The acute effects of single versus multiple set resistance exercise on cognition and affect in untrained older adult women
Creators: name: Marcotte, Lauren
Publisher: name: University of British Columbia
Year: 2020

description: PURPOSE: Current evidence suggests chronic resistance exercise training (RET) improves older adults’ executive function; however, the effects of a single session of resistance exercise (RE) and dose (i.e., frequency, intensity, volume) on executive performance remains unclear. Thus, we investigated the effect of RE, at three different volumes, on executive function in healthy older women. METHODS: This was a within-subjects, crossover study design of 21 untrained, older women (65-75 years). At baseline, participants were familiarized with four RE machines (leg press, chest press, knee-extension and lat pull down) and performed a 10RM. Following a minimum of 7 days, participants randomly completed 3 RE conditions: 1, 3, or 5 sets of 10 repetitions (70%1RM; 120 sec rest between sets) for each exercise, and a control (CON) condition. We measured two executive processes: 1) inhibitory control using the Flanker task, and 2) cognitive flexibility using the Dimensional Change Card Sort (DCCS) task. We also measured the affective response to RE using the Feelings Scale. Using a linear mixed model, we determined the effect of different RE volumes (i.e., condition) and time (i.e., visit number), adjusting for baseline performance, on change in inhibitory control (i.e., after RE – before RE) and cognitive flexibility. We also examined the effect of both RE volume and time on change in affect (i.e., after RE – before RE) using a linear mixed model. RESULTS: At baseline, participants were physically healthy and did not have cognitive impairment (Montreal Cognitive Assessment (MoCA) scores > 26/30). There were no significant differences found for acute changes in flanker performance by condition performed (i.e., 1, 3, 5, or CON) (p=0.12) and by time (i.e., visit number) (p=0.84). Similarly, there was no effect of condition on acute changes in DCCS performance (p=0.66) or time (p=0.57). Change in affect was not significantly different by both condition (p=0.56) and time (p=0.09). CONCLUSION: Contrary to evidence showing RE can promote executive performance, our results suggest a single bout of RE did not improve executive function in healthy older women, irrespective of volume.

description: Il lavoro, realizzato in una seconda elementare di Locarno, desidera migliorare l’apprendimento nella lingua italiana di due allievi meno avanzati, attraverso un progetto di scrittura di una rivista di classe. La ricerca si focalizza sulle competenze dei due allievi che mostrano delle difficoltà nell’ambito della produzione di testi. Come futura docente, mi sono sempre interrogata su come affrontare le difficoltà degli alunni in questo ambito. I primi anni di scuola sono fondamentali e dovrebbero creare le premesse per sviluppare nei bambini l’entusiasmo sia verso la scrittura che per quanto riguarda la formazione in generale. Come motivare gli allievi che si mostrano poco interessati già nel primo ciclo di scuola elementare? In quale prospettiva è necessario lavorare per rendere l’apprendimento piacevole e interessante non solo per chi è in difficoltà, ma considerando anche tutta la classe? I dati raccolti permettono di evidenziare l’efficacia del lavoro cooperativo, alla base della realizzazione della rivista. In particolare, questo strumento ha dato ai due allievi meno avanzati la possibilità di migliorare le loro competenze nell’ambito della produzione di testi e ha permesso inoltre di alimentare la motivazione verso la lingua italiana.

description: Excerpts from the report: The 1957-58 survey of farmer marketing, farm supply, and related service cooperatives shows a substantial increase in the dollar volume of these cooperatives. Total gross value of farm products marketed, farm supplies handled, and receipts for services performed by cooperatives amounted to $14 billion compared with almost $13.5 billion in the previous year, representing an increase of almost 4 percent. Total net volume, after eliminating duplication resulting from interassociation business, amounted to almost $10. 7 billion. This is an increase of more than 3 percent over the net business of almost $10. 4 billion in 1956-57. The number of cooperatives decreased from 9,872 in 1956-57 to 9,716 in 1957-58, representing a net decrease of 156 associations. The total number of memberships in farmer cooperatives decreased for the second consecutive year. Memberships in 1957-58 were 7,485,090 compared with 7,671,730 in 1956-57.

