The Use of AIS Data for Identifying and Mapping Calcareous Soils in Western Nebraska
The identification of calcareous soils, through unique spectral responses of the vegetation to the chemical nature of calcareous soils, can improve the accuracy of delineating the boundaries of soil mapping units over conventional field techniques. The objective of this experiment is to evaluate the use of the Airborne Imaging Spectrometer (AIS) in the identification and delineation of calcareous soils in the western Sandhills of Nebraska. Based upon statistical differences found in separating the spectral curves below 1.3 microns, calcareous and non-calcareous soils may be identified by differences in species of vegetation. Additional work is needed to identify biogeochemical differences between the two soils
Front Material of Crossed Swords: Entanglements between Church and State in America
The purpose of this study is to identify and assess a number of political, economic, and religious factors that have defined and redefined the historical accommodation between church and state. Particular attention is given to the effects of fiscal, educational, and social regulations on the free exercise of religion.
Religious liberty in America is commonly thought to be secured by a constitutional wall of separation between church and state. Its character is best understood in the context of an original Protestant Christian cultural consensus which underlay the plurality of competing sects. The findings of this study are that, first, American law and custom still preserve elements of an earlier state church tradition despite the historical coincidence between the framing of the Constitution and the disestablishment of religion. The political and religious perspective of the founders is in fact so strongly impressed upon the constitutional system that, second, discrepancies between the basic doctrines of Christianity and the expectations of diverse religious and secular subcultures are among the major sources of conflict within the political arena. But, third, changing interpretations of the constitutional provisions respecting religion and a growing state presence in all areas of social and economic life tend to reduce the formal role of religion in public life, leading some religious leaders to express public concern over losses of liberty and influence by the church. Current litigation indicates that churches are faced with unaccustomed restrictions on the corporate powers, tax immunities, internal operations, teaching ministries, and missionary activities of their organizations.
This study analyzes the relationship of church and state in America against the background of early Christianity, the emergence of nationalism in Europe, the settlement of America, and the framing of the Constitution. Its central feature is a chronological and topical study of the Supreme Court rulings on religious issues
Electron energy analyzer
Electrostatic deflection analyzer with three spherically concentric grids allows production of electrons within a small volume at the center of the inner sphere. By applying a retarding potential between the middle and inner spheres, the energies of the electrons can be measured
Competitive effects between stationary chemical reaction centres: a theory based on off-center monopoles.
The subject of this paper is competitive effects between multiple reaction sinks. A theory based on off-center monopoles is developed for the steady-state diffusion equation and for the convection-diffusion equation with a constant flow field. The dipolar approximation for the diffusion equation with two equal reaction centres is compared with the exact solution. The former turns out to be remarkably accurate, even for two touching spheres. Numerical evidence is presented to show that the same holds for larger clusters (with more than two spheres). The theory is extended to the convection-diffusion equation with a constant flow field. As one increases the convective velocity, the competitive effects between the reactive centres gradually become less significant. This is demonstrated for a number of cluster configurations. At high flow velocities, the current methodology breaks down. Fixing this problem will be the subject of future research. The current method is useful as an easy-to-use tool for the calibration of other more complicated models in mass and/or heat transfer
Enabling access to effective mentor support: evaluation of mentoring modules to inform blended learning design
With the drive for professionalisation of the workforce and 30 hours CPD, time issues are coming evermore to the fore. Using technology to maximise productivity within the time constraints, more and more institutions are turning on e-learning. However, it is also recognised that e-learning is not necessarily the most appropriate way for effective learning to occur and that blended models might be better
Enabling access to effective mentor support: ITT mentoring support available across a range of work-based learning providers
The research explores the nature of six small work-based learning providers
in London and contrasts them to further education colleges. It identifies the
complexities of the sector and the issues facing providers in supporting their
own staff who need mentoring as part of their initial teacher training
