A sensitive temperature measuring system

A sensitive temperature measuring system, providing an analog output proportional to sensor temperature, has been designed for use in the wall temperature control system of a cloud simulation chamber. A platinum resistance element is the sensor, and a precision wirewound resistor is the reference in a bridge circuit which uses four low cost operational amplifiers arranged to provide two precision 1000 Hz current sources. Problems with an initial bridge amplifier design were corrected in the final design by the use of a low Q bandpass amplifier for the bridge signal followed by a phase detector and an output low pass filter which reduces noise and allows fine adjustment of overall gain. Although a completed system was never built and calibrated, the breadboarded final design features r.m.s. output noise equivalent to 0.2 m°c, and drift over a period of several hours reducible to less than 3 m°c. System nonlinearity is a maximum of 0.6% when the instrument is calibrated over a 10°C range, and full scale accuracy is limited only by oscillator stability to about 4%. The cost of the system is sufficiently low that the system could be used wherever control or monitoring applications require a continuous signal proportional to sensor temperature difference from a reference value --Abstract, page ii

The Relationship Between Course Delivery Mode and Location with Course Success for Dual Enrolled Students

High school dual enrollment has increased dramatically in recent years, growing 75% nationally between academic years 2002-03 and 2010-11 (Borden, Taylor, Park, & Seiler, 2013). Proponents of dual enrollment programs cite long-term, positive student outcomes for dual enrollment students: higher GPAs in college as adults (Allen & Dadgar, 2012; Jones, 2014; Karp, Calcagno, Hughes, Jeong, & Bailey, 2007), higher first year persistence rates in college (Jones, 2014; Karp et al., 2007), faster time to degree completion (Allen & Dadgar, 2012; Ganzert, 2014; Hughes, 2016), and higher college graduation rates (Ganzert, 2014; Hughes, 2016). However, very little research has focused on short-term success for dual enrolled students. Course grades earned in dual enrollment programs become a part of the student’s official college transcript. As such, these grades can impact a student’s ability to be accepted at post-secondary institutions after graduation from high school. In addition, poor grades in dual enrollment courses can negatively affect satisfactory academic progress standards, thus impacting financial aid eligibility as an adult. Therefore, it is important to understand any factors which might improve the chances of student course-level success. This causal comparative study used ex post facto data from four community colleges to examine the correlation between course delivery location (high school or college campus) for college classes taken by dual enrolled students to student success as defined by final grades in those courses. In addition, this study examined the correlation between course delivery mode (face-to-face, hybrid, or online) for college classes taken by dual enrolled students to student success as defined by final grades in those courses. The study findings indicated dual enrolled students taking classes on high school sites had higher course grades compared to dual enrolled students taking classes on a college campus. A subset model utilizing data from just one college, however, indicated the opposite. The results also indicated that dual enrolled students taking classes delivered in face-to-face and hybrid modes had higher course grades compared to dual enrolled students taking classes delivered in a fully internet mode. Again, a subset model utilizing data from just one college indicated the opposite

Case Studies in Managing Collections That Grow

Almost all archivists have at one time or another confronted the issue of managing additions to existing archival or manuscript collections. Managing these types of collections can prove extremely challenging, even for experienced professionals. Archivists have several options for making these types of collections available to researchers, but it is not always clear which option is best. Archivists from Purdue University and Georgia State University will discuss two of the options in the following case studies on managing growing collections. These case studies are meant to serve as examples for other archivists who may be faced with managing similar collections. The case studies include justifications for each archivist’s plan of work, the methodology used, the results of the work, and what was learned from the process. Pros and cons relating to each situation are also addressed, and an evaluation form has been included that will help archivists decide what steps to take when dealing with their own expanding collections in the future

Additionally, the flute ensemble, including Becky Davis, April Davis, Pam Estes, Nancilou Poole, Jane Chu, and Debra Franks, performed. This recital took place on April 27, 1976, in the Mabee Fine Arts Center Recital Hall

The COMPTEL instrumental line background

The instrumental line background of the Compton telescope COMPTEL onboard the Compton Gamma-Ray Observatory is due to the activation and/or decay of many isotopes. The major components of this background can be attributed to eight individual isotopes, namely 2D, 22Na, 24Na, 28Al, 40K, 52Mn, 57Ni, and 208Tl. The identification of instrumental lines with specific isotopes is based on the line energies as well as on the variation of the event rate with time, cosmic-ray intensity, and deposited radiation dose during passages through the South-Atlantic Anomaly. The characteristic variation of the event rate due to a specific isotope depends on its life-time, orbital parameters such as the altitude of the satellite above Earth, and the solar cycle. A detailed understanding of the background contributions from instrumental lines is crucial at MeV energies for measuring the cosmic diffuse gamma-ray background and for observing gamma-ray line emission in the interstellar medium or from supernovae and their remnants. Procedures to determine the event rate from each background isotope are described, and their average activity in spacecraft materials over the first seven years of the mission is estimated.Comment: accepted for publication in A&A, 22 pages, 21 figure

More than a passive interest

Abstract The defeat of the Dyer anti-lynching bill in 1922 was a turning point in relations between black Americans and the Republican Party. Little is understood, however, about the role played in the debates by President Warren Harding. This article contends that Harding's conflicted approach to presidential leadership caused him to mishandle the bill. The President's inability to choose between restrained 'whig' leadership and a more active 'stewardship' role resulted in an unstable executive style. The Dyer bill's failure was affected by this dilemma as black hopes were alternately raised and dashed by Harding's indecision. The bitterness of the bill's ultimate defeat was thus heightened, with severe consequences for the Republican party's long term electoral relationship with black voters

Report: Telepaediatrics in Rural and Remote Australia and Canada

Rural and remote communities in Australia and Canada experience barriers to accessing healthcare services (1). These barriers are especially pronounced when attempting to access more specialized health care services, such as paediatric (2–4). Both countries have implemented programs that aim to bridge the gap between rural communities and specialized healthcare. One such service is telepaediatrics. Telepaediatrics, as part of telehealth, refers to any paediatric health-related service, network, or medical tool that transmits voice, data, images and information through telecommunication programs as part of providing health services (5–7). Telehealth services are ideal because they remove the need to relocate the rural patient to urban specialist sites (5–7). In a WHO survey (2010), 60% of member countries had telehealth services in place but only 30% of these programs were implemented as part of routin
