Subjects: 0306 Physical Chemistry (incl. Structural)

description: The chemolithoautotrophic bacterium, Acidithiobacillus ferrooxidans, commonly occurs in acid mine drainage (AMD) environments where it is responsible for catalyzing the oxidation of pyrite and concomitant development of acidic conditions. This investigation reports on the growth of this bacterial species on the pyrite surface and in the aqueous phase at a pH close to 2 as well as the role of adsorbed lipid in preventing pyrite dissolution. Both acid washed pyrite and acid-washed pyrite coated with lipids were used as substrates in the studies. The choice of lipid, 1,2-bis(10, 12-tricosadiynoyl)-sn-Glycero-3-Phosphocholine lipid (23:2 Diyne PC), a phosphocholine lipid, was based on earlier work that showed that this lipid inhibits the abiotic oxidation rate of pyrite. Atomic force microscopy showed that under the experimental conditions used in this study, the lipid formed ∼4-20 nm layers on the mineral surface. Surface-bound lipid greatly suppresses the oxidation process catalyzed by A. ferrooxidans. This suppression continued for the duration of the experiments (25 days maximum). Analysis of the bacterial population on the pyrite surface and in solution over the course of the experiments suggested that the pyrite oxidation was dependent in large part on the fraction of bacteria bound to the pyrite surface. © 2006 Hao et al; licensee BioMed Central Ltd.

description: Chinese character style transfer is a very challenging problem because of the complexity of the glyph shapes or underlying structures and large numbers of existed characters, when comparing with English letters. Moreover, the handwriting of calligraphy masters has a more irregular stroke and is difficult to obtain in real-world scenarios. Recently, several GAN-based methods have been proposed for font synthesis, but some of them require numerous reference data and the other part of them have cumbersome preprocessing steps to divide the character into different parts to be learned and transferred separately. In this paper, we propose a simple but powerful end-to-end Chinese calligraphy font generation framework ZiGAN, which does not require any manual operation or redundant preprocessing to generate fine-grained target-style characters with few-shot references. To be specific, a few paired samples from different character styles are leveraged to attain a fine-grained correlation between structures underlying different glyphs. To capture valuable style knowledge in target and strengthen the coarse-grained understanding of character content, we utilize multiple unpaired samples to align the feature distributions belonging to different character styles. By doing so, only a few target Chinese calligraphy characters are needed to generated expected style transferred characters. Experiments demonstrate that our method has a state-of-the-art generalization ability in few-shot Chinese character style transfer.

description: We derive a new analytic solution of $(n+1)$-dimensional Brans-Dikce-Maxwell theory in the presence of a potential for the scalar field, by applying a conformal transformation to the dilaton gravity theory. These solutions describe topological charged black holes with unusual asymptotics. We obtain the conserved and thermodynamic quantities through the use of the Euclidean action method. We also study the thermodynamics of the solutions and verify that the conserved and thermodynamic quantities of the solutions satisfy the first law of black hole thermodynamics.

description: We consider distributed-order non-local fractional optimal control problems with controls taking values on a closed set and prove a strong necessary optimality condition of Pontryagin type. The possibility that admissible controls are subject to pointwise constraints is new and requires more sophisticated techniques to include a maximality condition. We start by proving results on continuity of solutions due to needle-like control perturbations. Then, we derive a differentiability result on the state solutions with respect to the perturbed trajectories. We end by stating and proving the Pontryagin maximum principle for distributed-order fractional optimal control problems, illustrating its applicability with an example.

