description: The objective of the present work is to study a cosmological model for a spatially flat Universe whose constituents are a dark energy field and a matter field which includes baryons and dark matter. The constituents are supposed to be in interaction and irreversible processes are taken into account through the inclusion of a non-equilibrium pressure. The non-equilibrium pressure is considered to be proportional to the Hubble parameter within the framework of a first order thermodynamic theory. The dark energy and matter fields are coupled by their barotropic indexes, which are considered as functions of the ratio between their energy densities. The free parameters of the model are adjusted from the best fits of the Hubble parameter data. A comparison of the viscous model with the non-viscous one is performed. It is shown that the equality of the dark energy and matter density parameters and the decelerated-accelerated transition occur at earlier times when the irreversible processes are present. Furthermore, the density and deceleration parameters and the distance modulus have the correct behavior which is expected for a viable scenario of the present status of the Universe.

description: Electric vehicles (EVs) are gaining momentum across the globe as a strategy to combat climate change, however, uncontrolled charging of EVs can create pressure on electricity grid. Along with smart charging (V1G), Vehicle-to-grid (V2G) technology presents an opportunity for a new way of vehicle grid integration that enables EVs to send electricity back to the grid, creating the potential for EVs to provide grid services including electricity generation as well as regulation up and regulation down capacity. This study aims to quantify the economic value of V2G in the 2025 and 2030 California grid using an EV simulation model and a grid Unit Commitment Economic Dispatch model. Scenarios on different renewable penetration and battery cost are included to account for uncertainty in future energy and battery development. Results show a V2G-enabled EVs can generate an average of $32-$48 more total annual net revenue than V1G, most profits come from EVs providing electricity and a small amount from regulation down capacity. From 2020 to 2030, the economic value of V1G and V2G increased, the result also shows a tradeoff exists between renewable deployment and V2G value. V2G can generate a moderate amount of economic benefit given access to electricity and ancillary service wholesale market, which need further policy support and third-party business cases.
title: V-A mycorrhizas of winter cereals in S.E. England: Ecology, taxonomy and effects of agrochemicals
Creators: name: Dodd, John Charles
Publisher: name: University of Kent
Year: 2023

description: The association between vesicular-arbuscular mycorrhizal fung and winter wheat was investigated in the field, the greenhouse and the laboratory. Extensive early autumn fractional infection of commercially grown winter cereals was observed in two fields in Sussex over a three-year period. Fluctuations in seasonal infection levels were monitored over this period and two trends were noted in different seasons, an overwinter decline and continued infection spread through the winter months. The overwinter decline in infection may be correlated with low thermal time accumulation during the autumn period and therefore early sowing may be important. This effect, however, appeared to be influenced by other factors such as soil moisture status and consequently root growth dynamics. Three Glomus species were obtained in pure pot culture and their taxonomy investigated by means of morphology (light microscopy and electron microscopy) and polyacrylamide gel electrophoresis of spore esterases. Differences were noted between spores isolated from the field and their subsequent appearance in pure pot cultures. The effect of soil pesticides on the VAM symbiosis was investigated. In general, herbicide applications at equivalent field rates had negligible effects on VAM infection development in winter wheat grown in pots in the greenhouse, and on in vitro spore germination. Fungicide applications, also at equivalent field rates, covered the range of response from inhibitory to stimulatory on infection levels and spore germination depending on the nature of the active moiety of the agrochemical used. The indigenous VAM population from one of the Sussex field sites appeared less efficient at stimulating phosphorus uptake in winter wheat grown in partially sterile field soil compared with three introduced Glomus endophytes. Root and rhizosphere acid phosphatase activities differed between three VAM fungal infections of wheat grown in sterile sand culture. High activity did not correlate with increased shoot P uptake.

