Streamflow monitoring in a time of change : using image velocimetry methods on citizen videos of the November 2021 flooding in Merritt, British Columbia
Creators: name: Yang, Jian Song
Publisher: name: University of British Columbia
Year: 2023

description: The atmospheric river event in November 2021 is one of the costliest natural disasters in Canadian history. Among others, the Coldwater River in Merritt, British Columbia breached its banks on November 15th, 2021, resulting in extensive damage to the infrastructure and total evacuation of the residents. Estimating the magnitude of this flood is difficult, as it damaged the local flow monitoring station and altered the surrounding landscape. Parts of this flooding event, including the flow close to its peak, were filmed by local residents using mobile devices or drones. Though with significant perspective distortion and imprecision, they still provide valuable information on this extreme event, which would have otherwise been neglected. This study aims to apply image velocimetry techniques to some of these videos, with limited resources and outdated geodata, for reconstructing surface velocities and discharges during the flood. The analysis method consists of using Large Scale Particle Image Velocimetry and Farneback optical flow on the original clips where possible. The extreme and post-event nature of the flood requires changes to many aspects of the conventional image velocimetry workflow. Ground Control Points are identified in the videos, then geolocated or surveyed after the flood, for rectification of raw velocities from image to real-world coordinates. This conservative measure allows unlimited iterations in orthorectification. Discharges are then calculated using surveyed transects, with water surface elevations estimated from the video frames. Results from both methods show a maximum of 20% difference against estimates from from the Water Survey of Canada, proving the versatility of image velocimetry under adverse conditions. Uncertainties in one standard deviation of all four transect discharges, at a maximum of 47%, are higher than expected but still reasonable, likely due to deviations in estimating the stage directly from the videos of poor quality. Extensive testing on the Farneback method show a different response on velocity estimation, especially when surface features are not as rich as those from flooding. Edge pixels are tested and proven to be a promising metric for quantifying natural surface features, without the need for image binarization which does not work well with dense optical flow.

description: We study the fluctuations of the autocorrelation and autoresponse functions and, in particular, their variances and co-variance. In a first general part of the Article, we show the equivalence of the variance of the response function with the second-order susceptibility of a composite operator, and we derive an equilibrium fluctuation-dissipation theorem beyond-linear order relating it to the other variances. In a second part of the paper we apply the formalism to the study to non-disordered ferromagnets, in equilibrium or in the coarsening kinetics following a critical or sub-critical quench. We show numerically that the variances and the non-linear susceptibility obey scaling with respect to the coherence length $ξ$ in equilibrium, and with respect to the growing length $L(t)$ after a quench, similarly to what is known for the autocorrelation and the autoresponse functions.

description: The final state interaction of pions in the decay $K^\pm\to π^+π^-e^\pmν$ allows to obtain the value of the isospin and angular momentum zero pion-pion scattering length $a_0^0$. To extract this quantity from experimental data the radiative corrections (RC) have to be taken into account. Basing on the lowest order results and the factorization hypothesis, we get the expressions for RC in the leading and next-to leading logarithmical approximation. It is shown that the decay width dependence on the lepton mass $m_e$ through the parameter $σ=\fracα{2π}\br{\ln\frac{M^2}{m_e^2}-1}$ has a standard form of the Drell-Yan process and is proportional to the Sommerfeld-Sakharov factor. The numerical estimations are presented.

Fostering Justification: A Case Study of Preservice Teachers, Proof-Related Tasks, and Manipulatives
Creators: name: Bostic, Jonathan D.
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2016

description: Instruction promoting reasoning and proof should be a part of K-12 mathematics teaching. Preservice teachers (PSTs) need mathematics content instruction that helps them construct valid justifications for mathematical notions and develop positive perceptions of proof. This case study describes instruction with proof-related tasks and manipulatives for middle-grades PSTs that draws on developmentally appropriate modes of argument representation. The purpose of the instruction was for PSTs to explore mathematics content through a lens of how a middle-grades teacher might use manipulatives to engage students in justifying mathematical statements in proof- related tasks. Results indicate that this instruction supported PSTs to justify mathematical ideas and that PSTs characterized their experiences positively. PSTs perceived proof in ways echoed in past literature, saw connections between the PSTs’ instruction and future middle-grades classroom instruction they might enact, and identified the role of struggle while engaging in proof-related tasks. This case study provides ideas for mathematics content instructors to develop PSTs’ understanding of mathematics through instruction that prepares them to engage their future K-12 students in proof-related tasks.

