Teaching and Learning in Hard and Soft Disciplines at North American Universities
Creators: name: Osama, Ahmed

Publisher: name: The University of British Columbia
Year: 2016

description: In this study we employed National Student and Faculty Surveys of Student Engagement (NSSE and FSSE) from various USA and Canada universities to investigate teaching and learning practices in hard and soft disciplines. Using seven years of quantitative data extracted from the surveys, the trends of different teaching practices and learning outcomes in hard and soft disciplines were assessed. Also, we examined the association between the studied teaching practices and the resulting learning outcomes. Regression analysis was also performed to develop a model for the deep learning index. Results demonstrated that faculty in hard disciplines were more dependent on teacher-centered approaches than those in soft disciplines; the latter relied mainly on student-centered approaches. Moreover, student-centered approaches to teaching were found to have a positive impact on deep learning sub-scales, while teacher-centered approaches affected those sub-scales negatively.

Publisher: name: Utah State University
Year: 2021

description: The Scintillation Prediction Observation Research Task (SPORT) is a joint United States of America and Brazil 6U CubeSat mission. The US is providing the science instruments and the spacecraft launch. Brazil is providing the spacecraft bus, integration, and operations. Utah State University will provide four instruments for the mission as part of the US contribution in a suite called the Space Weather Probes (SWP). These instruments are the Sweeping Langmuir Probe (SLP), the Electric Field Probe (EFP), and the Sweeping Impedance Probe (SIP). Higher frequency components of the SLP and EFP will be observed through a Wave Spectrometer (WS). These instruments will provide measurements of electric fields, temperature, and density of ionospheric plasma. This thesis will describe the design, implementation, testing and calibration of the SLP, EFPs, and WS for the SPORT mission. A summary of results is also presented to show fulfillment of mission and instrumentation requirements.
Petrology of the Middle Cambrian Blacksmith Formation, North-Central Utah
Creators: name: Hay, Howard William
Publisher: name: Utah State University
Year: 1982

description: The dolostones and dolomitic limestones of the Middle Cambrian Blacksmith Formation were studied in the Bear River and Malad Ranges and the Wellsville Mountains of north-central Utah. The depositional textures and sedimentary structures retained within the rocks form the basis of subdivisions of measured sections, interpretation of depositional paleogeography, and reconstruction of environments.
Other studies of modern carbonate environments and their ancient analogues provided the basis for interpretation of the depositional textures found within the rocks of the Blacksmith Formation. Four identifiable lithofacies were recognized within the study area. These facies include: (1) oolite shoal; (2) restricted lagoon; (3) low- to middle-intertidal; and (4) high-intertidal to supratidal environments. These four facies have an areal distribution that was controlled by the interactions of: (1) vertical buildup of carbonate platform; fluctuation of sea level; and (3) subsidence.
The general environment of deposition is inferred to have been an isolated carbonate bank located in a marginal sea west of the craton. The carbonate bank was characterized by low-lying tidal flats surrounded by low- to middle-intertidal regions and a restricted lagoon, with oolite shoals forming a barrier that limited water movement on the bank.
Early diagenetic features include fibrous rim cement, fenestral fabric, and minor compaction. Secondary diagenetic changes are dominated by the dolomitization of most of the Blacksmith Formation within the study area.
Dolomitization is believed to result from downward reflux of hypersaline brines. The hypersaline brine formed in the intertidal and supratidal environments and percolated into the porous carbonate sediments. Due to the density of the brine, the descending brine displaced marine and other less dense pore waters. The dolomite distribution is in part due to facies control of the brine movement. Outward movement of the brine, and subsequent decrease in the Mg:Ca ratio, are also inferred to be controlling factors in the distribution and extent of the dolomitization.
Water Use and the Making of a New Socio-Natural Landscape

