description: In this chapter, we intend to present the map making state-of-the-art and discuss current and future prospects for the development of an automated methodology for map aggregation that takes into account the need for integration of mobility data and the social networking trend, which we believe will eventually become the main source of geographical maps. This will allow us to abstract a general architecture for a Collaborative Map Generation System and discuss in some detail the technical challenges for each module (and its current solutions). In doing so, we hope to show that as a very relevant and desirable ‘side effect’, a set of algorithms must be developed that will help with regard to those Transport and Urban management tasks referred to above. We address filtering, map matching, update and aggregation, steps for the construction of the maps, and some efficient algorithms and data structures that are used to compress, process and query the map once generated.

Char particle reaction and attrition in fluidized bed combustors: Modelling and measurement.
Creators: name: Lau, Ivan T.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1995
Subjects: subject: Engineering, Chemical.

description: Two slightly different models for predicting combustion efficiency for burning coal chars in bubbling fluidized bed combustors are developed. The models proposed assume that char particles are consumed simultaneously by combustion reaction and attrition with the rates of both processes following the shrinking particle model. To solve the gas-solid reaction problem, an approach quite different from the traditional method has been attempted. Characteristic times are introduced based on mean residence time concepts to characterize the reaction and attrition kinetics and particle size of different groups of char particles (ie original, attriated, elutriated, and withdrawal particles). Based on fundamental material balances and the proposed reaction-attrition mechanism, the models link combustion efficiency to some measurable parameters, including a few of the introduced characteristic times. Experimental techniques employing two types of batch experiments to determine the model parameters were developed. The first type experiments involve burning char particles to completion, while the second type experiments involve freezing the char combustion reaction, separating attrited particles from the original mother chars, and subsequently burning off attrited fines. With experimental records of exit gas concentrations of carbon oxides vs time for first type experiments as input, the models can be used to evaluate the parameters which characterize the reaction of burning char particles. When similar records for second type experiments are used, other parameters characterizing the attrited and elutriated particles can be obtained. The method also allows carbon losses from both types of experiments to be estimated. The new developments give a way to estimate the attrition rate and the elutriation fraction of post-attrition combustion char fines in fluidized beds, problems not previously solved. Experiments were performed with a bench-scale fluidized bed combustor to demonstrate the model parameter measuring techniques and to test the model features. The results show that the measured parameters are within reasonable ranges and generally agree well with the model assumptions. On the other hand, probably due to secondary fragmentation effects and the difficulty of precise burnout time measurement, most results evaluated for the power of dependence of fractional conversion on time are lower than expected, and discrepancies exist between the results of carbon loss estimated from the two types of experiments. The influences of coal type and operating conditions on the model parameters are also investigated. The results shown generally agree with past experience and are interpreted with the proposed model of the reaction-attrition mechanism.
Approaches for handling software version mismatch in data communication networks.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1994
Subjects: subject: Computer Science.

description: This thesis studies restrictive interoperability between distinct versions of implementations based on standards or recommendations. Successful interoperability between two communicating versions on different networks depends upon: (1) how accurately the versions were derived from the standard, and, (2) how similar were the selection of supported options in the distinct versions, and (3) how familiar were the respective network managers about the functional differences between the two versions before provisioning and the start of commercial operation. Each network has a complex architecture to support numerous applications installed on a broad range of different hardware platforms. Applications are designed to be accessed by local users or public network subscribers. Attempts made by users/subscribers to access a service from a remote application in order to carry out an end-to-end function over one or more than one distinct network may fail because of: (1) functional limitations of the protocol stacks beneath the target application, or (2) functional limitations in the services or options offered by an intermediary network. In this thesis, we relate possible causes and give possible methods for prevention and recovery within two primary development and operational mechanisms: (1) The standards development process. (2) Network management methods. (Abstract shortened by UMI.)
Two-dimensional depth-averaged phytoplankton growth modelling in the Rideau River (Black Rapids-Hog's Back reach)

Subjects: subject: Engineering, Civil.

