description: A systematic investigation on vapor-liquid equilibria (VLE) of dipolar and quadrupolar fluids is carried out by molecular simulation to develop a new Helmholtz energy contribution for equations of state (EOS). Twelve two-center Lennard-Jones plus point dipole and point quadrupole model fluids (2CLJDQ) are studied for different reduced dipolar moments mu^{*2}=6,12, reduced quadrupolar moments Q^{*2}=2,4 and reduced elongations L^*=0, 0.505,1. Temperatures cover a wide range from about 55% to about 95% of the critical temperature of each fluid. The NpT + test particle method is used for the calculation of vapor pressure, saturated densities and saturated enthalpies.Critical data and the acentric factor are obtained from fits to the simulation data.On the basis of this data, an EOS contribution for the dipole-quadrupole cross-interactions of non-spherical molecules is developed. The expression is based on a third-order perturbation theory and the model constants are adjusted to the present 2CLJDQ simulation results. When applied to mixtures, the model is found to be in excellent agreement to results from simulation and experiment. The new EOS contribution is also compatible with segment-based EOS, like the various forms of the Statistical Associating Fluid Theory (SAFT) EOS.

description: The concept of an exciton as a quasiparticle that represents collective excited states was originally adapted from solid-state physics and has been successfully applied to molecular aggregates by relying on the well-established limits of the Wannier exciton and the Frenkel exciton. However, the study of excitons in more complex chemical systems and solid materials over the past two decades has made it clear that simple concepts based on Wannier or Frenkel excitons are not sufficient to describe detailed excitonic behavior, especially in nano-structured solid materials, multichromophoric macromolecules, and complex molecular aggregates. In addition, important effects such as vibronic coupling, the influence of charge-transfer (CT) components, spin-state interconversion, and electronic correlation, which had long been studied but not fully understood, have turned out to play a central role in many systems. This has motivated new experimental approaches and theoretical studies of increasing sophistication. This article provides an overview of works addressing these issues that were published for A Special Topic of the Journal of Chemical Physics on "Excitons: Energetics and spatio-temporal dynamics" and discusses their implications.

description: Abstract

The objective of this study was the isolation and characterization of pigmented bacteria, with a focus on exploring their pigment-producing capacities and assessing the practical applicability of these pigments in textile dyeing procedures. Four distinct pigmented bacterial strains—Chryseobacterium meningosepticum (Pf5), Proteus vulgaris (HC), Aeromonas hydrophila (Pf4), Halomonas sp. (AST)—were carefully isolated and subjected to an investigation into optimized culture and media variables. The identified optimal conditions for both growth and pigment production included the use of peptone broth media at 37°C, pH=7, 2-4% salination in the growth media, under shaking and dark conditions. The biopigments were subsequently extracted in organic solvents, including diethyl ether, chloroform, ethanol, and methanol. UV/Vis spectrophotometry revealed peak absorbance at 440-450nm for pigments extracted using diethyl ether and chloroform. The antibacterial activity assessment confirmed the presence of antibacterial substances within these biopigments. Furthermore, the extracted pigments underwent comprehensive testing for their coloring potential on diverse materials such as fabrics, soap, cotton, and tissue paper, demonstrating a non-degradable colorant. These findings highlight the potential applications of these bacteria in advancing sustainable and environmentally friendly dyeing processes within the textile industry.

description: A Lyapunov-based control design for natural trajectory-tracking problems is analyzed for quantum states where the analysis in the generic case is not applicable. Using dynamical systems tools we show almost global asymptotic stability for stationary target states subject to certain conditions on the Hamiltonians, and discuss effectiveness of the design when these conditions are not satisfied. For pseudo-pure target states the effectiveness of the design is studied further for both stationary and non-stationary states using alternative tools.

