Effect of aperture geometry on the steady flow through the narrow apertures in a pulp screen : numerical and experimental study
Creators: name: Mokamati, Satyanarayana V.
Publisher: name: University of British Columbia
Year: 2011

description: This investigation examines turbulent flow across a contoured wall with evenly-spaced slots and a series of flow bifurcations, as found in industrial pulp screening. The contoured wall and slotted apertures are formed from an array of 'wires', with cross-sectional geometry characterized by contour height and wire width. Four complementary studies were conducted to examine the velocity and turbulence characteristics of this complex flow. In the first study, a Computational Fluid Dynamics (CFD) model was developed to theoretically examine the effect of wire cross-sectional geometry on the flow field. The model shows that separation of the viscous layer occurs upstream of the aperture, and a vortex occupies the slot entry. As contour height increased, turbulence intensity near the wall increased. Further, turbulence intensity near the wall increased with decreasing wire width. It was shown that the ratio of contour height to wire width controls the boundary layer thickness and turbulence intensity near the wall. In the second study, the velocity field near the slot entry was experimentally measured using Particle Image Velocimetry (PIV) and was compared with theoretical predictions. In general, the vortex size and shape were similar to that predicted by CFD. In the third study, the velocity and turbulence intensity distributions above the wall were experimentally measured using Laser Doppler Velocimetry (LDV). The velocity near the wall was shown to decrease with contour height and increase with wire width. Further, the velocity near the wall was shown to increase as the flow through the slots increased. A correlation for velocity above the wall was determined as a function of the ratio of contour height to wire width, upstream velocity and flow through the slotted apertures. The correlation can be used to estimate shear stress at the wall. The maximum turbulence intensity near the wall was shown to increase with contour height and decrease with wire width. In the fourth study, the motion of 2 mm long nylon fibres moving near the apertures was experimentally observed using High-speed Video (HSV). Fibres were shown to interact with both the wires and the vortices during passage. It was observed that fibres only passed through the slots after impacting the wire and being pulled back into the slot by the vortex. Further, fibres were shown to pass through the slots with high contour wires more readily.

description: We study theoretically many-body properties of magic-angle twisted bilayer graphene for different doping levels. Our investigation is focused on the emergence, stability, and manifestations of nematicity of the ordered low-temperature electronic state. It is known that, at vanishing interactions, the low-energy spectrum of the system studied consists of four almost-flat almost-degenerate bands. Electron-electron repulsion lifts this degeneracy. To account for such an interaction effect, a numerical mean-field theory is used. Assuming that the ground state has spin-density-wave-like order, we introduce a multicomponent order parameter describing spin magnetization. Our simulations show that the order parameter structure depends on the doping level. In particular, doping away from the charge neutrality point reduces the rotational symmetry of the ordered state, indicating the appearance of an electron nematic state. Manifestations of the nematicity can be observed in the spatial distribution of the spin magnetization within a moir{é} cell, as well as in the single-electron band structure. The nematicity is strongest at half-filling (two extra electron or holes per supercell). We argue that nematic symmetry breaking is a robust feature of the system ground state, stable against model parameters variations. Specifically, it is shown that, away from the charge neutrality point, it persists for all three parametrizations of the interlayer hopping amplitudes discussed in the paper. Obtained theoretical results are consistent with the available experimental data.

description: Nanofluids hold promise for a wide range of areas of industry. However, understanding of wetting behavior and deposition formation in course of drying and spreading of nanofluids, particularly containing surfactants, is still poor. In this paper, the evaporation dynamics of quantum dot-based nanofluids and evaporation-driven self-assembly in nanocolloidal suspensions on hexamethyldisilazane-, polystyrene-, and polypropylene-coated hydrophobic surfaces have been studied experimentally. Moreover, for the very first time, we make a step to understanding of wetting dynamics of superspreader surfactant-laden nanofluids. It was revealed that drying of surfactant-free quantum dot nanofluids in contrast to pure liquids undergoes not three but four evaporation modes including last additional pinning mode when contact angle decreases whilst triple contact line is pinned by the nanocrystals. In contrast to previous studies, it was found out that addition of nanoparticles to aqueous surfactant solutions leads to deterioration of spreading rate and to formation of double coffee ring. For all surfaces examined, superspreading in presence and absence of quantum dot nanoparticles takes place. Despite the formation of coffee rings on all substrates, they have different morphology. Particularly, the knot-like structures are incorporated into the ring on hexamethyldisilazane- and polystyrene-coated surfaces

