description: Using deep, high-spatial-resolution imaging from the Hubble Space Telescope/Advanced Camera for Surveys (HST/ACS) Coma Cluster Treasury Survey, we determine colour profiles of early-type galaxies in the Coma cluster. From 176 galaxies brighter than MF814W(AB)=-15mag that are either spectroscopically confirmed members of Coma or identified by eye as likely members from their low surface brightness, data are provided for 142 early-type galaxies. Typically, colour profiles are linear against log(R), sometimes with a nuclear region of distinct, often bluer colour associated with nuclear clusters. Colour gradients are determined for the regions outside the nuclear components. We find that almost all colour gradients are negative, both for elliptical and for lenticular galaxies. Most likely, earlier studies that report positive colour gradients in dwarf galaxies are affected by the bluer colours of the nuclear clusters, underlining that high-resolution data are essential to disentangle the colour properties of the different morphological components in galaxies. Colour gradients of dwarf galaxies form a continuous sequence with those of elliptical galaxies, becoming shallower towards fainter magnitudes. Interpreting the colours as metallicity tracers, our data suggest that dwarfs as well as giant early-type galaxies in the Coma cluster are less metal rich in their outer parts. We do not find evidence for environmental influence on the gradients, although we note that most of our galaxies are found in the central regions of the cluster. For a subset of galaxies with known morphological types, S0 galaxies have less steep gradients than elliptical galaxies.
The homeric êthos, Cimonian-Periclean rivalry and the speeches of Pericles in Thucydides' account of the Athenian-Peloponnesian war.

description: The speeches in Thucydides have long been a source of lively historical controversy. Many scholars have discounted their historical veracity in differing degrees. This has been true even of the speeches of Pericles, particularly his famous Funeral Oration, although scholarly objections to the content and tone of the Periclean speeches have largely been of a purely subjective nature. However, an examination of how the Homeric h&d5; ,qov , with its stringent demand for the studied cultivation and possession of timh&d12; and a ,r3t h&d12; , functions within the speeches of Pericles as a key motivating force for the steadfast pursuance of a highly aggressive foreign policy, sheds an interesting light on the question of the historical nature of the speeches and the outbreak of the Athenian-Peloponnesian War. In conjunction with this "Homeric reading" to the speeches, a further consideration of the more realistic analyses of modern manifestations of Realpolitik in the sphere of international politics and diplomacy, adduces additional support for the acceptance of the speeches of Pericles as important forms of historical evidence for the basic workings of Machtpolitik.
Geology of the Mount Costigan lead-zinc deposit, west-central New Brunswick.
Creators: name: Cox, Nicholas David.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1990
Subjects: subject: Geology.

description: The Mount Costigan Pb-Zn deposit is located about 40km east of Plaster Rock, New Brunswick within the Early Devonian Costigan Mountain Formation, in the Matapedia Cover Sequence (formerly the Cialeur Bay Synclinorium). It occurs about 250m east of the summit of Mount Costigan within a series of brecciated and unbrecciated crystal and lapilli tuff, rhyolite and minor siltstone which are exposed in six trenches (North, South, East, West, Southwest and Central). To the west the Costigan Mountain Formation is overlain by the Wapske Formation. The most significant feature of the deposit is the large amount of brecciation, which, in the Central Trench, also serves as the main sulphide host. Petrographic studies indicate that the breccia consists of angular to subangular blocks of massive and banded crystal tuff, massive to spherulitic to flow-banded rhyolite and minor lapilli tuff. The Mount Costigan deposit is interpreted to represent a base metal variety of epithermal deposit. (Abstract shortened by UMI.)

