description: Points-of-care (PoCs) augment healthcare systems by performing care whenever needed and are becoming increasingly crucial for the well-being of the worldwide population. Personalized medicine, chronic illness management, and cost reduction can be achieved thanks to the widespread adoption of PoCs. Significant incentives for PoCs deployment are nowadays given by wearable devices and, in particular, by RFID (RadioFrequency IDentification) and NFC (Near Field Communications), which are rising among the technological cornerstones of the healthcare internet of things (H-IoT). To fully exploit recent technological advancements, this paper proposes a system architecture for RFID- and NFC-based PoCs. The architecture comprises in a unitary framework both interfaces to benefit from their complementary features, and gathered data are shared with medical experts through secure and user-friendly interfaces that implement the Fast Health Interoperability Resource (FHIR) emerging healthcare standard. The selection of the optimal UHF and NFC components is discussed concerning the employable sensing techniques. The secure transmission of sensitive medical data is addressed by developing a user-friendly "PoC App" that is the first web app exploiting attribute-based encryption (ABE). An application example of the system for monitoring the pH and cortisol levels in sweat is implemented and preliminarily tested by a healthy volunteer.

description: Magnetic measurement errors significantly affect the wellbore positional accuracy in directional drilling operations taken by Measurement While Drilling (MWD) sensors. Therefore this research has provided a general overview of error compensation models for magnetic surveys and elaborated the most accurate calibration methods of hard- and soft-iron, as well as multiple-survey correction for compensating drilling assembly magnetic interference to solve the problem of wellbore positional uncertainty and provide accurate surveying solution downhole. The robustness of hard- and soft-iron calibration algorithm was validated through an iterative least-squares estimator initialized using a two-step linear solution. A case study of a well profile, a simulated well profile and a set of experimental data are utilized to perform a comparison study. The comparison analysis outcomes imply that position accuracy gained by multistation analysis surpasses hard- and soft-iron compensation results. Utilization of multiple-survey correction in conjunction with real-time geomagnetic referencing to monitor geomagnetic disturbances, such as diurnal effects, as well as changes in the local field by providing updated components of reference geomagnetic field, provide superior accuracy.

description: Turbot is a valuable commercial fish species classified as endangered. Knowledge of the level and distribution of genetic diversity in turbot is important for designing conservation strategies for their sustainable survival and to preserve their evolutionary potential. Mitochondrial control region sequences were investigated to evaluate variability in population genetic structure of one population along the northern Black Sea coast. 19 CR haplotypes were found in the Shabla population, which were shared with turbot haplotypes, previously described for the Black Sea and the Mediterranean. A pattern with a high level of haplotype diversity (h = 0.954 ± 0.022) and a very low level of nucleotide diversity (π = 0.00563 ± 0.00063) indicated a high number of closely related haplotypes and suggested that this population may have undergone a recent expansion. Tajima’s D test and Fu’s FS test both suggest recent population growth. The haplotypes found in the Shablа population were typical for the north Black Sea populations and could be used for distinguishing the population along the Bulgarian Black Sea coast.

