Heat pulses in Al203 single crystals at low temperatures.
Creators: name: Chung, David Yih
Publisher: name: University of British Columbia
Year: 2011

description: Heat pulse experiments have been made on Al₂O₃ single crystals in the temperature range 3.8° K to 35°K with the aim of gaining further insight into the nature of heat transport in solids at low temperatures. Short heat pulses were produced by heating a thin metal film evaporated on to one end of the crystal. The thermal pulse arriving at the other end of the crystal was detected by an indium film thermometer placed in a coil connected to a sensitive radio-frequency bridge, so that the variation of resistance was finally displayed on an oscilloscope. The pulses received at low temperatures (3.8°K to 8°K) show two quite separate parts, an initial sharp rise followed by a slow rise, starting at a definite delay time corresponding to the phonon velocity in the medium. The results up to 18°K do not show appreciable variation in delay time, showing that the heat pulse propagation has not entered a second sound region. As the temperature increases, the amplitude of the initial phonon pulse decreases very much compared with the amplitude of the slow rise. Above 18°K, the small sharp rise can no longer be seen clearly so that the delay time is no longer well defined, and at 30°K only the slow rise is observed. It is found that the conventional theory of heat conduction is inadequate to interpret our results at low temperatures, as it fails to predict the finite delay of the initial rise of the received pulse. A phenomenological approach is taken, using a modified heat equation which has an electrical transmission line analogy. Using Laplace transforms, a solution is obtained and the results calculated with a computer are compared with the experimental curves. It is found that the pulse shape can be interpreted quite satisfactorily, especially at the lowest temperatures. The thermal diffusivity, D, for different temperatures is found, and the apparent thermal conductivity, K, is calculated and compared with Herman's (1955) results. The solution of the modified heat equation is also calculated for liquid He II at 0.25°K and compared with the heat pulses observed by Kramers et al (1954); very good agreement is obtained.
title: Children of a foreign background: Aspirations after compulsory education in Iceland
Creators: name: Sigurðardóttir, Eva Dögg
Publisher: name: University of Kent

description: The foreign population in Iceland has changed rapidly over the past few decades, moving from a homogenous to a more diverse population. These changes have posed new challenges in the Icelandic educational system. Unfortunately, Icelandic studies suggest that some schools are not fully equipped to respond to these challenges. Furthermore, children of foreign background seem to fare worse in school, are more likely to discontinue with their studies after compulsory education and are less likely to graduate from upper secondary school than their Icelandic counterparts. To better understand the openness of the Icelandic school system, this thesis addresses the question: How do we explain the differential educational aspirations, if any, between children of foreign background and native background in Iceland in the last 3 years of compulsory school in Iceland? This is a mixed methods study, based on a survey distributed in 17 schools in Iceland among students of Icelandic and foreign background, and interviews with 32 students of foreign background. The data was specifically gathered for the purpose of this study. This thesis sets out to understand how educational aspirations are formed, in order to recognise the barriers that may hinder students of foreign background in Iceland in reaching their educational goals and dreams. The study has established that although students of foreign background may be less certain about going to upper secondary school, this difference disappeared once other factors were controlled for. Rather, the main hindrances are revealed by the qualitative data. Finally, this research calls for a shift in focus from the schools and extend the conversation to societal factors and how the system as a whole can support a truly equitable educational system.

Luminosity Functions of Type Ia Supernovae and their Host Galaxies from the Sloan Digital Sky Survey

