description: Carnation (Dianthus caryophyllus L.) and chrysanthemum [Dendranthema grandiflorum (Ramat.) Kitam.] cut flowers are among the most important commodities that dominate flower markets throughout the world. Two major problems in the transportation and marketing of these flowers are their relatively short vase life and the rapid decline of their aesthetic value. In this respect, the current study investigates the effects of silver nanoparticles (AgNPs) on ethylene-sensitive (carnation) and ethylene-insensitive (chrysanthemum) cut flowers. Specifically, this research examines their morpho-physicochemical characteristics, antioxidant enzyme activities and vase life. Here, the AgNPs were synthesized by chemical methods and then applied on both flowers by a pulsing method. The treatments involved two concentrations of AgNPs (0.04 and 0.08gL-1) along with the control (deionized water), and the duration of exposure lasted for 24 h. Then, the flower stems were placed in an aqueous sucrose solution (4%) until the end of the experiment. All traits, except the vase life, were evaluated after 0, 3, 6 and 9 d following the treatments during the vase period. During this time, the control groups of both flowers showed considerable amounts of decrease in the relative fresh weight (RFW), vase solution uptake (VSU), flower diameter, membrane stability index (MSI) and total soluble carbohydrate (TSC). Meanwhile, there were increases in hydrogen peroxide content (H2O2) and peroxidase (POD) activity. The bacterial population of the stem end and total soluble protein (TSP) increased in carnation petals, but decreased in chrysanthemum petals. The activity of superoxide dismutase (SOD) dropped in carnation petals, whereas it rose in chrysanthemum petals. Using AgNPs at concentrations of 0.08 and 0.04gL-1 can optimally extend the vase life of carnation and chrysanthemum, respectively.

Attitudes

description: This research aims to contribute providing new evidence on individual attitudes toward equality, studying individual attitudes on equality of opportunities and equality of outcome in several European countries, and focusing both on how different factors affect differences between European countries as well as on differences within countries at the regional level. We use the European Social Survey’s years 2008 and 2016 along with other data sources to within-country differences, by focusing on regional-, individual-, and economic factors. The main results show, that both country- and regional-level variance in the equality attitudes were equally significant. Over time, we found that attitudes toward both equality of outcomes and opportunities attitudes have become stronger, yet opinions have become more fragmented. Countries that share similar systems, seem to be also similar in equality attitudes. On specific factors, we found that economic variables with political alignment were important in people’s attitudes on equality, while on a regional level higher economic output decreases agreement with equality of outcome.

description: Demand for fig fruit is increasing because of its high antioxidant capacity and health benefit for human. So, interest in maintaining bioactive components of fruit has been increased. However, antioxidant capacity of fruits decreases during storage. Fresh fruits of the well-known fig (Ficus carica L.) cultivar ‘Siyah’ were grown in Fars Province, Iran, treated with different concentrations of Aloe vera gel prior to being placed into cold storage. We examined fruit for firmness, soluble solids contents, anthocyanin concentrations, total phenolic compounds, flavonoid concentrations, ascorbic acid content, antioxidant activity, phenylalanine ammonia-lyase and superoxide dismutase activities. Figs coated with Aloe vera gel maintained higher firmness, anthocyanin concentrations, total phenolic compounds, flavonoid concentrations, ascorbic acid content, and antioxidant capacity than the control. Phenylalanine ammonia-lyase and superoxide dismutase activities were enhanced with Aloe vera gel treatments. The results showed that Aloe vera gel treatments could be an alternative to the current chemical protocols for preserving nutraceutical traits of fig fruit by maintaining antioxidant capacity during storage.

