Internet telephony services for presence with SIP and extended CPL
Creators: name: Jiang, Dongmei
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2004
Subjects: subject: Computer Science.

description: Internet Telephony is the next generation of telephony with many new features and low cost. Because of the explosion of new features, it has become critical to control and manage these features. The main challenge in Internet Telephony is service programming. The Call Processing Language (CPL) is a solution for end users to describe and control their services in Internet Telephony. Current CPL focuses on call processing services only. It is not adequate for the definition of many types of new services, such as the combination of telephony services with email, instant messaging, presence etc. This thesis extends CPL to describe new Internet Telephony services including presence services and call processing services related to presence. In the thesis, the presence system is systematically described in a three-layer architecture. End user's presence services and system basic services are clearly separated in the architecture. Presence information, as the basis of presence services, is extended from traditional "online" and "offline" indicators to include broader meaning, such as location, phone line status, role and availability status etc. Through CPL extensions for presence, user's new presence services and new presence related call processing services are illustrated by using various examples. A simulation system is implemented to demonstrate the Internet Telephony services specified in extended CPL. End users can create and modify their own services via the Graphic User Interfaces (GUIs) and access their services at any location through the Internet. The simulation system is verified with various test cases.

description: Due to their training, genetic counselors may have a heightened awareness of the many complications which can occur during pregnancy. Previous studies have shown that this knowledge impacts the decisions genetic counselors make during their own pregnancies. The purpose of this study was to clarify the decisions that genetic counselors make during their own pregnancies and assess which factors influence these decisions. We recruited genetic counselors through the NSGC listserv for an anonymous online survey. Participants answered questions about the testing they had done during up to three pregnancies. Participants who worked in a prenatal setting during their pregnancy provided information about any counseling situations which made them uncomfortable. In a total of 313 pregnancies, diagnostic testing was performed in 105 (33.5%), which is a much lower rate than has been previously reported. There was a significant positive correlation between age and rate of diagnostic testing, and a significant negative correlation between calendar year and rate of diagnostic testing. Genetic counselors who worked in a prenatal setting during their pregnancy were significantly more uncomfortable in counseling situations while they were noticeably pregnant than before they were noticeably pregnant, and they were significantly more uncomfortable counseling in person than over the phone. There was not a significant relationship between experience in a prenatal or pediatric setting and the rate of diagnostic testing, and participants’ political views were only slightly significantly related to their rate of diagnostic testing. Participants on average felt that they had a higher anxiety level during pregnancy than other pregnant women. Our findings suggest that genetic counselors may be utilizing diagnostic testing less frequently than previous cohorts. Additionally, future efforts should focus on developing tools to help counselors cope with anxiety during pregnancy.

description: This thesis poses the question, is the Republic (focusing on Books I and V) a work of satire or a sincere work, verging on the utopian? I begin by laying out the basics of the plot and structure of Book I and Book V. In chapter two, I then move to examine a strain of twentieth and twenty-first century thought about the Republic by scholars who adhere to the work of Leo Strauss, a twentieth-century German American political philosopher. I focus primarily on Allan Bloom’s translation of the Republic as well as his accompanying Interpretive Essay, concluding that Straussian method asserts an immutability of human behavior that must interpret the Republic as satire for the work to fit within their general held worldview. Chapter three is an examination of Jo Walton’s 2016 science-fiction and fantasy (SFF) novel, The Just City, which asks the question “What if a group of time travelers actually attempted to create the Republic?” I read Walton’s work through a comparative lens with Strauss and his associates work, as well as alongside Plato’s own writing. I conclude that the Republic is far more beholden to individual human interpretation than most Platonists would like to believe. I also find that these differences in interpretation cause a fundamental crisis of thought: how much of Plato’s work actually contains immutable truth that isn’t subject to human interpretation.
Incorporation of dispersive materials in the envelope finite element (EVFE) method

