16. The Effect on Mechanical Properties in Biochar Replaced Cement & Aggregate in Concrete Before and After Fire Exposure
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Concrete is good as a construction material regarding fire and its properties regarding strength. However, the concrete expands and cracks due to fire resulting in structural damage. According to the literature the concrete usually loses its strength during and after fire exposure due to themechanical and physical changes. READ MORE

17. Studie av toppskyddet EcoTall på ett ungskogsbestånd i Västmanland
University essay from SLU/School for Forest ManagementAbstract : Viltskador är problematiska för skogsbruket då det medför defekter som orsakar stora ekonomiska förluster. Det är framförallt älgens betesskador på tall som är ett problem för skogsbrukets ekonomi och skadorna förväntas inte bli färre med tiden. READ MORE

18. Viscoelasticity of transparent wood-polymer biocomposites : Measuring the time-dependence of a delignified birch and poly(methyl methacrylate) composite’s mechanical properties, using digital image correlation
University essay from KTH/MaterialvetenskapAbstract : The viscoelastic behavior of a delignified birch and poly(methyl methacrylate) (PMMA) composite was investigated, in an effort to learn more about the mechanical properties of transparent wood-polymer biocomposites. Tensile creep tests with constant load were performed for native wood, non-delignified, and delignified wood-polymer composites. READ MORE

19. Rate-dependent effects on the mechanical behaviour of paper
University essay from KTH/HållfasthetsläraAbstract : It is established that paper properties depend on the loading rate. The rule of thumb is that the in-plane strength and stiffness increases about 10\%, when the strain rate increases by a factor of 10. Converting of paperboard into packages requires creasing of the paperboard followed by folding to make 3 dimensional packages. READ MORE

20. Protein Recovery from Alkaline Extracts: A Comparative Analysis of Isoelectric Precipitation and Ultrafiltration
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : Proteins are one of three macro-components of a diet. An increasing demand for products that can be a complete protein source exists. The vulnerability of the current food system towards environmental impacts and the inability to keep up with the rising population has shifted the focus on valorising underutilised by-products of the food industry.
