Land use and pollution patterns on the Great Lakes

The author has identified the following significant results. The final mapping of the large watersheds of the Manitowoc and the Oconto was done using the 25% sampling approach. Comparisons were made with earlier strip mapping efforts of the Oconto and Manitowoc watersheds. Regional differences were noted. Strip mapping of the Oconto resulted in overestimation of the amount of agricultural land compared to the random sampling method. For the Manitowoc, the strip mapping approach produced a slight underestimate of agricultural land, and an overestimate of the forest category

BASE REVENUE PROTECTION AND REVENUE COUNTERCYCLICAL PROGRAMS FOR SPRING WHEAT IN NORTH DAKOTA

The National Corn Growers Association Public Policy Team’s Base Revenue Projection Program (BRP) and the Revenue Countercyclical Program (RCCP) were analyzed. The analysis was done for spring wheat using the BRP-RCCP calculator, as developed by the National Corn Growers Association. Three representative counties (Hettinger, Ward and Cavalier) were chosen in North Dakota. Historic and projected data were used to analyze 2002 to 2010 crop years. A comparison of the BRP-RCCP programs to the current farm program was done. From 2002 to 2005, Ward County would have received nearly identical payments under the BRP-RCCP program and the current farm program. The Hettinger County farm would have received considerably more under the BRP-RCCP program - $76.87 per acre, compared with$38.99 under the existing farm program. This amounts to $9.22 per acre per year. For the Cavalier County farm, the advantage to the BRP-RCCP program was only$7.56 per acre for the four-year period.farm bill, wheat, countercyclical payments, revenue, Agricultural Finance, Crop Production/Industries,

BASE REVENUE PROTECTION AND REVENUE COUNTERCYCLICAL PROGRAMS FOR SOYBEANS IN NORTH DAKOTA

The National Corn Growers Association Public Policy Team’s Base Revenue Projection Program (BRP) and the Revenue Countercyclical Program (RCCP) were analyzed. The analysis was done for soybeans using the BRP-RCCP calculator, as developed by the National Corn Growers Association. Three representative counties (Cass, Stutsman and Benson) were chosen in North Dakota. Historic and projected data were used to analyze 2002 to 2010 crop years. A comparison of the BRP-RCCP programs to the current farm program was done. From 2002 to 2005, all counties would have received more payments with the BRP-RCCP program than they would have received under the current farm program. Benson County would benefit the most from this program, receiving $58.56 per acre more during the four years, or$14.64 per year. Cass County would receive $33.35 per acre and Stutsman County would receive$16.20 per acre more during this four-year period.farm bill, soybeans, countercyclical payments, revenue, Agricultural Finance, Crop Production/Industries,

BASE REVENUE PROTECTION AND REVENUE COUNTERCYCLICAL PROGRAMS FOR CORN IN NORTH DAKOTA

The National Corn Growers Association Public Policy Team’s Base Revenue Projection Program (BRP) and the Revenue Countercyclical Program (RCCP) were analyzed. The analysis was done for corn using the BRP-RCCP calculator, as developed by the National Corn Growers Association. Three representative counties (Richland, Barnes and Foster) were chosen in North Dakota. Historic and projected data were used to analyze 2002 to 2010 crop years. A comparison of the BRP-RCCP programs to the current farm program was done. For 2002 to 2005, Barnes County would have received more total payments under the BRP-RCCP program than with the current farm program. The gain would have been $24.12 per acre during the four years. Richland and Foster counties would have received more payments with the current farm program than with the BRP-RCCP program. The Richland County farm would have received considerably more under the existing program -$78.03 per acre for the four-year period, or about $19.50 per acre per year. For Foster County, the advantage to the current program was only$10.05 for the four-year period.farm bill, corn, countercyclical payments, revenue, Agricultural Finance, Crop Production/Industries,

Skylab imagery: Application to reservoir management in New England

The author has identified the following significant results. S190B imagery is superior to the LANDSAT imagery for land use mapping and is as useful for level 1 and 2 land use mapping as the RB-57/RC8 high altitude imagery. Detailed land use mapping at levels 3 and finer from satellite imagery requires better resolution. For evaluating factors that are required to determine volume runoff potentials in a watershed, the S190B imagery was found to be as useful as the RB-57/RC8 high altitude aircraft imagery

Arctic and subarctic environmental analyses utilizing ERTS-1 imagery

The author has identified the following significant results. ERTS-1 imagery provides a means of distinguishing and monitoring estuarine surface water circulation patterns and changes in the relative sediment load of discharging rivers on a regional basis. Physical boundaries mapped from ERTS-1 imagery in combination with ground truth obtained from existing small scale maps and other sources resulted in improved and more detailed maps of permafrost terrain and vegetation for the same area. Snowpack cover within a research watershed has been analyzed and compared to ground data. Large river icings along the proposed Alaska pipeline route from Prudhoe Bay to the Brooks Range have been monitored. Sea ice deformation and drift northeast of Point Barrow, Alaska have been measured during a four day period in March and shore-fast ice accumulation and ablation along the west coast of Alaska have been mapped for the spring and early summer seasons

Two-stage dissipation in a superconducting microbridge: Experiment and modeling

Using fluorescent microthermal imaging we have investigated the origin of "two-step" behavior in I-V curves for a current-carrying YBa_2Cu_3O_x superconducting bridge. High resolution temperature maps reveal that as the applied current increases the first step in the voltage corresponds to local dissipation (hot spot), whereas the second step is associated with onset of global dissipation throughout the entire bridge. A quantitative explanation of the experimental results is provided by a simple model for an inhomogeneous superconductor, assuming that the hot spot nucleates at a location with slightly depressed superconducting properties.Comment: 4 pages, 4 figure

HPV prevalence and concordance in the cervix and oral cavity of pregnant women.

OBJECTIVES: This investigation examined human papillomavirus (HPV) in pregnant women in order to characterize viral prevalence, types and concordance between infection in the cervix and in the oral cavity. METHODS: A total of 577 pregnant women seeking routine obstetric care were evaluated for HPV infection in their cervix during gestation and immediately before delivery, and in the oral cavity during gestation. Male partners present during the gestational clinic visit also provided a specimen from their oral cavity. HPV assessment was performed by PCR, dot blot hybridization and DNA sequencing. A sexual and health questionnaire was completed by the pregnant women. RESULTS: HPV prevalence in women was 29% in the cervix and 2.4% in the oral cavity. Among those with both gestational and delivery specimens, 35% were infected at least once and 20% had infection at both intervals. At delivery, 68% of infected women had an oncogenic HPV type in the cervix. There was no type-specific HPV concordance between the two cervical specimens, nor cervical and oral results in women, nor with cervical and oral findings between partners. CONCLUSION: The lack of association in HPV positivity and types between the cervix and oral cavity in these women suggests that self-inoculation is uncommon. This source of infection does not appear to be from oral contact with a current male partner, since there also was no concordance between partners. These results suggest either other modes of HPV transmission or differences in susceptibility to HPV infection or its clearance in the oral cavity and genital mucosa
