▼ Radical innovation is a critical source for creating competitive advantage and value for potential customers. However, radical innovation has inherent characteristics that make a radical innovation project difficult to manage, such as: increased generativity – the aspect that describes how radical innovation outcomes are creative and novel, different than other radical innovation outcomes, and fundamental non-probabilistic uncertainty – uncertainty inherent to radical innovation cannot be mitigated using data-driven forecasting techniques. The increased generativity and fundamental non-probabilistic uncertainty characteristics of radical innovation presents challenges especially when a decision regarding the internal adoption for further development of a radical innovation concept needs to be made, as financial tools, such as Return On Investment (ROI) and Net Present Value (NPV) are widely used to evaluate and make a decision regarding the internal adoption of radical innovation concepts. The aim of this master thesis is taking a strategic design approach to design a tool, that facilitates the decision-making process behind the internal adoption of radical innovation concepts, while addressing the knowledge gap between the challenges of radical innovation, and the decision-making tools and evaluation criteria currently used. Literature review and field research, consisting of qualitative interviews with experts from academia and experts working in industry, was conducted to understand the context of the decision-making process behind the internal adoption of radical innovation concepts. The research phase revealed the knowledge gap mentioned above and insights that were used towards devising design criteria for developing a tool. Insights gathered from the literature review and field research led to the development of the
Viability Decision Canvas, a tool that facilitates the decision-making process behind the internal adoption of radical innovation concepts. The
Viability Decision Canvas is based on the
Viability Model which describes
viability as the main decision criteria when a radical innovation concept is evaluated by a company, where
viability is modeled by desirability, feasibility and suitability.
Viability Decision Canvas facilitates the evaluation and the decision-making process behind the internal adoption of radical innovation concepts by employing abductive reasoning in a Fast-and-Frugal decision tree format, that addresses the non-probabilistic uncertainty inherent to radical innovation. The
Viability Decision Canvas, besides the decision-maker, involves other relevant people (e.g. designer, engineer, marketer, senior manager, etc.) in the decision-making process to ensure organizational alignment. Being simple and structured, the
Viability Decision Canvas allows and encourages rapid adjustment to suit the specific context of the company and the context created by the radical innovation concept generativity aspect. Critical assumptions identified during the design of the
Viability Decision Canvas were…

▼ Organizational adoption of information technology is an important decision for modern enterprises. Proper use of technology can increase benefits and competitive advantage. Inappropriate use could cause failure. Most previous literature focuses on treating technology adoption as a rational decision based on the functional needs of an organization. In many cases, however, technology adoption is not due to functional needs but environmental or peer pressure (called symbolic or ceremonial adoption). Different motivations for adoption may lead to different outcome. In addition, there is no generally accepted organizational adoption
model that can include all key factors into consideration. Therefore, this study tries to understand what factors will affect an organizationâs adoption of a new information technology or use an information technology and whether different purposes (intangible value vs. tangible value) will affect the adoption or usage of information technology in organizations.
The framework of this study was extended from the Fit-
Viability Model to include the internal organizational factors and external environmental factors. We conducted a survey study and use PLS to analyze the collected data. The results show that the extended FV
model can interpret organizational IT adoption and IT usage. The purpose of adoption did have effect on the intention to adopt information technology. In the symbolic adoption situation, TEF and
viability had significant impacts on organizational intention to adopt; and in the functional adoption situation, TTF and
viability had significant impacts on organizational intention to adopt. Different purposes of adoption have less significant effect on the actual use and performance of information system. TTF and actual use had significant impacts on organizational performance, and
viability also had significant impacts on actual use of information technology in both situations. In other words, organizations can also benefit from IT adoption even if the original motivation was symbolic.

▼ In a competitive environment, Information Technology (IT) is necessary for companies to boost performance. Adoption of proper IT is very important because inappropriate use of IT can lead to the failure of organizations. In the past, many researchers have investigated the issue of business adoption of information technology from their functional needs. In many cases, however, technology adoption is not due to functional needs, but due to environmental pressures or other reasons, such as peer pressure, normative pressure and surrounding changes. Different purposes for adoption may lead to different outcomes. Hence, the purpose of this research is to investigate what factors affect an organizationâs adoption of information technology, and how different purposes (symbolic value vs. function value) can affect organizational adoption.
The framework of this paper is based on the Fit-
Viability Model to study both internal organizational factors and external environmental factors. A questionnaire survey of Taiwanese firms was conducted and PLS was used to analyze the collected data. Results show that the
model used in the paper can interpret organizational IT adoption and IT usage. We find that different factors come into play between symbolic and functional adoption. Environmental pressures have greater effects on symbolic adoption which often lead to less usage and less enhancement to organizational performance.

▼ Disorders affecting articular cartilage are amongst the most common problems in orthopaedics. Osteoarthritis, the end stage of the disease of articular cartilage, reduces the quality of life for tens of millions of people in the world, and has a profound impact on the economics of industrialized countries. Despite progress in articular cartilage research, the problem is still far from being defeated. Various models e.g. in vitro cartilage explants and in vivo animal models, have been established for cartilage research, but each has its own limitations. Thus, a novel ex vivo isolated joint organ culture model was developed. Bovine metatarsophalangeal joints were chosen as a suitable synovial joint because it consists of a hinge-type joint that is similar to the human knee joint, and has a large cartilage surface that provides enough space for multiple sampling in the same joint. The joints were isolated aseptically and placed into culture media. The viability of chondrocytes, glycosaminoglycan (GAG) content of cartilage matrix, cartilage morphology and water content of matrix were evaluated under different culture conditions, i.e. static, static with flowing media, and dynamic with different durations of the movement period. The model was used to investigate the effect on the sharp scalpel cartilage injury of adding serum to the culture medium by culturing the whole joint explants in serum-supplied or serum-free media. The feasibility of investigating the early phases of chondrocyte implantation in this model was also studied: circular holes of 2.5 mm diameter were created by making a pilot hole with a 2.0 mm drill followed by using a fresh 2.5 mm biopsy punch. Allogeneic isolated chondrocytes at different passages were aggregated as cell pellets and implanted in the holes to evaluate their integration ability and the response from the recipient cartilage. Results from the static model showed that, after 28 days culture, the chondrocytes were still alive with 66.5%, 80.9% and 46.9% viability in the superficial, middle and deep zones, respectively. The GAG content of the static model decreased 19.2% after the first week of culture and then lost another 15.0% during the third week. Paradoxically, at end of the 4th week the GAG level rebounded to some extent and increased 19.0% relative to the previous week. Interestingly, the cell viability of all three zones improved if the culture fluid was flowing as seen with the experiments carried out with stirred media or dynamic movement of the articular surfaces. (e.g. for the stirred media after 28 days of culture the chondrocyte viability was 80.6%, 92.4% and 70.4% for the superficial, middle and deep zones respectively.) The GAG content was maintained at a constant level in the contact area of the dynamic model, but decreased as in the media-stirred model and non-contact area of the dynamic model to a similar extent to that observed with the static model. In the injury model, the GAG content fell approximately 10.8% straight after the scalpel cut, but no further loss was…