description: The quantum degeneracy point approach [D. Vion et al., Science 296, 886 (2002)] effectively protects superconducting qubits from low-frequency noise that couples with the qubits as transverse noise. However, low-frequency noise in superconducting qubits can originate from various mechanisms and can couple with the qubits either as transverse or as longitudinal noise. Here, we present a quantum circuit containing a universal quantum degeneracy point that protects an encoded qubit from arbitrary low-frequency noise. We further show that universal quantum logic gates can be performed on the encoded qubit with high gate fidelity. The proposed scheme is robust against small parameter spreads due to fabrication errors in the superconducting qubits.

description: Die Pergamongrabung konzentrierte sich 2021 auf Arbeiten im Rahmen des neuen Forschungsprogramms TransPergMikro. Die Datierung der ›Gotenmauer‹ in das 3. Jh. n. Chr. konnte abgesichert werden. Entdeckung und Dokumentation eines kaiserzeitlichen Peristylgebäudes östlich der Roten Halle tragen weiter zur Kenntnis der Stadtentwicklung bei. Bei den nunmehr abgeschlossenen Untersuchungen des Amphitheaters und des Theaters am Musalla Mezarlığı wurden zum Teil überraschende Ergebnisse zu Entstehung, Aufbau und Aussehen der Großbauten erzielt. Mit dem ›Unteren Westlichen Gymnasion‹ wurde ein weiterer kaiserzeitlicher Großbau dokumentiert. Geophysikalische Prospektionen im Umfeld des Asklepieions haben neue Indizien für den Verlauf der Grenzen der städtischen Bebauung erbracht. Mit der Ausgrabung eines kaiserzeitlichen Grabbaus nordwestlich des Heiligtums konnte ein weiteres, aussagkräftiges Zeugnis für die Funeralkultur der kaiserzeitlichen Eliten Pergamons gewonnen werden. Der Umland-Survey konzentrierte sich auf die Übergangszone der östlichen Ausläufer der Kara Dağ-Halbinsel und der anschließenden westlichen Bakırçay-Ebene. Neben der diachronen Rekonstruktion der Landnutzung konnten mehrere Siedlungsplätze erstmals dokumentiert werden. Sie reichen von einem mutmaßlichen achämenidischen Dynastensitz über hellenistische Festungen mit Grenzmarkierungen bis zu einer weiteren kaiserzeitlichen Villa mit ausgedehnter spätantiker bis frühbyzantinischer Keramikproduktion. Die Rettungsgrabung an der im Vorjahr entdeckten Ballık-Höhle konnte die temporäre Präsenz epipaläolithischer Jäger und Sammler ebenso bestätigen wie die spätere Nutzung des Platzes als Heiligtum der Meter. Die Untersuchungen von Sedimentarchiven in Pergamon und der Flussebene durch die Physische Geographie wurden fortgesetzt. Die Maßnahmen der Baudenkmalpflege und Konservierung konzentrierten sich auf die Ostwand des Großen Gymnasions, auf die Theaterterrasse sowie auf den Unteren Rundbau im Asklepieion und auf die Sicherung einer hellenistischen Wanddekoration im Inkrustationsstil.

description: We design magnetic traps for atoms based on the average magnetic field of vortices induced in a type-II superconducting thin film. This magnetic field is the critical ingredient of the demonstrated vortex-based atom traps, which operate without transport current. We use Bean's critical-state method to model the vortex field through mesoscopic supercurrents induced in the thin strip. The resulting inhomogeneous magnetic fields are studied in detail and compared to those generated by multiple normally-conducting wires with transport currents. Various vortex patterns can be obtained by programming different loading-field and transport current sequences. These variable magnetic fields are employed to make versatile trapping potentials.

