Modeling reinforced concrete cracking due to corrosion with a fracture mechanics approach
Creators: name: Tian, Xiaoping
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2006
Subjects: subject: Engineering, Civil.

description: With the increasing need of developing service life models for corrosion-induced damage in reinforced concrete structures, there has been a movement to model the concrete cover as a thick-wall cylinder subjected to an internal pressure due to corrosion products accumulation on the reinforcing steel. These models allow determining the amount of corrosion product necessary to initiate and propagate cracks along the cover. The first generation of models assume that concrete behaves linearly elastic and that the concrete cover does not have any residual tensile capacity once the tensile strength of the concrete has been reached. More advanced models include the softening behaviour of concrete beyond cracking initiation. This thesis proposes such a model wherein the state stress of the concrete cover due to accumulation of corrosion products is determined by analyzing an equivalent thick-wall cylinder subjected to a uniform internal pressure. Concrete is assumed to be an isotropic material, and deformations due to Poisson's ratio are ignored. To describe the behaviour of concrete in the softening region, a linear relation of stress versus displacement and a constant strain field are assumed. Mathematical expressions that determine the state of stress due to corrosion build-up at any point in the concrete cover are obtained by integrating the softening equations along the concrete cover. Analytical models for cracking initiation as well as longitudinal cracking of the concrete cover are formulated for both unconfined and confined conditions. The latter are the result of the presence of shear stirrups or tie/spiral reinforcement. To determine the validity of these models, their results are compared to published experimental data and finite element analyses. Finally, a parameterc analysis using the models is carried out in order to establish the role of significant model parameters on the resulting state of stress of the concrete cover and the associated damage.

description: Bill C-41, the Sentencing Reform Act became law on September 3, 1996. The legislation represents the culmination of nearly two decades of sentencing reform efforts. The conditional sentence of imprisonment, one of the Bill's provisions, is the focus of this thesis. The conditional sentence represents Parliament's response to Canada's high incarceration rate. This research examined the application of conditional sentences across the province of Ontario during the first fifteen months of its implementation. The basis of this analysis of conditional sentences is a data set of 4,633 conditional sentence orders imposed between September 1996 and November 1997. The sentencing data are complemented by an analysis of the case law from four Appellate Courts. Finally, a number of interviews were conducted with judges and crown prosecutors from Ottawa and Toronto in order to elicit their perceptions about conditional sentences. The findings present a portrait of the early application of the sanction in Ontario. (Abstract shortened by UMI.)

description: The Vitamin-A-metabolite retinoic acid (RA) acts as a master regulator of cellular programs. Mast cells (MCs) are primary effector cells of type-I-allergic reactions. We recently uncovered that human cutaneous MCs are enriched with RA network components over other skin cells. Yet, direct experimental evidence on the significance of the RA-MC axis is limited. Here, skin-derived cultured MCs were exposed to RA for seven days and investigated by flow-cytometry (BrdU incorporation, Annexin/PI, FcεRI), microscopy, RT- qPCR, histamine quantitation, protease activity, and degranulation assays. We found that while MC size and granularity remained unchanged, RA potently interfered with MC proliferation. Conversely, a modest survival-promoting effect from RA was noted. The granule constituents, histamine and tryptase, remained unaffected, while RA had a striking impact on MC chymase, whose expression dropped by gene and by peptidase activity. The newly uncovered MRGPRX2 performed similarly to chymase. Intriguingly, RA fostered allergic MC degranulation, in a way completely uncoupled from FcεRI expression, but it simultaneously restricted MRGPRX2-triggered histamine release in agreement with the reduced receptor expression. Vitamin-A-derived hormones thus re-shape skin-derived MCs numerically, phenotypically, and functionally. A general theme emerges, implying RA to skew MCs towards processes associated with (allergic) inflammation, while driving them away from the skin-imprinted MCTC (“MCs containing tryptase and chymase”) signature (chymase, MRGPRX2). Collectively, MCs are substantial targets of the skin retinoid network. View Full-Text
An examination of the relationship between harsh discipline in childhood, later punitiveness toward children and later ratings of adjustment