Venous Congestive Myelopathy due to Chronic Inferior Vena Cava Thrombosis Treated with Endovascular Stenting: Case Report and Review of the Literature
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Authors have no conflict of interest to disclose. Objective—Impaired inferior vena cava (IVC) outflow can lead to collateralization of blood to the valveless epidural venous plexus, causing epidural venous engorgement and venous congestion. Herein we describe a case of chronic IVC thrombosis presenting as venous congestive myelopathy treated with angioplasty and endovascular stenting. The pathophysiological mechanisms of cord injury are hypothesized, and IVC stenting application is evaluated. Methods—Case report and review of the literature. Results—IVC outflow obstruction has only rarely been associated with neurologic dysfunction, with reports of lumbosacral nerve root compression in the cases of IVC agenesis, compression, or occlusion. Although endovascular angioplasty with stenting is emerging as a leading treatment option for chronic IVC thrombosis, its use to treat neurologic complications is limited to one case report for intractable sciatica. Our case is the first description of IVC thrombosis presenting with venous congestive myelopathy, and treated successfully with IVC stenting. Conclusion—Venous congestive myelopathy should be seen as a broader clinical condition, including not only typical dural arteriovenous fistulas, but also disorders of venous outflow. Therefore, identifying a rare, but potentially treatable, etiology is important to avoid permanent neurologic deficits. IVC stenting is proposed as a novel and effective treatment approach.

description: Teaching for social justice is a critical pedagogy used to empower students to be social agents in the world they live. This critical pedagogy has extended to mathematics education. Over the last decade, mathematics education researchers have conceptualized what it means to teach mathematics for social justice, but little is known about preservice teachers’ perspectives on this topic. The purpose of this study was to examine elementary preservice teachers’ conceptions of teaching mathematics for social justice at the beginning and end of a mathematics methods course. Preservice elementary teachers (n = 230) enrolled in mathematics methods coursework at three universities across the United States described what it meant to teach mathematics for social justice in response to an open-ended question on the Mathematics Experiences and Conceptions Surveys.

description: In a search for new phenomena in a signature suppressed in the standard model of elementary particles (SM), we compare the inclusive production of events containing a lepton, a photon, significant transverse momentum imbalance (MET), and a jet identified as containing a b-quark, to SM predictions. The search uses data produced in proton-antiproton collisions at 1.96 TeV corresponding to 1.9 fb-1 of integrated luminosity taken with the CDF detector at the Fermilab Tevatron. We find 28 lepton+photon+MET+b events versus an expectation of 31.0+4.1/-3.5 events. If we further require events to contain at least three jets and large total transverse energy, simulations predict that the largest SM source is top-quark pair production with an additional radiated photon, ttbar+photon. In the data we observe 16 ttbar+photon candidate events versus an expectation from SM sources of 11.2+2.3/-2.1. Assuming the difference between the observed number and the predicted non-top-quark total is due to SM top quark production, we estimate the ttg cross section to be 0.15 +- 0.08 pb.

description: Research is needed to understand the impact of high-stakes testing on teachers’ practices and consequently on their students, particularly at schools that serve large numbers of low-income students and students of color. In this research study, we examined how a state’s annual high-stakes test and administrative mandates influenced the assessment practices of mathematics teachers at a highly diverse urban high school. Among the most compelling findings was that students at Chavez High (a pseudonym) were labeled based upon their test performance, that this label tended to persist at the school, and that instructional decisions were made based upon these labels. This practice of attaching a label to students based upon their performance on the high-stakes test constructed some students as less capable than others in mathematics. Such practices contribute to the historic legacy in the U.S. of denying poor students and students of color access to a challenging education in mathematics.

description: Global health has been greatly impacted by vaccines. Smallpox, rinderpest, and several other major infections have been eradicated. A variety of infectious diseases of childhood have been significantly improved by whom in the past decade. As polio has been virtually eradicated, and measles has been controlled successfully, it may also be eradicated soon. Vaccines can prevent infections such as pneumonia and diarrhoea which cause 6.6 million deaths each year. Due to new pneumococcal conjugate vaccines and rotavirus vaccines, childhood mortality is expected to decline further. As of now, malaria, tuberculosis, and HIV vaccines have had modest success. Vaccinations that stimulate different immune systems and it may be the most effective way to prevent these infections. Reverse and structural vaccinology have revealed novel antigen candidates and molecular immunology has led to the formulation of promising adjuvants. Gene expression profiles and immune parameters in patients, vaccinees and healthy controls have formed the basis for biosignatures that will provide guidelines for future vaccine design. On a long-term basis, vaccines may prevent or modulate diseases other than infectious diseases. It is already possible to develop cancer vaccines, and in the future it will be possible to develop vaccines for addictions, diabetes, hypertension, and Alzheimer's disease as well.