description: The sample of 137 low-redshift type Ia supernovae with 0.05 < z < 0.3 obtained from the SDSS-II Supernova Survey for the southern equatorial stripe of 300 square degrees is used to derive the luminosity functions of type Ia supernovae and of their host galaxies in the gri passbands. We show that the luminosity function of type Ia supernova host galaxies matches well with that of galaxies in the general field, suggesting that the occurrence of type Ia supernovae does not favour a particular type of galaxies but is predominantly proportional to the luminosity of galaxies. The only evidence that points to possible correlation between the supernova rate and star formation activity is that the supernova rate in late-type galaxies is higher than that in early-type galaxies by 31+/-35%. The sample contains 8 type Ia supernovae whose host galaxies were not identified, but it is shown that their occurrence is consistent with them occurred in low luminous galaxies beyond the survey. The luminosity function of type Ia supernovae is approximately Gaussian with the full-width half maximum being a factor of 1.4 in luminosity. The Gaussian distribution becomes tighter if the ratio of extinction to reddening, R_V, is lower than the characteristic value for the Milky Way and if luminosity is corrected for the light curve shape. The colour excess is ~0.07 mag which is significantly smaller than reddening expected for field galaxies. This colour excess does not vary with the distance of the supernovae from the centre of the host galaxy to 15 kpc. This suggests that the major part of the colour excess appears to be either intrinsic or reddening that arises in the immediate environment of supernova, rather than interstellar reddening in host galaxies.

description: Качество воздуха в помещениях становится все более важной проблемой для общественного здравоохранения. Использование для этих целей систем кондиционирования воздуха (сплитсистем) в России неуклонно растет, но системы кондиционирования воздуха могут быть загрязнены микроорганизмами, которые являются одним из наиболее важных источников загрязнения воздуха внутри помещений и одним из факторов, способствующих «синдрому больного помещения». Биоаэрозоли в воздухе помещений, содержащие грибки, бактерии и вирусы могут вызывать аллергические и инфекционные заболевания. Целью настоящего исследования явилась оценка уровня бактериального и грибкового загрязнения элементов сплит-системы и воздуха кондиционированных помещений. Метод исследования включал количественный учет микроорганизмов на поверхностях фильтров сплит-систем и в воздухе университетских аудиторий. Установлено, что после часовой работы кондиционера количество микроорганизмов в воздухе уменьшилось на 41,4 %. При этом микробный пейзаж изменялся в сторону увеличения процентного соотношения плесневых грибов, среди которых доминировали представители родов Aspergillus (Aspergillus niger, Aspergillus flavus, Aspergillus fumigatus, Aspergillus ochraceus и Aspergillus versicolor), Penicillium (Penicillium aurantiogriseum, Penicillium viridicatum, Penicillium chrysogenum, Penicillium citrinum) и Trichoderma. Характерной особенностью биоаэрозолей воздушной среды учебных аудиторий является присутствие большого количества кокковых микроорганизмов.

It is compatible with the fact that the corresponding geometries are dual to non-relativistic CFTs whose symmetry algebra is the Schrodinger algebra which admits an extension to an infinite dimensional symmetry algebra containing a Virasoro subalgebra.

Отмечено, что в процессе переработки мясных продуктов образуются костные отходы в количестве 17 800 тонн в год. Результаты анализа показали, что в настоящее время костные отходы не подвергаются переработке и непрерывно направляются на общегородскую свалку. С учетом этих обстоятельств изучены процессы пиролиза костных отходов при широких интервалах изменения температуры. Осуществлено физико-химическое моделирование деструкции костных отходов путем составления химической матрицы твердой фазы. Установлено концентрационное распределение конденсированной фазы, индивидуальных химических соединений и отдельных частиц. Показано образование в значительных количествах кальций- и фосфорсодержащих веществ, что полезно при использовании их в качестве кормовых добавок для животных и в виде минеральных удобрений в сельскохозяйственных работах.
Factors influencing gas exhange in the rainbow trout (Salmo gairdneri)
Creators: name: Holeton, George F.
Publisher: name: University of British Columbia
Year: 2011

