STOIC

Stoic is a non-fiction childhood trauma memoir. The theme of loss is explored through the manuscript as the author delves into the family dynamics prior to a devastating car accident and the stark realities afterward. The mother is left a paraplegic as a result of the accident. The story takes place in the 1960s and early 1970s. This is one family\u27s tragedy as told from a child\u27s point-of-view. Set in a post-WWII suburban community, the comparison of relative prosperity and the loss of normalcy are detailed. The author incorporates both her Norwegian and German heritage as the family struggles to cope with an invalid mother. Issues of faith are interwoven throughout the text. Stoic is the story of a loving father and his four children as they care for a paraplegic

Self-pollen interference is absent in wild radish (Raphanus raphanistrum, Brassicaceae), a species with sporophytic self-incompatibility

This is the publisher's version. It can also be found here:http://www.amjbot.org/content/94/5/896Explaining the diversity of mating systems and floral forms in flowering plants is a long-standing concern of evolutionary biologists. One topic of interest is the conditions under which self-pollination can interfere with seed set for flowering plants with a self-incompatibility system. We investigated the effect of self-pollen interference for wild radish, Raphanus raphanistrum, which has sporophytic self-incompatibility. We performed pollinations and determined seed set for plants grown in the greenhouse, using pollen mixtures representing either self- with outcross-pollen or outcross-pollen alone. Stigmas were collected for a subset of pollinated flowers to determine the number of pollen grains applied. Average seed set for the self/cross (5.13 seeds/pollination) and cross treatments (5.09 seeds/pollination) did not differ significantly. Stigmatic pollen loads averaged around 700 grains, an amount close to observed natural pollen loads on R. raphanistrum. We concluded that for R. raphanistrum in natural populations, self-pollen is unlikely to interfere with outcross-pollen success. This study is the first to investigate effects of self-pollen interference on seed set for a homomorphic species with sporophytic self-incompatibility where rejection occurs at the stigmatic surface

A resistivity study of hot short ferrous alloys

Resistivity measurements were performed at elevated temperatures on four special ferrous alloys and one commercial iron. The alloys were pure iron, iron with .023 per cent sulfur, iron with .33 copper, iron with .32 copper and .024 sulfur. Other elements were held to the minimum amounts possible in order to determine the actual effects of sulfur and copper. The commercial alloy was Armco Iron. Measurements of resistivity versus temperature were taken at slow heating rates to determine if the iron sulphide liquid film formed in the grain boundaries of red-short steels had any effect on the electrical resistivity --Abstract, page 7

The construction and analysis of an amplifier for ultrasonic research

“An amplifier to be used for ultrasonic pulse methods was constructed and tested. The frequency range lies between 100 cycles per second and 2 mega-cycles per second and, if tuned circuit plug-in units are used, may be increased to approximately 4 mega-cycles per second. Special demands upon the amplifier are discussed along with basic acoustic attenuation measurements in solid state physics”--Abstract, page ii

Femtosecond spectroscopy of the first events of the photochemical cycle in bacteriorhodopsin

The first steps in the photochemistry of bacteriorhodopsin (BR) are investigated with light pulses of 160 fs duration. Four samples are studied: (i) the purple membrane, (ii) deuterated purple membrane, (iii) BR trimers and (iv) BR monomers. In all samples the first intermediate J is formed within 430±50 fs. No isotope effect is observed in the formation of J upon deuteration, in contrast to previous reports with much higher excitation energies. Thus proton movement to or from the retinal Schiff's base is not relevant during the first step. Comparing the data for trimeric and monomeric BR suggests an upper limit of 50 fs for the transfer of excitation energy from the excitonically coupled trimer to a single retinal chromophore