description: Die Bachelorarbeit befasst sich mit folgender Fragestellung: Weshalb gibt es Kinder mit einer Spracherwerbsstörung, welche in einer monolingual schweizerdeutschen Umgebung aufwachsen, jedoch Hochdeutsch anstatt Schweizerdeutsch als Grundsprache erwarben und diese Sprachvarietät zu präferieren scheinen? Das Ziel der Arbeit liegt darin, von Einzelfällen Gemeinsamkeiten und Unterschiede in Bezug auf die Fragestellung herauszuarbeiten und darzustellen. Die empirische Forschung wurde anhand von qualitativen Leitfadeninterviews mit den Eltern der Probanden und zwei Abklärungssequenzen mit Testungen zum Sprachstand der Kinder durchgeführt. Die Gemeinsamkeiten und Unterschiede in den beiden Sprachvarietäten wurden auf phonetisch-phonologischer und morphologisch-syntaktischer Ebene analysiert. Allen Elternteilen fiel früh die Verwendung hochdeutscher Ausdrücke bei ihren Kindern auf. Das Sprachverhältnis liegt bei den drei Hauptprobanden deutlich bei einem hochdeutschen Sprachgebrauch. Anhand des Falls der Zwillinge und dessen Informationserhebung kann man aufzeigen, dass weder das Elternhaus, das schulische Setting, der Medienkonsum noch die sprachliche Umgebung hochdeutschen Input anboten und daher diese vier Faktoren in diesem Einzelfall für eine mögliche Erklärung auszuschliessen sind. Es wurden Testungen zur rezeptiven und produktiven Sprachleistung durchgeführt. Dabei stellte sich das Sprachverständnis als unauffällig hinaus. Es müssen Faktoren betrachtet werden, welche expressiver Natur sind. Die empirische Untersuchung veranschaulichte zudem, dass es sich um eine Problematik auf phonetisch-phonologischer Ebene zu handeln scheint.

description: The expansion of a dense plasma through a more rarefied ionised medium is a phenomenon of interest in various physics environments ranging from astrophysics to high energy density laser- matter laboratory experiments. Here this situation is modeled via a 1D Particle-In-Cell simulation; a jump in the plasma density of a factor of 100 is introduced in the middle of an otherwise equally dense electron-proton plasma with an uniform proton and electron temperature of 10eV and 1keV respectively. The diffusion of the dense plasma, through the rarified one, triggers the onset of different nonlinear phenomena such as a strong ion-acoustic shock wave and a rarefaction wave. Secondary structures are detected, some of which are driven by a drift instability of the rarefaction wave. Efficient proton acceleration occurs ahead of the shock, bringing the maximum proton velocity up to 60 times the initial ion thermal speed.

description: La dimensione espressiva è una delle dimensioni della personalità dell’allievo presente nel piano di studio della scuola dell’obbligo ticinese. Lo scopo di questa ricerca è quello di indagare in maniera esplorativa la tipologia delle attività che suscitano negli allievi un’esperienza emozionale, positiva o negativa, e quali sono le motivazioni che essi adducono per spiegare il loro vissuto. Questo al fine di rendere la scelta delle attività espressive più ponderata rendendo l’insegnamento più efficace. Sessanta allievi appartenenti a tre classi (due terze ed una seconda) hanno partecipato allo studio effettuando un percorso di 8UD nel corso del quale hanno sperimentato 10 situazioni motorie distinte. Al termine di ogni attività è stato chiesto loro di indicare, attraverso un questionario, quali emozioni hanno provato e quale ne è stato il motivo. I risultati hanno evidenziato che la “battaglia delle statue”, la “staffetta dei mimi” e la “produzione collettiva di gruppo” hanno suscitato emozioni positive mentre sono state meno apprezzate le attività di interpretazione della musica e quelle legate alla danza. Si è evidenziata anche una differenza tra le classi: le seconde sono risultate globalmente più predisposte delle terze. È inoltre emerso che la possibilità d’interazione con il partner risulta essere un elemento che influisce in modo positivo sulla percezione dell’attività. Relatori: Alejandro Arigoni e Flavio Rossi.

description: En Venezuela la investigación es factor importante para su desarrollo y sostenibilidad. El producto de ese trabajo de indagación requiere de la publicación, con la que se juzga la productividad y honorabilidad del científico. Lamentablemente, en nuestros espacios académicos se ha vuelto costumbre postergar para el futuro la publicación de los resultados de la investigación. Muchos problemas originan ese retardo: los conflictos de intereses hacen que sus hallazgos, de por sí valiosos, terminen perdiéndose en el tiempo, malgastando todos los esfuerzos realizados y los recursos invertidos. Todo eso deriva en el abandono de las líneas de investigación y repercute negativamente en la procura de recursos financieros para la consolidación de las metas, mermando la capacidad productiva de la labor de los investigadores. Por esto es necesario un cambio radical en el paradigma de gestión investigativa. Lo primero que tendríamos que preguntarnos es cómo ajustar un nuevo rumbo, tanto en formación académica sobre la metodología de investigación así como, de aptitud de publicación.