description: The purpose of this study was to determine the effects of 0.12% chlorhexidine rinse (CID{) and herbal rinse (HBR) to placebo, on gingival health status over time. Methods: 63 subjects (57% male, 43% female, mean age 25 years, sd=7.67) were randomly assigned to one of three treatment groups; CHX, HBR, or placebo. Subjects rinsed twice daily (AM and PM) with ½ ounce of allocated rinse, after brushing and flossing, for three months. Subjects were given the same type of soft bristle toothbrush and whitening toothpaste. Participants were advised to refrain from use of any other oral rinse for the duration of the study. No other attempt was made to modify subject daily oral care. Data were collected at baseline, month 1, 2, and 3, using the Gingival Index (GI), the Plaque Index (Pl), and bleeding on probing (BOP). A full mouth periodontal probing (six sites per tooth) was obtained at baseline and at the completion of the study. A soft tissue assessment was completed at each visit. Data were analyzed using generalized linear models. CHX was the only oral rinse to demonstrate a statistically significant effect on the reduction of GI scores of 2 or 3 (p= 0.012) and on the reduction of BOP (p= 0.005) when compared to placebo over time. The effects of HBR on bleeding was not statistically greater than placebo (p= 0.995) from baseline to month 3. CHX demonstrated a 29% reduction in the proportion of subjects with a GI score of either 2 or 3 (x= -0.290, sd= 0.144) and a 29% reduction in the proportion of positive BOP sites xi= -0.291, sd= 0.144) between baseline and month 3. A comparable 29% reduction in GI and BOP scores with CHX is expected since bleeding is reflected in GI scores. The effects of HBR on reducing GI scores of 2 or 3, or BOP were not statistically greater than placebo between baseline and month 3 (p= 0.882). There was no statistically significant difference from baseline to month 3 in PI scores among CHX and HBR when compared to placebo (p= 0.098, p= 0.505 respectively).

description: With increased longevity and as younger, more physically active patients are receiving joint replacements, it has become increasingly important to measure the failure rate for joint replacements using the cumulative incidence of revision. The most commonly applied survival analysis technique, the Kaplan-Meier (KM) method, does not account for competing risks (i.e., patient deaths) and consequently overestimates the cumulative incidence. This thesis examines alternative methods for estimating the cumulative incidence of revision using population-based cohorts of hip and knee replacements performed in Alberta and Sweden. In comparing the KM method to the cumulative incidence function, which accounts for competing risks, the KM method overestimated the cumulative incidence at each time point. The magnitude of overestimation increased with follow-up time and higher mortality rates. Application of three regression models demonstrated competing risks models require careful interpretation. Competing risks methods are recommended to accurately estimate revision rates for healthcare planning purposes.

description: Gamma-ray bursts categorically produce broadband afterglow emission, but in some cases, emission in the optical band is dimmer than expected based on the contemporaneously observed X-ray flux. This phenomenon, aptly dubbed "optical darkness", has been studied extensively in long GRBs (associated with the explosive deaths of massive stars), with possible explanations ranging from host environment extinction to high redshift to possibly unique emission mechanisms. However, investigations into optical darkness in short GRBs (associated with the mergers of compact object binaries) have thus far been limited. This work implements a procedure for determining the darkness of GRBs based on spectral indices calculated using temporally-matched Swift-XRT data and optical follow-up observations; presents a complete and up-to-date catalog of known short GRBs that exhibit optical darkness; and outlines some of the possible explanations for optically dark short GRBs. In the process of this analysis, we developed versatile and scalable data processing code that facilitates reproducibility and reuse of our pipeline. These analysis tools and resulting complete sample of dark short GRBs enable a systematic statistical study of the phenomenon and its origins, and reveal that optical darkness is indeed quite rare in short GRBs, and highly dependent on observing response time and observational effects.

description: Canada’s French Immersion program, introduced in the mid-1960s, is widely recognized as a successful classroom model for developing language competence. The accuracy of the written production of French Immersion students has been problematic (Genesee 1987; Harley 1989; Cummins 2000; Lyster 2007; Burger et al 2011) and is a particular challenge for those students in high school who intend to use French for post-secondary education or to seek employment opportunities. In this study, R. Lyster’s 2007 Noticing-Awareness-Practice model is used for the delivery of explicit grammar instruction about the direct and indirect object pronouns in a Grade 12 French Immersion language class. The cognitive maturity of Grade 12 students and their implicitly-built knowledge and understanding of French could provide an advantage in the learning context provided by the model. Following L.S. Vygotsky’s (1978) view of the value of peer work in the classroom, peer collaboration is included in the model in order to encourage metatalk and languaging, identified by M. Swain (2001; 2010) as a way to encourage students to reflect on language use and to enhance their metalinguistic awareness. The goal of the study was to explore the effects of explicit instruction about the targeted structure on students’ written production and the effects of such instruction on their metalinguistic awareness. Following a mixed method study design, quantitative data were collected from a treatment class and a control class at three times, and supporting qualitative data were provided by student and teacher interviews and audio recordings of peer work groups in the treatment class. The results from this study show that providing explicit and proactive grammar instruction within the framework of Lyster’s model, supplemented by opportunities for peer interaction, can enhance students’ metalinguistic awareness, and have a positive impact on the accuracy and frequency of use of the targeted structure in their written production. These results support the creation of curriculum materials that will assist French Immersion teachers in implementing such a model in their classroom in order to improve the accuracy of students’ written production and to enhance their metalinguistic awareness; a sample document inspired by the study is included.

