description: Twenty-one trilobite species belonging to 16 genera and subgenera, 11 families and seven orders are systematically documented from the uppermost Ordovician and the lowermost Silurian strata (upper Hirnantian–Rhuddanian) at three sections in north-eastern Yunnan and northern Guizhou provinces, south-west China. Together with those trilobites previously reported from the Yanping section of northern Guizhou, these trilobites constitute the earliest known recovery trilobite faunas in South China after the Late Ordovician mass extinction (LOME) and are characterized by the Silurian-type Sinoencrinurus gen. nov. and Ciliscutellum faunas. Two new genera (Sinoencrinurus gen. nov. and Yunnanoproetus gen. nov.) and four new species (Ciliscutellum rhaxerosides sp. nov., Meadowtownella yunnanensis sp. nov., Batocara tuberosus sp. nov. and Yunnanoproetus shanshuensis gen. et sp. nov.) are described. The monophyly of Sinoencrinurus gen. nov. is well supported by the results of phylogenetic analysis, and it may form a sister group to Coronocephalus. Two genera, Meadowtownella and Batocara, have their first records in South China. Supported by evidence from faunal composition, lithology and numerical analyses, six trilobite associations are recognized along environmental gradients from nearshore to inner shelf. These associations had prominent ecological differentiation and strong endemicity to South China. Their ecological differences and distribution were mainly controlled by oxygen levels, depth gradients and substrate conditions. The mode of life and environmental tolerance of different trilobite taxa may also be part of the controlling factors. https://zoobank.org/urn:lsid:zoobank.org:pub:8B5C65ED-9523-4ACD-ABD4-86EE01127975

description: The Way of Sinners is a collection of short stories united by place and themes. The stories, most of which are told in first-person, take place in fictional and real towns around Virginia, in Tidewater, the Shenandoah Valley and the western part of the commonwealth, near Blacksburg. The stories concern women and girls who feel they have failed, who fear they cannot be redeemed. The characters want to be restored to dignity — to be whole again, good. Human nature stands in their way. The characters are keenly aware of slights and sins committed by and against them, and as they muddle through their lives, they seek to square their perceptions of themselves with reality.
Sensemaking processes and stakeholders' reactions to IT implementation
Creators: name: Rahighi, Amir
Publisher: name: Swinburne
Year: 2024

description: This research investigates how sensemaking activities of stakeholders influence and shape their reactions to change during IT implementation. It seeks to derive insights into the role and influence of stakeholders’ relationships and interactions on developed responses and reactions. The findings of this research suggest that stakeholders’ sensemaking processes are consonant or dissonant, involving and leading to complex and dynamic feelings, attitudes and behaviours towards change from positive and supportive to negative and resistive. This research also offers practical suggestions for preventing or mitigating dysfunctional impacts of resistance more effectively and promoting stakeholders’ engagement and commitment to change.

description: Background To evaluate the current status of prospective interventional clinical trials that includes brachytherapy (BT) procedures. Methods The records of 175,538 (100 %) clinical trials registered at ClinicalTrials.gov were downloaded on September 2014 and a database was established. Trials using BT as an intervention were identified for further analyses. The selected trials were manually categorized according to indication(s), BT source, applied dose rate, primary sponsor type, location, protocol initiator and funding source. We analyzed trials across 8 available trial protocol elements registered within the database. Results In total 245 clinical trials were identified, 147 with BT as primary investigated treatment modality and 98 that included BT as an optional treatment component or as part of the standard treatment. Academic centers were the most frequent protocol initiators in trials where BT was the primary investigational treatment modality (p
Reinvestigating the Interaction of Search and Presence of Meaning in Life on Depressive and Anxiety Symptoms with Tripartite Model of Meaning
Creators: name: Jiang, Weiran
Publisher: name: Brandeis University
Year: 2024

