  1. 1. Stability improvement to a ruthenium catalyst for partial oxidation of methane

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Melker Axelsson; [2023]
    Keywords : catalysis; reaction engineering; kinetics; partial oxidation; chemical engineering; Technology and Engineering;

    Abstract : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. READ MORE

  3. 2. Luckhuggning, bränning och skalbaggar restaureringsåtgärdernas påverkan på de rödlistade skalbaggsarterna i Sverige

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Katja Frostgård; Gustaf Lydén; [2023]
    Keywords : artrikedom; abundans; biodiversitet; restaurering; naturvårdsbränning; luckhuggning; rödlistade arter; skalbaggar;

    Abstract : Det skogsbruk som idag bedrivs på majoritet av den svenska skogsmarken har förändrat skogens struktur och variation; skogens heterogenitet har minskat. Detta påverkar en del av de skogslevande arterna negativt, och har bidragit till att många arter har minskat i sin utbredning och nu är rödlistade. READ MORE

  4. 3. A Cost Benefit Analysis of Continuous Cover Forestry in Djurholmen, Skåne

    University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Moa Morency; [2023]
    Keywords : continuous cover forestry CCF ; clear-cut forestry CF ; cost-benefit analysis CBA ; ecosystem services; climate mitigation; timber production; Norway Spruce Picea abies ; Earth and Environmental Sciences;

    Abstract : Forests and forest products are important, not just for timber production, the forest ecosystem plays several important roles, such as water purification, carbon sequestration for climate mitigation and recreational values. How the forests are managed varies throughout the globe, in Sweden the most used system is the clearcutting system (CF), however continuous cover forestry (CCF) is gaining popularity and is being tested in several places.

  5. 4. Differences and similarities in stand characteristics after prescribed burning and wildfire : implications for conservation of forest biodiversity

    University essay from SLU/Dept. of Ecology

    Author : Hannah Sophie Jakob; [2023]
    Keywords : coarse woody debris; conservation; biodiversity; boreal forest; Daldinia loculata; Fennoscandia; prescribed burning; regeneration; wildfire; woodpecker;

    Abstract : 1. Wildfires are a natural disturbance in the boreal forests of Fennoscandia and have shaped and formed forests in the past, resulting in very heterogeneous forests containing large amounts of dead and living trees in various age classes. READ MORE

  6. 5. Design of a modular small-scale PMMA/Air hybrid rocket research engine

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Gustaf von Platen; [2023]
    Keywords : hybrid rocket engine; PMMA combustion; rocket engine design; combustion diagnostics; rocket engine; regression rate; preliminary design definition; hybrid rocket engine simulation; gaseous oxidizer; transparent rocket engine;

    Abstract : Rocket propulsion using the hybrid-propellant scheme is a technology that offers much promise in applications where high-performance liquid rocket engines are deemed too complex and solid rocket motors are considered to lack performance or safety. However, despite extensive research, there is still a lack of knowledge in the theoretical aspects of hybrid rocketry, especially in the area of fuel-oxidizer mixing and fuel regression rate.
