description: Crohn’s disease (CD) is a chronic, idiopathic and relapsing inflammatory disease of the gastrointestinal (GI) tract. Current theories point to an impaired immune response to microbes within the intestinal flora in a genetically susceptible host. Although the lymphatic obstruction represents one of the main histopathological diagnostic criteria, its etiology is unknown. Many animal models that, in some respects, resemble human CD have been developed, but these models do not represent the complexity of human disease. We planned to obtain an animal model of CD by surgical manipulation of the enteric lymphatic vessels in the TNBS model of rat ileitis. Surgical approach: 12 F344 male rats were surgically treated by ligature and cut of ileo-colic lymphatic chain near the Treitz. The lymph nodes near the ileocecal valve were injected with a sclerosing agent (control group). Surgical and chemical approach: F344 were treated as above and, at the same time, intraluminally ileum injected with TNBS, a chemical reagent able to induce severe enteritis. 6 rats were sacrificed after one week (group 1). 8 rats received two more weekly TNBS injections and then were sacrificed (group 2). Control and treated rats were sacrificed at the same time. Animals were weighted and monitored for clinical manifestations of GI inflammation. At sacrifice, macroscopical changes were noted and ileum and colon specimens were harvested and processed for histopathological analysis. Most of the animals showed adhesions of bowel loops and thickening of the mesentery. Groups 1 and 2: TNBS induced more severe macroscopical features of inflammation in the intestinal wall, such as fistolae, dilatation of the ileum and sometimes intestinal obstruction. Microscopically, we observed transmural inflammatory infiltrate, fibrosis of mesentery, granulomas, and in the most severe cases, signs of neoangiogenesis, derangement of the muscle layers, ulcers and loss of villi in the mucosa. Besides the microscopical inflammatory changes, we evidenced an increased number of dilated lymphatic vessels. Group 1: one week after a single injection, most of the animals partially solved and showed less severe microscopical damages. The surgical and chemical approach did not induce in this rat model the severe fibrosis and the stricture of intestinal lumen that usually lead to surgery in human CD. However, the histopathological features found in these rats resemble the severe pathological features observed in human CD.

description: The annihilation of dark matter particles captured by the Sun can lead to a neutrino flux observable in neutrino detectors. Considering the fact that these dark matter particles are non-relativistic, if a pair of dark matter annihilates to a neutrino pair, the spectrum of neutrinos will be monochromatic. We show that in this case, even after averaging over production point inside the Sun, the oscillatory terms of the oscillation probability do not average to zero. This leads to interesting observable features in the annual variation of the number of muon track events. We show that smearing of the spectrum due to thermal distribution of dark matter inside the Sun is too small to wash out this variation. We point out the possibility of studying the initial flavor composition of neutrinos produced by the annihilation of dark matter particles via measuring the annual variation of the number of muon-track events in neutrino telescopes.

title: Teachers’ Learning of Fraction Division With Area Models
Creators: name: Leitch, Michael
Publisher: name: Utah State University
Year: 2023

description: Research shows that fractions concepts play an essential role in the learning of later mathematics. However, fractions are notoriously difficult to learn and difficult to teach. Division with fractions is a frequent subject in mathematics education research because division is the most conceptually difficult of the four basic arithmetic operations and rational numbers are the most conceptually difficult numbers in K-12 mathematics curricula.
In the U.S., teachers are generally proficient with mathematical procedures, but often have difficulty explaining the concepts underlying the procedures. Research indicates a positive association between student learning and teachers’ depth of conceptual understanding of mathematics. Thus, it is important to ensure that future and practicing teachers are competent with fractions operations at a deep, conceptual level.
In order to gain a better understanding of teachers’ conceptions of division with fractions, this study engaged teachers in a 4-hour professional development program designed to deepen the teachers’ understanding of fractions and their ability to represent fraction operations through the construction of rectangular area models. Eight teachers were given one-to-one professional development. Analysis of these videos showed that teachers constructed idiosyncratic conceptions yet faced some common challenges. One common challenge was that a central part of the division concept was readily visible to the teachers in some contexts but not in other contexts. Another common difficulty teachers experienced was conceptually explaining why the quotient to a fraction division problem should be based on a whole unit of the divisor.
Additionally, teachers constructed different modules of division arising from the structure of the situation in which the division was conceptualized. Models of partitive division with one apparent referent were easier to conceptualize and represent. Models of partitive division with two apparent referents were more difficult to conceptualize and represent. Two-referent models of partitive division with fractions are fundamental to rate and intensive quantity, and directly relate to other topics in mathematics, such as proportion and derivatives. Results of this study shed light on potentially common conceptual difficulties as well as suggest ways that learners can facilitate a conceptual understanding and representational fluency with fractions division.