description: Meaning in life is linked to individuals' well-being. Existing research has generated mixed findings, suggesting that people who search for meaning in life and have a limited sense of meaning tend to experience higher depressive and anxiety symptoms. Recently, there has been a rise in the popularity of the tripartite model of meaning in life, encompassing purpose, comprehension, and mattering as the three subcomponents of meaning. The current study aims to investigate the effect of the interaction between the search for meaning (SML) and the presence of meaning (PML) on depressive and anxiety symptoms using this tripartite framework. Additionally, this study explored whether philosophical meaning in life and the reported behavior of meaning searching are associated with those emotional symptoms. The sample included 139 participants who completed measures of meaning in life (MLQ, MEMS, LRI-framework), depressive symptoms (BDI-II), and anxiety symptoms (BAI) and reported their meaning-searching behavior. Results show that PML, measured by both MLQ and MEMS, was negatively related to depressive and anxiety symptoms. Unexpectedly, SML was not related to emotional symptoms, and it interacted with PML measured by MEMS but not by MLQ in relation to emotional symptoms. Our findings suggest that SML may not relate to poor mental health, and further research is needed to explore under what circumstances that holds true.
Apoptosis in the adult goldfish pituitary

description: This thesis research characterized apoptosis in the adult goldfish pituitary. Apoptosis is a form of programmed cell death that plays key roles in many biological processes by selectively removing old or unwanted cells. Morphological and biochemical signs of apoptosis established its presence within the gland. The pituitary gonadotrophs secrete gonadotropin-II to regulate sex steroid production, ovulation and sperm production. It was possible to combine TUNEL with immunocytochemistry and demonstrate apoptosis in gonadotropin-II positive cells in the pars distalis of the pituitary, allowing for the fist time the identification of apoptotic gonadotrophs in situ. Other studies suggest that pituitary cell populations and function fluctuate through the seasonal reproductive cycle. Apoptosis could play a role in regulating secretion by regulating the cell number. Treatments with the dopamine agonist apomorphine, and with a gonadotropin-releasing hormone agonist failed to modulate the apoptosis levels measured by DNA laddering or by TUNEL. Finally, this study demonstrated that the calcium ionophore A23187, significantly increases apoptosis in whole pituitary gland cultures. These studies established a new method to identify apoptotic hormone-secreting cells.

Evaluation of a mental skills training program implemented by an elementary classroom teacher.
Creators: name: Bonadie, Jenelle N.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1995
Subjects: subject: Education, Tests and Measurements.

description: The purpose of this study was to implement Orlick's (1993) mental skills/life skills training program and assess the extent to which children (1) learned to relax themselves at will, (2) successfully implemented stress control strategies, and (3) improved the frequency of their highlights (any simple pleasure, joy, or other positive experience that improves the quality of one's day). Two intact classes of grade 2 children took part in the study. One class served as the experimental group, while the other class served as the control group. The usual classroom teacher delivered the program 4 to 5 times per week, for 9 consecutive weeks. Each intervention session was 10 to 15 min in length. Significant positive effects were found in the experimental group with respect to the children's abilities to lower their heart rates at will and successfully implement relaxation and stress control strategies in their daily lives. Children in the experimental group also experienced a significant increase in the frequency of their highlights over the course of the intervention period. The results suggested that children in grade 2 can (1) learn to relax themselves at will as measured by heart rate, (2) successfully implement stress control strategies, and (3) improve the frequency of their highlight experiences when the usual classroom teacher delivers Orlick's (1993) mental skills training program.
Towards an organizational planning system design: Implications for regional planning.
Creators: name: Lemire, Jean-Marc.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1978
Subjects: subject: Operations Research.