Cosmic ray modulation in the heliosphere
Creators: name: Baker, Christopher Paul
Publisher: name: University Of Tasmania
Year: 2023

description: Models describing the modulation of galactic cosmic rays in the heliosphere have been developed and investigated. These models are numerical solutions of the cosmic ray transport equation under idealized heliospheric conditions. Primarily, the models were used to predict the radial gradient g r of galactic cosmic rays in the vicinity of the Earth during solar-minimum conditions specified by a flat neutral sheet and no propagating shock disturbances. It was found that g r was not sensitive to the assumed value of the cosmic ray distribution at the Sun, but was very sensitive to (a) the diffusion coefficients used to specify the rate of diffusion of the cosmic ray distribution near the Sun, and (b) the choice of the integrating algorithm used to determine the distribution from the transport equation. The stability of each integrating algorithm used was also investigated. There have been many measurements of the value of g,. at Earth in the past, mainly derived from data collected by polar-based neutron monitors or detectors on board satellites. From all sources of data and over a wide range of energy (tens of MeV to ~100 GeV) the general consensus is that g,. at Earth is less than 5% AU-1 and probably around 1-2 % AU-1 . The models investigated in this thesis predict a gradient in this range but only if certain diffusion coefficients are specified. The models were also used to investigate the relative importance of shocks, or propagating solar disturbances, to the total eleven year cycle of cosmic ray modulation for medium energy (1-10 GeV) particles. It was found that such disturbances were unable to produce the observed intensity difference seen from solar minimum to solar maximum. It was concluded that these, and higher energy particles, are modulated significantly by changes in the overall global average heliospheric magnetic field through bulk drift motion. An example of this bulk-drift modulation was investigated by looking at the correlation of neutral-sheet position with isotropic intensity wave variations seen in the cosmic ray data. For this analysis, a generalized model of the neutral sheet was developed.. An independent measurement of g r was also calculated from data collected by the network of cosmic ray detectors operated by the Hobart cosmic ray group during the years 1975-78 and 1982-85. This group consists of the Cosmic Ray Section of the Australian Antarctic Division and the Cosmic Ray Section of the University of Tasmania (Physics Department). The gradient g r was determined by applying a north-south anisotropy analysis to the data. The value of g r obtained was sensitive to the assumed energy spectrum of the north-south anisotropy but was not inconsistent with other experimentally determined values. The gradient was generally less than 5% AU -1 . It was necessary to calculate coupling coefficients and atmospheric correction coefficients for the Mawson muon telescopes in order to use the data from these detectors in the north-south anisotropy analysis.

description: The Color Glass Condensate is an effective theory description for the small momentum fraction x degrees of freedom in a high energy hadron or nucleus, which can be understood in terms of strong classical gluon fields. We discuss the resulting picture of the initial conditions in a relativistic heavy ion collision. We describe recent work to show that the leading logarithms of the collision energy can be factorized into the renormalization group evolution of the small x wavefunction. We then describe how this framework can be used to understand the long range rapidity correlations observed by the RHIC experiments.

description: This study evaluated the eﬀect of entomopathogens and plant extracts, used against Tuta absoluta, on growth, yield, and fruit quality of tomato. Two ﬁeld trials were carried out in a randomised compled block design, replicated thrice. The treatments were Steinernema sp. RW14­M­C2a­3, Steinernema sp. RW14­M­C2a­3, Metatech®WP (Metarhizium anisopliae, Strain FCM Ar 23B3), Beauvitech®WP (Beauveria bassiana, Strain J25) as entomopathogens, Tephrosia vogelii and Phytolacca dodecandra as plant extracts, and azadirachtin 0.03% EC. Imidacloprid and water also were included as positive and negative controls, respectively. The best growth and yield parameters were recorded with the entomopathogens and azadirachtin, which were insigniﬁcantly diﬀerent in most cases. The increase in yied of healthy fruit per plant (average of two trials) compared to the negative control (water spray) was 11.4, 10.8,10.1, 9.6, 3.96, 2.2, 11.7 and 2.4 folds for Steinernema sp. RW14M­C2a­3, Steinernema sp. RW14­M­C2a­3, Metatech®WP, Beauvitech WP, T. vogelii, P. dodecandra, azadirachtin, and imidacloprid, respectively. There was no signiﬁcant diﬀerence in number of leaves per plant and fruit quality parameters. The entomopathogens and azadirachtin, which exhibited a capacity to enhance tomato growth and reduced yield losses due to T. absoluta, are recommended to be included in integrated pest management programme on tomato.

