REPURPOSING

description: Since 2008, Nammo Raufoss has heavily invested into the development of propulsion systems based on Hydrogen Peroxide (H2O2) as propellant for replacing more toxic solutions. Based on the promising development of these H2O2 systems, Nammo became part of another forward leaning project in 2017 through CNES and ESA for re-purposing the same RCS (Reaction Control System) technology for a reusable launcher named CALLISTO. In this paper a general description of the RCS for the Callisto reusable launcher demonstrator, the FCS/R, is presented. An update on the system is given together with an overall update on its components heritage. While having a reaction control system using H2O2 is not something novel, its application on a reusable launcher amplifies other design choices and considerations that need to go into the planning, especially design and operative issues related to the maintainability, and what scrutiny are needed to ensure that the concerns regarding reusability are accurately addressed in terms of failure detection, fault isolation, corrective action and operational verification .. These issues and concerns will be further examined and detailed in this paper.

description: In this work an alternative 3-dimensional aeroelastic beam finite element for rapid time-domain flutter analysis of non-uniform wings equipped with distributed trailing edge control surfaces is presented. The approach proposed takes advantage of Euler-Bernoulli and De Saint Venant beam theories. The aerodynamic loads, expressed in time domain, are directly incorporated in the beam element matrices that are computed from the governing equations weak form, resulting in a simple numerical tool that can be easily implemented in any beam-based finite element code. The method proposed is validated with commercial code aeroelastic results of non-uniform lifting structures with and without control surfaces.

description: We present the first experimental realization of coherent Bragg scattering off a one-dimensional (1D) system -- two strings of atoms strongly coupled to a single photonic mode -- realized by trapping atoms in the evanescent field of a tapered optical fiber (TOF), which also guides the probe light. We report nearly 12% power reflection from strings containing only about one thousand cesium atoms, an enhancement of two orders of magnitude compared to reflection from randomly positioned atoms. This result paves the road towards collective strong coupling in 1D atom-photon systems. Our approach also allows for a straightforward fiber connection between several distant 1D atomic crystals.

Quality in North Carolina Assisted Living Facilities: Legislative and Research Recommendations
Creators: name: Julian, Carla M.

Year: 2003

description: The number of persons age 65 and older is increasing rapidly in many areas of the world. By the year 2030, one in five Americans will be age 65 or older. As the population ages, more people require long term care services in nursing homes and assisted living facilities. This paper reviews key issues in nursing home and assisted living care, but the main focus is the assisted living industry. A brief overview of nursing home characteristics is followed by a more in-depth analysis of the assisted living industry, including a review of North Carolina assisted living legislation. The main topics discussed include: • long-term care terminology; • resident assessment standards; • caregiving workforce; • staffmg affect on quality; • resident characteristics; • resident values and preferences; • licensure and certification; • availability of meaningful • quality measurement; activities. • staffing requirements; Assisted living is a promising option for older adults who can no longer live independently at home, but there are concerns surrounding staff training, qualifications, and supervision; medication administration; resident assessment protocols; and the availability of meaningful activities. Minimal research is available documenting the structure and process of care relative to medication administration errors. Professional nursing oversight has been recommended as a possible intervention to reduce medication error rates, but without supporting evidence documenting the processes contributing to these errors, recommending such legislation is premature. There are also no available studies documenting the proportion of assisted living residents whose conditions deteriorate after admission, how personal care staff react to changes, assessment tools and interventions used by professional nurses in response to changes, or whether interventions affect outcomes. Observational studies are needed in this area so advocates and care providers can lobby for appropriate legislation. Another critical component to quality of life for assisted living residents is the availability of meaningful activities that are individualized and sufficient to relieve loneliness, boredom, and depression. It is possible that current state legislation requiring resident assessment documentation could be amended to include documented evidence of adequate assessment and planning to meet resident activity needs. One thing is certain, as the older adult population continues to rise over the next 30 years; the assisted living industry will see a corresponding rise in the number of frail, functionally impaired residents. Policies and regulation particular to assisted living will need to change along with these changing demographics.

