1. Developing a Test Method to Evaluate the Blackout Effect of Uncoated Curtains at Varying Angles
Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : This study aimed to explore the integration of varying angles in small-scale measurements and assess the light transmission performance of uncoated curtains. A total of four curtains were evaluated: blackout curtain samples 1 and 2 had a weft satin structure, while daytime curtain samples 3 and 4 consisted of a twill structure. LÄS MER
2. Experiments and simulations of gas flow through a NiCd battery
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This report describes the thesis work carried out regarding experiments and simulations of the gas flow through a NiCd battery. The objective of the work was to investigate how different geometries of the flip top vent on the battery and the level of porosity of the flame arresting disc impacted the amount of potassium carbonate created at the outlet of the vent.

4. Design av ångexplosionsreaktor : Utformning av ångexplosionsreaktor för laborativt bruk
Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)Sammanfattning : Förbehandling av lignocellulosa genom ångexplosion är en förbehandling av biomassa som förändrar strukturen i fibrernas cellväggar. Vid förbehandlingen värms biomassa med mättad ånga under tryck till minst 140 ˚C, detta leder till att flyktiga ämnen avgår från biomassan. LÄS MER
5. Quality of Spent Mushroom Compost Amended with Organic Material- Effect on Nutrient Content and Plant Growth
Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Peat, as a non-renewable growing media, poses environmental concerns due to extraction and decomposition processes, leading to increased greenhouse gas emissions. Alternatives growing media with potential to replace or reduce the use of peat are of great need. LÄS MER
