1. Warhead penetration in concrete protective structures
Sammanfattning : The analysis of penetration of warheads in concrete protective structures is an important part of the study of weapon effects on protective structures. This type of analysis requires that the design load in the form of a warhead is determined, and its characteristic and performance within a protective structure is known. LÄS MER
2. Alkylglucosides - physical chemical properties
Sammanfattning : The aim of this study is to characterise the physical-chemical properties of alkylglucosides. Alkylglucosides are non-ionic surfactants synthesized from glucose and a fatty alcohol. The glucose molecule constitutes the hydrophilic head group and the fatty alcohol constitutes the hydrophobic tail. LÄS MER
3. Grouting of Hard Rock with Gelling Liquids, Field and Laboratory Studies of Silica sol
Sammanfattning : Recent grouting projects in Sweden have concentrated on the grout itself. The only grout normally used in Sweden is a cement-based one. During the past 10 years, the acceptable flow of water into tunnels has been significantly reduced. The current requirements mean that an average fracture aperture of around 0. LÄS MER
4. Characterisation of Fractured Rock for Grouting Using Hydrogeological Methods
Sammanfattning : Sealing of tunnels by grouting demands knowledge concerning the fractured rock and the grout, followed by an appropriate choice of strategy and equipment. In this thesis, the characterisation of rock is the main issue and, since it addresses the engineering problem of producing a description for grouting, the properties of grout and the grouting procedure need to be considered.

5. IronArc a New Process for Pig Iron Production : A Numerical and Experimental Investigation Focusing on Mixing
Sammanfattning : I den här studien så var syftet att undersöka omrörningen och relaterade fenomen i den nyutvecklade IronArc processen. Processen använder sig av gasinjektion genom plasmageneratorer för att smälta och reducera en slagg bestående av järnoxid. LÄS MER