Child Abuse & Neglect

description: The present study was an investigation of the multigenerational hypothesis of child abuse, which suggests that abused children will become adults who abuse their own children. On the basis of responses to a questionnaire about childhood family experiences, five distinct groups of young adults from predominantly middle socioeconomic class families were identified: (1) adults who were abused in childhood and who labelled themselves abused; (2) adults who were abused in childhood but who did not label their disciplinary experiences abusive; (3) adults who were not abused in childhood but who had an abused sibling; (4) adults from nonabusive families who experienced mild physical discipline in childhood; (5) adults from nonabusive families who never experienced physical discipline. An interactive analogue disciplinary task was adopted to assess the disciplinary strategies utilized by the subjects and the amount of annoyance they experienced, when confronted with behavioral difficulties of five simulated children. Also, the level of depressed and fearful feelings experienced by the subjects was assessed. Based on the multigenerational hypothesis, it was expected that individuals who were abused or who had an abused sibling would use more physical discipline and sooner, and would yell and threaten more, than individuals from nonabusing families. It was also expected that subjects from abusive families would feel more annoyed with the children, and would report higher levels of depressed and fearful feelings than the subjects from nonabusive families.
description: The results of the present study did not support a simple multi- generational hypothesis of child abuse: the groups did not differ on the dependent variables in any of the overall analyses, and only a few planned comparisons showed statistically significant group differences, which was not beyond that which would be expected by chance. However, males reported significantly more annoyance than females, when confronted with difficult child behaviors, and tended to select more physical discipline choices in the analogue parenting task. Also, a significant positive correlation was obtained, across the entire sample, between how annoyed the subjects felt when confronted with difficult child behaviors and how much physical discipline they utilized with the children. These results are discussed.

description: Persistent changes in land use, coupled with changes in hydrology, have significantly increased flood risk in the US. Traditional flood risk assessments focus on structural vulnerability and risk, giving limited attention to agricultural risk and social vulnerability. The absence of agricultural flood risk assessment at the national scale impedes understanding of the magnitude of flood impacts. Social vulnerability to floods is often studied by applying generic social vulnerability indicators across different types of flood impacts. However, there is still limited understanding of specific groups of the population that are most vulnerable to flood impacts. The characteristics of vulnerable populations can vary significantly based on the type of flood loss. On a local scale, flood mitigation measures largely focus on structural interventions, such as floodproofing. There is inadequate attention to non-physical needs such as health, social, and economic needs, which if unmet, reduce mitigation effectiveness.
description: The dissertation employs three studies to improve the understanding of flood risk and social vulnerability in the US. The first study uses flood loss estimation modeling to calculate the average annual loss for agriculture in the US. This study incorporates a broader set of contributing factors than employed in previous studies of agricultural flood loss. The second study tests the relationship between flood loss and social vulnerability using spatial regression models for structural and agricultural flood loss at a national scale. The third study identifies the social vulnerability pathways to the reduction of unmet needs during household flood mitigation using Qualitative Comparative Analysis methodology.
description: The estimated average annualized loss in the contiguous US is $546.84 million, with higher losses concentrated in the corn and soybean belt of the Midwest and Mississippi River Basin. Spatial analysis of social vulnerability and flood loss identified that for higher structural losses, the indicators of median house value, unoccupied housing units, and renter populations are the most explanatory. Meanwhile, for agricultural losses, employment in extractive industries, Asian populations, and civilian unemployment were the most explanatory factors. At the local scale, within a cohort of socially vulnerable households, those with fewer social vulnerability characteristics had the strongest causal pathways to successful reduction of unmet health and social needs. Collectively, the findings from this dissertation help inform the development of more equitable and effective flood mitigation.
Extrinsic aids and the interpretation of statutes.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1990
Subjects: subject: Law.