description: Since there is a hypothesis that qualitative and/or quantitative differences of specific proteins may be associated with morphological variants in cacti of the Cereus genus (phenotypes erect, tortuosus and monstruosus), in current study we tested three different methods for protein extraction from shoots of the phenotypic variants to obtain protein fractions for further proteomic analysis. The TCA/acetone method for protein extraction revealed a larger number of well-defined bands in SDS-PAGE system than the methods with phenol. The quantification of protein extracted by TCA/acetone ranged between 0.488 (tortuosus) and 2.92 µg·mL-1 (monstruosus). Although the use of phenol is the most appropriate procedure for protein extraction from recalcitrant tissues, results have shown that extraction buffer containing two antioxidant agents (EDTA and β-mercaptoethanol) and PMSF to prevent protein degradation was efficient to avoid proteolysis and lower protein yield, than using TCA/acetone precipitation for protein extraction from shoots of Cereus sp. The use of extraction buffer with appropriate combinations of antioxidant agents, phenol-complexing agents, and protease inhibitors may be an efficient alternative for proteins extraction from succulent and recalcitrant tissues (such as cactus plants) using a simple protein extraction method.

Double Helicity Dependence of Jet Properties from Dihadrons in Longitudinally Polarized p+p Collisions at sqrt(s) = 200 GeV

description: It has been postulated that partonic orbital angular momentum can lead to a significant double-helicity dependence in the net transverse momentum of Drell-Yan dileptons produced in longitudinally polarized p+p collisions. Analogous effects are also expected for dijet production. If confirmed by experiment, this hypothesis, which is based on semi-classical arguments, could lead to a new approach for studying the contributions of orbital angular momentum to the proton spin. We report the first measurement of the double-helicity dependence of the dijet transverse momentum in longitudinally polarized p+p collisions at sqrt(s) = 200 GeV from data taken by the PHENIX experiment in 2005 and 2006. The analysis deduces the transverse momentum of the dijet from the widths of the near- and far-side peaks in the azimuthal correlation of the dihadrons. When averaged over the transverse momentum of the triggered particle, the difference of the root-mean-square of the dijet transverse momentum between like- and unlike-helicity collisions is found to be -37 +/- 88(stat) +/- 14(syst) MeV/c.

description: We examine the theoretical limits of the generation of entanglement in a damped coupled ion-cavity system using jump-based feedback. Using Raman transitions to produce entanglement between ground states reduces the necessary feedback bandwidth, but does not improve the overall effect of the spontaneous emission on the final entanglement. We find that the fidelity of the resulting entanglement will be limited by the asymmetries produced by vibrations in the trap, but that the concurrence remains above 0.88 for realistic ion trap sizes.

title: Daughters of Charity: Catholic Women and Their Communities in Antebellum America
Creators: name: McCubbins, Linda Merritt
Publisher: name: Old Dominion University Libraries
Year: 1999

description: This study calls into question common assumptions about the limited public role of Catholic women during the antebellum period of American history. To understand the roles Protestant women played during this era, it is important to understand Catholic women's roles. Through primary and secondary source documents, the similarities and differences relating to church structure and theology will be documented. The study will also examine reasons why Protestant women converted to Catholicism during a profoundly anti-Catholic era.

In the late eighteenth and early nineteenth centuries, women, both Catholic and Protestant, played an increasingly public role through organized benevolence and other activities. In a time when there was insufficient social welfare, the roles women played were important as poverty, sickness, and death began to reach crisis proportions. Women's benevolent and other activities were often organized through churches. This thesis suggests that Catholicism and Protestantism both supported and subverted traditional gender roles, and aided the emergence of a new feminine ideal. This ideal was an extension of the more activist components of the traditional female roles of mother and wife.

Spin dependent electron screening is the fundamental mechanism at the microscopic level. We also predict an electric control of magnetization in this structure. The naturally broken inversion symmetry in our tri-component structure introduces a magnetoelectric coupling energy of $P M^2$. Such a magnetoelectric coupling effect is general in ferromagnet-ferroelectric heterostructures, independent of particular chemical or physical bonding, and will play an important role in the field of multiferroics.

