A Long Duration Orbital Simulator (LDOS) Utilized in Technical Planning Activities

This paper describes the development and use of a long duration orbital simulator (LDOS). The LDOS capabilities, options, accuracy, and central processing unit (CPU) usage are discussed. The applications described using the LDOS are associated with (a) Manned Space Flight Network (MSFN) support of long duration missions, (b) environmental effects on high earth orbits and (c) long term orbit decay. The appendix depicts the salient portions of the math model

Community Assessment Scales: The State of the Art

Community development activities are founded on the assumption that citizens have some concept of a good community toward which they want to move. Attention needs to be given to how community developers can determine citizen values and attitudes about the type of community that they want. Community assessment scales (CAS\u27s) have been used as one means of measuring community attitudes and desires. This paper explores the state of the art of the development and use of CAS\u27s. The conclusions are that there has been only minimal use of CAS\u27s and that there are many conceptual and methodological problems with the existing scales. It is suggested that CAS\u27s, if properly designed, could be useful and practical tools for community development

Patterns of past and recent conversion of indigenous grasslands in the South Island, New Zealand

We used recent satellite imagery to quantify the extent, type, and rate of conversion of remaining indigenous grasslands in the inland eastern South Island of New Zealand in recent years. We describe the pattern of conversion in relation to national classifications of land use capability and land environments, and ecological and administrative districts and regions. We show that although large areas of indigenous grasslands remain, grassland loss has been ongoing. Indigenous grassland was reduced in the study area by 3% (70 200 ha) between 1990 and 2008. Almost two-thirds of post-1990 conversion occurred in threatened environments with less than 30% of indigenous cover remaining, primarily in the Waitaki, Mackenzie and Central Otago administrative districts. This conversion occurred primarily on non-arable land. In the Mackenzie and Waitaki districts the rate of conversion in 2001-2008 was approximately twice that in 1990-2001. Opportunities to protect more of the full range of indigenous grasslands lie with the continuing tenure review process in these districts

Finite volume corrections to pi-pi scattering

Lattice QCD studies of hadron-hadron interactions are performed by computing the energy levels of the system in a finite box. The shifts in energy levels proportional to inverse powers of the volume are related to scattering parameters in a model independent way. In addition, there are non-universal exponentially suppressed corrections that distort this relation. These terms are proportional to exp(-m_pi L) and become relevant as the chiral limit is approached. In this paper we report on a one-loop chiral perturbation theory calculation of the leading exponential corrections in the case of I=2 pi-pi scattering near threshold.Comment: 17 pages, 2 figures, 1 table.

Understanding Resident-to-Resident Conflicts in Long Term Care Settings from the Perspective of Administrative Staff

Assisted living facilities are expanding in response to the growing population of older adults in the United States. Assisted living facilities offer a wide array of services including memory care. Research has shown that a majority of assisted living facilities have residents with cognitive impairments living along with non-cognitively impaired individuals (i.e., mixed populations). Little is known about the conflicts that may arise between cognitively and non-cognitively impaired residents in a mixed population. The present study hoped to better understand what conflicts occur, how direct care staff are trained to handle these conflicts, from the perspective of assisted living facility administrators. The 11 administrators who agreed to participate filled out a survey via Qualtrics Survey Software answering questions related to this phenomenon. The results from the study indicated that conflicts do arise in mixed population of residents, with common conflict themes including disruptive behaviors, such as wandering or repeating the same stories. Participating administrators indicated a wide variety of frequencies of conflict and indicated they do receive specific complaints about cognitively impaired individuals from non-cognitively impaired residents. Participants indicated there is training to handle resident conflicts, such as distraction, redirection or education, but there were mixed responses as to whether facilities had specific protocols in place. The small sample size diminishes generalizability of findings; however, the current study can serve as a catalyst for future studies concerning conflicts among mixed populations of residents

Development of Prediction Relationships for Water Requirements with Irrigation Cooling

A model for predicting leaf temperatures during an off-on mist cycle is presented. The model uses a combination of energy budget and aerodynamic techniques. The model was tested for dry leaf temperature and evapotranspiration predictions using average hourly data from Arizona. The accuracy was good. It was also tested for dry leaf temperature predictions using two to three minute data with a widely varying net radiation. When reasonable values of stomatal resistance were used, the agreement was again good. The model was tested for prediction of wet leaf temperature prediction with a ten minute on, fifty minute off mist irrigation cycle. The agreement was fair when using reasonable input parameters. The poorest predictions were during the mist on cycle

The Ritual Experience

What initially attracted me to this project was a combination of several factors. The first be¬ing that I have had a growing interest in the de¬sign of religious structures, wondering why are churches designed the way that they are? How do a religious affiliation’s beliefs affect the de¬sign of a place of worship, and how are they reflected in the place of worship? Regarding the site that was chosen, Messiah Lutheran Church has recently gone through a strategic planning process and, within the last couple weeks, has adopted a new strategic min¬istry plan document. A vision statement within this document reads: “Messiah will be located on a large, highly vi¬ible campus with state-of-the-art facilities with worship attendance over 3,000 each week and a Christian Day School of 500 plus students…Facilities will provide opportunities for continu¬ous growth for large groups, small groups, and individuals in the Core Values of Messiah….” While the current site of Messiah may not be as big as the church would require to fulfill this vision, it is not utilized very efficiently in its cur¬rent state. So, one of the purposes of this proj¬ect besides my own interest in the subject, is to provide the church with an idea of what could be done to further improve the facilities at the current site

The sequences of human and bovine genes of the phosphate carrier from mitochondria contain evidence of alternatively spliced forms.

The sequences of the human and bovine genes for the phosphate carrier from the inner membranes of mitochondria have been determined. The genes have similar structures and each is divided into nine exons. In both genes, two exons, named IIIA and IIIB, are closely related, and they appear to the alternatively spliced. The human exon IIIB sequence is found in a published human heart cDNA sequence, and bovine exon IIIA forms part of a published bovine heart cDNA sequence. By further examination of the human heart cDNA library, sequences arising from both alternatively spliced forms of the phosphate carrier have been characterized. Both forms were also found in several bovine tissues, but the ratios of expression of the two forms varied. The form containing exon IIIA was expressed most highly in bovine heart and liver, less highly in brain and kidney, and only in low amounts in lung. The opposite hierarchy was found for the form containing exon IIIB; it was most highly expressed in lung and least in heart and liver. The alternative splicing mechanism affects amino acids 4-45 of the mature phosphate carrier protein, which is believed to form one of six transmembrane segments of the phosphate carrier and to emerge into a large extramembranous loop. The alternative splicing mechanism changes 13 and 11 amino acids in the human and bovine carrier proteins, respectively. As the function of this region of the phosphate carrier is not known, the effects of the changes on carrier function are not understood at present

IMPACT OF A MORE INTENSIVE INSECT PEST INFESTATION LEVEL ON COTTON PRODUCTION: TEXAS HIGH PLAINS

This study evaluated implications of increased bollworm problems in a 20-county area of the Texas High Plains relative to cotton yields and economic impact. Results did not indicate a serious effect of bollworms upon lint yield when insecticides were used for control. However, estimated annual reduction in farmer profit due to the bollworm for 1979-81 was over $30 million. Yields were estimated to decline about 300,000 bales without insecticide use and about 30,000 bales with insecticide use. This decline suggests potentially serious implications for the comparative economic position of cotton in this region if insecticide resistance were to develop among insect pests.Crop Production/Industries,