description: This thesis considers a question of increasing significance in Canada today--the use of extrinsic aids in the interpretation of statutes. The thesis argues that the principles adopted by the courts that allow the admission of certain aids to interpretation for limited purposes only and that do not allow the admission of legislative history in non-constitutional cases create artificial distinctions amongst the various different types of aids. These distinctions serve to obscure rather than elucidate the process of interpretation by the courts. There are no compelling reasons for the courts to reject outright the admission of legislative history in non-constitutional cases. Parliamentary materials should therefore be admissible in accordance with the same rules as those applied to other interpretative aids. To this end, the thesis examines some of the interpretative aids used by the courts and the way in which they are used. Part I examine some of the aids found in the printed version of the statute. Part II examines a group of aids that have been classified as part of the general knowledge and experience of the judge. Part III looks at the way in which the courts use related acts and treaties whilst Part IV deals with the contentious area of legislative history, including Commission reports.

Subjects: subject: Biology, Cell.

description: With the aim of increasing our plant knowledge of Frankia, we have investigated the structure of the ribosomal RNA genes from Frankia sp. strain AcN14a. A genomic library was constructed in EMBL3 and two types of clones, each containing a different set of rRNA genes, were identified by restriction analysis. The rRNA genes of Frankia AcN14a have been compared to those of E. Coli and other eubacterial species. Frankia AcN14a rRNA genes show over 98% idenity to those of Frankia ORS020606 and usually show over 80% identity to other actinomycete rRNA sequences. The mature 16S, 23S and 5S rRNAs are predicted to contain 1509, 3105 and 120 nucleotides, repectively. Thus, Frankia 16S rRNA is smaller than that of E. coli whereas the 23S rRNA of Frankia is longer than it E. coli counterpart. In spite of these size differences, all three rRNAs could be folded into secondary structures similar to the E. coli models and most tertiary interactions proposed for E. coli rRNAs could be formed in Frankia AcN14a 16S and 23S rRNAs. Finally, the potential usefulness of rRNA RFLP analysis for the categorization of Frankia isolates has been investigated. Hybridization of both 16S and 23S rDNA specific probes to total DNA digested with BamH1, revealed sufficient polymorphism to allow classification of twenty-six isolates into six groups (A to F). In addition, eight other isolates exhibit unique patterns. (Abstract shortened by UMI.)
Earthworks: Shamanism in the religious experiences of contemporary artists in North America.

description: Within the last 30 years a number of earthworks have been built by artists, primarily in North America, but extant examples are known elsewhere in the world. These artworks are not intended to be bought and sold or displayed within the usual gallery-focused art distribution system. They are site-specific works, often located in remote, hard-to-reach areas. Curatorial documentation is sometimes incomplete. Some artists do not even list their earthwork projects on their resumes. What than is the purpose of the contemporary earthworks? Are the contemporary works religious statements of sacral orientation? 203 questionnaires were sent to artists throughout North America whose work seemed to show an especial interest in earthworks, visionary experiences, and/or nature. Questions were asked of the artists concerning visionary experiences, paranormal experiences, life crises, religious background and current religious affiliation, among other things. Subsequent interviews were conducted with 19 artists. For most of the artists in the group their visions and paranormal experiences inspire and authenticate their work as artists, work which they themselves believe to be "healing" and linked to the earth as sacred, a world in which they frequently encounter "sacred places," power centers, and other experiences of mana or kratophany. In very special ways, the artists feel themselves to be mediums for a sacred knowledge which they believe comes from nature, from the earth, from the energies of all life, of all time--but not from god or gods per se. The artists appear to perceive the world as a self-contained whole, a healing whole, and in their art they take part in that healing whole. Thus, the dissertation argues that the analogy of shaman as artist (artist as shaman) is a useful one to make to explicate the religious experiences of artists; that artists can be studied as a group using the statistical profile methods of social sciences; and that contemporary earthworks may constitute a hitherto unrecognized body of sacred art.