description: Anthropogenic soils are becoming more prominent across the globe, often seen in urban areas, and ecological soil management presents an opportunity to shift from big business to ecosystem services focusing on local food provision, stormwater management, etc., and resident autonomy, highlighting the need to alleviate continued degradation on urban soils. Among many agricultural soil amendments biochar, a form of charcoal, has numerous favorable qualities including water storing capabilities, plant nutrients retention, and carbon sequestration, as well as potentially positive impacts on soil microbial communities. The particle sizes of biochars vary greatly, and little consensus exists on what size, if any, explains best optimization of biochar functions in soil and what effects this application may have on soil fauna and the processes they carry out. The effect of biochar application on soil invertebrates, specifically arthropods, have not been thoroughly investigated despite increasing recognition that soil fauna, micro-, meso-, and macro- all play key roles in soil health and quality. In this study, we applied 3 distinct particle size distributions of biochar together with compost in treatments across 64 plots. We collected soil invertebrates using pitfall traps to determine faunal responses to biochar application rate and particle size after an initial growing season. We saw significant results in moisture depending on biochar treatment with Mixed showing the highest and Small particles appearing to account for the effects more than Large. Other results suggest no significant difference in faunal responses, specifically relative abundance, diversity, and community composition, to the first season of biochar application. Species richness analysis suggests there are marginally significant trends towards a certain particle size, with Small (sieved; <1mm) treatments collecting the most invertebrates and Mixed (unsieved) treatments suggesting below ground influences, which may also be seen with biomass. This study provides key metrics needed to inform ecological management using biochar, and serves as a model for urban ecology literature, and a model for testing hypotheses about invertebrate community responses to biochar application in urban agricultural settings.

description: Anthropogenic climate change is disrupting ecological and human systems worldwide, particularly across the tropics. A complete transformation of our energy and food systems is necessary. We must aggressively phase out fossil fuels and dramatically reduce the current levels of atmospheric CO2 to avoid disaster. The 2018 IPCC Report acknowledges that to stay under the 1.5 degrees of warming target, carbon dioxide removal (CDR) must be employed. Unfortunately, most proposed CDR projects center around expensive and energy-intensive industrial-chemical processes. Instead, we hope that this research can contribute to the growing amount of scholarly research of biological carbon sequestration through smallholding agricultural management and energy microgrids. The motivation behind this research is to understand the potential between coffee agroecosystems, smallholder farming, and climate change mitigation. Current research shows evidence that smallholder management of coffee agroecosystems is linked to increased biodiversity (Richard & Mendez, 2013; Perfecto et al., 2014; Goodall et al., 2015). However, the results are mixed for its potential for carbon sequestration and climate change mitigation (Schmitt-Harsh et al., 2012; Richard & Mendez, 2013; Goodall et al., 2015; Tumwebaze & Byakagaba, 2016). This study explores the sustainable management of coffee agroforests using biochar and biomass energy to store soil carbon and provide decentralized energy in rural and farming communities in Puerto Rico. This work is divided in two chapters. In Chapter 1, we examine the relationship between shade management in coffee agroforestry, and the availability of downed woody material (DWM), and its potential as feedstock for energy production. We estimate total biomass of DWM from sampling twenty coffee farms across a shade gradient in the central mountains of Puerto Rico using line transects. We then compare the average amount of DWM found in each farm and the amount of shade measured at two levels (at breast height and above the highest coffee bush). Using the data obtained in the field survey, we estimate the potential for electricity generation per year using DWM from coffee agroforests in Puerto Rico and the potential for reduction in carbon emissions from the production of biochar. In Chapter 2, we study a greenhouse experiment using biochar to understand its effects on plant growth of coffee (Coffea arabica). Using coffee seedlings grown in different mediums consisting of compost, soil, and biochar mixtures, we track height, number of leaves, and length of the longest leaf of each seedling for three consecutive months to understand the potential effect of biochar as a soil amendment. This study was the first part of a broader project with our local partner Casa Pueblo. This self-management organization owns a small coffee farm where the seedlings were transplanted for the next phase of this project.
Superstatistics as the statistics of quasi-equilibrium states: Application to fully developed turbulence

description: In non-equilibrium states, currents are produced by irreversible processes that take a system toward the equilibrium state, where the current vanishes. We demonstrate, in a general setting, that a superstatistics arises when the system relaxes to a (stationary) quasi-equilibrium state instead, where only the \textit{mean} current vanishes because of fluctuations. In particular, we show that a current with Gaussian white noise takes the system to a unique class of quasi-equilibrium states, where the superstatistics coincides with Tsallis escort $q$-distributions. Considering the fully developed turbulence as an example of such quasi-equilibrium states, we analytically deduce the power-law spectrum of the velocity structure functions, yielding a correction to the log-normal model which removes its shortcomings with regard to the decreasing higher order moments and the Novikov inequality, and obtain exponents that agree well with the experimental data.

