  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

  3. 3. 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.

  4. 4. 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

  5. 5. “Two brains are often better than one, probably”: Adult ESL learners’ paired and individual lexical inferencing task performances, in relation to L2 proficiency

    University essay from Lunds universitet/Masterprogram: Språk och språkvetenskap

    Author : Elin Nylander; [2019]
    Keywords : Lexical inferencing; L2 proficiency; task-based language learning; collaboration; sociocultural theory; dyadic patterns of interaction; Languages and Literatures;

    Abstract : This research concerns lexical inferencing (LI), i.e., the ability to infer the meaning of unknown words in a running text (Haastrup, 1991). Despite its advantages, there is little research on LI as a collaborative effort. READ MORE