description: Synovial injury and healing are complex processes including catabolic effects by proinflammatory cytokines and anabolic processes by anti-inflammatory mediators. Here we examined the expression of pro- versus anti-inflammatory mediators in synovium of patients with diagnostic arthroscopy (control), joint trauma (JT), osteoarthritis (OA), and rheumatoid arthritis (RA). Synovial samples from these patients were subjected to RT-PCR and double immunofluorescence confocal microscopy of pro- and anti-inflammatory mediators as well as immune cell markers. Interestingly, pro- and anti-inflammatory mediators were expressed predominantly in granulocytes in patients with JT and in macrophages, lymphocytes, and plasma cells in patients with OA and RA. Interestingly, parallel to the severity of inflammation, proinflammatory mediators IL-1β, TNF-α, and 5-LOX specific mRNA as well as immunoreactive (IR) cells were significantly more abundant in patients with RA and JT than in those with OA. However, anti-inflammatory mediators 15-LOX, FPR2, and IL-10 specific mRNA as well as IR cells were significantly more abundant in patients with OA than in those with JT and RA. These findings show that upregulation of proinflammatory mediators contributes to the predominantly catabolic inflammatory process in JT and RA synovium, whereas upregulation of anabolic anti-inflammatory mediators counteracts inflammation resulting in the inferior inflammatory process in OA synovium.

description: Australia's broadband future has the potential to realise tangible benefits for consumers living with disability. This paper discusses the importance of bridging the digital divide between Australia's disabled and non-disabled consumers, the role that broadband industry standards can play in bridging this divide and the importance of including people with disability in the development and promotion of best practice standards for broadband products and services. The paper argues that through implementation of best practice 'access-for-all' standards for broadband products and services, which have been developed in consultation with end-users with disability, the implementation of a ubiquitous broadband network will help bridge this digital divide and provide Australians living with disability increased inclusion and participation in all aspects of Australian society.
Francisella Tularensis infection uncovers a link between neutrophil metabolism and apoptosis

description: Francisella tularensis is the etiological agent of tularemia, one of the most infectious pathogens known and one of few pathogens capable of infecting host neutrophils (polymorphonuclear leukocytes; PMNs). PMNs are vital innate immune cells that undergo constitutive apoptosis 24 hours after entering circulation, and disruption of this tightly regulated process leads to an impaired immune response that is incapable of resolving infection. Our laboratory discovered that Francisella tularensis delays human PMN apoptosis by inhibiting the intrinsic, extrinsic, and phagocytosis-induced cell death pathways, but the mechanisms by which this is achieved are not fully understood.
description: We demonstrate here that metabolic reprogramming of neutrophils, including induction of glycolysis, is an important and previously unappreciated aspect of neutrophil longevity. Specifically, our data indicate that Francisella-infected PMNs released significantly more lactate and upregulated expression of genes encoding glucose transporters and 10 of 11 glycolytic enzymes. Direct measurements made using a Seahorse XF analyzer demonstrate that glycolysis (measured as the extracellular acidification rate) nearly quadrupled, and glycolytic capacity doubled by 12 hours after Francisella infection. Inhibition of glycolysis or glucose uptake using 2-deoxy-D-glucose or WZB-117 blocked the ability of Francisella tularensis to delay PMN apoptosis, thus confirming that these processes are mechanistically linked. Intriguingly, Francisella-infected PMNs also contained significantly more glycogen than their uninfected counterparts. Furthermore, inhibition of glycogen breakdown with the glycogen phosphorylase inhibitor CP-91149 was sufficient to delay uninfected PMN apoptosis and significantly enhanced the apoptosis delay in Francisella-infected PMNs. Finally, we show that treating PMNs with the pan-caspase inhibitor Q-VD-OPH not only caused delayed apoptosis, but also significantly upregulated glycolysis and glycogen content, further supporting the hypothesis that PMN metabolism and lifespan are fundamentally linked.
description: p38 mitogen-associated protein kinase (MAPK) and class IA phosphoinositide-3 kinase (PI3K) influence PMN lifespan in a stimulus-specific manner, and also have established roles as glycolytic regulators. Our laboratory demonstrated that inhibition of p38 MAPK or PI3K signaling blocks Francisella-mediated apoptosis delay, and we hypothesize that Francisella-mediated glycolytic upregulation is mechanistically linked to extension of PMN lifespan by host p38 MAPK and PI3K signaling.
IRF6 regulates the recycling of E-cadherin at the cell membrane