description: In the last decades of the nineteenth century, Rome was in a phase of transformation. In order to assume the role of cultural and political capital of the Kingdom of Italy, the city underwent a process of new urban infrastructure construction and demographic expansion. Rome’s demand for water increased as a result of this process, and measures initiated by the state, the urban authorities, and private sector agents consequently began to concentrate water resources from the city’s surroundings. The three main aims of these measures were to irrigate the countryside, to increase the quantity, quality, and coverage of the drinking water supply, and to meet the growing energy needs of the city. However, the social struggle about access to, distribution of, and use of the resource influenced the realisation of infrastructures and the utilization of water. As a result, the physical features and social role of the traditional landscape of Rome and its vast countryside began to change – in short, the area surrounding Rome underwent a process of urbanisation. Although such urbanisation was experienced by many European cities at the turn of the twentieth century, the case of Rome may shed light on how multifarious and sometimes contradictory the phenomenon was.

Application of Computational Fluid Dynamics to Determine Gas Expansion Factors of Differential Pressure Flow Meters
Creators: name: Campana, Patrick L.
Publisher: name: Utah State University
Year: 2021

description: The purpose of this research was to investigate if computer simulations could be used to accurately predict gas expansion in differential pressure flow meters. Differential pressure flow meters are used to measure the flow rate of pressurized liquids and gases through pipes. Computer simulations of liquid and gas flows were conducted for three distinct differential pressure flow meter geometries: Classical Venturis, Stand Concentric orifice plates, and wedge meters.
Gas flows were modeled as dry air using the assumption of a perfect gas. Expansion effects were modeled using the ideal gas law. Computer simulations of Classical Venturi and Standard Concentric orifice plates predicted gas expansion that matched existing laboratory data with remarkable accuracy. This indicates the computer simulation method, known as computational fluid dynamics, is an appropriate tool for determining gas expansion in differential pressure flow meters. Computer simulations of wedge meters were then conducted using the same modeling approach and produced reasonable gas expansion factor values.
Innovative Water Management Using Advanced Irrigation Systems and Biochar
Creators: name: Holt, Jonathan A.
Publisher: name: Utah State University
Year: 2021

description: Two approaches to water optimization in agriculture are to increase soil water retention and improve the efficiency of irrigation. A soil amendment that has received attention for its ability to increase soil water retention is biochar, the remaining biomass after high C materials have been pyrolyzed (burned with limited oxygen and heat). Two studies were conducted at a total of 10 site-years in Utah from 2018 to 2020 to evaluate how wood biochar influences the productivity and crop quality of irrigated alfalfa (Medicago Sativa L.), corn (Zea mays L.), and wheat (Triticum L.), along with soil water tension. One study included a single biochar rate of 22 Mg ha-1 at two irrigation levels (full vs. partial), where soil-incorporated biochar increased silage corn yield by 12% in 2018 and reduced yield by 10% in 2019. Top-dressed biochar had no impact on alfalfa yield from 2018-2020, in either irrigation rate. The other trial had six to seven biochar rates (0 – 67 Mg ha-1), plus the addition of wood chips at a single rate (22 Mg ha-1) at one site. This trial displayed a yield decrease of 0.01 Mg ha-1 of wheat grain for each additional Mg ha-1 of biochar applied, however there were no impacts on silage corn production. Data obtained over ten site years showed minimal impacts from biochar on crop yield, quality, or soil water tension, leading us to conclude that wood biochar was not an effective tool for enhancing crop production or conserving irrigation water in arid agriculture.
Most pivot sprinkler package in the Intermountain West are classified as mid-elevation sprinkler application (MESA). Several studies of low elevation spray application (LESA), low energy precision application (LEPA), and mobile drip irrigation (MDI) have demonstrated greater efficiency than MESA, due to less loss between the time that the irrigation water leaves the nozzle and enters the rootzone. However, these advanced sprinkler packages have rarely been tested at a reduced application rate. Eight site-years of data were collected at four Utah farms from 2018 to 2020, to evaluate crop yield and quality responses to full and reduced rates of each system in alfalfa, corn, and small grains. Soil water tension was also measured. Data showed that the advanced systems were sometimes able to maintain yield and quality while applying 15 to 25% less water, yet there were situations where MESA outperformed the advanced systems. This led us to conclude that there is not one style that will have the best results all the time, but that tailoring the package to the field characteristics is where the optimization with these packages can occur. Therefore, this chapter is being published as an Extension Guidebook for farmers.
Towards a unitary, renormalizable and ultraviolet-complete quantum theory of gravity