description: A study of factors affecting gas exchange at the gills of rainbow trout during hypoxia was made. Techniques for implanting cannulae in the buccal and opercular chambers, the dorsal aorta, and the ventral aorta are described. The responses of afferent and efferent blood and water pressures, Po₂, PCo₂, pH, and the hematocrit of efferent blood were made while the unanaes thetized free swimming trout was in a sealed respirometer. The fish were allowed to consume the oxygen in the respirometer to produce conditions of hypoxia. Determination of oxygen uptake and a knowledge of the solubility of oxygen in blood and water allowed indirect estimation of ventilation volume, cardiac output and stroke volume of the heart. With this knowledge, inferences on the function of circulatory and respiratory mechanisms during hypoxia were drawn. The rainbow trout possesses a number of homeostatic mechanisms which augment oxygen uptake during hypoxia. It was found that the trout could maintain a fairly uniform oxygen uptake in environmental oxygen tensions as low as 30 to 50 mm Hg„ The major homeostatic responses to hypoxia affecting oxygen uptake were: an increase in ventilation volume, an increase in the functional capacity of the blood, and an apparent vascular shunting of blood closer to the surface of the respiratory epithelium. No significant increase in cardiac output was observed. Since there was a pronounced bradycardia with hypoxia the stroke volume was apparently increasing. The role of the bradycardia, which has usually been associated with a reduction in cardiac output, is not clear. Possible reasons and functions of the bradycardia are discussed.

description: We have developed a new programming framework, called Sieve, to support parallel numerical PDE algorithms operating over distributed meshes. We have also developed a reference implementation of Sieve in C++ as a library of generic algorithms operating on distributed containers conforming to the Sieve interface. Sieve makes instances of the incidence relation, or \emph{arrows}, the conceptual first-class objects represented in the containers. Further, generic algorithms acting on this arrow container are systematically used to provide natural geometric operations on the topology and also, through duality, on the data. Finally, coverings and duality are used to encode not only individual meshes, but all types of hierarchies underlying PDE data structures, including multigrid and mesh partitions. In order to demonstrate the usefulness of the framework, we show how the mesh partition data can be represented and manipulated using the same fundamental mechanisms used to represent meshes. We present the complete description of an algorithm to encode a mesh partition and then distribute a mesh, which is independent of the mesh dimension, element shape, or embedding. Moreover, data associated with the mesh can be similarly distributed with exactly the same algorithm. The use of a high level of abstraction within the Sieve leads to several benefits in terms of code reuse, simplicity, and extensibility. We discuss these benefits and compare our approach to other existing mesh libraries.

description: The atomistic to continuum interface for quasicontinuum energies exhibits nonzero forces under uniform strain that have been called ghost forces. In this paper, we prove for a linearization of a one-dimensional quasicontinuum energy around a uniform strain that the effect of the ghost forces on the displacement nearly cancels and has a small effect on the error away from the interface. We give optimal order error estimates that show that the quasicontinuum displacement converges to the atomistic displacement at the optimal rate O($h$) in the discrete $\ell^\infty$ norm and O($h^{1/p}$) in the $w^{1,p}$ norm for $1 \leq p < \infty.$ where $h$ is the interatomic spacing. We also give a proof that the error in the displacement gradient decays away from the interface to O($h$) at distance O($h|\log h|$) in the atomistic region and distance O($h$) in the continuum region. E, Ming, and Yang previously gave a counterexample to convergence in the $w^{1,\infty}$ norm for a harmonic interatomic potential. Our work gives an explicit and simplified form for the decay of the effect of the atomistic to continuum coupling error in terms of a general underlying interatomic potential and gives the estimates described above in the discrete $\ell^\infty$ and $w^{1,p}$ norms.

В рамках исследования было проведено технолого-экономическое моделирование с целью сравнения двух технологических схем очистки, для одной из которых применяется традиционная схема биологической очистки — аэротенк-вторичный отстойник, а для второй биологическая очистка происходит с применением мембранных биореакторов. В ходе технологического моделирования были получены и сопоставлены концентрации загрязнений после очистки по каждой из схем, а также рассчитаны величины возможного вреда водным объектам. В рамках моделирования величин затрат были получены капитальные и эксплуатационные затраты для двух вариантов, и проанализированы ключевые отличия в их формировании. Отмечается, что при классической схеме очистки требуется возведение большего объема сооружений, в то время как для схем с мембранным биореактором значительной статьей затрат является приобретение собственно мембранных модулей, однако по мере увеличения производительности системы доля этих затрат снижается.