description: The present study was carried out to model the algal growth in Black Rapids-Hog's Back reach of the Rideau River. In this study a two-dimensional depth-averaged hydrodynamic model (HYDROSIM) and a transport model (DISPERSIM) both packaged in a GUI called MODELEUR were used. The model has been developed by Scientific Research Institute (INRS-EAU), Quebec. A model for growth and transport of algae was developed which was incorporated in the existing transport model, DISPERSIM. The simulated results of velocity vectors from HYDROSIM showed an agreement with the Acoustic Flowmeter For Remote Areas (AFFRA) measurements although the simulated values were always on the lower side. The modelling results of MIKE3D and a study carried out in 1997 support the results of the flow modelling in the present study. (Abstract shortened by UMI.)

description: The chromatin remodeling protein alpha thalassemia/mental retardation syndrome X-linked (ATRX) is a component of promyelocytic leukemia nuclear bodies (PML-NBs) and thereby mediates intrinsic immunity against several viruses including human cytomegalovirus (HCMV). As a consequence, viruses have evolved different mechanisms to antagonize ATRX, such as displacement from PML-NBs or degradation. Here, we show that depletion of ATRX results in an overall impaired antiviral state by decreasing transcription and subsequent secretion of type I IFNs, which is followed by reduced expression of interferon-stimulated genes (ISGs). ATRX interacts with the transcription factor interferon regulatory factor 3 (IRF3) and associates with the IFN-β promoter to facilitate transcription. Furthermore, whole transcriptome sequencing revealed that ATRX is required for efficient IFN-induced expression of a distinct set of ISGs. Mechanistically, we found that ATRX positively modulates chromatin accessibility specifically upon IFN signaling, thereby affecting promoter regions with recognition motifs for AP-1 family transcription factors. In summary, our study uncovers a novel co-activating function of the chromatin remodeling factor ATRX in innate immunity that regulates chromatin accessibility and subsequent transcription of interferons and ISGs. Consequently, ATRX antagonization by viral proteins and ATRX mutations in tumors represent important strategies to broadly compromise both intrinsic and innate immune responses.

From 'special experiment' to state specialist language school: the Victorian School of Languages 1935 - 2015
Creators: name: Bryant, Catherine
Publisher: name: Swinburne
Year: 2024

description: This thesis is a historical investigation of the Victorian School of Languages (VSL), which is a 'complementary provider' of language education. It is 'both a story and a study' and it utilises a combined research methodology of historical analysis and theory. It draws extensively on primary sources such as archival documents and oral history. It presents a chronological narrative and an analysis of the origins, the growth and the development of the VSL. It uses several theoretical lenses to investigate the way that this non-conformist school and its subject communities gained and maintained legitimacy in the Victorian education system.
Data extraction from the Web using XML.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2001
Subjects: subject: Information Science.

description: This thesis presents a mechanism based on eXtensible Markup Language (XML) to extract data from HTML-based Web pages and populate relational databases. This task is performed by a system called the XML-based Web Agent (XWA). The data extraction is done in three phases. First, the Web pages are converted to well-formed XML documents to facilitate their processing. Second, the data is extracted from the well-formed XML documents and formatted into valid XML documents. Finally, the valid XML documents are mapped into tables to be stored in a relational database. To extract specific data from the Web, the XWA requires information about the Web pages from which to extract the data, the location of the data within the Web pages, and how the extracted data should be formatted. This information is stored in Web Site Ontologies which are built using a language called the Web Ontology Description Language (WONDEL). WONDEL is based on XML and XML Pointer Language. It has been defined as a part of this work to allow users to specify the data they want, and let the XWA work offline to extract it and store it in a database. This has the advantage of saving users the time waiting for the Web pages to download, and taking benefit from the powerful query mechanism offered by database management systems.
Tracking Down the Effects of Travel Demand Policies

Year: 2008

description: This chapter addresses two issues related to tracking people through mobile technologies and spatial planning decisions. The first major part deals with the question of how knowledge developed through the use of new tracking technologies can impact the spatial planning process. We argue that global positioning system (GPS) data are valuable – if not vital – for the improvement of travel demand forecasts by means of an activity-based transportation model when assessing travel demand management (TDM) policies such as spatial planning strategies. Based on a brief historical outline with regard to planning policies and an overview of various travel demand models, the need for advanced data and their use in modelling practice is shown. In the next section, the other topic of this chapter discusses what kind of spatial interventions can be expected due to the use of new tracking technologies. Here, four application areas related to travel demand modelling are identified and subsequently explained: the use of route knowledge and the concepts of accessibility, activity spaces and mental maps.