description: For any fundamental quantum field theory, unitarity, renormalizability, and relativistic invariance are considered to be essential properties. Unitarity is inevitably connected to the probabilistic interpretation of the quantum theory, while renormalizability guarantees its completeness. Relativistic invariance, in turn, is a symmetry which derives from the structure of spacetime. So far, the perturbative attempt to formulate a fundamental local quantum field theory of gravity based on the metric field seems to be in conflict with at least one of these properties. In quantum Hořava gravity, a quantum Lifshitz field theory of gravity characterized by an anisotropic scaling between space and time, unitarity and renormalizability can be retained while Lorentz invariance is sacrificed at high energies and must emerge only as approximate symmetry at low energies. I review various approaches to perturbative quantum gravity with a particular focus on recent progress in the quantization of Hořava gravity, supporting its theoretical status as a unitary, renormalizable and ultraviolet-complete quantum theory of gravity.

description: The paper describes the basic characteristics of the traditional and strategic project management as well as analyses the differences between these two management disciplines. Given that traditional project management has, as an operational discipline, achieved rather impressive results in practice, new ideas were oriented towards connecting the strategic view of strategic management and the operational approach provided by project management. This in turn resulted in strategic project management, a new approach in the development of project management that suggests that projects should be managed in accordance with the strategic organizational goals and that the project execution should contribute to achieving both the project goals and the strategic organizational goals.
title: The synthesis and decomposition reactions of N-hydroxymethyltriazenes
Creators: name: Cheng, Shee Chau
Publisher: name: The Open University
Year: 1984

description: Two methods of synthesising l-aryl-3-hydroxymethyl-3- methyltriazenes have been examined. The method of Vernin's et.al. was found to be erroneous yielding bistriazenes instead. A mechanism for the formation of hydroxymethyltriazenes and bistriazenes has been proposed. Furthermore, modification of Steven's procedure enabled the synthesis of 4-chlorophenyl- hydroxymethyltriazene. Hydroxymethyltriazenes were shown to decompose in the presence of metal ion in non-agueous solutions to give the corresponding arylamines. This reaction was shown to follow a consecutive pseudo-first-order mechanism with the intermediacy of monomethyltriazene. Moreover, the reaction was found to be metal ion and not proton catalysed. Compared to hydroxymethyltriazenes, monomethyltriazenes are more reactive towards metal ions. This is believed to be due to the higher nucleophilicity of the triazene group in monomethyltriazenes. A salient feature of this study was the stabilising effect of a heteroaryl ring in the decomposition of hydroxymethyltriazenes. The ability of the heteroaryl ring to interact with metal ion is thought to be responsible for this stabilising effect. This was confirmed by the lanthanide shift reagent study. Lanthanide induced chemical shifts are reported for hydroxymethyltriazenes and related compounds. The induced shifts for both Eu(fod)3 and Pr(thd)3 reveal that the hydroxymethyltriazenes bind to the Mn+ ion via the hydroxymethyl oxygen atom and that the binding ability of this atom is lowered when the hydroxyl proton is replaced with a bulky group. The presence of bases was also found to promote the decomposition of hydroxymethyltriazenes. In this instance, however, monomethyltriazenes are stable enough to exist as the product. The base requires an X-H bond for catalytic activity.

