1. 1. Image Segmentation and Object Identification in Cancer Tissue Slides from Fluorescence Microscopy

   University essay from Uppsala universitet/Avdelningen Vi3

   Author : Sebastian Eriksson; Fredrik Forsberg; [2023]
   Keywords : image analysis; cancer research; fluorescent microscopy; image segmentation; bildanalys; cancerforskning; fluorescensmikroskopi; bildsegmentering;

   Abstract : In cancer research, there is a need to make accurate spatial measurements in multi-layered fluorescence microscopy images. Researchers would like to measure distances in and between biological objects such as nerves and tumours, to investigate questions which includes if nerve distribution in and around tumours can have a prognostic value in cancer diagnostics.

3. 2. Ecological risk assessment of pesticide use in rice farming in the Mekong Delta , Vietnam

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Bubaraye Ohiosimuan Dirikumo; [2023]
   Keywords : Pesticides; Ecological Risk Assessment ERA ; rice farming; Mekong Delta; PRIMET Model; Exposure Toxicity Ratio ETR ; species sensitivity distribution SSD ; predicted environmental concentrations PECs ;

   Abstract : Pesticide use in rice farming is a common practice in the Mekong Delta and poses ecological risks to aquatic organisms, the environment, and human health. This study focused on the ecological risk assessment of pesticide use in rice farming using the PRIMET model as a decision support tool to evaluate the risks of pesticide exposure, ecotoxicity, and risk characterization, as well as employing the species sensitivity distribution (SSD) assessment model to calculate the potentially affected fraction (PAF) of species based on the computed predicted environmental concentrations (PECs) from PRIMET.

4. 3. The Effect of Temperature Gradients During Intercritical Annealing of Advanced High Strength Steels : Method Development for Experimental Streamlining

   University essay from KTH/Materialvetenskap

   Author : Helena Ek Jendrny; [2023]
   Keywords : AHSS; Gleeble; Intercritical annealing; Retained austenite; Medium Mn Steel; AHSS; Gleeble; interkritisk glödgning; austenit; Medium Mn stål;

   Abstract : The third-generation advanced high strength steels, AHSS, represent an opportunity for today’s steel development, where lighter materials with maintained strength and toughness are in demand. The unique properties of these materials often stem from a tailored microstructure. READ MORE

5. 4. Mechanistic Model Development for a Multi-Enzyme Protein Hydrolysis Process

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Tito Nilsson; [2023]
   Keywords : Mechanistic Model; Enzyme; Hydrolysis; Chemical Engineering; Technology and Engineering;

   Abstract : New food products are constantly put on the market. Today the focus often lies in creating nutritional and sustainable products to reduce the environmental impact of the product in question. One example of this is the approval of the yellow mealworm, Tenebrio Molitor, as a novel food in the European union. READ MORE

6. 5. Probing the Structure of Ionised ISM in Lyman-Continuum-Leaking Green Pea Galaxies with MUSE

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Chinmaya Nagar; [2023]
   Keywords : Emission-line ratio; Gaussian convolution; Green pea galaxies; ISM; Ionised ISM; Lyman continuum LyC ; Low-Redshift Lyman Continuum Survey LzLCS ; Lyman continuum emitter LCE ; LyC escape; LyC escape fraction; MUSE; MPDAF; Voronoi binning;

   Abstract : Lyman continuum (LyC) photons are known to be responsible for reionising the universe after the end of the Dark Ages, which marked a period called the Epoch of Reionisation (EoR). While these high-energy photons are thought to predominantly originate from young, hot, massive stars within the earliest galaxies, and contributions from high-energy sources like quasars and AGN, the origins of these photons are yet not well known and highly debated.
