title: Analysis of HIV-1 specific antibodies induced by Ugandan viruses or virus encoded peptides
Creators: name: Smith, Jacqueline D
Publisher: name: The Open University
Year: 2005

description: The main objectives of the work presented in this thesis were to develop an assay to subtype viruses circulating in Uganda and to study virological and immunological factors that might be important in HIV-1 vaccine development in East Africa. Development of an antibody binding assay for serological subtyping revealed a complex pattern of cross-reactivity, and led to further investigation of these responses. Competitive inhibition and adsorption studies identified a spectrum of antibodies in the human antisera, possibly due to multiple immune responses to more than one viral epitope or to one immunodominant epitope. Neutralizing antibodies to specific V3 loop peptides were raised in rabbits; MN and U31 peptides were good immunogens, but Ugandan consensus sequence peptides raised antisera with weak peptide reactivities. Antibody binding assay of partial V3 loop peptides indicated that most Ugandan antisera recognised an epitope(s) in the C-terminal region of the V3 loop, not at the apex. Virus samples from the UVRI clinic and the Natural History cohort in rural SW Uganda were isolated and characterized. Comparison of primary isolates in PBMC cultures and cell adapted variants indicated that SI and NSI variants may be present within a primary isolation culture. Neutralizing antibody titres were compared between cell line adapted viruses and primary isolates: Differences found led to the use of low passaged primary isolates for this investigation. Cross-clade neutralizing antibodies were present in most antisera, many with high neutralization titres (>640); suggesting a shared immunogenic epitope, which could be important in vaccine design. Analysis of sequential serum samples revealed no decrease in neutralizing titres with time. One sequential virus isolate (3029), re-isolated after 2 years, was more resistant to neutralization by heterologous antisera. No correlation was established between antibody binding and neutralization by human or rabbit antisera. Comparison of clinical data with neutralization data was inconclusive.

description: Photodisintegration of polarized 3He by linearly or circularily polarized photons offers a rich choice of observables which can be calculated with high precision using a rigorous scheme of three-nucleon Faddeev equations. Using the (semi)phenomenological AV18 nucleon-nucleon potential combined with the Urbana IX three-nucleon force we investigate sensitivity of 3He photodisintegration observables to underlying currents taken in the form of a single-nucleon current supplemented by two-body contributions for $π$- and $ρ$-meson exchanges or incorporated by the Siegert theorem. Promising observables to be measured for two- and three-body fragmentation of 3He are identified. These observables form a challenging test ground for consistent forces and currents being under derivation within the framework of chiral perturbation theory. For thre-body 3He photodisintegration several kinematicaly complete configurations, including SST and FSI, are also discussed.

description: Surface acoustic waves (SAWs) can create moving quantum dots in piezoelectric materials. Here we show how electron-spin qubits located on dynamic quantum dots can be entangled. Previous theoretical and numerical models of quantum-dot entanglement generation have been insufficient to study quantum dynamics in realistic experimental devices. We utilize state-of-the-art graphics processing units to simulate the wave function dynamics of two electrons carried by a SAW through a 2D semiconductor heterostructure. We build a methodology to implement a power-of-SWAP gate via the Coulomb interaction. A benefit of the SAW architecture is that it provides a coherent way of transporting the qubits through an electrostatic potential. This architecture allows us to avoid problems associated with fast control pulses and guarantees operation consistency, providing an advantage over static qubits. For inter-dot barrier heights where the double occupation energy is sufficiently greater than the double-dot hopping energy, we find that parameters based on experiments in GaAs/AlGaAs heterostructures can produce a high-fidelity root-of-SWAP operation. Our results provide a methodology for a crucial component of dynamic-qubit quantum computing.

description: The properties of two forms of the gradient expanded Kadanoff--Baym equations, i.e. the Kadanoff--Baym and Botermans-Malfliet forms, suitable to describe the transport dynamics of particles and resonances with broad spectral widths, are discussed in context of conservation laws, the definition of a kinetic entropy and the possibility of numerical realization. Recent results on exact conservations of charge and energy-momentum within Kadanoff-Baym form of quantum kinetics based on local coupling schemes are extended to two cases relevant in many applications. These concern the interaction via a finite range potential, and, relevant in nuclear and hadron physics, e.g. for the pion--nucleon interaction, the case of derivative coupling.