▼ The suitability of an animal’s local environment is expected to influence patterns of movement and population growth rate (lambda). Landscape suitability can accordingly be estimated, based on the relative frequency and spatial distribution of good versus poor areas. This framework can be used to evaluate the landscape suitability of 14 woodland caribou (Rangifer tarandus caribou) ranges in Ontario and relate it to projected inter-range differences in movement and lambda; calculated using individual-based movement trajectories. The caribou movement simulation
model predicted that average rates of caribou displacement should decrease with increasing forage variability and decreasing variability in moose abundance. The caribou population
viability analysis
model predicted that caribou population growth should decrease with increasing density of both wolves and moose, the wolves’ primary prey. These
model predictions suggest that caribou movement and lambda could respond differently to spatial variation in food availability and predation risk.

▼ Since 1996 ABET has mandated that undergraduate engineering degree granting institutions focus on learning outcomes such as professional skills (i.e. solving unstructured problems and working in teams). As a result, engineering curricula were restructured to include team based learning—including team charters. Team charters were diffused into engineering education as one of many instructional activities to meet the ABET accreditation mandates. However, the implementation and execution of team charters into engineering team based classes has been inconsistent and accepted without empirical evidence of the consequences.
The purpose of the current study was to investigate team effectiveness, operationalized as team
viability, as an outcome of team charter implementation in an undergraduate engineering team based design course. Two research questions were the focus of the study: a) What is the relationship between team charter quality and
viability in engineering student teams, and b) What is the relationship among team charter quality, teamwork mental
model similarity, and
viability in engineering student teams?
Thirty-eight intact teams, 23 treatment and 15 comparison, participated in the investigation. Treatment teams attended a team charter lecture, and completed a team charter homework assignment. Each team charter was assessed and assigned a quality score. Comparison teams did not join the lecture, and were not asked to create a team charter. All teams completed each data collection phase: a) similarity rating pretest; b) similarity posttest; and c) team
viability survey.
Findings indicate that team
viability was higher in teams that attended the lecture and completed the charter assignment. Teams with higher quality team charter scores reported higher levels of team
viability than teams with lower quality charter scores. Lastly, no evidence was found to support teamwork mental
model similarity as a partial mediator of the team charter quality on team
viability relationship.
Foci for future research opportunities include using: a) online data collection methods to improve participant adherence to similarity rating instructions; b) story or narratives during pre- and posttest similarity rating data collection to create common levels of contextual perception; and c) support to ensure charters are integrated into the full project life cycle, not just a pre-project one time isolated activity.
Twenty five sections, on average, of EDSGN 100 are taught each spring and fall semester. Consistent instructor expectations are set for the technical aspects of the course. However, ideas to foster team effectiveness are often left to the discretion of the individual instructor. Implementing empirically tested team effectiveness instructional activities would bring consistency to EDGSN 100 curriculum. Other instructional activities that would be of benefit to engineering educators include qualitative inquiry—asking intrateam process questions (at the mid-point of the project) and in-class reflection—dedicated time, post…

▼ The Lassics lupine (Lupinus constancei T.W. Nelson & J.P. Nelson) is a rare herb of limited distribution, with fewer than 400 reproductive individuals restricted to a single square kilometer in the Lassics Geological and Botanical Area of the Six Rivers National Forest, California, USA. In addition to the vulnerability resulting from its extremely small population size, the Lassics lupine faces heavy seed predation by small mammals and encroachment of surrounding plant communities into its preferred habitat. As a stop-gap measure to prevent population decline, managers began covering a large number of the reproductive plants with herbivory exclosures in 2003, but the population-level effects of seed predation and the effectiveness of this caging treatment were unknown. In this study, I used ten years of demographic monitoring data collected by the US Forest Service to build a stage-structured matrix
model, project population growth, and estimate the probability of species extinction in the next 50 years. The
model included vital rate estimates for each of three main sites, as well as vital rate correlations between and within sites and years. I used a one-way life table response experiment (LTRE) to quantify the effects of caging on the population growth rate. Finally, I used a regression LTRE to estimate the proportion of the population at each site that must be caged to avoid population decline. I found that in the absence of seed predation, the Lassics lupine population growth rate would be quite robust (??s = 1.17), but without continued human intervention (i.e., caging), the current rate of seed predation is projected to drive the population to extinction (??s = 0.92). Remarkably, the LTREs revealed that in order to best forestall population decline, plants should be caged at roughly the same proportions as they are under current management practices. Early identification by managers of the role of seed predation in Lassics lupine population decline was likely instrumental in the prevention of a substantial reduction in population size. The success of the current efforts can only be considered a deferment, however, and without further research into the underlying causes of this untenable seed predation rate, the Lassics lupine could be unable to recover.

▼ The invasive emerald ash borer beetle (Agrilus
planipennis, EAB) has caused significant ash tree (Fraxinus spp.)
declines and forest changes, which include loss of canopy cover and
increased numbers of invasive plant species (Hausman et al. 2010).
My focus was to assess ash population dynamics and environmental
factors that could play a role in ash survival. My research used a
population
viability analysis (PVA) approach that combined
literature review, targeted field studies, and greenhouse
experiments to examine green ash trees (F. pennsylvanica) in the
post-EAB peak infestation (aftermath) forest. Aftermath forests
dynamics between ash and EAB are likely different from the initial
infestation. I developed historic and worst case stochastic stage
based ash population models as part of a PVA; these scenarios
reflect time periods before and after EAB invaded Northwest Ohio.
The ash population growth rates were estimated as 0.76 and 1.03,
respectively, in worst case versus historic scenarios. Results
indicated that population changes were more sensitive to survival
and growth of the smallest stage class in the worst case scenario,
where ash populations became locally extinct within 41 years. I
examined ash parameters with little known information, such as
germination, seedling survival and their environmental conditions,
and mature ash tree neighbors. My germination experiments from the
lab and the field resulted in a very low germination rate from the
local population. Seedling survival was high and they were affected
by leaf litter, bare ground and dead coarse woody debris. The
number of ash neighbors within 6 m was significantly lower for the
healthiest ash canopy class compared to declining health classes (p
= 0.02). I modeled changes that could occur to the green ash
aftermath forest (2010-2017) by introducing EAB periodically as a
catastrophe that lowered ash survival and simulated a slow ash
survival recovery. Management scenarios included, 1) reduced EAB
catastrophes, 2) increase ash survival and growth, 3) individual
ash size classes survival increased, and 4) planted EAB-resistant
ash trees. Reduced EAB catastrophes, protecting the largest and
smallest ash size class, and increase survival and growth provided
an improvement for the population. Planting EAB-resistant trees
allowed for a partial recovery, where saplings performed better
than seedlings. While conservative, these green ash models
indicated that increased tree survival improved population
recovery, and EAB population fluxes have a large influence on ash
population persistence. PVA, as this research demonstrates, allows
us to quickly identify factors that influence the population
viability of threatened species, allowing for the development of
strategies that promote recovery.

