Scalar Perturbations of Charged Dilaton Black Holes

We have studied the scalar perturbation of static charged dilaton black holes in 3+1 dimensions. The black hole considered here is a solution to the low-energy string theory in 3+1 dimensions. The quasinormal modes for the scalar perturbations are calculated using the third order WKB method. The dilaton coupling constant has a considerable effect on the values of quasi normal modes. It is also observed that there is a linear relation between the quasi normal modes and the temperature for large black holes.Comment: 14 pages, 13 figures, typos correcte

A Critical History of Colonization and Amerindian Resistance in Trans-Appalachia 1750-1830: The Proclamation Wars

A careful examination of events in Colonial Trans-Appalachia the region geographically encompassed by territories west of the Appalachian Mountain Range and east of the Mississippi River at the time of the French and Indian War facilitates analysis of regime formation amongst Amerindian and European Colonists. This thesis examines the effects of contact on Amerindian and European polities in a form that seeks relevance to contemporary issues. It draws on historical timelines that immediately pre and post-date the French and Indian War. It argues how distinctive decision making structures used by Amerindian and European societies provide preliminary models for understanding how their respective forms of sociopolitical organization conditioned political relationships

The Pauline Understanding of The Law of Christ

It is puzzling, then, to hear Paul affirming the validity of the law, as he does in his letter to the Romans (3:21,31; 7:12,16) and in the first letter to the Corinthians (14:34). It seems to be a contradiction in terms when Paul combines law and Christ in the expression the law of Christ (Gal. 6:2). The purpose of this study is to find out what Paul means by this phrase and those phrases which are similar (1 Cor. 9:21; Rom. 3:27; 8:2), in view of his teaching on law and the revelation given in Christ

The Widening Research Gap • lll Forestry

I have become increasingly concerned in recent years about the proliferation of forestry problems in relation to the rate of production of new knowledge required to solve them. New techniques like balloon logging and remote sensing add to opportunities to practice forestry, while new constraints imposed by such national concerns as pesticides and environmental health complicate its practice. Competition for land use by a society now dominately motivated by urbanized values adds new social and economic dimensions. Consequences of poor management decisions are more far-reaching and more drastic than ever before

Making it Real: ALANA Teacher Education Preparation, Communication and Diversity Suppositions

This article clarifies brisk salient education and communication perspectives on the need for and role of ALANA (African, Latino, Asian and Native American) teachers and teacher education students in the nation. From the co-authors’ perspectives as African American professors of prospective ALANA K-12 teachers, the notion of “Making it Real: ALANA Teacher Education Preparation, Communication and Diversity Suppositions” is an aerial design that continues to be drafted. This design must be multicultural, multiethnic, multimedia and multi-disciplined in order to be fecund. The creation of a video by ALANA university teacher education students also demonstrated that diversity is invaluable and central to the teacher education process. The experiences and cultural lenses of ALANA teachers in training are seen as being equally valuable in measuring teaching and learning. Albert Bandura’s Social Cognitive Theory (social learning theory) provides the theoretical underpinning for this article

Absolute Timing of the Crab Pulsar with RXTE

We have monitored the phase of the main X-ray pulse of the Crab pulsar with the Rossi X-ray Timing Explorer (RXTE) for almost eight years, since the start of the mission in January 1996. The absolute time of RXTE's clock is sufficiently accurate to allow this phase to be compared directly with the radio profile. Our monitoring observations of the pulsar took place bi-weekly (during the periods when it was at least 30 degrees from the Sun) and we correlated the data with radio timing ephemerides derived from observations made at Jodrell Bank. We have determined the phase of the X-ray main pulse for each observation with a typical error in the individual data points of 50 us. The total ensemble is consistent with a phase that is constant over the monitoring period, with the X-ray pulse leading the radio pulse by 0.0102+/-0.0012 period in phase, or 344+/-40 us in time. The error estimate is dominated by a systematic error of 40 us in the radio data, arising from uncertainties in the variable amount of pulse delay due to interstellar scattering and instrumental calibration. The statistical error is 0.00015 period, or 5 us. The separation of the main pulse and interpulse appears to be unchanging at time scales of a year or less, with an average value of 0.4001+/-0.0002 period. There is no apparent variation in these values with energy over the 2-30 keV range. The lag between the radio and X-ray pulses may be constant in phase (rotational) or constant in time (linear pathlength). We are not (yet) able to distinguish between these two interpretations.Comment: 11 pages, 2 figure

A METHOD FOR ASSESSING BLACKBIRD DAMAGE TO RIPENING RICE

A method for measuring and mapping the location of blackbird (Icterinae) damage to ripening rice over time was developed and employed in 7 commercial rice fields ranging from 20.6 to 47.4 ha in Matagorda County, Texas, during the 1985 and 1986 growing seasons. Ten evenly-spaced transects were established perpendicular to the longest side of the field and each transect was sampled at pre-determined distances. Transects were subdivided into edge (\u3c= 60 m from field border) and middle (\u3e 60 m from the field border) strata. The measured percent damage was compared to visual estimates for 3 samplings to assess the accuracy and precision of the latter. Measuring the percent damage to individual panicles appears to be valid, but damage may be underestimated. This sampling method may be useful for assessing the efficacy of current and proposed damage control techniques. Visual estimates were too high at low (\u3c 5%) damage levels and too low at higher (\u3e 5%) levels compared to measured damage
