description: We present first results from an unbiased 50 deg^2 submillimeter Galactic survey at 250, 350, and 500 micron from the 2006 flight of the Balloon-borne Large Aperture Submillimeter Telescope (BLAST). The map has resolution ranging from 36 arcsec to 60 arcsec in the three submillimeter bands spanning the thermal emission peak of cold starless cores. We determine the temperature, luminosity, and mass of more than one thousand compact sources in a range of evolutionary stages and an unbiased statistical characterization of the population. From comparison with C^(18)O data, we find the dust opacity per gas mass, kappa r = 0.16 cm^2 g^(-1) at 250 micron, for cold clumps. We find that 2% of the mass of the molecular gas over this diverse region is in cores colder than 14 K, and that the mass function for these cold cores is consistent with a power law with index alpha = -3.22 +/- 0.14 over the mass range 14 M_sun < M < 80 M_sun. Additionally, we infer a mass-dependent cold core lifetime of t_c(M) = 4E6 (M/20 M_sun)^(-0.9) years - longer than what has been found in previous surveys of either low or high mass cores, and significantly longer than free fall or likely turbulent decay times. This implies some form of non-thermal support for cold cores during this early stage of star formation.

description: At zero density, the `t Hooft large N_c limit often provides some very useful qualitative insights into the non-perturbative physics of QCD. However, it is known that at high densities the `t Hooft large N_c world looks very different from the N_c=3 world, which is believed to be in a color superconducting phase at high densities. At large N_c, on the other hand, the DGR instability causes a chiral-density wave phase to dominate over the color superconducting phase. There is an alternative large N_c limit, with the quarks transforming in the two-index antisymmetric representation of the gauge group, which at N_c=3 reduces to QCD but looks quite different at large N_c. We show that in this alternative large N_c limit, the DGR instability does not occur, so that it may be plausible that the ground state of high-density quark matter is a color superconductor even when N_c is large. This revives the hope that a large N_c approximation might be useful for getting some insights into the high-density phenomenology of QCD.

title: The Development of Career Exploration Work Simulation Units for Career Education in Grades Seven Through Nine
Creators: name: Manwill, Gerald Eldon
Publisher: name: Utah State University
Year: 1974

description: The purpose of this study was to (1) select six vocational areas for Career Exploration Work Simulation Units development, hereafter referred to as CEWSU (2) design mock-up sites for CEWSU construction, (3) specify materials to be used in the mock-up, (4) describe tasks to be completed in the simulation exercises, (5) construct six CEWSU simulation units for placement in junior high school career education programs, (6) gather materials and tools to be used in each of the six CEWSU, (7) develop and program cassette tape instructions and flip charts for the CEWSU, (8) field test the CEWSU, (9) revise the CEWSU according to field test results, (10) publish replicable plans for the construction and operation of each CEWSU.
The ultimate goal of this project was to design and develop a product for u s e in the public school system. For the final product to be considered effective it had to meet various criteria. The criteria were as follows:

The CEWSU had to be self-instructional.
The CEWSU had to provide a hands-on experience.
The CEWSU had to provide the experience in a short period of time.
The CEWSU had to be inexpensive to operate.
The CEWSU had to be readily available to youth.
The CEWSU had to simulate an actual work experience.

The implications from the results indicated that:

Not all of the criteria listed above were met by all of the CEWSU.

The CEWSU developed in the present study should be reprogrammed for use with the developmentally disabled child.

