1. Impact of BPA, BPF and Mixture N1 on DNA-Methylation of GRIN2B and NR3C1 during human neuroprogenitor cell differentiation
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Fysiologi och miljötoxikologiSammanfattning : Endocrine disrupting chemicals (EDCs) are ubiquitous and their adverse impact on nature, wildlife and humans is extensively researched. We are constantly exposed to EDCs, such as the widespread and extensively researched Bisphenol A, as well as its substitute Bisphenol F, which is coming into wider use, even though it is much less is researched and limited information is available about its endocrine effects.

2. Evaluation of critical instrument parameters for the transfer of LC-MS quantification methods between LC-MS/MS and Orbitrap MS
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Transferring analytical methods is crucial in chemical laboratories. The need for the transfer may arise for different reasons such as sharing data between different laboratories, replacement or upgrade of analytical instrument, or limited instruments available etc. The performance and sensitivity of different instruments may vary.

3. An Investigation of The Link Between Endocrine Disruption and Developmental Neurotoxicity Induced by Environmental Pollutants : In Zebrafish Embryos
Master-uppsats, Uppsala universitet/Institutionen för cell- och molekylärbiologi; Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Endocrine-disrupting chemicals (EDCs) are known to cause endocrine disruption (ED), developmental neurotoxicity (DNT), infertility and impaired embryo development. EDCs do therefore impose a threat to humans, wildlife and the environment. LÄS MER
4. Inledande utvärdering av epoxibaserad livstidsförlängning av fjärrvärmerör : Relining av kolstål med en polyamidhärdande lösningsmedelsfri epoxi
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - ÅngströmSammanfattning : Degradation of steel pipes in district heating systems is often a result of corrosion processes. To maintain the power in the systems the pipes gets replaced when they have been worn-out, resulting in high cost and long service time due to excavation. LÄS MER
5. Catalytic synthesis of benign bisphenols
Kandidat-uppsats, KTH/KemiSammanfattning : This study analyzes the reactivity and selectivity of Friedel-Crafts alkylations using benzylic alcohols and phenols in the presence of a Lewis acid, to synthesize methoxylated bisphenols as a benign alternative to BPA. The degree of methoxylation on the electrophile appears to affect the yield of the reaction while the degree of methoxylation on the nucleophile appears to affect the selectivity. LÄS MER