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2004
Subjects: subject: Engineering, Electronics and Electrical.

description: In this thesis computationally efficient methods of including materials with Lorentz-type dispersion in the envelope finite-element time-domain (EVFE) method are developed and presented. A new perfectly matched layer (PML) mesh truncation scheme, which allows the PML to be applied in Lorentz-type dispersive material has also been derived. These new formulations have been implemented and applied to specific examples, and the approach validated through comparison with results obtained using alternative methods. In particular, it has been demonstrated through the examples that the method developed preserves the large-time-step advantage of the EVFE over the conventional finite-element time-domain (FETD) method.
Zac1, a zinc finger transcription factor, is a direct Pax7 target gene in post-natal myogenesis

description: Pax7 plays an essential role in the commitment, survival and expansion of myogenic progenitors during postnatal muscle growth and regeneration. Recently, our genome-wide expression study in myoblasts identified Myf5 and Zac1 (PlagL1; encoding a zinc-finger transcription factor) as transcripts regulated by Pax7. Zac1 has been previously identified as a tumour suppressor showing anti-proliferative properties through regulation of apoptosis and cell cycle arrest. Zac1 expression paralleled that of Pax7 during myogenic progression, with both genes being expressed at high levels in proliferating primary myoblasts but being rapidly down-regulated during cell-cycle arrest and terminal differentiation. Genome wide protein-DNA interaction profiling and chromatin immunoprecipitation assays have identified a region bound by Pax7 at +11 kb from the Zac1 transcriptional start. This region contains a novel Pax7 consensus sequence that is conserved across species and is functionally activated by the Pax7/FKHR fusion protein. Together these data support the assertion that Zac1 is directly activated by Pax7. Regeneration assays conducted in Zac1-null mice indicate a critical role for Zac1 in mediating efficient regenerative myogenesis. Further elucidation of the functional regulation of Zac1 by Pax7 will provide important insight into the mechanism by which Pax7 defines the cellular phenotype of myogenic progenitors.

description: Early childhood education has been shown to have long-term benefits on education, earnings, and social outcomes. The Head Start program is a free pre-school program that serves low-income children in the United States. I take advantage of sibling fixed effects to explore the effectiveness of the program using data from the National Longitudinal Survey of Youth. Initially, I find positive effects on wealth accumulation for Black Head Start participants. After using a fixed effects reweighting method to address concerns of external validity, I do not find any significant benefits of the Head Start program.

description: Accurate DNA replication is essential for faithful transmission of hereditary information throughout all kingdoms of life. A mistake in DNA replication can lead to accumulation of mutations that are often deleterious to the life of an organism. Eliciting mechanisms in which mutations arise is vital for disease prevention and treatment. Mutational hotspots exist at imperfect inverted repeats, quasi-palindromes, which get perfected by mutagenesis. Given the “patchy” nature of quasi-palindromic sequences it is quite difficult to identify them bioinformatically and therefore quasi-palindrome associated mutations have remained an understudied class. The proximity of inverted repeats makes it possible for newly synthesized DNA to misalign and form a complementary hairpin that polymerases can incorrectly use as a template. Template-switch mutagenesis has been implicated in cancer and Duchenne muscular dystrophy. Replication proteins are highly conserved from bacteria to humans allowing for the Escherichia coli model system to be used in illumination of quasi-palindrome mutational avoidance and its stimulation by pharmacological mutagens. The work described quantifies the activity of Exonuclease I and Exonuclease VII in quasi-palindrome premutagenic avoidance using a novel template-switch specific E. coli strain reporter in lacZ. The activity of the Exonuclease I is in a strand-specific manner, assisting avoidance of mutation on the lagging strand. This work also uncovered that 5-azacytidine, an FDA-approved cancer treatment drug, stimulates quasi-palindrome events. The aim is to uncover how quasi-palindrome mutations are avoided and stimulated, potentially leading to improvements in clinical treatments or prevention.
Numerical simulation of slag foaming with reaction kinetics in oxygen steelmaking
Creators: name: Kirindigoda Hewage, Anuththara
Publisher: name: Swinburne
Year: 2024

