Area of Science:
- Environmental Science
- Biotechnology
- Agricultural Engineering
Background:
- Global increase in swine farming generates substantial wastewater rich in ammonia and nutrients.
- Swine wastewater poses significant eutrophication risks and environmental challenges.
- Conventional treatment methods struggle with high ammonia and oxygen demand in swine effluent.
Purpose of the Study:
- To review conventional swine wastewater treatment methods.
- To explore microalgae-based phytoremediation for swine wastewater.
- To discuss the advantages, limitations, and future of microalgal treatment.
Main Methods:
- Literature review of conventional and microalgae-based wastewater treatment.
- Analysis of microalgal tolerance and nutrient removal capabilities.
- Discussion of process efficiency and scalability.
Main Results:

515
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

17.7K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

6.9K
Electrical current is defined as the rate at which charge flows. When there is a large current present, such as that used to run a refrigerator, a large amount of charge moves through the wire in a small amount of time. If the current is small, such as that used to operate a handheld calculator, a small amount of charge moves through the circuit over a long period of time. The SI unit for current is the ampere (A), named for the French physicist André-Marie Ampère (1775–1836).

00:56Extraction: Advanced Methods
1.1K
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...