Rex prudens et sapiens.
Semantica della regalità negli specula principum d'epoca tardomedievale (secoli XII-XV)

Subjects: M-FIL/08 Storia della filosofia medievale

description: La ricerca di Roberta Frigeni, svolta ad ampio spettro diacronico, è condotta su di una campionatura
di specula principum - editi ed inediti - elaborati tra XII e XV secolo, e ne indaga il linguaggio
quale referente privilegiato, rilevandone persistenze terminologiche e nuclei sintagmatici ricorrenti,
al fine di individuare concetti utili a delineare un lessico politico proprio di questa testualità, in
corrispondenza al sorgere dell’entità statale europea nel XIII secolo (con particolare riguardo
all’area francese, ai regni di Luigi IX e Filippo il Bello). A partire da un’analisi critica delle tesi di
Quentin Skinner circa la ‘ridefinizione paradiastolica’ del sistema delle virtù classiche entro il
trattato De principatibus, lo studio innesca un percorso di indagine à rebours che - sondando il
linguaggio - rintraccia nella trattatistica delle institutiones regum del XV secolo (Pontano, Patrizi,
Carafa, Platina) e degli specula principum medievali (Elinando di Froidmont, Gilberto di Tournai,
Vincenzo di Beauvais, Guglielmo Peraldo, Egidio Romano, Guido Vernani) una consonanza di
motivi nella sintassi e nell’immaginario preposti ad illustrare le potenzialità semantiche del nome di
prudentia, individuata quale unica virtù sopravvissuta alla ‘ridescrizione’ del codice etico operata
da Machiavelli. Indagando i progressivi ampliamenti del campo semantico sorto attorno al nome
della virtù di prudenza entro la letteratura speculare, la ricerca mostra come il dialettico rapporto
con i lessemi di sapientia, astutia, fides ed experientia abbia avuto un ruolo determinante per il
sorgere di un’immagine del principe emancipata dalla figura biblica del “rex sapiens”, e per la
formazione di un lessico ospitale delle manifestazioni concrete del vivere politico ed economico. I
processi di dilatazione e rarefazione del bacino semantico di prudentia sono, infatti, funzionali ad
illustrare come il linguaggio della testualità speculare registri l’acquisizione di nuove
strumentazioni teoriche grazie al rinnovamento delle fonti a disposizione lungo il secolo XIII, che -
sostituendo progressivamente il più recente dossier aristotelico al solo apparato veterotestamentario
- permettono di integrare la concezione delle virtù in senso operativo, adattandola alle esigenze
politico-economiche dei nuovi contesti istituzionali monarchici.

Rituali di consumo alimentare tra flussi di globalizzazione e
pratiche di localizzazione

description: La tesi di dottorato “Buoni cibi per buoni pensieri. Rituali di consumo alimentare tra flussi di
globalizzazione e pratiche di localizzazione” verte attorno allo studio e all’approfondimento della
sociologia dei consumi, con particolare riferimento alle relazioni che si possono instaurare tra i
comportamenti alimentari collettivi a livello locale e il sistema globale.
Il focus dell’analisi si incentra sulla sostenibilità dei consumi, fenomenologia esemplificativa di
una modalità di rapporto degli uomini con i cibi innovativa e al contempo nient’affatto scontata: non
soltanto a livello individual-collettivo come strumento di intelligibilità sociale e costruzione di senso,
ma anche sul piano sistemico come rapporto con l’ambiente e il mondo circostante. In effetti, il
percorso di studi che ha condotto all’elaborazione teorica ed empirica della tesi di dottorato, pur
muovendo da studi radicati nella letteratura socio-antropologica come il consumo dei cibi e la cultura
da essi veicolata, viene oggi inquadrata all’interno di nuovi scenari sullo sfondo del mutamento socioeconomico:
le pratiche di sostenibilità causate dalle ambivalenti ripercussioni giocate dalla
globalizzazione sui sistemi sociali. Se è vero infatti che oggi si vive in una società complessa,
caratterizzata dalla crescente centralità del sistema del consumo rispetto agli altri sottosistemi, è
evidente come una ri-lettura critica delle sue dimensioni simboliche ed intersoggettive nel senso del
ridimensionamento degli aspetti legati alla mercificazione e al materialismo, faccia sì che la tesi
dottorale si orienti sulla ricerca di una sostenibilità oggi tanto diffusa, da sostanziarsi sempre più anche
nelle pratiche di consumo alimentare.
Oggetto specifico di questo lavoro sono dunque, senza pretesa di esaustività ma rappresentative
del contesto spaziale preso in esame, fenomenologie del consumo alimentare italiano all’interno di uno
scenario globale: in particolare, si affronta la nuova cultura della sostenibilità che nasce dall’incontro
fra i cittadini-consumatori e le complesse tematiche emergenti del sistema sociale di riferimento.