description: Il presente lavoro di diploma concerne l’autovalutazione svolta dagli allievi di scuola media e si focalizza sull’implementazione di pratiche autovalutative nella scrittura, analizzandone strumenti e dinamiche. In particolare lo scopo di questa ricerca-azione è quello di testare diverse conformazioni del rapporto tra valutazione oggettiva e valutazione soggettiva sia nel contesto di prove formative che sommative indagandone i risvolti psicologici e sociali all’interno della classe. La sperimentazione permetterà inoltre di sondare praticità ed efficacia di alcuni strumenti valutativi utilizzati durante il percorso. I risultati sono messi in relazione con lo stato della ricerca in questo campo e con altre esperienze simili. L’analisi dei dati dimostra la buona praticità ed efficacia di una rubrica valutativa co-costruita per lo sviluppo delle competenze di scrittura e, parzialmente, anche di uno strumento di autovalutazione semplice quale il semaforo. In riferimento al rapporto tra prospettiva soggettiva e oggettiva nella valutazione di una stessa manifestazione di competenza, il lavoro mette in luce la necessità di un percorso progressivo e prolungato che permetta una ridefinizione dei rapporti sociali e in particolare del rapporto di potere fra docente e discenti. Soltanto in questo modo si può infatti ambire ad una forma di autovalutazione che sia formativa per gli alunni e concorra a favorire la loro assunzione di responsabilità su tutto l’arco del processo di apprendimento.

morphologische Bewusstheit
Test

description: Internationale Studien belegen den Zusammenhang zwischen schriftsprachlichen Fähigkeiten von Schülern und Schülerinnen und deren morphologischen Bewusstheit. Es bestehen Hinweise darauf, dass lese-/rechtschreibschwache Kinder von einer frühen Förderung morphologischer Kompetenzen profitieren können. Im deutschsprachigen Raum und insbesondere in der Deutschschweiz wurde zur morphologischen Bewusstheit bei Kindergartenkindern noch kaum Forschung betrieben, und es besteht Bedarf an einem spezifischen Messinstrument, welches die Erfassung morphologischer Fähigkeiten vor Schuleintritt ermöglicht. Die vorliegende Arbeit befasst sich mit der Entwicklung eines mündlichen Tests zur Erfassung der morphologischen Bewusstheit bei Vorschulkindern. Aufgrund einer Literaturrecherche wurden konkrete Aufgaben entwickelt, anhand welcher die morphologische Bewusstheit von Kindern im 2. Kindergarten im Kanton Zürich erhoben werden kann. Der entwickelte Test wurde an sechs Kindern erprobt. Um Erkenntnisse über die Validität der Testaufgaben zu gewinnen, wurde der Zusammenhang zwischen dem entwickelten Messinstrument und bestehenden Testaufgaben, die ähnliche Dimensionen des Konstrukts morphologische Bewusstheit erfassen, analysiert. Die Evaluation zeigte, dass die Ergebnisse der beiden Testungen miteinander korrelieren. Die entwickelten Aufgabenstellungen eignen sich jedoch nicht alle in gleichem Masse, um die morphologische Bewusstheit bei Kindern im 2. Kindergarten zu erfassen. In einem weiteren Schritt sollte der Test daher überarbeitet werden. Ausserdem sollte untersucht werden, ob die durch den Test erfassten Fähigkeiten, wie aufgrund anderer Studien zu erwarten ist, auch bei Kindern in der Schweiz als Prädiktoren für den Schriftspracherwerb gelten.
New Approach to foot orthotics materials : hydrogel insoles
Creators: name: Kermen, Emre
Publisher: name: University of British Columbia
Year: 2020

