Non-contact temperature measurement of a falling drop

The 105 meter drop tube at NASA-Marshall has been used in a number of experiments to determine the effects of containerless, microgravity processing on the undercooling and solidification behavior of metals and alloys. These experiments have been limited, however, because direct temperature measurement of the falling drops has not been available. Undercooling and nucleation temperatures are calculated from thermophysical properties based on droplet cooling models. In most cases these properties are not well known, particularly in the undercooled state. This results in a large amount of uncertainty in the determination of nucleation temperatures. If temperature measurement can be accomplished then the thermal history of the drops could be well documented. This would lead to a better understanding of the thermophysical and thermal radiative properties of undercooled melts. An effort to measure the temperature of a falling drop is under way. The technique uses two color pyrometry and high speed data acquisition. The approach is presented along with some preliminary data from drop tube experiments. The results from droplet cooling models is compared with noncontact temperature measurements

Property

Covers cases on easements by implied reservations, on condemnation of public property, on proof of intent to claim adversely (Powell), on the validity of antenuptial agreements that alter the status of property acquired after the marriage (Power), and on the extent of the duty to rebuild under a lease with a convenant to rebuild (Robinson)

A number or a person?: perspectives on credit scoring and fair mortgage lending: article four in a five-part series

This fourth article in a five-part series on credit scoring showcases three different perspectives. Up for debate is how lenders can ensure fair treatment to all mortgage applicants and how consumers can be educated about the effect their credit score has on loan pricing.Mortgage loans

School Choice Vouchers and Special Education in Indiana Catholic Diocesan Schools

Catholic schools are now located at a crossroads of school choice voucher programs and special education services. With enrollment in Catholic schools declining over the past several decades, voucher programs that allow parents to use public funds for tuition at private schools – including tuition for students with disabilities – could possibly help to steady or even reverse this decline. This study examined the impact of Indiana’s statewide voucher program on Catholic schools, student enrollment, and special education services in three large diocesan school systems. The findings address issues related to enrollment growth, changing student population characteristics, special education services, and the professional development needs of teachers in these schools. The authors discuss the implications of the voucher program for the enrollment and education of students with disabilities in Catholic schools. Los cupones para escuelas de elección y la educación especial en las escuelas de la diócesis católica de Indiana Las escuelas católicas se encuentran en una encrucijada entre los programas de cupones para escuelas de elección y los servicios de educación especial. Al disminuir las matrículas en las escuelas católicas en las últimas décadas, los programas de cupones que permiten que los padres utilicen fondos públicos para matrículas de escuelas privadas, incluyendo matrículas para estudiantes con discapacidades, pueden quizás ayudar a mantener, o incluso revertir, el declive. El presente estudio examina el impacto a nivel estatal en Indiana del programa de cupones en escuelas católicas, las matrículas de estudiantes y los servicios de educación especial en los sistemas escolares de tres diócesis grandes. Los resultados abordan problemas relacionados con el aumento de las matrículas, el cambio de las características de la población estudiantil, los servicios de educación especial y las necesidades de desarrollo profesional del profesorado de estas escuelas. Los autores discuten las implicaciones del programa de cupones en la matrícula y la educación de los estudiantes con discapacidades en las escuelas católicas. Palabras clave: escuela de elección, cupones, escuelas católicas, educación especial Chèques-éducation pour le choix de l\u27école et éducation spécialisée dans les écoles catholiques diocésaines en Indiana Les écoles catholiques sont maintenant au coeur des programmes de chèques-éducation pour le choix de l\u27école et des services d\u27éducation spécialisée. Étant donné que les inscriptions dans les écoles catholiques ont diminué au cours des dernières décennies, les programmes de chéques-éducation qui permettent aux parents d\u27utiliser des fonds publics pour les frais de scolarité d\u27écoles privées - y compris la scolarité des élèves handicapés - pourraient aider ou même inverser ce déclin. Cette étude examine l\u27impact du programme de chèques-éducation sur les écoles catholiques dans l\u27ensemble de l\u27État de l\u27Indiana, les inscriptions des élèves et l\u27éducation spécialisée dans trois vastes systèmes d\u27écoles catholiques diocésaines. Les constatations traitent des problèmes liés à l\u27augmentation des inscriptions, aux changements dans la population des élèves, aux services d\u27éducation spécialisée et aux besoins en développement professionnel des enseignants de ces écoles. Les auteurs présentent les conséquences du programme de chèques-éducation sur les inscriptions et l\u27enseignement aux élèves handicapés dans les écoles catholiques.

Island closure feasibility study power analysis results for Dassen and Robben islands

The power analysis for penguin responses to fishing around Dassen and Robben islands has been completed. Response variables considered are chick condition, active nest proportion, fledging success, chick growth, foraging path length, and foraging trip duration. Although complete results are given here only for the first two of these variables, overall there are clear indications regarding the residual variances associated with these variables. Those variances are now estimable for Dassen and Robben islands with sufficient reliability to allow a decision on whether an experimental closure programme could yield definitive conclusions regarding the impact of fishing close to island colonies on penguin demographics within a realistic time span. Thus the purpose of the feasibility study has been achieved and the study can be concluded, with the island closure experiment commenced for these two islands. Definitive results from the experiment can be expected for both islands with about 2–4 years’ additional data

Results of an alternative pelagic biomass series for the relationship with penguin adult survival

A key component of the Robben Island penguin population model (Robinson and Butterworth 2011a,b) is the relationship between annual penguin adult survival and the abundance of small pelagic fish. This is of primary importance as it enables one to produce penguin population projections based on different future small pelagic abundance levels. The sardine and anchovy OMPs may then be designed to take into account the risk to penguins of reaching a low pelagic abundance level

Robustness of the penguin population model estimator

The robustness of an estimator may be investigated by assuming that the “true” operating model is in fact different (for example, a constant may have a different value or a key relationship may have a different functional form to that assumed by the estimator). Data generated from this “reality” are then fitted using the estimator. The distributions of the results are then compared to the corresponding “true” values of the operating model

Island closure feasibility study power analysis

This paper indicates how it is planned to extend the general linear model (GLM) analyses by Robinson (2013) to estimate the power of the Island Closure Experiment. Statistical power reflects the probability that an experiment will detect an effect if it exists