description: Epidemiological data consistently demonstrate a reduced cancer risk associated with a polyphenols rich diet. Hibiscus sabdarifa (HS), a polyphenols rich plant widely consumed worldwide as beverage and used in folk medicine, has recently gained interest thanks to its antioxidant, anti-inflammatory and chemopreventive properties. In the present study we investigated the antitumoral potential of HS extract in two different human tumor cell lines: Multiple Myeloma cells (RPMI 8226) and Oral Squamous Cell Carcinoma cells (SCC-25). MTT assays showed that HS extract induced a dose-dependent viability reduction in both the cells lines. For the subsequent experiments we used HS at the concentration of 5 mg/ml that was the most effective in inducing cell viability reduction after 48h of treatment. Viable cell count using trypan blue staining demonstrated that the HS extract induced decrease in cell growth of both the cell lines and this was due to a reversible cytostatic rather than a cytotoxic effect. Wound-healing and cell invasion assays, respectively performed by a scratch of cell monolayer and Boyden Chamber transwell test, demonstrated that HS extract was able to reduce motility and invasiveness in both RPMI 8226 and SCC-25 cells. The chemical inhibition of ERK1/ERK2 and PI3K, with U0126 and wortmannin respectively, reduces proliferation and migration of both SSC-25 and RPMI cells and HB extract treatment played an additive action with the inhibitors. In conclusion, our results suggest that HS extract have antitumoral properties, since it proved to inhibit tumoral cell growth and cell migration and invasiveness. It is interesting to note that HS extract is effective against two very different tumor cell lines. In fact, RPMI 8226 cells are of hematopoietic origin and grow in suspension, whereas SCC-25 cells derive from epithelium and are characterized by adherent cell growth. Therefore, although further studies are needed to clarify the molecular mechanisms involved in its action, we proposed HS as a potential chemopreventive agent.

title: Discharge Coefficients of Oblique Weirs

Publisher: name: Utah State University

description: Oblique weirs are those weirs placed at an angle with respect to the channel centerline. They can be used in canal applications where more discharge is needed, but there is limited freeboard. The discharge coefficients were determined for 54 different weirs by measuring total head for various flows over each weir. These weirs included sharp, half round and quarter-round-crested weirs. There were 18 weirs for each crest shape with three weir heights for each angle tested. The oblique angles tested were 10°, 15°, 25°, 45°, 60°, and 90° with respect to the channel centerline, with the nominal weir heights being 4, 8, and 12 inches. The half-round-crested weirs were the most efficient, followed by the quarter-round-crested weirs and the sharp-crested weirs were the least efficient. By decreasing the oblique angle, the weir length became longer and the weir would be more efficient than the normal weir.

description: It is well known that reflection of a Gaussian light beam ($\text{TEM}_{00}$) by a planar dielectric interface leads to four beam shifts when compared to the geometrical-optics prediction. These are the spatial Goos-Hänchen (GH) shift, the angular GH shift, the spatial Imbert-Fedorov (IF) shift and the angular IF shift. We report here, theoretically and experimentally, that endowing the beam with Orbital Angular Momentum (OAM) leads to coupling of these four shifts; this is described by a $4 \times 4$ mixing matrix.