description: Background: Poor nurse-patient relationship poses an obstacle to care delivery, jeopardizing patient experience and patient care outcomes. Measuring nurse-patient relationship is challenging given its multi-dimensional nature and a lack of well-established scales. Purpose: This study aimed to develop a multi-dimensional scale measuring nurse-patient relationship in China. Methods: A preliminary scale was constructed based on the existing literature and Delphi consultations with 12 nursing experts. The face validity of the scale was tested through a survey of 45 clinical nurses. This was followed by a validation study on 620 clinical nurses. Cronbach’s α, content validity and known-group validity of the scale were assessed. The study sample was further divided into two for Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA), respectively, to assess the construct validity of the scale. Results: The Nurse-Patient Relationship Scale (NPRS) containing 23 items was developed and validated, measuring five dimensions: nursing behavior, nurse understanding and respect for patient, patient misunderstanding and mistrust in nurse, communication with patient, and interaction with patient. The Cronbach’s α of the NPRS ranged from 0.725 to 0.932, indicating high internal consistency. The CFA showed excellent fitness of data into the five-factor structure: χ2/df = 2.431, GFI = 0.933, TLI = 0.923, CFI = 0.939, IFI = 0.923, RMSEA = 0.070. Good content and construct validity are demonstrated through expert consensus and psychometric tests. Conclusion: The NPRS is a valid tool measuring nurse-patient relationship in China.
State space estimation of wireless fading channels.

Subjects: subject: Engineering, Electronics and Electrical.

description: This thesis presents a state space approach to optimal estimation of channel processes, such as inphase, quadrature, square envelope, phase, etc., of wireless fading channels. The models are derived from the Doppler power spectral density using factorization and realization techniques. Several simulations are performed when the channel is Rayleigh and Ricean distributed under both flat and frequency-selective fading assumptions. The simulation studies illustrate the tracking properties of the inphase, quadrature and square envelope estimators for various received signal-to-noise ratios.

description: Background: Perceived social status (PSS) is a measure of social status, reflecting cumulative lifetime effects of relative social status based on available resources and life experiences. PSS is hypothesized to better capture social status compared to traditional socioeconomic status (SES) measures (i.e., education, occupation, and income). This dissertation investigated the association of PSS with oral health.
description: Methods: This dissertation is a series of three studies. Study I and study II analyzed a survey administered to a random sample of low-income adults with Medicaid insurance in the state of Iowa (N=18,000). Study III used a qualitative approach with semi-structured one-on-one interviews of emerging young adults (aged 18-25-years) seeking dental care to evaluated PSS and motivators to seeking dental care.
description: Results: In study I, PSS was found to be positively associated (ß=.16, p<.0001) with self-reported oral health when controlling for demographic characteristics, as well as with self-reported dental utilization in study II. Additionally, individuals with higher PSS more often mentioned having routine dental care in childhood and strong personal drive to seek dental care in adulthood as determined in study III.
description: Conclusions: Our research along with previous studies have demonstrated that PSS is associated with oral health outcomes and healthy behaviors. Exploring these factors longitudinally is critical, particularly across the lifespan. We discovered that emerging young adults face additional challenges to obtaining care. Future directions include exploring whether PSS changes as individuals age and if that impacts care-seeking behaviors.

description: Street soccer has been played in a socially deprived neighborhood, Vancouver’s Downtown Eastside, since 2008. Significant social and physical benefits have been self-reported by players, but the impact on its volunteers has never been assessed. Recent qualitative studies suggest that volunteering in grassroots sport-for-development initiatives contributes to the development of social capital by mediating the formation of relationships between people from different social groups, leading to mutual understanding and the development of positive feelings towards one another. Therefore, the aim of this study was to produce quantitative evaluations of volunteers’ changes in perception of street soccer players, of their perceived effects of street soccer on players, and of their perceived effects of street soccer on themselves. The results of our survey suggest several misconceptions about people affected by homelessness exist within the general community, specifically in regards to a possible underestimation of the metal health burden. Additionally, our data indicate that volunteering is helping to reduce stigma amounts volunteers, and that participation in this volunteering activity is conveying positive physical and psychological effects on volunteers. These findings support the use of sport for social inclusion, and as a means of gaining social capital for street soccer volunteers.