A Method for Deriving Trip Destinations and Modes for GPS-based Travel Surveys

Publisher: name: Research in Urbanism Series
Year: 2008

description: This chapter contributes to the improvement of GPS-based travel surveying by introducing a combined method of GPS, GIS and web-based user interaction, which has been applied in large- scale fieldwork in the netherlands. With over 1000 participants, as far as we know, this is the first time that a GPS-based method that measures travel mode choice as well as the location and type of destinations that are visited has been used on such a large scale. The chapter focuses in particular on the identification of travel modes and destinations, which is still an under-researched issue. Our approach concentrates on the issue of deriving and validating the purpose of trip destinations and travel modes, while also allowing reliable multi-day data collection. The method consists of an interpretation process and a validation process. The interpretation process uses spatial data (e.g. railways, shops) and characteristics of the respondents (e.g. home address, possession of cars) to interpret data from the logs. The travel behaviour data that result from this interpretation round can be adjusted and added to by the respondents in a validation application. The link between both processes is interactive; when new individual characteristics (e.g. the address of a friend’s house) are entered by the respondents, these characteristics will be used for further interpretation of the data. The remainder of this chapter is structured as follows. The following section gives an overview of the advantages and drawbacks of current GPS-based data collection methods that are suitable for measuring choice of travel mode and/or trip destinations. The subsequent section describes the GPS-based method that we developed and in section four the value of our method is evaluated by presenting the results of the fieldwork we recently undertook. The results are compared with results from an internet survey that was carried out at an earlier date and also with the Dutch Travel Survey (DTS) that uses paper diaries. The chapter ends with conclusions on the use of GPS-based methods for the collection of travel behaviour data and a discussion of future possibilities.

description: Various applications of geo-referenced information currently being developed are or will be both commercially and publicly available. These applications combine functions such as mobile communication, GPS, digital photography, e-mail, cartography, satellite imaging and internet access. One of the first applications of so-called ‘location based services (LBS)’ has been the tracking & tracing of convicts on parole and animal species in the wild. In the United States, web-based products are available that enable parents to trace the whereabouts of their children, so-called child monitoring services. Locative media are also a powerful tool in the hands of urban investigators wishing to learn directly from users the specific routes they take and the locations or events they attend. Locative media can help to unveil the specific mental maps that an individual user has in his or her head. The experience and perception of a place or route can be reported by residents by means of short texts and photos. We decided to further develop geographical research techniques such as Hägerstrand’s space-time path and diary analysis. In doing so we developed sense of the city as a method of providing insight into the simultaneous but diverse patterns and experiences of people in regard to time and space.

description: Antenna layout is an important design consideration for radio interferometers because it determines the quality of the snapshot point spread function (PSF, or array beam). This is particularly true for experiments targeting the 21-cm Epoch of Reionization signal as the quality of the foreground subtraction depends directly on the spatial dynamic range and thus the smoothness of the baseline distribution. Nearly all sites have constraints on where antennas can be placed - even at the remote Australian location of the Murchison Widefield Array (MWA) there are rock outcrops, flood zones, heritages areas, emergency runways and trees. These exclusion areas can introduce spatial structure into the baseline distribution that enhances the PSF sidelobes and reduces the angular dynamic range. In this paper we present a new method of constrained antenna placement that reduces the spatial structure in the baseline distribution. This method not only outperforms random placement algorithms that avoid exclusion zones, but surprisingly outperforms random placement algorithms without constraints to provide what we believe are the smoothest constrained baseline distributions developed to date. We use our new algorithm to determine antenna placements for the originally planned MWA, and present the antenna locations, baseline distribution and snapshot PSF for this array choice.
Mobile Surveys