description: We present a truncation scheme of the effective average action approach of the nonperturbative renormalization group which allows for an accurate description of the critical regime as well as of correlation functions at finite momenta. The truncation is a natural modification of the standard derivative expansion which includes both all local correlations and two-point and four-point irreducible correlations to all orders in the derivatives. We discuss schemes for both the symmetric and the symmetry broken phase of the O(N) model and present results for D=3. All approximations are done directly in the effective average action rather than in the flow equations of irreducible vertices. The approach is numerically relatively easy to implement and yields good results for all N both for the critical exponents as well as for the momentum dependence of the two-point function.

description: The activated sludge process is a nonlinear, time-varying, multi-input-multi-output system. It is important to design an adaptive control strategy, which can not only track the setpoint changes quickly, but also adapt to the system uncertainties and disturbance signals. The current work presents a single-input-single-output Generalized Predictive Controller to regulate the dissolved oxygen concentration and a multi-loop Generalized Predictive Control scheme to control the dissolved oxygen concentration and the substrate concentration. The control is tested with both a simplified four-state model and an activated sludge model no. 1 (ASM1) benchmark of an activated sludge process. In the univariate algorithm, the manipulated variable (controller output) is the air flow rate (or the oxygen transfer coefficient) and the controlled variable (measured variable) is the dissolved oxygen concentration. On the other hand, for the multivariable process, two separate control loops are taken into consideration such that in the first control loop, the air flow rate (or the oxygen transfer coefficient) is used to regulate the dissolved oxygen concentration, and in the second control loop, the recycled to influent rate (or the return sludge flow rate) is used to manipulate the substrate concentration. Initially, the GPC controller is implemented in the presence of white measurement noise. In this case, an ARX model is used as the prediction model in a GPC structure. The RLS identification method estimates the parameters of this ARX model. Then, the ability of GPC controller in the presence of random walk disturbance (coloured noise together with an integral factor) is tested. In this case, a CARIMA model is used as the prediction model and an ELS identification method is used to estimate the parameters of this model. A method which can compensate the effect of coloured noise is GPC with T filter. The results of a conventional GPC controller is compared with a GPC with T filter and a PI controller.

description: Success...how can we define and achieve a recognizable, compelling and admirable success? Many studies done by different researchers indicated that there is no definite general agreement on the definition of success or the contributing factors. On the other hand, there is not much disagreement on the definition of failure. A persistent high rate of projects that were unsuccessful in meeting their targets has haunted many industries and organizations, posing the research main question: Why do many projects fail to meet targets of budget, schedule, quality or performance in spite of the fact that management methods and techniques are widely available, applied science and technologies are rapidly improving and advancing? Research has shown that a large number of projects were managed mainly as technical systems rather than behavioural system, with relatively little attention being paid to the human factor. Literature examining soft aspect management is scarce; however, a new trend in research began to recognize the critical importance of the human factor, thus, the first part of the eight chapters in the body of this thesis is dedicated to developing in-depth understanding of the human factor effect and identifying relevant and critical strategic success factors. The area of focus is the front-end planning, in particular, the strategic pre-planning stage. The second main part in this thesis presents a modern management model including significant numerical weighting values. This model was structured based on literature findings, relevant knowledge obtained from social, culture, psychological and behavioural sciences, results and analyses of an undertaken survey and interviews for the purpose of this research. The triangulation approach as the strategy of choice is well suited for the thesis objectives and offers great benefits through the application of multi-methods, including qualitative (grounded theory) and quantitative analysis. Data collection, analyses and validation progressed consistently aided by multiple rounds of Delphi technique. Thesis deliverables included a new practical definition for success and a novel management model featuring a systematic evolutionary methodology designed to modernize management philosophy, generate optimum strategic management decisions and increase the probability of success and achievement.