In this proceeding paper it is shown that, if advanced projects on the detection of Gravitational Waves (GWs) will improve their sensitivity, allowing to perform a GWs astronomy, accurate angular and frequency dependent response functions of interferometers for GWs arising from various Theories of Gravity, i.e. General Relativity and Extended Theories of Gravity, will be the ultimate test for General Relativity.

description: Aims. The mobility of H atoms on the surface of interstellar dust grains at low temperature is still a matter of debate. In dense clouds, the hydrogenation of adsorbed species (i.e., CO), as well as the subsequent deuteration of the accreted molecules depend on the mobility of H atoms on water ice. Astrochemical models widely assume that H atoms are mobile on the surface of dust grains even if controversy still exists. We present here direct experimental evidence of the mobility of H atoms on porous water ice surfaces at 10 K. Methods. In a UHV chamber, O2 is deposited on a porous amorphous water ice substrate. Then D atoms are deposited onto the surface held at 10 K. Temperature-Programmed Desorption (TPD) is used and desorptions of O2 and D2 are simultaneously monitored. Results. We find that the amount of O2 that desorb during the TPD diminishes if we increase the deposition time of D atoms. O2 is thus destroyed by D atoms even though these molecules have previously diffused inside the pores of thick water ice. Our results can be easily interpreted if D is mobile at 10 K on the water ice surface. A simple rate equation model fits our experimental data and best fit curves were obtained for a D atoms diffusion barrier of 22(+-)2 meV. Therefore hydrogenation can take place efficiently on interstellar dust grains. These experimental results are in line with most calculations and validate the hypothesis used in several models.

description: After an overture and a non-technical exposition of the relevant theoretical framework including a brief discussion of some of the most popular extensions of the Standard Model, we will compile a list of 20 goals in flavour physics that could be reached already in the next decade. In addition to K, D and B_{s,d} decays and lepton flavour violation also flavour conserving observables like electric dipole moments of the neutron and leptons and (g-2)_μare included in this list. Flavour violation in high energy processes is also one of these goals. Subsequently we will discuss in more detail the most urgent issues for the coming years in the context of several extensions of the Standard Model like models with Minimal Flavour Violation, the general MSSM, the Littlest Higgs Model with T parity, Randall-Sundrum models and supersymmetric flavour models. This presentation is not meant to be a comprehensive review of flavour physics but rather a personal view on this fascinating field and an attempt to collect those routes that with the help of upcoming experiments should allow us to reach a much deeper understanding of physics, in particular flavour physics, at very short distance scales.

St. Mary's College and the Friends School, compared from their students' perspectives, 1940-1993
Creators: name: Clarke, JW
Publisher: name: University Of Tasmania
Year: 2023

description: My general line of inquiry started with the fact that I am interested in the effects of school life on individuals lives and values, and also how/why perceptions of school vary within groups and between groups, also between different schools. I chose St. Mary's College and The Friends School because I am interested in their educational and religious philosophies and practices and also because I am an ex-student of St. Mary's College and currently teach there. An important part of my research would be how students, as adults, perceived their school and what effect its values have had on their lives. A related aim of this thesis, was to discover in what ways the schools have maintained their particular philosophies in the twentieth century in the eyes of the men and women who were students from 1924 - 1993. I chose as my main research method an approach to past students of both schools via a questionnaire and interviews for two reasons: a) My intention to evaluate students' own perceptions of their school rather than make an 'external' evaluation via primary and secondary written sources. b) A second factor was the lack of archival material for St. Mary's College. Very few documents detailing school administration, enrolments and academic results have survived. On the other hand, The Friends- School's history is very well documented. In order to allow a reasonable comparison between the schools, I had to start from the same 'base' in each school in terms of sources. This approach suited my aims in both respects - it provided direct evidence of students' perceptions of their schools and allowed a 'level playing field' in terms of research material.
The re-worked fairy tale : an approach to teaching how fiction works
Creators: name: Bennett, Jillian
Publisher: name: University Of Tasmania
Year: 2023