description: In recent years, a new approach for estimating people’s movement in cities has emerged through mobile phone positioning. As opposed to the more traditional methods of traffic surveys, automated counts, or individual counters on streets, the use of aggregated and anonymous cellular network log files has shown promise for large-scale surveys with notably smaller efforts and costs. In addition, a frequent data feed from the cellular network has also been argued to demonstrate fine grain over-time variation in urban movements, which are lacking from the traditional prediction methods. However, despite the positivist approach to the new methodology, additional evidence is needed to show how cellular network signals correlate with the actual presence of vehicles and pedestrians in the city. The purpose of this paper is to address this shortcoming by presenting the results of a survey effectuated in Rome, Italy in January 2007. Using the results of the two-day experiment, we will employ statistical models to investigate the relationship between empirical pedestrian and traffic counts on the streets of rome with the simultaneous Telecom Italia Mobile (TIM) network signal and traffic prediction. Secondly, we will explore whether the mobile network data demonstrates the significant time-dependent variation that is missing from traditional fixed predictors like space syntax choice and integration analysis and could thus describe cities dynamically over time. Finally, we will also outline some general issues of accuracy in using aggregate mobile network data for estimating people’s movement in cities.

description: Although there is consistent evidence of an inverse association between physical activity and colorectal cancer (CRC), it is unclear whether physical activity has to be lifelong in order to protect against CRC, or whether there are critical time periods in which physical activity is most protective. This thesis investigated the association between recreational physical activities in specific age periods and across the lifetime and CRC risk in data from a population-based case control study (n=1395) in Newfoundland and Labrador. There were no significant associations between recreational physical activity at any age period or across the lifetime. Lack of association with activity in early adulthood is consistent with other studies in which this has been investigated. Lack of association in later life and across the lifetime may in part be explained by low levels of recreational physical activity, with only 30% of participants meeting World Cancer Research Fund cancer prevention recommendations.
Compass routing on geometric graphs.

Subjects: subject: Computer Science.

description: In this thesis, we introduce a novel routing algorithm which we call "compass routing" to find paths between pairs of points in planar geometric graphs. Our main goal was that of developing, whenever possible, routing algorithms that, using only "local information", the position of our destination and a finite amount of extra memory, find a path from a starting position to our destination. We developed "compass routing" based routing algorithms for trees, Delaunay triangulations and orthogonal convexly embedded geometric graphs. Several related results on various types of geometric graphs were also studied.
Sharing in networked culture: imagination, labour and desire

description: Sharing is an important form of communication, and one that is championed in contemporary digital culture. This research asks what is sharing, and what roles do our digital devices and the platforms we use play in these practices?

Sharing is more complex and problematic than first perceived. There are tensions especially when sharing occurs through digital devices and platforms such as Facebook and Twitter. This work helps us understand what people do in relation to media and the significance of media in our daily lives.

Most importantly, it contributes a significant development in how sharing can be theorised by providing a new conceptual model that acknowledges the role of digital media.
Volumes of Hyperbolic Three-Manifolds Associated with Modular Links

Publisher: name: Multidisciplinary Digital Publishing Institute
Year: 2019

description: Periodic geodesics on the modular surface correspond to periodic orbits of the geodesic flow in its unit tangent bundle PSL₂(ℤ)\PSL₂(ℝ). A finite collection of such orbits is a collection of disjoint closed curves in a 3-manifold, in other words a link. The complement of those links is always a hyperbolic 3-manifold, and hence has a well-defined volume. We present strong numerical evidence that, in the case of the set of geodesics corresponding to the ideal class group of a real quadratic field, the volume has linear asymptotics in terms of the total length of the geodesics. This is not the case for general sets of geodesics.
Spatial Metro
Creators: name: Van Der Spek, Stefan
Publisher: name: Research in Urbanism Series
Year: 2008