▼ O objetivo deste trabalho é introduzir um método para a avaliação da viabilidade das exportações focando no crescimento econômico em termos de PIB do resto do mundo. Para isso são utilizados modelos locacionais e modelos de regressão baseados em modelos gravitacionais de comércio, ambos em conjunto. Este trabalho também apresenta de forma matemática e microeconômica a relação existente entre ambos os modelos. O estudo também testa o método introduzido por meio de um exemplo utilizando as exportações do complexo soja brasileiro entre 1996 e 2010. Os resultados obtidos não descartam o uso da metodologia proposta como instrumento de análise da viabilidade das exportações.
The aim of this work is to introduce a method for assessing the viability of exports focusing on economic growth of the rest of the world in terms of GDP. For this purpose, location models and regression models based on gravity models of trade are used together. This research also presents a mathematical explanation and the microeconomic relationship between both models. Also this work uses the example of Brazilian soybean complex exports between 1996 and 2010 to test the introduced method. The results do not rule out the use of the proposed methodology as a tool for analyzing the viability of exports.

▼ L'étendue des mouvements que les robots humanoïdes peuvent réaliser est fortement limitée par des contraintes dynamiques. Une loi de commande qui ne prend pas en compte ses res- trictions, d'une manière ou autre, ne va pas réussir d'éviter une chute. La Commande Prédictive est capable de considérer les contraintes sur l'état et le contrôle de manière explicite, ce qui la rend particulièrement appropriée pour le contrôle des mouvements des robots marcheurs.Nous commençons par dévoiler la structure spécifique de ces contraintes, démontrant notamment l'importance des appuis au sol. Nous développons ensuite une condition suffisante pour l'évitement d'une chute et nous proposons une loi de commande prédictive qui y réponde. Cette formulation nous sert ensuite pour la conception des contrôleurs pratiques, capables d'un contrôle plus efficace et plus robuste des robots marcheurs humanoïdes.
The range of motions that humanoid robots are able to realize is strongly limited by inherent dynamical constraints so that any control law that does not consider these limitations, in one way or another, will fail to avoid falling. The Model Predictive Control (MPC) technique is capable of handling constraints on the state and the control explicitly, which makes it highly apt for the control of walking robots.We begin by unveiling the specific structure of these constraints, stressing especially the impor- tance of the supports on the ground. We give thereupon a sufficient condition for keeping balance and formulate an MPC law that complies with it. This formulation serves us then for the design of practicable controllers capable of more efficient and more robust control of humanoid robots.

▼ L’une des principales problématiques du développement de produits biologiques, comme les probiotiques, réside dans l’impact du processus de fabrication sur la souche d’intérêt. Le maintien de l’activité thérapeutique est d’un intérêt capital pour obtenir l’effet bénéfique et, des travaux ont également optimisé les propriétés de la souche Lcr35® au travers du procédé de fabrication. Ainsi, toutes les étapes de fabrication du produit sont autant d’étapes qui peuvent modifier les caractéristiques de la souche bactérienne. La compression a été reconnue comme étant une étape qui permet d’éliminer les contaminations bactériennes et a également été décrite comme néfaste pour la viabilité d’une souche probiotique. Ces données constituent donc un a priori négatif au développement de probiotiques comprimés.Inversement, cette forme galénique est reconnue pour améliorer la demi-Vie des produits et améliorer la stabilité des bactéries dans un milieu gastrique. Cependant, aucune étude complète des propriétés d’une souche probiotique, après compression, n’a été effectuée. Or, afin d’établir un dossier d’AMM, toutes ces propriétés se doivent d’être vérifiées sur le produit final.Les travaux présentés se sont donc attachés à étudier les principales propriétés de la souche Lcr35® après compression. Tout d’abord, la perte de viabilité initiale en fonction de la pression de compression a été évaluée expérimentalement et une loi de décroissance d’ordre 1 est proposée. Un tel modèle permet ainsi d’anticiper la perte de viabilité selon la formulation et les conditions de compression. D’autre part, le profil génétique ainsi que le profil d’expression des gènes de la souche Lcr35® ont été étudiés après compression. Ni l’un ni l’autre n’a été modifié par le stress mécanique généré par la compression. De même, les propriétés d’inhibition du pathogène vaginal C. albicans ainsi que la résistance à pH acide de la souche sont maintenues. La résistance au pH gastrique est même améliorée par une protection mécanique vis-À-Vis du milieu.Selon les données de stabilité (ICH Q1A), la viabilité de la souche Lcr35® n’est pas non plus affectée par la compression. Les données de stabilité ont fait l’objet d’une modélisation par l’équation d’Arrhenius permettant d’obtenir un modèle fiable de prédiction de la stabilité, à partir des données en conditions accélérées (40°C).Dans une approche QbD de développement des produits pharmaceutiques, ces données serviront de base de comparaison pour la caractérisation de formulations en développement où des éléments tels que le milieu de culture, la souche ou la forme galénique peuvent être modifiés.Cette caractérisation globale de la souche Lcr35®, après compression, a permis d’infirmer l’a priori négatif sur la compression des bactéries. Ces travaux ont permis de comprendre, de caractériser et de modéliser les aspects liés à la compression des probiotiques. Ils constituent un prérequis primordial au développement d’un nouveau produit sous la forme d’un comprimé. Suite à une étape de développement complémentaire, ils…