description: The focus of the present study is on the vibroacoustic loads that form during the startup of TOP contoured rocket nozzles. A urethane-based compliant walled nozzle is employed to investigate the effects of fluidstructure interactions on supersonic jet noise emission. Measurements of the nozzle-wall deformation, by means of tracking tracers on the nozzle lip, are synchronised with pressure-field microphones located in the near vicinity of the nozzle jet plume. Results are compared with those obtained from a baseline rigid wall nozzle fabricated from aluminium. Findings reveal that the inclusion of aeroelasticity in the experimental framework of sub-scale nozzle flow testing reduces the acoustic intensity over a large range of nozzle pressure ratios. Particularly, the aeroelasticity is responsible for the suppression of broadband shock noise and a strong tonal coupling just prior to FSS to RSS transition.

description: Recently Feferman (Rev. Symb. Logic 6: 6-15, 2013) has outlined a program for the development of a foundation for naive category theory. While Ernst (ibid. 8: 306-327, 2015) has shown that the resulting axiomatic system is still inconsistent, the purpose of this note is to show that nevertheless some foundation has to be developed before naive category theory can replace axiomatic set theory as a foundational theory for mathematics. It is argued that in naive category theory currently a 'cookbook recipe' is used for constructing categories, and it is explicitly shown with a formalized argument that this 'foundationless' naive category theory therefore contains a paradox similar to the Russell paradox of naive set theory.

What's the Difference? Measures of Racial Disparity in Rates of a Sexually Transmitted Disease

Year: 2002

description: Background: Elimination of racial disparities in health is a national health priority, yet little attention has been devoted to the choice of measures used to quantify disparity. Community-level risk factors for racial disparity in STDs are largely unstudied. Goal: To determine whether ten county-level demographic variables were associated with black-white disparity in gonorrhea incidence rates in North Carolina and to investigate how the association between the variables and racial disparity varied depending upon the measure of disparity used [incidence rate ratio (RR) vs. incidence rate difference (RD)]. Methods: We examined the relationships between the demographic variables and 5-year county average black-white RR and RD in gonorrhea in NC using simple linear regression, scatter plots, and Pearson's correlations. Results: All variables except sex ratio were more strongly correlated with RD than with RR. RD was strongly positively correlated with the incidence rate of gonorrhea among blacks (>0.99) and RR was less so (0.30). Conclusions: Several county-level variables are associated with additive racial disparity in gonorrhea in NC. This is likely due to the fact that RD is highly correlated with gonorrhea rates in the black population, and correlation of the variables with RD essentially reflects correlation with gonorrhea rates in the black population. Public health interventions aimed at reducing racial disparity in gonorrhea in NC should primarily aim to reduce absolute disparities.

description: We prove that the log-determinant of the covariance matrix obeys the strong subadditivity inequality for arbitrary tripartite states of multimode continuous variable quantum systems. This establishes general limitations on the distribution of information encoded in the second moments of canonically conjugate operators. The inequality is shown to be stronger than the conventional strong subadditivity inequality for von Neumann entropy in a class of pure tripartite Gaussian states. We finally show that such an inequality implies a strict monogamy-type constraint for joint Einstein-Podolsky-Rosen steerability of single modes by Gaussian measurements performed on multiple groups of modes.

description: This paper investigates a new Hw interval filter design methodology and presents an innovative application of the filter developed to estimate satellite true attitude state for navigation units in space missions. The key element of the proposed approach is to use an interval filter structure advantage, rather than an observer-based structure (relying only on a system dynamics structure). Indeed, the interval filter design is an emerging research field, the design problem is formulated as an arbitrary order generic state-space realization. Thus, such state-space realization offers more degrees of freedom in its design, since it relies on a synthesis which is solved on an order which can be inferior, superior or equal to the system state space order, improving the interval state estimation performance, in a H00 -gain criterion sense. The H00 theory is used to enhance robustness against sensor misalignment errors, noises unknown inputs and disturbances for satellite missions application.

description: We study the loading of a nonequilibrium, dissipative system of composite bosons -- exciton polaritons -- into a one dimensional periodic lattice potential. Utilizing momentum resolved photoluminescence spectroscopy, we observe a transition between an incoherent Bose gas and a polariton condensate, which undergoes further transitions between different energy states in the band-gap spectrum of the periodic potential with increasing pumping power. We demonstrate controlled loading into distinct energy bands by modifying the size and shape of the excitation beam. The observed effects are comprehensively described in the framework of a nonequilibrium model of polariton condensation. In particular, we implement a stochastic treatment of quantum and thermal fluctuations in the system and confirm that polariton-phonon scattering is a key energy relaxation mechanism enabling transitions from the highly nonequilibrium polariton condensate in the gap to the ground band condensation for large pump powers.
Successful Aging: Using Information Technology to Enhance the Lives of Older Adults

