Gene Expression Analysis of Oat Phytases During Malting Using RT-qPCR

Oat grains contain high levels of phytic acid, an anti-nutritional compound that reduces nutrient bioavailability, along with notably low phytase activity, the enzymatic mechanism responsible for phytic acid degradation. Malting of oats prior to human consumption is a recognized method to reduce phytic acid content by inducing phytase expression, thereby enhancing the nutritional value of oats. Th

The interaction between the Gbetagamma dimer and AQP2

En av de viktigaste molekylerna för levande organismer är vatten, och det är ingen slump att det är just vatten som efterlyses när astronomer letar efter planeter som kan innehålla liv. En sådan viktig molekyl måste kunna transporteras in och ut ur våra celler på ett pålitligt sätt. Detta görs av proteiner som fungerar som kanaler för vatten i våra cellmembran: så kallade aquaporiner. Det finns måAquaporin 2 (AQP2) is a membrane channel protein that is in humans most importantly found at the end of the renal collecting duct. A lack of AQP2 in the apical membrane can lead to diabetes insipidus (DI), characterized by dehydration and dilute urine, making protein-protein interactions between AQP2 and other proteins an important field of study. In this study, the interaction between an AQP2 con

Financial Crises and Recovery Trajectories: A Comparative Panel Study of Crisis Types and Recovery Dynamics

This paper examines the economic consequences of financial crises and the determinants of recovery duration through a structural-institutionalist perspective. Drawing on cross-country data from 160 countries (1950–2019) and using updated classifications of crisis episodes, it explores two central questions: how do different types of crises affect GDP per capita? and what factors explain variation

The study was guided by the Technology Acceptance Model 2, Self-Determination Theory, and Flow Theory. Results showed that gamif

BEV-Based Multi-Camera Detection for Sports Player Localization

Kan spelardetektion på en plan förbättras genom att öka antalet kameror som används för detektionen? Med utvecklingen av artificiell intelligens (AI) och maskininlärning har möjligheterna inom en rad områden ökat markant, exempelvis sportteknologi. Där används AI för att automatiskt detektera spelare på en plan med hjälp av kamerabilder. I det här arbetet undersöks hur en AI-modell kan förbättra dAccurate detection of player positions is essential for sports analysis. Traditional single-camera methods generally suffer from occlusion and diminishing resolution far away. This work proposes using multi-camera Bird's Eye View (BEV) detection to overcome these issues. Synthetically generated data was used to train and test the detection model, which uses images from six cameras placed aroun

SONIQO-16

This project explores how a beginner friendly music production device can lower the threshold for engaging with sound creation and rhythm making.
