  1. 1. Improvement of Thermal Comfort in Buildings through Passive Design

    University dissertation from Lund University

    Author : Marcelino Januário Rodrigues; Lunds universitet.; Lund University.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Buildings; Sustainability; Energy Efficiency; Passive Design; Orientation; Shading; Ventilation; Materials; Temperatures; Thermal Comfort; Simulations; Retrofitting; Hot Humid Regions.;

    Abstract : In hot humid regions the high outdoor temperature has negative effects on the indoor temperature of buildings that are not designed to cope with the local climate. This leads to discomfort for the occupants. READ MORE

  2. 2. Method and technique development in peptide and protein mass Spectrometry

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kristina Håkansson; Uppsala universitet.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; electrospray ionization; peptide sequencing; Fourier transform ion cyclotron resonance; hydrogen deuterium exchange; protein structure; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Molecular Biotechnology; Molekylär bioteknik;

    Abstract : Mechanistic studies and applicability of several methods and techniques for studying peptides and proteins with mass spectrometry are presented. A model for the protein molecular ion formation in explosive matrix-assisted plasma desorption mass spectrometry is proposed, involving a contribution from the chemical energy release during conversion of the explosive, an enhanced protonation through collisions with products from the explosive decay, and electron scavenging by other products.

  3. 3. High-rate reactive magnetron sputter deposition and characterization of metal oxide films

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Maryam Kharrazi Olsson; Maryam Olsson; Uppsala universitet.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik; Materials science; Materialvetenskap;

    Abstract : Molybdenum oxide films with good electrochromic properties were produced by single- and dual-target sputtering. Dual-target deposition was shown to be able of yielding optically functional films at much higher rates than that for single-target depositions. READ MORE

  4. 4. Ti3SiC2 synthesis from TiC and Si powders

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Ida Kero; Luleå tekniska universitet.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science - Construction materials; Teknisk materialvetenskap - Konstruktionsmaterial; Engineering Materials; Materialteknik;

    Abstract : The aim of this work was to produce Ti3SiC2 from TiC and Si powders and to investigate process parameters with respect to optimised Ti3SiC2 yield. The reaction pathway of Ti3SiC2 formation and the thermochemical degradation reactions were examined. READ MORE

  5. 5. Effect of boron and hydrogen on microstructure and mechanical properties of cast Ti-6Al-4V

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Raghuveer Gaddam; Luleå tekniska universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titanium alloy; Metallography; Fractography; Castings; Low cycle fatigue; Hydrogen; Boron; Materials science - Construction materials; Teknisk materialvetenskap - Konstruktionsmaterial; Engineering Materials; Materialteknik;

    Abstract : Titanium and its alloys are widely used in applications ranging from aeroengines and offshore equipment to biomedical implants and sporting goods, owing to their high ratio of strength to density, excellent corrosion resistance, and biomedical compatibility. Among the titanium alloys used in aerospace, Ti-6Al-4V (an α+β alloy) is the most widely used, in applications in which the temperature may reach 350°C, at which point it retains good fatigue and fracture properties as well as moderate tensile strength and ductility.