description: We calculate the contribution to the ultraviolet background (UVB) from thermal emission from gas shock heated by cosmic structure formation. Our main calculation is based on an updated version of Press-Schechter theory. It is consistent with a more empirical estimate based on the observed properties of galaxies and the observed cosmic star formation history. Thermal UVB emission is characterized by a hard spectrum extending well beyond 4 Ry. The bulk of the radiation is produced by objects in the mass range 10^11-13 M_solar, i.e. large galaxies and small groups. We compute a composite UVB spectrum due to QSO, stellar and thermal components. The ratio of the UVB intensities at the H and He Lyman limits increases from 60 at z=2 to more than 300 at z=6. A comparison of the resulting photoionization rates to the observed Gunn-Peterson effect at high redshifts constrains the escape fraction of ionizing photons from galaxies to be less than a few percent. Near 1 Ry, thermal and stellar emission are comparable amounting to about 10 %, 20 % and 35 % of the total flux at redshifts of 3, 4.5 and higher, respectively. However, near the ionization threshold for HeII, the thermal contribution is much stronger. It is comparable to the QSO intensity already at redshift ~3 and dominates at redshifts above 4. Thermal photons alone are enough to produce and sustain HeII reionization already at z~6. We discuss the possible implications of our results for the thermal history of the intergalactic medium, in particular for HeII reionization.

Investigations of Substrate Reduction by Nitrogenase: Light Powered Substrate Reduction by a CdS:FeMoco System and Understanding Dinitrogen Inhibition of Electron Transfer
Creators: name: Kallas, Hayden
Publisher: name: Utah State University
Year: 2021

description: Nitrogen fixation is a key step of the nitrogen cycle which makes biologically inert N2 gas available for organisms to use in the form of ammonia. Nitrogen fixing microorganisms all contain the same enzyme called nitrogenase which catalyzes the six electron transfers to N2 required for conversion into ammonia. Nitrogenase is a two-component enzyme that contains a cofactor composed of iron and sulfur as well as heavier metals whose identity can be molybdenum, vanadium, or an additional iron atom depending on the variant. The two components of nitrogenase are the MFe protein and the Fe protein. The Fe protein delivers electrons to the MFe protein where N2 conversion to ammonia takes place. Two outstanding topics of interest in the nitrogenase research field are (1) how the iron-sulfur active site cofactor of nitrogenase (FeMoco) interacts with the protein to facilitate electron transfer to substrates, (2) why electron transfer rates are sometimes slowed by N2 despite a long-held understanding that the rate of electron transfer is substrate invariant.
The first question was addressed by using CdS nanoparticles to deliver electrons to the extracted active site cofactor of nitrogenase. This system allows the kinetics of substrate reduction at the cofactor to be investigated in order to understand what role the protein environment plays in reactivity. The CdS:cofactor system was characterized and its feasibility as an investigative tool was examined. The CdS:cofactor reductive system was found to be susceptible to decomposition resulting in the formation of multiple catalytic species; eliminating the current system as a mechanistic investigation tool.
The second question was addressed by investigating what conditions and methods of measurement determine if N2 inhibition of electron transfer is observed. Several conditions were found to determine the extent of N2 inhibition observed including pH, nitrogenase subunit ratio, and the method by which electron transfer is measured. The results of these experiments led to the proposal of a novel, unaccounted-for product of nitrogenase catalysis under N2 as an explanation for N2 inhibition.

We use data from Type Ia Supernovae (SNe Ia), Baryon Acoustic Oscillations (BAO) and Cosmic Chronometers (CC) to test MOG predictions. For this, we perform $χ^2$ tests considering fixed values of $H_0$ and $V_G$, the self-interaction potential of one of the scalar fields in the theory. Our results show that the MOG theory is in agreement with all data sets for some particular values of $H_0$ and $V_G$, being the BAO data set the most powerful tool to test MOG predictions, due to its constraining power.

description: Marketing is a science that deals with the market, market needs and the ways of meeting these needs. Marketing, as a business philosophy of intensive production, is focused on analyzing and noticing all the problems referring to the distribution and selling of the goods from the producer to the consumer. This field is constantly developing together with market expansion and its goal is to set the theoretical background for the market business strategies. In marketing theory, the market success is most commonly related to the understanding and meeting of market needs, but, new, more advanced trends are emerging. Etymologically, marketing is a business concept directed at buyers. In this concept, the projection of products and services starts with consumers’ needs, and the aim of the activity is customer satisfaction. In companies where the marketing concept is entirely in use, the consumers are not only the marketing department’s concern, but all the employees’ concern who do their work aware of the fact that they do it for the sake of the consumer.
Invasive Plant Occurrence Across Agency Boundaries: Two Case Studies from California
Creators: name: Otto, Natalie
Publisher: name: Utah State University
Year: 2021