Noise Reduction

description: This thesis reviews three main approaches for enhancing the sensitivity of 2D IR measurements. The first approach consists of noise reduction by edge-pixel referencing along the probe axis. Results show this referencing scheme reduces experimental noise by 20× while preserving measurements of spectral diffusion. The second approach consists of least-squares fitting of the three-dimensional 2D IR waiting-time series to a lineshape model in place of center-line-slope analysis. Results show an 8-50× improvement in the precision of spectral diffusion measurements for model fitting over the center-line-slope method. The third approach consists of signal enhancement by several different means. Analysis of a basic model for ΔOD shows how several different factors each contribute to the signal strength, including the pump energy, the beam waist, the path length, and molar absorptivity and concentration of the analyte and solvent. I also discuss practical limits and difficulties associated with each factor. I additionally discuss signal enhancement by local-oscillator attenuation and work to date by others in the community on plasmonic enhancement of 2D IR signals, which are known to reach factors of 10² - 10⁷ in gain. I finally end with an analysis of how saturation places an ultimate limit on ΔOD, and furthermore, how the temperature jump due to absorption of the pump beam by the solvent can place a separate, practical limit on ΔOD.

Bifurcation analysis of a class of delay-differential equations with reflectional symmetry: Applications to ENSO.
Creators: name: Redmond, Brian F.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2002
Subjects: subject: Mathematics.

description: We consider a general class of first-order nonlinear delay-differential equations (DDEs) with reflectional symmetry, and study completely the bifurcations of the trivial equilibrium under some generic conditions on the Taylor coefficients of the DDE. Our analysis reveals a Hopf bifurcation curve terminating on a pitchfork bifurcation line at a codimension two Takens-Bogdanov point in parameter space. We compute the normal form coefficients of the reduced vector field on the centre manifold in terms of the Taylor coefficients of the original DDE, and in contrast to many previous bifurcation analyses of DDEs, we also compute the unfolding parameters in terms of these coefficients. For application purposes, this is important since one can now identify the possible asymptotic dynamics of the DDE near the bifurcation points by computing quantities which depend explicitly on the Taylor coefficients of the original DDE. We illustrate these results using simple model systems relevant to the areas of neural networks and atmospheric physics, and show that the results agree with numerical simulations. Finally, note that most of the results of this thesis have already been refereed and published elsewhere (see [26]).
Distributed Brillouin sensing using polarization-maintaining fibers with high measurement accuracy
Creators: name: Yu, Qinrong
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2006
Subjects: subject: Physics, Optics.

description: This thesis is a collection of studies on a distributed sensor based on Brillouin scattering using polarization maintaining (PM) fibers as well as single mode fibers. With a specially designed optical fiber circuit consisting of two polarizing beam splitters and polarization controllers, PM fibers were successfully used as sensing media for the Brillouin distributed sensor developed at the University of Ottawa. The use of a single axis of a PM fiber minimizes polarization effects and therefore improves the signal to noise ratio of the Brillouin spectrum and hence, the measurement resolution. The strain and temperature dependence of Brillouin frequency, intensity and bandwidth of three types of commercial PM fibers: PANDA, Bow-tie and Tiger were investigated. The main findings from these investigations are as follows: (1) in a PM fiber, the temperature dependence of the Brillouin frequency in the slow axis is the same as that in the fast axes, and so is the strain dependence, (2) the Brillouin spectrum bandwidth is strain and temperature dependent, and (3) PANDA PM fiber shows the greatest promise for use in sensing applications and Tiger fiber is not suitable for Brillouin sensing. The feasibility of simultaneously measuring strain and temperature using PM fibers was examined. The 2nd order partial derivative of the Stokes intensity with respect to frequency and position shows a maximum or minimum at the boundary between two different strained sections. This idea was used to locate the boundary between different strain regions. This provides a spatial location accuracy between 5 cm to 10 cm, which is better than the 20 cm pulse length used in the experiment. The influences of transient phonon (defined as when pulse width is shorter than the phonon relaxation time) relaxation on the Brillouin loss spectrum have been observed and investigated. The transient phonon field lasts longer than the nature phonon lifetime (∼10 ns). This transient phonon relaxation time is pump power and probe ER dependent, and it affects the strain, temperature, and location measurement accuracy.
How do brokerages’ digital engagement practices affect retail investor information processing and trading?