description: Orthotics have been utilized by clinicians for many years to treat foot-related abnormalities. With advancements in material sciences, the footwear industry started utilizing synthetic materials which have better and suitable properties. Clinicians, who prescribe foot insoles, need to have an extensive understanding of the properties and characteristics of insole materials, to make informed decisions to meet the patients' needs. This thesis showcases utilized techniques and systems to evaluate orthosis properties as well as current criteria to date. Researchers have utilized a variety of testing techniques to examine properties of insole materials including; bench testing, simulated in-shoe conditions, in-shoe testing, and finite element analysis. Even though, there is a great understanding of material properties with endless diverse composition and thicknesses of each material makes clinical recommendations on the choice of material an impossible task. As the footwear orthosis industry shifts the focus from material to design, some researchers explore various anisotropic materials to create a homogeneous insole that can support as well as relieve pressure on patient’s feet. The objective of this research entails design and evaluation of novel hydrogel material in the field of foot orthotics. To accomplish this, first the material and design criteria of insoles had to be identified. This was followed by design and fabrication of insole molds. One of the requirements of hydrogel synthesis was development of molds to shape the solution. Extended finite element analysis of the human foot model along with insole designs were conducted to validate the designs. Manufacturing prototypes phase begun with design and expansion of an exterior thermal cycling bath that could enclose the orthotic. The hydrogel samples that were synthesized within the bath were taken through material testing validating the application of the hydrogel in the footwear field.

description: This graduate work of the master is devoted to the study and implementation of methods for solving problems of ultrasound tomography using supercomputer resources. The paper considers such approaches as ray tracing and wave equation. The first Chapter introduces the subject area and reviews existing solutions. The second Chapter deals with the theoretical model of the direct and inverse problem by ray and analytical methods, as well as data on the supercomputer environment setup. The third Chapter provides an implementation of the direct and inverse ray tracing problem, and compares the results of different ways of sorting sonogram traces used in solving the inverse problem.

description: The dynamical fermion mass generation on a 3-brane in the 5D space-time is discussed in a model with bulk fermions in interaction with fermions on the brane assuming the presence of a constant abelian gauge field component $A_5$ in the bulk. We calculate the effective potential as a function of the fermion masses and the gauge field component $A_5$. The masses can be found from the stationarity condition for the effective potential (the gap equation). We formulate the equation for the mass spectrum of the 4D--fermions. The phases with finite and vanishing fermion masses are studied and the dependence of the masses on the radius of the 5th dimension is analyzed. The influence of the $A_5$-component of the gauge field on the symmetry breaking is considered both when this field is a background parameter and a dynamical variable. The critical values of the $A_5$ field, the coupling constant and the radius are examined.

description: The immune system of sea turtles is not completely understood. Sea turtles (as reptiles) bridge a unique evolutionary gap, being ectothermic vertebrates like fish and amphibians and amniotes like birds and mammals. Turtles are ectotherms; thus, their immune system is influenced by environmental conditions like temperature and season. We aim to review the turtle immune system and note what studies have investigated sea turtles and the effect of the environment on the immune response. Turtles rely heavily on the nonspecific innate response rather than the specific adaptive response. Turtles’ innate immune effectors include antimicrobial peptides, complement, and nonspecific leukocytes. The antiviral defense is understudied in terms of the diversity of pathogen receptors and interferon function. Turtles also mount adaptive responses to pathogens. Lymphoid structures responsible for lymphocyte activation and maturation are either missing in reptiles or function is affected by season. Turtles are a marker of health for their marine environment, and their immune system is commonly dysregulated because of disease or contaminants. Fibropapillomatosis (FP) is a tumorous disease that afflicts sea turtles and is thought to be caused by a virus and an environmental factor. We aim, by exploring the current understanding of the immune system in turtles, to aid the investigation of environmental factors that contribute to the pathogenesis of this disease and provide options for immunotherapy.

description: We provide a new way of constraining the relative scintillation efficiency L_eff for liquid xenon. Using a simple estimate for the electronic and nuclear stopping powers together with an analysis of recombination processes we predict both the ionization and the scintillation yields. Using presently available data for the ionization yield, we can use the correlation between these two quantities to constrain L_eff from below. Moreover, we argue that more reliable data on the ionization yield would allow to verify our assumptions on the atomic cross sections and to predict the value of L_eff. We conclude that the relative scintillation efficiency should not decrease at low nuclear recoil energies, which has important consequences for the robustness of exclusion limits for low WIMP masses in liquid xenon Dark Matter searches.