description: A CFD model was developed to predict the slag foaming and the rates of major chemical reactions in oxygen steelmaking. Slag foaming is a phenomenon that needs to be properly controlled for a continuous and efficient process, and the knowledge on the chemical reactions is essential for that. Hence, the results obtained from the CFD model in this study are a strong step towards developing a general CFD model for oxygen steelmaking process. A general CFD model of oxygen steelmaking process as such will be able to predict every aspect of the process facilitating the operators to pre-define the optimal process conditions and optimum required raw material quantities and energy requirements.
Dietary risk factors for testicular cancer

description: Although testicular cancer is a relatively rare cancer in Canada, accounting for only 1.1% of all malignant neoplasms in males, it is the most common cancer among men 20 to 45. Understanding of the causes of testicular cancer risk in general, and the association with diet in particular, remains limited. Data from the National Enhanced Cancer Surveillance System were used to explore the relationship of diet and testicular cancer risk. There were 601 cases of testicular cancer and 744 controls available for study. We systematically examined 17 food groups, 15 nutrients, and 7 individual foods based on data collected through a 69-item food-frequency questionnaire. Our results suggest that higher dairy product intake, specifically cheese, is associated with a higher risk of testicular cancer in Canadian males. Risk differences were observed between histological subtypes of testicular cancer. This thesis provides a basis for future studies designed to address testicular cancer etiology.

description: In today's political era, interest groups are infamous for their ability, both real and perceived, to affect political outcomes. Because interest groups are so influential, it is all the more important to understand how exactly they function and influence politics. One set of influence strategies deals in mobilizing their members to take political action, which is called outside lobbying. However, the existing literature does not have an answer as to what interest groups can do to maximize their mobilizational effectiveness. For this reason, this thesis seeks to answer the question of what tactics and strategies that are available to interest groups are the most effective at inducing political mobilization. This thesis seeks to answer this question through an in-depth comparative case study of the NRA and Everytown by analyzing what incentives they offer to their potential and existing members and how those offerings affect mobilization. The findings showed that because the NRA offers more types of incentives, including the offering of a shared social identity, they are able to utilize two special mobilizational tactics called shifting and urgency, which consistently boost their mobilizational efficacy to a very high level. In contrast, Everytown is less consistently effective at mobilization because they, for the most part, only offer purposive incentives, and as such are unable to use shifting and urgency. These findings show that what a group offers to its potential and existing members has immense effects on a group's mobilizational efficacy.

description: Within the emergent study of the complex relations between the State of Israel and American Christianity is a little-known story of a Mormon-American leader whose friendship with the nascent Jewish State spanned nearly five decades. Ezra Taft Benson, apostle in the Church of Jesus Christ of Latter-day Saints (commonly referred to as Mormons) from 1943-1994, also served as Secretary of Agriculture in President Dwight D. Eisenhower's cabinet from 1953-1961. During that time, and thereafter, he proclaimed his assurance, both to his Mormon followers and to the world, of the State of Israel's miraculous fulfillment of Biblical prophecy. Likewise, through his political leadership he created lasting friendships with early Israeli leaders, particularly David Ben Gurion. His interest in the fate of the Jewish people was relatively representative of his Latter-day Saint heritage, but his relationship with Israeli leaders, as well as his consistently zealous message of religious-based support for the State of Israel, made him distinctive among both religious and political leaders of his day.

description: Ultracold atoms have been successfully trapped in an array of magnetic micro-traps with a period of 700 nm based on patterned permanent magnetic film. The created atomic lattice system is analogous to a crystal lattice in a solid material. The study of this well-controlled atomic lattice system in lab helps us to understand the behaviour of more complicated solid materials. This may contribute to the creation of new types of materials in the future.
The regulation of intestinal epithelial cell proliferation by 1,25-dihydroxyvitamin D(3) and transforming growth factor beta.