description: USDA’s Economic Research Service (ERS) purchased proprietary household and retail scanner data from market research firm IRI for use in economic research. In a series of studies, ERS and collaborators evaluated the statistical properties of the IRI scanner data for the years 2008 to 2012. This report compares the IRI Consumer Network household panel data to nationally representative Government survey data and describes implications for using the IRI data in analyses. The results show that expenditures in IRI are lower than those in the Consumer Expenditure Survey (CE) and the National Food Acquisition and Purchase Survey (FoodAPS) for all food categories across all years.

description: Point interactions for the second derivative operator in one dimension are studied. Every operator from this family is described by the boundary conditions which include a $ 2 \times 2 $ real matrix with the unit determinant and a phase. The role of the phase parameter leading to unitary equivalent operators is discussed in the present paper. In particular it is shown that the phase parameter is not redundant (contrary to previous studies) if non stationary problems are concerned. It is proven that the phase parameter can be interpreted as the amplitude of a singular gauge field. Considering the few-body problem we extend the range of parameters for which the exact solution can be found using the Bethe Ansatz.

description: In this paper, we study the motion of test particles around two exact charged black-hole solutions in Einstein-Æther theory. Specifically, we first consider the quasi-periodic oscillations (QPOs) and their resonances generated by the particle moving in the Einstein-Æther black hole and then turn to study the periodic orbits of the massive particles. For QPOs, we drop the usually adopted assumptions $ν_U=ν_θ$, $ν_L=ν_r$, and $ν_U/ν_L=3/2$ with $ν_U$ ($ν_L$) and $ν_r$ ($ν_θ$) being the upper (lower) frequency of QPOs and radial (vertical) epicyclic frequency of the orbiting particles, respectively. Instead, we put-forward a new working ansatz for which the Keplerian radius is much closer to that of the innermost stable circular orbit and explore in detail the effects of the æther field on the frequencies of QPOs. We then realize good curves for the frequencies of QPOs, which fit to data of three microquasars very well by ignoring any effects of rotation and magnetic fields. The innermost stable circular orbits (isco) of timelike particles are also analyzed and we find the isco radius increases with increasing $c_{13}$ for the first type black hole while decreases with increasing $c_{14}$ for the second one. We also obtain several periodic orbits and find that they share similar taxonomy schemes as the periodic equatorial orbits in the Schwarzschild/Kerr metrics, in addition to exact solutions for certain choices of the Einstein-Æther parameters. The equations for null geodesics are also briefly considered, where we study circular photon orbits and bending angles for gravitational lensing.

Real space origin of temperature crossovers in supercooled liquids

description: We show that the various crossovers between dynamical regimes observed in experiments and simulations of supercooled liquids can be explained in simple terms from the existence and statistical properties of dynamical heterogeneities. We confirm that dynamic heterogeneity is responsible for the slowing down of glass formers at temperatures well above the dynamic singularity T_c predicted by mode coupling theory. Our results imply that activated processes govern the long-time dynamics even in the temperature regime where they are neglected by mode-coupling theory. We show that alternative interpretations based on topographic properties of the potential energy landscape are complicated and inefficient ways of describing simple physical features which are naturally accounted for within our approach. We show in particular that the reported links between mode coupling and landscape singularities do not exist.

description: Americans spend about half of their food budgets to purchase about two-thirds of their food from stores. USDA purchases retail and household scanner data for food and economic research covering a broad range of Federal food and nutrition topics that relate to these foodat- home purchases. Although the data contain some nutrient data, they are not sufficient to measure how well Americans follow dietary advice or what may motivate them to do so. USDA compiles extensive nutrient and food group databases to support dietary intake studies including the National Health and Nutrition Examination Survey (NHANES). In this study, we use probabilistic and semantic matching techniques to merge the scanner data with the USDA nutrient and food composition databases. As an illustration, we use the new purchase-to-plate “crosswalk”—consisting of matches and conversion factors—to estimate the overall nutritional quality of Americans’ food-at-home purchases. The 2015 Healthy Eating Index (HEI-2015) score for 2013 retail scanner sales is 55 out of 100, indicating that Americans need to substantially improve the healthfulness of their grocery purchases if they wish to follow the Federal Government’s Dietary Guidelines for Americans.
title: The Influence of Switzerland on the Life and Writings of Edward Gibbon
Creators: name: Norman, Brian
Publisher: name: The Open University
Year: 1999

description: The purpose of this thesis is to demonstrate, through close examination of Gibbon’s lesser writings, in addition to his well-known works, the importance of Switzerland in his life and thinking. The texts used for this study are his Journal de mon voyage, written at the age of eighteen in 1755, his Letter on the Government of Berne, which is established here as a composition of the 1750’s, his Essai sur l'Étude de la Littérature, the Journals which cover the years up to his tour of Italy in 1764, the topographical survey of classical Italy entitled Nomina, gentesque antiquae Italiae, and his Introduction à l'Histoire Générale de la République des Suisses, with reference throughout to The Decline and Fall of the Roman Empire, the Memoirs and his Letters.

