Five neural nets relate macro-economic input variables to macro-economic output variables. Three nets for the United States (US) and two nets for the Japanese economy were computed to model the production systems of the two most advanced economies in the world. When the Japanese input vector was used through a US net, gross domestic product (GDP), and GDP per capita, and GDP per person employed are reduced in the same order, -0.38, -0.37, and -0.39% per year. Similarly, when the US input vector is passed through the Japanese neural net each of the three measures of gross domestic product drops in the same order -0.22, -0.22 and -0.23% per year. All of the 20 output measurements used in the analysis have similar results when an alien input vector is used. The model presumes that the determinants of growth are implicit in the neural net (black box), and that the determinants of growth have been culturally shaped through adaptation to the norms and values reflected in the input vectors. A neural net could not be obtained using inputs from all G7 nations as a single group. Convergence of predicted outputs with observed outputs required the use of same-nation data in the iterations.

Each soil series was placed into one of three categories; suited for traditional leach fields or mound systems, suited for mound systems only, or not suited for soil-based treatment. In a mound system, a layer of sand is placed on top of the natural soil to augment its treatment capacity. Statewide only 6.4% of the land area is suited for soil absorption systems using traditional leach lines. This amounts to 1,680,020 acres of land. Soil series suited for mound systems are present in 25.4% of Ohio's land area accounting for 6,667,579 acres of land.

To do this, we isolated pharynxes from embryos of stage 13 to stage 15, the period during which evagination is occurring, and measured the amount of pharyngeal floor area occupied by thyroid, using the raised ridge at its periphery to define its limits. These measurements were then compared with volumetric ones of the same thyroids. Additionally, living isolated pharynxes were treated with dihydrocytochalasin B, a compound known to disrupt actin filaments. The results showed that growth of the thyroid (as indicated by its volume) is not accompanied by expansion of the primordium into the surrounding pharyngeal space (as indicated by its area). In addition, treatment with dihydrocytochalasin B caused flattening and spreading of the raised ridge of cells that bounds the thyroid pit suggesting that microfilaments are involved in maintenance of this structure. A discussion of the results in relation to previously reported findings implicates microfilaments in both the formation and maintenance of the peripheral cell ridge.

The United States has agreed to join with the international community in reducing its greenhouse gas emissions to 7% below 1990 levels. To aid in this goal a Geographic Information System (GIS) based deterministic model was created to assess the potential impact of different land-use strategies for mitigating Ohio's carbon dioxide (CO2) emissions and lowering its total CO2 budget. CO2 was chosen as the greenhouse gas of focus for this study because it has been identified as a significant greenhouse gas impacting the climate and it is the only greenhouse gas capable of being anthropogenically sequestered from the atmosphere.