title: The effect of ocean acidification on plant-animal interactions in a Posidonia oceanica meadow
Creators: name: Garrard, Samantha Laird
Publisher: name: The Open University
Year: 2013

description: Ocean acidification may be one of the greatest challenges facing 'Society over the next SO- 100 years. In the Mediterranean Sea, meadows of the seagrass Posidonia oceanica play a pivotal role in coastal systems, providing shelter and food for a highly diversified plant and animal community, and nursery for several commercial species of fish and bivalves. This thesis aims to provide a broad overview of the effect of acidification on P. oceanica, and its associated community, through observation of seagrass meadows associated with subtidal CO2 vents off the Castello Aragonese, Ischia, Italy. Control (mean pH 8.1) and acidified (mean pH 7.8) stations were situated in seagrass meadows on both the north and south side of the Castello Aragonese. Research was concentrated into three main objectives; to investigate the effect of acidification on 1) plant structure and function, 2) invertebrate community dynamics, and 3) macroherbivore grazing pressure. Results suggested that P. oceanica and its associated community should be robust to levels of acidification projected for the end of this century. Seagrass density, invertebrate abundance, and P. oceanica grazing pressure all increased in response to acidification. Although a slight decrease in invertebrate diversity was observed in 'acidified stations, species richness was maintained. Increased grazing by the fish Salpa salpa was most highly correlated to a decrease in epiphytic algal cover and C:N content of the [eaves, and an increase seagrass density. Whilst fish may select leaves with low algal cover and C:N content, previous research suggests that increased shoot density is a response to high grazing pressure. The abundance of many groups of invertebrate taxa was positively correlated to shoot density, whilst decapods decreased during months of reduced canopy height, suggesting changes in P. oceanica condition variables, in response to acidification, may lead to a cascade of indirect effects which have positive or negative influences on the abundance of the associated invertebrate community. One of the most striking findings of this thesis was the ability of calcifying species to persevere, and even flourish in acidified conditions. This may be due to the complex nature of the seagrass, and high levels of photosynthesis, leading to local maintenance of pH microclimates. Secondly, the high degree of pH variability that naturally occurs in these shallow water habitats may result in organisms that are be better equipped to withstand pH variation. This research suggests that highly productive, non-calcifying, biogenic habitats, such as seagrass beds, may provide a refuge from OA, and highlights the importance of their conservation.

Subjects: subject: French money market, Treasury, rediscount companies, open-market policy, discount rate
subject: E40, E42, E52

description: The article describes the features and operating techniques of the French money market. The author briefly recalls the events which led to the transformation of the old “marché hors banque” into the present “marché monétaire”, in which the dominant role is played by Treasury paper; and he refers to the measures adopted in 1926, the coming into existence around 1930 of the first rediscount companies, the introduction in 1938 of open-market policy, and the post-war innovations. There follows an account of the structure and modus operandi of the so-called “money market” in France under present conditions. Attention is drawn in particular to the special circumstances which, in contradiction to the logic of the system, have led to the maintenance, for many years, of “money market” rates which are above the official rate of discount.

description: Today's world is organized based on merit and value. A single global currency that's decentralized is needed for a global economy. Bitcoin is a partial solution to this need, however it suffers from scalability problems which prevent it from being mass-adopted. Also, the deflationary nature of bitcoin motivates people to hoard and speculate on them instead of using them for day to day transactions. We propose a scalable, decentralized cryptocurrency that is based on Proof of Work. The solution involves having parallel chains in a closed network using a mechanism which rewards miners proportional to their effort in maintaining the network. The proposed design introduces a novel approach for solving the scalability problem in the blockchain network based on merged mining.

