1. 21. Co-pretreatment of spruce and poplar for ethanol production - Effects of mixed feedstocks on pretreatment and enzymatic hydrolysis efficiency

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Hanna Jovanovic; [2017]
   Keywords : Biofuels; Bioethanol; Second generation bioethanol; Poplar; Spruce; Enzymatic hydrolysis; Pretreatment; Lignocellulose; Chemical Engineering; Kemiteknik; Technology and Engineering;

   Abstract : Oil is very important for today’s society and the transportation sector is almost completely dependent on this material. Unfortunately, it affects the level of greenhouse gases negatively which in turn contribute to global warming. READ MORE

3. 22. Örebro Market hall : A second chance at a new life

   University essay from KTH/Arkitektur

   Author : Hillevi Robertsson Quinn; [2017]
   Keywords : Market hall; addition; reuse; light transmission; natural light; restore; Örebro; Saluhall; tillägg; återanvändning; ljusföring; naturligt ljus; återställa; Örebro;

   Abstract : How does one restore the original life and program to a building that has been repurposed several times over the preceding decades? In the 1950s, Örebro had a fine market hall with great light and spaces. In the 1970s a supermarket took over the space, and the old roof with its skylights was demolished, but the original construction with its beams and pillars remains today. READ MORE

4. 23. Design of a 3D training equipment : Development of a new exercise equipment to prevent injuries among sedentary workers

   University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

   Author : Ida Jakobsson; [2017]
   Keywords : 3D training; Sedentary Worker; Physical Activity; Motivation; Industrial Design Engineering; Usability; 3D-Träning; Stillasittade Arbetare; Fysisk Aktivitet; Motivation; Teknisk Design; Användbarhet;

   Abstract : Low-intensity and sedentary work have become more common in work life the last decades. More and more people get health problems as stress, lack of well-being and decreased work performances. Neck, shoulders, and arms are the most affected areas because of low activity for a longer time. READ MORE

5. 24. High Accuracy Relative Luminescence Quantum Yield Measurements of Upconverting Nanoparticles

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Author : Björn Thomasson; [2016]
   Keywords : Upconverting Nanoparticles; Biomedical imaging; Luminescence tomography; Luminescence imaging; Engineering; Physics; Engineering Physics; Photonics; Cancer; Cancer detection; Cancer diagnostics; Laser Engineering; quantum yield; imaging; upconverting; Biophotonics; Single Point Tomography; Relative Luminescence Quantum Yield Measurements; Energy transfer upconversion; Nanoscience; Luminescence; Imaging of biological tissue; Upconversion; Beam profile evaluation; Beam profile; UCNP; UCNPs; Nanoparticles; Technology and Engineering;

   Abstract : The name Upconverting nanoparticles refers to a novel category of luminescence emitters that are capable of generating visible luminescence upon excitation with noncoherent and longer wavelength monochromatic near-infrared light, at excitation fluence rates as low as 1-103 W/cm2. This unique optical behaviour is of great interest to researchers as it could potentially allow for virtually autofluorescence free luminescence imaging of living tissue. READ MORE

6. 25. The behaviour and movement of dairy calves in low light intensities

   University essay from SLU/Dept. of Animal Nutrition and Management

   Author : Emelie Battersby; [2016]
   Keywords : light intensity; calves; behaviour; locomotion;

   Abstract : According to the Swedish welfare act, cattle stables must have inlet of natural light and artificial light that do not disturb the animals’ natural behaviour and diurnal rhythm, dairy cows should also be provided with light at night. However, there are no specific recommendations on light programs for calves. READ MORE