description: The purpose of the thesis is to explore the design of a planning system applicable to any formal organization. To do this, issues which are related to planning systems of various types (corporate, voluntary, public) are examined in chapter I. In order to take these issues into account, the chapters II and III indicate that the concepts of system and of design should be better understood. This provides tentative guidelines for the design of systems applicable to the management of organizations (chapter IV). These first four chapters make up the first part of the thesis and provide a review of some of the basic concepts which are needed to formulate a planning system of the type envisaged. The second part of the thesis essentially describes the various components of the planning system using the guidelines and concepts provided in the first part. In chapter V, an overview of the system is provided while chapters VI, VII and VIII focus on three aspects of the planning system. Chapter VI, 'Planning Operations,' essentially revises already provided steps of the planning process and chapter VII provides guidelines for 'planning authority and responsibilities' which do not appear to have been extensively discussed in previous literature on planning systems. As a conclusion, chapter VIII presents a series of implications of a general planning system for regional planning theory and practice.
Factors affecting Athabasca oil sand sludge stability.
Creators: name: Lynds, Maurenia Mae.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1992
Subjects: subject: Engineering, Chemical.

description: The two major oil sand extraction plants, Syncrude Canada Ltd. and Suncor Inc., utilize the Clark Hot Water Extraction Process to remove bitumen from surface mineable Athabasca oil sands. This process produces a waste stream containing dispersed clay, sand, silt, and bitumen which is pumped to tailings ponds. The coarse sand and some of the finer particles settle out and are used to construct containment dykes around the ponds. However, much of the clay, silt, and bitumen remain in suspension and are carried out towards the centre of the pond. These solids eventually form a sludge with a gel-like structure, retaining from 85 to 90 percent of the recyclable process water. The ever-increasing, enormous tailings ponds present a serious environmental hazard to the nearby lakes, rivers, land, and wildlife. It has been proven that ultrafine (10 to 200 nm) clay particles, capable of forming a highly porous, three-dimensional gel network, are the main components responsible for structure formation within Athabasca oil sand sludge. The ultrafine clay particles, mainly kaolinite and mica, are able to form the gel network in a short period of time (1 to 14 days) and the gel has a high water holding capacity. The oil sand sludge is also composed of coarse solids, poorly-crystalline inorganic components, and strongly-bound organic matter. The deuterium nuclear magnetic resonance technique was used to study the effect of these components, as well as, the effect of the different sizes of ultrafine clay particles on gel formation. It was observed that the gel forming propensity of the sludge was significantly increased with a decrease in particle size of the ultrafine clays. The presence of coarse solids slowed the rate of gel formation; however, the poorly-crystalline inorganic components were shown to have no effect on the gel forming propensity. The ultrafine clay particles were further separated into hydrophilic and biwetted solids. The biwetted ultrafine solids were identified as having surfaces that contained a large percentage of strongly-bound organic matter. The presence of these particles significantly accelerated the rate of gel structure formation. Lastly, water chemistry (chemical composition of dissolved matter) was proven to play a significant role in sludge structure formation. The ultrafine clay particles would only form a gel when the aqueous media contained an appropriate amount of dissolved electrolytes. Gel structure formation was prevented in an aqueous media of distilled water. As well, a significant increase in the electrolyte concentration of the aqueous media induced coagulation, thereby allowing a dense sediment to be formed and a large volume of trapped water to be released. These results have revealed that the combination of ultrafine clay particles and appropriate water chemistry is essential before structure formation can occur within oil sand sludge.

Determining the oncogenic activity of different Epstein-Barr virus proteins on the development of nasopharyngeal cancer
Creators: name: Kong, Ee Ling
Publisher: name: Swinburne
Year: 2024

description: Nasopharyngeal carcinoma is a highly metastatic cancer arising from the epithelium lining of the nasopharynx and has distinct geographical distribution and multiple etiological cofactors. Epstein-Barr virus infection is strongly associated with nasopharyngeal carcinoma and EBV genes products are believed to play an important role in the development of nasopharyngeal carcinoma. In this study, we examined the oncogenic activity of EBV genes products in normal nasopharyngeal epithelial cells. We found that two EBV genes products contribute greatly towards the proliferation and migration of the normal nasopharyngeal epithelial cells. Thus, such genes products may serve as the potential targets for NPC therapy.
Genetic diversity estimates and DNA fingerprinting of Canadian cultivars of durum wheat.