Flavor Mass and Mixing and S_3 Symmetry -- An S_3 Invariant Model Reasonable to All --

Year: 2005
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We assume that weak bases of flavors (u, c)_{L,R}, (d,s)_{L,R}, (e, μ) _{L,R}, (ν_e, ν_μ)_{L,R} are the S_3 doublet and t_{L,R}, b_{L,R}, τ_{L,R}, {ν_τ}_{L,R} are the S_3 singlet and further there are S_3 doublet Higgs (H_D^1, H_D^2) and S_3 singlet Higgs H_S. We suggest an S_3 invariant Yukawa interaction, in which masses caused from the interaction of S_3 singlet flavors and Higgs is very large and masses caused from interactions of S_3 doublet flavors and Higgs are very small, and the vacuum expectation value _0 is rather small compared to the _0. In this model, we can explain the quark sector mass hierarchy, flavor mixing V_{CKM} and measure of CP violation naturally. The leptonic sector mass hierarchy and flavor mixing described by V_{MNS} having one-maximal and one-large mixing character can also be explained naturally with no other symmetry restriction. In our model, an origin of Cabibbo angle is the ratio λ=_0 /_0 and an origin of CP violation is the phase of H_D^1.

Structural changes in German bank balance sheets

Subjects: subject: Germany, banks, balance sheet structure, monetary reform, post-war developments, credit control, Central Bank
subject: E52, E58, G21

description: The article reviews the most significant shifts which have occurred in the balance sheet structure of banks in Germany under the influence of the Second World War and of the monetary reform of 1948. The author places the primary emphasis on what he considers to be the most substantial change caused by the reform: the almost complete destruction of the banks’ capital and reserves, and the measures taken by the authorities towards facilitating their reconstruction. It is noted that the results thus far achieved are appreciable, but that the situation can still not be said to be a normal one, especially since the exceptionally rapid growth of deposits has helped keep the ratio of the banks’ own resources to their borrowed funds low. The author goes on to provide analysis of other banking developments in postwar Germany which also reflect the exceptional vicissitudes undergone by the economy. The closing section then provides a short review of the measures of credit control which the Central Bank first adopted in 1951 and which it later tightened. JEL: E52, E58, G21

description: We resum to next-to-leading order the distribution in the ratio of the invariant hadron mass mX to the total hadron energy EX and the distribution in mX in the semileptonic decays B -> Xu l nu. By expanding our formulas, we obtain the coefficients of all the infrared logarithms at O(alphaS^2) and of the leading ones at O(alphaS^3). We explicitly show that the relation between these semileptonic spectra and the photon spectrum in the radiative decay B -> Xs gamma is not a purely short-distance one. There are long-distance effects in the semileptonic spectra which are not completely factorized by the structure function as measured in the radiative decay and have to be modelled in some way.

description: In Italy the national income statistics do not provide the elements allowing for a division of the total income between regions and provinces. The present article attempts to estimate the distribution by areas through calculations based on a group of indices which, taken together, might be regarded as sufficiently indicative of the regional and provincial product. The article falls into two parts: (a) regional distribution of national income and of its principal components, and movement of regional income from 1938 to 1953 and 1954; (b) regional analysis of selected consumptions other than food, and of figures for bank and postal savings deposits. The statistical technique used in dividing up the total income between provinces and regions is summarised in a short methodological appendix. As the author warns, the results obtained are only very rough estimates. Nonetheless, they offer the first statistical basis to evaluate the diverse economic levels in the geographical areas of Italy. JEL: E01, E24, E25

Effect of Laban Movement on gesture recognition and response of seventh- and eighth-grade band students
Creators: name: Udell, Ashlen Sprague
Publisher: name: No Publisher Supplied
Year: 2025

description: Multiple movement methods have been used in the music classroom for educational and research purposes. Laban Movement Analysis (LMA) is a movement framework that has been used with conductors, but there is limited research using Laban movements with K–12 band ensemble students. The purpose of this study was to investigate the effect of Laban instruction on the recognition and performance response to movement gestures among seventh- and eighth-grade band students (N = 44). I used a quantitative one-group pretest posttest design with Laban movement sessions as the treatment. The study took place during normal class time in the Fall of 2023 at a mid-Atlantic region public school. Data collected included an eight-question written assessment administered to all subjects in a group setting, an individual performance test completed one-on-one, and a group ensemble performance test administered to all subjects in a group setting. Each assessment was analyzed using a paired samples t-test to compare paired sample differences between pretest and posttest scores. The results of this study indicated significant effects of Laban movement instruction on middle school instrumentalists’ gesture recognition, particularly evident in total scores in the written assessment (p = .016), individual performance assessment (p < .001), and group ensemble performance assessment (p = .001). The findings suggest that middle school students can recognize Laban movements when used by a conductor and respond appropriately to the gestures on their instruments. Given this study’s findings, ensemble music educators, conductors, and preservice music teachers may find value in training with Laban Efforts, as this approach could support the development of ensemble performance skills and deepen students’ comprehension of conducting gestures.
Clinically relevant mechanisms of spinal cord injury : contusion, dislocation, and distraction
Creators: name: Choo, Anthony Min-Te
Publisher: name: University of British Columbia
Year: 2011