description: Non-native invasive species (NNIS) are a major concern confronting land managers in and surrounding protected areas such as national parks. These areas are managed by a variety of entities, all of which have different mandates, management priorities, and resources that are allocated to NNIS programs. These differences can result in ecological divergences at land boundaries and can create barriers to cooperative management. Through interviews and ecological data collection, this research addresses three topics; 1. It identifies disparities in NNIS and disturbance occurrence between jurisdictions and tests the strength of correlations between these variables; 2. It seeks to determine what role elevation plays in occurrence of NNIS, and; 3. It identifies the current challenges and extent of cooperative interactions among entities. Coordination and communication were the dominant forms of cooperative management, while true collaboration was scarce. Ecological data and analysis did not find significant differences in occurrence of weeds or disturbances across jurisdictions, nor did it find a significant difference in the correlation between weeds and disturbances when controlling for site. Based on these findings, I provide recommendations on how to address collaboration challenges, while considering the effects of management related disturbances on NNIS.

Evolution of Cosmological Perturbations in the Universe dominated by Multiple Scalar Fields
Creators: name: Hamazaki, Takashi
Publisher: name: arXiv
Year: 2003
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: By efforts of several authors, it is recently established that the dynamical behavior of the cosmological perturbation on superhorizon scales is well approximated in terms of that in the long wavelength limit, and the latter can be constructed from the evolution of corresponding exactly homogeneous universe. Using these facts, we investigate the evolution of the cosmological perturbation on superhorizon scales in the universe dominated by oscillating multiple scalar fields which are generally interacting with each other, and the ratio of whose masses is incommensurable. Since the scalar fields oscillate rapidly around the local minimum of the potential, we use the action angle variables. We found that this problem can be formulated as the canonical perturbation theory in which the perturbed part appearing as the result of the expansion of the universe and the interaction of the scalar fields is bounded by the negative power ot time. We show that by constructing the canonical transformations properly, the transformed hamiltonian becomes simple enough to be solved. As the result of the invetigation using the long wavelength limit and the canonical perturbation theory, under the sufficiently general conditions, we prove that for the adiabatic growing mode the Bardeen parameter stays constant and that for all the other modes the Bardeen parameter decays. From the viewpoint of the ergodic theory, it is discussed that as for the Bardeen parameter, the sigularities appear probabilistically. This analysis serves the understanding of the evolution of the cosmological perturbations on superhorizon scales during reheating.

title: The vibrating string in keyboard instruments
Creators: name: Lincoln, John
Publisher: name: The Open University
Year: 1983

description: In this thesis some aspects of the acoustics of the piano and harpsichord are discussed. Initially the wave equation for the vibrating string is derived. Since the strings in the piano are not perfectly flexible the wave equation is extended to take into account the stiffness of the strings. The Wave equation thus modified affects the frequencies of the partials of the strings. The predicted frequencies are compared with the actual frequencies on a piano. The discussion is then continued to show how this affects the actual tuning of the instrument. Computer and programmable calculator programmes are used in these predictions. The theoretical basis for the spectra of piano and harpsichord strings are discussed and brief notes included on the effects of hammer width and string stiffness. The final experimental section deals with the reverberation times for piano and harpsichord strings, taking account of the effects of multiple stringing. Multiple stringing is found to affect the piano strings but not the harpsichord strings reverberation times. No accurate measurements of harpsichord reverberation times could be found in the literature, and the experiments were extended to include the effects of the buff stop. The conclusions contain several suggestions for further study and stress the importance of piano scaling. It is noted that scaling is also of importance to the musician when selecting instruments for the performance of duets, especially with regard to tuning compatibility.