Subjects: subject: Agriculture, Agronomy.

description: Estimates of genetic diversity present in gene pools have important implications for breeders and germplasm curators. They constitute the raw material for plant improvement and can provide protection against genetic vulnerability to biotic and abiotic stresses. The purpose of this thesis was to derive Pedigree and Amplified Restricted Fragment Polymorphism (AFLP)-based Genetic Diversity Estimates (GDEPED and GDEAFLP, respectively) among all currently registered 13 Canadian durum wheat cultivars in order to test the hypothesis that the actual level of genetic variation at the DNA level is lower than what is measured from pedigree data. Two objectives were set in this thesis. The first objective was to estimate the genetic diversity level among cultivars using two independent methods namely AFLP and pedigree. The second objective of this thesis was to use cultivar-specific AFLP markers for identification of cultivars and transform these markers into sequence tagged site (STS) markers for routine identification of durum wheat cultivars.

description: Assigning function to orphan membrane transport proteins and prioritizing candidates for detailed biochemical characterization remain fundamental challenges and are particularly important for medically relevant pathogens, such as malaria parasites. Here we present a comprehensive genetic analysis of 35 orphan transport proteins of Plasmodium berghei during its life cycle in mice and Anopheles mosquitoes. Six genes, including four candidate aminophospholipid transporters, are refractory to gene deletion, indicative of essential functions. We generate and phenotypically characterize 29 mutant strains with deletions of individual transporter genes. Whereas seven genes appear to be dispensable under the experimental conditions tested, deletion of any of the 22 other genes leads to specific defects in life cycle progression in vivo and/or host transition. Our study provides growing support for a potential link between heavy metal homeostasis and host switching and reveals potential targets for rational design of new intervention strategies against malaria.
An efficient parallel optimization algorithm for the token bucket control mechanism

Year: 2004
Subjects: subject: Computer Science.

description: The Token Bucket algorithm, one of the most widely used control mechanism nowadays, has been widely studied to ensure the QoS needs of various applications. However, one main drawback of current models of this algorithm is that most of them have focused on a single Token Bucket system. In this thesis, based on previous research efforts, we propose a parallel solution to the multiple Token Bucket model. We also develop a Reduced Memory Algorithm to decrease the algorithm's memory requirements at the cost of extra computation time. We test our parallel processing algorithm using two sets of traces. Our numerical results show that the model can effectively solve the multiple Token Bucket problems. Besides showing the benefits of using a parallel processing platform, our results also provide us with the guidelines to configure the parallel processing platform.

description: Perception is an inferential process, which becomes immediately evident when sensory information is conflicting or ambiguous and thus allows for more than one perceptual interpretation. Thinking the idea of perception as inference through to the end results in a blurring of boundaries between perception and action selection, as perceptual inference implies the construction of a percept as an active process. Here we therefore wondered whether perception shares a key characteristic of action selection, namely that it is shaped by reinforcement learning. In two behavioral experiments, we used binocular rivalry to examine whether perceptual inference can be influenced by the association of perceptual outcomes with reward or punishment, respectively, in analogy to instrumental conditioning. Binocular rivalry was evoked by two orthogonal grating stimuli presented to the two eyes, resulting in perceptual alternations between the two gratings. Perception was tracked indirectly and objectively through a target detection task, which allowed us to preclude potential reporting biases. Monetary reward or punishments were given repeatedly during perception of only one of the two rivaling stimuli. We found an increase in dominance durations for the percept associated with reward, relative to the non-rewarded percept. In contrast, punishment led to an increase of the non-punished compared to a relative decrease of the punished percept. Our results show that perception shares key characteristics with action selection, in that it is influenced by reward and punishment in opposite directions, thus narrowing the gap between the conceptually separated domains of perception and action selection. We conclude that perceptual inference is an adaptive process that is shaped by its consequences.