description: The problem of conversion of experimentally measured luminescence spectrum into the absorption cross section is revisited. The common practice of using the van Roosbroeck-Shockley (or Kubo-Martin-Schwinger or Kennard-Stepanov) relation in this context is incorrect because luminescence from semiconductors is essentially all due to the spontaneous emission component of the recombination of carriers distributed far-from-equilibrium. A simple, physically consistent, and practical prescription for converting the luminescence spectra into absorption is presented and its relation to the so-called nonequilibrium generalization of the van Roosbroeck-Shockley relationship is discussed.

description: Coastal areas are more sensitive to climate change and are more vulnerable to increase in temperatures. For the last decades, residents of New Orleans have been experiencing hotter summer temperatures conditions and extreme weather conditions. Meanwhile, with economic development and the impact of human activities, the land cover of the region has experienced substantial changes. Since Hurricane Katrina in 2005, Parks and Parkway has undertaken a re-greening effort to replace the many thousands of trees lost. A specific benefit of tree cover is its ability to reduce the heat storage capacity of urban surfaces that creates urban heat islands. This study (1) creates an up-to-date, high spatial resolution land cover map and examine how the components of Land cover, particularly trees vary across post-Katrina New Orleans; (2) quantifies the magnitude and seasonality of LST change between 2006 to 2020 within the same areas of Land cover maps; and (3) contextualizes Land cover and LST patterns with census‐based demographic data and to draw inferences about the heat vulnerability implications.

description: This study identified formation time, movement and disappearance of spring thermal bars in southeast Lake Michigan off Muskegon from 2010 to 2019, and analyzed 2019 and 2015 zooplankton distribution and composition in response to thermal bar dynamics and environmental characteristics. Thermal bar location was identified using available Sea Surface Temperature satellite data. Analysis of zooplankton biomass and composition distribution with environmental characteristics used data from NOAA and Great Lakes Environmental Laboratories research programs. Analysis used generalized linear models. Results showed that thermal bars formed mainly in April, persisted one to four weeks, and formation and movements influenced by air temperature occurred later with cooler air. Location relative to shore was positive and significantly influenced by runoff and air temperature 7 days prior to the thermal bar identification, but not significantly influenced by air temperature on the day bars were identified. Movement rate towards offshore, ranging 0 to 3.53 cm/s, increased significantly with air temperature 10 days prior to the end of thermal bar movements and with distance to shore but was not significantly related to river runoff discharge. Zooplankton biomass significantly varied among zones relative to thermal bars along the Muskegon transect and was higher in zones inshore from thermal bars. Chlorophyll a (CHL) biomass was highest nearshore from thermal bars with highest colored dissolved organic matter (CDOM) and water temperature. Zooplankton biomass distribution was consistent with CHL, water temperature and CDOM distribution. Zooplankton composition also varied among areas relative to thermal bars. In 2015, Leptodiaptomus sicilis copepod was most abundant in nearshore areas in April and near thermal bars with preferred cooler temperatures in May. In 2019, L. sicilis and L. ashlandi were most abundant near thermal bars in April, but decreased in May as cyclopoid copepod Diacyclops thomasi became more abundant.

description: The struggle to conserve endangered species is often framed as military or punitive legislative and policy action. We worked with The Last Animals Foundation (TLAF), formed from Kate Brook’s documentary, to change that framing, using the film to advance environmental education and formalize data visualization tools. We structure our materials according to Paolo Freire’s levels of relational knowledge production outlined in Pedagogy of the Oppressed. (1) For young learners, through literature review and consultation with multiple partners in the U.K. and Indonesia, we synthesized environmental education policies, the educational use of films, and conservation priorities in the Leuser ecosystem in Indonesia. That synthesis informed the development of a curriculum that builds secondary school students’ understanding of wildlife conservation and related environmentally sustainable career options . (2) For the media and an engaged public, we developed a case study sharing tactics that fostered increased global impact for the film, using ESRI’s StoryMaps. Users immerse themselves in the film’s story, learn about outreach work, and see the result of that work in the forms of public engagement (through interactive maps) and policy outcomes (through explanations and videos). (3) For specialists and scientists, we partnered with a team of U.S. and foreign government agencies led by prominent conservation biologist Dr. Samuel Wasser to produce an ivory seizure network application to assist in prosecuting the heads of transnational crime organizations driving elephant poaching and the ivory trade. This work is in review at a prominent scientific journal and being presented at international conferences.