Statistical Guarantees for Spectral Methods on Neighborhood Graphs

description: This thesis studies spectral methods on neighborhood graphs. These methods operate on point-cloud data.They form a neighborhood graph over this data, use the eigenvectors and eigenvalues of a graph Laplacianmatrix to map each point to a set of data-dependent features, then run a simple algorithm which uses thesefeatures to perform a downstream task. Such methods are very general, and can be used to solve many different learning problems. They are also flexible, in that the feature mapping adapts to the structure of the data. However, this generality and flexibility also makes it challenging to understand the theoretical properties of spectral methods.To understand these theoretical properties, we adopt the classical perspective of nonparametric statistics.We provide precise guarantees which establish that spectral methods on neighborhood graphs can effectively solve various statistical problems. Chapter 2 analyzes a local spectral clustering method, PPR clustering, and shows that it approximately recovers well-conditioned density clusters. Chapters 3 and 4 consider two methods for regression, Laplacian smoothing and Laplacian eigenmaps, and show that each method is minimax optimal under various data models. In Chapter 5, we discuss assorted other properties of these methods, which differentiate them from more classical nonparametric approaches.

description: The objective of vocational education is to provide any student with the necessary skills and knowledge that utilize [sic] the full potential of the student's abilities and provides the employer with an employee who is immediately productive with a minimum of retraining
The Vocational Education Act of 1963 was written to provide high-quality vocational training to people of all ages. The aim was to further opportunities for gainful employment and to satisfy needs, interests, and abilities. Between fiscal years 1963 and 1973, $2.5 billion was invested. The Manpower Development and Training Act's (MDTA) purpose was to assist in the development of youth and adults in depressed inner city and rural areas.
In fiscal year 1976, approximately 500,000 students will receive occupational oriented education through vocational education monies under cooperative education, special needs, and work study. The amount expended will approximate $3,005,000,000.
Planning clerical programs requires a realistic account of future employment trends and manpower needs which must be related to curriculum developments. Employment in clerical jobs is expected to grow considerably faster than total employment, rising to 17.3 million in 1980. The courses offered to the trainees must be relevant to present demands. The follow-up placement study is used in conjunction with the investigation into different applications as well as the frequency and the use of clerical skills. The results should provide MDTA instructors information to plan their teaching materials and methods to meet the standards of the occupational field for which students are trained.

description: According to unified schemes of Active Galactic Nuclei (AGN), the central engine is surrounded by dusty, optically thick clouds in a toroidal structure. We have recently developed a formalism that for the first time takes proper account of the clumpy nature of the AGN torus. We now provide a detailed report of our findings in a two-paper series. Here we present our general formalism for radiative transfer in clumpy media and construct its building blocks for the AGN problem -- the source functions of individual dusty clouds heated by the AGN radiation field. We show that a fundamental difference from smooth density distributions is that in a clumpy medium, a large range of dust temperatures coexist at the same distance from the radiation central source. This distinct property explains the low dust temperatures found close to the nucleus of NGC1068 in 10 \mic interferometric observations. We find that irrespective of the overall geometry, a clumpy dust distribution shows only moderate variation in its spectral energy distribution, and the 10\mic\ absorption feature is never deep. Furthermore, the X-ray attenuating column density is widely scattered around the column density that characterizes the IR emission. All of these properties are characteristic of AGN observations. The assembly of clouds into AGN tori and comparison with observations is presented in the companion paper.

Crustal structure near Explorer Ridge : ocean-bottom seismometer results parallel to Revere-Dellwood fracture zone
Creators: name: Cheung, Henry P. Y.
Publisher: name: University of British Columbia
Year: 2010