▼ Historical campuses enabled post-Age of Enlightenment organizations’ operations and allowed them to adapt with times, supporting their processes of adaptive reuse transformation throughout the institutions’ recursive managerial cycles. However, the radical reforms which concerned these organizations since the second half of the 20th century, disabled those mechanics and instated a diffuse phenomenon of dismissal of their historic campuses, instating processes of abandon, demolition, degradation or degeneration and entailing the steady loss of their architectural, urban, functional, economic, historic and socio-cultural values.In the perspective of re-enabling, promoting and fostering fully-sustainable adaptive reuse transformations of the heritage to avoid the value losses, this research recognizes the lack of integration between the intervention domains participating in adaptive reuse operations as the main cause of the phenomenon. Specifically, it points to the impossibility for organizations to inform, support and assess such cross-domain broad-spectrum transformations following the serial structure of current adaptive reuse operational models. Once observed the specific managerial, entrepreneurial and architectural characters of such transformations, the research focuses on the analysis of their processes and procedures in order to define the extents up to which they can be integrated and synchronized. This results in a parallelly-structured operational
model in which the coherent processes of the three intervention domains are executed synchronously throughout the identified procedural and operational phases. These phases are then consolidated by defining the conduction tools available to the process managers (and to the ones of each individual domain), the nature and the relevance of the information transfer among the processes within a same procedural phase and/or the previous/next one and finally the reciprocal contributions of each domains in respect to the others. The research then focuses on the theoretical validation of the proposed alternative operational
model for adaptive reuse transformation of defunctionalized historic campuses. A comparative analysis reveals an increased ability of adaptive reuse operations conducted through the integrated operational
model to consistently address the interests of the involved stakeholders and to be backed by major support networks. Additionally, it shows their higher aptitude in managing the risks inherently related to the operations by allowing its incremental phasing, which provides an otherwise absent degree of tolerance for ambiguity and proofs them from the excessive hindrance represented by intrinsic and extrinsic transformation factors. The integrated operational
model also prompts to more fully sustainable transformations thanks to the coexistence of the control processes pertaining to each intervention domain. Overall, the proposed
model better allows to restore, preserve and enhance the architectural, urban, functional, economic, historic and…

▼ Background and motivation: The event of neural Ca2+ overload is known to have
several deleterious effects resulting in cell death caused by ischaemia, hypoglycaemia,
hypoxia and several neurodegenerative diseases such as Alzheimer's disease,
Parkinson's disease and AIDS-related dementia. In vitro models for the investigation
of the mechanisms involved in Ca2+ overload include brain slice preparations,
neuronal cultures as well as acutely isolated neurons, mostly from the hippocampus
and cortical brain areas. Additional models for investigating Ca2+ overload may bring
about new knowledge to areas of the phenomenon that are still unresolved.
Methodology: In this study, several theoretical Ca2+ overload-related interventions
were combined aimed at inducing cell death in acutely isolated rat dorsal root ganglia.
To elucidate the mechanism/s involved in the cell death observed following exposure
to this intervention, the effects of several alterations to the intervention's composition
were assessed. This examination was extended by the addition of several recognized
and potential protective compounds to the intervention. Cell death was indicated by
the trypan blue exclusion assay and recorded after 18 hours exposure to the
interventions by counting live and dead neurons under a light microscope.
Results and conclusions: The goal was to evaluate the possible application of dorsal
root ganglia as a model for neural Ca2+ overload outside the brain. Since Ca2+w as
required for cell death to be induced, it is concluded that the observed cell death was
indeed primarily due to Ca2+ overload. Besides extracellular Ca2+, KC1-induced
depolarization was also required for cell death to be induced, while the antagonists did
not demonstrate significant protection against cell death. Based on the results, the
mechanism of Ca2+ overload could not be defined beyond doubt, but the voltage activated
Ca2+ channels are likely to be involved.

▼ For open-pollinated species, the success of a pollen grain pollinating a receptive plant is a function of when it is shed, its dispersion in the atmosphere, and the chance of germination upon deposition. Most studies of pollen dispersion have focused on a source and surrounding fields in relatively flat terrain, but dispersion to distances over 20 km has been reported in regions of complex terrain. For this reason, a more detailed examination of atmospheric dispersion over long distances and the components of dispersion - shed, transport, and successful pollination - was undertaken. This dissertation uses numerical models to predict these components in order to improve simulations of dispersion over long distances. Chapter One provides an overview of work previously done in pollen dispersion. Chapter Two describes a model that uses empirical relationships between pollen release and meteorological variables to predict diurnal variations in maize pollen shed. The model captured the general pattern of shed and predicted the time of peak shed on most days. In Chapter Three, a meteorological model was combined with a Lagrangian dispersion model to predict bentgrass pollen dispersion over complex terrain. The models predicted pollen deposition in locations where outcross was previously reported over 20 km from the source. However, pollen was not predicted to be deposited on upwind slopes of mountains or in valleys more than a few kilometers from the source. Chapter Four examines how thermally-generated updrafts resulting from surface sensible heat flux and mechanically-generated updrafts associated with complex topography affect dispersion. We determined the gaps in pollen dispersion found in Chapter Three resulted from additional lift created by convergence on the windward side of mountains and thermally-induced flow that traveled up valley walls and mountain slopes. Chapter Five examines how maize pollen viability is affected when pollen grains are lifted higher in the atmospheric boundary layer. Viability was predicted to be as much as 30% higher when the atmospheric conditions along a pollen grain's trajectory are used compared to estimates of viability using conditions at the Earth's surface. Chapter Six summarizes the dissertation. The results of this work are expected to improve future models of pollen dispersion, leading to more accurate predictions of outcrossing. Also, the methods described here are not limited to maize or bentgrass pollen, but can be modified for applications to other biological particles that rely on atmospheric conditions for dispersion.