Subjects: public abstract

description: Cellular adhesions are essential structures mediating tissue integrity as well as numerous cellular processes, including migration and stratification. Consequently, any disruption in the dynamic of these protein complexes lead to severe defects. Therefore, understanding the molecular regulation of cellular adhesions is imperative. Interferon regulatory factor 6 (IRF6) is a master regulator of epidermal migration and differentiation, yet how it affects cellular adhesions is not known. In the present study, we take advantage of keratinocytes in culture. Using this in vitro model, we determined that IRF6 is necessary for the proper assembly of adherens junctions, tight junctions and desmosomes. Particularly, IRF6 is required for proper levels at the membrane of one of the components of adherens junctions, E-cadherin. We demonstrated that it is the recycling of E-cadherin, and not its endocytosis, that is affected by IRF6. To further explore the molecular mechanism by which IRF6 mediates recycling of E-cadherin at the membrane, we evaluated the requirement of the protein binding domain (PBD) and the DNA binding domain (DBD) of IRF6 in the regulation of cellular adhesions. We demonstrated that the PBD of IRF6 is necessary and sufficient for the recycling of E-cadherin. Furthermore, we performed mass spectrometry analysis to define the interactome of IRF6 and to identify the effector proteins acting downstream of IRF6 in the regulation of E-cadherin recycling. We show that IRF6 forms a complex with E-cadherin as well as with Rab11 in recycling endosomes, and the formation of this complex facilitates the exit of E-cadherin from the endosomal pathway towards the cell membrane. Thus, we define a non-canonical role for IRF6 in the regulation of cellular adhesions that requires its interaction with cytoplasmic effector proteins.

description: The adsorption of ethylhexadecyldimethylammonium bromide (EHDA-Br) at liquid-air interfaces generated by bubbling a constant stream of air through an aqueous solution was determined with a 2 in. diameter foram separation column equipped with a gas sparger made of porous stainless steel (20mu pores). The results obtained from batch operation with total recirculation of the collapsed foam as well as from continuous operation showed that the surface excess Gamma depends on foam rate as well as bulk concentration whereas Gibbs' adsorption isotherm predicts a constant value for Gamma. It was concluded that the application of Gibbs' equation to the prediction of the surface excess accumulated at dynamic interfaces generated in the foam separation process for EHDA-Br is probably justified only under the rather stringent conditions of good drainage and perfect stability of the foam. Equations proposed to predict the performance characteristics of a continuous pool-feed foam separation column based on Gibbs' equation and an ideal foam model were also found to be valid under the same conditions. The effect on the various parameters describing the efficiency of a continuous foam separation column was studies for the following variables: feed concentration, foam column height, feed rate, column diameter. An attempt was also made to analyze the continuous foam separation process by utilizing the concept of the HTU.