description: A Hybrid Physical-Chemical Vapour Deposition (HPCVD) system consisting of separately controlled Mg-source heater and substrate heater is used to grow MgB2 thin films and thick films at various temperatures. We are able to grow superconducting MgB2 thin films at temperatures as low as 350 C with a Tc0 of 35.5 K. MgB2 films up to 4 um in thickness grown at 550 C have Jc over 10E6 A/cm2 at 5 K and zero applied field. The low deposition temperature of MgB2 films is desirable for all-MgB2 tunnel junctions and MgB2 thick films are important for applications in coated conductors.
The influence of molecular ion characteristics on room temperature ionic liquid structure and transport properties
Creators: name: Spohr, Heidrun Veronika
Publisher: name: University of British Columbia
Year: 2010

description: Room temperature ionic liquids (RTILs) are pure, organic salts, that are liquid at ambient temperatures. RTILs are highly customizable, with a wide choice of ion types and varying substituents. The customizability of RTILs also poses the greatest challenge, rational design of liquid properties from molecular structure. The influence of RTIL ion characteristics on liquid structure and transport properties is systematically investigated employing molecular dynamics simulations. The characteristics investigated include size disparity, ion charges that are displaced from the center of mass, and variation of the cation-anion charge separation σ'(+−). Different simple spherical ionic liquid models are developed that isolate each of these characteristics. Statistical mechanical analysis shows that more size disparate models have decreased coordination numbers, the diffusion coefficients and electrical conductivity increase, and the viscosity decreases. The effects of size disparity can be canceled to a large extent by decreasing σ'(+−). An increasing displacement of the ion charge leads to the formation of directional ion pairs of increasing strength. Weak pairing results in non-uniform ion distributions and reduced caging, with similar liquid property trends as size disparate systems. A large charge displacement and short σ'(+−) leads to increasing numbers of strong, long-lived directional ion pairs that dominate the liquid behavior. Increasing viscosities and decreasing electrical conductivities are observed in this regime. The temperature behavior of the ionic liquid models deviates from linear Arrhenius behavior, especially for the conductivity. The relationship between diffusion and viscosity conforms to the fractional Stokes-Einstein equation. The qualitative conclusions of our calculations suggest the utilization of ions with moderate charge displacement, and large size disparities, for desired low-viscosity RTILs with large ion mobilities. Mixtures of water with ionic liquid models generally show increased diffusion coefficients and electrical conductivities, and decreased viscosities. The increased mobility of the ions can be mainly ascribed to dynamical effects due to light water replacing heavy ions in the ion coordination shell. We observe deviating behavior when water can form strong, directional interactions with at least one ion, in the case of small, or of strongly charge displaced ions. In both cases the viscosity increases with increasing water concentration.

description: Multiple techniques are used to extract physiological signals from the human body. These signals provide a reliable method to identify the physical and mental state of a person at any given point in time. However, these techniques require contact and cooperation of the individual as well as human effort for connecting the devices and collecting the needed measurement. Moreover, these methods can be invasive, timeconsuming, and infeasible in many cases. Recent efforts have been made in order to find alternatives to extract these measurements using noncontact and efficient techniques. One of these alternatives is the use of thermal cameras for health monitoring. Our work explores reliable methods for extracting respiration rate, skin temperature and heart rate from thermal video. These methods leverage a combination of image processing and signal processing techniques in order to extract and filter physiological signals from the thermal domain. Finally, we review the use of thermal imaging in several applications, such as deception detection, stress detection and emotion recognition.