Many more CEWSU, for career exploration, should be designed and developed in other vocational areas than those covered in the present project.
Studies on the granulocyte cell surface oxidase.
Creators: name: Dewar, Catharine Lynne
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examined the possible role of the microfilaments and microtubules in controlling the activity of the granulocyte plasma membrane oxidase. There have not been any detailed investigations of this topic published to date. The conflicting literature on the nucleotide specificity and location of the oxidase within the granulocyte was examined. In vitro techniques for isolating granulocytes from human peripheral blood and for quantitating the initial rate of plasma membrane oxidase activity were developed and used for these investigations. The involvement of microfilaments and microtubules in oxidase activity was studied by using pharmacological agents known to disrupt these structures in vitro (cytochalasin B, and colchicine, vinblastine and vincristine, respectively). Control experiments were also performed to ensure that microfilament and microtubule disruption by these agents provided the best explanation for the results presented herein. Correlative experiments were conducted to determine if a change in hexose monophosphate shunt activity was associated with the observed changes in plasma membrane oxidase activity brought about by the drug treatments. Experiments on non-phagocytic granulocytes showed that microfilament disruption led to enhanced oxidase activity, while microtubule disruption produced a dual effect : a paradoxical enhancement (with low doses or brief exposures to the agents) and an impairment in oxidase activity. These results suggested that microfilaments act as a constraint against, while microtubules are required for plasma membrane oxidase activity. The requirement for microtubules was highlighted in experiments where the usual enhancement in oxidase activity with cytochalasin B was ablated when the granulocytes were concomitantly incubated with a microtubule-disrupting agent. (With phagocytic granulocytes qualitatively similar results were observed. However, those experiments were not suitable for studying cell surface oxidase activity because the presence of ingestable. Particles made it impossible to determine whether plasma membrane and/or granule oxidase activity was being measured.) Based on the spectrophotometric and electron microscopic results presented and the relevant findings from other investigators, a scheme concerning the participation of the cytoskeletal elements in granulocyte plasma membrane oxidase activity was devised. In this scheme the microfilaments physically constrain the oxidase within the plasma membrane, and thereby hold the activity of the oxidase in check. Thus, microfilament disruption is envisaged to result in enhanced oxidase activity by freeing the enzyme. However, the oxidase is viewed as optimally active only as long as the microtubules are present to maintain the plasma membrane topography suitable for the enzyme's activity.
An Historical Assessment of the Narrative Uses of the Words "Kabbalah," "Cabala," and "Qabala/h": Discerning the Differences for Theological Libraries

description: Terminology surrounding the subject of "Kabbalah" has long been notoriously inconsistent and complex. What limited scholarly attention has been devoted to this quandary has in some cases served only to increase the confusion, resulting in significant problems for cataloging and for reference services. This essay explores the background of variant orthographies, including origins, definitions, and usages, and considers the implications of this inconsistency for libraries. A bibliography of pertinent literature is included.
Behavioral and Physiological Indicators of Cephalopod State, Perceptions, and Welfare

description: Cephalopods are behaviorally complex invertebrates, commonly kept in laboratories and public aquariums. My dissertation describes different means to measure changes in behavior and physiology of these incredible animals. First, I created two different designs of artificial patches to measure foraging intensity of the giant Pacific octopus, Enteroctopus dolfeini, in Prince William Sound, Alaska. I was able to measure differences in foraging between habitat types and locations. Next, I validated a minimally invasive technique to measure stress hormones in three species of cephalopods commonly kept in captivity, Sepia bandensis, Euprymna berryi, and Octopus chierchiae. I was able to measure changes in glucocorticoids, cortisol and corticosterone in all three species after an ACTH challenge and was the first instance where changes of cortisol was measured in a cephalopod. This technique was then used to measure changes in stress and reproductive hormones in reproductive and senescent Octopus bimaculoides after a stress test. In this experiment, I was able to measure changes in estradiol, progesterone, and testosterone from both age classes. This experiment also further validates cortisol to be the stress hormone that best describes changes in glucocorticoid production due to stress. Finally, I used observations of Octopus tetricus in Jervis Bay, Australia to describe contest behavior. By being able to reidentify individuals due to scars and injuries I was able to show that octopuses display similar behavior when participating in multiple contests. Furthermore, I describe the posture and coloration used in these contests which may be used to communicate. My hope is that my dissertation will provide insights of wild cephalopod behavior along with providing a technique to improve welfare in captivity.