description: An 80 km seismic refraction line was recorded on an array of three ocean bottom seismometers located 5 km west of the northern tip of Explorer ridge and parallel to Revere-Dellwood fracture zone on the Pacific plate. One reversed and two split-spread profiles have been obtained. The combined use of rotated SV component and polarization filtered record sections enabled identification and timing of the refracted S-wave on most sections. The travel time - distance relation for both P and S waves is interpreted in the intercept time (tau) and ray parameter domain using the technique introduced by Bessonova et al. (1974). This enables application of tau inversion to give extremal bounds for velocity-depth curves. A linearized inversion technique is applied to give the smoothest velocity-depth profiles consistent with the travel time data. Amplitude analysis using disk ray theory synthetic seismograms further refine the P-wave velocity-depth models. The final P- and S-wave velocity-depth profiles show a general increase of velocity with depth and no distinct structural discontinuities. A normal oceanic crustal thickness of approximately 6.5 km and an anomalously low Pn velocity of 7.3 km sec⁻¹ are interpreted. The existence of an abnormally thick crust (8-10 km}., on the opposite side of the ridge in Explorer plate, determined in other studies, contrasts markedly with the results of this research. Such a contrast lends support to the proposal that the complex structure and thick crust are the result of compressive interaction between the young, small Explorer plate and the older, larger North America plate. Values of Poisson's ratio in the range of 0.25 to 0.32 are determined for the crustal material but better resolution of the velocity-depth profiles is required before a meaningful geological interpretation can be made.
A marine deep seismic sounding survey over Winona Basin
Creators: name: Thorleifson, Allan James
Publisher: name: University of British Columbia
Year: 2010

description: During the summer of 1975 a deep seismic sounding survey was carried out over Winona Basin, a deep water sedimentary basin located off the northern end of Vancouver Island. Three reversed refraction profiles were shot, one parallel and two perpendicular to the axis of the basin, with penetration from the ocean bottom to the upper mantle. Several sub-critical reflection profiles were also shot in an attempt to delineate the sedimentary structure of the basin. The two sub-critical reflection profiles shot over the central part of the basin were analyzed using the T²-X² method. The data sets gave layer velocities and thicknesses for 2 km of sediments for one of the profiles and .6 km for the other although petroleum industry data indicate that neither profile penetrated to the volcanic basement. The remaining reflection profiles were shot on the sides of the basin. On the western flank of Paul Revere Ridge, approximately 1 km of sediments with velocity in the range 2.5 to 3.5 km/s overlies volcanic basement. Over the continental slope on the east the seismic energy is strongly scattered below an upper 0.7 km of sediments. Refraction profile 75-1,1R, along the axis of the basin, was analyzed in a previous study using synthetic seismograms. However, the severe lateral inhomogeneities across the basin necessitated the use of ray tracing for the cross basin refraction profiles, 75-2,2R and 75-3,35. The final models are non-unique but they satisfy the seismic data very well and are consistent with profile 75-1,1R, gravity data and current views on plate tectonics. They show deep crustal layers dipping from both sides of the basin towards the center. Evidence for subduction as well as lateral motion between the Explorer and American plates has led to the conclusion that oblique subduction is occurring at Winona Basin.

description: We present and implement the concept of the Fourier-domain dedispersion (FDD) algorithm, a brute-force incoherent dedispersion algorithm. This algorithm corrects the frequency-dependent dispersion delays in the arrival time of radio emission from sources such as radio pulsars and fast radio bursts. Where traditional time-domain dedispersion algorithms correct time delays using time shifts, the FDD algorithm performs these shifts by applying phase rotations to the Fourier-transformed time-series data. Incoherent dedispersion to many trial dispersion measures (DMs) is compute, memory-bandwidth and I/O intensive and dedispersion algorithms have been implemented on Graphics Processing Units (GPUs) to achieve high computational performance. However, time-domain dedispersion algorithms have low arithmetic intensity and are therefore often memory-bandwidth limited. The FDD algorithm avoids this limitation and is compute limited, providing a path to exploit the potential of current and upcoming generations of GPUs. We implement the FDD algorithm as an extension of the DEDISP time-domain dedispersion software. We compare the performance and energy-to-completion of the FDD implementation using an NVIDIA Titan RTX GPU against the standard as well as an optimized version of DEDISP. The optimized implementation already provides a factor of 1.5 to 2 speedup at only 66% of the energy utilization compared to the original algorithm. We find that the FDD algorithm outperforms the optimized time-domain dedispersion algorithm by another 20% in performance and 5% in energy-to-completion when a large number of DMs (>=512) are required. The FDD algorithm provides additional performance improvements for FFT-based periodicity surveys of radio pulsars, as the FFT back to the time domain can be omitted. We expect that this computational performance gain will further improve in the future.