Subjects: public abstract

description: I examine how retail brokerages’ digital engagement practices (i.e., push notifications and data visualization) impact retail investor information processing and trading. In my first chapter, I investigate how retail brokerages’ push notifications impact retail investor trading. My identification strategy exploits that Robinhood automatically sends push notifications to its customers when the intraday return of a stock in their portfolio reaches +/- 5%. I document that push notifications significantly increase retail investor trading by at least 25% in the fifteen minutes following notifications relative to non-retail investor trading. Further, retail investors respond to the notifications in a contrarian manner. Placebo analyses using Robinhood outages and an alternative notification threshold support these inferences. Notably, I find that aggregate retail informativeness increases following positive push notifications and does not change following negative push notifications.
description: In my second chapter, I investigate how the visual display of earnings information impacts retail investor information processing. My identification strategy exploits a shock to the attention paid to information displayed on Robinhood caused by push notifications. I find that retail investors incorporate visual earnings information in their trades. Retail investors use visual earnings to identify and purchase stocks with high risk-adjusted future returns following positive notifications but stocks with lottery-like future returns following negative notifications, behavior consistent with prospect theory preferences that differ across gains and losses. A difference-in-differences analysis around the introduction of earnings information on Robinhood and a placebo analysis using Robinhood outages support these inferences. Overall, my results show that data visualization can increase retail investor information processing.
Health product advisories issued in Canada: An assessment of public awareness, attitudes and use, and their impact on physician prescribing practice and patient safety

description: The research undertaken in this thesis was aimed at exploring the awareness and attitudes of both the Canadian public and health professionals regarding drug safety and their use of the various sources of drug risk information available in Canada. This information provides a deeper understanding of the strengths and weaknesses of the risk communication tools used by Health Canada, and serves as a starting point for improvements in the communication process. The results obtained in this research provide a baseline against which future improvements to the risk communication system can be compared, thereby allowing Health Canada to guide policy changes and program improvements based on empirical evidence. A series of case studies were examined in order to assess the impact that dear health professional letters issued in Canada had on the prescribing practice of physicians. Several studies of this nature have been conducted in the U.S., with most concluding that dear doctor letters do not have a significant impact on physician prescribing practice. The present examination of the impact that dear health professional letters have on prescribing practice in Canada is the first of its kind, and was needed in order to confirm or refute the findings of similar studies conducted elsewhere. This research is important from a population health perspective since any changes to Health Canada's risk communication policy that results in increased awareness, increased use, or increased confidence in the risk information provided by Health Canada will, in turn, result in more appropriate prescribing practice and improved patient safety. Given that the risks posed by drugs are known to be a significant cause of morbidity and mortality in developed countries and that Canadians consume a large number of drugs, it follows that interventions which successfully improve drug risk communication have the potential to improve individual patient safety as well as the overall health of Canadians.

description: This study was a prospective, parallel-group, randomized, double-blind, vehicle-controlled, multi-centre clinical trial to compare the efficacy of topical sertaconazole 2% cream with vehicle in reducing chronic pruritus in subjects with atopic dermatitis, and to assess its safety and local tolerability. A total of 70 subjects applied either of the 2 treatments twice daily for a period of 4 weeks on affected, itchy skin areas. Treatment efficacy was evaluated primarily considering the item itch intensity on a 5-point verbal rating scale. Insomnia, state of atopic dermatitis (Scoring Atopic Dermatitis; SCORAD), quality of life and therapy benefit were also assessed. No significant difference between active treatment and vehicle was found at any of the time-points for any of the investigated parameters. Under the experimental conditions of the study, sertaconazole 2% cream did not exert anti-pruritic effects that were better than vehicle in subjects with atopic dermatitis who had chronic pruritus.

description: Cette recherche démontrera que pour George Orwell, dans son roman Nineteen Eighty-Four, le pouvoir devenu une finalité ne peut mener qu'à un régime nihiliste. Dans le premier chapitre, il sera exposé que le pouvoir n'est plus contrôlé par une classe sociale: le pouvoir s'émancipe du contrôle humain. Une fois libéré, tout doit être détruit afin que rien ne menace la hiérarchie du pouvoir. C'est pour cette raison que le pouvoir dépossède l'homme de son identité et de sa conscience en lui imposant une surveillance constante et en créant une langue orthodoxe par laquelle il est impossible de penser contre le Parti. De plus, le Parti devra maintenir sa position de domination en figeant l'histoire. Il fait ceci par l'utilisation d'un ennemi intérieur, par une guerre permanente et par la réécriture de l'histoire. Pour bien comprendre la portée de tout ceci, il sera exposé dans le troisième chapitre que la quête du pouvoir absolu a lieu, selon Orwell, en raison de l'effritement de la religion et de l'effritement du patriotisme.