description: Abstract: Objective: The present review describes how children experience hereditary cancer risk communication within the family. Methods: Searches for studies between 1990 and 2020 on PubMed and EBSCO were undertaken, and fifteen studies met the inclusion criteria, following PRISMA guidelines. The findings informed: (1) how, when and what is discussed about hereditary cancer risk in the family; (2) how does family communication about hereditary cancer risk impact children on psychosocial and behavioral outcomes; (3) what are the child’s preferences regarding hereditary cancer risk communication within the family. Results: Disclosure is done mostly by both parents, or mothers only, which is in accordance with the children's preferences. Children value open communication about cancer risk with their parents, although they report experiences of fear, surprise, feeling unhappy, and concern about the increased risk of cancer. Regardless of the method of disclosure, children may be particularly sensitive to their parent’s emotional state at the time of disclosure, and they learn from their parents’ experiences the potential implications of cancer risk. Children also report that it would be helpful to learn more about genetic cancer syndromes via written materials, and/or meet a genetic counselor. Conclusions: Children rely on their parents as the primary models of the hereditary cancer experience. Therefore, parents play a central role in the psychological adjustment of children. Findings point to the relevance of family-centered care in hereditary cancer risk that targets not only the mutation carrier individually but also their children and partners.

description: The gyrokinetic particle simulation serves as a powerful tool for the studies of transport, nonlinear phenomenon, and energetic particle physics in tokamak plasmas. While most gyrokinetic simulations make use of the scalar and vector potentials, a new model (GK-E&B) has been developed by using the E and B field in a general and comprehensive form and has been implemented in simulating kinetic Alfvén waves in uniform plasma [Chen et al, Science China Phys. Mechanics & Astronomy 64 (2021)]. In our work, the Chen et al. GK-E&B model has been expressed in general tokamak geometry explicitly using specific coordinates. Its reduction to the uniform plasma is verified and the numerical results show good agreement with the work by Chen et al. The theoretical dispersion relation and numerical results in the local screw pinch model are in excellent agreement. Numerical results show excellent performance in a realistic parameter regime of burning plasmas in terms of high values of $β/( M_e k_\perp^2 ρ_i^2)$, which is challenging for traditional methods due to the ``cancellation' problem. As one application, the GK-E&B model is implemented with kinetic electrons in the local limit. With the matched ITPA-TAE parameters, numerical results show the capability of the GK-E&B in treating the parallel electron Landau damping for realistic tokamak plasma parameters. As another application, the global GK-E&B model is implemented with the dominant electron contribution to $E_\|$ in the cold electron limit. Its capability in simulating the finite $E_\|$ due to the finite electron mass is demonstrated.

Subjects: Digital Readiness, Writing Performance, Philippines.

description: Abstract

This study was conducted to determine the relationship between digital readiness and the writing performance of university students. Four hundred students were selected through stratified random sampling. A Goolge Form survey questionnaire was used to obtain data from the students. The mean, Pearson r, and regression were used to interpret the received data. Results showed that digital readiness was highly correlated with students' writing performance. The data also revealed that digital readiness was significantly linked to students' writing motivation. The result of the exogenous variable had a considerable influence as a predictor of writing performance.
title: Resource Competition Among the Uinta Basin Fremont
Creators: name: Hora-Cook, Elizabeth A.
Publisher: name: Utah State University

description: Archaeologists describe the Uinta Fremont (A.D. 0 – 1300) as a mixed foraging-farming society that underwent a dramatic social change from A.D. 700 – 1000. Researchers observe through different architectural styles and subsistence activity a change from large, aggregated settlements to more dispersed and defensively oriented villages and hamlets. The Ideal Free Distribution (IFD) model provides an explanatory framework through which to interpret these changes. IFD predicts the order in which people or animals will occupy habitats based on a habitat’s relative suitability and suggests hypothetical behaviors that people or animals might engage in to improve or maintain the relative suitability of a habitat. One prediction of IFD is that behaviors indicating resource competition will become more frequent when population density increases. I test whether this hypothesis explains changes in storage features by considering storage behavior as a manifestation of resource competition, and I investigate whether storage feature frequency correlates with periods of Fremont population increases and paleoenvironmental degradation.
These tests explain aspects of Fremont culture change and suggest future research possibilities. Storage feature frequency, representing resource competition, remains low from A.D. 0 – 700, suggesting that the habitats could absorb growing Fremont populations. After A.D. 700, however, resource competition rose and remained high, a condition that likely spurred the defensive architecture and dispersed settlements that became increasingly common after A.D. 1000. The successes and limitations of applying IFD to the archaeological record point the way toward future uses of the model to investigate settlement spacing and reaffirm the use of radiocarbon data in archaeological science.
title: Route-Finding: Developing Curricular Knowledge and Impacting Practice Through a Collaborative Curriculum Mapping Process
Creators: name: Reina, Laura J.
Publisher: name: Utah State University
Year: 2018

