the optimum operational range of the blower, the operational range of dissolved oxygen content in a biological reaction tank, and the minimum required value of dissolved oxygen content; and a control unit for controlling the blow amount of the blower according to both the optimum operational ...
Since the 1960s the amount of fertiliser used by farmers has increased sixfold, and not all of that extra nitrogen ends up in their crops. Maize, in particular, is described by experts in the field as a “nitrogen-leaky” plant because it has shallow roots and takes up nitrogen for ...

For each data set, results are normalized to the amount of energy used to load the document in native mode. Fig. 5. Normalized energy used to load presentations size. Figure 3 shows the sizes of these documents, as well as the reductions achieved by distillation. As might be expected, ...
keeping Earth's climate warm and habitable. Without this process, Earth could notsustainlife. However, the "man-made" greenhouse effect has now become a big problem. When people produce huge amounts of extra greenhouse gases by ...
coonony and reducing the preenhouse gas emissions required to get food from its origin to your plate. Buying fresh food means reducing packaging and energy used for processing. Eating organic meal and vegetables keeps farm chemicals off your plate, as well as out of rivers and streams.___ ,...
Together, they form the world's largest clean energy corridor, expected to generate 300 billion kilowatt-hours of clean electricity annually. This amount can meet the annual electricity demand of 360 million people, equivalent to a quarter of China's population. Wang Zhilin, the former director ...
such as arsenate(V), chromate(VI), selenate and uranium(VI). In several prokaryotes, even the electron donor may be inorganic, which results in purely inorganic (lithotrophic) redox reactions for energy conservation under anoxic conditions; notable examples are the oxidation of sulfur species with...
Malaysia has seen massive economic development and urbanization accompanied by increasing greenhouse gas emissions. It was crucial for us to select a highly efficient technology, like GE’s 9HA.01, to help reduce the amount of fuel used to generate electricity. ...
Climate stabilization requires the mobilization of substantial investments in low- and zero-carbon technologies, especially in emerging and developing economies. However, access to stable and affordable finance varies dramatically across countries. Models used to evaluate the energy transition do not differen...