 It was in Lausanne that he completed his education, began his first published work, the Essai, and entered into a society which was close to the centre of “The Enlightenment”, enlivened as it was by the presence of Voltaire. Switzerland remained persistently in Gibbon’s thoughts after his return to England in 1758; its society caused him to reside in Lausanne eleven months while he prepared for his tour of Italy in 1763/4; and the origins and evolution of Switzerland continued to be his preferred subject for his historical writings until 1767. Later, Lausanne offered him the society and historical resources which he desired when completing the last three volumes of his major work.

 The main findings of this study establish Switzerland as a major influence on his feelings for liberty, independence and industry; the example of its communal assemblies and commitment to military preparedness formed an essential political reference in the historical judgements in The Decline and Fall of the Roman Empire. As a result of his experience of Switzerland, Gibbon is more aware of the value of a free peasantry, and he applauds the benefits of industry and commerce to the community as a whole.

description: We explore a scenario where metal-poor globular clusters (GCs) are enriched by the first supernovae in the Universe. If the first stars in a 10^7 Msun dark halo were very massive (>180 Msun), then a pair instability supernova from a single massive star can produce sufficient iron to enrich 10^6 Msun of pristine, primordial gas to [Fe/H] ~ -2. In such a scenario, where a single massive star acts as a seed for halo GCs, the accurate abundance analysis of GC stars would allow a direct measurement of the Population III initial mass. Using the latest theoretical yields for zero metallicity stars in the mass range 140-260 Msun, we find that the metals expelled from a ~230 Msun star are consistent with [Si/Fe] and [Ca/Fe] observed in GC stars. However, no single star in this mass range can simultaneously explain all halo GC heavy-element abundance ratios, such as [V/Fe], [Ti/Fe] and [Ni/Fe]. These require a combination masses for the Population III stellar progenitors. The various observational consequences of this scenario are discussed.

description: Since 2003, the American Time Use Survey (ATUS) has collected detailed information about how Americans spend their time by asking respondents to identify primary or main activities they were engaged in over a full 24-hour period, including eating. This means that the ATUS misses “secondary” eating occasions that occur while an individual is otherwise occupied doing something else that is considered to be primary, such as working or watching TV. The Eating & Health Module (EHM) was designed to collect these secondary eating occasions and was included as a supplement to the ATUS during 2006-08 and again in 2014-16. This report compares the number and timing of eating occasions reported in the 2014-16 ATUS-EHM to those reported in the dietary intake component of the 2013-16 National Health and Nutrition Examination Survey (NHANES), which is considered to contain the best available data for estimating average daily dietary intake among the U.S. population. Findings show that the EHM reduces the gap between the ATUS and NHANES with respect to the total number of eating occasions during the day, as well as the share of people reporting eating during each hour of the day, but overall the ATUS-EHM does not capture as many eating occasions as NHANES. When the analysis excludes more easily forgotten eating occasions—that is, drinks and snacks—from the NHANES data, the ATUS-EHM data capture 93.1 percent of all eating occasions reported in NHANES.

description: In the contemporary age of big data and sharing intelligence, tourism market has constantly changing scenario thanks to the unceasing communication technologies’ revolution. According to this growth perspective, cultural heritage tourism is increasing his offer quality standards, by giving evidence of its social and territorial identity value. In light of this, the research is focused on the study of hospitality places located along the Vie ROMEE maiores (Via Francigena, Via Romea Strata and Via Romea Germanica), the most famous slow tourism product in Italy, that has recently been promoted in such original ways. In particular, the paper describes the touristic system of San Pellegrino in Alpe, a village located on the Tuscan and Emilian Via Francigena route, with the final aim to suggest a touristic renovation model in light of the current Covid-19 changing scenario. Therefore, the research study shows how local stakeholders are able to foster territorial promotion activities, both for residents and for tourists, in order to empower local tourism system and local community awareness. In this context, the new marketing tools for virtual tourism, videomaking and crowdfunding play a strategic role for local tourism development; especially when they are used by stakeholders, such as Film Commissions and small local museums to assure a better quality of life in sustainable tourism destinations.