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: According to the 2007 State of Aging report from the US Centers of Disease Control and Prevention (CDC), the population growth of older adults today is unprecedented in American history. Experts agree that the growth is due in part to medical advances that have dramatically changed the landscape of aging in America. Today, chronic diseases have replaced infectious diseases and acute illness as the leading causes of death. In fact, some 80 percent of older adults are believed to have at least one chronic or degenerative disease. The report cites two forces- a longer lifespan and the maturing of the 77 million babyboomers- that will result in the doubling of the population of Americans 65 years and older by 2030. This dramatic change is also expected to raise existing healthcare costs by 25 percent. These factors are bringing attention to the capabilities of aging services in America. The impetus is strong to mitigate factors contributing to age-related, debilitating diseases such as heart disease, diabetes and cancer and in tum to achieve a better quality of life through healthier aging options. Community-based intervention models have achieved some success in addressing these concerns. But, as the aging population continues to grow, opportunities are emerging to integrate information technology in the approach to maximize the ability to age successfully, including opportunities to promote independence and quality of life.

description: We report theoretical calculations and experimental observations of Pancharatnam's phase originating from arbitrary SU(2) transformations applied to polarization states of light. We have implemented polarimetric and interferometric methods which allow us to cover the full Poincaré sphere. As a distinctive feature, our interferometric array is robust against mechanical and thermal disturbances, showing that the polarimetric method is not inherently superior to the interferometric one, as previously assumed. Our strategy effectively amounts to feed an interferometer with two copropagating beams that are orthogonally polarized with respect to each other. It can be applied to different types of standard arrays, like a Michelson, a Sagnac, or a Mach-Zehnder interferometer. We exhibit the versatility of our arrangement by performing measurements of Pancharatnam's phases and fringe visibilities that closely fit the theoretical predictions. Our approach can be easily extended to deal with mixed states and to study decoherence effects.

description: Background: Black females in the United States face unique sociocultural conditions that impact their sexual development and increase their risk for sexually transmitted infections (STI), including but not limited to chlamydia, gonorrhea, and HIV. Research has not adequately explained how sociocultural conditions contribute to this increased risk. The purpose of our investigation was to explore the sociocultural conditions that influence Black cisgender females risk for STI. Methods: This grounded theory study involved in-depth audio-recorded interviews with 20, primarily heterosexual, Black females ages 19–62. Results: Findings informed a conceptual model that builds on previous theory about the sexual development of Black females and explains how sociocultural conditions impact two, participant identified, sexual pathways: Fast and Cautious. Movement on these sexual pathways was not always a linear trajectory; some participants shifted between pathways as their sociocultural contexts changed (i.e., sexual assault, STI, and level of protection). The Fast sexual pathway often led to greater STI risk. Conclusions: This model may inform future research designed to prevent STI/HIV and promote the sexual health of Black females across the life course.

description: A liquid propulsion system is one of the key systems to space transportation. In addition, autonomous decision-making, without earth-based control or astronauts, will become important for space exploration of the lunar orbit and beyond. One solution for quick and accurate fault diagnosis of fluidic components is to focus on the dynamic pressure response in the piping system. This solution is realized by modelbased approach to obtain a prior dataset under fault conditions. This paper covers the results of consideration and preliminary analysis to develop a demonstration plan on orbit utilizing the HTV-X as an experimental platform for future technologies.
Publicly Funded Mental Health Services in Durham County, North Carolina: An Analysis of the System, Who it Serves, and Recommendations for Improved Access for Adults Suffering from Severe and Persistent Mental Illness
Creators: name: Ohlsson-Shepherd, Jonathan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: State-funded mental health support for adults living within Severe and Persistent Mental Illness (SPMI) is chronically underfunded and unaccountable to the patients that it serves. Like in many parts of the country, the true costs of these gaps in coverage fall on other social systems such as emergency medicine and the justice system, failing to efficiently spend tax payer money. There are a number of steps that can be taken, specific to Durham County, in order to reconcile these shortcomings and best provide financially and socially responsible services to adults with SPMI. Most significant, State and Federal budgets should be committed in a way that allows for long-term planning on the part of service providers. It is also recommended to increase the allocations of funds that support long-term care, as well as research that supports transparency in outcomes and early diagnostics and intervention. Additionally, social programs that raise awareness of mental illness to reduce stigma, educate the public on treatment options, and help support the affected community, should be expanded upon to ensure that adults with SPMI in Durham are supported in the same manner as other health conditions.

