11. Assessing the toxic impact of chemicals using bacteria
Sammanfattning : There is a considerable backlog in the testing of new chemical compounds for their ecotoxic properties, mostly due to the lack of appropriate testing methods. In addition, there is a vivid debate today about the test endpoint for many of the existing methods. LÄS MER
12. The Alzheimer Aβ Peptide : Identification of Properties Distinctive for Toxic Prefibrillar Species
Sammanfattning : Proteins must have specific conformations to function correctly inside cells. However, sometimes they adopt the wrong conformation, causing dysfunction and disease. A number of amyloid diseases are caused by misfolded proteins that form amyloid fibrils. One such disease is Alzheimer’s disease (AD). LÄS MER
13. Effects of toxin-producing phytoplankton on copepods: feeding, reproduction and implications to the fate of toxins
Sammanfattning : Phytoplankton growth and loss rates are governed by several factors and in many cases, when growth control fails, algal blooms are established. Such blooms can be formed by different phytoplankton species and some of them have harmful impacts on marine ecosystems. LÄS MER
14. Media Influence on Pollution, and Gender Equality

15. Studies to Avoid Decreased Efficiency in Multiple Stage Biological Wastewater Treatment Plants: Concerning Forests Industry Effluents
Sammanfattning : Målet med den här studien är att förhindra effektivitetssänkningar i moderna biologiska reningsanläggningar för skogsindustriella avloppsvatten. Biologiska processer är vanligtvis effektiva när det gäller att reducera lättnedbrytbart organiskt material. Eftersom den utgörs av levande mikroorganismer (MO) är tekniken känslig. LÄS MER