description: This chapter describes the results of a series of pedestrian observation studies carried out in Norwich, Rouen and Koblenz as part of the Spatial Metro project. The goal of these studies was to observe pedestrian behaviour and to investigate pedestrian movement and experience in the city centres. The cities are engaged in improving the physical conditions and the experience of their city centres by investing in landscaping and engineering of public spaces, city beautification, wayfinding and in communication and information technology. The Spatial Metro project brings together a transnational group of partners, enabling them to co-operate with a view to improving city centres for pedestrians. The theme of spatial metro is 'Discovering the city on Foot'. The project aims to make city visits more enjoyable for pedestrians by making them easier to navigate, easier to walk around and easier to understand and appreciate. The project has been allocated European Regional Development Funding through the INTERREG IIIB Community Initiative. A group of ten organizations participate in Spatial Metro: The lead city of Norwich (UK) and the cities of Rouen (F), Koblenz (D), Bristol (UK), Biel/Bienne (CH), as well as academics from the University of East Anglia (UK), the Delft University of Technology (NL), the University of Koblenz (D) and the Swiss Pedestrian Association. The main role of the chair of Urban Design was to develop instruments to evaluate visitor experience and to observe the use of public space. The purpose of the observation studies was to evaluate the use of space in relation to investments, (rather than using the outcome as a design tool to pinpoint) opportunities and threads in the city; the outcome focuses on a comparison between the actual situation and real use. For the observation of the public space, a specific method using Global Positioning System (GPS) devices capturing the movement of pedestrians was developed and put into practice. The recording of pedestrian behaviour was accompanied by a questionnaire adding background information on the participants. This article will focus on the differences and similarities in pedestrian behaviour in three historic cities in three countries based on quantitative and qualitative research. Do people behave different in these three historic European cities? Can we distinguish different spatial patterns based on the origin and familiarity of the visitor and the purpose and duration of the visit? After this introduction, the set-up and implementation of the fieldwork will be explained in 'Way of Working'. Here, the methods for processing the data and the criteria employed in connection with the analysis will be clarified. Following this, the results will be described and illustrations provided for each location. The chapter concludes with a synthesis comparing the findings of the different cities.

Image segment processing for analysis and visualization

Subjects: subject: Computer Science.

description: This thesis is a study of the probabilistic relationship between objects in an image and image appearance. We give a hierarchical, probabilistic criterion for the Bayesian segmentation of photographic images. We validate the segmentation against the Berkeley Segmentation Data Set, where human subjects were asked to partition digital images into segments each representing a 'distinguished thing'. We show that there exists a strong dependency between the hierarchical segmentation criterion, based on our assumptions about the visual appearance of objects, and the distribution of ground truth data. That is, if two pixels have similar visual properties then they will often have the same ground truth state. Segmentation accuracy is quantified by measuring the information cross-entropy between the ground truth probability distribution and an estimate obtained from the segmentation. We consider the proposed method for estimating joint ground truth probability to be an important tool for future image analysis and visualization work.

description: La didattica dell’ascolto rappresenta uno strumento essenziale per condurre i discenti alla conoscenza e alla comprensione della musica occidentale e delle musiche di altre culture. Affinché sia ben condotta, la didattica dell’ascolto esige però che il docente possieda una perfetta padronanza del sapere sapiente e un’altrettanto spiccata capacità di cogliere le difficoltà insite nei processi di trasposizione del sapere. Tali difficoltà cambiano a seconda dei brani che di volta in volta vengono presi in considerazione. Questo contributo si concentra su alcune strategie di trasposizione didattica per composizioni dotate di un testo poetico. Grazie alla presenza di un testo verbale, la musica vocale può infatti essere affrontata agevolmente anche in gruppi classe con prerequisiti musicali carenti, poiché ben si presta ad illustrare procedimenti formali di base e a indurre abilità d’ascolto che risulteranno successivamente utili anche per la comprensione della musica strumentale. Purtuttavia, a seconda degli obiettivi didattici prefissi, l’atteggiamento che il docente deve assumere di fronte al testo verbale deve differenziarsi a seconda delle qualità del testo stesso, della sua estensione, del modo in cui il compositore lo ha trattato, del genere musicale. Una prima basilare distinzione avviene tra i casi di componimenti poetici autonomi che sono stati successivamente rivestiti di musica (“poesia in musica”), per i quali il testo è infatti un’opera d’arte in sé compiuta, e come tale va affrontato in classe; e i casi di testi concepiti appositamente per essere musicati (“poesia per musica”), in cui il testo è invece un prodotto artistico finalizzato a un’opera d’arte che risulterà compiuta solo se rivestita di musica. Sulla base di simili considerazioni e a partire da alcuni esempi ritenuti particolarmente significativi (due Lieder goethiani musicati da Franz Schubert, Am Flusse e Der Fischer; il madrigale del Petrarca “Datemi pace, o duri miei pensieri”musicato da Cipriano de Rore; la Messa di Notre Dame di G. de Machaut; la prima scena del “Trovatore” di Giuseppe Verdi), questo contributo illustra alcune delle problematiche che possono presentarsi al docente che voglia proporre in classe attività di didattica dell’ascolto a partire da brani musicali dotati di un testo poetico.