description: The question whether a Riemannian manifold is geodesically connected can be studied from geometrical as well as variational methods, and accurate results can be obtained by using the associated distance and related properties of the positive-definiteness. It is natural to state this problem in manifolds with (possibly non-smooth) boundary, and some conditions on this boundary has been studied. For Lorentzian manifolds, the results cannot be so general, and very different techniques has been introduced which are satisfactory for some classes of Lorentzian manifolds: spaceforms, disprisoning and pseudoconvex manifolds, stationary, globally hyperbolic or multiwarped spacetimes... Some of them are appliable to semi-Riemannian manifolds with higher index or even to manifolds with just an affine connection. Our purpose is to review these semi-Riemannian techniques, discussing the results and possible extensions.

description: The aim of this research study was to generate knowledge about how registered nurses experience the moral dimensions of their practice. Narrative inquiry was used to explore the lived and told stories of how nurses navigate moral tensions and conflicts in order to continue practicing within the profession. It is important to understand how nurses adapt, cope, and gain resilience because complex healthcare situations sometimes have outcomes that are morally unacceptable to nurses, leaving them distressed and causing them to leave the places in which they practice, or leave the profession altogether. This study is a narrative inquiry, using the approach advocated by Connelly and Clandinin (1990) and Clandinin and Connelly (2000). Proceeding from the position that people compose themselves through stories, lived and told, this research examined the stories of five registered nurses practicing in public health. Participants in this study shared their accounts of overcoming moral conflicts in practice. By attending to Clandinin and Connelly’s (2000) metaphorical three-dimensional narrative inquiry space, the subtleties of particular places, the social contexts of nurses’ relationships with others, and the temporally situated aspects of ethics in practice were revealed. This research concludes with recommendations for workplace changes, education, and ongoing professional development for nurses to transition across ethical practice situations while fostering their professional integrity.

description: For development of reusable biosensor chips, bioreactors, protein arrays, and matrices for affinity purification of proteins, it would be ideal for streptavidin to have extremely tight binding to its target ligands (biotin and its binding tags) and at the same time to retain the feature of reversible binding capability. To achieve this objective, a streptavidin mutein (SAVSBPM32) was engineered based on a previously engineered streptavidin variant (SAVSBPM18) that can bind both biotin and its binding tag in a reversible manner. Cysteine residues were placed in strategic positions in both the streptavidin mutein and its binding tags. Disulfide bond formation allows immobilization of tagged proteins to streptavidin. Incubation with biotin in the presence of reducing agents allows stripping off tagged proteins from streptavidin.

We show here that all these features result from electronic correlations and are quantitatively reproduced by calculations combining density-functional theory and dynamical mean-field theory. The importance and general relevance of correlation effects in filled bands coupled by inter-orbital interactions to a partially-filled band are pointed out.

Third-generation synchrotron x-ray sources are advantageous for x-ray phase contrast imaging (PCI) and diffraction under dynamic loading, due to their high photon energy, high photon fluxes, high coherency, and high pulse repetition rates. The feasibility of bulk-scale gas gun shock experiments with dynamic x-ray PCI and diffraction measurements was investigated at the beamline 32ID-B of the Advanced Photon Source. The x-ray beam characteristics, experimental setup, x-ray diagnostics, and static and dynamic test results are described.

