Using an inclined screw brings many advantages compared to traditional methods, e.g. high load-bearing capacity, fast and easy montage and high fire resistance. This report contains a study of the influence end- and edge distances have on the load-carrying capacity in joints with inclined screws. Tests were carried out in order to determine if a few of the end- and edge distances proposed by Kevar

This report contains a theoretical study concerning composite construct design with steel and concrete and its mechanical and thermal interaction. The two primary advantages with this composition are the increase of the load-carrying capacity and its fire resistance. Composite construct elements are often used in the building process and there are several companies that offer a complete framework

Calculated deformations in glulam beams caused by moisture are based on linear moisture profile, this does not reflect reality. This report contains of a study where the moisture induced deformations are measured in three different test setups, simulating more realistic moisture exposure. After the beams are seasoned in RH 30 and 95 % the climate was changed, one group was in a moistening phase an

Läckage och spill från cisterner utgör de vanligaste orsakerna till förorening av grundvatten med petroleumprodukter. Bensin och dieselföroreningar sprids inte enbart längs grundvattenytan utan lösta beståndsdelar kan transporteras med grundvattnet relativt långa sträckor. Flyktiga kolväten förflyttar sig i den vattenmättade zonen beroende på föroreningens utbredning och fördelning. Flera tusen aSpills and leaks from storage tanks constitute the most common groundwater contamination source with petroleum products. Gasoline and diesel pools do not spread extensively along the water table, but dissolved constituents are transported in groundwater on relatively larger distances. Volatile hydrocarbons migrate in the vadose zone dependently on distribution and extent of the dissolved and pure

Konstgjord grundvattenbildning är en viktig teknik i vattenhushållningssammanhang och är idag en av de vanligaste och mest utbredda metoderna i världen för att öka vår grundvattenkapacitet. I många länder har den här tekniken använts under lång tid medan den i andra är i framåtskridande. Tekniken har använts i Europa sedan början av 1900-talet och är fortfarande en vanlig metod för grundvattenförsArtificial groundwater recharge is an important technology in water resources management and is nowadays one of the most common and rapidly spread world wide methods for increasing groundwater capacity. In many countries this technique has been employed for a long time, however in the others it is in progress. It has been used in Europe since the early 1900s, and is still a popular method municipa

Populärvetenskaplig sammanfattning: För 420 miljoner år sedan, under den tidsperiod som kallas för silurtiden, låg Sverige vid ekvatorn. Stora delar av landet var täckt av ett grunt och tropiskt hav där bland annat koraller, bläckfiskar, trilobiter och havsskorpioner trivdes. Även Gotland låg under havsytan och det var under denna tid som den kalksten som utgör öns berggrund byggdes upp. Förutom dThe Late Silurian Lau Event is one of the three major events identified in the Gotland strata. It is associated with one of the largest stable carbon isotope excursion recorded in the Phanerozoic, as well as rapid lithology changes, and extinctions and faunal turnovers among various fossil groups. In this study, early vertebrates (fishes) were investigated over the Lau Event interval. The study wa

Syftet med denna studie är att jämföra klassisk sång och jazzsång, vad som karaktäriserar de båda sångsätten och vilka möjligheter som ges i ett parallellt musicerande inom båda genrerna. Kvalitativa intervjuer har genomförts med fyra sångpedagoger som alla har kunskaper om undervisning inom både jazzsång och klassisk sång samt erfarenheter av eget musicerande. Resultatet av intervjustudien visar Title: The classical jazz vocalist- A study of classical singing, jazz vocals and the combina-tion of these two. The purpose of this study is to compare classical singing and jazz vocals. What character-ize them and what possibilities there are in singing and developing them both parallel? Interviews have been done with four singing teachers who all have experiences in both classical singing and j

Sångpedagoger har skilda uppfattningar om hur man bör förhålla sig till sångteknik och uttryck samt vad sångteknik egentligen innebär. Sångaren och författaren Thomas Hemsley anser att sång i första hand är ett känslomässigt uttrycksmedel och bör ta sin utgångspunkt i viljan att kommunicera. Detta menar han man alltid ska ha i åtanke när man utvecklar sin röst i övningar och repertoar. Hemsleys taThe voice of the heart – working with feelings, impulses and reactions in vocal pedagogics The singer and writer Thomas Hemsley believes that singing starts as a wish to express emotions through music. He considers singing to be a form of communication and believes singers should always keep this in mind when they make singing exercises and repertoire. Hemsley’s opinion about singing forms the bas

A lot of people suffer from nocturia which means that they have to get up in the mid-dle of the night to urinate. For the everyday healthy human this is not a serious prob-lem, they manage to go to the bathroom by themselves. But to the elderly population there is a risk involved. They could get hurt on the way to the bathroom or in many cases simply not wake up and urinate in their sleep. The exi

Detta arbete har som syfte att besvara två frågeställningar - hur ser lagstiftningen ut för miljökonsekvensbeskrivningar för planer och program i Sverige, och vilka krav kan ställas utifrån denna, samt hur dessa krav har uppfattats i genomförda miljökonsekvensbeskrivningar för planer och program? Detta görs genom en genomgång av lagtext, förarbeten, praxis och litteratur på området, en granskning This work aims to answer two questions - how does the legislation for environmental impact assessments for plans and programs in Sweden look like, and what demands can be made from this, and how are these requirements perceived in conducted environmental impact assessments for plans and programs? This is done through a review of the statutory text, legislative history, case law and literature, an