description: We analyse Gaia EDR3 parallax systematics as a function of magnitude and sky location using a recently published catalogue of 12,500 asteroseismic red-giant star distances. We selected ~ 3500 red clump (RC) stars of similar chemical composition as the optimal subsample for this purpose. We perform a detailed assessment of systematic uncertainties relevant for parallax offset estimation based on the asteroseismic distances. Following this assessment, we adopt for our baseline analysis the asteroseismic parameters measured as in Elsworth et al. (2020), spectroscopy from APOGEE (DR17), and we further restrict the sample to low-extinction RC stars with quality astrometric solutions from Gaia EDR3. We then investigated both the parallax offset relative to the published Gaia EDR3 parallaxes and the residual parallax offset after correcting Gaia EDR3 parallaxes following Lindegren et al. (2021).
 We find residual parallax offsets very close to zero (-1.6 +/- 0.5 (stat.) +/- 10 (syst.) muas) for stars fainter than G > 11 mag in the initial Kepler field. For 17 K2 campaigns in the same magnitude range, the residual parallax offset is +16.5 +/- 1.7 (stat.) +/- 10 (syst.) muas. At brighter magnitudes (G <= 11 mag), we find inconsistent residual parallax offsets between the Kepler field, 17 K2 campaigns, and the TESS southern continuous viewing zone, with differences of up to 60 muas. This suggests a significant dependence on sky location at bright magnitudes due to the lack of bright physical pairs available for determining the parallax offset corrections. Finally, we estimate the absolute magnitude of the RC and obtain M_Ks^RC = -1.650 +/- 0.025 mag in the 2MASS Ks-band and M_G^RC = (0.432 +/- 0.004) - (0.821 +/- 0.033) (Teff [K] - 4800K)/1000K [mag] in the Gaia G-band.

title: The Coal Conflict: Utah's Fight with the Union Pacific Railroad
Creators: name: Bishop, Michael Guy
Publisher: name: Utah State University
Year: 1976

description: The problem of an adequate fuel supply plagued the people of the Salt Lake Valley from the Mormons' earliest occupation of the region. The first type of fuel used in the area was timber from the surrounding mountains, but this proved to be insufficient to meet the demands of growing population. With the rapid increase in the number of homes and businesses in the Salt Lake area, a new source of fuel was needed. A universal feeling existed in the community that coal was the answer to its needs.
In the autumn of 1859 coal was discovered near the present-day town of Coalville, about fifty wagon-miles from Salt Lake City. The main deposits were on Chalk Creek in Summit County. Coal mines were opened immediately, and the coal was wagon-freighted to the fuel-short people of Salt Lake City and other Utah communities. This early method of transporting the coal by wagon failed to provide sufficient fuel to meet all demands, and a better way was sought,
In the spring of 1869, at Promontory Summit in the Utah Territory, an event occurred which not only marked the completion of a great achievement for the United States, but appeared to be the answer to the Mormons fuel needs as well. On May 10 the Union Pacific Railroad and the Central Pacific Railroad joined their tracks in a rather obscure ceremony at Promontory. Brigham Young, in his position as spiritual and temporal leader of the Mormons, saw this event as Providence's answer to the problem of shipping coal from the recently developed mines.