description: Executive functioning (EF) shapes how we navigate everyday life and approach difficult tasks. Therefore, it is important to understand the factors that benefit or disrupt EF. One such factor is time pressure, the sense of having insufficient time to perform an action. Studies show that time limits reliably impair EF. However, little is known about how the perception of time pressure (PTP) alone, in the absence of real time limits, impacts cognitive processes like EF. Using a Flanker task to index the EF inhibition, I induced PTP by manipulating the duration of inter-trial intervals (ITIs) across the experiment. Specifically, I shortened ITIs to increase PTP and lengthened ITIs to decrease PTP. I found that PTP strongly impacted task performance, with increasing PTP fomenting distress and impairing inhibitory control. Decreasing PTP reversed these effects. In conflict with the Attentional Control Theory (Eysenck et al. 2007), baseline test anxiety did not affect performance effectiveness or performance efficiency. Multiple regression analyses revealed that the shared aspects of stress and negative affect predicted changes in inhibition following increasing, but not decreasing, PTP. These findings suggest that PTP is an effective manipulation for studying distress and show that EF is sensitive to changes in PTP.

description: The last fifty years of the Soviet era were marked by the ongoing development of policies to monitor religious organizations and their members, with local officials varying in their enforcement of these policies. Despite the Marxist-Leninist line that religion would wither away and some periods seeing harsher anti-religious restrictions than others, religious organizations—including the largest Protestant denomination in the Soviet Union, the Evangelical Christians-Baptists (ECB)—nevertheless persisted and often flourished. Women constituted 70 to 80 percent of ECB congregations’ official membership. And although children and youth were an essential focus of ECB energy, little scholarly work has been done concerning their experiences growing up in the Soviet Union. This dissertation draws upon oral history, extensive archival work, self-published dissident literature (samizdat), and photographs. It examines the lived religion of women and children in the ECB communities of four Siberian provinces in the period from World War II until 1991. The project demonstrates how ECB women’s activism constituted a dual subversion; they facilitated an enduring evangelicalism in the face of hostile state monitoring of and attempted patriarchal hegemony within their congregations. This study also shows that children and youth became a clear battleground due to the symbolic notion of them constituting the “future” for both churches and communists. Throughout this dissertation, sites of ambiguity emerge. Neither the official narrative (“Evangelical women are a constant threat, and their children are problems to be solved.”) nor the standard evangelical narrative (“Soviet authorities are constant evil oppressors.”) was an accurate portrayal of reality. Instead, the lived experience of ECB women and children shows a more complex story than these standard, mutually hyperbolic narratives dared admit.

Subjects: HlyU
Vibrio vulnificus

description: Regulatory proteins from pathogenic bacteria have the potential to serve as novel therapeutic targets. This study discusses the characterization of three regulatory bacterial proteins. First, the HlyU protein of Vibrio vulnificus belongs to the SmtB/ArsR family of metal ion binding repressors and is a global regulator of virulence factors. It has been shown to directly bind a DNA sequence upstream of the transcription start site in the rtxA1 operon and to compete with the repressor H-NS. In this study, a homology model was constructed using the crystal structure of the metallorepressor SmtB from Synechococcus elongatus PCC7942. A high-throughput assay was utilized to monitor DNA binding in vitro. The model structure, metal analysis, and denaturation assays all support the hypothesis that HlyU lacks the key metal ion binding residues of other members of the SmtB/ArsR family. Future studies will determine key residues in DNA recognition and binding and will determine how HlyU is regulated. Second, the Diphtheria toxin repressor (DtxR) is the best characterized member of a family of metal ion-activated repressors involved in metal ion homeostasis, virulence factor expression, and stress response in bacteria. This study presents evidence that DtxR may be involved in an oxidative stress related response system through the oxidation of the metal ion ligand C102. Future studies will determine how, structurally, oxidation of C102 abolishes repressor activity. Third, propionate kinase (PK) from the highly infectious bacterial pathogen Francisella tularensis is a key enzyme in the metabolism of serine and threonine. Previous studies determined a 2.2 Å structure of the apo-enzyme. In this study, structural studies were performed to cocrystallize PK with its substrate in order to better understand the mechanism of phosphate transfer. While crystals with substrate were not obtained, a novel crystallization condition of the apo-enzyme was determined. Future studies will reveal the structure of propionate kinase bound to its substrate.
Profiling the venous leg ulcer population and state of community practice: Designing a nurse-lead leg ulcer service.