We find that such scenario is plausible and explains most of the features of the RZ 2109 spectrum (line luminosity, absence of H emission lines, peculiar asymmetry of the line profile); on the other hand, it requires the nova ejecta to be relatively massive (>~ 0.5e-3 Msun}), and the nova to be located at a distance

description: The antiperiodic transfer matrix associated to higher spin representations of the rational 6-vertex Yang-Baxter algebra is analyzed by generalizing the approach introduced recently in [1], for the cyclic representations, in [2], for the spin-1/2 highest weight representations, and in [3], for the spin 1/2 representations of the reflection algebra. Here, we derive the complete characterization of the transfer matrix spectrum and we prove its simplicity in the framework of Sklyanin's quantum separation of variables (SOV). Then, the characterization of local operators by Sklyanin's quantum separate variables and the expression of the scalar products of separates states by determinant formulae allow to compute the form factors of the local spin operators by one determinant formulae similar to the scalar product ones. Finally, let us comment that these results represent the SOV analogous in the antiperiodic higher spin XXX quantum chains of the results obtained for the periodic chains in [4] in the framework of the algebraic Bethe ansatz.

description: This report discusses the history and methods of the National Marine Fisheries Service’s (NMFS) longline surveys of the Gulf of Alaska, eastern Bering Sea, and eastern Aleutian Islands and summarizes the 1990-2014 survey results. The primary purpose of the NMFS longline survey is to determine the relative abundance and length composition of sablefish, Anoplopoma fimbria; shortspine thornyhead, Sebastolobus alascanus; rougheye rockfish, Sebastes aleutianus; blackspotted rockfish, Sebastes melanostictus; and shortraker rockfish, Sebastes borealis, in the Gulf of Alaska, eastern Bering Sea, and Aleutian Islands region. Only the abovementioned species and arrowtooth flounder, Atheresthes stomias, are discussed in this report. Catch results are listed for Pacific cod, Gadus macrocephalus; Pacific halibut, Hippoglossus stenolepis; giant grenadier, Albatrossia pectoralis; Greenland turbot, Reinhardtius hippoglossoides; spiny dogfish, Squalus acanthias; and Pacific sleeper shark, Somniosus pacificus. The survey area covers the upper continental slope and selected gullies of the Gulf of Alaska and the upper continental slope of the eastern Bering Sea and Aleutian Islands region. Overall sablefish abundance indices (relative population number (RPN) and relative population weight (RPW)) for the Gulf of Alaska decreased from 1990 to 2014. Shorrtspine thornyhead RPN for the Gulf of Alaska increased from 1990 to 2014 and RPW increased from 1990 to 2014. Rougheye and blackspotted rockfish RPN for the Gulf of Alaska increased from 1992 to 2014 and RPW increased from 1992 to 2014. Gulf of Alaska RPN for shortraker rockfish increased from 1992 to 2011 followed by a decrease during 2012-2014. While shortraker rockfish RPWs fluctuated over the years there was an overall increase in RPWs from 1992 to 2014. Arrowtooth flounder RPN for the Gulf of Alaska fluctuated between increases and decreases from 1990 to 2010 but decreased during 2011-2014. Arrowtooth flounder RPW decreased overall from 1990 to 2014.

The defining properties of these spaces are formulated in terms of the first curvature tensor of Cartan connection. The following three results constitute the main object of the present paper: 1. A concircularly flat Finsler manifold is necessarily of constant curvature (Theorem A); 2. Every $R^h$-recurrent Finsler manifold is concirculaly recurrent with the same recurrence form (Theorem B); 3. Every horizontally integrable concircularly recurrent Finsler manifold is $R^h$-recurrent with the same recurrence form (Theorem C). The whole work is formulated in a coordinate-free form.