description: The privatization of SOEs has not brought the expected development incentive in the textile industry in Serbia. Sales of capital, as the dominant model of this process was most unfavorable form of ownership restructuring of companies in this industry, and labor intensive sectors around our economy. With the weight of accumulated financial problems and significant redundancies, most large and medium-sized enterprises, which were the backbone of our textile industry, passed by the wider interest of private investors. FDI inflow was only symbolic, without significant support of state institutions, seriously hampered the implementation of inelastic legal solutions. Instead of applying more convenient model of privatization, this process is, in these okolnostime, necessarily directed towards the liquidation of a large number of companies, with highly negative consequences for the structure and development potential of this branch of industry as a whole. Turning off the key enterprises in the raw materials sector, there was a vertical disintegration of her, with long-term negative effects on the further balanced development. Import dependence has become a key structural feature of the industry despite the dynamic growth of exports in the last ten years. Created the elastic structure of production capacities, with much slower process of their concentration on market principles.
Remote Ocean Forcing on Interannual-to-Decadal Climate Variability through Inter-Basin Interactions
Creators: name: Johnson, Zachary F.
Publisher: name: Utah State University
Year: 2021

description: This dissertation explores the connection between ocean basins through the atmosphere by employing observational data analyses and a climate modeling approach. Sea surface temperature changes in the tropical Pacific, known as the El Niño Southern Oscillation, can influence worldwide weather and sea surface temperatures in other ocean basins. For instance, tropical Pacific sea surface temperatures can impact the Atlantic and Indian Oceans through airflow changes along the equator. However, Atlantic and Indian Ocean sea surface temperature changes can also influence the tropical Pacific through similar processes. Therefore, it is challenging to identify the mechanisms of these remote connections between ocean basins due to two-way interconnections. To better understand how ocean basins are connected by the atmosphere, this dissertation uses climate models to simulate the climate response from ocean forcing. Results in this dissertation show that the three tropical oceans are more tightly connected than previously thought. After introducing the dissertation in Chapter 1, Chapter 2 shows how the Atlantic Ocean can cause long-lasting changes in Australia rainfall through teleconnections. Chapter 3 reveals that Atlantic sea surface temperatures can influence north Pacific sea surface temperatures through remote teleconnections. Lastly, Chapter 4 explores trends in rainfall in the Pacific and the Indian Ocean from the 1980s to the 2010s. The results in this dissertation provide a path for-ward to increase the forecasting capability of the El Niño Southern Oscillation and help the climate science community enhance our understanding of climate variability.

description: The Solar Probe Cup (SPC) is a Faraday Cup instrument onboard NASA's Parker Solar Probe (PSP) spacecraft designed to make rapid measurements of thermal coronal and solar wind plasma. The spacecraft is in a heliocentric orbit that takes it closer to the Sun than any previous spacecraft, allowing measurements to be made where the coronal and solar wind plasma is being heated and accelerated. The SPC instrument was designed to be pointed directly at the Sun at all times, allowing the solar wind (which is flowing primarily radially away from the Sun) to be measured throughout the orbit. The instrument is capable of measuring solar wind ions with an energy/charge between 100 V and 6000 V (protons with speeds from $139-1072~km~s^{-1})$. It also measures electrons with an energy between 100 V and 1500 V. SPC has been designed to have a wide dynamic range that is capable of measuring protons and alpha particles at the closest perihelion (9.86 solar radii from the center of the Sun) and out to 0.25 AU. Initial observations from the first orbit of PSP indicate that the instrument is functioning well.

description: The outcome of helium burning is the formation of the two elements, carbon and oxygen. The ratio of carbon to oxygen at the end of helium burning is crucial for understanding the final fate of a progenitor star and the nucleosynthesis of heavy elements in Type II supernova, with oxygen rich star predicted to collapse to a black hole, and a carbon rich star to a neutron star. Type Ia supernovae (SNeIa) are used as standard candles for measuring cosmological distances with the use of an empirical light curve-luminosity stretching factor. It is essential to understand helium burning that yields the carbon/oxygen white dwarf and thus the initial stage of SNeIa. Since the triple alpha-particle capture reaction, $^{8}Be(α,γ)^{12}C$, the first burning stage in helium burning, is well understood, one must extract the cross section of the $^{12}C(α,γ)^{16}O$ reaction at the Gamow window (300 keV) with high accuracy of approximately 10% or better. This goal has not been achieved despite repeated strong statements that appeared in the literature. In particular constraint from the beta-delayed alpha-particle emission of $^{16}N$ were shown to not sufficiently restrict the p-wave cross section factor; e.g. a low value of $S_{E1}(300)$ can not be ruled out. Measurements at low energies, are thus mandatory for determining the elusive cross section factor for the $^{12}C(α,γ)^{16}O$ reaction. We are constructing a Time Projection Chamber (TPC) for use with high intensity photon beams extracted from the HI$γ$S/TUNL facility at Duke University to study the $^{16}O(γ,α)^{12}C$ reaction, and thus the direct reaction at energies as low as 0.7 MeV.

