We investigate how electron correlation and band structure affect laser-induced demagnetization. Pure electron-electron scattering cannot explain the large spin moment reduction observed, and the band relaxation and exchange splitting are essential to the spin change.

Concentrated feed diets have been shown to drastically increase the rate of the cribbing, an oral stereotypy in horses, but the specific component causing the rise has not been identified. Furthermore, the mechanism through which feed affects cribbing has not been explored. In the first experiment of this study, we quantified the latency to crib and number of cribs in 15. min after the horses tasted various grain, sugar, and artificial sweetener solutions. Undiluted grain stimulated the most cribs (P< 0.01) compared with all other solutions, and shortest latency to crib, although this was significantly higher only when compared with diluted grain (P = 0.03). In Experiment 2, latency to crib and number of cribs in 15. min after the grain and sugar solutions were administered via nasograstric tube were also evaluated. There were no statistical differences among cribbing responses to grain, fructose, and water administered directly to the stomach although grain stimulated cribbing behavior more quickly than 10% fructose (P = 0.03) and 100% tap water (P = 0.04). These results confirm that highly palatable diets, possibly mediated through the opioid and dopaminergic systems, are one of the most potent inducers of cribbing behavior. The highly palatable taste remains the probable "cribogenic" factor of concentrated diet, although gastric and post-gastric effects cannot be excluded. © 2017 Elsevier B.V.

Objective: To determine the diagnostic accuracy of tissue impedance measurement interpretation (TIMI) for determining correct versus incorrect Veress needle placement in feline cadavers. Study Design: Prospective, randomized, blinded trial. Study Population: Cat cadavers (n=24). Methods: Two laparoscopists (1 experienced, 1 novice), blinded to TIMI, placed reusable Veress needles in study subjects in a randomized order. A third individual interpreted impedance measurements as consistent with correct versus incorrect placement. Veress needle tip locations were marked by injecting contrasting colors of India ink. Tissue dissection was performed to localize ink. Sensitivity, specificity, accuracy, precision, and kappa statistics for TIMI for placements by the experienced and novice laparoscopist were determined. P<.05 was considered significant. Results: TIMI identified 36/38 correct and 2/10 incorrect placements. TIMI identified 2/2 bowel perforations but was unable to identify 8 inappropriate placements in the retroperitoneal fat pad. Impedance measurement interpretation had 94.7% sensitivity, 20% specificity, 79.2% accuracy, and 81% precision overall. Agreement between TIMI and Veress needle location was absent (kappa=-0.15, P=.01) for placements by the experienced laparoscopist and substantial (kappa=0.78, P<.01) for the novice laparoscopist. Conclusions: Failure of TIMI to identify placement in the retroperitoneal fat pad resulted in poor accuracy. Small cat size limited the number of appropriate placement sites, perhaps resulting in excessively dorsal placements. Use of TIMI may increase detection of clinically significant inappropriate Veress needle placements, like bowel perforations, and decrease installment phase complications. Further evaluation of Veress needle placement with and without TIMI is warranted. © Copyright 2013 by The American College of Veterinary Surgeons.

Proceedings ACM SIGUCCS User Services Conference | Year: 2010

Exposing faculty to one another's instructional challenges and accomplishments and enabling them to network has been the motivation behind an annual conference at the University of Maryland for nearly 20 years. The instructional technology experiences of three intrepid early adopters were showcased in the University's first half-day Teaching with Technology symposium in 1993. By 1999 the symposium blossomed into a full-day conference where presentations by 12 instructors continued to emphasize different forms of technology in the classroom, but, oddly enough, integrated only minimal use of technology in the presentations themselves. As technology in the classroom became ubiquitous, the sponsoring conference hosts believed it was time to change the focus of the conference from technology in teaching to innovation in teaching and learning. This paper will briefly trace lessons learned in the evolution of the Innovations in Teaching and Learning Conference [1]. It will additionally focus on our recent integration of technologies such as Twitter, lecture capture tools, QR codes and streamed broadcasting, which enable us to model uses of instructional technology tools and to make the conference available to a broader audience. © 2010 ACM.

Sustainability | Year: 2013

Are brief, single-issue videos an effective way to illuminate issues of sustainability online? Can web-based performance ignite positive social change? This article tracks an attempt by Beth Osnes and Mark Gammon to answer those questions. This article is primarily a methodological reflection of our pilot effort and recommendations for future attempts to accurately assess the effectiveness of web-based performance for social change.

In this paper, I describe the process the Office of Information Technology (OIT) followed in creating our Computing @ newsletter and other print materials while meeting our university branding requirements. I also describe our methodology for teaching these same processes to members of our faculty, staff, and graduate departments. It is not my intention to provide a word for word example of my presentation. Since the materials I will be referencing are all available online, it seems unnecessary to reproduce them in their entirety here. I will go into each section in greater detail as I speak about our specific experiences in regards to these topics.

In Kentucky's Eastern Coal Fields physiographic region, mining and reclamation activities often result in stream modification, potentially leading to the creation of new ponds and reservoirs. Incorporation of these changes as part of updates to the National Hydrography Dataset is proceeding slowly. The 2001-2005 Kentucky Landscape Census modernization of the NLCD01 demonstrated the extremely dynamic characteristic of the landscape in that region of the state where major land cover changes are due to resource extraction. Timely, in-situ monitoring and assessment of waterbodies created or modified in permitted mining operations would prove costly for government agencies. This paper explores the use of multitemporal change analysis, based on Landsat 5 TM and aerial, multispectral imagery for the detection of new waterbodies in areas affected by mining activities.

Origin and early history of Die Methode des Eichzusatzes or The Method of Standard Addition with primary emphasis on its origin, early design, dissemination, and usage of terms is discussed. Die Methode des Eichzusatzes or literally 'the method of calibration addition' was first used and described by Hans Hohn in 1937 in his book Chemische Analysen mit dem Polarographen. Polarography was a very popular and much used technique well into the 1960s until the advent of modern spectroscopy. The literal English translation of Eichzusatzes into calibration addition comes from joining the verb, eichen, and the noun, Zusatz, which mean to calibrate and addition, respectively. The two-level design described by Kolthoff and Lingane was the design originated by Hohn and subsequently used by all early polarographers.

The Subscription Management System (SMS) developed at University of Florida/Institute of Food and Agricultural Sciences (UF/IFAS) is a distributed subscription and Extension clientele management system. This centralized system contains information about Extension program areas, newsletters, and clientele profiles. Extension agents can communicate with their clientele with personalized and relevant information tailored to a group of clients. The system provides Extension faculty with reports on clientele activities and their profiles to better understand their interests and to improve the delivery of Extension programs. The Distance Diagnostic and Identification System (DDIS) allows growers, Master Gardeners, Extension agents, and specialists at UF/IFAS and other locations to collaborate on the diagnosis of infestations, diseases, and other agricultural problems. EDIS, an Extension publication system at UF/IFAS, provides a wide range of information at users' fingertips. 0.