description: Medical students preparing to undertake general practice (GP) placements need to be equipped with the unique skills required to successfully utilise and adapt to current and emerging remote consultation modalities used in primary care and integrate this into their day-to-day clinical practice. Medical educators needed to flexibly and quickly cater learning to the evolving landscape. A three-hour teaching session was devised to be delivered to 50 students online via Microsoft Teams™ and facilitated by five general practice tutors in groups of 10, prior to students’ GP placements. In pre-assigned pairs, students undertook two role-play scenarios for the main remote modalities of telephone and video-consultations. E-consultations were explored via discussion of simulated encounters. The authentic technology pertinent to each modality was used; this included a training version of NHS Scotland’s Near Me IT platform for video-consultations, the students’ own mobile phones for telephone consultations and simulated PDFs generated using the e-consultation facility. Teaching was evaluated via a student focus group pre and post placement. Student feedback was positive. The session prepared them for their placement and increased their confidence. They suggested this teaching be incorporated earlier in the medical school curriculum. They appreciated learning with the same IT platforms used on placement. Some students had no prior experience of remote consultations and subsequently were expected to undertake independent remote consultations almost immediately upon arrival. Careful design of challenging scenarios mirroring common GP presentations via remote modalities can increase student preparedness and confidence prior to GP placements during the COVID-19 pandemic.

description: Rabbits with high fat diet (HFD)-induced metabolic syndrome (MetS) developed hypogonadotropic hypogonadism (HH) and showed a reduced gonadotropin-releasing hormone (GnRH) immunopositivity in the hypothalamus (Filippi et al., 2009). This study investigated the relationship between MetS and hypothalamic alterations in HFD-rabbits. Gonadotropins levels decreased as a function of MetS severity, glucose intolerance, hypothalamic gene expression of glucose transporter 4 (GLUT4) and interleukin-6 (IL-6). HFD significantly induced mRNA expression and hypothalamic immunopositivity of GLUT4 and IL-6, as well as a low-grade hypothalamic inflammation (microglial activation with unchanged astroglia morphology), while reduced hypothalamic immunopositivity for KiSS-1 receptor (KiSS-1R), whose mRNA expression negatively correlated with glucose intolerance. Moreover, high glucose exposure down-regulated KiSS-1/KiSS-1R system and GnRH expression in human GnRH-secreting neuroblasts. A subset of HFD rabbits was treated with the farnesoid-X receptor agonist obeticholic acid, able to ameliorate glucose metabolism (Morelli et al., 2012). This treatment significantly increased GnRH mRNA and reduced GLUT4 and IL-6 immunopositivity. Our results suggest that HFD-induced glucose dysregulation negatively affects GnRH neuron function through an inflammatory injury at the hypothalamic level.

description: Using dimensional regularization, we compute the one-loop quantum and thermal corrections to the profile of the bosonic 1+1-dimensional phi^4 kink, the sine-Gordon kink and the CP^1 kink, and higher-dimensional phi^4 kink domain walls. Starting from the Heisenberg field equation in the presence of the nontrivial kink background we derive analytically results for the temperature-dependent mean field which display the onset of the melting of kinks as the system is heated towards a symmetry restoring phase transition. The result is shown to simplify significantly when expressed in terms of a self-consistently defined thermal screening mass. In the case of domain walls, we find infrared singularities in the kink profile, which corresponds to interface roughening depending on the system size. Finally we calculate the energy density profile of phi^4 kink domain walls and find that in contrast to the total surface tension the local distribution requires composite operator renormalization in 3+1 dimensions.

description: The Recorded Consultation Assessment (RCA) was rapidly developed to replace the Clinical Skills Assessment (CSA) for UK general practice licencing during COVID-19. We aimed to evaluate candidate perceptions of the RCA and relationships with performance. We conducted a cross-sectional survey of RCA candidates with attitudinal, demographic, and free text response options, undertaking descriptive and factor analysis of quantitative data with qualitative thematic analysis of free text. Binomial regression was used to estimate associations between RCA pass, candidate characteristics and questionnaire responses. 645 of 1551 (41.6%) candidates completed a questionnaire; 364 (56.4%) responders permitted linkage with performance and demographic data. Responders and non-responders were similar in exam performance, gender and declared disability but were significantly more likely to be UK graduates (UKG) or white compared with international medical (IMG) or ethnic minority graduates. Responders were positive about the digital platform and support resources. A small overall majority regarded the RCA as a fair assessment; a larger majority reported difficulty collecting, selecting, and submitting cases or felt rushed during recording. Logistic regression showed that ethnicity (white vs minority ethnic: odds ratio [OR] 2.99,95% confidence interval [CI] 1.23, 7.30, p = 0.016), training (UK vs IMG: OR 6.88, 95% CI 2.79, 16.95, p

