1. 1. När hjärtat sviktar : Patientens vardagliga svårigheter med hjärtsvikt.En litteraturöversikt med kvalitativ ansats

   Kandidat-uppsats, Jönköping University/HHJ, Avdelningen för omvårdnad

   Författare :Enaam Allamadani; Rama Hennawi; Shaima Alshalabi; [2024]
   Nyckelord :Chronic heart failure; patient; person-centered care; and well-being; kronisk hjärtsvikt; patient; personcentrerad omvårdnad och välbefinnande;

   Sammanfattning : Bakgrund: Hjärtsvikt är en folksjukdom hos ca 64 miljoner individer världen över och antal drabbade beräknas stiga. Vid hjärtsvikt förekommer olika typer av svårigheter som kan vara fysiska, psykiska eller psykosociala och som kan påverka patientens vardag samt patientens välbefinnande trots symtomlindring.

3. 2. Drop-weight impact tests on reinforced concrete beams

   Master-uppsats, KTH/Betongbyggnad

   Författare :John Abdalnour; Milad Saliba; [2023]
   Nyckelord :;

   Sammanfattning : This master's thesis aimed to investigate the behaviour of reinforced concrete beams under dynamic loading conditions, specifically focusing on understanding shear failure. The study was conducted with KTH Royal Institute of Technology, the Swedish Fortifications Agency, and Tyréns. LÄS MER

4. 3. Rapid expansion of roof mounted PV systems in commercial facilities - How can they be insured?

   Master-uppsats, Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Författare :Erik Lindén; [2023]
   Nyckelord :PV system fires; PV component failures; PV regulations; future PV regulations; PV risk assessment; PV risk evaluation; PV insurance price; Technology and Engineering;

   Sammanfattning : PV system components that are exposed to unmanageable strain can be overheated, which subsequently results in a fire ignition. Common failure factors are poor component quality, mechanical exposure due to natural phenomena and poor craftmanship. The underlying problem is that PV regulations are lacking in quality or are non-existent. LÄS MER

5. 4. Wet Spinning of Cellulose-Lignin Precursor for Carbon Fibers : Effect of Coagulation Bath Composition & Spin Finish

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

   Författare :Julia Sundmark; [2023]
   Nyckelord :Carbon fiber; Cold alkali; Cold NaOH; lignin; cellulose; wet spinning; Kolfiber; kallalkali; lignin; cellulosa; våtspinning;

   Sammanfattning : Carbon fibers (CF) are a material with a composition of over 90% carbon, which has high mechanical properties and low density. This unique combination of properties makes it requirable in applications such as vehicles, aerospace, wind power, and space industries. Commercially made CF are made using the fossil raw material polyacrylonitrile (PAN). LÄS MER

7. 5. Characterisation of an Additively Manufactured Self-Sensing Material Using Carbon Fibre Sensors

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Alain Williamson; [2023]
   Nyckelord :Additive Manufacturing; Self-Sensing Material; Carbon Fibre Sensors; Structural Health Monitoring; Space Applications; 3D-Printed Continuous Carbon Fibre Filament; Strain Sensor; Mechanical Properties; Electromechanical Properties; Tensile Strength; Failure Strain; Base Resistance; Gauge Factor; Linearity; Systematic Literature Review; Material Selection; Mechanical Design; Material Development; Feasibility Study;

   Sammanfattning : Increasing demand for structural health monitoring in space highlights the need to make the creation of these systems more accessible. This study investigates the potential of additive manufacturing to achieve this goal by characterizing a self-sensing material made of a commercially available 3D-printed continuous carbon fibre filament.