description: Research indicates curriculum mapping is beneficial for teachers and students. However, it is not effectively implemented because there are barriers in time, support, and knowledge. This research sought to remove those barriers and study the impact on teachers’ practice when they were able to work together to develop a curriculum map. The focus of the teachers’ map was the Kindergarten through third grade English Language Arts curriculum.
This work included a series of professional development sessions where teachers worked collaboratively to gain a greater understanding of the curriculum and develop a sequence from kindergarten through third grade. Teachers’ worked collaboratively to gain a deep understanding of what they were supposed to teach and how that would manifest in practice.
As teachers constructed their own understanding of the curriculum they made decisions about the expectations for students at each grade level and were able to discuss practices as a group. These discussions led teachers to be more intentional in their planning and instruction. They felt as though they had developed some consistency while still maintaining their freedom to teach within their classroom however they wanted.
I observed teachers in their classrooms and then met with them individually to talk about the impact of our work on their practice. Several ideas emerged. First, they saw a need for understanding of the content, and the value of gaining that knowledge as a group. They believed that their teaching would be more intentional as a result of our work and that this intentionality would make them higher quality reading teachers. They believed that increased intentionality, along with consistency from grade to grade and shared expectations had the potential to improve student achievement. Furthermore, teachers gained greater confidence from this work which could also improve their impact as teachers.
The community of practice was essential in moving teachers through this work as it provided them a trusting group with mutual goals and a willingness to support and challenge one another.It was essential that teachers first be able to work within a community of practice before they could traverse the journey of developing a curriculum map.

description: Abstract

Land use and land cover (LULC) analysis is a fundamental component of environmental monitoring and land management, offering valuable insights for urban planning and sustainable development. With the advancements in machine learning, new avenues have opened for gaining insights about urbanization trends, deforestation and climate change. There has been works done on LULC but they have used aerial images directly without applying image segmentation resulting in limited insights, inaccuracies, lack of localization and inability to distinguish between complex land cover types. To solve the drawbacks, we have applied image segmentation techniques to aerial images of LULC in this study. Five types of image segmentation techniques are used: 1) Threshold based, 2) Edge-based, 3) K-means clustering based, 4) Otsu’s segmentation, 5) Unet with ResUnet. The aerial images are divided into ten types of land uses. Dataset was prepared by acquiring aerial images of LULC, the images were pre-processed to enhance its quality and suitability for segmentation, and finally then one by one each segmentation technique was applied to all the images. Through experimentation and validation the most suitable image segmentation technique for LULC has been determined. The Accuracy, Jaccard Similarity Coefficient (JSC), Dice Similarity Coefficient (DSC), Intersection Over Union (IoU), Mean Intersection Over Union (MIOU) have been used to assess the effectiveness on LULC segmentation.
Direct observation of the radial magnetic field gradient in HD58260 from spectropolarimetry of NLTE lines in emission

description: Because of the unquestionable presence of magnetic fields in stars, their role in the structure of stellar atmospheres has for a long time been a subject of speculation. In our contribution to this discussion we present spectropolarimetric evidence of the decrease of the radial component of the magnetic field with altitude in the atmosphere of HD58260, a B-type magnetic star on the main sequence. We show that the Stokes V profiles of metal lines in emission of the outer atmosphere are evidence for a field three times weaker than from absorption lines from inner layers. The extra flow of energetic particles due to the magnetic-gradient pumping mechanism could be at the origin of the magnetospheres surrounding this class of stars and at the basis of the high energy phenomena observed. We also list a series of spectral lines useful for measuring the surface field of early-type stars.

