Sammanfattning: Tre kommunala vattentäkter med konstgjord infiltration i sydöstra Småland har studerats. I Emmaboda vattentäkt har infiltrationsvattnet alkaliserats med släckt kalk sedan 1977 och i Kosta med soda sedan 1985. Målsättningen med studien har varit att påvisa förändring i totalhårdhet, alkalinitet samt aluminium- och järnhalt för det konstgjorda grundvattnet sedan alkaliseringen påbörjA water chemistry study has been made at three public water supplies with artificial recharge in the county of Småland in the south of Sweden. At the water system of Emmaboda the surface water has been treated with slaked lime and at the water system of Kosta with soda ash. The aim of this study was to show whether the alkalization has changed the quality of the artificial ground water regarding i

ABSTRACT Author: Nicklas Bogren Title: Professionals view on cannabis use Supervisor: Eva-Malin Antoniusson During my practice in 2008 I heard a discussion about all the risks and all the consequences of cannabis use from both old and young employees. They did all have the same education as me, and referred to the gateway theory. I thought this was strange, because I have read both research and li

The municipal dump of Helsingborg, located next to Filborna in the north-east area of the town is subject to plans of expansion. A watersupply is situated 3 km's north-east of the dump. The purpose for this investigation is to make clear weather there is a possibility that water soaking through the dump is liable to contaminate the watersupply. To get a fair view of the groundwaterflow in the

Glacial and marine geomorphological features have been studied and mapped on the south coast of Gilsfjördur West-Iceland. In this region the main Icelandic ice-sheet is supposed to have met with a separate Vestfirdir ice-cap. Fossiliferous sediments in the area are assumed to be of Late Weichselian age. Sediment terraces in the valley mouths indicate that smaller glaciers existed in the valleys al

En wollastonitförekomst vid Stor Hulta gruvor i närheten av Nora har undersökts. I den nedlagda gruvan har tidigare skarnjärnmalm tillhörande leptitformationen brutits. I jämförande syfte har även wollastonit från Akatjvare i Tjåmotisområdet undersökts. Detta är LKAB:s prospekteringsobjekt och är beläget i Jokkmokks kommun. Resultaten för detta material, som utgörs av fyra stuffer av dubbel knytnäThe wollastonite occurrence at Hulta is a skarn deposit associated with iron ore within the Leptite Formation of central Sweden. Wollastonite is found in carbonate layers within the leptite and the rocks have been subject to regional metamorphism. These layers are normally approximately 10 cm thick. Corelogging, microscopic studies and X-ray diffraction show a varied composition of the rock, with

Gränsöverskridande e-handel ger upphov till en del juridiska problem inte minst då tvister uppstår mellan avtalsparterna. Något som diskuterats särskilt bland rättsvetare världen över, är vilket lands domstol som ska ha jurisdiktion när avtalstvister uppstår i detta sammanhang. I Bryssel I-förordningen finns vissa delvis tvingande domsrättsregler som är tillämpliga då avtalstvister uppstår mellaCross-border e-commerce gives rise to a number of legal issues. One particular difficulty, discussed by legal commentators all over the world, is how to allocate jurisdiction when disputes arise over e-contracts. The Brussels I Regulation contains certain semi-mandatory jurisdiction rules which apply in relation to contract disputes between traders and consumers. These rules give the consumer a r

Sammanfattning: Detta arbete består av tre mer eller mindre självständiga delar. I den första delen presenteras de olika systemen för utvinning och lagring av naturvärme. De två andra delarna innehåller en regional och lokal kartläggning, där tillgångarna bedöms. Valda områden är Kalmar län respektive Västerviks kommun. Naturen omkring oss kan användas både för utvinning och lagring av värme. Med During the last 15 years the heatpump technology has developed rapidly in Sweden due to the increasing prices of energy. One of the major sources for the heatpump is low-temperature energy from the enviroment. This might be heat from groundwater, surface water, soil or bedrock. The purpose of this report is to give an overview of the technical systems, and to evaluate the natural energy-resources

Summary: Lake Bussjö is an 0.3 hectare large kettle hole in a hummocky morain landscape four kilometers north of Ystad. The purpose of this study is to investigate the stratigraphy and reconstruct the highest water level. Another task is to estimate the rate of farmland advance on earlier grazingland and swamps. Furthermore, to calculate the future development of the lake. To make the stratigraphy

The Vomb Plain in central Skåne is a large sand and gravel field. lts youngest glacifluvial deposits have been investigated from a sedimentological point of view in order to define proximal to distal environments of the ancient braided river system. The following parameters have been used in studying the sandurfield: The average grain size composition and the maximum size of clasts at sites from d

Summary: The purpose of this paper is to give a petrographic and mineralogic description of a dyke complex, consisting of a metadiabase and a quartz keratophyre. The type locality is the northern part of the Kiirunavaara apatite-rich iron ore, situated in northern Sweden. In this part of the mine, the dyke complex has caused problems with rock stabil ity and water inflow. The dyke is well mapped f

Ö. Silvberg och Vallberget are two sulphide-ore mines immediately to the west of the town Säter in Dalarna. They are found in a NE-SW trending orebearing zone in the Leptite-formation. An area extending about 6 km in the NE-SW and 2 km in the perpendicular direction has been mapped. It consists of different types of volcanics, which chemically correspond to rhyolites (Na-rich, K-rich and alkali-in

lnvestigation of weak gravel for road construction has been going on at VTI for many years. The overall aim has been to find test methods that correspond with what happens in the road and that are easy to use in any road laboratory. Following methods have been used in this investigation: planetarytype mixer for wear tests, freeze-thaw variation for weathering tests, Californian Bearing Ratio (CBR)

In Bjärsjölagård layer 1b the genus Neobeyrichia is represented by Neobeyrichia spinulosa (Boll) and Neobeyrichia regnans Martinsson. N. spinulosa dominates strongly. It is here redescribed and the appearence of the last moulting stage is described. N. spinulosa was a marine, benthic species. Previous reports of N. spinulosa from Gotland (Sweden) and Denny's Formation (eastern USA) are wrong.

The Vitabäck clays, the Jurassic - Cretaceous transitionai beds in Sweden, contain brackish water faunas with close affinities to their counterparts in north-western Europe. The faunas are dominated by the bivalve genera Myrene and Neomiodon. There is no evidence for limnic or marine conditions, which previously has been assumed. The molluscan assemblages indicate somewhat differing salinity condi

Summary: The Kiruna ore is situated in northernmost Sweden, and it is one of the largest iron ore deposits that is known in the whole world. Small amounts of cobalt occur in the ore. This paper is devoted to the study of the distribution of cobalt in the Kiruna ore. Results from studies under the polarizing microscope in both transmitted and reflected light in addition to chemical wholerock analys

A classical field of Quaternary research in Skåne is the subdivision of tills in different stratigraphical units; each one related to a certain ice-stream. North of Svalöv, western Skåne, there is a very sharp boundary between two till-types, usually called Low Baltic till and Northeastern till. More recent investigations carried out by Lagerlund (1980) in other parts of western Skåne have showed

This paper is an examination work, initiated by E. Lagerlund, who has carried out investigations on the lithostratigraphy at the Margreteberg site on Rydsbjär, southern Halland. Lagerlund et.al.(l984) found a sea level at 50m a.s.l at the time of the deglaciation in the area. A regression down to at least 35m a.s.l was followed by a transgression to the highest shore line.