description: We present new mid-infrared ($5 - 35μ$m) and ultraviolet (1539 -- 2316 Å) observations of the interacting galaxy system Arp 143 (NGC 2444/2445) from the Spitzer Space Telescope and GALEX. In this system, the central nucleus of NGC 2445 is surrounded by knots of massive star-formation in a ring-like structure. We find unusually strong emission from warm H$_2$ associated with an expanding shock wave between the nucleus and the western knots. At this ridge, the flux ratio between H$_2$ and PAH emission is nearly ten times higher than in the nucleus. Arp 143 is one of the most extreme cases known in that regard. From our multi-wavelength data we derive a narrow age range of the star-forming knots between 2 Myr and 7.5 Myr, suggesting that the ring of knots was formed almost simultaneously in response to the shock wave traced by the H$_2$ emission. However, the knots can be further subdivided in two age groups: those with an age of 2--4 Myr (knots A, C, E, and F), which are associated with $8μ$m emission from PAHs, and those with an age of 7-8 Myr (knots D and G), which show little or no $8μ$m emission shells surrounding them. We attribute this finding to an ageing effect of the massive clusters which, after about 6 Myr, no longer excite the PAHs surrounding the knots.

'Living with goodbyes' ending therapy: an exploration of the psychotherapist's task
Creators: name: Dow, Rhiannon
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: The ending is an important event in child psychotherapy. During this phase, earlier unsatisfactory goodbyes are often revived. It is hoped that patients, given the opportunity to revisit these goodbyes in the therapy, will be able to untangle what belongs in the past and what belongs in the present. Ideally, the therapeutic work and its ending should remain alive in the patient's internal world, and can be drawn upon at times in the future, increasing the patient's reflective capacity and their capacity to embrace loss and all that entails (Klein, 195011975). In the historical psychoanalytic literature and training, it is striking that ending therapy receives less attention than it deserves. Ending therapy arouses powerful anxieties for the patient and therapist alike and it seems that avoidance is often sought to defend against these painful feelings. Wittenberg (1999) states that it is because of this that ending therapy as a topic tends to be neglected. To develop a greater understanding of endings in child psychotherapy, a qualitative study was undertaken. Three experienced child psychotherapists registered with the Victorian Child Psychotherapy Association were interviewed about their experience when ending therapy. The semi structured interview explored factors that facilitate and disrupt a "good enough goodbye" in child psychotherapy, and how beginning psychotherapists may be better prepared for this important task. A thematic analysis was applied to the transcripts of the interviews and major themes emerged. These included: death, emotions, holding on and letting go, what facilitates a good enough goodbye, what disrupts a good enough goodbye, the scaffolds that assist the psychotherapist, and suggestions for psychotherapy trainings. It is hoped that these key themes may help better inform child psychotherapy training and in turn assist therapists in preparing to manage the powerful emotions aroused when saying goodbye.

description: This article compares the views of teachers and professors about the transition from secondary mathematics to tertiary calculus. Quantitative analysis revealed five categories where teachers and professors differed significantly in the relative frequency of addressing them. Using the rite of passage theory, the separation and incorporation phases were investigated by carrying out thematic analyses on these five categories. For the professors, the analysis revealed specific content within algebra and precalculus that they viewed as vital preparation for students’ tertiary calculus success. For the teachers, the analysis highlighted the classroom environment realities of teaching in the separation phase. The rite of passage and professional turf theories are used to discuss and interpret the findings.

Graph neural networks for traffic prediction and resource allocation in 6G wireless systems
Creators: name: Mehrabian, Ali
Publisher: name: University of British Columbia
Year: 2023