Multidisciplinary Investigation Identifies Novel

▼ During metastasis, tumor cells dissociate
from the primary tumor, disseminate through the vasculature, arrest
in the capillary bed, and colonize secondary organs. Although at
all of these stages surviving tumor cells hold a potential for
colonization, mechanical arrest is particularly important since
cell entrapment is absolutely necessary for tumor outgrowth.
However, the subcellular response of circulating tumor cells (CTCs)
to the extreme shear stress exerted during transit through the
vasculature prior to and during mechanical arrest remains largely
unknown. In this work, we present an integrative platform that
combines the use of a microfluidic device and a computational
model. Together, they serve as a tunable system to reliably
reproduce the mechanical arrest of tumor cells and quantitatively
determine their physical response to precisely controlled shear
stress. The design of our platform is based on biological
observations of CTC arrest within the mouse brain microcapillary
bed, and was validated to be physiologically relevant for the
animal
model used. Using this platform, we show for the first time,
an insight into subcellular responses of CTCs at the stage of
mechanical arrest. We found that during mechanical arrest single
tumor cells experience extreme morphological deformations, an
increase in membrane stress, and increased mitochondrial fission,
all dependent on the magnitude of fluid shear stress applied. In
this work, we demonstrated for the first time that shear stress can
trigger mitochondrial fragmentation in CTCs, followed by increased
cleavage of PINK1, which together serve as a self-protective
mechanism to inhibit mitochondrial clearance. A key finding
presented in this work is the regulatory role that PTEN has on
maintaining the mitochondrial network structure and continued
mitophagy. Loss of PTEN resulted in increased mitochondrial fission
and Parkin downregulation, which together with the cleavage of
PINK1 demonstrate enhanced protection from mitophagy upon exposure
of CTCs to shear stress, suggesting it as a self-protective
mechanism to inhibit mitochondrial clearance during transit through
the vasculature and mechanical arrest. Although not fully
investigated in this work, mitochondrial fission is speculated to
be Drp1 independent. An interesting finding was the loss of
viability in PTEN deficient CTCs, which opposes the protective role
that mitochondrial fragmentation and mitophagy inhibition offer.
Our data suggests that loss of PTEN may induce an increased
fragility in plasma membrane upon exposure to shear stress, while
simultaneously activating pro-survival mitochondrial dynamics.
Together, our investigation brings out a novel mechanism where CTCs
show an adaptive response to shear stress through remodeling of
mitochondria and inhibition of mitophagy, and where loss of PTEN
plays an essential role modulating Parkin expression to sustain
cell
viability during transit through the vasculature and
mechanical arrest.

▼ Butterfly populations are in decline in Florida. An example is the Florida leafwing, Anaea troglodyta floridalis (Nymphalidae), a species endemic to the pine rocklands in South Florida. I used a variety of approaches to investigate the population dynamics of leafwing butterflies, including two widespread congeners, A. aidea and A. andria. This dissertation describes two population models, one that evaluated the extinction risk and sensitivity of A. t. floridalis to disturbances such as fire, and the other evaluated the sensitivity of annual population dynamics in response to seasonal life history. Using demographic data from field surveys and laboratory experiments, my work described the life cycle of individuals from egg to caterpillar, and through metamorphosis and adulthood as butterflies. The models I built represented the life cycle at multiple time scales, e.g., within seasons, between seasons within a year, and between years. Per capita predation and temperature were important within season factors affecting the survival and growth rates, respectively, of juveniles. Between seasons, the periodic stage-structured matrix
model I built predicted that natural selection should favor individuals with high survival in the winter, and high reproductive output during the breeding season, a prediction that explains the differences between seasonally-dependent morphological forms of adult leafwing. Important for between year variation, I demonstrated the positive effect of fire, which decreased extinction risk and is necessary to maintain the pine rockland ecosystem endemic to South Florida. For the first time, my work integrated the entire butterfly life cycle through all seasons within an annual cycle.

▼ An understanding of the links between population dynamics and environmental variability, combined with information on how these factors change over time, is necessary to understand and predict population dynamics and viability in changing environments. Scientists need also to acknowledge uncertainties in their understanding of systems, which is straightforward using Bayesian statistics. This allows us to know with more certainty, although it sounds contradictory, how a biological system works.
First, the hierarchical model developed in paper I illustrates how conclusions and decisions to be made based on population viability analysis could be dangerously misleading if uncertainties are not taken into account. The probabilistic long-term growth rate parameter, log λS, is estimated for the first time, and I discuss a new way to interpret this parameter. Based on simulations done with this model, we stress in paper II that ignoring relevant uncertainty sources generally gives an unwarranted impression of confidence in the results. The procedure used in this work increased our understanding of the relative importance of different uncertainty sources, and helps choosing which sources to include when evaluating the impact of climate change.
Second, the modelling approach developed in paper III allows us to estimate colonization rates of non-equilibrium metapopulations. It reconstructs a time series of the most likely colonization events leading to the observed pattern of occupied and non-occupied patches. It requires only snapshot data on the occurrence pattern, as well as data on patch ages and on the landscape history. In this case I stress how the choice of a modelling approach has important implications on metapopulation viability analysis.
I finally draw conclusions on the methodological advances achieved, and on the implications for the conservation of the study species. Using Bayesian statistics both process uncertainty, and parameter uncertainty and variability are captured, and predictions are turned into a probabilistic statement that is useful for management. Uncertainties are no longer an obstacle, but a mandatory aspect to include in population viability analysis.

▼ We have just survived the most violent century in history.
Ballistic skeletal injuries continue to kill or injure hundreds of thousands of people globally every year and yet our knowledge of these injuries remains incomplete. The aim of this thesis is to analyze some of the orthopedic, biomechanics and forensic aspects of ballistic skeletal injuries to better understand their clinical significance and optimal management. In doing we cover aspects of bacterial contamination and cellular survival around direct ballistic fractures. We also analyze indirect and remote ballistic femoral fractures. From a biomechanics perspective we analyze how bone breaks when impacted by a projectile and what energy transfer is involved. And from a forensic perspective we analyze the morphology of bony wounds and describe a technique for identifying a bullet from the bullet wipe.