Economic analysis of blueberry investment in British Columbia
Creators: name: Yang, Jinbin
Publisher: name: University of British Columbia
Year: 2010

description: The objective of this thesis is to examine reasons for boom-and-bust cycles of blueberries in British Columbia as a case study by performing financial analysis, estimating a price elasticity of blueberry supply, and simulating changes in the price and acreage of blueberries. In order to achieve the above stated objectives, three models will be constructed. First, a business planning spreadsheet model is constructed in order to analyze the profitability of blueberry investment in British Columbia. The model studies the profitability of blueberry production with high prices during the boom period and low prices during the bust period. The results demonstrate that farmers make fairly good returns on investment during times of high prices in the blueberry boom, while the returns in the bust period can barely cover their production costs. Second, the dynamic supply response model of Nerlove (1958) is adopted in order to estimate a reduced form supply function for blueberry producers in British Columbia. The results show that blueberry farmers had an inelastic response to price changes in the short run and a highly elastic response to price changes in the long run. These findings help to explain why the acreage of blueberries has rapidly expanded over the past decade. Third, on the basis of the estimated price elasticities of blueberry supply, the cobweb model is used in order to simulate boom-and-bust cycles in the price and acreage of blueberries. The simulation adopts the convergent type of cobweb because the demand elasticity of blueberries is expected to be elastic. The result of simulations indicates that the more elastic the demand curve is, the quicker the price and acreage of blueberries converge to a steady state.

description: The generation of toxic tailings water from the Athabasca Oil Sands via hot water extraction processes poses a serious threat to the future sustainability of the region. Liquid tailings are stored in settling ponds on company leases where they continue to accumulate. The absence of an economically feasible method to treat this waste water and unclear environmental guidelines regarding remediation of this waste water has resulted in enormous ponds contaminated with napththenic acids (NAs) and other petroleum organics. An effective solution for sufficient remediation of the tailings ponds and oil sands process-affected water (OSPW) prior to mine closure is critical. To address this issue, we have initiated a study to explore the potential for algal-based bioremediation strategies. We have identified the species Dunaliella tertiolecta as being capable of degrading model NAs as well as a fraction of classical NAs found in OSPW. Furthermore, we have demonstrated enhanced in situ detoxification of OSPW through the biostimulation of indigenous photosynthetic organisms by phosphate supplementation. Detoxification appears to be linked with the reduction of sulfonate compounds which suggest toxicity is not predominantly caused by NAs as was previously believed. In addition to algal remediation studies, we developed the yeast Schizosaccharomyces pombe as a toxicological indicator for OSPW toxicity. Chemical genetic screens corroborate sulfonate toxicity in OSPW and transcriptomic investigations generated hypotheses regarding the mode of OSPW toxicity at the cellular level. Transcriptomic studies suggested that OSPW contaminants affect the integrity of biological membranes and incur oxidative stress. Because the mode of OSPW toxicity is poorly understood, we believe these studies contribute to the need for a comprehensive understanding of OSPW toxicity for site monitoring and remediation purposes.
Reservoir-Wave Analysis Applied to the Pulmonary Circulation

description: The purpose of applying the reservoir-wave model to the pulmonary circulation is to validate the resulting reservoir and wave parameters against known physiologic responses. The reservoir model represents a modified windkessel and describes the lumped resistance to flow, compliance of vessels and the downstream pressure at which modeled outflow ceases. Applied to arteries and veins in tandem, a complete description of the pulmonary circulation is possible. The reservoir model determines the reservoir pressure, which is subtracted from measured pressure. The difference is called excess pressure and it is used with wave intensity analysis to quantify the effects of incident waves and their reflections. The changes to reservoir function and wave patterns may be helpful in providing extra diagnostic information regarding pulmonary hypertension and providing targets for treatment of this disease. Measurements of pressure and flow were made in the main pulmonary artery and pulmonary vein in 15 anesthetised, open-chest dogs. Six different conditions were created by the addition of blood volume and the application of positive end-expiratory pressure (PEEP). At each condition, hypoxic ventilation was used to create vasoconstriction and then, inhaled nitric oxide was used to create vasodilation. Ventilation changes are the focus of experimentation because hypoxia represents a pulmonary hypertension disease state and nitric oxide represents a common treatment. Both arterial and venous reservoir resistance increased with hypoxia and decreased with nitric oxide but only arterial reservoir resistance was fully reversed with nitric oxide. With excess pressure, arterial wave patterns revealed the presence of a prominent negative reflection occurring from the junction of arteries branching from the left or right pulmonary artery. Venous wave patterns showed that the left atrium and ventricle are responsible for the majority of measured pressure fluctuations but a wave transmitted from the pulmonary arteries is measurable during the filling of the left atrium. Overall, results are in general agreement with hypothesized physiological changes, which serves to validate the application of the reservoir-wave model and allows both the vascular characteristics and wave propagation to be quantified in ways that other models can not.

