  1. 1. Reduction of Set-recovery of Surface densified Scots Pine by Furfuryl Alcohol

    University essay from Luleå tekniska universitet/Träteknik

    Author : Lei Han; [2019]
    Keywords : surface densification; set-recovery; hardness; furfuryl alcohol;

    Abstract :  For wood products such as flooring and worktop, only one surface is normally exposed in their use, and the mechanical properties like hardness and wearing resistance of that surface is then important. Since mechanical properties are strongly related to the density, surface densification, i.e. READ MORE

  2. 2. Alternative oxidase respiration in the mycorrhizal fungus Laccaria bicolor

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

    Author : Hilda Mikaelsson; [2019]
    Keywords : L. bicolor; mycel; ektomykorrhiza; cellandning; AOX; alternativt oxidas; cytokromoxidas; cyanid; mycelium; ectomychorriza; respiration; alternative oxidase; cytochrome oxidase; salicylhydroxamic acid; n-propyl gallate; cyanide;

    Abstract : The temperature on Earth is rising, and one of the main drivers is anthropogen-ic greenhouse gases such as carbon dioxide (CO2). The world’s forests act as carbon sinks, binding carbon into their biomass. The net carbon assimilation is determined by the uptake and release of CO2 through the processes of photo-synthesis and respiration. READ MORE

  4. 4. An introduction to some ordinary differential equations governing stellar structures

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Yani di Giovanni; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : The Lane-Emden equation is a non-linear differential equation governing the equilibrium of polytropic stationary self-gravitating, spherically symmetric star models; $${\frac {1}{\xi ^{2}}}{\frac {d}{d\xi }}\left({\xi ^{2}{\frac {d\theta }{d\xi }}}\right)+\theta ^{n}=0.$$ In the isothermal cases we have the Chandrasekhar equation: $${\frac {1}{\xi ^{2}}}{\frac {d}{d\xi }}\left({\xi ^{2}{\frac {d\psi}{d\xi }}}\right)-e^{-\psi}=0$$ After having derived these models, we will go through all cases for which analytic solutions are achievable.

  5. 5. How Stellar Tides Affect Planet Evolution

    University essay from Lunds universitet/Astronomi

    Author : Madison Green; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Planets that orbit their host star closely experience tidal forces due to the strength of gravity not being uniform all over the planet. This leads to effects such as tidal spin synchronization, tidal eccentricity damping and tidal semi-major axis damping. READ MORE