description: Металлургическое производство занимает одно из первых позиций по загрязнению окружающей среды, поскольку является опасным источником загрязнения атмосферы отходящими газами и твердыми выбросами, в которых содержатся различные тяжелые токсичные вещества. Огромное количество выбросов металлургического производства наносит большой вред окружающей среде, здоровью населения. Поэтому основная цель работы заключается в анализе систем экологического контроля в Норильске. Для определения состояния окружающей среды в работе был использован экологический мониторинг. Автором описаны модели производственного и общественного контроля над атмосферным воздухом. Были изучены обязанности осуществления производственного экологического контроля, закрепленные на законодательном уровне. Также был проведен анализ законодательных актов, в том числе закона «Об охране окружающей среды», и определено их значение как для предпринимателей, так и для окружающей среды. Дана короткая характеристика проектам, проведенным в год экологии в России. Охарактеризированы их основные результаты. Предложена модель, направленная на реализацию конституционного права каждого горожанина на достоверную информацию о состоянии окружающей среды. Определена ее роль для граждан и общественных объединений. Инструментом реализации права выступает экологическое просвещение, составным элементом которого является получение экологической информации. Внимание уделено особенностям использования приложений «Эковизор», AirVisual, веб-сайта. Сделаны выводы об общем состоянии окружающей среды в Норильске и определено влияние ее загрязнения на здоровье и качество жизни людей. Указаны аргументы о необходимости усовершенствования законодательства, обоснована роль общественности в принятии экологически значимых решений.

description: We reconsider the theory of magnetoresistance in hopping semiconductors. First, we have shown that the random potential of the background impurities affects significantly preexponential factor of the tunneling amplitude which becomes to be a short-range one in contrast to the long-range one for purely Coulomb hopping centers. This factor to some extent suppresses the negative interference magnetoresistance and can lead to its decrease with temperature decrease which is in agreement with earlier experimental observations. We have also extended the theoretical models of positive spin magnetoresistance, in particular, related to a presence of doubly occupied states (corresponding to the upper Hubbard band) to the case of acceptor states in 2D structures. We have shown that this mechanism can dominate over classical wave-shrinkage magnetoresistance at low temperatures. Our results are in semi-quantitative agreement with experimental data.

description: We consider two-party quantum protocols starting with a transmission of some random BB84 qubits followed by classical messages. We show a general "compiler" improving the security of such protocols: if the original protocol is secure against an "almost honest" adversary, then the compiled protocol is secure against an arbitrary computationally bounded (quantum) adversary. The compilation preserves the number of qubits sent and the number of rounds up to a constant factor. The compiler also preserves security in the bounded-quantum-storage model (BQSM), so if the original protocol was BQSM-secure, the compiled protocol can only be broken by an adversary who has large quantum memory and large computing power. This is in contrast to known BQSM-secure protocols, where security breaks down completely if the adversary has larger quantum memory than expected. We show how our technique can be applied to quantum identification and oblivious transfer protocols.

Agency and Decision-making with Advocacy Support: a qualitative study of people with dementia living alone
Creators: name: Dwan, C
Publisher: name: University Of Tasmania
Year: 2023
Subjects: Aged health care

description: This thesis explores the power of people with dementia who live alone to participate in decision-making processes with advocacy support. Although the benefits of consumer participation in healthcare decisions include improvements in health outcomes, greater emotional well-being and long-term cost savings, people with dementia who live alone are frequently marginalised in the decision-making process. This is significant given that this group is increasing in number and is overrepresented in statistics on early admission to institutional care. This study specifically examined how dementia affected the agency of people living alone, and how a dementia advocacy service influenced their participation in decision-making. The study employed multiple methods to collect qualitative data from nine people with dementia living alone who have used advocacy services, four dementia advocates and twenty-one healthcare professionals involved in meeting careassessment needs and in referring clients to the advocacy service. A critical realist theoretical framework and a process of retroduction were used to develop an explanatory theory. This study found that dementia significantly constrained agency and led to a narrowing of the social world of participants with dementia. Orientations of agency towards the present and future improved power of agency as did a person’s belief in their ability to take action, and advocacy was shown to positively influence these factors. Participation in decision-making was found to be extremely important to participants with dementia but sociocultural factors restricted their participation. Lack of understanding of the variation in decision-making capacity associated with dementia and a strong cultural focus on risk avoidance resulted in low prioritisation of decision-making involvement by healthcare professionals. In contrast, advocacy facilitated participation through trusting relationships, spending time to understand the person’s wishes and promoting the rights of the person with dementia living alone. These findings suggest the need for healthcare services to focus on enhancing agency, to encourage supportive decision-making, and to balance safety and emotional consequences of decisions when working with people with dementia living alone. Further, although advocacy provided benefits in protecting and facilitating participation, future success is contingent upon the establishment of a common understanding of advocacy and the advocate role and a universal approach to capacity and risk assessments.