description: We present initial results from the low-latitude Galactic plane region of the High Time Resolution Universe pulsar survey conducted at the Parkes 64-m radio telescope. We discuss the computational challenges arising from the processing of the terabyte-sized survey data. Two new radio interference mitigation techniques are introduced, as well as a partially-coherent segmented acceleration search algorithm which aims to increase our chances of discovering highly-relativistic short-orbit binary systems, covering a parameter space including potential pulsar-black hole binaries. We show that under a constant acceleration approximation, a ratio of data length over orbital period of ~0.1 results in the highest effectiveness for this search algorithm. From the 50 per cent of data processed thus far, we have re-detected 435 previously known pulsars and discovered a further 60 pulsars, two of which are fast-spinning pulsars with periods less than 30ms. PSR J1101-6424 is a millisecond pulsar whose heavy white dwarf (WD) companion and short spin period of 5.1ms indicate a rare example of full-recycling via Case A Roche lobe overflow. PSR J1757-27 appears to be an isolated recycled pulsar with a relatively long spin period of 17ms. In addition, PSR J1244-6359 is a mildly-recycled binary system with a heavy WD companion, PSR J1755-25 has a significant orbital eccentricity of 0.09, and PSR J1759-24 is likely to be a long-orbit eclipsing binary with orbital period of the order of tens of years. Comparison of our newly-discovered pulsar sample to the known population suggests that they belong to an older population. Furthermore, we demonstrate that our current pulsar detection yield is as expected from population synthesis.

description: A new eusuchian from the early Paleocene Fort Union Formation of North Dakota is to be described based on a partial skull and jaws. The new form bears a striking outward resemblance to two ostensibly unrelated eusuchians: the basal crocodylian Borealosuchus sternbergii (late Maastrichtian, Montana) and the alligatoroid Diplocynodon remensis (late Paleocene, France) and preserves a confusing combination of plesiomorphic and derived states, calling into question the monophyly of Borealosuchus, as currently construed. In particular, the quadrate foramen aëreum of the Fort Union form is located on the dorsal rather than the dorsomedial surface of the quadrate ramus, suggesting an alligatoroid affinity. Maximum parsimony analyses recover trees supporting three distinct positions for the new form – within Diplocynodon, basal within Borealosuchus, or as an allodaposuchid. A re-evaluation of the morphology of early members of Borealosuchus from the Western Interior suggests they might be basal alligatoroids. However, later western forms (e.g. Borealosuchus wilsoni) and fossils referred to Borealosuchus from the Atlantic Coastal Plain (e.g. B. threeensis) may not actually fall within Borealosuchus and instead be eusuchians close to the ancestry of Crocodylia. A full reanalysis of species currently described as Borealosuchus is suggested. These results bear not only on our understanding of the morphology of the ancestral crocodylian, but also on the historical biogeography of early alligatoroids in North America and Asia.
Dual polarized sinuous antenna and ultra wideband feed design and integration

Subjects: subject: Engineering, Electronics and Electrical.

description: The designs of multi-arm planar sinuous antennas and their feeding networks are presented in this thesis for operation from 2-18GHz. The sinuous antenna's superior ultra wideband performance and dual polarization capability makes it ideal for both civil and military applications like direction-finding (DF) systems. The sinuous antennas generate broadside patterns with dual linear or circular polarization over wide beamwidths with good gain over the entire frequency band. The bandwidth of the sinuous antenna is virtually unlimited and is only restricted by the design of the feed network. There has been very little publicized research geared towards this antenna due to its complicated feed network design and integration. In this thesis novel feed designs are presented in the form of ultra wideband balun structures, symmetrical 3dB 90° directional couplers, and their integration into the system. In addition to the specific designs, modifications were made to the sinuous antenna, while new techniques were developed with concentration on theoretical and practical implementation to minimizing size, weight, and costs. The results presented for the performance of the sinuous antenna show improvements over existing designs.