description: Background: Previously, a database characterizing examples of Embryophyte gene family lineages showing evidence of positive selection was reported. Of the gene family trees, 138 Embryophyte branches showed Ka/Ks≫1 and are candidates for functional adaptation. The database and these examples have now been studied in further detail to better understand the molecular basis for plant genome evolution. Results: Neutral modeling showed an excess of positive and/or negative selection in the database over a neutral expectation centered on the mean Ka/Ks ratio. Out of 673 families with assigned structures, 490 have at least one branch with Ka/Ks ≫1 in a region of the protein, enabling a picture of selective pressures delineated by protein structure. Most gene families allowed reconstruction back to the last common ancestor of flowering plants (Magnoliophytes) without saturation of 4- fold degenerate codon position. Positive selection occurred in a wide variety of gene families with different functions, including in the self incompatibility locus, in defense against pathogens, in embryogenesis, in cold acclimation, and in electrontransport. Structurally, selective pressures were similar between alpha-helices and beta- sheets, but were less negative and more variant on the surface and away from the hydrophobic core. Conclusion: Positive selection was detected statistically significantly in a small and nonrandom minority of gene families in a systematic analysis of embryophyte gene families. More sensitive methods increased the level of positive selection that was detected and presented a structural basis for the role of positive selection in plant genomes. © 2006 Roth and Liberles; licensee BioMed Central Ltd.

description: As society changes, current educational systems need to be evaluated and upgraded. Methods and procedures of teaching become outdated with constant technological advances. Predictions of the Bureau of Labor Statistics indicate, " ... more than 350,000 new clerical and related jobs will be added each year during the next decade."1 These projected workers will have to obtain training for their future careers. The business teacher has a responsibility to provide necessary training for students pursuing business careers.
How can these teachers prepare themselves to meet the needs of their students? An effective way for teachers to keep abreast of changes in educational philosophies is through additional schooling. However, Snelling states, "Further education is important and should have no limits, but the direction of that further education is what counts."
Teacher training institutions have a responsibility to keep their graduate programs relevant to the needs of business, society, and their students.
Teacher education institutions have the responsibility of providing both prospective and current business educators with the opportunity to develop the flexibility needed to cope with the challenges of the Future.
Conducting a follow-up study of graduates can provide valuable information to assure graduate programs are meeting the needs of modern business and society .

description: Despite the use of highly active antiretroviral therapy (HAART), neuronal cell death remains a problem that is frequently found in the brains of HIV-1-infected patients. HAART has successfully prevented many of the former end-stage complications of AIDS, however, with increased survival times, the prevalence of minor HIV-1 associated cognitive impairment appears to be rising among AIDS patients. Further, HIV-1 associated dementia (HAD) is still prevalent in treated patients as well as attenuated forms of HAD and CNS opportunistic disorders. HIV-associated cognitive impairment correlates with the increased presence in the CNS of activated, though not necessarily HIV-1-infected, microglia and CNS macrophages. This suggests that indirect mechanisms of neuronal injury and loss/death occur in HIV/AIDS as a basis for dementia since neurons are not themselves productively infected by HIV-1. In this review, we discussed the symptoms and causes leading to HAD. Outcome from this review will provide new information regarding mechanisms of neuronal loss in AIDS patients. © 2006 Ghafouri et al; licensee BioMed Central Ltd.

description: Background: Activation of naïve B lymphocytes by extracellular ligands, e.g. antigen, lipopolysaccharide (LPS) and CD40 ligand, induces a combination of common and ligand-specific phenotypic changes through complex signal transduction pathways. For example, although all three of these ligands induce proliferation, only stimulation through the B cell antigen receptor (BCR) induces apoptosis in resting splenic B cells. In order to define the common and unique biological responses to ligand stimulation, we compared the gene expression changes induced in normal primary B cells by a panel of ligands using cDNA microarrays and a statistical approach, CLASSIFI (Cluster Assignment for Biological Inference), which identifies significant co-clustering of genes with similar Gene Ontology™ annotation. Results: CLASSIFI analysis revealed an overrepresentation of genes involved in ion and vesicle transport, including multiple components of the proton pump, in the BCR-specific gene cluster, suggesting that activation of antigen processing and presentation pathways is a major biological response to antigen receptor stimulation. Proton pump components that were not included in the initial microarray data set were also upregulated in response to BCR stimulation in follow up experiments. MHC Class II expression was found to be maintained specifically in response to BCR stimulation. Furthermore, ligand-specific internalization of the BCR, a first step in B cell antigen processing and presentation, was demonstrated. Conclusion: These observations provide experimental validation of the computational approach implemented in CLASSIFI, demonstrating that CLASSIFI-based gene expression cluster analysis is an effective data mining tool to identify biological processes that correlate with the experimental conditional variables. Furthermore, this analysis has identified at least thirty-eight candidate components of the B cell antigen processing and presentation pathway and sets the stage for future studies focused on a better understanding of the components involved in and unique to B cell antigen processing and presentation. © 2006 Lee et al; licensee BioMed Central Ltd.