description: We study a two filament driven lattice gas model with oppositely directed species of particles moving on two parallel filaments with filament switching processes and particle inflow and outflow at filament ends. The filament switching process is {\it correlated} such that particles switch filaments with finite probability only when oppositely directed particles meet on the same filament. This model mimics some of the coarse grained features observed in context of microtubule (MT) based intracellular transport, wherein cellular cargo loaded and off-loaded at filament ends are transported on multiple parallel microtubule (MT) filaments and can switch between the parallel microtubule filaments. We focus on a regime where the filaments are weakly coupled, such that filament switching rates scale inversely as the length of the filament. We find that the interplay (off)loading processes at the boundaries and the filament switching process leads to some distinctive features of the system. These features includes occurrence of variety of phases in the system with inhomogeneous density profiles including localized density shocks, density difference across the filaments and bidirectional current flows in the system. We analyze the system by developing a mean field (MF) theory and comparing the results obtained from the MF theory with the Monte Carlo (MC) simulations of the dynamics of the system. We find that the steady state density and current profiles of particles and the phase diagram obtained within the MF picture matches quite well with MC simulation results. These findings maybe useful for studying multi-filament intracellular transport.

Publisher: name: London South Bank University
Year: 2020

description: Forensic Radiography has seen a rapid development over the last 20 years with the evolution of new technologies, but perhaps more significantly development of policy and guidelines for radiographers, the adoption of standards and standard operating procedures and changes in education and training. This thesis explores the author’s contribution to the body of knowledge in this discipline through the use of participatory action research which was undertaken through a sequence of iterative cycles over time. The author, as practitioner-researcher, examined the practice of forensic radiography through these cycles of data gathering, studying a number of different operational situations, each of which presented specific organisational issues requiring resolution. Practitioners and service users as members of the organisational system were active participants in the cyclical process of planning, taking action and evaluating the actions. Longitudinal, cross sectional and case study research designs employed observation and reflection, focus groups and multidisciplinary group discussions, questionnaires and semi-structured interviews. These led to collaborative findings and the development of new knowledge that was applied to subsequent situations, which were then further examined and refined within an overarching action research model. The thesis highlights the author’s new contributions to the body of knowledge from the respective studies and resultant publications with specific reference to the development of standards, protocols and standard operating procedures in forensic radiography.

description: The development of space logistics is not solely dependent on technology, it requires interdisciplinary collaboration. Meanwhile, terrestrial logistics have undergone a significant transformation, shifting from subcontracting to Omni-channel approach among which LLP model is recognized as a model that integrates multiple capabilities to continuously improve the operations. Given that the success of the emerging space economy hinges on a self-sustaining ecosystem, this research aimed to analyse the satellite supply chain for application of LLP. Currently, there are barriers impacting application of LLP in the satellite supply chain; however, there is a noteworthy development in the form ofMicroLLP, employed for microsatellites.

description: We study the evolution of the rotation rate of a proto-neutron star, born in a core-collapse supernova, in the first seconds of its life. During this phase, the star evolution can be described as a sequence of stationary configurations, which we determine by solving the neutrino transport and the stellar structure equations in general relativity. We include in our model the angular momentum loss due to neutrino emission. We find that the requirement of a rotation rate not exceeding the mass-shedding limit at the beginning of the evolution implies a strict bound on the rotation rate at later times. Moreover, assuming that the proto-neutron star is born with a finite ellipticity, we determine the emitted gravitational wave signal, and estimate its detectability by present and future ground-based interferometric detectors.