Subjects: subject: Health Sciences, Nursing.

description: In order to plan for a new community leg ulcer service, local evidence was required on the regional population with venous leg ulcers and the current state of community practice. There is strong evidence in the literature supporting the assessment and management of venous leg ulcers, but little is known about the local population profile or whether they were receiving the internationally recommended care. This is a manuscript-based thesis that consists of three distinct papers intended for submission for publication. The first two papers detail the planning studies that were undertaken to generate local evidence in order to design a new nurse-led community leg ulcer service. The first paper provides a population profile of the venous leg ulcer population receiving home care in one Ontario region. The second paper provides a critical appraisal of the state of community venous leg ulcer care. In the final paper, an advanced practice nurse (APN) reflects on her role in the design and implementation of the new service. The new leg ulcer service was designed using the evidence from the population profile and to address the gaps and inconsistencies in the provision of "best practice" that were identified in the appraisal of care. In this third paper, a number of barriers to the new evidence-based service were identified on a number of different levels and the multiple strategies tailored to the barriers were described.

description: To investigate the effects of methylmercury (MeHg) on development, Xenopus tropicalis tadpoles were exposed to MeHg diets with concentrations of 0.42 (control), 44 (low), and 270 (high) ng/g wet weight. Increased mortality, decreased metamorphosis, increased size, and a greater number of days between tadpoles reaching metamorphosis were observed in the high MeHg group, suggesting disruption to the thyroid axis. Triiodothyronine levels, however, were not significantly different between groups. In both the control and low MeHg groups, total Hg and MeHg body burdens increased rapidly, reached a plateau and eventually declined with a lower percent MeHg body burden. In the high MeHg group, body burden concentrations increased throughout the experiment. This study demonstrates that at low dosages of MeHg, elimination may prevent toxic exposure whereas at high dosages, demethylation and selective excretion mechanisms may be overwhelmed and disruption of development or death may occur in tadpoles.
Gene expression and splicing efficiency

description: Most eukaryotic protein-coding genes are split into exons and introns, and introns need to be spliced for the production of mature mRNA by pre-mRNA splicing. Pre-mRNA splicing is very important for eukaryotic gene expression, because it is not only a key step in producing mature mRNA, but can also affect transcription and translation. The purpose of this study is to investigate the relationship between gene expression and splicing efficiency since the relationship has not been studied systematically from a bioinformatic approach. In this thesis research, we focus on the question of how gene expression would constrain the evolution of three principal splicing signals: the donor splice site, the acceptor splice site, and the branchpoint sequence (BPS). We chose yeast, Saccharomyces cerevisiae, as the model organism in this study due to its many research advantages such as relatively simple splicing mechanism and extensive genome-wide characterization of gene expression at both transcript and protein levels. We first studied the relationship between gene expression and the strength of the donor and acceptor splice sites in the yeast, with the latter being characterized by position weight matrix scores. We found that donor and acceptor splice sites in highly expressed genes have significantly higher mean, but smaller variance, of splicing strength than that in lowly expressed genes. In addition, genes with extremely low splice site strength tend to be spliced by non-spliceosomal mechanisms, and the last nucleotide on the exon side in the donor splice site (immediately upstream of the 5'GU dinucleotide) is important for splicing. We further studied the relationship between gene expression and BPS in the yeast. The results revealed that the BPS strength of highly expressed yeast intron-containing genes (ICGs) is significantly higher than that of lowly expressed yeast ICGs. Moreover, highly expressed yeast ICGs have significantly longer distance between the donor splice site and BPS (Si distance) and slightly longer distance between BPS and the acceptor splice site (S2 distance) than lowly expressed yeast ICGs. The long Si distance of highly expressed yeast ICG does not indicate the potential of enhancing splicing efficiency through forming secondary structure in the region between the donor splice site and BPS.