description: We show that a quantum field theory A living on the line and having a group G of inner symmetries gives rise to a category GLoc A of twisted representations. This category is a braided crossed G-category in the sense of Turaev. Its degree zero subcategory is braided and equivalent to the usual representation category Rep A. Combining this with [29], where Rep A was proven to be modular for a nice class of rational conformal models, and with the construction of invariants of G-manifolds in [60], we obtain an equivariant version of the following chain of constructions: Rational CFT -> modular category -> 3-manifold invariant. We then study the relation between GLoc A and the braided (in the usual sense) representation category Rep A^G of the orbifold theory A^G. We prove the equivalence Rep A^G = (GLoc A)^G, which is a rigorous implementation of the insight that one needs to take the twisted representations of A into account in order to determine Rep A^G. In the opposite direction we have GLoc A = Rep A^G \rtimes S, where S \subset Rep A^G is the full subcategory of representations of A^G contained in the vacuum representation of A, and \rtimes refers to the Galois extensions of braided tensor categories of [44,48]. If A is completely rational and G is finite we prove that A has g-twisted representations for every g in G. In the holomorphic case (where Rep A = Vect_C) this allows to classify the possible categories GLoc A and to clarify the role of the twisted quantum doubles D^ω(G) in this context, as will be done in a sequel. We conclude with some remarks on non-holomorphic orbifolds and surprising counterexamples concerning permutation orbifolds.

description: Accurate and detailed prices are a key component to analyze a variety of important questions related to consumer behavior. Given the importance of food-away-from-home (FAFH) consumption in a typical American’s diet, the variation in nutritional value across different types of FAFH meals, and evidence that prices may vary substantially across areas, Economic Research Service researchers created a novel dataset that can be used to study how prices may affect food choices, intake, and health outcomes. The Quarterly Food-Away-from-Home Prices (QFAFHP) data contain quarterly average prices without tax for meals and specific FAFH (e.g., all entrees and combination meals, soda, hamburgers, school lunches) from four types of FAFH establishments (full- and limitedservice restaurants, vending machines, and schools) and for alcoholic beverages (at home and away from home). The prices are further disaggregated for the entire Nation, four census regions, and nine census divisions. ERS developed QFAFHP as a complementary data product to the Quarterly Food-at-Home Price Database, which provides market-level food prices for food-at-home products based on the Nielsen Homescan data. This report describes in detail the methodology behind QFAFHP and the underlying data, composed of individual product prices collected by the Bureau of Labor Statistics for the Consumer Price Index.

We detect dust signatures in 39 SNRs out of 190, made up of 13 core-collapse supernovae (CCSNe), including 4 Pulsar Wind Nebulae (PWNe), and 2 Type Ia SNe. A further 24 FIR detected SNRs have unknown types. We confirm the FIR detection of ejecta dust within G350.1-0.3, adding to the known sample of ~10 SNRs containing ejecta dust. We discover dust features at the location of a radio core at the centre of G351.2+0.1, indicating FIR emission coincident with a possible Crab-like compact object, with dust temperature and mass of Td = 45.8 K and Md = 0.18 solar mass, similar to the PWN G54.1+0.3. We show that the detection rate is higher among young SNRs. We produce dust temperature maps of 11 SNRs and mass maps of those with distance estimates, finding dust at temperatures 15 < Td < 40 K. If the dust is heated by shock interactions the shocked gas must be relatively cool and/or have a low density to explain the observed low grain temperatures.

This study evaluates the extent to which retailers exercise market power in buying from growers and selling to consumers. Sales data for retail chains in six U.S. metropolitan markets are used along with data on grower prices for an analysis on apples, grapes, oranges, and grapefruit. The evidence varies by commodity, but does consistently point to the exercise of market power by retailers in consumer sales; less support is found on buying market power. Market power varies over time and with produce volume.