REGRESSION RATE

description: Paraffin-based fuels are considered promising propellants for hybrid rockets due to their fast-burning rates. These fuels produce a thin liquid layer on the surface of the solid fuel, which promotes the entrainment of droplets and consequently enhances regression rates. In this study, we introduce a new mechanism for mass transfer and investigate the regression rate resulting from the presence of a liquid film on the solid fuel surface. To achieve this, we utilized a two-dimensional slab hybrid motor and three different types of paraffin-based fuel with varying viscosity of the liquid film. The results demonstrated that mass transfer caused by the liquid film played a significant role, making a substantial contribution to the overall regression rate.

description: In order to deepen in the knowledge of the vibrational properties of 2-dimensional MoS2 atomic layers, a complete and systematic Raman scattering analysis has been performed using both bulk single crystal MoS2 samples and atomically thin MoS2 layers. Raman spectra have been measured under non-resonant and resonant conditions using seven different excitation wavelengths from near-infrared (NIR) to ultraviolet (UV). These measurements have allowed to observe and identify 41 peaks, among which 22 have not been previously experimentally observed for this compound, characterizing the existence of different resonant excitation conditions for the different excitation wavelengths. This has also included the first analysis of resonant Raman spectra that are achieved using UV excitation conditions. In addition, the analysis of atomically thin MoS2 layers has corroborated the higher potential of UV resonant Raman scattering measurements for the non destructive assessment of 2 dimensional MoS2 samples. Analysis of the relative integral intensity of the additional first and second order peaks measured under UV resonant excitation conditions is proposed for the non destructive characterization of the thickness of the layers, complementing previous studies based on the changes of the peak frequencies.

description: To assess the location of transition on generic flight vehicles, a tool has been developed [5] which applies existing correlations to complex CFD solutions. This paper presents two improvements to this tool. First of all, a new interpolation algorithm which allows to evaluate the transition evolution of complex vehicles along their flight paths. Secondly, we present an improved methodology for the first estimation of the boundary layer thickness. A first validation case, based on experimental data found in literature, shows good agreement to the current methodology. Finally, a geometric analysis on a launcher fairing is presented as a first application and shows the strength of the tool.

description: The most energetic neutron stars, powered by their rotation, are capable of producing pulsed radiation from the radio up to gamma rays with nearly TeV energies. These pulsars are part of the universe of energetic and powerful particle accelerators, using their uniquely fast rotation and formidable magnetic fields to accelerate particles to ultra-relativistic speed. The extreme properties of these stars provide an excellent testing ground, beyond Earth experience, for nuclear, gravitational, and quantum-electrodynamical physics. A wealth of gamma-ray pulsars has recently been discovered with the Fermi Gamma-Ray Space Telescope. The energetic gamma rays enable us to probe the magnetospheres of neutron stars and particle acceleration in this exotic environment. We review the latest developments in this field, beginning with a brief overview of the properties and mysteries of rotation-powered pulsars, and then discussing gamma-ray observations and magnetospheric models in more detail.

Teen Pregnancy: Addressing the Problem of Teen Pregnancy among Latinos

description: The United States continues to have the highest rates of teen pregnancy when compared to other nations despite declining rates over the last few years. The Latina population is disproportional affected by these higher rates. Latinas had the highest teen birth rate of all major ethnic groups in the United States with 83 births per 1,000 teens aged 15-19 in 2004 alone, a rate nearly double of the national rate at 41.1 In addition, the Latino population is the fastest growing ethnic group in the United States. Economic and cultural barriers have limited access to health care and teen pregnancy prevention and education programs for this population. The number of young Latina mothers and children who are poverty stricken or lack health care are like! y to see an increase as the teen birth rate increases. Moreover, there are several reasons that indicate why some Latina teens may want to become pregnant. Sex education is needed to lower teen pregnancy in this population but also to address some of the cultural, social and economic problems that may afflict this community. There are effective and promising programs that help tackle this issue, but there is more work to be done in public policy to continue these efforts. This paper takes a closer look at some of the issues surrounding teen pregnancy among Latinos and provides an overview of policy and programs.

description: In a recent paper (arXiv:1412.6000) a general mechanism for emergence of cosmological space-time geometry from a quantum gravity setting was devised and departure from standard dispersion relations for elementary particle were predicted. We elaborate here on this approach extending the results obtained in that paper and showing that generically such a framework will not lead to higher order modified dispersion relations in the matter sector. Furthermore, we shall discuss possible phenomenological constraints to this scenarios showing that space-time will have to be by nowadays classical to a very high degree in order to be consistent with current observations.