description: In this book, the authors introduce the notion of set codes, set bicodes and set n-codes. These are the most generalized notions of semigroup n-codes and group n-codes. Several types of set n-codes are defined. Several examples are given to enable the reader to understand the concept. These new classes of codes will find applications in cryptography, computer networking (where fragmenting of codes is to be carried out) and data storage (where confidentiality is to be maintained). We also describe the error detection and error correction of these codes. The authors feel that these codes would be appropriate to the computer dominated world. This book has three chapters. Chapter One gives basic concepts to make the book a self-contained one. In Chapter Two, the notion of set codes is introduced. The set bicodes and their generalization to set n-codes (n >= 3) is carried out in Chapter Three. This chapter also gives the applications of these codes in the above-mentioned fields.

description: Over 46 million people live with dementia globally, a number expected to triple by 2050 (Mukadam et al, 2019). Dementia has a significant negative impact on memory and, in turn, the sense of self (Jetten et al, 2010). It has been reported that one of the most distressing symptoms of dementia is a feeling of identity loss associated with gaps in autobiographical self-knowledge (Addis & Tippett, 2004). The human experience of ‘selfhood’ is conceptualised in this review as the knowledge of having a unique identity and physical presence in the world, accompanied by a strong sense of continuity overtime (Ross et al., 2011). However, selfhood is a multidimensional and complex concept. The existing literature on the impact of dementia on selfhood consists of distinct studies employing diverse methods as well as often focusing on individual manifestations of the psychological self. Thus, it is currently not known what the nature and scope of the available evidence is on the potential changes in selfhood in people living with dementia. For the purpose of the current scoping review, only the cognitive aspects of self will be considered as social constructions of the self are beyond our objectives; consequently, the term psychological self will be used. Recognising the multidimensional nature of the psychological self, the current scoping review aims to explore the impact of dementia on selfhood.

Navier-Stokes hydrodynamics of thermal collapse in a freely cooling granular gas

description: We employ Navier-Stokes granular hydrodynamics to investigate the long-time behavior of clustering instability in a freely cooling dilute granular gas in two dimensions. We find that, in circular containers, the homogeneous cooling state (HCS) of the gas loses its stability via a sub-critical pitchfork bifurcation. There are no time-independent solutions for the gas density in the supercritical region, and we present analytical and numerical evidence that the gas develops thermal collapse unarrested by heat diffusion. To get more insight, we switch to a simpler geometry of a narrow-sector-shaped container. Here the HCS loses its stability via a transcritical bifurcation. For some initial conditions a time-independent inhomogeneous density profile sets in, qualitatively similar to that previously found in a narrow-channel geometry. For other initial conditions, however, the dilute gas develops thermal collapse unarrested by heat diffusion. We determine the dynamic scalings of the flow close to collapse analytically and verify them in hydrodynamic simulations. The results of this work imply that, in dimension higher than one, Navier-Stokes hydrodynamics of a dilute granular gas is prone to finite-time density blowups. This provides a natural explanation to the formation of densely packed clusters of particles in a variety of initially dilute granular flows.

description: Tracer mass fraction as a function of the fractional mass discharged from silo step-change experiments. In each plot the monodisperse tracer is quantified by the colour (a layer of blue tracer particles sit above a layer of yellow ones), while in the bidisperse case the tracer is quantified by particle size. The left plot shows the discharge of a monodisperse and bidisperse mixtures in a silo with no insert. The right plot is the same as the left except that there is a flow-correcting insert placed in the silo.
The inert doublet model of dark matter revisited

description: The inert doublet model, a minimal extension of the Standard Model by a second higgs doublet with no direct couplings to quarks or leptons, is one of the simplest scenarios that can explain the dark matter. In this paper, we study in detail the impact of dark matter annihilation into three-body final state on the phenomenology of the inert doublet model. We find that this new annihilation mode dominates, in a relevant portion of the parameter space, over those into two-body final states considered in previous analysis. As a result, the computation of the relic density is modified and the viable regions of the model are displaced. After obtaining the genuine viable regions for different sets of parameters, we compute the direct detection cross section of inert higgs dark matter and find it to be up to two orders of magnitude smaller than what is obtained for two-body final states only. Other implications of these results, including the modification to the decay width of the higgs and to the indirect detection signatures of inert higgs dark matter, are also briefly considered. We demonstrate, therefore, that the annihilation into three-body final state can not be neglected, as it has a important impact on the entire phenomenology of the inert doublet model.