description: This thesis considers smart wireless power transfer (WPT) systems. This type of WPT system is defined by its ability to adapt to a wide range of arbitary operating conditions, and its ability to perform complex proceedures autonomously.
description: This research specifically focuses on smart WPT systems that combine the use of multiple transmitting coils and the use of high-Q resonance to achieve enhanced range and performance. We consider an inductive WPT system where a number of transmitting coils seek to transfer the maximum possible amount of power to a receiver. This system consists of the transmitting and receiving coils which are designed to self-resonate with high-Q at a common frequency. We consider closed optimization for constraints that may be of interest when controlling WPT systems i.e., drive voltage limitations, loss minimization, and nullforming.
description: While substantial literature exists on WPT systems using both multi-coil transmitters and coupled resonance, previous work has been limited to small-scale and simple transmitters. This limitation can be attributed to the difficulty of constructing models which adequately predict the behavior of these more complex physical systems. The ability to construct physically accurate models is needed in analyzing and optimizing such systems.
description: Our key novelty is to use receiver feedback to avoid the need for such models. This simple and powerful idea opens up the possibility of WPT systems consisting of a large number of resonant coils that may be diversely coupled with one another.
description: In this work, theoretical and experimental results on the properties of such multi-coil resonant WPT systems are presented. Theoretical results that generalize the well-known phenomenon of frequency-splitting to a system with multiple transmitters are analyzed. A simple adaptive approach to optimizing such a system and experimental results to illustrate the benefits of multi-coil resonance in the total power delivered are presented. A simple heuristic method of performing phase estimation from power-only measurements is discussed, and various closed-form solutions to optimization problems that are of interest when controlling WPT systems are derived.
description: Lastly, an experimental setup that can automatically perform various optimization procedures is described in detail. The system implements receiver feedback to automatically estimate the current context of WPT system's geometry and circuit parameters. This WPT system is used as a demonstration of a multiple-input multiple-output system with resonant coils that can be controlled in real-time to precisely maximize or null power to selected receivers. We also show through heuristic methods that such a system can adaptively maximize power to a changing target.

description: In 2001, the European Commission introduced a risk assessment project known as FOCUS (FOrum for the Coordination of pesticide fate models and their USe) for the surface water risk assessment of active substances in the European Union. Even for the national authorisation of plant protection products (PPPs), the vast majority of EU member states still refer to the four runoff and six drainage scenarios selected by the FOCUS Surface Water Workgroup. However, our study, as well as the European Food Safety Authority (EFSA), has stated the need for various improvements. Current developments in pesticide exposure assessment mainly relate to two processes. Firstly, predicted environmental concentrations (PECs) of pesticides are calculated by introducing model input variables such as weather conditions, soil properties and substance fate parameters that have a probabilistic nature. Secondly, spatially distributed PECs for soilŃclimate scenarios are derived on the basis of an analysis of geodata. Such approaches facilitate the calculation of a spatiotemporal cumulative distribution function (CDF) of PECs for a given area of interest and are subsequently used to determine an exposure concentration endpoint as a given percentile of the CDF. For national PPP authorisation, we propose that, in the future, exposure endpoints should be determined from the overall known statistical PEC population for an area of interest, and derived for soil and climate conditions specific to the particular member state. © 2016 Society of Chemical Industry

The game language setting was Russian, and the participants were playing, completing the prompt tasks and describing in Russian events on the screen and discussing grammar and vocabulary. After each session, each participant completed a written reflection activity. Two posttests and a semi-structured interview concluded the study.
description: Both individual participants and dyads were units of analysis. The study was situated within the theoretical framework of CHAT (Cultural-Historical Activity Theory, Engestrom, 2005; Leont’ev, 1978). Participants started the activity of gameplay with their own unique perspectives, and during gaming sessions they either arrived at joint understanding of Russian motion verbs by creating a joint Object, or their individual perspectives remained unchanged (in non-collaborative dyads, Storch, 2002).
description: The results showed that learners’ perceptions and knowledge improved for the most part, with few exceptions based on individual differences (proficiency level, motivation, and goals of study). The analysis of patterns of dyadic interaction (Storch, 2002) revealed that certain types of engagement between participants deemed more beneficial for creating joint understanding (that leads to learning) than others (Engestrom, 2005). Therefore, collaborative and expert/novice pairings facilitate learning whereas the presence of a dominant partner in a pair inhibits learning. Finally, The Sims successfully mediated learning of L2 Russian verbs of motion (as well as vocabulary and other grammar) in a variety of ways and proved to be a viable resource for learning and teaching L2 Russian verbs of motion.

