  1. 1. You Bet! : An Investigation of Market Positioning by Online Gambling Firms and Drivers of their Customers’ Gambling Intention

    Författare :Jirka Konietzny; Esmail Salehi-Sangari; Albert Caruana; John B. Ford; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; gambling; UTAUT; PLS-SEM; anticipated enjoyment; perceived fairness; DICTION; lexical analysis; hierarchical clustering; Industrial Marketing; Industriell marknadsföring;

    Sammanfattning : Online gambling is a global multibillion dollar business that dwarfs all other forms of entertainment, and yet business and marketing research about it is scarce (Mizerski, 2013). The focus of gambling research has been on problem gamblers who ultimately represent a rather small, albeit important percentage of the gambling population. LÄS MER

  3. 2. Early age properties of self-compacting concrete - Effects of fine aggregate and limestone filler

    Författare :Oskar Esping; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pore pressure; autogenous deformation; self-compacting concrete; plastic shrinkage; BET; specific surface area; rheology; limestone filler;

    Sammanfattning : Self-compacting concrete (SCC) is a sensitive mix, strongly dependent on the composition and the characteristics of its constituents. It has to possess the incompatible properties of high flowability together with high segregation resistance, a balance made possible by the dispersing effect of water-reducing admixture combined with cohesiveness produced by a high concentration of fine particles.

  4. 3. Deactivation of commercial three-way catalysts: effect of the thermal ageing

    Författare :Anna Fathali; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BET; methane production from E85; NOx reduction by methane; Rhodium; TWC; OSC; Automotive exhaust control; Palladium; Aging;

    Sammanfattning : This licentiate thesis is a summary of my study on thermal deactivated commercial threeway catalysts (TWCs). The experiments were performed using gasoline and a E85 fuelmixture of 85 vol.% ethanol and 15 vol.% gasoline. LÄS MER

  5. 4. Specific surface area of some minerals commonly found in granite

    Författare :Isabelle E. Dubois; Maria E. Malmström; Bo Strömberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Granite; Mineral; Surface area; BET; Sorption; Particle size;

    Sammanfattning : The specific surface area, determined by the BET method, is a parameter often used to scale results of mineral studies of surface reactions in terms of rate and capacity to the field scale. Such extrapolations of results from small-scale laboratory experiments to the field-scale are important within many environmental applications. LÄS MER

  7. 5. Rhodium diesel-reforming catalysts for fuel cell applications

    Författare :Xanthias Karatzas; Lars J. Pettersson; James Spivey; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autothermal reforming; auxiliary power unit; BET; chemisorption; diesel; fuel cell; hydrogen; monolith; reforming catalyst; reformer design; Rh; RhPt alloy; TEM; TPO; TPR; XRD; XPS; zone coating; Chemical engineering; Kemiteknik;

    Sammanfattning : Heavy-duty diesel truck engines are routinely idled at standstill to provide cab heating or air conditioning, and in addition to supply electricity to comfort units such as radio and TV. Idling is an inefficient and unfavorable process resulting in increased fuel consumption, increased emissions, shortened engine life, impaired driver rest and health, and elevated noise. LÄS MER
