As the global demand for petroleum-based plastics continues to increase, unstable crude oil price and related environmental problems have triggered a search for replacing these non-biodegradable and unsustainable plastics.
Global energy infrastructure is becoming increasing unstable, compromising security of supply.
Dominance hierarchies of three-spined stickleback (Gasterosteus aculeatus) shoals became increasing unstable as flow rate increased (simulating spate conditions) or water levels decreased (simulating drought) (Sneddon et al. 2006).
In a study done to determine the levels of serum resistin between patients with stable and unstable angina it was found that plasma concentrations of resistin were significantly increased in unstable angina group in comparison with stable angina group and control groups.
Once the marine sector began an unstable retreat, as has occurred for the West Antarctic ice sheet, the likelihood of rapid mass loss increased under unstable bedrock configurations, partially due to the sensitivity to oceanic conditions19,20,50,54,55.
They found that hoarding increased in unstable times — during the Second Punic War in the third century B.C., for example.
Circulating RANTES level is elevated in symptomatic coronary artery disease [33] and is also acutely increased in unstable angina pectoris during severe ischemic symptoms [34].
It is known that the onset of acute coronary syndromes is associated with changes in the inflammatory response in these lesions, including a shift in phenotype of intraplaque T cells: the frequency of activated T lymphocytes is significantly increased in unstable lesions [5], [21].
7 TNF-α production is increased in unstable atherosclerotic plaques 8 and is detectable in increased concentrations in patients with acute myocardial infarction (AMI).
These fluctuations can be attributed to several factors including population increase, unstable government policies, youth restiveness in regions of oil exploration and international market dynamics.