Semiotic Narrative by Greimas

description: Σκοπός της παρούσας διπλωματικής είναι η σημειωτική αφηγηματολογική μελέτη του γαλλικού παραμυθιού Le Maître Chat ou Le Chat Botté του Charles Perrault (1697) με την εικονογράφηση του Gustave Doré (1862). Η ανάλυση βασίστηκε στη θεωρία αφηγηματολογίας του Algirdas Julien Greimas, Sémantique Structurale: Recherche de method (1966) και στην εφαρμογή της που προτείνουν οι Α.-Φ. Λαγόπουλος και K. Boklund-Λαγοπούλου στο Θεωρία Σημειωτικής: Η παράδοση του Ferdinand de Saussure (2016). Με την μεθοδολογία αυτήν επιχειρείται μια νέα προσέγγιση της αφηγηματικής δομής του γνωστού παραμυθιού και της εικονογράφησής του, ακολουθώντας την αντίθετη τροπή της γενετικής διαδρομής, αρχίζοντας δηλαδή από το επίπεδο της επιφάνειας του λόγου και διεισδύοντας στο βαθύ επίπεδο (λεκτικό και οπτικό), τόσο της αφηγηματικής σύνταξης οσο και της σημασιολογίας των δυο κειμένων (λεκτικό και οπτικό) με στόχο να αναδυθεί το κρυφό τους νόημα.
description: The purpose of this thesis is the semiotic narratological study of the French fairy tale Le Maître Chat ou Le Chat Botté by Charles Perrault (1697), as illustrated by Gustave Doré (1862). The analysis is based on the narrative theory of Algirdas Julien Greimas, Sémantique Structurale: Recherche de méthode (1966), and on its application proposed by A.-Ph. Lagopoulos and K. Boklund-Lagopoulou in Theory of Semiotics: The Tradition of Ferdinand de Saussure (2016). This methodology attempts a new approach to the narrative structure of the well-known fairy tale and its illustration, following the path of the genetic trajectory “in reverse”, starting from the surface level of discourse and penetrating to the deep level of the narrative syntax and semantics of the two texts (verbal and visual) with the aim of revealing their hidden meaning.

description: Human resources own the knowledge, inovative potential, intellectual and physical capacity. People are those who create these products and services, control the quality, sell products, manage and finance the production process, determine strategy and objectives of the company... Without this resource, all work would be impossible. Correct selection of new employees is very important for every company because the companies which are skilled to select and retain quality employees will be achived thanks to competitive advantage in the market. The most common method of employment of labor in Serbia is through friends or relatives, followed by ads of the National Employment Service and other methods. The rarest are the recruitment of workers through the employment of private employment agencies, the institutions for education/training, and improvement of existing employees in the company.
title: The voluntary reading habits of 10 - 12 year olds: a survey analysed with reference to scores on Cattell's children's personality questionnaire
Creators: name: Blackburn, Jennifer C
Publisher: name: The Open University
Year: 1985