description: There remains no cure for traumatic spinal cord injury (SCI). Pre-clinical research typically models spinal cord transection, contusion, and compression, although in humans, other injury mechanisms such cord shearing from vertebral dislocation, and stretching from distraction occur frequently. This creates a potentially important disparity between experimental paradigms and clinical injuries. The objective of this thesis was to develop and compare three biomechanically distinct, yet clinically relevant SCI animal models. A multi-mechanism SCI system was developed to deliver high-speed (~100cm/s) injuries along any direction vector. A new vertebral clamping strategy with enhanced clamping strength (64.7±10.2N) and stiffness (83.6±18.9N/mm) was designed for modelling cervical vertebral dislocation (2.Smm), distraction (4.1mm), as well as contusion (1.1mm) injuries. The pattern of primary mechanical injury (n=36 rats) was found to differ between the three injury models. Contusion and dislocation produced intramedullary hemorrhage whereas overt vascular damage was not detected following distraction injury. Vertebral dislocation consistently sheared axons in the lateral columns. Plasma membrane disruption was detected by assessing the intracellular penetration of 10kDa dextran. Following contusion, membrane compromise of neuronal somata and axons was localized near the lesion epicentre whereas following dislocation and distraction, membrane damage extended several vertebral segments rostrally. At 3 hours post-trauma (n= 39 rats), damaged cell membranes were found to reseal especially in the white matter. In spite of this recovery, extensive loss of neurofilaments and accumulation of β-amyloid precursor protein was observed following dislocation injury. In the gray matter, staining for cytochrome c and the oxidative stress marker 3-nitrotyrosine was similar following contusion and dislocation but less pronounced after distraction. Reactive astrocytes and activated microglia extended over a greater rostro-caudal zone only in the dislocation model. These rostro-caudal patterns demarcate disparate populations of primary and secondary injury suggesting that therapies developed in contusion paradigms may not translate to other SCIs. Neuroprotection and repair strategies might favour contusion and distraction injuries, whereas axonal regeneration across a lengthy lesion may inevitably be required for restoring function following dislocation. This interaction between the primary mechanism of injury and secondary neuropathology suggests treatment paradigms may be guided in a mechanism-specific manner.

description: Akwa Ibom State of Nigeria is homogenous in terms of language with Ibibio as the main indigenous language. Yet, there are dialectal groups such as Annang, Oron, Andoni, Ibeno,

Eket, Okobo, Mbo, Iwerre and Efik. Therefore, this study set out to ascertain the extent that the Radio and the Television Services of the Akwa Ibom Broadcasting Corporation (AKBC), established, owned and operated by the Akwa Ibom State Government, have fulfilled their mandate of promoting and sustaining the culture of the State through the broadcast of programmes in the languages used in different parts of the State. The study content analysed the programmes of Radio Akwa Ibom (90.50 MHz FM band) and AKBC-TV Channel 45, Uyo (UHF band) from January 2017 to September 2018. The findings indicated that the amount of airtime given by the two stations to programmes in the different dialects spoken in Akwa Ibom State was one-third of the total airtime allotted to programmes in local languages; the remaining two-thirds were in Ibibio - the dominant local language. From the findings, it was concluded that although there was language diversity and inclusion in programme contents of Radio Akwa Ibom and AKBC-TV Channel 45, the diversity and inclusion was peripheral and skin-deep. It was recommended that AKBC as a Corporation should consciously pursue inclusion through diversity as part of its social responsibility by encouraging the production of programmes in other dialects spoken in the State but not yet covered in its programming.