description: In this paper we classify SL_2-actions on normal affine T-varieties that are normalized by the torus T. This is done in terms of a combinatorial description of T-varieties given by Altmann and Hausen. The main ingredient is a generalization of Demazure's roots of the fan of a toric variety. As an application we give a description of special SL_2-actions on normal affine varieties. We also obtain, in our terms, the classification of quasihomogeneous SL_2-threefolds due to Popov.

description: The collisions of cosmic strings loops and the dynamics of junctions formations in expanding backgrounds are studied. The key parameter controlling the dynamics of junctions formation, the cosmic strings zipping and unzipping is the relative size of the loops compared to the Hubble expansion rate at the time of collision. We study analytically and numerically these processes for large super-horizon size loops, for small sub-horizon size loops as well as for loops with the radii comparable to the Hubble expansion rate at the time of collision.

description: Im Rahmen des kooperativen Forschungsprojekts „Aktivitäten-geleitete Aphasie Diagnostik (AgAD)“ der Interkantonalen Hochschule für Heilpädagogik (HfH) und der Schweizerischen Hochschule für Logopädie Rorschach (SHLR) wird eine konsequent von der Aktivitätsebene ausgehende Diagnostik entwickelt. Ziel der vorliegenden Arbeit ist es, zu untersuchen, welches bedeutsame Aktivitäten für Menschen mit Aphasie in der Deutschschweiz sind. Damit leistet die Arbeit einen Beitrag zum Projekt AgAD und unterstützt die Auswahl der Aktivitätsitems. Es wird erfasst, welche Aktivitäten in die Auswahl der drei wichtigsten Aktivitäten gelangen, welche Aktivität innerhalb einer Domäne der Internationalen Klassifikation der Funktionsfähigkeit, Behinderung und Gesundheit (ICF) am wichtigsten bewertet wird und ob es dabei einen Unterschied zwischen Menschen über und unter 65 Jahren gibt. Zudem wird festgehalten, welche Aktivitäten von Proband:innen häufig zusätzlich genannt werden. Um die Fragestellungen zu beantworten, wurden im Rahmen des Projekts AgAD Menschen mit Aphasie quantitativ mit einer erweiterten Version des FATMA 2.1, welcher Aktivitäts- und Teilhabeziele erfasst, zu wichtigen Aktivitäten in ihrem Alltag befragt. Die Befragung zeigte unter anderem, dass die Stichprobe die Aktivitäten ‚sich unterhalten‘ und ‚E-Mail schreiben‘ als die wichtigsten ansah. Viele Proband:innen nannten zusätzliche für sie bedeutsame Aktivitäten, wie beispielsweise den Computer zu benutzen oder ein Hörbuch hören und verstehen zu können.
A Direct Proof of BCFW Recursion for Twistor-Strings

description: This paper gives a direct proof that the leading trace part of the genus zero twistor-string path integral obeys the BCFW recursion relation. This is the first complete proof that the twistor-string correctly computes all tree amplitudes in maximally supersymmetric Yang-Mills theory. The recursion has a beautiful geometric interpretation in twistor space that closely reflects the structure of BCFW recursion in momentum space, both on the one hand as a relation purely among tree amplitudes with shifted external momenta, and on the other as a relation between tree amplitudes and leading singularities of higher loop amplitudes. The proof works purely at the level of the string path integral and is intimately related to the recursive structure of boundary divisors in the moduli space of stable maps to CP^3.

description: The transition quadrupole moments, $Q_{\rm t}$, of four weakly populated collective bands up to spin $\sim$ $65\hbar$ in $^{157,158}$Er have been measured to be ${\sim}11 {\rm eb}$ demonstrating that these sequences are associated with large deformations. However, the data are inconsistent with calculated values from cranked Nilsson-Strutinsky calculations that predict the lowest energy triaxial shape to be associated with rotation about the short principal axis. The data appear to favor either a stable triaxial shape rotating about the intermediate axis or, alternatively, a triaxial shape with larger deformation rotating about the short axis. These new results challenge the present understanding of triaxiality in nuclei.

