1. Biot’s respiration named after Camille Biot is an abnormal ataxic breathing pattern, where rapid series of shallow respiration are followed by a period of apnea. In order to known how AMP kinase, knock down leads to Biot respiration in mice; it is necessary to known how AMP kinase affects respiratory rate. AMP kinase is a metabolic sensor and is activated in response to stretching of the lung alveolar cells and other stressors. During respiration, the lung goes through cycles of expansion and contraction (Budinger et al., 2008). When the alveolar cells stretch during expansion, the 5′ AMP-activated ...

55 Gallon Plastic Drum 55 Gallon Plastic Drum 55 gallon plastic drums are conveniently used in industry and agriculture. Therefore, the used or worn out drums can be recycled, and the quantity of the plastic feedstock is significant. Recycling has several aspects of the environmental impact. Firstly, when the used drum is recycled, it is not stored at the landfill sites, and thus no water or land pollution takes place. Secondly, it becomes a secondary resource, and therefore less primary resources are used. Thirdly, the environmental impact of the recycling process should be taken into the account: if recycling ...