Early picosecond events in the photo cycle of Bacteriorhodopsin

The primary processes of the photochemical cycle of light-adapted bacteriorhodopsin (BR) were studied by various experimental techniques with a time resolution of 5 × 10-13 s. The following results were obtained. (a) After optical excitation the first excited singlet state S1 of bacteriorhodopsin is observed via its fluorescence and absorption properties. The population of the excited singlet state decays with a lifetime τ1 of ~0.7 ps (430 ± 50 fs) (52). (b) With the same time constant the first ground-state intermediate J builds up. Its absorption spectrum is red-shifted relative to the spectrum of BR by ~30 nm. (c) The second photoproduct K, which appears with a time constant of τ2 = 5 ps shows a red-shift of 20 nm, relative to the peak of BR. Its absorption remains constant for the observation time of 300 ps. (d) Upon suspending bacteriorhodopsin in D2O and deuterating the retinal Schiff base at its nitrogen (lysine 216), the same photoproducts J and K are observed. The relaxation time constants τ1 and τ2 remain unchanged upon deuteration within the experimental accuracy of 20%

Modeling the influence of climate and management practices on water quality in Goodwater Creek experimental watershed

The entire dissertation/thesis text is included in the research.pdf file; the official abstract appears in the short.pdf file (which also appears in the research.pdf); a non-technical general description, or public abstract, appears in the public.pdf file.Title from title screen of research.pdf file (viewed on August 21, 2007)Includes bibliographical references.Thesis (M.S.) University of Missouri-Columbia 2006.Dissertations, Academic -- University of Missouri--Columbia -- Biological engineering.The objective of this study was to determine relationships among weather, runoff, water quality, and best management practice (BMP) implementation in reducing atrazine losses in the 7,250-ha Goodwater Creek Experimental Watershed in NE Missouri's Audrain and Boone Counties. Data were collected from 1993 through 2003. Regressions were conducted among water quality indicators, climatic variables, and the change in area protected by BMPs. Results showed significant decreases in atrazine concentrations for June and the combined months of April, May, and June. Covariate analysis of the effect of BMP protected area on atrazine concentrations showed that the time period analyzed was important. Inputs were developed for the Soil and Water Assessment Tool (SWAT) program. The SWAT model was able to simulate decreased atrazine concentrations with 4.5% of the watershed protected by grassed waterways. Changes in the amount of land in conventional, conservation, and no-till tillage systems also affected the simulated atrazine concentrations

Case Reports on Auditory Deprivation and Audiologic Management

Abstract 1- Introduction: Long-term follow-up appointments are beneficial for cochlear implant (CI) users. Several factors can influence individual auditory performance, even after years of experience with amplification use. Maintaining routine follow-up appointments with an audiologist can provide verification measures, auditory monitoring, and ongoing counseling to achieve optimal performance with CI technology. Case Presentation: An elderly, female patient with a monaural CI presented to the clinic with a significant decline in speech perception after years of use. Discussion: The goal of CI programming is to effectively convert acoustic input into a usable electric signal for each stimulated electrode to produce adequate auditory exposure and avoid the deleterious effects of auditory deprivation. Conclusion: Commitment to annual programming and follow-up is critical to maintaining the stability of auditory performance and speech perception abilities. The need for additional research on the stability of speech perception abilities in the older adult CI population was evident. Abstract 2- Introduction: Auditory deprivation occurs when the auditory system is deprived of sound, resulting in an inability to process auditory information over time. Individuals with untreated hearing loss are susceptible to the negative consequences associated with auditory deprivation, regardless of the type and degree of hearing loss. Presentation: A young adult female patient with asymmetrical hearing loss since childhood and significant hearing health history presented to the clinic. She had a history of unsuccessful hearing aid use and had been without any form of amplification in either ear for approximately 11 years. Discussion: The implications of hearing loss can go unnoticed for years, especially when hearing-impaired people implement strategies to compensate for their hearing loss. Hearing aids will provide ample access to auditory signals to avoid late-onset auditory deprivation. Conclusion: Sufficient and consistent auditory stimulation is essential to avoid the implications of auditory deprivation
