Space biology initiative program definition review. Trade study 2: Prototype utilization in the development of space biology hardware

The objective was to define the factors which space flight hardware developers and planners should consider when determining: (1) the number of hardware units required to support program; (2) design level of the units; and (3) most efficient means of utilization of the units. The analysis considered technology risk, maintainability, reliability, and safety design requirements for achieving the delivery of highest quality flight hardware. Relative cost impacts of the utilization of prototyping were identified. The development of Space Biology Initiative research hardware will involve intertwined hardware/software activities. Experience has shown that software development can be an expensive portion of a system design program. While software prototyping could imply the development of a significantly different end item, an operational system prototype must be considered to be a combination of software and hardware. Hundreds of factors were identified that could be considered in determining the quantity and types of prototypes that should be constructed. In developing the decision models, these factors were combined and reduced by approximately ten-to-one in order to develop a manageable structure based on the major determining factors. The Baseline SBI hardware list of Appendix D was examined and reviewed in detail; however, from the facts available it was impossible to identify the exact types and quantities of prototypes required for each of these items. Although the factors that must be considered could be enumerated for each of these pieces of equipment, the exact status and state of development of the equipment is variable and uncertain at this time

Calvin Coolidge\u27s Afro-American Connection

In the wake of President Warren G. Harding\u27s death and the entry of Calvin Coolidge in the White House as chief executive in August, 1923, blacks, like the bulk of ordinary white Americans, were uncertain of what to expect. Nonetheless, those close to the prior presidential administration, whether black or white, had clear reason to believe that Coolidge was preeminently qualified to carry on in the fashion of his predecessor. They anticipated his continued implementation of Republican policies in accord with political promises which had led to the party\u27s overwhelming electoral victory in 1920. Indeed, Harding\u27s breaking of tradition to allow his Vice President Coolidge to sit with the presidential cabinet ensured that the new chief executive understood and was prepared administratively to deal with tariff issues, tax-reform legislation, measures for the reduction of the public debt, and the host of other political promises Republicans made in 1920. In 1924 Coolidge, however, had to win nomination and election to the office in his own right in order to continue the quest for legislation consonant with the Republican party political mandate received four years earlier

Tennessee’s Unique Religious Protections in Employment: Do They Mean What They Say?

Tennessee has a long history of strongly held and diverse religious beliefs and practices. Equally firmly established is its “at-will” employment rule that allows businesses to create and control their workforces to maximize operations and profits to the benefit of employers and employees. When an employee’s religious beliefs conflict with his obligations to his employer, state and federal laws resolve the tension. Employees who experience this tension and feel they have been discriminated against based on their religion generally have the choice to bring their claims of discrimination under federal law, state law, or both. Because claims under federal law may be removed to federal court, and because state courts are generally perceived to be more favorable to employees, some employees strategically elect to pursue only selected state law claims. An employee might also be forced to bring a claim only under state law if she works for a small employer, since the federal law’s reach is limited to employers with at least fifteen employees. This Article examines whether a Tennessee employee who brings claims only under Tennessee’s statutory protection against religious discrimination in employment has the same protections as he would if he proceeded under federal law. Part I discusses employers’ obligations under the Tennessee Human Rights Act (“THRA”), the primary Tennessee religious anti-discrimination statute, and Title VII of the Civil Rights Act of 1964 (“Title VII”), the primary federal religious anti-discrimination law. Part II discusses the background of both the THRA and Title VII and how it informs the analysis. Part III proposes that the THRA not be interpreted to import the reasonable accommodation requirement from Title VII. This interpretation is consistent with the textual language of the statute, courts’ interpretation of the Tennessee Disability Act, existing case law, and Tennessee’s history of limiting exceptions to the at-will employment doctrine. The Article proposes that this different interpretation is more consistent with the THRA as it is currently written and invites discussion of whether this interpretation is ultimately better for employees and employers

The Effects of Sorbic Acid in High Moisture Sorghum Grain Diets on Performance of Weanling Swine

Three experiments were conducted with 288 weanling pigs to determine the effects of sorbic acid (SA) added to dry (DSG), high moisture (HMSG) or reconstituted (RSG) sorghum grain diets on gains and feed conversion. Dietary treatments for Exp. 1 were: DSG with and without .1% SA; HMSG with .1% SA and RSG with .1% SA. The DSG diets were fed ad libitum. The HMSG and RSG diets were mixed fresh from oxygen-limiting storage every 3 and 7 d and were also fed ad libitum. Pigs fed RSG diets consumed more feed than those fed HMSG diets (P\u3c.08). Performance was similar between pigs fed DSG diets without or with SA. Dietary treatments for Exp. 2 and 3 consisted of sorghum grains reconstituted to two moisture contents (MC), with additions of either 0, .05 or .I% SA. The diets were mixed fresh from oxygen-limiting storage every 7 d and fed ad libitum. In Exp. 2 and 3, pigs fed the higher MC diets were more efficient in feed conversion (P\u3c.03) than those fed the lower MC diets. In Exp. 3, a quadratic response (P\u3c.04) for average daily gain and average daily feed intake was observed for the main effect of SA. Feed efficiency improved (P\u3c.05) in a linear fashion as SA levels were increased in the diets. The results of these experiments indicate that weanling pigs may be fed HMSG or RSG without adverse effects on pig performance. Inconsistencies in pig response to SA were observed. Feed temperature measurements indicated that SA prevented heat production in the RSG diets for at least 10 d after removal from oxygen-limiting storage, while diets without SA became moldy within 5 d

