The Status of Metric Conversion in Industrial Education Programs in Utah With Recommendations for Statewide Training Programs

The purpose of this study was to obtain information from Industrial Education teachers in Utah concerning their feelings and attitudes toward conversion to the Metric System in the United States and to determine their present familiarity with that system. The study was also designed to identify potential problem areas which would tend to influence educational programs on the Metric System for Industrial Education teachers in Utah. A select sample of four-hundred twenty-three Industrial Education teachers representing over twenty occupational areas was chosen as the population for the study. Two-hundred ninety-seven usable questionnaires (70.2 per cent) were returned and tabulated as follows 1. the total group of Industrial Education teachers responding to the survey 2. each occupational area was tabulated separately, and 3. each occupational area was compared to the total group of Industrial Education teachers responding to the survey. The study focused on obtaining answers to the five following questions: 1. How familiar are Industrial Education teachers in Utah with the base units of the Metric System? 2. Which subject area teachers have the least understanding of the base units of the Metric System? 3. Which sources of Metric System information have been of greatest value to Industrial Education teachers as sources of general and teaching information? 4. What types of educational programs would be appropriate for familiarizing Industrial Education teachers with the Metric System? 5. Which type s of metric information are currently being used by Industrial Education teachers in Utah? The analysis of the data and the basic findings of the study warranted the following conclusions: 1 . Industrial Education teachers in Utah are in need of instruction in various portions of the Metric System of measurement. Electronics teachers as a group, do not need further instruction, since electronic s is already taught using metric terminology and measurement. 2. Woods teachers do not see the necessity for metric measurement in their occupation, nor do they see economic advantages in the conversion. 3. Curriculum guide s in Utah have been of little value to Industrial Education teachers in Utah, as sources of metric information. 4. Most subject area textbooks are not written in Metric terminology and are of little value to Industrial Education teachers as sources of metric information. 5. The Utah State Board of Education needs to provide additional guidance for Industrial Education programs on conversion to the Metric System of measurement. 6. General informational programs on the Metric System as well as specific instruction on the use and application of the Metric System of measurement are needed by Industrial Education teachers in Utah

Efficacy of a Topical Formulation Containing Emodepside and Praziquantel (Profender®, Bayer) against Nematodes in Captive Tortoises

Gastrointestinal parasites are commonly diagnosed in captive tortoises. In response, fenbendazole has traditionally been used as an anthelmintic, either in single or repeated doses. However, fenbendazole requires oral administration and the process can be very challenging in some individuals. A topical preparation containing emodepside and praziquantel (Profender®, Bayer, Leverkusen, Germany) is promoted as effective against a broad range of nematodes, trematodes, and cestodes. Although this product is currently only licensed for administration to cats, previous studies have shown positive results with tortoises. The aim of this study was to determine the efficacy of Profender against oxyurid and ascarid parasites in captive tortoises. This was achieved by quantifying nematode eggs per gram (EPG) in feces using a modified McMaster technique before (Day 0) and after (Days 14 and 33) topical application of Profender at a dose rate of 21.5 mg emodepside and 85.5 mg praziquantel per kilogram. Twenty-nine tortoises, representing four different species, were enrolled in this study of which 14 (48%; including Testudo hermanni and Testudo graeca) were positive for intestinal nematodes. Following treatment, the oxyurid EPG was slightly increased on Day 14 but declined significantly by Day 33 (59.7% reduction; P = 0.01), indicating a slow onset of effect and moderate efficacy 33 days posttreatment; however, no conclusions regarding efficacy against ascarids can be drawn from this study. Topical application of emodepside and praziquantel was well tolerated in our tortoise population and, therefore, could be considered as a useful alternative anthelmintic treatment protocol for captive tortoises

Gastric myoelectric activity during cisplatin-induced acute and delayed emesis reveals a temporal impairment of slow waves in ferrets: effects not reversed by the GLP-1 receptor antagonist, exendin (9-39).