description: World Wide Web is a huge data repository and is growing with the explosive rate of about 1 million pages a day. As the information available on World Wide Web is growing the usage of the web sites is also growing. Web log records each access of the web page and number of entries in the web logs is increasing rapidly. These web logs, when mined properly can provide useful information for decision-making. The designer of the web site, analyst and management executives are interested in extracting this hidden information from web logs for decision making. Web access pattern, which is the frequently used sequence of accesses, is one of the important information that can be mined from the web logs. This information can be used to gather business intelligence to improve sales and advertisement, personalization for a user, to analyze system performance and to improve the web site organization. There exist many techniques to mine access patterns from the web logs. This paper describes the powerful algorithm that mines the web logs efficiently. Proposed algorithm firstly converts the web access data available in a special doubly linked tree. Each access is called an event. This tree keeps the critical mining related information in very compressed form based on the frequent event count. Proposed recursive algorithm uses this tree to efficiently find all access patterns that satisfy user specified criteria. To prove that our algorithm is efficient from the other GSP (Generalized Sequential Pattern) algorithms we have done experimental studies on sample data.

title: Supporting Adolescent Metacognition in Engineering Design Through Scripted Prompts from Peer Tutors:  A Comparative Case Study
Creators: name: Strong, Kristin Marie
Publisher: name: Utah State University
Year: 2018

description: In 2013, developers of the Next Generation Science Standards implemented national K -12 directives and elevated engineering design to the level of scientific inquiry. Teaching design, however, is challenging to educators due to the complex nature of design problems, which cannot be solved via simple algorithms. Solving design problems requires a more reflective and iterative approach that emphasizes metacognitive skills like planning, monitoring, and taking another person’s perspective. Educators are further challenged by children’s immature metacognitive skills, which may be insufficient to engage in the entire design process.
A qualitative study of paired seventh graders demonstrated a pragmatic learning activity for enhancing adolescent designs during their earliest phases through guided peer interactions with metacognitive prompts. Four distinct interaction styles were observed among the pairs. Each style varied by which verbal and social phenomena were used to make changes. The metacognitive prompts used in the learning activity can be adapted to any design challenge.
Furthermore, an additional, exploratory case demonstrated a restructuring of the learning activity in which the metacognitive prompts were generated naturally by the students themselves. The student-generated prompts were design-specific and timely; delivered in the moment when a student was struggling with a design element. The result was a dynamic co-construction and co-ownership of the designs.
title: Comparison of Methods for Extracting Lactobacillus wasatchensis DNA from Broth Media, Milk, and Cheese for Subsequent PCR-Based Analyses
Creators: name: Allen, Tyler
Publisher: name: Utah State University
Year: 2018

description: The Western Dairy Center at Utah State University funded this project as part of its BUILD Dairy program with support from the dairy farmers of Idaho, to investigate the problem of splits that form in cheese during storage. The bacteria, Lactobacillus wasatchensis had previously been identified as a cause of unwanted gas production in cheese and the defects then make the cheese unsuitable for cutting into slices.
The project team proposed a two-year, $150,912 project to investigate methods for determining the presence of this bacterium in cheese by extracting DNA from the cheese and looking for DNA that was specific to Lactobacillus wasatchensis. The project identified a suitable method for extracting DNA and demonstrated that methods that extract DNA directly from the cheese are not as repeatable or reliable as a method that first separates and collects the bacteria from the cheese and then extracts the DNA.
While the detection limit for identifying Lactobacillus wasatchensis in cheese of 100,000 cells per gram, was not any lower than that which can be achieved using plating methods, this work provides the benefit of laying groundwork for selection of a NDA extraction method for use with cheese. Further research can now be applied to lower this detection limit so this bacterium can be identified in cheese earlier and thus reduce the problem of slits and cracks and provide a higher value of the cheese to the manufacturer.

description: Continuum Schwinger function methods for the strong-interaction bound-state problem are used to arrive at a unified set of parameter-free predictions for the semileptonic $K\to π$, $D\to π, K$ and $D_s \to K$, $B_{(s)} \to π(K)$ transition form factors and the associated branching fractions. The form factors are a leading source of uncertainty in all such calculations: our results agree quantitatively with available data and provide benchmarks for the hitherto unmeasured $D_s\to K^0$, $\bar B_s \to K^+$ form factors. The analysis delivers a value of $|V_{cs}| = 0.974(10)$ and also predictions for all branching fraction ratios in the pseudoscalar meson sector that can be used to test lepton flavour universality. Quantitative comparisons are provided between extant theory and the recent measurement of ${\cal B}_{B_s^0\to K^- μ^+ ν_μ}$. Here, further, refined measurements would be useful in moving toward a more accurate value of $|V_{ub}|$.

