Affordable Analog OxygenMonitor forMaintaining Safe Oxygen Concentration in IndustrialEnvironments

Safe climate policy is affordable—12 reasons

There is a widespread sense that a sufficiently stringent climate mitigation policy, that is, a considerable reduction of greenhouse gas emissions to avoid extreme climate change, will come with very high economic costs for society. This is supported by many cost–benefit analyses (CBA) and policy cost assessments of climate policy. All of these, nevertheless, are based on debatable assumptions....

Safe Climate Policy is Affordable – 14 Reasons

There is a widespread sentiment that a sufficiently stringent climate policy, i.e. considerable reduction of greenhouse gas emissions to avoid extreme climate change, will go along with tremendous economic costs for society. Various climate cost-benefit analyses and climate policy cost assessments have calculated these costs, but all of them are characterized by debatable assumptions. Moreover,...

Measuring Dissolved Oxygen Concentration in Aquaculture

(DO) is considered the most important water quality variable in fish culture. In the broadest sense, however, dissolved oxygen concentration is no more important than other environmental variables because any factor that is outside the range tolerated by fish can cause stress or death. What makes dissolved oxygen concentration so important in intensive fish culture is the speed with which it ca...

Oxygen Concentration in Isolated Chloroplasts during Photosynthesis.

The O(2) concentration in intact and osmotically disrupted isolated spinach (Spinacia oleracea, L.) chloroplasts during photosynthesis was estimated. The chloroplasts were allowed to reduce 3-phosphoglycerate, CO(2), or ferricyanide in light until the rate of O(2) production was linear. When the light was turned off O(2) evolution from the chloroplasts continued for a few seconds. This prolonge...
