Populärvetenskaplig sammanfattning: De senaste åren har försurningsforskningen varit intensiv, men intresset har främst varit inriktat på det atmosfäriska nedfallets miljöpåverkan. Dock påverkas markmiljön även av markanvändningsformen och dess intensitet. Inom skogsbruket har det sedan länge varit känt att gran påverkar markens pH-värde negativt jämfört med björk. Det är mera sparsamt med jämföraChemical and mineralogical studies of forest soils were made in four Norway Spruce (Picea abies (L.) Karst) and broadleaf stands in Asa in southern Sweden. The aim of the study was to investigate the differences in soil forming processes between stands of coniferous (spruce) and broad-leaved trees. The investigation did not show any differences in soil acidity, which was measured by pHH2O, pHKCl,

Populärvetenskaplig sammanfattning: Byggandet av en järnvägstunnel genom Hallandsåsen har orsakat sänkta grundvattennivåer på ett flertal platser i tunnelns närhet. Sänkta grundvattennivåer påverkar vegetationen i området och minskar även flödet i vattendragen uppe på åsen. Ett flertal våtmarker och fuktängar på Hallandsåsen har höga naturvärden och det finns därför ett stort intresse att skydda oEstablishing a railway tunnel through the mountain ridge Hallandsåsen in north-western Skåne, southern Sweden, may cause a lowered groundwater level in an approximately three kilometres wide area overlying the tunnel line. The "horst ridge" is caused by tectonic up-lift and the bedrock is rich in fissures and shear zones. There are at least two different aquifers in the area, one fissur

Populärvetenskaplig sammanfattning: Enligt livsmedelsverket måste ytvatten som infiltreras på konstgjord väg ha en verklig uppehållstid mellan infiltrationsplats och uttagsplats på 14 dagar eller längre för att klassas som grundvatten. I Hallstahammars kommun i Västmanland sker dricksvattenförsörjningen till stor del genom att ytvatten från Strömsholms kanal infiltreras i Strömsholmsåsen, en subakAccording to the Swedish National Food Administration, artificially recharged water must stay in the ground for at least 14 days in order to be classified as groundwater. In September November 1996, a tracer test was conducted in the part of the esker Strömsholmsåsen which runs through Hallstahammar, Västmanland. The purpose of the test was to decide the duration of staying of artificially recharg

Populärvetenskaplig sammanfattning: I det svenska urberget finns stora mängder av granit och andra magmatiska bergarter. Dessa magmatiska bergarter förekommer i både deformerade och odeformerade varianter. Majoriteten av de magmatiska bergarterna anses ha bildats genom att en oceanplatta har glidit ned under en kontinentplatta med hjälp av spridningsprocesser vid oceanryggarna. Oceanplattan smälteFine grained inclusions in the 1578 Ma Nordingrå rapakivi massif have been studied with respect to petrography, geochemistry and zircon age in order to see whether they belong to the same intrusion event as the granite, and whether they are different in mineral compositions or geochemical characteristics compared to the host granite. Such differences could indicate that fractionation processes hav

Popular summary: In my work I have studied the manganese ores at Bölet in Västergötland, southern Sweden. The ores at Bölet are of hydrothermal origin, which means that a hot fluid flushed through the bedrock and precipitated different salts and minerals. The purpose of the study was to determine the temperature of the precipitating fluids and to estimate their composition. To do so I examined mic

Populärvetenskaplig sammanfattning: Conodonter är stratigrafiskt användbara, fosfatiska mikrofossil, som påträffas i marina sediment mellan senkambrium till slutet av trias (520-210 Ma). Olika formtyper av conodonter, eller conodontelement, byggde tillsammans upp käkapparaten hos det lilla ål-liknande conodontdjuret, som numera räknas till chordaterna. Jag har undersökt förekomsten av conodontsläkSeven taxa of the conodont genus Ctenognathodus (Fay, 1959) sensu Viira, 1982b in the Silurian of Gotland have been described and their occurrence mapped geographically, stratigraphically and related to facies. In addition to C. murchisoni (Pander, 1856) three new species were found; C. n. sp. D, C n. sp. E and C n. sp. I with two subspecies, I and G. Two taxa formerly known as subspecies of Ligon

I samband med Skånes övergång till Sverige 1658 hamnade många danska adelsmän med sina jordegendomar i det nya svenska riket. Först på 1680-talet efter skånska kriget klargjordes deras juridiska och ekonomiska ställning samtidigt som en försvenskning av provinsen påbörjades. I uppsatsen utforskas den dansk-skånska adelns förändring och integration i det svenska riket 1680-1750. Utifrån den amerika