▼ Given the current situation in which it is the global energy sector, biofuels have been gaining more space, earning special attention the ethanol, which has shown growing demands. From this scenario, the objective of this work was to develop a bioprocess technically and economically practicable for ethanol production from cashew apple juice, using yeast Saccharomyces cerevisiae (CCA008) genetically modified containing a flocculent gene (FLO5α). The work was divided in 4 four stages that are linked throughout the study. In the first stage was evaluated the temperature influence (26, 30, 34, 38 and 42ÂC), the inoculum concentration (3, 5, 8 and 10 g.L-1) and the stirring speed (80, 150, 300, 490, 650 and 800 rpm), so it could be determined the best conditions to maximize ethanol production. It was observed that the temperature operating parameter, the initial cellular concentration, substrate concentration and stirring exerted influence on the alcoholic fermentation of the cashew apple juice. The best performance to the fermentative process (98,8 %) happened when the process was conducted at 34 ÂC, under 150 rpm stirring and 5 g.L-1 of initially cell concentration. The second stage was intended to describe the process efficiency in face of the operation parameters evaluated in fermentation. To this end, it was successfully used statistic models to describe the interaction between the initial substrate concentration, temperature, initial cell concentration, stirring and their possible effects on the yield. The
model that best fit the experimental data was used to obtain the optimum conditions from the operating variables, indicating the following conditions as great: substrate concentration (S0) of 102 g.L-1, temperature (T) at 34ÂC, inoculum concentration (X0) of 5 g.L-1 and stirring (Agit) of 140 rpm, predicting a 98,80 % of efficiency. In the third stage was studied ethanol production in optimum conditions, being used to implement the scale up process, in which the data obtained in a 1L bioreactor batch were used to predict the fermentation behavior in a 14L bioreactor batch, using the volumetric power consumption as a parameter to scale-up. Using this factor as being of 10,67 kW/m3, it was possible to calculate the fermenter stirring power in a 14 times bigger volume, as well as foresee which stirring would be necessary so the fermentation can occur, similarly as in the lower volume fermenter. Results showed that yield from the 14L bioreactor were satisfactory, having a small difference (96,56 % Â 0,3 %) between yield from the 1L bioreactor (98,80 % Â 1,6 %). The fourth and last stage was rated the technical and economic
viability of the process. Analyzing results, it is possible to say the industrial process here proponed has shown technical
viability, since the value obtained for the process yield (68 L/ton), was close to sugar cane fermentation (61 â 72 L/ton). However, it did not show economic
viability since the industrial unity provides negative cash flow (- R$ 93.840.874) in the end of 10 years that…

▼ Hierarchical models constitute one of the most useful
classes of statistical models with applications in a broad range of
disciplines including, among others, social sciences, epidemiology
and environmental sciences. The widely used linear mixed effects
models, their extension to generalized linear mixed models (GLMMs),
and state-space models all arise as special cases of general
hierarchical models. These models provide a powerful framework for
modeling the effects of latent processes, called random effects,
whose variability is only manifested through the observed data.
However, maximum likelihood estimation for these models poses
significant challenges because the likelihood function involves
intractable integrals whose dimension depends on the random effects
structure. In this thesis, we use data cloning; a simple
computational method that exploits advances in Bayesian
computation, in particular the Markov Chain Monte Carlo (MCMC)
method, to obtain maximum likelihood estimators of the parameters
along with their asymptotic standard errors in general hierarchical
models. We also suggest a frequentist method to obtain prediction
intervals for random effects. Determining estimability of the
parameters in a hierarchical model is a very difficult problem in
general. This thesis also develops a simple data cloning based
graphical test to not only check if the full set of parameters is
estimable but also, and more importantly, if a specified function
of the parameters is estimable. We exemplify our methodology by
analyzing various GLMMs and state-space models. Using a focal
population time series of song sparrow (Melospiza melodia) on
Mandarte Island, British Columbia, Canada, we show that data
cloning can be efficiently employed to fit nonlinear non-Gaussian
state-space models for conducting population viability analyses in
the presence of observation error and missing values. The quality
of MCMC based Bayesian inference, and for that matter, that of data
cloning based estimates, is crucially dependent on appropriate
diagnosis of MCMC chains’ convergence. This thesis also develops a
diagnostic method for convergence of MCMC algorithms using a new
empirical characteristic function (ECF) based nonparametric test
for comparing k-multivariate distributions. We show that the ECF
based convergence diagnostic is particularly useful in cases where
the target distribution is multimodal.

▼ Ecological problems are typically multi faceted and need to be addressed from a scientific and a management perspective. There is a wealth of modelling and simulation software available, each designed to address a particular aspect of the issue of concern. Choosing the appropriate tool, making sense of the disparate outputs, and taking decisions when little or no empirical data is available, are everyday challenges facing the ecologist and environmental manager.
Bayesian Networks provide a statistical modelling framework that enables analysis and integration of information in its own right as well as integration of a variety of models addressing different aspects of a common overall problem. There has been increased interest in the use of BNs to model environmental systems and issues of concern. However, the development of more sophisticated BNs, utilising dynamic and object oriented (OO) features, is still at the frontier of ecological research. Such features are particularly appealing in an ecological context, since the underlying facts are often spatial and temporal in nature.
This thesis focuses on an integrated BN approach which facilitates OO modelling. Our research devises a new heuristic method, the Iterative Bayesian Network Development Cycle (IBNDC), for the development of BN models within a multi-field and multi-expert context. Expert elicitation is a popular method used to quantify BNs when data is sparse, but expert knowledge is abundant. The resulting BNs need to be substantiated and validated taking this uncertainty into account. Our research demonstrates the application of the IBNDC approach to support these aspects of BN modelling.
The complex nature of environmental issues makes them ideal case studies for the proposed integrated approach to modelling. Moreover, they lend themselves to a series of integrated sub-networks describing different scientific components, combining scientific and management perspectives, or pooling similar contributions developed in different locations by different research groups.
In southern Africa the two largest free-ranging cheetah (Acinonyx jubatus) populations are in Namibia and Botswana, where the majority of cheetahs are located outside protected areas. Consequently, cheetah conservation in these two countries is focussed primarily on the free-ranging populations as well as the mitigation of conflict between humans and cheetahs. In contrast, in neighbouring South Africa, the majority of cheetahs are found in fenced reserves. Nonetheless, conflict between humans and cheetahs remains an issue here. Conservation effort in South Africa is also focussed on managing the geographically isolated cheetah populations as one large meta-population. Relocation is one option among a suite of tools used to resolve human-cheetah conflict in southern Africa. Successfully relocating captured problem cheetahs, and maintaining a viable free-ranging cheetah population, are two environmental issues in cheetah conservation forming the first case study in this thesis.