description: This paper presents a framework aimed at monitoring the behavior of aircraft in a given airspace. Nominal trajectories are determined and learned using data driven methods. Standard procedures are used by air traffic controllers (ATC) to guide aircraft, ensure the safety of the airspace, and to maximize the runway occupancy. Even though standard procedures are used by ATC, the control of the aircraft remains with the pilots, leading to a large variability in the flight patterns observed. Two methods to identify typical operations and their variability from recorded radar tracks are presented. This knowledge base is then used to monitor the conformance of current operations against operations previously identified as standard. A tool called AirTrajectoryMiner is presented, aiming at monitoring the instantaneous health of the airspace, in real time. The airspace is "healthy" when all aircraft are flying according to the nominal procedures. A measure of complexity is introduced, measuring the conformance of current flight to nominal flight patterns. When an aircraft does not conform, the complexity increases as more attention from ATC is required to ensure a safe separation between aircraft.

The COVID-19 pandemic has laid bare the existing vulnerabilities facing the most marginalized and disadvantaged groups. COVID-19 may not discriminate, but its impact has been far from even. Even within wealthier countries, ethnic, religious and racial minorities have poorer outcomes than the rest of society. Discrimination and bias in the health care system has contributed to the pandemic’s dramatic impact on Black, Latino and Native American populations. In an outbreak, such as that of COVID-19, people are labeled, stereotyped, discriminated against, treated separately, or experience loss of status because of a perceived link with a disease. Such treatment can negatively affect those with the disease, as well as their caregivers, family, friends and communities. The study assessed the health implications of racial discrimination of African migrants from Nigeria to Libya, Oman, Germany, Italy and Dubai during the COVID-19 pandemic and adopted forum focus group discussion. The population of study were migrant returnees in Benin City from which the sample size of 30 participants were drawn. The instrument of data collection was the focus group discussion guide which consisted of experiences of returnees, health challenges, psychological state, ability to access health care services and stigmatization during the pandemic lock down. Transcripts of focus groups were coded using emergent coding for code book development to classify the responses into meaningful units. The findings from this study showed that many of the migrants had negative and unpleasant experiences were psychologically unstable, the stigmatization affected them health wise and had no adequate access to health care services during the COVID-19 pandemic based on racism. Recommendations include asserting our different values, equality, non-discrimination, and mutual respect value, which are related to the affirmation of human rights.

description: We consider a dusty plasma, in which the dust particles have a magnetic dipole moment. A Hall-MHD type of model, generalized to account for the intrinsic magnetization, is derived. The model is shown to be energy conserving, and the energy density and flux is derived. The general dispersion relation is then derived, and we show that kinetic Alfvén waves exhibit an instability for a low temperature and high density plasma. We discuss the implication of our results.

title: Patterns of Use Before and After a Labeling Intervention Among Collegiate Division I Athletes at a Fueling Station
Creators: name: Buzzard, Julie A.
Publisher: name: Utah State University
Year: 2018

description: The Fueling Station at Utah State University was created to provide pre-workout fueling and post-workout recovery foods to the Utah State University athletes. The athletes use an online survey to mark what foods they selected after each visit to the Fueling Station.
There is a large amount of research on the lack of sports nutrition knowledge in collegiate athletes, but there is little information on the dietary intake of athletes, the education of athletes, and the education of macronutrient timing in athletes.
A food labeling system named “Gain Your Edge” food labels that targeted the education of timing was created in the Utah State University Fueling Station. It lets athletes know which food choices might be the most appropriate choices for certain periods of timing (i.e. pre-workout versus post-workout). The Fueling Station was selected as an outlet for education because it reaches a large percentage of all Utah State athletes each week.
The survey responses by the athletes were used to determine if the fueling station visits were appropriate or not appropriate based on the reported timing of eating, purpose of eating, and food selections. After four weeks of implementation, it was determined that the food labels did result in significant changes in percentage of appropriate fueling station visits for the athletes. However, almost all the athletes noticed the food labels, and more than 75% of the athletes said that the food labels influenced their food selection. This research project contributes important information about the patterns of use in a University-sponsored fueling station to the limited knowledge base of collegiate sports nutrition research.

