Extraction and Quantification of Hydrolyzable Tannins in Acorns from Different Species of Oak Trees (Quercus spp.)

Do white-tailed deer (Odocoileus virginianus) prefer to eat certain types of acorns based on tannin content? Hydrolyzable tannins consist of gallate groups connected via ester linkages to a carbohydrate (D-glucose) The Prussian Blue method was used to determine hydrolyzable tannin conten

Contributions of divergent and nondivergent winds to the kinetic energy balance of a severe storm environment

Divergent and rotational components of the synoptic scale kinetic energy balance are presented using rawinsonde data at 3 and 6 h intervals from the Atmospheric Variability Experiment (AVE 4). Two intense thunderstorm complexes occurred during the period. Energy budgets are described for the entire computational region and for limited volumes that enclose and move with the convection. Although small in magnitude, the divergent wind component played an important role in the cross contour generation and horizontal flux divergence of kinetic energy. The importance of V sub D appears directly to the presence and intensity of convection within the area. Although K sub D usually comprised less than 10 percent of the total kinetic energy content within the storm environment, as much as 87 percent of the total horizontal flux divergence and 68 percent of the total cross contour generation was due to the divergent component in the upper atmosphere. Generation of kinetic energy by the divergent component appears to be a major factor in the creation of an upper level wind maximum on the poleward side of one of the complexes. A random error analysis is presented to assess confidence limits in the various energy parameters

The Madisonian Standard for Conceptualizing American Citizenship

American political development was fashioned by a social contract. More specifically, the American republic evolved through the Madisonian social contract, an agreement premised on James Madison’s intention that deliberative citizenship would collaborate with decentralized government in order to advance the public good. This paper identifies the problem with the Madisonian contract today, that the relationship between citizens and government, or rather, Congress, is one that is infused with antagonism and a record high level of distrust. This present-day characterization of the broken relationship between citizens and Congress is symptomatic of a deteriorated Madisonian contract. Public opinion polls cast the illusion that a broken Congress is responsible for the deterioration of Madison’s contract. However, through an assessment of polling data along with an examination of the exceptional nature of citizenship in America, this paper reasons that the dwindling of the Madisonian contract is due to a decline in thick deliberative citizenship. In addition to diagnosing the current state of Madison’s contract, this paper compares remedies to cure the problem of a thinly engaged citizenry in the hope to rewrite the terms of the Madisonian contract within the contours of American political development