description: Voltage stability assessment and control are among the top priority tasks for electric utilities and power system operators. Failure in performing these correctly, has resulted in some of the major blackouts over the past few decades. Continuous loading increase on system infrastructure, higher reliability and security requirements, as well as progressive renewable resource integration, incapable of guaranteeing sustained reactive support, have all made this function more complex, and yet more crucial.Traditionally, developed algorithms for calculating voltage stability margin and recommending the necessary control action, rely on complete and accurate system models, as well as extensive offline studies. Investigating previous incidents has proved this to be a challenging goal to achieve. At the same time, integration of high-sampling measurement devices such as synchrophasors, powerful processors, and fast communication have resulted in increased situational awareness and monitoring quality of the system behavior. As a result, there is high interest today, to develop measurement-based real-time tools for determining system status from stability point of view and deduce the optimal control actions in critical conditions.In this dissertation, accurate modeling of the power system ambient data, corresponding to its operation at quasi steady-state condition is discussed, and the difference between system's steady-state response and power flow solutions is investigated. Based on this clarification, a new distributed model-free algorithm is proposed for voltage stability assessment and control of a power system, based on steady-state Q-V sensitivity of system buses. This is realized through subspace system identification from input-output response based on ambient measurements. Once the sensitivities are known, system proximity to voltage instability can be determined using the minimum sensitivity, rank system buses according to their stability margin and the need for corrective control actions, and determine the optimal set of actions needed to bring system operation point back to a secure state. To pursue the latter, two optimization approaches with different objectives based on various operating policies are introduced towards finding the best local control action within a substation. Finally, an index is introduced to determine vulnerability of the system to voltage instability caused by limitation on a generator's reactive power.

description: Introduction Varicella zoster virus (VZV) causes varicella (chicken pox) and herpes zoster (shingles). Worldwide, these diseases are associated with significant morbidity. Most of the epidemiological data on VZV come from high income countries. There are few data on VZV in Africa, where tropical climates and high HIV/AIDS prevalence rates are expected to impact the epidemiology of VZV. Safe and effective vaccinations for both varicella and herpes zoster exist, but are not routinely used in Africa. There are very few data available on VZV disease burden in Africa to guide the introduction of these vaccines on the continent. Our aim is to conduct a systematic review of the VZV-associated morbidity and mortality in Africa, which will provide critical information that could be used to develop vaccination policies against these diseases in Africa. Methods and analysis Electronic databases will be searched and all studies published after 1974 that meet predefined criteria will be assessed. The primary outcomes for the study are VZV incidence/prevalence, hospitalisation rates and total death rates. The secondary outcome for this study is the proportion of VZV hospitalisations and/or deaths associated with HIV/AIDS. Two reviewers will screen the titles and abstracts, and then independently review the full texts, to determine if studies are eligible for inclusion. A risk of bias and quality assessment tool will be used to score all included studies. Following standardised data extraction, a trend analysis using R-programming software will be conducted to investigate the trend of VZV. Depending on the characteristics of included studies, subgroup analyses will be performed. This review will be reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Ethics and dissemination As this is a protocol for a systematic review, which will use already published data, no ethics approval is required. Findings will be disseminated in peer-reviewed journals.