▼ Die Doktorarbeit studiert unendliche Ensembles gewöhnlicher
Differentialgleichungen mit gemeinsamen Monotonieeigenschaften, wie sie in der
Nachhaltigkeitsforschung auftreten. Es werden neue Verfahren zur Behandlung
von solchen Ensembles entwickelt und zur modellgestützen analyse verschiedener
Problemen des nachhaltigen Umgangs mit natürlichen Ressourcen erprobt.
Qualitative Differentialgleichungen (QDEs) und Differentialinklusionen werden
in den neu formalisierten Rahmen der Modellensembles eingebettet. Darunter
versteht man eine Menge von Funktionen auf einem Zustandsraum, die
Anfangswertprobleme definieren. Für eine QDE schreibt man eine Matrix von
Vorzeichen vor und erhält als Modellensemble die Menge aller Funktionen, bei
denen die Einträge der Jacobimatrix dem Vorzeichen nach der vorgeschriebenen
Matrix entsprechen. Angewendet werden die neuen Methoden auf die Armuts-
Degradations-Spirale in Entwicklungsländern, Fischereimanagement (insbesondere
industrialisierte Hochseefischerei und partizipatorische Managementansätze),
sowie Wassermanagement zur Vermeidung von Eutrophierung. Derartige Anwendung
stellen besondere anforderungen an die Modellierung, insbesondere
Unsicherheiten im Wissen und der Bedarf nach verallgemeinerbaren Resultaten.
Es wird gezeigt, dass Modellensembles hierfür geeignet sind. Basierend auf der
neu eingeführten graphentheoretischen Formulierung von QDEs werden vier
innovative Verfahren zum Umgang mit großen QDEs entwickelt. Hierbei wird die
Viabilitätstheorie begrifflich wie methodisch für Abstraktions- und
Restriktionsverfahren eingesetzt. (i) Die graphentheoretische Fassung viabler
Mengen führt zur No-return Abstraktion, die einen engen Bezug zu starken
Zusammenhangskomponenten aufweist. Damit lassen sich Zustandsgraphen
aggregiert darstellen und bezüglich Nachhaltigkeitsfragen evaluieren. (ii) Die
Restriktion der zulässigen Lösungen erlaubt es, Kanten von untergeordneter
Bedeutung aus dem Zustandsgraphen zu eliminieren. (iii) Die Restriktion auf
Systeme, bei denen die Einträge der Jacobimatrix eine vorgegebene partielle
Ordnung aufweisen, ermöglicht die Elimination weiterer Pfade. (iv) Zuletzt
werden Intervallschranken für die Einträge der Jacobimatrix berücksichtigt.
Die Anwendungen zeigen, dass mit diesen Methoden neue und robuste
Eigenschaften auch sehr allgemeiner Modelle zum Management natürlicher
Ressourcen gewonnen werden können. Ihre Stärken für den Entwurf alternativen
Politikoptionen werden deutlich.

▼ To better understand the impact of task conflict in work teams, an incremental, multi-level model is developed, which distinguishes individual-level perceptions of conflict from more overt group-level manifestations of conflict. Task conflict is conceptualized as being detrimental for teams only to the extent that it positively predicts relationship conflict. The positive relationship between task conflict and relationship conflict is referred to as conflict spillover. The composition of team members’ underlying beliefs concerning the functional value of task conflict (referred to as conflict values) is examined as a moderator of conflict spillover. It is proposed that perceptual conflict spillover is smaller among team members who hold positive conflict values, and that manifest conflict spillover is smaller among teams composed primarily of members who hold positive conflict values. Hypotheses were tested in a longitudinal study of 59 student teams (294 individuals). At the team level, the diversity of team members’ conflict values was found to moderate manifest conflict spillover, such that the association between task and relationship conflict was significantly positive for teams composed of members who held more diverse conflict values. For teams composed of members who had less diverse conflict values, there was no significant association between manifest task conflict and manifest relationship conflict. As a result of these significant differences in conflict spillover, manifest task conflict indirectly and negatively predicted the task performance and viability of teams containing more diverse conflict values, but did not significantly impact the effectiveness of teams with less diverse conflict values. At the individual level, the significant positive association between perceived task conflict and perceived relationship conflict was not moderated by individual conflict values. However, because of this perceptual conflict spillover, task conflict perceptions also indirectly and negatively predicted team members’ personal willingness to continue working in the team. Results of this dissertation highlight important differences in the ways that conflict operates at the individual and group levels. Having identified the diversity of conflict values as a moderator of manifest conflict spillover, this dissertation outlines areas for further academic and practical knowledge development concerning the prevention of dysfunctional team dynamics.

▼ Eastern Sand Darter (Ammocrypta pellucida) is listed as Threatened under the Canadian Species at Risk Act. Canadian populations are declining primarily due to the siltation of sandy depositional areas, the preferred habitat of the species. Little other relevant biological information is available for most Canadian populations and only limited information is available for populations in the United States. To supplement the paucity of information, this study collected biological information on A. pellucida during field surveys in 2006- 2007 from 10 sites located around the Big Bend Conservation Area in the lower Thames River, Ontario, Canada. Collected data were used to estimate critical life history traits including: longevity, fecundity, clutch size and number, growth, survival, age-at-first-maturity and cohort age structure. Longevity was 3+ years, with age-at-first-maturity being 1+ for both sexes. A minimum of 2 clutches, were laid per year with an average clutch size of 71 eggs. Average density within in the study area was 0.36 ± 0.11 A. pellucida/m². Quantitative comparison of lower Thames River biological information with a more southerly A. pellucida population in the Little Muskingum River, Ohio, demonstrated little latitudinal variation between the populations. Data comparison suggests that localized environmental factors are affecting biological characteristics, in particular water temperature that may be controlled by differences in riparian cover and/or groundwater input. Field derived life history information was used to create a Leslie matrix model which was used for population viability analysis. Perturbation analyses of reproductive scenarios involving changes in clutch numbers and size and age-at-first maturity found large variations in the finite rate of population growth. Elasticity analyses further indicated that 0+ survival and 1+ fertility were the limiting life history parameters. Thus allowing fish to survive until first reproduction would have the largest overall impact on improving population viability. Inclusion of environmental stochasticity in the model facilitated estimation of extinction probabilities in the range of 0.13 to 0.21 within 100 years. Based on the above, it is recommended that management activities for protection and restoration of A. pellucida focus on habitat protection of nursery and spawning areas.

▼ The key aims of this work were to 1) develop a numerical model that would be capable of predicting fluidised-bed dryer operating parameters (including bed temperature, air humidity, and solids moisture content), 2) find the key parameters affecting the viability of yeast, and 3) predict the viability of yeast throughout the drying process. The numerical model developed uses the reaction engineering approach to estimate the drying kinetics and has a strong physical basis with the only fitted parameters being those used for the GAB isotherm. Agreement between model predictions and experimental data was excellent, the maximum root-mean-square errors were 3.1 °C, 1.8 g of water per kg of dry air, and 2.3% in the bed temperature, air humidity and the final moisture content on a wet-basis, respectively. In the second portion of this study, the effect of drying conditions on the viability of yeast cells was studied to gain an improved understanding of the mechanisms affecting yeast viability during fluidised-bed drying. The results of this research showed the major viability losses (dead cells) only occurred when the moisture content on a wet-basis was below 15%. It was also found lower bed temperatures (30-40 °C) resulted in fewer compromised cells than higher bed temperatures (above 40 °C) for moisture contents below 15%. In the final chapter, a response surface model has been fitted using IBM SPSS® (V.24) to predict the viability as a function of both temperature and moisture content, wet-basis. The response surface model was combined with the numerical model to give predictions of the viability as a function of the operating conditions. The model predictions and experimental observations showed good agreement, with the root-mean-square error in the viability predictions being less than 3%.