description: By reading re-worked fairy tales - in picture books and woven into an apparent realist novel - to Year Five children and engaging them in conversations over an eight week period, I helped them to position themselves differently, and in so doing to see themselves differently, in that they began to become both critically and creatively aware of how structure and literary patterns contribute to meaning. I taped the children's talk and used their journal entries to evaluate the critical and creative nature of their responses in order to reflect on different ways in which I could intervene to help them become more aware. Whilst at times recording their talk was intrusive, it became evident that it was an effective way of analysing their responses. In the study, the re-worked fairy tales were used as a means of teaching how fiction works from a cultural perspective. The tales and the novel cited in the study are indicative of the change in narrative over the last thirty years and the gradual evolution in the ways stories are told, and the changing views of readers. The metafictive nature of these books emphasises its refusal to take for granted how stories are told. In using metafictional elements the writers/illustrators or \contemporary adaptors\" offer many cognitive and emotional opportunities for children to become aware and acute readers. During the programme the children were read a range of re-worked fairy tales by writers/illustrators which included Jon Scieszka Lane Smith Steve Johnson Roald Dahl and Tony Ross. As a result they began to understand the jokes in the mostly humorous tales where opposition occurs between normal expectations and some incongruous elements. As Kieran Egan points out \"A joke is not only funny; it is potentially another of those little factories of understanding a place where understanding can be made and expanded.\" (1986 p.86)"

description: The ongoing trends of rapid population growth, urbanization and climate change are bringing about a series of pressures upon Europe’s waters. As the one responsible for managing this vital resource, the water sector faces increasing challenges to deal with this task. Against this background, digital technologies open up a variety of opportunities for the different stakeholders involved in the water sector to take action. This document is inspired on the Quadruple Helix Model adopted by the European Union in its Open Innovation 2.0 policy approach. It follows the notion that the most adequate and operable solutions to the key challenges the water sector faces will emerge from the active involvement and collaboration between public administration, academia, business and civil society. Ultimately, this quadruple helix brief aims to expose fields of opportunity in which these four stakeholder types (helices) can get involved in ensuring a smooth and reasonable digital transition.

description: The dielectric susceptibility of a wide class of dielectric materials follows, over extended frequency ranges, a fractional power-law frequency dependence that is called the "universal" response. The electromagnetic fields in such dielectric media are described by fractional differential equations with time derivatives of non-integer order. An exact solution of the fractional equations for a magnetic field is derived. The electromagnetic fields in the dielectric materials demonstrate fractional damping. The typical features of "universal" electromagnetic waves in dielectric are common to a wide class of materials, regardless of the type of physical structure, chemical composition, or of the nature of the polarizing species, whether dipoles, electrons or ions.

Transit timing effects due to an exomoon

description: As the number of known exoplanets continues to grow, the question as to whether such bodies harbour satellite systems has become one of increasing interest. In this paper, we explore the transit timing effects that should be detectable due to an exomoon and predict a new observable. We first consider transit time variation (TTV), where we update the model to include the effects of orbital eccentricity. We draw two key conclusions: 1) In order to maintain Hill stability, the orbital frequency of the exomoon will always be higher than the sampling frequency. Therefore, the period of the exomoon cannot be reliably determined from TTV, only a set of harmonic frequencies. 2) The TTV amplitude is proportional to M_S a_S where M_S is the exomoon mass and a_S is the semi-major axis of the moon's orbit. Therefore, M_S and a_S cannot be separately determined. We go on to predict a new observable due to exomoons - transit duration variation (TDV). We derive the TDV amplitude and conclude that its amplitude is not only detectable, but the TDV signal will provide two robust advantages: 1) The TDV amplitude is proportional to M_S a_S^{-1/2} and therefore the ratio of TTV and TDV allows for a separate determination of M_S and a_S. 2) TDV has a 90 degrees phase difference to the TTV signal, making it an excellent complementary technique.

title: Regulatory Capture, the Chesapeake Bay, and Hampton Roads: What's on Your Plate
Creators: name: Gannon, Ronnie David
Publisher: name: Old Dominion University Libraries
Year: 2014

description: The Chesapeake Bay and its 64,000 square mile watershed are both severely impacted from excessive amounts of nutrient pollution, which contributes to a growing presence of dead zones in the Bay. What causes nutrient pollution? What are dead zones? In addition, many of the Bay's commercially valuable species of marine life have been/ are overexploited to the point of collapse / verge of collapse. Despite all of these facts, management agencies continue to weakly enforce regulations. Why?