description: Expanding on theoretical work by Heinze et al.1, an optical setup to experimentally realize three-colour fluorescence cross-correlation spectroscopy (3C-FCCS) was designed. This instrument simultaneously collects and correlates fluorescence data from three colour channels, allowing real-time tracking of three-coloured species in complex solutions. To examine 3C-FCCS theory, a nanobarcode test particle, which physically linked three fluorophores was selected and characterized. These nanobarcode particles, capable of producing a triple cross-correlation decay, facilitated proof-of-concept experiments. 3C-FCCS was shown to be capable of measuring the concentration of nanobarcode particles in solution exclusively containing nanobarcode particles and solution containing nanobarcodes outnumbered by background quantum dots at a ratio of 800:1. 3C-FCCS was used to investigate a simple DNA-based nanostructure. These experiments illustrate that 3C-FCCS is a compelling technique with a plethora of potential applications, ranging from investigating hierarchical nanoassembly to biological reactions.

description: Utilising feed processing technologies to alter the physical and chemical composition of feed materials and enhance nutrient quality, stability, and hygiene is one strategy the feed industry is looking for to offset rising raw material costs. In the last few decades, feed processing has progressed from straightforward "grind and mix" to more sophisticated thermal procedures that combine mechanical and thermal processing of feed ingredients, like pelleting, expanding, and extrusion. Feed processing alters the feed ingredients' molecular structures and particle sizes, among other physical and chemical changes that may or may not improve the feed ingredients' nutritional value. Pig performance and nutrient digestibility are often improved by thermal processing, which also increases protein denaturation, fibre solubalization, and starch gelatinization and utilisation. The nutritional content of processed feeds is decreased as a result of Maillard reactions, oxidation of lipids, loss of vitamins, and additional feed additives, among other detrimental effects of high temperature and prolonged processing. Therefore, before making official recommendations for processing parameters, feed millers should take into account the relationship between animal nutrition and processing.

description: Our goal is to determine the stellar and wind properties of seven O stars in the cluster NGC2244 and three O stars in the OB association MonOB2. These properties give us insight into the mass loss rates of O stars, allow us to check the validity of rotational mixing in massive stars, and to better understand the effects of the ionizing flux and wind mechanical energy release on the surrounding interstellar medium and its influence on triggered star formation. We collect optical and UV spectra of the target stars which are analyzed by means of atmosphere models computed with the code CMFGEN. The spectra of binary stars are disentangled and the components are studied separately. All stars have an evolutionary age less than 5 million years, with the most massive stars being among the youngest. Nitrogen surface abundances show no clear relation with projected rotational velocities. Binaries and single stars show the same range of enrichment. This is attributed to the youth and/or wide separation of the binary systems in which the components have not (yet) experienced strong interaction. A clear trend of larger enrichment in higher luminosity objects is observed, consistent with what evolutionary models with rotation predict for a population of O stars at a given age. We confirm the weakness of winds in late O dwarfs. In general, mass loss rates derived from UV lines are lower than mass loss rates obtained from Ha. The UV mass loss rates are even lower than the single line driving limit in the latest type dwarfs. These issues are discussed in the context of the structure of massive stars winds. The evolutionary and spectroscopic masses are in agreement above 25 Msun but the uncertainties are large. Below this threshold, the few late-type O stars studied here indicate that the mass discrepancy still seems to hold.