description: Predictive analysis of traffic demands for the sixth-generation (6G) wireless systems plays an important role in network resource provisioning. As 6G networks aim to support various applications, forecasting traffic demands accurately is instrumental for efficient resource allocation and ensuring high-quality user experience in dynamic wireless environments. Moreover, high data rate requirements of content-rich applications necessitate the exploration of emerging technologies. This study focuses on two such technologies: terahertz (THz) band communication and reconfigurable intelligent surface (RIS). The utilization of the THz band enables wireless systems to achieve ultra-high data rates, while RIS can improve the coverage service of wireless networks. However, these technologies introduce previously uncharted challenges, which require novel resource allocation approaches to address them and fully leverage their potential. In this thesis, we propose graph neural network (GNN) learning algorithms for traffic demand prediction and network resource optimization in order to improve the performance of 6G wireless systems. First, we propose a dynamic Bernstein graph recurrent network (DBGRN). The proposed learning algorithm utilizes the information in the spatial, temporal, and spectral domains to predict traffic in wireless cellular networks. The experimental results using a real-world traffic dataset show that the proposed DBGRN outperforms four state-of-the-art baseline models, and provides a lower root mean squared error (RMSE) and mean absolute error (MAE). Second, we study the sum-rate maximization problem with quality-of-service (QoS) constraints in RIS-aided multiuser multiple-input multiple-output (MU-MIMO) THz systems. We propose a metapath-based heterogeneous graph-transformer network (MHGphormer) to jointly optimize the precoding, RIS phase shifts, and THz sub-bands bandwidth allocation. Simulation results show that our proposed MHGphormer achieves a higher system sum-rate with faster convergence when compared with two other learning-based algorithms.

description:

Faïza Guène’s sixth novel La discrétion focuses on a Maghreb Muslim woman who, having migrated to France, is trying to reconstruct her personal and family history. It is a memoir whose aim is to make the experiences of first-generation migrants an integral part of cultural memory. This search for identity concerns the children of those migrants who try to relate to a fragmented, often suppressed family history they did not experience themselves, but whose burden they nonetheless inherited. The aim of this article will be to prove that what allows both the protagonist of the story and who tells it to free themselves from this overwhelming past is in fact the narrative itself, a process of identity construction with which each author is confronted.

description: This thesis investigates the question of whether sensory motor play has a significant role to play in child psychotherapy with children who have experienced complex trauma. The literature review incorporates a range of relevant theoretical fields, including Neurobiology, Infant Mental Health, Psychoanalytic Theory, Child Psychotherapy and Occupational Therapy. Hermaneutic phenomenology, in particular Ricouer's emphasis on narrative analysis, forms the foundation for the research design The researcher interviewed 5 experienced child psychotherapists practising in metropolitan Melbourne to explore their views around the role of sensory motor play in child psychotherapy with traumatized children in mental health settings. The practitioners each confirmed the benefits they had observed in their clinical practice in utilizing sensory motor activities to provide assistance with arousal modulation, which facilitated a sense of safety and potential connectedness in the therapeutic relationship. Some participants also stated that the sensory motor play provided developmental opportunities which child patients had missed out on in their histories of childhood neglect and complex trauma. Thematic analysis highlighted 4 areas raised by the participants including-arousal regulation and phases involved in the development of the therapeutic relationship for children who have experienced complex trauma; the role of the therapist as developmental object; understanding mess and regressive sensory motor play as a means, if not the primary means, of communication; and the' act of being with' in the therapeutic relationship. Limitations of the study included the small cohort and the pre-existing relationships existing between the research and some of the participants. The researcher expressed the hope that future collaborations occur between the fields of Occupational Therapy and Child Psychotherapy to further explore the therapeutic benefits of sensory motor play as part of child psychotherapy treatment for children who have experienced Complex Trauma.
"We were waiting for you": understanding a mother's innate expectation for engagement with an infant observation
Creators: name: Allen, Cassie
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: Bekos (2007) and Watillon (2002) were pioneers in undertaking empirical research to better understand the mother's motivation for participation in an infant observation. This thesis aims to build on the limited research in the field on the experience of the observed mother in an infant observation, and to consider the innate and instinctual processes of the mother, and her anticipation or expectation for engagement with the observation. The data was drawn from the written recordings of one infant observation and was not obtained with a specific hypothesis in mind; however examination of the data collected generated the hypothesis. It was through a qualitative analysis of the mother's verbal and non verbal communications that the phenomenon of the mother's innate expectation for engagement with the observation was identified. In the absence of existing literature speaking to this phenomenon, Klein's (1959) premise of the infant having an innate unconscious awareness of the mother and mother role from birth forms the theoretical framework for this thesis. In the reported observation the mother presented with a similar unconscious awareness of the observer and it is hypothesised that the mother had been expecting or awaiting the arrival of both the observer and her baby. It is concluded that whilst the phenomenon of the mother's innate expectation for engagement with the observation has not previously been identified in the literature, this anticipation and expectation of 'another' may have significant implications as to how the community supports new mothers. These findings suggest further research on a broader scale is required.