description: The use of atomic decay rates as a probe of sub-vacuum phenomena will be studied. Because electromagnetic vacuum fluctuations are essential for radiative decay of excited atomic states, decay rates can serve as a measure of the suppression of vacuum fluctuation in non-classical states, such as squeezed vacuum states. In such states the renormalized expectation value of the square of the electric field or the energy density can be periodically negative, representing suppression of vacuum fluctuations. We explore the extent to which atomic decays can be used to measure the mean squared electric field or energy density. We consider a scheme in which atoms in an excited state transit a closed cavity whose lowest mode contains photons in a non-classical state. The change in the decay probability of the atom in the cavity due to the non-classical state can, under certain circumstances, serve as a measure of the mean squared electric field or energy density in the cavity. We derive a quantum inequality bound on the decrease in this probability. We also show that the decrease in decay rate can sometimes be a measure of negative energy density or negative squared electric field. We make some estimates of the magnitude of this effect, which indicate that an experimental test might be possible.

Study on growth, development and some biochemical aspects of several varieties of Nerine
Creators: name: Dewi, Kumala
Publisher: name: University Of Tasmania

description: Nerine fothergillii bulbs were stored at different temperatures for a certain period of time and then planted and grown in an open condition. The effect of the different storage temperatures on carbohydrate content and endogenous gibberellins was examined in relation to flowering. Flowering percentage and flower number in each umbel was reduced when the bulbs were stored at 30o C while bulbs which received 5o C treatment possess earlier flowering and longer flower stalksthan bulbs without 5o C storage treatment. Carbohydrates in both outer and inner scales of N. fothergillii were examined semi-quantitatively by paper chromatography. Glucose, fructose and sucrose have been identified from paper chromatogramS. Endogenous gibberellins in N. fothergillii have been identified by GC - SIM and full mass spectra from GCMS. These include GA19, GA20 and G Al, their presence suggests the occurence of the early 13 - hydroxylation pathway. The response of N. bowdenii grown under Long Day (LD) and Short Day (SD) conditions was studied. Ten plants from each treatment were examined at intervals of 4 weeks. Photo\\ period did not affect the growth and development of N. bowdenii but it influenced the flowering time. SD conditions gives earlier flowering than LD condition. Anthocyanins in Nerine have been examined using paper chromatography. The solvents used were BAW and MAW. Five major anthocyanins (pelargonidin, cyanidin, delphinidin, malvidin and peonidin) have been identified from several varieties of Nerine .
title: The Effects of Awareness on Generalization and Incubation
Creators: name: Lyon, Edward R.
Publisher: name: Utah State University
Year: 1974

description: The purpose of this study is to demonstrate the effects of awareness on experimentally induced anxiety. Forty college undergraduates were conditioned with a mild electric shock as the UCS (unconditioned stimulus) and a tone a s the CS (conditioned stimulus). After conditioning, the experimental group was taught to discriminate between the CS and six other tones which were both higher and lower in frequency than the CS. The control group was not given these learning trials. After learning to discriminate the tones, the experimental subjects had a higher GSR (Galvanic Skin Response) to the seven tones as compared to the control group. The discrimination process thus facilitated an association among the tones. This increase in anxiety was relatively greater with the passage of time as the experimental subjects also had a higher GSR to the seven tones 24 hours after conditioning compared with 30 minutes after conditioning. These increases, however, were not significant in all cases.