title: A Study to Determine what Businessmen in Logan know about the Cooperative Office Education Concept
Creators: name: Patz, Penelope
Publisher: name: Utah State University
Year: 1976

description: The first program of cooperative education was established in 1906, and by 1942 there were thirty programs in the country. During World War II, all cooperative programs were stopped in the interest of getting people through school as quickly as possible. When programs were resumed after the war, the pace picked up some, going from 26 programs in 1946 to 130 programs in 1968 (Ferris, 1969, p. 480).
The primary objective of cooperative vocational education is to turn out skilled, responsible young adults who upon graduation from high school can assume a productive place in our technical society. A successful cooperative program relieves the employer of some of his training problems, and in addition, gives him the satisfaction of rendering an important service to the community (Huffman, 1969, p. 17).
The Advisory Council on Vocational Education established to evaluate implementation of the Vocational Education Act of 1963 stated, "Cooperative Education had the best record of all vocational programs in terms of the proportions of students placed in the occupation for which they were trained" (Evans, 1969, p. 17). Typical research studies show that more than 80 per cent of the graduates are so placed (Evans, 1969, p. 19).
Marion B. Folsom, former Secretary of Health, Education and Welfare stated:
Our basic objective . . . is to increase the supply of workers qualified to fill the jobs for which there will be a demand as the economy expands and to reduce the number qualified for unskilled jobs. (Bolger, 1964, p. 28)
The growth of our economy indicates that more and better workers will be needed in the future. Even though school training is valuable for a particular job, actual experience on the job sometimes is the only way to develop the necessary competence . Cooperative education programs are designed to bridge the gap between the school and the business community. In this type of program, the student gains a first- hand knowledge of how a business operates (Raines, 1967, p. 303).
Are Logan businessmen aware of the cooperative office education programs available to them?
Because it has been unsung, people who have not been in direct contact with cooperative education have had little chance to learn much about it. Some confuse it with work-study; others have never heard of it (Ferris, 1969, p. 480).
This study will be a community survey to discover if businessmen know about the cooperative office education program and if they are willing and able to cooperate with the schools in providing work experience for high school students.

description: Dark energy must cluster in order to be consistent with the equivalence principle. The background evolution can be effectively modelled by either a scalar field or by a barotropic fluid.The fluid model can be used to emulate perturbations in a scalar field model of dark energy, though this model breaks down at large scales. In this paper we study evolution of dark energy perturbations in canonical scalar field models: the classes of thawing and freezing models.The dark energy equation of state evolves differently in these classes.In freezing models, the equation of state deviates from that of a cosmological constant at early times.For thawing models, the dark energy equation of state remains near that of the cosmological constant at early times and begins to deviate from it only at late times.Since the dark energy equation of state evolves differently in these classes,the dark energy perturbations too evolve differently. In freezing models, since the equation of state deviates from that of a cosmological constant at early times, there is a significant difference in evolution of matter perturbations from those in the cosmological constant model.In comparison, matter perturbations in thawing models differ from the cosmological constant only at late times. This difference provides an additional handle to distinguish between these classes of models and this difference should manifest itself in the ISW effect.

