Abstract. Heat stress due to increased temperature is an agricultural problem in many areas in the world. Transitory or constantly high temperatures cause an array of morpho-anatomical, physiological and biochemical changes in plants, which affect plant growth and development and may lead to a drastic reduction in economic yield.
سؤال
Here we highlight four key areas for improving our approach towards understanding plant heat stress responses. First, although the term 'heat stress' is broadly used, that term encompasses heat shock, heat wave and warming experiments, which vary in the duration and magnitude of temperature increase imposed. A greater integration of results and
سؤال32;A high heat rate and low efficiency could mean your power plant isn’t dispatched to the market by a grid operator. To calculate the thermal efficiency of a power plant divide 3,412 BTU by the heat rate. For instance, if a coal power plant has a heat rate of 10,000 BTU/kWh, its thermal efficiency would be 3,412 BTU / 10,000 BTU/kWh or 34%.