title: Genetic Relationships Between Two Rare Plant Species, Aliciella caespitosa and A. tenuis, and Their Putative Progenitor, A. subnuda
Creators: name: McCracken, Carrie L.
Publisher: name: Utah State University
Year: 2001

description: Isolated populations have potential to become new species that should have less genetic variation than their ancestors. Small populations are more likely to lose genetic variation, which is, thus, expected to be greater in ancestors. Aliciella caespitosa and A. tenuis, two endemic species, may be derived from small populations of A. subnuda, a widespread species. Chloroplast DNA sequences were used to test this hypothesis. Allozyme data were used to compare genetic variation and numbers of alleles. Chloroplast data do not support the proposed relationships between A. subnuda and the other two species. Allozyme data were not more variable in A. subnuda. The data suggest that A. tenuis is derived from A. caespitosa, although the former did not show lower allozyme diversity. I detected fewer alleles in A. tenuis. These data suggest that the original population of A. tenuis was not small enough to lose genetic variation relative to its progenitor.

title: The Initiation of Infection by DNA From Bacteriophage Lambda
Creators: name: Elseth, Gerald D.
Publisher: name: Utah State University
Year: 1966

description: Deoxyribonucleic acid isolated from bacteriophage lambda can infect Escherichia coli K12 in the presence of adsorbed helper phage (Kaiser and Hogness, 1960; Kaiser, 1962). The manner in which lambda DNA enters the cell and the possible role of helper phage in the penetration process is still not clear. Kinetic studies conducted in this laboratory during the initial stages of infection by lambda DNA demonstrate a requirement for helper function during the penetration of an infectious molecule. Further investigation into this problem is needed and was the major objective of this study.

description: We describe the observations of the low-metallicity nearby galaxy AGC198691 (Leoncino dwarf) obtained with the Integral Field Unit of the instrument MEGARA at the Gran Telescopio Canarias. The observations cover the wavelength ranges 4304 - 5198 A and 6098 - 7306 A with a resolving power R ~ 6000. We present 2D maps of the ionized gas, deriving the extension of the HII region and gas kinematics from the observed emission lines. We have not found any evidence of recent gas infall or loss of metals by means of outflows. This result is supported by the closed-box model predictions, consistent with the oxygen abundance found by other authors in this galaxy and points towards Leoncino being a genuine XMD galaxy. We present for the first time spatially resolved spectroscopy allowing the detailed study of a star forming region. We use PopStar+Cloudy models to simulate the emission-line spectrum. We find that the central emission line spectrum can be explained by a single young ionizing cluster with an age ~ 3.5 +/- 0.5Myr and a stellar mass of about 2000 solar masses. However, the radial profiles of [OIII]5007 A and the Balmer lines in emission demand photoionization by clusters of different ages between 3.5 and 6.5Myr that might respond either to the evolution of a single cluster evolving along the cooling time of the nebula (about 3Myr at the metallicity of Leoncino, Z ~ 0.0004) or to mass segregation of the cluster, being both scenarios consistent with the observed equivalent widths of the Balmer lines

Extension of the spin-1/2 frustrated square lattice model: the case of layered vanadium phosphates

description: We study the influence of the spin lattice distortion on the properties of frustrated magnetic systems and consider the applicability of the spin-1/2 frustrated square lattice model to materials lacking tetragonal symmetry. We focus on the case of layered vanadium phosphates AA'VO(PO4)2 (AA' = Pb2, SrZn, BaZn, and BaCd). To provide a proper microscopic description of these compounds, we use extensive band structure calculations for real materials and model structures and supplement this analysis with simulations of thermodynamic properties, thus facilitating a direct comparison with the experimental data. Due to the reduced symmetry, the realistic spin model of layered vanadium phosphates AA'VO(PO4)2 includes four inequivalent exchange couplings: J1 and J1' between nearest-neighbors and J2 and J2' between next-nearest-neighbors. The estimates of individual exchange couplings suggest different regimes, from J1'/J1 and J2'/J2 close to 1 in BaCdVO(PO4)2, a nearly regular frustrated square lattice, to J1'/J1 ~ 0.7 and J2'/J2 ~ 0.4 in SrZnVO(PO4)2, a frustrated square lattice with sizable distortion. The underlying structural differences are analyzed, and the key factors causing the distortion of the spin lattice in layered vanadium compounds are discussed. We propose possible routes for finding new frustrated square lattice materials among complex vanadium oxides. Full diagonalization simulations of thermodynamic properties indicate the similarity of the extended model to the regular one with averaged couplings. In case of moderate frustration and moderate distortion, valid for all the AA'VO(PO4)2 compounds reported so far, the distorted spin lattice can be considered as a regular square lattice with the couplings (J1+J1')/2 between nearest-neighbors and (J2+J2')/2 between next-nearest-neighbors.