La sua unità geografica è sempre stata considerata tale sin dall’antichità. Ha assunto i lineamenti attuali sin dall’Oligocene, quando è iniziato il corrugamento alpino. È un solco tettonico tra i più antichi che caratterizzano l’attuale superficie terrestre.

title: Functional studies of Ci-Gsx gene in the developing central nervous system of Ciona intestinalis
Creators: name: Esposito, Rosaria
Publisher: name: The Open University

description: Gsx genes encode for members of ParaHox family of transcription factor and are highly conserved throughout the animal kingdom. They are expressed mainly in the developing CNS in members of all major groups of metazoans. Gsx function, in the few organisms in which it has been investigated, is related re the specification of neural progenitors and in the regulation of the dorso-ventral patterning of the vertebrate neural rube. In the ascidian Ciona inlesrinalis, the model organism used in this work, a single Gsx ortholog has been identified, named Ci-gsx, whose zygotic expression is localized in the developing CNS, including the precursors of the ocellus photoreceptor cells. Clana ocellus, a pigmented multicellular photoreceptive organ, despite its simplicity, possesses functional and molecular similarities to vertebrate eye, thus representing a valuable tool to study the basic mechanisms of eye development. The aim of my PhD work has been the investigation of Ci-gsx function in the early specification of photoreceptor cells in Ciona intestinalis. To this end, I used targeted perturbation of Ci-gsx: activity. This study indicated that Ci-gsx is actually involved in the molecular pathway controlling photoreceptor cells differentiation, upstream of Ci-Rx, a key gene for ocellus development. In addition, a detailed analysis of the 5' Ci-gsx regulatory region allowed me to identify the minimal promoter region responsible for Ci-gsx expression. Furthermore, I demonstrated that a member of Sox. family is likely involved in Ci-gsx transcriptional activation. I also identified Ci-msxb as a possible repressor of Ci-gsx extpression in pigment cell lineage. My data insert a new piece in the genetic cascade controlling early specification of Ciona sensory organs and represent a first evidence of a potential implication of a Gsx ParaHox. gene in this process, thus opening new perspectives OD the role. still controversial. of Gsx gene in the ancestor of bilaterians.

L'objectif général de ce groupe est de parvenir à une meilleure connaissance des caractéristiques - économiques, sociales et "techniques" - des agricultures antillaises de façon à enrichir l'analyse critique des politiques régionales de Développement agricole et rural, et à alimenter la nécessaire réflexion sur les tendances d'évolution actuelle des sociétés caribéennes et sur les alternatives de Développement pouvant s'offrir à elles. Il s'agit donc, d'une part, de contribuer au Développement et à l'articulation des résultats déjà produits et des travaux en cours, en proposant une structure et une problématique propices à cette synthèse, et d'autre part, de mettre à profit et de mobiliser le potentiel scientifique riche et diversifié existant pour la formation des cadres capables de préparer et de conduire des actions de Développement s'appuyant sur les réalités agricoles locales, situées dans leurcontextecaribéen. La démarche pédagogique et lecontenu du Magistère "Développement Agricole Caraïbe" (DAC) en découlent. ----- A Research-training group the objectif of which is the study and the analysis of "Caribbean Agrarian Systems and Alternatives of Development" (SACAD) works in the UAG. The general objective of this group is to reach a better knowledge on the economic, social and "technical" characteristics of Caribbean agricultures in order to enrich the critical analysis of the regional policies of agricultural and rural development, and to supply the necessary thought on the trends of present evolution of the Caribbean societies and their possible development alternatives. Therefore the matter is, on one hand to contribute to the development and to the linking of the already produced results and of the current works with proposing a structure and problematics propitions to this synthesis, and, on the other hand to benefit from and to summon up the existing rich and diversified scientific potential for the training of staff able to prepare and lead development actions relying on local agricultural facts and located in their Caribbean context.

description: A nonlinear model of spin wave excitation using a point contact in a thin ferromagnetic film is introduced. Large-amplitude magnetic solitary waves are computed, which help explain recent spin-torque experiments. Numerical simulations of the fully nonlinear model predict excitation frequencies in excess of 0.2 THz for contact diameters smaller than 6 nm. Simulations also predict a saturation and red shift of the frequency at currents large enough to invert the magnetization under the point contact. The theory is approximated by a cubic complex Ginzburg-Landau type equation. The mode's nonlinear frequency shift is found by use of perturbation techniques, whose results agree with those of direct numerical simulations.