Populärvetenskaplig sammanfattning: Jag har studerat ungefär 450 miljoner år gammalt material från Cincinnati-området i USA. Materialet består av stenplattor av olika storlek, med fossila rester av olika havslevande organismer. Under tidsperioden Ordovicium låg den amerikanska kontinenten vid ekvatorn och dess inre täcktes av ett hav. Just i området kring Cincinnati avlagrades i detta epikontinentThe study aims to reconstruct the palaeoenvironments and faunas from six different localities in the area of Cincinnati, USA. The Upper Ordovician consists of limestones with intercalating mudstones. The faunas are rich and very diverse. The taxonomic composition and taphonomic indications are briefly described. The palaeoenvironment and faunal communities are reconstructed and compared to Bretsky

Populärvetenskaplig sammanfattning: När Sveriges Geologiska Undersökning (SGU) karterade nordöstra Skåne påträffades dels kalksediment i ett annars gnejsdominerat område, dels ett gyttjeliknande manganförande material i en husbehovstäkt i Broestorp, 2 km SSV om Sibbhult, NO Skåne. Syftet med min undersökning var att dokumentera och bestämma bildningen för moränskärningarna i täkten, utbredningen aThe study was made in Broestorp gravel pit with surroundings, 2 km SSV of Sibbhult, Southern Sweden. The tills and the underlying Cretaceous bedrock were investigated in a drumlin-shaped ridge striking approximately N30°E-S30°V and being 1000 m long and 150-250 m wide. Different types of manganiferous and ferruginous precipitates were found to be enriched at the contact between Cretaceous bedrock

In the past five years, many Scanian cities have been hit hard by flood damages, especially in conurbation areas. A changed Scanian climate with increased annual rainfall and more downfalls during summer months, is expected to worsen the outcome of flood damages. Therefore, there is a great need for damage prevention activities and climate adaptation work with particular interest for insurance com

Populärvetenskaplig sammanfattning: År 1949 upptogs en borrkärna vid Almbackens gård (Södra Sandby) öster om Lund. Kärnan visar ett tvärsnitt genom de sedimentära bergarter, som härrör från den tidiga och mellersta delen av den kambriska perioden. Den totala längden på kärnan är ca 31 m och är i mycket gott skick. Den nedersta delen, översta delen av underkambrium, utgörs av sand- och kalkstenar vThe uppermost Lower Cambrian and Middle Cambrian of the Almbacken drill-core, drilled 1949 in Södra Sandby, are described and correlated with other sections in Scania (the Gislövshammar-2 core and the Forsemölla, Gislövshammar and Brantevik sections). The core consists of Middle Cambrian bituminous alum shales with stinkstone lenses and three beds of fossiliferous limestone, the Andrarum, Exsulans

The Seve Nappe Complex of the Upper Allochthon contains parts critical to the understanding of the origin and evolution of the Scandinavian Caledonides. The metamorphic grade of the complex is generally amphibolite, locally eclogite facies. The protolith of the underlying Särv Nappes of the Middle Allochthon is very similar to that of parts of the Seve Nappe Complex. The studied area consists of m

Lead was an essential part of bullets used at shooting ranges in Sweden. This has lead to that many shooting ranges have elevated amounts of lead in the soil, ie. lead ground contamination. As lead causes severe health effects on humans and animals, and accumulates in the nature then this is of great concern. This contamination and its effects on humans is also very important since many of those s

Tetra Pak is the world’s largest producer of beverage cartons with an annual worldwide production of about 150 billion packages. They work actively with improving their recycling efficiency by setting recycling rate goals for the next three, six and nine years for each market. These goals have so far been educated guesses and there is a need for investigating what drives and predicts recycling eff

Summary: The aim of this study was to analyse how the composition and in particular the openess of the present-day landscape is reflected in pollen assemblages from surface sediment in lakes. The study is a continuation of an earlier pilot study including thirteen sites and a first step in an attempt to find a method of quantifying ancient cultural landscape in terms of surface areas from fossil p

This qualitative study is inspired by queer-feminist elaborations on normative and queer temporality, where I seek a temporal terminology of displacement in the context of migration in Sweden. The focus is on former asylum seekers from the region of former Yugoslavia, who in the 1990s, had years-long periods of uncertain residence statuses and unemployment. This interview-based study deals with re

Samples from the Danian were prepared for study of coccoliths, on one hand with Light Microscopy, on the other hand with Scanning Electron Microscopy to test the different advantages and disadvantages of these methods. Light Microscopy studies can be used for quantitative investigations and Scanning Electron Microscopy studies for quantitative and qualitative investigations of coccoliths. Scanning

A review of adaptations in fossil and extant mammalian carnivores has been made. Adaptations to different locomotor behaviours can be seen in the postcranial skeleton. Typically cursorial adaptations are long distal limb segments and restrictions in the mobility of the limbs to move in other directions than forward and backward. Diggers have fore limbs constructed for large out-forces. Climbers ha

Groundwater control monitoring programmes are established at sanitary landfills to document that the ground water, and surface water, are not being polluted by the landfill. The first part of this paper (a literature review) discusses the principal elements of a groundwater control monitoring programme, with focus on control principles, location of observations wells, or monitoring wells, indicato
