Abstract Marked enlargement of the mitochondrial compartment is present in heart muscle, liver, and erythroblasts of iron- and copper-deficient rats. Mitochondria are increased in size, and may also be increased in number, particularly in heart muscle and erythroid cells. The enlarged mitochondria are more electron-lucent and in the hepatocyte may have sparser packing of cristae than in animals on a complete diet. Morphologic changes in the erythroid percursors of three iron-deficient patients are similar to those observed in the experimental animal. The morphologic response is not attributable to anemia or inanition but appears more specifically related to the lack of trace metals or cofactors required for the synthesis of certain mitochondrial enzymes.

Antecedent topography is an important aspect of coastal morphology when studying and forecasting coastal change hazards. The uncertainty in morphologic response of storm-impact models and their use in short-term hazard forecasting and decadal forecasting is important to account for when considering a coupled model framework. This study provided a methodology to investigate uncertainty of profile response within the storm impact model XBeach related to varying antecedent topographies. A parameterized island Gaussian fit (PIGF) model generated an idealized baseline profile and a suite of idealized profiles that vary specific characteristics based on collated observed LiDAR data from Dauphin Island, AL, USA. Six synthetic storm scenarios were simulated on each of the idealized profiles with XBeach in both 1- and 2-dimensional setups and analyzed to determine the morphological response and uncertainty related to the varied antecedent topographies. Profile morphologic response tends to scale with storm magnitude but among the varied profiles there is greater uncertainty in profile response to the medium range storm scenarios than to the low and high magnitude storm scenarios. XBeach can be highly sensitive to morphologic thresholds, both antecedent and time-varying, especially with regards to beach slope.

This paper describes numerical modeling of long-term evolution of inlet systems in southwest and central Florida. The paper discusses a general methodology developed following four case studies and application to the case study of Gordon Pass in southwest Florida. The case study of Gordon Pass demonstrates the importance of considering large temporal and spatial scales in evaluating morphologic response to inlet management practices. The results describe the evolution of Gordon Pass from 1930 to present. The analysis begins with natural conditions that existed before dredging or inlet modifications and investigates how inlet evolution can be influenced by navigation improvements and provide tools to evaluate alternatives.