description: We detect correlations in the cosmic far-infrared background due to the clustering of star-forming galaxies in observations made with the Balloon-borne Large Aperture Submillimeter Telescope, BLAST, at 250, 350, and 500 microns. We perform jackknife and other tests to confirm the reality of the signal. The measured correlations are well fit by a power law over scales of 5-25 arcminutes, with Delta I/I = 15.1 +/- 1.7%. We adopt a specific model for submillimeter sources in which the contribution to clustering comes from sources in the redshift ranges 1.3 <= z <= 2.2, 1.5 <= z <= 2.7, and 1.7 <= z <= 3.2, at 250, 350, and 500 microns, respectively. With these distributions, our measurement of the power spectrum, P(k_theta), corresponds to linear bias parameters, b = 3.8 +/- 0.6, 3.9 +/- 0.6 and 4.4 +/- 0.7, respectively. We further interpret the results in terms of the halo model, and find that at the smaller scales, the simplest halo model fails to fit our results. One way to improve the fit is to increase the radius at which dark matter halos are artificially truncated in the model, which is equivalent to having some star-forming galaxies at z >= 1 located in the outskirts of groups and clusters. In the context of this model we find a minimum halo mass required to host a galaxy is log (M_min / M_sun) = 11.5 (+0.4/-0.1), and we derive effective biases $b_eff = 2.2 +/- 0.2, 2.4 +/- 0.2, and 2.6 +/- 0.2, and effective masses log (M_eff / M_sun) = 12.9 +/- 0.3, 12.8 +/- 0.2, and 12.7 +/- 0.2, at 250, 350, and 500 microns, corresponding to spatial correlation lengths of r_0 = 4.9, 5.0, and 5.2 +/- 0.7 h^-1 Mpc, respectively. Finally, we discuss implications for clustering measurement strategies with Herschel and Planck.

description: Identifying locations for secure sequestration of CO2 in geological formations is one of our most pressing global scientific problems. Injection into basalt formations provides unique and significant advantages over other potential geological storage options, including large potential storage volumes and permanent fixation of carbon by mineralization. The Central Atlantic Magmatic Province basalt flows along the eastern seaboard of the United States may provide large and secure storage reservoirs both onshore and offshore. Sites in the South Georgia basin, the New York Bight basin, and the Sandy Hook basin offer promising basalt-hosted reservoirs with considerable potential for CO2 sequestration due to their proximity to major metropolitan centers, and thus to large industrial sources for CO2. Onshore sites are suggested for cost-effective characterization studies of these reservoirs, although offshore sites may offer larger potential capacity and additional long-term advantages for safe and secure CO2 sequestration.
The Community of the Sisters of the Church : an exploration of their foundations and their early struggles following their arrival in Australia in 1892

Publisher: name: University Of Tasmania

description: For a school which in 1994 has over one thousand students, a full time staff of over seventy and a reputation as one of the best schools not only in Tasmania, but also in Australia, the opening day of St. Michael's Collegiate School over 100 years ago on Monday 3rd October 1892 was very low key. There was no formal opening by the Governor of Tasmania. There was no Bishop. No fanfare in the local press announced the new school. No reporter from The Mercury came to write up the event for Tuesday's paper. Twelve students were brought to the new school in Harrington Street (now the offices of Murdoch Clarke & Drake Solicitors and Barristers). There the twelve first enrolments were received by Sister Phyllis, Sister Hannah and Sister May of The Community of the Sisters of the Church which had founded the School, under the name of a \Higher Grade Elementary School\" as it was then called. The Dean Dean Dundas read prayers and to misquote T.S. Elliot Collegiate was born not with a bang but a whisper. Lack of a \"Grand Opening\" did not spell lack of strong support. Many people prayed for its success. Naturally the school had loomed large in the devotions of those three Sisters and the other four who had sailed from England. The other four Sisters (Bridget Lucy Irene and Rose) had gone on to Melbourne and Adelaide to work for the Order there and also found schools. No one prayed for the school more earnestly than Mother Emily Ayckbowm the foundress of both the Church Extension Association (C.E.A.) in 1864 and the Community of the Sisters of the Church in 1870; the secular and the spiritual arms of her efforts to spread Christ's messages to rich and poor. BUT - Who was Emily Ayckbowm? What was the Community of the Sisters of the Church? Who brought these Sisters to Australia? What was their work to be?"