A sizable snowfall, particularly in the Uintah Mountains, makes Utah's major contribution to the water flow of the Colorado River. During the spring runoff the melting snow finds its way to the Colorado River, which eventually empties into the Gulf of Mexico. In large measure this water has held, and still holds, the key to Utah's development.
Because Utah lies in an arid region, water is an extremely important resource. Upon arrival to the Great Basin in 1847, the Mormon pioneers immediately set about solving the problem of diverting water from the streams of the area onto land. This was necessary to raise crops needed for their survival. Thus was begun the development of irrigation which along with being of extreme necessity became an important tradition in Utah.
As the population of the Great Basin continued to rise, it was found that demands on easily accessible water became too great for the existing supply. Cost was the greatest problem facing Utah's people in developing the potential of more inaccessible waters. Even with the formation of cooperative companies much of the water could not be utilized . The largest potential water source of all was the Colorado River Basin. But separating the larger population of the Great Basin from that water were the Wasatch Mountains. Use of this water would necessitate diversion of it through tunnels from one Basin to the other, a much too costly venture to be attempted privately. Those people who eventually settled in the Colorado Basin itself dount that natural stream flow was not sufficient to meet t he needs of everyone.

description: The city of Tientsin is situated in northern China at the junction of the Peiho (River) and the Yuho (the Grand Canal). Its latitude is approximately 39 degrees north with a longitude of about 117 degrees east. The unique thing about Tientsin in 1900 was that it was actually two totally separate cities. Tientsin City , or the Native City, was surrounded by a large wall built in 1405. The wall was about thirty feet thick and about twenty-five feet high. The sides of it were faced with brick work four to five feet thick and the center was filled with dirt . A brick parapet about five feet high capped the wall, and gates were situated in the center of each side. Over these gates and in the four corners were built two storied buildings which served as look-out stations and added a very ornamental effect. Buildings inside the Native City were very close together. The streets were narrow, and transit and public utilities were very poor. Outside the walls of the Native City were extensive suburbs in which a large part of the native population lived. Surrounding the suburbs of the Native City was a mud wall which had been construct ed in 1858 as a defense against foreigners.

description: Transport through spin-blockaded quantum dots provides a means for electrical control and detection of nuclear spin dynamics in the host material. Although such experiments have become increasingly popular in recent years, interpretation of their results in terms of the underlying nuclear spin dynamics remains challenging. Here we point out a fundamental process in which nuclear spin dynamics can be driven by electron shot noise; fast electric current fluctuations generate much slower nuclear polarization dynamics, which in turn affect electron dynamics via the Overhauser field. The resulting extremely slow intermittent current fluctuations account for a variety of observed phenomena that were not previously understood.

description: As mass merchandising has become an important part of our American way of life and as competition has increased, marketers have recognized the need for a positive public image. Many retail store managers are now evaluating all inside selling activities to determine locations within the store that contribute to improved customer relations. The checkout station is considered one of the best areas for effective customer relations since the checker-cashier is of~en the only employee the customer contacts while shopping and since all customers must leave through the checkout area in many stores. Retail store managers recognize the need f or efficient, courteous checker-cashiers and seek persons who a re trained in merchandise checking and customer relations (d).
In 1968, the Supermarket Institute-National Cash Register Cashier-Checker Training program was initiated at Weber State College. At first , the program was offered as a night class during three of the four school quarters . In the past six years this course enrollment has grown enormously , from three classes per year to 8-12 classes per year. The facilities no"' permit enrollments of 30-40 students where only 20 students were permitted to participate in each training session.
In 1973 Weber State College decided to offer this course to high school students. Weber County District sent 40 students during the first quarter and Ogden City District sent 30 students. The students received release time from the school to go to the college from 7:30 a.m. to 9:30 a.m. each day for six weeks of the quarter. At present, Weber State is setting up an articulated program where high school students will take the self-study package of learning and complete it at their high schools, and the balance of the time will be used in the specialized lab at Weber State, using the equipment in the lab (10).
In an interview with Dan Litchford, the acting department chairman, he stated, "There have been studies to evaluate and improve the course since it was first started . Most of the studies were to identify the need for graduates who have completed the SMI- NCR course" (10). This proposed study is the first to include evaluation of student performance on the job.
More specifically this study was designed to accomplish the following objectives :
1. To identify present employers of the graduates.
2. To obtain supervisor's evaluations of graduates proficiency with respect to:
a. Operation of cash register
b. Handling of checks
c. Making correct change
d. Handling food stamps
e. Handling merchandise adjustments
f. Weighing produce on scales
g. Stocking
h. Bagging
A method for simulating and representing strong ground motion