description: An estimated 90% of all confirmed COVID-19 cases occur in rural and urban areas around the world, where all industries and sectors have been severely impacted. The ongoing COVID-19 pandemic has highlighted and intensified many of the difficulties and uncertainties local governments face in carrying out their responsibilities. Apart from restoring normalcy, local governments in the National Capital Region face specific challenges, as they must double their efforts and interventions to achieve the Sustainable Development Goals (SDGs), as well as restore and reinforce community resilience in both short and long-term response and action.
 Local government plays a significant role in providing social services in normal times and ensures that these public services are accessible in times of adversity and distress, as well as acting as first responders in disaster prevention, rescue, and restoration.
 While the world has not yet crossed everyone, and some issues remain unresolved, the author agrees that unprecedented decisions and good practices from neighboring countries should have been taken to protect citizens, especially the most vulnerable.
 The author examined and reviewed the various mechanisms used by various local governments in Metro Manila, as well as the SDG framework, to analyze the challenges and good practices for local responses to the pandemic and mitigating its effects.
 The author finds that identifying the challenges faced by various local governments in Metro Manila as well as how they deal with these challenges and recognizing their good practices would aid local governments in long-term sustainability planning and development.

description: Mesoscopic particle based fluid models, such as dissipative particle dynamics, are usually assumed to be coarse-grained representations of an underlying microscopic fluid. A fundamental question is whether there exists a map from microscopic particles in these systems to the corresponding coarse-grained particles, such that the coarse-grained system has the same bulk and transport properties as the underlying system. In this letter, we investigate the coarse-graining of microscopic fluids using a Voronoi type projection that has been suggested in several studies. The simulations show that the projection fails in defining coarse-grained particles that have a physically meaningful connection to the microscopic fluid. In particular, the Voronoi projection produces identical coarse-grained equilibrium properties when applied to systems with different microscopic interactions and different bulk properties.

description: This paper uses the invariance principle to solve the incidental parameter problem of [Econometrica 16 (1948) 1--32]. We seek group actions that preserve the structural parameter and yield a maximal invariant in the parameter space with fixed dimension. M-estimation from the likelihood of the maximal invariant statistic yields the maximum invariant likelihood estimator (MILE). Consistency of MILE for cases in which the likelihood of the maximal invariant is the product of marginal likelihoods is straightforward. We illustrate this result with a stationary autoregressive model with fixed effects and an agent-specific monotonic transformation model. Asymptotic properties of MILE, when the likelihood of the maximal invariant does not factorize, remain an open question. We are able to provide consistent, asymptotically normal and efficient results of MILE when invariance yields Wishart distributions. Two examples are an instrumental variable (IV) model and a dynamic panel data model with fixed effects.

A Living Metaphor of Differentiation: A Meta-Ethnography of Cognitively Guided Instruction in the Elementary Classroom
Creators: name: Baker, Katherine
name: Harter, Meghan Evelynne
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2015

description: This meta-ethnography explores qualitative studies around the Cognitively Guided Instruction (CGI) framework of mathematics and illustrates how CGI epitomizes differentiation. The meta-ethnographic process is used to synthesize CGI as differentiation, specifically within the elementary mathematics classroom. Thomas P. Carpenter is credited as one of the foundational researchers of this instructional model, along with his team of Fennema, Franke, Levi, and Empson. Six qualitative pieces from this author group are synthesized to create a reciprocal translation, described by Noblit and Hare (1988) as a generation of a metaphor across similar studies. In this case, the pieces work together to form a metaphor of differentiation across the themes of student centered pacing, alternative forms of assessment and teacher scaffolding.

In-Class Purposes of Flipped Mathematics Educators
Creators: name: Eisenhut, Lindsay A.
name: Taylor, Cynthia E.
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2015

description: This paper provides empirical findings from a study that examined how three grade 7-12 flipped mathematics educators utilized class time when implementing a flipped learning model. Additionally, the researchers investigated the educators' purposes for various in-class tasks as well as their general use of class time. The data revealed flipped mathematics educators engaged students in multiple mathematical activities throughout each class period so as to provide the opportunity for students to develop their (1) introductory content knowledge and procedural fluency, (2) conceptual understanding of mathematical topics, and (3) mathematical problem-solving abilities. Implications from this study contribute to the literature on secondary mathematics classroom teachers’ purposes and provide insights into the classroom practices of flipped mathematics educators.