description: Despite progress in the metal-catalyzed synthesis of aromatic heterocycles, annulation routes towards 6-membered heterocycles remain underdeveloped. Specifically, routes towards pyridines are rare in spite of the prevalence of this moiety in novel drug candidates. Our initial efforts towards pyridines featured oximes as competent nucleophiles in the intramolecular, 6-exo dig annulation of alkynes using Brønsted acid catalysis. Two of the oxidation states required for subsequent aromatization are contained within the oxime via loss of water. An extension of this chemistry is presented and discussed, and involves the intramolecular metal-catalyzed 6-endo dig annulation of analagous alkynyl-oximes. Additionally, the discovery of a 5-exo dig annulation of related systems is discussed.

description: Laser Measurement Systems (LMS) are used in autonomous agricultural vehicles for guidance and obstacle detection purposes. In the particular case of agricultural vehicles, the efficiency of LMS measurements is affected by mechanical vibrations induced by the operation of these machines on uneven terrains. The objective of this study was to evaluate the effectiveness of a mounting system capable of reducing the transmission of mechanical vibrations to an LMS sensor installed on an agricultural tractor for the purpose of improving the detection accuracy of obstacles during field operation. A stabilization system (SS) was designed for a SICK LMS 291-S14 scanner. The LMS sensor and the SS were installed on an agricultural tractor to scan four objects positioned at known locations in the field. An experimental analysis was carried out to evaluate the detection accuracy of the LMS sensor under different operating conditions: with and without SS; with and without support bars (S); and for different types of terrains (in terms of roughness) and field operating speed. The detection accuracy of the LMS sensor was assessed by determining the difference between the known location of the four objects and their corresponding estimated location from the LMS measurements. The increase of tractor speed had a negative effect on the accuracy of the LMS sensor with an increase in the positioning error of up to 75%. However, it was not possible to establish a clear relationship between terrain roughness and the accuracy of the LMS sensor. The addition of the S systems positively affected the accuracy of the LMS sensor and resulted in a 41% decrease of the average positioning error from 0.340 to 0.201 m. Finally, the used of the SS mounting system decreased the average positioning error by 57% from 0.382 to 0.161 m. These experimental results confirmed the effectiveness of the joint use of the SS and S mounting systems in improving the accuracy of the LMS sensor mounted on an agricultural tractor through a reduction in transmitted vibrations.

description: Goals (SDGs) are going to be passed by the United Nations General Assembly. The SDGs are going to be a set ofglobally agreed goals and targets that provide orientation for future development policies. Currently soil aspects areworded in the proposal on the SDGs - even though the wording is overall a minor and partly inconsistent one. TheSDGs will be politically yet not legally binding. Enforcing and broadening the United Nations Convention to CombatDesertification could be an option for a global and legally binding instrument on soil protection. Soils are a crosscutting issue with relevance for environmental, social and economical concerns, equally. Therefore, protecting themis fundamental for sustainable development.In: Ehlers, Knut Ginzky, Harald: The Sustainable Development Goals - an important milestone on the global soil policy agenda in 2015 / Knut Ehlers ; Harald Ginzky.