In this paper we study CP violation in $B_d^0$ and $B_s^0$, which is induced by the tau-neutrino Yukawa coupling. In particular, we notice the correlation of the CP asymmetries in $B_d^0\to ϕK_s$ ($S_{ϕK_s}$) and $B_s^0\to J/ψϕ$ ($S_{J/ψϕ}$) with other observables, such as $Br(τ\toμγ)$, the muon EDM ($d_μ$), and the mixing-induced CP asymmetry in $B_d^0\to M_s^0γ$ ($A_{bsg}$), since they have a common origin of the CP and flavor violation. The measurements are expected to play a significant role for consistency check of the SUSY SU(5) GUT. The hierarchical right-handed neutrino masses make the correlation better. We find that the current bound on $Br(τ\toμγ)$ constrains the allowed region for $S_{ϕK_s}$ in this model.

description: The pandemic has strongly marked the Italian territory and had had consequences in the healthy sphere, as it is clear, and also in the social and economic fabric of the countries. The lockdown, the adoption of health safety measures and the closure of borders had immediate consequences in economies and territories. Thus, the health emergency became also a tourism and socio-economic issue. In particular, in Italy, tourism has been one of the pillars of the economic system, and certainly the impact of COVID-19 on the national tourism market has been dramatic. The tourism crisis highlighted some of the rooted tourist issues in Italy, involving, in particular, the tourist management of territories. In order to restart the design of a healthy tourism system, capable of promoting the survival of tourism and territories, had to be considered as necessary elements to restart Italian tourism such as the role of high education for quality tourism, the design of a hybrid offer to favor the development of domestic tourism and the exploration of the digital and technological field as a support tool for territorial, tourism and communication policies.

title: Teamworking in Two Dissimilar Secondary Comprehensive Schools: An Account of Team Roles, Interaction and interdependence in Action
Creators: name: Asong, Sophina Besong

Year: 2005

description: This study investigates team working in four middle level teams within two socio economically and geographically dissimilar secondary comprehensives. Over a period of two years, data was collected using Belbin’s (1993) Self-Perception Inventory, administered to a total of thirty eight teachers at various levels of responsibility within the two schools. The response rate was 91.9%. A total of twelve team meetings were observed, videoed and analysed using Bales’ (1950) Interaction Process Analysis schedule. The result is a descriptive account of how teachers and their leaders deploy their roles and interact as they work together in teams.

 This study found that, although school cultures assumed that teachers would work in a team structure, both teachers and their leaders seemed either not to have a conceptual understanding of their team roles, or considered it unimportant in the pursuance of their day to day work. Interactions in meetings did not always reflect teachers’ self-perceived team roles, and interdependence tended to be predominantly task-focussed. The study revealed that the quality and extent of teamworking was problematic in many respects. The practice of teamworking in the school contexts studied showed gaps between the prescription and advice proffered by management literature, and the reality of teamworking in key areas of team management such as leadership, goal management, vision making and conflict recognition/resolution.
Plants Alive : Representations of the 19th Century Herbaceous Drift
Creators: name: Gooch, Hailey
Publisher: name: The University of British Columbia

description: Since the Renaissance, images have been powerful instruments that have shaped perceptions of landscape. These representations of ‘nature’ through the image have inflicted an anthropocentric (human-centered) language onto the innate aliveness of plant life. This project highlights the dynamic expression of plants through drawing and seeks to understand how the depiction of a plant informs its use in the landscape. The representation of the plant as a static symbol impacts how we see phenomena that shifts, swarms, coevolves, and ultimately hosts human life. Through interpretations of Gertrude Jekyll’s herbaceous perennial drift, this project illustrates the aliveness of plants and asks how the plant can have agency through drawing. Can we collaborate with the language of plants, rather than speak on behalf of them? Can we ‘re-see’ the plant in the design discipline, and if so, how will this inform design decisions?
The Collective Traumatic Event of COVID-19 Pandemic and its Psychological Impact on Beliefs and Intentions of Senior Italian Tourists

description: Introduction. The COVID-19 Pandemic represents a traumatic collective event that has suddenly modified our future perception, representation and our lifestyle, including travel for tourism. Tourism is one of the major economic sectors that is suffering from it. Objectives, Method and Procedures. The study analyzed, through a purpose-built online questionnaire, in a sample of 311 Italian old people (m. age = 69.70) how much they believe that COVID-19 Pandemic will change their way of going on holidays. The possible perceived obstacles to continue to travel for tourism in and after Covid-19 Pandemic, and the beliefs about the relevance of tourism in general and cultural tourism for old people and the intention to continue the travel experience in the future are being effected. Results. Old people believe that this pandemic will change their way to go on holidays, and this belief is more pronounced for female than for males; the most critical obstacles are anxiety and fear about a sudden return of Coronavirus, the lack of safety systems in tourism hospitality structures, the lack of effective instruments by Tour Operators for dealing with Coronavirus in the touristic destinations, with 18% of explained variance. On the contrary, they possess very positive beliefs about the relevance of tourism in general and cultural tourism as a specific form of travel.