description: A method for representing and synthesizing strong motion accelerograms is proposed in this thesis. The procedure models an acceleration time-history as a non-stationary second order autoregressive (AR) process. Three AR parameters are determined from the data in a time-adaptive manner. They provide a quantitative description of the time-varying spectral content of the recording. The AB parameters may also be utilized as prediction filter coefficients, enabling one to generate a suite of artificial accelerograms, each having the same time-dependent spectral content as the target record. The simulated time-histories may be used for computing structural response in earthquake-prone areas. This analysis has been extended to include a number of recordings obtained during earthquakes of various magnitudes (M) at a variety of epicentral distances (D). As a result, 'type curves' representing the empirical behaviour of the three AB parameters have been determined. Although incomplete, this information may be used to generate artificial accelerograms for arbitrary combinations of M and D.

description: Context. Dust in active galactic nuclei is clearly present right outside the broad-line region (BLR) in the form of a dusty molecular torus. However, some models of the BLR predict that dust may also exist within the BLR. Aims. We study the reprocessing of radiation by the BLR with the aim of observing how the presence of dust affects the reprocessed continuum and the line properties. Methods. We calculated a range of models using the CLOUDY photoionisation code for dusty and dustless plasma. We paid particular attention to the well-studied object NGC 5548, and we compared the line equivalent width predictions with the data from observations for this object. Results. We obtained a rough agreement between the expected equivalent widths of the H$β$ and Mg II lines and the observed values for NGC 5548 for the line distances implied by the time-delay measurement (for H$β)$ and the radius-luminosity relation (for Mg II) when the medium is dusty. We found the incident radiation to be consistent with the radiation seen by the observer, so no shielding between the inner disc and the BLR is required. High ionisation lines such as He II, however, clearly form in the inner dustless region. When the additional absorber is present, the H$β$ emitting region moves closer to the dustless part of the accretion disc surface.

title: A Manpower Study of the Utah Feed, Grain, and Seed Industry and the Idaho Seed Industry

description: As the farmers of Utah and the nation become more highly trained and more efficient in adapting new technological knowledge in their farming enterprises, farms increase in size and the number of workers needed to produce food for our state and nation decreases. A concurrent yet opposite change occurs in those businesses which perform services for farmers or which market, process, and distribute the farmer's product. Farmers are demanding more skilled services while consumers are demanding that the farms' products receive more processing and distribution services which must be performed off the farm. We, thus, have a growing network of enterprises to perform these services for the farmer. The term, off-farm agricultural business, has become generally accepted as the designation for these companies .
Many of the workers in these off-farm agricultural businesses need knowledge and skill in agriculture for success in their jobs . For example, the feed, grain, and seed industry requires various levels of competency of agricultural knowledge and skill. This study should point out to Utah vocational agricultural educators whether or not they should begin a more concerted effort to teach the competencies needed by the employees of the feed, grain, and seed industry. From the observations of the writer the needed levels of competency of the feed, grain, and seed industry have not been an important part of most vocational agriculture curricula in Utah. It is a major purpose of this study to provide job titles and manpower demand information to enable a study to be performed of the competencies necessary for employment in the feed, grain, and seed industry.