Weaining Weight Response of Pigs to Simple and Complex Diets

Five experiments were conducted to determine (1) the value of simple vs complex diets on gains and feed conversion of pigs weaned at a constant age but varying in weight, (2) the optimum post-weaning time to change from a complex to a simple diet and (3) the effect of previous treatment on subsequent performance

1954: Abilene Christian College Bible Lectures - Full Text

Preface The 1954 Abilene Christian College Lectureship was one of the best attended and most successful in the history of the school. Considerable interest was manifested in the timely theme, “Overcoming Dangerous Tendencies,” and in the two special topics, “Ways and Means of Doing Mission Work,” and “Caring For Widows and Orphans.” The reports from the mission fields were highly stimulating, and all in all, the speeches were unusually high caliber. The Panel Discussions were also on timely subjects and well presented. They received a warm response, as did also the thirty classes that were conducted each day. These classes were taught by persons expert in their particular fields, and covered a wide range of interests to the faithful, working Christian. We at Abilene Christian College predict for this book of Lectures a wide and hearty reception, and believe that its reading will issue in profit to the individual and to the church at large. J. D. Thomas Lectureship Directo

Relevance of large litter bag burial for the study of leaf breakdown in the hyporheic zone

Particulate organic matter is the major source of energy for most low-order streams, but a large part of this litter is buried within bed sediment during floods and thus become poorly available for benthic food webs. The fate of this buried litter is little studied. In most cases, measures of breakdown rates consist of burying a known mass of litter within the stream sediment and following its breakdown over time. We tested this method using large litter bags (15 x 15 cm) and two field experiments. First, we used litter large bags filled with Alnus glutinosa leaves (buried at 20 cm depth with a shovel) in six stations within different land-use contexts and with different sediment grain sizes. Breakdown rates were surprisingly high (0.0011–0.0188 day-1) and neither correlate with most of the physico-chemical characteristics measured in the interstitial habitats nor with the land-use around the stream. In contrast, the rates were negatively correlated with a decrease in oxygen concentrations between surface and buried bags and positively correlated with both the percentage of coarse particles (20–40 mm) in the sediment and benthic macro-invertebrate richness. These results suggest that the vertical exchanges with surface water in the hyporheic zone play a crucial role in litter breakdown. Second, an experimental modification of local sediment (removing fine particles with a shovel to increase vertical exchanges) highlighted the influence of grain size on water and oxygen exchanges, but had no effect on hyporheic breakdown rates. Burying large litter bags within sediments may thus not be a relevant method, especially in clogged conditions, due to changes induced through the burial process in the vertical connectivity between surface and interstitial habitats that modify organic matter processing

Occupation of racial grief, loss as a resource : learning from ‘The Combahee River Collective Black Feminist Statement'

The methodology of ‘occupation’ through rereading The Combahee River Collective Black Feminist Statement (The Combahee River Collective, in: James, Sharpley-Whiting (eds) The Black Feminist Reader. Blackwell Publishers Ltd., Oxford, pp 261–270, 1977) demonstrates the necessity of temporal linkages to historical Black feminist texts and the wisdom of Black feminist situated knowers. This paper argues that racism produces grief and loss and as long as there is racism, we all remain in racial grief and loss. However, in stark contrast to the configuration of racial grief and loss as something to get over, perhaps grief and loss can be thought about differently, for example, in terms of racial grief and loss as a resource. This paper questions Western Eurocentric paternalistic responses to Black women’s ‘talk about their feelings of craziness… [under] patriarchal rule’ (The Combahee River Collective 1977: 262) and suggests alternative ways of thinking about the psychological impact of grief and loss in the context of racism. In this paper, a Black feminist occupation of racial grief and loss includes the act of residing within, and the act of working with the constituent elements of racial grief and loss. The proposal is that an occupation of racial grief and loss is a paradoxical catalyst for building a twenty-first century global intersectional Black feminist movement

Response of Different Genetic Lines of Boars to Varying Levels of Dietary Calcium and Phosphorus

Two experiments were conducted to determine the effect of various levels of dietary calcium (Ca) and phosphorus (P) on performance, soundness and blood and bone parameters of different genetic lines of boars fed under variable environmental conditions. The first experiment compared different genetic lines of boars fed two levels of dietary Ca and P. Forty purebred (Large White) and Nebraska Gene Pool boars were allotted by breed and initial weight to two levels of dietary Ca and P (.65 Ca/.50% P and 1.3% Ca/1.0% P)