▼ Sous contraintes industrielles, les micro-organismes sont soumis à différents stress technologiques, liés à leur culture en réacteur de grande taille, altérant leur viabilité et les performances des procédés. Les fluctuations des paramètres physico-chimiques (température, pH, …) sont responsables de cette baisse d’efficacité de la fermentation. Afin de contribuer à l’intensification des performances des procédés de production de bio-éthanol, ce projet de thèse propose d’améliorer la robustesse d’une souche industrielle de Saccharomyces cerevisiae productrice d’alcool vis-à-vis d’un stress environnemental : la température. La stratégie générale de ce projet réside dans l’obtention d’un mutant plus tolérant que la souche sauvage au stress appliqué par abaissement de son taux de décès. Un pilote original de culture en continu a été mis en place, couplant mutagénèse aux UV, générant des modifications génétiques et pression de sélection par des variations de température, permettant la sélection des variants les plus robustes. Un modèle phénoménologique a été développé afin de simuler les cinétiques microbiennes selon le mode de conduite du pilote et d’optimiser les conditions de fonctionnement nécessaires à l’obtention des futurs variants. Ce modèle cinétique fait intervenir l’influence de la température sur les cinétiques de croissance, de décès cellulaire et de production d’éthanol chez Saccharomyces cerevisiae. Ces cinétiques ont été quantifiées expérimentalement en fonction de la température et des traitements de mutagénèse par UV. Grâce aux conditions obtenues par simulation, des cultures en mode continu ont été réalisées et des variants obtenus ont été caractérisés, en condition de production intensive d’éthanol, sur la base de leurs performances en termes de croissance, de décès et de capacités fermentaires. Cette stratégie a permis de sélectionner un variant possédant une meilleure robustesse vis-à-vis de la température, caractérisé par un taux de décès plus faible que celui de la souche sauvage. Néanmoins ce variant ne se caractérise pas par de meilleures performances fermentaires
Under industrial constraints, microorganisms are exposed to various stresses, due to their cultivation in large scale bioreactor, altering their viability and the performances of bioprocesses. Fluctuations in physico-chemical parameters (temperature, pH, ...) are responsible for this reduction in fermentation efficiency. This Ph.D project intends to improve the robustness of an industrial ethanol producer Saccharomyces cerevisiae strain under heat stress, in order to improve its industrial production of bio-ethanol under temperature fluctuating environment. The strategy of this project is to obtain a mutant more tolerant than the wild type strain to heat stress, possessing a lower death rate. An original continuous culture reactor has been designed, coupling UV mutagenesis (generating genetic modifications) and selection pressure (temperature) to select the most robust variant. A phenomenological model was proposed to simulate…

▼ Globally, millions of leprosy patients suffer irreversible peripheral nerve damage resulting in blindness or other disabilities as a consequence of Mycobacterium leprae infection. Schwann cells, the neural target of M. leprae, have a central role in leprosy histopathology including axonotrophy, altered myelin architecture and demyelination. The mechanisms of nerve damage have not been fully elucidated but appear to be the direct result of M. leprae within Schwann cells or a combined effect with an aggressive immune response to M. leprae within the nerves. There is no standardized in vitro model for the study of M. leprae interactions with the Schwann cell that preserves the viability of M. leprae. Recent studies have determined that 33° C is permissive for maintenance of short-term M. leprae viability in axenic medium. Using this information, we developed a Schwann cell infection model that preserves the metabolic activity of M. leprae for up to 3 weeks in cultures, maintains functional abilities of Schwann cells to interact with neurons in culture and mimics cooler temperature areas where infection is observed in patients. When this model was used to study the impact of M. leprae infection on Schwann cells, Schwann cells had altered interactions with other Schwann cells and altered gene expression encoding several important adhesion molecules such as neural cell adhesion molecule (NCAM), neural-cadherin (N-cadherin) and glial fibrillary acidic protein (GFAP). However, M. leprae-infected Schwann cells were able to align and associate with neurons in culture, proliferate along these neurons and subsequently produce myelin in a manner comparable to control cultures. Established myelinated Schwann cell/neuron co-cultures, maintained at 33° C, did not demonstrate any apparent alterations in Schwann cell/neuron interactions nor myelin architecture due to M. leprae infection. These results indicate that M. leprae infection at the multiplicity of infection used for these studies does not appear to have detrimental effects on Schwann cell functional capabilities in the peripheral nerve. Therefore, the neuropathy observed in leprosy is most likely due to an aggressive immune response to infection within the nerve and not direct effects of M. leprae upon the Schwann cell.

▼ Questions about the clinical significance of an antimicrobial resin used on personal respirators led to the need for a system to generate consistent test bioaerosols for use in animal studies. The hypothesis was proposed that an aerosol delivery system based on the Collison nebulizer can be designed and engineered to provide, at selectable concentrations, a respiratory challenge of bioaerosol particles that is verifiably consistent in time and that can be fed in separate experiments through treated and untreated control filters to deliver a consistent challenge to a small-animal
model of human respiration. To verify this hypothesis, such an experimental filtration system was designed and built. Challenge trials were performed with MS2 bacteriophage and Bacillus atrophaeus. Over 30 to 40 minutes, the particle size distribution (PSD) was measured, and
viability of microorganisms collected in All-Glass Impingers (AGI-4s) was determined. Concentrations of particles and microorganisms downstream of the filter were too low to measure, and the viable counts for MS2 bacteriophage were not measured at all owing to problems with the assay method. However, in each experiment, the coefficients of variations (CVs) of time-series measurements of the total particle count, count median diameter, and geometric standard deviation of the upstream PSD were less than 10%. From five B. atrophaeus experiments with
viability data, all CVs of time-series measurements of upstream viable airborne concentration were less than 26%. This CV is somewhat higher than has been reported in the literature for tests with airborne Bacillus spores, but the plating method used to measure the
viability may have introduced additional variation that was not caused within the system itself. It can be reasoned based on this data that the system can provide a sufficiently steady aerosol challenge to be used for later studies using a small-animal
model of human respiration. The system provides a design for an animal exposure system incorporating aerosol filtration, which is a capability previously unreported in the literature. ( en )
