disorders was calculated for the EMR's 22 countries between 1990 and 2013. A systematic analysis was performed on mortality and morbidity data to estimate prevalence, death, years of live lost, y
The Bridge is a television drama that is suggestive of the significance of place in understanding international formats. The specificity of place is built into the storytelling, as the format is located in the geo-cultural politics of border territories in three versions of the drama series set between Sweden and Denmark, Britain and France, and USA and Mexico (Filmlance International and Shine Gr
The bromide anation of tr-PtCl4BrH2O− has been studied at 25 °C and the chloride anations of tr-PtCl4BrH2O− and PtBr5H2O− at 50 °C. These reactions proceed via halide assisted mechanisms, compatible with the experimental rate laws determined. The bromide anation of tr-PtBr4CIH2O− studied at 50 °C gives PtBr5Cl2− via a bromide assisted path and PtBr62− via an REOA-path.

Dilute solutions of the square-planar tetra-aqua complex pt(H2O)42+ have been prepared in a 1.00 M perchloric acid medium by addition of excess silver(I) perchlorate to potassium tetrachloroplatinate(II), equilibration at 70°C, filtration of the silver chloride precipitate, and subsequent separation of the excess silver from the solution by electrolysis.

The oxidative addition of iodine to Pt(CN)42− is first-order with respect to iodide, iodine and complex. The reverse reductive elimination of iodide from trans-Pt(CN)4I22- is first-order with respect to iodide and Pt(CN)4I22−. The kinetics for the reaction between bromide and trans-Pt(CN)4ClH2O2− involves a rate-determining reductive elimination of chloride, followed by a rapid oxidative addition The oxidative addition of iodine to Pt(CN)42− is first-order with respect to iodide, iodine and complex.

Chloride anations of PtCl5H2O−, trans-PtCl4(H2O)2 and trans-Pt(CN)4ClH2O− in the presence of PtCl42− have been studied at 50°C in 1.00M perchloric acid medium.

The Cambrian Alum Shale Formation in the Andrarum-3 core from Scania,southern Sweden, consists of black siliciclastic mudstone with minor carbonate intercalations. Four facies comprise three siliciclastic mudstones and one fine-grained carbonate. The facies reflect deposition along a transect from deep ramp to basin on a Cambrian shelf. The three mudstone facies contain abundant clay clasts and la