description: The entire First Year (n = 85) of a small Catholic Comprehensive school was surveyed in order to investigate voluntary reading habits. These pupils had at 10+ answered the Primary Questionnaire, and subsequently at 12+ reported on one month's reading, using a specially developed measure. The study's main phase, however, assessed pupils aged 11+. Half the group recorded their reading on Book Forms while the other matched half were controls. A Secondary Questionnaire administered before and after the five-week experiment found no significant differences in numbers of books read. All the children filled in time-sampling Diaries on three occasions during the experimental period, and the advantages of this method of establishing how much voluntary reading is undertaken are discussed. A sub-group of particularly 'avid' readers was distinguished and compared to the others, with especial reference to whether books were finished or not and whether they had been read previously. Girls were found to be more avid than boys on various measures. Analysis of the reasons for choice recorded in the Book Forms, together with other evidence, suggested that one of the reasons why the children did not read more was that they lacked the skill to choose books they would enjoy from the thousands available, and that the selection strategies they did employ were likely to lead to disappointment. Finally, Cattell's Children's Personality Questionnaire was administered to all pupils. The avid readers tended to be more intelligent, more stable emotionally and less excitable than the others. If they were girls, they were also more vigorous and zestful than other girls; if boys, they were more self-controlled, with a stronger self-concept than other boys. These and other significant findings may indicate some of the personal qualities which sustained book- reading requires, and thus contribute towards an explanation of the variation in voluntary reading habits in these children.
Developing Advanced Electrodes and Electrolytes for Energy Storage Beyond Li Ion Batteries

description: Electric vehicles, smart phones, and portable computers are all powered by lithium-ion batteries. This is because Li-ion batteries can store more energy in less space than other battery technologies. Also, they are rechargeable and last for a long time. The most recent 2019 Nobel prize in chemistry was awarded to John Goodenough, M. Stanley Whittingham and Akira Yoshino “for the development of lithium-ion batteries”. Through their work, they have made possible cars that do not burn fossil fuels and phones that are wireless and portable. Not only can Li-ion power your phone, it is an incredibly efficient way to store energy from renewable sources such as wind, solar, or hydroelectric.
From the introduction of the Li-ion Battery into the public market until now the fundamentals of the battery technology have remained relatively the same. This means a metal oxide electrode containing Co is combined with a Li containing electrolyte. Both Co and Li are rare elements that have sustainability issues. Replacing these components could make batteries more energy dense and sustainable for future generations.
The first part of this work describes an improved synthetic method to make battery electrodes from renewable organic materials and earth abundant elements. These electrodes were found to provide energy densities rivaling those found in current Li-ion technologies. The electrodes featured in this work make use of a type of material called metal organic frameworks (abbreviated as MOFs). The MOFs in this work were found to work well for Li batteries and last for over 1000 cycles. Spectroscopic techniques were used to prove that it is advantageous for both the metal and the organic component of the MOFs to store energy.
The other unsustainable component of the battery is the Li electrolyte. In this work Ca electrolytes were improved and developed. Ca is a highly abundant and nontoxic element that is found everywhere. These qualities make it a highly suitable alternative to Li. Ca electrolytes have different properties than Li. Here the very important contributions of the solvent used in the electrolyte are examined. Not very many Ca electrolytes currently work for batteries. In this dissertation a new working Ca electrolyte was discovered and fully tested for its ability to work in Ca batteries. Two full functioning Ca batteries were tested with different electrolytes and electrodes. These batteries are the most energy dense Ca batteries ever reported and are directly competitive with Li-ion batteries.

description: In the quiet regions on the solar surface, turbulent convective motions of granulation play an important role in creating small-scale magnetic structures, as well as in energy injection into the upper atmosphere. The turbulent nature of granulation can be studied using spectral line profiles, especially line broadening, which contains information on the flow field smaller than the spatial resolution of an instrument. Moreover, the Doppler velocity gradient along a line-of-sight (LOS) causes line broadening as well. However, the quantitative relationship between velocity gradient and line broadening has not been understood well. In this study, we perform bisector analyses using the spectral profiles obtained using the Spectro-Polarimeter of the Hinode/Solar Optical Telescope to investigate the relationship of line broadening and bisector velocities with the granulation flows. The results indicate that line broadening has a positive correlation with the Doppler velocity gradients along the LOS. We found excessive line broadening in fading granules, that cannot be explained only by the LOS velocity gradient, although the velocity gradient is enhanced in the process of fading. If this excessive line broadening is attributed to small-scale turbulent motions, the averaged turbulent velocity is obtained as 0.9 km/s.