In this paper we extend that method in order to obtain more general target states, working, for concreteness, with a system of two interacting electrons confined in semiconductor double quantum wells. Namely, we have shown that the same basic method can be employed to obtain localization, entanglement, and general superpositions of eigenstates of the system.

Creators: name: Reamsbottom, Stanley Baily
Publisher: name: University of British Columbia
Year: 2011

description: The metamorphic rocks of the Breakenridge and Cairn Needle Formations are correlated with the Upper Paleozoic and Mesozoic (Jurassic) strata respectively. Those of the Chilliwack Group - Peninsula Formation range in age from Upper Paleozoic to Lower Cretaceous. A gneissic granodiorite on Mount Breakenridge is cored by a younger (Early Tertiary) porphyritic quartz diorite. The Scuzzy granodiorite (Upper Cretaceous) is the main plutonic rock of the area. Between the Jurassic and Mid-Cretaceous the formations were folded into northwest trending antiforms and synforms. Three phases of folding are recognised. Major faults were produced in Mid-Cretaceous time. Contemporaneous with the folding the rocks were migmatized and regionally metamorphosed to form a kyanite-sillimanite facies series in which the metamorphic grade increases rapidly from South to North. The mineral assemblages in pelitic gneisses are considered to have approached equilibrium. The bulk composition of these gneisses may not only have controlled the presence of staurolite but also, through the opaque minerals present, the fs₂,fo₂ of the coexisting fluid phase. Extreme gradients in fluid phase composition (X CO₂) are demonstrated to have existed during the metamorphism of closely associated calc - silicate and dolomitic limestone. An episode of contact metatnorphism, which produced andalusite and sillimanite bearing schists was associated with the emplacement of the Scuzzy fluton. (U. Cretaceous).
Calibration of magnetic granulometric trends in oceanic basalts

Publisher: name: Columbia University
Year: 1999
Subjects: subject: Geophysics
subject: FOS: Earth and related environmental sciences

description: The validity of magnetic granulometric estimates relies heavily on the ability to distinguish ultrafine particles from coarser grains. For example, populations with dominantly superparamagnetic (SP) or multidomain (MD) grains both are characterized by low remanence and coercivity, and distinguishing these endmembers may provide valuable clues to the origin of magnetization in the intervening stable single domain (SD) size range. The natural grain size variations associated with variable cooling rates in submarine lavas provide a rare opportunity for examining progressive changes in average magnetic grain size, from SP–SD mixtures in submarine basaltic glass to SD–MD mixtures in flow interiors. Based on microanalysis and rock magnetic measurements on pillow basalt samples dredged from the flanks of the Mid-Atlantic Ridge (ages < 1 Ma to 70 Ma), a model of preferential dissolution with time of the finest-grained titanomagnetites has recently been suggested as the major process contributing to long-term temporal changes in remanent intensity of mid-ocean ridge basalts. We evaluated the local and long-term temporal trends in effective magnetic grain size predicted by this model using hysteresis data from a large number of submarine basalt samples which span a range of ages from ∼0 to ∼122 Ma. Specimens were systematically taken along transects perpendicular to the chilled margin of each sample. The large number of data (∼750 loops) and the inferred progressive change in grain size approaching the chilled margin allow recognition of mixing trends between MD and SD grains and between SD and SP grains on a Day-plot. These trends in hysteresis parameters are crucial to resolving the inherent, but frequently overlooked, ambiguity in inferring grain size from hysteresis parameters. We illustrate that two additional rock magnetic tests (warming of a low-temperature isothermal remanence and hysteresis loop shapes) often used to address these ambiguities are inconclusive, requiring some independent knowledge of whether SP or MD grains are likely to be present. Even with a considerably larger data set the substantial intrasample variability in oceanic basalts precludes recognition of any systematic trend in magnetic grain size with age.
The Effect of Tidal Stripping on Composite Stellar Populations in Dwarf Spheroidal Galaxies