title: Becoming a female engineer: Sex role self concept and sex role attitudes in occupational choice and socialisation
Creators: name: Newton, Peggy D.
Publisher: name: University of Kent
Year: 2023

description: Previous research on women entering technology has focussed on eminent women in science, suggesting that they are distinguished by masculine characteristics and close relationships with their fathers. More recent research on women entering non traditional occupations has suggested the importance of the mother as a role model in career choice and socialisation. The present research explored sex role self concept and sex role attitudes in a longitudinal study of two groups of young women being trained as technicians in engineering. Female engineers were compared with four groups: male engineers, female friends from school, women in business studies and women in nursery nursing. Regional comparisons were also made between subjects in London and in Birmingham. Measures used in the research were the Bern Sex Role Inventory and the MAFERR Inventory of Feminine Values. When they began training female engineers did not differ significantly from either their female friends or male engineers in their levels of perceived femininity or masculinity. However, female engineers (regions combined) were significantly more likely to be classified as androgynous than subjects in any other group and were significantly less likely to be classified to be classified as feminine sex typed than other female subjects. After two years' training, female engineers showed significant increases in femininity, and the differences between female and male engineers increased. Female engineers did not differ from their female friends or women in nursery nursing in their sex role attitudes and ideals; however, women in business studies had significantly more traditional attitudes than other female groups. As in previous research using the MAFERR, female engineers believed that men had a significantly more traditional view of an ideal woman than an ideal woman actually described by male engineers. Over time female engineers and women in business studies became significantly more profeminist in their sex role attitudes. Contrary to prediction, female engineers showed less dramatic changes in sex role self concept and sex role attitudes than women in business studies. Results of the experimental studies are discussed in terms of Bern's (1985) gender schema theory and several theories of attitude change. Practical implications of the research are explored, and suggestions are offered for how to recruit more female engineers.

description: We study FRW cosmology for a double scalar - tensor theory of gravity where two scalar fields are nonminimally coupled to the geometry. In a framework to study stability and attractor solutions of the model in the phase space, we constraint the model parameters with the observational data. For an accelerating universe, the model behaves like quintom dark energy models and predicts a transition from quintessence era to phantom era.

description: The KE inference system is a tableau method developed by Marco Mondadori which was presented as an improvement, in the computational efficiency sense, over Analytic Tableaux. In the literature, there is no description of a theorem prover based on the KE method for the C1 paraconsistent logic. Paraconsistent logics have several applications, such as in robot control and medicine. These applications could benefit from the existence of such a prover. We present a sound and complete KE system for C1, an informal specification of a strategy for the C1 prover as well as problem families that can be used to evaluate provers for C1. The C1 KE system and the strategy described in this paper will be used to implement a KE based prover for C1, which will be useful for those who study and apply paraconsistent logics.

description: Transferring a quantum state of a light field to a memory is of particular importance. However, this transfer is usually hampered because the memory system is subjected to some noise and this can limit the performance of the state transfer to a great extent. In this paper, we consider the transfer of a Gaussian state of light to a linear medium memory such as an opto-mechanical oscillator and propose a dynamical feedback controller that suppresses the noise in the memory system. To protect an unknown state, the feedback scheme employs the specific configuration of the quantum error correction; that is, a three-mode Gaussian state having appropriate syndromes is taken as the input. Correspondingly, the memory consists of three independent linear systems. The syndrome errors are estimated continuously in time through the measurement of the output field, and the results are then fed back to control the system. Because the input is Gaussian and the systems are all linear, it is possible to formulate the problem using the framework of the celebrated classical Kalman filtering and linear quadratic Gaussian control. A numerical simulation demonstrates the effectiveness of the control scheme.

description: Most recent results of $W$ boson mass measurements from Tevatron experiments (CDF and D0) in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ GeV are reported, using $0.2 fb^{-1}$ and $1.0 fb^{-1}$ data collected at CDF and D0, respectively. The measurements of $W$ boson properties at LHC experiments (ATLAS, CMS, and LHCb) in $pp$ collisions at $\sqrt{s}=7$ TeV, using data collected before Summer 2011, are presented. These measurements are essential at the preparation stage of the $W$ boson mass measurements at LHC. Challenges for $W$ mass measurement at the LHC in comparison with the Tevatron are outlined. Prospects for $W$ mass precision with upcoming measurements and its implications are discussed.