description: The effects of the active metabolite of vitamin D$\sb3$, 1,25 (OH)$\sb2$D$\sb3$, and of transforming growth factor $\beta$1, TGF$\beta$1, on the proliferation and differentiation of an epithelial cell line derived from the rat small intestine (IEC-6) were investigated. IEC-6 cells contain the vitamin D receptor, which is upregulated by serum. TGF$\beta$1 has no effect on the activities of two markers of differentiation, alkaline phosphatase and sucrase. However 1,25 (OH)$\sb2$D$\sb3$ elevates alkaline phosphatase activity 8.9-fold within 72 hours. Both 1,25 (OH)$\sb2$D$\sb3$ and TGF$\beta$1 inhibit DNA synthesis in a concentration-dependent manner. Within 24 hours, 0.8 ng/ml TGF$\beta$1 and 500 nM 1,25 (OH)$\sb2$D$\sb3$ reduce $\sp3$H-thymidine incorporation by 55% and 60% respectively. A transient time course of DNA synthesis results from TGF$\beta$1 treatment while 1,25 (OH)$\sb2$D$\sb3$ treatment produces a sustained effect. The effect of 1,25 (OH)$\sb2$D$\sb3$ on DNA synthesis is partially blocked with neutralizing antibodies to TGF$\beta$ which suggest that active TGF$\beta$ is produced in response to 1,25 (OH)$\sb2$D$\sb3$. TGF$\beta$1 induces an accumulation of cells in the G$\sb0$G$\sb1$ phase of the cell cycle while 1,25 (OH)$\sb2$D$\sb3$ does not. However both 1,25 (OH)$\sb2$D$\sb3$ and TGF$\beta$1 inhibit the phosphorylation of the product of the retinoblastoma tumor suppressor gene. In conclusion, we have shown that 1,25 (OH)$\sb2$D$\sb3$ is a potent inhibitor of intestinal epithelial cell proliferation and have obtained indirect evidence to support a role for TGF$\beta$ in this effect. We speculate that modulation of IEC-6 cell proliferation may involve TGF$\beta$, whereas effects of 1,25 (OH)$\sb2$D$\sb3$ on differentiated markers, such as alkaline phosphatase, are mediated independently of TGF$\beta$.

description: Duchenne muscular dystrophy (DMD) is a progressive and life-limiting neuromuscular condition that impacts not only the affected individual, but the entire family unit. After receiving a DMD diagnosis in a child, parents are quickly tasked with disclosing information about the condition to other family members, especially unaffected siblings. Parents have reported that healthcare providers are unhelpful at providing specific advice on how to best navigate these difficult conversations, probably due to lack of research on this topic within academic literature. This study aimed to explore the optimal methods to communicate information about DMD with unaffected siblings in the family. Through an anonymous online survey, adolescents and young adults who have a brother with DMD were asked how they first learned about their brother’s diagnosis and whether they wished anything had been communicated with them differently. Analysis of survey data revealed that the majority of participants were satisfied with how information was communicated in their family. However, most siblings wished they learned more information about certain topics like treatment options or genetics during the initial disclosure, and stressed the importance of open and honest communication by parents. It may be beneficial for certain children to speak with a healthcare provider either during or after the initial disclosure for additional information and support. This study provides valuable insight into how, when, and what siblings prefer to learn about DMD such that medical professionals, like genetic counselors, may best assist parents with navigating the disclosure process within their family.
Acute effects of exercise timing and breakfast meal glycemic index on exercise-induced fat oxidation