description: We use N-body simulations to study the effects of tides on the kinematical structure of satellite galaxies orbiting a Milky Way-like potential. Our work is motivated by observations of dwarf spheroidal galaxies in the Local Group, for which often a distinction is possible between a cold centrally concentrated metal rich and a hot, extended metal poor population. We find that an important attenuation of the initial differences in the distribution of the two stellar components occurs for orbits with small pericentric radii (r_per < 20 kpc). This is mainly due to: i) the loss of the gravitational support provided by the dark matter component after tidal stripping takes place, which forces a re-configuration of the luminous components, and ii) tides preferentially affect the more extended stellar component, leading to a net decrease in its velocity dispersion as a response for the mass loss, which thus shrinks the kinematical gap. We apply these ideas to the Sculptor and Carina dwarf spheroidals. Differences in their orbits might help to explain, under the assumption of similar initial configurations, why in the former a clear kinematical separation between metal poor and metal rich stars is apparent, while in Carina this segregation is significantly more subtle.

The role of linear wave refraction in the transient eddy-mean flow response to tropical Pacific SST anomalies

description: The midlatitude response to tropical Pacific SST anomalies involves changes in transient eddy propagation, but the processes leading to the transient eddy changes are still not clear. In a recent study, we used a series of controlled general circulation model (GCM) experiments in which an imposed tropical Pacific sea-surface temperature (SST) anomaly is turned on abruptly and the response is analyzed in terms of its high- and low-frequency parts, to show that the changes in transient eddies induced by El Niño Southern Oscillation (ENSO) arise from changes in wave refraction on the altered mean flow. In this work, we use a quasi-geostrophic linear model and a linear stationary wave model, to interpret the GCM experiments and obtain the sequence of events that lead from a tropical SST anomaly to the quasi-equilibrium change in the mean and transient atmospheric circulation. The initial direct response of the mean flow is confined to the tropical and subtropical Pacific, similar to what is obtained from a stationary wave model. This tropical–subtropical mean flow change initiates a transient eddy response, which induces a midlatitude mean flow anomaly. The wave–mean flow system evolves towards a state in which the eddy anomalies maintain the mean flow anomalies, allowing them to persist. It is further shown that, while eddy momentum fluxes persistently accelerate and decelerate the subtropical and midlatitude mean flow, the eddy heat flux effect on the zonal mean flow is much more variable, and only marginally significant. The linear quasi-geostrophic model calculations capture the evolution of eddy momentum flux anomalies equatorwards of 60°N quite well, suggesting linear wave refraction can explain the midlatitude ENSO anomalies. However, other processes, like stationary waves or changes in the nonlinear stage of eddy life cycles, are needed to explain the ENSO-related anomalies at high latitudes, polewards of around 60°N.

Creators: name: Goodwin, Susan
Publisher: name: Utah State University
Year: 1974

description: Few studies in the area of psychodietetics have concentrated upon the relationship between a single dietary nutrient and behavior. However, some vitamins have been shown to be particularly important to central nervous system activity. Among these is Vitamin C (ascorbic acid).
Two experiments were done to determine the effects of ascorbic acid deficient diets on a learning task in which guinea pigs were subjects. Learning was defined as acquisition and extinction of shock-escape and shock-avoidance behavior.
In Experiment I, twelve adult guinea pigs were fed diets containing two different deficient amounts of ascorbic acid for six weeks. They were then run on shock-escape, shock-avoidance and extinction schedules. No significant differences in behavior among the dietary groups were shown by statistical analysis, either in acquisition or extinction.
In Experiment II, three adult guinea pigs were fed the same ascorbic acid-deficient diets as in Experiment I for six weeks after a baseline performance on a shuttlebox shock avoidance schedule was obtained. Performance after dietary treatment among or across subjects was not observably different from the performance prior to treatment.
Serum and adrenal protein analysis confirmed that the dietary treatment had lowered the total ascorbic acid content of the serum and adrenals, but behavior did not show a corresponding or consistent change.
These results indicate that ascorbic acid deficient diets fed to adult guinea pigs did not result in a change in behavior as observed on shock-escape, shock-avoidance, or extinction schedules.

