POGO Instabilities Suppression Evaluation

A dynamic (frequency response) analysis was made of a liquid oxygen feed system consisting of a low-speed inducer, a high-speed main pump and a positive displacement pulser utilized for simulating pogo induced pressure oscillations. Based on the results of the analysis, an active control system for suppression of pulser generated pressure oscillations was designed, fabricated and tested. The test results verified that the suppressor was effective in attenuating the generated pressure oscillations over the frequency range from 10 to 30 Hz

Effects On Different Intensities of Utilization Upon The Underground Parts of Short Grasses In West Central Kansas

Work on root systems of forage plants has indicated that a knowledge of root relationships is fully as important in determining the actual conditions of ranges or pastures as is knowledge of the effects of grazing upon aboveground portions of plants. This is especially true in arid or semiarid regions since plants of these areas are frequently subjected to long periods of drought, high temperatures, and high wind velocities. Some xeric plants have a thickened cuticular layer, stomates that open only at night, and other mechanisms that prevent loss of water that is absorbed by the roots. However, in plants of the short grass plains an extensive root system is the primary means of obtaining water that is needed for life processes during periods of stress. If the development of roots is impaired by bad grazing practices there is a reduction in the ability of plants to withstand drought and other adverse climatic conditions. The ability of a plant to produce abundant forage is also decreased by poorly developed underground parts. A knowledge of root systems, therefore, is essential in determining grazing practices that will insure the growth of well developed vigorous plants

Strategies in mechanical interventions for acute MI: facilitated and rescue PCI

Primary Percutaneous Coronary Intervention (PCI) is the superior strategy for treating acute ST-elevation myocardial infarction (STEMI) as an initial strategy within the first 6 hours from symptom onset. Facilitation of PCI by the use of pre-treatment, prior to planned PCI, with thrombolytic drugs or glycoprotein (GP) IIb/IIIa inhibitors has held theoretical promise for earlier infarct related arterial patency, but has failed to deliver on such promise.Thrombolysis as an initial strategy is inevitable in a large number of STEMI patients due to limited access to primary PCI. This strategy has limited success, and when it fails, rescue PCI has benefit and is recommended. Mechanical methods such as thrombectomy and distal protection, while having an intuitively plausible mechanism for benefit, have also failed to meet expectations and have a limited role in acute STEMI

Exploring the COVID-19 Pandemic Impact on Hawai\u27ian Small Businesses

The COVID-19 pandemic has a profound and devastating impact on small businesses across the globe, especially and noticeable in the state of Hawai’i. The virus outbreak has disrupted the operations of all small business industries. This qualitative case study addressed the general problem of how the COVID-19 pandemic impacted Hawai’ian small businesses. The research provided a detailed understanding of the COVID-19 pandemic by focusing on key research questions to comprehend the problem statement. The case study findings provided an understanding of how small business owners and managers managed to remain sustainable since the start of the pandemic outbreak. Collectively, 15 small business owners and managers provided detailed life experience information to inform these research findings. Furthermore, the research case study findings indicated how Hawai’ian small business owners and managers became adaptive and innovative in their business strategies as the pandemic outbreak worsened. The research identified essential lessons further to educate business leaders, students, and scholars. Notably, the research provided recommendations for future research and application to professional practice

Surface Temperature, Body Temperature, and Heart Rate as Affected by Immersing the Feet of Conditioned Basketball Players in Cold Water Bath

The purpose of this study was to determine whether surface temperature of the feet, body temperature, and heart rate are affected by immersing the subjects\u27 feet in a cold water bath of 34° 40°Fahrenheit before and after basketball practice sessions. Twelve male freshman basketball members at South Dakota State University participated in the study conducted over a period of four weeks and four days during the last part of the 1967-1968 basketball season. Each subject was tested six times during this period. The paired i comparison was used to divide the subjects into pairs. Each pair was divided randomly into experimental and control groups. Surface temperature of the feet, body temperature, and heart rate was taken for each subject before practice, immediately after practice, five minutes after practice, and ten minutes after practice. The experimental group immersed their feet in a cold water bath before practice and three minutes after practice. The members of the control group rested during this period. The investigator was concerned with the mean gain or loss between the groups. As a result of the statistical analysis of the data obtained, the investigator found that surface temperature of the feet showed a statistical significance during the short recovery period. Body temperature and heart rate showed no statistical significance, but were lower for group using the cold water bath than for the group observing the rest period

Sustaining schools as learning communities: Achieving a vision of the possible

Thesis (PhD) - Indiana University, School of Education, 2007School change efforts to develop schools as learning communities result in a school that is constantly learning how to improve and thus constantly changing. This collective case study of four schools involved in a four-year reform effort begins to examine the issue of sustainability in a learning community. First, this study develops a framework for considering whether a school is a learning community, beginning with the five disciplines of Peter Senge. It then discusses the need for collaborative inquiry with the characteristics of collaboration, inquiry stance, use of data, reflection, and public sharing. Finally the framework identifies five factors whose presence aid in sustaining a learning community. Documents during the implementation phase of the reform effort are examined to characterize the status of the schools as learning communities at the end of the effort. Then four years later follow-up data is collected using interviews, document analysis, and observations. Findings indicate that none of the schools have continued as envisioned by the reform effort. Changes to the environment in which each of these schools operates has impacted that sustainability to varying degrees. While there are some aspects of the reform effort still present, teachers involved in the effort were unable to impact whole school change in the years following the initiative, but have sustained the change work on an individual, though limited basis. In addition to the factors found by others to affect school reform (leadership, resources, support, time), this study suggests smaller faculty size may assist development of schools as learning communities. Commonalities between the experiences of the four schools suggest that teachers experience a sense of loss and limitation when reform efforts are not continued, though they continue the efforts on an individual basis. Additionally, though the change of culture required in this whole school reform effort provided a challenge, there were some examples of cultural change occurring. Finally, this study notes that the elements, processes, and practices interact in a complex way that requires more study to understand both how to approach development of schools as learning communities, as well as their sustainability