In this thesis, we propose an ALOHA/Slotted-CSMA protocol for a very high-speed optical LAN interconnected by a passive star coupler. The network performance based on channel throughput and delay characteristics are analyzed and the numerical results are given. Comparisons are made with the other protocols based on the same network architecture. Detailed network modeling and modifications are given by using the software package BONeS (Block Oriented Network Simulator). A computer simulation program was developed to simulate the performance of the ALOHA/Slotted-CSMA protocol. Finally, results of the simulation and analytical studies are given and the comparisons and suggestions for future studies are made.

description: In programming languages, algebraic datatypes along with the associated features of pattern matching and recursion provide notational convenience for problem-solving. This convenience helps programmers abstract away from low-level details and focus on the problem at hand, thereby helping them avoid software bugs. Because of this expressivity, however, high-level programming languages with these features are complex software artifacts, and their implementations may have subtle and undesirable interactions. For general-purpose languages these interactions may result in unintuitive edge cases, run-time crashes, unintended non-termination, or unexpected behavior. For programming languages that serve also as interactive theorem provers (ITPs), the consequences of bugs in such systems may be as dire as losing trust in proofs carried out within them.
description: While many lines of evidence can increase trust in software, such as testing, the most robust is formal, machine-checked verification. Unfortunately, formal verification of a fully-fledged programming language is a Herculean task. To facilitate this endeavor, language designers can turn to elaboration, a term of art describing the type-guided translation of a language into a simpler kernel language. Such a translation can then be proven correct, with the kernel language being easier to test or formally verify.
description: This dissertation concerns the elaboration of inductive datatypes into the calculus of dependent lambda eliminations (CDLE), a dependent type theory designed to be both expressive and tiny. Unlike other type theories, which must bring datatypes and their associated induction principles into the kernel language, in CDLE it is possible to derive datatypes and their induction principles from a relatively small set of language features. This dissertation demonstrates how higher-level syntax for many desirable features --- inductive datatype declarations, pattern matching, recursion and induction with a form of typed-based termination checking --- can be soundly translated into CDLE.
L'inscription du littéraire dans Charles Guérin de Pierre-Joseph-Olivier Chauveau.

description: Comme plusieurs romans canadiens du XIX e siècle, C harles Guérin de Pierre-Joseph-Olivier Chauveau est souvent étudié par la critique littéraire pour son aspect didactique: rien d'étonnant à cela quand on sait que les romanciers canadiens du XIX e siècle niaient tout aspect romanesque à leurs récits sous l'influence d'un discours nationaliste et moralisateur exigeant qu'on réhabilite le genre romanesque--jugé immoral et frivole--à des fins de propagande. Même la préface de Charles Guérin se veut claire à ce sujet: c'est moins un «roman» qu'une dissertation politique et philosophique qu'écrit Chauveau en écrivant Charles Guérin . Or, quand on y regarde de près, ce discours de dénégation romanesque demeure ambigu et comporte des failles qui permettent de supposer que Charles Guérin appelle une lecture romanesque. La présente thèse entend le montrer en étudiant le discours ambiant sur la littérature au moment de l'énonciation de Charles Guérin et le discours paratextuel accompagnant ce texte, éléments qui viendront éclairer le discours que tient Charles Guérin lui-même sur la littérature--plus précisément sur le genre romanesque--à travers l'inscription du littéraire par le biais de l'intertextualité et de la reprise de formes littéraires types héritées du genre romanesque.

description: Organic farming is one of the fastest growing sectors of world agriculture. Although it represents only 1% of world agricultural area, organic is one of the most recognized food labels and most people in developed countries consume some amount of organic food today. There is a wide range of interpretations of what organic means by different actors in the sector. Here we examine eight different organic regulations from across the world to understand how they have codified the large diversity of ideas inherent in organic agriculture. Our analysis shows that organic practices and regulations do not differ substantially between countries – across the board organic regulations define organic mainly in terms of 'natural' vs. 'artificial' substances that are allowed (or not) as inputs. This interpretation of organic as “chemical-free” farming, largely void of broader environmental principles, does not fully incorporate the original ideas of organic theoreticians who conceived it as a holistic farming system aimed primarily at improving soil health, thereby leading to improved animal, human, and societal health. This narrow focus of organic regulations can be explained by the interest of organic consumers who predominantly buy organic because they believe it is healthier and more nutritious due to the absence of harmful substances. Organic regulations need to place more emphasis on environmental best practices in order to ensure that organic agriculture can contribute to sustainability objectives.

