1. 1. Fibres from agricultural hemp waste

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Ella Kärkkäinen; Åsa Älgbrant; Simon Kronberg; [2021]
   Keywords : Hemp fibres; hemp residue; unretted hemp; nonwoven hemp;

   Abstract : There is an increasing demand for natural fibres in the textile industry as a consequence of the negative impact of the industry on the environment. Svensk Hampaindustri (SHI) is currently growing hemp in Sweden for its seeds. This leaves residue in the form of hemp stems that could be processed for textile products. READ MORE

3. 2. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

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

   Author : Jannek Hansen; [2021]
   Keywords : Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

   Abstract : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. READ MORE

4. 3. Shear stiffness of cross laminated timber diaphragms - A study of the influence of connection and member stiffness

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Gustaf Olausson; [2021]
   Keywords : Technology and Engineering;

   Abstract : Since ancient times, buildings have been constructed with the use of timber and during the modern era, new types of timber products have been developed. Today, more constructions, especially residential buildings are being built with timber as the main load-bearing material. READ MORE

5. 4. Test setup for LDMX HCal readout

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Joshua Greaves; [2020]
   Keywords : Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

   Abstract : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.

6. 5. The applicability of agricultural fibres in industrial cleaning cloths : in the aspects of processability and sustainability

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Liv Walker; Karin Essén; [2020]
   Keywords : Nonwoven; Industrial cleaning cloth; Agricultural fibres; Bast fibres; Polyester; Single-use; Nonwoven; Industriella rengöringsdukar; Naturliga fibrer; Bastfibrer; Polyester; Engångsartiklar;

   Abstract : This study has its background in the EU directive, the ‘Single-Use Plastics Directive’. The directive was initiated due to the environmental impacts that the oceans suffer due to plastic waste. The directive presents the most common single-use products found as waste in the oceans, including wipes and cloths. READ MORE