description: We review a range of stastistical methods for analyzing the structures of star clusters, and derive a new measure ${\cal Q}$ which both quantifies, and distinguishes between, a (relatively smooth) large-scale radial density gradient and multi-scale (fractal) sub-clustering. Q is derived from the normalised correlation length and the normalised edge length of the minimal spanning tree for each cluster.
From Epidemics to Pandemic: Tips from the Past

description: The World Tourism Organization proposed to examine studies on previous infectious disease outbreaks (epidemics), in particular the severe acute respiratory syndrome (SARS) epidemic of 2002–2004, to better managing the impact of the COVID-19 on the tourism industry. We followed this suggestion by analysing tourism-related literature concerning previous outbreaks. We consequently identified the differences and similarities between past epidemics and the COVID-19 pandemic, evaluated recovery strategies previously adopted by tourism destinations, and suggested a research agenda to facilitate the tourism destinations’ recovery. To provide theoretically grounded research suggestions, which are urgently needed by the tourism industry, only contributions from high-quality peer-reviewed journals were considered in this literature review.

Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.The present study examines statistically the general validity of a set of hypotheses regarding long-term changes in the relationship between recruitment, spawning stock and temperature in commercially harvested fish stocks, Disentangling the effects of climate variability and internal population dynamics on recruitment by means of statistical data analysis is no easy task. It can, however, be facilitated by using long time series on many stocks in comparative analyses, an approach particularly insightful to explore the mechanisms linking climate and their ecosystem responses. Here a comparative approach is employed in statistically modeling temporal changes in recruitment dynamics in 42 commercially harvested fish stocks, mainly gadoids and clupeids, in the northern North Atlantic (Table 1)
title: Quality management: an 'essential attributes' approach. A case study towards a sustainable model of course effectiveness evaluation
Creators: name: Murphy, Francis Spenser
Publisher: name: The Open University
Year: 2005

description: An education programme for mechanical engineers should ensure that graduates have a number of 'essential attributes' (high level of mathematical ability, teamwork skills, creativity, etc.) for them to adequately function as professional engineers. This research examines a case study of the BEng (Mechanical Engineering) at Cork Institute of Technology, Ireland. The delivery of essential attributes are proposed as criteria for the measurement of educational effectiveness. From a review of literature concerning organisational/educational effectiveness, the concepts of 'microquality' and 'macroquality' are developed. Redefining these concepts, facilitates an examination of the case study (microquality) in determining 'fitness for purpose' and the wider debate on engineering higher education (macroquality) in determining 'standards of excellence'. The BEng course is compared with both 'fitness for purpose' and 'excellence'. Gathering of data utilises qualitative interviews of stakeholders, documentation analysis and some workplace observation. Data analysis of interviews, course and wider debate documentation is undertaken using QSR NUD*IST version 4 software. Following preliminary data gathering, theory building produces an engineering concept of excellence (a sustainable world). A causal model is developed with this concept as the aim, which links standards of excellence, essential attributes, educational factors, student intelligences, learning theories and staff training. Modifying this model by including the influences of documentation and interviews, leads to a model of course effectiveness evaluation, which is offered as a method suitable for other courses. This model extends existing employability theory by providing it with an alternative structure. The case study examines the BEng course for 'fitness for purpose' and 'excellence'. Improvements are recommended in both cases. The core stakeholder group (graduates and students), are found to have provided standards of excellence with the most impact on the engineering concept of excellence and course sustainability. The wider debate documentation does not have as much impact as originally thought. The core stakeholder group appears to be demanding excellence from the course and not just fitness for purpose. It will be interesting to see if this is the case for other disciplines.

description: Many times we have observed some points that microbes and micro-bubbles go towards them and disappear and after a time, some new microbes or micro-bubbles appear. This may be an effect of micro-gravity only not more. Because, by reducing size of objects, gravitational effects become more appeared. However, we shouldnt disregard another probability so. Maybe, space-time have changed in those points and some gravitational objects like micro-wormholes appear. These micro-wormholes (only an assumption) could move and arent limitted to events under microscope. Maybe, they appeared under our microscope by chance. The question arises that why we couldnt see these objects under microscope? Maybe response be that these aren't objects but only some changes in space-time which absorb light and no light is emitted by them such as we could only observe their effects like motions and disappearing microbes within them. Although, this is only a theory and we should obtain more reasons and consider more. This film is one of our observations. Although, unfortunately, until now, we have ignored these facts and not take any video of previous events. We have no any claim yet and only propose a proposal for scientific communities.