Self-assembly of oligomeric dipyrromethene metal complexes

description: The study of metallosupramolecular complexes has become an active research field in recent years. These complexes are formed through self-assembly processes driven by ligand-metal coordination, and they are widely used in molecular electronic, catalyst, host-guest chemistry and gas storage applications. Dipyrromethenes (dipyrrins) can act as monoanionic ligands which coordinate with various metals to form charge-neutral metal complexes. In the past decade, α,α’-linked and β,β’-linked bis(dipyrromethene)s have drawn considerable attention as building blocks for various supramolecular architectures. Surprisingly, limited work has been done to study meso-substituted dipyrrinato metal complexes. The primary objective of this project was to investigate meso-substituted dipyrrinato complexes and to synthesize novel meso-bridged bis(dipyrromethene) ligands to explore their capabilities for use in supramolecular systems. A new type of ligand which incorporates both boron-linked dipyrromethenes and free-base dipyrromethenes was synthesized and treated with various metals to form complexes. These metal complexes exhibit different structural features depending on the central metal or substituents on the dipyrromethenes, and the correlations between the structural features and optical properties were established. Also, a one-side BF₂-protected bis(dipyrromethene) ligand was used for stepwise oligomerization to form extended dipyrromethene arrays. Different methods to achieve these linear dipyrrin arrays were explored. Heteroleptic metal dipyrrin complexes can act as both the ligand and metal ion source to coordinate with free-base dipyrrin ligands, leading to the formation of oligomeric linear complexes incorporating the same or different metals. Further, differently angled spacers were employed to link two dipyrrin moieties at the meso-position. Depending on the angle of the spacer, the coordination reactions between bis(dipyrromethene)s and metals produced self-assembled cyclic oligomers with different core sizes. When the two dipyrrin moieties were oriented 86˚ apart, the resulting products ranged from trimer to hexamer. The trimeric and pentameric structures were determined by X-ray diffraction analysis, and the macrocycles display channel structures formed through intermolecular π-π or CH/π interactions. In contrast, when the two dipyrrin moieties were 35˚ apart, the main product was the dimer with trace amounts of tetramer. Finally, the coordination between linear heteroleptic metal dipyrrin complexes and the 35˚ angled bis(dipyrromethene) ligand produced a mixed-ligand complex.

description: The relative importance of metals and dust grains in the formation of the first low-mass stars has been a subject of debate. The recently discovered Galactic halo star SDSS J102915+172927 (Caffau et al. 2011) has a mass less than 0.8 Msun and a metallicity of Z = 4.5 10^{-5} Zsun. We investigate the origin and properties of this star by reconstructing the physical conditions in its birth cloud. We show that the observed elemental abundance trend of SDSS J102915+172927 can be well fitted by the yields of core-collapse supernovae with metal-free progenitors of 20 Msun and 35 Msun. Using these selected supernova explosion models, we compute the corresponding dust yields and the resulting dust depletion factor taking into account the partial destruction by the supernova reverse shock. We then follow the collapse and fragmentation of a star forming cloud enriched by the products of these SN explosions at the observed metallicity of SDSS J102915+172927. We find that [0.05 - 0.1] Msun mass fragments, which then lead to the formation of low-mass stars, can occur provided that the mass fraction of dust grains in the birth cloud exceeds 0.01 of the total mass of metals and dust. This, in turn, requires that at least 0.4 Msun of dust condense in the first supernovae, allowing for moderate destruction by the reverse shock. If dust formation in the first supernovae is less efficient or strong dust destruction does occur, the thermal evolution of the SDSS J102915+172927 birth cloud is dominated by molecular cooling, and only > 8 Msun fragments can form. We conclude that the observed properties of SDSS J102915+172927 support the suggestion that dust must have condensed in the ejecta of the first supernovae and played a fundamental role in the formation of the first low-mass stars.

description: Excerpts from the report; The breakage and damage of grocery products in warehousing, delivery, and store handling operations result in an estimated annual cost of over $35 million. Breakage and damage are reflected in lost sales, increased labor cost, and higher gross margin or lower net profit. The objective of this research was to determine the causes and the extent of breakage and damage to dry groceries in warehouses and retail food stores. The report shows the causes of damage and offers suggestions for eliminating them. The suggestions are presented in general terms because the time and costs involved in changing equipment or practices and measuring the effect of each specific suggestion were beyond the resources available for the study. This report also measures the direct and indirect costs of damage occurring in grocery warehouses, in transit, and at the retail store.
