1. 16. Wet Spinning of Lignin and Cellulose Precursor Fibers Using Cold Sodium Hydroxide Dissolution

   University essay from KTH/Fiber- och polymerteknologi

   Author : Nazariy Voytyuk; [2022]
   Keywords : Alkaline Dissolution; Cold Alkali Process; Lignin; Precursor Fibers; Wet spinning; Alkalisk upplösning; Kall alkaliprocess; Lignin; Prekursorfibrer; Våtspinning;

   Abstract : Användningen av cellulosa och lignin för prekursorfibrer (PF) för kolfibrer (CF) är ett mycket intressant forskningsområde på grund av den stora miljöpåverkan som dagens PF-fossilbaserade råvara PAN har. Denna avhandling fokuserar på att utveckla PF med ett kallt NaOH-upplösningssystem med cellulosakoncentrationer från 4,5 till 5,5 viktprocent med varierande massaviskositet och tillsats av lignin från 0-40 viktprocent jämfört med cellulosa.

3. 17. Blood interactions with bioactive peptidefunctionalized nanocellulose : An evaluation of the activation of the coagulation and complement system

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Vanisha Bansal; [2022]
   Keywords : ;

   Abstract : A current trend utilizing the biomedical approach in the field of wound care is focused on the increased potential to develop wound healing materials designed to address specific types of wounds or underlying pathologies to achieve improved healing. The work presented in this thesis evaluates the blood response to wood-derived nanocellulose functionalized with a peptide, with the ultimate aim of characterizing the material as a potential wound dressing for chronic wound care.

4. 18. Microvesicles in human reproduction and their role in Assisted Reproductive Techniques

   University essay from Uppsala universitet/Institutionen för medicinsk cellbiologi

   Author : Hala Sawas; [2022]
   Keywords : In Vitro Fertilization; Venous Thromboembolism; Fetuin B; Ovastacin; Flow Cytometry;

   Abstract : Infertility is a problem that could be treated by using In Vitro Fertilization (IVF). This procedure starts by increasing estrogen levels and then retrieving oocytes. However, studies have showed an increased risk for venous thromboembolism (VTE) and lung embolism that is correlated with the rising levels of estrogen. READ MORE

5. 19. Characterization of a novel EPHB2 R155C mutant with respect to its proteolytic cleavage by TF/FVIIa

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Ece Akcan; [2021]
   Keywords : cancer; colorectal cancer; CRC; ephrin receptor; EPHB2; tissue factor; TF; TF FVIIa; cleavage; cell repulsion;

   Abstract : EPHB2, an ephrin receptor (EPH) from receptor tyrosine kinase (RTK) family, is one of the substrates for tissue factor (TF) - coagulation factor VIIa (FVIIa) complex and it is cleaved in its ectodomain. EPHB2 cleavage is important for ephrin receptor (EPH) - ephrin ligand (EFN) signaling and cell repulsion. READ MORE

6. 20. Cradle-to-Gate LCA of Water Treatment Alternatives : A case study performed for Norrvatten’s future waterwork expansion

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Siddharth Selvarajan; [2021]
   Keywords : Life cycle assessment; Water purification method; Potable water production; Microbiological barrier; Activated carbon; Sludge separation; Livscykelbedömning; Vattenreningsmetod; Produktion av dricksvatten; Mikrobiologisk barriär; Aktivt kol; Slamavskiljnin;

   Abstract : Norrvatten is a municipal association which owns a water treatment plant capable of supplying good quality drinking water to the consumers in the associated neighbouring municipalities. After preliminary investigations for the future year of 2050, there were estimates which suggest a potential water quality degradation in the lake which supplies the raw water for treatment due to uncertain future climatic conditions and other forms of pollutions from the surrounding.