A Validity Study: Attitudes towards Statistics among Japanese College Students
Creators: name: Satake, Eike
Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2015

description: This cross-cultural study investigated the relationship between attitudes toward statistics (ATS) and course achievement (CA) among Japanese college students. The sample consisted of 135 male and 134 female students from the first two-year liberal arts program of a four-year college in Tokyo, Japan. Attitudes about statistics were measured using the Wise Attitudes Toward Statistics Scale (ATSS). A Japanese version of the ATSS was developed by a team of bilingual experts in Japanese studies and linguistics. The final course grade of the participants served as the measure of course achievement. Data analyses include factor analysis, reliability estimates for the ATSS, correlation analyses of CA, and the ATSS factor scores.

A mass-loss rate determination for zeta Puppis from the quantitative analysis of X-ray emission line profiles

description: We fit every emission line in the high-resolution Chandra grating spectrum of zeta Pup with an empirical line profile model that accounts for the effects of Doppler broadening and attenuation by the bulk wind. For each of sixteen lines or line complexes that can be reliably measured, we determine a best-fitting fiducial optical depth, tau_* = kappa*Mdot/4{pi}R_{\ast}v_{\infty}, and place confidence limits on this parameter. These sixteen lines include seven that have not previously been reported on in the literature. The extended wavelength range of these lines allows us to infer, for the first time, a clear increase in tau_* with line wavelength, as expected from the wavelength increase of bound-free absorption opacity. The small overall values of tau_*, reflected in the rather modest asymmetry in the line profiles, can moreover all be fit simultaneously by simply assuming a moderate mass-loss rate of 3.5 \pm 0.3 \times 10^{-6} Msun/yr, without any need to invoke porosity effects in the wind. The quoted uncertainty is statistical, but the largest source of uncertainty in the derived mass-loss rate is due to the uncertainty in the elemental abundances of zeta Pup, which affects the continuum opacity of the wind, and which we estimate to be a factor of two. Even so, the mass-loss rate we find is significantly below the most recent smooth-wind H-alpha mass-loss rate determinations for zeta Pup, but is in line with newer determinations that account for small-scale wind clumping. If zeta Pup is representative of other massive stars, these results will have important implications for stellar and galactic evolution.

description: The use of emulsions as particles detector has a long and successful life. The recent development of fast automatized analysis systems has allowed the use of huge amount of emulsions films with no precedence in the history of particle physics. The OPERA experiment, running in the underground Laboratori Nazionali del Gran Sasso (LNGS), for the confirmation of the neutrino oscillation in the $ν_μ\toν_{tau}$ channel, is "the major" of these experiments. The experimental technique, the strategy and the first results of the experiment are presented.

Development of a novel device for hemostatic powder delivery treating gastrointestinal bleedings
Creators: name: Mavroudis, Angelos
Publisher: name: University of British Columbia
Year: 2023

description: Severe gastrointestinal hemorrhaging presents a complex challenge that can lead to potentially fatal outcomes. Although existing medical solutions offer some assistance in managing internal bleeding, they are unreliable due to their limitations. Recent work on innovative hemostatic powders has shown promising results in effectively controlling bleeding without imposing any risk to the patient. However, to efficiently deliver this hemostatic agent, an optimized delivery system is required. The hemostatic powder is characterized by adhesive properties that negatively impact its flowability. This research aims to create a prototype of a medical device to test and improve the flow of an adhesive hemostatic powder through a 0.002 m in diameter and 1.47 m in length catheter. A detailed experimental analysis is performed to understand which parameters and how they affect the performance of the delivery system. In the experiments, the performance of the delivery system is characterized based on the delivery time and the powder mass deposition at the outlet of the catheter. A high-velocity gas flow is responsible for transporting the powder through a catheter and into a sealed container. A pressure regulator regulates the maximum pressure of the system at 68 kPa (10 psi), while the flow rate is adjusted using a gas flow regulator. Three different flow rates are examined in the experimental part of this work: 0.37 m³/h, 0.31 m³/h, and 0.23 m³/h. Furthermore, to improve the device, different designs are being tested. The effects of dimensional changes on powder flowability are being examined with respect to the efficiency of powder delivery through the catheter. A primary modeling approach for turbulent and dense gas-solid multiphase flows is being presented using computer-aided engineering. Computational fluid dynamics (CFD) and discrete element methods (DEM) are combined to develop a computational model of the granular flow. This model is defined by specific attributes of the powder and the carrying fluid. The numerical results verification is supported by experimental data.