description: In December 2009, the bright blazar, 3C 454.3 exhibited a strong outburst in the optical, X-ray and gamma-ray regions. We performed photometric and polarimetric monitoring of this outburst in the optical and near-infrared bands with TRISPEC and HOWPol attached to the Kanata telescope. We also observed this outburst in the infrared band with AKARI, and the radio band with the 32-m radio telescope of Yamaguchi University. The object was in an active state from JD 2455055 to 2455159. It was 1.3 mag brighter than its quiescent state before JD 2455055 in the optical band. After the end of the active state in JD 2455159, a prominent outburst was observed in all wavelengths. The outburst continued for two months. Our optical and nearinfrared polarimetric observations revealed that the position angle of the polarization (PA) apparently rotated clockwise by 240 degrees within 11 d in the active state (JD 2455063-2455074), and after this rotation, PA remained almost constant during our monitoring. In the outburst state, PA smoothly rotated counterclockwise by 350 degrees within 35 d (JD 2455157-2455192). Thus, we detected two distinct rotation events of polarization vector in opposite directions. We discuss these two events compared with the past rotation events observed in 2005, 2007 and 2008.

description: Cet escape game implique la collaboration de 2 équipes qui sont dans 2 salles différentes mais qui communiquent par une petite pièce centrale lorsqu'ils en ont trouvé l'accès. Pour accueillir les joueurs, il faut donc 2 maitres du jeu : un chef de la police scientifique et un chercheur du laboratoire ayant une collègue actuellement hospitalisée et un autre collègue malheureusement décédé récemment. Une bactérie génétiquement modifiée par Crispr-Cas9 semble être la responsable. Ces maitres du jeu ont besoin d'aide pour trouver un antidote en moins de 40 minutes. Fouille, manipulation, réflexion et collaboration sont essentielles. Vous trouverez toutes les informations pour mettre en place cet escape game pédagogique pour une douzaine de personnes et une quarantaine de minutes de jeu.
Il s'agit du 4ème escape game pédagogique créé lors de l'unité d'enseignement "Escape Game Moléculaire" de l'Université Paris Cité (2022-2023).
Survey of Kozai Dynamics Beyond Neptune

description: We study the Kozai dynamics affecting the orbital evolution of transneptunian objects being captured or not in MMR with Neptune. We provide energy level maps of the type (ω,q) describing the possible orbital paths from Neptune up to semimajor axis of hundreds of AU. The dynamics for non resonant TNOs with perihelion distances, q, outside Neptune's orbit, a_N, is quite different from the dynamics of TNOs with q < a_N, already studied in previous works. While for the last case there are stable equilibrium points at ω = 0\circ, 90\circ, 180\circ and 270\circ in a wide range of orbital inclinations, for the former case it appears a family of stable equilibrium points only at a specific value of the orbital inclination, i \sim 62\circ, that we call critical inclination. We show this family of equilibrium points is generated by a mechanism analogue to which drives the dynamics of an artificial satellite perturbed by an oblate planet. The planetary system also generates an oscillation in the longitude of the perihelion of the TNOs with i \sim 46\circ, being Eris a paradigmatic case. We discuss how the resonant condition with Neptune modify the energy level curves and the location of equilibrium points. The asymmetric librations of resonances of the type 1:N generate a distortion in the energy level curves and in the resulting location of the equilibrium points in the phase space (ω,q). We study the effect on the Kozai dynamics due to the diffusion process in "a" that occurs in the Scattered Disk. We show that a minimum orbital inclination is required to allow substantial variations in perihelion distances once the object is captured in MMR and that minimum inclination is greater for greater semimajor axis.