description: Background The roles of the neurotrophins NGF (Neurotrophic growth factor) and BDNF (brain-derived neurotrophic factor) in neuronal growth and development are already known. Meanwhile, the neurotrophin receptors TrkA (tropomyosin related kinase A), TrkB, and p75 are important for determining the fate of cells. In endometriosis, this complex system has not been fully elucidated yet. The aim of this study was to evaluate the expression and location of these neurotrophins and their receptors in peritoneal (PE) and deep infiltrating endometriotic (DIE) tissues and to measure and compare the density of nerve fibers in the disease subtypes. Methods PE lesions (n = 20) and DIE lesions (n = 22) were immunostained and analyzed on serial slides with anti-BDNF, −NGF, −TrkA, −TrkB, −p75,-protein gene product 9.5 (PGP9.5, intact nerve fibers) and -tyrosine hydroxylase (TH, sympathetic nerve fibers) antibodies. Result There was an equally high percentage (greater than 75 %) of BDNF-positive immunostaining cells in both PE and DIE. TrkB (major BDNF receptor) and p75 showed a higher percentage of immunostaining cells in DIE compared to in PE in stroma only (p

description: bare, witness is an interdisciplinary project that explores my identity as a biracial artist. Utilizing the transformative potential of my dancing body in African American social dances, hip-hop dance, and house dance, my research focuses on my spiritual experiences in American religious culture. Through rhythm and sustainability of repetitive movements, these elements create a meditative state that allows me to commune with my spiritual self, transcending my physical body and connecting with my ancestors and higher power. I seek this connection through African American social dances of the late 1970s through today that originated from enslaved African dances in the 19th century, such as the Juba, Buck, Wing, Cakewalk, and Jig, which have profoundly impacted the development of hip-hop dance and my personal embodied practices.I examine the role of digital media as a tool for capturing my inner emotions and spiritual self, manifested through projection. I create a clear narrative of my journey by using digital media and the mediated body in performance to direct the audience. Through this exploration in digital media, I aim to shed light on themes of resistance, joy, creativity, and identity that have always been present in African American social dances and hip-hop dance. This process brings me closer to my ancestors and heavenly father, furthering my research into American religious culture through hip-hop and house dance.

description: In this work, the process began by coating a layer of poly (butylene adipate-co-terephthalate) (PBAT)/poly (vinyl alcohol) (PVA) on the surface of magnetic Fe3O4 particles (MPs) obtained from the nickel slag. Then, it was grafted by glutaraldehyde (GA) to obtain Fe3O4@PBAT/PVA-g-GA MPs, which were used as a carrier. Finally, the immobilized PGA was achieved by forming a covalent bond through the Schiff base reaction. To confirm each stage, employed Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), vibration sample magnetometer (VSM), scanning electron microscope-energy spectroscopy of dispersive x-rays (SEM-EDS), inductively coupled plasma mass spectrometry (ICP-MS), and x-ray photoelectron spectrophotometry (XPS). The immobilization conditions were studied and optimized to improve immobilized PGA stability and catalytic activity. The immobilization of PGA demonstrated its optimal performance under the process conditions. The results were achieved using a 2.5 vol.% enzyme solution concentration, a pH of 8.0, an immobilization time of 24 h, and an immobilization temperature of 37 °C. Under these conditions, the immobilized PGA exhibited an enzyme activity recovery (EAR) of 93.71%, an enzyme activity (EA) of 31,367 U/g, and an enzyme loading capacity (ELC) of 111 mg/g. The operating stability, reusability, and storage stability of Fe3O4@PBAT/PVA-g-GA-PGA MPs were investigated. Comparatively, immobilized PGA exhibited superior operational and storage stability compared to free PGA. Even after 11 repeated uses, the immobilized PGA retained 58% of its initial activity, while the carrier recovery (Re) reached 82%. This indicated that the immobilized PGA MPs offer improved longevity and efficiency, making them a promising choice for practical applications.