Not to mention, much of the Bay's marine life is unsustainably caught in the contaminated waters of Hampton Roads. How, and for what? From past to present, there has been many lingering ideologies of colonialism that have impacted the health of the Chesapeake Bay and its fisheries. With the Bay's overall health being severely out of equilibrium, how can unsustainable environmental practices continue to thrive in and around the Chesapeake Bay?
The HD 40307 Planetary System: Super-Earths or Mini-Neptunes?

description: Three planets with minimum masses less than 10 Earth masses orbit the star HD 40307, suggesting these planets may be rocky. However, with only radial velocity data, it is impossible to determine if these planets are rocky or gaseous. Here we exploit various dynamical features of the system in order to assess the physical properties of the planets. Observations allow for circular orbits, but a numerical integration shows that the eccentricities must be at least 0.0001. Also, planets b and c are so close to the star that tidal effects are significant. If planet b has tidal parameters similar to the terrestrial planets in the Solar System and a remnant eccentricity larger than 0.001, then, going back in time, the system would have been unstable within the lifetime of the star (which we estimate to be 6.1 +/- 1.6 Gyr). Moreover, if the eccentricities are that large and the inner planet is rocky, then its tidal heating may be an order of magnitude greater than extremely volcanic Io, on a per unit surface area basis. If planet b is not terrestrial, e.g. Neptune-like, these physical constraints would not apply. This analysis suggests the planets are not terrestrial-like, and are more like our giant planets. In either case, we find that the planets probably formed at larger radii and migrated early-on (via disk interactions) into their current orbits. This study demonstrates how the orbital and dynamical properties of exoplanet systems may be used to constrain the planets' physical properties.

The distribution and abundance of the intertidal prosobranchs Littorina scutulata (Gould 1849) and L. sitkana (Philippi 1845)
Creators: name: Behrens, Sylvia
Publisher: name: University of British Columbia

description: An attempt was made to explain the distribution and abundance of the intertidal prosobranch snails Littorina scutulata (Gould, 1649), and L. sitkana (Philippi, 1845) on beaches near the city of Vancouver, in the Gulf Islands and on the west coast of Vancouver Island, British Columbia. L. scutulata has a planktonic dispersal stage and is widely distributed. L. sitkana develops directly from benthic egg masses and tends to be more restricted in its distribution. The egg masses of L. sitkana are susceptible to desiccation at low tide, and consequently this species thrives best in damp places such as mud flats, tide pools and crevices. L. sitkana appears to be selected against in wave-swept places, because it offers more resistance to wave action than does the comparatively streamlined L. scutulata. Experimental manipulation of densities and species composition indicated that food limitation may take place in the summer (decreased growth rates at higher densities of snails and low food abundance) but not in the winter. Density dependent survivorship and natality were found for L. sitkana, indicating that a regulatory mechanism may be operating. L. scutulata showed no such density dependent response at the densities examined. The presence of L.scutulata reduced the survival of L. sitkana and vice versa in comparison to control populations consisting of each species alone. Possible evolutionary survival strategies and competitive relationships of these two species are discussed.

description: Hospitals faced unprecedented demand during the COVID-19 pandemic, which significantly impacted their ability to efficiently allocate resources and ensure timely patient access to care. To assess hospital accessibility in Texas, we measured hospital drivetime access using publicly available weekly hospitalization rates, staffed bed supply, and demand during the pandemic. We utilized private hospital inpatient records from the Texas Department of Health and Human Services to determine the likely ZIP code origin of patients and estimate their drive times to care (cost). These estimates represent the cost of accessing care based on proximity, taking into account events such as traffic congestion and road conditions. Using Python’s geopandas library, we implemented the Enhanced Two-Step Floating Catchment Area (E2SFCA) and the Two-Step Floating Catchment Area (2SFCA) model. These models estimate patient flow and hospital access scores by analyzing fluctuations in the relationship between hospital supply and patient demand on a weekly basis. We compared how these scores change based on variations in available hospital beds, patient population density, and weekly demand. these models to assess their predictive accuracy in patient hospital choice. The results revealed that access is influenced by the proximity of patients to hospitals and estimating demand is important in the allocation of resources. The results from this study can be used to inform healthcare decision-making during times of increased patient volume, such as during pandemics, by identifying areas of high demand with limited resources. Future work will aim to refine this model by using more detailed cost matrices, testing it on other states, and applying it over longer periods of time.
