    Author : Ali Darwesh; Thorkild Maack Rasmussen; Nadhir Al-Ansari; Daniel Ask; Bernt Sigve Aadnøy; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bazian Block; Kurdistan; Iraq; Optimization; Drilling Parameters; Rate of Penetration; Wiper trips; Kicks; Pay zone; Bourgoyne and Young model; Exploration Geophysics; Prospekteringsgeofysik;

    Abstract : In the beginning of 2005, the ministry of natural resources in the Kurdistan region of Iraq dividedits territory into more than 50 oil blocks based on geological setting. These oil blocks were awardedlater to different international oil companies for oil investments based on Production SharingContracts (PSCs). READ MORE

  4. 17. FACING THE CHALLENGE OF SKIN PENETRATION - A STUDY ON LIPIDIC LIQUID CRYSTALLINE PHASES FOR DERMAL DRUG DELIVERY

    Author : Hanne Evenbratt; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 5-diol; liquid crystalline phases; N-Methyl-2-pyrrolidone; pentane-1; glyceryl monooleat; propylene glycol; dermal drug delivery; glyceryl monooleyl ether; cubic phase; reversed hexagonal phase;

    Abstract : The skin is a barrier which protects us against daily attacks of foreign substances. From a pharmaceutical perspective it is also an interesting delivery route with its large surface and possibility to reach the blood stream circumventing first passage metabolism. With the varied size, structure etc. READ MORE

  5. 18. Groundwater vulnerability assessment using process-based models

    Author : Riitta Lindström; Roger Thunvik; Pertti Vakkilainen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Database; Groundwater vulnerability; Hydrogeological environment; Process-based models; Penetration depth; Turnover time; Miljöteknik; Environmental engineering; Miljöteknik;

    Abstract : The focus of this thesis is on groundwater vulnerability assessment by process-based simulation models and data acquisition for these assessments. A modelling system for intrinsic groundwater vulnerability assessment in water supply areas was developed, consisting of flow- and transport models for the unsaturated zone and the groundwater zone, coupled to a geographical informa-tion system.

  6. 19. Dynamic Behaviour of Concrete Structures subjected to Blast and Fragment Impacts

    Author : Joosef Leppänen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : For protective structures, reinforced concrete is commonly used. Concrete structures subjected to explosive loading in a combination of blast and fragments will have very different response than statically loaded structure. READ MORE

  7. 20. On the Application of Surface Wave Surveys for Seismic Site Response Evaluation

    Author : Edwin Obando; Teknisk geologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface wave; MASW; seismic site response; ground motion; seismic transfer functions; shear wave velocity; site amplification; walk-away; near-field effect; dispersion curve.;

    Abstract : In sites where earthquakes occur, the use of surface wave methods represents a convenient and effective procedure for soil characterization. In particular, Multichannel Analysis of Surface Wave (MASW) has become a popular tool in many seismic micro-zoning projects. READ MORE