Relations entre les diverses concrétions cavernicoles dans la région de l'Outaouais québécois et de la Haute Gatineau.

description: Seventy-two samples of cavernous concretions collected in 10 caves from the South-West of Quebec, were analyzed in order to (1) establish if there was spatiotemporal bonds between moonmilk, popcorn and rimstones, and (2) determine if moonmilk is a speleothem or simply a state of calcite. The results of our analyses clearly show the presence of transition zones, which translate in a space-time continuum between the sedimentary characteristics of the divers ccncretions. The presence of layers showing moonmilk particularities in popcorn and rimstone samples, and the morphological similitude between moonmilk deposits and common speleothems, suggest that moonmilk is not a speleothem by itself, but an occasional component of speleothems.

description: "Continuous thermodynamics" is a technique for modelling mixtures with large numbers of components which uses a probability density function rather than discrete components to represent the mixture composition. It has proved to be a practical and useful technique for modelling mixtures with dozens or even hundreds of components. An unresolved issue in the use of these models so far has been the role of mixing in the liquid phase, all the previous work having assumed a well-mixed droplet. With two- or three-component mixtures it is known that there are significant differences between the two extremes of well-mixed and diffusion limited droplets, the latter referring to mixing which occurs by molecular diffusion only. This paper presents a numerical solution for diffusion within a droplet of multi-component mixture modelled using continuous thermodynamics. Transport equations for the mean and variance of the fuel composition distribution function in the droplet are derived. The molecular diffusivity of the liquid mixture is calculated using a continuous thermodynamics extension of the well-known Wilke-Chang diffusivity correlation. The effects of enhanced mixing caused by internal circulation are modelled by increasing the effective diffusivity of the liquid. Vapour and liquid phase solutions are coupled at the liquid surface by matching the fluxes of the distribution moments. The results are compared to other models, including a continuous mixture version of the quasi-steady liquid phase model of Law and Law (1981). Conclusions for practical spray modelling are drawn.

description: Applicants use faking in selection interviews to create a favorable impression and to increase their chances for a job offer. Theoretical models assume that such a behavior is influenced by situational and dispositional variables. However, previous research has mainly focused on dispositional variables whereas research about situational variables is sparse. To address this gap, we conducted three studies in which we examined how competition for a job and warning interviewees that information from their answers will be verified can influence faking intentions. Furthermore, we wanted to know whether these situational variables are able to explain additional variance in faking intentions beyond dispositional variables and whether there are interactions between situational and dispositional variables. In Study 1, we only found that high competition led to slightly higher faking intentions than low competition in a student sample. In Study 2, only a warning about the verification of applicants’ answers led to slightly lower faking intentions compared to no warning concerning verification in a working sample. Furthermore, faking intentions were lower in Study 2 than in the student sample in Study 1. In Study 3, we found no impact of our situational variables in a combined sample of students and non-students. We only found slightly higher honest impression management intentions in the high competition and the verification warning condition. We also found hardly any support for interaction effects between the situational and dispositional variables. Furthermore, the situational variables did not explain additional variance beyond the dispositional variables in any of the three studies. Possible reasons for the non-significant or small effect sizes for the situational variables can be found in a qualitative analysis of answers to an open-ended question in Study 3. However, we found that Honesty-humility und all facets of the Dark Triad were related to faking intentions. These results indicate that dispositional variables in particular have an impact on faking intentions.
Peroxidation of phospholipid unilamellar vesicles containing vitamin E: A comparison with low-density lipoprotein.

description: Oxidative degeneration of human low-density lipoprotein (LDL) is implicated in the initiation of atherosclerosis, a degeneration of the arterial wall that very commonly leads to heart attack or stroke. The high incidence of this disease in developed societies has aroused an increasing interest in antioxidants with particular attention on alpha-tocopherol (alpha-TocH), the most powerful naturally occurring antioxidant. The potential of liposomes as a suitable synthetic model of LDL with standard and modifiable composition, no risk of infection and high availability was investigated. It was found that unilamellar vesicles with similar composition and diameter as LDL behave as a homogeneous system where alpha-tocopherol behaves as an antioxidant. The cause of this unexpected kinetics may lay in the lack of a lipid core in liposomes. Rather than being hidden within an LDL particle, the alpha-Toc• is forced to reside on the surface of the vesicles where it can be immediately trapped and prevented from performing the much slower chain-carrying reaction.