description: Culture experiments with living planktic foraminifers reveal that the ratio of boron to calcium (B/Ca) in Orbulina universa increases from 56 to 92 μmol mol−1 when pH is raised from 7.61+/–0.02 to 8.67+/–0.03 (total scale). Across this pH range, the abundances of carbonate, bicarbonate, and borate ions also change (+530, −500, and +170 μmol kg−1, respectively). Thus specific carbonate system control(s) on B/Ca remain unclear, complicating interpretation of paleorecords. B/Ca in cultured O. universa also increases with salinity (55–72 μmol mol−1 from 29.9–35.4‰) and seawater boron concentration (62–899 μmol mol−1 from 4–40 ppm B), suggesting that these parameters may need to be taken into account for paleorecords spanning large salinity changes (~ 2‰) and for samples grown in seawater whose boron concentration ([B]SW) differs from modern by more than 0.25 ppm. While our results are consistent with the predominant incorporation of the charged borate species B(OH)4−into foraminiferal calcite, the behavior of the partition coefficient KD (defined as [B/Ca]calcite/[B(OH)4−/HCO3−]seawater) cannot be explained by borate incorporation alone, and suggests the involvement of other pH-sensitive ions such as CO3 2− For a given increase in seawater B(OH)4−, the corresponding increase in B/Ca is stronger when B(OH)4− is raised by increasing [B]SW than when it is raised by increasing pH. These results suggest that B incorporation controls should be reconsidered. Additional insight is gained from laser-ablation ICP-MS profiles, which reveal variable B/Ca distributions within individual shells.

description: In this paper we construct an effective field theory for a condensate of cold Fermi atoms whose scattering is controlled by a narrow Feshbach resonance. We show how, from first principles, it permits a hydrodynamic description of the BEC-BCS crossover from which the equation of state, intimately related to the speed of sound, can be derived. Specifically, we stress the non-universal behaviour of the equation of state at the unitary limit of infinite scattering length that arises when either, or both, of the range of the inter-atomic force and the scale of the molecular field become large.

description: PURPOSE BACKGROUND/SIGNIFICANCE: Although egg donation has occurred since the early 1980s, little is known about egg donors’ experiences, especially long-term outcomes. The purpose of this study was to explore the psychosocial and physical experiences of egg donors across the lifespan. The Biopsychosocial Model guided the research. METHOD: Participants were recruited from the Donor Sibling Registry list-serve and multiple Facebook groups targeting egg donors. The anonymous, online survey was developed using questions from previous egg donor surveys, validated measures of substance use and patient reported outcomes (CAGE-AID & PROMIS), and expert insight. Pretesting was completed with six egg donors. RESULTS: 363 participants (age range 22-71) donated an average of 3.3 times and the average time from initial donation to study participation was 13.75 years. Most donors (89.5%) had a positive experience. Yet, 41% reported pain (average pain score 6.7/10) directly related to the egg retrieval procedure, and 10.5% reported ovarian hyperstimulation syndrome. Anxiety (25.8%) and depression (23.2%) were the most common medical complications with 17% reporting emotional distress was a direct result of egg donation. Additionally, 11.5% of participants showed a clinically significant indication of drug and alcohol use (≥ 2 CAGE-AID). Changes to menstrual cycle, ovulation, or fertility occurred in 21% of participants post-donation. Most participants (94.3%) were not contacted by clinics for medical updates post-donation despite 25% having important medical changes to report. Most donors disclosed their donation to family and friends and felt pride, excitement, and joy in sharing. Fewer disclosed to their children. CONCLUSIONS: Egg donation experiences were positive despite reported pain, psychological impacts, and reproductive related concerns post-donation. Lack of clinical follow-up and patient desire to report post-donation medical concerns indicate a need for more post-procedure support and structured follow-up mechanisms. Clinical and regulatory policy changes should be considered. Practitioners can incorporate these findings when educating women who are considering donating eggs. Future research is needed to prospectively evaluate the prevalence of reproductive dysfunction, anxiety, depression, and drug/alcohol use, and disclosure to children and providers among egg donors.
title: Effects of Magnesium Deficiency on Discriminative Avoidance Behavior of Rats