description: The measurement of a quantitative and macroscopic parameter to estimate the global motility of a large population of swimming biological cells is a challenge Experiments on the rheology of active suspensions have been performed. Effective viscosity of sheared suspensions of live unicellular motile micro-algae (\textit{Chlamydomonas Reinhardtii}) is far greater than for suspensions containing the same volume fraction of dead cells and suspensions show shear thinning behaviour. We relate these macroscopic measurements to the orientation of individual swimming cells under flow and discuss our results in the light of several existing models.
title: Evaluation of Levulinic Acid for Topical Decontamination of Meat Surfaces
Creators: name: Smith, Jeffrey V.
Publisher: name: Utah State University
Year: 2011

description: Experiments were performed to investigate the effects of wash treatments, consisting of hot water, 2% lactic, 2% acetic, or 2% levulinic acid, for decontamination of pathogenic bacteria previously inoculated onto meat surfaces, to inhibit growth of pathogenic bacteria inoculated onto previously washed meat surfaces, and on the organoleptic quality of sliced turkey roll and beef trim. Acid washes were no more effective at reducing Escherichia coli O157:H7 on beef plate, Listeria monocytogenes on sliced turkey roll, and Salmonella on pork belly than was water wash. Only lactic acid treatment was more effective than water at reducing Salmonella on chicken skin, but by less than 1 log CFU/cm2. Increasing wash temperatures with 2% levulinic acid did not reduce E. coli O157:H7 on beef plate. Organic acid washes did not protect against growth of L. monocytogenes and E. coli O157:H7. Acetic acid prevented growth of Salmonella, but only on chicken skin. Organic acid spray treatments of sliced turkey roll and beef trim did not affect consumer liking of turkey roll or cooked ground beef patties. Acid treatments had some effect on instrumental color measurements, but these appear to have little practical significance. Overall, washing with 2% organic acid solutions was no more effective at reducing pathogenic bacteria on meat surfaces than washing with water.
Decaying Dark Matter in Light of the PAMELA and Fermi LAT Data

description: A series of experiments measuring high-energy cosmic rays have recently reported strong indications for the existence of an excess of high-energy electrons and positrons. If interpreted in terms of the decay of dark matter particles, the PAMELA measurements of the positron fraction and the Fermi LAT measurements of the total electron-plus-positron flux restrict the possible decaying dark matter scenarios to a few cases. Analyzing different decay channels in a model-independent manner, and adopting a conventional diffusive reacceleration model for the background fluxes of electrons and positrons, we identify some promising scenarios of dark matter decay and calculate the predictions for the diffuse extragalactic gamma-ray flux, including the contributions from inverse Compton scattering with the interstellar radiation field.

description: This master's thesis investigates the effects on the medium voltage circuit breaker on the supply side by certain power electronic converters. In particular, the case of a variable frequency drive powering an induction motor is considered and the effect of this converter on the circuit breaker parameters are observed and analyzed. Since,powerelectronicconvertersdonotfollowthenormsofconventionalloads,they have highly variable and different characteristics and therefore their influence on the supplyvoltageandcurrentarealsounconventional.Thevariablefrequencydriveunder consideration is a combination of a rectifier and an inverter which uses an open loop pulse width modulation (PWM) scheme which are coupled together by means of a series inductance and DC link capacitance. Also, analysis is made as to which component within the converter influences the supply parameters and how their variations influences the supply. Investigations and simulations are carried out by means of the PSIM software. Therefore, this thesis investigates the possibilities of adverse effects the converter has on the circuit breaker performance and attempts to provide some recommendations to mitigate these effects.