description: To examine the acute effects of exercise timing and meal glycemic index (GI) on fat oxidation and glycemic response, five apparently healthy young men participated in four randomly ordered morning trials during which measurements were made at rest, during exercise, and for two hours post-exercise. A factorial design [exercise timing (pre-prandial, post-prandial) x meal GI (low-GI, high-GI)] was used for repeated measures of energy expenditure and whole-body fat oxidation, as well as of plasma glucose and insulin levels after an overnight fast. Subjects were required to perform 400 kcal of moderate treadmill exercise either before consuming a 400 kcal low-GI (ELG) or high-GI (EHG) oatmeal breakfast, or after consuming the low-GI (LGE) or high-GI (HGE) meal. Exercising fat oxidation was significantly greater during ELG and EHG (14.7 +/- 1.4 and 14.8 +/- 3.2g, respectively) than during LGE and HGE (8.9 +/- 3.1 and 9.8 +/- 2.7g, respectively) (p < .001), as was total fat oxidation beyond rest and (ELG: 21.3 +/- 3.7g; EHG: 20.2 +/- 5.9g; LGE: 18.1 +/- 6.0g; HGE: 17.1 +/- 3.4g) (p < .05), although energy expenditure was unaffected by experimental conditions. No significant effect of meal GI on fat oxidation was observed and, unexpectedly, the glycemic response was not significantly different across experimental conditions. Total whole-body fat oxidation for the entire morning period is therefore greatest when exercise is performed in the post-absorptive state, a strategy that could help maximize acute exercise-induced fat oxidation.

description: Guidelines for the clinical management of individuals born with disorders of sexual development (DSD) were established with the publication of the 2006 DSD Consensus Statement. The purpose of this study was to explore the experiences of parents of children born with ambiguous genitalia due to DSD and to examine their perceptions of the medical care they received in relation to the DSD Consensus Statement. We conducted semi-structured telephone interviews with eight parents whose children were born with ambiguous genitalia who were between the ages of three months and ten years. Five main themes emerged from the interviews: 1) communication with healthcare professionals (HCPs), 2) experience and expertise of HCPs, 3) coordination of care, 4) sources of psychosocial support, and 5) role of the Internet for information. While parents reported generally positive experiences with regard to the experience and expertise of their HCPs, they reported an almost equal number of negative as positive experiences regarding communication. Only two parents reported receiving their medical care through an established specialized multidisciplinary team. Most parents assembled their own medical team with variable success in coordinating the care among the different specialists. Psychosocial care provided by mental health staff with expertise in DSD was available only to parents who received their care through established multidisciplinary teams. The Internet played an important role for most parents by providing peer support, guidance in decision-making, and education. Our findings suggest that increased availability of established multidisciplinary teams and better communication between parent and HCPs could improve care and relieve stress placed on families.
Government French language training programs: Statutory civil servants' experiences
Creators: name: Bessette, Josee

Year: 2005
Subjects: subject: Education, Bilingual and Multicultural.
subject: Political Science, Public Administration.

description: This collective case study explores second language (L2) training experiences from the perspectives of six Canadian statutory civil servants and examines factors that may have influenced their L2 learning experience. Three instruments were used to collect data: a preliminary questionnaire, an in-depth questionnaire, and an interview protocol. Findings reveal that a language and culture connection, opportunities to use the L2, and a short-term intensive cultural and linguistic immersion experience in particular were all associated with more positive L2 learning experiences. Negative comments regarding L2 learning experiences revolved around the anxiety and stress surrounding the one-shot summative nature of the oral exam, and seemingly no link between instruction and evaluation. This research contributes to the growing literature on factors affecting the L2 learning processes and outcomes.