комфортная среда для пешеходов

description: В целях создания комфортной городской среды в настоящее время органами власти проводится работа с населением по сокращению удельной доли поездок на личном автомобиле и поощрению использования альтернативных видов передвижений, в том числе пеших и с помощью низкоскоростных индивидуальных транспортных средств. Целесообразность таких действий подтверждена многочисленными исследованиями сложившейся городской среды, сформировавшейся на основе всеобщей доступности личного автомобиля. Автомобиль, как личное средство транспорта, хранится в непосредственной близости от места проживания. В условиях плотной застройки крупных городов, сформированной по нормам, не учитывающим владение автомобилем основной массы населения, а также современной многоэтажной застройки в условиях дефицита земельных ресурсов, население сталкивается с проблемой перегруженности придомовых территорий личными автомобилями, что ведет к конфликтам между соседями. В этих условиях становится актуальной проблема организации жилых элементов планировочной структуры, ориентированных на пешеходные передвижения и передвижения с помощью низкоскоростных индивидуальных транспортных средств. В связи с этим возникает вопрос реорганизации жилой среды и выявление территориальных резервов для изменений. В данной статье приведены результаты исследования плотной застройки жилых районов на предмет выявления возможностей ее реорганизации на базе принципов пешеходной доступности и доступности для низкоскоростных индивидуальных транспортных средств. Для исследования использован проектный метод. Данный метод позволил установить количественную величину территориальных ресурсов, возможных для перераспределения по функциональному назначению, при условии обеспечения соответствия интенсивности использования территории нормативам градостроительного проектирования.
Statistics of renormalized on-site energies and renormalized hoppings for Anderson localization models in dimensions d=2 and d=3

description: For Anderson localization models, there exists an exact real-space renormalization procedure at fixed energy which preserves the Green functions of the remaining sites [H. Aoki, J. Phys. C13, 3369 (1980)]. Using this procedure for the Anderson tight-binding model in dimensions $d=2,3$, we study numerically the statistical properties of the renormalized on-site energies $ε$ and of the renormalized hoppings $V$ as a function of the linear size $L$. We find that the renormalized on-site energies $ε$ remain finite in the localized phase in $d=2,3$ and at criticality ($d=3$), with a finite density at $ε=0$ and a power-law decay $1/ε^2$ at large $| ε|$. For the renormalized hoppings in the localized phase, we find: ${\rm ln} V_L \simeq -\frac{L}{ξ_{loc}}+L^ωu$, where $ξ_{loc}$ is the localization length and $u$ a random variable of order one. The exponent $ω$ is the droplet exponent characterizing the strong disorder phase of the directed polymer in a random medium of dimension $1+(d-1)$, with $ω(d=2)=1/3$ and $ω(d=3) \simeq 0.24$. At criticality $(d=3)$, the statistics of renormalized hoppings $V$ is multifractal, in direct correspondence with the multifractality of individual eigenstates and of two-point transmissions. In particular, we measure $ρ_{typ}\simeq 1$ for the exponent governing the typical decay $\overline{{\rm ln} V_L} \simeq -ρ_{typ} {\rm ln}L$, in agreement with previous numerical measures of $α_{typ} =d+ρ_{typ} \simeq 4$ for the singularity spectrum $f(α)$ of individual eigenfunctions. We also present numerical results concerning critical surface properties.