Preclinical studies show that the glucagon-like peptide-1 (GLP-1) receptor antagonist, exendin (9-39), can reduce acute emesis induced by cisplatin. In the present study, we investigate the effect of exendin (9-39) (100 nmol/24 h, i.c.v), on cisplatin (5 mg/kg, i.p.)-induced acute and delayed emesis and changes indicative of 'nausea' in ferrets. Cisplatin induced 37.2 ± 2.3 and 59.0 ± 7.7 retches + vomits during the 0-24 (acute) and 24-72 h (delayed) periods, respectively. Cisplatin also increased (P<0.05) the dominant frequency of gastric myoelectric activity from 9.4 ± 0.1 to 10.4 ± 0.41 cpm and decreased the dominant power (DP) during acute emesis; there was a reduction in the % power of normogastria and an increase in the % power of tachygastria; food and water intake was reduced. DP decreased further during delayed emesis, where normogastria predominated. Advanced multifractal detrended fluctuation analysis revealed that the slow wave signal shape became more simplistic during delayed emesis. Cisplatin did not affect blood pressure (BP), but transiently increased heart rate, and decreased heart rate variability (HRV) during acute emesis; HRV spectral analysis indicated a shift to 'sympathetic dominance'. A hyperthermic response was seen during acute emesis, but hypothermia occurred during delayed emesis and there was also a decrease in HR. Exendin (9-39) did not improve feeding and drinking but reduced cisplatin-induced acute emesis by ~59 % (P<0.05) and antagonised the hypothermic response (P<0.05); systolic, diastolic and mean arterial BP increased during the delayed phase. In conclusion, blocking GLP-1 receptors in the brain reduces cisplatin-induced acute but not delayed emesis. Restoring power and structure to slow waves may represent a novel approach to treat the side effects of chemotherapy

Uniqueness and other aspects of the optical phase problem

Thesis (Ph. D.)--University of Rochester. College of Engineering and Applied Science, Institute of Optics, 1985. This thesis was digitized by the Institute of Optics in 2014 and was determined to have lapsed into the public domain. If you are the author and have questions about the digitization of your work, please contact Kari Brick, Graduate Program Coordinator for the Institute of Optics, at [email protected]. Other contact information for the Institute is available at http://www.optics.rochester.eduThe phase problem is examined as it occurs in stellar speckle interferometry, wherein one assumes that the image to be reconstructed is of finite spatial extent Algorithms for reconstructing the Fourier phase of an image are studied, as well as a detailed investigation of the two-dimensional uniqueness question undertaken. Criteria for unique phase retrieval are derived for two-dimensional discrete objects, with particular emphasis placed on the importance of support constraints. The support is shown to have a profound effect on the uniqueness properties of the function defined upon it. It is established that some, such as Eisenstein's support, ensure a single solution independent of the function defined on that region, excluding mild restrictions necessary to define the region. An alternate method of demonstrating the solution uniqueness associated with Eisenstein's support is presented. Moreover, this approach is generalized to produce a large number of supports which are not described by Eisenstein's criterion, but which nonetheless guarantee solution uniqueness. An algorithm is developed to test an arbitrary discrete support for membership in this special family. A related criterion is also derived which, when satisfied, ensures solution uniqueness when support information is explicitly incorporated into a reconstruction algorithm. A one-dimensional phase retrieval technique for stellar speckle interferometric imaging is presented, which is based on the identification and manipulation of complex zeros. The algorithm is applied to data produced in a laboratory simulation of stellar speckle. It is found that it is possible to recover one-dimensional images in this manner, however, the quality of the reconstruction is generally no better than that produced by the Knox-Thompson algorithm, and the roots method is substantially more difficult to implement. A brief survey of modulus-only reconstruction algorithms is undertaken, with an emphasis on Fienup's iterative approach. An implementation of Fienup's algorithm proves to be capable of reconstructing a limited number of objects from the Fourier modulus, but in general requires stronger constraints than nonnegativity to converge to the correct solution. The algorithm is capable of reconstructing rather complex images defined on Eisenstein's support, in addition to others which are defined on a sufficiently irregular region