description: Field pea (Pisumsativum L. ssp. sativum) is a universal pulse crop. One of the actual problems in its production is the influence of weather condition on the variability of pea economic characters and its properties. The purpose of the research (2009–2018) was to compare the vegetation period and interstage periods of the Hangildin and Chishminskiy 229 pea varieties with weather condition and seed yield. According to the results of the conducted research, it can be seen that the duration of the vegetation period and the yield of field pea grain was influenced by weather condition. The average daily air temperature affected the duration of the sowingsprouting period in pea varieties Hangildin and Chishminskiy 229. The duration of the two periods (sprouting-flowering and flowering-ripeness) was influenced by features of the used varieties and the temperature condition (r = -0.472, the link is significant and r = -0.788). The duration of the sprouting-ripeness period depended on the average daily temperatures (r = -0.481), the amount of precipitation (r = 0.937), and the HTC (hydrothermal coefficient) (r = 0.927). Precipitation increased the duration of the full vegetation period (r = 0.892). On average, over 10 years of research on field pea it should be noted that there wasa close relationship between the duration of its vegetation period (r = 0.844), the duration of the flowering-ripeness period (r = 0.679) and the yield of seeds. The relationship between the seed yield and the sowing - sprouting period (r = 0.451) and between the seed yield and the sprouting - flowering period (r = 0.446) was revealed. The connection was found positive. The connection with the average daily air temperature of this period was negative (r = -0.213). The results of the research can be successfully used during cultivation of domestic and foreign varieties of field pea. In international practice, the results of this experiment can be successfully applied in selective improvement of field pea and the development of new, high-tech varieties.
Recovering repetitive sub-functions from observations in distributed systems
Creators: name: Wang, Shen
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2007
Subjects: subject: Computer Science.

description: Since many distributed systems are developed without complete or consistent design documents, some relevant designs need to be recovered from the executable software itself. One important objective of reverse engineering is to synthesize meaningful high-level design abstractions from the observations of a subject system. Algorithms, which, given a set of observations of an individual functionality of an existing distributed system, construct, under specific assumptions, a high-level design abstraction represented by an MSC-graph where repetitive sub-functions are identified, have already been proposed. In this thesis, we propose a new algorithm (based on the previous algorithms) that waives the strongest assumption made in the previously published work, and it is capable of recovering several repetitive sub-functions at once. Consequently, it is easier to generate observations for constructing a high-level design abstraction represented by an MSC-graph by using our proposed method. The resulted MSC-graph can then be used to facilitate the system maintenance or evolutionary development.

A cycloaddition approach to substituted anthraquinone systems as potential antitumor agents.
Creators: name: Pham, Thi Tham.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1996
Subjects: subject: Chemistry, Organic.

description: In the cycloaddition approach towards the synthesis of the substituted anthraquinone derivative 8 as a potential antitumor agent, it was found that the tricyclic core of this target analogue could be generated by an intramolecular Diels-Alder reaction. The Diels-Alder precursor 34 was successfully synthesized starting from 3-methyl benzyl alcohol, metha-crolein and (2Z)-2-(ethenyl)-3-iodo-1- (p-methoxybenzyloxy)-2-propene; it readily underwent cycloaddition at approximately 40$\sp\circ$C to generate a cis-fused ring system 35. The stereochemistry of the cycloaddition product was unambiguously determined by X-ray structure of crystalline 41. Stereo-selective epoxidation of the ring C double bond with m-chloroperoxybenzoic acid was achieved for diol 48, where the functionality at C2 was a hydroxyl group. The synthesis of anthraquinone derivative 47b is also described.* ftn*Please refer to the dissertation for diagrams.

Examining the use of evidence-based practice resources among physiotherapists in Canada
Creators: name: Judd, Maria Gail Paumann
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2004
Subjects: subject: Engineering, System Science.