description: Swarms, of diabase dikes have been reported in all Provinces of the Precambrian Shield. One of these is the Buckingham swarm which extends into the region of the Gatineau Park. A fresh exposure of one of these dikes was sampled to study ids petrographic and chemical characteristics and any variations which might reflect the nature of its formation. The physical and chemical characteristics of the dike compare closely to those of Hawaiian tholeiitic basalts, and the sub-ophitic texture of this dike resembles that of typical diabase dikes. The dike appears to be a member of a swarm of diabase dikes of probable Ordovician age, and are located in the Grenville province of the Canadian Shield. Some variations in composition exist across the dike. (a) Mafic minerals decrease in quantity inward while plagioclase increases inward. (b) Grain size graphs plot in the shape of a bell curve, rather than parabolic. (c) The characteristic sub-ophitic texture is replaced by porphyritic texture in the contact samples. (d) An content of plagioclase decreases inward. (e) Silica content of bulk rocks decreases outward. (f) Rock compositions appear to have erratic variation in the zones near the contacts. The observed variation in texture and chemical composition within the study dike may be attributed to a combination of factors including; contamination, secondary alteration, and some form of differentiation.

description: Background Total body irradiation (TBI) has been part of standard conditioning regimens before allogeneic stem cell transplantation for many years. Its effect on normal tissue in these patients has not been studied extensively. Method We studied the in vivo cytogenetic effects of TBI and high-dose chemotherapy on skin fibroblasts from 35 allogeneic stem cell transplantation (SCT) patients. Biopsies were obtained prospectively (n = 18 patients) before, 3 and 12 months after allogeneic SCT and retrospectively (n = 17 patients) 23–65 months after SCT for G-banded chromosome analysis. Results Chromosomal aberrations were detected in 2/18 patients (11 %) before allogeneic SCT, in 12/13 patients (92 %) after 3 months, in all patients after 12 months and in all patients in the retrospective group after allogeneic SCT. The percentage of aberrant cells was significantly higher at all times after allogeneic SCT compared to baseline analysis. Reciprocal translocations were the most common aberrations, but all other types of stable, structural chromosomal aberrations were also observed. Clonal aberrations were observed, but only in three cases they were detected in independently cultured flasks. A tendency to non-random clustering throughout the genome was observed. The percentage of aberrant cells was not different between patients with and without secondary malignancies in this study group. Conclusion High-dose chemotherapy and TBI leads to severe chromosomal damage in skin fibroblasts of patients after SCT. Our long-term data suggest that this damage increases with time, possibly due to in vivo radiation-induced chromosomal instability.

description: Without widespread and immediate changes in human values and activities, massive tracts of natural habitat will be degraded to the detriment of those ecosystems, ecosystem services, and many threatened taxa—in the oceans and elsewhere. Despite this, the conservation movement has yet to devote much attention to the intentional project of widespread norm change. By one logic, the ecosystem services concept offers a means of integrating meaningful conservation into decision-making by diverse government and corporate actors, potentially normalizing conservation. But normalizing conservation would require not only the uptake of ecosystem-services concepts but also widespread changes in conservation practice and stewardship values—on a scale that far exceeds what we have witnessed to date. The concept of ecosystem services has potential for assisting such a societal transformation because it effectively puts a human face on environmental change, thereby enabling the extension of responsibility and morality into environmental arenas at all scales. Furthermore, cultural ecosystem services merit particular attention because of their contribution to the formation of attachments to particular places and to identities rooted in nature and conservation, which presents an opportunity to consolidate and shape deep motivations for lasting conservation. Realizing these two opportunities in a way that is both appropriate and effective, however, will require several important innovations and new institutions, which we propose here. One key step is to enlist a broad base of consumers and corporations in the funding of actions to mitigate the environmental impacts associated with their participation in global supply chains, via funding vehicles that are conspicuous, easy, enjoyable, and not too expensive. We describe a new initiative called CoSphere that strives to create such structures. With consolidated effort and explicit attention, conservation can become normalized—to the benefit of current people, future generations, and life on Earth.