description: The purpose of this thesis is to determine what effects a dietary magnesium deficiency has on the discriminative avoidance behavior of rats. Three experiments were conducted. Experiment I compared two groups to determine the effects of magnesium deficiency on bar-press discriminative avoidance behavior. The results of Experiment l clearly illustrated that rats fed n diet deficient in magnesium began to lose their discriminative avoidance behavior after approximately five days with a steady decrease in performance over the remaining five days. Experiment II used a single subject design in an attempt to replicate Experiment I and to determine whether or not the magnesium deficiency effect could be reversed. Blood samples of serum magnesium for each rat were taken daily. The results confirmed Experiment I. A magnesium deficiency did cause a decrease in the performance of discriminative bar-press avoidance. Two of the four rats responded to the rehabilitation treatment with a corresponding increase in avoidance behavior with an increase in serum magnesium levels. The other two rats did not recover avoidance performance with rehabilitation, but did improve with regard to other behavioral measurements. Experiment III again employed two groups of rats in an attempt to determine the effects of a magnesium deficiency upon acquisition of a discriminative shuttle box avoidance performance. A pilot study to Experiment III showed a clear effect with normal controls displaying statistically more avoidance responses than the experimentals who received subnormal levels of magnesium. The results from Experiment III however showed no statistically significant difference between the controls and experimentals even though there was a statistical difference in serum magnesium concentration.

description: Hot Jupiters are a class of extrasolar planet that orbit their parent stars at very short distances. Due to their close proximity, they are expected to be tidally locked, which can lead to a large temperature difference between their day and nightsides. Infrared observations of eclipsing systems have yielded dayside temperatures for a number of transiting planets. Furthermore the day-night contrast of the transiting extrasolar planet HD 189733b was mapped using infrared observations. It is expected that the contrast between the dayside and nightside of hot Jupiters is much higher at visual wavelengths as we move shortward of the peak emission, and could be further enhanced by reflected stellar light. Here we report on the analysis of optical photometric data of the transiting hot Jupiter CoRoT-1b, which cover 36 planetary orbits. The nightside hemisphere of the planet is consistent with being entirely black, with the dayside flux dominating the optical phase curve. This means that at optical wavelengths the planet's phase variation is just as we see it for the interior planets in our own solar system. The data allow only for a small fraction of reflected light, corresponding to a geometric albedo <0.20.

description: The purpose of this study was to see if there are any differences in how high and low self-disclosers score on the Holtzman Inkblot Technique. The study employed a causal-comparative design for descriptive purposes.
Two hundred four college students were given a self-disclosure inventory, and high and low self-disclosers were randomly selected from the highest and lowest interquartile ranges. The fifty subjects were administered the group version of the Holtzman Inkblot Technique.
The results indicated that female high self-disclosers scored significantly higher on Barrier and significantly lower on Hostility than female low self-disclosers.

description: We consider topological twisting of recently constructed Chern-Simons-matter theories in three dimensions with N=4 or higher supersymmetry. We enumerate physically inequivalent twistings for each N, and find two different twistings for N=4, one for N=5,6, and four for N=8. We construct the two types of N=4 topological theories, which we call A/B-models, in full detail. The A-model has been recently studied by Kapustin and Saulina. The B-model is new and it consists solely of a Chern-Simons term of a complex gauge field up to BRST-exact terms. We also compare the new theories with topological Yang-Mills theories and find some interesting connections. In particular, the A-model seems to offer a new perspective on Casson invariant and its relation to Rozansky-Witten theory.