description: Objective. To assess physiotherapists' awareness of, access to, and use of evidence-based practice (EBP) resources and factors that influence their use in practice. Methods. A postal survey of a random sample of 321 Canadian physiotherapists. Open and closed-ended questions were used to elicit participants' views on EBP, EBP resources, and barriers and facilitators to research use. Results. Two hundred and thirty-four of the 301 eligible physiotherapists responded (77.7% response rate). Attitudes towards EBP were positive. Sixty two percent of participants had access to the Internet in their practice setting. Sixteen percent had read a Cochrane review, 15% were aware of Cochrane reviews but had not read one, and 59% were unaware of the Cochrane Library. Even fewer physiotherapists were aware of other EBP resources such as the PEDro. Participants reported major barriers to using research included lack of time (64%) and relevant literature not being compiled in one place (61%). The trustworthiness of the research message was positively associated with EBP resource use. Conclusions. Physiotherapists have positive attitudes towards EBP and want relevant literature compiled in one place. However, a high proportion of respondents were unaware of several high-quality EBP resources. This suggests that information about the availability of EBP resources is not being adequately disseminated to Canadian physiotherapists. Efforts are needed to ensure widespread dissemination of EBP resources.

description: L’insegnamento della lingua araba pone da sempre un grande dilemma: quale arabo insegnare, l’arabo letterale standard o l’arabo colloquiale? Avere una reale competenza che permetta di assolvere differenti attività comunicative richiede una formazione in entrambe le varietà. Tuttavia non è semplice progettare corsi che centrino in maniera efficace ed esaustiva questo obiettivo. Ciò è ancora più vero se essi sono destinati a un pubblico adulto che vorrebbe, attraverso la conoscenza dell’arabo, accrescere la propria professionalità per adempiere a mansioni operative specifiche. Si propone quindi una riflessione sui metodi di insegnamento e di certificazione dell’arabo in ambito militare.

The CRISPR-Mediated Gene Disruption of the Metal-Responsive Transcription Factor-1 (MTF-1) For the Purpose of Creating a Human Knockout Cell Line

description: The metal-responsive transcription factor-1 (MTF-1) is responsible for regulating the transcription of a cohort of genes, most prominently those involved in the regulation of heavy metal and oxidative stresses. Normally found in both the nucleus and cytoplasm, when MTF-1 encounters excess zinc, either directly through free zinc ions, or indirectly, through its cadmium- or peroxide-triggered release from metallothioneins, it rapidly localizes to the nucleus, where it binds to the promoters of its target genes at conserved “metal-responsive elements.” From there, it can recruit coactivators and general transcriptional machinery to positively regulate gene expression. MTF-1 and several of its target genes have been shown in previous literature to be irregularly expressed in cancer. Our objective in this experiment was to utilize the CRISPR method of gene editing to create a human MTF-1 knockout cell line, so that cancer-associated mutations of MTF-1 can be studied further. The goal of targeting the MTF-1 has been realized. HEK293 was transfected with four guide RNA plasmids for targets located on the first exon of MTF-1, with the goal of generating a premature stop codon that would eliminate translation of the essential nuclear import, DNA-binding, and transactivation domains of MTF-1. T7 Endonuclease assay data demonstrates that transfection and targeting were both highly efficient, with nearly fifty percent of the cell culture possessing a lesion at the CRISPR targets.

The use of the FDTD method for electromagnetic analysis in the presence of time-varying media
Creators: name: Liu, Xiaowen
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2004
Subjects: subject: Engineering, Electronics and Electrical.

description: In this thesis a straightforward means of including independently time-varying material properties in finite-difference time-domain (FDTD) formulations is presented. The approach is systematically applied to three classes of problems, namely electromagnetic wave propagation through a medium with time-varying permittivity, electromagnetic wave propagation along a medium with time-varying permittivity, and electromagnetic wave radiation from a source on a medium with time-varying permittivity. The first-mentioned class of problem has received limited attention in the literature either analytically or numerically. The second and third classes have received virtually no attention in the literature using any approach prior to the present study. By carefully selecting examples from the above-mentioned classes of problem the correctness of the FDTD predictions for these examples has been confirmed in spite of the unavailability of precise analytical solutions (due to the inherent difficulty of finding such solutions for time-invariant problems in electromagnetics) or experimental results (due to the fact that appropriate materials are not yet extant).