description: Lo yoga a scuola e nella quotidianità è una ricerca volta all’identificazione dei benefici che tale pratica può portare a dei bambini di seconda elementare. La ricerca è stata applicata su un arco temporale di 8 mesi e aveva come scopo quello di osservare in che modo gli allievi cogliessero i nuovi insegnamenti proposti a scuola e come questi venivano da loro gestiti. Al fine di ottenere dei risultati, ho strutturato un percorso di yoga ispirato al libro “Piccolo Yoga” di Clemi Tedeschi (2016) che si è poi ampliato diventando non solo un momento fine a sé stesso (lezione di yoga) bensì un’azione a cui ricorrere ogni qualvolta i bambini necessitassero qualche minuto di riflessione e/o rilassamento all’interno dell’aula. I risultati hanno dimostrato che lo yoga è stato un’occasione per migliorarsi in almeno una delle sfere bio-psico-sociali. Il 90% degli allievi ha comunicato e spiegato positivamente a terzi il funzionamento del percorso, il 50% ha intrapreso dei cambiamenti personali anche al di fuori del contesto scolastico e il 30% ha iniziato a praticare lo yoga anche al di fuori dell’aula scolastica.

description: The coherent spin-polarized electron transport through a zigzag-edge graphene flake (ZGF), sandwiched between two semi-infinite armchair graphene nanoribbons, is investigated by means of Landauer-Buttiker formalism. To study the edge magnetism of the ZGF, we use the half-filled Hubbard model within the Hartree-Fock approximation. The results show that the junction acts as a spin filter with high degree of spin polarization in the absence of magnetic electrodes and external fields. By applying a gate voltage the spin-filtering efficiency of this device can be effectively controlled and the spin polarization can reach values as high as 90%.

Rilassiamoci... alla scuola dell'infanzia: un percorso di rilassamento e di visualizzazione mentale

description: Ognuno di noi vive nella propria quotidianità momenti di tensione, ansia e stress; a volte sarebbe necessario fermarsi, riflettere e la soluzione potrebbe sorgere spontanea: rilassiamoci! Con questa ricerca, si indagano gli effetti del rilassamento sui comportamenti dei bambini e sul clima di lavoro, durante le attività successive. Inoltre, si rilevano le differenze in merito ai comportamenti degli allievi e al clima di lavoro nelle attività, rispetto alla presenza o all’assenza di un rilassamento a priori. Lungo il percorso si svolgono con 7 bambini del III livello di Scuola dell’Infanzia delle sequenze di rilassamento, cui seguono delle attività a tavolino; attraverso la stesura di un diario di bordo si raccolgono gli esiti di questi momenti. In seguito, ci si dedica al confronto in merito alla presenza o all’assenza di un rilassamento e i dati sono raccolti attraverso una checklist, sulla base degli indicatori emersi dal diario di bordo, e attraverso i filmati delle attività. Questi ultimi sono mostrati a sei persone esterne alla ricerca, le quali forniscono il loro prezioso contributo identificando a quali attività è preceduto un rilassamento. Gli esiti ottenuti riconoscono degli effetti positivi al rilassamento, che permettono ai bambini di lavorare con una ritrovata tranquillità. In assenza di un rilassamento, la tensione è spesso presente e si esprime in comportamenti inadeguati e toni di voce elevati; per aiutarli, non resta che rilassarsi. Relatore: Davide Antognazza.
Tensile development during refining of mixtures of nbsk and hardwood pulp
Creators: name: Mitra, Sudipta Kumar
Publisher: name: University of British Columbia

description: Blending of different pulps prior to Low consistency (LC) refining is common operation in paper making. LC refining is a process used to modify the morphology of the fibres in order to increase tensile strength of paper. The aim of this dissertation is to understand the difference in mechanism between separate and co-refined pulp fibre mixtures and to achieve a scaling law to understand tensile increase. This work was conducted in three separate studies using vastly different refining treatments, namely compression refining, PFI and pilot scale disk refiner. We examined the tensile strength, T response of mixture of softwood (NBSK) and hardwood (eucalyptus) to various energy, E and intensity, I of treatments. We advanced for the first time a scaling law of the form TL/k=f(E,I) which collapsed all data for the different suspension and argued its utility through consolidation theory. Here k is the permeability of the suspension and L is the fibre length. Hence, we achieve similarity between all treatments. We also note a curious result that ordering of the refining treatment affects the tensile strength increase. We demonstrate that a large tensile strength is gained if the pulp suspensions are mixed first, and then refined, as opposed to refined then mixed. Further work is required to understand this effect.