Nuove prospettive dell’insularità. Procida Capitale Italiana della Cultura 2022

Year: 2021

description: La nomina di Procida quale Capitale Italiana della cultura per il 2022 con lo slogan "la cultura non isola" offre l'opportunità di rivalutare la condizione di insularità, da sempre associata ad una negativa idea di isolamento, facendone riscoprire l'efficace ruolo nella tutela del locale patrimonio paesaggistico, culturale ed identitario. Procida, collocata all'interno dell'ampia e rinomata regione turistica partenopea, grazie alle sue caratteristiche di attrattività, emerge anche rispetto alle più rinomate isole di Ischia e Capri. Il suo progetto si propone come modello esportabile ad altre piccole realtà insulari inserite ed interconnesse in più ampi distretti turistici nei quali siano in grado di emergere valorizzando la propria identità. L'insularità quindi va intesa non come ostacolo alle relazioni con l'esterno, ma come filtro a disposizione delle popolazioni locali per la gestione qualitativa e quantitativa dei flussi di visitatori. Attraverso la conduzione di una analisi SWOT[1] sono stati individuati i punti di forza e di debolezza della struttura territoriale allo scopo di suggerire le scelte più idonee ad ottimizzare gli effetti che la nomina ottenuta da Procida e le conseguenti attese ricadute sull'immagine potranno portare sullo sviluppo dell'isola in chiave sostenibile.

description: Numerical methods for the optimal transport problem is an active area of research. Recent work of Kitagawa and Abedin shows that the solution of a time-dependent equation converges exponentially fast as time goes to infinity to the solution of the optimal transport problem. This suggests a fast numerical algorithm for computing optimal maps; we investigate such an algorithm here in the 1-dimensional case. Specifically, we use a finite difference scheme to solve the time-dependent optimal transport problem and carry out an error analysis of the scheme. A collection of numerical examples is also presented and discussed.

description: Geographies of energy policies for the ecological transition after Covid-19 Keeping as a background the view that the low-carbon energy transition is fundamentally a geographical-political process, with powerful effects on the configuration of socio-economic models, the article focuses on the following three key issues: (i) The definition of the concept of sustainable energy policy transition, starting from space; (ii) The geographical and spatial dimensions of ecological transition policies in the face of the Covid-19 pandemic, looking at structures and scales of energy governance; (iii) Post-Covid spatial strategies by trying to observe the contents of the National Recovery and Resilience Plan (PNRR) in Italy, where, as is happening in other countries, the policy of sustainable energy transitions is now at a critical point, where the scale and directionality favored by the public sector for post-pandemic recovery will be crucial.

description: The Caribbean Farming Systems Research and Extension (FSR/E) Network was initiated at a workshop in St. Lucia in November 1988. The two day workshop was attended by FSR/E practitioners from National and Regional Organisations throughout the English, French and Spanish speaking Caribbean. The participants agreed unanimously on the need for an FRS/ Ε network in the region, with the following objectives : - encouraging information exchange between professionnals involved in FSR, - stimulating interest in FSR/E methodology, and - strengthening the FSR/E infrastructure in the region. The immediate goals of the network are the publication of a bibliography of FSR work, and a directory of FSR practitioners, and the production of a quarterly newsletter, in addition, the network would serve as a clearing house for identifying training needs, and facilitating consultations in FSR within the region. ----- Le réseau caraïbe sur la Recherche-Développement et la Vulgarisation (FSR/E) a été lancé lors d'un atelier qui s'est tenu à Sainte Lucie en Novembre 1988. Cet atelier de deux jours a été suivi par des praticiens de la FSR/E d'organisations nationales et régionales de la Caraïbe anglophone, francophone et hispanophone. A l'unanimité, les participants ont approuvé le besoin d'un réseau FSR/E avec les objectifs suivants : - encourager l'échange d'information entre les professionnels de la FSR/E, - stimuler l'intérêt pour la méthodologie de la FSR/E, - renforcer l'infrastructure de la FSR/E dans la région. Les buts immédiats du réseau sont la publication d'une bibliographie sur la Recherche-Développement (FSR), un répertoire des spécialistes de la FSR et la production d'une circulaire trimestrielle. De plus, le réseau servirait de lieu d'identification des besoins de formation et faciliterait les consultations de FSR dans la région.
